Description

空気式防舷材およびその折り畳み方法Pneumatic fender and its folding method
　本発明は、空気式防舷材およびその折り畳み方法に関し、さらに詳しくは、防舷材を構成する袋体の内部の空気を円滑に外部に排出させ、収縮させて畳んだ状態にするために要する時間を短縮できる空気式防舷材およびその折り畳み方法に関するものである。 The present invention relates to a pneumatic fender and a folding method thereof. More specifically, the present invention is required to smoothly discharge the air inside the bag body constituting the fender to the outside in a contracted state. The present invention relates to a pneumatic fender capable of reducing time and a folding method thereof.
　空気式防舷材は一般的に、円筒状部の両端にボウル状の鏡部が連接された袋体を備えている。この防舷材を使用する場合には、袋体の内部に空気等を入れて膨張させた状態にする。一方、防舷材を使用しない状況、例えば、防舷材を製造した工場等で保管する場合や、搬送する場合には、袋体を膨張させた状態では嵩張るため、袋体の内部から空気を排出させることにより収縮させて折り畳んだ状態にする（例えば、特許文献１参照）。 空 気 Pneumatic fenders generally have a bag body in which a bowl-shaped mirror part is connected to both ends of a cylindrical part. When this fender is used, the bag is inflated with air or the like. On the other hand, when the fender is not used, for example, when it is stored in a factory where the fender is manufactured or transported, the bag body is inflated and is bulky. By discharging, it is contracted and folded (see, for example, Patent Document 1).
　一方の鏡部には、袋体の内部と外部とを連通させる排出口を備えた口金具が設けられている。袋体の内部から空気を外部に排出する際には、例えば、真空ポンプに接続された排気ホースを排出口に連結する。そして、真空ポンプを稼動することにより、排出口および排気ホースを通じて、袋体の内部から空気を外部に排出させることにより収縮させて折り畳んだ状態にしている。 One of the mirror parts is provided with a fitting having a discharge port for communicating the inside and the outside of the bag body. When discharging air from the inside of the bag body to the outside, for example, an exhaust hose connected to a vacuum pump is connected to the discharge port. Then, by operating the vacuum pump, air is discharged from the inside of the bag body to the outside through the discharge port and the exhaust hose so as to be contracted and folded.
　空気を外部に排出するに連れて袋体が収縮するが、袋体がある程度収縮した状態になると、排出口が袋体の対向する内面に当接して塞がれることがある。排出口が塞がれると、袋体の内部から空気を排出することができなくなる。このような場合には、排出口から空気を袋体の内部に注入して袋体を若干膨張させて、排出口を袋体の内面から離反させる。次いで、排出口が袋体の内面に当接して塞がれないように注意しながら、再度、袋体の内部から空気を排出させて収縮させている。 The bag body shrinks as the air is discharged to the outside, but when the bag body is contracted to some extent, the discharge port may be in contact with the opposing inner surface of the bag body to be blocked. When the discharge port is blocked, air cannot be discharged from the inside of the bag. In such a case, air is injected into the bag body from the discharge port to slightly expand the bag body, and the discharge port is separated from the inner surface of the bag body. Next, air is discharged again from the inside of the bag body and contracted, taking care that the discharge port is not in contact with the inner surface of the bag body and blocked.
　このように、ある程度空気を外部に排出させた袋体に対して、空気を内部に注入して若干膨張させた後に再度、袋体の内部から空気を外部に排出させる作業が必要になるため、作業工数が増加する。これに伴い、袋体を収縮させて折り畳んだ状態にするために要する時間が長くなるという問題がある。 In this way, for the bag body from which air has been discharged to the outside to some extent, after injecting air into the interior and slightly inflating, it is necessary to work to discharge air from the inside of the bag body to the outside again. Work man-hours increase. Along with this, there is a problem that it takes a long time to shrink the bag body into a folded state.

　本発明の目的は、防舷材を構成する袋体の内部の空気を円滑に外部に排出させて、収縮させて畳んだ状態にするために要する時間を短縮できる空気式防舷材およびその折り畳み方法を提供することにある。 An object of the present invention is to provide a pneumatic fender capable of reducing the time required to smoothly deflate and fold the air inside the bag constituting the fender, and to fold the pouch. It is to provide a method.
　上記目的を達成するため本発明の空気式防舷材は、円筒状部の両端にボウル状の鏡部を連接した袋体と、前記袋体の内部と外気とを連通させる排出口を有して前記鏡部の一方に埋設されている口金具とを備えた空気式防舷材において、前記口金具が埋設されている範囲の前記袋体の内面に、前記袋体の内側に向かって突出する突部を有し、前記袋体を収縮させた状態で前記突部が前記袋体の前記突部に対向した位置にある内面に当接することにより、前記口金具が埋設されている範囲の前記袋体の内面と、前記突部が当接した側の前記袋体の内面との間にすき間が存在するとともに、このすき間が前記排出口に連通した状態になる構成にしたことを特徴とする。 In order to achieve the above object, a pneumatic fender according to the present invention has a bag body in which a bowl-shaped mirror part is connected to both ends of a cylindrical part, and a discharge port that allows the inside of the bag body to communicate with outside air. A pneumatic fender having a fitting that is embedded in one of the mirror portions, and protrudes toward the inside of the bag body on the inner surface of the bag body in a range where the fitting is embedded. In a range in which the fitting is embedded by contacting the inner surface of the bag body at a position facing the projection in the contracted state of the bag body. A gap exists between the inner surface of the bag body and the inner surface of the bag body on the side on which the protrusion abuts, and the gap communicates with the discharge port. To do.
　本発明の空気式防舷材の折り畳み方法は、円筒状部の両端にボウル状の鏡部を連接した袋体と、前記袋体の内部と外気とを連通させる排出口を有して前記鏡部の一方に埋設されている口金具とを備えた空気式防舷材を、前記袋体の内部から空気を排出させることにより収縮させて、前記鏡部のそれぞれを前記円筒状部の上側にして平坦状に折り畳んだ状態にする空気式防舷材の折り畳み方法において、
　前記口金具が埋設されている範囲の前記袋体の内面に、前記袋体の内側に向かって突出する突部を設けておき、前記排出口から前記袋体の内部の空気を外部に排出させて前記袋体を収縮させることにより、前記突部を前記袋体の前記突部に対向する位置にある内面に当接させて、前記口金具が埋設されている範囲の前記袋体の内面と、前記突部が当接した側の前記袋体の内面との間にすき間を形成するとともに、このすき間を前記排出口に連通させた状態にして、この状態で前記排出口から前記袋体の内部の空気を外部に排出させて収縮させることにより、前記鏡部のそれぞれを前記円筒状部の上側にして平坦状に折り畳んだ状態にすることを特徴とする。 The method of folding a pneumatic fender according to the present invention includes a bag body in which a bowl-shaped mirror portion is connected to both ends of a cylindrical portion, and a discharge port that allows the inside of the bag body to communicate with outside air. A pneumatic fender having a mouth fitting embedded in one of the parts is contracted by discharging air from the inside of the bag body so that each of the mirror parts is placed above the cylindrical part. In the method of folding a pneumatic fender that is folded into a flat shape,
A protrusion projecting toward the inside of the bag body is provided on the inner surface of the bag body in a range where the fitting is embedded, and the air inside the bag body is discharged to the outside from the discharge port. By contracting the bag body, the projecting portion is brought into contact with the inner surface of the bag body at a position facing the projecting portion, and the inner surface of the bag body in a range in which the fitting is embedded. In addition, a gap is formed between the inner surface of the bag body on the side on which the protrusion abuts, and the gap is communicated with the discharge port. The inside air is exhausted to the outside and contracted, so that each of the mirror portions is placed on the upper side of the cylindrical portion to be folded flat.
　本発明によれば、前記排出口から前記袋体の内部の空気を外部に排出させて前記袋体を収縮させた際に、前記突部が前記袋体の前記突部に対向する位置にある内面に当接して前記口金具が埋設されている範囲の前記袋体の内面と、前記突部が当接した側の前記袋体の内面との間にすき間が形成される。また、このすき間は前記排出口に連通させた状態になる。そのため、袋体が収縮しても排出口が袋体の対向する内面に当接して塞がれることがなく、空気排出のためのすき間を確保できる。したがって、袋体の内部の空気を円滑に外部に排出させて収縮させることにより、短時間で、前記鏡部のそれぞれを前記円筒状部の上側にして平坦状に折り畳んだ状態にすることが可能になる。 According to the present invention, when the air inside the bag body is discharged to the outside from the discharge port and the bag body is contracted, the protrusion is in a position facing the protrusion of the bag body. A gap is formed between the inner surface of the bag body that is in contact with the inner surface and in which the cap fitting is embedded, and the inner surface of the bag body on the side that the protrusion contacts. Further, the gap is in a state of communicating with the discharge port. Therefore, even if the bag body contracts, the discharge port does not come into contact with the opposing inner surface of the bag body and is not blocked, and a gap for air discharge can be secured. Therefore, by smoothly discharging the air inside the bag body to the outside and contracting it, it is possible to fold the mirror part flatly with each of the mirror parts above the cylindrical part in a short time. become.
　ここで、前記突部が弾性部材により形成されている仕様にすることも、前記口金具が内側表面に金具突起部を有し、この金具突起部によって前記突部が形成された状態になっている仕様にすることもできる。 Here, the specification that the protrusion is formed of an elastic member also means that the metal fitting has a metal protrusion on the inner surface, and the protrusion is formed by the metal protrusion. It is possible to make it a specification.
　前記突部が、前記排出口の近傍から、前記口金具が埋設されている前記鏡部の半径方向外側に向かって延在している仕様にすることもできる。この仕様によれば、空気を排出すき間を確保し易くなる。さらに、前記突部が複数であり、前記排出口を中心にして放射状に延在している仕様にすることもできる。この仕様によれば、袋体が、円筒状部の周方向のどのような位置で置かれた状態であっても、円滑に袋体の内部から空気を排出させることができる。 The specifications may be such that the protruding portion extends from the vicinity of the discharge port toward the radially outer side of the mirror portion in which the fitting is embedded. According to this specification, it becomes easy to secure a gap for discharging air. Furthermore, it can also be set as the specification which has the said several protrusion, and has extended radially centering on the said discharge port. According to this specification, air can be smoothly discharged from the inside of the bag body, regardless of the position of the bag body in the circumferential direction of the cylindrical portion.
　或いは、前記突部が複数の点状体であり、これら点状体の突部が散在している仕様にすることもできる。この仕様によっても、体が、円筒状部の周方向のどのような位置で置かれた状態であっても、円滑に袋体の内部から空気を排出させることができる。 Alternatively, the projection may be a plurality of dot-like bodies, and the specifications may be such that the projections of these dot-like bodies are scattered. According to this specification, air can be smoothly discharged from the inside of the bag body regardless of the position of the body in the circumferential direction of the cylindrical portion.

Necessary parts such as an opening / closing valve and a safety valve for opening and closing the discharge port are appropriately provided in the fitting 6. The discharge port 8 has a function of communicating the inside of the bag body 2 with the outside (outside air) and discharging the air a inside the bag body 2 to the outside. The discharge port 8 of this embodiment also functions as an injection port for injecting air a from the outside to the inside of the bag body 2.
　口金具６が埋設されている範囲の袋体２の内面には、袋体２の内側に向かって突出する突部５が備わっている。この実施形態では、突部５が排出口８の近傍（例えば、排出口８から３０ｍｍ以上１００ｍｍ以下程度の位置）から、口金具６が埋設されている鏡部４の半径方向外側に向かって延在している。具体的には、平板部７の範囲内に突部５が延在している。尚、突部５は平板部７の外縁よりも鏡部４の半径方向外側に向かって延在させることもできる。 The inner surface of the bag body 2 in the range where the metal fitting 6 is embedded is provided with a protrusion 5 that protrudes toward the inner side of the bag body 2. In this embodiment, the protrusion 5 extends from the vicinity of the discharge port 8 (for example, a position about 30 mm or more and 100 mm or less from the discharge port 8) toward the radially outer side of the mirror unit 4 in which the fitting 6 is embedded. Exist. Specifically, the protrusion 5 extends within the range of the flat plate portion 7. Note that the protrusion 5 can also extend from the outer edge of the flat plate portion 7 toward the radially outer side of the mirror portion 4.
　突部５の大きさは例えば、延在長さが５０ｍｍ以上１５０ｍｍ以下、幅が５ｍｍ以上１５ｍｍ以下、袋体２の内面からの突出高さが５ｍｍ以上１５ｍｍ以下である。ただし、突部５の大きさはこれに限定されることはなく、後述するすき間を確保できる大きさであればよい。 The size of the protrusion 5 is, for example, an extension length of 50 mm to 150 mm, a width of 5 mm to 15 mm, and a protrusion height from the inner surface of the bag body 2 of 5 mm to 15 mm. However, the magnitude | size of the protrusion 5 is not limited to this, What is necessary is just a magnitude | size which can ensure the clearance gap mentioned later.
　突部５は単数にすることもできるが、複数にすることが好ましい。そして、この実施形態のように、排出口８を中心にして複数の突部５を放射状に延在させるとよい。例えば、突部５の数は３本～１６本程度、さらに好ましくは４本～８本にして、周方向に等間隔に配置して放射状に延在させる。 The protrusion 5 can be singular but is preferably plural. And like this embodiment, it is good to extend the some protrusion 5 radially centering on the discharge port 8. FIG. For example, the number of the protrusions 5 is about 3 to 16, more preferably 4 to 8, and they are arranged at equal intervals in the circumferential direction and extend radially.
　突部５は例えば、ゴム等の弾性部材により形成される。具体的には、ゴム片を接着剤等の適宜の接合手段によって袋体２の内面に接合する。突部５は、袋体２の内部から外部へ空気ａを排出する時だけに用いるので、恒久的な接合強度は不要であり、突部５と袋体２の内面との接合強度は低くても構わない。 The protrusion 5 is formed of an elastic member such as rubber, for example. Specifically, the rubber piece is bonded to the inner surface of the bag body 2 by an appropriate bonding means such as an adhesive. Since the protrusion 5 is used only when the air a is discharged from the inside of the bag body 2 to the outside, no permanent bonding strength is required, and the bonding strength between the protrusion 5 and the inner surface of the bag body 2 is low. It doesn't matter.
　次に、本発明の防舷材の折り畳み方法により、この防舷材１の袋体２を収縮させて平坦状に折り畳む手順の一例を説明する。 Next, an example of a procedure for shrinking the bag 2 of the fender 1 and folding it into a flat shape by the method of folding the fender according to the present invention will be described.
　工場で防舷材１を製造した後、特別な内圧を付与することなく膨張している袋体２を図３、図４に例示するように横倒し状態にして、排出口８に排出ホース１０の一端部を接続する。排出ホース１０の他端部には真空ポンプ９を接続する。 After the fender 1 is manufactured at the factory, the bag body 2 that is inflated without applying a special internal pressure is laid down as illustrated in FIGS. 3 and 4, and the discharge hose 10 is connected to the discharge port 8. Connect one end. A vacuum pump 9 is connected to the other end of the discharge hose 10.
　次いで、真空ポンプ９を稼動させて排出口８および排出ホース１０を通じて、袋体２の内部の空気ａを外部に排出させる。これにより、袋体２は徐々に収縮する。袋体２がある程度収縮した状態になると、突部５が袋体２の突部５に対向する位置にある内面に当接する。そして、突部５が対向する袋体２の内面に当接することで、口金具６（平板部７）が埋設されている範囲の袋体２の内面と、突部５が当接した側の袋体２の内面との間にすき間が形成される。このすき間は、排出口５に連通した状態になる。 Next, the vacuum pump 9 is operated, and the air a inside the bag body 2 is discharged to the outside through the discharge port 8 and the discharge hose 10. Thereby, the bag body 2 contracts gradually. When the bag body 2 is contracted to some extent, the protrusion 5 comes into contact with the inner surface at a position facing the protrusion 5 of the bag body 2. And the protrusion 5 contacts the inner surface of the opposite bag body 2, so that the inner surface of the bag body 2 in the range in which the fitting 6 (flat plate portion 7) is embedded, and the side where the protrusion 5 contacts. A gap is formed between the inner surface of the bag body 2. This gap is in a state of communicating with the discharge port 5.
　袋体２の内部に、このようなすき間が延在するため、引き続いて真空ポンプを稼動させても、すき間と排出口８と排出ホース１０を通じて、袋体２の内部の空気ａを外部に排出させることができる。袋体２をさらに収縮させてもすき間は確保される。 Since such a gap extends inside the bag body 2, the air a inside the bag body 2 is discharged to the outside through the gap, the discharge port 8 and the discharge hose 10 even if the vacuum pump is subsequently operated. Can be made. Even if the bag body 2 is further contracted, the clearance is secured.
　図７に例示するように、突部５を有していない従来の空気式防舷材１１では、袋体２がある程度収縮した状態になると、排出口８が袋体２の対向する内面に当接して塞がれることがあり、袋体２の内部から空気ａを排出することができなくなる。本発明では、突部５を設けることで、このような不具合の発生を回避している。 As illustrated in FIG. 7, in the conventional pneumatic fender 11 that does not have the protrusion 5, when the bag body 2 is contracted to some extent, the discharge port 8 contacts the opposing inner surface of the bag body 2. The air a may not be discharged from the inside of the bag body 2 in some cases. In the present invention, the occurrence of such a problem is avoided by providing the protrusion 5.
　本発明の防舷材１では、図３、図４に例示するように、内部の空気ａがほとんど外部に排出されて袋体２が収縮して、それぞれの鏡部４が円筒状部３の上側にして平坦状に折り畳んだ状態になっても、排出口８が袋体２の対向する内面に当接して塞がれることがなく、すき間が確保される。それ故、袋体２の内部の空気ａを円滑に外部に排出させることで収縮させて、平坦状に折り畳むために要する時間を短縮することが可能になる。 In the fender 1 of the present invention, as illustrated in FIG. 3 and FIG. 4, the air a inside is almost exhausted to the outside and the bag body 2 is contracted, and each mirror part 4 is a cylindrical part 3. Even if the upper side is folded in a flat shape, the discharge port 8 does not abut against the facing inner surface of the bag body 2 and is not blocked, and a clearance is secured. Therefore, it is possible to shorten the time required to fold the bag 2 into a flat shape by causing the air a inside the bag body 2 to be smoothly discharged and contracted.
　このように平坦状に折り畳まれた袋体２は、その後、必要に応じて、円筒状部３の筒軸方向の折り目に沿って、適宜、２つ折りや３つ折りにされる。 The bag body 2 folded in such a flat shape is then appropriately folded in two or three along the folds in the cylindrical axis direction of the cylindrical portion 3 as necessary.
　この実施形態のように、突部５が排出口８の近傍から、鏡部４の半径方向外側に向かって延在していると、すき間の延在長さが長くなる。これにより、空気ａを袋体２の内部に残留させずに外部に排出させ易くなる。 As in this embodiment, when the protrusion 5 extends from the vicinity of the discharge port 8 toward the outer side in the radial direction of the mirror part 4, the extension length of the gap becomes long. Thereby, it becomes easy to discharge the air a outside without remaining inside the bag body 2.
　複数の突部５が排出口８を中心にして放射状に延在していると、袋体２が、円筒状部３の周方向のどのような位置で横倒しで置かれた状態であっても、すき間を確保し易くなるため、円滑に袋体２の内部から空気ａを排出させるには有利になる。 If the plurality of protrusions 5 extend radially around the discharge port 8, the bag body 2 is in a state where it is placed on its side at any position in the circumferential direction of the cylindrical portion 3. Since it becomes easy to secure the gap, it is advantageous for smoothly discharging the air a from the inside of the bag body 2.
　図５に例示するように、平板部７の内側表面に袋体２の内側に突出する金具突起部７ａを設けることもできる。そして、この平板部７を袋体２に埋設した状態にすることで、金具突起部７ａに相当する部分が袋体２の内側に突出する。この金具突起部７によって袋体２の内側に突出した部分を、突部５として機能させることもできる。この仕様の場合は、突部５にする部材をわざわざ用意して袋体２の内面に接合する必要がない。 As illustrated in FIG. 5, a metal projection 7 a that protrudes inside the bag body 2 can be provided on the inner surface of the flat plate portion 7. Then, by setting the flat plate portion 7 to be embedded in the bag body 2, a portion corresponding to the metal projection 7 a protrudes inside the bag body 2. A portion that protrudes inside the bag body 2 by the metal protrusion 7 can also function as the protrusion 5. In the case of this specification, it is not necessary to prepare a member to be the protrusion 5 and join it to the inner surface of the bag body 2.
　突部５は、上述したすき間を確保できれば、図６に例示するように、複数の点状体にすることもできる。点状体の突部５は、口金具６が埋設されている範囲の袋体２の内面に万遍なく散在させるとよい。このような突部５にすることによっても、袋体２が、円筒状部３の周方向のどのような位置で横倒しで置かれた状態であっても、すき間を確保し易くなるため、円滑に袋体２の内部から空気ａを排出させるには有利になる。 The protrusion 5 can be formed into a plurality of dot-like bodies as illustrated in FIG. 6 as long as the above-described gap can be secured. It is preferable that the protrusions 5 of the dot-like body are uniformly distributed on the inner surface of the bag body 2 in the range where the fitting 6 is embedded. Even with such a protrusion 5, it is easy to secure a gap even when the bag body 2 is placed on its side at any position in the circumferential direction of the cylindrical portion 3. It is advantageous to exhaust air a from the inside of the bag body 2.
