In order to realize natural movements like human limbs, it is desirable that they can rotate in various directions. On the other hand, by providing the hip joint inside the waist like a human, it is possible to realize a natural leg connected to the hip joint, but the operating space thereof is limited. That is, it is required to rotate the legs more freely in the space limited by the relationship with other members such as the waist and the skirt.

The present invention provides a mechanism for expanding the range of motion of the hip joint, for example, in a doll body, and realizing more flexible movements and various poses.

The present invention is, for example, a doll body, a hip joint portion to which the upper body portion is connected, and a hip joint portion provided at the rear portion of the hip joint portion and corresponding to the left and right legs, respectively. , One end of the sphere is rotatably connected to each connecting member whose rotatably supported hip joint and the other end of each connecting member are rotatably connected to both sides of the lumbar joint. It is characterized by having each leg.

Further, the present invention is, for example, a rotation mechanism of the hip joint portion and the leg portion of the doll body, and each hip joint corresponding to the left and right leg portions provided at the rear portion of the hip joint portion to which the upper body portion is connected. The first rotating portion in which one spherical end of each connecting member is pivotally supported, and the other end of each connecting member can be rotated near both sides of the lumbar joint. It is characterized in that it is provided with a second rotating portion for connecting the respective legs.

According to the present invention, in the doll body, the range of motion of the hip joint can be widened, and more flexible movements and various poses can be realized.

The rotation mechanism is an example of the third rotating portion, and the thigh and below of the leg portion 105 can be rotated in the directions of arrows 303 and 308 about the axial direction of the leg portion. Even below the knee (not shown), it is desirable that the knee and ankle are rotatably configured at least at the positions of the knee and ankle.

<Detailed composition of the waist>
Next, with reference to FIG. 4, the detailed configuration of the waist portion 104 according to the present embodiment will be described. FIG. 4A is a view of the lumbar foundation member 104a viewed from above, and FIG. 4b is a view of the lumbar foundation member 104a viewed from below. Further, FIG. 4 (c) is a perspective view seen from above, and FIG. 4 (d) is a view seen from the left side of the doll body 100.

The lumbar foundation member 104a includes a lumbar joint portion 401 and hip joint portions 402a and 402b. The hip joint portion 401 is a joint to which the upper body portion of the doll body 100 is connected, and a sphere (not shown) at the lower portion of the upper body portion is rotatably connected. This allows the upper body to rotate around the waist. The hip joint portion 401 is formed in a circular shape in order to rotatably receive a sphere in the lower part of the upper body portion. The hip joint portion 401 is formed with a diameter slightly shorter than the diameter of the sphere in the lower part of the upper body, and when the sphere is inserted, it is formed of an elastic member such as plastic. Can be done.

Further, the hip joint portions 402a and 402b corresponding to the left and right leg portions 105a and 105b are individually formed at the rear portions of the hip joint portions 401, respectively. That is, the left and right legs 105a and 105b are axially supported by different hip joints 402a and 402b, respectively, and can be operated individually. This makes it possible to realize more natural movements and various poses. Further, by providing the hip joint portions 402a and 402b at the rear portion of the waist portion 104, those shapes can be covered by the buttocks, decoration, and the like. Each of the hip joint portions 402a and 402b is formed in a circular shape, similarly to the hip joint portion 401. Further, as shown in FIG. 4A, the hip joint portion 401 and the hip joint portions 402a and 402b may be integrally formed. As a result, the strength of the hip joint portions 401 and the hip joint portions 402a and 402b can be increased, while the number of parts can be reduced and the manufacturing process can be simplified.

One ends of the connecting members 201a and 201b are pivotally supported at the hip joint portions 402a and 402b, respectively. Further, the left and right legs 105a and 105b are connected to the other ends of the connecting members 201a and 201b, respectively. According to the present embodiment, as shown in the figure, the hip joint portions 402a and 402b are intentionally formed at the rear portion of the hip joint portion 401 so as to be offset from the center of the doll body, and one ends of the connecting members 201a and 201b are pivotally supported there. Will be done. On the other hand, the other ends of the connecting members 201a and 201b are connected to the leg portions 105a and 105b in the vicinity of the lower side portion of the lumbar joint portion 401. In this way, the range of motion of the hip joint can be expanded as much as possible by ensuring the distance between one end of the axial support and the other end connecting the legs 105a and 105b as long as possible within the parts of the lumbar portion 104. can.

Here, with reference to FIG. 5, the connection of the connecting members 201a and 201b to the hip joint portions 402a and 402b will be described. FIG. 5A is a perspective view of the lumbar foundation member 104a seen from above, and FIG. 5B is a perspective view seen from below, showing how the connecting members are attached.

The connecting members 201a and 201b include one end (sphere) 501a and 501b formed in a spherical shape, and the other ends 502a and 502b having a cylindrical shape, respectively. As shown in FIG. 5B, the connecting member 201b is formed in an L shape from one end 501b toward the other end 502b. That is, the connecting members 201a and 201b according to the present embodiment are L-shaped so as to extend from the rear portion of the lumbar joint portion 401 to the corresponding side portions of the lumbar joint portion 401 according to the left and right leg portions 105a and 105b. Is formed by. Thereby, the distance from one end (rotation center) of the axially supported connecting member to the other end where the legs are connected can be secured as much as possible in the space of the waist portion 104. The connecting member 201a is also formed in the same manner.

In the present invention, there is no intention of limiting the connecting member to an L-shape. The L-shape is defined according to the configuration of the doll body 100 in order to secure the distance from one end to the other end as long as possible in a narrow part, for example, in the space inside the waist 104, and is defined by another person. In the form, any shape can be applied from the relationship with each member or the like. That is, the shape may be such that the distance between one end and the other end can be secured as much as possible in the limited space. Further, regarding the shape, when the leg portion 105 is operated, it may come into contact with other members to narrow the range of motion, so it is desirable to make the shape in consideration of the movement during movement. In addition to the above conditions, it is desirable that the shaft and the spherical portion have a shape that can be easily removed from the mold, and that the number of parts can be reduced as much as possible (preferably with one part). The L-shape is a shape that also satisfies these conditions.

As shown in FIGS. 5A and 5B, one end 501a and 501b of each connecting member 201a and 201b are mounted from below the hip joint portions 402a and 402b and are pivotally supported. The hip joint portions 402a and 402b are formed in a circular shape, and the diameter thereof is slightly shorter than the diameter of one end 501a and 501b which is a sphere, and when the sphere is inserted, it is formed of an elastic member such as plastic. Therefore, it can be bent by pressing to accept the sphere. As a result, the hip joint portions 402a and 402b can pivotally support the connecting members 201a and 201b. Here, an example in which the connecting members 201a and 201b are connected to the hip joint portions 402a and 402b from below has been described, but they may be connected from above due to spatial restrictions. In this case, it is desirable that the hip joint is located further below the hip joint. As a result, it is possible to secure as much space as possible in which the connecting member can rotate.

<Hip rotation mechanism>
Next, with reference to FIG. 6, the rotation mechanism of the hip joint portion according to the present embodiment will be described. The rotation mechanism of the hip joint portions 402a and 402b described below is an example of the first rotation portion.

FIG. 6A shows a cross-sectional view on the left side of the waist portion 104, showing how the connecting member 201b rotates in the front-rear direction. The dotted line 601 indicates the position where the connecting member 201b is rotated in the forward direction of the doll body 100 around one end 501b axially supported by the hip joint portion 402b. The dotted line 602 indicates the position where the connecting member 201b is rotated backward of the doll body 100 around one end 501b axially supported by the hip joint portion 402b. Therefore, the connecting member 201b axially supported by the hip joint portion 402b can obtain a range of motion in the range indicated by the dotted arrow 603 in the anteroposterior direction of the doll body 100. Further, since the leg portion 105b is further rotatably connected to the other end 502b of the connecting member 201b in the front-rear direction, the leg portion 105b can obtain a larger range of motion. The connecting member 201a also rotates in the same manner, and a similar range of motion can be obtained.

As described above, according to the present embodiment, the connecting member itself rotates in the front-rear direction around the hip joint portion, and the leg portion is rotatably attached to the connecting member. That is, according to the movement of the leg in the anteroposterior direction, the hip joint portion corresponding to the base of the leg can also follow and rotate in the anterior-posterior direction, and it is natural that the range of motion is widened. It is possible to realize dynamic movements and poses.

FIG. 6B shows a view of the lumbar portion 104 as viewed from above, and shows how the connecting members 201a and 201b rotate in the left-right direction. The dotted line 604a indicates a position where the connecting member 201a is rotated to the right of the doll body 100 around one end 501a axially supported by the hip joint portion 402a. The dotted line 605a indicates a position where the connecting member 201a is rotated to the left of the doll body 100 around one end 501a axially supported by the hip joint portion 402a. Therefore, the connecting member 201a axially supported by the hip joint portion 402a can obtain a range of motion in the range indicated by the dotted arrow 606a in the left-right direction of the doll body 100. Similarly, the dotted line 604b indicates a position where the connecting member 201b is rotated to the left of the doll body 100 around one end 501b axially supported by the hip joint portion 402b. The dotted line 605b indicates a position where the connecting member 201b is rotated to the right of the doll body 100 around one end 501b axially supported by the hip joint portion 402b. Therefore, the connecting member 201b axially supported by the hip joint portion 402b can obtain a range of motion in the range indicated by the dotted arrow 606b in the left-right direction of the doll body 100. As described above, in the rotation mechanism of the hip joint portion according to the present embodiment, the respective connecting members 201a and 201b and the respective leg portions 105a and 105b connected to the connecting members 201a and 201b can be individually rotated in the left-right direction. ..

As described above, in the rotation mechanism of the hip joint portion according to the present embodiment, since one ends 501a and 501b of the spherical shape are pivotally supported by the hip joint portions 402a and 402b, in addition to the front-back direction of the doll body 100, further in the left-right direction. Is also rotatable. Here, in order to simplify the explanation, the front-back direction and the left-right direction have been described, but since one end 501a and 501b are spherical and the hip joint portions 402a and 402b are formed in a circular shape, it is natural. It can also rotate in other directions. That is, according to the rotation mechanism of the hip joint portion according to the present embodiment, it is possible to rotate in all directions within the range of the space in the waist portion 104 of the doll body 100. This makes it possible to realize more natural movements and various poses.

For example, according to the configuration of the hip joint according to the present embodiment, it is possible to realize a posture of straddling a two-wheeled vehicle in a natural manner. In addition, by rotating the right leg of the doll body forward and bending the left leg and rotating it backward, one leg forward bending posture, for example, when jumping over a hurdle used in athletics. It is also possible to realize a pose like a posture. Further, by squeezing the connecting member inward to stand, a more natural standing posture in the inner thigh can be realized. Alternatively, various poses can be realized by opening the connecting member to the outside or rotating the left and right connecting members in the same right direction. As described above, according to the present embodiment, more natural movements and various poses can be realized.

As described above, the doll body according to the present embodiment is provided at the upper body portion, the hip joint portion to which the upper body portion is connected, and the rear portion of the hip joint portion, and the hip joints corresponding to the left and right legs, respectively. The portion, each connecting member whose spherical end is rotatably supported to the hip joint portion, and the other end of each connecting member are rotatably connected to both sides of the hip joint portion. It is characterized by having each leg. As described above, in the doll body according to the present embodiment, the hip joint portion and the connecting member form a first rotating portion capable of rotating the connecting member in multiple directions, and the connecting member and the leg portion form the front and rear of the doll body. A second rotating portion that can rotate the leg portion in the direction is formed. As a result, in the doll body, the range of motion of the hip joint is widened, and a mechanism for realizing more flexible movements and various poses is provided. Further, according to the present embodiment, the hip joint portions are each formed in a circular shape, and each connecting member can rotate in all directions within the space within the waist portion of the doll body, and one end thereof is axial to the hip joint portion. May be provided. Further, each leg portion may be configured to be rotatable about the axial direction of the leg portion (third rotation portion). As described above, according to the present embodiment, in addition to the first rotating portion and the second rotating portion, a third rotating portion that rotates the thigh and below may be further formed. This makes it possible to realize more natural movements and various poses.
