Abstract

FIELD: hand firearm. SUBSTANCE: to enhance safety of use, in the pistol, having a slide, frame, firing mechanism with a spring-loaded trigger, trigger barm spring-loaded sear and hammer with the mainspring, as well as a device for a safety release of the hammer, the safety lock has a lug and is installed in the slide. The hammer is made with a shoulder on the back side of the full cock. The sear is made with a V-shaped fork in the upper part and with a lug in the middle part having an upper pad and a lower bevel. The sear is installed in the frame for engagement of each blade of the V-shaped fork with the safety lug, of the lug upper pad-with the cocking nose and safety lug of the hammer, and of the lug lower bevel - with the shoulder on the back side of the full cock. For a safe release of the hammer the safety lock is turned (putting its thumb catch in the extreme upper position) so that the safety lug acting on the front blade of the V-shaped fork would turn the sear and disengage the lug from the cocking nose. The strike of the firing pin by the hammer is not transmitted to the primer cap since the firing pin is interlocked by the safety lock. EFFECT: enhanced safety. 9 dwg

Description

 The invention relates to weapons technology and can be used in samples of small arms.

 Famous Makarov’s pistol [1] in which a fuse is installed in the bolt, allowing single-shot firing, and the trigger mechanism consists of a trigger, a whisper, a trigger rod with a cocking lever, a trigger. When putting the gun on the fuse, the trigger is automatically safe released. Fuse setting without releasing the trigger is not provided.

 Also known is the Zig-Sauer P6 (P225) pistol [2] in which there is an automatically locking drummer, a trigger trigger, a double-action trigger. Since the gun can only fire when the trigger is pulled, a manual fuse is not installed on it and the gun is ready to fire almost instantly. However, in this gun for the implementation of safe trigger release a special part is installed - the lever for safe trigger release, the button of which is located on the outer surface of the gun. In case of involuntary pressing of this button, the trigger will be intercepted and the shot will not occur. In addition, the lack of a manual fuse when cocked can lead to an accidental pull of the trigger to fire. The objective of the invention is the creation of a gun with increased safety.

 The present invention solves the problem, in which a gun containing a bolt, a frame, a trigger mechanism, consisting of a sear and a trigger, as well as a safe trigger mechanism, differs in that in it the whisper in the upper part has the shape of a V-shaped plug, each feather of which is made in contact with the tooth of a fuse installed on the bolt, and in the middle part has a protrusion, the upper platform of which is made interacting with the safety or combat cock of the trigger, and the lower bevel is made by interaction with a pad made on the trigger.

 The invention is illustrated by drawings.

 In FIG. 1 shows the pistol in the "Fire" fuse position, the trigger is not pulled, the trigger is "off-hook", and the whisper has sunk at the trigger cocking cock; in FIG. 2 pistol in the “Fire” fuse position, the cock is cocked, the trigger is whispering to the cocking cock, the trigger is not pulled; in FIG. 3 gun in the “Fire” fuse position, the trigger is pulled, the sear is out of engagement with the cocking cock and the trigger can go forward; in FIG. 4 pistol in the position after the shot, the trigger is pulled, the trigger is pulled down, the trigger is pulled shutter down, the moment of uncoupling of the protrusion “a” is whispered with the trigger rod, the whisper can fall behind the cocking cock; in FIG. 5 gun in the fuse position "Fuse", the trigger on the "rebound", whispering a fuse for the safety cocking of the trigger, the protrusion of the fuse blocks the rear feather whispered "and"; in FIG. 6 - the gun in the fuse position "Fuse", the cock on the cocking cock, the protrusion of the fuse blocks the rear feather of the sear; in FIG. 7 the gun is in the fuse position "Fuse", the trigger with its platform "e" rests on the lower bevel "g" of the protrusion of the whisper "b", in this position the trigger is locked from the possibility of cocking it; in FIG. 8 gun in position for safe trigger release (the moment of release of the trigger with a protrusion of a whisper); in FIG. 9 - section aa.

 The gun consists of a bolt 1 with a fastener 2 mounted on it and a fuse 3, a frame 4, a trigger 5 with a trigger rod 6, whispered 7 with protrusions "a" and "b", a trigger 8 with a military platoon "c", combat spring 9 On the frame 4 there is a radius groove "g", which includes the cylindrical surface of the fuse 3 (Fig. 5). Thus, the shutter is blocked from moving backward. On the fuse 3, the surface "d" is made (Fig. 6), interacting with the striker 2. Thus, the striker is blocked from moving forward.

 To fire a shot with the cocked trigger, you must press the trigger 5. In this case, the trigger rod 6 is shifted forward and, pressing on the lateral protrusion "a" whispered 7, disengages the upper platform of the protrusion "b" from the cocking "in" trigger 8. Trigger 8 under the action of the mainspring 9 strikes the striker 2, which breaks the capsule, a shot occurs. As a result of the pressure of the powder gases, the bullet is pushed out of the barrel, and the shutter 1 acquires a certain speed, backward. At the beginning of the shutter 1 stroke, the trigger rod 6 is lowered and uncoupled with the sear 7, which, with the further movement of the shutter 1 and the turn of the trigger 8, falls into the cocking cock "in". Then you need to release the trigger 5. The trigger rod 6 moves back and jumps over the ledge of the sear “a”. To produce the next shot, you must again press the trigger.

 If shooting is carried out without first cocking the trigger, then when you press the trigger 5, the trigger 8 is cocked by self-cocking. In this case, the trigger rod 6 moves forward and with its hook "k" presses on the ledge of the trigger "l". Trigger 8 cocked, but does not become a combat platoon "in", because Whisper 7 retracted trigger pull 6 forward. After a certain angle of rotation, the trigger 8 breaks off the hook "to" the trigger rod 6 and strikes the striker. A shot is taking place.

 In the case when the gun is loaded, but it is not necessary to fire a shot, then holding the trigger 8 from the cocking "in", fuse 3 should be turned on by turning the flag to the front position. At the same time, its cylindrical part enters the cutout of the frame and extends beyond the protrusion of the striker "d". At the same time, the fuse tooth blocks the rear feather of the fork of the whispered 7, the upper platform “z” of the whispered cannot exit the cocking cock of the “c”. In this case, the trigger 8 cannot be pulled. If the trigger has been released, then it cannot be cocked, because 7 whispered its protrusion prevents its rotation.

If it is necessary to carry out the safe descent of the trigger 8 from the combat platoon, then after setting the fuse 3 you need to make an additional turn of the fuse up to failure (about 30 ^o ). In this case, the fuse tooth abuts against the front feather of the fork “m” whispered 7 and turns it forward, removing the protrusion from under the cocking cock. At the same time, fuse 3 with its shoulder will additionally block the striker from the possibility of its advancement. Thus, the trigger will be pulled to a blocked firing pin and the shot will not happen. After that, turn the fuse to the "Fuse" position.

 Thus, in the proposed gun, the execution of the upper part of the whisper in the form of a V-shaped fork and the protrusion in the middle part of the sear allows the trigger to be pulled safely from the cock, and the charged pistol to be fused with the cock cocked and lowered, which increases the safety of its operation.

 An experimental batch of pistols was manufactured at TsKIB SOO, tests were conducted with positive results, and design documentation was prepared.
