Description

  The present invention relates to a hip joint structure of a doll toy in which the movement of the hip joint is realistic.

  2. Description of the Related Art Conventionally, various types of dress-up doll toys have joints in which arms, legs, and the like are matched to human movements.

  For example, as shown in FIG. 4, the hip joint 3 is formed at the center of the lower surface of the waist 1, and the thigh is connected to the left and right sides of the hip 3 via joint members 15. Things are known. This is because the joint member 15 has a disc shape, a pivot shaft 16 projects from the crotch portion side, and the pivot shaft is connected to the side portion of the crotch portion so as to be pivotable back and forth, 15 is fitted into a groove formed on the left and right at the upper end of the thigh, and is connected to the thigh and the left and right via a shaft 17 at the center of the joint member. However, this alone only moved the thigh forward and backward and inward and outward, and the thigh could not be turned to the right or left. This makes it impossible to turn right or left with the legs closed.

  In order to improve this, the thigh is divided into upper and lower parts, and the upper part 18a and the lower part 18b are rotatably connected by the central shaft 19. Thereby, since the lower part of the thigh can be rotated around the center line of the leg, the leg part can be freely turned to the right or left with the leg part closed.

  However, in the structure in which the lower part of the thigh is freely rotated around the center line of the leg, the back side of the knee can be turned to the front side, so that there is a problem that the realism is deteriorated. It was.

  It is an object of the present invention to provide a hip joint structure of a doll toy that can solve the above-described problems and can realistically realize a movement similar to that of a human hip joint with a simple structure.

The hip joint structure of a doll toy according to the present invention is characterized by having the following requirements.
(B) A crotch part is formed at the center of the lower surface of the waist part, and the thighs are connected to the left and right sides of the crotch part via spherical joint members.
(B) A concave surface opening to the crotch portion is formed on the upper part of the thigh, and a spherical joint member is rotatably disposed on the concave surface. (C) The joint member The crotch part side is connected to the side part of the crotch part so as to be able to rotate back and forth.

  The joint member is formed by sandwiching a disk body rotatably connected around a first rotation axis between two spherical bodies, and the two spherical bodies are connected on one side, In addition, a second rotating shaft and a third rotating shaft are formed so as to protrude outward from the connecting portion and outward from the disc body, respectively, and can be rotated back and forth around the crotch portion via the second rotating shaft. It is preferable that it is movably coupled and is pivotally coupled to the bottom of the concave surface portion of the thigh via a third pivot shaft.

  According to the first aspect of the present invention, the thigh can be rotated back and forth around the connecting portion of the crotch portion and can be rotated around the joint member. The movement is limited to the point where the edge of the concave part of the thigh hits the connecting part on the crotch part side. Therefore, a movement similar to the movement of a human hip joint can be realized realistically with a simple structure.

  According to the invention of claim 2, the thigh is moved back and forth around the second axis of the joint member, inside and outside around the center of rotation of the disc body, and left and right around the third axis. Can be rotated.

  The joint member is pivotally sandwiched between two spherical bodies to form a spherical shape as a whole, and is connected to the crotch portion of the doll via a second axis formed on the spherical body. It is preferable to connect to the thigh through a third shaft formed on the plate.

  FIG. 1 is a front view of a waist part of a doll toy. Reference numeral 1 denotes a waist part, and 2 denotes a thigh part.

  The waist part 1 is formed hollow, and a crotch part 3 is formed at the center of the lower surface thereof. Both sides of the crotch part are formed in a planar shape that continues back and forth. A buttock is formed at the rear of the crotch portion 3.

  The crotch part 3 is also formed hollow, and the thigh part 2 is connected to the left and right sides via spherical joint members 4. A concave surface portion 6 that opens to the crotch portion 3 side is formed at the end of the thigh 2.

  The inner surface of the concave surface portion 6 and the outer surface of the joint member 4 are formed so that the joint member 4 is rotatably fitted inside the concave surface portion 6.

  As shown in FIG. 2, the joint member 4 has a structure in which a disc body 8 that is rotatably connected between two spherical bodies 7 that are slightly smaller than the hemisphere is sandwiched, and from the center of one spherical body 7. The inserted first rotation shaft 10 passes through the center of the disc body 8 and is fixed to the other spherical body 7. The two spherical bodies 7 are connected to each other through a connecting portion 9 on one side. A second rotating shaft 11 and a third rotating shaft 12 project from the outer side of the connecting portion 9 of the spherical body 7 and the outer side of the disc body 8, respectively.

  Next, as shown in FIG. 3, the joint member 4 is connected to the second rotation shaft 11 through the crotch portion 3 so as to be rotatable forward and backward. Further, the third rotation shaft 12 is connected to the bottom wall of the concave surface portion 6 of the thigh 2 so as to be rotatable left and right. Note that the second rotation shaft 11 may also be used as the joint members 4 on the left and right sides.

  According to the above configuration, the thigh 2 can be rotated back and forth around the second rotation shaft 11, and can be centered around the first rotation shaft 10 and the third rotation shaft 12. And turn freely. That is, since the disk body 8 is rotatable around the first rotation shaft 10, the thigh 2 can be opened and closed in the inner and outer directions. Furthermore, the periphery of the third rotation shaft 12 formed on the disc body 8 can be rotated left and right. Therefore, it can be turned to the right or left with the legs closed.

  Note that the rotation of the thigh 2 is not unlimited. The front and rear pivot ends are limited to where the thigh 2 hits the lower surface and buttocks of the waist 1 and the inner pivot end hits the crotch portion 3, respectively. The rotation end is limited to a place where the edge of the concave surface portion 6 of the thigh 2 abuts against the second rotation shaft 11 (dotted line portion in FIG. 1). Therefore, the unnatural movement of the thigh 2 can be prevented by the size of the concave portion 6. Therefore, with a simple structure, it is possible to realize realistic movement similar to that of a human hip joint.
