Definitions
- Such a pedal is previously known from international patent application having publication no. WO93/03955, which publication inter alia mentions a pedal type wherein a special shoe to be clicked into a fixed position and which has a stiff sole, constitutes a part of an elongate, stiff pedal, and wherein a freewheel bearing with a one-sense rotation block, in cooperation with the elongate pedal design, provides a possibility for applying additional driving torque about the crank axis in the upward pulling phase of the pedal motion.
- this advantageous combination effect is achieved by providing a bicycle pedal having a unidirectional rotation block for applying an additional torque about the bicycle crank axis from the bicyclist's heel part during the upward pulling phase, wherein the pedal which comprises a pedal housing and has a tread plate situated on top of the pedal in a use position, cooperates with a click attached bicycle shoe with a stiff sole to provide an additional moment arm about the crank axis.
- the bicycle pedal of the invention is characterized in that it contains a blocking member supported about a pivot which is fixed in the pedal housing and is parallel to the pedal axle and arranged at a distance in front thereof, in a use position, the tread plate being integral with the blocking member, and that the blocking member comprises an engagement part for providing blocking engagement with the pedal axle when the heel part produces an upward directed force.
- the pedal axle may have an externally arranged drum about which a flexible tension band lies in a loop, which tension band is adapted to enter into blocking friction engagement with the drum by tightening thereabout when an upward force is produced from the heel part so that the rear part of the blocking member is rotated up about the pivot.
- the pedal consists of a pedal housing a having bearing means for the axle b and room for a drum c which is rigidly attached to the axle b, e.g. by toothing.
- a blocking member is independently supported in the pedal housing a in such a manner that when it is lifted, it blocks against rotation in relation to the drum c, either by friction caused by a wedge effect between two opposed surfaces h and the drum c, fig. 1 , or by engagement between a toothing i in the blocking member d and a toothing j on drum c, fig. 2.
- the blocking member d can instead be implemented with a flexible tension band g, fig. 3, which is tightened when the blocking member d is lifted.
