Abstract:
1. A detachable bicycle pedal mounting structure comprising: a crank having a screw hole at one end, a pedal having a shaft spindle equipped with a male thread, a solid plug connector having a male threaded portion at a first end, and a quick release manual connect coupling arranged along an axis of said crank screw hole, the male threaded portion at the first end of said plug connector being threaded into said screw hole of said crank, said plug connector adjacent the male threaded portion having a hexagonal cross section extending along a plug axis and reverting back to a smooth cylindrical shape with a locking indent annular groove created by reducing and restoring and reducing again the plug diameter along the plug axis, said plug connector interconnecting with the quick release manual connect coupling by manually pulling a spring activated slide sleeve of the coupling along said plug axis away from said crank, thereby permitting locking ball bearings within said coupling to move freely within said coupling into and out of the locking indent groove of the plug connector, and also permitting entrance and exit capability of the plug connector into and out of the coupling, said plug being locked into position by releasing the slide sleeve allowing spring tension to force said slide sleeve back along said plug axis toward said crank and to stop and hold at a retainer ring, said slide sleeve thereby forcing said ball bearings into a locking position within said coupling, said coupling thereby clasping the plug connector, said coupling having a female threaded hole being connected to the male threaded shaft spindle of the pedal thereby permitting the pedal to be detachable by means of manually pulling said coupling slide sleeve.
