Process and device for measuring and adjusting the angular movement of a fastening cleat on a clipless pedal
First Claim
1. A process for measuring and adjusting an angular position of a fastening cleat (1) of a shoe of a cyclist (2) on a clipless pedal (3), comprising the steps of:
- a) fixing said fastening cleat (1) in an approximate angular position under said shoe of the cyclist (2) and fastening said fastening cleat to said clipless pedal (3);
b) providing free angular movement of said fastening cleat (1) around an essentially vertical pivoting axis (A-A) during pedaling;
c) determining a range (α
) of said free angular movement;
d) measuring variations of a value of said free angular movement over time during pedaling;
e) calculating an average of the variations of the value of said free angular movement; and
f) adjusting said angular position of said fastening cleat (1) so that said average of the variations of the value of said free angular movement is brought to a median of said range (α
) of said free angular movement.

Abstract
A method and device for measuring and adjusting the angular movement of a fastening cleat on a clipless pedal, includes a motion detector which is fixed to the pedal to detect any angular movement in relation to the fastening cleat and transmit data to a data-processing device which calculates values of the angular movement as a function of time, and the average of the variations in the angular movement. The contactless motion detector includes a magnetic sensor which is fixed to the pedal, and is disposed facing a magnet that is fixed beneath the cleat and can detect any variation in the orientation of the magnetic field as a function of the angular movement of the cleat. The angular position of the fastening cleat is adjusted such that the average variation in the value of the free angular movement is returned to the median of the free angular movement range.
