Description

[0001] Title: Latch arrangement and sash arrangement

[0002] Description

[0003] The invention relates to a locking arrangement with the features of the preamble of claim 1 and a wing arrangement with the features of the independent claim.

[0004] Locking assemblies are known from the prior art and are frequently used in conjunction with a connecting rod in a sash assembly. Known sash assemblies typically comprise a frame defining an opening and a sash pivotally mounted on the frame. The sash closes the opening in a closed position and releases the opening in an open position. A locking assembly is often arranged on the sash to lock the sash to the frame in the closed position. Locking prevents unintentional opening of the sash, i.e., unintentional movement of the sash from the closed position to the open position.

[0005] In order to operate the locking arrangement and thus lock or release the sash to the frame, an operating device which is operated by a user can be provided on the sash. The operating device can comprise a handle such as a doorknob. Often a distance must be bridged between the locking arrangement and the operating device, in particular when the locking arrangement is arranged at the top or bottom of the sash and the operating device is arranged in the middle of the sash. For this purpose, connecting rods are typically used which overcome the distance and actuate the locking arrangement depending on actuation of the operating device.

[0006] It is an object of the present invention to provide a locking arrangement that has improved properties, in particular, that facilitates assembly. Furthermore, it is an object of the present invention to provide a wing assembly that has such a locking arrangement.

[0007] The invention solves these problems by the features of the

[0008] Claim 1 and claim 15 . Advantageous embodiments and further developments of the invention emerge from the dependent claims .

[0009] A locking arrangement according to the invention is designed and / or intended for a sash arrangement comprising a sash and a frame for locking the sash to the frame. The locking arrangement has a guide device and a locking module. The locking module comprises a locking section for locking the sash to the frame and a connecting section for connecting the locking module to a drive rod. In a use mode, the locking module can be moved between a locked position and an unlocked position. The guide device is designed to guide the locking module during a displacement between the locked position and the unlocked position. The locking module can also be moved into a transport position to provide a transport mode. The guide device has a securing section for securing the locking module in the transport position.

[0010] The transport mode advantageously allows the locking module to be mounted on the sash together with the guide device, in particular at the same time. This eliminates the need to join the locking module and guide device when mounting the locking arrangement on the sash, which is why the locking arrangement facilitates assembly. In addition, the transport mode provides a loss protection. As a result of the locking module being secured, the locking module cannot be moved relative to the guide device in the transport position, or can only be moved within narrow limits, in particular until a force threshold value (transfer force threshold value) is exceeded.

[0011] The locking module is designed to be transferable between the transport mode and the use mode. Transferring the locking module between the transport mode and the use mode may require a force (exceeding the transfer force threshold). The force required to transfer the locking module between the transport mode and the use mode may differ from the force required to move it between the locked position and the unlocked position, particularly in terms of its magnitude and / or direction.

[0012] The locking module can have the use mode when the locking module is arranged on the sash, in particular when the locking module is fastened to the sash and / or inserted into the sash. The locking module can have the transport mode when the locking module is not arranged on the sash, in particular when the locking module is not fastened to the sash and / or not inserted into the sash. The locking module can be transferred from the transport mode to the use mode when the locking module is arranged or fastened on the sash and / or when the locking module is inserted into the sash. The transport position can be different from the locked position and the unlocked position. The locking module can have the transport position for transport to a sash for the purpose of mounting the locking arrangement on the sash.

[0013] The securing section can prevent an unintentional departure from the transport position, in particular during transport of the locking arrangement.

[0014] In the locked position, the locking section can engage in a recess in the frame, thereby locking the sash to the frame in the closed position. In the unlocked position, the locking section cannot engage in the recess in the frame, thereby releasing the sash.

[0015] The locking module extends along a longitudinal axis. The locking portion can be arranged at one end of the locking module. The connecting portion can be arranged at an end of the locking module opposite the locking portion (along the longitudinal axis).

[0016] The guide device can also be referred to as a locking guide; in particular, the guide device can be a locking guide. The guide device can mount the locking module for longitudinal displacement. In other words: The guide device can mount the locking module such that the locking module is displaceable parallel to a longitudinal axis of the locking module (the locking module can be displaced along or parallel to its longitudinal axis relative to the guide device).

[0017] The guide device is designed so that the locking module slides along or in the guide device when moving between the locked position and the unlocked position.

[0018] The guide device can contact the locking module directly or immediately. A lubrication system can be arranged between the guide device and the locking module. The lubrication can separate a contact surface of the guide device from a contact surface of the locking module. By separating the contact surfaces from one another using lubrication, direct or immediate contact between the guide device and the locking module can be prevented.

[0019] The guide device can comprise a main body extending parallel to the longitudinal axis of the locking module. The guide device can encompass the locking module, in particular outwardly, e.g., radially. The guide device can be circumferentially closed. The guide device can be sleeve-shaped.

[0020] The guide device can have a number, in particular 1,

[0021] 2, 3 or 4, of fastening sections for fastening the locking arrangement to the wing. The fastening sections can extend laterally, in particular away from the main body. The fastening sections can extend in a direction perpendicular to the longitudinal axis of the locking module or in a direction perpendicular to a longitudinal axis of the guide device.

[0022] The guide device can be constructed in one piece. The locking module can be constructed in one piece.

[0023] The locking module can be accommodated by the guide device. The locking module can be held by the guide device.

[0024] The guide device and the locking module can be made of different materials. Preferably, the guide device and the locking module can comprise a low-friction material pairing. The low-friction material pairing can have a coefficient of sliding friction of less than 0.1, in particular 0.05.

[0025] The locking module can be made of steel.

[0026] The drive rod may have a coupling element that can be reversibly or releasably coupled to a corresponding drive rod coupling element of an actuating device. The coupling element may be arranged at one end of the drive rod. At an end of the drive rod opposite the coupling element, the drive rod may be designed to be connectable to the locking module.

[0027] A course of a longitudinal axis of the locking arrangement, a course of a longitudinal axis of the locking module, a course of a longitudinal axis of the guide device and / or a course of a longitudinal axis of the drive rod can be the same.

[0028] In a further development of the locking arrangement, the securing section can have a holding element for holding, in particular for securing, the locking module in the transport position. In transport mode, in particular in the transport position, the locking module is held, in particular secured, by the holding element. In use mode, in particular outside the transport position, the locking module is not held, in particular secured, by the holding element. For example, the locking module can not be held by the holding element in the locked position or in the unlocked position. The holding element can also be referred to as a securing element. The locking module in transport mode can be held by the holding element by means of static friction.The holding element can be designed to secure a drive rod connected to the locking module in use mode against accidental release of the connection between the drive rod and the locking module, in particular by the holding element blocking decoupling of the drive rod and the locking module. In a further development of the locking arrangement, the locking module can have a receiving section corresponding to the holding element. In the transport position, the holding element interacts with the receiving section such that the locking module is held, in particular by means of the holding element. In the transport position, the holding element can contact the receiving section, in particular directly or immediately.

[0029] In a further development of the locking arrangement, the receiving section (along the longitudinal axis of the locking module) can be arranged between the locking section and the connecting section.

[0030] In a further development of the locking arrangement, the holding element can have a spring part and a nose arranged on the spring part. The receiving section has a recess. In transport mode, the nose engages in the recess. In use mode, the nose does not engage in the recess. The nose can also be referred to as a projection. The spring part can be a spiral spring, in particular a straight or elongated spiral spring. The spring part can have a rectangular cross-section. When transferring or displacing the locking module between the use mode and the transport mode, the spring part can be pre-tensioned. By pre-tensioning the spring part, a force required to transfer the locking module between the use mode and the transport mode (transfer force threshold) can be greater than a force required to displace the locking module between the locked position and the unlocked position.

[0031] In a further development of the locking arrangement, the recess can be delimited by a wall. The nose has an introduction bevel and an exit bevel. The introduction bevel is designed to slide over the wall when the locking module is transferred from the use mode to the transport mode, in particular under pretension of the spring part. The exit bevel is designed to slide over the wall when the locking module is transferred from the transport mode to the use mode, in particular under pretension of the spring part.

[0032] In a further development of the locking arrangement, an angle of the introduction bevel and an angle of the execution bevel can differ in amount. The angle of the introduction bevel is formed between the introduction bevel and a longitudinal axis of the locking arrangement and / or a longitudinal axis of the locking module and / or a longitudinal axis of the guide device. The angle of the execution bevel is formed between the execution bevel and a longitudinal axis of the locking arrangement and / or a longitudinal axis of the locking module and / or a longitudinal axis of the guide device.

[0033] A force required to transfer the locking module from the use mode to the transport mode may differ from a force required to transfer the locking module from the transport mode to the use mode, in particular in its amount and / or direction. The amount of force required to transfer the locking module from the use mode to the transport mode may depend on the angle of the insertion bevel. The amount of force required to transfer the locking module from the transport mode to the use mode may depend on the angle of the execution bevel.

[0034] In a further development of the locking arrangement, the angle of the insertion bevel can be 15° to 75°, in particular 15° to 60°, 20° to 40°, or 30°. Additionally or alternatively, the angle of the exit bevel can be 15° to 75°, in particular 30° to 60°, 35° to 55°, or 45°.

[0035] In a further development of the locking arrangement, the locking module can have a first connecting element within the connecting section for connecting the locking module to a second connecting element of a drive rod. The locking module can be connected to the drive rod when the first connecting element is connected to the second connecting element. The first connecting element can have a thread and the second connecting element can have a thread corresponding to the first connecting element. For example, the first connecting element can have an internal thread and the second connecting element can be an external thread. The locking module can be connected to the drive rod by means of a screw connection. In a further development of the locking arrangement, the first connecting element can have a first toothing, in particular an internal toothing.The second connecting element can have a second toothing corresponding to the first toothing, in particular an external toothing. The first toothing and / or the second toothing can extend parallel to a longitudinal axis of the locking arrangement. The locking module can be connected to the drive rod when the second toothing is inserted into the first toothing. The second toothing can be inserted into the first toothing or removed from the first toothing in a direction perpendicular to the longitudinal axis of the locking arrangement.

[0036] The first toothing and the second toothing can be inserted into one another in several different positions. The several different positions can differ by the number of teeth of the first and second toothing that are in engagement. Alternatively or additionally, the several different positions can differ by a different size of axial overlap between the first toothing and the second toothing. This facilitates a length adjustment of the locking arrangement.

[0037] A projecting length of a drive rod connected to the locking module can be adjustable by means of the first toothing and the second toothing. The projecting length can be adapted to a distance between the locking arrangement and a receptacle of the wing, wherein the receptacle is designed to receive an actuating device. The projecting length can extend from one end of the locking module to one end of the drive rod.

[0038] The several different positions can differ by different protruding lengths.

[0039] In a further development of the locking arrangement, the guide device can be configured and / or intended to secure a connection between the locking module and the drive rod against unintentional release in transport mode, in particular in the transport position, and / or in use mode. Advantageously, the locking arrangement can be mounted on the sash together with a drive rod connected to the locking module, in particular simultaneously, without the risk of unintentional release of the drive rod from the locking module.

[0040] In a further development of the locking arrangement, the guide device encompasses, in particular covers, the connecting section in transport mode, in particular in the transport position, and / or in use mode, such that a connection between the locking module and the drive rod is secured against unintentional release. For example, the guide device can encompass the connecting section in transport mode, in particular in the transport position, and / or in use mode, such that the second toothing inserted into the first toothing cannot be removed from the first toothing.

[0041] In a further development of the locking arrangement, the locking module can have a locking bevel within the locking section. The locking bevel is designed to slide along an inner wall of a recess in the sash arrangement, in particular one corresponding to the locking module, when the sash is locked, until the locked position is reached. The locking bevel can be designed to transfer the sash into the closed position by sliding along the inner wall. The frame can have the recess.

[0042] In a further development of the locking arrangement, the guide device can be formed from a plastic, in particular from copolymeric polyoxymethylene or polyamide 6. The plastic can be insensitive to moisture.

[0043] A sash assembly according to the invention comprises a frame, a sash, and a previously described locking assembly. The sash is held by the frame and can be displaced, in particular pivoted, relative to the frame between an open position and a closed position. The locking assembly is mounted on or in the sash and locks the sash to the frame when the sash is in the closed position and the locking module is in the locked position. The locking assembly does not lock the sash to the frame when the locking module is in the unlocked position.

[0044] Further advantages and aspects of the invention emerge from the claims and from the following description of preferred embodiments of the invention, which are explained with reference to the figures. Identical and functionally identical elements are provided with identical reference numerals, if necessary, however, only once. They show:

[0049] Fig. 5 is a schematic oblique view of the locking arrangement of Fig. 4, wherein the guide device is not shown in section, Fig. 6 is a further schematic oblique view of the locking arrangement of Fig. 5, viewed from a side opposite to Fig. 5,

[0050] Fig. 7 is a schematic view of a wing arrangement with a frame, a first wing and a second wing, and

[0051] Fig. 8 is a schematic sectional view of the first wing of Fig. 7 and the locking arrangement of Fig. 1.

[0052] Fig. 1 to 3 show a locking arrangement 10. The locking arrangement 10 is designed for a sash assembly comprising a sash and a frame for locking the sash to the frame.

[0053] The frame defines an opening, and the sash is pivotally mounted on the frame. The sash closes the opening in a closed position and releases the opening in an open position. If the locking arrangement 10 is arranged on the sash, the locking arrangement 10 can lock the sash to the frame in the closed position and release it in the open position.

[0054] The locking arrangement 10 has a guide device 12 and a locking module 14. The guide device 12 is designed as a separate component from the locking module 14. The guide device 12 is formed as a single piece. In the example, the guide device 12 is made of copolymer polyoxymethylene.

[0055] The guide device 12 has a main body extending along or parallel to a longitudinal axis 16 of the locking module 14. The guide device 12 is sleeve-like and surrounds the locking module 14 on the outside. As a result, the locking module 14 is held by the guide device 12. The guide device 12 supports the locking module 14 for longitudinal displacement, so that the locking module 14 can be displaced along or parallel to the longitudinal axis 16 of the locking module 14.

[0056] In the example, the locking module 14 is made of steel. The locking module 14 is constructed in one piece.

[0057] The locking module 14 is displaceable between a locked position and an unlocked position in a use mode. The use mode is shown in Fig. 2 and 3, wherein the unlocked position of the locking module 14 is shown in Fig. 2 and the locked position of the locking module 14 is shown in Fig. 3. The guide device 12 is designed to guide the locking module 14 during displacement between the locked position and the unlocked position. In other words, when the locking module 14 is displaced between the locked position and the unlocked position, the locking module 14 slides along the guide device 12 (the locking module 14 is displaced relative to the guide device 12 along the longitudinal axis 16).

[0058] The locking module 14 comprises a locking section 18 for locking the sash to the frame. The locking section 18 is arranged at one end of the locking module 14. In the example, the locking section 18 extends from the end of the locking module 14 to a center of the locking module 14. In alternative embodiments, the locking section can be larger or smaller.

[0059] When the locking arrangement 10 is arranged on the sash, the sash is in the closed position and the locking module 14 is in the locked position, the locking section 18 engages in a recess of the frame. As a result, the sash is locked to the frame. In the unlocked position, the locking section 18 does not engage in the recess of the frame. As a result, the sash is released.

[0060] A locking bevel 20 is arranged within the locking section 18 (see also Fig. 4). In alternative embodiments, the locking section can be defined in its extension by the locking bevel. The locking bevel 20 is designed to slide along an inner wall of a recess in the frame when the sash is locked until the locked position is reached. By sliding along the locking bevel 20 on the inner wall, the sash can be transferred into the closed position if the sash is not yet completely in the closed position.

[0061] The locking module 14 can also be moved into a transport position to provide a transport mode. The transport mode and the transport position of the locking module 14 are shown in Fig. 1.

[0062] In the transport position, the locking section 18 in the example is arranged completely within the guide device 12.

[0063] The locking module 14 can be transferred or relocated between the transport mode and the use mode. The transport position differs from the locked position and the unlocked position.

[0064] The guide device 12 has a securing section 22 for securing the locking module 14 in the transport position. The securing section 22 prevents unintentional departure from the transport position, in particular during transport of the locking arrangement 10. The securing section 22 is arranged at one end of the guide device 12. In the example, the securing section 22 extends over a length which corresponds to 40% of a total length of the guide device 12. A holding element 24 is arranged within the securing section 22, see Fig. 1. In alternative embodiments, the securing section can be defined in its extension by the holding element. The holding element 24 is designed to hold the locking module 14 in the transport position, in particular to secure it. In use mode, the locking module 14 is not held by the holding element 24.

[0065] In the illustrated embodiment, the holding element 24 comprises a spring part 26 and a nose 28 arranged on the spring part 26. The spring part 26 is formed by a U-shaped opening 30 in the guide device 12 (see also Fig. 5).

[0066] The locking module 14 has a receiving section 32 corresponding to the holding element 24. The receiving section 32 is arranged on the locking section 18, in particular, the receiving section 32 adjoins the locking section 18. The receiving section 32 extends over a length which, in the example, corresponds to 20% of a total length of the locking module 14.

[0067] The receiving section has a recess 34. In transport mode, the nose 28 engages in the recess 34, see Fig. 1. In use mode, the nose 28 does not engage in the recess 34, see Figs. 2 and 3. In other words: in transport mode, the locking module 14 is held on the guide device 12 by means of the holding element 24 and in use mode, the locking module 14 is not held by the holding element 24.

[0068] The recess 34 is defined by a wall 36. The nose 28 is designed to slide over the wall 36 when transferring the locking module 14 from the use mode to the transport mode.

[0069] The nose 28 has an introduction bevel 38 and an execution bevel 40, see Fig. 1. An angle 42 of the introduction bevel 38 and an angle 44 of the execution bevel 40 differ from each other in amount.

[0070] In the illustrated embodiment, the angle 42 of the insertion bevel 38 is formed between the insertion bevel 38 and the longitudinal axis 16 of the locking module 14, see Fig. 2. The angle 44 of the execution bevel 40 is formed between the execution bevel 40 and the longitudinal axis 16 of the locking module 14, see Fig. 3.

[0071] The course of the longitudinal axis of the locking module 14, the course of a longitudinal axis of the locking arrangement 10, and the course of a longitudinal axis of the guide device 12 are identical. Therefore, only the longitudinal axis 16 of the locking module 14 is shown in the figures.

[0072] In the illustrated embodiment, the angle 42 of the insertion bevel 38 is 30°. The angle 44 of the execution bevel 40 is 45°. When the locking module 14 is transferred from the use mode to the transport mode, the insertion bevel 38 slides over the wall 36, thereby pre-tensioning the spring part 26. Subsequently, the execution bevel 40 slides over the wall 36, releasing the pre-tension of the spring part 26. By releasing the pre-tension of the spring part 26, the nose 28 engages in the recess 34.

[0073] When transferring the locking module 14 from the transport mode to the use mode, the lead-out bevel 40 slides over the wall 36, thereby pre-tensioning the spring part 26. Subsequently, the nose 28 no longer engages in the recess 34, and the lead-in bevel 38 slides over the wall 36, releasing the pre-tension of the spring part 26.

[0074] Due to the different angles 42, 44 of the introduction bevel 38 and the execution bevel 40, a force required for transferring from the use mode to the transport mode differs in magnitude from a force required for transferring from the transport mode to the use mode.

[0075] The locking module 14 comprises a connecting section 46 for connecting the locking module 14 to a drive rod 48, see Figs. 1 to 3. The drive rod 48 is designed to transfer the locking module 14 between the locked position and the unlocked position, in particular by displacing the drive rod 48 along or parallel to the longitudinal axis 16 of the locking module 14.

[0076] The connecting section 46 is arranged at an end of the locking module 14 opposite the locking section 18 (along the longitudinal axis 16). The connecting section 46 is arranged on the receiving section 32; in particular, the connecting section 46 adjoins the receiving section 32. In the example, the connecting section 46 extends over a length corresponding to 30% of a total length of the locking module 14. As a result, the receiving section 32 is arranged between the locking section 18 and the connecting section 46.

[0077] The locking module 14 has a recess 50 with two opposite walls 52 within the connecting section 46, see Fig. 4. The two opposite walls 52 each have an internal toothing 54 for connecting the locking module 14 to an external toothing 56 of the drive rod 48 corresponding to the internal toothing 54.

[0078] The internal toothing 54 extends parallel to the longitudinal axis 16 of the locking module 14.

[0079] In the illustrated embodiment, the external toothing 56 of the drive rod 48 is inserted into the internal toothing 54 of the locking module 14. This connects the locking module 14 to the drive rod 48. The insertion of the external toothing 56 into the internal toothing 54 or the removal of the external toothing 56 from the internal toothing 54 occurs in a direction perpendicular to the longitudinal axis 16 of the locking module 14.

[0080] In Fig. 1 to 3, the drive rod 48 is connected to the locking module 14 in such a way that all teeth of the internal toothing 54 engage with the external toothing 56.

[0081] In an alternative design, the drive rod can be connected to the locking module in such a way that not all of the teeth of the internal toothing engage with the external toothing. In other words, the internal toothing and the external toothing can be inserted into one another in several different positions, with the different positions differing by the number of teeth in engagement. For example, 3, 5, 8, or 15 teeth of the internal toothing on one of the two walls can be in engagement with the external toothing.

[0082] By means of the engaged teeth, a projecting length 58 of the drive rod 48 connected to the locking module 14 can be adjusted, see Fig. 1 or 4. The projecting length 58 extends from the end 60 of the locking module 14 having the connecting section 46 to one end of the drive rod 48.

[0083] The guide device 12 is designed to

[0084] Connection between the locking module 14 and the drive rod

[0085] 48 in transport mode to prevent it from being accidentally released. The guide device 12 covers the connecting section 46 in the transport position in such a way that the external toothing 56 of the drive rod 48 cannot be removed from the internal toothing 54 of the locking module 14. In the transport position, a distance 62 in the connecting section 46 between the locking module 14 and a wall 64 of the guide device 12 opposite the internal toothing 54 is smaller than a thickness 66 of the drive rod 48, see Fig. 1 or 2. The distance 62 can be measured in a direction perpendicular to the longitudinal axis 16 of the locking module 14.

[0086] In use mode, the drive rod 48 is secured by means of the retaining element 24 on the connecting section 46 to prevent it from accidentally leaving the connecting section 46, see Figs. 2 and 3. The nose 28 can be designed to contact the drive rod 48 in use mode. The spring part 26 can then pretension the nose 28 against the drive rod 48. As a result, the drive rod 48 is pressed against the locking module 14 in the insertion direction by means of the spring part 26 and the nose 28.

[0087] Fig. 5 and 6 show the locking arrangement 10 viewed from different sides.

[0088] The guide device 12 has a plurality of openings 68. In Figs. 5 and 6 it is shown that the guide device 12 has a total of three openings 68. One of the openings 68 is arranged on a side of the guide device 12 on which the holding element 24 is arranged. The remaining openings 68 are arranged on a side of the guide device 12 opposite the holding element 24. The locking module 14 can be viewed through the openings 68.

[0089] The locking module 14 can have an inscription 70, see Fig. 6. In the example, the inscription 70 is legible through one of the openings 68. The inscription 70 can be a type designation of the locking module 14.

[0090] The guide device 12 has a number of fastening sections 72 for fastening the locking arrangement 10 to a wing. In total, the guide device 12 has two fastening sections 72, see Figs. 5 and 6. The fastening sections 72 extend laterally in a direction perpendicular to the longitudinal axis 16 of the locking module 14.

[0091] Each fastening section 72 has a through-hole 74. The locking assembly 10 can be fastened to a wing of a wing assembly by means of the through-hole 74. For example, a screw connection can be established between the locking assembly 10 and the wing, with a screw of the screw connection being arranged in each through-hole 74.

[0092] Fig. 7 shows a wing arrangement 100 with a frame 102, a first wing 104 and a second wing 106. For reasons of clarity, the first wing 104 is only partially shown on the right in Fig. 7. The frame 102 delimits an opening 108. The first wing 104 and the second wing 106 are each pivotally mounted on the frame 102. In a closed position of the first wing 104 and the second wing 106, the opening 108 is closed and in an open position of the first wing 104 and the second wing 106, the opening 108 is released. The closed position of the second wing 106 is shown in Fig. 7.

[0093] Fig. 8 shows a section of the first wing 104. The first wing 104 has a drive rod channel 110. The drive rod channel 110 is a circumferentially closed channel within the first wing 104. The drive rod channel 110 can also be referred to as a concealed channel. The drive rod channel 110 extends from a receptacle 112 for an actuating device 114 to a receptacle 116 for a locking assembly 10.

[0094] An actuating device 114 is already inserted into the receptacle 112 for the actuating device 114. The actuating device 114 can be actuated by a user by pressing a handle, for example, a door handle (not shown).

[0095] The locking assembly 10, which is still to be inserted into the receptacle 116, is shown on the right in Fig. 8. The locking assembly 10 is in transport mode. The locking assembly 10, which is to be inserted into the receptacle 116, is connected to a drive rod 48, which is to be inserted into the drive rod channel 110. The insertion of the locking assembly 10 into the receptacle 116 and the insertion of the drive rod device 10 into the drive rod channel 110 occur simultaneously.

[0096] In order to couple the drive rod 48 to be used with the actuating device 114, the actuating device 114 has a drive rod coupling element 120 which can be reversibly or detachably coupled to a corresponding coupling element 76 of the drive rod 48.

[0097] The coupling element 76 is arranged at an end of the drive rod 48 opposite the locking arrangement 10. The coupling element 76 is designed as an elongated hole. The drive rod coupling element 120 of the actuating device 114 has a latch that engages in the elongated hole when coupled. The coupling of the drive rod 48 to the actuating device 114 occurs simultaneously when the drive rod 48 is inserted into the drive rod channel 110 and the locking arrangement 10 is inserted into the receptacle 116.

[0098] In the exemplary embodiment shown, the drive rod 48 has a plurality of coupling elements 76. A total of three elongated holes are provided, with the drive rod coupling element 120 being coupled to one of the three elongated holes. Depending on the length of the drive rod channel 110, the drive rod coupling element 120 is coupled to one of the coupling elements 76. When the locking arrangement 10 is inserted into the receptacle 116 and the drive rod 48 is inserted into the drive rod channel 110, a distance between the actuating device 114 arranged in a center of the first wing 104 and the locking arrangement 10 arranged in an upper wing region is bridged by means of the drive rod 48. As a result, depending on an actuation of the actuating device 114, the locking arrangement 10 can be transferred between the locked position and the unlocked position.

[0099] In order to fasten the locking arrangement 10 inserted into the receptacle 116 to the first wing 104, the projecting length 58 was adjusted before insertion to a distance between the locking arrangement and a receptacle of the wing arrangement such that the fastening sections 72 are flush with the wing.

[0100] After inserting the locking arrangement 10 into the receptacle 116, it is fastened by means of screws which are inserted into the through holes 74.

[0101] If the locking module 14 is in the transport position before the locking arrangement 10 is inserted into the receptacle 116, the locking module can be moved from the transport position into the unlocked position by tightening the screws inserted into the through-holes 74. If the locking arrangement 10 is mounted on the sash 104, the locking module 14 is slidably guided in the guide device 12, specifically along or parallel to the longitudinal axis 16 and thus also along or parallel to the central longitudinal axis of the drive rod channel 110. The locking module 14 is thus slidably guided parallel to an end face of the sash 104 (movement of the locking module 14 parallel to the sash end face).

[0102] Two centering elements 78 are arranged on the drive rod 48 for centering the drive rod 48 within the drive rod channel 110. The two centering elements 78 and the drive rod 48 are designed as separate components. The centering elements 78 are fixed to the drive rod 48. The two centering elements 78 are made of the same material as the guide device 12.

[0103] Fig. 8 shows that the previously described locking arrangement 10 and driving rod 48 is to be inserted into the upper half of the first wing 104. The first wing 104 has in its lower half a further driving rod channel 124 and a further receptacle 126. A further locking arrangement (not shown) and a further driving rod (not shown) can be inserted into the further driving rod channel 124 and into the further receptacle 126. The further locking arrangement and the further driving rod can have the same or functionally identical features as the previously described locking arrangement 10 and driving rod 48. By means of the two locking assemblies and the two driving rods, the first wing 104 can be locked or released in the closed position on actuation of the actuating device 114 in its lower half and simultaneously in its upper half on the frame 102.

[0104] As explained with reference to the figures, the invention provides a locking arrangement which facilitates assembly.
