Description

[0001] The present invention generally relates to a target assembly for automatic hit analysis, as defined in the preamble of claim 1. In particular, such a target assembly provides hit detection, for example, by means of a corresponding sensor, as well as a hit indication for the shooter, for example, by means of a corresponding tilting mechanism of the target. Such target assemblies are typically used at military or police shooting ranges; however, they can also be used at hunting shooting ranges.

[0002] The publication DE 10 2016 003 152 A1 describes a method and device for detecting hits on targets. A bandpass filter is tuned to the frequencies typically generated when a bullet penetrates the target. The threshold at which a hit is selected is adjusted for each event using a second filter and / or across the entire amplitude of the detected signal, so that a hit is only selected if the typical frequencies of a hit exceed a minimum amplitude relative to the entire amplitude of the signal or the amplitude of a specified frequency range. This is intended to detect misses, as well as hits in areas of the target that are a relatively large distance from the sensor.

[0003] From the publication DE 10 2008 059 189 A1, a hit sensor for targets is known. It comprises a piezoelectric sensor in a housing and downstream processing electronics. The housing is designed to resonate in the range of a higher harmonic of the hit excitation frequency, and the processing electronics are configured to generate a hit signal upon detection of the resonant frequency. This is intended to achieve hit signal triggering and discrimination even after narrow misses.

[0004] DE 41 06 040 C2 discloses a method for determining the speed of bodies flying at least at the speed of sound, in particular projectiles. The pressure of the head wave of the flying body is recorded at at least two sensors arranged in the direction of the flight path and at a defined distance from each other. The time interval between the pulses generated by the sensors is recorded and determined as a measure of the speed of the body, taking into account the distance between the sensors.

[0005] The publication KR 10 1 150 751 B1 shows a device for an electronic dart game.

[0006] The document US 2012 / 0091660 A1 shows a target impact point detection system.

[0007] The document US 2017 / 0370684 A1 shows a portable targeting device which has a threat target and a non-threat target which is positioned near the threat target.

[0008] The document US 2022 / 0276028 A1 shows a target which is heated by a heat source.

[0009] The existing solutions have the disadvantage of being complex to manufacture and comparatively expensive, making them unsuitable for widespread use of targeting systems with differentiated hit detection. In particular, they cannot provide the shooter with graduated feedback regarding the point of impact and impact in real time.

[0010] It is the object of the present invention to provide a target arrangement which is simple and cost-effective to produce and which reliably ensures immediate information about the target effect of a hit, ie for example whether a hit has a potentially lethal effect or not.

[0011] This object is achieved by technical objects according to independent claim 1. Technically advantageous embodiments are the subject of the dependent claims, description and drawings.

[0012] The essence of the invention is as follows: a target assembly for automatic hit analysis, which has an acoustic sensor and a first carrier plate. Furthermore, the target assembly has at least one first attachment plate, wherein the first attachment plate is arranged at a (predefined) distance from the carrier plate and aligned with the latter. The surface of the first attachment plate is smaller than the surface of the carrier plate. The acoustic sensor is configured to detect a bullet penetration through the carrier plate or through the first attachment plate at a time offset from a bullet penetration through the first attachment plate or through the carrier plate.

[0013] The term "carrier disc" refers to the disc with the largest surface area, in front of and / or behind which the smaller attachment discs are arranged. The acoustic pickup is typically mounted on the carrier disc. The carrier disc is also usually connected to a tilting or pivoting mechanism, which tilts or pivots the carrier disc, along with the attachment discs, backward upon a hit. In principle, however, other hit feedback can also be provided, such as color-graduated (light) signals.

[0014] The term "mounting disc" refers to the smaller discs arranged at a defined distance in front of and / or behind the carrier disc. They are generally mounted in such a way that they can be replaced quickly and easily. A physical connection between the mounting discs and the carrier disc is generally not required. The mounting discs can also be arranged in front of or behind the carrier disc using a separate bracket.

[0015] In this case, “aligned” means that the first mounting disc does not substantially protrude beyond the edge of the (larger) carrier disc when viewed from the front.

[0016] The term “bullet penetration” refers to the moment at which, after firing a shot, the shooter’s bullet penetrates the respective partial disc of the target arrangement and thus triggers a sound pulse which is detected by the acoustic pickup.

[0017] With the target arrangement according to the invention, the target effect can be represented variably and situationally at different points of impact and the shooter can be given immediate feedback (i.e. in real time) in this regard, which ultimately results in a greatly improved training effect for the shooter.

[0018] The first mounting disc is connected to the carrier disc via two lateral connecting bars. For this purpose, the first mounting disc has side sections that protrude at right angles, which define the distance to the first partial disc. These are usually folded over again at their ends, creating fastening edges to which the first mounting disc is riveted or glued to the carrier disc. Other types of fastening devices are also conceivable, such as nails, thumbtacks, screws, and the like.

[0019] According to the invention, the target assembly further comprises a drive and evaluation unit and a mount for the carrier disc, the mount being tiltable about a rotational axis relative to the drive and evaluation unit. The drive and evaluation unit receives signals from the acoustic sensor indicating the number of bullet penetrations and can thus react to different hit positions by triggering the tilting or pivoting mechanism. The drive and evaluation unit is equipped with a corresponding motor for this purpose.

[0020] According to the invention, the drive and evaluation unit is configured such that, when a bullet passes through the carrier disc alone, the holder, together with the carrier disc and the first attachment disc, tilts backward approximately 45° and immediately subsequently re-erects it. This represents a hit position with a potentially lower target effect, i.e., a potentially non-lethal hit.

[0021] According to the invention, the drive and evaluation unit is configured such that, when a projectile passes through both the carrier disc and the first attachment disc, the mount, together with the carrier disc and the first attachment disc, tilts backward approximately 90° and, if necessary, re-erects it after a predefined period of time. Accordingly, this represents a hit location with a potentially high or maximum target effect, i.e., a potentially lethal hit.

[0022] Preferably, the first target is positioned in front of the carrier target in the direction of fire. This allows the chest and / or head area of ​​an enemy to be simulated, for example, on an army rifle target. A bullet penetrating both the first target and the carrier target would result in a potentially lethal hit and thus the highest target effectiveness. In this case, particular emphasis is placed on a bullet entering the chest and / or head area of ​​the enemy. However, the first target or another target can also be positioned behind the carrier target in the direction of fire to improve target analysis with regard to the potential trajectory of the bullet through the body.

[0023] Preferably, the first mounting disc is arranged substantially parallel to the carrier disc. This type of arrangement is preferred for reliable detection of the sound pulses.

[0024] Preferably, the first attachment disc is arranged at a distance of approximately 1 cm to approximately 10 cm, preferably approximately 2.5 cm to approximately 7.5 cm, more preferably approximately 3.5 cm to approximately 5.5 cm, and even more preferably approximately 4 cm to approximately 5 cm from the carrier disc. Within these distance ranges, it can be ensured that the sound pulses generated when a bullet penetrates the carrier disc and the first attachment disc can be separated or detected as separate pulses by a standard sound sensor, since the time difference between the bullet penetrations is sufficiently large within these distance ranges.

[0025] Preferably, the acoustic pickup is a sound sensor. This design enables particularly simple and cost-effective production. However, the acoustic pickup can also be designed in the form of a suitable microphone device.

[0026] Preferably, the acoustic pickup is arranged on the carrier disc, preferably at its lower end. This allows for particularly reliable detection of the sound pulses generated by the bullet penetration.

[0027] Preferably, the first mounting disc is color-matched to the carrier disc. This way, the first mounting disc is not visually detectable—especially if it is positioned in front of the carrier disc in the direction of fire—and thus does not act as an unwanted aiming aid.

[0028] The target assembly preferably has a second mounting disc, which is preferably arranged opposite the first mounting disc on the carrier disc. By using several successively arranged target surfaces, which can be positioned in front of and / or behind the first carrier disc in the direction of fire, the target evaluation can be continuously improved, as already mentioned above.

[0029] When using a second and possibly additional mounting disc, the drive and evaluation unit can be configured so that upon three (or more) bullet penetrations, the mount, together with the first and second partial discs, tilts backward approximately 90° and then remains tilted for correspondingly longer periods (e.g., compared to a hit with two bullet penetrations). In principle, a different hit feedback can also be provided than a tilt or swivel function, e.g., via colored (light) signals.

[0030] Preferably, the surface of the second mounting disc is smaller than the surface of the first mounting disc. This allows for a particularly high target effect with a correspondingly precise shot.

[0031] The target arrangement according to the invention can be used equally for stationary and mobile targets or shooting targets.
