Abstract

A flexible cover overlies portions of the central panel whereby the base frame and cover capture the panel therebetween.
Claims8
A filler for an opening through a structure comprising:
- A) a flexible panel, and
- B) a planar base frame with an opening therethrough for supporting the panel, said base frame being composed of a closed cell foam material with density, memory and flexibility characteristics that allow the frame to be folded and to relax to a substantially planar configuration, and
- C) a cover having a density that is less than the density of said planar base frame material with an opening therethrough coextensive with the opening through said base frame whereby said cover is at least as flexible as said planar base frame and whereby said base frame and cover support said panel by capturing the edges thereof.
