Definitions

  • top refers to a weapon, which is in normal use position and whose soul axis (running center axis) runs horizontally; "Front” is in the weft direction.
  • a trigger device in the simplest case consists of an impact piece with Striking spring, which is held in a tensioned state by a rest is that can be solved by a deduction.
  • Self-loading weapons set up for single-fire delivery have a so-called interrupter, which is the connection between the deduction and the Interrupts the hammer or cock immediately after the shot, if the trigger from the previous shot is still actuated but the weapon is ready to fire again.
  • Fume cupboards should also have as few parts as possible have as well as reliable and durable his. In addition, fume cupboards are said to be lacking Care, pollution and weathering insensitive, as light as possible and the individual parts as possible be easy and economical to manufacture.
  • a trigger device for a rapid-fire rifle which can be switched between continuous fire and single fire and equipped with a fuse, functional and therefore structurally so complex that a Specialist, who is well known that the construction of a such fume cupboard takes weeks, knows that even a small change to an unexpected component and causes undesirable interactions.
  • the known trigger device of the rifle mentioned at the beginning G3 is what functional safety and insensitivity to pollution concerned, able to meet all requirements. It is also, compared to other known fume cupboards, relatively easy to build and because they are only wire springs used, in the production also relatively inexpensive.
  • the trigger In the case of a single fire, the trigger is in turn pivoted by moving the trigger.
  • the trigger lever gives the second locking studs free, so that the tap knocks off.
  • the trigger At the Subsequent shot will trigger the trigger by springs Pressed in front, comes from his back with him lifting engaging nose free and can therefore by a other spring can be pivoted again in the opposite direction, so that he was back with the second counter tunnel Can catch catch tunnels.
  • the tap turns during the locking movement cocked and in this position from the jack held until this is pivoted through the closure and thus releasing the first locking gallery. Now the tap falls with its second locking gallery in the counter gallery mentioned above and pushes the trigger against the Force a spring backwards.
  • the trigger In order to be able to fire continuously, the trigger must be pivoted further be around the trigger with its counter lug from the range of movement of the second locking stud of the tap swing out. In this case it is natural irrelevant which position the trigger lever is in because it is no longer able to intervene in the tap. This is only held by the handle and it strikes therefore, as soon as the shutter is closed and at the same time the jack pivots.
  • the shot breaks in single and continuous fire in the same
  • the trigger is in the angular position, but must then be used for continuous fire the trigger can be pivoted further to prevent that the trigger lever and the cock engage in each other.
  • the gunner is irritated by the fact that the rifle has single fire shoots even though continuous fire was selected.
  • the invention is based on this prior art the task is based on the known trigger device to develop such a way that it is even more reliable becomes.
  • the trigger path by which the trigger is pivoted must always be the same for single and continuous fire his.
  • the weight should be reduced as much as possible, the manufacture Simplified as possible and the cost as possible be minimized.
  • the Switching device has an engagement element which in Engagement with the trigger can be brought and its forward movement prevented.
  • the trigger is not in constant fire, as in the known trigger device, by its pivoting movement and disengaged the trigger from the tap, but the engagement element prevents the trigger moved forward as it would need to be as Breakers to be effective.
  • the position of the trigger is according to the invention the same as for single fires.
  • this is not a completely new trigger construction chosen but the well known and maintained through an additional engagement element in their actual Function hindered. But this leads surprisingly not to the inability to function as one would have expected can, but excluding the above Mistakes even have an improved effect.
  • the spring device acting on the trigger lever known trigger device is formed from two springs, of which the one the trigger with the counter lug to Hahn pivots and the other pulls the trigger forward charged. This arrangement is necessarily based on long swivel path that the trigger lever puts together has to cover with the deduction; also in need of firing a shot in continuous fire position another Swing the trigger not to hinder.
  • the pivot path of the trigger is considerably shortened so that the spring device now can only be formed by a single compression spring (Claim 2) between a point of deduction below its pivot axis and a point on the trigger is effective before this pivot axis.
  • a single compression spring (Claim 2) between a point of deduction below its pivot axis and a point on the trigger is effective before this pivot axis.
  • This compression spring is not only a structural simplification, it is also less exposed than the known one Spring device so that the risk of pollution is significantly reduced, which leads to a malfunction could lead.
  • the compression spring presses the trigger to the front and with the counter tunnel upwards.
  • the engagement element can be designed as a pivot lever, for example be the one with a cam projection in the trigger intervenes. Because the engaging element is not the trigger somehow needs to move, but at tense and weapon set to single fire only in its Movement trajectory is only one for its operation very small force sufficient.
  • the engaging element is preferably a slide trained because a slide is easiest in the Fume hood can be attached without their operation to disturb (claim 3).
  • the slide can be designed as a cross slide with a push button on each of its ends, depending on your choice the type of fire (single or continuous fire) on one or protrudes other long side of the handle.
  • This roller preferably has on both sides of the handle an operating lever and carries cam projections that can also be formed negatively as depressions and control the security function. At least one The cam projection can also engage in the slide mentioned, then preferably in the longitudinal direction of the weapon is movable. The cam projection can then Hold the slide in the case of a continuous firing position of the roller.
  • the slider can only be on the cam from below Act on the roller, thereby other functional elements of the Trigger device not to be affected.
  • Such a plastic handle can not only special be formed inexpensively, but is particularly light and does not rust. Because such a plastic is limited is stretchable, the axes and shafts can be in their dimensions drilled holes with little effort are pushed in, but are rebounded by the Material held tight and sealed there. Doing so not, as with fitting bores in steel parts, tight tolerances be respected. Such bores also deteriorate Do not push and push a shaft or axis several times out.
  • This handle according to the invention is for the invention Extraction device particularly suitable because with this the forces are low by the axes or shafts be transferred to the plastic material of the handle.
  • the impact spring device which acts on the tap, not designed as a helical compression spring supported on an abutment on the tap and box, such as at the generic deduction facility.
  • the impact spring device is rather of two wire leg springs formed, each of which has a clothespin spring with two Thighs and a helical section resembling that sits on a stub shaft stub, which is one-story with the plastic tap and the tap axis is enforced. Support the legs facing each other each on a lateral projection or training of the rooster. The free legs on each outside are based on projections or corresponding training inside the plastic handle. Any of these Training is only with half the total spring force charged. This burden can also be caused by appropriate choice of leg length reduced to a value be of the fatigue strength of the plastic material Training does not exceed.
  • the two legs facing each other can also by a crossbar be connected to each other, against the Tap is present.
  • a trigger device 5 sits in the box.
