Abstract:
1. A portable car ramp, comprising the combination of first and second separate structural components each having thereon respective generally planar bottom edges suited to be supported on a substantially flat medium surface, and cooperating pin and groove formations angled generally normal to the bottom edges of the respective components operable with limited clearances therebetween to telescope and to interlock the components together against movement in the direction of the elevated wheel run, while allowing relative component shifting in the direction normal to the bottom edges, a unitary friction pad having a second portion extended several inches away from and aligned with the inclined wheel run and suited also to lie against the medium surface, whereby wheel weight on the second portion of the friction pad and on inclined wheel run component compresses said friction pad against the medium surface to resist ramp sliding along the medium surface, while wheel weight on the elevated wheel run component provides no compression of the friction pad which then is ineffective in resisting ramp sliding along the medium surface.
