| Abstract: |
A simple, lightweight, easily assemblable, disassemblable and transportable frame and motive means which can be attached to a wheelchair to enable a user having a lower body disability to safely move to and from a standing position without assistance from another person. The device provides braces against horizontal movement of the user's knees and hips when standing to allow the individual's skeletal structure to support the majority of the individual's body weight. The device utilizes a manually operated worm gear mechanism to provide a mechanical advantage in lifting and security against undesirable reverse movement of the lifting means when under load.
