Definitions

  • the invention relates to a mine, in particular an anti-tank installation mine with a device for re-securing the mine and a rotor which can be moved from the safeguard to the arming mechanism and which can be mechanically fixed in the safeguard, and with a marker charge.
  • a mine of the type mentioned is known from DE-AS 24 23 912.
  • a device for re-securing is provided with a switching element which can be moved from the safe to the arming and from the arming to the re-securing position under the influence of a locking mechanism, to which a device indicating the re-securing is assigned.
  • the marker charge is ignited in the re-seizure that has been taken, and the explosive charge cap is also destroyed at the same time.
  • a disadvantage of such a mine is that not only the marker charge after re-securing and possibly a new battery must be used, but also that the entire re-securing device must be removed, disassembled and re-used if this mine is to be reused is provided.
  • the device for re-securing the mine is a mechanical control device which, on the one hand, rotates the rotor into the armed position on receipt of a first signal from a connected electronic system and, on the other hand, at Receiving a second signal from the electronics returns the mine safety device to the de-energized state of restoration; the electronics then trigger the marker charge to indicate the mine’s recovery status.
  • the mine in focus can be ignited by an electrical signal from electronics associated with the mine. If an ignition is not to take place, which is possible both after the set time has elapsed and before the set time has elapsed, a second signal from said electronics gives the mine safety device the command to return to the deenergized initial state.
  • the present invention thus discloses a security device for an anti-tank installation mine, which can be reset and thus secured again and in this way makes the mine usable as often as desired.
  • control device can be formed from a lockable control shaft, on which two coaxially arranged control wheels are arranged, which are connected to one another by a torsion spring and of which one control wheel is drive-connected to the safety device of the mine and rotatably mounted on the control shaft, while the other steering wheel is drive-connected to the rotor via an intermediate wheel, which can be fixed by a force element which is operatively connected to the electronics of the mine for the reception to trigger the active charge.
  • an incidence disk which has a recess after 180 ° in its circumference, in which a spring-loaded core of a radially arranged to the control shaft solenoid engages, and that the steering wheel, which is drive-connected to the safety device of the mine, one has at least 180 ° ring recess, in which a pin protrudes axially to limit rotation.
  • the securing device can be formed from the control wheel connected to the control shaft with an inserted torsion spring and the barrel connected to the steering wheel with an inserted torsion spring and coaxially arranged spring core and the gear mechanism connected to the barrel via a clutch wheel.
  • the spring core can be clamped by a spiral shaft with the help of an elevator wheel and can be locked in a tensioned state by a lock, the lock being able to be released on the one hand by a rotary lever on the surface of the mine and on the other hand being unlockable by the locking movement of the core of the lifting magnet, the rotary lever being simultaneous is in pressure connection with the spiral shaft and furthermore actuates a switch for starting the balance of the gear mechanism.
  • the rotary lever can lock the battery compartment cover when it is turned into focus and, when the axial pressure is exerted at the same time, set the spiral shaft in rotation, which directs the force absorbed into a clamping disk arranged approximately at the lower end of the spiral shaft, which has tangential incisions on the outer circumference, in which pinch rollers are supported, which rest against the inner wall of an elevator wheel that is connected to the spring core, whereby the spring core, locked by turning the rotary lever into focus position by a mechanical lock in the energized state, tensions the torsion spring of the barrel, which on the one hand tensions the gear via the clutch wheel drives and, on the other hand, is gear-connected at the same time to the one control wheel of the control shaft, which is connected via a torsion spring to a second control wheel of the control shaft, which in turn engages with the rotor via an intermediate wheel stands, which is held in the securing by a force element, and in that the control shaft is fixed in wait position by the radi
  • Another advantage of this laying lead is the laying reliability when focusing, which is made possible by the attached gear mechanism.
  • the refill 44 shown in the housing 29 forms an essentially circular body with a surface 30 into which the battery compartment cover 27 is embedded.
  • a rotary lever 1 can be locked in the securing of the lead 44 by a tab 28 on the lead surface and is in focus against a stop 31 on the underside of the cover or on the housing cover.
  • a nose 46 on the rotary lever 1 lies directly above the battery compartment cover 27, which cannot be opened in this position.
  • the axis of rotation of the rotary lever 1 can be seen at 47 in FIG. 1.
  • the start of the unlocking time and thus also the start of the possible functional sequences begins with the removal of the tab 28 from the rotary lever 1.
  • the elevator device By pressing the rotary lever up to a mechanical stop, the elevator device according to FIGS. 3 and 4 is actuated in such a way that the force is conducted into the clamping disc 4 via the spiral shaft 2 and the lower friction disc 3 and from there into the clamping rollers 5 .
  • the pinch rollers 5 lie against the inner wall 43 of the elevator wheel 6 and take this elevator wheel with them during the rotational movement as long as the force is supplied by the spiral shaft 2 via the axial pressure.
  • the elevator wheel 6 is in drive connection with the spring core 7, which in turn is connected to the barrel 10 and the torsion spring 9 arranged in the barrel 10.
  • the energy applied remains stored in the barrel 10 until the rotary lever 1 is turned to the arming position.
  • a mechanical lock 11 is triggered, which locks the spring core 7 in the energized state.
  • a toggle switch 12 is actuated, which causes the balance 13 of the gear mechanism 8 to start up.
  • the balance 13 swings out of the zero position.
  • the mechanical gear mechanism 8 is driven by the torsion spring 9 of the barrel 10 and expires within a predetermined time, which corresponds to a safety for people and facilities when the mine 44 is moved and the activation in focus.
  • the torsion spring 9 simultaneously pulls on the control wheel 17 the previously energetic torsion spring 15 of the control shaft 16.
  • the rotational movement of the control shaft 16 is limited by an axial pin 41 which engages in a 180 ° annular recess 21 in the control wheel 17.
  • the control shaft 16 has carried out the rotation of 180 ° in about 10 minutes.
  • the sprung core 33 of the solenoid 18 can now fall into a recess 34 in the cover plate 19 mounted on the control shaft 16 and thus lock the control shaft 16.
  • the spring core lock 11 is unlocked via a rigid lever connection 35.
  • the residual energy remaining in the barrel 10 can be dissipated via the spring core 11 in the direction of the elevator wheel 6 until the torsion spring 9 of the barrel 10 is without energy.
  • the spring lock 11 remains unlocked. It is held in the rearmost position by the locking spring 20 (leaf spring) and only released again by the control cam 36 of the switching socket 37.
  • Mine 44 is now in wait. During this time it is not possible to make the mine 44 unusable by turning back the rotary lever 1 or by removing the battery by removing the battery compartment cover 27.
  • the applied voltage is constantly checked during the action time of the mine 44. If a sudden drop in voltage is registered, for example by turning the rotary lever 1 into the safety device, the trigger signal for the active charge is automatically given and the mine 44 ignites.
  • the signal for triggering the active charge causes the force element 23 to be ignited, as a result of which the rotor 14 is released from its fixed position.
  • the energy of the torsion spring 15 now causes, via the steering wheel 24, which is arranged coaxially to the steering wheel 17 on the control shaft 16, a rotation of the drive-connected intermediate wheel 25 and thus finally the rotation of the in turn drive-connected rotor 14 into the armed position to ignite the mine 44.
  • the signal for resetting the core 33 of the lifting magnet 18 from the electronics 38 causes the torsion spring 15 to relax via the control wheel 17, the barrel 10 with the spring core 7 and the clutch wheel 26.
  • the safety device is again in the de-energized starting position and secured. After this re-securing, the marker charge is ignited to indicate the restored state of the mine 44.
  • the refill 44 can immediately be made ready for use again and relocated. This process can be repeated any number of times.
  • the signal from the electronics 38 for the recovery of the mine 44 takes place either after the time specified in the electronics has elapsed or by a signal from a remote control or the like sent from the outside.
  • a line 48 leads from the electronics 38 to a battery, not shown here, which ensures the energy supply.
  • the line 49 connects the electronics 38 to the force elements 23 and the further line 50 is a connection between the electronics 38 and the active charge.
  • the electronics 38 is connected to the solenoid 18 through line 51, to a switch 56 through line 52, to the marker charge through line 53, to the clearing charge (not shown) through line 54, and finally to a voltage monitor (not through line 55.
  • a common ground point which is known per se and is also not shown, is located on the safety device.
