[Embodiments of the present invention]
In this embodiment, a shoulder joint structure of a doll toy will be described.

  FIG. 1 is a perspective view showing the overall configuration of a doll toy for explaining an embodiment of the present invention.

  A doll toy 1 shown in FIG. 1 includes a head member 2, a torso member 3, a waist member 4, an upper arm member 5, a lower arm member 6, a hand member 7, a thigh member 8, a leg member 9, And a foot member 10.

  An intermediate part 11 is provided at a connecting portion (shoulder joint part) between the trunk member 3 and the upper arm member 5, and the upper arm member 5 is rotatable to the shoulder portion of the trunk member 3 through the intermediate part 11. Is attached.

  FIG. 2 is an exploded perspective view of the shoulder joint structure of the doll toy 1 of FIG.

  The body member 3 includes a front body member 31 and a rear body member 32 that are formed in two. The front body member 31 and the rear body member 32 are respectively formed with arc-shaped concave portions 31a and 32a in which one opening is formed by joining them. The recesses 31 a and 32 a form a substantially elliptical opening in the shoulder portion of the body member 3 by integrally joining the front body member 31 and the rear body member 32.

  A cylindrical mounting shaft 31b is formed on the inner side surface of the front barrel member 31 so as to project in the front-rear direction, and a cylindrical shape is inserted on the inner side surface of the rear barrel member 32 in the front-rear direction. A mounting hole 32b is formed in a protruding manner.

  The intermediate part 11 is disposed in an opening formed in the shoulder portion of the body member 3 by the recesses 31a and 32a, and is rotatably connected to the body member 3 by a ball joint. The ball joint includes a ball 12c and an accommodating portion 11a that accommodates the ball 12c in a rotatable manner. In the illustrated example, the ball 12c is attached to the shoulder member 3 (in the present embodiment, on the shoulder of the trunk member 3). In the recesses 31 a and 32 a to be formed, the accommodating part 11 a is provided in the intermediate part 11. If the outer shape of the intermediate part 11 is the shape of the muscle around the base of the arm or around the shoulder in the human body, the connection of the muscles from the trunk to the upper arm can be expressed without a sense of incongruity.

  In the illustrated example, the upper arm member 5 is also rotatably connected to the intermediate part 11 by a ball joint including the ball 5a and the accommodating portion 11b.

  The body member 3 is provided with a shaft member 12 having balls 12c. The shaft member 12 includes an attachment portion 12a attached to the attachment shaft 31b and the attachment hole 32b, and a support shaft 12b extending from the attachment portion 12a in the left-right direction of the body member 3, and a ball 12c is provided at the tip of the support shaft 12b. Is provided.

  An accommodation portion 11a for accommodating the ball 12c is formed on one side surface of the intermediate part 11, and an accommodation portion 11b for accommodating the ball 5a is also formed on the other side surface.

  3 is an assembled perspective view of the shoulder joint structure of FIG.

  As shown in FIG. 3, the upper arm member 5 connected to the intermediate part 11 and the intermediate part 11 passes through the ball 12c and moves up and down the body member 3 by connecting the body member 3 and the intermediate part 11 via a ball joint. In addition to the Z axis extending in the direction, it can be rotated around two axes (X axis and Y axis) orthogonal to the Z axis. Thereby, the rotation range of the upper arm member 5 can be expanded.

  4 is an assembled plan sectional view of the shoulder joint structure of FIG.

  As shown in FIG. 4, the ball joint ball 12 c that connects the body member 3 and the intermediate part 11 passes through the center of the neck 3 a to which the head member 2 is connected in the front-rear direction of the body member 3. Is provided at a position f in front of the center line c in the width direction.

  By providing the ball joint ball 12c for connecting the body member 3 and the intermediate part 11 at a position closer to the front of the body member 3, the rotational range of the upper arm member 5 can be shifted forward, for example, Movement that imitates the movement of a person such as arms folded is possible.

  Further, a ball joint ball 12c for connecting the body member 3 and the intermediate part 11 is provided in the body member 3, and an accommodating portion 11a for accommodating the ball 12c is provided in the intermediate part 11, and the ball is applied to the intermediate part 11. The interference between the intermediate part 11 and the body member 3 can be avoided as compared with the case where the body member 3 is provided with a housing part for housing the ball. As a result, the rotation range of the intermediate part 11 can be expanded, and consequently the rotation range of the upper arm member 5 can be expanded. In particular, in the present embodiment, since the ball joint composed of the accommodating portion 11a and the ball 12c is provided on the side surface of the intermediate part 11, the intermediate part 11 and the body member 3 (specifically, an opening formed in the shoulder portion). It is a structure that can more easily avoid interference with the peripheral edge of the portion. Further, the interference can be further avoided by providing the ball 12c at the tip of the support shaft 12b extending in the left-right direction of the shaft member 12. Even if the gap between the outer surface of the intermediate part 11 and the peripheral edge of the opening formed in the shoulder portion of the trunk member 3 is reduced by the combination of these structures, the intermediate part 11 or the upper arm member 5 and the trunk member 3 are reduced. Since the movable range with respect to the trunk member 3 of the intermediate part 11 and the upper arm member 5 until the interference (specifically, the peripheral edge of the opening formed in the shoulder) can be made relatively large, the outer surface of the intermediate part 11 And a shoulder joint structure having a relatively large movable range with a small gap between the peripheral edge of the opening formed in the shoulder portion of the body member 3 and a small appearance.

  It should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
