DESCRIPTION:
BRIEF SUMMARY
The invention relates to an aiming device for handheld firearms which comprises a rear notch sight and a front sight in which case there are unobstructed gaps between the mutually facing boundaries of the rear notch sight and the front sight, in which case the rear notch sight has an essentially trapezoidal rear notch sight cutout which diverges downward from an upper edge, and the front sight has an essentially triangular outline, whose upper tip, when the weapon is being aimed, bisects the upper side of the trapezoidal rear notch sight cutout, so that an unobstructed gap is formed in each case between the sides of the trapezoidal rear notch sight cutout and the sides of the triangular outline of the front sight.
DE 21 26 068 A discloses an aiming device in which, in various versions, the rear notch sight and front sight have mutually matching (circular, diamond-shaped or X-shaped) contours and thus, when being aimed at the target, form at least two pairs of unobstructed gaps which include an angle between them. A pair of unobstructed gaps is associated with both the horizontal and the vertical discrepancy, so that both discrepancies are perceived in the same way. However, this is actually disadvantageous since, when aiming at the target being pointed at, the pairs of unobstructed gaps lead the eye away from the target toward the angles. On-the-dot aiming at the target is thus impossible. If the target is passed over rather than being aimed at directly, then a considerable part of the target is covered by the large-area front sight, thus impeding target acquisition. This not only delays target acquisition but also leads to aiming errors.
FR-A 342 645 discloses an aiming device of this generic type in which the front sight has a triangular outline and the rear notch sight has a cutout which forms unobstructed gaps or triangles together with the front sight, which disappear when the azimuth aiming errors are very small. Thus, overall, the unobstructed gaps are too narrow to hold a target point, in particular a moving target point, in position during (azimuth) aiming and to guide the eye to the target point, which is considerably further away, at the same time as matching the unobstructed gaps, and to provide an adequate view of the target point. This aiming at the target point and matching of the gaps requires the eye to accommodate alternately at different distances.
AT 379 447 B discloses a U-shaped aiming aid with contrasting colors. However, it surrounds a conventional rear notch sight cutout at a suitable distance. Quick, accurate target acquisition is thus impossible since, owing to the contrast point which is fitted to the front sight at medium height, the view of the eye is not guided to the critical upper edge of the aiming device.
The object of the invention is thus to provide an aiming device which quickly and unambiguously guides the eye to the target while aiming and which at the same time covers the target as little as possible.
As claimed in the invention, this is achieved in that the unobstructed gaps are inclined at about 45 degrees to the vertical, wherein contrast strips are arranged in the upper region of the rear notch sight and of the front sight and entirely or partially line the sides of the trapezoidal rear notch sight cutout and the sides of the triangular outline of the front sight.
As a result of the inclination of the unobstructed gaps at about 45.degree. to the vertical, aiming errors in both the elevation direction and in the azimuth direction have the same influence on the width of the unobstructed gaps and, when accommodating from a short distance (the front sight) to a long distance, the eye is automatically drawn toward the target. The two converging unobstructed gaps which are produced between the sides of the trapezoidal rear notch sight cutout and the sides of the triangular outline of the front sight lead the eye--assisted considerably by the contrast strips--toward the target and, in addition, are used for horizontal adjustment. The contrast strips as claimed in the i
