Bicycle brakes

摘要

The operating lever (4) of a conventional hand brake, for front and rear wheels, is modified so that simultaneous action of lever and actuator head (2) activates a locking mechanism (3,6) which, in turn, arrests the lever (4). When the lever, and thus the head, are released, the respective wheel remains braked. The locking mechanism can only be cancelled by a repeat operation of the lever so it returns to its initial setting and, in so doing, returns the wheel to its normal function. A ratchet mechanism, between lever and its bearing block, can be actuated when the bicycle is parked, and is similarly released by renewed action of the brake lever. The mechanism makes use of a clamping screw to arrest the brake cable and, so, prevent it running back. An additional lock provided to guard against theft etc.
