The device 41 according to FIG. 7 consists of a circular profile piece 42 with a front hole 43 for receiving a carrier 44. The preferably tubular support 44 has a threaded connection at the end 45, by means of which the carrier 44 via a Screw connection 46 can be fixed in the bore 43. A nose-shaped projection 47 does not serve together with one Groove shown in the carrier 44 as a securing device.

The profile piece 42 in turn has one on its back horizontally projecting flange-shaped leg or Boom 48 which, like the profile piece 42 in the Cross-section is kept circular cylindrical. On his The flange-shaped leg 48 in turn has an underside stepped or step-shaped recesses 50, 51, the Width b1 or b2 is dimensioned such that different Wall thicknesses of the walls 54-60 shown in FIGS. 8-12 can be taken into account or pinched.

The one shown in FIG. 7, preferably in cross section circular cylindrical profile piece 42 has a downward directed, essentially rectangular in cross section Support arm 61, which in turn has a rear another, horizontally aligned flange-shaped leg or boom 62. This flange-shaped too Projection has a U-shaped on its lower side 63 Recess 64 on that as the lower, vertical extension of the upper U-shaped recess 50, also with a width b1 is formed. This recess 63 also serves Enclose or to hang an associated wall 54.

The use of device 41 is various Variants shown in Figs. 8-12. For this, the Wall an upper 65 and lower 66 bore on, according to Embodiment according to FIGS. 7-12 in general are circular cylindrical.

The diameter D ₁ or D _{2 of} the bores 65, 66 or their clear width is dimensioned such that at least the diameter D _{3 of} the upper flange-shaped leg 48 can pass through the bore 65 (D ₁ ≈ D ₃ ). The diameter D _{4 of} the lower flange-shaped leg 62 is generally made smaller than the diameter D _{2 of} the associated wall bore 66.

The bores 65, 66 in the walls 54ff are therefore made such that the upper and lower legs 48, 62 can be inserted horizontally. After the horizontal insertion, the respective wall is introduced into a respective recess 50, 51, 64, that is to say the recesses 50, 51, 64 encompass the respective wall section with their lateral contact surfaces 52, 53, 67. Accordingly, the lower edges 68, 69 of the bores 65, 66 must be matched in their spacing l ₁ to the respective spacing l _{2 of} the corresponding contact surfaces of the recesses 50, 51, 64. The lower end edge 70 of the lower flange-shaped leg 62 can also have a corresponding one Form contact surface (see Fig. 9).

As can be seen from FIGS. 8, 9, the profile piece 42 with the upper flange-shaped leg 48 and the lower flange-shaped leg 62 is accordingly inserted horizontally into the respective bore 65, 66 of a wall of different thickness 54, 55 and pushed downward. The width B _{1 of} the wall 54 is then enclosed by the width b _{1 of} the recesses 50, 64 when it is pushed down vertically. Likewise, the larger width B _{2 of} the wall 55 is laterally encompassed by the larger width b _{2 of} the recess 51 adapted to it, so that there is a form-fitting embedding. In the lower area, the lower end edge 70 is available as a contact surface of the flange-shaped leg 62 in the bore 66. The lower leg 62 also serves to prevent rotation of the device.

The further exemplary embodiments according to FIGS. 10-12 represent Variants of the invention. FIG. 10 shows a additional insert 71 in a larger bore 72 in the Wall 56. The insert 71 forms a circumferential Attachment flange 73, the lower region 74 of which corresponding support hole forms, as is analogous to FIG. 9 shows. The dimensions of the device 41 are such dimensioned that the lower flange-shaped leg 62 on the Outer wall 56 rests, while the upper region of the Profile piece 42 rests on the attachment flange 73. A Protection against rotation is provided by a contact surface 76 (see Fig. 10) which form-fit in a recess of the Insert 71 fits.

The embodiment variant according to FIG. 11 shows an analog one 8, however, the wall 54 as Wall 58 is screwed against a further wall 57. The Screw connection is shown at 75.

Finally, the illustration according to FIG. 12 shows one combined use of several walls 59, 60 of which Total width B3 corresponds to the width b2 of the recess 51. Basically, the wall widths are unique or dimensioned in a composition of walls such that they form-fit from the recesses 50, 51 of the upper flange-shaped leg 48 are enclosed. At the bottom The area of device 41 can generally be the lower End edge 70 of the flange-shaped leg 62 as Contact surface can be used and also as Serve against rotation.

The device 1 shown in FIG. 13 for detachable Holder for a profile piece used for a wall bracket 80 includes an insert 81 which is in a bore 82 of a wall 83 can be inserted, a slotted ring 84, which a rear, tapered portion 85 of the insert 81 is pushed, and a sleeve 86, which is in its front Area 87 is pushed onto the tapered section 85. The profile piece 80 is over a flange-shaped leg e.g. into a recess 95 in the insert 81 of the device mounted. The slotted ring 84 and the sleeve 86 are for better understanding each individually in one Side view and a front view in Figures 14a and b and 15a and b are shown.

The device 1 according to the invention is as follows Bracing mechanism anchored in bore 82: By means of a screw (not shown), which in a z. B. centric Bore 88 inserted in the rear wall 89 of the insert 81 and in a bore 90 with a corresponding thread in the bottom 91 of the sleeve 86 is screwed in, the sleeve 86 is against the insert 81 pulled and pushes itself further over the tapered section 85 of the insert 81 against the slotted ring 84. However, the slotted ring 84 abuts its end opposite the sleeve with an oblique cone-like contact surface 92 of a correspondingly designed Chamfer 93 at the beginning of the tapered section 85 of the Insert 81 opposite; so that an axial movement of the ring by the compressive force of the sleeve 86 over the inclined surfaces is also deflected outward in a radial movement. As a result, the ring, which has a slot 94, spreads until it strikes the inner wall of bore 82 and tense up there. With the ring are also the sleeve 86 and the insert 81 connected via the screw in the Hole 82 firmly anchored.

The angle α of the conical, oblique contact surface on slotted ring 84 with respect to the bore axis and the corresponding angle of the chamfer on the insert 81 is e.g. 45 °.

Due to the clamping mechanism described, a Device are provided, which, if provided Minimum is not undercut for any Anchoring wall thicknesses in the simplest way.

The invention is not based on that described and illustrated Embodiment limited. Rather, it includes everyone Further training in the context of property rights claims.
