The goal of this project was to facilitate the transfer of an eight-year-old student with cerebral palsy from her wheelchair to an existing standing assist device by designing an attachment for the standing device. The transfer to and from the standing device used to require two aids. A four-bar slider mechanism, driven by a linear actuator, was designed to rotate a frame from a position over her wheelchair to the standing device. The client is suspended from the crossbar of this frame in a quick to don and stable harness. Additionally, the transfer mechanism has a small footprint outside of the initial device, which was important for use in a public school. The mechanism functions with a light load, but is not ready for the client's use.
