ABSTRACT:
An automotive service ramp comprising a unitary body member including a ramp portion with integral side stiffening, tire retaining rails, a contoured rest portion to receive the tire of an automobile, and an extension beyond the rest portion which constitutes a leg portion.
The ramp portion has transverse corrugations, is contoured transversely to match normal tire cross sections and has depending stiffening sides. A slight edge rail extends above the surface of the ramp.
A handle is pivotally secured to the body in a position whereby it may be grasped to carry the ramp with the ramp portion hanging downward. The handle is pivoted to overlie the rest and leg portion when not in use and to be out of the way. An integral retainer portion of the body member holds the handle at a fixed position when not in use. The handle is so contoured that if it is left in an unsecured position and an automobile wheel ascends the ramp, the tire snaps the handle into its stored position without damage either to the handle or to the tire. The handle and the retainer portions cooperate whereby movement of the handle into its stored position produces an identifiable sound to inform the user that the handle is in place.
