A multi-point closure control mechanism or lock especially designed for use with rear and/or side doors of a closed body highway truck, particularly a so-called panel truck, and for use with doors of military vehicles. The closure control mechanism comprises two dead bolts, slidably supported in suitable brackets adjacent to the upper and lower edges of a door near its free vertical edge, that engage keepers or catches in the form of plates on the vehicle body. Each bolt has a free running roller therein to facilitate entrance and retraction of the bolt into and out of engagement with its respective keeper or catch. The dead bolts are connected by rod members to pivots eccentrically located on a lock operating member rotatable in a frame member fixed to the door intermediate the bolts. The operating member also includes a cylindrical rod-like projection extending normal to the free edge of the door when the bolts are engaged with their keepers or catches at the top and bottom of the door. The rod-like projection has a roller to facilitate its engagement with and release from a keeper or catch. One embodiment of the aperture member has a mechanism for selectively disabling an outside handle connected to the mechanism.

In a closure control mechanism attached adjacent to a free edge of a door swingable into and out of an opening with in a wall, a dead bolt lock assembly including a frame immovably mounted on the door and a pair of dead bolts, each having an end, the dead bolts movable within the frame for extension and retraction of the ends of the dead bolts into and out of engagement with a pair of keeper surfaces located on the wall and extending in the direction of extension and retraction; a first surface on one end of each dead bolt transverse to the direction of movement, angularly oriented for substantially the full thickness of the bolt, facing in the direction of extension, facing in the direction of the door swings when the door is swung out of the opening in the wall, facing the keeper surface when the door is in the opening and when the dead bolt lock assembly is in an extended position and facing the door when the dead bolt lock assembly is in a retracted position; a rotatable member in said one end of each dead bolt engageable with the keeper surface to facilitate both extension and retraction of the bolt relative to the keeper; a second surface at said one end of each dead bolt extending in the direction of bolt movement, facing the keeper surface when the dead bolt lock assembly is in an extended position and facing the door when the dead bolt lock assembly is in a retracted position, said rotatable member extending beyond said second surface in rolling engagement with the door or the keeper surface during extension or retraction of the dead bolts; a manual bolt-operating member rotatably supported in the frame; and a pair of rod members operatively connected to the dead bolts and to the bolt-operating member eccentrically of the axis of rotation thereof to extend and retract the dead bolts concurrently.
