Description

 A multi-barrel self-cocking pistol is designed for use in the defense industry and as a weapon of self-defense.

 Known design of a multi-barrel pistol according to US patent N 3346983 C. 42-47. The design of the analogue contains a hinged block of trunks, a locking unit, a housing with a handle, an impact and trigger mechanisms, a fuse. The patent describes the design features of the mechanism for pushing cartridges and sleeves from the channels of the trunks when opening the barrel unit.

 In U.S. Patent No. 4,625,443, dated September 7, 1984, to provide for the successive breaking of capsules of cartridges located in different barrels with one trigger on the trigger in a plane perpendicular to the plane of its rotation, an impact mechanism is installed that pivots to the next hammer when the trigger is cocked. The disadvantages of the design is the high resistance when cocking, which increases the pulling force, and also increases the overall characteristics.

 The prototype of the invention in terms of common design features is described in US patent N 3260009 C. 42-69, which is a four-barreled self-cocking pistol containing a folding barrel block, with a locking unit having a cap bar, a trigger mechanism with a hammer mounted on the longitudinal axis with discrete rotation, sights and a housing with a handle. The drummer is mounted on a guide rod, which simultaneously serves as the guide rod of the mainspring and the axis of rotation of the hammer, and is fixed in the housing. The barrel block is locked by a locking lever with a central hole covering the combat ledge of the hull; the rear sight is installed in the hull. The shock mechanism is made in the form of spring-loaded strikers. On a spring-loaded striker screw grooves are made, communicating with each other in the form of a continuous pattern. Inside the drummer, a compression spring is placed on its axis. Rebound springs are placed on each striker. A pivot lock interacting with the profile grooves of the striker is mounted in the gun body. The trigger sear is mounted in the trigger and interacts with the annular protrusion of the trigger. The trigger is reset due to the radial trajectory of the sear.

The disadvantages of the prototype:
large dimensions of the gun, due to the placement of the rebound spring on the strikers and the spring of the percussion mechanism in the niche of the hammer with an emphasis on the back of the gun;
bulkiness of the structure;
large dimensions of the drummer, due to the need to place a spring in it;
a large pulling force, due to the large dimensions of the hammer and a large resistance when turning the hammer due to the steep angle of the helical spiral, due to the large diameter of the hammer;
To place the sight on the case, an independent protrusion is made, which complicates the manufacturing technology.

 The aim of the invention is to eliminate the disadvantages of the prototype.

The purpose of the invention is achieved by the introduction of the following design features:
the axis of the drummer is fixed in a frame mounted in the longitudinal groove of the housing with the possibility of reciprocating motion under the action of the mainspring, end spring and trigger;
the hammer is rigidly fixed on the drummer;
the mainspring, rebound spring and striker pivot lock are mounted on the rod;
the rod is rigidly fixed in the longitudinal groove of the housing;
the rear part of the body, covering the drummer, is made in the form of a circuit casing and has an opening for free exit of the drummer;
the cap strip of the locking unit is made integral with the barrel unit and has a through hole for the reciprocal protrusion of the housing;
the reciprocal protrusion of the housing is made with a longitudinal groove, which is the entire sight.

 This design of the gun is simple both in manufacture and in assembly, and allows you to minimize the trigger and exclude a number of parts required in the previously described designs. The descent force is reduced by reducing the diametrical dimensions of the striker and its length. In addition, when changing the clip, the barrel unit can be tipped back with one hand holding the gun. The reliability of the gun is improved due to a clearer fixation of the elements of the percussion mechanism.

 The invention is illustrated in the drawing, where in FIG. 1 shows a schematic diagram of a gun, FIG. 2 shows the construction of the frame of the percussion mechanism; FIG. 3 shows the location of the pillar, section AA shows the fixing of the rod in the gun body and the placement of the frame of the percussion mechanism in the gun body, FIG. 4 shows the design of a removable casing.

 A multi-barrel self-cocking gun contains a barrel unit 1, a housing 2, a locking lever 3, a trigger mechanism 4, a striking mechanism consisting of a frame 5, a striker 6, the axis of the striker 7, a rod 8, a combat spring 9, an abutment 10, a release spring 11, an extractor 12 , latch 13, emphasis 14, casing 15, casing spring 16.

 The proposed gun is made with a folding block of trunks.

 The blocking of the barrel block is carried out by a pivoting side lever 3 by contacting its protrusion with the tooth “a” of the barrel block, and also with a cap strip “b”, made integral with the barrel block 1, a through hole “c”, which covers the counter protrusion “d” of the body. The counter protrusion "d" is made with a longitudinal groove "e", which is entirely and located above the flange "b".

 The extraction of the cartridge holder (not shown in the drawing) is provided by moving the spring-loaded extractor 12, which contacts when opening the barrel unit with the protrusion of the housing.

 For contacting the striker "O" with capsule cartridges, through holes are made through the holes corresponding to the location of the trunks.

 The percussion mechanism consists of a frame 5 mounted in a longitudinal groove of the body, rigidly connected to the frame of the longitudinal axis 7, a hammer 6, located on the axis 7 with the possibility of discrete rotation, the hammer "O", rigidly mounted on the hammer, the mainspring 9 and the end spring 11 located on the rod 8, rigidly fixed in the longitudinal groove of the housing by means of an abutment 10 in contact with the frame in its extreme forward position and a spring-loaded latch 13 mounted in the recess of the rod "f" with limited movement in the direction perpendicular to the axis of the hammer and in contact with the longitudinally-screw grooves of the hammer. The frame is provided with the possibility of reciprocating movement along the longitudinal groove of the body under the action of the mainspring, rebound spring and trigger.

 Frame 5 is shown in FIG. 2 is made with a longitudinal niche "g" to accommodate a rod with a combat spring and two jumpers. In one jumper, a longitudinal hole "h" is made to accommodate the axis of the hammer and perpendicular to it a hole "i" to accommodate the locking pin. On the other jumper, a hole “k”, parallel to the niche, is made for accommodating the rod and a through outer groove “l”, the end face “m” of which interacts with the stop 10 installed in the housing. The end face “n” of the frame compresses the end spring 11 when the cartridge capsule is tilted; in the end position, the end spring 11 is in contact with the end face “n” of the frame and the stop 10 to ensure the hammer is drowned relative to the end surface of the housing in contact with the cartridges. The combat platoon “p” was made on the frame for interaction with the sear “r” of the trigger 4. The contact was uncovered by the emphasis 14 of the frame.

 The drummer 6 is made with a central longitudinal hole to accommodate the axis of the drummer 7, on which the drummer rotates freely. The drummer is equipped with longitudinally-screw grooves along which the spring-loaded latch 13 moves, turning the drummer by a certain angle. The latch accurately orientates and detachably holds the hammer in one of its shock positions.

 The rod 8 is rigidly fixed in the longitudinal groove of the housing and is made in the form of a longitudinal axis with a head at the end, in which there is a niche "f" for accommodating the latch 13 and its spring. The latch protrudes relative to the rod 8 for contact with the hammer. A protrusion "s" is made on the rod to fix the rod in a frame in which a groove "t" is made for this protrusion, which provides sufficient travel with a guarantee of breaking the cartridge capsule.

 The rear part of the body, covering the drummer, is made in the form of a removable casing 15, shown in FIG. 4 and fixed to the housing by a spring 16 and longitudinal protrusions covering the housing. The casing has an opening for free exit of the drummer. The casing protects the percussion mechanism from damage and contamination when it is inoperative, in addition, it serves as a safety device when the gun falls in the upright position by the barrels. The latter is due to the fact that the movement of the shock mechanism is limited by the end face of the casing, preventing it from full movement and the operation of the capsule due to insufficient breaking energy.

 To produce a shot, it is necessary to tilt the barrel unit and charge it with cartridges. Then close the barrel block, fixing it with the lever 3. Having selected the target, you must press the trigger. In this case, the “r” whispered behind the cocking “p” cocks the frame 5, compressing the mainspring 9 located on the rod 8. The drummer 6 together with the frame moves, turning from the action of the latch 13. The stop 14 brings the sear out from under the cocking of the frame, and the frame, no longer holding on to anything, under the action of the mainspring moves forward and punches the cartridge’s capsule, squeezing the end spring 11 during the period of tipping the capsule. Then, under the action of the end spring, the striker with the striker moves back to the drowning position of the striker relative to the plane in contact with the torus chuck it.

 To produce the next shot, you must repeat the action.

 When using the present invention, the positive effect is expressed in a decrease in overall weight and weight characteristics, in a decrease in the pulling force due to a decrease in the resistance to rotation of the striker by reducing the diametrical dimensions of the striker and its length, in a reduction in the nomenclature of parts due to the implementation of the rear sight on the gun's gun support and at the same time with a striker, in simplifying the design, in improving the reliability of the pistol, due to a clearer fixation of the elements of the striking mechanism, in improving the ex luatatsionnyh characteristics due to improved overall and weight characteristics, to improve the safety of use by avoiding unauthorized shot when falling into gun barrels up position by forcing stroke limit moving parts.
