Description

[Technical field]

[0001] The present invention is directed to a method for protecting various objects, such as electrical appliances, bedding, household goods, office equipment, agricultural machinery, machine tools, and various vehicles, in the event of a tsunami or flood. Immerse Flood prevention pads to protect against water and spills To Regarding. [Background technology]

[0002] Conventionally, when a house is flooded (above the floor) or a house collapses due to a tsunami or flood caused by a typhoon, torrential rain, earthquake, etc., the household goods may be submerged in water or flow out to the outside, causing the household goods to become soiled or damaged, becoming unusable, or going missing. For example, Patent Document 1 proposes a sealed reinforced bag that protects bedding, clothes, and other household goods from damage such as getting wet or collapsing due to a landslide when the floor is flooded in a flood, etc. In addition, Patent Document 2 proposes a flood prevention bag for automobiles that prevents vehicles from being submerged in water, in which an automobile is placed in the center of a bag with a box-shaped waterproof cloth attached under the air bag, the air bag is inflated with the automobile's exhaust gas, and the air bag rises as the surrounding water level rises, protecting the automobile from flooding. Patent Document 3 proposes a floating mat for automobiles, which is composed of at least a bag-shaped foldable mat body for supporting and floating the underfloor of an automobile, an inlet pipe for introducing gas into the mat body, and an exhaust attachment for attaching the end of the inlet pipe to the exhaust pipe of a muffler, and the mat body is composed of at least a central mat part and side mat parts disposed and fixed on both sides of the central mat part. Patent Document 4 proposes a water surface flotation device for a vehicle, which includes a float, a water ingress detection unit for detecting water ingress into the passenger compartment, a control unit for issuing a control signal according to a detection signal from the water ingress detection unit, and a gas supply unit for supplying gas to the float according to a control signal from the control unit. Patent document 5 proposes a waterproof cover for automobiles which comprises a waterproof bottom pad, hollow side bars which communicate with each other around the periphery of the waterproof bottom pad, waterproof air filling holes at one end of the side bars, and a waterproof cover body on one side of the waterproof bottom pad, with corresponding waterproof fasteners installed on the waterproof cover body and the waterproof bottom pad, and after the automobile is wrapped in the waterproof cover body, the waterproof cover body and the waterproof bottom pad are fastened together using the waterproof fastener.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-29172 [Patent Document 2] Utility Model Registration No. 3100090 [Patent Document 3] JP 2016-20191 A [Patent Document 4] JP 2016-132365 A [Patent Document 5] Utility Model Registration No. 3179545 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the sealed reinforced bag of Patent Document 1 is composed of an inner bag and an outer bag, each of which is watertight and airtight, and the inner bag, which has been sealed after storing various items, is placed in the outer bag, and an appropriate space is created between the inner bag and the outer bag, and the outer bag is sealed. In the event of a collapsed object falling onto the sealed reinforced bag, the air pressure between the inner bag and the outer bag protects the items stored in the inner bag from impact. Therefore, the inner bag and the outer bag must be sealed separately, which makes it time-consuming to store items and makes the work less efficient. Even if an appropriate space is created between the inner bag and the outer bag and the outer bag is sealed, if the inner bag is not fixed, it may move or fall inside the outer bag due to external impact or vibration, causing the posture to become unstable, and the items inside may be damaged. In particular, if multiple inner bags are stored inside the outer bag, the space cannot be maintained, and the inner bags may collide with each other, damaging the items inside. In response to this, Patent Document 1 describes fixing the inner bag with adhesive tape and creating a space with cushioning material to prevent damage to the items caused by impact between the inner bags or external impacts, but it is difficult to reliably fix the inner bag with adhesive tape alone, and the specific configuration and method of creating a space with cushioning material are unclear. In addition, these operations are time-consuming, so there is a problem that they lack the ability to respond to emergencies. In addition, if air leaks out when sealing the inner bag and outer bag, the internal air pressure cannot be maintained and the inner bag and outer bag will collapse, making it impossible to protect the items from impact. Furthermore, large and heavy objects such as machine tools and various vehicles are not assumed as objects to be protected, and no measures have been considered to prevent the sealed reinforced bag containing the object to be protected from drifting, so there is a problem that it lacks practicality.

[0005] In Patent Document 2 and Patent Document 3, although the vehicle can be made to float on the water to prevent it from sinking, there is a risk that the vehicle may be swept away by the water together with the air bag or the mat body and drift away, since there is no means for anchoring the air bag and the mat body to surrounding fixed objects (for example, a pillar, a utility pole, or a large tree, etc.). Furthermore, when floating on the water, the vehicle is likely to become unstable, and there is a possibility that the vehicle may be capsized and damaged by a strong water current, or that the air bag and the mat body may be damaged and become flooded or submerged, resulting in a problem of lack of safety and reliability. In Patent Document 4, the float is housed inside the vehicle and the vehicle can be maintained in a semi-submerged state (unsinkable state), but there is no means for anchoring the vehicle, so there is a risk that the vehicle may be swept away by the water and drift away. Furthermore, there is a problem of lack of safety, since there is nothing to protect the periphery of the vehicle, and there is a possibility that drifting objects, etc. may collide with the vehicle and damage it. In Patent Document 5, a fitting ring is attached to the corner of the waterproof bottom pad, and a wire body is passed through the fitting ring and tied to a surrounding fixed object to prevent drifting. However, when the weight of the automobile (vehicle) is concentrated on the wire body due to a water current, there is a risk that the wire body will break, the fitting ring will be damaged, or the connection between the fitting ring and the waterproof bottom pad will tear. As a result, the automobile waterproof cover may drift with the automobile inside it, or water may penetrate into the interior of the automobile waterproof cover and cause it to become submerged, resulting in problems of a lack of durability and safety and insufficient measures to prevent drifting and submersion. The present invention has been made in view of the above circumstances, and is directed to a method for protecting various objects to be protected, such as electrical appliances, bedding, household goods, office equipment, agricultural machinery, machine tools, and various vehicles, in the event of a tsunami or flood. Immerse The object of the present invention is to provide a highly practical flood prevention pack that can reliably protect against flood damage such as water and spills.

[0026] Next, with reference to the attached drawings, an embodiment of the present invention will be described for better understanding of the present invention. Hereinafter, a water ingress prevention pack 10 and a water ingress prevention method according to one embodiment of the present invention will be described with reference to Figs. The flood prevention pack 10 and the flood prevention method are intended to protect various protected objects 11, such as electrical appliances, bedding, household goods, office equipment, agricultural machinery, machine tools, and various vehicles, from flood damage such as inundation and runoff by packaging them in a watertight and airtight manner in the event of a tsunami, flood, or the like.

[0027] The water ingress prevention pack 10 is made of a waterproof material and has a hollow box shape (here, rectangular parallelepiped shape), has an opening / closing part 13 that can be sealed by a waterproof fastener 12, and is provided with a storage body 15 that stores an object to be protected 11 and is fastened to surrounding fixed structures (here, pillars) 14a, 14b. The storage body 15 has a bottom 17 and a peripheral wall part 18 that surrounds the bottom 17, and an opening 19 is formed on the upper surface side of the peripheral wall part 18. In this embodiment, the storage body 15 is structured such that the opening 19 is covered by the opening / closing part 13, and the waterproof fastener 12 is attached between the periphery of the opening 19 and the outer periphery of the opening / closing part 13. The waterproof fastener 12 is attached continuously in a substantially U-shape along the peripheral wall part 18 at a position lower than the upper surface of the peripheral wall part 18, so that the operation of the waterproof fastener 12 becomes smooth and opening / closing work can be easily performed. Furthermore, since the opening / closing portion 13 is extended onto the upper edge of one face (one side face) of the peripheral wall portion 18 and is formed continuously with the peripheral wall portion 18, the opening / closing portion 13 will not get lost, there is no need to align the opening 19 with the opening / closing portion 13, and the opening 19 can be closed instantly.

[0028] With the above configuration, the water ingress prevention pack 10 can pack the object to be protected 11 in a watertight and airtight manner, but the shape, number and arrangement of the opening and opening / closing parts can be selected as appropriate. For example, in addition to a structure in which an opening is formed in a part of the peripheral wall and covered with an opening / closing part, or a structure in which an opening is formed across the upper surface of the container to a part of the peripheral wall and covered with an opening / closing part, a structure in which the peripheral wall is divided into a plurality of faces, each divided face serves as an opening / closing part, and adjacent faces are connected with a waterproof fastener may also be used.

[0029] As the waterproof material forming the flood prevention pack 10 (storage body 15), it is preferable to use a fabric having the same robustness and durability as that of, for example, a rubber boat, an air tent for disaster relief, or a fire-resistant protective suit. In particular, the fabric of a rubber boat used on water is suitable because it is difficult to tear and has excellent watertightness. Specifically, a rubber-coated fabric is preferably used in which multiple layers of rubber such as chlorosulfonated polyethylene rubber, ethylene propylene diene rubber, chloroprene rubber, or natural rubber are bonded to a synthetic fiber base fabric such as polyamide or polyester. When polyamide is used as the base fabric, it is lightweight and has excellent flexibility and elasticity, and when polyester is used, it is hard, highly rigid, has little elasticity, and has excellent durability. The combination and number of layers of rubber to be bonded to the base fabric can be appropriately selected. Also, instead of rubber, a fabric in which vinyl chloride resin is bonded to the base fabric may be used, in which case it can be easily processed, can be manufactured at low cost, and has excellent abrasion resistance. It is preferable that at least one surface of the peripheral wall 18 and the opening / closing portion 13 are integrally formed, but they may be bonded together by welding or gluing to ensure airtightness and watertightness. Even if there are seams between the bottom of the container and the peripheral wall and between the peripheral walls, they can be bonded together by welding or gluing to ensure airtightness and watertightness. In this case, the number and locations of the seams can be selected as appropriate. The seams can also be connected by a waterproof fastener.

[0030] 1, 2 and 5, first and second binding member insertion portions 23, 24 are formed in the center of the height direction of a front wall (part of the peripheral wall portion 18) 20 on one side and a rear wall (part of the peripheral wall portion 18) 21 on the other side in the longitudinal direction of the storage body 15 formed in a rectangular shape in a plan view. Then, both ends of a first binding member 25a inserted into the first binding member insertion portion 23 and crossing the surface of the front wall 20 are fastened to a fixed structure 14a located behind the rear wall 21, and both ends of a second binding member 25b inserted into the second binding member insertion portion 24 and crossing the surface of the rear wall 21 are fastened to a fixed structure 14b located in front of the front wall 20. As a result, even if a force is applied to move the storage body 15 to one side (front wall 20 side) in the longitudinal direction or to the other side (rear wall 21 side), no load is applied to the first and second bundling member insertion parts 23, 24, and damage to the first and second bundling member insertion parts 23, 24 or the storage body 15 is prevented, and the storage body 15 can be firmly fixed by surrounding the outer periphery of the storage body 15 with the first and second bundling members 25a, 25b. As a result, the storage body 15 can be effectively prevented from moving, tilting, rotating, etc., and can be maintained in a stable position to protect the object to be protected 11. As the first and second bundling members 25a, 25b, a string or a rope is preferably used, but a wire or a chain may be used depending on the type of the object to be protected 11.

[0031] In this embodiment, the first and second binding member insertion parts 23, 24 are arranged in series in the width direction of the front wall 20 and the rear wall 21, three each, but the number of the first and second binding member insertion parts and the arrangement intervals thereof can be selected as appropriate. In this embodiment, the first and second binding member insertion parts 23, 24 are formed cylindrically to increase their strength, but the diameter and length thereof can be selected as appropriate. The first and second binding member insertion parts are only required to be able to insert the first and second binding members, and the shape thereof is not limited to a cylindrical shape and can be selected as appropriate, for example, a semi-cylindrical shape. The first and second binding member insertion parts 23, 24 are fixed to the storage body 15 by welding or adhesion, so that the material thereof is preferably the same as the material of the storage body 15, but may be different, and may not be waterproof, and may be a general cloth or synthetic resin.

[0032] As shown in Figs. 4 and 5, the water ingress prevention pack 10 includes a buffer member 26 that detachably covers the outer periphery of the object to be protected 11. The buffer member 26 can be fixed by wrapping a fixing band 27 made of rubber, cloth, or the like around the buffer member 26 that covers the outer periphery of the object to be protected 11 and binding the ends together, or by joining them with a hook-and-loop fastener or the like. The outer shape of the object to be protected 11, the outer periphery of which is covered with the buffer member 26, is shaped into a rectangular or square shape in a plan view, so that the convex and concave parts on the outer periphery of the object to be protected 11 are covered with the buffer member 26, and damage to the object to be protected 11 (mainly the convex parts) can be prevented. In addition, the peripheral wall part 18 of the container 15 is not broken by the convex parts of the object to be protected 11, so that water ingress into the container 15 can be prevented, and the object to be protected 11 can be reliably protected. The dimensions, number, and arrangement of the fixing bands can be selected as appropriate.

[0033] As the cushioning member 26, it is preferable to use a member (for example, an air mat) that is formed in a hollow bag shape and can be filled with gas (air, nitrogen, carbon dioxide, etc.) before use. The cushioning member 26 may be filled with gas in advance and then wrapped around the outer periphery of the object to be protected 11, or the cushioning member 26 in a collapsed state after the gas has been removed may be wrapped around the outer periphery of the object to be protected 11 and then filled with gas. In addition, if the cushioning member 26 is wrapped around the outer periphery of the object to be protected 11 while simultaneously filling with gas, the operation time can be shortened. Note that each surface of the object to be protected does not necessarily need to be covered with one cushioning member. For example, a plurality of cushioning members may be arranged side by side along the longitudinal direction of the object to be protected, or a plurality of cushioning members may be arranged overlapping each other, and the total thickness of the cushioning member can be selected as appropriate.

[0034] The cushioning member 26 is preferably formed in a square or rectangular plate shape according to the dimensions (length, width, and height) of the object to be protected 11, but it is also possible to use one having a plurality of (here, five) air chambers 29, such as a modified cushioning member 28 shown in FIG. 6. In the cushioning member 28 having a plurality of divided air chambers 29, even if some of the air chambers 29 are damaged and the gas inside leaks, the gas can be prevented from leaking from the other air chambers 29, and the function of the cushioning member 28 can be maintained. In addition, if the number of air chambers is increased to make the cushioning member longer, instead of disposing separate cushioning members 26 on the outer periphery of the object to be protected 11 as shown in FIG. 4, one cushioning member can be folded and wrapped around the outer periphery of the object to be protected 11. The cross-sectional shape of the air chamber is preferably a circular shape other than the semicircular shape shown in FIG. 6, but is not limited thereto and can be selected appropriately.

[0035] Cushioning materials can also be used as the shock-absorbing material, and in this case, sheet-like polyurethane (sponge) or the like can be used as is, or can be packed in a bag made of cloth or synthetic resin. Incidentally, bubble cushioning material can also be used as the shock-absorbing material, but in this case, it is preferable to use multiple sheets stacked together. The different types of shock-absorbing materials described above can be used alone, or multiple types can be combined (stacked) for use. Also, instead of preparing these dedicated shock-absorbing materials, blankets, futons, etc. can be used as simple shock-absorbing materials by covering the periphery of the object to be protected, or dedicated shock-absorbing materials can be used in combination with simple shock-absorbing materials.

[0036] In this embodiment, as shown in FIG. 5, the upper surface of the object to be protected 11 is covered with an upper buffer member 30 to reduce the impact from the upper surface side of the container 15 due to a collision with a falling or toppling object. The upper buffer member 30 may be simply placed on the upper surface of the object to be protected 11, or may be fixed to the object to be protected 11 or the buffer member 26 as necessary. The upper buffer member may be omitted. In addition, when the container 15 containing the object to be protected 11 floats on water due to buoyancy, the entire upper surface of the bottom 17 may be covered with a bottom buffer member to reduce the impact from the bottom 17 side due to a collision with a drifting object. The bottom buffer member may or may not be fixed to the bottom. The material and structure of the upper buffer member and the bottom buffer member are the same as those of the buffer member, but they do not all need to be of the same type, and different types may be used depending on the installation location, etc.

[0037] A method for preventing water ingress will be described based on the method for using the water ingress prevention pack 10 configured as above. First, as shown in Fig. 3, the opening / closing part 13 of the housing 15 is opened, and the housing 15 is placed in a desired position with the peripheral wall part 18 of the housing 15 being crushed in the height direction. Then, the object to be protected 11 is placed (moved) on the upper surface of the bottom part 17 of the housing 15 (this is the process of placing the object to be protected). Next, as shown in Fig. 4, the outer periphery of the object to be protected 11 is detachably covered with a cushioning member 26 and fixed with a fixing band 27. As described above, the cushioning member 26 is formed in a hollow bag shape, and is filled with gas when in use. The outer shape of the object to be protected 11 whose outer periphery is covered with the cushioning member 26 is shaped into a rectangular shape in a plan view. The upper surface of the object to be protected 11 is covered with an upper cushioning member 28 (this is the cushioning member attachment process). Next, as shown in FIG. 5, the peripheral wall portion 18 of the storage body 15 is lifted upward and the opening / closing portion 13 is sealed with a waterproof fastener 12, thereby allowing the object to be protected 11 to be stored inside the storage body 15 (this is the process of storing the object to be protected).

[0038] Next, as shown in Figures 1 and 2, for a storage body 15 which is formed in a rectangular shape when viewed in a plane and has first and second binding member insertion portions 23, 24 formed respectively in the heightwise center of a front wall 20 on one side and a rear wall 21 on the other side in the longitudinal direction, a first binding member 25a is inserted into the first binding member insertion portion 23, and both ends of the first binding member 25a crossing the surface of the front wall 20 are connected to a fixed structure 14a located behind the rear wall 21, and a second binding member 25b is inserted into the second binding member insertion portion 24, and both ends of the second binding member 25b crossing the surface of the rear wall 21 are connected to a fixed structure 14b located in front of the front wall 20. At this time, it is preferable that the height at which both ends of the first and second binding members 25a, 25b are fastened to the fixed structures 14a, 14b is lower than the height of the first and second binding member insertion parts 23, 24, and that the first and second binding members 25a, 25b are slackened from the first and second binding member insertion parts 23, 24 to the fixed structures 14a, 14b. This makes it possible to reduce the load applied to the first and second binding members 25a, 25b when a force is applied to move the water entry prevention pack 10 (storage body 15) due to buoyancy or water current (above, storage body fastening process).

[0039] According to the flood prevention pack 10 and flood prevention method configured as above, when a tsunami or flood occurs, various objects to be protected 11 can be stored inside the flood prevention pack 10 (storage body 15) installed indoors or outdoors, and the objects to be protected 11 can be protected from flooding and runoff. Therefore, the victims do not need to move the objects to be protected 11 to a safe place such as a high place before evacuation or take them out when evacuating, and can evacuate quickly, and can protect their property while ensuring their physical safety. In particular, when the objects to be protected 11 are heavy objects that do not float on water, such as agricultural machinery, machine tools, or large special vehicles, the objects to be protected 11 stored in the storage body 15 can be protected from flooding while the storage body 15 is submerged. Then, after the tsunami or flood subsides, the objects to be protected 11 can be used immediately by removing them from the storage body 15, and the cost burden on the victims for repairs and new purchases can be reduced. In addition, the labor and expenditure required for supporting the lives of the victims can be significantly reduced. The dimensions (length, width, and height) of the storage body 15 can be appropriately selected according to the dimensions of the object 11 to be stored. For example, for home use, a size of about 2 m in length, 1 m in width, and 1 m in height can be used to store electrical appliances such as televisions, household goods, tatami mats, carpets, futons, etc., and for business or government use, a size of about 2 to 5 m on each side can be used to store office equipment, agricultural machinery, machine tools, etc., or a length of about 5 to 10 m can be used to store large special vehicles such as police cars, fire engines, tank trucks, and vacuum trucks.

[0040] Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations described in the above embodiments. Patents It is intended that other embodiments and modifications be contemplated within the scope of the appended claims. for example , protection The object to be protected is not particularly limited as long as it can be stored in the storage body, and in addition to the above-mentioned objects, for example, safes, motorcycles, etc. can also be protected. Also, an external buffer member can be attached to the outside of the container (for example, the lower periphery of the peripheral wall portion constituting the container). The material and structure of the external buffer member can be the same as those of the buffer member described above, and can reduce the impact when the container collides with drifting objects and surrounding structures. The external buffer member can prevent drifting objects from colliding directly with the container, thereby suppressing damage to the container, and can effectively prevent the protected object stored in the container from getting wet and broken. In particular, when the external buffer member is formed in a hollow bag shape and has a structure filled with gas, when the water level rises due to a flood or the like, the external buffer member can generate buoyancy to make the container float on the water in a stable position. The number, shape, and arrangement of the external buffer members can be appropriately selected. For example, in addition to attaching one external buffer member formed in a ring shape so as to surround the outer periphery of the container, four external buffer members formed in a rod shape can be attached individually to the lower sides of the peripheral walls, or an external buffer member formed in a flat plate shape can be used to cover the entire bottom surface. In addition, damage to the storage body can be effectively prevented by attaching an external cushioning member to the upper surface of the storage body to reduce the impact of collision with falling objects, etc., or by attaching an external cushioning member to the periphery of the upper surface and / or the surface or periphery of each peripheral wall portion of the storage body to reduce the impact of collision with falling objects, drifting objects, surrounding structures, etc.

[0041] Basically, even if the entire waterproof pack (storage body) is submerged in water, water will not enter the interior of the storage body, and the protected object can be protected from flood damage. However, if the storage body (bottom, peripheral wall, and opening and closing part) or the waterproof fastener is damaged, water will enter the storage body. Therefore, the risk of water ingress can be reduced by floating the storage body on water. In this case, by making the binding member that connects the storage body to the surrounding fixed structures longer in advance (for example, about 2 to 5 m longer), the storage body can be floated as the water level rises. In addition, when binding the end of the binding member to the pillar, a gap can be provided in advance between the binding part of the binding member and the pillar so that the binding part can move (slide) along the height direction of the pillar. Alternatively, a binding material unwinding device equipped with a reel that can rotate freely in the unwinding direction of the binding material can be fixed to a pillar or the like, and the other end of the binding material can be wound around the reel. When the storage body rises along with the water level and the binding material is pulled, the binding material can be automatically unwound. [Industrial Applicability]
