On the other hand, a 3D model of paper craft is made from a pattern, so it needs to be movable with a simple structure.

  Therefore, an object of the present invention is to provide a paper craft that can move two parts in opposite directions with a simple structure.

In order to achieve the above object, the present invention is a paper craft in which a three-dimensional model is produced from a pattern printed on a sheet material, and the sheet material is moved as a pattern along a predetermined movable direction in an assembled state. A movable portion, a housing portion that houses the assembled movable portion, and an operation portion that is connected to the movable portion at one end and protrudes from the housing portion that is assembled at the other end are provided.
The movable portion includes a first movable surface portion, a second movable surface portion, a first connection surface portion, a second connection surface portion, a first movable piece, and a second movable piece.
The first movable surface portion is formed in a band shape, and the longitudinal direction is the movable direction. The second movable surface portion is formed in a band shape, the longitudinal direction thereof becomes the movable direction, and faces the first movable surface portion in an assembled state. The first connecting surface portion connects one end portion in the longitudinal direction of the first movable surface portion and one end portion in the longitudinal direction of the second movable surface portion. The second connecting surface portion connects the other end portion in the longitudinal direction of the first movable surface portion and the other end portion in the longitudinal direction of the second movable surface portion. The first movable piece extends from at least one side edge in the short direction of the first movable surface portion, and extends toward the second movable surface portion in an assembled state. The second movable piece extends from at least one side edge in the short direction of the second movable surface portion, and extends toward the first movable surface portion in an assembled state.
Moreover, the said accommodating part has a side part and an opening part.
The side portion covers a side of the movable portion in which the first movable piece and the second movable piece are extended in an assembled state. The opening is provided in the side surface and exposes the first movable piece and the second movable piece in an assembled state.

Therefore, in the paper craft of the present invention, when the movable portion is assembled, the longitudinal end portions of the first movable surface portion and the longitudinal end portions of the second movable surface portion are connected to each other, and the first and second movable surface portions face each other. Becomes a belt. At this time, the first movable piece and the second movable piece extending from at least one side edge in the short direction of the endless belt-like movable portion are extended in opposite directions. Then, the movable part is accommodated in the assembled accommodating part, one end of the operation part is connected to the movable part, and the other end is protruded from the accommodating part to produce a three-dimensional model.
In such a three-dimensional model, when the operation unit is operated in a predetermined direction, the movable unit is moved by the operation force. At this time, since the longitudinal direction of the belt-like first and second movable surface portions is the movable direction, the endless belt-like movable portion rotates along the movable direction (longitudinal direction) and is opposed to the opposing first movable surface portion. The second movable surface portion moves in directions opposite to each other. Thereby, the 1st movable piece extended from the 1st movable surface part and the 2nd movable piece extended from the 2nd movable surface part move to a mutually opposite direction.
As a result, the two parts (the first movable piece and the second movable piece) can be moved in opposite directions with a simple structure.

That is, the first movable surface portion 11 and the second movable surface portion 12 move in the opposite directions along the movable direction X.

  Thereby, the 1st movable piece 15 integrally formed in the 1st movable surface part 11 and the 2nd movable piece 16 integrally formed in the 2nd movable surface part 12 will move to a mutually opposite direction, A pair of adjacent first and second movable pieces 15 and 16 is taken as a set, and these are close to each other.

  Although not shown here, when the step portions 31d and 32d of the operation unit 30 interfere with the inside of the operation opening 21f and the movement of the operation unit 30 is prevented, the rotational movement of the movable unit 10 stops. .

In this state, as shown in FIG. 6A, a pair of adjacent first and second movable pieces 15 and 16 is set as a set, and there is no gap therebetween. That is, the right edge 15b (in FIG. 6A) of the first movable piece 15 and the left edge 16b (in FIG. 6A) of the second movable piece 16 are close to each other. Further, at this time, as shown in FIG. 6B, the pair of first and second movable pieces 15 and 16 are openings formed in the side surface region 21 b of the accommodating portion 20 in a state where the side edge portions 15 b and 16 b are close to each other. One set of the first and second movable pieces 15 and 16 exposed to the part 21e and in the state of being close to each other by one opening 21e is exposed.
Here, the side area 21b of the accommodating portion 20 is printed to simulate the side of a train, and the first movable piece 15 and the second movable piece 16 are both printed to simulate a train door. ing. Therefore, the train model 1 can imitate the state in which the door is closed by exposing the pair of first and second movable pieces 15 and 16 from one opening 21e (see FIG. 6B).

Next, in the train model 1 simulating a state in which the door is closed, when the operation unit 30 is pushed in the direction B to be inserted into the accommodation unit 20, the endless belt-like movable unit 10 is moved in the movement direction X in the accommodation unit 20. Along (clockwise in FIG. 7A).
At this time, the first movable surface portion 11 moves toward the left side (in FIG. 7A), and the second movable surface portion 12 moves toward the right side (in FIG. 7A). That is, the first movable surface portion 11 and the second movable surface portion 12 move in the opposite directions along the movable direction X.

  Thereby, the 1st movable piece 15 integrally formed in the 1st movable surface part 11 and the 2nd movable piece 16 integrally formed in the 2nd movable surface part 12 will move to a mutually opposite direction, A pair of adjacent first and second movable pieces 15 and 16 is taken as a set, and these are separated from each other.

  And if the longitudinal direction edge part of the screen part 18 interferes with the 2nd upper guide part 26A and the 2nd lower guide part 26B, the rotational movement of the movable part 10 will be blocked | prevented and the movement of the operation part 30 will stop.

  In this state, as shown in FIG. 7A, a gap is generated between a pair of adjacent first and second movable pieces 15, 16. Further, at this time, the pair of first and second movable pieces 15 and 16 whose side edge portions are separated from each other enter the inside of the side surface region 21b of the accommodating portion 20, and as shown in FIG. Becomes open. And the design printed on the screen part 18 standingly arranged from the 1st movable surface part 11 is exposed from the opening part 21e. Thereby, the train model 1 can simulate the state in which the door is opened (see FIG. 7B).

  Thus, in the paper craft of Example 1, when the operation unit 30 is moved in a certain direction (direction A pulled out from the storage unit 20 or direction B inserted into the storage unit 20) in the assembled state, the endless belt-like shape is obtained. The movable part 10 rotates along the movable direction X. Thereby, two parts (the 1st movable piece 15 and the 2nd movable piece 16) provided in the state which opposed in movable part 10 move in the mutually opposite direction. As a result, the two parts (the first movable piece 15 and the second movable piece 16) can be moved in opposite directions with a simple structure.

In the first embodiment, the third movable piece 17A is formed on the first movable surface portion 11, and the third movable piece 17B is formed on the second movable surface portion 12.
The third movable pieces 17A, 17B are separated from each other by pushing the operating portion 30 in the direction B in which the operation portion 30 is inserted into the accommodating portion 20 so that the adjacent first and second movable pieces 15, 16 are separated from each other. When it overlaps with 21b and the opening 21e is opened, as shown in FIG. 7B, it is exposed from the opening 21e with this operation.

That is, the third movable pieces 17A and 17B are provided at positions that are exposed from the opening 21e when the first movable piece 15 and the second movable piece 16 are not exposed from the opening 21e in the assembled state. As a result, the third movable pieces 17A and 17B face the opening 21e as soon as the first movable piece 15 and the second movable piece 16 enter the inside of the side surface region 21b, and can be seen through the opening 21e. .
Here, the third movable pieces 17A and 17B are printed to imitate the passengers of the train. Therefore, in the train model 1, when the door is opened, it is possible to simulate a state in which passengers come out from the opened door (see FIG. 7B).

In the paper craft of the first embodiment, a plurality of first movable pieces 15 are extended from the side edge portions 11 a and 11 b of the first movable surface portion 11, and the second movable piece 16 is a side edge of the second movable surface portion 12. A plurality of portions are extended from the portions 12a and 12b.
Therefore, like the train model 1, two parts (first movable piece 15 and second movable piece 16) moving in opposite directions to each other as a set, and two parts (first movable piece moving in the opposite direction in the longitudinal direction). A plurality of sets of the pieces 15 and the second movable pieces 16) can be arranged and can be moved simultaneously. Thereby, the train model 1 can be made more faithful to the real thing.

  Furthermore, in the paper craft of the first embodiment, the first movable piece 15 is extended from both side edge portions 11a and 11b in the short direction of the first movable surface portion 11, and the second movable piece 16 is the second movable piece 16. The movable surface portion 12 extends from both side edge portions 12a and 12b in the short direction. And the movable part 10 has the screen part 18 standingly arranged from the 1st movable surface part 11 in an assembly state.

Therefore, when the pair of first and second movable pieces 15 and 16 move in directions opposite to each other, enter the inside of the side surface region 21b of the housing portion 20 and the opening portion 21e is opened, the first portion is opened. Thus, it is possible to prevent the back sides of the second movable pieces 15 and 16 from being seen. Thereby, the appearance of the train model 1 can be improved.
Moreover, in the first embodiment, the state of the train (seats, windows, etc.) is printed on the entire surface of the partition 18. Therefore, not only when viewed from the front of the opening 21e but also when looking into the inner space 24 of the housing main body 21 from a direction oblique to the opening 21e, there is no sense of incongruity.

Moreover, in the paper craft of Example 1, the ceiling area | region 21a of the accommodating part main body 21 is a rectangular area | region which has the length of a longitudinal direction slightly shorter than the length of the movable direction X of the movable part 10 of an assembly state. Therefore, the length of the accommodating part 20 in the movable direction X is slightly shorter than the length of the movable part 10 in the assembled state in the movable direction X.
Thereby, when the movable part 10 is accommodated in the accommodating part 20, it is crushed slightly along the movable direction X (longitudinal direction). Therefore, when the pair of first and second movable pieces 15, 16 are exposed from the opening 21e, the right edge 15b (in FIG. 6) of the first movable piece 15 and the second movable piece 16 (FIG. 6). The left edge 16b can be brought close to the left edge 16b. As a result, the appearance of the train model 1 can be improved when the train model 1 simulates a state where the door is closed.

In the paper craft of the first embodiment, the first upper guide portion 25A and the first lower guide portion 20 are in contact with the first connecting surface portion 13 on the inner space 24 side of the portion where the accommodating portion 20 is the both end portions in the movable direction X in the assembled state. A guide portion 25B, a second upper guide portion 26A, and a second lower guide portion 26B that are in contact with the second connecting surface portion 14 are provided.
Therefore, as shown in FIGS. 6A and 7A, when the movable unit 10 is rotated in the direction A in which the operation unit 30 is pulled out from the storage unit 20 or in the direction B in which the operation unit 30 is inserted into the storage unit 20, Since the second connecting surface portions 13 and 14 extend along the guide portions 25A to 26B, excessive deformation of the first and second connecting surface portions 13 and 14 is suppressed. Thereby, the rotational movement of the movable part 10 can be made smooth, and the deformation and breakage of the movable part 10 can be prevented to make a highly durable paper craft.
Further, as shown in FIG. 7A, when the operation unit 30 is pushed in the direction B in which the operation unit 30 is inserted into the housing unit 20, the first movable surface unit 11 and the second movable unit are moved to the first upper guide unit 25A and the second lower guide unit 26B. The movement of the operation unit 30 is stopped by the interference of the surface unit 12. That is, the movement amount (operation amount) of the operation unit 30 can be easily adjusted by adjusting the size and shape of each guide unit 25A to 26B.
