Description

The invention relates to non-shotgun mechanical small arms and can be used by the arms industry for the production of small and medium-sized mechanical small arms intended for training sports shooting skills of people in secondary and higher educational institutions, sports and hunting schools, organizations and enterprises, as well as individual use.

Known barrelless non-pistol spring-rope small arms - Crossbow, containing a bed with the neck of a pistol-shaped bed with a handle, which is the main base link, on the neck of which is made a longitudinal gutter-shaped groove designed to move ball-shaped shells - bullets, a flat arcuate spring, fixed in the middle on the end of the bed, the cable, transversely fastened to the ends of the spring, holding them in a compressed state, a lever mechanism, a cocking mechanism with a locking device, a trigger, a kinema directly connected with the lever mechanism, a front sight and an aiming bar installed at the ends of the bed.

The disadvantages of barrelless spring-wire small arms are their large bulkiness and dimensionality, the limited ability to use a crossbow in various positions and non-magnetic bullets of different sizes and shapes, and the quick wear of the cable at the levers.

The closest technical solution to the invention is a barrel spring-piston pneumatic small arms containing a barrel with a front sight at one end and a clutch with a bolt locking device at the second end, a receiver box with a fork at the end, articulated with a sleeve, a coil spring, a piston with a cuff at the end and a back plate located inside the box, and on top - an aiming plate, a bed with a neck of a pistol-type box with a handle fastened with screws with a box, the cocking lever mechanism with a lock kinematically connected with the piston and with the trigger of the trigger located below the bed, which is externally covered by a safety bracket.

The disadvantages of pneumatic small arms with a spring-piston rifle mechanism are the limited ability to use bullets of different calibres of options, the limited small stroke of the piston, the rapid wear of the piston group, the small lethal force due to the low air pressure.

The aim of the present invention is to provide an improved design of a new version of the small arms with spring-inertial mechanism of pushing a bullet in the barrel.

This goal is achieved by the fact that in the barrel spring-piston pneumatic small arms - a pistol containing a barrel with a front sight at one end and a sleeve with a bolt locking device at the second end, a receiver box with a fork at the end, articulated with a barrel sleeve, a coil spring , a piston with a cuff at the end and a back plate located inside the box, and on top - an aiming plate, a bed with a neck of a pistol-shaped box with a handle fastened with screws with a box, a cocking lever mechanism with a locking device ohm, kinematically connected with the piston and with the trigger of the trigger located below the bed, externally covered by a safety bracket, according to the invention, the receiver is combined with the barrel in a single shooting mechanism, where instead of the piston a movable inertial load is used, containing a hollow rod serving as a barrel with a longitudinal a groove for the pusher and the chamber, end heads fixed at the ends of the stem-barrel, an aiming bar and front sight mounted on the heads, a spring pressing for bullets at the chamber, and one-piece load with a pusher inside, mounted on the stem rod, a damping-damping spring with a washer, a bolt with a handle, mounted on an inertial load, a bed with a neck of a pistol-shaped bed with a handle fastened with screws with barrel end heads, locking and trigger levers with a trigger hook, kinematically connected with each other and with an inertial load, a safety bracket, a drum with a flat-coil spring kinematically connected by cables with an inertial load through intermediate pulleys mounted on axis on both sides of the front end head of the barrel.

Figure 1 shows the design diagram of a mechanical barrel spring-inertial small arms - pistols, a copied prototype of approximately m - 1: 1,5.

Device. Mechanical barrel spring-inertial small arms - the pistol consists of a bed with the neck of a pistol-shaped bed with a hollow handle 10, pivotally connected to the barrel case 16, which is combined with the barrel 1 in a single shooting mechanism, where instead of a piston with a pusher 7 a movable inertial load is used 6, located movably on the barrel 1, serving simultaneously as a hollow rod 1, at the ends of which end heads are firmly fixed: front 3 with front sight 2 and rear 4 with aiming plate 5 and butt plate 8. Barrel 1 through end the shafts 3 and 4 are pivotally fastened to the box body by 16 screws 17. In addition, the barrel 1 has a longitudinal groove for the pusher 7 and the cartridge chamber window P, through which bullets 23 are inserted during charging and are held in the barrel 1 by the pressure spring 22 dropping out of it. Mobile inertial the load 6 is equipped with a cocking slide 24 fixed to the pins 25, which, after the inertial load 6 has been put into the fighting position, is removed, in addition, a damping-damping spring 19 with a washer 28 is used for damping at the front end sharp blow inertial load 6 during firing of the front head 3 and giving a pool 23, the pusher 7 extra large inertial force and speed of the bullet 23 upon departure from the barrel 1.

The inertial load 6 is movably on top of the stem barrel 1, and the pusher 7, tightly fastened to the load 6, is located inside the cavity of the barrel 1, they are designed to push the bullet 23 in the barrel 1 when firing at high speed and force due to the large acceleration path the inertial force developed at the end of the barrel 1 by a combat flat-coil spring 15 fixed to the bottom of the receiver 16 in the drum 14 kinematically connected by cables 9 with pins 21 of the inertial load 6 through intermediate pulleys 18 fixed on the axis on both sides of the front end head 3 of the stem shaft 1, and on the bottom of the receiver 16 is a spring-loaded locking mechanism 27 mounted 11, kinematically connected with the trigger 12 of the trigger, externally covered by a clip 13, a hollow handle 10 with springs 17 inside the cavity serves to place in her reserve bullets 23 - store.

Work. Such a design of the barrel spring-inertial small arms - pistols / or rifles / with the receiver 16, combined in a single shooting mechanism with the barrel 1, on which is mounted on top of the moving inertial load 6 instead of the piston, is to prepare for firing.

The first duty is to check the adjustments: front sight 2, aiming strip 5, the tension of the flat-coil spring 15 on the box 14 and, if necessary, adjust by turning the axis of the spring 15 due to the ratchet device of the drum 14. After making sure the strength and reliability of the fastening and setting of all mechanisms, you can proceed to charge the pistol for shooting. A person takes the pistol grip 10 with his right hand, puts on the pins 25 of the inertial load 6 located in front of the barrel 1, the shutter device 24 and with the lever pulls the inertial load 6 onto itself until the locking lever mechanism 11 is actuated, thus the inertial load 6 is introduced into the combat position. Then the person holding the pistol in his right hand takes the bullet 23 with his left hand and inserts it into the barrel 1 under the hold-down spring 22 through the chamber chamber P. The bullet 23 pressed in the barrel 1 with the hold-down spring 22 is firmly and reliably prevented from falling out of the barrel 1.

Thus, the spring-inertial pistol is ready to fire. It remains only to take the target through the sighting mechanism, pull the trigger 12 and the target is hit.

After the shot, operations for loading the barrel with bullets are carried out similarly to the first operation. Bullets 23 can be used in different sizes and calibers for one barrel 1, both round, and elongated or generally long arrow-shaped, inserted into the barrel from the front end, and arrow-shaped bullets can be with cold or hot explosive filling, like a mini-pocket grenade launcher. This is another of his positive virtues.
