Description

  The present invention relates to a doll hip joint structure and a doll provided with the hip joint structure.

  As is well known, a doll that can move a joint can take a desired posture when the joint is moved, and it is necessary to maintain a beautiful appearance in each posture. However, in dolls made of hard materials, if joints are formed with priority on the appearance, adjacent members can interfere with each other and cannot take the desired posture. Forming a large gap between adjacent members and deteriorating the appearance, making it difficult to develop a joint that satisfies these two requirements.

  For example, in Patent Document 1 below, the waist is divided and connected to the lower end of the torso, and the left and right legs are connected to the lower leg. The left and right legs are composed of left and right thighs and left and right lower legs with left and right legs. Is provided with a connectable foot hook.

  As in the dolls disclosed in Patent Document 1 and Patent Document 2, when the leg members are connected by forming the crotch portion of the trunk member in a substantially V shape along the groin, the trunk member and the leg member It is difficult to create a gap between the hip joint and the hip joint. There was a problem of being in an open state.

  On the other hand, as in the doll disclosed in Patent Document 3, when the crotch portion of the trunk member is formed relatively horizontally and the leg members are connected, the doll disclosed in each Patent Document When the hip joint is bent, the opening of the crotch is lost, but there is a large gap between the body member and the leg member, and the joint between the two members becomes an unnatural shape, and the appearance is impaired. In addition, since the contact surface between the trunk member and the leg member is small, there is a problem that the stability of the hip joint in the standing posture is impaired.

  Therefore, the present invention is a doll whose crotch portion of the trunk member is formed in a substantially V shape along the groin portion and the leg member is connected, but the crotch is not opened even if the hip joint is bent. Obtaining a hip joint structure as a technical issue, and as a result of repeated trials and experiments to achieve its realization, the doll's hip joint structure in which the leg member is rotatably connected to the trunk member, Hip joint recesses are formed on both sides of the crotch part so that the crotch part is shaped along the groin, and hip joint protrusions are formed on the leg members so as to fit into the hip joint recesses. It is connected by a connecting hole formed so as to extend away from the rotation axis of the leg member, and is pulled to each other by a connecting elastic body spanned through the connecting hole in a state where the hip joint convex portions of both leg members are fitted into the hip joint concave portions, for If the connecting elastic body is guided to the upper front side of the rotating shaft along the connecting hole by bending the member, the opening of the crotch when the body member is bent with respect to the leg member can be restricted. We have obtained a remarkable knowledge that we can do it, and have achieved the technical problem.

  The technical problem can be solved by the present invention as follows.

  That is, the hip joint structure of a doll according to the present invention is a hip structure of a doll in which leg members are rotatably connected to the torso member, and the torso member has a shape between the crotch portion along the groin portion. The hip joint recesses are formed on both sides of the crotch part, and the leg member is formed with a hip joint convex part that fits into the hip joint recess. Are connected to each other by a connecting elastic body that is stretched through the connecting hole in a state where the hip joint convex portion is fitted in the hip joint concave portion. By bending the member, the connecting elastic body is guided upward and forward with respect to the rotation axis along the connecting hole.

  Further, according to the present invention, in the hip joint structure of the doll, the connecting elastic body is positioned below the rotation shaft in a state where the leg member is not bent with respect to the trunk member.

  In the hip joint structure of any one of the dolls according to the present invention, the connection hole is formed so as to extend on a concentric circle centering on the rotation axis of the leg member with respect to the trunk member.

  Further, according to the present invention, in any one of the above-described hip joint structures of a doll, the leg member and the torso member are formed in a hollow shape, and the torso member is in a state where the hip joint convex part of the leg member is fitted in the hip joint concave part of the torso member The hollow member and the hollow part of the leg member communicate with each other, and the leg member is pulled to the trunk member side by an elastic body passed from the hollow part of the trunk member into the hollow part of the leg member.

  The doll according to the present invention has the hip joint structure of any of the above dolls.

  According to the present invention, when the leg members are pulled together by the connecting elastic body that is passed through the connecting hole formed in the crotch portion and the leg member is bent with respect to the trunk member, the connecting elastic body becomes the connecting hole. Since it is configured to be guided and positioned on the upper front side with respect to the rotation shaft, when the leg member is bent with respect to the trunk member, the movement of opening the leg member caused by the interference between the hip joint concave portion and the hip joint convex portion And the movement of rotating the leg member outward is restrained by the pulling of the connecting elastic body positioned on the front upper side with respect to the rotation axis, and the crotch is closed when the leg member is bent with respect to the trunk member. Can keep.

  In addition, since the crotch portion has a shape along the groin portion, the width between the two hip joint recesses of the connecting hole also increases from the lower end to the upper end, and the hip joint is bent to be bent from the lower end to the upper end of the communication hole. Since the connecting elastic body guided to the part is in a more stretched state and the force for pulling the both leg members is increased, the connecting elastic body does not require the pulling force to the both leg members by the connecting elastic body. When the member is not bent, the traction force of the connecting elastic body is small, and the traction force of the connecting elastic body is large when the leg member is bent with respect to the body member that requires the pulling force to the both leg members by the connecting elastic body. Thus, the traction force of the connecting elastic body in each posture is adjusted to an appropriate magnitude.

  Therefore, it can be said that the industrial applicability of the present invention is very high.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the lower knee member 20, a groove 22 that is vertically divided in the front-rear direction is formed at a portion corresponding to the knee joint, and a hanging rod 23 is bridged over the groove 22.

Further, the hip joint structure of the doll 1 will be described in detail. As shown in FIG. 2 to FIG. The crotch portion 9 of the lower torso member 7 is formed in a substantially V shape along the groin by the both hip joint recesses 24. The hollow portion 10 branched at a position corresponding to the hip joint of the lower torso member 7 penetrates to a surface located above the both hip joint recesses 24 to form an opening 25. In addition, the crotch portion 9 of the lower torso member 8 has consolidated hole 26 is formed which penetrates so as to connect both hip recess 24, the connecting hole 26, as shown in FIG. 4, for lower torso member 7 It is formed so as to extend concentrically with the rotation axis of the above-knee member 19 (indicated by x in FIG. 4). The part is positioned on the front upper side with respect to the rotation axis. In addition, the groin part in this invention has shown the part which hits the base of the trunk | drum and leg which extend from a crotch to a hip bone in a human body.

  The left and right upper knee members 19 are formed with substantially spherical hip joint convex portions 27 that fit into the hip joint concave portions 24 of the lower torso member 7. As shown in FIG. 4, the hollow portion 21 that penetrates to the upper end of the above-knee member 19 forms an opening 28 that extends downward from the upper side toward the inner side of the crotch on the front surface of the hip joint convex portion 27. ing. Further, the hip joint convex portion 27 of the upper knee member 19 is formed with a raised portion 29 extending downward from the upper side toward the inner side of the crotch on the rear surface.

Therefore, by fitting the hip joint convex part 27 of the upper knee member 19 into the hip joint concave part 24 of the lower trunk member 7, the hollow part 10 of the lower trunk member 7 and the hollow part 21 of the knee upper member 19 are opened. with a state of communicating via the hole 25 and the hip protrusion 27 of the aperture 28, the hollow portion 21 of the knees upper member 19 via the consolidated hole 26 of the opening 28 and the crotch portion 9 of the hip protrusion 27 Communicated with each other.

  Next, the assembly mode of the doll according to the present embodiment will be described.

  As shown in FIG. 1, the left and right arm members 4 pass arm elastic bodies 30 across the hollow portions 8 of the upper torso member 6 and through the hollow portions of the respective members constituting both arm members 4, and the elastic bodies for arms. The both ends of 30 are hooked on a hanging tool provided on the left / right hand member 18 to be pulled to the upper body member 7 side and connected in a pressure contact state.

The left and right leg members 5 are formed by attaching a pair of leg elastic bodies 31 to the leg members 5 from the hollow portions 8 and 10 of the body member 3 through the openings 25 of the hip joint recesses 24 and the apertures 28 of the hip joint protrusions 27. The upper end of the elastic body 31 for both legs is hooked on the hanging tool 13 arranged at the tip of the neck 11 of the upper body member 6 and the lower end is hooked on the connecting tool 32 hung on the hanging rod 23 of the knee-lowering member 20. By being hooked, the body member 3 is pulled and connected in a pressure contact state. Furthermore, the connecting elastic body 33 through the hollow portion 21 of the legs members 5 across consolidated hole 26 of the crotch section 9, was subjected to both ends of the connecting elastic member 33 to the hanging rod 23 of the left and right knee member 20 connected By hooking through the tool 32, each leg member 5 is pulled to the opposite leg member 5 side and connected in a pressure contact state.

  The upper body member 6 and the lower body member 7 are pulled and connected to each other by the leg elastic bodies 31 passed through the hollow portions 8 and 10 of the both members.

  Next, the operation of the hip joint of the doll according to the present embodiment will be described.

  Before bending the hip joint, as shown in FIG. 6A, the connecting elastic body 33 passes through the lower end portion of the connecting hole 26 of the crotch portion 9 and is bridged between both leg members 5. It has become. However, when the hip joint is bent, as shown in FIG. 6B, the connecting elastic body 33 is guided along the connecting hole 26 of the crotch portion 9 and passes through the upper end portion of the connecting hole 26, and the both leg members 5. It will be in a state of being bridged between. At this time, since the crotch portion 9 has a shape along the inguinal portion, the hip joint concave portion 24 and the hip joint convex portion 27 interfere with each other to open the leg member 5 (in FIG. 5B, an arrow A) works and a force for rotating the leg member 5 (arrow B in FIG. 5B) works. However, since the connecting elastic body 33 is positioned on the front side with respect to the rotating shaft 34, a force that closes the leg member 5 acts with the rotating shaft 34 as a fulcrum, and the connecting elastic body 33 moves upward with respect to the rotating shaft 34. Therefore, a force that rotates the leg member 5 inward with the rotating shaft 34 as a fulcrum acts, and these two forces restrict the force generated by the interference between the hip joint recess 24 and the hip joint protrusion 27.

  Further, since the crotch portion 9 has a shape along the groin portion, the width between the two hip joint recesses 24 of the connecting hole 26 increases from the lower end to the upper end, and the hip hole is bent to allow the communication hole 26 to be bent. The connecting elastic body 33 guided from the lower end portion to the upper end portion is in a more extended state, and the force for pulling both the leg members 5 is increased.

  Therefore, the two forces acting on the leg member 5 when the leg member 5 is bent with respect to the body member 3 are regulated by the traction force of the connecting elastic body 33, and the sitting posture can be beautifully maintained.

  The division positions of the trunk member, arm member, and leg member are not limited to the division positions of the trunk member, arm member, and leg member of the doll according to the embodiment, and may be divided at different positions. , It does not have to be divided.

  Examples of the elastic body include a rubber string and a spring. However, the elastic body is not limited to these, and any elastic body may be used as long as it has a tension that can be pulled so that each member does not leave. Further, the leg elastic body in the above embodiment is not directly fixed to the lower torso member and the upper knee member constituting the hip joint of the doll, and is provided on the upper torso member and the lower knee member across the two members. Although it is being fixed to the hanging tool, it can also be directly fixed to a member constituting the hip joint of the doll.

  Further, the doll according to the above embodiment is a doll in which the torso member and the leg member are pulled and connected by the leg elastic body, but the hip joint structure of the doll according to the present invention includes the torso member and the leg member. The present invention can also be applied to a doll connected by another method (for example, a doll in which a hip joint concave portion of a trunk member and a hip convex portion of a leg member are connected via a shaft member).

It is the top view which showed the mode of the elastic body passed through the hollow part of the doll which concerns on Embodiment 1 with the dotted line. It is the fragmentary sectional view which showed the hip joint of the doll shown in FIG. It is the disassembled perspective view which showed the hip joint of the doll shown in FIG. It is AA sectional drawing of the hip joint of the doll shown in FIG.
