Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a shoulder joint structure for a doll that can increase the range of motion of arm members.

(Prior art and its problems) Conventionally, in the shoulder joint structure for dolls, the arm members are rotatably fitted into attachment holes formed in the shoulders of the body member, so the range of movement of the arm members is limited. can only be rotated 360° along the sides of the body member. In addition, the limited range of motion of the arm members not only impairs realism but also poses practical difficulties such as difficulty in putting clothes on the doll, and a solution to this problem is desired. Ta.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned viewpoints, and is particularly a doll with a large range of motion, in which the movement of the arm members is not limited to rotational movement, but also opening and closing movement. The purpose is to propose a shoulder joint structure for use.

(Technical means to solve the problem) As a technical means to solve the above problem,
The shoulder joint structure for a doll according to the present invention is characterized by having the following requirements.

(a) A substantially spherical fitting portion is formed at the base of the arm member, and a support shaft is provided to protrude from the fitting portion in a direction substantially perpendicular to the axis of the arm member.

(b) An attachment hole for attaching the arm member is formed in the shoulder portion of the body member, and a guide groove is provided on the inner periphery of the attachment hole in which the support shaft is slidably engaged. be provided around the area.

(Operations and Effects of the Invention) As described above, according to the shoulder joint structure for a doll according to the present invention, the arm member fitted into the attachment hole provided in the shoulder of the body member The supporting shaft protruding from the mounting hole engages in the guide groove provided on the inner periphery of the mounting hole, and the supporting shaft can slide in the guide groove.
At this time, the arm member can be rotated relative to the torso member. In addition, the arm members can be rotated around the support shaft, allowing opening and closing movements, improving the realism of the doll.
It also makes tasks such as changing clothes easier.

(Example) Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

In the figure, numerals 1 and 1 indicate arm members of a synthetic resin doll. The arm members 1, 1 have substantially spherical fitting parts 2, 2 integrally formed at the base thereof, and the fitting parts 2, 2 are supported in a direction substantially perpendicular to the axis of the arm members 1, 1. Shafts 4, 4 are provided protrudingly. Reference numerals 5 and 5 indicate core members made of wire or the like housed inside the arm members 1, 1, and when the arm members 1, 1 are bent and deformed by the core members 5, 5, The deformed state can be maintained reliably. Note that the core members 5, 5 are not limited to this, and may be formed in a coil shape, for example.

The body member 6 made of synthetic resin, to which the arm members 1, 1 are attached, has arm members 1, 1 in the vicinity of both shoulder parts 6a, 6a.
circular attachment holes 7, 7 into which the fitting parts 2, 2 are attached;
are formed, and support shafts 4, 4 provided on the fitting portions 2, 2 are formed on the inner periphery of the attachment holes 7, 7.
Guide grooves 8, 8 are provided around the periphery, and the guide grooves 8, 8 are slidably engaged with each other.

Since the shoulder joint structure for dolls is configured as described above, when attaching the arm members 1, 1 to the body member 6, first, attach the approximately spherical joints provided at the bases of the arm members 1, 1. The fitting parts 2, 2 are fitted into the mounting holes 7, 7 of the body member 6, and the fitting parts 2, 2 are fitted into the guide grooves 8, 8 provided around the inner peripheral surface of the mounting holes 7, 7. The supporting shafts 4, 4 formed on the shafts 2, 2 are engaged with each other. Thereby, the arm members 1, 1 can be easily attached to the trunk member 6.

According to the shoulder joint structure for a doll as described above, the arm members 1, 1 attached to the torso member 6 are attached to the attachment holes 7, 7 formed in the vicinity of the shoulders 6a, 6a of this torso member 6. A support shaft 4 protruding from the fitting portions 2, 2 at the base of the arm members 1, 1 in guide grooves 8, 8 provided around the inner circumferential surface;
4 is engaged. Therefore, the support shafts 4, 4 can be slid and rotated along the guide grooves 8, 8, and at the same time, the arm members 1, 1 can be rotated forward and backward,
Can be rotated up and down. In addition, the arm member 1,
Since the doll 1 can be swung around the support shafts 4, 4, it can also be opened and closed, giving the doll a wide range of poses and improving the sense of realism. Further, since the core members 5, 5 made of wire are housed inside the arm members 1, 1, the arm members 1, 1 can be bent and their deformed state can be reliably maintained.

In addition, although the shoulder joint structure was explained in detail in the above example, it is not limited to this.
For example, it can also be applied to the neck, legs, etc.
