後述する明細書及び図面の記載から、少なくとも以下の事項が明らかとなる。 At least the following matters will be clarified from the description of the specification and drawings described later.

一対の曳航ロープと、前記一対の曳航ロープの間に設けられ、被曳航船の船尾に取り付けられる船尾用部材と、を有する曳航部材と、
前記曳航ロープを挿通するための挿通部を有し、前記被曳航船に巻き付けるためのベルトと
を備えることを特徴とする曳航器材が明らかとなる。このような曳航器材によれば、被曳航船を安定して曳航可能である。 A towing member having a pair of towing ropes and a stern member provided between the pair of towing ropes and attached to the stern of the towed ship.
A towing equipment characterized by having an insertion portion for inserting the towing rope and a belt for winding around the towed ship will be revealed. According to such towing equipment, the towed vessel can be towed stably.

また、前記曳航ロープの端部には、他の部材に接続するための接続部が設けられていることが望ましい。これにより、曳航時に曳航ロープを結び付けるなどのロープワークが不要になるため、被曳航船への曳航器材の取り付けが容易になる。 Further, it is desirable that the end of the towing rope is provided with a connecting portion for connecting to another member. This eliminates the need for rope work such as tying the towing rope during towing, which facilitates the attachment of the towing equipment to the towed vessel.

前記船尾用部材は、網状の部材であることが望ましい。これにより、水が網目を通過できるため、曳航時に船尾用部材にかかる水流による負荷を軽減できる。 It is desirable that the stern member is a net-like member. As a result, water can pass through the mesh, so that the load due to the water flow applied to the stern member during towing can be reduced.

前記船尾用部材は、前記被曳航船のスターンアイに固定するための固定部を有することが望ましい。これにより、船尾用部材を被曳航船の船尾に固定でき、曳航部材の左右方向の位置ズレを抑制できる。 It is desirable that the stern member has a fixing portion for fixing to the stern eye of the towed ship. As a result, the stern member can be fixed to the stern of the towed ship, and the positional deviation of the towed member in the left-right direction can be suppressed.

前記船尾用部材は、下部を水中に沈めるための錘部を有することが望ましい。これにより、船尾用部材を被曳航船の船尾に取り付ける作業が容易になる。 It is desirable that the stern member has a weight portion for submerging the lower part in water. This facilitates the work of attaching the stern member to the stern of the towed vessel.

前記船尾用部材は、前記船尾用部材の上縁及び下縁を結び付けるための結索部を有することが望ましい。これにより、船尾用部材が船尾から外れにくくなる It is desirable that the stern member has a tying portion for connecting the upper edge and the lower edge of the stern member. This makes it difficult for the stern member to come off the stern.

前記ベルトは、前記被曳航船の左右の舷側にそれぞれ配置される複数の前記挿通部を有することが望ましい。これにより、様々な大きさの被曳航船に対して曳航ロープを適切な位置に配置できる。 It is desirable that the belt has a plurality of insertion portions arranged on the left and right sides of the towed vessel, respectively. This makes it possible to place the towing rope in an appropriate position for towed vessels of various sizes.

前記ベルトは、両端同士を結合するための結合部と、中央部を水中に沈めるためのベルト用錘部と、を有することが望ましい。これにより、ベルトの中央部を水中に沈め易くなり、ベルトを被曳航船に巻き付ける作業が容易になる。 It is desirable that the belt has a connecting portion for connecting both ends and a weight portion for a belt for submerging the central portion in water. As a result, the central portion of the belt can be easily submerged in water, and the work of winding the belt around the towed vessel becomes easy.

被曳航船にベルトを巻き付けること、
前記被曳航船の船尾に船尾用部材を取り付けるとともに、前記ベルトに設けられた挿通部に、前記船尾用部材から延び出る一対の曳航ロープを挿通すること、
を行うことを特徴とする曳航方法が明らかとなる。このような曳航方法によれば、被曳航船を安定して曳航可能である。 Wrapping the belt around the towed vessel,
Attaching a stern member to the stern of the towed ship and inserting a pair of towing ropes extending from the stern member into the insertion portion provided on the belt.
The towing method, which is characterized by performing the above, becomes clear. According to such a towing method, the towed vessel can be towed stably.

前記被曳航船の重心よりも前側に前記ベルトを配置することが望ましい。これにより、被曳航船を安定して曳航可能である。 It is desirable to arrange the belt in front of the center of gravity of the towed vessel. As a result, the towed vessel can be towed in a stable manner.

＝＝＝比較例＝＝＝
本実施形態の曳航器材を説明する前に、比較例の曳航方法について説明する。 === Comparative example ===
Before explaining the towing equipment of the present embodiment, the towing method of the comparative example will be described.

図９Ａ及び図９Ｂは、第１比較例の曳航方法の説明図である。第１比較例の曳航方法は、船舶（ここでは水上オートバイ）の船首部のバウアイに曳航ロープ（曳航索）を掛けて、船舶を曳航するものである。 9A and 9B are explanatory views of the towing method of the first comparative example. The towing method of the first comparative example is to hang a towing rope (towing rope) on the bow eye of the bow of the ship (here, a personal watercraft) to tow the ship.

一般的に、曳航ロープは、曳航船と被曳航船を足した長さの３倍以上の長さが必要であるとされている。このため、曳航ロープを被曳航船のバウアイに掛けると、この長さの曳航ロープの自重がバウアイにかかることになる。この結果、図９Ａに示すように、前方向に向かう力と下方向に向かう力（曳航ロープの自重）との合力がバウアイにかかるため、図９Ｂに示すように、被曳航船の船首を下げる方向に被曳航船に力がかかり、被曳航船の姿勢が崩れるおそれがある。なお、バウアイは重心から比較的離れて位置するため、曳航ロープの自重がバウアイにかかると、被曳航船にピッチ軸回りのモーメント力がかかることによって、被曳航船の船首を下げる方向に被曳航船に力がかかり易い。 Generally, it is said that the towing rope needs to be at least three times the total length of the towed vessel and the towed vessel. Therefore, when the towing rope is hung on the bow eye of the towed ship, the weight of the towing rope of this length is applied to the bow eye. As a result, as shown in FIG. 9A, the resultant force of the forward force and the downward force (the own weight of the towing rope) is applied to the bow eye, and therefore, as shown in FIG. 9B, the bow of the towed vessel is lowered. A force is applied to the towed vessel in the direction, and the attitude of the towed vessel may collapse. Since the bow eye is located relatively far from the center of gravity, when the weight of the towing rope is applied to the bow eye, a moment force around the pitch axis is applied to the towed vessel, and the towed vessel is towed in the direction of lowering the bow. It is easy to apply force to the ship.

特に、水上オートバイは、一般的に、被曳航船の船首が下がり易く構成されている。このため、被曳航船が水上オートバイの場合、第１比較例の曳航方法では、曳航力によって被曳航船の船首が特に下がり易いため、曳航時に被曳航船の姿勢が特に崩れ易いおそれがある。 In particular, personal watercraft are generally configured so that the bow of the towed vessel is easily lowered. Therefore, when the towed vessel is a personal watercraft, in the towing method of the first comparative example, the bow of the towed vessel is particularly liable to be lowered by the towing force, so that the attitude of the towed vessel may be particularly liable to collapse during towing.

図１０Ａ〜図１０Ｃは、第２比較例の曳航方法の説明図である。第２比較例の曳航方法は、船舶（ここでも水上オートバイ）のハンドルに曳航ロープ（曳航索）を掛けて、船舶を曳航するものである。第１比較例の曳航方法の場合、作業者が水中でバウアイに曳航ロープを掛ける作業が必要になるため、第２比較例のように、曳航ロープをハンドルに掛けることがある。 10A to 10C are explanatory views of the towing method of the second comparative example. The towing method of the second comparative example is to hang a towing rope (towing rope) on the handle of a ship (also a personal watercraft) to tow the ship. In the case of the towing method of the first comparative example, since the worker needs to hang the towing rope on the bow eye underwater, the towing rope may be hung on the handle as in the second comparative example.

第２比較例では、図１０Ａに示すように、前方向に向かう力と下方向に向かう力（曳航ロープの自重）との合力がハンドルにかかるため、被曳航船にピッチ軸回りのモーメント力がかかることによって、被曳航船の船首を下げる方向に被曳航船に力がかかり、被曳航船の姿勢が崩れるおそれがある。更に、図１０Ａに示すように、ハンドルは、一般的に被曳航船の重心よりも高い位置にあるため、ハンドルに曳航力がかかると、被曳航船にピッチ軸回りのモーメント力がかかることによって、被曳航船の船首を下げる方向に被曳航船に力がかかり易い。 In the second comparative example, as shown in FIG. 10A, since the resultant force of the forward force and the downward force (the own weight of the towing rope) is applied to the handle, the moment force around the pitch axis is applied to the towed vessel. As a result, a force is applied to the towed vessel in the direction of lowering the bow of the towed vessel, which may cause the towed vessel to lose its posture. Further, as shown in FIG. 10A, since the handle is generally located at a position higher than the center of gravity of the towed vessel, when a towing force is applied to the handle, a moment force around the pitch axis is applied to the towed vessel. , The force is likely to be applied to the towed vessel in the direction of lowering the bow of the towed vessel.

また、図１０Ｂに示すように、曳航時に曳航船（不図示）が針路を変更することがある。この結果、被曳航船には、ピッチ軸回りのモーメント力だけでなく、ロール軸回りのモーメント力も加わり、被曳航船の姿勢が崩れ易くなる。特に、図１０Ｃに示すように、ハンドルが被曳航船のメタセンターから見て重心の反対側に位置する場合、例えば図中のハンドルに左方向に向かう力がかかると、船体の傾きを復元させる力（船体の重量によるメタセンター回りのモーメント力）とは反対方向のモーメント力が船体にかかるため、被曳航船のロール軸方向の姿勢が特に不安定になり易くなる。 Further, as shown in FIG. 10B, the towing vessel (not shown) may change course during towing. As a result, not only the moment force around the pitch axis but also the moment force around the roll axis is applied to the towed vessel, and the attitude of the towed vessel is likely to collapse. In particular, as shown in FIG. 10C, when the handle is located on the opposite side of the center of gravity when viewed from the metacenter of the towed ship, for example, when a force toward the left is applied to the handle in the figure, the inclination of the hull is restored. Since a moment force in the direction opposite to the force (moment force around the metacenter due to the weight of the hull) is applied to the hull, the attitude of the towed vessel in the roll axis direction tends to be particularly unstable.

上記の第１比較例及び第２比較例の曳航方法と比べて、次述する本実施形態によれば、被曳航船の姿勢を安定させることが可能である。以下、本実施形態について説明する。 Compared with the towing methods of the first comparative example and the second comparative example described above, according to the present embodiment described below, it is possible to stabilize the attitude of the towed vessel. Hereinafter, this embodiment will be described.

＜曳航器材＞
図１Ａ及び図１Ｂは、本実施形態の曳航器材１の使用時の様子の説明図である。 === This embodiment ===
<Towing equipment>
1A and 1B are explanatory views of a state when the towing equipment 1 of the present embodiment is used.

以下の説明では、図１Ａ及び図１Ｂに示すように、被曳航船の前後方向に沿って、「前」及び「後」を定める。同様に、図１Ａ及び図１Ｂに示すように、被曳航船の左右の方向に沿って、「左」及び「右」を定める。また、前後方向及び左右方向に垂直な方向を「上下方向」とし、被曳航船の船底の側を「下」とし、逆側を「上」とする。なお、船舶のロール軸方向は前後方向であり、ピッチ軸方向は左右方向であり、ヨー軸方向は上下方向である。 In the following description, as shown in FIGS. 1A and 1B, "front" and "rear" are defined along the front-rear direction of the towed vessel. Similarly, as shown in FIGS. 1A and 1B, "left" and "right" are defined along the left and right directions of the towed vessel. Further, the direction perpendicular to the front-rear direction and the left-right direction is defined as "vertical direction", the bottom side of the towed vessel is defined as "downward", and the opposite side is defined as "upper". The roll axis direction of the ship is the front-rear direction, the pitch axis direction is the left-right direction, and the yaw axis direction is the up-down direction.

曳航器材１は、小型の船舶の曳航に用いられる器材である。図中には、小型の船舶の一例として、水上オートバイ（特殊小型船舶）が描かれている。本実施形態の曳航器材１は、特に水上オートバイを曳航する場合に好適に用いることができる。なお、本実施形態の曳航器材１は、被曳航船が水上オートバイに限られるものではなく、例えばモーターボートやミニボート（長さ３ｍ未満のボート）などの他の種類の小型の船舶の曳航にも用いることが可能である。 The towing equipment 1 is equipment used for towing a small ship. In the figure, a personal watercraft (special small vessel) is drawn as an example of a small vessel. The towing equipment 1 of the present embodiment can be suitably used particularly when towing a personal watercraft. The towing equipment 1 of the present embodiment is not limited to the personal watercraft to be towed, but is also used for towing other types of small vessels such as motor boats and mini boats (boats having a length of less than 3 m). It is possible.

曳航器材１は、曳航部材１０と、ベルト５０とを備えている。 The towing equipment 1 includes a towing member 10 and a belt 50.

図２は、曳航部材１０の説明図である。
曳航部材１０は、被曳航船を曳航するための部材である。曳航部材１０は、一対の曳航ロープ２０と、船尾用部材３０とを有する。 FIG. 2 is an explanatory view of the towing member 10.
The towing member 10 is a member for towing a towed vessel. The towing member 10 has a pair of towing ropes 20 and a stern member 30.

曳航ロープ２０は、被曳航船を曳航するためのロープである。曳航ロープ２０は、曳航索や引き綱などと呼ばれることもある。曳航船が曳航ロープ２０を引っ張ることによって、被曳航船を曳航することになる。曳航ロープ２０は、被曳航船の前後方向の長さよりも長いロープである。曳航ロープ２０の基端には、船尾用部材３０が配置されている。曳航ロープ２０の先端には、接続部２１を構成する接続端部２１Ａ（アイ）が設けられている。つまり、曳航ロープ２０の一端（基端）は船尾用部材３０に固定されており、他端には接続部２１が設けられている。 The towing rope 20 is a rope for towing a towed ship. The towing rope 20 is sometimes called a towing rope, a tow rope, or the like. By pulling the towing rope 20 by the towing vessel, the towed vessel will be towed. The towing rope 20 is a rope longer than the length of the towed ship in the front-rear direction. A stern member 30 is arranged at the base end of the towing rope 20. At the tip of the towing rope 20, a connecting end portion 21A (eye) constituting the connecting portion 21 is provided. That is, one end (base end) of the towing rope 20 is fixed to the stern member 30, and the connecting portion 21 is provided at the other end.

一対の曳航ロープ２０が曳航部材１０に設けられている。一対の曳航ロープ２０は、船尾用部材３０の左右の縁からそれぞれ延び出ている。図１Ａ及び図１Ｂに示すように、一対の曳航ロープ２０は、被曳航船の左右の舷側（右舷及び左舷）のそれぞれに前後方向に沿って配置されることになる。このため、曳航ロープ２０は、少なくとも被曳航船よりも長いことが望ましい。 A pair of towing ropes 20 are provided on the towing member 10. The pair of towing ropes 20 extend from the left and right edges of the stern member 30, respectively. As shown in FIGS. 1A and 1B, the pair of towing ropes 20 are arranged along the front-rear direction on each of the left and right side (starboard and port) of the towed vessel. Therefore, it is desirable that the towing rope 20 is at least longer than the towed vessel.

本実施形態では、一本のロープの中央部に船尾用部材３０を取り付けることによって、一本のロープで一対の曳航ロープ２０を構成し、一対のロープ２０のそれぞれを船尾用部材３０の左右の縁から延出させている。但し、一対の曳航ロープ２０をそれぞれ別々のロープで構成し、それぞれのロープの端部を船尾用部材３０の左右の縁に別々に固定しても良い。 In the present embodiment, by attaching the stern member 30 to the central portion of one rope, a pair of towing ropes 20 is formed by one rope, and each of the pair of ropes 20 is left and right of the stern member 30. It extends from the edge. However, the pair of towing ropes 20 may be formed of separate ropes, and the ends of the ropes may be separately fixed to the left and right edges of the stern member 30.

接続部２１は、曳航ロープ２０の端部を他の部材に接続するための部位である。接続部２１は、曳航ロープ２０の端部に設けられている。一対の接続部２１は、曳航時に被曳航船の前側で連結されることになる。ここでは、接続部２１は、接続端部２１Ａと、接続部材２１Ｂとを有する。
接続端部２１Ａは、接続部材２１Ｂを取り付けるための部位である。ここでは、接続端部２１Ａは、曳航ロープ２０の端部に設けられたアイ（輪っか）である。但し、接続端部２１Ａは、接続部材２１Ｂを取り付けることができれば、アイに限られるものではない。
接続部材２１Ｂは、曳航ロープ２０の端部を他の部材に接続するための部材（部品）である。ここでは、接続部材２１Ｂは、開閉可能な金属リングで構成されており、具体的にはカラビナである。但し、接続部材２１Ｂは、曳航ロープ２０の端部を他の部材に接続できれば、カラビナに限られるものではない。
なお、接続部２１は、接続端部２１Ａ（アイ）及び接続部材２１Ｂ（カラビナ）で構成されたものに限られない。例えば、接続部２１を接続端部２１Ａ（アイ）のみで構成することによって、接続部２１が接続部材２１Ｂを有していなくても良い。但し、接続部２１が接続部材２１Ｂを有することによって、後述するように、曳航ロープ２０の端部を器材携行バッグ７０に接続することが可能になる。
また、曳航ロープ２０の端部に接続部２１が無くても良い。但し、曳航ロープ２０の端部に接続部２１を設けることによって、曳航時に曳航ロープ２０を結び付けるなどのロープワークが不要になるため、被曳航船への曳航器材１の取り付けが容易になる。このため、接続部２１が曳航ロープ２０の端部に設けられることが望ましい。 The connecting portion 21 is a portion for connecting the end portion of the towing rope 20 to another member. The connecting portion 21 is provided at the end of the towing rope 20. The pair of connecting portions 21 will be connected on the front side of the towed vessel at the time of towing. Here, the connecting portion 21 has a connecting end portion 21A and a connecting member 21B.
The connection end portion 21A is a portion for attaching the connection member 21B. Here, the connecting end 21A is an eye (ring) provided at the end of the towing rope 20. However, the connection end portion 21A is not limited to the eye as long as the connection member 21B can be attached.
The connecting member 21B is a member (part) for connecting the end of the towing rope 20 to another member. Here, the connecting member 21B is composed of a metal ring that can be opened and closed, and is specifically a carabiner. However, the connecting member 21B is not limited to the carabiner as long as the end portion of the towing rope 20 can be connected to another member.
The connecting portion 21 is not limited to the one composed of the connecting end portion 21A (eye) and the connecting member 21B (carabiner). For example, by configuring the connecting portion 21 with only the connecting end portion 21A (eye), the connecting portion 21 does not have to have the connecting member 21B. However, since the connecting portion 21 has the connecting member 21B, the end portion of the towing rope 20 can be connected to the equipment carrying bag 70, as will be described later.
Further, the connecting portion 21 may not be provided at the end of the towing rope 20. However, by providing the connecting portion 21 at the end of the towing rope 20, rope work such as connecting the towing rope 20 at the time of towing becomes unnecessary, so that the towing equipment 1 can be easily attached to the towed ship. Therefore, it is desirable that the connecting portion 21 is provided at the end of the towing rope 20.

本実施形態では、図１Ａに示すように、一対の接続部２１が連結部材２３によって連結されることになる。連結部材２３は、一対の接続部２１を連結する部材である。また、連結部材２３は、一対の曳航ロープ２０の端部同士を連結するとともに、一対の曳航ロープ２０の端部と曳航船側の部材（例えば曳航船側の曳航ロープ）とを連結するための部材である。連結部材２３の被曳航船側の端部は、一対の接続部２１（接続部材２１Ｂ）を連結する。連結部材２３の曳航船側（被曳航船側とは反対側）の端部は、開閉可能な連結部を有しており、曳航船側の部材（例えば曳航船側の曳航ロープ２０の端部）と連結可能である。ここでは、連結部材２３は、回転部を有する部材で構成されており、具体的にはスイベルである。連結部材２３が回転部を有することによって、連結部材２３の両端が互いに回転可能になり、曳航ロープのねじれを抑制できる。但し、連結部材２３は、一対の接続部２１を連結できれば、スイベルに限られるものではなく、例えば回転部の無いカラビナであっても良い。また、曳航部材１０が連結部材２３を備えなくても良い。例えば、一対の接続部材２１Ｂ（カラビナ）及び連結部材２３（スイベル）を１個のカラビナで代替しても良い。 In the present embodiment, as shown in FIG. 1A, the pair of connecting portions 21 are connected by the connecting member 23. The connecting member 23 is a member that connects the pair of connecting portions 21.

The end of the connecting member 23 on the towed ship side (opposite to the towed ship side) has a connecting portion that can be opened and closed, and can be connected to a member on the towing ship side (for example, the end of the towing rope 20 on the towing ship side). Is. Here, the connecting member 23 is composed of a member having a rotating portion, and is specifically a swivel. Since the connecting member 23 has a rotating portion, both ends of the connecting member 23 can rotate with each other, and twisting of the tow rope can be suppressed. However, the connecting member 23 is not limited to the swivel as long as the pair of connecting portions 21 can be connected, and may be, for example, a carabiner without a rotating portion. Further, the towing member 10 does not have to include the connecting member 23. For example, the pair of connecting members 21B (carabiner) and connecting member 23 (swivel) may be replaced with one carabiner.

船尾用部材３０は、被曳航船の船尾に取り付けられる部材である。船尾用部材３０は、一対の曳航ロープ２０の間に設けられた部材である。船尾用部材３０の左右の縁からそれぞれ曳航ロープ２０が延び出ており、船尾用部材３０を被曳航船の船尾に取り付けることによって、被曳航船の船尾に曳航力を付与することができる。ここでは、船尾用部材３０は、ネット（網状の部材）で構成されている。船尾用部材３０をネットで構成することによって、被曳航船の船尾を覆うように船尾用部材３０を被曳航船に取り付けることができ、曳航時に被曳航船の船尾が損傷することを抑制できる。また、船尾用部材３０をネットで構成することによって、水が網目を通過できるため、曳航時に船尾用部材３０にかかる水流による負荷を軽減できる。但し、船尾用部材３０を網状の部材（ネット）以外の部材で構成しても良い。 The stern member 30 is a member attached to the stern of the towed ship. The stern member 30 is a member provided between the pair of towing ropes 20. Towing ropes 20 extend from the left and right edges of the stern member 30, and by attaching the stern member 30 to the stern of the towed ship, towing force can be applied to the stern of the towed ship. Here, the stern member 30 is composed of a net (net-like member). By forming the stern member 30 with a net, the stern member 30 can be attached to the towed ship so as to cover the stern of the towed ship, and damage to the stern of the towed ship during towing can be suppressed. Further, by forming the stern member 30 with a net, water can pass through the mesh, so that the load due to the water flow applied to the stern member 30 at the time of towing can be reduced. However, the stern member 30 may be composed of a member other than the net-like member (net).

船尾用部材３０は、固定部３１と、錘部３３と、結索部３５とを有する。 The stern member 30 has a fixing portion 31, a weight portion 33, and a tying portion 35.

For example, the mesh of the stern member 30 (net) may be the upper connecting portion 31A.
The fixing member 31B is a member (part) for fixing the stern member 30 to the towed ship. Here, the fixing member 31B is composed of a metal ring that can be opened and closed, and is specifically a carabiner. However, the fixing member 31B is not limited to the carabiner as long as the stern member 30 can be fixed to the towed ship.
The stern member 30 may not have the fixing portion 31. However, by providing the fixing portion 31 on the stern member 30 and fixing the stern member 30 to the towed ship by the fixing portion 31, it is possible to suppress the positional deviation of the towing member 10 with respect to the towed ship in the left-right direction. Therefore, it is desirable that the fixing portion 31 is provided on the stern member 30. By fixing the stern member 30 to the towed ship by the fixing portion 31, there is also an advantage that the stern member 30 can be prevented from being submerged when the stern member 30 is set on the towed ship. ..

錘部３３は、船尾用部材３０の下部を水中に沈めるための部位である。ここでは、錘部３３は、下側接続部３３Ａと、錘部材３３Ｂとを有する。

錘部材３３Ｂは、船尾用部材３０を水中に沈めるための錘（おもり）となる部材である。ここでは、錘部材３３Ｂは、金属リングで構成されており、具体的にはシャックルである。但し、錘部材３３Ｂは、船尾用部材３０を水中に沈めることが可能な部材であれば、シャックルに限られるものではない。
なお、船尾用部材３０に錘部３３が無くても良い。但し、船尾用部材３０が錘部３３を有することにより、船尾用部材３０の下部を水中に沈め易くなり、船尾用部材３０を被曳航船の船尾に取り付ける作業が容易になる。このため、錘部３３が船尾用部材３０に設けられることが望ましい。加えて、錘部材３３Ｂが被曳航船の船尾に配置されると、錘部材３３Ｂが被曳航船の重心よりも後側に配置されるため、曳航時に被曳航船の船首が下がりにくくなり、被曳航船の姿勢を安定化させ易くなるという利点もある。このため、被曳航船が水上オートバイの場合には、錘部３３が船尾用部材３０に設けられることが特に望ましい。 The weight portion 33 is a portion for submerging the lower portion of the stern member 30 into water. Here, the weight portion 33 has a lower connecting portion 33A and a weight member 33B.
The lower connecting portion 33A is a portion for attaching the weight member 33B. The lower connecting portion 33A is a loop-shaped portion provided on the lower side of the stern member 30 (net). However, the lower connecting portion 33A is not limited to the portion configured in a loop shape as long as the weight member 33B can be attached. For example, the mesh of the stern member 30 (net) may be the lower connecting portion 33A.
The weight member 33B is a member that serves as a weight for submerging the stern member 30 in water. Here, the weight member 33B is composed of a metal ring, specifically a shackle. However, the weight member 33B is not limited to a shackle as long as the stern member 30 can be submerged in water.
The stern member 30 may not have the weight portion 33. However, since the stern member 30 has the weight portion 33, the lower portion of the stern member 30 can be easily submerged in water, and the work of attaching the stern member 30 to the stern of the towed ship becomes easy. Therefore, it is desirable that the weight portion 33 is provided on the stern member 30. In addition, when the weight member 33B is arranged at the stern of the towed ship, the weight member 33B is arranged behind the center of gravity of the towed ship, so that the bow of the towed ship is difficult to lower during towing, and the towed ship is covered. It also has the advantage of making it easier to stabilize the attitude of the towed vessel. Therefore, when the towed ship is a personal watercraft, it is particularly desirable that the weight portion 33 is provided on the stern member 30.

結索部３５は、船尾用部材３０の縁を結び付けるための部位である。図１Ａ及び図１Ｂに示すように、結索部３５が船尾用部材３０の左右それぞれの上縁と下縁とを結び付けることによって、船尾用部材３０が袋状になり、船尾用部材３０が船尾から外れにくくなる。但し、船尾用部材３０に結索部３５が無くても良い。

If so, the lower edge of the stern member 30 is pulled toward the upper edge by pulling the towing rope 20, so that the work of inserting the towing rope 20 into the tying portion 35 (carabiner) becomes easy.

図３Ａ〜図３Ｃは、ベルト５０の説明図である。図３Ａは、ベルト５０の側面図である。図３Ｂは、ベルト５０の底面図である。図３Ｃは、ベルト５０の使用時の説明図である。なお、図３Ａ及び図３Ｂでは、ベルト用錘部材５４Ｂを外した状態でベルト５０の本体が示されている。 3A to 3C are explanatory views of the belt 50. FIG. 3A is a side view of the belt 50. FIG. 3B is a bottom view of the belt 50. FIG. 3C is an explanatory diagram when the belt 50 is used. In addition, in FIG. 3A and FIG. 3B, the main body of the belt 50 is shown with the weight member 54B for the belt removed.

ベルト５０は、被曳航船の船体に巻き付けるための帯状の部材である。図１Ａ及び図１Ｂに示すように、ベルト５０は、被曳航船の船底に架け渡されて、上下方向に巻き付けられることになる。ベルト５０は、被曳航船に対して曳航ロープ２０を所定位置に配置するための部材である。ベルト５０に曳航ロープ２０を挿通させることによって、被曳航船に対する曳航ロープ２０の位置が安定する。具体的には、図１Ａに示すように、ベルト５０に曳航ロープ２０を挿通させることによって、被曳航船の舷側に沿って曳航ロープ２０を配置できる。なお、ベルト５０には曳航ロープ２０を挿通させるだけなので、曳航力は、ベルト５０には付与されず、曳航ロープ２０を介して被曳航船の船尾に付与されることになる。 The belt 50 is a band-shaped member for winding around the hull of the towed ship. As shown in FIGS. 1A and 1B, the belt 50 is hung on the bottom of the towed ship and wound in the vertical direction. The belt 50 is a member for arranging the towing rope 20 at a predetermined position with respect to the towed ship. By inserting the towing rope 20 through the belt 50, the position of the towing rope 20 with respect to the towed ship is stabilized. Specifically, as shown in FIG. 1A, the towing rope 20 can be arranged along the side of the towed ship by inserting the towing rope 20 through the belt 50. Since the towing rope 20 is only inserted into the belt 50, the towing force is not applied to the belt 50 but is applied to the stern of the towed ship via the towing rope 20.

ベルト５０は、結合部５１と、挿通部５２と、ベルト用錘部５４とを有する。 The belt 50 has a connecting portion 51, an insertion portion 52, and a belt weight portion 54.

結合部５１は、ベルト５０の本体の両端同士を着脱可能に結合する部位である。結合部５１によってベルト５０の両端を結合することによって、ベルト５０を被曳航船に巻き付けた状態でベルト５０を被曳航船に固定できる。結合部５１は、被曳航船の船体の大きさに応じて調整可能に構成されていることが望ましい。ここでは、結合部５１は、面ファスナーで構成されている。但し、結合部５１は、ベルト５０の本体の両端を結合できれば、面ファスナーに限られるものではなく、たとえばバックルなどの部材で構成されても良い。 The connecting portion 51 is a portion that detachably connects both ends of the main body of the belt 50.

It is desirable that the joint portion 51 is configured to be adjustable according to the size of the hull of the towed ship. Here, the joint portion 51 is composed of a hook-and-loop fastener. However, the connecting portion 51 is not limited to the hook-and-loop fastener as long as both ends of the main body of the belt 50 can be connected, and may be composed of a member such as a buckle.

挿通部５２は、曳航ロープ２０を挿通させる部位である。ここでは、挿通部５２は、輪っかで構成されている。但し、挿通部５２は、曳航ロープ２０を挿通可能であれば、輪っかに限られるものではなく、例えば、ベルト５０に形成された穴でも良い。挿通部５２は曳航ロープ２０の直径よりも大きな輪っかで構成されている。このため、挿通部５２と曳航ロープ２０との間に隙間が形成されており、挿通部５２に対して曳航ロープ２０の周囲に遊びがある（挿通部５２に対して曳航ロープ２０の若干の移動が許容されている）。挿通部５２に曳航ロープ２０を挿通させることによって、ベルト５０に曳航力を付与させることなく、曳航ロープ２０を被曳航船の舷側に配置できる。挿通部５２は、ベルト５０を被曳航船に巻き付けたときに、被曳航船の右舷及び左舷のそれぞれに配置されるように、ベルト５０に設けられている。このため、挿通部５２は、ベルト５０の中央部（ベルト用錘部５４）とベルト５０の端部（結合部５１）との間に設けられている。 The insertion portion 52 is a portion through which the towing rope 20 is inserted. Here, the insertion portion 52 is composed of a ring. However, the insertion portion 52 is not limited to the ring as long as the towing rope 20 can be inserted, and may be, for example, a hole formed in the belt 50. The insertion portion 52 is composed of a ring larger than the diameter of the towing rope 20. Therefore, a gap is formed between the insertion portion 52 and the towing rope 20, and there is play around the towing rope 20 with respect to the insertion portion 52 (slight movement of the towing rope 20 with respect to the insertion portion 52). Is allowed). By inserting the towing rope 20 through the insertion portion 52, the towing rope 20 can be arranged on the side of the towed ship without applying the towing force to the belt 50. The insertion portion 52 is provided on the belt 50 so that when the belt 50 is wound around the towed ship, it is arranged on the starboard side and the port side of the towed ship, respectively. Therefore, the insertion portion 52 is provided between the central portion of the belt 50 (belt weight portion 54) and the end portion of the belt 50 (joining portion 51).

ベルト５０は、少なくとも２つの挿通部５２（少なくとも一対の挿通部５２；一対のデイジーチェーン５３）を有しており、ベルト５０を被曳航船に巻き付けたときに、被曳航船の右舷及び左舷のそれぞれに少なくとも１つの挿通部５２が配置される。つまり、少なくとも１つの挿通部５２が、ベルト５０の一端（図３Ａの左端）とベルト５０の中央部（錘接続部５４Ａ）との間に設けられており、少なくとも１つの別の挿通部５２が、ベルト５０の他端（図３Ａの右端）とベルト５０の中央部（錘接続部５４Ａ）との間に設けられている。 The belt 50 has at least two insertion portions 52 (at least a pair of insertion portions 52; a pair of daisy chains 53), and when the belt 50 is wound around the towed vessel, the starboard and port sides of the towed vessel At least one insertion portion 52 is arranged in each.

By arranging a plurality of insertion portions 52 on the starboard side and the port side side by side in the vertical direction, the towing rope 20 can be inserted into the insertion portions 52 at appropriate positions according to the size of the hull of the towed ship. The towing rope 20 can be placed at an appropriate position for towed vessels of various sizes. Here, a pair of daisy chains 53 are provided in the main body of the belt 50, and a plurality of continuous insertion portions 52 (insertion portions group) are configured by each daisy chain 53. However, the plurality of continuous insertion portions 52 (insertion portions group) are not limited to those configured by the daisy chain 53.

ベルト用錘部５４は、ベルト５０の下部を水中に沈めるための部位である。ここでは、ベルト用錘部５４は、錘接続部５４Ａと、ベルト用錘部材５４Ｂとを有する。
錘接続部５４Ａは、ベルト用錘部材５４Ｂを接続するための部位である。錘接続部５４Ａは、ベルト５０の中央部に設けられたループ状の部位である。但し、錘接続部５４Ａは、ベルト用錘部材５４Ｂを接続することができれば、ループ状の形状に限られるものではない。また、ベルト５０に錘接続部５４Ａが無くても良い。この場合、ベルト５０を環状のベルト用錘部材５４Ｂ（カラビナ）に挿通させるだけでも良い。但し、錘接続部５４Ａにベルト用錘部材５４Ｂを取り付けることによって、ベルト用錘部材５４Ｂの位置が安定する。このため、ベルト５０が錘接続部５４Ａを有することが望ましい。
ベルト用錘部材５４Ｂは、ベルト５０を水中に沈めるための錘（おもり）となる部材である。ここでは、ベルト用錘部材５４Ｂは、金属リングで構成されており、具体的にはカラビナである。但し、ベルト用錘部材５４Ｂは、ベルト５０を水中に沈めることが可能な部材であれば、カラビナに限られるものではない。
なお、ベルト５０にベルト用錘部５４が無くても良い。但し、ベルト５０がベルト用錘部５４を有することにより、ベルト５０の中央部を水中に沈め易くなり、ベルト５０を被曳航船に巻き付ける作業が容易になる。このため、ベルト５０がベルト用錘部５４を有することが望ましい。 The belt weight portion 54 is a portion for submerging the lower portion of the belt 50 into water. Here, the belt weight portion 54 has a weight connecting portion 54A and a belt weight member 54B.
The weight connecting portion 54A is a portion for connecting the weight member 54B for the belt. The weight connecting portion 54A is a loop-shaped portion provided in the central portion of the belt 50. However, the weight connecting portion 54A is not limited to the loop shape as long as the belt weight member 54B can be connected. Further, the belt 50 may not have the weight connecting portion 54A. In this case, the belt 50 may be simply inserted through the annular belt weight member 54B (carabiner). However, by attaching the belt weight member 54B to the weight connecting portion 54A, the position of the belt weight member 54B is stabilized. Therefore, it is desirable that the belt 50 has the weight connecting portion 54A.
The belt weight member 54B is a member that serves as a weight for submerging the belt 50 in water. Here, the weight member 54B for the belt is made of a metal ring, and is specifically a carabiner. However, the weight member 54B for the belt is not limited to the carabiner as long as it is a member capable of submerging the belt 50 in water.
The belt 50 may not have the weight portion 54 for the belt. However, since the belt 50 has the weight portion 54 for the belt, the central portion of the belt 50 can be easily submerged in water, and the work of winding the belt 50 around the towed ship becomes easy. Therefore, it is desirable that the belt 50 has a weight portion 54 for the belt.

ベルト５０は、被曳航船の重心よりも前側の位置で被曳航船に巻き付けられることになる。被曳航船が水上オートバイの場合、図１Ａ及び図１Ｂに示すように、ベルト５０は、ハンドルとフードとの間の凹部で、被曳航船に巻き付けられる。ハンドルは、被曳航船の重心よりも前側にあるため、ハンドルとフードとの間の凹部でベルト５０が被曳航船に巻き付けられると、ベルト５０は、被曳航船の重心よりも前側に配置される。また、ベルト５０を被曳航船に巻き付けると、ベルト５０の挿通部５２（複数の挿通部５２のうちの少なくとも１つの挿通部５２）は、ハンドルよりも下側に配置される。また、ベルト５０を被曳航船に巻き付けると、ベルト５０の挿通部５２（複数の挿通部５２のうちの少なくとも１つの挿通部５２）は、メタセンター（図１０Ｃ参照）よりも下側に配置される。 The belt 50 will be wound around the towed vessel at a position in front of the center of gravity of the towed vessel. When the towed vessel is a personal watercraft, the belt 50 is wrapped around the towed vessel at the recess between the handle and the hood, as shown in FIGS. 1A and 1B. Since the handle is in front of the center of gravity of the towed vessel, when the belt 50 is wrapped around the towed vessel in the recess between the handle and the hood, the belt 50 is placed in front of the center of gravity of the towed vessel. NS. Further, when the belt 50 is wound around the towed ship, the insertion portion 52 of the belt 50 (at least one insertion portion 52 of the plurality of insertion portions 52) is arranged below the handle. Further, when the belt 50 is wound around the towed vessel, the insertion portion 52 of the belt 50 (at least one insertion portion 52 of the plurality of insertion portions 52) is arranged below the metacenter (see FIG. 10C). NS.

図１Ａ及び図１Ｂに示すように、船尾に取り付けられた船尾用部材３０から延び出た一対の曳航ロープ２０は、舷側に配置されたベルト５０の挿通部５２にそれぞれ挿通された状態である。この状態では、曳航ロープ２０の自重はベルト５０にかかるが、第１比較例（図９Ａ及び図９Ｂ参照）に示すバウアイと重心との距離に比べるとベルト５０と重心との距離が短い。このため、本実施形態では、第１比較例と比べると、被曳航船にかかるピッチ軸回りのモーメント力を軽減することができるため、被曳航船の船首を下げる方向には被曳航船に力がかかり難くなる。この結果、本実施形態では、第１比較例と比べて、曳航時の被曳航船の姿勢を安定させることができる。 As shown in FIGS. 1A and 1B, the pair of towing ropes 20 extending from the stern member 30 attached to the stern are in a state of being inserted into the insertion portion 52 of the belt 50 arranged on the side. In this state, the weight of the towing rope 20 is applied to the belt 50, but the distance between the belt 50 and the center of gravity is shorter than the distance between the bow eye and the center of gravity shown in the first comparative example (see FIGS. 9A and 9B). Therefore, in the present embodiment, as compared with the first comparative example, the moment force around the pitch axis applied to the towed ship can be reduced, so that the force is applied to the towed ship in the direction of lowering the bow of the towed ship. It becomes difficult to apply. As a result, in the present embodiment, the attitude of the towed vessel at the time of towing can be stabilized as compared with the first comparative example.

また、図１Ｂに示すように、曳航ロープ２０は、ベルト５０の挿通部５２に挿通させることによって、被曳航船の船尾から前側に向かって舷側に沿って配置される。これにより、本実施形態では、曳航ロープ２０の上下方向の位置と、被曳航船の重心の上下方向の位置との差を小さくすることができる。このため、本実施形態では、第２比較例（図１０Ａ参照）と比べると、曳航時に被曳航船にかかるピッチ軸回りのモーメント力を軽減することができるため、被曳航船の船首を下げる方向には被曳航船に力がかかり難くなる。この結果、本実施形態では、第２比較例と比べても、曳航時の被曳航船の姿勢を安定させることができる。 Further, as shown in FIG. 1B, the towing rope 20 is arranged along the side from the stern of the towed ship toward the front side by inserting it into the insertion portion 52 of the belt 50. Thereby, in the present embodiment, the difference between the vertical position of the towing rope 20 and the vertical position of the center of gravity of the towed ship can be reduced. Therefore, in the present embodiment, as compared with the second comparative example (see FIG. 10A), the moment force around the pitch axis applied to the towed vessel during towing can be reduced, so that the bow of the towed vessel is lowered. It becomes difficult for the towed ship to be stressed. As a result, in the present embodiment, the attitude of the towed vessel at the time of towing can be stabilized as compared with the second comparative example.

加えて、本実施形態では、曳航ロープ２０の上下方向の位置と、被曳航船の重心の上下方向の位置との差が小さいため、第２比較例（図１０Ｃ参照）と比べると、曳航船が針路を変更したときに被曳航船にかかるロール軸回りのモーメント力を軽減することができる。言い換えると、本実施形態では、ハンドルよりも下側に配置された挿通部５２に曳航ロープ２０を挿通することによって、第２比較例（図１０Ｃ参照）と比べると、曳航船が針路を変更したときに被曳航船にかかるロール軸回りのモーメント力を軽減することができる。特に、本実施形態では、メタセンター（図１０Ｃ参照）よりも下側に配置された挿通部５２に曳航ロープ２０を挿通することによって、船体の傾きを復元させる力（船体の重量によるメタセンター回りのモーメント力）とは反対方向のモーメント力が船体にかかることを抑制できる。この結果、本実施形態によれば、曳航船が針路を変更しても、被曳航船の姿勢を安定させることができる。 In addition, in the present embodiment, the difference between the vertical position of the towed rope 20 and the vertical position of the center of gravity of the towed ship is small, so that the towed ship is compared with the second comparative example (see FIG. 10C). It is possible to reduce the moment force around the roll axis applied to the towed vessel when the course is changed. In other words, in the present embodiment, by inserting the towing rope 20 into the insertion portion 52 arranged below the handle, the towing vessel changes the course as compared with the second comparative example (see FIG. 10C). Sometimes it is possible to reduce the moment force around the roll axis applied to the towed vessel. In particular, in the present embodiment, a force for restoring the inclination of the hull (around the metacenter due to the weight of the hull) by inserting the towing rope 20 into the insertion portion 52 arranged below the metacenter (see FIG. 10C). It is possible to prevent the moment force in the direction opposite to the moment force of) from being applied to the hull. As a result, according to the present embodiment, the attitude of the towed vessel can be stabilized even if the towed vessel changes course.

なお、本実施形態では、ベルト５０は被曳航船の重心よりも前側に配置されているとともに、上記の通りピッチ軸方向及びロール軸方向の被曳航船の姿勢が安定しているため、曳航船が針路を変更しても、被曳航船は、ヨー軸方向に安定した状態で針路変更可能である。このため、本実施形態の曳航器材１によれば、被曳航船を安定して曳航可能である。 In the present embodiment, the belt 50 is arranged in front of the center of gravity of the towed vessel, and the attitude of the towed vessel in the pitch axis direction and the roll axis direction is stable as described above. Even if the course is changed, the towed vessel can change course in a stable state in the yaw axis direction. Therefore, according to the towing equipment 1 of the present embodiment, the towed ship can be towed stably.

Further, in order to facilitate the connection of the fixing member 31B to the upper connecting portion 71A, it is desirable that the upper connecting portion 71A is provided in the vicinity of the upper opening 81.

挿通口８２は、器材携行バッグ７０の左右に設けられた開口である。挿通口８２は、本体部７１と開閉部材７２との間に設けられた開口である。器材携行バッグ７０は一対の挿通口８２を備えており、器材携行バッグ７０の左右それぞれに挿通口８２が設けられている。挿通口８２には、本体部７１と開閉部材７２とを接合するファスナー７５が設けられていない。このため、挿通口８２では、本体部７１及び開閉部材７２はファスナー７５によって接合されておらず、非接合部になっている。 The insertion port 82 is an opening provided on the left and right sides of the equipment carrying bag 70. The insertion port 82 is an opening provided between the main body 71 and the opening / closing member 72. The equipment carrying bag 70 is provided with a pair of insertion ports 82, and insertion ports 82 are provided on the left and right sides of the equipment carrying bag 70, respectively. The insertion port 82 is not provided with a fastener 75 for joining the main body 71 and the opening / closing member 72. Therefore, in the insertion port 82, the main body portion 71 and the opening / closing member 72 are not joined by the fastener 75, but are not joined.

図４に示すように、挿通口８２に曳航ロープ２０を挿通させることによって、挿通口８２から曳航ロープ２０の端部（接続部２１）を露出させた状態で、器材携行バッグ７０に曳航部材１０を収容することが可能である。曳航ロープ２０の端部を器材携行バッグ７０の外部に露出させることによって、曳航部材１０の使用時に、器材携行バッグ７０から曳航ロープ２０を取り出す作業が容易になる。 As shown in FIG. 4, by inserting the towing rope 20 into the insertion port 82, the towing member 10 is inserted into the equipment carrying bag 70 in a state where the end portion (connection portion 21) of the towing rope 20 is exposed from the insertion port 82. Can be accommodated. By exposing the end of the towing rope 20 to the outside of the equipment carrying bag 70, it becomes easy to take out the towing rope 20 from the equipment carrying bag 70 when the towing member 10 is used.

また、本実施形態では、曳航ロープ２０の端部に設けられた接続部２１が接続部材２１Ｂ（カラビナ）を有しているため、図４に示すように、接続部材２１Ｂを器材携行バッグ７０の取付部７４に接続することが可能である。接続部材２１Ｂを器材携行バッグ７０の取付部７４に接続することによって、挿通口８２から曳航部材１０の接続部２１を露出させた状態を安定的に保持できる。このため、図４に示すように、器材携行バッグ７０に曳航部材１０を収容した状態では、接続部材２１Ｂを器材携行バッグ７０の取付部７４に接続することが望ましい。また、接続部材２１Ｂを取付部７４に接続し易くするために、取付部７４は挿通口８２の近傍に設けられることが望ましい。 Further, in the present embodiment, since the connecting portion 21 provided at the end of the towing rope 20 has the connecting member 21B (carabiner), as shown in FIG. 4, the connecting member 21B is attached to the equipment carrying bag 70. It can be connected to the mounting portion 74.

The upper end of the lower belt 92 is connected to the lower end of the intermediate belt 93 via the lower fastener 95. The intermediate belt 93 is a band-shaped member forming the central portion of the shoulder belt 90, and is a member arranged between the upper belt 91 and the lower belt 92. The upper end of the intermediate belt 93 is connected to the lower end of the upper belt 91 via the upper fastener 94. The lower end of the intermediate belt 93 is connected to the upper end of the lower belt 92 via the lower fastener 95. Thereby, in the present embodiment, the intermediate belt 93 can be removed from the main body 71 by removing the fasteners (upper fastener 94 and lower fastener 95) at both ends.

中間ベルト９３は、調整部９３Ａを有する。調整部９３Ａは、長さを調整する部位である。調整部９３Ａによって肩ベルト９０の長さを調整可能である。なお、調整部９３Ａが中間ベルト９３に設けられずに上側ベルト９１又は下側ベルト９２に設けられても良いし、肩ベルト９０に調整部９３Ａが無くても良い。但し、中間ベルト９３が調整部９３Ａを有することによって、器材携行バッグ７０から外した中間ベルト９３の長さが調整可能になる。 The intermediate belt 93 has an adjusting unit 93A. The adjusting unit 93A is a portion for adjusting the length. The length of the shoulder belt 90 can be adjusted by the adjusting unit 93A. The adjusting portion 93A may not be provided on the intermediate belt 93 but may be provided on the upper belt 91 or the lower belt 92, or the shoulder belt 90 may not have the adjusting portion 93A. However, since the intermediate belt 93 has the adjusting portion 93A, the length of the intermediate belt 93 removed from the equipment carrying bag 70 can be adjusted.

上側留め具９４は、上側ベルト９１と中間ベルト９３とを連結する部材である。下側留め具９５は、下側ベルト９２と中間ベルト９３とを連結する部材である。上側留め具９４及び下側留め具９５は、例えばバックルで構成されており、それぞれ雄部材と雌部材をそれぞれ有する。上側留め具９４及び下側留め具９５を外すことによって、器材携行バッグ７０（詳しくは本体部７１）から中間ベルト９３を取り出すことが可能である。 The upper fastener 94 is a member that connects the upper belt 91 and the intermediate belt 93. The lower fastener 95 is a member that connects the lower belt 92 and the intermediate belt 93. The upper fastener 94 and the lower fastener 95 are composed of, for example, a buckle, and each has a male member and a female member, respectively. By removing the upper fastener 94 and the lower fastener 95, the intermediate belt 93 can be taken out from the equipment carrying bag 70 (specifically, the main body 71).

本実施形態では、中間ベルト９３の一端に雄部材が設けられており、中間ベルト９３の他端に雌部材が設けられている。これにより、器材携行バッグ７０から中間ベルト９３を外した後に、中間ベルト９３の両端の留め具（雄部材と雌部材）を連結することが可能である。中間ベルト９３の両端の留め具を連結することによって、中間ベルト９３を環状にすることが可能であり、取り外した中間ベルト９３を被曳航船（例えば船外機）に巻き付けて固定することが可能である（後述；図８Ａ参照）。 In the present embodiment, a male member is provided at one end of the intermediate belt 93, and a female member is provided at the other end of the intermediate belt 93. Thereby, after removing the intermediate belt 93 from the equipment carrying bag 70, it is possible to connect the fasteners (male member and female member) at both ends of the intermediate belt 93. By connecting the fasteners at both ends of the intermediate belt 93, the intermediate belt 93 can be made into an annular shape, and the removed intermediate belt 93 can be wound around a towed ship (for example, an outboard motor) and fixed.

＜曳航器材１及び器材携行バッグ７０の使用方法＞
図７Ａ〜図７Ｄは、曳航器材１及び器材携行バッグ７０の使用方法の説明図である。言い換えると、図７Ａ〜図７Ｄは、器材携行バッグ７０に収容された曳航器材１を被曳航船にセットする方法の説明図である。 <How to use towing equipment 1 and equipment carrying bag 70>
7A to 7D are explanatory views of how to use the towing equipment 1 and the equipment carrying bag 70. In other words, FIGS. 7A to 7D are explanatory views of a method of setting the towing equipment 1 housed in the equipment carrying bag 70 on the towed ship.

まず、作業者は、曳航器材１を収容した器材携行バッグ７０を準備する。そして、作業者は、図７Ａに示すように、固定部材３１Ｂ（カラビナ）を被曳航船のスターンアイに固定する。固定部材３１Ｂ（カラビナ）を被曳航船に固定することによって、被曳航船に対する曳航部材１０の左右方向の位置ズレを抑制できる。この結果、曳航部材１０が被曳航船の中央位置に配置されるため（曳航部材１０が被曳航船に対して左右対称に配置されるため）、後述する作業において、左右それぞれの曳航ロープ１０を適切に配置し易くなる。また、固定部材３１Ｂ（カラビナ）を被曳航船に固定することによって、曳航器材１を被曳航船にセットするときに曳航部材１０を水没させてしまうことを防止できるという利点もある。 First, the worker prepares an equipment carrying bag 70 containing the towing equipment 1. Then, as shown in FIG. 7A, the operator fixes the fixing member 31B (carabiner) to the stern eye of the towed vessel. By fixing the fixing member 31B (carabiner) to the towed vessel, it is possible to suppress the positional deviation of the towing member 10 in the left-right direction with respect to the towed vessel. As a result, since the towing member 10 is arranged at the center position of the towed ship (because the towing member 10 is arranged symmetrically with respect to the towed ship), the left and right towing ropes 10 are used in the work described later. It becomes easy to arrange properly. Further, by fixing the fixing member 31B (carabiner) to the towed ship, there is an advantage that the towing member 10 can be prevented from being submerged when the towing equipment 1 is set on the towed ship.

このとき、作業者は、器材携行バッグ７０の本体部７１を被曳航船側（前側）とし、開閉部材７２を外側（後側）に向けて、器材携行バッグ７０を被曳航船に固定する。これにより、開閉部材７２の開閉が容易になる。なお、図４に示すように、器材携行バッグ７０の外側には、曳航部材１０（詳しくは船尾用部材３０）の固定部３１が露出している。このため、作業者が固定部３１を被曳航船に固定する作業は容易である。 At this time, the operator fixes the equipment carrying bag 70 to the towed ship with the main body 71 of the equipment carrying bag 70 facing the towed ship side (front side) and the opening / closing member 72 facing the outside (rear side). This facilitates opening and closing of the opening / closing member 72. As shown in FIG. 4, the fixing portion 31 of the towing member 10 (specifically, the stern member 30) is exposed on the outside of the equipment carrying bag 70. Therefore, it is easy for the operator to fix the fixing portion 31 to the towed vessel.

また、本実施形態では、図４に示すように、器材携行バッグ７０の上側に設けられた上側開口８１から曳航部材１０の固定部３１が露出している。このため、固定部３１を被曳航船に固定すれば、そのまま自然に、被曳航船に器材携行バッグ７０（曳航部材１０を収容した器材携行バッグ７０）を吊り下げることができる。これにより、この後の曳航器材１を被曳航船にセットする作業が容易になる。 Further, in the present embodiment, as shown in FIG. 4, the fixing portion 31 of the towing member 10 is exposed from the upper opening 81 provided on the upper side of the equipment carrying bag 70. Therefore, if the fixing portion 31 is fixed to the towed ship, the equipment carrying bag 70 (equipment carrying bag 70 containing the towing member 10) can be naturally hung from the towed ship as it is. This facilitates the subsequent work of setting the towing equipment 1 on the towed vessel.

なお、作業者は、固定部材３１Ｂ（カラビナ）を被曳航船のスターンアイに固定する際に、固定部材３１Ｂによって器材携行バッグ７０の上側接続部７１Ａもスターンアイに固定することが望ましい。若しくは、作業者は、固定部材３１Ｂ（カラビナ）を被曳航船のスターンアイに固定する際に、船尾用部材３０の上側接続部３１Ａを器材携行バッグ７０の上側接続部７１Ａに挿通させておくことが望ましい。これにより、曳航器材１を被曳航船にセットするときに、器材携行バッグ７０を水没させてしまうことを防止できる。 When the worker fixes the fixing member 31B (carabiner) to the stern eye of the towed ship, it is desirable that the fixing member 31B also fixes the upper connecting portion 71A of the equipment carrying bag 70 to the stern eye. Alternatively, the operator should insert the upper connecting portion 31A of the stern member 30 into the upper connecting portion 71A of the equipment carrying bag 70 when fixing the fixing member 31B (carabiner) to the stern eye of the towed ship. Is desirable. This makes it possible to prevent the equipment carrying bag 70 from being submerged when the towing equipment 1 is set on the towed ship.

固定部材３１Ｂ（カラビナ）を被曳航船のスターンアイに固定した後、図７Ａに示すように、作業者は、器材携行バッグ７０の収容部７３からベルト５０（図３Ａ〜図３Ｃ参照）を取り出す。そして、作業者は、図７Ｂに示すように、被曳航船の船体にベルト５０を巻き付ける。このとき、作業者は、ベルト５０の中央部を船底に架け渡しつつ、結合部５１によってベルト５０の両端を結合することによって、ベルト５０を上下方向に沿って被曳航船に巻き付けた状態で、ベルト５０を被曳航船に固定する。ベルト５０の中央部の錘接続部５４Ａにベルト用錘部材５４Ｂが取り付けられていれば、ベルト５０の中央部を水中に沈め易くなり、ベルト５０の中央部を船底に架け渡す作業が容易になり、この結果、ベルト５０を被曳航船に巻き付ける作業が容易になる。なお、ベルト用錘部材５４Ｂは、錘接続部５４Ａに取り付けられた状態で収容部７３に収容されていても良いし、作業者が、収容部７３から取り出したベルト５０の錘接続部５４Ａに、取付部７４から外したベルト用錘部材５４Ｂ（カラビナ）を取り付けても良い。 After fixing the fixing member 31B (carabiner) to the stern eye of the towed vessel, as shown in FIG. 7A, the operator takes out the belt 50 (see FIGS. 3A to 3C) from the accommodating portion 73 of the equipment carrying bag 70. .. Then, as shown in FIG. 7B, the worker winds the belt 50 around the hull of the towed ship. At this time, the worker wraps the belt 50 around the towed ship in the vertical direction by connecting both ends of the belt 50 with the connecting portion 51 while bridging the central portion of the belt 50 to the bottom of the ship. The belt 50 is fixed to the towed ship. If the weight member 54B for the belt is attached to the weight connecting portion 54A at the center of the belt 50, the central portion of the belt 50 can be easily submerged in water, and the central portion of the belt 50 can be easily bridged to the bottom of the ship. As a result, the work of winding the belt 50 around the towed ship becomes easy. The belt weight member 54B may be housed in the accommodating portion 73 in a state of being attached to the weight connecting portion 54A, or may be accommodated in the weight connecting portion 54A of the belt 50 taken out from the accommodating portion 73 by the operator. The belt weight member 54B (carabiner) removed from the mounting portion 74 may be mounted.

なお、図７Ｂ（及び図１Ｂ）に示すように、作業者は、ハンドルとフードとの間の凹部でベルト５０を被曳航船に巻き付ける。ハンドルは、被曳航船の重心よりも前側にあるため、ハンドルとフードとの間の凹部でベルト５０が被曳航船に巻き付けられると、ベルト５０は、被曳航船の重心よりも前側に配置される。また、ベルト５０が被曳航船に巻き付けられると、ベルト５０の挿通部５２（複数の挿通部５２のうちの少なくとも１つの挿通部５２）は、被曳航船の舷側（右舷及び左舷）に配置される。 As shown in FIG. 7B (and FIG. 1B), the operator winds the belt 50 around the towed vessel in the recess between the handle and the hood. Since the handle is in front of the center of gravity of the towed vessel, when the belt 50 is wrapped around the towed vessel in the recess between the handle and the hood, the belt 50 is placed in front of the center of gravity of the towed vessel. NS. Further, when the belt 50 is wound around the towed ship, the insertion portion 52 of the belt 50 (at least one insertion portion 52 of the plurality of insertion portions 52) is arranged on the side (starboard and port) of the towed ship. NS.

ベルト５０を被曳航船に巻き付けた後、図７Ｃに示すように、作業者は、器材携行バッグ７０から曳航ロープ２０を取り出す。本実施形態では、ファスナー７５によって本体部７１と開閉部材７２とが閉じられた状態で、器材携行バッグ７０の挿通口８２から曳航ロープ２０を引き出すことが可能である。このため、長尺な曳航ロープ２０が絡むことなく、作業者は、器材携行バッグ７０から曳航ロープ２０を取り出すことができる。なお、図４に示すように、器材携行バッグ７０の外部には、曳航ロープ２０の端部（接続部２１）が露出している。このため、作業者は、露出している曳航ロープ２０の端部を引っ張れば、器材携行バッグ７０から曳航ロープ２０を引き出すことができるため、曳航ロープ２０を取り出す作業は容易である。但し、作業者は、器材携行バッグ７０の開閉部材７２を開けてから、曳航ロープ２０を器材携行バッグ７０から取り出しても良い。 After wrapping the belt 50 around the towed vessel, the operator takes out the towing rope 20 from the equipment carrying bag 70 as shown in FIG. 7C. In the present embodiment, the towing rope 20 can be pulled out from the insertion port 82 of the equipment carrying bag 70 in a state where the main body 71 and the opening / closing member 72 are closed by the fastener 75. Therefore, the operator can take out the towing rope 20 from the equipment carrying bag 70 without the long towing rope 20 getting entangled. As shown in FIG. 4, the end portion (connecting portion 21) of the towing rope 20 is exposed to the outside of the equipment carrying bag 70. Therefore, the operator can pull out the towing rope 20 from the equipment carrying bag 70 by pulling the exposed end portion of the towing rope 20, so that the work of taking out the towing rope 20 is easy. However, the operator may take out the towing rope 20 from the equipment carrying bag 70 after opening the opening / closing member 72 of the equipment carrying bag 70.

また、図７Ｃに示すように、作業者は、曳航ロープ２０をベルト５０の挿通部５２に挿通させる。図７Ｃに示すように、ベルト５０の挿通部５２は、被曳航船のハンドル付近の舷側に配置されているため、作業者は、被曳航船に搭乗しながら、曳航ロープ２０をベルト５０の挿通部５２に挿通させることができる。本実施形態では、被曳航船の舷側に複数の挿通部５２が上下方向に並んで配置されているため、作業者は、適切な高さの挿通部５２を選択して、曳航ロープ２０をベルト５０の挿通部５２に挿通させることになる。なお、既に説明した通り、図４に示すように、器材携行バッグ７０の外部には、曳航ロープ２０の端部（接続部２１）が露出している。このため、作業者は、曳航ロープ２０の端部を把持し易いため、ベルト５０の挿通部５２に曳航ロープ２０の端部から挿通させる作業は容易である。作業者は、被曳航船の右舷及び左舷のそれぞれにおいて、曳航ロープ２０をベルト５０の挿通部５２に挿通させることになる。 Further, as shown in FIG. 7C, the operator inserts the towing rope 20 into the insertion portion 52 of the belt 50. As shown in FIG. 7C, since the insertion portion 52 of the belt 50 is arranged on the side near the handle of the towed ship, the operator inserts the towing rope 20 into the belt 50 while boarding the towed ship. It can be inserted through the portion 52. In the present embodiment, since a plurality of insertion portions 52 are arranged side by side in the vertical direction on the side of the towed ship, the operator selects the insertion portions 52 having an appropriate height and belts the tow rope 20. It will be inserted through the insertion portion 52 of 50. As already described, as shown in FIG. 4, the end portion (connecting portion 21) of the towing rope 20 is exposed to the outside of the equipment carrying bag 70. Therefore, since the operator can easily grip the end portion of the towing rope 20, the work of inserting the insertion portion 52 of the belt 50 from the end portion of the towing rope 20 is easy. The operator inserts the towing rope 20 into the insertion portion 52 of the belt 50 on each of the starboard and port sides of the towed vessel.

また、作業者は、一対の曳航ロープ２０を右舷及び左舷のそれぞれの挿通部５２に挿通させた後、図７Ｄに示すように、器材携行バッグ７０の開閉部材７２を開き、船尾用部材３０を器材携行バッグ７０から取り出し、船尾用部材３０を被曳航船の船尾に取り付ける。船尾用部材３０の下側接続部３３Ａに錘部材３３Ｂが取り付けられていれば、船尾用部材３０の下部を水中に沈め易くなり、船尾用部材３０を被曳航船の船尾に取り付ける作業が容易になる。なお、錘部材３３Ｂは、船尾用部材３０の下側接続部３３Ａに取り付けられた状態で器材携行バッグ７０に収容されていても良いし、作業者が、器材携行バッグ７０から取り出した船尾用部材３０の下側接続部３３Ａに、取付部７４から外した錘部材３３Ｂ（シャックル）を取り付けても良い。 Further, the operator inserts the pair of towing ropes 20 into the insertion portions 52 on the starboard side and the port side, and then opens the opening / closing member 72 of the equipment carrying bag 70 and opens the stern member 30 as shown in FIG. 7D. It is taken out from the equipment carrying bag 70, and the stern member 30 is attached to the stern of the towed ship. If the weight member 33B is attached to the lower connecting portion 33A of the stern member 30, the lower part of the stern member 30 can be easily submerged in water, and the work of attaching the stern member 30 to the stern of the towed ship can be easily performed. Become. The weight member 33B may be housed in the equipment carrying bag 70 in a state of being attached to the lower connecting portion 33A of the stern member 30, or the stern member taken out from the equipment carrying bag 70 by the operator. A weight member 33B (shackle) removed from the mounting portion 74 may be attached to the lower connecting portion 33A of the 30.

作業者は、船尾用部材３０を被曳航船の船尾に取り付けた後（船尾用部材３０を左右方向に広げた状態で船尾用部材３０の下部を水中に沈めた後）、船尾用部材３０の上縁の結索部３５（カラビナ）に曳航ロープ２０を挿通させるとともに、曳航ロープ２０を引っ張ることによって、船尾用部材３０の左右それぞれにおいて、上縁と下縁とを結び付ける。これにより、船尾用部材３０が袋状になり、被曳航船の船尾が船尾用部材３０に包み込まれるため、船尾用部材３０が船尾から外れにくくなる。なお、本実施形態では、図２に示すように、船尾用部材３０の下側の縁から曳航ロープ２０が延び出ているため、作業者が曳航ロープ２０を手繰ることによって船尾用部材３０の下縁が上縁の結索部３５に向かって引き寄せられるため、曳航ロープ２０を結索部３５（カラビナ）に挿通させる作業が容易である。 After attaching the stern member 30 to the stern of the towed ship (after submerging the lower part of the stern member 30 in water with the stern member 30 spread in the left-right direction), the worker attaches the stern member 30 to the stern member 30. The towing rope 20 is inserted through the tying portion 35 (carabiner) of the upper edge, and the towing rope 20 is pulled to connect the upper edge and the lower edge on each of the left and right sides of the stern member 30. As a result, the stern member 30 becomes bag-shaped, and the stern of the towed ship is wrapped in the stern member 30, so that the stern member 30 is less likely to come off the stern. In the present embodiment, as shown in FIG. 2, since the towing rope 20 extends from the lower edge of the stern member 30, the operator pulls the towing rope 20 by hand to obtain the stern member 30. Since the lower edge is pulled toward the tying portion 35 of the upper edge, the work of inserting the towing rope 20 into the tying portion 35 (carabiner) is easy.

作業者は、一対の曳航ロープ２０を右舷及び左舷のそれぞれの挿通部５２に挿通させた後、図１Ａに示すように、曳航ロープ２０の端部の一対の接続部２１を連結部材２３によって連結する。そして、作業者（若しくは、曳航船側の作業者）は、連結部材２３を介して、一対の曳航ロープ２０の端部と曳航船側の部材（例えば曳航船側の曳航ロープ２０の端部）とを連結することになる。 The operator inserts the pair of towing ropes 20 into the starboard and port insertion portions 52, and then connects the pair of connecting portions 21 at the ends of the towing rope 20 by the connecting member 23, as shown in FIG. 1A. do. Then, the worker (or the worker on the towing ship side) connects the end of the pair of towing ropes 20 and the member on the towing ship side (for example, the end of the towing rope 20 on the towing ship side) via the connecting member 23. Will be done.

上記の通り、本実施形態の器材携行バッグ７０に曳航部材１０を収容することによって、曳航部材１０を被曳航船にセットする作業が容易になる。 As described above, by accommodating the towing member 10 in the equipment carrying bag 70 of the present embodiment, the work of setting the towing member 10 on the towed ship becomes easy.

＜別の使用方法＞
図８Ａ及び図８Ｂは、曳航器材１及び器材携行バッグ７０の別の使用方法の説明図である。図８Ａ及び図８Ｂに示す被曳航船は、長さ３ｍ未満のいわゆるミニボートである。このように、曳航器材１は、水上オートバイとは別の小型の船舶の曳航にも使用可能である。 <Another usage>
8A and 8B are explanatory views of another usage of the towing equipment 1 and the equipment carrying bag 70. The towed vessels shown in FIGS. 8A and 8B are so-called mini-boats having a length of less than 3 m. As described above, the towing equipment 1 can also be used for towing a small vessel other than the personal watercraft.

図８Ａに示すように、作業車は、器材携行バッグ７０から中間ベルト９３を外した後に、中間ベルト９３の一端の雄部材と他端の雌部材とを連結することによって、被曳航船の船外機に中間ベルト９３を巻き付けて固定する。このとき、作業者は、中間ベルト９３の調整部９３Ａを調整することによって、被曳航船の船外機の大きさに適合させて中間ベルト９３を巻き付けることが可能である。また、作業者は、２本の中間ベルト９３を連結するとともに、連結した２本の中間ベルト９３を被曳航船の船外機に巻き付けることが可能である。 As shown in FIG. 8A, the work vehicle is a towed vessel by removing the intermediate belt 93 from the equipment carrying bag 70 and then connecting the male member at one end and the female member at the other end of the intermediate belt 93. The intermediate belt 93 is wound around the external unit and fixed. At this time, the operator can wind the intermediate belt 93 according to the size of the outboard motor of the towed vessel by adjusting the adjusting portion 93A of the intermediate belt 93. Further, the operator can connect the two intermediate belts 93 and wind the two connected intermediate belts 93 around the outboard motor of the towed ship.

また、図８Ａに示すように、作業者は、中間ベルト９３を被曳航船の船外機に巻き付けて固定した後に、中間ベルト９３の環状部材９３Ｂに曳航部材１０の固定部材３１Ｂ（カラビナ）を固定する。固定部材３１Ｂ（カラビナ）を中間ベルト９３の環状部材９３Ｂに固定することによって、固定部材３１Ｂ（カラビナ）を被曳航船に固定することができる。既に説明した通り、固定部材３１Ｂ（カラビナ）を被曳航船に固定することによって、曳航器材１を被曳航船にセットするときに曳航部材１０を水没させてしまうことを防止できる。なお、前述の使用方法と同様に、このとき、作業者は、器材携行バッグ７０の本体部７１を被曳航船側（前側）とし、開閉部材７２を外側（後側）に向けて、器材携行バッグ７０を被曳航船に固定する。これにより、開閉部材７２の開閉が容易になる。なお、図４に示すように、器材携行バッグ７０の外側には、曳航部材１０（詳しくは船尾用部材３０）の固定部３１が露出している。このため、作業者が固定部３１を被曳航船に固定する作業は容易である。 Further, as shown in FIG. 8A, the operator winds the intermediate belt 93 around the outboard motor of the towed ship and fixes it, and then attaches the fixing member 31B (carabiner) of the towing member 10 to the annular member 93B of the intermediate belt 93. Fix it. By fixing the fixing member 31B (carabiner) to the annular member 93B of the intermediate belt 93, the fixing member 31B (carabiner) can be fixed to the towed vessel. As described above, by fixing the fixing member 31B (carabiner) to the towed ship, it is possible to prevent the towing member 10 from being submerged when the towing equipment 1 is set on the towed ship. Similar to the above-mentioned usage method, at this time, the operator sets the main body 71 of the equipment carrying bag 70 to the towed ship side (front side) and the opening / closing member 72 to the outside (rear side), and the equipment carrying bag. Fix 70 to the towed vessel. This facilitates opening and closing of the opening / closing member 72. As shown in FIG. 4, the fixing portion 31 of the towing member 10 (specifically, the stern member 30) is exposed on the outside of the equipment carrying bag 70. Therefore, it is easy for the operator to fix the fixing portion 31 to the towed vessel.

固定部材３１Ｂ（カラビナ）を被曳航船に固定した後、作業者は、既に説明した使用方法（図７Ａ〜図７Ｄ参照）と同様の手順で、図８Ｂに示すように、曳航器材１を被曳航船にセットする。すなわち、まず、作業者は、被曳航船にベルト５０を巻き付ける。そして、作業者は、ベルト５０に設けられた挿通部５２に曳航ロープ２０を挿通するとともに、被曳航船の船尾に船尾用部材３０を取り付ける。なお、図８Ｂに示すように、船尾用部材３０は、船外機越しに船尾に取り付けても良い。これにより、ミニボートのような水上オートバイとは別の小型の船舶に対しても、曳航器材１を使用することができる。また、ミニボートのような水上オートバイとは別の小型の船舶に対しても、器材携行バッグ７０に曳航器材１を収容することによって、曳航器材１を被曳航船にセットする作業が容易になる。 After fixing the fixing member 31B (carabiner) to the towed vessel, the operator covers the towing equipment 1 as shown in FIG. 8B in the same procedure as the usage method (see FIGS. 7A to 7D) already described. Set on a towed ship. That is, first, the worker winds the belt 50 around the towed ship. Then, the operator inserts the towing rope 20 into the insertion portion 52 provided on the belt 50, and attaches the stern member 30 to the stern of the towed ship. As shown in FIG. 8B, the stern member 30 may be attached to the stern through the outboard motor. As a result, the towing equipment 1 can be used even for a small vessel such as a mini boat, which is different from the personal watercraft. Further, even for a small vessel such as a mini boat, which is different from the personal watercraft, by accommodating the towing equipment 1 in the equipment carrying bag 70, the work of setting the towing equipment 1 on the towed vessel becomes easy.
