ABSTRACT:
The hand brake includes a main frame fixedly mounted on a handlebar of the walker, a control lever pivotally connected to the main frame, a brake member pivotally connected to the control lever to locate in a working space of the control lever, and a steel cable connected to the brake member. With changes in positions of the control lever, the brake member is caused to change its position in the working space of the control lever to pull the steel cable and thereby to either brake the wheeled walker, to brake and park the wheeled walker, or to return the walker to a non-brake state.
