Description

The invention relates to a device, such as a shower enclosure, with a disc and an associated fitting.

Flush fittings for glass, in which, for example, a countersunk screw engages in a counterbore in the disc and bolted to a fitting, have long been known, for example from DE 77 05 090 U1 , So far, the counterbores are always carried out in an inclination of 45 °, the screw heads or conical holding elements have always had a corresponding inclination. In practice, it has been found that no optimal loadable connection between the disc and fitting can be achieved in this way,

The EP 0 801 201 A1 relates to a system for mounting a glass sheet with a structural element and a connecting part, such as a screw. The disc has at least one flat side a bore with a countersink and is connectable to the structural element by means of the connecting part. A portion of the connecting part is adapted to a conical surface of the counterbore, wherein the opening angle of the cone of the connecting part is greater than the cone of the counterbore of 45 ° and wherein the half cone angle can be different from each other by 0.5 ° to 5 °. Furthermore, a metallic sealing element between the connecting part and the countersunk hole is arranged.

The DE 43 40 509 A1 understood a holding device for facade and roof panels, especially glass. A suspension part is attached to a glass sheet by means of a threaded bolt which passes through a through hole of the disk and on which a threaded nut is screwed attached. The through hole of the disc is provided with a conical depression, which has an inclination angle of about 30 ° to the disc plane. The nut is designed to be complementary, with an intermediate element being arranged between nut and glass pane.

The WO 03/033848 A2 discloses a fastening device for glass panes. The disc has a conical-bore through bore into which a two-piece through-hole insert and a cylinder head screw are inserted to secure the disc to a fitting or profile. Between the bore of the insert and the outer thread diameter and the Sehaftdurchmesser the screw game is provided so that the cylinder head screw can perform a relative movement to the glass and the insert.

The DE 203 02 389 U1 concerns a fitting and a shower enclosure. A disc has a through-bore with a first conical Abschwitzt, wherein the reduction has a first inclination angle to the disc plane. The fitting has a holding element engaging in the bore with a second conical section, wherein the section has a second angle of inclination to the disk plane. Between the holding element and the disc, an intermediate element is arranged, wherein the thickness of the intermediate element between the two sections, starting from the center of the holding element decreases towards the outside.

The DE 202 000 37 U1 discloses a hinge fitting for glass doors. The glass door has a conical bore for attachment to a support disc. The conical bore receives a corresponding conically shaped clamping insert. A screw passes through the clamping insert and is screwed into the carrier disc. A cover cap can be clipped into the clamping insert and covers the screw and the clamping insert.

The present invention has for its object the known system of EP 0 801 201 educate, so that a simple and cost-effective design a very durable and therefore durable connection of a particular glass existing disc is made possible with a fitting.

The above object is achieved by a device according to claim 1. Advantageous developments are the 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 portion 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 aspect of the present invention is to incline the inclined or conical portion of a retaining 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.

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 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 section of Fig. 1 Such a connection of the fitting 3 or a fitting part with an associated disc 2. The disc 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 disk plane E on how Fig. 2 and the sectional view according to 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 formed in one piece, in particular as a cast or rotary 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 arranged, in particular from a respect to the material of the disc 2 and the material of the holding element 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 representation example 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 according to Fig. 4 from Fig. 3 illustrates the conical design of the ring section 9. This will be discussed later in more detail.

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

In the illustrated example, the holding element 6 has a collar 11 which forms on its rear side facing the fitting 3 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 shell 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 in Fig. 1 and 2 indicated. 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 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 excessive punctiform loading, 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 in FIG Fig. 2 indicated.

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 soiling, 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 in Fig. 2 indicated. 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 greater, in particular by at least 3 °, particularly preferably by about 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 middle of the holding element 6. Accordingly, takes with increasing radial distance, the thickness of the intermediate element 8 and its annular portion 9 from.

The intermediate element 8 or its annular section 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 in FIG Fig. 4 indicated. The first contact surface 21 is at least substantially at the first inclination angle α to the disk plane E inclined. The second contact surface 22 is shown at least substantially at the second inclination angle β to the disk plane E, so fits the cross-section 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 additional measure, the two inclination angles α and β are at most 35 °, more preferably about 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 portion 5 of the recess 4 preferably extends over at least 30%, in particular about 44% or more, of the thickness of the disc 2. Thus, even at a low inclination angle α, a large contact surface for the retaining element 6 is formed,

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

In Fig. 9 are shown on the right and on the left side different variants. 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.

At the on the right in Fig. 9 the embodiment shown, the side wall is formed 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.

In the Fig. 9 shown embodiment of the recess 4 with inclined or conical sections 5, starting from two 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 optionally mounted on one of the two flat sides as needed can be. Accordingly, the disc 2 can be used more universally than with only one-sided attachment possibility of the fitting 3.
