(57) Abstract: Usage: in the small arms firing from the shoulder, in particular, weapons, rechargeable movement of the forearm. The invention is: to use a cartridge of small length and reduce the dimensions of the weapon entered a specific ratio of the linear dimensions of the elements of the feed mechanism of a holder and a locking mechanism movable parts and the trigger mechanism. The desired effect is provided by the arrangement of the stop facing the longitudinal bore of the tubular store, from hemp stem at a distance smaller than the length of the shutter, the location of the axis of swing of the feed lever lock cartridge at a distance greater than the length of the chamber of the barrel and the end face of the blocking lever from the hemp stem at a distance smaller than the length of the shutter. 1 Il. The invention relates to small arms and, in particular, to hunting firearms (shotgun, rifle), intended for firing ammunition with fraction and different types of bullets, including special that allows you to use a shotgun for self-defense of citizens from criminal elements. In hunting ground known application of Jania, information disclosed in the magazine "Hunting and hunting", N 11, 1980 Small arms with a movable forearm has a generally tubular, located under the barrel, which ensures the compactness of the whole structure. Weapons with a movable forearm to recharge in combination with underbarrel tubular magazine allows to deliver precision fire single shots with a relatively high firing rate when the manual feeding of cartridges from the magazine into the cartridge chamber of the barrel. Known gun with a movable forearm to recharge "Winchester model 1200" 12-gauge, selected as a prototype. The prototype contains a barrel for U.S. patent N 4035944, cast box with front and rear inserts, located under the barrel tubular magazine (see U.S. patents NN 3165849, 3432956, 3611608), the locking mechanism with a rotating bolt for U.S. patent N 3156993, firing and feeding mechanism for U.S. patent N 3373519 and mechanism of recharge from the rolling of the forearm, and the locking lever. The connection of the trunk with a box made according to U.S. patent N 3163952. The details of the firing mechanism is mounted on a base, on top of its platform. On the basis of the firing mechanism of the hinge in a vertical CLASS="ptx2">In the prototype at the location of the recharge mechanism in its extreme rear position, the locked barrel and cocked the details of the trigger lock lever is engaged with the mechanism of recharge and keeps it from moving back. Lock lever disengages from the recharge mechanism at the time of trigger firing mechanism (when fired or forced the influence of the shot). Due to its structural features, namely, the combination of the length of the chamber, the length of the shutter, the distance from the stump of the barrel (the end of the barrel into the receiver until it stops zaslannogo store cartridge, the distance from the stop of the cartridge to the axis of rotation of the feed lever, it is the length of the bolt is less than the distance from the stump of the barrel until it stops cartridge, zaslannogo of the tubular store, the distance from the focus of the cartridge to the axis of the swing the pickup arm is less than the length of the chamber of the barrel, and the distance from the stump of the barrel before the end of the blocking lever is greater than the length of the shutter. These design features of the prototype is not specified patents, but are an integral essence of the design. The use of named design features in the development of weapons of p the awning, and the compliance of the dimensional ratios in combination with a short cartridge, and therefore with a short chamber, will lead to the bulkiness of the weapon design, great weight and size characteristics, which degrades the performance characteristics of weapons in General. The aim of the invention is the creation of weapons under short cartridge with grabovym charge, and different types of bullets, Cavalcanti in shortened sleeve hunting cartridge, the ballistic characteristics of which are provided with special requirements. While the requirements for the weapons include grenade shop manual reload forearm, the use of a rotary shutter Drive his feeding and firing mechanism, less linear and dimensional and weight characteristics. When designing used the above patents structural assemblies and mechanisms, however, structurally modified linear correlation between the location of the focus of the cartridge relative to the shutter, the location of the axis of rotation of the feed lever from one extreme position to the cartridge, and the distance from the stump of the barrel before the end of the blocking lever, which allowed to reduce the weight and size characteristics of weapons than what allows to use the design features of the analog prototype chambered for the smaller size with reduced weight and size characteristics of weapons by introducing the following distinctive design features:the length of the bolt is larger than the distance from the stump of the barrel until it stops cartridge, fed from an under-barrel store. the distance from the focus of the cartridge to the axis of the swing the pickup arm is greater than the length of the chamber of the barrel; the distance from the stump of the barrel before the end of the blocking lever is less than the length of the shutter. Circuit design of small arms shown in the drawing, which shows the position of the mechanisms of the weapon (carbine) when the hammer from striking the firing pin shutter (process shot). The firearm includes a barrel 1, the receiver box 2, shutter 3, the frame of the shutter 4, the striker 5, the pivot pin 6, the forearm 7, the thrust of the forearm 8, the tubular store 9, the lock barrel 10, the feed lever 11, the locking lever 12, the trigger 13, the axis of swing of the pickup arm 14, the stop 15. The barrel 1 is made removable and is fixed in the receiver hole 16 and end the barrel (not shown) and the guide 17, presses the clamp 10 mounted on the tubular store using the threaded connection of the tubular store 9 in turn is fixed in the receiver 2 by means of the threaded connection. The locking shaft is turning the bolt by calling it martial tabs over the edge of the receiver, turn C the ABC frame 4, hold the bolt in the locked position, the locking lever 12, the end face 18 which abuts against the end face 19 of the thrust of the forearm 8. Working principle of small arms following. Before firing the tube store is filled with cartridges. For the production of shot you need to click on the tab of the locking arm and the forearm to move themselves in the direction of the butt. While the thrust of the forearm, rigidly United with protrusions and grooves with a frame, move the frame to the rearmost position, and the end face 18 of the locking lever pressing protrusion 20 allows to move freely drawn forearm. The pivot pin 6, moving in a curved groove (not shown), opens the shutter at a certain angle and combat displays the projections of the shutter due to fighting the projections of the receiver (not shown). The shutter frame, moving backward, vzvoda the trigger 13 of the trigger and moves the lever 21, pivotally connected to the feed lever 11, swinging on the axis 14. Along with this, pull the forearm when moved to the rear position affects the qualifier rounds in the tubular magazine, and released the cartridge spring store shall be expedited to the stop 15, while the bottom of the cartridge is kept feeding area is estate in the forward position. The lever 21, and temporarily coupled to the frame by means of the protrusion 23 with a corresponding ledge of the frame, retracts, moving at a certain angle to the axis 24 of rotation of the lever about the axis 14 of the feed lever and the platform 22 along with the cartridge moves up to the line of disilane. Next, the bolt pushes the cartridge into the chamber and stragiht feed lever, under the action of the spring returns to its original lower position. When the trigger is pulled, the trigger 13 under the action of the mainspring strikes the striker 5, and that, in turn, pins the cap of the cartridge. Is shot. In small arms provided by the impossibility of pressing the trigger retraction of the locking lever thrust of the forearm. For the production of the next shot, you must repeat the above steps. In small arms, the end face 25 of emphasis is from the hemp stem at a distance that is less than the length B of the shutter, which due to their design exceeds the size And, due to the small length of the cartridge for special purposes. The length of the shutter is determined by the need to accommodate the pin, the pivot pin, the spring of the ejector 26. The swing axis 14 of the feed lever 11 is located at a certain angle swing the pickup arm to ensure reliable zasilania cartridge in the chamber of the barrel. The reduction In size to within less than the length of the chamber of the barrel will result in violation of the brachial ratios leverage the trigger and feeding mechanisms. In addition, the locking lever due to the need to maintain lock the trigger when cocking moving parts in combination with unlocking the trigger mechanism in its extreme rear position of the movable parts and the impossibility of backward motion of moving parts without pressing the stop 20 is designed so that its end 18 is separated from the hemp stem at a distance D that is less than the length of the bolt B. the length of the shutter due to the design of the locking Assembly of the prototype, and the ratio of shoulder arms, the deployment of elements of the descent, feeding the cartridge and locking mechanisms design features appropriate mechanisms prototype. Using the proposed small arms positive effect is to reduce the overall size of the weapon by introducing a specific ratio of the linear dimensions of the elements of the feed mechanism of a holder and a locking mechanism movable parts, and a release mechanism that, in General, improves operational characterologic and feeding mechanisms in the new as in a weapon chambered for a small length from providing reduced overall performance. SMALL ARMS, containing the barrel with the breech bolt, receiver box, under-barrel tubular magazine with a spring, the drummer with the stopper pin which is located in the profile groove of the frame, movable handguard, United by rods to the frame, the trigger mechanism with the trigger lock lever in contact with the thrust of the forearm and the trigger mechanism, the feed lever, swinging on an axis, one arm of which is placed the shaking stops, and on the other the supply area, the focus turned to the longitudinal bore of the tubular store, characterized in that it is the distance from the stop facing the longitudinal hole store, to stump the trunk is less than the length of the shutter, the distance from the focus to the axis of the swing the pickup arm is greater than the length of the chamber of the barrel, and the distance from the end of the blocking lever to stump the trunk is less than the length of the shutter.
