Definitions

  • the invention relates to a two-stage trigger unit, also called a trigger device, which is suitable for handguns, especially for firearms of the rifle type M4 / M16 / AR15, according to the preamble of claim 1.
  • a trigger device which is suitable for handguns, especially for firearms of the rifle type M4 / M16 / AR15, according to the preamble of claim 1.
  • the invention and its variants are not applicable to rifles, carbines, etc. limited, but can in principle also be used for pistols. The improvements and their effects / benefits are listed below.
  • trigger units of this type can be used interchangeably as modules in existing weapons and the weapons themselves only provide the geometrical and functional boundary conditions, the invention primarily relates to such a trigger unit and only secondarily to a weapon with such a trigger unit.
  • a modern trigger unit should generally be easy to use, reliable, easy to maintain and adjustable between a "safe” and at least one "unlocked” state.
  • a large number of trigger units of this type especially for rifles of the AR15 type, which are preferably discussed here, have a construction which prevents the selector from being moved into the "safe” position in the knocked-off position of the hammer. This is often due to the fact that the trigger lever, including one with the selector (also often referred to as a safety lever), the tongue and the trigger latch (usually referred to as "sear") interacting with the hammer (also referred to as a hammer) in one piece is trained. Examples are the US 10,330,413 B2 , the EP 2 950 033 B1 , the US 7,600,338 B2 from which these relationships can be seen very clearly.
  • the object of the present invention is therefore to provide a trigger unit which enables the firearm to be secured when the hammer is knocked off.
  • Another object of the invention is to provide a two-stage trigger unit with different trigger resistances.
  • a further object of the invention is to provide a pull-off unit that is easy to handle, easy to maintain and relatively easy to replace as a "drop-in pull-off unit”.
  • the locking element with its locking element axis and the trigger lever with its trigger axis form a common axis of rotation
  • the locking element having a bearing recess on its upper side for receiving and limited rotation about an interrupter axis of an interrupter joint formed on the underside of the interrupter and wherein the bearing recess has the Interrupter joint is designed to enclose at least partially in the direction of rotation about the interrupter axis.
  • the hammer which is rotatably mounted about a hammer axis and can be pre-tensioned by means of a hammer spring, is no longer blocked by the trigger when it is knocked off.
  • the trigger lever which is rotatably mounted about the trigger axis, comprises an integrally formed trigger and a trigger rear part which is designed to accommodate at least one interrupter.
  • the bearing recess and the interrupter joint are essentially designed to be shaped and complementary to one another in order to enable a rotation about the interrupter axis within limits.
  • the assembly can be done relatively easily by pushing together laterally, as is explained in more detail in the description of the figures. In the installed state, this also ensures that the components of the trigger unit are protected against loss.
  • a trigger unit which is suitable for arrangement in a firearm, preferably a rifle, is designated in its entirety by "2".
  • Fig. 1 shows a schematic exploded view in which a trigger unit 2, shown as a drop-in trigger unit, is shown before it is inserted into a lower housing 1 of a rifle.
  • a slide 11 is shown which, in the rest position of the weapon, that is, before the shot is fired, is mounted above the trigger unit 2 in an upper housing (not shown).
  • a grip 12, a magazine holder 14 and a slide catch lever 15 can be seen on the lower housing 1.
  • a permanent fire group 5 and a selector 6 can be seen in an exploded view, which are not to be seen as part of the trigger unit 2 according to the invention, but should also be described for their function.
  • the permanent fire group 5 comprises, in the usual way, a permanent fire element 51 and a permanent fire spring 52, as well as a sleeve and a pin for fixing in the housing 1.
  • the selector 6 in the form shown comprises two actuating elements and a control shaft 61, the control shaft 61 being arranged inside the housing 1 and being able to be adjusted in its angular position by the two actuating elements from the outside, i.e. by rotation about the transverse direction 92.
  • the control shaft 61 has a geometry which, due to the formation of differently shaped cams along the control shaft 61, interacts with different parts of the trigger unit 2, depending on the position of the selector 6.
  • the control shaft 61 is designed essentially as it is from, for example, the DE 20 2011 004 556 U1 or also the EP 2 950 033 B1 can be seen.
  • Fig. 2a an assembled drop-in trigger unit can be seen in a perspective view, which is shown in the rest position or rest position.
  • the trigger unit 2 according to the invention can theoretically also be installed without the trigger housing 23, i.e. directly in the lower housing 1, provided that smaller adaptations, such as a support for the locking element spring 41 in the housing 1, are provided.
  • the illustrations show the preferred design as a drop-in trigger unit.
  • FIG 2b the rest position of the trigger unit 2 can be seen in a plan view and viewed together Fig. 3 explained:
  • the interrupter 3, which is arranged within the trigger lever 26, can also be seen very clearly.
  • the superimposed representation of the trigger unit 2 with the automatic fire group 5 and the selector 6 can also be seen, as it corresponds to the installation situation and when viewed together Fig. 1 becomes clear.
  • the Fig. 3 shows a further exemplary representation of the trigger unit 2 in an exploded view, the dashed lines being used as reference lines to clarify the position of the components in relation to one another in the installation situation.
  • the multi-part design of the trigger unit 2 according to the invention can be clearly seen from the illustration, with the trigger lever 26 in particular not having a significant characteristic, i.e. no dedicated front section, forward in the direction of travel 91, as can be seen very often in the prior art.
  • the mechanical engagement on the hammer 21 or its release cam 215 does not take place directly with the trigger lever 26, but indirectly via a separately formed latching element 4.
  • the latching element 4 and the trigger lever 26 have a common axis of rotation according to the invention in the installation situation, which is accordingly referred to as both the trigger axis 262 and the latching element axis 43.
  • the latching element 4 is connected to an interrupter 3 according to the invention in such a way that the latching element 4 has a bearing recess 42 on its upper side for receiving and limited rotation of an interrupter hinge 32 formed on the underside of the interrupter 3.
  • a bearing recess 42 encloses the interrupter joint 32 at least partially in the direction of rotation about the interrupter axis 35, which runs in the transverse direction 92 through the interrupter joint 32.
  • this allows a limited rotation of the interrupter around the interrupter axis 35 and through the formation of a common latching element axis 43 or trigger axis 262, the latching element 4 and the interrupter 3 can be individually and jointly tilted or rotated within limits.
  • the latching element 4 and the interrupter 3 are at least partially received laterally by the trigger lever 26.
  • a latching element spring 41 is held on both sides of the trigger lever 26 by the bearing sleeve 24 in the trigger unit 2.
  • the curved rear continuous leg of the locking element spring 41 engages in the illustrated embodiment, see also, for example Figure 5a , on the underside of the trigger housing 23.
  • This type of spring support can also be achieved by a person skilled in the art in other ways, for example by means of corresponding support points on the inside of the lower housing 1.
  • the two loose ends of the locking element spring 41 are supported on the locking element 4 on the underside of the locking element spring supports 412 provided for this purpose.
  • a release edge 44 of the latching element 4 is pretensioned upwards, in the direction of the hammer 21.
  • the hammer 21 is pretensioned in the installation situation by means of a corresponding hammer spring 211.
  • the hammer spring 211 is tensioned in the usual manner with the central connecting piece from below against the hammer 21 and can be counter-supported by the bearing sleeve 24, which holds the trigger 26.
  • laterally protruding hammer spring supports 261 can be provided on the trigger lever 26, which act as an abutment for the hammer spring 21 and thus the hammer spring 21 can be prevented from resting on the locking element spring 41.
  • Trigger unit 2 Due to the inventive support of the hammer spring 21 on the hammer spring supports 261 provided for this purpose, but basically the same on the bearing sleeve 24 or the locking element spring 41, there is also a transmission of force which pushes the trigger lever 26 with its trigger rear part 263 downward in the normal direction 93.
  • This relationship is advantageous for the development of the invention Trigger unit 2, since it transmits a force to be overcome on the trigger 26 and thus noticeably for the shooter on the tongue 264, which is perceived as the first stage (often referred to as "1st stage") and defines the resistance in the idle, which will be explained later.
  • FIGS 4a and 4b the locking lever 4 and the interrupter 3 are shown enlarged.
  • the interrupter 3 has a hook 31 on the upper side, which cooperates with the hammer hook 213.
  • the interrupter 3 has a rear section 33 which, as shown, can have a smaller extension in the transverse direction 92 than the central or front section. This enables easier reception / introduction in / into the trigger rear part 263.
  • the interrupter 3 can, as shown, have a type of support lug formed in the front section for guiding along the top of the latching element 4.
  • the guidance and / or also the support on the upper side of the latching element 4 can, however, also take place through an alternative, functionally identical design of the pairing of the bearing recess 42 and the interrupter joint 32.
  • the interrupter 3 has an interrupter joint 32 on its underside, which is used for receiving and rotatable mounting on the upper side of the latching element 4 and which defines an interrupter axis 35 in the transverse direction 92. Furthermore, a receptacle for an interrupter spring 34 is formed on the underside of the interrupter 3. This in cross section, for example in Figure 5a The better visible receptacle is adapted in diameter and depth to the interrupter spring 34 in such a way that it is secured against slipping out sideways.
  • the latching element 4 as in detail C in FIG Figure 4b shown enlarged, a spring recess 46.
  • This spring recess 46 is formed on the upper side, that is to say facing the interrupter 3, and, like the receptacle in the interrupter 3, serves to at least partially receive and prevent loss of the interrupter spring 34.
  • the spring recess 46 is partially open in at least one transverse direction 92, which facilitates assembly, since the interrupter spring 34 does not have to be compressed to the extent that it can be inserted into the recess or receptacle.
  • a ramp 461 provided laterally in the area of the opening to the spring recess 46 provides further assistance during assembly. As a result of the rise of the ramp 461 in the direction of the spring recess 46, the interrupter spring 34 can be more easily inserted from the side, ie moved over it.
  • the function of the breaker spring 34 is the same in that it biases the breaker 3 about the breaker axis 35, that is to say essentially upwards in the direction of the hammer hook 213.
  • the bearing recess 42 is designed to be essentially complementary in shape and function to the interrupter joint 32, with the interrupter 3 being able to rotate partially, that is to say within defined limits, in addition to the receptacle.
  • the assembly of the locking element 4 and the interrupter 3 is therefore carried out by shifting from one side in the transverse direction 92, avoiding an independent dismantling or falling apart during operation due to the lateral delimitation within the trigger housing 23 or lower housing 1 of the firearm.
  • the sectional views of the different resting and working positions of the Figures 5a, 5c , 6a, 7a , 8a and 8b correspond to a side view through the center plane along the section line A-A ', as exemplified for the rest position in FIG Figure 2b shown.
  • the sectional views of the different resting and working positions of the Figures 5b, 5d , 6b and 7b correspond to a side view through the plane along the section line B-B ', as exemplified for the rest position in Figure 2b shown, which corresponds essentially to a side view without the “left side wall” of the trigger housing 23.
  • the rest position 71, the first trigger stage 72 (1st stage) and the second trigger stage 73 (2nd stage) are illustrated by dashed lines in the area of the tongue 264 and / or the trigger rear part 263.
  • the rest position 71 of the trigger unit is shown.
  • the hammer 21 is cocked, i.e. the hammer spring 211 tries to move the hammer head counterclockwise around the hammer axis 212 ( Fig. 2 ) and rests on the hammer spring supports 261.
  • the hammer 21 has at least one release cam 215 on its outer surface, which is held in the rest position by a release edge 44 of the latching element 4.
  • the release edge 44 is pretensioned by the locking element spring 41 against the hammer 21 by engaging the locking element spring supports 412.
  • the trigger lever 26 is preferably integrally formed and has a tongue 264 which protrudes essentially downward in the normal direction 93.
  • the trigger lever 26 has, in its middle section and in the rearward direction in the trigger rear part 263, a receiving opening for receiving the latching element 4 and the interrupter 3.
  • Figs. 5a and 5b It can be seen very clearly that the tongue 264 of the rest position 71 is pretensioned by the hammer spring 211, since the trigger lever 26 is pressed downwards. It can also be seen very clearly that the selector 6 is in "safe” or “safe” mode, with the control shaft 61 blocking the interrupter 3 on the rear section 33 at the top in a section and preventing an upward deflection.
  • FIG. 5c and 5d A comparative consideration of the Figs. 5c and 5d shows that when a first force is applied to the tongue 264, a slight rearward deflection is possible, with the rear trigger part 263 being rotated upward until the trigger lever 26 on its inner surface 25 comes into contact with the underside of the latching element 4 in the contact area of the detail D. got.
  • This small idle travel is also referred to as idle pull and can be clearly perceived by the shooter through the retaining force of the hammer spring 211 on the trigger 26.
  • This first one Withdrawal resistance is thus perceived between the rest position 71 and the end of the idle period.
  • the end of the empty pass is thus referred to as the first withdrawal stage 72, which in the Anglo-American language area is also often referred to as the “first stage”.
  • the first take-off stage 72 of this two-stage take-off unit 2 can, for example, in FIG Figs. 5c and 5d mapped, perceived.
  • the construction according to the invention enables the same perception of the first trigger stage 72, as a comparison with the Figs. 6 and 7 shows.
  • Figs. 5c and 5d the rest position 71 of the tongue 264 and the trigger rear part 263 can be clearly seen in dashed lines. A further deflection of the trigger 264 to the rear via the first trigger stage 72 is prevented in the "safeguarding" by the upper side of the trigger rear part 263 resting against appropriately designed sections of the control shaft 61.
  • FIG. 9 The detail D from Figure 5a is enlarged in Fig. 9 shown.
  • Particularly advantageous embodiments can be taken from this, which for example consist of a locking element extension 45 formed on the underside of the locking element 4.
  • This allows a defined contact position between the inner surface 25 of the trigger lever 26 and the underside of the latching element 4, whereby the friction can be minimized and the reaching of the first trigger step 72 can be better perceived.
  • a further embodiment comprises the bevel of the inner surface 25 sloping towards the rear, as in FIG Fig. 9 shown.
  • This inclined surface can also advantageously influence the introduction of force between the trigger rear part 263 in the latching element extension 45 by essentially taking place at a right angle - provided the bevel is formed at the corresponding angle. This enables the trigger unit to be triggered very precisely and the first trigger stage 72 to be reached.
  • latching element extensions 45 can as in Fig. 9 be formed integrally on the locking element 4 shown. In this way, a fine adjustment of the idle tension can be carried out by selecting the desired remaining distance between the inner surface 25 and the latching element extension 45 of the respective latching element 4.
  • an adjustable adjusting device 451 preferably designed as an adjusting screw (eg grub screw, worm screw) or also a prismatic adjusting element 451, can function to adjust the part of the latching element extension 45 protruding from the underside.
  • FIGs 11a and 11b For example, two prismatic adjustment elements 451 are shown, which can be inserted laterally in a recess of the latching element 4 that corresponds to the rough outer contour of the prism. Due to the differently rounded edges of the prismatic adjusting element 451, a locking element extension 45 protruding differently from the locking element 4 on the underside can be formed by insertion in the desired position, as a comparison of FIG Figs. 11a and 11b clearly shows.
  • the adjusting elements 451 are designed to be sufficiently large in the transverse direction 92 to ensure stable mounting in the corresponding recess of the latching element 4.
  • the prismatic adjustment elements 451 are exemplified as three-sided prisms, four-, five-, or even multi-sided prisms being fundamentally conceivable.
  • a complementary or alternative possibility for fine adjustment would be to provide various trigger levers 26 with correspondingly adapted inner surfaces 25.
  • Fig. 6 the situation is shown in which the selector 6 is set to the "single fire" position and the control shaft 61 with the corresponding sections enables a slight, further rotation of the trigger rear part 263 about the trigger axis 262.
  • the previously in Fig. 5 A sufficiently described function of the trigger unit 2 until the first trigger stage 72 is reached, a second, usually higher, trigger resistance is thus perceived when the trigger 264 is deflected further towards the rear.
  • This second trigger resistance results in part from the direct transmission of force from the trigger lever 26 to the latching element 4, since after contacting the latching element 4 with the inner surface 25, this jointly around the Trigger axis 262 must be rotated.
  • the hammer spring 211 is still trying to push the trigger 26 downwards.
  • the release edge 44 of the latching element 4 must be brought out of engagement with the release cam 215 of the hammer 21.
  • the rest position 71 and the first trigger stage 72 are indicated schematically as dashed lines on the tongue 264, before the second trigger stage 73 is reached by releasing the trigger edge 44 from the trigger cam 215.
  • the continuous fire unit 5 is as in Fig. 5 shown in its rest position.
  • a further deflection of the trigger 264 to the rear, that is to say a further upward movement of the trigger rear part 263, is limited by the control shaft 61.
  • the hammer 21 By releasing the hammer 21, it is rotated about the hammer axis 212 (see e.g. Figure 8a ) and accelerated within the central recess of the slider 11 on the firing pin.
  • the interrupter 3 tries to rotate upwards around the interrupter axis 35 by the bias of the interrupter spring 34, which is made possible at least within certain limits by the position of the selector 6, until the rear section 33 contacts the corresponding section of the control shaft 61 at the top.
  • this only applies to the case of the pulled tongue 264 - relieving the reins would again require overcoming the first trigger resistance, etc.
  • the hammer 21 is thus caught by the interrupter 3 after each shot in the event of a "single fire".
  • the pretensioning of the interrupter 3 must first relieve the pressure on the tongue 264 so far forward that the trigger edge 44 is positioned in front of the trigger cam 215 again. With further movement of the tongue 264 forwards, the hook 31 is disengaged from the Hammer hook 213 brought. Thus, in turn, at least the second pull-off resistance must be overcome in order to reach the second pull-off stage 73.
  • FIG. 7 Another situation is based on Fig. 7 described, in which the position "continuous fire” of the selector 6 is set. Due to the link-like design of the section of the control shaft 61 corresponding to the rear section 33 in most cases, the interrupter 3 is pressed downwards in this position after the hammer 21 has been released. When firing in the “single fire mode” described above, the interrupter 3 can come into engagement with the hammer 21, while with “continuous fire” an engagement of the hook 31 with the hammer hook 213 is suppressed. So that in the event of "continuous fire” the hammer 21 does not scratch the underside as the slide 11 moves forward, the continuous fire group 5 comes into play in a manner known to the person skilled in the art.
  • the bias of the sustained fire spring 52 briefly brings the sustained fire element 51 into engagement with the sustained fire detent 214 of the hammer 21 when the slide 11 returns.
  • the hammer 21 is held until the locking process is completed and the slider 11 strikes the underside of the continuous fire element 51, whereby the hammer 21 is automatically released again.
  • a central object of the present invention is considered to be the possibility of moving the selector 6 into the "safe” position when the hammer 21 is in the "knocked off” position and thus the trigger unit 2 is not cocked.
  • This situation is in Fig. 8 made clear. How out Figure 8a It can be seen that the hammer 21 is in the knock-off position, as can be the case with a fire-retardant device, that is to say a non-ignited cartridge.
  • the selector 6 is shown in the "continuous fire position", the situation being analogous to the "single fire position". Due to the inventive design of the trigger unit 2, i.e.
  • FIG. 5c shows the trigger edge 44, which on the surface facing the trigger cam 215 preferably has an inclined and / or convex shape.
  • a convex curvature of this surface enables the essentially arcuate movement of the locking element 4 around the trigger axis 262 from reaching the first trigger stage 71 to reduce the contact area between the trigger edge 44 and the trigger cam 215 to a homogeneous increase in the second trigger resistance.
  • the resulting increase in the surface pressure thus increases essentially linearly with the remaining contact area, while an inhomogeneous increase in the pull-off resistance would occur in the case of a release edge 44 with a right-angled design.
  • the release edge 44 has a convex curvature with a radius r 441, measured from the pull-off axis 262 or locking element axis 43 to the apex of the curvature.
  • This radius 441 is preferably smaller than the normal distance between the apex of the convex curvature and the locking element axis 43.
  • the apex can also be set off-center of the release edge 44 in the case of smaller radii in the direction of rotation around the locking element axis 43.
  • the trigger unit 2 is primarily described as a drop-in trigger unit, with at least the hammer 21, the hammer spring 211, the interrupter 3, the interrupter spring 34, the latching element 4, the latching element spring 41, and the Trigger levers 26 are arranged in a trigger housing 23 to form a drop-in trigger unit in accordance with the aforementioned exemplary embodiments.
  • clamping screws 27, such as in Fig. 2a shown, are provided for bracing the drop-in trigger unit. These clamping screws 27 are arranged to penetrate the trigger housing 23 on the underside and can be actuated from above, whereby the positional tolerance in the lower housing 1 of a firearm can be significantly reduced.
  • the invention is not limited to the illustrated and described exemplary embodiment, but can be adapted and modified in various ways. This applies above all to the adaptation to other existing weapons, but also to the dimensions and geometry of the individual parts.
