Description

TITLE

MOUNTING DEVICE

TECHNICAL AREA

The present invention relates to a mounting device for fastening at least one sanitary article according to the preamble of claim 1.

STATE OF THE ART

Mounting devices for fastening sanitary articles are known from the prior art. Such mounting devices are permanently installed behind a front wall and are used to store sanitary items such as cisterns, toilet bowls, urinals, fittings, washbasins, control elements, electrical elements, etc. EP 2 662 502, for example, discloses such a mounting device.

Although very good results are achieved with the assembly devices from the prior art during assembly in a building, it is desirable for the manufacturer to simplify production. Many of the known mounting devices are very complex to manufacture.

PRESENTATION OF THE INVENTION

Proceeding from this prior art, the invention is based on the object of specifying a mounting device for fastening at least one sanitary article, which overcomes the disadvantages of the prior art. In particular, it is an object of the present invention to specify a mounting device for the attachment of at least one sanitary article, which is simpler and more efficient to manufacture.

This object is achieved by the subject matter of claim 1. Accordingly, a mounting device comprises two spaced-apart supports, which each extending along a central axis and each having a support cross-section, a first traverse extending along a central axis and having a traverse cross-section, which is firmly connected to the supports and connecting the supports to one another, and a second traverse extending along a central axis and having a traverse cross-section , which is firmly connected to the supports and connects the supports to each other. The second traverse is spaced apart from the first traverse and, seen in the installation position, is arranged above the first traverse. The traverse cross-section of at least one of the traverses mentioned is essentially the same or is designed to be the same or identical to the support cross-section of the supports.

The formation of the at least one traverse with a cross section that is formed equal to the cross section of the support has the advantage that the manufacture of such a mounting device becomes easier. If said at least one traverse and the supports are produced by means of a forming process, said at least one traverse and the supports can be produced on the same production line without any further conversion, as a result of which production is optimized. If said at least one traverse and the supports are made from prefabricated profiles, storage can be optimized because the number of profiles to be kept in stock is reduced.

A further advantage arises when the supports are connected to the at least one traverse with the same cross section. Due to the same cross-section, the traverse and the support can be positioned on a flat surface, as a result of which the at least one traverse and the supports are already in the correct plane, thus eliminating the need for an alignment process relative to said surface.

Another advantage is the increased stability of the assembly device. Due to the same cross section, the installation space between a front plane, which is spanned by the front surfaces of the support, and a rear plane, which is spanned by the rear surfaces of the support, is fully utilized by the at least one traverse. The cross-section of the traverse can thus be maximized, which is advantageous for absorbing the different mechanical loads.

The phrase “essentially the same cross section” is understood to mean that the cross sections of the respective supports or of the at least one traverse apart from any opening in the walls of the supports or the trusses are identical or corresponding to each other. Such openings are used to attach and/or position sanitary articles.

The truss cross-section of the truss is defined as a section perpendicular to the central axis of the truss. The column cross-section of the columns is defined as a section perpendicular to the central axis of the columns.

Said at least one traverse and the two supports preferably have the same cross-section over their entire length. This apart from the openings mentioned above.

In the installed position, the supports run in the vertical or the plumb direction and the traverses run in the horizontal, that is to say essentially transverse to the plumb direction. The supports can therefore also be referred to as vertical supports.

Preferably, the traverse and support cross sections that are designed to be identical to one another are identical in terms of cross-sectional geometry and/or cross-sectional area. This means that the traverse cross-section of said at least one traverse is designed to be the same as the support cross-section in terms of cross-sectional geometry and/or cross-sectional area.

Preferably, the external cross section of the supports and the at least one traverse is the same with the traverse and support cross sections designed to be identical to one another. The term "external cross-section" means the external shape of the traverse or the traverse.

Preferably, the supports and said at least one traverse are provided by a hollow profile, the external cross section and the internal cross section of the prop and the at least one traverse with the traverse and support cross sections designed identical to one another being identical. The term "external cross-section" is understood to mean the external shape of the traverse or the traverse, and the term "internal cross-section" is understood to mean the cross-sectional shape of the cavity.

Preferably, the outer cross section and/or the inner cross section each have a rectangular, in particular square shape.

Preferably, the traverse cross-section of the first traverse is the same as the support cross-section and the traverse cross-section of the second traverse is different from the support cross-section. The cross sections of the two trusses are therefore different from one another.

The lower traverse, here the first traverse, is subjected to compression by the mounted sanitary item and the upper traverse, here the second traverse, is subjected to tensile stress. The different training results in the advantage that each traverse can be optimally designed with regard to its load.

The support and the at least one traverse with the cross-sections of the traverse and support designed to be identical to one another are preferably provided by a square tube, in particular a welded square tube.

A square tube has the advantage that the forces arising from the sanitary item can be easily introduced into the assembly device.

The wall thickness of the at least one traverse and the supports is preferably between 1 and 8 millimeters, in particular between 1.5 and 3 millimeters.

Preferably, the width and/or the height of the cross-section of the traverse of the at least one traverse and of the cross-section of the support of the respective support is in the range of 30 to 50 millimeters, in particular between 35 and 45 millimeters. The width and the height are the expansion dimensions of the at least one traverse or the support seen in a direction transverse to the central axis.

The second traverse preferably comprises at least one fastening element, via which the sanitary article can be fastened to the mounting device. The at least one fastening element is preferably used to hold a threaded rod, which protrudes essentially perpendicularly to the frame and the support and can be brought into contact with the sanitary article. The fastening element has a corresponding internal thread for receiving the threaded rod.

Preferably, the front surface of the supports spans a front plane and the rear Surface of the supports on a rear plane, wherein the at least one traverse is arranged such that it lies between the front plane and the rear plane. In particular, the traverse with the cross section equal to the cross section of the support is arranged such that it lies between the front plane and the rear plane. Other traverses can also penetrate the back plane and/or the front plane.

The supports and the traverses are preferably made of steel.

Preferably, the two supports are identical to each other. In particular, the two supports have the same cross section.

Preferably, the two traverses are each firmly connected to the supports at the ends via a welded connection.

Each of the supports is preferably connected to a footrest, via which footrest the assembly device stands up on a floor, the footrest preferably being designed to be displaceable relative to the support and lockable to the support.

Preferably, the supports are connected to a third cross member in addition to said cross members, which third cross member is preferably arranged at the upper end of the support.

According to a method for producing an assembly device according to the above description, the supports and the traverse, which have the same support or traverse cross section, are produced by a forming process and a subsequent welding process. Due to the same cross-section, the supports and traverses, which each have the same support or traverse cross-section, can be manufactured on the same machine without retooling.

The actual tube cross-section is formed during the forming process and the resulting separation point is also closed during the welding process. A laser welding process is preferably used.

Preferably, before the forming process, for each of the supports and the traverse, which have the same support or traverse cross section, a metal sheet with the dimensions of the development of the profile around the central axis and the profile length provided.

The sheet metal is preferably provided with openings by a punching process before the forming process.

Further embodiments are specified in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the figures, an embodiment of a mounting device 1 for the attachment of at least one sanitary article is shown. The mounting device 1 is firmly connected to a building and then the sanitary items are attached to the mounting device. The assembly device 1 typically stands behind a pretext. The sanitary articles with which the user has direct interaction are mounted in front of the pre-wall, for example a toilet bowl, a urinal or a washbasin. Sanitary items are mounted behind the pre-wall, with which the user does not need direct access, such as a cistern, water supply pipes and sewage pipes.

The assembly device 1 comprises two spaced-apart supports 2, which each extend along a central axis M2. Furthermore, the supports 2 each have a support cross section Q2. Next includes the assembly device 1 a first traverse 3 and a second traverse 4. The first traverse 3 extends along a central axis M3 and has a traverse cross section Q3. The second traverse 4 extends along a central axis M4 and has a traverse cross section Q4. Both trusses are each end firmly connected to the supports 2 and thus connect the supports 2 to each other. The two traverses 3, 4 are preferably connected to the supports 2 via a welded connection. In the installed position, the supports 2 run vertically and the traverses 3, 4 run horizontally.

The assembly device 1 has an optional third traverse 8 on the upper side. The third traverse 8 is arranged at the ends of the two supports 2 . The traverses 3, 4 and 8 are connected to the supports via welded connections. In the embodiment shown, the second traverse 4 is arranged at a distance from the first traverse 3 and, in the installed position, as shown in the figures, is above the first traverse 3.

The traverse cross section Q3, Q4 of at least one of said traverses 3, 4 is essentially the same as the support cross section Q2. In the embodiment shown, the traverse cross section Q3 of the traverse 3 is designed to be the same as the support cross section Q2, while the traverse cross section Q4 of the second traverse 4 has a different cross section. The third traverse 8 also has a different cross section Q8. In other embodiments it is also conceivable that all traverses also have the same cross section as the supports 2 .

FIG. 2 shows a detailed view of FIG. 1, the detailed view being limited to the connection point 10 between the first cross member 3 and the support 2. From this detailed view it can be clearly seen that the outer cross-section of the support 2 and the outer cross-section of said traverse 3 are each the same.

FIG. 3 shows the sections from FIGS. 4 to 6. From the sectional representations of FIGS. 5 to 6 it can also be seen how the profiles are identical to one another. In the embodiment shown, the traverse 3 and the supports 2 are each designed as a square tube. The two square tubes are identical to each other. In other words, the supports 2 and the traverse 3 are provided by a tubular profile, with the external cross section and the internal cross section of the support 2 and the traverse 3 being the same. It is therefore an identical profile. The sectional representations of FIGS. 4 to 6 also show that the wall thickness W of the support 2 is equal to the wall thickness W of the traverse 3 . Typically, the wall thickness of the traverse 3 and the supports 2 is in the range of 1 and 8 millimeters, in particular between 1.5 and 3 millimeters.

The width B and the height H of the traverse cross-section of the traverse 3 and the support cross-section Q2 of the support is in the range from 30 mm to 50 mm, respectively. In the embodiment shown, a square cross-section is shown, that is, the width B and the height H are equal to each other.

As shown in FIGS. 1 and 3, the second traverse 4 comprises at least one fastening element 5. In the embodiment shown, a plurality of fastening elements 5 are arranged. The fastening elements 5 can be designed in various ways. For example, as a threaded opening directly in the second traverse 4, as openings in the second traverse 4, as nuts behind an opening in the second traverse 4, or as a separate fastening part behind an opening in the second traverse 4. The fastening elements 5 are are preferably threaded structures into which the corresponding threaded rods can be inserted or screwed. As already mentioned, the traverse 4 has a different cross-sectional shape.

In the embodiment shown, the traverse 4 is a traverse which is subjected to a tensile load and the traverse 3 is a traverse which is subjected to a compressive load. The different design of the respective traverse means that the traverses can be optimally designed for their mechanical load.

The front surface 6 of the supports 2 spans a front plane F and the rear surface 7 of the supports 2 spans a rear plane R. The at least one traverse 3, 4 is arranged in such a way that it lies between the front plane F and the rear plane R. In the case of the traverse 3, the corresponding side parts of the traverse 3 are also located in the front plane F and in the rear plane R due to the identical design of the supports 2.

Each of the supports is preferably connected to a footrest 11, via which footrest the assembly device stands up on a floor, the footrest preferably being designed to be displaceable relative to the support and lockable to the support. REFERENCE LIST
