Description

The invention relates to a holder for a basin for wall mounting according to the preamble of claim 1.

The basins are preferably toilet bowls or urinals. The basins can also be basins for other uses. The invention is described below using a toilet bowl, but without intending to impose any restrictions thereto.

Toilet bowls are mounted on walls without any part of the bowl being in contact with the floor. To do this, two support rods, preferably threaded rods, are initially provided on the wall, as well as wall connections for the inlet of flush water and for the outlet of waste water. The vertical and horizontal distances between these four mounting contacts are standardized, so that different toilet bowls can be mounted on different pre-wall installation units from different manufacturers.

For this reason, the height of the toilet bowl to be installed must usually be determined before installing the wall-mounted installation. Subsequent vertical adjustment of the position of the bowl is then not possible or only possible with a high level of installation effort.

The state of the art includes a variably adjustable installation mechanism that is directly connected to the toilet bowl and allows vertical adjustment of the installation position within specified limits. However, this requires a specially designed toilet bowl that provides space for such an installation mechanism.

The WO 2018/055415 A discloses a mounting arrangement for movably mounting a toilet bowl. The arrangement comprises a fixed mounting portion and a movable mounting bracket for receiving the toilet bowl. Movable fluid connections are provided to movably connect the toilet bowl to a fixed fluid source and a fixed drain opening. In particular, space-saving bathroom installations are disclosed in which a toilet bowl can be mounted such that it can be moved from a stowed position to an extended position and vice versa using a rotary movement.

The WO 2011/083396 A discloses a support structure for supporting a sanitary fitting, comprising two upright fastening profiles provided with openings for fastening to a wall, and two cross-beam elements which connect the two fastening profiles to each other.

The republished WO 2019/145568 A discloses a connection device for a toilet bowl, comprising a support arrangement that can be displaceably connected to the toilet bowl, with a first bearing point in which a flush pipe is mounted, and with a second bearing point in which an outlet pipe is mounted. The axial distance between the center axis of the flush pipe and the center axis of the outlet pipe in the support arrangement is fixed. The support arrangement and the toilet bowl can be displaced relative to one another in the direction of an adjustment movement when adjusting the height of the toilet bowl. The flush pipe and the outlet pipe each have at least one compensation section, with which an adjustment offset resulting from the adjustment movement between the support arrangement and the toilet bowl between the flush pipe mounted in the support arrangement and the outlet pipe mounted in the support arrangement and the flush water inlet or waste water outlet arranged on the toilet bowl side can be compensated.

The also republished WO 2019/190442 A2 discloses a connection mechanism that allows the height of a suspended toilet bowl to be adjusted according to the user's preferences and needs. The connection mechanism comprises a bracket that allows the toilet bowl to be installed on the surface of a wall using connection elements of the toilet bowl without the need for any modification to the wall.

The DE 299 14 404 U shows a height-adjustable washbasin that is attached to support strips that are guided vertically on guide strips, with the guide strips being attached to a room wall. The support strips each have a rack-like section to which a gear and a drive motor that can be operated by means of a switch are assigned.

The DE 10 2013 001 798 A shows a support device for a toilet bowl, with a first carrier which has first fastening elements for statically mounting the first carrier on a structure and second fastening elements for attaching a cistern to the first carrier, and with a second carrier which has third fastening elements for attaching the toilet bowl to the second carrier, wherein the second carrier is slidably connected to the first carrier between a first, upper position and a second, lower position spaced therefrom in the direction of gravity, wherein the second carrier can be locked at least in the first, upper position and in the second, lower position. Between the first carrier and the second carrier there is arranged a spring which acts against the direction of gravity, one end of which is connected to the first carrier and the other end of which is connected to the second carrier.

The present invention is based on the technical problem of providing a variably usable holder for a basin, in particular a toilet bowl or urinal, for wall mounting.

The technical problem mentioned above is solved according to the invention by a holder having the features specified in claim 1.

The holder according to the invention comprises a frame, an inlet pipe which has a wall-side connection and a basin-side connection, a drain pipe which has a wall-side connection and a basin-side connection, fastening openings for receiving support rods pre-assembled on the wall, for example fastened in the wall and/or in an installation element, and fastening elements, in particular designed as threaded rods, for fastening the basin to the frame, wherein the inlet pipe can be connected to an inlet installed in a wall and to an inlet of the basin, wherein the drain pipe can be connected to an outlet installed in the wall and to an outlet of the basin, wherein the fastening openings are designed to enable variable wall mounting of the frame in at least two different vertical positions with support rods pre-assembled on the wall and wherein the wall-side connections of the inlet pipe and the drain pipe are vertically adjustable relative to the basin-side connections of the inlet pipe and the drain pipe, and is characterized in that the inlet pipe and the drain pipe have a have a stepped course, each with a wall section, a basin section and an angle section running obliquely between the wall section and the basin section, wherein the respective angle section is formed from separate parts which run at an angle to one another, that the angle sections are divided into two parts, wherein one part of the angle sections is connected in a rotationally fixed manner to the wall section and one part of the angle sections is connected in a rotationally fixed manner to the basin section, that a rotatable flange connection rotatably connects the separate parts of the respective angle section to one another and that the inlet pipe and the outlet pipe are each adjustable by rotation about an axis parallel to the axis of the wall-side connections and the basin-side connections.

The vertical and horizontal distances of the basin-side connections and the two fastening elements correspond to the standardized distances, so that any basin, in particular a toilet bowl or urinal, can be attached to the bracket on the basin side. In the same way, the vertical and horizontal distances of the wall-side connections and the fastening openings, in at least two different vertical positions of the bracket relative to the wall mounting position, correspond to the standardized distances between the support rods, inlet and outlet pre-assembled on the wall and/or in an installation element.

This ensures that a basin, in particular a toilet bowl or urinal, can be mounted on the wall in at least two different vertical positions using the bracket. The model of the basin is not important, as the basin-side connections and fastenings have standardized distances.

This means that even after purchasing a bowl and pre-assembling it on the wall, the vertical position of the installed bowl can be changed without having to spend a lot of time re-assembling the wall. It is also no longer necessary to use a specifically designed toilet bowl with an integrated adjustable bracket.

The design according to the invention consists in that the inlet pipe and the outlet pipe have a stepped course, each with a wall section, a basin section and an angle section running obliquely between the wall section and the basin section, wherein the respective angle section is formed from separate parts which run at an angle to one another, that the angle sections are divided into two parts, wherein one part of the angle sections is connected to the wall section and one part of the angle sections is connected to the basin section in a rotationally fixed manner, that a rotatable flange connection connects the separate parts of the respective angle section rotatably connected to one another and that the inlet pipe and the outlet pipe can each be adjusted by rotating about an axis parallel to the axis of the wall-side connections and the basin-side connections.

Due to the characteristic features of the holder according to the invention, it is possible, as will be explained in more detail below in particular embodiments, to achieve a vertical offset by raising or lowering the basin-side installation of fastening elements as well as the inlet pipe and the outlet pipe within predetermined vertical limits, whereby the wall-side installation of the inlet pipe and the outlet pipe remain aligned with the pipes installed on the wall. The pipe connections described can be freely movable and can be aligned manually.

Preferably, however, a gear can be provided for rotating the inlet pipe and the outlet pipe together. The gear has a rack connected to the frame and the inlet pipe and the outlet pipe are connected to a gear wheel forming at least one pitch circle. If the frame is raised while the wall-side connections of the inlet pipe and the outlet pipe are connected, the angle sections of the inlet pipe and the outlet pipe rotate against each other and enable a relative displacement of the wall-side and basin-side connections against each other.

A further improvement of the transmission is achieved by providing the frame with a first mechanism on the wall side and the first mechanism has receiving openings for receiving the wall-side support rods and receiving openings for receiving the inlet pipe and the drain pipe. Furthermore, the frame can be provided with a second mechanism on the basin side and the second mechanism can carry the basin-side fastening elements and have receiving openings for receiving the wall-side support rods and the inlet pipe and the drain pipe. The two Mimics basically cause the inlet pipe and the outlet pipe as well as the fastening elements to be positioned relative to each other on both the wall and the basin side.

It is further preferred that the receiving openings for the inlet pipe and the outlet pipe have an inner diameter that is slightly larger than the respective outer diameter of the two pipes. The resulting gap allows the two pipes to be mobile relative to the respective facial expressions.

The receiving openings of the first and second mimics for the inlet pipe and the drain pipe each provide a support for the pipes on the wall side and on the basin side during the movement caused by raising or lowering the frame. The support automatically causes the angle sections of the inlet pipe and the drain pipe to twist in the plane of the rotating flange connection and the vertical adjustment takes place without the need for manual readjustment.

Furthermore, the fastening openings can be slot-shaped and extend vertically. The two pre-assembled support rods or threaded rods are first positioned vertically in the fastening openings and then fixed. The basin can then be attached to the support in the vertically adjusted position.

Alternatively, the mounting holes can consist of at least two holes arranged vertically one above the other. This provides a grid of holes that does not allow the bracket to be positioned vertically on the wall, but does make it easier to fix the position.

In the following description of the various embodiments according to the invention, components and elements with the same function and the same mode of operation are provided with the same reference numerals, even if the components and elements in the various embodiments may have differences in their dimensions or shape.

In the Fig. 1 and 2 a first embodiment of a holder 2 for a toilet bowl 4 for wall mounting is shown. The holder 2 has a frame 6 which has a predetermined horizontal construction depth which is required for the subsequent construction of the vertically adjustable elements.

The frame 6 has an inlet pipe 8 and an outlet pipe 10 as well as two fastening openings 12 for receiving wall-mounted support rods 14. Furthermore, two fastening elements in the form of threaded rods 16 are provided for fastening the toilet bowl 4 to the frame 6.

The inlet pipe 8 is connected to an inlet 20 installed in a wall 18 and to an inlet 22 of the basin 4 and the drain pipe 10 is connected to an outlet 24 installed in the wall 18 and to an outlet 26 of the basin 4.

The fastening openings 12 are further designed in such a way that wall mounting of the bracket 6 and thus of the toilet bowl 4 is possible in at least two different vertical positions, which is possible in the two Fig. 1 and 2 is shown.

According to the invention, the wall-side connections of the inlet pipe 8 and the outlet pipe 10 are vertically adjustable relative to the bowl-side connections of the inlet pipe 8 and the outlet pipe 10. This achieves the variability of the vertical position of the toilet bowl 4 relative to the wall.

To compensate for the different vertical positions, the Fig. 1 and 2 In the embodiment shown, at least one flexible hose section 8a and 10a is provided between the wall-side connections and the basin-side connections of the inlet pipe 8 and the outlet pipe 10. This allows the function of the holder 2 and the vertical replacement to be implemented steplessly.

As in the Fig. 1 and 2 As shown, the fastening openings 12 are slot-shaped and extend vertically. This allows the support rods 14 to be positioned at different points in the vertical direction. This allows the entire support 2 to be positioned at different positions in the vertical direction and the toilet bowl can be set up vertically in its mounted position. Fig. 1 a highest vertical positioning of the toilet bowl 4 and Fig. 2 a lowest positioning.

The Fig. 1a and 2a show an embodiment modified from the previous embodiment, wherein the same components are identified by the same reference numerals. In Fig. 1a are in the starting position shown - in contrast to the Fig. 1 - the support rods 14 are arranged at the upper - and not at the lower - end of the fastening openings 12. In the Fig. 2a In the position shown, the support rods 14 are located at the lower end of the fastening openings 12, in contrast to the Fig. 2 , in which the stop at the upper end is shown.

The in Fig. 2a The position shown results in the drain pipe 10 running downwards from the toilet bowl 4, while in Fig. 2d an ascent can be seen. The arrangement according to Fig. 2a has the advantage that the water level inside the toilet bowl does not increase when the toilet bowl is in the Fig. 2a The position shown in Fig. 2 In the position shown, however, the water level inside the toilet bowl rises.

In the Fig. 3 to 6 An embodiment of a holder 2 according to the invention is shown, wherein the same reference numerals designate the same components as in the Fig. 1 and 2 The bracket 2 is in the Fig. 3 to 6 without wall installation (except for the support bars 14) and without a mounted toilet bowl.

In the Fig. 3 to 6 the frame 6, the inlet pipe 8, the drain pipe 10, fastening openings 12, the support rods 14 and the two threaded rods 16 are shown.

In addition, the inlet pipe 8 and the outlet pipe 10 have a stepped course, each with a wall section 8b, 10b, a basin section 8c, 10c and an angle section 8d, 10d running obliquely between the wall section 8b, 10b and the basin section 8c, 10c. The angle sections 8d, 10d are divided into two parts, with one part of the angle sections 8d, 10d being connected to the wall section 8b, 10b and one part of the angle sections 8d, 10d being connected to the Basin section 8c, 10c is connected in a rotationally fixed manner. Furthermore, a rotatable flange connection 8e, 10e connects the separate parts of the angle sections 8d, 10d: The plane of the flange connection 8e, 10e runs essentially perpendicular to the axes of the wall sections 8b, 10b and the basin section 8c, 10c. The inlet pipe 8 and the outlet pipe 10 can thus be adjusted by rotating them about an axis parallel to the axis of the wall-side connections and the basin-side connections.

As in particular Fig. 4 further shows, a gear is provided for the joint rotation of the inlet pipe 8 and the outlet pipe 10. The gear has a rack 30 connected to the frame 6 and the inlet pipe 8 and the outlet pipe 10 are connected to a gear 32, 34 forming at least one pitch circle. The gears 32, 34 are connected to the rack 30 and are driven to a rotary movement by this engagement when the frame 6 is raised or lowered. The rotary movement adjusts the vertical positions of the wall-side connections and the basin-side connections of the inlet pipe 8 and the outlet pipe 10 relative to each other. If the wall-side connections are connected to the (for example in the Fig. 1 and 2 shown) wall-side inlet 20 and the wall-side drain 24, the basin-side connections of the inlet pipe 8 and the drain pipe 10 move vertically up or down.

The Fig. 3 to 5 show a lower or low positioning of the basin-side connections in relation to the wall-side connections. In this setting, the two parts of the angle sections 8d, 10d run essentially in a straight line to each other. In order to achieve a higher or upper position of the basin-side connections, the wall sections 8b, 10b and the basin sections 8c, 10c must each be rotated in opposite directions by 90° or 180°.

In the upper position (after a 180° rotation), the two parts of the angle sections 8d, 10d run essentially in a straight line to each other. In an intermediate position rotated by only 90°, the two parts of the angle sections 8d, 10d run essentially at an angle to each other and form an angled course. This position is in Fig. 6 This also results in a shortening of the distance between the wall sections 8b, 10b and the bowl sections 8c, 10c, which must be taken into account when installing the toilet bowl.

Furthermore, Fig. 3 that the frame 6 is provided with a first mimic 40 on the wall side and that the first mimic 40 has receiving openings 42, 44 for receiving the wall-side support rods 14 and receiving openings 46 and 48 for receiving the inlet pipe 8 and the drain pipe 10. The receiving openings 42, 44 are adapted to the diameter of the support rods 14, while the receiving openings 46 and 48 are each slightly larger than the corresponding outer diameters of the inlet pipe 8 and the drain pipe 10.

Fig. 5 shows again that the frame 6 is provided with a second mimic 50 on the basin side and that the second mimic 50 carries the threaded rods 16 on the basin side and has receiving openings 52 and 54 for receiving the inlet pipe 8 and the drain pipe 10. Here too, the receiving openings 52 and 54 have an inner diameter that is slightly larger than the outer diameter of the inlet pipe 8 and the drain pipe 10.

The two mimics 40 and 50 thus ensure that the relative vertical and horizontal distances between the connections of the inlet pipe 8 and the outlet pipe 10 and support rods 14 or the threaded rods 16 are essentially maintained both on the wall side and on the basin side.

When the inlet pipe 8 and the outlet pipe 10 are attached to the corresponding wall connections, the frame 6 and thus the mimic 50 can be moved vertically on the basin side, so that the inlet pipe 8 and the outlet pipe 10 are rotated by the gear 30, 32 and 34. In this way, the two wall sections 8b and 10b with the wall-side receiving openings 46 and 48 and the basin sections 8c and 10c come into contact with the receiving openings 52 and 54. The resulting abutments then lead to a rotational movement of the parts of the angle sections 8c and 10c around the rotatable flange connection 8e, 10e and thus to a vertical offset of the wall-side and basin-side connections of the pipes 8 and 10. This largely avoids manual adjustment of the raw sections.

As the Fig. 3 to 5 As shown further, the two fastening openings 12 are designed as vertically extending slots so that the support rods 14 can be fixed at any position within the fastening openings 12. For this purpose, screw nuts or - as in Fig. 5 shown - clamping lever 56 with washers 58 may be provided. In this way, the holder 2 can be fixed in its vertical position.
