ABSTRACT:
An improved exercise device of the type attached to wheelchairs includes a frame having vertical and horizontal portions which support operatively connected, rotating handlebars and foot pedals for imparting movement to the arms and legs of a patient. The weight and height/length dimensions of the device are balanced with those dimensions of standard wheelchairs to create stability. The device further includes means for rendering the guide wheels of the chair stationary, and an improved lift mechanism for lifting or lowering the front wheels of the chair off/on the floor so that the device can be utilized in a stationary position or to drive the chair. The lift mechanism includes an externally threaded rod operatively mounted in an internally threaded shaft. A handle is attached to the upper end of the rod and a swivel-mounted rotation wheel or caster is mounted to the opposite end. Rotation of the handle and rod moves the caster into engagement with the floor and lifts the drive wheels of the exercise device off the floor thereby rendering the device and chair stationary.
