| Abstract: |
To enable a cyclist to provide 360° of driving force on each bicycle pedal, the cyclist's shoe is formed with a pair of lugs that mate with receivers formed on a bicycle pedal. The shoe is connected and disconnected to the pedal by a simple edgewise movement, with the connection being arranged to maintain the shoe in driving relation with the pedal when pedaling force is applied. In an alternative construction, the male connecting lugs are formed on the pedal while the female receivers are formed on the shoe.

I claim:
1. The combination of a bicycle pedal, a shoe, and connector means formed on the pedal and the shoe for releasably connecting the shoe to the pedal in a manner to enable rotational force to be applied through the shoe to the pedal through 360° of rotation, said connector means including interengaging connectors arranged such that the shoe may be connected to and disconnected from the pedal simply by moving the shoe relative to the pedal wherein the connector means on the pedal are arranged so that the connectors define a concave curve on the surface of the pedal facing outwardly from the pedal's rotational axis, said curve being in the plane defined by the center of curve and the pedal's rotational axis, and the connector means on the shoe are arranged to define an outwardly facing convex curve which mates with the concave connector means on the pedal so that the normal bike pedaling action produces lateral force components tending to maintain the shoe centrally on the pedal throughout the entire 360° rotation of the pedal.
