[0022] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The present invention is not limited to the following embodiments, but also includes changes and deformations of the structure within the scope of the gist of the present invention. In addition, the combination of the features described in all embodiments is not necessarily necessary for the invention. In addition, the same reference numerals are used for the same structural elements, and their descriptions are omitted.

[0023] A configuration example of a model toy 10 according to an embodiment of the present invention will be described. Figure 1 1 is a diagram showing an example of the external appearance structure of the model toy 10 of the present embodiment. In addition, the arrows X, Y, and Z respectively indicate the directions of the front direction, the left direction, and the upward direction of the model toy 10, and the same applies to the other drawings.

[0024] The model toy 10 includes a head 11, a chest 12, arms 13a-13b, legs 14a-14b, and a waist 15 constituting a main body. In the present embodiment, a humanoid robot is used as an example of the model toy 10, but the present invention is not limited thereto, and the present invention can be applied to various models such as humans, animals, robots, insects, dinosaurs, weapons, and decorative parts.

[0025] The head 11 is connected to the chest 12. The right arm 13a and the left arm 13b are connected to the chest 12 at the sides, and the waist 15 is connected to the lower part. The waist 15 includes a hip joint and is connected to the right leg 14a and the left leg 14b. In addition, a right hand member 16a and a left hand member 16b are attached to the front ends of the right arm 13a and the left arm 13b, respectively.

[0026] In addition, in the arm parts 13a-13b and the leg parts 14a-14b of the model toy 10 of the present embodiment, a movable structure 20 having a bellows-shaped appearance is applied as a joint part (elbow joint part, knee joint). In such a structure, it is required to realize the movement of the joints of a person, an animal, etc., for the movable structure 20 corresponding to the joint part. For example, in the model toy 10 of the present embodiment configured as a humanoid robot, it is required to realize the movement of the joints of a person, etc., for the movable structure 20.

[0027] <Structure of movable structure>

[0028] Hereinafter, a configuration example of the movable structure 20 in the right arm portion 13 a of the model toy 10 according to the present embodiment will be described. Figure 2 1 is a diagram showing a configuration example of the movable structure 20 of the right arm 13a. The movable structure 20 of the right arm 13a includes a shaft 21 and an outer decoration 22 surrounding the shaft 21. Figure 2 In the figure, the front half of the exterior portion 22 is omitted in order to show the structure of the shaft portion 21. Figure 2 , shows the cross-sectional structure of the exterior portion 22. In addition, the following representatively describes the structure of the movable structure 20 of the right arm 13a, but the movable structure 20 having the same structure as the right arm 13a can also be applied to the left arm 13b and the legs 14a to 14b.

[0029] The shaft portion 21 is formed by arranging a plurality of inner components (first component) 21a to 21c. Specifically, the inner components 21a to 21c are connected to each other in a rotatable manner. The inner component 21b is connected to the inner component 21a in a rotatable manner around the rotation axis A1, and the inner component 21c is connected to the inner component 21b in a rotatable manner around the rotation axis A2. Figure 2 In the movable structure 20 shown, the shaft portion 21 is composed of three inner members 21a to 21c, but the number of inner members included in the shaft portion 21 is not limited to three, and may be two or four or more.

[0030] The exterior part 22 is formed by arranging a plurality of outer parts (second parts) 22a to 22e along the axial direction of the shaft part 21. Each outer part 22a to 22e is formed in an annular shape surrounding the shaft part 21, that is, it is formed in an annular shape including an opening for the shaft part 21 to pass through. Each outer part 22a to 22e is not fixed (connected) to the shaft part 21, but is configured to be movable (for example, rotatable) relative to the shaft part 21. In addition, the plurality of outer parts 22a to 22e are not fixed (connected) relative to each other, but are configured to be movable (for example, rotatable) in the shaft part 21 independently of each other. By arranging such a plurality of outer parts 22a to 22e along the axial direction of the shaft part 21, the movable structure 20 (exterior part 22) has a bellows-like appearance.

[0031] Here, the movable structure 20 of the present embodiment has a structure in which the number of outer parts 22a to 22e included in the exterior part 22 is greater than the number of inner parts 21a to 21c included in the shaft part 21. According to this structure, in the movable structure 20 used as a joint part, movements closer to the joints of humans, animals, etc. can be achieved. For example, in the movable structure 20 used as the joint part of a humanoid robot, movements closer to the joints of humans can be achieved. Figure 2 In the movable structure 20 shown, the outer part 22 includes five outer parts 22a to 22e, which is greater than the number of inner parts included in the shaft part 21. However, the number of outer parts included in the outer part 22 is not limited to five, as long as it is greater than the number of inner parts included in the shaft part 21.

[0032] In addition, the movable structure 20 may also include an anti-detachment component 23, a mounted component 24, and a cover component 25. The anti-detachment component 23 is a component mounted on the end of the shaft portion 21 (inner component 21c) to prevent the exterior portion 22 (a plurality of outer components 22a to 22e) from detaching (falling off) from the shaft portion 21. The mounted component 24 is a component mounted on the chest 12 of the model toy 10, and is rotatably connected to the anti-detachment component 23 around the rotation axis A3. The mounted component 24 may correspond to the shoulder joint of the model toy 10. In addition, the cover component 25 is a component that is part of the appearance of the movable structure 20 and covers the anti-detachment component 23. Figure 2 The cross-sectional structure is shown in FIG.

[0033] Next, refer to Figure 3 to Figure 6 The assembly of the movable structure 20 will be described in order, thereby showing a configuration example of the movable structure 20 . Figure 3 to Figure 6 This is a diagram for explaining the assembly of the movable structure 20 .

[0034] Figure 31 is a diagram showing the assembly of the shaft portion 21. As described above, the shaft portion 21 of the movable structure 20 of the present embodiment includes three inner members 21a to 21c.

[0035] First, if Figure 3 As shown in (a), the inner members 21a and 21b are connected to each other so as to be rotatable. Specifically, a protrusion C is provided at one end of the inner member 21a. 11 An opening C is provided at one end of the inner member 21b. 12 The inner members 21a and 21b are formed by making the protrusions C 11 With opening C 12 Thus, the inner member 21a and the inner member 21b are connected by the protrusion C 11 The extension axis is set as the rotation axis A1 and is connected in a rotatable manner. Figure 3 In the example of FIG. 1 , a protrusion C is provided on the inner member 21a. 11 The inner part 21b is provided with an opening C 12 However, an opening may be provided in the inner part 21a, and a protrusion may be provided in the inner part 21b.

[0036] Then, if Figure 3 As shown in (b), the inner members 21b to 21c are connected to each other so as to be rotatable. Specifically, an opening C is provided at the other end of the inner member 21b. 21 A protrusion C is provided at one end of the inner member 21c. 22 The inner members 21b to 21c are formed by openings C 21 With protrusion C 22 Thus, the inner member 21b and the inner member 21c are connected by the protrusion C 22 The extension axis is set as the rotation axis A2 so as to be connected in a rotatable manner. Figure 3 In the example, the inner member 21b is provided with an opening C 21 The inner part 21c is provided with a protrusion C 22 However, a protrusion may be provided on the inner part 21b, and an opening may be provided on the inner part 21c.

[0037] Figure 4-5 1 is a diagram showing the assembly of the exterior portion 22. As described above, the exterior portion 22 of the movable structure 20 of the present embodiment includes five outer members 22a to 22e.

[0038] First, if Figure 4As shown in (a), the outer member 22a is mounted on the shaft 21 to which the plurality of inner members 21a to 21c are connected. Specifically, the end of the inner member 21c is inserted into the opening of the outer member 22a which is formed into a ring shape, and the outer member 22a is moved along the axial direction of the shaft 21 to the root of the shaft 21 (i.e., the position of the inner member 21a). Thus, the outer member 22a is mounted on the shaft 21.

[0039] Then, if Figure 4 As shown in (b), the outer member 22b is installed on the shaft portion 21. Specifically, the end of the inner member 21c is inserted into the opening of the outer member 22b formed in an annular shape, and the outer member 22b is moved along the axial direction of the shaft portion 21 to the position of the outer member 22a installed on the shaft portion 21. In this way, the outer member 22b is installed on the shaft portion 21.

[0040] Likewise, Figure 4 (c)~ Figure 4 As shown in (d) of FIG. 1 , the outer parts 22c to 22d are installed on the shaft part 21. Specifically, as Figure 4 As shown in (c), the end of the inner member 21c is inserted into the opening of the outer member 22c formed into an annular shape, and the outer member 22c is moved along the axial direction of the shaft 21 to the position of the outer member 22b already installed on the shaft 21. Figure 4 As shown in (d), the end of the inner member 21c is inserted into the opening of the outer member 22d formed in an annular shape, and the outer member 22d is moved along the axial direction of the shaft portion 21 to the position of the outer member 22c already mounted on the shaft portion 21. Thus, the outer members 22c to 22d are mounted on the shaft portion 21.

[0041] Finally, if Figure 5 As shown in (a), the outer member 22e is installed on the shaft portion 21. Specifically, the end of the inner member 21c is inserted into the opening of the outer member 22e which is formed into a ring shape, and the outer member 22e is moved along the axial direction of the shaft portion 21 to the position of the outer member 22d installed on the shaft portion 21. In this way, the outer member 22e is installed on the shaft portion 21, as shown in FIG. Figure 5 As shown in FIG. 2 ( b ), a plurality of outer members 22 a to 22 e of the exterior portion 22 are arranged around the shaft portion 21 .

[0042] Here, if Figure 4 (a)~ Figure 4 As shown in (d), the outer parts 22a to 22d included in the exterior part 22 can each include, for example, a first annular portion P1 and a second annular portion P2 continuous with the first annular portion P1. The first annular portion P1 has an opening slightly larger than the outer shape (outer periphery) of the shaft portion 21. The second annular portion P2 has an opening larger than the outer shape (outer periphery) of the first annular portion P1. In addition, Figure 5 The outer member 22e shown in (a) includes only the second annular portion P2 and does not include the first annular portion P1.

[0043] In such a structure, a plurality of outer components 22a to 22e are arranged in such a manner that a portion of the first annular portion P1 of one of the outer components adjacent to each other is covered by a portion of the second annular portion P2 of another one. Specifically, a portion of the first annular portion P1 of the outer component 22a is covered by a portion of the second annular portion P2 of the outer component 22b. Similarly, a portion of the first annular portion P1 of the outer component 22b is covered by a portion of the second annular portion P2 of the outer component 22c, a portion of the first annular portion P1 of the outer component 22c is covered by a portion of the second annular portion P2 of the outer component 22d, and a portion of the first annular portion P1 of the outer component 22d is covered by the outer component 22e. Thus, as Figure 5 As shown in (b) , the exterior portion 22 can be provided with a bellows-like appearance, and the exterior portion 22 can be flexibly deformed according to the bending (rotation) of the shaft portion 21 at each of the rotation axes A1 to A2 .

[0044] Figure 6 2 is a diagram showing the assembly of the anti-separation component 23, the mounted component 24, and the cover component 25. Figure 6 As shown in (a), the anti-separation component 23 includes two members 23a-23b that sandwich the end of the shaft portion 21 (inner member 21c), and the anti-separation component 23 is mounted on the end of the shaft portion 21 by sandwiching the end of the shaft portion 21 with the two members 23a-23b. The mounted component 24 is rotatably connected to the anti-separation component 23 by sandwiching the two members 23a-23b of the anti-separation component 23. In addition, as shown in FIG. Figure 6 As shown in (b), the cover member 25 is mounted on the anti-detachment member 23 in a manner covering the anti-detachment member 23. Figure 6 As shown in (c) of FIG. 1 , a movable structure 20 having a bellows-like appearance is constructed.

[0045] As described above, the movable structure 20 of the present embodiment has a structure in which the number of the outer parts 22a to 22e included in the exterior part 22 is greater than the number of the inner parts 21a to 21c included in the shaft part 21. In other words, the movable structure 20 of the present embodiment has a structure in which the number of movable parts formed between the adjacent outer parts at the exterior part 22 is greater than the number of movable parts formed between the adjacent inner parts at the shaft part 21. With this structure, in the movable structure 20 used as a joint part, it is possible to realize a movement closer to the joints of humans, animals, etc.
