Description

[0001] The invention relates to a holding device for attaching a partition element, in particular a frameless shower or bathtub partition, to a wall. The holding device comprises a first holding element for attachment to the wall, a second holding element for attachment to the partition element, wherein the two holding elements are rotatably connected to each other about a pivot axis over a limited range of rotation, and at least one locking screw for fixing the two holding elements at a rotation angle within the range of rotation.

[0002] Such a holding device is known from the generic DE 10 2015 002 168 A1.

[0003] Such a mounting device can be used, for example, in a wet room to attach a partition element to a wall, particularly a building wall. The partition element can be a fixed divider or side wall, for instance, for a corner shower or for a bathtub with a shower area installed in a corner of the room. It may be desirable to align the partition element at a 90-degree angle to the wall or parallel to an opposite shower wall. Alignment may also be necessary if the partition element is to be flush with another partition element or if a door is to be hinged to it. Since building walls, within normal dimensional tolerances, are not always at a 90-degree angle to each other or are not perfectly plastered or tiled, it may be necessary to align the partition element within the room when attaching it to the wall.

[0004] A connecting device for a shower enclosure is known from US patent 2006 / 2315342 A1. The connecting device comprises a base plate and a counter plate, between which a shower enclosure is clamped by means of a screw. The connecting device includes an adjusting screw on the base plate, with which the base plate can be adjusted relative to the wall.

[0005] US Patent 2,721,631 A describes an adjustable post structure for a mailbox, street sign, or similar item.

[0006] From EP 0 448 820 B1, a pivot lever is known that is placed on top of the edge of a glazed side wall of a shower. A clamp is attached to the pivot lever and fastened to a building wall with a screw. Another clamp is attached to the free end of the pivot lever to fix the side wall. When both clamps are loosened, an angle between the side wall and the building wall should be adjustable.

[0007] The object of the present invention is to provide a holding device for a flat partition element that is easy to manufacture, allows for easy alignment of the partition element during on-site assembly, and has an aesthetically pleasing design. The object is further to provide a partition arrangement with such a holding device that allows for easier alignment of the partition element during on-site assembly.

[0008] The problem is solved by a holding device of the type mentioned above in that at least one locking screw passes through a respective elongated hole formed in one of the two holding elements and is screwed into a threaded bore formed in the other of the two holding elements.

[0009] The invention is based on the premise that building walls are constructed within dimensional tolerances, so that when attaching the partition element, only small angles in the range of just a few degrees typically need to be compensated for. Usually, the partition element must be readjusted on-site within a rotational angle of less than 5 degrees to achieve the desired 90-degree alignment on a wall, particularly a building wall. The design of the mounting device with an elongated hole allows the partition element to be continuously adjusted within this limited rotational angle range. This rotational angle range is structurally limited by the mounting device. When the at least one locking screw is screwed into the threaded bore, the two mounting elements are clamped against each other at the selected rotational angle, thus preventing any relative movement between the two mounting elements around the axis of rotation or pivot.The holding device is thus designed to securely attach the partition element to the wall. Furthermore, it is advantageous that the holding device is easy to manufacture due to the design according to the invention. Using the holding device, the partition element to be held can be connected in the immediate vicinity of the wall, or flush with the wall, whereby the partition element, when mounted, can expediently be placed on a fixed surface, for example, a floor in a wet room, the edge of a shower or bathtub, or the like.

[0010] Preferably, the screw axis of the at least one locking screw is aligned parallel to the axis of rotation. This allows the holding device to be built particularly compactly. Furthermore, the at least one locking screw is easily accessible and simple to operate with a tool. To further increase the stability of the holding device, two locking screws can be provided. Advantageously, the at least one locking screw has a screw head with a screw head drive, which can be designed as an internal drive. The screw head of the at least one locking screw bears against the holding element in which the elongated hole for the at least one locking screw is formed. Accordingly, the holding element with the elongated hole is arranged or clamped between the screw head of the locking screw and the other holding element, which has the threaded bore for the at least one locking screw.

[0011] The two retaining elements can be designed to rotate relative to each other around the axis of rotation until a first or second stop position is reached, in which at least one locking screw is in contact with one of the two ends of the respective elongated hole. This allows for simple and quick alignment of the separating element to be held within the limited rotational angle range during assembly. The at least one locking screw only needs to be loosened, not completely unscrewed from the threaded bore, when aligning or adjusting the angle of the retaining device. With the locking screw loosened, the two retaining elements can be pivoted relative to each other, whereby the at least one locking screw is displaced relative to the elongated hole during alignment and can abut against the respective end of the elongated hole in both end positions.Thus, by specifying the extension of the respective elongated hole along the arc segment and by specifying the diameter, in particular the screw head diameter of the at least one locking screw, the rotation angle range can be defined and limited.

[0012] Furthermore, each elongated hole can extend along a segment of a circular arc, with the center of this arc segment lying on the axis of rotation. This allows at least one locking screw to remain screwed into the threaded bore during alignment, thus simplifying angular adjustment. To allow relative movement between the two holding elements, at least one locking screw is loosened slightly. Each threaded bore has a bore axis that intersects the circular arc segment at a single point. This bore axis can be aligned parallel to the axis of rotation. Preferably, the holding device has two locking screws, each of which extends through an elongated hole and is screwed into a threaded bore. The bore axes of the threaded bores preferably intersect the respective circular arc segment along which the elongated hole extends.Preferably, the elongated holes with their arc segments extend on a common circle that is arranged concentrically to the axis of rotation.

[0013] Advantageously, the holding device has a defined starting position in which at least one locking screw is preferably located centrally between the two ends of the hole, or equidistant from the two ends of the respective elongated hole. Starting from this defined starting position, the second holding element can thus be adjusted relative to the first holding element in both directions of rotation around the axis of rotation by an angle of 5 degrees each, assuming a rotation angle range of 10 degrees. In the starting position, the rotation angle can therefore be 0 degrees. When the locking screw is loosely inserted into the threaded bore, it abuts the ends of the holes in the end positions when the two holding elements are rotated relative to each other around the axis of rotation, thus limiting the rotation angle range.

[0014] Preferably, the two retaining elements enclose an alignment angle of 90 degrees in their initial position. This is advantageous because, ideally, a plane spanned by the partition element to be held should form a 90-degree angle with a plane spanned by the wall. In this case, the retaining device can be attached to the wall and the partition element without readjustment. If, however, an angle adjustment is necessary, the rotation angle can be changed within the limited range. For example, with a rotation range limited to 10 degrees and a 90-degree initial position, the rotation angle is -5 degrees in the 85-degree position and +5 degrees in the 95-degree position. A particularly compact and sufficiently flexible retaining device can have a rotation angle range of less than 8 degrees, preferably less than 6 degrees.Good results can also be achieved with a rotation angle range limited to at least approximately 4 degrees.

[0015] To further simplify the alignment of the separating element during the installation of the holding device, the device can have a locking element that allows the holding elements to be fixed at a right angle to each other in a starting position. The starting position can be set quickly and reliably using the locking element, without the need for any additional tools, such as a folding ruler or similar equipment, for the installer.

[0016] The locking element can be seated in a retaining bore in one of the two retaining elements and, in the initial position of the two retaining elements relative to each other, can be displaced section by section into a locking bore formed in the other retaining element, with the retaining bore and the locking bore being arranged concentrically to each other in the initial position. When the locking element projects into the locking bore, the retaining device is fixed in the initial position, which can also be described as the locked state. In particular, the locking element can be displaced axially parallel to the axis of rotation, making it easy to operate. The locking element can have a length relative to the axis of rotation that corresponds at most to the depth of the retaining bore. In a released state, the locking element can thus be completely seated in the retaining bore without protruding beyond it. This makes the retaining device particularly compact.In the released state, the second retaining element can be freely rotated about the axis of rotation relative to the first retaining element within the rotational angle range. The locking element can be a locking screw, a locking pin, or the like. Preferably, the locking element is a locking screw, wherein the retaining bore is threaded and the locking bore is unthreaded. The locking bore can be a blind hole. This makes the locking element easy to operate.

[0017] Preferably, the retaining bore is formed in the retaining element in which the respective elongated hole for the at least one locking screw is formed. This allows the locking element and the locking screw to be actuated from the same side of the retaining device. In particular, the retaining bore is formed in the second retaining element and the locking bore in the first retaining element.

[0018] Furthermore, the first and / or the second retaining element can have an elongated shape. In particular, the first retaining element can have a first longitudinal axis or first side surface, and the second retaining element can have a second longitudinal axis or second side surface. The locking element can be arranged between two locking screws, which may be positioned parallel to the second longitudinal axis. The two longitudinal axes intersect at an angle, which can also be referred to as the alignment angle. In the initial position, the alignment angle enclosed by the two longitudinal axes can be 90 degrees, although other initial positions with different angles are also possible.

[0019] The first and second retaining elements can form an L-shape when viewed from above along the axis of rotation. Due to its L-shaped geometry, the retaining device can also be referred to as a stabilizing bracket. The first retaining element can be a short leg of the L, and the second retaining element can be a long leg. This increases the stability of the attachment of the separating element to the second retaining element. The main directions of extension of the legs can define their respective longitudinal axes or leg axes.

[0020] The second retaining element can overlap a section of the first retaining element. In particular, the first retaining element has a support section that is connected to a connecting section of the second retaining element and can rest against it over a flat surface. The support section can widen towards its free end or towards the second retaining element. In particular, the second retaining element, with its connecting section, is supported by the support section of the first retaining element when installed. The first retaining element can form the base body of the retaining device, which is attached to the wall during installation and, when installed, supports the second retaining element, which can also be referred to as the support arm.

[0021] The first support element can have a longitudinal extension, that is, an extension along the first longitudinal axis, of between 60 and 300 millimeters, particularly between 80 and 160 millimeters. The second support element can have a longitudinal extension, that is, an extension along the second longitudinal axis, of between 100 and 500 millimeters, particularly between 140 and 320 millimeters. These values ​​are advantageous for the secure support of a partition element, especially one made of a solid glass panel, which can be used, for example, as a fixed side wall in a walk-in shower. The support device can then securely hold the partition element against the wall. Alternatively, the first support element can be a long L-shaped leg and the second support element a short L-shaped leg, or both support legs can be of the same length.

[0022] Furthermore, the first longitudinal axis and the second longitudinal axis can define a connecting plane to which the axis of rotation is perpendicular. This simplifies the rotation of the retaining elements relative to each other around the axis of rotation.

[0023] According to a first embodiment, the second retaining element can have a receiving space extending along the second longitudinal axis for receiving an upper edge section of the partition element to be held. This allows the retaining device to be placed on the upper edge of the partition element, resulting in a visually unobtrusive fastening. The second retaining element can, in particular, have a U-shaped profile with a web and two flanges projecting from it, which define the receiving space between them. The receiving space can thus be designed as a slot or, in particular, a groove open on both sides. This is especially advantageous if the partition element to be held is, in particular, a frameless glass panel that, for aesthetic reasons, should be as flush as possible with the wall when installed."As flush as possible" means that, when installed, preferably only a flexible sealant, such as silicone, is applied between the wall and the partition element, if necessary. Furthermore, the flanges can be oriented perpendicular to the connection plane. This allows the partition element to be clamped or wedged more securely between the two flanges.

[0024] At least one of the flanges can have several threaded holes for pressure or clamping screws, in particular set screws, to fix the separating element in the receiving space. To protect the separating element being held, a protective strip made of plastic, for example, can be provided, which can be inserted between the clamping screws and the separating element. Preferably, the web has an outer surface that is aligned parallel to the plane of connection. This gives the holding device, in particular the second holding element, a visually slim form with a low profile. The outer surface can lie in the plane of connection. In particular, the flanges and the web of the second holding element can be arranged in a U-shape in cross-section with respect to the second longitudinal axis.The second retaining element can therefore have a U-shaped profile, at least in sections, in whose longitudinal slot the receiving space for the separating element is formed.

[0025] According to an alternative second embodiment, the holding device can also be attached laterally to the partition element to be held. For this purpose, the second holding element can, for example, be glued to the partition element to be held or engage through an opening in the partition element in order to clamp it in the assembled state.

[0026] The axis of rotation can be located outside an imaginary extension of the receiving space. In particular, the at least one locking screw and the optional locking element are also located outside this imaginary extension of the receiving space. This allows the partition element, when installed in the receiving space, to abut the wall to which the first retaining element is attached. Preferably, the receiving space is open at both ends. In the installed state, the transition between the wall and the partition element can be sealed with conventional sealant, such as silicone.

[0027] The web and / or flanges can extend at least substantially over the entire length of the second retaining element along the second longitudinal axis. This ensures that the separating element to be held is encompassed over a considerable length, thereby increasing the stability of the connection.

[0028] The first retaining element can have a contact surface for mounting against the wall. This contact surface forms a mounting plane, which is oriented, in particular, parallel to the axis of rotation and / or perpendicular to the connection plane. This allows the first retaining element to be mounted flush against the wall, preferably directly, and attached to it. In particular, the receiving space formed on the second retaining element begins in the mounting plane of the first retaining element, or at a distance of less than 10 millimeters from the mounting plane. In particular, the distance between the mounting plane and the axis of rotation is less than 50 millimeters, preferably less than 40 millimeters, and more preferably less than 30 millimeters. In particular, this distance is greater than 5 millimeters. Preferably, the distance between the mounting plane and the axis of rotation is in the range of 10 millimeters to 25 millimeters.

[0029] Preferably, the first retaining element has at least one mounting opening for receiving a fastening element. This allows the retaining device to be attached to the wall by means of the first retaining element, in particular by screwing it in place. The at least one fastening element can be a screw. The first retaining element can have several mounting openings, which can be spaced apart from each other along the first longitudinal axis. For example, the first retaining element has two, three, or four mounting openings, which achieves good results in terms of stability.

[0030] Furthermore, the second retaining element can have an end face at its held end, i.e., the end connected to the first retaining element, which forms a lateral angle with the second longitudinal axis or the second side surface. This lateral angle can be greater than 90 degrees. This allows the second retaining element to be rotated around the axis of rotation relative to the first retaining element, even at a short distance from the mounting plane. Preferably, the lateral angle corresponds at least approximately to the sum of 90 degrees and the size of the rotation angle range. This allows the angled end face to be aligned parallel to the mounting surface in one of the two end positions defined by the limited rotation angle range, and in particular, to lie within the mounting plane. In the installed state, the end face then lies flush against the wall.

[0031] To connect the two retaining elements so that they can rotate around the axis of rotation, a coaxial connecting screw can be provided. The connecting screw can be inserted through a bore formed in one of the two retaining elements and into another bore formed in the other retaining element. The bore in one retaining element, against which the screw head of the connecting screw can be supported, can be unthreaded. The other bore can be a threaded bore into which the connecting screw can be screwed. The two bores can be concentric with, or define, the axis of rotation. The unthreaded bore can have a countersink to receive the screw head of the connecting screw in one of the retaining elements.Preferably, the unthreaded bore for the connecting screw is formed in the elongated retaining element, and the threaded bore is formed in the other retaining element. The retaining elements can be made of metal or plastic.

[0032] Furthermore, the mounting device can have a multi-part, in particular two-part, cover for concealing the two mounting elements. The cover can be made of plastic or metal. After the mounting elements have been aligned, the cover can be attached to them, thereby further improving the mounting device's appearance and simplifying surface cleaning. In particular, the cover can be bonded to the mounting elements, for example, using double-sided adhesive.

[0033] Another solution to the aforementioned problem consists of a partition arrangement with a previously described holding device and a partition element. The partition arrangement according to the invention offers the same advantages as those described in connection with the holding device according to the invention, so reference is made here, for the sake of brevity, to the description above. It is understood that all mentioned embodiments of the holding device are transferable to the partition arrangement and vice versa. Overall, the partition arrangement according to the invention is easy to manufacture and allows for simpler alignment of the partition element during on-site assembly. It is advantageous that, in the assembled state of the partition arrangement, the partition element can be aligned about the axis of rotation of the holding device within the limited range of rotation and forms a fixed partition when clamped.

[0034] When installed, the partition element rests on a fixed surface, such as a floor in a wet room, the edge of a shower or bathtub, or similar. Spacers, ranging in thickness from 1 mm to 10 mm, can be placed between the partition element and the floor. The first support element is attached to the wall and supports the second support element, which in turn is attached to the partition element. The partition element is positioned as close to the wall as possible, ideally flush with it. The installer can align or adjust the partition element, along with the second support element, around its axis of rotation within the limited range of motion.The installer can then tighten at least one locking screw, which clamps the two retaining elements against each other at the selected angle of rotation and prevents any further relative movement between them around the axis of rotation. In this clamped state, the partition element is aligned. Any resulting gap between the partition element and the wall can be sealed with a flexible sealant, such as silicone.

[0035] The partition element defines a surface plane that is aligned, in particular, parallel to the axis of rotation. This allows the partition element, attached to the second retaining element, to be rotated around the preferably vertically oriented axis of rotation within the limited range of rotation angle. One end face of the partition element faces the wall and can be positioned as close as possible to it, i.e., in the immediate vicinity or flush with the wall. "In the immediate vicinity" is defined as a distance, or joint width, of a maximum of 15 millimeters. For example, a profile rail, in particular a U-channel, can be arranged between the partition element and the wall, into which the partition element can be inserted laterally.As an alternative to the profile rail, the partition element can be extended up to the wall, such that a joint with a width of approximately 1 millimeter to 5 millimeters and preferably up to 3 millimeters is formed between the wall and the partition element, which can be sealed with flexible sealant, in particular silicone.

[0036] To further stabilize the stationary partition element, at least one angle bracket can be provided, which can be attached laterally to the partition element and to the wall. Such an angle bracket can have two hinged fittings so that it can follow the pivoting movement of the partition angle within its rotation range. A locking device to block the angle bracket's joint is not necessary because the partition assembly can be fixed at the selected rotation angle by the holding device. In principle, however, the partition assembly can also have several holding devices. For example, a first holding device can be placed on top of the partition element's edge, and at least a second holding device, such as an angle bracket, can be attached laterally to the partition element.The advantage here is that the partition arrangement can be fixed in rotation at several positions once it has been aligned around the desired angle of rotation.

[0037] The connection plane can be oriented perpendicular to the axis of rotation and / or perpendicular to the surface plane. This allows the holding device to be placed on the upper edge of the partition element, resulting in a visually unobtrusive fastening. The holding device can also be described as an adjustable stabilizing bracket. Because the partition element can be inserted from below into the receiving space between the flanges, no holes are required in the partition element. The partition element can therefore have a completely closed surface, thus improving the visual appearance of the partition assembly.

[0038] The partition element can be, in particular, a frameless shower or bathtub screen in a wet room. Specifically, the partition element can be made of safety glass, for example, tempered safety glass (ESG) or laminated safety glass (VSG). Other inherently stable materials are also possible.

[0039] The partition element can be, in particular, a fixed side panel, for example, for a walk-in shower or a bathtub with a shower area. In this way, the partition element can serve as a side panel for a niche shower, a corner shower, a pentagonal shower, a bathtub, or the like. A door can be hinged to the partition element, which is fixed to the wall with the mounting bracket.

[0041] In the Figures 1 to 3A holding device 1 according to the invention for a planar or flat partition element 2 is shown, the two together forming a partition arrangement. The partition element 2 can, for example, be a fixed side wall of a shower, which is attached to a wall 3 by means of the holding device 1. To clarify the orientation of the partition arrangement in space, spatial axes X, Y, and Z are defined in the sense of a Cartesian coordinate system associated with the wall 3 and indicated by corresponding arrows. Where terms such as horizontal, vertical, top, bottom, above, or below are used, these refer to a mounted state of the partition arrangement.

[0042] In the Figures 1 to 3The partition arrangement is shown in its assembled state. The partition element 2 rests with its lower end on the rim 4 of a shower tray, which is only partially shown. The partition element 2 rests flush against a wall 3 on its sides and can be sealed along a joint area 5 against the wall 3 using a flexible sealant, such as sanitary silicone. The support device 1 is placed on an upper edge of the partition element 2 and supports it against the wall 3. The wall 3 defines a wall plane E3, to which the spatial axes Y and Z run parallel. The partition element 2 defines a partition plane E2, which, in its assembled state, is vertically oriented and runs parallel to the spatial axis Z.

[0043] The holding device 1 according to the invention is in the Figures 4 to 16The holding device 1 has a first holding element 6 for attachment to the wall 3 and a second holding element 7 for attachment to the partition element 2, wherein the two holding elements 6, 7 are rotatably connected to each other about a rotation axis S over a limited range of rotation angles. In the mounted state, the rotation axis S runs parallel to the spatial axis Z. Figure 1 and 9 The two directions of rotation around the axis of rotation S are shown to allow the partition element 2 to be pivoted relative to the wall 3 within the limited range of rotation angles. The two directions of rotation are indicated by directional arrows R1 and R2. By pivoting the partition element 2 around the axis of rotation S, an alignment angle α formed between the wall plane E3 and the partition plane E2 can be set.

[0044] With respect to the axis of rotation S, the holding device 1 has an L-shape. The holding device 1 can be configured as an elongated form, as shown in the Figure 4 shown, or in short form, as in the Figures 4 to 16 or in the assembled state in the Figures 1 to 3 shown, designed. The second retaining element 7 has a greater longitudinal extent in the long form than in the short form. Likewise, the retaining device 1, viewed from outside the shower towards the partition element 2, can serve or be designed to attach a left side of the partition element 2 to the wall 3 or a right side of the partition element 2 to the wall 3. In the Figures 1 to 4 are left-hand embodiments of the holding device 1 and in the Figures 5 to 16 A right-hand embodiment of the holding device 1 is shown. The following explanations regarding the holding device 1 can, in turn, apply to all embodiments of the holding device 1.

[0045] The first retaining element 6 can be a short L-leg extending along or having a first longitudinal axis L6. The second retaining element 7 can correspondingly be a long L-leg extending along or having a second longitudinal axis L7. The two longitudinal axes L6, L7, or the side surfaces of the retaining elements 6, 7, enclose the alignment angle α between them.

[0046] The first retaining element 6 has a contact surface 8 for resting against the wall 3, which, in the mounted state, lies flush against the wall 3. The contact surface 8 lies in a mounting plane E8, which, in the mounted state, runs parallel to the wall plane E3. Furthermore, the first retaining element 6 has several mounting openings 9, here shown as an example of three, for attaching the first retaining element 6 to the wall 3 using (not shown) mounting elements, for example, screws. The mounting openings 9 are arranged along the first longitudinal axis L6.

[0047] The first retaining element 6 has a support section 10 against which the second retaining element 7 rests, and a fastening section for attaching it to the wall. The support section 10 widens towards the free end to provide a larger bearing surface for the second retaining element 7. Figure 8 It can be seen that a central bore 11 is formed in the support section 10, which is arranged concentrically to the axis of rotation S. The central bore 11 can be a blind hole with a thread. On an imaginary circular arc around the axis of rotation S, two further bores are formed in the support section 10, which are referred to as threaded bores 12. The threaded bores 12 can also be blind holes. Between the two threaded bores 12, an unthreaded blind hole is formed in the support section 10, which is referred to as a locking bore 13. In the Figures 11 and 12It can be seen that the locking bore 13 has a shallower hole depth than the two threaded bores 12.

[0048] The second retaining element 7 has a connecting section 14 that overlaps the support section 10. A threadless through-hole 15 is formed in the connecting section 14, which is aligned concentrically to the axis of rotation S. A connecting screw 16 engages through the through-hole 15 and is screwed into the thread of the central bore 11, thus detachably connecting the two retaining elements 6 and 7. The through-hole 15 has a countersink to receive the screw head of the connecting screw 16. The two retaining elements 6 and 7 are rotatably connected to each other about the axis of rotation S via the connecting screw 16.

[0049] Furthermore, two elongated holes 17 are formed in the connecting section 14, which are aligned with the threaded bores 12 in the first retaining element 6. Figure 10It can be seen that the two elongated holes 17 extend along an imaginary arc segment K, the center M of which lies on the axis of rotation S. A locking screw 18 extends through each elongated hole 17 and is screwed into the respective threaded bore 12 of the first retaining element 6. It is understood that a modified embodiment with only one elongated hole 17 and one locking screw 18 is also possible. The axial distance between the threaded bore 12 of a locking screw 18 and the pivot axis S is, in particular, less than three times the diameter d18 of the screw head 19 of the locking screw, preferably less than twice the diameter d18. When using two locking screws 18, the angle formed between the axes of the threaded bores 12 about the pivot axis S is, in particular, between 70 and 110 degrees.

[0050] The elongated holes 17 are stepped, meaning they have recesses for receiving the screw heads 19 of the locking screws 18 and a through-hole for the screw shank. The screw axes of the locking screws 18 run parallel to the axis of rotation S. When the two locking screws 18 are screwed into the threaded holes 12, the two retaining elements 6, 7 are preloaded against each other, thus preventing relative movement between the two retaining elements 6, 7 about the axis of rotation S (preloaded state). If, on the other hand, the two locking screws 18 are slightly loosened but still screwed into the threaded holes 12 (loosened state), the retaining element 7 can be rotated about the axis of rotation S relative to the first retaining element 6 over the limited range of rotation angle.When the second retaining element 7 is rotated relative to the first retaining element 6 about the axis of rotation S, the locking screws 18 abut against the respective end of the holes 20, 21, 22, 23 of the elongated holes 17 in both directions of rotation R. The hole ends 20, 21, 22, 23 lie on the arc segment K. In the end positions where the locking screws 18 abut against the hole ends 20, 21, 22, 23, the second retaining element 7 cannot be rotated further, so that the length D17 of the extension of the respective elongated hole 17 following the arc segment K and the diameter d18 of the screw head 19 of the respective locking screw 18 define and limit the range of rotation.

[0051] If the second retaining element 7 is now rotated relative to the first retaining element 6 about the axis of rotation S in the first direction of rotation R1, the screw heads 19 of the locking screws 18 strike, with regard to the Figures 13 and 14, at the right ends 21, 23 of the two elongated holes 17. In this end position, the second retaining element 7 can only be rotated in the second direction R2. If, on the other hand, the second retaining element 7 is rotated relative to the first retaining element 6 about the axis of rotation S in the second direction R2, the screw heads 19 of the locking screws 18, with regard to the Figures 15 and 16 , at the left ends 20, 22 of the two elongated holes 17. In this end position, the second retaining element 7 can only be rotated in the first direction R2. In this way, the rotation angle range is limited to 4 degrees as an example. If the locking screws 18 are again arranged centrally between the two ends 20, 21, 22, 23 of the elongated holes 17, as in the Figure 10As shown, the holding device 1 is in its initial position. In this position, the alignment angle α formed between the two longitudinal axes L6 and L7 is 90 degrees. Therefore, the alignment angle α can be adjusted between 88 degrees and 92 degrees using the holding device 1. In other words, the second holding element 7 can be adjusted relative to the first holding element 6 with a rotation angle ϕ of up to two degrees in the first direction of rotation R1 or up to two degrees in the second direction of rotation R2. In the initial position, the rotation angle ϕ is zero degrees.

[0052] For easy assembly and to ensure the initial position of 90 degrees can be precisely assumed, the holding device 1 optionally features a locking element 24. The locking element 24 is inserted into a retaining bore 25 formed in the second holding element 7. The locking element 24 may be threaded so that it can be screwed into a thread in the retaining bore 25. The retaining bore 25 is formed as a through bore in the connecting section 14 of the second holding element 7 and, in the initial position, is aligned with the locking bore 13 in the first holding element 6 below. To lock the initial position, the locking element 24 can be moved section by section into the locking bore 13 parallel to the axis of rotation S. Relative movement between the two holding elements 6 and 7 is then blocked. This locked state is indicated in the Figure 11 shown. In Figure 12A released state is shown in which the locking element 24 is arranged outside the locking bore 13 and is only seated in the retaining bore 25. The locking element 24 has a length that is less than or equal to the depth of the retaining bore 25, so that the locking element 24 does not protrude beyond the retaining bore 25 in the released state. The axial distance between the locking bore 13 and the pivot axis is, in particular, smaller than the radius of the circular arc K. Preferably, the locking bore 13 lies on an angle bisector between the two threaded bores 12.

[0053] The second retaining element 7 has an end face 27 at its longitudinal end 26 on the connection side, which forms a lateral angle β with the second longitudinal axis L7 or the side surface of the retaining element 7. The lateral angle β corresponds to the sum of 90 degrees and the size of the rotation angle range, which is assumed here to be 4 degrees as an example. Thus, the lateral angle β can be, for example, 94 degrees. Figure 13 It can be seen that in the 92-degree position of the holding device 1 shown there, the end face 27 is arranged parallel to or in the mounting plane E8. Thus, the end face 27, in addition to the hole ends 21, 23, can act as a further stop to limit the rotation angle range in which the second holding element 7, at an alignment angle α of 92 degrees, is in contact with the wall 3 with its end face 27. Figure 15It can be seen that, due to the relative movement of the two retaining elements 6, 7 around the axis of rotation S, the end face 27 is inclined to the mounting plane E8 in the 88 degree position, whereby the angle between the mounting plane E8 and the end face 27 can correspond to the size of the rotation angle range, here by way of example 4 degrees.

[0054] Starting from the fastening end 26 to a free longitudinal end 28, the second retaining element 7 has a receiving space 29 for receiving the upper edge section of the separating element 2. The receiving space 29 extends continuously between the two longitudinal ends 26, 28 parallel to the second longitudinal axis L7. The axis of rotation S is located outside an imaginary extension of the receiving space 29. The receiving space 29 is open at the bottom, bounded laterally by two flanges 30, 31 aligned parallel to each other, and at the top by a web 32 of the second retaining element 7. In cross-section with respect to the second longitudinal axis L7, the flanges 30, 31 and the web 32 form a U-profile.

[0055] In Figure 8It can be seen that the flange 30, which faces the first retaining element 6, has several openings 33 for clamping screws 34. The clamping screws 34 can be set screws, preferably made of metal. Plastic plates (not shown) are attached to the tips of the clamping screws 34 to prevent damage to the separating element 2 by the clamping screws 34. The clamping screws 34 can also be made of plastic to protect the separating element 2. The openings 33 can also be formed on the other flange 31 or in both flanges 30 and 31. Furthermore, a strip-shaped insert element 35, for example, can be inserted between the flange 31 and the separating element 2 in the receiving space 29. Additional insert elements and edge protectors for protecting the separating element 2 and / or against water ingress can also be provided.

[0056] Furthermore, the holding device 1 has a cover 36 which, after alignment, is placed on the two holding elements 6, 7 and may be bonded to them. Here, the cover 36 is designed in multiple parts to ensure better adaptation of the cover 36 to the two holding elements 6, 7, which are movable relative to each other. In principle, the cover 36 can also be designed as a single piece if its material allows for a certain degree of flexibility or offers a sufficiently large interior space for the two holding elements 6, 7 in their different rotational positions. The cover 36 shown here is designed in two parts and has a first cover part 37 for covering the first holding element 6 and a second cover part 38 for covering the second holding element 7. Concentric to the axis of rotation D, the two cover parts 37, 38 each have a curved edge region 39, 40, which are formed opposite to each other.The edge region 39 of the first cover part 37 is convex and the edge region 40 of the second cover part 38 is concave. Thus, the two cover parts 37, 38 can interlock at any rotation angle ϕ and cover the two retaining elements 6, 7 from above in a flat and largely gap-free manner.

[0057] To mount the partition assembly, the holding device 1 is attached to the upper edge of the partition element 2. For this purpose, the partition element 2 is inserted into the receiving space 29 of the U-shaped second holding element 7. Because the receiving space 29, or rather the second holding element 7, is open at both longitudinal ends 26, 28, the holding device 1 can be positioned on the partition element 2 so that the partition element 2 is flush with the mounting surface E8 or has a gap of approximately 1 to 3 millimeters. The clamping screws 34 can be lightly tightened to fix the partition element 2 in the receiving space 29.

[0058] To attach the mounting device 1 to the wall 3, the partition element 2 is set up and the first mounting element 6 is leveled. Then, fastening screws can be screwed into the wall 2 through the mounting holes 9.

[0059] By loosening the locking screws 18 and the locking element 24, the separating element 2, together with the second retaining element 7, can be rotated about the axis of rotation S over the limited range of rotation relative to the wall 2 or the first retaining element 6. Once the separating element 2 is aligned at the desired angle of rotation ϕ, the two retaining elements 6 and 7 can be fixed at the set angle of rotation ϕ relative to each other by tightening the locking screws 18. The connecting screw 16 can also be tightened to further increase the stability of the connection.

[0060] If the partition element 2 needs to be aligned with the wall 2 at an angle α of exactly 90 degrees, it can be moved into its initial position. The initial position is easily identifiable for the installer because, when the partition element 2 is pivoted about the axis of rotation S, it is reached when the locking element 24 can be pressed into the locking bore 13 or moved section by section. The initial position can also be fixed by tightening the locking screws 18.

[0061] Finally, the clamping screws 34 are tightened and the cover 36 is placed on the holding device 1 and glued in place if necessary. Reference symbol list
