Abstract

Brief description: A height - reticle adjustment has the main task of being able to adjust the rifle scope to different target distances, so that, despite gravity-related bullet drop, the target image corresponds to the actual point of impact of the bullet. Finding the right setting for the existing target distance is mostly complicated with the state of the art in mechanical systems and overwhelms most shooters, since for technical reasons there are usually no direct distance information, but numbers without reference to the distance. The following reasons have usually prevented this :- Lack of space on the reticle adjustment turret- Several turns of the adjustment are necessary to be able to adjust finely enough, which previously made it difficult to assign the turn position to precise distance information.- Different calibers or bullet weights, powder quantities, weapon types need different scaling of the distance information to really to allow precise settings.Solution: A reticle adjustment turret which indicates the position of rotation based on different heights of an LED, which in turn illuminates the correct distance information on a custom-made sticker from the inside.

Description

A projectile fired by a weapon (ball, projectile) falls further and faster during the flight due to the existing gravity. Therefore, a telescopic sight must have a reticle adjustment, i.e. a height adjustment of the reticle (e.g. crosshairs), so that countermeasures can be taken at different distances. The problem with this, however, is that the majority of all shooters have problems setting this correctly at a certain distance. Because usually the information on the reticle adjustment turret does not correspond to an exact distance in meters or yards, but numbers are usually shown there, which depending on the make also have a completely different meaning, depending on the country have a different unit, depending on the fineness of the click grid have a different subdivision or gradation and even the direction of rotation of the adjustment turret is different depending on the make. In addition, there is the fact that a click results in a different change in the height of the hit location, depending on the distance from the target. All these complicated connections make it quite difficult for the shooter to find the exact setting.

Hunters usually circumvent the problem by having the gunsmith zero in the weapon to the most favorable zeroing distance (GEE). i.e. The gunsmith adjusts the telescopic sight by means of test shooting (zeroing in) in such a way that the projectile approximately hits the ammunition used in a certain range, usually in a range of plus or minus 4 cm. For the hunter, however, this means that he is limited to this range of distance to the game, e.g. 50 to 120 meters, his target should not be outside of this range. Furthermore, he should not change his type of ammunition, otherwise a new, expensive zeroing is necessary. Ultimately, this method is very imprecise because it is inherently designed for a range of 8 cm and there is also the ammunition spread. Because the gunsmith only adjusts the telescopic sight, but does not look for the ammunition that best suits the weapon. That can cause at least as much inaccuracy.

Sport shooters usually circumvent the problem of setting the scope by having an experienced shooter help you set it to a certain distance and then never changing the setting again, except at a different target distance, then remembering or writing down how many clicks the height adjustment needs to be adjusted from one distance to the other distance. However, this is very inaccurate, since the setting always has to be corrected depending on the prevailing conditions (light conditions, temperature, air pressure, etc.) and is also very error-prone. Every adjustment must be memorized exactly. In competition stress, this method very often leads to failure.

In the military, accurate hitting of targets at a wide range of distances, including very distant ones, is extremely important. Therefore, the snipers must learn how to set the scope at different distances in different conditions. Until now there was only ONE really safe way to do this. They use test shots to check how many clicks of height adjustment are necessary at which distance in order to hit the target exactly and write down all this data. This method is very accurate because it is based on actual conditions. So this rifle hits right there with that exact ammunition and under those exact conditions.

The problem with this method, just like with competitive shooters, is the excitement and stress when things "get serious". In action, in wartime, it's easy to get the wrong line when reading the data or miscount the clicks. Therefore, a compromise is usually made and scopes are used that have a coarser click adjustment, eg 0.1 mil/click. This means you have to count about three times fewer clicks than with a 1/8 Moa adjustment. However, this also has the disadvantage that the point of impact shift is three times larger per click. For example, at 100 meters there is a deviation of one centimeter per click instead of around three millimeters. At 1000 meters that's 10 centimeters per click. So it's not that finely adjustable. Overall, this method of converting, reading and counting clicks is also much slower than reading and setting the meter or yardage directly. In addition, you have to know exactly what distance the scope was last set to, so that you know the starting point of the calculation, otherwise the result will of course not be correct. Since one quickly forgets the distance at which the telescopic sight was last set, numerous systems have been invented to alleviate this problem, such as adjustment turrets that can be “zeroed”, i.e. the turret can be unscrewed and put back on so that the zero is on can be read from a marking. But then you still don't know in what number of revolutions the zero can be read. For this purpose, systems were invented to bring about a mechanical stop of the rotation, for example at the setting corresponding to 100 meters. In this way, the shooter can turn back to the Stop and he knows, for example, 100 meters are now set. However, if you correct a setting slightly or choose a different distance and expect this again the next time you shoot, it could be that the setting turret is twisted a bit when the gun is transported and the setting is no longer correct. To prevent this from happening, numerous different systems were invented that lock the tower against unwanted twisting.

All these problems would be solved if there was a reticle adjustment or a reticle adjustment tower with correct and very precise distance marking.

1. 1. Jede unterschiedliche Kombination aus Gewehr und Munition hat einen anderen Geschossabfall, also müsste die Beschriftung (genauer die Abstände der Meter-, Yardangaben) auf dem Verstellturm immer unterschiedlich sein.
2. 2. Um eine präzise Einstellung des Zielfernrohres zu ermöglichen bedarf es einer sehr feinen Klickverstellung. Das heißt, dass ein Klick nur wenig Höhenänderung der Trefferlage bewirkt. Das bedeutet aber, um den ganzen Verstellbereich eines Zielfernrohres ausnutzen zu können, muss sich der Turm einige Umdrehungen verstellen lassen. Meist sind zwischen sechs und zehn Umdrehungen nötig.

Dies wiederum bedeutet, dass eine Beschriftung des Absehenverstellturmes mit korrekten Meter- oder Yardzahlen bisher nicht gut möglich war, da bei beispielsweise 8 möglichen Umdrehungen des Absehenverstellturmes, auch 8 unterschiedliche Entfernungsangaben auf der gleichen Stelle angebracht sein müssten. Um dem zu entgehen müsste der Absehenverstellturm nur eine Umdrehung Verstellbereich haben, was wiederum eine extrem grobe Klickverstellung bedeuten würde und gleichzeitig nur Platz bietet für eine extrem grobe Entfernungsanzeige. Das macht ein präzises Einstellen unmöglich.However, this has not worked well so far for two reasons:

1. 1. Every different combination of rifle and ammunition has a different bullet drop, so the labeling (more precisely the distances between meters and yards) on the adjustment turret should always be different.
2. 2. In order to enable a precise adjustment of the rifle scope, a very fine click adjustment is required. This means that one click causes only a small change in the height of the hit position. However, this means that in order to be able to use the entire adjustment range of a telescopic sight, the turret must be able to be adjusted a few turns. Usually between six and ten turns are necessary.

This in turn means that labeling the reticle adjustment turret with correct meter or yard numbers has not been possible up to now, since, for example, 8 possible revolutions of the reticle adjustment turret would also require 8 different distance information to be displayed in the same place. To avoid this, the reticle adjustment turret would only have to have one turn of adjustment range, which in turn would mean an extremely coarse click adjustment and at the same time only offers space for an extremely coarse distance display. This makes precise adjustment impossible.

The state of the art:

1. 1. Riflescopes with fine click adjustment and several turns of adjustment range, but with numbers or markings instead of distance information as labels. Disadvantage: difficult to set up. This is the most common, widespread variant that almost every rifle scope manufacturer has in their range. Slightly modified variant with window, but same disadvantage: 20130312310 Geller [US]
2. 2. Riflescopes or systems for riflescopes with an adjustment range of only one turn, therefore with a rough click adjustment and rough distance specification. Disadvantage: Not precisely adjustable. Cannot be precisely labeled due to lack of space Examples: 3990155 AKIN JR ALFRED A [US] 201414462407 CRISPIN QUINT [US] 2016231085 (A1) PORTER JOHN [US] 3826012 (A) PACHMAYR F [US] 9057586 (B2) WAGNER THOMAS [DE] Theisinger Hermann 4285137 Jenny [US] 207318716 Guo Xinjian 20140268187 Daniel Nichols [US]
3. 3. Control button for a telescopic sight with a small window and an adjustment bolt that rotates the number ring a little further with the second turn of the adjustment button, so that it is possible to apply the labeling not only once but twice, so the turret has a different one for the second turn number label. Example: EP3489614A1 FEINBERG SETH ALAN [US]; JOYNER MATTHEW DAVID [US]; WHITE MATTHEW TRAVIS [US] Disadvantage: No meters or yards labeling is possible because the labeling with distance information is not linear and therefore may not match the windows. In addition, two turns are still not enough to enable a fine and thus precise click adjustment.
4. 4. Rifle scope with a reduction by a planetary gear in the reticle adjustment turret which allows a finer and thus more precise click adjustment with just one turn of the reticle adjustment turret. Disadvantage: Too little space, so only a very rough indication of the distance is possible, which in turn is imprecise. Example: 20170254620 Dasukevich [US]
5. 5. A telescopic sight or adjustment knob that moves up or down when you turn it and then releases the height markings underneath, similar to a micrometer screw, which allows you to read the number of turns you are in. Disadvantage: No distance scaling possible. Example: US6691447B1 OTTEMAN RODNEYH [US]
6. 6. A reticle adjustment turret driving a tape inscribed with distance information, wel ches is wound up in a larger box. This could allow fine click adjustment and fine distance indication. Disadvantage: Strange appearance. In addition, it is complicated to change the band if you want to shoot different ammunition and would therefore need a different scale on the band. 2010133874 (A1) BURNUP ALEXANDER [UK]
7. 7. A telescopic sight or reticle adjustment tower that offers several turns of adjustment range, so can offer a fine click adjustment. Disadvantage: Due to the design, since the labeling is on the inner rotatable part, the labeling area, and thus the writing, is very small and must therefore be enlarged with a sight glass with magnification in the window for legibility. This is technically very complex to produce and, on top of that, offers poorer readability, since, as is usual with a magnifying glass, the numbers appear different in size, blurred and distorted depending on the viewing angle. The invention is also not intended to display direct distance information, but simply a larger range of numbers, so that the shooter still knows how many clicks he has misadjusted, even after several turns, by simply reading it. Replacing the labeling by the user, which is essential for exact distance information when changing ammunition, is not so easy due to the design. 9062934 (B1) PRESLEY MICHAEL [US]
8. 8. An electronic solution: telescopic sight with built-in laser rangefinder and camera, which records the target image and displays it again on a display, and a microprocessor uses the necessary inputs to calculate the height of the target image at which the crosshairs or the target point is and displays it there. E.g. the Burris Eliminator I-IV. Disadvantage: Due to the fact that it is shown on a small display, the target image and the target point are not as sharp and detailed as with rifle scopes with high-quality optical lenses and the magnification is not sufficiently high. For a sports shooter or sniper, this level of accuracy is not enough. Furthermore, the programming of these variants is a bit complicated, since one has to find out some values that are of important ballistic meaning in order to be able to calculate the trajectory of the projectile. E.g. the ballistic coefficient, bullet weight, the velocity of the bullet just after the muzzle. Another possibility would be to look for your ammunition type in very long ammunition lists, which is provided with a coded number that you then have to enter into the scope. This puts many non-technical people off. Furthermore, with these variants it is usually not possible to carry out a click adjustment in order to adjust or correct the hit position. The ballistic calculations are based only on theoretical values and are extremely complicated and always lag a little behind reality. For this reason, the calculations are not accurate enough at longer distances, which are often shot in the military or when high accuracy is required for sport shooters. Furthermore, it is not allowed to shoot with illuminated reticles or target points in telescopic sights in German sports disciplines in competitions. But that would be necessary with these telescopic sights so that you could see anything at all.
9. 9. Combination of purely optical telescopic sight with high-quality lenses and sufficiently large magnification as well as built-in range finder, microprocessor, which uses a ballistic program to calculate the height at which the target point should be displayed. This is then shown on a display at the calculated height and reflected in the sighting image. Eg The Swarovski dS However, this variant has the following disadvantages: This solution is usually extremely expensive. The ammunition used has to be programmed in a complicated way and the calculation lags behind reality again. In addition, this version is also prohibited for sport shooters in competitions because of the illuminated aiming point. Furthermore, it is not possible with this model to make a few quick clicks by turning the reticle adjustment, because there are no towers on which neither elevation nor windage corrections can be made. You can set a basic setting by unscrewing a panel and then making the adjustments. This is therefore not suitable for sportive shooting or for long-range shooting or for use in the military field, since constant readjustment must be possible with these required accuracies. Another disadvantage I see is the combination of a telescopic sight and a range finder in one device. For example, if the range finder breaks after the warranty period, a complete telescopic sight would have to be bought again, which is about 10 to 20 times higher than just buying a range finder, as would be possible with separate devices. Vice versa, if only the riflescope broke, you would only have to replace it instead of both. In addition, with separate devices, a hunter can observe the game all the time through the rangefinder without having to have the weapon at the ready for hours, which is very uncomfortable. In addition, there would be a problem of space or you would have to watch the game through an open window all the time. Or another telescopic sight would have to be purchased and carried along. An additional disadvantage when measuring distances is that one hand has to be released from the weapon in order to press the button on the telescopic sight that triggers the distance measurement. It's difficult enough to hold a gun steady enough with two hands to stay on target in the scope. But if you have to detach a hand from it to press the range finder button, it's almost impossible to press the button without losing sight of the target. Even the moment you press the button, a certain amount of force has to be applied, which causes the rifle to shake in that direction again. A light, external rangefinder that is short, small and handy, where the button for measuring the distance is almost always placed in such a way that you can press it without changing the grip, is much better. For game viewing by hunters or enemy spotting by the military, a lower magnification, such as an external range finder, is better than a larger one, as it offers more field of view. This means that more of the environment can be seen in the device. When aiming through a telescopic sight, on the other hand, a slightly higher magnification is more advantageous in order to be able to aim more precisely. That's why you would have to adjust the magnification of the combination device in order not to have a disadvantage in the respective situation. However, this entails further disadvantages. In addition, again, that you would have to take your hand off the rifle to adjust the magnification of the telescopic sight. These are major disadvantages that cannot be used in combat or when hunting.

The SOLUTION of the problem, my invention:

Rough description, including the terminology:

The invention is a round, wide and tall adjustment knob known as a reticle adjustment turret as part of a reticle adjustment. In the preferred version (1A) externally consisting of a sleeve made of, for example, transparent Plexiglas. On it is a sticker that was individually determined by test shots and created only for this rifle and only for this ammunition, which depicts many spirally arranged lines with exact, finely graded distance information in meters or yards. Instead of a sticker, the sleeve can also be directly printed, engraved, etched or provided with the distance information in some other way. Inside the sleeve there is a carrier element, which is provided with an internal thread in type 1. The carrier element is screwed onto the rotating element as in the "nut and screw" principle. If you turn the reticle adjustment turret, the rotating element, which is non-positively connected to the cover, also rotates, but the carrier element, which is held in place by an anti-rotation device, does not. As a result, the carrier element changes its height. The carrier element "carries" in turn an "information carrier". This has the task of transmitting the information obtained inside the sleeve - about the height of the carrier element - through the sleeve to the outside. The height of the carrier element and thus of the information carrier then shows the correct line and thus the currently set distance (via the distance information on the sticker).

Note on the different variations:

The information carrier can transmit this information to the outside through the sleeve in various ways. These different types make up the different versions, which are explained below as version A, B, C, D and E.

In the preferred version (A), this information carrier is a light source attached to the carrier element, preferably an LED. When it is on, it shines through the sleeve, which is made of clear plexiglass, and through the distance sticker on it. Thus, the set distance information is brightly lit. Less advantageous but conceivable are versions with other light sources instead of an LED, either electrical or natural, e.g. via optical fibers, which capture the ambient light. Variants are also conceivable that indicate the correct distance in a different way than with light (version A):

In version (B) a magnet attached to the carrier element is used as an information carrier. This uses magnetism to move a pointer, for example a small window made of magnetic material, which is moved to the correct position on the outside of the sleeve by magnetism and thus displays the correct distance information. So that the pointer does not ver there could be a second plexiglas sleeve over the first one.

Version (C): In this case, the case has a spiral-shaped slot through which a marking part visibly protrudes as an information carrier. For example, a flag, pen or similar that is attached to the carrier element instead of the LED and that marks the currently set distance. So that the sleeve cannot be pulled apart like a spring when it is spirally provided with a slit, you could attach it to a second sleeve, e.g. glue it. The label or label could be attached to the outer sleeve and made transparent at the exact point where the flag is located, for example below the distance information. It looks like the set distance is underlined.

Version (D): In this version it is possible to make the distance information on the sticker transparent and instead of the LED simply attach a bright color or a bright sticker to the carrier element so that it shines through behind the transparent distance information that is currently displayed. In this case, the bright sticker or paint would be the information carrier.

Version (E) could transmit the information electronically, for example by fitting an electronic measuring probe/sensor instead of the LED, which serves as an information transmitter. A measuring strip, for example, is attached spirally to the sleeve so that the sensor can read the position and calculate the associated distance information, for example using a computer chip. This is e.g. shown to the shooter on a display at a suitable place or e.g. transmitted via Bluetooth to his mobile phone and displayed there visually and/or acoustically, e.g. by voice output.

In addition to the different versions (A,B,C,D,E) there are 2 different designs. The difference between the 2nd design and the 1st is explained for better understanding after the description of the preferred design 1, variant (A).

More detailed description of the functionality of the preferred design 1 combined with the preferred version (A):

A rotary element (9), preferably made of aluminium, is fixed with an M5 countersunk screw (21) to the multi-tooth adjustment pin (27) of a telescopic sight (1) with a positive fit due to its internal multi-tooth shape, so that a non-positive connection is established. A rotation of the rotating element (9) thus causes an adjustment of the reticle. On the rotating element (9) with bsw. M24x3 left-hand thread outside, the plastic carrier element (10) with bsw. M24x3 left-hand thread screwed on inside. An information transmitter (14) in this variant as an LED (14.1) is attached to the carrier element (10). The contacts of the LED (14.1) each end in a bore in the carrier element (10). In each of these 2 holes there is a sliding contact consisting of a stainless steel ball (13) and a spring (12), which together with the LED (14.1) contact are each held in position by a grub screw (18) and thus form an electrical connection . The negative connection to the button cell (22) inside is made via one of these sliding contacts via the aluminum rotating element (9). Via the other sliding contact, the co-rotation preventer (6), e.g. consisting of a brass tube and its internal spring (7) and the sliding contact (8) located therein, which rests on the aluminum cover (23) and the switch (25 ) and its spring made the plus contact to the button cell (22). When the switch (25) is closed, this causes the LED (14.1) on the carrier element (10) to light up. An anchor ring (4) is preferably glued to the telescopic sight so that it cannot be rotated. The anti-rotation device (6) is screwed into the anchor ring using a grub screw (5). In addition to its current-carrying function, the co-rotation preventer (6) has the task of preventing the carrier element (10) from co-rotating when the reticle adjustment turret is rotated. To do this, it is inserted in the slightly larger hole in the carrier element (10), so that the carrier element (10) is prevented from turning, but can still be moved up and down. If you now turn the reticle adjustment turret, the rotating element (9) also rotates and as a result the carrier element (10) moves up or down depending on the direction of rotation. Thus, the LED (14.1) also moves up or down. The LED (14.1) shines through the plexiglass sleeve (19) placed over it and the sticker (26) on it, which is provided with exact meter or yard information. The distance information has the same line height as the pitch of the thread, so that the correct distance information is always backlit. The Plexiglas sleeve (19) is held by the aluminum cover (23) sitting on it. This in turn is held by the switch (25), which is tightened with its external thread into the internal thread of the Pom switch holder ring nut (17). The Pom switch holder base plate (15) with external thread is screwed into the threaded ring (17) with internal thread and fixed with the grub screw (18).

The Pom switch holder base plate (15) is screwed to the aluminum rotary element (9) with 4 countersunk screws (16). The two switch holder ele ments are made of Pom (plastic) to prevent a short circuit. The grub screw (24) that is screwed into the cover (23) and engages in the groove of the Plexiglas sleeve (19) and in the groove of the switch holder threaded ring (17) ensures the force-fit connection that is necessary to turn the cover , a rotation of the Plexiglas sleeve and the rotating element (9) and thereby cause the adjustment of the reticle of the telescopic sight. The NBR sealing rings on the already equipped switch (25), the sealing ring (20) around the Plexiglas sleeve (19) and the sealing ring (3) around the anchor ring (4) prevent dust, dirt and water from penetrating. In order to achieve the same purpose and to provide additional protection against twisting, the anchor ring (4) is glued / sealed to the telescopic sight with adhesive and sealing compound. The sealing ring (2) under the anchor ring (4) provides an initial light dirt and water barrier and serves as a support ring on which the plexiglass sleeve (19) rests in a moveable manner.

Description of how design 2 works:

• Das Drehelement(9) ist in dieser Bauform nicht der Alubolzen mit Außengewinde, sondern die Plexiglashülle, die hier ein Innengewinde aufweist. Diese bewirkt bei Drehung des Absehenverstellturmes eine Höhenverstellung des Trägerelementes(10), dass in dieser Version ein Außengewinde aufweist.

Type 2 is identical to type 1 except for the following differences:

• In this design, the rotary element (9) is not the aluminum bolt with an external thread, but the plexiglass cover, which has an internal thread here. When the reticle adjustment turret is rotated, this causes a height adjustment of the carrier element (10), which in this version has an external thread.

1. 1. Allgemein von „einem Gewinde“ statt „Innengewinde“ oder „Außengewinde“ bei dem Drehelement(9) und Trägerelement(10) gesprochen wird.
2. 2. Indem die Bezeichnung „Drehelement“ in Bauform 1 der Alu-Gewindebolzen mit einem Außengewinde ist, und in Bauform 2 die Plexiglashülse, welche ein Innengewinde aufweist.

Both designs (No.1 and No.2) are considered in the main claim by:

1. 1. Generally speaking of "a thread" instead of "internal thread" or "external thread" in the rotating element (9) and carrier element (10).
2. 2. The designation "rotating element" in design 1 is the aluminum threaded bolt with an external thread, and in design 2 the Plexiglas sleeve, which has an internal thread.
