The inertial mass according to the invention is a pendulum weight (9) pivotable about a transverse axis (8) between a starting position and a securing position, through which the breaker (17) in the opposite direction to the pendulum weight (9) when knocking a first striking piece (2, 3) in the Separation position is pivotable.

Description

The invention relates to a weapon lock of a handgun according to the preamble of claim 1. The invention also relates to a handgun with such a weapon lock.

From the DE 10 2007 059 097 B3 is a gun lock with two arranged on a lock carrier arranged percussion pieces, each associated with each hammer piece trigger rod for holding or releasing the hammer, a trigger and a between the trigger and the trigger rods arranged breaker known. The breaker has two mutually parallel intermediate lever, which are arranged pivotably on a linearly displaceable within the lock carrier body. The main body with the rotatably mounted intermediate levers serves as inertial mass and is displaced after the delivery of a first shot such that between the intermediate levers and the trigger bars creates a gap. Such an interruption of the connection between the intermediate levers and the trigger rods is then when the weapon is slowed down at a caused by the recoil backward movement of the shoulder of the shooter or rebounds from this back to the front. In addition, belonging to the intermediate levers in the main body gate valves are arranged, which are designed so that they initially stop at a conditional by the recoil backward movement of the lock carrier due to their inertia and reach within the body in a front locking position. In this blocking position, the intermediate lever are blocked, whereby an unwanted triggering of another shot is prevented even during a conditional by the recoil backward movement of the lock carrier. In addition, the trigger includes a slidable separator which is slidable relative to the trigger between a rear operating position for connecting the trigger with the intermediate levers and a front separating position for separating the trigger from the intermediate levers by its inertial mass. Thereby, a double, ie the unwanted triggering of a second shot when firing the intended first shot, can be prevented. However, this known weapons lock is relatively complex and has a variety of mutually movable and matched parts. The object of the invention is to provide a weapon lock and a handgun with such a weapon lock, which ensures a high security against unintentional release of a second shot in the delivery of a first shot with fewer parts.

This object is achieved by a gun lock with the features of claim 1 and by a handgun having the features of claim 14.

In the weapon lock according to the invention, the inertial mass consists of a pivotable about a transverse axis between a starting position and a securing position pendulum weight through which the breaker is pivotable when knocking a first hammer in the opposite direction to the pendulum weight in the disconnected position. By the opposite pivotal movement of pendulum mass and breaker can be ensured that after the delivery of a first shot, the connection between the trigger and the trigger bars is interrupted both in the acceleration and in the deceleration phase, so that a high level of security against the unwanted delivery of second shot exists. The separate execution of the latched breaker and the pendulum weight as separate parts also offers the advantage that the usually sensitive detents of the breaker do not come with the moving front and rear pendulum weight in contact and therefore less stressed.

Advantageous developments and advantageous embodiments of the invention are the subject of the dependent claims.

• Eine Steuerung des Unterbrechers kann in vorteilhafter Weise dadurch erfolgen, dass die Schlagstücke eine Steuerfläche enthalten, die mit Anlageflächen des Pendelgewichts so zusammenwirken, dass das Pendelgewicht beim Abschlagen eines Schlagstücks in die Sicherungsstellung bewegt wird und dabei den Unterbrecher in entgegengesetzter Richtung nach vorne in die Trennstellung bewegt.

Thus, the opposing pivotal movement of pendulum weight and breaker in an expedient embodiment, for example, be achieved in that the pendulum weight has a lower part with a relation to the axis of rotation projecting lug to rest against a stop surface of the breaker. The pendulum weight may also include a widened upper part with a front recess for receiving the trigger bars:

• A control of the breaker can be carried out in an advantageous manner in that the hammering pieces contain a control surface, the so with bearing surfaces of the pendulum weight cooperate, that the pendulum weight is moved when knocking a striking piece in the securing position and thereby moves the breaker in the opposite direction forward to the release position.

In a preferred embodiment, the pendulum weight is arranged rotatably about the transverse axis in the lock carrier and the breaker rotatable about a further transverse axis in a recess of the trigger.

In a further advantageous embodiment, the trigger bars are designed as a two-armed lever with an obliquely upwardly facing upper arm and a lower arm. On the upper arm of the two trigger rods can each have a first catch for engagement with a first mating latch on the top of the respective hammer pieces and on the lower arm of the two trigger rods can each have a second mating latch for engagement with a protruding central latch or recessed side latches on the Be provided back of the breaker. The first catch on the trigger bars may e.g. be designed as a latching groove and the associated first counter-latching on the striking pieces as a latching nose. The second mating latch on the trigger rods can also be designed as a latching lug, the central latch on the circuit breaker can be designed as latching surface on a rearwardly projecting nose and the lateral detents can be formed as latching surfaces on lateral recesses of the circuit breaker.

An automatic switchover can be made possible in a further advantageous embodiment in that the breaker on its rear side recesses or recesses for receiving the nose of the cut-off piece belonging to the trigger bar contains. If the pendulum weight returns to its initial position after the delivery of a first shot, thereby one of the lateral detents of the switch can get under the trigger bar of the not yet severed percussion piece, so that they can be knocked off by a renewed actuation of the trigger.

The invention also relates to a double-barreled shotgun or other handgun equipped with such a weapon lock.

This in FIG. 1 illustrated in a perspective gun lock a hand gun, especially a shotgun, contains a lock plate referred to as lock plate 1, are arranged on the two adjacent strikers 2 and 3 between seen in the weft direction rear clamping position and a severed front position movable. The right seen in the firing direction and in the representation of FIG. 1 The front striking piece 2 is in a cut off front position and the left hammer 3 seen in the weft direction is shown in a cocked retracted position. Both striking pieces 2 and 3 are mounted rotatably about a striking piece axis 4 on the lock carrier 1. By impact springs 5, the hammer 2 and 3 are pushed forward in the severed position. The impact springs 5 are clamped between the lock carrier 1 and the respective striking pieces 2 and 3.

Seen in the weft direction behind the two striking pieces 2 and 3 are also on the lock carrier 1 also two also juxtaposed and the respective Striking pieces 2 and 3 for their support in the clamping position or release associated trigger rods 6 and 7 rotatably arranged about a transverse axis 8. Rotatable about the transverse axis 8, a pendulum weight 9, which is explained in greater detail below, is also mounted on the lock carrier 1. Furthermore, a trigger 11 rotatable about a trigger axis 10 and at the bottom of the lock carrier 1, a trigger guard 12 are arranged on the lock carrier.

How out FIG. 2 shows, the trigger 11 has a projecting into a recess 13 on the underside of the lock carrier 1 peel sheet 14 and from the lock carrier 1 down projecting trigger reins 15. In a recess 16 of the trigger blade 14, an interrupter designed as an interrupter 17 is rotatably mounted about a transverse axis 18. The breaker 17 is pressed by a arranged in the weft direction in front of the transverse axis 18 arranged spring 19 to the rear. With the help of a FIG. 4 shown trigger spring 20, the trigger 11 is pressed into a front starting position.

In FIG. 1 It can be seen that the two identically formed trigger rods 6 and 7 are designed as two-armed levers with an obliquely upwardly facing upper arm 21 and a lower arm 22. With the help of two seen in the weft direction behind the transverse axis 8 and arranged in FIG. 6 recognizable, spring-loaded pressure pin 23, the two trigger rods 6 and 7 are acted upon so that the upper arm 21 is pressed by the spring-loaded pressure pin 23 down. On the upper arm 21 of the two trigger rods 6 and 7 respectively a first latch 24 is provided for engagement with a first counter-latching 25 on the upper side of the respective hammer 2 and 3 respectively. The first latch 24 on the trigger rods 6 and 7 is executed in the embodiment shown as a latching groove and the first counter-latching 25 on the striking pieces 2 and 3 as a latching lug. At the free end of the lower arm 22 of the two trigger rods 6 and 7, a second counter-latch 26 is provided for engagement with a protruding central latch 27 or set back lateral latches 28 on the breaker 17. The second counter-latch 26 on the trigger bars 6 and 7 is designed in the embodiment shown as a latching lug. The central catch 27 is designed as a latching surface on a rearwardly projecting nose and the lateral catches 28 are designed as latching surfaces on lateral recesses of the breaker 17.

About one arranged on the underside of the lock carrier 1, in FIG. 4 shown slide 29, the breaker 17 can be moved transversely to the lock carrier 1 so that the central latch 27 on the breaker 17 either passes under the counter-latch 26 of the first or second trigger bar 6 and 7 respectively. As a result, it can be determined whether the right or left hammer 2 or 3 is knocked off first during the delivery of the first shot.

From the FIGS. 1 and 2 shows that the pendulum weight 9 arranged between the two trigger rods 6 and 7, slender lower part 30 with a respect to the transverse axis 8 in the weft direction forward projection nose 31 and an upwardly projecting and widened upper part 32 with a front recess 33rd for the arms 21 and 22 of the two trigger bars 6 and 7 contains. The pendulum weight 9 also has at its slender lower part 30 a arranged in the weft direction behind the transverse axis 8 and in FIG. 2 recognizable approach 34 on. The pendulum weight 9 is rotatable about the transverse axis 8 and can between a in FIG. 2 shown front starting position and a in FIG. 4 be shown pivoted rear securing position. By a clamped between the lock carrier 1 and the shoulder 33, spring-loaded pressure pin 35, the pendulum weight 9 is seen in the direction of the shot pushed forward to its original position.

The forwardly projecting nose 30 of the pendulum weight 9 is formed such that in the in FIG. 2 shown starting position between the nose 31 and the breaker 17 is a gap. At the nose 31 of the pendulum weight 9 facing back, the breaker 17 has a lower stop surface 36 and upper recesses 37.

At the two striking pieces 2 and 3, a control surface 38 is provided in each case, with the in FIG. 1 shown abutment surfaces 39 at the upper part 32 of the pendulum weight 9 cooperates so that the pendulum weight 9 is accelerated when knocking a hammer 2 or 3 to the rear to move to a blocking position and moves the breaker 17 in the opposite direction forward to the disconnected position.

In the following, the operation of the weapon lock described above is based on the FIGS. 2 to 6 explained, wherein the FIGS. 2 to 5 show the trigger mechanism with the gun in the direction of shot right 2 and in FIG. 6 the trigger mechanism with the two striking pieces 2 and 3 is shown. In FIG. 6 is seen in the firing direction left hammer 3 knocked off, while the other hammer 2 is still in the cocked position.

In FIG. 2 is the weapon lock with the right shot in the direction of strike 2 shown in tense and ready to launch position. The pendulum weight 9 is pressed by the spring-loaded pressure pin 35 in the release position. In the in FIG. 2 shown release position of the widened upper part 32 of the pendulum weight 9 is pivoted forward and between the nose 31 at the lower end of the pendulum weight 9 and the lower stop surface 36 on the breaker 17 is a distance. The acted upon by the striking spring 5 striking piece 2 is held by the first latch 24 on the pressed by the pressure pin 23 down the upper arm 21 of the trigger bar 6 in the retracted clamping position. The arranged on the lower arm 22 of the trigger bar 6 mating latch 26 is engaged by the central latch 27 on the breaker 17.

If the trigger 11 at the in FIG. 1 shown position, the breaker 17 raises the lower arm 22 of the trigger bar 6 according to FIG. 3 on, whereby the upper arm 21 of the trigger bar 6 is raised so that the first catch 24 of the trigger bar 6 out of engagement with the counter-latch 25 on the hammer 2 passes and this under the force of the striker spring 5 forward on the firing pin, not shown for delivery can hit a shot.

Out FIG. 3 It is apparent that the pendulum weight 9 when knocking the hammer 2 by the hammer 2 provided on the control surface 38 to the rear in an in FIG. 4 shown securing position is pivoted. The nose 31 comes at the lower end of the pendulum weight 9 to rest against the lower stop surface 36 of the breaker 17 and turns this seen in the weft direction against the force of the spring 19 forward, so that the breaker 17 comes out of contact with the second trigger bar 5 and thus belonging to the second hammer 3 second trigger bar 5 is not actuated via the breaker 17 and no second shot can be delivered.

Even if the pendulum weight 9 is moved, for example, by manual reset or by falling over, the weapon, by vibrations or in a rebound of the weapon from the shoulder of the shooter after the delivery of a shot in the securing position, the breaker 17 comes out of contact with the trigger bars, so no shot can be fired at this stage.

Only when the pendulum weight 9 after the delivery of a first shot back into his in FIG. 5 As shown starting position returns, the breaker 17 can move back to its release position. In this case, the nose 31 of belonging to the severed hammer piece trigger bar engage in the corresponding recess 37 on the back of the breaker 17. In FIG. 6 this is shown for a position in which the left hammer 2 seen in the weft direction is cut off, while the right hammer 3 is still in a cocked position. If the pendulum weight 9 moves after the knocking of the first hammer 2 from the securing position back to the starting position and the breaker 17 opposite to it again from the disconnected position to a release position, the nose 31 of belonging to the severed hammer 2 trigger bar 7 in the corresponding Engage recess 37 on the back of the breaker 17 so that the breaker 17 with one of the side latches 28, the nose 31 of the belonging to the other hammer 3 trigger bar 6 can engage under. Only then, by re-pressing the trigger 11, the trigger bar 6 can be rotated via the breaker 17 to release the second hammer 3.
