Abstract

A firearm lock (1) comprises a cocking device for a hammer (3), a locking device (5) with a catch element (14) which maintains the hammer (3) in the cocked position, and a trigger (6). To ensure that the hammer is effectively maintained in the cocked position as well as silent loading and firing of the weapon on gentle triggering, the locking device (5) of the striker (3) is designed as a switching mechanism with a control element (10) and a catch element (14). When the weapon is locked, the catch element (14), for example a ball, engages in a recess (11) in the control element (10), for example a spring cylindrical pin, and presses against the hammer (3). When the hammer (3) is cocked, the catch element (14) engages in a recess (16) in the hammer and presses against the control element (10) displaced by a spring (12). In order to fire the weapon, the control element (10) is displaced by the trigger (6) until the catch element (14) re-engages in the recess (11) of the control element (10), thereby releasing the hammer (3).

Description

Weapon lock

The invention relates to a weapon lock according to the preamble of claim 1.

Such weapon locks are used e.g. in hunting weapons, competition weapons, revolvers, pistols and other rifles. The weapon lock in this case has an impact piece with a firing pin, which is cocked when the weapon is unlocked and is held in this cocked position by a locking device; common locking devices are e.g. So-called piercers, whereby the striking piece is held by latches which engage only a fraction of a millimeter in the striking piece. As a result, the striking piece can only be released by a very small force and the weapon can be fired, but this construction can trigger a shot due to a more or less strong vibration of the weapon. Attempts have been made to improve the locking device for the cocked impact piece, e.g. due to a mechanically complex construction from several individual parts. However, a reliable function is not given in the case of many interacting, precisely fitting individual parts, for example in the event of contamination or extreme temperature fluctuations. In addition, the pull-off resistance can only be regulated with difficulty in the known constructions. To prevent the weapon from being triggered unintentionally, the trigger resistance must therefore be set as a rule.

In the known constructions, be it simple latches or constructions made of several interlocking, precisely fitting individual parts, considerable noises occur when the weapon is cocked, which can interfere with certain types of hunting. The invention is based on the object of specifying a weapon lock of the type in question which, with simple construction, ensures reliable securing of the weapon in the cocked state, almost noiseless cocking and a soft, easily adjustable trigger.

This object is achieved according to the invention by the features specified in the characterizing part of patent claim 1.

Accordingly, a switching mechanism that is simple to manufacture is proposed for the locking device and does not require any latching pawls or interlocking individual parts that can be manufactured to fit. By supporting the locking element on the actuating element, the impact piece is held securely in the cocked position by positive and force locking. Triggering the weapon by vibrations is not possible with this construction. The locking element can e.g. a ball, a roller or the like. A spring-supported push pin is preferably used as the actuating element, but other designs, for example in the form of a roller, are also possible here.

In a weapon lock according to the invention, the trigger resistance can be adjusted very finely by adjusting the spring acting on the actuating element.

Since ball or rollers are preferably used as latching elements, which dip into correspondingly shaped recesses in the actuating element, an extremely soft deduction is also possible. This results in a practically silently stingable trigger e.g. for rifle shotguns and triplets.

The weapon lock according to the invention, including the safety device and the trigger, can be machined as a complete unit. put and mounted in a weapon. The entire mechanism can be used with single-barrel and multi-barrel weapons. The entire unit can be easily replaced.

In the construction according to the invention, a robust and simple and therefore reliable mechanism is used. Locking pawls or individual parts to be manufactured to fit precisely, as well as deflection levers, interception rods, etc. are not necessary.

The construction specified by the invention also noticeably reduces the manufacturing costs for weapon locks, with security not previously achievable. There are new, inexpensive and reliable options for the design of pierceable fume cupboards, fuses or automatic functions. In the case of repeating weapons, the possibility of manual tensioning with the weapon loaded is also possible. The weapon lock specified by the invention can be installed in simple weapons as well as in luxury side-lock weapons.

Further embodiments of the invention emerge from the subclaims.

The invention is explained in more detail in two exemplary embodiments with reference to the drawing. In this represent:

Figure 1 is a partially sectioned view of a Kipplauf¬ weapon in the area of the weapon lock;

FIG. 2 shows a partial view of the weapon lock in the secured state; Figure 3 is a partial view of the weapon lock in the cocked state;

Figure 4 is a partially sectioned view of a cylinder lock weapon in the area of the weapon lock and

Figure 5 is a partial view of the weapon lock according to Figure 4 in the cocked state.

In Figure 1, a weapon lock 1 an only indicated tilt barrel monkey 2 is shown. The weapon lock comprises an impact piece 3 with a firing pin 4, a locking device 5 and a trigger 6 cooperating with the locking device. The impact piece 3 is pivotally mounted about a shaft 7 and can be tensioned against the force of a compression spring 8. In the tensioned position, the striking piece 3 is held by the locking device 5. The locking device 5 has a cylinder pin 10 slidably mounted in a bore 9 with a recess 11, on one end of which a compression spring 12 acts. The tension of the compression spring 12 can be adjusted using an adjusting screw 13. A ball 14, which is located in a bore 15 perpendicular to the bore 9, interacts with the cylinder pin 10 as a locking element. The ball 14 is supported on the cylindrical pin 10 and on the lower end of the striking piece 3, which is designed in the shape of a circular arc. The striking piece also has a concave recess 16 in the shape of a circular arc.

The function of the weapon lock 1 described is as follows: In the secured position of the weapon lock shown in FIG. 1 and in FIG. 2, the ball 14 engages in the recess 11 of the cylinder pin 10 and is supported on the lower end of the striking piece 3. Due to the compression spring 12 acting on the cylinder pin 10, the ball 14 is pressed with a certain force against the striker 3, so that the striker is kept free of play; see. FIG. 2. If the weapon is cocked against the force of the compression spring 8 by pivoting the striker 3, the ball 14 finally dips into the recess 16 of the striker. At the same time, the cylinder pin 10 is pressed to the right in the direction of the trigger 6 by the compression spring 12. In the tensioned position of the weapon lock shown in FIG. 3, the ball 14 is supported on the cylindrical part of the cylinder pin 10 and is pressed onto the cylinder pin 10 by the striking element due to the force of the compression spring 6, so that here too a play-free one Bracket is present. The end of the cylindrical pin opposite the compression spring 12 is supported in this tensioned position on the trigger 6.

In order to trigger a shot, the cylinder pin 10 is pressed again by actuating the trigger 6 against the force of the compression spring 12 in the direction of the starting position shown in FIG. 1. As soon as the ball 14 reaches the area of the recess 11 in the cylindrical pin 10, the ball is pressed into this recess by the force of the compression spring 6, the striking element 3 being released at the same time and being pivoted into the starting position according to FIG. 1 by the compression spring 8. Hereby the weapon beats. Both the cocking of the weapon lock and the release of the striking piece 3 are practically noiseless. The trigger resistance can be adjusted very finely using the adjusting screw 13.

FIGS. 4 and 5 show a weapon lock 1 * of a repeating weapon 2 ', which is also only indicated. The Weapon lock has in this case a cylindrical striking piece 3 'which interacts with a locking device 5' according to the first embodiment. The trigger 6 'is also shown. The locking device in turn has a cylindrical pin 10 * with a recess 11 *, a compression spring 12 acting on this cylindrical pin 10 '. In the secured position of the repeating weapon 2 'shown in FIG. 4, the bullet 14' lies in the recess 11 * and is pressed against the cylindrical outer wall of the striking element 3 'without play. Triggering the weapon by actuating the trigger 6 'is not possible in this secured position.

To tension the weapon lock, the striking piece 3 * is pulled back against the force of a spring (not shown here) until the ball 14 ′ is in the region of a. conical taper 16 'of the striking piece 3'. The ball is pressed out of its recess 11 * by the force of the compression spring 12 *, the cylinder pin 10 'being simultaneously displaced in the direction of the trigger 6 *. The ball lies against the taper 16 ', so that the striker 3' is kept free of play in the tensioned position.

To trigger the gun the trigger is' activated, causing the cylinder pin 10 ^'against the force of compression spring 12' 6 is moved in Figure 5 to the left. As soon as the ball 14 'reaches the area of the recess 11', the ball 14 'is pushed into the recess 11 * by the tensioned striking piece 3 *, the striking piece 3' being released at the same time and the shot being triggered.

From the foregoing it can be seen that the otherwise known locking devices or punches for weapons are replaced by a simple and reliable switching mechanism.
