Abstract
Abstract A curtain wall structure includes common extruded aluminum members which are assembled to form narrow profile vertical and horizontal mullions defining bay frames for supporting panels of glass or other structural panels. Frames for casement operating windows or vents are formed from similar extruded aluminum members, with the vent frames interfitting with the bay frames to maintain the narrow profile appearance of the curtain wall mullions. The common framing members are L-shaped in cross section defining side walls and face walls, with the face walls providing the narrow profile appearance; and are configured so that two framing members interfit with each other to maintain the narrow profile appearance. The framing members include longitudinal grooves which define panel supporting channels in the bay frames, or which retain longitudinal stops defining alternative panel supporting channels.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
A curtain wall structure comprising vertical and horizontal mullions defining at least one bay frame; said mullions comprising elongated framing members; a vent frame comprising elongated vertical and horizontal framing members; said framing members for said bay frame and said vent frame being common to each other; each of said common framing members comprising a unitary member of generally L-shaped cross section defined by a side wall and a transverse face wall, said face wall defining a face profile of said member; and said vent frame being dimensioned to interfit with a bay frame wherein the bay frame face walls and vent frame face walls are disposed in superposed relation whereby said vent frame is substantially merged with said bay frame as viewed from a face of the curtain wall structure, with the distal edges of respective side walls confronting the face walls of the interfitting frame member to define a box frame structure.
Claim 2
Dependent Claim
154 words
A curtain wall structure comprising vertical and horizontal mullions defining at least one bay frame; said mullions comprising elongated framing members; a vent frame comprising elongated vertical and horizontal framing members; said framing members for said bay frame and said vent frame being common to each other; each of said common framing members comprising a unitary member of generally L-shaped cross section defined by a side wall and a transverse face wall, said face wall defining a face profile of said member; and said vent frame being dimensioned to interfit with a bay frame wherein the bay frame face walls and vent frame face walls are disposed in superposed relation whereby said vent frame is substantially merged with said bay frame as viewed from a face of the curtain wall structure, with the distal edges of respective side walls confronting the face walls of the interfitting frame member to define a box frame structure.
Claim 3
Dependent Claim
154 words
A curtain wall structure comprising vertical and horizontal mullions defining at least one bay frame; said mullions comprising elongated framing members; a vent frame comprising elongated vertical and horizontal framing members; said framing members for said bay frame and said vent frame being common to each other; each of said common framing members comprising a unitary member of generally L-shaped cross section defined by a side wall and a transverse face wall, said face wall defining a face profile of said member; and said vent frame being dimensioned to interfit with a bay frame wherein the bay frame face walls and vent frame face walls are disposed in superposed relation whereby said vent frame is substantially merged with said bay frame as viewed from a face of the curtain wall structure, with the distal edges of respective side walls confronting the face walls of the interfitting frame member to define a box frame structure.
Claim 4
Dependent Claim
154 words
A curtain wall structure comprising vertical and horizontal mullions defining at least one bay frame; said mullions comprising elongated framing members; a vent frame comprising elongated vertical and horizontal framing members; said framing members for said bay frame and said vent frame being common to each other; each of said common framing members comprising a unitary member of generally L-shaped cross section defined by a side wall and a transverse face wall, said face wall defining a face profile of said member; and said vent frame being dimensioned to interfit with a bay frame wherein the bay frame face walls and vent frame face walls are disposed in superposed relation whereby said vent frame is substantially merged with said bay frame as viewed from a face of the curtain wall structure, with the distal edges of respective side walls confronting the face walls of the interfitting frame member to define a box frame structure.
Claim 5
Dependent Claim
37 words
A curtain wall structure as set forth in claim 1 wherein said box frame structure defines an enclosed chamber for enclosing and concealing an articulating hinge for supporting the vent frame relative to the vent opening frame.
Claim 6
Dependent Claim
37 words
A curtain wall structure as set forth in claim 1 wherein the distal edge of a framing member side wall defines an edge wall for confronting sealing engagement with the face wall of an interfitting framing member.
Claim 7
Dependent Claim
33 words
A curtain wall structure as set forth in claim 3 including seal strip means mounted on the inner surface of said framing member face wall for sealing engagement with the interfitting edge wall.
Claim 8
Dependent Claim
36 words
A curtain wall structure as set forth in claim 1 wherein the framing member side wall includes inner and outer facing longitudinal grooves for providing panel supporting channels in the frames defined by said framing members.
Claim 9
Dependent Claim
116 words
A curtain wall construction as set forth in claim 5 wherein said inner facing groove is disposed adjacent to the distal edge of said side wall and is provided with confronting undercut side walls; and elongated stop members for interlocking engagement with said framing members; said stop members having resilient oppositely facing lips for locking engagement with said undercut inner facing grooves; said stop members providing a face wall opposite from the framing member face wall and defining, with the framing member face wall, a groove providing a panel receiving channel; and said stop member and framing member defining an edge profile corresponding in width to the edge profile defined by the framing member face wall.
Claim 10
Dependent Claim
27 words
A curtain wall structure as set forth in claim 6 wherein said stop member face wall exterior surface defines a continuation of the framing member edge wall.
Claim 11
Dependent Claim
79 words
A curtain wall structure as set forth in claim 6 wherein said outer facing groove defines a panel supporting channel adjacent to the face wall; and wherein said stop member defines, with the face wall, an inner facing panel supporting groove directly opposite said outer facing groove; said stop member coacting with said framing member to define a face wall profile opposing the framing member face wall profile, and a partial side wall opposing the framing member side wall.
