Abstract
The invention relates to a trigger device for a firearm, in particular a self-loading military rifle, especially an attack rifle, having a trigger piece (11), a sear release part (9) connected to the trigger piece (11) and at least one trigger spring (29) which acts on the sear release part (9). This trigger device is characterized in that the trigger piece (11) is arranged separately from the sear release part (9) between two stops (35, 37), one (35) of which prevents the movement of the trigger piece (11) relative to the sear release part (9) forwards, while the other (37) prevents such movement to the rear, with a short movement of the trigger piece (11) relative to the sear release part (9) being possible between the two stops (35, 37) and a lost-motion spring (33) acting on the trigger piece (11) and being preferably arranged between the trigger piece (11) and the sear release part (9), pushing the trigger piece (11) forwards considerably more weakly than does the trigger spring (29).
Description
Two-way Trigger The invention relates to a trigger device for a firearm, in particular a self-loading military rifle, especially an attack rifle, having - a trigger piece, - a sear release part connected to the trigger piece and - at least one trigger spring which acts on the sear release part (generic part of Claim 1).
In this documentation we assume a firearm which is held in the normal horizontal firing position when being horizontally fired. "To the front" accordingly means "to the muzzle", the grip is seated "below" etc.
More than 100 years ago the so-called "double pull trigger" was introduced in the German army. In the case of other armies it was normal to place the finger on the trigger while shooting and continuously increase the pressure until - after traveling a rather small trigger path - the shot went off. In the case of the double pull trigger on the other hand a defined, additional trigger path with a defined trigger resistance was present; once this trigger path had been traveled then the trigger resistance increased, and after the traveling of a further, rather small trigger path the shot went off. The advantage of this device was that one could place the finger upon the trigger without having to risk the shot going off upon the slightest movement. Thus one could also place the finger upon the trigger with cold hands or while shaking from nervousness and "take the pressure point ", according to which the shot could be discharged more precisely or could be avoided than would have otherwise been the case (in the case of a so-called "flint trigger").
However, the disadvantage was that the triggering of the shot was in principle slowed down and a greater trigger path was required. For this reason this "double pull trigger"
was introduced, even if only in a few armies, because many armies were already equipped with a rifle which had been designed prior to the invention of the "double pull trigger".
In the case of automatic firearms the double pull trigger was in principle excluded, since there was simply no room for it in the complicated mechanism, and since in other respects it would have been necessary at least prior to each first shot or burst of fire to move the trigger over the long path to the pressure point. Instead of this one devised a device for the adjustment of the trigger spring with whose help it was possible if necessary to switch between winter operation (hard trigger) and summer operation (soft trigger).
Nevertheless, it would be preferable if the trigger had a short path that could be adjusted by force and if necessary also by distance to be covered before it reached the pressure point", that is the place at which the discharging of the shot takes place in the case of a hardening trigger. In the process this device, if at all, should only take up such slight additional space, that the accommodation in an existing automatic firearm is possible, to be precise, also if in the case of said existing automatic firearm the original sear release part was designed as the trigger itself. This latter named task appears upon first glance to be completely impossible, but is however, as we shall see, realizable by means of the invention. In the process however the trigger path which is traveled before the pressure point is reached has to be rather short in order to still be able to accommodate the trigger in an existing trigger guard, and in order to likewise facilitate the emission of rapidly succeeding single shots or bursts of fire, Printed: 22-10-2008 DESCPAMD PCT/EP 2007/006 781 as was the case with the previous trigger, wherein the function, as always intended, should be improved.
This problem is solved in accordance with the invention by the features of Claim 1.
It is true that bisecting the trigger for the production of a double pull trigger and placing a lost-motion spring between the two parts is already known (FR 2 619 440 A).
Arranging a spring between the trigger and the disconnector in order to improve the function is also known (US 6 772 5481B1). However, arranging the latter named spring between the sear release part and the disconnector and not, as would be obvious, between the trigger piece and the sear release part, is not obvious. In the case of the invention the force of the lost-motion spring can therewith be practically freely selected.
The excessive movement of the trigger piece (of the actual trigger) forwards is prevented by the first of the stops, while the second of the stops establishes the firm connection between the trigger piece and the sear release part when pulled over a lost-motion distance. The two stops hence define a lost-motion distance of the trigger.
The distance of these stops, that is the lost-motion distance, can constructively be freely selected, so that the additional trigger path is selected in such a way that it is compatible with the present conditions (trigger guard, other operating elements).
However, the requirement is a lost-motion spring which presses the trigger forwards over the lost-motion distance - the force of this spring must, in proportion to the trigger spring, which loads the sear release part, be significantly lower, so that a well perceivable pressure point remains when the lost motion of the trigger piece has been traveled and the trigger piece is at the pressure point.
In this documentation we assume a firearm which is held in the normal horizontal firing position when being horizontally fired. "To the front" accordingly means "to the muzzle", the grip is seated "below" etc.
More than 100 years ago the so-called "double pull trigger" was introduced in the German army.

Nevertheless, it would be preferable if the trigger had a short path that could be adjusted by force and if necessary also by distance to be covered before it reached the pressure point", that is the place at which the discharging of the shot takes place in the case of a hardening trigger. In the process this device, if at all, should only take up such slight additional space, that the accommodation in an existing automatic firearm is possible, to be precise, also if in the case of said existing automatic firearm the original sear release part was designed as the trigger itself. This latter named task appears upon first glance to be completely impossible, but is however, as we shall see, realizable by means of the invention. In the process however the trigger path which is traveled before the pressure point is reached has to be rather short in order to still be able to accommodate the trigger in an existing trigger guard, and in order to likewise facilitate the emission of rapidly succeeding single shots or bursts of fire, Printed: 22-10-2008 DESCPAMD PCT/EP 2007/006 781 as was the case with the previous trigger, wherein the function, as always intended, should be improved.
This problem is solved in accordance with the invention by the features of Claim 1.
It is true that bisecting the trigger for the production of a double pull trigger and placing a lost-motion spring between the two parts is already known (FR 2 619 440 A).
Arranging a spring between the trigger and the disconnector in order to improve the function is also known (US 6 772 5481B1). However, arranging the latter named spring between the sear release part and the disconnector and not, as would be obvious, between the trigger piece and the sear release part, is not obvious. In the case of the invention the force of the lost-motion spring can therewith be practically freely selected.
The excessive movement of the trigger piece (of the actual trigger) forwards is prevented by the first of the stops, while the second of the stops establishes the firm connection between the trigger piece and the sear release part when pulled over a lost-motion distance. The two stops hence define a lost-motion distance of the trigger.
The distance of these stops, that is the lost-motion distance, can constructively be freely selected, so that the additional trigger path is selected in such a way that it is compatible with the present conditions (trigger guard, other operating elements).
However, the requirement is a lost-motion spring which presses the trigger forwards over the lost-motion distance - the force of this spring must, in proportion to the trigger spring, which loads the sear release part, be significantly lower, so that a well perceivable pressure point remains when the lost motion of the trigger piece has been traveled and the trigger piece is at the pressure point.
Now if the automatic firearm or the weapon was originally equipped with a trigger piece which is connected in a single piece to the sear release part, so that the flint trigger is indispensable/unalterable, then it is sufficient to separate the trigger piece structurally from the sear release part and provide the stops as well as the lost-motion spring in order to provide a weapon which constructively actually cannot have one with a double pull trigger. This is the special accomplishment of the invention, because any person skilled in the art would have scrapped the present basic construction/framework and redesigned it from the ground up if they wanted a double pull trigger.
The trigger piece could for example be relocatably mounted in the direction of fire in the sear release part between the two stops. This however carries the risk that the lost motion of the trigger piece over the course of time will become stiff. While it is true that the weapon will then function as always, however; this will only be possible with a flint trigger. For this reason in accordance with the invention it is preferred that the trigger piece is pivoted around a transverse axis on the sear release part (Claim 2).
However, a soiling of the pivot bearing can be practically ruled out. Moreover, another advantage is present in that the trigger piece only exhibits an extremely slight lost motion where it emerges from the housing, said lost motion lying within the tolerances of the corresponding slot/slit in the housing. Hence, if a weapon is intended to be retrofitted to the inventive trigger no modification is to be performed on the housing.
Another embodiment of the invention consists in the fact that at least one of the stops is constructed as a horizontal area on the trigger piece and/or on the sear release part (Claim 3). In the simplest case an upper area is constructed on the trigger piece and a lower area is constructed on the sear release part, said area extending over the entire corresponding part. Both areas extend slightly angled to each another, so that in the case of an unpulled trigger the front parts, in the case of a pulled trigger the rear parts of the areas are seated upon each other.
A preferred embodiment of the invention lies in the fact that the lost-motion spring between the two areas is active and preferably is arranged behind the pivot bearing between said areas (Claim 4). Thus the lost-motion spring is practically arranged within the trigger and requires no external space whatsoever. In the preferred case the lost-motion spring is moreover constructed as a pressure spring, so that its arrangement is easily possible by placement in on or two boreholes which are constructed in the trigger piece and/or in the sear release part. For retrofitting in an automatic weapon another, two-way trigger is simply to be installed.
In accordance with a further embodiment of the invention it is especially preferred that an adjusting screw for the pressure point path is arranged in front of the pivot bearing and across the area (Claim 5). With this adjusting screw the location of the front stop, which becomes active in the resting position of the trigger, can be modified, so that the trigger within the given boundaries can either be set so that a maximum lost-motion (pressure point path) is achieved, or so that in each case an equal lost motion is achieved.
Moreover, if necessary a setting which accommodates the properties of the marksman can be performed.
In accordance with a further embodiment of the invention an additional advantage lies in the fact that the lost-motion spring can be adjusted or replaced. Thus not only can a rusted or worn out spring be replaced with a new one, but rather also the prevailing force during the lost-motion path is adjustable, so that either the pressure point can be custom set, or can be adapted to the properties of the respective trigger, for example, in the case of a very light "summer trigger" is still clearly perceptible, on the other hand in the case of the "winter trigger" is still distinctly perceptible through the glove.
Overall it has been managed with only three additional parts (trigger piece, transverse axis and lost-motion spring) and within the confines of a conventional trigger device to drastically change its properties.
The subject matter of the invention will be explained more closely with the help of the exemplary embodiments with the attached drawing. The figures show the following:
Figure 1 shows the longitudinal section through an inventive trigger device with the safety catch on.
Figure 2 shows the longitudinal section through an inventive, two-way trigger.
Figure 3 shows the top view of the trigger with trigger spring.
Figure 4 shows a representation similar to Figure 1, however in with the safety catch off.
Figure 5 shows a representation similar to Figure 4, however right before the discharge, and Figure 6 shows the trigger of a modified design.
With the help of Figure 1 first a conventional trigger device not shown in all details will be explained.

Overall it has been managed with only three additional parts (trigger piece, transverse axis and lost-motion spring) and within the confines of a conventional trigger device to drastically change its properties.
The subject matter of the invention will be explained more closely with the help of the exemplary embodiments with the attached drawing. The figures show the following:
Figure 1 shows the longitudinal section through an inventive trigger device with the safety catch on.
Figure 2 shows the longitudinal section through an inventive, two-way trigger.
Figure 3 shows the top view of the trigger with trigger spring.
Figure 4 shows a representation similar to Figure 1, however in with the safety catch off.
Figure 5 shows a representation similar to Figure 4, however right before the discharge, and Figure 6 shows the trigger of a modified design.
With the help of Figure 1 first a conventional trigger device not shown in all details will be explained.
A hammer 1 is provided, which is cocked by a mainspring (not shown) around a transverse axis 3 and which exhibits two catches: one trigger catch 5, into which the sear arm 7 of a single part trigger 9, 11 engages, and a disconnector catch 13, into which the disconnector nose 17 of a disconnector 15 can engage, said disconnector 15 being pivoted in a longitudinal slot 19 of the trigger 9, 11 around an axis 21 and being elastically pressed upwards by a disconnector spring 23. A safety roller 25 holds the rear part of the trigger 9, 11 tight, so that it is fixed around the axis 21.
Parts 9 and 11 however form a single component in the case of the known trigger device, different than shown in Figure 1, where the inventive two-way trigger is shown.
If the safety roller 25 is turned, as is shown for example in Figures 4 and 5, then the trigger 9, 11 in the case of actuation can carry out a counterclockwise rotary movement until the trigger piece 7 releases the trigger catch 5. This rotary movement is however in the case of the known single piece trigger 9, 11 quite short. At the same time the disconnector nose 17 lies on the hammer I and is pushed back against the spring 23. Now the hammer 1 can move counterclockwise and releases. In the process, the trigger 9, 11 remains in its position.
The release of the hammer 1 discharges a shot, on the basis of which the breech (not shown) is pushed back and the hammer I is cocked again clockwise. In the process the disconnector nose 17 is first pressed against the spring 23 into the longitudinal groove 19 and then engages in the hammer via the disconnector catch 13, said hammer being held by the catch 13 and nose 17.
Printed: 22-10-2008 DESCPAMD PCT/EP 2007/006 781 If the trigger 9, 11 is now released, then the trigger piece 7 presses against the hammer 1 before the disconnector catch 17 is pulled back so far that it releases the disconnector catch 13. The hammer 1 engages a little bit (counterclockwise) forwards and engages with its trigger catch 5 back in the trigger sear 7.
In accordance with the invention, however, as shown the trigger 9, 11 is broken down into two parts, namely a sear release part 9 and a trigger piece 11, which are flexibly connected to each other by a transverse axis 27. A lost-motion spring 33 in the process loads the trigger piece 11 clockwise around the transverse axis 27 until the trigger piece is seated in a front catch 35 against the sear release part 9.
If the trigger piece 11 is now actuated, that is, moved counterclockwise, then first the front stop 35 is vacated and the lost-motion spring 33 is compressed, while the trigger spring 29 holds the sear release part 9 in its location until the rear stop 37 is reached.
Now the trigger piece 11 moves together with the sear release part 9 like the known, single piece trigger 9, 11 and disengages the trigger catch 5 from the trigger sear 7. In the process the disconnector 15 behaves precisely as in the above described case, because the trigger spring 29 loads only the sear release part 11, just as in the described case of the single piece trigger 9, 11.
This trigger spring 29 can be seen more closely from Figures 2 and 3, where its formation as a wire spring can be seen, which acts on both sides of the sear release part 11.
Further the attachment of the transverse axis 27 by means of an overall vertical pin 31 can be seen from Figure 2, under which in the trigger piece part 11 a borehole 41 is formed, in order to give the pin 31 room for disassembly. The lower area of the sear release part and the upper area of the trigger piece are a bit inclined to each other, so that in the case of the sear release part 11 the front stop 35 goes into action when the sear release part is at rest, and the rear stop 37 goes into action when the trigger piece 11 is pulled.
Figure 4 illustrates the function of the mechanism in the case of a disengaged safety roller, and Figure 5 shows the trigger device directly after firing, while the hammer I is just accelerating.
The lost-motion spring 33 can also be mounted accessibly to the extent that it can be effortlessly replaced when for example a softer or harder trigger spring is selected.
The possibility also exists of adjusting the spring action via a screw similar to the lost-motion setting (not shown).
Figure 6 shows a further development of the invention, wherein an adjusting screw spindle 43 is inserted into the trigger piece 11. This screw spindle 43 can be adjusted from below by means of a screw driver and serves the purpose of shortening or lengthening the lost-motion path which the trigger piece part 11 travels relative to the sear release part 9.
Parts 9 and 11 however form a single component in the case of the known trigger device, different than shown in Figure 1, where the inventive two-way trigger is shown.
If the safety roller 25 is turned, as is shown for example in Figures 4 and 5, then the trigger 9, 11 in the case of actuation can carry out a counterclockwise rotary movement until the trigger piece 7 releases the trigger catch 5. This rotary movement is however in the case of the known single piece trigger 9, 11 quite short. At the same time the disconnector nose 17 lies on the hammer I and is pushed back against the spring 23. Now the hammer 1 can move counterclockwise and releases. In the process, the trigger 9, 11 remains in its position.
The release of the hammer 1 discharges a shot, on the basis of which the breech (not shown) is pushed back and the hammer I is cocked again clockwise. In the process the disconnector nose 17 is first pressed against the spring 23 into the longitudinal groove 19 and then engages in the hammer via the disconnector catch 13, said hammer being held by the catch 13 and nose 17.
Printed: 22-10-2008 DESCPAMD PCT/EP 2007/006 781 If the trigger 9, 11 is now released, then the trigger piece 7 presses against the hammer 1 before the disconnector catch 17 is pulled back so far that it releases the disconnector catch 13. The hammer 1 engages a little bit (counterclockwise) forwards and engages with its trigger catch 5 back in the trigger sear 7.
In accordance with the invention, however, as shown the trigger 9, 11 is broken down into two parts, namely a sear release part 9 and a trigger piece 11, which are flexibly connected to each other by a transverse axis 27. A lost-motion spring 33 in the process loads the trigger piece 11 clockwise around the transverse axis 27 until the trigger piece is seated in a front catch 35 against the sear release part 9.
If the trigger piece 11 is now actuated, that is, moved counterclockwise, then first the front stop 35 is vacated and the lost-motion spring 33 is compressed, while the trigger spring 29 holds the sear release part 9 in its location until the rear stop 37 is reached.
Now the trigger piece 11 moves together with the sear release part 9 like the known, single piece trigger 9, 11 and disengages the trigger catch 5 from the trigger sear 7. In the process the disconnector 15 behaves precisely as in the above described case, because the trigger spring 29 loads only the sear release part 11, just as in the described case of the single piece trigger 9, 11.
This trigger spring 29 can be seen more closely from Figures 2 and 3, where its formation as a wire spring can be seen, which acts on both sides of the sear release part 11.
Further the attachment of the transverse axis 27 by means of an overall vertical pin 31 can be seen from Figure 2, under which in the trigger piece part 11 a borehole 41 is formed, in order to give the pin 31 room for disassembly. The lower area of the sear release part and the upper area of the trigger piece are a bit inclined to each other, so that in the case of the sear release part 11 the front stop 35 goes into action when the sear release part is at rest, and the rear stop 37 goes into action when the trigger piece 11 is pulled.
Figure 4 illustrates the function of the mechanism in the case of a disengaged safety roller, and Figure 5 shows the trigger device directly after firing, while the hammer I is just accelerating.
The lost-motion spring 33 can also be mounted accessibly to the extent that it can be effortlessly replaced when for example a softer or harder trigger spring is selected.
The possibility also exists of adjusting the spring action via a screw similar to the lost-motion setting (not shown).
Figure 6 shows a further development of the invention, wherein an adjusting screw spindle 43 is inserted into the trigger piece 11. This screw spindle 43 can be adjusted from below by means of a screw driver and serves the purpose of shortening or lengthening the lost-motion path which the trigger piece part 11 travels relative to the sear release part 9.
Claims (6)
1. A trigger device for a firearm, in particular a self-loading military rifle, especially an attack rifle, having - a trigger piece (11), - a sear release part (9) connected to the trigger piece (11) which detachably engages in a catch (5) of a hammer (1), - at least one trigger spring (29) which acts on the sear release part (9), wherein - a disconnector (15) is pivotable on the sear release part (9), said disconnector detachably engaging in a second catch (13) of the hammer, - the trigger piece (11) is arranged separately from the sear release part (11) between two stops (35, 37), one (35) of which prevents the movement of the trigger piece (11) relative to the sear release part (9) forwards, while the other (37) prevents such movement to the rear, with a short movement of the trigger piece (11) relative to the sear release part (9) being possible between the two stops (35, 37), - a lost motion spring (33) acting on the trigger piece (11) and being preferably arranged between the trigger piece (11) and the sear release part (9), pushing the trigger piece (11) forwards considerably more weakly than does the trigger spring (29), and - a further spring (23) being arranged between the sear release part and disconnector (15).
2. The trigger device according to Claim 1, characterized in that the trigger piece (11) is pivoted around a transverse axis (27) on the sear release part (9).
3. The trigger device according to Claim 2, characterized in that at least one of the stops (35, 37) is constructed as a horizontal area on the trigger piece (9) and/or on the sear release part (11).
