The Fig. 1 schematically shows an escape route security device 1 with a door with a door frame TF rotatably mounted in a door frame TR by means of two hinges TB. The door may be an escape and escape door, also known as a panic door. The door hinges TB are spaced apart along a vertical axis of rotation of the door. The door hinges TB are at an in Fig. 1 provided on the left vertical side of the door. The door leaf TF is preferably a stop pivot wing. Designs of the door with a pendulum wing are possible with appropriate design of the door hinges.

On the door leaf TF a push rod device or panic push rod 101 is mounted with a handle 10. In the housing of the panic push rod an emergency button 30 is integrated with a sliding display 301.

The handle 10 cooperates with a locking device. The locking device comprises a mechanical locking element and an optional electrical locking element. An inserted in the door leaf, designed as a mortise door lock 20 acts as a mechanical locking element. An overhead on the door frame TR arranged escape route lock 40 in the form of an electromagnet, with an adhesive plate arranged on the door leaf cooperates, is formed as an optional electrical locking element. The electrical locking element 40 is preferably operated in the quiescent current mode. This means that when energized, the door is locked and in the de-energized state, the door is open. In an alternative embodiment, the electrical locking element 40 may also be omitted.

In order to enable safe unlocking of the door in an emergency, the locking device is designed switchable. Upon actuation of the handle 10, the locking device is unlocked. At the same time, an audible and / or visual alarm is generated. Even when pressing the emergency button 30, the locking device is unlocked and generates an audible and / or visual alarm.

The Fig. 2 shows an escape route security device with an alternative embodiment of the panic push rod 101. The panic push rod 101 has a handle 10 for releasing the locking device. In the actuating handle 10, a display 301 is arranged to display status information and / or image information to a user. In an advantageous embodiment, the display integrated into the handle can also be designed as an emergency button 30, in that the display 301 is designed to be displaceable. For this purpose, a mounting frame can be arranged in the handle 10, in which the display 301 is slidably mounted and cooperates with an electrical switching contact. The locking device of the escape door, consisting of the door lock 20 and an electrical locking element 40, can then be unlocked via the electrical switching contact.

In the Fig. 3 a schematic representation of the panic push rod 101 in the region of the emergency button 30 is shown. The panic pressure rod 101 has a housing 102, in which the handle 10 is slidably mounted via a linear guide. Further, a mounting frame 103 is provided in the housing 102, which receives the emergency button 30. The mounting frame 103 is disposed at a front end of the housing 102. It can be arranged either at the left or at the right end of the housing 102. The recorded in the mounting frame 103 emergency button 30 is designed as a plug-in module.

The emergency button 30 comprises a displaceably mounted display 301, which is covered by a cover 107 to the front. The cover frame 107 protects the display 301 against disturbing mechanical influences. The display 301 is designed as a touchscreen and serves as a control and / or display device. Text information and image information can be shown on the display. Likewise, inputs can be made via the display 301 by display panels or control buttons on the display, which trigger a corresponding function after touching the same. Connected to the display 301 is a control device 302 which is located in the Fig. 4 is shown in more detail. The control device 302 is arranged together with the display on a chassis 105. The chassis 105 is slidably mounted in the mounting frame 103. In the Fig. 4 the shifted down position of the display 301 is shown. The display 301 is thereby pressed together with the control device 302 and the chassis 105 in the housing of the panic push rod 101. This is done against the force of return springs 304, the movable display 301 in the in the Fig. 3 act on the neutral position shown. The springs 304 are designed as coil springs and act between an abutment 104 fixedly connected to the housing 102 and the movably mounted chassis 105. The mounting frame 103 has a stop 106 in the form of an L-shaped extending end edge. This prevents the sliding display 301 from being pushed forward out of the housing 102 by the springs 304. As in Fig. 3 can be seen, the display 301 is in its neutral position directly to the stop 106. In the Fig. 4 on the other hand it can be seen that the actuated, ie pushed into the housing 102, display has a distance from the stop 106.

In the Fig. 5 a section through the housing 102 of the panic push rod 101 in the area of the emergency stop switch 30 is shown. It shows the Fig. 5 the non-actuated position of the display 301. In the Fig. 6 the actuated position of the display 301 is shown. Otherwise, the figures agree. As in the Figures 5 and 6 illustrated, the emergency button 30 is formed as a plug-in module comprising the display 301 and the cover 107, which are mounted together on a chassis 105. The control device 302 is thus arranged directly behind the display 301 and fastened between the chassis 105 and the display 301. Via a cable connection, the control device 302 is connected to the display 301. Left and right of Nottastenmoduls the mounting frame 103 is provided, which leads the emergency button 30 slidably. An abutment 104 is fixedly connected to the housing 102 and forms a stop for the return springs 304. The return springs 304 act on the display 301 in the direction of Fig. 5 illustrated neutral position.

The Fig. 6 indicates the actuated position of the display 301. Between the springs 304, an electrical switching contact 303 is arranged, of a pressure plate in the in Fig. 6 shown position is actuated.

By pressing the emergency button, so moving the display 301, the electrical switching contact of the in Fig. 5 shown starting position down until it comes into contact with the electrical switching contact 303 opposite pressure plate. As a result, the electrical switching contact is actuated. The electrical switching contact 303 may be designed as normally open or normally closed switching contact. In order to enable a reliable unlocking in terms of high reliability, it is provided to form the switch contact 303 as a normally closed contact, which is opened upon actuation of the display 301, ie when the display 301 is pushed into the housing. Thus, the electrical switching contact 303 is designed as a positive opening contact.

In an alternative embodiment, the electrical switching contact 303 may also be designed as proximity or touch switch, in particular as Hall or read switch, which controls the control device 302. In that case, a release device for releasing the locking device is provided on the control device 302, so that the control device 302 activates the locking device for releasing the door. This can be done via a direct cable connection. However, it is also provided that in one embodiment, the control device 302 has a digital interface and the release of the locking device is digitally controlled via a bus system. The bus system can be designed as a serial bus, in particular as a CAN bus.

The slidably mounted display 301 is, as in the FIGS. 7 to 9 shown assembled with further assemblies on the chassis 105. The chassis 105 is formed together with the display 301 as a unit and slidably mounted. For repair purposes, the assembly of display 301 and chassis 105 is easily replaceable. The chassis 105 is acted upon by springs 304 in a neutral position in which it rests against the inside of a housing of the emergency button 30 and the cover frame 107. The chassis 105 has stops 117 on which abut in the neutral position on the inside of the housing of the emergency button 30 and the cover 107. By pressing on the front side of the display 301, the chassis 105 and thus also the display 301 against the force of the springs 304 into the housing 102 in pushed. At the end of the displacement path, an electrical switch contact 303 is actuated to release a locking device of the door and / or to generate an alarm. The in the in the FIGS. 7 to 9 shown springs are formed as leaf springs 304. They are arranged on the rear wall of the chassis 105. The springs 304 may alternatively be formed as helical compression springs.

The chassis 105 has a parallel guide which is intended to prevent tilting of the chassis 105 and / or the display. The chassis is guided in parallel to brackets 117b, which are arranged on the rear wall of the chassis 105 and supported on the inner wall of the housing bottom. The chassis 105 is therefore inserted into the housing 102 without jamming. The brackets 117b are formed as double U-shaped brackets which are pivotally supported at their end portions and whose connecting portion slides over the inner wall of the housing bottom when the chassis 105 is displaced.

The display 301 is formed by inlet bevels 112s formed on the cover frame 107 (see FIG Fig. 7 ) are centered in the cover frame, wherein the front edges of the chassis 105 cooperate with the inlet slopes 112s. The inlet slopes 112s support the display 301 in the neutral position accurately and in particular clearance. When the display 301 is moved into the housing, the inlet bevels 112s widen so that jamming of the display 301 is prevented.

On the chassis 105, the controller 302 is arranged. This includes u. a. a graphics board 117g for driving the display 301 and a control board 117s. On the control board 117s electrical interfaces with connectors 117p are arranged, which are provided for example as ports for signal transmission between the control board 171 s and the graphics board 117g and between the control board 171 s and sensors and / or switches and / or actuators. In addition, the control device 302 has a digital interface for connection to a digital bus. Via the bus, the control device 302 can be connected to further escape route security devices and / or to central control or access control systems. The display 301 is designed as a touch-sensitive display or touchscreen on which, for example, a stylized emergency key and / or a keypad for entering an access authorization code can be displayed.

In the 10 to 15 is the in Fig. 1 and 2 Door pan side mounted panic push rod 101 shown schematically in a specific embodiment. The handle 10 is formed in the illustrated case as a push rod device. This push rod device has an actuating element as a perpendicular to the door leaf level movable push rod 10.

With the operation of this push rod 10, a pivotable in the door leaf bearing 1l 1h lever is actuated, which engages with its one end to the inside of the push rod 10 and with its other end in a first push rod 1a, in the door leaf fixed bearing 1l of the push rod device linearly displaceable is arranged. Parallel to this first push rod 1a, a second push rod 1 b is also mounted linearly displaceable in the door leaf bearing. This second push rod 1b is connected to the lock nut 20n of the door lock 20 mounted in the door leaf via a crank rocker or the like. Between the first push rod 1 a and the second push rod 1 b, a clutch spring 1 f is arranged. This clutch spring 1f is formed in the illustrated case as a helical compression spring. It is supported with its one end on the second push rod 1 b and has at its other end a spring plate 1 ft, which can be acted upon by the output 1 ma of a first push rod 1a supported electric motor 1m to charge the clutch spring 1f d. H. to compress in the illustrated case.

This position is in Fig. 11 shown. On the first push rod 1a a driver stop 1 aa is arranged, which is in contact with the push rod 1 b. At the second push rod, a driver stop 1 bb is arranged, which is in abutment with the push rod 1 a. On the second push rod 1 b, an electric locking device 1 e is arranged on which the spring 1f in the charged, ie in the illustrated case compressed state, is supported with its spring plate.

This position shows Fig. 13 , In this position, the second push rod 1 b is decoupled from the first push rod 1a, ie upon actuation of the first push rod 1a by the push rod formed as an actuating element 1, the first push rod 1a in Fig. 13 shifted to the right, without the second push rod 1 b, which is connected to the lock nut 20n, taken along. The supported on the first push rod 1a motor 1 m is arranged here with retracted output, so that in Fig. 13 in the initial position existing distance a between the motor output 1 ma and the detected on the blocking device 1e spring plate 1ft is present and thus the first push rod 1a in this path is freely movable without abutment against the spring plate 1ft, the second push rod 1 b supported clutch spring 1f to arrive.

When the blocking device 1 e is turned off, the blocking of the clutch spring 1 f is released, with the result that the clutch spring 1 f relaxes and in the illustrated case in Fig. 13 the spring plate is moved to the left and comes in contact with the output 1 ma of the first push rod 1 a supported electric motor 1 m. This position is in Fig. 11 shown. In this position, the first push rod 1a is coupled to the second push rod 1 b. This means that upon actuation of the first push rod 1a via the push rod 1, in which the push rod 1 is moved to the right, the second push rod 1 b is taken, that is also displaced to the right. The second push rod 1 b coupled to the lock nut 20 n thus unlocks the lock 20.

The panic push rod 101 has, as in the FIGS. 10 to 15 can be seen, nor a coupling element 1 k, which in the normal operation of the device is decoupled and only coupled when an authorized person to press the lock 20.

The emergency button 30 has a code input device for this purpose. The code input device comprises a keypad displayed on the display 301. After pressing a control surface shown on the display 301, the keypad is displayed. An access code can now be entered via the keypad.
