Abstract:
A brake mechanism for a walker, essentially comprised of a brake disk fixed onto the side of a wheel of the walker, a brake base on the relative side of the wheel frame, a brake cable having its length longer than the linear distance between the brake base and a brake handle characterized by that the wheel fixed with the brake disk is pivoted to the wheel frame with a shaft, the brake base moving against the brake disk on the relative side of the wheel frame, an elastic member pushing against the brake base so that its bottom holds against the lower edge of the brake disk, the brake cable is fixed to the brake base with an outer wire at one end, an inner wire penetrates the brake base for it to be connected in position to the wheel frame, and another end of the brake cable is connected to a brake handle so that once the inner wire inside the brake cable is pulled as the brake handle is pulled, the outer wire is squeezed and compressed to create at another end a force of counter winding to cause the brake base moving downward for its bottom to clear away the lower edge of the brake disk, thus to release the brake to the wheel.
