A grenade firing mechanism 12 has a body 18 defining an internal chamber 32 in which a firing pin structure 40 is located. The firing pin structure is actuated by an inertia toggle 64 having a first end contained within the chamber and a second end region 72 which projects from the body. A safety lever 16 is releasably mounted to the second end region 72 of the inertia toggle in an operative position to prevent the inertia toggle moving to actuate the firing pin structure. A lever spring 104 is operative to eject the lever from the inertia toggle allow the firing pin structure to be actuated when the grenade is deployed. The lever 16 carries an abutment pin 120 which extends through the body to engage the firing pin structure 40 to inhibit the firing pin structure moving in a firing direction when the lever is in its operative position. The inertia toggle may have a convex abutment surface which engages the firing pin structure. The firing mechanism is particularly suited to a sound flash distraction grenade.

A safety fuze for use in military and commercial applications, includes a fuze body that is attached to a trigger mechanism, an energetic train contained within the fuze body, and a non-energetic fuze delay mixture that is formed in a rod form so that it can dropped inside the fuze body, without modification to the other components of the safety fuze. Preferably, the non-energetic fuze delay mixture is made of foamed celluloid.

The invention relates to a simulated fragmentation grenade that can be rearmed for reuse, comprising a fixed part attached to springs acting on plates that move between an inner position and an outer position, an axial mobile part passing through the fixed part, the axial mobile part being pushed upwards by a spring, and being axially extended in the upper portion by a rod that is rotatably actuated by a mechanism, the rod being attached to a control casing arranged on the outside such that it can move axially and rotationally on a central extension of the body of the grenade, the axial mobile part having retention means for retaining the plates in the inner position, for releasing that retention according to the movement of the axial mobile part.

Disclosed herein is a grenade with a plurality of independently detachable carpel segments each containing a charge and independently detonated from other carpel segments. The grenade may include a head section with a triggering mechanism, and a modular hollow core with a rod having an upward mechanical bias towards the head section, which may include a safety pin, lever, and pivot. When the pin is pulled, a lever can be released after timed delay, and the release of the lever allows the rod to advance upward, which triggers strike pins that strike a primer which ignites a propellent that ejects a carpel segment from the core. The propellent simultaneously ignites a fuse in the body of the carpel segment, and the fuse triggers a detonation of the main charge in the carpel. Timed delays on the fuse can be used to cause the carpel segments to detonate at different times.
