Description

INSULATING ELEMENT

Technical area

The invention relates to the field of insulating glass elements, as they are used in particular in door and window construction.

State of the art

The production of insulating glass elements by gluing of profile frame and insulating glass unit is well known. As a rule, a profile frame is provided in which an insulating glass unit is inserted and glued. When inserting the insulating glass unit in the profile frame is to ensure the most accurate placement and alignment of the insulating glass unit. Typically, the placement is done by means of spacers, which are arranged at regular intervals along the frame. For example, such spacers are described in

DE 20 2005 016 949 U1.

A disadvantage of the use of spacers is that the attachment of such represents an additional step in the manufacture of insulating glass elements. Furthermore, there is a risk in the use of spacers that they are displaced when inserting the insulating glass unit or during the application of the adhesive and thus results in a defective end product.

Presentation of the invention

The object of the present invention is therefore to provide insulating glass elements which overcome the disadvantages of the prior art and manage without the separate use of spacers.

This object is achieved by an insulating glass element according to the features of claim 1.

The core of the invention is therefore an insulating glass element comprising a profile frame and an insulating glass unit consisting of at least two Glass panes, wherein one of the glass panes in the region of one of its glass edges or of two of their adjacent glass edges has an extension. The insulating glass unit is arranged in the profile frame so that it rests on this extension of the glass on the profile frame and is thus aligned correctly in this.

The advantage of the present invention is that the use of separate spacers, as described in the prior art, is eliminated. Instead, the insulating glass unit is provided with an extension of one of its glass edges or two of their adjacent glass edges, the insulating glass unit rests with this extension on the profile frame and is thus correctly placed and aligned without additional aids.

Further aspects of the invention are the subject of further independent claims. Particularly preferred embodiments of the invention are the subject of the dependent claims.

Ways to carry out the invention

FIG. 1 shows an insulating glass element 1 comprising

a profile frame 2 with a fold 3 for receiving an insulating glass unit 4, wherein the fold has a the insulating glass unit at the end enclosing peripheral surface 5 and the edge of the insulating glass unit cross folding surface 6; and

an insulating glass unit 4 consisting of at least two

Glass sheets 7a and 7b, which are arranged and spaced parallel to each other by means of spacers 8, wherein one of the outer

Glass has 7a in the region of one of its glass edges 9 or of two of their adjacent glass edges an extension 10. The insulating glass unit 4 is arranged in the profile frame 2 so that it rests on the extension 10 of the glass pane on the region facing the extension of the peripheral surface 5 of the profile frame 2. By resting the insulating glass unit on the extension 10 of the glass sheet on the region facing the extension of

Peripheral surface 5 of the profile frame, a gap 1 1 is formed between the, the insulating glass unit 4 frontally enclosing, peripheral surface 5 and the end face of the Isoherglaseinheit. This gap 11 is typically filled with an adhesive or sealant.

In particular, the insulating glass unit 4 is arranged in the profile frame 2 such that the glass pane 7a, which in the region of one of its

Glass edges 9 or of two of their adjacent glass edges the

Extension 10, the folding surface 6 faces, which engages over the edge of the Isoherglaseinheit. This arrangement facilitates depending on the profile design, the application of an adhesive or sealant.

Preferably, the extension of the glass sheet or the width of the gap formed thereby is in the range of 2 to 10 mm.

Furthermore, the extension of the glass pane extends in particular over the entire length of the glass edge. In certain cases, however, it may also be advantageous if the glass pane has an extension only in sections.

In a first, preferred embodiment of the invention, the isoher glass unit is an isoher glass unit, comprising at least two glass panes of different area size. In this case, the extension 10 is formed by the enlargement of the surface of one of the outer glass panes 7a with respect to the remaining glass panes 7b.

So are, for example, two glass sheets of different surface size to each other arranged so that at least two glass edges flush The result is an insulating glass unit which has a glass pane which has an extension in the region of one of its glass edges or of two of its adjacent glass edges. The extension is formed by the protruding section of the larger glass pane.

If the two glass panes of the insulating glass unit differ in their area size only in one direction and the two glass panes are arranged in such a way that three glass edges are flush, the result is an insulating glass unit which has a glass pane which has an extension in the region of one of its glass edges.

This preferred embodiment has the advantage that the extension of the glass pane in the production of the insulating glass unit can be realized with little effort and cost. The extension of a glass pane in the region of one of its glass edges or of two of its adjacent glass edges is formed in another embodiment by gluing or extrusion of a web in the region of a glass edge or of two adjacent glass edges of one of the outer glass panes.

FIG. 2 shows, for example, an insulating glass element, as shown in FIG. 1, wherein the extension of the glass pane in the region of its glass edge is formed by a web 101. The insulating glass unit 4 of Figure 2 is constructed of two glass sheets 7a and 7b, spacer 8 and secondary seal 14. Figure 2 also shows the gap filled with adhesive or sealant 12 between the, the insulating glass unit 4 end-enclosing send, circumferential surface 5 and Front side of the insulating glass unit.

FIG. 3 likewise shows an insulating glass element, as shown in FIG. 2, wherein the web 101 shown here, due to its shape, with appropriate materialization, absorbs the insulating glass unit to a certain degree on the profile frame. In the insulating glass unit 4, which is shown in Figure 3, takes over the adhesive or sealant 12, in addition to the bonding of the insulating glass unit with the profile frame, additionally the

Function as a secondary seal. The web shown in FIGS. 2 and 3 may consist of a

Any material which has the necessary properties to support the insulating glass unit on the profile frame. In particular, the selected material should have a sufficiently high rigidity in order not to bend under the load of the insulating glass unit.

The web is preferably a web made of plastic, in particular a thermoplastic, for example a polyolefin, such as polyethylene or polypropylene, polystyrene and the like.

The web is preferably designed such that the glass pane rests at least partially on the web via its glass edge, as can be seen in particular in FIG. As a result, the insulating glass unit is optimally supported on the profile frame.

The mounting of the web on the glass pane of the insulating glass unit is preferably carried out by gluing or extrusion.

If the insulating glass unit is an insulating glass unit with more than two glass panes, typically only one of the outer glass panes has an extension.

FIG. 4 shows an embodiment of an insulating glass element as shown in FIG

Figure 1 is shown, in which case an insulating glass unit is shown consisting of three glass panes. It has only one of the outer

Glass panes 7a in the region of one of its glass edges 9 an extension 10. The other two glass sheets 7b have no extension.

Furthermore, FIG. 4 shows the gap, filled with adhesive or sealant 12, between the peripheral surface 5 surrounding the insulating glass unit 4 and the end face of the insulating glass unit.

Another embodiment of an insulating glass element is shown in FIG. 5, for example. If the extension 10 of a glass pane 7a is one which is formed by the enlargement of the area of one of the outer glass panes relative to the remaining glass panes, then it is between the circumferential area 5 of the profile frame 2 and the glass edge 9 of the elongated glass pane 7a, preferably a damping element 13 is used. Furthermore, FIG. 5 shows an embodiment with a thermoplastic spacer 81.

The damping element is used in particular to compensate for stresses and pressure points, which arise when resting the insulating glass unit on the profile frame. The damping element can be formed, for example, from a foam layer or a layer of an elastic material. Likewise, the damping element may be formed from a textile material, for example a felt. The damping element may be further attached in the form of a paint on the profile frame.

The damping element can pointwise, in sections or continuously facing on the extension of the glass

Be attached portion of the peripheral surface of the profile frame.

Furthermore, the damping element may be provided with means for fixing it to the profile frame or to the glass edge of the extended glass pane. Such agents are in particular an adhesive layer.

For example, the damping element is a one-sided adhesive foam tape. As a profile frame for the inventive insulating glass element, any profile frame can be used, which has a suitable for receiving a Isolierglaseinheit, fold with one, the insulating glass unit frontally enclosing peripheral surface and, the edge of the insulating glass unit cross-folding surface. Typically, this is an L-profile or a U-profile or a profile having such an element.

Furthermore, the profile frame can be made of any material. In particular, the profile frame made of metal, plastic, wood or a combination of these materials. The profile frame is preferably an aluminum profile, a PVC profile or a wooden profile.

Figure 6 shows, for example, an insulating glass element 1, as shown in Figure 1, wherein the profile element 2 is a U-profile. In particular, the profile frame is a door or window frame, preferably a window frame. As the insulating glass unit for the present invention may be any

Insulating glass unit are used, which with a previous

provided extension is provided.

Typically, the insulating glass unit consists of two or three glass panes, each with a spacer arranged between the glass panes and optionally primary and secondary seals.

As a spacer, all commercially available spacers can be used. For example, these are spacers made of metal or plastic, optionally provided with a film for the gas-tightness and primary seal or so-called thermoplastic spacers which are applied as a hot melt composition based on polyisobutylene and form spacers and primary seal at the same time.

Most preferably, the insulating glass unit is one which does not have a secondary seal prior to bonding to the profile frame. When gluing insulating glass unit without secondary seal and profile frame with an adhesive or sealant, this covers the entire area of the front side of the insulating glass unit. As a result, the adhesive or sealant additionally serves as a secondary seal for the insulating glass unit. The advantage of this embodiment is that can be dispensed with in the manufacture of the insulating glass unit on the secondary seal, whereby their production can be made both time and cost-saving.

If the insulating glass element is one in which the adhesive or sealant also forms the secondary seal of the insulating glass unit, the spacer is arranged in particular so that it projects beyond the glass panes by a few millimeters, in particular by approximately 2 to 10 mm becomes. This leads to an optimal sealing of the insulating glass unit by the adhesive or sealant. In the area of the extension of a glass pane, the glass pane projects beyond the spacer accordingly in addition to the length of the extension, as previously described.

When adhesive or sealant, with which the Isolierglaseineinheit is glued to the profile frame is in particular a

Composition based on polyurethane, silicone or acrylate.

The application of the adhesive or sealant in the gap 1 1 is typically carried out with the aid of a suitable application nozzle. If the profile element is an L-profile, the adhesive or sealant can be applied directly from the side opposite the folding surface into the gap.

If the profile frame is a U-profile, the

Application of the adhesive or sealant typically by means of application nozzle, which can be inserted into the space between the insulating glass unit and profile frame.

The adhesive or sealant can be located in the entire region of the front side of the insulating glass unit or even only on parts of the front side, typically on the glass edge of a glass pane of the insulating glass unit, which does not have the extension.

Forms the adhesive or sealant, the secondary seal of

Insulating glass unit, it is typically applied so that it covers the entire end face of the insulating glass unit. Most preferably, the insulating glass element is a

Window or a door.

For example, Figure 7 shows a window frame 21 with a fold 3 for receiving an insulating glass unit 4, wherein the fold one, the

Insulating glass unit enclosing the front side, peripheral surface 5 and one, the edge of the insulating glass unit cross-folding surface 6 has. Furthermore, FIG. 7 shows an insulating glass unit 4 consisting of at least two

Glass sheets 7a and 7b, which by means of spacers 8 parallel to each other are arranged and spaced. The glass pane 7a has an extension 10 in the region of one of its glass edges 9.

As a spacer 8 here is a spacer with primary seal, as has been previously described. The illustrated insulating glass unit has no secondary seal. The secondary seal is formed by the adhesive or sealant 12 with which the insulating glass unit is adhered to the window frame 21.

The insulating glass unit 4 is arranged in the window frame 21 so that it rests on the extension 10 of the glass pane on the region facing the extension of the peripheral surface 5 of the window frame 21.

Furthermore, the present invention relates to a method for

Production of an insulating glass element 1 comprising an insulating glass unit 4 and a profile frame 2 comprising the steps

- Providing an insulating glass unit 4 consisting of at least two glass sheets 7a and 7b, which are arranged and spaced apart by means of spacers 8, wherein one of the outer glass panes 7a in the region of one of its glass edges 9 or two of their adjacent glass edges has an extension 10;

- Providing a profile frame 2 with a fold 3 for

Recording of an insulating glass unit 4, wherein the fold a, the insulating glass unit frontally enclosing, circumferential surface 5 and one, the edge of the

Profile frame 2 rests;

Introduction of an adhesive or sealant 12 between insulating glass unit 4 and peripheral surface 5 of the profile frame second

The inventive method has the advantage that the insulating glass unit without the use of separate spacers in

Profile frame can be aligned. The insulating glass unit can in the lying or in an upright frame.

In particular, the insulating glass unit is inserted into the upright or slightly inclined profile frame, which rests on the extension of the glass sheet on the profile frame.

If the insulating glass unit in the X- and Y-direction in the profile frame be extended, an insulating glass unit is typically used, which has an extension in the region of two of their adjacent glass edges. In this case, the profile frame can be placed upright when inserting the insulating glass unit, by an angle in the range of> 0 ° to <90 °, in particular in the range of about an axis perpendicular to the plane in which the insulating glass unit comes to rest 45 °, is rotated. In this position, the insulating glass unit so in the

Profile frame are used so that it rests on both sides of the extensions of the glass pane on the profile frame.

Furthermore, the present invention relates to an insulating glass unit, as shown for example in one of the figures 8 or 9.
