Abstract
Abstract The fixing device comprises a sole plate fixed to the sole of a cyclist's shoe and comprising forward stop means towards the front and a catch towards the rear. Restraining means mounted on the pedal comprise forward stop means associated with those of the plate, and a holding element movably mounted on the pedal and capable of being applied by elastic biasing means against the rear of said catch. The forward stop means and the catch of the sole plate extend transversely under the sole of the shoe, behind the sole portion having the greatest width, while the associated forward stop means mounted on the pedal extend transversely and are fixed on the pedal behind the pedal spindle.

Claim 4
Dependent Claim
45 words
A device according to claim 1, wherein the longitudinal distance between the frontal stop means of the pedal and said holding means is small in relation to the dimension of the pedal measured longitudinally in relation to the bicycle to which the pedal is fitted.
Claim 5
Dependent Claim
85 words
A device according to claim 1, wherein the rearwardly facing transverse bearing surface of the sole plate has, in its upper portion next to the shoe, a surface situated in a substantially vertical plane when the shoe is fixed on the horizontal pedal, and wherein said holding means bears against said substantially vertical surface to ensure the cooperation of the hook section and of the lip, whereas in its lower portion said transverse bearing surface has a cam surface which is inclined forwardly and downwardly.
Claim 6
Dependent Claim
40 words
A device according to claim 1, in which the width of the frontal stop means of the pedal is greater than the width of sole plate, so that the cyclist has scope for displacing his foot and his shoe laterally.
