An in-line roller skate includes a new lightweight frame and brake of synthetic material and embodies structurally interacting components which cooperate to counter and absorb the strain and shock of road bumps and vibration encountered at high speeds by heavy riders and which have in the past required heavy, metal frames. An improved wheel hub solves the problem of overheating bearings and wheel melting encountered by earlier skates and permits prolonged, high speed use of the skates on nonlevel riding surfaces by even heavy skaters under hot road surface conditions.

An in-line roller skate unable by a skater on a riding surface and capable of reducing heat damage to the in-line skate during operation comprising: a plurality of wheels, each said wheel having a central axis of wheel rotation and each wheel including a tire member formed of resilient, yieldable, synthetic material and having an outer tire rim whose radial cross section is substantially semicircular; a plurality of wheel axles equal in number to said plurality of wheels with one of said axles positioned on said central axis of each said wheel; a frame for carrying said axles so as to rotatably mount said plurality of wheels on said frame and substantially center all said wheels on a common plane with the central axes of rotation of said wheels being substantially perpendicular to said common plane; attachment means connected to said frame capable of releasably securing said frame to the skater; each of said wheels further including a hub and bearing means carried by said hub, each said hub being an integral body and including first and second concentric, substantially rigid rings with each said ring having a side to side width and said width of each said ring being centered on said common plane, said tire member being molded about said hub integral body; and each said hub further including a plurality of substantially rigid vanes transverse to said common plane and extending between and interconnecting said first and second rings to maintain said rings in substantially concentric relationship during operation of the skate so as to reduce destructive overheating and resultant melting of said tire member by preventing unwanted canting of said first ring relative to said second ring when said common plane of said wheels is nonvertical to the riding surface.
