Description

[0001] The present invention relates to a punched and / or bent part for fastening a suspended sanitary object, such as a toilet bowl, a urinal or a washstand, or a wash basin, to a pre-wall mounting frame, a punched and / or bent part for fastening water pipes, sewage pipes and / or fittings to a pre-wall mounting frame and a pre-wall mounting frame for a sanitary installation.

[0002] EP 3 995 635 A1 discloses a mounting module for installing a cistern behind a pre-wall element. This mounting module comprises a module frame with vertical struts and transverse struts, the latter connecting the vertical struts to one another. A connecting element can be fastened to the module frame, said connecting element having a first pipe socket and a second pipe socket, the first pipe socket being connectable to a flush pipe connection, and the second pipe socket being connectable to a drain pipe connection. The connecting element is arranged in front of the plane of the vertical struts and the horizontal transverse strut of the module frame. The transverse strut, in turn, is arranged between two vertical struts and does not overlap them.

[0003] DE 20 2015 009 052 U1 describes a mounting device for fastening a sanitary article, comprising a frame supporting the sanitary article, which frame comprises at least two spaced-apart vertical struts, to which a cross member is connected. The mounting frame of the mounting device further comprises a support element that connects the cross member to the vertical struts in order to support the cross member and to transfer the forces resulting from the fastening of the sanitary article from the cross member to the vertical struts. In this known solution, the cross member ends at the lateral surfaces of the vertical struts and is preferably integrally connected to the vertical struts, so that mounting frames are used that already consist of a single unit with vertical struts and a cross member.A force-locking connection between the truss and the vertical struts may be provided for support, but is not explained in detail in the document.

[0004] The object of the present invention is, on the one hand, to provide a stamped and / or bent part for fastening a suspended sanitary object, in particular a toilet bowl, a urinal or a washstand, or a wash basin, to a pre-wall mounting frame, which provides the user with variable options for quickly and securely fastening one or more suspended sanitary objects in different areas of the pre-wall mounting frame.

[0005] The solution to the above-mentioned problem is provided by a stamped and / or bent part having the features of claim 1 or, according to a variant of the invention, having the features of claim 5. The solution variants described in these claims can also be combined with one another.

[0006] It is a further object of the present invention to provide a pre-wall mounting frame which, compared to those known from the prior art, enables simpler and faster assembly, as well as providing the user with variable options for rapid and secure fastening of one or more suspended sanitary items, if necessary including the necessary water and sewage pipes and / or fittings in different areas of the pre-wall mounting frame.

[0007] The solution to this problem is provided by a pre-wall mounting frame for a sanitary installation having the features of claim 8.

[0008] The punched and / or bent part, which according to a first variant is intended for fastening a suspended sanitary object, in particular a toilet bowl, a urinal, or a washbasin, to a pre-wall mounting frame, comprises a rectangular base plate with a first opening, which is optionally provided for the passage of a drain pipe, and a second opening arranged above the first opening, which is optionally provided for the passage of an inlet pipe. The punched and bent part is characterized in that the base plate has an L-shaped angled leg on each of its two lateral edges, via which the punched and / or bent part can be connected, preferably in a tilt-proof manner, to the vertically extending mounting rails of a pre-wall mounting frame.

[0009] According to a further variant, a punched and / or bent part is proposed which is intended for fastening a sanitary object to be mounted in a suspended manner, in particular a washbasin, to a pre-wall mounting frame, comprising a rectangular base plate with two slotted openings spaced laterally apart from one another, via which the sanitary object can be fixed in position with the punched and / or bent part in the mounted state of the punched and / or bent part, wherein the punched and / or bent part is characterized in that the base plate comprises an L-shaped angled leg on each of its two lateral edges, via which the punched and / or bent part can be connected, preferably in a tilt-proof manner, to the vertically running mounting rails of the pre-wall mounting frame.

[0010] Since the L-shaped angled legs of the punched and / or bent part virtually overlap the vertically aligned mounting rails during installation, the solution according to the invention has, among other things, the advantage of universal applicability for use with pre-wall mounting frames from different manufacturers with different rail systems, which may have different dimensions.

[0011] Further advantageous embodiments of the invention are specified in the dependent claims. The features listed individually in the dependent claims can be combined with one another in a technologically expedient manner and can define further embodiments of the invention. Furthermore, the features specified in the claims are further specified and explained in the description, where further preferred embodiments of the invention are presented.

[0012] According to a preferred embodiment of the invention, the base plate of the stamped and / or bent part has two fastening elements arranged at a distance from one another at a height between the two openings. The fastening elements are selected from the group comprising a rivet nut, threaded hole, threaded bushing, or weld-on nut. Thus, the user is provided with various fastening elements on the stamped and / or bent part, which can be adapted to the specific installation situation of the sanitary item to be attached.

[0013] Preferably, each of the two L-shaped, angled legs has at least one connecting means, in particular a button-like connecting means, for connection to a vertically extending mounting rail. Such a connecting means is advantageous because it can absorb higher forces during the attachment of the sanitary article, thus eliminating the need for additional support, as is sometimes used in the prior art.

[0014] According to a preferred development of the invention, the punched and / or bent part further comprises a pipe clamp connectable to the base plate or to a leg extending perpendicularly from the base plate, via which a drainpipe can be fixed in position when the punched and / or bent part is assembled. When assembling a sanitary fixture, such as a toilet, it is advantageous for the installer if a pipe clamp for attaching a drainpipe is already present on the punched and / or bent part, thus predetermining its position relative to the sanitary fixture. This also allows for faster installation.

[0015] Further advantages arise if, according to a further development of the present invention, a further stamped and / or bent part can be attached to the wall-mounted mounting frame, which is specifically suitable for attaching another suspended sanitary item, in particular the washbasin, to the wall-mounted mounting frame. According to this variant, for example, a toilet or urinal can be attached to one location and a washbasin to another location on a single wall-mounted mounting frame.

[0016] It is particularly advantageous if, according to a further development of the invention, a further punched and / or bent part is provided which is specifically designed for fastening water and sewage pipes and / or fittings to a pre-wall mounting frame and which comprises a rectangular base plate which has a vertically angled leg on each of its two lateral edges, via which leg the punched and / or bent part can be connected, preferably in a tilt-proof manner, to the vertically running mounting rails of the pre-wall mounting frame, wherein the base plate in this punched and / or bent part comprises a pre-punched tab provided with an opening on its lower longitudinal side. This tab makes it possible to attach a sewage connection line.In this variant of the invention, it is advantageous if this additional punched and / or bent part is attached, for example, to the pre-wall mounting frame below the previously described punched and / or bent part, which is specifically designed for the installation of a washbasin. In this case, the wastewater connection line can be attached in a defined position to the same pre-wall frame, for which only the additional punched and / or bent part is required, the width of which can be selected according to the respective distance between two adjacent vertically aligned mounting rails of the pre-wall mounting frame, whereby the vertically angled legs on the lateral edges of the punched and / or bent part can then be conveniently attached, for example, screwed, to the vertically aligned mounting rails.

[0017] In the variant of the invention described above, for example, one or more, for example four, laterally spaced holes can be located on the base plate of the punched and / or bent part above the tab (in the installed state), which can be designed to receive fastening elements for fixing a water connection line.

[0018] The present invention further relates to a pre-wall mounting frame for a sanitary installation, comprising at least one U-shaped vertical and at least one U-shaped horizontal mounting rail, in which according to the invention the outer legs of at least one of the U-shaped mounting rails are folded inwards by an offset in an end region, so that the outer legs of the other mounting rail can be engaged behind one another in a perpendicular arrangement.In this variant of the present invention, the assembly of the pre-wall mounting frame is simplified in that, for example, the end regions with the offset of one or more vertically aligned mounting rails of the mounting frame are received between the outer legs of a horizontal mounting rail, resulting in a type of positive connection of these mutually perpendicularly aligned mounting rails, which can then be connected to one another in this receiving region via suitable fastening means.

[0019] An advantageous optional development of the present invention provides that in the previously described pre-wall mounting frame, the offset is designed such that a partial area or a partial section of each outer leg of the U-profile of the mounting rail which lies inside in the connection area with a mounting rail oriented orthogonally to this, which can be either a vertically or a horizontally oriented mounting rail, is separated at its connecting edge to the web of the U-profile in the axial direction, ie along the axial extent of the U-profile, or is folded or drawn in perpendicular to the connecting edge of the leg-web.This makes it possible for the end area of ​​a mounting rail, for example a U-shaped mounting rail, to lie between the outer legs of a second mounting rail, which is arranged orthogonally to it and is also U-shaped in profile, for example, in the assembled state, whereby a positive connection between two mounting rails arranged at right angles to each other and, when using connecting elements, also a force connection between them is possible.

[0020] Alternatively, the offset in the previously described pre-wall mounting frame can be designed such that a partial area or a partial section of each outer leg of the corresponding U-profile is folded / drawn inwards along its connecting edge to the web of the U-profile in the axial direction, ie along the axial extent of the U-profile, or is separated perpendicular to the connecting edge of the leg and web.

[0021] Preferably, in the pre-wall mounting frame according to the invention, the respective outer sides of the two outer legs, which are arranged perpendicular to each other and optionally connected via a force-locking and / or form-locking connection, form a flush support surface. In this context, it is particularly preferred that the offset then corresponds at least to the material thickness of the outer legs of the non-edged mounting rail.

[0022] The present invention further relates to a pre-wall mounting frame for a sanitary installation, in particular a pre-wall mounting frame as described above, comprising at least one U-shaped vertical and at least one U-shaped horizontal mounting rail, preferably with the features described above, in which, according to the invention, the pre-wall mounting frame comprises at least one (first) punched and / or bent part with the features described above for fastening a sanitary object to be mounted in a suspended manner, in particular a toilet bowl, a urinal or a washbasin, to the pre-wall mounting frame, and / or the pre-wall mounting frame further comprises at least one (further) punched and / or bent part with the features described above for fastening a sanitary object to be mounted in a suspended manner, in particular a washbasin, to the pre-wall mounting frame,and / or the pre-wall mounting frame comprises at least one (further) punched and / or bent part with the features described above for fastening water, sewage pipes and / or fittings to the pre-wall mounting frame.

[0024] First, the Fig. 1, which illustrates a first exemplary embodiment of the present invention in more detail. The perspective view according to Fig. 1 shows an exemplary embodiment of the present invention, in which a stamped and / or bent part 10 for fastening a suspended sanitary object, in particular a toilet bowl, a urinal, or a washbasin, is attached to a pre-wall mounting frame 11. It should be noted that the presently shown pre-wall mounting frame 10 is shown only as an example with respect to the stamped and / or bent part 10, as well as the further embodiments thereof, so that such a part is also compatible with other pre-wall mounting frames.

[0025] In the embodiment shown here, the pre-wall mounting frame 11 comprises a plurality of vertical mounting rails 12, 13, 14, 15, 16, 17, for example, U-shaped in profile, which can be set up parallel and at a distance from one another and which, at their lower ends, each engage in a lower U-shaped horizontal mounting rail 18 (floor rail), in which the U-shape is open at the top. The pre-wall mounting frame 11 further comprises an upper U-shaped horizontal mounting rail 19, to which the vertical mounting rails 11, 12, 13, 14, 15, 16, 17 of the pre-wall mounting frame 11 are each connected at their upper ends, wherein the U-shape of this upper horizontal mounting rail 19 is open at the bottom.

[0026] As can be seen from the illustration of Fig. 1, the punched and / or bent part 10 designed according to a first embodiment variant is arranged between the two vertical mounting rails 13, 14 of the pre-wall mounting frame 11, which is shown in detail in the Fig. 5 to 11. This punched and / or bent part 10 comprises a rectangular base plate 20 with a first opening 21, which is provided for the passage of a drain pipe, and a second opening 22, which is arranged above the first opening 21 in the installed state and is provided for the passage of an inlet pipe, wherein the base plate 20 comprises on each of its two lateral edges an L-shaped angled leg 23, 24, via which the punched and / or bent part 10 can be connected to the vertically running mounting rails 13, 14 of the pre-wall mounting frame 11.

[0027] The base plate 20 of the punched and / or bent part 10 has two fastening elements 25 arranged at a distance from one another at a height between the two openings 21, 22, wherein these fastening elements 25 can be, for example, rivet nuts, threaded holes, threaded bushings, weld nuts or the like.

[0028] Each of the two L-shaped angled legs 23, 24 has at least one, preferably several connecting means 26, which can be button-shaped, for example. These connecting means, which protrude on the outside of the L-shaped angled legs 23, 24 (see Fig. 7), the punched and / or bent part 10 can be hung in corresponding receptacles (not shown) in the vertical mounting rails 13, 14 of the pre-wall mounting frame 11, as shown in the Fig. 2. Furthermore, the L-shaped angled legs 23, 24 preferably have several bores 27 (see Fig. 5 and Fig. 6), so that a force-locking connection with the vertical mounting rails 13, 14 can be additionally established via fastening elements, such as screws in particular.

[0029] The punched and / or bent part 10 further comprises a pipe clamp 29 connectable to the base plate 20 or to a leg 28a extending perpendicularly from the base plate 20 or to a lower bevel 28a, via which a drain pipe can be fixed in position when the punched and / or bent part 10 is assembled. Furthermore, the punched and / or bent part 10 can also have a rectangular bevel 28b on the upper edge of the base plate 20, which also serves to stiffen the punched and / or bent part 10.

[0030] It is again pointed out that Fig. 1 to 4, from which it can be seen that, in addition to or as an alternative to the punched and / or bent part 10 described above, a further punched and / or bent part 30 can be attached to the pre-wall mounting frame 11, which is provided for fastening a suspended sanitary object, in particular a washbasin, to the pre-wall mounting frame 11. The fastening of this further punched and / or bent part 30 can be carried out in a similar way to that described above for the first punched and / or bent part 10, on two mutually parallel and spaced-apart vertically aligned mounting rails 15, 16 of the pre-wall mounting frame 11. This further punched and / or bent part 30 is shown as an individual part in the Fig. 12 to 16 shown.

[0031] As can be seen from the illustration in the Fig. 12 to 16, this further punched and / or bent part 30 also comprises a rectangular base plate 31 with laterally arranged L-shaped angled legs 32, 33, via which the punched and / or bent part 30 can be connected to the vertically extending mounting rails 15, 16 of the pre-wall mounting frame 11. In this embodiment, too, each of the two L-shaped angled legs 32, 33 comprises at least one connecting means 26, which, as in the previously mentioned embodiment, can be button-shaped. Furthermore, this punched and / or bent part 30 comprises two laterally spaced-apart slotted openings 34, via which the sanitary object can be fixed in position with the punched and / or bent part 30 when it is in the assembled state.The additional punched and / or bent part 30 can further have an upper rectangular bevel 35 on the upper edge (longitudinal edge) of the base plate 31 and / or a lower rectangular bevel 36 on the lower edge of the base plate 31, which also serves to stiffen the punched and / or bent part 30. Furthermore, holes 37 can also be provided on laterally arranged L-shaped angled legs 32, 33 for further fixation to the mounting rails 15, 16.

[0032] It is again pointed out that Fig. 2 to 4, from which it can be seen that, in addition to the previously described punched and / or bent parts 10 and 30, a third punched and / or bent part 38 can be attached to the pre-wall mounting frame 11, which can be used, for example, for fastening water pipes, sewage pipes and / or fittings to the pre-wall mounting frame 11. This third punched and / or bent part 38 can also be attached to two spaced-apart and parallel, vertically aligned mounting rails 15, 16, in spatial proximity to the further punched and / or bent part 30, for example, below or above it, as shown in the Fig. 2 and Fig. 3, in order to attach or fix waste water connection pipes where, for example, a washbasin is attached to the pre-wall mounting frame 11. This third punched and / or bent part 38 is shown in the Fig. 17 to 21 in several detailed views. It comprises a rectangular base plate 39, which comprises a vertically angled leg 40, 41 on each of its two lateral edges, via which the third punched and / or bent part 38 can be connected to the vertically extending mounting rails 15, 16 of the pre-wall mounting frame 11, for example via a screw connection. For this purpose, the third punched and / or bent part 38 comprises one or more bores 42 in the vertically angled legs 40, 41. Furthermore, the punched and / or bent part 38 comprises a pre-punched tab 44 provided with an opening 43 on the lower longitudinal side of the base plate 39. From the detailed views according to the Fig. 17, Fig. 18 and Fig. 21 it can be seen that in the third punched and / or bent part 38 the base plate 39 has four further holes 45 spaced laterally apart from one another above the pre-punched tab 44.

[0033] Below we will again refer to the Fig. 1 to 4. In the exemplary embodiment shown there, the pre-wall mounting frame 11 according to the invention for a sanitary installation comprises vertical mounting rails 12, 13, 14, 15, 16, 17 with a U-shaped cross-section, a lower horizontal mounting rail 18 with a U-shaped cross-section, in which the U-profile is open at the top, and an upper horizontal mounting rail 19 with a U-shaped cross-section, in which the U-profile is open at the bottom.

[0034] Due to the U-profile shape, the lower horizontal mounting rail 18 has two parallel, in the mounted position according to the Fig. 1 and Fig. 2 vertically upwardly projecting outer legs 18 a, 18 b, which are connected to each other by the U-shaped web of the U-profile. Accordingly, the upper horizontal mounting rail 19 has two parallel, downwardly projecting outer legs 19 a, 19 b in the mounted position, which are connected to each other by the U-shaped web of the U-profile. Furthermore, the Fig. 1 to 4 that the pre-wall mounting frame 11 has further elements 46 for fixing to a wall 46 a or to a floor 46 b.

[0035] As can also be seen from the illustrations, the outer legs of one or more of the U-shaped vertical mounting rails 12, 13, 14, 15, 16, 17 are each folded inwards by an offset in an end region, so that the respective lower ends of these vertical mounting rails 12, 13, 14, 15, 16, 17 engage in the upwardly open U-profile of the lower horizontal mounting rail 18 and the respective upper ends of these vertical mounting rails 12, 13, 14, 15, 16, 17 engage in the downwardly open U-profile of the upper horizontal mounting rail 19 and are received between the outer legs 18 a, 18 b, 19 a, 19 b of the respective mounting rail 18, 19.

[0036] Fig. 22 shows an enlarged detailed view of a section in the connection area between the upper end of the vertically aligned mounting rail 12 and the upper horizontal mounting rail 19. As can be seen from the illustration, the vertical mounting rail 12, which is folded inwards by an offset 48 in an end area 47, can engage in the downwardly open U-profile of the upper horizontal mounting rail 19 and be received between the outer legs 19 a, 19 b of the latter.

[0037] Based on the Fig. 22 also shows that the vertically aligned mounting rail 12 has two recesses 43 in its upper end region between the folded outer legs 45 and the web 44, so that the end web section is designed in the form of a tongue 44. These recesses 43 enable the surfaces 45, which are perpendicular to the web 44, to be folded inwards to form the offset. Furthermore, in Fig. 22, that the inwardly folded surfaces 45, which have the offset, rest with their outer surfaces on the inner surfaces of the two legs 17 a, 17 b of the downwardly open U-profile of the upper horizontal mounting rail 17.

[0038] In the embodiment variant shown here, the offset 48 is designed such that a partial area or a partial section of each outer leg 12 a, 12 b of the mounting rail 12 is separated at its connecting edge to the web 12 c in the axial direction, ie along the axial extent of the mounting rail 12, or is folded or drawn in perpendicular to the connecting edge of the outer leg and web.

[0039] The following refers to the Fig. 23, which is one of the Fig. 22 shows an alternative variant, but the same effect is achieved, namely that the U-profile of the vertical mounting rail 12 is narrower in the end region 47 and can therefore be accommodated between the two legs 19 a, 19 b of the upper horizontal mounting rail 19. Also in the variant of Fig. 23, the vertical mounting rail 12 consists of a U-profile, the two legs 12 a, 12 b of which are bent inwards by an offset 48 in the end region 47, so that surfaces offset inwards are produced. In comparison to the Fig. However, in the embodiment shown in Fig. 22, the edging is designed differently, since the edging takes place along the connecting edge 49 between web 12 c and each outer leg 12 a, 12 b, wherein the offset, then further inwardly located surface is separated from the material of the outer leg located below the end region.

[0040] The two examples of the Fig. 22 and Fig. 23 show that the section of the folded legs 12 a, 12 b of the vertically aligned mounting rail 12 forming the end region 47 can be arranged either vertically (see Fig. 23) or horizontally (see Fig.22) can be folded inwards by an offset 48 relative to its axial extent (longitudinal direction of the vertical mounting rail 12). Preferably, the offset 48 corresponds at least to the material thickness of the outer legs 19 a, 19 b of the non-folded upper horizontal mounting rail 19 or its outer legs 19 a, 19 b, so that the respective outer surfaces of the two mounting rails 12, 13, 14, 15, 16, 17, 18, 19 arranged at right angles to one another then form a flush contact surface.
