Definitions

  • the invention relates to a device for improving the hit pattern of a firearm, according to the preamble of claim 1.
  • the object which is to be achieved with the present invention is to create a device which prevents or at least dampens bending vibrations of the weapon barrel when firing.
  • Such tube vibration dampers are not known to the applicant.
  • the device for improving the hit pattern with which this object is achieved is characterized in that the device has the features in the characterizing part of claim 1.
  • the vibration damper preferably has an inertial body which is resiliently connected to the weapon barrel mouth.
  • This inertial body is, for example, ring-shaped and arranged coaxially to the barrel axis and in this position by a number Feathers, especially leaf springs.
  • the movement of this inertial body relative to the weapon barrel can be damped by a braking device with braking surfaces which are pressed against one another in a resilient manner.
  • the ring-shaped inertial body can be located between two disks rigidly attached to the pipe mouth and can consist of two rings which are pressed resiliently against the two disks.
  • the one ring of the inertial body can have a number of axial bores in which there are compression springs which press the two rings of the inertial body against the two disks rigidly attached to the pipe mouth.
  • the leaf springs can be attached at one end to the pipe mouth and supported at the other end on the inside of the annular inertial body.
  • Pins can be arranged between the two disks rigidly attached to the tube mouth and parallel to the barrel axis, on which the leaf springs are anchored at one end.
  • a weapon barrel 10 has an external thread 12 at its barrel mouth 11.
  • a muzzle brake 13 is screwed with its internal thread 14 onto the muzzle 11 of the weapon barrel 10.
  • This pipe muzzle brake 13 which is known per se, has inclined transverse bores 15, through which the propellant gases emerging from the muzzle 11 are deflected and thereby exert a braking effect on the return movement of the weapon barrel 10 after each shot in a known manner.
  • This pipe muzzle brake 13 has a shoulder 16 against which a first disc 17 abuts.
  • This first disc 17 has a sleeve 18 against which a second disc 19 bears at a distance from the first disc 17.
  • the pipe muzzle brake 13 has an external thread 20 at its rear end, onto which a threaded ring 21 is screwed, which presses the two disks 17 and 19 against the shoulder 16 mentioned and thereby presses the second disk 19 onto the sleeve 18.
  • a locking washer 22 prevents the threaded ring 21 from loosening.
  • compression springs 26 In the bores 24 there are compression springs 26 which are supported at one end on the bottom of the blind bores 24 and at the other end on the second ring 25.
  • These compression springs 26 endeavor to press the first ring 23 against the first disk 17 and the second ring 25 against the second disk 19.
  • a number of pins 27 are also inserted, which are supported at one end on the second disc 19.
  • a leaf spring 28 is attached to each of these pins 27, which are parallel to the weapon barrel axis.
  • Each of these leaf springs 28 surrounds a pin 27 on its half inner circumference and is supported on the adjacent pin 27.
  • One end of the leaf spring 28 lies against the inside of the first ring 23.
  • These leaf springs 28 are approximately the same width as the sleeve 18 and therefore also touch the second ring 25.
  • This ring 23 forms an inertial body.
  • the outer circumference of the ring 23 will be selected to be larger or smaller.
  • the outer circumferences 29, 29 ', 29' of the ring 23 are indicated by dash-dotted lines.
  • the smallest ring weighs 0.5 kg, the middle ring 1 kg and the largest ring 1.5 kg.
  • the vibration damper 30 essentially consists of the two rings 23, 25, which together form an inertial body 31, and the two disks 17 and 19, which together with the compression springs 26 form a braking device 32 for the inertial body 31.
  • the disks 17 and 19 have braking surfaces 33 and likewise the two rings 23 and 25 have braking surfaces 34, the compression springs 26 pressing the braking surfaces 34 of the rings 23 and 25 against the braking surfaces 33 of the disks 17 and 19.
