Joint structure for doll body

Abstract

To provide a technique by which the degree of freedom of movability in joints can be enhanced while reduction of attractiveness in appearance design is suppressed.SOLUTION: A chest 20 of a toy doll 2 is separately structured with a central chest part 22 and a left chest part 24 and a right chest part 26 that can oscillate frontward and rearward relative to the central chest part 22. The left chest part 24 and the right chest part 26 each support the upper arm 40, with their ends inserted inside the central chest part 22 to form a continuous external appearance. The upper arm 40 as well as the left chest part 24 and the right chest part 26 can be oriented forward. Thus, an attractive pose can be reproduced in the toy doll 2 by sticking both arms to the front while hunching the shoulders to the front.SELECTED DRAWING: Figure 8

Description

[Technical field]

[0001] The present invention relates to a joint structure of a doll body. [Background technology]

[0002] There are known doll toys that are constructed by assembling different parts for different body parts and can be played with in various poses. For example, Patent Document 1 discloses a joint mechanism for a doll toy in which the joint parts such as the shoulders are made of soft material and can be deformed or bent to expand the range of motion. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Registered Utility Model Publication No. 3185443 Summary of the Invention [Problem to be solved by the invention]

[0004] Now, one of the design themes of doll toys is the design of humanoid robots. In doll toys designed as humanoid robots, the main trunks such as the chest, abdomen, and waist are often covered with armor and have a linear, mechanical design, and traditionally these trunk parts have been designed as a single box-shaped part. This has made it easy for the movable parts on the trunk to have difficulty moving.

[0005] Specifically, for example, in superhero TV anime and manga, a pose where the hands are stretched out in front of the chest and clasped together to hold a sword or a gun is often seen, and users would love to recreate that with a doll toy. However, if the chest is designed as a single box-shaped body as in the past, the position of the shoulder part of the upper arm connected to the shoulder joint is almost fixed. Therefore, even if you try to make a pose where the arms are stretched out widely forward, the position of the shoulder part remains the same and only the arms bend forward, resulting in a so-called "standing forward" pose. Also, in some cases it was possible to clasp the hands by pointing the arms forward and bending the elbow joint, but this resulted in an awkward "pose" that was far removed from the original "pose" of stretching the arms. Either way, the wish was not fulfilled.

[0006] It is thought that the above-mentioned "pose" could be realized by using the joint mechanism using the soft material disclosed in Patent Document 1. However, if the wrinkles and bending of the soft material are visible, the original appeal of the external design will be lost, even though the "pose" itself can be achieved. In addition, the bent soft material will try to return to its original shape, so the above-mentioned "pose" cannot be maintained.

[0007] The above-mentioned "posture" problem is just one example, and problems also occur with other joints when the joints are bent significantly (or deeply). An object of the present invention is to provide a technology that can increase the degree of freedom of movement of a joint while minimizing the loss in the attractiveness of the exterior design. [Means for solving the problem]

[0008] The joint structure of a doll body according to the present invention is a joint structure of a doll body, comprising: a first part constituting a trunk (for example, chest 20 in FIG. 8 and abdomen 30 in FIG. 14); a second part constituting a limb and rotatable relative to the first part (for example, upper arm 40 in FIG. 8 and thigh 44 in FIG. 14); and a third part constituting a part of the trunk or the exterior of the trunk and rotatable relative to the first part, which, when rotated to reduce the angle between the second part and the first part, is configured to be rotatable in a direction that reduces the angle in accordance with the rotation of the second part (for example, left chest part 24 and right chest part 26 of chest 20 in FIG. 8; larger hanging part 81, left front hanging part 83, and right front hanging part 84 in FIGS. 14 and 21).

[0009] In addition, the present invention may be configured such that the first part and the third part overlap with one part on the outside and the other part on the inside when the third part is rotated in a direction to reduce the angle they form.

[0010] In the present invention, the third part may have a tapered surface at an end portion closer to the first part, for avoiding contact with the first part during rotation.

[0011] In addition, in the present invention, when viewed from above, a movable axis for changing the angle of the second part (e.g., left arm ball stud 243 and left shoulder axis 244 in FIG. 3) may be provided at a position farther from the center of the trunk than a movable axis for changing the orientation of the third part (e.g., left swing axis 226 in FIG. 3).

[0012] 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.

[0013] In the present invention, the third part may have a support portion that supports the second part.

[0014] In addition, in the present invention, when viewed from the front, the movable axis for rotating the second part (e.g., ball stud 75 in Figures 14 and 15) may be configured to be located lower than the movable axis for rotating the third part (e.g., large vertical movable axis 74 in Figure 15).

[0015] Furthermore, in the present invention, the third part may have a portion above and a portion below a movable axis (e.g., large vertical movable axis 74 in FIG. 15) for rotating the third part, and may be configured such that, when the third part is rotated in a direction that reduces the angle, one of the upper portion and the lower portion of the third part partially overlaps with the outside of the first part, and the other partially overlaps with the inside of the first part (e.g., FIGS. 16 to 19).

[0016] In addition, in the present invention, the first part may be a part for the abdomen (e.g., abdomen 30 in FIG. 14), the second part may be a part for the legs (e.g., thighs 44 in FIG. 14), and the third part may be a part for the appearance of the waist (e.g., upper abdomen 81 in FIG. 14).

[0017] In addition, in the present invention, the third part may be configured to swing relative to the first part, and may further include a link part (e.g., large vertical link 72 in FIG. 15) having one end supporting the swing axis of the third part and the other end pivotally supported, and the link part may be swung up and down around the other end as an axis center, thereby making it possible to adjust the position of the swing axis of the third part up and down.

[0018] In addition, the present invention may be configured so that when the second part is rotated so as to reduce the angle, the link part can be swung downward to expand the interference prevention space between the first part and the third part. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] [First embodiment] FIG. 1 is a perspective external view of the upper body of a doll toy according to a first embodiment. The doll toy 2 is a toy that is constructed by assembling parts for different body parts. In the illustrated example, the head 10, chest 20, abdomen 30, upper arms 40, and backpack 50 of the doll toy 2 are selectively illustrated, but parts for other body parts not illustrated (for example, lower arms, waist, legs, etc.) are also provided as appropriate. The user can freely change the relative orientations and postures of these parts, and enjoy changing the poses of the doll toy 2 in various ways.

[0021] The chest 20 in this 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 this embodiment, forms the left-right central portion of the chest 20. The left chest part 24 and the right chest part 26 are third parts constituting a part of the trunk or the external appearance of the trunk. In this embodiment, they form the right half corresponding to the right shoulder and right lung, and the left half corresponding to the left shoulder and left lung, respectively. The outer surfaces of the central chest part 22, the left chest part 24, and the right chest part 26 form the external appearance of the chest 20, which is integrally connected.

[0022] FIG. 2 is a front view of the doll toy 2 in this embodiment, and includes 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, and includes a partial cross-sectional view of the left chest part 24 cut away from the front side. FIG. 4 is a top view of the doll toy 2 of the present embodiment.

[0023] As shown in FIG. 3, the central chest part 22 of this embodiment is bilaterally symmetrical, and has an upper part 221 and a lower part 222. The upper part 221 is a generally box-shaped body that is open on the left, right and bottom sides, and forms the top surface, central front and central back surface of the chest part 20. The upper part has a joint part 223 for connecting the ball joint 12 that connects the head part 10. The lower part 222 has a bottom surface 224 of the chest 20 that connects to the abdomen 30, a joint connecting column part 225 that connects to the joint part 223, a left swing shaft 226 that connects the left chest part 24 so that it can rotate freely left and right, and a right swing shaft 227 that supports the right chest part 26 so that it can rotate freely left and right.

[0024] In this embodiment, the left chest part 24 and the right chest part 26 are symmetrical to each other. In the following, the left chest part 24 will be described as a representative example. The left chest part 24 is a box-shaped body that opens to the right and downward, and has a left exterior part 241 that forms the outer appearance of the front, side, back and part of the top of the left chest half, a left bearing 242 through which the left swing shaft 226 is inserted vertically, and a left arm ball stud 243 for connecting the left upper arm 40 (second part) with a ball joint. The left arm ball stud 243 forms the upper surface in the center of the front and rear of the left chest half, and is supported vertically swingably by a left shoulder shaft 244 that is provided inside the left exterior part 241 and extends in the front and rear direction. In other words, the doll toy 2 can be posed with the left shoulder raised by swinging the left arm ball stud 243 vertically using the left shoulder shaft 244.

[0025] In this embodiment, the movable axis (left arm ball stud 243, left shoulder axis 244) for changing the angle of the upper arm 40 (second part) is provided at a position farther from the center line L1 of the trunk than the movable axis (left swing axis 226) for changing the orientation of the left chest part 24 (third part) (see FIG. 3). In addition, when viewed from above, the left swing axis 226 is erected at a position closer to the back of the chest with respect to the front-to-back center line L2 of the chest 20 (see FIG. 4).

[0026] 3, in the upper body of the doll toy 2 of this embodiment, the left chest part 24 is assembled to the lower part 222 from above by inserting the left swing shaft 226 into the left bearing 242. Similarly, the right chest part 26 is assembled to the lower part 222 from above by inserting the right swing shaft 227 into the right bearing. Furthermore, the upper part 221 is assembled from above the left chest part 24 and the right chest part 26. Then, the upper arms 40 are assembled to the left chest part 24 and the right chest part 26, respectively, and the head 10 is assembled to the joint part 223. Therefore, as shown in FIG. 4, the tip of the right end of the left chest part 24 is inserted into the inside of the left opening of the central chest part 22, and the tip of the left end of the right chest part 26 is inserted into the inside of the central chest part 22 through its right opening.

[0027] Fig. 5 is a cross-sectional view taken along line AA in Fig. 2, showing a cross-sectional view in which both shoulders are turned backward. As shown in Fig. 5, the doll toy 2 in this embodiment can be posed with both shoulders turned backward and chest out. That is, the orientation of the left chest part 24 can be changed around the left swing axis 226 so that the angle between the rear surface of the central chest part 22 that constitutes the trunk and the rear surface of the left chest part 24 is reduced. As a result, the left arm ball stud 243 rotates backward and the front surface of the chest 20 is deformed so as to be curved so as to form a convex shape toward the front, creating a pose as if the chest is puffed out.

[0028] At this time, the end of the left chest part 24 on the front side and closest to the central chest part 22, which was inserted inside the central chest part 22, is pulled out as it turns, making it difficult for a gap to form between the left chest part 24 and the central chest part 22. This maintains a good connected appearance of the chest 20. The same can be said for between the right chest part 26 and the central chest part 22.

[0029] Additionally, a tapered surface T is provided on the end of the left chest part 24 closer to the central chest part 22, and on the end of the right chest part 26 closer to the center of the chest, which avoids contact with the central chest part 22 when changing the orientation relative to the central chest part 22 and creates a smooth connection of the outer surface. The shape of the tapered surface T is not limited to a linearly inclined surface, but may be formed as a curved surface consisting of a body of revolution about the pivot axes 226, 227, or may be formed as a free-form surface with a reduced volume to avoid contact with the central chest part 22.

[0030] Fig. 6 is a cross-sectional view taken along line AA in Fig. 2, showing a cross-sectional view in which both shoulders are turned forward. As shown in Fig. 6, the doll toy 2 in this embodiment can be posed with both shoulders hunched forward. That is, the orientation of the left chest part 24 can be changed around the left swing axis 226 so that the angle between the front of the central chest part 22 and the front of the left chest part 24, which constitute the trunk, is reduced. As a result, the left arm ball stud 243 rotates forward, and the width of the front of the chest 20 in the left-right direction is narrowed, creating a pose as if the shoulders are hunched forward. At this time, the end of the left chest part 24 near the front central chest part 22 is inserted further inward into the central chest part 22 as the orientation is changed. As a result, when trying to create a pose as if the shoulders are hunched forward, the volume of the front of the chest formed by the left chest part 24 and the central chest part 22 becomes smaller, and the movement of the upper arm 40 is not hindered, so that the movable range of the upper arm 40 can be expanded while maintaining a suitable appearance of the connected chest 20. The same can be said about the relationship between the right chest part 26 and the central chest part 22.

[0031] By being able to pose the doll with both shoulders hunched forward, the doll toy 2 in this embodiment can be made to take more diverse and natural poses. Specifically, for example, as shown in FIG. 7, if the chest 20 were formed into a single, roughly box-like shape like a conventional doll toy (rather than being divided into a central chest part 22, a left chest part 24, and a right chest part 26), the shoulders would not be able to be hunched forward, so even if the arms were pointed forward (to the bottom of FIG. 7), the only posture that could be achieved would be the so-called "stand in front" posture.

[0032] 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, it becomes possible to pose the figure with both shoulders tucked forward and both arms facing forward, as if both arms are stretched out and folded in front of the chest. For example, it becomes possible to recreate a cool pose with a gun held in front.

[0033] Furthermore, by locating the movable axis of the left chest part 24 and the right chest part 26 (left swing axis 226, right swing axis 227) halfway between 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 in which the central chest part 22, left chest part 24, and right chest part 26 appear to be connected as a chest.

[0034] Furthermore, the fact that the left swing axis 226 and the right swing axis 227 are located close to the back side with respect to the front-to-rear center line L2 of the chest 20 (see FIG. 4) increases the rotation radius of the ends of the left chest part 24 and the right chest part 26 near the central chest part 22 when the shoulders are swung forward, thereby making the tapered surface for avoiding interference with the central chest part 22 smaller, and contributing 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.

[0035] Second Embodiment Next, a second embodiment to which the present invention is applied will be described. In the following, differences from the first embodiment will be mainly described, and the same components as those in the first embodiment will be given the same reference numerals and overlapping descriptions will be omitted as appropriate.

[0036] FIG. 9 is a front view of the upper body showing a configuration example of a doll toy 2B in this 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.

[0037] 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 generally box-shaped body that opens on the 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 generally bowl-shaped or 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, forming an integrated and connected appearance as the chest 20.

[0038] In this embodiment, the connection between the central chest part 22B and the left and right chest parts 24B and 26B is realized by a ball joint 27. Also, the connection between the upper arm 40 and the left and right chest parts 24B and 26B is realized by a 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.

[0039] Naturally, the doll toy 2B in this embodiment can also be posed with both shoulders hunched forward in the same manner as in the first embodiment, and the same effect as in the first embodiment can be obtained. In other words, if we assume that the chest 20B is formed in a roughly box-like shape (assuming that the central chest part 22B, left chest part 24B, and right chest part 26B are an integrated structure that is not divided), then as shown in FIG. 12, it is not possible to hunch both shoulders forward, and therefore even if both arms are pointed forward (to the bottom of FIG. 12), the only posture that can be achieved is the so-called "stand together" posture.

[0040] However, as shown in Fig. 13, by dividing the chest 20B into the central chest part 22B, the left chest part 24B, and the right chest part 26B, it becomes possible to pose the figure with both arms outstretched and clasped in front of the chest by tucking both shoulders forward and pointing both arms forward. For example, it becomes possible to recreate a cool pose, such as holding a sword in front of the chest.

[0041] In this embodiment, the central chest part 22B is connected to the left chest part 24B and right chest part 26B by ball joints 27, so the shoulders can be tilted not only forward, but also diagonally downward and forward, upward and backward, overhead, upward and downward rear. The outer surfaces of the central chest part 22, the left chest part 24, and the right chest part 26 form the external appearance of an integrated chest 20.

[0042] Third Embodiment Next, a third embodiment to which the present invention is applied will be described. In the following, differences from the first and second embodiments will be mainly described, and the same components as those in the first and second embodiments will be given the same reference numerals and overlapping descriptions will be omitted as appropriate.

[0043] FIG. 14 is a front view showing a configuration example of a doll toy 2C in this embodiment. The doll toy 2C comprises, from the top, a head 10, a chest 20, an abdomen 30, and a waist 60, and adjacent parts among these are connected to each other by ball joints so that the relative angles between them can be changed.

[0044] The waist section 60 includes a waist base section 70 and a plurality of exterior sections 80 that cover the sides of the waist base section 70 .

[0045] The exterior part 80 comprises a large hanging part 81 that integrally covers the front of the waist part 60 from the navel to the groin, a left front hanging part 83 and a right front hanging part 84 that are connected to the upper end of the large hanging part 81 by a ball joint and cover the front of the left and right thigh joints, a left side hanging part 85 and a right side hanging part 86 that cover the left and right side surfaces of the waist part 60, and a buttock hanging 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 supported at their upper ends to the waist base part 70 so as to be swingable on a horizontal axis in the front-to-rear direction, and their lower ends are connected so as to be swingable up and down.

[0046] 15 is a perspective exploded view showing an example of the connection configuration between the waist base 70, the thigh portion 44, and the upper hanging portion 81. For ease of understanding, some parts are shown in perspective, and the connection structure between the waist base 70 and the other hanging portions (left side hanging portion 85, right side hanging portion 86, buttocks hanging portion 87) is not shown.

[0047] The waist base 70 is substantially a box-like body that is long in the front-to-back and up-down directions, and has a ball stud 71 at its upper end for connecting to the abdomen 30 via a ball joint. A large hanging 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 large hanging link 72 is connected to the waist base 70 by a link movable shaft 73 so as to be able to swing up and down. The front joint of the large hanging link 72 is connected to a large hanging movable shaft 74 at a bearing part 82 provided in the upper and lower middle part of the back surface of the large hanging part 81, and supports the large hanging part 81 so as to be able to swing up and down.

[0048] Connected to the left and right sides of the waist base 70 are thigh links 76 each having a ball stud 75 for connecting to the thighs 44 via a ball joint. The front joint of the thigh link 76 is connected to the link movable shaft 73. The rear joint of the thigh link 76 fits into an arc-shaped guide groove 77 provided in the waist base 70. In other words, the thigh link 76 is designed so that the rear joint can swing up and down around the link movable shaft 73 along the guide grooves 77 on the left and right sides of the waist base 70.

[0049] When viewed from the front, the movable axis (ball stud 75) for changing the angle of the thigh section 44 (second part) relative to the abdomen 30 (first part) is configured to be provided lower than the movable axis (large hanging movable axis 74) for changing the orientation of the large hanging section 81 (third part). When viewed from above, the movable axis (ball stud 75) for changing the angle of the thigh section 44 is located behind the movable axis (large hanging movable axis 74) for changing the orientation of the large hanging section 81, and is provided in a front-to-back position closer to the center of the trunk (ball stud 71).

[0050] Next, with reference to Figures 16 to 19, possible positional relationships of parts around the waist 60 when the doll toy 2C is changed from an upright posture to a kneeling and bending forward posture will be described. In these figures, some parts are shown in perspective to facilitate understanding of the relative positional relationships, and some parts are not shown.

[0051] FIG. 16 is a simplified cross-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 portion 31 inside that connects to the ball stud 71 in the internal space, and an opening 32 into which the upper end of the large hanging portion 81 can be inserted at the lower front end. However, in the upright position, the large hanging portion 81 is almost upright, and its upper end is located close to the front of the abdomen 30, covering and concealing the opening 32. Therefore, when the doll toy 2C is viewed from the front, the opening 32 is not noticeable, and the chest 20 → abdomen 30 → waist 60 form a large, continuous appearance. In the upright position, the exterior portion 80 also forms a large, continuous appearance around the sides of the waist 60 (see FIG. 14).

[0052] From this point, in order to make the doll toy 2C assume a kneeling pose, it is necessary to change the orientation of the thighs 44 (shown in perspective in Figs. 16 to 19) so that they face forward, and the parts around the waist 60 transition 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 axis of rotation, and the ball stud 75 is lowered to the front lower end of the waist base 70. At the same time, the thighs 44 are laid down on their sides so that the front side faces up.

[0053] To make the doll toy 2C bend forward, the orientation of the abdomen 30 is changed so as to reduce the angle it forms with respect to the waist 60 while changing the orientation of the thigh link 76 and the thigh 44, changing the angle of the upper hanging part 81. In other words, the abdomen 30 is tilted forward.

[0054] Specifically, as shown in Fig. 16, in the upright position of the large hanging link 72, the front joint is located above the link movable shaft 73 and the ball stud 75. To bend forward from this position, first, as shown in Figs. 17 and 18, the large hanging link 72 is rotated about the link movable shaft 73 so as to lower the front joint, and the swing shaft of the large hanging link 72 moves forward while lowering, and the swing shaft of the large hanging portion 81 moves away from the abdomen 30. This expands the interference prevention space Sp (see Fig. 18) between the abdomen 30 (first part) and the large hanging portion 81 (third part).

[0055] From there, as shown in Figures 18 and 19, the upper end of the large hanging portion 81 is tilted 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 bending the abdomen 30 forward significantly, it is possible to create an appearance that is connected without a large gap from the abdomen 30 to the lower back 60 when viewed from the front. A tapered surface T is provided at the upper end of the large hanging portion 81 (see Figures 15 and 16), which has the effect of avoiding contact with the opening 32 of the abdomen 30 when changing the orientation of the large hanging portion 81.

[0056] Furthermore, this movement of the swinging position and change of direction of the larger hanging portion 81 also has the effect of creating a large, continuous appearance around the sides of the waist portion 60. 20 and 21 are simplified perspective views showing parts around the waist portion 60. FIG. Assuming that the swing position of the large hanging portion 81 (the front joint of the large hanging link 72; the large hanging movable axis 74 (see FIG. 15)) cannot be changed as in this embodiment, when the right thigh 44 is swung forward to make the doll toy 2C kneel down, as shown in FIG. 20, the right front hanging portion 84 is also swung up, but the large hanging portion 81 remains in an upright position, and a large discontinuity 9 in appearance is generated in the right groin. However, in this embodiment, as shown in FIG. 21, the large hanging portion 81 can be swung up forward while being laid down, so that a large seamless appearance can be formed in the lateral direction from the right front hanging portion 84 to the large hanging portion 81 to the left front hanging portion 83, and the design of the appearance can be improved.

[0057] According to the joint structure of the doll toy according to the embodiment described above, when the second part (for example, the upper arm 40 in FIG. 8 and the thigh 44 in FIG. 14) is moved so as to reduce the angle formed with the first part (for example, the chest 20 in FIG. 8 and the abdomen 30 in FIG. 14), the third part (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, the left front hanging part 83, and the right front hanging part 84 in FIGS. 14 and 21) can be moved in accordance with the movement of the second part. For example, when the doll toy is posed with its arms thrust out as if clasping both hands in front of its chest with the first part as the central chest, the second part as the arms, and the third part as the left and right chests, the left and right chests (the left and right parts of the chest) can be moved in accordance with the movement of the arms. In other words, the trunk (the entire chest in this example), which was previously constructed as a single box, is divided into the first and third parts, and the third part can be moved in accordance with the movement of the second part, thereby increasing the degree of freedom of movement of the joints. In addition, by having the third part mediate between the first and second parts, it is possible to form a connected appearance without a sense of discontinuity (a large visible gap) connecting the first, third, and second parts, which makes it possible to suppress a decrease in the appeal of the exterior design.

[0058] Furthermore, in this embodiment, the first part and the third part are configured such that, when the third part is rotated in a direction that reduces the angle they form, one part overlaps with the other part on the outside, thereby making it possible to form a connected appearance with little apparent discontinuity while avoiding interference between the first part and the third part.

[0059] In this embodiment, the third part has a tapered surface at the end closer to the first part to avoid contact with the first part during rotation, so that interference between the first and third parts can be reliably avoided even if the gap between the first and third parts is small. The tapered surface also appropriately buffers the difference in angle between the outer surface of the first part and the outer surface of the third part, making the transition between the appearances of the two parts appear smoother even if the first and third parts have linear designs.

[0060] In addition, in this embodiment, the movable axis for changing the angle of the second part (for example, the ball stud 243 for the left arm and the left shoulder axis 244 in FIG. 3) is configured to be provided at a position farther from the center of the trunk than the movable axis for changing the direction of the third part (for example, the left swing axis 226 in FIG. 3). Therefore, even if the second part is configured to be disposed to the side of the first part, the third part that forms an angle with the first part at an angle gentler than the angle that the second part forms with the first part can be disposed between the first part and the second part. Therefore, when the pose of the doll toy as a whole is seen, 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 more beautiful.

[0061] In addition, 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. In this manner, by dividing the chest into at least three parts, one in the center and one on the left and right, it becomes possible to slouch the shoulders forward, and the doll toy can recreate cool poses such as holding a sword or gun with both arms stretched out in front of the chest and clasped together.

[0062] Furthermore, in this embodiment, since the third part has a support portion that supports the second part, the third part can also serve as the support structure for the second part.

[0063] In addition, in this embodiment, the movable shaft for rotating the second part (for example, the ball stud 75 in Figs. 14 and 15) is configured to be provided below the movable shaft for rotating the third part (for example, the large vertical movable shaft 74 in Fig. 15) in a front view. Therefore, even if the second part is configured to be disposed below the first part, the third part, which forms an angle with the first part at an angle gentler than the angle that the second part forms with the first part, can be disposed between the first and second parts. Therefore, when the pose of the doll toy as a whole is seen, 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 more beautiful.

[0064] Furthermore, in this embodiment, the third part has a portion above and below a movable axis (e.g., large vertical movable axis 74 in FIG. 15) for rotating the third part, and is configured so that when the third part is rotated in a direction that reduces the angle, one of the upper and lower portions of the third part partially overlaps with the outside of the first part, and the other partially overlaps with the inside of the first part (e.g., FIGS. 16 to 19).Therefore, it is possible to form an external appearance that has less of a sense of discontinuity and a sense of continuity while avoiding interference between the first part and the third part.

[0065] In this embodiment, the first part is a part for the abdomen (for example, abdomen 30 in FIG. 14), the second part is a part for the legs (for example, thighs 44 in FIG. 14), and the third part is a part for the appearance of the waist (for example, upper abdomen 81 in FIG. 14), so that the position of the third part for the appearance of the waist can be changed according to the change in the position of the second part, the legs. Therefore, for example, according to a kneeling pose, the appearance parts around the waist can be changed to an appropriate position to realize a natural and good-looking appearance.

[0066] In this embodiment, the third part is configured to swing relative to the first part, and further includes a link part (e.g., large hanging link 72 in FIG. 15) whose one end supports the swing axis of the third part and whose other end is supported by the link part, and the swing axis of the third part is configured to be vertically adjustable by swinging the link part up and down around the other end as the axis center, so that the position of the swing axis of the third part (e.g., large hanging part 81 in FIG. 14) can be changed. This expands the changeable postures and positions of the third part, and contributes to realizing various poses of the doll toy.

[0067] Furthermore, in this embodiment, when the second part is rotated so as to reduce the angle, the link part is swung downward to expand the interference prevention space between the first part and the third part. As the link part swung downward with the rotation of the second part, the whole third part is moved in a direction away from the first part, expanding the interference prevention space. The expansion of the interference prevention space increases the room for changing the position of the third part so that it does not interfere with the first part, and makes it easier to change the orientation of the third part in a direction that reduces the angle it forms with the first part. As a result, when viewed as a whole doll toy, the angle the third part forms with the first part can be made smaller.
