Description

Technical field

[0001] The present invention relates to a trigger system for firearms. The trigger system is intended to improve the precision, safety and adaptability of the firearm during operation.

[0002] In this application, firearms include in particular short and long guns, especially pistols and rifles, in particular assault rifles and precision rifles.

[0003] Positional terms such as "above", "below", "left", "right", "front", "back", etc. refer in this application to a firearm held in a normal shooting position, in which the bore axis runs horizontally and the shot is fired forward away from the shooter. State of the art

[0004] For firearms, especially assault rifles, a reliable and efficient trigger system that ensures proper firing is essential. In particular, the trigger pull required to fire, also known as trigger resistance or trigger weight, can significantly influence the shot and its outcome. Excessive trigger resistance can lead to inaccurate shots, for example, because the increased force required causes the weapon to jerk. However, insufficient trigger resistance can also negatively impact accuracy, for example, due to inadequate tactile feedback to the shooter, and can also pose a safety risk, such as unintentional or premature firing.

[0005] Different trigger characteristics have proven effective for different operational and training scenarios. In some situations, pulling the trigger all the way through without a clear pressure point leads to better results.

[0006] However, many shooters, especially in situations requiring precise shooting, desire a point along the trigger travel where the shot breaks as precisely as possible, and one whose intensity is adjustable, particularly through feel. For this purpose, two-stage triggers are used, also known as pressure-point, two-point, or match triggers. With such a pressure-point trigger, a pressure point is felt when pulling the trigger blade, signaling to the shooter the imminent release of the shot. Up to this pressure point, along the so-called take-up travel, the shooter works against the so-called take-up force when pulling the trigger. Once the pressure point is reached, the higher release force must be overcome to continue the pull. From this point onward, the pull force must be increased.

[0007] The entire trigger travel, i.e. the path along which the trigger blade must be pulled to release the fire, consists of two sections in a pressure point trigger system, characterized by different trigger forces: a first section characterized by the pre-travel force (also called pre-travel) and a second section characterized by the release force (also called release travel).

[0008] Ideally, a trigger system, whether a direct trigger or a two-stage trigger, should be as freely adjustable as possible. This allows the trigger pull to be varied depending on the shooting situation and personal preference. In conventional trigger systems, the trigger pull is primarily influenced by the force of the hammer spring. This spring is cocked when the hammer is cocked, providing the necessary energy to release the shot. In classic trigger systems, the cocked hammer is initially held in place by a releasable detent mechanism. The hammer and trigger system have corresponding detents for this purpose. To fire the shot, this detent must be released, or the detent mechanism must be separated. This requires overcoming, for example, a resulting frictional force that is directly dependent on the force of the hammer spring.Since the hammer must possess relatively high energy to ignite the cartridge's propellant and reliably trigger a shot, springs with comparatively high spring constants are typically used, which can result in a relatively high frictional force to overcome. This can lead to a high trigger pull and limit the trigger's adjustability.

[0009] Furthermore, it is important to prevent unintentional discharges due to inadequate safety mechanisms or accidental trigger pulls. Accordingly, trigger systems should interfere with existing safety mechanisms as little as possible.

[0010] Known solutions use adjusting screws to set the trigger pull weight and built-in safety mechanisms that block movement when the trigger is pulled. However, these solutions have their limitations, such as the risk of the adjusting screws loosening and the safety mechanisms failing.

[0011] German patent DE 19626077 C2 discloses a trigger mechanism for a self-loading firearm with a switch to automatic fire. It comprises a hammer, a bolt, a sear, a pivotally mounted trigger, and a lever that engages the hammer after each shot and keeps it cocked when switching to automatic fire. This design offers a two-stage trigger with a large trigger / sear contact area and an optimized sear bearing angle to enable a smooth trigger pull. It also features a safety mechanism that blocks the trigger movement.

[0012] US 20180149441 A1 proposes a two-stage trigger mechanism for automatic weapons, comprising spring-loaded links, hammer, and breaker. Calibrated springs allow for adjustable trigger pull weight in the second stage without the need for adjusting screws, thus preventing accidental firing of the weapon during hand assembly.

[0013] DE 202023002425 U1 provides a trigger mechanism for quick installation and removal in AR-3 type firearms. It consists of a trigger housing with two hollow shafts, a hammer and a tongue, as well as two bearing pins connected by a threaded spindle.

[0014] US 7600338 B2 describes a trigger with step-adjustable weight for AR-style firearms. The trigger assembly consists of a spring-loaded firing pin, a trigger, and a breaker. Calibrated springs are provided to facilitate adjustment of the second trigger pull weight.

[0015] Despite these state-of-the-art solutions, there is a need for a trigger system that offers improved adjustability, especially of the trigger dynamics. Problem and solution of the invention

[0016] The object of the present invention is to provide alternative, adjustable trigger systems.

[0017] The invention solves this problem with the subject matter of the independent claims. These and further exemplary embodiments are evident from the dependent claims and the following description.

[0018] One aspect of the invention (claim 1) relates to a trigger system for firearms, in particular assault rifles. This trigger system has a hammer that can be moved from a relaxed position to a cocked position to generate the necessary firing energy. The trigger system further comprises a first system element that is movable back and forth between a first position and a second position. In the first position, the engagement position, the first system element and the hammer, in its cocked position, are engaged in a releasable manner. In the second position, the separation position, the first system element is separated from the hammer. The trigger system also has a second system element that is movable back and forth between a third position and a fourth position. In the third position, the blocking position, the second system element blocks the first system element against movement from the engagement position toward the separation position.In the fourth position, the release position, this blockage is lifted, allowing the first system element to move freely from its engaged position to its disengaged position and vice versa. The cock is locked in its cocked position when the first system element is in the engaged position and the second system element is in the blocking position. By pulling a trigger lever connected to the second system element, the second system element is moved from its blocking position, in which it blocks the first system element, to its release position, in which it no longer blocks the first system element, or rather, this blockage is lifted.Once the second system element has been moved into its release position, the hammer, due to the impact energy built up in it by cocking, first pushes the first system element into the separation position, which separates the hammer and the first system element, and then strikes completely into its relaxed position to fire a shot.

[0019] The hammer, also known as a striker or firing pin, is a common component in long guns and handguns. It is designed to be cocked, from which it then strikes the firearm. When the hammer is cocked, a hammer spring is compressed, storing the (potential) energy generated during cocking in the spring. Upon firing, i.e., when the spring automatically releases after a trigger mechanism is activated, this energy is completely converted – first into kinetic energy during the firing motion and then into the heat necessary to ignite the cartridge.

[0020] The first system element acts as an intermediary or transmission element between the valve and the second system element, which will be described in more detail later. Specifically, it can transmit a blocking effect from the second system element to the valve, so that, for example, the valve is indirectly held or locked by the second system element. In other words, the first and second system elements work together to hold or lock the valve in its cocked position. The first system element can be designed, for example, as a bracket or lever, and, due to its locking effect on the valve, can be referred to as a locking lever or bracket.

[0021] The first system element is movably mounted so that it can be moved back and forth between its engagement and separation positions.

[0022] In the engaged position, the first system element, along with the tap, enters a releasable engagement as soon as the tap is cocked, i.e., brought into its cocked position. In some embodiments, described later, the first system element and, if applicable, the tap also have correspondingly designed locking devices. In these embodiments, the releasable engagement can be effected via these locking devices. For example, a first locking device is arranged on the tap and a second locking device is arranged on the first system element. Regardless of the specific embodiment, the second system element is able to block the first system element in such a way that the latter cannot easily leave its engaged position. In this case, the tap is locked in its cocked position until the blockage is released by the second system element.The engagement position of the first system element thus holds the valve in its cocked position until the blockage is released by the second system element. This engagement position is therefore also referred to as the valve-holding position. This will be described in more detail later.

[0023] In the disconnected position of the first system element, the valve and the first system element are separated in such a way that they cannot engage. In embodiments where special locking devices are provided for engagement, these residual devices, for example, cannot engage in the disconnected position. Therefore, in this position of the first system element, the valve can move freely from its cocked position to the relaxed position. The disconnected position of the first system element is thus also referred to as the valve-releasing position.

[0024] The movement performed by the first system element when moving from one position to another can be a translational or a rotational movement.

[0025] In certain embodiments, the first system element can be moved along a substantially linear path between the engagement and separation positions for a translational movement. This path can be entirely or partially straight. Additionally or alternatively, the path can have curved sections.

[0026] For translational movement, the first system element can, for example, have a groove or recess that accommodates one or more springs (in the sense of a tongue-and-groove connection), tenons, or pins. In this case, the groove, or its path, defines the movement path of the first system element between its engagement and disengagement positions. However, the reverse case is also possible, in which the first system element has one or more springs, tenons, or pins that are accommodated by a groove defining the movement path. This groove can, for example, be located on an additional system element.

[0027] In other preferred embodiments, the first system element performs a rotational movement between its engagement and separation positions. It thus moves along a circular path or at least along a circular segment to switch between the engagement and separation positions. For this purpose, it can be rotatably mounted, e.g., about a pivot point, particularly an axis. For example, this pivot point is located centrally or in a region around the center of the first system element.

[0028] The second system element can be any component suitable for blocking the first system element. Depending on the specific design, the expert will use familiar means for this selection, e.g., a locking bolt, a stop, a detent, or a latch.

[0029] The second system element can come into physical contact with the first system element, for example, by touching it, in order to block it. As already described, when blocked by the second system element, the first system element is held in its engaged position and cannot easily leave this position. The blockage of the first system element can be achieved, for example, by the second system element positioning it behind the first. This blockage prevents, for instance, a rotation or translation of the first system element that would allow it to move into its separation position.

[0030] The second system element is coupled to the trigger either directly or indirectly, for example via other elements. The second system element can be, for instance, a single unit with the trigger, or the second system element and trigger can be two separate but coupled parts. Alternatively, the second system element can be coupled to the trigger via several other components. The coupling of the second system element to the trigger is designed such that pulling the trigger also results in a movement of the second system element from its locked position towards its unlocked position, i.e., from its position blocking the first system element to the position that releases this blockage. For this purpose, the trigger and second system element can be rigidly coupled or connected, so that a movement of the trigger is directly transmitted to the second system element.However, a coupling that indirectly transmits the trigger's movement is also possible. In either case, pulling the trigger or fully releasing it moves the second system element from its locked position to its unlocked position. The lock caused by the second system element can therefore be released by pulling the trigger, for example, by pulling the trigger. For instance, in its unlocked position, the second system element is outside the path of any rotational or translational movement of the first system element. The rotation or translation of the first system element is then no longer prevented by the second system element, or is possible without further ado.

[0031] Once the second system element is released from its blocking position, the first system element moves independently into its cock-release position. The first system element can be spring-loaded, for example, directly or indirectly. The force of the cock spring can be used to move the first system element. For instance, the cock, or a first locking device attached to the cock, and the first system element, or a second locking device attached to the first system element, can be arranged such that a force generated by the tensioned cock spring and acting on the cock is transferred from the cock to the first system element. This spring force then moves the first system element, which is not blocked by the second system element, into its release position, in particular by forcing it.

[0032] To transmit force from the tap to the first system element, the first system element can have a contact surface through which it engages with the tap in its engaged position. Additionally, the tap can also have a corresponding contact surface so that both contact surfaces come into contact, e.g., touching, during engagement. For example, the surface on the tap (or its normal vector) can point upwards and be pressed from below by the tap spring against the surface of the first system element, which has its normal vector pointing downwards. In this case, the surfaces are arranged such that their two normal vectors are antiparallel to each other and the surfaces at least partially overlap.

[0033] Regardless of whether the tap has a contact surface (e.g., direct or indirect) or not, the tap can transfer the spring force acting on it to the contact surface of the first system element in such a way that this force, or at least a component thereof, forces the first system element into its tap-releasing separation position.

[0034] Overall, this aspect of the invention has the advantage, among others, that the blocking effect of the second system element can be transferred to a section of the tap that is as far away as possible from the pivot axis of the tap by means of the first system element acting as an intermediary. According to the lever principle, this reduces the force required to release the tap from its cocked position in proportion to the distance to the pivot axis or pivot point of the tap (tap axis or tap pivot point).

[0035] According to one embodiment (claim 2), the required deceleration energy is generated by a tap spring acting on the tap, in particular a torsion spring. Such tap springs are familiar to those skilled in the art and have the advantage that, as proven methods, they do not require any design changes.

[0036] According to a further embodiment (claim 3), the second system element, in its blocking position, blocks the first system element by means of a backstop. Backstop is a proven and reliable method for blocking a movable element. Advantageously, the person skilled in the art can use established means such as locking bolts, abutments, detents, or latches.

[0037] According to a further embodiment (claim 4), the valve can have a first locking means and the first system element can have a second locking means which can be releasably engaged with the first locking means. In this case, the releasable engagement of the cocked valve with the first system element in its engaged position, as already described, can be effected via the first and the second locking means.

[0038] According to a further embodiment (claim 5), the first system element is pivotably mounted about a pivot point or pivot axis such that it can pivot between its engagement position and its disengagement position. For example, the pivotable mounting can be located in an area near the center of the first system element. Preferably, it is located in the center of the first system element. For example, the pivotable mounting can be implemented by a pivot axis, so that the first system element can rotate about this axis. The first system element can, for example, have a hole that receives / guides the pivot axis. However, the pivot axis can also be rigidly connected to the first system element and mounted in one or two axle bearings not belonging to the first system element, so that the first system element, including the pivot axis, is rotatably or pivotably mounted in the bearings.

[0039] Alternatively, or additionally, the first system element can be mounted in a slidable manner, such that it can be moved between its engagement position and its separation position.

[0040] According to a further embodiment (claim 6), for example, the second locking element of the first system element has a first contact surface that contacts the first locking element of the valve when the first system element is in the engaged position and the valve is in the cocked position. The first contact surface is designed such that its normal vector forms an angle α, in particular less than or equal to 90° and greater than 0°, with an imaginary line connecting the first contact surface to the pivot point of the first system element, so that a force component resulting from a force transmitted by the valve and acting along the normal vector acts perpendicular to the connecting line, i.e., in a direction tangential to the circular motion. This tangential force component pushes the first system element in the direction of its disengagement position. The first contact surface on the first system element can be arranged on the second locking element of the first system element.Another optional contact surface on the tap side can be arranged on the first locking device of the tap.

[0041] The first locking element transfers at least a portion of the force acting on the valve to the second locking element. When the first and second locking elements make contact at the first contact surface, the force transferred from the valve to the second locking element acts along the normal vector of the first contact surface. This force can be used, for example, to pivot the first system element around a pivot point; for instance, from its engaged to its disengaged position. For this to occur, the force acting along the normal vector of the first contact surface must have a non-zero component capable of forcing the first system element from its engaged to its disengaged position, or generating a corresponding non-zero torque on the first system element.The normal vector of the first contact surface must therefore not point along the aforementioned connecting line from the first contact surface to the pivot point of the first system element (radial direction), as this would not result in a torque. Instead, the first contact surface must have a suitable inclination relative to the imaginary connecting line between the contact surface and the pivot point. This inclination must be such that the force acting along the normal vector results in a non-zero tangential component. In other words, the force acting along the normal vector must result in a force component acting orthogonally to the aforementioned imaginary connecting line. This force component causes the first system element to move from the engaged position to the disengaged position.

[0042] The pivotable mounting of the first system element has the advantage that only the tangential component of the force acting along the normal vector contributes to the perceptible trigger pull. Only this component is transmitted by the pivotable mounting to the contacting areas of the first and second system elements and contributes to the frictional force that must be overcome when pulling the trigger. Since the tangential component is a fraction of the normal force, the trigger pull can be further reduced. The frictional force must be overcome at a minimum during trigger pull and therefore determines the lower limit of the trigger pull. The lower limit of the trigger pull can therefore be lowered by means of the invention. In particular, the trigger pull can be reduced below the force range preferred by shooters and can therefore be adjusted to the desired level by means of additional means, e.g., springs. The lower adjustability is thus improved.

[0043] If the first contact surface forms an angle with the imaginary connecting line that lies between 90° inclusive (normal vector orthogonal to the connecting line) and 0° inclusive (normal vector parallel to the connecting line), this advantageously results in a force component that points in the tangential direction and thus forces the first system element into the separating position. This ensures that the first system element is automatically forced into the valve-releasing position by the valve itself. The angle is preferably greater than 0° and less than 90°, particularly between 10° and 80°, particularly between 20° and 60°, particularly between 20° and 45°, and most preferably between 25° and 30°.

[0044] According to one embodiment (claim 7), the second locking device is a pawl. The pawl is pivotally mounted such that it allows the first locking device to pass unimpeded when the first system element is in its engaged position and the valve is moved into the cocked position. The second system element is, for example, a stop.

[0045] The detent can be pivotally mounted around a pivot point, in particular an axis. The detent can thus be pivoted, for example, between a first and a second detent position.

[0046] In the first detent position, the first and second detent elements engage as soon as the hammer is cocked and the first system element is in its engaged position. When the first system element is in its engaged position and the detent pawl is in its first detent position, the first detent element and the detent pawl engage when the hammer is moved towards its relaxed position. If the second system element then blocks the first, the hammer is held or locked in the cocked position.

[0047] In the second detent position, the tap, or rather the first detent element of the tap, can pass the detent essentially unimpeded during cocking, even when the first system element is in its engaged position. For example, during cocking, i.e., during the cocking movement from the relaxed tap position to the cocked tap position, the detent element pushes the detent from its first detent position to its second detent position. The first detent element thus pushes the detent aside so that it can pass unimpeded, even when the first system element is in its engaged position. While the first detent element and the detent are in contact, the detent allows the first detent element to pass. Once the first detent element has passed the detent, the latter then moves independently from its second detent position back to its first detent position.For example, it is spring-loaded so that a spring pushes the pawl from its first pawl position to its second pawl position.

[0048] According to one embodiment (claim 8), the cock is pivotably mounted about a cock pivot point and is pivoted about this pivot point to move it from the relaxed position to the cocked position. Furthermore, the end of the cock facing the first system element is elongated or U-shaped. In addition, the two locking means are arranged such that the releasable engagement occurs in an end region of the cock distal to the cock pivot point. Finally, the second system element is arranged such that the blocking of the first system element occurs in a trigger-side region of the first system element, i.e., in a region which, from the perspective of the first system element, lies on the trigger side.

[0049] For example, the first system element can have two arms extending from its pivot point. One arm extends towards an area near the cock, so that the cock and the first system element can engage as soon as the first system element is in its engaged position. In particular, if the second locking element is located at the cock-side end of the first system element, it can engage with the first locking element located on the cock. The other arm, however, can extend to an area near the trigger. In this case, the second system element is also located in this area near the trigger, so that the second system element can block the first at its trigger-side end.

[0050] The engagement of the two locking mechanisms occurs in an end region of the tap distal to the tap pivot point, i.e., in a region of the tap located around the end furthest from the tap pivot point. This means that less force is required to hold the tap in its cocked position than with an engagement in an end region proximal to the tap pivot point (lever principle).

[0051] According to one embodiment (claim 9), the trigger system further comprises a return spring which forces the first system element from its separating position into its engagement position.

[0052] This return spring can, for example, be located on the hammer-side of the first system element and counteract the force component that pushes the first system element into its disengaged position when the second system element is in its release position. For example, the spring constant can be chosen such that the resulting spring force is smaller than the aforementioned force component, but large enough to move the first system element into its engaged position without the opposing force component. Advantageously, this ensures that the first system element is reliably moved into the hammer-locking engaged position after firing.

[0053] According to one embodiment (claim 10), the end of the tap facing the first system element, i.e., the end distal to the tap pivot point, is wedge-shaped. The tap is dimensioned such that when the tap is moved into the cocked position, the distal end forces the first system element into its engagement position. This advantageously results in a forced return of the first system element.

[0054] For example, the aforementioned hammer end is designed in a scoop shape. The position of the hammer and / or its length relative to the first system element in its disengagement position can be chosen such that, when the hammer is cocked, the tip of the wedge- or scoop-shaped hammer end moves behind the hammer-side end of the first system element, and the latter is forced towards its engagement position due to the wedge or scoop shape. This has the advantage that, when the hammer is cocked, the first system element is reliably brought into the engagement position, thus ensuring the hammer is locked after cocking. This prevents, for example, an unintentional discharge. This represents an additional safety measure that also ensures the first system element is reliably brought into its engagement position even if the previously described return spring fails after firing.This is particularly advantageous with automatic weapons, where the hammer is automatically moved into its cocked position after the shot is fired.

[0055] The position of the hammer can be adjustable. For example, a hammer shaft can be arranged in a horizontally extending slot. Within this slot, the hammer shaft can be moved horizontally and locked in the desired position. This ensures, among other things, that the wedge-shaped distal end of the hammer is moved behind the first system element when the hammer is cocked. Furthermore, this allows different hammers to be used while maintaining the same trigger mechanism. For instance, different rifles can use differently designed hammers but share the same overall trigger mechanism. By using a slot, the position of the hammer shaft can be adjusted to the specific hammer being used. For example, if a drop-in receiver is used, the receiver can be mounted first, and then the hammer can be detached and positioned accordingly using the slot.in which the tap axis is positioned appropriately along the elongated hole.

[0056] According to one embodiment (claim 11), the trigger system comprises a first trigger spring. The first trigger spring is permanently coupled to the trigger blade along the entire trigger travel, so that its spring force additionally counteracts the pulling of the trigger blade along the entire trigger travel.

[0057] Advantageously, different trigger profiles can be easily set. The first trigger spring ensures a constant, consistent trigger pull.

[0058] According to one embodiment (claim 12), the trigger system comprises a second trigger spring and an adjusting element. The second trigger spring can be adjusted to couple with the trigger blade, and when coupled, the second trigger spring additionally counteracts the pulling of the trigger blade with its spring force. Furthermore, the arrangement or length of the second trigger spring can be adjusted by means of the adjusting element such that the second trigger spring couples with the trigger blade at the beginning of the trigger travel, between the beginning and end of the trigger travel, or at no point along the trigger travel.

[0059] For example, the second trigger spring can be a compression spring, and the distance between its end near the trigger blade and a coupling point with the trigger blade can be adjustable. For example, the distance can be chosen so that the second trigger spring couples with the trigger blade from the beginning of the trigger travel (distance equal to zero), or only at a selected position along the trigger travel (distance greater than zero, but less than the trigger travel), or not at all (distance greater than the trigger travel).

[0060] In this way, for example, it is possible to adjust whether the spring force of the second trigger spring counteracts the pulling of the trigger blade either along the entire trigger travel, along a part (between the beginning and end) of the trigger travel, or not at all.

[0061] The second trigger spring can therefore be engaged in an adjustable manner. This allows switching between two different direct triggers (second trigger spring coupled to the trigger blade along the entire trigger travel or not coupled to the trigger blade at any point) and at least one two-stage trigger (second trigger spring coupled to the trigger blade from at least one adjustable position along the trigger travel). According to some embodiments, several positions between the beginning and end of the trigger travel are also adjustable, at which the coupling between the second trigger spring and the trigger blade occurs. Advantageously, several different two-stage triggers can be set, differing in the position of the perceptible pressure point along the trigger travel. The required forces (release force, pre-travel force) can be determined by a suitable selection of the trigger springs and their respective spring constants.

[0062] The trigger travel can be adjusted or predetermined, for example, via one or more stops. An optionally adjustable catch edge can also be coupled to the trigger blade and / or the second system element and move along with it during triggering. The trigger travel is then limited by the catch edge striking a fixed component (not coupled to the trigger blade) at a predetermined position. The trigger travel and trigger characteristics can be further modified by changing the catch edge.

[0063] According to one embodiment (claim 13), at least the first and second system elements are housed in a trigger housing that can be installed and removed from a firearm as a drop-in component. Drop-in housings are a familiar and simple means for quick and easy replacement of trigger groups or systems. In some embodiments, other parts of the trigger system are also housed in the drop-in housing.

[0064] According to one embodiment (claim 14), the second system element, or a contact surface provided on the second system element, or a part of the second system element comprising the contact surface provided on the second system element, is designed to be interchangeable.

[0065] For example, the second system element can be removed from the extraction system and reinstalled to replace it with a new second system element, to service or repair it, or to clean it. In some of these embodiments, only a portion of the second system element, comprising the contact surface, can be removed and reinstalled for these purposes. In some of these embodiments, only the contact surface itself can be removed and reinstalled for these purposes. In any case, the removable and reinstallable elements mentioned are easily removable and reinstallable, e.g., without tools. Advantageously, this makes maintenance, cleaning, and / or replacement easy.

[0066] According to one embodiment (claim 15), the trigger system further comprises a first hammer stop arranged on the hammer, and a second hammer stop arranged on a first element of the firearm that is not movable by movement of the trigger blade. The first and second hammer stops are arranged relative to each other such that, when the hammer moves into its cocked position, the first hammer stop abuts the second hammer stop, thus reducing the direct transfer of momentum to the trigger blade.

[0067] This is based on the observation that when the hammer recoils after firing and strikes, for example, a disconnector, an impulse is transferred to the trigger. This can be perceived as unpleasant or disruptive by the shooter. Furthermore, it can accelerate wear on the hammer and the parts against which it strikes. Therefore, the use of easily replaceable hammer stops can also reduce wear.

[0068] In some of these embodiments, the first and second hammer stops may be made of a harder material than the rest of the trigger system, for example, to reduce wear. In some other embodiments, the first and second hammer stops may be made of a softer material than the rest of the trigger system, for example, to cushion the impulse transfer or to prevent or reduce recoil. In some other embodiments, the first hammer stop may be made of a harder material and the second hammer stop of a softer material than the rest of the trigger system, or vice versa, for example, to advantageously combine the two effects mentioned.

[0069] In some of these embodiments, a first and a second tap stop are arranged on both sides of the tap.

[0070] The first element, which cannot be moved by the trigger, can be, for example, a weapon housing (the receiver of a rifle or the grip of a pistol). If a trigger housing is used, for example as a drop-in part, the first element can also be the trigger housing itself. In principle, however, the first element can be any suitable weapon part that does not move when the weapon is fired.

[0071] According to one embodiment (claim 16), the adjusting element is secured against rotation and / or loss.

[0072] In general, all adjustment elements of the weapon, and in particular the adjustment element mentioned above, can optionally be secured by frictional locking mechanisms, for example, by an overlapping locking pin with the adjustment element. Specifically, they can be secured against accidental rotation, excessive rotation, and / or loss, i.e., secured against rotation and / or loss. For example, the adjustment range can be limited (i.e., how far the adjustment element can be rotated for adjustment), and optionally, a defined frictional torque can be generated (e.g., to prevent unintentional rotation, e.g., due to vibration). In some of these embodiments, for example, a locking pin can be provided in the housing, and a threaded bolt with a groove can be provided on the adjustment element. In this example, the threaded bolt passes through the locking pin, or the groove receives the locking pin. The adjustment is then made, for example, by...By turning the threaded pin, which can be screwed in or out in this way, for example, to adjust the preload of a spring. However, the tension pin and the two ends of the groove limit how far it can be screwed in or out. The tension pin can also be positioned so that it exerts pressure on the threaded bolt, so that increased friction must be overcome to turn it. This intentionally makes the threaded bolt more difficult to turn. This is intended to prevent, for example, accidental turning or turning due to vibration or shock.

[0073] According to one embodiment (claim 17), the trigger system further comprises a buffer element arranged on a second element of the firearm that is not movable by movement of the trigger. When the trigger is not pulled, it contacts the trigger or an element movably coupled to it. The buffer element is designed and arranged on the second element in such a way as to buffer an impulse transmitted to the trigger or the element movably coupled to it, which points in the direction in which the trigger is pulled to fire the weapon.

[0074] This can improve drop safety or prevent a discharge caused by the weapon being dropped. This is based on the observation that when a weapon falls, the probability of it firing is higher if it lands on its front side, e.g., the muzzle, than if it lands on its rear side, e.g., the stock or pommel.

[0075] The second element to which the buffer element is attached can be, for example, the weapon housing (the receiver of a rifle or the grip of a pistol). If a trigger housing is used, for example, as a drop-in part, the second element can also be the trigger housing itself. In principle, however, the second element can be any suitable weapon part that does not move when the weapon is fired. The buffer element is preferably positioned so that an element of the trigger system that is coupled to the trigger blade and can move with it (e.g., a corresponding stop coupled to the trigger blade) contacts the buffer element when the trigger blade is not pulled. An impulse (e.g., generated by a shock) that points in the direction in which the trigger blade moves when the trigger is pulled can thus be absorbed by the buffer element. In this way, the buffer element reduces trigger recoil (the impulse response) in the event of excitation by a shock-like event.This reduces the risk of an unintentional discharge, for example if the weapon falls to the ground.

[0076] Preferably, the buffer element has a suitable shock-absorbing material so that the said impulse can be absorbed to such an extent that no or only a sufficiently small impulse response is generated, so that no shot is triggered.

[0079] The reference symbols used in the drawings and their meanings are listed in summary form in the list of reference symbols. Identical parts are generally marked with the same reference symbols in the illustrations. Detailed description of the figures

[0080] Fig. Figures 1a - 1d show an embodiment of the invention in side view. Fig. Figure 1a shows a trigger system 100 according to the invention with a cock 102 which is pivotable about a cock axis 104. By pivoting, the cock 102 can be moved between a cocked position 106 (see Figure 1). Fig. 1b) and one, in Fig. The cock 102 can be moved to the relaxed position 108 shown in Figure 1d. The cock 102 is spring-loaded, and a spring 110 (cock spring), designed as a torsion spring, forces the cock 102 from its cocked position 106 to its relaxed position 108. The cock 102 also has a cock detent 112. The cock detent 112 is located in an end region 114 distal to the cock axis 104 and thus near the cock end 116 distal to the cock axis 104. The distal cock end 116 is wedge- or shovel-shaped.

[0081] The trigger system 100 also features a first system element 122 designed as a locking lever, which is pivotably mounted about a pivot point 124 designed as an axis. The locking lever 122 can be pivoted between an engagement position 126 (e.g., Fig. 1b) and one, in Fig. The locking lever 122 is pivoted to the separating position 128 shown in Figure 1d. It has a second locking element 130 designed as a detent pawl, which pivots about a detent pawl pivot point 132 (see Figure 1d). Fig. 1b) is pivotably mounted. The locking pawl 130 can be set between a first locking pawl position 134 (szB Fig. 1b) and a second one, in Fig. The locking pawl 130 can be pivoted to position 136 shown in Figure 2. The locking pawl 130 has a first contact surface 142 at the hammer-side end 138 of the locking lever 122. Furthermore, the locking lever 122 has a return spring 146 at its end 138 facing the hammer 102. At the opposite, trigger-side end 140, the locking lever 122 has a second, trigger-side contact surface 144 (see enlargement).

[0082] The trigger system 100 also has a trigger blade 160, which is arranged around a trigger axis 162 (szB Fig. 1b) is pivotable. The trigger blade 160 is coupled to a second system element 164 designed as a locking bolt in such a way that a movement of the trigger blade 160 is transmitted to the locking bolt 164. The locking bolt 164 can be moved between a blocking position 166 (see below). Fig. 1a) and one, in Fig. The release position 168 shown in 1d is moved back and forth. In addition, the locking bolt 164 has a locking bolt contact surface 170 (see enlargement) which touches the second contact surface 144 of the locking lever 122 for blocking.

[0083] Finally, the trigger system 100 has a breaker 190 familiar to the expert, which is spring-loaded via a breaker spring 192.

[0084] With the trigger 160 not pulled, the locking bolt 164 assumes the blocking position 166. If the locking lever 122 is in the engaged position 126 and the locking bolt 164 is in the blocking position 166, the locking bolt 164 acts as a counterweight for the locking lever 122 and prevents the locking lever 122 from moving into the disengagement position 128. The locking bolt 164 thus blocks the locking lever 122 by providing a counterweight.

[0085] When the hammer 102 is in its cocked position 106 and the locking lever is in its engaged position 126, the hammer 102 and locking lever 122 enter into a releasable engagement 180. More precisely, the first locking element 112 on the hammer side and the second locking element 130 on the locking lever side enter engagement 180. If the locking lever 122 is held in the engaged position 126, the engagement 180 prevents the hammer 102 from being driven into the relaxed position 108 by the spring force of the torsion spring 110. The hammer 102 is thus held or locked in the cocked position 106. If the hammer 102 is now in the cocked position 106, the locking lever 122 in the engaged position 126, and the locking bolt 164 in the blocking position 166, the hammer 102 can no longer be fired without further action. Instead, the holding effect of the locking bolt 164 is transferred to the hammer 102 via the locking lever 122.In other words, locking lever 122 and locking bolt 164 secure the cock 102, with the detent pawl 130 holding the cock 102.

[0086] When the trigger is pulled 160, it swivels, as in Fig. As shown in Figure 1b (see arrow P1), the trigger shaft 162 and the locking bolt 164 coupled to it are moved from the blocking position 166 towards the release position 168 (see arrow P2). During this movement, the locking bolt contact surface 170 and the second contact surface 144 of the locking lever 122 are displaced relative to each other. This requires overcoming a corresponding frictional force, which will be described later.

[0087] Fig. Figure 1b shows a moment when pulling the trigger 160, at which the locking lever 122 is just barely blocked by the locking bolt 164. Fig. 1b the locking lever 122 is therefore still in its engaged position 126, so that the cock 102 cannot yet move into its relaxed position 108.

[0088] In Fig. 1c the trigger blade 160 was moved (see arrow P1) until the locking bolt 164 was in the release position 168 and the locking lever 122 was no longer engaged by the locking bolt 164. As will be described later, the hammer 102 now forces the locking lever 122 against the spring force of the return spring 146 into its release position 128 and pivots the locking lever 122 about the locking lever axis 124 (see arrow P3). As a result, the second contact surface 144 of the locking lever 122 passes the locking bolt 164 on its underside. This is shown in the enlarged view of the contact area of ​​the locking lever 122 and the release bolt 164 in Fig. 1c shown. In addition, the hammer detent 112 and the detent pawl 130 are separated and no longer engaged 180. Now more unhindered, the hammer 102 begins to strike in the direction of its relaxed position 108 (see arrow P4). Fig. 1c shows, as an illustration, a representative example of the Fig. 1a, b and d further optional elements of the trigger system 100, such as a first hammer stop 118a arranged on the hammer 102, a stop 174 coupled to the trigger tongue 160 and a trigger element 178 which, among other things, covers the contact area of ​​locking lever 122 and locking bolt 164 and thus, e.g., stabilizes laterally and also protects against contamination.

[0089] In Fig. 1d the cock 102 is fully depressed and consequently in the relaxed position 108. The locking bolt 164 is in its release position 168 and the locking lever 122 is in its separating position 128.

[0090] Fig. Figure 2 shows the operation of the detent pawl 130. When the hammer 102 is cocked, i.e., moved into its cocked position 106, while the locking lever 122 is in the engaged position 126, the hammer detent means 112 can move the detent pawl 130 from the first detent pawl position 134 (see Figure 2). Fig. 1a) push into the second detent position 136 and thus pass the detent 130. Afterwards, the correspondingly spring-loaded detent 130 moves back into the first detent position 134, which does not allow the hammer 102 to pass again towards the relaxed position 108, but holds it by means of the engagement 180.

[0091] Fig. Figure 3 shows the forces transmitted from the hammer 102 to the locking lever 122 and from the locking lever 122 to the locking bolt 164 (or, more generally, any locking element directly integrated into the trigger mechanism, e.g., a locking surface). A force resulting from the spring force of the torsion spring 110 is transmitted via the hammer detent 112. N⇀ transferred to the locking lever 122 or its first contact surface 142. This force N⇀ acts along the normal vector n⇀ (hereinafter also referred to as surface normal) n⇀ designated) the first contact surface 142 of the locking lever 122.

[0092] The first contact surface 142, or its normal vector n⇀ The imaginary connecting line R between the locking lever axis 124 and the contact surface 142 forms an angle α between 0° and 90°.

[0093] Due to the angle α, the force N⇀ into a force component that points along the connecting line R (without reference sign), and into a force component T⇀, which is perpendicular to the connecting line R, can be decomposed (see parallelogram of forces in Fig. 3) The force component T⇀ is also called the tangential component, since it points along the tangent of an imaginary circle around the locking lever axis 124. The tangential component T⇀ This causes a torque that forces the locking lever 122 into its release position 128. Accordingly, if there is no blockage by the locking bolt 164, the locking lever 122 is automatically forced from the engaged position 126 into the release position 128 by the cocked hammer 102. The tangential component T⇀ is smaller in magnitude than the force N⇀ Due to the leverage effect of the locking lever 122, only a smaller force than the force is exerted at the trigger-side end 140 of the locking lever 122. N⇀ The force is transferred from the second contact surface 144 to the third contact surface 170. The locking lever 122 acts here like a rocker, in which the tangential component acting at the tap-side end 138 T⇀ as a force of equal magnitude (with locking lever arms of equal length) but pointing in opposite directions T'⇀ is transferred to the trigger-side end 140.

[0094] Only a smaller component is transferred via the second contact surface 144 to the third contact surface 170. T⇀'' the power T⇀' transmitted.

[0095] The locking lever 122 thus allows the blocking effect of the locking bolt 164 to be transferred to a region 114 of the tap 102 distal to the tap axis 104. Therefore, the force required to hold the tap 102 is less than in a case where the engagement 180 occurs in a region proximal to the tap axis 104 (without reference numeral). The force is correspondingly lower. N⇀ smaller than in the aforementioned case.

[0096] In total, the force acting from the second contact surface 144 on the third contact surface 170 is T⇀'' reduced compared to the case already described above, in which the blocking of a cocked cock without the locking lever 122 occurs in a region proximal to the cock axis 104. Accordingly, in the system 100 according to the invention, the frictional force Fmin acting between the locking bolt contact surface 180 and the locking lever contact surface 144 is also lower than in the case described above. The frictional force is the force Fmin⇀, which must be overcome at a minimum when pulling the trigger. It therefore determines the lower limit of the trigger pull. The means according to the invention allow the lower limit of the trigger pull to be lowered. In particular, the trigger pull can be reduced below the force range preferred by shooters and therefore adjusted to the desired level by means of additional means, e.g., springs. The lower adjustability is thus improved.

[0097] As especially from Fig. 2. The distal end 116 of the cock 102 is wedge- or paddle-shaped. Furthermore, the cock 102 is dimensioned such that, when the cock 102 is cocked, its distal end 116 is moved with its tip behind the locking lever 122 in its disengaging position 128 and, due to its wedge shape, forces the locking lever towards its engagement position 126.

[0098] Fig. Figures 4a - 4c show embodiments of the trigger system 100 in which the trigger force is adjustable via additional trigger springs. Fig. Figures 4a-4c show an embodiment with two trigger springs 402 and 404. The first trigger spring 402 is coupled to the trigger blade 160 via a first stop 406 such that the spring force F1⇀ the first trigger spring 402 along the entire trigger travel A the pulling on the trigger blade 160 in addition to the force Fmin⇀ counteracts this. Fig. 4b and Fig. Figure 4c shows the second trigger spring 404, which, as in Fig. 4b shown, on the side of the trigger system 100 opposite the first trigger spring 402, or, as in Fig. As shown in Figure 4c, the second trigger spring 404 can be arranged on the same side of the trigger system 100. At its lower end, the second trigger spring 404 has a pressure pin 410 which can come into physical contact with a second stop 408, so that the second trigger spring 404 can be coupled to the trigger blade 160 via the pressure pin 410 and the second stop 408. The distance D between the second stop 408 and the pressure pin 410 can be adjusted via an adjusting element 412 and determines the pre-travel V, i.e., the section of the trigger travel up to the pressure point. The adjusting element 412 allows, in particular, the setting of whether the pressure bolt 410 makes contact with the second stop 408 at the beginning of the trigger travel A (D = 0), between the beginning and end of the trigger travel A (0 < D < A), or not at all along the trigger travel A (D ≥ A). In other words, the adjusting element 412 allows the setting of the spring force. F2⇀ the second trigger spring 404 the pulling on the trigger blade 160 along the entire trigger travel A, along only a part of the trigger travel A or not at all in addition to the force Fmin⇀ counteracts this. The adjusting element 412 may have height adjustment means familiar to the expert, for example threads or detent elements.

[0099] The spring force F1⇀ The first trigger spring 402 can be adjusted, for example, via a second adjusting element 414. For instance, the first trigger spring 402 can be pre-tensioned or relaxed.

[0100] Different trigger profiles can be set using the two trigger springs 402 and 404. Fig. Figure 5 shows an example of such a trigger profile 500. The spring force acts along the entire trigger travel A. F1⇀ the first trigger spring 402. After the pre-travel V comes the spring force F2⇀ the second trigger spring 404. The forces F1⇀ and F2⇀ They therefore add up and determine the trigger force. (Fmin⇀+F1⇀+F2⇀), which must be overcome in order to trigger the striking of the hammer 102 and fire a shot.

[0101] Fig. Figures 6a-6d show further examples of adjustable trigger profiles according to the invention. These trigger profiles correspond, in the case of the ones described in the Fig. In the embodiments shown in 4a - 4c, a specific distance D between the pressure bolt 410 and the second stop 408 is set by means of the adjusting element 412. In addition to the embodiments shown in the Fig. In addition to the trigger profiles shown in 6a - 6d and the respective set distances D, further settings are possible, and the number of settings is not limited to a specific number. For example, one, two, three, four, five, six, or more different distances D can be set.

[0102] The Fig. 6a and Fig. 6b shows trigger profiles for pressure point triggers, such as those in the Fig. The embodiments shown in 4a - 4c can be adjusted. These trigger profiles result from the fact that the second trigger spring 404 couples with the trigger blade 160 at a point between the beginning and end of the trigger travel A. In the Fig. In the trigger profile shown in 6a, the second trigger spring 404 and the trigger blade 160 couple at an earlier point along the trigger travel A than in Fig. 6b, with the consequence that the noticeable pressure point or the higher trigger force is felt earlier than in the case of the Fig. 6b. In other words, in Fig. 6a the preferred route V shorter than in the case of the Fig. 6b. In the Fig. 6a and Fig. The trigger profiles shown in 6b represent the first advantage force for a shooter when pulling the trigger. Fmin⇀+F1⇀ and then, for the haptic recognition of the impending breaking of a shot, the trigger force Fmin⇀+F1⇀+F2⇀ noticeable. Pre-tensioning force and release force are determined by the spring forces. F1⇀ and F2⇀ The spring constants of the two trigger springs 402 and 404 are adjustable. The pre-travel force and the release force can therefore be determined by selecting the trigger springs 402 and 404.

[0103] The Fig. 6c and Fig. 6d shows deduction profiles for direct deductions, such as those found in the Fig. The embodiments shown in 4a - 4c can be adjusted. In the Fig. In the trigger profile shown in 6c, the second trigger spring 404 is coupled to the trigger blade 160 at the beginning of the trigger travel A, so that the sum of the two spring forces is applied along the entire trigger travel A. F1⇀ and F2⇀ The force Fmin counteracts the pulling of the trigger 160 in addition to the force Fmin. In the Fig. The trigger profile shown in 6d does not couple the second trigger spring 404 along the trigger travel A at any point along the trigger travel A or at all with the trigger blade 160, so that only the spring force F1⇀ the first trigger spring 402 the pulling on the trigger blade 160 in addition to the force Fmin⇀ This counteracts the effect. Accordingly, in both cases, only a force and no pressure point is felt when pulling the product off.

[0104] Fig. Figures 7a-7e show a further embodiment of the trigger system 700, in which the first system element is again designed as a locking lever 122 pivotable about a locking lever axis 124. As in Fig. As shown in Figure 7a, the second system element is designed here as a locking piston 764, which is positioned between a blocking position 166, in which the locking lever 122 is blocked, and a position in which Fig. The release position 168 shown in Figure 7b, in which this blockage is lifted, is essentially linearly displaceable. The locking lever 122 has a second contact surface 144 which can come into physical contact with a third contact surface 170 arranged on the locking piston 764, so that in the blocking position 166 the locking lever 122 is engaged, thus blocking its movement towards its release position 128. Furthermore, the trigger system 700 has a return spring 146. Fig. Figure 7d shows an enlarged section of the Fig. 7a, in which the locking lever 122 is in its engaged position 126 and the locking piston 764 is in its blocking position 166. The first and third contact surfaces 144, 170 are touching.

[0105] The locking lever 122 therefore also performs a rotational movement here between its engagement position 126, which holds the cock 102, and its position in Fig. The locking piston 764, which releases the cock 102, can perform a separation position 128 as shown in Figure 7c. The locking piston 764, on the other hand, can perform an essentially translational movement (see arrow P6) when the trigger 160 is pulled. In particular, the locking piston 764 is coupled to the trigger 160 via a lever 774 and a pushrod 772. As shown in Fig. As shown in Figure 7b, pulling the trigger (see arrow P1) causes a translational push movement of the push rod 772 forward and upward (see arrow P5). This push movement causes a rotational movement of the lever 774 (see arrow P3), which in turn causes a substantially translational downward movement of the locking piston 764 (see arrow P6). The substantially translational movement of the locking piston 764 causes the third contact surface 170 of the locking bolt 764 to be moved downwards against the second contact surface 144 of the locking lever 122 until the locking piston 764 reaches its release position 168 and no longer engages the locking lever 122. This shows Fig. 7e, which shows an enlarged section of the Fig. Figure 7c shows the locking lever 122 in its disengagement position 128 and the locking piston in its release position 168. The remaining details regarding the [unclear text] are described in the Fig. The embodiments shown in 1a - 4c apply analogously here. In particular, the cock 102 forces the locking lever 122 from its engagement position 126 to its release position 128 in an analogous manner and then releases freely (see arrow P4).

[0106] The Fig. Figures 8a-8c show another embodiment of the 800 trigger system. As in Fig. Figure 8a shows the first system element, designed here as a locking slide 822, which moves along a linear path by means of a translational movement between an engagement position 126 holding the valve 102 and a position in Fig. The locking slide 822, shown in Figure 8b and releasing the cock 102, is movable back and forth in the separating position 128. Unlike the embodiments shown in the previous figures, the locking slide 822 thus performs a translational movement. For this purpose, the locking slide 822 includes a groove 850 for receiving at least one, preferably at least two, pins 852, which are not part of the locking slide 822 and against which the locking slide 822 is guided and freely displaceable in the groove 850. The locking slide also has a return spring 146 that forces it into its engagement position 126.

[0107] Furthermore, the locking slide comprises a first locking pawl 130 and a second locking pawl 848. The function of the first locking pawl 130 is identical to the function of the locking pawl 130 shown in the previous figures. The second locking pawl 848 engages with the second system element 864, which is designed as a locking bolt and positions the locking slide 822 behind it to block movement into its release position 828.

[0108] The locking bolt 864 is guided in a guide 876 and couples to the trigger blade 160 via a push rod 872. As shown in Fig. As shown in Figure 8b, when the trigger 160 is pulled (see arrow P1), this causes a translational thrust movement of the push rod 872 upwards and forwards (see arrow P5), whereby the locking bolt 864 moves forwards from its blocking position 166 towards its in Fig. The release position 168 shown in Figure 8c is pulled (see arrow P7). In this process, the second contact surface 144, located on the second detent pawl 848, and the third contact surface 170, located on the locking bolt 864, are moved relative to each other until the locking slide 822 is released from its rearward position. The spring-loaded hammer 102 then forces the locking slide 822 against the spring force of the return spring 146 into its release position 128 and then releases. The return spring 146 then forces the locking slide 822 back into its engagement position 126. The groove 852 defines the path of movement of the locking slide 822.

[0109] The spring-loaded second detent pawl 848 allows the locking slide 822 to return to the engagement position 126 even when the locking bolt 864 is in the blocking position 166. For this purpose, the detent pawl 848 can be pivoted upwards when the locking slide 822 moves towards the engagement position 126, allowing the locking slide 122 to pass through.

[0110] Fig. Figure 9 shows the 100 trigger system according to the Fig. 1a-1d, which is arranged in a trigger housing 176 designed as a drop-in part. The drop-in housing design allows for the quick replacement of the entire trigger system 100. In addition, it shows Fig. 9 further optional elements. A first hammer stop 118a is arranged on the hammer 102 and a second hammer stop 118b on the trigger housing 176. When the hammer 102 moves into its cocked position 106, the first hammer stop 118a strikes the second hammer stop 118b and thus prevents the hammer 102 from striking, for example, the breaker 190, which would lead to a disruptive impulse transfer to the trigger blade 160 and ultimately to the shooter's hand. Furthermore, it shows Fig. 9 an optional buffer element 172, which is also arranged on the trigger housing 176, and a further stop 174 movably coupled to the trigger blade 160. The buffer element 172 is arranged between the trigger housing 176 and the further stop 174. If the firearm falls and lands with its front section, e.g. the muzzle, on the ground, an impulse is generated that points in the direction in which the trigger lever 160 is moved when the trigger is pulled (in Fig.9 (symbolized by arrow P5). This impulse can be transferred to moving parts of the trigger system 100, e.g., to the trigger blade 160 or elements coupled to it, and thus lead to the firing of a shot. However, the buffer element 172 buffers this impulse to such an extent that the risk of a shot being fired is significantly reduced compared to the case without the buffer element 172.
