An embodiment of the invention is explained below with reference to the drawings. In the pressure point position they show:

1 shows a section of a hand gun in a sectional view to explain the invention,

Fig. 2 shows the lot with the trigger tongue according to section II in Fig. 1 on an enlarged scale, and

Fig. 3 shows the lot with the adjusting means according to section III in Fig. 1 on an enlarged scale.

The handgun shown in the drawing has a housing made of plastic, with a handle 110 and a locking piece 111, which are held together by a screw 112 that can be screwed in from the magazine shaft 113. Other fasteners are available, as is also known from German Offenlegungsschrift 3 522 155, which, however, cannot be seen in the cutout of the weapon shown.

Only the rearmost part of barrel 114 is shown with the cartridge chamber. The locking piece 115 is guided to and fro and comprises the firing pin 116 with firing pin spring 117. The locking piece 115 has a run-up surface 118 on its rear lower part for rotating the hammer 6 into the tensioned position. Further details of the breech and barrel as well as the housing parts need not be described further here, since they are explained in the aforementioned publication with all details.

According to this exemplary embodiment, the trigger device mainly consists of the trigger tongue 13 on the trigger holder 9, the trigger rod 15 with trigger studs 19, the holding piece 21 for the hammer 6 and the impact rod 7 with the impact spring 39.

The trigger holder 9 is designed as an angle lever which is rotatably mounted on its apex 93. The trigger rod 15 is rotatably attached to the shorter upward leg 92 by means of a trigger rod bolt 16. The longer leg 91 pointing to the left in the drawing has a longitudinal slot 94 and guide surfaces 96 next to this slot 94 for a sliding nut 5.

The trigger tongue 13 is fastened with a trigger screw 14 to a holding plate 10 located under the slot 94. The position of the trigger tongue 13 can thus be displaced with respect to its distance from the handle of the weapon. As clearly shown in FIG. 1, this trigger screw 14 is easily accessible from the outside.

The free end 95 of the longer leg 91 is formed like a pin for fastening one end of a helical spring 34. The second end of this helical spring 34, which acts as a tension spring, is attached to a tension spring bolt 35 in a manner fixed to the housing. As is easy to see, this tension spring produces a fixed counterforce for the preference and serves primarily to reset the trigger rod 15 and the trigger holder 9.

An adjusting piece 3 arranged fixed to the housing is provided with a threaded bore 301 directed approximately perpendicularly against the longer leg 91, and said longer leg 91 has a correspondingly arranged through opening 97. A bushing 36 with an internal and external thread is inserted into the threaded bore 301. A trigger stop screw 37 is screwed through the through opening 97 into the bush 36. The distance of the head of this trigger stop screw 37 from the adjusting piece 3 or from the underside of the bush 36 limits the maximum deflection of the trigger tongue 13. Since this represents a unique setting for a sporting weapon, this screw does not have to be accessible from the outside. The sleeve 36 is adjusted during assembly such that the trigger rod 15 and pawl 192 engage in one another without play when the trigger holder rests on the sleeve 36.

The trigger rod 15 articulated on the shorter leg 92 is at its other end in engagement with a pawl 192 on the trigger lug 19. A trigger rod spring 30 presses the trigger rod 15 against the pawl 192 and thus ensures the engagement.

As usual, the hammer 6 is rotatably supported on a bearing pin 24 fixed to the housing. A beater bar 7, which is rotatably and axially displaceably mounted on a beater bar bearing 38 in the housing, is articulated on the hammer 6 by means of a beater bar bolt 8. The striking spring 37 comprises the striking rod 7 and is supported on the one hand on the striking rod bearing 38 and on the other hand on a shoulder 71 of the striking rod 7 close to the hammer 6.

In addition to the hammer head 62, the hammer 6 also has a second projection, the hammer cam 61. The hammer cam 61 is intended for engagement in the cam recess 211 of a holding piece 21 designed as a one-armed lever. A coil spring 23 between the take-off lug 19 and the holding piece 21 presses it against the hammer 6 and thus supports the engagement of the hammer cam 61 and the cam recess 211 in the tensioned state of the hammer 6.

The holding piece 21 has a latching lug 214 with a latching surface 213 on its flank 212 opposite the cam recess 211. In the tensioned state of the hammer 6, a latching surface 191 of the trigger gallery 19 rests on this latching surface 213. When the hammer 6 is tensioned, the cam 61 presses on the lower nose 215 of the holding piece 21 and pulls it to the left in FIG. 3. The surfaces 191 and 213 thus come to lie on one another. The rotation of the holding piece 21 is supported by the spring 23.

The take-off lug 19 is designed as a three-armed, rotatably mounted lever. A first arm 194 has the pawl 192 and is thus in engagement with the trigger rod 15. The trigger rod 15 is pressed against the pawl 192 by means of the trigger rod spring 30. A second arm 193 carries the trigger 191 mentioned above. The adjusting means act against the third arm. All three arms 192, 194, 195 are at least approximately 90 ° rotated relative to each other.

A stud stop screw 25 is screwed onto the last-mentioned third arm 195, which extends beyond the axis of rotation 20 in the axial direction of the first arm 194. The head 252 of the screw 25 lies in a recess 254 of the housing 1 and, with the stop surface 253 of this recess 254, fixes the rest position of the take-off lug 19.

In addition to this limitation of the preferred travel, from which the other-acting limitation, as explained above, is brought about by the bush 36 and the trigger stop screw 37, a further adjusting means for changing the preferred force acts on this arm 195. For this purpose, a threaded bore 271 for a stud spring screw 27 is arranged in the housing 1. The stud spring 26 is inserted into a guide bore 196 in the trigger stud arm 195 and is guided on the other side by a guide pin 272 on the stud spring screw 27. Viewed from its effect, this stud spring 26 lies parallel to the mentioned tension spring 34 with a fixed predetermined spring force. The preferred force can thus be selected from a minimum determined by the tension spring 34 to a force given by tensioning the stud spring 26.

Another adjustment device allows changing the pressure point force and the path in the pressure point. For this purpose, a hollow screw 281 is screwed into the housing 1 below the stud spring screw 27. Centrally in this is an axial bore 285 as a guide for one

axially movable pressure pin 284 arranged. The bolt \ is under the pressure of a helical spring 283, the force of which can be adjusted with a pressure screw 282 screwed into the hollow screw 281. The displacement in the pressure point can be adjusted by adjusting the hollow screw 281, and the pressure point force can be adjusted with the spring 283 and the screw 282.

Finally, a fuse 29, 40 is installed in the housing 1, with which a movement of the take-off lug 19 can be prevented, as a result of which the triggering of the hammer 6 in the tensioned state can be prevented. A rotatable securing bolt 40 has two locking recesses 401 and 402 and, in addition, a recess 403 for the free movement of the free end 197 of the take-off lug 19. A helical spring 291 and a ball 292 are axially movable in a hollow screw 29 which is screwed into the housing supported. The ball 292 engages in a respective recess 401, 402 in order to clearly define the two positions “secured” and “ready to fire”. In the “secured” position, the third arm 195 rests on the securing bolt 40 and the third arm 195 cannot be moved as a result.

10th

All settings for the preferred force, preferred path, pressure point force and path in the pressure point can be easily adjusted on the handle on the rear of the weapon.
