  • Publication number: 20070034464
    Abstract: A shock absorber having a valve controlling the flow rate of fluid between a compression chamber and a rebound chamber in a housing and separated by a piston. The valve has an orifice component and a blocker component, one of which has a permanent magnet, and the other of which has a magnetically permeable material. Upon the application of sufficient fluid pressure, the blocker component is forced away from the orifice component, despite the magnetic bias that tends to attract the two structures. Because the magnetic force decreases as the two components are spaced farther apart, the shock absorber has excellent performance characteristics. Alternatively, a mechanical spring urges the blocker closed, and magnetic attraction between the blocker and a spaced opener mitigates the increased force of the compressed spring tending to close the valve.

  • Patent number: 4953425
    Abstract: A bicycle pedal attachment having an elongated strap that is diagonally arched and attached to the bicycle pedal such that the front end of the strap is secured adjacent the front inside edge of the pedal and the rear end of the strap is secured to the bicycle pedal adjacent its rear outside edge. The structure allows the bicyclist to insert his foot into the pedal attachment toe first and at a diagonal angle through the arched loop formed by the strap and then by pivoting his heel inwardly the foot of the bicyclist will be captured with tension applied to the front outside of the foot across the top of the foot and also to the inside of the foot.
