Title: Detonator for training mine
Filed: 1984-02-02
Abstract: Detonator device for mines, particularly training mines, with a cylindrical housing (10) containing a striker pin (12) and an actuating lever (40) situated in succession to each other in the central axial direction, the striker pin (12) and the actuating lever (40) being embraced together, at least over part of their length, by a striker pin mount which is formed by clamp levers (14,14'), compressed in their lower zone by resilient means (16) acting radially inwardly and which has a recess (18) situated in a central axial position which includes a widened lower zone (18') tapering perpendicularly upwards and downwards, while the actuating lever (40) has a thickened attachment (41) adapted in shape to the widened zone (18') of the clamp levers (14,14') in which it is positioned, characterized by the fact that a) the clamp levers (14,14') in their upper - zone are immovably fixed in the axial direction and in the radially outward direction, by a cover (15) belonging to the cylindrical housing (10) and having a central axial boring and interacting with a step (13) in the housing (10). b) the widened upper zone (18') is followed at the top, by a second portion (18'') having an angular horizontal cross section and continuing in the form of a third cylindrical portion (18'') of greater diameter, and c) the thickened attachment (41) of the actuating lever is followed by a zone (44) of which the cross section is adapted in shape to the portion (18'') of angular horizontal section and belonging to the clamp lever, while the zone (44) continues at the top in the form of a cylindrical zone (43) of which the diameter is smaller than the diameter of the third cylindrical portion (18''') of the recess (18). -

(9pp) GBAB- GB2133515 B A detonator for a mine, the detonator comprising a cylindrical housing containing a spring urged striker pin to fire a detonator and an operating means, an end of the striker pin being embraced and retained against spring pressure by a mount also embracing the operating means, the striker and operating means being coaxially aligned within the housing, the mount being subdivided in at least one separating plane extending in the direction of the longitudinal axis and the operating means producing separation of the mount parts to release the pin. USAB- US4599946 A The ignition device for training mines includes a percussion bolt which is mechanically held in an inoperative position and is loaded by the action of a coil spring. When released, it is propelled axially towards a pyrophoric ignition charge to initiate an ignition chain. The device includes a cylindrical housing in which a percussion bolt and actuating lever are mounted one behind the other in axial alignment. - A number of cup-shaped members, pref. a pair, are mounted in the housing so as to surround at least a portion of the actuating lever and percussion bolt. Upon actuation of the lever by applying a force to it in a predetermined direction, the cups are spread apart against a biasing force to release the percussion bolt in the firing direction.
