Description

The invention relates to an adjusting device for the adjustment of a telescopic sight according to the preamble of claim 1 and a telescopic sight, which has such an adjusting device according to claim 17.

Especially for hunting purposes but also for military use riflescopes have been further developed in recent decades. They typically consist of a riflescope housing of generally cylindrical shape having at each end an eyepiece or objective optic tube and, in between, a reversing arrangement for image formation. In this middle, narrower tube area is also a reticle, ie a target. To adjust it is generally a radially projecting actuator mechanism on the central tube region, for example, a screw according to DE 32 08 814 A1 or DE 37 37 856 A1 ,

Important is an adjustment option such that breakpoint and meeting point coincide. If the target distances are highly variable, parallax-related deviations of the image plane of the target from the reticle level can be extremely disturbing. This can be compensated with a parallax compensation. Conventionally, it is done by axial displacement of the objective lens. In addition, manufacturing tolerances, firing distance and crosswind can lead to target mark deviations that need to be corrected by means of an adjustment. These adjusting devices, in particular adjusting towers, are usually arranged laterally on the sighting telescope housing.

To adjust the reticle at least two adjusting devices are arranged in particular on the outside of the scope frame at circumferential intervals of 90 degrees, each having an adjusting device in the form of a locking ring or an adjusting cap. Here, a first and second Verstellturm the height or lateral adjustment.

For example, in DE 297 207 37 U1 a riflescope with a tubular housing described which has tube sockets for an eyepiece and a lens assembly. In this case, an optical reversing arrangement and a reticle associated therewith are present in a central tube, which is fixedly mounted on the double tube in a socket. A threaded drive is guided in a tubular body slot and presses against the reverse arrangement against a spring force from the front. It is movable back and forth in its longitudinal direction by turning the adjusting device.

Conventionally, such, about a total of about 360 degrees rotatable adjustment has a fine detent such division that it moves during rotation (click adjustment) one step further, which changes the impact hit position to 100 m, for example, by 10 mm. On the outer circumference of the adjusting device, a scale is applied, on which one can read the correction made. For example, depending on the division, each click is marked with a white line, and every tenth click is indicated by a number. The problem with the known embodiments in the prior art, however, is that the reticle adjusted unintentionally when a location of the shooter. An adjustment can be done, for example, by rubbing garments on one of the adjusting elements. The documents CN201706979 and EP2472214 are other relevant prior art documents.

It is therefore an object of the invention to develop an adjusting device and a telescopic sight equipped therewith, which is designed to be as compact as possible and still easily operable but at the same time protected against accidental adjustment. Conveniently, the Verstellurm should be simple and inexpensive to manufacture, as well as robust and durable in use, and eliminate the other disadvantages of the prior art.

Main features of the invention are specified in the characterizing part of claim 1. The invention relates to an adjusting device for the adjustment of a telescopic sight, with a manually operable adjusting element which is mounted rotatably about an axis of rotation relative to a base. Between the base and the adjusting element, a latching device is arranged, which has latching recesses distributed over the circumference around the axis of rotation, wherein a first latching element of the latching device faces in relation to the rotational position of the adjusting element relative to the base of one of the latching depressions. According to the invention the adjusting device has a locking device which has a manually operable locking element which is manually movable from a release position to a locking position, wherein the locking element is coupled via an adjusting drive with the first locking element, wherein the first locking element in the locking position by means of the actuating drive mechanically determined in the respective opposite locking recess and a rotation of the adjusting element is locked relative to the base.

Thus, a plurality of locking positions for the adjustment is provided depending on the number of locking recesses, so that this does not move unintentionally. The exploitation of distributed over the circumference detent recesses allows it to use this in a double function, namely for adjusting the adjustment with tactile detent steps and the detection of the adjustment with the first locking element, which also engages in one of the locking recesses. As a result, the adjusting device is compact and at the same time easy to design. In the release position, the first latching element should not be detected mechanically by the actuating drive in the respectively opposite latching recess, so that then a rotation of the adjustment element relative to the base is released.

According to a special embodiment, the latching depressions are formed in a latching ring of the latching device. This allows the locking recesses easily and inexpensively produce. In addition, a function suitable material can be selected for the locking ring, which differs from the other components.

In a variant of the adjusting device, the locking ring is arranged co-rotating on the rotatable adjusting element. Thus, the number of co-rotating components is kept low and the assembly is particularly simple.

Alternatively, the locking ring can also be formed integrally with the adjusting element. As a result, the number of components is low.

In an optional embodiment, the locking recesses are designed to be open in the direction of the axis of rotation. This allows a flat design of the adjusting element, because the locking element can be mounted between the rotation axis and the locking ring. Preferably, the adjusting element is a hollow adjusting knob. Such is suitable for receiving the latching device and the locking device in the cavity and thereby protect. So it is possible, for example, that the locking ring sits on the inside of the hollow adjustment knob.

According to a further embodiment variant, the locking element is mounted independently of the adjusting element relative to the base between the release position and the blocking position about the rotational axis. Thus, a common axis of rotation can be used, whereby the design is compact. In addition, the operation is conveniently possible.

A particularly compact design succeeds when the locking member has a disk body, which is arranged between the base and the adjusting element, and which is mounted independently of the adjusting relative to the base between the release position and the locking position about the rotation axis.

For comfortable operation, an optional design is available, in which a gripping surface is arranged on the disk body, which protrudes radially relative to the axis of rotation over the adjusting element. At this supernatant, the gripping surface can also form an angle and extend along the axis of rotation to next to the adjustment, but preferably at most over an angle about the axis of rotation of 90 degrees, more preferably of at most 60 degrees and more preferably of at most 45 degrees. He can be well used.

An intuitively simple operation succeeds when between the release position and the blocking position, a rotation angle about the rotation axis of substantially 90 degrees.

Optionally, it is possible for the first latching element to be acted upon by a spring force in the direction of the respectively opposite latching recess. Thus, the first locking element in the release position and the tactile tactile screening at an adjustment of the adjustment is used. This increases the functionality of the adjusting device with few components. Therefore, this embodiment should preferably be selected when the first latching element is the only latching element of the latching device.

In accordance with a further design option, at least one second latching element of the latching device is arranged relative to the rotational position of the adjusting element relative to the base of one of the latching recesses, wherein the at least one second latching element is acted upon by a spring force in the direction of the respectively opposite latching recess. Thus, the second locking element of the tactile tactile screening is used in an adjustment of the adjustment. It is then not necessary to apply the first detent element with a spring force in the direction of the respective opposing detent recess. Here, the first and second locking element share the locking recesses, which are therefore provided only once.

Optionally, the second locking element can not be coupled via the adjusting drive with the locking element, or in a second option, the locking element can be coupled via the adjusting drive with the at least one second locking element, wherein the at least one second locking element in the locking position by means of the actuating drive mechanically in the each opposite locking recess found and a rotation of the adjustment is locked relative to the base. In the first option, the second locking element is thus used only for tactile screening when adjusting the adjustment and not for detection. In the second option, however, the second locking element has a double function, namely on the one hand with respect to the tactile screening when adjusting the adjustment and the other to its locking.

According to a particular embodiment, at least a third latching element of the latching device is in dependence on the rotational position of the adjusting relative to the base of one of the locking recesses, wherein the locking element is coupled via the adjusting drive with the at least one third latching element, wherein the at least one third Detent element in the locked position by means of the actuator mechanically detected in the respective opposite locking recess and a rotation of the adjusting element is locked relative to the base. By at least the first and third locking elements are used to locks the rotation, the recordable torque is high and a violent further rotation of the adjusting element in the blocking position is avoided.

In a special embodiment, the first latching element and / or the at least one third latching element are freely slidably mounted. In other words, these locking elements are not acted upon by a spring force. They do not serve the tactile screening when turning the adjustment, but only to its locking.

The design of the locking elements and the detent recesses should generally be chosen so that the locking elements are pushed out of the detent recesses upon rotation of the adjusting element about the axis of rotation.

A good compromise between a compact design and a lock that can accommodate high torques, creates an embodiment in which the adjusting device is provided with a maximum of two third locking elements and preferably exactly one third locking element. Thus, two or three locking elements are provided which are locked in the locking position, namely the first locking element and one or two third locking elements. Optionally comes a second locking element that is either spring-loaded or is also locked.

A simple and compact construction succeeds when the latching elements comprising the first latching element and, if provided, the at least one second latching element and, if provided, the at least one third latching element are each mounted linearly displaceable. In this case, the latching elements can be designed like a slide. In other words, the locking elements are then locking slide.

Particularly preferably, the locking depressions are all on a (single) orbit around the axis of rotation.

In a special design, which leads to a flat construction of the adjusting device, it is provided that the latching elements comprising the first latching element and, if provided the at least one second latching element and, if provided, the at least one third latching element are each mounted so as to be linearly displaceable towards and away from the axis of rotation.

A simple design and a handy assembly succeed in an optional design, according to which the locking elements, comprising the first locking element and provided the at least one second locking element and provided the at least one third locking element, each rotatably mounted relative to the axis of rotation, this particular on the Base.

In an optional embodiment, the latching elements, comprising the first latching element and, if provided, the at least one second latching element and, if provided, the at least one third latching element, are uniformly distributed over the circumference about the axis of rotation. Thus, an even distribution of the introduced with the locking elements forces is achieved and also ensures that high torques can be absorbed in the locked position. This results, for example, in a three-point or four-point lock.

Particularly simple and compact is a closer embodiment in which the actuator has a control cam, which kinematically couples the locking element with the first locking element and provided with the at least one third locking element. Optionally, in addition, a second latching element can be kinematically coupled to the control cam. In this way, a cam gear can be formed.

In this case, there is the option that the control cam is arranged co-rotating on the locking element and corresponds in each case with a sliding surface of the first locking element and, if provided, of the at least one third locking element. Optionally, in addition, a second locking element having a sliding surface over which it is kinematically coupled to the control cam. The sliding surfaces may each be integrally formed on the latching elements.

According to a special detailed solution is with the control cam exclusively a compressive force in the direction of the respective opposite locking recess on the first locking element and if provided the at least one third locking element exercisable. Thus, the control cam is decoupled in the pulling direction of the first locking element and / or the at least one third locking element. Optionally, this can also be carried out between the control cam and a second latching element.

Such an adjusting device preferably has an adjusting bolt, wherein with the adjusting element, the position of the adjusting bolt is adjustable, which is movably mounted along the axis of rotation. With an adjusting bolt, for example, a reticle can be adjusted by the adjusting bolt exerts pressure on a pivotally mounted in the rifle scope housing reversing system and this pivots.

The invention also relates to a telescopic sight with an adjusting device as described above and below. Thus, a scope is provided with a comfortable and compact adjustment. In particular, the adjusting device with the base should be arranged on a riflescope housing of the riflescope. In one option, the base is fixed to the scope frame. This allows the adjustment easily and independently mount or replace. In another option, the base is formed by a scope frame of the scope. This means fewer components and coupling points are necessary.

In a particular embodiment, the adjusting device for adjusting a reticle is coupled to the reticle. Thus, the adjustment and thus the reticle can be determined or locked by means of the locking device. Optionally, one of the locking elements can be used to provide tactile detent steps, so that a shooter when adjusting does not have to watch a scale, but can fixate on the target. The desired position is then achieved by counting the locking steps.

Fig. 1 shows a perspective view with 45 ° -partial section of an adjusting device 1. The same adjusting device 1 is in Fig. 2 shown in a perspective view with 225 ° partial section. Fig. 3 again shows the same adjustment 1, but in a perspective view of an exploded view. From the views of Fig. 4 and 5 go from a vertical view on an open adjusting device 1 according to the Fig. 1 . 2 and 3 in particular a release position S1 and a blocking position D2 of a locking device 40.

In the Fig. 1 . 2 . 3 . 4 and 5 one recognizes in each case an adjusting device 1 for the adjustment of a telescopic sight. This has a manually operable adjusting element 20 which is mounted rotatably about a rotation axis A relative to a base 10. Between the base 10 and the adjusting element 20, a latching device 30 is arranged, which has locking recesses 31 distributed over the circumference about the axis of rotation A. A first latching element 32 (in Fig. 1 not visible), a second locking element 33 (in Fig. 1 not visible) and a third locking element 34 (in Fig. 1 . 2 and 3 not visible) of the latching device 30 is in each case depending on the rotational position of the adjusting element 20 relative to the base 10 of the latching recesses 31 opposite. The second locking element 33 is provided with a spring force F (not in the Fig. 2 and 3 plotted), acted upon in the direction of the respective opposite locking recess 31. In addition, the adjusting device 1 has a locking device 40, which has a manually operable locking element 41, the manually from a release position S1 (see Fig. 4 ) in a blocking position S2 (see Fig. 5 ) is movable. In this case, the locking element 41 is coupled via an actuating drive 50 with the first latching element 32, the second latching element 33 and the third latching element 34. The first latching element 32, the second latching element 33 and the third latching element 34 are in the blocking position S2 (see Fig. 5 ) each detected by means of the actuator 50 mechanically in the respective opposite locking recess 31 and a rotation of the adjusting element 20 is relative to the base 10 is locked.

This basic construct is one embodiment of the invention, refined by the optional detailed solutions described below. One recognizes in the Fig. 1 . 2 . 3 . 4 and 5 in each case that the latching recesses 31 are formed in a latching ring 35 of the latching device 30. In this case, the latching recesses 31 are designed to be open in the direction of the axis of rotation A.

The locking ring 35 is co-rotating with the rotatable adjusting element 20. The adjusting element 20 is a hollow adjusting knob. In this sits the locking ring 35 on the inside. This position is achieved by an ice corners of the locking ring 35 in the hollow adjustment knob.

The locking element 41 is mounted independently of the adjusting element 20 so as to be rotatable relative to the base 10 between the release position S1 and the blocking position S2 about the axis of rotation A. In this case, the locking element 41 has a disk body 42 which is arranged between the base 10 and the adjusting element 20 and which is mounted independently of the adjusting element 20 relative to the base 10 between the release position S1 and the blocking position S2 about the rotation axis A. In particular, between the release position S1 (see Fig. 4 ) and the blocking position S2 (see Fig. 5 ) a rotation angle about the rotation axis of 90 degrees. The angle of rotation is limited by stops 44, 45. In particular, the first stop 44 beats in the release position S1 (see Fig. 4 ) on a stop element 11 (see Fig. 3 . 4 and 5 ) at. The second stop 45 strikes in the blocking position S2 (see Fig. 5 ) on the same stop element 11 (see Fig. 3 . 4 and 5 ) at.

Furthermore, it can be seen that a gripping surface 43, which projects radially beyond the adjusting element 20 relative to the axis of rotation A, is arranged on the disk body 42. At this projecting projection, the gripping surface 43 forms an angle with which it extends along the axis of rotation A to adjacent to the adjusting element 20. However, the height of the gripping surface 43 along the axis of rotation A is less than 50% of the height of the adjusting element 20 (cf. Fig. 1 ). In addition, the gripping surface 43 extends circumferentially about the adjusting element by less than 90 degrees, less than 60 degrees and in particular less than 45 degrees (see in particular Fig. 4 and 5 ).

The first latching element 32, the second latching element 33 and the third latching element 34 are each mounted on the base 10 and thus do not rotate about the axis of rotation A. As can be seen, the first latching element 32, the second latching element 33 and the third latching element 34 respectively mounted linearly displaceable, in particular perpendicular to the axis of rotation A and toward and away from the axis of rotation A. Here, the first locking element 32 and the third locking element 34 are freely slidably mounted and not not acted upon by a spring force (see, in particular Fig. 4 and 5 ). The locking elements 32, 33, 34 are thus formed like a slide. In other words, the locking elements 32, 33, 34 then locking slide.

Upon rotation of the adjusting element 20 about the axis of rotation A, these locking elements 32, 34 then from the locking recesses 31 from the locking position pushed out, especially once. The second locking element 33, however, jumps due to the spring 38 and the spring force F in each passing latching recess 31st

Especially in the Fig. 4 and 5 can be seen, the star-shaped alignment of the locking elements 32, 33, 34 about the rotation axis A. In particular, the first locking element 32, the second locking element 33 and the third locking element 34 are uniformly distributed over the circumference about the axis of rotation A.

For adjusting or locking the latching elements 32, 33, 34, the actuating drive 50 has a control cam 51, which kinematically couples the locking element 41 with the first latching element 32 and the third latching element 34. Depending on a survey of the control cam 51 presses one of the locking elements 32, 33, 34 in the blocking position S2 in a recess 31 (see Fig. 5 ).

The cam 41 is co-rotating and integrally formed on the locking element 41, in particular on the disk body 42 and corresponds with a respective sliding surface 36 of the locking element 32, 33, 34th

With the cam 41 is exclusively a compressive force in the direction of the respective opposite locking recess 31 on the locking elements 32, 33, 34 exercisable. That is, in the pulling direction, the control cam 41 is decoupled from the locking elements 32, 33, 34th

With the adjusting element 20, the position of an adjusting pin 21 is adjustable by rotation about the axis of rotation A, which is mounted movably along the axis of rotation A. Preferably, the adjusting bolt 21 is screwed with a thread into the base 10 for this purpose.

Fig. 6 shows a perspective view of a riflescope 100 with a plurality of adjusting devices 1 of the type according to Fig. 1 . 2 . 3 . 4 and 5 , In particular, two adjusting devices 1 are mounted offset by a rotation angle of 90 degrees to each other at a central part of a riflescope housing 101. For this purpose, the base 10 is in each case in contact with the scope housing 101. Alternatively, however, the base 10 may also be formed directly from the scope housing 101.

An objective 102 and an eyepiece 103 are located in the tubular telescopic housing 101 at the end. In the central part between the objective 102 and the eyepiece 103, a pivoting reversing system is arranged in the scope housing 101. By Pivoting the inversion system allows the position of a reticle to be adjusted relative to a target position, in particular to set a firing distance or to compensate for crosswinds. This pivoting is done with the two adjusting devices 1. You can in Fig. 6 Also clearly recognize that the gripping surface 43 on the disk body 42 of the locking member 41 does not protrude so far from the scope housing 101 as that the adjusting element 20th

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

Alternatively or in addition to the embodiment shown, the first detent element 32 could also be acted upon by a spring force F in the direction of the respective opposing detent recess 31.

In general, there is the option that only a first locking element 32 is provided or a plurality of locking elements from the group first, second and third locking element 32, 33, 34, but preferably a maximum of five.

A modification may also consist in that the sprung second latching element 33 is not coupled via the actuating drive 50 with the locking element 41.

All of the claims, the description and the drawings resulting features and advantages, including design details, spatial arrangements and method steps may be essential to the invention both in itself and in various combinations. <B> LIST OF REFERENCES </ b> 1 adjustment 42 washer body 43 grip 10 Base 44 first stop (release position) 11 stop element 45 second stop (blocking position) 20 adjustment 50 actuator 21 adjusting pin 51 cam 30 locking device 100 Scope 31 locking recesses 101 Riflescope 32 first locking element 102 lens 33 second locking element 103 eyepiece 34 third catch element 35 locking ring A axis of rotation 36 Sliding surface (first locking element) F spring force 38 feather S1 release position S2 blocking position 40 locking 41 locking
