Abstract
Abstract A frame structure for supporting window and panel materials, wherein the frame structure comprises a vertical mullion assembly and a horizontal transom assembly joined together to form various sized frame-supporting structures. Both the mullions and transoms are formed from elongated channel-like extrusions adapted to receive different sized windows and panels, particularly for construction of outer walls of buildings. The windows and panels alike are locked into place by a snap-in casing that is accommodated in both the mullions and transoms. The transom assembly is secured in and supported by the upright mullion assembly, which when assembled together form a box-like frame structure having the windows and panels supported therein.

Total Claims: 12
Claim 1
Independent Claim
267 words
A curtain wall, having a frame structure for supporting window and panel members, comprising: a plurality of mullion assemblies vertically positioned and equally spaced in parallel relationship to each other within said frame structure; a plurality of transom assemblies horizontally positioned between each of said mullion assemblies, said transom assemblies being spaced apart in a parallel predetermined distance; a removable interlocking means between the outer free ends of said transom assemblies and said mullion assemblies; and means for removably securing said window or panel members within said mullion and said transom assemblies, wherein each of said mullion assemblies comprises: an elongated mullion extrusion member having oppositely disposed dual channel members, each of said channels having the same bottom wall, and at least one pair of parallel side walls extending therefrom, said side wall being spaced apart with suitable clearance for said window or panel members, and securing means to be inserted therebetween, said side walls being provided on their inner faces with sealing grooves and longitudinal ribs, wherein said free ends of said transom assemblies can be removably engaged therewith, and means provided within said ribs for supporting said interlocking means; and wherein each of said transom assemblies comprises: a first transom extrusion member; a second transom extrusion member identical to said first extrusion member, both being reversibly fitted into each other; oppositely-disposed dual channels formed by said reversiblyfitted extrusions, each channel having extending side walls suitably spaced apart to receive said securing means and said window or panel members therebetween, said walls being provided on their inner faces with integral longitudinal support ribs and sealing grooves.
Claim 2
Dependent Claim
267 words
A curtain wall, having a frame structure for supporting window and panel members, comprising: a plurality of mullion assemblies vertically positioned and equally spaced in parallel relationship to each other within said frame structure; a plurality of transom assemblies horizontally positioned between each of said mullion assemblies, said transom assemblies being spaced apart in a parallel predetermined distance; a removable interlocking means between the outer free ends of said transom assemblies and said mullion assemblies; and means for removably securing said window or panel members within said mullion and said transom assemblies, wherein each of said mullion assemblies comprises: an elongated mullion extrusion member having oppositely disposed dual channel members, each of said channels having the same bottom wall, and at least one pair of parallel side walls extending therefrom, said side wall being spaced apart with suitable clearance for said window or panel members, and securing means to be inserted therebetween, said side walls being provided on their inner faces with sealing grooves and longitudinal ribs, wherein said free ends of said transom assemblies can be removably engaged therewith, and means provided within said ribs for supporting said interlocking means; and wherein each of said transom assemblies comprises: a first transom extrusion member; a second transom extrusion member identical to said first extrusion member, both being reversibly fitted into each other; oppositely-disposed dual channels formed by said reversiblyfitted extrusions, each channel having extending side walls suitably spaced apart to receive said securing means and said window or panel members therebetween, said walls being provided on their inner faces with integral longitudinal support ribs and sealing grooves.
Claim 3
Dependent Claim
44 words
A curtain wall, as recited in claim 1, wherein said means for removably securing said window or panel members within said mullion and said transom assemblies comprises: a snap-in casing member adapted to be received in said channels of said mullions and transom assemblies.
Claim 4
Dependent Claim
84 words
A channel wall as recited in claim 2, wherein said snap-in casing member comprises: a flat wall; a depending side wall; a sealing groove in said side wall; a lip member extending outwardly from said side wall and adapted to frictionally engage at least one of sais ribs within said channels of both assemblies; and an arm member depending from the opposite side of said flat wall and provided with an outwardly-extending shoulder for positive locking engagement with at least one of said grooves.
Claim 5
Dependent Claim
75 words
A curtain wall, as recited in claim 3, wherein said removable interlocking means comprises: a pair of support pins fixedly mounted within the channels of said mullion extrusions and extending outwardly from said bottom wall of said channeLs to support the free ends of said transom assemblies thereon; and a pair of corresponding notches provided within both ends of at least one of the transom extrusions, said notches being positioned to receive oppositely-disposed ribs therein.
Claim 6
Dependent Claim
92 words
A curtain wall, as recited in claim 3, wherein said removable interlocking means comprises: an angle member removably mounted within each of said channels of said mullion extrusions for supporting the free ends of said transom assemblies thereon; and a pair of notches, each of which is provided within oppositely-disposed ribs of said channels of said mullion extrusions for supporting the free ends of said transom assemblies thereon; and a pair of notches, each of which is provided within oppositely-disposed ribs of said mulltion extrusions for receiving and supporting said angle members.
Claim 7
Dependent Claim
43 words
