ラッシングロッド21を用いてコンテナ31を固縛するには、図15に示すように、フック部材22をコーナ金具32の係合孔33に挿入してその係合孔33の周縁部にフック部材22を係合させた後、ラッシングロッド21の後端部を、甲板37に設けられた係合金具35に一端を係合させたターンバックル34に係合させ、ターンバックル34の締付けを行なうようにする。 To fasten the container 31 using the lashing rod 21, the hook member 22 is inserted into the engaging hole 33 of the corner fitting 32 and the hook member 22 is placed on the peripheral edge of the engaging hole 33 as shown in FIG. The rear end of the lashing rod 21 is engaged with the turnbuckle 34 having one end engaged with the engaging metal fitting 35 provided on the deck 37, so that the turnbuckle 34 is tightened. To do.

前記連結リング24は、その内周の先端部と後端部が円弧面24a、24bに形成された軸方向に細長い形状を呈している。 The connecting ring 24 has an axially elongated shape in which the front end portion and the rear end portion of the inner circumference thereof are formed on the arcuate surfaces 24a and 24b.

前記フック部材22は、コンテナ31の上下の4隅に設けられたコーナ金具32に形成された係合孔33に対して挿入可能で、コーナ金具32の係合孔33の周縁部に係合可能な係合ヘッド22aと、この係合ヘッド22aに対してL形に設けられたネック部22bと、このネック部22bの後端に設けられ、前記連結リング24の内側に挿入される連結板部22cと、この連結板部22cの後端に設けられ、連結板部22cを連結リング24から抜け止めする抜け止めピン22dとを備えている。 The hook member 22 can be inserted into the engaging holes 33 formed in the corner fittings 32 provided at the upper and lower four corners of the container 31, and can be engaged with the peripheral edge of the engaging holes 33 of the corner fittings 32. The engaging head 22a, the neck portion 22b provided in an L shape with respect to the engaging head 22a, and the connecting plate portion provided at the rear end of the neck portion 22b and inserted inside the connecting ring 24. It is provided with 22c and a retaining pin 22d provided at the rear end of the connecting plate portion 22c to prevent the connecting plate portion 22c from coming off from the connecting ring 24.

前記ラッシングロッド21を使用してコンテナ31の固縛を行うには、まず、図11に、二点鎖線で示すように、ロッド23を上方に持ち上げて、ロッド23に対して揺動自在に構成されたフック部材22の前端を下方に下げた状態にしてコーナ金具32の係合孔33に挿入する。その後、ロッド23の下端をターンバックル34に係合させて、ターンバックル34を回転させると、ロッド23に引張り力が付与され、ロッド23が引張り方向に向き、図10および図11に示すように、フック部材22の係合ヘッド22aが、コーナ金具32の係合孔33の周縁部に係合し、コンテナ31がラッシングロッド21によって固縛される。 In order to tie the container 31 using the lashing rod 21, first, as shown by the alternate long and short dash line in FIG. 11, the rod 23 is lifted upward so as to be swingable with respect to the rod 23. The front end of the hook member 22 is lowered and inserted into the engagement hole 33 of the corner fitting 32. After that, when the lower end of the rod 23 is engaged with the turnbuckle 34 and the turnbuckle 34 is rotated, a tensile force is applied to the rod 23, the rod 23 is oriented in the tensile direction, and as shown in FIGS. 10 and 11. , The engaging head 22a of the hook member 22 engages with the peripheral edge of the engaging hole 33 of the corner fitting 32, and the container 31 is fixed by the lashing rod 21.

次に、ラッシングロッド21によるコンテナ31の固縛を解除するには、ロッド23の下端のターンバックル34を緩めた後、図11に二点鎖線で示すように、ロッド23を斜め上方に持ち上げて、ロッド23に対して揺動自在に構成されたフック部材22の前端を下方に下げた状態にし、コーナ金具32の係合孔33からフック部材22の係合ヘッド22aを抜き取るようにする。 Next, in order to release the lashing of the container 31 by the lashing rod 21, after loosening the turnbuckle 34 at the lower end of the rod 23, the rod 23 is lifted diagonally upward as shown by the alternate long and short dash line in FIG. The front end of the hook member 22 which is swingably configured with respect to the rod 23 is lowered downward, and the engaging head 22a of the hook member 22 is pulled out from the engaging hole 33 of the corner metal fitting 32.

ところで、近年、船体の甲板上に積み重ねられるコンテナ31の積み重ね段数を多くするため、図16に示すように、甲板37上に船体の舷側方向に長く延びるラッシングブリッジ36を船体の長さ方向に間隔をおいて設け、そのラッシングブリッジ36間においてコンテナ31を多段に積み重ねることが行なわれている。 By the way, in recent years, in order to increase the number of stacking stages of containers 31 stacked on the deck of the hull, as shown in FIG. 16, lashing bridges 36 extending long in the side direction of the hull are spaced on the deck 37 in the length direction of the hull. The containers 31 are stacked in multiple stages between the lashing bridges 36.

この場合、積み重ね段数を多くしたコンテナ31の固縛力を高めるために、図16に示すように、隣り合うコーナ金具32に複数のラッシングロッド21のフック部材22が互いに近づくような状態で配置するエクスターナルラッシングと呼ばれるラッシング方法を採用している。 In this case, in order to increase the lashing force of the container 31 having a large number of stacking stages, as shown in FIG. 16, the hook members 22 of the plurality of lashing rods 21 are arranged in a state of approaching each other to the adjacent corner metal fittings 32. A lashing method called external lashing is used.

このエクスターナルラッシングで使用するラッシングロッド21として、従来、特許文献2の図4に示すものがある。 Conventionally, as the lashing rod 21 used in this external lashing, there is one shown in FIG. 4 of Patent Document 2.

このエクスターナルラッシングで使用するラッシングロッド21は、図12〜図14に示すように、フック部材22を構成する連結板部22cの前後方向の幅寸法を、ロッド23のロッド径の少なくとも2倍以上に延長させ、この延長させた連結板部22cの上面に、連結リング24の先端部の内周の円弧面24aが係合する係合凹部22eを前後方向に2個所設け、隣り合う他のラッシングロッド21、即ち、図12では後方側の二点鎖線で示すラッシングロッド21、図13では前方側の二点鎖線で示すラッシングロッド21が干渉しないように、連結リング24が係合する係合凹部22eの前後方向の位置を選択できるようにしている。 As shown in FIGS. 12 to 14, the lashing rod 21 used in this external lashing has a width dimension in the front-rear direction of the connecting plate portion 22c constituting the hook member 22 at least twice the rod diameter of the rod 23. On the upper surface of the extended connecting plate portion 22c, two engaging recesses 22e in which the arcuate surface 24a on the inner circumference of the tip of the connecting ring 24 is engaged are provided in the front-rear direction, and other lashing rods adjacent to each other are provided. 21, that is, the engaging recess 22e with which the connecting ring 24 is engaged so that the lashing rod 21 shown by the alternate long and short dash line on the rear side in FIG. 12 and the lashing rod 21 indicated by the alternate long and short dash line on the front side in FIG. 13 do not interfere with each other. The position in the front-back direction of is selectable.

ところが、エクスターナルラッシングで使用する従来のラッシングロッド21は、隣り合うラッシングロッド21の前後の位置によって、連結リング24が係合する係合凹部22eの前後方向の位置を、前方側か後方側かを選択する必要があり、隣り合うラッシングロッド21の前後の位置関係が変わると、連結リング24が係合する係合凹部22eの位置を変更しなければならない。 However, the conventional lashing rod 21 used in the external lashing determines whether the position of the engaging recess 22e with which the connecting ring 24 is engaged in the front-rear direction is the front side or the rear side, depending on the front-rear position of the adjacent lashing rods 21. It is necessary to select, and when the positional relationship between the front and rear of the adjacent lashing rods 21 changes, the position of the engaging recess 22e with which the connecting ring 24 engages must be changed.

しかしながら、係合凹部22eの前後の位置を変更するには、ターンバックル34をその都度緩め、連結リング24を、2つの係合凹部22eの間の凸部22fを乗り越えさせなければならず、ラッシングロッド21の前後の位置変更に手間がかかって、ラッシング作業に時間を要するという問題があった。 However, in order to change the front-rear position of the engaging recess 22e, the turnbuckle 34 must be loosened each time, and the connecting ring 24 must get over the convex portion 22f between the two engaging recesses 22e, which is lashing. There is a problem that it takes time to change the front and rear positions of the rod 21 and it takes time for the lashing work.

そこで、この発明は、フック部材の連結板部に対する連結リングの前後方向の位置を自動的に変更可能として、ラッシング作業の効率化を図ることを課題とするものである。 Therefore, it is an object of the present invention to improve the efficiency of lashing work by making it possible to automatically change the position of the connecting ring in the front-rear direction with respect to the connecting plate portion of the hook member.

前記の課題を解決するために、この発明は、ロッドと、このロッドの先端部に設けられ、ロッドに対して前後方向に揺動可能なフック部材とからなり、前記ロッドは、連結リングを先端部に有し、後端部にターンバックルの一端部が係合可能な係合部を有し、前記連結リングは、その内周の先端部と後端部が円弧面に形成された軸方向に細長い形状を呈し、前記フック部材は、コンテナの上下の4隅に設けられたコーナ金具に形成された係合孔に対して挿入可能で、コーナ金具の係合孔の周縁部に係合可能な係合ヘッドと、この係合ヘッドに対してL形に設けられたネック部と、このネック部の後端に設けられ、前記連結リングの内側に挿入される連結板部と、この連結板部の後端に設けられ、連結板部を連結リングから抜け止めする抜け止めピンとを備えるラッシングロッドにおいて、前記連結板部の前後方向の幅寸法を前記ロッド径の少なくとも2倍以上とし、前記連結リングの先端部内周の円弧面が接する前記連結板部の上面を平坦面に形成したことを特徴とする。 In order to solve the above problems, the present invention comprises a rod and a hook member provided at the tip of the rod and swingable in the front-rear direction with respect to the rod, and the rod has a connecting ring at the tip. The connecting ring has an engaging portion that is provided on the portion and one end of the turnback is engaged with the rear end portion, and the connecting ring has an axial direction in which the tip portion and the rear end portion of the inner circumference thereof are formed on an arc surface. The hook member has an elongated shape and can be inserted into the engaging holes formed in the corner fittings provided at the upper and lower four corners of the container, and can be engaged with the peripheral edge of the engaging holes of the corner fittings. An engaging head, a neck portion provided in an L shape with respect to the engaging head, a connecting plate portion provided at the rear end of the neck portion and inserted inside the connecting ring, and the connecting plate. In a lashing rod provided at the rear end of the portion and provided with a retaining pin for preventing the connecting plate portion from coming off from the connecting ring, the width dimension of the connecting plate portion in the front-rear direction is at least twice the rod diameter, and the connection is made. It is characterized in that the upper surface of the connecting plate portion in contact with the arc surface on the inner circumference of the tip portion of the ring is formed as a flat surface.

また、前記連結リングの後端部内周の円弧面の後端部に凹部を設け、この凹部に嵌る爪部を、前記連結板部の下面に設けることが望ましい。 Further, it is desirable that a recess is provided at the rear end of the arc surface on the inner circumference of the rear end of the connecting ring, and a claw portion that fits into the recess is provided on the lower surface of the connecting plate portion.

以上のように、この発明は、連結板部の上面を平坦面に形成して、連結板部の上面の平坦面に沿って連結リングを前後方向に、ロッド径の少なくとも2倍の範囲で任意の位置にずらすことができる。 As described above, in the present invention, the upper surface of the connecting plate portion is formed on a flat surface, and the connecting ring is arbitrarily formed in the front-rear direction along the flat surface of the upper surface of the connecting plate portion within a range of at least twice the rod diameter. Can be moved to the position of.

したがって、隣り合うラッシングロッドが干渉する位置にある場合、連結板部の上面の平坦面に沿って自動的に連結リングを前後方向にずれた位置に配置できるので、ラッシングロッドの前後の位置決めを特に行う必要がなく、エクスターナルラッシングが容易に行える。 Therefore, when the adjacent lashing rods are in a position where they interfere with each other, the connecting ring can be automatically arranged at a position shifted in the front-rear direction along the flat surface of the upper surface of the connecting plate portion. There is no need to do it, and external lashing can be done easily.

また、連結リングの後端部内周の円弧面の後端部に凹部を設け、この凹部に嵌る爪部を、連結板部の下面に設けることにより、ロッドを斜め上方に持ち上げる際に、連結リングの後端部内周の円弧面と連結板部の下面との接触部分が後方側にずれ動くことを防止することができるので、ロッドを斜め上方に持ち上げる角度が大きくならず、重量のあるラッシングロッドを持ち上げる作業員の負担を軽減することができる。 Further, by providing a recess at the rear end of the arc surface on the inner circumference of the rear end of the connecting ring and providing a claw portion that fits into the recess on the lower surface of the connecting plate portion, the connecting ring is used when the rod is lifted diagonally upward. Since the contact portion between the arc surface on the inner circumference of the rear end and the lower surface of the connecting plate can be prevented from shifting to the rear side, the angle at which the rod is lifted diagonally upward is not increased, and the heavy lashing rod is used. The burden on the worker who lifts the rod can be reduced.

There is no need to do it, and external lashing can be done easily.

前記ラッシングロッド1を使用してコンテナ31の固縛を行うには、まず、図8に二点鎖線で示すように、ロッド3を上方に持ち上げて、ロッド3に対して揺動自在に構成されたフック部材2の前端を下方に下げた状態にしてコーナ金具32の係合孔33に挿入する。その後、ロッド3の下端をターンバックル34に係合させて、ターンバックル34を回転させると、ロッド3に引張り力が付与され、ロッド3が引張り方向に向き、図5および図8に実線で示すように、フック部材2の係合ヘッド2aが、コーナ金具32の係合孔33の周縁部に係合し、コンテナ31がラッシングロッド1によって固縛される。 In order to tie the container 31 using the lashing rod 1, first, as shown by the alternate long and short dash line in FIG. 8, the rod 3 is lifted upward so as to be swingable with respect to the rod 3. The front end of the hook member 2 is lowered and inserted into the engagement hole 33 of the corner fitting 32. After that, when the lower end of the rod 3 is engaged with the turnbuckle 34 and the turnbuckle 34 is rotated, a tensile force is applied to the rod 3, the rod 3 is oriented in the tensile direction, and is shown by a solid line in FIGS. 5 and 8. As described above, the engaging head 2a of the hook member 2 engages with the peripheral edge of the engaging hole 33 of the corner fitting 32, and the container 31 is fixed by the lashing rod 1.

次に、ラッシングロッド1によるコンテナ31の固縛を解除するには、ロッド3の下端のターンバックル34を緩めた後、図8に二点鎖線で示すように、ロッド3を斜め上方に持ち上げて、ロッド3に対して揺動自在に構成されたフック部材2の前端を下方に下げた状態にし、コーナ金具32の係合孔33からフック部材2の係合ヘッド2aを、コーナ金具32の係合孔33から抜き取るようにする。 Next, in order to release the lashing of the container 31 by the lashing rod 1, after loosening the turnbuckle 34 at the lower end of the rod 3, the rod 3 is lifted diagonally upward as shown by the alternate long and short dash line in FIG. With the front end of the hook member 2 swingably configured with respect to the rod 3 lowered downward, the engagement head 2a of the hook member 2 is engaged with the corner metal fitting 32 from the engagement hole 33 of the corner metal fitting 32. Try to pull out from the hole 33.

図8に二点鎖線で示すように、フック部材2の係合ヘッド2aを、コーナ金具32の係合孔33に挿入し、また、コーナ金具32の係合孔33から抜き取る際には、ロッド3を斜め上方に持ち上げて、ロッド3に対して揺動自在に構成されたフック部材2の前端を下方に下げた状態にしなければならない。 As shown by the alternate long and short dash line in FIG. 8, when the engaging head 2a of the hook member 2 is inserted into the engaging hole 33 of the corner fitting 32 and pulled out from the engaging hole 33 of the corner fitting 32, the rod is used. 3 must be lifted diagonally upward so that the front end of the hook member 2 swingably configured with respect to the rod 3 is lowered downward.

前記ロッド3を斜め上方に持ち上げて、ロッド3に対して揺動自在に構成されたフック部材2の前端を下方に下げた状態にする場合に、前記連結リング4の後端部内周の円弧面4bと連結板部2cの下面との接触部分が後方側にずれ動くと、ロッド3を斜め上方に持ち上げる角度が大きくなって、重量のあるラッシングロッド1を持ち上げる作業員の負担が大きく、作業が非常にやりずらくなる。 When the rod 3 is lifted diagonally upward to bring the front end of the hook member 2 swingably configured with respect to the rod 3 downward, the arcuate surface of the inner circumference of the rear end of the connecting ring 4. When the contact portion between 4b and the lower surface of the connecting plate portion 2c shifts to the rear side, the angle at which the rod 3 is lifted diagonally upward becomes large, and the burden on the worker who lifts the heavy lashing rod 1 becomes heavy. It's very difficult to do.

この発明では、ロッド3を斜め上方に持ち上げる際に、連結リング4の後端部内周の円弧面4bと連結板部2cの下面との接触部分が後方側にずれ動くことを防止するために、連結リング4の後端部内周の円弧面4bの後方に凹部4cを設け、この凹部4cに嵌る爪部2fを、連結板部2cの下面に設けている。 In the present invention, in order to prevent the contact portion between the arc surface 4b on the inner circumference of the rear end portion of the connecting ring 4 and the lower surface of the connecting plate portion 2c from shifting to the rear side when the rod 3 is lifted diagonally upward. A recess 4c is provided behind the arc surface 4b on the inner circumference of the rear end portion of the connecting ring 4, and a claw portion 2f that fits into the recess 4c is provided on the lower surface of the connecting plate portion 2c.

以上、この発明の実施の形態について説明を行ったが、この発明はこうした実施の形態に何等限定されるものではなく、あくまで例示であって、この発明の要旨を逸脱しない範囲内において、さらに種々なる形態で実施し得る。 Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, but is merely an example, and is further various as long as it does not deviate from the gist of the present invention.
