Doll house
INTRODUCTION 
     This invention relates to a doll house of the knock-down or collapsible type of simplified construction capable of being easily constructed or taken apart. 
     Although there are many types of doll houses which provide recreation and education to children and adults, many of them are of the permanent type presenting problems with shipping and storage. Others, which are of the knock-down type are relatively complicated in construction and require various types of fasteners and locking members to hold the doll house together. These doll houses, for the most part require tools and screws for construction and lack the desired rigidity when constructed. Furthermore, more sturdy types of doll houses, which can be easily knocked-down, are desired by various adult hobbyists. These doll houses are required to have open access to the various floors in order that the hobbyists can set up various furniture arrangements, etc. Interior decorators also find the doll houses useful in planning the furniture arrangements, etc. of rooms. In particular, it has been desirable to have a doll house with a large number of rooms to provide space for a large number of furniture arrangements, etc. A unique design of the present doll house includes first, second and third floor members in combination with side wall members to provide desired additional side rooms for the doll house. 
     Applicant has developed a unique series of doll houses capable of being knocked down as represented by U.S. Pat. Nos. 3,906,659; 3,996,693; 4,021,960 and 4,018,001. 
     BRIEF SUMMARY OF THE INVENTION 
     This invention relates to a doll house of the knock-down or collapsible type of simplified construction, capable of being easily constructed or taken apart for convenient storage. A unique design provides for a front entrance porch and balconies, and a large number of rooms from a minimum number of extended floor and wall panels provided with grooves and slots so that all parts slide together easily and support one another. The assembling of the doll house is easily done in minutes and does not require any tools or screws. Once assembled, all the parts are locked together by the insertion of several small pegs between adjacent parts to provide a rigid structure. 
     It is, therefore, an object of this invention to provide a doll house having a unique construction design capable of being easily assembled or constructed without special skill or the use of tools and fasteners, which can be easily disassembled or knocked-down for storage or transport purposes. 
     Another object of this invention is to provide a doll house that is relatively rigid and sturdy in construction when assembled requiring only simple pegs for holding the assembled house together. 
     A further object of this invention is to provide a doll house constructed from a novel arrangement of floor and wall panels provided with grooves and slots whereby assembly or disassembly of the doll house is facilitated. 
     Another object of this invention is to provide a novel floor construction for a doll house whereby additional rooms are provided for the doll house. 
     Another object of this invention is to provide a novel front door, porch and balcony construction in the front wall of the doll house. 
     A still further object of this invention is to provide novel, unique window constructions in the walls of the doll house.
