DETAILED DESCRIPTION OF EMBODIMENTS

(33) Functionally-identical elements are labeled in the embodiments with the same reference signs.

(34) 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.sub.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.sub.C.

(35) 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.

(36) 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 AS1, AS2, AS3 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 AS1, AS2, AS3 result in several pressure points.

(37) The locking or control faces AS1, AS2, AS3 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.sub.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 AS1, AS2, AS3 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 B1. When pivoting the locking element 2, the second axis B1 experiences a rotary motion around the first axis B.

(38) For the quick-fire function, the following locking faces are important:

(39) SK1 First contact face of pawl 3

(40) SK2 Second contact face of pawl 3

(41) AS1, AS2, AS3 Locking or control faces of locking teeth 71, 72, 73 or the sliding deflectors 81, 82 of sear 4

(42) SP Control face of trigger element 1

(43) S Locking face of trigger element 1

(44) SN Locking face of locking element 2

(45) Furthermore, the contact faces between trigger 5 and sear 4 are labeled with AS or AH.

(46) Arrow P highlights the direction of shooting of the handgun.

(47) 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.

(48) 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.

(49) IStandby Mode (FIG. 1).

(50) 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.

(51) IIPressure Point (FIG. 2)

(52) The shot-triggering procedure begins:

(53) The trigger 5 is moved by the shooter in the direction x against the spring force F.sub.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 AS1 of the first tooth 71 meets the first contact face SK1 of the pawl 3. The pawl 3 can be spring-loaded in the direction of control faces AS1, AS2, AS3 (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 AS1 and SK1, a rotary movement of the locking element 2 occurs around the first axis B.

(54) IIITrigger Moment (FIG. 3)

(55) 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.sub.A and subsequently encounters the firing pin (not shown), which executes the energy transfer on the percussion cap.

(56) IVTriggering for the 2nd or 3rd Shot (FIG. 4)

(57) 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 SK2 of pawl 3. The pawl 3 begins to rotate around the second axis B1 in the clockwise direction, wherein the first contact face SK1 of pawl 3 slides along to the locking face AS1 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.sub.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.sub.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.

(58) 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 SK1 makes contact with the locking face AS2 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.sub.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 AS3 of the third locking tooth 73.

(59) 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 B1 and slides over the locking faces AS3 to AS1.

(60) 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 2the 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.

(61) 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 5a provided on the trigger 5. The actuating nose 5a 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.

(62) 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 AS1, AS2 are available which extend upwardly in an angled manner. On the first lever arm of the pawl 3, a sliding block 3a is fitted, which is forcibly guided into the sliding guide 8. The sliding block 3a can be fixed or rotatablyfor example designed as a rollerconnected 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 3a, a component of the pawl 3, moves along the sliding guide 8 until the sliding block 3a meets the first inclined control face AS1; on the basis of the work angle of the first control face AS1, static friction occurs between the sliding block 3a and the control face AS1, 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 B1 isas with the previously described embodimentsconnected with the locking element 2. The pressure point that is typical for the weapon occurs when the sliding block 3a 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.

(63) In the contact range with the pawl 3, the trigger element 1 has a recess 1a, 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.

(64) In the lower area of the sliding guide 8shown in FIG. 7the sliding block 3a meets the second upwardly inclined control face AS2from this point the described process is repeated.

(65) If the triggering process is interrupted and the trigger 5 is disengaged, the sliding block 3a 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 1a, 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.

(66) 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 4a, 4b with meshing teeth. The first toothed segment 4a is non-rotatably connected with the trigger 5. The second toothed segment 4b 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 B1 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.

(67) In FIG. 11 to FIG. 31, the various phases IVII of the trigger are shown.

(68) IStarting Position (FIG. 11 to FIG. 13)

(69) 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.

(70) IIFiring of 1st Tooth (FIG. 14 to FIG. 16)

(71) The shot-triggering procedure begins:

(72) The trigger 5 is moved by the shooter in the direction x against the spring force F.sub.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 4a and begins to move against the spring resetting force F.sub.C around the first axis B together with said segment. In further consequence, the locking face AS1 of the first tooth 71 of the control element 21 meets the first contact face SK1 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 AS1 and SK1, a rotary movement of the locking element 2 occurs around the first axis B.

(73) IIIFired 1st Tooth (FIG. 17 to FIG. 19)

(74) 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.sub.A of spring 34 and subsequently meets the firing pin (not shown), which executes the energy transfer on the percussion cap.

(75) The pawl 3 lies flat on trigger element 1 or is supported thereon.

(76) If one considers the contact surface 1b 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 1b changes from tensioned to firedi.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 2trigger element 1 and pawl 3control 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.

(77) IVFiring of 2nd Tooth (FIG. 20 to FIG. 22)

(78) 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.sub.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 9the 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.sub.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.

(79) The trigger 5 is moved by the shooter further in the direction x against the spring force F.sub.C, wherein it is pivoted clockwise around pivot point C. The trigger 5 begins to move against the spring resetting force F.sub.C around the first axis B together with the first toothed segment 4a. In further consequence, the locking face AS2 of the second tooth 72 of the control element 21 encounters the first contact face SK1 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 AS2 and SK1, a rotary movement of the locking element 2 occurs around the first axis B.

(80) VFired 2nd Tooth (FIG. 23 to FIG. 25)

(81) 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.sub.A and subsequently meets the firing pin (not shown) again, which executes the energy transfer on the percussion cap.

(82) VIFiring of 3rd Tooth (FIG. 26 to FIG. 28)

(83) 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.sub.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 9the 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.sub.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.

(84) The trigger 5 is moved by the shooter further in the direction x against the spring force F.sub.C, wherein it is pivoted clockwise around pivot point C. The trigger 5 begins to move against the spring resetting force F.sub.C around the first axis B together with the first toothed segment 4a. In further consequence, the locking face AS3 of the third tooth 73 of the control element 21 meets the first contact face SK1 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 AS3 and SK1, a rotary movement of the locking element 2 occurs around the first axis B.

(85) VIIFired 3rd Tooth (FIG. 29 to FIG. 31)

(86) 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.sub.A and subsequently meets the firing pin (not shown) again, which executes the energy transfer on the percussion cap.

(87) 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 B1 and slides over the locking faces AS3 to AS1.
