发明名称 Loading and bridge ramp for pick-up trucks
摘要 A ramp for loading a pick-up truck that is collapsable so that it can be transported and stored in a minimum space. The ramp is removably mounted to the rear tail gate of a pick up truck. The ramp includes three contiguously hingedly connected rectangular flat members that open or distend with their planes at predetermined angles with respect to each other. This is accomplished by sharing the load placed on said flat members between the shear on the hinge assemblies and the angled abutting edges compression load. The shaft of one of the hinge assemblies extends and a handle member is mounted thereon for prompt manipulation of the ramp.
