(2) FIG. 1: A perspective view of the invented carrier body, showing a sealing membrane covering its bearing surface.

(3) FIG. 2: A sectional view along Sec. I-I of FIG. 1, in an expanded scale.

(4) FIGS. 3a to 3c: The right side area of Sec. I-I of FIG. 2, which is cut through the carrier body and presents exemplary possibilities for mounting an invented carrier body adjacently to neighboring surfaces.

(5) FIG. 4: A section through an invented carrier body, similar to that of FIG. 1 along the line I-I, drawn in a greater scale, wherein the sealing membrane has been affixed to the inner bottom side of the carrier body.

(6) FIGS. 5a to 5g: The right side area of the section shown in FIG. 4, presenting exemplary possibilities for the mounting of the invented carrier body onto neighboring surfaces.

(7) In the following is to be found an explanation and a more detailed description of the invention, with the aid of the above Figures, in accord with surrounding construction and, where necessary, also providing the method of operation of the said invention.

FIG. 1

(8) In the perspective presentation of FIG. 1, the invented carrier body 1 is depicted from an inclined view from above. In this view, the carrier body 1 possesses an upward exposed bearing surface 2, which is to be provided with a sanitary surfacing material 3. This surfacing material may be an acrylic coating or a tile covering or the like. In the perspective view of FIG. 1 the basic bearing surface 2 is designated as having within its borders an inner, centrally located first partial area 6. Correspondingly, the surface 2 also possesses a peripherally surrounding outer second partial area 7. The said first (inner) partial area 6 of the bearing surface 2 is that portion of the said bearing surface 2 of the carrier body 1 upon which a sealing membrane 8 is adhesively affixed. This sealing membrane 8 is represented in FIG. 1 by dashed lines and extends outward away from the first (inner) partial area 6. The same sealing membrane 8, however, covers the second (outer) second partial area 7 of the bearing surface 2 in a temporarily loose, non-affixed manner. As the perspective presentation of FIG. 1 indicates, that the sealing membrane 8 thus overlaps the edges 9 at the periphery of the carrier body 1.

(9) In this perspective presentation of FIG. 1, the bearing surface 2 is shown inclining itself downward from all directions toward a center point. At this center point of the carrier body 1 is provided an opening 10, which serves for connection to existing draining facilities in, presumably, a substrate and/or a supporting flooring.

(10) In accord with the invention, it remains possible for the carrier body 1, as may be seen in the section of the second (outer) partial area 7, to be adjusted into alignment with the field dimensioning of the shower location. This adjustment could be carried out in some instances by means of a cut-to-fit operation. This advantageous adaption of size can be carried out on site by workmen with tools readily at hand, including, for example, a saw. Thus, in accord with this operation, a rapid and simple fitting of the outside dimensions of the carrier body 1 to the space requirements of the shower site is made possible at any time.

FIG. 2

(11) In FIG. 2, the FIG. 1 section along the line I-I of the carrier body 1 is shown in an enlarged scale. In FIG. 2, the first partial (inner) area 6 is made evident with a firmly attached part 11 of the sealing

(12) membrane 8. Likewise is exhibited the second partial (outer) area 7 with an overhanging, loose part 12 of the sealing membrane 8. As has already been mentioned, in the case of the through-cutting of the carrier body 1, first, the mentioned loose part 12 of the sealing membrane is folded back out of the way. Thereafter, the carrier body 1 is separated, i.e. cut, through the second (outer) area 7. When the cutting is finished, then the loose part 12 of the sealing membrane is again brought down onto the now trimmed section of the second (outer) partial area 7 and firmly attached thereto by adhesive means. When this is done, either before or after the cutting and adherent affixing, the loose part 12 of the sealing membrane 8 can be evenly trimmed. The result of this trimming allows the now cut-to-fit edge 13 (see FIG. 3a) of the second (outer) part of the carrier body 1 to be evenly overlapped by the sealing membrane 8.

FIG. 3a

(13) As the next step, the mounting of the carrier body 1 can now be executed and the said body fitted in alignment with the neighboring surfaces. In methods of operational possibilities, as set forth in FIGS. 3a to 3c, the carrier body 1 is shown as resting on a substrate 14 and its newly cut edge 13 abuts a wall 15. The sealing membrane residual portion 16, which remains after the cutting of the carrier body 1, is shown in FIG. 3a drawn upward (relative to this drawing) along the wall 15. This provides a seal between the wall 15 and the carrier body 1. Tiles 17 may now be laid against the wall 15 and the sealing membrane 16.

FIG. 3b

(14) In the case of the example shown in FIG. 3b, the carrier body 1 is laid over a substrate 14 with a neighboring flooring 18 situated thereunder. In this case, the sealing membrane extension 16 is brought over the joint between the carrier body 1 and the flooring 18. Further, on the upper side of the flooring 18, an adhesive has been applied to unite the two. Likewise tiles 17 are laid against the flooring 18 with the sealing membrane edge 16 protruding from under the tile 5 of the carrier body 1 and intervening therebetween, thus overlapping the joint.

FIG. 3c

(15) As a final possibility in this installation example, it remains to be shown in FIG. 3c, the manner in which the structure of the substrate 14, the carrier body 1, the thereon applied sealing membrane 8 and the tiles 5 are laid upon the said flooring 18. The continuing extension of the tiling 5 proceeds over the end surface of the carrier body 1, follows along the end edge of the substrate 14 and continues over the

(16) flooring 18. From this FIG. 3c can be inferred, that the sealing membrane section 16 is allowed to extend itself beyond the corner between the substrate 14 and the flooring 18. This extension of the sealing membrane section 16 provides an assuredly sufficient sealing.

FIG. 4

(17) The arrangement of an alternate example of the carrier body 1 is presented in the section

(18) shown in FIG. 4. This invented version of the carrier body 1 represents principally the same construction as that of carrier body 1 of FIG. 1. Accordingly, FIG. 4 displays a similar cross section through the carrier body 1 as has been done in FIG. 2. However, in this case, the carrier body 1 of the FIG. 4 differentiates itself from the previous version, in that on its top exposed bearing side 2, it has been protected with a preinstalled acrylic covering material 19. This acrylic covering 19 extends itself, in the FIG. 4, along the carrier body 1 at least to partially over the peripheral edge thereof. It may be inferred from FIG. 4, that the sealing membrane 8, in this case, has been applied against the undermost, i.e. the bottom, surface 20 of the carrier body 1. In correspondence to the invented constructive example shown in the FIGS. 1 and 2, this said bottom surface is likewise in a first (inner) partial area 6, where the sealing element 8 has been adhesively firmly affixed. Likewise, a second and loose segment of the sealing element 8 extends itself freely in proximity to the second (outer) partial area 7 of the carrier body 11.

(19) The cutting to desired dimensioning of the carrier body 1, where FIG. 4 is concerned, is done in the same manner as described previously in regard to FIG. 2. Again in this case, it is of the essence, that upon the cutting through of the carrier body 1 in the second (outer) partial area 7, the loose part 7 of the sealing membrane 8 remain in an uncut state. By means of the inventive carrier body 1, it becomes possible, that the shower location can be specifically defined, with consideration being given to specific dimensioning and that the erection and sealing of the same can be carried out without difficulty.

FIGS. 5a TO 5g

(20) In the FIGS. 5a to 5g are to be found, once again, clearly exemplary possibilities for the placement of the carrier body 1 against the neighboring and adjacent objects and surfaces, such as walls 15,

(21) flooring 18 and the like. Principally in 5b, the determination has been made, that a cut-to-fit carrier body 1 is involved, which is supported on a substrate 14 and is then sealed off against a wall 15 with the aid of the sealing membrane extension 16. Even in this case, corresponding to the construction example of FIG. 3a, the contact area between the sealing membrane residual part 16 and the wall 15 is provided with a tile 17 installation.

(22) The arrangements shown in FIG. 5a, as well as in FIGS. 5c to 5g, demonstrate, for instance, a carrier body 1, which is not cut, so that the acryl covering 19 thereof, remains untouched. In FIG. 5a is shown an arrangement of the carrier body 1, wherein, in accord with the cut carrier body 1 described in FIG. 5b. In this FIG. 5b is shown the carrier body 1 supported on its substrate 14 and this arrangement is then supported on a flooring 18. Such an arrangement is also shown in FIG. 3c. In FIG. 5d the carrier body 1 is found, for example, with the sealing membrane 8 extended thereunder and accordingly lying between the carrier body 1 and the flooring 18. Also in FIG. 5d is to be seen, how the said sealing membrane extension 16 is brought further over the flooring 18, away from the shower site. Made evident also, is that the flooring 18 is sealed off against the carrier body 1, so that the tiling 17 can be laid in an orderly manner onto the sealing membrane section 16 and the flooring 18. In the example depicted in FIG. 5e, the substrate 14 with the thereupon laid carrier body 1 is provided to be somewhat higher in elevation than the adjacent flooring 18. Consequently the tiling 17 can be slipped in therebelow. Again in this case, a sealing is effected at the given points of impact by means of the sealing membrane section 16. Counter to this, in FIG. 5f, a situation is demonstrated, wherein the substrate 14 is lower than the level of the flooring 18.

(23) In the case of FIG. 5f, upon the laying of the tile on the flooring 18, a small difference in elevation marks the joint between the acrylic covering of the carrier body 1 and the subsequent area of tile 17. FIG. 5g makes further adjustment, wherein the combination of the carrier body 1 and the substrate 14 is so aligned with the flooring 18 and its tile 17 covering, that a smooth extension to the bottom is achieved. In both FIGS. 5f and 5g, as can be seen, in actual installation, the sealing membrane extension 16 is folded away, thus projecting over the flooring 18.

(24) The bearing surface 2 and/or the under surface 20 may possess predetermined linear indentations in order that a penetrative, vertical cutting can be carried out along the said indentations. FIG. 2 illustrates such indentations 22 formed on the under surface 20 (each indention being shown representationally as an x in the drawing).
