Description

Firearm and methods to improve accuracy

The invention relates to a firearm, in particular a hunting weapon, as used in hunts, which is equipped with a target or sighting, which has a line of sight, and a method for improving the achievable with a firearm accuracy in a shot at a in a horizontal direction moving target, with a sighting line is directed to the target.

For a target that moves with a component of motion in a horizontal direction and transverse to the firing direction, the breakpoint on which the sight line of a sighting device is directed must be held to compensate for the transverse movement of the target during the flight time of a projectile fired with the firearm , Hunting weapons, in particular, are used as firearms, which are used, for example, for driven hunts in which shooting is carried out on game, which moves with a movement component transverse to the firing direction.

The size of the lead depends essentially on the following three parameters: a) speed of movement of the target across the weft direction, b) distance of the firearm to the target, c) Speed of the projectile.

For example, in a driven hunt, the calculation of the Vorhaltes in practice is regularly difficult, since only the speed of the projectile before firing a shot is known, but not the distance of the firearm or the shooter to the target and the speed of the target, here the piece Wild, with the z. B. moved transversely to the firing direction, before delivery of the respective shot. Thus, distances between the game piece on which a shot is fired, and the shooter or the firearm, for example, between 40 and 150 m and speeds of the game wild across the firing direction, for example, between 5 km / h and 45 km / h quite conceivable. The invention has for its object to further develop a firearm with a sighting, which has a line of sight, that with simple technical means to improve the accuracy in a shot to a moving with a component of movement in a horizontal direction and across the firing direction target and a corresponding procedure.

These objects are achieved with the firearm shown in claim 1 and the method recited in claim 15. The firearm according to the invention, which is equipped with a sighting device having a sighting line, comprises a device for detecting a movement of the firearm in a horizontal plane, in particular a device for detecting a pivoting movement of the firearm in this horizontal plane. By horizontal plane is meant the plane in which the firearm must be pivoted by the shooter in order to hold the sighting line on a target moving with a component of movement transverse to the firing direction, for example a passing game. Thus, despite this component of movement, for example, the play of the shooter not a breakpoint based on the direction of movement of Piece must be wild before the latter, but can continue to direct the line of sight on the piece of game, a device for changing the course of the sighting line is provided relative to the weft direction in response to the detected by the means for detecting the movement of the firearm movement.

For this purpose, the device for changing the course of the sighting line is preferably designed such that the course of the sighting line when detecting a movement of the firearm in the horizontal plane is changed by a predetermined angle against the direction of movement. This angle amount is preferably adjustable by the shooter, preferably in a range of 1.2 ° to 1.5 °, more preferably in a range of 0.5 ° to 2.5 °, more preferably in a range of 0 ° to 5, 0 °. Surprisingly, it has been found that in a variety of driven hunting situations setting an angle between 1.2 ° and 1.5 ° is capable of substantially increasing accuracy, although the speed at which a piece of game passes during a hunt on the shooter, and the removal of the piece of game to the firearm at the time of the delivery of the shot - as already mentioned above - can vary greatly. The inventor has recognized that, however, possibly due to the fact that the velocity of the motion components of the piece of game across the weft direction in reality usually varies between 5 km / h and 10 km / h, an angular amount from this angular range is particularly suitable for increasing the accuracy , The sighting device may comprise a telescopic sight.

The sighting device comprising, for example, a telescopic sight can, for example, be mounted so as to be pivotable about a pivot axis extending approximately perpendicularly to the sighting line. The device for changing the course of the sighting line can-preferably-be operatively connected to the scope such that with it the scope can be pivoted about the pivot axis. Additionally or alternatively, the device for changing the course of the sighting line can pivot its course relative to the sighting device about the pivot axis. If the sighting device is a telescopic sight, then the device for changing the course of the sighting line can be arranged between a lens and an eyepiece of the sighting telescope and can have an optical element which determines the course of the sighting line. In other words, the change in the course of the sighting line can be effected by pivoting the sighting device about a pivot axis extending approximately perpendicular to the sighting line relative to the weft direction and / or by changing the course of the sighting line relative to the sighting device.

The device for changing the course of the sighting line preferably has an optical element which determines the course of the sighting line, in particular a mirror, a projection surface or a light source. Thereby, the change of the sighting line by adjusting the optical member can be done in a relatively simple manner. For example, by adjusting a mirror arranged in or on the sighting device or a projection surface, a reticle, a target spike or marking point, such as a glowing point, which is shown in a viewing or visual field of the sighting device and determines the sighting line, can be used Line of fire corresponding matching position arrangement of the point by a preset, that is fixed or a fixed measure aufwei- send, distance are offset laterally, so that the sighting line with respect to the firing line deviates at a predefined angle. Furthermore, by adjusting a light source, for example a light source generating the marking point, the marking point can be displaced by a preset distance from the positional arrangement of the dot corresponding to the firing line. The adjustment of the light source can be done for example by rotating the light source, by a partial darkening of the light source, or by a plurality of independently controllable light sources. The light source is preferably designed as a light-emitting diode. Preferably, the means for changing the course of the sighting line comprises an electrically operable actuator or servomotor. As a result, changing the course of the sighting line can be effected automatically in a particularly simple manner by a motor drive. The servomotor can be designed, for example, as a servomotor with a preset, that is fixed, angular working range. The angle working range therefore specifies the rotary working range of the servo motor and is preferably defined for triggering a predetermined first sighting line, for example a sighting line left-oriented in the visual field, and a predetermined second sighting line, for example a sighting line oriented to the right in the visual field. To operate the servomotor, the sighting device can have an energy store, such as a rechargeable battery. Preferably, to change the course of the line of sight of the actuator or servomotor with an arranged on the sighting adjusting means for adjusting a course of the sight line determining optical marking or display operatively connected and the adjusting means of the servomotor motorized adjustable. As a result, it is possible, for example, to use the automatic change in the course of the sighting line on any commercially available riflescope or target optics. In such riflescopes, the marking or display can be embodied, for example, as a reticle, crosshair or sighting point, which can usually be adjusted via at least one adjustment means, such as an adjusting screw. The adjusting means is usually arranged laterally on a sighting device and can usually act in combination with a counterforce causing spring on the positioning of the marker or display in the horizontal and / or vertical direction. The adjustment is usually carried out manually by calibration of the sighting device according to the firing direction of the weapon, preferably by turning the adjusting screw. The servo motor can be placed in an advantageous embodiment of the adjusting means, for example, by a latching connection thereto or be locked to the sighting device and adjust the adjusting means in response to a control. The arrangement of the servo motor can thus preferably a Dre- hen the adjusting screw and subsequently cause a displacement of the marking or display in the field of view or field of view of the sighting device and a displacement of the sighting line. Preferably, the means for changing the course of the sight line on at least one light source, which is suitable in a field of view of the sighting at least two, for example, in a calibration presettable and fixed when using the weapon, substantially horizontally side by side and spaced from each other and arranged one The light source can be controlled as a function of the movement detected by means of the device for detecting the movement of the firearm in such a way that only one luminous spot previously assigned to the respectively detected direction of movement is generated and the other luminous element is generated. points are unlit or 'unproven'. In other words, the means for changing the course of the line of sight at least two in a field of view of the sighting device by means of at least one light source independently representable, fixed, and each have a course of the sight line defining luminous points, which are controlled depending on the detected movement direction for lighting. As a result, changing the sighting line can take place in a particularly simple manner solely by activating a light source for illuminating a predefined luminous spot or a reflection element for mirroring a light beam causing the luminous spot. Such a configuration is preferred, for example, in a sighting device, which is designed as a compact reflex sight. The luminous spot does not necessarily have to be in the form of a dot, but can have any desired shape, for example a reticle, reticule or a point surrounding it by a circle. Furthermore, the luminous point can be white, black or shown in any color. Particularly preferably, a luminous dot arranged centrally in the weft direction has a different color than a luminous spot which deviates from the weft direction. In the present case, the term representable is to be understood as indicating or lighting up in the field of view, for example, a light projecting onto a transparent projection surface, such as a glass surface or lens, can be detected. fender light beam on the projection surface effect the image of a light spot. Advantageously, a total of three luminous points, that is, a second focal point offset to the left and a third illuminated opposite to the firing line third luminous point can be generated independently of each other on a projected in the field of view of the sighting device projection, a always only one of the luminous dots is generated or illuminated and the remaining luminous points are not generated or unlit. The luminous dots are preferably arranged substantially horizontally next to one another and may have a preset or fixed spacing, or a fixed positional arrangement relative to each other. Preferably, the first and the second luminous point as well as the second and the third luminous point each have the same distance from one another. Depending on the detection of a movement of the firearm, the second luminous point or the third luminous point can thus be generated or light up, during which time the two respectively other luminous points remain unlit. As a result, a shooter can bring the sighting line defined by the generated luminous point into alignment or coincidence with a target, and due to the weft direction now deviating from the sighting line, provision for a moving target can be taken into account automatically. For example, when pivoting the weapon from right to left, as may occur when the target moves from right to left, the right staggered third luminous point is generated or illuminated; upon pivoting of the weapon from left to right, the second offset point located on the left is correspondingly generated. For operating the at least one light source, the sighting device can have an energy store, such as a rechargeable battery.

Preferably, a plurality of separate light sources are arranged in the sighting device, each of which can generate a luminous spot. In other words, each luminous point can be generated by means of a separately formed light source. As a result, the change of the sighting line can be effected solely by an electronic control, in particular without a movement of two components relative to one another and in particular without a motor-driven movement, that the sighting device is particularly inexpensive to manufacture, particularly robust and durable and is particularly energy-saving operable. For controlling each individual light source, an integrated circuit can be provided. As a result, changing the sighting line can be effected in a particularly simple manner, namely solely by electrical activation of a single light source.

The device for detecting the movement of the firearm may comprise an electro-mechanical or electronic motion sensor of known type.

In the inventive method for improving the achievable with a firearm accuracy in a shot on a moving with a horizontal component of movement across the firing direction target, with a sighting line is directed to the target, the course of the line of sight in a shift of the firearm in a horizontal Level, in particular when pivoting in a horizontal plane, changed by a presettable angle amount against the direction of movement. The angular amount is preferably set in a range of 1.2 ° to 1.5 °, more preferably in a range of 0.5 ° to 2.5 °, most preferably in a range of 0 ° to 5.0 °.

The invention will now be further explained with reference to the accompanying drawings, which illustrate three embodiments purely schematically. Show it :

6a shows a detail of a frontal view of the sighting device from FIG. In a first, with reference to FIG. 1 and 2 explained embodiment of the invention comprises a firearm 100, of which purely schematically only part of a barrel 1 is shown, a sighting device 2, which is designed as a telescopic sight. The sighting device 2 defines a sighting line 4, which is shown in phantom in FIG. It is directed to a target 5, which is immovable in FIG. 1 transversely to the weft direction 6, shown by a solid line. In order to hit the target 5 which is immovable transversely to the firing direction, in the view according to FIG. 1, the sighting line 4 and the weft direction 6 must be in coincidence. Neglecting further, causing a deviation between the sighting line 4 and the weft direction 6 Influencing variables, such as the gravitational attraction, wind, etc., so appears a target point 7, i. the point at which the sighting line 4 impinges on the target 5, when looking through the sighting telescope 3 in the middle of a reticle 8 in the scope image shown schematically in Fig. La.

If, as shown purely schematically in FIG. 2, the target 5 then moves from right to left at a speed V according to the plane of the drawing, this results in the target 5 being in contact for the duration between the delivery of the shot and the impingement of a fired projectile from position SO to position Sl. While in the delivery of the shot, the target 5 when looking through the scope 3 in the direction of the line of sight 4 at the point SO, the weft direction must deviate by an angle α in the direction of speed V of the sighting line, so that the projectile target 5 at the position Sl meets. In order to increase the accuracy, in the embodiment of the firearm according to the invention shown in FIGS. 1 and 2, the sighting device about an axis S, which is approximately perpendicular to the sighting line 4, pivotally mounted to the barrel 1. Further, an unrecognizable in the drawing means for changing the course of the sighting line 4 is provided, which is designed such that when detecting a movement of the firearm in a horizontal plane in a direction which should be symbolized by the arrow P, in particular during detection a pivoting movement, by which a shooter moves the firearm when following the moving target with the sighting line, the aiming device 2 is pivoted so far about the axis S, that the weft direction 6 relative to the Vier sierlinie 4 forms a predetermined angle α. The device for changing the course of the sight line is designed such that the angle α can be preset by the shooter. In a driven hunt, an angle value from the range of 1.2 ° to 1.5 ° to be expected by which the weft direction 6 with respect to the line of sight 4 in the direction of movement of the target must lead, so that the projectile, which deals with a movement component transverse to the firing line locomotive at the position Sl meets when the target is targeted in the position so with the line of sight. Referring to Figs. 3 to 4a, a second embodiment of the invention will now be explained. This second embodiment comprises a firearm 200 with a barrel 101 and a sighting device 102, which in turn is designed as a telescopic sight 103. In contrast to the first exemplary embodiment, in the second exemplary embodiment, the sighting device 102 is not pivotable about an axis extending perpendicularly to the sighting line 104 of this sighting device 102, but is arranged fixed relative to the barrel 101 in this respect. Again, an unrecognizable in the drawing means for detecting a movement of the firearm 200 in a horizontal plane, in particular for detecting a pivoting movement P of the firearm 200 in a horizontal plane, and means for changing the course of the sighting line 104 in dependence of the means of Means for detecting the movement of the firearm 200 detected movement relative to the firing line 106 is provided. As by comparison of FIG. 3, which shows the situation at a stationary target 105 in accordance with FIG. 1, with FIG. 4, which, according to FIG. 2, shows the situation with a target 105 moving from right to left at speed V according to the drawing causes the not visible in the drawing means for changing the course of the line of sight that it is displaced within the scope by the angle α with respect to the weft direction 106, the same effect as by the pivoting of the telescopic sight about the axis S in the first embodiment to reach. For this purpose, the means for changing the course of the line of sight within the scope 103 between the eyepiece 109 and the lens 110 may be disposed and a the course of the line of sight 104 determining optical member having with the means for detecting a pivotal movement of the firearm in a horizontal Level is operatively connected. In this embodiment, as shown diagrammatically in FIG. 4a, the target point 107 moves to the right relative to the reticle 108 of the riflescope 103.

In order to increase the accuracy in a moving target 105 in this embodiment, the stopping point of the firearm is to be selected so that the target point 107 is located during the pivoting movement in the direction of the arrow P on the target. Or the whole reticle is shifted and the Target point remains in the center of the reticle. This variant is shown in dashed lines in Fig. 4a.

It is understood that it is also within the scope of the invention to pivot in a detected pivotal movement of the firearm in a horizontal plane both the sighting line 104 within the scope, as well as the scope itself about an axis S relative to the weft direction. This is particularly useful if the sighting line is to be displaced relative to the firing line by a comparatively large angle α which, for example, is not possible solely by a change in the course of the sighting line within the telescopic sight.

FIG. 5 shows a preferred embodiment of the sighting device 102 embodied as a telescopic sight 103 from FIGS. 3 and 4 in a frontal sectional representation. The rifle scope 103 is designed as a commercially available riflescope and has an adjusting means 22 arranged in the longitudinal extent between an eyepiece and a lens. The adjustment means 22 serves to adjust the reticle 108, for example when calibrating the weapon. For the sake of clarity, only the adjusting means 22 arranged in a horizontal plane is shown here; In principle, a riflescope 103 additionally has a further adjusting means (not shown here) in a vertical plane. The adjusting means 22 comprises an adjusting screw rotatably mounted on a housing of the rifle scope 103, which rests with a disposed within the rifle scope 103 end face on a the reticle 108 having component, such as a lens or glass optics. On a side of the glass optics opposite the adjusting screw 22a, a spring element 22b for biasing the glass optics against the adjusting screw 22a is arranged. As a result, the glass optics between the spring element 22b and the adjusting screw 22a is biased against the spring force of the spring element 22b and held movable. When turning the adjusting screw 22a, this can be done by shifting the reticle 108 in a horizontal plane. For automatically changing the sighting line 104 at a moving target 105, as shown for example in Figures 4 and 4a, the sighting device 102, a device 41, which in dependence of detected by means not shown means for detecting the movement of the firearm 200 movement P the sight line 104 changed by means of a change in position of the reticle 108. For this purpose, the device 41 has an actuator 42, in particular an electric servomotor, which is operatively connected via a shaft with the adjusting screw 22a. As a result, adjustment screw 22a can be rotated by the actuator 42 in a predetermined, in particular fixed or fixed dimension, area, driven by a motor, as a result of which the reticle 108 is displaced in a horizontal plane. This can - as in the examples before - the field of vision in the Zielbzw. Impact level by a certain value, such as Im displaced to the side, so that the target sighting shooter automatically holds the weapon. The device 41 may be fastened to the housing of the riflescope 103, for example via a not shown locking connection. To supply power to the actuator 42, for example, an accumulator not shown here can be arranged on the sighting device 102.

FIG. 6 shows a preferred embodiment of a further sighting device 102 in a lateral sectional illustration. The sighting device 102 is essentially formed as a compact reflex sight, which is preferably used in handguns. In this case, the sighting device 102 via a clamping device not shown here on a present unspecified rail, such as a dovetail rail, such as a so-called Weaver or Picatinny rail, above a gun barrel 101 in the longitudinal direction adjustably attached. The sighting device 102 essentially comprises a projection surface 82, which may be formed as a glass optic, such as a transparent pane or lens, a light source 23, for example a light emitting diode, and an optical member or reflection element 43, such as a mirror. A light beam emitted by the light source 23 substantially opposite to a weft direction 106, which in the present case is indicated by a line with arrows. is reflected on the reflection element 43 substantially in the direction of the weft direction 106 and causes when hitting the arranged in a field of view 81 of the shooter projection surface 82 mapping a light spot 21. The light spot 21 shown on the projection surface 82 does not necessarily have the shape have a point, but may by means of a corresponding filtering have any shape, such as a minimized reticle, a crosshair or a point surrounding by a ring. The respective position of the luminous dots 21 on the projection surface 82 can be preset during a calibration process, but is stationary in a hunting use of the weapon 200 and the device 41, in particular unchanged.

In a hunting application of the weapon 200 with the device 41, the luminescent point 21 can be displaced by means of an adjustment of the reflection element 43 in a horizontal plane for automatically adapting the sighting line 104 to a hunting situation, such as a moving target. This takes place according to the invention as a function of a movement P of the firearm 200, which in the present case can be detected by means of the device 11. The device 11 may be formed, for example, as an electromechanical or electronic motion sensor. The adjustment of the reflection element 43 is carried out here automatically by means of the device 41, in particular by means of an electric servomotor 42. As a result, as soon as a movement P of the firearm 200 is detected by the device 11, in particular a pivoting of the weapon 200 in the horizontal plane, sending a Actuation signal to the servomotor 42 and then carried out an adjustment of the reflection element 43 by a predefined angle.

In an alternative embodiment of the sighting device 102, the reflection element 43 may be arranged fixed and a change of the light beam directly by means of or at the light source 23, for example by rotating the light source 23 or darkening a portion of the light source 23rd Furthermore, it can be provided in a further alternative embodiment of the sighting device 102 that the reflection element 43 is designed to be stationary and at least two separate light sources 23 are arranged for generating a respective light point 21a, 21b, 21c. In this particularly preferred embodiment, a servomotor 42 is not required, furthermore, there are no movably arranged components, so that the sighting device 102 is designed to be particularly robust and can be produced particularly inexpensively.

FIG. 6 a shows a detail of a frontal view of the sighting device 102 according to FIG. 6, in particular a section of a viewing angle of a shooter operating the weapon 200 substantially in the weft direction 106. A total of three respective courses of the sighting line 104 can determine on the projection surface 82 Luminous dots 21a, 21b, 21c - in the manner explained above - by means of at least one light source 23 and the reflection element 43 are generated. In the situation shown in FIG. 6a, only the luminous spot 21c is generated by the light beam of the light source 23 shown in dashed line or visible on the projection surface 82. The luminous points 21a and 21b illustrated here only for better understanding are not generated or not visible on the projection surface 82. In this situation, the pivoting of the weapon 200 from the position of the shooter seen from the right to the left in the horizontal plane was previously detected by means of the device 11, and a Ansteuerungs- signal to the servomotor 42 for adjusting the reflection element 43 output such that the illuminated point 21 is shifted from the neutral position 21a to the right in the corrected position 21c, for example, by not illuminating the luminous spot 21a (and the luminous spot 21b) and illuminating the luminous spot 21c. In a sighting of the target 105, not shown by the shooter, therefore, a pivoting of the weapon 200 takes place from right to left, that the luminous point 21c can be optically brought into coincidence or coincidence with the target 105, not shown, and the barrel 101 of the weapon 200th Thus, automatically can have a predefined Vorhalt before the moving target 105. As already explained with reference to FIG. 6, the reflection element 43 may alternatively be designed to be stationary and the change in position of the light point 21 by change of the light beam at the light source 23 or by a plurality of respective light spots 21a, 21b, 21c generating separate light sources 23 are effected.

It should be understood that the scope of the present invention is not limited to the described embodiments and / or the combinations of features shown. In particular, the structure and the design of the sighting device and the device for changing the course of the sighting line can - without changing the essence of the invention - be quite modified.
