Bicycle pedal and shoe having mating stepped surfaces

摘要

A bicycle pedal is mounted on a spindle secured to a crank arm. A pedal platform has a stepped upper surface. A cycling shoe is provided with a cleat section extending under the ball area of the cyclist's foot. The cleat section is provided with a stepped surface that is complementary with the stepped surface of the pedal. These complementary stepped surfaces include risers and steps that interlock or matingly engage when the shoe is pressed downwardly onto the pedal. When the risers of the shoe and the pedal matingly engage, they permit rearward and downward thrust of the shoe against the pedal to rotate the crank arm in the customary direction for driving a chain of the bicycle. Apertures provided in the pedal between the risers permit debris from the stepped surface of the shoe to fall through the pedal and not interfere with the mating engagement of the pedal with the shoe. A scraper blade secured to the rear of the pedal allows a cyclist wearing a cycling show to scrape the show clean and to otherwise additionally engage the shoe to the pedal to assist in rotating the crank arm.
