Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a biodegradable and recyclable cover for a wheel chair which can be discarded and replaced with a new cover each time the wheelchair is used.
2. Description of Related Art
Covers for covering wheelchairs are known in the prior art. More specifically, by way of example, U.S. PreGrant Publication No. 2008/0047071 to Christofferson, et al, discloses a seat cover which minimizes surface tension in the cover material when the cover conforms to a highly contoured shape.
U.S. PreGrant Publication No. 2004/0041449 to Bluhm discloses a wheelchair slipcover which has a seat pad slipcover that can contain a cushion. The seat pad slipcover can be made from decorative material and can be attached to the seat of a wheelchair. A back pad slipcover can also be made from the same or different decorative material, and can be attached to the back of the wheelchair.
U.S. Pat. No. 7,278,649 to Daniels discloses a wheelchair cover having a first and a second covering member. The first covering member has a back cover portion which covers a back of a wheelchair, and first and second arm covering portions for covering first and second arms which extend from the back of the wheelchair. The second covering member, is removably attached to the first covering member and has a seat covering portion for covering a seat of the wheelchair. The wheelchair cover further includes a third covering member which covers a cushion placed on the seat. First and second side skirts extend from the first and second arm covering portions cover the first and second side of the wheelchair and a back skirt extending from the back covering portion covers a wheelchair back side. A front skirt covers the wheelchair front side.
U.S. Pat. No. 6,866,337 to Lash discloses a protective cover for a wheelchair which includes a first cover section and a second cover section. The first and second cover sections form a contiguous unit having a first surface and a second surface. The protective cover wraps around either a seat or back of the wheelchair so that the first and second cover sections reside on opposite sides of the seat or the back. Fastening elements detachably couple a fourth edge of the second cover section with a first edge of a first cover section to form a closed loop around the seat or the back. The protective cover may optionally include cushions for occupant comfort.
U.S. Pat. No. 6,312,051 to Adams discloses a cover for a wheelchair seat made from a cloth having a first ply of wicking material for drawing moisture that contacts the first ply away from an occupant of the wheelchair and a second ply of absorbent material for drawing moisture out of the first ply and dispersing the drawn moisture in the second ply. The first and second plies are permanently secured in laminar relationship to each other by a hem along their perimeter. The cloth is detachably mounted on the wheelchair seat, either by an elastic band positioned within the hem, where the band has a length in its unstretched state which is less than the length of the hem, or by a plurality of hook-and-loop fasteners fixed in spaced apart relationship to the cloth and which extend outwardly from the hem to a plurality of mating hook-and-loop fasteners fixed to the cloth near the hem. A third ply of impermeable material for preventing moisture from passing from the second ply into contact with the wheelchair surface may be disposed against the opposite side of the second ply as the first ply with all the plies being secured in laminar relationship with each other by the hem.
U.S. Pat. No. 5,568,660 to Raburn, et al. discloses a soft pressure relieving cushion for wheelchair patients made of a high density foam, such as 2.4 pounds per cubic foot or above and a 25 percent ILD characteristic of at least about 50 pounds, together with independently acting cube shaped segments. The segments have predetermined respective separation and rounded upper edges with a predetermined radius of curvature which is larger about the periphery of the wheelchair pad. A relatively lowered pad thickness of about 3 inches facilitates patient movement onto and off from a wheelchair cushion. A removable covering of laminated materials is stretchable so as to slide over the rounded edges of the segments and down into separations therebetween to maintain independent action of such segments during use with the covering. An upper layer of the covering comprises a base layer of woven fabric of elastic synthetic fibers. A lower layer of the covering comprises a water resistant coating of urethane generally at least about 1 mil thick.
U.S. Pat. No. 5,333,921 to Dinsmoor, III discloses an adjustable cover and seating system for a wheelchair. The cover has an enclosing portion surrounding the inner seat members and a skirt portion extending about the sides of the enclosure portion and downwardly under the lower section of the enclosure portion. The enclosure portion of the cover can be placed over the seating members and secured in place by a zipper to encase the seating member. The skirt section is then pulled to draw the skirt section downwardly which, in turn, draws the upper section of the enclosure portion snugly across the top of the seating members. In doing so, the peripheral side section of the enclosure portion is also drawn downwardly on itself into bunches which are held firmly in place against the seating members by the skirt section. This serves to prevent excess material from catching in the spokes of the wheelchair.
U.S. Pat. No. 5,170,826 to Carstensen, et al. discloses a cover for a wheelchair having a hood portion. The hood portion has an upper end and at least two sides extending from the upper end. The sides define an opening opposite the upper end for a person to enter. A flap member extends from a first side of the hood portion which is adapted to be wrapped across a portion of the opening.

DESCRIPTION OF THE PREFERRED EMBODIMENT

This invention relates to a slip cover for use with a wheelchair seat and seat back. At the present time wheelchairs are provided for short term use of an hour, more of less, by an individual, or they are rented for use by an individual for a few weeks or months, or they are purchased outright.
A wheel chair is provided for short term use to help move a person from one location to another at, for example, a hospital to transport a person from his/her hospital room to a waiting car or taxi at the front door of the hospital. In other instances a wheelchair will be used to move a patient from his/her room to another floor in a hospital for a medical procedure such as an Xray. In still another instance a wheel chair may be used to help move an incoming patient from a taxi to an emergency room or the admittance desk of the hospital. In other instances it is common to use a wheelchair at airport terminals to help transport an elderly passenger from his/her car or taxi to the boarding gate of a departing airplane.
More extensive but temporary use of a wheelchair is where a person suffers a temporary injury such as a badly sprained or broken foot or leg. In this instance the person will rent a wheelchair for a few weeks or months for use only while at home and will rely on crutches when going out to work, to a restaurant, etc. In other situations the wheelchair is owned by the individual and is used either for short periods of time each day or continuously by the owner.
Thus, wheelchairs that are used in hospitals, at airport terminals, in nursing homes and even wheelchairs that are rented for an extended period of time or owned by a person can present a sanitary problem by not being thoroughly cleaned and/or sanitized between use by different users. Where the wheel chair is rented or owned and used by a single person, it should be cleaned at least once a week. The present invention discloses a new improved cover which provides a simple and economical way of maintaining wheelchairs in a clean and sanitary condition.
Referring to FIG. 1, there is shown a plan view of a cover 10 for use on the seat of a wheelchair. The cover 10 is an elongated, substantially rectangular member that includes a seat portion 12 having two sets or more of similar openings at its lower end. One or more sets of openings 14 is located at the lower left corner of seat portion 12 and the second set of openings 16 is located at the lower right corner of seat portion 12. Seat portion 12 can have a width of about 32 inches, more or less and a length of about 40 inches, more or less and can be made of paper of any desired grade or of a plastic which can be coated or impregnated with a antimicrobial agent, and the seat cover can be of any desired color.
Referring to the openings in the lower left hand corner of the seat portion 12, each set of openings 14 has five individual opening 18, 20, 22, 24 and 26 where each opening has a diameter of between one half of an inch and six inches, more or less. The openings in set 16 in the lower right hand corner of seat portion 12 has five individual openings 28, 30, 32, 34 and 36 which are a mirror image of the openings in set 14 and each opening has a diameter of about two inches, more or less. Openings 18, 20 of set 14 are aligned with openings 28, 30 of set 16 along a straight line where the center of opening 18 is about two inches in from the left end of the seat portion. The center of opening 20 is about three inches from the center of opening 18, the centers of openings 20, 28 are about twenty inches from each other, and the center of opening 30 is about three inches from the center of opening 28. The center of each opening 18, 20, 28 and 30 is located about two and one-half inches from the bottom edge of seat portion 12.
Opening 22 of set 14 is aligned with opening 32 of set 16 and their centers are about two and three-quarters of an inch above the centers of openings 18, 20, 28 and 30. The center of opening 22 is located about one inch to five inches in from the left edge of seat portion 12 and the center of opening 32 is about twenty four inches from the center of opening 22.
Openings 24, 26 of set 14 are aligned with openings 36, 34 of set 16 along a straight line where the center of opening 24 is about one inch in from the left end of the seat portion. The center of opening 26 is about three inches to the right of the center of opening 24, where the centers of openings 26, 36 are about twenty two inches from each other, and the center of opening 34 is about three inches from the center of opening 36. The center of openings 24, 26, 36 and 34 are located about two and three-quarter inches above the centers of openings 22, 32. The seat portion 12 can be of any biodegradable and recycled material where the material can be cloth, paper, plastic or a combination of these which can be coated or impregnated with a antimicrobial agent.
In another embodiment of the invention, in place of each opening in set 14, 16, seat portion 12 can have a horizontal slit, a vertical slit, or a horizontal slit bisected with a centrally located vertical slit.
In another embodiment of the invention, in place of each opening in the sets 14, 16, seat portion 12 can have push out openings or precut openings which are formed by pushing out two inch diameter perforated paper circles located on the seat portion 12. In this embodiment an opening is obtained by pushing or tearing along the circle of perforations in the seat portion where an opening is desired.
To use, a person stands behind a wheelchair, places the seat portion 12 on top of the handle bars of the wheelchair and slides the handle bars through aligned openings of the sets of openings 14, 16. The seat portion has a front to back dimension which is at least equal to the depth of the seat of the wheelchair and a side to side width dimension which is at least equal to the width of the seat of the wheelchair plus twice the distance from the top of the handle bars down to the wheelchair seat. After the handle bars are slid through the openings of the sets of openings, the seat portion is pressed down along the insides of the handle bars and onto the seat of the wheelchair to provide a U shaped channel for a person to sit in.
