Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a fender that is attached to a quay and used as a cushioning material when a ship is docked.

[0002]

[Prior Art]

 The fender is formed of a rubber base material, and is manufactured by heating and vulcanizing the rubber base material using a mold. As the material of the rubber base material used for the fender, natural rubber, synthetic rubber such as butadiene and styrene-butadiene, or a blend rubber thereof is used.

The main color of the appearance of the fender is black. This is because carbon black is added as a rubber reinforcing agent in order to ensure abrasion resistance and damage resistance of the fender because it repeatedly contacts the side of the ship. There are also color fenders, which are used for the aesthetics of the harbor and to prevent black stains on the vessels calling. Colored fenders use colored rubber reinforcements other than carbon black. As a rubber reinforcing agent for a color fender, silica containing a silane coupling agent is used.

[0004]

[Problems to be solved by the device]

 However, fenders with a black exterior color are difficult to distinguish from the quay, so the berthing speed of the ship sometimes becomes excessive, which may cause damage to the quay and the ship itself, leading to a lack of safety. there were. Since color fenders are inferior in strength to black fenders that use carbon black as a rubber reinforcing agent, there is a problem that they are immediately damaged during repeated contact with a ship.

In addition, since it is very difficult to identify both black fenders and color fenders at night, the berthing speed is too high and the berths and ships are damaged, resulting in poor safety. There was a problem. The purpose of this invention is to ensure the same durability as the black fender and to make it easy to distinguish it from the quay, so that it is possible to ensure safety when the ship is docked, and even at night. It is to provide a fender that can be distinguished from the quay.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the structure of the fender of the present invention is a fender in which carbon black as a rubber reinforcing agent is mixed with a rubber base material, and a color stripe pattern is provided on the side visible from a ship. It is characterized by being attached. Further, as the fender, a large number of transparent fine particles may be arranged in the color stripe pattern portion.

[0007]

[Action]

 According to the above configuration, since the color stripe pattern is attached to the side visible from the ship, it can be easily distinguished from the quay when berthing. Also, when a large number of transparent fine particles are arranged in the color stripe pattern of the fender, the light from the ship is diffusely reflected by the transparent fine particles even at night, making it easier to distinguish from the quay when berthing. Can be

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a plan view showing a fender according to an embodiment of the present invention, and FIG. 2 is a perspective view of the fender shown in FIG. With reference to these drawings, the fender has an impact receiving part 4 that comes into contact with the port side when the ship is berthed, a side wall part 5 extending in a divergent manner from the impact receiving part 4, and a side wall part 5 of the side wall part 5. It is a so-called V-shaped fender, which is provided with a mounting portion 6 provided at each tip. When the port side comes into contact with the impact receiving portion 4, the side wall portion 5 can be bent and deformed to absorb the impact at the time of berthing. Although not shown, the mounting portion 6 is embedded with iron plates, and mounting holes 61 are provided near both ends of the mounting portion 6 so that the fender can be fixed to the quay by using known fixing means such as bolts. ing. The impact receiving portion 4, the side wall portion 5, and the mounting portion 6 are black in which carbon black is mixed with a rubber base material.

On the surfaces of the impact receiving portion 4 and the side wall portion 5, a plurality of color stripes 1 of orange, yellow, red, etc. are attached in parallel. The color stripe 1 is made by attaching a rubber sheet for a color stripe 1 of a desired color such as orange to a black rubber sheet containing carbon black and covering the impact receiving portion 4 and the side wall portion 5. It is formed by pasting. A large number of colorless glass beads 3 as transparent fine particles are embedded in one part of each color stripe. Note that the hardness of the main body is 65 to 72 ° in JIS A hardness, and the hardness of the rubber sheet for color stripe 1 is JIS A so that the fender main body receives an impact when the ship contacts. The hardness is set to around 50 °. As a result, the color stripe 1 portion can be easily compressed when the ship comes into contact with the glass beads 3, so that the glass beads 3 are less likely to be damaged.

Since the fender of the above-mentioned embodiment having the above-mentioned configuration contains carbon black, durability can be ensured, and on the side of the impact receiving portion 4 and the side wall portion 5 which is visible from the ship, Since the color stripe 1 is attached, it can be easily distinguished from the quay as seen from the ship. Therefore, it is possible to ensure the safety at the time of berthing. In addition, since the glass beads 3 are arranged in the color stripe 1 part, lights from the ship are diffusely reflected by the glass beads 3 even at night, which makes it easier to distinguish from the quay when berthing. Therefore, it is possible to ensure safety even when docking at night.

The shape of the fender in the above embodiment is not limited to the V shape, but may be various shapes such as a rectangular shape, a trapezoidal shape, and a half-column shape. The color stripe 1 may be embedded by forming grooves on the surfaces of the impact receiving portion 4 and the side wall portion 5. In this case, the glass beads 3 do not protrude from the surface of the impact receiving portion 4 and the side wall portion 5. It may be attached to the surface of the color stripe 1 within a range. The color of the color stripe 1 can be freely selected by combining one color or multicolors.

Further, although the glass beads 3 are colorless and transparent, colored transparent beads may be used. The glass beads 3 are not limited to spherical shapes, but may have various shapes, and transparent fine particles such as transparent plastics may be used. Of course, it can be carried out without disposing the glass beads 3.

Furthermore, in order to further improve the durability of the fender, a polyurethane elastomer coating layer may be provided on the surface of the impact receiving portion 4, the side wall portion 5, and the like. Further, as the black rubber composition of the fender body, a non-contaminating raw material may be adopted, and in this case, the color stripe 1 can be prevented from being contaminated. Also, by using a rubber that uses this non-staining raw material for the surface of the black rubber, it is possible to prevent the color stripe 1 from being contaminated by the black rubber of the fender body. It is possible to make various design changes within the range that does not change.

[Effect of the device]

 As described above, according to the fender of the present invention, since the color stripe pattern is provided, it is possible to easily distinguish the ship from the quay and ensure the safety when berthing. Further, when the transparent fine particles are arranged in the color stripe pattern, it is easy to distinguish from the quay even at night, and the safety can be secured even at the time of berthing at night.

Furthermore, since the rubber base material is blended with carbon black as a rubber reinforcing material, a material having excellent durability can be obtained.
