ABSTRACT:
Upper and lower coupling members are provided to couple a shoe to a bicycle pedal. The lower coupling member has a central, generally circular recess. The upper coupling member has a boss depending from its lower surface to engage in the recess. The upper coupling member is secured by screws to the cyclist's shoe. A pair of lengths of spring wire form part of an M-shaped spring secured in the lower coupling member. The boss has a pair of horizontally extending grooves into which the spring lengths snap to latch the coupling members together. A pair of abutments in the recess coact with a pair of flat sides on the boss to limit heel-in shoe movement to an arc insufficient to unlatch the wire lengths from the grooves. In a heel-out rotary direction, however, the boss can turn in the recess through an arc sufficient for the lengths of spring wire to come out of the grooves so that the coupling members can become disengaged by a lifting force on the shoe.
