Device for fixing a shoe to a bicycle pedal

摘要

The device for fixing a shoe to a bicycle pedal includes a plate which is fixed to the sole of the shoe and which has a front wing and a rear wing for the engagement of coupling elements which are associated with the pedal, the coupling elements being respectively constituted by a front fixed coupling element and by a rear movable coupling element which is biased forward by an elastic element in which a rotation of the sole about an axis perpendicular thereto causes the backward movement of the movable coupling element and its lateral disengagement from the pedal, due to the engagement of an inclined surface of a tooth of the rear wing with a corresponding inclined surface of the movable coupling element, and thereby the rear movable coupling element can slide in a straight line in a direction which is at right angles to the rotation axis of the pedal.
