Description

  The present invention relates to a life preserver, and more particularly, to a life preserver that can be easily discovered from a mother ship or the like when a diver or an angler requests relief.

  Conventionally, in order to discover divers that have emerged from the sea and anglers who have fallen to the surface of the sea, etc. from the mother ship, they have relied on the sight of seafarers and rescuers. However, it is not easy to find divers and the like that have surfaced on the sea by visual observation from the mother ship, and there is a possibility that the divers will drift on the sea for a long time due to delay in raising them to the mother ship or cause a worst situation.

  Therefore, it is also conceivable to discover a diver that has surfaced on the sea, not using visual recognition, but using radar. For example, Patent Document 1 describes that it is easy to find by radar reflection, and is compact and has excellent storage properties. As a lifesaving device, a material having at least one of a metal foil transfer fabric or a metal foil vapor-deposited film as a base material and a concavo-convex process on the surface of the base material has been proposed.

  In addition, the applicant has improved the reflectance with respect to the radar radio wave, and when it is filled with a gas lighter than air so that divers or victims who have levitated the levitating body can be easily found by the radar, Proposed a floating body for indicating a location, which includes a floating body that is substantially a combination of planes (see Patent Document 2).

  However, even when using the above-mentioned life preserver etc., not only divers themselves are very small compared to the surface area of the sea, but also when the sea waves are high, radar waves are reflected by the sea surface and waves on the sea surface. Therefore, there is a problem that it is not easy to capture divers and the like with a radar.

  Therefore, the present invention has been made in view of the problems in the above-mentioned conventional life preserver, etc., and it is possible to easily find a diver or the like even when the ocean wave is high, etc. The purpose is to provide.

  In order to achieve the above object, the present invention is a life-saving device, which is formed of a telescopic support, a flag mounted on the upper end of the support, and a material that reflects radar radio waves, and is fixed to the flag And a weight mounted on the lower end portion of the column, and a floating body mounted on the column above the column.

  According to the present invention, when a diver or the like seeks relief, the flag attached to the upper end of the column is swung by the wind by extending the column, and accordingly, the radar radio wave is reflected. Since the flip piece formed of the material is turned, it is easy to reflect the radar radio wave, and it is easy to find a diver or the like via the radar even when the sea wave is high. In addition, the weight and the floating body attached to the lower end of the support post can maintain the entire life preserver in a stable state on the sea or the like. Furthermore, since the column is formed to be extendable and retractable, it is convenient for carrying.

  In the lifesaving device, the support column may be configured to include a plurality of telescopic hollow poles and extendable by air introduced into the hollow poles. This makes it possible to easily extend the column even at sea using an air cylinder or the like.

  In the life-saving device, the flip piece can be formed in a planar rectangular shape, and an end portion far from the support can be fixed to the surface of the flag body. As a result, when the flag body sways in the wind, the flip piece sways in the direction perpendicular to the surface of the flag body, making it easier to reflect radar radio waves and making radar discovery easier. .

  ADVANTAGE OF THE INVENTION According to this invention, a diver etc. can be discovered easily even when the wave on the sea is high, etc., and a life preserver convenient for carrying can be provided.

  FIG. 1 shows an embodiment of a life preserver according to the present invention. This life preserver 1 is roughly classified into a telescopic support 2, a flag 3 attached to the upper end of the support 2, and a radar radio wave. The revolving piece 4 is formed of a material that is attached to the flag body 3, the weight 5 is attached to the lower end of the support 2, and the floating body 6 is attached to the support 2 above the weight 5. Is done.

  The support column 2 is formed so as to be telescopically extendable in a fishing rod shape by a plurality of hollow poles, and is configured to have an overall length of about 5 m. The lower part of the support column 2 is integrated with the floating body 6 and the weight 5 while being inserted into the floating body 6. The lowermost pole 2a is provided with an air inlet 2b, and the column 2 can be extended by air introduced into the column 2 from the air inlet 2b. In filling air into the support column 2 from the air intake port 2b, an air cylinder or the like can be used, and a coupling member with an air cylinder having a plug that can be opened and closed is provided at the air intake port 2b.

  A flag body 3 is attached to the uppermost pole 2 c of the column 2. The flag body 3 is formed of a waterproof and water-repellent material such as plastic fabric such as thick nylon or polypropylene, and has dimensions of about 50 cm in length and about 70 cm in width. As shown in FIG. 2, the flag body 3 is folded at one side end portion for reinforcement, and the folded portion 3a is perforated to form a hole portion 3c by the eyelet 3b. The ring 7 is inserted into the hole 3 a of the flag body 3 shown in FIG. 1 and the uppermost pole 2 c of the column 2 is inserted through the ring 7, so that the flag unit 3 is attached to the column 2. At the uppermost part of the pole 2c, the corner of the flag body 3 is fixed with a string 9 or the like, and the weight 3d is fixed to the other corner near the column 2, and when the column 2 is extended, It is configured not to be beaten by the wind.

  On the surface of the flag body 3, a large number of pieces 4 are stuck. As shown in FIG. 3, the reversing piece 4 is formed in a band shape, and includes a reflecting portion 4 a that reflects radar radio waves and a fixing portion 4 b to the flag body 3. The reflector 4a can be made of a material that can reflect radar radio waves, for example, a cloth in which metal foil is vapor-deposited or bonded, a plastic sheet, a sheet-like laminate in which metal foil is laminated on a cloth or plastic sheet, and the like. . The surface of the flip piece 4 may be formed with unevenness of an appropriate size by embossing, quilting, or the like, and the radar radio wave is easily reflected by the unevenness. The size and depth of the unevenness can be set to optimum values in consideration of the wavelength of the radar radio wave and the spread of the reflected radar radio wave. Further, it is preferable to color the reflecting portion 4a because it is easy to find by visual recognition. The fixing portion 4b is sewn to the flag body 3 by the sewn wire 8 as shown in FIG. It is also possible to fix the fixing portion 4b to the flag body 3 with an adhesive or the like.

  A weight 5 is attached to the lower end of the column 2. The weight 5 is formed by filling the inside of the bag 5a with sand 5b, and the total weight is set to about 1.5 kg to 2 kg.

  Above the weight 5, a floating body 6 is provided integrally with the weight 5. The floating body 6 is formed of a plastic fabric such as nylon or polypropylene, and is formed in a bag shape so that the support column 2 penetrates the center portion. The upper part 6 a of the floating body 6 is formed with a large diameter, and the lower part 6 b is formed with a diameter slightly larger than the outer diameter of the support 2. An air intake 6c for introducing air into the float 6 is attached to the float 6, and the float 6 can be expanded by supplying air from a cylinder or the like via the air intake 6c. A diver or the like can also inflate the floating body 6 by introducing air from the mouth.

  Next, a method for using the life preserver having the above configuration will be described in detail with reference to the drawings.

  A diver or the like folds the flag body 3 and wears the life-saving device 1 on a part of the body in a contracted state in which the support 2 is contracted and air is not introduced into the floating body 6, and performs diving. Moreover, if it is an angler, it will fish on a ship etc. in the state which attached the life preserver 1 of the above-mentioned state to the body.

  When it is determined that a diver or the like that has emerged from the sea has moved away from the mother ship and it is difficult to see himself / herself from the mother ship, the lifesaving device 1 is removed from the body, and the air intake 6c of the floating body 6 is removed. Then, air is introduced from the cylinder into the floating body 6 to inflate the floating body 6. The floating body 6 may be inflated by supplying air from its own mouth to the air intake portion 6c.

  Next, air is introduced from the cylinder or the like into the inside of the column 2 from the air intake port 2b of the column 2, and the column 2 is extended. As a result, the flag body 3 attached to the uppermost portion of the column 2 is turned by the wind. Here, the height from the upper end of the floating body 6 to the tip of the support column 2 is about 4 m, but the weight 5 mounted below the floating body 6 immerses nearly 1 m below the upper end of the floating body 6 in the sea. Therefore, the life preserver 1 can be maintained in a stable state on the sea.

  When the life-saving device 1 is floated on the sea in this way, a large number of repelling pieces 4 attached to the flag body 3 can be swung to a height of about 4 m above the floating body 6, so that the sea waves are high. Even in cases, it is easy to reflect radar radio waves, and a diver or the like can be easily found. Further, as shown in FIG. 2 (c), the large number of reversing pieces 4 attached to the flag body 3 are swung in the direction of the arrow by the wind, so that the radar radio wave is easily reflected, and the radar finding is easier. It becomes. Moreover, if the transflection piece 4 is colored, it will be easily found by visual recognition from a mother ship close to a diver or the like.
