[0002] Locking device and wing arrangement

[0003] Description

[0004] The invention relates to a drive rod device for actuating a locking device, a locking device and a wing arrangement.

[0005] Espagnolette devices are known from the prior art and are frequently used in conjunction with a locking device in a sash arrangement, which as a whole is sometimes referred to as a multi-point locking device. Known sash assemblies typically comprise a frame which defines an opening and a sash which is pivotally mounted on the frame. The sash closes the opening in a closed position and releases the opening in an open position. A locking device is frequently provided on the sash to lock the sash to the frame in the closed position. The locking prevents the sash from being accidentally moved from the closed position to the open position.

[0006] In order to actuate the locking device and thus lock or release the sash to the frame, an actuating device which is actuated by a user can be provided on the sash. The actuating device can comprise a handle (e.g. a door handle). A distance often has to be overcome between the locking device and the actuating device, in particular when the locking device is arranged on an upper or lower sash region and the actuating device is arranged in the middle of the sash. For this purpose, drive rod devices are typically used which bridge the distance and actuate the locking device depending on actuation of the actuating device.

[0007] A drive rod device is inserted into a drive rod channel of the sash, particularly if a concealed arrangement is desired. The drive rod channel can be designed as a circumferentially closed channel within the sash. The drive rod channel often extends from a receptacle for the operating device to a receptacle for the locking device. In order to enable insertion of the drive rod device into the drive rod channel, the cross section of the drive rod channel is usually larger than the cross section of the drive rod device. This advantageously makes it particularly easy to move a drive rod device inserted in the drive rod channel in a longitudinal direction of the drive rod channel.

[0008] In order to couple the drive rod device inserted into the drive rod channel to the actuating device, the actuating device can have a drive rod coupling element that can be reversibly or detachably coupled to a corresponding coupling element of the drive rod device. The coupling element is usually arranged at one end of the drive rod device. At an end of the drive rod device opposite the coupling element, the drive rod device can be designed so that it can be coupled to the locking device. The locking device can have a pin, a bolt or a latch device. Alternatively, an element of the drive rod device and the locking device can be designed as a single piece.For example, the drive rod device can comprise a drive rod with a pin arranged at the end opposite the coupling element, the pin and drive rod being designed as a single piece. By actuating the locking device by means of the drive rod device, the locking device can be displaced such that the locking device engages in a recess on or in the frame and thereby locks the sash to the frame in the closed position, or such that the locking device does not engage in the recess in the frame and thereby releases the sash.

[0009] It is an object of the present invention to provide a drive rod device having improved properties, in particular, which facilitates assembly and is more reliable in operation. Furthermore, it is an object of the present invention to provide a locking device and a leaf assembly, each comprising such a drive rod device.

[0010] The invention solves these problems with the features of claim 1, claim 14 and claim 15. Advantageous embodiments and further developments of the invention emerge from the dependent claims.

[0011] A drive rod device according to the invention is designed and / or intended for actuating a locking device, wherein the drive rod device can be inserted into a drive rod channel of a leaf arrangement. The drive rod device has a drive rod and at least one centering element for centering the drive rod within the drive rod channel, i.e., relative to the walls delimiting the drive rod channel. The centering element can be fixed or is fixed to the drive rod.

[0012] Advantageously, the centering element is designed to position the drive rod within the drive rod channel in such a way that the drive rod is aligned relative to an actuating device, so that no correction of the alignment of the drive rod is required when establishing a coupling between the drive rod and the actuating device. This facilitates the establishment of a coupling between the drive rod and the actuating device. In particular, the coupling can be established simultaneously with the insertion of the drive rod into the drive rod channel. The drive rod device thus facilitates assembly.

[0013] Furthermore, the centering element advantageously provides a local thickening of the drive rod, which limits bending of the drive rod due to axial compressive stress during actuation, preventing or at least significantly reducing buckling of the drive rod. This makes the drive rod device particularly reliable in operation.

[0014] The connecting rod channel can have a rectangular or round cross-section. The centering element can be inserted into the connecting rod channel together with the connecting rod. The centering element can be fixed to the connecting rod before inserting the connecting rod device into the connecting rod channel (the centering element is fixed to the connecting rod before insertion).

[0015] The drive rod extends along a central longitudinal axis. The drive rod can have a rectangular or a round cross-section. In the case of a rectangular cross-section, the drive rod can have two flat sides ("width of the drive rod") and two narrow sides ("thickness of the drive rod"). One, two, three, or four centering elements can be fixable or fixed to the drive rod.

[0016] The drive rod can have a coupling element at one end for coupling to a corresponding drive rod coupling element of an actuating device. At an end of the drive rod opposite the coupling element, the drive rod can be connectable to a locking device. Alternatively, the drive rod and the locking device can be designed as a single piece. In particular, the locking device, for example in the form of a pin, can be arranged on the drive rod at the end opposite the coupling element (bolt side), the locking device and the drive rod being designed as a single piece. The centering element and the drive rod can be designed as separate components. The centering element and the drive rod can be made from the same or different materials. For example, the drive rod can be made from a metal.

[0017] In a further development of the drive rod device, the centering element can be positioned in a positioning position on or along the drive rod and can be fixed to the drive rod in a fixing position (relative to the drive rod) that differs from the positioning position. The centering element can be transferred or displaced between the positioning position and the fixing position. In the positioning position, the centering element can be positioned at any position along the drive rod. After being positioned on the drive rod, the centering element can be transferred into the fixing position. For example, in the positioning position, the centering element can be displaceable, in particular only, along or parallel to a longitudinal axis of the drive rod. In the positioning position and in the fixing position, the centering element can surround the drive rod outwards, for example radially.The centering element can have a passage, wherein in the positioning position the drive rod is inserted into the passage.

[0018] The centering element can be designed such that transfer or displacement of the centering element between the positioning position and the fixing position occurs by rotating or pivoting the centering element about a pivot axis, wherein the pivot axis is oriented orthogonally to the central longitudinal axis of the drive rod. Preferably, the pivot axis can be oriented orthogonally to a flat side of the drive rod.

[0019] In a further development of the drive rod device, the centering element can be fixed to the drive rod by rotating or pivoting about a pivot axis through an angle of 25° to 90°, in particular 30° to 60°, 30° to 40° or 35°. Advantageously, the rotation can take place without additional tools. This means that the centering element can be fixed to the drive rod without additional tools, which simplifies fixing the centering element to the drive rod. The rotation of the centering element can take place relative to the drive rod, for example relative to a flat side of the drive rod. The centering element can be moved from the positioning position into the fixing position by rotating or pivoting relative to the drive rod, in particular through the above-mentioned angle. The centering element can be moved by rotating or pivoting in the opposite direction to the rotation.a contrary pivoting from the fixing position into the positioning position.

[0020] In a further development of the drive rod device, the centering element can be fixable or fixed to the drive rod by means of a positive, non-positive and / or material-locking connection. In the fixing position, the centering element and the drive rod can have a positive, non-positive and / or material-locking connection. The material-locking connection can be a clamping connection. The centering element can be U-shaped and can be fixable to the drive rod by means of a clamping connection, wherein in particular in the fixing position the drive rod is encompassed by the U-shaped centering element. The material-locking connection can be provided on its own or to support another type of connection.

[0021] In a further development of the drive rod device, the centering element can have a first locking element to provide a positive connection. The drive rod can have a second locking element corresponding to, preferably complementary to, the first locking element. The centering element can be or is fixed to the drive rod by means of a locking connection formed by the first locking element and the second locking element.

[0022] In a further development of the drive rod device, the first locking element can have a locking lug and the second locking element can have a locking opening. It is also conceivable for the first locking element to be designed as a locking lug and the second locking element as a locking opening. The locking opening can be a recess, in particular a passage.

[0023] In a further development of the drive rod device, the

[0024] Centering element has at least one (outward-facing) sliding surface. "Outward-facing" means that the sliding surfaces face away from the drive rod when the centering element is mounted on the drive rod. The at least one sliding surface is each designed to slide along a wall of the drive rod channel. The sliding surface can slide along the wall when the drive rod device is inserted into the drive rod channel and when the locking device is actuated. The centering element can have two opposing sliding surfaces, each designed to slide along one of two opposite walls of the drive rod channel.

[0025] In a further development of the connecting rod device, the sliding surface can be flat or convex, in particular uniaxially convex. Advantageously, the convex shape of the sliding surface simplifies the insertion of the connecting rod device into the connecting rod channel. If the centering element has multiple sliding surfaces, at least one of the sliding surfaces can be flat or convex.

[0026] In a further development of the drive rod device, the centering element can be designed point-symmetrically in a longitudinal section. Alternatively, the centering element can be designed point-symmetrically to a center of gravity of the centering element. Advantageously, the

[0027] Point symmetry the production of the centering element.

[0028] Due to the point symmetry, the centering element can be fixed to the drive rod regardless of the preferred direction. This simplifies installation.

[0029] In a further development of the drive rod device, the centering element is made of a plastic, in particular of one of the copolymers polyoxymethylene (POMC) or polyamide 6 (PA6). The plastic can be moisture-resistant.

[0030] In a further development of the drive rod device, the centering element can have a receiving space. The drive rod is arranged within the receiving space when the centering element is fixed to the drive rod. In the fixing position and / or in the positioning position, the drive rod can be arranged within the receiving space.

[0031] In a further development of the drive rod device, the receiving space can have a closed perimeter. The closed perimeter can prevent the drive rod from accidentally or laterally leaving the receiving space, particularly when the centering element is displaced along a longitudinal axis of the drive rod.

[0032] In a further development of the drive rod device, the receiving space can have two opposite openings for arranging the drive rod within the receiving space. Each opening has a first opening section and a second opening section. The drive rod is arranged within the first opening sections for positioning the centering element on the drive rod. The drive rod is arranged within the second opening sections when the centering element is fixed to the drive rod. Each opening can be arranged on an end face of the centering element. Each opening can extend from the end face up to 2 / 3 of a side surface of the centering element. A height of the first

[0033] Opening sections may differ from a height of the second opening sections. A ratio of the height of the second opening sections to the height of the first

[0034] Opening sections can be 0.5 to 0.75, in particular 0.55 to 0.7 or 0.6 to 0.65.

[0035] A locking device according to the invention for a leaf arrangement with a drive rod channel has a previously described drive rod device and a locking device which is coupled or connected to the drive rod device. The drive rod can be coupled or connected to the locking device. In particular, one end of the drive rod can be coupled or connected to the locking device. For example, the locking device can comprise a bolt which is coupled and connected to the end of the drive rod at one bolt end of the bolt. At another end of the drive rod, a coupling element for reversibly or detachably coupling the drive rod to a

[0036] An actuating device may be provided. A sash arrangement according to the invention has a locking device as described above, a frame and a sash with a drive rod channel. The sash is held by the frame and mounted so as to be pivotable relative to the frame. The drive rod device is arranged within the drive rod channel. By actuating the locking device by means of the drive rod device, the locking device can be displaced such that the locking device engages in a recess in the frame and thereby locks the sash to the frame in the closed position, or such that the locking device does not engage in the recess in the frame and thereby releases the sash. The sash can have a number of drive rod channels, in particular 1 or 2 drive rod channels. A previously described drive rod device can be arranged in each of the drive rod channels.

[0037] Further advantages and aspects of the invention emerge from the claims and 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, but only once. They show:

[0050] Fig. 1 shows a wing assembly 100 with a frame 102, a first wing 104, and an optional second wing 106, which may alternatively be a fixed panel (not shown). For clarity, the first wing 104 is only partially shown on the right in Fig. 1.

[0051] The frame 102 defines an opening 108. The first wing 104 and the second wing 106 are each pivotally mounted on the frame 102. When the first wing 104 and the second wing 106 are closed, the opening 108 is closed, and when the first wing 104 and the second wing 106 are open, the opening 108 is exposed. Fig. 1 shows the closed position of the second wing 106. Fig. 2 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. In the example, the drive rod channel 110 has a square cross-section. The cross-section of the drive rod channel 110 can, for example, have the dimensions 15 mm x 15 mm.The drive rod channel 110 extends from a receptacle 112 for an actuating device 114 to a receptacle 116 for a locking device 118.

[0052] 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 (not shown), for example, a door handle.

[0053] The locking device 118, which is still to be inserted into the receptacle 116, is provided to lock the first leaf 104 in the closed position on the frame 102. The locking device 118 is shown on the right in Fig. 2. The locking device 118, which is to be inserted into the receptacle 116, is connected to a drive rod device 10, which is to be inserted into the drive rod channel 110. The insertion of the locking device 118 into the receptacle 116 and the insertion of the drive rod device 10 into the

[0054] In the example, the connecting rod channel 110 occurs simultaneously.

[0055] In order to couple the drive rod device 10, which is to be inserted into the drive rod channel 110, to 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 12 of the drive rod device 10. The coupling element 12 is arranged at an end of the drive rod device 10 opposite the locking device 118. The coupling element 12 is designed as an elongated hole, see also Fig. 9. The drive rod coupling element 120 of the actuating device 114 has a latch which engages in the elongated hole when coupled. The coupling of the drive rod device 10 to the actuating device 114 takes place simultaneously with the insertion of the drive rod device 10 into the drive rod channel 110.

[0056] In the illustrated embodiment, the drive rod device 10 has a plurality of coupling elements 12. 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 12. In alternative embodiments, more or fewer than three elongated holes may be provided.

[0057] When the locking device 118 is inserted into the receptacle 116 and the drive rod device 10 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 device 118 arranged in an upper wing region of the first wing 104 is bridged by means of the drive rod device 10.

[0058] If the drive rod device 10 is coupled to the actuating device 114, the locking device 118 is displaced by means of the drive rod device 10 by actuating the actuating device 114. In particular, the locking device 118 has a bolt which is displaced between a locked position and an unlocked position when the actuating device 114 is actuated by means of the drive rod device 10. When the first wing 104 is closed, the first wing 104 is locked to the frame 102 by moving the bolt into the locked position. The bolt engages in a recess in the frame 102. If the bolt is moved into the unlocked position, the bolt does not engage in the recess and the wing 104 is released. Fig. 2 shows that the previously described drive rod device 10 and locking device 118 are to be inserted into the upper half of the first wing 104.The first wing 104 has, in its lower half, a further drive rod channel 124 and a further receptacle 126. A further drive rod device (not shown) and a further locking device (not shown) can be inserted into the further drive rod channel 124 and into the further receptacle 126. The further drive rod device and the further locking device can have the same or functionally identical features as the previously described drive rod device 10 and locking device 118. By means of the two locking devices and the two drive rod devices, the first wing 104 can be locked or released in the closed position upon actuation of the actuating device 114 in its lower half and simultaneously in its upper half on the frame 102.

[0059] The drive rod device 10 comprises a drive rod 14. In the example, the drive rod 14 has a rectangular cross-section with two flat sides ("width of the drive rod") and two narrow sides ("thickness of the drive rod"). The cross-section of the drive rod 14 is smaller than the cross-section of the drive rod channel 110. The cross-section of the drive rod 14 can, for example, have the dimensions 4 mm x 11 mm. The drive rod 14 is made of a metal, in particular steel. The drive rod device 10 also comprises two centering elements 16 for centering the drive rod 14 within the drive rod channel 110. The two centering elements 16 and the drive rod 14 are designed as separate components.

[0060] The two centering elements 16 are made of a copolymer polyoxymethylene plastic and are fixed to the drive rod 14. The centering elements 16 are fixed to the drive rod 14 before inserting the drive rod 14 into the drive rod channel 110.

[0061] The two centering elements 16 have the same features, which is why one of the two centering elements 16 is described representatively below.

[0062] Fig. 3 to 8 each show one of the two centering elements 16 in different views.

[0063] The centering element 16 can, for example, have a height 18 of 14.5 mm and a width 20 of 14.5 mm, see Fig. 5. The centering element 16 positions the drive rod 14 within the drive rod channel 110 during insertion such that the coupling element 12 is aligned relative to the drive rod coupling element 120, so that no correction of the alignment of the drive rod 14 is required to establish the coupling between the coupling element 12 and the drive rod coupling element 120. As a result, the coupling can take place simultaneously with the insertion of the drive rod 14 into the drive rod channel 110.

[0064] The centering element 16 is fixed by means of a positive connection between the drive rod 14 and the centering element 16. In the example, the positive connection is a snap-in connection. For this purpose, the centering element 16 has a first snap-in element 22 in the form of two snap-in lugs. The drive rod 14 has a second snap-in element 24 in the form of two passages, corresponding to the first snap-in element 22. The two passages can each also be referred to as a snap-in opening. In a locked state, the two snap-in lugs are snapped into the two passages. The centering element 16 is fixed to the drive rod 14 by means of this snap-in connection (see, for example, Fig. 11 or 12).

[0065] When the centering element 16 is fixed to the drive rod 14, the centering element 16 is in a fixing position 26 (see Fig. 2, 11 and 12). When the centering element 16 is not fixed to the drive rod 14, the centering element 16 is in a positioning position 28, see Fig. 9 and 10. In the positioning position 28, the centering element 16 can be moved relative to the drive rod 14 or positioned along the drive rod 14. The centering element 16 can be moved between the fixing position 26 and the positioning position 28 by rotating or pivoting the centering element 16 about a pivot axis, as explained above. The centering element 16 has a receiving space 30 (see Fig. 3). The receiving space 30 is closed along its periphery. The receiving space 30 has two opposite openings 32 for arranging the drive rod 14 within the receiving space 30.In order to arrange the drive rod 14 within the receiving space 30, the drive rod 14 is inserted into both openings 32.

[0066] Each of the two openings 32 has a first opening section 34 and a second opening section 36 (see Fig. 4 in oblique view and Fig. 7 in sectional view). Each second opening section 36 is, in particular only, arranged on one end face of the centering element 16 or borders on this. Each first opening section 34 is arranged on the end face of the centering element 16 and on a side face of the centering element 16 or borders on this. In the positioning position 28, the drive rod 14 is arranged within the first opening sections 34 and in the fixing position 26, the drive rod 14 is arranged within the second opening sections 36.

[0067] A height 38 of the first opening sections 34 differs from a height 40 of the second opening sections 36, see Fig. 4. A ratio of the height 40 of the second opening sections 36 to the height 38 of the first

[0068] The opening section 34 can be, for example, 0.65. The height 40 of the second opening section 36 corresponds to a thickness of the drive rod 14. In the illustrated embodiment, the height 40 of the second opening section 36 is 4 mm.

[0069] The receiving space 30 is delimited by guide surfaces 42, in particular in a corner region of the receiving space 30 (see Figs. 7 and 8). In the illustrated embodiment, the guide surfaces 42 are curved. In the illustrated embodiment, the centering element 16 has four guide surfaces 42, each of which is designed to guide the drive rod 14 when the drive rod is within the first

[0070] Opening sections 34 are arranged. The guide surfaces 42 extend at an angle W1 of, for example, 45° with respect to a longitudinal axis 44 of the centering element 16 (see Fig. 8). In alternative embodiments, the angle may have a different value.

[0071] The centering element 16 has two centering surfaces 46, each arranged on one of the two locking lugs. The centering surfaces 46 extend at an angle W2 of, for example, 30° with respect to the longitudinal axis 44 (see Figs. 7 and 8). In alternative

[0072] Depending on the design, the angle may have a different value.

[0073] The centering surfaces 46 adjoin the guide surfaces 42. In other words: The centering surfaces 46 extend the guide surfaces 42. When the centering element 16 is transferred from the positioning position 28 to the fixing position 26, the drive rod 14 slides along the centering surfaces 46 until the fixing position 26 is reached. The centering surfaces 46 facilitate the transfer from the positioning position 28 to the fixing position 26.

[0074] The centering element 16 comprises two recesses 48, which are each provided on a side wall 50 of the centering element 16, see Fig. 3. Each recess 48 is arranged at one of the two openings 32. The two recesses 48 weaken the side walls 50 such that the side walls 50 act as spring elements when the centering element 16 is transferred from the positioning position 28 into the fixing position 26. In other words: if the centering element 16 is transferred from the positioning position 28 into the fixing position 26, the side walls 50 are deformed until the first locking elements 22 reach the second locking elements 24 and lock into the second locking elements 24 while releasing the preload.

[0075] The centering element 16 has two mutually opposite, uniaxially convex sliding surfaces 52 and two opposite, flat sliding surfaces 54 (see Fig. 5). The sliding surfaces 52, 54 are designed to slide along a wall of the drive rod channel 110. In particular, the uniaxially convex sliding surfaces 52 reduce the contact area between the centering element 16 and the wall of the drive rod channel 110.

[0076] Fig . 9 to 12 show the individual steps for the

[0077] Fixing the centering element 16 to a drive rod 14. Fig. 9 shows the centering element 16, the longitudinal axis 44 of which is rotated relative to the longitudinal axis 56 of the drive rod 14 by an angle W3 of 45° in the example. As a result, the centering element 16 is in the positioning position 28. The centering element 16 is plugged onto the drive rod 14. The plugging takes place by moving the centering element 16 in a plug-in direction 58 which is parallel to the longitudinal axis 56 of the drive rod 14. As a result of the plugging, the drive rod 14 is arranged within the first opening sections 34 and the drive rod 14 is radially surrounded by the centering element 16.

[0078] In the positioning position 28, the centering element 16 is displaced parallel to the longitudinal axis 56 of the drive rod 14 until the centering element 16 reaches the second locking element 24 in the form of two passages. This positions the centering element 16 on the drive rod 14 (see Fig. 10).

[0079] Fig. 10 shows the transfer of the centering element 16 from the positioning position 28 into the fixing position 26. For this purpose, the centering element 16 is rotated about a pivot axis 45 by an angle of 45° relative to the drive rod 14 in a direction of rotation 60. In the example, the pivot axis 45 is oriented orthogonally to a flat side of the drive rod 14 ("width of the drive rod"). During rotation, the first locking element 22 and the second locking element 24 lock together and form a positive connection between the drive rod 14 and the centering element 16. By forming the locking connection, the centering element 16 is fixed to the drive rod 14 and the centering element 16 is in the fixing position 26 (see Figs. 11 and 12).

[0080] No additional tools are required to secure the centering element 16 to the drive rod 14. Therefore, the centering element 16 simplifies the fixation to the drive rod 14.

[0081] As the embodiments shown and explained make clear, the invention provides a drive rod device which facilitates assembly and is more reliable in its operation.
