Self destructing fuse for sub-munitions to be expelled from a rocket

A fuse for sub-munitions which can be ejected from a projectile, comprising a first striker member movable within the body of the fuse in the direction of its longitudinal axis to come into contact with a detonator to cause it to explode, a slide which is movable within the said body in a direction substantially orthogonally of that of the said axis and which carries the said detonator, the said slide being movable from a first position in which the said detonator is located out of the path of the said first striker member and to one side thereof, to a second position in which the said detonator is located in the said path, the said striker member being movable from a first position, in which the lower end thereof is inserted in a corresponding seating of the said slide to prevent its movement, to a second position in which the said end is withdrawn from the said seating, in such a way as to allow movement of the said slide, characterised by the fact that it includes a second striker member movable within the said slide from a first position, in which it resiliently deforms a spring and is held at a predetermined distance from the said detonator, to a second position in which it comes into contact, by the action of the said spring, with the said detonator to cause it to explode, the said second striker member being held in the said first position by the action of the said first striker member when the said slide is located in the said first position and the movement of the said second striker member being delayed by delay means operable to allow the movement of the said second striker member from the said first to the said second position after a predetermined time from the instant in which the said slide has reached the said second position.
