Abstract

PURPOSE:To prevent the damage in outside boards and, at the same time, to promote durability by coating the outside of a main body with a buffer reinforced material 10 of a friction resin having friction factor smaller than that of the main body, and reducing frictional resistance of the outside of the main body. CONSTITUTION:For example, urethane rubber is used to form a main body 6 of a projected or a semi-cylindrical fender 5. The outside of the main body or at least of the front end of the projection is coated with a buffer reinforced material 10 of low friction resin. For example, the top 6a of the main body 6 is coated by baking teflon resin having friction factor smaller than that of the urethane rubber of the main body 6. Instead of baking, a recessed gutter is provided to the top 6a, the buffer reinforced material 10 is buried in the recessed gutter, and bolts can be used for fastening them. For example, the fender 5 is fixed to a quaywall face. Impact force caused by a collision between outside boards is absorbed by elastic deformation of the outside of the main body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fender that protects a ship from damage caused by contact during docking or damage caused by contact between ships docked during berthing or anchoring.

[0002]

2. Description of the Related Art Generally, fenders of this type
The fixed type is permanently attached to the wharf of a wharf or a jetty as a fixed type, and is used for protection to prevent damage to the outer side due to contact due to wave fluctuation when the ship is docked, or if necessary, can be carried freely by a yacht or It is known that it is always installed in small boats such as boats and fishing boats, and it is hung on the outside to protect the hull from collision contact with the wharf pier, pier, or other port that was ported. Materials include wood, rubber, and plastic. By the way, in the case of a fender that is permanently installed as a fixed type and is particularly adapted for berthing of large ships, the larger the friction with the quay wall due to the shaking of the ship during berthing, the stronger the fender is torn. And get damaged early. Depending on the time and duration of the ship's berthing, it has been reported that under severe conditions, it can only last a few months.

[0003]

The present invention is particularly suitable for a permanent fixed type on a quay wall surface, which enhances its durability against tearing due to friction and the like, and a fender which is effective for protecting the outer side of the hull. The purpose is to provide the material.

[0004]

The fender according to the present invention comprises:
It is interposed between the outer ports of ships adjoining each other or between the ships and the berth surface to buffer and protect the outer ports from collision contact, and the outer surface of the elastic main body is more frictional than the main body. It is coated with a cushioning reinforcement made of low friction resin with a small coefficient. For example, in the case of a fender that is formed into a convex shape or a semi-cylindrical shape and is fixed to the berthing surface with mounting flanges provided on both sides of this main body, at least the tip of the convex portion of the main body that abuts the pier The outer surface may be coated with a low-friction resin cushioning reinforcing material by baking, or a cushioning member made of low-friction resin may be combined.

[0005]

Since the outer surface of the main body is covered with the buffer reinforcing material made of a low friction resin having a smaller friction coefficient than that, the frictional resistance due to rubbing is reduced, and tearing and breakage are prevented. The durability of the fender is improved, and it is also effective in protecting the hull.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the fender according to the present invention is a stationary type will now be described with reference to the drawings. Figure 1
FIG. 1 is a plan view of a ship 3 docked on a wharf 1, in which a fender 5 that elastically absorbs and buffers the impact force of the collision contact of the outer port 4 is fixedly provided on the wharf wall 2. The fender 5 is made of urethane rubber and is cushioned by its elastic deformation.

The fender 5 has a main body 6 having a convex cross-section or a semi-cylindrical shape as shown in FIG. 2 so that the cushioning by elastic deformation is effective as a whole. Flange 7, 7 is provided on both sides as a mounting seat for the quay wall surface 4. A reinforcing plate 8 made of a metal plate or the like is joined to the lower surface of the flange 7 for the purpose of enhancing mounting rigidity. Further, the flange 7 is provided with a through hole 9 for a fixing bolt (not shown) penetrating the reinforcing plate 8.

Further, in such a fender 5, the ship 3
The outer side 4 comes into contact with the top portion 6a of the main body 6, and the surface of the top portion 6a has a P smaller than the friction coefficient of the main body 6.
The buffer reinforcing material 10 made of a low friction resin such as TFE (Teflon resin) is coated by baking to a thickness of, for example, about 0.2 to 1.0 mm. The friction coefficient of the main body 6 made of urethane rubber is generally 0.7 to 1.0, and the buffer reinforcing material 10 made of PTFE or the like is a resin having a lower friction than that.

On the other hand, on the other hand, as shown in FIG.
Instead of the form of baking and covering with 0, a structure in which a single plate-shaped cushioning strengthening member 20 is joined as shown in FIG. 3 is also possible. That is, a groove 6b is provided in the top portion 6a of the main body 6 with which the port 4 of the ship 3 abuts, and the plate-like cushioning reinforcing member 20 is fitted flush with the groove 6b.
It was concluded in 1.

In the above two embodiments, the type in which the shore wall 2 is permanently fixed is shown, but the present invention can also be applied to a fender that can be carried around freely and is always equipped in a small boat. is there. Such fenders usually have a columnar shape or the like, and if necessary, they are suspended from the outer port to cushion the contact with other ships or the quay by the port. That is, the buffer reinforcing material 10 or the buffer reinforcing member 20 according to the present invention can be provided on the entire surface or a part of the main surface of the main body which is formed by urethane rubber into a single cylinder.

[0011]

INDUSTRIAL APPLICABILITY The fender according to the present invention is most suitable for being permanently fixed to the wharf wall surface or the jetty in particular, and the outer surface of the main body is covered with a cushioning reinforcing material made of a low friction resin having a smaller friction coefficient than this. As a result, the frictional resistance due to rubbing can be reduced to prevent tearing and breakage, durability can be improved by several steps compared to conventional fenders, and it is effective for hull protection.
