DE202004017398U1 - Space frame for double glazed window has interlocking herringbone fittings with moisture-exclusion flap - Google Patents

Abstract

A double-glazed window has two panes of glass separated by an inner frame consisting of side-profiles linked at each right angled corner by a push-fit herringbone fitting. The socket zone has an air exclusion flap (8) that is closed over a measured quantity of butyl adhesive.

Description

The The invention relates to a plastic plug-in connector for with absorbent granules filled spacer hollow profile strips, the outward-facing Edge chamfers between glass sheets sealed with Butylkitt arranged are, wherein the male connector has a corner piece, of which Einsteckschenkel extend into the hollow profile strips, in which they with retaining slats are held securely against undressing.

Arrangements of plug-in connectors in hollow spacer profile strips between insulating glass panes are known from the DE 195 27 930 A1 known. The plastic connector has a U- or hollow profile, so that the granules during filling of the strips can run through the one, on the other hand, the passage can be prevented by a cross bar. Outer surfaces of the connector are provided with ribs, nubs, od. Like., So that a good interference fit is ensured in the hollow profile strips and these do not pull apart on thermal length changes over the connector. The cavity of the strips is connected by narrow punctures with the space between the discs for the purpose of gas exchange. In order to prevent the ingress of moisture between the glass panes and possibly the escape of high molecular weight filling gas from the gap outside of it on the profile strip a centimeter thick layer of Thiokol or similarly mounted between the discs, including a significant amount of expensive sealant is consumed.

It is also known, through a formation of outer edge chamfers on the hollow profile strip by introducing the Thiokol only in the Throat areas adjacent to the discs less sealing material to consume. A tightness of joints of with a corner plug-in connector but coupled hollow profile strips is not characterized given, and it requires complex single-sealing measures of the joints.

It Object of the invention is a simple and secure sealing a Corner joint by a suitable embodiment of a Eckstecksteckverbinders to provide.

The solution is that the Einsteckschenkel each in the area in front of the corner piece, the edge throat touched on its lateral edge with a flat section and each directed to the corner piece corner-sided slat one with a film hinge at its lamellar edge wearing hinged flap, in their width under the outer Hohlprofilwandung fits and each pushed over by the hollow profile is kept spaced from the flat portion, wherein the gap under the flap is filled with swelling Butylkitt.

advantageous Embodiments are specified in the subclaims.

The Flap that is spaced above the Einsteckschenkel is held swung up to a lamella, is prior to insertion into the hollow section with an excess of Butylkitt or a similar one relined permanently elastic sealing putty. When pushing the Hollow profiles lowers the flap on the Einsteckschenkel increasingly in the direction of the more outwardly projecting corner piece, so that the Putty z. T. laterally squeezed out in the edge throat and the corner piece out and there it provides an absolute tightness. The flap extends folded down with its leading edge to near the gradation of the corner piece.

Advantageous embodiments are the 1 and 2 refer to:

1 shows enlarged side view of the corner connector with a partially deferred hollow profile;

2 shows a perspective view with a completely deferred hollow profile 1 ,

1 shows enlarged Eckvebinder for a spacer hollow section H, which on a Einsteckschenkel 3 partially shown plugged. This hollow section H has on the outside edges edge chamfers R, is introduced into the butyl putty, which seals the insulating glass panes, not shown here, which are placed on both sides of the moldings H, to the space between the frame and the glass sheets back. The hollow profile strips H are filled with absorber granules, and their interior is connected by small openings with the space, so that vapors can get into the absorbent granules and are bound there.

The corner connector has a solid corner piece 1 on, which is formed approximately as a cylinder quadrant and radially has a profile with the edge chamfers R as the hollow section H. The inner cross-section of the hollow section H are the Einsteckschenkel 2 . 3 adapted trained. These contribute to the outside of the frame and towards the corner directed slats 4 . 5 , which anchor under elastic tension in the hollow section H against pulling out.

In the corner area is the Einsteckschenkel 2 . 3 formed thickened to the inner edge K of the edge of the throat R, where he forms a flat section 6 , Over this is a flap 8th pivotable on the corner of the lamellar edge 7 hinged, which when parallel to the section 6 from this and from one stage 11 the corner piece 1 is slightly spaced. As a result, Butylkitt B, which is introduced there before the sliding of the hollow sections H, squeezes at the stage 11 out and seals the corner piece against the hollow profile ends H from. This Kitt B combines homogeneously with the introduced into the edge chamfers R and ensures a complete seal.

The flap 8th fits in its width inside under the hollow profile outer wall HA, which extends between the edge chamfers R. Preferably, the flap 8th directed towards the outer wall HA with a transverse ribbing 12 Mistake.

It is expert Do, with the surfaces of the Einsteckschenkel shown here smooth Nubs, slats or the like to provide.

2 shows the corner connector in perspective view. On the downwardly directed leg, the hollow profile end is shown completely pushed. The one on the corner piece 1 swollen Butylkitt B is shown. It extends over the hollow profile outer wall HA and the edge fillets R continuously, so that it seals completely after filling the edge fillets R. It can be seen that the width of the flap 8th to the inside of the hollow profile outer wall HA fits.
