Description

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

Doll toys are known that can be played in various poses by assembling parts for each part. For example, Patent Document 1 discloses a joint mechanism of a doll toy in which a connecting portion such as a shoulder is formed of a soft material and the movable region is widened by deforming or bending.

Registered Utility Model Gazette No. 3185443

By the way, as one of the design themes of doll toys, the design of humanoid robots is known. In doll toys designed as humanoid robots, the main trunks such as the chest, abdomen, and waist are often linear and mechanically designed covered with armor, and traditionally those trunk parts are one box-shaped part. Has been designed as. Therefore, inconvenience was likely to occur in the movement of the movable part provided on the trunk.

Specifically, for example, in hero TV anime and manga, poses that hold a sword or gun with both hands extended in front of the chest often appear, so users definitely want to reproduce it with doll toys. I hope. However, if the chest is designed as one box as in the conventional case, the position of the shoulder portion of the upper arm connected to the shoulder joint is almost fixed. Therefore, even if you try to pose with your arms extended forward, the position of the shoulders remains the same and only the arms bend forward, resulting in a so-called "forward-looking" pose. In some cases, it was possible to combine both hands by bending the elbow joint with the arm facing forward, but doing so would result in an awkward "position", which is far from the original "position" for extending the arm. rice field. In any case, the hope was not fulfilled.

It is considered that the above-mentioned "stance" may be realized by using the joint mechanism using the soft material disclosed in Patent Document 1. However, if the wrinkles and deflections of the soft material are visible, the original attractiveness of the exterior design will be impaired, although the "stance" itself can be achieved. In addition, the above-mentioned "stance" cannot be maintained because the bent soft material tries to be restored.

The above-mentioned problem of "stance" is an example, and it is a problem that occurs when the joint portion is bent greatly (or deeply) even in other joint portions.
An object of the present invention is to provide a technique capable of increasing the degree of freedom of movement of a joint portion while suppressing a decrease in attractiveness of an appearance design.

The joint structure of the doll body according to the present invention is the joint structure of the doll body, and constitutes the first part (for example, the chest 20 in FIG. 8 and the abdomen 30 in FIG. 14) constituting the trunk and the limbs. A second part that is rotatable with respect to the first part (for example, the upper arm portion 40 in FIG. 8 and the thigh portion 44 in FIG. 14) constitutes a part of the trunk or the appearance of the trunk, and the first part is formed. It is a third part that is rotatable with respect to the above, and when it is rotated so as to reduce the angle formed by the second part and the first part, it is formed in accordance with the rotation of the second part. A third part (for example, the left chest part 24 and the right chest part 26 of the chest 20 of FIG. 8, the large hanging part 81 of FIGS. 14 and 21, and the left front hanging) configured to be rotatable in a direction of reducing the angle. A portion 83 and a right anterior hanging portion 84) are provided.

Further, in the present invention, the first part and the third part partially overlap each other on the outside and the other on the inside when the third part rotates in a direction to reduce the angle formed by the first part and the third part. It may be configured.

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

Further, in the present invention, the movable shaft for changing the angle of the second part (for example, the ball stud 243 for the left arm and the left shoulder shaft 244 in FIG. 3) in the top view is for changing the direction of the third part. It may be provided at a position farther from the center of the trunk than the movable shaft (for example, the left swing shaft 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 arm, 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 have a support portion for supporting the second part.

Further, in the present invention, the movable shaft for rotating the second part (for example, the ball stud 75 in FIGS. 14 and 15) is the movable shaft for rotating the third part (for example, in the front view). For example, it may be provided below the large hanging movable shaft 74) in FIG.

Further, in the present invention, the third part has a portion above and a portion below the movable shaft for rotating the third part (for example, the large hanging movable shaft 74 in FIG. 15). 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 is outside the first part, and the other is the first part. It may be configured to partially overlap the inside of the part (eg, FIGS. 16-19).

Further, in the present invention, the first part is a part for the abdomen (for example, the abdomen 30 in FIG. 14), and the second part is a part for the legs (for example, the thigh portion 44 in FIG. 14). The third part may be a part for the appearance of the waist (for example, the large hanging portion 81 in FIG. 14).

Further, in the present invention, the third part is configured to swing with respect to the first part, one end of which supports the swing shaft of the third part, and the other end of the link is pivotally supported. A part (for example, the large hanging link 72 in FIG. 15) is further provided, and the swing axis of the third part can be adjusted up and down by swinging the link part up and down with the other end as the axis center. It may be configured in.

Further, in the present invention, when the second part is rotated so as to reduce the angle formed, the link part is swung downward to prevent interference between the first part and the third part. May be configured so that it can be expanded.

[First Embodiment]
FIG. 1 is a perspective external view of an upper body portion of a doll toy according to the first embodiment.
The doll toy 2 is a toy configured by assembling parts for each part. In the illustrated example, each part of the head 10 of the doll toy 2, the chest 20, the abdomen 30, the upper arm 40, and the back sac 50 is selectively shown, but the parts not shown are shown. Parts are also provided as appropriate (for example, lower arm, waist, leg, etc.). The user can arbitrarily change the relative orientation and the relative posture of each of these parts, and can enjoy various poses of the doll toy 2.

The chest 20 of the present embodiment has 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 in the present embodiment, forms the left and right central parts of the chest 20. The left chest part 24 and the right chest part 26 are a part of the trunk or a third part constituting the appearance of the trunk. In this embodiment, the right half body corresponding to the right shoulder and the right lung portion and the left half body corresponding to the left shoulder and the left lung portion are formed, 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 connected appearance as the chest 20.

FIG. 2 is a front view of the doll toy 2 in the present embodiment, and includes a partial cross-sectional view in which the front side of the left chest part 24 is cut.
FIG. 3 is a front view exploded view of the doll toy 2 in the present embodiment, and includes a partial cross-sectional view in which the front side of the left chest part 24 is cut.
FIG. 4 is a top view of the doll toy 2 of the present embodiment.

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

The left chest part 24 and the right chest part 26 are symmetrical to each other in this embodiment. Hereinafter, the left chest part 24 will be described as a representative.
The left chest part 24 is a box-shaped body that opens to the right and downward, and has a left exterior portion 241 that forms a partial appearance of the front, side, back, and upper surface of the left half of the chest, and a left swing shaft 226. It has a left bearing 242 through which the left upper arm portion 40 (second part) is inserted vertically, and a left arm ball stud 243 for connecting the left upper arm portion 40 (second part) with a ball joint. The ball stud 243 for the left arm forms the upper front and rear center upper surface of the left half of the chest, and is pivotally supported by a left shoulder shaft 244 provided in the left exterior portion 241 so as to extend in the front-rear direction. That is, the doll toy 2 can pose to raise the left shoulder by swinging the ball stud 243 for the left arm in the vertical direction on the left shoulder axis 244.

In the present embodiment, the movable shaft (ball stud 243 for the left arm, left shoulder shaft 244) for changing the angle of the upper arm portion 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 shaft (left swing shaft 226) for doing so (see FIG. 3). Further, 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 the present embodiment, the left chest part 24 is assembled to the lower part 222 from above so that the left swing shaft 226 is inserted into the left bearing 242. Has been done. Then, in the same manner, the right chest part 26 is assembled to the lower part 222 from above so that the right swing shaft 227 is inserted into the right bearing. Further, the upper part 221 is assembled from above the left chest part 24 and the right chest part 26. The upper arm 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 portion 223.
Therefore, as shown in FIG. 4, the tip of the right end of the left chest part 24 is inserted inward from the left opening of the central chest part 22, and the tip of the left end of the right chest part 26 is inserted. Is inserted inward from the right opening of the central chest part 22.

FIG. 5 is a cross-sectional view taken along the line AA of FIG. 2, which is a cross-sectional view when both shoulders are turned backward. As shown in FIG. 5, the doll toy 2 in the present embodiment can be made to pose with both shoulders bent backwards to stretch the chest.
That is, the direction of the left chest part 24 is changed around the left swing axis 226 so that the angle formed by the rear surface of the central chest part 22 constituting the trunk and the rear surface of the left chest part 24 is reduced. Can be done. As a result, the ball stud 243 for the left arm rotates backward, and the front surface of the chest 20 is deformed so as to be substantially curved so as to form a convex toward the front, and a pose as if the chest is stretched is completed.

At this time, the front side of the left chest part 24 and the end near the center chest part 22 are shaped so that the part inserted inside the center chest part 22 is pulled out as the direction is changed, and the left chest part 24 and the center. It is difficult to create a gap between the chest part 22 and the chest part 22. This preferably keeps the continuous appearance of the chest 20. The same is true between the right chest part 26 and the central chest part 22.

Further, tapered surfaces T are provided at the ends of the left chest part 24 near the center chest part 22 and the ends of the right chest part 26 near the center of the chest, respectively, with respect to the center chest part 22. When changing the orientation, it avoids contact with the central chest part 22 and creates a smooth connection on the outer surface. The shape of the tapered surface T is not limited to a linear slope surface, and may be formed by a curved surface composed of a rotating body centered on the swing shafts 226 and 227, and avoids contact with the central chest part 22. It may be formed by a free curved surface having a reduced volume.

FIG. 6 is a cross-sectional view taken along the line AA of FIG. 2, which is a cross-sectional view when both shoulders are turned forward. As shown in FIG. 6, the doll toy 2 in the present embodiment can be made to pose with both shoulders squeezed forward.
That is, the direction of the left chest part 24 is changed around the left swing axis 226 so that the angle formed by the front surface of the central chest part 22 constituting the trunk and the front surface of the left chest part 24 is reduced. Can be done. As a result, the ball stud 243 for the left arm rotates forward and deforms so that the width of the front of the chest 20 in the left-right direction becomes narrow, and a pose as if the shoulder is squeezed forward is completed. At this time, the end portion of the left chest part 24 near the front central chest part 22 is inserted further inward of the central chest part 22 as the direction is changed. As a result, when trying to pose as if the shoulders are squeezed forward, the volume in front of the chest formed by the left chest part 24 and the central chest part 22 becomes small, so that the movement of the upper arm 40 is not hindered. By doing so, it is possible to preferably maintain the continuous appearance of the chest 20 while expanding the movable range of the upper arm 40. The same is true between the right chest part 26 and the central chest part 22.

By being able to pose with both shoulders squeezed forward, the doll toy 2 in the present embodiment can be made to pose in a more diverse and natural manner.
Specifically, for example, as shown in FIG. 7, the chest 20 is formed in a substantially box shape like a conventional doll toy (central chest part 22, left chest part 24, right chest part). In the case of (there is no split configuration such as 26), both shoulders cannot be squeezed forward, so even if both arms are turned forward (lower side of Fig. 7), the so-called "front" I can only do 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 the present embodiment, both shoulders are squeezed forward. With both arms facing forward, you can pose as if you were folding in front of your chest with your arms extended. For example, you will be able to reproduce a good-looking pose with a gun in front of you.

Moreover, the movable axes (left swing axis 226, right swing axis 227) of the left chest part 24 and the right chest part 26 are the ball studs 243, which are the movable axes 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 of the impression that the central chest part 22, the left chest part 24, and the right chest part 26 are connected as a chest.

Further, the point where the left swing shaft 226 and the right swing shaft 227 are provided near the back surface with respect to the center line L2 in the front-back direction of the chest 20 (see FIG. 4) is when the shoulder is swung forward. By increasing the radius of gyration of the ends of the left chest part 24 and the right chest part 26 near the center chest part 22, the tapered surface for avoiding interference with the center chest part 22 is made smaller. The central chest part 22, the left chest part 24, and the right chest part 26 contribute to realizing a top view of the impression that the chest is connected.

[Second Embodiment]
Next, a second embodiment to which the present invention is applied will be described. In the following, the differences from the first embodiment will be mainly described, and the same reference numerals will be given to the same components as those of the first embodiment, and duplicate explanations will be omitted as appropriate.

FIG. 9 is a front view of the upper body portion showing a configuration example of the doll toy 2B in the present embodiment.
FIG. 10 is a partial cross-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 to the left and right, and the upper part 221B and the 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 cover the left and right openings of the central chest part 22B, respectively. That is, the right end of the left chest part 24B covers the outside of the left opening of the central chest part 22B, and the left end of the right chest part 26B covers the outside of the right opening of the central chest part 22B. It constitutes an integrated and continuous appearance as.

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 in this embodiment. Further, 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 the present embodiment. That is, the degree of freedom of the shoulder and the arm of the doll toy 2B of the present embodiment is higher than that of the first embodiment.

Naturally, the doll toy 2B in the present embodiment can also have the same effect as the first embodiment by making the pose of purging both shoulders forward as in the first embodiment.
That is, assuming that the chest 20B is formed in one substantially box shape (assuming that the central chest part 22B, the left chest part 24B, and the right chest part 26B are not divided into an integrated structure). ), As shown in FIG. 12, since both shoulders cannot be squeezed forward, even if both arms are turned forward (lower side of FIG. 12), only the so-called "forward-looking" posture is possible.

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 that both shoulders are squeezed forward and both arms are forward. When turned, it is possible to pose with both arms extended in front of the chest. For example, you will be able to reproduce cool poses such as holding a sword in front of your chest.

Further, in the present embodiment, since 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, the shoulders are not only in the front but also in the front diagonally downward direction. It can also be deflated diagonally forward, diagonally upward, overhead, backward diagonally upward, and backward diagonally downward. 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 connected appearance as the chest 20.

[Third Embodiment]
Next, a third embodiment to which the present invention is applied will be described. In the following, the differences from the first and second embodiments will be mainly described, and the same reference numerals will be given to the same components as those of the first and second embodiments, and duplicate explanations will be omitted as appropriate. do.

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

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

The exterior portion 80 has a large hanging portion 81 that integrally covers the front surface of the lumbar region 60 from the umbilical region to the crotch, and a left anterior hanging portion that is connected to the upper end of the large hanging portion 81 by a ball joint and covers the front of the left and right thigh joints. It includes a portion 83 and a right anterior hanging portion 84, a left hanging portion 85 and a right hanging portion 86 covering the left and right side surfaces of the lumbar portion 60, and an umbilical region 87 (see FIG. 17) covering the rear of the lumbar portion 60. The left side hanging portion 85 and the right side hanging portion 86 are swingably supported by the horizontal axis in the front-rear direction with respect to the waist base 70 at the upper end portions thereof, and the lower ends are swingably connected to each other.

FIG. 15 is a perspective exploded view showing an example of a connection configuration of the waist base 70, the thigh 44, and the thigh 81. In addition, in order to facilitate understanding, a part of the waist base 70 is shown through fluoroscopy, and the connecting structure between the waist base 70 and other hanging parts (left side hanging part 85, right side hanging part 86, buttocks hanging part 87) is not shown. There is.

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

A thigh link 76 having a ball stud 75 for connecting to the thigh 44 with a ball joint is connected to the left and right side surfaces of the waist base 70, respectively.
The anterior 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 the arc-shaped guide groove 77 provided in the waist base 70. That is, the thigh link 76 can swing the rear joint portion up and down along the guide grooves 77 on the left and right side surfaces of the waist base 70 around the link movable shaft 73.

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 the large hanging portion 81 (third part). It is configured to be provided below the movable shaft (large hanging movable shaft 74) for changing the direction of. Further, when viewed from above, the movable shaft (ball stud 75) for changing the angle of the thigh portion 44 is behind the movable shaft (large hanging movable shaft 74) for changing the direction of the large hanging portion 81. It is located in the front and rear positions closer to the center of the trunk (ball stud 71).

Next, with reference to FIGS. 16 to 19, the positional relationship that the parts around the waist 60 can take when the doll toy 2C is changed from the upright posture to the standing knee and the forward bending posture will be described. In these figures, some parts are shown in perspective to facilitate understanding of the relative positional relationship, and some parts are omitted from the illustration.

FIG. 16 is a simplified cross-sectional view showing the positional relationship of the parts around the waist 60 in a state where the doll toy 2C is in an upright posture.
The abdomen 30 has a socket portion 31 internally connected to the ball stud 71 in the internal space, and has an opening 32 at the lower end on the front side into which the upper end of the large hanging portion 81 can be inserted. However, the large hanging portion 81 in the upright posture is in a posture of standing up and down, and the upper end thereof 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 inconspicuous, forming a large continuous appearance from the chest 20 to the abdomen 30 to the waist 60. In the upright posture, the lateral circumference of the lumbar portion 60 also forms a continuous appearance without a large break due to the exterior portion 80 (see FIG. 14).

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

Then, in order to make the doll toy 2C bend forward, in parallel with the change of the directions of the thigh link 76 and the thigh 44, the angle forming the abdomen 30 with respect to the waist 60 while changing the angle of the thigh 81 is formed. Turn around to reduce. That is, the abdomen 30 is tilted forward.

Specifically, as shown in FIG. 16, in the large hanging link 72 in the upright posture, the front joint is above the link movable shaft 73 and the ball stud 75. To bend forward from here, first, as shown in FIGS. 17 to 18, the large hanging link 72 is rotated around the link movable shaft 73 so as to lower the front joint. Then, the swing axis of the large drop link 72 moves forward while descending, and the swing axis of the large drop portion 81 separates from the abdomen 30. As a result, the interference prevention space Sp (see FIG. 18) between the abdomen 30 (first part) and the large hanging part 81 (third part) is expanded.

From there, as shown in FIGS. 18 → 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 so that the upper end of the large hanging portion 81 is inserted into the internal space of the abdomen 30. As a result, it is possible to form a large, continuous and continuous appearance from the abdomen 30 to the waist 60 when viewed from the front while greatly bending the abdomen 30 forward. 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 of the direction of the large hanging portion 81 also bring about the effect of forming a large, continuous and continuous appearance of the lateral circumference of the lumbar portion 60.
20 and 21 are simplified perspective views showing parts around the waist 60 extracted.
Assuming that the swing position of the large hanging portion 81 (the front joint of the large hanging link 72; the large hanging movable shaft 74 (see FIG. 15)) cannot be changed as in the present embodiment, as shown in FIG. In addition, when the right thigh 44 is swung forward in order to make the doll toy 2C stand and kneel, the right anterior hanging portion 84 is also swung up, but the large hanging portion 81 is in an upright posture. The position remains, and a large appearance break 9 is formed in the right inguinal region. However, in the present embodiment, as shown in FIG. 21, since the large hanging portion 81 can be laid down while being swung forward, a large cut is made in the lateral circumference of the right front hanging portion 84 → the large hanging portion 81 → the left front hanging portion 83. It is possible to form a non-existent appearance and improve the design of the appearance.

According to the joint structure of the doll toy according to the embodiment described above, the second part (for example, the upper arm 40 in FIG. 8 and the thigh 44 in FIG. 14) is the first part (for example, the chest in FIG. 8). 20, the left chest part 24 and the right chest part 26, FIG. 14 and FIG. 21 of the chest 20 of FIG. 8 when moving to reduce the angle formed with respect to the abdomen 30 of FIG. The large hanging portion 81, the left front hanging portion 83, and the right front hanging portion 84) can be moved according to the movement of the second part. For example, when the first part is the central chest, the second part is the arm, and the third part is the left and right chest, and the doll toy is made to pose with the arms sticking out in front of the chest, the movement of the arm In addition, the left and right chests (left and right parts of the chest) can be moved. In other words, the trunk (the entire chest in this example), which was conventionally configured as one box, is divided into the first part and the third part, and the third part is also configured according to the movement of the second part. By making it movable, the degree of freedom of movement of the joint can be increased. In addition, in terms of appearance, the third part holds between the first part and the second part, so that there is a sense of discontinuity (a large break in appearance) that connects the first part to the third part to the second part. Since it is possible to form a series of appearances that do not exist, it is possible to suppress the reduction of attractiveness of the appearance design.

Further, in the present embodiment, the first part and the third part partially overlap each other on the outside and the other on the inside when the third part rotates in a direction to reduce the angle formed by the first part and the third part. By configuring in this way, it is possible to form a continuous appearance with less apparent discontinuity while avoiding interference between the first part and the third part.

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

Further, in the present embodiment, in the top view, the movable shaft for changing the angle of the second part (for example, the ball stud 243 for the left arm and the left shoulder shaft 244 in FIG. 3) changes the direction of the third part. Since the movable shaft (for example, the left swing shaft 226 in FIG. 3) is provided at a position farther from the center of the trunk, the second part is arranged on the side of the first part. Even in the configuration, the third part, which forms an angle with the first part at an angle gentler than the angle formed by the second part with respect to the first part, can be arranged between the first part and the second part. Therefore, when the pose of the doll toy as a whole is viewed, it is connected to the outer surface of the first part, the outer surface of the third part, and the outer surface of the second part, so that the angle change of the outer surface becomes smoother and looks beautiful.

Further, in the present embodiment, the first part is a part for the center of the chest, the second part is a part for the arm, 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 is possible to squeeze the shoulders forward, holding the sword or gun with both arms extended in front of the chest. You will be able to reproduce cool poses with doll toys.

Further, in the present embodiment, since the third part has a support portion for supporting the second part, the support structure of the second part can be combined with the third part.

Further, in the present embodiment, in the front view, the movable shaft for rotating the second part (for example, the ball stud 75 in FIGS. 14 and 15) is movable for rotating the third part. Since it is provided below the shaft (for example, the large hanging movable shaft 74 in FIG. 15), the second part is the first part even if the second part is arranged below the first part. A third part that forms an angle with the first part can be placed between the first part and the second part at an angle that is gentler than the angle formed with respect to the part. Therefore, when the pose of the doll toy as a whole is viewed, the angle change of the outer surface connected to the outer surface of the first part, the outer surface of the third part, and the outer surface of the second part becomes smoother and looks beautiful.

Further, in the present embodiment, the third part has a portion above and a portion below the movable shaft (for example, the large hanging 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 is outside the first part, and the other is said. Since it is configured so as to partially overlap the inside of the first part (for example, FIGS. 16 to 19), there is little discontinuity in appearance while avoiding interference between the first part and the third part, and the feeling of continuity is small. Can form a certain appearance.

Further, in the present embodiment, the first part is a part for the abdomen (for example, the abdomen 30 in FIG. 14), and the second part is a part for the legs (for example, the thigh portion 44 in FIG. 14). The third part is a part for the appearance of the waist (for example, the large hanging portion 81 in FIG. 14), whereby the third part is changed according to the position change of the leg portion which is the second part. The position of the waist exterior parts can be changed. Therefore, for example, the appearance parts around the waist can be changed to appropriate positions according to the pose of the standing knee, and a natural and good-looking appearance can be realized.

Further, in the present embodiment, the third part is configured to swing with respect to the first part, one end portion supports the swinging shaft of the third part, and the other end portion is pivotally supported. The link part (for example, the large hanging link 72 in FIG. 15) is further provided, and the swing axis of the third part is positioned up and down by swinging the link part up and down with the other end as the axis center. Since it is configured to be adjustable, the position of the swing shaft 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 the realization of various poses of the doll toy.

Further, in the present embodiment, when the second part is rotated so as to reduce the angle formed, the link part is swung downward to prevent interference between the first part and the third part. Since the space can be expanded, the link part swings downward as the second part rotates, and the entire third part is moved away from the first part to prevent interference. The space expands. The expansion of the interference prevention space is an expansion of the room for changing the third part to a position where it does not interfere with the first part, and it is easy to change the direction of the third part in the direction of reducing the angle formed with respect to the first part. Become. As a result, the angle formed by the third part with respect to the first part can be made smaller for the doll toy as a whole.
