Abstract

The invention relates to optical instrumentation, and in particular to designs of optoelectronic sights. The aim of the invention is to increase the accuracy of shooting, simplify the design and reduce its weight. The goal is achieved by installing a translucent lens 3 in a spherical frame 2 in a housing made in the form of a split bracket with the ability to rotate the lens around the center of the spherical frame, coinciding with the center of the reflective surface of the translucent lens. The sight is equipped with dovetail guides with a clamping mechanism in the form of a screw pair for attachment to the weapon. 3 ill.

Description

The invention relates to optical instrumentation, namely to the construction of optoelectronic gun sights,

There are known designs of military weapons equipped with a collimating sight containing a mirror lens, a shaper of the aiming mark and a mechanism for combining the sighting axis of the sight with the barrel axis of the gun.

The disadvantage of these designs is their complexity due to the presence of mechanisms for combining the sighting axis of the sight with the axis of the rifle barrel, the mechanism for introducing lateral wind correction and firing range. When shooting from hunting rifles, taking into account the real situation, the possibility of introducing corrections for changing ranges and changing winds hardly realizes.

Close in technical essence to the invention is an optical sight

for small arms, comprising a collimator optical unit with a translucent optical element, an aiming mark forming unit, a mechanism for adjusting the position of the light source in the focal plane of the optical element, a light source power unit with adjusting the light output of the source, and a mechanism for adjusting the position of the sight axis.

The design drawback of this optical sight is the complexity of the mechanism of combining the sighting axis of the sight with the axis of the barrel of the weapon and the mechanism of movement of the light source, which consists of two sliders, two gears, two axes with flywheels, two locking devices, which reduces reliability and increases the cost of the product.

The aim of the invention is to simplify the design of the optical sight for small arms and increase it by XJ

reliability by reducing the number of components and parts. .,.

This is achieved by that in; an optical sight for small arms containing a collimator optical unit with a translucent; - an optical element made in the form of a semitransparent concave lens of zero optical power, an aiming mark forming unit, a light source power supply unit with adjustable light flux intensity, and a light source moving mechanism and a mechanism for adjusting the position of the sighting axis, the clamps of the sight are introduced to the dovetail type of gun, which provides technologically determined accuracy of the position of the sighting axis whole about the axis of the barrel, and a translucent concave lens mounted in a spherical frame mounted in a split bracket, which makes it possible to rotate the specified lens. Threat around the center of the sphere of the frame, coinciding with the center of the reflecting surface of the translucent concave lens; and provides the ability to accurately snap the sighting axis of the sight to the barrel axis of the gun.

Figure 1 shows a General view of the gun sight, section; FIG. 2 is a view along arrow A in FIG. 1; in Fig. 3 is a view along arrow B in Fig. 1 .; :.

The optical sight for small arms contains a collimation optical unit 1, a spherical frame 2, a translucent concave lens 3 of zero optical power, a power supply 4, an active grade 5 brightness adjustment unit, an active grade 6 "split arm 7, screw 8, clamps 9.

A spherical frame 2, placed in a split bracket 7, the inner surface of which is machined in a sphere, form a hinge. The translucent concave lens 3 is mounted in the frame 2 with the possibility of rotation in the bracket 7.

The device operates as follows.

In order to ensure accurate alignment of the sighting axis of the sight with the gun axis or - to set the desired firing range, it is necessary to unscrew the screw 8, loosening the clamping of the spherical frame 2, and turning it relative to the split bracket 7, set the image of the active mark 6 to the position corresponding to the given firing range and then screw 8 is tightened, fixing the position of the frame 2 with a translucent concave lens 3, and therefore the position of the image of the active brand.

. These operations are carried out during the shooting of weapons.
