Steering of a plurality of rudder 10 attached to the stern of a ferry 9 (bass of catamaran) enables stable movement using flow without using power. By attaching a kingpin 7 from the bow of the ferry 9 to about one-third of the length of the ship, the width of movement is much wider than that of a ferry using a flow using a conventional rope. Since it is based on a catamaran, it can be adapted to the depths of the river and is stable. Because it does not use fuel, it does not emit CO2 and is environmentally friendly. In the model ship experiment, the rope was able to move up to 45 degrees upstream.

従来のロープを使い川の流れを利用した渡し船はロープを渡し船の先端に付けけん引する構造のため移動幅が狭く又大型船化が困難であった。   A conventional ferry using the river flow using a rope has a structure in which the rope is attached to the tip of the ferry and the movement width is narrow and it is difficult to make a large ship.

第1の発明は、岸の堅固な固定物に取り付けたキングピンと、また船の船首から船の長さの３分の１付近の甲板上に取り付けたキングピンとを可動連結具、ヨリモドシ、けん引綱を用いて連結する構造とした渡し船。   In the first invention, a king pin attached to a rigid fixed object on the shore and a king pin attached to a deck near the third of the length of the ship from the bow of the ship are connected to the movable connector, the twister, the towing line. A ferry that is structured to be connected using

第2の発明は、第１の発明においての渡し船を水の流れを利用して移動させるには、船
は双胴船とし、左右の船体の船尾にそれぞれの方向舵を設け、該左右の方向舵は連結棒の手段により連結して回動する舵とした。舵は船の方向と安定性をつかさどる。 In the second invention, in order to move the ferry in the first invention using the flow of water, the ship is a catamaran, and the respective rudder is provided at the stern of the left and right hulls. The rudder is connected and rotated by means of a connecting rod. The rudder is responsible for the direction and stability of the ship.

本発明は動力を必要とせず水の流れを利用し対岸に接岸又元の岸に戻る事ができる渡し船である。そして船の船首から船の長さの３分の１付近にキングピンを取り付けて、けん引する事により移動幅が格段に広くなった。また連動した舵を付けた事により操縦が簡単で、河川の流れにも対応できる。船は双胴船で安定している。大型船化をも可能にしている。この渡し船は燃料を使わずＣＯ2を出さない環境にやさしいものである。本発明の渡し船は経済性、安全性に優れ、渡し船以外にも利用効果は大きく期待できるものである。また川の中に堅固な固定物を作る事が可能であれば、その利用価値は大きく躍進できることが期待できる。そして図１０の様に空中ケーブルを利用すれば川幅の制限も大きく緩和されよう。   The present invention is a ferry that can return to the opposite shore or return to the opposite shore using water flow without requiring power. And by attaching a kingpin from the bow of the ship to around one-third of the length of the ship and towing it, the range of movement became much wider. In addition, it is easy to control due to the interlocked rudder, and can handle the flow of rivers. The ship is a catamaran and is stable. Large ships can also be made available. This ferry is environmentally friendly and uses no fuel and emits no CO2. The ferry of the present invention is excellent in economic efficiency and safety, and the use effect can be greatly expected in addition to ferry. In addition, if it is possible to make a solid fixed object in the river, it can be expected that the utility value will be greatly improved. And if the aerial cable is used as shown in Fig. 10, the river width limitation will be greatly relaxed.

本発明は上記課題を解決するものであるが、本発明の構成及び使用時の作用について説
明する。 The present invention solves the above problems, but the configuration of the present invention and the operation during use will be described.

本発明の使用形態は、岸Ｂの堅固な固定物Ｃにキングピン１を取り付ける。そのキング
ピン１に可動連結具2を結合させる。可動連結具2はキングピン1と結合されても左右に回転できる様になっている。けん引綱4のねじれを防ぐ為ヨリモドシ3を入れそのヨリモドシ3からけん引綱4へとつなぐ。けん引綱4は船の方に入り船側のヨリモドシ5へとつながれ可動連結具6へと続く。この可動連結具6は船のキングピン7と結合されるがこれもまた左右に回転できる構造となっている。本発明の船に船首から船の長さの３分の１付近に取り付けたキングピン7をけん引する事で移動幅が格段に広くなった。船は双胴船でそれぞれの船尾に方向舵１０を設けその左右の方向舵１０は連結棒１１でつながれ連動する構造となっている。本発明の渡し船９は船尾の連動舵の操作で水の流れを利用して、対岸に到達し又元の岸に戻る事ができる。なお、船の形が前後左右が対称の作りであってその中心と重心がほぼ同一であれば船首から３分の１付近が最良であるが、船の中心と重心がずれている場合は船首から４分の１から２分の１未満で良い位置を見つけるのが船の性能を充分に発揮させる事になる。船首から２分の１近くになると少しの舵取りでも急激な方向変換をするので接続各部に大きな負荷がかかるので避けなければならない。 In the usage mode of the present invention, the king pin 1 is attached to a solid fixed object C on the shore B. The movable connector 2 is coupled to the king pin 1. The movable connector 2 can be rotated left and right even when coupled to the kingpin 1. In order to prevent twisting of the towline 4, insert the twister 3 and connect it from the twister 3 to the towline 4. The towing line 4 enters the ship and is connected to the warping 5 on the ship side and continues to the movable connector 6. This movable connector 6 is connected to the kingpin 7 of the ship, and this is also structured to be able to rotate left and right. By moving the kingpin 7 attached to the ship of the present invention from the bow to the vicinity of one-third of the length of the ship, the movement width is greatly widened. The ship is a catamaran, and a rudder 10 is provided at the stern of each ship. The left and right rudder 10 are connected by a connecting rod 11 and interlocked. The ferry 9 of the present invention can use the flow of water by the operation of the stern interlocking rudder to reach the opposite bank and return to the original bank. If the shape of the ship is symmetrical in the front, rear, left and right, and its center and center of gravity are almost the same, it is best around 1/3 from the bow. Finding a good position in a quarter or less than a half will make the ship perform well. If it is close to a half from the bow, it will change direction suddenly even with a small amount of steering.

以下、本発明について図面を参照にしながら、主に、本発明の構成及び使用時の作用に
ついて説明する。図1の状態は渡し船が左の桟橋に停船を維持し続けている状態である。 Hereinafter, the configuration of the present invention and the operation during use will be mainly described with reference to the drawings. The state in Fig. 1 is the state where the ferry continues to stop at the left pier.

図1においては岸Ｂの堅固な固定物Ｃに取り付けたキングピン1に可動連結具2を連結、可動連結具2は左右に回転できるものでその可動連結具2にヨリモドシ３をつなぐ、ヨリモドシ３にけん引綱４を連結した物である。けん引綱４は岸Ｂの堅固な固定物Ｃと渡し船９のキングピン７とをつなぐ物でロープ、ワイヤー等がある。船が大きくなれば岸Ｂの堅固な固定物Ｃと同様にけん引綱４の強度も増す必要がある。又、川幅が広くなれば対岸への距離が大きくなり船の移動幅もそれなりに必要になり必然的にけん引綱４の長さも長くなってくる。長くなればヨリモドシも必要になるだろう。可動連結具６は左右に回転できる物でキングピン７と連結されてその取り付け位置は最も重要で本発明の発想の原点である。渡し船９は双胴船を基本としている。方向舵１０は双胴船の船尾にそれぞれの方向舵１0を設け連結棒１1により連結され連動する。双胴船Ｒ船体１３は川上に向かって右側の船体を指す。双胴船Ｌ船体１４は川上に向かって左側の船体を指す。Ａは水流を、Ｂは岸、Ｓは桟橋をあらわしている。図1は渡し船が左斜めになっており船体の右側に水流圧を受けて左へ押され桟橋に押し付けられている状態である。この時の方向舵１０は右向きで停船を維持し続けている。   In FIG. 1, a movable connector 2 is connected to a king pin 1 attached to a rigid fixed object C on the shore B, and the movable connector 2 can be rotated to the left and right. A towing line 4 is connected. The towing line 4 is a thing that connects a rigid fixed object C on the shore B and a king pin 7 of a ferry 9 and includes a rope, a wire, and the like. As the ship grows larger, the strength of the towing line 4 needs to increase as well as the solid fixed object C on the shore B. In addition, if the river width becomes wider, the distance to the opposite shore increases, and the width of the ship is required accordingly, and the length of the towing line 4 is inevitably increased. If it gets longer, you will need a twist. The movable connector 6 is connected to the king pin 7 and can be rotated left and right, and its mounting position is the most important and is the origin of the idea of the present invention. The ferry 9 is basically a catamaran. The rudder 10 is provided with a respective rudder 10 at the stern of the catamaran and is connected and linked by a connecting rod 11. Catamaran R hull 13 points to the right hull toward the river. The catamaran L hull 14 points to the left hull toward the river. A shows the water flow, B shows the shore, and S shows the pier. Fig. 1 shows a state where the ferry is tilted to the left and is subjected to water pressure on the right side of the hull and pushed to the left and pressed against the pier. At this time, the rudder 10 keeps the stop in the right direction.

図２はキングピン1と可動連結具2、ヨリモドシ３からけん引綱４の側面図である。岸Ｂの堅固な固定物Ｃに取り付けた物と、船の船首から３分の１付近の甲板８上に取り付けた物とはほぼ同じ物を使用し左右に回転出来る様になっている。使う材質は船が大きくなれば負荷が大きくなりおのずと強度を増す必要がある。   FIG. 2 is a side view of the towing rope 4 from the king pin 1, the movable connector 2, and the twister 3. The thing attached to the solid fixed thing C of the shore B and the thing attached on the deck 8 near 1/3 from the bow of a ship can be rotated to right and left using the substantially same thing. The material used needs to increase its strength naturally as the ship becomes larger.

図３は渡し船９（双胴船）の後方から見た図である。中心線延長にキングピン７があり左右の船体１4、船体１3の後方に方向舵１０が方向舵回転軸１２に固定されつつ船体後部に取り付けられている。左右の方向舵１０は連結棒１１の手段により連結し、該方向舵１０を連動させて回動するようになっている。   FIG. 3 is a view of the ferry 9 (catamaran) as seen from the rear. There is a kingpin 7 at the center line extension, and a rudder 10 is attached to the rear part of the hull while being fixed to a rudder rotating shaft 12 behind the left and right hulls 14 and 13. The left and right rudder 10 are connected by means of a connecting rod 11, and the rudder 10 is rotated in conjunction with it.

図4は船体後部に取り付けられた連動舵を上から見た平面図である。舵２０は方向舵回転軸に直結、舵２０は小さくても良いこの船の操作がしやすい点を説明する。舵２０は少しずつ切るのが大切まず舵２０を少し切る、方向舵１０に少しの水流圧を受けるすると船尾が少し動くその時点で方向舵１０は水流Ａと平行になり方向舵１０に受ける水の抵抗がほとんど無くなってしまうからである。一度に大きく舵２０を切ろうとしない事が操作の大切なところである。連結棒１１は水に浸からない様に上部に付ける必要がある。連結棒１１は小型船向きと言えよう。   FIG. 4 is a plan view of the interlocked rudder attached to the rear of the hull as seen from above. The point that the rudder 20 is directly connected to the rudder rotation shaft and the rudder 20 may be small will be described. It is important to turn the rudder 20 little by little. First, the rudder 20 is turned slightly. When the rudder 10 receives a little water flow pressure, the stern moves slightly. At that point, the rudder 10 becomes parallel to the water flow A and the resistance of the water received by the rudder 10 is low. Because it almost disappears. It is important to not turn the rudder 20 large at a time. The connecting rod 11 needs to be attached to the upper part so as not to be immersed in water. It can be said that the connecting rod 11 is suitable for small ships.

図５は連動舵の他の方法として、左右の方向舵回転軸１２を同じ回転するように連結連動させる方法もある。左右の方向舵回転軸１２の上部にスプロケット１８を付けチェーン１９で１周させて回動させる。これは大型船向き。   FIG. 5 shows another method of interlocking rudder in which the left and right rudder rotating shafts 12 are linked and interlocked so as to rotate in the same way. A sprocket 18 is attached to the upper part of the left and right rudder rotating shafts 12 and rotated around the chain 19 by one turn. This is for large ships.

図６は渡し船９（双胴船）を右から見た側面図である。注目すべきはキングピン７が船首から３分の１付近の甲板８上に付けられていることである。この支点はけん引されている力が一点に集中されており、舵取りの際の方向舵１０の圧力が敏感に伝わり船体の方向変換に素早く反応して向きを変えた途端に船体そのものが舵の働きをして、進むべき方向へと移動して行く。けん引綱４で注意すべき点は、船体に触れない様にする事と水面に着けない様にする事である。   FIG. 6 is a side view of the ferry 9 (catamaran) viewed from the right. It should be noted that the kingpin 7 is mounted on the deck 8 near one third of the bow. This fulcrum is concentrated in one point, and the pressure of the rudder 10 at the time of steering is transmitted sensitively, reacts quickly to the direction change of the hull and changes its direction as soon as the hull itself works as a rudder. Then move in the direction you want to go. The point to be noted in the towing line 4 is to avoid touching the hull and not to touch the water surface.

図７から図１０までを使って渡し船９を右に移動させる場合の説明をする。   The case where the ferry 9 is moved to the right will be described with reference to FIGS.

図７について、船尾につけた方向舵１０を左向きにさせる。水流Ａは方向舵１０の右
側に当たり方向舵１０は左へ押される力が加わりその方向舵１０は船尾に取り付けらている為、船尾が左へ、左へ移動し始める。図８では渡し船９本体がキングピン７を中心に右旋回を始める。右旋回を始めた船体は図９へと移り、水流Ａに対して右斜めになった船体は左側に大きな水流圧が当り、川下へ流される力が働くが、船体はけん引綱４で位置を保持し今度は船全体が舵の作用をし渡し船９そのものが舵の働きをして右へ、右へと移動する。そして図１０へと続き船体はけん引綱４で保持されつつ岸Bの堅固な固定物Ｃに取り付けられたキングピン１を中心にけん引綱４の長さで円を描く様に右へ、右へと移動、今度は川上へ、川上へと移動して行く。そして対岸へ到達できる。 In FIG. 7, the rudder 10 attached to the stern is turned to the left. The water stream A hits the right side of the rudder 10 and the rudder 10 is pushed to the left and the rudder 10 is attached to the stern, so the stern begins to move to the left and left. In FIG. 8, the main body of the ferry 9 starts to turn right about the kingpin 7. The hull that has started to turn right moves to FIG. 9, and the hull that is tilted to the right with respect to the water flow A receives a large water flow pressure on the left side, and the force that flows down the river works, but the hull is positioned at the towline 4. This time, the entire ship acts as a rudder, and the ship 9 itself moves as a rudder and moves to the right and to the right. Continuing to FIG. 10, the hull is held by the towing line 4, while the kingpin 1 attached to the rigid fixed object C on the shore B is centered on the right side of the towing line 4 and then to the right. Move, this time move upstream, then move upstream. And you can reach the opposite bank.

左へ移動する場合は、概ねその逆と考えれば良い。実験結果について図７から図８について方向舵１０の作用で船尾が左へ移動した後、右斜めになった船体に左側面に大きな水流圧が加わり、キングピン７を基点に川上側の船体左側面に３分の１の圧力があり、川下側に３分の２の圧力が加わり、方向舵１０の作用により船尾が左へ移動したにもかかわらず３分の２の圧力で船尾が押し戻されるのではないかと疑問が出て、模型船の実験では何の問題も無く右へ、右へ移動しました。船体のカーブの具合で川上側に当った水流Ａは左へと方向を変えて流れ川下側にはあまり当らないのではないかと考えられる。又流れに対して船の傾きが２５度以内で運行した方がけん引綱4に与える張力負荷が少なく感じられる。模型船の実験ではけん引綱4の角度が４５度以上になるほど川上へ移動した。   When moving to the left, the opposite is generally true. 7 to 8 As a result of the rudder 10, the stern is moved to the left by the rudder 10 and a large water flow pressure is applied to the left side of the hull that is tilted to the right. There is one third of the pressure, two thirds of the pressure is applied downstream, and the stern is not pushed back by two thirds even though the stern has moved to the left by the action of the rudder 10 I was questioned, and in the model ship experiment, I moved to the right and right without any problems. It is thought that the water flow A that hits the upper stream due to the curve of the hull changes direction to the left and does not hit the lower stream. In addition, it is felt that the tension load applied to the towline 4 is less when the ship is operated with the inclination of the ship within 25 degrees with respect to the flow. In the model ship experiment, the tow rope 4 moved to the upstream as the angle of the tow rope 4 became 45 degrees or more.

他の実施例について、図１１をもとに説明すると大型船化には不向きかも知れないが、川幅が広い所には有効。川岸の両側にケーブルタワー１７を建て空中ワイヤーケーブル１５を張り渡す。このケーブルに空中動滑車１６を通す。この空中動滑車16にヨリモドシ３をつけてけん引綱４へと続く、あとは本発明の渡し船９を連結して運航すれば良い。空中ワイヤーケーブル１５で注意する点はワイヤーにはある程度の緊張感を持った引っ張る力が必要でダラッとたるませてはいけない。   Other embodiments will be described with reference to FIG. 11 and may not be suitable for a large ship, but it is effective in a wide river. A cable tower 17 is built on both sides of the river bank, and an aerial wire cable 15 is stretched over. Pass the air pulley 16 through this cable. It is only necessary that the air moving pulley 16 is attached with the twist 3 and continues to the towing line 4, and then the ferry 9 of the present invention is connected and operated. The point to be careful of with the air wire cable 15 is that the wire needs a pulling force with a certain degree of tension and should not be loosened.
