Abstract
A triggering device intended to be actuated upon being immersed in water uses a force-transmitting member of variable length in the form of an array of collapsible struts restrained from folding, and hence triggering the device by at least one tensile member of which the strength reduces greatly when wetted.
Claims10
An immersion-actuated triggering device, including two members resiliently biassed towards each other but held apart by means of two or more folding struts extending between the members and kept in compression by the biassing force, the struts being kept in an elongated position by means of the tensions in one or more pieces of a material of which the tensile strength reduces greatly when it is wetted, whereby the struts collapse by folding outwardly when the material is wetted, the resultant relevant movement of the two members towards each other being effective to
