Description

  The present invention relates to a life buoy used in the event of a flood disaster.

  Life jackets are known as means for preventing ship crews from drowning in the event of a flood. However, this life jacket needs to be worn before encountering a disaster and is not suitable for helping those who are already drowning. Life buoys are usually used to rescue those who are already drowning.

  Among life buoys, life buoys made of lightweight materials such as urethane are widely used. However, since this life buoy is large in size and requires a large area for storage, it has been difficult to mount the life buoy on a vehicle or the like having no space. In view of this, there has been devised a floating ring that can be folded and stored in a small size, such as a portable water rescue float disclosed in Utility Model Registration No. 3022755.

On the other hand, various means for confirming the location of the survivor and enabling quick rescue in the event of a flood disaster have been proposed. As such means, a life jacket with a GPS function disclosed in Japanese Patent Laid-Open No. 2001-114191, a reflector buoy for radar disclosed in Japanese Patent Laid-Open No. 2002-240776, a water rescue signal and a water rescue disclosed in Japanese Patent Laid-Open No. 2003-231494 are disclosed. There is a life-saving garment with an EL light emitter disclosed in Japanese Patent Application Laid-Open No. 2004-34954.

  However, conventional methods for confirming the presence position have a complicated structure and are often operated by a battery. For this reason, those that are difficult to fold for the structural reasons cannot be attached to a portable floating ring. Even if it can be attached to a portable floating ring, a complicated structure may be damaged by an impact during expansion. In addition, the battery-operated device may not function in the event of drifting over the sea for a long time.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a life buoy including a position checking means that can be folded small and can function for a long time without being damaged by an impact during expansion.

  A first life buoy according to the present invention includes an annular portion made of a flexible cylinder and a wing portion made of a pair of sheet-like members protruding from opposing positions on the outer periphery of the annular portion. And the surface of the wing portion is covered with a material that reflects visible light and electromagnetic waves.

  On the other hand, the second life buoy according to the present invention is provided with a gas cartridge that is automatically opened at the time of landing on the first life buoy, and is folded into a container that is expanded by expansion of the annular portion. It is housed in a state.

  The container may be formed by folding a rectangular sheet-like member in half and closing at least two sides with a hook-and-loop fastener among the other three sides excluding the crease.

  The container may be a paper bag.

  The container may include a water passage hole.

  A gas cartridge that is automatically opened at the time of landing may be provided in the first lifebuoy ring. Further, both the first and second lifebuoy rings may be provided with a blinking light that is turned on when the gas cartridge is opened in the annular portion.

  Further, both the annular portions of the first and second life buoys may have an inner diameter larger than a human torso diameter.

  According to the first lifebuoy according to the present invention, the wing part whose surface is coated with a material that reflects visible light and electromagnetic waves reflects sunlight in the daytime, and reflects electromagnetic waves regardless of day and night, It functions as an existence position confirmation means for notifying a person who is searching by video or visual observation or a person searching by radar. Further, since the wing portion is composed of a sheet-like member, it can be folded, and since it has a very simple structure, there is no possibility of being damaged by an impact during expansion. Further, since no battery is required, the battery can function for a long time (almost semipermanently). Furthermore, since the wing part protrudes from the opposing position on the outer periphery of the annular part, the floating state of the annular part can be stabilized.

  In order to improve the usability of the first life buoy, the second life buoy according to the present invention is maintained in a folded state as long as the annular portion does not expand, and further, the annular portion is left loose. Even if thrown, it will not expand until it reaches the ground. Therefore, even when a person is drowning at a remote position, the person can be thrown accurately toward the drowning person.

  The container is folded in half, and at least two sides of the other three sides except for the folds are closed with hook-and-loop fasteners, forming a structure that can be reliably deployed in use with an extremely simple structure. it can. Similarly, even if the container is a paper bag, the container is surely unfolded during use while having a simple structure. However, paper bags are advantageous in terms of cost compared to those formed of rectangular sheet-like members, but cannot be reused because they are developed by tearing. Moreover, since there is a possibility that it may unfold when not needed due to getting wet in the rain, there is an inferior storage property.

  When the container is provided with a water passage hole, water necessary for automatic opening of the gas cartridge can be quickly introduced into the container, so that the time from landing to expansion can be shortened.

  If a gas cartridge that is automatically opened at the time of landing is used, the annular portion of the first life buoy can be reliably inflated when necessary, like the second life buoy. In addition, if a flashing light that is turned on when the gas cartridge is opened is provided at the annular part of the first and second life buoys, the presence location is informed to the person who is searching by video or visual inspection even at night. And can assist the function of the wings until the end of its lifetime.

  Furthermore, if both of the annular portions of the first and second life buoys have an inner diameter larger than a human torso diameter, the user can easily grip the annular portion through the torso. , Can be prevented from drowning when exhausted.

FIG. 1 shows a specific example of the first life buoy according to the present invention, wherein (a) is a plan view and (b) is a front view.
The life buoy includes an annular portion 1 made of a nylon-pulled urethane cylinder and a wing portion 2 made of a pair of PET sheets projecting from opposing positions on the outer periphery of the annular portion 1. However, the material of the annular portion 1 and the wing portion 2 is not limited as long as it is flexible and can form a cylindrical body in an airtight manner. Good.

  An aluminum vapor deposition film is attached to the surface 2a of the wing part 2 so that visible light and electromagnetic waves are reflected. However, the material covering the surface of the wing part 2 is not limited as long as it reflects visible light and electromagnetic waves, and an optimal material may be selected according to the manufacturing process and the like.

  The dimensions of the annular portion 1 when expanded are an inner diameter D of 450 mm, an outer diameter of 750 mm, and an internal capacity of about 12 liters. Moreover, the dimension at the time of expansion of the wing | blade part 2 is 400 mm x 450 mm.

  According to this lifebuoy ring, the wing part 2 whose surface is coated with an aluminum vapor deposition film that reflects visible light and electromagnetic waves reflects sunlight in the daytime, and reflects the electromagnetic waves regardless of day and night. It functions as an existence position confirmation means for notifying a person who is searching for a person or a person who is searching by a radar. Further, since the wing part 2 is composed of a PET sheet, it can be folded, and since it has a very simple structure, there is no possibility of being damaged by an impact during expansion. Further, since no battery is required, the battery can function for a long time (almost semipermanently). Furthermore, since the wing part 2 protrudes from the opposing position on the outer periphery of the annular part 1, the floating state of the annular part 1 can be stabilized.

  Furthermore, since the inner diameter D of the annular portion 1 is larger than the human torso diameter, the user can easily grip the annular portion 1 through the torso and bend away when the physical strength is consumed. Can be prevented.

The annular part 1 is provided with a gas cartridge 3 in a part located underwater in a state of floating on the water surface. And the sealing plate of this gas cartridge 3 is controlled by the cutting device 5, and it opens automatically at the time of landing.
If it carries out like this, the annular part 1 can be expanded easily and reliably.

  A gas cartridge containing 24 g of carbon dioxide gas is employed for the gas cartridge 3, but a cartridge having a different capacity depending on the dimensions of the annular portion 1 may be employed. On the other hand, as the cutting device 5, for example, a known technique (for an inflatable lifesaving device disclosed in Japanese Patent Publication No. 3-77118) in which the movement of the urged movable member is suppressed by a flexible member that loses strength rapidly when wet. A gas charging device) can be used.

In the annular portion 1, a flashing lamp 4 that is lit by opening the gas cartridge 3 is erected at a portion that is floated on the water surface and positioned on the water.
In this way, even at night, it is possible to notify the person who is searching by video or visual observation of the location, and it is possible to assist the function of the wing until the end of its life.

  As the blinking lamp 4, for example, a known strobe light attached to a life jacket can be used. If the line is made conductive by the operation of the cutting device 5, it can be turned on simultaneously with the opening of the gas cartridge 3.

  Furthermore, an air supply / exhaust pipe 6 is attached to the annular portion 1, and the expansion degree can be adjusted as necessary at the time of use, and when it is reused after use, the gas is removed and the folding work is easily performed. Be able to. In addition, if a pair of hook_and_loop | surface fastener 7 provided in the both ends of the wing | blade part 2 is utilized, the folding operation | work which the wing | blade part 2 will face each other can be performed more efficiently.

  Furthermore, the annular portion 1 is provided with a rope ring 8 so that the rope can be attached to the ring portion 8 as required and can be easily pulled.

  The second life buoy according to the present invention is obtained by folding the life buoy and accommodating it in the container. 2 and 3 show specific examples of the second lifebuoy container according to the present invention, FIG. 2 is a front view of the container, and FIG. 3A is a rectangular shape that forms the container. FIG. 3B is a front view showing the sheet-like member in a developed state, and FIG. 3B is a rear view showing the sheet-like member in a developed state.

  The container 10 is formed by folding a rectangular sheet-like member 11 in half and closing the other three sides 13 a, 13 b, 13 c except for the crease 12 with a hook-and-loop fastener 14. And when the said annular part 1 accommodated in the state folded by the inside expand | swells, the hook_and_loop | surface fastener 14 separates and expand | deploys. The sheet-like member 11 has a long side of 560 mm and a short side of 290 mm. On the other hand, the dimensions of the container 10 are 290 mm in body height and width not including the handle 17 described later, and 50 mm in thickness when the annular part 1 and the wing part 2 are folded and accommodated.

  The annular part 1 and the wing part 2 accommodated in a folded state in the container 10 are maintained in the folded state unless the annular part 1 expands. Further, even if the annular portion 1 is thrown integrally with the container 10, it does not expand until it reaches the water. Therefore, even when a person is drowning at a remote position, the person can be thrown accurately toward the drowning person. Moreover, the container 10 has a very simple structure, but can be reliably deployed during use.

The container 10 includes a water passage hole 15 penetrating the sheet-like member 11.
If it carries out like this, since the water required for the automatic opening of the gas cartridge 3 can be rapidly introduced in the inside of the container 10, the time from landing to expansion | swelling can be shortened.

The sheet-like member 11 is further folded at the side 13 b opposite to the fold line 12, and an inlet / outlet port 16 for the annular portion 1 and the wing portion 2 is formed. And the annular part 1 and the wing | blade part 2 can be smoothly taken in / out as needed.
In addition, a handle 17 is attached to the loading / unloading port 16 so that it can be easily carried and carried.
Further, the container 10 is provided with a rope case 18 so that the rope attached to the rope ring 8 can be stored so as not to become unworn until it is used.

  In consideration of storability, the sheet-like member 11 is preferably a nylon sheet or the like that does not deform or change quality even when wet, but in order to reduce costs, the entire container 10 is made of paper. It is also possible to make it. In that case, instead of forming the sheet-like member 11 and the hook-and-loop fastener 14, a simple paper bag can be used as the container. However, the paper bag body is advantageous in terms of cost as compared with the container 10 formed of a sheet-like member 10 such as a nylon sheet, but cannot be reused because it is developed by tearing. Moreover, since there is a possibility that it may unfold when not needed due to getting wet in the rain, there is an inferior storage property.

  In addition, the container for the second lifebuoy ring according to the present invention does not have to be in a bag shape, and may have a box shape or other shapes depending on the storage situation.

The specific example of the lifebuoy ring concerning this invention is shown, (a) is a top view, (b) is a front view. It is a front view which shows the specific example of the container of the 2nd life buoyancy ring concerning this invention. The rectangular sheet | seat member which forms the container is shown expanded, (a) is a front view, (b) is a rear view.
