[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference symbol A indicates a doll A formed by the method for manufacturing a doll body according to the present invention, and the doll A has a body 1a and an arm formed of a material having elasticity. After inserting the pre-assembled skeletal portion 2 into the inside of the outer skin portion 1 having the neck portion 1d and the opening portion 3 of the neck portion 1d, the filling material 4 is formed.
And a doll body is formed by injecting moisture and expanding the filler 4, and the head 5 is attached to the formed doll body.

The outer skin portion 1 is formed by injection molding with a stretchable material so that the body 1a, arm 1b, and leg 1c of the doll are seamlessly hollow and the neck 1d is opened. The outer skin portion 1 is formed by injection molding an elastomer (thermoplastic elastomer) exhibiting rubber elasticity at room temperature by using an upper and lower punch having an inner mold. The outer skin portion 1 is limited to an elastomer as long as it has elasticity. Instead of the thing, it may be silicon rubber.

As shown in FIG. 2, the skeletal portion 2 is made of a synthetic resin such as plastic, and is composed of a body member 10, a first skeletal member 11 simulating a humerus, and a second skeletal member 1 simulating a radius.
2, a third skeleton member 13 simulating a hand bone, a fourth skeleton member 14 simulating a hip bone, a fifth skeleton member 15 simulating a femur, and a connecting member 16 simulating a patella, It is composed of a sixth skeletal member 17 simulating the tibia and a seventh skeletal member 18 simulating the foot bone. The skeletal portion 2 is formed by connecting the respective parts in advance.

The filler 4 has a high fluidity when injected into the outer cover 1, and when the outer cover 1 is touched from the outside after the injection,
It is a material that feels a certain degree of hardness and easily flows when an external pressure is applied, and the outer skin portion 1 is easily deformed, and even if a small scratch is made on the outer skin portion 1 (for example, a needle is used). It is preferable that the filler 4 does not flow out of the wound, and a polymer absorber (absorbent polymer) is suitable as a material of the filler 4 satisfying these conditions. The absorbent polymer 4 absorbs water and expands. The absorbent polymer 4 that has absorbed water expands, and even if the outer skin portion 1 is damaged, it may not flow out of the outer skin portion 1 if it is a small wound. No,
This is because moisture does not come out even if pressure is applied. The filler is not limited to the absorbent polymer, but may be syrup.

Then, as shown in FIG. 3 (a), after the skeleton 2 is inserted while the opening 3 formed in the neck 1d of the outer skin 1 is expanded, an appropriate amount of moisture is absorbed in advance. Jelly-shaped absorbent polymer (hereinafter referred to as polymer)
4 is injected from the opening 3, and the inside of the outer skin 1 is filled with the polymer 4 (see FIG. 3B). When the filling is completed, a stopper 20 is placed in the opening 3 so that the polymer 4 does not leak, and the opening 4 is tied with a fastening member 21 such as a thread and fixed with an adhesive to close the neck (see FIG. 3C). A fine through-hole (not shown) penetrating vertically is formed in the plug 20, water is injected into the outer skin 1 through the through-hole, and moisture is absorbed by the polymer 4 so that no gap is formed in the outer skin 1. After that, the shaft 23a of the joint member 23 that joins the head 5 is inserted into the through-hole, and the opening 3 is completely closed so that the polymer 4 does not leak to form a doll body. The doll may be completed by joining the parts 5 together.

Before inserting the skeleton into the outer skin, it is preferable to inject a filler which has been made into a jelly form by absorbing water in advance into the polymer to the knee of the leg and the elbow of the arm. This is because, when the jelly-like polymer is injected after the skeleton is inserted, it is possible to avoid a trouble that the injection is not properly performed to the terminal.

In order to correct the shape of a specific part,
Moisture may be injected pinpoint with a tool such as a syringe with a fine needle. However, it is necessary that the shape of the hole formed by the needle tip is sufficiently smaller than the size of the polymer that has absorbed moisture.

The doll body manufactured as described above has a skeleton 2 inside an outer skin 1 made of a stretchable material.
Is arranged, and the inside of the outer skin portion 1 is filled with the filler 4. Therefore, when the outer skin portion 1 is flexible and touches the outer skin portion 1,
A natural feeling as if touching the human body can be obtained. Since the skeletal portion 2 has the respective skeletal members rotatably connected to each other, the skeletal member does not bend from a portion other than the connecting portion, and since the connecting portion is not visible from the outside, the knee and waist can be bent in a natural state. You can stretch it.

According to this doll body, as shown in FIG.
The doll body is formed of a seamless outer skin, and all connecting parts are not visible from the exterior, so that a sleeveless shirt 25 or mini skirt 26 with exposed shoulders, elbows and knees can be worn, and the waist is exposed. It is also possible to wear a swimsuit (not shown) to wear, and it is possible to realize a doll whose wearables are not limited.

Next, an arm skeleton portion corresponding to the arm portion of the skeleton portion is formed in advance with the outer skin portion, and a skeleton portion having no arm skeleton portion is formed.
A method of making a doll body by inserting it into the outer skin portion, connecting the arm skeleton portion formed on the outer skin portion and the skeleton portion, and then filling the filler is described.

First, as shown in FIG. 5, a flexible wire or the like is used as a core material 30 and a first protrusion having a fitting projection 31 at an end is provided at a predetermined distance from a humerus. Arm skeleton member 3
2, an arm skeleton part 35 composed of a second arm skeleton member 33 simulating a radius and a third arm skeleton member 34 simulating a hand bone is injection-molded with an olefin resin such as polypropylene. At this time, the boss 36 is formed so as to be connected to the third arm skeleton 34.

In the arm skeleton 35 formed by injection molding, the flexible core 30 is exposed at a portion corresponding to a joint such as a wrist or an elbow. It can be made, and the skeletal member is made of hard resin so as not to bend,
For example, there is no unnatural deformation such as bending in the middle of the upper arm.

Then, the fitting projection 31 of the arm skeleton 35 formed as described above is connected to the inner mold 40 of the outer skin molding die.
Into the fitting recess 41 formed in the shoulder of the inner mold 4
In a state where the arm skeleton 35 is connected to the portions corresponding to the two shoulders of 0, the inner die 40 is set to the outer die 42 with the arm skeleton 35 connected as shown in FIG. At this time, the boss 36 is fixed to the outer mold 42 so that the arm skeleton 35 does not move in the outer mold 42 during injection molding. And the inner mold 40
After the outer mold is covered from above, injection molding is performed by injecting the elastomer, the molded article is extracted together with the inner mold 40, and the inner mold 40 is further extracted from the molded article. Since the molded article is made of an elastic elastomer, the inner mold 40 can be easily pulled out while the neck portion is expanded. The molded product from which the inner mold 40 has been removed has a hollow body portion and leg portions, and the outer skin portion 1 is formed together with the arm portion including the arm skeleton portion 35 (see FIG. 7A). At this time, the boss 36 is separated.

Then, the parts constituting the skeleton member other than the arms are formed in advance, and the skeleton part 45 is assembled by assembling the parts. A fitting recess 48 for fitting the fitting projection 31 of the arm skeleton 35 is formed on a shoulder 47 pivotally supported by the body 46 of the skeleton 45.

Then, the assembled skeleton 45 is attached to the neck 1
d, while inserting the opening 3 while expanding it, and inserting the skeleton 45, the fitting recess 4 formed in the shoulder 47 of the skeleton 45.
8, the fitting projection 31 of the arm skeleton 35 is fitted, and the skeleton 4
5 and the arm skeleton 35 are connected (FIG. 7
(B)).

Then, the jelly-shaped polymer 4 may be injected from the opening 3 and the inside of the outer skin 1 may be filled with the polymer 4.

In the doll body constructed as described above, the skeleton 45 previously assembled does not have an arm portion.
When inserting into the outer skin part 1, it can be inserted smoothly. In addition, since the arm is formed together with the outer skin 1 in a state where the arm skeleton 35 is incorporated in advance, the skeleton is easily formed in the doll body by inserting the skeleton 45 and connecting with the arm skeleton 35. This makes it easy to insert a complicated skeleton from the opening in the neck, reduces the load on the opening in the outer skin, and prevents damage to the opening.

Next, a method of manufacturing a doll body in which wrinkles do not occur in the outer skin when a bent portion (for example, a knee portion) provided on a skeleton portion is bent will be described.

First, as shown in FIG. 8, a bent portion (for example, a knee portion) of the skeleton portion 2 including the fifth skeleton member 15, the connecting member 16, and the sixth skeleton member 17 is bent. The outer skin portion 1 is injection-molded so that the corresponding portion has a narrowed portion 50 narrower than the bent portion of the skeleton portion 2.

The skeleton 2 is inserted from the opening of the neck into the outer skin 1 having the constricted portion 50 formed in the same manner as the above-mentioned outer skin, and the knee of the skeleton 2 is connected to the outer skin 1. The constricted part 50 is inserted while being expanded.

When the doll body in which the skeleton is inserted into the outer skin portion by the above-described method is bent from the bent portion, the outer portion 50a of the constricted portion 50 of the outer skin portion 1 which has been expanded further expands, while the inner portion 50b extends. Since it acts in the shrinking direction, it shrinks, but does not generate wrinkles, and can eliminate unnatural deformation of the outer skin portion that occurs when bending. In addition, the above-mentioned constriction is not limited to the knee portion, and may be formed on the abdomen, for example. As a result, when the upper body is bent, no wrinkles are generated in front of the abdomen or on the left and right sides.

Next, another method of manufacturing a doll body in which a wrinkle does not occur in the outer skin portion when a bent portion (for example, a knee portion) provided on a skeleton portion is bent will be described.

This doll body has a bent portion of the skeleton (for example,
In order to prevent wrinkles from occurring in the outer skin portion when the knee portion is bent, the thickness of the outer skin portion corresponding to the bent portion of the skeletal portion (for example, the knee portion) is narrower than the bent portion of the skeletal portion. And is formed in a bent state in advance. As shown in FIG. 9, the outer skin portion 1 may be injection-molded using the inner mold 52 and the outer mold 53 in which the knee portion is bent in the bending direction in advance. According to the outer skin portion 1, when the knee is extended, the outer skin on the back side of the knee expands and the outer skin on the front side of the knee contracts. When the knee is bent, the outer skin on the rear side of the knee contracts and the outer side of the knee contracts. When the outer skin expands and the knee is extended, the outer skin on the front side of the knee contracts and the outer skin on the back side of the knee expands, so either the front or back of the knee does not unilaterally expand and contract, and the front and back are the same The doll body having a more natural bent portion can be provided.

As shown in FIG. 10A, a rib 55 may be formed to protrude from the inner surface of the buttocks of the outer skin 1. Due to this, when the doll body is bent from the waist part,
Without the rib 55, as shown in FIG. 10 (b), the entire buttocks bulge and the cracks in the buttocks also protrude. However, by providing the rib 55, as shown in FIG. 10 (c),
The outer skin portion can be deformed in a natural shape without protruding the crack portion. As described above, when the filler 4 moves to cause deformation in the outer skin portion 1, by providing a rib on the inner surface of a portion that is not desired to be deformed, occurrence of unnatural deformation can be suppressed, and more naturally. A deformable doll body can be formed.

[0038]

According to the first aspect of the present invention, since no seams are visible at the bent portion from the external appearance, a dress with exposed shoulders or a swimsuit with exposed waist can be worn, and the bent portion is covered with clothing. Since there is no need, there is no limitation on what can be put on the doll.

Further, since the skeleton portion is formed to bend from the bent portion, when the doll toy is deformed, it does not bend unnaturally such that a portion other than the portion to be bent does not bend. Dolls can be provided.

According to the second aspect of the present invention, when the skeleton portion is later inserted into the previously formed outer skin portion, the skeleton of the arm portion is formed together with the outer skin portion in advance, so that the skeleton portion can be moved from the arm portion to the arm portion. Since the skeleton of the portion can be removed, the skeleton can be easily inserted into the outer skin portion, the amount of expansion of the neck portion can be reduced, and the outer skin portion is not damaged at the time of expansion.

According to the third aspect of the present invention, the portion of the outer skin portion corresponding to the bent portion of the skeleton is made thinner than the bent portion.
When the skeletal part is inserted, the outer skin part will be stretched, and when the bent part is bent, the outer skin part inside the bent part will act to contract, preventing loosening and occurrence of extra wrinkles it can.

According to the fourth aspect of the present invention, when the knee is extended, the outer skin on the back of the knee expands and the outer skin on the knee contracts. When the knee is bent, the outer skin on the back of the knee contracts. Since the outer skin on the front side of the knee expands, either the front or back of the knee does not unilaterally expand or contract, so that a doll body having a more natural bent portion can be provided.

According to the fifth aspect of the present invention, when the doll is deformed, the filling material inside the doll does not move, and the portion not desired to be deformed does not bulge, so that the doll is formed in a natural shape. Can be deformed.

According to the sixth and seventh aspects of the present invention, since the outer skin is made of an elastomer, the skeleton can be inserted from the thin neck into the outer skin. Can be formed.

According to the eighth aspect of the present invention, since the filler is made of a polymer absorbent that expands by absorbing moisture, the filler does not flow out if the damage caused to the outer skin is small. According to the ninth aspect of the present invention, the feel when pressing the outer skin portion is good, and it is hard to flow out of the damaged portion generated in the outer skin portion.
