| 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 predetermiend 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.

I claim:
1. A bicycle pedal system comprising:
- a shoe cleat adapted to be affixed to a shoe of a cyclist,
- a front and a rear downwardly extending projection of said cleat,
- a pedal body adapted to be connected to a shaft on a bicycle crank arm,
- an arcuate forward extremity on said pedal body,
- an inner rear facing vertical surface on said front projection of said cleat,
- an arcuate channel in said rear facing vertical surface of said cleat,
- means for matingly engaging said arcuate channel of said inner rear facing vertical surface of said cleat with said arcuate forward extremity of said pedal body by inserting said arcuate forward extremity into said channel,
- an arcuate rear extremity of said pedal body,
- an arcuate rear facing vertical surface on said rear extremity of said pedal body,
- a spring loaded detent element projecting outwardly from said arcuate rear facing vertical surface of said body in a horizontal plane below the horizontal plane of a top surface of said pedal body,
- means including said detent element responsive solely to a downward movement of said rear projection of said cleat for matingly engaging said arcuate rear extremity of said pedal body with said rear projection of said cleat in an interlocked manner whereby pedaling forces may be applied to said pedal body by said cleat in an upward, downward, forward and backward direction with respect to the longitudinal axis of said bicycle, and
- means for controllably disengaging said cleat and said pedal body in response to a torsional force on said cleat in excess of a predetermined amount that is unrelated to the pedaling force that can be accommodated by said cleat and said body.
