  • Patent number: 8152581
    Abstract: Provided is a floater for marine hose, which can be easily formed into an annular shape conformable even to marine hoses having variations in the circularity of their cross-section or to marine hoses of different outside diameters. A belt-like floater 1 is formed by rotatably connecting together, by using connection pins 7a, float blocks 2 equal to the number corresponding to the outside diameter of a marine hose 10. A fitting groove is formed on the inner side of the belt-like floater 1. The groove is placed along the outer surface of the marine hose 10 while being fitted onto a location collar 11 projected on the outer surface of the marine hose 10. Then, the end portions of the floater are coupled together by an end coupling member 7b. Thus, the floater 1 is fitted in annular shape onto the marine hose 10.
