Description

【０００１】
【発明の属する技術分野】
本願発明は、船舶に使用される錨の改良に関するものである。
【０００２】
【従来の技術】
【特許文献１】
特開２０００−１５３７９６号公報
【０００３】
例えば、レジャーボートや漁船等の小型船舶用の錨として、図１５（Ａ）（Ｂ）に示すようなものが従来から広く知られている。この従来の錨は、固定爪部ａ１を有する錨本体ａと、長尺棒状の接続部材ｂとを備え、接続部材ｂの先端側には、ロープＲに接続するロープ接続部ｂ１を備え、接続部材ｂの後端側を錨本体ａの後端側に回動自在に接続し、錨本体ａには、接続部材ｂを当接させる当接部ａ２を備えたものとし、そして、使用に際しては、図１６に示すように錨のロープ接続部ｂ１に、船舶から伸ばしたロープＲを接続して海中に沈めた後、船舶を移動させてロープＲを引っ張ることにより、接続部材ｂが錨本体ａに対して回動して、接続部材ｂと錨本体ａの固定爪部ａ１とのなす角度Ａが略４５°となる位置で当接部ａ２に当接し、この状態で、それ以上接続部材ｂが錨本体ａに対して回動できないため、海底の岩等の被固定部材Ｈに引っ掛けることができると共に、岩等の被固定部材Ｈに食い込ませるようにして固く固定できる。
【０００４】
しかしながら、このものにおいては、固定爪部ａ１が接続部材ｂに対して略４５°をなした状態に維持されるため、海底の岩等の被固定部材Ｈに固定した錨を外そうとして、図１６に示すようにロープＲを錨の上方側から引っ張り操作して錨に引っ張り力をかけても、岩等の被固定部材Ｈに引っ掛かった錨の固定爪部ａ１には、その引っ張り力の殆どが岩等の被固定部材Ｈを押し上げる上方向きの力として働き、岩等の被固定部材Ｈに食い込んで固く固定した固定爪部ａ１を外し難い場合が多い。そのため、現状では、このように固定爪部ａ１が岩等の被固定部材Ｈから外れなくなると、ロープＲから切断している場合が多く、その結果、ロープＲの切断という作業が強いられると共に、錨を再度購入して取付けなければならないという課題を有する。
【０００５】
上記課題に対して、本願発明の発明者は、特許文献１に記載の発明をした。この発明に係る改良された錨は、接続部材ｂを、錨本体ａに回動自在に接続したものであり、錨本体ａに対する接続部材ｂの回動範囲を規制する規制手段と、その規制を解除する規制解除手段とが備えられたものである。
この規制手段によって、錨本体ａに対する接続部材ｂの回動を、錨本体ａの固定爪部ａ１と接続部材ｂとのなす角度が鋭角をなす範囲に規制しておくことにより、固定爪部ａ１を被固定部材Ｈに食い込ませるようにして固く固定できる。一方、海底に固定した錨を取り外す場合は、規制解除手段によって、接続部材ｂを、錨本体ａの固定爪部ａ１と接続部材ｂとのなす角度を鋭角から鈍角にすることができ、接続部材ｂを引っ張れば、その引っ張り力を、鋭角の状態で引っ張る場合に比して錨本体ａの固定爪部ａ１の長手方向に大きくかけることができ、固定爪部ａ１を被固定部材Ｈから容易に抜くことができる。
【０００６】
しかし、上記の改良された錨であっても、錨本体ａに対して、接続部材ｂが回動中心から円周を描く方向にしか回動できないものであるため、図１７に示すように、海底が傾斜していて、接続部材ｂが鉛直方向を向かない場合等、接続部材ｂに対して真っ直ぐに力がかけられない場合においては、規制解除手段が機能せず、錨本体ａの固定爪部ａ１と接続部材ｂとのなす角度を鋭角から鈍角にすることができない場合があり、固定爪部ａ１が被固定部材Ｈから外れなくなることがあった。
【０００７】
【発明が解決しようとする課題】
本願発明は、以上の実情に鑑み提案されたもので、海底の岩等に容易に確実に引っ掛けて固定できると共に、海底が傾斜している場合等であっても、固定した錨を簡単に外すことのできる錨の提供を目的とする。
【０００８】
【課題を解決するための手段】
本願発明は、錨本体１と、この錨本体１と船舶から伸ばされたロープＲとを接続するものであり、長尺状のものから構成される接続部材２とを備え、錨本体１には、錨本体１の後端側から前端側に向けて突設された固定爪部３が備えられることにより、錨本体１が海底の岩等の被固定部材Ｈに固定可能とされ、接続部材２の前端側がロープＲと接続され、第１の回動として、接続部材２の後端側が、錨本体１の後端側に回動自在に接続され、更に、錨本体１に対する接続部材２の上記の第１の回動の範囲を規制する規制手段２２、４２と、その規制を解除する規制解除手段２３、２４とが備えられたものであり、規制手段２２、４２が、接続部材２に摺動自在に設けられた摺動部材２２と、錨本体１に設けられた当接部４２とを備えたものであり、摺動部材２２が、接続部材２の上記の回動に伴って錨本体１の当接部４２に当接して係止することにより、錨本体１に対する接続部材２の回動範囲が規制され、規制解除手段２３、２４が、錨本体１の当接部４２に当接した摺動部材２２を摺動操作することにより、摺動部材２２が摺動して錨本体１の当接部４２と摺動部材２２との当接による係止が外れるようになされたものであり、第２の回動として、接続部材２の後端側が、錨本体１の固定爪部３に対して、接続部材２の前後方向に伸びる軸線を中心として回動可能であることを特徴とする錨を提供することにより上記課題を解決する。
【０００９】
本願の請求項２に係る発明は、接続部材２が、長尺状の接続本体片２１を備え、接続本体片２１の前端側には、回動自在に取り付けられた操作部材２３が備えられ、接続本体片２１の後端側が、錨本体１に回動自在に取り付けられると共に、接続本体片２１の長手方向に沿って摺動する摺動部材２２を備え、そして、接続本体片２１の後端側には、上記の摺動部材２２を収納する空間である摺動部材用収納部２１ａが備えられたものであり、この摺動部材用収納部２１ａは、他端側に近い方が断面積が小さくなるように形成されたものであり、操作部材２３と摺動部材２２とが、連結部材２４を介して連結されることにより、操作部材２３が接続本体片２１を回動するに伴って、摺動部材２２が接続本体片２１の長手方向に沿って摺動操作され、接続部材２４は、摺動部材２２に対して回動不能に一体化されたものであり、この操作部材２３の前端側に、ロープＲが接続され、このロープＲの引っ張り操作に際して操作部材２３が接続本体片２１を回動することにより、錨本体１の当接部４２と摺動部材２２との当接による係止が外れるようになされたものであることを特徴とする請求項１記載の錨を提供する。
【００１０】
なおここで、上記の「長手方向に沿って摺動操作」とは、摺動部材２２が接続本体片２１の長手方向に対して完全に平行に摺動操作されるものに限られず、多少の角度を持った状態で摺動操作されることも含むものとする。
【００１１】
以上のように構成された本願発明においては、規制手段２２、４２によって、錨本体１に対する接続部材２の回動を、規制手段２２、４２によって、錨本体１の固定爪部３と接続部材２とのなす角度Ａが鋭角をなす範囲に規制しておくことにより、固定爪部３を海底の岩等に被固定部材Ｈに食い込ませるようにして固く固定できる。
【００１２】
一方、海底に固定した錨を取り外す場合は、規制解除手段２３、２４によって、接続部材２を、錨本体１の固定爪部３と接続部材２とのなす角度Ａを鋭角から鈍角にすることにより、接続部材２を引っ張れば、その引っ張り力を、鋭角の状態で引っ張る場合に比して錨本体１の固定爪部３の長手方向に大きくかけることができ、固定爪部３を被固定部材Ｈから容易に抜くことができる。
【００１３】
また、操作部材２３の前端側に接続させたロープＲの引っ張り操作に際し、操作部材２３が接続本体片２１を回動することにより、錨本体１の当接部４２に当接した摺動部材２２が摺動して当接部４２から外れるものとするため、海底に固定した錨を取り外す場合は、船上からロープＲを引っ張って操作部材２３を接続本体片２１に対して回動させれば良く、これにより、当接部４２と摺動部材２２との当接による係止を外すことができ、接続部材２を、錨本体１の固定爪３に対してなす角度Ａを鋭角から鈍角にすることができる。
【００１４】
そして、錨本体１の固定爪部３に対して、接続部材２が、長手方向の軸線を中心として回動可能であることから、傾いた海底等に錨が置かれ、固定爪部３が水平になっていない場合等であっても、接続本体片２１を鉛直方向にして、真っ直ぐに力をかけることができ、被固定部材Ｈから容易に錨を外すことができる。
【００１５】
【発明の実施の形態】
以下、図を基に本願発明の一実施形態を具体的に説明する。
図１は、本願発明の第１実施形態の錨の側面図、図２は、その平面図、図３は、図２のI−I線断面図である。図４は、本願発明の第２実施形態の錨の側面図、図５は、その平面図、図６は、図５のII−II線断面図である。
なお、本説明における方向の表現は、図２に示すように錨を配位した場合において、図示における左・右はそのまま「左・右」とし、図示における上方は「前方」、下方は「後方」と称するものとする。また、「上・下」については各図示の上下方向によって特定する。
【００１６】
まず、本願発明の第１実施形態について説明する。この錨は、錨本体１と、接続部材２とを備えている。
錨本体１は、錨本体１を海底に固定させるための固定爪部３と、固定爪部３を支持した支持部４とを備えている。この第１実施形態においては、固定爪部３は、左右対称である一体のものとして形成されており、先鋭状に形成された爪部３１、３１が備えられている。又、各固定爪部３は、図１に示すように、側面視が略三角形状となっており、この錨本体１を海底に沈めた際、図７（Ａ）に示すように、常時固定爪部３の先端側における爪部３１、３１が後端側（図７（Ａ）における左方側）よりも下方側になる傾斜状態にさせておくためのものである。
【００１７】
支持部４は、図３に示すように、固定爪部３に前後方向に貫通するように形成された取付孔３２に対して回動可能に挿入され、取り付けられている。
そして、このように構成された固定爪部３は、支持部４に左右対称になるように取り付けられることにより、固定爪部３の爪部３１、３１が錨本体１の先端側となるように突設されている。
【００１８】
支持部４は、図３に示すように、接続部材２を取り付ける接続部材取付部４０を備えている。そして、上記のように、支持部４は、固定爪部３に前後方向に貫通するように形成された取付孔３２に対して回動可能に取り付けられている。従って、接続部材２は、錨本体１の固定爪部３に対して、接続部材２の前後方向に伸びる軸線を回動の中心として回動可能に取り付けられた関係になる。これが、請求項にいう第２の回動であり、次に述べる挿入軸４６を中心として回動するものである。
他方、第１の回動として、この接続部材取付部４０は、接続部材２を軸支するための軸４１と、接続部材２を当接させる当接部４２、４２と、接続部材２を案内する案内部４４とを備えている。当接部４２、４２は、後述する接続部材２の摺動部材２２を当接させて係止させるためのもので、この第１実施形態では、接続部材取付部４０の先端の一部をカットして凹部４３を形成することにより、凹部４３の円周方向における両端面を当接部４２、４２としている。案内部４４は、接続部材取付部４０における当接部４２、４２よりも外側の外周面がなしており、軸４１の軸芯を中心にした円弧面に形成されている。
【００１９】
そして、支持部４の後方側には、固定爪部３の取付孔３２に取り付けるためのものである挿入軸４６が突出するように形成されている。また、棒状の抜け止め４７が挿入軸４６を貫通するように取り付けられており、支持部４は、固定爪部３に対して抜けることなく、かつ、回動可能に取り付けられる（第２の回動）。
以上のように、第１の回動は軸４１を中心とする回動であり、第２の回動は挿入軸４６を中心とする回動である。
ここで、抜け止め４７は、固定爪部３に当接することにより、固定爪部３に対する支持部４の回動角度規制手段として機能するものであって、これにより、支持部４に対して固定爪部３を３６０°回動自在とした場合に起こる恐れがある、海中落下時の不安定な挙動を防止できる。
なお本願発明においては、回動角度規制手段による、固定爪部３に対する支持部４の回動角度の範囲を、４０°〜１００°の範囲内で、所望の角度に設定する。
なお、抜け止め４７については、この第１実施形態のような、挿入軸４６に貫通する棒状体に限られるものではなく、種々の形態で実施し得る。また、抜け止め４７において、回動角度規制手段として作用する部分についても、支持部４に設けるものに限らず、固定爪部３や接続部材２に設けても良い。
【００２０】
又、錨本体１の後端側には、図１、図２に示すように横向き防止部材４５が備えられている。この横向き防止部材４５は、錨本体１を海底に沈めた際に固定爪部３が上下になって錨本体１が横向きになるのを防止するためのもので、径小な長尺棒状体から構成されている。この横向き防止部材４５は、固定爪部３の後端部を貫いて固定爪部３の左右側の各々に、固定爪部３よりも側方に突出し、左右対称形状をなして固定されている。
【００２１】
接続部材２は、図２、図３に示すように、接続本体片２１、２１と、接続本体片２１、２１を摺動する摺動部材２２と、摺動部材２２を摺動操作する摺動部材操作手段２３，２４とを備えている。
接続本体片２１、２１は、この第１実施形態では、左右に間隔を隔てて対向するように並設された二つの長尺状の板状体から構成されている。又、接続本体片２１、２１の後方側には、摺動部材用収納部２１ａが備えられている。この摺動部材用収納部２１ａは、摺動部材２２を摺動自在に収納するための空間であり、この実施形態では、二つの接続本体片２１、２１各々に板状の架設部材２１ｂ、２１ｂを架け渡すことにより、二つの接続本体片２１、２１の間に、断面四角形状の摺動部材用収納部２１ａを区画形成している。なお、接続本体片２１、２１と架設部材２１ｂ、２１ｂとを当初から一体に形成したものとしても良い。
そして、これらの接続本体片２１、２１の後端側が、錨本体１における支持部４の接続部材取付部４０の軸４１に回動自在に取り付けられることにより、接続本体片２１、２１の先端側が、軸４１を回動軸にして、接続本体片２１、２１と錨本体１とが左右方向に重なり合い両者の軸方向が揃って両者のなす角度が０°となる図１に示す位置から、接続本体片２１、２１と錨本体１とのなす角度Ａ（第２実施形態に係る図７〜図１１に示す）が鈍角になるまでの範囲を上下両方向に回動する。
【００２２】
摺動部材２２は、上述の錨本体１の当接部４２、４２により、錨本体１に対する接続部材２の回動範囲を規制する規制手段をなすもので、接続本体片２１、２１の摺動部材用収納部２１ａ内に収納可能な幅及び高さを有する直方体状のものから構成されている。この第１実施形態においては、摺動部材２２の前端部と連結部材２４の後端部とが回動不能に一体化されている。そして、摺動部材２２は、摺動部材用収納部２１ａ内に収納されることにより、接続本体片２１、２１の長手方向に沿って摺動できるように配位されている。
なお、この第１実施形態においては、上記のように、摺動部材２２と連結部材２４とが一体化されたものであるため、図６（第２実施例の場合）に示すように、操作部材２３を接続本体片２１、２１に対して回動させた際、連結部材２４が接続本体片２１、２１に対して傾くため、連結部材２４と一体化した摺動部材２２もまた、接続本体片２１、２１に対して傾く（図示はしない）。よって、摺動部材用収納部２１ａは、図３に示すように、前端側が広く、後端側が狭く形成されている。つまり、各架設部材２１ｂ、２１ｂの対向する面間距離が、各架設部材２１ｂ、２１ｂにおける前端側２１ｃが広く、後端側２１ｄが狭く形成されている。そのため、後端側２１ｄよりも前端側２１ｃの方が、各架設部材２１ｂ、２１ｂと摺動部材２２と間の隙間が広くなっており、各架設部材２１ｂ、２１ｂに対する摺動部材２２の動作の自由度が高い。よって、摺動部材２２が接続本体片２１、２１に対して傾いた場合であっても、摺動部材２２が支障なく摺動可能となっている。
【００２３】
摺動部材操作手段は、棒状の操作部材２３と、棒状の連結部材２４とを備えている。
操作部材２３は、図１〜図３に示すように、その先端側に、ロープＲ（図７（Ａ）（Ｂ）に図示）を接続するロープ接続部２３ａが、後端側には、連結部材２４を回動自在に連結する連結部２３ｂが、夫々備えられている。そして、この操作部材２３のロープ接続部２３ａと連結部２３ｂとの間の部分が、接続本体片２１、２１の先端に回動自在に取り付けられている。
連結部材２４は、先端側が操作部材２３の連結部２３ｂに回動自在に連結され、連結部材２４の後端側が摺動部材２２に回動不能に一体化するように連結され、接続本体片２１、２１の間に移動可能に配位されている。
【００２４】
このようにして連結部材２４を介して操作部材２３に接続された摺動部材２２は、操作部材２３の長手方向と接続本体片２１、２１の長手方向とが同方向を向いて一致した状態で、図３に示すように摺動部材２２の後部側が錨本体１の支持部４における接続部材取付部４０の凹部４３に入り込んだ状態になる。又、摺動部材２２が支持部４の凹部４３に入り込んだ状態から、操作部材２３が接続本体片２１、２１を回動するに伴って支持部４と退行する方向に摺動して接続部材取付部４０の凹部４３内から抜け出る。
従って、摺動部材２２は、操作部材２３の回動の動きに伴って、接続部材取付部４０の軸４１からの距離が接続部材取付部４０の案内部４４の半径より短くなる位置から長くなる位置までの範囲を自在に摺動して凹部４３内を出入りし、摺動部材２２が錨本体１の凹部４３に入り込んだ状態で接続本体片２１、２１が支持部４に対して回動していくと摺動部材２２が接続部材取付部４０の当接部４２、４２に当接して係止する。本実施形態では、摺動部材２２と接続部材取付部４０の当接部４２、４２とが当接した状態で、図８に示すように接続本体片２１、２１と固定爪部３とのなす角度Ａが略４５°になるように設定している。一方、摺動部材２２が錨本体１の凹部４３から抜け出た状態で、接続本体片２１、２１が支持部４に対して回動しても摺動部材２２と接続部材取付部４０の当接部４２、４２とは当接しない。
【００２５】
次に、本願発明の第２実施形態について説明する。なお、上記第１実施形態と同様の部分については説明を省略する。
この第２実施形態においては、固定爪部３は、図５に示すように、左右一対をなす二つから構成されており、各々は、長尺板状のものから構成され、各々には、先鋭状に形成された爪部３１、３１が備えられている。又、各固定爪部３は、爪傾斜用部材１３、１３を夫々備えている。これらの爪傾斜用部材１３、１３は、この錨本体１を海底に沈めた際、図７（Ａ）に示すように常時固定爪部３の先端側の爪部３１、３１が後端側（図７（Ａ）における左方側）より下方側になる傾斜状態にさせておくためのもので、各々は、略三角形状を呈する板状のものから構成されている。そして、各爪傾斜用部材１３、１３は、固定爪３を基準に上下対称になるように固定爪３に取り付けられることにより、固定爪３各々の後端から略爪部３１、３１まで伸ばされていると共に、固定爪３からの上下高さが固定爪３の爪部３１側に行くに従って漸次低くなるようになされている。
【００２６】
又、第１実施形態と同様、錨本体１の後端側には、図４、図５に示すように横向き防止部材４５が備えられている。この横向き防止部材４５は、各爪傾斜用部材１３、１３の後端部を貫いて各爪傾斜用部材１３、１３の左右側の各々に、固定爪部３よりも側方に突出し、各爪傾斜用部材１３、１３に左右対称形状をなして固定されている。
【００２７】
接続部材２の後方側に備えられる摺動部材用収納部２１ａは、この第２実施形態では、二つの接続本体片２１、２１各々の上端側及び下端側に板状の架設部材２１ｂ、２１ｂを、各架設部材２１ｂ、２１ｂの対向する面間が平行となるように架け渡すことにより、二つの接続本体片２１、２１の間に、断面直方体形状の摺動部材用収納部２１ａを区画形成している。
【００２８】
摺動部材操作手段における連結部材２４は、先端側が操作部材２３の連結部２３ｂに回動自在に連結され、連結部材２４の後端側が摺動部材２２の連結部２２ａに回動自在に連結され、接続本体片２１、２１の間に移動可能に配位されている。
【００２９】
この第２実施形態における摺動部材２２は、操作部材２３の長手方向と接続本体片２１、２１の長手方向とが同方向を向いて一致した状態で、図６に示すように摺動部材２２の後部側が錨本体１の支持部４における接続部材取付部４０の凹部４３に入り込んだ状態になる。又、摺動部材２２が支持部４の凹部４３に入り込んだ状態から、操作部材２３が接続本体片２１、２１を回動するに伴って支持部４と退行する方向に摺動して接続部材取付部４０の凹部４３内から抜け出る。従って、摺動部材２２は、操作部材２３の回動の動きに伴って、接続部材取付部４０の軸４１からの距離が接続部材取付部４０の案内部４４の半径より短くなる位置から長くなる位置までの範囲を自在に摺動して凹部４３内を出入りし、摺動部材２２が錨本体１の凹部４３に入り込んだ状態で接続本体片２１、２１が支持部４に対して回動していくと摺動部材２２が接続部材取付部４０の当接部４２、４２に当接して係止する。
【００３０】
次に、以上のように構成された本願発明の錨の使用方法について、第２実施形態に係る錨を取り上げて説明する。
図７（Ａ）に示すように操作部材２３のロープ接続部２３ａに、船舶から伸ばしたロープＲの後端を接続した後、錨を海底に沈める。錨が海底に沈む際、錨本体１の固定爪３が下方になった場合でも、横向き防止部材４５の先端が海底に当たって錨本体１の固定爪３が側方側になって海底に沈む。又、錨本体１の上面側又は下面側の何れが下方側になって海底に沈むかは判らないが、錨本体１が上下対称になっているため、錨本体１の上面側又は下面側の何れが下方側になっても同じ形で海底に沈ませることができる。
【００３１】
その後、図７（Ｂ）に示すように船舶を動かす等してロープＲを引っ張り、海底を引きずるように錨を移動させる。これにより、錨の固定爪部３を海底の岩や砂等の被固定部材Ｈに引っ掛けることができる。固定爪部３を海底の被固定部材Ｈに引っ掛けた後は、ロープＲを引っ張ると、固定爪部３に引っ掛けた被固定部材Ｈによって抵抗がかかるため、接続本体片２１、２１が錨本体１に対して回動し、接続本体片２１、２１と固定爪部３とのなす角度Ａが徐々に大きくなっていくが、その際、操作部材２３がロープＲによって斜め前方側に引っ張られるため、接続本体片２１、２１の長手方向が操作部材２３の長手方向に一致した状態になって引っ張られ、図８に示すように、摺動部材２２の後部側が錨本体１の支持部４における接続部材取付部４０の凹部４３に入り込んだ状態を維持する。従って、接続本体片２１、２１が錨本体１に対して回動していくと摺動部材２２が錨本体１の当接部４２に当接し、接続本体片２１、２１が錨本体１に対してそれ以上回動できず、接続本体片２１、２１と固定爪部３とのなす角度Ａが略４５°をなした状態で引っ張ることができ、固定爪部３を海底の被固定部材Ｈに食い込ませるようにして容易に、しかも固く固定できる。
【００３２】
一方、固定爪部３を海底の被固定部材Ｈに食い込ませて固定した錨を外す場合は、船上からロープＲを手繰り寄せるようにして図９に示すようにロープＲを錨の上方側から引っ張り操作する。この上方側への引っ張りにより、接続本体片２１、２１は固定爪部３に対してなす角度Ａをそれ以上大きくできずに回動しないため、操作部材２３が接続本体片２１、２１に対して回動する。
【００３３】
この操作部材２３の接続本体片２１、２１に対する回動により、連結部材２４を介して、摺動部材２２が摺動部材用収納部２１ａを支持部４と退行する方向に摺動して、接続部材取付部４０の凹部４３内から抜け出て、摺動部材２２と当接部４２との当接による係止が外れる。これにより、接続本体片２１、２１と固定爪部３とのなす角度Ａが略４５°以上に大きくならないように規制されていた接続本体片２１、２１の回動範囲の規制が解除され、接続本体片２１、２１が錨本体１に対して回動し始め、図１０、図１１に示すように接続本体片２１、２１と固定爪部３とのなす角度Ａが９０°以上の鈍角になるまで回動する。この回動により、固定爪部３にかかるロープＲからの引っ張り力は、固定爪部３の長手方向に沿う方向に大きく作用し、固定爪部３を被固定部材Ｈから容易に抜くことができ、錨を外すことができる。
【００３４】
なお、摺動部材２２が凹部４３から出て接続本体片２１、２１が錨本体１に対して回動可能状態になると、操作部材２３と接続本体片２１、２１とが一直線状になろうとするが、摺動部材２２が案内部４４に当接して支持部４側に摺動できないため、操作部材２３と接続本体片２１、２１とが折れ曲がった状態を維持しながら共に後方側に回動し、接続本体片２１、２１が固定爪部３に対して角度Ａを大きくして行く。
【００３５】
そして、第２の回動として前述のように、支持部４（より詳しくは、支持部４及びこの支持部４に対して接続部材取付部４０を介して取り付けられた接続部材２）は、固定爪部３に対して、前後方向に伸びる軸線を中心として回動可能であるため、図１７に示すように、傾いた海底等に錨が置かれ、固定爪部３が水平になっていない場合等であっても、図８の矢印Ｔに示すように、支持部４を回動させることができ、支持部４に連結された接続本体片２１，２１を、図１７に示すように鉛直方向にして、真っ直ぐに力をかけることができ、被固定部材Ｈから容易に錨を外すことができる。
ここで、上記のように、支持部４は固定爪部３に対して、前後方向に伸びる軸線を中心として回動可能であるため、図１７に示すように、傾いた海底等に錨が置かれ、固定爪部３が水平になっていない場合等であっても、図８に示すように、支持部４を回動Ｔさせることができ、支持部４に連結された接続本体片２１，２１を、図１７に示すように鉛直方向にして、真っ直ぐに力をかけることができ、被固定部材Ｈから容易に錨を外すことができる。
【００３６】
なお、本願発明の第１実施形態においては、上記のように摺動部材２２と連結部材２４とが一体化されているが、摺動部材用収納部２１ａが、図３に示すように、前端側が広く、後端側が狭く形成されているため、摺動部材用収納部２１ａに対して摺動部材２２が支障なく摺動でき、この第２実施形態と全く同様の作用をなすことができる。
これにより、第２実施形態に比べて第１実施形態の方が、摺動部材２２の連結部２２ａや、連結のためのピン等を省略できるため、錨の製造コストを削減することができ、有利である。
【００３７】
又、錨を外した後、再度錨を使用する場合は、接続本体片２１、２１と固定爪部３とのなす角度Ａが鈍角になった図１０に示す状態のまま、海底に沈めて、上述したと同様に船舶を動かす等してロープＲを引っ張り操作する。その際、そのロープＲの引っ張り力によって操作部材２３が接続本体片２１、２１に一直線状になろうとして摺動部材２２が錨本体１の支持部４側に摺動しようとするが、摺動部材２２が軸４１と同芯の円弧に形成された支持部４の案内部４４に当接しているため、摺動部材２２は、接続本体片２１、２１に対して摺動することなくその位置を維持しながら案内部４４に沿って案内される。従って、接続本体片２１、２１は、固定爪部３とのなす角度Ａが鈍角になった状態でも、錨本体１に対して爪部３１、３１側へ回動し得る状態を維持し、ロープＲの引っ張りによって接続本体片２１、２１が錨本体１に対して爪部３１、３１側へ回動して固定爪部３に対して角度Ａを小さくして行く。そして、摺動部材２２が凹部４３に合致すると、操作部材２３が接続本体片２１、２１とが一直線状になろうとし摺動部材２２が錨本体１の支持部４側に摺動して凹部４３内に入り込み、上述した図８に示す状態にできる。
【００３８】
又、錨を海底に沈めてロープＲを引っ張り操作する際、図１２に示すように固定爪部３の爪部３１、３１が後方側になった状態で操作部材２３を固定爪部３の爪部３１、３１と反対方向に引っ張る場合もあるが、仮にこのような状態になっても、接続本体片２１、２１と錨本体１とが互いに回動するため、操作部材２３の引っ張りに伴って錨本体１が固定爪部３の爪部３１、３１と反対側の後端側を軸にして海底を回転し、図１２中に破線で示すように固定爪部３の爪部３１、３１が前方側にくる。固定爪部３が前方側にくると摺動部材２２が凹部４３に合致して凹部４３内に入り込み、図４に示す状態にできる。
【００３９】
なお、支持部４の当接部４２、４２は、上記第１・第２実施形態の形態のものに限らず、例えば図１３に示すように棒状体５、５を、左右の爪傾斜用部材１３に架け渡して棒状体５、５の側面を当接部４２、４２としても良い。なお、この場合は、案内部４４は、有しないものになる。
【００４０】
又、支持部４の案内部４４は、軸４１と同芯の円弧状に形成したものに限らず、例えば図１４に示すように後方側に漸次軸４１から距離が短くなる直線状に形成したものでも良い。更には、案内部４４を設ける形態のものに限らず、図１３に示すように設けない形態のものであっても良い。ただし、案内部４４を、直線状に形成した場合や設けない場合、例えば図１４中に点線で示すように、摺動部材２２が接続部材取付部４０の凹部４３内から抜け出た後、支持部４に対する接続本体片２１、２１の後方側への回動に際して摺動部材２２が支持部４側に摺動する。この状態になると、接続本体片２１、２１が支持部４に対して前方側へ回動し難くなってしまい、その結果、再度錨を使用する場合は、操作部材２３を手で接続本体片２１、２１に対して回動操作して摺動部材２２を支持部４と反対側に摺動させた後、接続本体片２１、２１を支持部４に対して前方側に回動して摺動部材２２を凹部４３内に入り込ませておかなければならない。従って、上記第１・第２実施形態のように案内部４４を、軸４１と同芯の円弧状に形成したものにしておけば、そのような操作をすることなく再度錨を使用できる点で有利である。
【００４１】
また、案内部４４の位置は、接続本体片２１、２１と固定爪部３とのなす角度Ａが略４５°になる位置に限らず、両者のなす角度Ａが鋭角をなす範囲であれば良く、適宜変更し得る。
【００４２】
又、本願発明の錨の使用される船舶の種類は、特に限定されず、レジャーボート、小型船舶、或いは漁船等の種々のものに使用し得る。
【００４３】
【発明の効果】
以上、本願発明は、規制手段２２、４２によって、固定爪３を海底の岩等に被固定部材Ｈに食い込ませるようにして固く固定できる。一方、海底に固定した錨を取り外す場合は、規制解除手段２３、２４によって、接続部材２を引っ張り操作すれば、固定爪３を被固定部材Ｈから簡単に抜くことができ、海底に固定した錨を容易に取り外すことができる。
【００４４】
また、固定爪部３を海底の被固定部材Ｈに食い込ませて固定した錨を外す場合は、船上からロープＲを引っ張って操作部材２３を接続本体片２１に対して回動させれば良く、これにより、当接部４２と摺動部材２２との当接による係止を外すことができ、接続部材２を、錨本体１の固定爪３に対してなす角度Ａを鋭角から鈍角にすることができる。従って、海底に固定した錨を容易に取り外すことができる。
【００４５】
そして、錨本体１の固定爪部３に対して、接続部材２が、長手方向の軸線を中心として回動可能であることから、傾いた海底等に錨が置かれ、固定爪部３が水平になっていない場合等であっても、接続本体片２１を鉛直方向にして、真っ直ぐに力をかけることができ、被固定部材Ｈから容易に錨を外すことができる。

[Patent Document 1]
        Japanese Patent Laid-Open No. 2000-153796
[0003]
  For example, as shown in FIGS. 15 (A) and 15 (B), a boat for small boats such as leisure boats and fishing boats has been widely known. This conventional scissors includes a scissors main body a having a fixed claw portion a1 and a long rod-shaped connecting member b, and is provided with a rope connecting portion b1 connected to the rope R on the distal end side of the connecting member b. The rear end side of the member b is pivotally connected to the rear end side of the heel body a, and the heel body a is provided with an abutting portion a2 for abutting the connecting member b. 16, after connecting the rope R extended from the ship to the rope connection part b1 of the anchor and sinking it in the sea, the ship is moved and the rope R is pulled, so that the connecting member b is attached to the anchor body a To the contact portion a2 at a position where the angle A formed by the connection member b and the fixed claw portion a1 of the bag main body a is approximately 45 °, and in this state, the connection member b is further increased. Can not be rotated with respect to the main body a, so it can be hooked to a fixed member H such as a rock on the seabed. Together, it can be fixed firmly so as to bite into the fixing object H rock like.
[0004]
  However, in this case, since the fixed claw portion a1 is maintained at an angle of approximately 45 ° with respect to the connection member b, the anchor fixed to the fixed member H such as a rock on the seabed is to be removed. As shown in FIG. 16, even if the rope R is pulled from the upper side of the reed and a tensile force is applied to the reed, the fixed claw part a1 of the reed hooked on the fixed member H such as a rock has almost all the pulling force. Often acts as an upward force that pushes up the fixed member H such as a rock, and it is often difficult to remove the fixed claw portion a1 that bites into the fixed member H such as a rock and is firmly fixed. Therefore, at present, when the fixed claw a1 does not come off from the fixed member H such as a rock as described above, in many cases, it is cut from the rope R. As a result, the work of cutting the rope R is forced, The problem is that the bag must be purchased and installed again.
[0005]
  The inventor of the present invention has made the invention described in Patent Document 1 with respect to the above problems. The improved scissors according to the present invention are such that the connecting member b is pivotally connected to the scissors main body a, the restricting means for restricting the rotation range of the connecting member b with respect to the scissors main body a, and the regulation thereof. And a restriction releasing means for releasing.
  By restricting the rotation of the connecting member b with respect to the heel body a by this restricting means within a range in which the angle formed between the fixed claw portion a1 of the heel body a and the connecting member b forms an acute angle, the fixed claw portion a1. Can be firmly fixed by biting into the fixed member H. On the other hand, when removing the anchor fixed to the seabed, the restriction releasing means can change the angle between the connecting claw part a1 of the anchor main body a and the connecting member b from an acute angle to an obtuse angle by the connecting member b. If b is pulled, the pulling force can be greatly applied in the longitudinal direction of the fixed claw portion a1 of the heel body a as compared with the case of pulling at an acute angle, and the fixed claw portion a1 can be easily removed from the fixed member H. Can be removed.
[0006]
  However, even with the above-described improved scissors, since the connecting member b can only rotate in the direction of drawing the circumference from the center of rotation with respect to the scissors body a, as shown in FIG. When the seabed is inclined and the connecting member b does not face the vertical direction, for example, when the force is not applied straight to the connecting member b, the restriction releasing means does not function, and the fixing claw of the main body a In some cases, the angle formed by the part a1 and the connection member b cannot be changed from an acute angle to an obtuse angle, and the fixed claw part a1 may not be detached from the fixed member H.
[0007]
[Problems to be solved by the invention]
  The present invention has been proposed in view of the above circumstances, and can be easily hooked and fixed on rocks on the seabed, and can be easily removed even when the seabed is inclined. The purpose is to provide a bag that can be used.
[0008]
[Means for Solving the Problems]
  The present invention isThe rod body 1 is connected to the rod body 1 and the rope R extended from the ship, and includes a connecting member 2 made of a long shape. By providing the fixed claw portion 3 projecting from the rear end side toward the front end side, the main body 1 is attached to the sea. It can be fixed to a fixed member H such as a rock at the bottom, the front end side of the connection member 2 is connected to the rope R, and as a first rotation, the rear end side of the connection member 2 is connected to the rear end side of the main body 1. Further, there are provided restricting means 22, 42 for restricting the range of the first rotation of the connecting member 2 with respect to the bag main body 1 and restriction releasing means 23, 24 for releasing the restriction. The restricting means 22, 42 includes a sliding member 22 slidably provided on the connection member 2 and an abutting portion 42 provided on the bag main body 1. As the moving member 22 abuts and engages with the abutting portion 42 of the heel body 1 as the connecting member 2 rotates, the rotation range of the connecting member 2 with respect to the heel body 1 is restricted, and the regulation is restricted. The release means 23 and 24 slide the sliding member 22 that is in contact with the contact portion 42 of the bag body 1. Thus, the sliding member 22 is slid so that the locking caused by the contact between the contact portion 42 of the bag main body 1 and the sliding member 22 is released. The above-mentioned problem is solved by providing a scissors characterized in that the rear end side of the scissors 2 can be rotated around an axis extending in the front-rear direction of the connecting member 2 with respect to the fixed claw portion 3 of the scissors body 1.

The operation member 23 and the sliding member 22 are connected via the connecting member 24 so that the operation member 23 rotates the connection main body piece 21. The sliding member 22 is slid along the longitudinal direction of the connecting body piece 21, and the connecting member 24 is integrated with the sliding member 22 so as not to rotate.Front endFurther, when the rope R is connected, and the operation member 23 rotates the connection main body piece 21 during the pulling operation of the rope R, the contact by the contact portion 42 of the heel body 1 and the sliding member 22 is locked. The bag according to claim 1, wherein the bag is configured to be detached.
[0010]
  Here, the above-mentioned “sliding operation along the longitudinal direction” is not limited to the sliding operation of the sliding member 22 completely parallel to the longitudinal direction of the connection body piece 21, This includes sliding operation with an angle.
[0011]
  In the present invention configured as described above, the restricting means 22 and 42 rotate the connecting member 2 with respect to the heel body 1, and the restricting means 22 and 42 cause the fixing claw portion 3 of the heel body 1 and the connecting member 2 to rotate. By restricting the angle A to an acute angle, the fixed claw portion 3 can be firmly fixed so as to bite the fixed member H into a rock or the like on the seabed.
[0012]
  On the other hand, when removing the anchor fixed to the seabed, the restriction release means 23 and 24 are used to change the connecting member 2 from an acute angle to an obtuse angle by the connecting claws 3 and the connecting member 2 of the anchor body 1. If the connecting member 2 is pulled, the pulling force can be applied more in the longitudinal direction of the fixing claw portion 3 of the heel body 1 than when it is pulled at an acute angle. Can be removed easily.
[0013]
  Further, the operation member 23Front endWhen the rope R connected to the cable is pulled, the operation member 23 rotates the connection main body piece 21 so that the sliding member 22 that is in contact with the contact portion 42 of the heel body 1 slides and comes into contact with the contact portion. In order to remove the anchor fixed to the sea floor, the operation member 23 may be rotated with respect to the connection main body piece 21 by pulling the rope R from the ship. And the sliding member 22 can be unlocked, and the angle A of the connecting member 2 with respect to the fixing claw 3 of the heel body 1 can be changed from an acute angle to an obtuse angle.
[0014]
  And since the connection member 2 can rotate centering on the longitudinal axis with respect to the fixed nail | claw part 3 of the main body 1, the ridge is put on the inclined seabed etc., and the fixed claw part 3 is horizontal. Even if it is not, etc., the connecting body piece 21 can be set in the vertical direction, and a force can be applied straight, and the hook can be easily removed from the fixed member H.
[0015]

The sideways prevention member 45 penetrates the rear end portion of the fixed claw portion 3 and projects laterally from the fixed claw portion 3 to the left and right sides of the fixed claw portion 3, and is fixed in a bilaterally symmetric shape. .
[0021]
  As shown in FIGS. 2 and 3, the connection member 2 includes connection body pieces 21, 21, a sliding member 22 that slides on the connection body pieces 21, 21, and a slide that slides the sliding member 22. Member operation means 23 and 24 are provided.
  In the first embodiment, the connection main body pieces 21 and 21 are composed of two long plate-like bodies arranged side by side so as to face each other with a gap left and right. Further, on the rear side of the connection main body pieces 21, 21, a sliding member storage portion 21 a is provided. The sliding member storage portion 21a is a space for slidably storing the sliding member 22, and in this embodiment, plate-like installation members 21b and 21b are provided on the two connection main body pieces 21 and 21, respectively. , A sliding member storage portion 21a having a square cross section is formed between the two connection main body pieces 21 and 21. The connection main body pieces 21 and 21 and the erection members 21b and 21b may be integrally formed from the beginning.
  And the rear end side of these connection main-body pieces 21 and 21 is rotatably attached to the axis | shaft 41 of the connection member attachment part 40 of the support part 4 in the collar body 1, and the front end side of the connection main-body pieces 21 and 21 is attached. 1 with the shaft 41 as a rotation axis, the connecting body pieces 21 and 21 and the heel body 1 are overlapped in the left-right direction, the axial directions of the two are aligned, and the angle between them is 0 °. The range until the angle A (shown in FIGS. 7 to 11 according to the second embodiment) formed by the main body pieces 21 and 21 and the bag main body 1 becomes an obtuse angle is rotated in both the upper and lower directions.
[0022]
  The sliding member 22 serves as a restricting means for restricting the rotation range of the connecting member 2 with respect to the rod main body 1 by the contact portions 42 and 42 of the rod main body 1 described above. It is comprised from the rectangular parallelepiped shape which has the width | variety and height which can be accommodated in the accommodating part 21a for members. In this 1st Embodiment, the front-end part of the sliding member 22 and the rear-end part of the connection member 24 are integrated so that rotation is impossible. The sliding member 22 is arranged so as to be slidable along the longitudinal direction of the connection main body pieces 21 and 21 by being housed in the sliding member housing portion 21a.
  In the first embodiment, since the sliding member 22 and the connecting member 24 are integrated as described above, the operation is performed as shown in FIG. 6 (in the case of the second embodiment). When the member 23 is rotated with respect to the connection main body pieces 21, 21, the connecting member 24 is inclined with respect to the connection main body pieces 21, 21, so that the sliding member 22 integrated with the connection member 24 is also the connection main body. It inclines with respect to the pieces 21 and 21 (not shown). Accordingly, as shown in FIG. 3, the sliding member storage portion 21a is formed such that the front end side is wide and the rear end side is narrow. That is, the distance between the facing surfaces of the erection members 21b and 21b is such that the front end side 21c and the rear end side 21d of the erection members 21b and 21b are narrower. Therefore, the front end side 21c is wider than the rear end side 21d so that the gaps between the installation members 21b and 21b and the sliding member 22 are wider, and the operation of the sliding member 22 relative to the installation members 21b and 21b is increased. High degree of freedom. Therefore, even when the sliding member 22 is inclined with respect to the connection main body pieces 21, 21, the sliding member 22 can slide without any trouble.
[0023]
  The sliding member operating means includes a bar-shaped operating member 23 and a bar-shaped connecting member 24.
  As shown in FIGS. 1 to 3, the operation member 23 has a rope connection portion 23 a for connecting a rope R (shown in FIGS. 7A and 7B) on the front end side and a connection on the rear end side. A connecting portion 23b that rotatably connects the member 24 is provided. And the part between the rope connection part 23a and the connection part 23b of this operation member 23 is attached to the front-end | tip of the connection main-body pieces 21 and 21 so that rotation is possible.
  The connecting member 24 is connected so that the front end side thereof is turnably connected to the connecting portion 23 b of the operation member 23, and the rear end side of the connecting member 24 is connected to the sliding member 22 so as to be unrotatably integrated. , 21 are movably coordinated.
[0024]
  In this way, the sliding member 22 connected to the operating member 23 via the connecting member 24 is in a state where the longitudinal direction of the operating member 23 and the longitudinal direction of the connecting body pieces 21 and 21 are aligned in the same direction. As shown in FIG. 3, the rear side of the sliding member 22 enters the concave portion 43 of the connection member mounting portion 40 in the support portion 4 of the bag main body 1. Further, from the state in which the sliding member 22 enters the concave portion 43 of the support portion 4, the operating member 23 slides in the direction of retreating with the support portion 4 as the connection main body pieces 21 and 21 are rotated, thereby connecting the connection member. It slips out of the recess 43 of the mounting portion 40.
  Therefore, the sliding member 22 becomes longer from the position where the distance from the shaft 41 of the connecting member mounting portion 40 is shorter than the radius of the guide portion 44 of the connecting member mounting portion 40 as the operation member 23 rotates. The connecting body pieces 21 and 21 rotate with respect to the support portion 4 in a state where the range up to the position freely slides in and out of the recess 43 and the sliding member 22 enters the recess 43 of the bag body 1. Then, the sliding member 22 comes into contact with and engages with the contact parts 42 and 42 of the connection member mounting part 40. In the present embodiment, the connecting body pieces 21 and 21 and the fixed claw portion 3 are formed with the sliding member 22 and the contact portions 42 and 42 of the connection member mounting portion 40 in contact with each other as shown in FIG. The angle A is set to be approximately 45 °. On the other hand, even if the connection main body pieces 21 and 21 rotate with respect to the support portion 4 in a state where the slide member 22 has come out of the recess 43 of the bag main body 1, the contact between the slide member 22 and the connection member mounting portion 40 It does not contact the parts 42 and 42.
[0025]
  Next, a second embodiment of the present invention will be described. The description of the same parts as those in the first embodiment is omitted.
  In the second embodiment, as shown in FIG. 5, the fixed claw portion 3 is composed of a pair of left and right, each composed of a long plate, Claw portions 31 and 31 formed in a sharp shape are provided. Each fixed claw portion 3 is provided with claw-inclining members 13 and 13, respectively. As shown in FIG. 7 (A), the claw-inclining members 13 and 13 are configured so that the claw portions 31 and 31 on the front end side of the fixed claw portion 3 are always on the rear end side (see FIG. 7A). This is for keeping the inclined state lower than the left side in FIG. 7 (A), and each is composed of a plate-like member having a substantially triangular shape. Each of the claw-inclining members 13 and 13 is attached to the fixed claw 3 so as to be vertically symmetric with respect to the fixed claw 3, thereby extending from the rear end of each fixed claw 3 to the substantially claw portions 31 and 31. In addition, the vertical height from the fixed claw 3 is gradually lowered toward the claw portion 31 side of the fixed claw 3.
[0026]
  Similarly to the first embodiment, a laterally preventing member 45 is provided on the rear end side of the bag main body 1 as shown in FIGS. The sideways prevention member 45 protrudes laterally from the fixed claw portion 3 to the left and right sides of the claw tilting members 13, 13 through the rear end portions of the claw tilting members 13, 13. It is fixed to the tilting members 13 and 13 in a symmetrical manner.
[0027]
  In this second embodiment, the sliding member storage portion 21a provided on the rear side of the connection member 2 is provided with plate-like installation members 21b, 21b on the upper end side and the lower end side of each of the two connection main body pieces 21, 21. The sliding member storage portion 21a having a rectangular parallelepiped section is formed between the two connection main body pieces 21 and 21 by spanning the mounting members 21b and 21b so that the opposing surfaces are parallel to each other. ing.
[0028]
  The connecting member 24 in the sliding member operating means is pivotally connected at its distal end side to the connecting portion 23b of the operating member 23, and the rear end side of the connecting member 24 is rotatably connected to the connecting portion 22a of the sliding member 22. The connection main body pieces 21 are arranged so as to be movable.
[0029]
  The sliding member 22 according to the second embodiment has the sliding member 22 as shown in FIG. 6 in a state where the longitudinal direction of the operation member 23 and the longitudinal direction of the connection main body pieces 21 and 21 are aligned in the same direction. The rear portion side enters the recess 43 of the connection member mounting portion 40 in the support portion 4 of the bag main body 1. Further, from the state in which the sliding member 22 enters the concave portion 43 of the support portion 4, the operating member 23 slides in the direction of retreating with the support portion 4 as the connection main body pieces 21 and 21 are rotated, thereby connecting the connection member. It slips out of the recess 43 of the mounting portion 40. Therefore, the sliding member 22 becomes longer from the position where the distance from the shaft 41 of the connecting member mounting portion 40 is shorter than the radius of the guide portion 44 of the connecting member mounting portion 40 as the operation member 23 rotates. The connecting body pieces 21 and 21 rotate with respect to the support portion 4 in a state where the range up to the position freely slides in and out of the recess 43 and the sliding member 22 enters the recess 43 of the bag body 1. Then, the sliding member 22 comes into contact with and engages with the contact parts 42 and 42 of the connection member mounting part 40.
[0030]
  Next, a method of using the bag of the present invention configured as described above will be described by taking up the bag according to the second embodiment.
  As shown in FIG. 7A, after connecting the rear end of the rope R extended from the ship to the rope connecting portion 23a of the operation member 23, the dredging is submerged in the seabed. When the anchor sinks to the seabed, even if the fixed claws 3 of the anchor body 1 are in the downward direction, the tip of the lateral prevention member 45 hits the seabed, and the anchor claws 3 of the anchor body 1 become sideways and sink to the seabed. In addition, it is not known whether the upper surface side or the lower surface side of the dredged main body 1 is the lower side and sinks to the seabed. However, since the dredged main body 1 is vertically symmetrical, Whichever is on the lower side, it can be sunk into the seabed in the same way.
[0031]
  Thereafter, as shown in FIG. 7B, the rope R is pulled by moving the ship or the like, and the anchor is moved so as to drag the seabed. Thereby, the fixed nail | claw part 3 of a ridge can be hooked on to-be-fixed members H, such as a rock and sand of a seabed. After the fixed claw portion 3 is hooked on the fixed member H on the seabed, when the rope R is pulled, resistance is applied by the fixed member H hooked on the fixed claw portion 3, so that the connection main body pieces 21 and 21 are connected to the main body 1. , And the angle A formed by the connecting body pieces 21 and 21 and the fixed claw portion 3 gradually increases. At this time, the operation member 23 is pulled obliquely forward by the rope R. As shown in FIG. 8, the connecting body pieces 21, 21 are pulled in a state where the longitudinal direction of the connecting body pieces 21, 21 coincides with the longitudinal direction of the operation member 23. The state of entering the concave portion 43 of the mounting portion 40 is maintained. Therefore, when the connecting body pieces 21 and 21 rotate with respect to the bag body 1, the sliding member 22 comes into contact with the contact portion 42 of the bag body 1, and the connecting body pieces 21 and 21 move with respect to the bag body 1. And can be pulled in a state where the angle A formed between the connecting main body pieces 21 and 21 and the fixed claw portion 3 is approximately 45 °, and the fixed claw portion 3 is attached to the fixed member H on the seabed. It can be easily and firmly fixed by biting.
[0032]
  On the other hand, when removing the anchor with the fixed claw portion 3 biting into the fixed member H on the seabed, pull the rope R from the upper side of the anchor as shown in FIG. Manipulate. Due to the upward pulling, the connection main body pieces 21 and 21 cannot be rotated further because the angle A formed with respect to the fixed claw portion 3 cannot be further increased. Rotate.
[0033]
  By the rotation of the operation member 23 with respect to the connection main body pieces 21, 21, the sliding member 22 slides in the direction in which the sliding member storage portion 21 a retreats from the support portion 4 via the connecting member 24. The member attachment part 40 comes out of the recess 43 and the locking by the contact between the sliding member 22 and the contact part 42 is released. As a result, the restriction on the rotation range of the connection main body pieces 21, 21 that has been controlled so that the angle A formed by the connection main body pieces 21, 21 and the fixed claw portion 3 does not increase to about 45 ° or more is released. The main body pieces 21 and 21 start to rotate with respect to the bag main body 1, and the angle A formed by the connection main body pieces 21 and 21 and the fixed claw portion 3 becomes an obtuse angle of 90 ° or more as shown in FIGS. Rotate until By this rotation, the pulling force from the rope R applied to the fixed claw portion 3 acts greatly in the direction along the longitudinal direction of the fixed claw portion 3, and the fixed claw portion 3 can be easily removed from the fixed member H. , You can remove the bag.
[0034]
  When the sliding member 22 comes out of the recess 43 and the connection main body pieces 21 and 21 are rotatable with respect to the bag main body 1, the operation member 23 and the connection main body pieces 21 and 21 tend to be in a straight line. However, since the sliding member 22 abuts on the guide portion 44 and cannot slide to the support portion 4 side, both the operation member 23 and the connection main body pieces 21 and 21 rotate backward while maintaining the bent state. The connection main body pieces 21 and 21 increase the angle A with respect to the fixed claw portion 3.
[0035]
  Then, as described above as the second rotation, the support portion 4 (more specifically, the support portion 4 and the connection member 2 attached to the support portion 4 via the connection member attachment portion 40)Since it can be rotated around the axis extending in the front-rear direction with respect to the fixed claw portion 3, as shown in FIG. 17, a ridge is placed on the inclined seabed and the fixed claw portion 3 is not horizontal. Even in the case of FIG.Arrow TAs shown in FIG. 17, the support part 4 can be rotated, and the connection main body pieces 21 and 21 connected to the support part 4 can be vertically applied as shown in FIG. The hook can be easily removed from the fixed member H.
  Here, as described above, since the support portion 4 can be rotated with respect to the fixed claw portion 3 about the axis extending in the front-rear direction, as shown in FIG. Even if the fixed claw portion 3 is not horizontal, the support portion 4 can be rotated T as shown in FIG. 8, and the connection main body piece 21 connected to the support portion 4, As shown in FIG. 17, it is possible to apply a straight force to the 21 in the vertical direction, and it is possible to easily remove the heel from the fixed member H.
[0036]
  In the first embodiment of the present invention, the sliding member 22 and the connecting member 24 are integrated as described above. However, as shown in FIG. Since the side is wide and the rear end side is narrow, the sliding member 22 can slide without any trouble with respect to the sliding member storage portion 21a, and the same operation as in the second embodiment can be achieved.
  Thereby, compared with 2nd Embodiment, since the direction of 1st Embodiment can abbreviate | omit the connection part 22a of the sliding member 22, the pin for connection, etc., it can reduce the manufacturing cost of a collar, It is advantageous.
[0037]
  In addition, when the heel is used again after removing the heel, it is submerged in the seabed in the state shown in FIG. 10 in which the angle A formed by the connecting body pieces 21 and 21 and the fixed claw portion 3 is an obtuse angle. As described above, the rope R is pulled by moving the ship or the like. At that time, the operating member 23 tries to be aligned with the connecting body pieces 21 and 21 by the pulling force of the rope R, and the sliding member 22 tries to slide toward the support portion 4 side of the rod body 1. Since the member 22 is in contact with the guide portion 44 of the support portion 4 formed in a circular arc concentric with the shaft 41, the sliding member 22 does not slide with respect to the connection main body pieces 21, 21. Is guided along the guide portion 44 while maintaining the above. Accordingly, the connection main body pieces 21 and 21 maintain a state in which the connection main body pieces 21 and 21 can rotate toward the claw portions 31 and 31 with respect to the rod main body 1 even when the angle A formed with the fixed claw portion 3 becomes an obtuse angle. The connection main body pieces 21, 21 are rotated toward the claw portions 31, 31 with respect to the bag main body 1 by pulling the R, and the angle A is reduced with respect to the fixed claw portion 3. When the sliding member 22 matches the recess 43, the operating member 23 tries to be in a straight line with the connection main body pieces 21 and 21, and the sliding member 22 slides toward the support portion 4 side of the bag main body 1 to form the recess. 43, the state shown in FIG.
[0038]
  In addition, when the rope R is pulled by sinking the sea bream on the seabed, the operation member 23 is moved to the claw of the fixed claw 3 with the claw parts 31 of the fixed claw 3 being on the rear side as shown in FIG. Although it may be pulled in a direction opposite to the portions 31 and 31, even if such a state occurs, the connection main body pieces 21 and 21 and the bag main body 1 rotate with each other. The main body 1 rotates the seabed around the rear end side opposite to the claw portions 31 and 31 of the fixed claw portion 3, and the claw portions 31 and 31 of the fixed claw portion 3 are moved as shown by broken lines in FIG. Come forward. When the fixed claw portion 3 comes to the front side, the sliding member 22 matches the concave portion 43 and enters the concave portion 43, and the state shown in FIG.
[0039]
  The contact portions 42 and 42 of the support portion 4 are not limited to those of the first and second embodiments. For example, as shown in FIG. 13, the side surfaces of the rod-like bodies 5 and 5 may be used as the contact portions 42 and 42. In this case, the guide portion 44 is not provided.
[0040]
  Further, the guide portion 44 of the support portion 4 is not limited to a circular arc shape concentric with the shaft 41, but is formed in a linear shape whose distance gradually decreases from the rear shaft 41, for example, as shown in FIG. 14. Things can be used. Furthermore, the configuration is not limited to the configuration in which the guide portion 44 is provided, and may be a configuration in which the guide portion 44 is not provided as shown in FIG. However, when the guide portion 44 is formed in a straight line or not provided, for example, as shown by a dotted line in FIG. 14, after the sliding member 22 comes out of the concave portion 43 of the connection member mounting portion 40, the support portion The sliding member 22 slides to the support portion 4 side when the connection main body pieces 21 and 21 are rotated to the rear side. If it will be in this state, it will become difficult to rotate the connection main body pieces 21 and 21 ahead with respect to the support part 4, As a result, when using a scissors again, the operation member 23 is connected with the connection main body piece 21 by hand. , 21 to rotate the sliding member 22 to the side opposite to the support portion 4, and then rotate the connecting body pieces 21, 21 to the front side relative to the support portion 4 to slide. The member 22 must enter the recess 43. Therefore, if the guide portion 44 is formed in an arc shape concentric with the shaft 41 as in the first and second embodiments, the scissors can be used again without such an operation. It is advantageous.
[0041]
  Further, the position of the guide portion 44 is not limited to the position where the angle A formed by the connection main body pieces 21 and 21 and the fixed claw portion 3 is approximately 45 °, but may be any range as long as the angle A formed by both of them forms an acute angle. It can be changed as appropriate.
[0042]
  Moreover, the kind of ship in which the rod of this invention is used is not specifically limited, It can use for various things, such as a leisure boat, a small ship, or a fishing boat.
[0043]
【The invention's effect】
  As described above, according to the present invention, the fixing claws 3 can be firmly fixed by the regulating means 22 and 42 so as to bite the fixed member H into the rock or the like on the seabed. On the other hand, when removing the anchor fixed to the seabed, if the connecting member 2 is pulled by the restriction release means 23, 24, the fixing claw 3 can be easily removed from the member to be fixed H, and the anchor fixed to the seabed. Can be easily removed.
[0044]
  Further, when removing the anchor that has been fixed by biting the fixed claw portion 3 into the fixed member H on the seabed, the operation member 23 may be rotated with respect to the connection body piece 21 by pulling the rope R from the ship. Thereby, the latch by contact | abutting with the contact part 42 and the sliding member 22 can be removed, and the angle A which the connection member 2 makes with respect to the fixed nail | claw 3 of the collar main body 1 is made from an acute angle to an obtuse angle. Can do. Therefore, the anchor fixed to the seabed can be easily removed.
[0045]
  And since the connection member 2 can rotate centering on the longitudinal axis with respect to the fixed nail | claw part 3 of the main body 1, the ridge is put on the inclined seabed etc., and the fixed claw part 3 is horizontal. Even if it is not, etc., the connecting body piece 21 can be set in the vertical direction, and a force can be applied straight, and the hook can be easily removed from the fixed member H.
