DESCRIPTION OF PREFERRED EMBODIMENTS

(14) FIGS. 1 to 4 show various views of the wall anchor 1 according to the invention. The wall anchor 1 comprises an anchor plate 2, a fixing portion 5 and two hooks 8, 9.

(15) The anchor plate 2 comprises a front face 3 and the rear face 4. The front face 3 and the rear face 4 are connected to a side face 13.

(16) The fixing portion 5 protrudes from the front face 3 along a centre axis M. The anchor plate 2 and the fixing portion 5 are here formed integrally with one another. The fixing portion 5 in the embodiment shown has the form of a cylinder. An opening 23 extends through the fixing portion in the direction of the centre axis M. The opening 23 serves to receive an anchor bolt 7 via which a mounting frame 25 can be fixed to the wall anchor 1. The anchor bolt 7 and mounting frame 25 are shown in FIGS. 10 and 12.

(17) The fixing portion 5 furthermore has a threaded structure 6 in which the anchor bolt 7 can be screwed. The threaded structure 6 is here part of a bracket element 33 which can be inserted in the opening 23, radially to the opening 23, so that the threaded structure 6 can be moved from an engagement position into a fast adjustment position. In the engagement position, the threaded structure lies in the opening 23 such that the anchor bolt 7 can be screwed into the threaded structure 6. In the fast adjustment position, the threaded structure 6 lies outside the opening 23 such that the anchor bolt 7 can be displaced in a longitudinal movement relative to the opening 23.

(18) The two hooks 8, 9, as shown in FIGS. 1 to 4, protrude from the rear face 4 of the anchor plate 2. The two hooks 8, 9 are configured such that the wall anchor 1 can be connected to protrusions 21 of the profile rail 19. The connection is such that the connection between the wall anchor 1 and the profile rail 18 is fixed relative to forces acting in the direction of the centre axis M. In the mounted state, the wall anchor 1 is firmly connected to the profile rail 18 via its protrusions 21, with respect to forces in the direction of the centre axis M.

(19) The hooks 8, 9 are configured such that the wall anchor 1 can be inserted in the profile rail 18 via a pivot movement executed about the centre axis M. In FIGS. 5 to 9, this pivot movement is shown in more detail. The wall anchor 1 is here inserted in the profile rail 18 in the orientation shown in FIGS. 5 and 6. Then the wall anchor 1 is pivoted about the centre axis M. FIG. 7 shows an intermediate position during the pivoting. In FIG. 8, the wall anchor 1 is shown in the fully mounted position. In the mounted or inserted position, the hooks 8, 9 grip around the protrusion 21 so that the above-described connection can be achieved.

(20) The shape of the two hooks 8, 9 is now explained using the illustrations in FIGS. 4 and 9. The hooks 8, 9 are arranged opposite one another relative to the centre axis M. Each of the hooks 8, 9 has a hook base 10 extending away from the rear surface 4. A hook portion 11 extends towards the outside from the hook base 10, radially from the centre axis M and inclined at an angle to the centre axis M. The hook base 10 and the hook portion 11 each form a receiving space or undercut which receives the protrusion 21.

(21) One of the two hooks, hook 8 in the figures, has a hook base 10 which is convexly curved around the centre axis. The pivot movement explained above with reference to FIGS. 5 to 8 is executed via this convexly curved hook base 10. The other of the two hooks, hook 9 in the figures, has a hook base 10 configured as a flat surface.

(22) In the embodiment shown, both hooks 8, 9 have a stop surface 26 which is oriented substantially at right angles to the centre axis M. The wall anchor 1 stands with the stop surface 26 on a base leg 19 of the profile rail 18.

(23) The hooks 8, 9 are arranged such that a free intermediate space 12, visible in FIGS. 4 and 9, is arranged between the two hooks 8, 9. The hooks 8, 9 are thus spaced apart from one another. The free intermediate space 12 has the advantage that a screw head 27 of the fixing screw 28, which attaches the profile rail 18 to a supporting structure, can protrude into the intermediate space 12. In other words, the wall anchor 1 can be positioned on the profile rail 18 irrespective of the positioning of the fixing screw 28.

(24) In the embodiment shown, the side face 13 at hook 8 is formed as a rounding. Preferably, the side face 13 is formed as a rounding at the hook which has the convexly curved hook base 10. The side face 13 at hook 9 has a first surface portion 15 and a second surface portion 16. The two surface portions 15, 16 are configured as flat surface portions which stand inclined at an angle to one another. On insertion of the wall anchor 1 in the profile rail 18, the first surface portion 15 runs parallel to a side leg 20 of the profile rail 18 before pivoting of the wall anchor 1. After pivoting of the wall anchor 1, the second surface portion 16 runs parallel to said side leg 20.

(25) It is furthermore evident from the side views of FIGS. 4 and 9 that the fixing portion 5 is arranged closer to the hook 8 than to the hook 9.

(26) Furthermore, the anchor plate 8 has a region 29 in which neither one of the two hooks 8, 9 nor the fixing portion 5 lies. This allows an installer to provide a passage hole in the region 29 in order to attach the wall anchor 1 without the profile 18, using a screw not shown in the figures.

(27) The fixing portion 5 has a length of 25 to 100 millimeter from the front face 3 to its free end 17. In other embodiments, the fixing portion 5 may also be longer or shorter.

(28) An arrangement as shown in FIGS. 5 to 9 comprises the profile rail 18 and at least one wall anchor 1. The profile rail 18 has a base leg 19 and two side legs 20 protruding from the base leg 19. Each of the side legs 20 has a protrusion 21. The protrusion 21 protrudes into the region between the two side legs 20.

(29) The base leg 19 is formed substantially flat and in the installation position lies flat on the supporting structure. The base leg 19 typically has a plurality of breakthroughs 22. The breakthroughs 22 each serve to receive a fixing screw 28, the screw heads 29 of which come to lie between the two protrusions 21.

(30) FIGS. 10 to 12 show a further development of the arrangement. The further development of the arrangement furthermore comprises a bottom rail 30 and a mounting frame 25. The bottom rail 30 has a receiving space 31 and is typically fixedly mounted on a building floor. Preferably, the bottom rail 30 and the profile rail 18 are identical. The mounting frame 25 has at least one foot support 37. The mounting frame 25 is placed with its at least one foot support 37 in the receiving space 31 and is then pivoted via a pivot movement relative to the profile rail 18. At the upper end, the mounting frame 25 has at least one fixing opening 32 in which an anchor bolt 7 is inserted. Here, two fixing openings 32 for two anchor bolts 7 are provided. The anchor bolt 7 is here in engagement with a wall anchor 1 as described above. The anchor bolt 7 is in engagement with the threaded structure 6 of the wall anchor 1. During mounting of the mounting frame 25, the at least one wall anchor 1 together with the mounting frame 25 is pivoted towards the profile rail 18. The pivot axis of the mounting frame 25 lies in the bottom rail 30. The at least one wall anchor 1, as shown in FIG. 6, is here moved into the profile rail 18 via the pivot movement of the mounting frame 25. The at least one wall anchor 1 can be connected to the profile rail 18 via the pivot movement described above and shown in FIGS. 6 and 7, about the centre axis M.

(31) In the embodiment shown, the mounting frame 25 has two vertical supports 34 spaced apart from one another which are connected via crosspieces 35. The crosspieces 35 have fixing structures 36, such as threaded openings or similar, on which a sanitary fitting may be attached.
