ABSTRACT:
A device and method for locking a slidable and tiltable truck bed against tilting when the truck bed is in the forward position adjacent the truck cab are presented. The device includes a movable actuator that communicates with the truck's hydraulic system to effect tilting. If this actuator is prevented from moving, the tilting function cannot be accessed. The actuator is locked by restraining its top end between two tabs at one end of a hinge. A spring positioned between a fixed support, to which is also affixed the other end of the hinge, and one of the tabs, in the absence of compression, permits the actuator free motion; upon a forward sliding of the truck bed, however, the spring is compressed, moving the tabs downward to engage and restrain the actuator top end.
