【考案の詳細な説明】
本考案は防舷材に関し、詳しくは、船舶の通常接舷時は
勿論、斜め接舷時における変形圧縮にも十分な耐久性を
有すると共に、接舷時における反力の急激な上昇を防止
できる筒状緩衝体型の防舷材に関するものである。[Detailed description of the invention] The present invention relates to a fender material, and more specifically, it has sufficient durability against deformation and compression not only when a ship comes alongside normally, but also when it comes alongside diagonally, and also has sufficient resistance to the reaction force when coming alongside. This invention relates to a cylindrical shock-absorbing fender that can prevent a sudden rise in water.
従来筒状緩衝体型の防舷材は、第１図に示す如く、ゴム

などの補強材１３ ａ 、１３ ｂを埋設した岸壁への
取り付は側のフランジ１２ ａ及び受衝板（図示しない
）への取り付は側フランジ１２ｂを、前記筒体１１の成
型時において一体的に形成した構造になっている。As shown in Fig. 1, conventional fenders of cylindrical shock-absorbing type are constructed of an elastic hollow cylindrical body 11 mainly made of rubber, with reinforcing materials 13a and 13b, such as metal, buried inside at both ends. The side flange 12a is attached to the cylindrical body 11, and the side flange 12b is attached to the impact plate (not shown), which are integrally formed when the cylindrical body 11 is molded.
一般に船舶が岸壁等に斜めに接舷した場合、岸壁に取り
付けられている防舷材は、その−側が圧縮され、他側が
引張り伸長され、いわゆる異常な変形圧縮を受ける。Generally, when a ship comes alongside a quay diagonally, the fender attached to the quay is compressed on its negative side and stretched in tension on the other side, undergoing so-called abnormal deformation and compression.
従って前述の如く緩衝体の主体をなす筒体１１に、一体
的にフランジ１２ ａ 、１２ ｂを突設したものは、
前記斜め接舷時に前記引張り伸長を受ける側の各フラン

ため、繰返し使用中この各付は根部１４にクラックが発
生したり、前記補強金物１３ ａ 、１３ ｂとの接着
部が破壊され、ついには使用できなくなる問題があった
。Therefore, as mentioned above, the cylindrical body 11 forming the main body of the shock absorber has the flanges 12 a and 12 b integrally protruding from it.
During the diagonal coming alongside, each flange portion on the side receiving the tensile extension is subjected to a large bending moment, and stress is concentrated on the root portion 14 of each of the flanges 12a and 12b. There was a problem in that cracks were generated in the reinforcing metal parts 14, and the bonded parts with the reinforcing metal parts 13a and 13b were destroyed, eventually rendering the reinforcing metal parts unusable.
そこで従来のこの問題の解決策として、前記フランジ１
２ ａ 、１２ ｂの各付は根部１４の肉厚を、特に厚
肉化するなどしてこれを補強する必要があり、この結果
重量の増加、コストアップ等別の問題が発生する一方、
従来のものは前述の如く、フランジを成型時において一
体的に成型するため、製造コストが高くなる。Therefore, as a conventional solution to this problem, the flange 1
2a and 12b, it is necessary to strengthen the root portion 14 by making it particularly thick, which results in other problems such as increased weight and cost.
As mentioned above, in the conventional type, the flange is integrally molded during molding, resulting in high manufacturing costs.

問題があるのが現状である。In addition, in the conventional fender described above, when the elastic hollow cylinder 11 is compressed and expanded in diameter when a ship comes alongside, the outer peripheral surface of the elastic hollow cylinder 11 is attached to the quay as shown in FIG. If it is attached to the side flange 12a, and if it is attached to the impact plate, it will come into contact with the side flange 12b, and the reaction force of the fender will increase rapidly, which may have a negative impact on the ships coming alongside. Otherwise, the outer circumferential surface of the elastic hollow cylinder 11 mentioned above comes into contact with the anchor pole l-8 and nut 9 for mounting on the quay, and the bolt 7 and nut 7' for mounting the impact plate, and is damaged. The current situation is that there are problems.
