TECHNICAL AREA

The present invention relates to a wall mount according to the preamble of claim 1.

STATE OF THE ART

From the EP3 428 353 A wall bracket for a sanitary article has become known. The wall bracket comprises an anchor element for fastening to a wall, a threaded rod and a threaded element which can be connected to a mounting frame. A threaded element can be brought into an engagement position and a release position. In the release position, the threaded rod can be moved freely axially and in the engagement position, the threaded element is in engagement with the threaded rod so that the threaded rod can be adjusted via a screwing movement.

The EP3 441 536 discloses another wall mount which has an insert with a threaded section. The insert is pivotable and can be moved from a coarse adjustment position to a fine adjustment position. A disadvantage of the EP3 441 536 is the storage of the insert part and its attachment to the safety part. In particular, the factory assembly is very complex and handling is not easy for the plumber either.

The printed publications EP3 404 151 and EP3 404 153 reveal fastening sets, which also allow a coarse adjustment and a fine adjustment between a fastening element and a threaded rod.

DESCRIPTION OF THE INVENTION

Based on this state of the art, the invention is based on the object of The aim is to provide a wall mount that overcomes the disadvantages of the prior art. In particular, the aim is to provide a wall mount that is easier to handle.

• ein Ankerelement mit einem Befestigungsabschnitt zur Befestigung des Ankerelements an einem Gebäude und mit einem sich dem Befestigungsabschnitt anschliessenden sowie sich entlang einer Mittelachse erstreckenden Aufnahmeabschnitt mit einem sich entlang der Mittelachse erstreckenden Aufnahmeraum,
• eine im Aufnahmeraum bewegbar gelagerte Gewindestange mit einem Aussengewinde,
• ein Klemmelement mit einem Lagerabschnitt, mit welchem das Klemmelement an einer Lagerstelle am Aufnahmeabschnitt gelagert ist, und mit einer vom Lagerabschnitt abstehende Klemmlasche, welche von einer Grobeinstelllage in eine Feineinstelllage bewegbar ist,
• ein im Aufnahmeraum und/oder an der Klemmlasche angeordneter Innengewindeabschnitt, und
• ein von einer Ausgangslage in eine Endlage verschiebbares Betätigungselement zur Bewegung der Klemmlasche von der Grobeinstelllage in die Feineinstelllage.

This object is achieved by the object according to claim 1. Accordingly, a wall mount comprises

• an anchor element with a fastening section for fastening the anchor element to a building and with a receiving section adjoining the fastening section and extending along a central axis with a receiving space extending along the central axis,
• a threaded rod with an external thread that is movably mounted in the receiving space,
• a clamping element with a bearing section, with which the clamping element is mounted at a bearing point on the receiving section, and with a clamping tab protruding from the bearing section, which can be moved from a coarse adjustment position to a fine adjustment position,
• an internal thread section arranged in the receiving space and/or on the clamping lug, and
• an actuating element that can be moved from an initial position to an end position for moving the clamping tab from the coarse adjustment position to the fine adjustment position.

In the coarse adjustment position, the clamping tab is positioned in such a way that the external thread of the threaded rod is not in engagement with the internal thread section, so that the threaded rod can be moved in the receiving space in the direction of the central axis. In the fine adjustment position, the clamping tab is positioned in such a way that the external thread of the threaded rod is in engagement with the internal thread section, so that by turning the threaded rod, the threaded rod is fed in the direction of the central axis.

The arrangement of the clamping element with the bearing section and the clamping tab has the advantage that a wall bracket can be provided on which the element to be moved from the coarse adjustment position to the fine adjustment position is simply and yet securely mounted on the anchor element.

The coarse adjustment position allows a coarse adjustment of the threaded rod, whereby the threaded rod can be moved with a longitudinal movement in the direction of the central axis. The installer can then adjust the threaded rod to the centimeter, for example. Pre-assemble precisely. In the fine adjustment position, the installer can then position the threaded rod with millimeter precision.

In the initial position, the actuating element is positioned so that the clamping tab is in the coarse adjustment position. In the end position, the actuating element is positioned so that the clamping tab is in the fine adjustment position.

The clamping tab and the bearing section are connected to one another in one piece. The clamping tab is thus firmly connected to the anchor element via the bearing section. The bearing section is preferably mechanically firmly connected to the anchor element. Particularly preferably, only the clamping tab is moved.

The clamping tab is preferably parallel to the central axis and radially spaced from the central axis. When moving from the coarse adjustment position to the fine adjustment position, the clamping tab is moved towards the central axis. This is a pivoting movement around the connection point between the clamping tab and the bearing section.

The term "tab" in connection with the clamping tab refers to a body which extends along an axis and has a length which is greater than the width.

Preferably, the clamping tab is designed as a spring-elastic tab. The spring-elastic design is such that the clamping tab is automatically moved back into the coarse adjustment position as soon as the clamping tab is no longer held in the fine adjustment position by the actuating element.

The spring-elastic design has the advantage that the clamping tab is always in the coarse adjustment position or that the clamping tab moves back from the fine adjustment position to the coarse adjustment position when the actuating element is in the first position.

The term "spring-elastic" means that the clamping tab automatically returns to the coarse adjustment position after the force pressing the clamping tab into the fine adjustment position is removed.

Alternatively, the clamping tab is designed as a plastically deformable tab, such that that the clamping tab is no longer moved back to the coarse adjustment position after the fine adjustment position has been reached.

Preferably, the clamping tab is designed as a free end opposite the point at which the clamping tab is formed on the bearing section. This means that the clamping tab is designed as a free arm which extends away from the bearing section.

In other words, the clamping tab extends away from the bearing section as a spring-elastic tab. A type of bending beam is created which is only clamped at one end, namely at the point where it joins the bearing section.

Preferably, the clamping tab is pivoted relative to the fixed bearing section when moving from the coarse adjustment position to the fine adjustment position. This means that the bearing section remains in its fixed position and the clamping tab is moved.

Preferably, the clamping element has a wall region with a groove, wherein the wall region extends away from the bearing section in the direction of the central axis and wherein the clamping tab lies in the groove.

The advantage of the wall area and the fact that the clamping tabs are located in the groove of the wall area is that the clamping tab can be protected from mechanical influences that could lead to damage.

Preferably, the actuating element is mounted on the clamping element so that it can move from the starting position to the end position. The movement of the actuating element is preferably a movement in the direction of the central axis.

Preferably, the actuating element has an opening with an inner wall. The clamping tab has a wedge-shaped stop surface, wherein when the actuating element moves from the starting position to the end position, the wedge-shaped stop surface comes into contact with the inner wall and is moved from the coarse adjustment position to the fine adjustment position.

The wedge-shaped stop surface is designed in such a way that the clamping tab is moved closer to the fine adjustment position as the actuating element is pushed forward, starting from the starting position.

Furthermore, the actuating element is held in its end position by at least one locking tab protruding from the clamping element. This prevents the actuating element from moving back to its starting position, while at the same time the clamping tab remains in the fine adjustment position.

Preferably, in the end position, the actuating element rests against a stop surface protruding from the clamping element.

The clamping element preferably has at least one locking element with which the clamping element locks into place at the bearing point. The bearing point preferably has a correspondingly designed locking opening.

Preferably, the bearing section is provided by a cylindrical opening on the clamping element. The bearing point has a cylindrical bearing surface extending around the central axis, the bearing surface coming into contact with the inner wall of the opening. In other words, the bearing section completely surrounds the bearing surface. That is, the bearing section extends around the bearing surface. Preferably, the bearing surface has a bevel, the clamping tab lying above the bevel. When moving from the coarse adjustment position to the fine adjustment position, the clamping tab is moved towards the bevel. The bevel creates space for the clamping tab.

Preferably, the receiving space is delimited by a side wall, wherein the clamping tab can be moved into the receiving space through a cutout in the side wall.

Preferably, the internal thread section is arranged both on the clamping tab and in the receiving space. There are therefore two internal thread sections into which the threaded rod engages when the clamping tab is in the fine adjustment position.

A method for mounting a wall bracket as described above is specified in that the actuating element is brought into the starting position so that the clamping bracket is brought into the coarse adjustment position such that the threaded rod is in the

Receiving space is movable in the direction of the central axis; and
that after the coarse adjustment has been made, the actuating element is brought into the end position so that the clamping tab is brought into the fine adjustment position in such a way that by turning the threaded rod, the threaded rod is fed in the direction of the central axis.

Further embodiments are specified in the dependent claims.

The anchor element 2 comprises a fastening section 3 for fastening the anchor element 2 to a building. The anchor element 2 also comprises a receiving section 4 which adjoins the fastening section 3 and extends along a central axis M and has a receiving space 5 which extends along the central axis M. In the embodiment shown, the anchor element 2 comprises a fastening opening 26 through which a screw for fastening an anchor element 3 to the building can be passed. The fastening section 3 is also designed to contain plates and has corresponding bearing structures 27 protruding from the plate.

The threaded rod 6 is movable in the receiving space 3 and has an external thread 7. In the embodiment shown, the threaded rod 6 also has a head section 28 which comprises a screw head 29. The screw head 29 has actuating structures in the form of slots and an external hexagon.

The clamping element 8 is mounted with a bearing section 9 at a bearing point 10 on the receiving section 4. The bearing point 10 is located on the outside of the receiving section 4. The clamping element 8 also comprises a clamping tab 11 protruding from the bearing section 10. The clamping tab 11 can be moved from a coarse adjustment position G to a fine adjustment position F, which is explained in more detail below. In the embodiment shown, an internal thread section 12 is arranged in the receiving space 5 and on the clamping tab 5. When the clamping tab 11 is in the fine adjustment position F, the external thread 7 of the threaded rod 6 engages in the internal thread section 12 and the threaded rod 6 can be fed forward via a rotary movement.

The actuating element 12 is arranged to be displaceable from a starting position to an end position and serves to move the clamping tab 11 from the coarse adjustment position G to the fine adjustment position F.

The clamping tab 11 is designed as a spring-elastic tab. The design of the clamping tab 11 is such that the clamping tab 11 is automatically moved back into the coarse adjustment position G as soon as the clamping tab 11 is no longer held in the fine adjustment position F by the actuating element 13. The clamping tab 11 is designed as a free, spring-loaded arm which protrudes accordingly from the bearing section 9.

Opposite the point at which the clamping tab 11 is formed on the bearing section 9, the clamping tab 11 therefore has a free end.

The clamping tab 11 can be pivoted relative to the fixed bearing section 9 of the clamping element 8 during the movement from the coarse adjustment position G to the fine adjustment position F. The clamping tab 11 is pivoted from the coarse adjustment position G to the threaded rod 6 to the fine adjustment position F.

In the embodiment shown, the clamping element 8 has an optional wall region 14. The wall region 14 has a groove 15 which interrupts the wall region 14 and in which the clamping tab 11 is arranged.
