Trigger system for firearms

Abstract

A trigger system for firearms comprising two system elements. The first system element can be moved back and forth between an engagement position, which brings the first system element into releasable engagement with the cocked cock, and a separating position, which separates the first system element and the cock. The second system element can be moved back and forth between a blocking position, which blocks the first system element against a movement in the direction of the separating position of the first system element, and a release position, which cancels this blocking. The cock is locked in the cocked position when the first system element is in the engagement position and the second system element is in the blocking position. The second system element can be brought into its release position by pulling a trigger coupled thereto, after which the cock forces the first system element into the separating position and strikes for firing.

Description

[0001] Trigger system for firearms

[0002] Technical area

[0003] 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.

[0004] In this application, firearms include in particular short and long weapons, in particular pistols and rifles, in particular assault rifles and precision rifles.

[0005] In this application, position designations such as “top”, “bottom”, “left”, “right”, “front”, “back”, etc. refer to a firearm held in a normal firing position, with the bore axis running horizontally and the shot being fired forwards away from the shooter.

[0006] State of the art

[0007] For firearms, especially assault rifles, a reliable and efficient trigger system that ensures proper firing of the weapon is essential. In particular, the trigger force required to fire, also known as trigger resistance or trigger weight, can significantly influence the discharge and firing results. Excessively high trigger resistance can lead to an inaccurate shot, for example, because the weapon is jerked due to the increased force applied when pulling the trigger. However, too little trigger resistance can also negatively affect precision, e.g., due to insufficient haptic feedback for the shooter, and can also pose a safety risk, e.g., due to the shot being fired unintentionally or too early.

[0008] Different trigger characteristics have proven effective for different operational and training scenarios. There are situations where a direct pull of the trigger without a clear pressure point leads to better results.

[0009] However, many shooters, particularly in situations that require precise firing, want the point along the trigger travel at which the shot is fired to be as precisely identifiable as possible and adjustable in terms of its intensity, especially haptically. Two-stage triggers are used for this purpose, also known as two-stage, two-point or match triggers. With such a two-stage trigger, a pressure point can be felt when the trigger blade is pulled, signaling to the shooter that the shot is about to be fired. Up to this pressure point, along the so-called first stage travel, the shooter works against the so-called first stage force when pulling the trigger. Once the pressure point is reached, the higher trigger force must be overcome to continue pulling the trigger. From this point on, the pull force must therefore be increased.

[0010] The entire trigger travel, i.e. the path along which the trigger blade must be pulled to fire, is made up of two sections with different trigger forces: a first section characterized by the first pull force (also called the first pull travel) and a second section characterized by the release force (also called the release travel).

[0011] Ideally, a trigger system, be it a direct pull or a two-stage trigger, should be as freely adjustable as possible. This allows the trigger dynamics to be changed depending on the shooting situation and preference. In conventional trigger systems, the trigger force is largely influenced by the force of the hammer spring. This spring is tensioned when the hammer is cocked and gives the hammer the energy required to fire a shot. In classic trigger systems, the hammer is initially held in the cocked state by means of a releasable locking mechanism. The hammer and trigger system have corresponding locking devices for this purpose. To fire the shot, this locking connection must be released or the locking devices must be separated. To do this, a resulting frictional force that is directly dependent on the force of the hammer spring must be overcome.Since the hammer must have a relatively high energy to ignite the cartridge's propellant in order to reliably fire a shot, springs with comparatively high spring constants are typically used, so the frictional force to be overcome can also be relatively high. This can lead to high trigger pull resistance and limit the trigger's adjustability.

[0012] Furthermore, it is important to prevent accidental discharge due to inadequate safety mechanisms or the accidental trigger pull. Accordingly, trigger systems should interfere with existing safety mechanisms as little as possible.

[0013] Common solutions use adjusting screws to adjust trigger pull and built-in safety mechanisms that block movement when the trigger is pulled. However, these solutions have limitations, such as the risk of the adjusting screws becoming loose and the safety mechanisms failing.

[0014] DE 3535012 Al and US 2014 / 0196341 Al describe trigger systems for firearms with a hammer that can be moved from a relaxed position to a cocked position to build up the necessary firing energy.

[0015] DE 19626077 C2 discloses a trigger mechanism for a self-loading weapon with a switch to continuous fire. It has a hammer, a bolt, a pawl, a pivotally mounted trigger, and a lever that engages the hammer after each shot and keeps it cocked during the switch to continuous fire. This solution offers a two-stage trigger with a large trigger or pawl contact surface and an optimized pawl loading angle to enable a smooth trigger pull. It also features a safety that blocks the movement of the trigger.

[0016] US 20180149441 A1 proposes a two-stage trigger mechanism for automatic weapons, including spring-loaded links, hammer, and breaker. Calibrated springs allow for adjustable trigger pull weight in the second stage without the need for set screws, preventing accidental trigger pull in manual mounting.

[0017] DE 202023002425 Ul provides a trigger for quick installation and removal in AR 3-type weapons. 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.

[0018] US 7600338 B2 describes a trigger with a stepwise adjustable weight for AR weapons. The trigger unit consists of a spring-loaded hammer, a trigger pull, and a breaker. Calibrated springs are provided to facilitate adjustment of the second-stage trigger pull weight.

[0019] Despite these state-of-the-art solutions, there is a need for a trigger system that offers improved adjustability, especially of the trigger dynamics.

[0020] Task and solution of the invention

[0021] The object of the present invention is to provide alternative, adjustable trigger systems. The invention achieves this object with the subject matter of the independent claims. These and further exemplary embodiments are evident from the dependent claims and the following description.

[0022] One aspect of the invention (claim 1) relates to a trigger system for firearms, in particular assault rifles. This has a hammer that can be moved from a relaxed position to a cocked position to build up the required firing energy. The trigger system further includes a first system element that can be moved back and forth between a first position and a second position. In the first position, the engaged position, the first system element and the hammer in its cocked position come into releasable engagement. In the second position, the disengaged position, the first system element is disengaged from the hammer. The trigger system also has a second system element that can be moved back and forth between a third position and a fourth position. In the third position, the blocked position, the second system element blocks the first system element against movement from the engaged position toward the disengaged position.In the fourth position, the release position, this blockage is released, so that the first system element can be moved unhindered from its engaged position to its disengaged position and vice versa. The hammer is locked in its cocked position when the first system element is in the engaged position and the second system element is in the blocked position. By pulling a trigger coupled to the second system element, the second system element is moved from its blocked position, in which it blocks the first system element, to its release position, in which it does not block the first system element or this blockage is released.Once the second system element has been moved into its release position, the hammer, as a result of the firing energy built up in it by cocking, first automatically pushes the first system element into the release position, which separates the hammer and the first system element, and then fires completely into its uncocked position to fire a shot.

[0023] The hammer, for example, is a common cock in long and short guns, also known as a hammer or firing pin. It is designed to be moved into the cocked position, from which it fires into the uncocked position. When the hammer is moved into the cocked position, a hammer spring, for example, is tensioned, so that the (potential) firing energy generated during cocking is stored in the hammer spring. During firing, i.e. the independent uncocking of the spring after actuation of a trigger mechanism, the firing energy is completely converted - first into kinetic energy during the firing movement and then into the heat required to ignite the cartridge.

[0024] The first system element serves as an intermediary or mediating element / transmission element between the tap and the second system element, which will be described in more detail later. In particular, it can transmit a blocking effect of the second system element to the tap, so that, for example, the tap is indirectly held or locked by the second system element. In other words, the first and second system elements interact to hold or lock the tap in its cocked position. For this purpose, the first system element can be designed, for example, as a bracket or lever, and, particularly due to its blocking effect on the tap, can be referred to as a locking lever or bracket.

[0025] The first system element is movably mounted so that it can be moved back and forth between its engaged and disengaged positions.

[0026] In the engaged position, the first system element comes into releasable engagement with the hammer as soon as the hammer has been cocked, i.e. brought into its cocked position. In some embodiments, which will be described later, the first system element and possibly also the hammer have correspondingly designed locking means. In these embodiments, the releasable engagement can take place via this / these locking means. For example, a first locking means is arranged on the hammer and a second locking means is arranged on the first system element. Regardless of the respective 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 hammer is locked in its cocked position until the blockage is released by the second system element.The engaged position of the first system element therefore holds the hammer in its cocked position until the blockage is released by the second system element. This position is therefore also referred to as the hammer-holding position. This will be described in more detail later.

[0027] When the first system element is in the separated position, the hammer and the first system element are separated in such a way that they cannot engage. In embodiments in which special locking means are provided for engagement, these remaining means cannot engage in the separated position. When the first system element is in this position, the hammer can therefore move unhindered from its cocked position to the uncocked position. The separated position of the first system element is therefore also referred to as the hammer-releasing position. The movement that the first system element performs when moving from one position to the other can be a translational or a rotational movement.

[0028] In certain embodiments, the first system element can be moved for translational movement along a substantially linear path between the engaged and disengaged positions. This path can be entirely straight or partially straight. Additionally or alternatively, the path can have curved sections.

[0029] For translational movement, the first system element can, for example, have a groove or recess that accommodates one or more tongues (in the sense of a tongue-and-groove connection), tenons, or pins. In this case, the groove or its course defines the movement path of the first system element between its engaged and disengaged positions. However, the reverse case is also possible, in which the first system element has one or more tongues, tenons, or pins that are accommodated in a groove defining the movement path. This groove can, for example, be arranged on an additional system element.

[0030] In other preferred embodiments, the first system element performs a rotational movement between its engaged and disengaged positions. It thus moves along a circular path or at least along a circular segment to alternate between the engaged and disengaged positions. For this purpose, it can be mounted rotatably, e.g., around a pivot or pivot point, in particular an axis. For example, this pivot or pivot point is located centrally or in a region around the center of the first system element.

[0031] The second system element can be any component suitable for blocking the first system element. Depending on the specific design, the specialist will use familiar means for the specific selection, e.g., a locking pin, a counterbearing, a catch, or a locking pawl.

[0032] The second system element can come into physical contact with the first system element, e.g. touch it, in order to block it. As already described, when blocked, the first system element is held in its engaged position by the second system element and cannot easily leave this position. The first system element can be blocked, for example, by the second system element placing the first system element behind it. For example, this blocking prevents rotation or translation of the first system element, via which it could reach its released position. The second system element is coupled to a trigger blade directly or indirectly, e.g. via further elements. The second system element can, for example, be designed as a single piece with the trigger blade, or the second system element and trigger blade can be designed as two separate but coupled parts.Alternatively, the second system element can be coupled to the trigger blade via several additional components. The coupling of the second system element to the trigger blade is designed in such a way that pulling the trigger blade also results in a movement of the second system element from its blocking position towards its release position, i.e. from the position blocking the first system element towards the position that releases this blockage. For this purpose, the trigger blade and second system element can, for example, be rigidly coupled or connected to one another so that a movement of the trigger blade is transmitted directly to the second system element. However, a coupling that implements an indirect transmission of the movement of the trigger blade is also possible. In any case, the second system element is moved from its blocking position to its release position by pulling the trigger blade or completely pulling it.The blockage by the second system element can therefore be released by pulling the trigger, e.g., by pulling the trigger blade. For example, the second system element is in its release position outside the path of a 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 then readily possible.

[0033] If the second system element is moved out of the blocking position, the first system element moves automatically into its tap-releasing position. For this purpose, the first system element can be spring-loaded directly or indirectly. For example, the force of the tap spring can be used to move the first system element. For example, the tap or a first locking means arranged on the tap and the first system element or a second locking means arranged on the first system element can be arranged in such a way that a force generated by the tensioned tap spring and acting on the tap is transferred from the tap to the first system element. The first system element, which is not blocked by the second system element, is then moved, in particular pushed, into its release position by this spring force.

[0034] To transfer the force from the tap to the first system element, the first system element can have a contact surface via which it engages with the tap in its engaged position. In addition, the tap can also have a corresponding contact surface so that both contact surfaces come into contact, e.g. touch, 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 surface points downwards with its normal vector. In this case, the surfaces are arranged in such a way that their two normal vectors are anti-parallel to one another and the surfaces at least partially overlap.

[0035] Regardless of whether the tap has a (e.g. direct or indirect) contact surface 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 urges the first system element into its tap-releasing separation position.

[0036] Overall, this aspect of the invention has the advantage, among other things, that the first system element acting as an intermediary allows the blocking effect of the second system element to be transferred to a tap area as far away from the tap's pivot axis as possible. According to the lever principle, this reduces the force required to release the tap's locking mechanism in its cocked position in proportion to the distance from the pivot axis or the tap's pivot point (tap axis or tap pivot point).

[0037] According to one embodiment (claim 2), the required firing energy is generated by a hammer spring, in particular a leg spring, acting on the hammer. Such hammer springs are familiar to those skilled in the art and have the advantage that, as proven devices, they require no design changes.

[0038] According to a further embodiment (claim 3), the second system element blocks the first system element in its blocking position by being positioned behind the first system element. Positioning behind the first system element is a proven and reliable method for blocking a movable element. Advantageously, the skilled person can use proven means such as locking pins, abutments, catches, or locking pawls.

[0039] According to a further embodiment (claim 4), the hammer can have a first locking means and the first system element can have a second locking means that can be brought into releasable engagement with the first locking means. The already described releasable engagement of the cocked hammer with the first system element in its engaged position can in this case take place via the first and second locking means. According to a further embodiment (claim 5), the first system element is pivotally mounted about a pivot point or a pivot axis, specifically such that it can be pivoted between its engaged position and its released position. For example, the pivotable mounting can take place in a region near the center of the first system element. Preferably, it takes place 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 accommodates / 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.

[0040] Alternatively, or additionally, the first system element can be mounted so that it can be moved between its engaged position and its disengaged position.

[0041] According to a further embodiment (claim 6), for example, the second locking means of the first system element has a first contact surface that contacts the first locking means of the tap when the first system element is in the engaged position and the tap is in the cocked position. The first contact surface is designed such that its normal vector encloses an angle α, in particular less than or equal to 90° and greater than 0°, with an imaginary connecting line from the first contact surface to the pivot point of the first system element, so that a force transmitted by the tap and acting along the normal vector results in a force component that acts perpendicular to the connecting line, i.e. in a direction tangential to the circular movement. This tangential force component presses the first system element towards its released position. The first contact surface on the first system element can be arranged on the second locking means of the first system element.Another optional tap-side contact surface can be arranged on the first locking means of the tap.

[0042] By means of the first locking means, at least part of the force acting on the tap is transferred to the second locking means. If the first and second locking means come into contact at the first contact surface, the force transferred from the tap to the second locking means acts along the normal vector of the first contact surface. This force can be used, for example, to pivot the first system element about a pivot or swivel point; e.g. from its engaged to its disengaged position. For this to happen, the force acting along the normal vector of the first contact surface must have a non-zero force component that can urge the first system element from its engaged to its disengaged position or generate 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 any torque. Rather, 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 to the disengaged position.

[0043] The pivoting mount 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 force is transferred by the pivoting mount to the contacting areas of the first and second system elements and contributes to the frictional force that must be overcome during triggering. Since the tangential component is a fraction of the normal force, the trigger pull can be further reduced. The frictional force must at least be overcome during triggering and therefore determines the lower limit of the trigger pull force. The means according to the invention can therefore lower the lower limit of the trigger pull force. In particular, the trigger pull force can be reduced below the force range preferred by shooters and can therefore be adjusted to the desired level using additional means, e.g., springs. The ability to adjust downwards is thus improved.

[0044] If the first contact surface forms an angle with the imaginary connecting line that lies between 90° (normal vector orthogonal to the connecting line) and 0° (normal vector parallel to the connecting line), this advantageously leads to a force component that points in the tangential direction and thus urges the first system element towards the release position. This ensures that the first system element is automatically urged into the valve-releasing position by the valve. The angle is preferably greater than 0° and less than 90°, in particular between 10° and 80°, in particular between 20° and 60°, in particular between 20° and 45°, and particularly preferably between 25° and 30°. According to one embodiment (claim 7), the second locking means is a locking pawl.The locking pawl is pivotally mounted in such a way that the locking pawl allows the first locking element to pass unhindered when the first system element is in its engaged position and the hammer is moved to the cocked position. The second system element is, for example, an abutment.

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

[0046] In the first locking pawl position, the first and second locking elements engage as soon as the hammer is cocked and the first system element is in its engaged position. If the first system element is in its engaged position and the locking pawl is in its first locking position, the first locking element and the locking pawl engage when the hammer moves toward its uncocked position. If the second system element then also blocks the first, the hammer is held or locked in the cocked position.

[0047] In the second latching pawl position, the hammer or the first locking means of the hammer can pass the latch essentially unhindered during cocking of the hammer, even if the first system element is in its engaged position. For example, during cocking of the hammer, i.e. during the cocking movement from the uncocked hammer position to the cocked hammer position, the latch is pushed by the first locking means from its first latching pawl position to its second latching pawl position. The first locking means therefore pushes the latch aside so that it can pass unhindered, even if the first system element is in its engaged position. The first locking means and the latch are in contact, but the latch allows the first latching means to pass. Once the first latching means has passed the latch, the latter then moves independently from its second latching pawl position back to its first latching pawl position.For example, it is spring-loaded so that a spring pushes the locking pawl from its first locking pawl position to its second locking pawl position.

[0048] According to one embodiment (claim 8), the hammer is pivotally mounted about a hammer pivot point and is pivoted about the hammer pivot point for movement from the uncocked position to the cocked position. Furthermore, the end of the hammer facing the first system element is elongated or bow-shaped. Furthermore, the two locking means are arranged such that the releasable engagement occurs in an end region of the hammer distal to the hammer pivot point. Finally, the second system element is arranged such that the blocking of the first system element occurs in a region of the first system element on the trigger blade side, i.e., in a region that, from the perspective of the first system element, lies on the trigger blade side.

[0049] For example, the first system element can have two arms that extend from its pivot point. One arm extends towards an area near the hammer, so that the hammer 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 means is arranged at the hammer-side end of the first system element, it can engage with the first locking means arranged on the hammer. The other arm, on the other hand, can extend into an area near the trigger blade. In this case, the second system element is also arranged in this area near the trigger blade, so that the second system element can block the first via its trigger-side end.

[0050] The two locking devices engage in an end region of the hammer distal to the hammer pivot point, i.e., in an area of ​​the hammer that lies around the end of the hammer facing away from the hammer pivot point. This means that less force is required to hold the hammer in its cocked position than in an engagement that occurs in an end region proximal to the hammer pivot point (lever principle).

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

[0052] This return spring can, for example, be provided on the hammer-side area of ​​the first system element and counteract the force component that forces the first system element into its release position when the second system element is in its release position. For example, the spring constant of the spring can be selected such that the resulting spring force is smaller than the aforementioned force component, yet large enough to move the first system element into its engagement position without the opposing force component. Advantageously, the first system element is thus reliably moved into the hammer-locking engagement position after the shot is fired.

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

[0054] For example, the hammer end mentioned is designed in a shovel-shaped manner. The position of the hammer and / or its length in relation to the first system element in its released position can be selected such that the tip of the wedge-shaped / shovel-shaped hammer end moves behind the hammer-side end of the first system element when the hammer is cocked, and the latter is pushed towards its engaged position due to the wedge or shovel shape. This has the advantage that when the hammer is cocked, the first system element is reliably brought into the engaged position, thus ensuring that the hammer is locked after cocking. This prevents, for example, an unintentional discharge. This represents an additional safety measure that ensures that the first system element is safely moved into its engaged position after the shot has been fired, even if the return spring described above fails.This is particularly advantageous with automatic weapons, where the hammer is automatically returned to its cocked position after the shot is fired.

[0055] The position of the hammer can be adjusted. For example, a hammer spindle can be arranged in a horizontally extending slot. The hammer spindle can be moved horizontally in the slot 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, different hammers can be used with an otherwise identical trigger mechanism. For example, different rifles can use differently designed hammers, but have the same remaining trigger mechanism. By using a slot, the position of the hammer spindle can be adjusted to suit the hammer used. If, for example, a drop-in receiver is used, the drop-in receiver can be mounted first and then the hammer can be plugged in and positioned accordingly using the slot, e.g.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, i.e., along the entire trigger travel, so that its spring force additionally counteracts the pulling of the trigger blade along the entire trigger travel. Advantageously, different trigger profiles can be easily adjusted. The first trigger spring ensures a permanent, constant trigger resistance.

[0057] According to one embodiment (claim 12), the trigger system comprises a second trigger spring and an adjustment element. The second trigger spring can be adjustably coupled to the trigger blade, whereby, 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 adjustment 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.

[0058] For example, the second trigger spring can be a compression spring, and the distance between its end closest to the trigger blade and a coupling point with the trigger blade can be adjustable. For example, the distance can be selected so that the second trigger spring couples with the trigger blade from the beginning of the trigger travel (distance equal to zero), 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).

[0059] In this way, it is possible, for example, to adjust whether the spring force of the second trigger spring additionally counteracts the pulling of the trigger blade either along the entire trigger travel, along a part (between the beginning and the end) of the trigger travel, or not at all.

[0060] The second trigger spring can therefore be connected in an adjustable manner. This allows switching between two different direct triggers (second trigger spring 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 can also be set between the beginning and end of the trigger travel, at which the coupling between the second trigger spring and the trigger blade occurs. This advantageously allows several different two-stage triggers to be set, which differ in the position of the noticeable pressure point along the trigger travel. The forces to be applied (release force, first-stage force) can be determined by selecting the appropriate trigger springs or their respective spring constants.

[0061] The trigger travel can be adjusted or predetermined using one or more stops. For example, an optionally adjustable safety edge can also be coupled to the trigger blade and / or the second system element and move with the trigger during the firing. The trigger travel is then limited by the safety edge striking a fixed component (not coupled to the trigger blade) at a predetermined position. By replacing the safety edge, the trigger travel and trigger characteristics can be further modified.

[0062] 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 part. Drop-in housings are a familiar and simple means for quickly and easily replacing trigger groups or systems. In some embodiments, other parts of the trigger system are also housed in the drop-in housing.

[0063] 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 replaceable.

[0064] For example, the second system element can be removed from the exhaust system and reinstalled in order to replace it with a new second system element, to maintain or repair it, or to clean it. In some of these embodiments, only a partial element of the second system element, which includes the contact surface, can be removed and reinserted for the aforementioned purposes. In some of these embodiments, only the contact surface itself can be removed and reinserted for the aforementioned purposes. In any case, the aforementioned removable and reinsertable elements are elements that can be easily removed and reinserted, e.g., without tools. Advantageously, this makes maintenance, cleaning, and / or replacement easy.

[0065] 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 cannot be moved by movement of the trigger blade. The first and second hammer stops are arranged relative to one another such that the first hammer stop strikes the second hammer stop when the hammer moves into its cocked position, thus reducing direct momentum transfer to the trigger blade. This is based on the observation that when the hammer recoils after firing and strikes a breaker, for example, a pulse is transferred to the trigger blade. This can be perceived as unpleasant or annoying by a shooter. Furthermore, it can accelerate wear on the hammer and the parts against which the hammer strikes.By using easily replaceable tap stops, wear can also be reduced.

[0066] In some of these embodiments, the first and second hammer stops can be made of a harder material than the rest of the trigger system, e.g. to reduce wear. In some other of these embodiments, the first and second hammer stops can be made of a softer material than the rest of the trigger system, e.g. to buffer the momentum transfer or to prevent bounce or reduce the effect of bounce. In some other of these embodiments, the first hammer stop can be made of a harder material and the second hammer stop can be made of a softer material than the rest of the trigger system, or vice versa, e.g. to advantageously combine the two aforementioned effects.

[0067] In some of these embodiments, a first and a second tap stop are arranged on both sides of the tap.

[0068] The first element, which cannot be moved by the movement of the trigger blade, can be, for example, a weapon housing (rifle housing or pistol grip). When using a trigger housing, e.g., as a drop-in component, the first element can also be the trigger housing. In principle, however, the first element can be any suitable weapon part that does not move when the shot is fired.

[0069] According to one embodiment (claim 16), the adjusting element is secured against rotation and / or loss.

[0070] In general, all adjustment elements of the weapon, and in particular the adjustment element mentioned above, can optionally be secured by frictional locking, e.g., by an overlap of a roll pin with the adjustment element. In particular, they can be secured against accidental twisting, excessive twisting, and / or loss, i.e., they can be twist- and / or loss-proof. For example, the adjustment range can be limited (e.g., the maximum extent to which the adjustment element can be turned for adjustment) and, optionally, a defined friction torque can be generated (e.g., to protect against unintentional twisting, e.g., due to vibration). For this purpose, in some of these embodiments, a roll pin can be provided in the housing, and a threaded bolt with a groove on the adjustment element. In this example, the threaded bolt runs through the roll pin, or the groove accommodates the roll pin. The adjustment is then carried out, e.g.by turning the threaded pin, which can then be screwed in or out, e.g., to adjust the preload on a spring. However, the dowel pin and the two ends of the groove limit how far the Z-shaped pin can be screwed in or out. The dowel pin can also be positioned in such a way that it exerts pressure on the threaded bolt, so that an increased frictional force must be overcome to turn it. The threaded bolt is thus deliberately mounted with a stiffer bearing. This is intended to prevent, for example, accidental turning or turning due to vibration or shock.

[0071] According to one embodiment (claim 17), the trigger system further comprises a buffer element arranged on a second element of the firearm that cannot be moved by the movement of the trigger blade. When the trigger blade is not pulled, it contacts the trigger blade or an element movably coupled to it. The buffer element is designed and arranged on the second element in such a way that it buffers a pulse transmitted to the trigger blade or the element movably coupled to it, which is directed in the direction in which the trigger blade is pulled to fire the shot.

[0072] This can improve drop safety or prevent a firearm from being dropped. This is based on the observation that, when a weapon is dropped, the probability of a firearm being discharged is higher if the weapon falls on its front side, e.g., the muzzle, than if it falls on its rear side, e.g., the stock or pommel.

[0073] The second element on which the buffer element is arranged can be, for example, the weapon housing (rifle housing or pistol grip). When using a trigger housing, e.g. as a drop-in part, the second element can also be the trigger housing. In principle, however, the second element can be any suitable weapon part that does not move when the shot is fired. The buffer element is preferably arranged in such a way 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 (generated, for example, by a shock) that points in the direction in which the trigger blade is moved when the trigger is pulled can thus be buffered by the buffer element. In this way, the buffer element reduces bounce behavior (the impulse response) of the trigger when stimulated by a shock-like event.This reduces the risk of an accidental discharge, for example if the weapon falls to the ground.

[0074] Preferably, the buffer element comprises a suitable shock-absorbing material so that said impulse can be absorbed to such an extent that no impulse response or only a sufficiently low impulse response is generated so that no shot is fired.

[0100] Detailed description of the characters

[0101] Figures 1a - 1d show an embodiment of the invention in side view. Fig. 1a shows a trigger system 100 according to the invention with a hammer 102 which can be pivoted about a hammer axis 104. By pivoting, the hammer 102 can be moved between a cocked position 106 (see, for example, Fig. 1b) and a relaxed position 108 shown in Fig. 1d. The hammer 102 is spring-loaded, and a spring 110 (hammer spring) provided as a leg spring urges the hammer 102 from its cocked position 106 into its relaxed position 108. The hammer 102 also has a hammer locking means 112. The hammer locking means 112 is arranged in an end region 114 distal from the hammer axis 104 and thus close to the hammer end 116 distal from the hammer axis 104. The distal end of the tap 116 is wedge- or shovel-shaped.

[0102] The trigger system 100 also has a first system element 122 designed as a locking lever, which is pivotally mounted about a pivot point 124 designed as an axis. The locking lever 122 can be pivoted between an engaged position 126 (see, for example, Fig. 1b) and a disengaged position 128 shown in Fig. 1d. The locking lever 122 has a second locking means 130 designed as a latch, which is pivotally mounted about a latch pivot point 132 (see, for example, Fig. 1b). The latch 130 can be pivoted between a first latch position 134 (see, for example, Fig. 1b) and a second latch position 136 shown in Fig. 2. The locking pawl 130 has a first contact surface 142 at the tap-side end 138 of the locking lever 122. Furthermore, the locking lever 122 has a return spring 146 at its end 138 facing the tap 102.At the opposite end 140 on the trigger blade side, the locking lever 122 has a second contact surface 144 on the trigger blade side (see enlargement).

[0103] The trigger system 100 further comprises a trigger blade 160, which is pivotable about a trigger axis 162 (see, for example, Fig. 1b). The trigger blade 160 is coupled to a second system element 164 designed as a locking pin such that a movement of the trigger blade 160 is transmitted to the locking pin 164. The locking pin 164 can be moved back and forth between a blocking position 166 (see, for example, Fig. 1a) and a release position 168 shown in Fig. 1d. Furthermore, the locking pin 164 has a locking pin contact surface 170 (see enlarged view) that contacts the second contact surface 144 of the locking lever 122 for blocking.

[0104] Finally, the trigger system 100 has a breaker 190 familiar to those skilled in the art, which is spring-loaded via a breaker spring 192.

[0105] When the trigger blade 160 is not pulled, the locking pin 164 assumes the blocking position 166. If the locking lever 122 is in the engaged position 126 and the locking pin 164 is in the blocking position 166, the locking pin 164 acts as an abutment for the locking lever 122 and prevents the locking lever 122 from being moved into the release position 128. The locking pin 164 thus blocks the locking lever 122 by a rearward position.

[0106] If 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 come into releasable engagement 180. More precisely, the first locking means 112 on the hammer side and the second locking means 130 on the locking lever side come into 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 uncocked position 108 by the spring force of the leg spring 110. The hammer 102 is thus held or locked in the cocked position 106. If the hammer 102 is in the cocked position 106, the locking lever 122 is in the engaged position 126, and the locking pin 164 is in the blocking position 166, the hammer 102 can no longer be easily fired. Rather, the holding effect of the locking pin 164 is transmitted or mediated to the hammer 102 via the locking lever 122.In other words, locking lever 122 and locking pin 164 secure the hammer 102, with the latch 130 holding the hammer 102.

[0107] If the trigger blade 160 is now pulled, it pivots, as shown in Fig. 1b (see arrow P1), about the trigger blade axis 162, and the locking pin 164 coupled to it is moved from the blocking position 166 toward the release position 168 (see arrow P2). In doing so, the locking pin contact surface 170 and the second contact surface 144 of the locking bracket 122 are displaced relative to each other. For this to happen, a corresponding frictional force, described later, must be overcome.

[0108] Fig. 1b shows a moment when pulling the trigger 160, at which the locking lever 122 is still blocked by the locking pin 164. In Fig. 1b, the locking lever 122 is therefore still in its engaged position 126, so that the hammer 102 cannot yet fire into its uncocked position 108.

[0109] In Fig. 1c, the trigger blade 160 has been moved so far (see arrow P1) that the locking pin 164 has been moved into the release position 168 and the locking pin 164 no longer holds the locking lever 122 back. As will be described later, the hammer 102 now urges 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 pin 164 on its underside. This is shown in the enlarged view of the contact area between the locking lever 122 and the spring pin 164 in Fig. 1c. In addition, the hammer locking means 112 and the locking pawl 130 are separated and no longer engaged 180. Now unhindered, the hammer 102 begins to strike toward its relaxed position 108 (see arrow P4). Fig. 1c shows, for illustration, a representative of Fig.la, 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 blade 160 and a trigger element 178 which, among other things, covers the contact area of ​​the locking lever 122 and the locking pin 164 and thus, for example, stabilizes it laterally and also protects it against contamination.

[0110] In Fig. 1d, the hammer 102 is fully released and consequently in the uncocked position 108. The locking pin 164 is in its release position 168 and the locking lever 122 is in its disconnected position 128.

[0111] Fig. 2 shows the operation of the locking pawl 130. If 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 locking means 112 can push the locking pawl 130 from the first locking pawl position 134 (see Fig. 1a) into the second locking pawl position 136, thus allowing the locking pawl 130 to pass. The correspondingly spring-loaded locking pawl 130 then moves back to the first locking pawl position 134, which does not allow the hammer 102 to pass toward the uncocked position 108, but instead holds it by means of the engagement 180.

[0112] Fig. 3 shows the forces transmitted from the hammer 102 to the locking lever 122 and from the locking lever 122 to the locking pin 164 (or, generally, any locking element directly integrated into the trigger, e.g., a locking surface). A force N resulting from the spring force of the leg spring 110 is transmitted via the hammer detent 112 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 the surface normal n) of the first contact surface 142 of the locking lever 122.

[0113] The first contact surface 142, or its normal vector n, forms an angle a between 0° and 90° with an imaginary connecting line R between the locking lever axis 124 and the contact surface 142.

[0114] Due to the angle α, the force N can be broken down into a force component pointing along the connecting line R (without reference symbol) and a force component T perpendicular to the connecting line R (see force parallelogram in Fig. 3). The force component T is also referred to as the tangential component because it points along the tangent of an imaginary circle around the locking lever axis 124. The tangential component T causes a torque that pushes the locking lever 122 into its released position 128. Accordingly, if there is no blockage by the locking pin 164, the locking lever 122 is automatically pushed by the cocked hammer 102 from the engaged position 126 into the released position 128. The tangential component T is smaller in magnitude than the force N.Due to a lever effect of the locking lever 122, only a smaller force than the force N is transmitted via the second contact surface 144 to the third contact surface 170 at the trigger-side end 140 of the locking lever 122. The locking lever 122 acts here like a rocker, in which the tangential component T acting at the hammer-side end 138 is transmitted to the trigger-side end 140 as a force T' of equal magnitude (with locking lever arms of equal length) but pointing in the opposite direction.

[0115] Via the second contact surface 144, only a smaller component T" of the force V is transmitted to the third contact surface 170.

[0116] The locking lever 122 thus allows the blocking effect of the locking pin 164 to be transferred to a region 114 of the hammer 102 distal to the hammer axis 104. Therefore, the force required to hold the hammer 102 is smaller than in a case where the engagement 180 occurs in a region proximal to the hammer axis 104 (without reference symbol). Accordingly, the force N is also smaller than in the aforementioned case.

[0117] Overall, the force T" acting from the second contact surface 144 on the third contact surface 170 is reduced compared to the case already described and mentioned above, in which the blocking of a cocked hammer without the locking lever 122 occurs in a region proximal to the hammer axis 104. Accordingly, in the system 100 according to the invention, the frictional force Fmin acting between the locking pin contact surface 180 and the locking lever contact surface 144 is also lower than in the above-mentioned case. The frictional force is the force Fmin that must at least be overcome during firing. It therefore determines the lower limit of the trigger force. The means according to the invention can therefore lower the lower limit of the trigger force. In particular, the trigger force can be reduced below the force range preferred by shooters and can therefore be adjusted to the desired level using additional means, e.g., springs. The downward adjustment capability is thus improved.

[0118] As can be seen particularly from Fig. 2, the distal end 116 of the hammer 102 is wedge- or scoop-shaped. Furthermore, the hammer 102 is dimensioned such that, when the hammer 102 is cocked, its distal end 116 is moved with its tip behind the locking lever 122 in its release position 128 and, due to the wedge shape, urges the locking lever toward its engagement position 126. Figs. 4a-4c show embodiments of the trigger system 100 in which the trigger force is adjustable via additional trigger springs. 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 of the first trigger spring 402 counteracts the pulling on the trigger blade 160 along the entire trigger travel A in addition to the force Fmin. Figures 4b and 4c show the second trigger spring 404, which, as shown in Fig.4b, on the side of the trigger system 100 opposite the first trigger spring 402, or, as shown in Fig. 4c, on the same side of the trigger system 100. The second trigger spring 404 has a pressure pin 410 at its lower end, 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 first-stage travel V, i.e. the travel section along the trigger travel up to the pressure point. In particular, the adjusting element 412 can be used to adjust whether the pressure bolt 410 comes into 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 adjustment element 412 can be used to adjust whether the spring force F2 of the second trigger spring 404 counteracts the pulling of the trigger blade 160 along the entire trigger travel A, along only a portion of the trigger travel A, or not at all in addition to the force Fmin. The adjustment element 412 can have height adjustment means familiar to those skilled in the art, for example, threads or locking elements.

[0119] The spring force Fl of the first trigger spring 402 can be adjusted, for example, via a second adjustment element 414. For example, the first trigger spring 402 can be more strongly pretensioned or relaxed.

[0120] Different trigger profiles can be set using the two trigger springs 402, 404. Figure 5 shows an example of such a trigger profile 500. The spring force F1 of the first trigger spring 402 acts along the entire trigger travel A. After the first-stage travel V, the spring force F2 of the second trigger spring 404 is added. The forces F1 and F2 therefore add up and determine the trigger force (Fmin + F1 + F2), which must be overcome to cause the hammer 102 to fire and a shot to be fired. Figures 6a - 6d show further examples of trigger profiles adjustable according to the invention. In the case of the embodiments shown in Figures 4a - 4c, these trigger profiles each correspond to a specific distance D between the pressure bolt 410 and the second stop 408, which distance is set by means of the setting element 412. In addition to the trigger profiles shown in Figures 6a - 6d.Depending on 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.

[0121] Figures 6a and 6b show trigger profiles for two-stage triggers, such as those that can be set with the embodiments shown in Figures 4a-4c. These trigger profiles result from the second trigger spring 404 coupling with the trigger blade 160 at a point between the beginning and end of the trigger travel A. In the trigger profile shown in Fig. 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 result that the noticeable pressure point or the higher trigger force can be felt earlier than in the case of Fig. 6b. In other words, the first stage travel V is shorter in Fig. 6a than in the case of Fig. 6b. In the trigger profiles shown in Figures 6a and 6b, a shooter first feels the first pull force Fmin + Fl and then the release force Fmin + Fl + F2 for haptic detection of the impending firing of a shot.The pre-action force and release force can be adjusted via the spring forces F1 and F2 of the two trigger springs 402, 404, or their respective spring constants. The pre-action force and release force can therefore be determined by selecting the trigger springs 402, 404.

[0122] Figures 6c and 6d show trigger profiles for direct triggers, such as can be set with the embodiments shown in Figures 4a - 4c. In the trigger profile shown in Figure 6c, the second trigger spring 404 already couples with the trigger blade 160 at the beginning of the trigger travel A, so that along the entire trigger travel A, the sum of the two spring forces Fl and F2 counteracts the pulling of the trigger blade 160 in addition to the force Fmin. In the trigger profile shown in Figure 6d, the second trigger spring 404 does not couple with the trigger blade 160 at any point along the trigger travel A, or not at all, so that only the spring force Fl of the first trigger spring 402 counteracts the pulling of the trigger blade 160 in addition to the force Fmin. Accordingly, in both cases, only a force and no pressure point is felt when pulling.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 shown in Fig. 7a, however, the second system element here is designed as a locking piston 764, which is essentially linearly displaceable between a blocking position 166, in which the locking lever 122 is blocked, and a release position 168, shown in Fig. 7b, in which this blockage is released. 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 positioned rearward, blocking its movement toward its release position 128. Furthermore, the trigger system 700 has a return spring 146. Fig. 7d shows an enlarged section of 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 touch each other.

[0123] Here, too, the locking lever 122 performs a rotational movement between its engaged position 126, which holds the hammer 102, and its separated position 128, shown in Fig. 7c, which releases the hammer 102. The locking piston 764, on the other hand, can perform a substantially translational movement (see arrow P6) when the trigger blade 160 is pulled. In particular, the locking piston 764 is coupled to the trigger blade 160 via a bracket 774 and a push rod 772. As shown in Fig. 7b, pulling the trigger (see arrow P1) causes a translational pushing movement of the push rod 772 forward and upward (see arrow P5). This pushing movement causes a rotational movement of the bracket 774 (see arrow P3), which in turn causes a substantially translational movement of the locking piston 764 downward (see arrow P6).The essentially translational movement of the locking piston 764 causes the third contact surface 170 of the locking pin 764 to be displaced downward against the second contact surface 144 of the locking lever 122 until the locking piston 764 reaches its release position 168 and no longer rests the locking lever 122. This is shown in Fig. 7e, which shows an enlarged section of Fig. 7c, in which the locking lever 122 is in its release position 128 and the locking piston is in its release position 168. The remaining explanations for the embodiments shown in Figs. 1a - 4c apply analogously here. In particular, the tap 102 similarly urges the locking lever 122 from its engagement position 126 into its release position 128 and then releases (see arrow P4).

[0124] Figures 8a-8c show a further embodiment of the trigger system 800. As can be seen in Fig. 8a, the first system element is designed here as a locking slide 822, which can be moved back and forth along a linear path by means of a translational movement between an engaged position 126 holding the hammer 102 and a separated position 128, shown in Fig. 8b and releasing the hammer 102. Unlike in the embodiments shown in the previous figures, the locking slide 822 thus performs a translational movement. For this purpose, the locking slide 822 comprises 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 freely displaceable in the groove 850 while guided. The locking slide also has a return spring 146 which urges it into its engaged position 126.

[0125] Furthermore, the locking carriage 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 serves to engage with the second system element 864, which is designed as a locking bolt and which positions the locking carriage 822 behind in order to block movement into its release position 828.

[0126] The locking bolt 864 is guided in a guide 876 and coupled to the trigger blade 160 via a push rod 872. If, as shown in Fig. 8b, the trigger blade 160 is pulled (see arrow P1), this causes a translatory pushing movement of the push rod 872 upwards and forwards (see arrow P5), whereby the locking bolt 864 is pulled from its blocking position 166 forwards toward its release position 168 shown in Fig. 8c (see arrow P7). In this process, the second contact surface 144 arranged on the second latch 848 and the third contact surface 170 arranged on the locking bolt 864 are displaced relative to one another until the rearward position of the locking slide 822 is released. The spring-loaded hammer 102 then pushes the locking slide 822 against the spring force of the return spring 146 into its release position 128 and then fires. The return spring 146 then pushes the locking slide 822 back into its engagement position 126.The groove 852 determines the path of movement of the locking carriage 822.

[0127] The spring-loaded second latch 848 allows the locking slide 822 to be returned to the engaged position 126 even when the locking bolt 864 is in the blocking position 166. For this purpose, the latch 848 can be pivoted upward upon movement of the locking slide 822 toward the engaged position 126, allowing the locking slide 122 to pass.

[0128] Fig. 9 shows the trigger system 100 according to Figs. 1a-1d, which is arranged in a trigger housing 176 designed as a drop-in part. The drop-in housing design allows for quick replacement of the complete trigger system 100. Fig. 9 also shows 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 interrupter 190, which leads to a disruptive impulse transfer to the trigger blade 160 and ultimately the hand of the shooter. Furthermore, Fig. 9 shows an optional buffer element 172, which is also arranged on the trigger housing 176, as well as 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 on the ground with its front area, e.g., the muzzle, a pulse is generated that points in the direction in which the trigger sling 160 is moved during the firing (symbolized by the arrow P5 in Fig. 9). This pulse can be transmitted to moving parts of the trigger system 100, e.g., to the trigger blade 160 or elements coupled thereto, and thus lead to the firing of a shot. However, the buffer element 172 buffers this pulse to such an extent that the risk of a shot being fired can be significantly reduced compared to the case without the buffer element 172.
