Abstract: An in-line roller skate having a frame including a pair of side rails, each side rail having front and rear mounting brackets for attachment of the frame to the boot of the in-line roller skate. Each frame side rail includes a curved portion and a planar portion. The planar portion carries a plurality of axle apertures through which an axle for a wheel may be inserted. Perferably the axle apertures are configured to receive an axle aperture plug, have an eccentrically disposed axle bore and are situated on the frame side rails such that the wheels may be mounted at multiple relative heights to each other.

Abstract: An in-line roller skate and brake utilizes an improved braking assembly in which the brake pad is retained to the brake housing by an interacting tongue and slot system which causes the pad to be tightly forced into the housing during braking. The upper face of the pad is retained to the housing, and compression of the rubber pad forces a slot on the periphery of the pad tightly into locking engagement with the housing so as to provide a substantially improved retention system for the brake pad during heavy braking operation.

Abstract: A roller skate and brake utilizes a generally flat rectangular road surface engaging base which pivots about the rear wheel through an arc of approximately twelve degrees to achieve full facial engagement with the road surface to achieve safer, more controlled braking. The brake pad is provided with an internal plate which provides an audible and vibrating wear indicator to alert the skater to replace the brake pad. The pad has an upright, arcuate protuberance and a transverse rib which are mateably received within an arcuate cross section socket and a slot adjacent the socket to closely restrain and confine the brake pad within a brake pad housing when the brake pad is attached to the housing.

Abstract: An in-line roller skate utilizes dual position, eccentric axle aperture plugs which are received in the axle apertures of the skate frame to allow mounting of the skate's wheels in either of two distinct orientations. The plugs also solve a serious assembly problem by allowing wheels to be installed in the skate frame without the alignment problems previously encountered between frames, wheels and hard to handle spacing washers.

Abstract: 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.
