Description

The invention relates to a device, such as a shower enclosure, according to the preamble of claim 1, a fitting according to the preamble of claim 16 and a disc according to the preamble of claim 24.

Flush fittings for glass, in which, for example, a countersunk screw engages in a countersunk hole in the disc and bolted to a fitting, have long been known, for example from DE 77 05 090 TJ1. So far, the counterbores are always performed at an inclination of 45 °. The screw heads or conical holding elements have always had a corresponding inclination. In practice, it has been shown that no optimal resilient connection between the disc and fitting can be achieved.

The present invention has for its object to provide a device, in particular a shower enclosure, a fitting and a disc for a shower enclosure, which allow a very durable and therefore durable connection of a particular glass existing disc with a fitting.

The above object is achieved by a device according to claim 1, a fitting according to claim 16 or a disc according to claim 24. Advantageous developments are subject of the dependent claims,

One aspect of the present invention is to provide a much smaller angle of inclination than 45 ° to the plane of the disc for the inclined or conical section or counterbore in the disc. This leads to strained conditions to better load conditions. As a result, a surprisingly stronger load-bearing connection between the disc and the fitting can be achieved.

Another, independently realizable aspect of the present invention is to incline the inclined or conical portion of a holding element engaging in the recess of the disc stronger than the inclined or conical portion of the recess in the disc. A correspondingly adapted intermediate element that is arranged between the holding element and the recess and consists of a relative to the holding element and the disc softer material is then thinner in the region of greater thickness of the disc or with increasing radial distance from the center of the holding element or the recess and / or more heavily loaded, whereby a better load distribution with surprisingly significantly improved load capacity of the connection is achieved. In particular, the surface pressure of the intermediate element in the installed state is radially outward at least constant or increases compared to the prior art.

Instead of or in addition to the different inclination of the preferably conical portion of the retaining element relative to the counterbore in the disc, this section may also be stepped, stepped or otherwise modified on the retaining element in order to obtain a comparable effect. In the limiting case, the second inclination angle, ie the inclination angle of this section on the holding part, even be 0 ° and support the holding element via the correspondingly adapted intermediate element on the inclined or conical portion of the recess in the disc.

According to a particularly preferred embodiment, which can be realized in particular in combination with the preferred, compared to the prior art lower angle of inclination of the inclined or conical portion of Ausneh = tion in the disc, the disc has starting from both flat sides correspondingly inclined or conical sections or depressions on the recess, so that the fitting is selectively attachable to one of the two flat sides of the disc. This allows a universal use of the prefabricated disc. In particular, for example, either right-sided or left-sided attacks of doors or structures of shower enclosures can be made with the same parts.

In the following, the device according to the proposal will be further explained on the particularly preferred example of a shower enclosure. However, it can be the device but also to a partition, door, cladding, facade, in particular for buildings, a railing or the like act. The following statements apply accordingly.

In the figures, the same reference numerals are used for the same or similar parts, and corresponding features and advantages are achieved, even if a repeated description is omitted for the sake of simplicity.

Fig. 1 shows a detail of a proposed device in the form of a shower enclosure 1 with at least one disc 2, in the illustrated example, two discs 2, and an associated fitting 3. The fitting. 3 is here designed as a hinge and connects the two discs 2, but the fitting 3 can alternatively serve only a rigid connection of the two discs 2 or only the holder of a disc 2, for example, for a wall-side attachment or the like.

In the illustrated example, the fitting 3 is for example a compound of a fixed disc 2 with a pivotable door glass 3. The two hinge halves or hinge lugs (fittings) of the fitting 3 are preferably connected in a corresponding manner with the respective associated disc 2. However, this is not mandatory; Different connections can also be provided. Hereinafter, the present invention will be explained in detail with reference to such a compound.

FIG. 2 shows in an enlarged detail of FIG. 1 such a connection of the fitting 3 or a fitting part with an associated pane 2. The pane 2 is preferably made of glass, in particular single-pane safety glass, or another suitable, preferably transparent material.

The disc 2 has an opening or recess 4 with a first, inclined or conical section 5 with a first inclination angle α to the disc plane E. The recess 4 is, in particular, a bore, wherein the first section 5 is formed by countersinking from a flat side, that is to say around a counterbore.

In the illustrated embodiment, the recess 4 is formed with the section 5 rotationally symmetrical to the preferably perpendicular to the disk plane E extending center axis M. In the following, this rotational symmetry is always assumed. However, in principle, a non-rotationally symmetrical design of the recess 4 and / or the section 5 may be provided. The following remarks and explanations then apply at least accordingly.

The fitting 3 has an engaging in the recess 4, preferably metallic holding element 6. The holding element 6 is adapted to the recess 4 and in particular the first section 5. It has a second, inclined or conical portion 7 with a second inclination angle β to the disc plane E, as shown in FIG. 2 and the sectional view of FIG. 7 can be seen. In particular, the holding element 6 is at least substantially rotationally symmetrical, wherein the axis of rotation runs in the installed or mounted state at least substantially along the center line M of the recess 4. The holding part 6 is preferably integrally formed, in particular as a cast or turned part.

Between the holding element 6 and the recess 4 or, the disc 2 - at least in the region between the two sections 5 and 7 - an intermediate element 8 is preferably arranged, in particular from a respect to the material of the disc 2 and the material of the holding member 6 softer or deformable material, preferably plastic. The intermediate element 8 prevents an excessive point load of the glass, in particular in the case of a glass pane 2.

Fig. 3 shows in a sectional view in the illustration with respect to the center line M rotationally symmetrical intermediate element 8 with a doppelkonischen ring section 9 and a subsequent sleeve section 10. The detail of FIG. 4 of Fig. 3 illustrates the conical design of the ring portion 9. This will be explained later discussed in more detail.

5 shows the retaining element 6 in a perspective front view. 6 shows the retaining element 6 in a perspective rear view. Fig. 7 shows a section of the holding element 6.

In the exemplary embodiment, the holding element 6 has a collar 11 which, on its rear side facing the fitting 3, forms the second section 7, that is to say the section 7 conical in the illustration. This is followed by an at least substantially cylindrical portion 12, which fits into the recess 4 and the sleeve portion 10.

The holding element 6 preferably forms an abutment, in particular in the form of a bore or - as in the illustration example - in the form of a slot 13, for a screw 14 or other connection element for connection with the fitting 3 or fitting part, as indicated in FIGS. 1 and 2. In the illustrated example, the holding element 6 forms a recess for receiving the head of the screw 14. At the bottom of the recess, the slot 13 is arranged. The slot 13 serves here an adjustability of the support member 6 relative to the screw 14 and thus also relative to the fitting 3. The screw 14 is in fact screwed into the fitting 3 or the associated fitting or otherwise firmly connected with this in the other state.

Irn dissolved state, so when not tightened screw 14, or during assembly, the support member 6 can be inserted in a suitable rotational position in the recess 4 and connected by means of the screw 14 with the fitting 3 and an adjustment of the fitting 3 relative to the recess. 4 respectively.

When tightened, the screw 14 biases the retaining element 6 against the fitting 3 or the associated fitting element, the retaining element 6 engages behind the section 5 of the recess 4 with its section 7 and clamps the disc 2 against the fitting 3 or respectively via the intermediate element 8 The assigned fitting part.

According to an alternative embodiment, not shown, the retaining element 6 itself as a screw 14, in particular in the form of a countersunk screw, be formed. The fitting 3 facing bottom of the head then forms the second, preferably inclined or conical section 7. The disadvantage here is that the two-part design and the slot 13 made possible adjustability is not given.

In order to prevent damage to the disc 2, in particular by an excessive punctiform load, an intermediate layer 15 of a suitable, in particular elastic or rubber-like material is preferably arranged between the fitting part and the disc 2, as indicated in Fig. 2.

In order to prevent rotation of the support member 6 relative to the fitting 3 and in particular a special rotationally fixed connection between the To allow disk 2 and the fitting 3, the holding element 6 at least one projection or - as in the illustration - at least one threaded hole 16 for a grub screw 17 or other screw for rotationally secure securing or clamping of the support member 6 on the fitting 3.

The engaging in the recess 4 holding element 6 and the intermediate element 8 are executed at least substantially flat on the side facing away from the fitting 3 flat side of the disc 2. In order to prevent contamination, to achieve a particularly smooth or flush termination and / or to allow an overall aesthetic impression, a cover 18 is preferably additionally arranged on the flat side facing away from the fitting 3, as indicated in Fig. 2. The cover 18 is here, for example, disk-shaped or cap-like, smoothly closes off with the flat side of the disk 2 and preferably has locking elements 19 for engagement in adapted recesses 20 of the retaining element 6

Experiments have shown that, in particular with the measures or ratios described below, a surprisingly high-strength connection of the disc 2 with the fitting 3 can be achieved.

The first inclination angle α is preferably greater, in particular by at least 3 °, particularly preferably by approximately 5 ° or more, than the second inclination angle β. Compared to the usual tendency so far results in a - at least compared to the prior art - higher surface pressure of the intermediate element 8 and on the portion 5 of the disc 2 with increasing distance from the center line M and, from the center of the holding element 6. Accordingly with increasing radial distance, the thickness of the intermediate element 8 and its annular portion 9 from.

Preferably, the intermediate element 8 or its annular portion 9 is adapted to the different angles of inclination α and β. In the illustrated example, the intermediate element 8 or its annular section 9 has a first contact surface 21 facing the first section 5 and a second contact surface 22 facing the second section 7, as indicated in FIG. 4. The first contact surface 21 is preferably at least substantially inclined to the disc plane E at the first inclination angle α. The second contact surface 22 is preferably at least substantially inclined at the second inclination angle β to the disk plane E, so fits the cross-section preferably at least substantially wedge-shaped annular portion 9 of the intermediate element 8 over the entire surface between the first section 5 and the second section. 7

According to an alternative or additional measure, the two angles of inclination α and β are preferably at most 40 °, in particular at most 35 °, very preferably approximately 30 ° or less. This compared to the prior art low or flat inclination leads to a tendency to higher pressure load of the glass 2 and a lower shear stress of the intermediate element 8. This has an advantageous effect on the load capacity of the compound, as experiments have surprisingly clearly shown.

In the illustrated example, the first inclination angle α is about 30 ° and the second inclination angle β is about 25 °.

The inclined or conical section 5 of the recess 4 preferably extends over at least 30%, in particular about 40% or more, of the thickness of the disk 2. Thus, a large contact surface for the retaining element 6 is formed even at a low inclination angle α.

According to a particularly preferred embodiment, the disc 2, starting from both flat sides in each case an inclined or conical section 5, as shown in the sectional view of FIG. 9. In particular, the recess 4 is therefore countersunk starting from both flat sides.

In Fig. 9 different variants are shown on the right and on the left side. In both variants, with regard to the inclination angle α, in particular the values already mentioned apply.

In the embodiment variant shown on the left side, the recess 4 has an at least substantially trapezoidal side wall in a section perpendicular to the plane of the pane E, in which case the sections 5 too the side wall are counted. Alternatively, the side wall may also be substantially triangular.

In the embodiment variant shown on the right-hand side in FIG. 9, the side wall is substantially parabolic or rounded in the region of the smallest radius of the recess 4. As a result, excessive stresses, especially in the region of edges can be avoided.

It should be noted that the inclination of the first portion 5 and / or the inclination of the second portion 7 may vary depending on the radius and the distance to the center line M, respectively. In particular, the inclination towards the center line M may increase. Accordingly, the above statements regarding the preferred values for the inclination angles α and β apply in particular to the annular regions of the sections 5 and 7 immediately adjacent to the flat sides of the disc 2, even if the inclination then increases towards the center.

Conversely or in addition, the inclined section 5 can also flow smoothly or rounded-that is, with decreasing inclination-into the adjoining flat side of the pane 2.

The design of the recess 4 shown in Fig. 9 with inclined or conical sections 5, starting from both flat sides of the disc 2, ie with double-sided reduction, allows a particularly universal use of the proposed disc 2, since the associated fitting 3 either on one of the two Flat sides can be mounted as needed. Accordingly, the disc 2 can be used more universally than with only one-sided attachment possibility of the fitting 3.
