Definitions

  • the present invention relates to a handgun, with a frame and a longitudinally displaceably carried carriage, a trigger articulated to the frame, which is pivotable between a rest position and a firing position, to which trigger a trigger rod movable together with the same, with a front and a firing pin having a rear end which is movable between a rest position and a firing position, with a valve which is articulated on the frame and which can be pivoted about a pivot axis between a relaxed position and a tensioned position and a striking surface intended for striking the rear end of the firing pin and has a latching surface, on which tap an interrupter is articulated, and with a tap holder rotatably mounted in the frame about an axis of rotation, which can be moved between a tap blocking position and a tap release position, which tap holder has a blocking surface which is in the tap blocking lock llung abuts the locking surface of the cock in the relaxed position, and which is in the cock release position of the cock holder
  • the cock In known handguns, the cock is in the relaxed state in a position in which it constantly touches the rear end of the firing pin. This means that on the one hand there is a risk that a shot can be released if the handgun is dropped, if the tamper is manipulated unfortunately, or if the tap gets stuck on an obstacle (garment), and on the other hand the trigger must fire a considerable way and with to fire the weapon appropriate force, which process makes it difficult to shoot or hit a target.
  • the known handguns remain the cock after loading or after firing a respective shot in the cocked position, so that a second shot can easily be fired unintentionally, perhaps in a stressful situation.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, achieves the object of creating a handgun in which the cock in the relaxed position is blocked in a position in which its face is at a distance from the rear end of the firing pin and a Tensioning the cock for firing a shot with a smaller force combined with a smaller movement distance of the trigger takes place.
  • the advantages achieved by the invention are essentially to be seen in the fact that the tap is prevented from hitting the firing pin and consequently releasing a shot if the weapon is inadvertently dropped or manipulated incorrectly, so that the safety of the hand gun is significantly increased.
  • the cock also relaxes after the carriage has loaded, be it through loading or when firing a single shot, so that a second shot cannot be fired easily. After each load and after each shot, the tap moves into a relaxed position, in which it also does not rest on the ignition pin. This also eliminates the manual release lever, which is known to always cause a certain danger due to possible sticking to a garment in small arms.
  • FIG. 1 A gun is shown in simplified form in FIG. 1, in which the present invention is embodied.
  • this pistol is of a type that only fires with the double-action trigger system.
  • the carriage 2 On the frame 1, which is only indicated by dashed lines, the carriage 2 is arranged to be longitudinally displaceable in a known manner. A part of the barrel 23 and a loaded cartridge 24 are also shown.
  • the pistol has a trigger 3, which is articulated on the frame 1.
  • the trigger 3 is articulated on the trigger 3. This is shown in the top view in FIG. 6.
  • the trigger rod 4 is tensioned upwards by a leaf spring 25 in the illustration according to FIG. 1, which leaf spring 25 is connected to the frame by means of a screw bolt 26.
  • the firing pin 5 In the frame 1, the firing pin 5 is furthermore displaceable longitudinally.
  • the tap 6 has a striking surface 8 which is intended to strike the rear end of the ignition pin 5. From the figure it can be seen that the tap has no manual release lever.
  • the cock rod 27 is articulated on the cock 6, which is supported against the striking spring 28. 1 shows the interrupter 10, the tap holder 11 and the axis of rotation 12 of the tap holder 11. It can also be seen in FIG. 1 that the trigger rod 4 has a projection 21.
  • the interrupter 10 is pivoted about the axis 32 on the tap 6, which in turn is pivoted about the pivot axis 7 on the frame 1.
  • the interrupter 10, which extends over the rear crosspiece 33 of the trigger rod 4, has a downwardly projecting projection 30. This cooperates with a slope 31, which is formed in the frame 1.
  • the interrupter 10 further has a shoulder 19 which cooperates with a first recess 16 of the trigger rod.
  • the slope 15 of the ejector 14 is also indicated, which cooperates with the slope 18 of the trigger rod.
  • the slide 2 Due to the pressure created in the cartridge during the explosion, the slide 2 is stretched backwards, ie against the tap 6 (kickback) the cock 6, then moves forward again due to the feed spring (not shown) in order to load a further cartridge into the cartridge chamber and to release the cock 6, so that it can pivot back into the position shown in FIG. 3, in which it is intercepted by the tap holder 11.
  • This interception is made possible by the fact that the slide 2 acts with its control bevel 22 on the projection 21 of the trigger rod 4 during its recoil movement, so that it is briefly pivoted downward again in order to turn the (spring-preloaded) cock holder 11 back into that shown in the figure Allow position. Accordingly, the tap 6 is again in its relaxed, safe position.
