Patent attributes
A new and useful structure that provides a simple and efficient lens cover for an optical sight, particularly a hooded optical sight. A lens cover structure comprises a lens cover frame, or a pair of lens cover frames, with lens covers designed to cover and uncover the lens openings in an optical sight, particularly a hooded optical sight. Each lens cover is biased toward a covering position in which it covers a respective lens opening in the hood, and is moveable against its bias to an uncovered position in which it uncovers a respective lens opening in the hood. According to a preferred embodiment, the lens covers are configured to be in predetermined orientations relative to the hood, when the lens covers are in their uncovered positions. In addition, a preferred embodiment is designed to enable the lens covers to be conveniently manipulated by the “off hand” (a shooters term describing the hand that is not responsible for fire control). Moreover, a preferred embodiment has a front lens cover configured provide a shade for the front lens opening when the front lens cover is in its uncovered position, and the front lens cover is also configured such that it can be released from its predetermined orientation in the event that a force is applied to the lens cover that might otherwise break or damage the lens cover. In addition, the lens cover structure, according to the present invention, is also designed to enable the lens cover structure to be retrofit to an existing hooded optical sight.
