Multipane insulated glazing plastic corner connector - with arms joined by unifying reinforcing unit shaped to promote cementing adhesion

摘要

The carrier-connecting angle-piece, for multi-pane insulated window glazing, is an inuection and moulded unit mode of plastic, with arms connected across the corner and insertable in adjacent shaped frame units, with a number of cross-section-fitting ribs extending across the line of the arms. In the area of the corner the arms are connected by means of a reinforcing unit which combines with them to form a unified entity, and the outer surface of this is profiled to improve the adhesive quality of the sealing medium, by means of transverse corrugations, or dovetailed or semicircular grooves. The surface may also be holed for the accommodation of the sealing medium. Rigidity and adhesion are enhanced, without any need for additional chemical media.
