JPS6215196A - Automatic expansion type lifesaving tool - Google Patents

Abstract

PURPOSE:To obtain an automatic lifesaving tool which springs out through expansion when a case is landed onto the water by using a water-weak paper- like material which is changed to be released from the bundle by water and a spring which is kept in compressed state by the paper-like bundling article. CONSTITUTION:When a case is landed onto the water, a suction value is opened by the water pressure, and water intrudes into the case, and further intrudes into the bored part of an outer cylinder 10, and permeates into a bundling body in water-weak paper form which is wound onto the top edge of a stop pin 6. Therefore, the bundling body is cut, and a spring 4 extends in a moment, having an operating lever 13 as basic board, and pushes up a seat metal 5, and a sticking needle 17 pierces a sealing plate 19. The gas inside the sealing plate 19 is introduced into a lifesaving tool, passing through the groove on the sticking needle 17 and a through-hole 21, and the lifesaving tool is expanded. The expanded lifesaving tool opens the cover of the case by the expansion force and is floated up onto the water. Since the lifesaving tool is automatically expanded only by the intrusion of water, the lifesaving tool is suitable for children and the old ages, of course for fishermen and on-water workers.

By using a spring that is kept compressed by a water-weak paper-like material, the paper-like material whose strength suddenly decreases when submerged in water is maintained in a compressed state, and the elastic force when the spring is released automatically It was designed so that it could be done. In place of the manual activation system of the conventional life preserver inflation device, the present invention provides a bottom plate and a groove in which a stop pin is fitted at the tip of the bottom plate, and the other end of the groove is formed into a tapered part. Insert the shaft into the spring and washer, press the spring and washer to the bottom plate and fitting groove, fit the stop pin, and bind both ends of the stop pin with water-weak paper-like material. A power source device with a highly compressed spring is installed inside the outer cylinder, and a filling device is installed in the life preserver, which operates the ejection needle by the expansion of the spring toward the sealing plate of the pressurized gas cylinder.It can be folded into a small size. Then, store it in a case and attach the case to your waist belt to carry it around.
