DESCRIPTION OF PREFERRED EMBODIMENTS

[0052] In the drawings, a mounting system 1 for fastening a sanitary fitting is shown. The mounting system 1 comprises a mounting frame 2 and a fastening unit 6. By means of the fastening unit 6, the mounting frame 2 can be fastened to a supporting structure, such as a wall of a building or a profile element.

[0053] The mounting frame 2 comprises at least one hollow profile 3 which is in the form of a vertical support in the embodiment shown. The hollow profile 3 has side walls 4 which define an internal space 5. The hollow profile 3 extends along a profile axis P. At the end thereof, the hollow profile 3 has an end face 10. In the region of the end face 10, the hollow profile 3 has an open design. In the embodiment shown, the mounting frame 2 further comprises a cross member 35 which in this case extends away from the upper end of the hollow profile 3 and is oriented substantially at right angles to the profile axis P. In the installed position, the cross member 35 extends in the horizontal direction. Typically, another hollow profile (as shown in FIGS. 8 and 9) is arranged on the other side of the cross member 35, said hollow profile forming another vertical support. Furthermore, the mounting frame 2 can have additional cross members.

[0054] The mounting frame 2 further comprises at least one bearing structure, on which a sanitary fitting can be mounted, that is to say rigidly fastened. The bearing structure is for example a threaded opening into which a threaded rod can be screwed. The bearing structure is preferably fastened to one of the above-mentioned cross members.

[0055] The fastening unit 6, as shown in FIGS. 1 and 2, is inserted from above into the internal space 5 of the hollow profile 3. The fastening unit 6 comprises a support element 7, which has a guide receptacle 8, and a fastening tab 9 which is movably mounted in the guide receptacle 8. The fastening tab 9 is mounted in the guide receptacle 8 so as to be able to slide relative to the fixed support element 7 from a starting position into a mounting position. In FIGS. 1 to 3, the fastening tab 9 is shown in the starting position. In FIGS. 4 to 6, the fastening tab 9 is shown in the mounting position. In the mounting position, the part of the fastening tab 9 which projects out of the guide receptacle 8 or out of the internal space 5 is inserted to fasten the mounting frame 2.

[0056] The support element 7 can be inserted into the internal space 5 of the hollow profile 3. In the mounting position, the fastening tab 9 projects out of the guide receptacle 8 and out of the internal space 5 beyond the end face 10 of the hollow profile 3. The fastening tab 9 can then be inserted to mechanically fasten the mounting system 1 with respect to a supporting structure, such as a wall or another profile.

[0057] From FIGS. 1 to 6, it can be seen that the support element 7 is located completely inside the internal space 5 of the hollow profile 3. When viewed from the internal space 5, the support element 7 does not extend beyond the end face 10. In the mounting position, the fastening tab 9 is also located completely inside the internal space 5. In the starting position, the fastening tab 9 accordingly does not extend beyond the end face 10. In the mounting position, the fastening tab 9, as mentioned above, extends beyond the end face 10.

[0058] The guide receptacle 8 is in the form of a longitudinal guide. In this case, the longitudinal guide is designed in such a way that the fastening tab 9 is slidable substantially in the direction of a longitudinal axis L of the longitudinal guide. The longitudinal axis L is oriented parallel to the profile axis P of the hollow profile 3.

[0059] From FIGS. 2 and 5, it can be seen that the hollow profile 3 and the support element 7 have an aperture 11. The aperture 11 is arranged in such a way that the fastening tab 9 can be gripped through the aperture 11 from the outside and can be moved from the starting position into the mounting position. The aperture extends through the side walls of the hollow profile 3 and the support element 7.

[0060] In FIGS. 7 and 8, exploded views of the mounting system 1 are shown. In the embodiment shown, the fastening tab 9 has a guide portion 12 and a fastening portion 13. In the mounting position, the fastening portion 13 is located outside the guide receptacle 8, and the guide portion 12 is located inside the guide receptacle 8. In the starting position, both the fastening portion 13 and the guide portion 12 are located in the guide receptacle 8.

[0061] A shoulder portion 14 is arranged between the guide portion 12 and the fastening portion 13. The shoulder portion 14 is formed in such a way that a mounting face 16 of the fastening portion 13 comes to lie substantially flush with an outer face 17 of the hollow profile 3 when the fastening tab 9 is located in the mounting position. This is shown correspondingly in FIG. 6. The mounting face 16 lies substantially flush with the outer face 17. It is thus ensured that the mounting frame 2 can be arranged on a supporting structure flush with the outer face 17.

[0062] Preferably, when viewed in the direction of the longitudinal axis L, the guide portion 12 is designed to be longer than the fastening portion 13. However, the guide portion 12 can also be designed to be shorter than or the same length as the fastening portion 13.

[0063] FIGS. 3 and 6 show that the guide receptacle 8 has a first guide face 19 and a second guide face 20. The fastening tab 9 is arranged between the first guide face 19 and the second guide face 20. The second guide face 20 has a spring tension applied thereto by a spring element 21. The second guide face 20 thus presses the fastening tab 9 against the first guide face 19. In FIG. 3, in which the fastening tab 9 is located in the starting position, the distance between the two guide faces 19, 20 is greater than in FIG. 6, in which the fastening tab 9 is located in the mounting position. By means of the arrangement of the spring element 21 and the movable second guide face 20, the fastening tab 9 is lightly clamped in the guide receptacle 8. The clamping is such that the fastening tab 9 cannot move due to its own weight, and an installer can pull out the fastening tab 9 without applying a great deal of force.

[0064] In this case, the spring element 21 is an integral component of the support element 7. The guide faces 19, 20 are also integral components of the support element 7.

[0065] In the embodiment shown, the spring element 21 comprises two curved spring legs 36. The spring legs 36 are part of the support element 7 and protrude from a side wall 23 of the support element 7. In the embodiment shown, the support element has a hollow space 25. The spring element 21 is arranged in the aforementioned hollow space 25 and protrudes from an inner wall face 26 of one of the side walls 23.

[0066] The guide receptacle 8 further comprises two lateral guide faces 22 which in this case extend substantially at right angles away from the first guide face 19.

[0067] In the mounting position, the fastening tab 9 is snapped into the hollow profile 3 by means of a snap connection 33. The snap connection 33 comprises a snap-in tab 38, which protrudes from the fastening tab 9, and a snap-in opening 39 which is arranged in the hollow profile 3. In FIG. 6, the engagement of the snap-in tab 38 in the snap-in opening 39 is shown. The snap connection 33 is designed in such a way that the fastening tab 9 is prevented from being pulled further out of the guide receptacle 8, and it is possible to slide the fastening tab 9 out of the mounting position back into the starting position.

[0068] The support element 7 has side walls 23 having outer wall faces 24. The outer wall faces 24 have a cross-sectional shape which is substantially the same as the cross-sectional shape of the internal space of the hollow profile 3. In the embodiment shown, the hollow profile 3 has a rectangular, in this case square, cross section. Accordingly, four side walls 23 are arranged with correspondingly outer wall faces 24.

[0069] Preferably, at least one spring portion 37 protrudes from at least one of the wall faces and acts against the inner wall of the hollow profile.

[0070] The support element 23 is preferably fastened in the internal space 5 of the hollow profile 3 by means of at least one snap connection 27. The snap connection 27 is provided by a snap-in tab 28 moulded on the support element, which tab engages in a snap-in opening 29 located in the hollow profile.

[0071] Furthermore, the support element 7 and the hollow profile 3 each have a stop 30, the two stops 30 being in contact with one another when the support element 7 is inserted.

[0072] Furthermore, the hollow profile 3 and two sides which are opposite one another with respect to the internal space each have one opening 31. Furthermore, the support element also has an opening 32. When inserted, the two openings 31, 32 form a mounting opening through which a fastening screw 34 can be guided. In the embodiment shown, the support element also has a corresponding opening, and the fastening screw can also be guided through the support element.

[0073] As explained at the outset, the mounting frame preferably has two hollow profiles 3 arranged at a distance from one another, which profiles are in the form of vertical supports. Each of the hollow profiles 3 preferably has one fastening unit 6 each, which is inserted at the upper end of the respective hollow profile 3. This is shown in FIGS. 8 and 9.

[0074] FIG. 8 shows the mounting system with further details. In particular the at least one bearing structure 40 is shown. In this embodiment it is located on a cross member 35 which is rigidly connected to the vertical supports 3.

[0075] Furthermore, FIG. 9 shows an assembly with the sanitary fitting and the mounting system as described above.
