Description

The invention relates to an adjusting device according to the preamble of claim 1 and a rifle scope with one according to claim 12.

Such adjusting devices are preferably used in precision mechanical devices such as optical instruments, rifle scopes and the like. For example, in DE 297 207 37 U1 describes a rifle scope with a tubular housing tube that has tube mounts for an eyepiece and a lens (system). There is an optical reversing system and an associated reticle in a center tube, which is permanently mounted on a double tube in a socket. In addition, other lenses can also be arranged in the riflescope to correct various image errors, for example achromats to correct color errors.

An intermediate image created by the lens in a first image plane on the lens side is imaged enlarged in a second image plane on the eyepiece side. Large magnifications only allow limited fields of view, which do not allow an overview of a larger image section, especially at short distances. In order to integrate these objects effectively In order to be able to take sights, the state of the art provides for a variable magnification, the so-called zoom. In addition, the targeted object is imaged inverted and upside down in the first image plane on the lens side and must therefore be set up. To erect the image, a reversing system is used within the rifle scope.

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

Conventionally, such a locking ring, which can be rotated through a total of around 350°, has a fine detent such that it moves one step further when turned (click adjustment), which changes the point of impact at 100 m, for example by 10 mm. There is a scale on the outer circumference of the adjustment tower from which you can read the correction made. Depending on the division, for example, every second click is marked with a white line, while every tenth click is indicated by a number.

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. This adjustment ring allows the positions of two lens elements of the reversing system to be adjusted along the optical path, thereby increasing the size of the riflescope.

The rifle scope therefore has adjusting devices in the form of the two adjustment towers for the reticle adjustment and also in the form of an adjustment ring for the magnification adjustment. The settings are all made independently based on calculations, tables and experience of the shooter, which also depend on the weapon and ammunition used. This can quickly lead to errors. In addition, precise and quick setting changes are difficult.

The aim of the invention is therefore to provide an adjusting device and a rifle scope that support the adjustment of the rifle scope 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 comfortable to use and have a long service life.

Out of US 2008/0289239 A1 A rifle scope with an adjustment turret is known, in which a stack of three indicator rings is arranged between an upper part and a base part. The indicator rings each have a position marking that is visible from the outside as well as a marker tooth structure pointing inwards, with which they sit non-rotatably on a gear structure of the base part. In order to adjust the indicator elements in the circumferential direction, the upper part must be detached from the base part and the indicator rings must be pulled down axially from the base part. The teeth can then be pushed back onto the base part at the desired angle of rotation.

US 2004/0144013 A1 teaches in an adjustment tower to clamp a stack of indicator elements in the form of ring-shaped disks, each with an angled indicator tip, between an upper part and a base part of the adjustment tower. So that an indicator element arranged in a first plane does not rotate an indicator element arranged in the neighboring plane when rotating, an intermediate disk is inserted in the intermediate planes between two adjacent indicator elements, which is mounted in a rotationally fixed manner. The indicator tips of the indicator elements are arranged on the outside of the adjustment tower. A number is shown on the tip of the indicator. This means that the indicator elements arranged in different levels can be rotated to a limited extent on a core element when the associated clamping screws are loosened. The intermediate disks in the intermediate levels are each guided in a rotationally fixed manner on the base part, which means that there are no direct friction surfaces between the indicator elements. The indicator tip of each indicator element can be freely adjusted in the area between the neighboring indicator tips by turning.

Main features of the invention are specified in the characterizing part of claim 1 and in claim 12. Refinements are the subject of claims 2 to 11 and the description.

1. (a) ist die Befestigungsnut parallel zur Rotationsachse ausgerichtet; und/oder
2. (b) sind die Befestigungsnut und jedes der Indikatorelemente in einer gemeinsamen Indikatorebene angeordnet, zu der die Rotationsachse senkrecht ausgerichtet ist, sodass mehrere Indikatorelemente in einer einzigen Ebene angeordnet sind; und/oder
3. (c) ist die Befestigungsnut negativ schwalbenschwanzförmig ausgebildet und jedes der Indikatorelemente weist einen korrespondierenden, positiv schwalbenschwanzförmigen Indikatorfuß auf, oder ist die Befestigungsnut negativ T-förmig ausgebildet und jedes der Indikatorelemente weist einen korrespondierenden, positiv T-förmigen Indikatorfuß auf.

The invention relates to an adjusting device for adjusting components that can be coupled to the adjusting device, in particular for adjusting a reticle device of a rifle scope, with an adjusting cap device with an adjusting cap which is rotatably mounted on a base part for mechanical actuation of the adjusting device by a rotary movement about an axis of rotation. A coupling part is designed to transmit a manipulated variable, which results from the movement of the adjusting cap, to a component that can be connected to the coupling part in order to adjust it. The adjusting cap has a circumference around the axis of rotation on a lateral surface on which a scale is applied, which interacts with a position mark on the side of the base part, in particular in order to be able to read the position of the adjusting cap relative to the base part, the adjusting cap device being in the The lateral surface of the adjusting cap has a fastening groove formed along the circumference, in which at least one adjustable indicator element is fixed, which rotates with the adjusting cap relative to the base part and marks a defined scale value of the scale. Furthermore is It is provided that each of the indicator elements can be arranged by sliding along the entire circumference of the fastening groove. According to the invention

1. (a) the fastening groove is aligned parallel to the axis of rotation; and or
2. (b) the mounting groove and each of the indicator elements are arranged in a common indicator plane to which the axis of rotation is perpendicular, so that a plurality of indicator elements are arranged in a single plane; and or
3. (c) the fastening groove is negatively dovetail-shaped and each of the indicator elements has a corresponding, positive dovetail-shaped indicator base, or is the fastening groove negatively T-shaped and each of the indicator elements has a corresponding, positive T-shaped indicator base.

The advantage of this is that an adjusting device is created with which a quick, safe and easily reproducible adjustment is guaranteed. It is therefore possible for one indicator element or several of the indicator elements to be individually definable in order to be able to operate an individual ballistic curve, specified by the user. The adjusting device remains compact. If possible, the indicator elements should be clearly noticeable to the user even in the dark, thus avoiding incorrect settings in the dark. Because this new functionality is completely implemented in the adjusting device, it can be used as a standard assembly in a variety of different rifle scopes, in particular also as a replacement or exchange component for other adjusting devices. Because each of the indicator elements can be arranged by sliding along the entire circumference of the fastening groove, maximum flexibility is enabled in determining the defined scale values.

According to a more detailed embodiment of the adjusting device, it is provided that at least one further indicator element is fixed in the fastening groove, which rotates with the adjusting cap relative to the base part and marks a defined scale value of the scale. This makes it possible to quickly switch between two or more marked positions of the adjusting device, for example if different ammunition or an optional silencer is used or if you want to switch back and forth between different firing distances or environmental parameters.

In a special embodiment, each of the indicator elements is designed to be removable from the fastening groove in a non-destructive manner. This means that the number of indicator elements can be freely chosen by the user, in particular by adding or removing them.

To the extent that the fastening groove and each of the indicator elements are arranged in an indicator plane (i.e. in particular a common plane) to which the axis of rotation is aligned perpendicularly, it is advantageous that several indicator elements can be arranged in a single plane and the adjusting device is compact. In particular, the adjusting device can be designed to be flat.

For a precise definition of the defined scale values, an optional design is available, according to which each of the indicator elements has an indicator tip. It is preferable that the indicator tips point in the direction of the base part, in particular parallel to the axis of rotation.

Furthermore, the design of the indicator elements can be pointer-like. As a result, the indicator elements are slim, which enables the use of numerous indicator elements or even closely spaced arrangements of two or more indicator elements.

According to the construction according to the invention, in which the fastening groove is either negatively dovetail-shaped and each of the indicator elements has a corresponding, positive dovetail-shaped indicator base, or the fastening groove is negatively T-shaped and each of the indicator elements has a corresponding, positive T-shaped indicator base, These geometries can provide precise guidance and the indicator elements are secured against loss. The indicator tip is preferably aligned parallel to the orientation of the indicator base. An embodiment is available in which the indicator tip is formed on a leg which is arranged at the free end of the indicator base protruding from the fastening groove.

Furthermore, a configuration is to be preferred according to which the fastening groove is arranged on the side of the scale facing away from the position mark. Here the indicator elements cannot obscure the view of the position mark and the area of the scale opposite.

A high degree of flexibility in use and a high level of operating comfort are achieved in an embodiment according to which each of the indicator elements can be clamped in a force-fitting manner in the fastening groove.

The same advantages arise if each of the indicator elements has a clamping means with which the respective indicator element can be released for displacement in the fastening groove and can be clamped in the fastening groove for fixing.

The clamping means can be a screw that is screwed into the respective indicator element. This makes the construction extremely simple. Optionally, the screw is a grub screw. When installed, this is almost concealed and does not interfere with the reading of the scale or otherwise hinder ease of use. The screw is preferably aligned perpendicular to the fastening groove. This means that it can be easily operated from outside the fastening groove and the indicator element does not tend to slip when screwed tight. For the same reasons, it is preferable that the screw is aligned perpendicular to the axis of rotation. In a special construction, the screw for fixing the respective indicator element can be screwed through this indicator element to such an extent that it comes into contact with a groove bottom of the fastening groove. This means that the screw and thus the indicator element can be clamped against the fastening groove. In particular, the screw can be screwed through a hole which extends through the end of the indicator base that projects out of the fastening groove.

In an optional embodiment, when the clamping device is released, a clearance fit with positive locking is formed between the fastening groove and the respective indicator element. The positive fit prevents the indicator element from falling off and the clearance fit allows the indicator element to be moved along the fastening groove.

Conversely, a design is to be preferred according to which a positive press fit is formed between the fastening groove and the respective indicator element when the clamping means is tightened. This results in a stable definition.

Optionally, it is possible for the indicator element to be elastically deformed within the fastening groove in the clamped state. This allows stable tension to be achieved.

In a further development of the adjusting device it is provided that each of the indicator elements has a visual identifier, preferably an individual letter or an individual number. For example, an individual color is also possible. This allows the user to better assign the different defined scale values.

According to an optional embodiment, the adjusting cap has a carrier element and a cap, wherein the cap is detachably fixed on the carrier element and the fastening groove is formed between the carrier element and the cap. This allows the indicator elements to be inserted into or removed from the groove after the cap has been loosened.

The cap preferably has a handle structure, in particular on its circumference. In addition, it can be provided that the carrier element and the cap each form a section of the lateral surface, these sections preferably being annular. Optionally, the cap is releasably screwed onto the support element. This allows the user to remove and reattach the cap repeatedly and reproducibly. It proves to be particularly advantageous if the cap is held non-positively on the carrier element by the respective indicator element when the clamping means is tightened. This means that the cap is secured, either additionally or exclusively.

In a more detailed embodiment, the coupling part is designed to transmit the movement of the adjusting cap device electronically and/or mechanically to components that can be connected to the coupling part in order to adjust them.

In particular, the coupling part can be an adjusting bolt coupled to the adjusting cap device in such a way that a rotation of the adjusting cap about the axis of rotation relative to the base part causes a longitudinal displacement of the adjusting bolt along the axis of rotation. This allows you, for example, to push or pull an adjacent actuator to actuate it.

The invention also relates to a riflescope with a tube housing through which an optical path runs, along which an eyepiece system, a reticle and an objective system are arranged, and with an adjusting device as described above and below, the coupling part being connected to the reticle in this way is coupled that the movement of the adjusting cap is coupled to the reticle for the purpose of adjusting it. The reticle can therefore be positioned precisely and quickly in the optical path according to the indicator elements. Preferably, the entire adjusting device is designed to be interchangeable. This allows you to quickly switch between different ammunition or silencers. The advantages of the rifle scope also correspond to the respective optional configurations of the adjusting device.

Optionally, the riflescope has a reversing system that is arranged along the optical path between the eyepiece system and the objective system, the optical path having a first image plane between the objective system and the reversing system and a second image plane between the eyepiece system and the reversing system. This provides an erect image for the user. This is in particular because the reversal system displays an upside down image in the first image plane upright in the second image plane.

The reticle should be arranged in one of the first and second image planes. This makes it clearly visible.

Furthermore, it is preferable that the riflescope has a variable magnification. This allows you to target targets at different distances. The variable magnification can be achieved by means of at least one lens that can be adjusted along the optical path. Preferably, the variable magnification is effected by means of at least two lenses that can be adjusted along the optical path, with a correlation, preferably a mechanical correlation, existing between the movement of the first and second adjustable lenses.

The systems, i.e. the eyepiece system, objective system and reversing system, are to be understood as lens arrangements, in particular with convex lenses, concave lenses, diffusing lenses, concentrating lenses, achromats and/or the like.

The invention also relates to a firearm with such a telescopic sight. The advantages of the firearm correspond to the respective optional designs of the adjusting device and the rifle scope.

In Fig. 1 You can see an adjusting device 1 in an exploded view. This adjusting device is shown in Fig. 2 an indicator element 24 is shown enlarged. Finally, the adjusting device is after Fig. 1 reassembled in a side view with a partial section in the Fig. 3 shown. The Fig. 1 , 2 and 3 are therefore described together, with the same reference numbers referring to the same components. The adjusting device 1 is in particular for adjusting components that can be coupled to the adjusting device 1, in particular for Adjusting a reticle device (reticle for short) of a rifle scope 50 (see Fig. 4 ) intended.

How to especially in the Fig. 1 and 3 recognizes, the adjusting cap device 10 has an adjusting cap 11, which is rotatably mounted on a base part 40 for mechanical actuation of the adjusting device 1 by a rotary movement about an axis of rotation A, at least indirectly. A coupling part 42, which is in particular according to Fig. 3 is designed as an adjusting bolt 43, is intended to transmit a manipulated variable, which results from the rotational movement of the adjusting cap 11, to a component that can be connected to the coupling part 42 for the purpose of its adjustment. The coupling part 42 is in particular an adjusting bolt 43 coupled to the adjusting cap device 10 in such a way that a rotation of the adjusting cap 11 about the axis of rotation A relative to the base part 40 causes a longitudinal displacement of the adjusting bolt 43 along the axis of rotation A.

The adjusting cap 11 has a lateral surface 12 on a circumference around the axis of rotation A, in particular in order to grip and rotate the adjusting cap 11 here. A scale 13 is applied to the lateral surface 12 and interacts with a position mark 41 on the side of the base part 40. The user can therefore determine the set value based on the scale value to which the position mark 41 points.

Furthermore, the adjusting cap device 10 has a fastening groove 20 formed along the circumference in the lateral surface 12 of the adjusting cap 11, which is arranged on the side of the scale 13 facing away from the position mark 41. At least one adjustable indicator element 21, here in particular four indicator elements 21, 22, 23, 24, which rotate with the adjusting cap 11 relative to the base part 40 and each have a defined scale value P1, P2, P3, P4 of the scale 13, is fixed in this fastening groove 20 to mark. The fastening groove 20 and each of the indicator elements 21, 22, 23, 24 are arranged in an indicator plane E, to which the axis of rotation A is aligned perpendicularly.

Each of the indicator elements 21, 22, 23, 24 can be arranged by sliding along the entire circumference of the fastening groove 20 and can be individually and individually determined, for example in order to be able to operate an individual ballistic curve, specified by the user. Each of the indicator elements 21, 22, 23, 24 can also be removed non-destructively from the fastening groove 20, so that the number of indicator elements 21, 22, 23, 24 can be freely selected by the user, in particular by adding or removing them.

For this purpose, the fastening groove 20 is negatively T-shaped and each of the indicator elements 21, 22, 23, 24 has a corresponding, positive T-shaped indicator base 26, which is in the fastening groove 20 is included. Instead of a positive fit using a T-shape, a positive fit using a dovetail shape could also be considered. Each of the indicator elements 21, 22, 23, 24 can be clamped in the fastening groove 20 in a non-positive manner.

How to zoom in on the Fig. 2 can recognize, the indicator element 24 shown there has an indicator tip 25. The indicator tip 22 is aligned parallel to the orientation of the indicator base 26. For this purpose, the indicator tip 25 is formed on a leg 32, which is at the free end of the fastening groove 20 (cf. Fig. 3 ) projecting indicator base 26 is arranged. The indicator tips 25 of the indicator elements 21, 22, 23, 24 each point in the direction of the base part 40, in particular parallel to the axis of rotation A (cf. Fig. 1 and 3 ). In addition, the indicator element 24 has Fig. 2 via a visual identifier 30, which in the present case is an individual number, namely the number “4”. With the exception of the individual identifier 30, the indicator element 24 shown is identical in construction to the other indicator elements 21, 22, 23 Fig. 1 and 3 .

Each of the indicator elements 21, 22, 23, 24 has a clamping means 27 with which the respective indicator element 21, 22, 23, 24 can be released for displacement in the fastening groove 20 and can be clamped in the fastening groove 20 for fixing. The clamping means 27 is a screw 28, in particular a grub screw, which is screwed into the respective indicator element 21, 22, 23, 24. These screws 28 are each aligned perpendicular to the fastening groove 20 and to the axis of rotation A. To fix the respective indicator element 21, 22, 23, 24, the screws 28 can be screwed through the respective indicator element 21, 22, 23, 24 to such an extent that they come into contact with a groove base 29 of the fastening groove 20. For this purpose, the respective indicator element 21, 22, 23, 24 has a hole 31 which extends through the end of the indicator base 26 protruding from the fastening groove 20. The groove bottom 29 is cylindrical and flat.

When the clamping device 27 is released, there is a clearance fit with positive connection between the fastening groove 20 and the respective indicator element 21, 22, 23, 24. When the clamping means 27 is tightened, this changes to a certain extent to a form-fitting press fit between the fastening groove 20 and the respective indicator element 21, 22, 23, 24, in particular due to the clamping means 27 to be added to the respective indicator element 21, 22, 23, 24. In particular, the indicator element 21 , 22, 23, 24 are elastically deformed in the clamped state within the fastening groove 20, at least slightly.

It can be seen that the adjusting cap 11 has a multi-part support element 14 and a cap 15, the cap 15 having an internal thread 18 being releasably mounted on an external thread 19 of the Carrier element 14 is screwed tight. Additional securing of the cap 15 on the carrier element 14 is achieved by a screw 17. In addition, the cap 15 is held non-positively on the carrier element 14 by the respective indicator element 21, 22, 23, 24 when the clamping means 27 is tightened. Both the carrier element 14 and the cap 15 each form an annular section of the lateral surface 12. The cap 15 here has a handle structure 16.

The fastening groove 20 is formed between the carrier element 14 and the cap 15. By removing the cap 15, indicator elements 21, 22, 23, 24 can be removed or inserted, for example by unhooking or hanging on the carrier element 14.

The Fig. 4 and 5 show a rifle scope 50 with the adjusting device 1 according to the Fig. 1 , once from a perspective view and once as a longitudinal section. The rifle scope 50 has a tube housing 51 through which an optical path P runs. An eyepiece system 52, a reversing system 55, a reticle 54 and an objective system 53 are arranged in the tube housing 51 along this optical path P. The reversing system 55 is arranged along the optical path P between the eyepiece system 52 and the objective system 53, the optical path P having a first image plane BE1 between the objective system 53 and the reversing system 55 and a second image plane BE2 between the eyepiece system 53 and the reversing system 55 . The image planes BE1, BE2 are exclusively the result of the optical rays that pass through the optical path P. An optical element can optionally be arranged in the image planes BE1, BE2. Alternatively, however, it is also possible for the image planes BE1, BE2 to be positioned in the area of a cavity. The reversal system 55 represents an upside down image in the first image plane BE1 and upright in the second image plane BE2.

The telescope 50 has a variable magnification, which is achieved by means of two lenses 58, 59 that can be adjusted along the optical path P, with a mechanical correlation existing between the movement of the first and second adjustable lenses 58, 59. These two adjustable lenses 58, 59 are part of the reversing system 55. With the help of a magnifying ring 57 on the side of the tubular housing 51, on which the eyepiece system 52 is also arranged and through which the optical path P runs, the two adjustable lenses 58 , 59 change their position along the optical path P and thus adjust the magnification. This adjustment of the two adjustable lenses 58, 59 is effected by means of a cam mechanism of the reversing system 55.

The adjusting device 1 sits on a stop surface on the outside of the tubular housing 51 and is presently intended for distance adjustment, as a so-called height tower. Alternatively or additionally, the different lateral adjusting device can also be used for Crosswind, namely the side adjustment tower 56, by an adjusting device according to the Fig. 1 to 3 be equipped. Here, of course, a different scale would have to be provided on the lateral surface 12.

The coupling part 42 is coupled to the reticle 54 in such a way that the movement of the adjusting cap 11 for the purpose of adjusting the reticle 54 is coupled to it. For this purpose, the entire reversing system 55, which sits in an inner tube 60, is pivoted within the tube housing 51.

In the present case, the reticle 54 sits in the first image plane BE1. However, in deviation from this, the reticle 54 can also be arranged in the second image plane BE2. The reticle 54 may be a graphical representation and/or an electronic display.
