Description

本発明は、肘又は膝関節の動きをリアルにした人形玩具の肘部又は膝部の関節構造に関するものである。   The present invention relates to the joint structure of the elbow or knee of a doll toy that realistically moves the elbow or knee.

従来から、着せ替えタイプの人形玩具には、腕、脚等を人間の動きに合わせた関節を有するものが種々存在している。   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.

たとえば、肘関節については、図６（ａ）に示されるように、関節部材１１は、上腕部と前腕部とにそれぞれ嵌合する連結部１２、１３を外周面に備えた２つの円板体１４、１５の中心を、共通の連結部材１６に軸着したものが知られている。上記構成の関節部材１１によれば、上腕部と前腕部とそれぞれ一体的に結合している２つの円板体１４、１５が独立に回動自在になっている。肘部を曲げるとき、上腕部と前腕部とは２個の円板体１４、１５で回動するので、深く曲げることができるという利点を有するが、その反面、肘部を曲げる際、上腕部および前腕部のどちらも同時に回動してしまうため、上腕部および前腕部が２個所で曲がることができるから、同図（ｂ）のようになったり同図（ｃ）に示されるようになったりするので、肘の曲がり具合が決まらない。したがって、自然な状態にするには、いったん不自然な状態になった後に修正しなければならず、このため、ポーズ決めに手間取ってしまうという問題があった。   For example, for the elbow joint, as shown in FIG. 6 (a), the joint member 11 has two disc bodies each provided with connecting portions 12 and 13 fitted on the upper arm portion and the forearm portion on the outer peripheral surface, respectively. One in which the centers of 14 and 15 are attached to a common connecting member 16 is known. According to the joint member 11 having the above-described configuration, the two disk bodies 14 and 15 that are integrally coupled to the upper arm portion and the forearm portion are independently rotatable. When the elbow part is bent, the upper arm part and the forearm part are rotated by the two disc bodies 14 and 15, so that it can be bent deeply, but on the other hand, when the elbow part is bent, the upper arm part Since both the forearm part and the forearm part rotate at the same time, the upper arm part and the forearm part can be bent at two places, so that it becomes as shown in FIG. So the elbow bends are not determined. Therefore, in order to obtain a natural state, it has to be corrected after the unnatural state is reached. Therefore, there is a problem that it takes time to determine a pose.

本発明は上記問題点を解消し、簡単な構造によって、人間の肘又は膝関節の動きと同じような動きをリアルに実現することができる人形玩具の肘部又は膝部の関節構造を提供することをその課題とする。   The present invention provides an elbow or knee joint structure of a doll toy that can solve the above problems and can realize realistic movement similar to that of a human elbow or knee joint with a simple structure. That is the issue.

本発明に係る人形玩具の肘部又は膝部の関節構造は、上腕部又は大腿部と前腕部又は脛部とを関節部材を介して連結する、以下の要件を備えたことを特徴とする人形玩具の肘部又は膝部の関節構造。
（イ）上記関節部材は、上腕部又は大腿部と前腕部又は脛部とにそれぞれ嵌合する連結部を外周面に形成した２つの円板体の中心を、共通の連結部材に軸着したこと
（ロ）円板体の連結部を除く外周面には円弧部と円弧溝とが形成されていること
（ハ）一方の円板体の円弧溝はその連結部と反対側に形成され、他方の円板体の円弧溝はその連結部の軸心に対して側方に形成されていること
（ニ）上記２つの連結部を直線上に並べたときに一方の円板体の円弧溝に他方の円板体の外周面が嵌まり合うとともに、上記２つの連結部を最大限に折り曲げた状態にしたときに一方の円板体の外周面が他方の円板体の円弧溝に嵌まり合うように形成されていること The joint structure of the elbow part or knee part of the doll toy according to the present invention is characterized in that the upper arm part or the thigh part and the forearm part or the shin part are connected through a joint member and have the following requirements: The joint structure of the elbow or knee of a doll toy.
(B) The joint member is pivotally attached to the common connecting member at the center of the two disc bodies formed on the outer peripheral surface with connecting portions fitting respectively to the upper arm portion or the thigh portion and the forearm portion or the shin portion. (B) An arc portion and an arc groove are formed on the outer peripheral surface excluding the connecting portion of the disc body. (C) The arc groove of one disc body is formed on the opposite side of the connecting portion. The arc groove of the other disc body is formed laterally with respect to the axis of the connecting portion. (D) When the two connecting portions are arranged on a straight line, the arc of one disc body is formed. The outer peripheral surface of the other disc body fits into the groove, and the outer peripheral surface of one disc body becomes an arc groove of the other disc body when the two connecting portions are bent to the maximum. It is formed to fit

請求項１に係る発明によれば、上腕部又は大腿部と前腕部又は脛部とを関節部材で折り曲げると、まず一方の円板体の円弧部は他方の円板体の円弧溝に嵌まっているので回動できない。このため、他方の円板体がまず先に回動する。そして、他方の円板体の円弧溝が嵌まり合いを脱すると、今度は逆に、他方の円板体の円弧部は一方の円板体の円弧溝に嵌まり始めるので、他方の円板体は回動できなくなり、一方の円板体が回動することになる。したがって、肘又は膝を曲げるときは、２つの円板体は順次に回動し、同時に回動することはできないので、肘又は膝の曲がり具合が自然である。したがって、簡単な構造によって、人間の肘又は膝関節の動きと同じような動きをリアルに実現することができる   According to the first aspect of the present invention, when the upper arm part or the thigh part and the forearm part or the shin part are bent by the joint member, the arc part of one disk body is first fitted into the arc groove of the other disk body. Since it is stuck, it cannot rotate. For this reason, the other disk body first rotates first. And when the arc groove of the other disc body is removed from the fit, the arc portion of the other disc body starts to fit into the arc groove of the one disc body. The body can no longer rotate, and one disk body rotates. Therefore, when the elbow or knee is bent, the two disc bodies rotate sequentially and cannot rotate at the same time, so the elbow or knee bends naturally. Therefore, with a simple structure, it is possible to realize realistic movement similar to that of a human elbow or knee joint.

なお、２つの円板体の連結部を直線上に並べたときに一方の円板体の円弧溝に他方の円板体の外周面が嵌まり合う構成であるから、２つの円板体の連結部を近接するように配置することができるため、肘又は膝の関節部分がリアルになる。   In addition, since it is the structure which the outer peripheral surface of the other disc body fits in the circular-arc groove of one disc body when the connection part of two disc bodies is arranged on a straight line, Since the connecting portions can be arranged close to each other, the joint portion of the elbow or knee becomes realistic.

図１は人形玩具の肘部の概略を示す正面図で、符号１は上腕部を示し、２は前腕部を示す。上腕部１と前腕部２とは肘部の関節部材３を介して連結されている。   FIG. 1 is a front view showing an outline of an elbow part of a doll toy. Reference numeral 1 denotes an upper arm part, and 2 denotes a forearm part. The upper arm portion 1 and the forearm portion 2 are connected to each other via a joint member 3 at the elbow portion.

関節部材３は、上腕部１と前腕部２とにそれぞれ嵌合する連結部４を外周面に備えた２つの円板体５、６の中心の回動軸７を、共通の連結部材８に軸着したもので、円板体５、６の連結部４を除く外周面は円弧部９と１つの円弧溝１０とから構成されている。上腕部１と前腕部２の端部は適宜の手段で上記連結部４に連結される。   The joint member 3 has a rotating shaft 7 at the center of the two disc bodies 5 and 6 provided on the outer peripheral surface with connecting portions 4 fitted to the upper arm portion 1 and the forearm portion 2, respectively. The outer peripheral surface excluding the connecting portion 4 of the disk bodies 5 and 6 is composed of an arc portion 9 and one arc groove 10. End portions of the upper arm portion 1 and the forearm portion 2 are connected to the connecting portion 4 by an appropriate means.

なお、連結部４は図１に示した形状である必要はない。嵌め込み、係止などによって上腕部１又は前腕部２に連結可能な構造であればよい。   In addition, the connection part 4 does not need to be the shape shown in FIG. Any structure that can be connected to the upper arm portion 1 or the forearm portion 2 by fitting, locking, or the like may be used.

上腕部１の円板体５の円弧溝１０はその連結部４と反対側に形成され、前腕部２の円板体６の円弧溝１０はその連結部４の軸心に対して側方に形成されている。つまり、上記２つの連結部４を直線上に並べたときに上腕部１の円板体５の円弧溝１０に前腕部２の円板体６の外周面が嵌まり合うとともに、上記２つの連結部４を最大限に折り曲げた状態にしたときに上腕部１の円板体５の外周面が前腕部２の円板体６の円弧溝１０に嵌まり合うように形成されている。   The arc groove 10 of the disc body 5 of the upper arm 1 is formed on the side opposite to the connecting portion 4, and the arc groove 10 of the disc body 6 of the forearm 2 is lateral to the axis of the connecting portion 4. Is formed. That is, when the two connecting portions 4 are arranged in a straight line, the outer peripheral surface of the disc body 6 of the forearm portion 2 fits in the arc groove 10 of the disc body 5 of the upper arm portion 1 and the two connecting portions 4 The outer peripheral surface of the disc body 5 of the upper arm portion 1 is formed so as to fit into the arc groove 10 of the disc body 6 of the forearm portion 2 when the portion 4 is bent to the maximum extent.

次に、上記構成の関節構造の作動について説明する。上腕部１と前腕部２とを関節部材３で折り曲げると、まず折り曲げの初期には、図１に示されるように、上腕部１の円板体５の円弧部９は前腕部２の円板体６の円弧溝１０に嵌まっているので回動できない。このため、前腕部２の円板体６がまず回動軸７を中心に回動する。そして、図２のように、前腕部２の円板体６の円弧溝１０が嵌まり合いを脱すると、今度は逆に、図３に示されるように、上腕部１の円板体６の円弧部９は前腕部２の円板体５の円弧溝１０に嵌まり始めるので、前腕部２の円板体６は回動できなくなり、上腕部１の円板体５が回動することになる。上記２つの連結部４を最大限に折り曲げた状態にしたときに上腕部１の円板体５の外周面が前腕部２の円板体６の円弧溝１０に嵌まり合い、この状態で固定する。したがって、折り曲げ後に状態が変わることはない。   Next, the operation of the joint structure configured as described above will be described. When the upper arm portion 1 and the forearm portion 2 are bent by the joint member 3, first, at the initial stage of the bending, as shown in FIG. 1, the arc portion 9 of the disc body 5 of the upper arm portion 1 is the disc of the forearm portion 2. Since it fits into the circular groove 10 of the body 6, it cannot rotate. For this reason, the disc body 6 of the forearm portion 2 first rotates around the rotation shaft 7. Then, as shown in FIG. 2, when the arc groove 10 of the disc body 6 of the forearm portion 2 is disengaged, this time, conversely, as shown in FIG. 3, the disc body 6 of the upper arm portion 1 Since the arc portion 9 begins to fit into the arc groove 10 of the disc body 5 of the forearm portion 2, the disc body 6 of the forearm portion 2 cannot rotate, and the disc body 5 of the upper arm portion 1 rotates. Become. When the two connecting portions 4 are bent to the maximum extent, the outer peripheral surface of the disc body 5 of the upper arm portion 1 fits into the arc groove 10 of the disc body 6 of the forearm portion 2, and is fixed in this state. To do. Therefore, the state does not change after bending.

なお、上腕部１と前腕部２とを曲げた状態から元の真直の状態に戻すときは、図４および図５のように曲げればよい。   In addition, what is necessary is just to bend like FIG.4 and FIG.5 when returning from the state which bent the upper arm part 1 and the forearm part 2 to the original straight state.

このように、上腕部１と前腕部２とは２本の回動軸７によって関節部材３に連結されているが、肘を曲げるときは、２つの円板体５、６は順次に回動し、同時に回動することはできないので、肘の曲がり具合が自然であり、最後に曲げた状態が保持される。したがって、簡単な構造によって、人間の肘関節の動きと同じような動きをリアルに実現することができる。   As described above, the upper arm portion 1 and the forearm portion 2 are connected to the joint member 3 by the two rotation shafts 7, but when the elbow is bent, the two disk bodies 5 and 6 are sequentially rotated. However, since it cannot be rotated simultaneously, the bending state of the elbow is natural, and the bent state at the end is maintained. Therefore, a movement similar to that of a human elbow joint can be realized with a simple structure.

なお、２つの円板体５、６の連結部４を直線上に並べたときに一方の円板体５の円弧溝１０に他方の円板体６の外周面が嵌まり合う構成であるから、２つの円板体５、６の回動軸７を近接するように配置することができるため、肘又は膝の関節部分がリアルになる。   In addition, since the outer peripheral surface of the other disc body 6 fits in the circular arc groove 10 of one disc body 5 when the connection part 4 of the two disc bodies 5 and 6 is arranged on a straight line. Since the rotation shafts 7 of the two disc bodies 5 and 6 can be arranged close to each other, the elbow or knee joint portion becomes realistic.

なお、上腕部１と前腕部２は上述の例とは反対側の連結部４に連結するようにしてもよい。   In addition, you may make it connect the upper arm part 1 and the forearm part 2 to the connection part 4 on the opposite side to the above-mentioned example.

また、上記関節部材３は膝の関節部材３とし、大腿部と脛部とを連結するように構成してもよい。   The joint member 3 may be a knee joint member 3 and may be configured to connect the thigh and shin.
