Abstract
A ramp may include a frame having first and second end portions and at least one rung extending substantially between the frame and being positioned between the first and second end portions, the at least one rung forming at least a portion of a ramp surface. The ramp may further include a plate extending substantially between the frame and being positioned adjacent to at least one of the first and second end portions, and a lip pivotally attached to the plate at a pivot axis, wherein the pivot axis is non-load bearing.
Claims33
A ramp comprising:
- a frame having first and second end portions;
- at least one rung extending substantially between the frame and being positioned between the first and second end portions, the at least one rung forming at least a portion of a ramp surface;
- a plate extending at least partially between side rails of the frame and being positioned adjacent to at least one of the first and second end portions;
- and
- a lip pivotally attached to the plate at a pivot axis, wherein the pivot axis is non-load bearing.
A ramp comprising:
- a frame having first and second end portions;
- at least one rung extending between at least a portion of the frame, the rung forming at least a portion of a ramp surface;
- a plate extending at least partially between side rails of the frame at either of the first and second end portions of the frame;
- and
- a lip pivotally attached to the plate and biased downward relative to the ramp surface.
A ramp comprising:
- a frame having a length;
- a ramp surface extending between the frame along at least a portion of the length;
- a plate extending at least partially between side rails of the frame;
- a lip pivotally attached to the plate at a pivot axis;
- and
- a biasing member biasing the lip downward relative to the ramp surface, wherein the lip is capable of engaging at least one of a ground surface and a vehicle.
The ramp of clam 26 further comprising a pivot shaft pivotally attaching the lip to the plate forming at least a portion of the pivot axis.
A ramp comprising:
- a frame having first and second end portions;
- at least one rung extending between at least a portion of the frame, the rung forming at least a portion of a ramp surface;
- a protective plate extending at least partially between side rails of the frame at either of the first and second end portions of the frame;
- and
- a lip pivotally attached to the plate at a pivot axis and biasing downward relative to the ramp surface, wherein the protective plate is load bearing and the pivot axis is not load bearing.
A ramp comprising:
- a frame having first and second end portions;
- at least one rung extending between at least a portion of the frame, the rung forming at least a portion of a ramp surface;
- and
- a transition plate extending at least partially between side rails of the frame at either of the first and second end portions of the frame, wherein at least a portion of the transition plate is biased downward relative to the ramp surface.
