Abstract: A push/pull door latch assembly for use in a door includes a handle assembly and a latch cylinder. The handle assembly has a stop configured for limiting the movement of the handle during the push or pull operation, and absorbing shock transmitted from a user's hand through the handle and a cam assembly that operates in response to the push or pull operation of the handle. The cam assembly operates the latch so as to unlock the door when the handle is pushed or pulled.

Abstract: A flush bolt includes a bolt head and a strike. The bolt head moves out of the flush bolt in response to movement of the strike into the flush bolt, through a movable cam surface in the flush bolt. The bolt head is withdrawn towards the flush bolt when the strike is released.

Abstract: A flush bolt mechanism for use in connection with a pair of swingable doors to provide latch bolt engagement between the free ends of those doors. The flush bolt mechanism includes a generally flat frame or plate adapted to be mounted on a flat frame or plate adapted to be mounted flush on one of the free ends of the swingable doors, and a support bracket mounted on the back thereof. The support bracket provides a means for mounting an adjustment bracket thereon in reciprocal position thereon. A trigger mechanism is also mounted in reciprocal position on the support bracket so as to extend through the flush mounted plate. The trigger mechanism and the adjustment bracket are mounted on the flat plate and the support bracket to be reciprocally moved toward the plate and away from the plate in continuous adjustment to provide for adjusting the extended position of the trigger means mounted on the adjustment bracket.

Abstract: The present invention is a compact door coordinator which includes a relatively narrow housing having mounted therein and extending therefrom a lead control lever and a longer trailing control lever. Both control levers are spring biased to extend from the housing when the doors are open. A relatively simple linkage extends from the lead control lever to the trailing control lever for retaining the ladder in its extended position until the lead door contacts the lead control lever. At that point, the lead control lever is pushed into the housing and rotated against the force of a torsion spring, causing the linkage to move and thereby rotating a cam which then releases the trailing control lever allowing the trailing door to push the trailing control lever into the housing to complete the closing process.
