Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
206 words
The combination with a frame for holding a single pane of glass of: An adaptive element comprising an elongated base member having an elongated rail depending from one side thereof and perpendicular to the plane thereof, said rail being inserted in said frame in lieu of glass, a pair of elongated guides - one adjacent each edge of said base - depending from said base in the opposite direction from said rail and at a perpendicular relationship to the base, said guides being provided with serrations on their surfaces facing one another, and a pair of Lshaped projections depending from said base in the same direction as said side members, with the bases of said L-shaped members facing one another in a mirror image of such manner as to form a T-shaped cavity intermediate said members; mastic material partially filling the space between said side members; two panes of glass within said side members, one side of each pane of glass being adjacent the said serrations, the other sides of said panes of glass being at a spaced relationship from one another; an elongated hollow member containiNg a desicant extending the length of said panes of glass and adjacent their edges in contact with said mastic.
Claim 2
Dependent Claim
206 words
The combination with a frame for holding a single pane of glass of: An adaptive element comprising an elongated base member having an elongated rail depending from one side thereof and perpendicular to the plane thereof, said rail being inserted in said frame in lieu of glass, a pair of elongated guides - one adjacent each edge of said base - depending from said base in the opposite direction from said rail and at a perpendicular relationship to the base, said guides being provided with serrations on their surfaces facing one another, and a pair of Lshaped projections depending from said base in the same direction as said side members, with the bases of said L-shaped members facing one another in a mirror image of such manner as to form a T-shaped cavity intermediate said members; mastic material partially filling the space between said side members; two panes of glass within said side members, one side of each pane of glass being adjacent the said serrations, the other sides of said panes of glass being at a spaced relationship from one another; an elongated hollow member containiNg a desicant extending the length of said panes of glass and adjacent their edges in contact with said mastic.
Claim 3
Dependent Claim
80 words
The device of claim 1 in which there are four of said adaptive elements, one extending the length of each edge of a rectangular single glass frame, with the rail of each adaptive member inserted within such single glass frame member, and in which an angular shaped bracket is inserted a distance in to the T-shaped cavity of adjoining adaptive elements, which adaptive elements are mitered at their corners in such manner that the said brackets hold the corners together.
Claim 4
Dependent Claim
60 words
The device of claim 2 in which the rail of each adaptive element is adjacent one edge of said base with the remainder of said base over-hanging from said rail, in such manner that when mounted within the single pane glass frame, one side of said single pane glass frame will be flush with one side of said adaptive elements.
Claim 5
Dependent Claim
20 words
The device of claim 2 in which each of said rails is located in the center of said base member.
