The rotation-adjustable retaining element (2, 27) are used as fittings or fitting parts in the glass panes flush-closed with a surface area of glass panes, inserted in cascade drilled hole.

Description

The invention relates to a fitting for fixing glass panes, which consist of fixed side parts and sliding or rotating doors. In this case, the glass panes are connected to one another and for connection to walls adjustable flush mounted in the glass panes holding elements on hinges or angles or the like non-positively and positively. For adjustability of the glass sheets is located in the holding piece Druchgangsbohrung a lying eccentrically to the center of the holding element and is penetrated by a connecting screw. On both sides, the use of a tool for rotating the retaining element and thus for adjustment is present on the outside of the retaining element.

The EP 0 841 032 A2 discloses a device which is used for holding and fixing of glass panes on shower cubicles or doors use. In this case, an adjustment element which is rotatable to the angle or hinge used is proposed for adjusting the plates or glass panes to be fastened. The adjusting element has an eccentric part in relation to the axis of the fastening element, which makes it possible by rotation between the glass and the wall to make an adjustment. In this case, a holding part is used, which has a bore and an annular shoulder has formed, against which a clamping screw applies. A turntable sits in a cylindrical arrangement and has lateral stops in the form of protrusions. The attacks are provided on its outer side in the region of the projections with a thread for the application of a cap. To achieve a rotatability is located in the turntable a slot. Due to the eccentricity of the connecting screw to be introduced is moved by turning the turntable and a sliding block, which is secured against rotation but slidable in the longitudinal direction, the holding part with the glass. This does not appear executable because turning the turntable without With the help of a tool is not possible and because the hub has an external thread.

The object of the present invention is to be seen to achieve a simple adjustability of fittings in glass with a concealed inconspicuous appearance of fittings, especially in terms of a good cleaning ability of the glass over on one of its outer surface.

The invention is solved by the teaching according to the patent claim 1, wherein the dependent claims reproduce a further embodiment of the inventive concept.

It is therefore proposed to better clean the glass panes no protruding fittings or caps to use, but rather to perform a sinking of this otherwise usually resting fittings within the glass panes both in the fixed glass panes as well as the sliding doors or revolving doors. For this purpose, in addition to the usual holes for fastening beyond the sink holes are introduced in the glass panes, which may have both a conical shape but also be realized in the form of a gradation. Due to the fact that no fitting parts protrude and the fittings located within the holes with their sinks are flush with the upper edge of the glass sheets, cleaning can be carried out without problems.

In order to achieve an adjustability for tolerance compensation or for adaptation to the environment of the side parts and the wings, mechanisms are also provided, which make it possible to continuously variable adjustment with respect to the given by manufacturing and structural tolerances deviations.

In the holes of the glass panes holding elements are used for this, which have a bore with respect to its center, which is arranged eccentrically to the center. In this case, the bore of the Hatteelementes preferably has a countersink to accommodate a connecting screw or a connecting element can. Following the countersink for the connecting screw there is a through hole without a thread.

In order to fasten a glass pane to a fitting part, first the holding element is inserted inside the bore of the glass pane and then guided through the eccentric bore within the holding element, the connecting screw. The connecting screw can be connected on the other side of the glass with a fitting in the form of a hinge, bracket or a suspension. To adjust the glass pane relative to a stationary wall or another glass pane in the form of a fixed side part, a rotation of the retaining element about its center can be effected via existing on the surface of the holding element adjustment options, for example in the form of two spaced holes or recessed Allen. The fact that the connecting screw is not centric, thus a stepless adjustment and thus adjustment of the glass to the left / right or up / down is possible. It is understood that this can also be done in fittings larger type, where, for example, within a hinge lobe two or three connecting screws are attached.

In a second embodiment, which is not part of the invention, a slot is present within the retaining element. The effect of the elongated hole is the same as in the eccentric hole, only finer settings of the glass are possible.

The hole in the glass pane can be made both as a stepped stepped bore and as a conical countersink with subsequent cylindrical part. The retaining element always has a complementary shape.

In fitting technology, it is customary to insert an intermediate layer between fittings and glass. This liner serves to prevent damage to the glass.

For simplicity and to reduce costs, these liners or inserts have not been used in the proposed holding elements. For this, the retaining element consists of a plastic having the necessary strength. For this purpose, preferably a plastic with a glass fiber insert can be used. By using the plastic, the holding elements can be inexpensively manufactured by injection molding.

In order to hide the connecting screw and the adjusting mechanisms of the holding elements, they can be covered with a disc or cap to be stuck.

By this type of attachment, a cost-effective way to connect fitting / glass has been created, since only a small number of components for fixing a glass sheet is needed. This manifests itself in particular in the design of the retaining element. A holding element of the aforementioned type can thus be combined with different fitting parts.

In the FIG. 1 is shown in a sectional view, a holding element 2. The holding element 2 shows a cylindrical projection 9, which merges into a conical profile 8. However, it is also possible to use a cylindrical shoulder instead of the tapered course 8. With respect to a central axis 25 of the retaining element 2 is eccentrically to a bore 6 provided, which is provided with a countersink 5. In the plan view of the holding element 2 shows the FIG. 2 Beyond adjusting bores 7 for approach of a tool to rotate the support member 2 about its central axis 25. It is clear that by the rotation of the holding element 2 about its central axis 25, the bore 6 descends a circular course. However, since the holding member 2 is not attached to its central axis 25, but via the bore 6, as will be described below, the support member 2 does not rotate about its central axis 25 but about the central axis of the bore. 6

Another type of adjustment and thus an approach to a tool show the FIGS. 3 and 4 in which the holding element 2 has on its upper side a recess in the form of a large hexagon socket 22 in which a corresponding tool with complementary shape can be used for adjustment.

The execution of FIG. 2 a shows the adjustment of the retaining element via an adjustment 26 in the form of a small hexagon socket, which is dimensionally adjusted so that an Allen wrench can be used.

In the FIG. 5 a further embodiment of a retaining element 27 is reproduced, which is not part of the invention. This holding element includes in its center a slot 28 which is provided with a countersink 29. Through this slot 28 is a very fine adjustment of the glass sheet 1 in conjunction with a fixed-mounted band by rotation of the holding element 27 via the adjusting holes 7 possible. The holding member 27 is in the FIG. 6 reproduced in a sectional view through the arrangement of the elongated hole 28 beyond. By lowering 29, the connecting screw 3, without protruding insert within the slot. However, it is also possible to provide here instead of the counterbore 29 a stepped bore and use a cylinder head bolt to use the connecting screw 3.

Both the holding element 2 and the holding member 27 may be outwardly by a cover 30, which in the FIG. 7 is reproduced, closed. On the cover 30, pins 31 are formed, which can engage, for example, in the adjusting holes 7 of the holding elements 2 and 27. However, it is also conceivable to carry out the cover 30 without the molded pins 31; In this case, the cover 30 would be adhered to the holding elements 2, 27 by means of a suitable adhesive.

According to the invention, only the reproduction of the holding element 2 is shown in the following embodiments.

The above-described holding element 2 is in the following descriptions of FIGS. 9-13 within a hinge with its hinge tabs 10, 11 are used. It is understood that the application for connection to hinge lugs of a hinge is not exhaustive, but also may be given in brackets, brackets, etc. use.

The holding member 2 is used in addition to the adjustment for fixing a glass sheet 1, as it FIG. 9 reproduces. Within the glass pane 1, the holding element 2 of the type described above is used. There is an intermediate layer 12 between the hinge tabs 10 and the glass pane 1. The holding element 2, which is located within the unspecified hole within the glass pane 1, is penetrated by a connecting screw 3. At the same time the connecting screw 3 is screwed within a threaded bore 13 which is located in the hinge lugs 10. Thus, a simple attachment of a glass sheet 1 on a hinge tab 10 is possible. At the same time, a flush surface is provided on the side facing away from the hinge flap 10 of the glass pane 1, in order to effect a correspondingly good cleaning capability of such glass panes. The hinge can be pivoted about an axis of rotation 19, wherein the second hinge lobe 11 can be attached to a wall 24 in an analogous manner. The position of the holding element 2 in the FIG. 9 is to be referred to as the center position, thus resulting in a mean distance 23 to a wall 24 of the glass pane 1 from. In the FIG. 10 the retaining element 2 has been rotated via the adjusting holes 7 in such a way that a larger distance 23 to the wall 24 results. In the FIG. 11 on the other hand, the minimum distance 23 to the wall 24 is reproduced. In addition, the embodiment of the FIG. 11 a different kind of attachment of the connecting screw 3 relative to the hinge lobes 10. Within the hinge lobe 10 is no threaded hole, but a through hole 14 is present. Through the connecting screw 3, which is inserted through the holding element 2 with its bore 6 and the through hole 14, by fastening a nut 15, an attachment of the glass pane 1 relative to the hinge lobe 10 can be effected.

The FIG. 12 are the most varied adjustment options with respect to the bore 6 within the retaining element 2 again. It can be effected by the corresponding rotation within the hinge lobes 10, 11 on the one hand, an upper position 16 of the glass, in contrast, of course, a lower position 20, also a right position 17 and a left position 21. The greater the eccentricity of Bore 6 to the central axis 25 of the retaining element 2, the greater is the adjustment range.

In the FIG. 13 are in the hinge lobes 11 two connecting screws 3 and in the hinge lugs 10, a connecting screw 3 is screwed within threaded inserts 4. These threaded inserts 4, for example, in the production within the hinge lobes 10, 11 are positively and positively secured. Through the corresponding rotation of the holding elements 2, an adjustment of the glass pane 1 to a glass pane 18 or to the wall, not shown, is thus possible.

By using the threaded inserts z. B. the fittings are made of the same plastic, as the holding elements. In such a case, for. B. the intermediate layer 12 between the hinge lugs 10, 11 and the glass panes 1, 18 accounts.
