The support tube, which in the difficult to access area, preferably corner area of a corner tub is arranged according to a preferred development of the invention at least one horizontal connecting pipe with at least connected to another vertical pipe support, which is preferably in the front area of the tub located. This additional vertical pipe support can be attached to your also have a support element at the upper end. At this vertical pipe support can then be used for apron elements Install the tub cladding on the room side. It can be like said several such vertical pipe supports next to that aforementioned support tube may be present. This vertical Pipe supports don't have to support themselves on the ground, but can end just before the ground and then over more horizontal connecting pipes connected to the support frame be, this support frame then several support feet has, which support the entire device on the ground.

According to a development of the invention, one can provide that for at least one side of the tub wall on which this runs parallel to a room wall, in addition to that Support by the support frame in the wall anchorable wall bracket with a support element is provided on which the wall-side edge of the Tub wall rests.

Alternatively or at the same time you can at least one Provide the receiving part that the tub edge of the tub overlaps and has, for example, a recess, into which an apron holding element can be inserted. This Apron holding element can have a groove in 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 at the top of a pipe support are located, which supports the tub edge, but it can just as well in another place below the Tub edges are where there is no such pipe support is provided.

If you use such apron holding elements, then you can form these, for example, in brackets with two parallel legs, between which a groove is formed can be. An angled upper part can be inserted into this groove of the apron element for the cladding, so that additional fasteners are not necessary here are.

The support frame for the device according to the invention can be made of horizontal cross tubes and horizontal longitudinal tubes and optionally also diagonally running pipes consist. The vertical pipe supports that line the tub rim support, are in with these cross tubes and longitudinal tubes some form connected to the support frame too stabilize. The support feet of the support frame, which are on Ground support is usually inherent to adapt to Uneven floors are also adjustable in height. One can this z. B. Use feet that are on the underside include height-adjustable foot elements, as well as with these connected square tubes, through the horizontal cross tubes and Longitudinal tubes of the support frame are passed through. Further is preferably used at the upper end of the square tubes articulated supports pivotable about horizontal axes which the tub floor rests, so that one can adapt to Can make bumps and different tub shapes.

Since the tubs are often whirlpool tubs today, it is from Advantage that within the scope of the invention, the mounting device is designed that this as quickly as possible Apron elements for cladding the tub on the room side enables quick access to the Aggregates of the whirlpool for maintenance and repair without to create great assembly effort.

The device according to the invention is particularly suitable for the installation of a bathtub or shower tray on two sides the tub wall run parallel to a room wall, so a corner tub, the tub wall facing the room preferably runs in a circular arc and the Inner contour of the tub can be practically any.

If you have an additional for the attachment of the tub Wall bracket considers necessary, then you can do it Use sheet metal profile parts that are screwed to the room wall are connected as well as with these sheet metal profile parts Support elements, which are preferably made of plastic and preferably the wall-side edge of the tub over and engages behind. Such sheet profile parts preferably have a lower leg that comes to rest on the wall of the room and an upper bent leg, which in the Plastic profile engages.

If this should be necessary, one can additionally a wall bracket anchored in the wall another in the Wall mountable support element for relining the Provide the tub wall in one or more places. Thereby a horizontal alignment of the tub edge is achieved. It is recommended to use a support element with sufficient Use width, which may be wider than that connected to the aforementioned sheet metal part Support element. Such a support element for the Relining the tub can also be on the wall be screwed on. But it should be emphasized that in the framework the present invention neither a wall bracket of the tub support elements are still necessary, since one at Appropriate design of the support frame with pipe supports with this alone the tub is sufficient at several points can support safely.

If you have an additional wall bracket for a corner bath provides, it is appropriate, for the pages that run parallel to the room wall, at least one each anchorable wall bracket with a support element and / or one for each of these sides of the tub wall Use support element to reline the tub.

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

1a and b show a plan view of a corner bath, being once the left and the right half of the tub are shown is. Two of the tub walls, namely the tub wall 35 and the Tub wall 36 meet at right angles and run each parallel to a room wall. The room side Tub wall 37 runs in an arc and describes approx. a quarter circle. 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 arcuate trough wall 37 is one each in the wall anchored wall bracket 27 provided as they is shown in Fig. 2 with a support element 28, the can also be seen in Fig. 1, 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 at this point and at another point (see Fig. 1) on the Sheet metal profile part 27 of the wall bracket anchored to the wall is. The sheet metal profile part 27 is via the screw 20 dowelled with a washer 14 on the wall. The upper horizontal leg 27b of the sheet metal section part, which in itself taken again in FIGS. 7a, b, c is shown, is thereby from a corresponding recess 28a preferably plastic support element 28 added. This support element is still in itself shown once in FIGS. 8a, 8b. The support element 28 is in turn overlapped by the tub rim 40 and attacked. The tub rim 40 initially has one Bend 40a vertically down and then another Bend 40b which is directed inwards at right angles. The Support element 28 thus lies on the bend 40b and is therefore on the wall side of part 40a of the tub wall and lies on the top on the bottom of the horizontal Section 40 of the tub wall. So the support element fits into the space that the double angled tub rim 40, 40a, 40b here forms, so that a positive Connection between the tub and the support element 28 results. Between the support element 28 and the upper leg 27b of the Sheet metal profile part 27 then also exists positive-locking connection. The tub is also on the wall side relined by an elastic support profile 26.

In addition to the two support parts 28 for anchoring the wall Tub is as you can see from Fig. 1 also on everyone Wall side of the tub closer to the corner of the room through the tub an additional support element 29 relined. This Support element 29 is from the sectional view according to FIG. 3 recognizable and can consist of wood, for example. The Support element can by a screw 24 and dowels in Masonry to be anchored. As you can see, it is twofold angled edge 40 of the tub with its lower bend 40b on this support element 29. The support element is as can be seen on the top view according to FIG. 1 relatively elongated in the horizontal direction and is usually fixed by several screws. It serves among other things also to align the top edge of the tub horizontally.

In the following, reference is now made to FIGS. 4 and 6. Out Fig. 4 shows that at the upper end with the pipe support 1st a holding part 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 Bracket part 7 can in turn by radially with respect to the Pipe support 1 arranged screws with this pipe support 1 be connected. The structure of the holder part 7 continues explained in more detail below. Fig. 4 now shows that the Apron elements 42, 43 each by means of clamps 9 with the Pipe supports 1 are connected. These clamps 9 are still once shown in Figs. 11a and 11b of the application. she are screwed into pieces 6 with the apron elements 42 connected, the apron elements 42 in turn with the Screw-in pieces 6 are glued as below is explained.

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 screwing the threaded piece 3 out of 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, however, showing the mounting part 7 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, a threaded piece 3 with a foot piece is screwed into the threaded sleeve 1c of the pipe support at the lower end of the pipe support 2.

How to get from the top view Fig. 1 and the sectional view 5 can be seen in at least one place, in present embodiment in two places each in the middle between two bracket parts 7 on the Underside of the tub wall 40 a spacer 8 e.g. out Glued in plastic. The massive spacer 8 follows in its upper contour the arcuate course 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 once again taken in the Figures 10a and 10b shown.

In the following, with reference to FIGS. 7a, b, c Sheet metal profile part 27 for the wall bracket (see also Fig. 2) described in more detail. This sheet profile part 27 has how to the sheet metal blank according to FIG. 7c recognizes one in the middle vertical slot 27d. This slot takes the Wood screw 20 on. The sheet metal profile part 27 is bent so that there are two side walls 27c that are perpendicular to the part in which the slot 27d is located. The Sheet metal profile part 27 experiences greater stiffening. How can be seen from Fig. 7a is the sheet metal profile part 27 on his upper end bent at right angles to the horizontal Leg 27b. At the part in which the elongated hole 27d is located at an angle to the front (at the same Side as the horizontal leg 27b) aligned Section 27e, which is then nearly at its lower end 90 ° backwards (opposite to the horizontal Leg 27b) and bent down to the lower Leg 27a. This leg 27a lies as shown in FIG. 2 can recognize on the room wall.

8a and 8b, the plastic profile is shown, which serves as a support element 28. As you can see, this one a recess 28a which the upper horizontal leg 27b of the sheet metal profile part 27. For the rest, it has Support element 28 in longitudinal section approximately triangular Shape with rounded corners 28b.

The mounting part 7 is closer in FIGS. 9a and 9b shown. As you can see it has a middle leg 7b, which lies horizontally in the assembled state and as a support serves for the tub rim (see also Fig. 6). On this horizontal leg 7b includes one side bevelled part 7c, in turn with this one connected at an obtuse angle and assembled vertically aligned section 7a connecting, how to recognizes from Fig. 9a is partially cylindrical. This section 7a includes the upper portion of the vertical pipe support 1, 2, the bore 7d serves a screw for the Record screw connection with pipe support 1, 2. This Screw 13 can be seen in Fig. 6.

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

11a and 11b show the clamp 9, which on the Pipe supports 1, 2 are clipped on. As can be seen from Fig. 11b recognizes the clamp 9 at its the clamp opening opposite side connected to a C-profile 9a, on the a screw bolt 9b is attached to the rear. On this Bolt 9b, the hexagon nut 6a of the in the Fig. 12a and 12b screwed screw 6 shown. As can be seen from FIGS. 12a, 12b, the hexagon nut is 6a connected to a disk-shaped slug plate 6b. This Patch sheet 6b can be on the inside of the apron elements 42, 43 are stuck on, as can be seen from FIG. 4.

In the following, with reference to FIGS. 14 to 19 the device according to the invention for the installation of a bath or Shower tray described in more detail. Figure 14 shows the top view on a corner tub with a quarter circle outline and a supporting frame with various vertical pipe supports and horizontal ones Struts. In particular, the support frame includes front leg connection tube 106 and a rear, partial to the front parallel, foot connecting pipe 107, this one connecting foot connecting pipe 109, which is parallel to a Wall side of the corner tub runs, two stiffening pipes 110, which are perpendicular to the front foot connecting pipe 106 and rear foot connecting pipe 107 and parallel with a distance run together and finally a medium one Foot connection pipe 108, which is parallel approximately in the middle runs between the two stiffening tubes 110, however is longer than this and extends to the arcuate, extends to the edge of the tub. The middle one Foot connection pipe 108 is also connected to the Foot connecting pipe 109 connected at its wall end and takes an acute angle of about 45 ° with it.

It can be seen from FIG. 15 that the foot connecting tube 106 is approximately in the area of a front corner on the room side with a Pipe support 105 is connected via a support element 101 supports the tub rim. The foot connecting pipes 106, 107, 110 are through four support feet, each with vertical Square tubes 121 passed through, as shown in FIG. 14 removes, are arranged in the corner points of a rectangle. From Figure 15 you can see that these feet are on the ground support, preferably for level compensation are adjustable in height. From Figure 16 it can be seen that the Trough over clamping devices 122 on the square tubes 121 and is thus anchored to the support frame, but what should not be discussed in more detail here as this is not The subject of the present invention is.

The sectional view of Figure 16 shows the rear support of the Tub edge 100 through the support tube 111, which is about in supports the tub at the rear wall-side corner area. This wall-side corner area of the tub is in the assembly of the curved room-side front of the tub only very much difficult to reach, especially since this type of tub often whirlpool units are installed under the tub. For this reason, this support tube 111 is at its lower End with a height-adjustable foot element 113, whose height is adjusted via the setting shaft 117 (see Figure 16), which extends almost to the front area horizontally extends below the tub and is therefore easily accessible. The adjusting shaft 117 lies in the drawing Figure 14 below the middle Foot connecting pipe 108. From Figure 16 it can be seen that this Foot connection tube 108 to the lower portion of the support tube 111 is firmly connected and that the foot connecting pipe 108 its other end with a vertical pipe support 104 connected is. Located at the top of the support tube 111 there is a support element 103 on which the widened here Tub rim 100 rests. When assembling, the first is as Screw trained foot element 113, the thread in the Internal thread of the nut 112 engages, which in turn on lower end of the support tube 111 is welded, initially so set that the worm wheel 115 is not yet on the Ground. Figure 17 shows an enlarged Detailed view, based on which in connection with the figures 18 and 19 the height adjustment of the foot element 113 better can be explained. Figure 18 shows the top view of the Worm gear 115 with its housing and the setting shaft 117. Figure 19 is a sectional view from which one can see can that the adjusting shaft 117 with its engagement area 117b engages in the teeth of the worm wheel 115. in the middle region are three on the worm wheel 115 axially arranged on a circular arc, as locking tongues trained, fasteners 115a formed. This Fasteners 115a include screw head 113a 113, which forms the height-adjustable foot element.

In addition, as in FIG. 16 emerges the wave in that area near her Actuating end still guided by a shaft guide 116. This wave guide 116 is on the horizontal Connection tube 108 attached. Now turn that Adjustment shaft 117, then meshes with the engaging portion 117b Shaft with the worm wheel 115 and turns it Worm wheel, which in turn due to its positive Connection with the screw head 113a of the shaft 113b Takes screw 113. This allows you to use it as a base element serving screw 113 subsequently from a distance in the Adjust the height so that a firm support on the underside of the Housing of the worm wheel 115 on the floor and thus one secure support of the tub rim 100 via the support tube 113 and the support element 103 is given.

In the following, with reference to FIGS. 20a to 34 another alternative embodiment of a Device according to the invention for the installation of a bath or Shower tray described in more detail. 20a and 20b show the Top view of a corner tub with a quarter circle outline and one Support frame with various vertical pipe supports and horizontal struts, with the support frame in some Points from that according to the embodiment of FIG. 14 deviates, but is largely similar in principle. The support frame according to FIGS. 20a, 20b also has front foot connecting tube 206 on and a rear partially to the front parallel foot connecting pipe 207.

A runs parallel to a wall side of the corner trough 200 Foot connection tube 209. Between the two Foot connecting pipes 207 and 206 are two to each arranged at right angles and parallel to each other Stiffening pipes 210 available. The further middle Foot connection tube 208 also runs here at a 45 ° Angle to the foot connecting tube 209, which Foot connection tube 208, however, here on the rear corner of the Corner tub runs up and does not extend over the entire depth of the Corner tub 200 extends, but at the level of the transverse rear foot connecting pipe 207 ends. As can be seen in Fig. 22 recognizes the middle foot connecting tube 208 with the rear vertical tube support 211, which is in the rear Corner area of the corner tub 220 is connected.

From Fig. 20a, b and Fig. 21a, b you can see that in the the two front corners of the tub as well vertical pipe supports 201, 202 are present, respectively their upper ends in support elements 212 or Support elements for the tub edge are included. in the rear corner area of the tub, where the room walls converge, the top end of the vertical pipe support 211 also from a support element 203 or support element on which the tub rests, as can be seen in FIG. 22 recognizes. The foot connecting pipes 206, 207 and these connecting stiffening pipes 210 are by four support feet led through with vertical square tubes 221, which can be seen from FIGS. 20a, 20b, again in the Corner points of a rectangle are arranged, similar to the embodiment of FIGS. 14 and 15. This Support feet are supported, as can be seen in FIGS. 21a, 21b and 22 removes, from the floor and are preferably adjustable in height. The tub is connected to the clamping devices 222 Square tubes 221 and anchored to the support frame that one 22, but this is not explained in detail here become.

22 shows the rear support of the edge of the Tub 200 in the wall-side corner area over the vertical Support tube 211 and the support element 203. Since this wall-side Corner area of the tub after assembly from the curved room-side front of the tub 200 bad is attainable is also a height adjustable one Foot element 213 provided, the height adjustment after the Installation of the tub is possible. The mechanism for that Height adjustment of the height-adjustable foot element 213 is here somewhat differently than in the variant according to Fig. 16. At the upper end is the height adjustable Foot element 213 via a coupling piece 214 with a flexible shaft 215 connected, which can be seen in Fig. 23 can. This flexible shaft 215 is in turn by a Tube shaft 217 added, this axially to the front the tub 200 extended. You can put this tube shaft in 22 and in FIG. 20a as well as in enlarged detail in Fig. 23. As can be seen, flexible shaft 215 is on Pieces inserted into the tubular shaft 217. The tubular shaft 217 is accessible from the front of the tub Actuating end 217a (see also FIG. 20a) at right angles to Angled side and is rotatable about its longitudinal axis. At Rotation of the tubular shaft 217 rotates the flexible shaft 215 With. This flexible shaft is, as can be seen from Fig. 22, preferably bent upwards and performs about one 90 ° bend, so that its other end, that with the Coupling piece 214 is connected, oriented downwards is. The coupling piece 214 has an internal thread 214a provided, in which the threaded shaft 213a as a kind Screw-formed upper part of the foot element 213 is screwed in. This screw 213a is through a nut 214 passed through the bottom of the vertical Pipe support 211 is attached. This vertical pipe support 211 does not extend to the ground, but ends Piece by a distance above this. Now operate from Front of the angled actuating end 217a Tubular shaft 217 and then rotates tubular shaft 217 about its axis with this the flexible shaft 215 and also rotates clutch 214 rotates. This causes one Rotation of the screw 213a and thus a height adjustment of the Foot element 213 relative to the vertical tube support 211. This makes it possible to retrofit after installing the corner bath 200 according to the invention its support in the rear Correctly set the corner area on the support element 203.

As can be seen from Fig. 20a, the tubular shaft 217 is by a or more clamps 216, the corresponding holes 216a have, led. These clamps are again in detail 32 to 34 for themselves. Such Clamp 216 has a clamping mouth 216b, which is approximately U-shaped Recording corresponds and is elastic and in the manner of a Snap connection snapped onto the foot connecting tube 209 can be. A determination and Guidance of the tubular shaft 217 given.

Below is the support and support of the edge the corner tub 200 according to the embodiment of FIGS. 21a to 34 explained. From Fig. 21a it can be seen that on each upper end of the vertical pipe supports 201, 202, the are located in the front corners of the tub facing the room at the upper end there are support elements 212 on which the tub rim lies on. The vertical pipe supports 201 are connected to the support frame, e.g. B. welded, support however, its lower end does not settle on the floor. The support on the ground is done as already explained was, over the support frame and the four feet with the vertical square tubes 221.

The support element 212 is shown again in detail in FIG. 29 shown enlarged. It is preferably about a plastic part, which in plan view as shown in Fig. 30 can recognize, has an angular shape in the outline and that at the Underside has an integrally formed shaft 212b, which the Pipe support 201 overlaps, as you can see, in this Shaft 212b is inserted with its upper end. At the top The area of the support element 212 is flat and thus forms one Support for the tub rim 224, whereby by the angular shape the support element 212 the outline of the tub 200 in this front corner area on the room side follows, as can be seen from FIG. 20b can recognize. The support element 224 has an outer pulled-down edge part 212b, which of the two here angled downwards and inwards Tub rim 224 is positively embraced. In the other front corner area of the tub 200 is like 21a shows a similar support element 212 is provided.

From Fig. 22 it can be seen that in the front region of the tub 200 about halfway between the two front ones corners on the room side for the apron element 242 is provided, which is solved here somewhat differently than in the embodiment variants of the invention described above. in the This detent is for the apron element 242 shown in more detail in Fig. 24. 20b from which it can be seen that the for the Apron lock used receiving parts 219 preferably several times at intervals are. These receiving parts 219 are from the tub edge 224 as can be seen from Fig. 24, overlapped. In the Seen from the front, these receiving parts 219 have the shape a U that is open towards the bottom, as can be seen in FIG. 26 can see. The is on the upper U-bridge 219a Tub rim 224 on. They have to the front Receiving parts 219 a recess 219b. In this recess 219b, an apron holding element 226 is inserted, which for taken again shown in Figs. 27 and 28 is. This apron holding element 226 has approximately the shape and Function of a bracket and has an upper leg 226a and a lower parallel leg 226b that has something is longer than the upper leg 226a. On his front The end of the lower leg 226b is perpendicular downwards angled to the front web 226c. Between the two Legs 226a and 226b have a groove 226d formed therein an upper bend 242a of the skirt member 242 is inserted. The apron holding element 226 is thus in held the receiving part 219 and in turn holds over his Groove 226d the apron element 242.

For additional fastening of the apron element 242 or the supplementary lower apron element 243 (see Fig. 22) adhesive pads 227 are used, which are are located on clamps 229. These clamps 229 will on a vertical pipe support 204 by a snap connection snapped. 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 in a threaded bore 231 of the clamp 229 engages. This makes it possible, if necessary, to also subsequently Distance between the clamp 229 and the adhesive plates 227 and thus also the distance between the pipe support 204 and the apron element 242 by changing the Clamp 229 more or less far on the threaded bolt 230 screwed on.
