WEAPON UNIT WITH AIM DEVICE AND METHOD OF ITS ADJUSTMENT Russian patent published in 2015 - IPC F41G3/00 

FIELD: weapon and ammunition.

SUBSTANCE: weapon unit with the aim device contains a bottom machine and a top machine on which a rotary cradle with the weapon and the parallelogram are installed on pins which consist of the machine bracket fixed with reference to the top machine, the lever connected with the cradle, rods and consoles with a land sight installed on it, an antiaircraft sight with a ring grid and an adjusting device for adjustment of vision axes of sights, the land sight is designed as a conic hollow bell extending by the front end towards muzzle part of the weapon and installed on the support by means of the rack, and the ring grid of the antiaircraft sight is installed coaxially to the bell of the land sight and by the internal ring is fixed at the back end face of the bell in such a way that the central projections of the external circle of the front end face of the bell and the external circle of the internal ring of the ring grid are visible from the centre of the structure located on the aiming line as a ring strip of identical width, the adjusting device it is designed as a bracket with bearing platforms on the ends interacting with reciprocal bearing platforms made on the support and the console of the parallelogram by means of adjusting and the fasteners having a possibility of axial movement. Fasteners are symmetrised around the adjusting elements. The ribs connecting raccourcir rings are implemented prominent inside the bell, on the bell end the aim level with the front sight in the bell centre of the aim device is located, holes in bearing platforms of the bracket are made with thread. The method of adjustment of the aim device of the weapon unit consists in adjustment of position of the weapon by combination of the axis of the stock channel of the weapon with the corresponding cross hairs of the reference target by means of the boresighting tube and alignment of the sight line of the aim device with the corresponding cross hairs of the reference target by means of the adjusting device. After adjustment of position of the weapon in the aim device the auxiliary bushing with longitudinal grooves is placed which is entirely implemented as a groove in the centre of the auxiliary bushing, and then backsight is aligned in the auxiliary bushing and the front sight of the aim level of the bell with the cross hairs of the reference target.

EFFECT: simplification of finding of necessary eye position providing an aiming, acceleration of aiming at the target, simplification of exact aiming at small or far targets, increase of vibrostability of fastening of the aim device, improvement of accuracy of adjustment of the aim device, acceleration of sight adjustment.
