Abstract

A device for fast reticle adjustment of a sighting device is described, which is provided with a rotatable safeguard against unintended adjustment and has tactile and visual indicating means for the locked and unlocked position of the safeguard.

Claims

1. Device (1) for fast reticle adjustment of a sighting device of a telescopic sight in which, with the aid of a rotatably mounted setting knob (26), an actuating drive (2) mounted such that it can be displaced in the axial direction acts on the adjusting unit of the sighting device, characterized in that the setting knob (26) is provided with a safeguard (21) against unintended adjustment that can be rotated through 90°

, wherein the safeguard (21) has tactile and visual indicating means (23, 24) for a locked position and an unlocked position of the safeguard.

2. Device (1) for fast reticle adjustment according to claim 1, characterized in that the device (1) is arranged on the top of an intermediate tube connecting the objective and eyepiece of the telescopic sight when in use, and the safeguard (21) is formed by a control wheel (21), which, for the tactile indication in the locked and unlocked positions, arranged offset by 90°

, has detent torques that can be felt, and, for the visual indication of the respective control wheel positions, locked and unlocked symbols (24, 23) are arranged offset by 90°

on the outer circumference of the said control wheel (21) and, in the respective control wheel position, face the eyepiece side of the telescopic sight.

3. Device (1) for fast reticle adjustment according to claim 2, characterized in that the setting knob (26) has on a circumferential region a scale (27) indicating the axial position of the actuating drive (2), which is enclosed in a concealing manner by a sleeve-like edge region of the control wheel (21).

4. Device (1) for fast reticle adjustment according to claim 3, characterized in that the respectively currently set axial position of the control wheel (2), both in the locked and in the unlocked position of the control wheel setting, is visible on the scale (27) through window-like openings (25) in the sleeve-like edge region of the control wheel (21), wherein one window-like opening (25) is arranged in the region of the locked symbol (24) and a further window-like opening (25) is arranged in the region of the unlocked symbol (23).

5. Device (1) for fast reticle adjustment according to claim 1, characterized in that an axially displaceable annular detent wheel (19) arranged to be fixed rotationally with respect to a mounting base (15) is provided with an end toothing system (28) and a movement thread (20) integrally molded on the outer circumference, which meshes with a corresponding movement thread (22) on the inner circumference of the control wheel (21).

6. Device (1) for fast reticle adjustment according to claim 5, characterized in that the axial displacement of the control wheel (19) is effected by a rotational movement of the control wheel (21) into the locked or unlocked position (24, 23).

7. Device (1) for fast reticle adjustment according to claim 6, characterized in that, in the locked position (24), the end toothing system (28) of the detent wheel (19) can be brought into engagement with a corresponding flat toothing system (29) on the setting knob (26).

8. Device (1) for fast reticle adjustment according to claim 1, characterized in that the setting knob (26) has a click detent (6, 7, 8) for the stepwise adjustment of the actuating drive (2).

9. Device (1) for fast reticle adjustment according to claim 8, characterized in that the click detent (6, 7, 8) is provided on a rotatably mounted threaded drive piece (4) connected to the setting knob (26), wherein, in order to adjust the actuating drive (2), the threaded drive piece (4) has an internal thread (5), in which an external thread (3) of the actuating drive (2) engages.

10. Device (1) for fast reticle adjustment according to claim 9, characterized in that the actuating drive (2) is mounted in a slot-like cutout in the mounting base (15) so as to be fixed against rotation, so that a rotational movement of the threaded drive piece (4) effects an axial displacement of the actuating drive (2).
