Description

[0001] The invention relates to a device for clamping fittings comprising a clamping clamp with two retaining clips forming a clamping receptacle between them and with a fixing stop for attaching the clamping clamp to a wall, wherein a fixing stop for attaching the clamping clamp to a wall projects from each retaining clip and wherein the stop plane of the fixing stops is normal to the longitudinal axis of the clamping receptacle and the retaining clips transition into the fixing stops at their end sections in the direction of the longitudinal axis of the clamping receptacle.

[0002] Such a device for clamping fittings or pipes is disclosed in JP 2004169324 A. KR3004567780004S (KR30_2009_0000883) discloses a holding device comprising a pipe clamp with two retaining clips. The mounting stops for attaching the clamp to a wall are formed by mounting lugs that project from only one retaining clip. Furthermore, the mounting planes of the mounting lugs on the wall run parallel to the clamping plane between the retaining clips, with the longitudinal axis of the pipe clamp lying in the clamping plane. The clamping device thus clamps fittings or pipes aligned parallel to a wall, but is not suitable for securing fittings protruding from the wall, in particular fittings with screw connections for receiving a tap or the like.

[0003] From DE102006017130B4, a holding device for fittings is known, comprising a pipe clamp with two retaining clips. The holding device is attached via a separate flange. This flange can be screwed directly to a wall. No adjustment of the clamping position along its longitudinal axis is provided. Such an adjustment may be necessary if the same device is required to clamp fittings that are flush with the wall at the opening, as is the case, for example, with plastered masonry, as well as fittings that protrude from the masonry, as is the case, for example, with masonry insulated with thermal insulation panels, so that the fittings are flush with the thermal insulation facade at the opening.

[0004] The invention is therefore based on the objective of improving a device of the type described above in such a way that it offers a variable installation option for mounting fittings or pipes.

[0005] The invention solves the problem by providing that the clamping receptacle provided between the retaining clips can be connected to a fitting in a form-fitting manner and is rotationally fixed, and in particular has a polygonal cross-section, and that the fastening stops have predetermined breaking points for shortening the installation width.

[0006] This means the clamp can be connected to a fitting not only by force but also by form, which means that the fitting is securely held against rotation around the clamp's longitudinal axis on the wall. This allows, for example, a tap or similar fitting to be screwed into a threaded fitting to connect the tap to a water pipe without the fitting and pipe rotating, as it is secured to the wall by the clamp and its mounting stops.

[0007] The mounting stops also feature predetermined breaking points for shortening the installation width. By selectively shortening the mounting stops at these predetermined breaking points, the stop position of the clamp can be adjusted to meet specific installation requirements.

[0008] The technical effect is that the fitting can be installed either with the opening at least nearly flush with the wall or with it protruding from the wall. This is easily achieved by rotating the clamp 180° around an axis located in the mounting plane and attaching it to the wall in this way. Thus, the component can function as a flush finish for a pipe penetration through a wall or project a predetermined length beyond the wall to compensate for optional wall cladding. The fitting can therefore be clamped either within the wall or in front of it, with the mounting stops being equally suitable for wall attachment, specifically by screwing or gluing. The clamp is typically made of sheet metal or, if necessary, plastic, with stamped sheet metal parts being preferred for higher-strength applications.

[0009] The retaining clips can each have two radially outward-projecting flanges for connecting the two retaining clips, which form a clamping receptacle between them. The retaining clips can thus be easily screwed together by clamping a fitting.

[0010] For sound decoupling, a damping element can be attached to the clamping receptacle of the retaining clips, which is clamped specifically between the fitting and the retaining clips. Rubber-elastic materials, for example, are used as damping elements. This damping element decouples the fitting from the wall, thereby dampening structure-borne noise transmission.

[0011] The mounting stops may have elongated holes for attaching the clamp to a wall in order to provide suitable tolerance compensation during installation.

[0012] If the retaining clips of the clamp are identical parts, only one tool is needed to manufacture the clamp.

[0013] In summary, the device according to the invention for clamping fittings enables flexible and secure fixing of straight and angled fittings to a wide variety of building components, particularly walls. The integration of an insulating insert allows for structure-borne sound decoupling to reduce unwanted vibrations and noise. The variable fastening option enables a customized application according to individual needs.

[0014] The invention is illustrated in the drawing as an example. It shows Fig. 1 a device according to the invention for clamping fittings in a first assembly variant in oblique view, Fig. 2 the device from Fig. 1 in partial section in a view parallel to a stop plane, Fig. 3 the device from Fig. 1 in a second mounting variant in oblique view and Fig. 4 the device from Fig. 3 in partial section in a view parallel to the stop plane.

[0015] The device according to the invention for clamping fittings 1, here a fitting which has a screw connection at one end and a pipe receptacle at the other end, comprises a clamping clamp 2 with two retaining clips 4 forming a clamping receptacle 3 between them and a fixing stop 5 for fixing the clamping clamp 2 to a wall 6.

[0016] Each retaining clip 4 has a mounting stop 5 for attaching the clamp 2 to a wall 6, wherein the stop plane 7 of the mounting stops 5 is normal to the longitudinal axis 8 of the clamping mount and the retaining clips 4 transition into the mounting stops 5 at the end section in the direction of the longitudinal axis of the clamping mount.

[0017] The retaining clips 4 each have two radially outwardly projecting flanges 9 for connecting the two retaining clips 4 which form a clamping receptacle 3 between them.

[0018] The clamping receptacle 3 provided between the retaining clips 4 is positively interlocking and rotationally fixed to a fitting 1 and for this purpose has in particular a polygonal, here hexagonal, cross-section.

[0019] A damping element 10 for sound decoupling is assigned to the clamping receptacle 3 of the retaining clips 4.

[0020] Furthermore, the mounting stops 5 have predetermined breaking points 11 for shortening the installation width. The mounting stops 5 have elongated holes 12 for attaching the clamp 2 to a wall 6. The retaining clips 4 of the clamp 2 are identical parts, preferably identical parts formed from a single piece of sheet metal.
