Abstract
Abstract A skylight panel of fiberglass or other translucent material is integrated into a metal standing rib roof without loss of structural integrity in the roof system. The skylight panel is suspended in the roof system by a pair of formed suspension channels without the use of rivets or other like fasteners. The skylight panel is relieved of direct stresses caused by expansion and contraction of the roof system, and is protected from abrasion and wear caused by sliding contact with purlins or other metal parts. The skylight mounting means is characterized by simplicity and economy and is effectively sealed against leakage.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
142 words
In a standing rib metal roof having multiple side-by-side metal roof panels and intervening roof panel support clips for attaching the roof panels to purlins and cap strips for locking the opposing side walls of adjacent roof panels to said intervening clips, the improvement which comprises a skylight panel disposed between one pair of said clips in the space normally occupied by a metal roof panel, and a pair of side metal suspension channels mounted on opposite side walls of the skylight panel and floatingly supporting the skylight panel for restricted movements relative to said suspension channels and other components of the standing rib roof, and said side metal suspension channels configured for engagement with said support clips and said cap strips in substantially the same manner that the metal roof panels of the standing rib roof are engaged with said clips.
Claim 2
Dependent Claim
142 words

Claim 3
Dependent Claim
57 words
In a standing rib metal roof as defined in claim 1, and said skylight panel and said roof panels being of channel formation and sealant strips applied over the upper edges of the side web of said skylight panel and being intervened with opposite faces of said side webs and opposing portions of said metal suspension channels.
Claim 4
Dependent Claim
106 words
In a standing rib metal roof as defined in claim 2, and each of said side metal suspension channels including a bottom web engaging beneath the bottom wall of the skylight panel along one longitudinal edge portion thereof and further including a top web engageable below a locator flange on the top of each clip, and an upper right angular leg extension dependent from said top web and lying on the interior side of one side web of the skylight panel to snugly engage such side web and the adjacent sealant strip between said leg extension and the main vertical web of said metal suspension channel.
Claim 5
Dependent Claim
44 words
In a standing rib metal roof as defined in claim 3, and flange guard extensions on the bottom web and leg extension of said suspension channel in diverging relationship with the walls of the skylight panel to prevent metal edge contact with said walls.
Claim 6
Dependent Claim
20 words
In a standing rib metal roof as defined in claim 4, and said skylight panel being formed of translucent plastics.
Claim 7
Dependent Claim
19 words
In a standing rib metal roof as defined in claim 5, and said skylight panel being a fiberglass panel.
Claim 8
Dependent Claim
109 words
A skylight panel unit for placement in a standing rib metal roof in the space usually occupied by one metal roof panel between adjacent roof panel attaching clips, said skylight panel unit comprising a channel cross section skylight panel including side webs and a bottom web, and a pair of opposing side suspension metal channels for said skylight panel adapted to support the same floatingly on and between a pair of attaching clips of the standing rib metal roof, and said side suspension metal channels configured for engagement with said clips in the same manner that the metal roof panels engage the clips in said standing rib metal roof.
Claim 9
Dependent Claim
109 words
A skylight panel unit for placement in a standing rib metal roof in the space usually occupied by one metal roof panel between adjacent roof panel attaching clips, said skylight panel unit comprising a channel cross section skylight panel including side webs and a bottom web, and a pair of opposing side suspension metal channels for said skylight panel adapted to support the same floatingly on and between a pair of attaching clips of the standing rib metal roof, and said side suspension metal channels configured for engagement with said clips in the same manner that the metal roof panels engage the clips in said standing rib metal roof.
Claim 10
Dependent Claim
41 words
A skylight panel unit as defined in claim 7, and sealant strips disposed about the top longitudinal edges of the side webs of said skylight panel and intervened with the side webs and formed portions of said side suspension metal channels.
Claim 11
Dependent Claim
43 words
A skylight panel unit as defined in claim 8, and said formed portions consisting of top lateral extensions on said suspension channels and dependent right angle leg extensions on said lateral extensions and lying inwardly of said side webs of the skylight panel.
Claim 12
Dependent Claim
17 words
A skylight panel unit as defined in claim 7, and said skylight panel formed of translucent plastics.
