The invention relates to a brake and to a method for controlling the brake. The brake comprises a base part, a braking piece movably supported on the base part, which braking piece is configured to be moved between a braking position and a releasing position, a spring, with the spring force of which the braking piece can be dropped into a braking position, a support member for limiting the initial position of the drop-out movement of the braking piece and also a controllable actuator, which is mechanically connected to the aforementioned support member and configured to displace the initial position of the drop-out movement of the braking piece with respect to the braking position.

Brake mechanisms for a wheel of non-motorized wheeled vehicle such as, e.g., a shopping cart, are described. In various embodiments, the brake mechanism can provide a variable amount of braking force or torque between zero and an amount sufficient to lock the wheel. In some embodiments, the brake mechanism includes a brake plate that is movable toward and away from a surface of the wheel hub along a direction parallel to the rotation axis of the wheel. The brake plate is configured not to rotate when the wheel and hub are rotating. Frictional engagement between the brake plate and the surface of the wheel hub provides the braking force. The brake plate and/or the surface of the wheel hub can include engagement features such as, e.g., protrusions and slots. In some embodiments, the brake mechanism fits entirely within the wheel.

A tire chock with improved ease of use and prevention of theft. A threaded rod expands a scissor frame to force foot plates against a tire. The scissor frame foot plates are pulled apart or pushed together so that the frame fits between the tires. A hand-adjustable, freely rotatable nut is on the lower end of the rod is tightened. A wrench is used to tighten a second nut on the upper end of the rod, and a lock member is secured over the second nut.

There is provided a brake assembly for a height-adjustable walker apparatus. The brake assembly includes a brake actuator, a wheel-engaging brake member and a brake cable assembly. The brake cable assembly includes a flexible, inner cable. The brake cable assembly includes a flexible, outer casing through which the inner cable extends and is moveable relative to. The inner cable has a first end coupled to the brake actuator and a second end coupled to the wheel-engaging brake member. The brake assembly includes a brake cable housing shaped to enclose a slack portion of the brake cable assembly.

A traveling apparatus includes a frame, a wheel body, a rotating shaft, and a brake assembly. The wheel body is rotatably arranged on the frame, and is configured to roll on a bearing surface. The rotating shaft is connected to the frame, and the brake assembly is rotatably arranged on the rotating shaft. On a rotation path of the brake assembly, the brake assembly has an idle position in which the brake assembly defines a gap with a working surface of the wheel body, and a brake position in which the brake assembly is configured to be in contact with the working surface of the wheel body. The working surface is a surface of the wheel body configured to be in contact with the bearing surface.
