Description

BACKGROUND

Technical Field

This disclosure generally relates to a cleat adapter system. More specifically, the present disclosure relates to a cleat adapter system for adjustably attaching a cleat to a cycling shoe.

Background Information

Various types of cycling shoes are available to suit a rider's riding style (e.g., road riding or off-road riding. Many bicycles use step-in or clipless pedals, which are used with cycling shoes having a cleat attached to the bottom of the sole. The step-in or clipless pedal engages the cleat to releasably secured to the pedal to the sole of the cycling shoe. In particular, with this type of bicycle pedal, the rider steps onto the pedal, and a clamping mechanism automatically grips the cleat to secure the pedal to the cleat. When releasing the shoe from the pedal, the rider will typically turn the shoe about an axis perpendicular to the tread of the pedal. As a result of the pivoting action, the clamping mechanism releases the cleat from the sole. Typically, the position of the cleat on the sole can be adjusted by loosening two or more bolts that fasten the cleat to the sole. For example, a cycling shoe that has a cleat fastened to the sole is disclosed in U.S. Pat. No. 10,342,285, which is assigned to Shimano Inc.

The initial position for the cleat 30 is preferably set based on an initial position of the first connecting portion 22 relative to the sole 12 of the cycling shoe 10, and an initial position of the second connecting portion 24 relative to the sole 12 of the cycling shoe 10. Alternatively, the initial position for the cleat 30 can be set based on either the initial position of the first connecting portion 22 or the initial position of the second connecting portion 24. The initial position can be either a factory default position or a user set default position.
The target position can be adjusted based on prestored tables or prestored maps, which are preferably user adjustable. Alternatively, the target position can be adjusted based on a formula such as the lateral target position is adjusted two millimeters for each increase or decrease of twenty watts (W) of pedaling input power once the forward speed is over 20 kmph and the pedaling input power is greater than 200 W. Also, the target position can be adjusted in one direction based on one or move of the bicycle information and/or one or more of the user information. For example, the target position is adjusted so that the cleat 30 moves forward a predetermined amount relative to the sole 12 as pedaling force increases, and so that the cleat 30 moves backward a predetermined amount relative to the sole 12 as pedaling force decreases. In another example, the target position is adjusted so that the cleat 30 moves forward a predetermined amount relative to the sole 12 as cadence increases, and so that the cleat 30 moves backward a predetermined amount relative to the sole 12 as cadence decreases.
In another example, the target position is adjusted so that the cleat 30 is moved to a predetermined position based on the type of traveling surface as determined by the GPS coordinates. In particular, the target position can be different for paved roads, unpaved roads and off road.
Generally, the target positions are preferably set such that (1) there is no adjustment from the initial position at low speeds, for example, 2 kmph or less, (2) the cleat 30 is moved backward when traveling on level ground at a constant speed or a small acceleration, (3) the cleat 30 is moved forward when traveling uphill and with a high pedaling power, and (4) the cleat 30 is moved forward when traveling with a high acceleration.
The following tables show two examples of preset target positions based on a plurality of bicycle conditions.
