Description

Technical field

The invention relates to handguns with a bolt system according to the restrictive part of paragraph 1.

State of the art

Such handguns are known from patent document EP 2068110 A2. It includes a shutter system with two firing pins movably located in the system box, with firing pads holders for securing or unlocking the firing pins, with locking levers corresponding to the locking levers, intermediate levers for interacting with the locking levers, actuated by the trigger device, and inertial mass, placed with the possibility of movement inside the system box and connected to the intermediate levers, to interrupt the connection between KSR levers and lock arms with undesirable impacts. In this known handgun, the intermediate arms are located in the main body, which, together with the block-shaped guide part, extends in the system box with the possibility of moving in its longitudinal direction. The main body and the guide part in the form of a block form an inertial mass that controls the contact of the intermediate levers with the locking levers or the interruption of this contact. However, this fuse to prevent unwanted firing is effective only when striking in the longitudinal direction of the weapon and should primarily prevent doubling i.e. unwanted firing of the second shot with the planned first shot.

From the patent document DE 102004041054 B3 there is known a bolt lock system for multi-barrel weapons with at least two strikers arranged to move in the receiver, with a striker holder corresponding to each of the strikers and a trigger mechanism that contains trigger levers, a trigger device and switching mechanism. The switching mechanism has a switching element, made with the possibility of movement on the receiver, with a balancer placed movably on the switching element. A pendulum mass rotatable is placed on the switching element in the corresponding hole by means of the guide pin. The pendulum mass is connected to the balancer in such a way that when the pendulum mass deviates from a predetermined initial position due to the acceleration or deceleration of the switching element, the distance between the balancer and the release levers increases.

DE 101 180 046 A1 discloses a multi-barrel shotgun shutter system with a switching mechanism for automatically connecting the trigger device to the trigger lever of an unblocked second firing pin after firing the first shot. The switching mechanism comprises a main body configured to move the gun in the longitudinal direction, with a trigger placed on the housing with the possibility of rotation and actuated by a trigger device, the trigger in the cocked state of the hammer is located at a distance from the trigger arms and only with the end of the elastic recovery of the gun is brought into interaction with the trigger lever, related to the second drummer, for the production of the second shot.

Patent document DE 19749290 A1 discloses a trigger mechanism for double-barreled shotguns with two strikers, each of which is held in a cocked position by a corresponding locking lever. The trigger mechanism includes a common trigger device and a switching element configured to rotate around the first axis of rotation on the trigger device plate, which after the first exposure to the trigger device comes under the action of a spring into the switching position and, when the trigger is pressed for the second time, releases the second locking device lever. The pendulum mass interacting with the switching element is pivotally connected to the shutter box with the possibility of rotation about a second axis of rotation parallel to the first axis of rotation. Thanks to the pendulum mass, the switching element both in the movement of the recoil of the gun and in the subsequent elastic recovery is held in a passive position, so that doubling is effectively prevented.

From the patent document DE 4244168 C1, a shotgun shutter with a movable safety part is known which, in the safety position, covers the key of the lock so that it cannot come out of the lock in the hammer. The safety part by means of the transverse axis is rotatably placed on the lock plate and in the direction of rotation is under the action of a spring force, which holds the safety part out of interaction with the lock key. The spring force and the moment of inertia of the safety part rotatably placed around the transverse axis are selected so that as a result of recoil from the fired shot, the safety part temporarily rotates to the safety position based on its inertia, overcoming the spring force.

Disclosure of invention

The objective of the invention is to create such a handgun mentioned at the beginning of the type, which provides higher protection against unauthorized shots even when a handgun falls and in various situations of capsizing.

This problem is solved with handguns with the signs of paragraph 1.

The handgun according to the invention comprises a bolt system that comprises at least one firing pin arranged to move in the firing box, a firing pin holder for securing or unlocking the firing pin, a corresponding locking lever for the firing pin holder, actuated by the trigger device, an intermediate lever for interactions with the locking lever and the inertial mass placed with the possibility of movement inside the system box and connect with intermediate levers to interrupt the connection between the intermediate levers and the locking levers in case of undesired impacts. The intermediate lever is rotatable in the trigger mechanism, and the inertial mass is made in the form of a pendulum mass located in the shutter box with the ability to move along the transverse axis in the groove, with at least one guide surface designed to fit to the upper arm of the intermediate lever pressed to the guide surface. Due to the connection through the groove, the pendulum mass has the ability not only to turn up and down from its original position, but also to move backward when viewed in the direction of the shot, thereby removing the intermediate lever connected to the pendulum mass through the guiding surface from the connection with the locking lever. As a result of this, the safety device is effective not only in impacts acting in the longitudinal direction of a handgun, but also in shock or shock in other directions. It is possible to block several directions of movement and thus increase safety in various situations of falling or tipping over. The safety system acts directly and is built compactly, with a high degree of security.

Suitable embodiments of the invention and preferred embodiments of the invention are the subject of the dependent claims.

Thus, in a particularly favorable embodiment, an intermediate lever is possible comprising a lower lever arm located at an angle to the upper arm of the lever, which is influenced by a return spring pressing the front surface of the upper arm of the arm against the guide surface of the pendulum mass. The intermediate lever, as appropriate, is placed with the possibility of rotation on the trigger mechanism through the protruding inward support pin.

In a further advantageous embodiment, the intermediate lever has a front locking edge for engaging with the protruding protrusion of the locking lever. In the pendulum mass, a side recess is preferably provided for receiving an intermediate arm therein.

The guide surface on the pendulum mass preferably interacts with the front contact surface of the intermediate lever so that the intermediate lever rotates the pendulum mass to its original position to raise the locking lever, and the intermediate lever when the pendulum mass rotates relative to the initial position and the pendulum mass is shifted in the direction opposite to the direction of the shot comes out of the connection with the locking lever.

Another preferred possibility is that for cocking the spring located in the hammer, the cocking lever comprises a lever arm for holding the pendulum mass in the upper abutment position. Thus, using the shoulder of the cocking lever, it is possible to press the pendulum mass, for example, with an unarmed handgun, to the abutment surface and thereby prevent movement or knock of the pendulum mass in an unarmed handgun.

Brief Description of the Drawings

Further features and advantages of the invention result from the following description of a preferred embodiment based on the drawings, in which:

FIG. 1 handgun shutter system in a perspective view, front view from the left;

FIG. 2, a shutter system of FIG. 1 in a perspective view, rear right view;

FIG. 3 is a longitudinal section through the shutter system of FIG. 1 cocked; and

FIG. 4 is a longitudinal section through the shutter system of FIG. 1 in the uninvolved position.

The implementation of the invention

In FIG. 1-4 shows in various views the upper part 1 of the shutter box 2 or system box 2 of a handgun, here made as a weapon with a folding barrel, with a shutter system. The shutter system in the shown embodiment contains two locks located next to each other with corresponding drummers 3 and 4, which extend inside the system box 2 with the possibility of moving parallel to each other and are intended to act on the strikers not shown here.

As follows from FIG. 3 and 4, each of the impactors 3 and 4 has a corresponding groove 5, in which the shock spring 6 and the shock spring pin 7 adjacent to the rear end of the shock spring 6 are located. To tension both shock springs 6, both shock spring pins 7 are connected to each other by a lever 9 of the platoon, located between both strikers 3 and 4 and made to rotate around the transverse axis 8, and the transmission axis 10, passing in the transverse direction through both pins 7 of the cocking mechanism and through the lever 9 of the cocking. The platoon lever 9 is made in the form of a curved L-shaped two-shouldered lever with the upper arm 11 protruding upward from the strikers 3 and 4, and with the lower arm 12 passing at an angle to it. The platoon lever 9 is rotatable by the platoon handle 13, which is moved to the upper side of the upper part 1 of the system box 2. For this, a transverse rod 14 is placed in the lower part of the cocking handle 13, which enters the groove 15 in the upper arm 11 of the cocking lever 9, protruding upward from the strikers 3 and 4.

Attached to both drummers 3 and 4 is the one shown in FIG. 1 and 2 on both sides of the trigger mechanism with respective holders 16 and 17 of the strikers, rotatable between the holding position and the unlocking position, and with the locking levers 18 and 19, each of which interacts with the respective holder 16 or 17 of the striker. The action of both locking levers 18 and 19 for unlocking the drum holders 16 and 17 is effected by means of respective intermediate levers 20 and 21, which are pivotally mounted on two separate triggers 22 and 23. Both triggers 22 and 23 are placed in the system box 2 rotatably around those shown in FIG. 3 and 4 of the transverse rods 24 and 25 and have two triggers 26 and 27 located one after another.

In FIG. 1 and 2, it is seen that both firing holders 16 and 17, located next to each other, are placed in the system box 2 with the possibility of rotation around the transverse rod 28. Each of them has an upper locking latch 29 or 30 for attaching the corresponding firing pin 3 and 4 and the lower latch 31 and 32 for interacting with one of the stops 33 or 34 on the locking levers 18 and 19. The latches 31 and 32 on the holders 16 and 17 of the strikers are made in the form of locking latches, and the stops 33 and 34 in the form of locking grooves on the lower surface rear when viewed in the direction of shots, shoulders 35 and 36 of both locking levers 18 and 19, made as two-arm rotary levers. On the lower surface of each of the front, when viewed in the direction of the shot, the shoulders 37 and 38 of both locking levers 18 and 19 are affected by the corresponding pressure spring 39 and 40, by means of which the rear shoulder 35 or 36 of the locking lever 18 or 19 is pushed down. Both locking levers 18 and 19 are rotatably mounted in the system box 2 around the one shown in FIG. 3 transverse rods 41.

From FIG. 3 it can be seen that the intermediate lever 20 serving as a chopper is rotatably placed around the inwardly extending finger 42 in the plate 43 of the trigger 22. The L-shaped intermediate lever 20, like the intermediate lever 21 not shown here on the other side, has a protruding upward the shoulder 44 and directed forward, when viewed in the direction of the shot, the lower shoulder 45. By means of a return spring 46 acting on the lower shoulder 45 of the lever, the intermediate lever 20 is pressed counterclockwise in the direction shown and FIG. 3, a standby position in which the front locking edge 47 on the upwardly extending shoulder 44 of the intermediate lever 20 supports a protruding protrusion 48 on the rear shoulder of the lever 35 of the locking lever 18.

In addition, in the system box 2, there is a pendulum mass 49, which is rotatable around a transverse axis 50 placed in the system box and shown in FIG. 1. The pendulum mass 49 has on the rear side visible in FIG. 1 slot 51, which includes an oblique angle of the lower arm 12 of the cocking lever 9.

As shown in FIG. 3, the pendulum mass 49 on both of its lateral surfaces has a recess 52 with an inclined guide surface 53 for contacting the front, when viewed in the direction of the shot, contact surfaces 57 of the upward shoulders 44 of both intermediate arms 19 and 20. The pendulum mass 49 by means of the groove 54 located in the front region of the pendulum mass 49 is placed on the transverse axis 50 and as a result is arranged to move relative to the transverse axis 50. On the upper side of the pendulum mass 49 is located shock absorbing th element 55, consisting of rubber or other elastic material. In addition, on the rear side of the pendulum mass 49 is a pin-latch 56, passing through the slot 51.

Hereinafter, based on FIG. 3 and 4, which show the left, when viewed in the direction of the shot, the lock with the trigger for acting on the left firing pin 3, the principle of operation of the shutter system described above is explained. The right lock with a trigger for acting on the right drummer 4, is arranged accordingly.

In FIG. 3 handguns are shown cocked and ready to fire. The cocking handle 13 is pushed forward, so that the shock spring 6 is tensioned by the shock spring pin 7 and the cocking lever 9. The hammer 3 under the action of the shock spring 6 is adjacent to the locking latch 29 of the holder 16 of the retainer held in the locked position by the locking lever 18. The holder 16 of the retainer 16 is held in the upper locking position due to the interaction of the lower retainer 31 with the stop 33 in the rear shoulder 35 of the locking lever 18, pressed down pressure spring 39. With the idle position of the trigger 22 and the weapon in a quiet position, the protruding protrusion 48 of the locking lever 18 is supported by the front locking edge 47 n and the upwardly extending shoulder 44 of the intermediate arm 20. With the front contact surface 57 of the upper arm 44 of the intermediate arm 20 pressed against the guide surface 53, the pendulum mass 49 is held in the initial position shown in FIG. 3. The lower arm 12 of the cocking lever 9, angled, is deflected downward within the slot 51 in the pendulum mass 49, so that the pendulum mass 49 can rotate up and down, as well as move backward along the groove 54. If the release device 22 is activated in this position , then the rear shoulder 35 of the locking lever 18 is lifted by the intermediate lever 20, so that the lower latch 31 of the holder 16 of the latch leaves the interaction with the stopper 33 of the locking lever 18, the hammer 3 and gets the opportunity under the action of the force of the shock spring 6 strike forward on an unshocked striker to produce a shot.

If the weapon after an fired shot receives an undesirable blow, for example, as a result of a fall, shaking, or ricochet from the shooter's shoulder, the pendulum mass 49 is able, depending on the direction of the strike, to turn upward or downward around the transverse axis 50 or also to move backward along the groove, seen in the direction of the shot, and then the locking edge 47 of the intermediate arm 20 in accordance with FIG. 4, the guide surface 53 of the pendulum mass 49 is brought out of contact with the protrusion 48 of the locking lever 18, and thus the intermediate lever 20 can no longer act on the locking lever 18.

The lower shoulder 12 of the platoon lever 9, when the handgun is unengaged, is able to rotate the pendulum mass 49 by means of the locking pin 56 to the upper abutment position and, by means of the shock-absorbing element 55, bring it into the abutment position on the lower surface of the projectiles 3 and 4, as shown in FIG. . 4. In this upper abutment position, the locking edge 47 of the intermediate lever 20 is also divided with the locking lever 18, so that the trigger 22 cannot act on the locking lever 18. Thus, when the gun is not raised, the handgun is also in a safe position.

The shutter system described above is suitable not only for handguns with two percussion instruments located next to each other, but is also applicable for handguns having only one percussion gun.
