Definitions

  • the invention relates to an ignition device for mines, in particular training mines with the features of the preamble of patent claim 1.
  • Such an ignition device is known from German Offenlegungsschrift 27 20 453. This known ignition device responds only to rotation or to tensile or compressive stress in the axial direction, but not to tensile or compressive stress in the radial direction. In addition, the ignition device is susceptible to failure and does not have sufficient safeguards against false tripping.
  • the object of the invention is therefore to provide an ignition device mentioned at the outset which additionally responds to radial or compressive or tensile loads and can therefore be used universally, and which is also simple and compact in design, so that false triggers are avoided and which still gives the possibility To provide fuses that enable the mine to be reused.
  • the subject of the invention is concerned with an ignition device which comprises a mechanically held firing pin which, for. B. interacts with a pyrotechnic charge, which in turn puts a practice charge arranged in the mine, which emits a smoke and / or a sound signal, into operation.
  • the ignition device 1 shows in longitudinal section an embodiment of the ignition device 1.
  • This consists of a mechanical part and, for example, a pyrotechnic part connected to it.
  • the mechanical part in turn comprises an essentially cylindrical housing 10 in which a firing pin 12, which is pretensioned by a compression spring 11, is detachably held.
  • the firing pin holder 14, 14 ' which is divided by at least one separating plane running in the longitudinal axis direction, is arranged on a shoulder 13 within the cylindrical housing 10.
  • a firing pin holder 14, 14 ' is described, which is divided in half by a single parting plane.
  • the firing pin holder can also be divided symmetrically in a different way and, for example, consist of three, four or even more parts with a little more effort.
  • FIG. 3 is a side view of one half of the half-split firing pin holder 14, 14 'is shown.
  • the upper area of the firing pin holder 14, 14 ' is held by a cover 15 having a central bore in such a way that movement in the axial direction or in the radial direction is not possible.
  • the lower regions of the firing pin holder 14, 14 ' are pressed against one another by resilient means acting in the radial direction.
  • spring means for example a ring spring
  • spring means can also be used to compress the firing pin holder 14, 14 '.
  • compression springs are used, which are supported on the inner wall of the cylindrical housing 10.
  • higher costs may have to be accepted will.
  • the firing pin holder 14, 14 ' has a central axial bore or recess 18, the shape of which is explained in more detail with reference to the side view in FIG. 3.
  • the bore or recess 18 in the lower region of the firing pin holder 14, 14 'initially has a relatively small diameter, which then opens into a bore with a larger diameter. This forms a shoulder 30 on which the firing pin 12 rests with its collar in the rest position.
  • This larger bore then opens into a rotationally symmetrical recess 18 ', which can be shaped like a hollow sphere or ellipsoid, for example.
  • a recess 18 "with an angular cross section and a cylindrical bore 18" 'of larger diameter then adjoin the recess 18'.
  • An actuating lever 40 protrudes into the bore or recess 18, which is only partially and then partially shown as an individual part in FIG. 4.
  • the operating lever 40 comprises several sections of different shape, which are described in more detail below.
  • the actuating lever 40 comprises an extension 41, which is adapted in shape to the recess 18 ', which can therefore be spherical or ellipsoidal.
  • the approach 41 has a blind hole 42, which comes to rest over the collar of the firing pin 12.
  • a hexagonal region 44 adjoins the spherical extension 41, which merges into a cylindrical region 43.
  • the cylindrical region 43 in turn ends, as can be seen from FIG. 1, in a disk 45 which lies in a plane running perpendicular to the longitudinal axis of the ignition device.
  • FIG. 1 In the assembled state (FIG.
  • the spherical extension 41 of the actuating lever 40 is arranged in the hollow spherical recess 18 ', while the angular region 44 of the actuating lever 40 is enclosed by the recess 18 "of the firing pin holder 14, 14' which has an angular cross section.
  • the recess 18 ′′ has a square cross section, while the angular region 44 of the actuating lever 40 is designed as an octagon.
  • the operation of the ignition device is described below.
  • the actuating lever 40 When the actuating lever 40 is subjected to pressure or tensile stress, that is to say a force is exerted in one of the two directions of the double arrow 100 (FIG. 1), the outer jacket of the spherical extension 41 of the actuating lever 40 presses against the inner wall of the hollow spherical recess 18 'and thereby presses through the O-ring resiliently held together halves of the firing pin holder 14.14 'in the lower region, with the result that the collar of the firing pin 12 initially seated on the shoulder 30 is released and the firing pin 12 under the force of the now relaxing compression spring 11 in the direction of the pyrotechnic Igniter 101 jumps forward.
  • the firing pin can also be released by a tilting movement of the actuating lever 40 from any direction, which is indicated schematically by the double arrow 102 in FIG. 1.
  • Tail light also leads to a torsion movement of the actuating lever 40, indicated by the double arrow 103 (FIG. 1), which is preferably triggered by a force acting tangentially on the plate 44, to release the firing pin 12, since the inside of the square recess 18 " arranged octagonal region 44 of the actuating lever 40 rotates about the longitudinal axis of the actuating lever 40 and thereby spreads the two halves of the firing pin holder 14, 14 '.
  • the universally usable ignition device consists of very few parts that can be manufactured very easily and inexpensively. This makes it possible to provide a very inexpensive ignition device.
  • the pyrotechnic igniters are not always necessary.
  • An electrical, optical or acoustic display of the mine function after triggering the ignition device can also be implemented in another way.
  • the first securing device comprises a split pin 51, which is inserted in a pull-out manner in a bore arranged transversely in the lower part of the housing 10 and thereby prevents the firing pin 12 from moving downward in the event of unforeseen release by the firing pin holder 14, 14 '.
  • This split pin 51 preferably serves as a transport lock; it is removed after assembly of the ignition device on site by means of the ring 51 'arranged on it.
  • the second fuse consists of a sleeve 50 concentrically surrounding the cylindrical housing 10 of the ignition device 1, which, as indicated by the arrow 57, is arranged to be displaceable in the longitudinal axial direction between two positions.
  • the sleeve 50 is in the lower position, in which the ignition device 1 is secured.
  • the securing is effected by two balls 52, which are mounted in bores of the cylindrical housing 10 and which are pressed through the inner wall of the sleeve 50 inside the cylindrical housing 10 against the parts 14, 14 'of the firing pin holder and thus prevent them from moving can spread radially and release the firing pin 12.
  • the sleeve 50 is shifted upwards in the direction of the double arrow 57 so that the recesses 53 in the inner wall of the sleeve 50 come to lie relative to the balls 52, which are no longer pressed radially inwards. In this way, the firing pin holders can act upon the actuating lever 40 stanchions 14, 14 'now move radially outwards and release the firing pin 12.
  • a once armed ignition device 1 can be secured again by safely pushing down the sleeve 50, so that the ignition device 1 is resumed and u. U. can be used multiple times. This is particularly useful for practice purposes, since costs can be saved.
  • the ignition device is encapsulated in moisture-proof manner by O-rings 55, 56 and a rubber bellows 54, so that the operability of the ignition device 1 is ensured even when exposed to moisture, for example in the case of a long storage period of laid mines in the field.
  • the O-ring 56 closes the bore that is released by pulling out the split pin 51 during the unlocking process.
  • FIG. 6 shows a perspective exploded view of a training mine system using the ignition device 1.
  • the training mine itself is identified by reference number 64.
  • the ignition device 1 is screwed onto a threaded connector 65 of the training mine 64.
  • different actuators can be plugged onto the actuating lever 40 of the ignition device 1, as indicated by arrow 60, namely either a pressure cap 61, a tilt rod 62 or a turnstile 63.
