Description

Technical Field

[0001] The present invention relates to a sanitary device, comprising

[0002] - sanitary ware to be suspended and fixed on a vertical wall and

[0003] - A first fixing device for fixing the sanitary ware on two retaining bolts arranged on the wall, wherein the first fixing device can be fixed to the sanitary ware in a detachable manner or in a detachable manner and has two retaining bolt receptacles, into which the retaining bolts are snapped in the installed position, wherein each retaining bolt receptacle corresponds to a threaded hole, into which a retaining screw to be tightened relative to the corresponding retaining bolt can be screwed. Background Art

[0004] Sanitary ware such as flush toilets, urinals or bidets can be fixed upright or suspended on the wall. During the installation process, a fixing device for hanging fixing is detachably fixed to the sanitary ware. This fixing device has two retaining bolt accommodating parts, wherein each retaining bolt accommodating part is engaged with a retaining bolt fixed to the wall side. The retaining bolt can be a hanging bolt arranged on the wall side, or can be a retaining sleeve screwed onto such a hanging bolt. The corresponding retaining screw used for fixing is screwed into the threaded hole corresponding to the corresponding retaining bolt accommodating part and tightened relative to the retaining bolt, so that the fixing device is firmly connected to the wall side hanging bolt and the sanitary ware connected to the fixing device is firmly connected to the wall side hanging bolt through the fixing device.

[0005] An example of such a fixture or a corresponding sanitary device is described in DE 10 2009 055 977 A1. The fixture is designed in the form of an arm and has two retaining bolt receptacles which are embodied as perforations. In the installation position, the two lateral ends of the fixture snap into corresponding receptacles constructed on the sanitary ware, thereby fixing the fixture on the sanitary ware. In the installation position, i.e. when the sanitary ware is sleeved onto the wall-side retaining bolts and the retaining bolt receptacles clamp these retaining bolts, the threaded holes face downward, i.e., they can be clamped onto the retaining bolts from below with the help of a tool and tightened. On the one hand, this requires that the sanitary ware is correspondingly open in the lower region, so that the installer can reach into the sanitary ware from below with the help of a tool. On the other hand, this installation method is relatively cumbersome and costly. Summary of the invention

[0006] Therefore, the object of the present invention is to provide a sanitary device which is improved compared with the above.

[0007] With regard to the sanitary equipment mentioned at the outset, the solution for achieving the above-mentioned object of the invention is that - in the fixed state of the first fixing device, the threaded hole faces the upper wall of the sanitary ware that carries the seat ring or the top cover kit in the installed position, wherein two wall openings are provided in the wall, and

[0008] - Two second fixing devices are provided for fixing the seat ring or top cover kit to the wall, which respectively include a sleeve that passes through the wall opening in the installed position and is fixed on the wall side by a fixing member, the sleeve having a through hole passing through it and a retaining pin that can be releasably connected to the sleeve and accommodates the seat ring or top cover kit.

[0009] The sanitary device according to the invention enables a very simple hanging installation of sanitary ware, which is usually made of sanitary ceramics, and provides a completely new installation concept. On the one hand, the first fixing device is designed and conceived so that in the fixed state of the fixing device, that is, when it is fixed to the sanitary ware, the two threaded holes face upwards towards the upper wall that carries the seat ring or the top cover set in the installation position (when the sanitary ware is fixed to the wall side). Two wall openings are provided in the wall, which enable access to the interior of the sanitary ware from above. The two wall openings are used to accommodate the second fixing device, which is used to fix the seat ring or the top cover set during the subsequent installation process. In contrast to the prior art, in the case of the sanitary device according to the invention, the two threaded holes of the first fixing device can be accessed from above through the two wall openings.

[0010] The accessibility described above is achieved during the entire installation process of the sanitary ware, because according to the invention two specially designed second fixing devices are used, which are able to fix the seat ring or the top cover set. Each second fixing device consists of multiple parts and, on the one hand, comprises a sleeve with a perforation extending through it, wherein the sleeve passes through the corresponding wall opening and is fixed to the wall with the wall opening by suitable fixing members. Before the sanitary ware is installed, these sleeves are already fixed to hanging bolts on the wall of the sanitary ware. In addition, each second fixing device comprises a retaining pin that can be releasably connected to the sleeve. The retaining pins are only fixed when the sanitary ware is fixed in a hanging manner, that is, shortly before the seat ring or the top cover set fixed to the two retaining pins is fixed.

[0011] The composite solution according to the invention of the second fixing device, which comprises a sleeve and a separate retaining pin respectively, has many advantages. On the one hand, as mentioned above, the two sleeves are already fixed at the upper rear wall before the sanitary ware is installed on the wall. In this way, the two sleeves can be accurately positioned and aligned in the corresponding wall openings, because these sleeves are firmly connected to the wall and determine the subsequent installation position of the two retaining pins. These wall openings have a correspondingly large diameter of 1-2 cm in order to achieve the corresponding seat ring or cover orientation. Because the seat ring or cover kit must be accurately aligned relative to the sanitary ware during installation, so that it does not deviate forward or to the side, but is symmetrically positioned. For this purpose, after the diameter of the sleeve is smaller than the diameter of the wall opening, the two sleeves are accurately positioned in their position by sliding in the corresponding wall opening. On the other hand, the two sleeves are also spaced at an accurate distance from each other. However, using the second fixing device according to the invention, the accurate positioning of the sleeves with determined positions can be smoothly achieved and can be achieved at the factory, that is, the two sleeves are already fixed in accurate alignment at the factory, so that the assembler does not need to do this work again. With the sanitary ware suspended, the fitter only has to secure the two retaining pins to the sleeves in order to subsequently place the seat ring or the top cover kit.

[0012] Thus, through the axial perforation in the sleeve, the assembler can enter the interior of the sanitary ware from above through the upper wall and engage with the retaining screws with the aid of a suitable tool (such as a screwdriver), which of course also face the upper wall since the threaded holes face the upper wall. Thus, when the first fixing device is sleeved onto the two retaining bolts, the assembler can easily tighten the retaining screws from above through the two sleeves and fix the sanitary ware to the wall-side retaining bolts. At the same time, the assembler does not have to worry about the exact alignment of the seat ring or the top cover set during the subsequent installation process, because the two separate sleeves are preferably already accurately aligned at the factory or have been accurately aligned by the assembler on site before safety. The assembler only needs to fix the two retaining pins on the sleeves and place the seat ring or the top cover set, and the seat ring or the top cover set will automatically be optimally aligned.

[0013] The sanitary fitting according to the invention therefore offers a very simple installation overall, since the fitter no longer has to laboriously reach into the interior of the sanitary ware from below to tighten the retaining screws, since this installation step can be easily done from above via the two sleeves. Furthermore, the fitter is also relieved when installing the seat ring or the cover kit, since he does not have to carry out any tedious alignment work when installing the kit.

[0014] In a further embodiment of the invention, it can be provided that the sleeve has an external threaded section, wherein a first and a second thrust bearing element are provided, which in the installed position accommodate a section of the sanitary ware between them and are tensioned relative to the section, and at least one nut is provided to be screwed onto the external threaded section for tensioning the thrust bearing element and the sleeve. To install the fixture, the sleeve is first pushed through the perforation in the sanitary ware and the first thrust bearing element is positioned on the inside of the sanitary ware, the second thrust bearing element is positioned on the outside or top side of the sanitary ware, and then the nut is screwed onto the external threaded section of the sleeve that is accessible from the inside of the ceramic, and the ceramic section located between the thrust bearing elements is tensioned between the thrust bearing elements by the nut. In the installed position, the sleeve is almost flush with the second thrust bearing element, while the second thrust bearing element rests on the top side of the ceramic and ultimately only protrudes slightly beyond the top side of the ceramic or is flush with it. In any case, a sleeve installed in this way does not protrude significantly from the top side of the ceramic. This is preferably done in the factory, before the sanitary ware is installed, in the manner described above.

[0015] As mentioned above, the retaining pin is connected to the sleeve only at the end of the installation. In order to achieve this simply, it can be provided in a modified version of the invention that the perforation of the sleeve is provided with an internal thread at least in sections, and the retaining pin has an external thread section to be screwed into the internal thread of the perforation. A very simple fixation of the corresponding retaining pin can be achieved by this screw connection, wherein, as mentioned above, the retaining pin is optimally positioned based on the precise orientation of the two sleeves in the corresponding wall openings and relative to each other. Only when the seat ring or the top cover kit can actually be installed, the retaining pin is screwed with its external thread into the internal thread hole of the sleeve that can be accessed from the top side of the ceramic, so that the second fixing device is finally complete and forms a fixing section protruding on the top side with the retaining pin, and then the kit-side fixing element can be plugged into the fixing section.

[0016] In a refinement of the invention, the sleeve can have a support section by means of which the sleeve can be tensioned relative to the second thrust bearing element when the nut is screwed on. The sleeve is placed and supported on this side of the second thrust bearing element by means of the support section. The second thrust bearing element is thus a separate component. As an alternative, the second thrust bearing element can be formed in one piece with the sleeve. The sleeve thus has an end flange or boss which projects radially and is supported on the top side of the sanitary ware in the installed position in such a way as to form the second thrust bearing element.

[0017] The first thrust bearing element or the first and second thrust bearing elements are preferably implemented as disks or plates. These thrust bearing elements are dimensioned accordingly in terms of their diameter, width or length to ensure that sufficient support is always achieved on the sanitary ware, no matter in which final position the sleeve is arranged.

[0018] In this case, the first and / or second thrust bearing element can also be held inseparably on the sleeve. This facilitates installation, since the respective thrust bearing element held inseparably does not need to be handled or positioned separately. The second thrust bearing element resting on the top side of the wall is particularly advantageously held inseparably, which can be achieved, for example, by riveting or gluing. However, as already mentioned above, the second thrust bearing element can also be formed integrally with the sleeve, i.e. as a protruding flange, so that in this case, no separate thrust bearing element needs to be fixed.

[0019] In any case, the first thrust bearing element is a separate component. The first thrust bearing element can be implemented as a separate disk or plate as described above, and during the installation process, when the sleeve is inserted through the perforation, the first thrust bearing element can also be plugged onto the sleeve from the inside of the ceramic and fixed by means of a nut. In this regard, an advantageous alternative of the invention is that the first thrust bearing element has a longitudinal slit for the sleeve to pass through, so that the thrust bearing element can be tilted towards the sleeve. This technical solution can be put on the sleeve and fixed by means of a nut before the sleeve is installed as a toggle bolt. For installation, the first thrust bearing element should be moved into the installation position, in which the first thrust bearing element is tilted towards the sleeve. In this position, the device composed of the sleeve and the first thrust bearing element has a narrow shape and can be guided through the perforation. Subsequently, the first thrust bearing element automatically tilts again, that is, it protrudes from the sleeve on both sides and is clamped behind the sanitary ware, so that the sanitary ware is tensioned relative to the first thrust bearing element when the nut is tightened. This tilting solution is achieved by constructing corresponding longitudinal seams.

[0020] If a support section is provided on the sleeve, i.e. a separate second thrust bearing element is used, this support section is advantageously realized by a radially protruding, circumferential boss or flange arranged at the end of the sleeve, with which the sleeve rests on the second thrust bearing element. The boss can be implemented in a relatively thin manner, since it only serves a supporting function but does not bear any other loads during operation. In this regard, the second thrust bearing element particularly preferably has a recess for accommodating the boss in a buried manner. This ensures that when the boss is arranged at the end of the sleeve and accommodated in a buried manner, the sleeve is ultimately flush with the second thrust bearing element, i.e. the disk or plate, and therefore does not protrude at all from the thrust bearing plane. The boss can, for example, be conical, while the recess has a shape-matching depression. In addition, a stepped recess can also be used, into which the boss or flange snaps into place in a shape-fitting manner.

[0021] As described above, the fixing device is reversed on the bottom or inside by a nut screwed onto the external threaded section. In order to be able to tension these elements axially accordingly, an advantageous improvement of the present invention proposes that the sleeve has a receptacle for placing a tool, through which the nut can be engaged with the tool and with the sleeve by another tool, so that only the sleeve is fixed when the nut is screwed, or the nut is fixed and the sleeve is actively screwed or the nut and sleeve are screwed accordingly. For this purpose, the receptacle can be implemented as a slit arranged at the end side of the sleeve, into which the slit can be engaged by means of a screwdriver. As an alternative, the receptacle can also be implemented as a polygonal recess extending into the internal threaded hole, i.e., for example, as an internal hexagon for accommodating an internal hexagonal wrench. The polygonal recess extends into a cylindrical perforation or drilled hole, i.e., (if any) into the internal threaded hole.

[0022] The second thrust bearing element (either as a separate component or as an integrated sleeve component) is arranged on the surface of the sanitary ware, which is usually covered with glaze. In order to avoid scratches on the glaze during installation, surface protection can be provided. For this purpose, the second thrust bearing element can have a stop section made of a softer material (such as a plastic material) that rests on the sanitary ware. Therefore, the second thrust bearing element can be provided with a plastic coating on one side, for example sprayed or glued on. The plastic section, which is significantly softer than the metal used to make the second thrust bearing element, can effectively prevent direct contact between the metal and the glaze and avoid scratches. As an alternative, the second thrust bearing element can also be supported on the sanitary ware by a stop washer, for example made of a plastic material. That is to say, the softer stop washer is first placed on the glaze surface, and then the second thrust bearing element. Therefore, direct contact between the glaze and the metal is also avoided here.

[0023] As mentioned above, only during the final installation of the seat ring or the cover set is the respective retaining pin fixed to the nail sleeve, for example screwed into the internal threaded hole by means of its external thread. In order to be able to tighten the retaining pin sufficiently and thus prevent accidental loosening, the retaining pin advantageously has a receptacle for placing a tool. Such a receptacle can be, for example, a slot provided at the end of the retaining pin, into which the screwdriver can be engaged. The retaining pin can also be a polygonal pin segment, which can be engaged with an open-end spanner.

[0024] The retaining pin itself advantageously has one or more clamping or locking elements for clamping or locking the seat ring set. Such clamping or locking elements can be, for example, clamping rings made of plastic or metal that snap into the grooves on the retaining pin sides, and whose outer diameter is slightly larger than the through holes or blind holes on the fixing elements of the seat ring set. However, it is also possible to provide only the pin-side grooves as such clamping or locking elements, and during plug-in, the locking elements provided on the fixing device of the seat ring or the cover set snap into the grooves.

[0025] Furthermore, a protective cover can be provided, which is placed on the second thrust bearing element in the installed position in such a way that it covers it and through which the retaining pin passes. That is, in the case where the second thrust bearing element is designed as a circular disk or a circular flange, the protective cover, which is also correspondingly circular, covers the second thrust bearing element. The protective cover can also have a corresponding sleeve-shaped section, into which the retaining pin partially engages, so that the retaining pin is also approximately hidden, as long as the retaining pin is not engaged in the fixing device of the seat ring set. Furthermore, the fixing device of the seat ring set can also be supported on the protective cover, for which purpose the protective cover can be designed, for example, in a rounded manner at the upper end if the inserted section of the fixing device on the set side has a cylindrical outer shape, so that an almost form-fitting accommodation is achieved.

[0026] In a further development of the invention, it can be provided that the first fixing device has two holding sections, by means of which the first fixing device can be fixed in or on one or more holding receptacles provided on the sanitary ware. The two holding sections enable corresponding holding geometries to be realized on the first fixing device, which interact with correspondingly designed or shaped holding receptacles in order to fix or secure the first fixing device to the sanitary ware. In the case of corresponding plug-in or clamping geometries provided at the holding receptacles, the holding sections can be designed as plug-in sections or also as clamping sections.

[0027] According to a first inventive variant, it can be provided that the first fixing device is designed in the form of an arm, wherein a holding section is provided at each end, which is snapped into a holding receptacle provided on the sanitary ware. In this case, the fixing device is an arm-shaped component, at the ends of which two holding sections are provided, which are preferably implemented as simple plug-in sections, in particular with a cylindrical cross section. The holding receptacle on the sanitary ware is correspondingly implemented in a shape-compatible manner so that the end-side holding section can be inserted or pushed into the holding receptacle. The holding receptacle is preferably a blind hole without an outward opening, i.e. the side wall of the sanitary ware is not perforated, but the first fixing device is only fixed inside and is therefore not visible. Since the weight of the sanitary ware is supported on the holding bolt by the first fixing device, whether directly on the suspension bolt or on a holding sleeve screwed onto the suspension bolt, the first fixing device is preferably made of metal.

[0028] It is particularly advantageous if the first fixing device is composed of at least two arm sections that can be fixed to one another in different positions, each of which has a retaining section. The arm-shaped fixing device can thus be telescopic and thus its length can be varied, which is advantageous for installation. If the retaining section is implemented, for example, as a cylindrical end with a circular cross section and the retaining receptacle is implemented as a cylindrical blind hole, in the case of a telescopic embodiment of the first arm-shaped fixing device, the corresponding arm sections can first be pushed together for installation, so that the fixing device is correspondingly shorter. During installation, the fixing device is positioned and pushed apart from one another so that the retaining sections are inserted into the retaining receptacle and then the arm sections are fixed to one another again. For this purpose, one or more screw connections are used, for example, which engage through corresponding slots or similar holes provided in the arm sections.

[0029] Furthermore, the first fixing device can include two spring elements, by means of which the first fixing device is tensioned in the holding receptacle. The two spring elements tension the fixing device on both sides on the one hand and center the fixing device on the other hand.

[0030] According to a second inventive variant, the first fixing device may include two independent fixing devices, each of which is individually fixed or can be individually fixed to the sanitary ware, and each fixing device has a retaining bolt receiving portion. In the first inventive variant, a single component is generally provided as the first fixing device, while according to the second variant, the first fixing device is composed of multiple parts, including two independent fixing devices, each of which is fixed to the sanitary ware. Each fixing device has a corresponding retaining section, and may also have multiple retaining sections, wherein a corresponding retaining receiving portion is constructed on the sanitary ware. Each retaining device also has an independent retaining bolt receiving portion, in which the retaining bolt is inserted or passes through the retaining bolt receiving portion. Of course, each retaining bolt receiving portion also corresponds to a corresponding threaded hole for accommodating a retaining screw, wherein in this variant, these threaded holes are of course also facing the upper wall or wall opening in the installed position.

[0031] In this variant, each fastening device can have a guide section as a holding section, with which, in the installed position, the fastening device snaps into a guide receptacle provided on the sanitary ware and forming a holding receptacle. Here, the installation takes place by simply pushing it in, wherein the fastening element designed in the form of a linear guide also simultaneously provides an anti-twist protection. In this case, in the pushed-in end position, the threaded holes are automatically oriented upwards.

[0032] Finally, the first fixture may comprise two guide sleeves in which the retaining screws are received in the mounted position. On the one hand, during the mounting of the fixture on the sanitary ware, these guide sleeves protect the retaining screws, which retaining screws are of course advantageously screwed into the threaded holes during pre-installation, since, as mentioned above, when the fixture is mounted, these retaining screws face upwards towards the upper wall or the wall opening, and subsequent insertion may be more cumbersome. In addition, these guide sleeves can also be used to guide a tool (i.e. a screwdriver) inserted through the corresponding sleeve so that it is substantially automatically guided to the screw head and can engage the screw head. Each guide sleeve can have a narrower diameter region of the ring screw shank and a funnel-shaped section adjacent thereto, into which the screwdriver engages and through which it is guided to the screw head.

[0052] Figure 1 1 is a partially cutaway side view of a sanitary device 1 according to the invention. It shows a sanitary fixture 2 in the form of a toilet bowl 3 to be hung on a vertical wall, which toilet bowl 3 is shown in a partially cutaway manner in its rear end region. The toilet bowl 3 has a rear wall 4 which is horizontal in the installed position and in which two wall openings 5, for example in the form of circular boreholes, are provided. The wall openings 5 ​​are each used to fasten a second fastening device 6, Figure 1 and Figure 2 A portion of the second fixing device is shown. The second fixing device 6 is used to fix a seat ring or a cover kit placed on the wall 4 from above.

[0053] Each second fixing device 6 ( Figure 1 and Figure 2 Only a part of the device components is shown in the figure) each comprises a sleeve 7, which has an external thread section 8, wherein the sleeve 7 is engaged in the installation position through the corresponding wall opening 5. In addition, a nut 9 that can be screwed onto the external thread section 8 is also provided.

[0054] Furthermore, a first thrust bearing element 10 in the form of a dish-shaped disk and a second, plate-shaped thrust bearing element 11 are provided, which has a recess 12 into which a radially protruding boss 13 engages in a form-fitting manner in the installed position, which serves as a support section for the sleeve 7 and supports it relative to the wall 4 or the thrust bearing element 11. The diameter of the two thrust bearing elements 10, 11 is greater than the diameter of the corresponding wall opening 5, so that the two thrust bearing elements can clamp the wall 4 between them.

[0055] In order to mount the corresponding fixing device 6 including the retaining pin 25 to be connected to the sleeve 7 (which will be explained below), the sleeve 7 is first inserted through the second thrust bearing element 11 until the boss 13 snaps into the recess 12. The sleeve 7 is then guided through the wall opening 5 by means of the external thread section 8, the first thrust bearing element 10 is then inserted and the nut 9 is subsequently screwed onto the external thread section 8 until the device part is firmly tensioned on the wall 4. In this case, the first thrust bearing element 10, which is designed as a disk, is deformed and prestressed, which ensures the screw connection. The installation position is Figure 4 and Figure 5 It is shown that although Figure 2-4 Only one occupied wall opening 5 is shown, the described components of the second fastening device 6 being of course fastened in each wall opening 5 .

[0056] Figure 6 FIG. 3 is a rear view of a toilet bowl 3 on which the individual components of a second fixing device 6 are tensioned in two wall openings 5. Figure 6 In the next step, the first fixing device 14 is fixed to the sanitary ware 2, here to the toilet bowl 3. The first fixing device 14 is designed in the form of an arm and consists of two arm sections 15, which can be fixed to each other in different positions, for example screwed together, in order to change the length of the second fixing device 14.

[0057] The second fixing means 14 each have a holding section 16 at its ends. Figure 6 In the installation position shown, the retaining section is engaged in the form of a blind hole on the sanitary ware 2. Figure 6 In the corresponding holding receptacle 17 shown in dashed lines in FIG. For tensioning or centering, spring elements in the form of helical springs, not shown in detail, can also be provided, which are placed on the two holding sections 16 and supported on the sanitary ware on the one hand and on the corresponding arm section 15 on the other hand.

[0058] The second fixing device 14 is used to fix the sanitary ware 2 to two retaining bolts arranged on the wall side, which will be explained below. To this end, the arm-shaped second fixing device 14 has two retaining bolt receiving parts 18, for example, with a circular cross-section. In the installed position, these two retaining bolt receiving parts are respectively engaged with the retaining bolts to firmly connect the first fixing device 14 with the retaining bolts. Each retaining bolt receiving part 18 has a corresponding threaded hole 19, wherein the corresponding threaded hole 19 is connected to the corresponding retaining bolt receiving part 18. Figure 6 In the illustrated mounting position, a retaining screw 20 has been screwed into each threaded hole 19. In this case, the two threaded holes 19 are arranged so that they face upward toward the wall 4, preferably oriented so that they face directly toward the wall opening 5 and thus also toward the respective second fixing device 6.

[0059] Figure 6 and Figure 7 Also shown are two guide bushings 21 which are arranged on or in the retaining bolt receptacles 18 and which facilitate the sliding onto retaining bolts 24 , described below, which are arranged on the vertical wall 30 .

[0060] from Figure 6 and Figure 7 The orientation of the two threaded holes 19 and the retaining screws 20 relative to the upper wall 4 and the part of the second fastening device 6 which is tensioned there can be seen. Figure 7 It is also shown that the corresponding sleeve 7 has a perforation 22 which passes through the entire sleeve 7 so that the perforation 22 is open both on the top side and on the bottom side of the wall 4. This makes it possible to guide a tool 23 (for example Figure 8The hexagonal wrench shown in FIG. 2 is passed through the through hole 22. Figure 8 and Fig. 9 As shown, the tool 23 engages with the corresponding retaining screw 20. During the installation process, after the first fixing device 14 is positioned, the sanitary ware 2 is sleeved onto the retaining bolt 24 arranged on the wall side. The retaining bolt 24 can be, for example, a hanging bolt protruding from the wall side, or can be a sleeve-shaped retaining bolt screwed onto such a hanging bolt. In order to fix the sanitary ware 2 on the retaining bolt 24, the corresponding retaining screw 22 is screwed into the internal thread 19 by means of the tool 23 until it is screwed onto the retaining bolt 24 that is engaged with the retaining bolt receptacle 18 and is firmly tensioned in the retaining bolt receptacle 18. In other words, the sanitary ware 2 can be fixed to the retaining bolt 24 only by simple tool contact from above through the wall 4, because the corresponding second fixing device 6 is composed of multiple parts and is still continuous in this installed state, that is, the through hole 22 is still open. The screw 20 can be accessed from above because, as mentioned above, the threaded hole 19 together with the screw 20 is facing upward, preferably directly toward the corresponding through hole 22.

[0061] If the sanitary ware 2 is fixed to the wall-side retaining bolts 24, the two second fixing devices 6 are matched in the next step. Each fixing device 6 comprises a retaining pin 25, which has a widened collar 26 with an external thread section 27 at one end. The corresponding sleeve 7 is provided with an internal thread 28 in the region of its through-hole 22, into which the external thread section 27 of the corresponding retaining pin 25 can be screwed. This assembly step is Fig.10 and Fig.11 Shown. Fig.12 and Fig.13 In the illustrated installation position, the two retaining pins 25 protrude upward, i.e., from the wall 4, and serve to receive a seat ring or a cover assembly, which is plugged onto the retaining pins 25 from above in a simple manner and clamped or locked there. In order to tighten the respective retaining pin 25, each retaining pin 25 has a receptacle 29, for example a flattened portion on both sides, so that it can be engaged with a wrench in order to tighten the retaining pin 25.

[0062] Fig.13 A corresponding sectional view is shown, which shows how the retaining pin 25 with the widened collar 26 is screwed into the sleeve 7. The through-hole 22 in the sleeve 7 is now closed. In the event that the sanitary ware needs to be disassembled, it is only necessary to unscrew the corresponding retaining pin 25 from the sleeve 7 again, so that the through-hole 22 is opened again and the retaining screw 20 can be accessed again with the help of a tool to release the tension with the corresponding retaining bolt 24.

[0063] Fig.14The sanitary ware 2, i.e. a toilet bowl 3, is shown in its final installation position, wherein, on the one hand, the sanitary ware is securely fastened to the retaining bolts 24 at the vertical wall 30, and, on the other hand, the two second fixing devices 6 are already complete and their retaining pins 25 protrude upward from the wall 4 so that the corresponding seat ring or cover kit can be simply plugged in from above.

[0064] Figure 15-18 It is a partial view of the main components of the second fixing device 6. Fig.15 7 is a perspective view of the sleeve 7. The figure shows the external thread section 8 as well as the boss 13 and the through-hole 22. At the end of the through-hole 22 that is connected to the boss 13, a polygonal recess 31 is provided on the one hand, which is used to accommodate a tool, such as an Allen wrench, so that the sleeve can be fixed and tightened there, which is necessary for tightening the nut 9 when it is necessary to tension the component on the wall 4 in the wall opening 5. At the same time, an internal thread 28 is formed in the area of ​​the polygonal recess 31, into which the external thread section 27 of the retaining pin 25 is screwed.

[0065] Fig.16 The second thrust bearing element 11 is shown with its recess 12 , in which the boss 13 is received in a form-fitting and surface-flush manner.

[0066] Fig.17 2 is a perspective view of a retaining pin 25 with a collar 26 and an external threaded section 27 and a tool receptacle 29. The figure also shows a clamping element 32 in the form of a clamping ring received in a groove for clamping to fix the seat ring or cover set placed therein. The set has, for example, two rotation damping devices, each of which can be operatively connected to one of the retaining pins 25. These rotation damping devices each have a rotation damper, which has a corresponding component with a through hole, wherein the component with the through hole is plugged onto the retaining pin 25 and clamped there.

[0067] at last, Fig.18 Shown in partially plugged state Figure 15-17 The second thrust bearing element 11 is sleeved onto the sleeve 7, and the retaining pin 25 is screwed into the sleeve 7 or its through hole 22. Figure 2 It is depicted in the drawings but not shown in detail that each second fixing device also comprises a first thrust bearing element 10 in the form of a dish-shaped disk and a nut 9 which bears against the underside of the wall 4 in the installed position.

[0068] There may also be a plastic disc which is placed between the top side of the wall 4 and the bottom side of the second thrust bearing element 11 in order to protect the surface of the wall 4. Instead of a separate plastic disc, there may also be a plastic coating of the bottom side of the second thrust bearing element 11.

[0069] Furthermore, it is also possible to design the second thrust bearing element 11 in one piece with the sleeve 7, i.e. to enlarge the diameter of the boss 13 accordingly, so that the boss 13 serves as a second thrust bearing element and bears on the top side of the wall 4. However, the diameter of the second thrust bearing element 11, whether a separate thrust bearing element or a thrust bearing element formed in one piece with the sleeve 7, is always dimensioned such that its diameter is significantly larger than the diameter of the corresponding wall opening 5, so that the position of the sleeve 7 in the wall opening 5 can be oriented accordingly and the two fixing devices 6 in the two wall openings can be oriented accordingly relative to each other, so that the wall opening 5 is always covered. This is because it must be ensured that the two retaining pins 25 are positioned exactly so that the seat ring or cover set placed is positioned exactly relative to the sanitary ware 2.

[0070] In addition, a protective cover can also be provided. After the corresponding second fixing device is fully assembled, the protective cover is placed on the second fixing device from above, and the protective cover covers the second thrust bearing element 11 on the one hand, and accommodates the retaining pin 25 by means of the sleeve section on the other hand, so that the second thrust bearing element and the retaining pin are no longer visible.

[0071] Finally, two additional guide sleeves can also be provided, which are arranged in the extension of the threaded hole 19 and are used to guide the tool. These guide sleeves are advantageous when the fixing screw 20 is relatively short and is designed as a headless screw, for example. The tool can be guided as well as possible to the corresponding retaining screw by means of these guide sleeves.
