    Abstract: 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.
