Wall mount
Technical Field
The present invention relates to a wall mount according to the preamble of claim 1.
Background
A wall mount for a sanitary article is known from EP 3 428 353. The wall mount comprises an anchor element for fastening to a wall, a threaded rod and a threaded element connectable to the mounting frame. The threaded element can be brought into an engaged position and a released position. In the release position, the threaded rod is free to move axially, and in the engaged position, the threaded element is engaged with the threaded rod such that the threaded rod can be adjusted by a threaded movement.
EP 3441 536 discloses another wall mount having an insert member with a threaded portion. The insertion part is pivotable here and can be moved from a coarse adjustment position into a fine adjustment position. Drawbacks of EP 3441 536 include the mounting of the insert part and its accommodation on the fixing part. In particular, the installation in the factory is very complex and is not easy for the plumber to operate.
Publications EP 3 404 151 and EP 3 404 153 disclose fastening kits which are also capable of coarse and fine adjustment between the fastening element and the threaded rod.
A disadvantage of the wall mounts known from the prior art is that they have to be provided with different components for different mounting situations. For example threaded rods of different lengths.
Disclosure of Invention
Starting from this prior art, the object of the present invention is to provide a wall mount which overcomes the disadvantages of the prior art. In particular, a wall mount should be provided which is more flexible to accommodate different mounting situations.
The wall mount according to claim 1 achieves this object. Correspondingly, the wall mount comprises
An anchor element having a fastening portion for fastening the anchor element to the support structure and an anchor element side bearing portion adjoining the fastening portion and extending along the central axis,
at least one intermediate element having a first support and a second support, and
a fastening element having a fastening element side support and a fastening portion for fastening a sanitary element.
The intermediate element is displaceably and fixedly connected with its first bearing to the anchor element side bearing. Furthermore, the fastening element is displaceably and fixedly connected with its fastening element side support to the second support. The support portions are respectively formed such that the corresponding support portions are respectively telescopically engaged with each other.
Due to this telescopic engagement, the wall mount has the following advantages: the length from the fastening portion of the anchoring element to the fastening portion of the fastening element can be adjusted over a large adjustment range or length range, which enables the wall mount to be adapted to a number of different mounting situations.
The expression "the respective bearing parts are telescopically engaged with each other" is to be understood as
The first support of the intermediate element is telescopically connected to the anchor element side support, and
the first bearing of the intermediate element is telescopically connected to the fastening element side bearing.
The expression "displaceable and fixedly connectable" is understood to mean that the parts can be displaced relative to each other and can be fixed after the displacement has been completed, so that no further displacement is possible. This can be achieved, for example, with a threaded connection in which the individual elements are displaced relative to one another by rotation, and in which the fixation is achieved due to the self-locking effect of the threads without rotational movement. Other connectors are also conceivable.
The fastening element side support is part of the fastening element and the anchor element side support is part of the anchor element.
In a first variant, the anchor-element-side bearing is formed as a bearing opening, and the first bearing projects into the bearing opening and is displaceably and fixedly mounted in the bearing opening. Further, the second support portion is formed as a support opening, and the fastening element side support portion is displaceably and fixedly mounted in the support opening.
In a second variant, the first bearing is formed as a bearing opening, and the anchor element-side bearing projects into the bearing opening and is displaceably and fixedly mounted in the bearing opening. Further, the fastening element side support portion is formed as a support opening, and the second support portion is movably and fixedly installed in the support opening.
The bearing opening preferably has a cylindrical cross section and extends in the direction of the central axis. The support part projecting into the support opening likewise has a cylindrical cross section and extends along the central axis. The central axes of the sections extend co-linearly with each other.
Preferably, the first support portion has a first threaded portion, and the anchor element side support portion has an anchor element side threaded portion, wherein the two threaded portions are engaged with each other.
Preferably, the second support portion has a second threaded portion, and the fastening element side support portion has a fastening element side threaded portion, wherein the two threaded portions are engaged with each other.
In one modification, preferably, the first threaded portion is an external thread, and the anchor member side threaded portion is an internal thread. The second thread portion is an internal thread, and the fastening element side thread portion is an external thread.
In another modification, preferably, the first threaded portion is an internal thread, and the anchor member side threaded portion is an external thread. The second thread portion is an external thread, and the fastening element side thread portion is an internal thread.
The internal thread engages into the external thread.
Preferably, the pitch of the first thread portion and the anchoring element side thread portion is greater than or less than or equal to the pitch of the second thread portion and the fastening element side thread portion.
By varying the pitch, a greater flexibility of the wall mount configuration for different applications is achieved.
Preferably, one of the two mutually engaging bearing parts has an adjusting element which can be moved from a coarse adjusting position to a fine adjusting position. The adjusting element may be arranged between the intermediate element and the anchoring element and/or between the intermediate element and the fastening element.
In the case of an adjusting element arranged between the intermediate element and the anchoring element, the adjusting element is positioned in the coarse adjusting position such that the intermediate element can be moved freely relative to the anchoring element for coarse adjustment. In the fine adjustment position, the adjustment element is positioned such that the intermediate element is movable relative to the anchor element for fine adjustment.
In the case of an adjusting element arranged between the intermediate element and the fastening element, the adjusting element is positioned in the coarse adjusting position such that the intermediate element can be moved freely relative to the fastening element for coarse adjustment. In the fine adjustment position, the adjustment element is positioned such that the intermediate element can be moved relative to the fastening element for fine adjustment.
In the coarse adjustment position, a movement is allowed with which a large difference in length can be achieved in a short time. In the fine adjustment position, movement is allowed, which allows for a smaller length difference.
Preferably, the adjusting element has one of said threaded portions, wherein in the coarse adjusting position the threaded portion is not engaged with the other threaded portion, and wherein in the fine adjusting position this threaded portion is engaged with the other threaded portion.
Preferably, the adjustment element provides a threaded portion in the form of an internal thread.
In the coarse adjustment position, the adjustment elements are thus positioned such that the threaded portions do not engage each other, so that the corresponding elements can be displaced freely in the direction of the central axis. In the fine adjustment position, the screw portions are engaged such that one of the elements is subjected to thrust in the central axis direction by rotation of the element.
Preferably, the wall bracket further has at least one lock nut provided with at least one of said external threads.
Preferably, the maximum displacement length between the intermediate element and the anchoring element is smaller than the maximum displacement length between the intermediate element and the fastening element. Alternatively, the maximum displacement length between the intermediate element and the anchoring element is greater than the maximum displacement length between the intermediate element and the fastening element. Alternatively, the maximum displacement length between the intermediate element and the anchoring element is equal to the maximum displacement length between the intermediate element and the fastening element.
By varying the displacement length between the individual elements, a greater flexibility of the wall bracket configuration for different applications is achieved.
Preferably, the maximum displacement length between the fastening portion of the anchoring element and the fastening portion of the fastening element is 100 to 300 mm.
A device comprising at least one wall bracket according to the above description and a sanitary product having a support opening into which a fastening element engages.

Detailed Description
In fig. 1 to 6, a wall mount 1 according to an embodiment of the invention is shown. Fig. 7 shows a detail of the wall mount according to fig. 1 to 6, and a sanitary product 23, here in the form of a mounting profile of a mounting frame. Wall brackets are used to fasten sanitary products to a supporting structure, such as a wall of a building or a profile rail or other fixedly arranged element. The sanitary product 23 is, for example, a mounting frame on which further sanitary elements are arranged, such as a water tank, a toilet, a urinal, a sink, etc.
The wall mount 1 comprises an anchor element 2, an intermediate piece 5 connected to the anchor element 2, and a fastening element 8 connected to the intermediate piece 5. The anchoring element 2, the intermediate piece 5 and the fastening element 8 are in this case telescopically movable relative to each other. Due to this telescopic arrangement, a large adjustment range of the length L of the wall mount can be achieved with a small number of individual elements. The length L is specified by the desired distance between the sanitary product 23 and the building wall.
In fig. 1 and 2, the anchoring element 2, the intermediate piece 5 and the fastening element 8 are in an almost fully retracted position. Fig. 3 to 7 show different positions of the anchoring element 2, the intermediate piece 5 and the fastening element 8, wherein the length variation of the length L is evident.
The anchor element 2 is formed with a fastening portion 3 for fastening the anchor element 2 to a support structure and an anchor element side bearing portion 4 adjoining the fastening portion 3 and extending along a central axis M. The fastening portion 3 comprises in the shown embodiment a stop surface 17 with which the anchoring element 2 is placed on the support structure. The fastening portion 4 further comprises an opening 18 through which a screw (not shown in the figures) can be guided. The anchoring element 2 can then be fastened to the building wall with screws.
The intermediate element 5 has a first support 6 and a second support 7. The intermediate element 5 projects with a first bearing 6 into the anchor element-side bearing 4. The intermediate element 5 is displaceably and fixedly connected with the first bearing 6 to the anchor element-side bearing 4. The intermediate element 5 is correspondingly displaceable relative to the anchoring element 2 or its position can be adjusted relative to the anchoring element 2. After the displacement or adjustment has been completed, the intermediate element 5 can be fixed to the anchoring element 2. As described below, in the embodiment shown, the intermediate element 5 and the anchoring element 2 are connected to each other via a threaded connection. In this case, the intermediate element 5 and the anchoring element 2 are fixed relative to each other via the self-locking action of the threads.
In the embodiment shown, a single intermediate element is provided. In other embodiments, it is also conceivable to provide several intermediate elements which telescopically engage each other.
The fastening element 8 has a fastening element side support 9. The fastening element 8 also has a fastening portion 10 for fastening the sanitary element 23. In the embodiment shown, the fastening portion 10 is formed as a screw head 19. The screw head 19 engages in a bearing opening 24 on the sanitary element 23. The fastening element-side bearing 9 projects into the second bearing 7 of the intermediate element 6. Here, the second support 7 is displaceably and fixedly connected to the fastening element-side support 9. For displaceability and fixability, reference is made to the description of the connection between the first support 6 and the anchor element-side support 4.
The length L of the wall anchor 1 is defined as the distance from the stop surface 17 of the anchor element as seen in the direction of the central axis M up to the screw head 19 of the fastening element 8. The maximum displacement length of the length L is preferably 100 to 300 mm. This means that the length L can be adjusted between 100 mm and 300 mm.
It is obvious that the support parts 4, 6, 7, 9 are formed such that the corresponding support parts 4, 6, 7, 9 are telescopically engaged with each other, respectively. In the embodiment shown, the anchor element-side bearing 4 is formed as a bearing opening 25, and the first bearing 6 projects into said bearing opening 25. The first bearing 6 is mounted displaceably and fixedly in a bearing opening of the anchor element-side bearing. The second support 7 is formed as a support opening 26, and the fastening element side support 9 is displaceably and fixedly mounted in the support opening 26.
In the illustrated embodiment, the first support portion 6 is formed with a first threaded portion 11, and the anchor-element-side support portion 4 is formed with an anchor-element-side threaded portion 12. The two threaded portions 11, 12 are engaged with each other. The second support portion 7 is also formed with a second screw portion 13, and the fastening element side support portion 9 is formed with a fastening element side screw portion 14. The two threaded portions 13, 14 are engaged with each other.
In the illustrated embodiment, the anchor member-side screw portion 12 is formed as an internal screw thread, and the first screw portion 11 is formed as an external screw thread. Further, the second screw portion 13 is formed as a female screw, and the fastening element side screw portion 14 is formed as a male screw.
In the embodiment shown, the first threaded portion 11 and the anchor element-side threaded portion 12 are integrally formed on the intermediate element 5 or on the anchor element 2. An optional lock nut 16 is screwed onto the first threaded portion 12 and serves to mechanically firmly fix the two threaded portions 11, 12 relative to each other in case of adjusting the desired relative position between the intermediate element 5 and the anchoring element 2.
In the embodiment shown, the second threaded portion 13 is part of an adjusting element 15. The adjusting element 15 can be moved from a coarse adjusting position to a fine adjusting position. In the figures, the adjusting elements 15 are each in a fine adjustment position. In the coarse adjustment position, the adjustment elements 15 are each positioned such that the intermediate element 5 is freely movable relative to the fastening element 8 for coarse adjustment. No engagement occurs between the second screw portion 13 and the fastening element side screw portion 14. A corresponding coarse adjustment can be achieved in this case. In the fine adjustment position, the adjustment element 15 is placed such that an engagement takes place between the fastening element side threaded portion 14 and the second threaded portion 13. This means that micro-feeding between the intermediate element 5 and the fastening element 8 is achieved with rotation of the fastening element 8.
In other embodiments, it is also conceivable that the threaded connection between the anchoring element 2 and the intermediate element 5 is likewise provided with an adjusting element 15; or the adjusting element 15 may be omitted entirely.
In the exemplary embodiment shown, the adjusting element 15 is mounted in a receptacle 20 in the front region of the intermediate element 5. The adjusting element 15 has two legs 21 which are connected on the end side to a connecting leg 22. Correspondingly, the adjusting element 15 can be actuated via the connecting leg 22. The second screw portion 13 is formed on the inner side of the leg 21. As shown, the leg 21 protrudes into a bearing opening 26 in the intermediate element 5. The adjusting element 15 can be moved transversely to the central axis from a coarse adjusting position to a fine adjusting position and can be returned again.
Fig. 7 shows a device comprising at least one wall mount 1 according to fig. 1 to 6 and a sanitary product 23 with at least one support opening 24 into which a fastening element 8 engages. The position of the sanitary product 23 at a distance from the support structure to which the anchoring element 2 is fastened can be adjusted by means of the length adjustment of the wall bracket 1.
