Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cushioning material, and more particularly to a cushioning material interposed between a pneumatic fender and a quay, or between a pneumatic fender and a side of a ship. is there.

[0002]

2. Description of the Related Art Conventionally, in order to protect a shore side when a ship berths and protect a quay or a structure attached thereto, a solid type fender or a pneumatic fender is provided between the hull and the quay. Materials are used. The pneumatic fender is
The one used directly between the ship and the quay, the vertical chain and the horizontal chain are woven so as to intersect with each other, and tires are arranged at the intersections of the chains. The end portion of the fender body is connected to a guy chain connector arranged in the center of the longitudinal end face of the fender body, and a cushioning material configured to cover the outer peripheral surface of the fender body is used. I have.

[0003]

However, a method of directly interposing a pneumatic fender between a ship and a quay is as follows.
There are problems that fenders are pressed against the side of the hull and soil the hull, and that the fenders are rubbed against the quay and wear the fenders, shortening the service life. The method of covering with a cushioning material has a problem that it takes a lot of trouble and time to mount and remove, and requires a large number of chains and tires, resulting in a high cost.

[0004] It is an object of the present invention to contaminate the hull side by providing a buffer between the pneumatic fender and the quay, or between the pneumatic fender and the side of the ship, or to improve the fender. It is an object of the present invention to provide an inexpensive and easy-to-handle cushioning material that can be used without damaging the material.

[0005]

According to the present invention, in order to achieve the above object, a cushioning material according to the present invention is provided between a pneumatic fender and a quay or between a pneumatic fender and a side of a ship. Is a cushioning material interposed in the net braided with a plurality of longitudinal cords and lateral cords, the tire at least at the intersection of the longitudinal cords and lateral cords. The gist of the invention is that it is fixed.

[0006] It is desirable that a flexible sheet be interposed between the longitudinal and lateral cords and the tire. The present invention is configured as described above, and comprises a plurality of longitudinal cords and a lateral cord between the pneumatic fender and the quay, or between the pneumatic fender and the side of the ship. By knitting in the form of a net with a buffer material formed by fixing a tire at least at the intersection of the vertical string material and the horizontal string material, the hull side is soiled, It can be used without damaging, and can be used as a cushioning material that is inexpensive and easy to handle.

In particular, there is a case where a buffer material for a pneumatic fender is not required or cannot be used on a ship side.
Even in such a case, a cushioning material may be required on the quay side to prevent the quay and the pneumatic fender from rubbing. In such a case, the planar cushioning material of the present invention can be effectively used. Further, since the hull side is not to be contaminated with the cushioning material for the pneumatic fender, it is also effective when a conventional net-type cushioning material cannot be used.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side view showing a use state of a cushioning material 1 embodying the present invention, FIG. 2 is a front view showing a mounting state of the cushioning material 1, and FIG. 3 is a plan view of FIG. Denotes a vertical pneumatic fender, 2a denotes a weight attached to the lower end of the pneumatic fender 2, 3 denotes a ship, 4 denotes a side surface of a quay, and 5 denotes a seabed.

The cushioning material 1 comprises a pneumatic fender 2 and a quay 4
(Or between the pneumatic fender 2 and the side surface of the marine vessel 3, not shown). The cushioning material 1 is knitted in a net shape by a plurality of longitudinal string members 6a and horizontal string members 6b each composed of any one of a chain, a wire rope, and a fiber rope.
The tire 7 is fixed to at least the intersection 6Q between the tire 7 and the lateral string material 6b.

The longitudinal string material 6a constituting the cushioning material 1
The upper end of the quay 4 is fixed to the upper part of the quay 4 (or the upper part of the side of the ship) via a fixing bracket 8 or the like, and the lower end is hung along the side of the quay 4 (or the side of the ship). In addition, the lower end of the vertical cord 6a may be attached with a weight (not shown) to apply tension to the cushioning material 1, or may be fixed below the seabed 5 or the side of the quay 4.

Further, an intersection 6Q between the longitudinal string material 6a and the lateral string material 6b of the cushioning material 1 is connected by a four-way shackle 9 as shown in FIGS. 2, 4 and 5. I have. In addition, the vertical string material 6a and the horizontal string material 6b
A flexible sheet 10 is interposed between the tyre 4 and the inner wall surface of the tire 7, and a longitudinal string 6a, a lateral string 6b and a four-way shackle 9 made of a metal material such as a chain are used for the quay 4 and the hull side. It is also possible to protect the device from direct contact.

As described above, between the pneumatic fender 2 and the quay 4 (or between the pneumatic fender 2 and the side of the ship 3)
The plurality of longitudinal cords 6a and the lateral cords 6b are knitted in a net shape, and the longitudinal cords 6a and the lateral cords 6 are knitted.
By interposing the cushioning material 1 configured by fixing the tire 7 at least at the intersection 6Q with the b, the hull side is soiled,
The pneumatic fender 2 can be used without damaging it, and can be used as a cushioning material that is inexpensive and easy to handle.

In particular, even when the cushioning material for the pneumatic fender 2 is not required or cannot be used on the ship 3 side,
On the quay 4 side, the cushioning material 1 may be required in order to avoid the friction between the quay 4 and the pneumatic fender 2. In such a case, the cushioning material 1 of the present invention can be effectively used, and the hull side is not to be contaminated with the cushioning material 1 for the pneumatic fender 2, or a conventional net-type cushioning material is used. It can be used effectively even when it cannot be used.

Further, when the ship 3 is not berthing, it is possible to prevent abrasion of the pneumatic fender 2 caused by rubbing against the quay 4 due to rocking of the pneumatic fender 2 due to waves or the like.

[0015]

The present invention relates to a cushioning material interposed between a pneumatic fender and a quay, or between a pneumatic fender and the side of a ship, as described above. The knitting of the cords and the lateral cords in a net shape, and the tires are fixed to at least the intersections between the longitudinal cords and the lateral cords, so that the hull side is soiled or the fender body itself It can be used safely without damaging it, and it is easy to install and remove, so repair and replacement of cushioning materials can be performed efficiently in a short time, and the structure is simpler than conventional cushioning materials. Since the number of parts is small, it can be manufactured at low cost.
