Description

The invention relates to a lock device for a door or a window with at least one wing mounted in a frame according to the features of the preamble of claim 1.

Such lock devices are for example from the EP 2 037 063 B1 known. This lock device has a lock ejector arranged in a lock ejector for a bolt of a door lock. The latch ejector is driven between a first position and a second position. In the first position, the latch of a self-locking door lock engages in a latch receptacle and in the second position, the latch of the door lock is pushed back out of the latch receptacle. As a door lock in the present case, a lock with integrated latch-dependent latching device is used. If the bolt is locked, the latch is locked on the lock side. If the latch is pushed back over the latch ejector, the latch is unlocked on the lock side, so that the door is unlocked and can be opened. Thus, always a lock with lock-side latch-controlled latch locking is necessary.

It is an object of the present invention to provide a lock device for a door or a window, which is structurally simple in construction and inexpensive to manufacture.

According to the invention this object is achieved with a lock device according to the features of claim 1.

The lock device comprises a counter-device with an ejector device which has a motor-driven latch ejector and a motor-driven trap ejector. The motor-driven latch ejector and the motor-driven fall ejector have a common drive motor.

This makes it possible to combine the lock device with such Aktivflügelschlosstypen that have no lock-side latch locking device. In addition, an installation of the lock device is simplified because on the side of the counter device only a single, common drive motor for Riegelauswerfer and Fallenauswerfer is to be connected. In addition, additional components, such as separate door opener to release the latch of the active wing lock, can be dispensed with.

It is envisaged that the lock device has an active-wing lock with a lock housing with lock mechanism received therein. The lock mechanism may comprise in a known manner a bolt and a latch and a lock gear, which cooperates with the bolt and the latch. Further, the lock gear may include a nut for connecting a door handle and a receptacle for a lock cylinder to actuate the latch and / or the latch via a lock cylinder and / or door handle. The counter device has a latch receiving space, in which the latch engages in the closed position of the door to the locking position and a Fallenaufnahmeraum, in which engages the case in the closed position of the door. The latch receiving space and the trap receiving space may be formed separately, d. H. the latch receiving space takes the latch and the trap receiving space takes up the trap. The bolt receiving space and the trap receiving space may alternatively be formed connected, d. H. a common latch receiving space accommodates both the latch and the latch.

In the case of a single-leaf door, the counter-device can be designed or mounted in the context of the door or in a door frame as a striking plate device. In the case of a two-leaf door with active wing and passive wing, the counter-device may be formed and mounted in or on the passive wing as a lock counter-box, or be mounted in a lock counter-box. As an active wing lock, a mortise lock or an overlying lock can be used, wherein the lock is preferably designed as a self-locking lock.

It is preferably provided that the common drive motor is designed as an electric drive motor. The electric drive motor may have a rotary drive or a linear drive.

In particular, it can be provided that the common drive motor has an output, via which both the latch ejector and the Fallenauswerfer can be driven.

In one embodiment it can be provided that a switchable coupling is arranged between the output of the common drive motor on the one hand and the latch ejector and / or the trap ejector on the other hand. The switchable coupling can be designed as an electrically switchable coupling or mechanically switchable coupling, which produces a positive connection between the bolt ejector and the Fallenauswerfer switchable and / or triggers. It is also conceivable that the switchable coupling produces and / or releases a frictional connection between a transmission element connected to the latch ejector and a transmission element connected to the trap ejector. Likewise, the switchable coupling can produce a frictional connection between the latch ejector and a transmission element connected to the trap ejector, or establish and / or release between the trap ejector and a transmission element connected to the latch ejector.

It can further be provided that the fall ejector is releasably connected via the switchable coupling device with the output of the common drive motor and that the latch ejector is permanently connected to the output of the common drive motor. This makes it possible that over the switchable coupling device of the trap ejector is temporarily disconnected from the output of the common drive motor or temporarily engaged. This means that the output of the common drive motor permanently actuates the latch ejector and the latch ejector can preferably be coupled to the output of the drive motor towards the end of the ejector operation or at the beginning of the ejector operation.

In one embodiment it can be provided that the common drive motor and the switchable clutch device can be switched via a control device. The control device can be designed so that when unlocking the door or the door leaf, that is, when moving the ejector device from a basic position to an ejector position, the bar ejector first ejects or pushes the bar back. Only after the bolt has been moved out of the bolt receiving space, the controller switches the coupling means to couple the trap ejector with the output, so that the trap ejects the trap time from the bolt receiving space or the trap receiving space after the bolt. This has the advantage that the case receives a possible preload of the door as long as the bolt is still engaged in the bolt receiving space. As a result, jamming of the bolt is prevented.

In one embodiment, it may be provided that the output of the common drive motor, and the latch ejector and the Fallenauswerfer are connected to each other via a transmission device. The transmission device may comprise, for example, a toothed rack driven by the common drive motor and with these meshing toothed wheels. It is also conceivable that the transmission device is a link mechanism, d. H. Guided tours and guided in the backdrop sliding blocks includes.

In one embodiment, it can be provided that the latch ejector and the trap ejector are rigidly connected to one another, or are connected to one another with positive movement movement. For example, the latch ejector may be connected to the trap ejector via a lever, preferably a drag lever. It can also be provided that the latch ejector and the trap ejector are integrally formed.

In one embodiment, it may be provided that the ejector device with the latch ejector and the trap ejector are arranged in a common housing.

In order to achieve a particularly compact design, it can also be provided that the ejector device with the latch ejector and the trap ejector and the common drive motor are arranged in a common housing.

Further embodiments of the invention are shown in the figures and described below. Showing:

1 a schematic representation of the lock device on a door;

2 a schematic sectional view in the area of the counter box and the active wing lock.

The 1 shows a schematic representation of the lock device according to the invention 1 at a door in a building. The door has a door leaf 11 on, over tapes 13 on a door frame or a door frame 12 is rotatably mounted. The door leaf 11 has an active wing lock 2 on, which is designed as mortise and arranged in a lock pocket of the door leaf. The active wing lock 2 has a lock housing 21 on which a lock mechanism superimposed, which has in a known manner a receptacle for a lock cylinder and a Druckernuss for connecting a door handle and a lock gear to a lock bolt 22 and a trap 23 to press. The trap 23 can be operated via the door handle, ie in the lock housing 21 of the active wing lock 2 be withdrawn. The lock latch 23 is designed as a shooting case, ie as a spring-loaded latch, the basic position of the lock housing 21 protrudes. The bolt 22 is designed as a lock bolt or dead bolt.

On the opposite side of the active wing lock 2 is a counterpart 3 arranged and with the door frame or the door frame 12 connected. The counter device 3 is designed as a striking plate device. The counter device 3 has a latch receiving space 31 in which the latch 22 or the trap 23 for locking the door leaf 11 engage in its closed position. Will the bar 22 in the lock housing 21 withdrawn, for example, by pressing on a Key and a lock cylinder, this is the door 11 unlocked. Ie. the door leaf 11 is then held only by the trap. To open the door leaf is the case in the lock housing on the door handle 21 withdrawn in a known manner, so that the door can be opened.

At the active wing lock 2 it is a self-locking lock. That means that when the opened door 11 is moved to its closed position, the bolt 22 automatically excludes and locks the door. The self-locking of the door lock 2 is triggered by a closing position sensor. The door lock 2 can be designed as an electromechanically self-locking door lock or as a mechanically locking door lock, ie locking device via a spring lock door lock.

The 2 shows a sectional view of the counter device 3 and the active wing lock 2 , The 2 shows the unlocked position of the door leaf. The locking elements of the active wing lock 2 namely the bar 22 and the trap 23 , are in the lock housing 21 moved in. The trap 23 and the latch 22 pass through openings in a forend 24 and can be displayed between their in the lock housing 21 moved back position and one from the lock housing 21 excluded, ie protruding position to be moved. In the locked position, the locking elements engage in the bolt receiving space 31 the counterpart device 3 one.

The counter device 3 includes a housing having an ejector device 38 and one on a downforce 39 with the ejector device 38 connected common drive motor 37 outsourced. The ejector device 38 includes a latch ejector 32 , a trap ejector 33 and a slide plate 34 , The slide plate 34 is parallel to the forend 24 , ie in the leaf level of the 2 up or down, movable. In the slide plate 34 is one with a bar ejector 32 co-operating bolt scenery 35 and one with a trap ejector 33 cooperating case backdrop 36 educated. The case scenery 36 performs a fall curb stone with the trap ejector 33 connected is. The bar scenery 35 leads a bolt Kulissenstein, with the bolt ejector 32 connected is. The case scenery 36 has two angularly against each other inclined gate sections 36a and 36b on. Likewise, the bolt backdrop 35 two angular mutually inclined Riegelkulissenabschnitte 35a and 35b on.

Starting from the in 2 shown ejector position spends the common drive motor 37 the trap ejector 33 and the bar ejector 32 to the basic position by the common drive motor 37 the slide plate 34 moved upwards. In the ejector position shown are both the case 23 as well as the bar 22 from the bolt storage room 31 displaced and the door is unlocked. In the basic position or basic position, both the ejector and the trap ejector are moved back, ie in 2 shifted to the left, so that both the trap 23 as well as the bar 22 into the bolt receiving room 31 can intervene.

In the first movement section of the slide plate 34 first, the fall curb stone is in the upper fall cue section 36a to the left, ie in the direction of the basic position, and moved while the Fallenauswerfer 33 spent to the left. After the trap ejector 33 at the end of the first movement section is in its position corresponding to the home position, the Fallenkulissenstein enters the vertically extending second Fallenkulissenabschnitt 36b one. In the subsequent second movement section, there is no lateral movement of the fall stone block or the fall dropper connected thereto.

The movement of the bar ejector 32 in its basic position is delayed with respect to the movement of the fall ejector 33 , In the first movement section of the slide plate 34 does not move laterally in the first perpendicular section of the bar gate stone. Only when the slide plate 34 so far moved up that the bar gate stone in the second Riegelkulissenabschnitt 35b entry, the opposite of the first bar gate section 35a is inclined, the bolt Kulissenstein and thus the bolt ejector 32 to the left, ie in the direction of its basic position, moves. At the end of the second movement section, ie when the slide plate 34 moved into its upper end position, there is both the latch ejector 32 as well as the trap ejector 33 in the basic position, ie in the opposite to the in 2 position shown shifted to the left position. Both the bar ejector 32 as well as the trap ejector 33 in the basic position release the bolt receiving space so that both the trap 23 as well as the bar 22 can engage in the bolt receiving space for locking the door leaf.

Ejecting the locking elements 22 . 23 takes place in mutatis mutandis reverse direction. Starting from the basic position is via the common drive motor 37 and the downforce 39 the slide plate 34 Move down from its upper position. About the first bar gate section 35b This is initially the bar ejector 32 to the right into the in 2 shown position moves. During this movement section, the falling cusp stone runs in the vertical section the fall scene 36b so that the trap ejector still remains in the home position. Only after the bolt ejector the bolt 22 has pushed back and his in 2 has reached shown ejector position, the Fallenkulissenstein enters the second section 36a the case scenery. Only in this second section is the Fallenkulissenstein and thus the Fallenauswerfer 33 to the right into the in the 2 shown ejector position moves.

This means that when the door is unlocked, the ejector device first actuates the latch via the latch ejector and, thereafter, the trap ejector 33 the trap 23 actuated. This has the advantage that in case of a possible preload on the door, for example, by a strong wind load, the trap remains engaged until the bolt 22 completely into the active wing lock 2 pushed back. Only then will the trap fall over the trap ejector 33 actuated. This will jamming the bolt 22 effectively prevented.

Furthermore, the unlocking can be done in two steps. In a first step, the bar ejector throws 32 the bolt 22 out. The common motor stops after completion of the first movement section. The trap 23 still remains engaged with the latch receiving space and keeps the door in its closed position. Subsequently, either the door can be locked again to the first movement section by reversing the direction of rotation of the common drive motor and thus the latch ejector 32 is moved back to its normal position or it can connect the second movement section offset in time by the common drive motor 37 the slide plate 34 pressed upwards into its end position and thus also the Fallenauswerfer 33 to eject the trap 23 drives.

About a control device, the movement can be controlled specifically. For that are on the slide plate 34 and / or at the output of the engine 39 Sensors provided a position of the slide plate 34 monitor.

By means of a control device, the movement sequence and the unlocking process of the door can thus be controlled in a targeted manner. So can optionally via the common drive motor 37 either just the bar 22 can be ejected or it can both the latch 22 as well as the trap 23 be ejected. A daytime circuit or permanent open circuit can also be implemented via the control device, for example, by the control device, the common drive motor 37 so controls that only the bolt ejector 32 in his ejector position, ie in the in the 2 shown position, is driven and intervention of the trap is possible. As a result, locking the door over the bolt is effectively prevented. This so-called. Tagschaltung is for example for medical practices or kindergartens, where a door while in the closed position on the trap 23 held, but not over a bolt should be additionally locked, beneficial.
