Overlapping framing system for glazing elements

A framing system for supporting glazing elements on a substrate, said framing system comprising:

• a plurality of frames, each frame surrounding and supporting one glazing element, each frame including a plurality of identical, extruded frame members joined to form sides of said frame, and corner coupling clips for connecting said frame members together at corners of said frame;
• each said frame member including
• a rabbet for receiving said glazing element having a base and a pair of parallel, spaced sides connected to said base and extending in a given direction therefrom,
• a pair of nubs extending from said sides of said rabbet forming a groove for receiving one said corner coupling clip,
• a pair of inwardly extending gaskets attached to said sides of said rabbet for securing said glazing element,
• a flange extending from said base substantially perpendicular thereto, in a direction generally opposite said given direction, a top surface of said flange positioned about midway along said base,
• a leg spaced from said base and extending from an end of said flange, said leg substantially parallel to said base, whereby a channel is formed by said leg, said flange and a portion of said base,
• a pair of notches in said channel, one notch in said leg and one notch in said portion of said base;
• wherein flanges of frame members overlap with flanges of adjacent frame members of adjacent frames, whereby the thickness of said framing system measured perpendicularly from said substrate is equal to the thickness of one said frame member, and wherein said channel of one frame member of said adjacent frame members faces inwardly toward said substrate and said channel of the other frame member faces outwardly away from said substrate whereby said channels face in opposite directions;
• a sealing gasket between overlapping flanges;
• a cap member received in each said outwardly facing channel, each said cap member including a top with spaced sides extending from said top and projections on said sides for engaging said pair of notches;
• and fasteners extending through said connecting flanges for attaching said framing system.
