    Abstract: A skate wheel for an in-line skate includes a skate wheel hub having an inner hub, an outer rim, and, extending therebetween, a plurality of blade-form spokes. A skate tire is mounted upon an outer surface of the outer rim of the skate wheel hub. Opposed surfaces of adjacent blade-form spokes, in cooperation with opposed surfaces of the inner hub and the outer rim, define airflow passageways through the skate wheel. Each blade-form spoke includes a radially-aligned first spoke-edge surface exposed at a skate wheel face, a radially aligned opposite, second spoke-edge surface exposed in a region of a center plane defined by the skate wheel, and a body extending smoothly between the first and second spoke-edge surfaces. Also described are in-line skates with skate wheels of the disclosure, and skate wheel hubs for such skates.

    Abstract: A skate wheel and method of making the same are provided. The skate wheel includes multiple materials of differing durometers disposed on an inner hub. First, a solid or microcellular urethane is seated on an outer rim of the hub in a ring configuration around the rim. A urethane tire material surrounds the ring. The outer tire material is constructed preferably of a urethane that is more durable and harder than the ring. The ring is made of a highly resilient urethane for high speed. A wheel also is provided with energy absorption to counter rough road surfaces with less loss of energy by the skater, while increasing the traction of the skate wheel on the surface. A method is also provided of making a wheel by pouring differing resins into a mold and either spinning or separating the resins while allowing their interfaces to cure together for bonding therebetween.

    Abstract: Disclosed is an in-line skate wheel that includes: (a) a braking portion including a high friction surface material having a hardness from about 75 to about 95 Shore A, and a coefficient of friction from about 0.45 to about 1.5; and (b) a skating portion including a low friction surface material having a hardness from about 75 to about 95 Shore A, and a coefficient of friction from about 0.1 to about 0.45. The skating portion includes a higher proportion of low friction surface material than the braking portion. The wheel delivers variable traction in response to the angle of wheel contact with the ground, without sacrificing a smooth ride or wheel durability. Utilizing the variable traction of the wheel a skater can stop safely and reliably, using known ice-skating maneuvers, wherein the wheel is turned away from the skater's direction of travel.
