State of the art

Such systems are from the DE 10 2016 103 572 A1 known.

When hunting, wild animals are often shot at with a handgun, particularly a rifle. In order to check whether the game was successfully hit by a shot, the so-called target point (i.e. the location of the game at the moment of the shot) must be sought after the shot has been fired. There either the hunted game can be found or, if the game was missed completely, the entry point of the projectile. If the game has been shot but not fatally hit, traces can be found at the point of attack that allow a search for animal welfare reasons to track down and finally kill the injured game.

The search for the point of attack is often a challenge, especially when hunting in confusing terrain or when shooting from a long distance. Even if the game is clearly visible before the shot is fired, the hunted or fleeing animal can literally be swallowed by the vegetation. If the shooter tries to simply memorize the target point immediately after the shot has been fired, he often misjudges the distance and / or the exact direction of the shot. However, various devices and methods are known from the prior art, which are intended to make it easier to find the connection point.

The generic DE 10 2016 103 572 A1 For example, discloses a system with a connection finder function in which several different devices are used that communicate with one another via data interfaces. Using a GPS location device or GPS location module, which can be integrated into a smartphone, for example, the own location is first determined. If the shooter carries the location device or the device into which the location module is integrated, the current location (the current position) of the shooter and thus his rifle can be determined. If the shooter aims at a target object (a game to be shot), the distance of the shooter to the targeted object is determined by means of a range finder. The range finder can also be designed as a separate device. For example, the range finder can be a laser range finder which has a display for displaying the measured distance and a compass. Alternatively, the range finder can be designed as a module, for example a telescopic sight, which, in addition to the range finder, has a display for displaying the measured distance and a compass. The compass is used to determine the direction in which the target object is located. Finally, the angle of inclination of the rifle in the observation direction in relation to the direction in which the force of gravity acts is determined by means of an inclination sensor. The own location, distance and direction data, whereby the term “direction” can include both the compass direction and the inclination, can be determined when the shot is fired or immediately before or after it and are then - if not measured by the smartphone itself - transmitted via data interfaces to the smartphone, which then uses a computing unit to calculate the location coordinates of the connection point from the location, distance and direction data. All data can be stored in a memory unit. The calculated location coordinates are provided for a navigation function, in particular a smartphone app or a navigation device. The navigation function takes over the navigation to the connection point.

The disadvantage of this system is that for the determination of the various parameters that are necessary to calculate the location coordinates of the connection point (namely the own location, distance and direction data), different devices are used. On the one hand, the shooter consequently has to carry several devices with him in order to be able to better localize a target point when hunting. On the other hand, when using different devices, the own location of the individual devices can deviate from each other at the crucial moment of the parameter measurement, i.e. the determination of the own location, distance or direction data, so that the measured parameters deviate from the actual parameters of the connection point, whereby the individual ones are different Accumulate deviations as measurement errors when calculating the location coordinates of the connection point from the various parameters. Circumstances other than the possibly different location of the different devices can also contribute to a measurement inaccuracy. For example, the arrangement of the compass on the telescopic sight known from the prior art leads to errors in the direction measurement. The reason for this is that the telescopic sight is mounted on the rifle directly above the barrel of the rifle, that is to say directly above that part of the rifle through which the projectile is guided when the shot is fired. The barrel of the rifle is usually made of a ferromagnetic material that negatively affects the direction measurement of the compass.

From the DE 10 2012 003 124 B3 in turn, an optical observation device is known by means of which a user can capture a target and be navigated to the target location. The device is suitable for use in hunting, in particular for finding a connection point. A location determination unit for determining the current location of the device and thus of the user is integrated into the optical observation device. In addition, it has an electronic compass for determining the compass direction of the observation direction as well as an optoelectronic distance meter for determining the distance to a targeted target. In addition, the angle of inclination of the device in the direction of observation in relation to the direction of gravity can be detected with an inclination sensor. The observation device also has a computing unit which can calculate the location coordinates of the targeted target from the determined own location, distance and direction data. All data can be stored in a storage unit of the observation device. The calculated target direction vector and the remaining distance to the target are shown on a display so that it is easy to navigate to the target. The distance and direction measurement can be activated by actuating a manual switch or by detecting the approach of the device to the eyes by means of a proximity sensor in the eyepiece area.

The use of this known device for finding connection points when hunting is also disadvantageous, since the shooter has to carry another device with him in addition to his rifle. If the shooter wants to determine the location coordinates of the target point with this known device, the measurement of the own location, distance and direction data cannot take place at the same time as the shot. The shooter can only take the measurement immediately before or after a shot is fired by putting the rifle aside and aiming the target through the observation device. For this, the shooter has to remember the connection point, which leads to inaccuracies in the determination of the location coordinates of the connection point.

Task

It is the object of the present invention to specify a system for finding a connection point which enables the location coordinates of the connection point to be determined more precisely.

Statement of the invention

This object is achieved in connection with the features of the preamble of claim 1 in that the compass is arranged on or in the butt of the rifle.

Preferred embodiments are the subject of the dependent claims.

According to the invention it is provided to arrange the compass on or in the butt of the rifle. The piston is usually made of a non-ferromagnetic material. In contrast to the usually ferromagnetic material of the rifle barrel, the material of the piston does not negatively influence the direction measurement of the compass. The arrangement of the compass on or in the rifle butt consequently leads to a higher measurement accuracy when determining the compass direction in which a shot was fired and in which a target point is accordingly located. This contributes to a more precise determination of the location coordinates of the connection point.

The compass is preferably arranged on or in an exchangeable shaft cap. A butt plate is usually an interchangeable accessory for a rifle in the form of a cap that can be attached to the free end of the butt, the so-called buttstock. The arrangement of the compass on or in a butt plate ensures that the compass is arranged sufficiently far away from the ferromagnetic rifle barrel. It also enables rifles to be retrofitted with a compass on the butt.

The compass can be gimbaled. This means that the compass can be mounted on or in the butt or on or in the butt plate in such a way that its spatial orientation is essentially fixed in relation to the vertical direction specified by gravity and is independent of a change in the spatial orientation of the rifle. This is advantageous because the measuring accuracy of the compass drops when it is tilted from its horizontal position. Due to the cardanic suspension, the compass cannot be tilted from its horizontal position, which further contributes to a higher measuring accuracy of the compass and as a result enables a more precise determination of the location coordinates of the connection point.

Additionally or alternatively, the compass can be designed as an electronic compass in which a second inclination sensor and a magnetic field sensor coupled to the second inclination sensor are integrated. The coupling of the second inclination sensor to the magnetic field sensor allows a measurement inaccuracy of the compass to be compensated for by its own inclination with respect to the direction of gravity, provided the compass is not gimbaled. Consequently, the coupling of the second inclination sensor to the magnetic field sensor of the compass can also enable the location coordinates of the connection point to be determined more precisely.

In a preferred development of the invention, the first inclination sensor is identical to the second inclination sensor. This means that the same inclination sensor, which compensates for the measurement inaccuracy of the compass by its own inclination in relation to the direction of gravity, is also used to determine the inclination angle of the rifle in the direction of the point of attack. The dual function of the inclination sensor can save costs for an additional inclination sensor.

In addition, a sound sensor and / or a shock sensor can be included as a shot sensor for detecting a shot, which activates the storage of the current location, direction and distance data as connection point data in the memory unit when a shot is detected. The storage of the location, direction and distance data of the attachment point is thus triggered by the detection of a shot. The close temporal relationship between the shot detection and the parameter storage enables a more precise determination of the location coordinates of the target point. The shot can be detected acoustically, for example, by means of a sound sensor that detects the sound that is generated during a shot. It is also conceivable to detect the shot by registering the recoil by means of a shock sensor.

A trigger switch is advantageously arranged on the butt of the rifle, which, when actuated, activates the storage of the current location, direction and distance data as plausibility and / or verification data in the memory unit. If necessary, actuation of the trigger switch can also trigger the determination of the current location, direction and distance data. Alternatively, the current location, direction and distance data can be measured permanently or activated by actuating a second trigger switch. With the help of the trigger switch, the activation of the storage (and possibly the determination) of the current location, direction and distance data can be done manually. In this way, location, direction and distance data can be collected and stored as plausibility data in the memory unit even before a shot is fired. It makes sense for the shooter to operate the trigger switch when he aims at a target object and wants to fire a shot shortly afterwards. The computing unit can then compare the collected plausibility data with the connection point data and check whether the connection point data are plausible, that is to say credible. If the point of contact data deviate significantly from the plausibility data, because the rifle was panned by the shooter at the moment the shot was fired, for example, the point of contact data can be classified as implausible and discarded. The plausibility data can, for example, be averaged from the last three to ten parameter measurements before the shot detection. Averaging several values increases the reliability of the plausibility data.

As an alternative or in addition, after a shot has been fired, further own location, direction and distance data can be collected and stored as verification data in the memory unit. Immediately after the shot has been fired, the shooter can continue to aim the rifle in the direction of the shot and press the trigger switch to verify the target point data. Alternatively, after firing the shot with the rifle at the ready, the shooter can visually follow the possibly fleeing wild animal and hold the animal's escape route by operating the trigger switch.

The trigger switch can be designed as a shoulder switch and / or as a finger switch. The trigger switch can therefore be arranged on the rifle in such a way that, when the shooter holds the rifle at the ready, it can be actuated either with his shoulder or with his finger. The shoulder switch is advantageously arranged on the butt of the rifle in such a way that it can only be activated by the Holding the rifle at the ready comes into contact with a shoulder of the shooter and is consequently automatically actuated in the ready position.

Conveniently, two or more trigger switches are present, of which at least one can be actuated with a shoulder and at least one with a finger when the shooter is aiming at or shooting a target in the stop position. For example, a first trigger switch can serve to activate the determination of the current location, direction and distance data. When actuated, a second trigger switch can activate the storage of the current location, direction and distance data as plausibility data and a third trigger switch can activate the storage of the current location, direction and distance data as verification data. However, it is also conceivable to link the various functions with one another in such a way that only one or two trigger switches are required to determine and store the data. If there is only one trigger switch, the stored location, direction and distance data can be assigned either as plausibility data or as verification data based on the time interval between their recording in relation to the connection point data stored during a shot detection. However, it is particularly advantageous if the determination of the current location, direction and distance data and their storage as plausibility data are activated by actuating a first trigger switch, which is designed as a shoulder switch, while the storage of said data as verification data by actuating a second trigger switch, which is designed as a finger switch, is triggered. This means that whenever the shooter holds his rifle at the ready, the determination of the current location, direction and distance data and their storage in the memory unit as plausibility data is automatically triggered by holding the rifle at the ready. To save said data as verification data, however, the shooter must actively operate the finger switch. He can therefore trigger this process if necessary.

Furthermore, the location determination unit, the compass, the range finder, the first inclination sensor, the computing unit, the storage unit, the navigation unit and / or the shot sensor can be fixed on the rifle or integrated into rifle components. While said components have to be integrated into rifle components during manufacture, rifles can also be retrofitted by subsequently fixing said components to the rifle. The integration or fixation of all components in or on the rifle has the enormous advantage that the shooter only needs one device to shoot and to reliably find the target point. So he doesn't have to deal with multiple devices. In this way, all parameters of the connection point are determined from exactly the same own location, which allows the location coordinates of the connection point to be determined more precisely than if each parameter is measured by another device with a - albeit slightly - different own location.

A display for displaying the location coordinates, the route to the connection point, the own location, the direction and / or the distance data is also preferred. The display can also be fixed to the rifle or integrated into rifle components. With the help of the display, location coordinates, route, own location, direction and / or distance data can be displayed, read by the shooter and, if necessary, checked. In particular, the direction and distance data can be verified by the shooter on the basis of his sensory impressions. Apart from this, the representation of the calculated location coordinates of the connection point and / or the calculated route to the connection point is necessary if the navigation to the connection point by means of the navigation unit takes place exclusively through visual commands, which has the advantage that the quiet in the hunting area is not unnecessarily disturbed and game is possibly scared away. The representation of the location coordinates and / or the route can, however, also be used to support acoustic navigation.

The display is particularly preferably arranged in a sighting device of the rifle and / or on the top of the rifle, for example on the sighting device, on the butt or on the buttstock. In this case, all data can be shown in just one display, which is arranged either in a sighting device of the rifle or on the top of the rifle. Alternatively, all data can be presented in two displays, the first of which is arranged in a sighting device of the rifle and the second of which is arranged on the top of the rifle. However, it can also be provided that some data, for example the own location, direction and / or distance data, are displayed in a display in a sighting device of the rifle, while the location coordinates of the connection point and / or the route to the connection point are displayed the top of the rifle. The arrangement of the display in a sighting device of the rifle enables the shooter to control the parameters while aiming at a target. The arrangement of the display on the top of the rifle, on the other hand, makes it easier for the shooter to navigate to the target point, provided that this is done using visual commands. This means that the shooter does not have to keep his rifle at the ready while navigating to the target point. Instead, he can Carry your rifle in a more comfortable position on the way to the target point and follow the route to the target point by simply looking at the top of the rifle. In addition, the shooter can quickly take up his rifle again if he encounters a (shot) wild animal.

The computing unit and / or memory unit is advantageously connected to a first data interface, via which the location coordinates, own location, direction and / or distance data can be transmitted to and / or received from an external device. The computing unit and / or storage unit can receive and / or transmit individual or multiple data via the data interface. This is necessary if the determination of the own location, direction and / or distance data, the calculation of the location coordinates of the connection point and / or the navigation to the connection point are not carried out by the same device. But even if all functions are combined in one device, a data interface can be useful for transferring the various data. For example, the shooter can save the data on an external device or send it to third-party devices. It is also conceivable that the shooter makes the data available to a limited group of third parties with the help of an Internet server, who are present at the hunt and want to navigate to the connection point with their own navigation units. The data interface can be designed, for example, as a Bluetooth, WLAN, mobile radio or near-field communication interface.

In a preferred development of the invention, a laser marker is also included, which has a laser for visual marking of the connection point, a second data interface via which the location coordinates, local, direction and / or distance data can be received from the storage unit, and a motorized alignment unit for Aligning the laser to the connection point. By means of the additional laser marker, the connection point can be marked in a visually perceptible manner with a laser, whereby the connection point can be found more easily. This applies in particular, but not exclusively, in the event that the navigation unit fails. The laser marker can receive the location coordinates, own location, direction and / or distance data from the memory unit via the second data interface. If the laser marker is positioned directly next to the shooter, it can be sufficient if only the determined direction of the compass, in which the point of attachment lies, and the angle of inclination of the rifle in the direction of the point of attachment are transmitted to the second data interface via the first data interface. However, the laser marker can also be set up further away from the shooter, for example in an open field, while the shooter shoots from a hiding place (such as a bush). Then the laser marker would have to have its own location determination unit for determining the location and the (three-dimensional) location coordinates of the connection point or the location, direction and / or distance data of the connection point would have to be transmitted via the first data interface to the second data interface, at least in the latter case the laser marker would have to have its own computing unit in order to calculate the (three-dimensional) location coordinates of the connection point itself from the connection point data. When the laser marker has received the data, the laser is automatically aligned to the connection point by means of the motorized alignment unit. If the laser is switched on, it marks the connection point so that it can be found without a navigation unit.

Optionally, the laser marker can have the range finder, wherein the determined distance data can be transmitted to the first data interface via the second data interface. This can be useful if the laser marker is positioned directly next to the shooter.

It can be problematic if the location-determining unit fails during a navigation to a connection point (i.e. if, for example, a GPS location-finding unit can no longer receive a GPS signal), since knowledge of the current home location is necessary for navigation. This can lead to difficulties in finding the connection point in particular if the shooter had to leave the immediate, shortest route to the connection point due to obstacles. In such a case, however, the current own location can be determined by means of a system according to the invention if a part of the distance from the location of the firing of the shot to the point of attack has already been covered. However, this requires that the system include a trigger switch as described above. In order to determine one's own location during a navigation to a connection point in the event of a failure of the location-determining unit, a reference point must first be aimed at, the location of which is known. This can in particular be the location of the shot, whose absolute (GPS) location coordinates were determined at the moment of the shot using the (still) functional location determination unit and stored in the memory unit or whose location coordinates are otherwise known, for example as relative location coordinates in relation to the location coordinates of the connection point. The determination of the direction and distance data from the current location to the reference point is then activated manually by actuating the trigger switch. The Computing unit the location coordinates of the current own location on the basis of the known location of the reference point as well as the determined direction and distance data from the current own location to the reference point. Finally, the location coordinates of the current home location are fed into the navigation unit. In this way, the navigation that has already started can be continued even if the location determination unit fails.

Further details and advantages of the invention emerge from the following specific description and the drawings.

Description of preferred embodiments

1 shows a schematic representation of a first embodiment of a system according to the invention 10 to find connection points X at the Hunt. A marksman (not shown) aims his rifle 20th on a wild animal 14th . To the point of contact after the shot has been fired X , i.e. the location of the wild animal 14th at the moment the shot is fired, easier to find with the help of the system according to the invention 10 the location coordinates of the connection point X calculated and made available to a navigation unit. The navigation unit in turn calculates a route R. to the connection point X that the shooter can use to navigate there.

To the location coordinates of the connection point X To be able to calculate, various parameters must first be determined. To determine the required parameters, the system includes 10 several measuring instruments, more precisely a location unit 22nd a compass to determine your own location 24 to determine the direction in which the connection point X a range finder 26th to determine the distance E. from the range finder 26th to the connection point X and a first tilt sensor 28 to determine the angle of inclination a of the rifle 20th in the direction of the connection point X . The parameters determined by the measuring instruments are transmitted to a processing unit, which uses the determined own location, direction and distance data to determine the location coordinates of the connection point X calculated. The calculated location coordinates and the determined own location, direction and distance data can be stored in a memory unit and transmitted to the navigation unit.

For a more precise determination of the location coordinates of the connection point X to enable, it is provided according to the invention that the compass 24 , as in 2 easily recognizable, on or in the piston 201 of the rifle 20th is arranged. This is particularly beneficial as the piston 201 - in contrast to the barrel of a rifle 202 - usually consists of a non-ferromagnetic material and thus the direction measurement of the compass 24 not negatively affected. The compass is preferred 24 on or in an exchangeable butt plate 209 arranged. This is the compass 24 far enough away from the ferromagnetic gun barrel 202 arranged. In addition, rifles can be retrofitted in this way 20th with one on the piston 201 arranged compass 24 enables. The compass 24 can be gimbaled (not shown) in order to exclude measurement inaccuracies of the compass due to tilting from its horizontal position. Alternatively or additionally, the compass 24 be designed as an electronic compass, in which a second inclination sensor and a magnetic field sensor coupled to the second inclination sensor are integrated. In this case, as shown here, is the first tilt sensor 28 preferably identical to the second inclination sensor. That is, the same tilt sensor 28 showing the measurement inaccuracy of the compass 24 compensated by its own inclination in relation to the direction of gravity, it is also used to determine the inclination angle a of the rifle 20th in the direction of the connection point X .

Furthermore, a sound sensor and / or a shock sensor can be included as a shot sensor for detecting a shot, which activates the storage of the current location, direction and distance data as connection point data in the memory unit when a shot is detected (not shown).

Is preferred on the piston 201 of the rifle 20th a first trigger switch designed as a shoulder switch 205 arranged. When pressing the shoulder switch 205 the determination of the current location, direction and distance data and their storage as plausibility data are activated. There is also a finger switch trained, second trigger switch 206 on the rifle 20th arranged which, when actuated, triggers the storage of said data as verification data. In this way, location, direction and distance data can be collected and saved before or after a shot has been fired. The function of the shoulder switch 205 causes whenever the shooter uses his rifle 20th holds at the ready, the determination of the current location, direction and distance data and their storage in the memory unit as plausibility data automatically by holding the rifle 20th be triggered in the stop. In order to save said data as verification data, however, the shooter must actively use the finger switch 206 actuate. He can therefore trigger this process if necessary. The finger switch 206 is preferably in the immediate vicinity of the fume cupboard 204 arranged, as it is easily accessible there for the shooter and can be operated quickly after a shot.

In addition, - in addition to the compass 24 - the location unit 22nd , the range finder 26th , the first tilt sensor 28 , the computing unit, the storage unit, the navigation unit and / or the shot sensor on the rifle 20th fixed or integrated into rifle components (not shown). As a result, the shooter only needs one device to shoot and to reliably find the target point X .

Favorably are a first advertisement 207 in a sighting device 203 of the rifle 20th and a second display 208 at the top of the rifle 20th arranged. 3A Figure 13 shows a view of the first display 207 , by means of which some data, for example the own location, direction and / or distance data, can be displayed. 3B FIG. 13 shows a top view of the rifle of FIG 1 , with the second ad 208 is easy to see. The second ad 208 is preferably used to display the location coordinates of the connection point X and / or the route R. (e.g. direction and distance) to the connection point X . The arrangement of the first ad 207 in a sighting device 203 of the rifle 20th allows the shooter to control the parameters while aiming at a target. The arrangement of the second display 208 at the top of the rifle 20th however, it makes it easier for the shooter to navigate to the point of attack X at gunpoint.

The computing unit and / or memory unit is advantageously provided with a first data interface 210 connected, via which the location coordinates, own location, direction and / or distance data can be transmitted to and / or received by an external device (see Sect. 4th ).

4th shows a schematic representation of a second embodiment of a system according to the invention for finding connection points during hunting. The system for finding connection points X when hunting can use an additional laser marker 30th include that of a laser 301 for visual marking of the connection point X , a second data interface 302 , via which the location coordinates, own location, direction and / or distance data can be received from the storage unit, and a motorized alignment unit 303 for aligning the laser 301 on the connection point X having. The additional laser marker 30th can serve as the connection point X with a laser 301 to mark visually perceptible, which can be particularly helpful if the navigation unit fails. The laser marker 30th can via the second data interface 302 the location coordinates of the connection point X that receive home location, direction and / or distance data from the storage unit. When this happens, the laser can 301 by means of the motorized alignment unit 303 automatically to the connection point X be aligned. Will the laser 301 switched on, it therefore marks the connection point X so that it can be found without a navigation unit. Optionally, the laser marker 30th the range finder 26th have, the determined distance data via the second data interface 302 to the first data interface 210 are transferable.

If the location unit is during a navigation to a connection point X fails, this can in particular lead to difficulties in finding the connection point X lead when the shooter is due to an obstacle 12th the immediate, shortest route R. to the connection point X had to leave (s. 1 ). In this case, however, the current own location can be as follows by means of a system according to the invention 10 to be determined: If already part of the route R. from the place where the shot was fired to the point of contact X has been covered, it must first be aimed at a reference point whose location is known. This can in particular be the location of the shot, its absolute location coordinates at the moment of the shot by means of the (still) functional location-determining unit 22nd were determined and stored in the memory unit or whose location coordinates are otherwise known. The direction and distance data from the current location to the reference point is then determined by actuating the trigger switch 205 , 206 activated manually. The computing unit then calculates the location coordinates of the current own location on the basis of the known location of the reference point and the determined direction and distance data from the current own location to the reference point. Finally, the location coordinates of the current home location are fed into the navigation unit. So it can already started navigation even if the location unit fails 22nd to be continued.

Of course, the embodiments discussed in the specific description and shown in the figures represent only illustrative embodiments of the present invention. In the light of the disclosure here, a person skilled in the art is provided with a broad spectrum of possible variations.
