Definitions

  • the present invention generally relates to bicycle shoes for clipless pedals. More specifically, the present invention is related to a bicycle shoe with a cleat fixedly coupled to the sole of the bicycle shoe, particularly a shoe suitable for use with a low profile bicycle pedal and cleat assembly as disclosed in EP 0,826,588A.
  • bicycle pedals have been designed for specific purposes such as for pleasure, off road biking, road racing, etc.
  • One particular type of bicycle pedal which is gaining more popularity is the step-in or clipless pedal which releasably engages a cleat secured to the sole of a cyclist's shoe.
  • the rider steps onto the pedal and a clamping mechanism automatically grips on to the cleat secured to the bottom of the cyclist's shoe.
  • a tension mechanism is usually provided in the pedal for adjusting the force required to release the shoe cleat from the step-in pedal.
  • the cyclist when attaching the cyclist's shoe to the step-in pedal through the cleat, the cyclist moves the shoe obliquely downwardly and forwardly relative to the pedal body such that the front end of the cleat engages a front hook or clamping member of the pedal body.
  • the cyclist places the rear end of the cleat in contact with a guide portion of the rear hook or clamping member of the pedal body. In this position, the cyclist presses the shoe downwardly against the pedal to cause the rear hook or clamping member to initially pivot rearwardly against the force of a spring to move the rear hook or clamping member to a cleat releasing position.
  • the rear end of the cleat then enters a position opposite a back face of the rear hook or clamping member. Then, the rear hook or clamping member returns under the force of a biasing member or spring so that the rear hook or clamping member engages the rear end of the cleat. This engagement fixes the cyclist's shoe to the pedal via the cleat.
  • step-in pedals When step-in pedals are used for road type bikes, the pedal is typically only provided with a single clamping assembly such that the cyclist's shoe can only be coupled to one of the two sides of the pedal.
  • Off road or mountain type bikes usually have a pair of clamping assemblies such that the cyclist's shoe can be clamped to either side of the pedal.
  • the present invention is directed to a bicycle shoe adapted to fixedly receive a cleat thereto for use with a bicycle pedal in accordance with Claim 1.
  • a preferred embodiment provides a bicycle shoe adapted to fixedly receive a cleat thereto for use with a bicycle pedal, comprising: a shoe sole portion having an inner surface facing the foot of the cyclist, an outer surface facing the pedal, a toe portion, a heel portion longitudinally spaced from the toe portion and a ball section located between the toe portion and the heel portion with first and second elongated attachment slots formed in the ball section which extend substantially parallel to each other in a substantially longitudinal direction between the toe portion and the heel portion, the first slot having a first longitudinal length and the second slot having a second longitudinal length which is longer than the first longitudinal length of the first slot, the first slot being laterally disposed relative to the second slot in the ball section with the first slot being located between first and second ends of the second slot.
