Quick release wheel mount

Abstract

An axle pin sized to fit in slidable supporting engagement within the wheel bearing of existing occupant actuated wheel chairs has a nut-like head and shoulder on one end that abuts the inner race of the bearing. An annular grove in the axle pin receives a snap ring abutting the opposite end of the bearing. The portion of the pin beyond the groove is sized to fit in close slidable relation within the axle receiving bore formed in an existing chair. The pin has a shoulder connected to an integral axially projecting end extending beyond the frame. A body member defines a bore receiving the projecting end of the pin. The body member has an integral externally threaded neck fitting around the pin and threads into the existing frame and abuts the shoulder on the pin. The body member defines an internally threaded transverse bore which intersects the pin receiving bore. A lock support member with a spring pressed lock pin therein is engagable in the bore in the body with the end of the lock pin projectable into an annular groove formed in the axle pin. A pull ring on the lock pin permits retraction of the lock pin to permit removal of the axle pin and the wheel as a unit.
