Description

Technical Field

[0001] This invention relates to a simple flood shelter for emergency refuge during tsunamis, floods, and other water disasters. Background Technology

[0002] Japan needs to prepare for massive tsunamis that may follow a major earthquake. Furthermore, preparations should not be limited to earthquakes; they should also be made in advance in areas prone to flooding and other water-related disasters.

[0003] For example, Patent Document 1 discloses a box-shaped shelter using a container made of hexahedrons. This box-shaped shelter has an entrance / exit formed on one side of the container made of hexahedrons, and is equipped with a door for opening and closing. Additionally, a hatch is provided at the top of the container of this box-shaped shelter.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2015-38309 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] However, the box-shaped shelter in Patent Document 1 is designed for floating with the top facing upwards, but maintaining this upward-facing position is difficult in the turbulent currents of a tsunami or flood, or in flowing rubble. Therefore, it is entirely possible for the shelter to capsize or flip over. In such a state, the hatch located at the top of the shelter cannot be opened, making it difficult to assess the external situation from within and to escape from the shelter.

[0009] The container of the box-shaped shelter in Patent Document 1 is made of a hexahedron, so it is likely to break if it is hit by rubble or other debris flowing in a tsunami or flood.

[0010] Furthermore, when a refugee is secured in the shelter using a safety harness with the premise of maintaining a stable posture, if the shelter rolls over or reverses, the refugee will be unable to take appropriate action and may instead fall into a dangerous situation.

[0011] One of the objectives of this invention is to provide a simple flood shelter that can further enhance the safety of refugees even in the turbulent currents of tsunamis, floods, or flowing rubble.

[0012] Another objective of this invention is to provide a more lightweight and further cost-effective simple shelter for flood refuge.

[0013] Methods for solving problems

[0014] The simple refuge for flood evacuation of the present invention comprises: a floating body made of synthetic resin, which is cylindrical and has a space for accommodating people defined inside; the floating body has a first entrance and exit formed on a part of the side for people to enter and exit, and a second entrance and exit and a third entrance and exit respectively provided at both ends in the length direction for people to enter and exit.

[0015] A door that prevents the intrusion of water from the outside and seals the first inlet / outlet of the buoyant body in a manner that allows it to be opened and closed; and

[0016] The cover prevents water from entering from the outside and closes the second and third inlets of the float in a way that can be opened and closed. When the float is immersed in water, it is used in a horizontal position with the length direction of the float in the middle.

[0017] According to this structure, by forming the floating body that defines the containment space of the person into a cylindrical shape, the floating body becomes difficult to damage, and by providing three entrances and exits, even if two of the three entrances and exits are submerged in water, the person can still detach from the remaining entrances and exits.

[0018] Preferably, the second and third inlets / outlets are configured such that cylindrical portions are formed protruding outwards.

[0019] A thread is formed on the outer peripheral surface of the cylindrical portion, and the cover is formed into a cap shape that can be opened and closed by engaging with the thread.

[0020] Based on this structure, the cover can be formed inexpensively.

[0021] Preferably, annular protective members made of synthetic resin are provided at both ends of the buoy body. The protective members have an outer diameter that is the same as the outer diameter of the buoy body, are arranged to surround the cover body, and have a sealed cavity inside, which is independent of the receiving space.

[0022] According to this structure, although the two ends of the buoy are prone to damage from collisions with rubble or other fluids, this can be mitigated by the inclusion of protective components. These protective components also function as floats, but because they are independent of the containment space, damage to the protective components will not affect the buoy.

[0023] When in use, the buoyant body is used in a horizontal, sideways position with its length in the same direction.

[0024] According to this structure, since the buoy is a cylindrical, longitudinally elongated structure, it is difficult to maintain its posture in the longitudinal direction when submerged in water. However, by using it in a horizontal position, even in rapids, it is possible to suppress the dangerous situation of the buoy flipping over.

[0025] Preferably, the device includes a safety harness consisting of two straps extending side-by-side and separated from each other between the two ends of the buoy in the longitudinal direction, used to prevent the refugee from tipping over by positioning the refugee's body between the inner circumferential surface of the buoy and the two straps.

[0026] According to this structure, refugees can prevent themselves from tipping over simply by entering between these two straps and the inner circumference of the buoyant body; no other operation is required. Refugees also do not need to unfasten their safety harnesses when exiting the shelter.

[0027] Invention Effects

[0028] According to the present invention, a simple flood shelter is provided that can improve the safety of refugees even in turbulent waters or flowing rubble during tsunamis, floods, or other flood disasters.

[0029] Furthermore, according to the present invention, a lightweight and low-cost simple shelter for flood refuge can be provided. Attached Figure Description

[0037] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0038] exist Figure 1 and Figure 2 The diagram shows the basic structure of a simple flood shelter (hereinafter referred to as a shelter) 1 according to one embodiment of the present invention.

[0039] like Figure 1 and Figure 2 As shown, the shelter 1 has a floating body 10 that is cylindrical and has a containment space SP for the occupants inside.

[0040] The buoy 10 is formed of a relatively lightweight, high-strength and durable synthetic resin such as vinyl chloride, and an entrance 11 for people to enter and exit the containment space SP is formed on a part of its side.

[0041] In the length direction of the buoy 10 ( Figure 2 The buoyant body 10 has an end wall 10e1 at its upper and lower ends, and a circular entrance / exit 12 for people to enter and exit is formed at the center of each end wall 10e1. A cylindrical portion 13 is formed around the entrance / exit 12 and faces outward. The cylindrical portion 13 is also formed of the same material as the buoyant body 10.

[0042] Threads 13a are formed on the outer circumferential surface of the cylindrical portion 13.

[0043] The inlet / outlet 12 is sealed in an openable / closable manner by screwing the thread 30a formed on the inner circumference of the cap 30, which is made of a synthetic resin such as polyethylene and is formed in a cap shape, into the thread 13a formed on the cylindrical portion 13. This prevents water from entering the receiving space SP from the inlet / outlet 12. Furthermore, in Figure 2 The image shows the state in which the cover 30 has been removed from the thread 13a.

[0044] Handles 31 for rotating the cover 30 are provided on both the outer and inner sides of the cover 30. Thus, the cover 30 can be rotated from both the outside and the inside of the float 10.

[0045] like Figure 1 As shown, the door 20 is large enough to cover the entrance 11 and is formed to be curved with a curvature consistent with the circumference of the levitation body 10. Figure 1 As shown, a handle 21 for opening and closing the door 20 is provided on the outer side of the door 20. The door 20 is also made of the same material as the floating body 10. The door 20 is connected to the floating body 10 via a hinge HG and can be opened outward relative to the entrance / exit 11.

[0046] Here, Figure 4This indicates the state after the door 20 is opened. Around the entrance 11 formed on the floating body 10, two sealing components SL1 and SL2 made of rubber-like material are provided at a given interval.

[0047] On the other hand, a sealing component SL3, made of rubber-like material, is provided on the inner side of the door 20, embedded between the two sealing components SL1 and SL2. In addition, multiple (3) locking mechanisms 50 are provided on the inner side of the door 20.

[0048] The locking mechanism 50 is designed to lock the door 20 so that the door 20, which closes the entrance 11, cannot be opened.

[0049] like Figure 5 As shown, the locking mechanism 50 includes: an operating rod 51 rotatably supported on a support member 54 about a shaft 53 provided on the door 20; and a locking member 52 provided at the front end of the operating rod 51.

[0050] The locking mechanism 50 is engaged by manually operating the lever 51. Figure 4 The locking component 52 of the operating lever 51, shown in the solid line, is positioned so as not to engage with the engaging portion 10t around the entrance 11 of the buoy 10, thereby allowing the door 20 to open and close freely.

[0051] like Figure 6 As shown, when the door 20 is closed, the sealing member SL3 is embedded between the two sealing members SL1 and SL2, sealing the space between the floating body 10 and the door 20. Furthermore, by manually operating the operating lever 51, the locking member 52 of the operating lever 51 engages with the engaging portion 10t around the entrance / exit 11, thereby locking the door 20 in a manner that prevents it from opening when the entrance / exit 11 is closed. Additionally, Figure 6 This is a diagram showing the locking mechanism 50 as viewed from the SP side of the containment space.

[0052] like Figure 1 as well as Figure 2 As shown, annular protective members 40 are provided on the end walls 10e1 at both the upper and lower ends of the buoy 10. The protective member 40 has a rectangular cross-section and is sealed inside a cavity 41. The cavity 41 is separate from and independent of the receiving space SP of the buoy 10. The protective member 40 is also formed of the same material as the buoy 10.

[0053] The outer diameter of the protective component 40 is the same as the outer diameter of the buoy 10, and it surrounds the cover 30 on its inner circumference. The height of the protective component 40 is higher than the height of the cover 30.

[0054] The two ends of the float 10 are prone to collision with rubble and other debris carried by the rapids of a flood. Therefore, a protective member 40 is provided to suppress damage to the float 10, including the cover 30, caused by such collisions. Even if the protective member 40 is damaged and water or other substances seep into the internal cavity 41, it will not affect the float 10.

[0055] In addition, the protective component 40 also functions as a float to generate buoyancy.

[0056] When storing Shelter 1, from the perspective of saving installation space, such as Figure 1 As shown, it is preferable to use a vertical arrangement with the length direction as the top and bottom.

[0057] When using, such as Figure 3 As shown, it is used in a horizontal position with the length direction of the buoy 10 being transverse.

[0058] When a person EH enters Shelter 1, first, Shelter 1 is tilted horizontally to open door 20 and enter the containment space SP. By tilting Shelter 1 horizontally, the position of door 20 is lower than in the vertical position, making it easy for even children or the elderly to enter the containment space SP of Shelter 1.

[0059] like Figure 3 As shown, a safety harness 60 is provided inside the float 10, consisting of two flexible straps extending side-by-side and separated from each other between the two ends of the float 10 along its length. By positioning the body of the person EH between the inner circumferential surface 10c of the float 10 and the two straps 61 and 62, the person EH is prevented from tipping over. When the person EH enters between the two straps 61 and 62 and the inner circumferential surface 10c of the float 10, tipping over is prevented simply by gripping the straps 61 and 62; no other operation is required. The person EH does not need to release the safety harness 60 when exiting the shelter 1.

[0060] like Figure 3 As shown, a window 70 made of transparent resin material is embedded in the side of the floating body 10. By setting the window 70, the person EH who is sheltering in the shelter 1 can understand the external situation.

[0061] When using the shelter 1, the side entrance 11 and the two end entrances 12 of the floating body 10 are sealed by doors 20 and covers 30, respectively. Therefore, it is necessary to introduce air into the interior of the floating body 10 as needed, and air vents AH are formed in the doors 20 and covers 30, respectively. Alternatively, air vents AH can be provided in other locations.

[0062] Figure 7The diagram shows an air hole AH and a plug 80 for sealing the air hole AH. The air hole AH is formed as a tapered hole tapering at the tip, such as... Figure 7 As shown in (a), water intrusion can be reliably prevented by inserting a tapered plug 80, which is tapered at the front end, into the air hole AH. In the event that air needs to be introduced into the containment space SP of the shelter 1, the plug 80 of the air hole AH that is not submerged in water is manually pulled out, thereby preventing water intrusion. Figure 7 As shown in (b), air can be drawn in through the air hole AH. In addition, the plug 80 is connected to the door 20 or the cover 30 via the chain 81 in a way that prevents it from being lost.

[0063] According to this embodiment, by making the floating body 10 of the containment space SP that defines the containment person cylindrical, the floating body 10 becomes difficult to damage. Furthermore, by providing three entrances 11, 12, 12, even if two of the three entrances are submerged in water, the person can still detach from the remaining entrance.

[0064] Furthermore, according to this embodiment, by providing protective components 40 at both ends of the buoy 10, damage to the buoy 10 from collisions with rubble or the like can be suppressed.

[0065] Furthermore, according to this embodiment, since the buoy 10 is a cylindrical longitudinal shape, it is difficult to maintain its posture in the longitudinal direction when immersed in water. However, by using it in a horizontal position, even in rapids, it is possible to prevent the buoy 10 from becoming in a dangerous state such as flipping over.

[0066] 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 described in the patent claims.
