<p>An exercise machine for use by a handicapped or impaired person from his wheelchair is disclosed which has a framework and wheelchair wheel-receiving ramps and cradle onto which the user may roll his chair. A set of rotatable hand cranks are interconnected by sprockets and a chain to a pair of orbitable pedal assemblies mounted on the frame. The pedal assemblies are provided with velcro-connection straps and weights so as to be self-orienting in an orientation that easily receives the user's feet, and means for releasably locking the pedal assemblies is provided. The latter is readily operable by the user so that he or she can rotate one of the pedal assemblies into an orbital position for easily inserting a foot, lock in that position, insert his foot, release the lock and using the hand cranks to move the other pedal assemblies into a convenient position, relock the mechanism and insert and fasten in place the other foot. The interconnected pedal-crank mechanism is mounted so that it can be easily pivoted on the framework so as to move from a convenient foot insertion position to a convenient exercise position; and user-operable means are provided for locking it in various pivotal positions. After exercise, the user may remove his feet from the machine by the same process of locking and rotating the pedal-hand crank and when this is done, move the wheelchair out of the cradle and ramps. The machine has the advantage that the user may enter, affix his feet, use, and remove his feet and exit without the need of assistance from anyone else.</p> |
