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.
