  By the way, it is difficult to make a three-dimensionally shaped object having a complicated shape from a sheet of one pattern. Therefore, for example, when configuring a finger puppet, it is easier to make the head and the torso from separate patterns of sheet bodies and connect them together. However, if the connection method is not appropriate, there is a disadvantage that the connection is not secure and it is easy to leave, and the work associated with the connection is troublesome.

  In view of the above problems, the present invention provides a three-dimensional structure that can quickly and securely connect a plurality of three-dimensional structures made from sheet bodies of different patterns to a practically satisfactory level. Objective.

In order to solve the above problems, the present invention adopts the following configuration.
That is, a sheet-like object is bent to form a plurality of three-dimensional objects, and each of the plurality of three-dimensional objects is connected by connecting means, and the connecting means is on one side. A polygonal hole is formed, and the other is formed with a polygonal pyramid corresponding to the shape of the hole, and an engaging piece is formed on the polygonal pyramid to engage the inside of the corner of the hole. Construct a shaped body.

  The three-dimensional modeled body of the present invention is easy to manufacture, can quickly connect a plurality of three-dimensional modeled objects, and the connection of a plurality of three-dimensional modeled objects becomes difficult to release due to the action of the engagement pieces. .

Hereinafter, an embodiment of the present invention will be described with a finger puppet as an example with reference to the drawings.
Fig.1 (a) is a top view which shows the pattern for comprising the head of a finger puppet, and FIG.1 (b) is a top view which shows the pattern for comprising the trunk | drum of a finger puppet. The material can be paper, cardboard, plastic film or other sheet-like material.

  In FIG. 1A, a base piece 1 is provided at the center of a head piece 68, and a trapezoidal piece 2 that is a part of a lower lid is connected to the lower side of the base piece 1. Further, the lower side of the trapezoidal piece 2 communicates with one side of the pentagonal bottom piece 3, and trapezoidal pieces 4, 5, 6 similar to the trapezoidal piece 2 from the remaining sides of the bottom piece 3. 7 are extended. Tongue pieces 8, 9, 10, and 11 are formed at the tips of these trapezoidal pieces 4, 5, 6, and 7, respectively. A pentagonal hole 12 is formed at the center of the bottom piece 3.

  On the other hand, a similar configuration is formed on the upper side of the base piece 1, that is, trapezoidal pieces 13, 14, 15, 16, 17 tongue pieces 18, 19, 20, 21 and a top piece 22 are formed. There are no holes in the top piece.

  The left and right sides of the base piece 1 communicate with side pieces 23, 24, 25, and 26, and these side pieces 23, 24, 25, and 26 are connected to the side pieces 27, 28, 29, 30, 31, 32, 33, 34 and cut lines 35, 36, 37, 38, 39, 40, 41, 42 are formed. A tongue piece 43 is formed on the left side of the side piece 25, and a marginal piece 44 and a cut 45 are formed on the right side of the side piece 26.

  In FIG. 1B, the substantially sector-shaped body piece 46 is divided into five division pieces 47, 48, 49, 50, 51 by division lines 52, 53, 54, 55. , 53, 54, 55 are provided with steps slightly so that engagement pieces 56, 57, 58, 59, 60 described later are formed, and cutting lines (starting from the step portion and penetrating through the upper end) 61, 62, 63 , 64 are provided. Further, tongue pieces 65a and 65b are formed on the right side of the segment piece 51, and cuts 66a and 66b for receiving the tongue pieces 65a and 65b are formed on the left side of the segment piece 47. And a tongue piece 67 is formed.

  Thus, in order to form a three-dimensional modeled object that is a torso of a finger puppet, first, the torso piece 46 is bent according to the dividing lines 52, 53, 54, and 55. Next, the outer surface of the tongue piece 67 is brought into contact with the inner surface of the segment piece 51, and then the tongue pieces 65a and 65b are inserted into the notches 66a and 66b. By doing so, the body of the five-sided pyramid finger doll is completed.

  Next, in order to form a three-dimensional modeled object that is the head of a finger doll, each piece excluding the base piece, the side piece, and the piece 44 of the head piece 68 is bent at an adjacent boundary portion. Next, the outer surface of the marginal piece 44 is brought into contact with the inner surface of the side piece 25, and then the tongue piece 43 is inserted into the cut 45. Next, each of the trapezoidal pieces is bent at a boundary portion between the base piece 1 and the bottom piece 3 or the top piece 22 adjacent to each other. The tongue piece 8 at the cut 38, the tongue piece 9 at the cut 42, the tongue piece 10 at the cut 40, the tongue piece 11 at the cut 36, and the tongue piece 18 at the cut 35. The tongue piece 19 is inserted into the cut 39, the tongue piece 20 is inserted into the cut 41, and the tongue piece 21 is inserted into the cut 37 from the outer surface side of each piece. In this way, a finger puppet with a pentagonal pyramid having a top piece on a pentagonal cylinder and a pentagonal pyramid having a bottom piece on the bottom is completed.

In order to form a three-dimensional modeled body that is a finger puppet, the tip of the pentagonal pyramid finger doll faces the hole 12 in the finger doll head and is pushed in as it is. Then, the stepped portions such as the cutting lines 61, 62, 63, 64 play the role of the engaging pieces 56, 57, 58, 59, 60,
These engage with the inside of the bottom piece 3 so that the body portion is difficult to be detached from the head portion and sufficiently serves as a connecting means. The work time associated with the connection can be as short as necessary. The completed finger puppets are used as a doll by painting a cotton-like disentangled paper and drawing a decorative pattern on it. The finger is inserted into the body of the pentagonal pyramid. In the above-described embodiment, the shape of the body portion formed from the hole 12 or the body portion piece 46 is a pentagon (pentagon, pentagon), but may be a quadrilateral, a hexagon, a heptagon, an octagon, or other polygons. . Moreover, not only when connecting two three-dimensional model | molding objects and comprising in one three-dimensional model | molding body, but also when connecting three or more three-dimensional model | molding objects and comprising in one three-dimensional model | molding body. The present invention can be applied.

(A) is a top view which shows the pattern for comprising the head of a finger puppet. (B) is a top view which shows the pattern for comprising the trunk | drum of a finger puppet.
