Definitions

  • This invention relates to a trigger mechanism for rifles, of the type comprising a trigger associated with a support.
  • the problem that lies at the heart of this invention is to devise a trigger mechanism for rifles which has structural and operating characteristics such as to overcome the drawbacks mentioned as regards the known state of the art.
  • a trigger mechanism of the type previously described characterised in that the trigger pivots in the said support, there being devices to adjust the angular position of the trigger in relation to the support.
  • the said adjustment devices are threaded.
  • a trigger mechanism for a rifle according to the invention is shown in a side, partly cutaway, cross-­sectional view.
  • 1 shows a trigger mechanism as a whole for a rifle, in particular for a so-­called shotgun.
  • the trigger mechanism 1 comprises a trigger 2 formed in a single piece and having an appendix 3 essentially semi-­circular projecting from a body 4 extending along a longitudinal axis of the rifle, or firing axis, shown by X; body 2 has a muzzle portion 4a and an opposing breech portion 4b.
  • Trigger 2 pivots in a lever support 5, fitted with a lever 6 designed to operate in a known manner a release mechanism which is totally conventional and therefore not shown.
  • trigger 2 pivots in support 5 at an intermediate portion of body 4 and the relative pivot axis Y is perpendicular to firing axis X.
  • Trigger mechanism 1 also comprises threaded adjustment devices 7 to adjust the angular position of trigger 2 in relation to support 5.
  • threaded adjustment devices 7 comprise a threaded through hole 8, formed in the breech portion 4b of body 4 and facing a ledge 9 formed in support 5, and a threaded dowel 10 engaged in the said hole 8 and having a head 10a facing essentially towards appendix 3, and an opposing end 10b protruding beyond hole 8 and facing towards ledge 9.
  • the trigger mechanism With the trigger mechanism according to the present invention it is possible to make a continuous adjustment of the position of the trigger; this adjustment is also very quick and effective.
  • the fact that the head of the threaded dowel is immediately accessible, without the need for any component of the trigger mechanism to be removed is a particular advantage.
  • An additional advantage offered by the trigger mechanism according to the invention is that of a simple structure completely free of clearances between the trigger and support thanks to the above-mentioned spring devices.
