[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net-shaped life-saving device, and more specifically, to a rectangular net-like body formed by knitting ropes, cords, and other rope-like materials, and both side edges of the net-like body. It consists of buoyant bodies attached to the upper and lower edges, and it can be easily and quickly deployed automatically when it is put into the sea when an accident occurs, and it can be rescued by a fallen person by tangling his limbs with the net, and the rescue range is extremely wide. In addition, the present invention relates to a net-like life-saving device suitable for a small boat that requires a small storage space.

2. Description of the Related Art Usually, due to slight carelessness and negligence,
A fall accident from a ship into the sea occurs, especially during fishing. Rescue of a fallen person in the event of an accident can be easily performed with a small ship that can be maneuvered freely, but with a large ship, maneuvering can not be done freely as intended, and it reaches the drop position. It takes a considerable amount of time to do this, and depending on the conditions of the falling water area, it may not be possible to approach them, making rescue difficult or impossible. Especially, in recent years, leisure-like operations by small fishing boats have increased, but a fall accident by this small fishing boat, etc. may be a rescue area because the falling water area is a shallow water area or a reef. Therefore, it cannot be approached by a large vessel. In addition, a fall accident that occurs during fishing in the North Sea, Antarctica, etc. is extremely difficult due to poor sea conditions and a limited rescue work range. Therefore, it is extremely difficult to save life with rescue equipment such as lifebuoys, rafts, and life jackets.

That is, in Japan, according to the Ship Safety Law and its enforcement regulations, it is stipulated that a lifebuoy, a life jacket, a life raft, a lifeboat, and other equipment be provided on a ship according to the size of the ship and the number of people on board. There is. However, if it is possible to rescue a fallen person by putting these life-saving equipment into the sea, it is a water area with a relatively good sea condition, and even in such a water area with a good sea condition, as described above, the ship is a rescue site. It often takes time to reach them and they are often too late to be rescued. Contrary to this, where fishing is performed, the sea conditions are poor due to stormy and cold waters, and in the event of a fall accident during fishing, even if the vessel could approach in a short time and put in lifesaving equipment,
It is difficult to pick up and rescue in areas where the sea condition deteriorates because the rescue work area is narrow.

More specifically, when a person who falls into the sea occurs, even if a lifebuoy or a life raft is thrown into the sea, the lifebuoy and lifesaving are caused because the fallen person is extremely tired in the sea area where the sea condition deteriorates. It does not have the power or ability to be caught spontaneously by rafts and cannot swim to lifebuoys. Especially,
The violent wind and waves cause the lifebuoy and life raft etc. that have been thrown into the leeward direction, and those who have fallen into the sea are affected by the ocean current, tidal current, etc., so it will take time for the vessel to approach and rescue work by the lifebuoy after approach. The current situation is that it is difficult for itself.

Therefore, the present inventors have developed a life-saving device consisting of a net-like body in which a rope-shaped material is woven, in place of the life-saving device such as the lifebuoy, the liferaft, and the lifejacket of these conventional examples, The lifesaving equipment was actually loaded on a ship and a test study was conducted. This life-saving device is composed of a net-woven body made of a rope material of natural or synthetic fiber, and while attaching a buoyant body along a part of both side edges of the net-like body, the life-saving device is pivotable on the mast of a ship. The upper end of the mesh is suspended by the attached boom material.
It is configured so that it can be hung via a cable. Since the main body of this life-saving device consists of a mesh body, it can be thrown to a relatively distant place compared to the conventional lifebuoy and life raft, and at the time of rescue, even if the main body consists of a mesh body. Since the buoyant body is attached to both side edges, both side edges of the net-like body levitate, and the fallen person can put his foot or hand in each mesh of the net-like body, and the fallen person is considerably used. Even, you can surely grab a life-saving device.
This life-saving device winds up the suspension rope and pulls it up on the ship, but at this time, if the fallen person entangles his body with the net, it is not always necessary to grasp the net with the hand and be sure to put it on board. It can be pulled up, and when the suspension rope is wound up, it is swung until the tip of the boom material reaches the top of the ship, and the fallen person can wind the body around the net relatively easily. Can be rescued.

[0006] In short, the life-saving device has a main body composed of a mesh body, and the advantages of the mesh body can be fully utilized.
On top of that, the life-saving range is expanded, and in this way, a reliable life-saving of the fallen person is achieved. In addition, since the body of the life-saving part cannot be configured as a mesh body and buoyancy cannot be imparted to itself, buoyancy bodies are attached to both side edges of this mesh body to give a certain degree of buoyancy to the mesh body. In other words, since the falling person has a net-like structure that is easy to grasp or wrap around the body, even if the falling person is considerably stuck, it can be easily grasped and entangled in the body, and the net body is originally flexible. Since it is extremely light and lightweight, it can be thrown to a relatively distant place, it can be rescued even if the ship is not close to the falling site, and it can be folded compactly so that it can be stored on the ship without taking up space. .

However, when the life-saving device of this structure is actually used, the buoyancy body attached to a part of both side edges of the mesh body gives buoyancy, but other parts of the mesh body are
In other words, if the buoyant body is concentrated on the upper part, the other part that is not installed, that is, the lower part will sink into the sea, making it difficult for a person with a large degree of fatigue to fall into the bottom of the body. Even though I entangled him, I was shaken out by the waves and I couldn't rescue as much as I expected.

Further, since the buoyant bodies attached to both side edges of the net-like body are formed as an integral body, the integrated buoyant body may not be entangled in the net-like body to be expanded when thrown into the sea. Moreover, the net-like body is a flexible one made by knitting a rope-like material, and it does not spread easily when it is unrolled at the time of storage and unfolded at sea or in the sea. So when an accident occurs, this difficulty in spreading is a big problem.

Therefore, as a result of various researches conducted by the present inventors, it was found that the rescue equipment consisting of a net-like body formed by knitting a rope-like material and buoyant bodies attached to both side edges of the rescue equipment is in poor sea condition. Also, it can be easily rescued, and in particular, it can be rescued even if the ship does not approach the rescue site so much, and even if buoyant bodies are provided over the entire length of both side edges of the mesh body, these buoyant bodies do not become an obstacle at the time of rescue, In addition to being compactly stored, a net-type life-saving device that can be easily opened in the sea was proposed (see Japanese Patent Laid-Open No. 3-284498).

In this net-shaped life-saving device, if a plurality of buoyant bodies are attached to each mesh of the mesh over the entire length of both side edges of the mesh formed by knitting the rope-shaped material, the mesh-like body becomes compact when stored. It can be wound and can be easily unwound at sea. Also, long materials are attached to the upper and lower end edges of the mesh body so that the long material is hung from one of the two end edges of the mesh body. It has a certain buoyancy. Also,
A plurality of buoyant bodies are individually and linearly provided on at least a part of a substantially central portion of the mesh body. Therefore, the reticular body is given sufficient buoyancy where the buoyant body is provided in the center in the sea, and the place where the buoyant body is not provided is sunk. It can be rescued simply by twisting it. A net-shaped life-saving device consisting of such a net-like body is easier for a faller to grasp than life-saving floats, life jackets, and life rafts of the conventional example, and among them, unlike the life raft, wind waves, ocean currents, tidal currents. Although there is an advantage that it will not be affected by the above, there is a case where the long material hangs on the net etc. and it may not be automatically expanded, it takes a long time to save lives, and a wide space was required for storage. .

[0011]

The present invention aims to solve the above-mentioned problems. Specifically, when an accident occurs, it can be easily and quickly automatically deployed when it is put into the sea, and a fallen person can entangle a limb with a net-like body. The purpose is to propose a net-shaped life-saving device that can be rescued by itself and is suitable for mounting on a small ship tower.

[0012]

That is, the present invention is based on
It consists of a rectangular net-like body made of braided braided material, and a plurality of buoyant bodies are attached to each mesh of the net-like body over the entire length of both side edges and upper and lower end edges of the net-like body. One of the meshes is configured to be lifted from one edge, and a plurality of buoyant bodies are individually and linearly provided for each mesh at a predetermined position between both side edges of the mesh.

Now, the structure and operation of these means will be described more specifically with reference to the drawings.
It is as follows.

First, FIG. 1 is a plan view of a net-like life-saving device according to one embodiment of the present invention. In FIG. 1, reference numeral 10 generally indicates a net-like life-saving device according to one embodiment of the present invention. The life saving device 10 is mainly shown in FIG.
And a plurality of buoyant bodies 12. This mesh 1
Reference numeral 1 is a rectangular shape in which a mesh 112 is formed by weaving a loop material 111 of natural or synthetic fiber.
Further, a plurality of buoyant bodies 12 are attached to each mesh 112 over the entire length of both side edges of the mesh 11. This attachment can be performed on either side, but the buoyancy body 1 is attached to each mesh 112.
Each buoyant body 12 is individually fixed by passing the rope-shaped member 111 through 2. By fixing the buoyancy body 12 to each mesh 112 in this way, as will be described later, the buoyancy body 12 can be easily wound during storage and can be quickly deployed during use. In particular, the buoyant body 12
Are attached over the entire length of both side edges of the net-like body 11, the both side edges of the net-like body 11 float over the entire length in the sea, and the fallen person can easily grasp the both side edges in the floating state.

Further, buoyant bodies are individually attached to the upper and lower end edges of the net-like body 11 for each mesh in the same manner as the both side edges. When the buoyant body 12 is attached to both upper and lower edges in this way, it is not caught on the net body 11 or the like unlike the long member of the conventional example.

Further, for example, ring members 151 and 152 are attached to the upper end of the net-like body 11, lifting ropes 161 and 162 are attached via the ring members, and the upper ends of these lifting ropes 161 and 162 are wound up. -Connect to p17. With this structure, the person who has fallen in the event of an accident can be smoothly pulled up together with the net body 11 simply by winding up the winding rope 17.

In the net-shaped life-saving device having the above structure, a plurality of buoyant bodies 12 are individually attached at predetermined positions in the mesh between both side edges of the mesh 11. With this structure, the buoyancy body 12 separates the space from both side edges, and the rate at which the mesh body 11 is automatically expanded becomes large.

The net body 11 is levitated by buoyant bodies 12 attached to both side edges and upper and lower end edges of the net body 11. The portions sandwiched by the buoyant bodies 12 are submerged in the sea, and the cross section of the net body 11 in the sea is downward. To bend. Therefore, the fallen person can grasp the net-like body 11 only by putting his / her body on the curved portion, and can be quickly rescued. However, even if the fallen person leans on the lower end of the net body 11 in this way, the weight of the net body 11 causes the net body 11 to sink into the sea, causing the head to enter the sea, which in turn causes loss of human life. It will happen. Therefore, the buoyancy bodies 12 are individually attached to the predetermined positions between the both side edges of the net-like body 11 in a straight line, and the net-like body 11 is standing upward even when the person falls down in the sea. To be able to be held.

Further, the net-like body 11 is provided with buoyant bodies 12 along both side edges thereof, and a hand rope 19 is provided so as to straddle each buoyant body 12 on both side edges. That is, the reticulate body 1
A plurality of buoyant bodies 12 are provided on both side edges of the entire length 1
Is provided so that the cross section of the net-like body 11 is curved or arcuate in the sea as described above. However, while the buoyancy body 12 can easily rescue the fallen person, the buoyancy body 12 becomes an obstacle when the fallen person grasps the side edge of the net-like body 11. From this point, a hand rope 19 is provided in order to cover each buoyancy body 12.

Further, in the lifesaving device having the above-mentioned structure,
It is more preferable to configure as follows.

First, each of the rope-shaped members 111 constituting the net-like body 11 is composed of natural or synthetic fibers, is less deteriorated by weathering or seawater, and has a specific gravity which is substantially equal to or heavier than that of seawater. However, a slightly heavy one is preferable. The tensile strength is 1000 kg / cm ²
The above is preferable. The reason is that, for example, the tensile strength is such that two people do not cut even if they have the same mesh.
It will contain 0 kg of seawater, and if this is added, it will be 180 kg for two people. Furthermore, the drop in the tensile strength of the rope-shaped material 111 in the sea is expected to be 15% inside or outside, and considering the safety factor, a load of 300 kg or more is applied to the mesh, and considering the safety of human life, the tensile strength is 1000 kg.
/ Cm ² or more is required.

Further, since the net-like body 11 entangles the limbs, if it is extremely thin, the human body will be damaged, and in this sense, it will be low.
It is preferable that the cup-shaped member 111 has a diameter of 6 mm or more.

Next, each buoyant body 12, 18 is preferably made of foamed synthetic resin, and the size of each body is, for example, 1
It is about 73 × 113 × 26 mm and its buoyancy is 1.
It is preferably 2 kg or more. That is, at least about 10 kg of buoyancy is required to support the human body. For example, if 4 people are rescued at once and they do not sink, a total of 40 buoyancy bodies will be attached, 40 pieces x 1. 2 kg
= 48 kg.

It is preferable that the surface of each buoyant body 12, 18 be coated with a reflective or fluorescent paint. It is preferable that such a paint is applied because it is easy for a fallen person to find it even at night and the seawater resistance is improved.

Each mesh of the mesh body 11 can be formed in any shape, but a square shape is sufficient, and in any case, the human body does not come out, and the mesh size may be about 250 m / m, for example.

Further, at both side edges of the mesh body 11, a hand rope 19 is provided so as to surround at least one buoyant body 12.
However, it is preferable that this diameter be substantially equal to that of the rope-shaped member 111.

[0027]

As described in detail above, in the net-like life-saving device according to the present invention, a plurality of buoyant bodies are attached to each mesh of the net-like body over the entire length of both side edges of the net-like body in which the rope-shaped material is knitted. Of the upper and lower edges of the mesh body, it is configured to be hung from one edge, and a plurality of buoyant bodies are individually and linearly provided at predetermined positions between both side edges of the mesh body. It is characterized by

Therefore, when an accident occurs in the sea, it can be automatically deployed immediately after being thrown into the sea, and a fallen person with a large degree of fatigue can be easily rescued. Further, the life saving device is small and requires a small storage space, which is a preferable life saving device for small ships.
