Abstract

Abstract There is disclosed a protective plate for a skateboard comprising a rigid base member having a mounting bracket thereon with a plurality of holes therethrough adapted to receive bolts from a skateboard wheel assembly for securing the mounting bracket between the wheel assembly and a skateboard body. The rigid base member has a cantilever frame which projects from the mounting bracket and is adapted to extend along and mechanically support and protect the end of the skateboard body adjacent the wheel assembly.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 129 words
A protective plate for a skateboard comprising, a rigid base member having a mounting bracket thereon with a plurality of holes therethrough adapted to receive bolts from a skateboard wheel assembly for securing said mounting bracket between the wheel assembly and a skateboard body, said rigid base member having a cantilever frame which projects from said mounting bracket and is adapted to extend along and mechanically support and protect the end of the skateboard body adjacent the wheel assembly, said cantilever frame having at least one rib projecting from the surface thereof for adding mechanical strength to said cantilever frame and for providing a spliting contact with a surface over which the skateboard is moved when the skateboard is tilted to cause the end thereof to contact the surface.
Claim 2
Dependent Claim 129 words
A protective plate for a skateboard comprising, a rigid base member having a mounting bracket thereon with a plurality of holes therethrough adapted to receive bolts from a skateboard wheel assembly for securing said mounting bracket between the wheel assembly and a skateboard body, said rigid base member having a cantilever frame which projects from said mounting bracket and is adapted to extend along and mechanically support and protect the end of the skateboard body adjacent the wheel assembly, said cantilever frame having at least one rib projecting from the surface thereof for adding mechanical strength to said cantilever frame and for providing a spliting contact with a surface over which the skateboard is moved when the skateboard is tilted to cause the end thereof to contact the surface.
Claim 3
Dependent Claim 52 words
The protective plate for a skateboard described in claim 1 wherein said at least one rib has a surface made of a metal of the type such as rhodium for providing sparks when said at least one rib moves in sliding contact with a paved surface over which the skateboard is operated.
Claim 4
Dependent Claim 126 words
A protective plate for a skateboard comprising; a rigid base member having a mounting bracket thereon with a plurality of holes therethrough adapted to receive bolts from a skateboard wheel assembly for securing said mounting bracket between the wheel assembly and a skateboard body, said rigid base member having a cantilever frame which projects from said mounting bracket and is adapted to extend along and mechanically support and protect the end of the skateboard body adjacent the wheel assembly, said rigid base member being a substantially rectangular plate, one end thereof being the mounting bracket and the remaining portion thereof being the cantilever frame, said rectangular plate having an elongated rib centrally located on said remaining portion of said substantially rectangular plate forming said cantilever frame.
Claim 5
Dependent Claim 126 words
A protective plate for a skateboard comprising; a rigid base member having a mounting bracket thereon with a plurality of holes therethrough adapted to receive bolts from a skateboard wheel assembly for securing said mounting bracket between the wheel assembly and a skateboard body, said rigid base member having a cantilever frame which projects from said mounting bracket and is adapted to extend along and mechanically support and protect the end of the skateboard body adjacent the wheel assembly, said rigid base member being a substantially rectangular plate, one end thereof being the mounting bracket and the remaining portion thereof being the cantilever frame, said rectangular plate having an elongated rib centrally located on said remaining portion of said substantially rectangular plate forming said cantilever frame.
Claim 6
Dependent Claim 31 words
The protective plate for a skateboard described in claim 3 further including two additional elongated ribs, each additional rib extending the length of said substantially rectangular plate adjacent one edge thereof.
Claim 7
Dependent Claim 102 words
A protective plate for the arched end of a skateboard, comprising a metal plate adapted to be secured to the underside of an arched end of a skateboard, said metal plate being arched to mate with and match the curved surface of the skateboard arched end, one end of said metal plate being adapted to be mechanically secured between the body and a wheel assembly of the skateboard adjacent the arched end thereof, said metal plate having a plurality of parallel elongated ribs for mechanical strength and for providing a ribbed skidding and braking surface at the arched end of the skateboard.
Claim 8
Dependent Claim 102 words
A protective plate for the arched end of a skateboard, comprising a metal plate adapted to be secured to the underside of an arched end of a skateboard, said metal plate being arched to mate with and match the curved surface of the skateboard arched end, one end of said metal plate being adapted to be mechanically secured between the body and a wheel assembly of the skateboard adjacent the arched end thereof, said metal plate having a plurality of parallel elongated ribs for mechanical strength and for providing a ribbed skidding and braking surface at the arched end of the skateboard.
