Abstract
An insulating cover is disclosed for enclosing an opening in a building floor containing a folding stairs which has a pair of tracks mounted adjacent the opening. An inverted box-like structure of sufficient size to cover the opening has sides which fit and are movable in the tracks to enable the box-like structure to be slid horizontally and/or pivoted to cover or expose the openings.

An insulating cover adapted to enclose an opening in a building floor containing a folding stairs, said cover comprising:
- (a) a pair of tracks connected to the building in spaced apart, parallel relationship to each other adjacent said opening,
- (b) an inverted box-like structure of sufficient size to cover said opening and having a top, front, rear, and two side walls, said side walls being respectively positioned and slidably connected in each of said tracks whereby to cover or expose said opening, and
- (c) wherein one of said side walls is pivotally connected in its associated side track and which has a projection at the lower end thereof which extends the length of the said one side wall and which, engages said track to thereby limit the travel of said box-like structure when said box-like structure is pivoted in said track about an axis extending parallel to said track to expose said opening.
An insulating cover enclosing an opening in a building floor containing a folding stairs, said cover comprising:
- (a) a pair of tracks connected to the building in spaced apart, parallel relationship to each other adjacent said opening,
- (b) an inverted box-like structure of sufficient size to cover said opening and having a top, front, rear and two side walls, said side walls being respectively positioned and slidably connected in each of said tracks whereby said box-like structure can be moved at least horizontally to cover or expose said opening, and
- (c) one of said side walls being pivotally connected in its associated track for pivotal movement of said box-like structure about an axis extending parallel said associated track so that said opening can also be covered or exposed by said pivotal movement.
