Description

  The present invention relates to a vehicle submergence prevention device for reducing damage by wrapping a vehicle with a seat and floating it in water when the river overflows due to flooding or the like and the water level rises, thereby preventing the vehicle from submerging. Is.

  When a flood occurs due to river flooding due to heavy rain, vehicles such as automobiles may be submerged. If the vehicle is submerged and water enters the engine, an overhaul is required, and the electrical components are damaged by water and must be replaced. In addition, muddy water infiltrates the interior of the vehicle interior, causing the interior materials to become dirty and the interior of the vehicle to be cleaned, which requires significant costs for recovery.In many cases, the cost of recovery exceeds the vehicle price, and in most cases Becomes a scrapped car.

  Furthermore, for example, in the case of a special vehicle such as an ambulance, there are many cases where an expensive medical device or the like is mounted inside, and when this is submerged, it is not only a loss of the vehicle itself, but also a great economic cost. It often causes damage.

  Conventionally, there are some known examples of means for preventing the vehicle from being submerged. For example, Japanese Utility Model Laid-Open No. 61-189866 and Japanese Utility Model Laid-Open No. 5-46613 show that air bags are provided before and after a vehicle and inflated to prevent submersion.

  However, these are for gaining time for passengers to escape when the vehicle falls into the water, preventing water from entering the passenger compartment in the event of a flood, etc. Not enough to In addition, in order to equip the vehicle with an airbag, the vehicle itself needs to be extensively remodeled, and the vehicle must always be run with this equipment mounted, which is not realistic.

  Japanese Patent Application Laid-Open No. 2002-248946 describes means for preventing a vehicle from being submerged by completely wrapping the vehicle with a huge cylindrical sheet. However, in this method, the vehicle is covered with a cylindrical sheet and the opening thereof is closed, so that air is enclosed in the cylindrical sheet and there is no escape space for the air. Therefore, when the water volume increases, the tubular sheet itself may swell, and the closed opening may open or in the worst case, the tubular sheet may burst, preventing the vehicle from being submerged.

  In addition, the present invention covers the entire vehicle with a tubular seat and closes the opening thereof. Therefore, in order to close the opening of the tubular seat at the top of the vehicle, the working position is set at a high position on the top of the vehicle. It must be set, and when a vehicle is inserted from the side of the tubular seat, special equipment for keeping the tubular seat open is necessary, which is once every several to several tens of years. To prepare for the situation, it costs a lot of money and is not realistic.

  In view of this situation, when there is a risk of flooding due to flooding, the bottom and side of the vehicle are wrapped in a water-tight sheet, and when the water level rises, the vehicle is lifted by the buoyancy of the vehicle's internal space to prevent flooding Has been filed as Japanese Patent Application No. 2006-147606.

  As shown in FIG. 1, the present invention wraps the lower part and the lower part of a side surface of a vehicle 2 with a water-tight sheet 1 when a flood is predicted. In addition, the internal space of the vehicle 2 is secured even when the water level rises, and the vehicle 2 is levitated on the water 8 as shown in FIG. is there.

  However, in this method, the seat 1 is spread to the storage location of the vehicle 2, the vehicle 2 is moved onto the seat 1, and the vehicle 2 is wrapped along the periphery of the seat 1 along the side surface of the vehicle 2. When the vehicle 2 is moved onto the seat 1, in order to finely adjust the position of the vehicle 2 on the seat 1, it is necessary to rotate the steering wheel while the vehicle 2 is stopped on the seat 1. There are many.

  In general, an automobile tire has a high frictional resistance for gripping a road surface. When the vehicle tire is stationary on the seat 1, the seat 1 rotates together with the tire while being strongly pressed against the ground, and the seat 1 is locally grounded. In some extreme cases, it may be worn away, or in extreme cases, a hole may be formed and water tightness cannot be ensured.

  The present invention has been made in view of such circumstances, and is a vehicle submergence prevention tool used in the above-described method, and even when the vehicle 2 is stationary on the seat 1, the seat 1 may be damaged. The purpose is to reliably prevent the vehicle 2 from being submerged.

Thus, the present invention provides a vehicle submergence prevention device that wraps the bottom of the vehicle and the lower side of the vehicle with a watertight seat to prevent the vehicle from being submerged. A multi-layer having a watertight intermediate layer, a lower layer in contact with the ground and an upper layer in contact with the tire, which are respectively stacked above and below the intermediate layer, and the peripheral portions of the upper layer and the lower layer are integrated with the intermediate layer. In addition to joining, the upper layer is free from the lower layer.

Moreover, in this invention, it is preferable to join the said upper layer or lower layer so that attachment or detachment is possible from an intermediate | middle layer.

In the present invention, it is preferable that a lubricant is interposed between the upper layer and the lower layer and the intermediate layer.

In addition, it is also preferable to use a material having a low frictional resistance or to perform a surface treatment with a low frictional resistance on the facing surface between the upper layer and the lower layer and the intermediate layer.

  According to the present invention, at least the place where the tire of the vehicle is placed is multiplexed, and the upper layer is separated from the lower layer, so when the vehicle is placed on it and the handle is fixed, The upper layer rotates with the tire, but slipping occurs between multiple layers, so that the lower layer does not move relative to the ground, and the seat does not wear or perforate. It is possible to reliably prevent the submergence of water.

Partial enlarged sectional view of another example of the vehicle submersion prevention device of the present invention

  The present invention will be described below with reference to the drawings. FIGS. 3 and 4 show an example of the vehicle submersion prevention device 3 according to the present invention. The vehicle submersion prevention device 3 is composed of a two-layer sheet composed of an upper layer 4 and a lower layer 5, and the upper layer 4 or the lower layer 5. At least one of them is watertight, and the upper layer 4 is free from the lower layer 5 and is bonded to the lower layer 5 at the peripheral edge of the upper layer 4.

  In the present invention, the vehicle submergence prevention device 3 is spread on the ground, the vehicle 2 is moved thereon, the vehicle 2 is stopped at the center of the vehicle submergence prevention device 3, and the vehicle submergence prevention device 3 is surrounded in this state. Pull up to wrap the side of the vehicle 2.

  At this time, in order to finely adjust the position of the vehicle 2 on the vehicle submergence prevention device 3, if the steering wheel is fixed while the vehicle 2 is stopped on the vehicle submergence prevention device 3, the upper layer 4 in contact with the tire 6 of the vehicle 2. Rotates with the tire 6 and the sheet of the upper layer 4 is locally twisted, but the upper layer 4 is separated from the lower layer 5, so that only the upper layer 4 rotates and the lower layer 5 rotates due to frictional resistance with the ground. And does not rub against the ground.

  In addition, after the steering wheel is stationary, the vehicle is moved back and forth, so that the deformation of the seat of the upper layer 4 is restored by its elasticity and the twist of the seat is eliminated. Therefore, the vehicle 2 is smoothly wrapped using the seat. be able to.

  The upper layer 4 and the lower layer 5 need to be slippery with each other, but the upper layer 4 and the tire 6 have a large frictional resistance due to the grip of the tire 6, and the lower layer 5 and the ground have a particularly smooth ground. Except for the case, the frictional resistance is generally large, so that it is not necessary to provide special means for making the upper layer 4 slippery with respect to the lower layer 5.

  However, it may be particularly slippery, such as when the ground is wet, and it is preferable to take measures to reduce the frictional resistance between the upper layer 4 and the lower layer 5. For example, it is preferable that a powder such as talc or carbon or a lubricant such as a liquid with high viscosity be interposed between the upper layer 4 and the lower layer 5. Further, surface processing for reducing frictional resistance can be applied to the lower surface of the upper layer 4 and the upper surface of the lower layer 5.

  In addition, the range in which the upper layer 4 and the lower layer 5 of the vehicle submersion preventer 3 are overlapped is a range where at least the vehicle 2 in the center of the vehicle submergence preventer 3 is placed. In order to adjust the position, the position may be changed back and forth and left and right, and the handle may be fixed at that position, so it should be as wide as possible.

  Moreover, it is preferable to join the upper layer 4 and the lower layer 5 at the periphery of the vehicle submersion prevention device 3. As the means for joining, the upper layer 4 and the lower layer 5 can be stitched together, and can be detachably connected by appropriate means such as a hook-and-loop fastener, a slide fastener, a button, a hook, and the like.

  FIG. 5 shows another example of the present invention, in which an upper layer 4 and a lower layer 5 are stacked on both sides of a watertight intermediate layer 7 to form three layers. By making three layers, slip occurs between the upper layer 4 and the intermediate layer 7 and between the intermediate layer 7 and the lower layer 5, so even if the upper layer 4 is twisted along with the tire 6, The twist is not transmitted to the lower layer 5, and the possibility that the lower layer 5 is worn due to friction with the ground is further reduced.

  In this case, the upper layer 4 and the lower layer 5 may be damaged by friction with the tire 6 or the ground, but the intermediate layer 7 is protected by the upper layer 4 and the lower layer 5 and is less likely to be damaged. The upper layer 4 and the lower layer 5 are preferably detachably coupled to the intermediate layer 7. In this case, the upper layer 4 and the lower layer 5 may be made of a material having low durability such as a non-woven fabric and may be used only once.

  In the present invention, in the above example, the case of two layers of the upper layer 4 and the lower layer 5 and the case of three layers of the upper layer 4, the lower layer 5 and the intermediate layer 7 are mentioned, but the present invention is not limited to this. It is also possible to make four or more layers. In addition, at least one of the two or more layers needs to be watertight, but the other layers need not be watertight.
