Abstract
Abstract This invention relates to the field of packaging and fuel saving devices and to articles and methods therefor. One embodiment comprises a shipping container for unitized attic stairs. The container is made from rigid plastic foam material which has good thermal insulating characteristics and is so dimensioned as to fit snugly on the peripheral frame of the stair unit after it has been installed. As such, it provides a removeable thermal barrier for the stair-well between an attic and the living quarters of a home. Other embodiments include a matching container member made from similar material which may be utilized in conjunction with the first member so as to further enhance the fuel saving characteristics of the finished installation.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
139 words
For use in connection with a unitized building component having a peripheral support frame, a structural member made from material which is structurally rigid and of low thermal transmissivity, said structural member being bottomless, having a top, and having side walls, the outside surfaces in the region of the exposed bottom edges of which are configured substantially as are the outside surfaces of the peripheral support frame of the component with which said member is to be associated, in the region of the top surfaces of said support frame, whereby said structural member may be positioned with the exposed bottom edges of its side walls juxtaposed to the top surfaces of said peripheral support frame, for use as a packaging device for said component and for use as a removable insulation device for use with said component after installation.
Claim 2
Dependent Claim
139 words
For use in connection with a unitized building component having a peripheral support frame, a structural member made from material which is structurally rigid and of low thermal transmissivity, said structural member being bottomless, having a top, and having side walls, the outside surfaces in the region of the exposed bottom edges of which are configured substantially as are the outside surfaces of the peripheral support frame of the component with which said member is to be associated, in the region of the top surfaces of said support frame, whereby said structural member may be positioned with the exposed bottom edges of its side walls juxtaposed to the top surfaces of said peripheral support frame, for use as a packaging device for said component and for use as a removable insulation device for use with said component after installation.
Claim 3
Dependent Claim
118 words
The structural member described in claim 1 and a second member made from material which is strucurally rigid and of low thermal transmissivity, which is topless, has a floor, and has side walls, the inner surfaces of which conform substantially with the outer surfaces of the side walls of said structural member is positioned within said second member with the floor of said second member substantially parallel to the top of said structural member, whereby said second member may be positioned about the outer edges of the sides of said structural member and of said component for use as a packaging device, and may be inverted for use as a removeable insulation device with said component after installation.
Claim 4
Dependent Claim
71 words
The device described in claim 1 wherein the outer surfaces of all of the side walls of said structural member are substantially co-planar with the outer surfaces of the peripheral support frame of said component when the exposed edges of each are juxtaposed to the exposed edges of the other with the outer surfaces of two adjacent of the sidewalls one co-planar with two adjacent of the sidewalls of the other.
Claim 5
Dependent Claim
71 words
The device described in claim 2 wherein the outer surfaces of all of the side walls of said structural member are substantially co-planar with the outer surfaces of the peripheral support frame of said component when the exposed edges of each are juxtaposed to the exposed edges of the other with the outer surfaces of two adjacent of the sidewalls one co-planar with two adjacent of the sidewalls of the other.
Claim 6
Independent Claim
20 words
The device described in claims 1, 2, 3, or 4 adapted for use with a pre-fabricated lowerable attic stair unit.
Claim 7
Independent Claim
159 words
A method of insulating a pre-fabricated building component having a peripheral support frame comprising the steps of positioning atop said component a structural member made from material which is structurally rigid and of low thermal transmissivity and has a top and an open bottom, and side walls, the outside surfaces in the region of the exposed bottom edges of which are configured substantially as are the outside surfaces of said peripheral support frame in the region of the top surfaces thereof, and positioning inverted atop said structural member a second member made from material which is structurally rigid and of low thermal transmissivity, and has an open top and a bottom, and side walls, the inner surfaces of which conform substantially with the outer surfaces of the side walls of said structural member when said structural member is positioned within said second member with the floor of said second member substantially parallel to the top of said structural member.
Claim 8
Independent Claim
159 words
A method of insulating a pre-fabricated building component having a peripheral support frame comprising the steps of positioning atop said component a structural member made from material which is structurally rigid and of low thermal transmissivity and has a top and an open bottom, and side walls, the outside surfaces in the region of the exposed bottom edges of which are configured substantially as are the outside surfaces of said peripheral support frame in the region of the top surfaces thereof, and positioning inverted atop said structural member a second member made from material which is structurally rigid and of low thermal transmissivity, and has an open top and a bottom, and side walls, the inner surfaces of which conform substantially with the outer surfaces of the side walls of said structural member when said structural member is positioned within said second member with the floor of said second member substantially parallel to the top of said structural member.
