According to the present invention, it is possible to provide a joint structure of a doll that can expand the movable range.
図１及び図２は、本発明の実施形態を説明するための、人形体の関節構造の一例の構成を示す。
1 and 2 show a configuration of an example of a joint structure of a doll body for explaining an embodiment of the present invention.
図１及び図２に示す人形体の関節構造１は、股関節の関節構造であって、関節部材３を有する胴体部分（第１部分）２と、腿部分（第２部分）４とを備え、腿部分４を人形体の前後方向に振るように且つ人形体の左右方向に開くように動かすことが可能に構成されている。
The doll body joint structure 1 shown in FIGS. 1 and 2 is a hip joint structure, and includes a body part (first part) 2 having a joint member 3 and a thigh part (second part) 4. The thigh portion 4 can be moved so as to swing in the front-rear direction of the doll body and to open in the left-right direction of the doll body.
関節部材３は、腿部分４を人形体の前後方向に振ることができるように、人形体の左右方向に延びる関節部材３の中心軸線Ｘまわりに回動可能に胴体部分２に連結されている。
The joint member 3 is connected to the body portion 2 so as to be rotatable about the central axis X of the joint member 3 extending in the left-right direction of the doll body so that the thigh portion 4 can be swung in the front-rear direction of the doll body. . *
腿部分４は、芯部材５と、芯部材５を覆う外装部材６とを有する。
The thigh portion 4 includes a core member 5 and an exterior member 6 that covers the core member 5.
芯部材５は軸部材７を介して関節部材３に回動可能に連結されている。軸部材７は、腿部分４を人形体の左右方向に開くことができるように、人形体の前後方向に延設されている。軸部材７を介して関節部材３に回動可能に連結された腿部分４は、関節部材３の中心軸線Ｘに対して屈曲可能に構成されている。
The core member 5 is rotatably connected to the joint member 3 via the shaft member 7. The shaft member 7 extends in the front-rear direction of the doll body so that the thigh portion 4 can be opened in the left-right direction of the doll body. The thigh portion 4 rotatably connected to the joint member 3 via the shaft member 7 is configured to be bendable with respect to the central axis X of the joint member 3.
腿部分４の中心軸線Ｙは、腿部分４が関節部材３の中心軸線Ｘに対して屈曲された状態（図１）で、関節部材３の中心軸線Ｘと交差し、人形体の上下方向に延びている。軸部材７は、人形体の左右方向に延びる関節部材３の中心軸線Ｘ及び人形体の上下方向に延びる腿部分４の中心軸線Ｙの各々の中心軸線に交差する方向に延設されている。
The center axis Y of the thigh portion 4 intersects the center axis X of the joint member 3 in a state where the thigh portion 4 is bent with respect to the center axis X of the joint member 3 (FIG. 1), and extends in the vertical direction of the doll body. It extends. The shaft member 7 extends in a direction intersecting with the center axis line of each of the center axis line X of the joint member 3 extending in the left-right direction of the doll body and the center axis line Y of the thigh portion 4 extending in the up-down direction of the doll body.
そして、軸部材７は、腿部分４が屈曲された状態で、腿部分４の中心軸線Ｙの屈曲外側に配置されている。さらに、図示の例では、軸部材７は、腿部分４が屈曲された状態で、関節部材３の中心軸線Ｘの屈曲外側に配置されている。なお、関節部材３と腿部分４とによって形成される内角θが位置する側を「屈曲内側」といい、関節部材３の中心軸線Ｘに対して内角θが位置する側の反対側を「関節部材３の中心軸線Ｘの屈曲外側」というものとする。または、腿部分４の中心軸線Ｙに対して内角θが位置する側の反対側を「腿部分４の中心軸線Ｙの屈曲外側」というものとする。
The shaft member 7 is disposed outside the bent side of the central axis Y of the thigh portion 4 in a state where the thigh portion 4 is bent. Further, in the illustrated example, the shaft member 7 is disposed outside the bent center axis X of the joint member 3 with the thigh portion 4 being bent. The side on which the inner angle θ formed by the joint member 3 and the thigh portion 4 is located is called “bending inside”, and the side opposite to the side on which the inner angle θ is located with respect to the central axis X of the joint member 3 is called “joint”. It is referred to as “bending outside of the central axis X of the member 3”. Alternatively, the side opposite to the side where the inner angle θ is located with respect to the central axis Y of the thigh portion 4 is referred to as “bending outside of the central axis Y of the thigh portion 4”.
また、図示の例では、腿部分４が屈曲された状態で中心軸線Ｙの屈曲外側に配置されている腿部分４の外側部位において、腿部分４の関節部材３側の一方の端部８は、他方の端部９と軸部材７を挟んで反対側に配置されている。
Further, in the illustrated example, one end portion 8 of the thigh portion 4 on the side of the joint member 3 is located outside the thigh portion 4 disposed outside the center axis Y with the thigh portion 4 bent. The other end 9 and the shaft member 7 are disposed on the opposite side.
図２に、腿部分４が軸部材７を回動中心にして展開された際の端部８の円軌道Ｔ１を示す。また、腿部分４が屈曲された状態での関節部材３及び腿部分４の各々の中心軸線Ｘ、Ｙの交点をＯとして、交点Ｏを中心として端部８が通る円軌道Ｔ２を併せて示す。
FIG. 2 shows a circular trajectory T1 of the end portion 8 when the thigh portion 4 is deployed around the shaft member 7 as a rotation center. Further, an intersection point of the central axes X and Y of the joint member 3 and the thigh part 4 in a state where the thigh part 4 is bent is defined as O, and a circular trajectory T2 through which the end part 8 passes through the intersection point O is also illustrated. .
軸部材７を関節部材３の中心軸線Ｘの屈曲外側かつ、腿部分４の中心軸線Ｙの屈曲外側に配置することにより、軸部材７を回動中心にして展開された際の端部８の回動半径ｒ１を円軌道Ｔ２の半径ｒ２よりも小さくできる。それにより、腿部分４の中心軸線Ｙの屈曲外側に配置されている端部８の通過軌跡長を縮小することができ、端部８が例えば胴体部分２と干渉する可能性を低減し、関節構造１の可動範囲を拡大することができる。
By disposing the shaft member 7 on the outer side of the center axis X of the joint member 3 and on the outer side of the center axis Y of the thigh 4, the end member 8 when the shaft member 7 is deployed around the center of rotation is arranged. The turning radius r1 can be made smaller than the radius r2 of the circular orbit T2. Thereby, it is possible to reduce the passage trajectory length of the end portion 8 arranged on the bent outer side of the central axis Y of the thigh portion 4, and to reduce the possibility that the end portion 8 interferes with the body portion 2, for example. The movable range of the structure 1 can be expanded.
図示の例のように、腿部分４の関節部材３側の一方の端部８が腿部分４の他方の端部と軸部材７を挟んで反対側に配置されている場合に、腿部分４の展開に伴い端部８が例えば胴体部分２と干渉する可能性が高くなるので、特に有用である。
When the one end portion 8 on the side of the joint member 3 of the thigh portion 4 is disposed on the opposite side of the other end portion of the thigh portion 4 and the shaft member 7 as in the illustrated example, the thigh portion 4 Since the possibility that the end portion 8 interferes with, for example, the body portion 2 is increased with the development of the above, it is particularly useful.
なお、腿部分４を関節部材３に回動可能に連結する手段として、上述した例では一自由度の軸部材７が用いられているが、関節部材３の中心軸線Ｘに対して腿部分４が屈伸可能であれば特に限定されず、例えばボールジョイントなどを用いることもできる。
In the above-described example, the shaft member 7 having one degree of freedom is used as a means for rotatably connecting the thigh portion 4 to the joint member 3, but the thigh portion 4 with respect to the central axis X of the joint member 3. If it can bend and stretch, it will not specifically limit, For example, a ball joint etc. can also be used.
以上、股関節を例に、本発明の人形体の関節構造を説明したが、上述した構成は、例えば肘関節、膝関節、肩関節、等の屈伸可能な関節に広く適用可能である。
As described above, the joint structure of the doll body of the present invention has been described taking the hip joint as an example, but the above-described configuration can be widely applied to joints that can bend and stretch, such as an elbow joint, a knee joint, and a shoulder joint.
