Abstract
Adjustable wheelchair with a frame on whose sides the wheel axles of hand-driven rear wheels are mounted on mounts provided on the frame with a negative camber, i.e., closer together at top than at bottom. The mounts each have a mounting part in which there is an inclined bore hole holding the rear wheel axle in order to achieve the negative angle. The mounting parts 16 of the wheel axles 8 on both sides are arranged so they can rotate independently of each other in the respective mounts 6 and can be secured in any set rotational position. By releasing the mounts, the mounting parts can be rotated to change the direction of the rear wheels to eliminate toe-in or tow-out. Thus, any desired variation in the angle of the rear wheels is possible and/or any toe-in or toe-out tendency can be corrected.
Claims9
An adjustable wheelchair having a frame,
- a mount for a drive wheel connected to said frame at each side thereof, each mount comprising,

- a cylindrical axle support rotatably mounted on said base,
- a bore in said axle support inclined at a fixed angle to the axis of said cylindrical axle support,
- an axle fixed in said bore for one of said wheels, and
- means for securing said cylindrical axle support in any rotational position for adjusting the camber of wheels mounted in said bores at each side of said frame.
