1. A roller skate wheel for mounting from a roller skate axle and comprising:
- a pair of annular saucer-shaped hub rims formed with central openings for passage of said axle, including annular axially inwardly directed spacer lips cooperating to form a roller bearing gland surrounding said openings and radiating outwardly to form axially spaced apart hub rings cooperating to form therebetween a radially outwardly opening annulus, said rings being formed with a pattern of hub bores spaced equidistant thereabout, said rims projecting further radially outwardly to then flare axially outwardly away from one another to form tire seat flanges that cooperate in forming an annular tire seat;
an elastomeric annular tire formed with a radially outward tread surface and a radially inward facing bead surface configured to nest on said tire seat;
a mounting flange formed with a radially outer extent embedded in said tire and projecting radially inwardly to define a mounting ring for receipt in said annulus and including a pattern of mounting bores aligned with said hub bores; and
hub bolts for receipt in the respective said hub and mounting bores to fasten said hub rims together fixedly securing said hub rims to said mounting ring to thereby mechanically lock said tire to said hub rims to positively prevent relative rotation of said tire with respect to said rims.

Abstract
A skate wheel hub assembly incorporating confronting hub rims cooperating to form at their radial outer extremities a V-shaped tire seat. The tire seat supports an elastomeric tire having a rigid mounting ring projecting radially inwardly. The mounting ring is locked between the confronting rims to eliminate relative movement between the tire and the wheel hub. In one form, the bearing assemblies may be offset in staggered relation on alternating opposite sides of a longitudinal skate center line.

18. A roller skate wheel for mounting from a roller skate axle disposed perpendicular to a pair of longitudinal mounting rails spaced laterally apart equidistant on opposite sides of a longitudinal center plane and comprising:
-
a pair of annular saucer-shaped hub rims formed with central openings for passage of said axle, including annular axially inwardly directed spacer lips cooperating to form a roller bearing gland offset to a lateral side of said central plane surrounding said openings and radiating outwardly to form axially spaced apart hub rings cooperating to form therebetween a radially outwardly opening annulus, said rings being formed with a pattern of hub bores spaced equidistant thereabout, said rims projecting further radially outwardly to then flare axially outwardly away from one another to form tire seat flanges that cooperate in forming an annular tire seat; a bearing assembly in said bearing gland having an inner race for receipt on said axle, a plurality of ball bearings, and an outer race for carrying said pair of hub rims from said pair of rails such that, when loaded, said bearings are loaded at an opposite side of said longitudinal central plane to said lateral side; an elastomeric annular tire formed with a radially outward tread surface and a radially inward facing bead surface configured to nest on said tire seat; a mounting flange formed with a radially outer extent embedded in said tire and projecting radially inwardly to define a mounting ring for receipt in said annulus and including a pattern of mounting bores aligned with said hub bores; and hub bolts for receipt in the respective said hub and mounting bores to fasten said hub rims together fixedly securing said hub rims to said mounting ring to thereby mechanically lock said tire to said hub rims. - View Dependent Claims (19)

20. An in-line roller skate comprising:
-
a pair of longitudinal mounting rails spaced laterally apart equidistant on opposite sides of a longitudinal center plane to form therebetween a wheel receiving track and having a plurality of axle receiving holes spaced longitudinally therealong; a plurality of wheels spaced longitudinally apart in said track, each including a pair of hubs oppositely oriented and configured with a single bearing gland offset to a lateral side of said central plane, the bearing glands of alternate ones of said wheels being offset equidistant to the opposite sides of said longitudinal center plane; axle bolts for receipt in said axle receiving holes for mounting the respective said wheels therefrom; and a single bearing assembly in each respective gland for supporting said rails from the each respective wheel so that, when loaded, the alternate ones of said bearings is loaded at alternate opposite sides of said longitudinal center plane.
