Description

Floor pan with substructure

The present invention relates to a floor pan with a tub body which has a thin-walled plastic material.

DE 41 41 334 C2 discloses a tub produced in a deep-drawing process. The tubs used are a sanitary acrylic, which must be supported with a glass fiber reinforced plastic coating on the outer surface. The application of the reinforcement layer made of GRP is complex, must be carried out under conditioned conditions and is time-consuming due to the curing time of the material used. In addition, the different materials can hardly be separated from each other when the tub is disposed of later.

The object of the present invention is to enable the construction of a particularly light tub body with plastic, which does not require an applied reinforcing layer.

This object is achieved with a floor pan with the features of claim 1. Advantageous further developments and refinements are specified in the respective subclaims.

A floor pan according to the invention with a tub body, which has a thin-walled plastic material, and with a trough opening, which is delimited by a circumferential tub rim, to which side walls adjoin, which merge into a tub floor, is supported at least in the region of the tub floor of the tub body and is stabilized by a shell-shaped support body covering the outside of the tub base, which additionally covers the transition area between the tub bottom and side walls. The support body is adapted to the outer contour of the tub floor and the transition area to stabilize the same. The term floor pan includes both floor tubs in the strict sense and shower trays or shower trays.

The tub body preferably consists of a plastic material without an external reinforcement coating

Preferably, the tub body has a substructure on its bottom for the direct support of the bottom tub to the base of the bottom tub. The substructure protrudes laterally above the bottom of the tub body and supports a transition from an essentially horizontally extending tub area to an essentially vertically extending tub area. In particular, the substructure not only runs along the bottom of the tub body, but is also pulled up piece by piece at the lateral edges. The substructure supports the transition from the floor to a side tub area of the tub body. However, the substructure is preferably limited to supporting the transition from the side without, however, additionally supporting the entire side area.

According to one embodiment, the substructure extends over the entire floor of the tub body. This enables a uniform force absorption and support of the bottom of the tub body.

A further development provides that the substructure is arranged such that it can be shifted in height. The adjustable height allows the tub body to be supported extremely precisely above the substructure on the substructure, particularly when assembling the floor pan. In particular, if the surface has slight unevenness or the tub body should not be completely true to size, the height of the substructure can be compensated for. In particular, there is the possibility that the substructure has several adjustment options over its length. In particular, this allows the length of the substructure to be adapted to different dimensional accuracy. One embodiment provides that the company terbau is designed to be flexible in itself, for example by segments that can be moved against one another or by using flexible material.

The tub body is preferably deep-drawn. This enables fast production, which is particularly true to size.

A thick board which has a plastic, in particular a sanitary acrylic, is preferably used to produce the tub body. For example, the tub body is made of an acrylic material. A so-called sanitary acrylic is preferably used, which is poured between polished glass plates to produce the circuit board. In this way, an extremely smooth surface can be achieved. In particular, the material used has properties as defined in the E263 standard for the material of the tub body to be used. The acrylic preferably has a quality as specified in the RAL-G2 705/1 and / or RAL-GZ 705/2 quality classes. A thickness of the board is preferably between 4 to 12 mm.

It is also possible to use a circuit board that has several plastic materials. For example, the board can consist of coextruded sheets. The coextruded sheets can be single or multi-colored. The coextruded sheets can preferably have different thicknesses. For example, the circuit board can consist of a two-layer plate material. One of the plates is thicker than the other. In particular, the thicker plate can have a proportion of 60 to 85% of the total thickness of the plate. For example, the thicker plate is made of ABS, the thinner plate is made of PMMA.

A further development provides that the circuit board consists entirely of a plastic material without this having additional reinforcements such as fiber additions or the like. Preferably, a board is used, the one Has thickness between 8 and 12 mm, in particular about 10 mm. This is deep-drawn, for example, so that the actual tub body is created. When a trough is formed, and thus the trough opening of the tub body, the material of the board is stretched. The use of a support body, which supports not only the bottom of the tub body but also at least the transition from the horizontally extending tub body area to the substantially vertically extending tub body area, makes it possible to manage with a wall thickness that is between 3 mm and 5.5 mm, preferably between 4 mm and 5 mm. According to a further development, this tub body has no further reinforcement apart from the support body. The support body, in turn, is able to absorb the forces impinging on the tub body during operation and at the same time the tub body in particular in critical

To give sufficient stability to places like the transition. In this way it is possible to arrange the tub body in a dimensionally stable manner in the floor pan.

According to a further embodiment, it is provided that the tub body is cast. A plastic can be used as the casting material. A shape is preferably used which has the geometry of the finished tub body, taking into account any shrinking dimensions. The use of the support body, which in addition to supporting the bottom of the

Trough body gives the transition of the trough body sufficient stability, makes it possible to keep the trough thickness small even when the trough body is cast. The cast tub body, for example, has a wall thickness of 3 to 5 mm in the transition, while it has a different material thickness in the lateral tub body area or in the bottom of the tub body.

According to a further development, the tub body is made entirely of plastic without the tub body being formed from metal. According to one embodiment of the floor pan, it is provided that the substructure is a shell-shaped support body, the shape of which is adapted to the tub body in the floor area and to the transition into the vertically extending tub body area. The use of a shell-shaped support body in particular allows it to be produced from a material which is less expensive than that which the tub body has.

The support body preferably has a plastic. In particular, the support body is made of plastic. According to a further development, the support body has a plastic mixed with filling and / or reinforcing material, and preferably consists of it.

In particular, the support body is such that it receives and supports the entire bottom of the tub body as well as the transition from the substantially horizontally extending tub body area to the substantially vertically extending tub body area, but without extending over the entire vertically extending tub body area. Rather, the support body extends only briefly over the transition. The support body itself can have reinforcements, for example by using ribs for stiffening. The material used for the support body can also be fiber-reinforced or have corresponding reinforcement layers on its outer wall.

According to one embodiment it is provided that the support body sits on a support frame. This enables, for example, that the support frame supports, for example, an upper edge region of the tub body directly or indirectly and at the same time forms a support for the support body and thus for the bottom of the tub body. The support frame has, for example, one or more height adjustments and / or horizontal adjustments in order to align the bottom of the tub body and the support body. Preferably he the support frame allows the upper edge region of the tub body to be aligned with the base of the floor tub in interaction with the bottom of the tub body. For this purpose, for example, the supporting frame can be moved on its own. Such mobility can be achieved using set screws or the like. The support body is preferably seated on one or more cross members of the support frame. The support frame preferably has at least three feet which are connected to one another via the crosspieces. The crossbars in turn are preferably adjustable in length and can preferably be adjusted in height on the support frame. For example, the support frame can provide a displaceability that allows the crossbars to be adjusted in their height relative to the ground.

A further development provides that a compressive stress can be generated between the tub body and the support frame, which prevails between the shell and the supporting tub area. For example, this compressive stress can be generated by the tub body and / or by the support frame. In particular, this allows the tub body to be tensioned in the support body. This prevents damage to one or the other from occurring due to the relative movement between the support body and the tub body. Tensioning also enables the dimensional stability of at least part of the tub body to be increased.

According to a further embodiment it is provided that the support body sits on the ground. The substructure preferably consists only of the support body. In this way, a particularly simple construction of the floor pan can be made possible. Preferably, the bottom of the tub body, as well as the transition between the horizontal tub body area and the vertically extending tub body area, sits in the support body, while an upper edge area of the tub body is held in shape-retaining manner, for example, by means of a support frame or other supporting means. Preferably the support body is connected to the ground via a leveling means. The leveling means can, for example, be a compensation layer for adapting height differences.

The support body preferably has a plastic. In particular, the support body is made of plastic. However, the support body can also be made of, for example, wood or another material that has stability. There is also the possibility that the support body consists of a composite material or of different materials in different areas. According to a first embodiment, the support body is an injection molded part. According to another embodiment, the support body is a pressed part. There is also the possibility that the support body has been machined to produce a geometry adapted to the region of the tub body to be supported. For example, the support body can be made from a solid material, into which the geometry of the tub body to be supported is introduced with exact dimensions.

The support body is preferably in one piece. This allows in particular that the support body can be produced in one operation. According to a further embodiment, it is provided that the support body has at least two partial shells. The two partial shells can be put together as a support body before the tub is assembled. There is also the possibility that the partial shells are first assembled to form the support body during the assembly of the tub. This enables, for example, that the area of the tub body to be supported is braced by the assembly of the partial shells. Furthermore, the assembly of partial shells enables inaccuracies to be compensated for, for example, due to unevenness in the surface. A further development provides that the shell consists of partial shells that are clamped together. In this way it is possible for the partial shells to are movably arranged. This makes it possible, for example, to be able to adapt the support body to the respective tub body as precisely as possible.

It is preferably provided that a compensating layer is arranged between the tub body and the substructure. The leveling layer is particularly able to ensure dimensional accuracy between the substructure and the tub body. The compensation layer preferably has a resilient material, is preferably flexible and can be pressed together. According to a further development, the compensation layer can also harden and thus assume a dimensionally stable geometry. For example, the compensation layer can be a foam layer. A closed-pore foam is preferred, especially when using a transparent tub body. One embodiment provides that the compensating splint is inserted as a mat. For example, a mat made of polyurethane is used.

When using a support body, for example, the compensation layer is inserted before the support body comes into contact with the tub body. By pressing the tub body into the support body and at the same time compressing the compensation layer, it is ensured that a uniform contact and power transmission is ensured. The

Use of a compensating layer enables, for example, the support body to have a slight excess compared to the tub body. This avoids the need for complex adjustments to be made on site when the tub is assembled when undersize occurs.

Furthermore, the use of a compensating layer enables this to bring about an adhesive connection between the outer surface of the trough bottom and the support body. A further development provides that the compensating layer has a color which at least approximately corresponds to the color of the material of the tub body, at least on its surface facing the tub floor. For example, the leveling layer is colored. This is preferred, for example, if the material of the tub body is translucent. In one example, a polymethyl methacrylate (PMMA) is used for the tub body. The material is thinned out by the deep-drawing process and becomes translucent in some areas, for example. By coordinating the colors, shining through, for example, a dark color through the tub body can be avoided.

According to another embodiment, the translucent property of the tub body is used in a deliberate manner. In this way, the tub body can be at least partially equipped with one or more color effects and / or light effects. For this purpose, the compensation layer can also have one or more colors.

A further development provides that the tub is equipped with at least one lamp. A plurality of illuminants are preferably arranged. These can be spotlights as well as illuminant strips. The lamps are particularly aligned so that a tub interior can be illuminated. For this purpose, the inside of the tub can be illuminated directly or indirectly. In particular, when using a translucent tub body, the illuminant can be arranged, for example, in the support frame or in a pedestal and / or also in a support.

Support body, compensation layer and tub body can be pre-assembled. This allows the use of appropriately adapted tools in the area of production. This is particularly preferred when the tub body is braced over the support body. This prefabricated tub is then secured with a transport lock. On construction The transport lock can be removed from the location of the tray and the tray can be attached and connected in its position. Before being transported, the tub preferably already has the necessary fittings for the further connection.

According to a preferred development, the support body extends beyond the transition area between the tub floor and the side wall, but without reaching to the tub rim. The support body preferably extends at most up to half the height of the side wall, in particular only up to one third of the height of the side wall. The support body preferably extends only a few centimeters beyond the transition region, preferably less than 10 centimeters, in particular less than 5 centimeters. He can also finish with this.

A further embodiment provides that a sealing profile _t, in particular a sealing lip, runs along the tub body. This prevents moisture from penetrating into a subspace below the tub, to which the tub body is sealed off. The partitioning can take place, for example, by means of a wooden frame or by means of wooden planking, which forms a receptacle for the tub. The sealing profile preferably has a thermoplastic elastomer, preferably it consists of a thermoplastic elastomer (TPE). In particular, the TPE has a Shore hardness A in a range between 20 and 95. The TPE can be based on amide, ester, olefin, styrene or urethane. The more elastic properties are adjusted either by copolymerizing hard and soft blocks or by blending a thermoplastic matrix with a (partially) cross-linked or non-cross-linked rubber. In combination with the geometry of the density profile, this makes it easy to assemble while at the same time being sufficiently resistant to mechanical and thermal loads. Further advantageous refinements and developments are given in the following drawing. However, the configurations and features shown there are not limited to the individual examples. Rather, these can be combined with others, in particular those described above, to form further developments of the invention. Show it:

1 shows a floor pan 1 with a pan body 2. The pan body 2 is supported in an upper region 3 of the pan body 2 by a vertical strut 4 of a support frame 5. For this purpose, the upper region 3 has a U-shape, into which the vertical strut 4 can engage. The floor pan 1 has a first side panel 6 and a further side panel 7. The side panels β, 7 are at least partially removable in order to allow access at least to the supporting part 5. The support frame 5 has feet 8. The feet 8 are preferably arranged movably on the support frame 5 and can be adjusted in height by twisting them relative to the respective vertical strut 4. The vertical struts 4 are connected to one another via one or more cross struts 9. The cross struts 9 form a support surface for a shell 10. A support body 10 receives a bottom 11 of the tub body 2. The base 11 is thereby supported on the support body 10 and in this way maintains dimensional stability. A transition 12 between a horizontally extending tub body region 13 and a vertically running tub body region 14 is likewise arranged in the support body 10 and is supported there. The horizontally extending tub body area 13 forms the bottom 11 of the tub body 2. The vertically extending tub body area 14 forms a side wall of the floor tub 1. The tub body 2 can be connected to the support frame 5, for example, at the upper area 3 via fastening means 15. Preferably the fastening means 15 are adjustable in height. Because of the fastening, it is possible to achieve a bracing of the tub body 2 in the support body 10 by adjusting the height of the feet 8 and / or the fastening means 15. In this way, a dimensional stability of the floor pan 1 is increased.

FIG. 2 shows the floor pan 1 from FIG. 1 with the support body 10. However, in this case the support frame 5 has no cross struts. Rather, the support body 10 has a shell attachment 16. The support body 10 and the shell attachment 16 form the substructure 17, which rests on the base 18 of the floor pan 1. The shell attachment 16 can be made of the same material as the support body 10. In particular, the support body 10 and the shell attachment 16 can be connected to one another in one piece. There is also the possibility that the Sσhalenaufsats 16 is in one or more parts.

Fig. 3 shows the floor pan 1 with a support body 10 which is arranged adjustable in height. The support body 10 is seated on a central part 19. Height adjustments 20 are arranged between the middle part and the base 18. The height adjustments 20 can be feet as well as strips that can be moved. A compensating layer 21 is arranged between the bottom 11 of the tub body 2 and the support body 10. The bottom 11, which is arranged over the entire surface in the support body 10, presses on the compensating layer 21. This in particular enables a precise fit between the bottom 11, the transition 12 and the support body 10 to be achieved.

FIG. 4 shows the floor pan 1 with a multi-part support body 10. The support body 10 has a base 21. The pedestal 21 connects the bottom 11 of the tub body 2 to the base 18. A side boundary 22 of the support body 10, on the other hand, supports the transition 12 as well as part of the vertically extending tub body region 14. The side boundary 22 is fastened to the base 21. The- This can be done for example by gluing as well as screwing or the like.

5 shows an embodiment of the support body 10. The support body 10 has a depression 23, as a result of which a trough opening is formed. The trough 23 is adapted to the tub body to be received, so that not only a bottom of the tub body but also its transition can rest and be supported. The support body 10 has sufficient stability to be able to absorb the forces imposed on the tub body and to transmit it to a surface without causing undesirable deformations of the tub body. The support body 10 is able to ensure that the tub body is adequately supported, particularly in areas as thin as material.

Fig. 6 shows a tub 1 in a top view. The tub body 2 consists, for example, of a translucent material. As a result, the support body 10 can also be seen in a top view through the tub body 2. An outflow opening 24 is let into the center of the tub body 2. This can also be arranged off-center. The tub body is equipped with a slope, in particular in its base area, so that the liquid contained in the tub 1 drains off through the outlet opening 24.

Fig. 7 shows the tub 1 of Fig. 6 along the section VII-VII. The tub body 2 sits on the shell-shaped support body 10. This in turn is held in the support frame 5. The support body 10 preferably has a shoulder 25, via which it can be positioned and held in the support frame 5. According to this embodiment, the tub 1 has a free-standing tub body 2, which is not surrounded by lateral side panels. According to this embodiment, the tub body 2 is, for example, self-supporting and receives its support via the support body 10 and the support frame 5. In order to achieve stability, in particular in the In this area, the upper area of the tub body 2 has a stiffening formed by the geometry of the tub body 2, for example in the form of a crank 26.

FIG. 8 shows the tub 1 from FIG. 6 along a section VIII-VIII. The support frame 5 can, for example, as shown in this view, protrude laterally over the tub body 2. The support frame 5 can protrude beyond the tub body 2 on one, several or even on all sides. A drain 26 is also connected to the tub body 2. As shown, the tub 1 together with the drain 26 can be preassembled and arranged and shipped in a transport lock. 8 also shows a height H, which indicates the distance from the tub floor to the height of the support body along the tub body 2. The height H is preferably designed so that it extends approximately up to a support surface 27 of the support frame 5. This enables the support body 10 to close with the support surface 27. Furthermore, the support body 10 can have the shoulder 25 with a width B, which is in particular between 15 and 30 mm.

Fig. 9 shows a tub 1 with a tub body 2, which rests in the support body 10 with its bottom. The tub body 2 is additionally supported by means of supports 28. The supports are in particular columnar, but can also be rectangular, in particular square in cross section. At least one support 28 is preferably provided on each side of the tub 1. A further embodiment provides that there is no support 28 on the two transverse sides, while two, three or more supports 28 are arranged on the two long sides of the tub body 2. The supports 28 are preferably arranged in the immediate vicinity of the transition from the long side to the transverse side of the tub body 2. FIG. 10 shows a section through the trough 1 from FIG. 9 along the section plane XX. The supports 28 sit on the support frame 5. However, they can also be arranged to the side of it. The supports 28 make it possible to support the base 18 for the area of the tub body 2 that projects beyond the tub floor. The tub body 2 has a support surface for the supports 28. The support surface can be flat as well as curved. It is adapted to a shape of the support 28. The support 28 can have a plastic, a metal or also wood. The support 28 is preferably at least predominantly made of wood, in particular from a piece of wood. The supports 28 have a width that does not form a side cladding of the tub body 2. The tub body 2 is thus arranged in the installed state above the support body 10, visible inside and outside in the room.

According to a further development, the tub 1 preferably has lighting that enables an illumination of an outer wall 29 of the tub body 2. For example, the tub 1 has illuminants 30. The illuminants 30 can be spotlights, in particular halogen spotlights. The use of LEDs is also possible. Such lamps can be arranged in the trough 1 at points as well as continuously, for example in the form of a light strip. The illuminants 30 can illuminate the outer wall 29 directly as well as indirectly. The illuminants 30 can be arranged, for example, in a base region of the tub 1, the base region preferably being formed by part of the support frame 5. Light sources 30 can alternatively or additionally be present in the support 28. This enables the interior of the tub 1 to be illuminated. The illuminants 30 can be distributed uniformly as well as unevenly on the floor area. In particular, they can also have changing colors. The tub body 2 is preferably made of a translucent plastic material. The tub body 2 is, for example, clearly transparent. It can also be colored be one or more colors. In addition, effect agents can be contained in the tub body 2, which provide special light effects, for example, when lighting.

FIG. 11 shows a section along the section plane XI-XI through the tub 1 from FIG. 9. The tub body 2 is supported by the supports 28 and the support frame with respect to the base 18. The drain 26 is arranged on the tub body 2. The support frame 5 preferably has a removable area, in particular a side area, so that a

Access to drain 26 is enabled. The trough 1 is seated on a pedestal 31 by means of the supports 28. The pedestal 31 is preferably at least partially formed by the supporting frame 5. In particular, the platform 31 is designed in such a way that it has the same lateral extent with the tub body 2 and at least on one side, as can be seen, for example, from FIG. 9 for all four sides. The platform 31 preferably has a wood material as the outer appearance. The platform 31 can for example also extend laterally at least on one side beyond the tub body 2, either over the entire side or only over a part of this side. In this way, a storage area can be formed from the subsurface 18, as can a step, for example. This lateral extension beyond the tub body 2 can be formed in one piece with the platform 31 or as one or more additional components which are adapted to the platform 31.

FIG. 12 shows a section of a tub 1 with a tub body 2, a compensating layer 21 and a supporting frame 5. The tub 1 can be provided in a self-supporting manner without further supports as well as with supports 28 according to FIG. 9, for example. 12 that the compensating layer 21 forms a seal. The compensating layer 21 preferably projects beyond the support body 10 and, by sealing off from the tub body 2 and the base region of the support frame 5, prevents moisture from penetrating into it an interior formed by the support frame 5 and the tub body 2. As shown, the shoulder 25 of the support body 10 lies completely on the support frame 5. However, the shoulder 25 can also be recessed into the supporting frame 5 in steps, so that the shoulder 25 and the supporting frame 5 have a surface that merges with one another in this area. The tub body 2 is preferably deep-drawn and therefore has different material thicknesses. In particular, a bottom 11 of the tub body 2, like the transition 12, is equipped with a smaller wall thickness than an upper region of the tub body 2. Furthermore, FIG. 12 shows that the support body 10 is guided along the transition 12 to such an extent that a sufficient stabilization of the bottom area of the tub body 2 takes place. The stabilization is supported by the compensation layer 21. For example, as shown, the compensation layer 21 can also partially merge into the vertically extending tub body region 14, while the support body ends in a transition region between the vertically extending tub body region 14 and the transition 12.

13 shows a further embodiment of a tub 1 with a tub body 2, a compensation layer 21, a support body 10, a support 28 and a support frame

5. The support 28 is provided, for example, with a hollow area 32. The hollow area 31 extends in particular through the support 28. For example, a tie rod 33 is arranged in the hollow area 32. The tie rod 33 enables the trough body 2 to be braced with the support body 10 by exerting a compressive force which can be set, for example, by means of a screw connection 34. If the compensating layer 21 is compressible, so much force can be applied via the tie rod 33 that the tub body 2 is arranged firmly and immovably in the tub and the tub 1 can be transported to a set-up location in a transport lock in such a pre-assembled manner. 14 shows a schematic view of an embodiment of a trough 1 which has a support body 10 in the form of a reinforcing layer. Before the support body 10 is applied, for example, a base region 35 of the tub 1 is coated. The coating is preferably an application of paint. The paint application can be applied, for example, as a varnish or in the form of a gel coat. A dark color, in particular a black color, is preferably used. Instead of coloring the base area 35, the support body 10 can also have a paint application and / or be colored. Preferably, only the floor area 35 is provided with a paint application, which is located within a substructure, not shown. The area of the tub 1 projecting beyond this has, for example, a different color. A reinforcement 36, in particular a plate 37, is also applied to the base area 35 of the support body 10. According to one embodiment, the plate 37 is made of a stable material which enables screws to be fastened. On the plate 37 is a subframe 38 on which one or more feet 39 are attached. However, the feet 39 can also be applied directly to the plate 37. The plate 37 is preferably made of wood and is also attached when the support body 10 is attached. The support body 10 is preferably a GRP coating, as a result of which the plate 37 can also be laminated. The feet 39 are adjustable. This allows their height to be matched to the respective floor. The feet 39 can have an elastic region as shown. This allows adaptation to a floor covering. In addition to height adjustment, the feet 39 can preferably also have an inclination adjustment. For example, a foot 39 can be mounted in a joint, in particular a ball joint, or the foot 39 can be inclined so that it can be locked on the subframe 38. The subframe 38 is preferably constructed such that a foot 39 can be fastened not only in one position but also in another position. The subframe is preferably made of metal, in particular of a stainless metal. It can have a hollow profile. In addition to the support body 10, the tub 1 also has an overflow which is arranged on the side of the tub 1. The overflow has a connection to the drain, which runs in particular as a line 40 visible from the outside. In addition to being directly at the overflow, the line 40 is preferably arranged at least in one section, in particular along a predominant length, at a distance from a tub wall 41. This prevents chafing between the tub and the pipe.

FIG. 15 shows a longitudinal section in a schematic view through the tub 1 from FIG. 14. The feet 39 sit on the base 18 and are adjusted in height in such a way that they remove most of the load from the tub 1, the water contained in the tub and transfer it to the user via the support body 10 into the ground 10. The support body 10 is enclosed in a substructure 42, which receives a lower load than the feet 39. The substructure 42 preferably closes at least approximately with the support body 10. Here, a sealing profile 43 can be arranged between the tub body 2 and the substructure 42. The sealing profile 43 is preferably colored, either in the color of the paint application on the tub, in particular black, or in another color. In the case of a contrast between the two colors, the latter makes it easier to check that the sealing profile 43 is seated correctly. According to one embodiment, the sealing profile has a thermoplastic elastomer (TPE) as the material.

FIG. 16 shows a cross section in a schematic view through the tub 1 from FIG. 14. The tub 1 is stabilized via the supports 28 as well as via the feet 39 and the support body 10. The line 40, which leads to the drain 26, is arranged in a lateral region. The line 40 can be a metal tube, a plastic tube, in particular a sheathed plastic tube, or another connection for the river be 26. As shown, one or more spacers 44 can additionally be arranged between the line 40 and the tub 1. The line 40 can, however, also lead along the tub 1 in direct contact to the drain 26. The line 40 can also be arranged on an end face of the trough 1. There is also the possibility of providing a plurality of lines 40, preferably one on each side of the tub 1.
