Description

TECHNICAL FIELD

The present invention relates to a wall mount as claimed in the preamble of claim 1.

PRIOR ART

A wall mount for a sanitary article has become known from EP 3 428 353. The wall mount comprises an anchor element for fastening to a wall, a threaded rod and a thread element which can be connected to a mounting frame. A thread element can be brought into an engagement position and a release position. In the release position, the threaded rod can be axially freely moved and in the engagement position the thread element is engagement with the threaded rod so that the threaded rod can be adjusted via a screw movement.
EP 3 441 536 discloses a further wall mount which has an insertion part with a thread portion. The insertion part is pivotable here and can be brought from a rough adjustment position into a fine adjustment position. Disadvantages of EP 3 441 536 include the mounting of the insertion part and its receiving on the securing part. In particular, mounting in the factory is very complex and handling is also not very easy for the plumber.
The publications EP 3 404 151 and EP 3 404 153 disclose fastening sets which also enable rough adjustment and fine adjustment between a fastening element and a threaded rod.
The wall mounts known from the prior art have the disadvantage that they must be provided with different parts for different installation situations. For example, with threaded rods of different lengths.

SUMMARY OF THE INVENTION

Starting from this prior art, one object on which the invention is based is to indicate a wall mount which overcomes the disadvantages of the prior art. In particular, a wall mount should be indicated which can be adapted more flexibly to different installation situations.
A wall mount as claimed in claim 1 achieves this object. Accordingly the wall mount comprises

- an anchor element with a fastening portion for fastening the anchor element to a supporting structure and with an anchor element-side bearing portion which adjoins the fastening portion and extends along a central axis,
- at least one intermediate element with a first bearing portion and a second bearing portion, and
- a fastening element with a fastening element-side bearing portion and with a fastening portion for fastening a sanitary element.

The intermediate element is displaceably and fixably connected with its first bearing portion to the anchor element-side bearing portion. The fastening element is furthermore displaceably and fixably connected with its fastening element-side bearing portion to the second bearing portion. Said bearing portions are formed in each case in such a manner that the corresponding bearing portions engage in each case telescopically in one another.
As a result of the telescopic engagement, this wall mount has the advantage that the length from the fastening portion of the anchor element to the fastening portion of the fastening element can be adjusted over a large adjustment range or length range, which enables an adaptation of the wall mount to many different installation situations.
The expression “that the corresponding bearing portions engage in each case telescopically in one another” should be understood such that

- the first bearing portion of the intermediate element is connected telescopically to the anchor element-side bearing portion, and
- the first bearing portion of the intermediate element is connected telescopically to the fastening element-side bearing portion.

The expression “movably and fixably connected” should be understood such that said portions are displaceable relative to one another and are fixable after completed displacement so that a further displacement is no longer possible. This can be achieved, for example, with a thread connection in the case of which the individual elements are displaced relative to one another by rotation and in the case of which said fixing is achieved as a result of the self-locking effect of the thread in the absence of the rotational movement. Other connections are also conceivable.
The fastening element-side bearing portion is part of the fastening element and the anchor element-side bearing portion is part of the anchor element.
In a first variant, the anchor element-side bearing portion is formed as a bearing opening and the first bearing portion protrudes into said bearing opening and is movably and fixably mounted in the bearing opening. The second bearing portion is furthermore formed as a bearing opening and the fastening element-side bearing portion is movably and fixably mounted in the bearing opening.
In a second variant, the first bearing portion is formed as a bearing opening and the anchor element-side bearing portion protrudes into said bearing opening and is movably and fixably mounted in the bearing opening. The fastening element-side bearing portion is furthermore formed as a bearing opening and the second bearing portion is movably and fixably mounted in the bearing opening.
