ABSTRACT:
Quick release mechanism which can be locked to prevent unauthorized removal of a bicycle wheel or other object secured thereby. The mechanism has an axially extending drawbar, a pair of clamping elements mounted on the drawbar for axial movement relative to each other between securing and released positions, an operating lever connected to the drawbar for moving the clamping elements between the securing and released positions, and a lock forming an integral part of the mechanism. In one embodiment, the operating lever is disconnected from the drawbar and locked in this position to prevent unauthorized removal of the object secured by the mechanism. In other embodiments, the operating lever is locked to prevent unauthorized release of the mechanism. A force indicating nut employed as one of the clamping elements indicates when the mechanism is adjusted for the proper tension to retain the mechanism in the secured position.
