Patent ID: 8408134

Claim:
A hand grenade fuze, comprising: a firing cap; a delay charge holder; a delay charge which can be fired by said firing cap and disposed in said delay charge holder; a detonator holder; a detonator which can be fired by said delay charge, said detonator disposed in said detonator holder; a booster charge which can be fired by said detonator, for firing a hand grenade explosive charge; said detonator holder configured such that said detonator holder can pivot, and said delay charge holder, when disposed in a first position, blocks a pivoting movement of said detonator holder in a rest position, in which said detonator is not disposed in line with said booster charge and said delay charge, such that burning of said delay charge cannot fire said detonator, and detonation of said detonator cannot fire said booster charge; and said delay charge holder is held in the first position by a connection which can be released by heat, wherein the connection which can be released by heat is disposed such that burning of said delay charge results in the connection which can be released by heat being released and, under an influence of a force action, results in said delay charge holder assuming a second position, with a blocking of the pivoting movement of said detonator holder being cancelled, thus resulting in said detonator holder being pivoted from the rest position to an activation position, as a result of which said detonator is disposed in line with said booster charge and said delay charge, in that said detonator is fired by a burning of said delay charge, and a detonation of said detonator fires said booster charge.
