Wheelchair exercise apparatus

Abstract

An exercise apparatus for a wheelchair has a raised platform with an upper surface which will support a wheelchair. Front and rear rollers mounted rotatably on the platform project slightly above the platform upper surface to support the driving wheels of the wheelchair. One of the rollers is connected to a flywheel which provides momentum to even out the movement of the rollers and the driving wheels between strokes of the person driving the wheelchair. One or more attachment arms hold the wheelchair immovably on the platform when the user is exercising. The arm is split into two arm sections which rotate relative to one another through a third joint. The outer end of one of the arm sections is pivotally attached to the platform through a first joint and the outer end of the other arm section is pivotally attached to a clamp through a second joint. The clamp is configured to quickly and easily attach to the wheelchair frame. A clamp mechanism causes the first, second and third joints to be simultaneously locked immovably upon the activation of a single handle.
