Abstract

The invention concerns a fixing device for flat materials, in particular glass panes (16), which are fixed by force-closure and form-closure to profiled sections, angle sections, mobile strips, hinges or fittings. Therefor, it consists in producing in the glass pane (6) a through hole (18) in the form of a tapered hole (18, 19) or a stepped hole (23, 24). The tapered hole (18, 19) or the stepped hole (23, 24) houses an insert (5, 21, 22, 10, 28, 31) wherein is inserted a through screw, in particular a screw with cylindrical head (3) or a screw with truncated head, with a clearance all around to enable the glass pane to be adjusted before being fixed by force-closure.

Description

Title: Fastener

description

The invention relates to a fastening device for flat materials, which is to be understood in particular as glass panes which are non-positively fastened to profiles, mounting brackets, movable bands or hinges or fitting parts, etc. The flat materials have a through hole with a countersink, into which a fastening screw is inserted in order to, for. B. to attach a sheet of glass. Fastening devices of this type are used, in particular for glass partitions and / or shower partitions.

Such a fastening option can be found in German utility model DE 75 16 780 U1. A countersunk hole is provided within a glass pane of a fixed side part, into which a connecting screw engages. A fitting is attached to the opposite glass surface using the connecting screw. Due to the countersunk screw, there is no fitting part or fastening part on the glass surface opposite the fitting, so that the glass surface is easy to clean. In addition, the movable side part of the shower can also be placed closer to the fixed side part, which at the same time offers better sealing options against splash and splash water due to the smaller distance. The disadvantage of this attachment is, however, that due to the tolerances existing on the building, a tolerance compensation of the fixed side part to the fitting is not possible.

The object of the invention is to provide a fastening device for flat materials, in particular glass panes, which is inexpensive. inexpensive to manufacture, easy to assemble and also adjustable and a good possibility to clean the surfaces, e.g. B. glass panes.

The object is achieved by the characterizing features of claims 1 and 5 in conjunction with the preamble features. The subclaims represent a further embodiment of the inventive idea.

In a first embodiment, a form-fitting insert piece is used in a countersunk bore within a glass pane, which has a step-shaped through-bore. A cylinder screw is inserted into the stepped through hole as a fastening means. Both the shaft of the cheese head screw and the head are embedded within the insert so that they have play in relation to the insert. The fact that there is a corresponding game around the threaded shaft and the cylinder head, z. B. the glass pane to be attached perform a relative movement and thus adjustment before attachment. This type of adjustment is usually sufficient to e.g. B. Shower screens can be easily installed with both their fixed side panels and movable wings.

A contact surface is present within the through bore, against which a lower contact surface of the cylinder head comes to rest. In a further embodiment, it is also possible to produce the insert from two parts, the first part being positively fitted in the countersunk hole in the glass pane and the second part being inserted positively in a countersunk hole provided in the first part. Such an approach can e.g. This can be useful, for example, if the first part is made from a different material than the second part of the insert. This can be the case in particular if the first part is a softer material as glass protection than that of the second part.

In a further preferred embodiment, a step-shaped through-hole can be present within an insert, which is also immersed in a counterbore in the glass pane. In this case, the use of a fastening screw as a cylinder head screw is dispensed with and a countersunk screw is used for fastening. The head of the countersunk screw is embedded within an intermediate piece that has a through hole with a countersink according to the degree of inclination of the head of the countersunk screw. -The intermediate piece has an outer smooth contour and lies within the step-shaped through hole. There is also a clearance between the outer contour of the intermediate piece, which is cylindrical, and the step-shaped through-bore, which is so large that the glass pane can be adjusted before the force-fitting fastening.

In a further embodiment, instead of the counterbore, a step-shaped through-hole with different diameters can be made inside the glass pane. Appropriate insert pieces, which have a corresponding complementary shape to the stepped bore, are then used here.

Such inserts and the intermediate piece described above can, for. B. made of plastic, aluminum, brass or stainless steel. In order to enable a design-related adaptation to the other fitting parts, the insert pieces or the intermediate piece can be chrome-plated or painted. So that there is a smooth surface without depressions in relation to the glass pane surface, it is possible according to the invention to close the insert pieces with a closure. It has proven to be advantageous to use a thin pane as the closure, which is flush with the glass surface.

The invention is explained in more detail with reference to various exemplary embodiments which are shown schematically in the drawings.

It shows:

In the following explanations, it is always assumed that a glass pane 16 is used as the flat material. However, it goes without saying that in addition to a glass pane, all other flat materials such as plastic, wood or metal can also be fastened in an adjustable manner using the fastening device according to the invention.

A first exemplary embodiment of a fastening device has been shown in an exploded perspective view in FIG. A glass pane 16 has not been shown. A first part 1 of an insert 5, which has a cylindrical part 11, to which a conical part, which is not described in more detail, connects, can be used within the bore (not shown), which is designed as a counterbore. A through bore 14 is located within the cylindrical part 11. The conical part adjoins the cylindrical part 11 with a counterbore 25. The second part, which is designated by 2, is inserted within the counterbore 25. The part 2 also has a cylindrical bore 15, which is present within a cylindrical region, which is not described in detail. This cylindrical part 2 engages in the cylindrical part 11, at least partially, of the through hole 14. Otherwise, the outer shape of the second part 2 can be seen as a complementary shape to the counterbore 25. Within part 2 there is a contact surface 13 against which a cylinder head screw 3 with a contact surface 7 comes to rest. At the same time, part 2 with the cylinder head screw 3 located therein can be closed by a washer (lock).

The assembled part of the fastening device can be seen in Figure 2. The first part 1, which with the second part 2 piece 5 reproduces, is inside the glass pane, not shown, with both the cylindrical part 11 and the conical part 12. How the

Figure 2 can be clearly seen, the cylinder head screw 3 has a

- Threaded shaft 6, which can be screwed in for fastening to a substructure, a profile, a bracket on the movable belt or fitting parts. Furthermore, the cylinder head screw 3 consists of a cylinder head 27 in which a tool attachment 10, for. B. in the form of a hexagon socket. On the basis of the illustration in FIG. 2, it is clear that there is play 8 on all sides between the threaded shaft 6 and the through bore 15 within the second part 2. An equal size game 9 is present in the area of the cylinder head 27. Thus, after use of the insert 5, the cylinder head screw 3 can perform a relative movement due to the games 8 and 9 with respect to the substructure or the fitting part and the glass pane 16. The fastening device is closed by the disk 4.

FIG. 3 shows a further exemplary embodiment of a fastening device in which, in contrast to the first exemplary embodiment, a countersunk screw 17 is used. The second part 2 is again inserted into the first part 1, but in this case it is designed such that it an intermediate piece 20, which consists of a cylindrical part with a countersink, can accommodate. The head of a countersunk screw can be received within the countersink. The intermediate piece 20 has a lateral play 9 with the second part 2, the threaded shaft of the countersunk screw 17 also having a play 8 with respect to a through hole within the insert piece 21. Here, too, the fastening device is closed by a disk 4.

In a further exemplary embodiment, which is shown in FIG. 4, a modification compared to FIG. 3 can be seen in that instead of parts 1 and 2 only one insert 21 is used. This insert 21 has a cylindrical extension which dips into the cylindrical part 18 of a through hole within the glass pane 16, a conical region of the insert 21 nestling against a countersink 19 adjoining the cylindrical holes 18. As in FIG. 3, an insert 20 is inserted within the insert 21, which comes to rest on a contact surface within the insert 21. There is also play 8 opposite the shaft of the countersunk screw 17, the head of the countersunk screw 17 being embedded within the conical course of the bore within the intermediate piece 20. It is also clear from this illustration of FIG. 4 that, in addition to the game 8 for the threaded shaft of the countersunk screw 17, there is also a game 9 with respect to the intermediate piece 20. The countersunk screw 17 can thus also perform a relative movement with respect to the glass pane 16 within the cylindrical bore 18.

A further modified embodiment can be seen in FIG. 5 compared to FIG. 4. Within the glass pane 16 there is a stepped bore 23, 24, in which an insert 22 adapted to this stepped bore 23, 24 is embedded. Within the insert 22, the structure with the previously described intermediate piece 20 has been carried out analogously. This countersunk screw can therefore also perform a relative movement within the bore 23 within the glass pane 16.

A further exemplary embodiment is shown in FIG. 6, in which, in contrast to FIG. 1, an integral insert 28 is used. This insert 28 has a cylindrical part to which a conical part is attached. The insert piece 28 has a stepped bore 29, 30, into which the cylinder head screw 3 with its head 27 inside the stepped bore 30 and its shaft inside the stepped bore 29 surfaced. Here, too, there is play 8 with respect to the shaft of the cylinder head screw 3 as well as play 9 with respect to the cylinder head 27, so that the already described relative movement of the cylinder head screw 3 with respect to the stepped bore 29, 30 is possible.

The cylinder head screw 3 used in FIG. 6 and FIG. 1 or FIG. 2 has been shown separately again in FIG. 7.

Another exemplary embodiment of a fastening device is shown in FIG. 8, in which, in contrast to FIG. 6, there is a stepped bore 23, 24 inside the glass pane 16. An insert 31 with a corresponding complementary shape is inserted into the stepped bore 23, 24. Here, too, the cylinder head screw 3 has corresponding play 8 and 9, in order to thus ensure an adjustment of the glass pane 16 during assembly.

The present description is not to be regarded as conclusive, rather the equivalents of the above-described fastening device, not shown, are also relevant to the invention and are therefore to be seen under the claims of this invention.
