UMBRELLA WITH FAN AND RETRACTABLE FAN GUARD

Abstract

An air fan is secured between two protective cowlings to a lower rib or a stretcher of a patio umbrella or parasol. An actuator mechanism, which may include a Hall sensor, ensures that the fan blades remain parallel to the lower rib (or stretcher) and do not rotate so as not to interfere as the umbrella or parasol is folded. An optional retractable fan guard includes a sliding part that depends from the first cowling and a fixed part that depends from the second cowling, a series of flexible rods linking the sliding part and the fixed part, and a pull cord. The pull cord is fixed at one end to the sliding part, is threaded through the fixed part and is secured at its opposite end to a rib of the plurality of ribs supporting the canopy. The flexible rods bow when the pull cord is tensioned creating a guard screen. The flexible rods straighten when tension is released, facilitating closure of the umbrella or parasol with the air fan still secured to the lower rib.

[0091] Referring now to FIG. 1, there is shown an illustration of an embodiment of a parasol fan structure 99 comprised of a center pole comprising pole portions 3a, 3b and a plurality of ribs 7, each rib 7 is attached to a strut 6, 6a. In the example disclosed, the parasol fan structure 99 further comprises a base 10a with a base tube 10b, a lower hub 4, an upper hub 5, a plurality of the presently disclosed attachable fan devices 12, a control unit 13, and electrical wiring 16 comprising an electrical connector 40. In any of the embodiments disclosed herein, an electrical connector may be any type of electrical plug, a plug, any type of electrical socket, a socket, or a plug and a socket (for example, a contact part on Printed Circuit Boards (PCBs)).

[0092] In the embodiment shown in FIG. 1, the parasol fan structure 99 is a structure for a center pole parasol that includes a canopy 2a, 2b (exemplified in FIG. 17), vent(s) 8, and a rope 11. Rope 11 is part of an adjust system which is further discussed below and which is designed for opening and closing the parasol fan structure/assembly 99, 100 (assembly 100 is exemplified in FIG. 17), raising, and lowering the canopy 2a, 2b, and securing the parasol fan structure/assembly 99, 100 in an open or closed configuration.

[0093] In some embodiments, at least one strut 6a, 6b of the parasol fan structure/assembly 99, 100 comprises the presently disclosed attachable fan device 12. Struts which comprise the attachable fan device 12 comprise two opposing strut portions 6a, 6b, a first strut portion 6a is attached to the rib 7, and a second strut portion 6b is attached to the lower hub 4, and the two opposing strut portions 6a, 6b are attached to the attachable fan device 12 therebetween. In the embodiment wherein the parasol fan is a center pole type parasol fan (as shown in FIGS. 1-3), the attachment of the struts/strut portions 6, 6a to the ribs 7 is a pivotal attachment achieved via attachment of each rib 7, and strut/strut portions 6, 6a coupled to it, to joint 41. In some embodiments (shown in FIGS. 1-3, 23), the attachment of the second strut portion 6b to the lower hub 4 is a pivotal attachment. Additionally, in the embodiment shown each rib 7 of the plurality of ribs 7 comprises a first end and a second end. The second end is coupled to the canopy 2a, 2b (depicted in FIG. 16), and the first end is pivotally attached to the upper hub 5.

[0094] The attachable fan device 12 is shown attached to a plurality of strut portions 6a, 6b of the parasol structure 99, for example, to four pairs of strut portions 6a, 6b. In some embodiments, the attachable fan device 12 is oriented such that air is blown by the blades 17 of the attachable fan device 12 toward an area underneath or near the canopy 2a, 2b (as depicted in FIG. 17), e.g., toward a user sitting underneath the canopy 2a, 2b. In this manner, while the canopy 2a, 2b is in an open configuration and the attachable fan device 12 operates, air is blown such that an individual sitting underneath the canopy 2a, 2b, or otherwise near the fan device 12, is fanned by the blown air and is better able to stay cool to limit perspiration or to prevent overheating. As another example of use of the attachable fan device 12, a smoker might sit in a chair underneath the canopy 2a, 2b, such that the attachable fan device 12 blows air to displace smoke away from other people who may be near the smoker and who may not desire to breathe or be exposed to smoke.

[0095] As is further discussed herein, the fan blades 17 of the attachable fan device 12 are configured to be positioned parallel to the strut portions 6a, 6b when the fan blades are not rotating, or stopped from rotating. Therefore, the attachable fan device 12 may be kept attached to the strut portions 6a, 6b of the parasol, when the parasol fan structure/assembly 99, 100 is in an open configuration (as shown in FIG. 17) or in a closed configuration (i.e., folded into a compact configuration for storage or transport of the parasol fan structure/assembly, e.g., when not in use) (as shown in FIG. 34).

[0096] In some embodiments, pole portion 3a is attached to the base 10a, 10b, the attachment may be a reversible attachment. In some embodiments, the parasol fan structure 99 comprises a control unit 13, the control unit comprises at least one switch 33. In the embodiment exemplified in FIG. 1, switch 33 is operably connected to the function of the at least one attachable fan device 12. In some embodiments, the control unit 13 comprises a plurality of switches 33, each switch 33 is operably connected to the function of one attachable fan device 12 (e.g., the attachable fan device 12 positioned substantially above the switch 33 being operated). In some other embodiments, one switch 33 is operably connected to the function of more than one attachable fan devices 12.

[0097] In some embodiments, the control unit 13 also includes a charge port 32 to allow a user to charge a personal electronic device, such as a cell phone, tablet, etc. In some embodiments, the control unit 13 is electrically powered via electrical wiring 16. In the example shown, the electrical wiring 16 providing electricity to the control unit 13, runs from under the base 10a through an opening 42 (depicted in FIG. 4b) in the circumference of the base 10a, through the base tube 10b and toward the control unit 13 through the center pole 3a. In some embodiments, the base 10a is hollow and in some other embodiments, base 10a comprises a groove (not shown) designed for fitting an electrical wire 16. The end of electrical wire 16 which is outside the base 10a and the parasol fan structure 99 comprises an electrical connector 40. Electrical connector 40 is designed to be operably connected into any electrical socket/plug. In some embodiments, electrical connector 40 is operably connected to a power brick. In some embodiments, pole portion 3a further comprises opening 43 positioned proximal to its end which is attachable to the base 10a, 10b. Opening 43 is further discussed herein.

[0098] While a center pole parasol is shown, other types of parasols, parasol configurations, shading structures are contemplated and may be used without departing from the scope of this invention and disclosure. See, for example, the cantilevered patio umbrella shown in FIG. 43 and discussed in greater detail below.

[0099] Referring now to FIG. 2, there is shown perspective view a portion of the parasol fan structure 99 of FIG. 2. It is expressly contemplated herein that the attachable fan device 12 may be attached to any part of the parasol fan structure/assembly 99, 100, or indeed to any part of an applicable structure. However, in the shown configurations, the attachable fan device 12 is attached to strut portions 6a, 6b of the parasol fan structure/assembly 99. 100. The attachable fan device 12 is shown in an off state such that the fan blades 17 are parallel to the strut portions 6a, 6b of the parasol fan structure. When the attachable fan device 12 is in an off state (does not operate) the parasol fan structure/assembly 99, 100 may be folded (also referred to herein as closed) and unfolded (e.g., unclosed or opened), canopy 2a, 2b lowered, and raised without damaging the fan blades 17 and without the fan blades 17 damaging the parasol structure/assembly 99, 100 or parasol canopy 2a, 2b.

While in the shown embodiments wired power delivery and wired control of power delivery to the attachable fan device 12 from the control unit 13 are implemented, alternate configurations and implementations are envisioned as described elsewhere herein.

[0103] FIG. 3 depicts a partly exploded view of the portion of the parasol fan structure illustrated in FIG. 2. In some embodiments, the pole, such as a center pole, comprises two opposing pole portions, 3a, 3b. A first pole portion 3a is attached on a first end to the base 10a, 10b, and on a second end to the control unit 13. A second pole portion 3b is attached on a first end to the control unit 13, and on a second end to the upper hub 5 or upper joint. In some embodiments, control unit 13 comprises at least one opening 47 proximal to each end. In some other embodiments, control unit 13 comprises a pair of opposing openings 47 proximal to each of its ends. By opposing openings, it is meant that a securing means as defined herein can be inserted into one of the openings and then be inserted into the other one, so that it is inserted simultaneously in both. In the example shown, pole portion 3b comprises opening 46 proximal to its first end. In other embodiments, pole portion 3b comprises two opposing openings 46 proximal to its first end. In some embodiments, the attachment of the control unit 13 to pole portions 3a and 3b is accomplished by aligning openings 46 and 47 so that they overlap and securing them together via a securing means going through them. The securing means may be, without limitation, a nail, a screw, a rivet, a tack, a pin, a bolt, a dowel (such as a metal dowel), or combinations thereof. In the embodiments when the parasol fan structure/assembly 99, 100 comprises a plurality of switches 33 and a plurality of attachable fan devices 12, and each switch 33 is operably connected to one attachable fan device 12, the attachment of the control unit 13 to pole portion 3b is such that the switch 33 operating a certain attachable fan device 12 is positioned substantially beneath it. This way, if one user sitting underneath a parasol fan assembly 100 which comprises a plurality of attachable fan devices 12 wishes to operate just the one attachable fan device 12 most directly above her/him, she/he can do so by switching on the switch 33 closest to her/him. Additionally, according to some embodiments, the pivotal attachment of struts 6 and 6b to the lower hub 4 is accomplished using opposing openings 45 as is further discussed and depicted herein. In some embodiments, the pivotal attachment of ribs 7 to the upper hub 5 is accomplished using opposing openings 44 as is further discussed and depicted herein.

[0104] Referring now to FIG. 4A, a portion of the parasol fan 99 is illustrated depicting the control unit 13 attached to pole portion 3a which is attached to base tube 10b and base 10a. Opening 42 in base 10a allows for the passage of electrical wiring 16. Alternatively, electrical wiring 16 does not pass through the base 10a, 10b, but is inserted into/exits pole portion 3a directly via opening 43.

[0105] FIG. 5 depicts a partly exploded illustration of the control unit 13, pole portion 3a, and base 10a, 10b. Electrical wiring 16 passes via opening 42, and underneath the base 10a and inside base tube 10b (not shown), and out of base tube 10b to go inside pole portion 3a. Opposing openings 47 positioned proximal to the bottom end of control unit 13 are designed to align and overlap with opposing openings 46 positioned proximal to the second end of pole 3a. Control unit 13 is attached to pole portion 3a by the use of a securing means inserted through aligned and overlapping opposing openings 46 and 47.

[0106] While a securing means and designated openings for the use of a securing means are depicted herein, other methods for the attachment of a center pole, or pole portions 3a and 3b, to the control unit 13 are envisioned herein. For example, spring operated raised tabs designed to fit and lock into matching openings may be used (not shown). Alternatively, sleeves may be configured to engage the body of the control unit 13 along with customized inserts. For example, the inserts may be sized and configured to securely contact a particular corresponding structure, such as a pole portions 3a, 3b of a particular parasol or umbrella, and in this manner, there may be provided different inserts that are particularly configured for attachment to different structures and other components, such as the mentioned-above sleeves and the control unit 13, may be standardized or manufactured to certain specifications (not shown).

[0107] Pole portion 3b is illustrated in FIG. 6, attached to the upper hub 5 and slidingly attached to the lower hub 4. An example of an adjust system designed for opening and closing the parasol fan structure/assembly 99, 100 (assembly 100 is exemplified in FIG. 17), raising, and lowering the canopy 2a, 2b, and securing the parasol fan structure/assembly 99, 100 in an open or closed configuration is depicted. The adjust system comprises rope 11 and pulleys 14. In some embodiments, the upper hub 5 and the lower hub 4 each comprise one pulley 14, the pulleys 14 are vertically aligned and facing each other and designed for use together, along with rope 11, to adjust the distance of the lower hub 4 relative to the upper hub 5. In some other embodiments, the upper hub 5 and the lower hub 4 each comprise two pulleys 14. Each pulley of the two pulleys 14 on each hub 4, 5 are opposing each other horizontally on the internal circumference (the circumference which is around, and proximal to, pole portion 3b) of the hub 4, 5. According to this embodiment, each of the two pulleys 14 of the upper hub are designed for use with a pulley 14 of the lower hub 4 which is vertically aligned to it and faces it, and along with rope 11, facilitate adjustment of the distance of the lower hub 4 relative to the upper hub 5. The lower hub further comprises pin 15 which can be inserted to opening 36 (depicted in FIG. 10) in pole portion 3b and secure the lower hub 4 in a desired position. Portion 37A of the parasol fan structure 99 (see FIG. 6) is further depicted in FIG. 7 while portion 38A (see FIG. 6) is further depicted in FIG. 10.

[0108] While an adjust system comprising a rope 11 and pulleys 14 is exemplified for the purpose of opening, closing, raising, and lowering the canopy 2a, 2b of the parasol fan assembly 100, any type adjustment system traditionally used in the art to position a parasol/umbrella structure in an open or closed configuration applies to the presently disclosed parasol fan structure/assembly 99, 100. For example, the adjust system may comprise, without limitation, levers, pulleys, ropes, tabs (e.g., tabs fitting into assigned openings), springs, frictional fits, pins (e.g., pins fitting into assigned openings), nested telescoping sections, and combinations thereof.

[0109] Depiction of portion 37A (see FIG. 6) is illustrated in FIG. 7. The upper hub 5 comprises brackets 48 comprising pins 49 designed for pivotal attachment to opposing openings 44. Pin 49 may be any applicable securing means. Pulley 14, and a rope 11 coupled to it, is depicted. An example of the upper hub 5 is further depicted in FIG. 8, showing multiple electrical wiring 16 coming out of the upper hub 5, each electrical wiring comprising an electrical connector 40. FIG. 9 is an exploded view of the presently disclosed upper hub 5 depicting cap 50, top cover 51, and bottom cover 52. The bottom cover 52 comprises two opposing pulleys 14. The upper hub 5 comprises a plurality of brackets 48 comprising pins 49. The number of brackets 48 corresponds to the number of ribs 7 that the parasol fan structure/assembly 99, 100 comprises. In the illustrated examples herein, the parasol fan structure/assembly 99, 100 comprises eight ribs 7, and four of the eight ribs 7 are pivotally attached to struts 6a which are attached to the attachable fan device 12. In some embodiments, the ribs 7 which are pivotally attached to strut 6 and the ribs 7 which are pivotally attached to ribs 6a alternate.

[0110] In some embodiments, the upper hub 5 comprises a PCB 53 and electrical wiring 16 from the control unit 13 electrically connects to the PCB 53. In the embodiment of FIG. 9, the PCB 53 comprises an electrical connector 57 designed for electrical connection to the electrical wiring 16 from the control unit 13, and electrical connectors 56 electrically connected to electrical connector 57. Electrical connectors 56 in turn electrically connect to electrical connectors 40 of the electrical wiring 16 coming out of the upper hub 5 and running along, or inside, ribs 7. Bottom cover 52 and PCB 53 comprise a central opening 55. The central opening 55 is designed to fit an end of the pole portion 3b inside the upper hub 5 and to allow electrical wiring 16 from the control unit 13 to enter the upper hub 5. In some embodiments, according to which the upper hub 5 does not comprise a PCB 53, electrical wiring 16 from the control unit 13 enters the upper hub 5 via opening 55 and from there it runs along, or inside, each rib 7 which is pivotally attached to strut 6a. in the embodiment illustrated, electrical wiring 16 from the control unit 13 enters the upper hub 5 via opening 55 and there it electrically connects to electrical connector 57. Electrical wiring 16 comprising electrical connectors 40 that electrically connect to electrical connectors 56 and pass through openings 54 in brackets 48 to run along, or inside, each rib 7 which is pivotally attached to strut 6a. Further, when top cover 51 and bottom cover 52 are assembled they define between them openings 85 for the passage of the electrical wiring 16, wherein wiring 16 is passed first through opening 54. In some embodiments, PCB 53 further comprises electrical connector 58 which is further discussed herein.

[0111] Top cover 51 and bottom cover 52, when assembled together, define ridges 88, 89. And, ridges 88, 89 define between them grooves 86, from which bracket 48 projects outside of the top hub 5. It is noted that the sides/walls of grooves 86 are not even, and therefore brackets 48 are projected outside of the top hub 5 in an offset angle. Therefore, the ribs 7 pivotally attached to the brackets 48 via pins 49 are also at an offset angle relative to the center pole 3a, 3b, meaning that a line running along the top, or inside, of rib 7, and projecting straight from it, would not pass through the center point, or substantially center point, of pole portion 3b or the center point, or substantially center point, of the upper hub 5. Similarly, the top cover 80 and bottom cover 81 of the lower hub 4 (FIG. 29), when assembled together, define ridges 88, 89 which are vertically parallel to ridges 88, 89 of the upper hub 5. Ridges 88, 89 of the lower hub 4 define between them grooves 86, from which bracket 48 projects outside of the lower hub 4. As with the upper hub 5, the sides/walls of grooves 86 are not even, and therefore brackets 48 are projected outside of the top hub in an offset angle. Grooves 86 of the upper hub 5 and grooves 86 of the lower hub 4 are parallel to each other in shape vertically. Therefore, also the struts 6, 6b which pivotally attached to the brackets 48 of the lower hub 4 via pins 49 are at an offset angle relative to the center pole 3a, 3b, meaning that a line running along the top, or inside, of strut 6, 6b and projecting straight from it, would not pass through the center point, or substantially center point, of pole portion 3b or the center point, or substantially center point, of the lower hub 4. The offset angle of ribs 7 and the offset angle of struts 6, 6b are similar, or the same. The offset angle attachment described and depicted serves to create a space for the motor 20 (and housing 19) and allow the parasol fan structure/assembly 99, 100 to close in the smallest diameter possible when in a closed configuration.

[0112] In some embodiments, ridges 88 and ridges 89 are not equal in length. In the embodiment shown (FIGS. 9 and 29), ridges 89 are longer (horizontally) than ridges 88. In the embodiment shown, on the first side of each ridge 88, the first side bordering the shallower side/wall of groove 86, there is a rib 7 pivotally attached to a strut 6a which is attached to an attachable fan device 12, while on the other side of each shorter ridge 88, there is a rib 7 pivotally attached to a strut 6 which is not attached to an attachable fan device 12. Thus, in some embodiments, the presently disclosed parasol fan structure/assembly 99, 100 comprises multiple pairs of ribs 7, each pair comprises one rib 7 which is pivotally attached to a strut 6 which is not attached to an attachable fan device 12 and one rib 7 which is pivotally attached to a strut 6a which is attached to an attachable fan device 12, and there is a bigger space between the respective pairs of ribs 7 than there is between the ribs 7 in a pair. The uneven spacing described and depicted also serves to create space for the motor 20 (and housing 19) and allow the parasol fan structure/assembly 99, 100 to close in the smallest diameter possible when in a closed configuration.

[0113] Referring now to FIG. 10, portion 38A (see FIG. 6) is illustrated depicting the lower hub 4 comprising pulleys 14, the pulleys 14 coupled to rope 11. In some embodiments, the lower hub 4 comprises an aperture 60 for the passage of the rope 11 through the lower hub 4. The lower hub comprises a plurality of brackets 48 comprising pins 49 designed for pivotal attachment to struts 6 and strut portions 6b via opposing openings 45. The lower hub 4 and upper hub 5 have the same number of brackets 48. The lower hub 4 comprises pin 15 used to secure the lower hub 4 in a pre-determined position on pole portion 3b, the position relative to the upper hub 5. The pin 15 is attached to the lower hub 4 by chain 59, and is designed to fit in opening 36 in pole portion 3b. In some embodiments, there is a plurality of openings 36, and each opening 36 defines a pre-determined configuration of the parasol fan structure/assembly 99, 100, for example, an open configuration or a closed configuration. In some embodiments, the presently disclosed parasol fan structure/assembly 99, 100 comprises several pre-determined open configurations and therefore several positions of openings 36. Each pre-determined open configuration defines a degree of the expansion of the ribs 7 with relation to a center pole or pole portion 3b. Each pre-determined open configuration also defines an angle of struts 6a, 6b with relation to a center pole or pole portion 3b and thus the position of the attachable fan device 12 with relation to a user using the parasol fan structure/assembly 99, 100. Thus, a user may configure the parasol fan structure/assembly 99, 100 in a plurality of open configurations, to adjust the position of the attachable fan device 12 and therefore the direction of the air flow produced by the attachable fan device 12 as desired. FIG. 10 features two open configurations as defined by the two openings 36 illustrated. Possible configurations of the parasol fan structure/assembly 99, 100 are further discussed herein.

[0114] FIGS. 11 and 12 depict assembly 61 comprising rib 7, strut 6, and joint 41. Joint 41 is designed to strap rib 7 and pivotally attach it to strut 6 employing pin 64 which goes through opposing openings 63 and 62 on rib 7 and strut 6, respectively. Generally, a pin is interchangeable with any other securing means according to the present disclosure. In some embodiments (not shown), assembly 61 does not comprise joint 41, and strut 6 is pivotally attached to rib 7 via a pin 64 which goes through opposing openings 63 and 62 on rib 7 and strut 6, respectively, thus pivotally securing them together.

[0115] FIGS. 12 and 13 depict assembly 65 comprising rib 7, struts 6a, 6b, attachable fan device 12, and joint 41. Joint 41 is designed to strap rib 7 and pivotally attach it to strut 6a employing pin 64 which goes through opposing openings 63 and 62 on rib 7 and strut 6a, respectively. In some embodiments, rib 7 of assembly 65 further comprises opening 66 usable for the passage of electrical wiring 16 from inside rib 7 to run along, or inside, strut 6a, and then electrically and operably connect to attachable fan device 12. An embodiment of the components of the attachable fan device 12 is depicted. According to the example of FIG. 14, the attachable fan device 12 comprises a housing 19 which partially encases an electric motor 20 comprising a shaft 84 which rotates when the electric motor 20 is powered by electricity. In some embodiments, the attachable fan device 12 further comprises an electric actuator 23 which is electrically connected to the electric motor 20 and operably connected to a biased pin 24 (depicted in FIG. 15). In some embodiments, the attachable fan device 12 further comprises a notched disk 25. The notched disk comprises at least one notch 26 on its perimeter (depicted in FIG. 15), the notch 26 is designed to receive the biased pin 24. In some embodiments, the notched disc 25 further comprises a tubular shaft 27. The tubular shaft 27 is designed to be attached to, and be operably connected to, the shaft 84 of the electric motor 20. The presently disclosed attachable fan device 12 further comprises a fan component, the fan component comprises two fan blades 17 and a center hub 28 therebetween. The center hub 28 is designed to be operably attached to the tubular shaft 27 in such manner that the fan blades 17 are substantially parallel to the at least one notch 26.

[0116] In some embodiments, when the electric motor 20 is powered by electricity, the electric actuator 23 actuates to retract the biased pin 24 from a protruded position in which the biased pin 24 is inserted in the notch 26 to retracted position in which the biased pin 24 is outside the notch 26, thus allowing the notched disk 25 to rotate and in turn rotate the fan blades 17. However, when the electric motor 20 is not powered by electricity, the electric actuator 23 releases the biased pin 24 from the retracted position allowing the biased pin 24 to enter the notch 26, thus preventing the notched disk 25, and in turn the fan blades 17, from rotating. Since, the connection of the fan components 28, 17 to the tubular shat 27 is such that the fan blades 17 are substantially parallel to the at least one notch 26, it means that when the fan blades' rotation ceases, the fan blades 17 are positioned substantially parallel to the notch. In some embodiments, the notched disk 25 comprises a pair of opposing notches 26.

[0117] In some embodiments, the attachable fan device 12 further comprises two opposing parasol attachments 18. In some embodiments, the parasol attachments 18 are tubular and have a first end and a second end. The first end of each parasol attachment 18 is attached to the fan component housing 19 (also referred to herein as housing), and the parasol attachments 18 are substantially parallel to the biased pin 24. In some embodiments, the attachable fan device 12 further comprises a top mounting bracket 67 and a bottom mounting bracket 68. The top mounting bracket 67 and a bottom mounting bracket 68 are designed to hold the actuator 23, and biased pin 24, in between them and in a position parallel to the parasol attachments 18. In some embodiments, the top mounting bracket 67 clips onto the bottom mounting bracket 68, and the bottom mounting bracket 68 is secured to the parasol attachments 18 via a securing means going through overlapping openings 69 and 70. In some embodiments (depicted in FIG. 14), the second end of one parasol attachment 18 attaches directly to strut portion 6a while the second end of the other parasol attachment 18 attaches directly to strut portion 6b. In some embodiments, components of the attachable fan device 12, such as motor 20, actuator 23, biased pin 24, housing 19, top mounting bracket 67, bottom mounting bracket 68, part of the notched disc 25, and/or part or entire parasol attachments 18 are encased by motor housing 21.

[0118] FIG. 15 illustrates an exploded view of another embodiment of the presently disclosed fan device 12. The attachable fan device 12 includes fan components 28, 17 directly, or indirectly, attached to parasol attachments 18. The parasol attachments 18 are configured to attach the fan components 28, 17 to a structure, such as a structure of a parasol or an umbrella. Components of the fan components 28, 17 are operably attached to an electric motor 20 which is partially encased in a housing 19. In some embodiments, the housing 19 comprises a surface comprising opening 71 for the shaft 84 of the electrical motor 20. The housing 19 surface further comprises walls along its perimeter. In some embodiments, the housing 19 further comprises groove 72 designed to fit biased pin 24 in a position parallel to parasol attachments 18. In some embodiments, the housing 19 further yet comprises an opening, proximal to groove 72, the opening designed to allow the electrical connection/wiring of the electrical actuator 23 to the electrical motor 20. The electrical motor 20 is secured to the housing 19 by way of motor housing 21 which encases the motor 20 and other components of the attachable fan device 12. In some embodiments, the parasol attachments 18 include parasol attachment inserts 22 which may be particularly sized and shaped to configure the parasol attachments 18 for attachment to a correspondingly particularly sized and shaped structure, e.g., a strut 6a, 6b with a particular size and shape. An actuator 23 (e.g., electric solenoid actuator 23) is electrically, and operably, connected to the motor 20 and operates a pin (biased pin) 24 that is biased toward a notched disk 25 that contains one or more notches 26 thereon. The notched disk 25 is affixed to the electric motor shaft 84, and in tum is attachable to the center hub 28 which joins the blades 17 of the attachable fan device 12. During an operation of the electric motor 20, the shaft 84 is rotated and the notched disk 25 and the rotatable fan blades 17 also rotate, and the electric actuator 23 actuates to retract the biased pin 24 from a protruded position to a retracted position and to hold the biased pin 24 in the retracted position. When the operation ceases, the electric actuator (e.g., a solenoid actuator) 23 releases the biased pin 24 which enters the protruded position and enters the notch 26 of the notched disk 25, causing the notched disk 25, the shaft 27, and the rotatable fan blades 17 to cease rotation and enter a halted position. The notches 26 of the notched disk 25 are then positioned adjacent, or parallel, to portions of the strut 6a, 6b and fan blades 17 are prevented from rotating beyond a parallel configuration with the portions of the strut 6a, 6b of the parasol fan structure/assembly 99, 100 or umbrella. In this manner, the attachable fan device 12 may be left attached to the parasol fan structure/assembly 99, 100 or umbrella before, during, and after use, and the blades 17 of the attachable fan device 12 do not interfere with and are not damaged by a closing parasol fan structure/assembly 99, 100 or umbrella. This convenience greatly facilitates setup and takedown for staff and other individuals involved with maintenance or use of the assembly.

[0119] In some embodiments, a biased pin 24 may be mechanically biased with a spring, for example, or may be biased as part of a built-in mechanical bias of the actuator 23 that is in effect when the actuator 23 is passive, i.e., not actuated. The biased pin 24 is insertable into a notch 26 of the notched disk 25 and is retractable by an actuator 23, such as an electric actuator 23, for example a solenoid actuator. During operation of the attachable fan device 12 and rotation of the fan blades 17, as occurs as a result of a user switching on the attachable fan device 12, the shaft 27 and the notched disk 25 also rotate, and the actuator 23 actively retracts the biased pin 24 to overcome a bias of the biased pin 24 which enters a retracted position to allow the notched disk 25 to rotate freely. When the operation is concluded, such as when a user switches off the attachable fan device 12, the actuator 23 releases the biased pin 24 which succumbs to its bias and enters a protruded position. The biased pin 24 may contact portions of the notched disk 25 as it rotates. The protruded biased pin 24 enters the notch 26 of the notched disk 25 and stops the notched disk 25 from rotating further which, therefore, causes the shaft 27 and the fan blades 17 to also stop rotating. The fan blades 17 then would be positioned directly over the notches 26, and as the notched disk 25 comes to rest, the notches 26 and the fan blades 17 would be oriented parallel or at least mostly parallel with strut portions 6a, 6b.

[0120] Referring now to FIGS. 16 and 17, the parasol fan assembly 100 is illustrated. The parasol fan assembly 100 generally comprises the presently disclosed parasol fan structure 99 and any type of applicable canopy 2a, 2b. For example, the canopy 2a, 2b may be designed as one continuous piece (which may include various features, such as, aperture/s) or designed as multiple pieces which may have gaps between them. The gaps, or apertures, may serve as vents to allow air flow for the operation of the attachable fan device/s. The parasol fan assembly 100 is depicted in a pre-determined open configuration, for example, a fully open pre-determined configuration in which the canopy 2a, 2b is in the most expanded, horizontal-wise, pre-determined open configuration. Air circulation for the operation of the attachable fan devices 12 is provided by ambient air present all around the parasol fan assembly 100, and, also from above the parasol fan assembly 100 via vent 8 which is basically the gap between canopy 2a and canopy 2b. Vent 8 allows for air circulation from above the fan parasol assembly 100. While one embodiment of vent 8 is depicted, one skilled in the art will appreciate that venting of a parasol canopy can be done in a variety of methods. Some examples, relevant especially to the embodiment according to which the parasol fan assembly's canopy 2a, 2b is one continuous canopy, include aperture/s of any number, size, or shape in the canopy/canopies 2a, 2b. Portion 39A in FIG. 17 is depicted in FIG. 18, illustrating the joint 41 pivotally attaching strut 6a (or 6 for the neighboring rib 7) to rib 7, and an end of joint 41 is inserted into a pocket 73. Pockets 73 are positioned along the outer circumference of canopy 2a, and joints 41 reversibly attached to them keep canopy 2a attached to the parasol fan structure 99. Similarly, pockets 74 are positioned along the outer circumference of canopy 2b and the ends of ribs 7 which are distal from the upper hub 5 are reversibly attached to them, and thus keep canopy 2b attached to the parasol fan structure 99.

[0121] FIGS. 19 and 20 illustrate the parasol fan assembly 100 in a pre-determined open configuration, for example, a pre-determined open configuration in which the canopy 2a, 2b is not in the most expanded, horizontal-wise, pre-determined open configuration. In such open configuration, canopies 2a, 2b are positioned in a narrower angle relative to pole portion 3b, compared to what the angle would be in a fully open pre-determined configuration, for example, the configuration depicted in FIGS. 16 and 17. The presently disclosed parasol fan assembly 100 comprises a plurality of pre-determined open configurations, in some embodiments, three pre-determined open configurations. In each pre-determined open configuration, the position and angle of the attachable fan device/s 12 relative to a user underneath the canopy 2a, 2b is different. Thus, a user can choose an open configuration which directs fanned air in a preferred manner. In each of the pre-determined open configurations of the parasol fan assembly 100, vent 8 supplies air circulation from above the canopy 2a, 2b and thus allows the attachable fan device/s 12 to work efficiently.

[0122] Control unit 13 is depicted in FIGS. 16, 17, 19, and 20. The exemplary control unit 13 includes a body with a plurality of buttons 33 (also referred to herein as switches 33) thereon and a control circuitry 75. The switches 33 and port 32 are operably connected to control circuitry 75 (control circuitry 75 is depicted in FIG. 28) of the control unit 13 for control of the attachable fan device/s 12. The control unit 13, as shown, also includes a charge port 32 to allow a user to charge a personal electronic device, such as a cell phone, tablet, etc. The consumer may experience greater convenience with being able to both charge an electronic device and operate the attachable fan device 12 with the control unit 13.

[0123] FIGS. 21, 22, 25, 26, 27, and 29 illustrate an embodiment of components of the electrical wiring system of the parasol fan structure/assembly 100. The electrical wiring system comprises electrical wiring 16 and electrical connectors 40. According to the example illustrated, electrical wiring 16 enters pole portion 3a and runs upward to connect electrically, and operably, to control circuitry 75 of the control unit 13. Electrical wiring 16 electrically connected to the control circuitry 75 then runs upward inside pole portion 3b and electrically connects to electrical connector 57 of the upper hub's PCB 53. Internal wiring 82 of PCB 53 electrically connects each electrical connector 56 to electrical connector 57. Electrical wiring 16 is electrically connected to electrical connectors 56 and then exits the upper hub 5 via opening 54 and runs inside each rib 7 which is connected to strut portion 6a. Electrical wiring 16 exits rib 7, via opening 66, and runs inside strut portion 6a and electrically, and operably, connects to the attachable fan device motor 20. In some embodiments of the present disclosure, the electrical wiring system comprises additional electrical connectors 40. For example, the electrical wiring 16 which enters pole portion 3a may electrically connect with another electrical wiring 16 enroute to the control circuitry 75. Such electrical connection may be accessible through opening 43 thus allowing easy repairs when needed. Another example is the electrical connection between the electrical wiring 16 which exits the rib 7 via opening 66 and the electrical wiring 16 which run inside strut portion 6a, which in this case also exemplifies having an electrical connection at a relatively accessible location which allows for an easy repair when necessary. In some embodiments according to which the parasol fan assembly 100 comprises a plurality of switches 33 and each switch 33 is operably connected to one attachable fan device 12, electrical wiring 16 from the control unit 13 comprises a plurality of electrical wires, with each electrical wire electrically and operably connected to one switch 33. According to this embodiment, electrical connector 57 comprises a plurality of distinct electrical connectors 40 to match the number of the said electrical wires. In turn, each electrical connector 56 is electrically connected to one of the distinct electrical connectors 40 comprised in electrical connector 57 via internal wiring 82. Electrical wiring 16 running from each electrical connector 56 is operably connected to one attachable fan device 12. This allows a user to operably control a chosen attachable fan device 12. In this embodiment, wherein each switch 33 is operably connected to one attachable fan device 12, the attachable fan device 12 operably connected to a switch 33 is generally positioned above that switch 33. In some other embodiments, one switch 33 is operably connected to a plurality of attachable of fan devices 12 and electrical wiring 16 from the control unit 13 comprises a number of electrical wires which matches the number of switches 33. A person skilled in the art will appreciate that variable electrical wiring is within the scope of the present disclosure.

[0124] Referring now also to FIGS. 23, 24, and 29, in some embodiments the presently disclosed electrical wiring system comprises a safety mechanism to prevent a user from accidentally closing the parasol fan structure assembly 99, 100 when the attachable fan device 12 is still operating. The presently disclosed safety mechanism comprises a Hall sensor 77, a Hall sensor mounting 78, and a magnet 79. In the example illustrated herein, the Hall sensor 77 is positioned inside pole portion 3b and held in place by the Hall sensor mounting 78. The Hall sensor mounting 78 may be attached to the inside of pole portion 3b using any applicable method which will prevent its movement (during use, transport, etc.). Such methods include, but are not limited to, use of any suitable securing means, direct fixture (for example, soldering), adhesive, clips, etc. Electrical wiring 16 is electrically connecting between the Hall sensor 77 and electrical connector 58 on PCB 53. As depicted, the Hall sensor mounting 78 also serves to partially encase the electrical wiring 16 from the Hall sensor 77 as it runs upwards inside pole portion 3b. Internal wiring 83 of PCB 53 electrically connects electrical connector 58 to electrical connector 57, thus electrically powering the Hall sensor 77 when electrical connector 58 is powered by the control circuitry 75 of the control unit 13. As depicted in FIG. 29 the lower hub 4 comprises a magnet 79. In some embodiments, the magnet is positioned inside the lower hub 4 and close to its internal circumference (i.e., proximal to pole portion 3b). Depicted in FIG. 29 are a top cover 80 of the lower hub and a bottom cover 81 of the lower hub, both comprising opening 60 for the passage of rope 11. In some embodiments, the lower hub 4 of the presently disclosed parasol fan assembly 100 is bigger than what is traditionally used in the art. This allows for more space between the center pole 3a, 3b, and the strut 6a, 6b which comprises the attachable fan device. The dimension of the lower hub 4 of the present disclosure allowed the creation of opening 60. Rope 11 passing through opening 60 instead of to the side of opening 60 allows a user to pull or release the rope 11 vertically, thus avoiding the rope 11 getting caught, or entangled, on a moving blade 17, or otherwise any of the attachable fan device/s 12 parts. When the Hall sensor 77 is electrically powered and proximal to the magnet 79, it allows electrical connector 57 to electrically power electrical connectors 56, and in turn power the attachable fan devices 12. When the Hall sensor 77 is not proximal to the magnet 79, it will turn off electrical power to electrical connector 57, and not allow, or cease, the operation of the attachable fan devices 12. Hall sensor 77 is generally positioned inside pole portion 3b such that it overlaps with the lower hub 4 position when the parasol fan structure/assembly 99, 100 is in a pre-determined open configuration/s, generally allowing the operation of the attachable fan device/s 12 only in these pre-determined open configuration/s. This prevents an accidental operation of the attachable fan device/s 12 when the parasol fan structure/assembly 99, 100 is in a closed, or partially closed configuration, thus preventing damage to the attachable fan device/s 12 or any other part/s of the parasol fan structure/assembly 99, 100.

[0125] In some embodiments, the Hall sensor 77 shuts off the electrical circuitry of electrical connector 57 when magnet 79 and the Hall sensor 77 do not overlap. In some other embodiments, Hall sensor 77 shuts of the electrical circuitry of electrical connector 57 when magnet 79 and the Hall sensor 77 have a certain distance between them. In some embodiments, the distance is in a range of about 0.5-30 centimeters. According to some other embodiments, the distance is in a range of about 1-15 centimeters. In some other embodiments, the distance is in a range of 3-10 centimeters. In yet some other embodiments, the distance is about 3, 4, 5, 6, 7, 8, 9, or 10 centimeters.

[0126] FIGS. 30-33 schematically depict the electrical wiring system including the position of the magnet 79 relative to Hall sensor 77 when the parasol fan structure/assembly 99, 100 is in an open, or partially closed, configuration. FIG. 30 depicts the parasol fan structure/assembly 99, 100 in a first pre-determined open configuration according to which the lower hub 4 is secured in the highest pre-determined position along pole portion 3b. In the first pre-determined open configuration exemplified, the magnet 79 partially overlaps with Hall sensor 77, and Hall sensor 77 allows the operation of the attachable fan device 12. FIG. 31 depicts the parasol fan structure/assembly 99, 100 in a second pre-determined open configuration according to which the lower hub 4 is secured in a middle pre-determined position along pole portion 3b. In the second pre-determined open configuration exemplified, the magnet 79 fully overlaps with Hall sensor 77, and Hall sensor 77 allows the operation of the attachable fan device 12. FIG. 32 depicts the parasol fan structure/assembly 99, 100 in a third pre-determined open configuration according to which the lower hub 4 is secured in the lowest pre-determined position along pole portion 3b. In the third pre-determined open configuration exemplified, the magnet 79 again partially overlaps with Hall sensor 77, and Hall sensor 77 allows the operation of the attachable fan device 12.

[0127] FIG. 33 depicts the parasol fan structure/assembly 99, 100 in a partially closed configuration. This will happen, for example, when a user starts to close the parasol fan assembly 100, sliding the lower hub 4 downwards along pole portion 3b, perhaps forgetting to shut off the operation of the attachable fan device 12. In the partially closed configuration exemplified, the magnet 79 no longer overlaps with Hall sensor 77, and the distance between the magnet 79 and Hall sensor 77 is such that the Hall sensor 77 shuts off the circuitry and ceases the operation of the attachable fan device 12. As the operation of the attachable fan device 12 ceases the blades 17 come to a stop in a position parallel to strut portions 6a and 6b.

[0128] Finally, referring to FIG. 34, the presently disclosed parasol fan structure 99 is depicted in a closed configuration and the lower hub 4 is in a position proximal control unit 13. Ribs 7 are substantially parallel to pole portions 3a, 3b, and the fan blades 17 are parallel to struts 6a, 6b and therefore are not damaged in the closed configuration, and do not damage any of the parasol fan structure/assembly 99, 100 parts.

[0129] In some embodiments, the presently disclosed parasol fan structure/assembly 99, 100 may include wired power delivery and wired control, wired power delivery and wireless control, a local power source in use with the attachable fan device 12 and wireless control that is integral with the control unit 13, or a local power source in use with the attachable fan device 12 and wireless control that is distinct from the control unit 13.

[0130] Both delivery of power and control of the attachable fan device 12 may be provided through electrical wiring 16, as shown herein. In this embodiment, electrical wiring 16 connects an AC source to the control unit 13 and also connects the control unit 13 to the attachable fan device 12 for delivery of power to the attachable fan device 12. The control unit 13 may be operated by pressing buttons or operating dials or switches thereon, which in tum modulates control circuitry 31 to control the attachable fan device 12. In some embodiments, the control circuitry 31 may be structurally associated with or otherwise integral with the control unit 13 and may be operably connected to buttons or switches of the control unit 13 for operation. In this manner, the user may operate the attachable fan device 12 with the control unit 13.

[0131] In embodiments wherein power is delivered to the attachable fan device via electrical wiring 16 from the control unit 13, control of the fan device 12 may be achieved with a wireless connection (not shown). In various embodiments and possibly independent of how power is delivered to the attachable fan device 12, the control circuitry 31 may be structurally associated with or integral with the control unit 13, or, alternatively, may be structurally separate from, separable, or distinct from the control unit 13.

[0132] In embodiments with a wireless connection configured for control of the attachable fan device 12, the control unit 13 may be configured to constantly deliver power to the attachable fan device 12 and control of the use of the power to operate the attachable fan device 12 may be determined with a local control circuit of the attachable fan device 12 that may be operably connected to a wireless receiver that is configured to receive control signals from a wireless transmitter that is operably connected to the control circuitry 31, whether the control circuitry 75 is integral with the control unit 13 or is separate from the control unit 13.

[0133] In any embodiment in which there is a wireless connection, control signals may be sent and received over the wireless connection using any suitable wireless communication protocol, including but not limited to Bluetooth, WiFi, infrared transmission, etc. When a start signal is received to initiate the attachable fan device 12 to turn on and begin operating, the local control circuit of the attachable fan device 12 may close to cause power to be delivered to the motor and the electric actuator of the attachable fan device 12. When a stop signal is received to initiate the attachable fan device to turn off and stop operating, the local control circuit of the attachable fan device 12 may open to cause power to no longer be delivered to the motor and the electric actuator of the attachable fan device 12, which causes the fan blades 17 to stop rotating and become aligned with the strut 6a, 6b of the parasol, as disclosed herein.

[0134] In at least some embodiments, the electrical wiring 16 may be used to deliver power from an AC source to the control unit 13, which may drive control circuitry 75 and may be a charge source for recharging a local power source of the attachable fan device 12. The local power source may be a battery or a plurality of batteries, such as rechargeable batteries, e.g., rechargeable lithium-ion batteries. In instances wherein a rechargeable battery is used, the control unit 13 may include ports (e.g., dedicated, or multi-purpose ports) configured for recharging the rechargeable batteries when not in use. Similarly, if a wireless controller incorporates control circuitry, the wireless controller may need to be recharged, and the control unit 13 may include ports (e.g., dedicated, or multi-purpose ports) for this purpose.

[0135] Next, FIG. 35 shows the skeletal supporting structure for another patio umbrella 200. A vertical pole 216 is held in upright position by placing the bottom pole end into a base 214. A canopy is associated with multiple ribs 240, 242, generally six to eight such ribs, that are moved in the direction of arrows 246 to variously place the patio umbrella 200 into open configuration or closed configuration. In the open configuration, the canopy (see e.g., panels 2a and 2b in FIG. 19) attached to the ribs 240, 242 provides sun shading and the ribs 240, 242 are splayed outwardly from the vertical pole 216. In the closed configuration, the canopy is folded and the ribs 240, 242 are brought closer to the vertical pole 216 that supports the canopy and associated ribs 240, 242.

[0136] Collar connectors 260 join the ribs 240, 242 to first ends 256 of respective struts or stretchers 250, 252. The opposite ends of the stretchers 250, 252 are pivotably connected to a lower hub 230 that encircles the vertical pole 216. The lower hub 230 may be raised or lowered along the vertical pole 216 by the rotation of crank arm 226 of the crank 224. Once raised to a desired vertical position along the vertical pole 216, the lower hub 230 may be secured to the pole additionally by removable pin 234.

[0137] As the lower hub 230 translates upwardly along a portion of the length of the vertical pole 216, the struts or stretchers 250, 252 pivot radially outwardly from the lower hub 230 and push the ribs 240, 242 upwardly to raise the patio umbrella canopy to the open orientation. As the lower hub 230 translates downwardly along a portion of the length of the vertical pole 216, the struts or stretchers 250, 252 pivot inwardly toward the vertical pole 216 and pull the ribs 240, 242 downwardly to lower the patio umbrella canopy to the closed orientation.

[0138] An attachable fan device 270 with rotating blades 272 is attached to the first stretcher 250. The fan blades 272 have blade tips 274. The fan blades 272 rotate to generate air turbulence. In the embodiment shown in FIGS. 35-42, the attachable fan device 270 has a fan housing 276 defining a recess or channel 278 in a housing surface opposite from the blade shaft.

[0139] A retractable fan guard is formed by a first cowling 280, a second cowling 300, a fixed part 284 depending from the first cowling 280, a sliding or movable part 304 depending from the second cowling 300 and a cord 320. The first cowling 280 and the second cowling 300 are attached to the first strut or stretcher 250, arranged on opposite sides of the attachable fan device 270 and spaced a distance from the fan blade tips 274 or the extent of length of the fan blades 272. The first cowling 280 has a curved deflector 282 with a convexly curved surface thereof directed toward the attachable fan device 270. The second cowling 300 has a curved deflector 302 with a convexly curved surface thereof directed toward the attachable fan device 270. The deflectors 282, 302 are arranged above an upper surface of the stretcher 250. Together, the first cowling 280 and second cowling 300 redirect a portion of the air flow generated by the rotating fan blades 272 downwardly away from the umbrella canopy, around the fan housing 276 and toward persons seated or standing below the canopy of the patio umbrella 200 when in the open configuration.

[0140] The first cowling 280 is secured around the first strut or stretcher 250. A fixed part 284 depends from the first cowling 280 and is arranged below a bottom surface of the stretcher 250. The fixed part 284 defines an internal channel 286 configured to receive cord 320. The cord 320 is threaded through the internal channel 286 from the front end 292 of the fixed part to the rear end 294 of the fixed part. The cord 320 is movable in an axial direction of the cord through the internal channel 286. A first pair of movable arms 288 project from side surfaces of the fixed part 284 at or near the front end 292 of the fixed part 284. The movable arms 288 each define an opening suitable to engage the end of one flexible rod 330, 332 (see FIG. 39). A second pair of movable arms 290 project from side surfaces of the fixed part 284 at or near the rear end 294 of the fixed part 284. The movable arms 290 each define an opening suitable to engage the end of one flexible rod 334, 336 (see FIG. 39).

[0141] The second cowling 300 is secured around the first strut or stretcher 250. A sliding or movable part 304 depends from the second cowling 300 and is arranged below the bottom surface of the stretcher 250. The movable part has a front end 312 and a rear end 314 opposite from the front end 312. A connection 316 for the cord 320 is provided at the front end 312. A first pair of movable arms 308 project from side surfaces of the sliding or movable part 304 at or near the front end 312 of the sliding or movable part 304. The movable arms 308 each define an opening suitable to engage the end of one flexible rod 330, 332 (see FIG. 39). A second pair of movable arms 310 project from side surfaces of the sliding or movable part 304 at or near the rear end 314 of the sliding or movable part 304. The movable arms 310 each define an opening suitable to engage the end of one flexible rod 334, 336 (see FIG. 39).

[0142] The flexible rods 330, 332, 334 and 336 may comprise fiberglass. The flexible rods 330, 332, 334 and 336 are straight rods that are bendable to bow or curve when a tensile pushing force is applied axially along the rod length.

[0143] The cord 320 has an end 322 that is attached to the front end 312 of the sliding part (or movable part) 304, and the opposite end 324 of the cord 320 is connected to the upper rib 240. As the rib 240 is urged or pushed by stretcher 250 away from the pole 216 into the open configuration of the patio umbrella, the cord 320 is in turn pulled taut. As the cord 320 is pulled, the sliding part 304 is moved in a direction toward the fixed part 284. Such movement of the sliding part 304 pushes on the flexible rods 330, 332, 334 and 336, causing the rods to bow or curve to create a fan guard under the stretcher 250 and below the housing 276 of the fan 270. Such fan guard is retractable because the flexible rods 330, 332, 334 and 336 are not permanently bowed, but will revert to straightened condition as the tension on cord 320 is released, and the sliding or movable part 304 returns to its initial position spaced apart more from the fixed part 284. The tension on cord 320 is released upon retracting the first stretcher 250 from the umbrella open orientation to the umbrella closed orientation, and causing the first rib 240 to move downwardly. Arrow

[0144] The first cowling 280 and second cowling 300 that are arranged to each side of the attachable fan device 270 and fan blades 272 have multiple functions. The cowlings 280, 300 not only serve to redirect air flow, but also form part of the fan guard to protect users and consumers from the rotating blades 272. The cowlings 280, 300 deter the pull rope 11 that raises and lowers the umbrella canopy 212 from being caught or entangling in the fan blades 272. The cowlings 280, 300 deter the cord 320 that moves the sliding or moving part 304 from entanglement with the fan blades 272. Moreover, the cowlings 280, 300 also protect the fan 270 from damage when the patio umbrella is closed. When folded, the cowlings 280, 300 face inwards towards the center pole 216. Exterior pull cords or ropes 11 run parallel to the center pole 216. Each cowling 280, 300 acts as an end cap to the fan blades 272, preventing the pull cords or rope 11 from inadvertently hooking around a fan blade 272 and causing damage the next time the umbrella 200 is opened. The shape of the cowlings 280, 300 allows air from near the center pole 216 and outer edges to move up and around the fan 270. Without the cowlings 280, 300, the fan's downward air force is more spread out or dispersed. The air pushing down prevents air circulation. This results in an undesirable pulsing effect of the downward air from the fan 270 because of lower air pressure above the fan 270.

[0145] The first cowling 280 and second cowling 300 have base portions arranged below the first stretcher 250 to which the respective fixed part 284 and sliding or movable part 304 are secured. The base portions may be of a suitable shape and thickness to accommodate attachment of other patio umbrella accessories, including but not limited to, lighting fixtures, heating elements, sound speakers, decorations or expandable reflective material for cold weather months.

[0146] In an advantageous embodiment, the cowlings 280, 300 and the fixed part 284 and the movable or sliding part 304 are made of ABS injection molded plastic. In an advantageous embodiment, the flexible rods 330, 332, 334, 336 are made of fiberglass.

[0147] In an advantageous embodiment, the cord 320 is formed of paracord or is a nylon rope with a woven cover.

[0148] The fan devices 12, 270 may be deployed also with a cantilevered umbrella 400 as shown in FIG. 43 or with a roman cantilevered umbrella as shown in FIGS. 44-46. Referring first to the cantilevered umbrella 400 in FIG. 43, the canopy 402 is not centered with the vertical support pole 403a, but is offset from center. A cantilever pole section 403b extends at an angle away from the vertical support pole section 403a. The cantilever angle may be adjusted by unlocking and rotating a handle 426 of an angular adjustment assembly 424 that houses a movable joint within a case of the assembly 424. The top end of cantilever pole section 403b is joined to upper hub 5.

[0149] The canopy 402 may be vented, meaning that the canopy is formed of multiple panels of material, such as canvas, leaving a gap or vent between certain adjacent panels. Vented canopies are advantageous when fan devices 12 are deployed on the umbrella 400.

[0150] The tilt angle and height of the canopy 402 may be adjusted by unlocking the handle 426 and rotating to change the angle of the cantilevered supporting pole section 403b in respect of the vertical supporting pole section 403a.

[0151] Ribs 7 extend outwardly from upper hub 5 of the cantilevered umbrella 400. The ribs 7 engage with the canopy 402. The ends of the ribs 7 held in the upper hub 5 are held for rotation so that they may be urged upwardly to open the canopy 402 and downwardly to close the canopy 402.

[0152] A tubular collar 406 depends downwardly from the upper hub 5 and one end of a telescoping pole 408 is inserted therein. The opposite end of the telescoping pole 408 is joined to a lower hub 4. The telescoping pole 408 may be moved axially within the tubular collar 406. Struts 6 are joined at one end to the lower hub 4 and at their other end to a respective rib 7 with a joint 41. The joints 41 slidably engage the ribs 7. As the telescoping pole 408 is moved upwardly, the struts 6 push the ribs 7 upwardly so that the outer ends of the ribs extend farther from the tubular collar 406 to open the canopy 402. As the telescoping pole 408 is moved downwardly, the struts 6 draw the ribs 7 downwardly so that the outer ends of the ribs are drawn downwardly toward the tubular collar 406 to close the canopy 402.

[0153] In this embodiment of the cantilevered umbrella 400, a hub cord 410 is joined to the lower hub 404 or to the telescoping pole 408 at one end. The hub cord 410 is coiled around a reel 428 associated with the handle 426 at its opposite end. The hub cord 410 extends through the collar 406 and through the upper hub 5 and through the cantilevered supporting pole section 403b. A crank arm 430 may be provided to turn the reel 428 to play out a portion of the hub cord 410 from the reel 428 when closing the umbrella 400. As the hub cord 410 is unrolled from the reel, the lower hub 404 drops downwardly away from the upper hub 5, and the struts 6 pull the ribs 7 downwardly about the collar 406 depending from the upper hub 5. The struts 6 and ribs 7 are thus retracted from the open configuration to the closed configuration. To raise the canopy 402, the hub cord 410 is pulled and more of the cord length is wrapped about the reel 428 thereby drawing the lower hub 404 upwardly so that the telescoping pole 408 engages with the collar 406 depending from the upper hub 5. The upward movement of the lower hub 404 causes the struts 6 to push the ribs 7 upwardly to raise the canopy 402, placing the umbrella 400 into the open configuration as shown in FIG. 43.

[0154] In the embodiment shown in FIG. 43, two fan units 12 are joined to respective struts 6. Power cables or electrical connections 416 run up through the post sections 403a, 403b and through the ribs 7 to a harness at the upper hub 5. An electrical connector wire connects the harness to a control box 413 on the offset vertical pole section 403a. The control box 413 may include a control board, optionally with a receiver for a remote control, one or more USB charge ports 432, an associated printed circuit board (PCB) and switches 433 or other activation means for activating the fan units 12. If a remote control is provided, the remote may include selections to activate the fans and control fan speed. An AC/DC power converter may be provided on or in the supporting pole 403a, and an AC power cord may be operably connected.

[0155] The fan units 12 may include retractable fan guards with cowlings 280, 300 and flexible rods 330, 332, 334 and 336 to deflect or direct air from the fan units 12 toward persons under the canopy 402, and to protect such persons from contacting the rotating fan blades 17 of the fan units 12.

[0156] Referring next to FIGS. 44-46, another type of cantilevered umbrella 500 commonly referred to as a roman style cantilever has a vertical support post 503 that has a fitting 594 at the top to which a first end of a top arm 596 is hingedly joined. A second end of the top arm 596 is hingedly joined to a fitting 598 that is attached at a middle section of a cantilever arm 590. The cantilever arm 590 is held at one end by a cantilever angle lock 524 and at its opposite end by an elbow fitting 592. The elbow fitting 592 is joined to the top hub 5 of the umbrella supporting structure.

[0157] The canopy 502 (shown in phantom line in FIG. 44) may be vented, meaning that the canopy is formed of multiple panels of material, such as canvas, leaving a gap or vent between certain adjacent panels. Vented canopies are advantageous when fan devices 12 are deployed on the umbrella 500.

[0158] The tilt angle and height of the canopy 502 may be adjusted by unlocking the handle 526 and rotating to change the angle of the cantilever arm 590 in respect of the vertical supporting pole 503. The cantilever angle lock 524 may be moved upwardly and downwardly along the pole 503 and then locked in a desired height and angle by activating the lock with handle 526.

[0159] Ribs 7 extend outwardly from upper hub 5 of the cantilevered umbrella 500. The ribs 7 engage with the canopy 502. The ends of the ribs 7 held in the upper hub 5 are held for rotation so that they may be urged upwardly to open the canopy 502 and downwardly to close the canopy 502.

[0160] A tubular collar 506 depends downwardly from the upper hub 5. A lower hub 504 seats in or abuts the lower portion of the tubular collar 506 when the canopy 502 is in an opened configuration. Struts 6 are joined at one end to the lower hub 4 and at their other end to a respective rib 7 with a joint 41. The joints 41 slidably engage the ribs 7. As the lower hub 504 is moved upwardly, the struts 6 push the ribs 7 upwardly so that the outer ends of the ribs extend farther from the tubular collar 506 to open the canopy 502. As the lower hub 504 is moved downwardly, the struts 6 draw the ribs 7 downwardly so that the outer ends of the ribs are drawn downwardly toward the tubular collar 506 to close the canopy 502.

[0161] In this embodiment of the cantilevered umbrella 500, a hub cord 510 is joined to the lower hub 504 at one end. The hub cord 510 is coiled around a reel associated with the handle 526 at its opposite end. The hub cord 510 extends through the tubular collar 506 and through the upper hub 5 and through the cantilever arm 590 to the reel within the handle 526. A crank arm 530 may be provided to turn the reel to play out a portion of the hub cord 510 from the reel when closing the umbrella 500. As the hub cord 510 is unrolled from the reel, the lower hub 504 drops downwardly away from the upper hub 5, and the struts 6 pull the ribs 7 downwardly about the collar 506 depending from the upper hub 5. The struts 6 and ribs 7 are thus retracted from the open configuration to the closed configuration. See FIGS. 45 and 46. To raise the canopy 502, the hub cord 510 is pulled and more of the cord length is wrapped about the reel thereby drawing the lower hub 504 upwardly so that lower hub 504 engages with or abuts the collar 506 depending from the upper hub 5. The upward movement of the lower hub 504 causes the struts 6 to push the ribs 7 upwardly to raise the canopy 502, placing the umbrella 500 into the open configuration as shown in FIG. 44.

[0162] In the embodiment shown in FIGS. 44-46, two fan units 12 are joined to respective struts 6. Power cables or electrical connections 516 run up through the post 503, the top arm 596 and the cantilever arm 590, and then to a harness at the upper hub 5. From the harness at the upper hub 5 the wires extend to individual fan devices 12 through the respective ribs 7. An electrical connector wire connects the harness to a control box 513 on the vertical pole 503. The control box 513 may include a control board, optionally with a receiver for a remote control 550, one or more USB charge ports 532, an associated printed circuit board (PCB) and one or more switches 533 or other activation means for activating the fan units 12. If a remote control 550 is provided as in FIG. 44, the remote 550 may include selections to activate the fan units 12 and control fan speed. An AC/DC power converter 560 may be provided on or in the vertical pole 503, and an AC power cord 562 may be operably connected.

[0163] A mounting 578 may be disposed within the tubular collar 506 for a Hall sensor 577. The Hall sensor 577 detects position of a magnet 579 disposed on or inside the lower hub 504. As the lower hub 504 is lowered when the hub cord 510 is unwound (extended) as the umbrella is being closed, the movement of the lower hub 504 in respect of the mounting 578 is detected by the Hall sensor 577. Upon detecting such movement, the Hall sensor 577 transmits a signal to the control box or PCB therein to deactivate the fan units 12. The fan blades 17 will stop rotating for user safety and to better facilitate closing the umbrella without catching the hub cord 510 or any other umbrella support structure.

[0164] Optionally, and advantageously, the fan units 12 may include retractable fan guards with cowlings 280, 300 and flexible rods 330, 332, 334 and 336 to deflect or direct air from the fan units 12 toward persons under the canopy 502, and to protect such persons from contacting the rotating fan blades 17 of the fan units 12.

[0165] As shown in FIGS. 45 and 46, the cantilevered umbrella 500 may be retracted and placed into closed configuration while the fan units 12, with or without retractable fan guards (fan guards not shown in FIGS. 45 and 46), remain attached to the struts 6. The fan units 12 are attached to the struts 6 with the fan blades 17 of each respective fan unit 12 rotating in a plane above the respective strut 6 to protect persons from contacting the fan blades 17 when the umbrella 500 is open as shown in FIG. 44. When the Hall sensor 577 detects movement of the magnet 578 as the lower hub 504 moves away from the tubular collar 506, the fan blades 17 cease rotation as the umbrella 500 is being folded into the closed configuration. See FIGS. 45 and 46.
