Mechanical control assembly

Claim 1

A mechanical control assembly for a receiver (34) of the type comprising engaging members (39) and resilient return means (35) exerting onto at least one of said members a force which the mechanical control assembly must overcome to acutate said receiver, said mechanical control assembly comprising: a pedal (10) adapted to rotatingly pivot on a fixed shaft (12) from and to a rest position; a cable (26) having a first end (25) adapted to be connected to said receiver (34) and a second end portion (27) connected to the pedal (10) by means of a transmission device, characterized in that said transmission device comprises a force-transmitting element (22) pivotally mounted on said fixed shaft (12) and having an outer cylindrical surface (40) onto which said cable (26) is partially wound; a spring means (56) disposed between said second end (27) of the cable and said pedal (10) for tensioning said cable (26); and a locking system causing said force-transmitting element (22), said cable (26) and said pedal (10) to be moved in unison when said pedal (10) pivots from said rest position by an angle greater than a predetermined minimum angle (αm), wherein said locking system acts by catching said cable (26) between a first cathcing surface (42) formed on said force-transmitting element (22) and a second catching surface (44) formed on said pedal (10), said second catching surface (44) cooperating with said first catching surface (42) through said cable (26) to rotate said force-transmitting element (22) to cause said cable to be pulled when said pedal pivots by an angle greater than said predetermined angle (αm).
