The present invention relates to the field of weapons, namely for small repeating arms pumping type, perezarazhenie which is carried out by movement of the forearm.

Known small repeating arms (1), which contains the butt, arm, case, gun box, movable barrel with a cartridge chamber, nastolnyy store with the mechanism of the cut-off rounds, the applicant cartridges, the extraction mechanism and the trigger mechanism.

This weapon feeder cartridges are made in the form of a spring plate in the form of a bucket that is installed in the receiver with the ability to interact with the next cartridge in the intermediate compartment, and swivel bonded with her spring-loaded legs, having the opportunity to interact with the tracing curvilinear groove on the outer surface of the barrel as it moves back and forth. The percussion mechanism includes a spring-loaded firing pin movably mounted in the housing and having a slot for engagement with septula; rod platoon, movably mounted in the housing with the possibility of interaction with the lower shoulder Ricany on an axis in the housing, performed in the upper forked end in which the axis has a hinge having a front corner beveled for cooperation with mating angled bevel on septile; spring-loaded sear, accommodated in the housing for movement across the axis of the striker to communicate the upper part with the slot of the striker and the lower part with an angular bevel to interact with the hinge in the trigger.

In the extreme forward position of the barrel is staging drummer in fighting trim. The design of the firing mechanism due to the presence of the kinematic connection between the barrel, the rod cocking lever cocking, trigger and septula allows the shot to divide whispered and drummer) only in the extreme rear position of the trunk. However, this design of the weapon increases the longitudinal dimensions and complicates it.

Known repeating arms (2) containing a movable barrel, receiver box, body, butt, nastolnyy store with cut-off, the trigger mechanism, the locking Assembly, hinged cover, pivotally mounted on the upper part of the casing and provided with two spring-loaded symmetrically arranged on the sides of the cover latches to fix Eske interoperable his front shoulder with the shoulder of the barrel, the mechanism of extraction is made in the form of a spring-loaded lever, pivotally mounted on the rear shoulder of the feeder with the ability to interact with another patron at the exit of the store or with the last emitted by the sleeve.

Cover latch located on one axis across the cover. Between them is a spring.

For charging the gun, you must open the cover, why the unfixing of its housing by pressing the fingers on the latch (compressing the spring). After it is released is pivoted cover and gear store ammunition. When the last cartridge is located at the exit of the store, and its rear end is in contact with the mirror housing. Then the lid is closed. When the lever mechanism of extraction falls to the canvas liner to the last bullet, spinning its torsional spring. When fully closing the lid fixing it latches with spring latches.

Before shooting, you need to distort the barrel back and forth. When the movement of the trunk forward, in the end, the protrusion of the barrel affects the front shoulder of the carrier, swinging it around an axis. The tail part of the rear shoulder of the follower cooperates with the sleeve and Tuscaloosa to fire.

After firing the last cartridge lever mechanism of extraction from a horizontal position becomes a torsional spring in a vertical position, since the store no ammo (in a horizontal position it holds the cartridge located in the store and in contact with the mirror housing). The last release liner is made by the lever (while the other sleeve, except the last, are recorded another cartridge, cut on the line of the trunk).

For reliable ejection of the last cartridge you want the size from the axis of rotation of the cover to the working end of the lever mechanism of extraction at the moment of contact with lever blade liner was smaller than from the axis of rotation of the cover to the flange of the sleeve. Only in this case the lever reaches its working end in the flange of the sleeve and will release liner.

For reliable closing of the cover it is necessary that the working end of the lever is not resting against the flange of the cartridge case of the cartridge, located at the exit of the store, i.e., the dimension from the axis of rotation of the cover to the working end of the lever must be greater than the size from the axis of the cap to the flange sleeve.

However, in the prototype when the cover is closed is uticaria working end of the lever in the flange sleeve (jamming). It & rsquo shoulder fully deployed by the spring relative to the plane of the cover. The size from the axis of rotation of the cover to the working end of the lever has the lowest value. To increase the above-mentioned size and to exclude uticaria lever in the flange is necessary before closing the lid to deploy the rear shoulder of the carrier, pushing him to the plane of the cover. This complicates the operation of the weapon and increases the time of charging, which reduces the operational characteristics of the weapon.

The present invention is directed to a solution to simplify the loading process, by eliminating the need for adherence lever or the rear shoulder of the carrier arm when the cover is closed after equipment store ammunition.

The problem is solved in that small multiply charged the weapon containing the movable barrel, receiver box, body, butt, nastolnyy store with cut-off, the trigger mechanism, the locking Assembly, hinged cover, pivotally mounted on the upper part of the casing and provided with two spring-loaded symmetrically arranged on the sides of the cover latches to fix it in the housing, the carrier is made in the form of a spring-loaded duplicator lever pivotally mounted on the cover with the possibility of its interaction paradebingo on the rear shoulder of the feeder with the ability to interact with another patron at the exit of the store or with the last throw of the sleeve,

each lid latch provided with a hook, made in the form of area with horizontal and vertical shelves;

on each side of the rear shoulder of the carrier formed by the two longitudinal protrusion;

- latch installed on the cover with the possibility of the interaction of the hooks with the corresponding protrusions of the rear shoulder of the carrier when the cover is open.

The technical result is achieved by the design, in which when the cover is opened, and then when closing the lid, rear shoulder of the follower is pressed against the plane of the cover hooks made Toolless cover. The size from the axis of rotation of the cover to the working end of the lever in the moment of touching the lever cartridge, located at the exit of the store, increased compared with the prototype, and uticaria end of the lever in the flange of the liner does not occur.

The essence of the invention is illustrated by the following drawings:

Small repeating arms has a housing 1 (Fig.1) mirror 2. With the case still connected to the receiver box 3, which is made guides. On the longitudinal guides box set barrel 4, which is able to move longitudinally on these projections within the slots of the barrel. On the housing is rigidly fixed nastolnyy store 6 and the butt 5. The case contains a firing mechanism and a locking Assembly. In the case of the hinge (with axis 7) installed removable cover 8. The cover is provided with two latches 9 and 10 (Fig.1, 4) symmetrically positioned on each side of the cover. Between them the spring 11 (Fig.3). Latches are used to secure the cover in the housing. On the cover hinge (with axis 12) is the carrier 13 (Fig.1, 2), biologiste with the tab 15 of the barrel, when the trunk is in the front position. On the rear shoulder of the carrier 13 of the hinge (with axis 16 (Fig.1, 2) the mechanism of extraction, which is made in the form of spring-loaded by a spring 18 (Fig.4) of the lever 17. The lever has the opportunity to interact with another patron at the exit of the store or with the last emitted sleeve. Each of the two latches 9 and 10 provided with a hook. The latch 9 is equipped with a hook in a corner with horizontal 21 (Fig.3) and vertical shelves 22. The latch 10 is equipped with a hook in the form of area 23 with horizontal and vertical shelves 24. The latches are mounted on a cover interoperable with corresponding protrusions (19 and 20 of Fig.4) the rear shoulder of the carrier when the cover is open. While the carrier is held hooks latch from turning under the action of its spring 14.

Runs small repeating arms as follows.

For equipment store leans back cover. What is raspikirovki cover with the housing by pressing on the tabs 9 and 10 fingers. When this is compressed spring 11 (Fig.7), hooks and latches are located under the longitudinal ledges 19 and 20 (Fig.4) feeder. When the pivoting cover, the hooks hold the carrier (through program spring 14 (Fig.1). After pivoting the cover is made equipment store ammunition. When the last cartridge is located at the exit of the store (Fig.5, 6). Then the lid is closed.

When complete close the lid of the projection 25 (Fig.1) feeder 13 rests on the ledge 15 of the barrel and the shank of the carrier is lifted relative to the hooks of the latches, as shown in Fig.7. The latches are released and under the action of its spring 11 to return from bogatogo position to the initial position (Fig.3). The lid is latched in the latch case.

In the proposed design, in the tilted position of the cover, the size from the axis of rotation of the cover to the working end 26 (Fig.6) of the lever 17 in comparison with the prototype more (Fig.5, 6).

Moreover, the larger size from the axis of rotation of the cover to the flange of the sleeve (Fig.6). Therefore, the working face 26 of the lever is lowered behind the flange of the cartridge case of the cartridge, located at the exit of the store. The lid closes freely without jamming of the lever 17.

When the distortion of the barrel back and forth the cartridge, located at the exit of the store, served in the trunk, and in its place is another round from the magazine.

When the trigger is pulled, is shot. The barrel with the reuleaux all cartridges last sleeve is released by the lever 17 (Fig.2), then again saddled the store, and the weapon is ready for the next shot.

The described technical solution has simplified the process of loading arms by eliminating the need for adherence hand feeder in concatenated with lid position. This led to the improvement of weapons.
