Abstract
A friction braking mechanism for a merchandise cart or the like for holding objects includes a frame for supporting the container, and a plurality of wheels rotatably supported on the frame. The wheels are supported for rotation relative to the frame about a rotational axis. At least one of the wheels has a thread guard associated therewith and secured against rotation therewith. An arrangement which is continuously operable during rotation of the wheel coacts between the wheel and the thread guard for frictionally retarding rotation of the wheel. An adjustment arrangement is also provided for adjusting the amount by which the rotation of the wheel is frictionally retarded.
