DE19847911A1 - Installation of bath tub, comprises fastening pedestal to floor and mounting tub on carrier - Google Patents

Abstract

Installation of bath tub, comprises fastening a tub base pedestal (4) to the floor and mounting the tub. The tub has a carrier (2) complementary to the pedestal. An Independent claim is also included for the corresponding components.

Description

The invention initially relates to a method for installation of one accommodated in a tub support Tub shape, for example a bathtub shape or shower trays shape.

Such methods are already known. Usually is an integrally tensioned tub support, such as. is known from EP-A1 261 521 in a room, übli usually a bathroom in which the tub is installed to be fixed on the floor. Suitable Usually you use an assembly foam. The The tub support is first turned upside down provided the underside with the mounting foam and then turned over before the assembly foam hardens and arranged on the floor in its installation position net. The foam then hardens stable connection.

Tub supports have also been proposed which only come from different parts at the installation location an overall tub support.

For this purpose, EP-A1 15 is, for example, on DE-PS 38 38 753 463 and DE-A1 196 48 361 to refer. The handha Exercise of such tub supports is not always satisfactory presenting. When turning the tub door gers to the arrest in the manner described can cause distortion in the shape or even come apart.

In addition, tub shapes are increasingly used, which have low dimensional accuracy. this concerns especially acrylic trough shapes. There are already expenses  Measures have been taken to ensure that such Trough shapes provide suitable support in the tub support ensure. However, this support can only be used when Inserting the tub made on site or adjusted become.

In view of the state of the art described above the invention deals with the technical Problem, a procedure for installing a wan Specify the carrier that is feasible with rational a good support of the respective tubs form results. This technical problem is first and essentially in the subject matter of claim 1 solved, which is based on the fact that initially a Bath support base in a room such as a bathroom always at the intended location of the tub shape is set up and, if necessary, fastened and that subsequently one already with a the base to a tub support complementary tub support supplement piece Trough shape is placed on the tub support base. According to the invention, the procedure is such that the fixing of the installation location only a tub support base is provided, which is set up or with the floor in attached as described. Only after the tub shape with the connected tub support Er supplement connected to the base. Insertion the tub shape in the tub support on site is omitted Without substitution. Rather, the tub shape is already working inserted into the tub support supplement or connected to the tub support supplement. The fact that the tub shape in the factory Can support support piece is used, can hereby already rationally geach to a good fit be tested. It is also particularly preferred that ex works the tub support supplement  Foaming the tub shape is produced. So that is an immediate concern of the tub support supplement piece on the tub shape ensured that it is on the respective dimensions of the tub shape does not arrive.

The invention also relates to one in a tub sluggishly shaped tub shape such as a bathtub or a shower tray. Suitable tub supports for this are already known in many forms. On the prior art known at the outset is referenced sen. In addition, U.S. Patent No. 4,069,523 is applicable refer from which it is already known, a Tub shape with self-foaming urethane, which around the Tub is poured around. Although through this procedure good adjustment of the tub support to the tubs can be achieved, the handling is possible in installing and installing one tub shape still received in a tub support not satisfactory. Starting from the above The prior art deals with the invention also with the technical problems, one in one Bathtub support shaped like a bathtub or shower tray to indicate, especially with regard Installation easier to handle on site is.

This technical problem is first and foremost Lichen solved in that the tub support parallel to an opening level of the tub is divided into two, wherein a waiter formed as a tub support supplement part is firmly connected to the tub and the lower part as a separate tub support base the tub support supplement can be assembled. The tub support base can therefore with regard to the at first on the floor in the usual way  Local foam can be provided and by hardening the place foam to be attached to the floor. It is a matter of a relatively lightweight part that is easy to do so is to be handled. Then the in the tub support Supplementary tub shape used in simple Be placed on the tub support base, so that a conventional one is housed in a tub support ne tub on site again. In a preferred version staltung is also provided that the upper part form is conclusively connected to the tub shape. This can about by foamed, bent edge areas of the Tub support shape can be achieved. Overall, it can Supplement for tub support by foaming the tubs be formed. A particle is preferred here foam, for example an EPP or an EPS. It is also preferred that the foam around the tub shape leaving an opening in the area of an overflow connection of the tub shape is incomplete. This Recess in the tub support supplement possible light the installation of the overflow pipe later. Ent speaking there is a in the tub support base assigned recess. Laterally, preferably also in an integrally foamed wall of the tub nträger supplementary piece, an assembly opening featured to be seen. The assembly opening can be known in itself ter way through wall thinning in the sense of a target break point must be specified. But it can only superficial ribs or the like can be provided, which specify a cutting area.

The invention then relates to one in a tub bathtub shape, for example a bathtub or a shower tray, in particular to carry out the described procedural steps and proposes to the club Installation times before that the tub support base  has a plurality of lateral openings for connecting pipes. That comes to the variable Use of such tub supports. Here you can practically all sides are equipped accordingly. It is advantageous if the side breakthrough area forming part of the assembly chambers Openings. In this way they form the gate to such Installation centers. It also saves space the measure that the tub support base as a whole is designed as a lattice component. The grating can here limiting the opening or dividing the opening be used. To ensure continuous contact with the ground It is suggested to ensure the tub support base gene that the side openings as from above in the Trough support base recessed grooves are realized. The corresponding edge of the tub support addition The breakthroughs are gradually covered like falls. A monta advantageous solution then consists in that the Tub support base a holder for an overflow pipe having. Such a holder is the subject of not previously published DE 197 51 347.6. The Offenba The content of this application becomes full included, also for the purpose, characteristics of this Documents in claims of the present registration with to record. To a sufficient load-bearing part too the bracket rises above an upper one Connection level of the tub support base, so that also Tub support supplement piece in terms of accommodation and is also involved in terms of management. Next is featured see that the bracket in the area of a foot end of the Trough shape is formed. To the transition between the upper connection level and the attached tub door ger supplement with regard to the form-fitting To continue to establish a stable connection has continued gene that under the tub support supplement  in the longitudinal direction of the tub support walls are trained. In return, the tub support Base the recesses corresponding to the joining strips. Seen in the transverse direction, this can be a hat profile create approximate joints.

The tub support supplement can also be ge forms that it corresponds to that from the beginning known EP A1 261 521 known tub support einsei a sloping wall and a straight wall on the other side having. Accordingly, the slope can also be in continue the tub support base. So on site can be recognized directly on the tub support base, which side the bevel is on. If the sloping surface is to be arranged towards the wall, So the straight wall of the tub support in front of the room is a distance must be entered with respect to the wall will hold which of the total slopes of the eventual composite tub support. Therefor it can be recommended on the tub support base Di to provide the necessary spacing render immediately. In the event that the inclined surface space is arranged on the side, this spacer can abge be broken, for which purpose a suitable shape, for example by means of a predetermined breaking point. With regard on the accessibility to the assembly, it is further favorable, that the recesses are open on one end side, d. H. open into a side surface of the tub support base. This opens up an advantageous sliding assembly. This can, for example, from the narrow side surface of the tub door ger socket are made here. The recess can Have undercut flanks, this in adaptation to a corresponding cross-sectional profile of the associated Jointing board. Such fasteners can Taper assignment direction. This takes one  Sliding connection does not go the full length. Rather, you can about half overlap the two basic components of the tub support supplement and Fix the tub support base with a vertical one Mating step and then leading to the sliding connection dung. Either way, is in the area of the tub foot end trained the slide support base a sliding stop det. This takes into account the desired congruence both connected parts. In terms of construction, the slide can just flip through a side of a pipe recess formed. To access the assembly making a breakthrough even cheaper, it is proposed that assigned to a lateral Opening a side recess in the tub door ger supplementary piece is formed. It can Size that is the dimensions of a revision shaft corresponds. Another contribution to the low The installation requires the most effort Feature that a drain pipe in the tub support base is foamed. This allows an extremely economical che pre-equipment. There is also a cheaper monta technical contribution in that tub support base and tub support supplement piece rastver together are binding. This tube-mounted version is factory-made tig connected. It can even be a crazy one act sible connector. It is proposed here a solution according to application DE 197 53 375.2 (not prepublished). Their solution elements are here also included for the purpose of Merkma le of these documents in claims of the present application to include. Then it's on a tub form, especially a shower tray is advantageous that the breakthroughs equal on four sides forms are. Such a tub support base has especially with a shower tray support a quadrati  floor plan containing a plurality of recesses measures for receiving a siphon. By 90 ° each going over the tub support base can suitable recess should be selected. Around to also use scope in the horizontal, that is To be able to vary the distance to the disposal line, it is further proposed that the recesses on Circles of different diameters with respect to one Center of the tub support base are arranged. Even diameter jumps can be applied here his. It is favorable if one recess consists of two intersecting pot holes is; here too the placement is made in such a way that the intersecting pot holes on a radia len are oriented with respect to the center. Here is on the unrestricted accessibility of the exception respects what is structurally reflected suggests that the tub support base with respect to one middle support area and an edge formation Lowering, from which the recess extend downwards. It is like a ring shaped valley in front, which can be installed as desired is usable, with the support area as a middle pla teau together with the edge wall, i.e. edge formation ensures the inner stability of the tub support base. The all-round lowering, on the other hand, can also be used as can be classified as material-saving.

Continuing education of even independent importance results from particle foam on a tub support fabric, preferably made of EPP or EPS, for example according to Aus education according to one or more of the preceding Claims, characterized in that the tub support a soft foam pad on a floor is, however, by the weight of the tub and  of the tub support, filled if necessary and with user Person prefers no more than half kompri can be mated. Given the surface area, it can here by a twentieth to a third of the reason act on the surface of the tub support. The soft foam Foam pad takes into account the outline of the tub support, here the shower tray. The corresponding The frame structure is also designed like a lattice. The The thickness of the soft foam pad is between 0.3 and 1.5 cm. About this soft foam pad is an effective acoustic decoupling from the underground given.

The invention also applies to a tub support a foam, in particular particle foam, preferably made of EPP or EPS, for shower trays or Bathtubs, with two at an angle to each other side walls forming a corner area, with both assigned side walls a revision Opening can be formed by removing an opening part is in suggestion that by removing one of the Opening area penetrating the corner area in both sides form an inspection opening at the same time is. That opens up a quick, different one Directions possible access to the area surrounding the tub running, for example a final leak test to make or manufacture them. That is an advantage regardless of whether it is already an industri ell completely tubed tub support unit or whether the relevant tub support in handcrafted Piped in the construction. Completely industrial armored units definitely have the advantage of already correctly assembled from home with the right set and an economical one chen. The connection on the disposal side can be made through  the division of the elements forming the tub support In no time at all clear and easily accessible men. After the functional test (through views as through Buttons), the opening part is simply the corner richly assigned. This blocks the optional access away over the two side walls. The corner area to Using the inspection leaves the tub support overall a high stability, since this creates the inspection opening hole per wall is smaller, but overall offers a spatially relatively large shaft. The plug away can be used strictly page-oriented, d. H. one side wall can be through the wall of the Construction must be kept. Accordingly, the opening is Partly implemented as a corner piece. From stabilisa toric reasons, it proves advantageous that the opening part a part of the support of the tub bo forms the surface, d. H. if appropriate puts the tub floor area directly on the public on. It acts as an integrated support part. It is easy to assign if the opening part tapers towards the tub drain. That makes a shaft-like taper with peripheral enlargement Outer insight opening. Also for the wrist and that There is more space available for the joint. It can do so be proceeded that the opening part above and / or underside wedge-like towards the tub drain is tapered. It has a centering effect. At Shower tray supports are preferred to the former version given, as this is the visual inspection despite the deep location the inspection opening easier. It brings further Invention proposed that the greatest thickness of the wedge is reached in the corner line. The corresponding matter Alan accumulation stabilizes the opening part as such and also enables the wedge as a kind "Key" to use, so only intended  related assembly parts the appropriate joining allow. A secure grasping or grasping the opening tion is achieved in that in the outer walls the recessed grip recesses are formed.

On a generic tub support that consists of a Tub support base and a tub support addition piece exists, it also proves structurally as green stig that the opening part, a parting line between Tub support base and tub support supplement comprehensive, both in the tub support supplement piece and also protrudes into the tub support base. The opening part also acts as a locking piece compared to relative displacements of the superimposed / ver bound tub support forming parts. The opening can be part of the tub support already in the way of a kind Assign pre-assembly. This is achieved by the fact that Opening part has side wings that match Entry grooves of the tub support are assigned. Wei ter puts the invention in proposal that the tubs support base and the tub support supplement in vertical direction itself to the height of a usual Supplement tub or shower tray support, i.e. to approx. 555 mm or 305 mm. Especially proven with acrylic tubs it is advantageous that the tub support add tongue in one the support surface for a tub bo the forming area has a higher density. This boundary layer acts like a stable skin, the usage loads in such tubs tolerated. Can be below the higher density range an area of lower density can be realized. Their values are 23 to 30 g / l, while for the Support surface values of 60 g / l are preferred. Selbstre The area of higher density can also change in shape from vertical bars to bathtubs  Continue carrier base. The economy is like that elevated.

On a tub support made of foam, in particular Particle foam, preferably made of EPP or EPS, for Shower trays or bathtubs, it also proves to be advantageous that the tub support from one of the tubs shape-retaining tub support supplement and one trained to accommodate drain piping ten, with a channel recess the tub support addition tubs facing surface carrier base is assigned. The channel recess can as a starting point for another excavation for a Lowering the drain piping can be used. Also can the channel recess for inserting any Additional elements can be used, for example to guide Grounding lines. It is also proposed that the Tub support supplement the rounding of an inlaid ten tray bottom is formed in one piece. An adhesion promoter can be interposed here. Tub and tub support supplement stabilize each other. It also proves to be laying technology useful when inserted in a to hold a lowering formed a support bar runs in a corner shape of the depression. He is can be removed to form a slope. The removal zone is relative small area. The accommodation is then convenient Measure that the lowering in the tub support base on the top through a recess in the tub support Er supplement is supplemented. The tub support supplement piece offers a congruent course of action vault. The lowering is now shared by both support-forming elements. An advantageous one Variant of the tub support then results from that the tub support supplement the tub support  The base is overlaid with a molded apron. It there is such a box-like structure. By the peripheral centering of tubs achieved in this way support base and plugged tub support supplement special directional patrices / matri interventions are eliminated. One also reaches through Sidewalls, if it has continued that the Face of the apron to rest on the floor forms is. The front surface extends at least to short before the floor. It also proves to be favorable that the apron in the area of an inspection opening underneath Chen is. This can take the form of a portal which is so large that it can be removed or assigned of the opening part is not hindered. For tiling the jacket wall of the tub support turns out to be favorable that the apron and corner area are flush on the outside run. In this way, tiles can be tiled without a step.

In the case of a tub support, train on the tub shape ter drain and overflow device with a drain line device, an overflow line and a siphon then advantageous for assembly that the drain and overflow partially in the tub support supplement and is partially arranged in the tub support base, one of the joining areas between the tub support Base and associated with the tub support supplement Interface between these sub-facilities in the course assembling the tub support supplement and Sink support base seals automatically. This is a carrier that is practically completely hidden from view directional coupling of the sub-devices reached. Gear we work in the joining area. The right alignment tion can already be specified at the factory, so that the whole thing after fixing the tub support base on adding the rest of the bathtub superstructure  ne or shower tray limited. The right alignment is possible by adding foam (PU foam), via which the base-side sub-device is fixed becomes; however, one is preferred and convenient to use Solution in such a way that in the tub support base located sub-device in one of the tub door ger base separate mounting part is held. The Receiving part can be on the contour of the to be recorded Partial facility be turned off, so that only in each case type-appropriate sub-facilities can pair nen. With the appropriate basic orientation it proves furthermore advantageous that the receiving part each if it stops in the tub support base borders can be moved in one plane. It can be act as it were a floating assignment that makes even larger deviations compensable. To do this, simply place the tub support on the face placed and the tub support base opened congruently puts. By correcting the recording partly the correct docking of the still reach moving parts in no time. It is further provided that the receiving part out in a chose the right position with the tub drawer ger base is firmly connected. One is preferred Adhesive connection applied. On the one hand to achieve the level-oriented shift, on the other hand to Formation of attachment areas is further from before part that a stepped in the tub support base Opening is formed, in which the reverse step te receiving part is inserted, the engagement step of the receiving part in two mutually perpendicular directions lines one level is shorter than the opening in the tub support base. For those in the longitudinal direction movement of the tub support is oriented used the longer way. To achieve a good wear  the seat between the sub-device and the receiving part it is proposed that the receiving part on the top one formange to a partial area of the partial device has a suitable hollow. Here is both the silhouette recorded as well as the retractable contour of the concerned Partial facility. This is embodied in the use siphon type so that the trough is keyhole tig, the larger circular area being a part of the Interface forming siphon pot. It’s like that well supported. The tub equipment Carrier supplement looks like that in parts included in the tub support supplement direction from one of the tub overflow to the tubs leading first line and one of the wan drain in the direction of the second sub-device leading second line exists. In space-saving green The assignment is proceeded in such a way that the first line runs at an angle adapted to the tub shape and that the second line runs vertically straight. Then there is an advantageous embodiment of even independent meaning in that the second Line a cantilevered connecting section det, being on the tub support supplement pin are formed, and that the connecting portion a has a smaller clearance length than the tenons. The Pins can be attached with a correspondingly base-free attachment of the tub support supplement on the bottom of one Work as a table leg-like spacer, so that it doesn't have a shifting orientation of the connection section comes. Then there is a Vari ante the docking method according to the invention in that the first and second lines separate from each other the sub-device directed connection sections point. This leads to a double docking point at the uses the advantages described above in the same way  are bar, it being further provided that the Sub-device in the corresponding joining partner ent speaking has two connection pots. Here is the Siphon as a partial device in the tub support base forms. The connection pots are in line with each other connected. It turns out coming back to the cones still as advantageous if these consist of separate parts consist. One is so free in the firmness of their structure door. It proves to be advantageous if the Pin made of hard material z. B. best plastic hen. But also a high degree of partial compression of the carrier-side foam is conceivable fend the cone and its root area on the support side.

The procedure is such that in the tubs support base and the tub support supplement piece each because a sub-device of a drain device is arranged. Then a kind of pre-assembly is handled like this have that included in the tub support base Subdivisions at a first assembly of Tub support base and tub support supplement be fixed in position and then indi vidualized parts in a second assembly be finally connected. Finally, this is how it is done ren that the sub-device in the tub support base in a recording part is inserted and that the recording part is fixed in position during the first assembly.

Shown and described is first of all with reference to FIG. 1 a tub shape 1 , which is firmly connected to a tub support supplement 2 by foaming. The tub support supplement 2 has underside projections in the form of pins 3 , for the form-fitting connection with a tub support base 4 according to FIG. 2. In the tub support base 4 , corresponding recesses 5 are formed.

It is also shown, although this is not absolutely necessary for the object specifically described, that the projections 3 and recesses 5 are distributed such that only a clear assignment of the tub support supplement 2 to the tub support base 4 is possible. In view of the previously described, possibly desired variability in terms of inclined surfaces and straight surfaces of the tub carrier ultimately composed Lich, the Ausneh lines 5 in the tub support base 4 can also be arranged symmetrically distributed such that the tub support supplement 2 in both possible orientations with the Tub support base 4 can be connected.

It can also be seen that the tub support base 4 has an opening 6 associated with its two narrow-side end regions. This can be combined with the opening 7 described below in the tub support add-on piece 2 to supplement a conventional assembly opening.

From the cross-sectional view according to FIG. 3, it is clear that the tub support supplement 2 is positively connected to the tub shape 1 , namely here in the region of edge overlaps the tub support form 1 .

From the cross-sectional view of FIG. 4 it can be seen that the tub support base 4 forms an underside attachment surface 8 , here in the form of a peripheral area and a center piece 9 . In addition, a connecting channel 10 is formed in the tub support base 4 between the two openings 6 , in which any drain lines etc. can be arranged.

From the illustration of FIG. 5 it can be seen that the tub support supplement 2 in the area of a tub drain 11 is immediately provided with an opening 7 ; an underside 12 of the tub shape 1 is exposed in this opening 7 . The opening 7 complements one of the two openings 6 of the tub support base 4 to form an assembly opening. The procedure for installing a bathtub in the form of the tub shape 1 of the object in FIG. 1 is as follows:

First, the tub support base 4 is covered on the underside, on the bottom surfaces 8 , with an adhesive, for example local foam. Then the tub support base 4 is aligned at the intended location on the floor and by curing the foam, it aims to arrest. In the next step, the tub support add-on piece 2 with the tub shape 1 inserted therein is connected to the tub support base 4 . As in the exemplary embodiment shown, this can be done in a form-fitting manner. However, it is also possible, for example, to carry out simple, planar bonding. Then after an assembly opening in the side wall of the tub support so assembled, in the area of the drain opening 11 can be cut out and a drain set can be installed or, in the case of a preassembled drain set, a last interconnection can be carried out or a tightness can be checked.

The further embodiments described below games are based on the described basic version. The Where necessary, reference numbers are used accordingly applied, sometimes without repeated text.

A spigot version is also explained, which makes tube-fitted trough shapes 1 factory-assembled by a certain configuration of the spigots 3 , which engage in corresponding recesses 5 between parts 2 and 4 .

First of all about the further training measures: These consist primarily in an installation-friendly design of the support part near the floor, that is to say the base support base 4 . The has side openings 13 . Allowing the optional tubing of the openings 6 and, if necessary, the opening 6/7. A corresponding pipeline 14 is shown in FIG. 7. Above all, it concerns waste disposal lines.

The openings 13 are preferably near the corner of the tub support base 4 , not only in the longitudinal sides, but, as can be seen from FIG. 7, also in at least one of the narrow sides.

The side openings 13, which are implemented in the majority, are realized as grooves extending from an upper side 15 of the tub support base 4 . The corresponding de bottom of the tub support supplement 2 usually closes the upward entrance of the grooves. So there is a window cavity closed, so to speak, from a lintel.

From the second embodiment, in particular Fig. 7, it is clear that there are two openings 13 lying on a common transverse plane in the opening 6 there opening. In contrast to this end of the trough shape 1 on the foot side, the openings 13 lying on the same transverse plane of the head end of the same each form part of the regions 6 forming the opening there. In other words: according to the design of the tub support base 4, the assembly chamber there is divided as a lattice component, namely longitudinally. A longitudinal web of the same which forms the corresponding lattice component is designated by 17 . The cross several crossbars 18th The roots of the inside of the tub support base 4 designed as a frame. The longitudinal web 17 lying in the divided assembly chamber is also rooted accordingly.

Rabmen's legs are spaced apart, the transverse webs 18 are provided with notches 19 which are similar to the openings 13 and extend from the upper side 15 of the tub support base 4 . They are congruent in the longitudinal direction, so that they form a trench structure comparable to the connecting channel 10 . It is pipe-bar. The notches 19 also extend congruently to the narrow-side openings 13 at the head end of the tub support supplement 2 .

The notches 19 are held by a suitable lattice structure on the underside of the tub support add-on piece 2 . This is also the support effect of the superstructure against the tub support base 4th Reference is made to FIG. 9. It can also be seen there that the lattice structure 20 or the supplementary piece 2 provided therewith also forms the foot-side assembly chamber at least with an opening 7 . The same can also be seen in relation to the divided opening 6 (cf. FIG. 7).

In addition to the fit-fit Steckver described in detail between the parts tub support supplement piece 2 and tub support base 4 via the pin 3 and the recesses 5 , another vertically oriented docking method is used. This is such that on the underside of the tub support base 4 , that is to say on the underside 16 of the tub support walls, joining strips 21 are formed. They only extend in the longitudinal direction, but can also be designed on the transverse side. The joining strips 21 engage in suitable recesses 22 . They are located on the top 15 of the tub support base 4 . These joining means can of course also be placed the other way round. The recesses 2 are here sen sen. Otherwise, they cut the openings 13 .

Another peculiarity of the tub shape according to the second and third exemplary embodiments is then that the tub support base 4 has a holder 23 . It carries an overflow pipe 24 . This continues in the usual connections facing the assembly chamber and tub there. The bracket 23 is made of the same material as the tub support base 4th The holder 23 is adjustable in height in a vertical recess 25 from FIG . 4 . Which is open to the opening 6 there. Your flanks are serrated lengthways. They engage in corresponding recesses on the narrow sides of the holder 23 . A cross-section-corresponding recess continuation 26 is located on the wall of the tub support supplement 2 facing the opening 7 . It is equipped with the same management tools as described. The corresponding positive locking profiling is designated in its entirety by 27 .

The overflow pipe 24 merges into a connecting plate 28 at the top. The latter can be raised to a height at which the tub drain opening 11 of the tub shape 1 is located.

Referring to FIG. 7, the bracket 23 of the tub support base 4 rises above an upper connection plane. This level is defined by the docking joint between top 15 and bottom 16 .

The tub support according to the third embodiment differs in further structural details compared to that according to the second embodiment. The tub support base 4 according to FIG. 13 are nevertheless recesses 22 for corresponding joining strips 21 are formed . These recesses 22 are te at one end, here at the top of the tub support base 4 open. The relevant longitudinal groove opens into a side surface, here the narrow or transverse side of the tub support base 4 . In the opposite direction, ie in the area of the tub support foot end, a sliding stop is formed on the tub support base 4 . For this purpose, for example, one side limitation 29 of the tube recess there is used, provided by the openings 13 .

The openings 13 , which have a greater horizontal depth here, pass into a more rudimentary assembly chamber, that is to say opening 6 . The side border 29 forming the flank of these openings 13 runs over a convex curve 30 into the vertical recess 25 .

The two rail groove-like recesses 22 allow a horizontal sliding installation. The joining strips 21 are threaded into the recesses 22 from the open side. A guided displacement takes place in the direction of the holder 23 .

With regard to the cross section of these recesses 22, undercut-like, for example, dovetail-shaped grooves can be realized. In order not to have to be in the plug-in assembly over the entire sliding length, the flanks of the said coupling means can converge in the direction of assignment. So can the rail reinforcement te tub support supplement 2, for example. Halfway down the length of the overlap vertically and then move accordingly. When the defined end position is reached, in which the outline of the tub support he supplement 2 is congruent with the corresponding outline of the tub support base 4 , the holding tion 23 can then be positioned exactly vertically, that is to say also in part in the recess continuation 26 will be. The bracket 23 acts practically like a bolt. If a complete immersion depth for the holding tion 23 in the tub support base 4 is not provided, an end wall section of the tub support addition piece 2 can be cut free.

In order to favor this fiddling, a portal-like recess 31 of the longitudinal wall of the tub support supplement 2 is associated with a lateral opening 13 . The ( 31 ) is realized as a groove cut from below, that is to say from the underside 16 of this component. Their opening is opposite to the upward opening of the opening 13 there .

With such a configuration, the effect of the side boundary 29 does not come about. In assignment of such recess 31 thereby Endbegrenzungsmittel a longitudinal closure of the recess 22 are preferably or 21 / Use the stop action of the converging flanks of the parts 22 in the form.

The recess 31 can have the usual dimensions of an inspection shaft.

Taking up the idea of giving the tub support an oblique longitudinal wall and a straight longitudinal wall, a useful measure has also been taken in this regard. This consists in the fact that 4 spacer pieces 32 are formed on the tub support base. These ensure, if provided, the determination of a wall distance to the cell in which the tub support is to be installed.

13, two ecknah arranged basically spacers 32 per longitudinal side, respectively, transverse side are shown in FIG. Considered. They are assigned in such a way that they can be easily removed when not in use, simply by canceling. In the foot area of the spacers 32 , predetermined breaking points are taken into account. In terms of construction, these are simple vertical strips which have the same height as the tub support base 4 .

The subject of the fourth embodiment be as a bath shape, the shower tray or shower tray. Equal accessibility to assembly is important here. The tub support base 4 shown in FIG. 15 has a square plan. It has openings 13 formed at least on two sides. These are also close to the corner.

Fig. 20 shows an embodiment in which the breakthrough surface 13 are aligned equally on four sides. As shown, openings 13 of different widths can be involved. Such, in each case rotatable by 90 ° mounting plate is stable in itself and load-bearing in relation to the superstructure, which is also increased by a tub support piece 2 . The plug means 3/5 are formed out in the manner described. In the more theoretical view images Fig. 19 and 20, the recesses 5 are omitted for the pivot 3. However, they clearly result from FIG. 16.

It is provided that the tub support, in particular re lying in training as a shower tray support in the square's plan, has a plurality of recesses 13 for receiving a siphon 33 . With regard to the recesses, there are pot bores 34 .

Recess cup bores 34 of this type are arranged on, for example, four circles 35 of different diameters, specifically in the corner regions of the square. The center of these circles 35 is the intersection of the diagonals of the square. The center of the Wannenträ ger base 4 is designated x. The diameter jump of the circles 35 is the same in each case.

A radius point y of a recessed pot bore 34 lies on each circle 35 at an angle of 90 °.

The illustration in FIG. 19 intuitant is ersicht Lich that the pot bores 34 x from a maximum distance from the center to a minimum Entfer voltage to this stepped off or increase. Stations a, b, c and d are formed in the order mentioned, clockwise to x increasing in distance. Accordingly, viewed in reverse, the individual pot bores 34 are spaced differently from the respective four sides of the square. By each turn by 90 °, the suitable docking area can be selected, also with regard to the openings 13 .

The illustration in Fig. 20 is built up in the same way. It differs only in that there are also two special stations, which offer bezüg Lich the pot holes 34 an enlarged in the radial direction ßstelle. These stations, again seen clockwise, are labeled e and f. So there are two recesses from two overlapping pot bores 34 . The overlap depth is approximately half the radius of the pot holes 34 . The radius points y of the added, as it were peripherally saddling pot holes 34 lie on added circles 35 in the underlying same circular distance diameter jump.

It can also be seen from the said figure that the overlapping cup bores 34 are oriented on a radial with respect to the center x.

In the middle field, the tub support base 4 leaves a support area 36 . The foamed-in floor 37 of the tub shape 1 in question rests on this. The support area 36 can be seen from Fig. 16 as a plateau.

An edge formation 38 is realized at a distance from the support region 36 . The forms with your top 15, the joint-forming pad to the corresponding bottom 16 of the tub support supplement piece. 2 The edge formation appears as a peripheral re wall that leaves gaps between them, which represent the openings 13 described. The recesses 5 are located in the corners of the edge formation 38 .

A depression 39 lies between the support region 36 and the edge formation 38 which is designed at the same height. From this lowering 39 , the recesses closed at the bottom, that is, pot bores 34 .

The bottom of the window-forming openings 13 is level with the depression 39 , the depression 39 is arranged all around. It surrounds the plateau-shaped support area 36 as a ring valley.

The tub drain 11 in the bottom 37 of the shower tray with respect to the foam-covered wall portion of the Wannenträger- supplementing piece 2 in the underfloor area accessible supported th. Ecktunnel this purpose, a 40th It is open to the bottom side 16 of the tub support supplement 2 and also opens near the corner into the adjoining side walls of the relevant tub shape 1 . On the ceiling of this corner tunnel 40 there is a breakthrough in the foaming material and above the tub drain opening 11 .

The width of the mouths of the corner tunnel 40 corresponds to that of the respective opening 13 below. The corner tunnel 40 can also have a rather angular shape instead of an arch shape.

Regarding the tub support base 4 remains to be noted that this drain pipes can be foamed assigned. In this sense, it should also be cheap to make the closure, the docking of the parts Wannenträ ger supplementary piece 2 and tub support base 4 factory.

In such a case, the latching connection shown in FIGS . 10 and 11 can particularly advantageously engage. In the overall tapering pin 3 , a self-defining underhand takes place via a bead-like attachment head 3 '. There is a highly addictive anchoring the vertically oriented plug connectors 3/5. In the first means of the plug connection shown in FIG. 11, the restraining head 3 ′ is formed at the free end of the pin 3 , in the version shown in FIG. 11 over half the length of the pin 3 . In both cases there is almost an irreversible connection. Further de tails result from the unpublished German patent application 197 53 375.2.

The tub support of all exemplary embodiments is underlaid for acoustic optimization. It is a soft foam pad 41 . The is grid-like and takes into account the corresponding web course of the parent parts or the frame shape of the tub support supplement 2 of the shower tray. In the latter case, however, according to FIG. 17 there is also a lattice shape, so that the corresponding acoustic barrier is given in the underfloor area of the support 36 as well as in the edge area.

The thickness of a corresponding plastic foam is between 0.3 and 1.5 cm. The overlying underside of the tub support base 4 can, as can be seen, for example, from FIG. 13, carry a longitudinal groove 42 . This can also be arranged on the longitudinal web 17 shown in FIG. 15. So it comes to a, as seen in cross-section, hat-shaped joint profile between the soft foam pad 41 and the higher-level part made of particle foam. For example, polystyrene particle foam is used here, with a specific weight of 15-50 kg / m ³ , preferably 23-30 kg / m ³ . The softness of the foam pad 41 is such that the weight of the tub together with the tub support base 4 and the filled water and a person using it preferably compresses no more than half the thickness of the pad 41 . About a twentieth to a third of the base of the tub support falls on the load-bearing surface. The relatively hard foam of the base 4 provides a joining roughness towards the base 41 .

The soft foam only needs to be loaded Area size to be provided. It's about a PUR elastomer with a mixed cell structure and demented  excellent dynamic properties. Static and dynamic modulus of elasticity are almost the same. The tendency to creep is also low.

The foam has closed pores and an open-pore structure. A wide area has been knotted. The skin is labeled 43 . The other porridge shows a roughening, realized in the manner of a waffle pattern 44 .

In the following, some functionally relevant, physical properties of this mixed cell material are to be given.

The subject of the fifth to seventh game Ausführungsbei concerns again as tub shape 1, the shower tray or shower tray. The has essentially quadratic plan and is with regard to the accessibility of the siphon 33 and the outgoing pipeline 14 inexpensively revisable. Corresponding features are identified by the numerical symbols of the above-described solutions, sometimes without repetitions. Nevertheless, the advanced training, technically implemented, can also be trained on the bathtub. Instead of individual completed Durchbrü surface 13 is now in a corner region of the tub support 45 allows for a relatively large access opening 46th The detects both side walls of the tub support running together at an angle of approximately 90 °. The revision opening 46 is accessible by removing a Siphonkam mer 47 peripheral opening part 48 .

By removing the corner portion 45 through the opening part 48 , the inspection opening 46 is simultaneously cleared in both side walls. This allows an optional access from one side wall or the other side wall, depending on which of the side walls is blocked by the wall of construction. Otherwise there is even the advantage of full opening.

The opening part 48 , which flushly adjoins the inspection opening 46 on the outside wall, is consequently designed as a corner piece in accordance with the corner contour. It has a basically rectangular plan, the apex zone of the angle forming a vertically oriented, concave bay 49 . This creates space in terms of the shape or the space requirement of the Si phone 33 and the power connection.

The inspection opening 46 is also spatially adapted as the filling core of the opening part 48 . In this respect, the opening part 48 is used as a load-bearing "stone" in a two-part joint assembly here. The thickness of the side walls also continues almost uniformly in this area. This can go so far that the opening part 48 forms part of the support for the tub floor surface 37 ', even the direct, at least partially.

According to the first embodiment, the Revisionsöff opening 46 is opening in the region of the side walls of the tub support supplement 2 . It therefore extends above a joint 50 formed between the upper side 15 of the tub base support 4 and the underside 16 of the tub support add-on piece 2 . Below said joint 50 , said siphon chamber 47 attaches to the base of the tub support. The siphon chamber 17 closes with respect to the tub support base 4 to the corner region 45 there with siphon chamber wall sections 51 . They go up to the top 15 .

A recessed pot bore 34 also extends vertically in alignment with the outlet 11 . This increases the depth of use of the siphon 33 beyond the bottom of the siphon chamber 47 .

The ceiling of the inspection opening 46 extends to the Eckbe area 45 ascending sloping roof. In an adaptation, the assignable opening part 48 tapers in the direction of the tub drain 11 . The corresponding taper is particularly clear from Fig. 52. It is a wedge-like taper. The corresponding wedge surface bears the reference symbol 52 . The counter support side of the trough support bears the reference character 53 . The wedge surface 52 only covers a partial surface of the outline of the opening part 48 near the corner. The wedge angle can be in the self-locking area, although the roughness of the material would counteract a deflection component. Such a deflection component hardly exists due to the remaining, more flat-shaped design of the opening part 48 .

Instead of just an upper side, a wedge-shaped taper on the underside can also be provided; even tapering on both sides is conceivable. In all cases, the greatest vertical thickness of the wedge is reached in the corner line 54 , from which the wedge surface, based on an bisector, is completely symmetrical.

To make the opening part 48 easier to handle, recessed grips 55 are arranged on its outer walls which are at an angle to one another. They are a good two fingerkup in size and, moreover, spatially spaced around corners so that they also correspond to the grip of an adult human hand. You can use a handle that goes over a corner as well as a purely sidewall-related one.

As can be seen, for example, FIG. 26, the two angled legs of the opening part 48, which is angularly shaped in plan, continue in each case in a horizontal side wing 56 . Suitable entry grooves 57 of the tub support are assigned to them. They ( 56 ) have a reduced vertical thickness and are also somewhat narrower than the width of the legs of the opening part 48 . Such a tongue / groove engagement allows the opening part 48 to be held in the inspection opening 46 even if it is not yet closed, for example by the comb of the siphon chamber wall sections 51 . The tub support according to the seventh exemplary embodiment does not provide the plug connection explained. A frictional connection is also conceivable.

Referring to Figs. 33 and 35 will be explained below further developments. The relate to measures that favor the easy, safe acquisition of a Gefäl les of the pipeline 14 . The circumferential, trench-like depression 39 , in which the pipeline 14 is laid, namely shows in the remaining Eckbe range of the tub support base 4 each a support web 58th They run in the bisector of the 90 ° connections of the trench-forming depression 39 . They extend, frame-related, miter-like. The support webs 58 are integrally formed. They can extend to the level of the central support area 36 of the tub support base 4 , that is to say to the top 15 .

A predetermined upper-side saddle depression 59 forms the support for, for example, elbow 60 of the pipeline 14 . Such manifolds 60 are shown in FIG. 57.

The profile of the saddle troughs 59 can be easily further peeled if the pipeline 14 is lowered. This can be done with a common tool, such as a pocket knife.

The pipeline 14 can optionally be laid using the circumferential lowering 39 . Starting from the tub drain 11 or siphon 33 , a diagonally running, trench-like depression 39 can also be used, which is indicated, for example, in FIG. 33 in dash-dotted lines. Even a cross diagonal is conceivable.

The corner formations providing the support webs 58 are uniform in all three corners, but two support webs 58 , lying in the region of the depression 39 , are connected by an even deeper channel recess 61 . The underlying reason can form a starting point for further lifting of the lowering 39 or can also be used, for example, for laying lines such as, for example, grounding cables. The left-hand corner formation shows a short extension which leads into the subsequent depression 39 , also designated 61 .

As can also be seen in FIG. 33, the siphon chamber 47 has 39 spacers 63 in front of the entrances of the trench sections of the depression leading away at right angles. They can be removed in a way that is appropriate for relining, ie cut vertically from a maximum height. The initial gradient of the pipeline 14 can thus easily be correctly determined.

Also in the added embodiments, the dimensional matching of the addable parts is such that the tub support base 4 and the tub support add-on piece 2 in the vertical direction complement each other to the height of a conventional tub or shower tray support. Nevertheless, a correspondingly compact Bauwei se for the laying of the pipes 14 is sensibly divided, which is further reflected in the construction that the depression 39 in the tub support base 4 is supplemented on the top by a recess 64 in component 2 . The recess 64 extends congruently to the lowering 39 in the tub support supplement 2 and thus creates a tunnel-like superstructure. This can go up to half the total height of the trench.

Trough shape 1 and tub support supplement 2 are assigned to each other so that an molding Fugenver run between the two. In other words, the tub support supplement 2 also forms all the curves of an inserted tub floor 37 in a boundary surface. This already leads to stable support. In order to reinforce this, it can be of advantage, particularly in the case of so-called acrylic tubs, if the tub support supplement 2 has a higher density in an area forming the support surface for the tub floor 37 . The corresponding interface layer is designated 65 . It results, for example, from FIG. 37. This creates the possibility of working with the form 1 tubs even thinner. Nevertheless, there is a high load capacity, the interface layer 65 has a density of approx. 60 g / l.

Below the region of higher density, that is to say the interface layer 65 , there is a region of lower density which occupies the predominant thickness. This is 60 g / l.

The interface layer 65 can also continue in vertical extensions. This is also shown in Fig. 37. As can then be seen in FIG. 39, such strip-like, vertical extensions 66 extend to the top 15 of the tub support base 4 . In this case, even the areas of lower density lying between such strip-shaped extensions can be excluded from one another, in the interest of sound decoupling. The guide structure corresponds to the rib structure of the base 4 .

The same also applies to the measure discussed in connection with the fourth embodiment, namely the assignment of a soft foam pad 41 . This would correspond to the lattice structure as shown in FIG. 34.

Another, likewise practicable measure for the acoustic optimization of the tub support would be the interposition of such a soft-foam intermediate layer 41 , as shown in FIG. 36. This takes into account the contact areas in the area of the joint 50 between the tub support supplement 2 and the tub support base 4 .

Now for the sixth embodiment of the tub support:
This is shown from Fig. 40 and corresponds in its basic technical concept to the solution described in detail in Fig. 25 ff. Here, too, the reference numbers are used analogously without repetition of text. The difference is embodied in that the opening part 48 , now the parting line 50 between the tub support base 4 and tub support supplement 2 in both directions of the vertical overlapping, both in the tub support ger supplement 2 and in the tub support base 4 . This is clearly shown in Fig. 42. There are simply the siphon chamber Wandab sections 51 omitted. The recess in the Wannenträ ger base 4 thus goes to the bottom of the siphon chamber 47th The otherwise identical opening part 48 is supplemented in depth by this amount of recess, that is, thickened in the vertical.

Optionally, the remaining features such as the formation of a support web 58 , the creation of a harder boundary surface layer 65, etc. can also be used in this sixth embodiment, for example.

The two basic elements, tub support base 4 and tub support supplement 2 , connect the plug-in means, realized as pins 3 and recesses 5 . are delt from the fifth embodiment. The pins are now also designated 3 strip-like projections on the underside 16 of the tub support member 2 and congruent lying, designated 5 longitudinal grooves in the top 15 of the tub support base 4th The insertion depth is such that excess, displaced adhesive, for example silicone adhesive, can collect, evasive to the bottom of the grooves 5 .

The seventh embodiment ( Fig. 43 ff.) Shows a modified type of plug assignment of parts 2 and 4 . Here the tubs showing the total height of the tub support 17305 00070 552 001000280000000200012000285911719400040 0002019847911 00004 17186 support add-on piece 2 is placed over the edge of the tub support base 4 . The tub support supplement 2 is hen with a corresponding overlapping apron 67 verses. The protrudes beyond the underside 16 of the tub support supplement 2 sufficiently far down. The end face of the apron 67 goes to the floor, ie to the footprint of the tub support.

In order to ensure access to the siphon 33 and the outgoing pipeline 14 here, too, the corner area 45 is left open, forming a portal 69 that goes over a corner. The corresponding interruption of the apron 67 in the area of the inspection opening 46 is such that the apron 67 and the corner area 45 of the tub support base 4 projecting outward through the portal 69 are flush on the outside. The vertical outer walls of the opening part 48 , which are at right angles to one another, run on the same plane as the said surfaces. The edge region receiving the wall sections of the apron 67 has one of the wall thicknesses corresponding to the inward projection 70 .

The variant according to FIGS. 53 and 54, which also has an apron 67 , clearly shows the corresponding projection 70 , as does the portal 69 on the underside 16 of the tub support supplement 2 . Fig. 54 shows a different umrißmäßig Siphonkammer 57th The tub drain 11 , which is moved further inward here, extends in an elevated section that encircles the depression 39 . The corresponding plateau is designated 71 . The plateau-forming, trench-shaped section runs as a straight line that is perpendicular to the diagonal. The straight line corresponds to the section line LVI-LVI shown in FIG. 55.

The plateau 71 is in turn in the end region of the elevated section from removable pillars 63 protrudes. The pot bore 34 then lies between the two spacer brackets 63 in a region which is likewise elevated compared to the plateau 71 . It is framed and can also be removed to adapt to the most diverse siphon types. This central area then merges into a diagonal branch channel 72 directed inward from the trough.

The subsequent ends of the circumferential depression 39 are again approximately recessed relative to the plateau 71 .

Now to the detail according to FIG. 57: The sections of the reduction 39 go into one another at an angle of 90 °. As already stated, the support web 58 is located in the angle halves. The saddle recess 59 carries the coupling point 73 of two tightly connected elbows 60 here . They enclose an angle of approx. 140 °. Due to the linear plug-in sections of the elbow 60 there is a generous deflection of the pipe line 14 ; this flow-critical zone is not clogged as easily as with a strictly 90 ° covering elbow. The perpendicular to the diagonal or bisector, curvature-reducing deflection is referred to 74 with respect to the straight line.

Fig. 58 shows with respect to the reduction 39 is a more particularity. The pipe 14 proceeding from the local siphon 33, which is shown largely schematically, is connected via a ball coupling 75 . He stretches in a contoured Zwischenkam mer 76 between the pot bore 34 of the tub support base 4 and the leading section of the graben-shaped lowering 39th This connection zone can also be checked by the inspection opening 46 that can be exposed via the opening part 48 . The circular arrow drawn around the center of the siphon axis illustrates the feasibility of the connection direction.

In Fig. 34, spacers 32 are shown on the tub support base 4. Their meaning is explained in relation to FIG. 13.

In FIGS. 59-73 further developments are set out an the target-oriented docking disposal-related lines facilitating solution, further the assembly otherwise further favoring measures. Since the basic principle of tub support division is also retained here, the reference numbers are appropriately transferred, sometimes without repeated text. The further education measure takes advantage of the division of the tub support into a kind of plug function. For the mechanical docking are arranged here in corners of the upper side 15 and bottom 16 arranged pin 3 ge. They can consist of parts that are harder than the rigid foam used, similar to the above-mentioned vertical extensions 66 in FIG. 37. However, the pins 3 are preferably composed of separate parts. They are inserted and fastened in vertical pockets 78 which open towards the underside 16 . The pin 3 consist of hard material, for. B. a hard PVC.

Wooden rods, strips, etc. are also conceivable. The recesses which accommodate the pins 3 thereon and are congruent have the reference number 5 . They start from the top 15 of the tub support base 4 .

Aligned in parallel to the vertical spigot 3 extends, also the joint 15 , 16 exceeding a connector part 79 of an Ab- and Überlaufeinrich device E. The fittings are distributed on the two basic components of the tub support. Accordingly, the drain and overflow device E is partially in the tub support supplement 2 and partially in the tub support ger base 4 . According to the illustration, it looks like that one of the joining area F between the tub support base 4 and the tub support add-on piece 2 assigned interface between sub-devices E 'and E "in the course of the joining of tub support-He add-on piece 2 and tub support base 4 automatically The plug part 79 enters a socket part 80. Both extend in a common vertical central axis and are cross-sectionally matched.

The partial device E 'containing the socket part 80 is seated in the pan support base 4 . The other Teileinrich device E "is accessible with respect to the joining area F in the tub support supplement 2 .

With regard to the socket part 80 , there is an annular seal in the form of a sleeve 81 . It can consist of rubber or rubber-like plastic. A centering funnel 82 extends from its ceiling, which favors the plug-in finding. It can be a lubricant up, which still favors the connector.

The cuff 81 is clipped with a siphon pot 83 randver. The siphon, also designated 33 here, continues in an upward-projecting bend 84 , forming an odor trap, adjacent to the siphon pot 83 . The siphon 33 is net pivoted about a vertical axis. A connecting pipe 85 also rotatably connects to the elbow 84 . This can be equipped with a disposal pipe, which can be shifted optionally via the connecting channel 10 . The present Wannenträ ger base 4 namely has two parallel, near the edge connecting channels 10 .

All power connections are common sealed.

The plug part 79 leads to the bottom 37 of the tub shape 1 with a connection there to the tub drain 11 . The associated overflow near the tub has the reference character 86 . A first line 87 leading to the tub outlet 11 extends from the latter. This follows winkelabge fits the area of the tub shape 1 there . Accordingly, it continues in a substantially horizontal ver running, downward in the direction of downflow from section 88 continues. This sub-device E ″ then includes the second line 98 , which leads away from the tub drain 11 and points in the direction of the first sub-device E ′, forming the plug part 79 .

The second line 98 forms a clearly projecting connection section 90 , this with a bevelled edge on the outside, so that the desired centering effect is further supported.

A look at Fig. 59 shows that the connecting section 90 or the second line 89 providing it has a smaller vertical free-standing length than the pins 3 , so that they act as spacers; in other words, the connection section 90 does not touch the footprint, for example a raw floor of the building. On the other hand, the pins 3 are sufficiently leg-forming sta bil, since they are made of relatively harder material than the tub support.

The variant shown in FIGS . 62 to 64 shows an embodiment in such a way that the first line 87 and the second line 89 have connection sections 90 directed separately from one another at the sub-device E 'in the tub support base 4 . These in the case of the underside 16 of the tub support supplementary piece 2, the connector-forming lines 87 , 89 are connected to one another in a stabilizing manner via a cross strut 91 . It is hidden in the cross-section of the tub support supplement 2 .

Disposal side things look here, so that the partial device E ', housed in the tub support base 4, corresponding to two terminal pots 92 provides, one of which lying in Fig. 63 right of the local siphon is provided 33, beschrie surrounded Siphontopf 83rd Otherwise the structure is the same. It should also be mentioned that the left-hand connection pot 92 is connected to the siphon pot 83 via a cross line 93 .

The Teilein device E 'located in the tub support base 4 is held in a separate receiving part 94 from the tub support base 4 . This consists of the same material as the tub support base 4 .

The receiving part 94 can be displaced in a horizontal plane and is assigned to the opening 6 of the tub support base 4 which is made smaller there. The opening 6 , in the longitudinal direction of the tub support base 4 , is longer than the length of the receiving part 94 measured in this direction, so that a relatively large adjustment path is available in the relevant axis. The ends of the opening 6 form limit stops of the receptacle 94 which is displaceable in the said plane. The latter is in the underfloor area of the tub shape.

The receiving part 94 holds the siphon 33 and can be set up precisely in this regard to the position of the plug part 79 and securely fixed in relation to the tub support base 4 .

To achieve guided displaceability, the longitudinal edges of the opening 6 are profiled. This looks in detail such that a stepped opening 6 is formed in the tub support base 4 . It is an intervention step. The gradation on the carrier side is on the installation surface side. The lying in a depression 95 opening 6 is then in relation to a base step 96 of the sled-like receiving part 94 dimensioned so that there is also mobility in the transverse direction with respect to the tub support base 4 . The base step 96 can be flush with the flat surface of the depression 95 . The bottom of the connecting troughs 10 extends at the same height as the depression 95 .

The underside, undercut-like steps are labeled 97 . In the projecting side wing 98 of the receiving part 94 . The side wings 98 are used to fix the receiving part 94 . They can be used to apply an adhesive layer 99 , via which the adjusted position of the receiving part 94 is secured. The adhesive layer 99 occurs against the corresponding bottom surface of the steps 97 .

Fig. 68 shows possible Verkippungslagen of the receiving member 94. This extends at the same level to the underside of the tub support base 4, which may be ribbed.

To fix the siphon 33 , the receiving part 94 forms a trough 100 on the upper side. This takes into account the outline and depth of a partial area of the sub-device E 'bound by it, that is to say of the siphon 33 . Its silhouette is comparable to a key cross-section (shaft and beard). Accordingly, the trough 100 turns out like a keyhole, the larger round region 101 of the trough 100 receiving part of the interface forming siphon pot 83 . The Rundbe rich 101 tapers to the closed bottom of the receiving part 94 , this in the form of the adaptation to the outer contour of the siphon 33 embedded practically halfway up.

In terms of construction and procedure, the procedure is such that the separate parts are fitted with fittings. They receive their drain and overflow device, that is, the tub support base 4 receives the partial device E ', the tub support supplement 2 , the partial device E "is incorporated. This can be due to the greatest possible foaming or within the scope of a shaft-using assignment The partial device E 'accommodated in the tub support base 4 is fixed in position during a first assembly of the tub support base 4 and the tub support supplement 2. To determine the corresponding coaxiality of the plug part 79 and socket part 80 , the receiving part 94 is set and fixed 33. The corresponding congruent alignment of the parts of the tub support supplement 2 to the tub support base 4 can be achieved via the dowel-like function of the pins 3 , which, as stated above, prematurely enter their suitable recesses 5. After complete closure, they are closed the two parts to be joined are individualized. In a second assembly, parts 2 and 4 are finally connected. This makes installation on site easier and considerably less time-consuming. Parts 2 and 4 can be brought together in adhesive bond. Previously, the bathtub base 4 is fixed to the raw floor of the building structure via construction foam for the correct placement of the tub support. The corresponding tree foam layer also covers the underside of the receiving part 94 , since part 4 is flush. The receiving part 94 thus functions in the plug-in assignment as a non-designing stable abutment against the coupling or joining forces. A bead thickness of approx. 1 cm is sufficient for the PU foam.

An inspection opening can be cut.
