Abstract:
The attachment plate has a rectangular planar front wall (2) with two groups (3) each with three mounting sites (3a-3c). These groups are used for mounting sanitary fixtures such as for example isolating valves and the like. The two groups (3) have in each instance two mounting sites (3b, 3c) disposed on a straight line (A). Each group (3) has moreover at least one third mounting site (3a) at a distance (Y) one from the other which is different from the distances (X, Z) of the remaining mounting sites (3b, 3c). The mounting sites (3a-3c) are disposed in such a manner on the attachment (1) that all commonly used sanitary fixtures and the like can be mounted.

Description:
The present invention relates to an attachment plate for mounting for example sanitary fixtures such as for example isolating valves, safety groups, corner valves and surface fixtures, in particular for installation of fronting walls, with at least two mounting sites disposed in a face wall of the plate. 
     BACKGROUND OF THE INVENTION 
     A known fixture plate of this type comprises two mounting sites disposed at a distance one from the other in the form of breakthroughs. The one breakthrough is a circular bore and the other breakthrough is formed by two overlapping bores. The one or the other of the overlapping bores may be used for mounting for example a fixture so that in this attachment plate two different gauges for bore holes are available, a fact which simplifies the storage of such fixture plates. In practice, however, a large number of gauges for bore holes are required since the selection of different sanitary fixtures is very large. Consequently, several types of the known attachment plates would have to be kept in stock. 
     An attachment plate or mounting device is also known on which fixtures placed onto the front wall can be mounted at the front face by means of self-tapping screws. The fixtures are here provided with an outer flange on which they are mounted to the plate by screws. The mounting sites in this attachment plate are bores disposed circularly into which the tapping screws are screwed when mounting a fixture. In this case the conduits leading to the fixtures are not carried through the attachment plate but rather laterally away from it. With this plate the difficulty also exists that there must be kept several implementations in stock. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is to provide a fixture plate of the stated type which is suitable for all fixtures. The fixture plate should nevertheless be capable of being manufactured in compact construction and with comparatively small external dimensions. The object is achieved according to the invention as defined to claim 1. In an attachment plate with the configuration defined in the characterizing part of claim 1 of the mounting sites, six mounting sites suffice in order to be able to mount the most common fixtures. An optimum number of mounting sites in an optimal configuration is also described. The configuration defined here nevertheless permits a very compact implementation of the fixture plate, and also permits the implementation of a further mounting site on the center line of the plate for the central mounting of a fixture. The front wall can be for example rectangular and can be produced with comparatively small external dimensions and comparatively small distances of the breakthroughs from the edge of the plate. It is also essential that the configuration of the mounting sites in two groups with three mounting sites each and also in the implementation with a seventh central mounting site be configured very distinctly. Consequently the mounting is at least as simple as it has been in the prior art. 
     Recesses comprising several overlapping breakthroughs, which can impair the stability of the attachment plate, can be avoided. 
     The dimensions and configurations stated in the dependent claims permit a still further optimization of the opening of the attachment.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The attachment plate 1 shown in FIG. 1 comprises a rectangular and planar front wall 2 and side walls 5 and 6 bent towards the rear at 90°. For mounting the attachment plate 1 on a supporting frame 10 shown here only partially, the plate has recesses 4a and 4b in the front face 2 and in the side walls 5 and 6. Latch 15, which is only barely shown, may be introduced through the recesses. The latch connects detachably the attachment plate 1 with the supporting frame 10 whereby it engages with a head, not shown here, dovetail grooves 11 as well as channels 12. As a rule, the attachment plate 1 is connected with several latches 15 of the same type on opposite sides with the frame 10. For positioning the attachment plate 1 on the frame 10 the side walls 5 and 6 comprise projecting lugs 7. In the same manner the attachment plate 1 may also be mounted on frame 10 rotated by 90° so that the side walls 6 also are in contact with the support of the frame 10. 
     The front wall 2 comprises two groups 3 of three mounting sites each in the form of breakthroughs 3a, 3b, and 3c. The two groups 3 are disposed symmetrically in mirror image with respect to a line S. The breakthroughs 3a and 3c are preferably circular and have a diameter of 30 to 36 mm, preferably 33 mm. The centers of breakthroughs 3b and 3c are disposed on a straight line A which is parallel to a lower edge 13. It is clear especially in FIG. 1 that in each group 3 the breakthrough 3a is disposed above the two breakthroughs 3b and 3c. However, the distance between the two breakthroughs 3a is different from the distance between the two breakthroughs 3c and also different from the distance between the two breakthroughs 3b. Furthermore, the distance between the two breakthroughs 3a is different from the average of the distances between breakthroughs 3c or 3b, respectively. The corresponding distances are denoted in FIG. 2 with X, Y, and Z. The distance between line A and line B through the centers of breakthroughs 3a is designated by W. For the greatest possible applicability of the attachment plate 1 these distances as well as the diameter of the breakthroughs 3a to 3c are essential and are given in the following table. 
     W=40 mm 
     X=153 mm 
     Y=100 mm 
     Z=76.5 mm 
     Deviations from the above distances are possible but lead, as a rule, to an opening which is less than the optimum. Deviations of the diameter of the breakthroughs 3a to 3c as well as deviations from the circular shape of these breakthroughs are also conceivable. Conceivable is also an implementation in which the front face 2 comprises more than 6 breakthroughs for lead-throughs. An attachment plate with a seventh mounting site on the line of symmetry S would also be suitable for an additional central mounting of a fixture. 
     The front face 2 is preferably rectangular and has a length L of 248 mm and a height H of 120 mm. The depth of the side walls 5 and 6 is designated by T in FIG. 2 and is preferably 32 mm. For an especially optimal implementation of the fixture plate 1 these dimensions are also essential but it is understood that slight deviations are possible. The dimension T corresponds preferable to the profile width. 
     In FIGS. 2 to 5 are shown some typical examples of the applications of attachment plate 1 according to the invention. 
     In the arrangement according to FIG. 2 an isolating valve 15 is mounted on the attachment plate 1. The breakthrough 3c used for the mounting is covered by a rosette 16. Clearly a second isolating valve 15 or another fitting may be mounted on the attachment plate 1. 
     FIG. 3 shows an attachment plate 1 on which is mounted a safety group 17. The latter has two conduits 18 and 19 which go through the two breakthroughs 3a and are mounted on them. Also in this case the breakthroughs are covered by rosettes 16. 
     FIG. 4 shows an attachment plate 1 on which are mounted washstand fittings with a siphon trap 22 and a valve 20. In the case of this attachment plate a breakthrough 3a is used as well as a breakthrough 3b. Through the breakthrough 3b a screw neck 21 of the siphon trap 22 is guided from the rear. 
     FIG. 5 shows an attachment plate 1 on which is mounted a so-called mixed-water fixture 23. The latter comprises an actuation lever 33 as well as a spout 34. Lines 24 and 28 for warm or cold water, respectively., lead through breakthroughs 3b. Here also is provided in each instance a covering with a rosette 16. If the distance between the two lines 24 and 28 is shorter, breakthroughs 3c or 3a are used correspondingly. However, the use of a breakthrough 3b and a breakthrough 3c is also possible. 
     The mounting battery 23 on the plate 1 is shown in FIG. 6. Pipe 24 comprises an outer flange 31 which rests on the rear side of the front wall 2. On the opposite side of the front wall 2 is applied a counternut 32 which is screwed onto the outer threads 55. Between the flange 31 and the counternut 32 is placed in the breakthrough 3a a packing ring 30 made of a sound-absorbing material, for example rubber. Finally, a rosette 16 mentioned hereinabove is placed onto the line 24. The dimensions of the ring 30 depend on the outer diameter of line 24. In the case of a small outer diameter, a ring 30 with a smaller inner diameter is selected accordingly. Lateral displacement of line 24 is prevented in every case. Consequently lines 24 with different outer diameter may readily be mounted on the attachment plate 1. 
     Lugs 53 on the rear side of the front wall 2 which engage corresponding recesses 54 of the flange 31 facilitate the aligning of the fixture during the mounting operation. A suitable arrangement of these lugs 53 is shown in FIG. 1. In FIG. 2 these lugs 53 are not shown for reasons of clarity. 
     FIG. 7 shows an attachment plate la in which each mounting site comprises eight bores 35 which are disposed in a circle 37. As shown schematically in FIG. 9 this plate serves for mounting fixtures 39 which comprise an outer flange 42. The latter may be mounted by means of tapping screws 41 which are screwed into bores 35. The lines 40 leading to the fixture 39 in this case do not pass through the attachment plate 1a and the corresponding breakthroughs may here be omitted. 
     In addition to the bores 35, breakthroughs 3a to 3c are provided in the implementation according to FIG. 8. In this case the mounting shown in FIG. 10 of a line piece 43 provided with a flange 45 is possible. The fitting is here screwed onto external threads 44 of the line piece 43. Here are self-tapping screws 41 screwed into corresponding bores 35 of the attachment plate 1b. Accordingly, a mounting site comprises in attachment plate 1b in each instance a breakthrough as well as several bores 35 disposed around it. 
     Finally is shown in FIG. 11 an attachment plate which also comprises two groups each with three mounting sites. However, here two mounting sites or breakthroughs 3a and 3b are disposed on a straight line K extending obliquely and a third mounting site 3c is offset with respect to the former. The above stated distances X, Y, and Z, however, are also maintained in this implementation. In contrast with the other implementations described hereinabove, here a greater height H of the plate must be provided. The openings and latches, explained in connection with FIGS. 1 and 2, for mounting the attachment plate on a supporting frame 10 are also provided in the case of the attachment plates 1a to 1c. However, they are not shown in the corresponding Figures.
