Title:
ESCAPE DEVICE BY FREE FALL DESCENT OF LIFEBOAT
Document Type and Number:
Japanese Patent JP3239208
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To surely escape from a mother ship in safety by providing at least two support parts of a lifeboat with a structure where they glides the same distance.
SOLUTION: The front and rear two stage sliding ways 4, 5 provided on a mother ship, have the height same as that of two support parts 2, 3 before and behind a center of gravity, are in parallel with each other, and have the same length. Further the support parts 2, 3 are set so that they glide the same distance and simultaneously start the free fall descent by released in the air. A lifeboat which starts its free fall descent after the gliding, continues its free fall descent while keeping an angle at the instant when it is transited to the free fall descent, so that it is lunched with the angle to be transited to the inertial travel on the water surface. On this occasion, the supports parts before and behind the center of gravity are simultaneously separated from the sliding ways to start the free fall descent, so that the free fall descent and the launching are performed while keeping the angle same as the sliding way inclination angle. Accordingly by properly selecting an inclination angle of the sliding way in the design of the device, the lifeboat to be launched can be provided with a proper launching angle, whereby the escrape from the mother ship can be surely performed in safety.
