Definitions

  • the invention relates to a pyrotechnic device for generating a launch signature and / or hit signature with charges that have a detonator.
  • Devices of this type can be used in combat exercises to simulate the effects of lightning, sound and smoke, such as occur when a projectile is fired and / or when the projectile hits the target. You get very realistic effects.
  • the object of the invention is to provide a device of the type mentioned at the outset, which is simple in construction, easy to use and enables the ignition of several charges in succession without major interruptions.
  • the solution according to the invention is that several charges are arranged in a holder and the striking mechanism can be moved relative to the charges.
  • the invention is not limited to arranging several charges in one holder.
  • the charges would be pulled through the device so that the device cannot be designed as a closed device.
  • Foreign objects get between the holder of the loads and the device and thus prevent the further transport of the loads.
  • the striking mechanism is not fixed and the holder with the charges is moved, but conversely the striking mechanism can be moved relative to the charges, these disadvantages do not occur since the device can be designed to be closed.
  • the device also takes up less space.
  • the device takes up essentially twice the length of the plate-shaped holder, since at the beginning the holder is located before the end and essentially behind the striking mechanism. If, however, it is provided according to the invention that the striking mechanism can be moved relative to the loads, the size of the device is determined by the size of the holder, since the striking mechanism has a smaller longitudinal extent than the holder if it has a larger number of loads.
  • the holder with the used charges does not need to be thrown away after the same has been ignited, but is reusable.
  • the charges are inserted into the holder and are not firmly clamped, there is in particular if the device e.g. is moved in a tank, the danger that when the firing pin strikes the charge will give way and therefore no more ignition. In order to avoid this, it is expediently provided that the charges are clamped or held in place under spring action.
  • the charges are arranged in a mounting plate and if a movable firing pin is arranged in a plate arranged parallel thereto for each charge and is spring-loaded in one direction away from the charge.
  • the firing pin can be aligned very precisely with the load, so that an exact ignition takes place.
  • the firing pin itself can then be operated with suitable devices.
  • the firing pin plate is provided with a locking plate for the firing pin that is displaceable relative to its plane, it can be prevented by simply moving this locking plate that a firing pin ignites a charge in an undesirable manner and at the wrong moment.
  • This locking plate could e.g. close the firing pin holes between the firing pin plate and the holding plate for the loads or engage in recesses in the firing pin protruding on the other side of the firing pin plate in order to lock it.
  • the mounting plate is pivotally attached to the device, the charges can be easily replaced on the one hand, while on the other hand no part can be lost.
  • the striking mechanism has a shaft which, when it is moved, is driven by a gear wheel rolling on a fixed rack and has projections, which clamp a movable mechanical element against a spring force and, when a certain angle is reached, suddenly release it in the direction of the firing pin plate and a firing pin located there.
  • the mechanical element has a pivotable angle plate and a plunger.
  • the force is exerted by a plate-shaped element on the firing pin. It is therefore not necessary for the mechanical element and the plunger to be exactly aligned with one another in the direction of travel of the striking mechanism, so that the mechanical elements e.g. can be arranged side by side for different charges, but can be ignited one after the other, i.e. with slightly different positions of the striking mechanism.
  • the striking mechanism has a spindle drive.
  • the drive can be a stepper motor or a motor whose speed and on-off times can be controlled so as to obtain the desired cadences of firings.
  • the device has a lamp which can be switched on when a charge is ignited, in particular with a predetermined time delay, the optical effect of the device can be increased, in particular during night exercises. With relatively small loads, it is not always possible to achieve an effect similar to that which occurs with a substantially larger actual load. If the smoke of the cargo is now illuminated with a lamp, the optical effect is increased.
  • the lamp can be a flash lamp and / or a halogen lamp.
  • the device is further characterized in that it is constructed in a modular manner. For example, several poses with loads can be arranged side by side.
  • Fig. 1 the principle of the device is shown. All parts can be arranged in a closed housing, which is shown in FIG. 5. This housing only has to be open at the top in the area of the charges 1, so that the effects of sound, smoke and bang can pass freely into the open.
  • the charges 1 have a lower edge flange 2 and a primer arranged at 3. They are used in a mounting plate 4 which are provided with corresponding bores 5 for this purpose, which expand at the lower end in order to accommodate the flange 2 here.
  • the firing pin 6 are arranged in a firing pin plate 7, which for manufacturing reasons consists of the plate-shaped elements 7a, 7b and 7c.
  • the firing pin 6 is acted upon by a compression spring 8 in such a way that it protrudes from the plate 7 at the bottom, ie on the side opposite the load 1. It is mounted in corresponding holes 9 in plate 7, which also hold O-rings 10.
  • a slidable Locking plate 11 which can be moved in the direction of the plate plane, so that edge areas of plate holes 12 can engage in a corresponding annular recess 13 of the firing pin 6, so that it is effectively prevented from moving upwards towards the load 1. This securing takes place by moving the plate 11 simultaneously for all loads 1.
  • a slide 14 is guided within the housing with guides, not shown, which can be moved in the direction of arrow 16 by rotating a spindle 15.
  • the spindle 15 is guided by a nut 17 on the carriage 14.
  • a gearwheel 18 rotatably attached to the slide 14 rolls in the direction of the arrow 19 on a toothed rack 20 arranged in the housing.
  • the gear 18 is in engagement with a gear 21 which is rigidly connected to a shaft 22 and rotates in the direction of the arrow 23.
  • Lever-like projections 24 are located on the shaft 22.
  • lever-like projections 24 press a plunger 25 to the right in FIG. 1 when the shaft 22 rotates in the direction of the arrow 23.
  • an angle plate 27, which is mounted on the carriage 14 at 28, is tensioned counter-clockwise against the action of a tension spring 29. If the lever 24 has pushed the plunger 25 far enough in and moves itself further, it slips off the head 35 of the plunger 25, which thus moves to the left under the action of the tension spring 29, the tensile force of which is transmitted via the angle plate 27.
  • the angle plate 27 moves suddenly under the action of the tension spring 29 in a clockwise direction and strikes against the firing pin 6, which is moved upwards and onto the Primer 3 hits and thus ignites the charge 1.
  • the plunger 25 is held against the angle lever by the compression spring 26 even when the lever 24 is not in contact with the head 35.
  • FIG. 1 Several of the arrangement shown in FIG. 1 can be arranged next to one another, the corresponding lever-like projections 24 also being angularly offset from one another on the axis, so that not all charges in a row are ignited simultaneously but in succession.
  • FIG. 2 shows a case in which the load 1 is pressed upwards by a holding element 31 with a spring-loaded ball.
  • a holding element 31 with a spring-loaded ball.
  • a separate plate 30 is provided which is provided with bores 32 through which the firing pin 6 can pass.
  • FIG. 5 schematically shows a perspective illustration of an embodiment, the embodiments actually produced normally having more charges 1 than shown. As can be seen, only the charges 1, a lamp, in particular a halogen lamp 33 and a drive shaft 34 for the spindle 15 protrude from the housing.
