EP2998475B1 - Day lever for a passive leaf lock - Google Patents

Description

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

As far as the state of the art is concerned: From the DE 199 57 999 B4 and the EP 2 264 268 A2 a lock device constructed in this way for a double-leaf door is known. The lock device is also composed of an active wing lock device and a passive wing lock device. The passive wing lock device has a bolt lifting device and an electric door opener. The bolt lifting device interacts with the bolt of the active wing lock, which engages in the bolt recess of the passive wing lock when the door is in the closed position, in order to lift the bolt out of the passive wing lock to unlock the double-wing door. The electric door opener works with the latch of the active leaf lock together. The passive wing lock device further comprises a locking rod device with an upper locking rod and a lower locking rod for locking the passive wing. Lock facilities with the structure according to DE 199 57 999 B4 are often used in practice on double-leaf panic doors. To unlock the double-leaf door, push rods or handle bars are usually mounted on the door leaves. All locks of the lock device are unlocked by manual actuation of these rod handles, with the aim that both leaves of the door can be opened in the event of a panic, i.e. the locking bars are retracted, the bolt of the active leaf lock engaging in the passive leaf lock is moved back into the active leaf lock by the deadbolt lifting device and the electric door opener is mechanically unlocked so that the latch of the active leaf lock can also disengage from the door opener to open the door. The disadvantage of such lock devices is that, due to the complete unlocking of all locking members, both leaves of the double-leaf door are basically unlocked and there are disadvantages when the door is used. The two wings are usually designed as overlapping and overlapping wings, which requires a certain opening and closing sequence. When going through the door, there may be obstructions in connection with the door leaves. Furthermore, the effort of relocking is great in each case, and incorrect settings and hindrances can occur, especially when relocking.

The object of the invention is to create a lock device for a double-leaf door which enables the door to be entered more practically.

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

Claim 1 provides a lock device for a double-leaf door with an active leaf and a passive leaf, the lock device having an active leaf lock device for mounting in or on the active leaf and a passive leaf lock device for mounting in or on the passive leaf.

  • 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. Die Betätigungshandhabe der Riegelaushebeeinrichtung und die Riegelstangenbetätigungseinrichtung sind dabei als zwei separate Handhaben vorgesehen.

The active wing lock device has a lock mechanism with a bolt and, if necessary, additionally a lock latch or another counter element. The lock mechanism of the active wing lock device is accommodated, for example, in a lock housing, the so-called lock case. It is essential that the passive wing lock device has a bolt receiving recess, a bolt lifting device and a bolt rod device. The passive wing lock device includes in this sense

• a bolt receiving recess for receiving the bolt of the active wing lock device in a locking position and
• a bolt lifting device for the purpose of unlocking by lifting the bolt out of the bolt receiving recess from a locking position into an unlocking position,
  • wherein the bolt lifting device has an operating handle which can be displaced between a locking position and an unlocking position,
• a locking rod device with an upper locking rod device and / or a lower locking rod device with a locking rod actuating device in order to actuate the upper locking rod device and the lower locking rod device, respectively. The operating handle of the bolt lifting device and the locking rod operating device are provided as two separate handles.

The locking bar actuation device is part of the lock mechanism of the passive wing lock device. It is received, for example, in a lock housing, the so-called lock striker box.

The essence of the invention is that the operating handle of the bolt lifting device and the locking rod operating device are switched or switchable in such a way that the locking rod device is not necessarily actuated by actuating the operating handle of the bolt lifting device and / or the locking rod device is not necessarily actuated in every case by actuating the operating handle of the bolt lifting device . The bolt lifting device thus has an operating handle which can be displaced between a locking position and an unlocking position, it being provided that this operating handle of the bolt lifting device and the bolt rod operating device are not necessarily connected or switchable. This means that when the actuating handle of the bolt lifting device is actuated, unlocking takes place exclusively by closing the bolt that engages in the bolt receiving recess of the passive wing lock device in the closed position of the double-leaf door; In other words, the locking bar actuating device of the passive wing lock remains unaffected, with the result that the locking bar devices remain in their locking position. This makes it possible to unlock the double-leaf door only to the extent that it is possible to pass through the double-leaf door in the active leaf, but the passive leaf remains in its locked position.

The bolt lifting device can be designed in a manner known per se in such a way that the bolt moves out of the bolt receiving recess. But it can also be designed so that it only releases the bolt engaging in the bolt receiving recess, e.g. B. by laterally pivoting a boundary wall of the bolt receiving recess. The bolt lifting device can be designed as a purely manually operable actuating device or else as an electrical actuating device.

• dass durch eine Betätigung der Riegelstangenbetätigungseinrichtung im Sinne einer Entriegelung der Riegelstangeneinrichtung die Riegelaushebeeinrichtung zwangsweise im Sinne eines Aushebens des Riegels in Entriegelungsstellung mit betätigt wird, und
• dass aber durch eine Betätigung der Betätigungshandhabe der Riegelaushebeeinrichtung im Sinne eines Aushebens des Riegels in Entriegelungsstellung die Riegelstangeneinrichtung nicht zwangsweise mit betätigt wird.

Preferred embodiments are designed in such a way that the operating handle of the bolt lifting device and the bolt rod operating device are connected in operative connection in such a way that

• that by actuating the locking rod actuating device in the sense of unlocking the locking rod device, the bolt lifting device is forcibly actuated in the sense of lifting the bolt in the unlocked position, and
• but that by actuating the actuating handle of the bolt lifting device in the sense of lifting the bolt in the unlocked position, the locking bar device is not necessarily actuated at the same time.

For example, it can be provided that when the locking rod actuation device is actuated in the opening direction, however, both the upper locking rod and the lower locking rod are brought into their unlocked position and the bolt lifting device is moved into the unlocked position. This means that when the locking bar actuation device is actuated, both the passive leaf and the active leaf of the double-leaf door are unlocked. After actuating the locking bar actuation device in the opening direction, both leaves of the double-leaf door can be accessed.

The complete locking of the double-leaf door, i.e. the locking of the passive leaf and the active leaf, is preferably carried out as follows: First, the passive leaf of the double-leaf door is brought into its closed position by a user. The locking bar actuating device is then actuated in the locking direction. By actuating the locking bar actuating device in the locking direction, the upper locking rod and the lower locking rod are brought into their locking position and the bolt lifting device is shifted into the locking position. Because both locking bars are now in the locking position, the passive wing is locked. The active leaf is now brought into its closed position by the user. Because the latch lifting device of the passive sash is already in its locking position, the double-leaf door is ready for locking. After locking the active leaf, the double-leaf door is completely locked.

However, if it is desired to only lock the passive leaf while the active leaf remains accessible, the following procedure is followed: First, the passive leaf of the double-leaf door is brought into its closed position by the user. The locking bar actuating device is then actuated in the locking direction. By this actuation of the Lock rod actuation device in the locking direction, the upper locking rod and the lower locking rod are brought into their locking position and the bolt lifting device is moved into the locking position. Because both locking bars are now in the locking position, the passive wing is locked. However, in order to enable the active sash to remain accessible, it is necessary for the user to actuate the operating handle of the bolt lifting device in order to move the bolt lifting device into its unlocking position. Here, the bolt lifting device is brought into its unlocking position without the upper and lower locking rods being displaced. The two-leaf door is then in a state in which the passive leaf is locked, the active leaf cannot be locked due to the unlocked position of the bolt lifting device, ie can be walked on.

According to the invention, this special relationship between the operating handle of the bolt lifting device and the bolt rod operating device is achieved in that two separate handles are provided, namely one handle for the bolt lifting device and one handle for the bolt rod operating device. Versions are possible in which these two handles can be switched in operative connection via a special circuit. It is essential, however, that these two handles can also be switched in such a way that they are not in operative connection and that separate actuation of the bolt lifting device on the one hand and the bolt rods on the other hand is possible.

The operating handle for the bolt lifting device can be switched into two positions. In the first position, the bolt lifting device is switched off, i.e. the bolt of the active wing lock can engage in the bolt receiving recess of the passive wing lock in the closed position of the double wing door and thus lock the active wing. In the second position of the actuating handle, the access mode of the double-leaf door can be set exclusively via the passive leaf. In this position of the handle, which in practice can be set as the day position, the bolt lifting device is switched to its advanced position, so that in the closed position of the door the bolt of the active wing lock is prevented from retracting into the bolt receiving recess of the passive wing lock, i.e. in its closed position in Active wing lock remains. As a result, the active leaf lock remains unlocked, so that it is possible to enter the double-leaf door by entering the passive leaf. The two switch positions of the bolt lifting device are preferably permanently switched, i.e. when the operating handle is switched to the first handle position, the bolt lifting device is switched to the switched-off position and is maintained until the operating handle is switched to the second handle position. The bolt lifting device is switched into its switched-on position by actuation of the actuating handle and remains in this position until the actuating handle is switched back to the first handle position.

The bolt of the active wing lock can be designed as a conventional bolt without an inlet bevel. However, it can alternatively also be designed as a so-called latch bolt, which has an inlet bevel, such as a lock latch, and is acted upon by a spring in the direction of the extended position. The latch bolt can assume three positions, namely a first position retracted into the active sash lock, a second extended position and a third far extended position. This third, far extended position is the locking position that the latch bolt assumes when the door is in the closed position. The extended middle position is the position that the latch bolt assumes when the active sash is in the open position. This middle position can be overridden when closing. In the far extended locking position, the latch bolt can be blocked from being pushed back. To enable the bolt lifting device to be pushed back, a release device can be arranged, preferably at the free end of the latch bolt, which can be actuated via the bolt lifting device to unblock the lock in the locked position.

The bolt lifting device has, for example, a bolt lifter which can be displaced between a locking position displaced backwards away from the active sash and an unlocking position displaced forward towards the active sash. The operating handle of the bolt lifting device, which can be displaced between a locking position and an unlocking position, is switched, for example, in such a way that the operating handle, when moved in its unlocking position, causes the bolt lifter to be shifted into its advanced unlocking position.

In exemplary embodiments, it is provided that the active leaf lock device is designed as a self-locking lock device, the bolt of which is in the closed position of the double-leaf door extends automatically into the locking position. If in these versions the bolt lifting device is in its advanced position due to the day setting of the operating handle, the self-locking bolt of the active wing lock device is prevented from extending in the closed position of the door, so that locking via the active wing lock does not take place as long as the switch position of the operating handle of the bolt lifting device is in the Daily position is.

It can be provided, for example, that the bolt 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 interacts with the lock latch or the other counter element of the active wing lock device, the electric door opener being a preferably movably mounted door opener latch with or without a lifting function and a has electrically switchable locking device, via which the door opener latch can be brought into a locked position and into a release position in order to lock the active leaf in the closed position of the door in its locked position with locking engagement with the lock latch or the other counter-element and in its release position when the lock latch is out of locking engagement or the other counter-element to release the active leaf from the closed position of the double-leaf door in order to open the active leaf.

In the case of designs with an electric door opener, in which the door opener latch has a lifting function, it is possible to lift the counter element of the active leaf device that interacts with the door opener latch with the door opener in the release position. The counter-element can be designed as a lock latch and preferably also as a bolt, in particular also as a latch bolt. The active wing lock can thus be designed as a lock with several bolts. One bolt can then be lifted out, i.e. unlocked, by the bolt lifting device and the other bolt or latch bolt by the electric door opener with lifting function.

Equipping the passive leaf lock device with the electric door opener makes it easier to enter the double-leaf door through the active leaf by the fact that the electric door opener can optionally be switched to its release position in order to open the passive leaf from the closed position of the door simply by pushing it open or pulling it open to be able to, ie the active wing can simply be pushed open for entry without the latch of the active wing lock having to be actuated by a separate handle. The active leaf can be pushed open or pulled open when the electric door opener is in its release position and in the locked position the door opener latch holding the lock latch in engagement releases the lock latch.

Particularly advantageously, access via the active leaf is made possible in particularly preferred embodiments, which provide that the operating handle of the bolt lifting device and the locking device of the electric door opener interact in such a way that the operating handle of the bolt lifting device is shifted into its Unlocking position causes the door opener latch to switch from its locked position to its release position.

To unlock the electric door opener, it can be provided in preferred embodiments that the electric door opener can be electrically switched via a first switching path and can be unlocked as a second switching path via the actuating handle of the bolt lifting device. In a preferred development, it can be provided that the electric door opener can be mechanically unlocked via the operating handle of the bolt lifting device.

Versions are also possible in which it is provided that the electric door opener is electrically switchable and can be unlocked via an unlocking switch which is preferably manually operated and is mounted in or on the door opener. The unlocking switch can preferably be designed as a manually operated switch, preferably with exclusively mechanical components, to the electrically switchable locking device of the door opener in the sense of unlocking, i.e. releasing the door opener, which can be mechanically switched. The unlocking switch can be designed in the manner of a “fingernail switch” known per se. The unlocking switch can bring about a permanent unlocking position of the door opener in the corresponding switch position.

As far as the actuation of the electric door opener is concerned, it can be provided that the electric 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 actuating the unlocking switch.

Versions are also possible in which the electric door opener cannot be mechanically released, but the lock latch can be lifted out using a latch lifting device when the electric door opener is in the locked position.

Versions are possible that provide that the passive wing lock device (20) has a latch receiving recess 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 removal device that connects to the lock latch or the other counter element the active wing lock device cooperates for the purpose of unlocking by lifting the lock latch or the other counter-element out of the latch receiving recess. In contrast to an electric door opener, the latch removal device can be designed as a purely manually operable mechanical device. The latch lifting device can be designed in such a way that it moves the lock latch or the corresponding counter element out of the latch receiving recess. The latch lifting device can, however, also be designed in such a way that it only releases the latch engaging in the latch receiving recess or the engaging other counter-element, for example by laterally pivoting away a boundary wall of the latch receiving recess. The lock latch lifting device can be designed as a purely manually operable actuating device. It can be a non-electrical device in contrast to an electrical door opener.

In a preferred development, it can be provided that the actuating device of the bolt lifting device and the latch lifting device interact in such a way that a shift of the operating handle of the bolt lifting device into its unlocking position causes a shifting of the latch lifting device in the sense of unlocking the lock latch or the other counter-element.

Particularly practicable handling results from designs in which it is provided that the actuating handle of the bolt lifting device is designed as an actuating lever that can be arranged in the area of the faceplate of the passive leaf.

In a particularly preferred development, it can be provided that the actuating lever of the bolt lifting device is arranged in the closed position of the double-leaf door in a concealed manner in the rebate space between the active leaf and the passive leaf.

Designs are possible in which the operating lever is designed as a so-called Espagnolette.

Alternatively, however, designs are also possible in which the locking bar actuating device has a handle that is not arranged on the faceplate on the lock, but on the inside and / or on the outside of the door leaf. It can be provided that the locking bar actuating device has an actuating handle which is or can be connected to a socket of the passive wing lock device.

In preferred embodiments it can be provided that the passive wing lock device has a lock housing in which the lock mechanism of the passive wing lock device is arranged, which includes the bolt lifting device and / or the bolt receiving recess and / or the bolt rod actuating device and / or the latch lifting device and / or the latch receiving recess, the electric door opener is arranged outside or inside the lock housing. In a preferred development it can be provided that the electric door opener is arranged inside or outside the lock housing, the electric door opener being designed as a separate door opener module and / or the lock latch receiving recess being designed as part of the door opener, preferably as part of the door opener module.

The invention is described below with reference to a graphic representation. It shows:

Fig. 1

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

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

The active wing lock device 10 comprises a lock housing 10g which is inserted into a receptacle in the active wing 1 as a mortise lock and is covered on the faceplate with a faceplate. Recesses for a lock latch 11 and a bolt 12 to reach through are formed in the faceplate. The lock latch 11 and the bolt 12 are designed as a component of the lock mechanism of the active wing lock 10 that is mounted in the lock housing 10g. They are movably mounted in the lock housing 10g. Both the latch 11 and the bolt 12 can be displaced in the horizontal direction in the installation position shown. The lock latch 11 is spring-loaded in the extension direction and has an inlet slope so that the lock latch can be pushed over when the sash is closed.

The lock mechanism of the active wing lock 10 also has a nut 15n, which is rotatably mounted in the lock housing 10g and is used to connect a handle 15. The lock mechanism for operating the lock latch 11 and the bolt 12 can be operated via the nut 15n. In the exemplary embodiment shown, the active wing lock device 10 is designed to be self-closing, i.e. when the active wing is in the closed position, the bolt 12 automatically extends into its extended locking position. The active wing lock is unlocked by operating the handle 15 and / or by operating a key on a lock cylinder 16, which is part of the lock mechanism of the active wing lock 10.

The passive wing lock device 20, like the active wing lock device 10, has a lock housing 20g which is inserted into a recess in the passive wing 2 as a mortise lock. The lock housing 20 also has a faceplate on the faceplate, which has receptacles. These recordings are aligned with the recesses formed in the faceplate of the active wing lock 10 and serve to engage the lock latch 11 and the bolt 12 of the active wing lock when the double-wing 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 faceplate recesses, namely a lock latch receiving recess 21 and a bolt receiving recess 22. In the lock latch receiving recess 21, an electric door opener 21t is arranged, which interacts with the lock latch 11 of the active wing lock. In the locked position of the double-leaf door, the bolt 12 of the active wing lock device 10 engages in the bolt receiving recess 22 in its extended locked position.

In the area of the bolt receiving recess 22, a bolt lifting device 22a with a bolt lifter 22ar is arranged. The bolt lifter 22ar interacts with the bolt 12 of the active sash lock 10 that engages in the blocking position. In the forend area of the passive wing lock 20, an actuating handle 23 is mounted, which is connected to the bolt lifting device 22a and the electric door opener 21t. It is used to manually actuate the bolt lifting device 22a and to actuate the mechanical unlocking of the electric door opener 21t.

The operating handle 23 is designed in the form of an espagnolette in the illustrated embodiment. That is to say, in the closed position of the double-leaf door, the actuating handle 23 is arranged in a concealed manner in the rebate area between the passive leaf and the active leaf. When the active wing 1 is open, the operating handle 23 can be operated by hand. In the case shown, the actuating handle 23 has a pivot axis which is aligned horizontally in the plane of the wing in the installed position.

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

The handle 25 is connected in a socket 25n of the passive wing lock 20. By rotating the handle 25, the locking rod device, ie the locking rod of the upper locking rod device 24o and the locking rod of the lower locking rod device 24u, are drawn in. The locking ends of the Lock bars come out of the upper frame-fixed strike plate recess 24rs and from the lower bottom strike plate recess 24bs, the locking bar device being unlocked. When the handle 25 is rotated in the opposite direction, the locking bar device is locked. Here, the upper and lower locking rods are extended again, so that they again engage in the associated strike plate receptacles 24rs, 24bs, forming the blocking of the passive leaf 2.

The operating lever 23, designed as an espagnolette, serves as a day lever. That is, when the active sash 1 is open and when the passive sash 2 is in the closed position and locked via the locking bar device, the bolt lifting device 22a can be actuated by manually actuating the operating lever 23 so that the bolt lifting device 22ar is moved in its advanced position and at the same time or in predetermined sequence of the electric door opener 21t is unlocked manually. In this position, the double-leaf door is accessible via the active leaf 1, since the bolt 12 is prevented from extending into its locked position due to the forward position of the bolt lifter 22ar, so that the active leaf lock does not automatically lock. At the same time, the lock latch 11 is unlocked due to the unlocked electric door opener, ie the lock latch is not held in its closed position by the door opener latch of the electric door opener 21t when the active leaf 1 is pushed open in the opening direction. This means that in this position of the day lever 23, the active leaf 1 can be opened unhindered, while the passive leaf 2 remains locked in its closed position by the locking bar device.

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

In order to lock the double-leaf door in the closed position, the passive leaf 2 must be locked in the closed position via the locking bar devices 24o, 24u by means of the handle 25 and then the day lever 23 must be placed in its locked position so that the bolt lifting device 22a is in its position with the bolt lifting device 22ar retracted is moved and the mechanical unlocking of the electric door opener 21t is canceled and thus the electric door opener is switched back to its locking position via its electrical locking device. When the active leaf 1 is now brought into the closed position, the lock latch engages in the door opener 21t and is arrested by the locked door opener latch. In the closed position of the active sash, the bolt 12 of the active wing lock device 10 extends into its extended locking position, engaging in the bolt receiving recess 22 of the passive wing lock. This extension takes place automatically due to the self-locking of the active wing lock and is not prevented due to the retracted position of the bolt lifter 22ar. The double-leaf door is thus locked in its closed position. In order to open the double-leaf door, it is first necessary to retract the bolt 12 of the self-locking active wing lock 10 by operating the key on the lock cylinder 16. The lock latch 11 can be retracted by actuating the handle 15 or, alternatively, can be unlocked by electrically unlocking the electric door opener.

It is provided here that the actuating handle 23 of the bolt lifting device 22a and the locking rod actuating device 24b are connected in operative connection in such a way that when the actuating handle 23 of the bolt lifting device 22a is actuated in the sense of lifting the bolt in the unlocking position, the locking bar device 24o, 24u is not necessarily actuated at the same time. On the other hand, it is provided that when the locking rod actuation device 24b, 25 is actuated in the sense of unlocking the locking rod device 24o, 24u, the bolt lifting device 22a is forcibly actuated in the sense of lifting the bolt 12 in the unlocking position.
