Description

The invention relates to a hunting gun, i.e. a hunting gun as used in driven hunts, which is equipped with a target or sighting device that has a line of sight, and a method for improving the accuracy that can be achieved with a gun when shooting a target moving in a horizontal direction with a line of sight aimed at the target.

For a target that moves with a component of motion in a horizontal direction and transverse to the direction of fire, the holdover point at which the line of sight of a sight is aimed must be maintained in order to compensate for the transverse motion of the target during the time of flight of a projectile fired from the firearm .

A large number of weapons, weapon systems and target or sighting devices are known from the military sector, which are operated in combination with processor-controlled target detection and evaluation systems, mostly equipped with radar or laser technology, in order to avoid misfires and to increase accuracy. Such high-tech, processor-controlled weapons and / or target detection systems are for example in U.S. 2014/283429 A1 , the U.S. 2011/162250 A1 and the US 6,252,706 B1 described, but aim at a different application and equipment area and are unsuitable for hunting purposes in particular due to their recording and evaluation methods.

As a firearm, the present invention exclusively relates to hunting weapons that are used, for example, on driven hunts in which game is shot at that moves with a locomotion component transverse to the direction of the shot. To increase accuracy, such hunting firearms can, as is known, be equipped with a sighting device, for example with rear and front sights, a telescope or a reflex sight. In the case of moving targets, the aiming point must be held 'manually' in the direction of movement locally in front of the moving target, even if a sighting device is used.

1. a) Fortbewegungsgeschwindigkeit des Ziels quer zur Schussrichtung,
2. b) Abstand der Schusswaffe zum Ziel,
3. c) Geschwindigkeit des Geschosses.

The size of the reserve is essentially dependent on the following three parameters:

1. a) speed of movement of the target transverse to the direction of the shot,
2. b) distance of the firearm to the target,
3. c) Velocity of the bullet.

In the case of a driven hunt, for example, it is usually difficult to calculate the lead in practice, since only the speed of the bullet before a shot is fired is known, but not the distance of the firearm or the shooter to the target and the speed of the target, in this case the piece Wild, with which z. B. moves transversely to the direction of fire before the respective shot is fired. Thus, distances between the piece of game at which a shot is fired and the shooter or the firearm, for example, between 40 and 150 m and speeds of the piece of game perpendicular to the direction of the shot, for example, between 5 km/h and 45 km/h are quite conceivable.

The invention is based on the object of further developing a hunting firearm with a sighting device that has a line of sight such that, using simple technical means, the accuracy of a shot at a target moving with a movement component in a horizontal direction and transverse to the direction of fire can be increased improve, as well as specify a corresponding procedure.

These objects are achieved with the firearm recited in claim 1 and the recited in claim 15 method.

The hunting gun according to the invention, which is equipped with a sighting device that has a line of sight, includes a device for detecting a movement of the gun in a horizontal plane, in particular a device for detecting a pivoting movement of the gun in this horizontal plane. The horizontal plane means the plane in which the firearm must be pivoted by the shooter in order to keep the line of sight on a target moving with a movement component transverse to the direction of the shot, for example a piece of game passing by. So that, despite this component of movement, for example of the piece of game, the shooter does not have to choose a stopping point in relation to the direction of movement of the piece of game in front of the latter, but can continue to aim the line of sight at the piece of game, a device for changing the course of the line of sight relative to the direction of the shot is dependent the movement detected by means of the device for detecting the movement of the firearm.

For this purpose, the device for changing the course of the line of sight is preferably designed in such a way that the course of the line of sight is changed by a predetermined, in particular fixed, angular amount counter to the direction of movement when a movement of the firearm is detected in the horizontal plane. This angular amount can preferably be adjusted by the shooter, preferably in a range from 1.2° to 1.5°, more preferably in a range from 0.5° to 2.5°, more preferably in a range from 0° to 5 0°. Surprisingly, it has been shown that in a variety of driven hunt situations setting an angle between 1.2° and 1.5° is suitable for significantly increasing accuracy, although the speed at which a piece of game passes the shooter during a driven hunt and the distance of the piece of game to the gun at the time of the Delivery of the shot - as already mentioned above - can vary greatly. The inventor has recognized that, due to the fact that the speed of the movement components of the piece of game transverse to the shooting 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 accuracy .

The sighting device can include a telescopic sight.

The sighting device, for example comprising a telescopic sight, can be mounted so as to be pivotable, for example, about a pivot axis running approximately perpendicularly to the line of sight. The device for changing the course of the line of sight can—preferably—be operatively connected to the telescopic sight in such a way that the telescopic sight can be pivoted about the pivot axis with it.

Additionally or alternatively, the device for changing the course of the sighting line can pivot its course about the pivot axis relative to the sighting device.

If the sighting device is a telescopic sight, the device for changing the course of the sighting line can be arranged between an objective and an eyepiece of the telescopic sight and have an optical element that determines the course of the sighting line. The course of the line of sight can be changed—in other words—by pivoting the sighting device about a pivot axis running approximately perpendicular to the line of sight relative to the firing direction and/or by changing the course of the line of sight relative to the sighting device.

The device for changing the course of the line of sight preferably has an optical element that determines the course of the line of sight, in particular a mirror, a projection surface or a light source. As a result, the line of sight can be changed in a relatively simple manner by adjusting the optical element. For example, by adjusting a mirror arranged in or on the sighting device or a projection surface, a reticle that is displayed in a field of view or field of view of the sighting device and that determines the line of sight, a target pin or marker point, such as a luminous dot, can be changed from one that corresponds to the direction of fire or line of fire Position arrangement of the point by a preset, ie fixed or having a fixed dimension, distance can be offset laterally, so that the line of sight deviates from the line of fire at a predefined angle. Furthermore, by adjusting a light source, for example a light source that generates the marking point, the marking point can be offset by a preset distance in relation to the positional arrangement of the point that corresponds to the line of fire. The light source can be adjusted, for example, by rotating the light source, by partially darkening the light source, or by using a plurality of light sources that can be controlled independently of one another. The light source is preferably in the form of a light-emitting diode.

The device for changing the course of the line of sight preferably comprises an electrically operable actuator or servomotor. As a result, the course of the line of sight can be changed automatically in a particularly simple manner by a motor drive. The servomotor can be designed, for example, as a servomotor with a preset, ie fixed, angular working range. The angular working range thus specifies the rotary working range of the servomotor and is preferably defined for controlling a predetermined first line of sight, for example a line of sight oriented to the left in the field of view, and a predetermined second line of sight, for example a line of sight oriented to the right in the field of view. To operate the servomotor, the sighting device can have an energy store, such as an accumulator.

In order to change the course of the line of sight, the actuator or servomotor is preferably operatively connected to an adjustment means arranged on the sighting device for setting an optical marking or display that determines the course of the line of sight, and the adjustment means can be adjusted in a motor-driven manner by means of the servomotor. As a result, for example, the course of the line of sight can be automatically changed on any commercially available telescopic sight or target optics. In telescopic sights of this type, the marking or display can be designed, for example, as a reticle, crosshairs or sighting point, which can usually be set using at least one adjusting means, such as an adjusting screw. The adjustment means is usually arranged on the side of a sighting device and can usually act on the positioning of the marking or display in the horizontal and/or vertical direction in combination with a spring that causes a counterforce. The adjustment is usually done manually when calibrating the sighting device according to the shooting direction of the weapon, preferably by turning the adjusting screw. In an advantageous embodiment, the servomotor can be placed on the adjustment means, for example locked thereon or on the sighting device by means of a latching connection, and adjust the adjustment means as a function of an actuation. The arrangement of the servomotor can thus preferably cause the adjustment screw to be rotated and, as a result, the marking or display to be displaced in the field of view or visual field of the sighting device and the line of sight to be displaced.

The device for changing the course of the sighting line preferably has at least one light source which is suitable for providing in a field of view of the sighting device at least two, which can be preset for example during calibration and are fixed when the weapon is in use, are arranged essentially horizontally next to one another and spaced apart from one another and each have one To generate or to generate luminous points that determine the course of the line of sight, the light source being controllable as a function of the movement detected by the device for detecting the movement of the firearm in such a way that only a previously detected direction of movement associated luminous point is generated and the respective other luminous points are unilluminated or 'unproduced'. In other words, the device for changing the course of the line of sight can have at least two stationary luminous dots that can be displayed independently of one another in a field of view of the sighting device by means of at least one light source and each determine a course of the line of sight, which can be controlled to light up depending on the direction of movement detected. As a result, the line of sight can be changed in a particularly simple manner simply by controlling a light source for illuminating a predefined luminous point or a reflection element for reflecting a light beam causing the luminous point. Such a configuration is preferred, for example, in a sighting device that is designed as a compact reflex sight. The luminous point does not necessarily have to be in the form of a point, but can have any shape, for example a reticle, crosshairs or a point surrounded by a circle. Furthermore, the luminous point can be shown in white, black or in any desired color. Particularly preferably, a luminous dot arranged centrally in the firing direction has a different color than a luminous dot arranged in a manner deviating from the firing direction. In the present case, the term displayable is to be understood as a display or illumination in the field of vision, for example a light beam impinging on a transparent projection surface, such as a glass surface or lens, can cause a luminous point to be imaged on the projection surface. Advantageously, a total of three illuminated dots, i.e. a first illuminated dot arranged in the line of fire, a second illuminated dot offset to the left relative to the line of fire and a third illuminated dot offset to the right relative to the line of fire, can advantageously be generated independently of one another on a projection surface located in the field of view of the sighting device, with always only one of the luminous points is generated or illuminated and the remaining luminous points are not generated or are unilluminated. The luminous points are preferably arranged essentially horizontally next to one another and can have a preset, in particular fixed, distance from one another or a fixed positional arrangement. The first and the second luminous point as well as the second and the third luminous point are preferably each at the same distance from one another on. Depending on the detection of a movement of the firearm, the second luminous point or the third luminous point can be generated or light up, while the other two luminous points remain unlit. As a result, a shooter can bring the line of sight defined by the generated illuminated dot into line with or overlap with a target and, due to the direction of the shot now deviating from the line of sight, a lead in the case of a moving target can be automatically taken into account. For example, when the weapon is pivoted from right to left, as can occur when the target moves from right to left, the third illuminated dot offset to the right is generated or illuminated; when the weapon is pivoted from left to right, the second illuminated dot offset to the left is correspondingly generated. To operate the at least one light source, the sighting device can have an energy store, such as an accumulator.

Several separate light sources are preferably arranged in the sighting device, each of which can generate a luminous point. In other words, each luminous point can be generated by means of a separately designed light source. As a result, the line of sight can be changed solely by electronic control, in particular without a movement of two components relative to one another and in particular without a motor-driven movement, so that the sighting device can be produced particularly inexpensively, is particularly robust and durable and can be operated in a particularly energy-saving manner. An integrated circuit can be provided to control each individual light source. As a result, the line of sight can be changed in a particularly simple manner, namely simply by electrically controlling a single light source.

The device for detecting the movement of the firearm can comprise an electromechanical or electronic movement sensor of a known type.

In the method according to the invention for improving the accuracy that can be achieved with a firearm when a shot is fired at a If a target moves horizontally with a component of movement transverse to the direction of fire, with a line of sight aimed at the target, the course of the line of sight is changed by a preset angular amount counter to the direction of movement when the firearm is displaced in a horizontal plane, in particular when it is pivoted in a horizontal plane.

The angular amount can preferably be preset in a range from 1.2° to 1.5°, more preferably in a range from 0.5° to 2.5°, very preferably in a range from 0° to 5.0°.

At a first, based on the 1 and 2 The exemplary embodiment of the invention explained comprises a firearm 100, of which only part of a barrel 1 is shown purely schematically, a sighting device 2, which is designed as a telescopic sight. The sighting device 2 defines a line of sight 4 which is 1 is shown in dotted lines. It is aimed at a goal 5 that is in 1 transverse to the firing direction 6, represented by a solid line, is immobile. In order to hit the target 5, which is stationary transversely to the direction of fire, the view according to 1 the line of sight 4 and the direction of fire 6 overlap. If one ignores other influencing variables causing a deviation between the line of sight 4 and the direction of fire 6, such as gravity, wind etc., a target point 7 appears at a glance, ie the point at which the line of sight 4 meets the target 5 through the telescopic sight 3 in the center of a reticle 8 in the in Fig. 1a schematically illustrated telescopic sight image.

Now moves - as in 2 is shown purely schematically - the target 5 with a speed V according to the plane of the drawing from right to left, this means that the target 5 during the period between the firing of the shot and the impact of a fired projectile from position S0 to position S1 relocated. While when the shot is fired, the target 5 appears at the point S0 when looking through the telescopic sight 3 in the direction of the line of sight 4, the direction of the shot must deviate from the line of sight by an angle α in the direction of the speed V, so that the projectile hits the target 5 at the position S1. In order to increase accuracy, the in 1 and 2 illustrated embodiment of the firearm according to the invention, the sighting device about an axis S, which runs approximately perpendicular to the line of sight 4, pivoted to the barrel 1. Furthermore, a device for changing the course of the line of sight 4, which cannot be seen in the drawing, is provided, which is designed in such a way that when detecting a movement of the firearm in a horizontal plane in a direction that is to be symbolized by the arrow P, in particular when detecting a pivoting movement by which a shooter moves the firearm with the line of sight when pursuing the moving target, the aiming device 2 is pivoted about the axis S to such an extent that the firing direction 6 forms a predetermined angle α with respect to the line of sight 4 . The device for changing the course of the line of sight is designed in such a way that the angle α can be preset by the shooter. In a driven hunt, an angle value in the range of 1.2° to 1.5° can be expected as suitable, by which the direction of fire 6 must advance in relation to the line of sight 4 in the direction of movement of the target, so that the projectile, which is moving with a movement component hits a target moving across the line of fire at position S1 when aiming the line of sight at the target in position like this.

Referring to the Figures 3 to 4a a second embodiment of the invention will now be explained. This second exemplary embodiment includes 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 running perpendicularly to the line of sight 104 of this sighting device 102, but is arranged in a fixed manner relative to the barrel 101 in this regard. Again, a device (not visible in the drawing) for detecting a movement of firearm 200 in a horizontal plane, in particular for detecting a pivoting movement P of firearm 200 in a horizontal plane, as well as a device for changing the course of line of sight 104 depending on the Device for detecting the movement of the firearm 200 detected movement relative to the line of fire 106 is provided. How by comparing the 3 that accordingly the 1 the situation with a stationary target 105 shows, with 4 , which according to the 2 the situation with a target 105 moving from right to left at the speed V according to the drawing becomes obvious, the device for changing the course of the line of sight, which cannot be seen in the drawing, causes this line of sight to change within the telescopic sight by the angle α with respect to the Firing direction 106 is shifted in order to achieve the same effect as by pivoting the telescopic sight about the axis S in the first embodiment. For this purpose, the device for changing the course of the line of sight can be arranged inside the telescopic sight 103 between the eyepiece 109 and the lens 110 and can have an optical element that determines the course of the line of sight 104, which is connected to the device for detecting a pivoting movement of the firearm in a horizontal Level is operatively connected. In this embodiment, as in Figure 4a is shown schematically - the target point 107 relative to the reticle 108 of the telescopic sight 103 to the right.

In order to increase the accuracy of hitting a moving target 105 in this exemplary embodiment, the holding point of the firearm must be selected in such a way that the target point 107 is located on the target during the pivoting movement in the direction of the arrow P. Or the entire reticle is relocated and the aiming point remains in the center of the reticle. This variant is in Figure 4a drawn in dashed.

It goes without saying that it is also within the scope of the invention to pivot both the line of sight 104 within the telescopic sight and the telescopic sight itself about an axis S relative to the firing direction when the firearm is detected pivoting in a horizontal plane. This is particularly useful when the line of sight is to be shifted by a comparatively large angle α relative to the line of fire, which, for example, is not possible solely by changing the course of the line of sight within the telescopic sight.

In the figure 5 is a preferred embodiment of the sighting device 102 designed as a telescopic sight 103 from FIGS Figures 3 and 4 in a frontal Sectional view shown. The telescopic sight 103 is designed as a commercially available telescopic sight and has an adjustment means 22 arranged in the longitudinal extension between an eyepiece and an objective. The adjustment means 22 is used to set the reticle 108, for example when calibrating the weapon. For a better overview, only the adjusting means 22 arranged in the horizontal plane is shown here; In principle, a telescopic sight 103 also has another adjustment means in the vertical plane, which is not shown here. The adjusting means 22 comprises an adjusting screw 22a which is rotatably mounted on a housing of the telescopic sight 103 and which, with an end face arranged within the telescopic sight 103, rests against a component having the reticle 108, such as a lens or glass optics. A spring element 22b for prestressing the glass optics against the adjusting screw 22a is arranged on a side of the glass optics opposite the adjusting screw 22a. As a result, the glass optics are movably prestressed and held between the spring element 22b and the adjusting screw 22a against the spring force of the spring element 22b. When the adjusting screw 22a is turned, the reticle 108 can be displaced in the horizontal plane.

For automatically changing the line of sight 104 with a moving target 105, as is the case, for example, in Figures 4 and 4a is shown, the sighting device 102 has a device 41 which changes the sighting line 104 by changing the position of the reticle 108 as a function of the movement P detected by means of a device for detecting the movement of the firearm 200 (not shown). For this purpose, the device 41 has an actuator 42, in particular an electric servomotor, which is operatively connected to the adjusting screw 22a via a shaft. As a result, adjusting screw 22a can be motor-driven rotated by actuator 42 in a predetermined range, in particular a fixed range or a range having a fixed dimension, as a result of which reticle 108 is displaced in the horizontal plane. As a result, as in the previous examples, the field of view in the target or impact plane can be shifted to the side by a certain value, for example by 1 m, so that the shooter aiming at the target automatically holds the weapon up. The device 41 can not be specified, for example, via a be attached to the housing of the telescopic sight 103 by the snap-in connection shown. For example, an accumulator, not shown here, can be arranged on the sighting device 102 for the power supply of the actuating drive 42 .

In the figure 6 a preferred embodiment of a further sighting device 102 is shown in a lateral sectional representation. The sighting device 102 is designed essentially as a compact reflex sight, which is preferably used with handguns. The sighting device 102 is attached via a clamping device, not shown in detail, to a rail, not shown in detail here, for example a dovetail rail, such as a so-called Weaver or Picatinny rail, above a weapon barrel 101 so that it can be adjusted in the longitudinal direction. The sighting device 102 essentially comprises a projection surface 82, which can be designed as glass optics, 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 essentially counter to a shooting direction 106, which is marked here by a line with arrows, is reflected on the reflection element 43 essentially in the direction of the shooting direction 106 and, when it hits it, has the effect of being arranged in a field of vision 81 of the marksman Projection surface 82 depicts a luminous point 21. The luminous point 21 depicted on the projection surface 82 does not necessarily have to have the shape of a point, but can have any shape by means of appropriate filtering, for example a minimized reticle, a crosshair or a point surrounded by a ring . The respective position of the luminous points 21 on the projection surface 82 can be preset during a calibration process, but is fixed, in particular unchanged, when the weapon 200 and the device 41 are used for hunting.

When using the weapon 200 with the device 41 for hunting purposes, the illuminated dot 21 can be adjusted by adjusting the reflection element to automatically adjust the line of sight 104 to a hunting situation, such as a moving target 43 are offset in a horizontal plane. According to the invention, this takes place as a function of a movement P of the firearm 200, which can be detected by means of the device 11 in the present case. The device 11 can be embodied, for example, as an electromechanical or electronic motion sensor. In the present case, the adjustment of the reflective element 43 takes place automatically by means of the device 41, in particular by means of an electric servomotor 42. As soon as a movement P of the firearm 200 is detected by means of the device 11, in particular a pivoting of the weapon 200 in a horizontal plane, a transmission of a Control signal to the servomotor 42 and then an adjustment of the reflection element 43 by a predefined angle.

In an alternative configuration of the sighting device 102, the reflection element 43 can be arranged in a fixed manner and the light beam can be changed directly by means of or on the light source 23, for example by rotating the light source 23 or darkening a partial area of the light source 23.

Furthermore, in a further alternative configuration of the sighting device 102, it can be provided that the reflection element 43 is designed to be stationary and at least two separate light sources 23 are arranged for generating a luminous point 21a, 21b, 21c in each case. In this particularly preferred embodiment, a servomotor 42 is not required, and there are also no movably arranged components, so that the sighting device 102 is of particularly robust design and can be produced particularly cost-effectively.

In the Figure 6a FIG. 12 is a detail of a front view of the sighting device 102 according to FIG figure 6 is shown, in particular a section of a viewing angle of a shooter operating weapon 200 essentially in firing direction 106. A total of three luminous dots 21a, 21b, 21c, each of which determines a course of line of sight 104, can be projected on projection surface 82 - in the manner explained above - by means of at least one light source 23 and the reflection element 43 are generated. in the in Figure 6a The situation shown is only the luminous point 21c represented by the dashed line Light beam generated by the light source 23 or visible on the projection surface 82 . The light points 21a and 21b shown here only for better understanding are not produced or are not visible on the projection surface 82 . In this situation, device 11 previously detected a pivoting of weapon 200 from right to left in the horizontal plane, viewed from the shooter's position, and a control signal was output to servomotor 42 for adjusting reflection element 43 in such a way that illuminated dot 21 went out is shifted to the right from the neutral position 21a to the corrected position 21c, for example by not illuminating the luminous point 21a (and the luminous point 21b) and illuminating the luminous point 21c. When the shooter sights target 105, not shown, weapon 200 is pivoted from right to left in such a way that illuminated dot 21c can be brought into visual agreement or overlapping with target 105, not shown, and barrel 101 of weapon 200 can thus automatically have a predefined lead in front of the moving target 105 . As already to figure 6 As explained above, the reflection element 43 can alternatively be designed to be fixed and the change in position of the luminous point 21 can be effected by changing the light beam at the light source 23 or by several separate light sources 23 each producing a light point 21a, 21b, 21c.
