Abstract

The fuse provides safety against striking objects before the effluxion of the predetermined arming period and comprises a fixed striker 17, a slidable detonator 14, a locking ball 28 and two inertia sleeves 21, 22 separated by a spring 25. When the grenade is fired, the sleeve 21 sets back and, upon the cessation of acceleration, moves forward under the action of spring 25 to relase the ball 28 with a delay determined by the engagement in a zig-zag groove 24 of a pin 23 extending from the sleeve 21. If the grenade should strike an obstacle before the sleeve 21 has moved sufficiently far fowards to release the ball, the sleeve 21 is thrown forwards against the sleeve 21 and moves forwards with it to prevent the release of the locking ball which otherwise would occur.
