    Abstract: 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.

  • Patent number: 8925706
    Abstract: A vehicle parking brake control has an extendable pin with three faces, and a roller on a lower surface. The faces correspond to engage, hold, and disengage of a parking brake. The control also has a lever rotatably connected to it, where the lever has a roller at a lower lever surface. The roller being capable of rotational contact with the pin faces. Further, the control has a base with an upper surface for the pin roller to move across. When the parking brake is engaged the lever roller is in contact with a first face, when the brake is on hold the lever roller is in contact with a second face, and when the brake is in the disengage position the lever roller is in contact with a third face of the extendable pin. Consequently, the rollers provide a reliable lifelong operation of the control over prior controls.

  • Patent number: 8899638
    Abstract: The invention relates to a locking system for a rotatable part, in particular in arrangements in which two parts which can be rotated in relation to each other, for example a die and a punch in a stamping apparatus, have to be aligned exactly in relation to each other. In order to provide a positionally accurate mechanical locking system with a simple design, the invention proposes that a gearwheel (3) having an end-side and/or axially effective toothing system (4) is connected to the rotatable part (2) fixedly in terms of rotation, and that at least one toothing segment (5a-5f) which can move to and fro in the direction of the axis of rotation and/or parallel to the axis of rotation of the gearwheel is arranged over the circumference of the gearwheel, wherein the teeth or gaps between the teeth of the toothing segment and gearwheel can be brought into engagement without play.

  • Patent number: 8573368
    Abstract: A parking brake actuator system for an outdoor power equipment unit, such as a riding lawn mower, comprises a reversible electric motor that drives a gear reduction assembly. The gear reduction assembly rotates an output shaft at a speed slower than the speed of rotation of the motor. The output shaft has opposite ends that are linked by a pair of actuating rods to a pair of parking brakes. As the motor is rotated in reverse rotary directions, the connecting portions of the rods that are coupled to the parking brakes are moved in opposite, straight line directions to move the parking brakes between brake disengaged and brake engaged positions.
