Abstract: An improved double hung access opening cover is disclosed wherein a fixed frame borders the opening, a movable frame is hingedly attached to the fixed frame on one side of the opening and to the cover therefor on the other side, and wherein a crossframe element is hingedly attached to the cover on the same side of the opening where the movable frame is attached to the fixed frame about a hinge pin axis in common with the latter and to the fixed frame on the other side thereof where the movable frame is attached to the cover about a hinge axis in common therewith. These elements can, by way of example, be arranged and shaped to define a cabinet having independently accessible compartments positioned one behind the other or, in another form, a door which when opened from one side uncovers the doorway and from the other provides access to a closet.

Abstract: This invention relates to an improved auxiliary frame assembly for use between the fixed frame bordering an access opening and the cover therefor which hinges the latter to be opened from either side, such assembly being characterized by an inner movable frame hingedly attached on one side to the fixed frame and on the other side to the access opening cover, an outer movable frame bordering the inner one movable independently of the latter, this outer movable frame being hingedly attached to the fixed frame on the same side of the access opening at which the inner frame is attached to the cover, and the outer movable frame being hingedly attached to the cover on the same side of the access opening at which the inner movable frame is hinged to the fixed one, the outer movable frame and access opening cover cooperating to define a unitary subassembly hinged on the side where the inner frame is hinged to the fixed frame, and the inner movable frame and access opening cover cooperating to define a second subassem
