TOY STRUCTURE Filed April 7, 1957 4 Sheet-Sheet 4 Patented Mar. 29, 1938 i TOY STRUCTURE Donald M. Warren, west Lafayette, 1 m; Application April .7. 1931, sci-layup. 135,358 r 6 Claims. (01. 4s-21)' This invention relates to improvements in a toy structure and vmore particularly to improvements in the construction of such toys as paperboard doll houses and other forms of toy buildingsp The invention also contemplates improve-'- .ments adaptable to the constructionof toy articles which represent only a single room.

. The main-objects of the invention are to provide astructure which may be sold in a collapsed conditionvand which may be easily and quickly set up into a house or room by a young child; to provide a structure which when set up, is rigid and will remain in set up condition and the parts of which 1 will not tend to come apart and collapse; to provide a structure which may be collapsed to a flattened condition in which it may be conveniently and practicably packaged in an'envelope instead of the usual more expensive box; 'tdprovide a structure which may be made economically and at low cost so as to be adapted to beretailed at very low prices; and in general,

. it is theqobject of the invention to provide an improved toy structure of the class described. Other objects and advantages of the invention. will be understood by'reference to the following specification and accompanying drawings (4 sheets), wherein there is illustrated a toy structure embodying a selected form of the invention and certain modifications thereof.

Fig. 10 is 'an exploded perspective of. acorner portion of the structure shown in Fig. 9, and 5 Referring now to .therdrawings the structure shown in Figs. '1 to ,3 '-inclusive.embodies a base member l5.which is preferably formed oi paperboard of such thickness. as will affgord the de- 10 sired stifiness and strength. The base member, a a

when in collapsed condition as shown in Fig. 3, is provided with score lines such as indicated at l6 which are. spaced inwardly. from and are disposed parallel with the respectively adjacent. 15 free edge portions of the blanla, The marginal portidns of the blank outwardly of the fold lines l6 are adapted to be foldeddownwardly-seas to constitute flanges l1, l1 depending-from the edges of the base which are then defined by As indicated i lri ag l the said fold lines l6. certain of 'said marginal portions are separatedQv from adjacent marginal portions and. from the body of the which. permit the various flange portionstocb folded downwardly as explained. I J

For purposes which will presently fappeinftongues where desired, are provided on theedg es R of the base membenthe said tongues beihgcut out of the respective marginal or flange-form 0 The tongueaare. formed by slit-' i ing portions. ting the said flange-forming portions as, indicated at IS, the said slitting being continuous around three sides of the tonguesoas to define tongues which project .edgewise from ,thernain' 5 in continuation of the normal plane thereof. It will be observed that the fold lines i are interrupted across the widths of the tongues so that-when the flanges are folded body of the base downwardly, the tongues' remainin theirfnormalgo I fiatwise position relative. to the main body of, the base. The various tongues which arefonned by being cut out of the foldable marginal -portions are designated 20. Similar tongues 2!, 21

are formed on the ends of one-of the flanges.

II which in this instance cQnstitutes the rear' edge of the structure. As clearly indicated-,in Fig. 3, the tongues 2i, are of somewhat less, width than the tongues 20, thisbeing incident to the limited width of the foldable-marginal .150

portions on which said tongues H are formed. I As shown in Fig. 1, the structure. embodies a mainhouse portion and an auxiliary house portion 23 which projects from one end wall of the structure.

.Fig. 11 is a section on the -line-l l- |I of Fig.9. I

base'by slits such asdndicatedat l8 1 v 52 I The base member I! constiu tutes the floor element for the structure and, as shown, it is equipped with an integral extension which constitutes a floor portion for the said auxiliary or bay window portion 23.

. At one end of the structure there is an end wall 24 which is provided with a pair of openings 25, 25 adapted to receive the tongues 20 which project from the adjacent end of the base. The

tongue and opening structure is preferably of the type indicated which includes tongues humped somewhat intermediate their lengths so that when they are projected through the openings they tend to have a snap locking effect for holding the wall member against the end of the base. The lower marginal portion of the end wall 24, i. e. that portion below the upper edges of the openings 25, overlaps the depending flange H on the end of the base. By reason of the indicated anchorage of the end wall to the base, the wall will be effective to maintain the flange in its depending folded condition against the inherent tendency thereof to unfold to the initial flat form of the blankof which the base is formed.

The 'end wall 24 is further provided with an opening such as indicated at 26 for receiving the 7 end tongueZl of the rear edge flange. By thus connecting the rear flange with the end wall,

the rear flange is also held in its downwardly folded-position, even thoughno rear wall is provided'in overlapping relation to the said rear flange.

At the other end of the house structure, an end wall'21 is provided, the latter being provided'with a slit as indicated at 28 and with fold lines 29, 29 at a suitable elevation from the lower edge of the end wall 21, so as to permit the end wall portions 30, 30 respectively located intermediate the slit 28 and the opposite fold lines 29, 29,to be folded outwardly to fit against the depending flange portions I! of the base, while 1 the frontand rear end portions of the end wall, I i. e; those portions outwardly of the fold lines "29, 29 flt against the end flanges IT of the base. As indicated, the end wall 21 is provided with suitable openings for engaging the various tongues 20, for anchoring the end wall to the base. The

. resr end of the end wall 21 is also provided with an opening for receiving the adjacent end tongue 2| for the purpose already indicated. The extreme-end portion il of the bay window portion of the base receives a separate end wall 3| which is suitably apertured to receive thetongue 20.

The wall 3| is further locked in place by beingprovided with'tongues such as indicated at 32, 32

which interlock with suitable openings such as indicated at 33 in the respective wall portions 30.

- A roof element 34 properly shaped and equipped with fold lines to permit its bending to the form indicated, covers the upper end of the auxiliary portion 23 of the structure, and it is secured in place by tongue and opening connections with the walls of the auxiliary structure and the end wall 21 substantially as indicated.

It willbe understood, of course, that the various wall elements and roof elements heretofore referred to and those which will presently be "mentioned, are preferably formed of suitable grades of paper-board and that the fold lines mentioned may beformed by creasing or scoring or in any other approved manner.

"Ifo improve the appearance of the structure, it is equipped with a front wall having an offset as shown. One front wall'portion is designated 35, the same being equipped with a suitable opening 25 to receive the base tongue 20. It is also provided with other openings such as indicated at 36 and 31, those indicated at 36 being adapted to receive tongues such as 38 which extend edgewise from the end wall 21. The length of the front wall portion is preferably somewhat in excess of the length of the corresponding base flange portion, so that the openings ,36 and 31 may each be spaced inwardly from the adjacent ends of the wall part. To permit the inner end of the wall 35 to be positioned against-the base flange II, the base is provided with a notch 39 in the edge portion 40 of the base, the said notch extending substantially in alignment with the inwardly recessed edge portion 4| of the base (Fig. 2). The notch 39 receives an end portion of the wall 35 and has the desirable effect of cooperating with the tongue 20 on said edge 4| to hold the wall 35 in assembled relation with the wall portion 35, extends outwardly therefrom. The inner edge of the wall portion 46is equipped with tongues such as indicated at 47 for entering the openings 31 in the wall portion 35 to thereby lock said wall portion 46 to'the wall portion 35. v A roof member 48 of generally rectangular form and provided with a'lengthwise extending fold line is adapted to be folded -to flt the peaked upper ends of the end walls. The said roof member may be fastened in place by the provision of openings such as indicated at 49 for receiving tongues such as 50 which project upwardly from the said peaked upper edges of the end walls 24 and 21. The front edge of the roof may be slotted at 5| to embrace the thickness of the wall portion and whereby the said wallportion is more firmly held against unfolding movement.

It will, of course, be understood that the various folded parts have a normal tendency to spring back from their fully folded position (usually at right angles to the portions from which they extend) to initial flat position. This is true even though the fold lines be made by slitting the paper-board stock part way through its thickness which produces a sharp fold which enhances the appearance of the structure. It will be also understood that the various wall, the roof and the floor parts of the structure, may be suitably embossed to represent doors, windows, brick, shingling, interior trim and other designs appropriate to the various portions of the structure.

The described structure when set up has been found to be surprisingly rigid and stable. It has the desirable advantage that when disassembled the base may be unfolded to the flat condition illustrated in Fig. 3, whereupon the various other parts of the structure may be stacked on top of the flattened base preparatory to wrapping or packaging, for example in a conventional envelope. The interconnection of the various walls with each other and with the roof structure serves to prevent the said walls from waveringlinwardly or outwardly, so that they are rigidly maintained in the substantially vertical position desired. Due to their effective attachment to the edges of the base, the lower marginal portions of the n are of such width that'whe n the structural? placed on a table surface or floor, they rest on the same so as toreliev e the wall portions of any duty of supporting the structure fromflthe flanges l1 substantially as described inconnection with Fig. 3, but the rear flange ll is not provided with end tongues such as the tongues 2i. Instead, tongues such as indicatedat 52 are provided near the ends of the base, substantially in the same manner that the tongues 20 are provided, and the end wall 53 is provided with a foldable rear edge portion 54 which is adapted to be folded around the back edge of the structure to overlap the adjacent end portion of therear flange H The said wall portion 54 is equipped with an opening 55 for receiving the tongue 52 to lock the wall in said overlapping relation to the The structure shown in Figs. 7 and 8 embodies still another detail of construction for maintaining the base flanges in their folded condition. In

, this form of construction the endv flanges l 1 are provided with end extensions I1 and the latter are' notched as indicatedat 56, the said 'notcheshaving their inner edges, in alignment flange extension I! so as to overlap the adjacent end portion of the rear flange ll of the base. When so assembled the rear wall flange B is prevented by the overlapping upper portion of the flange end extension l1 from unfolding. Hence, the rear flange ll of the base iseffectively maintained in its folded condition. A front wall 60 is provided with a notch 5| in its lower edge for cooperating with the notch or slot 56 in thefront end extension ll so as to permit the wall 60 to be assembled with the base so that the lower marginal portion of the wall overlaps the front flange H. The wall 60 and front edge of the end wall 51 may additionally be equipped with one ormore tongue and opening connections such as indi cated. It will be seen that the interlocking notched arrangement shown in Figs. '7 and 8 effectively locks all of the base flanges in their folded position and provides means whereby the wallsof the structure may be connected to the base without the use of connections formed by tongues such as 20 and openings such as 25. However, it is preferred that a few of such tongue and opening connections be provided so as to prevent the base structure from dropping out of the wall structure the house is lifted by its walls and the interlocking slots happen to be a loose flt as they may become after the structure has been assembled and disassembled a considerable number of times.

i In Figs. 9 to 11, there is shown a structure in which the base l5 has its end flaps I'l provided with tongues such as 2i and its front and rear flaps ll and l1 provided with suitable openings 3 error receivingthe said end tongues 21 when the flanges are folded totheir operative position "as illustrated. The end wall part 63 is suitably notched or'recessedas indicated at 64 at the lower ends of its front and rearedges to flt'around the end extensionsof thebase flanges I! and Il and it is further provided with a'forwardly extending tongue 65 whichhas its lower edge 86 substantially flat and adapted to extend over the upper edge of theadjacentend extension of the front flap i1 The front wall is provided with openingssuch as indicated at 6B and 69 for r-" spectively receiving the tongues 2l'and 55 to lock the front wall to the end walland to the base as will be clearly understood. For some purposes it is preferable that the base member l5 be provided with extra wide flanges so as to elevate the normal floor level considerably abov'the surface at the bottom of the structure, would have to be so far removed from the loweredge of-the wall that there might be an objectionable tendency of the wall to spread from the front flange of the base structure. In order to maintain the tongue and opening connection at the lowest practical locationfthedowermost tongue 41 in Fig. 1 may be'replaced by a tongue such as indicated at 41 in Figs-{9 and 11. The tongue 41 may be described as a half tongue and the opening 3'! for receiving 'siichtongue is'modified high speed and almost wholly automatically.

Hence, the cost of production is maintained low. Also, as already indicated, since the various parts may be collapsed to flat condition they may be conveniently and neatly packaged either by wrapping or by insertion in an envelope, thereby eliminating the need for any form of box such as has been more or less of a necessity with present day conventional constructions.

Changes in the described constructions may be made without departing from the spirit of the invention, the scope of which should be determined by reference to the following claims, the same being construed as broadly as possible consistent with the state of the art.
