【０００７】
また、前記一対の掛杆２から突出する夫々の突出部２Ａの突出度を、この突出部２Ａの側部同士が互いに近接若しくは当接する突出度に設定して、この突出部２Ａの側部同志が互いに近接若しくは当接することによって前記取付部１上に環状の前記支承環部３が形成されるように構成したことを特徴とする請求項２記載の連結具に係るものである。
【０００８】
また、前記一対の掛杆２は、連動機構５を介して一方の回動作動に他方が連動回動するように構成すると共に、いずれか一方の掛杆２の回動移動によって一対の掛杆２の前記突出部２Ａ同士が互いに接近回動し、且つ突出部２Ａ同士が互いに離反回動する前記連動機構５を構成したことを特徴とする請求項２，３のいずれか１項に記載の連結具に係るものである。

【００１１】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して簡単に説明する。
【００１２】
常態では、一方の掛杆２の突出部２Ａが他方の掛杆２に近接若しくは当接するように一方の掛杆２が付勢機構４により回動付勢されるか、或いは突出部２Ａ同士が近接若しくは当接するように一対の掛杆２が付勢機構４により回動付勢されて、取付部１上にはこの掛杆２並びに突出部２Ａと取付部１の上面とによって環状の支承環部３が形成されている。
【００１３】
この付勢機構４に抗して突出部２Ａを他方の掛杆２から離反するように一方の掛杆２を回動するか、或いは付勢機構４に抗して突出部２Ａ同士を離反するように一対の掛杆２を回動すると、取付部１上に形成された支承環部３が開放し、この開放部分から取付部１上にロープ20などを通したり、掛杆２や突出部２Ａに輪状にしたロープやフック24などを連結したりすることができる。
【００１４】
その後、回動させた掛杆２から手を離せば、この掛杆２が付勢機構４により自動的に戻り回動して、一方の掛杆２の突出部２Ａが他方の掛杆２に近接若しくは当接するか、或いは突出部２Ａ同士が近接若しくは当接して、取付部１上に環状の前記支承環部３が形成され、この支承環部３が形成された状態が付勢機構４によって維持されることになるため、この支承環部３に通したロープ20や、掛杆２や突出部２Ａに掛止したフック24などが抜け外れてしまうことがない。
【００１５】
従って、単に掛杆２を付勢機構４に抗して回動操作するだけで支承環部３を開放してロープ20やフック24などを連結したり外したりすることができるため着脱作業が極めて容易にでき、しかも手を離せば付勢機構４により自動的に支承環部３が形成された状態に復帰して維持されることになるので、連結保持したロープ20やフック24などが抜け外れることも防止されるなど信頼性のある極めて実用性に秀れた画期的な連結具となる。
【００１６】
また、例えば本連結具を、実施例のように親綱20の途中部を通して保持するための連結具として使用した場合には、適所に予め架設状態にして張設された親綱20を前記支承環部３に通す場合であっても、この支承環部３が例えば図６に示すように対向する掛杆２の略中間位置で開放するため、この親綱20を緩めることなく少し引っ張るようにしながら上記のような簡易な作業によって支承環部３内に親綱20を配設する（通す）ことができる。
【００１７】
また、例えば、支承環部３に親綱20を一本通した後で再度二本・三本と親綱20を通したいことがある。この際、例えば支承環部を開放するに当たって、予め通してある親綱が邪魔になるような構造であると、この通してある親綱を緩めてから支承環部を開放して他の親綱を通すようにしなければならないが、本発明においては、支承環部３を開放する際に予め通してある親綱20が水平回動する掛杆２（突出部２Ａ）に対して全く邪魔とならないので、この親綱20の追加通し作業を極めて容易に行うことができる。
【００１８】
また、例えば、前記一対の掛杆２から突出する夫々の突出部２Ａの突出度を、この突出部２Ａの側部同士が互いに近接若しくは当接する突出度に設定して、この突出部２Ａの側部同志が互いに近接若しくは当接することによって前記取付部１上に環状の前記支承環部３が形成されるように構成すれば、前記支承環部３が確実な環状を呈することになるので、この支承環部３に連結保持したロープ20やフック24などが抜け外れることが確実に防止されることになり、一層信頼性が向上する。
【００１９】
また、例えば、前記一対の掛杆２は、連動機構５を介して一方の回動作動に他方が連動回動するように構成すると共に、いずれか一方の掛杆２の回動移動によって一対の掛杆２の前記突出部２Ａ同士が互いに接近回動し、且つ突出部２Ａ同士が互いに離反回動する前記連動機構５を構成すれば、いずれか一方の掛杆２を回動操作するだけで双方の掛杆２（突出部２Ａ）が回動して支承環部３が広く開放し、且つ手を離せば双方の掛杆２が自動的に支承環部３を形成するように戻り回動作動することになるので、一層操作性に秀れ実用的となる。
【００２０】
【実施例】
本発明の具体的な実施例について図面に基づいて説明する。
【００２１】
本実施例は、取付部１の上面に一対の掛杆２を所定間隔を置いて立設し、この一対の掛杆２に夫々対向方向に向かって突出する突出部２Ａを設けて、この突出部２Ａ同士が近接若しくは当接することによって前記取付部１上に環状の支承環部３が形成されるように構成している。
【００２２】
具体的に説明すると、本実施例の取付部１は、図４，図５に示すような断面コ字型の板材により構成し、このコ字型板材の中間板部を取付部１の上面としている。
【００２３】
掛杆２は、図４に示すように、略Ｕ（Ｊ）型を呈する杆材により構成し、二体のこの掛杆２の夫々の一端部を取付部１の上面に所定間隔を置いて付設することで、取付部１上に対設状態にして立設状態に設けている。また、この掛杆２他端側（上方部）の側方へ突出する部分を前記突出部２Ａとし、この突出部２Ａ同士が夫々の掛杆２の対向方向に向かって突出するように構成している。
【００２４】
また、この一対の掛杆２から突出する夫々の突出部２Ａは、この突出部２Ａの側部同士が互いに突き合わせ状態で当接重合するように突出度を設定構成している。
【００２５】
更に詳しく説明すると、この突出部２Ａを備えた一対のＵ型掛杆２は、図５に示すように正面から見て夫々の全部が丁度重なり合うように構成し、これにより前記取付部１上に前記支承環部３を形成するように構成している。
【００２６】
本実施例では、この一対の掛杆２を取付部１に対して水平回動可能に設け、前記突出部２Ａ同士を回動離反させることで支承環部３が開放するように構成している。
【００２７】
具体的に説明すると、図４，図５に示すように、取付部１の上面左右に軸受筒部６を立設状態に突設すると共に、この取付部１の下方の遊離板部間に架設状態にして取付板部７を設け、この取付板部７には前記軸受筒部６と位置を合わせるようにして合わせ孔８を形成している。
【００２８】
そして、この軸受筒部６と合わせ孔８とに掛杆２の一端側を嵌挿し、合わせ孔８を介して取付板部７より下方に突出している掛杆２の一端部（螺子杆部）に螺着具９（ナット）を螺着することで掛杆２を取付部１から上方へ抜け止め状態とし、且つ軸受筒部６に嵌挿した掛杆２の一端部を支軸としてこの掛杆２が取付部１の上面に対して水平回動自在となるように設けている。図中符号11は座金である。
【００２９】
また、本実施例では、使用状態の一例として、図１に示すように立設状態に設置される筒状の親綱支柱16に取付部１を取付設置した場合を示している。
【００３０】
この取付部１の親綱支柱16に対する固定手段17について説明すると、親綱支柱16と取付部１の左右の遊離板部とに連通状態にしてボルト通し孔18を設けると共に、遊離板部側のこのボルト通し孔18を螺子孔とし、このボルト通し孔18に前記親綱支柱16の外方から座金11を介しボルト19を挿通して遊離板部側のボルト通し孔18に螺着することで、前記取付部１が親綱支柱16に対して嵌脱不能状態に固定されるように構成している。
【００３１】
以下、更に具体的に説明すると、図１〜図３は第一実施例、図４〜図６は第二実施例を示している。
【００３２】
第一実施例について説明する。
【００３３】
本実施例は、一対の掛杆２が別々に回動作動するように構成した場合である。
【００３４】
具体的に説明すると、夫々の掛杆２には、図３に示すように棒状の回動規制体23が水平方向に突設され、この回動規制体23が前記親綱支柱16の内壁面に当接係止することで、これ以上掛杆２が開き方向へ回動できなくなる構成としている。
【００３５】
また、本実施例では、この掛杆２と取付部１とに前記支承環部３が形成された状態を維持するように掛杆２を回動付勢する付勢機構４を設けている。
【００３６】
付勢機構４について具体的に説明すると、夫々の掛杆２にねじりバネを採用した弾性体15を被嵌装着し、このねじりバネ15の一端を回動規制体23に係止し、他端を取付部１の遊離板部内面に係止することで、掛杆２に支承環部３が形成された状態を維持するように回動付勢力が付与される構成としている。
【００３７】
次に、本実施例の具体的な使用方法について説明する。
【００３８】
例えば、図２に示すように、付勢機構４に抗して一方の突出部２Ａを他方の突出部２Ａから離反するように一方の掛杆２を回動操作する。そして、この離れた突出部２Ａ間にロープ20（親綱）を入れ、そのまま引き続いて取付部１上に親綱20を押し入れると、他方の掛杆２も親綱20によって押し開かれて支承環部３が開放し、掛杆２間に親綱20が通される。従って、このようにして親綱通し作業を極めて容易に行うことができるし、この作業は適所に予め架設状態にして張設された親綱20を支承環部３に通す場合であっても、この支承環部３が図２に示すように対向する掛杆２の略中間上部位置で開放するため、親綱20を緩めることなく支承環部３の上方部へ引っ張ってきて上記のようにして簡易に支承環部３内に親綱20を配設する（通す）ことができる。
【００３９】
また、この際、掛杆２や突出部２Ａに、例えば第二実施例の図５に示したようにフック24や輪状のロープなどを連結することもできる。
【００４０】
その後、回動させた掛杆２から手を離せば、この掛杆２が付勢機構４により自動的に戻り回動して突出部２Ａ同士が当接し、取付部１上に環状の前記支承環部３が形成され、この支承環部３が形成された状態が付勢機構４によって維持され。（図１参照）従って、この支承環部３に通したロープ20や、掛杆２や突出部２Ａに掛止したフック24などが抜け外れてしまうことがない。
【００４１】
また、本実施例では、前記突出部２Ａ同士が全部ぴったりと重なり合うように当接して支承環部３を形成するから、この支承環部３を構成する掛杆２並びに突出部２Ａは、どの部分においても二重に重合した構成となり、これによりフック24などに対して極めて強固な連結強度を発揮することになり、安全性に秀れ非常に信頼性のある構造となる。
【００４２】
第二実施例について説明する。
【００４３】
本実施例は、前記一対の掛杆２は、連動機構５を介して一方の回動作動に他方が連動回動するように構成した場合である。
【００４４】
連動機構５について具体的に説明すると、夫々の掛杆２の途中部に、前記取付板部７の上方に位置するようにして連動体10を固定し、この連動体10が掛杆２と共に連動作動するように構成している。図中符号21は掛杆２に対して連動体10を固定するための固定孔である。
【００４５】
また、この掛杆２に固定された前記連動体10は、図４，図６に示すように前記突出部２Ａの突出方向と同じ方向に延長突出する形状に形成し、この連動体10の突出端部寄り位置に嵌合孔14を形成している。
【００４６】
一方、取付板部７上面の略中間部に、円板状の回転体12を枢着軸22により水平回動自在に枢着し、この回転体12の対向する二箇所の縁部には連結突片13を形成し、この連結突片13を前記夫々の掛杆２の嵌合孔14に嵌合係止している。
【００４７】
従って、一対の掛杆２のうちのいずれか一方を回動操作すると、これに伴って回転体12も回動作動して他方の掛杆２も回動作動する構成としている。
【００４８】
また、このように回転体12を一対の掛杆２間に介在しているため、この回転体12の回動作動によって双方の掛杆２は互いに逆方向に回動作動することになり、これによりいずれか一方の掛杆２の一方向への回動移動によって一対の掛杆２の前記突出部２Ａ同士が互いに接近回動し、且つ逆方向への回動移動によって突出部２Ａ同士が互いに離反回動する構造としている。
【００４９】
また、本実施例では、この掛杆２と取付部１とに前記支承環部３が形成された状態を維持するように掛杆２を回動付勢する付勢機構４を設けている。
【００５０】
付勢機構４について具体的に説明すると、一方の掛杆２の一端部に、前記第一実施例と同様にねじりバネを採用した弾性体15を被嵌装着し、このねじりバネ15の一端を前記連動体10に係止し、他端を取付部１の遊離板部内面に係止することで、掛杆２に支承環部３が形成された状態を維持するように回動付勢力が付与される構成としている。
【００５１】
尚、この付勢機構４として前記第一実施例と同様に双方の掛杆２に弾性体15を設けても良いが、本実施例の場合には双方の掛杆２が連動作動するので、一方の掛杆２に弾性体15を設けるだけで十分に前記作用効果が得られるし、この方が弾性体15を一つ使用するだけで良いため安価に構成できる。
【００５２】
次に、本実施例の具体的な使用方法について説明する。
【００５３】
図４に示すように、付勢機構４に抗して突出部２Ａ同士を離反するように一対の掛杆２を回動操作すると、取付部１上に形成された支承環部３の上部の真中部分が開放する。そして、単にこの開放部分から取付部１上にロープ20（親綱）を降ろすことにより掛杆２間に通すことができる。従って、このようにして親綱通し作業を極めて容易に行うことができるし、この作業は適所に予め架設状態にして張設された親綱20を支承環部３に通す場合であっても、支承環部３が図６に示すように対向する掛杆２の真中上部位置で開放するため、親綱20を緩めることなく支承環部３の上方部へ引っ張ってきて上記のようにして簡易に支承環部３内に親綱20を配設する（通す）ことができる。
【００５４】
その後、回動させた掛杆２から手を離せば、この掛杆２が付勢機構４により自動的に戻り回動して突出部２Ａ同士が当接し、取付部１上に環状の前記支承環部３が形成され、この支承環部３が形成された状態が付勢機構４によって維持される。従って、この支承環部３に通したロープ20は抜け外れてしまうことがない。
【００５５】
また、勿論、前記第一実施例と同様に、掛杆２や突出部２Ａにフック24や輪状のロープなどを連結することもできる。
【００５６】
尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。
【００５７】
また、本実施例では、一対の掛杆２の双方を略同一形状のものとして、この双方の掛杆２が回動するように構成した場合を示したが、一対の掛杆２のいずれか一方だけが回動するように構成しても良く、またこの場合には回動作動する方の掛杆２だけに突出部２Ａを形成する構成としても良い。
【００５８】
また、本実施例では、親綱支柱16に取り付けして親綱保持具として使用した場合を示したが、これに用途を限定するものではなく、その他の様々な用途に適用可能であり、この用途に応じて取付部１の構造も適宜設計変更可能である。
【００５９】
【発明の効果】
本発明は上述のように構成したから、単に掛杆を付勢機構に抗して回動操作するだけで支承環部を開放してロープやフックなどを連結したり外したりすることができるため着脱作業が極めて容易にでき、しかも手を離せば付勢機構により自動的に支承環部が形成された状態に復帰して維持されることになるので、連結保持したロープやフックなどが抜け外れることも防止されるなど信頼性のある極めて実用性に秀れた画期的な連結具となる。
【００６０】
また、本発明は、掛杆を略Ｌ型若しくは略Ｕ型に形成することで側方に突出する突出部を備えた掛杆に構成したから、突出部を備えた掛杆を簡易構成にして容易に設計実現可能となる一層実用性に秀れた構成の連結具となる。
【００６１】
また、請求項３記載の発明においては、突出部の側部同士が互いに近接若しくは当接して前記支承環部が確実な環状を呈することになるので、この支承環部に連結保持したロープやフックなどが抜け外れることが確実に防止される極めて実用性に秀れた連結具となる。
【００６２】
また、請求項４記載の発明においては、いずれか一方の掛杆を回動操作するだけで双方の掛杆（突出部）が回動して支承環部が広く開放し、且つ手を離せば双方の掛杆が自動的に支承環部を形成するように戻り回動作動することになるので、一層操作性に秀れ、実用性に秀れた連結具となる。
【００６３】
また、請求項５記載の発明おいては、ロープやフックなどを確実に抜け止め状態に保持できる前記支承環部が形成されることになる一層実用性に秀れた連結具となる。
【００６４】
また、請求項６記載の発明おいては、略同一形状の突出部同士が重なり合うように当接して前記支承環部を形成するから、この支承環部を構成する掛杆並びに突出部は、どの部分においても二重に重合しているためにフック連結時などには極めて強固な連結強度を発揮することになり、一層信頼性があり安全性に秀れた連結具となる。

As a result, the rope 20 passed through the support ring 3 and the hook 24 hooked to the hook 2 and the protrusion 2A will not come off.
[0015]
Therefore, simply by rotating the hook 2 against the urging mechanism 4, the bearing ring 3 can be opened and the rope 20 and the hook 24 can be connected and disconnected, so that the attaching / detaching work is extremely difficult. If the hand is released, the biasing mechanism 4 automatically returns to and maintains the state in which the support ring portion 3 is formed, so that the rope 20 and the hook 24 that are connected and held can be removed. This is an epoch-making connector that is highly reliable and extremely practical.
[0016]
In addition, for example, when this connector is used as a connector for holding the middle part of the master rope 20 as in the embodiment, the master rope 20 stretched in advance in a proper position is attached to the support. Even when passing through the ring portion 3, the support ring portion 3 opens at a substantially intermediate position between the opposite hooks 2 as shown in FIG. 6, for example, so that the master rope 20 is pulled slightly without loosening. However, the master rope 20 can be arranged (passed) in the bearing ring portion 3 by the simple operation as described above.
[0017]
Also, for example, after passing one master rope 20 through the support ring 3, there are times when it is desired to pass two or three master ropes 20 again. At this time, for example, when opening the support ring part, if the structure is such that the parent rope that has been passed in advance becomes an obstacle, the support ring part is opened after the parent rope that has been passed through is released and another parent rope is opened. However, in the present invention, when the support ring portion 3 is opened, the master rope 20 passed through in advance does not interfere with the hanging hook 2 (projecting portion 2A) that rotates horizontally. Therefore, this additional work of the master rope 20 can be performed very easily.
[0018]
Further, for example, the projecting degree of each projecting part 2A projecting from the pair of hooks 2 is set to a projecting degree in which the side parts of the projecting part 2A are close to or in contact with each other , and the projecting part 2A side If the ring-shaped support ring part 3 is formed on the mounting part 1 by the parts coming close to or in contact with each other , the support ring part 3 exhibits a reliable ring shape. The rope 20 and the hook 24 connected and held to the support ring portion 3 are surely prevented from coming off and the reliability is further improved.
[0019]
In addition, for example, the pair of hooks 2 are configured such that one of the hooks 2 is rotated in conjunction with the rotation of the other via the interlocking mechanism 5, and the pair of hooks 2 are rotated by one of the hooks 2. If the interlocking mechanism 5 is configured such that the protrusions 2A of the hanging hook 2 rotate close to each other and the protrusions 2A rotate away from each other, only one of the hanging hooks 2 is rotated. Both hooks 2 (protruding part 2A) rotate so that the support ring part 3 opens widely, and when the hands are released, both hooks 2 automatically form the support ring part 3 so as to return. Because it will move, it will be more excellent in operability and practical.

[0031]
More specifically, FIGS. 1 to 3 show a first embodiment, and FIGS. 4 to 6 show a second embodiment.
[0032]
A first embodiment will be described.
[0033]
In this embodiment, the pair of hooks 2 are configured to rotate separately.
[0034]
More specifically, as shown in FIG. 3, each hook 2 is provided with a bar-shaped rotation restricting body 23 that protrudes in the horizontal direction, and this rotation restricting body 23 is the inner wall surface of the main rope support 16. The hook 2 can no longer be rotated in the opening direction by being in contact with and locked to.
[0035]
Further, in this embodiment, an urging mechanism 4 for rotating and urging the hook 2 is provided so as to maintain the state in which the bearing ring portion 3 is formed on the hook 2 and the attachment portion 1.
[0036]
The urging mechanism 4 will be described in detail. An elastic body 15 using a torsion spring is fitted and attached to each hook 2, and one end of the torsion spring 15 is locked to the rotation restricting body 23 and the other end. Is locked to the inner surface of the free plate portion of the mounting portion 1 so that a rotational biasing force is applied so as to maintain the state in which the support ring portion 3 is formed on the hook 2.
[0037]
Next, a specific method of using the present embodiment will be described.
[0038]
For example, as shown in FIG. 2, one hook 2 is rotated so as to separate one protrusion 2 A from the other protrusion 2 A against the biasing mechanism 4. Then, when the rope 20 (master rope) is inserted between the separated projecting parts 2A and the master rope 20 is subsequently pushed onto the mounting portion 1, the other hook 2 is pushed open by the master rope 20 and supported. The ring part 3 is opened, and the master rope 20 is passed between the hanging hooks 2. Therefore, it is possible to carry out the master rope work very easily in this way, and even if this work is a case where the master rope 20 stretched in advance in a proper position is passed through the support ring portion 3, As shown in FIG. 2, the support ring part 3 is opened at a substantially middle upper position of the opposite hooks 2 so that the main rope 20 can be pulled upward without loosening the master rope 20 as described above. The master rope 20 can be easily disposed (passed) in the bearing ring portion 3.
[0039]
At this time, for example, as shown in FIG. 5 of the second embodiment, a hook 24, a ring-shaped rope, or the like can be connected to the hanging hook 2 or the protruding portion 2A.
[0040]
Thereafter, when the hand is released from the pivoted hook 2, the hook 2 is automatically returned and rotated by the urging mechanism 4 so that the projecting portions 2 A come into contact with each other, and the annular support on the attachment portion 1. The ring portion 3 is formed, and the state where the support ring portion 3 is formed is maintained by the biasing mechanism 4. (See FIG. 1) Accordingly, the rope 20 passed through the support ring portion 3, the hook 24 hooked to the hook 2 and the protruding portion 2A, etc. will not come off.
[0041]
Further, in this embodiment, since the projecting portions 2A are in contact with each other so as to completely overlap with each other to form the support ring portion 3, the hook 2 and the projecting portion 2A constituting the support ring portion 3 are arranged in any part. In this case, the structure is double-polymerized, thereby exhibiting extremely strong connection strength with respect to the hook 24 and the like, resulting in a highly reliable structure with excellent safety.
[0042]
A second embodiment will be described.
[0043]
In the present embodiment, the pair of hooks 2 are configured such that one of the pair of hanging hooks 2 is interlocked and rotated via the interlocking mechanism 5.
[0044]
The interlocking mechanism 5 will be described in detail. The interlocking body 10 is fixed to the middle part of each hanging hook 2 so as to be positioned above the mounting plate 7, and the interlocking body 10 is interlocked with the hanging hook 2. It is configured to operate. Reference numeral 21 in the figure is a fixing hole for fixing the interlocking body 10 to the hanging hook 2.
[0045]
Further, the interlocking body 10 fixed to the hook 2 is formed in a shape extending and projecting in the same direction as the protruding direction of the protruding portion 2A as shown in FIGS. A fitting hole 14 is formed near the end.
[0046]
On the other hand, a disk-shaped rotating body 12 is pivotally mounted on a substantially intermediate portion on the upper surface of the mounting plate 7 by a pivoting shaft 22 so as to be horizontally rotatable, and is connected to two opposing edges of the rotating body 12. A protruding piece 13 is formed, and the connecting protruding piece 13 is fitted and locked in the fitting hole 14 of each hook 2.
[0047]
Accordingly, when any one of the pair of hooks 2 is rotated, the rotating body 12 is also rotated and the other hook 2 is also rotated.
[0048]
Further, since the rotating body 12 is interposed between the pair of hooks 2 as described above, the rotating action of the rotating body 12 causes both the hooks 2 to rotate in opposite directions. Accordingly, the protrusions 2A of the pair of hooks 2 are moved closer to each other by the rotational movement of one of the hooks 2 in one direction, and the protrusions 2A are mutually rotated by the rotational movement of the pair of hooks 2 in the opposite direction. It is structured to rotate away.
[0049]
Further, in this embodiment, an urging mechanism 4 for rotating and urging the hook 2 is provided so as to maintain the state in which the bearing ring portion 3 is formed on the hook 2 and the attachment portion 1.
[0050]
The urging mechanism 4 will be described in detail. One end of one hook 2 is fitted with an elastic body 15 that employs a torsion spring in the same manner as in the first embodiment, and one end of the torsion spring 15 is attached. By engaging with the interlocking body 10 and engaging the other end with the inner surface of the free plate portion of the mounting portion 1, the rotational biasing force is maintained so as to maintain the state in which the support ring portion 3 is formed on the hook 2. The configuration is given.
[0051]
As the urging mechanism 4, both the hooks 2 may be provided with an elastic body 15 as in the first embodiment. However, in the case of this embodiment, both the hooks 2 operate in conjunction with each other. The above-described effect can be obtained sufficiently by simply providing the elastic body 15 on one of the hanging hooks 2, and since only one elastic body 15 needs to be used in this way, it can be constructed inexpensively.
[0052]
Next, a specific method of using the present embodiment will be described.
[0053]
As shown in FIG. 4, when the pair of hooks 2 are rotated so as to separate the protrusions 2 A against the urging mechanism 4, the upper part of the support ring 3 formed on the attachment part 1 is operated. The middle part opens. Then, the rope 20 (master rope) can be simply lowered from the open portion onto the attachment portion 1 and can be passed between the hooks 2. Therefore, it is possible to carry out the master rope work very easily in this way, and even if this work is a case where the master rope 20 stretched in advance in a proper position is passed through the support ring portion 3, Since the support ring part 3 is opened at the middle upper position of the opposite hanging hook 2 as shown in FIG. 6, it can be easily pulled as described above by pulling the upper part of the support ring part 3 without loosening the master rope 20. The master rope 20 can be disposed (passed) in the bearing ring portion 3.
[0054]
Thereafter, when the hand is released from the pivoted hook 2, the hook 2 is automatically returned and rotated by the urging mechanism 4 so that the projecting portions 2 A come into contact with each other, and the annular support on the attachment portion 1. The ring portion 3 is formed, and the state where the support ring portion 3 is formed is maintained by the biasing mechanism 4. Accordingly, the rope 20 passed through the bearing ring portion 3 will not come off.
[0055]
Of course, as in the first embodiment, a hook 24, a ring-shaped rope, or the like can be connected to the hook 2 or the protruding portion 2A.
[0056]
Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
[0057]
In the present embodiment, both the pair of hanging hooks 2 have substantially the same shape, and both the hanging hooks 2 are configured to rotate. However, either one of the pair of hanging hooks 2 is shown. Only one side may be configured to rotate, and in this case, the protruding portion 2A may be formed only on the hook 2 that is rotated.
[0058]
Further, in this embodiment, the case where it is attached to the master rope support 16 and used as the master rope holder is shown, but the use is not limited to this, and it can be applied to various other uses. The design of the structure of the mounting portion 1 can be changed as appropriate according to the application.
[0059]
【The invention's effect】
Since the present invention is configured as described above, the support ring portion can be opened and the ropes and hooks can be connected and disconnected simply by rotating the hook against the biasing mechanism. The attachment and detachment work can be done very easily, and if the hand is released, the urging mechanism automatically returns to the state in which the support ring is formed, so that the connected rope and hook can be removed. This is an epoch-making connector that is highly reliable and extremely practical.
[0060]
In addition, since the present invention is configured as a hook having a protruding portion that protrudes laterally by forming the hook into a substantially L shape or a substantially U shape, the hook having the protruding portion is made a simple configuration. It becomes a connector having a structure that is more practical and can be realized easily.
[0061]
Further, in the invention according to claim 3, since the side portions of the projecting portions are close to or abut with each other and the bearing ring portion has a certain annular shape, the rope or hook connected and held to the bearing ring portion Thus, it is possible to reliably prevent the disconnection and the like, and it is a highly practical connector.
[0062]
Further, in the invention described in claim 4, if only one of the hooks is rotated, both hooks (projections) rotate to widely open the support ring and release the hand. Since both hooks return and rotate so as to automatically form a bearing ring portion, the operability is further improved and the connector is excellent in practicality.
[0063]
Further, in the invention described in claim 5, the support ring portion that can hold the rope, the hook and the like in a surely retaining state is formed, so that it becomes a more practical connector.
[0064]
Further, in the invention according to claim 6, since the support ring portion is formed by abutting so that the protrusions having substantially the same shape overlap each other, the hook and the protrusion constituting the support ring portion are Since the portions are also double-polymerized, extremely strong connection strength is exhibited at the time of hook connection and the like, and the connection tool is more reliable and excellent in safety.
