[0001] TITLE

[0002] STORAGE ARRANGEMENT FOR AN ACTUATOR UNIT OF A CONCEALED TIVER BOX AND SCREW CONNECTION

[0003] TECHNICAL AREA

[0004] The present invention relates to a storage arrangement for the storage of an actuating unit in front of a cistern according to claim 1, a sanitary arrangement according to claim 14 and a screw connection according to claim 15.

[0005] STATE OF THE ART

[0006] Storage arrangements for actuating units have become known from the prior art, for example from EP 1 300 520.

[0007] PRESENTATION OF THE INVENTION

[0008] Based on this prior art, the present invention aims to provide a bearing arrangement for mounting an actuating unit that overcomes the disadvantages of the prior art. In particular, it is an object of the present invention to provide a bearing arrangement for mounting an actuating unit that is easier to assemble.

[0009] The bearing arrangement according to claim 1 solves these and other problems. Accordingly, a bearing arrangement for the bearing of an actuating unit in front of a cistern comprises a support element with at least one threaded opening with an internal thread, a bearing frame with a bearing structure for bearing an actuating unit and at least one fastening opening, and at least one bolt element with a shaft extending along a central axis, which has an external thread and a bearing section, and with an actuating tab.

[0010] The external thread is interrupted circumferentially by at least one longitudinal groove extending along the central axis through the external thread. The interruption is such that at least one external thread segment and at least one groove segment without an external thread are provided.

[0011] The internal thread is interrupted circumferentially by at least one longitudinal groove extending through the internal thread. The interruption is such that at least one internal thread segment and at least one groove segment without an internal thread are provided.

[0012] In an assembly position, the bolt element is oriented towards the threaded opening in such a way that the at least one external thread segment lies in the area of ​​the at least one internally threadless groove segment and the at least one internal thread segment lies in the area of ​​the at least one externally threadless groove segment, such that the bolt element is freely displaceable in the threaded opening in the direction of the central axis.

[0013] In a locked position of the bolt element, at least one external thread segment engages with at least one internal thread segment. Furthermore, the bearing section lies in the mounting opening and the actuating tab rests against the bearing frame with a stop surface.

[0014] The arrangement of the threaded segments has the advantage that, when the bolt element moves from the mounting position to the locking position, the stop surface can be moved towards the support element due to the thread pitch, thereby also moving the bearing frame towards the support element. During installation, the bearing frame rests against the edge of a building wall and can be clamped to the edge of the building wall due to the described movement.

[0015] During assembly, the bolt element with its shaft is inserted through the mounting hole, and the shaft can be slid into the threaded opening. Due to the unthreaded groove segment, the two threads do not engage with each other. This means that during assembly, the external thread is not engaged with the internal thread. In the locked position, the two threads are engaged. The shaft's ability to slide along the central axis during assembly allows the bolt element to be positioned very easily and quickly relative to the support element. This enables tool-free, rapid assembly. The bearing structure for the actuating unit can be provided, for example, by cutouts or undercuts in the bearing frame.

[0016] The number of external thread segments preferably corresponds to the number of non-external threaded groove segments. The number of internal thread segments preferably corresponds to the number of non-internal threaded groove segments. The number of external thread segments preferably corresponds to the number of internal thread segments.

[0017] The support element can be part of a cistern or it can be connected to the cistern. In its installed position, the cistern and the support element are positioned behind a partition wall, and the bearing frame rests on the front of the partition wall. The at least one bearing bolt protrudes through an opening in the partition wall and extends from the bearing frame to the support element.

[0018] During assembly, the bolt element can be moved along its central axis, as mentioned. This is a linear movement along the central axis. From the assembly position, the bolt element can be moved into the locking position, a pivoting movement around the central axis of the shaft. This pivoting movement engages the aforementioned threaded segments.

[0019] When the bolt element pivots about the central axis starting from the mounting position, the at least one external thread segment preferably engages in the at least one internal thread segment in such a way that, as the pivoting movement continues, a longitudinal movement results between the bolt element and the support element, such that the bearing frame is moved towards the support element and / or subjected to a force in the direction of the support element.

[0020] Preferably, the at least one external thread segment and the at least one externally threadless groove segment are designed asymmetrically relative to each other. Preferably, the at least one internal thread segment and the at least one internally threadless groove segment are designed asymmetrically relative to each other. The asymmetrical design is such that, in the assembly position, the bolt element can only be inserted into the threaded opening in a single, determined orientation. In other words, the asymmetrical design is such that the threaded segments and the groove segments are arranged in a non-uniform distribution around the circumference.

[0021] Preferably, at least two external thread segments and at least two non-external threaded groove segments are arranged, wherein one of the external thread segments and one of the non-external threaded groove segments extends over a larger arc angle than another of the external thread segments and another of the non-external threaded groove segments.

[0022] Preferably, at least two internal thread segments and at least two non-internal threaded groove segments are arranged, wherein one of the internal thread segments and one of the non-internal threaded groove segments extends over a larger arc angle than another of the internal thread segments and another of the non-internal threaded groove segments.

[0023] In a particularly preferred embodiment, three external thread segments, three internal thread segments, and three groove segments are provided. All these segments preferably extend over different arc angles.

[0024] Preferably, when pivoting from the mounting position, starting from the aforementioned determined orientation, into the locking position, the bolt element is pivoted by an angle in the range of 90° to 180°. An angle of 90° or 180° is particularly preferred.

[0025] Preferably, the arc angle of an external thread segment is smaller than the arc angle of an internally threadless groove segment associated with said external thread segment. Preferably, the arc angle of an internal thread segment is smaller than the arc angle of an externally threadless groove segment associated with said internal thread segment.

[0026] This design ensures that when the shaft with the external thread protrudes into the threaded opening with the internal thread, there is radial play between the at least one external thread segment and the internally unthreaded groove segment, or between the at least one internal thread segment and the externally unthreaded groove segment, so that axial displacement in the assembly position can occur without the threads jamming.

[0027] Preferably, an outer transition between the side surfaces of the external thread segment facing the groove segment and the nominal diameter of the external thread segment is formed with a convex curve. Preferably, an inner transition between the side surfaces of the external thread segment facing the groove segment and the base of the groove segment is formed with a concave curve. Preferably, an inner transition between the side surfaces of the internal thread segment facing the groove segment and the inner diameter of the internal thread segment is formed with a convex curve. Preferably, an outer transition between the side surfaces of the internal thread segment facing the groove segment and the base of the groove segment is formed with a concave curve.

[0028] Preferably, the fastening opening has a cross-sectional shape that is complementary to the cross-sectional shape of the shaft with the at least one external thread segment and the at least one externally threadless groove segment.

[0029] A complementary design means that the two cross-sectional shapes are compatible or similar to each other. The term "cross-sectional shape" used here refers to the clearance profile of the mounting opening or the threaded opening when viewed along its respective central axis.

[0030] This ensures that the bolt element is already in the specified determined position when the bolt element is inserted.

[0031] Preferably, the cross-sectional shape of the fastening opening, viewed in the direction of its central axis, is the same as the cross-sectional shape of the threaded opening, viewed in the direction of its central axis.

[0032] Preferably, the bearing section has a cross-sectional shape that allows the bolt element to pivot relative to the mounting opening when the bolt element and bearing section are located in the mounting opening. Preferably, the bearing section is cylindrical.

[0033] Preferably, the said stop surface rests against a front surface of the bearing frame.

[0034] Preferably, the relative movement between the bolt element and the bearing frame is limited exclusively by the contact of the stop surface with the front surface and by the protrusion of the shaft through the mounting opening. This means that the bolt element is freely movable relative to the bearing frame in the direction of its central axis until the stop surface comes into contact with the front surface.

[0035] Preferably, the thread flanks of the external and internal threads are asymmetrically formed in cross-section, with the thread flank oriented towards the support element being at a greater angle to the central axis than the thread flank oriented towards the bearing frame. The external and internal threads are particularly preferably designed as saw threads.

[0036] When assembled, the shaft section experiences a tensile load from the support element towards the bearing element. The asymmetrical design of the thread allows this tensile load to be transferred more effectively from the external thread to the internal thread.

[0037] Alternatively, the external thread and the internal thread are designed as metric threads.

[0038] Preferably, the internal and external threads have a thread pitch in the range of 4 mm to 12 mm, particularly in the range of 6 mm to 10 mm, and most preferably 8 mm. The internal and external threads are preferably multi-start threads. Multi-start threads with 2 to 6 threads are particularly preferred. A thread with 5 threads is especially preferred.

[0039] In a first variant, the actuating tab has a locking cam, and the bearing frame has a locking recess. In the locked position, the locking cam engages in the locking recess. In a second variant, the actuating tab has a locking recess, and the bearing frame has a locking cam. In the locked position, the locking cam engages in the locking recess.

[0040] The actuating tab protrudes from the shaft at an angle to the central axis. The bearing section is located between the actuating tab and the external thread. The actuating tab allows for tool-free manipulation of the bolt element.

[0041] Preferably, the support element has a through-opening which is laterally limited by frame sections, wherein a flange section projecting into the through-opening is arranged on each of two frame sections opposite the through-opening, with the threaded opening being arranged on the flange section.

[0042] Preferably, the bearing frame has a through-opening which is laterally limited by frame sections, wherein the fastening opening is arranged on two frame sections opposite the through-opening.

[0043] A sanitary arrangement comprises a storage arrangement as described above and an actuating unit, wherein the actuating unit is mounted on the storage structure on the storage frame.

[0044] The actuating unit preferably has actuating pockets which are pivotably mounted on a frame of the actuating unit. The frame can be connected to the bearing structure of the bearing frame.

[0045] Preferably, the sanitary arrangement further comprises a cistern with a flush valve, wherein said support element is part of the cistern or connected to the cistern. The flush valve can be actuated by the actuating unit.

[0046] A further object of the present invention is to provide a screw connection for sanitary installations that is easy to screw together. This and other objects are solved by the screw connection according to claim 15. Accordingly, a screw connection comprises at least one threaded opening with an internal thread and at least one bolt element with a shank extending along a central axis and having an external thread. The external thread is interrupted circumferentially by at least one longitudinal groove extending along the central axis through the external thread. The interruption is such that at least one external thread segment and at least one groove segment without an external thread are provided.

[0047] The internal thread is interrupted circumferentially by at least one longitudinal groove extending through the internal thread. The interruption is such that at least one internal thread segment and at least one groove segment without an internal thread are provided.

[0048] In an assembly position, the bolt element is oriented towards the threaded opening in such a way that the at least one external thread segment lies in the area of ​​the at least one internally threadless groove segment and the at least one internal thread segment lies in the area of ​​the at least one externally threadless groove segment, such that the bolt element is freely displaceable in the threaded opening in the direction of the central axis.

[0049] In an engagement position of the bolt element, the at least one external thread segment is in engagement with the at least one internal thread segment.

[0050] During assembly, the bolt element with its shank is inserted through the mounting hole, and the shank can be pushed into the threaded opening. Due to the threadless groove segment, the two threads do not engage with each other. This means that during assembly, the external thread is not engaged with the internal thread. In the engaged position, the two threads are engaged with each other.

[0051] The number of external thread segments preferably corresponds to the number of externally threadless groove segments. The number of internal thread segments preferably corresponds to the number of internally threadless groove segments. The number of external thread segments preferably corresponds to the number of internal thread segments.

[0052] During assembly, the bolt element can be moved along its central axis, as mentioned. This is a linear movement along the central axis. From the assembly position, the bolt element can be moved into the locking position, a pivoting movement around the central axis of the shaft. This pivoting movement engages the aforementioned threaded segments.

[0053] When the bolt element pivots about the central axis starting from the mounting position, the at least one external thread segment preferably engages in the at least one internal thread segment in such a way that, as the pivoting movement continues, a longitudinal movement between the bolt element and the support element results, such that the bearing frame is moved towards the support element.

[0054] Preferably, the at least one external thread segment and the at least one groove segment without external threads are designed asymmetrically to each other. Preferably, the at least one internal thread segment and the at least one groove segment without internal threads are designed asymmetrically to each other. The asymmetrical design is such that, in the assembly position, the bolt element can only be inserted into the threaded opening in a single, determined orientation.

[0055] In other words, the asymmetrical design is such that the thread segments and the groove segments are arranged in an uneven distribution around the circumference.

[0056] Preferably, at least two external thread segments and at least two non-external threaded groove segments are arranged, wherein one of the external thread segments and one of the non-external threaded groove segments extends over a larger arc angle than another of the external thread segments and another of the non-external threaded groove segments.

[0057] Preferably, at least two internal thread segments and at least two non-internal threaded groove segments are arranged, wherein one of the internal thread segments and one of the non-internal threaded groove segments extends over a larger arc angle than another of the internal thread segments and another of the non-internal threaded groove segments.

[0058] In a particularly preferred embodiment, three external thread segments, three internal thread segments, and three groove segments are provided. All these segments preferably extend over different arc angles.

[0059] Preferably, when pivoting from the mounting position, starting from the aforementioned determined orientation, into the locking position, the bolt element is pivoted by an angle in the range of 90° to 180°. An angle of 90° or 180° is particularly preferred.

[0060] Preferably, the arc angle of an external thread segment is smaller than the arc angle of an internally threadless groove segment associated with said external thread segment. Preferably, the arc angle of an internal thread segment is smaller than the arc angle of an externally threadless groove segment associated with said internal thread segment.

[0061] This design ensures that when the shaft with the external thread protrudes into the threaded opening with the internal thread, there is radial play between the at least one external thread segment and the internally unthreaded groove segment, or between the at least one internal thread segment and the externally unthreaded groove segment, so that axial displacement in the assembly position can occur without the threads jamming.

[0062] Preferably, an outer transition between the side surfaces of the external thread segment facing the groove segment and the nominal diameter of the external thread segment is formed with a convex curve. Preferably, an inner transition between the side surfaces of the external thread segment facing the groove segment and the base of the groove segment is formed with a concave curve. Preferably, an inner transition between the side surfaces of the internal thread segment facing the groove segment and the inner diameter of the internal thread segment is formed with a convex curve. Preferably, an outer transition between the side surfaces of the internal thread segment facing the groove segment and the base of the groove segment is formed with a concave curve.

[0063] Preferably, the thread flanks of the external and internal threads are asymmetrical in cross-section. Particularly preferably, the external and internal threads are designed as saw threads. Alternatively, the external and internal threads are designed as metric threads.

[0064] Preferably, the internal and external threads have a thread pitch in the range of 4 mm to 12 mm, particularly in the range of 6 mm to 10 mm, and most preferably 8 mm. The internal and external threads are preferably multi-start threads. Multi-start threads with 2 to 6 threads are particularly preferred. A thread with 5 threads is especially preferred.

[0065] Preferably, the support element, the bearing frame and the bolt element are made of plastic both at the bearing arrangement and at the screw connection.

[0066] Further embodiments are specified in the dependent claims.

[0077] DESCRIPTION OF PREFERRED EXECUTION FORMS

[0078] The figures show a bearing arrangement according to a preferred embodiment of the present invention and a screw connection according to a preferred embodiment of the present invention.

[0079] Figures 1a / 1b show a perspective view of a bearing arrangement 1 according to the invention in a preferred embodiment. The bearing arrangement is designed to support an actuating unit for triggering a flush on a cistern.

[0080] The bearing arrangement 1 comprises a support element 2, a bearing frame 5, and at least one bolt element 8. Two bolt elements 8 are arranged here. The support element 2 and the bearing frame 5 are connected to each other by the at least one bolt element 8. In the connected state, the support element 2 and the bearing frame 5 are spaced apart from each other. Typically, the support element 2 is located behind a partition wall and is connected to, or is part of, a cistern. The bearing frame 5 is located in front of the partition wall and rests against its front surface. When the at least one bolt element 2 is actuated, the bearing frame 5 is clamped against the front surface of the partition wall. The at least one bolt element 2 thereby pulls the bearing frame 5 towards the stationary support element 2.

[0081] The screw connection comprises a threaded opening 2 with an internal thread 4 and a bolt element 8 with an external thread 10. The following description applies equally to the bearing arrangement 1 and / or to the screw connection.

[0082] The support element 2 has at least one threaded opening 3 with an internal thread 4. In the illustrated embodiment, two threaded openings 3 are arranged on the support element 2. Preferably, the number of threaded openings 3 is equal to the number of bolt elements 2.

[0083] The bearing frame 5 has a bearing structure 6 for supporting the actuating unit and at least one mounting opening 7. The at least one bolt element 8 is passed through said mounting opening 7. In the illustrated embodiment, two mounting openings 7 are arranged on the bearing frame 2. Preferably, the number of mounting openings 7 is equal to the number of bolt elements 2.

[0084] The at least one bolt element 8 comprises a shaft 9 extending along a central axis M, which has an external thread 10 and a bearing section 11, and an actuating tab 12. The bearing section 11 is located between the external thread 10 and the actuating tab 12. The actuating tab 12 is designed so that it can be easily gripped by a user. The actuating tab 12 projects from the shaft substantially perpendicular to the central axis M. Here, the actuating tab 12 has a surface section 36 from which a grip section 37 projects.

[0085] The external thread 10 is interrupted circumferentially by at least one longitudinal groove 13. The at least one longitudinal groove 13 extends along the central axis M through the external thread 9. At the location of the longitudinal groove 13, the thread is completely interrupted circumferentially. The external thread 10 is interrupted circumferentially such that at least one external thread segment 14 and at least one non-external threaded groove segment 15 are provided. The at least one external thread segment 14 and the at least one non-external threaded groove segment 15 are arranged adjacent to each other around the circumference.

[0086] The internal thread 4 is also interrupted circumferentially by at least one longitudinal groove 16 extending through the internal thread 4. The at least one longitudinal groove 16 extends along the central axis of the internal thread 4 through the internal thread 4. The internal thread 4 is interrupted circumferentially such that at least one internal thread segment 17 and at least one groove segment 18 without an internal thread are provided. The at least one internal thread segment 17 and the at least one groove segment 18 without an internal thread are arranged adjacent to each other around the circumference.

[0087] In Figures 1a, 1b, and 4a, the at least one bolt element 8 is shown in an assembly position. In this position, the bolt element 8 is oriented towards the threaded opening 3 such that the at least one external thread segment 14 lies within the area of ​​the at least one internally threadless groove segment 18, and the at least one internal thread segment 17 lies within the area of ​​the at least one externally threadless groove segment 15. Due to this positioning, the bolt element 8 is freely displaceable in the threaded opening 3 in the direction of the central axis M. In Figure 4a, the cross-section of the bolt element 8 is shown with a gray tint for clarity. In summary, the segments are designed such that no engagement occurs between the external thread and the internal thread in the assembly position.

[0088] Starting from the mounting position, the bolt element 8 can be pivoted about its central axis M into the locking position. The pivoting movement is illustrated by arrows S in Figure 1a. The locking position is shown in Figures 2 and 4b. When pivoting from the mounting position to the locking position, the bolt element 8 is pivoted by an angle between 90° and 180°. In the embodiment shown in the figures, the angle is 180°.

[0089] When moving into the locking position, the external thread and the internal thread engage together. In the locked position of the bolt element 8, the at least one external thread segment 14 engages with the at least one internal thread segment 17. Furthermore, as can be seen from Figure 2, the bearing section 10 is located in the mounting opening 7 and the actuating tab

[0090] 11 rests against the bearing frame 5 with a stop surface 12. The stop surface is located here.

[0091] 12 on a front surface 35 on the bearing frame 5.

[0092] During the pivoting movement of the bolt element 8 about the central axis M from the mounting position, the at least one external thread segment 14 engages with the at least one internal thread segment 17. This engagement results in a longitudinal movement between the bolt element 8 and the support element 2 as the pivoting movement continues, such that the bearing frame 5 is moved towards the support element 2 and / or subjected to a force in the direction of the support element 2, thereby pressing the bearing frame 5 against the front surface of a partition wall. The extent of the movement is defined by the pitch of the threads of the two thread segments 14 and 17. The contact between the stop surface 12 and the front surface 35 ensures that the movement of the bolt element 8 is transmitted to the bearing frame 5. The movement or force of the bearing frame 5 towards the support element 2 is represented by an arrow B in Figure 2.Typically, the aforementioned pre-wall is located in the space Z between the bearing frame 5 and the support element 2. A preferred arrangement of threaded segments 14, 17 and groove segments 15, 18 is now explained with reference to Figures 3, 4a and 4b.

[0093] Preferably, the at least one external thread segment 14 and the at least one externally threadless groove segment 15 as well as the at least one internal thread segment 17 and the at least one internally threadless groove segment 18 are each designed asymmetrically such that in the assembly position the bolt element 8 can be inserted into the threaded opening 3 exclusively in a single determined orientation.

[0094] This asymmetrical design can be clearly seen in Figure 3. The threaded opening 3 is shown on the left side of Figure 3, and the external thread 10 is shown on the right side of the figure.

[0095] Preferably, at least two, here three, externally threaded segments 14 and at least two, here three, externally threadless groove segments 15 are arranged. One of the externally threaded segments 14 and one of the externally threadless groove segments 15 extend over a larger arc angle than another of the externally threaded segments 14 and another of the externally threadless groove segments 15. The arc angles in Figure 3 bear the reference numerals a14-1, a14-2 and a14-3 for the externally threaded segments 14 and a15-1, a15-2 and a15-3 for the externally threadless groove segments 15.

[0096] In the illustrated embodiment, the arc angles a14-1, a14-2, and a14-3 of the external thread segments 14 are each of different sizes. Likewise, in the illustrated embodiment, the arc angles a15-1, a15-2, and a15-3 of the non-externally threaded groove segments 15 are each of different sizes. This achieves the aforementioned asymmetrical arrangement.

[0097] Similarly, in the present embodiment, at least two, here three, internal thread segments 17 and at least two, here three, internal threadless groove segments 18 are arranged for the arrangement of the external thread segments 14 and the external threadless groove segments 15. One of the internal thread segments 17 and one of the internal threadless groove segments 18 extends over a larger arc angle than another of the internal thread segments 17 and another of the internal threadless groove segments 18. The arc angles in Figure 3 bear the reference numerals a17-1, a17-2 and a17-3 for the internal thread segments 17 and a18-1, a18-2 and a18-3 for the internal threadless groove segments 18.

[0098] Preferably, the arc angles a14-1, a14-2 and a14-3 of the external thread segments 14 are smaller than the arc angles a18-1, a18-2 and a18-3 of an internally threadless groove segment 18 associated with the respective external thread segment 14. Preferably, the arc angles a17-1, a17-2 and a17-3 of the internal thread segment 17 are smaller than the arc angles a15-1, a15-2 and a15-3 of an externally threadless groove segment 15 associated with the respective internal thread segment 17.

[0099] In the illustrated embodiment, the outer transition 19 between the side surfaces 20 of the external thread segment 14, which face the groove segment 15, and the nominal diameter of the external thread segment 14 is formed with an optional convex radius. Likewise, an inner transition 21 between the side surfaces 20 of the external thread segment 14, which face the groove segment 15, and the base surface 22 of the groove segment 15 is formed with an optional concave radius. Furthermore, an inner transition 38 between the side surfaces 23 of the internal thread segment 17, which face the groove segment 18, and the inner diameter of the internal thread segment 17 is formed with an optional convex radius.Furthermore, an outer transition 24 between the side surfaces 23 of the internal thread segment, which are directed towards the groove segment 18, and the base surface 25 of the groove segment is formed with a concave rounding.

[0100] Figures 1a / 1b further show that the fastening opening 7 has a cross-sectional shape that is complementary to the cross-sectional shape of the shaft 9 with the at least one externally threaded segment 14 and the at least one non-externally threaded grooved segment 15. The cross-sectional shape of the fastening opening 7, viewed along its central axis, is the same as the cross-sectional shape of the threaded opening 3, viewed along its central axis.

[0101] Figure 2 further shows that the bearing section 11 has a cross-sectional shape which allows the bolt element 8 to pivot relative to the mounting opening 7 when the bolt element 8 is in the mounting opening 7 with the bearing section 11. The bearing section 11 is preferably cylindrical.

[0102] Figure 5 shows that the actuating tab 12 has a locking cam 28 and that the bearing frame 5 has a locking recess 29. In the locked position, the locking cam 28 engages in the locking recess 29. This engagement secures the bolt element 8 to the bearing frame 5 in the locked position.

[0103] Figures 6a and 6b show the cross-sectional shape of the thread flanks 26 and 27 of the external thread 10 and the internal thread 4. The thread flanks 26 and 27 are asymmetrically shaped in cross-section. The angle of one thread flank 26 to the central axis M differs from the angle of the other thread flank 27. In the illustrated configuration, the thread flank 26, which faces the support element 2, is at a larger angle to the central axis M than the thread flank 27, which faces the bearing frame 5. Due to this asymmetrical design, tensile forces applied to the shaft along the central axis from the support element 2 to the bearing frame 5 are more efficiently transferred from the external thread to the internal thread.

[0104] In the illustrated embodiment, the support element 2 has a through-opening 30, which is laterally bounded by frame sections 31, wherein a flange section 32 projecting into the through-opening 30 is arranged on each of two frame sections 31 opposite the through-opening 30, the threaded opening 3 being arranged on the flange section. The bearing frame 5 has a through-opening 33, which is laterally bounded by frame sections 34, wherein the fastening opening 7 is arranged on two frame sections 34 opposite the through-opening 33.
