Definitions

  • the present invention relates to the field of handguns, both compressed air and handguns with ammunition, and in particular relates to a device for triggering the firing pin body, which, depending on the application, opens the compressed air valve or strikes the primer around the shot due to the actuation of a trigger to deliver.
  • the firing pin body mentioned which is normally pressed by one or more springs, is retained in a preparation-for-shot position by a locking tooth of a pivotable element which is held in position by another element which is mechanically connected to the trigger and after supports the principle of the inclined plane on said pivotable element and thereby prevents it from rotating and releasing the firing pin body, which is under the action of an elastic system connected to it.
  • the lock In order to trigger the shot, the lock must be released through the inclined plane by moving levers connected to the trigger.
  • a too long expiry of the triggering process which is proportional to the length of the grinding track of about 0.2 mm between the surfaces.
  • a further limitation which the known devices show is that during the entire phase of pulling the inclined plane the trigger cock must overcome a resistance which is the sum of the forces of the retaining and return springs of the various elements and the resistance due to the wear of the inclined plane. When the locking tooth is released, this resistance disappears all of a sudden, and the shooter's finger exerts further forces on the weapon handle due to the inertia, which again impair the accuracy of the aiming.
  • the present invention relates to a mechanism which is actuated by the trigger of a handgun, in order to release the firing pin body, and to fire the shot, characterized by the characteristics specified in the characterizing part of claim 1.
  • Fig. 1 it is shown how in the embodiment shown a firing pin body 3 is pressed by its compression spring 8 against a locking tooth 5 of a first element 5, which is arranged pivotably about a pivot point A, and to which the pressure of a restraint and Return spring 6 acts.
  • the torque that this spring gives him counteracts that which the firing pin body 3 gives him, but is less than that; said first element 5 would rotate in a clockwise direction and would detach itself from the firing pin body if it did not touch a second rotating element 4, which is rotatably mounted about the pivot point B, in a contact point T, in which point of contact the two rotating elements each one perpendicular to the profiles exert standing force.
  • This point of contact T does not lie on the connecting straight line r, which connects the two pivot points A and B, but far enough away from it that rotation in the described direction of rotation of the two elements 4 and 5 remains blocked relative to one another, since an overlap of their profiles would result.
  • the profiles of the two elements 4 and 5 mentioned are designed in such a way that the envelope curve C, which all points of the profile of the element 5 directed towards the other element 4, including the contact point T when rotating about the pivot point A. describe, outside the profile of the named element 4 lies.
  • the mechanism described can also be used to adjust the path of the trigger tap 2 to the pressure point grasp, since this path is independent of any mechanical connections to the rest of the mechanism.
  • FIG. 2 Another embodiment of the device according to the invention is shown in FIG. 2:
  • the firing pin body 3 is retained by a locking tooth 17a which is seated on a locking piece 17 which is coupled via a pivotable joint to a rotary lever 18 provided with a return spring 16.
  • the spring 14 connected to the element 14 is partially compressed when the mechanism 21 is in static equilibrium.
  • the element 14 can also freely rotate clockwise around the pivot point D, since all points of its profile in the area of the contact point Q during rotation describe an enveloping circle t which is outside the profile of the other element 15.
  • the element 14 rotates in such a way that, when thrust by a force proportional to the energy given off by the spring itself, it strikes the previously described rotary lever 18, causing a clockwise rotation of the mentioned, associated locking piece 17, and therefore also the release the locking of the firing pin body 3 can be caused by the locking tooth 17a.
  • the firing pin body can then slide freely under its spring 8 on its functional path.
  • the device according to the invention can be implemented in a wide variety of ways, wherein different kinematic chains and / or elements with different contours and profiles can be used.
