Abstract: A door coordinator for pairs of swinging doors comprising a pair of arms on a common hub pivotally mounted in a bracket on the door frame, a longer arm adapted to move vertically into and out of the path of an active door and a shorter arm provided with a cam surface supplemented or constituted by a roller so located that the inactive door engages the cam surface and/or the roller for controlling the vertical movement of the shorter arm relative to the inactive door and the simultaneous vertical movement of the longer arm into and out of the path of the active door.

Abstract: A door closing coordinator for a pair of oppositely hinged doors where closure of the inactive door withdraws a stopping member from a holding lever for the active door and permits the active door to close after the inactive door. An override mechanism is provided to permit the active door to close first if a predetermined force is applied thereto to avoid damage co the active door.

Abstract: A flush bolt mechanism adapted to be mounted at the vertical edge of the inactive door of a pair of hinged doors. Means are provided to prevent damage to the mechanism due to misalignment of the bolt and the strike plate. All translational motion of the mechanism substantially takes place along a single axis except for the motion of activation.

Abstract: A surface bolt comprising an elongated bolt slideably mounted on an elongated guide member with biasing means acting on the bolt to urge it away from said guide member to normally maintain the bolt in a spaced relation from the guide member. The guide member is mounted on one of a fixed surface and a relatively movable surface and a keeper is mounted on the other. The means for mounting the guide member comprises passages extending through the guide member and the bolt encloses the guide member and covers the passages. A detent is defined between the guide member and the bolt to latch the bolt against retraction when the bolt is in an extended postition so that the bolt must be moved against the biasing means to unlatch the detent before retraction.

Abstract: A self-latching flush bolt for use in the inactive door of a pair of swinging doors, the bolt being on a slide rod which is spring actuated to throw the bolt into engagement with the strike when the trigger is contacted by the active door. A dead-locking lever holds the bolt locked as long as the trigger is depressed; when the active door is opened the bolt may be manually retracted and will be held in retracted position until the trigger is activated. A roller on the bottom bolt rolls on the floor in case the bolt is thrown with the door in an open position.

Abstract: An automatic surface bolt for doors swinging in pairs having a stop to hold the active door open until the inactive door is closed and a top bolt which is actuated by movement of the stop to lock the inactive door as the active door completes its closing movement, the inactive door having also a bottom bolt arranged to be actuated by the top bolt so that the door is bolted top and bottom when both doors are closed; both bolts holding the inactive door are automatically released when the active door is opened.
