TECHNICAL AREA
The present invention relates to a thread unit for a sanitary mounting structure according to claim 1, a sanitary mounting structure according to claim 15 and a method for assembling the sanitary mounting structure according to claim 18.
STATE OF THE ART
From EP 3 428 353 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.
EP 3 404 152 also discloses a wall bracket for a sanitary article, the threaded element here being fixed to the mounting frame by a plug-in part.
The assembly of the known from the prior art wall brackets on a mounting frame is complicated in many ways. In the technical teaching of EP 3 404 152, a corresponding plug-in part must be used, which increases the assembly effort. This regardless of whether the assembly is carried out at the factory or on site.
DISCLOSURE OF THE INVENTION
Based on this prior art, the invention is based on an object of specifying a thread unit for a sanitary mounting structure which overcomes the disadvantages of the prior art
[0006] This object is achieved by the subject matter of claim 1. Accordingly, it comprises a thread unit for a sanitary mounting structurea screw extending along a central axis with a threaded section, a bearing section and an actuating section,a bearing element with a bearing opening in which the screw with the bearing section is rotatably mounted about the central axis and is mounted displaceably from a first position to a second position, andat least one clamping element which is fixedly mounted on the bearing element with respect to the central axis and has at least one clamping section for clamping the bearing element to a mounting structure.
The at least one clamping portion is by moving the screw from the first position to the second position radially to the central axis outward from a mounting position in which the threaded unit is displaceable relative to the mounting structure, in a clamping position in which the threaded unit to the mounting structure is firmly clamped, movable.
Due to the interaction between the screw and the at least one clamping section, a simple clamping structure can be provided between the thread unit and the sanitary mounting structure. In particular, a simple clamping structure can be provided without additional elements having to be arranged.
The clamping of the thread unit on the assembly structure also has the advantage that further assembly steps can be carried out easily by one person without the aid of further installers.
The expression "firmly clamped or firmly clamped" is understood to mean that the thread unit as such is mechanically connected to the bearing element with the mounting structure in a mechanically fixed manner and preferably without play. It is a mechanical clamping. After the connection has been made, the screw can be turned with respect to the bearing element.
The screw typically acts on an anchor element with an internal thread into which the screw engages, the anchor element being firmly connectable to the building. The anchor element can be designed in various ways. For example as a plate or as a dowel. Via the connection from the anchor plate via the thread unit to the mounting structure, the mounting structure can be aligned in its position and fastened to the building.
The clamping element and the screw are preferably made of a metallic material, while the bearing element is preferably made of plastic.
The operating section includes a structure with which the screw can be operated by means of a tool. A hexagon socket, a slot or a cross slot may be mentioned here as an example. Other structures are also conceivable. The actuating section is accessible from outside the bearing element.
Preferably, viewed with respect to the central axis, at least opposing clamping sections are provided. There are preferably four clamping sections. In other variants, only one clamping section can be present.
Preferably, the bearing section has a conical surface area which acts on the at least one clamping section in such a way that the at least one clamping section can be moved from the mounting position into the clamping position when the screw is moved from the first position to the second position.
With the conical surface area, a reliable displacement of the at least one clamping section can be achieved when the screw is advanced into the second position.
[0017] The conical surface area is preferably designed to run around the central axis. The relative displacement during the movement of the screw from the first position to the second position results in a relative displacement between the conical surface area and the clamping sections, the conical surface area pressing the clamping sections radially outward as seen from the central axis.
Starting from the first position, the diameter of the conical surface area acting on the at least one clamping element increases with increasing advance of the screw and then reaches the maximum diameter when the screw is in the second position.
The conical surface area is preferably adjoined by a cylindrical surface area with a constant diameter, the at least one clamping section in the second position coming to rest at least partially on the cylindrical surface area.
By resting on the cylindrical surface area there is the advantage that the clamping sections are securely mounted and their clamping position remains.
The bearing section of the screw preferably has a cylindrical bearing area with which the screw is mounted in the bearing opening.
The cylindrical bearing area preferably has a constant diameter.
Preferably, the bearing portion of the screw further has a circumferential recess around the central axis, at least one latching element which is fixed with respect to its position relative to the bearing element engages in the recess when the screw is in the second position. As a result, the screw to the bearing element is secured with respect to displaceability along the central axis. Depending on the embodiment, the locking element can be part of the bearing element or part of the clamping element.
The engagement of the locking element is such that the screw is fixed with respect to a movement along the central axis. The screw can still be pivoted about the central axis through the circumferential recess.
The expression that the locking element is fixed to the bearing element is to be understood that the locking element is either part of the bearing element or that the locking element is provided by a further element which is connected to the bearing element. The locking element can particularly preferably be part of the clamping element.
[0026] The at least one clamping section preferably has a free end. A locking lug is arranged at the free end. The bearing element and / or the clamping element have a stop surface, an intermediate space being formed between the latching lug and the stop surface, in which a wall of the mounting structure can be received.
As a result, the at least one clamping element is fixedly mounted on the bearing element.
The free end and the locking lug extend out of the bearing opening and preferably protrude from the bearing opening.
Preferably, the clamping portion is designed to be elastically resilient, wherein when the screw is moved from the second position into the first position, the clamping portion is moved from the clamping position into the assembly position. This ensures that the thread unit can be dismantled.
The clamping element preferably has a sleeve section extending around the central axis, from which the at least one clamping section extends away at the end face, the clamping element with the sleeve section being in contact with the bearing element or being mounted on the bearing element.
In a first embodiment, the clamping element is mounted with the sleeve section in the bearing opening.
Preferably, the clamping element according to the first embodiment has a latching section which protrudes radially outward from the sleeve section and engages in a latching receptacle arranged on the bearing element, such that the clamping element is fixedly supported on the bearing element with respect to a movement along the central axis.
In the first embodiment, the locking element securing the screw with respect to the movement along the central axis is preferably part of the clamping element and extends radially inward from the sleeve section. In the first embodiment, the latching element is part of the clamping element. Alternatively, the latching element can also be part of the bearing element.
According to a second embodiment, the sleeve section at least partially engages around the bearing element on the outside. This encompassing has the advantage that an outside bearing can be provided which can be viewed by the installer.
In the second embodiment, the locking element securing the screw with respect to the movement along the central axis is preferably part of the bearing element and extends radially inward from the bearing opening.
In a third and fourth embodiment, the at least one clamping element with its clamping sections is pivotably mounted on the bearing element.
Preferably, according to all embodiments, the bearing element has a bearing surface on the outside with which the bearing element is mounted in a through opening of an assembly structure.
An assembly structure comprises at least one thread unit according to the above description and at least one assembly profile with a through opening, the at least one clamping section providing a clamping effect in the area of the through opening.
Preferably, the at least one clamping section is positioned in the assembly position in such a way that it can be guided through the through opening. The maximum extent of the clamping sections radially to the central axis is accordingly smaller than the inside diameter of the through opening. After the screw has been moved into the second position, the maximum expansion of the clamping sections also increases.
Preferably, the mounting profile is a hollow profile with profile walls, wherein the through opening extends through two opposing profile walls, the threaded unit with the threaded portion of the screw is passed through both through openings, and the clamping portion has a clamping effect in the region of one of the two Provides through openings. The mounting profile can, however, be an open profile or a sheet metal, in particular a sheet metal strip.
A method for assembling a mounting structure according to the above description is characterized in thatthat in a first step the thread unit with the bearing element is positioned in the through opening,that in a second step the screw is moved from the first position to the second position, the movement of the screw moving the at least one clamping section of the at least one clamping element from the mounting position into the clamping position.

DESCRIPTION OF PREFERRED EMBODIMENTS
In FIGS. 1a to 5c, a thread unit 1 for a sanitary mounting structure 10 is shown. The thread unit 1 essentially serves to secure a mounting structure 10, such as a mounting frame, on a wall. The thread unit 1 is connected to the mounting structure 10 and then connected to a fastening element which is already mounted on a wall. Such a fastening element can be a dowel or a wall anchor, which are not shown in the figures. The mounting structure is essentially used to store a sanitary article, such as a toilet or a washstand.
Five different embodiments of the thread unit 1 according to the invention are shown in the figures. The thread unit 1 comprises a screw 2 with a central axis M, a threaded section 3, a bearing section 4 and an actuating section 5. Furthermore, the threaded unit 1 comprises a bearing element 6 with a bearing opening 7 in which the screw 2 with the bearing section 4 around the central axis M is rotatably mounted and displaceable along the central axis M from a first position A to a second position B. The thread unit 1 further comprises at least one position element 6 and a clamping element 8, which is fixedly mounted on the bearing element, with at least one clamping section 9 for the clamping attachment of the bearing element 6 to an assembly structure 10.
In Figures 1b, 2b, 3b, 4a and 5a, the screw 2 is each in its first position A. Starting from this first position A, the screw 2 can be moved into a second position B. The second position B is shown in Figures 1c, 2c, 3c, 4b and 5c. When moving from the first position A to the second position B, the screw 2 is moved along the central axis M. This involves a translational movement in the direction or along the central axis M. The at least one clamping section 9 is moved radially outward to the central axis M by moving the screw 2 from the first position A to the second position B. The clamping section 9 moves from a mounting position C, which is shown in Figures 1b, 2b, 3b, 4a and 5a, into a clamping position B, which is shown in Figures 1c, 2c, 3c, 4b and 5c. In the assembly position C, the thread unit 1 can be inserted into a through opening 25 on the assembly structure 10. In the clamping position D, the thread unit 1 is mechanically clamped to the mounting structure 10. For this purpose, the at least one clamping section 9 is pressed radially outwards in relation to the central axis and is clamped to the mounting structure 10 in the area of the through opening 25.
At least two clamping sections 9 are preferably present. The clamping sections 9 are preferably arranged distributed around the central axis at equal intervals.
In all embodiments, the bearing section 4 has a conical surface area 11. The conical surface area 11 acts on the at least one clamping section 8 in such a way that the at least one clamping section 8 can be moved from the mounting position C to the clamping position D when the screw 2 is moved from the first position A to the second position B. It can be clearly seen from FIGS. 1b, 2b, 3b, 4a and 5a that a conical surface area 11 rests against the at least one clamping section 8 on the inside. When the screw 2 is advanced from the first position A into the second position B, the conical surface area 11 is also advanced and the outer diameter of the conical surface area 11 acting on the at least one clamping section 8 increases with increasing advance, with the at least one clamping section 8 at the same time is pressed radially outwards to the central axis, as shown in Figures 1c, 2c, 3c, 4b and 5c. This design has the advantage that the thread unit 1 with the clamping section 9 can be passed through the through opening 25 and that the corresponding clamping sections 9 can be moved radially outward over the diameter of the through opening 25 on the rear end of the through opening 25.
In the embodiments shown, the conical surface area 11 is adjoined by a cylindrical surface area 12 with a constant diameter. In the second position B, the at least one clamping section 9 lies at least partially on the cylindrical surface area 12. That is to say, the at least one clamping section 9 comes to lie on a determined diameter.
The bearing section 4 of the screw 2 has a cylindrical bearing area 13 with which the screw 2 is mounted in the bearing opening 7. In the embodiments shown, the cylindrical bearing area 13 adjoins the actuating section 5.
The bearing section 4 also has a recess 14 running around the central axis M. The recess 14 works together with a latching element 15. The locking element 15 engages in the recess 14 when the screw 2 is in the second position B. The locking element 15 is firmly positioned in relation to the bearing element 6. Various variants are conceivable with regard to the locking element 15. According to the first variant, which is shown in FIGS. 1 a to 1 c, the latching element 15 is part of the clamping element 8, which in turn is fixedly mounted to the bearing element 6. The locking element 15 engages radially from the outside into the circumferential recess 14 of the screw 2. This intervention is shown in more detail in FIG. 1c. According to a second variant, which is shown in FIGS. 2a to 3c, the latching element 15 is an integral part of the bearing element 6 and protrudes radially from the outside into the bearing opening 7. The engagement in the circumferential recess 14 is shown in Figures 2c and 3c.
In all embodiments, the at least one clamping section 9 has a free end 16. A locking lug 17 is arranged at the free end 16. The bearing element 6 and / or the clamping element 8 each have a stop surface 18. An intermediate space 19 is formed between the locking lug 17 and the stop surface 18, in which a wall 20 of the mounting structure 10 can be received.
In the first embodiment according to FIGS. 1a to 1c, the stop surface 18 is part of the bearing element 6. The stop surface 18 forms the front face of the bearing element 6. The at least one clamping section 9 protrudes with its free end 16 and the locking lug 17 from the bearing opening 7 beyond the front end face 18.
In the other embodiments according to FIGS. 2a to 5c, the stop surface 18 is formed by the clamping element 8 itself. For this purpose, the at least one clamping section 9 has a corresponding stop surface 18.
In the embodiments according to FIGS. 1a to 3c, the at least one clamping section 9 is designed to be elastically resilient. When the screw 2 is moved from the second position B to the first position A, the clamping section 9 is moved back from the clamping position B to the mounting position C. This elastic, deformable suspension is advantageous when it comes to dismantling the thread unit 1 from the assembly structure 10.
According to the first, the second and the third embodiment, the clamping element 8 has a sleeve section 21 extending around the central axis M. The at least one clamping section 9 extends away from the sleeve section 21 at the end face. The clamping element 8 is in contact with the sleeve section 21 with the bearing element 6 or is mounted on the bearing element 6.
In the first embodiment according to FIGS. 1 a to 1 c, the clamping element 9 is mounted with the sleeve section 21 in the bearing opening 7. Furthermore, the clamping element 8 has a latching section 22, which projects radially outward from the sleeve section 21 and engages in a latching receptacle 23 arranged on the bearing element 6. The engagement is such that the clamping element 8 is fixedly mounted on the bearing element 6 with respect to a movement along the central axis M. The clamping element 8 is secured to the bearing element 6 via this engagement. The locking element 15 which secures the screw 2 with respect to the movement along the central axis M is likewise arranged on the sleeve section 20. The locking element 15 protrudes radially from the sleeve section 20 to the central axis M.
In the embodiment shown according to FIGS. 1a to 1c, the screw 2 also extends through the sleeve section 21.
According to the second embodiment and the third embodiment, the sleeve section 21 has a diameter which at least partially engages around the bearing element 6 on the outside. As a result of this encompassing, the sleeve section 21 is firmly mounted on the bearing element 6. The bearing element 6 has corresponding structures on the outside, on which the sleeve section 21 is mounted. The at least one clamping section 9 protrudes axially from the sleeve section 21 in the direction of the central axis M. These clamping sections 9 are then elastically deformable accordingly.
In the embodiments according to Figures 4a to 5c, the at least one clamping element clamping section 9 is pivotably mounted on the bearing element. According to the fourth embodiment, the clamping elements are on the outside of the bearing element 6. In the fifth embodiment, the clamping elements 8 are arranged to be pivotable about an axis.
In all embodiments, the bearing element 6 has a bearing surface 24 on the outside. With the bearing surface 24, the bearing element 6 can be stored in a through opening 25 of the mounting structure 10.
A sanitary mounting structure 10 comprises a thread unit 1 as described above. The sanitary mounting structure 10 further comprises at least one mounting profile 26 with a through opening 25. The mounting profile 26 has two spaced apart profile walls 27 through which the through opening 25 extends.
