  • Patent number: 4190263
    Abstract: The invention consists of a device which can be mounted on a conventional wheelchair to provide shock absorbing qualities to the wheelchair. Each wheel on the wheelchair is removed from its standard mounting position with a shock absorbing device of this invention being used to mount each wheel in a new position spaced longitudinally from its standard position. The device of the invention has a lever with one hole in front which is attached to the axle of the wheelchair by means of a bolt which passes through the hole in the axle and a nut attached to the end of the bolt. Another hole is located centrally in the lever for mounting of the wheel by means of a second bolt and a second nut. At the opposite end of the lever a hole is provided through which a spring is attached. The opposite end of the spring is attached to a rigid member of the wheelchair. In this manner, the weight of the chair and its occupant is supported by the spring tension of the spring.
