Biased wall panel for use with a three-sided alcove

Claim 1

For use with a three-sided alcove having a back wall and adjoining side walls, the planes of the latter being perpendicular to the plane of the back wall, a finishing wall panel for disposition within said alcove comprising a unitary panel integrally molded of durable material having limited flexibility, said panel having a forward or outer face and a rearward face for presentation against said alcove walls, said panel further having a central portion and a pair of side portions, said side portions being normally biased into nonplanar aligned relationship with said central portion extending forwardly therefrom with the planes of said side portions being at an angle of less than 180* and more than 90* to said central portion, the zones between said central portion and said side portions being forwardly concave, said zones defining zones of flexure whereby said side portions may be urged into substantially mutually planar parallel relationship against their normal bias so that when the panel is placed within the alcove the side portions will be urged through their normal bias rearwardly into snug surface abutment against the side walls of said alcove for stabilizing and maintaining said panel in covering relationship therein with said central portion presented against said alcove back wall.
