Abstract
A polyurethane in-line roller skate wheel including a narrow hub mounting a polyurethane tire body having side walls curving axially inwardly from a major thickness to a minor thickness at the hub flange interface. In one embodiment, the hub is made of sections locked together by either adhesive or mechanical interlocks.
Claims16
A narrow light weight in-line quick turn roller skate wheel comprising:
- a relatively soft cast molded urethane tire body formed with an annular tread crown having radially inwardly and outwardly sloping side walls radiating axially outwardly to a maximum body width of 0.850 inches or less and then formed with a narrowing body section configured by such walls sloping radially and axially inwardly toward one another to a predetermined axial width, the body further formed with radially inwardly facing flanking beads;
- a hub including an annular housing formed with annular, radially outwardly facing support flanges supporting the respective beads and configured with a combined axial width corresponding with said predetermined width;
- and
- said hub being formed with a radial disk embedded in the body to facilitate anchoring thereof to such hub.

A narrow light weight quick turn in-line roller skate wheel comprising:
- a urethane tire body formed with a tread crown having radially inwardly and outwardly sloping side walls radiating axially outwardly to a maximum body width of 0.850 inches or less and then formed with a narrowing body section configured by such walls sloping radially and axially inwardly toward one another at a selected angle to a predetermined axial width, the body further formed with radially inwardly facing flanking beads;
- a hub including an annular housing formed with annular, radially outwardly facing support flanges supporting the respective said beads and configured with a combined axial width corresponding with said predetermined width, the support flanges terminating at the opposite axial ends angling radially and outwardly inwardly toward one another at said selected angle;
- and
- said hub being formed with a radial disk embedded in said body to facilitate anchoring thereof to such hub.

A narrow profile lightweight quick turn high performance quick turn in-line skate wheel comprising:
- a relatively soft cast molded, annular urethane tire body formed with an annular narrow tread crown and having side walls tapering radially inwardly and axially outwardly away from one another to a major thickness of 0.800 inches or less and then tapering radially and axially inwardly toward one another for a selected distance and turning axially inwardly to form respective radially inwardly facing tire beads;
- and
- a relatively hard hub including a radially outwardly projecting weight bearing support disk embedded in said tire body to cooperate in supporting said tire body against axially flexing, said hub further formed on its axially opposite side with axially outwardly projecting annular support flanges having radially outwardly facing bead support surfaces engaging the respective said tire body beads whereby loads applied to said hub will cause said tire body to flex and grip the underlying support surface and, as said wheel is inclined from the vertical under load said support disk will cooperate in supporting said tire body against axial deflection.
A narrow light weight quick turn in-line roller skate wheel comprising:
- a relatively soft cast molded tire body constructed of a mixture of polyurethane including prepolymers, curatives and pigment formed with a tread crown having radially inwardly and outwardly sloping side walls radiating axially outwardly to a maximum body width of 0.850 inches or less and then formed with a narrowing body section configured by such walls sloping radially and axially inwardly toward one another to a predetermined axial width, the body further formed with radially inwardly facing flanking beads;
- a relatively hard hub including an annular housing formed with annular, radially outwardly facing support flanges supporting the respective said beads and configured with a combined axial width corresponding with said predetermined width;
- and
- said hub being formed with a radial disk embedded in said body to facilitate anchoring thereof to said hub whereby, when loaded, the hub and disk will cooperate to support the tire body while the body flexes under load to grip a support surface.
