Abstract
PURPOSE:To secure stable braking operation in case of emergency and obtain smooth operation of the brake, by making said braking operation to be ready whether the brake is alert or released, according to variation of the degree of stepping a pedal arm. CONSTITUTION:A pedal arm 4 and the operating arm 3 to which a brake cable 32 is connected are pivotally supported on the shaft 2 concentric to the sector teeth 11 and 12 of a base 1. The pin 42 projecting from the arm 4 is engaged with the elliptical hole 33 drilled in the circumferential direction on the operating arm 3. The arm 4 is urged counterclockwise by a spring 43. The latchet member 5 which can be engaged with the teeth 11 is pivotally installed at the other edge 34 of the operating arm 3, and a reversal mechanism 6 is installed. The reversal mechanism 6 consists of the main member 7 pivotally installed on the other edge part 34 and the pole member 8 pivotally installed on the main member 7. The main member 7 is connected to the latchet member 5 through a spring 37, and the pole member 8 is urged to a fixed position by a spring 81, and the latchet 82 on the top edge of the pole member 8 is engaged with the teeth 12.
