Non-magnetic anti-personnel war mine

In a non-magnetic anti-personnel war mine, capable of being sown manually and mechanically, having:

• (i) a plastic body having an upper part and a lower part, and including a central hole and a lateral hole, the upper part being closed by a cap of elastic material to constitute a variable volume and pressure air chamber, the lower part being closed by a pan and constituting a cylindrical housing,
• (ii) a firing pin plunger safety and release device, a detonator, and an explosive charge, all contained in said cylindrical housing,
• (iii) a firing pin plunger in said central hole of the plastic body,
• (iv) a bag-shaped membrane in said lateral hole of the plastic body,
• the improvement that:
• (a) said firing pin plunger is guided within a guide socket,
• (b) said bag-shaped membrane is retained in said plastic body by a retaining ring which rests upon a first disc having an eccentrically drilled hole and a maze on its lower surface, said maze communicating with a centrally drilled hole in a second disc which ensures the sealing between the first disc and the bag-shaped membrane,
• (c) said firing pin plunger safety and release device is formed by a lever with two arms, in balance with respect to its centre of rotation, one said arm resting against said bag-shaped membrane, the other said arm being subjected to the force of a spring, the whole being arranged so that, when a predetermined pressure is applied to said cap, said pressure causes the compression of a spring acting upon said firing pin plunger and an increase in the air pressure within the air chamber such that the bag-shaped membrane inflates and causes rotation of the firing pin plunger safety and release device to allow the mine to explode.
