Adaptive physical education device

Image Number 10 for United States Patent #6004233.

An adaptive physical education device has a spring-back assembly with a U shaped frame that is positioned over first and second vertical posts. The spring-back assembly has a webbing attached by springs to a webbing frame, which is pivotally attached to the U shaped frame. The spring-back assembly is pivotable to different angles so that a ball may be caught and tossed at a variety of angles. In a separate embodiment, the webbing frame is removed and replaced with a ball catapult assembly, which is attached to the U shaped frame with elastic cords. The ball catapult assembly has a ball holder and a handle. A ball is placed in the ball holder, then a wheelchair bound participant pulls back the handle to apply tension to the elastic cords. The handle is released to propel the ball.
