ABSTRACT:
A foldable ramp includes first and second sections longitudinally aligned with each other and joined by a hinge assembly permitting the sections to be pivoted to a working position in which the sections form a continuous, substantially straight ramp with adjoining ends abutting against each other and a storage position in which one of the first and second ramp sections is folded against the other. The hinge assembly includes four links extending along the first and second ramp sections and first and second pins transversely extending through the first and second ramp sections, respectively, and through each of the links.
