ABSTRACT:
A corner gusset for fastening the corners of a hollow frame structure such as those employed in the fabrication of some types of doors. The gusset comprises a first member providing two legs in the general form of an angle bracket with inwardly turned end flanges, and a second member, comprising a draw-bar, fixed in a spanning relation between the two legs of the angle bracket. Opposed end portions of the draw-bar are angled relative to the main span thereof to lie against the respective inner faces of the two legs adjacent the inwardly turned end flanges. An outwardly extending lug from each of the angled end portions extends through a companionately shaped end sized hole through one of the inwardly turned end portions to securely hold the two members in assembly. When the assembled gusset is inserted in place in a corner of the hollow frame structure, fasteners such as screws are engaged through appropriately positioned holes in the two hollow frame members, defining said corner, and mating holes in the gusset. The structure is inherently designed and proportioned to provide a light weight but strong gusset in which very substantial material savings are insured.
