摘要:
A wheelchair assembly for propelling a wheelchair is provided. The wheelchair has front wheels and rear wheels and a pair of armrests. The wheelchair assembly comprises a first gear wheel secured to each rear wheel and a second gear wheel secured to each armrest. The second gear wheel is positioned directly over the first gear wheel with the second gear wheel being completely encased by a cover. A chain is secured over and between the first and second gear wheels and extends from an opening in the cover. Rotatable handles are attached to each armrest with each having a grasping portion extending Upward. A control linkage extends between the handles and the second gear wheels and mounted to and under the armrest such that rotation of the handles also rotates the second gear wheels with the control linkage being perpendicular to the line formed between the first and second gear wheels.
