A construction for removably retaining a first sheet of glazing adjacent to a second sheet of glazing is disclosed including a fixed frame member adapted to be attached to a glazing cap, and a removable retaining flange connectable to the fixed frame member. The flange-holding side wall of the fixed frame member has a shoulder containing a longitudinal groove adjacent to the flange, and a longitudinal recess having an upper edge and a lower edge including a catch. The retaining flange connects to the fixed frame member by nesting the upper end edge of a vertical leg of the flange into the flange-holding groove of the frame member and locking a lip of the flange member to the catch along the lower edge of the fixed frame recess. When the fixed frame member and the removable retaining flange are connected, the flange of the fixed frame member and the horizontal leg of the removable retaining flange removably brace a first sheet of glazing therebetween. |

DETAILED DESCRIPTION The present invention is a construction for removably retaining an inner glazing sheet preferably comprised of light transmissive insulating material adjacent to a second sheet or dome of glazing.
The outer glazing is usually exposed to the elements.
A glazing cap and a glazing frame fixed to the inside perimeter of the cap are adapted to be securedly attached to structural supports of a house or building that define a glazing opening.
The second, usually exterior, glazing is held between the cap flange and an opposing shoulder of the fixed frame.
A removable retaining flange cooperating with the fixed frame removably holds the inner glazing sheet in place and braces it against environmental loads such as snow, rain and wind should the second, usually outer, glazing fail.
In a first embodiment of the present invention, the fixed frame member includes a top wall, bottom wall, two side walls, and a flange.
The flange is attached to one of the two side walls and is parallel with the top wall.
The flange-holding side wall has a shoulder containing a longitudinal groove adjacent to the flange, and a longitudinal side wall recess below the flange.
The lower edge of the recess includes a catch edge and a seat that mate with the removable retaining flange to allow bracing of the inner glazing sheet.
In another aspect of the first embodiment, the removable retaining flange has a vertical leg and a horizontal leg.
The end of the vertical leg mates in the groove of the fixed frame member shoulder during connection.
The vertical leg has a lip that includes a recess angled to engage with the catch edge of the fixed frame member catch during connection.
The lip additionally has a first face that is adjacent the lip recess and that fits flushly with the seat of the fixed frame member catch during connection.
The lip also has a second face that is adjacent the first face and fits flushly with the side wall recess of the fixed frame member during connection.
Thus, when the fixed frame member and the removable retaining flange are connected, the flange of the fixed frame member and the horizontal leg of the removable retaining leg removably brace the inner glazing sheet
