Corner connector for fire-resistant glass spacer frame

Abstract

The subject of the application is a corner connector (1) for a fire-resistant glass spacer frame. The connector (1) comprises two perpendicularly extending arms (21, 22), which are inserted into the spacer frame profiles. The arms (21, 22) are connected by a corner element (5). Each arm (21, 22) has a front surface (6), a rear surface, and a beveled end edge (9), while the corner element (5) has a front side (11), a rear side with a first and second wall perpendicular to each other, and a first front side (141) and a second front side (142), from which the arms (21, 22) of the connector extend. The front side (6) of the corner element (5) is formed as an arcuate surface with a radius R, while its rear side has a third oblique wall separating the first and second walls.In addition, diagonal chamfers (15) are formed at the junction of the first wall with the adjacent first front side (141) of the corner element (5) and at the junction of the second wall with the adjacent second front side (142) of the corner element (5).
