DETAILED DESCRIPTION

(8) Right, left, forward and backward are as seen in the direction of firing and defined as such.

(9) Represented in the figures is a weapon 100, with a breech 1 or breech head, also known as a breech bolt. The feeding of the breech 1 takes place for example by way of a control carriage 2, which encloses a weapon housing 3 of the weapon 100, preferably in a U-shaped manner. Controlled with this control carriage 2 is a locking latch 4, here a falling-block action, which locks the breech 1 in the firing position. Delivered to the breech 1 in the the rear position of the breech 1 in the weapon 100 is an ammunition 5, which during the forward movement is introduced into a cartridge chamber 6 of the weapon 100.

(10) FIG. 2 shows the breech 1 forward, unlocked. The main components involved in firing a shot from the weapon 100 are in this case a control rocker 7, an elevator 8, a trigger 9 and also a catching pawl 10. The locking latch 4 is coupled with the control rocker 7 by way of a pin 11. Functionally connected to this control rocker 7 is the elevator 8, which with its claws 8.1 engages a first firing pin safety device 12, which lies against a firing pin 13 of the weapon 100 and can be pivoted by the elevator 8. The firing pin 13 comprises a firing pin spring 13.2, which must be tensioned. The firing pin safety device 12 preferably acts on the firing pin 13 before a spring chamber 13.3. For this purpose, the firing pin 13 may have at this point a clearance 13.4, through which the safety device 12 can lie against the firing pin 13. The trigger 9 acts with its catching edge 9.1 against a catching edge 10.1 of the catching pawl 10. The catching pawl 10 is blocked by the trigger 9 as long as the latter engages with its catching edge 9.1 under the catching edge 10.1 of the catching pawl 10. The catching pawl 10 is carried by a spring 9.2 of the trigger 9. The catching pawl 10 is laid before a nose 13.1 of the firing pin 13 and in this position prevents the triggering of the firing pin 13. The catching pawl 10 is (pre)tensioned by way of a spring 9.2 of the trigger 9.

(11) The firing pin 13 comprises a firing pin spring 13.2, which is tensioned by a cocking rocker 14 in interaction with a cocking pushrod 15 during the advancement of the breech 1. The cocking rocker 14 may have an outer contour similar to a heart shape. The cocking rocker 14 by means of a pin 14.1, which forms a cocking pin and is pivotable about a fixed pivot point 14.2. This pivot point 14.2 is located in the lower heart contour, while the pin 14.1 is located in the right side of the heart contour. The pin 14.1 itself is controlled in a cocking cam 16 of a cocking slide 17 along the latter, the cocking rocker 14 being moved about the lower pivot point 14.2. The left side of the heart contour thereby presses onto the cocking pushrod 15 of the firing pin spring 13.2. The firing pin 13 is held in its position by the catching pawl 10, while the cocking pushrod 15 tensions the firing pin spring 13.2 during the advancement of the control slide 2. The safety device 12 releases the firing pin 13 parallel to the locking. The cocking slide 17 is connected to the control slide 2 in such a way that this control slide 2 carries the cocking slide 17 along with it during the advancement of the breech and the return of the breech.

(12) The way in which the firing of a shot functions is to be explained in more detail on the basis of the figures.

(13) The breech 1 is guided from its rear, deactivated position into its front locked position. In its front deactivated position, the control slide 2 runs further. As a result, the pin 11 is transferred in the upward direction in a first front (lower) control cam 2.1 of the control slide 2. With the pin 11, the locking latch 4 is also displaced upward, the breech 1 locked. Combined with this movement, an adjustment of the control rocker 7 takes place in such a way that it pulls the elevator 8 downward. The elevator 8 for its part guides the safety device 12 downward, the latter preferably performing a pivoting movement. The safety device 12 is transferred by the side pins 12.1 of the safety device 12 that engage in the claw 8.1 from the securing position into a triggering position after locking of the breech 1. The safety device 12 is disengaged. The trigger 9 still blocks the catching pawl 10.

(14) It should be mentioned for the sake of completeness that these side pins 12.1 are forcibly guided in guides of the weapon housing during the moving of the breech 1, in order that they act steadily and continuously on the firing pin 13, so that the safety device 12 is engaged during the transport of the breech 1.

(15) In a rear further control cam 2.2 of the control carriage or control slide 2, a further firing pin safety device 18 is guided. This second firing pin safety device 18 may be a connecting rod, which engages in a clearance 1.1 of the breech 1 and in a clearance 13.5 of the firing pin 13. During the forward travel, this connecting rod 18 is retracted from the two clearances 1.1, 13.5 and releases the firing pin 13 after deactivation of the breech 1, and passes on the holding function to the catching pawl 10.

(16) As already mentioned, in the embodiment described the cocking slide 17 is carried along by the control slide 2. Preferably whenever the breech 1 is deactivated and the control slide 2 still runs with the cocking slide 17, the firing pin spring 13.2 is still tensioned, as described.

(17) A slope or ramp 19 on the cocking slide 2 is responsible for the actual firing of a shot. The ramp 19 determines the triggering time. The later the ramp 19 meets the trigger 9, the later a shot is fired. The ramp 19 presses the trigger 9 upwardly away by means of a roller 20. The catching edge 9.1 of the trigger 9 is pressed by the catching edge 10.1 of the catching pawl 10 and releases the catching edge 10.1 of the catching pawl 10. As a result of the spring pretensioning of the catching pawl 10, the latter slides away and for its part releases the nose 13.1 of the firing pin 13. This firing pin 13, then unsecured in this position, moves forward under spring force of the firing pin spring 13.2 and strikes a primer of the ammunition 5 and ignites it. FIG. 3 shows the breech 1 forward, locked, directly before the firing of a shot.

(18) In FIG. 4, the firing pin 13 has been fired without a cartridge. The firing pin 13 lies with abutting surface 13.6 against an abutting surface 1.2 in the breech (breech bolt). By way of the firing pin safety device 12, the firing pin 13 is returned to its rear position during the return of the control slide 2. The control slide 2 guides the pin 11 downward, and consequently the locking latch 4 out of the breech 1 (see FIG. 5). The second firing pin safety device 18 is engaged again. The first safety device 12, lying against the firing pin 13, is carried along into the rear position. The catching pawl 10 is pressed downward by the nose 13.1 of the firing pin 13 during the return of the breech 1. At this time, the trigger 9 is no longer engaged from below by the ramp 19. By way of the spring 9.2, the downwardly moved-away catching pawl 10 presses the trigger 9 in its engagement, in which it engages by way of its catching edge 9.1 under the catching edge 10.1. The firing pin spring 13.2 is then completely relaxed during the return of the control slide 2, the cocking rocker 14 being removed from the cocking pushrod 15.

(19) In its rear, deactivated position, a new ammunition 5 is delivered to the breech 1. The next shot can take place.

(20) In a preferred embodiment, the control slide 2 and the cocking slide 17 are however configured as one part. The control cams 2.1, 2.3 and also the cocking cam 16 are integrated in a common slide and functionally complement one another.

(21) It goes without saying that the tensioning of the firing pin spring 13.2 by way of the cocking slide 17 can also take place independently of the control slide 2. What is important is the functional coupling of the locking and opening of the breech with the tensioning of the firing pin spring.

(22) The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
