Definitions

  • the present invention relates to a trigger device for a firearm, with a tongue which is pivotally mounted in a hood housing against the force of a spring, wherein the spring forms a lever mounted in the trigger housing, one arm of the tongue attacks and the other arm a housing-fixed support is supported.
  • the object of the invention is to provide a trigger device for a firearm, which allows a structurally simple and rapid adjustment or adjustment of the trigger force during operation.
  • a trigger device of the aforementioned type which is characterized according to the invention in that the support is an eccentric rotatably mounted in the housing, on whose circumference the spring is supported.
  • the eccentric construction according to the invention can be accommodated in a small space and is therefore particularly suitable for the limited space available in modern firearms.
  • a preferred embodiment of the invention is characterized in that the eccentric is formed by a shaft rotatably mounted in the housing, which has at its periphery elevations, flats and / or indentations.
  • the shaft has a plurality of notches of different depth distributed over its circumference. By selecting the corresponding notch, the withdrawal force can thus be presented stepwise as it were.
  • the shaft has a plurality of notches of different depth distributed over its axial extent and can be moved in at least two mounting positions in the housing 1a. As a result, the number of possible switching stages for the withdrawal force adjustment can be further increased.
  • the shaft can be installed once in one and another time in a 180 ° position.

  • the shaft 10 has a plurality of indentations 11-14 of different depth distributed both over its circumference and over its axial extent. This makes it possible to bias the spring 4 differently depending on the rotational position of the shaft 10: FIG. 1 shows a first position in which the arm 9 enters a deep indentation 11, while FIG. 2 shows a more prestressed position of the spring 4 shows, in which the arm 9 is located in a less deep notch 12.

Abstract

La présente invention concerne un dispositif de détente (1) pour une arme à feu, comprenant une détente (3) qui est logée pivotante dans un boîtier de détente (2) à l'encontre de la force d'un ressort (4). Ce ressort (4) forme un levier monté dans le boîtier de détente (2), dont un bras (8) vient en prise sur la détente (3) et dont l'autre bras (9) s'appuie sur un support qui est fixé dans le boîtier et qui est constitué d'un excentrique (10) monté dans le boîtier (2) de manière à pouvoir subir une torsion et à la périphérie duquel s'appuie le ressort (4).
