DESCRIPTION OF PREFERRED EXECUTION FORMS

[0028] The figures show two embodiments of a wall anchor arrangement according to the invention. Identical parts are provided with the same reference numerals.

[0029] The wall anchor arrangement according to both embodiments preferably serves to fasten a mounting frame to a building structure or a building wall. At least one sanitary fixture, such as a cistern, toilet bowl, urinal, washbasin, etc., is mounted on the mounting frame. The wall anchor arrangement comprises a wall anchor 2 and a mounting element 3 that can be connected to the wall anchor 2. The mounting element 3 can be connected to the wall anchor 2 in various ways, as explained below. This allows the mounting element 3 to have different functions. According to a first mode of operation, the mounting element 3 serves as a screw-in aid for the wall anchor 2, which can be screwed into a mounting profile. This first mode of operation is described in the Figures 2a, 2b and 6a, 6bshown. According to a second mode of operation, the mounting element 3 serves as a support element for the wall anchor 2 on a building wall when the wall anchor 2 is mounted without a mounting profile.

[0030] The wall anchor 2 comprises an anchor plate 4 with a front surface 5 and a rear surface 6, a fastening section 7 projecting from the front surface 5 of the anchor plate 4, and a snap-in section 9 projecting from the rear surface 6. The fastening section 7 extends along a central axis M and has a threaded structure 8 for receiving an anchor screw. The anchor screw can be used, for example, to connect the mounting frame to the wall anchor. The snap-in section 9 projects from the rear surface 6 and serves to snap the wall anchor 2 into a mounting rail.

[0031] For the mounting element 3, the wall anchor 2 has a first wall anchor-side bearing section 10 and a second wall anchor-side bearing section 11. The mounting element 3 has a first mounting element-side bearing section 12 and a second mounting element-side bearing section 13. The mounting element 3 can be connected to the wall anchor 2 either via the first bearing sections 10, 12 or via the second bearing sections 11, 13.

[0032] In the Figures 2a, 2b and 6a, 6bThe connection between the mounting element 3 and the wall anchor 2 via the two first bearing sections 10, 12 is shown. With this connection established between the mounting element 3 and the wall anchor 2 via the two first bearing sections 10, 12, a rotational movement can be transferred to the wall anchor 2, allowing the snap-in section 9 to be connected to a mounting profile via this rotational movement. The two first bearing sections 10, 12 are rotationally fixed to each other. When mounting the wall anchor 2 into a mounting profile, the installer can grasp the wall anchor 2 on the mounting element 3 and then insert it into the mounting profile with a rotational movement.

[0033] In the Figures 3a, 3b and 7a, 7bThe connection between the mounting element 3 and the wall anchor 2 via the two second bearing sections 11, 13 is shown. With the connection between the mounting element 3 and the wall anchor 2 established via the two second bearing sections 11, 13, the mounting element 3 covers the snap-in section 9 and provides a support for the wall anchor 2 on a building wall. This ensures that, when installed without a mounting profile, the wall anchor 2 rests on the building wall with the mounting element 3 and not with the snap-in section 9.

[0034] The mounting element 3 has a bearing opening 14, which provides the first bearing section 12 on the mounting element side. The first wall anchor-side bearing section 10 is located on the outside of the fastening section 7. When the two first bearing sections 10 and 12 are connected, the fastening section 7 projects through the bearing opening 14 and out of the bearing opening 14 opposite the anchor plate 4, so that the fastening section 7 remains accessible. The shape and size of the bearing opening are complementary to, or suitable for, the shape and size of the fastening section 7.

[0035] The storage opening 14 is provided by a wall structure 15. The wall structure 15 projects from a floor wall 18. The storage opening 14 extends through the wall structure 15 and the floor wall 18.

[0036] For the rotationally fixed connection, the first bearing section 12 on the mounting element side has a comb 17, and the first bearing section 10 on the wall anchor side has a groove 16, with the comb 17 engaging in the groove 16. In the first embodiment, one groove 16 and one comb 17 are arranged. In the second embodiment, two grooves 16 and two combs 17 are arranged. The grooves 16 and the combs 17 each have different widths.

[0037] In addition to the aforementioned base wall, the mounting element 3 also has a side wall 19, which projects from the base wall 18. The base wall 18 and the side wall 19 define a space 20 in which the snap-in section 9 comes to lie when the mounting element 3 is supported on the wall anchor 2 via the second bearing sections 11, 13. It is referred to the Figures 3a, 3b and 7, 7bThe floor wall 18 has a flat bearing surface 21 opposite the room area 20, with which the mounting element 3 can be brought into contact with a building structure. This provides good support for the wall anchor arrangement.

[0038] As from the Figure 1 and 5 As can be seen, the anchor plate 4 has an outer contour 22, which is at least partially complementary to the inner contour 23 of the spatial area 20. Complementary means that the outer contour is at least partially aligned with the inner contour, such that the anchor plate 4 can be inserted into the spatial area. The outer contour 22 comprises several corner areas, one of which is a corner and the other corner areas are each rounded.

[0039] The anchor plate 4 and the base wall 18 each have a congruent through-opening 24, which is congruent when the mounting element 3 is supported on the wall anchor 2 via the second bearing sections 11, 13. The through-openings 24 are located in the Figure 1 and 5 Clearly visible. A screw can be inserted through the opening 24 to fix the wall anchor 2 to the building wall.

[0040] The Figures 4 and 8In addition to the wall anchor arrangement 1, a sheathing panel 27 is shown. The mounting element 3 has at least one stop surface which provides a stop for the sheathing panel 27. In the illustrated embodiment, the entire outer surface of the mounting element 3 serves as a stop surface. The distance of the stop surfaces to the center of the bearing opening 14 is variable, allowing for different distances to be set. In the illustrated embodiment, the first bearing sections 10, 12 and the second bearing sections 11, 13 are arranged such that the distance between the central axis and the at least one stop surface, viewed transversely to the central axis M, is the same for the connection via the first bearing sections 10, 12 as for the connection via the second bearing sections 11, 13.

[0041] The wall anchor 2 according to the second embodiment further comprises a profile section 28. The profile section 28 projects from the fastening section 7 on both sides and is integrally formed with the fastening section 7. The bearing opening 14 has a shape that is designed to fit the profile section 28. The locking structures 25 are arranged in the area of ​​the bearing opening 14 and on the profile section 28.

[0042] Preferably the wall anchor 2 is made of a metallic material and the mounting element 3 is made of a plastic.

[0043] Thread structure 8 can be an internal thread, as in the Figures 1 to 4 shown, or be a threaded segment that is part of an insertion element which is slidably mounted on the fastening section 7.
