Abstract
A trip wire type mine has a plurality of trip wires, each trip wire being wound on a reel and ejected through an opening in a body of the mine by means of an ejection system. The ejection system may include a cutting device to cut a lid in a plate forming a plane wall of the hollow body of the mine, a movable system to displace the cutting device, and a pyrotechnic charge to drive the movable system. A projectile is attached to one end of each trip wire, and the charge is also used to eject the plurality of projectiles through the opening, thereby deploying the trip wires and placing the mine in an operational state.
Claims25
A trip-wire mine comprising:
- a hollow body accommodating a plurality of trip wires, wherein each trip wire is wound on a corresponding reel;
- and
- an automatic trip wire ejection system, the automatic ejection system comprising:
- a first device for freeing an opening in a wall of the hollow body of the mine,
- a plurality of projectiles, each projectile attached to a corresponding free end of one of the plurality of trip wires, and
- means to eject the plurality of projectiles through the opening in the body of the mine, the plurality of trip wires each simultaneously unreeling from the corresponding reels when the plurality of projectiles are ejected, wherein the first device comprises a cutting means mounted in the body of the mine adjacent the wall to cut a lid from said wall, and a second device for ejecting the lid.
A trip-wire mine having a hollow body, a plurality of trip wires and a plurality of projectiles located within said hollow body, each projectile attached to a corresponding free end of one of the plurality of trip wires, the hollow body comprising:
- two plane parallel faces, a first one of said two faces serving as a support on a ground;
- and
- a cutting means having a cutting plate abutting a second one of said two parallel faces, the cutting means integral with a movable system, said movable system comprising a piston that is telescopically displaceable with a pin along a first axis perpendicular to the cutting plate and passing through a center of the cutting plate, said cutting means cutting the second one of said two parallel faces.
A trip-wire mine having a hollow body, a plurality of trip wires and a plurality of projectiles located within said hollow body, each projectile attached to a corresponding free end of one of the plurality of trip wires, the hollow body comprising:
- two plane parallel faces, a first one of said two faces serving as a support on a ground;
- a cutting means having a cutting plate abutting a second one of said two parallel faces, the cutting means integral with a movable system, said movable system displacable along the first axis perpendicular to the cutting plate and passing through a center of the cutting plate, said cutting means cutting an opening in the second one of said two parallel faces;
- and an ejection system for ejecting each of the projectiles through the opening in the second one of said two parallel faces.
