Description

The invention relates to the production of small arms, primarily automatic and semi-automatic sports.

When shooting in training or in competitions, the shooter loses time, as well as control over the target, when the store is empty and the need to insert a new one. This reduces both the rate of fire of the weapon and makes the shooting unsafe due to the danger of losing the line of fire, the unexpected occurrence of obstacles on it, etc.

In order to minimize losses in the weapons known in EP 2045562, F41A 19/15, 04.10.2007, it was proposed to position the ergonomic controls of the magazine latch in close proximity to his index and thumb, which allows the shooter to quickly and quickly throw out an empty magazine without changing his position .

However, the disadvantage of this device is that the shooter, having no information about the number of cartridges remaining, must periodically disconnect the magazine, and when the last cartridge is used up, perform manipulations, albeit of a small amplitude, necessary to empty the magazine.

Closest to the proposed one is small arms, containing a mechanism for automatically ejecting an empty store, triggered after the last cartridge leaves the store, but before it is sent to the chamber. The last action in the known solution is made in the process of replacing the store (see US patent 5379541, F41A 17/00, 1995). The mechanism contains a control element, as well as a finger, actuating the tooth, made at the same time with a spring-loaded elevator magazine cartridges and provides self-insertion when a new magazine is inserted. In other words, the mechanism contains a kinematic connection between the working spring of the magazine and the latch that holds the magazine in the working position.

The mechanism for automatically ejecting an empty store is activated in the known device only after the shooter acts with a finger on the control element. This mechanism does not automatically throw out the empty store, but allows the shooter to throw it out in semi-automatic mode by clicking on the control. This circumstance is responsible for the main disadvantages of the known device: firstly, the shooter may not know that the magazine is empty and does not press the control element, and secondly, the automatic ejection of the magazine is necessary at a high rate of fire and is unnecessary, and for some applications and dangerous when firing at significant intervals.

Thus, the technical result expected from the use of the invention is to increase the rate of fire of small arms and safety of shooting, accuracy of shooting and ease of use of small arms due to the automatic ejection of an empty store at a high rate of fire.

The specified result is achieved in that in small arms of increased safety and rate of fire, equipped with an ejected magazine with a working spring and a feeder, which is connected by a kinematic connection with a magazine latch, the kinematic connection is made of two parts, between which a tempo isolation is established.

The essence of the proposed solution lies in the fact that if, in a known device, the magazine ejection mechanism works after the arrow affects the control element and if the store is empty, then it works in the proposal if the rate of fire is maintained and the store is empty. In other words, the magazine is thrown out without the intervention of the shooter under two conditions: firstly, the magazine is empty, and the last cartridge is sent to the chamber or can be sent when a new magazine is inserted, and secondly, the average rate of fire is high, above a given level. To do this, the store feeder is connected to the latch and, when the store is empty, releases the latter, but only if the tempo decoupling (the latter can be performed in various ways, including as shown below in the form of a damped decoupling), ensures the connection of the two halves of this kinematic connection. This, in turn, takes place only at a sufficient rate of fire. Damping the tempo decoupling is advisable for some averaging of the tempo, eliminating the influence of its fluctuations.

The damped temporal isolation can be performed on the basis of a spring-loaded inertial mass, as shown below, or a weight damped by a pneumatic or hydraulic mechanism. You can also use the accelerometer, at the output of which an integrator is installed, which controls the disconnector of the halves of the kinematic connection.

In some cases, for example, when conducting competitions, performing exercises, etc., it is required to provide a minimum reload time for the pistol or a virtually continuous rate of fire. In this case, the safest method is that in which during the reloading the axis of the weapon continues to be in the direction of fire (and reloading is done in a minimum time). The proposed mechanism satisfies these requirements.

If the high rate of fire coincided with the sending of the last cartridge, an empty clip is thrown out of the case, and a new one can be instantly inserted without changing the position of the gun (on the line of fire) and manual sending of the cartridge.

Figure 1, 2 schematically shows an example implementation of the claimed device in two positions. The main elements of the device are (Fig. 1, 2) magazine 1 with a latch 2, free traction 3 on the axis 4, the position of which is determined by the springs 5, 6, the second ends of which are fixed in the housing 7 of the small arms. The spring 6 is equipped with a weight 8. The feeder 9 of the cartridges 10 is pressed from below by a working spring 11 (Fig. 1) and is configured to interact with a free rod 3, for example, via a pusher 12 moving in the guide 13 and a rod 14 fixed on the axis 15. The rod 14 is made with the possibility of entering the groove 16 of the free rod 3. The latch 2 is kinematically connected to the free rod 3 through the sector 17 (rigidly) and the rotary element 18.

The device operates as follows. The forces of the springs 5 and 6 are selected so that at a low rate of fire the elements of the device are in the position shown in Fig. 1: the spring 6 with a weight 8 deflects the free rod 3 to the left, the rod 14 is pulled out of the groove 16, the latch 2 keeps the magazine 1 from being pushed out its spring 19 even if the magazine 1 is empty and the last cartridge 10 'is in the chamber, and the feeder 9, as shown in figure 2, moves the pusher 12 in the guide 13 upwards, acting through it on the rod 14.

If the rate of fire is high, the weight of inertia is rejected by the weight 8, compressing the spring 6. The free rod 3 is rotated clockwise on the axis 4, the rod 14 enters the groove 16. Now, if the feeder 9, as shown in figure 2, moves the pusher 12 to guide 13 upward, acting through it on the link 14, the latter will lower the free link 3, which will release the latch 2 of the magazine 1, for example, through the pivot lever 20, releasing the latch 2, allowing it to rotate about the axis 21 (figure 2).

In this example, the kinematic connection and the damped temporal decoupling are made in the form of interacting elements indicated by positions 12, 13; 14, 15; 3, 4, 16; 20, 21, 2, and 5, 6, 8. The actual damped tempo isolation is formed by elements 5, 6, 8, and 14, 16.

The return of the elements to their original state occurs after the installation of a new store: the spring-loaded pusher 12 is lowered, being released from the action of the feeder 9, and all the elements of the device return to the position of figure 1.

Thus, if the fire is fired by separate shots, the store 1 is changed as in conventional weapons by, for example, manually releasing the latch 2. If the shooting is carried out at a high pace, the shooter does not waste time changing the store and is not forced to change the position of small arms for this, store 1 is automatically released.
