Description

TECHNICAL FROZEN

[0001] The present invention relates to a mounting device for fastening at least one sanitary article according to the preamble of claim 1. STATE OF THE ART

[0002] Mounting devices for securing sanitary ware are known from the prior art. Such mounting devices are permanently installed behind a false wall and serve to store sanitary ware, such as cisterns, toilet bowls, urinals, fittings, wash basins, control elements, electrical components, etc. For example, EP 2 662 502 discloses such a mounting device.

[0003] From EP 3 071 757, a further mounting device has become known which has a support element that supports the cross member.

[0004] From EP 3 149 251, a further mounting device has become known in which a support is connected to a hollow body which, on the one hand, has a supporting effect for the support and, on the other hand, provides a support surface for the sanitary body fastened to the support.

[0005] Although state-of-the-art mounting devices achieve excellent results when installed in a building, manufacturers are keen to simplify production. Many of the existing mounting devices are very complex to manufacture. PRESENTATION OF THE INVENTION

[0006] Based on this prior art, the invention is based on the object of providing a mounting device for fastening at least one 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 fastening at least one sanitary article that is simpler and more efficient to manufacture. This is particularly true while ensuring high stability for the mounting device.

[0007] This object is achieved by a mounting device for fastening at least one sanitary article according to claim 1. Accordingly, the mounting device comprises two supports which are spaced apart from one another and each extend along a central axis, and a cross member element which is arranged between the supports and connects the two supports and has at least one fastening element. The cross member element is provided by a front support part with a support wall on which a sanitary article can be supported, and by a rear support part with a rear wall. The front support part and / or the rear support part have at least one connecting tab which projects at an angle, in particular at a right angle, from the support wall and / or from the rear wall. The two support parts can be firmly connected to one another via the at least one connecting tab such that, in the connected state, the support wall is spaced apart from the rear wall.

[0008] The arrangement of connecting tabs on the two support parts has the advantage of making the truss element very easy to manufacture. In particular, complex alignment work is eliminated, as the connecting tabs allow the two support parts to be positioned relative to each other and then connected to each other via the connecting tabs.

[0009] The term "permanently connectable" refers to a connection that is mechanically strong. Such a connection can be achieved through a material-to-material and / or form-fitting and / or friction-locking connection. The connection is particularly preferably a welded connection.

[0010] The distance between the supporting wall and the rear wall has the advantage that the truss element can be provided as a hollow body, which creates a high level of mechanical stability.

[0011] The at least one fastening element can be designed in various ways. For example, as a threaded opening directly in the truss element, as openings in the truss element, as nuts behind an opening in the truss element, or as a separate fastening part behind an opening in the truss element. Preferably, a threaded rod can be connected to the at least one fastening element. This means that the at least one fastening element is, for example, a receptacle for a threaded rod. Preferably, said fastening part is firmly connected to the truss element and is preferably located behind the front web.

[0012] Preferably, the at least one connecting tab of the front support part lies in surface contact with the at least one connecting tab of the rear support part. In the connected state, the connecting tabs of the front support part and the rear support part are in surface contact with each other.

[0013] The flat contact between the two connecting tabs provides the advantage of precise positioning of the two support parts relative to each other. Furthermore, the flat contact creates a supporting effect between the two support parts. Furthermore, the fixed connection can be placed in the area of the flat contact.

[0014] Preferably, in one variant, the at least one connecting link of one support part is shorter than the at least one connecting link of the other support part. At least one weld is provided at the front end of the shorter connecting link and the surface of the longer connecting link. The shorter design of one connecting link creates space for a weld. In particular, the weld is located in the area of the surface of the longer connecting link, which has the advantage that the weld is located in a location that is well suited for a weld.

[0015] In another variant, the at least one connecting tab of one support part is preferably of the same length as the at least one connecting tab of the other support part. At least one weld is provided at the front end of one connecting tab and the surface of the other connecting tab. If the connecting tabs are of the same length, the welded joint also lies on the surface of the other connecting tab.

[0016] Preferably, the support wall, the rear wall, the connecting straps and the supports define a hollow body with a cavity, wherein the said welding point is located outside the cavity.

[0017] This creates good accessibility for the weld. In particular, the shorter connecting plate is located outside the cavity when connected.

[0018] Preferably, the at least one connecting tab of the front support part abuts the inner surface of the rear support part facing the front support part, thereby defining the distance between the front support part and the rear support part. Alternatively or equally, the at least one connecting tab of the rear support part abuts the inner surface of the front support part facing the rear support part, thereby defining the distance between the front support part and the rear support part.

[0019] By attaching the connecting straps to the corresponding inner surface, there is the advantage of eliminating the need for additional elements to define the distance between the two support parts. This greatly simplifies the manufacture and assembly of the truss element.

[0020] Preferably, the front support part is formed integrally with the support wall and the at least one connecting tab. Likewise, the rear support part is formed integrally with the rear wall and connecting tab.

[0021] Preferably, the two support parts are made from a single sheet metal, with the connecting tabs being bent from the support wall or rear wall. Before the bending process, the sheet metal is cut or punched to the required shape and dimensions.

[0022] Preferably, the truss element comprises a recess which provides a free space through the truss element through which a drain pipe can be passed, wherein the recess in the support parts is formed by a cutout in the support wall and the rear wall.

[0023] Preferably, the recess extends from below into the truss element and is open at the bottom. The recess can have various shapes. Particularly preferably, the recess is rectangular. Other shapes, such as V-shaped or trapezoidal, are also conceivable. Particularly preferably, the recess has straight side edges so that a connecting tab can be bent away from the supporting wall or the rear wall.

[0024] Preferably, connecting tabs extend along the side edges opposite the cutout and further connecting tabs extend along the side edges which extend from the cutout to the support.

[0025] Preferably, the connecting tabs extend over the entire length of the respective side edge from which they protrude.

[0026] Preferably, a reinforcement section is attached to the top of the supporting wall and / or the rear wall in the installed position.

[0027] The reinforcement sections have the advantage that the stability of the truss element can be further increased.

[0028] Preferably, the reinforcement section arranged on the supporting wall is designed as a bending tab, which preferably has an optional interruption for the passage of connecting cables. Preferably, the reinforcement section arranged on the rear wall is designed as a bending tab, which preferably extends completely between the cross members.

[0029] The bending tabs preferably have a reinforcing bead at the end. This allows the corresponding section to be mechanically reinforced, particularly against bending stress.

[0030] Preferably, in the connected state, the reinforcing section of the supporting wall is spaced apart from the reinforcing section of the rear wall, so that a space for receiving fastening elements is created between the reinforcing sections.

[0031] Preferably, the supporting wall and the rear wall are connected to the respective support via their side edges facing the support, with the connecting tabs running along free side edges not connected to the support. The connecting tabs are preferably connected to each other via a welded joint. Preferably, the truss element is made of metal and is connected to the support in a materially bonded manner, in particular via a welded joint, and / or in a form-fitting or force-fitting manner. Alternatively, the truss element is made of plastic and is connected to the supports in a form-fitting and / or force-fitting manner.

[0032] Preferably, the support section extends substantially downwards with respect to the at least one fastening element in the installed position.

[0033] Preferably, the maximum extension of the truss element in the direction of the longitudinal axis of the supports is in the range from 150 mm to 500 mm, in particular in the range from 200 mm to 400 mm, particularly preferably the extension is between 275 mm and 350 mm.

[0034] Preferably, the front surfaces of the supports span a front plane and the rear surfaces of the supports span a rear plane, with the truss element lying between these two planes or congruent with these planes

[0035] Preferably, at least one, in particular each, of the supports is connected to a footrest, via which footrest the mounting device stands on a floor, wherein the footrest is preferably designed to be displaceable relative to the support and to be lockable relative to the support.

[0036] A method for producing a mounting device as described above is characterized in that that in a first step the two support parts and the two supports are provided, that in a subsequent step the two support parts are connected to each other via the connecting straps and to the supports.

[0037] Preferably, all welds are made either from the back or the front. This has the advantage of eliminating the need to turn the assembly fixture during production.

[0038] An arrangement comprises a mounting device as described above and a sanitary article mounted on the mounting device with a support surface, wherein the support surface of the sanitary article overlies parts of the support wall of the front support part.

[0039] Further embodiments are specified in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

In the drawings: Fig. 1 is a perspective view of a mounting device according to the present invention from the front; Fig. 2 is a perspective view of the mounting device according to Figure 1 from behind; Fig. 3 a front view of the mounting device according to Figure 1 from the front; Fig. 4 an exploded view of the mounting device according to Figure 1; Fig. 5 an exploded view of a traverse element of the mounting device according to the Figure 1 from the front; Fig. 6 an exploded view of a traverse element of the mounting device according to the Figure 1 from behind; and Fig. 7 a sectional view along the section line VII-VII of the Figure 3 . DESCRIPTION OF PREFERRED EMBODIMENTS

[0041] The figures show a mounting device 1 for attaching at least one sanitary article. In the illustrated embodiment, the mounting device 1 comprises two spaced-apart supports 2, each extending along a central axis M, and a cross member 3 arranged between the supports 2 and connecting the two supports 2, with at least one fastening element 4. The sanitary article is attached and supported to the cross member 3.

[0042] In the embodiment shown, several fastening elements 4 are arranged side by side. These fastening elements 4 can be used to attach a sanitary article to the mounting device 1. In the installed position, the two supports 2 typically extend in a vertical V, i.e., in the perpendicular direction. The two supports 2 are connected at the top with a cross member 28.

[0043] The Figures 1 and 2 show the assembly device in perspective from the front and from the back. Figure 3a view from the front is shown. In the embodiment shown, the traverse element 3 has a recess 18 through which, for example, a drainpipe can be passed. The width of the recess 18, seen transversely to the center axis M of the supports 2, corresponds in the example shown to approximately one third of the total width of the traverse element 3. To the left and right of the recess 18, the traverse element 3 or the front support part 5 and the rear support part 7 extend. In other words, the recess 18 extends from an area below and opposite the at least one fastening element 4 into the traverse element 3. Seen in the installed position, the recess 18 extends from below into the traverse element 3 and is open towards the bottom.

[0044] The Figure 4then shows an exploded view of the mounting device 1. The traverse element 3 is shown here before the actual assembly and connection to the support 2. The traverse element 3 is provided by a front support part 5 with a support wall 6 and by a rear support part 7 with a rear wall 8. The sanitary article can be supported accordingly on the support wall 6. In the embodiment shown, the at least one fastening element 4 lies above the support wall 6 when viewed in the installed position. This means that the at least one fastening element 4 is subjected to tensile stress when the sanitary article is installed, and that the support wall 6 or the traverse element 3 is subjected to compressive stress.

[0045] In the embodiment shown, the front support part 5 and the rear support part 7 have at least one connecting bracket 9, 10. The connecting brackets 9, 10 protrude at right angles from the support wall 6 and the rear wall 8, respectively. However, the angle can also have a different dimension. The two support parts 5, 7 are formed in one piece. This means that the connecting brackets 9, 10 are arranged integrally on the support wall 6 and the rear wall 8, respectively.

[0046] The two support parts 5, 6 can be firmly connected to one another via at least one connecting strap 9, 10. The connection is such that, in the connected state, the support wall 6 is spaced apart from the rear wall 8. The connection is made starting from the Figure 3 shown in such a way that the two support parts 5, 7 are moved towards each other until the two support parts 5, 6 are positioned accordingly and can be connected via the at least one connecting tab 9, 10.

[0047] The Figures 5 and 6 then show exploded views of the truss element 2 without the supports 2. The front support part 5 and the rear support part 7 are shown individually. Figure 7 shows a sectional view along section line VI of the Figure 2 . Based on the Figures 5 to 7 Further features of the two support parts are now explained.

[0048] The front support part 5 has a cutout 19 in the support wall 6 to provide the aforementioned recess 18. The cutout 19 is formed by two opposing side edges 20. A connecting tab 9 protrudes from each of the side edges 20 at a right angle to the support wall 6. On each of the lower side edges 21, which extend from the end of the side edge 20 at the lower end of the front support part 5 to the support 2, a connecting tab 9 is arranged which protrudes at a right angle to the support wall 6. The lower side edge 21 extends essentially horizontally in the installed position. The connecting tabs 9 have a length viewed in the normal direction to the support wall 6. The length of the connecting tabs 9 protruding from the side edge 20 is greater than the length of the connecting tabs 9 protruding from the side edge 21.

[0049] On the upper side, the front support part 4 has the at least one fastening element 4. Furthermore, a reinforcing section 22 is arranged above the at least one fastening element 4 and extends along an upper side edge 26. The reinforcing section 22 runs at an angle to the supporting wall 6 and, in the installed position, extends rearward from the fastening elements 4. The angle of the angular inclination to the supporting wall 6 is between 90° and 145°. Furthermore, in the embodiment shown, the reinforcing section 22 has an interruption 24 which is provided for the passage of a flushing pipe or an electrical cable or another element. In the embodiment shown, the front support part 5 has a tab section 30 in the area of the fastening elements 4 above the cutout 19 and below the interruption 24, which protrudes into the cutout 19.The stability of the front support part 5 can be further increased with the tab section 30.

[0050] The rear support part 7 has a cutout 19 in the rear wall 8 to provide the aforementioned recess 18. The cutout 19 is formed by two opposing side edges 20. A connecting tab 10 protrudes from each of the side edges 20 at a right angle to the support wall 6. At each of the lower side edges 21, which extend from the end of the side edge 20 at the lower end of the rear support part 7 to the support 2, a connecting tab 10 is arranged, which protrudes at a right angle to the rear wall 6. The lower side edge 21 extends essentially horizontally in the installed position. The connecting tabs 10 have a length viewed in the normal direction to the support wall 6. The length of the connecting tabs 10 protruding from the side edge 20 is the same as the length of the connecting tabs 10 protruding from the side edge 21.

[0051] On the upper side, the rear support part 7 comprises a reinforcement section 23. The reinforcement section 23 extends at an angle, preferably substantially at a right angle, from an upper side edge 26. In the installed position, the side edge 26 extends from one support 2 to the other support 2. The reinforcement section 23 serves to reinforce the rear support part 7 and further has openings 29, which serve for the attachment of sanitary articles, pipes, or other elements.

[0052] The reinforcement section 23 of the rear support part 7 is located at a distance from the reinforcement section 22 of the front support part 5. This distance creates an installation space 25.

[0053] In both support parts 5, 7, the connecting tabs 9, 10 extend essentially over the entire length of the side edges 20, 21.

[0054] In the connected state, the connecting tabs 10 of the rear support part 7 abut the inner surface 17 of the front support part 5 facing the rear support part 7 and thus the distance between the front support part 5 and the rear support part 7 is defined.

[0055] In the embodiment shown, the connecting tabs 9 of the front support part 5 are shorter in the area of the lower side edge 21 than the corresponding connecting tabs 10 of the rear support part 7. This is achieved by the Figure 7 This shortened design has the advantage that a weld, in particular a weld seam, can be formed on the front end 12 of the connecting plate 9 and the surface 13 of the connecting plate 10. The weld is in the Figure 7shown by the reference numeral 11. The other connecting tabs 9, 10, which are located to the left and right of the cutout 19, are of the same length on both support parts.

[0056] When connected, the support wall 6, the rear wall 8, the connecting straps 9, 10, and the supports 2 define a hollow body 14 with a cavity 15. In other words, the truss element 3 has a cavity 15. The aforementioned welding point 11 is preferably located outside the cavity 15.

[0057] The two support parts 5 and 6 are preferably made of sheet steel. In particular, by a punching process followed by a forming process. The connecting tabs 9, 10 are produced by a bending process during the forming process. The same applies to the optionally provided reinforcement sections 22, 23. After the two support parts 5, 6 are joined, they are typically connected to one another with welds. The cross member 3, which is provided by the front support part 5 and the rear support part 7, is then connected to the supports 2. The side edges 27 facing the supports 2 are welded to the supports 2 accordingly.

[0058] In the embodiment shown, the mounting device 1 further comprises two footrests 31, which are telescopically mounted in the support 2. The footrests 31 can be adjusted relative to the support 2 and locked in place at the set height.

[0059] In the illustrated embodiment, the supports 2 are designed as hollow profiles. The hollow profiles each have a rectangular cross-section.

[0060] The front surface 32 of the supports 2 spans a front plane F, and the rear surface 33 of the supports 2 spans a rear plane R. The truss element 3 is arranged such that it lies between the front plane F and the rear plane R. Preferably, the outer support wall 6 and the rear wall 8 lie in the front plane F and the rear plane R, respectively.

[0061] The weld seams mentioned herein may extend over the entire length of the corresponding edge or over partial lengths of the corresponding edge.
