  • Brake control device for a wheeled walker
    Patent number: 6032765
    Abstract: A brake control device is mounted on a handle of a walking frame used by a lame or elderly person as an aid in walking. The device includes a seat fastened at one end thereof with the handle, and a control handlebar fastened at one end thereof with the seat. The seat is provided with a control arm and a stop member. The control arm is fastened with the control handlebar and is connected with one end of a brake cable. The control arm is actuated by the control handlebar to swivel so as to pull the brake cable to bring about the braking action which can be sustained without having to keep holding the control handlebar. The control handlebar is made stationary temporarily by a rolling rod which is forced into a retaining recess of the stop member for sustaining the braking action.
