Description

The invention relates to a locking arrangement for a double-leaf door of the type mentioned in the preamble of patent claim 1 and a corresponding double-leaf door with such a locking arrangement.

Double-leaf doors with a moving leaf and a fixed leaf as well as a locking arrangement with a full panic function must be able to be opened safely when locked even if the fixed leaf is opened first. So that the locked deadbolt of the active leaf cannot jam in a locking plate of the passive leaf, the deadbolt is moved from the locked position to a locked position by a special mechanism in the strike box of the passive leaf when a handle and/or a panic bar of the passive leaf is actuated. A blockage of the lock bolt must be unlocked beforehand. This is done by actuating an unlocking element, which is usually integrated in the lock bolt and protrudes beyond its face in the direction of the strike box. However, this unlocking element above can be manipulated and reduces the security class of such locks.

From the DE 10 2009 003 860 B4 is a panic lock with a bolt that can be locked forwards and backwards in a bolt displacement direction, in particular by a locking element of a lock cylinder, which is held in the pre-closed position by a tumbler and which carries a trigger that can be displaced in a bolt displacement direction, which, when its front edge is acted upon, causes it to shift into Bolt closing direction releases the tumbler to enable a bolt shift back. In the area of its forehead, the bolt forms a niche that is flanked by its face and is open to the forehead of the bolt, in which the trigger lies, with the niche being open on both broad sides of the bolt and the front edge for releasing the tumbler over the one in the forehead of the bolt lying edge must be shifted into the niche so that the front edge of the trigger is in the niche when the guard locking is released.

From the EP 0 902 141 A1 a panic lock with a housing, a tumbler arranged therein for a bolt and a release lug guided in the closing direction in the bolt is known. When the bolt is locked and locked, the release lug is locked by at least one projection arranged on the tumbler. In addition the release lug and the tumbler are arranged in the same plane, the tumbler having a hook-shaped projection on its edge facing the bolt, which engages in an associated recess of the release lug when the bolt is locked, and a guide lug guided on a cam of the release lug. When the bolt is locked, the release lug protruding beyond a front edge of the bolt is pressed into the bolt when an external handle of the fixed leaf is actuated by a counterbolt arranged in the strike box of the fixed leaf and thereby releases the tumbler from the locked position, so that the bolt is pressed by the counterbolt into the housing can be until the guard locking falls into its locked position.

The invention is based on the object of specifying a locking arrangement for a double-leaf door and a corresponding double-leaf door which, with the same panic functionality, enables improved protection against forced entry and/or burglary. This object is achieved by the features of the locking arrangement for a double-leaf door according to patent claim 1 and by the features of the double-leaf door according to patent claim 7.

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

Embodiments of a locking arrangement according to the invention for a double-leaf door include a lock case with a lock bolt and a blocking device, which secures the lock bolt in a locked state against being converted into a locked state, and a strike case with a locking plate, into which the lock bolt in the locked state is at least partially intervenes. By actuating the strike box to perform a panic function, an unlocking element guided in the lock bolt unblocks the lock bolt and a first actuating element transfers the lock bolt from the locked state to the locked state, in which the lock bolt releases the locking plate. According to the invention, the unlocking element is completely embedded in the lock bolt in the direction of the lock bolt, regardless of the closed state of the lock bolt, with actuation of the lock bolt to execute the panic function, a second actuating element arranged in the lock bolt moving the unlocking element in the direction of blocking and unblocking the lock bolt.

In addition, a double-leaf door with an active leaf and a passive leaf and such a locking arrangement is proposed, which includes a lock case with a lock bolt and a blocking device, which secures the lock bolt in a locked state against being converted into a locked state, and a strike case with a striker plate , in which the lock bolt at least partially engages in the locked state. By actuating the strike box to perform a panic function, an unlocking element guided in the lock bolt unblocks the lock bolt and a first actuating element transfers the lock bolt from the locked state to the locked state, in which the lock bolt releases the locking plate and the door is unlocked.

In embodiments of the present invention, the unlocking element does not protrude beyond the lock bolt in the direction of the strike box, but is embedded in the body of the lock bolt. This advantageously prevents or at least makes it more difficult for the locking bolt to be unblocked without authorization. This has an advantageous effect with regard to burglary protection, so that embodiments of the locking arrangement according to the invention can be classified in a higher security class. An additional advantage is that the unlocking element embedded in the lock bolt does not have to be retracted when the bolt is locked in order to prevent a collision with the locking plate. This additional mechanism does not apply to the integrated unlocking element.

In a preferred embodiment of the double-leaf door according to the invention, the lock case with lock bolt and blocking device can be arranged on the active leaf and the lock case with locking plate can be arranged on the passive leaf. To execute the panic function, a handle and/or a panic bar of the passive leaf can act on the first actuating element via at least one pivoting leaf and actuate the strike box, which then actuates the lock case of the active leaf to unlock the door. A handle and/or a panic bar of the active leaf can act on the blocking and the lock bolt to execute the panic function and directly actuate the lock case. Thus, embodiments of the present invention provide a double-leaf door with a full panic function which, in the closed state, can be unlocked and opened both via the handle and/or panic bar of the active leaf and via the handle and/or panic bar of the passive leaf.

In a preferred embodiment of the locking arrangement according to the invention, the blocking can be implemented as a blocking element which is firmly connected to a movable lock link and can form a stop for the lock bolt when the lock bolt is in the locked state. The unlocking element can, for example, be designed with an actuating bevel, which can lift the blocking element onto an inclined surface of the lock bolt. As a result, an inexpensive and simple mechanism for releasing the blocking of the lock bolt can be implemented in an advantageous manner. To improve guidance, the lock link can have a guide element which rests against a contour of the lock bolt during the transfer of the lock bolt into the locked state and can move the lock link perpendicular to the lock bolt up to a stop. As a result, further movement of the lock bolt beyond the locked state can be prevented in an advantageous manner.

According to the invention, the second actuating element is guided in the first actuating element so that it can move axially. The first actuating element can be moved between an initial position and an end position, with the second actuating element projecting beyond the first actuating element in the direction of the lock bolt until it reaches the end position and acting on the unlocking element via an opening in the lock bolt before the first actuating element hits the lock bolt. This advantageously ensures that the blocking of the lock bolt is canceled before the first actuating element acts on the lock bolt over its entire surface and converts the lock bolt from the locked state to the locked state. Due to the full-surface support of the first actuating element on the end face of the lock bolt, a high degree of security against being pushed back can be implemented in an advantageous manner. Furthermore, the first actuating element can completely accommodate the second actuating element when it reaches its end position, with the end position of the first actuating element corresponding to the closed state of the lock bolt. The first actuating element can be designed, for example, as a slide and the second actuating element can be designed, for example, as an actuating pin, which is in a corresponding Recess in the slide is guided to be axially movable.

In an advantageous embodiment of the double-leaf door according to the invention, the handle and/or the panic bar of the fixed leaf can act, for example via two pivoting levers, on a first actuating element designed as a slide and actuate the strike box. Alternatively, the handle and/or the panic bar of the passive leaf can act on only one pivoting leaf, with the first actuating element being designed as an arm of this pivoting lever and being able to actuate the strike box.

Exemplary embodiments of the invention are explained in more detail below with reference to drawings.

How out Figures 1 to 14 As can be seen, a double-leaf door in the exemplary embodiments shown comprises a moving leaf 3 and a fixed leaf 5 and a locking arrangement 1, 1A. The locking arrangement 1, 1A includes a lock case 10 with a lock bolt 14 and a block, which is designed as a blocking element 16.1 in the illustrated embodiment. The blocking secures the lock bolt 14 in an in Figures 1 to 4 , 11 and 12 , illustrated excluded state against transition to an enclosed state. In addition, the locking arrangement 1, 1A comprises a strike box 20 with a locking plate 22.1, in which the lock bolt 14 engages at least partially in the locked state. By actuating the strike box 20 to perform a panic function, an unlocking element 14.1 guided in the lock bolt 14 unblocks the lock bolt 14, and a first actuating element 24, 24A transfers the lock bolt 14 from the locked state to the locked state, in which the lock bolt 14 Closing plate 22.1 releases and the door is unlocked. The locked state is in Figures 9, 10 and 14 shown.

According to the invention, the unlocking element 14.1 is completely embedded in the lock bolt 14 in the direction of the strike box 20, regardless of the closed state of the lock bolt 14, with the actuation of the strike box 20 for executing the panic function, a second actuating element 24.1, 24.1A arranged in the strike box 20 moving the unlocking element 14.1 in the direction of blocking moves and the blocking of the lock bolt 14 cancels.

How out 1 It can also be seen that the lock case 10 with the lock bolt 14 and blocking device, which are arranged inside a housing 12, is arranged on the active leaf 3. The strike case 20 with the housing 22, whose wall facing the lock case 10 is designed as a closing plate 22.1, is arranged on the fixed leaf 5. The locking plate 22.1 has unspecified openings for engaging the lock bolt 14 and cross latches 7, 9. Here, a first cross latch 7 is arranged above the lock bolt 14, and a second cross latch 9 is arranged below the lock bolt. To execute the panic function, a handle (not shown) and/or a panic bar (not shown) of the fixed leaf 5 act on the first actuating element 24, 24A and actuate the strike box 20, which then actuates the lock case 10. To execute the panic function, a handle (not shown) and/or a panic bar (not shown) of the active leaf 3 act on the blocking and the lock bolt 14 and actuate the lock case 10 directly. Thus, the double-leaf door can be unlocked and opened by the panic function in the closed state both via the handle and/or panic bar of the active leaf 3 and via the handle and/or panic bar of the passive leaf 5.

How out Figures 1 to 14 It can also be seen that the blocking is designed as a blocking element 16.1, which is firmly connected to a movable lock link 16, shown transparently, and forms a stop for the lock bolt 14 when the lock bolt 14 is in the locked state. The lock link 16 is movably mounted in the housing 12 of the lock case 10 and can be moved perpendicular to the sliding movement of the lock bolt 14 to release the blocking. In the illustrated embodiment, the sliding movement of the lock bolt 14 runs horizontally and the movement of the lock link 16 runs vertically upwards. Of course, the person skilled in the art can also use other suitable embodiments for blocking the lock bolt 14 .

How out Figures 1 to 14 It can also be seen that the lock bolt 14 has a bevel 14.2 and a shoulder on its end facing the blocking, on which the blocking element 16.1 rests. The unlocking element 14.1 has an actuating slope at its end facing the blocking, which, when the unlocking element 14.1 moves in the direction of blocking, emerges from an opening at a lower end of the inclined surface 14.2 of the lock bolt 14 and lifts the blocking element 16.1 onto the inclined surface of the lock bolt. This moves the lock setting 16 also up. In addition, the lock link 16 in the illustrated exemplary embodiments has a guide element 16.2, which is also firmly connected to the lock link 16 and, as a result of the upward movement, comes to rest on a sloping contour 16.3 of the lock bolt 14. During the transfer of the lock bolt 14 from the locked state to the locked state, the contour 16.3 of the lock bolt 14 guides the guide element 16.2, so that the lock link 16 is moved further upwards perpendicularly to the lock bolt 14 until a stop (not shown in detail) is reached and the lock bolt 14 enters the locked state. This can advantageously prevent further movement of the lock bolt 14 beyond the locked state.

How out Figures 1 to 10 It can also be seen that the second actuating element 24.1 is designed as an actuating pin in the illustrated embodiment of the locking arrangement 1 and is guided in an axially movable manner in the first actuating element 24, which is designed as a slide. In the exemplary embodiment of locking arrangement 1 shown, the first actuating element 24 designed as a slide is mounted via two pivoted levers 26, each of which is mounted in a housing 22 of the strike box 20 so that it can pivot about a corresponding pivot axis 26.1 and is coupled at one end to the first actuating element designed as a slide 24 , movable between an initial position and an end position. The other end of the pivoting lever 26 is coupled to the handle (not shown) and/or the panic bar (not shown) of the fixed leaf 5 . In addition, the second actuating element 24.1 designed as an actuating pin protrudes beyond the first actuating element 24 designed as a slide until it reaches the end position in the direction of the lock bolt 14. Therefore, before a contact section 24.2 of the first actuating element 24 designed as a slide hits the lock bolt 14, the second actuating element 24.1 designed as an actuating pin can act on the unlocking element 14.1 via an opening in the lock bolt 14 and unblock the lock bolt 14. The second actuating element 24.1 acts on an L-shaped end region 14.5 of the unlocking element 14.1, the end region 14.5 being supported on a return spring 14.4 which acts against the second actuating element 24.1. When it reaches its end position, the first actuating element 24 designed as a slide fully accommodates the second actuating element 24.1 designed as an actuating pin, with the end position of the first actuating element 24 corresponding to the closed state of the lock bolt 14. In the illustrated embodiment, the first actuating element 24 is designed as a slide and the second actuating element 24.1 as an actuating pin.

Of course, those skilled in the art can also use other suitable embodiments for the first actuating element 24 and the second actuating element 24.1.

How out Figures 1 and 2 It can also be seen that the blocking element 16.1 of the lock slide 16 in the illustrated locked state of the double-leaf door secures the locked lock bolt 14 against manual pushing back into the locked state.

How out Figures 3 and 4 is further visible, the counter box 20 is operated in the fixed leaf 5 via the handle not shown and / or the panic bar not shown. As a result, the two pivoted levers 26 are each pivoted about a corresponding pivot axis 26.1 and the first actuating element 24, designed as a slide, moves with the contact section 24.2 and the second actuating element 24.1, designed as an actuating pin, towards the locked and blocked lock bolt 14.

How out Figures 5 and 6 can also be seen, the strike box 20 in the passive leaf 5 is further operated via the handle (not shown) and/or the panic bar (not shown) and the second actuating element 24.1, designed as an actuating pin, in the strike box 20 is operated via the swivel lever 26 and the first actuating element, designed as a slide 24 moves further in the direction of the lock bolt 14 and penetrates into an opening in the lock bolt 14 . As a result, the unlocking element 14.1 is moved against the force of the return spring 14.4 in the direction of the blocking element 16.1, so that it is lifted with the lock link 16. As a result, the lock bolt 14 is released for transfer to the locked state. How out Figures 5 and 6 It can also be seen that after the blocking of the lock bolt 14 has been removed, the first actuating element 24 embodied as a slide rests flat on the end face of the lock bolt 14 with its contact section 24.2.

How out Figures 7 and 8 As can also be seen, the strike box 20 in the passive leaf 5 continues to be operated via the handle (not shown) and/or the panic bar (not shown) and the first actuating element 24, designed as a slide, in the strike box 20 is moved further via the pivoted lever 26 and pushes the lock bolt 14 further back in the direction of the locked state, with the second actuating element 24.1 designed as an actuating pin still protruding into the lock bolt 14.

How out Figures 9 and 10 As can also be seen, the strike box 20 in the passive leaf 5 continues to be operated via the handle (not shown) and/or the panic bar (not shown) and the first actuating element 24, designed as a slide, in the strike box 20 is moved further via the pivoted lever 26 and pushes the lock bolt 14 further back toward the trapped state. Before the end position of the first actuating element 24 designed as a slide is reached, the second actuating element 24.1 designed as an actuating pin is blocked in the strike box 20 while the first actuating element 24 designed as a slide moves further in the strike box 20 towards the end position. As a result, the imposition of the second actuating element 24.1, which is designed as an actuating pin, on the lock bolt 14 is canceled and the unlocking element 14.1 is moved back into the starting position by the return spring 14.4, so that the L-shaped end region 14.5 ends with the end face of the lock bolt 14. The lock bolt 14 snaps into place when locked, so that the fixed leaf 5 and/or the active leaf 3 can be opened.

How out Figures 11 to 14 It can also be seen that the second actuating element 24.1A in the illustrated example of a locking arrangement 1A not according to the invention is designed as an actuating lug which is connected to the first actuating element 24A. In the example shown, the first actuating element 24A and the second actuating element 24.1A are designed in one piece, with the second actuating element 24.1A designed as an actuating lug being formed onto the first actuating element 24A. In the second exemplary embodiment shown, the first actuating element 24A forms an arm of a pivoting lever 26A, which is mounted in a housing 22 of the counter box 20 so as to be pivotable about a corresponding pivot axis 26.1A. In an alternative exemplary embodiment, which is not shown, the second actuating element 24.1A can be designed as a separate component and connected to the first actuating element 24A by means of screws, adhesive bonding, welding, soldering or another suitable connection technique. In addition, the first actuating element 24A can also be designed as a separate component and connected to the pivoted lever 26A by screws, adhesive bonding, welding, soldering or by another suitable connection technique.

By rotating the pivoted lever 26A about the pivot axis 26.1A, one end of the pivoted lever can be pivoted with the first actuating element 24A and the second actuating element 24.1A and a corresponding contact section 24.2A between an initial position and an end position. The other end of the swing arm 26A is coupled to the handle (not shown) and/or the panic bar (not shown) of the fixed leaf 5 . In addition, the second actuating element 24.1A, designed as an actuating lug, projects beyond the contact section 24.2A of the first actuating element 24A until it reaches the end position in the direction of the lock bolt 14. Therefore, analogously to the exemplary embodiment, the second actuating element 24.1A can act on the unlocking element 14.1 via an opening in the lock bolt 14 before the contact section 24.2A of the first actuating element 24 strikes the lock bolt 14 and unblock the lock bolt 14. The second actuating element 24.1A acts analogously to the exemplary embodiment against the force of the return spring 14.4 on the L-shaped end area 14.5 of the unlocking element 14.1.

How out 11 As can also be seen, the blocking element 16.1 of the lock link 16 in the illustrated locked state of the double-leaf door secures the locked lock bolt 14 against being manually pushed back into the locked state, analogously to the exemplary embodiment.

How out 12 is further visible, the counter box 20 is operated in the fixed leaf 5 via the handle not shown and / or the panic bar not shown. As a result, the pivoted lever 26A is pivoted about a corresponding pivot axis 26.1A and the first actuating element 24 moves with the contact section 24.2A and the second actuating element 24.1A designed as an actuating lug towards the locked and blocked lock bolt 14.

How out 13 As can also be seen, strike box 20 in passive leaf 5 continues to be operated via the handle (not shown) and/or panic bar (not shown) and second actuating element 24.1A, designed as an actuating lug, in strike box 20 is further operated via pivoted lever 26A and first actuating element 24 moves in the direction of the lock bolt 14 and penetrates into an opening in the lock bolt 14 . As a result, the unlocking element 14.1 is moved against the force of the return spring 14.4 in the direction of the blocking element 16.1, so that it is lifted with the lock link 16. As a result, the lock bolt 14 is released for transfer to the locked state. How out 13 It can also be seen that the contact section 24.2A of the first actuating element 24A rests against the end face of the lock bolt 14 after the blocking of the lock bolt 14 has been removed.

How out 14 As can also be seen, the strike box 20 in the passive leaf 5 continues to be operated via the handle (not shown) and/or the panic bar (not shown) and the first actuating element 24A in the strike box 20 is moved further via the pivoted lever 26A and pushes the lock bolt 14 further back in towards the closed state. Before reaching the end position of the first actuating element 24A, the second actuating element 24.1A in the strike box 20 pivots out of the opening in the lock bolt 14 while the first actuating element 24 in the strike box 20 moves further towards the end position. As a result, the unlocking element 14.1 is moved back into the initial position by the return spring 14.4, so that the L-shaped end region 14.5 ends with the end face of the lock bolt 14, analogously to the exemplary embodiment. The lock bolt 14 snaps into place when locked, so that the fixed leaf 5 and/or the active leaf 3 can be opened. If required, the lock bolt 14 can have a cutout upwards and/or downwards at the end facing the first actuating element 24A, which increases the range of rotation of the pivoted lever 26A with the first actuating element 24A and the second actuating element 24.1A.

Embodiments of the locking arrangement according to the invention for a double-leaf door advantageously provide improved protection against forced entry and/or burglary with the same panic functionality.
