Description

Technical Field

[0001] This invention relates to a simple flood shelter for emergency refuge during floods such as tsunamis or floods. Background Technology

[0002] Japan is an earthquake-prone country, and a major earthquake is expected in the near future. Therefore, preparations need to be made for large tsunamis that may result from such earthquakes. Furthermore, preparations are not limited to earthquakes; they also need to be made in areas prone to flooding and other water-related disasters.

[0003] For example, Patent Document 1 discloses a portable flood shelter that can be compactly stored during normal times and instantly forms a refuge living space with walls in a roughly cylindrical shape made of air bags that can absorb impacts during floods such as tsunamis, allowing the shelter to drift while waiting for rescue.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2017-171265 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] In the portable flood shelter described in Patent Document 1, a storage section located at the bottom of the shelter houses heavy objects such as a high-pressure gas cylinder for instantaneous inflation of the gas bag and a starting device, thereby lowering the overall center of gravity of the shelter and creating a structure that maintains positive resilience on the water surface. Therefore, the shelter in Patent Document 1 has a structure that allows entry and exit relative to the living space by opening and closing a cover located at the top of the shelter.

[0009] However, with a storage section at the bottom of the shelter to house heavy items such as high-pressure gas cylinders and starting devices, the weight of the portable shelter becomes relatively heavy, and the cost of the shelter also increases due to the installation of high-pressure gas cylinders and starting devices.

[0010] Furthermore, in the turbulent currents of a tsunami or flood, or amidst the rubble it has swept away, it is difficult to maintain the shelter's stable position. One can fully imagine the shelter overturning or flipping over. In an overturned state, it is impossible to open the cover located at the top of the shelter, making it difficult to assess the external situation, escape from the shelter, or bring air into the shelter.

[0011] Furthermore, if the refugee is secured in the shelter by a safety belt installed on the base of the shelter with the premise of maintaining a stable posture, the refugee will be unable to take appropriate action in the event of the shelter overturning or flipping over, and may even be in a dangerous situation.

[0012] One of the objectives of this invention is to provide a simple shelter for flood refuge, which can further improve the safety of refugees even in the torrents of tsunamis or floods or in the rubble washed away by them.

[0013] Another object of the present invention is to provide a simple shelter for flood refuge that is lighter and therefore more portable, compact when stored and kept, and lower in cost.

[0014] Methods for solving problems

[0015] The simplified flood shelter of the present invention is characterized by comprising: a generally cylindrical floating body, wherein multiple hollow, donut-shaped floats, each having a hollow shape, are stacked vertically by injecting gas into the body through a gas injection valve, and adjacent floats in the vertical direction are connected to each other; and

[0016] Two partition plates are respectively disposed on the inner periphery of the uppermost and lowermost floats among the plurality of floats.

[0017] The inner circumferential surface of the floating body and the two partition plates form a closed containment space that prevents water from entering from the outside and accommodates the refugees.

[0018] Each of the two partition walls is equipped with a door for refugees to enter and exit the containment space.

[0019] By installing doors on both sides of the partition panels of the floats located at the top and bottom, even if the shelter flips upside down and one partition panel is submerged, one can still monitor the outside situation or escape from the shelter through the door on the other partition panel.

[0020] Preferably, the simple refuge for flood evacuation is equipped with a safety belt consisting of two straps extending between the two partition panels and arranged side by side, and the refugee's body is positioned between the inner circumference of the floating body and the two straps to prevent the refugee from falling.

[0021] According to this structure, refugees can prevent falling simply by entering between the two straps and the inner circumference of the floating body, without any other operation. Refugees also do not need to unfasten their safety harnesses when escaping out of the shelter.

[0022] More preferably, air holes are formed in each of the two partition walls for drawing air into the receiving space from the outside.

[0023] The simple shelter for flood refuge also has a sealing plug, which can be manually inserted or removed relative to the air hole.

[0024] By inserting sealing plugs into the air holes located on the two partition plates, water intrusion can be reliably prevented. If air needs to be introduced, it can be easily handled by manually pulling out the sealing plug from the air hole on the side that is not submerged.

[0025] More preferably, the doors of the two partition panels may each have windows made of transparent material that allow for visual observation of the outside.

[0026] By installing windows in the doors of the two partition panels, the external situation can be monitored without opening the doors even if the shelter is flipped upside down.

[0027] Invention Effects

[0028] According to the present invention, a simple shelter for flood refuge is provided, which can improve the safety of refugees even in the torrents of tsunamis or floods or in the rubble washed away by them.

[0029] In addition, according to the present invention, a simple refuge for flood evacuation is provided, which is lightweight and therefore has excellent portability, is compact in storage, and has low cost. Attached Figure Description

[0042] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0043] Figures 1-4 The basic structure of a simple flood shelter (hereinafter referred to as a shelter) 1 according to one embodiment of the present invention is shown.

[0044] like Figures 1-4 As shown, the shelter 1 includes: a generally cylindrical floating body 10 composed of multiple (4) floats 10a to 10d stacked in the vertical direction; and partition plates 20, 20 respectively disposed on the inner periphery of the uppermost float 10a and the lowermost float 10d. The inner periphery of the floating body 10 and the two partition plates 20, 20 form a closed containment space SP that prevents water from entering from the outside and contains the refugee EH.

[0045] The multiple floats 10a to 10d that constitute the floating body 10 are connected to each other in the vertical direction.

[0046] The partition plates 20 and 20 are formed in the shape of circular plates, and their outer periphery is connected to the inner periphery of the uppermost float 10a and the lowermost float 10d.

[0047] Multiple floats 10a to 10d are formed of, for example, rubber material and have the same structure as a tire inner tube. Gas injection valves 11 are provided on the outer periphery of each float 10a to 10d. When air or other gas is injected into the interior of the floats 10a to 10d through these gas injection valves 11, the floats 10a to 10d will... Figures 1-4 The shape shown is a hollow donut.

[0048] The partition plate 20 consists of a generally annular fixing part 22 fixed to the inner peripheral surface of the float 10a or float 10d, and a door 24 for opening and closing the entrance 22a formed in the fixing part 22.

[0049] The fixing part 22 and the door 24 are formed of resin such as polyester. In addition, the detailed structure of the partition plate 20 will be described later.

[0050] Door 24 is connected to fixed part 22 by hinge 25, and door 24 can be opened to the outside. As described later, door 24 has window 26 and air hole 28 for taking in air into the receiving space SP.

[0051] Figure 5 An example of the connection method between floats 10a and 10d is shown.

[0052] On the outer peripheral surfaces of adjacent floats 10a and 10b in the vertical direction, fabric components fb are locally adhered in the circumferential direction using adhesive. The fabric components fb are made of materials such as chlorosulfonated polyethylene (CSM) or polyvinyl chloride (PVC), and the parts of the fabric components fb in contact with each other, as shown in region R1, are joined by stitching. This connects floats 10a and 10b, preventing water from seeping in from the connection point. Other floats are connected in the same way.

[0053] In addition, the connection between the fixing part 22 of the partition plate 20 and the floats 10a and 10d can also be achieved by using the fabric part fb to connect them by adhesive bonding.

[0054] Figure 6A and Figure 6B An example of the construction of the partition plate 20 is shown.

[0055] like Figure 6A and Figure 6B As shown, a recess 22c is formed on the upper surface of the fixing part 22 of the partition plate 20, and a groove 22b surrounding the entrance 22a is formed on the bottom surface of the recess 22c.

[0056] A sealing member SL is provided on the lower surface of the door 24. When the door 24 is closed, the sealing member SL is inserted into the groove 22b of the fixing part 22, thereby sealing the door 24 and the entrance / exit 22a. Figure 6AAs shown, the door 24 is embedded in the recess 22c when the entrance 22a is closed.

[0057] A transparent resin window 26 is embedded in the door 24, through which light L enters from the outside. That is, light L enters the containment space SP of the shelter 1, and the refugees in the containment space SP can observe the external situation through the window 26.

[0058] In addition, in this embodiment, a window 26 is provided in the door 24, but the door 24 may be made of a transparent material instead of a window 26.

[0059] Handles 29 are provided on both sides of the door 24 for gripping when opening and closing the door 24.

[0060] A towing hook hole 30 is provided on the upper surface of the fixing part 22 of the partition plate 20. The towing hook hole 30 is used when towing the drifting refuge 1 by boat or lifting it by helicopter.

[0061] A handle 31 is provided on the lower surface of the fixing part 22 of the partition panel 20. The handle 31 is provided for refugees in the containment space SP to grip.

[0062] In addition, the location and number of towing hook holes 30 and handles 31 can be changed appropriately.

[0063] A locking mechanism 40 is provided on the lower surface of the door 24. The locking mechanism 40 is provided to lock the door 24 so that the door 24, which closes the entrance / exit 22a, cannot be opened. The locking mechanism 40 includes: an operating lever 41 supported on a support member 44 so as to be rotatable about an axis 44 provided on the door 24; and a locking member 42 provided at the front end of the operating lever 41. The locking mechanism 40... Figure 6A In the indicated state, the locking member 42 is engaged with the lower end face 22d of the fixing part 22, and the door 24 is locked. This can be achieved by rotating the operating lever 41. Figure 6C As shown, the locking state between the locking member 42 and the lower end face 22d of the fixing part 22 is released, thereby unlocking the device. By achieving this state, as shown... Figure 6B As shown, door 24 can be opened.

[0064] In addition, a thin metal plate made of stainless steel or the like may be provided at the part of the lower surface 22d of the door 24 that contacts the locking member 42 of the locking mechanism 40 in order to prevent wear on the lower surface 22d of the door 24.

[0065] The locking mechanism 40 is located on both the upper and lower doors 24. There is a possibility that an evacuee, EH, might accidentally touch the operating lever 41 of the lower locking mechanism 40, thereby releasing the locking mechanism 40 and causing the door 24 to open unintentionally. To prevent this from happening, a safety mechanism such as a stop made of protrusions can be installed on the door 24 to prevent the locking component 42 from moving before a relatively large force is applied to the operating lever 41.

[0066] Figure 7 An air hole 28 formed in door 24 and a sealing plug 50 for sealing the air hole 28 are shown. The sealing plug 50 is connected to the lower surface of door 24 by chain 51. The air hole 28 is formed as a tapered hole tapering at the front end, such as... Figure 7 As shown in (a), by inserting the sealing plug 50, which is formed into a cone shape tapering at the front end, into the air hole 28, water intrusion can be reliably prevented. In the event that air needs to be drawn into the containment space SP of the shelter 1, the sealing plug 50 is manually removed from the air hole 28 of the door 24 on the unflooded side of the two doors 24, as shown. Figure 7 As shown in (b), air can be drawn in through the air hole 28.

[0067] In addition, in this embodiment, the air hole 28 is provided on the door 24, but it is not limited to this and can also be provided on the fixing part 22 of the two partition plates 20 respectively.

[0068] Figure 8A The safety belt 101 is shown to improve the safety of refugee EH who is taking refuge in the containment space SP of refugee 1.

[0069] The seat belt 101 consists of two flexible straps 101a and 101b, which extend side-by-side and are separated from each other between two upper and lower partition plates 20. One end of each strap 101a and 101b is fixed to the fixing part 22 of the upper partition plate 20, and the other end of each strap 101a and 101b is fixed to the fixing part 22 of the lower partition plate 20.

[0070] like Figure 8A As shown, the refugee EH positions their body between the inner circumference of the float 10 and the two straps 101a and 101b, and either hugs the straps 101a and 101b from the outside or holds them with both hands. This prevents them from falling within the containment space SP due to the shaking of the shelter 1. The refugee EH does not need to perform any special operations, and even when escaping out of the shelter, it is not necessary to unfasten the seatbelt 101.

[0071] like Figure 8BAs shown, the safety belt 101 is preferably installed in multiple locations (two locations). Thus, the evacuee EH can select the safety belt 101 located in an easily accessible position according to the situation.

[0072] Figure 9 The diagram roughly illustrates the external appearance of Shelter 1 in its current state of preservation. For example... Figure 9 As shown, with each float 10a-10d unfilled with gas, the floats 10a-10d are stacked flat, giving the shelter 1 a roughly circular plate shape. Since the shelter 1 does not contain heavy objects such as high-pressure gas cylinders, it is very light and compact in its stored state. Therefore, a large storage space is not required, making it easy to transport.

[0073] When storing shelter 1, it is preferable to store it together with equipment such as foot pumps, hand pumps, conduction pumps, and air compressors that inject filling gas into each float 10a to 10d.

[0074] When a tsunami or flood is detected, the refugees move shelter 1 from its storage location to a suitable location, where they use the aforementioned pumps or air compressors to fill the floats 10a to 10d with gas, causing the floats 10a to 10d to expand.

[0075] The refugee opens one of the two doors 24 and takes refuge in the containment space SP. Since there are doors 24 on the upper and lower partitions 20, 20 of the shelter 1, even if one partition 20 is flooded, the external situation can be monitored through the door 24 on the other partition 20. In addition, the refugee can escape from the shelter 1 by opening either of the two doors 24, depending on the situation.

[0076] The shelter 1 is equipped with gas injection valves 11 on each of the multiple floats 10a to 10d. The gas inside is independent, so even if any float breaks and the gas escapes, the remaining floats can keep the floating body 10 floating on the water surface, thus preventing the shelter 1 from being completely submerged.

[0077] The embodiments of the present invention have been described in detail above, but the present invention is not limited to this specific embodiment. Various modifications and alterations can be made within the scope of the spirit of the present invention as set forth in the claims.
