Definitions

  • the present invention relates to a means for a trigger mechanism for weapons, in particular firearms with a striker mechanism, which is tripped mechanically.
  • Mechanisms of this kind consist of a trigger and a spring-actuated striker element or hammer and at least one interjacent element for the functional connection of the trigger with the striker element or the hammer, wherein the trigger, the striker element or the hammer and the interjacent elements together form a series connection pre-loaded under spring bias of organs capable of being actuacted in sequence, said series connection being sc arranged as to be kept pre-loaded under spring bias by means of a catch or hooking organ capable of suddenly releasing the pre-loaded series connection so as to trip the striker element, and wherein the catch organ constitutes a functional connection between two consecutive organs from amongst the aforementioned organs in the series connection.
  • One of the disadvantages of the conventional mechanism is that the common engagement surfaces which the trigger forms with the trigger bar (or hammer) must be machined to extremely high standards of fineness and must be absolutely perpendicular to each other (requiring individual fitting).
  • the surface pressure When the trigger slides out of engagement with the trigger bar, the surface pressure will be increased in proportion to the decreasing engagement surface in such a way as to accentuate any irregularity, resulting in "rough” pressure, which is particularly inconvenient in competition weapons.
  • the result of this unsatisfactory surface pressure/friction is in most cases for progressive wear to take place to such an extent that the pressure feels increasingly "rough” and no longer provides the same resistance in the trigger. Pieces may even break away from the engagement surfaces in the worst cases, often resulting in shots being fired accidentally.
  • the object of the present invention is, therefore, to propose a means of the kind indicated by way of introduction which will provide smoother pressure and reduced frictional resistance in the trigger. This purpose is achieved by having provided the means in accordance with the invention with the characteristics indicated in Claim 1.
  • Figure 1 shows in schematic form a cross section of the means in accordance with a preferred embodiment of the invention.
  • Figure 2 shows a view from the front of a trigger bar in the means in accordance with the invention.
  • Figure 3 shows a longitudinal section on an enlarged scale of a roller in the means in accordance with the invention.
  • Figure 4 shows a variant of the embodie- ment illustrated in Figure 1.
  • Figure 1 shows in schematic form a part of a mechanism for a hand firearm (not shown), for example a rifle.
  • the mechanism generally includes a series connection pre-loaded under spring bias consisting of a trigger 1, a trigger link 2, a trigger bar 3 and a striker mechanism shown here only in part in the form of a striker element 4.
  • the trigger link 2 and the trigger bar 3 in this case constitute a first and a second element which can be caused to slide out of engagement with each other by actuation of the trigger 1.
  • the trigger 1 which is pivotally mounted about a stationary shaft 5, is maintained in the inactive position shown in Figure 1 by means of a spring 6.
  • the trigger 1 exhibits an arm 7 which, together with a heel 8, is intended on firing to actuate the trigger link 2.
  • the trigger link 2 which is also pivotally mounted about the shaft 5, is retained by means of a spring 9 under pressure against a catch or hooking organ in the form of a roller 10, which is pivotally mounted about a shaft 11 in the trigger bar 3.
  • the trigger bar 3 which is mounted about a stationary shaft 12, is held by means of a spring 13 under tension against the striker element 4, which in turn presses against the trigger bar 3 with a spring 14, the spring bias of which is considerably greater than that of the spring 13.
  • the roller 10 is in contact via its outer surface 10a with two bearing surfaces 15 and 16 in an angle shelf 17 formed in the trigger link 2.
  • the roller 10 exhibits an internal, curved contact surface 10b with the shaft 11; see Figure 3. This enables the roller 10 to adjust itself to any angle and to make contact at all times via its outer surface 10a with uniform pressure over its points of contact with the bearing surfaces in the angle shelf 17, even if the latter is not parallel with the bearing shaft of the roller.
  • the trigger 1 will force the heel 8 in the direction of the arrow A towards the trigger link 2, which will be caused to rotate against the effect of the spring 9 out of engagement with the engagement roller 10 of the trigger bar 3, when the trigger link 2 will move in the direction of the arrow B.
  • the roller 10 will rotate about its shaft 11, and will roll over the bearing surface 15 in the trigger link 2. Since the spring bias of the spring 14 is considerably greater than that of the spring 13, the trigger bar 3 will rotate quickly in the direction of the arrow C and will cause a sudden release of the striker element 4 in the direction of the arrow D.
  • a further advantage of the invention is that individual fitting is no longer necessary, since all the component parts of the mechanism can be installed with or replaced by any others.
  • the rolling engagement also means that no noticeable wear will arise in the respective parts.
  • FIG. 4 A variant of the embodiment in accordance with Figure 1 is shown in Figure 4.
  • the means in accordance with Figure 4 harmonizes with that shown in Figure 1, with the exception that the trigger link 2 is hooked directly by a striker element or hammer 4', i.e. without any interjacent connection in the form of a trigger bar.
  • the striker element 4' is mounted about a shaft 18, and is pivotally mounted in the direction of the arrow D', similar to the movement D of the striker element 4 in Figure 1.
  • the roller 10 is mounted in the striker element 4' in an entirely similar fashion to that in which the roller 10 is mounted in the trigger bar 4 in accordance with Figures 1-3.
  • roller in the two embodiments shown is so arranged as to interact with a trigger link 2, it is obvious within the context of the invention that it is possible for the engagement to be effected instead directly with the trigger 1, if the latter is given a form suitable for the purpose.
  • roller is mounted in the trigger bar of the striker element, but can, of course, as an alternative, be mounted in the trigger link (or in the trigger).
