Abstract
Abstract The skylight may be of the domed-type or flat-type and of single or double glass (acrylic or other transparent or translucent plastic) construction. The skylight fits within an opening in a roof or the like and has a peripheral base that may be constructed of a metal material such as aluminum, and which is fixed to the roof about the opening. The base comprises inner and outer base frames separated by a thermal break, a peripheral curb frame disposed over the base, and a retainer for securing the skylight cover over the curb frame. The curb frame or support frame has inner and outer sections connected by a heat insulating thermal barrier. The curb frame is constructed by welding at the corners of the support frame but eliminating the welding in the area of the thermal barrier thus alleviating a caulking operation at the top and the bottom of the curb frame. The base frame and curb frame have therebetween a compliant sealing means extending contiguously about and overlying the base frame and for sealing between the base frame and support frame.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
152 words
A skylight construction for an opening in a building or the like comprising; a frame means extending about the opening and including means secureable about the opening, translucent or transparent means covering the opening and extending at edges to overlie the frame means, means for retaining the covering means on the frame means, said frame means comprising a base frame and a support frame overlying the base frame, said support frame having inner and outer sections connected by a heat insulating thermal barrier, each said section including multiple pieces joined at corners of the support frame, means providing welding at said corners of the support frame including an interruption of the weld in the area of said thermal barrier so as to form a self-draining liquid path about the thermal barrier said base frame and support frame defining therebetween a continuation of the liquid path unobstructed to external of the frame means.
Claim 2
Dependent Claim
152 words
A skylight construction for an opening in a building or the like comprising; a frame means extending about the opening and including means secureable about the opening, translucent or transparent means covering the opening and extending at edges to overlie the frame means, means for retaining the covering means on the frame means, said frame means comprising a base frame and a support frame overlying the base frame, said support frame having inner and outer sections connected by a heat insulating thermal barrier, each said section including multiple pieces joined at corners of the support frame, means providing welding at said corners of the support frame including an interruption of the weld in the area of said thermal barrier so as to form a self-draining liquid path about the thermal barrier said base frame and support frame defining therebetween a continuation of the liquid path unobstructed to external of the frame means.
Claim 3
Dependent Claim
19 words
A skylight construction as set forth in claim 1 wherein said covering means includes at least one plate means.
Claim 4
Dependent Claim
15 words
A skylight construction as set forth in claim 2 including a pair of glass plates.
Claim 5
Dependent Claim
38 words
A skylight construction as set forth in claim 1 wherein said retaining means includes a retainer having one side extending downwardly about the base frame and another side extending inwardly to contact the edge of the covering means.
Claim 6
Dependent Claim
38 words
A skylight construction as set forth in claim 4 including securing means for securing the retainer to the support frame sandwiching the edge of the covering means between the support frame and the other side of the retainer.
Claim 7
Dependent Claim
53 words
A skylight construction as set forth in claim 1 wherein said base frame comprises an inner base frame and an outer base frame, said base frame being constructed of metal and separately formed of straight pieces to form individual frames and means defining a heat insulating thermal break between inner and outer frames.
Claim 8
Dependent Claim
31 words
A skylight construction as set forth in claim 6 wherein said thermal break includes a compressible tape having shim means to limit the separation between the inner and outer base frames.
Claim 9
Dependent Claim
34 words
A skylight construction as set forth in claim 7 wherein the inner and outer frames each include a leg, one leg overlying the other with the tape therebetween, and means securing the legs together.
Claim 10
Dependent Claim
25 words
A skylight construction as set forth in claim 1 including a cup-shaped gasket carried by the support frame and upon which the covering means rests.
Claim 11
Dependent Claim
32 words
A skylight construction as set forth in claim 1 including a compliant sealing means extending contiguously about and overlying the base frame and for sealing between the base frame and support frame.
Claim 12
Dependent Claim
17 words
A skylight construction as set forth in claim 10 wherein said sealing means comprises a hollow gasket.
Claim 13
Dependent Claim
53 words
A skylight construction as set forth in claim 10 wherein said support frame inner section has wall means depending below said thermal barrier and contacting the top of the sealing means so as to space said sealing means from said thermal barrier to provide a liquid leakage path from the support frame outwardly.
Claim 14
Dependent Claim
40 words
A skylight construction as set forth in claim 12 wherein said wall means in part defines a condensation gutter underlying said covering means, said path extending from said gutter over said sealing means and intermediate the base and support frames.
Claim 15
Dependent Claim
159 words
A skylight construction for an opening in a building or the like comprising; a frame means extending about the opening and including means secureable about the opening, translucent or transparent means covering the opening and extending at edges to overlie the frame means, means for retaining the covering means on the frame means, said frame means comprising a base frame and a support frame overlying the base frame, said support frame having inner and outer sections connected by a heat insulating thermal barrier, a compliant sealing means extending contiguously about and overlying the base frame and for sealing between the base frame and the support frame, said support frame inner section having wall means depending below said thermal barrier and contacting the top of the compliant sealing means so as to space said sealing means from said thermal barrier and from said support frame outer section so as to provide a liquid leakage path from the support frame outwardly.
Claim 16
Dependent Claim
