Description

Invention Shooting knife in sheath - Knife HC relates to survival knives in extreme conditions and combined weapons, namely, the execution of cold steel and barreled weapons in one object

There are various schemes of devices combined weapons. For example: an NRS-2 knife-pistol with a firing mechanism built into the handle, a shot comes from the end of the handle, a short barrel is taken out for loading: the “Chameleon” knife-pistol also has a firing mechanism and four barrels in its handle, firing is carried out along blade, part of the handle - the unit with the trunks leans back to recharge. Known for the shooting knife “OTs-54” “Kit” a short barrel is located in the handle and is directed along the butt of the blade. Knife-revolver is known, the barrel is made along the upper edge of the blade in one part with it, it cannot be long because it will affect the quality of the tip, and the barrel is deformed when the knife is active.

The objective of the invention is to apply a longer barrel to the Knife-NS object and make the work of reloading the cartridge and shot faster and more convenient in the hands, as well as expand the functions of the device’s purpose in survival conditions. The task is achieved in that the knife and scabbard represent a single object for firing, while the removable barrel is located in the scabbard cavity along their entire length, along the blade and interacts with it with fighting stops and coupling devices for fixing, with the possibility of continuing the muzzle part beyond the scabbard. The sheath body, made of a metal plate, as the bearing body of the barrel and the liner for direct sliding of the blade. The plate, bending around the barrel over the butt of the blade, creates a hemisphere for the barrel, is pulled together with the liner flowing around the blade, along their flange edge, with nuts.

The barrel, which has a thickening in the chamber part, is inserted into the hemisphere of the sheath, another thickening above the chamber by half the circumference of the barrel with transverse and longitudinal stops, engages with the recess of the sheath located in the hemisphere end face, the engaged lock already serves as an emphasis in the recoil of the cartridge. The other end of the barrel is clamped by an eccentric lever, using a liner around the barrel, so that the barrel does not touch the sheath in the middle part. The gap between the sheath body and the barrel protects the barrel from deformation during accidental loads on the sheath. The eccentric lever, enveloping the edge of the blade, is mounted on an axis behind the edges of the sheath body and fits between them. Under the lever, at the end of the edges of the sheath, there is a recess under the finger for gripping. A lock, an eccentric lever, as well as a gap between the blade and the barrel make it possible to quickly remove or change the barrel, as well as insert it into constipation, for example; a circular saw or other piercing-cutting objects, in conditions of survival.

The blade of the knife seems solid, from the blade to the back of the handle, with the continuation in the form of a threaded rod for tightening the head. The plane of the blade is narrowed from the butt to the edge of the descent. Dales on both sides extend slightly below the point level closer to the handle and have hole-stops under the balls at the edges. At the beginning of the blade there is a rounded sill, the full thickness of the canvas, followed by a recess under the retainer. The butt is straight, it has hollows -ups-emphasis at the base of the blade. In the handle, the canvas has an increasing emphasis under the guard, then a narrowed strip passes through the middle of the handle. The barrel with a chamber located in the scabbard along the blade, makes it possible to carry out the handle with the trigger mechanism at an angle to the blade, which improves its work in the hands, increases the accuracy of hit when firing.

For rigid fixation of the scabbard with the blade, an eccentric lock with a springy die is used - a clamp located in the scabbard at the base of the handle, opposite the heel of the blade. A die in the form of a bar, with holes in it on one side, and a springy part with a rounded protrusion at the end on the other, is bolted between the edges of the sheath body with a protrusion to the entrance of the blade. Constipation in the form of an elongated oval with a displaced hole, is mounted on an axis below the die, also between the edges of the housing. The geometry of the constipation, which presses the blade against the barrel, is such that the longitudinal stress during the shot to constipation is removed due to the radius of action between the constipation point and the barrel shutter point in the breech part, is transferred to the voltage on the barrel lying on the butt of the blade. Eccentric constipation can be used without a die in direct contact with the blade, the main load falls on the guard with an emphasis in the canvas.

Also, to lock the blade in the sheath and to fix it when sliding in a stable longitudinal direction, balls located on the walls of the sheath are spring-loaded from the outside, at the level of the dolly, which pairwise abut against each other. Springs in the form of plates are attracted to the screed. When the blade enters the sheath, the first pair of balls slides below the edge of the blade, squeezing it to the trunk, fail and slide along the groove of the dol, engage with the stops of the dol or holes for balls located closer to the handle. Moreover, the closer the dol to the handle, respectively, and the balls, the more stable the fixation from vibrations under loads. The second pair of balls also duplicates the fixation in the stops of the beginning of the dol. Ball fixation, can work both in hard mode, using eccentric constipation and combat constipation in the barrel, and in mild stall mode, without constipation, using a spring die, the latter method makes it possible to pull off the sheath when the cartridge is released, and pull out the sleeve after the shot with the ejector . By the force of the springs on the balls by adding them to the main spring, it is possible to control the smoothness of the exit of the balls from the holes of the dol, respectively, and the delay in unlocking the barrel shutter when firing. You can also hold spring-loaded balls with your thumb and forefinger. The trigger mechanism with a longitudinally sliding striker is located in the handle above the canvas, with the striker coming into the plane of the guard with windows for the striker and the ejector, below the window for the blade and screw. The flat guard is surrounded by a flange under the thrust part of the handle, with a hook inside behind the upper thrust part and a canopy over the protruding ejector.

A handle with a flat guard and a blade perform the function of a longitudinally sliding shutter to lock the breech of the barrel. A longitudinal action drummer in the form of one part consists of a striker, a flat bar with descent stops, a round part with an emphasis on the washer and mainspring, and a thread for gripping. The firing pin can be flat with a beveled striking part, so when it is rotated 180 °, it is possible to change the battle on the capsule with the central battle to the battle on the rim - cartridge 5.6. Using a conventional striker with a one-point battle, the barrel stops under cartridge 5.6 are performed taking into account the battle along the edge of the sleeve. The capture of the striker platoon, with a return spring, is twisted to the striker in the cavity of the handle head with emphasis on the mainspring, below the coupling thrust sleeve with a ring, draws the head to the rear of the case by the pin in the blade blade, the ring is placed under the capture as a fuse. Fixation and descent of the cocked striker is carried out due to the plate with a spring-loaded key. A die with a cut under the striker bar is perpendicular to it. The trigger button with a fuse in the form of a latch is located on the side of the handle above the recess under the index finger or in the recess itself, depending on the location of the die. To remove the drummer and change the position of the battle, you need to unscrew the screw using the ring, remove the drummer assembly with the head, turn it and insert it back, while pressing the key so that the stops do not engage. A key with a die can easily exit its cavity. If necessary, the shock trigger device is easily disassembled, or the position of the battle on the capsule with the central battle changes to the battle in the rim of the capsule.

The direction of movement is not the complete removal of the knife from the sheath, coincides with the work of reloading the cartridge, while one hand holds the handle of the Knife-NS, for firing, presses the trigger button with the index finger, and with the other hand you can hold the sheath as a fore-end when firing, relieve constipation, move the sheath with the barrel to reload, pull the hammer from the back of the handle.

The technical result of the invention is: the use of the knife sheath to the shooting knife device functionally, namely, placing the barrel in it, increasing the lethal force and the range of the bullet, due to the possibility of increasing the length of the barrel and caliber, improving the accuracy of hitting the target, due to the length of the barrel and convenient grip on the handle slanted at an angle to the barrel and grip on the sheath as the forend, reducing the time for charging the cartridge by removing the cartridge with the ejector when pulling the knife from the sheath, as well as the ability to quickly change the barrel is of the desired length and caliber with a central battle along the capsule and side, due to the lock system with stops and an eccentric clamp and due to the ability of the striker to change the position of the battle, as well as the possibility of using additional sawing, piercing objects, enhanced knife strength for its intended purpose when installed in handle shock trigger mechanism due to the location of the blade along the entire length of the handle.

The sheath body is made of a metal plate 1, which is bent into a hemisphere under the barrel 3 and is pulled together by flanges with the holes of the liner 2 around the blade 21 with nuts 13. The bend of the plate 1 can be either a semicircular simple shape or a more complicated round shape, with the opposite to the circle linear bends under the blade. The folds are indicated by dashed lines in FIG. 1. The liner 2 may be made of metal or durable plastic. In the cavity of the housing 1-2 there is a window 18 for balls 19 which are pressed by springs 20 with bolts and nuts 13. The barrel 3 is inserted into the rounded cavity of the housing 1, mating with it with a thickening 7, engages with a semicircular vertical stop 4 and horizontal stops 5 in the corresponding the emphasis of the recess 6 in the housing 1. At the end of the sheath, the barrel, through the insert 11, is locked by an eccentric lever 12, with the possibility of rotation on the axis in the form of a bolt with a nut 13, drawn to the walls of the housing 1, so that a gap 17 is created between the barrel 3 and the housing 1. Trunk 3 may be elongated outside the housing 1, in the breech part there is a recess 9 under the ejector 27, a groove 10 under the edges of the sleeve. Detachable front sight 44. The plane of the blade 21 taper from the butt to the edge of the descent. Dales 22 on both sides extend slightly below the point of the tip closer to the handle and have holes on the edges of the holes for balls 19. At the beginning of the blade there is a rounded nut 23, full thickness of the blade 21, followed by a recess under the latch 16. The straight butt, at the base of the blade it has hollows stop-stops 24 for the combat stops of the barrel 8. Spring plate-Lock 16 in the form of a bar with holes on one side and a rounded ledge under the recess of the nut 23 is mounted on bolts with nuts 13 to the housing 1. Below under the ledge of the plate 16 is mounted an eccentric lock 15 also on the axis 13 to the housing 1. and FIG. 1 shows eccentric constipation without the use of a die 16.

The blade 21 of the knife appears to be solid, from the blade to the back of the handle 40, continued in the form of a stud with a thread 43, has a stop 25 under the guard 26 which is mounted on the blade 21 from the tip, has a window for the ejector 27 and a window for the firing pin 29, a canopy of protection the flange 41, and mates with the stop 25, pressing the ejector 27, is screwed to the lower stop of the handle with a screw 42.

Description of the operation of the Knife-NS functionally

The knife in the sheath with the barrel for the shot when the position is locked: the blade 21 in the body 1-2 is suppressed by a lock 15 with a latch 16 with a butt to the barrel, the combat emphasis 8 engages with the emphasis or stops 24 in the butt of the blade 21.

A pair of balls 19 in the walls of the body 1-2 pressed by a spring 20 abuts against the edge in the edge of the valley from the side of the tip, another pair of balls 19 abuts in the recesses - nests in the edge of the valley closer to the handle of the blade. With one hand you can hold the scabbard as the forearm with the other grips the handle. To fire a shot, a free hand pulls the firing pin 28 by the grip 35, the ring 38 pressed under the grip 35 falls to the bottom, the stop of the trigger bar 31 in a rectangular window under the firing bar 28 under the action of the spring enters the recess of the stop 30, to lock the firing pin in the cocked state, the fuse 39 retracts under the key of the strap 31. To fire the key, the key is removed from the fuse, when you press the key, the stop 30 breaks from the stop in the window of the strap 31, under the action of the spring 33, the hammer 32 hits the capsule 25 with a striker 25, the spring 34 pulls the shock IR from the capsule. To adjust the gap between the striker and the capsule, the gripper 35 is tightened. The ring 38 is placed under the gripper 35 as a safety device in the uncharged position. In order to remove the drummer 28 from the handle, you need to unscrew the thrust sleeve 37 from the pin 43 and pull out the head 36 along with the drummer. To reload the cartridge, it is necessary to pull the constipation 15 forward with your free hand, holding the scabbard to pull the handle towards you slightly squeezing it down, the combat constipation 8 disengages, the rounded spring stop 16 passes through the nut 23, while the ejector 27 pulls the sleeve out of the chamber, a pair of balls 19 located closer to the tip, they come out of the stops of the dol, another pair closer to the handle, resting on the upper edge of the dol, disengage from the stops of the holes, slide the hem to the stop at the point and fix the half-open position of the blade in the sheath A cartridge reloading. In order to remove the barrel from the sheath, using the recess 14, you need to grab the lever 12 and pull it out of the walls of the body, the barrel 3 with a relaxed end is removed from the cavity of the body 1-2. The removable front sight 44 with the ball spring-loaded in it, is put on the barrel with the possibility of its fixation in the holes and the groove between them in the barrel, lowered to the bottom when worn, and to the top when fighting.
