Technical field

BACKGROUND OF THE INVENTION The present invention relates to a profile rail and a connecting element for supporting fixtures and fittings, in particular for sanitary installations, fittings, tubular parts and pipes, the profile rail having a longitudinally extending and outwardly open channel formed by a bottom wall and two opposite side walls, and in which a retaining projection is disposed for releasably fastening the fastener to the profile rail.

BACKGROUND OF THE INVENTION

In the prior art, DE 35 28 334 of the Applicant has become a known holding device for mounting the front wall of plumbing fixtures, fittings, pipe parts and ducts having a C-shaped sectional rail as well as connecting elements. These connecting elements connect a profile rail intended to be fixed to the building wall with a frame on which, for example, the sanitary device is fastened. The connecting elements consist in each case of two plate-shaped parts which are displaceable in the longitudinal direction and fixed in each position. In order to anchor the connecting elements to the profile rail, the side walls are bent inwards at their free edge. The angled portions of the side walls engage the corresponding slots of the fasteners. The fasteners swivel about their longitudinal axis for fastening and release. Thus, the profile rail has a truly C-shaped cross-section and not a U-shaped cross-section. In practice, the profile rail and this connecting element have proven themselves. However, the installation is relatively expensive, especially when several sanitary installations are to be installed in one row.

A utility model DE 92 16 789 has become known in the art for a similar holding device for mounting the front wall of sanitary articles and their connecting pipes. The C-shaped profile rail is also used here. The connecting elements are here designed as suspension hooks which are supported on the front edges of the profile rail. The fasteners are only suspended and

- They can freely move upwards. This in itself, the free anchoring of the fasteners is unfavorable during assembly.

EP 0 493 319 A2 has become known as a support system in which connecting elements as well as profile bars are used instead of profile rails. Profile bars are not suitable for their direct attachment to the building wall and are also not considered for this purpose.

SUMMARY OF THE INVENTION The object of the invention is to provide profile rails and a connecting element of the kind mentioned above, which allow even simpler and more rational assembly without tools, in particular elements arranged in a row and shaft frames as well as pedestals.

SUMMARY OF THE INVENTION

The problem is solved in that the retaining projection is embedded in the channel of the profile rail and the coupling element with the at least one coupling part engages appropriately in the channel.

In the profile rail according to the invention, the retaining projection is not embedded in the outer edge of the channel opening as it has been so far. The connecting element is not anchored suitably at the edges of the side walls, but inside the channel. Further, the opening of the channel can be formed as before, since the edges of the side walls do not have to be folded inwards.

F

The arrangement of the retaining projection at the channel depth opens the possibility of establishing a locking connection between the profile rail and the connecting element. In addition, the profile rail can then be used as a base element in the wide opening of the channel and the foot of the vertical handle can be incorporated therein.

According to a further use of the invention, the retaining projection is formed by at least two spaced, inwardly spaced and pointed curves of the bottom wall or side wall, and the connecting element has two spaced apart retaining portions which always accommodate the curvature. Such a profile rail can be produced extremely cheaply and the pointed bend is particularly suitable for anchoring the fastener, in particular by means of a locking connection.

A particularly suitable and functionally safe connection is obtained if at least one of the two retaining parts of the connecting element is designed to be resiliently retractable and extensible.

-3výstupok. The connecting element can then be used to fix it in the channel of the profile rail and, for example, be pushed in by a pivoting movement.

According to a further embodiment of the invention, the connecting element is angular and the arm engaging the profile rail extends in the longitudinal direction of the profile rail. This allows the anchoring element to be anchored while supporting the element on a wide section of the profile rail. Thus, in contrast to the point support of the fastener so far, a wide support and high stability of the fastener are achieved. With such a connecting element, two profile rails running at right angles to one another can very easily be releasably connected. With such profile rails and connecting elements, the frames or pedestals can therefore be mounted very stably and easily.

The invention also relates to a support device with a plurality of profile rails and connecting elements, wherein the profile rails have a bottom wall as well as two side walls, and the connecting elements are releasably fastened in at least one outwardly open channel of the profile rail in such a way that the profile rail and the connecting rails. the elements form a pedestal with vertical and horizontal profile rails. According to the invention, such a support device is characterized in that the profile rails each have at least one recessed, arranged retaining projection in their channel, which is formed by folding of the bottom wall or side walls and which is directed towards the inside of the channel. the projection releasably fastened. Such a support device can be manufactured very simply without the aid of profile rails and fasteners. The profile rails can be produced with a U-shaped cross-section and an open channel. One of the profile rails can be fixed to the floor of the building as a base profile and the lower end holds the vertical handle. The profile rails are also suitable for accommodating other fasteners and fasteners.

According to a further embodiment of the invention, a part which is externally applied to the profile rail and which engages in another profile rail and accommodates the curvature of the profile rail is provided as a further connecting part. This provides a particularly simple possibility of securing the profile rail to another part.

The anchoring of the fastener on the profile rail is preferably carried out as close as possible to the bottom wall. According to a further embodiment of the invention, therefore, a profile rail is provided in which the kinks have a distance to the bottom wall which is less than the height of the side walls. Preferably, this distance is equal to or less than half the height of the side walls. The connecting element is preferably designed to abut against the bottom wall of the profile rail. This means a particularly stable fastening of the connecting element to the profile rail. This is then particularly high when the connecting element is supported on two spaced apart feet.

Further advantageous embodiments follow from the dependent claims.

DETAILED DESCRIPTION OF THE INVENTION

Fig. 1 shows a connecting element 1, which consists of an angle 2 and two identical connecting structures 3, fastened to it by spot welds 6. The two arms 2a of the connecting element 1 are preferably, but not necessarily of equal length, clamping against each other according to

-5obr. 2c right angle. The connecting element 1 is preferably made of sheet metal, the two connecting elements 3 being preferably cut off from the profile.

The two connecting bodies 3 each have two spaced-shaped connecting parts 4 and 5 arranged in relation to one another. The connecting portion 4 comprises two approximately rectangular sections 4a and 4b extending to one another, the section 4a extending outwardly from the angle 2. Conversely, the connecting portion 5 is semicircular curved inwards and is provided with a notch groove 5a on the outside.

In FIG. 3 and FIG. 3c illustrates how the fastener 1 is fastened to the profile rail Z. This profile rail Z has a U-shaped cross-section and has a bottom wall 8 as well as two side walls 9 extending parallel to and perpendicular to the bottom wall 8. Bottom wall 8 and side the walls 9 form a channel 22 with an aperture 10 which, as is apparent, is substantially as wide as the width of the profile rail. The retaining lugs U are incorporated in both side walls 9 near the bottom wall 8. Each retaining lug 11 has a section 11a inclined to the bottom wall 8 by an angle α, as well as a section 11b extending relative to the wall 9 inclined by an angle β.

The angle α is preferably less than 45 ° and the angle β is approximately 90 °. The retaining lugs 11 are thus formed by sharp curves. The profile rail Z is preferably made of sheet metal. The bending of the profile rails is known to the person skilled in the art and need not be explained here.

To fasten the fastener 1 to the profile rail Z, the fastener in the inclined position shown in FIG. 3 and is inserted into the channel 22 in such a way that the connecting part 4 is supported by a section 4a of the retaining projection H. Now the connecting element 1 swings upwards into the position shown in FIG. 3b, unless the retaining portion 5 abuts the upper retaining projection

11. The pivoting movement is now carried out further and, with elastic deflection, the holding part 5 engages behind the upper holding projection 11 and finally, according to FIG. 3c the bend 11c of the upper retaining lip 11 inserted into the groove 3a. To loosen the connecting element 1, it is deflected in the reverse sense. As shown in FIG. 3c, the holding portions 4 and 5 abut on the bottom wall 8. The connecting element 1 is thus supported on the bottom wall 8 as well as on the two holding lugs U spaced apart from each other. This multiple and flat support stabilizes the coupling element 1 in the profile rail Z. Nevertheless, the coupling element can also be released by a pivoting movement even without tools. In the longitudinal direction of the profile rail Z, the connecting element 1 can be displaced. It is, of course, also possible to fix the connecting element in the longitudinal direction of the profile rail Z, for example by means of a clamping screw (not shown). The section 5a can also be provided with teeth (not shown) which are embedded in the profile rail Z. It is also possible and in certain cases expedient or necessary to deflect the profile rail with the fastening element fastened.

The profile rail Z can be according to FIG. 5, fastened by a plate-like connecting part 24 as well as by a screw 25 on the vertical handle 23. The handle 23 can be a Z-profile. As is apparent, the part 24 has a groove 27 in which the retaining projection 11 fits. Thus, the Z-profile is firmly releasably connected to the handle 23. The shaped engagement of the retaining projection 11 on the part 24 allows a high load on the profile rail Z.

Fig. 4 shows a further embodiment of the profile rail T having a retaining projection 30 which is incorporated into the bottom wall 31 of the profile rail T. The projection 30 is formed just like the projection 11 by bending. Advantageously, through holes 12 are incorporated in the holding projection 30 at regular intervals. These through holes 12 allow, for example, the rail 7 'to be fastened to the building wall (not shown). The bottom wall 31 forms a channel 33 with two parallel and straight side walls 32. The rail 7 'also has a U-shaped cross-section and has a wide opening 34 ·.

The connector 13 is fastened, as is obvious, to the retaining lug 30 releasably, with the upper tooth 17 retaining the retaining lug 30 and the lower grab 18 with the protrusion 18a engaging the retaining lug 30. The inner lug 19 abuts the retaining lug 30. a threaded rod 15 which is screwed into the projection 14 and can be fastened to an object (not shown), for example another rod or profile. The connecting element 13 can also be fixed or disengaged by deflection of the profile rail T.

Fig. 6 shows a profile rail T which is horizontally mounted here, for example, on a floor of a building not shown here. The profile rail T serves as a support for the vertical handle

37 having a shoe 21 which abuts on its underside a flat upper side 20 of the retaining projection 30. The surface 20 thus forms a closing surface for the shoe 21. The shoe 21 can be substantially as wide as the profile T because it is like As already mentioned, the channel 33 is wide open and, for example, is not narrowed by any curvature.

Fig. 7 and FIG. 8 illustrate a further embodiment of a fastener 38 which is intended to be fastened to the profile rail T. The fastener 38 is also formed as an angle and has two fasteners 39 having four toothed inwardly directed fasteners 39a. These connecting portions 39a are blocking formations and elastically deflect elastically when the connecting element 38 is inserted onto the retaining projection 30. As can be seen, the connection formations 39 are also supported on the bottom wall 31. In order to release the connecting element 38, the latter is deflected, thereby releasing the locking connection. Of course, the connecting element 38 can also be fastened firmly and the profile rail 7 'can be deflected as shown in FIG. 9 and FIG. 10th

Fig. 9 shows a connecting element 38 which connects the profile rail 7 'to another profile rail 7. The profile rail T is already connected, as explained above, to the connecting element 38. The profile rail 7' swivels in the direction of the arrow 48 and thereby fits into the connecting A second identical profile rail 72 'can be connected to the two profile rails 7' and 72 by means of suitable connecting elements (not shown).

Fig. 10 shows a rectangular connection between two profile rails 7 'and 7 by means of a connecting element 38. The connecting element 38 is engaged on the retaining projection 30 of the profile rail 7' at the desired height. For the connection of the profile rail 7 with the profile rail 7 ', the profile rail 7' is now deflected in the direction of the arrow 49 and is thus releasably fixed with the connecting element 38. If the profile rails 7 'and 7 are not fixed in another way, in the direction of the profile rail 7 '. Of course, the two profile rails 71 and 72 may be connected by other connecting elements 38 to the other profile rails in a frame or rack.

Fig. 11 shows, in sections, a front wall mounting frame 40 that is supported on the building wall 45 as well as on the floor 46 of the building. Two profile rails Z are used for this purpose, one of which is fastened to the floor 46 of the building by screws 44 and the other also here

-8 not shown by the screws on the building wall 45 in a horizontal design. The two vertical handles 41, one of which is covered here, each have a foot 42, which is embedded in a profile rail Z, fixed to the floor. As can be seen, the two retaining lugs 11 serve here as an abutment. The abutment on the building wall 45 is effected by at least two connecting elements 1, one of which is also covered. A threaded bolt 25 is fastened to each fastener 1, which is anchored in its connecting end 47 at its head end. By turning the bolt 25, the spacing of the frame 40 relative to the building wall 45 can be continuously adjusted. At the same time, another profile rail Z is firmly clamped on the frame 40 by the bolt 45 and the connecting part 24. The frame 40 is generally another profile rail (not shown here), additionally supported by the profile rail Z fixed at the top of the building wall. From the front side, the frame 40 may be covered, for example, with a plasterboard 50, and is suitable, for example, for attaching a toilet shell or washbasin 51. At the rear and front, the frame 40 may be supplemented with additional frames allowing mounting of the front wall of the row elements. For example, several toilet shells are mounted side by side on this frame.
