ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to optical sights, and more particularly to a mounting assembly for an optical sight.
BACKGROUND OF THE INVENTION
Day
ight sights would typically be used by military and law enforcement personnel to aim weapons used in both day time and night time conditions. Typically, a day
ight sight includes an objective lens, a reticle and an eyepiece in series with parallel day and night channels. A channel selector may be used to alternatively direct an image of a target into the day or night channel.
In a day
ight sight, the objective lens and the eyepiece may be telescopic to provide a magnified image of the target. The day channel generally uses ambient light to generate an image of the target. The image may be projected to the reticle during day time use to be viewed by the user. The night channel generally includes an image intensifier to generate an illuminated image of the target. The illuminated image may be transmitted to the reticle during night time use to be viewed by the user. The reticle may include markings for aiming the weapon.
Day
ight and other types of sights are typically mounted to a weapon with integral feet members configured for that specific weapon. Consequently, an adapter must often be used when a sight is mounted onto a weapon for which it was not particularly designed. The adapter is generally mounted directly to the weapon and the sight mounted to the adapter. As a result, adapters generally raise the position of the sight relative to the weapon. The additional spacing between the sight and the weapon may make the sight awkward to use and thus degrade the user's performance with the weapon.
SUMMARY OF THE INVENTION
Accordingly, a need has arisen in the art for an improved mounting system for an optical sight. The present invention provides a mounting system that substantially eliminates or reduces the disadvantages and problems associated with prior sights.
In accordance with the present invention, a mounting assembly may comprise a first foot and a second foot. The first may include a top, a first side and a second opposite side. The top may have a first tab sized to fit a first recess of a sight. The first side may be adapted to engage in a first edge of a rail. A first clamp may be coupled to the second side of the first foot to engage in combination a second edge of the rail. The second foot may include a top, a first side and a second opposing side. The top may have a second tab sized to fit a second recess of the sight substantially normal to the first recess. The first side may engage the first edge of the rail. A second clamp may be coupled to the second side of the second foot to engage in combination the second edge of the rail.
Important technical advantages of the present invention include providing an improved sight. In particular, the sight may be mounted to a variety of weapons without the use of an adapter. Accordingly, the sight may be used on different weapons without raising the sight relative to the weapons.
Still another important technical advantage of the present invention includes providing non-integral members for mounting the sight to a weapon. In particular, the non-integral members allow the sight to be the designed independently of the weapon. Accordingly, the sight may be of a modular design that can be mounted to a weapon with non-integral members configured for that weapon.
Other technical advantages will be readily apparent to one skilled in the art from the following figures, descriptions, and claims.
