ABSTRACT:
In a spacer frame for use in separating panes of glass of an insulated glass panel, a cornerpiece has first and second arms joined by a flexible hinge to permit angular movement of said arms with respect to one another. The first and second arms each have a first portion that has a cross-sectional area substantially equal to the cross-sectional area of a spacer bar into which they are inserted, and a second portion that protrudes from the spacer bar that is of a cross section larger than said first portion to form a shoulder that is adjacent and abutting the end of the spacer bar. The shoulder is substantially continuous around its perimeter to substantially eliminate moisture paths from outside said spacer bar to the interior of the spacer bar. The folded corner presents an essentially solid mass that prevents moisture from entering the spacer bar. The cornerpiece also includes an angled projection that extends from a first end of the first arm and a slot formed in the first end of the second arm, the projection and slot cooperating with one another to form an interference fit that releasably holds the first and second arms in a desired angular relationship. A first surface of each of said first and second arms has a series of sawtooth-like serrations formed thereon that interferes with an interior surface of the spacer bar to aid in maintaining the arm in the spacer bar.
