Patent ID: 7003836

Claim:
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 said first component having an elevated wheel run extended generally parallel to but elevated above said bottom edge thereof, and said second component having an inclined wheel run generally elevated above said bottom edge thereof but extended between opposite lower and higher ends respectively that are even generally with its bottom edge and with the first component elevated wheel run; 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, whereby with the elevated end of the inclined wheel run component disposed adjacent the elevated wheel run component, a vehicle wheel can roll up or down the inclined wheel run and onto or off the elevated wheel run, and wheel weight is carried only on the structural component that the wheel is on; and a unitary friction pad having a first portion secured to the inclined wheel run component proximate the bottom edge thereof intended to lie against the medium surface, and 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.
