[0004] Wall mounting device for an installation element of a sanitary installation, and installation element with such a wall mounting device.
[0005] The present invention relates to a wall mounting device for an installation element for sanitary equipment, and to an installation element comprising such a wall mounting device. The installation element allows the sanitary equipment, for example a toilet, bidet, or urinal, to be mounted to a building wall and / or a building floor.
[0006] An installation element typically comprises a mounting frame that is attached to a load-bearing wall using at least one wall fixing device. The wall fixing device serves to align the installation element at a defined distance from the wall and to ensure stable fixation. Furthermore, the wall fixing device allows the installation element, or rather the mounting frame, to be aligned vertically.
[0007] With conventional wall mounting devices, the connection between the installation element and the wall is often made using a threaded rod that is screwed into a corresponding mounting bracket. In practice, however, the installation of such devices has proven to be time-consuming.
[0008] Another problem with existing wall mounting devices lies in the large number of individual parts required for installation. These often consist of several separate components that must be assembled on-site. This not only increases the installation effort but also carries the risk of small parts being lost or incorrectly installed. Furthermore, with known mounting solutions, tools are required to precisely adjust the position of the installation element. Grohe AG
[0009] P24-0645W001
[0010] - 2 - The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and, in particular, to provide a wall mounting device for an installation element with which the installation element can be mounted on a wall with minimal effort. Furthermore, an installation element for a sanitary installation is also to be provided, the wall mounting device of which enables the installation element to be mounted with minimal effort.
[0011] These problems are solved with a wall mounting device and an installation element according to the features of the independent claims. Further advantageous embodiments of the invention are specified in the dependent claims. It should be noted that the features listed individually in the claims can be combined with one another in any technologically meaningful way and define further embodiments of the invention. Furthermore, the features specified in the claims are further specified and explained in the description, which also presents further preferred embodiments of the invention.
[0012] This is achieved by a wall mounting device for an installation element of a sanitary facility, which has at least the following features:
[0013] - a threaded rod;
[0014] - a threaded sleeve with a receptacle for the threaded rod, wherein the receptacle extends along a longitudinal axis of the threaded sleeve and has a thread root; and
[0015] - a rotating ring that is rotatable relative to the threaded sleeve between an open position and a closed position, wherein the rotating ring releases the threaded rod in the open position so that the threaded rod can be adjusted in the receptacle without engaging the thread root parallel to the longitudinal axis, and wherein the rotating ring presses the threaded rod into the thread root in the closed position so that the threaded rod can be adjusted in the receptacle by rotating the threaded sleeve parallel to the longitudinal axis.

[0018] The installation element can have a mounting frame. The mounting frame can, for example, comprise at least one Meta II profile. Furthermore, the mounting frame can, for example, have a (particularly vertical) first metal profile and a (particularly vertical) second metal profile, which are connected to each other via at least one (particularly horizontal) (Meta 11) crossbar. The first metal profile, the second metal profile, and / or the at least one (metal) crossbar can, for example, be connected to each other via a welded or bolted connection. Alternatively, the first metal profile, the second metal profile, and / or the at least one (metal) crossbar can be formed in one piece. The mounting frame has (particularly in an operational state, after its attachment to a wall or...The mounting frame (after its attachment to a building wall, on a building floor and / or in a horizontal direction) has a frame width of, for example, 400 mm to 600 mm, preferably 490 mm to 510 mm, and particularly preferably (essentially) 500 mm. The mounting frame can be height-adjustable. This can mean that the frame height of the mounting frame is adjustable (especially in a vertical direction). For this purpose, the mounting frame can have at least one adjustable foot. For example, the mounting frame can have a first foot that is adjustable on and / or in the (vertical) first metal profile. For example, the mounting frame can have a second foot that is adjustable on and / or in the (vertical) second metal profile. The frame height can be, for example, 750 mm to 1,400 mm, preferably 1,130 mm to 1,330 mm. The frame height can change (especially after the installation element has been mounted).of the mounting frame on the wall and / or on the building floor) in the vertical direction.
[0019] The installation element or mounting frame can be attached to the wall, particularly with a gap, using at least one wall mounting device. The wall can be, for example, a building wall, a structural wall, or a drywall partition. The mounting frame can be positioned or attached to the building floor. (According to Grohe AG)
[0020] P24-0645W001
[0021] -4 -
[0022] After the mounting frame is attached to the wall, the installation element can be at least partially concealed by a partition wall. This partition wall can consist, at least partially, of at least one panel, at least one plasterboard, at least one drywall panel, and / or at least one tile.
[0023] The installation element can include at least one fastening element for a sanitary fixture. The sanitary fixture could be, for example, a toilet, bidet, or urinal. This fastening element can be attached to the mounting frame or the mounting frame's crossbar. The fastening element could, for example, be a threaded bolt. The sanitary fixture can be screwed to, or be screwed to, the mounting frame using this fastening element. The fastening element can extend through the wall.
[0024] The installation element may include a cistern for flushing the sanitary fixture, which can be attached to the mounting frame. The flushing fluid may be, in particular, water. The flushing fluid can be supplied to the cistern from a flushing fluid source, such as a public water supply network. The cistern may be made at least partially of plastic and / or be manufactured as an injection-molded plastic part. The cistern has a reservoir for the flushing fluid, which may, for example, have a capacity of 3 to 9 liters. Furthermore, the reservoir may have an opening at the top, which may, for example, be at least partially closable by a lid.
[0025] The cistern may have a fill valve for filling it with flushing fluid. This fill valve is primarily used for automatically filling the cistern or automatically refilling it after a flush. The cistern may also have a flush valve. This flush valve allows control over the release of flushing fluid to the toilet. The release of flushing fluid to Grohe AG

[0028] Sanitary facilities can be flushed via a flushing fluid line. The flushing fluid is used to remove bodily waste from the sanitary facility. The flushing fluid and / or the bodily waste can be discharged from the sanitary facility, particularly via a wastewater line, into a sewer system. The flushing fluid line can be, for example, a pipe. The fill valve and / or flush valve can be, for example, an electrically operated valve, a solenoid valve, or a manually operated valve. The fill valve can be actuated by a float valve. The float valve can, in particular, float on the flushing fluid in the cistern. Furthermore, the float valve is raised by the flushing fluid when the fluid level rises and lowered when the fluid level falls.The liquid level of the flushing fluid in the reservoir can be lowered. The fill valve float closes the fill valve when the flushing fluid in the reservoir reaches a set level. If the flushing fluid level drops, for example, when flushing the shower toilet, the fill valve float opens the fill valve until the flushing fluid level in the reservoir reaches the set level again. The flush valve can be operated by a user of the shower toilet, for example, via an actuator. The actuator could, for example, be a button.
[0029] The wall mounting device may include a wall element for attachment to the wall. The wall element may be made at least partially of plastic and / or metal, for example, die-cast zinc. The wall element may be at least partially plate-shaped. The wall element may have a front and a back. The back may form a wall contact surface for the wall element. The wall element may have at least one mounting opening through which the wall element can be attached to the wall, for example, via a screw and dowel connection. The at least one mounting opening may be designed as an elongated hole. The wall element can be attached to the wall, in particular, via its wall contact surface. The wall element may have a hinge socket. ZurGrohe AG

[0031] - 6 -
[0032] The joint socket can be formed by the wall element having a joint opening. The joint opening can extend from the front to the back of the wall element.
[0033] The wall mounting device comprises a threaded rod that extends along a longitudinal axis (in particular a straight one), for example from a first longitudinal end of the rod to a second longitudinal end. The threaded rod has an external thread at least partially along its longitudinal axis. The threaded rod can have a length of, for example, 100 mm to 250 mm (in particular along its longitudinal axis) and / or a diameter of, for example, 4 mm to 20 mm (in particular perpendicular to its longitudinal axis). The threaded rod can be made at least partially of plastic and / or metal. The threaded rod can be attached to the wall element at its first longitudinal end. The threaded rod can extend through the hinge opening of the wall element.
[0034] The threaded rod can have a ball joint at its first longitudinal end, which can be arranged, in particular, at the first longitudinal end of the threaded rod. The ball joint can be a spherical joint. The ball joint can have a diameter of, for example, 5 mm to 30 mm (especially perpendicular to the longitudinal axis of the rod). The ball joint can be mounted in the socket. The ball joint and the socket can form a ball joint. The socket can have at least one sliding surface on which the ball joint can slide. The ball joint can be mounted in the socket such that the threaded rod is pivotable around the ball joint relative to the wall element. For example, the threaded rod can be pivotable around the ball joint within a conical pivot range.In its neutral position, the threaded rod's longitudinal axis can align with a center axis of the pivot range. In the neutral position, the rod's longitudinal axis can be oriented orthogonally to the wall contact surface of the wall element. From the neutral position, the threaded rod can be rotated around the ball joint in any direction, for example, by Grohe AG.
[0035] P24-0645W001
[0036] - 7 -
[0037] The second longitudinal end of the threaded rod can be pivoted 10° to 45°, preferably 10° to 30°, and particularly preferably (essentially) 20°. The second longitudinal end of the threaded rod can be pivoted on a circular path around the ball joint and / or around the center axis of the pivoting range. The center axis can pass through the center point of the circular path. Twisting or rotation of the threaded rod about its longitudinal axis is prevented, for example, by a positive fit between the ball joint and the socket.
[0038] The ball joint formed by the socket and the ball head allows the threaded rod to be aligned in such a way that sloping and / or uneven walls can be compensated for.
[0039] The wall mounting device has a threaded sleeve with a receptacle for the threaded rod. The threaded sleeve can extend along a longitudinal axis (especially a straight one), for example, from a first longitudinal end to a second longitudinal end. The threaded sleeve can have a length (especially along the longitudinal axis) of, for example, 100 mm to 250 mm and / or a diameter (especially perpendicular to the longitudinal axis) of, for example, 8 mm to 60 mm. The threaded sleeve can be made at least partially of plastic and / or metal. The threaded sleeve is at least partially tubular or pipe-shaped.
[0040] The receptacle for the threaded rod is formed, in particular, at the first longitudinal end of the threaded sleeve. The receptacle extends from this first longitudinal end of the threaded sleeve, in particular parallel to its longitudinal axis, into the threaded sleeve. The receptacle can have a length (parallel to the longitudinal axis) of, for example, 50 mm to 250 mm. The length of the receptacle can correspond to the length of the threaded sleeve. In other words, the receptacle can extend completely through the threaded sleeve along its longitudinal axis. The threaded sleeve can have a diameter (perpendicular to the longitudinal axis) of, for example, 6 mm to 25 mm. The diameter of the receptacle can be larger (at least in one direction) than the diameter of the threaded rod. The receptacle can be a Grohe AG
[0041] P24-0645W001
[0042] - 8 -
[0043] The slot should be designed so that the threaded rod can be guided in the receptacle orthogonally to the longitudinal axis with some play.
[0044] The receptacle has a thread root. The thread root is a region of the receptacle in which an internal thread is formed. The internal thread extends circumferentially around the receptacle and / or along an inner wall of the receptacle, not by 360° around the longitudinal axis, but, for example, only by 20° to 180°, preferably 90° to 180°, around the longitudinal axis. The thread root can be designed as a semicircular recess, a concave half-shell, partially cylindrical, semi-cylindrical, and / or trough-shaped. The receptacle can be designed, in particular, as a shell, partially cylindrical, semi-cylindrical, or trough-shaped in the region of the thread root. The threaded sleeve or the receptacle can be partially open orthogonally to the longitudinal axis in the region of the thread root.The thread root can have a thread root length of, for example, 10 mm to 250 mm (parallel to the longitudinal axis), preferably 10 mm to 60 mm, and / or a thread root radius of, for example, 2 mm to 10 mm (orthogonal to the longitudinal axis).
[0045] The wall mounting device has a rotating ring. The rotating ring is, in particular, annular, sleeve-shaped, polygonal, square, or tubular. The rotating ring can be made at least partially of plastic and / or metal. The rotating ring is, in particular, rotatably mounted on the threaded sleeve about an axis of rotation. The axis of rotation can correspond to the longitudinal axis. The rotating ring is rotatable relative to the threaded sleeve between an open position and a closed position. For example, the rotating ring can be rotatable between the open and closed positions by 45° to 180°, by 80° to 100°, and particularly preferably by (essentially) 90° about the axis of rotation or the longitudinal axis. The rotating ring can have at least one rotation stop that limits the angle of rotation of the rotating ring. The rotating ring can have at least one snap hook with which the rotating ring can be fastened to the threaded sleeve.The rotary ring can have at least one locking hook with which the rotary ring can be secured in the closed position. The at least one locking hook can be secured in the closed position. Grohe AG.

[0048] For example, it engages in a groove of the threaded sleeve. The rotating ring can have a lever with which at least one locking hook (especially from the groove) can be released, so that the rotating ring can be adjusted from the closed position to the open position.
[0049] In the open position, the rotating ring releases the threaded rod in the receptacle, allowing the rod to be adjusted parallel to its longitudinal axis without engaging the thread base. Specifically, in the open position, the threaded rod can be lifted out of its thread base perpendicular to the longitudinal axis, allowing it to be moved or adjusted parallel to the longitudinal axis within the receptacle (in particular, freely and / or continuously). This enables coarse adjustment of the threaded rod within the receptacle or of the distance between the wall and the installation element.
[0050] In the closed position, the rotating ring presses the threaded rod into the thread root, so that the threaded rod, or rather its external thread, engages with the thread of the thread root. The rotating ring may have a ramp, particularly on an inner circumferential surface, over which the threaded rod can be pressed (directly or indirectly) into the thread root when the rotating ring is turned from the open to the closed position. In the closed position, the threaded rod cannot disengage from the thread root (especially perpendicular to the longitudinal axis). In the closed position, the threaded rod in the receptacle can be adjusted relative to the threaded rod parallel to the longitudinal axis by rotating the threaded sleeve. This allows for fine adjustment of the threaded rod in the receptacle or of the distance between the wall and the installation element.
[0051] The thread root can have a partial thread. A partial thread is an internal thread that only extends partially around the longitudinal axis in one circumferential direction.
[0052] The threaded sleeve can have at least one guide flange for the swivel ring. This guide flange can be formed integrally with the threaded sleeve. Grohe AG
[0053] P24-0645W001
[0054] - 10 -
[0055] For example, the threaded sleeve can have a first guide flange and a second guide flange. The first guide flange and the second guide flange can each be formed at a longitudinal thread root end of the thread on the threaded sleeve. The first guide flange can be formed at the first longitudinal end of the threaded sleeve. The rotating ring can be rotatably mounted on at least one guide flange.
[0056] The threaded sleeve can have at least one drive geometry for rotating the threaded sleeve about its longitudinal axis. This drive geometry can be designed as a pivot, which can extend from the threaded sleeve, in particular, perpendicular to its longitudinal axis. The drive geometry can be formed integrally with the threaded sleeve. The threaded sleeve can be rotated about its longitudinal axis by an installer, particularly without tools, via the drive geometry, during installation of the mounting element on the wall and / or for adjusting the distance between the wall and the mounting element. The threaded sleeve can also be rotated by the installer, particularly without tools, via the drive geometry for fine-tuning the threaded rod in the receptacle and / or for fine-tuning the distance about its longitudinal axis.
[0057] The wall mounting device may include a clamping element for the threaded rod. The clamping element may be mounted on the threaded sleeve in the area of the receptacle and / or in the area of the thread root, allowing movement perpendicular to the longitudinal axis. For example, the clamping element may be arranged and / or mounted (parallel to the longitudinal axis) between the first guide flange and the second guide flange. The clamping element may be located within the rotating ring or between the rotating ring and the receptacle. In the closed position, the rotating ring can press the threaded sleeve into the thread root via the clamping element. Grohe AG
[0058] P24-0645W001
[0059] - 11 -
[0060] The clamping element can have at least one rib for the threaded rod. The clamping element can, for example, have a retaining rib by which the threaded rod can be pressed into the thread root and / or by which the threaded rod is held in place in the thread root. The clamping element can have at least one (especially elastic) spring rib that conforms to the threaded rod (especially in the closed position) and / or that can press the threaded rod into the thread root without play.
[0061] The threaded sleeve can have a fastening section for attaching the wall mounting device to the installation element. The fastening section can be located at the second longitudinal end of the threaded sleeve. The fastening section can have a plurality of flanges, which are spaced apart from each other, in particular parallel to the longitudinal axis. The fastening section allows the threaded sleeve to be fastened, in particular, in a mounting opening of the installation element or the mounting frame. The fastening section is designed, in particular, such that the threaded sleeve is rotatable in the mounting opening (relative to the installation element and / or the mounting frame).
[0062] The fastening section can include a clamping ring that is resiliently mounted parallel to the longitudinal axis. The clamping ring can extend along a (particularly straight) longitudinal axis from a first longitudinal end to a second longitudinal end. The clamping ring can have at least one stop and / or at least one spring tab, especially at the first longitudinal end. The clamping ring can have multiple stops and / or multiple spring tabs at the first longitudinal end. The clamping ring is resiliently mounted in the fastening section, particularly by means of the at least one spring tab, parallel to the longitudinal axis, for example with a spring travel of 0.5 mm to 5 mm, preferably 0.5 mm to 2 mm, and most preferably (essentially) 1 mm.The clamping ring can have at least one fastening hook at its second longitudinal end for attaching the clamping ring to the mounting section. The clamping ring enables a backlash-free fastening of the Grohe AG.

[0065] The threaded sleeve in the mounting opening of the installation element or mounting frame and / or the compensation of manufacturing tolerances. In addition, the clamping ring can facilitate the insertion of the fastening section or the threaded sleeve into the mounting opening.
[0066] The fastening section may include a fastening clip for attaching the wall mounting device to the installation element. The fastening clip may have two legs in which a (particularly round) cutout for the threaded sleeve is formed. The fastening clip may be able to be inserted (particularly positively) onto the fastening section of the threaded sleeve via the cutout. The fastening clip allows the threaded sleeve to rotate easily in the mounting opening of the installation element or the mounting frame, particularly about its longitudinal axis. The threaded sleeve may be inserted into the mounting opening of the installation element or the mounting frame via the fastening clip. The fastening section of the threaded sleeve may be secured in the mounting opening with the fastening clip. The fastening clip may have a tab. The fastening clip or the tab may have at least one locking mechanism.The retaining clip or the legs of the retaining clip can have at least a second detent. The retaining clip or the mounting section of the threaded sleeve can be secured in the mounting opening by means of a snap-fit connection using the at least one first detent and / or the at least one second detent. Each leg can have at least one recess through which the retaining clip can be removed from the mounting opening using a release tool (e.g., pliers).

The wall mounting device 1 comprises a threaded sleeve 6 which extends in a sleeve-like shape along a (straight) longitudinal axis 8 from a first longitudinal end 29 to a second longitudinal end 30.
[0090] The threaded sleeve 6 has a receptacle 7 at its first longitudinal end 29 for a [missing information] as shown in Fig.
[0091] The threaded rod 5 of the wall mounting device 1 is shown in Figure 4. The receptacle 7 comprises a threaded base 9, which is shaped as a semicircular recess, a concave half-shell, a partial cylindrical shape, a semi-cylindrical shape, and / or a trough shape. A partial thread 13 is formed in the threaded base 9. The receptacle 7 extends along the longitudinal axis 8 from a first guide flange 14 to a second guide flange 15 of the threaded sleeve 6. The first guide flange 14 is formed at the first longitudinal end 29 of the threaded sleeve 6. A swivel ring 10 can be attached to the guide flanges 14 and 15, allowing the swivel ring 10 to rotate about the longitudinal axis 8. A clamping element 17 is arranged between the swivel ring 10 and the receptacle 7 on one side and between the guide flanges 14 and 15 on the other.
[0092] The threaded sleeve 6 has a fastening section 18 at its second longitudinal end 30. The fastening section 18 comprises a clamping ring 19 and a fastening clip 20.

[0097] The mounting opening 31 of the mounting frame 21 is attached. The threaded rod 5 extends along a (straight) longitudinal axis 32 from a first longitudinal rod end 33 to a second longitudinal rod end 34. The threaded rod 5 is attached with its first longitudinal rod end 33 to a plate-shaped wall element 4.
[0098] The rotary ring 10 is in an open position 11 in Fig. 4. In the open position 11, the threaded sleeve 6 with its receptacle 7 can be inserted parallel to the longitudinal axis 8 onto the second longitudinal end 34 of the threaded rod 5, and / or the threaded rod 5 with its second longitudinal end 34 can be moved parallel to the longitudinal axis 8 in the receptacle 7. The open position 11 of the rotary ring 10 allows a coarse adjustment of the distance 35 shown in Fig. 2 between the mounting frame 21 and the wall 23, also shown in Fig. 2.
[0099] Fig. 5 shows the wall mounting device 1 with the rotating ring 10 in the open position 11 in a sectional view along a first section plane 36 shown in Fig. 4, looking towards the first longitudinal end 29 of the threaded sleeve 6. In the open position 11, the rotating ring 10 releases the threaded rod 5, so that the threaded rod 5 can be moved in the receptacle 7 parallel to the longitudinal axis 8 at a distance 38 from the thread root 9. This allows the threaded rod 5 to be moved in the receptacle 7 for coarse adjustment of the distance 35 shown in Fig. 2.
[0100] Fig. 6 shows the wall mounting device 1 with the rotary ring 10 in a sectional view along the first section plane 36 shown in Fig. 4, after the rotary ring 10 (after completion of the coarse adjustment of the distance 35 shown in Fig. 2) has been rotated from the open position 11 shown in Fig. 5 by an angle of rotation 39 about the longitudinal axis 8 to a closed position 12. The angle of rotation 39 between the closed position 12 shown in Fig. 5 and the open position 11 is, by way of example, 90°. The rotary ring 10 has a ramp 41 on its inner circumferential surface 40, which presses the threaded rod 5 into the thread root 9 of the receptacle 7 via the clamping element 17 when the rotary ring 10 is rotated into the closed position 12. The rotary ring 10 holds the threaded rod 5 in the thread root 9 of the receptacle 7 as long as the rotary ring 10 is in the Grohe AG

[0103] The locking ring 10 is in the closed position 12. The clamping element 17 is adjustable orthogonally to the longitudinal axis 8 (in the direction of the thread root 9) via the ramp 41. In the closed position 12 of the locking ring 10, an external thread 42 of the threaded rod 5 engages with the thread root 9 or the partial thread 13. When the threaded rod 5 engages with the thread root 9 and / or the locking ring 10 is in the closed position 12, the threaded rod 5 is not freely movable in the receptacle 7 parallel to the longitudinal axis 8.
[0104] In a next step, the wall element 4 of the wall mounting device 1, shown in Fig. 4, can be attached to the wall 23 shown in Figs. 1 and 2. The attachment can be made, for example, using at least one screw (not shown here). Subsequently, the threaded sleeve 6 can be rotated about the longitudinal axis 8 via the drive geometry 16 shown in Fig. 3, whereby the threaded rod 5 can be adjusted parallel to the longitudinal axis 8 in the receptacle 7 via the thread root 9 or via the partial thread 13 for fine adjustment of the distance 35 shown in Fig. 2.
[0105] The clamping element 17 has a retaining rib 43 and, adjacent to the retaining rib 43, two spring bars 44. The retaining rib 43 forms a stop for the threaded rod 5. The spring bars 44 are elastically designed and can press the threaded rod 5 into the thread root 9 without play.
[0106] Fig. 7 shows the wall mounting device 1 with the rotating ring 10 in the closed position 12 in a perspective view. The rotating ring 10 has a locking hook 45 which engages in a groove 46 of the threaded sleeve 6 in the closed position 12. This prevents the rotating ring 10 from unintentionally rotating out of the closed position 12. The locking hook 45 can be released from the groove 46 by means of a lever 47 on the rotating ring 10. The rotating ring 10 has snap hooks 48 with which the rotating ring 10 is attached to the second guide flange 15 of the threaded sleeve 6. This prevents the rotating ring 10 from detaching from the threaded sleeve 6 along the longitudinal axis 8 in the direction of the first longitudinal end 29 of the threaded sleeve 6. Grohe AG

[0114] Fig. 10 shows the wall mounting device 1 with the mounting section 18 of the threaded sleeve 6 in the mounting opening 31 of the mounting frame 21 of the installation element 2 in a sectional view along the second section plane 37 shown in Fig. 4 (parallel to the longitudinal axis 8). The mounting section 18 has a first flange 64, a second flange 65, and a third flange 66. The first flange 64 is formed at the second longitudinal end 30 of the threaded sleeve 6. The wall mounting device 1 is inserted into the mounting opening 31 with the mounting section 18 such that a mounting frame wall 67 of the mounting frame 21 (parallel to the longitudinal axis 8) is located between the first flange 64 and the second flange 65.The fastening clamp 20 is placed with its legs 49 onto the fastening section 18 of the threaded sleeve 6 in such a way that the fastening clamp 20 is located between the first flange 64 and the mounting frame wall 67.
[0115] The clamping ring 19 is attached to the third flange 66 by its mounting hooks 63 and is supported at its first longitudinal end 57 against the mounting frame wall 67. The clamping ring 19 is resiliently mounted on the third flange 66 parallel to the longitudinal axis 8 by the spring tabs 60 (for example, with a spring travel of approximately 1 mm). The spring travel is limited in the direction of the first longitudinal end 29 of the threaded sleeve 6 shown in Fig. 3 by the stops 59 and in the direction of the second longitudinal end 30 of the threaded sleeve 6 by the mounting hooks 63. The spring tabs 60 press the clamping ring 19 towards the second longitudinal end 30 of the threaded sleeve 6 against the mounting frame 21 or against the mounting frame wall 67. The clamping ring 19 allows the mounting section 18 to be easily inserted into the mounting opening 31.The clamping ring 19 also compensates for manufacturing tolerances, so that the wall mounting device 1 can be attached to the mounting frame 21 without play.
[0116] The invention enables the installation element 2 to be mounted on the wall 23 with minimal effort. Grohe AG
