The invention also relates to a reversing system (60) and a telescopic sight (80) each with such an adjusting device (1).

Description

The invention relates to an adjusting device according to the preamble of claim 1 as well as a reversing system according to claim 8 and a telescopic sight according to claim 9, each with such an adjusting device.

Such adjusting devices are preferably used in precision mechanical devices such as optical instruments, telescopic sights and the like. For example, in DE 297 207 37 U1 describes a telescopic sight with a tubular housing tube which has tube mounts for an eyepiece and an objective (system). In this case, an optical reversing system and a reticle assigned to it are present in a central tube, which is fixedly mounted on a double tube in a mount. In addition, further lenses for correcting various image errors can also be arranged in the telescopic sight, for example achromatic lenses for correcting color errors.

An intermediate image designed by the objective in a first image plane on the objective side is shown enlarged in a second image plane on the eyepiece side. Large magnifications only allow restricted fields of view, which do not provide an overview, especially at short distances allow a larger image section. In order to be able to target these objects effectively, the state of the art provides a variable magnification, the so-called zoom. In addition, the targeted object is shown reversed and upside down in the first image plane on the objective side and must therefore be erected. A reversing system within the telescopic sight is therefore used to straighten the image.

On the outside, at least two adjustment towers are attached at circumferential intervals of 90 degrees, which have a locking ring or an adjusting cap to adjust the reticle according to the target distance and wind.

In addition, an adjusting ring is provided, through the center of which the optical path runs and which is rotatably mounted relative to the housing tube. With this adjustment ring, the positions of two lens elements of the erecting system can be adjusted along the optical path, which results in a magnification of the telescopic sight.

The telescopic sight thus has adjusting devices in the form of the two adjustment towers for adjusting the reticle and also in the form of an adjusting ring for setting the magnification. The settings are all made independently based on calculations, tables and empirical values of the shooter. This can quickly lead to errors.

Another problem is darkness, because then the selected setting cannot be read on the existing scales.

Depending on where the reticle is arranged along the optical axis, the selected magnification has an influence on its appearance. This can lead to very strong or very weak line widths, for example. In addition to a target mark for aiming at a target object, the reticle can also have various scales, text information and other optical aids at a distance from the target mark. If the center of the target mark is now enlarged, such components slip to the visible edge or beyond. Accordingly, these are then no longer available. In the case of different magnifications, different components or target marks may also be desired.

The aim of the invention is therefore to provide an adjusting device as well as reversing systems and telescopic sights that support the detection of settings by the operator and / or simplify operation, the solution being intended to cause low mechanical complexity and low costs. In addition, the solution should remain easy and convenient to use and have a long service life.

Main features of the invention are given in the characterizing part of claim 1 and in claims 8 and 9. Refinements are the subject of claims 2 to 7 and 10 to 14.

The invention relates to an adjusting device for the mechanical adjustment of components that can be coupled to the adjusting device, in particular for adjusting a magnification or a reticle device of a telescopic sight, comprising an adjusting element which, for mechanical actuation of the adjusting device by a rotational movement, can be rotated around a rotation axis on a base part is mounted, wherein the adjusting device has an angle sensor for detecting the angle of rotation.

The actuating device, which has hitherto acted mechanically, is thus recorded according to the invention by a sensor-based recording of the angle of rotation. This sensory detection can supplement or even replace the manual detection of the setting by the shooter, for example by visual or haptic testing. Data recorded by sensors can also be used automatically, for example by transmitting the recorded value to a ballistics computer. To detect the angle of rotation, not only degrees should be understood, but all parameters that correlate with such degrees. These include, for example, electrical sensor values such as resistance values and voltage values. The adjusting element can be, for example, an adjusting ring or an adjusting cap.

According to a special embodiment of the adjusting device, it is provided that the angle sensor has a potentiometer with a resistance element and a sliding contact that can be moved along the resistance element, and that the adjusting device has an evaluation device, a resistance value of the potentiometer (indirectly or directly) with the angle of rotation between the adjusting element and the base part is correlated, and the evaluation device is configured to evaluate the resistance value.

The resistance of the resistance element changes depending on the angle of rotation, so that a position of the movable sliding contact can be closed based on a measurement of the resistance or also a voltage on the resistance element. Its position in turn correlates with the angle of rotation between the setting element and the base part. By means of a calibration, the angle of rotation between the setting element and the base part can accordingly be inferred in order to optionally determine a set parameter. Alternatively, the determination of the angle of rotation can be skipped and the set parameter can be deduced directly from a correlation. Alternatively, procedurally speaking, it could even be used skip any determination and instead directly calculate a setting parameter that would be output accordingly for setting.

For use apart from stationary power sources, the evaluation device can have an energy store, in particular a battery or an accumulator.

According to a further development of the adjusting device, the resistance element is arranged on one of the group of base part and setting element, and the sliding contact is arranged on the other of the group of base part and setting element. This allows the relative position between the base part and the setting element to be recorded easily.

The resistance element is preferably arranged in a rotationally fixed manner on one of the group of the base part and the setting element, and the sliding contact is arranged in a rotationally fixed manner on the other of the group of the base part and the setting element. This results in a simple and reliable mechanism.

Particularly preferably, the resistance element is arranged on the base part and the sliding contact is arranged on the setting element. This means that additional electronics can be connected to the resistor element without complicated interfaces. Only the sliding contact, which does not require any cable connections, is a movable component.

A further development of the actuating device provides that the evaluation device is arranged non-rotatably relative to the resistance element. A wired connection between the evaluation device and the resistance element can be implemented in a correspondingly simple manner.

An advantageous embodiment of the adjusting device is achieved when the resistance element is curved along a circular path around the axis of rotation. In this way, the angle of rotation can be detected directly and the center of the adjusting device is free for, for example, mechanical adjusting elements, as are typical in lateral adjustment towers, or for an optical path, as it typically runs through an adjusting ring to change the magnification.

According to a special embodiment, the resistance element extends curved by an angle along a circular path around the axis of rotation, the angle being preferably at least 45 degrees, more preferably at least 90 degrees, even more preferably at least 130 degrees and particularly preferably at least 180 degrees, and where the Angular dimension is preferably at most 359 degrees, more preferably at most 330 degrees, even more preferably at most 310 degrees and particularly preferably at most 300 degrees. In order to the angle of rotation sensor can be integrated compactly into the actuating device. Alternatively, however, designs would also be conceivable in which the angle of rotation sensor can detect an angle of rotation of more than 360 degrees.

Incidentally, the limited angle of rotation should be smaller than a detection range of the angle sensor. In this way every possible angle of rotation position can be recorded. In addition, damage to the angle sensor is avoided.

Furthermore, it is advantageous if the rotation angle is limited by stops between the setting element and the base part. This is because stable structures can be provided for the attacks here.

In a special case of the adjusting device, it is provided that an optical path with optical elements is formed along the axis of rotation. This adjusting device can then, for example, be part of a telescopic sight or a reversing system.

The invention also relates to an inversion system for an optical system with a first lens element and a second lens element, which are arranged along an optical path, the inversion system having an adjusting device as described above and below, and the adjusting element of the adjusting device in such a way is coupled to the first lens element such that a position of the first lens element relative to the second lens element can be mechanically adjusted by the rotational movement. The angle sensor can therefore be used to infer the position of the first and / or second lens element directly or indirectly, or to infer an optical parameter that correlates with this position. A property of the inversion system should be that an intermediate image designed by an optional lens in a first image plane is imaged erect in the second image plane.

In a particular embodiment of the inversion system, the first lens element is mechanically adjustable relative to the second lens element by the rotary movement in such a way that a magnification can be or is changed. The angle sensor can therefore be used to infer the position of the first and / or second lens element directly or indirectly, or also to infer the magnification set directly or indirectly.

Furthermore, the invention relates to a telescopic sight with optical elements which are arranged along an optical path in a housing tube, the optical elements comprising a reticle, an objective, an eyepiece and an inverting system between the objective and the eyepiece, the optical path being a first Image plane between the lens and the erecting system and a second image plane between the eyepiece and the erecting system. The telescopic sight has an adjusting device as described above and below, wherein the base part is arranged non-rotatably on the housing tube or is part of the housing tube. The component that can be coupled to the adjusting device for adjustment is one of the optical elements, this optical element being coupled to the adjusting device for mechanical adjustment. Furthermore, the telescopic sight has a display device that is designed to output information that depends on the angle of rotation detected with the angle sensor, and / or a control device that is designed to display one or more of the other optical elements as a function of electronically set the angle of rotation detected by the angle sensor.

In this way, the user of the telescopic sight is actively supported in operating the telescopic sight. This either through the information of the display device or the direct adaptation of further settings if the setting is changed with the adjusting device.

According to a more detailed refinement, the optical element which is coupled to the adjusting device for mechanical adjustment can be the inversion system, the adjusting element of the adjusting device being coupled to the inversion system in such a way that the rotational movement results in a position of a first lens element of the inversion system relative to a second The lens element of the inversion system is mechanically adjustable in such a way that a magnification can be changed or changed. According to the invention, the position of the first and / or second lens element can now be inferred indirectly or directly with the angle sensor or on an optical parameter that correlates with this position. By determining the angle of rotation, a corresponding calibration allows in particular the current magnification of the reversing system or, as a result, of the telescopic sight.

Optionally, the display device can have display means that can be read inside the housing tube and / or outside the housing tube. The display means are preferably electronic displays.

In a special embodiment variant, one of the other optical elements is the reticle, the reticle being set electronically as a function of the angle of rotation detected by the angle sensor.

According to the invention it can also be provided that the reticle is adjusted as a function of a specific magnification. An angle sensor is not absolutely necessary for this. Instead, the enlargement could also be achieved, for example, by means of a Determining the positions of the first lens element of the inversion system and / or of the second lens element of the inversion system, for example by means of linear position sensors, for example a linear potentiometer.

According to a particular embodiment, the electronic setting of the reticle as a function of the angle of rotation detected with the angle sensor is an electronic setting of the reticle as a function of the mechanically set magnification. This means that the reticle can be automatically adjusted depending on the magnification.

In particular, the electronic adjustment of the reticle comprises adjustment from the following group:

• a shifting of a target mark of the reticle onto an optical axis of the optical path towards or away from this, wherein a shifting preferably takes place directly into the optical axis; The advantage here is the automatic readjustment when the optical axis is displaced relative to the target mark due to the magnification adjustment;
• shifting at least one graphic element of the reticle on an optical axis of the optical path towards or away from this; The advantage here is that this graphic element is conveniently positioned for the user in accordance with the selected magnification;

• an adjustment of scale divisions; Here, too, it is advantageous that suitable scale graduations can be provided for different shooting distances in order to be able to determine the exact shooting distance.

Optionally, the reticle can be arranged in the first image plane or the second image plane. Depending on which of these image planes the reticle is in, the setting options are of greater or lesser importance.

The invention has particular advantages when the reticle has at least one electronically superimposed graphic element. These can be easily adapted, changed or exchanged electronically in an automated manner. For this purpose, a display device for generating electronically generated image data can be provided. A such can have a beam splitter with which the electronically generated image data can be fed into the optical path. Optionally, the beam splitter can be aligned and configured in such a way that the electronically generated image data are directed directly towards the eyepiece, i.e. towards the viewer. Alternatively, however, a projection can also be cast onto a matt or diffusing screen. The viewer then looks at the graphic visualized there. Such an optional matt or diffusing screen is preferably arranged in the first or second image plane.

In the Fig. 1 and 2 one recognizes an adjusting device from different perspectives, an exploded view being chosen to explain the individual parts. The adjusting device 1 is designed for the mechanical adjustment of components that can be coupled to the adjusting device 1, in particular for adjusting the magnification of a telescopic sight 80. The adjusting device 1 has an adjusting element 20 in the form of an adjusting ring 21 which, for mechanical actuation of the adjusting device 1, is mounted on a base part 10 so as to be rotatable through a limited angle of rotation W about an axis of rotation A for mechanical actuation of the adjusting device 1.

In addition, the adjusting device 1 has an angle sensor 30 for detecting the angle of rotation W. This angle sensor 30 is a potentiometer 31 with a resistance element 32 and a sliding contact 33 that can be moved along the resistance element 32. The resistance element 32 is non-rotatably arranged on the base part 10 and the sliding contact 33 is arranged non-rotatably on the setting element 20. As a result of the latter, the sliding contact 33 rotates along with a rotation of the setting element 20 or the setting ring 21.

The resistance element 32 extends in a curved manner along a circular path around the axis of rotation A, this in particular by an angular dimension that is greater than 210 degrees but smaller than 360 degrees. The limited angle of rotation W is slightly smaller than the detection range of the Angle sensor 30 and is defined in particular by stops between the setting element 20 and the base part 10.

The adjusting device 1 also has an evaluation device 40 which is accommodated in the housing of an eyepiece 93. As a result, the evaluation device 40 is also arranged non-rotatably relative to the resistance element 31. This evaluation device is supplied with electrical energy by means of an energy store in a battery compartment 41 on the housing of the eyepiece 93. A resistance value of the potentiometer 31 correlates directly with the angle of rotation W between the setting element 20 and the base part 10. The resistance value of the potentiometer 31 can be evaluated by means of the evaluation device 40, which is connected to the angle sensor 30 for this purpose. In particular, the resistance changes depending on the angle of rotation W, so that a position of the movable sliding contact 33 can be inferred based on a measurement of this resistance or also a voltage on the resistance element 32. Its position, in turn, correlates with the angle of rotation W between the setting element 20 and the base part 10. By means of a calibration, it is possible to infer the angle of rotation W between the setting element 20 and the base part 10 in order to optionally determine a set parameter. Alternatively, the determination of the actual angle of rotation W can be skipped during its evaluation and the set parameter can be inferred directly via a correlation. As an alternative, any actual determination could even be skipped in terms of process technology and a setting parameter can be calculated directly by means of the evaluation, which would then be output accordingly for setting.

As indicated, in the present case an optical path P with optical elements 90, in particular the eyepiece 93 and the inversion system 60, is formed along the axis of rotation A.

How such an adjusting device 1 is embedded in a telescopic sight 80 can be seen in the assemblies of FIG Fig. 3 and 4th . Here each is shown in Fig. 3 only from the outside and in Fig. 4 in longitudinal section that optical elements 90 are arranged along an optical path P in a housing tube 81. In particular, the outer shape of the housing tube differs between the two different telescopic sights 80 shown, which is why the optical parameters in particular differ for the different lenses, which, however, is irrelevant for the invention. The optical elements 90 include a reticle 91, an objective 92, an eyepiece 93 and a reversing system 60 between the objective 92 and the eyepiece 93 second image plane BE2 between the eyepiece 93 and the erecting system 60. The image planes BE1 and BE2 are of a purely virtual nature, albeit optical elements in or on the Image planes BE1, BE2 can be positioned. An intermediate image designed by the objective 92 in the first image plane BE1 is imaged erect in the second image plane BE2. In this second image plane is the reticle 91, which is partially or completely generated by a digital overlay. In addition to a target mark, the reticle 91 also includes all other information that is displayed in the same plane. For the digital display, in Fig. 4 It can be seen that an electronic display device 95 is arranged to the side of the optical path P and mirrors electronically generated image data into the optical path P with the aid of a beam splitter 94. Optionally, the reticle 91 can be arranged completely in the first image plane BE 1, or components of the reticle 91 can be arranged distributed over the first image plane BE1 and the second image plane BE2.

The riflescopes 80 of the Fig. 3 and 4th have as mentioned an adjusting device 1 according to the illustrations according to the Fig. 1 and 2 . The base part 10 is arranged non-rotatably on the housing tube 81 or part of the housing tube 81, depending on whether the housing of the eyepiece 93 is added or not. The component that can be coupled to the adjusting device 1 for adjustment is the reversing system 60, which is therefore coupled to the adjusting device 1 for mechanical adjustment. The rotational movement of the setting element 20 mechanically sets a position of a first lens element 61 of the inversion system 60 relative to a second lens element 62 of the inversion system 60 in such a way that a magnification is changed. For this purpose, an inner tube of the reversing system has a control cam which is part of a cam gear. At least one of the first and second lens elements 61, 62, but preferably both, are shifted along the optical path P to change the magnification.

Optionally, the telescopic sight 80 can have a display device which is configured to output information that depends on the angle of rotation W detected with the angle sensor 30. This is preferably a magnification value (zoom factor), which is also preferably displayed in the second image plane BE2. Here it is then part of the reticle 91 and can be read within the housing tube 81.

As an alternative or in addition, the telescopic sight 80 can also have a control device 82 which is designed to electronically adjust one or more of the other optical elements 90 as a function of the angle of rotation W detected with the angle sensor 30. This is the reticle 91, which is set electronically as a function of the angle of rotation W detected by the angle sensor 30. By changing the magnification with the setting element 20 and / or further adjustments with a lateral adjustment tower 22 for crosswind correction or a height adjustment tower 23 for adaptation For the shooting distance, the target mark of the reticle 91 can be placed offset from the optical path P, which can be automatically corrected directly by the electronic setting.

As an alternative or in addition to the evaluation of the setting ring 21, the angles of rotation of the adjustment caps of the lateral adjustment tower 22 and / or of the height adjustment tower 23 can also be recorded accordingly.

Above all, if the reticle 91 is arranged in the first image plane BE1 differently from the present embodiment, it is also enlarged when the adjustment ring 21 is used, so that adjustments of the reticle 91 with regard to line widths, a shift of at least one graphic element of the reticle 91 to an optical one Axis of the optical path P to or from this; Adjusting measures and / or scales can be helpful.

The invention is not restricted to one of the embodiments described above, but can be modified in many ways.

All of the features and advantages arising from the claims, the description and the drawing, including structural details, spatial arrangements and method steps, can be essential to the invention both individually and in a wide variety of combinations. <b> List of reference symbols </b> 1 Adjusting device 62 second lens element 10 Base part 80 Rifle scope 81 Housing tube 20th Adjustment element 82 Control device 21 Adjustment ring 22nd lateral adjustment tower 90 optical element 23 Height adjustment tower 91 Reticle 92 lens 93 eyepiece 30th Angle sensor 94 Beam splitter 31 Potentiometer 95 Display device 32 Resistance element 33 Sliding contact A.
