Description

The invention relates to a lock system for a multi-barreled weapon according to the preamble of claim 1.

Such a lock system is known from DE 101 18 046 A1. This contains two slidably mounted on a lock plate strikers and a trigger device, the trigger pieces associated trigger rods, a trigger and a switching mechanism for automatically connecting the trigger with the trigger bar of the not yet released hammer after delivery of a first shot to release the second hammer by the Contains deduction. To create a universally usable lock system with high reliability of the switching mechanism includes a displaceable in the longitudinal direction of the gun changeover with a rotatably mounted on this rocker, which is spaced in the cocked position of both hammer pieces of the trigger rods and only after delivery of a first shot with the second Schlagstück belonging trigger bar for dispensing the second shot engages. Even if in this known lock system already a high security against double, i. an unwanted triggering of the second shot when firing the intended first shot is present in weapons is always a need for increased reliability and high reliability.

From the US 23 61 510 A is a trigger mechanism of a double-barreled handgun with two pivoting hammering pieces, two the striking pieces associated trigger rods and associated with the trigger rods trigger deduction known. The connection between the trigger and the two trigger rods is effected here by a transverse to the trigger lever which engages depending on the position of one or the other trigger rod for triggering the associated striking piece. The lever is arranged for this purpose at the front end of a guide pin which is mounted axially displaceably in a bore of a transversely movable to the trigger Umschaltstücks. About a arranged between the changeover piece and the lever compression spring, the lever is pressed in the direction of the two trigger rods. At the opposite to the guide part to the rear protruding rear end of the guide pin, a recoil block is fixed, through which the lever comes out of engagement with the trigger rods in a given by the delivery of a shot recoil. In this known trigger mechanism, however, the lever is brought out of contact with the trigger rods only during a backward movement of the recoil block relative to the changeover piece.

In one known from US 44 03 436 A trigger mechanism a switching device for selecting the first to be fired barrel is provided. The trigger is connected to the trigger levers via a connecting piece, which also serves as inertia block and ensures that the second trigger lever can be operated after delivery of a shot from the first run through the trigger for delivering a next shot from the second run.

From EP 0 592 103 A1 a lock of a double-barreled handgun with two pivotable striking pieces, the striking pieces associated trigger levers, a trigger and a selection device for selecting the firing order of the two runs is known. The selector includes a manually adjustable switch plate which cooperates with a forked selector for selectively actuating the trigger. The bifurcated selector is articulated laterally pivotable on an inertia block hingedly connected to the trigger.

The object of the invention is to improve the security against unwanted duplication in a lock system of the type mentioned again.

This object is achieved by a lock system with the features of claim 1. Advantageous embodiments and expedient embodiments of the invention are the subject of the dependent claims.

A significant advantage of the lock system according to the invention is that a security against unwanted duplication is ensured even if the shooter does not properly retract the weapon and therefore the weapon undergoes too long an acceleration phase during the recoil. By provided on the switching piece pendulum mass, the rocker is both in the acceleration and in the delay of the weapon shifted backwards relative to the changeover piece, so that the distance between a front nose of the rocker and the trigger rods is increased. As a result, an increased security against unwanted triggering of a second shot is achieved because the trigger bars can not be attacked by the rocker during the acceleration and deceleration phase of the weapon.

In the lock system according to the invention, the striking pieces and the firing pin in the longitudinal direction of the weapon are linearly displaceable, so that the most effective use of kinetic energy results at the same time compact design.

FIGS. 1 to 5 show a lock system of a bench-mounted shotgun in different positions. As is apparent from Figures 2 to 5, the lock system comprises two on a lower Baskülenteil (lock plate) 1 slidably guided, juxtaposed striking pieces 2 and 3 for actuating two superimposed striker 4 and 5. The two firing pin 4 and 5 are in one here not shown upper Baskülenteil axially displaceably guided and indicated only schematically in the drawings.

Each of the impact pieces 2 and 3 acted upon by a striking spring is assigned a respective striking piece holder 6 which is pivotable between a holding position and a release position and in each case has a trigger rod 7 cooperating therewith. The trigger bars 7 are pivotable via a trigger 8 from a blocking position in which they fix the respective hammer holder 6 in its holding position, in a release position in which they release the hammer holder 6 for forward movement of the respective hammer 2 and 3, respectively. In its holding position, the hammer holder 6 holds the respective hammer 2 or 3 in its retracted clamping position. In its release position, the impact piece holder 6 releases the impact piece 2 or 3, which is preloaded by a percussion piece spring, which can then impinge on the respective striking pin 4 or 5 in order to deliver a shot.

The displacement of the two hammer pieces 2 and 3 in the retracted clamping position via one in the Baskülenteil 1 pivotally mounted clamping lever 9, which cooperates with a tensioning rod, not shown here in a conventional manner such that the hammer 2 and 3 when tilting the barrel be moved over the tie rod and the associated clamping lever 9 in its retracted clamping position. In FIGS. 1 to 5, only the hammer holder 6 and the trigger bar 7 of the hammer 2 intended for the actuation of the upper firing pin 4 are shown. For the recognizable in Figures 2 to 5 hammer 3 a corresponding hammer holder and an associated trigger bar are provided.

As is apparent from Figure 1, the hammer holder 6 is pivotally mounted about a first transverse pin 10 on the lower Baskülenteil 1 and is pressed by a coil spring 11 in its upper holding position. The hammer holder 6 has an upper locking edge 12, against which the hammer 2 bears in the upper holding position of the hammer holder 6 and is held by this in the cocked position. The Schlagstückhalter 6 also has a lower locking projection 13 to which a front locking lug 14 of the pivotable about a second transverse pin 15 trigger bar 7 comes into abutment in its blocking position. By a coil spring 16, the trigger bar 7 is pressed into the blocking position. At its rear end, the trigger bar 7 has a downwardly facing web 17 and a rearwardly projecting lug 18. By lifting the rear end of the trigger bar 7, the front locking lug 14 can be lowered and brought out of engagement with the locking projection 13 of the hammer holder 6. As a result, the hammer holder 6 is released, whereby the hammer 2 can move forward under the action of the hammer spring. To the second transverse pin 15 also a sear 19 is pivotable, which engages in non-actuated trigger 8 in a corresponding recess 20 of the hammer 2 and only when lifting the rear end of the trigger bar 7 to release the hammer 2 swings down. This can ensure that the hammer 2 is blocked when not actuated trigger 8 and is released only when the trigger 8. In this way, an additional fall protection is enabled.

As already mentioned, the lock system has the above-described lock elements for the striking piece 2 in a corresponding manner also for the striking piece 3. Belonging to the hammer 3 Schlagstückhalter and the associated trigger bar are also pivotable about the transverse pins 10 and 15 respectively.

The trigger 8 is arranged according to Figure 2 about a trigger axis 21 movable on the lower Baskülenteil 1. He has at its rear end a through hole 22 for a withdrawal movement limiting retaining pin 23. On the trigger 8 is further guided on the front side of a further movable slider 24 in the longitudinal direction via a guide pin 25 slidably. The slider 24 is configured such that it comes into engagement either with the downwardly facing web 17 of the hammer 2 associated trigger bar 7 or with the corresponding web of the hammer 3 belonging trigger bar depending on the position. For this purpose, the slider 24 according to Figure 9a, b lateral webs 26a, 26b and Recesses 56a and 56b. By appropriately adjusting the slide 24 can thus be selected, whether the upper or the lower run is fired with the trigger 8 first.

In the rear position of the slider 24 shown in Figure 8a engages the downwardly projecting web 17 of the striking piece 2 associated trigger bar 7 in the actuation of the trigger 8 in the recess 56a of the slider 24 a. The downwardly projecting web 17 of the trigger piece 3 associated trigger bar, however, stands on the lateral web 26 b of the slider 24. Therefore, in the first actuation of the trigger 8 not the rear end of the trigger rod 7 shown here for Feigabe belonging to the hammer 2 Schlagstückhalters 6, but the rear end of the not recognizable here other trigger bar to release the trigger piece 3 associated trigger holder raised. In this case, the trigger bar releases the hammer holder, so that the impactor biased by the striker spring 3 can beat by the tension of the striker spring on the striker 5 belonging to the lower barrel. The first shot is therefore delivered at the position shown in Figure 8a of the slider 24 from a lower run.

In contrast, when the first shot is to be dispensed from the upper run, the slider 24 can be moved to a front position shown in Figure 8b. Then the downwardly projecting web 17 of the trigger piece 2 belonging to the trigger bar 7 is on the lateral web 26 a of the slider 24, while the corresponding web of the other trigger bar passes into the recess 56 b of the slider 24. At the first actuation of the trigger 8, the rear end of the trigger bar 7 is then lifted by the lateral web 26 a, whereby the hammer piece 2 belonging to the hammer piece holder 6 is released. As a result, the hammer 2 is released for firing a shot from the upper barrel.

For automatic switching from one run to the second run after delivery of the first shot, a switching mechanism shown separately in FIGS. 6a and 6b and 7a-c is arranged underneath the two striking pieces 2 and 3. As shown in Figures 6a and 6b, the switching mechanism includes a fork-shaped switching piece 27 which is slidably guided via a lower guide groove 28 on a corresponding projection of the lower Baskülenteils 1 in its longitudinal direction. The fork-shaped switching piece 27 contains two parallel legs 29 and 30, between which a rocker 31 is slidably disposed both in the longitudinal direction of the changeover piece 27 and about a transverse axis 32. To move the rocker 31 in the longitudinal direction of the changeover piece 27, the transverse axis 32 is guided in a transverse slot 33 extending through the non-contact piece 27. The rocker 31 is pressed by a compression spring 34 to the front. At its front end, the rocker 31 has a nose 35 for engaging under the rear projecting lugs 18 of the two trigger rods 7. The nose 35 is shown in Figure 1 on the rear end of the slider 24 and is pressed by pressing the trigger 8 upwards.

In a rear blind hole 36 of the Umschaltstücks 27, a spring 37 is arranged, which is supported according to Figure 1 with its rear end via a guide pin 38 on a rear wall 39 of the Baskülenteils 1. In a recess 40 on the upper side of the changeover piece 27, a pin-shaped switching part 41 is slidably disposed on both sides with a wedge-shaped pressure piece 42 projecting upwardly at the rear end by a predetermined angle. About a transverse pin 43, the switching part 41 is secured against falling out. By the wedge-shaped pressure piece 42, the position of the changeover piece 27 is determined in dependence on the position of the striking pieces 2 and 3, as will be explained in more detail below.

On the one leg 29 of the changeover piece 27, a pendulum mass 44 is articulated to the front and rear pivoted. The pendulum mass 44 shown in phantom in the side view of Figure 6a is rotatably guided in a corresponding opening 46 of the leg 29 via a guide pin 45 recognizable in the plan view of Figure 6b and is axially secured by a pin 47. On the guide pin 45 an inwardly projecting adjusting cam 48 is formed, which engages in a lateral recess 49 of the rocker 31.

As can be seen from FIG. 7a, an oblique bearing surface 50 is provided at the rear end of the recess 49, against which an oblique mating surface 51 of the adjusting cam 48 comes into abutment in the vertical starting position of the pendulum weight 44 shown in FIG. 7a. The inclined abutment surface 50 and the counter surface 51 are designed such that the pendulum mass 44 is pressed by the over the compression spring 34 forward biased rocker 31 in a predetermined vertical starting position. In this position is a rear end face 52 of the rocker 31 by the dimension L from an inner bearing surface 53 of the changeover piece 27 spaced. However, when the pendulum mass 44 pivoted forward or backward, the rocker 31 is pushed against the force of the compression spring 34 to the rear until the rear end surface 52 of the rocker 31 comes to rest against the inner abutment surface 53 of the changeover piece 27. When the pendulum mass 44 pivots forward as shown in Figure 7b, the rocker 31 is moved over a lower edge 54 of the adjusting cam 48 to the rear. Even if the pendulum mass 44 pivots backwards as shown in FIG. 7c, the rocker 31 is moved backwards via an upper edge 55 of the adjusting cam 48.

The lock system described above works as follows:

In the cocking position with the trigger 8 not yet actuated, the parts of the lock system according to the invention described above assume the position shown in FIG. The hammer 2 and the striking piece 3, which can not be seen here, are held in their withdrawn, tensioned position by the respective hammer holders 6. Also, the change-over piece 27 with the rocker 31 movably disposed thereon is held in the retracted position via the wedge-shaped pressure piece 42 of the switching part 41 resting on the rear side of the striking pieces 2 and 3. About the compression spring 34, the pendulum mass 44 is pressed into its vertical starting position shown, whereby the rocker 31 with respect to the Umschaltstücks 27 assumes the front starting position shown. In this position, the front nose 35 of the rocker 31 is spaced by a predetermined distance L from the rear lug 18 of the trigger rods 7 and thus there is no direct connection between the rocker 31 and the trigger rods 7 is present.

When the trigger 8 is actuated for the first time, depending on the position of the slide 24, either the rear end of the trigger piece 2 belonging to the striking piece 2 or the rear end of the trigger piece 3 is lifted over the lateral webs 26a and 26b of the slider 24, wherein the locking lug 14 located at the front end of the trigger bar 7 releases the associated hammer holder 6. In the retracted position of the slide 24 shown in Figure 1, the hammer 3 shown in Figure 2 is released for the actuation of the lower firing pin 5 in the first actuation of the trigger. If the hammer 3 moves forward under the action of the striker spring, this will give way Both sides pivotable switching part 41 of the changeover piece 27 laterally, whereby the changeover piece 27 can move by the action of the spring 37 relative to the Baskülenteil 1 forward in a position shown in Figure 5, in which the front nose 35 of the rocker 31, the rear approach 18 of the trigger bar 7 engages under. If the trigger 8 is then actuated a second time, the rear end of the trigger rod 7 is raised above the rocker 31, as a result of which the impact piece holder 6 belonging to the hammer 2 is released. If, on the other hand, the slider 24 is in the front position, the hammer 2 is first released for actuation of the upper firing pin 4 during the first actuation of the trigger 8. Then, the switching part 41 deviates to the other side and the switching piece 27 can also move forward by the action of the spring 37.

With reference to Figs. 2 to 5, the dynamic operations of the switching mechanism for avoiding doubling, i. an unwanted firing of the second shot during the recoil movement and springback of the weapon explained.

FIG. 2 shows the state of the lock system during the recoil with increasing to maximum acceleration. In this state, the switching piece 27 pushed forward by the spring 37 has accumulated on the lower base body part 1. In the acceleration to the rear, the pendulum mass 44 is deflected forward due to the inertia, with the result that the rocker 31 is moved relative to the changeover piece 27 to the rear. In the maximum front deflection of the pendulum mass 44 shown in Figure 2, the front nose 35 of the rocker 31 is spaced in the front position of the changeover piece 27 of the rear projection 19 of the two trigger rods 7 by the amount L3, so that in this state no second Shot can be delivered.

After completion of the acceleration starts the delay of the weapon. This ensures that, according to Figure 3, first the changeover piece 27 is pressed against the force of the spring 37 against the rear wall 39 of the Baskülenteils 1 and then the pendulum mass 44 is deflected back to the maximum rear pivot position shown in Figure 3. As a result, the rocker 31 is displaced relative to the reversing piece 27 against the spring 34 to the rear until it abuts the reversing piece 27. In this position, the front nose 35 of the rocker 31 is spaced from the rear lug 18 of the two trigger rods 7 by the amount L4, so that delivered no second shot in this state can be. The switching mechanism dwells in this state until the returning spring force becomes larger than the inertial force of the switching mechanism.

After the deceleration phase has expired, the switching mechanism again experiences a movement in the direction of the front end position. When the trigger 8 is actuated, as shown in Figure 4, the front nose 35 of the rocker 31, however, can not get below the neck 18 of the trigger bar 7, but is pressed against the rear edge, as shown by the arrow K. is. In this position, the second hammer 2 can not be released. Only after releasing the trigger 8, the front nose 35 of the rocker 31 can engage under the approach 18 of the trigger bar 7 for dispensing the second shot.

If, on the other hand, after expiration of the deceleration phase, the trigger 8 is not actuated, the front nose 35 of the rocker 31 can engage under the shoulder 18 of the trigger rod 7, as shown in FIG. Then, via the rocker 31, the trigger bar 7 can be actuated to dispense the second shot.
