Patent ID: 7013809

Claim:
Improvements in electro-mechanical fuses for hand grenades, applicable to the types of fuse which comprise a container ( 9 ) which houses a movable slider ( 10 ) in which in turn is housed an electrical generator ( 1 ), which produces power required by the entire fuse, delivering it to an electronic circuit ( 11 ) which with a timed delay discharges it on a detonator ( 8 ) which detonation, through a multiplier ( 12 ) is transmitted to a main explosive charge of the grenade, the improvement fuse comprising: at least a first and a second electronic timers, the electronic timers being mutually independent electronic timers which can be one of configured, combined and preset independently from each other, acting sequentially for the final explosion of the hand grenade to occur, and wherein inside the movable slider ( 10 ) and laterally with respect to the detonator ( 8 ) is provided an expansion chamber ( 13 ) embodied in a bushing ( 14 ), at the top end of which is placed an electro-explosive actuator ( 15 ), while on its bottom end it houses a piston ( 16 ) integrally attached to a support ( 17 ) of the multiplier ( 12 ), so that when the slider ( 10 ) moves, the support ( 17 ) moves along with it, maintaining an unaligned arrangement of the multiplier ( 12 ) and the detonator ( 8 ), while a trip switch ( 19 ) keeps the detonator ( 8 ) short-circuited, preventing its initiation.
