Title:
浮揚装置
Document Type and Number:
Japanese Patent JP2009525226
Kind Code:
A
Abstract:
A device which will act efficiently as a float for any article (e.g. keys, mobile telephone, wallet) attached thereto when dropped into water comprises an inflatable bag (14') of substantially waterproof and air impervious material, a container (12) of compressed gas, and trigger means (16,30,32) associated with the container (12) and operable upon immersion of the device in water to open the container (12) and allow gas from the container (14') to inflate the bag (14). The trigger means comprises a valve (16) mounted on the container (12) and connecting the container to the inflatable bag (14'), retainer means (64) operative to hold the valve (16) in a closed condition, and water reactive means (66) which, upon contact with water, serves to release the retainer means (64) and allow the valve to open, e.g. under spring bias. The water reactive means may comprise a band of material (66), at least part of which is water reactive. The bag (14'), the container (12) and the trigger means are housed in a casing (10) and means (37) are provided, preferably integrally on the container (12), for attachment of the device to another article. An illumination device (50) is mounted inside the inflatable bag (14'). This preferably includes a light emitting diode (LED) (52) powered by at least one battery (54), the latter being automatically connected to the LED upon inflation of the bag by withdrawal of an intervening strip of insulating material.
