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

Background

There is known a human-shaped toy which is configured by assembling parts of different parts and can be played in various postures. For example, patent document 1 discloses a joint mechanism of a human-shaped toy in which a connecting portion such as a shoulder is formed of a soft material and a moving region is enlarged by deformation or bending.

[ problems to be solved by the invention ]

And, as one of design subjects of the humanoid toy, a design of a humanoid robot is known. In a human-shaped toy designed as a human robot, a main trunk such as a chest, an abdomen, and a waist is often designed to be linear and mechanical in which the trunk is covered with an armor, and these trunk parts have been designed as one box-shaped part in the past. Therefore, the movement of the movable portion provided on the trunk is likely to be lost.

Specifically, for example, in television animation or comic of hero characters, a posture in which both hands are stretched out and overlapped in front of the chest to hold a sword or a gun often occurs, and thus it is certainly desired as a user to reproduce the scene with a human figure toy. However, if the chest is designed as a box-like body as in the past, the position of the shoulder portion of the upper arm connected to the shoulder joint is substantially fixed. Therefore, even when the user tries to assume a posture in which the arm is extended forward to a large extent, the shoulder portion is bent forward only by the arm while maintaining its position, and hence the user assumes a so-called "looking forward". In addition, although the arms may be bent forward to fold the elbow joints, the arms may be placed in an unattractive "posture" that is far from the original "posture" of the arm. In short, the expectation cannot be satisfied.

It is also considered that the "posture" may be achieved if the joint mechanism using a soft material disclosed in patent document 1 is used. However, if wrinkles or bends in the soft material can be seen, the "posture" itself can be realized, but the original attractiveness of the design is impaired. In addition, the "posture" cannot be maintained because the soft material that is bent is intended to be restored.

The "posture" is an example, and is a problem that occurs when the joint is bent largely (or deeply) in another joint.

The purpose of the present invention is to provide a technique that can improve the degree of freedom in movement of a joint section while suppressing a reduction in the attractiveness of the appearance design.

[ means for solving problems ]

The joint structure of a human body of the present invention comprises: part 1 (e.g., chest 20 of fig. 8, abdomen 30 of fig. 14) forming the torso; a 2 nd component (for example, an upper arm portion 40 in fig. 8 and a thigh portion 44 in fig. 14) constituting an extremity and rotatable with respect to the 1 st component; and 3 rd parts (for example, a left chest part 24 and a right chest part 26 of the chest 20 in fig. 8, and a large hanging part 81, a left front hanging part 83, and a right front hanging part 84 in fig. 14 and 21) which constitute a part of the trunk or an external appearance of the trunk, are rotatable with respect to the 1 st part, and are configured to be rotatable in a direction in which an angle formed by the 2 nd part and the 1 st part is reduced in accordance with the rotation of the 2 nd part when the rotation is performed in such a manner that the angle formed by the 2 nd part and the 1 st part is reduced.

In the present invention, the 1 st part and the 3 rd part may be partially overlapped one on the other outward and inward when the 3 rd part is rotated in a direction to reduce the angle.

In the present invention, the 3 rd part may have a tapered surface at an end portion close to the 1 st part to prevent the contact with the 1 st part during the rotation.

In addition, in the present invention, in a plan view, the movable shaft (for example, a left arm ball stud 243 and a left shoulder shaft 244 in fig. 3) for changing the angle of the 2 nd component may be provided at a position distant from the center of the trunk than the movable shaft (for example, a left swing shaft 226 in fig. 3) for changing the orientation of the 3 rd component.

In the present invention, the 1 st part may be a part for a chest center, the 2 nd part may be a part for an arm, and the 3 rd part may be a part located on the left and right sides of the chest.

In the present invention, the 3 rd component may include a support portion for supporting the 2 nd component.

In the present invention, the movable shaft (for example, a ball stud 75 in fig. 14 and 15) for rotating the 2 nd component may be provided below the movable shaft (for example, a large vertical movable shaft 74 in fig. 15) for rotating the 3 rd component in a front view.

In the present invention, the 3 rd component may have an upper portion and a lower portion with respect to a movable shaft (for example, a large vertical movable shaft 74 in fig. 15) for rotating the 3 rd component, and when the 3 rd component is rotated in a direction to reduce the angle, one of the upper portion and the lower portion of the 3 rd component partially overlaps with the other in the direction to reduce the angle (for example, fig. 16 to 19).

In the present invention, the 1 st part may be an abdomen part (for example, an abdomen part 30 in fig. 14), the 2 nd part may be a leg part (for example, a thigh part 44 in fig. 14), and the 3 rd part may be a waist part appearance part (for example, a hanging part 81 in fig. 14).

In addition, the present invention may be configured such that the 3 rd component is configured to swing with respect to the 1 st component, and further includes a link component (for example, a large vertical link 72 in fig. 15) having one end supporting a swing shaft of the 3 rd component and the other end supported by a shaft, and the swing shaft of the 3 rd component is vertically adjustable by swinging the link component up and down with the other end as a shaft center.

In the present invention, when the 2 nd component is rotated so as to reduce the angle, the interference preventing space between the 1 st component and the 3 rd component can be enlarged by swinging the link component downward.

Detailed Description

[ embodiment 1]

The human-shaped toy 2 is a toy constructed by assembling parts at different positions. In the illustrated example, the head 10, the chest 20, the abdomen 30, the upper arm 40, and the bladder 50 of the human-shaped toy 2 are selectively illustrated, but components (for example, the lower arm, the waist, and the legs) at positions not illustrated may be appropriately provided. The user can freely change the relative orientation or relative posture of these components, and can enjoy the fun of variously changing the posture of the human-shaped toy 2.

The chest portion 20 of the present embodiment has a center chest part 22, a left chest part 24, and a right chest part 26.

Specifically, the center chest part 22 is the 1 st part constituting the trunk, and forms the left and right center portions of the chest 20 in the present embodiment. Left chest part 24 and right chest part 26 are the 3 rd part that forms part of the torso or the appearance of the torso. In the present embodiment, a right half corresponding to the right shoulder and the right lung and a left half corresponding to the left shoulder and the left lung are formed, respectively. The outer surface of the center chest part 22, the outer surface of the left chest part 24, and the outer surface of the right chest part 26 form an appearance in which the chest part 20 is integrally continuous.

Fig. 2 is a front view of the human-shaped toy 2 according to the present embodiment, and includes a partial sectional view obtained by cutting the front side of the left chest part 24.

Fig. 3 is a front exploded view of the human-shaped toy 2 according to the present embodiment, and includes a partial sectional view of the left chest part 24 cut on the front side.

Fig. 4 is a plan view of the human-shaped toy 2 of the present embodiment.

As shown in fig. 3, the center chest part 22 of the present embodiment has a left-right symmetrical shape, and includes an upper part 221 and a lower part 222.

The upper part 221 is a substantially box-shaped body that is open to the left, right, and lower sides, and forms the upper surface, the center front surface, and the center rear surface of the chest portion 20. Further, joint portion 223 for connecting ball joint 12 is provided at the upper portion, and ball joint 12 is connected to head 10.

The lower part 222 has: a bottom surface 224 of the chest part 20 connected to the abdomen part 30; a joint connection column portion 225 connected to the joint portion 223; a left swing shaft 226 which connects the left chest component 24 to be rotatable left and right; and a right swing shaft 227 for pivotally supporting the right chest part 26 to be rotatable in the right and left directions.

The left chest part 24 and the right chest part 26 are symmetrical with each other in the present embodiment. Hereinafter, the left chest part 24 will be representatively described.

The left chest part 24 is a box-shaped body that opens rightward and downward, and includes: a left exterior portion 241 forming a part of the front, side, back and upper surfaces of the left half of the chest; a left bearing 242 through which the left swing shaft 226 is inserted vertically; and a left-arm ball stud 243 for ball-joint coupling the left upper arm portion 40 (part 2). The left-arm ball stud 243 is pivotally supported so as to be able to swing up and down by a left shoulder shaft 244, and the left shoulder shaft 244 is provided so as to form the front-rear center upper surface of the left half of the chest portion and extend in the front-rear direction inside the left exterior portion 241. That is, the human-shaped toy 2 can be put in a posture of lifting the left shoulder by swinging the left arm ball stud 243 in the vertical direction by the left shoulder shaft 244.

In the present embodiment, the movable shafts (the left arm ball stud 243 and the left shoulder shaft 244) for changing the angle of the upper arm portion 40 (the 2 nd component) are provided at positions that are farther from the center line L1 of the trunk than the movable shaft (the left swing shaft 226) for changing the orientation of the left chest component 24 (the 3 rd component) (see fig. 3). The left swing shaft 226 is provided upright at a position close to the back of the chest 20 with respect to the front-rear center line L2 thereof in plan view (see fig. 4).

As shown in fig. 3, in the upper body of the human-shaped toy 2 of the present embodiment, the left chest part 24 is assembled from above with respect to the lower part 222 so that the left swing shaft 226 is inserted into the left bearing 242. Then, in the same manner, the right chest part 26 is assembled from above with respect to the lower part 222 with the right swing shaft 227 inserted to the right bearing. Further, an upper part 221 is assembled from above the left and

right chest parts

24 and 26. Then, the upper arm portion 40 is assembled to each of the left and

right chest parts

24 and 26, and the head 10 is assembled to the joint portion 223.

Therefore, as shown in fig. 4, the front end of the right end portion of the left chest part 24 is inserted from the left opening of the center chest part 22 to the inside thereof, and the front end of the left end portion of the right chest part 26 is inserted from the right opening of the center chest part 22 to the inside thereof.

Fig. 5 is a sectional view taken along line a-a of fig. 2, and is a sectional view taken when the shoulders are changed rearward. As shown in fig. 5, the human-shaped toy 2 according to the present embodiment can be put in a posture in which shoulders are bent backward to raise the chest.

That is, the orientation of the left chest part 24 can be changed about the left swing shaft 226 so that the angle formed by the rear surface of the center chest part 22 and the rear surface of the left chest part 24 constituting the trunk decreases. As a result, the left arm is rotated backward by the ball stud 243, and the front surface of the chest portion 20 is deformed to be substantially curved so as to be convex forward, thereby achieving a posture similar to a chest lift.

At this time, the end portion of the left chest part 24 on the front side and closer to the center chest part 22 is in a posture in which the portion once inserted into the inside of the center chest part 22 is pulled out as the direction is changed, and a gap is not easily generated between the left chest part 24 and the center chest part 22. Thereby, the appearance as a continuation of the chest portion 20 is appropriately maintained. The same can be said for right chest part 26 and central chest part 22.

Moreover, the tapered surfaces T are provided at 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 chest center, respectively, so that when the direction is changed with respect to the center chest part 22, smooth connection to the outer surface is achieved while avoiding contact with the center chest part 22. The shape of the tapered surface T is not limited to a linear inclined surface, and may be a curved surface including a rotating body centered on the

swing shafts

226 and 227, or a free curved surface whose volume is reduced so as to avoid contact with the central chest part 22.

Fig. 6 is a sectional view taken along line a-a of fig. 2, and is a sectional view of the shoulders with the shoulders facing forward. The human-shaped toy 2 of the present embodiment can be put into a posture in which both shoulders are contracted forward as shown in fig. 6.

That is, the orientation of the left chest part 24 can be changed about the left swing shaft 226 so that the angle formed by the front surface of the center chest part 22 and the front surface of the left chest part 24 constituting the trunk decreases. Thereby, the left arm is rotated forward by the ball stud 243, deformed so as to narrow the width in the left-right direction of the front surface of the chest portion 20, and assumes a posture as if the shoulder is contracted forward. At this time, the end of the left chest part 24 closer to the front center chest part 22 is inserted further inward than the center chest part 22 with the orientation changed. Thus, when the user intends to assume a posture in which the user contracts the shoulder forward, the volume of the front part of the chest formed by the left chest part 24 and the center chest part 22 is reduced, and the movement of the upper arm part 40 is not hindered, whereby the movable range of the upper arm part 40 can be expanded and the appearance of the chest 20 can be maintained as appropriate. The same can be said for right chest part 26 and central chest part 22.

The human-shaped toy 2 of the present embodiment can take a more various and natural posture because of the ability to take a posture in which both shoulders are retracted forward.

Specifically, as shown in fig. 7, for example, if the chest 20 is formed in a substantially box shape (not in a split structure such as the center chest part 22, the left chest part 24, and the right chest part 26) as in the conventional human toy, both shoulders cannot be contracted forward, and therefore, even if both arms are moved forward (downward in fig. 7), the posture is simply a so-called "forward-looking" posture.

However, as shown in fig. 8, if the chest 20 is configured by dividing the center chest part 22, the left chest part 24, and the right chest part 26 as in the present embodiment, the shoulders can be contracted forward to bring the arms forward, and a posture can be realized in which the arms are overlapped in the chest as if the arms were in an extended state. For example, the beautiful posture of holding the gun can be reproduced on the front.

Further, by providing 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 at the middle between the ball stud 243 as the movable shafts of the left and right arms and the trunk center (the center line L1) (see fig. 3), the impression that the center chest part 22, the left chest part 24, and the right chest part 26 are continuous as the chest in a plan view can be realized.

In addition, in the case where the left swing shaft 226 and the right swing shaft 227 are provided at positions close to the back surface with respect to the center line L2 in the front-back direction of the chest 20 (see fig. 4), by increasing the radius of rotation of the end portions of the left chest part 24 and the right chest part 26 close to the center chest part 22 when the shoulders are swung forward, the tapered surface used to avoid interference with the center chest part 22 is reduced, which contributes to the impression that the center chest part 22, the left chest part 24, and the right chest part 26 are continuous as the chest in a plan view.

[ 2 nd embodiment ]

Next, embodiment 2 to which the present invention is applied will be explained. In the following, differences from embodiment 1 will be mainly described, and the same components as those of embodiment 1 are denoted by the same reference numerals, and overlapping descriptions will be omitted as appropriate.

Fig. 9 is a front view showing an upper half of a configuration example of a human-shaped toy 2B according to the present embodiment.

Fig. 10 is a partially sectional front view showing an example of the internal configuration of the human-shaped toy 2B.

Figure 11 is a left side view of the human toy 2B.

The chest part 20 of the human-shaped toy 2B is divided into a center chest part 22B, a left chest part 24B, and a right chest part 26B. The center chest part 22B is a substantially box-shaped body that opens to the left and right, and connects the upper part 221B and the lower part 222B. The left chest part 24B and the right chest part 26B are substantially bowl-shaped or substantially disk-shaped structures that cover the left and right openings of the center chest part 22B, respectively. That is, the right end of the left chest part 24B covers the outside of the left opening of the center chest part 22B, and the left end of the right chest part 26B covers the outside of the right opening of the center chest part 22B, thereby forming an integral and continuous appearance as the chest part 20.

The connection between the center chest part 22B and the left and

right chest parts

24B and 26B is realized by a ball joint 27 in the present embodiment. The upper arm portion 40 is connected to the left and

right chest parts

24B and 26B by the ball joint 28 in the present embodiment. That is, the human-shaped toy 2B of the present embodiment has a higher degree of freedom in the shoulder and arm than that of embodiment 1.

Of course, the human-shaped toy 2B according to the present embodiment can also be put into a posture in which both shoulders are retracted forward, as in embodiment 1, and the same effects as those of embodiment 1 can be obtained.

That is, if the chest portion 20B is formed in a substantially box shape (if the split structure of the center chest part 22B, the left chest part 24B, and the right chest part 26B is not formed integrally), both shoulders cannot be contracted forward as shown in fig. 12, and therefore, even if both arms are moved forward (downward in fig. 12), the posture is simply called "forward looking".

However, as shown in fig. 13, by the split structure in which the chest part 20B is the center chest part 22B, the left chest part 24B, and the right chest part 26B, if the shoulders are contracted forward and the arms are advanced, a posture in which the arms are extended and overlapped in front of the chest like the extended arms can be realized. For example, an aesthetic posture of holding a sword in front of the chest can be reproduced.

In the present embodiment, the center chest part 22B is connected to the left and

right chest parts

24B and 26B by the ball joints 27, and therefore the shoulder can be contracted not only in the forward oblique downward direction but also in the forward oblique upward direction, the overhead direction, the backward oblique upward direction, and the backward oblique downward direction. The outer surface of the center chest part 22, the outer surface of the left chest part 24, and the outer surface of the right chest part 26 form an appearance in which the chest part 20 is integrally continuous.

[ embodiment 3 ]

Next, embodiment 3 to which the present invention is applied will be described. In the following, differences from embodiments 1 and 2 will be mainly described, and the same components as those in embodiments 1 and 2 are denoted by the same reference numerals, and overlapping descriptions will be omitted as appropriate.

Fig. 14 is a front view showing a configuration example of a human-shaped toy 2C according to the present embodiment.

The human-shaped toy 2C includes a head 10, a chest 20, an abdomen 30, and a waist 60 in this order from top to bottom, and adjacent components 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 70 and a plurality of outer cover portions 80 covering the side surfaces of the waist base 70.

The exterior unit 80 includes: a large hanging part 81 integrally covering the front of the waist part 60 from the umbilical part to the crotch; a left front suspended part 83 and a right front suspended part 84 connected by a ball joint at the upper end of the large suspended part 81 to cover the front of the left and right thigh joint parts; left and right hanging

portions

85 and 86 covering left and right side surfaces of the waist portion 60; and a hip hanging portion 87 (see fig. 17) covering the rear of the waist portion 60. The left and right hanging

portions

85, 86 are supported by a horizontal axis in the front-rear direction at their upper ends so as to be swingable with respect to the waist base 70, and are connected so that their lower ends can be swung up and down.

Fig. 15 is an exploded perspective view showing an example of a connection structure of the waist base 70, the thigh 44, and the hanging part 81. For easy understanding, a part of the waist base 70 is shown in a perspective view, and the connection structure between the waist base 70 and the other hanging portions (the left hanging portion 85, the right hanging portion 86, and the hip hanging portion 87) is omitted from illustration.

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, and the ball stud 71 is connected to the abdomen portion 30 by a ball joint.

Further, a large vertical link 72 is connected to the front upper portion of the waist base 70 so as to be swingable up and down. The rear joint of the large vertical link 72 is connected to the waist base 70 so as to be vertically swingable via a link movable shaft 73. The front joint of the large hanging link 72 is connected by a large hanging shaft 74 at a bearing portion 82 provided at the vertical middle portion of the back surface of the large hanging portion 81, and supports the large hanging portion 81 so as to be swingable upward and downward.

To the left and right sides of the waist base 70, thigh links 76 are respectively connected, and the thigh links 76 have ball studs 75 for ball-joint connection with the thigh portions 44.

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 arc-shaped guide groove 77 provided in the waist base 70. That is, the thigh link 76 can vertically swing the rear joint portion along the guide grooves 77 on the left and right side surfaces of the waist base 70 about the link movable shaft 73.

In the present view, the movable shaft (ball stud 75) for changing the angle of the thigh portion 44 (2 nd component) with respect to the abdomen portion 30 (1 st component) is configured to be provided below the movable shaft (large vertical movable shaft 74) for changing the orientation of the large vertical portion 81 (3 rd component). Further, the movable shaft (ball stud 75) for changing the angle of the thigh portion 44 is provided at a position located more rearward than the movable shaft (large vertical movable shaft 74) for changing the orientation of the large vertical portion 81 and closer to the front and rear of the trunk center (ball stud 71) in plan view.

Next, with reference to fig. 16 to 19, a positional relationship that can be obtained by the parts around the waist portion 60 when the human-shaped toy 2C is changed from the upright posture to the semi-squat, semi-seated and forward-bent posture will be described. In these drawings, parts are shown in a perspective view so that the relative positional relationship can be easily understood, and the illustration of the other parts is omitted.

Fig. 16 is a schematic cross-sectional view showing the positional relationship of parts around the waist 60 in a state where the human-shaped toy 2C is set in an upright posture.

The web portion 30 has a socket portion 31 connected to the ball stud 71 in an internal space therein, and has an opening portion 32 at a front lower end thereof into which an upper end of the hanging portion 81 can be inserted. However, the hanging-down portion 81 in the standing posture is in a posture of being substantially vertically upright, and the upper end thereof is positioned close to the front surface of the abdomen portion 30, covering the opening portion 32. Therefore, when the human-shaped toy 2C is viewed from the front, the presence of the opening 32 is not conspicuous, resulting in a continuous appearance without a large gap in the chest 20 → the abdomen 30 → the waist 60. In the standing posture, the outer cover 80 also forms a continuous appearance without large gaps around the side edges of the waist portion 60 (see fig. 14).

In order to put the human-shaped toy 2C in a half squat and half seated posture from this position, the thigh portion 44 (shown in a perspective state in fig. 16 to 19) must be oriented forward, and the parts around the waist portion 60 must be changed as shown in fig. 17 → 18 → 19. That is, the thigh link 76 swings about the link movable shaft 73 as a rotation axis, and the ball stud 75 descends to the front lower end portion of the waist base 70. At the same time, the thigh portion 44 assumes a laterally-inverted posture with the front surface facing upward.

In order to bend the human-shaped toy 2C forward, the orientation of the thigh link 76 and the thigh portion 44 is changed, and at the same time, the orientation of the abdomen 30 is changed so as to reduce the angle with respect to the waist portion 60 while changing the angle of the large hanging portion 81. That is, the abdomen 30 is tilted forward.

Specifically, as shown in fig. 16, in the large drop link 72 in the upright posture, the front joint is located above the link movable shaft 73 or the ball stud 75. To bend forward from this position, first, as shown in fig. 17 → 18, the large drop link 72 is rotated so that the front joint is lowered with the link movable shaft 73 as the center. Then, the swing axis of the large hanging link 72 moves forward while descending, and the swing axis of the large hanging portion 81 is spaced apart from the abdomen 30. This enlarges the interference preventing space Sp (see fig. 18) between the abdomen portion 30 (part 1) and the large hanging portion 81 (part 3).

Therefore, as shown in fig. 18 → 19, the upper end of the large hanging part 81 is inclined toward the opening part 32 of the abdomen part 30. The abdomen 30 is tilted forward, and the upper end of the hanging part 81 is inserted into the internal space of the abdomen 30. As a result, the abdomen portion 30 can be greatly flexed forward, and a continuous appearance without a large gap from the abdomen portion 30 to the waist portion 60 can be formed when viewed from the front. Further, the tapered surface T is provided at the upper end of the large hanging portion 81 (see fig. 15 and 16), and the following effects are produced: to avoid contact with the opening 32 of the abdomen 30 when the orientation of the hanging part 81 is changed.

The movement and change in the direction of the swing position of the hanging portion 81 also bring about an effect of forming a continuous appearance without a large gap with respect to the appearance around the side edge of the waist portion 60.

Fig. 20 and 21 are schematic perspective views showing parts around the waist portion 60.

Assuming that the swinging position of the large hanging part 81 (the front joint of the large hanging link 72; the large hanging movable shaft 74 (see fig. 15)) is not changed as in the present embodiment, as shown in fig. 20, even when the right thigh part 44 is lifted forward to swing the human toy 2C in a half-squat and half-seated posture, the right front hanging part 84 is lifted, but the large hanging part 81 is kept in the upright posture, and the apparently large interruption part 9 is generated in the right groin part. However, in the present embodiment, as shown in fig. 21, since the hanging portion 81 can be raised forward and leveled, an appearance without a large gap can be formed around the side of the right front hanging portion 84 → the hanging portion 81 → the left front hanging portion 83, and the design of the appearance can be improved.

According to the joint structure of the human-shaped toy of the above-described embodiment, when the 2 nd component (for example, the upper arm portion 40 in fig. 8, the thigh portion 44 in fig. 14) is moved so as to make the angle with respect to the 1 st component (for example, the chest portion 20 in fig. 8, the abdomen portion 30 in fig. 14), the 3 rd component (for example, the left chest portion 24 and the right chest portion 26 in the chest portion 20 in fig. 8, the hanging-up portion 81, the left hanging-down portion 83, and the right hanging-down portion 84 in fig. 14 and 21) can be moved in accordance with the movement of the 2 nd component. For example, when the figure toy is set in a posture in which the 1 st part is a center chest part, the 2 nd part is an arm part, and the 3 rd part is left and right chest parts, and the arms are extended so that both hands overlap in front of the chest, the left and right chest parts (left and right chest parts) can be moved in accordance with the movement of the arms. That is, the trunk (the entire chest in this example) which has been conventionally configured in a box shape is divided into the 1 st component and the 3 rd component, and the 3 rd component is also operated in accordance with the operation of the 2 nd component, whereby the degree of freedom in movement of the joint portion can be increased. Further, the 3 rd component visually couples the 1 st component and the 2 nd component, whereby the continuous appearance without a sense of interruption (a visually large gap) of the coupling of the 1 st to 3 rd to 2 nd components can be formed, and therefore, the reduction of the design charm can be suppressed.

In the present embodiment, the 1 st part and the 3 rd part are configured to partially overlap one another outward and inward when the 3 rd part is turned in a direction to reduce the angle, so that interference between the 1 st part and the 3 rd part can be avoided and a continuous appearance with less visual interruption can be formed.

In the present embodiment, the 3 rd component has a tapered surface near the 1 st component to avoid contact with the 1 st component during rotation, so that interference between the 1 st component and the 3 rd component can be reliably avoided even if the gap between the two components is reduced. In addition, the tapered surface appropriately absorbs the difference in the angle between the outer surface of the 1 st part and the outer surface of the 3 rd part, and even if the 1 st part or the 3 rd part is designed linearly, the continuation of the appearance of both parts can be more smoothly exhibited.

In the present embodiment, since 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 2 nd component 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) for changing the orientation of the 3 rd component in a plan view, even in a configuration in which the 2 nd component is disposed on the side of the 1 st component, the 3 rd component, which is at a gentler angle than the angle of the 2 nd component with respect to the 1 st component and the angle at which the 1 st component is formed, can be disposed between the 1 st component and the 2 nd component. Thus, when the figure toy is observed as a whole, the outer surfaces of the 1 st to 3 rd to 2 nd parts are connected, so that the angle change of the outer surfaces is smoother, and the figure is beautiful.

In the present embodiment, the 1 st part is a chest center part, the 2 nd part is an arm part, and the 3 rd part is a part positioned on the left and right sides of the chest, so that the chest is divided into at least three parts, i.e., the center part and the left and right sides, thereby enabling the shoulders to be retracted forward, and enabling the humanoid toy to reproduce an attractive posture in which the two arms overlap each other and hold the sword or the gun in a state in which the chest is extended.

In the present embodiment, since the 3 rd component has the support portion for supporting the 2 nd component, the 3 rd component can be made to double as the support structure for the 2 nd component.

In the present embodiment, since the movable shaft (for example, the ball stud 75 in fig. 14 and 15) for rotating the 2 nd component is provided below the movable shaft (for example, the large vertical movable shaft 74 in fig. 15) for rotating the 3 rd component in the front view, even in the configuration in which the 2 nd component is disposed below the 1 st component, the 3 rd component having a gentler angle than the angle of the 2 nd component with respect to the 1 st component and a configuration angle of the 1 st component can be disposed between the 1 st component and the 2 nd component. Thus, when the human-shaped toy is observed as a whole posture, the angle change of the outer surface connecting the outer surface of the 1 st to 3 rd to 2 nd parts becomes smoother, and the human-shaped toy looks beautiful.

In the present embodiment, the 3 rd component has an upper portion and a lower portion with respect to a movable shaft (for example, a large vertical movable shaft 74 in fig. 15) for rotating the 3 rd component, and when the 3 rd component is rotated in a direction to reduce the angle, one of the upper portion and the lower portion of the 3 rd component is partially overlapped with the other one of the upper portion and the lower portion of the 3 rd component toward the outside of the 1 st component and the other one of the upper portion and the lower portion thereof is partially overlapped with the inside of the 1 st component (for example, fig. 16 to 19).

In the present embodiment, the 1 st part is an abdomen part (for example, the abdomen part 30 in fig. 14), the 2 nd part is a leg part (for example, the thigh part 44 in fig. 14), and the 3 rd part is a waist part appearance part (for example, the hanging part 81 in fig. 14), so that the position of the waist part appearance part as the 3 rd part can be changed in accordance with the change in the position of the leg part as the 2 nd part. Thus, for example, the design parts around the waist can be changed to appropriate positions according to the posture of the user who has been put in a half-squatting and half-sitting posture, and the beautiful appearance can be naturally realized.

In the present embodiment, the 3 rd component is configured to swing with respect to the 1 st component, and further includes a link component (for example, a large hanging link 72 in fig. 15) having one end supporting a swing shaft of the 3 rd component and the other end pivotally supported, and the swing shaft of the 3 rd component can be adjusted in position vertically by swinging the link component vertically with the other end as a shaft center, so that the position of the swing shaft of the 3 rd component (for example, a large hanging portion 81 in fig. 14) can be changed. This makes it possible to expand the position or posture of the 3 rd component, which can be changed, and to realize various postures of the human-shaped toy.

In addition, in the present embodiment, when the 2 nd part is rotated so as to reduce the angle, the interference preventing space between the 1 st part and the 3 rd part can be enlarged by swinging the link part downward, and therefore, as the 2 nd part is rotated, the link part is swung downward, and the entire 3 rd part moves in a direction away from the 1 st part, thereby enlarging the interference preventing space. The enlargement of the interference prevention space is an enlargement of a space for changing the 3 rd component at a position not interfering with the 1 st component, and makes it easy to change the orientation of the 3 rd component in a direction of reducing an angle with respect to the 1 st component. As a result, the angle of the 3 rd part with respect to the 1 st part can be further reduced as viewed from the human-shaped toy as a whole.
