Abstract
An adjustable laser beam sight comprises a supporting plate and first, second and third serially arranged and rotationally coupled levers mounted on the supporting plate by two pivots. The first pivot rotationally couples the first lever to the supporting plate and the second pivot rotationally couples the third lever to the supporting plate. A laser beam emitting device is attached to the first lever. Rotation of the third lever, acting through the second lever, imparts a change in direction of the first lever and the laser beam. A range scale with its reference center substantially at the second pivot is provided on the supporting plate. An indicator on the third lever moves across the range scale as the third lever is moved to adjust the aim of the laser beam, thereby indicating a range setting.
