Description

[Detailed description of the invention] <Industrial application field> This invention relates to fenders installed at the berthed parts of ships, quays, marine structures, etc., and in particular covers fenders such as air bags. Nets such as chains or wires installed may cause dents in the hull or peeling of paint when berthed.
The present invention relates to an improved fender that can protect the hull from damage.

<Prior Art> As a conventional fender, there is one having a structure as shown in FIG. 3, for example. Specifically, numeral 1 is an air bag made of, for example, rubber and generally shaped like a bag, and a mounting net 2 made of a chain or wire is placed over the air bag 1. This pneumatic fender is
It is attached to the hull or quay by a hanging chain or wire 3 connected to both ends.

Figure 4 shows another example of a conventional fender, such as the type shown in Japanese Utility Model Publication No. 57-36552.
An air bag 5 made of rubber is covered with a net 6 made of, for example, a chain. With respect to the air bag 5 of the net 6, the horizontal chain 7 and the vertical chain 8 respectively pass through old automobile tires 9, 9..., so that the old tires 9, 9... It is fixed at the joint between the chain 7 and the longitudinal chain 8. longitudinal chain 8,
Both ends of 8... are each connected to a connecting ring 10, and chains 11, 11 for hanging are further connected to this connecting ring 10.
The lateral chain 7 and the longitudinal chain 8 are connected to the connecting ring 12 and the shackle 13, 13, 14, 14 at the center of the tire 9, for example, as shown in FIG.
are connected to each other by.

For example, as a conventional fender other than the above,
As shown in Japanese Patent No. 66396, there is a chain-net chain covered with a fender such as an air bag and covered with an elastic sleeve made of rubber hose or nylon.

<Problems that the invention is trying to solve> With the conventional fender shown in Figure 3, when the ship is berthed, the ship's hull is rubbed directly against, for example, the chain net 2, causing the paint on the ship's hull to peel off and the ship's hull to be dented. It had the disadvantage of being able to do it.

The conventional fender shown in Figure 4, or the type of fender in which the chain forming the net is covered with an elastic sleeve, will cause less damage to the ship's hull than the fender shown in Figure 3. However, since the tires or elastic sleeves are also compressed at the same time as the fender is compressed when berthed, the intersection of the net's transverse chain and longitudinal chain comes into direct contact with the ship's hull, causing the paint on the ship's hull to peel off. There were drawbacks such as denting of the hull and denting of the hull.

<Means for solving the problem> The fender according to this invention has a fender made of an air bag made of rubber, for example, and a chain or wire net covered with the fender. There is. Both the transverse chains or wires and the longitudinal chains or wires forming the net pass through the tire and are connected to a connecting fitting which is housed within the annular cavity of the tire.

<Function> In the fender according to this invention, the chain or wire that constitutes the net, as well as the connecting fittings, are not exposed in the wheel hole in the center of the tire, so the tire is compressed when the ship berths. Even if the chain, wire, or connecting fittings do not come into direct contact with the ship's hull, the ship's paint will not peel off or the ship will be dented or otherwise damaged during docking.

<Example> The fender of this invention will be explained with reference to the example shown in FIGS. 1 and 2. The basic structure of the fender is almost the same as the conventional fender shown in Figure 4.
A fender 50 made of, for example, an air bag is covered with a net 6 made of, for example, a chain. Old automobile tires 9, 9 are placed in the net 6 at positions where, for example, horizontal chains 7, 7, . . . intersect with vertical chains 8, 8, . As shown in FIGS. 1 and 2, a steel ring 15 is inserted into the tire 9 as a metal fitting for connecting the chain. The diameter A of this ring 15 is larger than the wheel diameter B of the tire 9, but it is determined to such an extent that this ring 15 can be inserted into the tire by utilizing the elasticity of the tire itself. Both the transverse chain 7 and the longitudinal chain 8 forming the net 6 pass through the tire 9 and are connected to the ring 15 by means of a shackle 16 and a small ring 18, respectively.

In the above embodiment, a highly rigid steel ring 15 was used as the connecting fitting, but in addition to this, a chain ring 15a as shown in FIG. 6 or a wire ring 15b as shown in FIG. It may be a flexible extension ring. In the same figure,
Parts equivalent to those in Figure 2 are indicated by the same drawing symbols.
20 is a steel fitting, and 21 is a wire connection part.

In addition, in the above embodiment, the chain or wire forming the net connected to the connecting fitting is connected at four points, but
It can also be applied to cases where there are 3, 5, 6 locations, etc.

<Effects> According to this invention, the wheel hole 17 at the center of the tire 9 not only has the connecting ring 15, but also the connecting ring including the shackle 16 and the like, and the vertical and horizontal chains or wires constituting the net. Since the parts are not exposed at all, even if the tires 9 are compressed when the ship is berthed, the net and the above-mentioned connecting rings will not come into direct contact with the ship's hull. There will be no peeling of paint or dents on the hull. In addition, the shackle 16, 16 is used instead of the connecting ring.
A polygonal connecting fitting with a corner at the position may also be used. Further, the net is not limited to the vertical and horizontal square shapes as in the embodiment, but may be formed in a diamond shape, a hexagonal shape, or the like.
