Abstract

FIELD: air guns. SUBSTANCE: spring-loaded shaped ring 10 is installed on compression cylinder 3 located under barrel extension 2 for limited turning. In the initial position cocking lever 6 turns ring 10 counter-clockwise, as a result, spring 11 of ring 10 gets compressed, and arm 12 of bolt 7 gets released from pressure of ring 10. The gun can be loaded with a bullet and the barrel can be locked with bolt 7. At a withdrawal of lever 6 spring 11 turns ring 10 clockwise, ring 10 presses arm 12 of bolt 7 and turns the latter until handle 8 comes out of lateral groove 13 of barrel extension 2. Bolt 7 moves backward under the action of its spring. After piston 4 of cylinder 3 is cocked, cocking lever 6 is returned to the initial position, and the gun is loaded. EFFECT: improved design. 2 cl, 6 dwg

Description

 The invention relates to pneumatic sports weapons and is a pneumatic spring rifle.

 Known air rifle containing a barrel with a receiver, compression cylinder with a piston, trigger, cocking lever, bolt with a handle and a box. The cocking of the piston and the trigger of the rifle is carried out by the cocking lever, and the bolt is pulled back to the rear position for loading the bullet with a spring after turning it manually by the bolt handle until it leaves the transverse groove in the receiver. The design of the rifle does not exclude the possibility of an arbitrary shot in the case of cocking the piston after loading and closing the shutter.

 The objective of the invention is to increase the operational properties and safety in the handling of weapons by eliminating the additional movement of the shooter's hand when the bolt is retracted back and providing the possibility of locking the barrel only after closing the cocking lever.

 The problem is solved in that the air rifle containing a barrel with a receiver, a compression cylinder with a piston, a trigger, a cocking lever, a bolt and a box, is equipped with a shaped spring ring placed on the compression cylinder with the possibility of limited rotation and interaction with the bolt and lever cocking. The shutter may be made with a protrusion for interaction with a figured ring.

 In FIG. 1 shows an air rifle; in FIG. 2 same, top view; in FIG. 3 shutter position before loading a bullet; in FIG. 4 the same before the shot; in FIG. 5, view A in FIG. 4, the spring-loaded ring is rotated by the cocking lever counterclockwise and does not interact with the protrusion of the shutter; in FIG. 6 the same, the interaction of the spring-loaded ring with the protrusion of the shutter when opening the cocking lever.

 The air rifle contains a barrel 1 with a receiver 2, a compression cylinder 3 with a piston 4, a trigger 5, a cocking lever 6, a bolt 7 with a handle 8 and a box 9. A figured ring 10 spring loaded with spring 11 is mounted on the compression cylinder 3 with the possibility of rotation. On the shutter 7, a protrusion 12 is made for interaction with a spring-loaded figured ring 10. A compression cylinder 3 with a piston 4 is placed under the receiver 2.

 Air rifle works as follows.

 When the cocking lever 6 is retracted (turning it clockwise, Fig. 2), the piston 4 and the trigger 5 are cocked, while the figured ring 10 is released, which, under the action of the spring 11 (Figs. 5 and 6), rotates and pressing the tab 12 of the shutter 7, rotates the latter until the handle 8 exits from the groove 13 of the receiver 2 (Fig. 3). After that, under the action of the spring 14, the shutter 7 moves to the rear position, while freeing up the window 15 for loading the bullet. Then cocking lever 6 (Fig. 5) is returned to its extreme forward position, while it rotates the figured ring 10 counterclockwise, thereby eliminating the possibility of contact of the protrusion 12 of the shutter 7 with the figured ring 10 when locking the barrel 1. The bullet is placed in the window 15 (Fig. 3) and send the shutter 7 to the barrel 1. Simultaneously with the reloading of the bullet and turning clockwise, the shutter 7 locks the barrel. The rifle is preparing for a shot. After the shot, the cycle repeats.

 Locking the bolt 7 of the barrel 1 until the cocking lever 6 is completely closed is excluded, since the figured ring 10 under the action of the spring 11 rotates the bolt 7 each time until its handle 8 leaves the groove 13 of the receiver 2, after which the spring 14 opens the bolt 7.

 In the proposed rifle, even if there is a bullet in the barrel bore and the cocking lever is closed with the trigger pressed, only the piston is disrupted and the compressed air comes out through the open loading window of the receiver. The bullet remains in the barrel, thereby increasing the safety of weapons.
