Description

[0001] TITLE

[0002] INSTALLATION ARRANGEMENT FOR A CONCEALED TIVER BOX

[0003] TECHNICAL AREA

[0004] The present invention relates to a mounting arrangement for a storage arrangement for the storage of an actuating unit in front of a cistern according to claim 1, a storage arrangement for the storage of an actuating unit in front of a cistern according to claim 15 and a sanitary arrangement according to claim 19.

[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 mounting arrangement for the bearing of an actuating unit that overcomes the disadvantages of the prior art. In particular, it is an object of the present invention to provide a mounting arrangement that can be used in various configurations or that can be used in the event of a defect in the bearing of a bearing frame that supports the actuating unit.

[0009] The mounting arrangement for a bearing arrangement for mounting an actuating unit in front of a cistern according to claim 1 solves these and other problems. Accordingly, a mounting arrangement comprises a support element, which is positioned in the installation position in front of a cistern, and at least one bolt element with a shaft extending along a central axis. The mounting arrangement further comprises at least one adapter element, wherein the adapter element has a connecting section for firmly connecting the adapter element to the support element and a bearing opening. The bearing opening and the shaft each have a locking structure designed such that, in a locked position, the bolt element can be secured via the locking structures on the adapter element.

[0010] The adapter element can be connected to the support element so firmly that, when connected, the adapter element remains in a fixed position relative to the support element. The connection between the adapter element and the support element is preferably such that it can be disconnected without causing damage.

[0011] 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. The at least one bearing bolt protrudes through an opening in the partition wall and extends from the bearing frame mentioned below to the support element.

[0012] Preferably, the connecting section has two spaced-apart side walls that laterally define a receiving space. The support element has at least one flange section, which, in the assembled state, projects between the side walls into the receiving space. Preferably, the flange section projects into the receiving space with a slight amount of play. This play simplifies assembly. In the locking position described below, the play can be eliminated by moving the bearing element towards the support element.

[0013] Preferably, the bearing opening extends through one of the two side walls. The other of the two side walls has an opening. The bearing opening and the opening are arranged relative to each other such that the shaft can be guided through both the bearing opening and the opening. The side wall in which the bearing opening is located preferably has a greater thickness than the side wall in which the opening is located.

[0014] Preferably, the central axis of the bearing opening runs collinearly with the central axis of the opening.

[0015] In a first preferred embodiment, the adapter element has at least one locking lug and the support element has at least one locking recess. The at least one locking lug engages in the locking recess. In a second preferred embodiment, the support element has at least one locking lug and the adapter element has at least one locking recess. The at least one locking lug engages in the locking recess.

[0016] Preferably, the aforementioned at least one locking lug is arranged on a spring leg, in particular by integral part thereof. The spring leg is elastically deformed during the assembly of the adapter element.

[0017] Particularly preferably, two spring arms are arranged next to one of the side walls described above. The side wall is preferably located between the two spring arms. Preferably, the side wall has a greater width than the two spring arms.

[0018] Preferably, the support element has at least one further bearing opening with a further locking structure.

[0019] The additional locking structure of the support element is preferably also a locking structure, which serves to accommodate another bolt element. For example, it is conceivable that during maintenance, the locking structure between the additional bolt element and the additional bearing opening could become defective. This could occur on the side of the bearing opening and / or on the side of the additional bolt element. The adapter element can be used to restore the assembly.

[0020] In a preferred first variant, the adapter element with its bearing opening is arranged on the support element in such a way that the further bearing opening is aligned with the bearing opening of the adapter element.

[0021] In a preferred second embodiment, the adapter element with its bearing opening is arranged on the support element such that the bearing opening of the adapter element is spaced apart from the other bearing opening. In this second embodiment, the bearing opening of the adapter element is preferably spaced apart from the other bearing opening such that the central axis of the bearing opening of the adapter element is parallel to, but spaced apart from, the central axis of the other bearing opening. Preferably, there is no overlap of the two bearing openings when viewed along the central axis. However, the adapter element can be designed such that the other bearing opening is completely or partially closed by the adapter element. Preferably, the locking structure of the bolt element differs from the locking structure of the other bearing opening, such that no engagement is possible between the bolt element and the other locking structure.

[0022] This different design has the advantage that a previously used bolt element cannot be reused when the adapter element is installed. This allows a bolt element with a new locking structure geometry to be inserted between the bearing opening and the shaft. Furthermore, it prevents the reinstallation of a bolt element that is already defective or has been in use for some time during maintenance.

[0023] Preferably, the support element has a through-opening which is laterally bounded by frame sections, wherein the adapter element can be positioned such that said at least one bearing opening of the adapter element is located at a distance from the frame sections between the frame sections. Preferably, the adapter element projects laterally into the through-opening.

[0024] Preferably, the distance mentioned is at most 20%, in particular at most 15% or at most 10%, of the distance between two frame sections opposite each other with respect to the passage opening.

[0025] Preferably, the at least one bearing opening of the adapter element is located in a surface area that extends parallel to the shorter frame sections and from the shorter frame sections into the passage opening by a maximum of 20%, in particular by a maximum of 15% or a maximum of 10%, of the distance between two frame sections opposite each other with respect to the passage opening.

[0026] Preferably, a flange section projecting into the through-opening is arranged on each of two frame sections opposite each other with respect to the through-opening, with the further bearing opening being arranged on the flange section. Preferably, the adapter element is connected to the flange section.

[0027] Preferably, the locking structure of the bearing opening is an internal thread and the locking structure of the shaft is an external thread.

[0028] 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.

[0029] 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.

[0030] In an assembly position, the bolt element is oriented towards the bearing 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 bearing opening in the direction of the central axis.

[0031] In an engagement position of the bolt element, the at least one external thread segment engages with the at least one internal thread segment.

[0032] During assembly, the bolt element with its shaft is inserted through the mounting opening, and the shaft can be slid into the bearing 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 locked position, the two threads are engaged. The shaft's sliding mechanism 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.

[0033] 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.

[0034] 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 engagement position, a pivoting movement around the central axis of the shank. This pivoting movement engages the aforementioned threaded segments.

[0035] Preferably, the at least one external thread segment and the at least one externally threadless groove segment are designed asymmetrically to each other. Preferably, the at least one internal thread segment and the at least one internally threadless groove segment 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 bearing opening in a single, determined orientation.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] This design ensures that when the shaft with the external thread protrudes into the bearing 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.

[0042] Preferably, when pivoting from the mounting position, starting from the aforementioned determined orientation into the engagement 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.

[0043] 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 larger 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.

[0044] Alternatively, the external thread and the internal thread are designed as metric threads.

[0045] Preferably, an outer transition between the side surfaces of the external thread segment, which face 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, which face the groove segment, and the base surface of the groove segment is formed with a concave curve.

[0046] 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. 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 particularly preferred.

[0047] The bearing arrangement according to claim 15 solves the problem of providing a bearing arrangement for mounting an actuating unit that is easier to install. However, the bearing arrangement according to claim 15 can also solve other problems. The bearing arrangement for mounting an actuating unit in front of a cistern comprises a mounting arrangement as described above and a bearing frame with a bearing structure for mounting an actuating unit and at least one mounting opening. The bolt element further comprises a bearing section arranged on the shaft and an actuating tab. Starting from the mounting position, the bolt element can be moved through the engagement position into a locking position in which the bearing section lies in the mounting opening and the actuating tab rests against the bearing frame with a stop surface.

[0048] The arrangement of the preferred thread segments described above 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. When installed, 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.

[0049] 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.

[0050] The bearing structure for the actuating unit can be provided, for example, by cutouts or undercuts in the bearing frame. Preferably, the mounting opening has a cross-sectional shape that is complementary to the cross-sectional shape of the shaft with the at least one externally threaded segment and the at least one groove segment without external threads.

[0051] 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 bearing opening when viewed along its respective central axis.

[0052] This ensures that the bolt element is already in the specified determined position when the bolt element is inserted.

[0053] Preferably, the cross-sectional shape of the mounting opening, viewed in the direction of its central axis, is the same as the cross-sectional shape of the bearing opening, viewed in the direction of its central axis.

[0054] 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.

[0055] Preferably, the said stop surface rests against a front surface of the bearing frame.

[0056] 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.

[0057] In the assembled state, the shaft section experiences a tensile load from the support element to 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. Further optional features of the bearing arrangement are described below:

[0058] 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.

[0059] The actuating tab preferably projects 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] Further embodiments are specified in the dependent claims.

[0080] DESCRIPTION OF PREFERRED EXECUTION FORMS

[0081] The figures show a mounting arrangement 50 for a storage arrangement 1 for the storage of an actuating unit in front of a cistern or a storage arrangement 1 for the storage of an actuating unit in front of a cistern.

[0082] Figures 1a to 2 show the mounting arrangement 50. The mounting arrangement 50 is specifically designed for a bearing arrangement 1 for mounting an actuating unit in front of a cistern. The mounting arrangement comprises a support element 2, which is positioned in the installation position in front of a cistern, and at least one bolt element 8 with a shaft 9 extending along a central axis M. The mounting arrangement 50 further comprises at least one adapter element 51. The adapter element 51 has a connecting section 52 for firmly connecting the adapter element 51 to the support element 2 and a bearing opening 53. The bearing opening 53 and the shaft 9 each have a locking structure 4, 10. The locking structures 4, 10 are designed such that, in a locking position, the bolt element 8 can be secured to the adapter element 51 via the locking structures 4, 10.

[0083] In Figures 1a / 1b, the adapter element 51 is shown separately from the support element 2. Figure 2 shows the adapter element 51 in its assembled state. In the assembled state, the adapter element 51 is firmly connected to the support element 2. In other words, the adapter element 51 is designed separately from the support element 2 and can be connected to it.

[0084] The connecting section 52 has two spaced-apart side walls 54. As can be seen in Figure 1b, the two side walls 54 define a receiving space 55. The support element 2 has at least one flange section 32. In the assembled state, the at least one flange section 32 projects between the side walls 54 into the receiving space 55. The projection of the flange section 32 is shown in Figure 2.

[0085] In the illustrated embodiment, the support element 2 has two flange sections 32, which are arranged opposite each other with respect to a through-opening 30 in the support element 2. An adapter element 51 is arranged on each of the flange sections 32. That is to say, two adapter elements 51 are arranged.

[0086] Figure 1b shows that the bearing opening 53 extends through one of the two side walls 54 and that the other of the two side walls 54 has an opening 56. The bearing opening 53 and the opening 56 are arranged relative to each other such that the shaft 9 can be guided through both the bearing opening 53 and the opening 56. The bearing opening 53 and the opening 56 are aligned with each other. Preferably, the aforementioned locking structure 4 is arranged only at the bearing opening 53. The opening 56 does not have a locking structure 4. The diameter of the opening 56 is preferably selected such that the shaft 9 can be guided through the opening 56 with sufficient clearance.

[0087] In the illustrated embodiment, the side wall 54 in which the bearing opening 53 is arranged has a greater thickness than the side wall 54 in which the opening 56 is arranged. Consequently, the side wall with which the bolt element engages in the snap connection is formed with a greater material thickness than the side wall through which the bolt element simply extends.

[0088] The adapter element 51 has at least one locking lug 57, and the support element 2 has at least one locking recess 58. The sectional views in Figures 3, 4a, and 4b further show that the adapter element 51 locks into place with the locking lug 57, which engages in a locking recess 58 on the support element 2. In the embodiment shown, two locking lugs 57 and two locking recesses 58 are arranged.

[0089] The aforementioned at least one locking lug 57 is arranged on a spring leg 59, in particular by integral part thereof. Two spring legs 59 are arranged here, with one of the aforementioned side walls 54 located between the two spring legs 59. Preferably, the locking lug 57 is positioned on the spring leg 59 such that it faces the aforementioned receiving space 55.

[0090] Figures 1 to 4b further show that the support element 2 has at least one additional bearing opening 3 with a further locking structure 60. This additional bearing opening 3 with the further locking structure 60 can be designed to accommodate a further bolt element not shown in the figures. In the embodiment shown, the locking structure 10 of the bolt element 8 differs from the further locking structure 60 of the additional bearing opening 3, such that no engagement is possible between the bolt element 8 and the further locking structure 10.

[0091] In Figures 1 to 4b, adapter element 51 with its bearing opening 53 is arranged on the support element 2 such that the further bearing opening 3 is aligned with the bearing opening 53 of the adapter element 51. An alternative is shown in Figures 5a and 5b. Here, the adapter element 51 with its bearing opening 53 is arranged on the support element 2 such that the bearing opening 53 of the adapter element 51 is spaced apart from the further bearing opening 3. In these three variants, the adapter elements 51 are designed differently from one another such that the bearing opening 53 is located in different positions. In other embodiments, a variant of the adapter element 51 may be provided which can be connected to the support element 2 at different positions.

[0092] As mentioned above, the support element 2 has a through-opening 30. The through-opening 30 is laterally bounded by lateral frame sections 31. The aforementioned flange section 32 projects from the lateral frame sections 31 into the through-opening 30.

[0093] The adapter element 51 is preferably positionable such that the aforementioned at least one bearing opening 53 of the adapter element 51 is located at a distance A from the frame sections 31 between the frame sections 31. The distance A is shown in Figure 2.

[0094] Preferably, the distance A is at most 20%, in particular at most 15% or at most 10%, from the distance B between two frame sections 31 opposite each other with respect to the passage opening 30. The distance B is shown in Figure 1a.

[0095] The at least one bearing opening 53 of the adapter element 51 is particularly preferably arranged in a surface area C. Surface area C is schematically represented by a dashed line in Figure 2. Surface area C extends parallel to the shorter frame sections 31 and from the shorter frame sections 31 by a maximum of 20%, in particular by a maximum of 15% or a maximum of 10%, of the distance B between two frame sections 31 opposite each other with respect to the passage opening 30 into the passage opening 30. The at least one bearing opening 53 can be positioned at any point in this surface area C.

[0096] With reference to all figures, a preferred form of the detent structure will now be described in more detail. Preferably, the detent structure of the bearing opening 53 is an internal thread and the detent structure of the shaft 9 is preferably an external thread.

[0097] 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.

[0098] 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.

[0099] In Figures 2, 6, and 7a, the at least one bolt element 8 is shown in an assembly position. In this position, the bolt element 8 is oriented towards the bearing opening 53 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 bearing opening 53 in the direction of the central axis M. In Figure 6a, 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.

[0100] Starting from the mounting position, the bolt element 8 can be pivoted about its central axis M into the engagement position and / or the locking position. The pivoting movement is illustrated by arrows S in Figure 7a. The locking position is shown in Figure 7b; when pivoting from the mounting position to the locking position, the bolt element 8 is pivoted by an angle in the range of 90° to 180°. In the embodiment shown in the figures, the angle is 180°.

[0101] During movement into the locking position, the external thread and the internal thread are brought into common engagement. In the locking position of the bolt element 8, the at least one external thread segment 14 engages with the at least one internal thread segment 17.

[0102] Based on Figures 6, 7a and 7b, a preferred arrangement of thread segments is now shown.

[0103] 14, 17 and the groove segments 15, 18 are explained.

[0104] 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 bearing opening 53 exclusively in a single determined orientation.

[0105] This asymmetrical design can be clearly seen in Figure 3. The bearing opening 53 is shown on the left side of Figure 3, and the external thread 10 is shown on the right side of the figure.

[0106] 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.

[0107] 15. The arc angles in Figure 3 bear the reference numerals a14-1 , a14-2 and a14-3 for the external thread segments 14 and a15-1 , a15-2 and a15-3 for the non-external threaded groove segments 15.

[0108] 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 externally threadless groove segments 15 are each of different sizes. This achieves the aforementioned asymmetrical arrangement.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] As mentioned, the figures also show a bearing arrangement 1 according to a preferred embodiment. The bearing arrangement 1 comprises a support element 2, a bearing frame 5, and at least one bolt element 8. Here, two bolt elements 8 are arranged. 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 on the front surface of the partition wall. When the at least one bolt element 2 is actuated, the bearing frame 5 is clamped onto 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.

[0113] 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.

[0114] In the illustrated embodiment, the at least one bolt element 8 comprises the shaft 9 extending along a central axis M, which has the 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.

[0115] Furthermore, as can be seen from Figure 3, the bearing section 10 lies in the mounting opening 7 and the actuating tab 11 rests against the bearing frame 5 with a stop surface 12. Here, the stop surface 12 rests against a front surface 35 on the bearing frame 5.

[0116] 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 3.Typically, the aforementioned partition wall is located in the space Z between the bearing frame 5 and the support element 2.

[0117] Figures 1a / 1b further show that the mounting 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 externally threadless groove segment 15. The cross-sectional shape of the mounting opening 7, viewed along its central axis, is the same as the cross-sectional shape of the bearing opening 53, viewed along its central axis.

[0118] 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.

[0119] Figures 4a / 4b show 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.

[0120] Preferably, the cross-sectional shape of the thread flanks 26, 27 of the external thread 10 and the internal thread 4 is asymmetrical. 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 variant, the thread flank 26, which is oriented towards the support element 2, is at a larger angle to the central axis M than the thread flank 27, which is oriented towards the bearing frame 5. Due to the asymmetrical design, tensile forces applied to the shaft in the direction of the central axis from the support element 2 to the bearing frame 5 can be transferred more effectively from the external thread to the internal thread.

[0121] In the embodiment shown, the bearing frame 5 has a through opening 33, which is laterally limited by frame sections 34, wherein the fastening opening 7 is arranged on two frame sections 34 opposite the through opening 33.
