Description

[[Technical Field]]

[0001] The present invention relates to a vehicle waterproof cover that provides evacuation facilities against tsunamis and storm surges. [[Background Art]]

[0002] In recent years, massive earthquakes have occurred frequently in various parts of the world. Also, due to global warming , storm surges accompanying the occurrence of powerful typhoons and hurricanes also cause great damage. Storm surges are a phenomenon in which the sea level becomes abnormally higher than usual due to strong winds caused by typhoons or low-pressure systems and changes in atmospheric pressure, and are also known by alternative names such as "wind tsunami" or "storm surge tsunami". In contrast, a "tsuna mi" is alternatively called an "earthquake tsunami".

[0003] Among massive earthquakes, trench-type earthquakes that occur particularly on the seabed trigger huge tsunamis. In Ja pan, the Pacific coastal area lies along a belt-shaped region where trench-type earthquakes may occur, and the fact is that the Pacific coastal area of Japan is constantly exposed to the threat of huge tsunamis.

[0004] Tsunamis and storm surges destroy above-ground structures via their surging forward and sweep above-ground objects (including people and vehicles) into the wave, then drag them out to sea via backwash. Furthermore, as the height of a large wave coming from the sea increa ses, its forward momentum increases, but even when the wave height reaches approximately the position of a person's knees, it still has enough energy to engulf a person. Although tsunamis are described as waves, they are actually masses of seawater, so they do not break apart and their energy is greater than one can imagine.

[0005] The arrival speed of a tsunami generated near the coast is within tens of minutes from the occurrence of the earthquake (for example, about 5 minutes ​It is said that the first wave will arrive within approximately 30 minutes. Moreover, the tsunami will be several times that height. It is also said that they can migrate inland to areas of high sea level.

[0006] Therefore, in the event of an earthquake, not only people in coastal areas but also those adjacent to the coast People in areas with relatively low elevations anticipated the arrival of a tsunami and took action within a short time. It is necessary to evacuate to the highest possible ground. However, the elderly and patients hospitalized in hospitals, etc. Adults, young children in daycare centers or elementary schools, etc., should be able to move away from the coast on their own in a short amount of time. It is difficult to evacuate to higher ground, and the more people there are, the more difficult evacuation becomes. Problems arise such as the time required to do so becoming longer. Also, if there is no high ground nearby, Not only vulnerable people such as the elderly, children, and the sick, but even adults can be killed in a short time by the tsunami. It will become difficult to escape.

[0007] In order to secure a safe place in a short time, provide safe facilities during that short time. To prevent being swallowed by waves and also to prevent being pulled into the sea by the receding waves of a tsunami. Technologies have been proposed. Furthermore, in recent years, inland flooding has become frequent due to torrential rains, and solutions to this problem are desired.

[0008] Patent Document 1 describes a tsunami capsule that is spherical and equipped with chairs and beds inside. This is disclosed. Furthermore, Patent Document 2 describes how a spherical shape is supported by a gimbal structure to improve stability during rotation. It has been disclosed that this will be ensured.

[0009] Patent Document 3 describes a tsunami shelter that is vertically movable and sandwiched between steel guides in the event of a tsunami. Sometimes, techniques have been revealed to rescue people inside by moving onto the guide. Patent Document 4 discloses an invention that uses a ship capable of accommodating a large number of people, which is tied to a stake fixed to the ground, as a tsuna mi shelter.

[0010] In Patent Document 5, an administrative body discloses a warning information provision system that predicts damage caused by large typhoons and localized torrential rain in specific areas. Although such a system makes it possible to know the risk of inland water flooding in advance, there is a problem that concrete measures for preventing damage caused by flooding of vehicles are left to individual responsibility.

[0011] For evacuating including sick people and elderly people from tsunamis and storm surges, travel from places where people normally live to evacuation facilities poses a major problem. To reduce travel time, it is sufficient to prepare evacuation facilities in the immediate vicinity of places where people normally live, but there are many cases where it is difficult to secure installation sites for evacuation facilities. There is also the problem that preparing evacuation facilities imposes a considerable cost burden. [PRIOR ART DOCUMENTS] [PATENT DOCUMENTS]

[0036] Figure 1(A) shows a perspective view of a sheet constituting a rectangular vehicle waterproof cover according to the present invention. For the sake of explanation, the four corners of the sheet are designated as A, B, C, and D. The length of the long side of the sheet SL (between A and B, between C and D) is greater than the length of the vehicle CW, and the length of the short side SW (between B and C, between D and A) is greater than the width of the vehicle CW. Furthermore, it is preferable for the aesthetic finish and improved waterproof performance if the difference between the length of the long side of the sheet SL and the length of the vehicle CW is not less than the difference between the length of the short side SW and the width of the vehicle CW (SL-CL) ≥ (SW-CW).

[0037] The seat has strip-shaped positioning marks 11 used for positioning the vehicle. Additionally, slack 12 can be added between the positioning marks 11 of the vehicle's waterproof cover to accommodate the downward protrusion of the tires.

[0038] The sheet consists of a bottom section corresponding to the bottom of the vehicle, a front section corresponding to the front of the vehicle, a rear section corresponding to the rear of the vehicle, and a side section corresponding to the sides of the vehicle. Each of these sections is connected to the others in a watertight manner, and it is preferable to manufacture it by cutting it from a single sheet in order to reduce the number of connections. The connections are made watertight by fusion, adhesive, etc., to prevent water leakage. On the side sections of the vehicle, as shown in Figure 9(A), it is preferable to have a bellows-like slack so that the doors can be opened and closed and passengers can get in and out after the vehicle waterproof cover is installed on the vehicle, and to secure it with a flat fastener when not in use. This slack may be provided between the positioning marks in Figure 1(B).

[0039] For vehicle waterproof covers, aramid fibers are used as the sheet material if toughness is required, and polyvinyl chloride is impregnated or coated for waterproofing. Materials such as Hypalon®, polyester, nylon®, Gore-Tex®, and Ecostron®, which are used in rubber boats, can also be used. It is also preferable to thicken the part of the vehicle waterproof cover that receives pressure between the ground and the wheels, or to reinforce it with other materials.

[0040] The sheet 9 of the vehicle waterproof cover has numerous grommets that serve as belt loops for securing belts. The grommet positions are numbered from grommet (1) between the short sides A and D in Figure 1(B), and proceed counterclockwise in a complete circle to grommet (20) between the short sides A and D.

[0041] The belt may have elastic material woven into a portion of the upper edge of the vehicle waterproof cover. For example, rubber may be woven into the upper edges of the front and rear sections, and the belt may be passed through the left and right sides, with the length adjusted by pulling the belt through from inside the vehicle. The ends of the belt may also be fastened together with the material of the vehicle waterproof cover using eyelets or similar fasteners, or secured to the belt loops using carabiners.

[0042] In Figure 1(B), dotted lines 21 and 22 indicate where the seats are joined by belts, forming the first folded triangle at the rear of the vehicle. Dotted lines 25 and 26 also indicate where the seats are joined by belts, forming the first folded triangle at the front of the vehicle.

[0043] In Figure 1(B), the dashed lines 23 and 24 indicate where the seats are joined by belts, forming a second fold rectangle at the rear of the vehicle, while the dashed lines 27 and 28 indicate where the seats are joined by belts, forming a second fold rectangle at the front of the vehicle.

[0044] Figure 2(A) shows the vehicle in its designated position on the seat. The strip-shaped positioning mark 11 is effective for getting the vehicle onto the seat.

[0045] Figure 2(B) shows how opposing ends of seats on the side of the vehicle are connected by a belt 20 that extends over the top of the vehicle, raising the side section to a height H. Near the top of the seat on the left side, grommets (5), (6), and (7) are provided to serve as belt holes. Oppositely, grommets (16), (15), and (14) are provided on the right side. By passing the belt through these belt holes and tightening it, the lower part of the vehicle is covered in a drawstring shape by the vehicle waterproof cover to a height H. In addition to lashing bells used for securing cargo, using elastic rubber or a combination of rubber and non-elastic nylon for the belt allows for easy narrowing of the gap between the vehicle waterproof cover and the vehicle, thereby increasing the degree of contact between the vehicle waterproof cover and the vehicle. DC buckles are preferable for connecting the belts. The length of the belt is adjusted in advance to an appropriate length determined by the dimensions of the vehicle and the seat, and the seats can be easily connected with the belt by joining the male and female buckles during installation.

[0046] Figure 3(A) shows the vehicle positioned based on the positioning marks 11 on the seat, ready to cover the rear of the vehicle. Figure 3(B) shows how the eyelets (9) at the corners D of the seat are connected to the eyelets (13) on the right side of the vehicle to form a triangle.

[0047] Figure 4(A) shows the formation of the second folds on the left and right sides at the rear of the vehicle. Figure 4(B) shows how the second folds are formed by tying eyelet (10) to eyelet (7) with belt 24. It also shows how a rectangle is formed by tying eyelet (11) to eyelet (14) with belt 23 at the second fold.

[0048] Figure 5(A) shows the front of the vehicle after it has entered the vehicle waterproof cover and is positioned in the designated location. Eyelet (19) is connected to eyelet (3) with belt 26, and eyelet (2) is connected to eyelet (18) with belt 26 to form the first fold. Figure 5(B) shows the triangular shape formed by connecting eyelet (19) to eyelet (3) with belt 25.

[0049] Figure 6 shows how the first folds on the left and right sides are formed at the front of vehicle 100, creating a triangle.

[0050] Figure 7(A) shows how the second fold is formed at the front of the vehicle 100 by connecting the grommet (20) between the midpoint AD of the short side AD and corner D with the grommet (17) on the long side CD using the belt 27. Figure 7(B) shows the second fold completed at the front of the vehicle, completing the installation of the waterproof vehicle cover that covers the vehicle 100.

[0051] Figure 8(A) shows the vehicle after the waterproof cover has been installed. The product's trademark 60 can be placed on the front and rear of the vehicle to enhance its value. Figure 8(B) shows the vehicle with the top cover 31 placed over it, and the seat secured tightly to the vehicle with a body belt (circumferential belt) around the perimeter. The top cover improves waterproofing performance by preventing water from entering between the vehicle and the seat due to rain or splashes. In addition, tightening the seat with the body belt (circumferential belt) 30 improves the degree of contact between the seat and the vehicle.

[0052] Figure 9(A) shows a vehicle equipped with a cushioning member 50 around the vehicle's waterproof cover to prevent collisions with floating objects and structures. Figure 9(B) shows the vehicle being secured to an external pillar with a securing rope 40. This securing rope 40 helps prevent the vehicle from floating away.

[0053] Figure 10(A) shows how the vehicle width is designed to accommodate the protruding tires. The clearance may also be provided between the wheels. Figure 10(B) shows a vehicle placed in water with its lower part covered in a drawstring-like vehicle waterproof cover. In water, the entire vehicle body is subjected to buoyancy, so the wheels, which previously supported the weight of the vehicle, no longer support the weight and move downward. The size of this downward movement is usually 10-20 cm. The bottom surface of the vehicle waterproof cover is sufficiently larger than the bottom area of ​​the vehicle's chassis, so the water pressure causes each surface of the vehicle waterproof cover, except for the areas where components that conform to the shape of the vehicle and create gaps are placed, to press against the vehicle, resulting in a nearly tight seal and a waterproof state. If the bottom area of ​​the vehicle is 8 square meters, 20-30 cm submerged in water will generate a buoyancy of 1.6 to 2.4 tons. The water surface is usually around the position of the vehicle's bumper. The wheels that protrude below the vehicle body act as stabilizers in the water.

[0054] The procedure for installing the sheet of the vehicle waterproof cover is as follows: Place the vehicle in the designated position on the vehicle waterproof cover; with respect to the sides of the vehicle, tie the sheet upright by connecting opposite sides with belts to cover the sides of the vehicle to a height H; at the front and rear of the vehicle, tie the two corners of the short side of the sheet to designated positions on the long side of the sheet to create a first fold; tie the midpoint between the two corners and a designated point between the two corners to designated positions on the long side of the vehicle waterproof cover to create a second fold; and complete the installation by forming the sheet into a bag shape that encloses the vehicle, such that the upward-facing openings created by the first and second folds do not fall below the height H.

[0055] While embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and any modifications that do not depart from the spirit of the present invention, even if added, are included within the scope of the present invention.
