Description

The present invention relates to a soft resin doll that includes a hard resin skeleton and is covered with a soft resin outer shell.
In this specification, a doll is not limited to a doll having a trunk, legs, arms, and head, but also includes a doll that does not have a head, legs, or arms.
In addition, it is not limited to human shapes, and if it has a chest skeleton, it can be used to display the usage status of products such as clothes and clothing, including animals such as dogs and cats, and non-living animals such as robots. All dolls are targeted.

In the recent doll industry, dolls having a configuration that faithfully replicates the human body (naked body) form, particularly called figures, are gaining popularity among customers.
The figure dolls are usually played by girls and the like, or simply dressed up, but recently the demand for figures has changed, especially for adult male users. Because of the increasing number, the way of playing is changing.
In other words, with figures that move limbs, waists, etc., for example, with naked or wearing various costumes, you can take the posture you want and decorate it on shelves or cases while maintaining that posture, Or there is a taste to enjoy taking a picture. Even for dolls that do not move, such as limbs and hips, they are decorated with costumes that suit the consumer's tastes and are photographed.
Further, for example, in the case of a movable doll used in an art drawing or the like, the limbs and the waist are bent arbitrarily so that the posture to be drawn is taken and the drawing is performed.

In the above-described case, a pose that is faithful to the movement of the human body is desired, because the pose of the work performed by the human is replaced with a doll. In order to respond to such demands, the applicant of the present application has conventionally developed a soft resin doll in which a skeletal structure that can be bent at each joint location of the body such as arms and legs is covered with a soft resin outer skin. (See Patent Document 1).
In the skeleton structure of the soft resin doll, a chest skeleton, a pair of shoulder skeletons connected to the chest skeleton, a neck skeleton connected above the chest skeleton, and a torso skeleton connected below The lumbar skeleton is connected to the lower part of the torso skeleton, and the left and right leg skeletons are connected to the lumbar skeleton. (See FIG. 1 of Patent Document 1).
The arm skeleton includes an arm skeleton connecting portion extending to the side surface of the doll, and the chest skeleton is rotatably inserted and connected to the connecting portion.

By the way, the actual human has a large movable range from the chest to the shoulder, and the impression received by the viewer changes depending on the positional relationship between the portions, and the strength and bewitching are remarkably expressed. An example of such an impression would be a glossy impression if it is a shoulder, and it will appear large and strong if it is a shoulder. In addition, it is a delicate impression if it is a stoop, and a full and bright impression if it is a pigeon breast.
In addition, various exercises are performed by performing complicated movements from the chest to the shoulder. For example, in martial arts, one shoulder is taken forward and the arm is brought to the front of the body, while the other shoulder is deflected to the back of the body to accumulate attack power. Although it may take a posture, it is possible to take such a posture because the left and right shoulders can be freely moved back and forth and up and down.
Alternatively, you can emphasize your bust by pulling your shoulders forward and narrowing your arms toward the center of the body, and you may be popular with talented poses.
Therefore, in order to give the conventional doll more expressive power, there has been a demand for a chest skeleton structure that realizes a movement closer to an actual human being.

It is arranged at a position facing the hole 33a. Thereby, a screw (not shown) is inserted from the lower side of the front protrusion joint portion 41, and the screw is tightened into the screw hole 33a of the joint surface 33 of the front protrusion 30 so that the trunk side spine member C2 and the neck side spine member C1 is connected and fixed integrally.
The front surface of the anterior projection joint 41 is formed as a vertical surface, and the vertical surface is formed so as to be continuous with the lower end of the sternum surface 31 when the anterior projection 30 is joined.

A neck side spine bearing portion 42 is formed on the rear side of the trunk side spine axis D2.
The neck side spine bearing portion 42 is formed in a disc shape having a plane perpendicular to the vertical direction of the doll, and a through hole 43 penetrating vertically is formed in the center of the disc surface. Further, a circular recess 42b into which the lower end surface 12 of the neck side spine shaft D1 can be fitted is formed on the upper surface 42a of the neck side spine bearing portion 42.
When the projection 22a of the trunk side spine shaft D2 is fitted into the fitting hole 34a of the trunk side spine receiving portion 34 of the neck portion spine member C1, the neck side spine bearing portion 42 has an upper surface. The lower end surface 12 of the neck side spine axis D1 is disposed at a position and height where the lower end surface 12 of the neck side spine axis D1 is fitted in the recess 42b of 42a.

In a state where the lower end surface 12 of the neck side spine axis D1 is fitted in the recess 42b, a screw (not shown) is inserted from the lower side of the neck side spine bearing portion 42, and the screw is a lower end surface of the neck side spine axis D1. 12 is fastened to the neck side spine bearing portion 42 without the neck side spine axis D1 being shaken, and the trunk side spine member C2 and the neck side spine member C1 are integrally connected and fixed. The
A rear end portion of the neck side spine bearing portion 42 is provided with a pair of protrusions 44 and 44 protruding symmetrically about the neck side spine axis D1 on the disc-shaped outer peripheral surface.

Each of the pair of shoulder back-and-forth rotation structures C3 includes a horizontal rotation unit 50 that rotates in the horizontal direction around the neck-side spine axis D1, and a plate shape that extends from the horizontal rotation unit 50. And the member 52.
The horizontal direction rotation part 50 is formed in the cylinder which has a disk surface in the up-down direction (the same as the up-down direction of a figure, see the arrow in a figure) of a doll. Further, the hole 51 at the center of the diameter of the cylinder is formed to have a diameter slightly larger than the outer diameter of the neck side spine axis D1, and the inner diameter peripheral surface of the hole 51 is partly on the neck side. A small-diameter portion 51a that is slightly smaller than the outer diameter of the spine axis D1 is formed. In the present embodiment, the small-diameter portion 51a has a small diameter by forming three straight portions in the circular inner diameter of the hole 51 in a sectional view. In addition, the small diameter part 51a is continuously formed in the axial direction on the inner peripheral surface.
Thereby, when the horizontal direction rotation part 50 is externally fitted to the neck side spine axis D1, it rotates around the neck side spine axis D1 (spine axis D) in the horizontal direction (the arc-shaped arrow A and FIG. 2). (See FIG. 3A). In this case, only the small-diameter portion 51a slides in contact with the outer peripheral surface of the horizontal rotation portion 50, realizing moderate astringency at the time of rotation, and the shoulder skeleton S can be arbitrarily set. The rotation angle can be maintained.

In addition, the outer diameter of the horizontal direction rotation part 50 is formed in the same diameter as the collar part 10 of the said neck side spine member C1.
Moreover, one horizontal direction rotation part 50 is fitted by the neck side spine axis | shaft D1 so that it may contact | abut to the lower surface of the collar part 10 among a pair of horizontal direction rotation parts 50, and the other horizontal direction rotation part 50 is externally fitted to the neck-side spine axis D1 so that the upper surface thereof is in contact with the lower surface of the one horizontal rotation portion 50. At this time, the radial thickness of the horizontal rotating portion 50 is accommodated in the gap 35a between the reinforcing plate 35 of the neck side spine member C1 and the neck side spine axis D1.
The plate-like member 52 is extended from a part continuous in the axial direction of the outer diameter surface of the horizontal rotating portion 50 to a straight plate-like body outward in the radial direction. Further, the plate-like member 52 is directed downward to a height at which the protrusion 44 of the neck side spine bearing portion 42 is located when the horizontal rotation portion 50 is externally fitted to the neck side spine shaft D1 as described above. It extends vertically. In other words, in order to align the lower end 52 a of the plate-like member 52 with the position of the protrusion 44, the extension lengths of the pair of horizontal direction rotating portions 50 are different.

Further, when the pair of horizontal rotation parts 50 are externally fitted to the neck side spine axis D1, the plate-like members 52 extended to the respective horizontal direction rotation parts 50 mutually connect the neck side spine axis D1. It is arranged on the opposite side across.
Thereby, when the horizontal direction rotation part 50 rotates around the neck side spine axis | shaft D1 toward the back side of a doll, the surface of the lower side part 52a of the plate-shaped member 52 contact | abuts with the processus | protrusion 44. At this angle, further rotation is restricted. Therefore, when the installation positions of the projections 44 and 44 are set so that the rear surface of the lower end portion 52a of the plate-like member 52 comes into contact with the projection 44 when the rotation reaches a desired angle, the horizontal rotation is achieved. The rotation of the moving part 50 can be limited at a desired angle.

The pair of shoulder vertical rotation structures C4 includes a vertical rotation unit 60, a rotation unit support unit 61 that rotatably supports the vertical rotation unit 60, and a shoulder skeleton support unit 70, respectively. Consists of.
The vertical rotation portion 60 extends horizontally toward the rear side of the doll, and extends from the rotation shaft 64 serving as the rotation center of the vertical rotation portion 60 and the front end of the rotation shaft 64. And a shoulder skeleton support portion 70 provided at the upper end of the arm 65.

The arm 65 is a straight plate-like body formed with a predetermined thickness in the front-rear direction of the doll, and extends upward from the front end of the rotating shaft 64 with a predetermined dimension.
The shoulder skeleton support portion 70 is formed in a cylindrical shape having an outer diameter surface 72 having a diameter larger than the thickness of the arm 65 with the diameter axis oriented in the left-right direction of the doll.
As shown in FIG. 1B, the shoulder skeleton support portion 70 is disposed so as to be positioned between the neck side spine axis D1 and the trunk side spine axis D2. In addition, the rear end of the outer diameter surface 72 of the shoulder skeleton support portion 70 is located behind the rear surface of the arm 65.
Further, the right end of the shoulder skeleton support portion 70 to which the shoulder skeleton S on the right side of the front view is connected is formed to protrude to the right side from the right end of the arm 65, and the shoulder skeleton S on the left side of the front view is connected. The left end of the shoulder skeleton support portion 70 is formed to protrude to the left side from the left end of the arm 65.

The hole 71 at the center of the diameter of the cylinder of the shoulder skeleton support portion 70 is formed so that the connecting shaft S1 of the shoulder skeleton S can be fitted therein. In this case, the hole 71 is formed to be slightly larger in diameter than the outer diameter of the connecting shaft S1, and the inner diameter circumferential surface of the hole 71 is partially slightly smaller in diameter than the outer diameter of the connecting shaft S1. A small-diameter portion 71a is formed. In the present embodiment, the small-diameter portion 71a has a small diameter by forming three straight portions out of the circular inner diameter of the hole 71 in a sectional view. In addition, the small diameter part 71a is continuously formed in the axial direction on the inner peripheral surface.
Thereby, when the connecting shaft S1 is fitted in the hole 71, only the small diameter portion 71a slides in contact with the outer peripheral surface of the connecting shaft S1, and the shoulder skeleton S is attached to the shoulder skeleton support portion 70. It is possible to rotate along the axial center of the cylinder, and achieve moderate astringency during rotation, and the shoulder skeleton S can be held at an arbitrary angle.

The rotating portion support portion 61 has a cylindrical body that is orthogonal to the front surface of the plate member 52 from the front surface on the lower end 52a side of the plate member 52 toward the front side. It protrudes horizontally with respect to the axis of the lateral spine axis D1. At the center of the diameter of the cylindrical body, a rotation portion support hole 62 for rotatably supporting a vertical rotation portion 60 described later is formed.
That is, the rotation part support hole 62 has a virtual extension at a predetermined position (dimension of the arrow L) of a virtual extension line L (see the broken line arrow L in FIG. 2) perpendicular to the neck spine axis D1 in the horizontal direction. A virtual horizontal axis E (see a two-dot chain line E in FIG. 2) perpendicular to the line L in the horizontal direction is formed as the center of the diameter.
The rotating portion support portion 61 projects from the front surface on the lower end 52 a side of the plate-like member 52 so that the rear end of the outer surface 72 of the shoulder skeleton support portion 70 corresponds to the arm 65. The dimension is set to be slightly larger than the dimension protruding from the rear surface. Moreover, the outer diameter of the rotation part support part 61 is set to a smaller diameter than a predetermined dimension in which the arm 65 extends upward.

In the shoulder vertical rotation structure C4, the rotation shaft 64 of the vertical rotation portion 60 is fitted into the rotation portion support hole 62 of the rotation portion support portion 61 so that the shaft core ( When rotating around the virtual horizontal axis E), the shoulder skeleton S connected to the shoulder skeleton support 70 is rotated in the vertical direction (see the arrow B in FIG. 2 and FIG. 3B). ).
Although not shown, a screw hole is provided in the rear end portion of the rotation shaft 64. After the rotation shaft 64 is fitted into the rotation portion support hole 62 of the rotation portion support portion 61, a countersunk screw is tightened from the rear side of the rotation portion support hole 62, thereby supporting the rotation portion. The hole 62 is held so as not to fall off.

Below, the change of the attitude | position of the soft resin doll using the chest frame | skeleton structure C by this invention is demonstrated.
First, as shown in FIG. 4A, when the shoulder skeletons S and S are rotated in the forward direction of the doll, the posture of the soft resin doll is that the shoulder skeletons S and S are moved in the forward direction of the doll. The posture is changed from the posture when it does not rotate (see FIG. 4B) to the posture shown in FIG. 4C. In this case, the shoulder joints S2 and S2 of the doll move forward by the rotation of the shoulder skeletons S and S, and are pulled by the shoulder joints S2 and S2, and the shoulder portion of the outer FS of the resin doll skin FS. Is moving forward. Along with this, a part imitating the clavicle and a bust M are brought to the center of the body. At this time, the outer skin FS sags, and the force that moves the decollete part F toward the inside of the body works. However, the decollete part F is supported by the sternum surface 31 of the front protrusion 30 from the inside of the doll. There is no natural depression. Thereby, the soft resin doll can give a delicate impression on the back of the neck.

  Next, as shown in FIG. 5A, when the shoulder skeletons S and S are rotated in the rear direction of the doll, the posture of the soft resin doll is that the shoulder skeletons S and S are placed behind the doll. The posture changes from the posture in the case of not rotating in the direction (see FIG. 5B) to the posture shown in FIG. In this case, the shoulder joints S2 and S2 are moved backward by the rotation of the shoulder skeletons S and S, and the shoulder joints S2 and S2 are pulled by the shoulder joints S2 and S2. Is moving backwards. Along with this, the part imitating the clavicle and the bust M are pulled in the body side direction. At this time, the decollete portion F of the outer skin FS is subjected to a force that is flattened by pulling the outer skin FS left and right. So, like a real person, the central part of the chest keeps its position in the forefront. As a result, the soft resin doll can have a bright and bright impression with a pigeon chest.

  Next, as shown in FIG. 6 (a), when the shoulder skeletons S and S are rotated downward, the position of the soft resin doll is that the shoulder skeletons S and S are under the doll. The posture changes from the posture in the case of not rotating in the direction (see FIG. 6B) to the posture shown in FIG. 6C. In this case, the shoulder joints S2 and S2 of the doll are moved downward by the rotation of the shoulder skeletons S and S, and are pulled by the shoulder joints S2 and S2, and the shoulder portion of the outer FS of the resin doll skin FS. Is moving downward. Along with this, the part from the neck to the shoulder and the part that imitates the collarbone are pulled downward. As a result, the soft resin doll can have a glossy impression on the shoulder.

  Next, as shown in FIG. 7 (a), when the shoulder skeletons S and S are rotated upward, the position of the soft resin doll is that the shoulder skeletons S and S are placed on the doll. The posture changes from the posture in the case of not rotating in the direction (see FIG. 7B) to the posture shown in FIG. 7C. In this case, the shoulder joints S2 and S2 of the doll are moved upward by the rotation of the shoulder skeletons S and S, and are pulled by the shoulder joints S2 and S2, and the shoulder portion of the outer FS of the resin doll skin FS. Is moving upward. Along with this, the portion imitating the clavicle and the bust M are pulled upward. As a result, the soft resin doll can look like a large handle on the shoulder and give a strong impression.

In the thoracic skeletal structure C of the present embodiment, the spine axis D (the neck side spine axis D1 and the trunk side spine axis D2) is provided vertically along the vertical axis of the doll. Thereby, in the shoulder back-and-forth turning structure C3, the shoulder skeleton S can turn around the neck-side spine axis D1 in the front-back direction from the forefront to the end with only pure horizontal displacement. That is, the vertical displacement can be eliminated from the pivoting operation in the front-rear direction.
Moreover, in the shoulder part vertical rotation structure C4, it rotates centering on the virtual line E projected horizontally with respect to the neck side spine axis | shaft D1. As a result, the shoulder skeleton S can be rotated in the vertical direction from the top to the bottom only with pure vertical displacement. That is, the displacement in the front-rear direction can be excluded from the pivoting operation in the up-down direction.

  Of course, the shoulder skeleton S can be displaced to any position in the front / rear / up / down direction by combining the rotation of the shoulder front / rear rotation structure C3 and the rotation of the shoulder vertical rotation structure C4. It is possible to make a doll make a complicated pose. For example, the left shoulder skeleton S can be rotated backward and upward, and the right shoulder skeleton S can be rotated forward and downward. Such posing enables dynamic and rich pose expressions such as a tennis serve posture and a martial art attack preparation and defense posture.

In the present embodiment, the example in which both the shoulder front / rear rotation structure C3 and the shoulder vertical rotation structure C4 are provided has been described. However, the present invention is not limited to this configuration, and the shoulder front / rear rotation structure C3 and the shoulder part are provided. The case where only one of the vertical rotation structures C4 is provided is also within the scope of the present invention.
The spine axis D is divided into a neck side spine axis D1 formed on the neck side spine member C1 and a trunk side spine axis D2 formed on the trunk side spine member C2, and the neck side spine axis D1 is divided into the trunk side. Although arranged in parallel with the spine axis D2 and offset in the rearward direction of the doll, the arrangement is not limited to this configuration, and the divided neck side spine axis D1 and trunk side spine axis D2 are not limited to this configuration. It is within the scope of the present invention to have a configuration in which the shafts are arranged on one axis without being offset, or the spine axis D is continuously formed without being divided. In addition, a configuration in which the neck-side spine axis D1 is not parallel to the trunk-side spine axis D2 but is arranged at an angle is also within the scope of the present invention.

  In this embodiment, the plate-like member 52 and the arm 65 are formed in a straight plate-like body. However, the present invention is not limited to this, and the plate-like member 52 and the arm 65 may be formed as curved plates in the front-rear direction and the left-right direction. Moreover, the structure which is not provided with the trunk | drum side spine member C2 but is provided with the trunk | drum skeleton connection part 20 which can connect the trunk | drum skeleton T to the neck side spine member C1 is also within the scope of the present invention. In this case, the horizontal rotation part 50 may be prevented from falling off from the neck side spine axis D1 by, for example, tightening a countersunk screw into the screw hole 12a of the lower end surface 12 of the neck side spine axis D1. .
