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.

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.

A bicycle pedal system comprising: a shoe cleat adapted to be affixed to a shoe of a cyclist, a pedal body adapted to be connected to a shaft on a bicycle crank arm, a forward extension of said pedal body having a first longitudinal radius on its front extremity, a substantially flat horizontally oriented top portion of said cleat, a downwardly projecting front portion of said cleat affixed to said top portion, an arcuate channel on a rear facing vertical surface of said front portion of said cleat with said channel having a longitudinal radius equal to said first longitudinal radius, said channel further having a vertical radius, a downwardly projecting rear heel portion of said cleat affixed to said top portion and having an inner front facing vertical surface, an inner arcuate channel on said front facing vertical surface of said heel portion of said cleat with said last named channel having a longitudinal radius equal to said first longitudinal radius, a lower front surface of said heel portion of said cleat, a ridge on said lower front surface of said heel portion, an arcuate seating cavity in said channel of said heel portion with said cavity being deepest in the middle of said heel portion intermediate the sides of said heel portion and having a decreasing depth as each side of said heel portion is approached, said front extremity of said body being adapted to be inserted into and matingly engaged with said channel in said front portion of said cleat so that said front extremity engages in said front portion of said cleat, an arcuate rear extremity of said pedal body having a longitudinal radius equal to said first longitudinal radius, a spring loaded detent element normally protruding outward from a rear facing vertical surface of said rear extremity of said pedal body, a lip on said ridge for compressing said detent element inwardly after said forward extension of said body is matingly engaged with said channel in said front portion of said cleat and as said lip of said ridge in said heel portion of said cleat presses downward against said detent element, said detent element being adapted to clear said ridge and extend outwardly from said rear facing vertical surface of pedal body and enter said arcuate cavity in response to a further downward travel of the heel portion of said cleat with respect to said rear extremity of said pedal body, and said pedal body and said cleat being matingly engaged upon the outward extension of said detent element as it clears said ridge and enters said cavity, said rear facing surface of said body engaging in said channel in said heel portion when said body and said cleat are matingly engaged, said radii being effective to effect a disengagement of said cleat and said body in response to a torsional force on said cleat in excess of a predetermined amount with said torsional
