  • Patent number: 9238932
    Abstract: A slide member for use in an automotive vehicle. The slide apparatus includes a first slide member having a slidably contacting surface. Additionally, a second slide member is provided having a slidably contacting surface which is in slidable contact with the slidably contacting surface of the first slide member. In this slide apparatus, at least one of the slidably contacting surfaces of the first and second slide members is formed of a transferable water repellent material having a water repellency and a sufficient transferability to form a transferred film of the transferable water repellent material on at least the other slidably contacting surface.
    Type: Grant

  • Patent number: 6030307
    Abstract: A rear derailleur for a bicycle includes a base member for fixing to a bicycle frame, a movable member for supporting a chain guide, and a linkage mechanism coupling the base member to the movable member so that the movable member is capable of movement relative to the base member. A roller is coupled to the base member for rotation about a rotation axis, wherein the roller includes a cable guiding surface for guiding an inner wire of a control cable. A casing support is provided for supporting an outer casing of the control cable, and a pivot coupling pivotally supports the casing support to the base member so that the casing support pivots around a pivot axis that is spaced apart from the rotation axis.

  • Patent number: 5860880
    Abstract: A rear derailleur for a bicycle includes a base member for attaching the derailleur to the bicycle, a movable member for supporting a chain guide, a linkage mechanism coupling the base member to the movable member so that the movable member is capable of movement relative to the base member, a biasing mechanism for biasing the movable member toward a wheel of the bicycle, and an actuating member for coupling to a control cable of the type having an inner wire that slides within an outer casing so that pulling the inner wire causes the movable member to move away from the rear wheel of the bicycle against the biasing of the biasing mechanism and releasing the control cable causes the movable member to move toward the rear wheel of the bicycle in accordance with the biasing of the biasing mechanism.

  • Patent number: 5622083
    Abstract: The present invention includes a disk shaped base member which has a notched central aperture extending therethrough and a cable shield retaining portion. A shaft member is formed with notched ends, one end of the shaft member extending thought the notched central aperture. A gear member is formed with gear teeth on an inner circumferencial surface and a notched central aperture. The other end of the shaft member extends into the gear member notched central aperture and is fixed thereto. The gear member and the base member confine a lever handle therebetween, but allow the lever handle to rotate. A pawl member retained within a recess in the lever handle, engages the gear teeth on the gear member restricting movement of the lever handle to predetermined arcuate steps.
