  • Patent number: 11274260
    Abstract: A slide member is provided with a base material, a plated slide layer and an intermediate plated layer. The plated slide layer contains a solid lubricant. The intermediate plated layer is disposed between the base material and the plated slide layer, the intermediate plated layer increasing cohesion of the base material and the plated slide layer. The plated slide layer has a content of the solid lubricant in a range from 30 to 70 vol %, inclusive.
    Type: Grant

  • Patent number: 10605299
    Abstract: A bicycle control cable is provided with a central wire and at least one resin string. The at least one string made of resin is spirally wound onto the radially outermost surface in a direction intersecting with a center longitudinal axis of the central wire with a pitch less than or equal to 1 millimeter. The at least one resin string defines a spiral gap between adjacent windings of the at least one resin string. The at least one resin string defines an outer sliding surface for reducing a sliding resistance of the central wire. The central wire and the at least one resin string define an inner wire configured to slidably move in an axial direction with respect to the center longitudinal axis of the central wire within an outer case to operate a bicycle component.

  • Patent number: 9829035
    Abstract: A bicycle control cable is provided with a central wire, an outer case and a radial protrusion. The central wire includes at least one metallic strand defining a radially outermost surface of the central wire. The outer case surrounds at least a portion of an axial length of the central wire. The outer case has a radially innermost surface. The radial protrusion spirally extends along one of either the radially outermost surface of the central wire or the radially innermost surface of the outer case in a direction intersecting with a center longitudinal axis of the bicycle control cable. The radial protrusion reduces a sliding resistance of the central wire relative to the outer case. The central wire is configured and arranged to slidably move in an axial direction with respect to the center longitudinal axis of the bicycle control cable within the outer case to operate a bicycle component.

  • Publication number: 20140109716
    Abstract: A bicycle control cable includes a plurality of strands a forming a wire and an organic coating film. The wire has an outer periphery. The organic coating film is disposed on the outer periphery of the strands. The organic coating film has a graduated degree of polymerization that becomes higher as the coating film approaches the strands.
