Abstract
Abstract A collapsible play structure, such as a doll house, is formed with a base unit having storage means, such as drawers, located therein. A pair of opposed parallel and upright side wall panels, are pivotly mounted to the base, and a plurality or horizontal panels are pivotly mounted to and between the side walls to form the floors and ceilings of the unit. A front wall panel extends upwardly between the side walls and is pivotly attached to the front edge of one of the horizontal panels. Lock means are provided on the horizontal panels and on the front wall panel to removably join the horizontal and front wall panels together to permit the structure to be retained in the upright and upstanding position.
