DETAILED DESCRIPTION

(20) Referring now to the drawings and in particular to FIGS. 1 through 4C, a cleaning device 10 according to the present disclosure is shown, which is configured to allow for cleaning of hard to reach locations and has a selectively flexible or rigid handle.

(21) Cleaning device 10 is shown by way of example as having a cleaning implement 12 illustrated as a brush, but of course it is contemplated by the present disclosure for device 10 to find use with other cleaning implements such as, but not limited to, a duster, a scrubber, a scraper, a squeegee, an applicator, mop, and any combinations thereof. Device 10 can include one or more features such as, but not limited to, a handle or pole 14 (hereinafter “handle”) and a telescoping device 16, which allows the handle to be telescope between extended and retracted positions in a known manner.

(22) Advantageously, device 10 includes a flexible neck 18. For example, neck 18 can be as disclosed in Applicant's U.S. application Ser. No. 14/791,531, which is incorporated by reference herein—where the neck provides a first level of flexion in a first orientation as shown in FIG. 2A, but a second, lower level of flexion in a second orientation shown in FIG. 2B.

(23) As used herein, the term “orientation” shall mean a degree of rotation about a longitudinal axis of handle 14. In this manner, the user can use device 10 in the first orientation to allow the cleaning device to flex into hard to reach places and can use the same device in the second orientation to apply a higher level of cleaning force.

(24) However, it is also contemplated by the present disclosure for the neck to provide equal levels of flexion in all orientations as shown in device 10′ of FIGS. 3A-3C. Here, device 10′ includes neck 18 that is particularly configured to be rotated while in a flexed position, allowing the neck to act as a universal joint during rotation. It should be noted that device 10′ of FIGS. 3A-3C is shown without telescoping device 16. It should also be noted that device 10′ is configured with neck 18 completely encased in elastomeric material as discussed in more detail below.

(25) In this embodiment, device 10′ provides the same level of flexion regardless of how the user orients cleaning implement 12 with respect to the surface being cleaned.

(26) The terms “rigid”, “inflexible”, “flexible”, and the like are obviously terms of degree and are used herein to describe the general properties neck 18.

(27) Strictly speaking, neck 18 allows flexion, upon application of sufficient force, in the first orientation, but resists flexion in the second orientation. Neck 18 can have a stiffness ratio of flexion in the first orientation to flexion the second orientation of between 2:1 to 100:1, more preferably between 5:1 and 50:1, with about 10:1 being most preferred.

(28) Neck 18 is, preferably, molded as a single unitary member with upper region 20, a lower region 22, and a rib 24 formed together—with an elastomeric member 26 molded over at least portions of the rib—best seen in FIG. 4B. In some embodiments, elastomeric member 26 is molded over the entire rib 24 so that the rib is encased by the elastomeric member as in FIGS. 3A-3C.

(29) It is noted that rib 24 in the embodiment of FIGS. 1, 2A-2B, and 4A-4C has a rectangular cross section that allows for the first and second levels of flexion depending on the orientation, while rib 24 in the embodiment of FIGS. 3A-3B has a circular cross section that allows for equal levels of flexion regardless of the orientation.

(30) Elastomeric member 26 is, preferably, over molded onto rib 24 during manufacture using a material such as, but not limited to a thermoplastic elastomer (TPE) or thermoplastic rubber (TPR). Of course, it is contemplated by the present disclosure for elastomeric member 26 to be secured to neck 18 in any desired manner such as, but not limited to, mechanical fastening, thermal fastening, adhesive fastening, and any combinations thereof.

(31) Advantageously, elastomeric member 26 provides, at least in part, elastomeric or resilient properties to neck 18. Accordingly, the degree of flexibility of neck 18 can be calibrated or tuned by adjusting the dimensions, shape, features, and materials of elastomeric member 26. For example, the harder or higher the durometer of elastomeric member 26, the less flexible neck 18 will be in the first orientation. Conversely, the softer or lower the durometer of elastomeric member 26, the less rigid neck 18 will be will be in the first orientation. In a preferred embodiment, elastomeric member 26 has a Shore A durometer of between about 40 and 90, with about 60 being preferred. Again, it should be recognized that one or more of the attributes of elastomeric member 26 can be varied along the length to provide the desired flexion.

(32) Moreover, it is contemplated for elastomeric member 26 to have different elastomeric properties (i.e., material or other attributes like thickness, shape, etc.) on one side of rib 24 than on the other side of the rib. In this manner, cleaning device 10 can be configured to have one level of flexibility when bending in one direction and a different level of flexibility when bending in the opposite direction. Moreover, it is contemplated that this embodiment of elastomeric member 26 can be combined with rib 24 of rectangular or circular cross sections.

(33) In use, cleaning member 10 can be oriented to allow the user deflect or flex neck 18 so that cleaning implement 12 can be presented to hard to reach places as needed.

(34) Importantly, device 10 has a flexion collar 28 that moves with respect to neck 18 between a first position 30 where movement of the neck is unrestricted by the collar as shown in FIGS. 2A, 2B, 3A, 3B, and 4A) and a second position 32 where movement of the neck is restricted by the collar (FIGS. 3C, 4B, and 4C).

(35) Neck 18—when the neck provides equal levels of flexion in all orientations—can have a stiffness ratio of flexion when collar 28 is in first position 30 to when collar 28 is in second position 32 of at least 1:2, more preferably at least 1:5, most preferably at least 1:20.

(36) In other embodiments where neck 18 provides different levels of flexion in different orientations, the neck can have a stiffness ratio of flexion—in the second or stiffer orientation—when collar 28 is in first position 30 to when collar 28 is in second position 32 of at 1:2, more preferably 1:5, most preferably 1:20.

(37) In some embodiments, neck 18 can have a flexion—when collar 28 is in first position 30—of about 1 N/m in the first orientation and a flexion of 5 N/m in the second orientation, but can have a flexion—when collar 28 is in second position 32—of 10 N/m regardless of the orientation.

(38) In the illustrated embodiment, the movement of neck 18 is shown as a linear or sliding movement along the longitudinal axis of handle 14.

(39) However, it is contemplated by the present disclosure for collar 28 to move in any desired manner between the first and second positions. For example, it is contemplated by the present disclosure for collar 28 to have a movement including sliding along the longitudinal axis, rotating around the longitudinal axis, rotating about an axis perpendicular to the longitudinal axis, radial clamping onto the longitudinal axis, and any combinations thereof.

(40) Preferably, device 10 is configured to provide feedback to the user during movement of collar 28 to first and second positions 30, 32. The feedback can be one of an audible feedback, a tactile feedback, and combinations thereof.

(41) In some embodiments, device 10 is configured to selectively hold collar 28 in the first position 30 or the second position 32. In this manner, collar 28 is configured to allow the user to device with two discrete levels of flexion (first position 30 or second position 32).

(42) In other embodiments, device 10 is configured to selectively hold collar 28 in a plurality of select positions between the first position 30 and the second position 32. In this manner, collar 28 is configured to allow the user to device with variable levels of flexion.

(43) Collar 28 can be selectively held in the desired position in any desired manner such as, but not limited to, one or more locking features 34 illustrated in FIG. 4C. Features 34 can be on neck 18, collar 28, or both the neck and the collar. Of course, it is also contemplated by the present disclosure for features 34 to be in any position on device 10, such as but not limited to on handle 14.

(44) In one embodiment illustrated in FIGS. 4D and 4E, collar 28 is configured to move in a combination of a sliding along the longitudinal axis and rotating around the longitudinal axis. Here, collar 28 includes feature 34a that has both a longitudinal region 34b and a rotational region 34c, where feature 34a cooperates with a corresponding feature 34d on handle 14. Rotational region 34c allows collar 28 to slide along the longitudinal axis, while the rotational region 34c allows collar 28 to rotate about the longitudinal axis. Rotational regions 34c (two shown) correlate to the first and second positions 30, 32, respectively.

(45) Accordingly, device 10 is provided with flexion—of variable levels via neck 18 and collar 28—which allow the device to be particularly suited for cleaning hard to reach places.

(46) Referring now FIG. 5, an alternate embodiment of cleaning device according to the present disclosure is shown and is referred to by reference numeral 110. Here, component parts performing similar or analogous functions are labeled in multiples of one hundred with respect to cleaning device 10.

(47) Cleaning device 110 is shown by way of example as having a cleaning implement 112 illustrated as a brush with the bristles removed for simplicity, but of course it is contemplated by the present disclosure for device 110 to find use with other cleaning implements. Device 110 can include one or more features such as, but not limited to, a handle or handle 114 and a telescoping device 116, which allows the handle to be telescope between extended and retracted positions in a known manner.

(48) Device 110 includes a flexible neck 118. In some embodiments, neck 118 provides a first level of flexion in a first orientation, but a second, lower level of flexion in a second orientation. In other embodiments, neck 118 provides equal levels of flexion in all orientations. Advantageously, device 110 has a flexion collar 128 that slides with respect to neck 118 between a first position where movement of the neck is unrestricted by the collar and a second position where movement of the neck is restricted by the collar.

(49) Referring now to FIGS. 6, 7A, and 7B, another alternate exemplary embodiment of cleaning device is shown and is referred to by reference numeral 210. Here, component parts performing similar or analogous functions are labeled in multiples of two hundred with respect to cleaning device 10.

(50) Device 210 includes a cleaning implement 212 and a handle or pole 214 (hereinafter “handle”). Device 210 is shown by way of example as having a cleaning implement 212 illustrated as a brush, but of course it is contemplated by the present disclosure for device 210 to find use with other cleaning implements.

(51) Device 210 can, in some embodiments, include a neck 218 alone or in combination with a collar 228. Neck 218 and collar 228, when present, can be as disclosed elsewhere herein.

(52) Device 210 can include a nested detail cleaning device 240 disposed within a free end 214a of handle 214 opposite cleaning implement 212. Detail device 240 includes additional cleaning implements 212a, 212b—illustrated as brushes—on one or more ends (both illustrated). In this manner, the user can clean larger surfaces with cleaning implement 212, and can clean smaller or more detailed areas with cleaning implements 212a, 212b of device 240.

(53) It should be recognized that nested device 240 is shown by way of example only as having brush bristles as cleaning implements 212a, 212b. Of course, it is contemplated by the present disclosure for nested device 240 to have one or more of any desired cleaning implement(s) 212a, 212b that are the same as or different from implement 212 and/or for detail device 240 to include any desired cleaning implements 212a, 212b on one or both ends. For example, it is contemplated by the present disclosure for detail device 240 to include cleaning implements 212a, 212b such as, but not limited to, a duster, a scrubber, a scraper, a squeegee, a mop, and any combinations thereof.

(54) Advantageously, device 210 is configured so that detail device 240 is—even when having cleaning implements 212a, 212b on both ends—is entirely within handle 214. Thus and as used herein, the term “nested” shall mean that detail device 240—including cleaning implements 212a, 212b—does not extend, along the longitudinal axis, beyond free end 214a of handle 214.

(55) To allow for removal of detail device 240 from device 210, device 210 includes a first opening 242 in handle 214 that allows access to nested device 240. Moreover, nested device 240 can include a second opening 244. In the assembled position, first and second openings 242, 244 are in registration with one another. In this manner and as shown in FIGS. 8-12, the user can place a finger through openings 242, 244 to apply a downward force (F) onto nested device 240 to force the nested device from handle 214. Similarly, the user can place a finger through holes 242, 244 to apply an upward force onto nested device 240 to force the nested device into handle 214 during assembly. Here, it can be seen that opening 242 is elongated to allow movement of the user's finger during installation and removal of the nested device 240. In this embodiment, the term nested also means that detail device 240 does not extend outward beyond handle 214.

(56) Nested device 240 can be selectively held in handle 214 in any desired manner such as, but not limited to the locking features 246 illustrated in FIGS. 13A and 13B. Features 246 can be on handle 214, device 240, or both the handle and the device.

(57) Device 210 can include flared end 248 at open end 214a. It has been found by the present disclosure that, when nested device 240 includes brush bristles, flared end 248 can minimize damage to the nested device (i.e., brush bristles) during installation into handle 214.

(58) Accordingly, device 210 provides the user with the ability to clean with cleaning implement 212—as well as implements 212a, 212b of detail device 240—which allow the device to be particularly suited for cleaning hard to reach places and allow the detail device to be readily available for specific cleaning functions such as, but not limited to, a detailed cleaning process.

(59) Referring now FIGS. 14 through 17, an alternate embodiment of cleaning device according to the present disclosure is shown and is referred to by reference numeral 310. Here, component parts performing similar or analogous functions are labeled in multiples of three hundred with respect to cleaning device 10.

(60) Cleaning device 310 is shown by way of example as having a cleaning implement 312 illustrated as a brush with the bristles removed for simplicity, but of course it is contemplated by the present disclosure for device 310 to find use with other cleaning implements. Device 310 can include one or more features such as, but not limited to, a handle or handle 314, neck 318, and collar 328.

(61) Device 310 includes a nested detail cleaning device 340 disposed within free end 314a of handle 314. Detail device 340 includes additional cleaning implements 312a, 312b—illustrated in FIG. 14 as a brush with bristles which have been removed from FIGS. 15-17 for simplicity—on one or more ends (both shown).

(62) Device 310 includes a pair of elongated openings 342 in handle 314. Moreover, nested device 340 includes a corresponding pair of protrusions 344. In the assembled position, openings 342 receive protrusions 344 therein. In this manner and as shown in FIG. 16, the user can apply a force (F) to insert or remove nested device 340 from handle 314 in a longitudinal direction of the handle.

(63) Nested device 340 can be selectively held in handle 314 in any desired manner. In the illustrated embodiment best shown in FIG. 17, openings 342 include one or more locking features 346 (two shown) disposed in at least one, but preferably both openings 342. Features 346 cooperate with protrusions 344 on device 340 to selectively secure the device in the handle 314.

(64) During insertion and removal, protrusions 344 act on features 346 to deflect one or more regions of handle 314 that are proximate to openings 342 outward so that the protrusions 344 can pass over the features. It has been determined that the simple shape of elongated openings 342 allow the end region of handle 314 to deflect outward to provide a simple and repeatable locking feature to hold nested device 340 in handle 314, yet allow removal of the nested device when desired.

(65) Again, device 310 is configured so that detail device 340 is—even when having cleaning implements 312a, 312b on both ends—is entirely within handle 314. Thus and as used herein, the term “nested” shall mean that detail device 340—including cleaning implements 312a, 312b-does not extend, along the longitudinal axis, beyond free end 314a of handle 314.

(66) Device 310 can include flared end 348 at free end 314a. It has been found by the present disclosure that, when nested device 340 includes brush bristles, flared end 348 can minimize damage to the nested device (i.e., brush bristles) during installation into handle 314.

(67) It should be recognized that nested device 340 is shown by way of example only as having brush bristles as cleaning implements 312a, 312b. Of course, it is contemplated by the present disclosure for nested device 340 to have one or more of any desired cleaning implement(s) 312a, 312b that are the same as or different from implement 312.

(68) Accordingly, device 310 is provides the user with the ability to clean with cleaning implement 312—as well as via cleaning implement(s) 312a, 312b of detail device 340—which allow the device to be particularly suited for cleaning hard to reach places.

(69) It should also be noted that the terms “first”, “second”, “third”, “upper”, “lower”, and the like may be used herein to modify various elements. These modifiers do not imply a spatial, sequential, or hierarchical order to the modified elements unless specifically stated.

(70) While the present disclosure has been described with reference to one or more exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the scope thereof. Therefore, it is intended that the present disclosure not be limited to the particular embodiment(s) disclosed as the best mode contemplated, but that the disclosure will include all embodiments falling within the scope of the appended claims.
