ABSTRACT:
A quick release mechanism is provided having a drawbar with a camming lock positioned at one end and an end cap positioned at the opposing end. The camming lock includes an axle having a plurality of primary locking slots formed therein. The camming lock also includes a cam having a receiving chamber formed therein and a tongue radially projecting therefrom. A plurality of primary locking slots extend from the tongue to the receiving chamber. The receiving chamber is configured to receive the axle so that the cam can freely rotate relative to the axle and the primary locking slots can be aligned with the secondary locking slots. Selectively positioned within secondary locking slots are a series of pins and springs. When secondary locking slots and the primary locking slots are aligned, select pins extend therebetween, thereby preventing annular rotation of the cam relative to the axle. The quick release mechanism also includes a lever having a channel formed at one end with a series of key pins projecting therefrom. As the tongue is received within the channel, the key pins selectively position the pins within the cam to allow free rotation of the cam relative to the axle. By selectively rotating the cam relative to the axle using the lever, structure position between the camming lock and the end cap can be compressed along the drawbar.
