Definitions

  • the present invention relates to a land mine, more particularly an anti-tank mine, comprising an inner and an outer part which are guided to be capable of relative movement and in which the spring loaded striker of the fuze mechanism is actuated by the movement of the inner part relative to the outer part.
  • the striker In known land mines the striker is in general provided with a striker spring which on being released causes the striker to be propelled forward, so that the firing pin is caused to impinge upon the firing cap with sufficient speed thereby causing the mechanism to fire the mine. Hitherto this striker spring was assembled with pre-compression in the fuze mechanism of the mine and was maintained in this pre-compressed position by complicated locking devices until the fuze mechanism was actuated when a person or a vehicle passed over the mine, thereby releasing the striker which would set off the mine.
  • the striker spring is located without compression in the fuze mechanism-which is provided with a shear plate serving as a safety device-between the inner and the outer part of the mine; the said spring being compressed by the movement of the inner part of the mine relative to the outer part and is released by the actuating mechanism after a predetermined relative movement has been exceeded.
  • the fuze Due to the fact that the proposed striker spring is incorporated into the mine without compression, the fuze is not acted upon by any force 'until it is loaded by a vehicle passing across the mine, so that the striker cannot be propelled forward, ie the mine cannot be set off prematurely, even though it may be subjected to vibrations of some magnitude.
  • the shearing plate fitted to the fuze mechanism secures the striker spring against accidental compression; and by contrast this compression can only be applied to the spring after the shearing plate has been broken off e.g. by the vehicle passing over the mine. It is therefore possible to transport the new mine while the fuze is in position but without any additional safety pins which may have to be removed when the mine is laid, such transport being possible without any danger whatsoever.
  • FIG. 1 shows a land mine in longitudinal section incorporating the proposed fuze mechanism
  • FIG. 2 shows the compression and release mechanism for the striker spring on an enlarged scale in longitudinal section
  • FIG. 3 is a side elevation of the compression and release mechanism partly in section according to FIG. 2, and
  • FIG. 4 is a cross section taken on the line IV IV of FIG. 2 in the direction of the arrows through the compression and release mechanism.
  • the flexible pipe element 5 is provided with a pressure relief valve 6 so that the air can escape therefrom when a vehicle passes across the mine, thereby allowing the inner part to move downward.
  • the outer part of the mine is furnished with a carrying handle (not shown on the drawing) made of a flexible plastic.
  • the striker spring '11 is assembled into the fuze mechanism without pre-compression. It is only the movement of the inner part relative to the outer part which compresses this spring. T 0 prevent premature compression of the striker spring, a shearing plate .18 is provided as a safety device.
  • the shearing plate safety device is preferably located between the clamping bushing 9 and the fuze casing 8 in the fuze mechanism.
  • the safety sleeve 12 is supported by arms 19 with inwardly turned hooks 20 which in turn rest on the striker 10.
  • the clamping bushing 9 is provided with corresponding slots 21 so that it is not obstructed by these hooks or arms when it is being forced into the fuze casing.
  • On the outside these slots 21 are furnished with a step 22 which guides the arms 19 which are wider than the books 20. These steps are placed at an angle, forming a path 23 along which the arms 19 can slide. This causes the arms 19 to be splayed out, thereby increasingly compressing the striker spring 11.
  • the arms 19 are splayed out far enough to allow the hooks 20 to release the compressed striker spring in order to set oif the mine.
  • the safety sleeve and the arms are preferably made of an elastic plastic.
  • the method of operation of the proposed mine is as follows:
  • the air cushion inside the flexible pipe element is first compressed by the inner part 1 of the mine, which carries the applied load.
  • the inner part 1 first moves downward until the end face 24 of the clamping bushing 9 comes in contact with the supporting surface 25 of the outer part of the mine. If the load on the mine is sufficiently great to break oh the shear plate 18, the striker spring-which is supported at one end by the clamping bush, and at the other end by the striker and hence by the hooks 20 of the safety sleeve-is compressed by the movement of the clamping bushing 9 relative to the fuze casing 8 which now commences.
  • the proposed invention is not restricted to anti-tank mines.
  • the mine can be used with equal effectiveness also against light vehicles or against persons.
  • a detonator for a land mine particulanly for anti-tank mines comprising two parts of which one is an inner and the other an outer part and both parts being relatively movable one within the other, a fuze body in the inner part comprising a safety sleeve having integral depending arms each with an inwardly projecting claw, a firing pin secured in the sleeve, a clamping bushing having slots therein one for each arm and cam surfaces adjacent each slot, a striker in the clamping bushing and provided with a firing cap, a spring in the bushing and contacting against the striker without tension in its normal position, said clamping bushing when movable relative to the fuze body compressing the spring and the arms contacting the cam surfaces to force the firing pin into the firing cap after a predetermined relative movement of the two parts has been exceeded with the claws releasing the safety sleeve, the claws of the depending arms being directed at right angles to the axis of the detonator whereby in the position of rest of the
