Abstract
Abstract The Skylight Escape System of the present invention includes a roof curb which defines an escape opening to the roof therewithin. A pair of spaced guides project upwardly from opposite sides of the curb and a pair of spaced tracks are provided immediately adjacent thereto. A movable skylight which upwardly carries a translucent panel is formed with cooperating slides, which slides are in sliding engagement within the spaced tracks. The application of longitudinally directed forces to portions of the skylight causes the skylight to move along the tracks relative to the curb to expose the opening for building escape purposes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
In a skylight escape system suitable for use with a fixed curb means comprising transverse frame members and longitudinal frame members defining a roof opening, the combination of a pair of tracks mounted directly upon the frame members of the curb means, the tracks being adapted to slidably receive portions of a movable skylight means therewithin, the tracks including raised portions, the raised portions defining respective slide spaces between the tracks and their associated transverse frame member; a skylight means including a translucent panel slidably mounted on the tracks, said skylight means comprising a pair of spaced slides, each said slide respectively slidingly engaging one of said tracks and being positioned within one of said slide spaces to permit the skylight means to slide relative to the curb means, whereby the roof opening may be exposed for use as an escape hatch in case of an emergency.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
53 words
Th skylight escape system of claim 1 wherein the tracks further comprise a pair of spaced guides extending in parallel relationship to the tracks, the said guides extending vertically above and being positioned immediately outwardly from a said track to guide the skylight means when the skylight means is moved along the track.
Claim 4
Dependent Claim
22 words
The skylight escape system of claim 2 wherein each of the guides is affixed respectively to one of said transverse frame members.
Claim 5
Dependent Claim
64 words
The skylight escape system of claim 1 wherein the skylight means further comprise a hinged skirt, said skirt being adapted to depend from below the bottom of the skylight means and to extend over portions of the said curb means, at least part of said skirt being adapted to flex about the hinged portion thereof when the skylight means is moved along the tracks.
Claim 6
Dependent Claim
31 words
The skylight escape system of claim 1 wherein the said slides each comprise a horizontal leg, each leg being of suitable height and width to slide within a said slide space.
Claim 7
Dependent Claim
40 words
The skylight escape system of claim 5 and antifriction means positioned in each slide space, the antifriction means being positioned in said horizontal slide legs, the antifriction means being movable relative to the tracks when the skylight means is moved.
Claim 8
Dependent Claim
42 words
The skylight escape system according to claim 6 wherein the antifriction means are moved within each slide space by its associated slide leg, the antifriction means contacting simultaneously a portion of a track and a portion of a curb transverse frame member.
