Thermal stairway cover
| Details |
Inventors: Hulligan, Jeffrey A.;
Assignee: Colorcraft, Inc. (Memphis, TN)
Primary Examiner: Friedman; Carl D.
Assistant Examiner: Nguyen; Kien
Attorney, Agent or Firm: Body, Vickers & Daniels
A thermal stairway cover is disclosed for insulating a stairway opening containing a pull-down, ceiling stairway leading to an attic. A plate is movable between a first position which closes the cover and reduces heat transfer therethrough and a second position where the cover is open to provide access through the stairway opening to the attic. |
|
DETAILED DESCRIPTION Having thus described the invention, it is claimed: 1.
A thermal cover, comprising: a rectangular frame adapted to be positioned adjacent a support surface having a stairway opening, said frame having side walls and end walls forming an opening therethrough to provide substantially unobstructed access to said stairway opening; a closure plate having a first position to close said opening through said frame for reducing heat transfer therethrough and a second position to open said opening through said frame for providing access therethrough; said closure plate being a sheet of material defined by side edges extending the length of said plate and end edges extending along the width at opposite ends of the plate, said sheet being flexible along its length and relatively rigid through its width; mounting means on said side walls for sliding attachment of said closure plate to said frame so that said plate can be moved between said first and second positions.
2.
A thermal cover as defined in claim 1 wherein said flexible sheet has a corrugated surface.
3.
A thermal cover as defined in claim 2 wherein said corrugated surface includes a plurality of parallel grooves disposed perpendicularly to the side edges.
4.
A thermal cover as defined in claim 1 wherein said closure plate is constructed of plastic.
5.
A thermal cover as defined in claim 1 wherein said mounting means includes first and second grooves, one each along opposite facing surfaces of said side walls, each of said grooves receiving one of the side edges of said plate whereby said plate is slidingly attached to said frame for movement between said first and second positions.
6.
A thermal cover as defined in claim 5 wherein said plate has a handle at one end for moving said plate between said first and second positions and stiffening the plate to keep it within said grooves.
7.
A thermal cover as defined in claim 6 wherein said handle extends slightly less than the width between the first and second side walls.
