A foot (113) forms an extension at each bottom tube end (111), and is adjustable for height from a remote point accessible from the room side, typically by a shaft (117) engaging with the foot via a worm wheel, whose shaft forms a screw thread engaging in a nut fixed to the tube bottom end. Alternatively a flexible shaft can be used.

Description

The present invention relates to a device for the installation of a bath or shower tray comprising a support frame with support feet and vertical pipe supports, which supports the bath and apron elements for cladding the tub on the room side, which can be connected to the pipe supports by means of clamps, at least one support pipe having a Support element is provided at the upper end, on which the tub edge is supported.

A device of the aforementioned type is known for example from DE-GM 72 23 901. In this known device, the apron elements serve as room-side cladding of the tub, so that it can also be placed in a finished tiled bathroom, without it being necessary to wall or tiling the tub. However, this known device is primarily intended for the installation of a bathtub of conventional shape. It is therefore a rectangular support frame with four Rohreckpfosten, transverse and longitudinal horizontal tubes and these horizontal tubes and the vertical corner posts sheet metal heart pieces are used, which are screwed together to form a rigid frame. Plastic fittings, which are connected to the upper end of the tubular posts, are inserted into the four corners of the bathtub bead. Plastic clip pieces are screwed onto the aprons for the cladding, which spread when pressed onto the pipe posts and then clasp the pipes.

Based on this prior art, the object of the present invention is to provide a device for installing a bath or shower tray of the type mentioned, which is suitable for the installation of tubs in which at least one side of the tub wall parallel to one Room wall runs, especially for the installation of corner baths.

The solution to this problem is provided by a device according to the invention for the installation of a bath or shower tray of the aforementioned type with the characterizing features of the main claim.

In the device according to the invention it is possible, after the tub has been installed, to support the tub rim in an area which is then no longer accessible, e.g. B. make a corner area of a corner tub from a distance by adjusting a height-adjustable foot element in height and thus adjusts a support tube arranged above this adjustable foot element so that the tub is supported in the difficult to access area of this.

The solution according to the invention can, for. B. in so-called whirlpool tubs application, in which units, such as pumps, pipes, etc. are arranged for the whirlpool under the tub, so that the installer after installing the tub, especially if it is a corner tub , from the room-side area from the corner area of the tub not or only very poorly. The corner area of the tub wall is then supported by the support tube, the lower end of which does not yet have to be supported on the floor during assembly.

According to a preferred development of the task solution according to the invention, an adjustment shaft is provided which engages an adjustment element which is connected to the height-adjustable foot element, the height adjustment of the foot element being effected when the adjustment shaft is actuated. Via the adjusting shaft, the fitter can thus adjust the height of the foot element below the support tube after installing the tub so that there is a good floor support of the support tube and thus of the bathtub rim resting on the support element at the upper end of the support tube. This setting shaft runs preferably below the tub and can optionally be designed such that its end on the room side can be rotated by means of a tool. For example, the setting shaft can have a square there or the like. But you can just as well design the setting shaft so that a rotation without tools is possible by hand, for example, by angling the setting shaft on the room side or providing it with a handle or the like.

Within the scope of the invention, various specific configurations of the device for height adjustment of the foot element from a distance are possible. For example, a worm wheel or the like can be provided which is connected to the height-adjustable foot element and which engages with a section of the adjusting shaft. This worm wheel can have, for example, axially upward fastening elements which overlap the head of a screw, this screw serving as a base element and the thread on the shaft of the screw engaging in a nut which is firmly connected to the lower end of the support tube.

According to an alternative variant, a flexible shaft can also be used as the adjusting element, which shaft is connected to a tubular shaft, which serves as an adjusting shaft and can be operated from the end on the room side. This flexible shaft can, for example, be connected at the end to a coupling piece, which in turn is connected to a height-adjustable foot element which is preferably designed as a screw. In this variant, for example, a nut can be attached to a support tube in the lower end region, the thread of which engages the thread of the shaft of the screw. If one then rotates the coupling piece via the adjusting shaft and the flexible shaft, then the screw, which serves as a foot element, and with the nut, which is connected to the support tube, rotates with it, this causes the support tube to be adjusted in height.

According to a preferred development of the invention, at least one shaft guide is provided for the adjusting shaft, which is preferably located in the vicinity of a vertical pipe support and is connected to a fixed part of the supporting frame of the device if possible.

The support tube, which is arranged in the difficult to access area, preferably the corner area of a corner trough, is connected according to a preferred development of the invention via at least one horizontal connecting tube to at least one further vertical tube support, which is preferably located in the front area of the trough. This further vertical pipe support can also have a support element at its upper end. Apron elements can then be attached to this vertical pipe support for cladding the tub on the room side. As said, there may be several such vertical pipe supports in addition to the aforementioned support pipe. These vertical pipe supports do not have to support themselves on the ground, but can end shortly before the ground and then be connected to the support frame via further horizontal connecting pipes, this support frame then having a plurality of support feet which support the entire device on the ground.

According to a development of the invention, it can be provided that for at least one side of the tub wall, on which it runs parallel to a room wall, in addition to the support by the support frame, a wall bracket can be anchored in the wall with a support element on which the wall-side edge the tub wall rests.

As an alternative to this or at the same time, at least one receiving part can be provided which overlaps the tub rim of the tub and which, for example, has a recess into which an apron holding element can be inserted. This apron holding element can have a groove into which the upper angled end of an apron element for the cladding on the inside of the tub can be inserted. This receiving part can be located at the upper end of a pipe support that supports the tub edge, but it can just as well be located at a different location below the tub edge, where no such pipe support is provided.

If such apron holding elements are used, then they can be formed, for example, like clips with two parallel legs, between which a groove can be formed. An angled upper part of the apron element for the cladding can be inserted into this groove, so that additional fastening elements are not necessary here.

The support frame for the device according to the invention can consist of horizontal cross tubes and horizontal longitudinal tubes and optionally also diagonally extending tubes. The vertical tube supports, which support the tub rim, are connected to these cross tubes and longitudinal tubes in some form to stabilize the support frame. The height of the support feet of the support frame, which are supported on the floor, are generally also adjustable in order to adapt to uneven floors. You can do this e.g. B. Use support feet, the bottom of which include height-adjustable foot elements, and connected to these square tubes through which horizontal cross tubes and longitudinal tubes of the support frame are passed. Furthermore, it is preferred to use articulated supports on the upper end of the square tubes which can be pivoted about horizontal axes and on which the trough base rests, so that one can make adjustments to unevenness and different trough shapes.

Since the tubs are often whirlpool tubs today, it is advantageous that, within the scope of the invention, the installation device is designed such that it enables the apron elements for the room-side covering of the tub to be removed as quickly as possible, in order thereby to have quick access to the To create aggregates of the whirlpool for maintenance and repair without much assembly effort.

The device according to the invention is particularly suitable for the installation of a bathtub or shower tray in which two sides of the tub wall run parallel to a room wall, i.e. a corner tub, the tub wall preferably running in a circular arc on the room side and the inner contour of the tub can be practically arbitrary .

If you also think a wall bracket is required for attaching the tub, then you can use sheet metal parts that are screwed to the wall of the room and support elements that are connected to these sheet metal parts, which are preferably made of plastic and that preferably cover the wall edge of the tub engages behind. Such sheet metal profile parts preferably have a lower leg that comes into contact with the wall of the room and an upper bent leg that engages in the plastic profile.

If this should be necessary, in addition to a wall bracket anchored in the wall, a support element that can be attached in the wall can be provided for relining the tub wall at one or more points. This ensures that the tub edge is aligned horizontally. It is advisable to use a support element with a sufficient width, which can be wider than the support element connected to the aforementioned sheet metal profile part. Such a support element for relining the tub can also be screwed to the wall. It should be emphasized, however, that neither a wall bracket for the tub nor support elements are necessary in the context of the present invention, since with appropriate design of the support frame with tube supports, the tub alone can be supported with sufficient security at several points.

If you provide an additional wall bracket for a corner bath, it is advisable to use at least one anchored wall bracket with a support element for each of the sides that run parallel to the wall of the room and / or for each of these sides of the bath wall to provide a further support element to support the Tub to use.

According to an alternative variant of the invention, it is also possible to provide mounting parts for the fastening of the apron elements on the room side, on which a horizontal section of the tub wall rests and which are connected to the upper end of a pipe support via a screw or bolt connection. These mounting parts can, for example, have a vertical, downward, partially cylindrical section, which encompasses the pipe support over part of its circumference. In this variant, there is a particularly advantageous connection between the room-side section of the tub wall and the vertical pipe supports used there for attaching the room-side cladding. If one uses such a holder part for the connection with the pipe supports, then this can, for. B. have an upper horizontal at the end L-shaped angled down leg on which the tub wall rests and it can be adapted in shape to the shape of the tub edge bent downwards. According to a further variant of the invention, massive spacers can also be used in the room-side section of the tub at least at one point on the underside of the tub rim, adapted to the contour of the tub rim, which are glued in or otherwise fastened.

First, reference is made to FIGS. 1 to 6.

1a and b show a plan view of a corner tub with the device according to the invention for installation, the left half and the right half of the tub being shown. Two of the tub walls, namely the tub wall 35 and the tub wall 36 meet at right angles and each run parallel to a room wall. The tub wall 37 on the room side runs in an arc shape and describes approximately a quarter-circle arc. The inner contour 38 of the tub is irregularly oval with a bulge 39 towards the corner of the room. Each with a small distance from the corner between the straight wall-side tub wall 35 or the tub wall 36 and the arc-shaped room-side tub wall 37, a wall bracket 27 that can be anchored in the wall is provided, as shown in FIG. 2, with a support element 28, which one also in Fig. 1 recognizes where the upper horizontal tub rim 40 has partially broken away.

In Fig. 2 you can see the masonry with wall-side tile 41, with the upper horizontal below the tiling Edge 40 of the tub wall runs, which is anchored to the wall at this point and at a further point (see FIG. 1) via the sheet metal profile part 27 of the wall bracket. The sheet metal profile part 27 is dowelled on the wall using the screw 20 with washer 14. The upper horizontal leg 27b of the sheet-metal profile part, which is shown separately in FIGS. 7a, b, c, is received by a corresponding recess 28a of the support element 28, which is preferably made of plastic. This support element is shown again in itself in FIGS. 8a, 8b. The support element 28 is in turn overlapped and gripped behind by the tub rim 40. The tub edge 40 first has a bend 40a vertically downward and then a further bend 40b which is directed inward at right angles. The support element 28 thus rests on the angled portion 40b and thus rests on the wall side against the part 40a of the tub wall and rests on the upper side on the underside of the horizontal section 40 of the tub wall. The support element thus fits into the space formed by the double-angled tub edge 40, 40a, 40b here, so that there is a positive connection between the tub and the support element 28. Then there is also a positive connection between the support element 28 and the upper leg 27b of the sheet metal profile part 27. On the wall side, the tub is also lined with an elastic support profile 26.

In addition to the two support parts 28 for anchoring the tub to the wall, as can be seen in FIG. 1, the tub is also relined on each wall side of the tub closer to the corner of the room by an additional support element 29. This support element 29 can be seen from the sectional view according to FIG. 3 and can be made of wood, for example. The support element can be anchored in the masonry by means of a screw 24 and dowels. As can be seen, the double-angled edge 40 of the tub rests on this support element 29 with its lower angled portion 40b. The support element is relative, as can be seen on the top view according to FIG. 1 elongated in the horizontal direction and is usually fixed by several screws. Among other things, it also serves to align the upper tub edge horizontally.

In the following, reference is now made to FIGS. 4 and 6. From Fig. 4 it can be seen that at the upper end with the tube support 1, a support member 7 is connected, on which the upper horizontal edge 40 of the tub rests. The tub rim 40 can e.g. be glued to the mounting part 7. The holding part 7 can in turn be connected to this pipe support 1 by screws arranged radially with respect to the pipe support 1. The structure of the holding part 7 is explained in more detail below. Fig. 4 shows that the apron elements 42, 43 are each connected to the pipe supports 1 by clamps 9. These clamps 9 are shown again in FIGS. 11a and 11b of the application. They are connected to the apron elements 42 via screw-in pieces 6, the apron elements 42 in turn being glued to the screw-in pieces 6, as will be explained further below.

A pipe support 1 is again shown in Fig. 13 in the view or in partial section. As can be seen, holes la are provided in the upper area for screwing to the mounting parts 7. At the lower end, a sleeve 1b with an internal thread 1c is welded to the pipe support. A threaded piece 3 can be screwed into the threaded sleeve 1c (see FIG. 4), which in turn is connected at the lower end via a foot piece 4 inserted into the threaded piece 3. By unscrewing the threaded piece 3 from the threaded sleeve 1c to a greater or lesser extent and fixing it by means of the nut 16, the desired heights of the pipe support can be set.
Fig. 6 shows the section through the tub at another location, namely approximately in the middle between the two corner areas. The mounting part 7 shown there, which is connected to the pipe support 2, is constructed in exactly the same way as the mounting part 7 shown in FIG. 4, FIG. 6 showing the Bracket part 7 shows, however, in a representation offset by 90 °. In Fig. 6, the bracket part runs at right angles to the outer contour edge of the tub, while in Fig. 4 the bracket part 7 is arranged parallel to the outer contour edge of the tub (see also plan view Figure 1a / 1b). As can be seen in FIG. 6, the pipe supports 2 can also have an arc or kink, so that a lower skirt element 43 is arranged to spring back relative to the upper skirt element 42. The lower bottom edge of the lower skirt element 43 is sealed off from the floor, for example by silicone. Also in the arrangement according to FIG. 6, at the lower end of the pipe support 2, a threaded piece 3 with a foot piece is screwed into the threaded sleeve 1c of the pipe support.

As can be seen from the top view in FIG. 1 and the sectional view in accordance with FIG. 5, a spacer 8, e.g., at least one location, in the present exemplary embodiment at two locations approximately in the middle between two mounting parts 7 on the underside of the tub wall 40. glued in plastic. In its upper contour, the massive spacer 8 follows the arcuate shape of the tub wall in the transition area between the room-side tub wall and the upper horizontal tub rim 40. This spacer 8 is shown again individually in FIGS. 10a and 10b.

The sheet metal profile part 27 for the wall bracket (see also FIG. 2) is described in more detail below with reference to FIGS. 7a, b, c. This sheet metal profile part 27 has, as can be seen from the sheet metal blank according to FIG. 7c, an elongated hole 27d running vertically in the middle. This elongated hole receives the wood screw 20. The sheet metal profile part 27 is bent so that there are two side walls 27c which are perpendicular to the part in which the elongated hole 27d is located. The sheet metal profile part 27 experiences a greater stiffening. As can be seen from Fig. 7a, the sheet metal profile part 27 is bent at right angles to the horizontal at its upper end Leg 27b. At the part in which the elongated hole 27d is located is a section 27e oriented obliquely forward (to the same side as the horizontal leg 27b), which then at its lower end is inclined rearward by almost 90 ° (opposite the horizontal leg 27b) and bent down to the lower leg 27a. As can be seen from FIG. 2, this leg 27a lies against the wall of the room.

8a and 8b, the plastic profile is shown, which serves as a support element 28. As you can see, this has a recess 28a, which receives the upper horizontal leg 27b of the sheet metal profile part 27. In addition, the support element 28 has an approximately triangular shape in longitudinal section with rounded corners 28b.

The mounting part 7 is shown in more detail in FIGS. 9a and 9b. As you can see, it has a middle leg 7b which, when assembled, lies horizontally and serves as a support for the tub rim (see also FIG. 6). This horizontal leg 7b is adjoined on one side by a beveled part 7c, which in turn is followed by a section 7a connected to it at an obtuse angle and vertically aligned in the assembled state, which, as can be seen from FIG. 9a, is partially cylindrical. This section 7a comprises the upper section of the vertical pipe support 1, 2, the bore 7d serving to receive a screw for the screw connection with the pipe support 1, 2. This screw 13 can be seen in Fig. 6.

10 a, 10 b show the massive spacer 8 in plan view and in longitudinal section.

11a and 11b show the clamp 9, which is clipped onto the pipe supports 1, 2. As can be seen from Fig. 11b, the clamp 9 is connected on its side facing away from the clamping opening with a C-profile 9a, on the back of which a screw bolt 9b is attached. On this Bolt 9b, the hexagon nut 6a of the screw-in piece 6 shown in FIGS. 12a and 12b is screwed on. As can be seen from FIGS. 12a, 12b, the hexagon nut 6a is connected to a disk-shaped slug plate 6b. This slug plate 6b can be glued to the inside of the apron elements 42, 43, as can be seen from FIG. 4.

A further alternative embodiment of a device according to the invention for the installation of a bath tub or shower tray is described in more detail below with reference to FIGS. 14 to 19. Figure 14 shows the top view of a corner trough with a quarter circle outline and a support frame with various vertical pipe supports and horizontal struts. In particular, the support frame comprises a front foot connecting pipe 106 and a rear foot connecting pipe 107, partially parallel to the front, a foot connecting pipe 109 connecting them, which runs parallel to a wall side of the corner trough, two stiffening pipes 110, which are perpendicular to the front foot connecting pipe 106 and the rear foot connecting pipe 107 and run parallel at a distance from one another and finally a middle foot connecting pipe 108, which runs parallel approximately in the middle between the two stiffening pipes 110, but is longer than this and extends to the curved, tub-side rim. The middle foot connection tube 108 is also connected to the foot connection tube 109 at its wall-side end and makes an acute angle of approximately 45 ° with it.

From FIG. 15 it can be seen that the foot connecting pipe 106 is connected approximately in the region of a front corner on the room side to a pipe support 105 which supports the tub rim via a support element 101. The foot connecting pipes 106, 107, 110 are passed through four support feet, each with vertical square pipes 121, which, as can be seen from FIG. 14, are arranged in the corner points of a rectangle. It can be seen from FIG. 15 that these support feet are supported on the floor, preferably for level compensation are adjustable in height. It can be seen from FIG. 16 that the trough is anchored to the square tubes 121 and thus to the support frame by means of tensioning devices 122, but this will not be discussed in more detail here, since this is not the subject of the present invention.

The sectional view in FIG. 16 shows the rear support of the tub edge 100 by the support tube 111, which supports the tub approximately in the rear wall-side corner region. This wall-side corner area of the tub is only very difficult to access during assembly from the curved room-side front of the tub, especially since whirlpool units are often installed under the tub in tubs of this type. For this reason, this support tube 111 is provided at its lower end with a height-adjustable foot element 113, the height of which is adjusted via the setting shaft 117 (see FIG. 16), which extends horizontally almost to the front area on the underside of the tub and is therefore easily accessible. The setting shaft 117 is located in the drawing in FIG. 14 below the central foot connecting tube 108. From FIG. 16 it can be seen that this foot connecting tube 108 is fixedly connected to the lower region of the support tube 111 and that the foot connecting tube 108 is fixed at its other end to a vertical tube support 104 connected is. At the upper end of the support tube 111 there is a support element 103 on which the tub rim 100 widened here rests. During assembly, the foot element 113 designed as a screw, the thread of which engages in the internal thread of the nut 112, which in turn is welded to the lower end of the support tube 111, is initially set so that the worm wheel 115 does not yet lie on the ground. FIG. 17 shows an enlarged detailed view, on the basis of which the height adjustment of the foot element 113 can be better explained in connection with FIGS. 18 and 19. Figure 18 shows the top view of the worm wheel 115 with its housing and the setting shaft 117. Figure 19 is a sectional view from which it can be seen that the setting shaft 117 with its engagement area 117b engages in the teeth of the worm wheel 115. In the middle region, three fastening elements 115a, which are arranged axially on a circular arc and are designed as latching tongues, are integrally formed on the worm wheel 115. These fastening elements 115a include the head 113a of the screw 113, which forms the height-adjustable foot element. At its end on the room side, which, as can be seen from FIG. 16, extends into an easily accessible area which lies just behind the skirt element 125, the adjusting shaft 117 has, for example, a square end 117a which enables operation with a tool. In addition, as can be seen from FIG. 16, the shaft is still guided through a shaft guide 116 in this area near its actuation end. This shaft guide 116 is attached to the horizontal connecting pipe 108. If the adjusting shaft 117 is now rotated, the engagement region 117b of the shaft meshes with the worm wheel 115 and thus rotates the worm wheel, which in turn takes the shaft 113b of the screw 113 with it due to its positive connection to the screw head 113a. As a result, this screw 113, which serves as the base element, can subsequently be adjusted in height from a distance such that there is a firm support for the underside of the housing of the worm wheel 115 on the floor and thus a secure support of the tub rim 100 via the support tube 113 and the support element 103 is.

A further alternative embodiment of a device according to the invention for the installation of a bath tub or shower tray is described in more detail below with reference to FIGS. 20a to 34. 20a and 20b show the top view of a corner trough with a quarter circle outline and a support frame with various vertical tube supports and horizontal struts, the support frame deviating in some points from that according to the embodiment according to FIG. 14, but is largely similar in principle. 20a, 20b also has a front foot connecting tube 206 and a rear foot connecting tube 207 partially parallel to the front.

A foot connection pipe 209 runs parallel to a wall side of the corner trough 200. Between the two foot connection pipes 207 and 206 there are two stiffening pipes 210 which are arranged at right angles to each other and parallel to one another. The further middle foot connection tube 208 also runs here at a 45 ° angle to the foot connection tube 209, but the foot connection tube 208 here runs towards the rear corner of the corner trough and does not extend over the entire depth of the corner trough 200, but at the level of the transverse rear Foot connecting pipe 207 ends. As can be seen from FIG. 22, the middle foot connecting tube 208 is connected to the rear vertical tube support 211, which is located in the rear corner region of the corner trough 220.

From FIGS. 20a, b and 21a, b it can be seen that vertical pipe supports 201, 202 are also present in the two front corners of the tub, which are accommodated at their upper ends in support elements 212 or support elements for the tub edge. In the rear corner area of the tub, where the room walls converge, the upper end of the vertical pipe support 211 is also received by a support element 203 or support element on which the tub rests, as can be seen from FIG. 22. The foot connecting pipes 206, 207 and the stiffening pipes 210 connecting them are passed through four support feet, each with vertical square pipes 221, which, as can be seen from FIGS. 20a, 20b, are in turn arranged in the corner points of a rectangle, similar to the exemplary embodiment according to FIGS 14 and 15. These support feet are supported on the floor, as can be seen from FIGS. 21a, 21b and 22, and are preferably adjustable in height. The trough is anchored to the square tubes 221 and to the support frame via tensioning devices 222, which can be seen in FIG. 22, but which are not explained in detail here.

22 shows the rear support of the edge of the tub 200 in the wall-side corner area via the vertical support tube 211 and the support element 203. Since this wall-side corner area of the tub is in turn difficult to access from the curved room-side front of the tub 200 after it has been installed here also a height-adjustable foot element 213 is provided, the height adjustment of which is possible after the tub has been installed. The mechanism for adjusting the height of the height-adjustable foot element 213 is here somewhat differently than in the embodiment variant according to FIG. 16. At the upper end, the height-adjustable foot element 213 is connected via a coupling piece 214 to a flexible shaft 215, which can be seen in FIG. 23 . This flexible shaft 215 is in turn received by a tubular shaft 217, which extends it axially towards the front of the tub 200. This tubular shaft can be seen in FIG. 22 and in FIG. 20a and in the enlarged detail in FIG. 23. As can be seen, the flexible shaft 215 is pushed a little into the tubular shaft 217. The tubular shaft 217 is angled at right angles to the side at its actuating end 217a (see also FIG. 20a) which can be reached from the front of the trough and is rotatable about its longitudinal axis. When the tubular shaft 217 rotates, the flexible shaft 215 also rotates. This flexible shaft is, as can be seen from FIG. 22, preferably bent upwards and executes approximately a 90 ° bend, so that its other end, which is connected to the coupling piece 214, is oriented downwards. The coupling piece 214 is provided with an internal thread 214a, into which the threaded shaft 213a of the upper part of the foot element 213, which is designed as a type of screw, is screwed. This screw 213a is passed through a nut 214, which is attached to the lower end of the vertical tube support 211. This vertical pipe support 211 does not extend to the bottom, but ends a distance above it. If one now actuates the angled actuating end 217a of the tubular shaft 217 from the front and rotates the tubular shaft 217 about its axis, then the flexible shaft 215 rotates with it and also clutch 214 rotates. This causes a rotation of the screw 213a and thus a height adjustment of the foot element 213 relative to the vertical pipe support 211. It is thus possible to correctly adjust the support in the rear corner area on the support element 203 after the corner trough 200 according to the invention has been installed.

As can be seen from FIG. 20a, the tubular shaft 217 is guided through one or more clamps 216 which have corresponding bores 216a. These clamps are shown again in detail in FIGS. 32 to 34. Such a clamp 216 has a clamping jaw 216b which corresponds to an approximately U-shaped receptacle and is elastic and can be snapped onto the foot connecting tube 209 in the manner of a snap connection. The tubular shaft 217 is fixed and guided via these clamps 216.

The support and support of the edge of the corner trough 200 according to the exemplary embodiment according to FIGS. 21a to 34 will now be explained. From Fig. 21a it can be seen that at the upper end of the vertical pipe supports 201, 202, which are located in the front corners of the tub on the room side, at the upper end there are support elements 212 on which the tub rim rests. The vertical pipe supports 201 are connected to the support frame, e.g. B. welded, but are not supported with their lower end on the floor. The support on the floor takes place, as already explained, via the support frame and the four support feet with the vertical square tubes 221.

The support element 212 is shown in detail again in detail in FIG. 29. This is preferably a plastic part which, as can be seen from FIG. 30, has an angular shape in outline as viewed from above and which has an integrally formed shaft 212b on the underside which engages over the tube support 201, which can be seen in FIG this shaft 212b is inserted with its upper end. In the upper area, the support element 212 is flat and thus forms one Support for the tub rim 224, the angular shape of the support element 212 following the outline of the tub 200 in this front corner area on the room side, as can be seen from FIG. 20b. The support element 224 has an outer, pulled-down edge part 212b, which is positively gripped by the tub edge 224 which is angled downwards and inwards at two right angles. A similar support element 212 is provided in the other front corner area of the tub 200, as shown in FIG. 21a.

From Fig. 22 it can be seen that in the front area of the tub 200, approximately in the middle between the two front corners on the room side, a locking device for the apron element 242 is provided, which is solved here somewhat differently than in the embodiment variants of the invention described above. This lock for the apron element 242 is shown in more detail in FIG. 24. In addition, reference is made to FIG. 20b, from which it can be seen that the receiving parts 219 used for the apron locking are preferably present several times at intervals from one another. These receiving parts 219 are overlapped by the tub rim 224, as can be seen in FIG. 24. Seen in the front view, these receiving parts 219 have the shape of a U which is open towards the bottom, as can be seen from FIG. 26. The tub rim 224 rests on the upper U-bridge 219a. The receiving parts 219 have a recess 219b towards the front. An apron holding element 226 is inserted into this recess 219b, which element is again shown in FIGS. 27 and 28. This apron holding element 226 has approximately the shape and function of a clip and has an upper leg 226a and a lower parallel leg 226b, which is somewhat longer than the upper leg 226a. At its front end, the lower leg 226b is angled perpendicularly downward to the front web 226c. A groove 226d is formed between the two legs 226a and 226b, into which an upper bend 242a of the apron element 242 is inserted. The apron holding element 226 is thus in held the receiving part 219 and in turn holds the apron element 242 via its groove 226d.

For additional fastening of the apron element 242 or the additional lower apron element 243 (see FIG. 22), adhesive plates 227 are used, which are located on clamps 229. These clamps 229 are snapped onto a vertical pipe support 204 by a snap connection. For this purpose, reference is also made to FIG. 31, which shows this detail in an enlarged view. The pipe support 204 is located under the front edge area of the tub 200 approximately in the middle between the pipe supports 201, 202 of the front corner areas.

The connection between the clamp 229 and the adhesive plate 227 comprises a threaded bolt 230 which engages in a threaded bore 231 of the clamp 229. This makes it possible to subsequently change the distance between the clamp 229 and the adhesive plate 227 and thus also the distance between the pipe support 204 and the apron element 242 by screwing the clamp 229 more or less onto the threaded bolt 230.
