Abstract

An aiming device for match weapons comprises a body with a backsight installed thereon, the body being fastened to an axle whose ends are installed in the openings of the base with a provision made for rotation and reciprocating movement by means of screws located in the body and used for vertical and horizontal corrections. Installed in the body is a mechanism for retaining the ends of the axle and the butts of the said screws in constant contact with the base. This mechanism comprises a spring located in the sleeve of the body, and a slope formed on the bottom of the sleeve at the side of the external surface adjacent to an appropriate slope formed in the base. The said mechanism provides for a constant elimination of all clearances in the movable joints of the aiming device in one direction, thereby providing, in turn, reliability and accuracy of operation of the device in the course of its entire service life.

Dependent claims

An aiming device for match weapons comprising:

a base and a body, having a backsight, said body being mounted on said base by means permitting rotatable movement about a pivot axis and translatable movement in a direction parallel to said axis;
a pair of adjustable threaded means mounted on said body and adapted to bear against said base in mutually perpendicular planes for providing vertical and horizontal corrections to said backsight in said rotatable and translatable directions of movement;
the translatable direction of movement of said body and the axis of rotation of said body being perpendicular to the axis of the weapon;
and means for biasing the pair of threaded means into engagement with the base of said aiming device;
said biasing means comprising a generally hollow element slidably mounted in said body, and said element having an open end and a closed sloped end;
a resilient element in said hollow element bearing against said body and the bottom of said hollow element, whereby said closed sloped end of said hollow element is pressed against a mutually cooperatively shaped associated wall surface of said base by the action of said resilient element.
