The following includes information that may be useful in understanding the present invention(s). It is not an admission that any of the information provided herein is prior art, or material, to the presently described or claimed inventions, or that any publication or document that is specifically or implicitly referenced is prior art.
The present invention relates generally to the field of lever devices and more specifically relates to improved handle cover apparatus.
Many of the residents in assisted living and senior car facilities have difficulties using the handbrakes on their wheelchairs. Many had arthritis in their hands, and their palms hurt when they must exert pressure on the small brake handle. The rubber cover on the brake handle wears off or slips off easily, leaving just hard metal exposed. Many residents wrapped their handles with layers of duct tape or cloth to provide some protective padding. When the rubber covers come off, they get kicked around and lost, and the pressure of the bare metal against their palms and thumbs makes it extremely painful to use the brakes. The pain that occurs after periods of increased joint use, such as gripping and grasping the metal handles is intense and aggravates their arthritis.
Sometimes users chip their thumbnails or bend them, which causes a different kind of pain. They must do this so many times, every day of their lives, and end up developing visible swelling in the thumb joint over time. In the USA alone, it is estimated there are more than 1.6 million residents in registered nursing-home beds. Of this number, 3% or 48,000 residents are developing arthritis, and 19% or 304,000 already have arthritis, with many more still living at home. These are the same people who depend on wheelchairs for their mobility, and their handbrakes need to be more comfortable to use, so their mobility is not limited because of their inability to apply the brakes. Therefore, a need exists for a specially designed new wheelchair accessory, which will ensure users greater comfort when using the hand brakes on their wheelchairs.
None of the previous art or patents, taken either singly or in combination, is seen to describe the invention as claimed. Ideally, a lever device should provide improved leverage and grip comfort, and yet, would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable improved handle cover apparatus to avoid the above-mentioned problems.
In view of the foregoing disadvantages inherent in the known lever device art, the present invention provides a novel improved handle cover apparatus. The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a improved leverage and grip comfort.
The improved handle cover apparatus for use upon brake handle members may comprise an elongated main body including an outer surface, an inner surface that surrounds and defines an interior volume, a plurality of adaptor members each including an outer surface adapted to frictionally and removably engage the inner surface of the elongated main body, an inner surface that surrounds and defines the interior volume that is adapted to slide over to releasably and frictionally fit upon a wheelchair brake handle, and each of the adaptor members are sized and shaped to be frictionally and removably placed within the interior volume of the elongated main body.
The cross-section of the interior volume of each adaptor member is formed having a shape different from the other adaptor members such that an adaptor member can be chosen from the plurality of adaptor members that is most similar to the cross-section of the brake handle member it is to be placed upon. The cross-sections of the interior volume of the plurality of adaptor members are chosen from a group of cross-sectional shapes consisting of square, rectangular, and circular. The group of cross-sections of the interior volume of the plurality of adaptor members includes hexagonal.
The elongated main body is formed from acetal. The elongated main body is formed from a thermoplastic elastomer. The elongated main body further includes an elongated finger grip member attached to the outer surface thereof that includes a plurality of finger ridges thereon and is adapted and shaped to allow a user to more easily and securely grip the improved handle cover apparatus. The elongated main body is formed from acetal, and the elongated finger grip member is formed from a thermoplastic elastomer. The elongated main body further includes an elongated palm grip member attached to the outer surface on the opposite side from the finger grip member and is formed from a thermoplastic elastomer, and is adapted to allow a user to more easily and securely grip the improved handle cover apparatus. The elongated main body is formed having a curved shape along its length to thereby further allow a user to more easily and securely grip the improved handle cover apparatus.
The improved wheelchair apparatus preferably comprises a wheelchair including a brake handle member having a cross-sectional shape, and an improved handle cover apparatus for use upon the brake handle member comprising an elongated main body including an outer surface, an inner surface surrounding and defining an interior volume, a plurality of adaptor members each including an outer surface adapted to frictionally and removably engage the inner surface of the elongated main body, an inner surface that surrounds and defines the interior volume and is adapted to slide over and releasably and frictionally fit upon the wheelchair brake handle. Each of the adaptor members are sized and shaped to be frictionally and removably placed within the interior volume of the elongated main body.
A cross-section of the interior volume of each respective adaptor member is formed having a shape different from the other adaptor members such that an adaptor member can be chosen from the plurality of adaptor members that is most similar to the cross-section of the brake handle member. The cross-sections of the interior volume of the plurality of adaptor members are chosen from a group of cross-sectional shapes consisting of square, rectangular, circular, and hexagonal. The elongated main body may be formed from acetal or from a thermoplastic elastomer. The elongated main body further may include an elongated finger grip member attached to the outer surface thereof that includes a plurality of finger ridges that is adapted and shaped to allow a user to more easily and securely grip the improved handle cover apparatus.
