BACKGROUND
In the Parent Application improvements in handicap apparatus are disclosed. Crutches, walkers, scooters and wheel chairs, and other apparatus for assisting handicapped individuals typically do not have means to adequately elevate the leg of a user while seated. Many handicapped patients, however, have poor circulation, especially in their legs. Elevating their leg or legs would be beneficial. Nor does such handicap apparatus usually provide a leg pillow type structure for the comfort of the user. Moreover, the tips of crutches disclosed in the Parent Application that engage the ground are problematic, for example, attached tip covers frequently detach. The bumper structures and other features disclosed in the Parent Application can also be enhanced as discussed herein.

SUMMARY
My handicap apparatus and method of use have one or more of the features depicted in the embodiments discussed in the section entitled “DETAILED DESCRIPTION OF SOME ILLUSTRATIVE EMBODIMENTS.” These features are not listed in any rank order nor is this list intended to be exhaustive. The claims that follow define my handicap apparatus and method of use, distinguishing them from the prior art; however, without limiting the scope of handicap apparatus and method of use as expressed by these claims, in general terms, some, but not necessarily all, of their features are:
One embodiment of handicap apparatus is crutch including one or more resilient, snap-on bumper structures. Such a structure is mounted to one or more of the poles of the crutch in a manner that the structure projects outwardly from the poles. The bumper structures comprise a resilient body that varies in density to provide a softer exterior and a harder interior. For example, the resilient body may be rubber. A connector element can be used to attach a pair of crutch side poles together that functions as a handle that extends between the side poles and is positioned so a user can grasp the connector element while using the crutch. This connector element may have a resilient body that varies in density to provide a softer exterior and a harder interior. An upper end portion of a center pole of the crutch may have a cap member attached thereto in the form of a bumper structure comprising a resilient body that varies in density to provide a softer exterior and a harder interior.
Two, in a second embodiment of my handicap apparatus a lower end portion of a central pole of the crutch terminates in a tip that is inserted into a tip cover. The tip cover has a rigid body forming a receptacle with a floor and a open mouth that receives the tip of the center pole. The floor may include a honeycomb matrix of spaced apart open spaces in the body.
Three, in a third embodiment of my handicap apparatus the tip cover may be detachable. For example, a fastener passes through the tip cover to connect the tip cover to a pole of the apparatus. Typically, the pole is elongated and rigid, having a hollow interior and terminating in an edge. A plug is inserted into the hollow interior, being configured to fit snug within the interior. This plug has a face end including a rim projecting generally at a aright angle from a side of the plug that abuts and overlaps the edge upon insertion of the plug into the hollow interior. The rim acts as a stop to prevent further movement of the plug into the interior of the pole upon engaging the edge. The plug may have in the face end a site configured to attach an end of a fastener.
In this third embodiment of my handicap apparatus a tip cover is employed that is configured to receive the pole with the plug therein and has a rigid body including a top end, a bottom end, and a receptacle. The receptacle extends from the top end partially into the body and terminates in a floor with a passageway that extends from the floor to the bottom end. The passageway terminates in the bottom end in a recess. A fastener, for example a bolt or screw, extends through the passageway. This fastener has a first end that attaches to the site at the face end of the plug, pulling the rim of the plug snug against the floor of the receptacle as the fastener is attached, and a second end that is seated in the recess inward of the bottom end when the fastener is completely tightened. The edge has a perimeter with predetermined dimensions, for example, circular, and the rim generally has the same dimensions as the perimeter of the edge and the receptacle has perimeter dimensions the same as the perimeter of the edge to fit snug within the hollow interior. The pole has a central reference line and the rim is at a right angle to the reference line, and the rigid body comprises a molded rubbery material.
In a fourth embodiment, an elevation unit is employed for elevating a leg of a user while the user is in a seated position. In this fourth embodiment, an elongated platform is configured to be mounted to a handicap apparatus, for example, a crutch, walker, scooter, or wheelchair. The platform may have a predetermined shape enabling the leg of a patient to be positioned comfortably lengthwise along the platform. The platform has opposed ends and is moveable between a first position where a first end of the platform is elevated with respect to a second end of the platform. A lifting mechanism is included that enables a patient to manually move the platform between the first and second positions and move the elevated platform laterally. For example, the second end is mounted to pivot and the lifting mechanism includes legs at the first end that are extended upon elevating the platform into the first position. The platform may include a pillow member that at least partially covers the platform. The pillow member may be detachably connected to the platform.
My method improves circulation in a leg of a patient and comprises the steps of
(a) placing one end of a crutch on a seat, said crutch including an elevation unit with an elongated platform positioned lengthwise along the unit, the platform having opposed ends and being moveable between a first position where a first end of the platform is elevated with respect to a second end of the platform, and
(b) with the patient siting in a seated position on the seat, placing one leg of the patient on the elevated platform. The elevated leg is horizontally oriented or above the horizontal by no more that 35 degrees.
These features are not listed in any rank order nor is this list intended to be exhaustive.

DETAILED DESCRIPTION OF SOME ILLUSTRATIVE EMBODIMENTS
The features of my handicap apparatus include an elevation unit 100 for the elevating the leg of a user while the user is in a seated position as best illustrated in FIGS. 11A and 11B; a unique handle 200 depicted in FIGS. 33 through 39; a snap-on bumper structure 300 shown in FIGS. 48 through 53; and a unique tip cover for a pole of any of my handicap apparatus such as shown in FIGS. 54 through 60 or the cane pole 500 shown in FIGS. 67 through 69, a cane pole 502 shown in FIGS. 70, 70A and 70B, and a cane pole 502 shown in FIGS. 71 and 71A through 71C. One or more of these and other features of my handicap apparatus may be used with crutches 10a (FIG. 1), 10b (FIG. 2), 10c (FIG. 3), and 10d (FIG. 4), a wheelchair 180 (FIG. 18), a walker 22 (FIG. 22), a scooter 185 (FIG. 25), and the canes 500 (FIG. 67), 502 (FIG. 70) and 504. (FIG. 71).
There are four embodiments of my unique tip cover. The first embodiment depicted in FIGS. 56 through 60 and generally designated by the number 400a. The second embodiment depicted in FIGS. 61, 63, and 67 through 69 and generally designated by the number 400b. The third embodiment depicted in FIG. 65 and generally designated by the number 400c. The fourth embodiment depicted in FIG. 66 and generally designated by the number 400d.
The elevation unit 100 is configured to be mounted to a handicap apparatus such as a crutch, scooter, wheel chair, walker or other handicap apparatus. In the case of a crutch where a pole structure extends from an underarm support member, the elevation unit 100 is attached to the pole structure, lying lengthwise generally along a longitudinal central reference line RL of the crutch. In the case of scooter, wheel chair, walker, the elevation unit 100 is attached to extend from a seat outward horizontally or above the horizontal by no more that 35 degrees. When my method is employed using a crutch as shown in FIGS. 11A and 11B, the patient's leg is horizontally orientated or above the horizontal by no more that 35 degrees.
FIGS. 18, 22, and 25 depict apparatus for enabling a handicapped user to be seated and mobile, and while seated provides additional elevation for a leg of the user using the elevation unit 100. FIG. 18 shows a wheel chair 180 employing the unit 100; FIG. 22 shows a walker 183 employing either one of the embodiments 100a and 100b of the elevation unit; and FIG. 25 shows a scooter 185 employing anyone of the embodiments 100c, 100d, 100e, 100f and 100g of the elevation unit. In the wheelchair 180 the elevation unit 100 is mounted on the wheel chair's leg that has been raised to its maximum height. The unit 100, upon elevation of its platform 103, adds extra height to the raised wheelchair leg.
As illustrated in FIGS. 23 and 24, either a support unit 100a or unit 100b is mounted to the walker 183. These units 100a and 100b each a case 191 having attached thereto a pad (a pair of pads 190a in unit 100a and a wide unitary pad 190b in unit 100b). The case 191 is mounted to an underside of the seat 183a of the walker 183 and the pad 190a or 190b as the case may be is initially rolled up for storage when not in use as shown in FIG. 24C. FIGS. 24A and 24B illustrate an extension system 193 retained in the case 191. The extension system has arms AA interconnected crosswise and that are movable between a retracted state (FIG. 24C) and an extended state (FIG. 24B). In FIG. 24D the alternate embodiment of the extension system for the support unit shown in FIG. 24 has arms AAA that telescope to move between retracted and extended states. In the extended state the extension system 193 unrolls the pad 190a or 190b as the case may be and provides support for the user's leg or legs in a horizontal orientation or above the horizontal by no more than 35 degrees.
In a similar fashion, the scooter includes the platforms 103 of the elevation units 100c, 100d, 100e, 100f and 100g that extend at or above the horizontal from the seat 185a of the scooter 185. The elevation units 100 may be a pair of platforms or a wider, unitary platform. In either case these units 100 have extendable legs L that allow the platforms 103 to be raised and lowered. The elevation units 100 may also include battery powered heating elements 170 shown in dotted lines and embedded with pillow members 150 or the seat portions 109a of the scooter 185. FIG. 26 shows a cap member 185b attached by a two-component bracket 185c to the end of an arm of the scooter 185. The cap member may be made of rubber or be a battery powered light. The rubber's density may vary to provide a softer exterior and a harder interior. FIG. 27 illustrates an extension member 153 adapted to be attached to an end o the platform of my elevation unit.
As best shown in FIGS. 10A through 10M, a lifting mechanism 600 is used that enables a patient to manually move the platform 103 between first and second elevated positions and also move the elevated platform laterally. The lifting mechanism 600 comprises a forward mount 610 and a rearward mount 620 connected by a pair of L-shaped legs L1 and L2, with opposed ends of a pair of leg segments a1 and b1 of the L-shaped legs respectively attached to either mount 610 or 620 as the case may be. The forward segments a1 of the L-shaped legs are telescoped so the multiple components of segments a1 and b1 collapse into each other to lower the platform 103. The platform 103 is manually raised by pulling on the collapsed multiple components to elevate the forward end of the platform.
As shown in FIGS. 10D through 10I, the forward mount comprises a pair of circular disks 610a and 610b of the same diameter overlying each other that are attached together to side latterly along a slot 610c. Spring loaded pins 611 hold the disk together but are manually lifted to disengage and allow the upper disk 610a to move either to the right (FIG. 10G) or left (FIG. 10H). In the bottom of the disk 610b are a pair of feet 613 that project outward from the bottom of the disk 610b and fit into orifices in the handicap apparatus to attach the mount 610 thereto. As shown in FIGS. 10J through 10M, the mount 620 includes a pair of circular disks 620a and 620b of the same diameter overlying each other and attached together to rotate relative to each other. An arm 615 that has an end that fits into holes 617 in the upper disk 620a will drop into position as the upper disk moves relative to the lower disk. There is a pair of feet 613 that projects outward from the bottom of the disk 620b and fit into orifices in the handicap apparatus to attach the mount 620 thereto. As shown in FIG. 10N an alternate lifting mechanism is depicted similar to that discussed above but uses at the forward end a mount 630 with telescopic legs 631. This mount may simply be shifted from side to side after raising the legs 631.
As illustrated in FIGS. 11A and 11B, the elevation unit 100 mounted to a crutch 650 is also used to elevate the leg of a user while the user is in a seated position. In this case the crutch is positioned to lean against a seat upon which a patient sits. The elevation unit 100 comprises an elongated platform 103 (FIG. 10) having opposed ends 103a and 103b and being moveable between a first position where the end 103a of the platform is elevated with respect to the end 103b of the platform. For example, the end 103b may be mounted to enable the platform to pivot about this end 103b. The unit 100 includes legs 105 that are extended upon elevating the platform 103. The platform 103 may also be mounted as shown in FIG. 8. As shown in FIGS. 19 through 21, the elevation unit 100 may have a joint at the end 103b that allows the platform 103 to pivot and also move laterally from side to side. A sheath 109 with straps 113 allows a user to wrap the sheath around the platform 103 and hold in position using the straps 113.
As shown in FIGS. 9 and 12 through 17, a cup shaped pillow member 150 may be used to cover the platform 103 and provide a soft comfortable support for the user's leg. As shown in FIG. 9, the pillow member 150 includes a central depression D and may be detachably connected to the platform 103 by a hook H at an end of the depression. As illustrated in FIG. 14, the flat underside of the pillow member 150 may have a precisely configured indentation 105 (FIG. 15) that conforms in shape to a leg rest 107 of a wheelchair. FIGS. 16 and 17 depict a pillow member 150a with elongated slots 109 in its flat underside that receive finger elements that fit in the slots to hold the pillow member in position. The pillow member 150 or 150a may have sides 150b that stretch as shown in dotted lines in FIG. 17. The pillow member 150 may have a blanket 160 component attached along an edge 161 that may be placed over the user's leg when the leg is seated in the depression D.
The crutches 10a through 10d are similar to those illustrated in the Parent Application, with the crutches depicted in FIGS. 1 through 3 including my elevation unit 100. The crutch 10d shown in FIG. 4 employs a plurality of snap-on bumper structure 300 and a snap-on light element 13. The crutches 10a through 10d all include an elongated center pole 15 positioned between lower portions of a pair of side poles 17a and 17b. The side poles 17a and 17b and center pole 15 are connected together into an assembly where the center pole extends along the longitudinal central reference line RL and the side poles straddle the reference line. All the poles 17a, 17b and 15 lie in the same plane and are parallel to each other. A plurality of resilient, snap-on bumper structures may be mounted to one or more of the poles in a manner to project outwardly from the pole and lie generally in the same plane as the assembled poles 17a, 17b and 15.
As shown in FIGS. 48 through 50 the bumper structures 300 are unitary molded rubber pieces that include an enlarged portion 300a and a coupling portion 300b rearward of the enlarged portion 300a, which may be in the form of an ornament, for example, a dog's head. The enlarged portion 300a projects outwardly away from a pole upon attachment. The coupling portion 300b includes a pair of fingers A and B that are spring biased. The fingers A and B have an open configuration shown in FIG. 49 and a closed configuration shown in FIG. 50, for example, the finger A and B wrap around the pole 17a upon being manually pushed together. A light 311 may be mounted to a pole in a similar manner as shown in FIGS. 52 and 53.
As shown in FIG. 4, an upper end portion of the center pole 15 has a cap member such as the bumper structure 300 attached thereto. This bumper structure 300c is similar to the bumper structure 300. Instead of a snap-on mounting device, as shown in FIGS. 45 and 46 bumper structure 300c lower portion 301 is threaded and screws into an internal thread (not shown) at the upper end of the center pole 15. In general, a bumper structure 350 may have two components #1 and #2 as shown in FIGS. 40 and 41, and have an external flange 310. Also in general, a bumper structure 360 (FIG. 42) may have an external flange 310, or a bumper structure 370 (FIGS. 43 and 44) may have an external flange 315.
The various bumper structures 300, 300c, 350, 360, and 370 may comprise a resilient rubber body that varies in density to provide a softer exterior and a harder interior.
As shown in FIGS. 33 through 39 a connector element attaching the poles 17a and 17b together functions as a handle 200 that extends between these side poles and is positioned so a user can grasp the handle while using the crutch. As illustrated in FIG. 37, the handle 200 has a resilient body B that varies in density to provide a softer exterior and a harder interior. Goodyear Rubber Company is expert in making rubber structures that vary in density in this manner.
As shown in FIGS. 54 through 60 and FIGS. 67 through 69, my tip cover may be used with a crutch pole, for example, the pole 15, or a cane 500. All the embodiments of my tip cover have a rubber body 410 generally in the shape of a truncated cone. As best shown in FIG. 58, this body 410 has a generally flat bottom 412 and a flat top 414 having a receptacle 416 therein in the form of a cylinder that is configured to receive the end of the pole 15 or cane 500 as the case may be. As best shown in FIG. 56, molded into the bottom of the receptacle 416 is a disk shaped matrix 418 of adjacent diamond shaped opening 420 within a circular rim 422 having a diameter the same as the diameter of the cylindrical receptacle 416. As best shown in FIGS. 56 and 61, in the bottom 412 are crisscrossing grooves 430.
In the tip cover 400a there are no openings in a sidewall 410a (FIGS. 58 and 61) of the body 410. The receptacle 416 of the tip cover 400a has tight dimensions so the end of the pole 15 fits snug and the elastic character of the rubber body 410 holds the tip cover in place. Whereas in the tip cover 400c there is a pair of aligned openings 410b in this cover's sidewall. As shown in FIG. 65, upon inserting the end of the pole 15 into the receptacle 416 and moving the pole inward to bear against the matrix 418, fasteners such as screws 410c are screwed into the openings 410b so their ends press against the pole 15 to hold the tip cover in place.
As shown in FIGS. 61 and 63, the bottom 412 of the tip cover 400b has a central opening 412a therein that is in communication with an aligned central opening 412c in the matrix 418 to form a passageway through the tip cover's bottom into the receptacle 416. As depicted in FIGS. 62 and 64, a plug 450 is inserted into the open end of any of the poles 15. A central threaded receptacle 412b in a face end of the plug provides an attachment site that is aligned with the openings 412a and 412c forming the passageway. This passageway terminates in a recess near the bottom 412, and a threaded fastener 452 extends through the passageway P. A first end of the fastener 452 attaches to the site by being screwed into the receptacle 412b, pulling the rim 422 of the plug 450 snug against the floor of the receptacle 416 in the rubber body 410, and a second end that is seated in the recess R inward of the bottom 412. A central threaded receptacle 412b in the plug 450 is aligned with the openings 412a and 412c and a screw 452 is screwed into the receptacle 412b to hold the tip cover 400b in place.
In the tip cover 400d, the end 15a of the pole 15 is threaded and the lower inside surface 416b of the receptacle 416 has corresponding threads so that the end of the pole is screwed into the receptacle as shown in FIG. 66.
The Goodyear Rubber Company can manufacture such tip covers using conventional molding techniques.
SCOPE OF THE INVENTION
