Abstract

Abstract A thermoplastic roller skate of adjustable length has a toe supporting section, a heel supporting section, and an extensible shank portion. The toe section consists of a toe platform and a rearwardly extending rectangular bar shaped first shank member integrally joined to the toe platform. The heel section consists of a heel platform and a second shank member having a rectangular bar shaped channel, wherein the second shank member is integrally joined to a forward portion of the heel platform. The first shank member is slidably contained in the channel of the second shank member. A mechanism is provided for locking in position the first shank member within the channel of the second shank member. An axle assembly is affixed to the underside of the heel and toe platform. A five inch plastic wheel is affixed to each end of the two axle rods.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 377 words
A roller skate, which comprises: a. a toe supporting section having a rectangularly shaped forward toe platform joined integrally to a forward first shank member of a rectangular bar shaped configuration, a bottom base of said first shank member having a threaded aperture therein; b. a first axle assembly communicating with an underside of said forward toe platform; c. a heel supporting section formed from a planar rear heel platform having a curved rear edge and a second shank member extending forwardly from said heel supporting section, said second shank member including an elongated rectangularly shaped plate, a pair of L-shaped flange members extending downwardly from each side of said plate, wherein the horizontal portions of said L-shaped flange members extend inwardly towards each other forming a gap between said horizontal portions, said plate and said L-shaped flange members defining a rectangularly shaped channel therein, and said first shank member being slidably contained within said rectangularly shaped channel; d. a horizontally placed clamp plate having a central opening therethrough, said clamp plate engaging a bottom surface of said horizontal portions of said second shank member; e. a wing screw extending upwardly through said central opening of said clamp plate to threadably engage said threaded aperture in said first shank member said first shank member and said clamp member frictionally engaging said horizontal portions of said second shank member as said wing screw threadably engages into said threaded aperture of said first shank member; f. a heel guard portion extending upwardly from said curved rear edge of said heel supporting section; g. a second axle assembly communicating with an underside of said planar rear heel platform; h. a pair of large plastic wheels communicating with each said first and second axle assemblies, said axles extending through said wheels; i. a pair of first strap bracket members joined to said toe platform; j. a pair of second strap bracket members joined to said heel platform, said second strap members extending downwardly from a rear portion of straight side edges of said heel platform; k. strap members extending through said first and second strap bracket members; and l. a clamp member affixed onto an end of each said axle, each said clamp member being positioned outside of each said wheel.
Claim 2
Dependent Claim 377 words
A roller skate, which comprises: a. a toe supporting section having a rectangularly shaped forward toe platform joined integrally to a forward first shank member of a rectangular bar shaped configuration, a bottom base of said first shank member having a threaded aperture therein; b. a first axle assembly communicating with an underside of said forward toe platform; c. a heel supporting section formed from a planar rear heel platform having a curved rear edge and a second shank member extending forwardly from said heel supporting section, said second shank member including an elongated rectangularly shaped plate, a pair of L-shaped flange members extending downwardly from each side of said plate, wherein the horizontal portions of said L-shaped flange members extend inwardly towards each other forming a gap between said horizontal portions, said plate and said L-shaped flange members defining a rectangularly shaped channel therein, and said first shank member being slidably contained within said rectangularly shaped channel; d. a horizontally placed clamp plate having a central opening therethrough, said clamp plate engaging a bottom surface of said horizontal portions of said second shank member; e. a wing screw extending upwardly through said central opening of said clamp plate to threadably engage said threaded aperture in said first shank member said first shank member and said clamp member frictionally engaging said horizontal portions of said second shank member as said wing screw threadably engages into said threaded aperture of said first shank member; f. a heel guard portion extending upwardly from said curved rear edge of said heel supporting section; g. a second axle assembly communicating with an underside of said planar rear heel platform; h. a pair of large plastic wheels communicating with each said first and second axle assemblies, said axles extending through said wheels; i. a pair of first strap bracket members joined to said toe platform; j. a pair of second strap bracket members joined to said heel platform, said second strap members extending downwardly from a rear portion of straight side edges of said heel platform; k. strap members extending through said first and second strap bracket members; and l. a clamp member affixed onto an end of each said axle, each said clamp member being positioned outside of each said wheel.
Claim 3
Dependent Claim 98 words
A roller skate as recited in claim 1, wherein said first axle assembly further comprises: a. a pair of first downwardly extending bracket elements joined to the sides of said toe platform, wherein each said first bracket element has a first hole therethrough; b. a first ball bearing mounting assembly secured to said underside of said toe platform; c. a first axle rod rotatably contained in said first ball bearing mounting assembly; and d. each end of said first axle rod extending through said first holes, wherein said wheels communicate with said ends of said first axle rod.
Claim 4
Dependent Claim 98 words
A roller skate as recited in claim 2, wherein said second axle assembly further comprises: a. a pair of second downwardly extending bracket elements joined to the sides of said heel platform, wherein each said second bracket elements has a second hole therethrough; b. a second ball bearing mounting assembly secured to said underside of said heel platform; c. a second axle rod rotatably contained in said second ball bearing mounting assembly; and d. each end of said second axle rod extending through said second holes, wherein said wheels communicate with said ends of said first axle rod.
