A collimator optic part comprises a condenser lens and a ground-glass plate for visualization of a collimated light beam (10) of an active objective unit and another collimated light beam (7) from an adjusting mandrel. The beam deflection parts are formed as deflecting mirrors/prisms (20, 22) and a beam splitter (21). The optic carriers are guided to guide bars (18). The ground-glass plate exhibits infrared-fluorescent coating. An independent claim is also included for an adjusting arrangement comprising an adjustment apparatus.

Description

The invention relates to a Justierapparat and an adjustment arrangement for targeting means, in particular handguns. Targeting means may be light elements, such as a rangefinder and also rangefinder, visual or near infrared (600-950nm), laser rangefinder or ZEFF (target recognition friend / foe) interrogator laser (1.5μm), which has an additional alignment laser (600-950nm ) to have. Furthermore, the term target means also includes vision systems, such as rifle scopes, red dot sights, holographic visors, sight / grain, folding or Leitervisiere and imaging systems, such as CCD cameras or thermal imagers.

The usual practice of adjustment is to shoot the weapon at effective distance, i.e. at distances of 50-150m. This is done by shooting at a target board. The deviation from the bullet hole to the target mark is used to correct the adjustment. Although this method is sufficiently precise but very expensive.

Instead of a real shot, the weapon axis is also represented by a laser beam. The laser device is located in the weapon barrel and the laser beam is set collinear to the tube axis. The distance between weapon and target plate is usually between 10-20 m. At shorter distances, however, uncertainties of the parallax or a rotation of the weapon have a very detrimental effect on the adjustment accuracy.

The DE 40 03 932 C2 uses the fundamental principle of Justierkollimators, which are displayed by a computer-controlled reticle adjustment the tube axis of the weapon, an emergency visor, a laser rangefinder and a telescope without mechanical fine adjustment and stored in a computer.

The DE 199 35 816 C2 Brings a laser source into a chamber. This emits parallel to the run a laser beam, which is reflected by an object and in the target optics on a detector which precisely aligns the target optics mount. Thus, an automatic system for the calibration of target devices on rifles by means of laser beam is specified.

An adjusting device and a method for aligning a simulator axis of a gun associated with a weft simulator are in the DE 10 2005 054 156 B4 disclosed. A modular adjustment device for parallel alignment of a simulator axis of a weft simulator to the sight line of a firearm describes the DE 10 2009 040 280 A1 ,

A device for checking the adjustment between a gun and the sight line of a target optics with an attached to the muzzle of the gun gun optical radiation device is the DE 36 23 455 C3 removable. In this case, the optical radiation device is formed by the point-shaped light exit surface of an optical fiber.

A completely different principle is that of the collimator, with which the parallelism of optical axes can be measured. Such a device for checking the parallelism of two axes names the DE 39 32 078 .A1 , In order to check the parallelism even at larger center distances, an angle mirror and a plane mirror are provided.

Mention should be the DE 30 34 922 A1 , which deals with an adjustment and testing device for a laser removal system, in particular to parallel alignment of the optical axes of transmitter and receiver to each other and to an optical reference axis. This comprises a collimator consisting of a collimator lens, a beam splitter cube with a reticule, etc. The collimator is arranged in a measuring device formed as a separate unit with its own housing. The optical axis of the collimator can in turn be aligned with the reference axis by means of an adjusting device provided in the measuring device.

Based on the application of the Kollimatorprinzips for adjusting a single, but also several and different target means on a weapon, the invention provides the task of demonstrating a simple but efficient adjustment.

The object is achieved by the features of patent claim 1 and claim 6. Advantageous embodiments are contained in the subclaims.

The invention is based on the idea to create a Justierapparat with a small size and to make this simple and handy. Such Justierapparat also aims to allow adjustment of the target means without special route (trajectory).

This idea is implemented by the use of deflecting mirrors, preferably two, and at least one beam splitter in the Justierapparat, which on the one hand, the compact small size of the Justierapparates is achieved, on the other hand, the representation of the image is made trimmed to the operator, thereby simplifying the adjustment process. The deflection elements may alternatively be beam splitters. Already during production, the deflecting mirrors / deflecting prisms and / or the beam splitters are precisely aligned with each other. Preferably, therefore, pentaprisms are used which require a low adjustment effort. The optics or beam splitters are preferably integrated in adjustable optics carriers. The optics carriers are in turn preferably symmetrically constructed. The distance between the optics carrier to each other can be adjusted individually for each weapon and their target means in a wide range.

To adjust the active and / or imaging target means, a collimated light beam of a Justierdorns and a collimator optics is used, comprising a converging lens and a ground glass for visualizing a collimated light beam of the active target and the collimated light beam of Justierdorns. The collimated light beam of the light source can also be used to adjust the imaging target means.

A small and compact adjusting arrangement with the adjusting device is realized inter alia by providing an adjusting mandrel, which is preferably pushed into the weapon barrel. In the head of the Justierdorns a light source with voltage source or electrical connection is integrated. The collimated light beam is aligned parallel to the mandrel axis (axis) and represents the direction of the tube axis of the weapon. The mechanical fit of the Justierdorns adapted to the caliber of the weapon or adjustable to this. The aiming means to be adjusted is / are connected by at least one holder with the weapon. The adjustment is made by the mechanical (also electrical is possible) Control element on the target means and / or on the holder. Deviations from the parallelism are detected by the adjusting device or the Justierapparat and displayed, for example, an adjuster. - Alternatively, the setting can also be made by motor and computation. - Taking into account the simple function but the mechanical setting is favored.

The light source in Justierdorn may be a laser source, preferably visible, red or green. But it is also an LED with aperture and collimator lens used. If a light bulb is used, this light source can also be used for the IR range.

In addition to the small size, the alignment arrangement is characterized in that the installation dimensions of the target means need not be known exactly because the parallelism of light beams or optical axes is detected directly. Installation tolerances therefore do not adversely affect the adjustment. It can be used to adjust several targeting means of a weapon, both active and visual, both in the visual and in the IR range. An adaptation to the geometric conditions of the weapon is easily possible by the / the movable support.

From the DE 10 2008 062 767 A1 is a mandrel as a recording device for measuring devices, such as an alignment device for a target line, a laser or a camera known. This introduced into the barrel mandrel, the external measuring devices are placed, for example, in front of the gun barrel. Other versions regarding the adjustment itself are not made.

Leupold & Stevens (USA) offers a "Zero Point Magnetic Illuminated Boresighter" that produces a point of light projected towards infinity in the direction of the barrel axis of the gun, which the shooter only recognizes in the crosshairs of its riflescope if its optical axis is parallel to the target The axis of the weapon barrel is the face of the weapon barrel, which must have ferromagnetic properties to hold the device in. The accuracy achievable with the device is sufficient to allow a good pre-set shotgun firing with a few shots reach, but is unsuitable for an adjustment.

The direction of a pipe axis marked by 2 of a weapon 30 is represented by a collimated light beam 7 of a light source 6 ( Fig.1 ). This light source 6 is located in the head 4 of a Justierdorns 3. The Justierdorn 3 is pushed into the barrel 1 of the weapon 30. - Alternatively, an external connection is possible. - The light beam 7 is aligned parallel to mandrel axis 2 '. The mechanical precision causes the mandrel axis 2 'and the tube axis 2 to be parallel. The adjusting mandrel 3 contains a voltage source 5 for supplying the light source 6.

For adjustment, the optical axis 13 of a target means 9 (9a, 9b) should be aligned parallel to the tube axis 2. The aiming means 9 is connected by a holder 8 with the weapon 30. The adjustment of the aiming means 9 is based on whether they actively emit a collimated light beam 10a, such as marking lasers, or whether they are imaging aiming means 9b, such as a rifle scope, camera, thermal imager, red dot sight, or sight / Grain etc.

As in Fig. 2 2, the collimated light beam 10 of an active aiming means 9a and the collimated light beam 7 of the adjusting mandrel 3 are imaged by a converging lens 12 of a collimator optics 11 in its focal plane 15. If the two light beams 10, 7 are parallel, they are imaged in the same point. If, in addition, the optical axis 13 is parallel to the light beams 10, 7, the images A, B take place at the focal point 14 of the condenser lens 12. If the light beam 10 'is not parallel to the light beam 7, the light beam 10' is imaged at point B '. The image is preferably made visible by means of a ground glass 16. This may additionally be coated with an IR-fluorescent material (thin).

A top view and side view of a Justierapparates 40 shows Fig. 3 , The Justierapparat 40 has at least one stable bottom 17 and is provided with a mounting plate 24 and a three-dimensional adjustment 25 connected to an articulated arm and / or flexible arm 26. The Justierapparat 40 also includes one or more guide elements 18, such as rods 18, preferably two, to which a plurality of optical carrier 19 are attached. The guidance of the optical carrier 19 on the / the rods 18 can be done via bushings 27, latching or arresting. The optics carrier 19 are in turn displaceable. The optics carrier 19 may also be mounted on slides (not shown in detail), which are arranged displaceably on a rail. The optical carriers 19 each contain a deflection mirror / deflecting prism 20, 22 or a beam splitter 21 (20, 22), which are precisely aligned by adjusting elements. The optical carrier 19 contains windows 23 for the entry and exit of the light beam. Preferably via a threaded connection / bayonet connection 28, the light source 9c or the collimator optics 11 or an enlarging device 11 'can be attached ( Fig. 4a ).

The Fig. 4a, b, c show the integration of the small-sized adjustment apparatus 40 in an adjustment arrangement 50 Fig. 4a shown is the adjustment for an active destination means 9a, in Fig. 4b and Fig. 4c illustrated is the adjustment for an imaging target means 9b.

For viewing the ground glass 16, a magnifying device 11 ', as in Fig. 4a exemplified used. Thus, the image is additionally enlarged, allowing a finer adjustment. Such a magnification device 11 'may be an eyepiece. The color of the light beam 7 is preferably selected as the complementary color to the light beam 10a of the active aiming means 9a. The color difference makes it easier to detect positional deviations of figures A, B.

Is it an imaging target 9b ( Fig. 4b ), the aiming means 9b is directed toward the window 23 of the deflecting mirror 22. In this case, the optics of the imaging target means 9b acts as the collimator optics 11. The collimated light beam 7 of the Justierdorns 3 is formed in the center of Zielmittelanzeige from when the optical axis 10b of the target means 9b and the deflected light beam 7, ie, the tube axis 2, are parallel to each other. For this application, the use of the ground glass 16 can be dispensed with.

Imaging target means in the IR range can also be adjusted when the light source 6 'in the alignment mandrel 3 is a heat source, preferably an incandescent lamp. Otherwise, as in Fig. 4c represented at the beam splitter 21, a collimated light source 9c, for example, contains a light bulb as a heat source to connect. This is alignable and is adjusted as under Fig. 4a for an active destination means 9a. The light source 9c then supplies the reference beam 10c for the adjustment of the imaging target means 9b (for example IR system). The Justierapparat 40 can be connected via a two- or multi-jointed or a flexible arm 26 with the weapon 30 or a weapons brace (not shown in detail). Alignment may be accomplished by a three-dimensional adjustment 25 on a mounting plate 24 of the jig 40 and arm 26. This alignment takes place in such a way that the image of the light beam 7 on the ground glass 16 of the collimator lens 11 is as central as possible.

Other settings of the adjustment device 40 on the weapon 30, e.g. with tripod or tripod, are possible.
