Description

Technical Field

[0001] The present invention relates to a plate-shaped structure having a float structure placed in a parking lot or the like.

Background Art

[0002] Japan is one of the most earthquake-prone countries in the world and is also an island country. Therefore, the damage caused by tsunamis associated with earthquakes is not negligible.

[0003] In March 〖=2011〗, the Great East Japan Earthquake, including the earthquake off the Pacific coast of the Tohoku region and the resulting tsunami, caused huge damage. Recently, countermeasures against tsunamis have become increasingly important.

[0004] In addition, the Nankai Trough Earthquake, which is said to affect many regions, is predicted to occur with a probability of 70% to 80% within 30 years from now. Disaster reduction measures, including those for tsunamis in the Nankai Trough Earthquake, have become important.

[0005] Under such circumstances, for example, recently, there is known a floating building that can be lifted upward by buoyancy without performing operations related to the floating of the float when a tsunami is generated by an earthquake (for example, Patent Document 1).

Summary of the Invention

[0008] Furthermore, the system described in Patent Document 1 has a limited range of movement within the building, and there is a possibility of being caught in rubble or sediment generated by tsunamis or floods, or in fires that occur after a tsunami.

[0009] This invention was made to solve the above problems, and is a plate-type structure with a float structure that can secure a safe space with the primary goal of saving lives in the event of a water disaster such as a tsunami by using a vehicle that is readily available. [Means for solving the problem]

[0010] (1) In order to solve the above problems, the present invention is A plate-type structure that is placed in a parking lot and has a float structure that can float on the water surface in the event of a disaster, and is composed of a plate on which a vehicle is mounted, A plate portion having a given thickness and on which the vehicle is mounted, The upper surface of the plate portion is provided with tire guide portions formed at both ends in the short direction, along the longitudinal direction of the plate portion, A wheel stop portion is formed at one end in the longitudinal direction of the upper surface of the plate portion, When the aforementioned disaster occurs, a given gas is injected, causing it to expand and forming a float portion around the vehicle mounted on the plate portion, Equipped with, The aforementioned plate portion, It has a configuration that functions as a hull when surfaced and has a multihull structure in which two or more hulls are connected in parallel.

[0011] With this configuration, the present invention allows the vehicle to float to the water surface by buoyancy while remaining mounted on the vehicle, even in the event of a disaster such as a flood, and then float freely and stably thereafter.

[0012] In other words, the present invention can be easily installed in a parking lot of a home or facility, and simply by installing it, it can function as a parking lot without any sense of incongruity during normal times, and in the event of a disaster such as a flood, it can float the vehicle on the water surface, protecting not only the vehicle but also the occupants inside the vehicle.

[0013] Therefore, the present invention makes it possible to easily provide a safe space with the primary objective of saving lives using a vehicle.

[0014] In addition to water-related disasters such as tsunamis and floods, the term "disaster" generally includes other types of disasters such as typhoons and landslides.

[0015] Furthermore, "float structure" simply means a structure that can obtain buoyancy exceeding the weight of the vehicle (including the weight of the passengers).

[0016] Furthermore, the "plate portion on which a vehicle is mounted" refers to a shape that allows a vehicle to be loaded onto it by self-propulsion or other means during normal times when no disaster occurs. For example, if a space is formed in the center, or if a plate surface is formed in the area where the tires run, the shape is not limited. However, since the plate portion is used to mount a vehicle, it is preferable that it be rectangular in shape.

[0017] Furthermore, "formed around the vehicle mounted on the plate portion" includes, for example, whether it is formed around the entire perimeter of the vehicle, or not around the entire perimeter, but at regular intervals.

[0018] In addition to the above, "a multihull structure in which two or more hulls are connected in parallel" refers to a structure in which, when surfaced, the vessel consists of multiple hull sections arranged side by side, each functioning as a hull (lower hull), such as a catamaran or trimaran, and these hull sections are connected above the water surface.

[0019] In particular, it is preferable that the plurality of body portions arranged side by side are formed along the longitudinal direction of the plate portion and spaced apart from each other from the viewpoint of stability (resilience).

[0020] And the connecting portion connecting the plurality of body portions may be formed by a shape (i.e., a flat plate) for covering the plurality of body portions, or may be formed by a shape for connecting the plurality of body portions at both ends, the central portion, or both in the longitudinal direction, such as a shape for connecting a part of two body portions.

[0021] (2) Further, the present invention has the structure of a catamaran as the structure of the multi-hull, where the plate portion

[0022] With this configuration, the present invention can reduce the inclination when floating on the water surface and can float stably.

[0023] (3) Further, the present invention where the plate portion has a mounting portion for forming a mounting surface for mounting the vehicle, and as the structure of the multi-hull, when floating on the water surface, has a plurality of body portions having a shape in which they are arranged side by side with a space thereunder, and a connecting portion for connecting the plurality of body portions on the water surface.

[0024] With this configuration, the present invention can function as a catamaran in the event of a disaster, so that it can float stably on the water surface and can float stably on the water.

[0025] (4) Further, the present invention where the plate portion has a configuration in which the structure of the catamaran is formed by a space extending along the longitudinal direction with the center of the plate portion as a reference and a member surrounding the space.

[0026] With this configuration, the present invention can function as a catamaran when it surfaces, thus enabling it to surface stably and float stably on the water's surface.

[0027] (5) Furthermore, the present invention is The plate portion has a configuration in which, as part of the multihull structure, a first groove or opening is formed on the bottom surface, extending along the longitudinal direction and having an opening on the lower side.

[0028] With this configuration, the present invention can function as a multihull when surfaced, such as functioning as a catamaran if there is one first groove or opening, or as a trimaran if there are two first grooves or openings, thus enabling stable surfacing and stable floating on the water surface.

[0029] Furthermore, the "first groove or opening" only needs to be one or more, and is not limited to a specific number.

[0030] (6) Furthermore, the present invention is The aforementioned plate portion, A mounting section that forms a mounting surface on which the aforementioned vehicle is mounted, The hull section functions as the ship's hull when it surfaces, Composed of, The plate has a configuration in which a first groove or opening is formed on the bottom surface of the body portion, which is the bottom surface of the plate, along the longitudinal direction, with an opening on the lower side.

[0031] With this configuration, the present invention can function as a multihull when surfaced, such as functioning as a catamaran if there is one first groove or opening, or as a trimaran if there are two first grooves or openings, thus enabling stable surfacing and stable floating on the water surface.

[0032] (7) Furthermore, the present invention is The body portion is provided with an attachment connected to the first groove or the opening, which is a water flow direction changing attachment that increases the water flow flowing in from the first groove or the opening when the vessel floats to the water surface.

[0033] With this configuration, the present invention allows the structure to float smoothly using the force of the water flow when water flows into the underside of the plate section during a disaster.

[0034] Furthermore, while it is preferable that the "attachment" be formed at the center, center of gravity, or near thereto of the plate portion in order to generate buoyancy throughout the entire structure, this is not limited to cases where the structure can be stably floated.

[0035] (8) Furthermore, the present invention is The aforementioned water flow direction changing attachment, It has a conical shape, and one or more spiral-shaped channels are formed on the side surface of the cone shape.

[0036] With this configuration, the present invention can efficiently change the water flow that enters from the groove or opening into an upward flow when water flows into the underside of the plate during a disaster, thereby allowing the structure to float smoothly.

[0037] (9) Furthermore, the present invention is A second groove or opening, with an open bottom surface, may be formed in a part of each fuselage portion, extending from the outside to the inside of the fuselage portion along the short direction of the plate portion.

[0038] With this configuration, the present invention can function as a catamaran in the event of a disaster, and can stably surface and float on the water.

[0039] (10) Furthermore, the present invention is The aforementioned plate section is formed by connecting multiple pallets.

[0040] This configuration allows the present invention to be provided inexpensively by using simple materials.

[0041] (11) Furthermore, the present invention is The float portion is The plate portion is formed around the vehicle mounted on it and has a structure that is pressed against the vehicle by the water pressure applied to the float portion from the outside.

[0042] With this configuration, the present invention can protect a vehicle from obstacles while it is floating on the water surface by a float that can provide strong buoyancy, and can also secure the vehicle.

[0043] (12) Furthermore, the present invention is The float portion is In normal times when no disaster has occurred, the tire guide portion and the wheel stop portion are housed in a configuration that includes a second end, which is a different longitudinal end from the first end on the upper surface of the plate portion where the wheel stop is formed.

[0044] With this configuration, the present invention can eliminate the influence of the floating part during normal operation and function as a parking lot without any sense of incongruity.

[0045] (13) Furthermore, the present invention is The float portion is The gas chambers that supply the gas used for expansion have a subdivided structure.

[0046] With this configuration, the present invention can maintain the floating of the plate-type structure by generating buoyancy in other air chambers, even if a part of the float is damaged and unable to inflate.

[0047] (14) Furthermore, the present invention is The tire guide portion and the wheel stop portion are integrally formed, A water-stopping plate is formed at a second end, which is a longitudinal end of the upper surface of the plate portion that is different from the first end on which the wheel stop is formed, and which functions as an entrance for the vehicle.

[0048] This configuration allows the present invention to function as a parking lot without any sense of incongruity during normal times, while also preventing water from flowing in from the entrance. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0050] Embodiments of the present invention will be described below with reference to the drawings.

[0051] The embodiments described below are examples in which the plate-type structure of the present invention is applied to a life-saving device that uses a vehicle mounted in a parking lot and functions as a life-saving device in the event of a disaster (hereinafter also referred to as a "parking lot-mounted vehicle-mounted life-saving device").

[0052] Furthermore, while the disasters described in this embodiment basically include water-related disasters such as tsunamis or floods, other disasters such as typhoons or landslides may also be included. However, the life-saving device for vehicles installed in parking lots according to this embodiment is not limited to these disasters, as long as it is useful during a disaster.

[0053] [A] First Embodiment First, a first embodiment of the vehicle-mounted life-saving device for parking lot installation according to the present application will be described.

[0054] [A.1] Overview and configuration of a vehicle-mounted life-saving device installed in a parking lot. First, an overview and general configuration of the parking lot-mounted vehicle-mounted life-saving device 10 of this embodiment will be described using Figures 1 and 2.

[0055] Figures 1 and 2 are external perspective views of the parking lot-mounted vehicle-mounted life-saving device 10 in this embodiment, when a vehicle is mounted on it during normal times or during a disaster.

[0056] The parking lot-mounted vehicle-mounted life-saving device 10 of this embodiment is a plate-type structure (hereinafter also referred to as the "plate-type structure") having a life-saving device structure that utilizes a vehicle M, primarily for the purpose of enabling evacuees to protect their own lives in the event of a disaster. For example, in the event of a tsunami, it has a structure that allows the vehicle M to float and levitate freely while still mounted on it.

[0057] Furthermore, unlike tsunami evacuation boats or tsunami shelters, the parking lot-mounted vehicle-mounted life-saving device 10 of this embodiment is simply placed in the parking lot P during normal times without hindering the function of the parking lot, and has a configuration that can be provided at an affordable cost.

[0058] On the other hand, the parking lot-mounted vehicle-mounted life-saving device 10 of this embodiment has a configuration that allows for staying (or evacuating) within a vehicle M such as a private car or bus as the activity space, during flood damage caused by a tsunami or the like.

[0059] Specifically, as shown in Figures 1 and 2, the parking lot-mounted vehicle-mounted life-saving device 10 is placed in a parking lot P and is formed by a plate-type structure consisting of a plate on which a vehicle is mounted, and which has a float structure that can float on the water surface in the event of a disaster.

[0060] In particular, the parking lot-mounted vehicle-mounted life-saving device 10 has a structure that can obtain buoyancy exceeding the weight of the vehicle (including when occupants (i.e., evacuees) are on board).

[0061] Furthermore, the parking lot-mounted vehicle-mounted life-saving device 10 comprises a plate portion 20 having a given thickness on which a vehicle M is mounted, tire guide portions 30 formed along the longitudinal direction of the plate portion 20 at both ends 21 in the short direction of the upper surface of the plate portion 20, a wheel stop portion 40 formed at one end 22 in the longitudinal direction of the upper surface of the plate portion 20, and a float portion 50 that expands when a given gas is injected in the event of a disaster and is formed around the vehicle mounted on the plate portion.

[0062] Furthermore, the parking lot-mounted vehicle-mounted life-saving device 10 is shaped to have a catamaran structure (hereinafter referred to as "catamaran structure") when it floats on the water surface.

[0063] In particular, the parking lot-mounted vehicle-mounted life-saving device 10 has a catamaran structure that prevents it from capsizing even if it tilts (inclinates) while floating (a highly stable structure).

[0064] [A.2] Plate section Next, the plate portion 20 of this embodiment will be described using Figures 3 to 5, along with Figures 1 and 2 described above.

[0065] Figure 3 is an exploded perspective view of the parking lot-mounted vehicle-mounted life-saving device 10 in this embodiment, and Figure 4 is a top view illustrating the structure of the parking lot-mounted vehicle-mounted life-saving device 10 from the lower layer to the upper layer in this embodiment.

[0066] Figure 5 is an exploded perspective view (modified example) of the plate portion 20 of the parking lot-type vehicle-mounted life-saving device 10 in this embodiment.

[0067] The plate section 20 is formed in a shape that creates a catamaran structure when it floats on the water surface.

[0068] In particular, the plate portion 20 is shaped in a rectangular form so that it can be loaded onto the vehicle M to be parked during normal times when no disaster occurs, such as by driving itself.

[0069] Specifically, as shown in Figure 3, the plate portion 20 consists of a mounting portion 210 that forms a mounting surface 23 on which the vehicle M is mounted, two body portions 220 and 230 provided on the lower surface of the mounting portion 210 and having a shape that is spaced apart and arranged side by side when floating on the water surface, and a connecting portion 240 that connects the two body portions 220 and 230 on the water surface.

[0070] As shown in Figures 2 to 4, each fuselage section 220 and 230 is formed along the longitudinal direction of the plate section 20 and spaced apart from each other, from the viewpoint of stability (resilience).

[0071] The connecting portion 240 may be formed in a shape that covers the two fuselage portions 220 and 230 (i.e., a flat plate), or it may be formed in a shape that connects a part of the two fuselage portions 220 and 230, such as a shape that connects the two fuselage portions 220 and 230 at both ends in the longitudinal direction, in the middle, or both.

[0072] On the other hand, the body sections 220 and 230 and the connecting section 240 of this embodiment are formed by connecting a plurality of rectangular-shaped pallets 200.

[0073] In particular, the body sections 220 and 230 and the connecting section 240 have a shape that allows multiple pallets 200 to be arranged in a rectangular shape and connected, and on which a vehicle M is mounted.

[0074] Furthermore, a space R is formed in the center of the rectangular shape of the plate portion 20 to form a catamaran structure (Figure 4(A)). However, the shape of the plate portion 20 itself, including the space R, is not limited as long as a pallet 200 is formed in the area where the tires of the vehicle M run.

[0075] The pallet 200 is preferably made of ABS resin or FRP (fiber-reinforced plastic), and is a repurposed loading platform (a so-called flat pallet) used when transporting cargo by forklifts, for example. However, the pallet 200 is not limited to these materials as long as it can accommodate the vehicle M, and may also be made of metal such as aluminum or wood.

[0076] Furthermore, the spaces (gaps) in each pallet 200 are filled with foamed resin to provide buoyancy in the event of flooding (Figure 4(B)).

[0077] For example, each pallet 200 is 150 mm thick and has dimensions of 1100 mm to 1400 mm in length and 900 mm to 1100 mm in width. In the case of a passenger car or a truck of 2 tons or less, the plate section 20 is formed by arranging 12 pallets 200 side by side, with dimensions of 5 m in length and 3 m in width.

[0078] In the case of buses and large trucks, each pallet 200 is formed by arranging 24 pallets 200 side by side, resulting in a size of 12m in length and 4m in width.

[0079] On the other hand, in this embodiment, a second groove (for example, U-shaped) or opening may be formed in a part of each body portion 220 and 230 of the plate portion 20, from the viewpoint of stability (resilience), as shown in Figure 5, with the lower surface open, extending from the outside to the inside of the body portion 220 and 230 along the shorter direction of the plate portion 20.

[0080] Figure 5 shows an example where an opening OP is formed along the shorter direction of the plate portion 20, extending from the outside to the inside of the body portions 220 and 230.

[0081] [A.3] Tire guide section and wheel stop section, etc. Next, the tire guide section 30 and the wheel stop section 40 of this embodiment will be described using Figures 1 to 4 above.

[0082] As shown in Figures 1 to 4 above, the tire guide portion 30 is formed along the longitudinal direction of the plate portion 20 at both ends 21 in the short direction of the upper surface of the plate portion 20 when the vehicle M is mounted.

[0083] Furthermore, each tire guide section 30 has a given height (for example, 200 mm to 400 mm) and is fixedly installed on the upper surface of the plate section 20.

[0084] Each tire guide section 30 is provided to prevent the vehicle M from laterally removing the plate section 20 when the vehicle M enters the upper surface of the plate section 20 under normal circumstances, and to guide the parking position of the vehicle M in the width direction.

[0085] Furthermore, a float section 50 is embedded inside each tire guide section 30.

[0086] In particular, each tire guide section 30 has a configuration in which, in the case of a manual system in which the float section 50 is inflated by gas injection based on the operator's instructions, the lid opens based on the operation of the passenger (evacuee), and instead of the operator's instructions, the lid opens automatically if, for example, a certain amount of water is detected on the upper surface of the plate section 20.

[0087] Furthermore, each tire guide section 30 is configured such that, in the case of an automatic float section 50, its lid opens in conjunction with the injection of gas into the float section 50.

[0088] In this case, each tire guide section 30 may have a structure that allows its lid to open using the force of the expansion when the float section 50 expands, or it may have a mechanism that allows its lid to open mechanically when it receives instructions from an evacuee regarding the float section 50, or when it automatically detects water.

[0089] Alternatively, each tire guide portion 30 may be formed on the upper surface of the plate portion 20 at a position a given distance inward from the end portion 21.

[0090] Furthermore, it is preferable that the tire guide portion 30 is formed integrally with the wheel stop portion 40, but this is not limited to this.

[0091] As shown in Figures 1 to 4 above, the wheel stop portion 40 is formed on one end 22 in the longitudinal direction of the upper surface of the plate portion 20.

[0092] Furthermore, the wheel stopper section 40, like each tire guide section 30, has a given height (for example, 200 mm to 400 mm) and is fixedly installed on the upper surface of the plate section 20.

[0093] The wheel stop 40 is provided to prevent the vehicle M from coming off the plate portion 20 from the rear when the vehicle M enters the upper surface of the plate portion 20 under normal circumstances, and to guide the vehicle M to a parking position in the front-rear direction.

[0094] Furthermore, a float section 50 is embedded inside the wheel stop section 40, similar to the tire guide sections 30.

[0095] Furthermore, the wheel stopper section 40, like each tire guide section 30, has a configuration in which, in the case of a manual system in which the float section 50 is inflated by gas injection based on the operator's instructions, its lid opens based on the operation of the passenger (evacuee), and instead of the operator's instructions, if a certain amount of water is detected on the upper surface of the plate section 20, for example, its lid opens automatically.

[0096] [A.4] Float section Next, the float section 50 of this embodiment will be described using Figures 1 to 4 above.

[0097] As described above, the float section 50 expands when a given gas is injected during a disaster and forms around the vehicle M mounted on the plate section 20.

[0098] In particular, as shown in Figures 1, 2, and 4(E) and (F), the float section 50 is normally stored in the tire guide section 30 and the wheel stop section 40. In the event of a disaster, it expands when a given gas (for example, liquefied carbon dioxide) is injected, and emerges from the tire guide section 30 and the wheel stop section 40 to be installed around the vehicle M.

[0099] Furthermore, as shown in Figures 2 and 4(F), the float portion 50 is formed around the vehicle M mounted on the plate portion 20 and has a structure that presses against the vehicle by the water pressure applied to the float portion from the outside.

[0100] In particular, the float section 50 is used not only to provide buoyancy but also as a buffer to increase resistance to obstacles and floating debris.

[0101] For example, the float section 50 is made of high-strength nylon used in bulletproof vests and the like on the outside, and is constructed based on stitching to prevent the float section of the vehicle M from being crushed, and is composed of a rectangular prism shape with a diameter of about 90 cm.

[0102] Specifically, as shown in Figures 2 and 4, the float section 50 is composed of multiple air chambers 51 in order to limit the impact on the whole even if a part of it is crushed, and each air chamber 51 is formed independently of the other air chambers (air chamber 51a is independent of air chamber 51b or 51c).

[0103] In other words, the float section 50 has a structure in which the gas chambers to which the gas used for expansion is supplied are subdivided.

[0104] Furthermore, under normal conditions, the air chamber into which gas is injected is folded, and in this state, the float section 50 is stored in the tire guide section 30 and the wheel stop section 40.

[0105] Furthermore, each air chamber may be injected with a given gas based on the operation of an operator, such as an evacuee present in the room (i.e., manually), or it may be injected automatically upon detection of water (i.e., automatically).

[0106] The gas is stored in one of the plate sections 20 by a tank (not shown), such as a cylinder, and the tank and each gas chamber 51 are connected by a tube (not shown), etc.

[0107] Furthermore, when manually injecting gas into each air chamber, this is done by a switch (not shown) installed on the upper surface of the plate section 20.

[0108] Furthermore, in this embodiment, the float portion 50 is formed by multiple air chambers around the entire perimeter of the lower part of the vehicle M, but it may also be formed at regular intervals rather than around the entire perimeter.

[0109] [A.5] Drainage equipment etc. Next, the drainage device and other components of this embodiment will be described.

[0110] (Drainage device) The parking lot-mounted vehicle-mounted life-saving device 10 has a drainage device (not shown) and is configured to drain water that has seeped onto the plate portion 20 to the outside.

[0111] In particular, the drainage device (not shown) has a solar panel and is configured to be driven using electricity generated by sunlight.

[0112] (Waterstop plate) The parking lot-mounted vehicle-mounted life-saving device 10 has a water-stopping plate 80 of a predetermined height to prevent water from entering.

[0113] In particular, as shown in Figure 2, the water-stopping plate 80 is located at an end 24 different from the end 22 on which the wheel-stopping portion 40 of the plate portion 20 is formed, and is provided at the entrance where the vehicle M enters the plate portion 20.

[0114] Furthermore, the water-stopping plate 80 may also be provided in conjunction with a ramp used when entering the plate section 20.

[0115] (Mooring ropes and mooring rings) The parking lot-mounted vehicle-mounted life-saving device 10 may have mooring equipment and a configuration that prevents free floating depending on the situation, even in the event of a disaster.

[0116] Specifically, the parking lot-type vehicle-mounted life-saving device 10 includes, as mooring equipment, a mooring rope with one end fixed to the ground or another building (not shown), and a mooring ring to which the other end of the mooring rope is attached.

[0117] The mooring ring is fixedly installed at one of the locations on the plate section 20, and can be removed by the evacuee's instructions or operation, for example by removing a pin with a wire, thereby detaching the mooring ring itself and releasing the connection to the mooring rope.

[0118] [A.6] Total weight and buoyancy Next, the relationship between total weight and buoyancy in the parking lot-mounted vehicle-mounted life-saving device 10 of this embodiment will be explained.

[0119] The parking lot-mounted vehicle-mounted life-saving device 10 of this embodiment has a configuration in which the total buoyancy obtained by the plate portion 20 and the float portion 50 is greater than the total weight of the parking lot-mounted vehicle-mounted life-saving device 10.

[0120] In particular, if each pallet 200 weighs between 5kg and 25kg, and the weight of the mounting section 210 is 400kg (material: aluminum / 5m long x 3m wide / 3mm thick), then the weight of the plate section 20, including the tire guide section 30, will be a maximum of approximately 0.3t.

[0121] Furthermore, since vehicle M weighs approximately 2.0 tons, the maximum weight including passengers is approximately 2.5 tons.

[0122] On the other hand, the buoyancy of the plate section 20 having the pallet 200 is 1.5t, and the buoyancy of the float section 50 is also 1.5t, so the total buoyancy of the parking lot-type vehicle-mounted life-saving device 10 is 3.0t.

[0123] Therefore, since the total buoyancy is sufficiently large, the parking lot-mounted vehicle-mounted life-saving device 10 is able to float on the water surface in the event of a disaster.

[0124] [B] Second Embodiment Next, a second embodiment of the parking lot-type vehicle-mounted life-saving device according to the present application will be described.

[0125] [B.1] Overview and configuration of a vehicle-mounted life-saving device installed in a parking lot. This embodiment is characterized in that, in the first embodiment, instead of the catamaran structure in which two hull sections are connected, a multihull structure is adopted, and grooves or openings that open to the underside are formed on the bottom surface of the plate section, while the other configurations are the same as those of the first embodiment.

[0126] In particular, the parking lot-mounted vehicle-mounted life-saving device 10 of this embodiment has a multihull structure and includes a groove portion (first groove portion) with an opening on the lower surface side or a plate portion 20 with an opening formed on the bottom surface, along the longitudinal direction.

[0127] With this configuration, the parking lot-mounted vehicle-mounted life-saving device 10 of this embodiment can function as a multihull with a simple structure when the plate portion 20 floats on the water surface. Therefore, similar to the first embodiment, it can float stably on the water surface and stably afloat on the water surface.

[0128] [B.2] Plate section Next, the plate portion 20 of this embodiment will be described using Figures 6 to 8.

[0129] Figure 6 is an exploded perspective view of the parking lot-type vehicle-mounted life-saving device 10 in this embodiment, Figure 7 is a top view and side view of the plate portion 20 in this embodiment, and Figure 8 is a perspective view of the attachment 250 in this embodiment.

[0130] The plate portion 20 of this embodiment is formed in such a shape that, when it floats on the water surface, it forms a multihull structure (hereinafter also referred to as "multihull structure") due to the multiple first grooves GR.

[0131] In particular, the plate portion 20 of this embodiment is composed of a mounting portion 210 that forms a mounting surface for mounting a vehicle and a hull portion 221 that functions as a hull when floating on the water surface. An opening (hereinafter referred to as the "first opening") OP1 is formed on the bottom surface of the hull portion 221, which is the bottom surface of the plate portion 20, with an opening on the lower side, along the longitudinal direction.

[0132] Specifically, as shown in Figures 6 and 7, the plate portion 20 consists of a mounting portion 210 that forms a mounting surface 23 on which the vehicle M is mounted, a body portion 221 provided on the lower surface of the mounting portion 210 and having a first opening OP1 formed in the longitudinal direction of the plate portion 20, an attachment 250 for water flow conversion formed near the center of the plate portion 20, and an opening (hereinafter referred to as the "second opening") OP2 formed from the outside to the inside of the body portion 221 along the short direction of the plate portion 20, similar to the first embodiment.

[0133] As shown in Figures 6 and 7, the fuselage section 221 has a plurality of spaced-apart first openings OP1 formed along the longitudinal direction of the plate section 20, from the viewpoint of stability (resilience).

[0134] In particular, each first opening OP1 has an opening on the lower side and is formed linearly from one end (top) to the other end (tail) of the plate portion 20.

[0135] Furthermore, each first opening OP1 is connected to the attachment 250 and the second opening OP2 near the center (for example, the center position or the center of gravity position).

[0136] In this embodiment, two first openings OP1 are formed, as shown in Figures 6 and 7, but three or more may be formed and inserted.

[0137] Attachment 250, as shown in Figures 6 to 8, is an attachment connected to each first opening OP1, and is a water flow direction changing attachment that increases the water flow flowing in from the first opening OP1 when floating to the water surface.

[0138] Specifically, the attachment 250 of this embodiment is formed within a circular opening OP3 formed near the center of the fuselage portion 221 (for example, the center or center of gravity).

[0139] In particular, in order to cause the water flow that flows into the bottom surface of the attachment 250 to rise along the side surface of the attachment 250 from the bottom surface toward the bottom surface of the mounting section 210, the attachment 250 has a conical shape, and one or more spiral-shaped water channels WY are formed on the side surface of the conical shape.

[0140] Each waterway WY is formed by a given curved shape, and also by a spiral shape (i.e., a spiral shape) with the outer side being higher and the inner side lower.

[0141] On the other hand, the attachment 250 is integrally formed with a base 251 formed on the bottom surface of the attachment, and is fixed to the body 221 via a support column 252 provided at the corner of the base 251.

[0142] The size of the base 251 in this embodiment is not particularly limited, and it is sufficient if it is shaped in a way that allows the attachment 250 to be fixed to the body portion 221. However, it is preferable that the base 251 is formed without obstructing the waterway formed by the first opening OP1 and the second opening OP2.

[0143] Furthermore, in order to release the rising water flow and efficiently raise the water flow that flows into the attachment, a gap is provided between the top of the attachment 250 and the bottom surface of the mounting section 210.

[0144] Furthermore, the body portion 221 of this embodiment, similar to the first embodiment, has a shape for mounting a vehicle M on its upper surface, with a plurality of pallets 200 arranged in a rectangular shape and connected together, and a first opening OP1 and a second opening OP2 formed at appropriate positions.

[0145] In addition to the above, the plate portion 20 of this embodiment has a first opening OP1 and a second opening OP2, but instead of these openings, a groove portion with an open bottom surface (for example, U-shaped) may be formed.

[0146] [C] Other The present invention is not limited to the embodiments described above, and various modifications are possible. For example, terms cited as broad or synonymous in the specification or drawings may be replaced with broad or synonymous terms in other descriptions in the specification or drawings.

[0147] The present invention includes configurations that are substantially identical to those described in the embodiments (for example, configurations with the same function, method, and result, or configurations with the same purpose and effect). Furthermore, the present invention includes configurations in which non-essential parts of the configurations described in the embodiments are replaced. Furthermore, the present invention includes configurations that produce the same effects or achieve the same purpose as those described in the embodiments. Furthermore, the present invention includes configurations that add known technology to the configurations described in the embodiments.

[0148] As described above, embodiments of the present invention have been explained in detail, but it will be readily apparent to those skilled in the art that many modifications are possible without substantially departing from the novel aspects and effects of the present invention. Therefore, all such modifications are included within the scope of the present invention. [Explanation of Symbols]
