Abstract
A vehicle ramp supports a wheel in an elevated position spaced above the ground. The vehicle ramp includes an elongated body and an upright column. The upright column is substantially surrounded by the body. The column presents respective parts of the upper surface of the vehicle ramp and extends downwardly therefrom. The column is defined along the upper surface by a groove that intersects the upper surface and extends endlessly about the column so that the column is isolated from the body along the upper surface.
Claims31
A vehicle ramp to engage and support a wheel in an elevated position spaced above the ground, said vehicle ramp comprising:
- an elongated body forming at least part of a platform section to support the wheel in the elevated position and at least part of an inclined ramp section to permit the wheel to be rolled between the elevated position and a position on a ground surface,
- said platform and inclined ramp sections cooperatively presenting a ground-engaging lower surface and a wheel-supporting upper surface;
- and
- an upright column substantially surrounded by the platform section,
- said column presenting respective parts of the upper surface and extending downwardly from the upper surface to the ground-engaging lower surface, with the column not extending above the upper surface along the platform section,
- said column being defined along the upper surface by an endless surrounding groove that intersects the upper surface and extends endlessly about the column so that the column is isolated from the body along the upper surface.
A vehicle ramp to engage and support a wheel in an elevated position spaced above the ground, said vehicle ramp comprising:
- an elongated body forming at least part of a platform section to support the wheel in the elevated position and at least part of an inclined ramp section to permit the wheel to be rolled between the elevated position and a position on a ground surface,
- said platform and inclined ramp sections cooperatively presenting a ground-engaging lower surface and a wheel-supporting upper surface;
- an upright column substantially surrounded by the body,
- said column presenting respective parts of the upper surface and extending downwardly therefrom,
- said column being defined along the upper surface by a surrounding groove that intersects the upper surface and extends about the column so that the column is isolated from the body along the upper surface,
- said column being part of the platform section;
- and
- an upright second column substantially surrounded by the body and being part of the inclined ramp section,
- said second column being defined along the upper surface by a second surrounding groove that intersects the upper surface and extends endlessly about the second column so that the second column is isolated from the body along the upper surface,
- said body presenting an intermediate groove that intersects the upper surface and the first and second surrounding grooves and extends longitudinally therebetween.
A pair of nestable vehicle ramps to support a wheel in an elevated position spaced above a ground surface, each of said nestable vehicle ramps comprising:
- a body forming at least part of a platform section to support the wheel in the elevated position, with the body being operable to permit the wheel to be rolled between the elevated position and a position on the ground surface,
- said body including upright side walls and an upper wall that interconnects and extends between the side walls,
- said upper wall presenting a wheel-supporting upper surface that defines an upper surface area,
- said body defining an inner chamber between said walls and an open face communicating with the inner chamber,
- said open face defining a face area that is greater than the upper surface area so that the upper surface of one of the vehicle ramps can be received through the open face and at least partly within the inner chamber of the other of the vehicle ramps;
- and
- an upright column substantially surrounded by the platform section,
- said column presenting part of the upper surface and projecting downwardly from the upper surface to the ground-engaging lower surface, with the column not extending above the upper surface along the platform section,
- said column defining a hollow center spaced below the upper surface, with the column of one ramp received in the hollow center of the other ramp when the one ramp is received through the open face of the other ramp,
- said column being defined along the upper surface by an endless surrounding groove that intersects the upper surface and extends endlessly about the column so that the column is isolated from the body along the upper surface.
A pair of nestable vehicle ramps to support a wheel in an elevated position spaced above a ground surface, each of said nestable vehicle ramps comprising:
- a body operable to support the wheel in the elevated position and to permit the wheel to be rolled between the elevated position and a position on the ground surface,
- said body including upright side walls and an upper wall that interconnects and extends between the side walls,
- said upper wall presenting a wheel-supporting upper surface that defines an upper surface area,
- said body defining an inner chamber between said walls and an open face communicating with the inner chamber,
- said open face defining a face area that is greater than the upper surface area so that the upper surface of one of the vehicle ramps can be received through the open face and at least partly within the inner chamber of the other of the vehicle ramps;
- an upright column substantially surrounded by the body,
- said column presenting part of the upper surface and projecting downwardly from the upper surface to define a hollow center spaced below the upper surface, with the column of one ramp received in the hollow center of the other ramp when the one ramp is received through the open face of the other ramp,
- said column being defined along the upper surface by a groove that intersects the upper surface and extends about the column so that the column is isolated from the body along the upper surface,
- said elongated body forming at least part of a platform section to support the wheel in the elevated position and at least part of an inclined ramp section to permit the wheel to be rolled between the elevated position and a position on the ground,
- said column being part of the platform section;
- and
- an upright second column substantially surrounded by the body and being part of the inclined ramp section,
- said second column being defined along the upper surface by a second surrounding groove that intersects the upper surface and extends endlessly about the second column so that the second column is isolated from the body along the upper surface,
- said body presenting an intermediate groove that intersects the upper surface and the first and second surrounding grooves and extends longitudinally therebetween.
