Description

The invention is based on a lock device for a two-leaf door with an active wing and a passive wing, wherein the lock device is designed according to the preamble of patent claim 1.

As regards the state of the art: From the DE 199 57 999 B4 is such a lock device known for a two-leaf door. The lock device is likewise composed of an active-wing lock device and a passive-wing lock device. The passive wing lock device has a latch lifting device and an electric door opener. The latch lifting device cooperates with the engaging in the locking position of the door in the locking recess of the passive wing lock latch of the active wing lock to dig out the latch from the passive wing lock to unlock the two-leaf door. The electric door opener works with the latch of the active-wing lock together. The passive wing lock device further comprises for locking the passive wing a locking bar means with an upper locking bar and a lower locking bar. Locking devices with the structure according to DE 199 57 999 B4 are often used in practice on double-leaf panic doors. To unlock the two-leaf door push rods or handle bars are mounted on the door wings usually. By manual operation of these bar handles unlocking all locks the lock device, with the aim that panic both wings of the door can be opened, ie the locking bars are retracted, engaging in the passive wing lock latch of the active wing lock is moved back by the latch lifting device in the active wing lock and the electric door opener mechanically unlocked, so that the latch of the active wing lock to open the door from the door opener can move out. A disadvantage of such lock devices is that due to the respective complete unlocking of all locking members basically both wings of the two-leaf door are unlocked and result in disadvantages when entering the door. The two wings are usually designed as under- and sweeping wings, which makes a certain opening and closing sequence required. As you walk through the door, you may experience disability with the door leaves. Furthermore, the cost of re-locking each large and it can also come in particular at the re-locking to incorrect settings and disabilities.

The object of the invention is to provide a lock device for a two-leaf door, which allows a more practicable celebration of the door.

The invention solves this problem with the subject matter of patent claim 1.

The patent claim 1 provides a lock device for a two-leaf door with an active wing and a passive wing, wherein the lock device has an active wing lock device for mounting in or on the active wing and a passive wing lock device for mounting in or on the passive wing.

• eine Riegelaufnahmeausnehmung zur Aufnahme des Riegels der Aktivflügelschlosseinrichtung in einer Verriegelungsstellung und
• eine Riegelaushebeeinrichtung zwecks Entriegelung durch Ausheben des Riegels aus der Riegelaufnahmeausnehmung aus einer Verriegelungsstellung in eine Entriegelungsstellung,
  • wobei die Riegelaushebeeinrichtung eine Betätigungshandhabe aufweist, welche zwischen einer Verriegelungsstellung und einer Entriegelungsstellung verlagerbar ist,
• eine Riegelstangeneinrichtung mit einer oberen Riegelstangeneinrichtung und/oder einer unteren Riegelstangeneinrichtung mit einer Riegelstangenbetätigungseinrichtung, um die obere
  Riegelstangeneinrichtung bzw. die untere Riegelstangeneinrichtung zu betätigen.

The active wing lock device has a lock mechanism with a bolt and possibly also a lock latch or another counter element. The lock mechanism of the active wing lock device is preferably accommodated in a lock housing, the so-called lock case. It is essential that the passive wing lock device has a latch receiving recess, a latch lifting device and a locking bar device. The passive wing lock device comprises in this sense

• a latch receiving recess for receiving the latch of the active wing lock device in a locking position and
• a latch lifting device for unlocking by lifting the latch from the latch receiving recess from a locking position into an unlocked position,
  • wherein the latch lifting device has an actuating handle, which is displaceable between a locking position and an unlocking position,
• a locking bar device with an upper locking bar device and / or a lower locking bar device with a locking bar operating device to the upper
  To actuate locking bar device or the lower locking bar device.

The locking bar actuating device is a part of the lock mechanism of the passive wing lock device. It is preferably accommodated in a lock housing, the so-called lock counter box.

The core of the invention is that the actuating handle of the latch lifting device and the locking bar actuator are switched or switchable that the locking bar means is not forced by actuation of the actuating handle of the latch lifting device and / or actuated by the actuating handle of the latch lifting device, the latch rod device is not forcibly operated in each case , The latch lifting device thus has an actuating handle, which is displaceable between a locking position and an unlocking position, wherein it is provided that this actuating handle of the latch lifting device and the locking bar actuating device are not necessarily connected in operative connection or switchable. This means that upon actuation of the actuating handle of the latch lifting device exclusively the unlocking is carried out by a closing of engaging in the closed position of the two-leaf door in the Riegelaufnahmeausnehmung the passive wing lock device bolt, the locking bar device of the passive wing lock is not necessarily mitbetätigt by the operation of the actuating handle of the latch lifting device. That is, the locking bar actuator of the passive wing lock remains untouched, with the result that the locking bar devices remain in their locking position. This makes it possible to unlock the two-leaf door only so far that a passage of the double-leaf door in the active wing is possible, the passive wing, however, remains in its locked position.

The latch lifting device can be designed in a manner known per se such that the latch moves out of the latch receiving recess. But it can also be designed so that it only releases the latch engaging in the latch receiving recess, z. B. by lateral pivoting away a boundary wall of the latch receiving recess. The latch lifting device can be designed as a purely manually operable actuator or as an electrical actuator.

Preferred embodiments are designed such that the actuating handle of the latch lifting device and the locking bar actuating device are connected in operative connection,
that by actuating the locking bar actuating device in the sense of unlocking the locking bar device, the latch lifting device is forcibly operated in the sense of lifting the latch in the unlocking position, and
but that the locking bar device is not necessarily operated by an actuation of the actuating handle of the latch lifting device in the sense of lifting the latch in the unlocked position.

In preferred embodiments, it may be provided that when the locking bar actuating device is actuated in the opening direction, however, both the upper locking bar and the lower locking bar are brought into their unlocked position are moved as well as the latch lifting device in the unlocked position. This means that upon actuation of the locking bar actuator both the passive wing and the active wing of the double-leaf door are unlocked. After actuation of the locking bar actuator in the opening direction both wings of the double-leaf door can be committed.

The complete locking of the double-leaf door, i. The locking of the passive wing and the active wing is preferably carried out as follows: First, the passive wing of the two-leaf door is brought into its closed position by a user. Then the locking bar actuator is actuated in the locking sense. By this operation of the locking bar actuating device in the locking direction, the upper locking bar and the lower locking bar are moved into their locking position and displaced the latch lifting device in the locking position. The fact that both locking bars are now in the locking position, the passive wing is locked. Now the active wing is spent by the user in its closed position. Because the latch lifting device of the passive wing already occupies its locking position, the two-leaf door is ready for the lock. After locking the active leaf, the double-leaf door is fully locked.

However, if it should be desirable to lock only the passive wing while the active wing remains accessible, the procedure is as follows: First, the passive wing of the double-leaf door is moved to its closed position by the user. Then the locking bar actuator is actuated in the locking sense. Through this operation of the Lock bar actuator in the locking direction, the upper locking bar and the lower locking bar spent in its locking position and displaced the latch lifting device in the locked position. The fact that both locking bars are now in the locking position, the passive wing is locked. However, in order to enable the active wing to remain accessible, it is necessary for the user to actuate the actuating handle of the latch lifting device in order to shift the latch lifting device into its unlocked position. Here, the latch lifting device is moved to its unlocked position, without the upper and lower locking bar are displaced. The double-leaf door is then in a state in which the passive wing is locked, the active wing is not locked due to the unlocked position of the latch lifting device, that is walkable.

In a preferred embodiment, this special relation between the actuating handle of the latch lifting device and the locking bar actuator is achieved in that two separate handles are provided, namely a handle for the latch lifting device and a handle for the latch rod actuator. Embodiments are possible in which these two handles are operatively connected via a special circuit. It is essential, however, that these two handles are also switchable so that they are not in operative connection and thus a separate operation on the one hand the latch lifting device and on the other hand the locking bars is possible.

The actuating handle for the latch lifting device can be switched in two positions. In the first position, the latch lifter is turned off, i. the latch of the active wing lock can engage in the closed position of the two-leaf door in the latch receiving recess of the passive wing lock and thus realize a locking of the active wing. In the second position of the actuating handle of the Begehungsmodus the two-leaf door can be adjusted by committing exclusively on the passive wing. In this position of the handle, which is adjustable in practice as daily position, the latch lifting device is switched in its forward position, so that in the closed position of the door of the latch of the active wing lock is prevented in the latch receiving recess of the passive wing lock on retraction, i. remains in its closed position in the active wing lock. As a result, the active-wing lock remains unlocked, so that each passage of the double-leaf door is possible by passing the passive wing. The two switching positions of the latch lifting device are preferably permanently switched, i. When the actuating handle is switched to the first handle position, there is a switchover of the latch lifting device in the off position and remains maintained until the actuating handle is switched to the second handle position. The latch lifting device is switched by the actuation of the actuating handle in its on position and remains in this position until the actuating handle is switched back to the first handle position.

The latch of the active wing lock can be designed as a conventional latch without inlet slope. However, it can alternatively be designed as a so-called latch bolt, which has an inlet bevel, such as a latch bolt, and acted upon by a spring in the direction of extended position. The latch bolt can assume three positions, namely a first retracted position in the active wing lock, a second extended position and a third extended position. This third extended position is the locking position occupied by the latch bolt when the door is in the closed position. The extended center position is the position occupied by the latch bolt when the active wing is in the open position. This middle position is überdrückbar when closing. In the far extended locking position of the latch bolt may be blocked against pushing back. In order to enable a pushing back through the latch lifting device, a triggering device, preferably be arranged at the free end of the latch bolt, which is actuated via the latch lifting device for lifting the blocking in the blocking position.

The latch lifting device preferably has a latch lifter, which is displaceable between a rearwardly displaced from the active wing wegverlagerten locking position and a vorverlagerten towards the active wing shifted unlocking position. The actuating handle of the latch lifting device, which can be displaced between a locking position and an unlocking position, is preferably connected such that the actuating handle causes a displacement of the latch lifter into its displaced unlocking position upon displacement into its unlocked position.

In particularly preferred embodiments, it is provided that the active wing lock device is designed as a self-locking lock device, the bolt in the closed position of the two-leaf door automatically extends into locking position. If in these embodiments, the latch lifting device is in its forward position due to the daily setting of the actuating handle, the self-locking latch of Aktivflügelschlosseinrichtung is prevented from extending in the closed position of the door, so that a Verrieglung on the active wing lock does not occur as long as the switch position of the actuating handle of the latch lifting in the Daily position is.

In preferred embodiments, it may be provided that the latch of the active wing lock device is designed as a latch bolt.

In particularly preferred embodiments, it is provided that the passive wing lock device has an electric door opener which is mounted in or on the passive wing and cooperates with the latch or the other counter element of the active wing lock device, the electric door opener preferably a movably mounted door opener trap with or without Aushebefunktion and a electrically switchable locking device, via which the door opener latch can be brought into a blocking position and a release position to lock in its blocking position under locking engagement with the latch or the other counter-element active wing in the closed position of the door and in its release position in case of disabling engagement of the latch or the other counter-element to release the active wing from the closed position of the two-leaf door to open the active wing.

In versions with electric door opener, in which the door opener latch has a lifting function, it is possible to lift with the door opener in the release position cooperating with the door latch case counter element of the active wing device. The counter element can be designed as a latch and preferably also as a bolt, in particular as a latch bolt. The active wing lock can thus be designed as a lock with multiple bolts. The one latch is then liftable by the latch lifter and the other latch or latch latch by the lift-open electric striker, i. unlocked.

By equipping the passive wing lock device with the electric door opener, it becomes possible to facilitate entry of the two-leaf door through the active wing that the electric door opener is selectively switched to its release position to open the passive wing from the closed position of the door alone by pressing or pulling to be able to, ie The active wing can be easily pressed to commit without the latch of the active wing lock must be operated by a separate handle. The pressing or mounting of the active leaf is possible when the electric door opener is in its release position and in the locked position, the latch releasing latch lock releasing the latch.

It is especially advantageous to walk over the active leaf in particularly preferred embodiments, which provide that the actuating handle of the latch lifting device and the locking device of the electric striker cooperate in such a way that a displacement of the actuating handle of the latch lifting device in their Entriegelungsstellung causes a circuit of the door opener latch from its blocking position to its release position.

For unlocking the electric door opener may be provided in preferred embodiments, that the electric door opener is electrically switchable via a first switching path and can be unlocked via the actuating handle of the latch lifting device as the second switching path. In a preferred development it can be provided that the electric door opener can be unlocked mechanically via the actuating handle of the latch lifting device.

Embodiments are also possible in which it is provided that the electric door opener is electrically switchable and can be unlocked via a release switch mounted in or on the door opener, preferably manually operable. The unlocking switch can preferably be designed as a manually operable switch, preferably with exclusively mechanical components on the electrically switchable locking device of the door opener in the sense of unlocking, i. Release of the door opener, mechanically acting is switchable. The unlocking switch can be designed in the manner of a known "fingernail switch". The unlocking switch can provide a permanent unlocking position of the door opener in the corresponding switching position.

As regards the operation of the electric door opener, it can be provided that the electrical door opener can be unlocked mechanically by actuating the unlocking switch. Alternatively, it can also be provided that the electric door opener can be unlocked electrically by actuation of the unlocking switch.

Embodiments are also possible in which the electric door opener can not be unlocked mechanically, but the latch can be lifted via a latch lifting device when the electric door opener is in the blocking position.

Embodiments are possible, which provide that the passive wing lock device (20) has a Fallenaufnahmeausnehmung for receiving the lock latch or the other counter element of the active wing lock device in a locking position, and that the passive wing lock device (20) has a latch lifting device with the latch or the other counter element the active wing lock device cooperates for the purpose of unlocking by lifting the latch or the other counter-element from the Fallenaufnahmeausnehmung. In contrast to an electric door opener, the latch lifting device can be designed as a purely manually operable mechanical device. The latch lifting device can be designed so that it moves out the latch or the corresponding counter element from the Fallenaufnahmeausnehmung. But the latch lifting device can also be designed so that it only releases the engaging in the Schlossfallenaufnahmeausnehmung latch or the other mating counter-element, for example, by laterally pivoting away a boundary wall of the Fallenaufnahmeausnehmung. The lock latch lifting device can be designed as a purely manually operable actuator. It may be a non-electrical device as opposed to an electric door opener.

In the following the invention will be described with reference to a drawing. Showing:

Fig. 1

a front view of a two-leaf door, in which an embodiment of the lock device according to the invention is installed.

In the illustrated embodiment, it is a lock device of a two-leaf door. Fig. 1 shows the lock device in the installed state. The illustrated two-leaf door has an active wing 1 with built-active wing lock device 10 and a passive wing 2 with built passive wing lock device 20.

The active wing lock device 10 comprises a lock housing 10g, which is plugged into a receptacle in the active wing 1 as a mortise lock and is covered on the side of the cowl with a face plate. In the cuff plate recesses for the passage of a latch 11 and a bolt 12 are formed. The latch 11 and the latch 12 are formed as a component of the latch mechanism of the active wing lock 10 mounted in the lock housing 10g. They are mounted in the lock housing 10g movable. Both the latch 11 and the latch 12 are displaceable in the illustrated installation position in the horizontal direction. The latch 11 is spring-loaded in the extension direction and has an inlet slope, so that when closing the wing, the latch is suppressed.

The lock mechanism of the active wing lock 10 also has a nut 15n, which is rotatably mounted in the lock housing 10g and serves to connect a handle 15. About the nut 15n, the lock mechanism for actuating the latch 11 and the latch 12 can be actuated. In the illustrated embodiment, the active wing lock device 10 is self-closing, i. in the closed position of the active wing of the bolt 12 moves automatically in its extended locking position. The unlocking of the active wing lock is done by pressing the handle 15 and / or by key operation of a lock cylinder 16, which is part of the lock mechanism of the active wing lock 10.

The passive wing lock device 20 has the same as the active wing lock device 10, a lock housing 20g, which is inserted in a recess in the passive wing 2 as a mortise lock. The lock housing 20 also has a cuff plate on the cuff side, which has receptacles. These recordings are arranged in alignment with the recesses which are formed in the cuff plate of the active wing lock 10 and serve to engage the latch 11 and the bolt 12 of the active wing lock when the double-leaf door is in the closed position. In the lock housing 20g of the passive wing lock 20 receiving recesses are formed in alignment with the Stulpblech-recesses, namely a Schlossfallenaufnahmeausnehmung 21 and a Riegelaufnahmeausnehmung 22. In Schlossfallenaufnahmeausnehmung 21 an electric door opener 21t is arranged, which cooperates with the latch 11 of the active wing lock. In the latch receiving recess 22 engages in the blocking position of the two-leaf door, the bolt 12 of the active wing lock device 10 in its extended locking position.

In the area of the bolt receiving recess 22, a bolt lifting device 22a with a bolt lifter 22ar is arranged. The bolt release 22ar cooperates with the engaging in the blocking position latch 12 of the active wing lock 10. In the forend area of the passive wing lock 20, a hand lever 23 is mounted, which is connected to the latch lifting device 22a and the electric door opener 21t. It serves for manual actuation of the latch lifting device 22a and for actuating the mechanical unlocking of the electric door opener 21t.

The hand lever 23 is formed in the illustrated embodiment in the manner of a Espagnolettes. That the hand lever 23 is concealed in the closed position of the two-leaf door in the rebate area between the passive wing and the active wing. When the active wing 1 is open, the hand lever 23 can be actuated by hand. In the illustrated case, the hand lever 23 has a pivot axis, which is aligned horizontally in the wing plane in the installed position.

The passive wing lock 20 has to lock the passive wing 2 in the closed position on a locking bar means with an upper locking bar means 24o with upper locking bar and a lower locking bar means 24u with lower locking bar. These locking bar devices 24o, 24u can be actuated by means of a handle 25 via a common locking bar actuating device.

The handle 25 is connected in a nut 25n of the passive wing lock 20. By turning the handle 25 is the locking bar means, ie the locking bar of the upper Lock bar means 24o and the locking bar of the lower locking bar means 24u retracted. The locking ends of the locking bars come out of the upper frame-fixed Schließblechausnehmung 24rs and out of the lower bottom-side Schließblechausnehmung 24bs out, wherein the unlocking of the locking bar means takes place. Upon rotation of the handle 25 in the opposite direction, the locking of the locking bar means. In this case, the upper and lower locking bar are extended again so that they again engage in the associated latch plate receptacles 24rs, 24bs, forming the blocking of the passive wing 2.

The trained as Espagnolette actuating lever 23 serves as a day lever. That is, when the active wing 1 is opened and when the passive wing 2 is in the closed position and locked by the locking bar means, the latch lifting means 22a can be operated by manually operating the operating lever 23 so that the latch lifter 22ar is moved in its advanced position and at the same time predetermined sequence of electric door opener 21t is unlocked manually. In this position, the two-leaf door on the active wing 1 is accessible, since the latch 12 is prevented due to the vorverlagerten position of the latch lifter 22ar on an extension into its locked position, so that the self-locking of the active wing lock so not done. At the same time the latch 11 is released due to the unlocked electric door opener, ie the latch is not held by the door latch of the electric door opener 21t in its closed position when the active wing 1 is pressed in the opening direction. This means that in this position of the day lever 23 of the active wing 1 are opened unhindered can while the passive wing 2 remains locked in its closed position by the locking bar device.

In order to fully open the double-leaf door, it is necessary to unlock the latch bar devices 24o, 24u via the handle 25.

Now, when the active wing 1 is brought into the closed position, the latch locks in the door opener 21t and is locked by the locked door latch. The latch 12 of the active wing lock device 10 moves in the closed position of the active wing in its extended locking position under engagement in the latch receiving recess 22 of the passive wing lock. This extension is done automatically due to the self-locking of the active wing lock and is not hindered due to the retracted position of the latch lifter 22ar. The two-leaf door is thus locked in its closed position. To open the two-leaf door, it is necessary to first pull the latch 12 of the self-locking active wing lock 10 by key operation of the lock cylinder 16. The latch 11 can be retracted by actuating the handle 15 or alternatively be unlocked by electrical unlocking the electric door opener.

It is provided that the actuating handle 23 of the latch lifting device 22a and the locking bar actuator 24b are connected in operative connection, that upon actuation of the actuating handle 23 of the latch lifting 22a in the sense of lifting the latch in the unlocked position, the locking bar means 24o, 24u is not necessarily operated. On the other hand, it is envisaged that upon actuation of the locking bar actuating device 24b, 25 in the sense of unlocking the locking bar means 24o, 24u the latch lifting device 22a is forcibly operated in the sense of lifting the latch 12 in the unlocking position.
