Abstract

The invention relates to a trigger system (1) of a firearm, with a trigger lever (2) and a trigger tongue connected thereto (3), wherein the trigger lever (2) in a trigger housing (4) is pivotally mounted, wherein the trigger lever (2 ) is mounted pivotably about a trigger lever pivot axis (5), wherein a pawl (7) pivotable about a pawl rotation axis (6) is provided which by contact with the trigger lever (2) and pivoting about the pawl rotation axis (6) pivoted about the shot of the firearm mechanically trigger, wherein the bearing of the pawl rotation axis (6) and / or the bearing of the trigger lever pivot axis (5) and / or another bearing a rotation axis in or on the trigger housing (4) arranged magnet (9) is assigned, which forces on the bearing axis (10) of the bearing exerts, so that this is pulled without play against the bearing guide (11) of the bearing axis (10).

Description

The invention relates to a trigger system of a firearm, with a trigger and an associated trigger with this trigger, wherein the trigger lever is pivotally mounted in a trigger housing.

Such trigger systems are used in particular in sports in high-precision firearms, for example in national and international competitions with air rifle or small-caliber rifle. The shooters are perfectly familiar with their weapon and their operation and can be unpleasant especially when pulling the trigger triggering and triggering the shot bearing clearance, the moving parts in the trigger system or other inaccuracies, as this can adversely affect the precision during the firing.

From the DE 10 2004 063 967 B4 For example, there is known a handgun for sports shooting having a take-off unit having spring means for a preferential force and a pressure point force, a switchable spring means being provided for gradually increasing the pull-off force.

From the DE 29 26 559 A1 an electrical trigger device for firearms is known in which a pivotally mounted trigger element cooperates with a spring-loaded preferred cam and a spring-loaded pressure point cam.

From the DE 699 13 175 T2 a gun is known, in which a pivotable locking lever cooperates at its end with a magnet which acts against a counter-force device in the form of a spring.

From the DE 20 2013 005 117 U1 a trigger device is known in which a pivotally mounted trigger is moved by an electromagnet.

The object of the invention is to provide an improved trigger system of a firearm, in which a bearing clearance is reduced.

This object is achieved by a trigger system of a firearm according to the features of claim 1.

According to the invention, a trigger system of a firearm, with a trigger and an associated trigger finger, wherein the trigger lever is pivotally mounted in a trigger housing, wherein the trigger lever is pivotally mounted about a Abzugshebeldrehachse, wherein a pivotable about a pawl pivot pawl is provided which by contact with the trigger lever and pivoting thereof about the pawl rotation axis pivoted about the firing of the firearm mechanically trigger provided, wherein the bearing of the pawl rotation axis and / or the bearing of the trigger lever pivot axis and / or another bearing a rotation axis of a part of the trigger system arranged in or on the trigger housing magnet is assigned, which exerts forces on the bearing axis of the bearing, so that this is drawn without play against the bearing guide of the bearing axis. As a result, the bearing clearance is thereby reduced or completely avoided in a particularly effective manner, that the pawl rotation axis is pulled by the magnetic force completely on one side of the bore. Since the pawl rotation axis thereby always defined at the same location, the shooter is always guaranteed the same deduction.

An advantageous embodiment of the invention provides that the magnet on the trigger housing with respect to its distance from the bearing axis is supported adjustable. As a result, the magnetic force acting on the pawl rotation axis can be adjusted very effectively.

Following the magnet is formed by a grub screw or is attached to a grub screw, wherein the grub screw is screwed into a thread formed in the trigger housing.

The invention will be further explained with reference to the drawings. In detail, the schematic representation in:

1 a schematic representation of a trigger system according to the invention,

2 a schematic representation of the trigger system 1 with opened housing,

3 a schematic sectional view of the trigger system 1 .

4 a view from below of the trigger system 1 .

5 a schematic representation of a trigger system without magnet and detail, and

6 a schematic representation of a trigger system with magnet and detail.

The same reference numerals in the figures designate the same or equivalent elements.

1 shows a side view of a trigger system according to the invention 1 a firearm (not shown).

About a trigger 3 can be a related, in a trigger housing 4 pivotally mounted trigger 2 be actuated, with the trigger 2 around a trigger lever axis of rotation 5 is pivotally mounted.

The trigger in turn can be a trigger 7 actuate. This is the trigger 7 around a pawl rotation axis 6 swiveling, with the trigger latch 7 by contact with the trigger 2 and pivoting it about the pawl rotation axis 6 pivoted to mechanically trigger the shot of the firearm.

The bearing of the pawl rotation axis 6 is a in or on the trigger housing 4 arranged, on a grub screw 12 attached magnet associated with which magnetic forces on the bearing axis 10 the bearing of the pawl rotation axis 6 exercises in such a way that this backlash against the camp management 11 the bearing axis 10 is pulled.

In 2 is through the open hood 4 good to see that through the grub screw 12 the magnet 9 on the trigger housing 4 in terms of its distance to the bearing axis 10 by means of the thread 13 is held adjustable.

In 3 is a section along the line III 1 shown. It can be seen that the bearing axis 10 towards the magnet 9 is pulled and backlash at the magnet 9 facing side of the bearing guide 11 is applied.

4 shows a bottom view in which the grub screw 12 in the thread 13 is apparent.

5 shows a trigger system 1 without magnets, so the bearing axis 10 with game in the camp management 11 is held (see detail A), in contrast, is in 6 shown as the inventive arrangement, the play-free mounting of the bearing axis 10 in the warehouse management 11 by abutting on the magnet 9 facing side allows.
