Reflex sight having modular hood

Abstract

A target sight system includes a base portion with a gun-mounting interface allowing the sight to be firmly fastened to a shooting device. The base also includes a power supply, a target light generator, and a light-passing surface through which the target light passes between the target light generator and a target. The sight system also includes a cover that is detachably removable from the base portion.

Description

BACKGROUND

Reflex type gun sights provide a shooter a quick and easy way to sight a target compared to conventional iron sights. Reflex sights can be open-type, which typically include only a single lens, or closed type, which typically include at least two lenses enclosed by a tube. Generally, shooters may prefer an open reflex sight when targeting in low light conditions, and a closed reflex sight when in brighter conditions, although various shooters may prefer either type in various situations. It is relatively difficult, however, to change from one reflex type to the other, as changing reflex sights generally requires removing the installed sight from the gun and re-installing the other type.

Embodiments of the invention address these and other limitations of the prior art.

DETAILED DESCRIPTION

Embodiments of the invention may include one or more modular shrouds, which may be installed and removed by the shooter. FIG. 1 is a front perspective line diagram of an open reflex sight 100 that may accept one or more removable shrouds according to embodiments. FIG. 2 illustrates a compact shroud 120 ready to be mounted to the sight 100. The compact shroud 120 includes a bar 122 that is sized and shaped to engage with a slot or groove 102 located on a lower part of the sight 100. First, the user aligns the bar 122 with the slot 102 as illustrated in FIG. 3. Then the user rotates the free end of the compact shroud 120 toward the firearm to the closed position, as illustrated in FIG. 4. The compact shroud 120 may be then secured with one or more fasteners 124, such as a screw or pin to retain the shroud in place. In other embodiments the shroud 120 may be somewhat flexible and include one or more projections that align with one or more recesses in the sight 100 mount. As the user rotates the compact shroud 120 into position, the projections snap into place, held by the rigidity of the shroud material. Once mounted, the compact shroud 120 is in position to partially cover the reflex sight 100, providing mechanical protection as well as blocking some of the light from entering the sight.

In other embodiments the reflex sight according to embodiments of the invention include an installable rear window 150, effectively converting the open reflex sight of FIG. 1 into a closed reflex sight.

FIG. 6 illustrates a separate rear window 150 that is mountable to the sight 100, that, when mounted, converts the open reflex sight of FIG. 1 into a closed reflex sight. In this embodiment the rear window 150 has an overmolded gasket 152. When installed, the gasket 152 seals the back of the open sight 100, turning it into an enclosed reflex sight. As described above, some shooters prefer closed sights to open ones. After the rear window 150 has been installed, as illustrated in FIG. 9, a full sized shroud 170 may be installed to cover the enclosed reflext sight 100, as illustrated in FIGS. 8-8. The full sized shroud 170 installs in the same manner as the compact shroud 120 described above.

This written description makes reference to particular features. It is to be understood that the disclosure in this specification includes all possible combinations of those particular features. For example, where a particular feature is disclosed in the context of a particular aspect, that feature can also be used, to the extent possible, in the context of other aspects.

Although specific aspects of the disclosure have been illustrated and described for purposes of illustration, it will be understood that various modifications may be made without departing from the spirit and scope of the disclosure.
