Abstract: Torsional stress of a cyclist's leg is minimized by providing spaced limit surfaces on opposing parts of a cycle pedal and a shoe cleat that are designed for step-in, twist-out engagement. Floating adjusters, in the form of threaded rods, are rotated to select the effective width of spaces between the spaced limit surfaces. The full width of the space allows full floating rotation of the cleat relative to the pedal, whereas adjustment of the rods selects smaller floating rotating of the cleat relative to the pedal. The spaced limit surfaces and the rods are provided in LOOK and SAMPSON types of step-in, twist-out pedals.

Abstract: A bicycle pedal system which attaches a cyclist's shoe to a bicycle pedal. The system consists of a cleat attached to the cyclist's shoe under the ball area of the foot. The cleat has two downward projections. These projections feature arcuate tracts for matingly engaging the cleat to a pedal body. The pedal body is shaped to matingly engage the cleat and contains a tensioned mechanism centered in the back of the pedal body. If a rotating force on the cleat exceeds a predetermined level, a release of the shoe cleat from the pedal body occurs. If such rotating forces do not exceed said predetermined level, the shock or movement will be absorbed and the shoe cleat is returned to the optimum position in the center of the pedal body.

Abstract: A pedal system equipped with braking apparatus which inhibits rotation of a pedal body about an axle when the pedal body is not engaged with the shoe of a cyclist. The brake system is released to permit normal pedal rotation when the shoe of a cyclist engages with the pedal body.
