ABSTRACT:
A hinge and ramp assembly including first and second plate-like members, each having bottom portions and flanged end portions at one end, with a pivotal device disposed therebetween. The plate-like members may be pivoted from a first closed position in which the bottom portions are in face-to-face engagement to a second load bearing position in which the flanged end portions are in face-to-face engagement and are configured to carry loads placed on the assembly which would act to open the assembly further. Ramp members, configured to matingly engage with the inside surface of each plate-like member formed by said bottom and flanged end portion, are attached to the hinge assembly to provide a ramp apparatus which is rigid and may be used to bridge a distance.
