Definitions

  • the present invention relates to a triggering device for signals to be triggered by trip wires or other wires or cords intended for remote triggering, in particular pyrotechnically ignited signals, or mechanical or electrical devices serving the same purpose.
  • a spring-triggered trigger device for such signals or alarm systems is known, in which a clamp arranged on a trigger lever is connected to the trigger wires and, after influencing the trigger or trip wire, triggers a firing pin via the trigger lever, which in turn triggers Primer ignites and with it a pyrotechnic signal.
  • the switching lever is connected to an upper switching cam, which acts in the tensioned state of the spring on a lower switching cam arranged on a firing pin, the upper switching cam being arranged in the form of a spherical shell in an upper indentation of the sleeve receiving a firing pin and the firing pin by all-round deflection of the release lever can be operated.
  • the sleeve has a diameter-widening recess, and at the lower end of the firing pin there is a ball cage and in this a recess into which the balls are pressed by the wall of the sleeve.
  • the spring is arranged between the cage and an upper retraction and at the upper end of the firing pin a locking pin with which the firing pin is tensioned.
  • the sleeve In its guide, the sleeve has longitudinal slots which, when it is tightened, are also displaced before contamination by an outer sleeve connected to the securing pin.
  • the bolt is tensioned against the spring force until the balls can escape into the recess and secure the bolt via a cylinder part that adjoins the recess.
  • the sleeve is not covered by the sleeve in the relaxed state and is therefore open to the entry of dirt particles, which in turn can impair the function.
  • the present invention has set itself the task of creating such a triggering device, which is simpler in construction and assembly, and which ensures greater functional reliability independent of contamination.
  • a triggering device for pyrotechnic signals that trip through trip wires or the like, optionally equipped with a primer, mechanical or electrical signals, consisting of a sleeve with a ball-shaped trigger plate on its head and a receiving device for the trip wire, and one with balls and one Trigger cam actuatable, a spring-loaded firing pin with locking pin striking mechanism, according to the invention in that the trigger cam is arranged on a cam holder against which a taper pin coaxially abuts with the cylinder adjacent to the cone, which is not connected to the cam holder, and wherein cam holder and taper pin in a head-side bore of the firing pin and in the region of the bore of the firing pin there are openings penetrating the wall, in which two or more balls are arranged, which in the tensioned state of the spring it bears against the cylindrical surface of the taper pin, and the firing pin is enclosed on the head side by a funnel collar with a cone tapering in the direction of release, on the inner
  • the firing pin can be axially guided in a simple manner by a cylindrical section adjoining the funnel part of the funnel collar and abutting the bolt.
  • the taper pin is pushed into the correspondingly long bore after the locking pin has been removed by the cam holder, and the balls can deflect inwards into the free space thus created, so that they do not touch the inner wall when the firing pin is moved down and thus jam is safely prevented.
  • the firing pin only needs to be pushed up against the previously inserted spring after the taper pin has been inserted so that the ball receptacle is exposed above the funnel collar and the balls can thus be inserted comfortably.
  • the spring is released, the balls are taken away from the openings and pressed radially against the cylindrical surface of the taper pin by the funnel so as to keep the firing pin in this prestressed spring state.
  • the locking pin is also pushed into the sleeve bores provided for this purpose, and the taper pin rests on the locking pin.
  • the triggering of the device corresponds to that of the above-mentioned prior art.
  • the sleeve is divided into a lower part and an upper part, which are screwed together, the upper part being cranked and the release plate rounded off at the top.
  • the sample part in turn carries the top of the funnel collar, which can be made by simply screwing in the upper edge of the bore receiving the cam holder and the taper pin, and has the outside thread for screwing the upper part and lower part of the sleeve, so that the parts to be assembled are assembled unhindered can be.
  • the firing pin has a lower stop, which can have any desired play on the sleeve wall, and between which and an insertion bores for the locking pin running below the locking pin or, respectively, transverse to the longitudinal axis of the device, has a recess between which the spring is held in tension or via which the spring moves the firing pin while relaxing.
  • the locking pin can be protected in a simple manner by a split pin or the like and an opposite diameter widening against unintentional pulling out.
  • a cord for remote security can be attached to the side opposite the cotter pin.
  • the trigger or trip wires are connected to the trigger device in a novel manner.
  • the trigger plate is arranged on a threaded bolt which carries an upper and a lower, meshing, preferably knurled, disc with its thread, between which an intermediate insert is inserted. After loosening a knurled nut, one or two wires crossing at any angle can be clamped between the intermediate insert and the upper and lower knurled nuts, the wires pressing into the intermediate insert, for which purpose they are made of flexible Material, such as plastic in particular, is formed. Knurling is used for better grasping, e.g. with gloves.
  • the device has a sleeve subdivided into a lower part 1 and an upper part 2, which is retracted on the head side.
  • the knurled disks 4 and 6 are screwed onto these and clamp the intermediate insert 5, which is preferably made of plastic, between them, the trip wires 23 being clamped between them.
  • the funnel collar 16 is molded onto the lower part of the sleeve. This jumps back relative to the outer diameter of the sleeve 1, 2 and carries the external thread which is used for screwing to the internal thread of the upper part.
  • the funnel of the funnel collar tapers inwards at the bottom.
  • the illustration shows the device in a tensioned, secured state.
  • a cylindrical section adjoins the funnel part of the funnel collar, which continues up to the stop 21 for the spring 15 and guides the firing pin 10 on the inside.
  • the latter has a coaxial bore 14 at the top.
  • the cam holder rests on the lower cone of the taper pin 13 from above, whose lower cone rests on the locking pin 11.
  • the firing pin 10 is broken in the area of the bore 14, and in this breakthrough are the balls 8, which are pressed radially inwards by the funnel of the funnel collar against the cylinder section of the cone pin and keep the firing pin 10 with the spring under tension.
  • the securing bolt 11 can be gripped by hand or pulled out via a cord 22. Then the device is armed. If the threaded bolt 7 is now deflected (trigger force 14-15 N), a deflection with a preferred dimension of 10 ° causing a plate deflection of 1.5 mm, the cone pin is pressed down to the same extent via the cam holder 12. The balls 8 reach the area of the cone and are pressed inwards by the funnel collar. The bore 14 is dimensioned such that the tapered pin can drop so far that the balls are completely free when moving downwards from the guide of the firing pin 10 following the funnel collar 16 downward.
  • the thread shown at the lower end of the lower sleeve part 1 is used for screwing onto a primer support 25 with primer 24, which is ignited by the trip wires when triggered.
