Description

The invention relates to a trigger device of a handgun such as EP 1 387 140 A1 mentioned.

From the DE 20 2015 101 485 U1 A trigger mechanism for a handgun is known with a trigger that is pivotably arranged in a trigger housing between a starting position and a release position, a sear that is pivotably arranged in the trigger housing between a holding position and a release position and interacts with the trigger, and a lock catch element that is slidably arranged on the trigger housing to limit the axial movement of the chamber when opening. The trigger mechanism also has an adjustment mechanism for changing the trigger weight. However, especially with low trigger weights, the trigger mechanism requires increased care when operating.

The object of the invention is to create a trigger device of the type mentioned at the outset, which enables improved safety against the accidental discharge of a shot. This object is achieved by a trigger device with the features of claim 1. Useful embodiments and advantageous further developments of the invention are specified in the subclaims.

In the trigger device according to the invention, a safety device with two pendulums that can be pivoted by impacts is assigned to the trigger, which can be moved between an initial position and a release position, whereby the two pendulums are connected to the trigger in such a way that the trigger is pushed into its initial position by at least one of the two pendulums when the two pendulums are deflected due to an impact. The trigger device therefore has a shock or drop safety device that is effective in all directions and can prevent a shot from being fired accidentally in the event of impacts, vibrations or the like. The force exerted on the trigger by the two pendulums when they are deflected increases the force required to operate the trigger. The greater the impact effects on the trigger device or the handgun, the more The trigger resistance is increased to prevent accidental discharge. This further improves safety.

In a practical embodiment, the two pendulums arranged in a trigger housing so as to pivot about a transverse axis are designed as eccentrically mounted mass bodies whose center of mass is offset upwards relative to the transverse axis and forwards when viewed in the direction of fire.

The two pendulums can be arranged in a structurally advantageous and space-saving design so that they can rotate about a common axis of rotation via a cross hole and a cross pin. The two pendulums can also have separate axes of rotation. The two pendulums have the same basic shape, but can also be designed differently.

One pendulum can contain, on its rear end face as seen in the firing direction, a first pressure element offset from the transverse axis in a first direction for engaging the trigger and a first spring for pressing the first pressure element against the trigger, and the second pendulum can contain, on its rear end face as seen in the firing direction, a second pressure element offset from the transverse axis in a second direction opposite to the first direction and a second spring for pressing the second pressure element against the trigger.

The two pendulums can contain on their rear face an upper blind hole arranged above the axis of rotation and a lower blind hole arranged below the axis of rotation, in each of which a spring and a pressure element are arranged.

Conveniently, the two springs and the two pressure elements of the first and second pendulums rest on an upwardly projecting part of a trigger blade carrier which can be rotated about a cross pin.

The pressure elements are preferably made of rubber or a similar elastic material. However, they can also be made of another material.

The transmission element arranged between the trigger and the sear can be designed in the form of a rotatable rocker with a first arm that interacts with the trigger and a second arm that interacts with the sear. A first catch for engagement with a first counter catch on the trigger is preferably arranged on the first arm of the transmission element and a second catch for engagement with a second counter catch on the sear is arranged on the second arm of the transmission element.

Figure 1 shows a part of a repeating rifle that contains a bolt lock with an axially movable chamber 1 and a trigger mechanism 2. The chamber 1 contains a cylindrical chamber body 4 that can be moved axially within a bolt housing by means of a bolt handle 3 and can be rotated about the central axis between a locking position and an unlocking position, and a lock 5 arranged at its rear end. At the front end of the cylindrical chamber body 4, several locking lugs 6 are provided in a manner known per se for locking the chamber 1 in the bolt housing, a system sleeve or in a barrel. An axial guide groove 7 is arranged on the outside of the cylindrical chamber body 4.

In the chamber body 4 and the lock 5 of the chamber 1 are a Figure 2 shown firing pin 8 and a firing pin spring 9 arranged coaxially around the firing pin 8 are guided axially displaceably. A cocking slide 10 which can be operated by the thumb is arranged on the lock 5 of the chamber 1 for cocking the firing pin spring 9. A firing pin nut 11 which is guided axially displaceably within the lock 5 is fastened to the rear end of the firing pin 8.

The also in Figure 3 The trigger device 2 shown in an exploded view contains a trigger 14 which can be pivoted about a first transverse pin 13 within a trigger housing 12 and which, in the embodiment shown, consists of a trigger carrier 15 which can be rotated about the first transverse pin 13 and a trigger 16 which is detachably attached to the underside of the trigger carrier 15. A trigger guard 17 is attached to the underside of the trigger housing 12. The Trigger device 2 also contains a trigger lug 19 which is pivotally mounted in the trigger housing 12 about a second transverse pin 18 and which has a Figure 2 identifiable sear catch 20 for engagement with a locking edge 21 of the firing pin nut 11. Via a Figure 3 The spring 22 shown presses the sear 19 upwards in the direction of the firing pin nut 11 into a cocking position.

So that the sear 19 can move from its upper cocking position for holding the firing pin nut 11 into a lower firing position for releasing the firing pin nut 11 by actuating the trigger 14, a rocker-shaped transmission element 24 that can pivot about a third cross pin 23 within the trigger housing 12 is provided between the trigger 14 and the sear 19. The rocker-shaped transmission element 24 can be moved between a holding position for holding the sear 19 in the cocking position and a release position for moving the sear 19 into the firing position.

Out of Figure 1 It can be seen that a fork-shaped lock catch element 25 is arranged on the trigger housing 12 and can be moved transversely to the chamber 1. The lock catch element 25 is Figure 3 The chamber body 4 is pushed upwards by the compression springs 26 shown in FIG. 1 and has a pin 27 on its upper side for engagement in the guide groove 7 on the outside of the chamber body 4. The lowering of the Figure 4 The lock catch element 25 shown can be operated by an adjusting slide 29 which is slidably guided in a guide groove 28 on the side of the trigger housing 12 via a lever 30 which is rotatably mounted on the trigger housing 1. The lever 30 is designed as a double-arm lever which can be pivoted centrally about a pivot pin 31, so that the lock catch element 25 can be lowered by lifting the adjusting slide 29 in order to dismantle the chamber 1.

As from Figure 3 As can be seen, two pendulums 34 and 35 which can be pivoted about a transverse axis 33 by a transverse pin 48 are arranged in a recess 32 on the upper side of the trigger housing 12. These pendulums 34 and 35 form part of a shock or fall protection device, which is explained in more detail below.

The trigger 14 is between a Figure 2 shown starting position and a retracted release position. By means of a Figures 2 and 3 The trigger 14 is pressed into the starting position via a pressure pin 37 by the trigger spring 36 shown. In the embodiment shown, the trigger spring 36, which is designed as a spiral compression spring, is located within a longitudinal bore running through the trigger housing 1 in the longitudinal direction thereof and is clamped between the pressure pin 37 and a spring bolt 38, which rests against a bolt-shaped adjusting element 39 arranged in the trigger housing 12 for changing the trigger weight. The bolt-shaped adjusting element 39 is provided with a plurality of adjusting surfaces distributed in the circumferential direction for changing the preload force of the trigger spring 36.

In the Figures 4 and 5 it can be seen that the rocker-shaped transmission element 24, which can be rotated about the third transverse pin 23, has a first arm 40 which projects forwards as seen in the firing direction, and a second arm 42 which projects upwards and engages in a recess 41 in the sear 19. At the front end of the first arm 40 which projects forwards, a lower first catch 43 is provided for engaging with a first counter catch 44 on the trigger 14. The first counter catch 44 is arranged on an upwardly projecting part 47 of the trigger carrier 15 which can be pivoted about the transverse axis 13. At the upwardly projecting second arm 42 of the rocker-shaped transmission element 24 which can be rotated about the transverse axis 23, an upper second catch 45 is provided for engaging with a second counter catch 46 which projects forwards in the recess 41 in the sear 19. The second catch 45 on the second arm 42 of the transmission element 24 and the counter catch 46 in the recess 41 of the sear 19 are designed in such a way that the sear 19, which can be pivoted about the cross pin 18, can move downwards into a firing position by rotating the transmission element 24 counterclockwise.

The two in the trigger housing 12 by a cross pin 48 pivotally mounted about the transverse axis 33 and in Figure 7 The pendulums 34 and 35, which are shown separately in a rear view, each have a transverse bore 49 for receiving the transverse pin 48. The two angular pendulums 34 and 35 are designed as eccentrically mounted inertia bodies in such a way that their center of mass is offset upwards relative to the transverse axis 33 and forwards when viewed in the direction of fire. As a result, the pendulums 34 and 35 perform a pivoting movement about the transverse axis 33 when impacted on the trigger housing 12. On their rear end faces 50, which are at the rear when viewed in the direction of fire and face the upper part 47 of the trigger carrier 15, the pendulums 34 and 35 each have an upper blind hole 51 arranged above the transverse bore 49 and a lower blind hole 52 arranged below the transverse bore 49. In the upper blind hole 51 of the In the left pendulum 34, as seen in the firing direction, there is a first spring 53 for contact with the upper part 47 of the tongue carrier 15, and in the lower blind hole 52 of the left pendulum 34, as seen in the firing direction, there is a first pressure element 54, here in the shape of a pin, for contact with the upper part 47 of the tongue carrier 15. In the upper blind hole 51 of the right pendulum 35, as seen in the firing direction, there is a second pressure element 54, here in the shape of a pin, for contact with the upper part 47 of the tongue carrier 15, and in the lower blind hole 52 of the right pendulum 35, as seen in the firing direction, there is a second compression spring 53 for contact with the upper part 47 of the tongue carrier 15. The two pressure elements 54 are designed in the manner of a buffer, e.g. made of rubber or another elastically flexible material. The shock pulses acting between the pendulums 34 and 35 and the trigger 14 can be dampened via the buffer-like pressure elements 54. The two compression springs 53 press the pendulums 34 and 35 onto the upper part 47 of the trigger carrier 15 via the buffer-like pressure elements 54.

Due to the design and arrangement of the two pendulums 34 and 35 described above, they act as an inertial mass and, when the trigger housing 12 is impacted, they pivot about the transverse axis 33. Due to the different arrangement of the compression springs 53 and pressure elements 54 between the two pendulums 34 and 35 and the trigger 14, they act as a multidirectional fall or shock protection device, the functioning of which is explained below using the Figures 8 to 11 is explained.

In the Figure 8 the trigger device 2 is shown in a cocked position. The rocker-shaped transmission element 24 rests with its front first catch 43 on the first counter catch 44 at the upper end of the upwardly projecting part 47 of the trigger carrier 15. In this position of the rocker-shaped transmission element 24, the rear second catch 45 of the rocker-shaped transmission element 24 engages under the second counter catch 46 on the sear 19, so that the sear 19 is held in the upper holding position. In this upper holding position, the Figures 1 and 2 shown firing pin nut 11 is held by the sear catch 20. The two pendulums 34 and 35 are in a non-deflected starting position and are pressed by the compression springs 53 with their pressure elements 54 onto the blade carrier 15 of the trigger 14 above the cross pin 13 serving as the axis of rotation for the trigger 14.

In Figure 9 the trigger mechanism 2 is shown with the trigger 14 released. By pulling back the tongue 16, the first counter-latch 44 at the upper end of the tongue carrier 15 releases the front first latch 43 on the transmission element 24, so that the transmission element 24 can rotate anti-clockwise and the front first arm 40 can move downwards. The second latch 45 on the second arm 42 of the transmission element 24 disengages from the second counter-latch 46 on the sear 19, so that the sear 19 can rotate into the lower firing position to release the firing pin 8 acted upon by the firing pin spring 9. The movement of the upwardly projecting part 47 of the tongue carrier 15 causes the two pendulums 34 and 35 to move in opposite directions.

When the trigger mechanism 2 is in the cocked position according to Figure 10 a blow in the direction of arrow 55 caused e.g. by falling or by impact on the butt plate of the repeating rifle or a shock from above in the direction of arrow 56, ie a shock acts on the repeating rifle from behind or above, the two pendulums 34 and 35 deflect in a clockwise direction, whereby the right pendulum 35, seen in the direction of fire, presses with its pressure element 54 against the upper part 47 of the trigger carrier 15 and holds the trigger 13 in its starting position.

On the other hand, if the trigger mechanism 2 is in the cocked position according to Figure 11 a shock in the direction of the two arrows 57 and 58, ie a shock from below or from the front, deflects the two pendulums 34 and 35 in an anti-clockwise direction, deflects the right pendulum 35 as seen in the direction of fire, whereby the left pendulum 34 as seen in the direction of fire presses with its pressure element 54 against the upper part 47 of the trigger carrier 15 and holds the trigger 13 in its starting position. As a result, a force is exerted on the trigger 13 via the two pendulums 34 and 35 in the event of shocks in all directions, which presses the trigger 13 into its starting position.

In addition to the fall and shock protection described above, the trigger mechanism 2 also provides a Figures 12 to 14 The safety mechanism shown in more detail to prevent unwanted firing when the chamber 1 is unlocked can be reached. For this purpose, the lock catch element 25, which is arranged on the upper side of the bolt housing 12 and is displaceable transversely to the chamber 1, has a Figures 12 and 13 shown, here pin-shaped locking element 59, which is in two in Figure 3 visible cross holes 60 in the two Side cheeks of the fork-shaped lock catch element 25 and cooperates with the forward-projecting arm 40 of the rocker-shaped transmission element 24 to block or release the trigger 14. The transmission element 24 contains a semicircular recess 61 in one of the two side cheeks, into which the rounded first end of the lever pivotable about the pivot pin 31 engages. The other rounded second end of the lever 30 engages in a semicircular recess 62 on the adjusting slide 29.

In Figure 14 it can be seen that on the chamber body 4 of the chamber 1, which can be rotated about a longitudinal axis 63 between a locking position and an unlocking position by means of the bolt handle 3, a control curve 64 designed as a radial groove on the outside of the chamber body 4 is provided for moving the lock catch element 25 from a lowered unlocking position into a raised locking position when the chamber body 4 is rotated into the unlocking position by raising the bolt handle 3. The control curve 64 has a first control surface 65, against which the upper pin 27 of the lock catch element 25, which is pressed upwards by the compression springs 26, comes to rest when the chamber body 6 is in a locked position and by which the lock catch element 25 is pressed into the unlocking position. The control cam 64 also has a second control surface 66 which follows the first control surface 65 in the circumferential direction of the chamber body 6 and is set back from it, against which the upper pin 27 of the lock catch element 25 pressed upwards by the compression springs 26 comes to rest when the chamber body 6 is unlocked and through which the lock catch element 25 comes into the raised securing position.

In the Figure 14 In the locking position of the chamber 1 shown, the lock catch element 25, which is pushed upwards by the two compression springs 26, rests with its upper pin 27 on the first control surface 65 and is pushed downwards by this into the Figure 12 shown release position. In the release position, the pin-shaped locking element 59 is spaced from the underside of the forward-projecting leg 40 of the rocker-shaped transmission element 24, so that the rocker-shaped transmission element 24 can rotate anti-clockwise when the trigger 14 is actuated and the firing pin nut 11 arranged at the end of the firing pin 8 can be released via the sear catch 20 to fire the firing pin 8.

If, however, the bolt handle 3 is Figure 14 shown locking position for unlocking the chamber 1 and thereby the chamber body 4 is rotated counterclockwise as seen in the firing direction, the pin 27 on the upper side of the lock catch element 25 reaches the second control surface 66 of the control cam 64, which is offset inwards relative to the first control surface 65, so that the lock catch element 25 can move upwards into the raised safety position under the action of the springs 26.

In the completely unlocked position of the chamber 1, the pin 27 enters the longitudinal groove 7 of the chamber body 4, so that the chamber 1 can be pulled back to open the chamber lock. The groove 7 has a Figure 1 visible stop surface 67 for the pin 27 of the lock catch element 25 to rest on. This can prevent the chamber 1 from being completely pulled out of the chamber sleeve during repetition. To disassemble the chamber 1, the lock catch element 25 can be moved into a lowered disassembly position by the adjusting slide 29 via the lever 30.
