【発明の属する技術分野】
本発明は、マネキン腕構造に関する。
【０００２】
【従来の技術】
従来のマネキン腕構造は、上腕体と胴体の肩部とが、折り曲げ可能な芯金で連結されたものが知られている（例えば、特許文献１参照）。

特開２００２−１５３３６３号公報
【０００４】
【発明が解決しようとする課題】
この従来のマネキン腕構造では、上腕体と胴体の肩部とが、離間した状態で連結されており、服を着させる際に、その窪み部に引っ掛かり手間が掛かる。また、上腕体は、上方から下方に渡って同じ径の棒体で形成されており、しかも、胴体の肩部から上腕体にかけての形状は、実際の人間の肩部の形状とは全く異なっているので、服を着させた場合の着装感が悪い。
【０００５】
そこで、本発明は、腕を揺動させて様々な姿勢にしても、肩部が、常に、実際の人間の肩部に近似した緩やかな弯曲状となり、服を着させた場合の着装感に優れるマネキン腕構造を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記の目的を達成するために、本発明に係るマネキン腕構造は、マネキンの胴体部の肩部と上腕体とを連結する肩部関節機構が、上記上腕体の上部に形成された嵌合凹球面部と、該嵌合凹球面部に摺動可能に嵌合する嵌合凸球面部を有すると共に上記胴体部の肩部の取付面に取着される関節雄部材と、該関節雄部材と上記上腕体とを連結する引張りバネ部材と、から構成され、上記関節雄部材の嵌合凸球面部には、スリットが、嵌合凸球面部の頂部を経由して、かつ上下方向に形成され、上記引張りバネ部材の一端側は、上記スリットを介して、上記関節雄部材の内部に形成された弯曲内周面に転動自在な回転軸部材に、枢結され、他端側は、上腕体の内部に取着されている。
【０００７】
また、マネキンの胴体部の肩部と上腕体とを連結する肩部関節機構が、上記上腕体の上部に形成された嵌合凹球面部と、該嵌合凹球面部に摺動可能に嵌合する嵌合凸球面部を有すると共に上記胴体部の肩部の取付面に取着される関節雄部材と、該関節雄部材と上記上腕体とを連結する引張りバネ部材と、から構成され、上記関節雄部材の嵌合凸球面部には、スリットが、嵌合凸球面部の頂部を経由して、かつ上下方向に形成され、上記引張りバネ部材の一端側は、上記スリットを介して、上記関節雄部材の内部に形成された弯曲内周面に摺動自在な低摩擦部材に、連結され、他端側は、上腕体の内部に取着されている。
【０００８】
また、上記引張りバネ部材が揺動する仮想揺動軸心は、上記取付面近傍乃至該取付面よりも胴体部の肩部側に存在するよう構成されている。
また、上記上腕体の上部の外側部は、上記嵌合凸球面部を包囲状の弯曲面をもって形成されている。
また、上記上腕体の上部の前後方向最大の横幅寸法が、上記上腕体の中間部位の前後方向の横幅寸法の １．１倍乃至 １．４倍に設定されている。
【０００９】
また、マネキンの上腕体と下腕体とを連結する肘関節機構が、上記上腕体の下端に形成され中空室を有する嵌合凸球面部と、上記下腕体の上部に形成され上記嵌合凸球面部に摺動可能に嵌合される嵌合凹球面部と、上記嵌合凸球面部と上記下腕体とを連結する引張りバネ部材と、から構成され、上記嵌合凸球面部には、スリットが、嵌合凸球面部の頂部を経由して、かつ左右方向に形成され、上記引張りバネ部材の一端側は、上記スリットを介して、上記嵌合凸球面部の中空室内部に形成された弯曲内周面に移動自在な誘導部材に、連結され、他端側は、下腕体の内部に取着されている。
【００１０】
【発明の実施の形態】
以下、実施の形態を示す図面に基づき、本発明を詳説する。
【００１１】
図１，図２，図３，図４に於て、マネキンＭの胴体部１の肩部２と上腕体３とを連結する肩部関節機構９は、上腕体３の上部４に形成された嵌合凹球面部５と、嵌合凹球面部５に摺動可能に嵌合する嵌合凸球面部６を有する関節雄部材１０と、関節雄部材１０と上腕体３とを連結する引張りバネ部材１１と、から構成され、関節雄部材１０は、胴体部１の肩部２に横向きに形成された取付面２ａに、取着される。
【００１２】
具体的には、関節雄部材１０の嵌合凸球面部６は、内部に中空部を有する略半球体形状で、内部に弯曲内周面１３が形成されている。また、嵌合凸球面部６には、スリット１２が、嵌合凸球面部６の頂部を経由して、かつ上下方向に形成されており、弯曲内周面１３上には、一対のガイドレール７，７が、スリット１２の両側に、かつ、スリット１２と一定間隔をもって沿うように、隆起状に並設されている。図３（ａ）は、（後述する）蓋体２５が取り外された状態を示しており、スリット１２に形成された空隙を、点々で示した。
【００１３】
そして、関節雄部材１０の弯曲内周面１３上には、回転軸部材１４が、一対のガイドレール７，７の間で、転動自在に配設され、引張りバネ部材１１の一端側１１ａは、スリット１２を介して、回転軸部材１４に枢結されている。また、上腕体３には、嵌合凹球面部５に上方開口３ｂを有する細長状孔部３ａが形成されており、引張りバネ部材１１の他端側１１ｂが、孔部３ａ内に配設された固定棒８に取着されている。
引張りバネ部材１１が揺動する仮想揺動軸心Ｌは、嵌合凸球面部６の仮想中心点２７を通り、取付面２ａ近傍乃至取付面２ａよりも胴体部１の肩部２側に存在するよう構成されている。
【００１４】
関節雄部材１０には、円形周端縁１０ａに沿うように、胴体部１の肩部２と関節雄部材１０を連結させる連結用蓋体２５が付設される。蓋体２５は、関節雄部材１０にネジ等で螺着される円形固定板２６と、胴体部１の取付面２ａに形成された取付孔部１ａに挿着される挿込部１６ａを有し円形固定板２６と摺接する取付部材１６と、を具備している。そして、弾発バネ１８により、取付部材１６は円形固定板２６に強く押圧され、円形固定板２６を、取付部材１６に対して、前後方向に揺動可能にするよう構成されている。
【００１５】
また、上腕体３の上部４の外側部４ａは、嵌合凸球面部６を包囲状に覆うように弯曲面をもって形成されている。また、上腕体３の上部４の前後方向最大の横幅寸法Ｗ４ が、上腕体３の中間部位１５の前後方向の横幅寸法Ｗ１５の １．１倍乃至 １．４倍に設定されている。この比率が １．１倍よりも小さいと、上腕体３の肩に該当する部位と、上腕体３の中間部位との差が小さく、また、１．４ 倍よりも大きいと、上記の差が大きいため、どちらの場合も、人体の腕の形状とかけ離れた形状になってしまい、マネキンＭに服を着させた場合の着装感が悪くなる。
【００１６】
また、関節雄部材１０の弯曲内周面１３には、（図１〜図３に示した）回転軸部材１４の代わりに、低摩擦部材２２が、一対のガイドレール７，７の間に、摺動自在に配設されてもよい。図５（ａ）は、要部拡大の側面図で、図５（ｂ）は、図５（ａ）のＡ−Ａ断面図であり、引張りバネ部材１１の一端側１１ａは、スリット１２を介して、低摩擦部材２２に形成された貫孔２２ａに挿入され、低摩擦部材２２の上部に付設される金属製等の係止部材２３に、係止される。低摩擦部材２２は、スリット１２よりも広い横幅を有し、プラスチック製等の滑らかな表て面を有する材質である。バネ部材１１の他端側１１ｂは、上腕体３の孔部３ａの内部に配設された固定棒８に取着されている。
【００１７】
次に、図１，図４，図６に於て、マネキンＭの上腕体３と下腕体１９とを連結する肘関節機構２０は、上腕体３の下端に形成され中空室３１を有する嵌合凸球面部３０と、下腕体１９の上部に形成される嵌合凹球面部２１と、嵌合凸球面部３０と下腕体１９とを連結する引張りバネ部材１１と、から構成される。嵌合凸球面部３０は、略球体形状を有し、嵌合凹球面部２１に摺動可能に嵌合されており、中空室３１内には、弯曲内周面１３が形成されている。嵌合凸球面部３０には、スリット１２が、嵌合凸球面部３０の頂部を経由して、かつ左右方向に形成されており、弯曲内周面１３上には、一対のガイドレール７，７が、スリット１２の両側に、かつ、スリット１２と一定間隔をもって沿うように、隆起状に並設されている。
【００１８】
そして、引張りバネ部材１１の一端側１１ａは、スリット１２を介して、嵌合凸球面部３０の弯曲内周面１３上に当接して移動自在な誘導部材２４に、連結され、他端側１１ｂは、下腕体１９の内部に取着される。図示では、誘導部材２４は、（図１〜図３にて説明した）回転軸部材１４であり、回転軸部材１４が、一対のガイドレール７，７の間に配設され、引張りバネ部材１１の一端側１１ａが、スリット１２を介して、回転軸部材１４に枢結されている。また、下腕体１９に、嵌合凹球面部２１に上方開口２９ａを有する細長状孔部２９が、形成され、引張りバネ部材１１の他端側１１ｂが、孔部２９の内部に配設された固定棒８に取着される。
【００１９】
また、図示省略するが、誘導部材２４を、回転軸部材１４の代わりに、（図５にて説明した）低摩擦部材２２として構成してもよい。
下腕体１９の外側上部１９ａは、肘を伸ばした状態で、嵌合凸球面部３０を包囲状とするように、形成されている。
【００２０】
次に、肩部関節機構９と肘関節機構２０の作用を説明する。まず、肩部関節機構９について、図１，図２に於て、上腕体３を横方向に揺動させると、回転軸部材１４が弯曲内周面１３上を転動して、引張りバネ部材１１は、仮想揺動軸心Ｌ廻りに揺動する。このとき、引張りバネ部材１１は、常に、（上述の）線２８と同じ方向へ引っ張られた状態で、かつ、一定長さに保たれている。
【００２１】
また、（図示省略するが、）上腕体３を横方向へ上げた状態にすると、上腕体３の上部４の外側部４ａと、胴体部１の肩部２とは、近接し、略同一弯曲状になる。また、上腕体３を下向きに下げた状態にすると、上腕体３の上部４の外側部４ａと、関節雄部材１０の嵌合凸球面部６の（上部の）一部と、胴体部１の肩部２とは、略同一弯曲状になる。
【００２２】
また、上腕体３を前後方向に揺動させると、関節雄部材１０に取り付けられた固定板２６が、取付部材１６に対して揺動し、上腕体３は、弾発バネ１８の弾発力により、自重で揺動しないように、姿勢を保持される。
また、図５に於ても、上腕体３を横方向に揺動させると、低摩擦部材２２が弯曲内周面１３上を摺動し、（図１，図２での説明と同様に）引張りバネ部材１１及び上腕体３は、仮想揺動軸心Ｌ廻りに回転する。
【００２３】
次に、肘関節機構２０については、図１，図６に於て、下腕体１９を左右方向に揺動させると、回転軸部材１４が弯曲内周面１３上を転動して、引張りバネ部材１１は、仮想揺動軸心Ｌ廻りに揺動する。そして、下腕体１９をどの位置に揺動しても、引張りバネ部材１１は、嵌合凸球面部３０の仮想中心点２７を通り下腕体１９に沿う線２８と、同じ方向に引っ張られた状態で、かつ、一定長さに保たれている。バネ部材１１の引張り力により、嵌合凸球面部３０が下腕体１９の嵌合凹球面部２１に強く押圧され、下腕体１９は、自重で揺動しないように保持される。
【００２４】
図１〜図３に示したように、肩部関節機構９に於て、引張りバネ部材１１の一端側１１ａが、弯曲内周面１３上を転動する回転軸部材１４に枢結されて構成されているので、引張りバネ部材１１及び上腕体３の仮想揺動軸心Ｌを、胴体部１側に位置するように構成することが可能である。よって、揺動中心軸を関節雄部材１０の内部に設ける必要がなく、嵌合凸球面部６を緩やかな弯曲状にすることができるので、上腕体３を横方向へ上げた状態では、上腕体３の上部４の外側部４ａと、胴体部１の肩部２とは近接して、略同一弯曲状になり、また、上腕体３を下向きに下げた状態では、上腕体３の上部４の外側部４ａと、関節雄部材１０の嵌合凸球面部６の（上部の）一部と、胴体部１の肩部２とは、略同一弯曲状になる。即ち、上腕体３をどの姿勢に揺動させても、実際の人間の肩部に近い形状となり、服を着させた時の着装感がよい。
【００２５】
また、上腕体３をどの位置に揺動しても、バネ部材１１は、常に同じ長さに引っ張られた状態に保たれて、関節雄部材１０の嵌合凸球面部６を上腕体３の嵌合凹球面部５に強く押圧するので、上腕体３は、その自重により不用意に揺動することがなく、同じ姿勢に保持される。また、図５に示したように、バネ部材１１の一端側１１ａが低摩擦部材２２に連結された場合でも、弯曲内周面１３上を滑らかに摺動するので、容易に上腕体３を揺動させることができ、しかも、上腕体３を、不用意に揺動することなく、同じ姿勢に保持できる。
【００２６】
また、図１，図４，図６に示したように、肘関節機構２０に於ても、（肩部関節機構９と同様に、）引張りバネ部材１１及び下腕体１９の揺動中心軸を、嵌合凸球面部３０の内部に設ける必要がないので、上腕体３の嵌合凸球面部３０を緩やかにすることも可能であり、下腕体１９の外側上部１９ａを滑らかな弯曲状にする等の形状の自由度も増し、好都合である。
【００２７】

（請求項１，２，３によれば、）引張りバネ部材１１及び上腕体３の揺動中心軸を関節雄部材１０の内部に設ける必要がなく、嵌合凸球面部６を緩やかな弯曲状にすることができるので、上腕体３を横方向へ上げた状態では、上腕体３の上部４の外側部４ａと、胴体部１の肩部２とは近接して、略同一弯曲状の肩部を形成し、また、上腕体３を下向きに下げた状態では、上腕体３の上部４の外側部４ａと、関節雄部材１０の嵌合凸球面部６の（上部の）一部と、胴体部１の肩部２とは、略同一弯曲状の肩部を形成する。即ち、上腕体３をどの姿勢に揺動させても、実際の人間の肩部に近い形状となり、服を着させた時の着装感がよい。

[0020]
Next, the operation of the shoulder joint mechanism 9 and the elbow joint mechanism 20 will be described. First, regarding the shoulder joint mechanism 9, when the upper arm 3 is swung laterally in FIGS. 1 and 2, the rotary shaft member 14 rolls on the curved inner peripheral surface 13, and the tension spring member 11 swings around the virtual swing axis L. At this time, the tension spring member 11 is always pulled in the same direction as the line 28 (described above) and is maintained at a certain length.
[0021]
When the upper arm 3 is raised in the lateral direction (not shown), the outer portion 4a of the upper portion 4 of the upper arm 3 and the shoulder 2 of the trunk portion 1 are close to each other and have substantially the same curvature. It becomes a shape. When the upper arm 3 is lowered downward, the outer portion 4 a of the upper portion 4 of the upper arm 3, a part (upper portion) of the fitting convex spherical portion 6 of the joint male member 10, and the body portion 1 The shoulder portion 2 has substantially the same curved shape.
[0022]
When the upper arm 3 is swung back and forth, the fixing plate 26 attached to the male joint member 10 is swung with respect to the mounting member 16, and the upper arm 3 is subjected to the elastic force of the elastic spring 18. Thus, the posture is held so as not to swing by its own weight.
Also in FIG. 5, when the upper arm 3 is swung in the lateral direction, the low friction member 22 slides on the curved inner peripheral surface 13 (similar to the description in FIGS. 1 and 2). The tension spring member 11 and the upper arm body 3 rotate around the virtual swing axis L.
[0023]
Next, regarding the elbow joint mechanism 20, in FIGS. 1 and 6, when the lower arm body 19 is swung in the left-right direction, the rotating shaft member 14 rolls on the curved inner peripheral surface 13 and pulls. The spring member 11 swings around the virtual swing axis L. Even if the lower arm body 19 is swung to any position, the tension spring member 11 is pulled in the same direction as the line 28 passing through the virtual center point 27 of the fitting convex spherical surface portion 30 and along the lower arm body 19. And kept at a certain length. The fitting convex spherical surface portion 30 is strongly pressed against the fitting concave spherical surface portion 21 of the lower arm body 19 by the tensile force of the spring member 11, and the lower arm body 19 is held so as not to swing by its own weight.
[0024]
As shown in FIGS. 1 to 3, in the shoulder joint mechanism 9, one end side 11 a of the tension spring member 11 is pivotally connected to a rotating shaft member 14 that rolls on the curved inner peripheral surface 13.

That is, no matter which posture the upper arm body 3 is swung to, it has a shape close to the actual human shoulder, and the wearing feeling when wearing clothes is good.
[0025]
Further, no matter where the upper arm 3 is swung, the spring member 11 is always kept in the state of being pulled to the same length, and the fitting convex spherical surface portion 6 of the joint male member 10 is moved to the upper arm 3. Since the fitting concave spherical surface portion 5 is strongly pressed, the upper arm body 3 is not inadvertently swung by its own weight and is held in the same posture. Further, as shown in FIG. 5, even when the one end side 11a of the spring member 11 is connected to the low friction member 22, the upper arm body 3 is easily shaken because it smoothly slides on the curved inner peripheral surface 13. In addition, the upper arm 3 can be held in the same posture without swinging carelessly.
[0026]
As shown in FIGS. 1, 4, and 6, in the elbow joint mechanism 20, as well as the shoulder joint mechanism 9, the swinging central axis of the tension spring member 11 and the lower arm body 19 is used. Since the fitting convex spherical surface 30 of the upper arm 3 can be loosened, the outer upper portion 19a of the lower arm 19 can be smoothly curved.
