ABSTRACT:
This portable car ramp has two structural components coupled longitudinally together, while allowing limited relative vertical movement when each's bottom edge rest on a medium surface. The first component has an elevated wheel run while the second component has an inclined wheel run. When coupled together, the component wheel runs are longitudinally aligned, meeting at a corner, so that a vehicle wheel can roll up the inclined run, over the corner, and onto the elevated run, and vice-versa. Friction pads fixed to the second component bottom edge increase resistance against ramp sliding along the medium surface, particularly with the wheel supported on the inclined wheel run. The first component has no bottom edge friction pads so that car ramp sliding along the medium surface is possible, such as should the wheel be rolled against a stop on the elevated wheel run.
