Description

The device relates to devices for improving the accuracy of shooting from small arms.

It is known that the barrel of a weapon when shooting deviates from the line of sight on the target (aiming line):

- first, due to the occurrence of a rotating moment relative to the center of mass of the weapon when the finger presses the arrow on the trigger of the weapon;

- then due to the overturning moment (the moment of recoil) arising from the shot, as well as due to a change in the center of mass of the system when the bullet moves along the barrel of the weapon.

The impacts are significant. They act mainly on the wrist joints of the shooter. Quite often, for beginners in shooting, the gun falls out of hand.

To reduce fluctuations in the barrel of a weapon, as a rule, devices are used to reduce oscillations of the weapon itself (for example, nozzles with a certain geometry to compensate for recoil, increasing the mass of the weapon to reduce oscillations, etc.) [1, 2].

Arrows-athletes to reduce the oscillations of the barrel of a weapon when shooting use the fixation (immobilization) of the joints with elastic bandages. This allows you to reduce the fluctuations of the shooter's joints, both when aiming the weapon at the target, and during recoil (when the bullet moves along the barrel of the gun barrel) after pulling the trigger.

The purpose of the device is to increase the accuracy of shooting from a personal weapon (for example, a pistol) by reducing the fluctuations of this weapon in the hand (in the wrist joints) of the shooter and to improve the functional and physical capabilities of the fighter.

This goal is achieved by the fact that the proposed device uses controlled displacement sensors and actuators for fixing (immobilizing) the wrist joints arrow

Traditional manipulators - exoskeletons, worn on the human operator and controlled by him, can increase the muscular efforts of a person tens of times. However, these manipulators limit the maneuverability of a fighter while performing functional duties [3, 4].

The proposed device for fixation (immobilization) of the wrist joints arrow consists of sensors of the beginning 1 and end 2 of the movement of the trigger (trigger), information processing device 3, flexible moving devices - actuators of the manipulators 4 with devices of a hard stop 5, the block of reception and transmission of control commands 6 (figure 1).

The operation of the device.

A fighter traditionally directs a weapon at a target. When he pulls the trigger of the gun trigger, the sensor 1 triggers the start of movement of the trigger. The signal from it is processed in the device 3. A signal is sent to the hard stop devices 5 flexible moving devices - actuators of the manipulators 4. The wrist joints are fixed (immobilized) arrow.

After the sensor 2 is triggered, the trigger (trigger) is displaced in the processing device 3, the signal to release the fixation to the actuators is delayed for a while by the movement of the bullet through the barrel of the weapon.

Since the rigid fixation of the wrist joints of the arrow limits the movement of these joints, a lighter body of the fighter can be used to restore the lost shooting line during the shooting.

The device of fixation (immobilization) of the wrist joints of the shooter is carried out according to the commands of the fighter (from motion sensors). In addition, it is obvious that this device can be integrated into a higher order system for controlling the device of fixation (immobilization) of the wrist joints of the shooter according to signals from outside, using the control unit 6 (Fig. 1), in critical cases, when due to fatigue, injury and other difficulties, the shooting task is limited.

Elements of this device can be implemented in the form of:

- sensors of the beginning and end of movement of the trigger mechanism (trigger) in the form of sensor sensors such as micro-accelerometers [7, 8];

- information processing device in the form of microprocessors [9, 10];

- flexible moving devices - actuators in the manipulators in the form of flexible automobile safety belts [3];

- a hard stop device in the form of an automobile safety belt fixation device [3].
