US 4,476,784 A · Anti-tank mine

Abstract

The present invention relates to a mine incorporating a pressure plate. Such a mine comprises, inter alia, a pressure plate, a pyrotechnic firing chain and an arming device. The pyrotechnic chain comprises a firing relay rotatably mobile in two substantially perpendicular directions to ensure alignment of the pyrotechnic chain by a double rotation of a support disc about a shaft and a mobile member about an axis. Maneuvering of an arming button ensures rotation of the mobile member; a clockwork timer device ensures rotation of the support disc. A further feature of the invention resides in the reversibility of arming, the opposite maneuver of the arming button ensuring that the mobile elements of the mine return to their intial position. In addition, an anti-blast device is incorporated in the pressure plate. The invention is applicable to anti-tank mines.

Dependent claims

An anti-tank mine having a casing, a pressure plate, a pyrotechnic firing and fire transmission chain constituted by a striker, a primer, a firing relay and a firing unit, a useful explosive charge, and an arming device, and comprising an improvement wherein the firing relay is mounted on a disc mobile in rotation about a shaft, said shaft being borne by a member itself mobile in rotation about an axis substantially perpendicular to the shaft of the mobile disc, and said relay being adapted to ensure alignment of the pyrotechnic chain by rotation of the disc about the shaft and rotation of the member about the axis, the rotation of the member ensuring alignment of the plane of the disc with the upstream part and the downstream part of the pyrotechnic chain, and the rotation of the disc ensuring alignment of the firing relay with these same elements of the chain.
