  • Patent number: 6453771
    Abstract: A bicycle pedal is provided with a pedal shaft or spindle, a pedal body with at least one cleat engagement mechanism and a tread cage supporting a rider's foot for attaching a shoe thereto via a cleat. The bicycle pedal body and the tread cage are coupled together for rotation about the pedal shaft or spindle. The tread cage is at least partially constructed of a resilient material to allow deflection of the tread cage relative to the pedal body. The tread cage has a tread surface that is at least partially located above the cleat engagement mechanism such that the tread cage must be deformed for complete engagement of the cleat with the cleat engagement mechanism. In other words, the resilient material of the tread cage permits limited angular rotation between the pedal body and the cage such that the tread surface contacts the shoe of the shoe when the cleat is in complete engagement with the cleat engagement mechanism.

  • Patent number: 6425304
    Abstract: An improved clipless pedal of the kind having forward and rearward cleat retainers configured to releasably secure the cleat of a rider's shoe and prevent an unintended release of the securement. The pedal includes a special wall/stop fixture that defines forward and rearward walls for preventing the cleat from moving forwardly or rearwardly relative to the pedal by an amount that otherwise would be sufficient to cause an unintended disengagement of the cleat from the pedal. These walls have no effect on the intended release of the cleat from the pedal, which is accomplished by rotating the shoe about an axis perpendicular to the pedal's upper face.
