DEVICE FOR MOUNTING A SANITARY FITTING

Description

[0001] The present invention relates to a device for attaching a sanitary fitting to a support. Sanitary fittings serve in particular to provide liquid as needed at a washbasin, sink, kitchen sink, bathtub and / or shower.

[0002] Fastening devices for sanitary fittings have become known from documents CN 203247651 U, CN 103243782 A, CN 109024782 A, US 2016 / 0258142 A1, and EP 3 048 206 A1. A sanitary fitting is typically fastened by means of a threaded rod rigidly attached to the fitting. The fitting is placed on the support, for example, a washbasin, sink, basin, bathtub, shower, and / or a worktop, over a mounting opening in the support or a tap hole, with the threaded rod being inserted through the tap hole. A mounting plate is slid onto the threaded rod to secure the fitting and is fastened to the rod with a fixing nut. Tightening the fixing nut clamps the fitting to the support.During installation, the plumbing fixture must be held firmly on the support by hand to prevent it from tipping over during installation, which could damage the support and / or the plumbing fixture. At the same time, the fastening nut must be screwed onto the threaded rod below the support, which can be difficult due to limited space and poor visibility below the support.

[0003] 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 device with which a sanitary fitting can be attached and / or detached with minimal effort.

[0004] This object is achieved with a device according to the features of the independent patent claim. Further advantageous embodiments of the invention are specified in the dependent patent claims. It should be noted that the features listed in the dependent patent claims define further embodiments of the invention. Furthermore, the features specified in the patent claims are further specified and explained in the description, with further preferred embodiments of the invention being presented.

[0005] This is aided by a device for attaching a sanitary fitting to a support, which has at least the following features: a base; a guide rod attached to the base with a stop formed on the guide rod, wherein the guide rod has a first guide area with a straight course and a second guide area with a course that is at least partially curved; a drive rod attached to the base; and a clamping element which is adjustable along the guide rod by the drive rod and pivotable into a release position by the stop of the guide rod.

[0006] The sanitary fitting serves, for example, to provide a liquid, in particular water, to a vanity unit, kitchen sink, wash basin, shower, and / or bathtub. The sanitary fitting can have a fitting housing, which is preferably made at least partially of plastic and / or (cast) metal, such as brass. The fitting housing can have an outlet that is rigidly or movably attached to the fitting housing, in particular pivotably and / or at least partially extendably. The fitting housing and / or the outlet can have at least one outlet opening for the liquid. The liquid can be released, in particular, into the environment of the sanitary fitting via the at least one outlet opening. Furthermore, the sanitary fitting can comprise a mixing valve for mixing cold water and hot water to form mixed water with a desired mixed water temperature. The mixing valve is arranged, in particular, in the fitting housing.The cold water can be supplied to the mixing valve, in particular, via a cold water pipe, and the hot water via a hot water pipe. The cold water can have a cold water temperature that is, in particular, a maximum of 25 °C (Celsius), preferably 1 °C to 25 °C, particularly preferably 5 °C to 20 °C. The hot water can have a hot water temperature that is, in particular, a maximum of 90 °C, preferably 25 °C to 90 °C, particularly preferably 55 °C to 65 °C.

[0007] The device allows the sanitary fitting to be attached to a support, such as a vanity unit, washbasin, sink, bathtub, shower, and / or countertop. For this purpose, the support can have a mounting opening into and / or onto which the device can be inserted. The mounting opening can, for example, have a diameter of 25 mm (millimeters) to 45 mm, preferably 30 mm to 37 mm.

[0008] The device comprises a base, which may be made at least partially of plastic and / or metal, such as brass or stainless steel. The base may be at least partially tubular and / or ring-shaped. This allows the cold water pipe and / or hot water pipe to be easily routed through the base. The base may extend along a longitudinal axis, which is particularly straight. The longitudinal axis of the base runs, in particular, through its center. The base may have a contact surface, particularly on an end face, with which the base rests on the top of the support when the device is mounted. A seal, particularly ring-shaped, may be arranged on the contact surface to seal any gap between the base and the support, preventing liquid from passing through. The base may have a centering contour that allows the base to be centered on the mounting opening of the support.This can mean, for example, that the base can be aligned coaxially to the mounting opening of the support via the centering contour.

[0009] A guide rod is attached to the base, in particular rigidly. This can mean, in particular, that the guide rod is not movable relative to the base. The guide rod extends, in particular, along a longitudinal guide rod axis, in particular an at least partially straight one. The longitudinal guide rod axis can run at least partially parallel to the longitudinal axis of the base and / or at a distance (in particular orthogonal) from the longitudinal axis of the base. The guide rod can have a length of at least 50 mm, preferably 50 mm to 200 mm, in particular starting from the base or the contact surface of the base. The guide rod length is measured, in particular, parallel to the longitudinal axis of the base. In addition, the guide rod can have a diameter of, for example, 2 mm to 20 mm, in particular orthogonal to the longitudinal axis of the base.Furthermore, the guide rod can be made at least partially of plastic and / or metal, such as stainless steel. The guide rod can also have a smooth circumferential surface. The guide rod also features a stop. This stop can, for example, extend at least partially perpendicular to the longitudinal axis of the base, the longitudinal axis of the guide rod, and / or the longitudinal axis of the drive rod. Additionally, the stop can be at least partially cylindrical.

[0010] The device further comprises a drive rod. The drive rod can, for example, be designed in the manner of a threaded rod and / or be fastened to the base so as to be rotatable about a drive rod longitudinal axis. This can mean, in particular, that the drive rod is rotatable relative to the base about the drive rod longitudinal axis. For this purpose, the base can have a receptacle and / or guide for the drive rod. The drive rod can extend along a, in particular straight, drive rod longitudinal axis. The drive rod longitudinal axis extends, in particular, parallel to the base longitudinal axis and / or guide rod longitudinal axis. Furthermore, the drive rod longitudinal axis can have a distance from the base longitudinal axis and / or guide rod longitudinal axis, in particular a distance that is orthogonal to the base longitudinal axis. The drive rod can thus extend eccentrically to the base. The drive rod can, in particular starting from the base orthe contact surface of the base, have a drive rod length of at least 70 mm, preferably 70 mm to 220 mm.

[0011] In addition, the device comprises a clamping element, which is guided in particular by the guide rod. For example, the clamping element can be connected to the guide rod via a plain bearing. The clamping element can be made at least partially of plastic and / or metal, such as stainless steel or cast material. In addition, the clamping element can be designed in the manner of a stamped part and / or bent part. Furthermore, the clamping element is adjustable by the drive rod along the guide rod, the guide rod longitudinal axis, the drive rod, the drive rod longitudinal axis and / or the base longitudinal axis. For this purpose, the drive rod can extend in particular through a threaded bore of the clamping element, so that an external thread of the drive rod engages with an internal thread of the threaded bore. The clamping element is thus adjustable in particular by rotating the drive rod about the drive rod longitudinal axis.The guide rod prevents the clamping element from twisting. By adjusting the clamping element, the distance between the clamping element and the base or the base's contact surface can be changed. This allows the distance between the contact surface and the base to be changed during assembly of the device such that the support can be clamped between the clamping element and the base.

[0012] The clamping element is designed such that it can be inserted through the mounting opening of the support, along with the guide rod and / or the drive rod. Furthermore, the clamping element can be designed such that, after the device is centered in and / or on the mounting opening of the support, it overlaps a lower surface of the support in the direction of the longitudinal axis of the base and / or the longitudinal axis of the guide rod. For this purpose, the clamping element can extend radially from the guide rod and / or drive rod. The radial direction is, in particular, orthogonal to the longitudinal axis of the base, the longitudinal axis of the drive rod, and / or the longitudinal axis of the guide rod. Furthermore, the clamping element can have a cross-section that is at least partially round, oval, quadrilateral, and / or rectangular, particularly orthogonal to the longitudinal axis of the base, the longitudinal axis of the drive rod, and / or the longitudinal axis of the guide rod.The clamping element can extend from the drive rod in the radial direction, for example with a clamping element length of 10 mm to 50 mm, preferably 10 mm to 40 mm.

[0013] The clamping element can be pivoted into a release position by the stop of the guide rod. For this purpose, the clamping element can rest on the stop with a stop surface when the clamping element is moved away from the base with the drive rod. In the release position, the clamping element does not cover the mounting opening of the support, so that the device or the clamping element can be moved through the mounting opening, in particular parallel to a mounting opening longitudinal axis of the mounting opening, the base longitudinal axis, the guide rod longitudinal axis, and / or the drive rod longitudinal axis.

[0014] Since the clamping element is already connected to the base, there is no need to attach a mounting plate to a threaded rod and secure it with a nut during installation, thus reducing assembly time. Furthermore, the drive rod can be rotated during mounting of the device to the support, particularly from above or from the top of the support, allowing the device or sanitary fitting to be attached to the support from above. Therefore, attaching the device or sanitary fitting does not have to be a complicated and / or difficult task requiring tools from below the support. Likewise, the device or sanitary fitting can be removed from above the support.

[0015] The base can have a fastening section to which the sanitary fitting can be fastened. The fastening section can be at least partially tubular, annular, rectangular, hexagonal and / or polygonal. Furthermore, the fastening section can extend upwards from the base (when the device is assembled). In addition, the fastening section can run coaxially to the longitudinal axis of the base. The sanitary fitting or the fitting housing of the sanitary fitting can in particular be plugged onto the fastening section and / or fastened to the fastening section with a fastening means, for example in the manner of at least one screw, a thread, a spring, a pressure piece and / or a bayonet lock.

[0016] The clamping element can have a pivot axis about which it is pivotably attached to the drive rod. For this purpose, the clamping element can have a swivel joint. The swivel joint can, for example, include an axis that extends through at least one axle bearing of the clamping element.

[0017] The clamping element can be pivoted into a fastening position by a return spring. For this purpose, the return spring can be tensioned, for example, when the clamping element is pivoted into the release position. The clamping element can be pivoted into the fastening position by the return spring, in particular when the clamping element is moved away from the stop or towards the base by the drive rod. In the fastening position, the carrier can be clamped in particular between the base and the clamping element, whereas in the release position the carrier cannot be clamped between the base and the clamping element. In particular, the clamping element can be aligned at least partially orthogonal to the drive rod longitudinal axis, guide rod longitudinal axis, base longitudinal axis and / or mounting opening longitudinal axis in the fastening position.In the fastening position, the clamping element can cover the mounting opening of the carrier so that the clamping element cannot be moved through the mounting opening from the top side of the carrier. Furthermore, in the fastening position, a clamping surface of the clamping element can be brought into contact with an underside of the carrier. Furthermore, in the release position, the clamping element can be tilted relative to the fastening position so that the clamping element is oriented in particular obliquely to the drive rod longitudinal axis, guide rod longitudinal axis, base longitudinal axis and / or mounting opening longitudinal axis. The clamping element can be pivoted about the pivot axis between the release position and the fastening position, for example with a pivot angle of 60° to 90°.

[0018] The return spring can be designed like a torsion spring.

[0019] The clamping element can, in particular, be made at least partially of sheet metal. In particular, the clamping element can be made at least partially of sheet metal. The sheet metal can have a thickness of, for example, 1 mm to 10 mm. In particular, the clamping element can be designed at least partially in the manner of a bent sheet metal component.

[0020] The stop can be arranged at a longitudinal end of the guide rod. This allows the longitudinal end of the guide rod to be T-shaped, for example. In particular, the stop can be arranged at a longitudinal end of the guide rod opposite the base.

[0021] The drive rod can have a drive geometry for engaging a tool. The drive geometry can be, for example, an external hexagon, internal hexagon, internal Torx, external Torx, Torx, and / or spline drive. The tool can be, for example, a wrench or an Allen key. The drive geometry can be located at a longitudinal end of the threaded rod. In particular, the drive geometry can be located at an upper longitudinal end of the threaded rod and / or at a longitudinal end of the threaded rod facing the base.

[0022] The guide rod can extend through an elongated hole in the clamping element. In particular, the guide rod and the drive rod can extend through the elongated hole. The elongated hole can, in particular, be designed in the manner of an elongated bore or groove. The width of the elongated hole can (essentially) correspond to a diameter of the guide rod.

[0023] According to the invention, the guide rod has a first guide region with a straight profile and a second guide region with an at least partially curved profile. In the first guide region, the guide rod extends in particular parallel to the base longitudinal axis, the mounting opening longitudinal axis, and / or the drive rod longitudinal axis. The first guide region can have a first guide region length of, for example, at least 30 mm, preferably 30 mm to 150 mm, parallel to the base longitudinal axis, the mounting opening longitudinal axis, and / or the drive rod longitudinal axis. The second guide region or the guide rod longitudinal axis can be at least partially C-shaped in the second guide region.In the second guide region, the guide rod can have a first arc with a first angle of, for example, 10° to 20°, preferably (essentially) 15°, a second arc with a second angle of 160° to 170°, preferably (essentially) 165°, and / or a third angle of 160° to 170°, preferably (essentially) 165°. A region between the second arc and the third arc of the guide rod can run parallel to the base longitudinal axis, mounting opening longitudinal axis, and / or drive rod longitudinal axis. In addition, the second guide region and / or the region between the second arc and the third arc can have an offset from the first guide region of the guide rod in the direction of the drive rod. The offset can be, for example, 1 mm to 20 mm, preferably 1 mm to 5 mm, particularly preferably (essentially) 3 mm.This allows the clamping element to be pivoted from the fastening position to the release position with a larger angle of rotation.

[0024] The invention and its technical context are explained in more detail below with reference to the figures. It should be noted that the figures show a particularly preferred embodiment of the invention, but that the invention is not limited to this embodiment. Identical components in the figures are designated with the same reference numerals. The figures show, by way of example and schematically: Fig. 1: a device in a first side view; Fig. 2: the device in a perspective view; Fig. 3: the device in a second side view; Fig. 4: a guide rod of the device in a perspective view; Fig. 5: the guide rod in a side view; Fig. 6: an axis of a clamping element of the device in a perspective view; and Fig. 7: the clamping element in a perspective view.

[0025] The Fig. 1 shows a device 1 fastened to a carrier 3 in a first side view. The carrier 3 has a mounting opening 20 into which the device 1 has been inserted from a top side 21 of the carrier 3. The device 1 comprises a base 4 with a fastening section 10, on which a Fig. 1 only partially shown sanitary fitting 2. The base 4 is ring-shaped or sleeve-shaped and extends along a base longitudinal axis 19. A drive rod 7 for a tensioning element 8 is fastened to the base 4. The drive rod 7 is designed in the manner of a threaded rod and is fastened to the base 4 about a drive rod longitudinal axis 22 of the drive rod 7 relative to the base 4. The drive rod longitudinal axis 22 and the drive rod 7 have a straight course. Furthermore, the device 1 has a guide rod 5 for the tensioning element 8. The guide rod 5 is firmly attached to the base 4, so that the guide rod 5 is not movable relative to the base 4. In addition, the guide rod 5 extends through a Fig. 7 The clamping element 8 has a slot 16 shown and a stop 6 for the clamping element 8 at a first longitudinal end 14. The guide rod 5 is attached to the base 4 at a second longitudinal end 24 opposite the first longitudinal end 14. By rotating the drive rod 7 about its longitudinal axis 22, a clamping element 8 can be adjusted along the drive rod 7, or parallel to its longitudinal axis 22, in a vertical direction 23. Fig. 1 The clamping element 8 is adjusted towards the base 4 so that a clamping surface 25 of the clamping element 8 contacts a bottom surface 26 of the support 3. This secures or clamps the device 1 to the support 3. Furthermore, the clamping element 8 is located in the Fig. 1 in a fastening position 13, in which the clamping element 8 or the clamping surface 25 of the clamping element 8 is aligned orthogonally to the longitudinal axis 22 of the drive rod. In fastening position 13, the clamping element 8 covers the mounting opening 20 of the support 3, so that the clamping element 8 cannot be pulled out through the mounting opening 20 from the top 21 of the support 3.

[0026] The Fig. 2 Figure 1 shows the device in a perspective view looking into an interior space 27 of the base 4. It can be seen in the Fig. 2 Among other things, the guide rod 5 is attached to the base 4 by a fastening element 28, which in this case is a screw. Furthermore, the drive rod 7 has a drive geometry 15 for a tool (not shown here), by means of which the drive rod 7 can be rotated about its longitudinal axis 22. The drive geometry 15 is designed in the form of an internal hexagon socket.

[0027] The Fig. 3 shows the device 1 in a second side view, after the clamping element 8 has been completely clamped to a clamping element arranged in the Fig. 1 visible third longitudinal end 29 of the drive rod 7 was adjusted. The drive rod 7 is rotatably attached to the base 4 with a fourth longitudinal end 30 opposite the third longitudinal end 29. When adjusting the clamping element 8 in the direction of the third longitudinal end 29 of the drive rod 7, the clamping element 8 has a stop surface 31 opposite the clamping surface 25 on the stop 6 of the guide rod 5, so that the clamping element 8 from the Fig. 1 shown fastening position 13 clockwise about a pivot axis 11 into a release position 9. For this purpose, the clamping element 8 is connected to the drive axle 7 via a pivot joint 42. The pivot joint 42 comprises an axle 43, which is supported in a first axle bearing 44 and a Fig. 3 not visible second axle bearing 45 of the clamping element 8. The pivot axis 11 runs in the Fig. 3 perpendicular to the drawing plane. In the release position 9, the clamping element 8 does not cover the mounting opening 20, so that the device 1 or the clamping element 8 can be pulled out of the mounting opening 20 in the direction of the upper side 21 of the carrier 3.

[0028] The Fig. 4 Figure 1 shows the guide rod 5 in a perspective view. The stop 6 at the third longitudinal end 29 of the guide rod 5 is cylindrical and extends along a stop longitudinal axis 32. The stop longitudinal axis 32 runs orthogonally to the one shown in the Fig. 3 shown drive rod longitudinal axis 22. The guide rod 5 is thus T-shaped in the area of ​​the stop 6.

[0029] The Fig. 5 Figure 1 shows the guide rod 5 in a side view. The guide rod 5 has a first guide section 17 with a straight path and a second guide section 18 with a curved path. The first guide section 17 extends from the second longitudinal end 24 parallel to the path shown in the Fig. 3 The longitudinal axis 22 of the drive rod 7 shown extends to the second guide section 18 with a first guide section length 33. The second guide section 18 extends from the first guide section 17 to the first longitudinal end 14 with a second guide section length 34. The first guide section length 33 and the second guide section length 34 are parallel to the axis shown in the Fig. 3 The longitudinal axis 22 of the drive rod 7 is shown. The second guide section 18 of the guide rod 5 has a first arc 35 with a first angle 38, a second arc 36 with a second angle 39, and a third arc 37 with a third angle 40. A section between the second arc 36 and the third arc 37 of the guide rod 5 runs parallel to the longitudinal axis 22 of the drive rod 7. Fig. 3 shown drive rod longitudinal axis 22. In addition, this area has an offset 41 to the first guide area 17 of the guide rod 5 in the direction of the Fig. 3 shown drive rod 7. This allows the clamping element 8 to be rotated with a larger angle from the position shown in the Fig. 1 shown fastening position 13 into the position shown in the Fig. 3 shown release position 9 pivotable.

[0030] The Fig. 6 shows the axis 43 of the Fig. 1 and 3 shown swivel joint 42 at the third longitudinal end 29 of the drive rod 7. The drive rod 7 extends through a threaded bore 46 of the axle 43, so that an external thread of the drive rod 7 engages with an internal thread of the threaded bore 46. On an outer circumferential surface 47 of the axle 43, a return spring 12 is arranged, by means of which the tensioning element 8 is moved from the position shown in the Fig. 3 shown release position 9 when adjusting the clamping element 8 in the direction of the base 4 around the pivot axis 11 in the Fig. 1 shown fastening position 13. The return spring 12 is designed in the manner of a torsion spring. Furthermore, the return spring 12 comprises a wound wire 48 with an outer wire end 49 and a (in the Fig. 6 not visible) inner wire end. The inner wire end of the return spring 12 is arranged in a groove 50 of the axis 43, so that the return spring 12 cannot be rotated or cannot be fully rotated about the axis 43 or the pivot axis 11. When pivoting the clamping element 8 from the position shown in the Fig. 1 shown fastening position 13 into the position shown in the Fig. 3 shown release position 9, the outer wire end 49 is bent by the tensioning element 8 and the return spring 12 is thereby tensioned.

[0031] In the Fig. 7 The clamping element 8 is shown in a perspective view. The clamping element 8 comprises the first axle bearing 44 and second axle bearing 45 for the Fig. 6 axis 43 shown in the Fig. 3 The pivot joint 42 shown. The first axle bearing 44 and second axle bearing 45 are formed in the manner of bores in a bent sheet of the clamping element 8, so that the clamping element 8 can pivot about the pivot axis 11. Furthermore, in the Fig. 7 the slot 16 of the clamping element 8 is visible, through which the Fig. 1 and 3 shown guide rod 5 and drive rod 7. The clamping element 8 is bent such that the clamping surface 25 is opposite the stop surface 31.

[0032] By means of the present invention, the sanitary fitting 2 can be attached to and detached from the support 3 with little effort. Bezugszeichenliste
