Description

[Detailed description of the invention] This invention relates to a rubber fender that can be used by dock workers, boat passengers, fishermen, etc. who accidentally fall into the sea to use their own blades to climb up to the quay and save their lives from danger. .

In recent years, many structures such as quays and seawalls in ports have been built upright, so if a person accidentally falls into the water, they can use their own blades to climb up these upright structures and escape from the water. It's gone.

Therefore, in these upright structures, it is now mandatory to arrange self-sabotage rescue ladders at appropriate intervals as a safety measure in such cases.

Ladders that are currently widely used are those made of metal such as iron, or iron with rubber lining to prevent rust.However, these ladders can be damaged if the ship's side plate collides with the ship when it is berthed. Since it can damage not only itself but also the side panels, it is usually installed in a location where it does not interfere with the berthing of ships.

On the other hand, the distance a person can swim fully clothed in the sea during extremely cold weather is said to be around 30 meters, although this varies from person to person.

Even under such extreme conditions, people who are not good at swimming often cannot even swim to the position where the iron ladder is installed.

Therefore, it is desirable that self-help ladders be installed at shorter distances.

However, as mentioned above, conventional iron ladders cannot satisfy the above conditions because they damage the ship's hull.

Recently, in view of the above-mentioned circumstances, various rubber life ladders have been proposed, and the present applicant has already developed and filed applications for many rubber ladders.

This invention provides a new life-saving means created through a series of research and development processes, and its gist is not to create a special structure as a life-saving ladder, but to install it on the quay as a cushioning material for berthing. The key point is to utilize the existing rubber fender as is and attach ropes to it that serve as handholds and footholds for climbing.

In the present invention, conventionally known quay-mounted rubber fenders are utilized.

Examples include cylindrical round fenders and oblong hollow fenders with various cross-sectional shapes such as semicircular, square, and trapezoidal shapes, and these fenders have their longitudinal direction facing the water surface. It is used so that it is perpendicular to the surface of the quay, that is, so-called 1-vertical.

It is also possible to use a so-called one-assembly type fender device in which an impact-receiving plate is installed between one end of a pair of rubber fenders having a single-shaped cross section.

These fenders are usually attached to walls at intervals of about 4 m to 15 m depending on the water depth to protect the ship's hull and quay structures.

Therefore, by using these, it is possible to provide a suitable means of lifesaving for people who are not good at swimming or those who fall into the sea during the cold season, and there is no risk of damaging not only the body itself but also the hull of the ship. .

According to the present invention, through holes are bored in the side walls of the various fenders above, and ropes serving as handholds and footholds for climbing are passed through these holes.

Both ends of the rope may be fixed to the quay attachment portion of the fender using anchor bolts used for fixing the fender to the quay.

However, since anchor bolts are usually installed at intervals of about 60 cm to 1 m, the distance between them is too wide for use as a handhold or foothold member for climbing.

Therefore, we usually use a reinforcing iron plate buried in the attachment part of the fender, and attach rope attachment fittings to this plate with a length of 30cm to 5cm.
It is best to attach them at 0cm intervals to secure both ends of the rope.

Accordingly, the rope through-holes bored in the side wall of the fender are also spaced at intervals of 30 cm to 50 cm.

The rope may be made of various fiber materials such as cotton, hemp, polyamide, etc., or may be made of comb-coated wire or comb-coated wire.

The rope may also be colored in a suitable color, such as yellow, to make it more visible.

The present fender can also be provided with an auxiliary rope 2' that hangs down between the mounting brackets 5, 5, as shown by the dotted line in FIG.

With this structure, a person who falls into the water can temporarily hold on to the rope and then use the climbing rope 2 to escape to the top of the quay.

Also, if you do not have the physical strength to climb with your own knife, you can shout for help while holding on to the auxiliary rope 2'.

As described above, the present invention makes effective use of the rubber fenders originally installed to protect ship hulls and quay structures, and by attaching ropes that serve as handholds and footholds for climbing. Provide emergency evacuation means for people who fall into the sea.

Moreover, the rope is passed through the side wall portion so as not to impede the original function of the fender, and the rope itself is designed so that it will not be damaged by the ship coming alongside.

Examples of the present invention will be described below.

Fig. 1 is a plan view of a 1-inch type fender to which the present invention is applied, and Fig. 2 is a sectional view of the fender shown in Fig. 1.

The fender 1 of this example has a length of 1) 1000-rrrIn1 and a height of 300 mIIL, and a pair of side walls 1b have a plurality of through holes 3 of 400 mm.
It is perforated at wn intervals i.

Polyamide rope (nylon rope) 2 for hole 3.
... is inserted, and both ends of each rope 2 are attached to mounting brackets welded to the reinforcing iron plate 4 buried in the quay wall attachment part 1c of the fender 1, as shown in FIG. It is fixed at 5.

When the fender 1 acts as a buffer, the rope 2 must not inhibit the bending and deforming action of the side wall 1b.

Therefore, the rope 2 should have sufficient length, and the through hole 3 should be formed with a sufficiently large diameter so that the rope 2 can freely pass through.

As shown in FIG. 3, it is preferable for the fender 1 of this embodiment having the above structure to be vertically attached to the quay wall for the purpose of the invention.

However, even if the so-called 1-horizontal attachment parallel to the water surface is decided against, a person who falls into the water can grab onto the rope 2 and use it as a life-saving means to loudly call for help, even though it is not possible to climb up to the top of the quay.

In this example, a so-called RV-shaped fender with a trapezoidal cross-sectional shape was used, but as mentioned earlier, various cross-sectional shapes such as circular, semicircular, square, inverted Y-shape, etc. It can also be applied to hollow cylindrical fenders.

It can also be applied to single-assembly type fenders such as those on the next side.

FIG. 4 is a perspective view showing an embodiment in which the present invention is applied to a single-assembly type fender developed for large ships.

The device of this example consists of a pair of rubber fenders 1, 1' and an impact receiving plate 6 installed between one end of each fender 1, with the other end of each fender 1 being It is fixed to the quay.

In addition, the height h) of each fender 1 is 100-1 length 1)
is formed to have dimensions of 150,071vn, and the impact receiving plate 6 is constructed by attaching an impact receiving bat 6b made of a hard comb or plastic to the front surface of a frame 6a made of angle steel.

The rubber fender 1 has an interval (i) of approximately 3 along its longitudinal direction.
A through hole 3 is drilled every 50 TrrIIL, and a rope 2 is inserted through the hole 3 across the inside, outside, and inside of each fender 1, and both ends of the rope 2 are attached to the quay wall attachment part IC of each fender 1. It is fixed to the mounting bracket 5.5 which is fixed in the same manner as in the previous example.

Although not shown in FIG. 4, a similar rope 2 is attached to the other rubber fender 1.

As described above, the present invention contributes to the improvement of port facilities by combining an emergency evacuation means with a rubber fender capable of absorbing and mitigating the impact force received from ships.
