Technical Examples

A manually operable standing wheelchair includes an actuator for moving an occupant from a sitting position to a standing position. The manually operable standing wheelchair has a lifting mechanism including a ratchet, cable, pulley, and telescopic tubes, which the occupant may manually operate to shift from the sitting position to the standing position. There is also a drive system to enable the occupant to manually move himself or herself in and the wheelchair from the sitting position to the standing position, or in any position in between. The drive system may include adjustable lever drive arms with friction pads adapted for allowing the occupant to move in any position. The wheelchair is equipped with a set of spring loaded anti-tip wheels that automatically deploy when the manual wheelchair begins to lift from the sitting position to the standing position.
