Description

[Technical field]

[0001] The present invention relates to a body shelter that can be used as an indoor picture frame or ornament material in everyday life, and can become a shelter to protect the bodies of family members living together within a few seconds during a major earthquake (equivalent to a seismic intensity of 7). [Background technology]

[0002] On the evening of New Year's Day this year (2024), a major earthquake occurred on the Noto Peninsula, causing many houses to collapse. In particular, the prefectural government published the death toll in Ishikawa Prefecture up until January 20th of this year. Of the more than 240 people who died, 103 of whom had their families' consent, revealing the tragic reality that an astonishing 90% of them were crushed to death by collapsing houses.

[0003] In the 2016 Kumamoto earthquake and the Great Hanshin-Awaji earthquake, many houses collapsed, and many reports were published of people being crushed to death by the collapse of their houses. In the 2011 Great East Japan Earthquake, the damage was diversified, with tsunamis and fires. The strength of the houses is the most important factor in the deaths caused by the collapse of houses.

[0004] Houses built in the 2000s that comply with the Building Standards Act have the advantage of being less likely to collapse, but the reality is that two-story wooden houses built before that time are at considerable risk of collapsing in an earthquake of magnitude 7. Japan, a country prone to earthquakes, has a considerable number of these seemingly fragile houses.

[0005] The Anshin Home Shelter in cited document 1 (Utility Model Registration No. 3119420) is an invention in which an upwardly bulging circular arch is formed, and below this forms a space into which the body can enter, and if one sleeps within this space, even if the house collapses during a major earthquake, one's life can be saved, and it is recognized as a shelter that provides a certain degree of safety. However, in everyday life, having this in one's bedroom takes up space and can be a hindrance to sleep. It would be difficult to popularize it.

[0006] The personal shelter in cited document 2 (Patent No. 6482495) is also an invention in which a person can sleep in the interior space of a polygonal shelter made by combining many rods, forming a trapezoid when viewed from the front and a triangle when viewed from the side, during everyday life, and can survive even if the house collapses during a major earthquake. However, this invention is thought to be difficult to popularize, especially since there would be great resistance to having this on a bed in the bedroom in everyday life, and it would also interfere with sleep.

[0007] The earthquake-resistant shelter in cited document 3 (Patent No. 5469137) is an invention that protects houses from collapse, and if an individual gets up immediately during a major earthquake, even if they are sleeping, and enters the earthquake-resistant shelter, their life can be saved even if their house collapses. This invention only requires space to place it in a bedroom, etc.

[0008] It is true that the shelters described in References 1, 2 and 3 not only take up space in a bedroom or living room during everyday use, but also often get in the way of daily living activities, making it difficult for them to become widespread. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Utility model registration No. 3119420 [Patent Document 2] Patent No. 6482495 [Patent Document 3] Patent No. 5469137 Summary of the Invention [Problem to be solved by the invention]

[0010] Therefore, what is needed is something that does not function as a shelter during everyday (normal) times, but does not get in the way, and only serves as a shelter in the event of a major earthquake, but there have been no products that meet this need.However, this dual purpose of being able to function both during everyday times and during a major earthquake has been desired and demanded even in earthquake-prone Japan.For this reason, the problem (technical problem or objective, etc.) that this invention aims to solve is to function as a shelter that protects the body only during a major earthquake, without getting in the way during everyday times. [Means for solving the problem]

[0011] As a result of intensive research by the inventor to solve the above-mentioned problems, the inventor has solved the above-mentioned problems by providing the invention of claim 1 as a body shelter characterized in that the rectangular main plate is a horizontal metal thin plate with the long side in the longitudinal direction and the short side in the width direction, and at both ends in the longitudinal direction of each plate, the rectangular main plate is made of the same material as the rectangular main plate and is provided with end raised portions that are maintained at the same angle and inclined downward toward the outside with the horizontal line of the metal thin plate as a reference, and a tension string-like object is tied between the opposing end raised portions, and in normal times, the rectangular main plate is flat, and in the event of a major earthquake, the tension string-like object is appropriately shortened by manual pulling force, and the rectangular main plate is formed and fixed in a curved shape along the entire longitudinal direction, and the end raised portions are formed vertically,

[0012] The above problem was solved by the invention of claim 2, which is a body shelter characterized in that the long side of the rectangular main plate is a horizontal metal thin plate with the length direction and the short side is a width direction, and at both ends of each longitudinal direction, end raised portions are provided that are made of the same material as the rectangular main plate and are maintained at the same angle with a downward incline toward the outside based on the horizontal line of the metal thin plate, and a tension string-like object is tied between both opposing end raised portions, and in normal times, the rectangular main plate is flat, and in the event of a major earthquake, the tension string-like object is appropriately shortened by a tensile force generated by power, and the rectangular main plate is formed and fixed in a curved shape along the entire longitudinal direction, and the end raised portions are formed vertically.

[0013] The above problem is solved by the invention of claim 3, which is a body shelter as described in claim 1 or 2, characterized in that the end raised portion has a predetermined angle within the range of approximately 110 degrees to approximately 150 degrees from the inside of the underside to the outside, with the horizontal line as a reference.

[0014] The invention of claim 4 is or 2 The problem is solved by providing a body shelter as described in claim 1, characterized in that a reinforcing body is formed across both end portions in the longitudinal direction of the rectangular main plate and the end raised portion. 5 The above problem has been solved by providing a body shelter according to the invention as described in claim 2, characterized in that a small hoist as the power source is provided at an appropriate position on the tension cord-like material. Effect of the Invention

[0015] In the invention of claim 1 or 2, the flat rectangular main plate is not used as a shelter during everyday (normal) times, but is placed against a wall or laid horizontally in a pictorial manner so as not to get in the way of the room, and only in the event of a major earthquake is the entire longitudinal direction of the rectangular main plate curved (three-dimensionally formed) and fixed by human or mechanical power, which immediately serves as a shelter for the body. This has the greatest advantage that even if a major earthquake occurs and the house collapses, the shelter of the present invention can save lives. Even if it is assumed that it will be bent by human or mechanical power, various metal plates can be assumed, and furthermore, stainless steel metal plates have the advantage of being thinner in terms of elasticity than thin galvanized steel plates, making them easier to handle.

[0016] The invention of claim 3 provides a more effective curved shelter. The invention of claim 4 has the advantage that the strength of thin plate materials can be guaranteed by adding a reinforcing body. The invention of claim 5 has the advantage that the operability can be improved by using a small hoist as the power source.

[0017] In the present patent specification, "flat" means flat, and when placed on the ground as a whole, it forms a flat or horizontal surface. When placed on a vertical wall inside or outside a building, it is formed as an upright surface. In particular, when it is bent by several degrees, specifically, as shown in FIG. 15(B), it is formed at an angle θ1 from both sides. Specifically, even if the bend is about 1 degree to about 3 degrees, the angle θ1 is included in the concept of "flat" [FIG. 15(B)(ii) and (iii)]. Preferably, the angle θ1 is configured to be about 2 degrees to about 3 degrees.

[0018] In the present patent specification, the term "curved" refers to a state in which the entire longitudinal direction (X direction) of the rectangular main plate is curved and fixed. This refers to the entire longitudinal direction of the rectangular main plate 1 being curved and bulged in the Z direction (direction perpendicular to the horizontal plane having the X direction) during a major earthquake, and the "curved" state also includes bending into a bow shape or a semicircular arch shape. Specifically, as shown in FIG. 15(C), the angle θ2 is formed with respect to the horizontal line. The angle θ2 is curved at about 20 degrees to about 60 degrees [FIG. 15(C)(iv) and (v)].

[0019] Preferably, the angle θ2 is set to about 30 degrees to about 50 degrees. In the best case, the angle θ2 is about 35 degrees to about 45 degrees, and further, the angle θ2 is considered to be about 40 degrees or more, close to 45 degrees. It should be noted that the angle θ2 is based on the horizontal line only for the rectangular main plate. In particular, when the end raised portion is formed vertically, the angle θ3=90 degrees+angle θ2. This point will be described later. In particular, a major earthquake does not necessarily have to be an intensity 7 earthquake, but can be an intensity 6-low or 6-high earthquake depending on the location.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [First embodiment of the manual type made of thin metal plates] A first embodiment of the manual type using a thin metal plate will be described with reference to Figures 1 to 3, 5 and 6. First, the basic main member is a rectangular main plate 1 made of a thin metal plate, which is elongated in each of the figures as shown in Figures 1(A), 2(A) and 7(A), with a long side 11 (long side) extending in the longitudinal direction (X direction) and a short side 12 (shorter side) extending in the width direction (Y direction).

[0022] The basic shape of the rectangular main plate 1 is composed of long sides 11, 11 and short sides 12, 12 around the periphery, and in particular, the width (short side 12: Y direction) is 1 and the length in the longitudinal direction (long side 11: X direction) is about twice as long. Specifically, the short side 12 of the width (Y direction) is about 90 cm, and the long side 11 of the longitudinal width (X direction) is about 180 cm. In the basic shape, the rectangular main plate 1 is flattened in daily use [see FIG. 20(B)]. In some cases, it may be slightly curved, and the length in the longitudinal direction may be shortened by about 1 or 2 cm compared to when it is flattened, but in this application, the numerical values ​​are the same as when it is flattened.

[0023] Reference numeral 2 denotes end elevation parts, which are made of the same material as the rectangular main plate 1 and are integrally formed on both longitudinal ends of the rectangular main plate 1 in an inclined manner with a predetermined angle θ3 in the range of about 110 degrees to about 150 degrees from the inside to the outside with respect to the horizontal line as the horizontal shape. The state of such angle θ3 is such that the angle θ3 is maintained at approximately the same angle even in a normal state or in a large earthquake when the longitudinal direction of the rectangular main plate 1 is appropriately shortened by a pulling force by human or power and formed into a curved shape and fixed, and the end elevation parts 2 are formed vertically (including vertically within about 85 degrees). This completes the present invention. The change in this angle is also related to the quality and thickness of the metal material. Of course, when a reinforcing body 3 described later is provided, the angle θ3 is maintained at the same angle.

[0024] The angle θ3=90 degrees+angle θ2, and the angle θ3 is preferably about 120 degrees to about 140 degrees (θ2 is about 30 degrees to 50 degrees). More preferably, it is about 125 degrees to about 135 degrees (35 degrees to 45 degrees), and in the best case, it is about 130 degrees (a little over 40 degrees, close to 45 degrees). The bending process at the angle θ3 is performed by a large press. In the present invention, the rectangular main plate 1 is flattened in normal use, and the tension string-like object 4 described later is configured to be in a tension-free state. Even if there is a tension of about 1 kg or less, this specification includes the concept of tension-free. Furthermore, there are specifically three types of the rectangular main plate 1 and the raised portions 2, 2 at both ends.

[0025] The three types are S type, M type, and L type. As shown in Fig. 10(C), (D), and (E), in this example, θ3 is described as 135 degrees. The width (X direction) of the S type is 90 cm, the longitudinal direction of the rectangular main plate 1 is 170 cm, and the raised height (Y direction) of the raised parts 2, 2 at both ends is about 25 cm. In this case, the total length in the longitudinal direction is about 205 cm. The width (X direction) of the M type is 95 cm, the longitudinal direction of the rectangular main plate 1 is 175 cm, and the raised height (Y direction) of the raised parts 2, 2 at both ends is about 30 cm. In this case, the total length in the longitudinal direction is about 220 cm. The width (X direction) of the L type is 100 cm, the longitudinal direction of the rectangular main plate 1 is 180 cm, and the raised height (Y direction) of the raised parts 2, 2 at both ends is about 30 cm. In this case, the total length in the longitudinal direction is set to about 225 cm.

[0026] The metallic thin plates of the rectangular main plate 1 and both end raised portions 2, 2 are formed of galvanized steel plate, stainless steel plate made of iron and chromium mixed therein, etc., and it is preferable to appropriately select a material having excellent elasticity. A reinforcing body 3 is formed to straddle both end portions in the longitudinal direction of the rectangular main plate 1 and both end raised portions 2, 2. There are several embodiments of the reinforcing body 3.

[0027] [Reinforcement measures for the rectangular main plate 1 and the raised end portion 2 made of thin metal plate] The first is formed as a reinforcing rib 31 as shown in Fig. 1 and Fig. 2. The reinforcing rib 31 is formed at two places at the bending portion, but may be formed at three or four places. The reinforcing rib 3 can be formed only by pressing, so large equipment is required, but no additional parts are required, and mass production is possible, and overall it may be manufactured relatively inexpensively. The second is a separate member, and as shown in Fig. 5 (A) and (B), a reinforcing angle 32 at an angle θ3 when viewed from the side is fixed with a fixing device such as a screw. Also, as shown in Fig. 5 (C) and (D), the third is also a separate member, and may be configured as a reinforcing plate material 33 whose cross section of the metal plate has an angle θ3 and has the same width as the short side 12 of the rectangular main plate 1 or the lower end side 21 of the end raised portion 2, and this is also fixed with a fixing device such as a screw.

[0028] A tension string-like object 4 is tied between the opposing end raised portions 2, 2 at a midpoint (approximately the center position) in the width direction near the ends of the end raised portions 2, 2. The tension string-like object 4 is made of a metal wire or a cloth rope, etc., and is provided to withstand a tensile load of about 70.80 to about 100 kg. In everyday life, it is provided with a certain amount of slack [see Figures 1(A) and 2(A)].

[0029] In the event of a major earthquake, the tension cord-like object 4 is appropriately shortened by human pulling force (approximately 35 kg to 70 kg) while the longitudinal direction of the rectangular main plate 1 is curved and fixed, and the family (couple and children) can be hidden inside to create a body shelter. The above-mentioned human pulling force (approximately 35 kg to 70 kg) is included in the human pulling force even if it is increased by about 10 to 20%. In addition, as the concept of the present invention in the event of a major earthquake, specifically, the tension cord-like object 4 is configured as a single object with its entire length being shortened by human pulling force.

[0030] For ordinary people, a major earthquake is a disaster that may or may not occur once in a lifetime. In such a case, it is usually impossible to operate calmly. Taking this into consideration, a structure for shortening the tension cord-like object 4 appropriately has been devised. In the first type of shortening structure, as shown in Figures 1(A) and 2(A), the tension cord-like object 4 is a single continuous object, and in this case, a hook portion 5 is fixed at an appropriate position near the upper end of the tension cord-like object 4. There is a distance Q between the appropriate position of the hook portion 5 near the upper end and the locking portion 4a provided at the end of the tension cord-like object 4. The locking portion 4a is formed by rolling a part of the tension cord-like object 4 into a loop shape [see Figure 1(A)].

[0031] Specifically, the distance Q is about 25 cm when the overall longitudinal width of the rectangular main panel 1 is about 170 cm. The hook portion 5 is provided with a known stopper as necessary, but this is omitted in the drawings. In both Fig. 1 and Fig. 2, in normal times, the hook portion 5 is engaged with the engaged portion 4a near the end of the tension string-like object 4, and is contracted and fixed as shown in Fig. 1(B) from the state shown in Fig. 1(A). Even in a time of extreme tension such as a major earthquake, the hook portion 5 is located at the end of the tension string-like object 4 (at a position that is always visible, at the distance Q), so there is no need to search for the hook portion 5, which is safe.

[0032] [Actual use of the present invention: manual operation example] The shortening structure, that is, the hook portion 5 is actually engaged to shorten the distance Q of about 25 cm, and as described above, this is performed by a pulling force (about 35 kg to about 70 kg) applied by human power. This operation will be described with reference to FIG. 7. First, in normal times, as shown in FIG. 7(A), a person is sleeping on a bed or a futon (bedding is omitted) and the product of the present invention is placed upright. Next, in the unlikely event of a major earthquake, the person throws the futon aside, stands up, and immediately puts his / her hand on the pull handle 81, as shown in FIG. 7(B).

[0033] Immediately after, the person applies his / her body weight to the pull handle 81 and pushes it down as shown in Fig. 7(C) and (D). The person further applies his / her body weight to push it down, at which point the hook portion 5 is engaged and fixed to the upper engaged portion 4a (see Fig. 7(E)). This operation (Fig. 7(B)-(E)) is actually performed in about 2-3 seconds. After that, the entire longitudinal direction of the rectangular main plate 1 with the raised portions 2, 2 at both ends is curved and fixed in place, so that the operator and several family members can lie face down on the product of the present invention to protect themselves from the collapse of the house, as shown in Fig. 7(F).

[0034] In other words, in the event of a major earthquake, the tension cord-like object 4 is appropriately shortened by human pulling force, while the longitudinal direction of the rectangular main plate 1 is curved and fixed, and the rectangular main plate 1 with the end-mounted portions 2, 2 becomes curved, and the presence of the end-mounted portions 2, 2 allows ample space inside for several family members to hide, creating a body shelter. This is an invention that, even though it is in a nearly flat frame-like shape and does not get in the way in everyday life, can serve as a body shelter in an emergency, and a simple and reliable operating means is required to curve it in an emergency, and this invention can certainly meet this requirement.

[0035] [First embodiment of the manual type made of thin metal plates] As mentioned above, the first type of shortening structure is a simple structure in which the tension cord-like object 4 is a single continuous object composed only of a hook portion 5 provided at an appropriate position near the upper end as shown in Figures 1(A) and 2(A), but this is also a technical content that allows this to be safely and securely locked. The hook portion 5 alone is also called the shortening operation member S described below. As mentioned above, the locked portion 4a is formed by rolling a part of the tension cord-like object 4 into a ring shape, but as shown in Figure 1(E), a hanging ring 4b may also be provided. If the hook portion 5 is locked to this, it has the advantage of being easy to understand and operate in an emergency.

[0036] [Second embodiment of the manual type made of thin metal plates] Next, in the second embodiment of the manual type of the metal thin plate of the present invention, the shortening operation member S is a type of magnetic member 6, and as shown in FIG. 3, it is composed of a magnetic part 61 made of a magnet material and an iron-based member 62 that magnetizes it. In this case, the tension string-like object 4 is also a continuous object, and the magnetic part 61 is fixed at a certain position from the upper end of the tension string-like object 4. The iron-based member 62 is provided near this upper end. In this case, there is also a distance Q between the magnetic part 61 and the iron-based member 62. Lock washers 4c, 4c are often used to fix the magnetic part 61 or the iron-based member 62 in the middle of the tension string-like object 4. There are other known examples that require reliable fixation.

[0037] In this case as well, the magnetic part 61 is positioned as shown in Fig. 3(C) so that they can easily be magnetically coupled. In the event of an emergency (major earthquake), a reliable magnetic coupling between the upper iron-based member 62 and the lower magnetic part 61 is required. In the embodiment, the lower side is the magnetic part 61 and the upper side is the iron-based member 62, but although not shown, the reverse is of course also possible.

[0038] [Third embodiment of the manual type made of thin metal plates] In addition, in the third embodiment of the manual type of metal thin plate of the present invention, when the shortening operation member S is an adsorption member 7, as shown in Fig. 4, it is composed of a rubber-based adsorption part 71 with a concave lower surface and a flat rubber-based plate part 72. In this case, the tension string-like object 4 is also a single continuous object, and the adsorption part 71 is fixed at a certain position from the upper end of the tension string-like object 4. The plate part 72 is provided near this upper end. In this case, there is also a distance Q between the adsorption part 71 and the plate part 72.

[0039] In this case, too, the position of the suction portion 71 is configured as shown in Fig. 4(C) so that the two can be easily attached by suction. In the event of an emergency (major earthquake), a reliable suction attachment between the suction portion 71 on the upper side and the plate portion 72 on the lower side is required. In the embodiment, the lower side is the plate portion 72 and the upper side is the suction portion 71, but although not shown, the reverse is of course also possible.

[0040] [Examples of use of the present invention] It is installed by leaning it against a wall in a room. It is used to stabilize the leaning state and as a drinking measure in an emergency. Specifically, as shown in FIG. 10(A), it is preferable to fix a holder 88 for a PET bottle 45 containing drinking water to an appropriate place on the back surface of the end elevation part 2 and tie it to the neck of the PET bottle 45. Specifically, the holder 88 is composed of a front piece 88a, a rear piece 88b, and a mountain-shaped part 88c, one side of which is glued to an appropriate place on the back surface of the end elevation part 2, and a tongue piece 88d that supports the PET bottle 45 is cut out and formed. The PET bottle 45 is also provided with a whistle 46, which is useful for early rescue in the event of a major earthquake, when the house collapses and the person lies horizontally and is saved within the rectangular main board 1 and the end elevation parts 2, 2 (semicircular arch invention).

[0041] [Metal sheet metal electric type] Next, an embodiment of the present invention for electrically bending a metal thin plate will be described. In particular, the tension string-like object 4 provided on the rectangular main plate 1 of the metal thin plate is electrically bent. Specifically, as shown in Figs. 12(A) and (B), a small hoist 9 is provided near the tip of the tension string-like object 4, and a locking portion 97 of the small hoist 9 is locked at the middle position of the end raising portions 2, 2. A rotating drum portion 92 is built into the outer casing 91 of the small hoist 9, and a wire 94 is wound around it, and a hook piece 93 exposed on the outside of the outer casing 91 can be wound up via a motor portion 95 and a power supply portion 96 (12V or 24V). A household AC power supply of 100V may be used for this power supply portion 9c.

[0042] The actual amount of winding is about 20 cm to about 30 cm (distance Q), and a winding force of about 100 kg is required. The initial torque is quite large, and in particular, an initial force is required to curve the entire longitudinal direction of the rectangular main plate 1 made of a thin metal plate according to the present invention. A start button (not shown) is provided at the front position of the small hoist 9, and the moment the start button is pressed, the machine is driven to shorten the tension string-like object 4, and when a predetermined length has been shortened (wound up), a brake is automatically applied, and the rectangular main plate 1 is fixed while being curved in the longitudinal direction (X direction) as shown in FIG. 12(B).

[0043] [Actual usage of the present invention: Electric operation example] In the case of the electric type, since no human power is required for operation and the small hoisting machine 9 is provided, it is not vertical, but is placed horizontally in everyday life as shown in FIG. 12(A), and in the event of an actual major earthquake, the start button of the small hoisting machine 9 is pressed to instantly drive it and perform a shortening operation on the tension string-like object 4 to shorten (wind up) a predetermined length (distance Q), and a brake operation is applied to automatically stop it, and the longitudinal direction (X direction) of the rectangular main plate 1 is curved and fixed. Then, the body is protected in a prone position inside the curved rectangular main plate 1. In this way, it actually takes several seconds (about 3 to 6 seconds) from pressing the start switch to lying prone inside the rectangular main plate 1.

[0044] [Material mechanics, structural mechanics and mechanical considerations of the present invention] [No. 1] This is an idea to configure the rectangular main plate 1 in a flattened curved shape during normal times, while making the entire longitudinal direction of the rectangular main plate 1 curved (three-dimensional) during a major earthquake, and as one example, in the case of an S-type with a total height of about 205 cm in the X direction and a width of 90 cm in the Y direction, it is possible to obtain a mechanically efficient operation in which the maximum curved height P in the Z direction can be increased to a maximum of about 60 cm as a three-dimensional shelter by simply pushing down the X direction by about 25 cm (distance Q). In other words, a shortening operation of just over 25 cm (distance Q) in the X direction can obtain a curved three-dimensional object with a maximum curved height P in the Z direction approximating to about 60 cm.

[0045] For the M type, if the total height in the X direction is about 210 cm and the width in the Y direction is about 100 cm, then by simply pushing down the X direction by about 30 cm (distance Q), a three-dimensional shelter with a maximum curved height P in the Z direction of up to about 70 cm can be created. For the L type, if the height in the X direction is about 220 cm and the width in the Y direction is 110 cm, then by simply pushing down the X direction by just under 35 cm (distance Q), a three-dimensional shelter with a maximum curved height P in the Z direction of about 75 cm can be created.

[0046] [First conclusion] This is based on the condition that the length in the Y direction is about 90 cm and the length in the X direction is about 170 to 180 cm. If the distance Q in the X direction to be pressed down is the maximum height P that bulges out in the Z direction, then Distance Q<distance P There is a formula that says this.

[0047] This formula is a relational expression between the distance Q in the longitudinal direction of only the rectangular main plate 1, which includes the height of the end raised portion 2 of 25 cm to 35 cm, and the distance P in the Z direction of only the rectangular main plate 1. In other words, this invention takes into consideration the advantage that the distance P of the bulge in the Z direction is greater than the distance Q in the direction of depression (X direction). As a specific example, the S type and M type are depressed about 25 cm to 35 cm (distance Q) in the X direction, and a maximum height in the Z direction of about 40 cm + 30 cm (distance P) is obtained. Also, the L type is depressed about 35 cm (distance Q) in the X direction, and a maximum height in the Z direction of about 45 cm + 30 cm (distance P) is obtained.

[0048] [Second] The bending moment M is as shown in Figure 9(A): EI: bending strength 1 / ρ: Curvature of the deflection curve ρ: radius of curvature E: Modulus of elasticity M = (EI) × 1 / ρ (1)

[0049] The bending stiffness EI is determined by the material and cross-sectional shape of the metal material. In particular, the present invention proposes that the rectangular main plate 1 is flattened in normal times, but curved (three-dimensional) in a large earthquake. In particular, in a thin metal plate with excellent elasticity, the bending moment M is maximized when it is bent (from an instant to about several minutes), and at this time, as shown in Fig. 9(B), when the ceiling members (including beams) fall when the house collapses, it can withstand the falling load.

[0050] Specifically, elastic forces act from each part of the curved rectangular main plate 1 made of thin metal plate, and when observed moment by moment in detail, even if it becomes dented due to its elasticity, it bounces back irregularly and becomes strong enough to withstand the falling force when the house collapses, and the body can be hidden and protected inside the rectangular main plate 1 that becomes curved and expands in the Z direction and becomes three-dimensional. This is merely an assumption, and experiments are pending, and it is possible that it could withstand a falling load of several tons when the house collapses, although it depends on the quality of the metal material.

[0051] [Third] The bending stiffness EI is affected by the cross-sectional shape of the metal material, specifically in terms of material mechanics and structural mechanics. When viewed as a rectangular cross section of the metal material, it is shown in the upper part of Figure 12(B), but even if it is made into a thin plate as in the present invention [lower part of Figure 12(B)], it is expressed by the same section modulus Z. In other words, Z = b × (t squared) × 1 / 6 (2) According to formula (2), the section modulus is proportional to the square of the plate thickness. Therefore, if the plate thickness is doubled, the section modulus Z becomes four times as large. This means that even if the patented invention were made from a metal plate with a thickness of about 1.2 mm, it would weigh about 20 kg, making it difficult to handle.

[0052] [Safety measures for the rectangular main plate 1 made of thin metal plate and the raised portions 2, 2 at both ends] The rectangular main plate 1 is a thin metal plate, but since there is a risk of injury if handled with bare hands, decorative frame material 15a with a U-shaped cross section is provided around the long sides 11, 11 of the plate and the periphery of the end raised portion 21 with adhesive or the like to protect the plate, as shown in Fig. 6(A). Furthermore, corner pieces 15b as shown in Fig. 6(B) are provided at corners 22 of the end raised portion 21, and while being elastic, act as a base when placed vertically (see Fig. 1(A)) or horizontally (see Fig. 16(A)). It is preferable that corner pieces 15b are provided with an anti-slip treatment.

[0053] [3 types of rectangular metal thin plate main panel 1] Figure 10(C) shows an S-type elevation of the rectangular main panel 1 and the raised portions 2, 2 at both ends, with a height in the X direction of approximately 205 cm and a width in the Y direction of approximately 90 cm. Figure 10(D) shows an M-type elevation of the rectangular main panel 1 and the raised portions 2, 2 at both ends, with a height in the X direction of approximately 220 cm and a width in the Y direction of approximately 95 cm. Figure 10(E) shows an L-type elevation of the rectangular main panel 1 and the raised portions 2, 2 at both ends, with a height in the X direction of approximately 225 cm and a width in the Y direction of approximately 100 cm.

[0054] [Example of embodiment] A metal plate is used as a rectangular main plate 1 (without the raised portions 2 at both ends) with a thickness of 0.8 mm, a long side 11 of 90 cm, and a short side 12 of 45 cm. In order to provide a tensioning cord-like member 4 and make it curved, a considerable force is required to shorten the tensioning cord-like member 4. Here, it is important to note that even if the material is the same, if the plate thickness is increased even slightly, the strength is affected by the section modulus, so that it is the square of the plate thickness t. For example, the thickness is calculated as 0.8 x 0.8 = t squared, and t (the desired plate thickness) is about 1.13 mm, specifically, the commercially available plate thickness is 1.2 mm. In other words, in order to double the bending moment force M of a metal material with a thickness of 0.8 mm, it is possible to obtain a plate thickness of 1.2 mm, which is 50% thicker, because it affects not only the bending stiffness EI but also the section modulus Z.

[0055] [Made of FRP materials] Also, the explanations up to now have been of thin metal plates (steel, stainless steel, etc.), but this material has been changed to an FRP member (fiber reinforced plastics) as shown in Figures 13 and 14. Even with this FRP member, the manpower required to curve it from the state in Figure 13(A) to the state in Figure 13(B) is expected to be the same as that for thin metal plates (steel, stainless steel, etc.) (approximately 35 kg to 70 kg).

[0056] As for size, in the manual type of FRP member, θ3 is set to about 135 degrees (θ2 is about 45 degrees) in advance, the total length in the X direction is about 220 cm, and the width in the X direction is about 100 cm, as shown in Fig. 13(A), and tension string-like members 4 are provided in the same manner as the above-mentioned metal thin plate (steel, stainless steel member, etc.). Furthermore, the hook portion 5, magnetic member 6, and attraction member 7, which are shortening operation members S, are provided via a pull handle 81 in the same manner as the members shown in Figs. 3 and 4.

[0057] In addition, as shown in Fig. 14(A), the electric type of FRP member has a width in the Y direction of about 100 cm and a height in the X direction of about 220 cm, and is provided with tension strings 4 in the same manner as the above-mentioned metal thin plate (steel, stainless steel, etc.). In particular, like the small hoist 9 shown in Fig. 12, it is configured to be able to hoist with about 100 kg, and the rectangular main plate 1 of the FRP member is configured to be curved and fixed with the hoisting force of about 100 kg.

[0058] Also, although it has been explained that the rectangular main plate 1 of the FRP member is formed so that the width in the Y direction is about 100 cm and the height in the X direction is about 220 cm, it may be formed to the same size as the S type shown in Fig. 10(D), the M type shown in Fig. 10(E), or the L type shown in Fig. 10(F), which are examples of sizes of the rectangular main plate 1 of the metal thin plate described above. In particular, in Fig. 14(A) and Fig. 14(B), it is formed so as to be bent by about several degrees in the longitudinal direction (X direction), but this is included in the definition of a flat shape.

[0059] [How to hang "Noren 85" on a daily basis] The one shown in Fig. 11(B) is a "curtain 85" for daily use, with a total width equal to the total width in the Y direction of the rectangular main panel 1, and with one or more splits 85a. As shown in Fig. 11(A), the curtain 85 is intended to be hung on the upper half of the curtain placed vertically in daily use as a wall painting or decorative picture. It is particularly important that the pull handle 81 is located directly behind the split 85a. This allows the pull handle 81 to be grasped reliably while checking the split 85a in the event of a major earthquake, which may occur at any time.

[0060] The one shown in FIG. 11(C) is an electric type of the present invention, which is usually placed horizontally and has a curtain 85 hung over more than half of the upper side to serve as a wall picture. In this case, what is necessary is that the position of the split portion 85a be aligned directly in front of the start switch of the small hoist 9 so that the start switch can be pressed immediately.

[0061] The slit 85a of the curtain 85 shown in FIG. 11(C) is provided as necessary. The design drawn on the curtain 85 is not limited to the family crest, a favorite painting, or various character drawings, and can be anything that can be used for decoration. The reason is that during everyday life, the main frame part of the rectangular main board 1 is covered with the decorative curtain 85, providing a safe and secure way to spend your daily life, but in the event of a major earthquake, this frame can also play a major role as a body shelter.

[0062] In normal use, the entire length of the rectangular main plate 1 is formed flat, and the raised portions 2, 2 at both ends are provided at an incline, so that the tension string-like object 4 acts like a bowstring and is positioned above the position of the rectangular main plate 1, and the middle position of the tension string-like object 3, which is the string, is pulled by a fastener 87, as shown in 11(D). The fastener 87 is provided with a stopper 87a for the tension string-like object 3, and a magnet portion 87b when the rectangular main plate 1 is made of steel, which is a thin metal plate, and is fixed to the approximate center of the rectangular main plate 1 with an appropriate adhesive or pin, etc., when the rectangular main plate 1 is made of stainless steel.

[0063] In this specification, it has been clearly explained that the end raised portion 2 is the same material as the rectangular main plate 1, but it may be a separate metal material or a non-metal material such as wood, etc. This is determined appropriately based on issues of manufacturing cost and strength.
