ABSTRACT:
The mechanical control comprises a pedal (10) pivotally mounted on a fixed shaft (12), a cable (26) having one first end (25) connected to a receiver (34) and the second end (27) connected to the pedal (10) by means of a transmission device, the transmission device comprising a force-transmitting element (22) pivotally mounted on the fixed shaft (12) and on an outer cylindrical surface (40) of which the cable (26) is wound, a locking system causing the force-transmitting element (22), the cable (26) and the pedal (10) to be connected for rotation when the latter pivots from its rest position by an angle greater than a predetermined minimum angle .alpha.m, a spring (56) being disposed between the second end (27) of the cable and the pedal (10) for tensioning the cable (26). The locking system acts by catching the cable (26) between a first catching surface (42) formed on the force-transmitting element (22) and a second catching surface (44) formed on the pedal (10).
The mechanical control is more particularly intended for cable control of a receiver comprising friction members liable to become progressively worn with use of this receiver and also including resilient return means exerting a force which the mechanical control must overcome to actuate the receiver.
