Description

  The present invention relates to a joint structure of a doll and a doll having the joint structure.

  As is well known, a wide variety of joint structures have been developed in dolls and robots in order to be able to reproduce poses close to the human body.

  For example, Patent Document 1 described later includes a first joint member and a second joint member. The first joint member has a support shaft projecting vertically and a connection hole is formed in the left-right direction. The second joint member is formed with a connection shaft that is rotatably connected to the connection hole of the first joint member, and an attachment hole is formed in the front-rear direction. The first joint member is connected to the first joint member so that it can be rotated as the upper and lower support shafts on the joint surface of the first half body and the second half body of the first member composed of the first half body and the second half body. Is pivotally supported and is attached to the first member so as to be pivotable about the support shaft, and the second joint member has a mounting hole that is pivotable on the mounting shaft of the second member. A joint device is disclosed that is attached and attached to a second member so as to be pivotable about an attachment axis. To have.

  However, the joint device described in Patent Document 1 does not have a mechanism for restricting the rotation between the second joint member and the second member, and therefore, when applied to a relatively small doll, The second member can be held in a fixed pose by the frictional force generated on the contact surface between the two joint members and the second member, but when applied to a large doll, Since the weight increases, there is a problem that the second member cannot be held in a certain pose only by the frictional force generated on the contact surface between the second joint member and the second member.

  On the other hand, in Patent Document 2 below, a pair of engaging plates that are mounted on a shaft are elastically supported by a synthetic resin ring that is mounted coaxially with the engaging plate in a direction in which the plates are pressed against each other. The corrugated engaging concave and convex portions that mesh with the plate joining end surface are radially provided from the shaft mounting position toward the plate edge, and the armbands are respectively attached to the plate. A mannequin doll joint is disclosed.

  According to the joint for a doll described in Patent Document 2, since the engagement uneven portion for restricting the rotation is formed on the pair of engagement plates, even if applied to a large doll such as a mannequin Although it can be held in a fixed pose due to the engagement of the mating plates, there is a problem that the number of parts is increased and the structure becomes complicated because both the engaging plates are pressed against each other by tightening the screws. .

Further, in any of the above joint structures, since the members are connected by screws, the screws are exposed as the appearance of the doll, and there is a problem that the aesthetic appearance is greatly impaired.
