Preferably, the standing surface 6 is arranged to the drain opening 27, that the Standing surface 6 is flush with a lower edge 18 of the drain opening 27. Thus, the standing surface opens via this lower edge 18 in the drain opening.

Preferably, the sanitary installation is a shower, with the tub member 5 then providing a shower tray. The term tray element used herein includes any element on which a user can stand, that is, a trough with peripheral side edges, or a trough in the shape of a metal sheet without circumferential side edges. The user of the shower stands on the standing surface 6 of the tub element 5. The shower water is as bottom water on this floor space 6 and is led away over the area from the shower to drain unit 2. For this purpose, the standing surface 6 with respect to the direction of gravity to the drain unit 2 towards preferably inclined, ie with a slope arranged.

The mounting frame 1 is substantially perpendicular in a room and is arranged behind a wall, not shown here or provides with an optional panels 14 at the same time the wall itself. The panels 14 can be additionally covered with tiles. The trough element 5 extends at an angle to the mounting frame 1 and is located substantially at the level of a lower edge 18 of the drainage channel 4. The mounting frame 1 is formed here as a frame with two vertically extending supports 28 and a horizontally extending support 29. In the lower region, the drainage unit 4 is arranged between the two vertically extending supports 28.

Furthermore, the floor drain system comprises at least one fastening element 7 for fastening the tub element 5 to the mounting frame 2. Consequently, the tub element 5 is fixedly connected to the mounting frame 2 by the at least one fastening element 7. This connection has the advantage that a firm connection between the mounting frame 2 and the tub element 5 can be provided, which ensures that the mounting frame 2 and the tub element 5 can be reproducibly aligned with each other and thus a simple assembly is provided. Next movements and thus stresses between the tub element 5 and mounting frame 2 can be avoided.

The fastening element 7 is preferably designed such that these forces in the Run substantially perpendicular to the direction of gravity S, picking up. In other words, the fastening element 7 thus essentially serves to connect the tub element 5 to the mounting frame. The tub member 5 itself preferably rests on supports, not shown, on the floor, whereby the weight of the user standing on the tub member 5 is supported by these supports. Alternatively, the tub element 5 can also rest directly on the floor.

The at least one fastening element 7 can communicate directly with the mounting frame 2. Alternatively, the fastening element 7 can also be connected to the mounting frame 2 via at least one further element, such as, for example, an adapter plate 12 and / or a panel 14. In other words, a direct connection or an indirect connection between the fastening element 7 and the mounting frame 2 is possible.

The fastening element 7 may be formed mechanically and / or cohesively. Preferably, the fastening element 7 is a screw which provides a mechanical connection between the tub element and the mounting frame 2. Alternatively, the fastening element 7 may also be an adhesive or a sealant.

The tub member 5 preferably comprises at least one mounting flange 8 integrally formed on the tub element 5. The mounting flange 8 serves to fasten the tub element 5 to the mounting frame 2. Consequently, the tub element 5 is connected to the mounting frame 2 via this flange 8. The mounting flange 8 preferably protrudes upwards with respect to the standing surface 6 against the direction of gravity S. This allows good accessibility of the fastening flange 8 in order to mount the tub element 5.

In the present embodiment, two mounting flanges 8 are spaced apart from each other and define a flow passage 19 through which the bottom water can reach the drainage channel 4. In addition, an optional further flange 9 is arranged here between the two fastening flanges 8, which flange extends in the other direction, that is to say from the standing surface in the direction of the force of gravity S. The further flange 9 extends here from a mounting flange 8 to the other Mounting flange 8 and has a greater length than the flow passage 19, so that the ends of the further flange 9 come to lie in the region of the mounting flanges 8. The further flange 9 not only has the effect as Abstützflansch but can also accommodate a sealing element, as will be explained below. The further flange 9 can, as it is in the FIG. 3 can be seen welded to the mounting flanges, the further flange 9 then also has a flow passage 19 corresponding recess must have.

The fastening element 7 preferably has the shape of a screw 7, which projects through the openings 10 in the mounting flanges 8 and engages in a standing with the mounting frame 2 in conjunction thread 11. This thread 11 can either lie directly on the mounting frame 2 or be arranged on said other element. Alternatively, the fastening element 7 may also have the shape of an adhesive.

The further element for the indirect connection between the tub element 5 and the mounting frame 2 preferably has the shape of an adapter plate 12, which is arranged between the mounting frame 2 and the tub element 5. The adapter plate 12 is connected via at least one connecting element 13, such as a screw and / or an adhesive or sealant with the mounting frame 2 in connection and the tub member 5 stands with the adapter plate 12 in connection. Consequently, the adapter plate 12 is fastened to the mounting frame 2 via the connecting element 13, and the tub element 5 is fastened to the mounting frame 2 via the fastening element 7. During assembly, the adapter plate 12 can then be mounted to the mounting frame 2 and then the tub element 5 can be connected to the adapter plate 12. This is the indirect connection.

The adapter plate 12 comprises for the mechanical connection between the tub element 5 and mounting frame 2, the thread 11. Preferably, these are threaded nuts 11, which are in communication with the adapter plate 12. The adapter plate 12 further comprises openings 31 through which the connecting elements 13 can be passed. Preferably, the connecting elements 13 are screws which are then threaded, which are arranged on the mounting frame 2, intervention.

The adapter plate 12 further comprises a flow opening 21, which has substantially the same cross section as the flow passage 19. Further, the adapter plate 12 may also include a bending portion 30, which gives the adapter plate 12 an additional stability.

In addition, between the adapter plate 12 and mounting frame 2, a panel 14 may be arranged. For this purpose, the panels 14 have a multiplicity of openings 15 through which the connecting elements 13 can protrude through, so that they can be connected to the mounting frame 12. The panels 14 also include a flow opening 22, through which the water can be fed to the drainage channel 4. So now that the adapter plate 12 and panels 14 are arranged, the bottom water flows through the flow passage 19 and the two flow openings 21, 22 to the outlet channel 4 of the drain unit. 3

All cross-sections through which the bottom water flows are preferably designed as rectangular cross-sections, which has the advantage that a lower edge 18 can be provided, through which the bottom water can flow. The lower edge 18 of all elements traversed by the bottom water is substantially at the level of the standing surface 6. Consequently, the lower edge 18 of the drain unit 3 is at the level of the standing surface 6. These lower edges 18 are all flush with each other.

Between the adapter plate 12 and the tub member 5, a sealing element 16 is preferably arranged. The sealing element 16 extends on the mounting flanges 8 along the direction S and then over the further flange 9. Consequently, a continuous sealing line, which extends below the flow passage 19.

If the panels 14 is arranged, a further sealing element 20 between the panels and adapter plate 12 is arranged. The sealing element 20 is substantially identical to the sealing element 16 and also forms a continuous sealing line, which extends below the flow passage 19 and the flow opening 21.

In both sealing elements 16, 20, it is advantageous that these are around the Flow passage 19 and extend to the flow opening 21 in the adapter plate 12, so that no water between the adapter plate 12 and tub element 5 or panels 14 can pass.

With respect to the gasket, it has also been found to be advantageous if spacer holding elements 17 are arranged, which creates a fixed distance between the corresponding elements between which the gasket has been arranged. Such spacer elements 17 may be provided, for example, by corrugations or by the attachment of corresponding strips on the adapter plate.

The sealing elements 16, 20 are preferably made of a flexible sealant. Particularly preferred is an elastomeric sealant or a silicone sealant is used, which is applied with a spray gun. This sealant also has an adhesive effect between the individual elements. Consequently, there is thus a mechanical connection via the fastening elements 7 and integral connection via the silicone seal 16, 20. The mechanical connection serves to take over the forces described above and the silicone compound essentially provides a sealing connection. Alternatively, a rubber seal can be used.

In an alternative embodiment, only the sealing element 16 can serve as a fastening element 7, wherein then no mechanical fastening element between the tub element 5 and mounting frame or adapter plate must be present. The sealing element 16 may be formed in this case, for example, as a silicone gasket and provides an adhesive connection between the tub element 5 and adapter plate 12 or between the tub element 5 and mounting frame 2 ready.

The tub member 5 is preferably made of steel enamel or acrylic, while the adapter plate 12 is preferably made of a steel. The mounting frame 2 is also made of steel. The panels 14 may be made of plasterboard.

With the help of FIG. 3 Now, the preferred use of the panels 14 will be explained. The panel 14 comprises a front surface 23 which faces the tub member 5 and a rear surface 24 which rests on the mounting frame 2. The front Surface 23 in this case has a recess 25 in which the adapter plate 12, the mounting flange 8 and the flange 9 are embedded. The recess 25 has a depth which substantially corresponds to the thickness of the elements arranged therein, so that the surface 26 of the mounting flange 8, which faces the standing surface 6, comes to lie flush with the front surface 23. Thus, the front surface 23 and the surface 26 are tileable with tiles. The tiles may then extend over the mounting flanges 8 and the panels 14. Here, the fixed connection of the tub element 5 to the mounting frame 2, to which in turn also the panels 14 is firmly applied, the advantage that movements between the tub element 5 and mounting frame 2 or panels 14 are prevented, which prevents buildup of tension.

Another advantage is that, because of the connection of the tub element 5 and the mounting frame 1 can be dispensed with the arrangement of other specially tailored to the tub element elements. Thus, a standardized execution system 1 can be provided.
