Patent ID: 8240940

Claim:
A corner connector for use with glass pane spacers used for maintaining a space between two glass panes, comprising: a first connecting element defining a first axis and a second connecting element defining a second axis, on each of which a spacer having a substantially flat end surface can be mounted, and a corner element, which joins the first and second connecting elements at an angle defined by said first and second axes, wherein the corner element has two lateral surfaces adapted to face the glass panes, two end surfaces each arranged perpendicular to the respective axis of the adjoining first or second connecting element so as to face the substantially flat end surface of the spacer adapted to be mounted thereon, an inner area adjacent each of said two end surfaces, and an outer surface, wherein a metal foil is applied to the outer surface and at least partially to the lateral surfaces and the end surfaces, a butyl is provided in the area of the end surfaces, which creates a seal between the metal foil and the spacer adapted to be mounted thereon, and in each inner area of the corner element there is provided a stop surface that is spaced from its respective end surface in the axial direction perpendicular to said respective end surface so that a gap is created in said axial direction between said respective end surface and the substantially flat end surface of the spacer in an outer area of said corner element when the spacer is mounted on one of the first and second connecting elements and abuts said stop surface.
