Embodiment Construction

[0069] figure 1 A door 1 is shown schematically, which has a door panel 4 rotatably supported on a door frame 2 by means of two door hinges 3 . Door 1 is the escape and rescue access door, also known as the emergency exit door. The door hinges 3 are arranged at a distance from one another along the door pivot axis. The door hinge 3 is located at figure 1 The door 1 is shown on the vertical side in the middle left. The door panel 4 is preferably a side hinged door panel. However, in a corresponding development of the door hinge 3 a door construction as a swing door can be realized, wherein the door panel 4 is designed as a swing door panel.

[0070] A door lock 6 is arranged inside the door panel 4 . door lock device 7 in Figures 1 to 10 The case shown in includes a door lock 6 designed as a plug-in lock, an operating handle designed as a pressure rod 11 and a transfer device that converts the operating stroke of the operating handle into a joint (Nuss) of the door lock ...

Abstract

Described in a door lock device (7) for a panic exit door (1) comprising a door leaf (4). Said door lock device comprises a push bar (11), a door lock (6), and a transmission mechanism which converts a movement of the push bar (11) in the direction of the door leaf (4) into a movement for actuating the door lock (6). As an essential feature, the push bar (11) is arranged on a linear guide, the guide axis of which extends perpendicular to the door leaf (4).

Description

technical field [0001] The invention relates to a door locking device with a pressure bar for doors, windows or similar structures, especially doors in escape or rescue routes, such as emergency exit doors. The invention also relates to a door arrangement, preferably in an escape and rescue route of a building, having a door frame, a door leaf mounted so as to be movable on the door frame, and such a door locking device. Background technique [0002] Escape and rescue doors (emergency exit doors) should be able to open reliably so that people can safely leave the building in a dangerous situation. A pressure lever extending in particular across the width of the door panel and causing the actuation of the door lock ensures that the lock can be opened very simply in an emergency. The known strut has the disadvantage that it also performs a lateral movement while moving perpendicular to the door panel. This may cause trouble when operating the plunger.
