  • Parking brake operating device
    Patent number: 4311060
    Abstract: An automotive parking brake operating device in which, when the brake handle is pulled up a locking mechanism which moves with the brake handle rotates a rotating member to wind the brake cable around the winding portion of the rotating member, and when the brake handle is lowered the rotating member is kept locked by another locking mechanism. By repeating the above operation of the brake handle, the rotating member is intermittently rotated until necessary length of the brake cable is wound up to effect firm locking of the parking brake. In disengaging the brake, the cable is loosened by turning the rotating member in the reverse direction by combined operation of the locking mechanism and the brake handle.
