BACKGROUND
Powered wheelchairs occasionally require maintenance and repair. They are typically very heavy and can be difficult to stabilize during maintenance.
SUMMARY
In one embodiment, the techniques described herein relate to a wheelchair stand including: a base; a vertical support bar extending upward from the base; an upper bar extending transversely from the vertical support bar and spaced vertically away from the base; a hanger supported by the upper bar and spaced away from the vertical support bar; and a strap supported by the hanger.
A method of maintaining a wheelchair may include: a) moving the wheelchair to a position below a hanger; b) positioning a strap below the wheelchair; c) connecting the strap to opposite ends of the hanger; and d) shortening the strap to raise the wheelchair.

DETAILED DESCRIPTION
A wheelchair stand 10 according to one example is shown in FIG. 1. The wheelchair stand 10 includes a base 12, which includes a pair of runners 14 extending forward of a rear bar 16. A vertical support bar 18 extends vertically from the rear bar 16. As shown, the vertical support bar 18 may be formed in several connected segments. The rear bar 16 may be formed by two segments extending between the runners 14 to a lower end of the vertical support bar 18. Gussets (not shown) may connect the vertical support bar 18 to the base 12 to support the vertical support bar 18. An upper bar 20 is cantilevered from an upper end of the vertical support bar 18 and may be supported by a gusset (not shown) between the vertical support bar 18 and the upper bar 20.
The runners 14 and rear bar 16 may be metal hollow tubes of rectangular cross-section (such as 1″ by 2″). The vertical support bar 18 and the upper bar 20 may also be a metal hollow tubes (such as 2″ by 2″). The components may be formed of aluminum or steel and may be connected to one another, such as by welding. Alternatively, suitable plastics or composite materials could be used.
A ring 24 is mounted to the underside of the forward end of the upper bar 20. The ring 24 may be part of an eye bolt secured to the upper bar 20.
A hanger 26 is secured to the ring 24. The hanger 26 may have a central opening in which the ring 24 may be received. Alternatively, a connector (such as a loop or ring) secures the central opening of the hanger 26 to the ring 24. In this manner, the hanger 26 is pivotably secured to the upper bar 20. The hanger 26 may hang from an outer end of the upper bar 20 as shown.
A flexible strap 56 is connectable to each end of the hanger 26. At least one ratchet mechanism 58 (such as a ratchet on a ratchet strap) is provided on the strap 56. Loops or rings may connect the strap 56 and/or ratchet mechanism 58 to the outer ends of the hanger 26.
FIG. 2 is a top view of the wheelchair stand 10 of FIG. 1. As shown, the upper bar 20 is less than half the length of the runners 14. For example, the upper bar 20 may be 10″ and the runners 14 may 24″. The overall width of the base 12 in this example is 18″. The hanger 26 in this example is approximately 14″ long.
FIG. 3 is an enlarged view of the upper portion of the wheelchair stand 10 of FIG. 1. As shown, the hanger 26 is elongated, solid and narrow and includes a central portion 28 that is curved to be convex facing upward. Outer ends 30 of the hanger 26 curve sharply upward to provide hooks on which to retain straps, loops, rings, or chains.
FIG. 4 is a section view of the wheelchair stand 10. The sections of the vertical support bar 18 may be connected by connectors 32 received within adjacent hollow sections.
FIG. 5 is a side view of the wheelchair stand 10.
FIG. 6 shows the wheelchair stand 10 in use. A powered wheelchair 50 is moved to a position over the base 12 of the wheelchair stand 10, with the base 52 of the wheelchair 50 over the runners 14 and the wheels 54 of the wheelchair 50 on either side of the runners 14. The base 52 of the wheelchair 50 may abut the vertical support bar 18. A strap 56 is secured to the outer ends 40 of the hanger 26 and looped below the base 52 of the wheelchair 50.
Referring to FIG. 7, the ratchet mechanism 58 is actuated in order to shorten the strap 56, thereby raising the wheelchair 50 off the floor. Then the user can perform maintenance and repairs on the wheelchair 50, such as removing/replacing the wheels 54. When complete, the user can release the ratchet mechanism 58 to place the wheelchair 50 on the floor and then remove the strap 56.
The wheelchair stand 10 makes it easier to repair and maintain a powered wheelchair.
In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
