The invention is based on the object of specifying a counter case for a panic door lock with a small backset, which is suitable for both passive leaves and active leaves of double-leaf panic doors and for both DIN directions.

This object is achieved by the features of the counter box for a panic door lock according to patent claim 1.

Advantageous configurations and developments of the invention are specified in the remaining claims.

In order to specify a counter case for a panic door lock with a small backset, which is suitable for both passive leaves and active leaves of double-leaf panic doors and for both DIN directions, a first transmission device is designed as a rack drive and comprises a first rack formed on a first push element , which has a gear with one on a second thrust element formed second rack is coupled. In addition, the counter-box for a panic door lock comprises a housing, a pressure follower rotatably mounted therein, at least one actuating means which can be acted upon by the pressure follower and which actuates the first pushing element in a first actuation direction when the pressure follower is actuated against a spring action. The first pusher element is coupled to the second pusher element via the first transmission device and to a slide via a second transmission device, which can be brought into a position protruding from the housing through a corresponding opening in a faceplate to enclose a latch and / or a bolt of the panic door lock . Here, the first push element is coupled to a first locking rod and the second push element is coupled to a second locking rod. The first transmission device converts the first actuation direction of the first push element into an opposite second actuation direction of the second push element, and the second transmission device converts the first actuation direction of the first push element into a third actuation direction of the slide.

The execution of the opposing box with a first locking via the first locking rod upwards and with a second locking via the second locking rod downwards and without locking on the main locking edge means that embodiments of the opposing box according to the invention have a small backset (DM30) and both for inactive leaves as well as for active leaves and for both DIN directions.

In embodiments of the counter box according to the invention, the movements of the thrust elements and the slide can take place as simple translational movements. Here, a first stroke movement of the first thrust element can be converted into a rotary movement of the gear via the first rack, wherein the rotary movement of the gear via the second rack can be converted into a second stroke movement of the second thrust element, which is directed against the first stroke movement of the first thrust element . Analogously, the second stroke movement of the second thrust element can be converted into a rotary movement of the gearwheel via the second rack The rotational movement of the gear can be converted via the first rack into the first stroke movement of the first push element, which is directed opposite to the second stroke movement of the second push element. In addition, a rotary movement of the gear can be converted via the first rack into the first stroke movement of the first push element and at the same time via the second rack into the second stroke movement of the second push element. Furthermore, the first lifting movement of the first pushing element can be converted into a sliding movement of the slide via the second transmission device, which is perpendicular to the first lifting movement.

In an advantageous embodiment of the opposing box, a drive can be connected to the gearwheel, for example, and can cause the opposing box to be actuated automatically as a function of at least one control signal. The drive can be designed as an electric motor, for example. The drive can drive the gearwheel during automatic actuation, the movement of which can be transmitted simultaneously to the first pushing element and the second pushing element via the first transmission device and from the first pushing element to the slide via the second transmission device. As a result, automatic actuation of the counter box can advantageously also be implemented without actuating the printer follower.

According to the invention, an emergency lock cylinder can be effectively connected to the second push element and causes an emergency actuation of the counter box from the outside. The emergency lock cylinder can act on the second push element via a coupling edge, for example, during the emergency operation, the movement of which can be transmitted via the first transfer device to the first push element and via the second transfer device from the first push element to the slide. As a result, emergency actuation of the counter box can advantageously also be implemented without actuating the printer follower.

In a further advantageous embodiment of the counter box, the actuating element can be designed as a rotary lever with a coupling arm and an actuating arm, which can be connected to the first push element via a slot-and-pin coupling. Here, the coupling arm can be loosely coupled to an actuating element of the printer follower. In addition, when the printer follower is actuated, the actuating element of the printer follower can be coupled to the coupling arm of the actuating means designed as a rotary lever, which can transmit the actuating movement to the first pushing element via the actuating arm and the slotted pin coupling, the movement of which is transferred to the second via the first transmission device Push element and can be transferred simultaneously to the slide via the second transfer device. In an advantageous manner, the actuating element of the printer follower is decoupled from the coupling arm of the actuating means designed as a rotary lever during the automatic actuation of the counter box via the drive or during the emergency actuation of the counter box via the emergency lock cylinder, so that the printer follower does not occur during the automatic actuation and during the emergency operation of the counter box must be moved.

In a further advantageous embodiment of the counter box, the printer follower can be coupled directly to a pretensioned compression spring via a spring arm, the spring force of which counteracts the actuation of the printer follower. This direct coupling between the spring arm and the compression spring enables better power transmission.

In a further advantageous embodiment of the counter box, a guide device can be arranged in a stationary manner in the housing. Here, the slide can be mounted on an upper side of the guide device such that it can slide. The gear wheel can be rotatably mounted on an underside of the guide device. In addition, the first toothed rack and the second toothed rack can each be slidably guided on the underside of the guide device.

In a further advantageous embodiment of the counter box, the second transmission device can comprise a spring-loaded link, which is operatively connected to the first thrust element and is coupled to the slide via a slot-pin coupling and the first actuation direction of the first thrust element in a third actuation direction of the perpendicular to this Slider converts. For this purpose, the slide can have a driver pin which is guided in a guide slot in the link and can transmit a movement of the link to the slide.

In a further advantageous embodiment of the counter case, the slide can have an exchangeable unlocking element at its end facing the panic door lock, which is adapted to the enclosing latch and / or the bolt to be locked. This means that the unlocking element is selected as a function of the enclosing trap and / or the bolt to be locked and then mounted or used on the slide.

The first push element 2 is coupled to a first locking rod, and the second pushing element 3 is coupled to a second locking rod. In addition, the first transmission device 5 converts the first actuation direction of the first push element 2 into an opposite second actuation direction of the second push element 3. The second transmission device 9 converts the first actuation direction of the first push element 2 into a third actuation direction of the slide 12. According to the invention, the first transmission device 5 is designed as a rack and pinion drive and comprises a first rack 5.2 formed on the first push element 2, which is coupled via a gear 5.1 to a second rack 5.3 formed on the second push element 3.

How out Figs. 1 to 6 As can also be seen, the housing 14 of the counter box 1 comprises a base plate 16 and a cover plate 17, which also forms the rear wall of the housing box, and the faceplate 15, which forms a front wall of the housing 14. In the area of the opening in the faceplate 15 through which the slide 12 engages in the unlocked state, a guide device 11 is arranged in a stationary manner in the housing 14 and fastened to the cover plate 17. Here, the slide 12 is mounted on an upper side of the guide device 11 such that it can slide. In addition, on its surface facing away from the guide device 11, the slide 12 has a guide roller 12.2 which is guided in a horizontal guide slot 17.1 made in the cover plate 17 during the sliding movement. The gear 5.1 of the first transmission device 5 is rotatably mounted on an underside of the guide device 11. In addition, the first rack 5.2 of the first thrust element 2 and the second rack 5.3 of the second thrust element 3 are each guided so as to be movable on the underside of the guide device 11. How out Figs. 1 to 6 As can also be seen, the housing 14 of the counter box 1 has a continuous opening into which an emergency lock cylinder 8 can be introduced and fastened. Emergency actuation of the counter box 1 by the fire brigade from the outside is possible, for example, via this emergency lock cylinder 8.

As Figs. 1 to 6 As can also be seen, the second transmission device 9 comprises a spring-loaded, movable S-shaped link 9A, which can be moved against a spring force of a tension spring 10 connected to an upper end of the link 9A and is operatively connected to the first thrust element 2 at a lower end via a connecting pin 2.2 is. In addition, the link 9A has a link pin 9.1, 9.2 at both ends, which are each guided in a vertical guide slot 17.2, 17.3 made in the cover plate 17. Here, an upper link pin 9.1 is guided in an upper vertical guide slot 17.2 and a lower link pin 9.2 is guided in a lower vertical guide slot 17.3. In addition, the link 9A is coupled to the slide 12 via a slot-pin coupling, a corresponding inclined coupling slot 9.3 being formed in an inclined connecting area between the two ends of the S-shaped link 9A. The corresponding driver pin 12.1 is on the surface of the slide 12 facing away from the guide device 11 and engages in the inclined coupling slot 9.3, as a result of which a movement of the link 9A is transmitted to the slide 12. The second transmission device 9 thus converts the first actuation direction, ie a first stroke movement of the first pushing element 2, into a third actuation direction running perpendicular to this, ie, into a horizontal pushing movement of the slide 12.

How out Figs. 1 to 6 As can also be seen, the first thrust element 2 is designed as an upper fork-shaped thrust plate which protrudes upward from the housing 14 and can be connected at the upper end via a first locking rod connection 4.1 to an upper locking rod (not shown). The first rack 5.2 is formed on a first narrower leg of the first push element 2. On a second, wider leg, the first push element 2 is coupled to the actuating means via a pin-slot coupling, which in the illustrated embodiment is designed as a rotary lever 6 with a coupling arm 6.1 and an actuating arm 6.2. In this case, the coupling slot 2.3 is made in the first thrust element 2 and a coupling pin 6.3 is arranged on the actuating arm 6.2 of the rotary lever 6 and engages in the coupling slot 2.3. A foot area of the two legs forms a stop 2.4 which, in the unlocked state of the counter box 1, rests against a stop bolt 16.1 which is fixed to a base plate 16 and is mounted in a cover plate 17 of the housing. Like in particular from Fig. 2 , 4th and 6 As can be seen, a guide pin 2.1 is arranged on the first leg of the first push element 2 above the first rack 5.2, which engages in a vertical guide slot (not visible) in the base plate 16 and thus guides the first push element 2 during a lifting movement in addition to the guide device 11 and secures it against tilting . Below the first rack 5.2, the first push element 2 is connected at the lower end to the link 9A of the second transmission device 9 via the connecting pin 2.2.

How out Figs. 1 to 6 As can also be seen, the second push element 3 is designed as a lower C-shaped push plate which protrudes downward from the housing 14. Here, the second push element 3 can be connected at a lower end arranged below the C-shaped section via a second locking rod connection 4.2 to a lower locking rod (not shown). The second rack 5.3 is formed above the C-shaped section at the upper end of the second push element 3. How out Figs. 1 to 6 As can also be seen, a coupling edge 3.2 is formed at the upper end of the C-shaped section of the second push element 3, which, in the locked state, is arranged in the active area of a non-visible actuating element of the emergency lock cylinder 8 and can interact with it. In addition, the second push element 3 has a guide pin 3.1 in the area of the coupling edge 3.2, which engages in a vertical guide slot (not visible) in the cover plate 17 and thus additionally guides the second push element 3 to the guide device 11 during a lifting movement and prevents it from tilting.

How out Figs. 1 to 6 As can also be seen, the coupling arm 6.1 of the actuating element designed as a rotary lever 6 is loosely coupled to an actuating element 7.1 of the printer follower 7. In addition, the printer follower 7 is coupled directly via a spring arm 7.2 to a pretensioned compression spring 18, the spring force of which counteracts the actuation of the printer follower 7. In the exemplary embodiment shown, the compression spring 18 is designed as a spiral spring which is pushed onto a cylinder screw, which is not specified, and is guided in a guide, which is not specified. The preload of the compression spring 18 can be adjusted via a nut, which is not designated in detail, the spring arm 7.2 of the pressure follower 7 resting below the nut on an upper end of the compression spring 18.

How out Figs. 1 and 2 It can also be seen that in the illustrated locked state of the counter box 1, the first thrust element 2 and the link 9A of the second transmission device 9 are each in an upper end position. As a result, the tension spring 10 connected to the link 9A is compressed. The slide 12 is in the retracted state inside the housing 14. Thereby is a replaceable unlocking element 13, which is at an end of the panic lock facing Slide 12 is arranged, also arranged within the housing 14. The unlocking element 13 can be selected as a function of the bolt to be locked and / or the trap to be locked in of the panic lock (not shown) and can be arranged on the slide 12. The second thrust element 3 is in the illustrated locked state of the counter box 1 in a lower end position. In addition, the actuating element 7.1 of the printer follower 7 rests on the coupling arm 6.1 of the actuating means designed as a rotary lever 6. In this way, actuation of the printer follower 7 can be transmitted to the coupling arm 6.1 via the actuating element 7.1 of the printer follower 7.

When the printer follower 7 is actuated, the coupling arm 6.1 transmits the actuating movement of the printer follower 7, which is executed as a rotary movement, via the actuating arm 6.2 and the slot-pin coupling as the first downward stroke movement to the first pushing element 2. As a result, the first pushing element 2 moves into a lower one End position in which the stop 2.4 of the first thrust element 2 rests on the stop pin 16.1. The first lifting movement of the first pushing element 2 is transmitted via the first transmission device 5 as an opposite, second lifting movement upwards to the second pushing element 3. At the same time, the first downward stroke movement of the first pusher element 2 is transmitted to the link 9A of the second transmission device 9, which converts the downward stroke movement of the gate 9A in the illustrated embodiment into a horizontal sliding movement of the slide 12 to the right.

How out Fig. 3 and 2 It can also be seen that the counter box 1 is in the unlocked state shown after actuation via the printer follower 7. The first thrust element 2 and the link 9A of the second transmission device 9 are each in a lower end position. As a result, the tension spring 10 connected to the link 9A is stretched. The slide 12 is in the locked state and protrudes through the opening in the faceplate 15 from the housing 14. As a result, the unlocking element 13 also protrudes from the housing 14 and can enclose a bolt, not shown, and / or a trap, not shown, of the panic lock, not shown and also unlock the panic lock. The second thrust element 3 is located in shown unlocked state of the counter box 1 in an upper end position. In addition, the actuating element 7.1 of the actuated printer follower 7 rests on the coupling arm 6.1 of the actuating means designed as a rotary lever 6.

In the illustrated embodiment of the counter box 1, an electric motor, not shown, is connected as a drive to the gear 5.1. As a result, an automatic actuation of the opposing box 1 can be effected as a function of at least one control signal. During the automatic actuation, the electric motor drives the gearwheel 5.1, the rotational movement of which is simultaneously transmitted via the first transmission device 5 as the first downward stroke movement to the first push element 2 and as a second upward stroke movement to the second push element 3. In addition, the first downward stroke movement of the first thrust element 2 is transferred to the link 9A of the second transmission device 9, which converts the downward stroke movement of the link 9A in the illustrated embodiment into a horizontal sliding movement of the slide 12 to the right.

How out Figures 5 and 6 It can also be seen that the counter box 1 is in the unlocked state shown after automatic actuation via the electric motor, not shown. Analogous to the actuation via the printer follower, the first push element 2 and the link 9A of the second transmission device 9 are each in a lower end position. As a result, the tension spring 10 connected to the link 9A is stretched. The slide 12 is in the locked state and protrudes through the opening in the faceplate 15 from the housing 14. As a result, the unlocking element 13 also protrudes from the housing 14 and can enclose a bolt, not shown, and / or a trap, not shown, of the panic lock, not shown and also unlock the panic lock. The second push element 3 is in the unlocked state of the counter box 1 shown in an upper end position. In contrast to actuation via the printer follower 7, the printer follower 7 is in its starting position, the actuating element 7.1 of the unactuated printer follower 7 being decoupled from the coupling arm 6.1 of the actuating means designed as a rotary lever 6 and not resting against it.

Even with an emergency operation of the counter box 1 via the emergency lock cylinder 8 from the outside, the counter box 1 can be in the in Figures 5 and 6 shown unlocked state are transferred. During the emergency actuation, an actuating element (not shown) of the emergency lock cylinder 8 acts via the coupling edge 3.2 on the second push element 3. The resulting second upward stroke movement of the second pusher element 3 is converted via the first transmission device 5 into the first downward stroke movement of the first pusher element 2. In addition, the first downward stroke movement of the first thrust element 2 is transferred to the link 9A of the second transmission device 9, which converts the downward stroke movement of the link 9A in the illustrated embodiment into a horizontal sliding movement of the slide 12 to the right. Even after the emergency actuation of the counter box 1 via the emergency lock cylinder 8, the printer follower 7 is in its starting position, the actuating element 7.1 of the unactuated printer follower 7 from the coupling arm 6.1 of the as
Embodiments of the counter box according to the invention for a panic lock 1 do not have any locking on the main locking edge and are only locked upwards and downwards. As a result, embodiments of the counter box according to the invention can be used both for inactive leaves and for active leaves of double-leaf panic doors and for both DIN directions. Furthermore, embodiments of the counter box according to the invention have a small backset and can be opened from the outside by the fire brigade in an emergency. In addition, embodiments of the counter box according to the invention can easily be equipped with motor drives. When combined with conventional panic locks, different gap dimensions can be compensated for using simple screw connections. This is also possible with very little effort in the case of a counter box mounted in the door.
