Below, as a joint structure according to the present embodiment, a shoulder joint structure in which an arm portion 103b is connected to a chest portion 102 by a spherical connecting member (ball joint) will be described. However, there is no intention to limit the present invention, and the joint structure described below is not limited to shoulder joints, and can be applied to other joints such as hip joints, elbow joints, and knee joints that connect legs. It is also possible to

<Structure of upper body including arms>
Next, with reference to FIG. 2, attachment of the arms 103b to the upper body of the doll-type toy 100 according to this embodiment will be described. FIG. 2(a) is a perspective view showing the chest 102, arm 103b, abdomen 104, and waist 105 of the upper body. FIG. 2(b) is an exploded view of the arm 103b including the shoulder joint. The arm portion 103b corresponds to the left arm of the doll-type toy 100, but the arm portion 103a corresponding to the right arm has the same configuration, and detailed description thereof will be omitted.

As shown in FIG. 2A, the arm 103b is connected to the chest 102 by a spherical connection (ball joint). That is, the shoulder joint according to this embodiment connects the arm portion 103b to the chest portion 102 so as to be rotatable with a ball joint. However, it is not intended to limit the invention, and instead of the spherical connecting portion, other shaped connecting portions may be employed.

Further, as shown in FIG. 2(b), the arm portion 103b includes parts 201-204. The part 204 is further composed of a plurality of parts, but detailed description thereof will be omitted.

A shaft for rotating the connected parts is generally inserted into the ring-shaped connecting portion. In this case, the upper arm side shoulder part having the shaft is generally formed of two parts. Parts formed from two parts will have seams when combined. For example, when such a structure is used for the shoulder joint, a seam is formed in a part of the shoulder, giving an unnatural impression. Therefore, according to the present embodiment, by forming the upper arm side shoulder part 201 into which the ring-shaped connecting part 302 is fitted as a single part, a shoulder joint free from the seams described above is realized. A detailed configuration such as a combination will be described later.

<Detailed configuration of joints>
Next, with reference to FIG. 3, the detailed configuration of the joints of the doll-type toy 100 according to this embodiment will be described. FIG. 3(a) shows an exploded view of the shoulder joint according to this embodiment, and FIG. 3(b) shows the shoulder joint in a state in which two parts according to this embodiment are combined.

As shown in FIG. 3A, the shoulder movable part 202 is formed with a spherical connecting portion 301 and a ring-shaped connecting portion 302 . The spherical connecting portion 301 is rotatably connected to the chest 102 . The ring-shaped connecting portion 302 is rotatably fitted and connected to the upper arm side shoulder part 201 . A concave portion 303 having an opening for fitting the ring-shaped connecting portion 302 of the shoulder movable part 202 is formed on one side of the upper arm side shoulder part 201 . Riding portions 304a and 304b, into which the ring-shaped connecting portion 302 is rotatably fitted, are formed on the inner side surface of the concave portion 303. As shown in FIG.

The riding portions 304a and 304b are fitted into the rings (holes) of the ring-shaped connecting portion 302 from both sides, and when fitted into the ring-shaped connecting portion 302, are positioned along the inside (inner diameter) of the ring, It functions as a rotating shaft that allows the portion 103b to rotate up and down. Also, the riding parts 304 a and 304 b function to hold the connected shoulder movable part 202 to the upper arm side shoulder part 201 . FIG. 3(b) shows how the shoulder movable part 202 is fitted into the upper arm side shoulder part 201. FIG.

The upper arm side shoulder part 201 is formed including a concave portion 303 and an upper arm side connecting portion 305 . The upper-arm-side connecting portion 305 is formed at the end opposite to the end where the recess 303 is formed, and is connected to the part 204 that is part of the arm 103b. In the present embodiment, the connection portion with the pearl 204 is fitted and fixed, but there is no intention to limit the present invention. good. This allows for a wider variety of motions and poses.

<Upper arm side shoulder part>
Next, with reference to FIG. 4, the detailed configuration of the upper arm side shoulder part 201 according to this embodiment will be described. FIG. 4(a) shows a perspective view of the upper arm side shoulder part 201. FIG. FIG. 4(b) shows a plan view of the upper arm side shoulder part 201. FIG.

As shown in FIG. 4A, the riding portions 304a and 304b formed in the recessed portion 303 of the upper arm side shoulder part 201 are formed in a convex shape on the inner side surface of the recessed portion 303, It is formed. The riding portions 304a and 304b are formed on the inner side surfaces of the recessed portion 303 so as to face each other. Also, the riding portions 304 a and 304 b are formed in a semicircular shape matching the curvature of the ring of the ring-shaped connecting portion 302 . As a result, the riding portions 304a and 304b can rotatably hold the movable shoulder part 202 with the inner wall of the deepest portion of the recessed portion 303, and function as a rotation axis when the movable shoulder part 202 rotates. Details will be described with reference to FIG.

Also, as shown in FIG. 4B, the crossing portions 304a and 304b are formed with different widths. This is for securing the mold strength when forming the upper arm side shoulder part 201 . In other words, the strength of the die is ensured by providing flat surfaces on both sides of the riding portion 304a. However, although the forming widths are different, the two riding parts 304a and 304b are formed in a semicircular shape with the same curvature, which does not affect the function of the shoulder movable part 202 as a rotating shaft.

<Cross section of joint>
A side sectional view of the joint according to the present embodiment will be described below with reference to FIG. 5 . FIG. 5(a) shows a cross section along AA' in FIG. 3(b), and FIG. 5(b) shows a cross section along BB' in FIG. 3(b).

FIG. 5(a) shows a state in which the shoulder movable part 202 has climbed over the riding parts 304a and 304b and is fitted into the upper arm side shoulder part 201. FIG. The riding parts 304a and 304b are arranged at the inner part of the concave part 303 of the upper arm side shoulder part 201, which is the lower side in FIG. 5(a). By providing the riding parts 304a and 304b in the inner part of the recess 303 in this way, the ring part of the ring-shaped connecting part 302 is sandwiched between the riding parts 304a and 304b and the inner wall of the upper arm shoulder part 201. It is possible to hold the shoulder movable part 202 and prevent the shoulder movable part 202 from rattling in the vertical direction.

On the other hand, it is also conceivable that the riding portions are provided on the opening side of the concave portion 303, on the left and right sides of the upper side in FIG. 5(a). However, when provided on the upper side, the ring portion of the ring-shaped connecting portion 302 can be sandwiched and held between the inner wall of the upper arm side shoulder part 201 compared to when provided on the lower side (rear side). Unable to do so, rattling occurs. Furthermore, when the riding portion is provided above the concave portion 303, an undercut occurs when the mold is opened and closed. end up

In order to avoid undercuts, it is also conceivable to form the jump-over from the upper side to the lower side instead of forming it only on the upper side. By forming in this way, it is possible to prevent undercutting, and furthermore, to prevent rattling as described above. However, if the riding portion is formed over the top and bottom, the fitting with the shoulder movable part 202 becomes hard, and the shoulder movable part 202 cannot be easily fitted into the upper arm side shoulder part. In this way, the riding parts 304a and 304b formed at the inner part of the recess 303 according to the present embodiment can also solve the problem that arises when the riding parts are formed on the upper side or when they are formed vertically. is.

Also, FIG. 5(b) shows how the riding portion 304b is fitted along the inner diameter of the ring when the movable shoulder part 202 is fitted to the shoulder part 201 on the upper arm side. In this way, the riding portion 304b is formed in a semicircular shape, and is formed in accordance with the curvature of the ring of the ring-shaped connecting portion 302. As shown in FIG. Therefore, the shoulder movable part 202 can be rotated in the direction of the arrow along the contour of the riding portion 304b. In addition, FIG. 5B shows how the ring portion of the shoulder movable part 202 is sandwiched and held between the riding portion 304b and the inner wall of the upper arm side shoulder part 201, as described above. Thereby, rattling in the vertical direction can be prevented.

<Coupling of multiple parts>
Next, with reference to FIG. 6, a comparison between a joint made up of a plurality of parts as a comparative example and the joint according to the present embodiment will be described. FIG. 6(a) shows the structure of a shoulder joint as a comparative example. FIG. 6(b) shows the structure of the shoulder joint according to this embodiment.

As shown in FIG. 6A, in the comparative example, shoulder parts 601 and 603 on the upper arm side are fitted from the left and right sides of the movable shoulder part 602 having a ring-shaped connecting portion. The upper arm shoulder part 601 is formed with a shaft 604 that serves as a rotation axis of the arm connected to the upper arm shoulder parts 601 and 603 . The shaft 604 is inserted into the ring portion of the shoulder movable part 602 and fitted into the concave portion formed in the upper arm side shoulder part 603 to combine these three parts.

Thus, in the comparative example, the upper arm side shoulder part is formed of two parts. Therefore, when the upper arm shoulder parts 601 and 603 are combined, a seam 605 is formed. The seams 605 appear at the joints of the doll-type toy, here at the shoulder joints, and give an unnatural impression compared to real people and animals. Therefore, it is desirable to reduce seams caused by combining such multiple parts as much as possible. However, the ring-shaped connecting portion is generally connected by inserting a shaft in the same manner as in the comparative example, and in that case, it is easier to form the parts by constructing the ring-shaped connecting portion with a plurality of parts. In other words, when adopting a configuration in which the shaft is inserted, it is not preferable to form the upper arm side shoulder part from a single part because it makes the part manufacturing process more complicated.

Therefore, according to this embodiment, as shown in FIG. This is achieved by fitting the In addition, the riding portion is formed in a semicircular shape that matches the curvature of the ring of the movable shoulder part 202, and functions as a shaft that allows the parts to rotate along the outer shape. By forming the upper arm side shoulder part 201 from a single part in this manner, it is possible to form a joint portion that does not have a seam as described in the comparative example.

As described above, the doll-shaped toy according to the present embodiment includes a first part partially having a ring-shaped connecting portion, and a concave portion forming a joint with the first part and into which the ring-shaped connecting portion is fitted. and a second part. Further, the second part is formed as one part, and a riding portion for rotatably holding the ring-shaped connecting portion is formed on the inner side surface of the recess. As a result, it is possible to reduce the number of parts while realizing a rotatable joint structure in the doll-type toy, and to realize an appearance with a more natural impression.

<Modification>
The present invention is not limited to the above-described embodiments, and various modifications and changes are possible within the scope of the gist of the invention. In the above embodiment, an example in which the joint structure is applied to the shoulder joint has been described, but the present invention is not intended to be limited and may be applied to other sites. For example, it can also be used for joints such as hip joints, elbow joints, and knee joints that connect legs. In addition, although an example in which a spherical connecting portion (ball joint) is provided on one side of the connecting member according to the above embodiment has been described, any connecting portion can be adopted as long as the connected parts are rotatable. may be It is desirable to construct a joint that is appropriate for the joint to which it is applied.

Also, the shape of the doll-type toy (doll body) is not particularly limited, and includes various shapes such as people, animals, robots, insects, dinosaurs, and virtual creatures.
