この考案は、小型船舶用の軽量錨として近来著しく普及しているダンホース型 錨の構造の欠点を改良し、取扱い易い種々の構造に関するものである。 The present invention relates to various structures that are easy to handle by improving the drawbacks of the structure of the Dunhose type anchor which has been remarkably popular recently as a lightweight anchor for small ships.
【0002】[0002]
従来のダンホース型錨は図6〜図8に示すように左右に先細り形の羽根板を三 角形の左右垂直板で固定し、この間に錨アームを設け、左右垂直板を真横に貫通 する錨アーム軸により錨アームの後端を支承し、錨アームの先端に錨綱を保持す る輪環が取付けられている。そして左右垂直板の後端部上下には補強板が固定さ れている構造である。しかし、この補強板が垂直板後部の上下間隙を塞いでいる ので、錨アームの後方回動をこの約60度の位置で阻止している。そのため錨使 用に際しては錨の前方移動を助勢するので良いが、錨の先端が水中の岩礁などに 突きささった場合、錨アームが後方回動しようとしても、前記の位置以上に後方 回動できないので錨綱が切れたり、錨の引抜きができなくなり、止むなく錨を放 棄しなければならない事態が発生していた。そのためこれらの欠点を改良したダ ンホース型錨の出現が要望されている。 As shown in Figs. 6 to 8, the conventional Dunhose type anchor has tapered vane plates fixed to the left and right with triangular vertical plates, and an anchor arm is provided between them, and the anchor arm penetrates right and left vertical plates right next to each other. A ring supports the rear end of the anchor arm by means of a shaft and holds the anchor rope at the tip of the anchor arm. The reinforcing plates are fixed above and below the rear ends of the left and right vertical plates. However, since the reinforcing plate closes the vertical gap at the rear part of the vertical plate, the rearward rotation of the anchor arm is prevented at the position of about 60 degrees. Therefore, when using the anchor, it is good to assist the forward movement of the anchor, but if the tip of the anchor hits a reef in the water, even if the anchor arm tries to rotate backward, it cannot rotate backward beyond the above position. Because of this, the anchor rope was broken, the anchor could not be pulled out, and there was a situation where the anchor had to be abandoned without stopping. Therefore, there is a demand for the emergence of a Dunhose type anchor that improves on these drawbacks.

そこでこの考案は、上記のような従来型ダンホース型錨の欠点をなくすために 種々の改良を行い、引出し容易で使い易い改良形ダンホース型錨を提供すること を目的としている。 Therefore, the object of the present invention is to make various improvements in order to eliminate the above-mentioned drawbacks of the conventional Dunhose anchor, and to provide an improved Dunhose anchor that is easy to pull out and easy to use.
【0004】[0004]
上記の目的を達成するために、本考案の第1項としては左右垂直板の上下に取 付けられた補強板を取外し、垂直板後端の上下にコの字形固定具を取付けて支持 し、左右垂直板のほぼ中央部上下に巻紐溝を形設し、錨使用時には錨アームを該 溝の位置まで引上げ上下の溝に紐を巻き、これにより錨アームをこの位置に止め る構造。 又第2項として錨アームの下部にアーム軸と同心の円弧孔を形設し、さらに左 右垂直板に前記円弧孔を通り錨アーム軸と平行に割ピン支持軸を取付け、この軸 の一端と錨アーム軸との間に割ピンを貫通して割ピンを止め、錨使用中に錨アー ムが大きく反転回動する際には錨アームの円弧孔によって割ピンが切断される構 造。 次に第3項としては、左右垂直板間の後端に取付けたコの字形固定具上前後方 向に油圧シリンダを装設し、なお錨アームの後端部には凸部と凹部を交互に形設 しておき、錨アームが反転回動により凸部が油圧シリンダのピストン押棒に圧接 すると、油圧シリンダが作動して錨アームを前方へ押し戻す構造。 In order to achieve the above object, as the first aspect of the present invention, the reinforcing plates attached to the upper and lower sides of the left and right vertical plates are removed, and U-shaped fixtures are attached and supported on the upper and lower ends of the vertical plates to support them. A structure in which winding cord grooves are formed in the upper and lower parts of the center of the left and right vertical plates, and when the anchor is used, the anchor arm is pulled up to the position of the groove and the cord is wound in the upper and lower grooves, thereby stopping the anchor arm at this position. As the second term, an arc hole is formed in the lower part of the anchor arm concentric with the arm shaft, and a split pin support shaft is attached to the left and right vertical plates in parallel with the anchor arm shaft through the arc hole and one end of this shaft is attached. A structure that penetrates the split pin between the and the anchor arm shaft to stop the split pin, and the split pin is cut by the arc hole of the anchor arm when the anchor arm makes a large reversal rotation while using the anchor. Next, as the third item, a hydraulic cylinder is installed on the U-shaped fixture attached to the rear end between the left and right vertical plates, and the convex and concave portions are alternately arranged on the rear end of the anchor arm. When the convex portion comes into pressure contact with the piston push rod of the hydraulic cylinder when the anchor arm rotates in reverse, the hydraulic cylinder operates and pushes the anchor arm forward.

上記のように構成された改良形ダンホース型錨は、左右垂直板の上下に取付け られていた補強板を取外したため、錨アームは後方へも回動自在となったが、後 方へ90度以上に倒れると、錨を引張って水底に対する錨の利きが悪くなる。そ のため、垂直板の中央部上下に形設した巻紐溝へ紐を巻いたり、又割ピン支持軸 と割ピンによって錨アームが水平に対し60度以上に後方へ回動しないように保 持してダンホース型錨の姿勢を保持している。しかし潮流や風波の影響により船 が流され又は錨が動いて岩礁などに挟まれた場合には、錨綱を引いて錨アームを 強く上に引張り、これらの場合は錨アームにより巻紐を押し切ったり、割ピンを 切断して錨アームを後方へ回動し、錨を挟まれた岩礁などから後方へ引抜いて錨 を収容するものである。又油圧シリンダ装備の改良形錨においては、このような 非常の場合に錨綱を上に引いて錨アームを回動すると、下端の凹部がピストン押 棒を押し油圧シリンダが作動して錨アームの回動を助長して後方へ回動させるの で、前記同様に錨を後方に引抜いて脱出することができる。 In the improved Danhose anchor configured as described above, the reinforcing plates attached to the upper and lower sides of the left and right vertical plates were removed, so the anchor arm was also rotatable rearward, but at least 90 degrees backward When it falls down, it pulls the anchor and the anchor becomes less effective with respect to the bottom of the water. For this reason, the cord is wound in the winding cord grooves formed above and below the center of the vertical plate, and the split pin support shaft and split pin prevent the anchor arm from rotating backward more than 60 degrees with respect to the horizontal. Holds and holds the attitude of Dunhose type anchor. However, if the ship is swept away by the influence of tidal currents or wind waves or the anchor moves and is caught between reefs, pull the anchor rope and pull the anchor arm strongly upward.In these cases, the anchor arm pushes off the cord. Alternatively, the cotter pin is cut to rotate the anchor arm backwards, and the anchors are pulled out backwards from the reef where the anchors are sandwiched to accommodate the anchors. In an improved anchor equipped with a hydraulic cylinder, in such an emergency, when the anchor rope is pulled up and the anchor arm is rotated, the recess at the lower end pushes the piston push rod and the hydraulic cylinder operates to operate the anchor arm. Since the rotation is promoted to rotate it backward, the anchor can be pulled out backward and escaped in the same manner as described above.

実施例について図面を参照して説明すると、従来のダンホース型錨は図6にお いて、左右の羽根板を(1)、左右の垂直板を(2)、この垂直板を左右に貫通 する錨アーム軸(3)、錨アーム(5)錨アームの錨綱輪環(4)とし、左右の 垂直板の後部上下に補強板(R)を取付けて成るものである。次に改良形は先ず 垂直板の上下に取付けられた補強板(R)を取外し、垂直板(2)後端の上下に コの字形固定具(7)を取付けて支持し、左右に垂直板(2)のほぼ中央部の上 下に巻紐溝(8)を形設し、錨の使用時にはこの上下巻紐溝にわたって紐を巻き 、錨アームをこの位置に止めおく構造である。さらに第2改良形として錨アーム (5)の下部に錨アーム軸(3)と同心の円弧孔(6)を形設し、また左右垂直 板(2)に錨アーム軸(3)と平行で円弧孔(6)を貫通する割ピン支持軸(1 0)を取付け、この軸の一端と錨アーム軸(3)にわたる割ピン(9)を貫通し 、止めて成る構造である。さらに第3の改良形としては、コの字形固定具(7) の上下板の間に油圧シリンダ(C)を前後方向に装設し、また錨アーム(5)の 後端部に凸部(11),凹部(12)を交互に形設し、錨アーム(5)の反転回 動により凸部(11)が油圧シリンダ(C)のピストン押棒(P)に圧接すると 油圧シリンダ(C)が作動して錨アーム(5)を前方へ押し戻す構造である。 An embodiment will be described with reference to the drawings. A conventional Dunhose type anchor is shown in FIG. 6, in which the left and right vane plates (1), the left and right vertical plates (2), and the anchors that penetrate the vertical plates to the left and right. The arm shaft (3), the anchor arm (5) are the anchor rope rings (4) of the anchor arm, and the reinforcing plates (R) are attached to the upper and lower rear parts of the left and right vertical plates. Next, in the improved type, first, the reinforcing plates (R) attached to the upper and lower sides of the vertical plate are removed, and the U-shaped fixtures (7) are attached and supported on the upper and lower ends of the vertical plate (2) to support the vertical plate to the left and right. A winding cord groove (8) is formed in the upper and lower portions of the central portion of (2), and when the anchor is used, the cord is wound over the upper and lower winding cord grooves and the anchor arm is held at this position. Further, as a second improvement, an arc hole (6) concentric with the anchor arm shaft (3) is formed in the lower part of the anchor arm (5), and the left and right vertical plates (2) are parallel to the anchor arm shaft (3). The structure is such that a split pin support shaft (10) penetrating the circular arc hole (6) is attached, and a split pin (9) extending through one end of this shaft and the anchor arm shaft (3) is penetrated and stopped. Further, as a third improved form, a hydraulic cylinder (C) is installed in the front-rear direction between the upper and lower plates of the U-shaped fixture (7), and the convex portion (11) is provided at the rear end of the anchor arm (5). , The recesses (12) are alternately formed, and when the protrusion (11) is brought into pressure contact with the piston push rod (P) of the hydraulic cylinder (C) by the reverse rotation of the anchor arm (5), the hydraulic cylinder (C) operates. It is a structure that pushes the anchor arm (5) forward.

本考案は、以上説明したように構成されているので、以下記述のような効果を 奏するものである。 従来のダンホース型錨は、軽量で取扱い易く錨としての効用も果すので重宝さ れて普及されているが、一番の欠点は岩礁などに挟まれた時に錨アームが、上下 の補強板に邪魔されて後方へ回動しないので、錨綱を上に引張っても力が入らず に、綱が切れて錨を放棄しなければならなくなる事であった。 そのため本考案では、先ず補強板を取外し、そのために錨の効用が低下するこ とを防止するため、垂直板に錨止めの巻紐溝を形設し、紐を巻きつけてこの位置 で錨アームを止め、又割ピン支持軸を設けて錨アームを60度の位置に保持する ことに改造した。その為錨が岩礁に挟まれても、錨綱を引張り巻紐を切ったり、 割ピンを切断したりして錨を引抜き、錨の損失を防ぐことができるものである。 なお、油圧シリンダを装設して同様の効果を発揮することも可能で、本考案によ ってダンホース型錨は益々広く普及することを期待できる。 Since the present invention is configured as described above, it has the following effects. The conventional Dunhose-type anchor is popular because it is lightweight and easy to handle and also works as an anchor, but the main drawback is that the anchor arm interferes with the upper and lower reinforcing plates when it is sandwiched between reefs. Since it was not rotated backwards, even if the anchor rope was pulled upward, no force was applied and the rope broke and the anchor had to be abandoned. Therefore, in the present invention, firstly, the reinforcing plate is removed, and in order to prevent the effectiveness of the anchor from being lowered, a winding string groove for anchoring is formed on the vertical plate and the string is wound and the anchor arm is placed at this position. It was modified to hold the anchor arm at the 60 degree position with the split pin support shaft. Therefore, even if the anchor is caught on a reef, the anchor can be pulled out by pulling the anchor rope and cutting the winding cord or cutting the split pin to prevent loss of the anchor. It should be noted that it is possible to install a hydraulic cylinder to achieve the same effect, and it can be expected that the Dunhose type anchor will become more and more widely spread according to the present invention.
