Abstract:
A hand brake control mechanism installed in a wheeled apparatus for controlling the operation of a brake cable of the wheeled apparatus, comprising:a mounting base, said mounting base comprising a coupling portion coupled to a part of the wheeled apparatus, an open chamber, and a stop block disposed inside said open chamber;an operation handle pivoted to said mounting base, said operation handle comprising a front end inserted into said open chamber, a front end edge at the front end, and two parallel lugs forwardly extended from the front end, said parallel lugs each comprising an elongated sliding slot, and a front notch;a pivot inserted and mounted in the open chamber in said mounting base and inserted through the sliding slots on said lugs of said operation handle;an actuating bar turned about said pivot in said open chamber between the lugs of said operation handle, said actuating bar having a brake cable mounting portion disposed at one end and connected to the brake cable in the wheeled apparatus; anda link, said link having a first end pivoted to said stop block inside said mounting base, a second end, and two projecting rods bilaterally extended from said second end for engaging into the front notches on the lugs of said operation handle;wherein said operation handle can be moved relative to said mounting base between a first position, a second position, and a third position; said operation handle is disposed in said second position and the brake cable does no work when said operation handle receives no applied force; when an applied force is given to said operation handle to move said operation handle to said first position, said actuating bar is moved by said operation handle to pull up the brake cable, and the brake cable is released upon disappearance of the applied force from said operation handle; when said operation handle is moved by an applied force to said third position, the projecting rods of said link are forced upwards by the front notches of the lugs of said operation handle, causing the brake cable mounting portion of said actuating bar to hold the brake cable in a continuously braking status, and keeping the brake cable to be maintained in the braking status after disappearance of the applied force from said operation handle.
