Description

横型空気式防舷材用の保護カバーおよび横型空気式防舷材並びに横型空気式防舷材の使用方法Protective cover for horizontal pneumatic fender, horizontal pneumatic fender and method of using horizontal pneumatic fender
　本発明は、横型空気式防舷材用の保護カバーおよび横型空気式防舷材並びに横型空気式防舷材の使用方法に関し、さらに詳しくは、水面に浮遊する油が付着して防舷材が膨潤劣化することを抑制できる横型空気式防舷材用の保護カバーおよび横型空気式防舷材並びに横型空気式防舷材の使用方法に関するものである。 The present invention relates to a protective cover for a horizontal pneumatic fender, a horizontal pneumatic fender, and a method of using the horizontal pneumatic fender, and more specifically, the fouling material adheres to oil floating on the water surface. The present invention relates to a protective cover for a horizontal pneumatic fender capable of suppressing swelling deterioration, a horizontal pneumatic fender, and a method of using the horizontal pneumatic fender.
　船舶の接岸時における船体および岸壁の損傷防止等を目的として、岸壁の壁面または舷側に設置される空気式防舷材が知られている。空気式防舷材は、補強材が埋設されたゴムにより形成された中空体である。その中空内部には、空気が封入されていて船舶の接岸時には、封入された空気によって生じる弾性力により、その衝撃を緩和する。 Pneumatic fenders installed on the quay walls or on the shore side are known for the purpose of preventing damage to the hull and quay when the ship is berthing. The pneumatic fender is a hollow body made of rubber in which a reinforcing material is embedded. The inside of the hollow is filled with air, and when the ship touches the shore, the impact is mitigated by the elastic force generated by the enclosed air.
　空気式防舷材の形態は、横型と縦型との２種類に大別することができる。横型空気式防舷材は、長手方向を横にした状態で水に浮かべて使用される。縦型空気式防舷材は、中空内部に所定量の水を収容することで、一部を水中に沈めて長手方向を縦にした立設状態で水に浮かべて使用される。 The form of pneumatic fenders can be broadly divided into two types: horizontal and vertical. The horizontal pneumatic fender is used by floating in water with the longitudinal direction being horizontal. The vertical pneumatic fender is used by suspending a predetermined amount of water in the hollow interior and floating on the water in a standing state in which a part thereof is submerged in water and the longitudinal direction is vertical.
　ところで、空気式防舷材を設置した水域に油が漂着して滞留する場合、空気式防舷材の外面には水面に浮遊する油が付着した状態になる。従来の空気式防舷材には、このような油に対する考慮がされていないため、この状態が長時間続くと油が付着した部分のゴムが膨潤して劣化する。これにより、空気式防舷材は使用できなくなり耐用期間が短くなるという問題がある。 By the way, when oil strays and stays in the water area where the pneumatic fender is installed, the oil floating on the water surface is attached to the outer surface of the pneumatic fender. Since the conventional pneumatic fender does not consider such oil, when this state continues for a long time, the rubber on the part where the oil adheres swells and deteriorates. As a result, there is a problem that the pneumatic fender cannot be used and the service life is shortened.
　横型空気式防舷材については、防舷材の外面を覆うシート状の保護部材が提案されている（例えば、特許文献１参照）。しかしながら、この保護部材は、船体等との接触に起因する防舷材の外傷を防止することを目的としたものであり、上述した油による膨潤劣化を意図したものではなかった。そして、この保護部材を防舷材に装着すると、周方向には継ぎ目があり、左右両端部には切れ目が存在する。横型空気式防舷材は使用中に鏡部の中心軸まわりに回転するので、この保護部材を装着しても上記の継ぎ目や切れ目を通じて、水面に浮遊する油が防舷材の外面に付着する。それ故、この保護部材では、防舷材の膨潤劣化を抑制することは困難であった。 For the horizontal pneumatic fender, a sheet-like protective member that covers the outer surface of the fender has been proposed (see, for example, Patent Document 1). However, this protective member is intended to prevent damage to the fenders caused by contact with the hull or the like, and is not intended for swelling deterioration due to the oil described above. When this protective member is attached to the fender, there are seams in the circumferential direction, and there are cuts at the left and right ends. Since the horizontal pneumatic fender rotates around the central axis of the mirror during use, oil floating on the water surface adheres to the outer surface of the fender through the joints and cuts even when this protective member is installed. . Therefore, with this protective member, it has been difficult to suppress swelling deterioration of the fender.

　保護層体が、前記胴体部全体の外面およびそれぞれの鏡部全体の外面を被覆する構成にすると、実質的に防舷材の全体の外面が、保護層体によって、水面に浮遊する油から保護される。これにより、防舷材の膨潤劣化を抑制するには一段と有利になる。 When the protective layer body covers the outer surface of the entire body part and the outer surface of the entire mirror part, the entire outer surface of the fender is substantially protected from oil floating on the water surface by the protective layer body. Is done. Thereby, it becomes more advantageous to suppress the swelling deterioration of the fender.
　保護層体が、耐油性部材により形成される構成にすると、保護層体により被覆した範囲の膨潤劣化を防止するには有利になる。耐油性部材としては、例えば、アクリロニトリル・ブタジエンゴムを含有する弾性部材を用いる。 When the protective layer body is formed of an oil-resistant member, it is advantageous to prevent swelling deterioration in a range covered with the protective layer body. As the oil resistant member, for example, an elastic member containing acrylonitrile-butadiene rubber is used.

　以下、本発明の横型空気式防舷材用の保護カバーおよび横型空気式防舷材並びに横型空気式防舷材の使用方法を、図に示した実施形態に基づいて説明する。 Hereinafter, a protective cover for a horizontal pneumatic fender according to the present invention, a horizontal pneumatic fender, and a method of using the horizontal pneumatic fender will be described based on the embodiments shown in the drawings.
　従来の横型空気式防舷材１Ａ（以下、防舷材１Ａという）は、図７に例示するように、円筒状の胴体部１ａと、胴体部１ａの左右両端に連接されたボウル状の鏡部１ｂとを備えている。右側、左側の鏡部１ｂにはそれぞれ口金部１ｃ、口金部１ｄが設けられている。一方側の鏡部１ｂに口金部１ｃのみが設けられることもある。 A conventional horizontal pneumatic fender 1A (hereinafter referred to as fender 1A) includes, as illustrated in FIG. 7, a cylindrical body 1a and bowl-shaped mirrors connected to the left and right ends of the body 1a. Part 1b. A base part 1c and a base part 1d are provided on the right and left mirror parts 1b, respectively. Only the base part 1c may be provided in the mirror part 1b on one side.
　胴体部１ａおよび鏡部１ｂは、内層ゴムと外層ゴムとの間に複数の補強層が積層された部材で構成されている。胴体部１ａと鏡部１ｂとにより形成された中空の内部空間に空気Ａが充填される。図面では、胴体部１ａと鏡部１ｂとの境界を二点鎖線で示している。 The body part 1a and the mirror part 1b are configured by a member in which a plurality of reinforcing layers are laminated between an inner layer rubber and an outer layer rubber. Air A is filled in a hollow internal space formed by the body portion 1a and the mirror portion 1b. In the drawing, the boundary between the body portion 1a and the mirror portion 1b is indicated by a two-dot chain line.
　口金部１ｃには、空気Ａを注入するための注入口や防舷材１Ａの内圧が過大になることを防止する安全弁、この内圧を測定する圧力センサ等が設けられている。それぞれの口金部１ｃ、１ｄには別々のガイチェーン５の一端部が接続されている。 The base part 1c is provided with an inlet for injecting air A, a safety valve for preventing the internal pressure of the fender 1A from becoming excessive, a pressure sensor for measuring the internal pressure, and the like. One end of a separate guy chain 5 is connected to each of the cap parts 1c and 1d.
　防舷材１Ａを岸壁の壁面または舷側に設置する際には、口金部１ｃ、１ｄに接続されているそれぞれのガイチェーン５の他端部を、それぞれ岸壁または船体に固定する。そして、中空の内部空間に空気Ａが収容された防舷材１Ａを、長手方向（胴体部１ａの筒軸方向）を横にした状態で海等に浮かべて設置する。 When the fender 1A is installed on the quay wall or on the berth side, the other end of each guy chain 5 connected to the base parts 1c, 1d is fixed to the quay or the hull, respectively. Then, the fender 1A in which the air A is accommodated in the hollow internal space is placed floating in the sea or the like with the longitudinal direction (the cylinder axis direction of the body portion 1a) lying sideways.
　そのため、防舷材１Ａを設置した水域に油Ｃが漂流して滞留すると、水面に浮遊する油Ｃが常に胴体部１ａおよび鏡部１ｂに接触する。このまま防舷材１Ａを使用し続けると、胴体部１ａおよび鏡部１ｂを形成している外層ゴムが油Ｃによって膨潤する。この膨潤によって胴体部１ａおよび鏡部１ｂの強度低下等が発生し、防舷材１Ａを使用することが不可能になる。 Therefore, when the oil C drifts and stays in the water area where the fender 1A is installed, the oil C floating on the water surface always contacts the body 1a and the mirror 1b. If the fender 1A continues to be used as it is, the outer layer rubber forming the body portion 1a and the mirror portion 1b swells with the oil C. Due to this swelling, the strength of the body part 1a and the mirror part 1b is reduced, and it becomes impossible to use the fender 1A.
　そこで、図１、２に例示する本発明の横型空気式防舷材用の保護カバー２（以下、保護カバー２という）を用いる。この保護カバー２は、少なくとも胴体部１ａ全体の外面およびそれぞれの鏡部１ｂにおける半径方向外側で鏡部１ｂの総面積の半分の面積となる外面の領域を被覆する保護層体３と、保護層体３を防舷材１Ａの所定位置に配置する取り付け部４とを備えている。 Therefore, the protective cover 2 (hereinafter referred to as the protective cover 2) for the horizontal pneumatic fender according to the present invention illustrated in FIGS. The protective cover 2 includes a protective layer body 3 that covers at least an outer surface of the entire body portion 1a and an outer surface area that is half the total area of the mirror portion 1b on the radially outer side of each mirror portion 1b, and a protective layer. And an attachment portion 4 for disposing the body 3 at a predetermined position of the fender 1A.
　保護層体３は、ゴム等の弾性部材や樹脂等を層状に薄く形成したシートであり、その厚さは例えば１ｍｍ以上３０ｍｍ以下である。保護層体３は、実質的に水が染み込まない仕様になっている。筒状の保護層体３は、周方向にも筒軸方向にも切れ目がなく連続している。保護層体３は例えば、部材を筒状に一体成形して製造する。或いは、複数の部材を接合して筒状の保護層体３を製造する。この場合は、それぞれの部材の接合継ぎ目は、すき間が生じない加工を施して油Ｃが通過しない仕様にする。防舷材１Ａに外挿された筒状の保護層体３により、少なくとも胴体部１ａ全体の外面およびそれぞれの鏡部１ｂにおける半径方向外側で鏡部１ｂの総面積の半分の面積となる外面の領域が被覆される。尚、鏡部１ｂの総面積とは口金部１ｃ、１ｄの面積を含まない。 The protective layer body 3 is a sheet in which an elastic member such as rubber or a resin is thinly formed in a layer shape, and the thickness thereof is, for example, 1 mm or more and 30 mm or less. The protective layer body 3 has a specification that substantially does not soak water. The cylindrical protective layer body 3 is continuous without any breaks in both the circumferential direction and the cylinder axis direction. The protective layer body 3 is manufactured, for example, by integrally molding a member into a cylindrical shape. Alternatively, the cylindrical protective layer body 3 is manufactured by joining a plurality of members. In this case, the joint seam of each member is processed so as not to generate a gap so that the oil C does not pass. By the cylindrical protective layer body 3 extrapolated to the fender 1A, at least the outer surface of the entire body portion 1a and the outer surface that is half the total area of the mirror portion 1b on the radially outer side of each mirror portion 1b. The area is covered. The total area of the mirror part 1b does not include the areas of the base parts 1c and 1d.
　保護層体３により被覆される鏡部１ｂの領域をより具体的に述べると、図２に例示するように、鏡部１ｂの外縁から半径方向内側に寸法Ｈまでの円環状の領域である。この寸法Ｈは例えば１ｍ以上、より好ましくは２ｍ以上に設定される。それぞれの鏡部１ｂの総面積の半分以上の面積を保護層体３により被覆するとよい。 More specifically, the region of the mirror portion 1b covered with the protective layer body 3 is an annular region from the outer edge of the mirror portion 1b to the dimension H radially inward as illustrated in FIG. The dimension H is set to, for example, 1 m or more, more preferably 2 m or more. The protective layer body 3 may cover an area that is at least half of the total area of each mirror portion 1b.
　保護層体３は、耐油性部材を用いて形成することも、非耐油性部材を用いても形成することもできる。また、弾性部材を用いて保護層体３を形成することも、非弾性部材を用いて保護層体３を形成することもできる。例えば、耐油性に優れたアクリロニトリル・ブタジエンゴムを含有する弾性部材を用いて保護層体３を形成する。耐油性を有する弾性部材としては、他にもフッ素ゴム、クロロプレンゴム、塩素化ポリエチレンゴム等を例示できる。 The protective layer body 3 can be formed using an oil-resistant member or a non-oil-resistant member. Moreover, the protective layer body 3 can be formed using an elastic member, or the protective layer body 3 can be formed using a non-elastic member. For example, the protective layer body 3 is formed using an elastic member containing acrylonitrile-butadiene rubber excellent in oil resistance. Other examples of the elastic member having oil resistance include fluorine rubber, chloroprene rubber, and chlorinated polyethylene rubber.
　保護層体３の内面と胴体部１ａおよび鏡部１ｂの外面との間は、多少のすき間がある状態にすることも、すき間なく密着させた状態にすることもできる。保護層体３が弾性部材により形成されていると、筒状の保護層体３を拡径させて胴体部１ａおよび鏡部１ｂに外挿させることで、保護層体３の内面と胴体部１ａの外面とを密着させることができる。 Between the inner surface of the protective layer body 3 and the outer surfaces of the body portion 1a and the mirror portion 1b, there can be a slight gap or a close contact state. If the protective layer body 3 is formed of an elastic member, the inner diameter of the protective layer body 3 and the body portion 1a are increased by expanding the cylindrical protective layer body 3 and extrapolating the body portion 1a and the mirror portion 1b. Can be brought into close contact with the outer surface.
　取り付け部４としては例えば、防舷材１Ａに外挿させた保護層体３と右側の鏡部１ｂ側とを接続する紐状体４ｂ（右側の紐状体４ｂ）およびこの保護層体３と左側の鏡部１ｂ側とを接続する紐状体４ｂ（左側の紐状体４ｂ）を用いる。右側の紐状体４ｂによって、保護層体３の右端部と右側の鏡部１ｂの表面とを直接接続する、または、保護層体３の右端部と右側の鏡部１ｂに設けられた口金部１ｂとを接続する。左側の紐状体４ｂによって、保護層体３の左端部と左側の鏡部１ｂの表面とを直接接続する、または、保護層体３の左端部と左側の鏡部１ｂに設けられた口金部１ｄとを接続する。 As the attachment part 4, for example, a string-like body 4b (right-side string-like body 4b) that connects the protective layer body 3 extrapolated to the fender 1A and the right mirror part 1b side, and the protective layer body 3 A string-like body 4b (left-side string-like body 4b) that connects the left mirror part 1b side is used. The right end of the protective layer 3 and the surface of the right mirror 1b are directly connected by the right string 4b, or the cap provided on the right end of the protective layer 3 and the right mirror 1b. 1b is connected. The left end of the protective layer body 3 and the surface of the left mirror part 1b are directly connected by the left string-like body 4b, or the base part provided on the left end part of the protective layer body 3 and the left mirror part 1b. 1d is connected.
　この実施形態では、右側の紐状体４ｂの一端部は、接続部材４ａを介して保護層体３の右端開口縁部に接続されている。右側の紐状体４ｂの他端部は、口金部１ｃに外嵌された固定部材４ｃを介して口金部１ｃに接続されている。左側の紐状体４ｂの一端部は、接続部材４ａを介して保護層体３の左端開口縁部に接続されている。左側の紐状体４ｂの他端部は、口金部１ｄに外嵌された固定部材４ｃを介して口金部１ｄに接続されている。 In this embodiment, one end portion of the right string 4b is connected to the right end opening edge of the protective layer body 3 via the connection member 4a. The other end of the right string 4b is connected to the base part 1c via a fixing member 4c fitted on the base part 1c. One end of the left string 4b is connected to the left edge of the protective layer 3 through the connecting member 4a. The other end of the left string 4b is connected to the base part 1d via a fixing member 4c fitted on the base part 1d.
　紐状体４ｂとしては、樹脂製や天然繊維製のロープや金属チェーン等を用いることができる。紐状体４ｂとして樹脂製や天然繊維製のロープを用いると、紐状体４ｂに起因して鏡部１ｂの表面に傷が生じることを防止するには有利になる。 As the string-like body 4b, a rope made of resin or natural fiber, a metal chain, or the like can be used. Using a rope made of resin or natural fiber as the string-like body 4b is advantageous for preventing the surface of the mirror portion 1b from being damaged due to the string-like body 4b.
　この保護カバー２を使用する場合、中空の内部空間に空気Ａが収容された防舷材１Ａに地上や船上で保護カバー２を取り付ける。その後、図１に例示するように防舷材１Ａを岸壁の壁面または舷側に設置する。それぞれの鏡部１ｂにおける保護層体３の内周縁の下端位置を水面位置よりも高い位置に設定する。 When this protective cover 2 is used, the protective cover 2 is attached to the fender 1A in which air A is housed in a hollow internal space on the ground or on the ship. Thereafter, as illustrated in FIG. 1, the fender 1 </ b> A is installed on the quay wall or on the shore side. The lower end position of the inner peripheral edge of the protective layer body 3 in each mirror part 1b is set to a position higher than the water surface position.
　防舷材１Ａを設置した水域に油Ｃが漂流してきて防舷材１Ａの周囲が水面に浮遊する油Ｃで囲まれると、保護層体３の外面に油Ｃが付着した状態が続く。胴体部１ａおよび鏡部１ｂ半径方向外側のある程度の領域は保護層体３によって被覆されているので、防舷材１Ａが筒軸心を中心にして回転しても油Ｃが付着することがなく、油Ｃとは隔絶される。油Ｃは水面に伴って変動するが、港湾等での平時の水面の上下変動は１～２ｍ程度である。また、防舷材１Ａはある程度、波（水面）と同調して上下移動する。したがって、水面位置の上下変動範囲は横置状態になっている胴体部１ａの下端部になる。 When the oil C drifts in the water area where the fender 1A is installed and the periphery of the fender 1A is surrounded by the oil C floating on the water surface, the state where the oil C adheres to the outer surface of the protective layer 3 continues. Since a certain area outside the body portion 1a and the mirror portion 1b in the radial direction is covered with the protective layer 3, the oil C does not adhere even if the fender 1A rotates around the cylinder axis. , Isolated from oil C. Oil C fluctuates with the water surface, but the vertical fluctuation of the water surface during normal times at a port etc. is about 1 to 2 m. Further, the fender 1A moves up and down to some extent in synchronization with the wave (water surface). Therefore, the up-and-down fluctuation range of the water surface position is the lower end portion of the body portion 1a that is in the horizontal state.
　保護層体３の内面と胴体部１ａおよび鏡部１ｂの外面との間に多少のすき間があっても、水面位置がそれぞれの鏡部１ｂにおける保護層体３の内周縁の下端位置を超えなければ、両者のすき間に油Ｃが入り込むことはない。したがって、波が平時よりも高い場合を除いて、防舷材１Ａの保護層体３により被覆された範囲は油Ｃと隔絶され、平時においては防舷材１Ａに油Ｃが付着することを回避できる。平時でない時（波が高い時）は防舷材１Ａの使用を控えるとよい。それ故、本発明の保護カバー２を用いることにより、水面に浮遊する油Ｃによる防舷材１Ａの膨潤劣化を効果的に抑制できる。 Even if there are some gaps between the inner surface of the protective layer body 3 and the outer surfaces of the body part 1a and the mirror part 1b, the water surface position must not exceed the lower end position of the inner peripheral edge of the protective layer body 3 in each mirror part 1b. In this case, oil C does not enter between the gaps. Therefore, unless the wave is higher than normal, the area covered with the protective layer 3 of the fender 1A is isolated from the oil C, and the oil C is prevented from adhering to the fender 1A in normal times. it can. When it is not normal (when the wave is high), it is better to refrain from using the fender 1A. Therefore, by using the protective cover 2 of the present invention, the swelling deterioration of the fender 1A due to the oil C floating on the water surface can be effectively suppressed.
　また、層状の薄い保護層体３を用いるので、防舷材１Ａに保護カバー２を取り付けて使用しても防舷材１Ａの圧縮および復元変形が大幅に困難になることもない。したがって、保護カバー２によって防舷材１Ａの衝撃緩和性能等に実質的な悪影響は生じない。 Further, since the thin protective layer body 3 is used, even when the protective cover 2 is attached to the fender 1A, the fender 1A is not significantly difficult to be compressed and restored. Therefore, the protective cover 2 does not cause a substantial adverse effect on the impact mitigation performance of the fender 1A.
　非耐油性部材により保護層体３を形成すると、耐油性部材により形成した場合に比して、付着した油Ｃによって保護層体３は早期に膨潤等により劣化する。そのため、保護層体３の劣化を発見した際、或いは、予め設定された期間経過後に、劣化した保護層体３を防舷材１Ａから取り外して新しい保護層体３に交換する。或いは、新しい保護カバー２に交換してもよい。 When the protective layer body 3 is formed of a non-oil resistant member, the protective layer body 3 is deteriorated due to swelling or the like earlier due to the oil C adhering than when the protective layer body 3 is formed of an oil resistant member. Therefore, when the deterioration of the protective layer body 3 is discovered or after a preset period has elapsed, the deteriorated protective layer body 3 is removed from the fender 1A and replaced with a new protective layer body 3. Alternatively, the protective cover 2 may be replaced with a new one.
　耐油性部材により保護層体３を形成すると、非耐油性部材により形成した場合に比して長期に渡って、保護層体３により被覆した範囲の膨潤劣化を防止することができる。それ故、新しい保護層体３（保護カバー２）に交換する必要がなくなる。或いは新しい保護層体３（保護カバー２）への交換頻度を少なくすることができる。 When the protective layer body 3 is formed of an oil resistant member, it is possible to prevent swelling deterioration in a range covered with the protective layer body 3 over a long period of time as compared with the case of forming it with a non-oil resistant member. Therefore, it is not necessary to replace with a new protective layer body 3 (protective cover 2). Alternatively, the frequency of replacement with a new protective layer body 3 (protective cover 2) can be reduced.
　保護層体３の内面と胴体部１ａおよび鏡部１ｂの外面とが密着していると、保護層体３が防舷材１Ａに対してずれ難くなるという利点がある。これに伴って、取り付け部４の強度を低く設定することも可能になる。また、水面位置がそれぞれの鏡部１ｂにおける保護層体３の内周縁の下端位置を超えた場合であっても、保護層体３と鏡部１ｂの間から油Ｃが浸入し難くなる。保護層体３の内面と胴体部１ａおよび鏡部１ｂの外面とを密着させる場合には、保護層体３を防舷材１Ａの圧縮および復元変形に追従することができる弾性部材により形成するとよい。 If the inner surface of the protective layer body 3 is in close contact with the outer surfaces of the body portion 1a and the mirror portion 1b, there is an advantage that the protective layer body 3 is difficult to be displaced with respect to the fender 1A. Along with this, the strength of the attachment portion 4 can be set low. Further, even when the water surface position exceeds the lower end position of the inner peripheral edge of the protective layer body 3 in each mirror portion 1b, the oil C hardly enters between the protective layer body 3 and the mirror portion 1b. When the inner surface of the protective layer body 3 and the outer surfaces of the body portion 1a and the mirror portion 1b are brought into close contact with each other, the protective layer body 3 may be formed of an elastic member that can follow the compression and decompression deformation of the fender 1A. .
　保護層体３の内面と胴体部１ａおよび鏡部１ｂの外面との間にすき間を設けていると、保護層体３によって防舷材１Ａの圧縮および復元変形が影響を受け難くなるという利点がある。また、防舷材１Ａの圧縮および復元変形に追従するために要求される伸縮性等が低くなるので、保護層体３として採用できる部材の選択肢が広がる。 If a gap is provided between the inner surface of the protective layer body 3 and the outer surfaces of the body portion 1a and the mirror portion 1b, the protective layer body 3 has an advantage that the compression and decompression deformation of the fender 1A is hardly affected. is there. Moreover, since the elasticity etc. requested | required in order to follow the compression and decompression deformation | transformation of the fender 1A become low, the choice of the member which can be employ | adopted as the protective layer body 3 spreads.
　上述した実施形態では、それぞれの鏡部１ｂの一部の外面は保護層体３により被覆されているが、保護層体３に被覆されずに露出している部分がある。そこで、図３、４に例示する保護カバー２の実施形態では、保護層体３が、胴体部１ａ全体の外面およびそれぞれの鏡部１ｂ全体の外面を被覆する構成になっている。 In the above-described embodiment, a part of the outer surface of each mirror portion 1b is covered with the protective layer body 3, but there is a portion exposed without being covered with the protective layer body 3. Therefore, in the embodiment of the protective cover 2 illustrated in FIGS. 3 and 4, the protective layer body 3 is configured to cover the outer surface of the entire body portion 1a and the outer surface of the entire mirror portion 1b.
　この保護層体３は、先の実施形態とは防舷材１Ａを被覆する範囲（保護層体３の防舷材１Ａに対する大きさ）のみが異なる。 This protective layer body 3 differs from the previous embodiment only in the range in which the fender 1A is covered (the size of the protective layer 3 with respect to the fender 1A).
　この実施形態の取り付け部４は、締め付けバンド４ｄと、締め金具４ｅとで構成されている。締め付けバンド４ｄは、筒状の保護層体３の右端、左端のそれぞれの開口を締め付けてそれぞれ口金部１ｃ、１ｄに固定する。締め金具４ｅは、締め付けバンド４ｄを所定長さで締め付け固定し、また、その解除行う。 The mounting portion 4 of this embodiment is composed of a fastening band 4d and a fastening metal 4e. The fastening band 4d fastens the openings at the right end and the left end of the cylindrical protective layer body 3 and fixes them to the base portions 1c and 1d, respectively. The fastener 4e fastens and fixes the fastening band 4d with a predetermined length and releases it.
　この保護カバー２を防舷材１Ａの所定位置に配置するには、保護層体３を防舷材１Ａ（胴体部１ａおよびそれぞれの鏡部１ｂ）に外挿した後、保護層体３の右端、左端それぞれの開口を取り付け部４によって締め付けて口金部１ｃ、１ｄに取り付ける。 In order to dispose the protective cover 2 at a predetermined position of the fender 1A, after the protective layer body 3 is extrapolated to the fender 1A (the body part 1a and the respective mirror part 1b), the right end of the protective layer body 3 is placed. The openings at the left ends are fastened by the attachment part 4 and attached to the base parts 1c and 1d.
　この実施形態によれば、実質的に防舷材１Ａの全体の外面が、保護層体３によって、水面に浮遊する油Ｃから隔絶されて保護される。これにより、防舷材１Ａの膨潤劣化を抑制するには一段と有利になる。 According to this embodiment, substantially the entire outer surface of the fender 1A is isolated and protected from the oil C floating on the water surface by the protective layer body 3. Thereby, it becomes more advantageous to suppress the swelling deterioration of the fender 1A.
　この実施形態においても、先の実施形態で述べた種々の構成を採用することができる。また、使用方法や交換についても先の実施形態と同様に行うことができる。 Also in this embodiment, various configurations described in the previous embodiment can be adopted. Also, the method of use and replacement can be performed in the same manner as in the previous embodiment.
　また、本発明の横型空気式防舷材１（以下、防舷材１という）は、従来の防舷材１Ａに対して上述した種々の保護層体３を着脱自在に備えたものである。 Further, the horizontal pneumatic fender 1 of the present invention (hereinafter referred to as fender 1) is provided with the above-mentioned various protective layer bodies 3 detachably with respect to the conventional fender 1A.
　防舷材１の別の実施形態を図５に例示する。 Another embodiment of the fender 1 is illustrated in FIG.
　この防舷材１は、少なくとも胴体部１ａ全体の外面およびそれぞれの鏡部１ｂにおける半径方向外側で鏡部１ｂの総面積の半分の面積となる外面の領域を被覆する保護層体３を備えていて、この保護層体３が加硫接着によって防舷材１として一体化している。即ち、保護層体３の内面が、対向する面とすき間なく密着固定されている。従来の防舷材１Ａの外面に保護層体３を追加的に加硫接着することも、従来の防舷材１Ａの外層ゴムに置き換えて保護層体３を加硫接着することもできる。 The fender 1 includes a protective layer body 3 that covers at least the outer surface of the entire body portion 1a and the outer surface area that is half the total area of the mirror portion 1b on the radially outer side of each mirror portion 1b. The protective layer body 3 is integrated as a fender 1 by vulcanization adhesion. That is, the inner surface of the protective layer body 3 is tightly fixed with no gap between the opposing surface. The protective layer body 3 can be additionally vulcanized and bonded to the outer surface of the conventional fender 1A, or the protective layer body 3 can be vulcanized and bonded to the outer layer rubber of the conventional fender 1A.
　保護層体３としては、上述した種々の仕様を用いることができる。ただし、保護層体３のみが着脱できる仕様ではないので、保護層体３を交換することができない。そのため、保護層体３は耐油性部材により形成される。また、保護層体３は圧縮および復元変形に追従する必要があるので、ゴム等の弾性部材により形成されることが好ましい。 As the protective layer body 3, the various specifications described above can be used. However, since it is not the specification which only the protective layer body 3 can attach or detach, the protective layer body 3 cannot be replaced | exchanged. Therefore, the protective layer body 3 is formed of an oil resistant member. Moreover, since it is necessary for the protective layer body 3 to follow compression and decompression deformation, it is preferably formed of an elastic member such as rubber.
　防舷材１の使用方法は上述した実施形態と同様である。この防舷材１によれば、防舷材１の保護層体３により被覆された範囲は水面に浮遊する油Ｃと隔絶され、実質的に防舷材１に油Ｃが付着することを回避できる。それ故、水面に浮遊する油Ｃによる防舷材１の膨潤劣化を効果的に抑制できる。 The method of using the fender 1 is the same as in the above-described embodiment. According to the fender 1, the area covered by the protective layer 3 of the fender 1 is isolated from the oil C floating on the water surface, and the oil C is substantially prevented from adhering to the fender 1. it can. Therefore, the swelling deterioration of the fender 1 due to the oil C floating on the water surface can be effectively suppressed.
　この防舷材１では上述した取り付け部４が不要になるという利点、保護層体３がずれないという利点がある。 This fender 1 has the advantage that the mounting portion 4 described above is not necessary and the advantage that the protective layer body 3 does not shift.
　図５に例示した実施形態では、それぞれの鏡部１ｂの一部の外面は保護層体３により被覆されているが、保護層体３に被覆されずに露出している部分がある。そこで、図６に例示する防舷材１の実施形態では、保護層体３が、胴体部１ａ全体の外面およびそれぞれの鏡部１ｂ全体の外面を被覆する構成になっている。 In the embodiment illustrated in FIG. 5, a part of the outer surface of each mirror portion 1 b is covered with the protective layer body 3, but there is a portion exposed without being covered with the protective layer body 3. Therefore, in the embodiment of the fender 1 illustrated in FIG. 6, the protective layer body 3 is configured to cover the outer surface of the entire body portion 1a and the outer surface of the entire mirror portion 1b.
　この実施形態によれば、実質的に防舷材１の全体の外面が、保護層体３によって、水面に浮遊する油Ｃから隔絶されて保護される。これにより、防舷材１の膨潤劣化を抑制するには一段と有利になる。 According to this embodiment, substantially the entire outer surface of the fender 1 is isolated and protected from the oil C floating on the water surface by the protective layer body 3. Thereby, it becomes more advantageous to suppress the swelling deterioration of the fender 1.
