ABSTRACT:
A cargo elevator system, that includes a pivotable cargo platform, particularly adapted for mounting on a truck. The system is operable through a unique open/close sequence for translating the platform between a substantially vertical, upright storage position, and a horizontal elevator use position that permits the truck to be loaded and unloaded. The system is characterized by a unique latching mechanism for latching the platform in, and unlatching the platform from, the storage position. The system is also characterized by a first fail-safe structure for preventing the platform from swinging on its pivot axis toward ground level beyond its horizontal elevator use position. The system is further characterized by a second fail-safe structure that prevents the platform from moving out of its vertically upright position when so stored. The system is further characterized by a novel fastener mechanism for holding the platform's ramp in a cart stop position as the platform is raised and lowered during elevator use.
