Moreover, what is called what is called a doll's element | base_body and the head can be connected is also included. Further, all of the so-called movable dolls and the dolls whose limbs, hips, etc. do not move, which are configured so that the required parts such as the limbs, the waist can be moved are also targeted. The movable doll includes all known ones such as those separately provided with joint portions at required movable portions and those integrally formed without any joint portions.
Further, the material constituting the doll may be hard or soft, and the design can be changed within the scope of the present invention.

In the recent doll industry, dolls having a configuration that faithfully replicates the human body (naked body) form called a figure are gaining popularity among customers.
The figure dolls are usually played by girls and the like, or simply dressed up, but the figure consumer base has changed recently, especially for male and female adults. Is also increasing. In such an adult consumer group, there are many cases where doll parts are exchanged according to the hobbies of each consumer. In particular, doll heads have a wide variety of facial expressions and hairstyles, and there are many customers who want to choose their favorite facial expressions and hairstyle heads and combine them with their dolls.

Therefore, the present inventor has previously provided a connection structure of the head and the neck as disclosed in Patent Document 1 in order to meet such consumer needs.
The connecting structure of the head and neck disclosed in Patent Document 1 is a cylindrical neck skin mounting portion (neck body main body) that is fitted and fitted into a neck skin formed integrally with the body skin constituting the body of the doll. ) And a large diameter compared with a circular connecting hole provided in the upper skin of the doll at the upper end of the neck body so as to be swingable (extendable / contractible) in the vertical direction via an elastic member. It is comprised by the substantially conical head outer skin fitting part (locking part) which has a lower end circular surface. And as for the said elastic member, the latching part has mentioned the coil spring which always pulls and acts on the upper end direction of a neck part main body as an example.
That is, when the connecting hole of the head skin is expanded and the engaging part is inserted, the lower end circular surface comes into contact with the inner peripheral edge of the connecting hole, and the engaging part is moved toward the upper end of the neck body by the elastic member. The neck portion is connected to the head portion (head skin) by holding the inner and outer peripheral edges of the connection hole between the lower end circular surface and the upper end surface of the neck body. Further, the locking state of the locking portion to the connection hole is released, and the connection between the head and the neck is released.
Thereby, the consumer can make the doll according to a consumer's liking by changing the head with a different facial expression according to liking each time.

Also, in recent years, a way to play with a doll, wearing a head of your choice, creating an original doll called a custom doll with various outfits, and then posing the doll and publishing the photographed image. Is being recognized.
For enthusiasts who like to play like that, the atmosphere created by the dolls that have been subjected to posing is a particularly important factor. There is a tendency to want posing.

In this case, in the joint structure of the head and neck disclosed in Patent Document 1, the head can only rotate in the horizontal direction with respect to the neck. For example, the head is depressed to express anxiety, I couldn't make a pose that expressed emotions such as looking up and expressing sweetness.

  As shown in FIGS. 1 to 9, the neck portion 2 is composed of a head shaft portion 3 connected to the head portion 1 and a neck portion body 4 fixed to a trunk (not shown). Further, the head shaft portion 3 and the neck portion main body 4 are connected by a sliding structure that can swing in an arbitrary direction with a predetermined center.

The head shaft portion 3 is composed of a shaft body 31 and an elastic connection structure.
As shown in FIG. 3, the shaft body 31 includes a rod-shaped member 32 formed in a rod shape having a predetermined length, a seat surface portion 34 provided on the upper end 32 a side of the rod-shaped member 32, and a lower end 32 b side of the rod-shaped member 32. The sliding head 36 is provided, and the elastic coupling mechanism is disposed between the seat surface portion 34 and the sliding head 36.
The seat surface portion 34 is made of, for example, a synthetic resin material in the present embodiment, and is formed in a disk shape having a diameter that can be inserted into the round hole 12 of the neck connection hole 11 of the head portion 1, and one end surface (upper surface) side thereof. Is integrally provided with a tapered portion 34a.
The rod-shaped member 32 is formed in an oval shape with a cross-sectional shape from a substantially middle portion in the length direction to the lower end 32b. Specifically, it is formed in a shape in which a pair of opposing long sides of the parallel plane 32c and the plane 32d are continuously connected by an arc surface.
A screw hole 35 is provided at the lower end 32 b of the rod-shaped member 32 toward the seat surface portion 34. Note that the length of the shaft body 31 may be formed such that the upper end 32 a side including the seat surface portion 34 can be connected by being inserted into the head 1 from the neck connection hole 11. Therefore, the length of the shaft body 31 is not particularly limited here.

A sliding head 36 is provided at the lower end 32 b of the shaft body 31 of the rod-shaped member 32.
The sliding head 36 has a so-called bead shape in which a parallel plane is formed on each of the upper end 38a and the lower end 38b, and an outer peripheral surface 38 connecting the upper end 38a and the lower end 38b is formed in a spherical shape.
The upper end 38a is provided with a bonding hole 37a in the direction of the lower end 38b, and the lower end 38b is provided with a screw accommodation hole 37b.
The joint hole 37 a is formed in a similar shape slightly larger than the oval cross-sectional shape of the rod-shaped member 32. Thereby, when the lower end 32b side of the rod-shaped member 32 is bonded to the bonding hole 37a, the pair of planes of the bonding hole 37a and the pair of planes of the rod-shaped member 32 are fitted to slide with respect to the rod-shaped member 32. The head 36 is prevented from rotating in the circumferential direction.

Furthermore, the bottom surfaces of the joint hole 37a and the screw accommodation hole 37b are connected by a communication hole 37c, and the axes of the joint hole 37a, the communication hole 37c, and the screw accommodation hole 37b are aligned with the axis of the sliding head 37. Shaped to share.
A lower end 32b of the shaft main body 31 is inserted into the joint hole 37a, and a screw S is inserted into the screw receiving hole 37b. The screw S is screw-coupled to the screw hole 35 of the shaft main body 31 through the communication hole 37c. Is done. Thereby, the head axis | shaft part 3 and the sliding head 36 are fixed integrally.

  As shown in FIGS. 4 and 5, the elastic coupling mechanism is inserted through the shaft main body so as to be movable in the axial direction, and is capable of contacting the inner peripheral edge of the neck coupling hole, and the seat surface portion 34. The elastic member 7 is incorporated between the contact members 5 and constantly urges the contact member 5 in the direction of the neck connecting hole 11.

The contact member 5 includes a through hole that communicates the opening 52a of the upper end 51a and the opening 52b of the lower end 51b, and has an outer diameter larger than the diameter of the round hole 12 of the neck connecting hole 11 of the head 1. It has a substantially cylindrical shape.
The opening 52a of the upper end 51a is dug to a predetermined depth to form an elastic member accommodation hole 55a.

The opening 52b of the lower end 51b is formed in a similar shape slightly larger than the cross-sectional shape formed in the oval shape of the rod-like member 32 of the shaft body 31, and to the bottom surface 53c of the elastic member accommodation hole 55a. A central hole 55b is formed by being penetrated and dug. In this case, the opening 52a is formed larger than the opening 52b.
The upper end 51a side of the outer peripheral surface 56 of the contact member 5 forms a tapered shape 56a that is narrowed down to a small diameter.
The abutting member 5 slides on the seat surface portion 34 of the shaft main body 31 by inserting the rod-shaped member 32 of the shaft main body 31 into the opening 52a (elastic member receiving hole 55a) and the opening 52b (center hole 55b). Between the head 36, the abutment member 5 is assembled so that the upper end 51 a side faces the seat surface 34.
At this time, when the rod-shaped member 32 is brought into communication with the opening 52b (center hole 55b), the pair of planes of the opening 52b (center hole 55b) and the pair of planes of the rod-shaped member 32 are fitted to the rod-shaped member 32. On the other hand, the contact member 5 is prevented from rotating in the circumferential direction.

Furthermore, the surface of the lower end 51b is provided with grooves 53a and 53b formed in parallel at a predetermined interval. Accordingly, the edge of the lower end 51b is divided into edges 54a and 54b formed outside the grooves 53a and 53b and edges 54c and 54d formed between the grooves 53a and 53b.
Since the outer diameter of the contact member is formed larger than the diameter of the round hole 12 of the neck connecting hole 11 of the head 1, the edges 54 a, 54 b, 54 c, 54 d are connected to the neck connecting hole of the neck 2. 11 can be brought into contact with the inner peripheral edge.

In this embodiment, the elastic member 7 employs a coil spring 7 as an example. Specifically, the coil spring 7 is wound around the outer periphery of the rod-shaped member 32 and has a smaller diameter than the diameter of the opening 52 a of the upper end 51 a of the contact member 5.
The upper end 7 a of the coil spring 7 abuts on the seat surface portion 34, and the lower end 7 b side of the coil spring 7 is accommodated in the opening 52 a of the abutting member 5, so that the coil spring 7 is incorporated between the seat surface portion 34 and the abutting member 5. It is. Thus, the upper end 7 a of the coil spring 7 is supported by the seat surface portion 34, so that the lower end 7 b always biases the contact member 5 toward the neck connecting hole 11.

In this embodiment, the coil spring 7 is incorporated between the seat surface portion 34 and the contact member 5 so that the contact member 5 is always urged toward the neck connecting hole 11. For example, the upper end 7 a of the elastic member 7 may be directly fixed to the upper end 32 a of the rod-shaped member 32. In such a configuration, the shaft main body 31 may not include the seat surface portion 34.
Further, the elastic member 7 does not have to be a coil spring as long as it can always urge the contact member 5 in the direction of the neck connecting hole 11. An example is a rubber-like body.

The neck main body 4 is made of, for example, a hard synthetic resin material in the present embodiment, and can be fitted and fixed to a body (not shown) as shown in FIG. 6 and has a diameter larger than the sphere diameter than the sliding head 36. The cylinder part 43 which has an internal diameter, and the slide receiving part 42 distribute | arranged to the upper end 4a side of this cylinder part 43 are provided.
The slide receiving portion 42 is provided with a curved shape by narrowing the inner peripheral surface of the cylindrical portion 43 so as to gradually become a small diameter toward the opening 41 toward the center of the opening, and the curved inner peripheral surface slides. The receiving part 42 is comprised. Thereby, the upper end 4 a of the neck body 4 is formed with an opening 41 having a smaller diameter than the spherical diameter of the sliding head 36.
Furthermore, a flange 46 is provided on the upper end 4 a side of the outer peripheral surface of the cylindrical portion 43.
The flange 46 protrudes in the horizontal direction and is continuously curved in the circumferential direction, and curves toward the opening 41 of the upper end 4a from the flange surface 46a so as to gradually become a small diameter in the center direction of the opening 41. It is composed of an upwardly inclined tapered shape 46b.
When the neck main body 4 is fitted into a cylindrical neck skin that is integrally extended from a soft vinyl resin body part (not shown), the collar 46a has an edge of the neck skin on the collar 46a. Abut.

  In the figure, reference numeral 47 denotes a plurality of dropout prevention portions provided in a predetermined outer peripheral region of the neck body 4. In this embodiment, the protrusions that are continuous in the circumferential direction are provided at predetermined intervals in the axial direction of the neck body 4. A plurality of protrusions are provided. The drop-off prevention part 47 has a structure for preventing the drop-off when the neck part 2 is fitted into a cylindrical neck part skin integrally extending from a soft vinyl resin body part (not shown). Therefore, it is not limited to the structure of the present embodiment, and any structure that can prevent the neck portion 2 from falling is within the scope of the present invention. In addition, the form which is not provided with this drop-off prevention part 47 is also within the scope of the present invention. In the present embodiment, the neck body 4 is formed in a cylindrical shape, but is not particularly limited, and the design can be changed within the scope of the present invention, such as a rectangular tube shape.

The sliding structure includes a sliding head 36 of the head shaft portion 3 and a sliding receiving portion 45 of the neck body 4. In this case, the outer peripheral surface 38 formed in a spherical shape of the sliding head 36 and the sliding receiving portion 45 are connected in sliding contact. As a result, the head shaft 3 can swing in any direction with respect to the neck body 4 with the center of the sliding head 36 as the center of swing.
The outer peripheral surface 38 formed in the spherical shape of the sliding head 36 and the sliding receiving portion 45 may be formed so that at least the respective sliding ranges are formed in a spherical shape.
Further, the sliding structure may have another configuration as long as the sliding head 36 and the neck main body 4 fixed to the trunk are connected to be swingable in an arbitrary direction with a predetermined center. .
For example, the neck body 4 may be provided with the sliding head 36, and the head shaft portion 3 may be provided with the sliding receiving portion 45 that can be brought into sliding contact with the sliding head 36.

When assembling the neck portion 2 composed of the above components, the lower end 7b side of the coil spring (elastic member 7) is accommodated in the elastic member accommodating hole 55a of the abutting member 5, and the coil spring 7 and the abutting member 5 are accommodated. Is fitted from the lower end 32b of the rod-shaped member 32 of the head shaft portion 3.
Next, from the opening 41 of the upper end 4 a of the neck body 4, the lower end 32 b of the rod-shaped member 32 of the head shaft portion 3 is inserted, and the sliding head 36 is inserted from the lower end of the tube portion 43 of the neck body 4. The lower end 32 b of the rod-like member 32 is fitted into the joint hole 37 a of the upper end 38 a of the sliding head 36.
Further, the screw 2 is inserted into the screw receiving hole 37b of the rod-like member 32 from the lower end of the cylindrical portion 43 of the neck main body 4, and is screwed to the screw hole 35 of the shaft main body 31 through the communication hole 37c, thereby the neck 2 Is completed (see FIG. 7).

  Here, the connection operation | movement and connection release operation | movement of the head 1 and the neck part 2 by the head connection structure of a present Example are demonstrated based on FIG.8, FIG.9 and FIG.1.

First, the operation | movement which connects the head 1 and the neck 2 is demonstrated.
The neck part 2 is inserted into the round hole 12 of the neck part connection hole 11 of the head part 1 from the head shaft part 3 side (FIG. 8). At this time, by warming the neck connection hole 11 of the head 1 with warm air or the like, the material around the neck connection hole 11 becomes soft, so that it is easy to insert.
At this time, since the hole diameter of the round hole 12 is smaller than the outer diameter of the contact member 5, the tapered surface 54a of the contact member 5 causes the round hole 12 to be inward of the head (upward in the figure). While being pressed, it penetrates into the inside of the head and pushes the round hole 12 in accordance with the penetration. Thereby, the head axis | shaft part 3 and the contact member 5 can penetrate | invade in a head.
When the head shaft portion 3 and the contact member 5 continue to enter the head portion, the step portion 15 of the round hole 12 is caught by the edges 54a, 54b, 54c, 54d of the lower end 51b of the contact member 5 (see FIG. 9).

Next, when the neck portion 2 is slightly pulled outward (downward in the drawing), as shown in FIG. 1, the edge portions 54a, 54b, 54c of the lower end 51b of the contact member 5 caught on the step portion 15 are obtained. 54 d pushes up the contact member 5, and a gap is formed between the lower end 51 b of the contact member 5 and the upper end 4 a of the neck body 4, and the round hole 12 that is pushed and expanded is fitted into the gap.
At this time, the abutting member 5 is positioned so as to fit within the edge portion 14 and is pressed toward the neck connecting hole 11 (downward in the figure) by the urging force of the coil spring 7. The step portion 15 and the edge portions 54a, 54b, 54c, and 54d are in close contact with each other.

In addition, on the outer surface side of the neck connecting hole 11 of the head 1, a mortar-shaped inclined surface 13 formed on the outer peripheral edge is in contact with the rising inclined taper 46 a of the neck body 4. At this time, the mortar-shaped inclined surface 13 is pressed against and closely contacts the tapered shape 46 b of the neck body 4 through the contact member 5 pressed toward the neck connecting hole 11 by the biasing force of the coil spring 7. . Thereby, the neck 2 and the head 1 are integrally connected.
When the connection between the head 1 and the neck 2 is released, the neck 2 may be pulled out strongly toward the outside of the head (downward in the figure). At this time, by warming the neck connection hole 11 of the head 1 with warm air or the like, the material around the neck connection hole 11 becomes soft, so that it is easy to pull out.

As described above, the head connecting structure according to this embodiment not only facilitates the detachment of the head 1 with respect to the neck 2 but also the sliding structure connecting the head shaft 3 and the neck body 4. In addition to the operation by the conventional head connection structure, the operation which is impossible with the conventional head connection structure is possible. In the following, the operation made possible by this embodiment will be described.
In the sliding contact structure, the outer peripheral surface 38 formed in the spherical shape of the head shaft portion 3 is always pressed against the sliding receiving portion 45 of the neck body 4 by the elastic force of the elastic member 7 and is in sliding contact. The head shaft portion 3 can be arbitrarily swung in all directions with respect to the neck portion main body 4 within a range in which the rod-like member 32 does not contact the opening 41 while maintaining appropriate friction (see FIG. 10).

In this case, the rocking center is the center of the head shaft portion 3. Of course, the head shaft portion 3 can be rotated in the horizontal direction with respect to the neck portion main body 4 as in the prior art. By combining such movements, the head 1 is tilted laterally with respect to the neck main body 4 (cross section between both ears of the head, see FIG. 11), or the face is tilted downward and close. Or the like (see FIG. 12). Thereby, posing that expresses rich emotions becomes possible.
In addition, when the head 1 and the neck 2 are connected, the head shaft 3 serving as the center of swinging is arranged directly below the head 1, so that the head is located at the base of the head like an actual human. The state of swinging the part has been reproduced, and it has become possible to perform poses that allow you to taste deep emotional empathy closer to a real person.

At this time, the rod-shaped member 32 is inserted through the contact member 5 so as not to idle, and the lower end 32b of the rod-shaped member 32 is connected to the sliding head 36 so as not to idle. The contact member 5 and the sliding head 36 are prevented from rotating in the circumferential direction. Therefore, the head 1 rotates only by the sliding structure.
As a result, the head 1 is prevented from unintentionally rotating by appropriate friction between the sliding head 36 and the sliding receiving portion 45, and the orientation of the head 1 during posing is firmly held. Moreover, since the sliding head 36 does not idle with respect to the rod-shaped member 32 by the said structure, the screw S which fixes the sliding head 36 and the rod-shaped member 32 is also prevented from loosening.

In the above-described embodiment, the rod-shaped member 32, the joint hole 37a of the sliding head 36, and the opening 52b (center hole 55b) of the contact member 5 are formed in an oval shape, and the surface of the oval shape is formed. The above-mentioned members prevent the members from spinning around each other, but they can be formed in other shapes as well as the oval shape as long as they can be prevented. For example, the cross-sectional shape may be a star shape or a D shape. Or when it is not necessary to suppress rotation of the head 1 very much, it is not necessary to provide the structure which prevents idling from the above.
"Modification 1"

In the above-described embodiment, the contact member 5 is disposed on the head shaft portion 3, and the edges 54 a, 54 b, 54 c, 54 d of the lower end 51 b of the contact member 5 are in contact with the step portion 15 of the round hole 12. Although the configuration has been described, even when the contact member 5 is not disposed on the head shaft portion 3, the same effects as in the present embodiment can be obtained.
In this case, as shown in FIG. 13, the elastic member 7 is formed to have a large diameter so as to be able to come into contact with the step portion 15 of the round hole 12, and at the same time, the diameter of the seat surface portion 34 is also large. The elastic member 7 may be formed in a large diameter that can be fixed.
"Modification 2"

In the present embodiment, the case where the round hole 12 is provided in the neck connecting hole 11 of the head 1 and the neck 2 is connected to the round hole 12 has been described. However, the neck 2 is connected to the head 1 having another configuration. You may do it. For example, you may connect with the head 6 which provided the neck part connection hole 71 which consists of the rectangular long hole 62 long in the front-back direction which this inventor provides in patent document 2 (FIG. 13 ~). (See FIG. 15).
The neck connecting hole 71 of the head 6 is formed such that the peripheral edge 64 of the rectangular long hole 61 is raised in the head inner direction (the arrow direction in FIG. 15), and the outer peripheral edge of the neck connecting hole 71 is the head The mortar-shaped inclined surface 73 inclined toward the inner side is formed.
When connecting the head 6 and the neck 2, by fitting the grooves 53 a and 53 b formed in parallel with the lower end 51 b of the contact member 5 to the peripheral edge 64 of the long hole 61 of the head 6, The head 6 and the neck 2 are firmly connected.

  In this case, in addition to the effects of the present embodiment described above, the neck 2 is movable in the front-rear direction of the head 6 along the long hole 61, so the head shaft 3 is connected to the neck body 4. In contrast, the head 6 can be swung in the front-rear direction at a deeper angle by combining with the operation of swinging in the front-rear direction. As a result, it is possible to make the doll pose looking up at the sky or posing looking at the feet, which is impossible in the past.
