DETAILED DESCRIPTION OF THE DRAWINGS
(21) FIGS. 1A to 2 show the present device 10 when the device is operating as an aquatic bodyboard. FIG. 3 shows the device mid-way between the conversion from an aquatic bodyboard to a beach chair. FIG. 4 shows the final position of the device 10 when being used as a beach chair. The present device 10 may be converted back and forth between its flat planar bodyboard position (FIGS. 1A to 2) and its angled chair position (FIG. 4), and back and forth again and again, whenever it is desired to do so.
(22) As seen in the attached FIGS. 1A to 5, combination bodyboard and chair device 10 comprises a bodyboard front panel portion 20 and a bodyboard rear panel portion 22 pivotally connected together at pivot point 21. In preferred aspects, bodyboard panel portions 20 and 22 may be made from extruded polypropylene, or other suitable lightweight, sturdy but buoyant material.
(23) A folding mechanism 30 is configured to move the front and rear panel portions 20 and 22 between a flat bodyboard position of FIGS. 1 and 2 and the angled chair position of FIG. 4. As seen in FIGS. 1A to 2, the front and rear bodyboard panel portions 20 and 22 are co-planar when the system is in the flat bodyboard position, and angled to one another when the system is in the angled chair position. FIG. 3 shows a mid-way position when the device 10 is being converted from a bodyboard into a beach chair. FIG. 4 shows the device 10 after it has been fully converted into a beach chair.
(24) Folding mechanism 30 comprises a pivoting connection at pivot point 21 between the bodyboard front and rear portions 20 and 22. As seen in FIG. 4, the folding mechanism 30 of chair 10 includes a pair of armrests 40 and leg members 50. As can also be seen the four leg members 50 can be connected together in pairs to form a front leg 54 and a back leg 52 for the chair.
(25) In accordance with this preferred embodiment of the present system, the armrests 40 are received into armrest openings 41 in one or the other of the front or rear panel portions 22 when the system is in the flat bodyboard position. FIG. 5 shows further details with some of the structural components removed for clarity of illustration. Specifically, armrest openings 41 are seen in the top of rear panel portion 22 (Note only a part of rear panel portion 22 is illustrated in FIG. 5). Armrest openings 41 are positioned at the side edges of rear panel 22. It is to be understood that in various embodiments, armrest openings 41 may be disposed in one or the other or both of the front or rear panel portions 20 or 22.
(26) Similarly, the leg members 50 are received into leg openings 51 at side edges of one or the other of the front or rear panel portions 20 and 22 when the system is in the flat bodyboard position. As seen in FIG. 5, a leg member 50 at the front of the chair may rotate together with an armrest support member 43, and be formed from the same piece of material. Similarly, another leg member 50 at the back of the chair may rotate together with an armrest support member 42, and be formed from the same piece of material. In alternate embodiments, armrest rear support member 42 may be rotatable with respect to back leg member 50 around pivot point 49.
(27) In preferred embodiments, folding mechanism 30 thus comprises: a pair of armrests 40, four armrest support members 42 and 43, and four leg members 50. As seen in FIG. 3, the four armrest support members 42 and 43 and the four leg members 50 are pivotally mounted to the bodyboard rear panel portion.
(28) As seen in FIG. 2, front leg 54 may be received into an opening 54 and back leg 52 may be received into an opening 53, with openings 53 and 54 spanning across the bottom of the device 10, for example across the bottom of rear panel 22. In its collapsed bodyboard position (FIGS. 1A to 2), the armrests 40, armrest supports 42 and 43, leg members 50 and legs 52 and 54 are all received into cutaway portions of the bodyboard panels 20 and 22.
(29) As best seen in FIGS. 4 and 5, front leg 54 may be angled out forwardly and the back leg 52 may be angled out backwardly when the system is in the angled chair position. This position gives the chair stability and prevents it from falling over.
(30) As seen in FIGS. 3, 4 and 5, armrests 40 may be pivotally connected to bodyboard front portion 20 at pivot point 45 and to armrest support member 43 at pivot point 47. Armrests 40 and their associated armrest support members 42 and 43 are all received into the plane of the bodyboard when the device is in its collapsed bodyboard position. As best seen in FIGS. 4 and 5, armrest supports 42 are preferably rotated into a locked position under armrest 40. Specifically, the top ends of armrest supports 42 may have a pin that is rotated into a latched locked position at point 49 under armrest 40. As such, each rear armrest support members 42 may either move together with leg member 50 and be made out of the same block of material, or may be members 42 and 50 may be made of different blocks of material, both pivoting around pivot point 49, all keeping within the scope of the present invention. An advantage of having members 42 moveable with respect to members 50 is that members 42 can be rotated forwardly into the locked position seen in FIG. 5, without moving corresponding leg member 50.
(31) In optional embodiments, a locking mechanism 60 is provided to secure at least one or both of the armrests 40 or armrest support members 42 or leg members 50 to the rear panel portion 22 when the system is in the flat bodyboard position. Locking mechanism 60 preferably comprises a button and latch mechanism on one or both sides of the device that requires the user to depress the button to release either or both of the armrests 40 or leg members 50 from the panel portion 22 of the device. Locking mechanism 60 prevents the armrests 40 and leg members 50 from accidently deploying while device 10 is being used as an aquatic bodyboard.
(32) FIGS. 6 and 7 set forth two alternate embodiments of the present system, both encompassed by the presently claimed invention, as follows. FIG. 6 shows bodyboard front and rear portions 20 and 22 connected together at pivot point 21. In accordance with this embodiment, no armrests are provided. Instead, panel portions 20 and 22 are shaped such that they rotate to the angle and position shown. A locking mechanism (not shown) can be used to hold front panel portion 20 in the illustrated angled chair position shown (or, alternately locked in the flat bodyboard position) such that it operates as the user's back support when the device is in its chair orientation as shown. In addition, foldable legs 52 and 54 can be rotated up into openings in the bottom side of rear panel portion 22 when the device is in its flat bodyboard position.
(33) The optional embodiment shown in FIG. 7 is similar to FIG. 6, except that rear body portion 22 rests on the ground and a single leg 57 is used instead. Leg 57 is received into an opening in the bottom of panel portion 20 and optionally panel portion 22 as well (depending upon the exact length and positioning of leg 57 on front panel portion 20). A locking system (not shown) is used to hold bodyboard panel portions 20 and 22 in their flat orientation when the device is being used as an aquatic bodyboard.
(34) FIGS. 8 to 9B illustrate a fourth embodiment of the present system. In this embodiment, leg member 50 also extends upwardly and rotates into a locked position under armrest 40, thereby supporting armrest 40. As seen in FIG. 9A, therefore, rear leg 52 points in an opposite (i.e.: forward) direction as compared to the illustration of the embodiment of FIG. 2. FIG. 8 illustrates the chair position for this embodiment of the invention. FIG. 9A illustrates the bodyboard position and FIG. 9B illustrates the mi-way position, showing the rotation of the leg members 50 forming legs 52 and 54.
(35) Lastly, FIGS. 10 to 18 illustrate a fourth embodiment of the present system. In this embodiment, the front and back legs 54 and 52 are both positioned at the rear end of the bodyboard when the device is in the bodyboard position of FIG. 10. As seen in FIG. 11, the user first extends leg member 50A (two leg members 50A are connected together to form rear leg 54). Next, as seen in FIG. 12, leg members 50A and 50B are rotated together to deploy armrests 40). Leg members 50B are connected together to form front leg 54, and leg members 50A and 50B sit parallel next to one another in the bodyboard position of FIG. 11. Next, as seen in FIG. 13, leg members 50A are rotated backwardly such that leg 52 is now positioned behind the chair, and the chair is now ready for use.
(36) FIGS. 15 to 18 show further details of the positioning system 30 of the embodiment of FIGS. 10 to 14. As seen in these figures, leg members 50A and 50B are connected together at fastener 70. Fastener 70 has two raised portions 72 which are received into slots in leg member 50A. Fastener 70 also has a pin 74 which is received into a notched underside portion 46 in armrest 40. Fastener 70 is rotatable within an aperture in leg member 50B. As such, leg members 50A and 50B can be rotated with respect to one another around fastener 70 during deployment of the legs. In addition, fastener 70 can be moved to various positions within notched underside portion 46 in armrest 40, such that the angle of the back of the chair can be adjusted (i.e.: the angle of portions 22 and 24 with respect to one another can be adjusted by moving pin 74).
(37) It is to be understood that the present invention encompasses those embodiments that would be obvious modifications to one skilled in the art.
