Fixed Brake Patents (Class 188/84)
  • Patent number: 7891472
    Abstract: A protruding portion is formed integrally on an outer ring in such a manner as to protrude from an outer raceway surface toward an inner raceway surface. A sliding portion is formed on an inner ring as a separate element from the inner raceway surface in such a manner as to protrude from the inner raceway surface toward the outer raceway surface. Due to the sliding portion being brought into contact with the protruding portion during a relative rotation of the inner ring and the outer ring, the sliding portion is formed by applying an elastic material such as rubber to the inner raceway surface by heating or bonding.

  • Publication number: 20070235269
    Abstract: A motion-restraint arrangement (48) with elongate lines of elements (10), wherein each line of elements (10) has a number of individual elements (12) which can be erected by spring elements (20) from a small-volume thin storage condition into a large-volume active condition. Each respective individual element (12) has flexible lateral edge elements (16, 18), which in the active condition define a parallelepiped. The spring elements (20) extend in spatially diagonal relationship between the corners (22) of the respective parallelepiped (14). A motion-restraint arrangement (48) which is easy and inexpensive to produce and which has optimum restraint properties is obtained in that the spatially diagonal spring elements (20) are formed by spring wires (24), which extend in a zigzag shape in the longitudinal direction of the respective line of elements (10).

  • Patent number: 6422357
    Abstract: A braking apparatus for imparting constant mechanical torque to effect a braking action is capable of operating in a constant, smooth, and adjustable manner, yet operates essentially independent of friction and temperature, as well as independent of rotational speed. The braking apparatus includes a hub assembly having a hub, a collar, a plurality of torsional springs, a spring cap, a spring bushing, and damping means, and a sprocket assembly having a sprocket, a hub bearing, a retaining ring, and a plurality of roller assemblies each of which has a roller. The sprocket assembly is rotatably connected to the hub assembly by a hub assembly spring, a sprocket assembly spring, an adjustment cap, and an adjustment means. The apparatus provides braking by releasably contacting at least one of each of the rollers with at least one of each of the torsional springs so as to deflect and then release the torsional spring as the sprocket assembly rotates about the hub assembly.

  • Patent number: 5388673
    Abstract: A hand-held braking device for use with foot-mounted wheeled vehicles such as in-line skates, rollerskates, skateboards, roller skis, and other similar wheeled vehicles designed to control speed or to stop quickly in a short distance. The device consists of a pole whose length is approximately 90% of the height of the user. The top end has a handle; the center has a foam rubber hand grip; the bottom end has a brake pad assembly. The brake pad assembly comprises a front and a back trapezoid plate fastened to the bottom end of the pole, between which is fastened a replacable trapezoid pad of rubber or similar material, The rubber pad is approximately twice as large as the two plates and extends below the lower edges of the two plates. The rubber pad and the two plates are both curved to form a scoop, The bottom 6 to 8 inches of the pole is bent in a curve at approximately a 20' angle to the upper end of the pole.

  • Patent number: 4807727
    Abstract: Method and apparatus for securing an electric brake/clutch (14) against rotation relative to a stationary member (10). A preferred system includes an anti-rotation lever (26) attached to and extending from a brake/clutch housing (16). Anti-rotation lever (26) includes a flange (32) at its free end. Flange (32) is situated between a pair of spaced opposed rubber bumpers (34) attached to stationary member (10). Thus, torque applied to the housing (16) of brake/clutch (14) is transmitted through anti-rotation lever (26), rubber bumper (34), and ultimately to stationary member (10). The distance between rubber bumpers (34) exceeds the thickness of flange (32), whereby anti-rotation lever (26) and housing (16) can radially float relative to stationary member (10), thereby permitting "runout" of brake/clutch assembly (14).

  • Patent number: 4799576
    Abstract: A protective device for use on a wheeled vehicle such as a tractor pulled trailer equipped with an air brake is provided. The air brake includes a housing generally disposed lengthwise of the trailer and comprises a transversely disposed diaphragm in a medial portion thereof with air pressure communicating with the front side of the diaphragm and further comprises a heavy coiled spring positioned in opposition to the air pressure on the rear side of the diaphragm. A protective device in the form of a perforated plate is mounted adjacent to and rearwardly of the housing so as to be in the path of the coiled spring in the event of rupturing of the housing, as from corrosion, and releasement of the spring therefrom, to prevent the spring from being projected rearwardly away from the housing.

  • Patent number: 4582188
    Abstract: The speed of a pallet as it descends down a pair of inclined rails in a flow rack is controlled by a series of speed-control wheels mounted on axles fastened to frame members located underneath the pallet. A tapered roller bearing is interposed between each axle and wheel to mount the wheel for combined rotary motion and axial motion. Brake pads are mounted on the frame member for engaging a braking surface on the wheel as it moves axially in response to the pallet load. The brake pads apply friction to the wheel for slowing the speed of the pallet. A bar is provided adjacent the lower end of each rail for engaging the speed control wheels on the pallets to increase the axial pressure thereon and to increase friction for arresting the pallets and separating the same.

  • Patent number: 4537415
    Abstract: To substantially reduce the physical effort required to slow or stop a manually propelled wheelchair, the customary propulsion ring attached to the outer side of each main chair wheel is mounted on the wheel for limited inward axial movement under manual pressure and is biased outwardly by spring force. A brake ring of similar diameter near the interior side of each wheel in a plane parallel to the plane occupied by the propulsion ring is connected directly with the propulsion ring. An opposing friction brake shoe attached to the chair frame is engaged by the brake ring to slow or stop the chair whenever the chair occupant pushes the propulsion ring axially inwardly.
