Description

Holder for a frameless, flat glass element

The invention relates to a holder for a frameless, planar glass element, for example door element or wall element, with a holding profile which has a base region and two side regions which form a U-shaped receptacle for an edge region of the glass element.

In glass partitions, for example in office buildings, department stores, banks, etc., with essentially frameless door systems (hinged doors and sliding doors), it is known to fasten the fittings for the frameless doors to holes in the door leaf and in adjacent glass elements.

Thus, for example, EP 1 916 371 A2 discloses frameless sliding elements with the aid of two lugs with support rollers on the running surface of a running rail fastened to the fixed glass element. For the attachment of the sliding door elements corresponding holes are provided to secure the glass elements by means of screws to the tabs.

Furthermore, DE 103 29 518 A1 discloses a completely covered attachment of the upper glass rim of a frameless sliding door element, in which the carriage of the sliding door received in the interior of a guide rail is fastened to the upper edge of the sliding door and to two undercuts of a groove-shaped receptacle of the guide rail is guided. The carriage consists essentially of two lateral cheeks, between which a support body is arranged, which essentially has a height corresponding to the glass thickness. Left and right of the support body are the two support screws, which are received by corresponding holes in the glass element. The design achieves an appealing overall appearance, as all fastening elements for the glass element remain invisible to the outside. However, the construction is relatively expensive and expensive, since the glass elements per carriage used at least require a peripheral recess for the support body and two holes for the support screws, their production is particularly expensive in tempered safety glass.

There are also adhesive strips known, for example in the form of all-round frame profiles in shower partitions, which have a full-surface bonding, in which the adhesive is metered, for example, in a U-shaped profile and the glass element is inserted thereafter. It is also known to apply or apply the adhesive to a glass element and then the glass element together Glue into a U-profile. In these known measures the inclusion of air bubbles in the adhesive surface is unavoidable and also the supply of air for curing the adhesive is not given sufficiently. The well-known, full-surface bonding is therefore not suitable to take wearing functions.

The object of the present invention is to propose a holder for frameless, flat glass elements, in particular a one-sided holder for sliding or revolving door elements, which meets the high aesthetic requirements for partition walls with frameless glass elements and is nevertheless inexpensive to produce.

This object is achieved in that pairs of opposing adhesive wedges are arranged at the edge region of the glass element within the holding profile, which are acted upon by an elastically biased retaining clip with a directed onto the surfaces of the glass element contact pressure.

The holder of the invention is characterized in particular by the fact that the glass elements in the holding area need not be equipped with holes or with recesses, whereby the production cost can be reduced and the production costs can be significantly reduced. The highly prestressed steel retaining slats, together with the glued wedges, provide excellent holding forces, so that, for example, with a sliding door leaf, three retaining clips are sufficient for load-bearing attachment with sufficient safety reserve.

According to the invention, the retaining clips have a base region bridging the end face of the glass element and two clip arms, the retaining edges of which engage in a respective latching groove of the adhesive wedges.

To facilitate assembly, the retaining brackets following the retaining edges on obliquely outwardly directed end regions which cooperate with the frontal placing the retaining clips with inclined sliding surfaces of the attached at the edge region of the glass element adhesive wedges, elastically expand the retaining clips and engage the retaining edges in the locking grooves of the adhesive wedges to let.

For backlash-free fixation of the glass element and for additional absorption of load bores are arranged in the base region of the U-shaped receptacle at regular intervals, the access openings form a glue channel, which is bounded by the end face and the surfaces of the glass element inserted into the U-shaped receptacle , so through part of the holes an adhesive can be fed into the adhesive channel and the remaining part of the holes serves as a vent opening during the introduction of the adhesive and as a ventilation opening during the curing of the adhesive.

The adhesive forms next to and between the retaining clips a plurality of spaced apart adhesive dots or adhesive areas, which comprise the edge region of the glass element at the end face and on the two surfaces like a pincers. Preference is given to using a one-component adhesive of a solvent-free, isocyanate-free, modified polymer, preferably an MS hybrid polymer (for example Merbenit®: www.merz-benteli.ch).

The invention will be explained in more detail below with reference to drawings. Show it :

Fig. 6 shows a detail C of Fig. 5; such as

Fig. 7, the holder according to the invention shown in FIG. 5 in a sectional view in the area outside the retaining clips.

The holder shown in Figures 1 to 4 is used for supporting attachment of frameless, glass sheet 20 elements, such as a sliding door of the revolving door element, wherein the holding profile 1 has a base portion 2 and two side portions 3, 4, which has a U-shaped receptacle for the edge region of Form glass element 20. Covered by the U-shaped receptacle of the retaining profile 1 20 opposite pairs of adhesive wedges 5, 6 are arranged at the edge region of the glass element, which are acted upon by a resiliently biased retaining clip 7 made of steel with a directed to the surface 21 of the glass element 20 contact pressure.

Each adhesive wedge 5, 6 has an adhesive film 14 on the side facing the surface 21 of the glass element 20 (eg 3M VHB ™ high-performance connector). Systems 4936, 4941, 4956 or 4991: www.3m.com/at), and can be glued aligned on the end face 22 of the glass element 20.

The individual retaining clips 7 have a base region 8 bridging the end face 22 of the glass element 20, as well as opposite clip arms 9, the retaining edges 10 of which engage in a respective latching groove 11 of the adhesive wedges 5, 6.

To facilitate the attachment of the prestressed retaining clips 7, these have, following the retaining edges 10 obliquely outwardly directed end portions 12 which cooperate with the frontal placement of the retaining clips 7 with oblique sliding surfaces 13 of the adhesive wedges 5, 6, which are glued to the edge region of the glass element 20 ,

On the wider side of the adhesive wedges 5, 6 or on the side remote from the end face 22 of the glass element 20 side, a support surface 15 is formed, which is supported on the glass surface directed end legs 16 of the side portions 3, 4 of the holding section 1. The glass element 20 thus hangs in the holding profile 1 and is supported on the end legs 16.

When mounting a glass element 20, for example a sliding door element, the procedure is thus as follows:

The glass element 20 is cleaned in the edge region and made free of grease.

The adhesive wedges 5 and 6 are aligned on the end face 22 and glued in pairs opposite one another.

With a rubber hammer, the retaining clips 7 are opened, wherein the obliquely outwardly directed end portions 12 of the retaining clips 7 slide on the inclined sliding surfaces 13 of the adhesive wedges 5, 6 along.

The retaining edges 10 of the retaining clips 7 engage in the locking grooves 11 of the adhesive wedges 5 and 6, and press them permanently against the glass surface.

The retaining profile 1 is pushed onto the arrangement of adhesive wedges 5, 6 and retaining clips 7, so that the support surfaces 15 of the adhesive wedges 5, 6 come to rest on the end legs 16 of the side regions 3, 4 of the retaining profile 1.

After these assembly steps, a fixation of the holder can be made by gluing according to the invention. For this purpose, in the base region 2 of the U-shaped receptacle at regular intervals holes 17 are arranged (see Fig. 7), the access openings to form an adhesive channel 18 through the end face 22 and the surfaces 21 of the glass element 20 inserted into the U-shaped receptacle is limited. An adhesive 19 can now be fed into the adhesive channel 18 through part of the bores 17, the remaining part of the bores 17 serving as a vent opening during the introduction of the adhesive 19 and as a ventilation opening during the curing of the adhesive.

The adhesive 19 is preferably introduced in areas next to and between the retaining clips 7 and, after curing, comprises the edge region of the glass element 20 on the end face 22 and on the two surfaces 21 like a pliers.

The embodiment variant of the holder according to the invention shown in FIGS. 5 and 6 has a retaining clip 7 made of steel, the two clamping arms 9 of which have rounded retaining edges 10, each of which engages in a latching groove 11 of the adhesive wedges 5, 6. During assembly of the retaining clips 7, the rounded retaining edges 10 first slide along the bevelled sliding surfaces 13 of the adhesive wedges 5, 6 and then snap into a respective latching groove 11.

In the base region 8 of the retaining profile 1 extending bore channels 23 are provided parallel to the profile axis, which can receive connecting bolts for fastening abutting profile ends. The drill channels 23 are also used for screwing end caps of the retaining profile 1, not shown here.

The retaining profile 1 can be fastened in a supporting function both at the upper edge of a sliding door and on the hinge side of a revolving door by means of the retaining clips 7 and reinforced by the point bonding of the adhesive 19, wherein a plurality of receiving grooves are provided for fastening of fitting elements. Thus, the base region 2 of the retaining profile 1 on the side facing away from the glass element 20 on an undercut receiving groove 24 for fastening of fitting elements (Fig. 1, Fig. 6).

Furthermore, the retaining profile 1 in extension of at least one side region 4 on the opposite side of the U-shaped receptacle has a retaining flange 25 with at least one receiving groove 26 (Fig. 1, Fig. 6).
