The invention relates to a trigger device for rifles with an auxiliary device for pulling the Trigger latch by means of a pull lever.

With known trigger devices on competition rifles, pulling the trigger as far as the pressure point, the so-called "advantage", is perceived by the shooter as a nuisance. The shooter should focus simultaneously on two things: the target and the gun, because he has his finger gen movement to the fine-standing pressure point, to seize without it. The way to the pressure point of the trigger cannot be omitted, however, since a rifle is in a dangerous state without preference, because the levers holding the firing pin then only overlap by a very small fraction of a millimeter. If the weapon is jolted or when it is being reloaded, a shot could be released by itself.

In order to avoid finger travel to the pressure point, hunters often still use engravers. Engravers who are authorized to use the difficult trigger devices on hunting rifles, are unsuitable for competition rifles. Their large leverage requires a long shot development time. To do this, striking them at right angles to the soul axis of the rifle creates a shock. Both phenomena worsen the shooting result.

A trigger lock is known in which a hollow pin counteracts by pivoting the trigger lever the action of a retraction spring is pivoted so that a nose of the hollow pin is on a head of the trigger is supported.

Also known is a trigger device that can be used either with or without the use of the trigger lever can be used and a changeover element for changing the spring loading of the sear has, so that the spring of the sear is moved once when the trigger is actuated is, while in the other position of the changeover the trigger against the action the spring is pivoted.

In contrast, according to the invention, the trigger of a trigger device known in principle, as it is used in competition rifles, a coupling lever assigned to it by a by means of ■ the pull lever rotatable control element cam-controlled with the catch lever of the firing pin cooperates so that it is possible "to move the trigger to the pressure point and fix it there. Similar to stabbing with hunting rifles, this only happens when the shooter has the rifle has at the ready. A trigger device for rifles can be set with a push button

Helmut Liebmann, Ulm / Donau, has been named as the inventor

the detent lock released and the lancing device switched off again, so that the trigger device acts as a pressure point trigger. Even when loading through, i.e. when pulling back the chamber, the changeover takes place in the state of the effectiveness of the pressure point trigger, which is an advantage of the Subject of the invention is compared to the known. In addition, the subject matter of the invention the advantage that it is particularly space-saving.

In a further embodiment of the invention, the control member has an eccentric in the form of a shaft on which the cam of the coupling lever rests. Furthermore, a pin of the shaft and a fork are used of the pull lever as a coupling between the pull lever and the shaft, with the shaft having a detent and the pawl, the nose of which serves as a stop for the catch lever, assigned a second nose are, so that the catch and the nose in the lancing position of the trigger device a rotation lock for the wave form.

Finally, according to the invention, the pawl is an actuator and the one for opening the lock serving chamber ring a chamber wart to disengage the pawl from the notch of the shaft assigned, which ensures the resetting of the lancing device in a particularly simple manner is.

An exemplary embodiment is shown in the drawing.

In the basic position, the pulling lever 2 rests on the stop pin 4 according to Fig. 2 limits the stop pin 5. In this position, the catch lever 11 is about to be released; the trigger pawl 3 (Fig. 1). The catch lever 11 is released by actuating the trigger lever 1. ;; .. '..

Further parts of the trigger device are the auxiliary lever 9, which is supported by a compression spring 7 against the trigger pawl 3 and against the shaft 8, as well as the pawl 10. Between this pawl 10 and the catch lever 11 isJ-. a compression spring 12 is used. ..., ._ ·.

The auxiliary device (piercing device) consists of the advance lever 2 (piercing lever), which is loaded by the compression spring 13 and is coupled by means of the fork 2 a to the pin 8 b of the freely mounted shaft 8 (Fig. 7), as well as the coupling lever 14, which transfers a rotation of the shaft 8 from the basic position I (Fig. 9) to the pre-drawn position II (Fig. 10) on the trigger device and moves it. The angled lever 6 carrying the cam 6a (pressure point cam) is connected to the trigger lever.l, which has the cam 1 α for the trigger pawl 3.

The compression spring 7 is assigned the task of applying the trigger pawl 3 to the cams Io or 6a. It must be designed to be strong so that it can safely return the trigger pawl 3 to its basic position retrieved when the shooter has moved the trigger 1 to the pressure point, but still does not pull the trigger.

The trigger device can be operated independently of the auxiliary device. If the extraction device is used without using the auxiliary device, the shaft 8 does not experience any rotation. If the trigger pawl 3 is therefore moved by the angle lever 6 until the pressure point is reached when the trigger lever 1 is actuated, the catch lever 11 is released and the firing pin 19 with the nose 19 a can snap in the direction M and ignite the cartridge. During this process, the trigger 1 covers a relatively long distance.

However, if the shooter wants to use the auxiliary device (lancing device), then he pushes the pull lever 2 from the basic position according to Fig. 2 in the direction of arrow D forwards, so that the fork 2 a of the pull lever 2 rotates the shaft 8 clockwise and the Cam 14 a of the coupling lever 14 adjusted under the influence of the eccentric 8 a of the shaft 8 lifting. When the actuation end position of the pull lever 2 is reached, the trigger pawl 3 and the catch lever 11 loaded by the firing pin spring and the spring 17 are at pressure point to one another. Pulling the trigger 1 in direction E then triggers the shot, the trigger 1 only covering a very small distance and, which is essential, the moving parts of the auxiliary device are not moved.

If the shooter uses the auxiliary device and presses the pull-up lever 2 out of the basic position according to FIG. 2 in the direction of arrow D , then the nose 10 b of the pawl 10 engages

ίο a notch 8a ″ of the rotating shaft 8 (see Fig. 1) so that it cannot turn back. The trigger lever 1 is held in the pressure point position. When the shaft 8 is rotated by the pulling lever 2, the free end jumps the U-shaped, made of sheet metal and one of the abutment for the compression spring 7 forming auxiliary lever 9 in the surface 8 a c having the groove of the shaft 8 in. Here, the tension of the compression spring 7 decreases.

So that the trigger of the rifle in the state of the stabbing position when loading is not accidentally in this position, in which a shock can easily result in the unintentional downward pivoting of the catch 11a of the catch lever 11 and thus the z. B.

can also cause the shooter to endanger the firing of a projectile, is triggered, the nose 10α on the pawl 10 is provided as a securing element, which protrudes into the path of the chamber ring 15 (Fig. 3). When the chamber ring 15 is moved in the direction N (Fig. 1) through the bolt handle 15 b, ie when the lock is opened, one of the two chamber lugs 15 α presses the nose 10 α downwards. The nose 10 & the pawl 10 disengages from the notch 8 d of the shaft 8, so that the shaft 8 springs back into the basic position according to FIG. 2 under the action of the compression spring 13 on the pull-up lever 2. The same process can also be initiated by pressing the conical, spring-loaded push button 16 (Fig. 1), which protrudes laterally from the stock of the rifle. If the shooter wants to set down the rifle, he can therefore let the trigger lever 1 jump back from the pressure point position into the basic position of the trigger device at any time by pressing this push button 16.

The threaded pin 18 is used to adjust the position of the trigger lever 1 relative to the coupling lever 14th
