Problems solved by technology

Shooting in low light situations makes front sight acquisition and sight alignment more of a challenge.
They are also favored by the military for critical applications where illumination of the glow-in-the-dark sort is desired but a powered light source may not be available.
Prior art self-powered light sources used radium paint, which posed health risks.
As the tritium component of the lighting is expensive, manufacturers try to use as little as po...

first embodiment

[0034]Turning now to FIGS. 2a-5, in accordance with the present invention, a first embodiment front sight is illustrated in FIGS. 2a-2d; front sight assembly 100 includes a source of illumination such as self-luminous tritium vial 102 encased in a sight housing 104 and the visible (or proximal) end of the tritium lamp 106 is surrounded with an annular surface 110 coated with non-radioactive photo-luminescent material, preferably within a counterbore such as circular counterbore 112, defined in the front sight assembly's proximal surface.

second embodiment

[0035]A second embodiment is illustrated in FIGS. 3a-3d, wherein front sight assembly 200 includes a source of illumination such as self-luminous tritium vial 102 encased in a sight housing 204 and the visible or proximal end of the tritium lamp 106 is surrounded with a square-shaped surface 210 coated with non-radioactive photo-luminescent material, preferably within a counterbore such as square counterbore 212, defined in the front sight assembly's proximal surface.

[0036]The tritium lamp feature of sight assembly 100 or 200 will provide a constant, substantially perpetual self powered ‘glow’, that is visible in low light environments while the surrounding brightly colored photo-luminescent material-covered surface (110 or 210) will be highly visible in daylight and, after storing energy from a secondary source, highly visible in low-light environments.

[0037]The photo-luminescent material surrounding the tritium can be seen to the user whether it is ‘charged’ or not charged, based ...

Abstract

A front sight assembly includes a self powered substantially permanent light source such as tritium source carried within a bore defined in a housing, where the housing preferably defines a structure symmetrically aligned along a central plane, where the bore carrying the light source has a central axis that lies within or parallel to the housing's central plane. The sight assembly housing terminates proximally in a proximal surface that faces the user when mounted on a firearm or other instrument. The sight assembly housing's proximal surface further includes a region surrounding or defining a periphery around the light source which is coated with, laminated with or altered to define a region of photo-luminescence that is substantially concentric with the center of the visible portion of light source.

Description

PRIORITY CLAIMS AND REFERENCE TO RELATED APPLICATIONS [0001]This application claims priority to related and commonly owned U.S. provisional patent application No. 61 / 136,776, filed Oct. 2, 2008, the entire disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002]1. Field of the Invention[0003]The present invention relates to sights and, more particularly, to sights adapted for use in low-light environments on firearms and other instruments.[0004]2. Discussion of the Prior Art[0005]For purposes of nomenclature and as an example of one type of firearm, FIG. 1 illustrates a Glock model 17 pistol. When using or shooting a pistol, the user grasps grip frame and aims by aligning a notch or aperture included as part of a rear sight with the distal front sight, thereby pointing the pistol's muzzle at a target. The front sight is usually an upwardly projecting protuberance mounted at or near the muzzle or distal end of the pistol's barrel or slide. An importa...
