  • Patent number: 4735107
    Abstract: A pedal arrangement for releasable engagement between a cycle pedal and a cyclist's shoe wherein the pedal is provided with engagement members on a top surface thereof preferably in the form of upstanding lugs and, cooperating engagement members are provided in a lower surface of a cyclist's shoe preferably in the form of recessed rabbets, the lugs and rabbets interengaging one with the other, in a releasable manner. The pedal is also provided with a resilient retaining member which extends upwardly of the top surface of the pedal on one side thereof and is in the form of an elongate spring portion with an upwardly extending abutment member at one end thereof. In use, the spring portion and abutment member allow the shoe to be held in an engaged position relative to the pedal. A positive and predetermined movement of the shoe relative to the retaining member causes the retaining member to move out of position allowing the shoe to be released from engagement with the pedal.
