PROBLEM TO BE SOLVED: To solve the problem that passengers are confined in a car to be drowned because the doors would not be opened due to enormous water pressure to the doors when the car is submerged conventionally.SOLUTION: When an automobile is submerged, if a passenger grips a handle and has only to open a lid, a large amount of water automatically flows into the car even if the hand is separated. Thus, water is caused to suddenly flow into the car even if the automobile is submerged. Then, water pressure applying to a door is rapidly weakened to turn out to be finally a zero. The passenger can evacuate in safety by opening the door without waiting for the car to be filled with water. Since water pressure applying to the door acceleratingly decreases as a water level in the car continuously rises if the door is continuously pushed. The passenger can evacuate without waiting until the water pressure becomes zero (when the water level in the car becomes equal to the water level outside the car) because the danger of submergence is drawing near with every moment.SELECTED DRAWING: Figure 1
【課題】 従来、車が水没すると、ドアに強大な水圧がかかるため、ドアを開けられず、そのため、車内に閉じ込められて溺死する。【解決手段】 自動車が水没した時、とっ手を持って蓋を開けさえすれば、後は、手を離しても大量の水が車内に自動的に流れ込むように構成した。これにより、自動車が水没しても、車内に水がドットと流れ込む。したがって、ドアが受ける水圧は急激に小さくなり遂には零となる。しかし、脱出は、水圧が零(車内の水位が車外の水位と同じになった時)になるまで待つのではなく、水没の危機は刻一刻と迫るので、ドアを押し続ければ、車内の水位は上昇し続け、それにつれて、ドアが受ける水圧は加速度的に減じていくので、水が車内に充満するを待たないで、ドアを開けて無事脱出することができる。【選択図】図1
