Abstract

A sports wheel chair has elongated side frame members of hollow high strength tubing extending along the two sides of the chair to provide rear wheel and seat support and extending accurately downwardly to provide front wheel supports. The elongation provides a degree of flexibility that permits front end collisions without damage and permits flexure to maintain contact of all four wheels with uneven terrain. Elongation of the frame increases stability and concentrates weight on the rear wheels for greater maneuverability. The main wheels are cambered out from top to bottom to protect the hands and provide a wider wheel base. All of the frame members are hollow tubes to impart light weight to the chair along with great strength. The two elongated side frame members are joined by novel strong quick connecting and disconnecting parts at the front and back to permit rapid disassembly without sacrificing strength. The front connecting part also provides a foot rest. The main wheels are secured to the frame by strong quick disconnect mechanisms for quick removal and replacement and a removable spoke shield is provided which is retained primarily by the hand wheel connectors. A canvas seat and back having Velcro connections provides ready removal and the ability to change seat angle and position of the seat and backrest.
