Description

The present invention relates to a joint structure of a doll body.

Doll toys are known that are constructed by assembling different parts and can be played with in various poses. For example, Patent Document 1 discloses a joint mechanism for a doll toy in which connecting parts such as shoulders are formed of a soft material and the movable range is expanded by deforming or bending.

Registered utility model publication No. 3185443

Now, one of the design themes for doll toys is the design of humanoid robots. In doll toys designed as humanoid robots, the main trunk parts such as the chest, abdomen, and waist are often linear and mechanically designed and covered with armor. Conventionally, these trunk parts are one box-shaped part. It has been designed as. As a result, it was easy for the movable parts of the trunk to be difficult to move.

Specifically, for example, in TV anime and manga about heroes, the pose of holding a sword or gun with both arms stretched out in front of the chest and holding a gun is often seen, so as a user, I would definitely like to recreate that with a doll toy. I hope so. However, if the chest is designed as one box-shaped body as in the past, the position of the shoulder portion of the upper arm connected to the shoulder joint is almost fixed. Therefore, even if you tried to make a pose where the arms were extended forward, only the arms would bend forward while the shoulders remained in the same position, resulting in a so-called ``forward forward'' pose. Also, in some cases it was possible to fold both hands by pointing the arms forward and bending the elbow joints, but this resulted in an ungainly "stance" that was far removed from the original "stance" of extending the arms. Ta. In any case, his wish was not fulfilled.

It is conceivable that the above-mentioned "stance" may be realized by using the joint mechanism using a soft material disclosed in Patent Document 1. However, if the wrinkles and flexures of the soft material become visible, the original attractiveness of the exterior design will be lost, although the ``posture'' itself will be possible. Furthermore, since the bent soft material tries to recover, the above-mentioned "stance" cannot be maintained.

The above-mentioned "stance" problem is just one example, and problems also occur in other joints when the joints are bent significantly (or deeply).
An object of the present invention is to provide a technique that can increase the degree of freedom of movement of joints while suppressing the reduction in attractiveness of the external design.

The joint structure of the doll body according to the present invention is a joint structure of the doll body, which includes a first part (for example, the chest 20 in FIG. 8 and the abdomen 30 in FIG. 14) that constitutes the trunk, the first part that constitutes the limbs, and the first part that constitutes the trunk. a second part that is rotatable with respect to the first part (for example, the upper arm 40 in FIG. 8 and the thigh 44 in FIG. 14); a third part that is rotatable relative to the second part, and when the third part is rotated to reduce the angle formed between the second part and the first part, the third part is rotatable in accordance with the rotation of the second part; A third part configured to be rotatable in a direction to reduce the angle (for example, the left chest part 24 and the right chest part 26 of the chest 20 in FIG. 8, the large hanging part 81 in FIGS. 83 and a right apron portion 84).

Further, in the present invention, the first part and the third part are arranged so that, when the third part is rotated in a direction that reduces the angle formed, one part overlaps with the outside and the other part overlaps with the inside. It may also be a configuration.

Further, in the present invention, the third part may have a tapered surface at an end closer to the first part to avoid contact with the first part during rotation.

Further, in the present invention, when viewed from above, a movable shaft for changing the angle of the second part (for example, the left arm ball stud 243 and the left shoulder shaft 244 in FIG. 3) is a movable shaft for changing the orientation of the third part. It may be configured to be provided at a position farther from the center of the trunk than the movable axis (for example, the left swing axis 226 in FIG. 3).

Further, in the present invention, the first part may be a part for the center of the chest, the second part may be a part for the arms, and the third part may be a part located on the left and right sides of the chest.

Further, in the present invention, the third part may include a support part that supports the second part.

Further, in the present invention, when viewed from the front, a movable shaft for rotating the second part (for example, the ball stud 75 in FIGS. 14 and 15) is a movable shaft for rotating the third part (for example, the ball stud 75 in FIGS. 14 and 15). For example, it may be configured to be provided below the Odare movable shaft 74) in FIG. 15.

Further, in the present invention, the third part has a portion above and a portion below a movable shaft for rotating the third part (for example, the Odare movable shaft 74 in FIG. 15), and When the third part is rotated in a direction that reduces the angle formed by the third part, one of the upper part and the lower part of the third part moves to the outside of the first part, and the other part moves to the outside of the first part. It may be configured to partially overlap the inside of the part (eg, FIGS. 16 to 19).

Further, in the present invention, the first part is an abdominal part (for example, the abdomen 30 in FIG. 14), and the second part is a leg part (for example, the thigh part 44 in FIG. 14). , the third part may be a part for the appearance of the waist (for example, the large droop part 81 in FIG. 14).

Further, in the present invention, the third part is configured to swing with respect to the first part, one end supports the swing shaft of the third part, and the other end is a link supported pivotally. The apparatus further includes a part (for example, the Odari link 72 in FIG. 15), and by vertically swinging the link part about the other end, the position of the swing axis of the third part can be adjusted up and down. may be configured.

Further, the present invention provides a space for preventing interference between the first part and the third part by swinging the link part downward when the second part is rotated so as to reduce the formed angle. It may be configured such that it is possible to expand the .

[First embodiment]
FIG. 1 is a perspective external view of the upper body portion of the toy doll in the first embodiment.
The doll toy 2 is a toy constructed by assembling different parts. In the illustrated example, the head 10, thorax 20, abdomen 30, upper arm 40, and back bag 50 of the doll toy 2 are selectively illustrated. Parts (for example, lower arms, waist, legs, etc.) are also provided as appropriate. The user can enjoy various poses of the doll toy 2 by arbitrarily changing the relative orientation and posture of each of these parts.

The chest 20 of this embodiment includes a central chest part 22, a left chest part 24, and a right chest part 26.
Physically, the central chest part 22 is the first part constituting the trunk, and forms the left and right center portions of the chest 20 in this embodiment. The left chest part 24 and the right chest part 26 are part of the trunk or third parts that constitute the appearance of the trunk. In this embodiment, a right half body corresponds to the right shoulder and right lung region, and a left half body corresponds to the left shoulder and left lung region, respectively. The outer surface of the central chest part 22, the outer surface of the left chest part 24, and the outer surface of the right chest part 26 form an integrally continuous appearance of the chest 20.

FIG. 2 is a front view of the doll toy 2 in this embodiment, including a partial cross-sectional view of the front side of the left chest part 24.
FIG. 3 is an exploded front view of the doll toy 2 in this embodiment, including a partial cross-sectional view of the front side of the left chest part 24.
FIG. 4 is a top view of the doll toy 2 of this embodiment.

As shown in FIG. 3, the central chest part 22 of this embodiment is bilaterally symmetrical and includes an upper part 221 and a lower part 222.
The upper part 221 is a substantially box-shaped body with openings on the left, right, and lower sides, and forms the upper surface, central front surface, and central rear surface of the chest 20. The upper part has a joint part 223 for connecting the ball joint 12 to which the head 10 is connected.
The lower part 222 includes a bottom surface 224 of the chest 20 that is connected to the abdomen 30, a joint connecting column part 225 that is connected to the joint part 223, and a left swing shaft 226 that connects the left chest part 24 so as to be rotatable left and right. It has a right swing shaft 227 that pivotally supports the right chest part 26 so as to be rotatable left and right.

In this embodiment, the left chest part 24 and the right chest part 26 are bilaterally symmetrical. Hereinafter, the left chest part 24 will be explained as a representative.
The left chest part 24 is a box-shaped body that opens to the right and downward, and includes a left exterior part 241 that forms the front, side, back, and part of the upper surface of the left half of the chest, and a left swing shaft 226. It has a left bearing 242 that is inserted vertically into the left arm, and a left arm ball stud 243 that connects the left upper arm 40 (second part) with a ball joint. The left arm ball stud 243 forms the front-rear central upper surface of the left half of the chest, and is pivotably supported by a left shoulder shaft 244 provided inside the left exterior portion 241 so as to extend in the front-rear direction. That is, the doll toy 2 can be made to take a pose in which the left shoulder is raised by vertically swinging the left arm ball stud 243 using the left shoulder shaft 244.

In this embodiment, the movable shaft (left arm ball stud 243, left shoulder shaft 244) for changing the angle of the upper arm part 40 (second part) changes the direction of the left chest part 24 (third part). It is provided at a position farther from the center line L1 of the trunk than the movable axis (left swing axis 226) for moving the body (see FIG. 3). Furthermore, when viewed from above, the left swing shaft 226 is erected at a position close to the back surface of the chest with respect to the front-back center line L2 of the chest 20 (see FIG. 4).

As shown in FIG. 3, in the upper body of the doll toy 2 of this embodiment, the left swing shaft 226 is inserted into the left bearing 242, and the left chest part 24 is assembled to the lower part 222 from above. It is being In the same manner, the right swing shaft 227 is inserted into the right bearing, and the right chest part 26 is assembled to the lower part 222 from above. Furthermore, an upper part 221 is assembled from above the left chest part 24 and the right chest part 26. The upper arm part 40 is attached to the left chest part 24 and the right chest part 26, respectively, and the head 10 is attached to the joint part 223.
Therefore, as shown in FIG. 4, the right end of the left chest part 24 is inserted into the left opening of the central chest part 22, and the left end of the right chest part 26 is inserted into the left opening of the central chest part 22. is inserted into the center chest part 22 from the right opening.

FIG. 5 is a sectional view taken along the line AA in FIG. 2, with both shoulders turned rearward. As shown in FIG. 5, the doll toy 2 in this embodiment can be made to take a pose in which both shoulders are arched back and the chest is puffed out.
That is, the direction of the left chest part 24 is changed around the left swing axis 226 so that the angle formed between the rear surface of the central chest part 22 and the rear surface of the left chest part 24 that constitute the trunk is reduced. I can do it. As a result, the left arm ball stud 243 rotates backward, and the front of the chest 20 is deformed into a substantially curved shape convex toward the front, creating a pose as if the patient is puffing out his chest.

At this time, as the front end of the left chest part 24 and the end near the center chest part 22 changes direction, the part that was inserted inside the center chest part 22 is pulled out, and the left chest part 24 and the center This makes it difficult to create a gap with the chest part 22. As a result, the continuous appearance of the chest 20 is maintained appropriately. The same can be said between the right chest part 26 and the center chest part 22.

Further, tapered surfaces T are provided at the end of the left chest part 24 closer to the center chest part 22 and at the end of the right chest part 26 closer to the center of the chest. When changing the direction, contact with the central chest part 22 is avoided, and a smooth connection between the outer surfaces is created. Note that the shape of the tapered surface T is not limited to a linear sloped surface, but may be formed as a curved surface consisting of a rotating body centered on the swing axes 226 and 227 to avoid contact with the central chest part 22. It may also be formed by a free-form surface whose volume is reduced so as to.

FIG. 6 is a sectional view taken along the line AA in FIG. 2, with both shoulders turned forward. The doll toy 2 in this embodiment can be made to take a pose in which both shoulders are shrugged forward, as shown in FIG.
That is, the direction of the left chest part 24 is changed around the left swing axis 226 so that the angle formed between the front surface of the central chest part 22 and the front surface of the left chest part 24 that constitute the trunk is reduced. I can do it. As a result, the left arm ball stud 243 rotates forward and deforms so that the front width of the chest 20 in the left and right direction becomes narrower, creating a pose as if the shoulders are slumped forward. At this time, the end of the left chest part 24 closer to the front central chest part 22 is inserted further inside the central chest part 22 as the direction is changed. As a result, when trying to take a pose in which the shoulders are shrunken forward, the volume of the front chest area formed by the left chest part 24 and the center chest part 22 becomes smaller, so that the movement of the upper arm part 40 is not hindered. By doing so, while expanding the movable range of the upper arm portion 40, the continuous appearance of the chest 20 can be suitably maintained. The same can be said between the right chest part 26 and the center chest part 22.

By being able to take a pose in which both shoulders are shrugged forward, the toy doll 2 in this embodiment can be made to take more diverse and natural poses.
Specifically, as shown in FIG. 7, for example, the chest 20 is formed into one substantially box shape like a conventional doll toy (center chest part 22, left chest part 24, right chest part). If you do not have a split configuration such as 26), you will not be able to fold your shoulders forward, so even if you point your arms forward (lower side in Figure 7), you will not be able to do what is called ``Face forward''. All I can do is posture.

However, as shown in FIG. 8, if the chest 20 is divided into a central chest part 22, a left chest part 24, and a right chest part 26 as in this embodiment, both shoulders can be shrugged forward. With both arms facing forward, you can pose as if you were crossing your arms in front of your chest. For example, you will be able to recreate cool poses such as holding a gun in front of you.

Moreover, the movable axes of the left chest part 24 and the right chest part 26 (left swing axis 226, right swing shaft 227) are connected to the ball stud 243, which is the movable axis of the left and right arms, and the center of the trunk (center line L1). ) (see FIG. 3), it is possible to realize a top view that gives the impression that the central chest part 22, left chest part 24, and right chest part 26 are connected as a chest.

Furthermore, the left swing shaft 226 and the right swing shaft 227 are located close to the back surface of the chest 20 with respect to the longitudinal center line L2 (see FIG. 4). By increasing the radius of rotation of the ends of the left chest part 24 and right chest part 26 closer to the central chest part 22, the tapered surface for avoiding interference with the central chest part 22 is made smaller. This contributes to realizing the impression that the central chest part 22, the left chest part 24, and the right chest part 26 are connected as a chest when viewed from above.

[Second embodiment]
Next, a second embodiment to which the present invention is applied will be described. Hereinafter, differences from the first embodiment will be mainly described, and the same components as in the first embodiment will be given the same reference numerals and redundant explanations will be omitted as appropriate.

FIG. 9 is a front view of the upper body showing a configuration example of the doll toy 2B in this embodiment.
FIG. 10 is a partially sectional front view showing an example of the internal structure of the doll toy 2B.
FIG. 11 is a left side view of the doll toy 2B.

The chest 20 of the doll toy 2B is divided into a central chest part 22B, a left chest part 24B, and a right chest part 26B. The central chest part 22B is a substantially box-shaped body that opens left and right, and an upper part 221B and a lower part 222B are connected to each other. The left chest part 24B and the right chest part 26B are substantially bowl-shaped or substantially dish-shaped structures that respectively cover the left and right openings of the central chest part 22B. That is, the right end of the left chest part 24B covers the outside of the left opening of the central chest part 22B, the left end of the right chest part 26B covers the outside of the right opening of the central chest part 22B, and the chest 20 It forms an integrated and continuous appearance.

In this embodiment, the connection between the central chest part 22B, the left chest part 24B, and the right chest part 26B is realized by a ball joint 27. Further, in this embodiment, the connection between the upper arm portion 40 and the left chest part 24B and the right chest part 26B is realized by the ball joint 28. In other words, the degree of freedom of the shoulders and arms of the doll toy 2B of this embodiment is higher than that of the first embodiment.

Naturally, the doll toy 2B in this embodiment can also be made to take a pose in which both shoulders are shrugged forward as in the first embodiment, and the same effects as in the first embodiment can be obtained.
That is, assuming that the chest 20B is formed into one substantially box shape (assuming that it is an integral structure that is not divided into a central chest part 22B, a left chest part 24B, and a right chest part 26B). ), as shown in Fig. 12, since both shoulders cannot be shrugged forward, even if both arms are directed forward (lower side in Fig. 12), only the so-called ``line up'' posture can be achieved.

However, as shown in FIG. 13, the chest 20B is divided into a central chest part 22B, a left chest part 24B, and a right chest part 26B, so both shoulders can be shrugged forward and both arms can be stretched forward. When you turn it, you can do a crossed pose with your arms stretched out in front of your chest. For example, you will be able to recreate cool poses such as holding a sword in front of your chest.

In addition, in this embodiment, the connection between the central chest part 22B, the left chest part 24B, and the right chest part 26B is realized by the ball joint 27, so that the shoulders can be moved not only in the front but also diagonally downward and forward. , it can also be narrowed diagonally upward in front, overhead, diagonally upward in the rear, and diagonally downward in the rear. The outer surface of the central chest part 22, the outer surface of the left chest part 24, and the outer surface of the right chest part 26 form an integrally continuous appearance of the chest 20.

[Third embodiment]
Next, a third embodiment to which the present invention is applied will be described. In addition, hereafter, we will mainly discuss the differences from the first and second embodiments, and the same reference numerals will be given to the same components as in the first and second embodiments, and redundant explanations will be omitted as appropriate. do.

FIG. 14 is a front view showing a configuration example of the doll toy 2C in this embodiment.
The doll toy 2C includes a head 10, a chest 20, an abdomen 30, and a waist 60 in order from the top, and adjacent parts of these parts are connected to each other by a ball joint so that the relative angle can be changed.

The waist part 60 includes a waist base 70 and a plurality of exterior parts 80 that cover the side surfaces of the waist base 70.

The exterior part 80 includes a large flap part 81 that integrally covers the front of the waist part 60 from the navel to the groin, and a left flap part 81 that is connected to the upper end of the large flap part 81 with a ball joint and covers the front of the left and right thigh joints. 83 and a right droop part 84, a left droop part 85 and a right droop part 86 that cover the left and right side surfaces of the waist part 60, and a buttock part 87 (see FIG. 17) that covers the rear of the waist part 60. The left side hanging part 85 and the right side hanging part 86 are each supported at their upper end so as to be swingable with respect to the waist base 70 on a horizontal axis in the front-rear direction, and are connected at their lower ends so as to be swingable up and down.

FIG. 15 is an exploded perspective view showing an example of a connection structure between the waist base 70, the thigh 44, and the large drape part 81. In addition, in order to facilitate understanding, a part is shown in perspective, and the connection structure between the waist base 70 and other hanging parts (left hanging part 85, right hanging part 86, buttocks hanging part 87) is omitted from the illustration. There is.

The waist base 70 has a substantially box-like shape that is long in the front-rear direction and the up-down direction, and has a ball stud 71 at its upper end for connecting to the abdomen 30 by a ball joint.
Further, a large link 72 is connected to the front upper part of the waist base 70 so as to be able to swing up and down. The rear joint of the Odari link 72 is connected to the waist base 70 by a link movable shaft 73 so as to be vertically swingable. Further, the front joint of the Odare link 72 is connected by an Odare movable shaft 74 at a bearing section 82 provided at the upper and lower intermediate portions of the back surface of the Odare part 81, so that the Odare part 81 can be swung up and down. I support it.

Thigh links 76 each having a ball stud 75 for connecting to the thigh 44 via a ball joint are connected to the left and right side surfaces of the waist base 70, respectively.
The front joint of the thigh link 76 is connected to the link movable shaft 73. The rear joint of the thigh link 76 is fitted into an arcuate guide groove 77 provided in the waist base 70. That is, the thigh link 76 is configured such that the rear joint portion can be vertically swung around the link movable shaft 73 along the guide grooves 77 on the left and right side surfaces of the waist base 70 .

In addition, when viewed from the front, the movable shaft (ball stud 75) for changing the angle of the thigh 44 (second part) with respect to the abdomen 30 (first part) is located at the large hanging part 81 (third part). It is configured to be provided below a movable shaft (large vertical movable shaft 74) for changing the direction of the movable shaft. In addition, when viewed from above, the movable axis (ball stud 75) for changing the angle of the thigh 44 is rearward of the movable axis (Odare movable axis 74) for changing the direction of the Odare part 81. It is located at a front-rear position closer to the center of the trunk (ball stud 71).

Next, with reference to FIGS. 16 to 19, a description will be given of the possible positional relationships of the parts around the waist 60 when the doll toy 2C is changed from an upright posture to a bent-knee and forward-bent posture. Note that in these figures, some parts are shown in perspective to facilitate understanding of relative positional relationships, and some parts are omitted from illustration.

FIG. 16 is a simplified sectional view showing the positional relationship of parts around the waist 60 when the doll toy 2C is in an upright position.
The abdomen 30 has a socket part 31 connected to the ball stud 71 in the internal space, and has an opening 32 at the front lower end into which the upper end of the large hanging part 81 can be inserted. However, in the upright position, the large hanging part 81 stands almost vertically, and its upper end is located close to the front surface of the abdomen 30 and covers the opening 32. Therefore, when the doll toy 2C is viewed from the front, the presence of the opening 32 is not noticeable, forming a continuous appearance from the chest 20 to the abdomen 30 to the waist 60 without a large gap. In addition, in the upright position, the lateral circumference of the waist portion 60 also forms a continuous appearance with a large unbroken line due to the exterior portion 80 (see FIG. 14).

From here, in order to make the doll toy 2C stand up and kneel, it is necessary to turn the thigh 44 (shown in a transparent state in FIGS. 16 to 19) forward, and the parts around the waist 60. transitions as shown in FIG. 17→FIG. 18→FIG. 19. That is, the thigh link 76 is swung about the link movable shaft 73 as the rotation axis, and the ball stud 75 is lowered to the front lower end of the waist base 70 . At the same time, the thigh 44 is placed in a sideways posture with its front surface facing upward.

In order to make the doll toy 2C bend forward, in parallel with changing the orientation of the thigh link 76 and the thigh 44, the angle formed by the abdomen 30 with the waist 60 is adjusted while changing the angle of the large drooping part 81. Change direction to reduce. In other words, the abdomen 30 is tilted forward.

Specifically, as shown in FIG. 16, in the large vertical link 72 in the upright position, the front joint is located above the link movable axis 73 and the ball stud 75. To bend forward from this point, first, as shown in FIGS. 17 to 18, the Odare link 72 is rotated about the link movable axis 73 so as to lower the front joint. Then, the swing axis of the Odare link 72 moves forward while lowering, and the swing axis of the Odare part 81 separates from the abdomen 30. This expands the interference prevention space Sp (see FIG. 18) between the abdomen 30 (first part) and the large hanging part 81 (third part).

From there, as shown in FIGS. 18 and 19, the upper end of the large hanging portion 81 is inclined toward the opening 32 of the abdomen 30. In addition, the abdomen 30 is tilted forward, and the upper end of the large hanging portion 81 is inserted into the internal space of the abdomen 30. As a result, while the abdomen 30 is largely bent forward, it is possible to form a continuous appearance from the abdomen 30 to the waist 60 without a large gap when viewed from the front. Note that a tapered surface T is provided at the upper end of the large hanging portion 81 (see FIGS. 15 and 16) to avoid contact with the opening 32 of the abdomen 30 when changing the direction of the large hanging portion 81. produce an effect.

The movement of the swinging position and the change in direction of the large hanging portion 81 have the effect of forming a continuous appearance with no large breaks in the appearance of the lateral circumference of the waist portion 60.
20 and 21 are simplified perspective views showing parts around the waist 60.
Assuming that the swing position of the Odare part 81 (front joint of the Odare link 72; Odare movable axis 74 (see FIG. 15)) cannot be changed as in this embodiment, the structure will be as shown in FIG. When the right thigh 44 is swung forward in order to make the doll toy 2C stand up and kneel, the right anterior drape 84 will also be swung upwards, but the large drape 81 will be raised when the doll toy 2C stands up and kneels. It remains in position, creating a large discontinuous part 9 in the right inguinal region. However, in this embodiment, as shown in FIG. 21, since the large flap part 81 can be laid down while being swung forward, a large cut can be made in the lateral circumference of the right anterior flap part 84 → the large flap part 81 → the left anterior flap part 83. It is possible to create an appearance that does not exist before, and it is possible to improve the design of the appearance.

According to the joint structure of the doll toy according to the embodiments described above, the second part (for example, the upper arm part 40 in FIG. 8, the thigh part 44 in FIG. 14) is connected to the first part (for example, the chest part in FIG. 8). 20, abdomen 30 in FIG. 81, left apron part 83, and right apron part 84) can be moved in accordance with the movement of the second part. For example, if the first part is the center chest, the second part is the arms, and the third part is the left and right chest, and you are trying to make a toy doll pose with its arms crossed in front of its chest, the arm movements will be different. In addition, the left and right chest (left and right parts of the chest) can be moved. In other words, the trunk (in this example, the entire chest), which was conventionally constructed as a single box, is divided into the first part and the third part, and the third part moves as the second part moves. By making it movable, the degree of freedom of movement of the joint can be increased. In addition, visually, the third part mediates between the first part and the second part, reducing the sense of discontinuity (a large gap in appearance) that connects the first part to the third part to the second part. Since it is possible to form an appearance that is unconventional, it is possible to suppress the reduction in attractiveness of the external design.

In addition, in the present embodiment, the first part and the third part partially overlap with each other, one on the outside and the other on the inside, when the third part rotates in a direction that reduces the angle formed. With this configuration, it is possible to avoid interference between the first part and the third part and create a continuous appearance with less sense of discontinuity in appearance.

Further, in the present embodiment, the third part has a tapered surface on the end closer to the first part to avoid contact with the first part during rotation. Even if the gap between the part and the third part is made small, interference between both parts can be reliably avoided. In addition, the tapered surface appropriately buffers the difference in angle between the outer surface of the first part and the outer surface of the third part, so that even if the first and third parts have a linear design, the appearance of both parts is continuous. can be made to look smoother.

Furthermore, in this embodiment, when viewed from above, the movable shaft for changing the angle of the second part (for example, the left arm ball stud 243 and the left shoulder shaft 244 in FIG. 3) changes the direction of the third part. The second part is arranged at a position farther from the center of the trunk than the movable axis (for example, the left swing axis 226 in FIG. 3) for the first part. Even in this configuration, a third part that makes an angle with the first part at a gentler angle than the angle that the second part makes with the first part can be placed between the first part and the second part. Therefore, when looking at the pose of the doll toy as a whole, the outer surface of the first part, the outer surface of the third part, and the outer surface of the second part are connected, so that the angle change of the outer surface becomes smoother and looks beautiful.

Further, in this embodiment, the first part is a part for the center of the chest, the second part is a part for the arms, and the third part is a part located on the left and right sides of the chest. By dividing the chest into at least three parts, the center and the left and right, it became possible to slump the shoulders forward, allowing one to hold a sword or gun by stretching both arms in front of the chest and folding the hands together. Now you can recreate cool poses with doll toys.

Further, in this embodiment, since the third part has a support portion that supports the second part, the third part can also serve as a support structure for the second part.

Furthermore, in this embodiment, when viewed from the front, a movable shaft for rotating the second part (for example, the ball stud 75 in FIGS. 14 and 15) is a movable shaft for rotating the third part. Since it is configured to be provided below the shaft (for example, the Odare movable shaft 74 in FIG. 15), even if the second part is arranged below the first part, the second part is located below the first part. A third part that forms an angle with the first part at a gentler angle than the angle formed with the other parts can be placed between the first part and the second part. Therefore, when looking at the pose of the doll toy as a whole, the angle change of the outer surface connecting from the outer surface of the first part to the outer surface of the third part to the outer surface of the second part becomes smoother and looks more beautiful.

Furthermore, in this embodiment, the third part has a portion above and a portion below a movable shaft (for example, the Odare movable shaft 74 in FIG. 15) for rotating the third part. , when the third part is rotated in a direction that reduces the angle formed, one of the upper part and the lower part of the third part moves to the outside of the first part, and the other part moves to the outside of the first part. Since it is configured to partially overlap the inside of the first part (for example, FIGS. 16 to 19), interference between the first part and the third part can be avoided, and the visual sense of continuity is reduced with less sense of discontinuity. It is possible to create a certain appearance.

Further, in this embodiment, the first part is an abdominal part (for example, the abdomen 30 in FIG. 14), and the second part is a leg part (for example, the thigh part 44 in FIG. 14). The third part is a part for the appearance of the waist (for example, the large hanging part 81 in FIG. 14), and as a result, the third part can be changed depending on the position of the second part, the leg part. You can change the position of the waist appearance parts. Therefore, for example, in response to a kneeling pose, appearance parts around the waist can be changed to appropriate positions to achieve a natural and good-looking appearance.

Further, in this embodiment, the third part is configured to swing relative to the first part, one end supporting the swing shaft of the third part, and the other end supporting the swing shaft of the third part. further comprising a link part (for example, the large link 72 in FIG. 15), and by swinging the link part up and down about the other end, the swing axis of the third part is positioned vertically. Since it is configured to be adjustable, the position of the swing axis of the third part (for example, the large hanging portion 81 in FIG. 14) can be changed. Therefore, it is possible to expand the changeable posture and position of the third part and contribute to realizing various poses of the doll toy.

Further, in this embodiment, when the second part is rotated so as to reduce the formed angle, interference between the first part and the third part is prevented by swinging the link part downward. Since the structure allows the space to be expanded, the link part swings downward as the second part rotates, thereby moving the entire third part away from the first part to prevent interference. Space expands. The expansion of the interference prevention space means the expansion of the room for changing the third part to a position where it does not interfere with the first part, and it is easier to change the orientation of the third part in a direction that reduces the angle formed with the first part. Become. As a result, when looking at the doll toy as a whole, the angle formed by the third part with respect to the first part can be made smaller.
