Abstract
Abstract A skylight that may have a domed-type or flat-type glazing and which is adapted to fit within the opening of a roof or the like having a peripheral frame which is fixed to the roof about the opening. The frame is constructed including a base frame and an operating leaf frame usually referred to as an operating leaf frame or operating leaf. A retainer is used for securing the skylight cover over the operating leaf frame. The frame comprises a rigid plastic profile (core) having high temperature resistant properties and a plastic capping material extruded over the external exposed surface of the core to protect the profile from weathering. There is also preferably provided with the profile and capping, a flexible gasket means which may include respective gaskets associated with both the base frame and the operating leaf frame.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
203 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 frame means having at least said base frame comprised of a rigid plastic core having high temperature resistant properties, and a plastic capping material extruded over the external exposed surface of the core to protect the core from weathering, said base frame having at least one flexible gasket integrally formed with said plastic core, said integral flexible gasket comprising a gasket extending from and integral with a top horizontally-disposed wall of the base frame and disposed sandwiched between the base frame and overlying support frame, said plastic capping material being substantially thinner than the thickness of the base frame, being less rigid than the plastic core and terminating at the base of the flexible gasket so that the gasket is absent a covering of the capping material so that the gasket maintains its flexibility.

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 frame means having at least said base frame comprised of a rigid plastic core having high temperature resistant properties, and a plastic capping material extruded over the external exposed surface of the core to protect the core from weathering, said base frame having at least one flexible gasket integrally formed with said plastic core, said integral flexible gasket comprising a gasket extending from and integral with a top horizontally-disposed wall of the base frame and disposed sandwiched between the base frame and overlying support frame, said plastic capping material being substantially thinner than the thickness of the base frame, being less rigid than the plastic core and terminating at the base of the flexible gasket so that the gasket is absent a covering of the capping material so that the gasket maintains its flexibility.
Claim 3
Dependent Claim
22 words
A skylight construction as set forth in claim 1 wherein said support frame comprises an operating leaf frame overlying the base frame.
Claim 4
Dependent Claim
29 words
A skylight construction as set forth in claim 2 including a further gasket extending from the operating leaf frame and disposed between the operating leaf frame and covering means.
Claim 5
Dependent Claim
19 words
A skylight construction as set forth in claim 1 including hinge means between the base frame and support frame.
Claim 6
Dependent Claim
50 words
A skylight construction as set forth in claim 4 wherein said hinge means comprises means defining an arcuate channel integral with the base frame profile and means defining an arcuate rib integral with the operating leaf frame retainer said rib adapted to fit in said channel to providing the hinging.
Claim 7
Dependent Claim
35 words
A skylight construction as set forth in claim 5 including a flexible gasket extending from said means defining an arcuate channel and adapted along some sides of the frame means to contact the retaining means.
Claim 8
Dependent Claim
19 words
A skylight construction as set forth in claim 1 wherein said covering means includes at least one plate means.
Claim 9
Dependent Claim
19 words
A skylight construction as set forth in claim 7 wherein said covering means includes a pair of glazing plates.
Claim 10
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 11
Dependent Claim
23 words
A skylight construction as set forth in claim 1 wherein said plastic capping material has a thickness on the order of 0.004 inch.
Claim 12
Dependent Claim

A skylight construction as set forth in claim 1 including a cup-shaped gasket carried by the operating leaf frame and upon which the covering means rests.
Claim 13
Dependent Claim
44 words
A skylight construction as set forth in claim 1 wherein said rigid plastic core has a specific gravity greater than the specific gravity of the capping material and the capping material has a specific gravity greater than the specific gravity of the flexible gasket.
Claim 14
Dependent Claim
47 words
A skylight construction as set forth in claim 12 wherein said rigid plastic has a specific gravity on the order of 1.44, said capping material has a specific gravity on the order of 1.40 and said flexible gasket has a specific gravity on the order of 1.36.
Claim 15
Dependent Claim
66 words
A skylight construction as set forth in claim 1 wherein said flexible gasket has an expanded position when the support frame is moved away from the base frame and has a compressed position when the support frame is moved toward the base frame, and compressed position of said flexible gasket flattening to spread said gasket partially over said top horizontally disposed wall of the base frame.
