The upper surface of the protrusion 97 is made in the form of a radius. On the back wall of the bar 96 with the bottom edge there is a locking protrusion 100, designed to fix the universal trigger mechanism 36 or 41 when installing weapons in the trigger housing 22, which facilitates the assembly of weapons.
(82) FIG. 28 shows a bottom view of the sear 11 for cocking pieces with a safety. For trigger mechanisms with a safety in the sear 11 on the support platform 98, it sear, a T-shaped protrusion 101 with an inclined platform 102 is made. The inclined platform 102 forms an acute angle d102 with a sear support platform 98 equal to 35-45 degrees, which is the optimal value for creating safety efforts.
(83) FIG. 29 shows a side view of the single-shot sear 27. The single-shot sear 27, contains a square rod 103. On the back of the square rod 103 a T-shaped protrusion is made, consisting of a section 104 of the sear and the rack 105 of the sear. Inside the square rod 103 there is a blind hole 106 for the spring of the trigger mechanism 30.
(84) FIG. 30 shows a cross-section along A-A of the single-shot sear 27 (see FIG. 29). This configuration is made in the form of portion of a square rod 103 and section 104 sears having a lower horizontal surface 107, front vertical surface 108 and a rear radius surface 109.
(85) FIG. 31 shows a side view of the multifunctional switch 28. The multifunctional switch 28 contains a trapezoidal bar 110, the front end of the indicated trapezoidal bar 110 is made in the form of a rack 111 with a horizontal protrusion 112. In the rear of the trapezoidal bar 110 a T-shaped protrusion is made, consisting of the sear section 113 and the sear rack 105. Inside the trapezoid bar 110, a blind hole 106 was made for the spring of the trigger mechanism 30 and the axis of the multifunctional switch 29. On the rear bottom surface of the trapezoidal bar 110 a protrusion is made, 114, acting as a fire lever.
(86) FIG. 32 shows a cross-section A-A through the sear section 113 (see FIG. 31) for the multifunctional switch 28. This configuration is made as portion of the trapezoid bar 110 and the sear section 113 having the lower inclined surface 115, the front vertical surface 108 and a back radius surface 109.
(87) FIG. 33 shows a side view of the axis 29 of the multifunctional switch 28. The axis of the multifunctional switch 29 is made with a conical section 116 with a spherical head 117, which passes into cylindrical portion 118, which passes into cylindrical portion 119 with a smaller diameter, which ends with a chamfer 120.
(88) The operation of the latch 7 of the magazine 1 in a fixed position is shown in FIG. 34, FIG. 35 (section 1-1 in FIG. 34), FIG. 36 (section 2-2 in FIG. 34). When the magazine 1 is inserted into the corresponding cavity of the trigger housing 22, the safety latch spring 5 presses on the pusher 6 of the latch 7 of the magazine 1, which pushes the protrusion 83 of the latch 7 of the magazine 1 with its axis 77. In addition, the latch 7 of the magazine 1 rotates and engages with its locking protrusion 82 meshing with the locking protrusion 2 of the magazine 1. The latch 7 of the magazine 1 is fixed by the trigger bracket 121 of the trigger housing 22, thereby effectively fixing the magazine 1 inside the weapon. In this case, a gap B4 is formed between the upper end of the cylindrical portion 75 of the pusher of the magazine latch 6 and the lower surface of the cylindrical section 72 of the safety latch 4.
(89) When the safety catch 3 is pressed, the spherical head 71 of the safety latch 4 is in the spherical recess 70 in the compressed state using the spring 5 of the safety latch 4. In this case, the trigger bar 23 or 24 or 25 or 26 prevents the safety catch 3 from falling out of the trigger housing 22. The safety protrusion 85 of the trigger bar 23 or 24 or 25 or 26 has the possibility to move in the large slot 65 of the safety catch 3. This makes it possible to fire a shot when the cocking piece 84 of the trigger bar 23 or 24 or 25 or 26 is pressed.
(90) FIG. 37, FIG. 38 (Section 1-1 in FIG. 37), FIG. 39 (Section 2-2 in FIG. 37), show the operation of the latch 7 of the magazine 1 when pressed. When the magazine 1 is removed or inserted into the corresponding cavity of the trigger housing 22, then the latch 7 of the magazine 1 is fully pressed, the protrusion 83 presses the pusher 6, which compresses the safety latch spring 5. At this time, the locking protrusion 82 on the latch 7 comes out from engagement with the locking protrusion 2 of the magazine 1 and the magazine 1 can be removed from the corresponding cavity of the trigger housing 22. The latch 7 of the magazine 1 is designed for both the right and left hands of the user. Since the latch 7 of the magazine 1 is in a spring-loaded state, the safety latch spring 5, and does not protrude from the trigger housing 22, it is protected from accidental emissions. The protrusion 83 of the latch 7 of the magazine 1 is rotated by a certain angle due to the fact that the upper end of the cylindrical portion 75 of the magazine pusher 6 abuts against the lower surface of the cylindrical section 72 of the latch 4 of the safety catch 3, which does not allow the latch 7 of the magazine 1 to spontaneously. At the same time, there is no gap B4 between the upper end of the cylindrical portion 72 of the magazine pusher 6 and the lower surface of the cylindrical section 69 of the safety latch 4.
(91) When the safety catch 3 is triggered, the spherical head 71 of the safety latch 4 is located in the spherical recess 70 and, under the action of the safety latch 4 spring 5, lifts the end of the safety catch 3. Due to the through slot of the triangular shape 67 of the safety catch 3, a protrusion 69 is formed at the end of the safety catch 3, which abuts against the trigger housing 22 and does not allow direct pressure on the safety catch 3 to remove from the safety position. In this case, the trigger bar 23 or 24 or 25 or 26 does not allow the safety catch 3 to fall out of the trigger housing 22. Moreover, the safety protrusion 85 of the trigger bar 23 or 24 or 25 or 26 does not have the possibility to move in the small slot 66 of the safety catch 3. This does not allow you to press on the trigger bar 23 or 24 or 25 or 26 and fire. To remove safety catch 3 from the safety position, safety catch 3 must be lowered down and pressed down. When the trigger bar 23 or 24 or 25 or 26 is removed, the safety catch 3 is disassembled by pushing it from the landing hole of the trigger housing 22 in any direction.
(92) FIGS. 40 and 41 show the disassembly and assembly of the magazine latch 7. When the receiver 20 is removed from the trigger housing 22 and the safety catch 3 is removed, the safety latch 4, the pusher spring 5 with the magazine pusher 6 are removed one bar from the blind hole 122 of the trigger housing 22. Then the latch 7 of the magazine 1 is pressed down until it stops. In this case, the locking protrusion of the magazine 82 and the protrusion of the magazine 83 on the latch 7 of the magazine are installed opposite the through hole 123 in the corresponding cavity of the trigger housing 22, and the latch 7 of the magazine 1 is removed. In the proposed invention, the latch 7 of the magazine 1 is disassembled without special tools. To assemble the latch 7 of the magazine 1, the disassembling steps are reversed.
(93) FIGS. 42 and 43 show the cocking indication of the cocking piece 17. When the cocking 17 is cocked, the cocking indicator 52 of the cocking piece 17 passes through its notched section 53 through the slot 124 with the opening of the trigger housing 22. The notched section 53 allows to determine the cocking piece 17 cocked position visually and to the touch. When the cocking piece 17 is lowered, a smooth section 54 of the cocking indicator 52 appears in the slot with the hole 124 of the trigger housing 22. The smooth section 54 of the cocking indicator 52 allows to determine the lowered position of the cocking piece 17 visually and by touch.
(94) FIG. 44 shows a side view of a fragment of a longitudinal section of the mechanism of the adjusting screw 13. Adjusting the compression force of the cocking piece of the spring 12 of the trigger bar: by adjusting the screw 13 in the threaded stop 125 of the receiver 20, it is possible to adjust the compression force of the spring of the trigger bar 12. After setting the required compression force of the spring of the trigger bar 12, the adjusting screw 13 must be locked with the lock nut 14 of the adjusting screw, thereby preventing the force of the spring of the trigger bar 12 from changing during operation.
(95) FIG. 45, FIG. 46 and FIG. 47 show the operation of the cocking piece 17 and sear 11 in the safety mode from an arbitrary cocking. When the trigger bar 23 or 24 or 25 or 26 is pressed, sear 11 moves and selects the gap of free thrust of the trigger bar 23 or 24 or 25 or 26 with a trigger. Further, the T-shaped protrusion 101 with the inclined platform 102 on the sear 11 abuts against the protrusion 56 with the inclined platform 57 on the cocking piece 17. In order to pass the sear 11 further, it is necessary to increase the force of pressing the trigger bar 23 or 24 or 25 or 26. This occurs due to the fact that the sear 11, with its T-shaped protrusion 101, needs to overcome the protrusion 56 on the cocking piece 17. The angle d102 of the inclined platform 102 on the sear 11 and the angle d57 of the inclined platform 57 on the cocking piece 17 are made the same, and changing their inclination is possible, adjust the safety force. After overcoming the T-shaped protrusion 101 of the protrusion 56 is the breakdown of the cocking piece 17 and the shot.
(96) FIG. 48 shows the operation of the safety catch 3 in the position of safety against arbitrary cocking. When the safety catch 3 is in the position of safety against arbitrary cocking, the trigger bar 23 or 24 or 25 or 26, and with it sear 11, does not have the possibility to move. The cocking piece 17 is in the cocked position. When trying to cock a weapon, a bulge 33 at the rear end of the lock frame 31 abuts the cocking piece 17 and tries to cock it. In this case, the protrusion 55 on the cocking piece 17 abuts against the protrusion 97, sears 11 and bars the further movement of the lock frame 31, thereby preventing the weapon from cocking.
(97) FIG. 49, FIG. 50, FIG. 51, and FIG. 52 show the operation of the multifunctional switch 28. To switch from an automatic fire mode to a semi-automatic fire mode, the protrusion 114 of the multifunctional switch 28 is pushed fully forward, up and back, with a horizontal protrusion 112 passes into the rectangular hole 94 of the trigger bar 24 or 26. Then, the horizontal protrusion 112 of the multifunctional switch 28 passes forward and down. In addition, the horizontal protrusion 112 will take a lower position in the rectangular cavity 91 of the trigger bar 24 or 26 and the rack 111 of the multifunctional switch 28 will disengage from the hook-shaped protrusion 32 of the lock frame 31. The spring 30 of the trigger mechanism is fully compressed and the axis 29 of the switch 28 is in the lowest position. Then the horizontal protrusion 112 will take a position in the rectangular cavity 91 of the trigger bar 24 or 26. To switch from the semi-automatic fire mode to the automatic fire mode, you need to do all of the above, the above steps in reverse order. Multifunctional switch 28 improves fire efficiency and accuracy because switching fires can be done without looking away from a gun's sight with the right or left hand arrow.
(98) Considering the above, examples of the proposed universal percussion trigger mechanism may be as follows:
(99) FIG. 53, FIG. 54, FIG. 55, and FIG. 56 show the operation of the universal percussion trigger mechanism for semi-automatic fire. When pressing the trigger bar 23 or 25, it presses on the sear 11 and the support platform 98 of the sear slides from the cocking platform 50 of the cocking piece 17. In this position, the spring 12 of the trigger bar 23, 25 and the mainsprings 19 are in maximum load mode. Under the action of the mainsprings 19, the cocking piece 17 is rotated. At the same time, with its percussion platform 46 it strikes the firing pin 8. Then the firing pin 8 compresses the spring 9 of the firing pin 8 and pierces the capsule with an ammunition igniter. A shot is taking place. At such a moment, the lock frame 31 rolls back and a bulge 33 at the rear end of the lock frame 31 cocks the cocking piece 17. The tip 48 of the cocking piece hits the rear radius surface 109 of the single-shot sear 27 and pushes the single-shot sear 27, compressing the spring 30 of the trigger mechanism. The protrusion with the platform 51 of the cocking piece 17 becomes on the lower horizontal surface 107 of the single-shot sear 27 and holds the cocking piece 17, in cocked position with the trigger bar 23 or 25 being pressed. The lock frame 31 reaches the extreme rear position. The returnable spring 34 will acquire maximum compression and begins to expand along the guide rod 35 of the returnable spring 34, while pushing the lock frame 31 forward. Removing the protrusion from the platform 51 of the cocking piece 17 from the lower horizontal surface 107 of the single-shot sear 27, will not happen. To perform the next shot, it is necessary to trigger the trigger bar 23 or 25. In this case, under the action of the pull the spring 12 of the trigger bar 23, 25, the trigger bar 23 or 25 will move forward with the single-shot sear 27 and sear 11. The protrusion with the platform 51 of the cocking piece 17 will disengage from the bottom horizontal surface 107 of the single-shot sear 27. The protrusion with the platform 51 of the cocked position 50 of the cocking piece 17, will go into the sear support platform 98 and will be on the cocked cocking. For firing the next shot, it is required to press and trigger the trigger bar 23 or 25.
(100) FIG. 57, FIG. 58, FIG. 59, and FIG. 60 show the operation of the universal trigger mechanism for semi-automatic and automatic fire in the semi-automatic fire mode. When pressing the trigger bar 24 or 26, it presses on the sear 11 and the sear support platform 98 slides from the cocking platform 50 of the cocking piece 17. In this position, the spring of the trigger bar 12 and the mainsprings 19 are in maximum load mode. Under the action of the mainsprings 19, the cocking piece 17 rotates. At the same time, with its cocking piece platform 46, it strikes the firing pin 8. Then the firing pin 8 compresses the spring 9 of the firing pin and pierces the capsule with an ammunition igniter. A shot is taking place. At such a moment, the lock frame 31 rolls back and the bulge 33 at the rear end of the lock frame 31 rolls the cocking piece 17. The cocking piece tip 48 hits the rear radius surface 109 of the multifunctional switch 28 and pushes the multifunctional switch 28, compressing the spring of the trigger mechanism 30. The protrusion with the platform 51 of the cocking piece 17 becomes on the lower inclined surface 115 of the multifunctional switch 28 and holds the cocking piece 17 in the cocked position with the trigger bar 24 or 26 pressed. The lock frame 31 reaches its extreme rear position. The returnable spring 34 gains maximum compression and begins to expand along the guide rod 35 of the returnable spring 34, pushing the lock frame 31 forward. In this case, the lock frame 31, with its hook-shaped protrusion 32, will pass over the rack 111 of the multifunctional switch 28. Removing the protrusion from the platform 51 of the cocking piece 17 from the lower inclined surface 115 of the multifunctional switch 28 will not occur. To perform the next shot, it is required to release the trigger bar 24 or 26. In this case, under the influence of the spring 12 of the trigger bar, the trigger bar 24 or 26 move forward with the multifunctional switch 28 and sear 11. The protrusion with the platform 51 of the cocking piece 17 is disengaged from the lower inclined surface 115 of the multifunctional switch 28, and the protrusion with the platform of the cocked position 50 of the cocking piece 17, will pass into the sear support platform 98 and will be on the cocked cocking. For firing the next shot, it is required to release and press the trigger bar 24 or 26.
(101) FIG. 61, FIG. 62, FIG. 63, and FIG. 64 shows the operation of the universal percussion trigger mechanism for semi-automatic and automatic fire in automatic fire mode. When pressing the trigger bar 24 or 26, it presses on the sear 11 and the sear support platform 98 slides from the cocking platform 50 of the cocking piece 17. In this position, the traction spring 12 with a trigger and the mainsprings 19 are in maximum load mode. Under impact ofthe mainsprings 19, the cocking piece 17 is rotated, while its percussion platform 46 strikes the firing pin 8. Then the firing pin 8 compresses the spring 9 of the firing pin 8 and pierces the capsule of igniter ammunition. A shot occurs. At such a moment, the lock frame 31 rolls back and a bulge 33, at the rear end of the lock frame 31, cocks the cocking piece 17. The cocking piece tip 48 hits the rear radius surface 109 of the multifunctional switch 28 and pushes the multifunctional switch 28, compressing the spring of the trigger mechanism 30 of the percussion trigger mechanism. The protrusion with the platform 51 of the cocking piece 17, becomes on the lower inclined surface 115 of the multifunctional switch 28 and holds the cocking piece 17 in the cocked position with the trigger bar 24 or 26 being pressed. The lock frame 31 reaches its extreme rear position. The returnable spring 34 gains maximum compression and begins to expand along the guide rod 35 of the returnable spring 34, pushing the lock frame 31 forward. In this case, the lock frame 31, with its hook-shaped protrusion 32, engages with the rack 111 of the multifunctional switch 28. With further forward movement of the lock frame 31, the lower inclined surface 115, of the multifunctional switch 28, disengages from the protrusion with the platform 51 of the cocking piece 17. Mainsprings 19 unclench and turn the cocking piece 17, which strikes the firing pin 8 with its percussion platform 46. The firing pin 8 compresses the firing pin's spring 9 and pierces the capsule of the ammunition igniter. Another shot occurs. If the trigger bar 24 or 25 is in the pressed position, automatic firing will continue until the ammunition runs out in magazine 1.
(102) The proposed design of the percussion trigger mechanism was implemented on test models for weapons with a magazine in the pistol grip, for weapons made according the bullpup scheme and for weapons made with a side handle, and showed the ease of use, the ability to adjust the trigger force and prevent accidental fire.
