Description

The invention relates to a device for fastening a cover to a washstand having the features of the preamble of claim 1.

From the publication WO 2008/083781 A1 a device is known with which a cover can be attached to a washstand. The cover, which is usually made of ceramic, serves to make the washbasin visually appealing in the area of the siphon. The attachment is made to two threaded bolts, which also serve to attach the washstand to the wall. At each threaded bolt a receiving element is attached, which holds a drawstring in a curved receiving channel. The drawstring has a screening and the receiving element on a latching tongue in the manner of a cable tie. With one end, the drawstring is suspended in a wall opening of the cover. The mounting of the cover is done by the receiving elements attached to the threaded bolt and the drawstring is suspended in the cover. Then the drawstrings are pulled at the other ends, so that the cover is raised in the direction of the washstand. The locking of the drawstring in the receiving element causes a backup, so that the cover does not move down again. The cover is pulled up until it touches the bottom of the washstand.

The problem is the release of such a device. This may be necessary on the one hand in case of disassembly of the cover. On the other hand, a loosening of the device but even during assembly may be required if the cover is tilted and tilted. Although the document fails WO 2008/083781 A1 prior to equip the drawstring and the receiving element with the function of a Mehrwegkabelbinders and thus to make solvable, but the operation is complex. Namely, the locking tongue must be solved, which is experience with a washstand with limited accessibility and limited light conditions only with great skill possible. Above all, however, causes the release of the locking tongue that the drawstring suddenly completely solved becomes, which leads to at least a one-sided fall of the cover, if not the destruction of the cover.

The invention is therefore based on the object to provide a device for attaching a cover to a washstand with improved assembly and disassembly properties.

This object is achieved by the features of claim 1. The device according to the invention has a base body, on which a first suspension element for attachment to a load-receiving device is arranged. The load-receiving device is arranged on the washstand side, although this does not mean that it must be arranged on the washstand itself. It can also be arranged, for example, on the wall itself. It is crucial that the tensile load for lifting the cover in the direction of the washbasin can be removed. The load receiving device is in particular a threaded rod, which can also serve to attach the washstand to a wall. However, the load-receiving device may also be, for example, a projection or the like on the washstand itself. The first suspension element can be, for example, a hook or an eyelet, which can be inserted via a bolt-like load-receiving device. However, the first suspension element can also be, for example, a screw or a nut. The decisive factor is a connection to the load receiving device.

The device furthermore has a tension band which connects a second suspension element to the base body in a length-adjustable manner. The length adjustability refers to the free length of the tension band between the second suspension element and the base body. The second hanging element is used for attachment to the cover. As far as the shape of the second hooking element is concerned, the statements relating to the first hooking element apply accordingly.

According to the invention, the drawstring has a toothing which engages with an adjusting screw of the main body. The drawstring with toothing resembles a rack, wherein the band is not rigid, but preferably flexible except in the longitudinal direction. By a rotation of the adjusting screw, there is a relative movement of adjusting screw to drawstring, whereby the distance of the first to the second hooking element is adjustable. By such an arrangement, both the lifting and the lowering of the cover by a simple rotational movement possible. The adjusting screw and the toothing of the drawstring are preferably designed so that they are self-locking, so that the adjusting screw must not be secured by further measures against accidental rotation. In this way, the assembly and disassembly is greatly facilitated, and there is no risk that the drawstring is suddenly released.

Preferably, the base body has a housing of two housing halves, wherein the housing halves are connected by at least one film hinge. This allows the production as an injection molded part and ensures a simple error-free installation. On the one hand, the adjusting screw can be mounted between the two housing halves and, on the other hand, the tension band can be inserted before closing the two housing halves.

In order to achieve a good mobility of the device during lifting as well as a flexible adaptation to a wide variety of geometries of washbasins and covers, the invention proposes that the first suspension element has an eyelet and a bearing on a load-receiving bearing sleeve. Eyelet and bearing sleeve are designed such that the base body is held about two axes pivotally to the load-receiving device. Compared to a fixed clamping, this has the advantage that no additional deformation forces are introduced into the device. For example, in a threaded rod anchored in a wall as a load-receiving device, the base body on the one hand about the longitudinal axis of the threaded rod and on the other hand away from the wall pivotally.

Alternatively, the first hooking element can be connected to the main body via a second film hinge, so that at least the pivotability about an axis relative to the load receiving device is made possible by the film hinge. The pivotability about a further axis is then carried out by the attachment of the suspension element, so that the base body is held about two axes pivotally to the load-receiving device.

In order to provide a simple connection to a threaded rod as a load-receiving device that does not require additional components such as nuts, the invention proposes that the first suspension element has a locking device for connection to a threaded rod. The first suspension element can be easily pushed over the threaded rod and is again by the latching device Loosen secured. In this case, the latching device, for example, either be designed so that it can be solved only by larger forces or by rotation or by using tools or even by small forces. In the latter case, the latch only serves a temporary backup, which is supplemented by a nut or the like.

Preferably, the adjusting screw on a hammer head. This allows the rotation by hand at relatively small dimensions. Alternatively or additionally, a tool approach can be provided.

If the tension band is loosened, in particular when disassembling the cover, there is a risk that the operator will turn the adjusting screw until the toothing is disengaged and the tension band is released from the base body. The invention therefore has a stop which prevents loosening of the drawstring from the main body when the adjusting screw is turned too far. This avoids that the drawstring comes off suddenly, which could lead to a fall of the cover.

In the sense of a simple assembly, the invention also proposes that the drawstring has a snap device, with which it can be fastened secured to a fastening bolt or the like, wherein the fastening bolt is arranged on the cover. In this way, the drawstring can be hung or otherwise fastened to the fastening bolt, and the snapping-in of the snap-in device prevents the connection from coming loose, in particular as long as the tensioning strap still hangs loose.

The invention will be illustrated below with reference to an embodiment and a variant in the region of the first hooking element.

In the FIGS. 1 and 2 in each case a section of the underside of a washbasin 1 is shown, wherein for the sake of clarity, no siphon is shown. For visual enhancement, a hood-shaped, upwardly open cover 2 is attached from below. With the help of two devices 3 according to the invention it is pulled up against the washstand 1 and held permanently in this state. Shown is a state with only partially pulled up cover. 2

The device 3 consists of a base body 4, which in turn consists essentially of a flat housing 5 made of plastic. Formed on the housing 5 is integrally an eyelet 6, which is part of a first hooking element 7 of the device 3. On the details of the first Einhängeelements 7 is based FIG. 5 discussed in more detail. With the hooking element 7, the base body 4 is fastened to a threaded rod 8 as a washstand-side load-receiving device 9. The threaded rod 8 is anchored in a wall (not shown) and also holds the washstand. 1

From the main body 4 protrudes down a tension band 10 made of plastic, which has a transverse side teeth 11 on a flat side. The drawstring 10 extends into the cover 2 and along the inside 12 along. At the cover-side end, the drawstring 10 in one piece has a second hooking element 13 in the form of a hook 14. In a circular recess the cover 2, a fastening bolt 15 is mounted, which projects into the interior of the cover 2 and in which the hook 14 is mounted. This will be explained below FIG. 6 discussed in more detail.

Figures 3 and 4 show the main body 4, the tension band 10 and the two suspension elements 7, 13, wherein FIG. 4 the components during a manufacturer's pre-assembly and FIG. 3 shows the completely pre-assembled state. The housing 5 of the main body 4 consists of two housing halves 16, which are connected by a first film hinge 17 in the form of two thin, easily bendable webs 18. The two housing halves 16 are sprayed next to one another, so that the housing inner sides 20 point in the same direction in the case of both housing halves 16. To form a channel 21 for guiding the tension band 10, both housing halves 16 have mutually corresponding walls 22. The channel 21 extends arcuately, so that the drawstring 10, which is inserted in the context of the pre-assembly in the channel 21, with both ends pointing obliquely downwards. Adjacent to the channel 21, an adjusting screw 23 is arranged with a trapezoidal thread 24 in the housing halves 16, in such a way that the trapezoidal thread 24 of the adjusting screw 23 meshes with the toothing 11 of the tension band 10. For mounting the adjusting screw 23, the housing halves 16 each have two half-shell-shaped bearing points 25. After inserting the tension band 10 and the adjusting screw 23, the housing 5 is closed, that is, one of the two housing halves 16 is turned by 180 ° and connected via clip connections with the other housing half 16.

The adjusting screw 23 has a hammer head 26 for manual operation and a transverse slot 27 for actuation with a tool. The trapezoidal thread 24 and the hammer head 26 are dimensioned so that a few turns to lift the cover 2 suffice, but this is still easily possible even with heavy ceramic covers by hand. Furthermore, the trapezoidal thread 24 is dimensioned so that it acts self-locking, so it does not come to an unwanted twisting or adjustment by train on the tension band 10.

So that when pulling the cover 2 from the housing 5 exiting drawstring 10 does not get too close to the hammer head 26 of the adjusting screw 23 and disturbs when turning, the channel 21 at the adjusting screw 23 facing the exit point of the tension band 10 has a deflector 28 in the form of a tight curve. Upon exiting the drawstring 10, this is the deflector 28 of the adjusting screw 23 away directed. In order that the drawstring 10 does not accidentally come out of the housing 5 in the direction of the hook 14, it has at its end facing the adjusting screw 23 a rectangular extension 29 which does not fit through the channel 21. The extension 29 thus serves as a stop 30, so that a release of the tension band 10 is prevented by the base body 4 by rotation of the adjusting screw 23.

In FIG. 5 the first suspension element 7 is shown in more detail. In addition to the eyelet 6 belongs to the suspension element 7, a bearing sleeve 31 which is screwed with an internal thread 49 on the threaded rod 8. The bearing sleeve 31 is screwed against a nut 32, which secures the washstand 1 on the threaded rod 8. The outer contour of the bearing sleeve 31 initially widens conically away from the nut 32 and forms a support 33 for the eyelet 6 in this area. An operating flange 34 with a knurling 35 adjoins the support 33 at its circumference. Because the support 33 is significantly wider than the eyelet 6, it can be tilted very easily on the support 33. The main body 4 can thus be pivoted about an axis perpendicular to the image plane axis (shown in phantom). In addition, eyelet 6 and bearing sleeve 31 serve as a pivot bearing, so that the base body 4 can also be pivoted about the longitudinal axis of the threaded rod 8. The effect of this pivoting that the body 4 can align according to the geometric conditions of the vanity 1 and cover 2 and the prevailing forces.

FIG. 6 shows the region of the second hooking element 13. In the wall of the cover 2 (dashed lines), a circular recess 36 is provided, through which the fastening bolt 15 protrudes. The fastening bolt 15 terminates externally with a flange 37 and adheres to the inside 12 of the cover 2 with two radially elastic hook elements 38. From there, a shank 39 of the fastening bolt 15 widens conically. This causes the hook 14 is automatically moved in lifting the cover 2 in the direction of the inner side 12 and does not threaten to slip from the mounting bolt 15. In order to prevent slipping down immediately after the hook 14 has been hooked into the fastening bolt 15, the hook 14 has an elastic tongue 40, which closes a receptacle 41 of the hook 14 for the fastening bolt 15 and presses it into the receptacle when the fastening bolt 15 is inserted can be. The tongue 40 forms a snap device 42 for securing the connection between the fastening bolt 15 and tension band 10.

In the FIGS. 7 and 8 an alternative embodiment of the first hooking element 7 'is shown. Instead of an eyelet 6, the hooking element 7 'has a bushing 43, which can be pushed onto the threaded rod 8 like the eyelet 6. The bushing 43 corresponds in its inner diameter substantially the threaded rod 8. By its length, the bushing 42 is thus not tilted on the threaded rod 8. The double pivoting of the base body 4 'relative to the threaded rod 8 is achieved in this embodiment by a connection of the housing 5 via a second film hinge 44, wherein the second film hinge 44 is dimensioned stronger due to the considerable forces than usual film hinges. The inner circumference of the sleeve 43 is widened at three evenly spaced locations by grooves 45. Within the grooves 45 each radially standing latching tongues 46 are arranged, which engage in the thread 47 of the threaded rod 8. The locking tongues 46 form a latching device 48, which secures the bushing 43 against unintentional release of the threaded rod 8. Compared to the first embodiment can be omitted in this way a component, namely the bearing sleeve 31. The entire first suspension part 7 'is thus part of the main body 4'.
