Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can deform not only the elbows and knees but also the bases of the arms and legs so that they can be bent or opened to a shape close to human's natural movements, and further deformed. The present invention relates to a structure of a doll's arm or leg which has a good shape-retaining property and can keep its shape stable.

[0002]

2. Description of the Related Art Conventionally, the structure in which the elbows and knees can be bent by the structure of the arms and legs of a doll is disclosed in, for example, Shokai 62-164.
It is known as described in Japanese Patent Publication No. 092. This invention is the structure of the doll's arms and legs that allows the elbows and knees to flex freely and the angle of opening at the base of the arms and legs can be freely adjusted. The arms and legs of this doll are made of soft synthetic resin. The core material inserted into this arm or leg is divided into elbows or knees, and these divisions are connected with a soft metal strip so that the arms and legs can be connected together. Is attached to the upper end of the core material by projecting a vertical axis having a flange at its tip and inserting the vertical axis into a through hole provided at the base of the arm or foot of the doll body. As a result, the arms and legs can be freely opened.

[0003]

However, the arms and legs of the doll thus constructed do not hinder the operation of rotating in the front-rear direction at the base of the body, but the operation of opening them outwardly. Abruptly, or after bending outward in this way, the external force may be increased by bending when bending the arms, legs, elbows or knees in the anterior-posterior direction. It was added concentrated on the axis, and the concentrated force broke the attachment part on the vertical axis, and there was a drawback that the arms and legs were torn from the body of the doll. Therefore, the object of the present invention is to
In order to solve such a problem, an object is to provide an improved doll arm and leg structure.

[0004]

According to the present invention, a core material which can be bent at an appropriate position is inserted into an arm or foot of a doll formed of a soft synthetic resin material, and the core material is close to the upper end. A weak point is formed by providing a thin portion, a narrow portion, a through hole, or the like at a position, and the vertical axis having a flange at the tip of the upper end of the core material is projected so that the doll can freely open. After the arms or legs are formed and the weak points of the core material inserted into the arms or legs are bent to divide the core material into upper and lower parts, the doll body is provided at the base of the arms or feet. The vertical axis is fitted into the small hole to integrally attach the body and the arm or leg of the doll.

[0005]

In the arm or foot of the present invention thus constructed, the vertical axis protruding at the upper end is inserted into the small hole provided in the body to be coupled, and the arm or foot can be rotated back and forth, left and right. It can be opened outward. Even when a strong force applied especially when opening to the outside in such an operation is concentrated on the vertical axis, this force is not applied to the core material because the core material is cut in a transverse shape in advance at the weak point position. Since it is divided into upper and lower parts and almost no force is applied to the vertical axis, the vertical axis is not broken. Then, by forming the weak point in the thin portion, the narrow portion or the through hole, the force transmitted to the vertical axis is dispersed when the arm or leg is opened outward at the base, and breakage of the vertical axis is prevented. Reduce. Moreover, the cutting of the core material at the weak point is performed after molding the arms and legs, so there is no problem in forming the arms or legs,
The core material is completely embedded in the soft synthetic resin and does not hinder the function of the core material.

A weak point 6 is provided by narrowing or further forming a circular hole as shown in FIG. 3, and a hemispherical bulging portion 7 is formed on the inner side of the weak point 6 and a vertical groove 8 is provided at the center thereof. A horizontal axis 9 is laid across the vertical groove 8 and the lower end of the vertical axis 10 is pivoted on the horizontal axis 9. The vertical axis 10 has a length such that the tip projects from the bulging portion 7, and a disk-shaped flange 11 is fixedly provided on the head thereof.

Then, the core materials 2 and 3 connected by the metal strips 4 are inserted into a soft synthetic resin material such as polyvinyl chloride resin, and the arm 1a of the doll shown in FIG. 2 and the foot 1b of the doll shown in FIG. Are integrally formed. A hemispherical mounting portion 12 is formed at the upper end of the inner side surface of the arm 1a and the foot 1b, and a long hole 13 is opened in the mounting portion 12 so that the vertical axis 10 is loosely fitted in the long hole 13. It is rotatable in the direction of the arrow. The arms 1a and the legs 1b thus formed are bent several times in the lower position of the bulging portion 12, that is, in the vicinity of the weak points 6 provided on the core material 2, whereby the weak points 6 are moved to the positions shown in FIGS. Cut 14 transversely as shown in FIG.

FIG. 5 is an exploded view of the body of the doll to which the arms 1a and the legs 1b are assembled. As shown in FIG. 6, the body is divided into an upper body 15 and a lower body 16, and the upper body 15 and the lower body 16 are also divided into front half portions 15a and 16a and rear half portions 15b and 16b, respectively, so that the inside is hollow. To form. Further, a concave spherical base portion 18 having a small hole 17 formed at the center thereof is provided on both shoulders of the upper body 15, and a circular hole 19 is formed at the center of the lower end of the upper body 15.

On the other hand, a neck portion 21 having a flange 20 on the upper surface thereof is projectingly provided at the upper ends of the front half portion 16a and the rear half portion 16b of the lower body 16, and the neck portion 21 is engaged with the circular hole 19 of the upper body 15. The upper body 15 and the lower body 16 are integrally and rotatably connected. Further, a concave spherical base 23 having a small hole 22 formed in the center of each of the left and right sides of the lower body 16 is formed.
Is provided.

When the front half portion 16a and the rear half portion 16b of the lower body 16 are combined and assembled, the left and right roots 23,
23 are fitted with the mounting portions 12 of the feet 1b and 1b, respectively, and the vertical axis 1
0 is inserted into the small hole 21, and the flange 11 is locked in the lower body portion 16. Similarly, the front half 15 of the upper body 15
When the a and the rear half portion 15b are combined and assembled, the attachment portions 12 of the arms 1a and 1a are fitted into the left and right joints 18 and 18, respectively, and the vertical axis 10 is inserted into the small hole 17, and the flange 11 is inserted into the upper body 15. As shown in FIG. 6, when the upper body 15 is assembled, the flange 20 provided on the upper end of the lower body 16 that has been assembled in advance is fitted into the circular hole 19 provided on the lower end of the upper body 15. Thus, the upper body 15 and the lower body 16 are integrated.

The doll A assembled in this manner is rotated about the vertical axis 10 when raising the arm 1a forward, as shown by the alternate long and short dash line in FIG. When bending with an elbow as shown in FIG. The knee of the arm 1b is also bent in the same manner. When the arm 1a and the foot 1b are opened from the solid line position in FIG. 7 as indicated by the alternate long and short dash line, the vertical groove 10 can move the elongated hole 13 to open the open angle.

A strong external force is applied to the upper ends of the arms 1a and legs 1b when bending the arms 1a and legs 1b outwardly, as well as when bending the arms 1a and legs 1b. , The external force is not concentrated on the vertical axis 10 due to the weak point 6 provided at the upper end of the core 2 being cut 14 in a transverse shape, and therefore the external force is not concentrated on the vertical axis 10.
Does not break. Therefore, the arm 1a and the foot 1b are shown in FIG.
It is possible to continue to hold the posture that is opened to the outside as shown in (1), the posture can be changed to an arbitrary shape as necessary, and the hand 1a and the foot 1b are never torn.

Even if the core material 2 is cut 14 at the weak point 6 in a transverse shape, the core material 2 has already been cut.
Since it is cut after being insert-molded in b, the function and strength of the arm 1a and the foot 1b are not impaired.
That is, the weak point 6 is only required to hold the core material 2 until the arms 1a and the feet 1b are integrally molded.

By forming the weak point 6 in the thin portion, when the base of the arm or leg is opened outward, there are few portions where the edges divided at the cut 14 portion overlap each other. In addition, it is possible to easily perform the opening angle operation without causing a phenomenon such as a so-called lever action, that is, a squeezing, and the vertical axis 10 is not broken.

Further, by forming the weak point 6 in the narrow width portion, the width is narrower than that in the case where the weak point 6 is formed by the thin portion at the time of opening the base of the arm or foot outward. Just reduce the strain, vertical axis 10
It is possible to further reduce the force transmitted to.

Further, by forming the weak point 6 in the through hole, the cross-sectional area of the cut 14 can be made smaller than that of the weak point 6 formed in the thin portion or the narrow width portion. The force applied to the vertical axis 10 at the time of bending to open the base of the foot or leg outward can be reduced more than any of the above.

[0017]

As described above, the arms and legs of the doll of the present invention are divided into upper and lower parts by cutting the weak points of the core material inserted in the central portion before assembling it into the body of the doll. By doing so, the external force applied when opening or turning at the base of the arm or leg, or when bending the elbow or knee is dispersed up and down the core material, and almost all of it is on the vertical axis of the attachment part. Since no force is applied, breaking of the vertical axis provided at the base of the arm or leg is prevented, and the arm or leg does not separate from the base of the body of the doll, so you can freely change the posture of your hands and feet. Is what you can do.
