(57) [Summary] [Purpose] An anchor for horizontal mooring that has a main anchor part and an auxiliary anchor part can secure a lateral mooring state, and provides an anchor that exerts a great mooring force in mooring sand. thing. A mooring chain 4 engages with a main anchor portion 1 at or near the center thereof, while a mooring chain 25 is attached to an auxiliary anchor portion 2 and a distal end portion of an arm distant from the center through a swing link 25. The pulling force from the mooring chain 4 which accompanies the movement of the ship causes the swing link 2 to engage.
A large component force is exerted in the main anchor portion direction via 5 to act on the main anchor portion and the auxiliary anchor portion 2 at the same time, and due to the component force in the main anchor portion direction, a normal mooring of the anchor of the mooring chain is performed. Even at an angle or more, the mooring action in the substantially horizontal direction from the main anchor portion to the auxiliary anchor portion along the shank member is exhibited.
Description
【0001】[0001]
本考案は砂地係留に優れる横置き係留用アンカーに関するものである。 The present invention relates to a horizontal mooring anchor which is excellent in mooring sand.
【0002】[0002]
砂地係留に対しては図4に示すように、アンカーが海底で横置きされるように フック爪部Fから直立するシャンクSの先端にT字形状にストックTが形成され るとともに、そのストック部Tに係留チェーンCを固定し、海底面でストックT が止まると(図4(a)参照)、フック爪部Fが海底に突き刺さるとともにシャ ンクSが水平に倒れるようになっている(図4(b)参照)。 As shown in Fig. 4, for mooring sandy ground, a T-shaped stock T is formed at the tip of the shank S standing upright from the hook claw F so that the anchor is laid horizontally on the seabed. When the mooring chain C is fixed to T and the stock T stops at the bottom of the sea (see Fig. 4 (a)), the hook claw F sticks into the bottom of the sea and the shank S falls horizontally (Fig. 4). (See (b)).
【0003】[0003]
しかしながら、係留チェーンCに引っ張り力がかかると、ストックTが起き上 がり、フック爪部Fと海底との引っ掛かりに係留力が左右されるため、砂地等の 場合は充分な係留力を発揮することができないという問題点かある。 そこで、本考案者は上記問題点を解決するために、上記ストックTに代えて補 助アンカーを併設して係留力の増大を図ることに着目したが、従来と同様にシャ ンク部材の他端に係留チェーンを直接取り付けると、係留チェーンCに引っ張り 力がかかると、補助アンカー部が起き上がり、横置き状態が確保できないことが 分かった。 本考案はシャンク部材を介して主アンカー部と補助アンカー部とを併設した横 置き係留用アンカーにおいて横置き係留状態を確保することができる構造を提供 することを目的とする。 However, when tension is applied to the mooring chain C, the stock T rises up and the mooring force is affected by the hooking of the hook claw F with the sea bottom. There is a problem that you can not do. In order to solve the above problems, the inventor has focused on increasing the mooring force by installing auxiliary anchors instead of the stock T. However, the other end of the shank member is similar to the conventional one. It was found that when the mooring chain is directly attached to the mooring chain C, when a tensile force is applied to the mooring chain C, the auxiliary anchor part rises up and the horizontal installation state cannot be secured. An object of the present invention is to provide a structure capable of ensuring a horizontal mooring state in a horizontal mooring anchor having a main anchor portion and an auxiliary anchor portion provided side by side via a shank member.
【0004】[0004]
本考案はシャンク部材の両端に併設した主アンカー部と補助アンカー部とを極 力横置き状態とするためには、主アンカー部と補助アンカー部に対する係留チェ ーンの係合関係が重要であることに着目してなされたもので、 シャンク部材3の一端からその周囲に放射状に延びる複数のアーム11を有す る主アンカー部1と、シャンク部材3の他端からその周囲に放射状に延びる上記 主アンカー部のアーム11より短い複数のアーム21を有する補助アンカー部2 とを備え、更に係留チェーン4が上記主アンカー部1においてその中心またはそ の近傍に係合し、次いでシャンク部材3に沿って延び、上記補助アンカー部2に おいて中心から外方に離れたアーム23の先端部に揺動リンク25を介して係合 して上記主アンカー部1および補助アンカー部2を同時に牽引するように取り付 けられていることを特徴とするものである。 In the present invention, the engagement relationship of the mooring chains with respect to the main anchor portion and the auxiliary anchor portion is important in order to place the main anchor portion and the auxiliary anchor portion juxtaposed on both ends of the shank member in the laterally placed state as much as possible. The main anchor portion 1 having a plurality of arms 11 radially extending from one end of the shank member 3 to the periphery thereof, and the main anchor portion 1 radially extending from the other end of the shank member 3 to the periphery thereof. An auxiliary anchor portion 2 having a plurality of arms 21 shorter than the arm 11 of the main anchor portion, and further a mooring chain 4 engages at or near its center in the main anchor portion 1 and then along the shank member 3. The auxiliary anchor portion 2 and the distal end portion of the arm 23 distant from the center of the auxiliary anchor portion 2 through the swing link 25 to engage with the main anchor portion 1 and the auxiliary anchor portion 2. And it is characterized in that it kicked Installing to pulling the anchor section 2 at the same time.
【0005】[0005]
本考案によれば、係留チェーン4が主アンカー部1に対しその中心またはその 近傍において係合する一方、補助アンカー部2とその中心より外方に離れたアー ムの先端部に対し揺動リンク25を介して係合するため、船舶移動に伴う係留チ ェーン4からの引っ張り力は揺動リンク25を介して主アンカー部方向に大きく 分力され、主アンカー部と補助アンカー部2とに同時に作用するだけでなく、上 記主アンカー部方向への分力により、係留チェーンのアンカーに対する通常の係 留角度(30°前後)以上の45〜60°でも主アンカー部からシャンク部材に 沿って補助アンカー部に至る略水平方向への係留作用が発揮される結果、横置き 係留が確保され、砂地に対する係留効果が著しく増大することになる。 他方、係留チェーン4を垂直方向に引き上げると、補助アンカー部2が起き上 がった後主アンカー部1が引上げられるので、引上げ作業に支障を来すことはな い。 このような主アンカー部と補助アンカー部とからなるアンカーは運搬および収 納に際し、嵩張るので、バー部材3を介して併設された主アンカー部1と補助ア ンカー部2とが分離可能であるのが好ましい。 According to the present invention, the mooring chain 4 is engaged with the main anchor portion 1 at or near the center thereof, while the swing link is attached to the auxiliary anchor portion 2 and the tip of the arm that is spaced outward from the center. 25, the pulling force from the mooring chain 4 accompanying the movement of the ship is largely divided in the direction of the main anchor portion via the swing link 25, and the main anchor portion and the auxiliary anchor portion 2 are simultaneously subjected to the pulling force. In addition to acting, the component force in the direction of the main anchor described above assists along the shank member from the main anchor even at 45 to 60 ° above the normal mooring angle (about 30 °) with respect to the anchor of the mooring chain. As a result of exerting a mooring effect in a substantially horizontal direction up to the anchor part, lateral mooring is secured and the mooring effect on sand is significantly increased. On the other hand, when the mooring chain 4 is pulled up in the vertical direction, the main anchor portion 1 is pulled up after the auxiliary anchor portion 2 is raised, so that there is no hindrance to the pulling work. Since the anchor composed of the main anchor portion and the auxiliary anchor portion is bulky during transportation and storage, it is possible to separate the main anchor portion 1 and the auxiliary anchor portion 2 provided side by side via the bar member 3. Is preferred.
【0006】[0006]
図1は本考案に係る横置き係留用アンカーの組立分解斜視図であり、主アンカ ー部1と補助アンカー部2とはシャンク部材3を介して両端に併設されている。 FIG. 1 is an exploded perspective view of an anchor for horizontal mooring according to the present invention, in which a main anchor portion 1 and an auxiliary anchor portion 2 are provided side by side via a shank member 3.
【0007】 上記主アンカー部1は図面上、シャンク部材3の先端部において90度の角度 をなして四方に延び、先端がほぼ45度上方に屈曲した4本の長さL1のアーム 11を有し、その先端部に5角形の爪ブレード12がシャンク部材3に対して略 垂直からやや内方に傾斜して取り付けてある。 他方、上記補助アンカー部2は上記シャンク部材3の後端部において同じく9 0度の角度をなして四方に延びる上記主アンカー部のアームより短い長さL2の アーム21を有し、その先端部に1個を除いて上記シャンク部材3に対して垂直 方向に爪ブレード22が取り付けてある。In the drawing, the main anchor portion 1 has four arms 11 each having a length L1 and extending in four directions at an angle of 90 degrees at the tip of the shank member 3 and having the tip bent upward by about 45 degrees. Then, a pentagonal claw blade 12 is attached to the tip end portion of the shank member 3 while being inclined slightly inward from substantially vertical. On the other hand, the auxiliary anchor portion 2 has an arm 21 having a length L2 shorter than that of the arm of the main anchor portion, which extends in all directions at the rear end portion of the shank member 3 and also forms an angle of 90 degrees, and its tip portion Claw blades 22 are attached to the shank member 3 in the vertical direction except one.
【0008】 上記シャンク部材3は主アンカー部1の近傍において分離され、その短辺部3 1と長辺部32とが嵌め合わせて組み立てられ、ネジ33にて固定できるように なっている。The shank member 3 is separated in the vicinity of the main anchor portion 1, and the short side portion 31 and the long side portion 32 are fitted and assembled together, and can be fixed with a screw 33.
【0009】 上記係留チェーン4は主アンカー部1において、上記シャンク部材3の短辺部 31に一端が取り付けられ、そしてシャンク部材3の長辺部32に沿って延び、 補助アンカー部2において、その爪ブレード22の取り付けられていないストッ ク21の外側端にピン24にて抜け止めされた嵌合部材23の先端に揺動リンク 25を介して係合し、上方に引き上げられている。The mooring chain 4 has one end attached to the short side portion 31 of the shank member 3 in the main anchor portion 1 and extends along the long side portion 32 of the shank member 3 in the auxiliary anchor portion 2. The outer end of the stock 21 to which the claw blade 22 is not attached is engaged with the tip of a fitting member 23, which is retained by a pin 24, via a swing link 25, and is pulled upward.
【0010】 したがって、上記アンカーは海中に投げ入れると、主アンカー部1が海底面に 停止すると、水平に倒れ、図2に示すように横置きになり、主アンカー部1の爪 ブレード12だけでなく、補助アンカー部2の爪ブレード22も海底に食い込む ことになる。船舶移動に伴う係留チェーン4からの引っ張り力は揺動リンク25 を介して主アンカー部方向に大きく分力され、主アンカー部1と補助アンカー部 2とに同時に作用するだけでなく、上記主アンカー部方向への分力は係留チェー ン4のアンカーに対する係留角度45°〜60°でも主アンカー部1からシャン ク部材3に沿って補助アンカー部2に至る矢印方向の係留力が発揮させ、海底が 砂地である場合でも大きな係留効果が発揮される。Therefore, when the above anchor is thrown into the sea, when the main anchor part 1 stops at the sea bottom, it falls horizontally and becomes horizontal as shown in FIG. 2, and not only the claw blade 12 of the main anchor part 1 but also The claw blade 22 of the auxiliary anchor part 2 will also bite into the seabed. The pulling force from the mooring chain 4 accompanying the movement of the ship is largely divided in the direction of the main anchor portion via the swing link 25, and not only acts on the main anchor portion 1 and the auxiliary anchor portion 2 at the same time, but also the main anchor portion. Even if the mooring angle of the mooring chain 4 with respect to the anchor is 45 ° to 60 °, the mooring force in the direction of the arrow from the main anchor part 1 to the auxiliary anchor part 2 along the shank member 3 is exerted, and the component force in the direction of the sea bottom Even if it is sandy land, a great mooring effect is exhibited.
【0011】 他方、運悪く、図3(a)に示すように、主アンカー部1の爪ブレード12が 岩礁Rに食い込んで係留されるとすると、引き上げ時には矢印A方向に係留チェ ーン4が引っ張られるため、上記嵌合部材23のピン係合が破断解除され、係留 チェーン4は補助アンカー部2から離脱することになる(図3(b)参照)。 離脱した係留チェーン4は主アンカー部1側に到り、矢印B方向に引っ張られ るため(図3(c)参照)、岩礁Rに食い込んだ爪ブレード22は食い込み方向 とは逆方向に引かれることになって抜き上げられる(図3(d)参照)。On the other hand, unfortunately, as shown in FIG. 3 (a), if the claw blade 12 of the main anchor portion 1 bites into the reef R and is moored, the mooring chain 4 moves in the direction of arrow A at the time of pulling up. Because of the pulling, the pin engagement of the fitting member 23 is released and the mooring chain 4 is disengaged from the auxiliary anchor portion 2 (see FIG. 3 (b)). The detached mooring chain 4 reaches the main anchor portion 1 side and is pulled in the direction of arrow B (see FIG. 3 (c)), so that the claw blade 22 biting into the reef R is pulled in the direction opposite to the biting direction. In some cases, it is pulled up (see FIG. 3 (d)).
【0012】 上記実施例では係留チェーン4を使用したが、係留ロープを使用してもよく、 本考案の範囲を逸脱することなく、変形容易である。Although the mooring chain 4 is used in the above-described embodiment, a mooring rope may be used, and it is easily deformed without departing from the scope of the present invention.
