Description

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

  There is a known doll toy that is assembled by assembling parts for each part and can be played in various poses. 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 a movable region is widened by deforming or bending.

Registered Utility Model Publication No. 3185443 Publication

  As one of the design themes for doll toys, humanoid robot design is known. In doll toys designed as humanoid robots, the main trunk, such as the chest, abdomen, and waist, often has a linear and mechanical design covered with armor. Conventionally, those trunk parts are one box-shaped part. Has been designed as. Therefore, it is easy for the movable parts provided on the trunk to move freely.

  Specifically, for example, in TV anime and manga for heroes, poses with swords and guns appearing with arms extended in front of the chest often appear, so as a user, I definitely want to reproduce it with doll toys. I just hope. However, if the chest is designed as one box-shaped body 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 make a pose in which your arms are extended to the front, only the arms bend forward with the shoulder position unchanged, which is why it is a so-called "front look" pose. In some cases, you could bend your elbow joints with your arms forward, so that you could put your hands together, but then you would end up with an awkward “stance”, and you would be far from your original “position” to extend your arms. It was In any case, the wish was not fulfilled.

  It is conceivable that the above-mentioned “ready” may be realized by using the joint mechanism using the soft material disclosed in Patent Document 1. However, if you can see the wrinkles and flexure of the soft material, the "attack" itself can be made, but the original appeal of the external design is lost. Further, since the flexed soft material tries to restore, the above-mentioned "stance" cannot be maintained.

The above-mentioned problem of “preparation” is an example, and it has been a problem that occurs in other joints when the joint is bent largely (or deeply).
An object of the present invention is to provide a technique capable of increasing the degree of freedom of movement of a joint while suppressing the attractiveness of the external design.

The joint structure of the doll body according to the present invention is the joint structure of the doll body, and comprises the first part (for example, the chest 20 of FIG. 8 and the abdomen 30 of FIG. 14) forming the trunk and the four limbs, A second part that is rotatable with respect to the first part (for example, the upper arm part 40 in FIG. 8 and the thigh part 44 in FIG. 14) and a part of the trunk or an appearance of the trunk, and constitutes the first part. And a third part that is rotatable with respect to the second part, when the third part is rotated so as to reduce the angle formed by the second part and the first part, the third part is formed in accordance with the rotation of the second part. A third part configured to be rotatable in a direction that reduces the angle (for example, the left chest part 24 and the right chest part 26 of the chest 20 of FIG. 8, the drooping part 81 of FIG. 14 and FIG. A portion 83 and a right front hanging portion 84). Further, the joint structure of the doll body according to the present invention is located at a central part of the chest and on either the left or right side of the chest, and constitutes a part of the chest or the appearance of the chest, and with respect to the central part of the chest. A front side of the chest is provided with rotatable side parts of the chest and arm parts rotatable with respect to the side parts of the chest, and when the side parts of the chest are rotated with respect to the center part of the chest. The width in the left-right direction becomes narrower. Further, the joint structure of the doll body according to the present invention is a joint structure of the doll body, which is located on the chest central part and on either the left or right side of the chest, and shows a part of the chest or the appearance of the chest. A center of rotation of the chest side part with respect to the chest, which comprises a side part of the chest rotatable with respect to the center part of the chest and an arm part rotatable with respect to the side part of the chest. Is located closer to the back of the chest with respect to the front-back centerline of the chest, and when the side parts of the chest are rotated with respect to the center part of the chest, the width of the front of the chest in the left-right direction becomes narrower. ..

Further, according to the present invention, the first part and the third part are arranged such that, when the third part is rotated in a direction in which the angle formed by the first part and the third part is rotated, one part of the first part and the third part partially overlap with the outside and the other part overlaps with the inside. It may be configured. Further, in the joint structure of the doll body according to the present invention, one of the chest central part and the chest lateral part may partially overlap the outside and the other inside when the chest lateral part is rotated. You may comprise.

Further, in the present invention, the third part may have a tapered surface at an end portion near the first part for avoiding contact with the first part during rotation. Further, in the joint structure of the doll body according to the present invention, the side parts of the chest may have a tapered surface at an end near the center part of the chest for avoiding contact with the center part of the chest during rotation. You can

  Further, according to the present invention, in a top view, 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) serves to change the direction of the third part. The movable shaft (for example, the left swing shaft 226 in FIG. 3) may be provided at a position farther from the center of the trunk than the movable shaft.

  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 positioned on the left and right sides of the chest.

[First Embodiment]
FIG. 1 is a perspective external view of the upper half of the 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, the head 10, the chest 20, the abdomen 30, the upper arm 40, and the back sac 50 of the doll toy 2 are selectively illustrated, but not shown in the figures. Parts (for example, lower arm, waist, leg, etc.) are also provided as appropriate. The user can arbitrarily change the relative orientation and relative posture of each of these parts to 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 that constitutes the trunk, and forms the left and right center parts of the chest 20 in the present embodiment. The left chest part 24 and the right chest part 26 are third parts that form part of the trunk or the appearance of the trunk. In this embodiment, the right half corresponding to the right shoulder and the right lung is formed, and the left half corresponding to the left shoulder and the left lung is 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 continuous appearance as the chest 20.

FIG. 2 is a front view of the doll toy 2 according to 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 according to 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 this embodiment.

As shown in FIG. 3, the central chest part 22 of the present embodiment is bilaterally symmetrical 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 and right sides and a lower side, and forms the upper surface, the central front surface, and the central rear surface of the chest 20. Further, a joint portion 223 for connecting the ball joint 12 that connects the head 10 is provided on the upper portion.
The lower part 222 includes a bottom surface 224 of the chest 20 that is connected to the abdomen 30, a joint connecting column 225 that connects to the joint 223, and a left swing shaft 226 that connects the left chest part 24 rotatably left and right. And a right swing shaft 227 that rotatably supports the right chest part 26 so as to be rotatable left and right.

The left chest part 24 and the right chest part 26 are symmetrical to each other in the present 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 the lower side, and forms a part of the front, side, back, and upper surfaces of the left chest half, and a left swing shaft 226. And a left bearing 242 for vertically inserting the upper arm 40 and a left arm ball stud 243 for connecting the left upper arm 40 (second part) with a ball joint. The ball stud 243 for the left arm forms an upper front and rear center upper surface of the left chest half 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 make a pose of raising the left shoulder by swinging the ball stud 243 for the left arm in the vertical direction with the left shoulder shaft 244.

  In the present embodiment, the movable shaft (the left arm ball stud 243, the left shoulder shaft 244) for changing the angle of the upper arm 40 (second part) changes the orientation of the left chest part 24 (third part). It is provided at a position more distant from the center line L1 of the trunk than the movable shaft (left swing shaft 226) for moving (see FIG. 3). Further, when viewed from above, the left swing shaft 226 is erected at a position close to the back of the chest with respect to the front-rear centerline 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 part 226 is inserted into the left bearing 242 so that the left chest part 24 is assembled to the lower part 222 from above. Has been. Then, in the same manner, the right-side 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. Then, the upper arm 40 is 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. However, it is in a state of being inserted from the right opening of the central chest part 22 to the inside thereof.

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

  At this time, the front part of the left chest part 24 and the end part close to 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 part A gap is not easily formed between the chest part 22 and the chest part 22. As a result, the continuous appearance of the chest 20 is preferably maintained. The same applies to the right chest part 26 and the central chest part 22.

  Further, a tapered surface T is provided at each of the end portion of the left chest part 24 closer to the center chest part 22 and the end portion of the right chest part 26 closer to the center of the chest. When changing the orientation, it avoids contact with the central chest part 22 and creates a smooth outer surface connection. The shape of the tapered surface T is not limited to a linear gradient surface, and may be formed of a curved surface formed of a rotating body around the swing shafts 226 and 227, and contact with the central chest part 22 is avoided. It may be formed by a free-form surface whose volume is reduced.

FIG. 6 is a cross-sectional view taken along the line AA of FIG. 2, and is a cross-sectional view when both shoulders are turned forward. As shown in FIG. 6, the doll toy 2 according to the present embodiment can be placed in a pose in which both shoulders are swollen forward.
That is, the direction of the left chest part 24 is changed around the left swing shaft 226 so that the angle formed by the front surface of the central chest part 22 and the front surface of the left chest part 24 that form the trunk is reduced. You can As a result, the ball stud 243 for the left arm is rotated forward and is deformed so that the width of the front of the chest 20 in the left-right direction is narrowed, and a pose as if the shoulder is swung forward is completed. At this time, the end of the left chest part 24 close to the front center chest part 22 is inserted further inside the center chest part 22 as the direction is changed. As a result, the volume of the front of the chest formed by the left chest part 24 and the central chest part 22 becomes small and the movement of the upper arm 40 is not obstructed when it is attempted to make a pose in which the shoulder is swollen forward. By doing so, it is possible to appropriately maintain the outer appearance of the chest 20 while expanding the movable range of the upper arm 40. The same applies to the right chest part 26 and the central chest part 22.

Since the doll toy 2 in the present embodiment can be made to pose in such a manner that both shoulders are swollen forward, the doll toy 2 in this embodiment can be made in more diverse and natural poses.
Specifically, for example, as shown in FIG. 7, the chest 20 is formed into one substantially box shape like a conventional doll toy (central chest part 22, left chest part 24, right chest part). In the case of not having a divided structure such as 26), since both shoulders cannot be swung forward, even if both arms are directed to the front (the lower side of FIG. 7), so-called “become front” I can only do posture.

  However, as shown in FIG. 8, if the chest 20 is divided into the central chest part 22, the left chest part 24, and the right chest part 26 as in the present embodiment, both shoulders should be swung forward. With both arms facing forward, it is possible to pose with the arms folded in front of your chest. For example, you will be able to reproduce a cool pose with a gun in front.

  Moreover, the movable shafts (the left swing shaft 226 and the right swing shaft 227) of the left chest part 24 and the right chest part 26 are set to the ball stud 243 which is the movable shaft of the left and right arms and the center of the trunk (center line L1. (See FIG. 3), the central chest part 22, the left chest part 24, and the right chest part 26 can be realized as a chest in a top view.

  Further, the left swing shaft 226 and the right swing shaft 227 are provided at positions close to the back surface with respect to the longitudinal centerline L2 of the chest 20 (see FIG. 4) when swinging the shoulder forward. By increasing the turning radius of the ends of the left chest part 24 and the right chest part 26 near the center chest part 22, the taper surface for avoiding interference with the center chest part 22 is reduced, This contributes to the realization of a top view with the impression that the central chest part 22, the left chest part 24, and the right chest part 26 are connected as a chest.

[Second Embodiment]
Next, a second embodiment to which the present invention is applied will be described. Note that, hereinafter, the difference from the first embodiment will be mainly described, the same components as those in the first embodiment will be denoted by the same reference numerals, and overlapping description will be appropriately omitted.

FIG. 9 is a front view of the upper half of the body showing a configuration example of the doll toy 2B in the present embodiment.
FIG. 10 is a partial 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 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, and the left end of the right chest part 26B covers the outside of the right opening of the central chest part 22B. It forms an integrated and continuous appearance as.

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

As a matter of course, the doll toy 2B in the present embodiment can also achieve the same effect as that of the first embodiment by allowing the shoulders to squeeze forward as in the first embodiment.
That is, if it is assumed 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 have an integrated configuration that is not a divided configuration. ), As shown in FIG. 12, since both shoulders cannot be swung forward, even if both arms are directed to the front (lower side in FIG. 12), only a so-called “frontal 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 can be swung forward and both arms forward. If you point it, you will be able to pose with your arms extended as if they stick out in front of your chest. For example, you will be able to reproduce a cool pose such as holding a sword in front of your chest.

  In addition, in the present embodiment, since the central chest part 22B is connected to the left chest part 24B and the right chest part 26B by the ball joint 27, not only the shoulder but also the front diagonal downward direction. Also, it can be slanted forward diagonally upward, overhead, backward diagonally upward, diagonally backward 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 continuous appearance as the chest 20.

[Third Embodiment]
Next, a third embodiment to which the present invention is applied will be described. Note that, hereinafter, the difference from the first and second embodiments will be mainly described, the same components as those in the first and second embodiments will be denoted by the same reference numerals, and redundant description will be appropriately omitted. To do.

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

  The waist 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 hanging part 81 that integrally covers the front of the waist 60 from the navel to the crotch, and a left front hanging part that is connected to the upper end of the large hanging part 81 by a ball joint and covers the front of the left and right femoral joints. A portion 83 and a right front hanging portion 84, a left side hanging portion 85 and a right side hanging portion 86 that cover the left and right side surfaces of the waist portion 60, and a tail hanging portion 87 (see FIG. 17) that covers the rear portion of the waist portion 60 are provided. The left side hanging portion 85 and the right side hanging portion 86 are swingably supported on the waist base portion 70 by a horizontal axis in the front-rear direction at their upper ends, and the lower ends thereof are swingably connected vertically.

  FIG. 15 is a perspective exploded view showing a connection configuration example of the waist base portion 70, the thigh portion 44, and the drooping portion 81. In addition, for facilitating understanding, a part thereof is shown in perspective, and a connecting structure between the waist base 70 and other hanging parts (left hanging part 85, right hanging part 86, buttocks 87) is omitted in the drawing. There is.

The waist base 70 is a substantially box-shaped body 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 the abdomen 30 with a ball joint.
Further, a large drooping link 72 is vertically swingably connected to the upper front part of the waist base 70. The rear joint of the dangling 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 large drooping link 72 is connected by a large drooping movable shaft 74 by bearings 82 provided at the upper and lower intermediate portions on the back surface of the large drooping part 81, so that the large drooping part 81 can be swung vertically. I support you.

To the left and right side surfaces of the waist base portion 70, thigh links 76 each having a ball stud 75 for connecting to the thigh portion 44 by a ball joint are connected.
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 in an arcuate guide groove 77 provided in the waist base 70. That is, in the thigh link 76, 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.

  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) has a large droop 81 (third part). It is provided below the movable shaft (large drooping movable shaft 74) for changing the direction. Further, when viewed from above, the movable shaft (ball stud 75) for changing the angle of the thigh 44 is rearward of the movable shaft (large drooping movable shaft 74) for changing the direction of the drooping part 81. It is provided at the front and rear positions closer to the center of the trunk (ball stud 71).

  Next, with reference to FIGS. 16 to 19, a description will be given of a positional relationship that 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. In these figures, in order to facilitate understanding of the relative positional relationship, some parts are shown in perspective and some parts are not shown.

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 the upright posture.
The abdominal part 30 has a socket part 31 connected to the ball stud 71 in the internal space, and an opening 32 into which the upper end of the drooping part 81 can be inserted at the lower end of the front side. However, the drooping portion 81 in the upright posture is almost upright, and its upper end is 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, and the chest 20 → the abdomen 30 → the waist 60 forms a large, continuous appearance. In the upright posture, the outer circumference of the waist 60 also forms a continuous appearance with a large gap (see FIG. 14).

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

  In order to bend the doll toy 2C forward, the angle formed between the abdomen 30 and the waist 60 while changing the angle of the dangling part 81 in parallel with the change in the orientations of the thigh link 76 and the thigh 44. Turn to reduce. That is, the abdomen 30 is tilted forward.

  Specifically, as shown in FIG. 16, in the drooping 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 drooping link 72 is rotated about the link movable shaft 73 so as to lower the front joint. Then, the swing shaft of the large droop link 72 moves downward and moves forward, and the swing shaft of the large droop portion 81 is separated from the abdomen 30. As a result, the interference prevention space Sp (see FIG. 18) between the abdomen 30 (first part) and the drooping part 81 (third part) is expanded.

  From there, as shown in FIGS. 18 to 19, the upper end of the drooping 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 drooping part 81 is inserted into the internal space of the abdomen 30. As a result, it is possible to form a large, continuous appearance from the abdomen 30 to the waist 60 when viewed from the front, while bending the abdomen 30 largely forward. A taper surface T is provided on the upper end of the drooping portion 81 (see FIGS. 15 and 16) to avoid contact with the opening 32 of the abdomen 30 when changing the direction of the drooping portion 81. Produce an effect.

The movement of the swinging position and the change of the direction of the drooping portion 81 have an effect of forming a large continuous continuous outer appearance of the waist 60 as well.
20 and 21 are simplified perspective views showing the parts around the waist 60 extracted.
Assuming that the swing position of the large drooping portion 81 (the front joint of the large drooping link 72; the large drooping movable shaft 74 (see FIG. 15)) cannot be changed as in this embodiment, as shown in FIG. Further, when the right thigh 44 is swung forward to make the doll toy 2C pose with a standing knee, the right front hanging part 84 is also swung up, but the large hanging part 81 is in the upright posture. It remains in the position, and a large discontinuity 9 appears in the right groin. However, in the present embodiment, as shown in FIG. 21, the large hanging part 81 can be laid down while being swung forward, so that a large break is formed around the right front hanging part 84 → the large hanging part 81 → the left front hanging part 83. It is possible to form a non-existent appearance and improve the appearance design.

  According to the joint structure of the doll toy according to the embodiment described above, the second part (for example, the upper arm 40 of FIG. 8 and the thigh 44 of FIG. 14) is connected to the first part (for example, the chest of FIG. 8). 20, the abdomen 30 of FIG. 14) and the third part (eg, the left chest part 24 and the right chest part 26 of the chest 20 of FIG. 8) when moving to reduce the angle formed. The large hanging part 81, the left front hanging part 83, and the right front hanging part 84) can be moved according to the movement of the second part. For example, if the first part is the central chest, the second part is the arm, and the third part is the left and right chest, and you try to pose the doll toy with your arms in front of your chest, In addition, the left and right chest (the left and right sides of the chest) can be moved. In other words, the trunk (in this example, the entire chest), which was conventionally configured as one box, is divided into the first part and the third part, and the third part is also moved 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 the space between the first part and the second part, which leads to a sense of discontinuity (a large visible break) that leads to the first part, the third part, and the second part. Since it is possible to form a continuous appearance that does not exist, it is possible to suppress the attractiveness of the appearance design.

  Further, in the present embodiment, one of the first part and the third part partially overlaps with the outside and the other part overlaps with the inside when the third part rotates in a direction in which the angle formed is reduced. With such a configuration, it is possible to form a continuous appearance with less apparent discontinuity while avoiding interference between the first part and the third part.

  In addition, 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 during rotation. Even if the gap between the part and the third part is made small, it is possible to reliably avoid the interference between both parts. 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 the appearance of both parts is continuous even if the first and third parts have a linear design. Can be made to look smoother.

  In the present embodiment, the movable shaft (for example, the left arm ball stud 243 and the left shoulder shaft 244 in FIG. 3) for changing the angle of the second part changes the direction of the third part in a top view. The second part is arranged laterally of the first part because it is 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). Even with the configuration, the third part that forms an angle with the first part at a gentler angle than the angle that the second part forms with 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 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 to each other, so that the angle change of the outer surface becomes smoother, and the doll toy 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, and hold both swords and guns with both arms extended in front of the chest. You will be able to reproduce the cool pose with doll toys.

  In addition, in the present embodiment, since the third part has the support part that supports the second part, the support structure of the second part can also serve as the third part.

  Further, in the present embodiment, when viewed from the front, 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 the shaft is provided below the shaft (for example, the large drooping 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, which forms an angle with the first part at a gentler angle than the angle with respect to the part, can be arranged between the first part and the second part. Therefore, when the pose of the doll toy as a whole is seen, the change in the angle of the outer surface connecting 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 the doll toy looks beautiful.

  Further, in the present embodiment, the third part has a portion above and below a movable shaft (for example, the large hanging movable shaft 74 of FIG. 15) for rotating the third part. , One of the upper part and the lower part of the third part is outside the first part and the other is the other part when the third part is rotated in a direction to reduce the angle formed by the third part. Since it is configured so as to partially overlap the inside of the first part (for example, FIGS. 16 to 19), it is possible to avoid the interference between the first part and the third part, and visually, there is little discontinuity and a sense of continuity. It can form a solid 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 leg (for example, the thigh 44 in FIG. 14). The third part is a part for external appearance of the waist (for example, the drooping part 81 in FIG. 14), whereby the third part can be changed according to the position change of the leg part which is the second part. It is possible to change the position of the waist appearance parts. Therefore, for example, in response to a standing knee pose, the appearance parts around the waist can be changed to appropriate positions, and a natural and attractive appearance can be realized.

  Further, in the present embodiment, 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 which is pivotally supported. Further includes a link part (for example, a large hanging link 72 in FIG. 15), and the link part is vertically moved about the other end so that the swing shaft of the third part is vertically moved. Since it is configured to be adjustable, the position of the swing shaft of the third part (for example, the drooping portion 81 in FIG. 14) can be changed. Therefore, the changeable posture and position of the third part can be expanded to contribute to the realization of various poses of the doll toy.

  In addition, 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 enlarged, the link part swings downward with the rotation of the second part, so that the entire third part moves 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 orientation of the third part in the direction of reducing the angle formed with respect to the first part. Become. As a result, when viewed as a doll toy as a whole, the angle formed by the third part with respect to the first part can be made smaller.
