Description

TECHNICAL AREA

[0001] The present invention relates to a wall bracket according to the preamble of claim 1. STATE OF THE ART

[0002] A wall bracket for a sanitary fitting is disclosed in EP 3 428 353. The wall bracket comprises an anchor element for attachment to a wall, a threaded rod, and a threaded element that can be connected to a mounting frame. The threaded element can be moved into an engagement position and a release position. In the release position, the threaded rod can move freely axially, and in the engagement position, the threaded element engages with the threaded rod, allowing the rod to be adjusted by a screwing motion.

[0003] EP 1 096 075 discloses another wall bracket, which has a joint that allows the screw to pivot towards a bearing element. Although very good mounting results were achieved with EP 1 096 075 for corner mounting, the application of the wall bracket is limited. In particular, it cannot compensate for unevenness on the wall surface. PRESENTATION OF THE INVENTION

[0004] Based on this prior art, the invention is based on the objective of providing a wall bracket that overcomes the disadvantages of the prior art. In particular, a preferred objective of the present invention is to provide a wall bracket for attachment to a supporting structure, such as a wall of a building, which is easier to adapt to the conditions specified by the supporting structure.

[0005] This problem is solved by the subject matter of claim 1. Accordingly, a wall bracket comprises an anchor element with a fastening section for attaching the anchor element to a supporting structure and with a bearing section on the anchor element side, as well as a fastening element extending along a central axis with a bearing section on the fastening element side and with a fastening section for attaching a sanitary fixture. The fastening element and the anchor element are connected to each other via their respective bearing sections. The bearing section on the fastening element side and the bearing section on the anchor element side are in mechanical engagement with each other. The anchor element has a rear surface and a front surface. The anchor element can be placed on or brought into contact with the supporting structure via its rear surface. The fastening element projects from its front surface.The bearing section on the anchor element side and the bearing section on the fastening element side form a ball joint with a ball socket and a ball head.

[0006] The ball joint design offers the advantage of greater flexibility in moving the fastening element relative to the anchor element, thus compensating for local unevenness in the supporting structure. For example, the anchor plate can be attached to the supporting structure across its entire surface, and the fastening element can then be aligned with the sanitary fixture via the ball joint. This eliminates the need for shims or similar materials between the supporting structure and the anchor element, thereby simplifying installation.

[0007] The ball joint, that is, the socket and the ball head, is arranged in such a way that, when the anchor element is fixed, a tensile force acting on the fastening element will not cause the ball joint to separate. In other words, the ball joint acts as a kind of stop against this tensile force.

[0008] The socket and the ball head are in planar contact with each other. The contact surface on the socket side has the shape of a spherical segment, and the contact surface on the ball head side also has the shape of a spherical segment. A spherical segment is understood to be a portion of a sphere. The two spherical contact surfaces share the same center point when the ball head is in the socket.

[0009] Preferably, the ball joint is designed such that movement between the anchor element and the fastening element is permitted in at least two or exactly two degrees of freedom, whereby when the two bearing sections are engaged, translational movement between the two bearing sections is prevented. This means that the fastening element is essentially pivotable about the ball joint for the purpose of alignment.

[0010] Preferably, the bearing section on the anchor element side is designed as a ball socket or as a segment of a ball socket, and the bearing section on the fastening element side is designed as a ball head or as a segment of a ball head.

[0011] Alternatively, the bearing section on the fastening element side is designed as a ball socket or as a segment of a ball socket, and the bearing section on the anchor element side is designed as a ball head or as a segment of a ball head.

[0012] The ball head is mounted in the ball socket so that it can pivot at an angle.

[0013] Preferably, the ball socket has an opening towards its rear surface, which is open towards the rear surface. The opening has a clear width larger than the maximum outer diameter of the ball head. Furthermore, the ball socket has an opening opposite the opening, through which the mounting section protrudes from the ball socket.

[0014] This allows the fastening element to be connected to the anchor element from the rear surface, with the ball head also being inserted into the ball socket from the rear surface. This allows for very simple installation.

[0015] In one embodiment, the ball joint is designed such that the central axis of the fastening element can be pivoted from a starting position in which the central axis of the fastening element is perpendicular to the rear surface of the anchor element by a pivot angle α of a maximum of 10°, in particular by a pivot angle α of a maximum of 8°, to the starting position.

[0016] In other words, the maximum swivel range is limited by a cone whose apex lies in the center of the ball joint and whose opening angle is a maximum of 20°, in particular a maximum of 16°.

[0017] Preferably, the movement of the fastening element is limited by a side edge of the ball socket and by a shaft area on the fastening element which abuts the side edge.

[0018] In another embodiment, the ball socket has a relief cut which is arranged such that, starting from the initial position in which the central axis is perpendicular to the rear surface, the fastening element can be pivoted by a swivel angle β of a maximum of 50°, in particular by a swivel angle β of a maximum of 45°.

[0019] This large swivel angle β allows the wall bracket to also be arranged as a corner connector.

[0020] The clearance is provided by a hole in the side wall of the ball socket.

[0021] Preferably, the embodiment with the relief cut in the areas that complement the relief cut around the ball socket is designed as follows: The ball joint is designed in the areas without the relief cut such that the central axis of the fastening element can be pivoted from an initial position in which the central axis is perpendicular to the rear surface by a pivot angle α of a maximum of 10°, in particular by a pivot angle α of a maximum of 8°, to the initial position.

[0022] Preferably, the fastening element can be pivoted transversely to the movement through the aforementioned pivot angle β by a transverse pivot angle of a maximum of 10°, and in particular by a transverse pivot angle of a maximum of 8°. This means that there is sufficient play between the free-cutting area and the fastening element, so that, starting from the aforementioned initial position, the fastening element can be pivoted not only into the free-cutting area but also transversely to it. That is to say, there is play between the side walls that laterally define the free-cutting area and the shaft section of the fastening element.

[0023] Preferably, the wall bracket also has a locking element with which, after the fastening element has been aligned, the aligned fastening element can be fixed or clamped to the anchor plate.

[0024] This allows the fastening element to be mechanically fixed to the anchor plate, enabling the installer to fix the set position and connect a mounting frame to the fastening element without further manipulation.

[0025] Preferably, the locking element is mounted on the fastening element and is located in front of the front surface, thus preventing the locking element from falling out of the ball socket through the aforementioned opening before the wall bracket is mounted.

[0026] Preferably, the locking element is designed as a lock nut with an internal thread. The lock nut is mounted with its internal thread on an external thread of the fastening element and is movable when rotated against the anchor element. When the lock nut moves against the anchor element, the bearing section on the fastening element side is clamped against the bearing section on the anchor element side. This clamping action secures the aligned fastening element to the anchor plate.

[0027] A locking structure between the fastening element and the locking element is particularly preferred.

[0028] Preferably, the locking mechanism prevents uncontrolled rotation of the locking element on the fastening element. Furthermore, the locking mechanism prevents the locking element from unintentionally releasing. The locking mechanism can be provided by at least one locking cam arranged on the locking element and by corresponding locking recesses arranged on the fastening element.

[0029] Preferably, the locking element and the anchoring element can be brought into contact with each other via respective spherical contact surfaces. This ensures that the set position of the fastening element can be maintained very precisely.

[0030] In a further development or a preferred embodiment, a retaining ring is embedded in the ball socket, which secures the anchor element and the fastening element relative to each other with respect to a separation movement.

[0031] Preferably, the retaining ring is partially embedded in the surface of the ball socket or ball head.

[0032] The retaining ring can be used instead of the locking element or in addition to the locking element.

[0033] Preferably, the retaining ring is designed as an element that increases the friction between the bearing section on the anchor element side and the bearing section on the fastening element side.

[0034] Preferably, the fastening section of the fastening element is an internal thread into which a fastening screw can be screwed. The internal thread can be an integral part of the fastening element, or it can be part of a threaded element whose thread function can be switched off for coarse adjustment of the position between the fastening screw and the fastening element, and whose thread function can be switched on for fine adjustment of the position between the fastening screw and the fastening element.

[0035] An assembly comprises at least one wall bracket as described above and a sanitary element with a storage opening into which the fastening element engages. The sanitary element is, for example, a mounting frame on which sanitary articles such as supply and drain pipes, cisterns, toilet bowls, urinals, washbasins, etc., can be stored. Furthermore, at least one sanitary article may be part of the assembly.

[0036] In a method for adjusting a wall bracket, the mounting element is pivoted relative to the anchor element via the ball joint to adjust its position. If a locking element is present, the mounting element is then fixed to the anchor element in a subsequent step.

[0037] Further embodiments are specified in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF PREFERRED EXECUTION FORMS

[0039] In the Figures 1 to 8 A first embodiment of a wall bracket 1 according to the invention is shown. Figures 9 to 11Figure 1 shows a further form of the wall bracket according to the invention in a second embodiment. Identical parts bear the same reference numerals, and reference is made to the respective descriptions.

[0040] According to both embodiments, the wall bracket 1 comprises an anchor element 2 and a fastening element 5. The wall bracket 1 serves to fasten a sanitary element, such as a mounting frame. Sanitary articles are stored on the sanitary element.

[0041] The anchor element 2 has a fastening section 3 for attaching the anchor element 2 to a supporting structure, which is not shown in the figures, and a bearing section 4 on the anchor element side. The supporting structure can be a wall or a fixed profile.

[0042] The fastening element 5 extends along a central axis M and has a bearing section 6 on its rear side. On its front side, the fastening element 5 has a fastening section 7 for attaching a sanitary fitting. In the illustrated embodiment, the fastening section 7 is in contact with a fastening screw 21. For this contact, the fastening section of the fastening element 5 has an internal thread 20. In the illustrated embodiment, the internal thread 20 is part of a threaded element 22, which is movable from a coarse adjustment position to a fine adjustment position. In the coarse adjustment position, the internal thread 20 is not engaged with the thread of the fastening screw 21, such that the fastening screw 21 is movable in translational motion along the central axis M.In the fine adjustment position, the internal thread 20 engages with the thread of the fastening screw 21, such that the fastening screw 21 can be tightened by turning it.

[0043] The fastening element 6 and the anchor element 2 are connected to each other via their respective bearing sections 4 and 6. The anchor element 2 has a rear surface 8, which allows it to be placed on the supporting structure. Furthermore, the anchor element 2 has a front surface 9, from which the fastening element 5 projects forward. The fastening section 3 of the anchor element 2 has an opening 23 through which a screw can be inserted, thus enabling the anchor element 2 to be firmly connected to the supporting structure.

[0044] As shown by the Figures 3 and 4As will be explained in more detail later, the fastening element 5 is designed to pivot relative to the anchor element 2. This pivotable design allows for easy compensation of unevenness in the supporting structure. In particular, the position of the fastening element 5 relative to the anchor element 2 can be aligned. In other words, the position of the central axis M can be adjusted accordingly.

[0045] In the Figure 1 An initial position is shown. In the initial position, the central axis M of the fastening element 5 is essentially perpendicular to the rear surface 8 of the anchor element 2. In the Figure 2 A rotated position is then shown. In the Figure 2 The fastening element 5 is pivoted accordingly from its initial position according to the Figure 1 The initial position is symbolized by axis A. The central axis M of the fastening element 5 is inclined at an angle to the rear surface 8 and at a pivot angle α to axis A.

[0046] In the Figure 3 An exploded view of the wall bracket 1 is shown, without the fastening screw 21. In the Figure 4 A corresponding cross-sectional view is shown. From the Figures 3 and 4 It becomes apparent that the bearing section 4 on the anchor element side and the bearing section 6 on the fastening element side are connected to each other via a ball joint 10. The ball joint 10 comprises a ball socket 11 and a ball head 12. Both the ball socket and the ball head are each designed as partial segments of balls. Because the bearing section 4 on the anchor element side and the bearing section 6 on the fastening element side are designed as a ball joint 10, the advantage already described above is achieved, namely that the fastening element 5 can be pivoted relative to the anchor element 2.

[0047] In the illustrated embodiments, the bearing section 4 on the anchor element side is designed as a ball socket or as a segment of a ball socket 11. The bearing section 6 on the fastening element side is designed accordingly as a ball head or as a segment of a ball head 12. Alternatively, the arrangement could be reversed.

[0048] The sectional views show that the ball socket 11 has an opening 13 extending towards the rear surface 8. The opening 13 is designed as an open opening towards the rear surface 8. The opening 13 has a clear width that is larger than the maximum outer diameter of the ball head 11. Furthermore, the ball socket 11 has an opening 14 opposite the opening 13, through which the fastening section 7 protrudes from the ball socket 11. The fastening element 5 is inserted into the ball socket 11 with the fastening section 7 leading and is guided through the opening 14. With further insertion, the ball head 12 then comes to rest in the ball socket 11. In all embodiments, the fastening element 5 is thus inserted into the ball socket 11 from the rear via the rear surface 8.Depending on the design of the ball socket 11, it would also be conceivable that the fastening element 5 could be inserted from the front, i.e., via the front surface 9. This is particularly relevant in applications where the tensile forces on the fastening element 5 are lower.

[0049] The ball socket 11 and the ball head 12 are designed such that a tensile force Z acting on the fastening element 5 is absorbed by the ball socket 11. The tensile force Z acts on the fastening element 5 along the central axis M and away from the anchor element 2. The tensile force is in the Figure 4 marked.

[0050] In the embodiments shown, the ball socket has a relief 24. The relief 24 is in the Figures 3 , 7 and 8more clearly shown. The clearance 24 is optional, meaning that it would also be conceivable to omit the clearance 24 in other variants. The clearance 24 is arranged such that, starting from the initial position in which the central axis M of the fastening element 5 is perpendicular to the rear surface 8, the fastening element 5 can be pivoted by a swivel angle β of a maximum of 50°. The swivel angle β is in the Figure 7 The corresponding diagram shows the opening 24. The clearance 24 allows the fastening element 5 to be moved into the opening 24 with a shaft section 25. The clearance 24 extends through a side wall that laterally defines the ball socket 11. The shaft section 25 is directly connected to the ball head 12. The clearance allows the fastening element 5 to be pivoted by the swivel angle β, enabling the wall bracket 1 to also be used as a corner connector.

[0051] Furthermore, the clearance 24 has a width that is greater than the shaft section 25, so that the fastening element 5 can be pivoted by a transverse swivel angle that is perpendicular to the movement of the aforementioned swivel angle β. Regarding the Figure 7 This means that the fastening element 5 can be pivoted not only by the swivel angle β, but also by the lateral swivel angle. The lateral swivel angle is determined starting from the in Figure 7 The position shown is relative to the surface of the drawing sheet. This means that the fastening element 5 can be moved backwards or forwards from the plane of the drawing sheet within the clearance between the cutout 24 and the shaft section 25. Preferably, the lateral swivel angle is a maximum of 8°, and particularly a maximum of 10°. This also allows for the compensation of corresponding unevenness.

[0052] The ball joint 10 is designed such that the central axis M of the fastening element 5, starting from its initial position in which the central axis M is perpendicular to the rear surface 8, can be pivoted by a swivel angle α of a maximum of 10°, in particular a maximum of 8°, relative to the initial position. This pivotability is independent of the pivotability through the relief cut 24. Preferably, the pivotability by the swivel angle α is provided in the embodiments with relief cut and also in the embodiments without relief cut.

[0053] In the Figure 4 The initial situation is shown. Here it can be clearly seen that the central axis M is perpendicular to the back surface 8. In the Figure 5 A first pivoted position of the fastening element 5 is shown. Here, the fastening element 5 is in a pivoted position such that the central axis M lies at a pivot angle α to the rear surface 8. In the Figure 6Another pivot position is shown. This further pivot position differs essentially in the direction of the pivot. In the pivot position according to Figure 5 The fastening element 5 was pivoted to the fastening section 3 of the anchor element 2 and in the Figure 6 The fastening element 5 was pivoted perpendicular to it.

[0054] The maximum pivoting range around the pivot angle α is essentially limited by the shaft section 25 and by the side edge 26 of the ball socket 11. The shaft section 25 abuts the side edge 26 accordingly.

[0055] Regarding the swivel angle α, pivoting within a cone is possible, the cone's apex being located at the center of the ball joint 10 and the cone's central axis being parallel to the central axis M of the fastening element 5 in the initial position. The cone has an opening angle that corresponds to twice the maximum swivel angle α. That is, the opening angle of the cone is a maximum of 20°, and in particular a maximum of 16°.

[0056] In the embodiments shown, the wall bracket 1 further comprises a locking element 15. The locking element 15 is located in the Figures 1 to 6The locking element 15 serves to secure the aligned fastening element 5 to the anchor plate 2. In the illustrated embodiment, the locking element 15 is designed as a locking nut with an internal thread 16. The locking nut is supported by its internal thread 16 on an external thread 17 of the fastening element 5. The locking nut is movable relative to the anchor element 2. When moved relative to the anchor element 2, the bearing section 6 on the fastening element side is clamped against the bearing section 4 on the anchor element side. This results in a clamping action between the ball socket 11 and the ball head 12.

[0057] In the illustrated embodiment, a locking structure 18 is provided between the fastening element 5 and the locking element 15. The locking structure 18 comprises two opposing locking cams 27, which are integrally formed on the locking element 15, and locking recesses 28 provided on the fastening element 5. The locking cams 27 engage in the locking recesses 18. When the locking element 15 is moved, the engagement force between the locking cam 27 and the locking recess 28 must be overcome. The locking structure 18 has the advantage that unintentional release of the locking element 15 can be prevented.

[0058] In the illustrated embodiment, the locking element 15 and the anchor element 2 are in contact with each other via spherical contact surfaces 18. These spherical contact surfaces 18 ensure that a corresponding fixation is permitted in any orientation of the fastening element 5, without negatively affecting its aligned position. The spherical contact surface 18 on the side of the anchor element 2 surrounds the ball socket 11 on the outside. The center of the spherical contact surfaces 18 and the ball socket 11, or the ball head 12, is identical.

[0059] In the embodiments of the Figures 9 to 11A retaining ring 19 is embedded in the ball socket 11. The retaining ring 19 sits in a circumferential groove 29, which adjoins the ball socket 11 or may be part of the ball socket 11. The retaining ring 19 prevents the fastening element 5 from falling out of the ball socket to the rear, i.e., through the opening 13. The retaining element 19 is preferably a plastic ring that can be pressed into the groove. The retaining ring 19 can also be designed as an element that increases the friction between the bearing section 4 on the anchor element side and the bearing section 6 on the fastening element side. This creates a kind of pre-fixation for the installer.

[0060] In further preferred embodiments, it is also conceivable that the retaining ring 19 could also be attached to the embodiment according to the Figures 1 to 8can be used. This is essentially for the purpose of creating a structure in which little resistance is noticeable when aligning the fastening element. REFERENCE MARK LIST
