Abstract

There is provided an improved door structure of the type having a frame supporting a panel of glass or other suitable material and characterized by very narrow stiles. The stiles each have relatively heavy face portions connected by a transverse web and defining confronting shallow and deep glazing pockets. Spaced upper and lower rail assemblies interconnect the stiles, and are each provided with longitudinally extending screw splines. The ends of the upper and lower rail assemblies are coped so that the screw splines fit within the confronting glazing pockets and seat against the respective webs.

Claims

1. A door structure of the type having a frame supporting a panel such as of glass and characterized by very narrow stiles, said door structures comprising:

spaced vertical door stiles, each having relatively heavy face portions connected by a transverse web defining confronting shallow and deep glazing pockets;

spaced upper and lower rail assemblies interconnecting said stiles;

;

at least one of said rail assemblies including;

a rail member having a generally tubular center portion having parts thereon defining longitudinally extending screw splines and a face portion, and a face member defining a glass stop and forming a glazing pocket with its face portion;

said rail member and said face member having interlocking parts;

the ends of said rail assemblies being coped with the ends of the screw splines fitted within the confronting shallow and deep glazing pockets of the door stiles and against the webs thereof, and fastener means extending through the transverse webs into said screw splines securing said rail assemblies and said vertical stiles together.

2. A door structure as set forth in claim 1 wherein channels are defined in the outer edges of said door stiles for receiving stile caps covering said screw fasteners.

3. A door structure as set forth in claim 2 wherein said door stiles define lock and pivot stiles respectively, each having the same width, and wherein the shallow glazing pocket is defined in said lock stile and the deep glazing pocket is defined in the pivot stile, and wherein the channel in said lock stile is deeper than the channel in said pivot stile, whereby said lock stile is adapted to receive door hardware associated with said stile.
