Description

  The present invention relates to a bag used for preventing flooding.

  Conventionally, a bag called a sandbag has been used as a countermeasure against flooding. Sandbags are used to prevent the movement of water and earth and sand by filling soil bags with sand and sand in a cloth bag made of linen, etc. in the event of a sudden flood or earth and sand disaster, and then binding and stacking the cloth bags. In some cases, it may be difficult to obtain soil and sand, so in recent years, a so-called water pouch that can be filled with water, a so-called water pouch has been proposed.

  Patent Document 1 proposes a very simple disaster prevention water sac that uses a waterproof cloth or sheet as a substitute for water damage prevention sandbags, and is provided with a water suction port and a drainage port, and pumped with water. Has been. However, conventional water sacs including the water sacks proposed in Patent Document 1 are more versatile than sand bags because they do not have to be used by obtaining soil or sand when viewed as a single body. However, on the other hand, the shape is unstable compared to the sandbag, and it is difficult to stack a plurality of water sacs, so that it is difficult to form a strong block. In addition, there has been no structure that can be used as a life-saving device in case of sudden flood damage or earth and sand disaster.

  The present invention was developed on the basis of the above situation, and is a bag body that can easily form a strong block, and can also be used as a lifesaving device in the event of sudden water damage or landslide disaster. The purpose is to provide.

In order to solve the above-mentioned problem, the present invention is made of a waterproof material, and is arranged side by side in a lateral direction through a connecting member that can bend a plurality of bag bodies that are approximately square-shaped by pressure from the inside , Adjacent bag bodies are provided with an inlet through which gas or liquid can be injected so that the upper surface and the lower surface of the bag body are different from each other . The bag main bodies adjacent to each other are stacked upside down, and the upper and lower bag main bodies are fixed by the detachment preventing member provided on the opposite side of the connecting portion by the connecting member and the connecting member .

If it is the structure like this invention, when using a some bag main body when forming a block, since the upper and lower bag body main bodies can be fixed with a detent member and a connection member , a firm block is formed. Is easy. In addition, in the case of a structure that can inject a gas such as air and expand in a substantially square shape by pressure from the inside as in the present invention, it is possible to enclose a gas such as air in the event of a sudden flood or landslide. Because it becomes a floating body, it can be used as a lifesaving device.

(A), (B), and (C) are a front view, a side view, and a plan view showing a first embodiment of the bag of the present invention. (A) and (B) are a front view and a plan view showing a second embodiment of the bag of the present invention. (A), (B), and (C) are a plan view, a front view, and a front view when the bag body is overlapped, showing a third embodiment of the bag body of the present invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 3. 1st Embodiment of the bag body 10 of this invention consists of the bag main body 20 and the thick vinyl 30, as shown to FIG. 1 (A), (B), and (C). And the bag main body 20 and the thick vinyl 30 are integrated after integrally molding or making each as a separate member.

  The bag body 20 is made of a waterproof material including synthetic resin such as vinyl, leather, cloth, and the like, and liquid such as water and gas such as air are supplied from the inlet 21 provided on the upper surface of the bag body 20. In other words, the cap 40 can seal the opening of the injection port 21. And, when using the bag body 10 of the present invention, a liquid such as water or a gas such as air that fills about 90% of the volume in the bag body 20 is injected from the inlet 21 to expand the outer surface, The bag body 20 finally has a substantially square shape with rounded corners. From the viewpoint of stability, it is desirable that each surface of the bag body 20 has a shape that approximates a rectangle that is not a square, and is in a horizontally long state when viewed from the front.

  In addition to the injection port 21 described above, a cartilage member 22 is provided on the upper surface of the bag body 20. The cartilage member 22 is made of a sand-like elastic support material and is provided so as to surround at least the periphery of the upper surface of the bag body 20 in order to maintain the stability of the shape of the bag body 20. . Then, as shown in FIG. 1 (c), the bag body 20 may extend like a beam along the short side direction of the bag body 20 in order to prevent lateral deflection of the bag body 20. In addition, since this cartilage member 22 also serves to prevent misalignment when stacking a plurality of bags 10, there is no problem even if the cartilage member 22 is provided in a mesh shape to further increase the frictional resistance. The thickness of the cartilage member 22 is arbitrary, but considering the ease of stacking the bag 10, the opening of the injection port 21 may be thicker than the height when the cap 40 is sealed. .

  Further, on the bottom surface of the bag body 10, more specifically, on the bottom surface side of the bag body 20, a thick vinyl 30 made of a material that does not break even if it gets wet to some extent, such as a waterproof material, is provided. The thick vinyl 30 extends in the horizontal direction from the bottom surface of the bag body 10, more specifically, from each side of the bottom surface of the bag body 20, in other words, the bottom surface of the bag body 20. As a center, it is arranged in a skirt shape. As shown in FIG. 1C, the thick vinyl 30 is extended in a substantially rectangular shape from the bottom surface of the bag body 10, more specifically, from each side of the bottom surface of the bag body 20 when viewed in plan. However, the shape is not necessarily rectangular, and a shape close to a circle is not a problem. And, on the bottom surface of the thick vinyl 30, like the top surface of the bag body 20, as a fixing member to the installation position, a support that is rich in sand-granular elasticity is used when a plurality of bag bodies 10 are stacked. It is desirable to provide a cartilage member 31 made of a material. With such a configuration, the bag body 10 has high shape stability and can easily form a block by combining a plurality of bag bodies 10. When carrying the bag body 10 of the present invention, it is desirable that the thick vinyl 30 has a certain thickness so that the thick vinyl 30 can be easily gripped. As shown in FIG. 1C, there is no problem even if a through-hole 32 is formed as a handle. Moreover, it is preferable that the above-mentioned through-hole 32 has a size that allows the user's arm to pass through. By passing the arm through the through-hole 32, a floating body is formed by enclosing a gas such as air. Since it becomes easy to carry the bag body 10 and carry it, it becomes more convenient as a lifesaving device. In addition, even when a plurality of bag bodies 10 are stacked, adjacent fixing bodies 10 are fixed to each other so that the thick vinyl 30 and the side of the bag body 20 are provided with a fitting-type fixing portion or an engaging member. Absent.

  In the second embodiment of the bag body 10 of the present invention, as shown in FIGS. 2A and 2B, a plurality of bag body bodies 20 are connected. The connected bag bodies 20 are connected to each other by a communication passage or the like (not shown). From any one of the plurality of inlets 21, liquid such as water, air, or the like If the gas is injected, it is desirable that the injected material spread over all of the connected bag bodies 20. In addition, 2nd embodiment of the bag body 10 of this invention has the some inlet 21 as shown in FIG. This is arranged so that it is easy to discharge the liquid or gas accumulated inside after use, but there is no problem even if it is used when injecting liquid such as water or gas such as air. .

  The third embodiment of the bag body 10 of the present invention assumes from the beginning that a plurality of bag body 20 are connected and overlapped as shown in FIGS. 3 (a), (b), and (c). It is a thing. Then, as shown in FIG. 3A, adjacent bag bodies 20 are connected to each other by connecting members 23 in the plurality of bag bodies 20 arranged side by side in the width direction on the paper surface. As shown in FIG. 3 (a), the plurality of bag bodies 20 arranged side by side in the height direction on the paper surface are connected to each other at least by a communication passage (not shown). If a liquid such as water or a gas such as air is injected from any one of the plurality of inlets 21, the injected material spreads over all of the bag bodies 20 arranged side by side in the height direction. It is desirable that In addition, 3rd embodiment of the bag body 10 of this invention has the inlet 21 in each of the some bag main body 20 arranged in parallel by the height direction on the paper surface, as shown in FIG. . This is arranged so that it is easy to discharge the liquid or gas accumulated inside after use, but there is no problem even if it is used when injecting liquid such as water or gas such as air. . When the bag body 20 is overlapped, as shown in FIG. 3 (b), the bag body 20 located on the left side in the width direction on the paper surface, in other words, the bag body at the lowest level. The bag body 20 connected by the connecting member 23 is stacked one after the other. When superposed, as shown in FIG. 3 (c), the portions not connected by the connecting member 23 are fixed by a locking member 24, which is a metal fixing member, and is strong. Form a block. In addition, like the third embodiment of the bag body 10 of the present invention, when a plurality of bag body bodies 20 are connected and a relatively large buoyancy is expected to be obtained, in the event of a sudden flood or disaster It can also be used for bags and air mats.

  The structure of the embodiment of the present invention disclosed above is merely an example. The technical scope of the present invention is indicated by the description of the scope of claims, and includes a technical configuration that is evaluated as equivalent to the description. In addition, the material, size, hardness, and the like of the members constituting the bag body 10 are arbitrary in order to cope with various disasters, and the number of the bag body 20 that the bag body 10 has is one or more. It doesn't matter how much.
