MOUNTING DEVICE FOR A SANITARY ITEM

Description

TECHNICAL FIELD

[0001] The present invention relates to a mounting device for a sanitary article according to claim 1. STATE OF THE ART

[0002] Wall brackets for a mounting frame for sanitary appliances are known from publications EP 0 786 562 and EP1 260 639. The mounting frame is connected to the wall bracket with a screw. The screw is mounted on the mounting frame via a bearing element inserted into a cavity in a support of the mounting frame.

[0003] The bearing components are mounted in the cavity of the mounting frame via locking elements. In practice, it has also been found that the dimensions of the support cavities can vary considerably, particularly with coated surfaces. Due to this dimensional variation, the bearing components are designed to always have sufficient clearance. This offers the advantage of simple assembly, but the disadvantage of a fit that always results in interference.

[0004] Further mounting devices for sanitary articles have become known from the publications EP 3 369 945, EP 2 752 526 and EP 1 665 418. PRESENTATION OF THE INVENTION

[0005] Based on this prior art, the invention is based on the object of providing a mounting device for a sanitary article that overcomes the disadvantages of the prior art. In particular, it is an object of the present invention to provide a mounting device for a sanitary article that provides a fixed mounting for a screw. A particularly preferred object is that a fixed mounting for a screw can be provided despite the large dimensional tolerance of a support element in which the screw is mounted.

[0006] This object is achieved by the subject matter according to claim 1. Accordingly, a mounting device for fastening at least one sanitary article comprises at least one support, a screw, and a bearing element with which the screw is mounted relative to the support. The at least one support comprises a support wall which delimits a cavity, a first opening, and a second opening. The openings are arranged in the support wall and lie opposite one another with respect to the cavity. The openings penetrate the support wall. The support provides a first support-side stop surface at the first opening and a second support-side stop surface at the second opening. The screw has a threaded portion and a screw head. The bearing element has a receiving space for supporting the screw. The receiving space extends along a central axis.The bearing element has at least one first bearing-element-side stop surface, which is in contact with the first support-side stop surface in the assembled state. Furthermore, the bearing element has at least one second bearing-element-side stop surface, which is in contact with the second support-side stop surface in the assembled state. The at least one second bearing-element-side stop surface is arranged on at least one spring tab, wherein the at least one spring tab and the second bearing-element-side stop surface are arranged such that the bearing element is clamped between the two support-side stop surfaces without play.

[0007] In other words, the bearing element is clamped between the two support-side stop surfaces. Arranging the bearing element-side stop surface on a spring plate has the advantage of compensating for manufacturing tolerances in the support. Such manufacturing tolerances can cause the distance between the two support-side stop surfaces to vary from support to support.

[0008] Furthermore, clamping the bearing element in the cavity provides the installer with a mounting device that is easier to handle. In particular, positioning the screw for a wall anchor is easier because the screw is firmly seated in the support.

[0009] Preferably, the first support-side stop surface is provided by a wall surface of the support wall facing the cavity at the first opening. The second support-side stop surface is provided by the edge of the second opening and / or by a wall surface of the support wall facing the cavity at the second opening.

[0010] Preferably, several of said spring tabs are arranged. The spring tabs are preferably arranged at regular intervals around the circumference of the side wall.

[0011] Preferably, the column wall extends substantially completely around the column axis in cross-section. The column axis runs longitudinally through the center of the cavity.

[0012] In a preferred embodiment, the mounting device can comprise two spaced-apart supports connected to at least one cross member or crossbeam. In such an embodiment, the sanitary article is preferably mounted on the cross member or crossbeam.

[0013] Preferably, the second bearing element-side stop surface is designed such that the distance between the first bearing element-side stop surface and the second bearing element-side stop surface is different depending on the position of the spring tab.

[0014] This allows the clamping in question to be achieved particularly well, regardless of the clear width between the two support-side stop surfaces.

[0015] Preferably, the second bearing element-side stop surface is designed such that the distance between the first bearing element-side stop surface and the second bearing element-side stop surface is smaller during a deflection towards the central axis than as the distance away from the central axis increases.

[0016] Preferably, the second bearing element-side stop surface is curved with a curvature, or the second bearing element-side stop surface is inclined at an angle to the central axis.

[0017] The curvature as well as the angled design have the advantage that a very simple structure can be created for tolerance compensation or for backlash-free clamping.

[0018] Preferably, the curvature is curved around a curvature axis, wherein the curvature axis is spaced apart and runs transversely to the central axis. The curvature is preferably selected such that when the curvature abuts the support-side stop surface, the angle of the tangent at the contact point is substantially the same for all support dimensions. This means that the second bearing-element-side stop surface abuts the support-side stop surface at the same angle in every position of the spring tab.

[0019] Preferably, the second bearing-element-side stop surface has a step that divides the second bearing-element-side stop surface into two surface sections. This step has the particular advantage that the bearing element can be used with different support dimensions, for example, with supports with different wall thicknesses.

[0020] Preferably, the at least one spring tab extends at an angle α to the central axis. The angle α is preferably in the range of 3° to 35°.

[0021] The spring tab runs at an angle to the central axis, especially when assembled. When the bearing element is inserted into the two openings and the cavity, at least one spring tab is pivoted toward the central axis.

[0022] Preferably, the bearing element further comprises at least one locking tab on which a locking cam is formed, wherein the locking cam engages in a groove arranged on the screw.

[0023] The locking tab is preferably formed by two slots which extend in the direction of the central axis through the side wall mentioned below.

[0024] Preferably, the first bearing element-side stop surface is provided by a shoulder located on the side wall mentioned below or on the outer side wall mentioned below.

[0025] Preferably, a guide section with a cylindrical guide surface extends from the first stop surface. The guide section projects into the first opening.

[0026] Preferably, the spring tabs mentioned are formed identically to each other with the second bearing element-side stop surface.

[0027] Preferably, the bearing element has at least one further spring tab having a further stop surface. The further stop surface can be brought into contact with the second support-side stop surface and can provide a further stop in the event of a mechanical failure of the contact between the second bearing-element-side stop surface and the second support-side stop surface.

[0028] Preferably, the additional stop surface is offset from the second bearing-element-side stop surface in the direction of the central axis and, in particular, is spaced closer to the first bearing-element-side stop surface than the second bearing-element-side stop surface. In the assembled state, the additional stop surface is thus spaced from the second support-side stop surface.

[0029] Preferably, the further stop surface is oriented substantially at right angles to the central axis when viewed in cross section through the central axis.

[0030] Preferably, the at least one further spring tab has a bearing surface which adjoins the stop surface, wherein the bearing surface is in contact with the inside of the opening in the assembled state.

[0031] Preferably, four of said further spring tabs are arranged, wherein the four spring tabs are preferably arranged at a uniform distance from one another.

[0032] Preferably, a plurality of the further spring tabs are arranged, wherein preferably two mutually opposite further spring tabs form a first pair and wherein two mutually opposite further spring tabs form a second pair, wherein the width of the spring tabs of the first pair is equal to the width of the spring tabs of the second pair, or wherein the width of the spring tabs of the first pair is not equal to the width of the spring tabs of the second pair.

[0033] Preferably, at least two of said further spring tabs have a different width.

[0034] Preferably, at least one spring tab with the second bearing element-side stop surface is located between two of the further spring tabs; in particular, at least two spring tabs are located between two of the further spring tabs.

[0035] Preferably, the spring tabs and the other spring tabs each have the same length.

[0036] Preferably, the additional spring tabs are also formed on the side wall via a tab section.

[0037] The bearing element is preferably made of a plastic, such as polybutylene terephthalate (PBT) or polyamine (PA). The supports are preferably made of steel and have a rectangular or square cross-sectional shape.

[0038] The bearing element can be made in one piece or in two pieces.

[0039] If the bearing element is provided in one piece, the receiving space is limited by a side wall.

[0040] Preferably, the spring tab is connected to the side wall via a first tab section which extends at an angle from the outside of the side wall.

[0041] Preferably, the side wall has a support surface for the screw head of the screw, wherein the support surface is arranged offset from the second bearing element-side stop surface, wherein the offset is such that the screw head lies substantially completely or entirely between the support surface and the second bearing element-side stop surface.

[0042] In other words, the screw head is positioned in the offset area and is thus radially enclosed on the outside by the bearing element. The screw head does not protrude further on the side of the second bearing element-side stop surface, but is recessed in the offset area. The spring tabs extend beyond the support surface, as seen from the side wall.

[0043] If the at least one bearing element is formed in two pieces, it is formed with an inner bearing element part and an outer bearing element part. The inner bearing element part is displaceably mounted in the outer bearing element part. The inner bearing element part has the receiving space in which the screw is received. The outer bearing element part has the at least one first bearing-element-side stop surface and the at least one second bearing-element-side stop surface.

[0044] Preferably, the inner bearing element part is displaceable relative to the outer bearing element part from an initial position into an assembly position, wherein the inner bearing element part is latched to the outer bearing element part in the initial position via a first latching connection, wherein during the assembly process the first latching connection is released and the inner bearing element part is displaceable relative to the outer bearing element part into the assembly position, and wherein in the assembly position the inner bearing element part is latched to the outer bearing element part via a second latching connection.

[0045] Preferably, the inner bearing element part has at least one surface that presses the at least one spring tab outward when the inner bearing element part is in the assembled position. Preferably, the at least one spring tab is pressed radially outward.

[0046] Preferably, the receiving space in the inner bearing element part is delimited by a side wall, wherein the side wall has a support surface for the screw head of the screw, wherein the support surface is arranged offset from the second bearing element-side stop surface, wherein the offset is such that the screw head comes to lie substantially completely or entirely between the support surface and the second bearing element-side stop surface.

[0047] Preferably, the outer bearing element part has an outer side wall from which the at least one spring tab protrudes, and the first bearing element-side stop surface is provided by a shoulder located on the outer side wall.

[0048] Preferably, the above-mentioned further spring tab in the two-part embodiment extends away from the outer side wall of the outer bearing element part.

[0049] Further embodiments are specified in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF PREFERRED EMBODIMENTS

[0051] The figures show a section or part of a mounting device 1 for fastening at least one sanitary article. The sanitary article is, for example, a washbasin, a toilet bowl, a urinal, a cistern, etc. Figures 1 to 8 is a first embodiment and in the Figures 9 to 13c A second embodiment of the present invention is shown. Identical parts are provided with identical reference numerals.

[0052] The mounting device 1 comprises at least one support 2, at least one screw 10, and at least one bearing element 13, via which the screw 10 is mounted in the support 2. The support 2 can be connected to another support 2 by at least one cross member. The support 2 or the at least one cross member can have fastening points for attaching the at least one sanitary article. One bearing element 13 and thus one screw 10 can be arranged per support 2. However, it is also conceivable for several bearing elements 13 and thus several screws 10 to be arranged per support 2.

[0053] The support 2 has a support wall 3. The support wall 3 delimits a cavity 4. A first opening 5 and a second opening 6 extend through the support wall 3. The first opening 5 is arranged opposite the second opening 6 with respect to the cavity 4. The wall surface 7 of the support wall 3 facing the cavity 4 at the first opening 5 provides a first support-side stop surface 8. The wall surface 7 of the support wall 3 facing the cavity 4 at the second opening 6 and / or the edge of the second opening 6 towards the cavity provide a second support-side stop surface 9. The bearing element 13 can abut against these stop surfaces 8, 9 when installed.

[0054] The screw 10 comprises a threaded portion 11 and a screw head 12. The threaded portion 11 engages in an anchor element fastened to a supporting structure, which is not shown in the figures, and is thus secured to the supporting structure.

[0055] In the first embodiment, the bearing element 13 is formed in one piece. In the second embodiment, the bearing element 13 is formed in multiple parts with an inner bearing element part 31 and an outer bearing element part 32. The bearing element 13 has a receiving space 15. The screw 10 is mounted in the receiving space 15. The bearing element 13 has at least one first bearing-element-side stop surface 16. In the assembled state, i.e., when the bearing element 13 is connected to the support 2, the first bearing-element-side stop surface 16 is in contact with the first support-side stop surface 9. Furthermore, the bearing element 13 has at least one second bearing-element-side stop surface 17. In the assembled state, the second bearing-element-side stop surface 17 is in contact with the second support-side stop surface 9.

[0056] The at least one second bearing-element-side stop surface 17 is arranged on at least one spring tab 18. The at least one spring tab 18 and the second bearing-element-side stop surface 17 are arranged such that the bearing element 13 is clamped without play between the two support-side stop surfaces 8, 9. The elasticity of the spring tab 18 allows the aforementioned clamping effect to be achieved.

[0057] In other words, the bearing element 13 is clamped between the two support-side stop surfaces 8, 9. The spring tab 18, on which the stop surface 17 is arranged, allows compensation for the dimensional tolerances of the cavity or the distance between the two stop surfaces 8, 9.

[0058] In the Figures 1 and 2and 9 and 10 show partial perspective views of the mounting device 1. These figures show how the stop surfaces abut one another as described above. In the mounted position, the bearing element 13 is essentially completely mounted in the support 2. The bearing element 13 extends from the first opening 5 to the second opening 6 transversely through the cavity 5. Furthermore, the screw 10 extends through the receiving space 15 and protrudes with the threaded portion 11 from the first opening 5. The screw head 12 is accessible from the second opening 6. The screw 10 is axially fixed and rotatably mounted in the receiving space 15.

[0059] In the Figure 3 a perspective view of the mounting device 1 is shown, wherein the bearing element 13 and the screw 10 are not yet fully assembled.

[0060] In the Figures 4 and 5Detailed views of the bearing element 13 and the screw 10 or of the bearing element 13 in isolation are shown.

[0061] The Figures 6 to 8 show top views of the mounting device 1.

[0062] Further preferred features of the mounting device 1 will now be explained in more detail with reference to all figures.

[0063] The second bearing-element-side stop surface 17 is designed such that the distance between the first bearing-element-side stop surface 16 and the second bearing-element-side stop surface 17 varies depending on the position of the spring tab 18. This ensures that the two bearing-element-side stop surfaces 16, 17 are in contact with the corresponding stop surfaces 8, 9 on the support 2 side, regardless of the dimensional tolerance deviation of the supports 2.

[0064] In the embodiment shown, the second bearing-element-side stop surface 17 is curved. The curvature extends around a curvature axis that is oriented perpendicularly and spaced from the central axis M. Furthermore, the second bearing-element-side stop surface 17 has a step 19 that divides the second bearing-element-side stop surface 17 into two surface sections.

[0065] In the illustrated embodiment, the at least one spring tab 18 extends at an angle α to the central axis M. During assembly of the bearing element 13, the spring tab 18 deflects toward the central axis M and then, due to its resilient properties, returns from a deflected position toward its original position. During this movement, the second bearing-element-side stop surface 17 comes into contact with the second support-side stop surface 9.

[0066] In the embodiment shown, several spring tabs 18 are arranged. The spring tabs 18 are designed identically to one another. The spring tabs 18 are arranged distributed around the circumference of a side wall 14 of the bearing element 11. The spring tabs 18 are connected to the side wall 14 via a tab section 20, which runs from the outer side 21 of the side wall 14 at an angle. The tab section 20 here runs essentially at right angles to the central axis M and the bearing element 13 has at least one further spring tab 27, which is arranged in addition to the at least one spring tab 18 with the second bearing element-side stop surface 17. This further spring tab 27 is Figures 4, 5 and 8shown. The further spring tab 27 has a further stop surface 28. The further stop surface 28 is arranged offset from the second bearing element-side stop surface 17 in the direction of the central axis M. In particular, the further stop surface 28 is at a smaller distance from the first bearing element-side stop surface 16 than the second bearing element-side stop surface 16. The at least one further spring tab 27 further has a bearing surface 29 which adjoins the stop surface 28, wherein the bearing surface is in contact with the inside of the second opening 6 in the assembled state.

[0067] In the embodiment shown, a guide section 30 extends away from the side wall 14 opposite the spring tab 18. The guide section 30 adjoins the first bearing-element-side stop surface 16. The guide section 30 comes into contact with the inner surface of the first opening 5. The guide section 30 has a cylindrical shape. A shoulder 26 extends from the guide section 30, which provides the first bearing-element-side stop surface 16.

[0068] Furthermore, the side wall 14 has a support surface 22 for the screw head 12 of the screw 10 opposite the bearing surface 29. The support surface 22 is offset from the second bearing-element-side stop surface 17. This offset creates a space in which the screw head 12 comes to rest. Preferably, the offset is such that the screw head 12 comes to rest essentially entirely between the support surface 22 and the second bearing-element-side stop surface 17. This means that the screw head 12 lies essentially entirely within said space.

[0069] Furthermore, the bearing element 13 has a locking tab 23, onto which a locking cam 24 is formed. The locking cam 24 engages in a groove 25 arranged on the screw 10. The connection between the locking cam 24 and the groove 25 secures the screw 10 axially in the receiving space 15. The screw 10 is arranged so that it can rotate accordingly in the receiving space 15.

[0070] In the embodiment shown, four of the aforementioned additional spring tabs 27 are arranged, with the four spring tabs 27 preferably being arranged at a uniform distance from one another. Two opposing additional spring tabs 27 form a first pair, and two opposing additional spring tabs 27 form a second pair. The width of the spring tabs 27 of the first pair is different from the width of the spring tabs 27 of the other pair.

[0071] In the embodiment shown, at least one spring tab 18 with the second bearing element-side stop surface 17 lies between two of the further spring tabs 27. Here, two spring tabs 17 lie between two of the further spring tabs 27.

[0072] According to the first embodiment according to the Figures 1 to 8 The bearing element 11 is formed in one piece. The bearing element has a side wall 14 extending around a central axis M. The side wall 14 defines the receiving space 15.

[0073] According to the second embodiment, the bearing element 13 is formed in two parts. The bearing element 13 comprises an inner bearing element part 31 and an outer bearing element part 32. The two bearing element parts 31 and 32 are Figures 11a and 11b presented in more detail. The Figures 12a to 12c and 13a to 13c show sectional views. The inner bearing element part 31 is slidably mounted in the outer bearing element part 32.

[0074] The inner bearing element part 31 has the receiving space 15 in which the screw 10 is mounted. The outer bearing element part 32 has at least one first bearing element-side stop surface 16 and at least one second bearing element-side stop surface 17.

[0075] The inner bearing element part 31 can be moved from an initial position to an assembly position. In the initial position, the inner bearing element part 31 is locked to the outer bearing element part 32 via a first locking connection 33. The first locking connection is provided by a locking cam 39 and a locking recess 40 into which the locking cam 39 engages.

[0076] During the assembly process, the first locking connection 32 is released and the inner bearing element part 31 is moved into the assembly position relative to the outer bearing element part 32.

[0077] In the assembly position, the inner bearing element part 31 is locked to the outer bearing element part 32 via a second locking connection 34. The second locking connection 34 is, as shown in the Figures 13a to 13c shown, provided by two oppositely arranged locking lugs 41.

[0078] The receiving space 15 in the inner bearing element part 31 is delimited by a side wall 14. The side wall 14 has a bearing surface 22 for the screw head 12 of the screw 10. The bearing surface 22 is offset from the second bearing element-side stop surface 17, wherein the offset is such that the screw head 12 lies essentially completely or entirely between the bearing surface 22 and the second bearing element-side stop surface 17. Opposite the bearing surface 22, the inner bearing element part 31 has a bearing surface 36. When the inner bearing element part 31 is in the assembled position, the bearing surface 36 rests on a corresponding bearing surface 37 on the outer bearing element part 32.

[0079] Furthermore, the outer bearing element part 32 has an outer side wall 38. The at least one spring tab 18 protrudes from the outer side wall. In the embodiment shown, the optional at least one further spring tab 27 with the further stop surface 28 is also arranged protruding from the outer side wall. The first bearing element-side stop surface 16 is provided by a shoulder 26 located on the outer side wall 14. Furthermore, the outer side wall 38 also comprises the first bearing element-side stop surface 16.

[0080] In the preferred embodiment, the inner bearing element part 32 has at least one surface 35, which presses the at least one spring tab 18 radially outward when the inner bearing element part 32 is in the assembly position. If the inner bearing element part 32 is moved to the starting position, the surface 35 comes to lie in an area where the at least one spring tab 18 is no longer blocked. The surface 35 is in the Figure 13c shown. Here, surface 35 is part of the locking cam 39. If the additional spring tab 27 is present, it is also conceivable that another surface 35 acts on the additional spring tab 27.

[0081] As in the first embodiment, the screw 10 is also held in the receiving space by a locking cam 24.

[0082] When disassembling the assembly device according to the second embodiment, the inner bearing element part 32 must be moved from the assembly position to the starting position.

[0083] Preferably, the inner bearing element part 31 is mounted in the outer bearing element part 32 in a rotationally fixed and axially displaceable manner.
