Doll house
BACKGROUND OF THE INVENTION 
     This invention relates to a doll house or toy house of the knock-down or collapsible type having a pleasing front porch with columns design and simplified construction, capable of being easily constructed or taken apart. 
     There have been developed various types of doll houses to provide recreation and education to children and adults. Many of these doll houses are of the permanent type presenting problems with respect to 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, a doll house having a porch with columns has not been easy heretofore to construct in a knock-down type. 
     BRIEF SUMMARY OF THE INVENTION 
     Generally, the present invention provides a unique design for a knock-down construction of a doll house. The doll house is constructed with a unique porch roof with columns and a small number of panels provided with grooves and slots so that all parts of the house slide together easily and support one another. Columns are provided in the front of the house which are easily assembled with a unique porch roof. The entire doll house assembles easily in minutes using no tools or screws, and once assembled, all the parts are locked tightly together to provide a rigid, sturdy structure by the simple insertion of several small pegs strategically arranged with respect to the structure of the doll house. 
     It is, therefore, an object of this invention to provide a doll house having a unique porch and columns construction design capable of being easily constructed without special skill or the use of tools and fasteners, and 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 novel arrangement of panels provided with grooves and slots whereby construction or disassembly of the doll house is facilitated. 
     Another object of this invention is to provide a novel column construction with a porch for a doll house whereby the columns are held in place between a porch roof and the first floor at the front of the doll house. 
     Another object of this invention is to provide a novel rear transparent viewing panel which is adapted to be installed at the rear of the doll house through which the contents of the doll house can be viewed and protected. 
     Other objects, advantages and features of the invention will become apparent from the following detailed description of a preferred embodiment of the invention when considered with the accompanying drawings.

     The rear roof member 34 is installed by inserting the slots 342 and 343 of edge 341 of the beam 340 in slots 246 and 266 of the left and right side wall, respectively. The inner surface of the roof 34 rests on the rear slanted edges 244 and 264 of the left and right side walls, respectively. Similarly, the slots 362 and 363 of edge 361 of the front roof beam 360 are installed in slots 246 and 266, and the roof member 36 rests on front slanted edges 246 and 265 of the left and right side walls, respectively. The two beams 340 and 360 abut each other. 
     Porch roof 29 is installed on the outside of the front wall 30 along with the columns as follows (see FIGS. 3-6). The porch roof 29 is first turned upside-down and each column is engaged in the beam 291. Column 40, for example, is engaged by inserting peg 400 in hole 292d of beam 291. Similarly, columns 41-43 are engaged in beam 291 in holes 292c, 292b and 292a, respectively. The porch roof and columns are righted and longitudinal T-portion 297 of porch beam 296 is inserted in longitudinal slot 309 of beam 308 of front wall 30. At the same time, the bottom pegs of the columns are inserted in the hole along the front of the floor 22, e.g. peg 403 of column 40 is inserted in hole 226d and similarly bottom pegs of columns 41-43 are each inserted in holes 226c-226a, respectively. 
     The rails 297 and 298 are next inserted between the installed columns as shown in FIGS. 5 and 6. The post 40a of column 40 is rotated so that protruding pegs 401 and 402 face towards column 41. Similarly post 41a of column 41 is rotated so that the protruding pegs 411 and 412 face towards column 40. Porch rail 84 is mounted by engaging underside grooves 841 and 842 of rail 84 on pegs 401 and 402, respectively, of post 40. 
     Similarly, underside grooves 843 and 844 of the rail 84 engage pegs 411 and 412 of post 41a. Rail 86 is similarly mounted between the posts of columns 42 and 43. 
     The placement of the pegs for holding the doll house together is uniquely designed for easy assembly as well as providing the rigidity required for the doll house. For the most part, a triangular arrangement is provided for the pegs. Thus, pegs 66, 68 and 69; pegs 64, 69 and 68, 65, 66 and 71; 63, 68, 69 and 71, etc., all form a triangular construction. 
     As shown in FIGS. 2 and 3, a unitary staircase 62 is installed between the first and second floor against intermediate wall 28. The bottom 620 of the staircase rests on the first floor 22 and an upper edge 621 extends through the stair well 320 and rests on ledge 329 of floor 32. A protective L-shaped handrail 622 is also provided around the stair well. 
     The doll house is knocked-down or disassembled by reversing the above procedure. The unique and novel design provides the benefits of knock-down construction. The use of grooves and slots provide means for easily sliding the various parts together, which support one another. The doll house is rigid in construction and all parts are held together tightly by the simple insertion of a relatively small member of strategically arranged small pegs. When disassembled, the parts of the doll house can be stacked together for easy storage or shipment. 
     FIGS. 14-16 disclose an optional novel transparent panel 90 is provided for installation across the open rear of the doll house. The panel 90 comprises a transparent pane 904 of glass, plexiglass, tec., L-shaped members 901 and 902 secured by suitable means on each side, a member 903 secured across the top, and peg hole 905 in L-shaped member 902 and a similar peg hole (not shown) in member 901. 
     Panel 90 is installed across the rear of the assembled doll house (shown in FIG. 15 with the roof panels 34 and 36 removed to better depict panel 90 as installed) by placing edge 906 on the rear of floor 22. The panel is placed flush against the rear edges of side walls 24 and 26, whereby L-shaped members 901 and 902 are engaged around the outside edges of walls 24 and 26, respectively. Wall 26 is provided with peg hole 908 and L-shaped member 902 is provided with peg hole 905. A peg 907 is inserted in holes 905 and 908. Similarly, a peg (not shown) is inserted in holes (not shown) in L-shaped member 901 and wall 24. The two pegs hold the panel 90 securely across the rear of the doll house. 
     The panel 90 provides protection for the inside of the doll house which can contain valuable miniature furniture collections on display. In addition, the panel being transparent, one can easily view the contents of the doll house. 
     Although the doll house of this invention has been disclosed heretofore as the preferred embodiment, wherein four rooms are available by using the one intermediate wall member 28, it is understood that the doll house can be constructed to contain more than one intermediate wall member thus providing sic or more rooms. Furthermore, the number of columns used can be more or less than four as shown in the preferred embodiment. 
     The above description of the invention is deemed to be the most practical and efficient embodiment and it should be understood that the invention is not limited to such embodiments as heretofore indicated as there could be further changes made in the arrangements, disposition and form of the parts without departing from the principle of the present invention within the scope of the accompanying claims.
