【発明の属する技術分野】
この発明は空気式防舷材に係わり、更に詳しくは防舷材本体の長手方向両側における鏡部の質量が同等になるように構成した空気式防舷材に関するものである。
【０００２】
【従来の技術】
従来、長楕円形状に形成して成る空気式防舷材には、防舷材本体の両方の鏡部にマンホール（作業員等の出入り出来る穴）を形成すると共に、このマンホールを塞ぐための口金を設けた空気式防舷材と、防舷材本体の片側の鏡部にマンホールを形成すると共に、このマンホールを塞ぐための口金を設けた空気式防舷材とが知られている。
【０００３】
【発明が解決しようとする課題】
然しながら、防舷材本体の両方の鏡部にマンホール及び口金を設けた空気式防舷材の場合には、マンホールを塞ぐ口金及び口金を取付けるための部材が二組必要となるため、部品費が高くなると共に、取付け作業も多くなると言う問題があった。また、マンホールを設けるための加工や、口金取付け部材の取付け加工、マンホールを設けるために必要となる鏡部の補強加工が両側で必要となるため加工費用が高くなると言う問題があった。
【０００４】
また、防舷材本体の片側の鏡部にマンホール及び口金を設けた空気式防舷材の場合には、マンホールを設けるための部品費及び加工費が約半分となるが、口金及び口金取付け部材の質量で左右の質量バランスを失い、防舷材本体を水上に浮かべた際、防舷材本体を水平に保つことが出来ないと言う問題があった。
【０００５】
この発明の目的は、片側の鏡部のみにマンホールを形成した空気式防舷材の長手方向両側の鏡部における質量を同等になるように構成して、海上浮遊時における長手方向の水平性を確保すると共に、構成が簡単で安価に製造することが出来る空気式防舷材を提供することにある。
【０００６】
【課題を解決するための手段】
この発明は上記目的を達成するため、長楕円形状に形成して成る防舷材本体の一方の鏡部のみにマンホールを形成し、該マンホールに口金取付け金具を介して少なくとも一種類以上のバルブを取付けた口金を設けた空気式防舷材において、前記防舷材本体のマンホールを形成していない他方の鏡部に、錘取付け金具を介して互いに分離可能に独立した複数の錘を取付けると共に、該錘の分離着脱により両鏡部における総質量を、前記防舷材本体を水上に浮かべた時に水平になるように設定可能にしたことを要旨とするものである。
【０００７】
上述する構成において、前記複数の錘を防舷材本体内に突出した前記錘取付け金具に螺嵌して分離可能に固定するとよい。さらに、前記複数の錘を円板状に形成するとよい。
【０００８】
このように、防舷材本体の一方の鏡部のみに、口金取付け金具を介して少なくとも一種類以上のバルブを取付けた口金を設けた空気式防舷材において、前記防舷材本体のマンホールを形成していない他方の鏡部に、錘取付け金具を介して互いに分離可能に独立した複数の錘を取付けると共に、該錘の分離着脱により両鏡部における総質量を、前記防舷材本体を水上に浮かべた時に水平になるように設定可能にしたことにより、海上浮遊時における長手方向の水平性を確保すると共に、構成が簡単で安価に製造することが出来るものである。
【０００９】
【発明の実施の形態】
以下、添付図面に基づき、この発明の実施形態を説明する。
【００１０】
図１は、この発明を実施した空気式防舷材の正面図、図２は図１のＡ部の拡大断面図、図３は図１のＢ部の拡大断面図を示し、長楕円形状に形成された防舷材本体１は、直胴部１ａと、直胴部１ａの両側の鏡部２ａ，２ｂとで筒状の密閉袋体に構成され、構成材料としては、金属コードまたは繊維コード等の補強材９ａと補強材９ａを覆うゴム等の可撓性材料９ｂとで構成されている。
【００１１】
前記防舷材本体１の一方の鏡部２ａには、図２に示すように、マンホール３に口金取付け金具４を介して口金５を取付け、この口金５には、エアーバルブ６及び安全弁７等の少なくとも一種類以上のバルブを取付けてある。
【００１２】
なお、前記口金取付け金具４の近傍に設けたビード８には、防舷材本体１内に埋設される前記補強材９ａが掛回されている。また、１０は、口金取付け金具４にボルト等の締結部材１１を介して取付けられたカバープレートを示している。
【００１３】
また、前記防舷材本体１の他方の鏡部２ｂには、図３に示すように、ネジ１２ａを設けた筒状体１２と、この筒状体１２の一端に一体的に形成された固定プレート１３とから成る錘取付け金具１４が埋設され、この錘取付け金具１４の防舷材本体１内に突出した筒状体１２のネジ１２ａには、円板状の錘１５が螺嵌されて固定してある。また、８は筒状体１２の近傍に固定されたビード、９ａは補強材であり、一方の鏡部２ａと同様な構成である。
【００１４】
なお、円板状の錘１５は、質量調整のために図に示すように、複数に分割して構成することが望ましい。また、ビード８と錘取付け金具１４と錘１５等からなる他方の鏡部２ｂの総質量は、防舷材本体１の一方の鏡部２ａの質量、即ち、口金取付け金具４，口金５及びエアーバルブ６，安全弁７等の総質量と略同じにすることで、防舷材本体１を水上に浮かべた時に水平になるものである。
【００１５】
このように、防舷材本体１の一方の鏡部２ａに、口金取付け金具４を介して少なくとも一種類以上のバルブを取付けた口金５を備えたマンホールを形成し、他方の鏡部２ｂに、錘取付け金具１４を介して互いに分離可能に独立した複数の錘１５を取付け、この錘の分離着脱により両鏡部２ａ、２ｂにおける総質量を、防舷材本体１を水上に浮かべた時に左右質量がバランスして水平状態となるように設定可能にすることにより、海洋浮遊時における長手方向の水平性を確保することができ、また構成が簡単であることから安価に製造することも可能である。
【００１６】
【発明の効果】
この発明は上記のように、長楕円形状に形成して成る防舷材本体の一方の鏡部のみにマンホールを形成し、このマンホールに口金取付け金具を介して少なくとも一種類以上のバルブを取付けた口金を設けた空気式防舷材において、防舷材本体のマンホールを形成していない他方の鏡部に、錘取付け金具を介して互いに分離可能に独立した複数の錘を取付けると共に、この錘の分離着脱により両鏡部における総質量を、防舷材本体を水上に浮かべた時に水平になるように設定可能にしたので、以下のような優れた効果を奏するものである。
(a).マンホールを形成していない側の鏡部に取付ける錘の分離着脱により両鏡部における質量バランスを調整するようにしたので、マンホールの質量に応じたバランス調整を可能にして、海洋浮遊時における水平性を確保することができる。
(b).防舷材本体の一方の鏡部にのみマンホールを形成し、このマンホールに口金取付け金具を介して少なくとも一種類以上のバルブを取付けた口金を取付けるように構成したので、構成が簡単になり、加工費も安く、安価に製造出来る。
(c).マンホールの無い他方の鏡部は、穴による欠損部がなく、ビードの外径も小さいので、強度上構造の簡略化が可能であり、従って補強材の配列構造が簡単となり、配列数も少ないので、防舷材本体の加工コストを低減させることが可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a pneumatic fender, and more particularly to a pneumatic fender constructed so that the masses of mirror parts on both sides in the longitudinal direction of the fender main body are equal.
[0002]
[Prior art]
Conventionally, pneumatic fenders formed in an elliptical shape have manholes (holes that allow workers to enter and exit) in both mirror parts of the fender body, and caps for closing the manholes. And a pneumatic fender having a base for closing the manhole while forming a manhole in a mirror portion on one side of the fender main body.
[0003]
[Problems to be solved by the invention]
However, in the case of a pneumatic fender that has manholes and bases on both mirror parts of the fender body, two sets of members are needed to attach the base and base to close the manholes, so the parts cost is high. There was a problem that the mounting work was increased as the cost increased. In addition, there is a problem that the processing cost is high because the processing for providing the manhole, the mounting processing of the base mounting member, and the mirror processing necessary for providing the manhole are required on both sides.
[0004]
In addition, in the case of a pneumatic fender with a manhole and a base provided on the mirror part on one side of the fender body, the parts cost and processing cost for providing the manhole are about half, but the base and the base attachment member When the weight balance of the left and right was lost, and the fender body was floated on the water, the fender body could not be kept horizontal.
[0005]
The object of the present invention is to configure the pneumatic fenders having manholes only on one side of the mirror part so that the masses at the mirror parts on both sides in the longitudinal direction are equal to each other, thereby improving the horizontality in the longitudinal direction when floating on the sea. while securing is to provide a pneumatic fender that can be manufactured at a low cost construction is simple.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention forms a manhole only in one mirror part of a fender body formed in an elliptical shape , and at least one type of valve is provided in the manhole via a base fitting. in the attached pneumatic fender having a mouthpiece, said the other of the mirror unit manhole no formation of fender body, mounting a plurality of weights which were separable independent of each other through the weight mounting bracket Rutotomoni The gist is that the total mass of both mirror parts can be set to be horizontal when the fender body is floated on water by separating and attaching the weight .
[0007]
In the above-described configuration, the plurality of weights may be fixed to the weight mounting bracket protruding into the fender main body by being threadably fitted. Furthermore, the plurality of weights may be formed in a disc shape.
[0008]
Thus, only one of the mirror portion of the fender main body, the pneumatic fender having a mouthpiece attached at least one or more of the valves through a die mounting bracket, the manhole of the fender body the other of the mirror portion is not formed, Rutotomoni mounting a plurality of weights which were separable independent of each other through the weight mounting brackets, the total mass in both mirrors portion by detachable of該錘, the fender main body Since it can be set to be horizontal when it floats on the water, it is possible to ensure the horizontality in the longitudinal direction when floating on the sea , and the structure is simple and inexpensive to manufacture.

【The invention's effect】
In the present invention, as described above , a manhole is formed only in one mirror portion of the fender body formed in an elliptical shape, and at least one type of valve is attached to the manhole via a base fitting. in pneumatic fender having a mouthpiece, the other mirror portion not forming a manhole fender body, mounting a plurality of weights which were separable independent of each other through the weight mounting bracket Rutotomoni, this weight Since the total mass of both mirror parts can be set to be horizontal when the fender body is floated on the water by separating and attaching , the following excellent effects can be obtained.
(a) Since the mass balance in both mirror parts is adjusted by separating and attaching the weight attached to the mirror part on the side where the manhole is not formed, it is possible to adjust the balance according to the mass of the manhole and It is possible to ensure levelness in time.
(b) A manhole is formed only on one mirror part of the fender body, and a base with at least one type of valve is attached to the manhole via a base mounting bracket. Therefore, the processing cost is low and it can be manufactured at low cost.
(c) The other mirror part without a manhole has no defect due to the hole and the outer diameter of the bead is small, so that the structure can be simplified in terms of strength, and therefore the reinforcing member arrangement structure becomes simple and the arrangement Since the number is small, the processing cost of the fender body can be reduced.
