[0014]

BEST MODE FOR CARRYING OUT THE INVENTION In FIG. 1, reference numeral A indicates a doll A formed by the method for manufacturing a doll body according to the present invention, and the doll A is a body portion 1a and arms formed of a stretchable material. The pre-assembled skeleton portion 2 is inserted into the outer skin portion 1 having the neck portion 1d having the opening portion 1b and the leg portion 1c while the neck portion 1d is opened while the opening portion 3 of the neck portion 1d is being expanded, and then the filling material 4 is inserted.
The doll body is formed by a method in which the doll body is filled with, and water is further injected to expand the filling material 4, and the head portion 5 is attached to the formed doll body.

The outer skin portion 1 is formed of a stretchable material by injection molding and forms the body portion 1a, the arm portion 1b and the leg portion 1c of the doll so that the neck portion 1d is open in a seamless hollow. The outer skin portion 1 is formed by injection molding an elastomer (thermoplastic elastomer) that exhibits rubber elasticity at room temperature by vertical punching with an internal mold. The outer skin portion 1 is limited to an elastomer as long as it has elasticity. Silicon rubber may be used instead of the one.

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

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

Then, as shown in FIG. 3 (a), after inserting the skeleton portion 2 while expanding the opening 3 formed in the neck portion 1d of the outer skin portion 1, an appropriate amount of water is absorbed in advance. Jelly-shaped absorbent polymer (hereinafter referred to as polymer)
4 is injected through the opening 3 to fill the inside of the outer skin 1 with the polymer 4 (see FIG. 3B). When the filling is completed, a stopper 20 is attached to the opening 3 so as to prevent the polymer 4 from leaking, and the neck 4 is closed by binding with a fastening member 21 such as a thread and fixing with an adhesive (see FIG. 3C). A thin through hole (not shown) is formed in the stopper 20 so as to vertically penetrate therethrough, and water is injected into the outer skin portion 1 through the through hole, and the polymer 4 absorbs the water so that no gap is formed in the outer skin portion 1. After that, the shaft body 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.

Before the skeleton is inserted into the outer skin, it is preferable to inject a jelly-like filler in which the polymer has absorbed water to the knees of the legs and the elbows of the arms. This is because, when the jelly-like polymer is injected after the skeleton is inserted, it is possible to avoid the trouble of not being able to inject well to the end.

Further, in order to correct the shape of a specific part,
Water may be injected pinpoint with a tool such as a syringe with a thin needle tip. However, the shape of the hole formed by the needle tip must be sufficiently smaller than the size of the polymer that has absorbed water.

The doll body manufactured as described above has a skeleton portion 2 inside an outer skin portion 1 formed of a stretchable material.
Are arranged and the inside of the outer skin portion 1 is filled with the filler 4, so that when the outer skin portion 1 is touched, there is flexibility.
You can get a natural feeling as if you were touching the human body. Since the skeleton member 2 is rotatably connected to each other, the skeleton member does not bend from a portion other than the connecting portion, and the connecting portion cannot be seen from the outside. You can stretch.

According to this doll body, as shown in FIG.
Since the doll body is made of a seamless outer skin and you cannot see all the connecting parts from the outside, you can wear a sleeveless shirt 25 or miniskirt 26 with exposed shoulders, elbows and knees, and the waist is exposed. A swimsuit (not shown) that wears can also be put on, and it is possible to realize a doll whose clothes are not limited.

Next, an arm skeleton corresponding to the arm of the skeleton is molded together with the outer skin in advance, and a skeleton without an arm skeleton is
A method of making a doll body by inserting it into the outer skin portion, connecting the arm skeleton portion and the skeleton portion formed in the outer skin portion, and then filling the same with a filling material will be described.

First, as shown in FIG. 5, a flexible wire or the like is used as a core material 30 and a fitting protrusion 31 is provided at an end thereof at a predetermined interval to imitate a humerus bone. Arm skeleton member 3
2, an arm skeleton portion 35 including 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 portion 34.

In the arm skeleton portion 35 formed by injection molding, since the flexible core material 30 is exposed at the parts corresponding to the joints such as the wrist and elbow, the core material 30 may be bent. Moreover, since the skeletal member is made of hard resin to prevent it from bending,
For example, there is no unnatural deformation such as bending from the middle of the upper arm.

Then, the fitting protrusion 31 of the arm skeleton portion 35 formed as described above is provided with the inner die 40 of the outer skin molding die.
It is fitted into the fitting recess 41 formed on the shoulder of the inner mold 4
The arm skeleton part 35 is connected to the parts corresponding to both shoulders of 0, and the inner mold 40 is set to the outer mold 42 as shown in FIG. 6 with the arm skeleton part 35 being connected. At this time, the boss 36 is fixed to the outer mold 42 so that the arm skeleton portion 35 does not move inside 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 an elastomer, the molded product is extracted together with the inner mold 40, and the inner mold 40 is further extracted from the molded product. Since the molded product is made of a stretchable elastomer, the inner mold 40 can be easily removed while expanding the neck portion. The molded product obtained by removing the inner mold 40 has a hollow body and legs, and the outer skin 1 is formed together with the arm including the arm skeleton 35 (see FIG. 7A). At this time, the boss 36 is separated.

Then, the parts constituting the skeleton member other than the arms are preformed, 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 in a shoulder 47 rotatably supported by a body 46 of the skeleton 45.

Then, the assembled skeleton portion 45 is attached to the neck portion 1
The insertion recess 4 formed in the shoulder 47 of the skeleton portion 45 is inserted after expanding the opening 3 of d and inserting the skeleton portion 45.
8 is fitted with the fitting projection 31 of the arm skeleton portion 35, and the skeleton portion 4
5 and the arm skeleton portion 35 are connected (see FIG. 7).
(See (b)).

The jelly-like polymer 4 may be injected from the opening 3 to fill the inside of the outer skin 1 with the polymer 4.

In the doll body constructed as described above, since the skeleton portion 45 assembled in advance has no arms,
When inserting into the outer skin part 1, it can be smoothly inserted. Moreover, since the arm portion is formed together with the outer skin portion 1 in a state where the arm skeleton portion 35 is incorporated in advance, the skeleton portion can be easily formed in the doll body by inserting the skeleton portion 45 and then connecting with the arm skeleton portion 35. Therefore, it is possible to facilitate the work of inserting the complicated skeleton portion through the opening portion of the neck portion, reduce the load applied to the opening portion of the outer skin portion, and prevent the opening portion from being damaged.

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

First, as shown in FIG. 8, the bending portion (for example, the 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 to a bent portion. The outer skin portion 1 is injection-molded so that a corresponding portion has a narrowed portion 50 thinner than the bent portion of the skeleton portion 2.

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

In the doll body in which the skeleton portion is inserted into the outer skin portion by the above-described method, the outer side 50a of the narrowed portion 50 of the outer skin portion 1 which has been stretched further extends when bent from the bent portion, but the inner side 50b is Since it acts in the direction of contraction, it may contract, but it does not cause wrinkling of wrinkles, and it is possible to eliminate unnatural deformation of the outer skin portion that occurs when it is bent. The narrowed portion is not limited to the knee portion and may be formed in the abdomen, for example. As a result, when the upper body is bent, wrinkles do not occur near the front or left and right of the abdomen.

Then, another method of manufacturing a doll body in which wrinkles do not occur in the outer skin portion when the bending portion (eg, knee portion) provided in the skeleton portion is bent will be described.

This doll body has a bent portion (for example,
In order to prevent wrinkles from occurring in the outer skin when the knee is bent, the thickness of the outer skin at the portion corresponding to the bent portion of the skeleton (for example, the knee) is narrower than the bent portion of the skeleton. Is formed, and is formed in a bent state in advance. For this, 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 knees are 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 stretches and the outer skin on the front side of the knee contracts, and when the knee is bent, the outer skin on the back side of the knee contracts and the outer skin on the front side of the knee contracts. When the outer skin stretches and the knee is stretched, the outer skin on the front side of the knee contracts and the outer skin on the back side of the knee expands.Therefore, either side of the knee does not expand or contract unilaterally. Since it expands and contracts, it is possible to provide a doll body having a more natural bent portion.

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

[0038]

According to the first aspect of the present invention, since the joints are not visible in the bent portion from the outside, a dress with exposed shoulders, a swimsuit with exposed waists, etc. can be worn, and the bent portion is covered with clothes. There is no need to limit what you can wear on the doll.

Further, since the skeleton portion is formed so as to be bent from the bent portion, when the doll toy is deformed, there is no unnatural bending such that the portion other than the portion to be bent is bent, so that it is more natural. We can provide dolls.

According to the second aspect of the present invention, when the skeleton portion is inserted into the preformed outer skin portion later, the skeleton of the arm portion is formed together with the outer skin portion in advance, so that the skeleton portion is changed to the arm portion. Since the skeleton of the part can be removed, the skeleton part can be easily inserted into the outer skin part, the expansion amount of the neck part can be small, and the outer skin part is not damaged during the expansion.

According to the third aspect of the present invention, the outer skin portion corresponding to the bent portion of the skeleton is made thinner than the bent portion.
When inserting the skeleton, the outer skin will be stretched, and when the bent part is bent, the outer skin part inside the bent part will contract so that slack and excess wrinkles can be prevented. it can.

According to the invention of claim 4, 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, and when the knee is bent, the outer skin on the back side of the knee contracts. Since the outer skin of the front side of the knee stretches, either the front side or the back side of the knee does not expand or contract unilaterally, so that it is possible to provide a doll body having a more natural bending portion.

According to the fifth aspect of the present invention, when the doll body is deformed, the filling material inside the doll body does not move and the deformable part does not bulge out. It can be transformed with.

According to the sixth and seventh aspects of the present invention, by making the outer skin part an elastomer, the skeleton part can be inserted into the outer skin part from a thin neck, so that there is no seam in the outer skin part and the doll body is in a natural state. Can be formed.

According to the eighth aspect of the present invention, the filler is made to be a polymer absorber that absorbs water and expands, so that the filler does not flow out if damage to the outer skin is small. According to the ninth aspect of the present invention, the feeling when the outer skin portion is pushed is good, and moreover, it is difficult for the damaged portion generated in the outer skin portion to flow out.
