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-liner roller skate usable by a skater on a riding surface comprising: a plurality of wheels centered on a common plane, each said wheel having a central axis of wheel rotation with all said axes being perpendicular to said common plane; a plurality of wheel axles with a said axle positioned on said central axis of each said wheel; each said wheel including bearing means for rotatably mounting said wheels for rotation about said axles; a boot having a heel and sole; a frame carrying said wheel axles and having a top and a bottom, said frame being formed of a lightweight, plastic-like material and including: a pair of substantially parallel side rails extending longitudinally forwardly and rearwardly and having a plurality of pairs of axle apertures passing therethrough to mount said axles therein; a sole bracket attached to said sole of said boot and having leading and trailing edges; a heel bracket attached to said heel of said boot and having a leading edge; and a plurality of rigid, bifurcated webs spaced longitudinally apart from each other along said side rails, each said web having a forwardly extending bifurcation and a rearwardly extending bifurcation, each said bifurcation connected with and extending between said side rails, with said bifurcations of each web meeting at a convergence, said bifurcations cooperating with each other to reinforce said side rails, to prevent significant deformation of said frame, to maintain said side rails parallel to each other and to keep said wheel axles mutually parallel during coasting so as to avoid undesired friction with said bearing means caused by nonparallel axle alignment when said frame is exposed to deformation and vibration forces generated by road bumps and roughness.
