Abstract

A joint structure for connecting framing components such as sash members for a window is disclosed having separate functional and decorative junctions between adjacent framing components. The functional junction between components may be formed between opposing and abutting mitered mating surfaces defined at adjacent ends of the component, and a separate squared flange and cooperative recess may be formed on interior surfaces of the components for overlapping the mating surfaces and providing a decorative junction, for example, having the appearance of a mortise and tenon joint. The joint structure is particularly suited for use in custom or replacement applications whereby lineal extruded members formed of a heat weldable material may be cut to size having the aforementioned surfaces, and then heat welded together to form a custom sized framing structures such as a sash or frame for a window or door.

Claims

1. A heating platen for use in joining adjacent ends of first and second framing members, each having first and second sides and a mating portion disposed at an end of the framing member, wherein each mating portion is formed of a heat weldable material and includes a mating surface defined thereon for mating with a mating surface defined on the other mating portion, the first framing member including a flange disposed on the first side of the first framing member at said end thereof, and the second framing member including a recess defined on the first side of the second framing member at said end thereof, the recess for receiving the flange on the first framing member, the heating platen comprising first and second opposing heating surfaces for contacting the mating surfaces of the first and second framing members, respectively, wherein the first heating surface has a recess defined thereon for receiving the flange on the first framing member;

whereby the flange does not contact the heating surfaces while the heating platen applies heat to the mating surfaces.

2. The heating platen of claim 1, wherein each framing member is a sash member including a glass receiving channel formed between the first and second sides thereof, the glass receiving channel for supporting interior and exterior sides of a window glass assembly, and wherein the heating platen further comprises a glass receiving recess extending between the first and second opposing heating surfaces for receiving the window glass assembly;

whereby the heating platen is adapted to heat the mating surfaces of the first and second framing members while the window glass assembly is at least partially disposed within the glass receiving channel.
