Description

Technical Field

[0001] The present invention relates to a locking device for a door leaf of a door assembly having the features of the preamble of claim 1. Furthermore, the present invention relates to a door assembly having the features of the parallel claims, comprising a frame and at least one door leaf pivotally supported at the frame. Background Technology

[0002] Locking devices of the type mentioned above are known in the prior art, for example, from EP 3 748 109A1. This discloses a locking device having a lock housing, a main lock fastened to the lock housing, and a plurality of secondary locks fastened to the lock housing, the secondary locks being coupled to the main lock via a drive rod. This allows for secure and reliable locking. Installation at the door leaf is typically achieved using a fully pre-installed locking device. This necessitates corresponding milling grooves in the door leaf. For maintenance or replacement of the lock components, the locking device needs to be disassembled and, if necessary, at least partially disassembled.

[0003] EP 3 045 624A1 discloses a lock with a latch element that can be installed on a door leaf, wherein the latch element is operable via a lock mechanism. The lock also has an interface for connecting an actuating latch device to a latch rod. The interface has a connecting element for connecting to the lock mechanism and an opening provided in the lock housing, wherein a transmission element passes through the opening and connects to the connecting element when the actuating latch device is connected. Disassembly is required to disengage the actuating latch device from the lock. Summary of the Invention

[0004] The purpose of this invention is to simplify the installation and maintenance of locking devices. Particularly desirable is the ability to easily couple one or more drive bolts to the drive mechanism of the locking device and decouple them when necessary.

[0005] The present invention achieves the objective by means of a locking device having the features of claim 1.

[0006] The locking device configures and / or determines the door leaf for the door assembly. The locking device has a lock housing, a drive mechanism fastened to the lock housing, and at least one drive rod extending in a longitudinal direction (either the longitudinal direction of the lock housing or the longitudinal direction of the drive rod). The at least one drive rod is actuated by the drive mechanism and can be displaced in the longitudinal direction when actuated by the drive mechanism.

[0007] At least one drive lever is secured with a coupling device for coupling the drive latch. Each coupling device has a receiving portion into which the drive latch can be introduced via an end section. The coupling device and the drive latch are configured such that when the end section is introduced into the receiving portion, the drive latch is locked to or secured at the coupling device. In other words, when the end section is pushed into the receiving portion, the drive latch is locked at or to the coupling device (establishing a form-fitting connection in the form of a locking connection).

[0008] The proposed locking device allows for automatic coupling or connection of the drive bolt at or with the coupling device, more precisely, without the need for tightening or other installation steps. Coupling is achieved simply by plugging the drive bolt and coupling device together. This simple installation reduces installation time. Because the coupling motion (introduction or plugging together) is relatively simple, the installation of the locking device can be significantly automated more easily.

[0009] The drive bolt is opened in the longitudinal direction by means of a receiving portion that can be introduced by the end section, preferably only in the longitudinal direction away from the drive mechanism.

[0010] Within a preferred design, the coupling device can be configured such that the actuating bolt at or coupled to the coupling device can be reversibly disengaged. In other words, the actuating bolt can be reversibly disengaged from the coupling device at or after locking with the coupling device. This facilitates the removal or maintenance of one or more actuating bolts.

[0011] Advantageously, the coupling device can have a housing in which a locking element is movably supported for coupling the drive bolt, wherein the locking element can shift between a coupled position and a released position, in which the locking element engages in a receiving portion along the shifting direction for coupling with the drive bolt, and in the released position, the locking element releases the receiving portion for decoupling the drive bolt (the locking element at least partially or completely shifts away from the receiving portion in the released position). The locking element enables a structurally simple and stable coupling of the drive bolt at the coupling device. If the end section or insertion section of the drive bolt is introduced or inserted into the receiving portion, the locking element can be introduced into the coupled position. The locking element can then engage in an opening formed in the end section of the drive bolt or in a through portion formed therein for coupling the drive bolt.

[0012] Specifically, the displacement direction of the locking element is perpendicular to the longitudinal direction, and at least one drive rod extends along said longitudinal direction. Independently, the coupling device is preferably configured such that the locking element is displaced toward the drive rod in the released position and / or displaced away from the drive rod in the coupled position. In other words, the locking element is farther away from the drive rod in the coupled position compared to the released position.

[0013] Suitably, the locking element can be preloaded into the coupling position by means of a spring element, particularly by means of a preferably helical pressure spring, i.e., preloaded particularly away from the drive rod. Thus, the locking element is reliably held in the coupling position. Furthermore, it becomes advantageous for the drive latch to automatically lock or engage at the coupling device. A spring receiving portion or spring receiving section can be constructed in the housing of the coupling device for housing the spring element. The spring element can be fastened at one end to the locking element and supported at the other end at the housing section or the drive rod, where the coupling device is fastened.

[0014] Within a preferred design, the locking element may have an introduced bevel, allowing it to be displaced from the coupled position toward the released position by introducing the end portion of the drive bolt into the recess. This facilitates automatic coupling of the drive bolt at the coupling device. The locking element can then be lifted from the coupled position by introducing or pushing in the end portion of the drive rod.

[0015] Advantageously, the locking element may have a first profile feature at its distal end (towards the receiving portion of the coupling device), wherein the receiving portion may have a second profile feature corresponding to, and particularly complementary to, the first profile feature, wherein the first and second profile features engage with each other when the locking element is located in the coupling device. Therefore, "anti-tilting" can be achieved because by engaging the first and second profile features, "tilting" of the locking element during the introduction and / or withdrawal of the drive bolt can be prevented as much as possible. The first profile feature (locking element) may be configured as a recess having an edge-side wall section extending out of the recess. The second profile feature may be configured as a protrusion having an edge-side recess, for example, in a U-shape.

[0016] Suitably, the locking element may have a threaded section at its proximal end (towards the drive rod), and the drive rod and / or lock housing may each have a through portion aligned with the threaded section, such that an operating element having a mating threaded section corresponding to the threaded section can be guided through the through portion and coupled to the threaded section. This allows the locking element to be operated "from the outside" via the drive rod and / or lock housing. Thus, the locking element (through the lock housing and / or drive rod) can be operated by means of the coupled operating element, for example, shifting from a coupled position to a released position. This allows the drive bolt to be disengaged or removed while the locking device is in or installed in the door assembly (without requiring removal or disassembly of the locking device).

[0017] Specifically, the threaded section can be configured as a hole with internal threads and / or the operating element with a mating threaded section can be configured as a bolt with external threads. This facilitates the compact, structurally simple, and stable coupling of the operating element to the locking element.

[0018] Preferably, a threaded hole can be formed in the bolt-like section, preferably extending from the locking element, wherein the spring element surrounds the bolt-like section. This allows for a particularly compact arrangement of the spring element, especially a compression spring, and the threaded hole. Thus, a bolt with external threads can be guided through the free internal space (“eye”) of the spring element and screwed into the threaded hole.

[0019] Specifically, the locking element may have a cross-section defined by two opposing, preferably parallel, flat sides and two opposing, narrow sides connecting the flat sides, wherein the narrow sides have rounded contours. This facilitates improved support of the locking element within the housing of the coupling device, wherein the housing may be configured to have relatively low wall strength. The rounded contours of the narrow sides may be particularly arcuate or semicircular, respectively. A locking element guide opening may be formed in the housing of the coupling device, the locking element guide opening having at least a partial cross-section complementary to the locking element. A spring receiving section for a spring element may be formed in the flat side of the locking element guide opening.

[0020] Within a preferred design, the receiving portion can be located at the coupling device such that the drive bolt coupled to the coupling device is offset away from the drive rod on the side of the drive rod opposite to the lock housing. This allows the drive bolt to be offset relative to the drive rod or the lock housing. Thus, a concealed arrangement of the drive bolt is feasible (the drive bolt is placed inside the door panel, for example, in a laterally closed drive bolt channel within the door panel that is open at the ends).

[0021] Suitably, the housing of the coupling device may have a flange section for fastening the coupling device to the drive rod, particularly by riveting or screwing. This allows the coupling device to be structurally simple and reliably fastened to the drive rod.

[0022] Advantageously, the drive latch may have an end section (insertion section), a connecting section, and / or a latch section. The end section (insertion section) is used to couple the drive latch to a coupling device. The latch section is used to lockably engage with the door frame (the latch section extends from the door leaf or sash at the upper side) or lockably engage with the ground (the latch section extends from the door leaf or sash at the lower side). The latch section may have a greater thickness than the end section and / or the connecting section. The connecting section is located between the end section (insertion section) and the latch section and connects the end section to the latch section. One or more recesses or through sections may be formed in the end section (insertion section) for engaging with a locking element.

[0023] The latch segment and the connecting segment may each have (corresponding) teeth, and the two segments can be coupled to each other or to each other by means of said teeth. This contributes to a particularly stable coupling between the latch segment and the connecting segment. Optionally, the latch segment and the connecting segment can be configured such that they are coupled to each other in different axial overlaps. This allows for setting the length of the drive latch in such that the latch segment and the connecting segment can be coupled by different (axial) overlaps. Alternatively, the latch segment and the connecting segment can be securely connected to each other, for example, by riveting.

[0024] Within a feasible design scope, the drive device for driving at least one drive rod can be an electric motor driver.

[0025] Similarly, it is also conceivable that the drive mechanism is configured as a bolt lock with one or more latch elements (latch and / or bolt), wherein the bolt lock has a lock nut and / or locking post, and the bolt lock drive mechanism can be operated via at least one or both of the aforementioned components. When the lock drive mechanism is driven, one or more drive levers are also driven. The bolt lock can (can be described as an "active lock") be located at the active door leaf (access door leaf).

[0026] The drive mechanism can also be configured as a passive lock with a latch receiving portion and / or a bolt receiving portion, which is preferably equipped with a latch ejector and / or a bolt ejector. The passive lock can be operated by means of an operating device such as a handle, and the lock transmission mechanism of the passive lock is driven by it. One or more drive levers are also driven when the lock transmission mechanism is activated.

[0027] The locking device may optionally have an introduction or centering aid. The introduction and centering aids may be disposed and / or secured in the drive lever channel of the door device. The introduction or centering aids may be respectively fixedly disposed and / or secured in the bolt channel, wherein the introduction or centering aid has a through portion for driving the bolt. The through portion of the introduction or centering aid may widen, preferably tapering, from the cross-section of the drive bolt (the tapered introduction section of the through portion), opposite to the introduction direction. Thus, the drive bolt to be introduced can be centered by passing through the described introduction section into the through portion via its free end (end section). This facilitates the introduction of the drive bolt into the receiving portion of the coupling device.

[0028] The receiving portion of the coupling device can be configured as a slit or a receiving slit for the end section. Regardless of its orientation, the receiving portion of the coupling device can have an introduction bevel. The introduction bevel can be widened opposite to the direction of the introduction of the drive bolt, preferably tapered (the bevel of the opening edge of the receiving portion). This facilitates the introduction of the drive bolt (end section) into the receiving portion of the coupling device, more precisely, without the aid of additional components (the number of components in the locking device can be kept to a minimum).

[0029] As indicated above, the locking device can have two drive rods, two coupling devices, and two drive bolts. Therefore, the locking device can be configured as a locking device for a door leaf of a door assembly, the locking device having a lock housing, a drive device fastened to the lock housing, and two drive rods extending along the longitudinal direction (lock housing / drive rod -), wherein the drive rods can be driven by the drive device and can be displaced along the longitudinal direction when driven by the drive device, wherein coupling devices for coupling the drive bolts are fastened to each of the two drive rods, wherein each coupling device has a receiving portion, and one of the drive bolts can be introduced into the receiving portion by means of an end section, wherein the coupling device and the drive bolt are respectively configured such that when the end section is introduced into the corresponding receiving portion, the corresponding drive bolt is locked and coupled to the coupling device.

[0030] The locking device can be optionally configured as an actuated bolt lock or as a multi-point locking device.

[0031] The aforementioned objective is achieved by a door device having the features of the parallel claims. The door device has a frame and at least one door leaf pivotally supported at the frame. Each door leaf includes a locking device having one or more of the aforementioned aspects. Reference is made to embodiments of the locking device in relation to this, considering the advantages achievable by this.

[0032] Door installations can have one door leaf (single-leaf door installation) or two door leaves (double-leaf door installation). In double-leaf door installations, only one door leaf can be equipped with a locking device, which can be either a passage door leaf (active door leaf) or a fixed door leaf (passive door leaf). The design of a fixed door leaf with a locking device allows the fixed door leaf (drive latch) to lock at its hinge engagement side. This contributes to a stable locking of the passage door leaf at the fixed door leaf. The design of a passage door leaf with a locking device is beneficial for sealing between the passage door leaf and the frame, especially in the case of doors with a height greater than 2 meters (high wind loads).

[0033] Similarly, in a two-door assembly, each door leaf is equipped with a locking device. This contributes to high security and a high degree of sealing between the door leaf and the door frame. The drive mechanism of the locking device for the fixed door can be configured as a passive lock, which has a latch receiving portion and / or a bolt receiving portion, and optionally may have a latch ejector and / or a bolt ejector. The drive mechanism of the locking device for the passage door leaf can be configured as an active lock with a latch and / or a bolt, which, in the closed position of the door leaf, can be aligned with and enter the latch receiving portion and / or bolt receiving portion of the passive lock, respectively. Thus, the active and passive locks can be configured as described above.

[0034] Within a preferred design, the door leaf may contain a recess for the drive mechanism, a recess for the lock housing, at least one additional recess for the coupling mechanism, and / or at least one bolt channel for driving the bolt (for concealed installation). This facilitates the integration of locking device components into the door leaf. Consequently, the locking device components can be integrated into the door leaf, protecting them from environmental influences and human damage.

[0035] The present invention is also achieved by a method for installing a locking device at a door device.

[0036] This relates to a method for installing a locking device at a door assembly, wherein the locking device has, in particular, one or more locking devices as described above, and the door assembly has at least one frame and a door leaf pivotally supported at the frame, wherein the method comprises the following steps:

[0037] a. Introduce the drive unit into the recess for the drive unit, and introduce at least one coupling device into at least one additional recess, and insert the lock housing into the recess for the lock housing at the door leaf;

[0038] b. Screw the lock case at least partially onto the door;

[0039] c. Push at least one drive bolt into a bolt channel formed at the door leaf for driving the bolt; and

[0040] d. Introduce the end portion of the drive latch into the coupling device, wherein when the end portion is introduced into the receiving portion of the coupling device, the drive latch is coupled to the coupling device by locking.

[0041] If the locking device has two coupling devices and two latch channels at the door leaf, then the two drive latches can be pushed into the latch channels formed at the door leaf for driving the latches (one drive latch per drive channel). The end segments of the drive latches can then be introduced into the corresponding coupling devices, wherein when the end segments are introduced into the receiving portions of the corresponding coupling devices, the corresponding drive latches are locked and coupled to the coupling devices.

[0042] Step a. above can be described, in a synonymous sense, by the feature “positioning the locking device at the door leaf”, which includes the features of step a.

[0043] Before performing step a., at least one door leaf may be provided, wherein the door leaf has a recess for the drive mechanism, a clearance for the lock housing, at least one additional clearance for the coupling mechanism, and / or at least one latch channel for driving the latch (for concealed installation). Where the locking device in question has two coupling mechanisms, two additional clearances for the coupling mechanisms are formed at the door leaf. Where two drive latches are provided, two latch channels for driving the latches are formed at the door leaf. Attached Figure Description

[0055] Figure 1a A door assembly is shown, generally designated by reference numeral 200. The door assembly 200 has a frame 202, a first door leaf 204 pivotally supported at the frame 202, and a second door leaf 206 pivotally supported at the frame 202. Door leaves 204 and 206 are pivotally supported at the frame 202 by means of door hinges 208 and 210, respectively. In this example, the first door leaf 204 is equipped with a locking device 10 (in... Figure 1a (Indicated by dashed box 10). Locking device 10 is described more precisely below.

[0056] Figure 1b The first door leaf 204, equipped with the locking device 10, is shown observably from the end side 205 of the first door leaf. A portion of the locking device 10, particularly its lock housing 12, is visible there.

[0057] Figure 2a , Figure 2b and Figure 3 Different views of the locking device 10 in its independent positions are shown. The locking device 10 has a lock housing 12 and an actuation device 14 fastened to the lock housing 12. In the example, the actuation device 14 is configured as a bolt lock 15, which has a lock transmission device 16 (not shown in detail), a latch 17, a bolt 18, and a clamping nut 19.

[0058] Furthermore, in the example, the locking device 10 has two drive rods 21 and 22 extending respectively along a longitudinal direction 20. The longitudinal direction 20 extends along or parallel to the lock housing 12. The drive rods 21 and 22 can be driven by a drive device 14 and can be displaced along the longitudinal direction 20 when driven by the drive device 14. Specifically, the lock transmission device 16 can be driven by operating the clamping nut 19, wherein, for example, the latch 17 also has corresponding displacement of the drive rods 21 and 22.

[0059] Drive rods 21 and 22 are coupled to drive mechanism 14, particularly to its lock transmission mechanism 16, and are guided at lock housing 12 by means of guide element 23 coupled at lock housing 12. In the example, guide element 23 engages with corresponding recesses 24 in drive rods 21 and 22.

[0060] Coupling devices 25 for coupling the driving bolts 26 and 27 are fastened at the drive rods 21 and 22 respectively (see...). Figure 1b , Figure 9a or Figure 9b ).

[0061] The construction and operation of the coupling device 25 are particularly referenced. Figures 4a to 7d More accurately, and more precisely, based on the example description of drive rod 22. Drive rod 21 and its coupling device 25 are similarly constructed.

[0062] The coupling device 25 has a housing 25' with a flange section 28, through which the housing 25' is fastened to the drive rod 22. In the example, the housing 25' is thus fastened to the drive rod 22 via two fastening points 29, such as by screwing or riveting (shown schematically only).

[0063] The housing 25' of the coupling device 25 includes a receiving portion 30 for the end sections of the driving latches 26 and 27. In this example, the receiving portion 30 is configured as a receiving slot 31, which is open outward only towards its inlet opening 32. The receiving portion 30 has an inlet bevel 32' that tapers outward in the opposite direction to the inlet direction of the driving latches 26 and 27 (i.e., outward from the inlet opening 32). Furthermore, the housing 25' includes a locking element guide opening 33, which is open towards the flange section 30 (i.e., "upward" towards the drive rod 22) and leads into the receiving portion 30.

[0064] In the locking element guide opening 33, the locking element 50 is movably supported for coupling the drive bolts 26, 27. The locking element 50 can be in the coupled position (see...) Figure 4b The locking element 50 is shifted between a coupled position (or 4c) and a release position (not shown), in which the locking element 50 engages in the receiving portion 30 for coupling with the drive bolts 26, 27, and in the release position, the locking element 50 releases the receiving portion 30 to decouple the drive bolts 26, 27 (the locking element 50 is at least partially or completely removed from the receiving portion 30 in the release position). The coupling device 25 is configured such that the locking element 50 is shifted further away from the drive rod 22 in the coupled position compared to the release position.

[0065] The locking element 50 is preloaded into the coupled position, i.e., preloaded away from the drive rod 22, by means of a spring element 70, which in this example is a helical pressure spring 71. In this example, the spring element 70 is supported at one end of the drive rod 22 and at the other end of the locking element 50. In this example, a spring receiving section 35 is formed at the locking element guide opening 33 (see...). Figure 4c or Figure 5b The spring receiving section widens the cross-section of the locking element guide opening 33, so that the spring element 70 can be disposed in the locking element guide opening 33.

[0066] The locking element 50 has an introduction bevel 53 at its distal end 51. Thus, by introducing the end portions of the drive bolts 26, 27 into the recess 30, the locking element 50 can be positioned from the coupled position (see [reference]). Figure 4c The part is shifted in the direction of the release position (the release position is not shown).

[0067] The locking element 50 has a first profile feature 54 at its distal end 51 (see Figure 4c The first contour feature 54 is configured as a recess 55, the recess having an edge-side wall segment 56 extending out of the recess 55 (see...). Figure 6b or Figure 6dThe receiving portion 30 has a second contour feature 57, which corresponds to and is complementary to the first contour feature 54 in this example. The second contour feature 57 is configured as a protrusion 58 having an edge-side recess 59, which is U-shaped in this example (see...). Figure 7d When the locking element 50 is in the coupled position (see...) Figure 4c The first contour feature 54 and the second contour feature 57 are joined together to achieve anti-tilting.

[0068] The locking element 50 has a threaded section 60 at its proximal end 52. The threaded section 60 is configured as a hole 61 with internal threads 62. In the example, the hole 61 with internal threads 62 is formed in a bolt-shaped section 63 extending from the locking element 50, wherein the spring element 70 surrounds the bolt-shaped section 63 in an assembled state (see [link]). Figure 4c ).

[0069] The drive rod 22 and the lock housing 12 each have through portions 12' and 22' aligned with the threaded section 60 (see, for example, see...). Figure 2a , Figure 2b and Figure 3 Therefore, an operating element 80 having a mating threaded section 81 corresponding to the threaded section 60 can be guided through the through portions 12', 22' and coupled to the threaded section 60. In the example, the operating element 80 having the mating threaded section 81 is configured as a bolt 82 having an external thread 83 (see...). Figure 2a and Figure 2b Therefore, by means of the operating element 80, the locking element 50 can be operated through the lock housing 12 and the drive lever 22, for example, by shifting from the coupled position to the released position. Thus, the drive bolts 26, 27 can be decoupled from the coupling device 25 "from the outside" without disassembling the locking device 10.

[0070] The locking element 50 has a cross-section defined by two flat sides 64 opposite to each other, preferably parallel to each other, and two narrow sides 65 opposite to each other connecting the flat sides 64, wherein the narrow sides 65 have rounded, semi-circular profiles in the example (see...). Figure 6d The locking element guide opening 33 at least partially has a cross-section complementary to that of the locking element 50 (see...). Figure 7d A spring receiving section 35 for the spring element 70 is formed in the flat side 84 of the locking element guide opening 33.

[0071] The receiving portion 30 is provided at the coupling device 25, such that the drive latches 26 and 27 coupled to the coupling device 25 are staggered away from the drive rod 22 on the side of the drive rod 22 away from the lock housing 12 (see...). Figure 9c ).

[0072] The structure of the drive latch 26 is described below. The drive latch 26 has an end section 26' (insertion section), a connecting section 26”, and a latch section 26”' (see [reference]). Figure 9b End section 26' is used to couple the drive latch 26 to the coupling device 25. Latch section 26"' is used to lockably engage with the door frame 22 (see...). Figure 1a and Figure 1b The connecting section 26” is located between the end section 26’ and the latch section 26”’ and connects the end section and the latch section to each other. The end section 26’ has a through section D for engaging with the locking element 50.

[0073] The locking device 10 may optionally have an introduction or centering aid 90. The introduction or centering aid 90 may be disposed and / or secured in the drive lever channel 218 of the door device 200 (see [link]). Figure 9b ).

[0074] As previously described, a coupling device 25 for coupling the drive latch 27 is fastened at the drive rod 22. The coupling device 25 has a receiving portion 30 into which the drive latch 27 can be introduced via its end portion 27'. The coupling device 25 and the drive latch 27 are configured such that when the end portion 27' is introduced into the receiving portion 30, the drive latch 27 is coupled to the coupling device 25 by locking.

[0075] The coupling device 25 is configured such that the coupling of the drive bolt 27 at the coupling device 25 can be reversibly disengaged. Therefore, the operating element 80 can be coupled to the locking element 50, and the locking element 50 can be moved to the released position. Thus, the previously coupled drive bolt 27 can be decoupled from and removed from the coupling device 25.

[0076] Figure 8 A longitudinal section of a portion of the first door leaf 204 is shown. A recess 212 for the drive mechanism 14 is formed in the door leaf 204. Furthermore, a recess 214 for the lock housing 12 is formed in the door leaf 204. Two additional recesses 216 for the coupling device 30 are also formed in the door leaf 204. Additionally, two concealed (“inwardly offset in the door leaf 204”) latch channels 218 for driving the latches 26 and 27 are formed in the door leaf 204. The latch channels 218 extend from one of the recesses 216 and respectively enter the upper side 204' or lower side 204” of the door leaf 204. An insertion and centering aid 90 can optionally be inserted into the latch channel 218 in the end region adjacent to the additional recess 216 (see [reference]). Figure 9bThe guide or centering aid has a through portion (without reference numerals) for driving the latches 26, 27. In the example, the through portion of the guide or centering aid 90 widens from the cross-section of the driving latch in the opposite direction to the guide direction, as described above.

[0077] exist Figures 9a to 9c The diagram illustrates a method for installing the locking device 10 at the door device 200.

[0078] First, at least one door assembly 200 is provided, the door assembly having a frame 202 and at least one door leaf 204, the door leaf having a recess or a clearance, as in combination. Figure 8 As described.

[0079] Prior to, simultaneously with or subsequently provided locking device 10 (see Figure 9a After the locking device is provided, it is positioned at the door leaf 204. To do this, the drive unit 14 is inserted into the recess 212, the coupling unit 25 is inserted into the other recess 216, and the lock housing 12 is inserted into the recess 214. Thus, the locking device 10 is positioned at the door leaf 204 in the inserted position.

[0080] Accordingly, the lock housing 12 is at least partially or completely screwed onto the door leaf 204. Thus, the lock housing 12 and the components of the locking device 10 fastened thereto are secured to the door leaf 204 (see [link]). Figure 9b ).

[0081] Previously, drive bolts 26 and 27 were provided simultaneously or subsequently. After the drive bolts were provided, drive bolts 26 and 27 were pushed into the bolt channels 218 formed at the door leaf 204 (see...). Figure 9b ).

[0082] During the further insertion process, the end sections of the drive latches 26 and 27 are introduced into the coupling device 25. Here, when the corresponding end sections are introduced into the corresponding receiving portions 30 of the coupling device 25, the drive latches 26 and 27 are coupled to the coupling device 25 by locking.

[0083] Once one or both of the drive bolts 26 and 27 are removed again, the operating element 80 can be screwed into the threaded section 60 of the locking element 50, which is in the form of an internal thread 62, via a through portion 12' in the lock housing 12 and a through portion 22' in the drive rod 22. If the bolt 82 is then pulled outward away from the lock housing 12, the locking element 50 is displaced from the coupled position toward the released position. Thus, the drive bolts 26 and 27 can be pulled out of the bolt channels 218 without disassembling the locking device 10 or removing it entirely from the door leaf 204.
