AI Technical Summary

Benefits of technology

The present invention provides an adjustable mechanical sighting mechanism with a locking mechanism that can be moved to any selected position for windage adjustment and locked in place to prevent accidental movement caused by vibration, shock forces, or impacts.

Problems solved by technology

The rear blade of the sight mechanism is positioned by the adjustment screws, but cannot be locked against inadvertent movement.

Embodiment Construction

[0020]Referring now to the drawings and first to FIG. 1, an adjustable sighting mechanism constructed according to the principles of the present invention is shown generally at 10. The adjustable sighting mechanism 10 incorporates a sight mounting base 12 having a depending dove-tail projection 14 defining undercut angulated dove-tail surfaces 16 and 18. The dove-tail projection 14 is adapted to be received within a sight mounting slot of a firearm component having a corresponding dove-tail configuration (not shown). As an example, the reciprocating slide of the well known 1911-A1 handgun defines a dove-tail sight mounting slot within which the dove-tail mounting projection of a mechanical sighting device is received in tight fitting relation. Sight mounting crews extend through the reciprocating slide structure and are threaded into the dove-tail mounting projection to secure the sight base in immovable relation with respect to the reciprocating firearm slide. Though the adjustable...

Abstract

An adjustable mechanical sighing mechanism for firearms has a sight blade mount defining an internal passage having first and second outwardly flaring passage end surfaces. An adjustment screw having an external tapered surface is in engagement with the first of the outwardly flaring passage end surfaces. A sight blade structure defines a sight adjustment member having an internally threaded screw passage that receives the adjustment screw. A lock nut is threaded onto the adjustment screw and has an external tapered surface in engagement with the second outwardly flaring passage end surface. The sight blade mount defines a slot through which a support for the sight adjustment member is movable, providing for windage adjustment of the sight blade structure by rotation of the adjustment screw. The tapered surfaces of the adjustment screw and lock nut provide for locking of the sight blade at any desired position.

Description

BACKGROUND OF THE INVENTION[0001]Field of the Invention[0002]The present invention relates generally to sighting mechanisms for firearms and more particularly concerns an adjustable mechanical sighting mechanism for handguns and other firearms. Even more particularly the present invention concerns a mechanical sighting mechanism having a sighting blade member that is adjustable for elevation and windage to control the strike point of a bullet fired by the firearm and is provided with a novel adjustment and locking mechanism to ensure against inadvertent movement of the sight blade member even when the firearm is subjected to the impacts and jarring of prolonged firing, such as during a shooting match or during tactical shooting and firearm handling activities.[0003]Description of the Prior Art[0004]Though it is to be understood that the mechanical sighting mechanism of the present invention is applicable for use with a number of different types of firearms, for purposes of simplicit...
