As shown in FIGS. 2 and 3, a design representing the interior of each room is printed on the inner surfaces of the first to fourth components 1A to 1D. In addition, the part around which the design 6 representing the door is applied is partly punched out, and is rotatable in the horizontal direction. Further, on the inner surfaces of the first to fourth constituent members 1A to 1D, a three-dimensional interior member formed by attaching another member 7 is provided. When the three-dimensional picture book is folded, these interior materials are bent flat and sandwiched between the first side wall 2 and the second side wall 3.

[0008] The first side wall 2 and the fourth side wall 1 of the first component 1A.
Each of the second side walls 3 of the component member 1D also serves as a cover, and although not shown, a trade name, a design, a precautionary note, a manufacturer name, etc. are printed on these outer surfaces. Also,
Velvet-type fastener loops 8A to 8C are provided at the upper right and lower ends and the center of the outer surface of the first side wall 2 of the first component 1A.
Hook-shaped members 9A and 9B of a velvet type fastener are provided at upper and lower left and right ends of the outer surface of the second side wall 3 of D.

Also, the second side wall 3 of the fourth component 1D
A strip 10 is attached to the center of the right end of the outer surface so as to protrude laterally. This strip 10
Can be bent in a U-shape so as to sandwich right end portions of the first to fourth constituent members 1A to 1D, and a hook-shaped member 9C of a velvet type fastener is provided on an inner surface of a tip portion. I have. When this hook-shaped member 9C is engaged with the loop-shaped member 8C of the first side wall 2 of the first component 1A as shown in FIG. 1, the opening of the three-dimensional picture book is prevented, and the book is folded into a booklet. State is maintained.

Next, a method of assembling the three-dimensional picture book will be described. First, the strip 1 engaged with the loop-shaped member 8C
Remove 0. Then, as shown in FIG. 2, one hand holds the first side wall 2 of the first component 1A, and the other hand holds the second side wall 3 of the fourth component 1D. Are rotated in a direction approaching each other, the angle between the first side wall 2 and the second side wall 3 of the first to fourth component members 1A to 1D starts to open and the bottom wall 4 starts to fall downward .

When the first side wall 2 of the first component 1A and the second side wall 3 of the fourth component 1D are opened by about 360 ° so as to face each other, as shown in FIGS. The first and second side walls 3 of the first to fourth constituent members 1A, 1B, 1C, and 1D form substantially 90 °, and the bottom wall 4 is formed of the first and second constituent members.
And a substantially 90 ° angle with the side walls 2, 3, thereby forming first to fourth spaces S 1, S 2, S 3, S 4 partitioned from each other. Loop-shaped members 8A, 8C are replaced with hook-shaped members 9A,
By engaging with 9B, the first side wall 2 of the first component 1A and the second side wall 3 of the fourth component 1D are fixed to each other, and this state is maintained.

The first one of the simulated dwellings thus formed is
By placing a doll or the like on the bottom wall 4 of the fourth to fourth spaces S1 to S4 and performing “outdoor play”, the infant can learn the structure and functions of the house while having fun.

[0013]

However, in the three-dimensional picture book as described above, in the assembled state, the bottom wall 4 is subjected to a force to bend in a mountain shape along the mountain fold line L1. 4 has a problem that it is bent in a mountain shape, and it is difficult to place objects such as dolls.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. 7 is a perspective view of an assembled state of the three-dimensional picture book of the present embodiment, FIG. 8 is a plan view of FIG.
9 is a development view of first and second components forming the three-dimensional picture book of FIG. 7, FIG. 10 is a development view of third and fourth components forming the three-dimensional picture book of FIG. 7, and FIG. FIG. 8 is a sectional view taken along line XX ′ of FIG. Note that, in the present embodiment, portions corresponding to the above-described conventional example are denoted by the same reference numerals, and redundant description is omitted.

As shown in FIGS. 7 to 10, in the present embodiment, two elongated oblong slits 11 are formed in each bottom wall 4 along the fold line L1. In the present embodiment, each slit 11 has a width of about 3 mm and a length of about 95 m.
m so as to occupy about 80% of the total length of the diagonal line of the bottom wall 4 (about 170 mm × 170 mm). By doing so, in a state where the three-dimensional picture book is assembled,
Since the force for bending the bottom wall 4 along the fold line L1 to form a mountain shape is less likely to act, the bottom wall 4 is closer to a flat surface than the conventional product, and it is easy to place objects such as dolls. The shape and dimensions of the slit are not limited to those described above.

As shown in FIG. 11, in this embodiment, a transparent polypropylene film 12 having a thickness of 15 μm is applied so as to cover the entire inner surfaces of the first to fourth structural members 1A, 1B, 1C and 1D. Is being worn. By doing so, it is possible to prevent the bottom wall 4 from breaking along the fold line L1. Further, by adhering the film 12, the water resistance is improved and the gloss is increased, so that the appearance is also improved. Further, by attaching the film 12, the rigidity is improved, and the thickness of the sheet (paperboard) as the base material layer can be reduced.
Manufacturing costs are reduced. For the purpose of only preventing the bottom wall 4 from breaking, the entire slit 11 and only the surrounding area may be covered with a film.
The material and thickness of the film are not limited to those described above.

Further, in the present embodiment, the angle r at which the first side wall 2 and the second side wall 3 of each bottom wall 4 intersect is formed.
(See FIGS. 9 and 10) is 89 °. Therefore, the maximum opening angle between the first side wall 2 of the first component 1A and the second side wall 3 of the fourth component 1D is 89 ° × 4 = 3.
Even if it is opened to the maximum, the loop-shaped members 8A, 8B of the velvet type fastener and the hook-shaped members 9A, 9B cannot be brought into contact with each other. It is necessary to forcibly open the first side wall 2 of 1A and the second side wall 3 of the fourth component 1D beyond this maximum opening angle.

Therefore, when the loop members 8A, 8B and the hook members 9A, 9B are engaged, the first to fourth
The first side wall 2 and the second side wall 3 of the component member are in a state of being pulled in a direction in which the angle between them becomes large,
Each bottom wall 4 is given a force in the direction of flattening, which makes it more difficult for the bottom wall 4 to bend in a mountain shape along the fold line L1. Note that the angle r for producing such an effect is not limited to 89 °, but may be less than 90 °.
It is preferably about 7 to 89.5 °.

The present invention is not limited to the above-described embodiment, and various modifications can be made to the above-described embodiment without departing from the gist of the present invention.

[0025]

As described above, according to the present invention, a slit is formed along each fold line in each bottom wall,
Because it becomes difficult for the bottom wall to bend into a mountain shape along the fold line,
It becomes easier to place objects such as dolls on the bottom wall.

According to the second aspect of the present invention, since the resin film is adhered to each bottom wall so as to cover each slit and the surrounding area, the bottom wall is less likely to break along the slit. .

According to the third aspect of the present invention, since the resin film is transparent and formed so as to cover the entire inner surfaces of the first to fourth components, the water resistance and appearance are improved. Further, since the thickness of the sheet as the base material layer can be reduced, the manufacturing cost is reduced.

According to the fourth aspect of the present invention, the angle at which the first side wall and the second side wall intersect at each bottom wall is 9 degrees.
When the angle is less than 0 °, a force in the direction of flattening acts on each bottom wall, and each bottom wall becomes flatter.
