In-line roller skate wheel assembly
First Claim
1. An in-line roller skate wheel, comprising:
- a wheel hub having;
(a) a hub core including a central axle bore formed along a wheel axis;
(b) substantially cylindrical tire receiving shoulders concentric with the bore;
(c) a tapered tire deflection controlling rim extending circumferentially about the shoulders and having rim side walls extending radially outward and tapering from a wide base at the shoulders to a narrow continuous and unbroken peripheral surface; and
an annular resilient tire mounted to the wheel hub, engaging the tire receiving shoulders and encasing the tapered tire deflection controlling rim.

Abstract
An in-line roller skate wheel and truck are described in which an elongated truck frame with a pair of spaced longitudinal side rails mount a plurality of roller wheels. At least one of the roller wheels has a hub core with a coaxial tire receiving shoulder. A tapered tire deflection controlling rim extends circumferentially about the shoulder, with rim side walls extending radially outward from a wide base at the tire receiving shoulder to a narrow peripheral surface. An annular resilient tire is mounted to the hub, engaging the tire receiving shoulder and encasing the tapered tire deflection controlling rim. The tire includes an annular ground engaging surface section and an annular high friction shoulder situated radially inward and axially outward of the ground engaging outer surface. The rim and tire configuration aid in maximizing speed and control in turns. Another one of the in-line roller wheels, situated at the heel end of the truck includes a tire of a slightly reduced diameter and is formed of a resilient material with a hardness value greater than the remaining tires on the truck. It also includes recessed braking dimples on its ground engaging surface to aid in approximating heels-forward "skid" stopping in a manner similar to stopping methods used by ice skaters.

12. An in-line roller skate wheel, comprising:
-
a hub formed about a central rotational axis; a tire body of a resilient material formed over the hub for rotation with the hub about the central rotational axis; said tire body including an annular ground engaging outer surface, and an annular high friction side shoulders spaced radially inward of and projecting axially from the ground engaging outer surface; said high friction side shoulders intersecting in a non-tangential manner with the annular ground engaging outer surface and being substantially frusto-conical and angularly inclined with respect to the rotational axis; whereby the annular ground engaging outer surface will roll against a support surface with the central rotational axis substantially parallel to the support surface, and the annular ground engaging outer surface and one of the annular high friction side shoulders will roll against the support surface with the central rotational axis tilted with respect to the support surface. - View Dependent Claims (13, 14)
