Description

The invention relates according to the preamble of claim 1, a device for fastening sheet-like elements, in particular glass plates, to a support structure, with a holding element, which can be fastened to the support structure and engageable with the sheet-like element.

Generic fasteners are marketed by the applicant for a long time in different embodiments and with different design principles for attachment. For fastening a glass pane between two supporting structures four fastening devices are generally used, two of which are each arranged on the opposite end faces of the glass plate and fixed by means of fastening devices on the glass plate. Glass panels attached to supporting structures are often found in public buildings such as underground shafts, railings of shopping centers, bridges, etc. In particular, in the open air, for example, by wind loads comparatively high forces acting transversely to the plane of the plate on the glass. In addition, lateral forces can be caused transversely to the glass plate also by not suitable holes within the glass plate or by impact load as a result of intentional or unwanted shocks against the glass plate.

The loads acting on the glass plate cause damage, which occur in particular in the vicinity of the fastening device. The glass plates must therefore be made of a suitable composite material or shatterproof glass and have a sufficient thickness, depending on the installation location of the glass plate.

Generic clamp holders therefore have two disadvantages: Firstly, it is necessary to make penetrations through the glass pane receiving points, on the other hand they are often only cumbersome and very difficult to attach to the sheet-like element (glass plate).

At one off DE 93 10 973.3 Known embodiment, a first attempt to reduce the stresses within the glass plate is already undertaken, in which the holder forms a right angle with its bottom and its front side, wherein each two opposite corners are rounded and a recess is shaped so that it forms a claw Recording of sheet-like elements forms.

The problem with the embodiment shown here, however, is that the fastening device is not adaptable to different installation situations and glass geometries. An adaptation of the glass to the fastening devices must therefore be made. Furthermore, angle corrections of the glass pane relative to the supporting structure are not possible because there is no displacement or twistability. This makes assembly very difficult. Furthermore, no permanent and visually aesthetic attachment is guaranteed.

It is therefore an object of the invention to provide a fastening device for fastening sheet-like elements, in which the above-mentioned disadvantages are avoided. Furthermore, an easier assembly should be given and can be adapted to different glass geometries and manufacturing tolerances, the fastening device. Furthermore, no tensions are to be placed in the sheet-like element to be used and it should be avoided that a recess or mounting hole is required in the sheet-like element.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 15.

A device for fastening sheet-like elements to a support structure, comprising a holding element, which can be fastened to a supporting structure and brought into engagement with the sheet-like element, provides that the holding element has a receiving element for the sheet-like element, which can be inserted into a base body, wherein the base body is attached to the support structure.

The advantage here is that during assembly first of the base body can be attached to the support structure. The receiving element is attached to the sheet-like element. As a result, it is possible for the person skilled in the art to prepare the heavy sheet-like element (for example a glass plate) to such an extent that the actual assembly, together with the lifting operation, is considerably simplified. For that no penetrations by the sheet-like element are necessary. Compressive stresses can thus be distributed within the receiving element and thus relieve the sheet-like element in the corner areas.

It is particularly advantageous if the retaining element has a recess for the sheet-like element and the surface element can be inserted and / or clamped into the recess.

This makes it possible for the fitter at the installation site to fasten and align the entire fastening device to the supporting structure. Subsequently, the sheet-like element can be inserted from above into the holding element. Thus, the glass plate is already firmly attached to the support structure and no longer needs to be supported by the installer or a helper. The entire assembly is considerably simplified.

A further embodiment of the invention provides that the recess for the sheet-like element is formed as a groove which is open on one side and is arranged in the longitudinal direction of the receiving element.

The groove thus formed offers the advantage in the device according to the invention that the mounting handles can continue to be considerably simplified, since the sheet-like element can find an abutment at any point of the recess. If the groove is only open on one side, the holding element with its support element can also form a backup in the longitudinal direction.

Particularly advantageous is the embodiment of the invention such that the base body receives the receiving element axially displaceable.

This allows the regulation of the distances from the main body to the sheet-like element and also offers the possibility to set up as the first assembly step, the holding element on the sheet-like element and then insert it into the body.

An additional advantage is obtained when the main body while the receiving element force, form and / or frictionally receives. In particular, when the receiving element has a first coupling means that can be brought into engagement with the base body, a positive and / or non-positive connection between the receiving element and the base body is ensured.

A further embodiment of the invention provides that the base body provides a second coupling means for receiving the first coupling means. This significantly improves the durability and ease of installation at the installation site. Preferably, the coupling means are formed as a rotationally symmetrical plate with collar or as associated recordings to these. The plate with collar then slides securely into the associated receptacle and thus prevents slipping and decentering of the body to the receiving element.

Moreover, it is advantageous if the holding element and the base body are rotatable relative to one another. This offers advantages in mounting at the installation site. Thus, for example, the lower edge of a sheet-like element, for example, a glass sheet initially only at its lower end between two supporting structures with two fastening devices according to the invention are attached. The rotation of this fastening device according to the invention guarantees a subsequent alignment of the sheet-like element in the vertical or relative to the support structure, so subsequently. that is, after alignment, first the upper attachment devices must be attached to permanently fix the glass plate in position.

For the time being, this takes place in the individual steps in such a way that first the base bodies in the lower and upper area of the sheet-like element are mounted on the respective supporting structures. Subsequently, the receiving elements are mounted on the base body at the bottom of the sheet-like element. The sheet-like element is then inserted from above into the fastening device according to the invention, there in particular in the groove of the receiving element. As a result, the sheet-like element with its underside, for example a glass plate, is temporarily in two fastening devices according to the invention, which in turn are already fixed to the supporting structure. Subsequently, the receiving elements are placed on the upper remaining edge of the sheet-like element.

The larger selected length of the recesses, in particular the groove, now allows a displacement of these receiving elements on the upper edge of the sheet-like element in the direction of its inside. Subsequently, the plate can now be aligned with the supporting structure. After alignment, the receiving elements are inserted into the remaining two main body and thus fix the position of the sheet-like element permanently and safely.

In a further embodiment, securing means are formed on or in the main body. This provides for a still secure and permanent bond between the receiving element and the base body and thus further improves the secure position of the sheet-like element.

For this, the base body as a fastening means for fixing in a mounting base on a central bore. Through this centric bore a screw can be inserted, which determines the body permanently on the support structure. In a particularly advantageous embodiment of the invention, it is provided that the coupling means in the base body also receives the fastening means for fixing the base body to the supporting structure. This has the advantages that the attachment of the body after the assembly of the sheet-like element is no longer accessible. The number of components can also be reduced, which leads to a cost savings in the manufacture of the fastening device according to the invention.

Further advantageous in a fastening device according to the invention, the provision of the receiving element with a sheath. This casing may be made of stainless steel, for example, and thus in addition to an optical unit with the base body, the For example, made of stainless steel, protect the plastic body of the receiving element from weathering and UV light. In addition, the sheath offers aesthetic advantages. If the sheath has a groove parallel to the groove in the receiving element, it is ensured that always the receiving element has a single element direct contact with the sheet-like element. Dot loads in the sheet-like element can thus be avoided.

It is particularly advantageous if the sheathing carries the coupling means for fixing in the main body, since then the sheath can serve as a bush for the receiving element made of plastic and voltage peaks are avoided.

Another advantage of a fastening device according to the invention is that an anti-twist device is provided between the receiving element and the jacket. This prevents a rotation of the casing relative to the receiving element. Damage caused by direct contact of the sheathing on the glass plate, are thus almost impossible.

To further improve and reduce the stresses in the corner region of the sheet-like component, the invention provides that the receiving element is a damping element. Meanwhile, the damping distributes shocks on the glass plate and gives them only reduced to the base body, which in turn is rigidly attached to the support structure. As a result, damage to the sheet-like element, in particular the glass plate, avoided.
