Description

[0001] The present invention relates to a wall mounting for a sanitary article, such as a toilet bowl. It relates in particular to a wall mounting for a wall-hung sanitary article.

[0002] Wall-hung sanitary ware is typically mounted using a wall bracket that is operated from below and allows the sanitary ware to be positioned flush against the wall. Most of the parts required for mounting are visually concealed by the sanitary ware itself. WO2009 / 074301 A1 discloses a wall bracket that can be operated from above. In this bracket, a locking nut is guided along an inclined track in the wall bracket by means of a screw that is tightened from above, simultaneously pulling the wall-hung sanitary ware against the wall. Another wall mounting method is disclosed in WO2022 / 103353, in which a slider on an inclined surface of a wall bracket can be adjusted by means of a screw.

[0003] Aspects of installing a sanitary ware include the accessibility of a fixing point, as well as a support for the sanitary ware during installation.

[0004] The object of the present invention is to provide a wall mounting that enables simple and easily accessible installation of the sanitary ware. Furthermore, the wall mounting should allow for the loose pre-assembly of a sanitary ware, which simplifies its installation.

[0005] The invention relates to a wall mounting for a sanitary article, for example a toilet bowl, a bidet, a urinal, a washbasin, etc.

[0006] The wall mounting bracket has a support surface for a sanitary fitting and a through-hole for a mounting screw, allowing the sanitary fitting to be screwed to the wall mounting bracket from above and attached to a wall. The wall mounting bracket has a locking nut for interaction with a mounting screw, which locking nut is mounted in a slide mechanism to prevent rotation. The wall mounting bracket further has a slide sleeve that receives the mounting screw, the lower end of which is slidably mounted on a sliding surface of the wall mounting bracket that is inclined downwards towards the wall-side end.

[0007] When the sliding sleeve is pressed downwards via the mounting screw, its lower end acts on the inclined sliding surface of the wall bracket. Since the wall bracket is first securely attached to the wall, the force exerted on the sliding surface acts on the locking nut. This nut is, however, mounted in the slider to prevent rotation, thus pushing the slider towards the wall. This movement towards the wall, via the sliding sleeve, acts on a sanitary fitting, which is attached to the wall mounting. This allows a sanitary fitting, for example, along the entire length of a through-hole in a sanitary fitting such as a ceramic fixture, to be moved against a wall and then secured in the wall-mounted position.

[0008] This type of force transmission and corresponding direction of movement of a sanitary fitting is achieved because the sliding surface is inclined downwards on the wall side. Accordingly, the upper end of the sliding surface is positioned towards the free end of the wall bracket. This offers a further advantage during installation. When a sanitary fitting is slid over the free end of the wall bracket during installation, and a sliding sleeve is inserted from above through a through-hole in the fitting, the lower end of the sliding sleeve is automatically positioned below the upper end of the sliding surface. The lower end of the sliding sleeve is thus within the engagement area of ​​the wall bracket. To remove the sanitary fitting from the wall bracket, the sliding sleeve would therefore have to be lifted back over the upper end of the sliding surface.

[0009] This simplifies the installation of a sanitary fixture. Once placed on the wall bracket, it no longer needs to be held in place, as it is secured by the sliding sleeve located within the bracket's engagement area. A fixing screw is not required for this type of pre-assembly. A fixing screw is preferably inserted into the sliding sleeve only after the sanitary fixture has been placed on the wall bracket, i.e., after pre-assembly.

[0010] Preferably, the lower end of a slide sleeve is chamfered. The chamfer of the end preferably corresponds to an inclination of the inclined slide surface. The chamfered lower end of the slide sleeve typically runs parallel to and along the slide surface. This allows the slide sleeve to be guided along the slide surface with its entire lower end. Force transmission from the slide sleeve to the slide surface can thus be distributed over a larger area than, for example, a non-chamfered end or the end of a fastening screw. The size of this area can be varied by the diameter of the slide sleeve and the inclination of the chamfer at its lower end.

[0011] Preferred angles of inclination for a sliding surface and a chamfered lower end of a sliding sleeve are in a range of 25 degrees to 60 degrees, preferably 30 degrees to 50 degrees, for example between 38 degrees and 45 degrees with respect to a horizontal.

[0012] Inclination values ​​of the slide surface and the beveled lower end of the slide sleeve in these angular ranges indicate good force transmission from the slide sleeve to the slide surface.

[0013] A lower end of a slide sleeve, in particular a chamfered lower end of a slide sleeve, and a slide surface preferably exhibit good (mutual) sliding properties. For this purpose, the slide sleeve, at least a lower end of the slide sleeve, and / or the slide surface are preferably made of or coated with a material that slides well. This could, for example, be a plastic with good sliding properties.

[0014] A sliding sleeve is hollow inside and has a through opening for receiving a fastening screw. The sliding sleeve also has an internal stop for the screw head of a fastening screw, so that the screw can be inserted into the sleeve but cannot fall out again downwards. This internal stop is preferably circumferential.

[0015] The external shape and size of a slide sleeve is preferably adapted to the shape and inner diameter of a through-hole in a sanitary article.

[0016] The outer circumference of a slide sleeve is preferably round, or mostly round.

[0017] Preferably, the outer circumference of a valve sleeve corresponds substantially to the inner diameter of a through-hole in a sanitary fitting, such that the valve sleeve can be moved within the through-hole with minimal play. If both the outer diameter of the valve sleeve and the inner diameter of the through-hole are round, the inner diameter of the through-hole is preferably 0.5 percent to 20 percent larger than the outer diameter of the valve sleeve.

[0018] A sliding sleeve preferably has an anti-rotation feature. This makes it possible to position the sliding sleeve in the wall bracket in such a way that it is optimally positioned as soon as it is inserted. This is particularly advantageous for a sliding sleeve with a beveled lower end, as the beveled end can then be positioned directly against a sliding surface.

[0019] A passage in the wall bracket for receiving a fastening screw runs through the inclined sliding surface. The fastening screw can be inserted through the sliding surface and into the locking nut located below in the slide.

[0020] The passage has a larger lateral extent, preferably a larger diameter, in the receiving surface than in the sliding surface. In particular, the passage in the sliding surface has a smaller diameter than the outer diameter of a sliding sleeve. A passage in the sliding surface has a sufficiently large inner diameter to accommodate a suitable fastening screw.

[0021] This ensures that the slide sleeve can be guided into the opening in the receiving surface, but will abut against the slide surface. A fastening screw passed through the slide sleeve can, however, be guided through the slide surface and into the locking nut provided below in the slide, where it can be screwed in.

[0022] Preferably, the wall bracket further comprises an inclined positioning surface. The positioning surface extends upwards towards the wall-side end of the wall bracket. Preferably, a positioning surface is arranged at a free end of the wall bracket. This free end of the wall bracket is positioned opposite the wall-side end of the wall bracket.

[0023] A positioning surface facilitates the installation of a sanitary fitting onto a wall bracket. During wall mounting, a sanitary fitting equipped with a sliding sleeve is pushed onto the bracket from the free end. The lower end of the sliding sleeve, which is inserted into a through-hole in the sanitary fitting and protrudes downwards, then contacts the positioning surface. The inclined positioning surface allows the lower end of the sliding sleeve to slide along it. The sliding sleeve is guided along the positioning surface and pushed upwards out of the through-hole, ensuring that its lower end does not become jammed or bent when the sanitary fitting is slid onto the wall bracket.Furthermore, the movement of the sliding sleeve during the assembly process can visibly indicate from the outside how far a sanitary article has already been pushed over or onto a wall bracket, whether it is in a pre-assembly position and whether it can be released accordingly.

[0024] In preferred embodiments of a wall mounting, the upper end of a positioning surface and the upper end of a sliding surface are arranged adjacent to each other. Preferably, the sliding sleeve, guided on and along the positioning surface, slides upwards to the upper end of the positioning surface. As the sliding surface engages with the positioning surface, the sliding sleeve is guided downwards again towards the wall when a sanitary fitting is further pushed onto the wall bracket, due to the downward slope of the sliding surface on the wall side. This allows the sliding sleeve to be guided into an engagement position and the sanitary fitting to be brought into a held pre-assembly position.

[0025] To secure a sanitary fitting in such a pre-assembled position, the upper end of the inclined sliding surface can transition into a vertical section. Since the sliding surface is inclined downwards on the wall side, its upper end is positioned towards the free end of the wall bracket. This vertical section thus acts as a stop for the sliding sleeve, as the sleeve would have to be lifted over this section to remove the sanitary fitting from the wall bracket in its pre-assembled position. This further simplifies the installation of a sanitary fitting, as once it is placed on the wall bracket, it no longer needs to be held and is secured against unintentional detachment.

[0026] In preferred embodiments, the positioning surface and the sliding surface are arranged adjacently, such that the vertical section forms an offset, preferably vertical, between the upper end of the positioning surface and the upper end of the sliding surface. Such an offset offers advantages not only with regard to pre-assembly securing. The offset also clearly indicates, from the outside, when a sanitary fitting is in a pre-assembly position, via the sliding sleeve suddenly falling due to the offset.

[0027] A sliding mechanism mounted in a wall bracket is primarily intended for pushing a sanitary fixture towards the wall. Accordingly, the fastening force acting on the wall mounting is redirected as directly as possible via the fastening screw to the sanitary fixture being attached to the wall. This force therefore preferably acts perpendicular to the wall.

[0028] Accordingly, a slider is preferably arranged to be displaceable exclusively horizontally in order to transfer a force acting on the slider as directly as possible to the article to be attached to a wall.

[0029] A slider is preferably arranged to be slidable along a horizontal guide in the wall bracket.

[0030] A slider can be fitted with a locking nut and be movable but fixed in the wall bracket.

[0031] Preferably, a sliding mechanism is a separate element. Preferably, a wall bracket can be fitted with the sliding mechanism before or after its wall mounting. This offers the advantage that wall brackets can be designed for different types of mounting screws.

[0032] Preferably, a slider can be inserted into a wall bracket. Preferably, a slider can be inserted into the wall bracket via a free end of the wall bracket, which is opposite a wall-side end of the wall bracket. This offers the advantage that a wall bracket can be attached to a wall, and the slider can be fitted to the wall bracket subsequently.

[0033] A guide for a slide in a wall bracket can be designed in various ways. Preferably, a guide for the slide in the wall bracket has at least one rail, a dovetail guide, or a groove and rib. For example, a rail can be provided only in the wall bracket, only in the slide, or in both the wall bracket and the slide.

[0034] Preferably, the wall mounting incorporates locking devices to secure the slider within the wall bracket. These locking devices prevent the slider from unintentionally detaching from or falling out of the wall bracket, as can occur, for example, after the slider has been attached to the wall bracket or during the mounting of the wall bracket to a wall. Such locking devices can be, for example, simple positive locking mechanisms, snap locks, or friction locks. Additionally, the locking devices can serve to position the slider in a defined position within the wall bracket at the start of installation, particularly in a defined position relative to the slider sleeve and / or the mounting screw.

[0035] To attach a wall bracket to a wall, the bracket preferably has a mounting hole at its wall-side end for inserting a mounting bolt. The wall bracket can be attached to the wall using the mounting bolt, which is already fixed in the wall. The mounting hole in the wall bracket preferably has a thread that engages with a corresponding thread in the mounting bolt.

[0036] Preferably, all elements of the wall mounting, except for the actual fastening elements such as the mounting screw and locking nut, are made of plastic or fiber-reinforced plastic. Fastening elements such as the mounting screw and locking nut are preferably made of metal. Additional metal elements may be provided for reinforcement. For example, a metal cage for receiving a mounting screw head may be incorporated into the sliding sleeve.

[0037] The invention further relates to a sanitary article with a wall mounting according to the invention and as described herein. The sanitary article rests on a support surface of a wall bracket, and a sliding sleeve of the wall mounting is inserted into a through-hole in a top surface of the sanitary article.

[0038] Preferably, the sanitary article has an anti-rotation device for the valve sleeve in the through-hole. The anti-rotation device can have anti-rotation elements located exclusively in the through-hole or exclusively in the valve sleeve. Preferably, an anti-rotation device has cooperating anti-rotation elements located both in the through-hole and in the valve sleeve.

[0039] For example, an anti-rotation device can be implemented as a shoulder in a through hole and as a corresponding undercut in an outer circumference of the slide sleeve.

[0040] Preferably, the outer circumference of a slide valve sleeve corresponds substantially to the inner diameter of a through-hole in a sanitary fitting, such that the slide valve sleeve can be moved within the through-hole, but can be inserted into the through-hole as precisely as possible. Furthermore, shapes for the slide valve sleeve and through-hole are possible which, due to their form, prevent the slide valve sleeve from rotating within the through-hole. For example, but not exclusively, this can be achieved by an oval outer contour or a rectangular contour, preferably with rounded corners, for a slide valve sleeve and correspondingly appropriate inner diameters of a through-hole. In particular, shapes can be selected that define a specific position, i.e., are "shape-coded".

[0041] In preferred embodiments of the sanitary article, a through-hole is used for attaching a toilet seat. Accordingly, an upper end of the slide sleeve can have a mounting for a toilet seat. Such a mounting can be an element independent of the slide sleeve. For example, it can be permanently or removablely connected to the slide sleeve.

[0042] A through-hole can be fitted with a cover, for example, if no wall mounting is present or planned in the through-hole for the sanitary ware. A cover is preferably placed in an opening of the through-hole, for example, in a mounting point that would be intended for a toilet seat.

[0043] In preferred embodiments of the sanitary article, two through-holes are spaced apart from each other in the surface of a rear region of the sanitary article. The sanitary article can then be attached to a wall via these two through-holes using two wall fixings according to the present invention.

[0044] The invention is described in more detail with reference to the examples shown in the following drawings. These show: Figure 1 shows a longitudinal cross-section through a toilet bowl with wall mounting according to the invention; Figure 2 shows a cross-section through the toilet bowl according to the invention. Fig. 1in the area of ​​wall mounting; Figure 3 a section of a side sectional view of a mounted sanitary ware; Figures 4 to 9 an assembly process of a wall-hung sanitary ware; Figure 10 a perspective partial view of a wall mounting; Figure 11 a perspective view of a slide valve; Figure 12 an oblique view of a front part of a wall bracket; Figure 13 a bottom view of a wall mounting, for example according to Fig. 10 .

[0045] If reference symbols are indicated in a figure for the purpose of graphical clarity, but are not mentioned in the immediately corresponding descriptive section, reference is made to their explanation in preceding or subsequent descriptive sections. Conversely, to avoid graphical clutter, certain reference symbols are not included in all figures for immediate understanding. In these cases, reference is made to the remaining figures. Position and direction indications such as vertical, horizontal, top, bottom, front, back, side, etc., refer to the normal mounting position of a sanitary fitting on a vertical wall.

[0046] Figure 1Figure 1 shows a longitudinal cross-section through a sanitary article 1 in the form of a toilet with a wall mounting 2. The toilet rests on a support surface 200 of the wall bracket 20. A sliding sleeve 3 is in a through-hole 10, which through-hole 10 extends vertically downwards through the toilet surface and through a rear part of the toilet.

[0047] Figure 2 shows a cross-section of the toilet Fig. 1The toilet has two through-holes 10 arranged laterally offset from a central plane. Preferably, a sliding sleeve 3 of a separate wall mounting 2 is inserted into each of the through-holes 10 for symmetrical mounting of the toilet to a wall. The rear of the toilet has corresponding recesses 11 for receiving the wall brackets 20. The recesses 11 are provided in a rear area on a right and on a left side of the toilet. The cross-section of a wall bracket 20 is essentially rectangular, which provides good handling of the wall bracket 20 with a flat contact surface 200.

[0048] Figure 3 shows a section of the rear area of ​​a sanitary article 1, such as a toilet or a bidet, for example according to Figs. 1 and 2The sanitary article 1 is attached to a wall 4 by means of wall fixings 2, wherein preferably two of the wall fixings 2 shown are provided in lateral rear areas of the sanitary article 1 (only one in Fig. 3 (to be seen). The back side 13 of the sanitary article 1, when mounted and firmly screwed in place, is preferably flush against the wall 4.

[0049] The sanitary article 1 has a through-hole 10 through its surface. The through-hole 10 runs vertically, is open downwards and leads into a rear inner cavity 11 of the sanitary article 1. The wall bracket 20 of the wall mounting 2 is located in this cavity, and the sanitary article 1 rests on the support surface 200 of the wall bracket 200.

[0050] The wall bracket 20 is attached to the wall 4 at its wall-side end 26 via a fixing bolt 40. The fixing bolt 40 is firmly anchored in the wall 4. The fixing bolt 40 typically has an external thread and is screwed into an internal thread (not shown) of a screw connection 29 in the wall-side area of ​​the wall bracket 20.

[0051] The wall bracket 20 is elongated and has a passage 21 in its preferably flat support surface 200. The passage 21 is relatively wide in its upper region, forming a cut-out, and then continues with a narrower diameter through the sliding surface 22 and the wall bracket 20.

[0052] A sliding sleeve 3 is vertically displaceable in the through-hole 10 of the sanitary article 1. The sliding sleeve 3 is a hollow tube for receiving the fastening screw 5. The sliding sleeve 3 extends through the through-hole 10 and engages with its lower end 30 in the recess.

[0053] The lower end 30 of the slide sleeve 3 is chamfered and runs on and along the slide surface 22. The slide surface 22 and the lower chamfered end 30 of the slide sleeve 3 are inclined downwards by approximately 40 to 50 degrees towards the wall 4.

[0054] The wall bracket 20 has a substantially prism-shaped portion 29 at its free end 27. The base of the prism is horizontally oriented, and the apex of the prism forms the upper crest of the prism-shaped portion 29. The sliding surface 22 forms the wall-side portion of the prism-shaped portion 29. The portion of the prism-shaped portion 29 facing the free end 27 of the wall bracket 20 is formed by the positioning surface 25. The positioning surface 25 starts at the free end 27 of the wall bracket 20 and slopes upwards towards the wall 4. The positioning surface 25 has an exemplary inclination angle of approximately 40 to 60 degrees from the horizontal.

[0055] The free end 27 of the wall bracket 20 is formed by a corner of the prism-shaped part 29.

[0056] In the Fig. 3In the example shown, the upper end of the prism-shaped part 29 forms an offset 24, in which a vertical surface section 23 is inserted on the wall side, adjoining the tip of the prism-shaped part 29. Following this vertical surface section 23 is the inclined sliding surface 22. In other words, the sliding surface 22 transitions at its upper end into a vertically arranged wall section. This forms a stop for the sliding sleeve 3 when it is moved away from the wall 4 in the opposite direction to the installation direction of the sanitary fitting 1.

[0057] The slider 6 is arranged below the prism-shaped part 29 of the wall bracket 20. The slider 6 is horizontally displaceable within the wall bracket 20. The slider 6 can be fixed or removable within the wall bracket 20.

[0058] A locking nut 52 is fixedly installed in the slide 6, which is in the form of a plate. The locking nut 52 can be inserted into a corresponding recess or be permanently installed.

[0059] The fastening screw 5 is inserted into the slide sleeve 3 such that it passes through the bottom of the slide sleeve 3, through the slide surface 22 and the prismatic part 29, and engages with the locking nut 52, where it is screwed in place. Preferably, one end of the screw 51 can exit downwards through the locking nut 52 and the slide 6.

[0060] The slide sleeve 3 has a radially inwardly directed shoulder 32 extending around its inner diameter, against which the screw head 50 of the fastening screw 5 abuts. It is thus secured against falling downwards out of the slide sleeve 3.

[0061] The slide sleeve 3 also has a longitudinally arranged recess 35 on one side, which serves as an anti-rotation device. The through-hole 10 in the sanitary article 1 accordingly has a shoulder 15 arranged on one side in front of the lower end of the through-hole 10. The upper end of the recess 35 and the shoulder 15 form an anti-rotation device. This allows the slide sleeve 3 to be inserted into the through-hole 10 from above and aligned such that the chamfered lower end 30 of the slide sleeve 3 rests flush against the slide surface 22 of the wall bracket 20.

[0062] The anti-rotation device is located in the Fig. 3 In the illustrated embodiment, it is arranged on the wall side. However, it can be provided on any radial side of the slide sleeve 3, for example on a front side, i.e., in the mounted state on a side of the slide sleeve 3 facing away from the wall 4.

[0063] In the Fig. 3In the illustrated embodiment of the wall mounting 2, the sliding sleeve 3 has a fastening means 33 in the form of an internal thread 33 at its upper end. A seat mounting 34 with a corresponding external thread is screwed into the upper end of the sliding sleeve 3. The seat mounting 34 serves to receive a seat or a toilet ring, or a cover (not shown) for the inlet opening 12 of the through-hole 10. By means of a separate seat mounting 34, which can be fastened in the sliding sleeve 3, a seat mounting 34 can be screwed in independently of the fastening of the sanitary article 1.

[0064] A cover serves as the upper closure of the through-hole 10 and may be provided for cleaning or visual reasons if a toilet seat is not present.

[0065] In the Figures 4 to 9 isA mounting process of a wall-hung sanitary article 1, for example a toilet, on a wall 4 using the wall mounting 2 according to the invention is described.

[0066] Two wall brackets 20 are pre-installed on wall 4 (only one is shown).

[0067] A sanitary article 1 is fitted with two slide sleeves 3. Due to the anti-rotation device 15, 35, the beveled lower end 30 of the slide sleeves 3 is already positioned with the bevel facing away from the wall 4.

[0068] Then the sanitary item 1 is pushed onto the wall brackets 20 in the direction of the arrow ( Fig. 4 ).

[0069] The lower end 30 of the slide sleeve 3 now contacts the positioning surface 25, which is located at the free end 27 of the wall bracket 20. As shown in Fig. 5 As can be seen, the slide sleeve 3 slides upwards along the positioning surface 25, which is again indicated by arrows.

[0070] After the sliding sleeve 3 has passed the uppermost point, i.e., the uppermost end of the positioning surface 25, it falls downwards onto the sliding surface 30 and into the engagement of the wall bracket 20 due to the offset 24. This loosely secures the sanitary fitting 1 to the wall bracket 20, and it no longer needs to be held in place. Fig. 6 The upward protrusion of the slide sleeve 3 from the through-hole 10 and, in particular, the falling of the slide sleeve 3 is clearly visible from the outside and clearly indicates that the sanitary article 1 is now in a secure pre-assembly position.

[0071] Then the fastening is carried out using fastening screw 5, for example with an internal hexagon, as in Figs. 7 and 8 shown.

[0072] The fastening screw 5 is inserted from above into and through the slide sleeve 3 and screwed to the slide 6 with recessed locking nut 52. This allows work to be carried out from above, which facilitates convenient assembly.

[0073] The screwing action ensures that the slide sleeve 3 is pressed diagonally downwards along the slide surface 30 while simultaneously the slide 6 is pulled towards the wall 4. This continues until the locking position is reached, which generally corresponds to the sanitary fitting 1 being fully against the wall 4.

[0074] In Fig. 9 A seat fixing 34 is inserted from above into the slide sleeve 3 (direction of arrow), preferably screwed in, as preparation for the subsequent installation of a toilet seat.

[0075] In Fig. 10A partial perspective view through a wall mounting 2 is shown. The essentially cuboid wall bracket 20 has a straight wall-side end 26 and a chamfered front end 27. The chamfered front end 27 is formed by the positioning surface 25. The front area of ​​the wall bracket 20 in the region of the positioning surface 25 is ribbed, which contributes to the stability of the wall bracket 20. In the Fig. 10 In the embodiment shown, several narrow ribs 28 are provided.

[0076] The support surface 200 of the wall bracket 20 has a passage 21 for receiving the sliding sleeve 3. The passage 21 has a square cross-section, at least in its upper region. The cylindrical sliding sleeve 3, inserted into the passage 21, has a recess 35 in its lower half as part of an anti-rotation device. Fig. 10 The anti-rotation device is arranged facing forwards towards the positioning surface 25.

[0077] The transparent illustration of the slide sleeve 3 shows the fastening screw 5, which has a screw head 50 operable with an Allen key, and the stop 32 for the fastening screw 5. Also shown are fastening means 33 at the upper end of the slide sleeve 3 and an associated seat attachment 34. The fastening means 33 of the slide sleeve 3 and the seat attachment 34 are designed as snap fasteners, with projections extending around the circumference of the seat attachment 34 engaging in corresponding recesses along the inner circumference of the slide sleeve 3.

[0078] The slider 6 is incorporated into the underside of the wall bracket 20.

[0079] Fig. 11 shows a slider 6 in the form of a plate, which fits into a wall bracket 20, as for example in Fig. 12As shown, it can be inserted and fixed in place. For this purpose, the slider 6 has projections 61 extending laterally along its length. These projections interact with lateral, also longitudinally extending rails 62 in a recess 65 of the wall bracket 2. The slider 6 also has two stops 610 extending radially outwards to the sides.

[0080] The slider 6 is inserted into the recess 65 of the wall bracket 20 and pushed along the rails 62 into the wall bracket 20. The slider 6 can be pushed into the wall bracket 20 until the stops 610 abut the front of the rails 62. The rails 62 simultaneously secure the slider 6 against falling out of the wall bracket 20.

[0081] The slide 6 also features a locking element 64, which holds the slide 6 in a pre-assembled position in the wall bracket 20. Typically, the slide 6 is inserted into the wall bracket 20 until the locking element 64 locks the slide 6 in the wall bracket 20. The locking element 64 is designed as a bulge on the top surface of the slide 6, which can serve as a frictional and positive locking mechanism.

[0082] The slide 6 has a nut 52 that is fixedly mounted within the slide 6 to prevent rotation. The nut 52 is located in the plane of the slide 6. In the mounted position of the slide 6, the nut 52 is aligned with the passage 21 in the wall bracket 20, such that a screw end 51 of a fastening screw 5 can be screwed into the nut 52.

[0083] The wall bracket 20 according to Fig. 12 It also features ribbing in the area of ​​positioning surface 25. These are located in the Fig. 12In the embodiment shown, few ribs are provided, and only one wider central rib 28 is provided.

[0084] Fig. 13 shows a bottom view of a wall mounting 2, for example according to Fig. 10 , in which the slider 6 is in its end position. The end position corresponds to a mounted and securely screwed sanitary fitting 1, for example a toilet. The locking nut 52 and the screw end 51 of the fastening screw 5 inserted into the locking nut 52 are clearly visible.

[0085] Also shown are the inner, laterally mounted rails 62 of the wall bracket 20, which extend from the front, the free end 27 of the wall bracket 20, to approximately two-thirds of its length. The rails 62 terminate in a stop 63 running horizontally and perpendicular to the rails 62, which also serves as a stop for a slider 6 that can be inserted into the wall bracket 20.

[0086] The wall bracket has a locking element 64 which holds the slider 6 in a pre-assembled position in the wall bracket 20 and simultaneously ensures the alignment of the fastening screw 5 and nut 52. During assembly, a secure connection is created by the screw connection. The slider 6 is pulled along the rails 62 in the wall bracket 20 towards the stop 63. This releases the now unnecessary locking mechanism of the slider 6 by means of the two locking elements 64. The locking element 64 is designed here as a recess in the wall bracket 20, which recess is fitted with a locking element 64, for example in the form of a bulge, as shown in Fig. 11 shown, interacts.
