发明名称 Adjustable crosshair sight for archery bow
摘要 An adjustable crosshair sight for archery bows comprises a frame in which a plurlity of horizontal wires are mounted in parallel spaced relation such that the vertical distance between adjacent wires can be varied. A vertical wire is mounted in the frame bisecting the horizontal wires, thereby forming a series of vertically spaced crosshairs within the frame. The horizontal wires provide a series of range references to the archer while the vertical wire provides a windage reference. The frame is movably mounted on the bow such that the crosshairs are in the line of sight of the archer when he is in position to shoot and the horizontal distance between the frame and the bow can be adjusted, thereby varying the distance between the vertical wire and the bow and providing a sideways or windage adjustment in the sight.
