Insulating cover for attic stair opening

DETAILED DESCRIPTION OF THE INVENTION With further reference to the drawings, the attic stair insulating cover of the present invention is shown therein and indicated generally by the numeral 10.
Insulating cover 10 includes a main insulating member 12 that is positionable over an attic stair opening, as shown in FIG.
1.
Main insulating member 12 is comprised of attachable first and second insulating sections 14 and 16 that are shown in a disassembled position in FIG.
2.
First and second insulating sections 14 and 16 are blow molded with an insulating material having sufficient strength to permit attachments to be integrally molded to the main insulating member 12.
In the preferred embodiment, the insulating material used is polyurethane.
Insulating sections 14 and 16 each include a closed top 18, an open bottom 20, closed side walls 22 and an open side wall 24.
Located along each open side wall 24 is an interface edge 26 designed such that insulating sections 14 and 16 can be fixedly attached together.
Interface edge 26 includes a projected section 28 and an indented section 30.
Molded into closed top 18 and a closed side wall 22 are inserts cups 32 that open at projected section 28 of interface edge 26.
Mating plugs 34 are likewise molded into the closed top 18 and a closed side wall 22 and extend outwardly from the indented section 30 of interface edge 26.
Insert cups 32 and mating plugs 34 provide an attachment means for attaching together first insulating section 14 and second insulating section 16.
When first and second insulating sections 14 and 16 are orientated as generally shown in FIG.
2, the first and second insulating sections 14 and 16 can be pressed together such that mating plugs 34 are inserted into insert cups 32.
In this manner, the indented section 30 and projected section 28 of the first insulating section 14 are mated to the opposing projected section 28 and indented section 30 of second insulating section 16.
Located at the lower portion of closed side walls 22 is a bottom contact edge 36
