An entrance for buildings comprises first and second doors mounted in a common door frame, each door including a lock stile positioned adjacent a lock stile of the other door when the doors are closed. A panic device is mounted on at least one of the doors for emergency opening thereof and a retractable latch is extended between the stiles of the doors when closed for minimizing or eliminating the unauthorized forced separation of the stiles into a position wherein the panic device can be actuated with an implement inserted from outside the entrance to release and open the door. Mechanism is included for interconnecting the latch and the panic device for retraction of the latch when the panic device is actuated for opening the door, thus providing both a safe and a secure entrance system.

Building entrance

A safety flush bolt entrance door system includes a pair of doors mounted in an entrance frame for outward opening with each door pivotally supported for individual opening and closing movement. A normally active door is provided with a locking mechanism adapted to engage an opposite, normally inactive, door for securing the doors together. One or more flush bolt mechanism(s) is mounted on the normally inactive door for locking the door with the door frame whenever the locking mechanism on the active door is engaged with the inactive door. A control mechanism is mounted on the inactive door and interconnected with the flush bolt mechanism(s) so that whenever the active door is unlocked, the flush bolt mechanism(s) is releasable in response to an opening force applied against the inactive door.
