Description

  The present invention relates to a shoulder joint structure of a doll toy and a doll toy, and more particularly to a shoulder joint structure capable of more realistic three-dimensional joint movement and a doll toy provided with the shoulder joint structure.

  Of the joint parts of the doll toy that can reproduce various postures and movements, the shoulder joint structure to which the arm part can be attached can rotate the arm base to reproduce more realistic arm and shoulder movements A structure in which a scapula part member that connects the shoulder part and the arm part is interposed is proposed instead of a structure that merely connects (for example, Patent Documents 1 to 3).

  In the technique described in Patent Document 1 or 2, a scapula member is provided on a rotation shaft that is provided at a shoulder joint position of the upper body portion of the doll toy and in which a scapula member is accommodated, and hangs substantially at the center of the bottom surface of the recess. Is supported on the pivot shaft so as to be inserted from above the concave portion, so that the scapula member is rotated inward and outward.

  The technique described in Patent Document 3 is configured as a two-part body in which the upper body part of the doll toy can be divided into front and rear, and a recess is provided at the shoulder joint position of the upper body part which is divided into two parts. The shoulder blade member is fitted into the recess so that the pivot shaft provided at the top and bottom of the shoulder blade member is pivotally supported by the bearing hole provided at the top and bottom of the recess in a state where the shaft is divided into two. Then, the scapula member is configured to addend and abduct by joining the upper body parts divided into two.

  By interposing the scapula member at the shoulder joint position, not only the arm can be rotated, but also the action of squeezing the shoulder by adduction (for example, volleyball receive posture), and expanding the shoulder by abduction It is possible to take (chest) action (for example, a volleyball toss posture or a posture in which hands are folded behind the head), and more realistic three-dimensional joint movement is possible.

  According to the first or fourth aspect of the present invention, it is possible to provide a shoulder joint structure and a doll toy capable of more realistic three-dimensional shoulder joint movement without impairing real appearance and aesthetic appearance.

  In particular, the shoulder blades placed at the shoulder joint position not only allow the arm to be rotated, but also the action of squeezing the shoulder by adduction (for example, the posture of a volleyball receive) or the abduction. A widening (chesting) action (for example, a volleyball toss posture, a posture of crossing hands behind the head, etc.) can be taken, and more realistic three-dimensional joint movement is possible.

  In addition, the scapula member that enables articulation of adduction and abduction is arranged so as to enter the shoulder attachment recess of the upper body part from the side direction, so that it is exposed from the shoulder attachment recess. It does not impair the real appearance.

  In addition, since the attachment of the upper body portion to the shoulder attachment recess is a configuration that is inserted from the side surface direction, the upper body portion can be attached without being divided into two parts. Accordingly, the dividing line associated with the division does not occur in the upper body portion, so that the real appearance and aesthetic appearance are not impaired.

  According to the second aspect of the present invention, the direction in which the scapula member is inserted into the shoulder attachment recess of the upper body portion from the side direction coincides with the direction in which the scapula attachment member is attached to the scapula attachment recess. The scapula member can be attached very easily.

  According to the third aspect of the present invention, since the dividing line associated with the division does not occur in the upper body part which is the main component of the doll toy, the real appearance and the aesthetic appearance are not impaired. Therefore, it is not necessary to hide the dividing line with clothes or the like, and post-processing such as putty filling is unnecessary.
