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.
Claims16
Device for fixing a shoe on a pedal of a pedal-powered machine such as a bicycle, comprising in combination:
- (a) a sole plate to be fixed to the sole of a cyclist's shoe and having forwardly and rearwardly facing transverse bearing surfaces at the front and rear of the plate comprising frontal forward stop means and a rearward surface;
- (b) restraining means mounted on the pedal and comprising on one hand frontal stop means adapted to be associated with those of the sole plate for restraining the sole plate in the forward direction, and, on the other hand, a transversely extending hook section on the pedal combined with a lip provided on said sole plate for restraining said plate in the upward direction, said frontal forward stop means of said sole plate being engageable against the frontal stop means of the pedal when the shoe is attached to said pedal;
- (c) holding means movably mounted on the pedal;
- (d) resilient biasing means capable of urging said holding means against the back of said rearward surface of the sole plate for opposing rearward displacement of the said sole plate when the rearward force on the shoe remains below a predetermined threshold value and for allowing said displacement when said threshold is at least attained;
- said frontal forward stop means and said rearward surface of the sole plate extending transversely under the sole of the shoe when said sole plate is fixed to the shoe sole, behind the portion of the sole having the greatest width, and said frontal stop means and said hook section of the pedal associated with said frontal stop means of the sole plate extending transversely over the major part of the width of the pedal and being fixed on the pedal behind the geometric axis of rotation of the pedal, said pedal including a portion which extends in front of said frontal stop means of said pedal, on which said portion the shoe is supportable substantially thereabove.
In a device for fixing a shoe on a pedal of a pedal powered machine such as a bicycle, said pedal having a spindle, and said device being of the type comprising:
- a sole plate to be fixed to the sole of the shoe and comprising forward stop means and a catch having a rearward surface;
- restraining means mounted on the pedal and comprising frontal stop means associated with the stop means and catch of the sole plate for restraining the sole plate against forward and upward movement relative to the pedal;
- holding means on the pedal;
- means mounting said holding means movably on the pedal;
- elastic biasing means biasing said holding means against the rear surface of the sole plate for opposing rearward displacement of said plate relative to the pedal when the rearward force exerted on the shoe remains below a predetermined threshold, and for allowing rearward displacement when at least said threshold is reached;
- the improvement wherein,
- said elastic biasing means comprises two torsion coil springs mounted side by side around a common transverse pin connected to the rear of the pedal and parallel to the pedal spindle, said holding means comprises a transverse strip parallel to the pedal spindle and having two lateral ends which are downardly folded and coupled respectively to said two torsion springs, said strip extending transversely over a major part of the width of the pedal and being engageable with a rearward surface of the sole plate, said torsion coil springs acting respectively on said lateral ends of the strip so that during transverse turning of the shoe in relation to the pedal, said catch of the sole plate, which bears against the associated frontal stop means of the pedal, turns transversely by urging the strip essentially against a single one of said torsion coil springs, and during rearward traction of the shoe, movement of the strip is resisted by both of said torsion coil springs.
