Description

[Detailed description of the invention] The present invention relates to a floating fender device, and more specifically, when a ship comes alongside a structure such as a pier or quay, it absorbs the energy of coming alongside and prevents damage to the ship. , relates to improvements in floating fenders for protecting structures.

Conventionally, this type of floating fender F generally has a fender main body A having buoyancy, such as an air fender or a foam fender, as shown in FIGS. 1 and 2.
is moored to the structure G by a mooring device K such as a chain attached directly to the fender main body A or via a chain (not shown), and the ship is moored to the structure G. When the vessel comes alongside, it absorbs the energy of coming alongside, thereby preventing damage to the vessel and protecting the structure G.

However, in the conventional floating fender F having the above-described structure, the length of the mooring device K is adjusted to the highest and lowest tide levels so that the fender main body A can move up and down following fluctuations in the tide level. It has been made longer.

Therefore, if the tide level is the normal tide level, that is, the middle tide level between the highest and lowest tide levels, it is inevitable that
As shown in Figure 1b, the fender main body A and the structure G
Looseness (gap) will occur between the two. As a result,
Problems such as the fender body A moving sideways due to the effects of tidal currents (water currents) and wind and waves, or the fender body A being repeatedly struck against the structure G by waves crashing during bad weather, resulting in early damage. The current situation is that there is.

The present invention was developed as a result of studies to solve the above-mentioned problems.

Therefore, the purpose of the present invention is to provide an excellent floating fender device that not only allows the fender body to follow changes in the tide level, but also allows the fender body to be in constant contact with the surface of structures such as bridge piers and quays. It is about providing.

That is, the present invention consists of a fender main body having buoyancy and a mooring device for mooring the fender main body to a structure such as a bridge pier or a quay. Its gist is a floating fender system characterized by a weight that is towed on the side.

Hereinafter, the present invention will be explained in detail by way of examples with reference to the drawings.

Figures 3 to 5 show a floating fender according to an embodiment of the present invention, and Figures 3a to 3c show the floating fender in a state moored to the side of a bridge pier, that is, a structure, respectively. Fig. 4 is a side view explanatory diagram showing a state in which the tide level is at the highest level, b shows a state in which the tide level is the normal tide level, that is, an intermediate tide level between the highest tide level and the lowest tide level, and c shows a state in which the tide level is at the lowest tide level. FIG. 5 is an explanatory plan view of the same as above, and FIG. 5 is an explanatory side view showing a state in which a floating fender according to another embodiment is moored to a bridge pier, that is, a side side of a structure.

In the figure, E is a floating fender device consisting of an embodiment of the present invention, and a fender main body 10 having buoyancy.
Then, this fender main body 10 is attached to a structure G such as a bridge pier or a quay.
This mooring tool 2 consists of a mooring tool 20 that is moored to
0 is provided with a weight 30 that constantly pulls the fender main body 10 toward the structure G.

To further explain this structure, the fender main body 10 is formed of a rubber-like elastic body in which a reinforcing layer (not shown) is embedded into a vertically elongated hollow body (bale shape) as shown in the figure. It is constructed by filling air into the mirror parts 1 on both the left and right sides.
At the center of 0a and 10b, there is a mooring tool attachment part 11.
is provided.

In this embodiment, the mooring device attachment portion 11
The base plate 11a is integrally attached to the center of each of the mirror portions 10a and 10b, and the U-shaped hook 1 is protruded from each base plate 11a.
1b, each U-shaped hook 1
1b, a mooring device 20 whose base 20a is attached to an anchor Ga embedded in the structure G, that is, a distal end portion 20b of a chain is attached via a shackle 40.

In the first embodiment shown in FIGS. 3 and 4, the weight 30 is attached to the intermediate portion of the mooring device 20 as shown in the drawings, and keeps the fender body 10 always on the structure G side. The fender main body 10 is towed so as to follow the fluctuations in the tide level, and the fender main body 10 is always in contact with the surface of a structure G such as a pier or a quay.

Further, in the second embodiment shown in FIG. 5, the above-mentioned weight 30 is attached to a mooring tool 20 suspended from a pulley Gb (the anchor Ga described above may also be used) rotatably supported on the structure G, as shown in the figure. It is attached to the free end, and constantly pulls the fender main body 10 toward the structure G side to make the fender main body 10 follow the fluctuations of the tide level. It is arranged so that it can come into contact with the surface of the structure G.

Reference numeral 50 in the figure is a rubber sleeve attached to the mooring device 20, that is, the chain, and when the fender main body 10 is shaken by waves etc.
0 can be prevented from rubbing against the structure G and being worn out.

As mentioned above, the present invention consists of a fender main body having buoyancy and a mooring tool for mooring the fender main body to a structure such as a bridge pier or a quay. Since the weight to be pulled toward the structure is provided, not only can the fender main body follow changes in the tide level, but also the fender main body can always be in contact with the surface of structures such as bridge piers and quays. Therefore,
To prevent the fender body from moving laterally due to the influence of tides (water currents) and wind and waves, and to prevent the fender body from being repeatedly struck against the structure by waves crashing in bad weather. is possible,
It is possible to prevent the fender main body from being damaged at an early stage.
