Description:
BACKGROUND OF THE INVENTION 
     The invention relates to a trigger device for a semi-automatic handgun, comprising a locking element swivel-mounted around a first axis having an effect on a trigger element via a locking face and a shot limitation device, which has a control element with at least two locking positions for a locking face or control face defining a pawl around a second axis. 
     From EP 0 362 188 A2, a trigger mechanism for automatic handguns is known, which allows continuous fire with a certain number of rounds. The number of rounds is defined by the shot limitation device. It is virtually impossible to deliberately interrupt or dose the number of rounds before firing the total predefined number of rounds within a burst. 
     Specification DE 1 129 873 B describes a shot limiter for automatic weapons, which is actuated by the movement of the lock and allows a geared member to be advanced by one cog for each shot, which causes an interruption after a certain number of shooting actions, by triggering a mechanical connection in the trigger mechanism. An actuating lever activated by the lock is designed as an integral element and guided through guideways and return elements in such a way that it switches the cogs of the geared member with its catch due to a compound pushing and pivoting motion. Furthermore, a latch is provided, which retains the geared member, which is under the influence of an elastic member, after each shifting of the same. After the trigger has been engaged, a pre-set number of rounds is released completely automatically, wherein the shot sequence cannot be interrupted by the shooter. 
     DE 655 334 C describes a device for automatic interruption of the free-flow fire of automatic weapons, wherein a certain number of rounds can be pre-set before triggering a volley of shots. In addition, there is just one single pressure point for each shot sequence, wherein the predefined number of consecutive shots is triggered after pressing the pressure point without the shooter having the chance of an interruption to the shots. 
     The described devices are well-known multi-trigger systems, as constitutes a three-shot automatic for example. The multi-triggers are a trigger system, with which an adjustable or predefined shot rate, for example a three-shot automatic—three shots consecutively—is automatically discharged by the system. The time between the first, second and third shot is identical and predefined by the trigger system. To trigger this procedure, one single pressure point is overcome, whereupon three or more shots are fired. This procedure cannot be interrupted as it is a fully-automated process and, consequently, a fully-automated weapon system. 
     SUMMARY OF THE INVENTION 
     The object of the invention is to provide a trigger device for handguns, which allows a limited and precisely metered firing for rapid-fire sequences. 
     This is achieved in such a way that the control element is formed by a sear arranged in the path of action between a trigger and the trigger element, which exerts an influence on the trigger element through the pawl and the locking element, wherein the second axis is preferably spaced from the first axis, wherein the pawl is swivel-mounted on the locking element around the second axis. 
     In doing so, a pressure point of the trigger is assigned to each shot, so that the shooter can interrupt the shot sequence at any time between the two pressure points. This allows the shooter to have precisely metered firing with quick-fire sequences, wherein the firing can be deliberately interrupted by the shooter within a shot sequence at any time. 
     The trigger element can be formed by a striker or a firing pin holding element. 
     It is particularly advantageous if the pawl is designed as a two-armed lever, whose first lever arm forms an initial contact face cooperating with the control face of the control element and the second lever arm forms a second contact face cooperating with a control face of the trigger element. 
     The sear can be formed operatively connected with the trigger and separate to this. Preferably the sear is operatively connected with the trigger through a transmission element that is preferably designed as a single-sided transmission lever, wherein the trigger can be operatively connected with the transmission element via a pressure nose. Through the dimensioning of the lever arms of the transmission lever and the pressure nose, the trigger forces and trigger points can be designed very flexibly. As an alternative to a multi-part design, it is also possible to design the sear as a single piece with the trigger. This makes it possible to keep the number of parts very low. 
     For example, the sear can be slidably mounted in a housing. The housing can be the actual housing of the handgun, a gripstock or the frame of an exchangeable module for the handgun. However, it is particularly advantageous if the sear is swivel-mounted in a housing, wherein the trigger element and the sear are preferably swivel-mounted around the same pivot point. This also makes it possible to retrospectively install and retrofit the trigger device in accordance with the invention in established handguns. 
     A very compact structure can be achieved if the locking element is swivel-mounted on the sear. However, it is also conceivable that the locking element is swivel-mounted in the housing. 
     The control element preferably has at least one toothed segment with at least two locking teeth defining the locking positions. The pawl latches into one of the locking teeth when the trigger element moves. Alternatively, it can also be provided that the control element has a sliding guide with at least two locking deflectors defining the locking positions, wherein a sliding block is preferably assembled on the first lever arm, which is forcibly guided in the sliding guide. 
     To use the available space optimally, it can be advantageous if the sear is designed to have multiple parts, wherein the sear preferably has a first toothed segment non-rotatably connected with the trigger and a second toothed segment non-rotatably connected with the control element, which is in tooth meshing with the first toothed segment.

     DETAILED DESCRIPTION OF EMBODIMENTS 
     Functionally-identical elements are labeled in the embodiments with the same reference signs. 
     The trigger devices  10  for a handgun shown in the embodiments each have a trigger element  1 , a locking element  2 , a pawl  3 , a sear  4  and a trigger  5 . A housing is labeled using reference numeral  6 . This can be the housing of the handgun, a gripstock or the frame of a replaceable module for the trigger device  10 . In the latter case, the module for the trigger device can be used interchangeably in the gripstock of the handgun. In the embodiments, the trigger element  1  is formed by a striker swivel-mounted around a pivot point A in housing  6 , which is pre-stressed counterclockwise by a spring (not shown in closer detail), as is implied by arrow F A . The trigger  5  is swivel-mounted around a pivot point C in housing  6  and pre-stressed in a clockwise direction by a spring force F C . 
     With the described trigger devices  10 , semiautomatic fire and quick-fire sequences (QSF) can be realized, and possibly also sustained fire (fully automatic). The setup of these types of firing is not part of the invention and is therefore not explained in further detail. In the following, only the quick-fire sequence will be described. 
     To realize the quick-fire sequence function, the trigger device  10  has a shot limitation device  20 , which is formed by a control element  21 , the locking element  2  swivel-mounted around a first axis B and the pawl  3 . The locking and control faces AS 1 , AS 2 , AS 3  of the control element  21  define at least two locking positions a, b, c for the pawl  3 . Each locking position a, b, c defines a pressure point for trigger  5 . During a trigger movement of the trigger  5 , the locking positions a, b, c defined by the locking or control faces AS 1 , AS 2 , AS 3  result in several pressure points. 
     The locking or control faces AS 1 , AS 2 , AS 3  of the control element  21  can be formed by locking teeth  71 ,  72 ,  73  of a toothed segment  7  ( FIG. 1  to  FIG. 6 ) or sliding deflectors  81 ,  82  of a sliding guide  8  of sear  4  ( FIG. 7 ). The locking element  2  is prestressed in a counterclockwise direction into that in  FIG. 5  to  FIG. 7  by a spring force F B  in  FIGS. 1 to 4 . Due to the spring load, self-locking occurs between trigger element  1  and locking element  2 . The pawl  3  engaging in the locking positions a, b, c of the locking or control faces AS 1 , AS 2 , AS 3  is designed as a two-sided lever with a first lever arm  31  and a second lever arm  32  and swivel-mounted in the locking element  2  around a second axis B 1 . When pivoting the locking element  2 , the second axis B 1  experiences a rotary motion around the first axis B. 
     For the quick-fire function, the following locking faces are important: 
     SK 1  First contact face of pawl  3   
     SK 2  Second contact face of pawl  3   
     AS 1 , AS 2 , AS 3  Locking or control faces of locking teeth  71 ,  72 ,  73  or the sliding deflectors  81 ,  82  of sear  4   
     SP Control face of trigger element  1   
     S Locking face of trigger element  1   
     SN Locking face of locking element  2   
     Furthermore, the contact faces between trigger  5  and sear  4  are labeled with AS or AH. 
     Arrow P highlights the direction of shooting of the handgun. 
     In the following, the trigger process will be explained on the basis of the first embodiment shown in  FIG. 1  to  FIG. 4 .  FIGS. 1 to 4  show various stages of the trigger process. 
     In this first embodiment, the sear  4  is formed as a displaceably mounted slider or as a rod in housing  6 . The first axis B for the swivel-mounted bearing of locking element  2  is designed to be fixed within the housing. 
     I—Standby Mode ( FIG. 1 ). 
     The trigger element  1  is held in the fully-tensioned position by locking element  2 . The trigger element  1  is in its tensioned standby position, wherein the locking faces S or SN of the trigger element  1  and the locking element  2  are in contact. The spring-loaded sear  4  is in the far-left standby position of  FIG. 1 . The spring-loaded trigger  5  is in its standby position. 
     II—Pressure Point ( FIG. 2 ) 
     The shot-triggering procedure begins: 
     The trigger  5  is moved by the shooter in the direction x against the spring force F C  in  FIG. 1 , wherein it is pivoted counterclockwise around pivot point C. The trigger  5  makes contact with the contact face AH on the contact face AS of sear  4 . The trigger  5  and sear  4  begin to move together in the direction x. In further consequence, the locking face AS 1  of the first tooth  71  meets the first contact face SK 1  of the pawl  3 . The pawl  3  can be spring-loaded in the direction of control faces AS 1 , AS 2 , AS 3  (i.e. in a counterclockwise direction in  FIG. 1  to  FIG. 4 ). The locking element  2  is moved from its standby position, in a counterclockwise direction. Due to the shape of the corresponding locking faces AS 1  and SK 1 , a rotary movement of the locking element  2  occurs around the first axis B. 
     III—Trigger Moment ( FIG. 3 ) 
     The locking element  2  is rotated around the first axis B in a counterclockwise direction via the sear  4  due to the continuous force effect of the shooter on the trigger  5 , wherein the locking face S of the locking element  2  slides radially to the outside along the locking face SN of the latching recess  9  of the trigger element  1  in an counterclockwise direction in relation to the first axis B, until the locking faces S and SN lose their mutual contact (see  FIG. 3 ). The spring-loaded trigger element  1  now begins to turn in a counterclockwise direction through the spring force F A  and subsequently encounters the firing pin (not shown), which executes the energy transfer on the percussion cap. 
     IV—Triggering for the 2nd or 3rd Shot ( FIG. 4 ) 
     As part of the rotary movement of the trigger element  1  around the pivot point A, the control face SP of trigger element  1  comes into contact with the second contact face SK 2  of pawl  3 . The pawl  3  begins to rotate around the second axis B 1  in the clockwise direction, wherein the first contact face SK 1  of pawl  3  slides along to the locking face AS 1  of the first locking tooth  71 , until it is released. Due to a backward movement of a breech (not shown) in X direction, the trigger element  1  is rotated clockwise around pivot point A against the spring force F A . Due to the spring load of locking element  2 , this is pressed against the trigger element  1  in the clockwise direction. If the movement of the trigger element  1  clockwise exceeds the locking face SN of locking element  2 , the locking element  2  pivots back into the latching recess  9 . As soon as the breech moves in the opposite direction in the direction of the barrel, the trigger element  1  is moved in the counterclockwise direction by the spring force F A , wherein the locking faces S and SN of locking element  2  or of trigger element  1  come back to be positioned on top of each other. The trigger element  1  is now back in its tensioned standby position. 
     If the shooter operating the handgun exerts another tightening on the trigger  5 , then the sear  4  is shifted further in the X direction, wherein the first contact face SK 1  makes contact with the locking face AS 2  of the second tooth  72  and the locking element  2  is rotated by the sear  4  around the first axis B in a counterclockwise direction and is moved radially outwardly from the latching recess  9 , so that the released trigger element  1  is rotated by the spring force F A  in a counterclockwise direction and in further consequence the energy transfer on the percussion cap can be executed for the second shot by hitting the firing pin. In a similar way, after the end of the cycles for the first and second shots, the cycle for the third shot can be initiated through the locking face AS 3  of the third locking tooth  73 . 
     Should the trigger process be interrupted by the shooter, wherein the trigger  5  remains in its position or moves around the pivot point C in a counterclockwise direction in the direction of its standby position, then the sear  4  is returned to its standby position by spring force, wherein the pawl  3  is force-controlled due to its design and rotated in the clockwise direction around pivot point B 1  and slides over the locking faces AS 3  to AS 1 . 
       FIG. 5  shows a second embodiment of a trigger device  10 , which is different to the first embodiment in  FIG. 1  to  FIG. 4  in that the sear  4  now forms a housing for the locking element  2 —the locking element  2  is now pivot-mounted around the first axis B directly in sear  4 . The sear  4  itself can be swivel-mounted around pivot point A. This makes it possible to retrofit the entire trigger device  10  without further reconfiguration work in existing handguns. Furthermore, this embodiment is different to that of  FIG. 1  to  FIG. 4  in that the control face SP and locking face S of trigger element  1  can coincide. The sear  4  can be directly controlled by trigger  5 . It is also possible to mount the trigger  5  directly on sear  4  or to design this to be integral therewith. 
     By contrast,  FIG. 6  shows another embodiment, which is different to that shown in  FIG. 5  in that the triggering of the sear  4  occurs by the trigger through a transmission element  11 , which is formed here as a one-sided transmission lever. Through the appropriate dimensioning of the lengths of the lever arms of the transmission lever, transmissions or reductions and consequently different angles of rotation of the trigger  5  or the sear  4  can be realized. The necessary trigger forces can be adjusted through the size and position of an actuating nose  5   a  provided on the trigger  5 . The actuating nose  5   a  can also be designed as a separate element, wherein different leverage forces and consequently different trigger resistances can be realized through the provision of different mounting points. 
     Furthermore,  FIG. 7  shows an embodiment, in which the control element  21  of the shot limitation device  20  has a sliding guide  8  with at least two sliding deflectors  81 ,  82  defining the locking positions a, b. Each of the locking positions a, b defines the pressure point for a single firing during the quick-fire function within a trigger movement of the trigger  5 . In the example shown in  FIG. 7 , two cartridges per trigger movement would be ignited with the quick-fire function, as two control faces AS 1 , AS 2  are available which extend upwardly in an angled manner. On the first lever arm of the pawl  3 , a sliding block  3   a  is fitted, which is forcibly guided into the sliding guide  8 . The sliding block  3   a  can be fixed or rotatably—for example designed as a roller—connected with the pawl  3 . Upon pressing the trigger  5 , the sear  4  begins to rotate in a clockwise direction due to the direct effect of the trigger  5  as described on the basis of  FIG. 5  on the sear  4  or the indirect effect of the trigger  5  as described in  FIG. 6  via the transmission element  11 . The sliding block  3   a,  a component of the pawl  3 , moves along the sliding guide  8  until the sliding block  3   a  meets the first inclined control face AS 1 ; on the basis of the work angle of the first control face AS 1 , static friction occurs between the sliding block  3   a  and the control face AS 1 , whereby the locking element  2  begins to rotate around the pivot point B fixed to the housing through the continuous application of force. The pivot point B 1  is—as with the previously described embodiments—connected with the locking element  2 . The pressure point that is typical for the weapon occurs when the sliding block  3   a  strikes the first sliding deflector  81 . After the trigger element  1  has been released from the locking element  2 , the trigger element  1  moves in a clockwise direction. 
     In the contact range with the pawl  3 , the trigger element  1  has a recess  1   a,  with which the pawl  3  is sometimes forcibly triggered. Due to the application of force of the recess is of the trigger element  1 , the first lever arm  31  of the pawl  3  moves “upwards” in the direction of the trigger element  1 , i.e. counterclockwise in  FIG. 7 . The trigger element  1  is moved backwards into the starting position after triggering the first shot by the breech (not shown) of the handgun. Due to the continuous application of force on the trigger  5  and the subsequent rotary movement of the sear  4 , the pawl  3  moves “downwards” in a clockwise direction. 
     In the lower area of the sliding guide  8 —shown in  FIG. 7 —the sliding block  3   a  meets the second upwardly inclined control face AS 2 —from this point the described process is repeated. 
     If the triggering process is interrupted and the trigger  5  is disengaged, the sliding block  3   a  moves back along the sliding guide  8  into its starting position. This is possible as the trigger element  1  in the lower section, in  FIG. 7  left of recess  1   a,  is released. As a result, there is only a one-sided forced control of pawl  3 . A movement of the pawl  3  counterclockwise at the exact interruption of the shot sequence is possible during a trigger movement in any pressure point. 
       FIG. 8  to  FIG. 31  show a trigger device  10  in accordance with the invention in a fifth embodiment, wherein the sear  4  is designed to consist of multiple parts and has two toothed segments  4   a,    4   b  with meshing teeth. The first toothed segment  4   a  is non-rotatably connected with the trigger  5 . The second toothed segment  4   b  is non-rotatably connected with the control element  21 . The first axis B for the rotary movement of locking element  2  rotary axis B and pivot point C of trigger  5  coincide. The second axis B 1  for the swivel movement of the pawl  3  is found on the locking element  2  at a distance from the first axis B. The pawl  3  is designed as a single-armed lever and is prestressed by the spring  33  in the direction of the control element  21 . The control element  21  also has several teeth  71 ,  72 ,  73  in this embodiment, which interact with the pawl  3 . 
     In  FIG. 11  to  FIG. 31 , the various phases I—VII of the trigger are shown. 
     I—Starting Position ( FIG. 11  to  FIG. 13 ) 
     The trigger element  1  is held in the fully-tensioned position by locking element  2 . The trigger element  1  is in its tensioned standby position, wherein the locking faces S or SN of the trigger element  1  and the locking element  2  are in contact. The sear  4  and the spring-loaded trigger  5  are in their standby position. 
     II—Firing of 1st Tooth ( FIG. 14  to  FIG. 16 ) 
     The shot-triggering procedure begins: 
     The trigger  5  is moved by the shooter in the direction x against the spring force F C  in  FIG. 1 , wherein it is pivoted clockwise around pivot point C. The trigger  5  is non-rotatably connected with the first toothed segment  4   a  and begins to move against the spring resetting force F C  around the first axis B together with said segment. In further consequence, the locking face AS 1  of the first tooth  71  of the control element  21  meets the first contact face SK 1  of pawl  3 . The locking element  2  is moved from its standby position in a clockwise direction in  FIG. 14  to  FIG. 16 . Due to the shape of the corresponding locking faces AS 1  and SK 1 , a rotary movement of the locking element  2  occurs around the first axis B. 
     III—Fired 1st Tooth ( FIG. 17  to  FIG. 19 ) 
     The locking element  2  is rotated around the first axis B in a clockwise direction via the sear  4  due to the continuous force effect of the shooter on the trigger  5 , wherein the locking face S of the locking element  2  slides radially to the outside along the locking face SN of the latching recess  9  of the trigger element  1  in a clockwise direction in relation to the first axis B, until the locking faces S and SN lose their mutual contact (see  FIG. 17  to  FIG. 19 ). The trigger element  1  stressed by the spring  34  now begins to turn around pivot point A in a clockwise direction through the spring force F A  of spring  34  and subsequently meets the firing pin (not shown), which executes the energy transfer on the percussion cap. 
     The pawl  3  lies flat on trigger element  1  or is supported thereon. 
     If one considers the contact surface  1   b  of the trigger element  1  for the pawl  3  in the “trigger element tensioned” state ( FIG. 14  to  FIG. 16 ) and “trigger element fired” ( FIG. 17  to  FIG. 19 ), it can be determined that the radius of the contact surface  1   b  changes from “tensioned” to “fired”—i.e. becomes larger. This leads to the consequence that the pawl  3  is rotated somewhat counterclockwise, with a shot direction towards the right. This is technically necessary as coordination between the faces of locking element  2 —trigger element  1  and pawl  3 —control element  21  is difficult to coordinate in terms of time or mechanics and a “tilting” of the pawl  3  protects the components and reduces frictional force. 
     IV—Firing of 2nd Tooth ( FIG. 20  to  FIG. 22 ) 
     Due to a backward movement of a breech (not shown) in X direction, the trigger element  1  is rotated counterclockwise around pivot point A against the spring force F A . Due to the spring load of locking element  2 , it is pressed against the trigger element  1  in the clockwise direction. If the movement of the trigger element  1  counterclockwise exceeds the locking face S of locking element  2 , the locking element  2  pivots back into the latching recess  9 —the locking face S of locking element  2  comes back into contact with the locking face SN of trigger element  1 . As soon as the breech moves in the opposite direction in the direction of the barrel, the trigger element  1  is moved in the clockwise direction by the spring force F A , wherein the locking faces S and SN of locking element  2  or of trigger element  1  come back to be positioned on top of each other. The trigger element  1  is now back in its tensioned standby position. 
     The trigger  5  is moved by the shooter further in the direction x against the spring force F C , wherein it is pivoted clockwise around pivot point C. The trigger  5  begins to move against the spring resetting force F C  around the first axis B together with the first toothed segment  4   a.  In further consequence, the locking face AS 2  of the second tooth  72  of the control element  21  encounters the first contact face SK 1  of pawl  3 . The locking element  2  is moved from its standby position, in a clockwise direction in  FIG. 20  to  FIG. 22 . Due to the shape of the corresponding locking faces AS 2  and SK 1 , a rotary movement of the locking element  2  occurs around the first axis B. 
     V—Fired 2nd Tooth ( FIG. 23  to  FIG. 25 ) 
     The locking element  2  is rotated around the first axis B in a clockwise direction via the sear  4  due to the continuous force effect of the shooter on the trigger  5 , wherein the locking face S of the locking element  2  slides radially to the outside along locking face SN of the latching recess  9  of the trigger element  1  in a clockwise direction in relation to the first axis B, until the locking faces S and SN lose their mutual contact (see  FIG. 23  to  FIG. 25 ). The spring-loaded trigger element  1  now begins to turn around pivot point A in a clockwise direction through the spring force F A  and subsequently meets the firing pin (not shown) again, which executes the energy transfer on the percussion cap. 
     VI—Firing of 3rd Tooth ( FIG. 26  to  FIG. 28 ) 
     Due to the backward movement of the breech in the X direction, the trigger element  1  is rotated counterclockwise around pivot point A against the spring force F A . Due to the spring load of locking element  2 , it is pressed against the trigger element  1  in the clockwise direction. If the movement of the trigger element  1  counterclockwise exceeds the locking face S of locking element  2 , the locking element  2  pivots back into the latching recess  9 —the locking face S of locking element  2  comes back into contact with the locking face SN of trigger element  1 . As soon as the breech moves in the opposite direction in the direction of the barrel, the trigger element  1  is moved in the clockwise direction by the spring force F A , wherein the locking faces S and SN of locking element  2  or of trigger element  1  come back to be positioned on top of each other. The trigger element  1  is now back in its tensioned standby position. 
     The trigger  5  is moved by the shooter further in the direction x against the spring force F C , wherein it is pivoted clockwise around pivot point C. The trigger  5  begins to move against the spring resetting force F C  around the first axis B together with the first toothed segment  4   a.  In further consequence, the locking face AS 3  of the third tooth  73  of the control element  21  meets the first contact face SK 1  of pawl  3 . The locking element  2  is moved from its standby position in a clockwise direction in  FIG. 26  to  FIG. 28 . Due to the shape of the corresponding locking faces AS 3  and SK 1 , a rotary movement of the locking element  2  occurs around the first axis B. 
     VII—Fired 3rd Tooth ( FIG. 29  to  FIG. 31 ) 
     The locking element  2  is rotated around the first axis B in a clockwise direction via the sear  4  due to the continuous force effect of the shooter on the trigger  5 , wherein the locking face S of the locking element  2  slides radially to the outside along the locking face SN of the latching recess  9  of the trigger element  1  in a clockwise direction in relation to the first axis B, until the locking faces S and SN lose their mutual contact (see  FIG. 23  to  FIG. 25 ). The spring-loaded trigger element  1  now begins to turn around pivot point A in a clockwise direction through the spring force F A  and subsequently meets the firing pin (not shown) again, which executes the energy transfer on the percussion cap. 
     Should the trigger process be interrupted by the shooter, wherein the trigger  5  remains in its position or moves around the pivot point C counterclockwise in the direction of its standby position, then the sear  4  is returned to its standby position by spring force, wherein the pawl  3  is force-controlled due to its design and rotated in the clockwise direction around pivot point B 1  and slides over the locking faces AS 3  to AS 1 .
