Description

The present invention relates to a doll body bending structure, a doll body using the same, and a method for manufacturing the doll body.

Conventionally, doll bodies of humans, animals, and various characters have a structure in which a skeletal member is incorporated into a covering member that represents the body shape of the doll body. For example, in this type of doll body, a doll body is known in which the joints of the arms and legs of the doll can be bent to take a posture similar to that of a human body, and the doll can maintain that bent posture (see, for example, Patent Document 1).

The doll body described in Patent Document 1 has a structure that mimics a skeleton with joints in the members that make up the arms or legs of a human body, and has intermediate joints that do not exist in the human body at positions different from the joints of the arms and legs of the human body, and these intermediate joints are used to bring the joints into contact with and away from each other, locking them at a specified angle and stopping and maintaining them.

JP 2006-122250 A

In Patent Document 1, in order to maintain the bending posture of the joints of the doll body, an intermediate joint that does not exist in the human body is used to maintain the bending angle of the joints. Because of this, there was a problem that the joints bend unnaturally because the structure is different from that of an actual human body.

In addition, in general, in doll bodies in which the skeletal members are covered with covering members, when the bending angle of the joints is deep (sharp bending), there is a problem that wrinkles occur on the inside of the bent parts of the joints and around them. In addition, when the covering member stretches on the outside of the bent parts, there is a problem that it becomes difficult to maintain the bent position (bending angle) of the bent parts of the joints due to the tension of the covering member.

The present invention aims to provide a doll body bending structure that can express more natural bending, a doll body using the same, and a method for manufacturing the doll body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A doll body and a bending structure for a doll body according to an embodiment of the present invention will now be described with reference to the drawings.
FIG. 1 is a front view of a doll body 1. FIG.
As shown in Fig. 1, the doll body 1 is a doll body imitating a human body with bulging muscles, for example, and has left and right arms 4L, 4R, left and right legs 5L, 5R, and a head 3 against a torso 2. As will be described later, this doll body 1 is configured such that an internal skeleton 11 (see Fig. 2) is covered with a covering 18. This doll body 1 is configured such that, for example, the elbow joints 4e of the left and right arms 4L, 4R and the knee joints 8 of the left and right legs 5L, 5R are bendable.

Fig. 2 is an enlarged view of the left arm 4L of the doll body 1 shown in Fig. 1. Fig. 3 is an enlarged view of the skeleton 11 of the left arm 4L.
2, the left arm 4L has an internal skeleton 11 that enables the elbow joint 4e to bend. The left arm 4L has a shoulder 6 attached to its upper end so that it can be attached to the torso 2, and a hand 7 attached to its lower end.
As shown in FIG. 3 , the skeleton 11 has two partial skeletons, an upper arm skeleton 13 and a forearm skeleton 14 , which are connected to each other by a bending portion 20 so as to be able to bend.

The three-dimensional shape (concave and convex shape) of the left arm 4L and skeleton 11 will be described below with reference to Figs. 4 to 9. Figs. 4 to 9 show the three-dimensional shape of the left arm 4L and skeleton 11 in side views from three directions: the left side, the inside (right side), and the rear of the doll body 1.

Figure 4(a) is a side view of the left arm 4L attached to the torso 2 as viewed from the left side, and Figure 4(b) is a side view of the skeletal part 11 of the left arm 4L as viewed from the left side. Figure 6(a) is a side view of the left arm 4L attached to the torso 2 as viewed from the inside (right side), and Figure 6(b) is a side view of the skeletal part 11 of the left arm 4L as viewed from the inside. Figure 8(a) is a side view of the left arm 4L attached to the torso 2 as viewed from the rear, and Figure 8(b) is a side view of the skeletal part 11 of the left arm 4L as viewed from the rear.

As shown in Figs. 4(a), 6(a) and 8(a), the outer surface 18us of the covering 18 of the left arm 4L has an uneven shape that imitates the shape of muscles. More specifically, for example, the upper arm 4u is formed so that the biceps 4ua and the triceps 4uc are appropriately bulged, and the forearm 4d is formed so that the forearm extensor group 4da and the forearm flexor group 4dc are formed. In addition, the wrist portion is formed with a supporter portion 30 that imitates a wrist supporter so as to surround the wrist.

As shown in Figs. 4(b), 6(b) and 8(b), the outer surface 11s of the skeleton 11 has an uneven shape that mimics the muscle shape of the outer surface 18us of the covering part 18. That is, the upper arm skeleton 13 corresponding to the upper arm 4u has a biceps corresponding convex part 13a and a triceps corresponding convex part 13c, and the forearm skeleton 14 corresponding to the forearm extensor group 4da has an extensor group corresponding convex part 14a and a flexor group corresponding convex part 14c. The wrist part has a supporter corresponding convex part 30a corresponding to the supporter part 30. The bending part 20 connecting the upper arm skeleton 13 and the forearm skeleton 14 has a bone-shaped part 23ws (described later) and a shape that mimics the elbow joint 4e.

Figure 5 is a partially cutaway side view showing the correspondence between the concave and convex shapes of the skeletal portion 11 and the covering portion 18 when viewed from the left side with the left arm portion 4L attached to the torso portion 2. Figure 7 is a partially cutaway side view showing the correspondence between the concave and convex shapes of the skeletal portion 11 and the covering portion 18 when viewed from the inside with the left arm portion 4L attached to the torso portion 2. Figure 9 is a partially cutaway side view showing the correspondence between the concave and convex shapes of the skeletal portion 11 and the covering portion 18 when viewed from the rear with the left arm portion 4L attached to the torso portion 2.

As shown in Figures 5, 7 and 9, the covering portion 18 is provided with its inner surface 18is in contact with almost the entire outer surface 11s of the skeletal portion 11. The thickness t1 of the covering portion 18 is provided to be approximately the same thickness, although it varies slightly depending on the part. In other words, the uneven shape of the outer surface 18us of the covering portion 18 is formed to correspond to the muscle shapes of the outer surface 11s of the skeletal portion 11 and the uneven shape of the support portion 30.

The skeleton 11 is made of synthetic resin or metal that has a certain degree of rigidity due to its structure. The covering 18 imitates human skin and is made of soft synthetic resin, synthetic rubber, or natural rubber. The covering 18 is not adhered to the skeleton 11 and is provided so as to be able to move relative to it. Therefore, the covering 18 can move in a displaced manner as it expands and contracts around the bending portion 20, and the covering 18 can be bent as the bending portion 20 of the skeleton 11 bends.

As described with reference to Figures 4 to 9, the upper arm skeleton 13 and the forearm skeleton 14 have a three-dimensional shape that roughly mimics the outer uneven shape of the doll body 1 by reducing the outer surface 11s, which has bulges corresponding to the external shapes of the muscles of the upper arm 4u and the forearm 4d. The external appearance of the bending portion 20 also has a three-dimensional shape with unevenness that mimics the shape of the elbow bone. Therefore, when the bending portion 20 is bent, the skeleton 11 and the covering portion 18 can move relative to each other, and the uneven shape can appropriately restrict the relative movement.

Fig. 10 is an exploded perspective view of the skeleton 11 of the left arm 4L. Fig. 11 is a perspective view of the bent portion 20 of the skeleton 11 shown in Fig. 10, viewed from the opposite direction.
As shown in FIG. 10, the left arm 4L has a structure in which two partial skeletons, an upper arm skeleton 13 and a forearm skeleton 14, are connected by a bending portion 20 having a plurality of connecting members corresponding to an elbow joint 4e.

The bending section 20 includes a first connecting member 21 that is connected to the upper arm skeleton 13, a second connecting member 22 that is connected to the forearm skeleton 14, and a third connecting member 23 that connects the upper arm skeleton 13 and the forearm skeleton 14.

The first connecting member 21 includes a pin portion 21p that is inserted into and connected to the joint-side recess 13h at one end of the upper arm skeleton 13, and a flat, approximately cylindrical rotating portion 21a that extends from one end of the pin portion 21p and includes a step portion 21d. More specifically, the rotating portion 21a includes a step portion 21d that protrudes in a direction perpendicular to the axis of the pin portion 21p and extends offset from the axis. The rotating portion 21a also includes a cylindrical hole 21h that opens in a direction perpendicular to the axis of the pin portion 21p.

The second connecting member 22 has a pin portion 22p that is inserted into the joint-side recess 14h at one end of the forearm skeleton 14, and a flat, approximately cylindrical rotating portion 22a that extends from one end of the pin portion 22p. A cylindrical hole 22h that opens in a direction perpendicular to the axis of the pin portion 22p is formed in the rotating portion 22a.

As shown in Figures 10 and 11, the third connecting member 23 includes a pair of support shafts 23b that fit into the cylindrical holes 21h of the first connecting member 21 and the cylindrical holes 22h of the second connecting member 22, a partition wall 23w that separates the pair of support shafts 23b, and a base plate 23a from which the support shafts 23b and the partition wall 23w protrude.

The base plate 23a is formed in a substantially circular shape so that the base of the pair of support shafts 23b corresponds to the shape of the rotating parts 21a, 22a of the first and second connecting members 21, 22. The partition wall 23w is provided with a bone-shaped part 23ws (see FIG. 11) that bulges outward in a rugged shape, for example, to imitate the bone shape of the elbow joint 4e of the human body.

In the bending portion 20 configured in this manner, the cylindrical holes 21h, 22h and the pair of support shafts 23b are fitted together with a suitable degree of frictional resistance to allow rotation. In other words, the bending portion 20 is configured to have a certain degree of hardness that allows the elbow joint 4e to bend and to maintain the bent state. In particular, when the elbow joint 4e is bent significantly, the bone-shaped portion 23ws can be made to appear to represent the outside of the elbow joint 4e.

A shoulder-side connector 13b protrudes from the other end of the upper arm skeleton 13 (upper side in FIG. 10) to connect to the shoulder 6. A hand-side connector 14b protrudes from the other end of the forearm skeleton 14 (lower side in FIG. 10) to connect to the hand 7.

FIG. 12 is a cross-sectional view of a main part with the covering portion 18 of the elbow joint 4e of the left arm 4L broken away.
In the elbow joint 4e, for example, as shown in FIG. 12, thin-walled portions 18c on the inside and outside of the elbow where the covering portion 18 covers the bending portion 20 are formed so that the thickness t2 on the inside of the elbow and the thickness t3 on the outside of the elbow are thinner than the thickness t1 of the other portions.

When the thickness of the covering portion 18 is configured to be thin in this way, for example, as shown by the imaginary line (dotted chain line) in Figure 12, when the elbow joint 4e is bent (bent in the direction of arrow R), the portion of thickness t2 on the inside of the elbow can bend inward easily without the covering portions 18 interfering with each other. Also, the thin thickness not only makes bending easy, but also prevents wrinkles from forming. On the other hand, the portion of thickness t3 on the outside of the elbow will stretch slightly, but the thin thickness allows the tensile force to be reduced.

A method for manufacturing the doll body 1 will now be described with reference to Figs. 13 and 14, taking the left arm 4L as an example.
Fig. 13 is a cross-sectional view of a main part of a molding die showing an example of a method for molding the doll body 1. Also, Fig. 14 is an exploded perspective view showing the assembly of the left arm 4L after the covering portion 18 has been molded.

The covering portion 18 is formed by injection molding using a molding die 50 .
The molding die 50 is configured by, for example, an upper die 51 and a lower die 52, and provides the outer concave and convex shape of the left arm 4L of the doll body 1 on an inner wall surface 50ws of a die space CS.
On the other hand, the skeleton 11 is configured to have a three-dimensional shape that is a reduced replica of the uneven shape of the outer surface of the left arm 4L as described above. Then, this skeleton 11 is placed and fixed in the mold space CS. That is, the skeleton 11 is placed so that, for example, the shoulder side connecting portion 13b and the hand side connecting portion 14b are located on the parting line PL. In this way, the three-dimensional shape of the outer surface 11s of the skeleton 11 corresponds to the uneven shape of the inner wall surface 50ws to form an injection space IS. The interval of this injection space IS becomes the thickness of the covering portion 18.

The soft coating resin 18m that constitutes the covering part 18 is injected from the injection gate 50g into the injection space IS thus formed. As a result, the covering part 18 is formed so as to conform to the shape of the outer surface 18us of the doll body 1 while adhering closely to the outer surface 11s of the skeleton part 11, which has a complex external shape.

After injection molding, the soft coating resin 18m is appropriately cooled and solidified to form the coating portion 18. This coating portion 18 is made of, for example, silicone rubber, and is separate from the outer surface 11s of the skeleton portion 11 without being integrated therewith.

The left arm 4L formed in this way is assembled by inserting and connecting the shoulder side connecting part 13b into the hole 6h of the shoulder 6 and the hand side connecting part 14b into the hole 7h of the hand 7, as shown in FIG. 14. The left arm 4L is assembled by attaching the shoulder 6 to the torso 2. The right arm 4R is manufactured and assembled in the same way. Both legs 5L, 5R can also be manufactured in the same way.

According to the bending structure of this embodiment, the skeleton 11 has a three-dimensional shape that roughly mimics the outer uneven shape of the doll body 1 by reducing it, and the covering 18 has an outer surface 18us that has an outer uneven shape and an inner surface 18is that has an inner uneven shape that contacts the outer surface 11s of the skeleton 11. Therefore, when the bending portion 20 is bent, the uneven shape improves the unity of the skeleton 11 and the covering 18, and the elasticity of the covering 18 can prevent the covering 18 and the bending portion 20 from returning, and the covering 18 can easily follow the bending of the skeleton 11 while maintaining the shape of the outer surface 18us. In addition, the covering 18 that covers the bending portion 20 can be prevented from wrinkling or shrinking, allowing the bending portion 20 to be naturally curved.

In addition, in the bending structure of this embodiment, the covering portion 18 is arranged to allow misalignment with respect to the outer surface 11s of the skeletal portion 11 while in contact with the outer surface 11s, so that when the bending portion 20 is bent, wrinkles and shrinkage due to misalignment of the covering portion 18 with respect to the outer surface 11s of the skeletal portion 11 can be suppressed. As a result, the covering portion 18 can easily follow the bending of the skeletal portion 11 while maintaining the shape of its outer surface 18us, and a natural bending of the bending portion 20 can be expressed.

In addition, in the bending structure of this embodiment, the doll body 1 has a shape that imitates the human body, and the skeletal section 11 has two partial skeletal sections (upper arm skeletal section 13 and forearm skeletal section 14) whose outer surface is uneven and imitates the shape of muscles, and a bending section 20 that connects these two partial skeletal sections so that they can be bent, and the covering section 18 is provided with a thickness that covers the skeletal section 11 almost uniformly, so that the bending section 20, which corresponds to the joint, can be made to have a slightly narrower appearance compared to the muscle bulge. As a result, the occurrence of wrinkles and shrinkage of the covering section 18 at the bending section 20 can be suppressed, and the bending of the joints of the human body can be naturally expressed.

In addition, in the bending structure of this embodiment, the thickness of the covering part 18 at the portion covering the bending part 20 is thinner than the thickness of the other portions, so that the occurrence of wrinkles and abrasions of the covering part 18 at the bending part 20 can be more effectively suppressed, and the bending of the joint of the human body can be more naturally expressed.

In addition, in the bending structure of this embodiment, the multiple connecting members include a first connecting member 21 that is connected to the upper arm skeleton 13, a second connecting member 22 that is connected to the forearm skeleton 14, and a third connecting member 23 that rotatably supports the first connecting member 21 and the second connecting member 22 and connects the first connecting member 21 and the second connecting member 22. In addition, the third connecting member 23 has a bone-shaped portion 23ws that mimics the elbow of the elbow joint 4e, so that when the elbow joint 4e is bent, the elbow can be naturally flexed.

In addition, the bending structure of the doll body 1 is such that the skeleton 11 has a three-dimensional shape that reduces the outer uneven shape of the doll body 1, the outer surface 18us of the covering 18 has an outer uneven shape, and the inner surface 18is has an inner uneven shape that contacts the outer surface 11s of the skeleton 11, so that when the bending portion 20 is bent, the covering 18 can easily follow the bending of the skeleton 11 while maintaining the shape of the outer surface. As a result, it is possible to provide a doll body 1 that can naturally express bending when the bending portion 20 of the doll body 1 is bent.

In addition, the manufacturing method of the doll body 1 of this embodiment includes a process in which the uneven outer surface shape of the doll body 1 is made the same as the inner wall surface shape of the mold space CS for molding, a three-dimensional skeleton 11 that is a reduced replica of the uneven outer surface shape is placed in the mold space CS, and soft coating resin 18m that constitutes the covering 18 is injected into an injection space IS that is formed by matching the three-dimensional shape of the skeleton 11 with the uneven inner wall shape. Therefore, even if the uneven outer surface shape of the doll body 1 is complex, a covering 18 of the desired thickness that corresponds to the skeleton 11 can be easily provided.

In addition, in the manufacturing method of the doll body 1 of this embodiment, the soft coating resin 18m separates from the outer surface 11s of the skeleton 11 after injection molding, so when the bending portion 20 is bent, the position of the coating 18 can be shifted relative to the outer surface 11s of the skeleton 11. As a result, the coating 18 can easily follow the bending of the skeleton 11 while maintaining the shape of the outer surface 18us.

Although one embodiment of the present invention has been described above, the present invention can be modified as appropriate within the scope of its technical concept. For example, in the above embodiment, a human-shaped doll body 1 has been described, but the doll body 1 of the present invention is not limited to a human body shape and may also be modeled after an animal or a specific character.

In the above embodiment, the bending portion 20 is described as the elbow joint 4e, but it can also be applied to, for example, the wrist, shoulder joint, knee joint, hip joint, ankle, etc. It can also be applied to parts that bend to a certain extent, such as the spine and neck.

In the above embodiment, the outer surface irregular shape of the doll body 1 is mainly described as imitating the shape of muscles, but the outer surface irregular shape is not limited to this, and may also imitate the shape of clothing when the doll body 1 is wearing clothing.
