Title: Dimpled door hardware

Abstract: An over-the-road vehicle in the nature of a trailer or a van has a body provided with an open end formed by oppositely disposed side pillars, a header and a sill. A pair of doors are hinged to the pillars with channel members secured near the opposite door edges having bearings at the ends in which locking rods are secured against edgewise movement while being pivotally mounted within the channel members. The ends of the rods are supported in cantilever from the ends of the channel members having on the ends a cam finger which engages cams within castings secured to the header and sill by which the doors are moved to secured closed position when the rods are rotated. When a load is applied to the inner surface of the door, the ends of the locking rods will bend from the ends of the channel members providing a bending moment from the channel ends to the ends of the rods. When the force is substantially increased, the rods will engage the edge of the door to change the length of the bending moment arm thereby withstanding the increased load without any permanent damage to the hardware or door edge.
