Description

Shot evaluation device and firearm

[0001] The invention relates to a shot evaluation device for a firearm and to a firearm having a shot evaluation device. The firearm is, in particular, a handgun. The handgun can be a long gun or a short gun, for example, a rifle or a pistol. In particular, it is a self-loading firearm or a semi-automatic or fully automatic firearm. The firearm can also be a repeating weapon or a single-shot weapon.

[0002] EP 4 050 297 A1 discloses a firearm analysis device comprising a coil arranged on the grip of a pistol. Oppositely polarized permanent magnets are arranged on a slide and can move together with the slide relative to the grip and the coil. An even number of oppositely polarized magnets is required. During such a movement, a voltage can be induced in the coil. Due to the differently polarized magnets, the voltage also changes its polarity, depending on which of the two magnets is used to induce the voltage in the coil. From this induced voltage, both a reference signal and a measurement signal are generated, which are compared with each other in order to identify characteristic points in time during the movement of the slide relative to the grip.

[0003] WO 2016 / 016744 A1 describes an electronic system for a firearm for detecting a shot. The system is installed in a mounting space of the weapon, for example in the grip area of ​​the stock, or mounted on the outside of the weapon.

[0004] US 2010 / 0031552 A1 describes a firearm in which a bolt is movably mounted on the frame. A magnet or a coil is arranged on the bolt, while the other component, consisting of the magnet and the coil, is arranged on the frame. This allows the magnet and coil to move relative to each other when the bolt moves relative to the frame.

[0005] The known firearm analysis device has the disadvantage that it requires multiple permanent magnets (an even number: 2, 4, 6, etc.). A sufficiently high voltage must be induced by the multiple magnets. The analysis is performed by distinguishing between the forward and reverse travel of the slide. The firearm analysis device is located partly in the slide and partly in the grip and is therefore sensitive to external influences, especially contamination.

[0006] WO 2009 / 156944 A1 and EP 2 291 602 B1 describe a device for counting shots from firearms. This device shows a generator unit which, with the aid of a permanent magnet and a coil, generates a measurement signal depending on the movement of the device or the firearm. This signal provides the energy for evaluation of the measurement signal by a processor unit. The processor unit, which is separate from the generator unit, analyzes the supplied measurement signal based on default values ​​for the supplied measurement signal and interprets these as relevant to the shot or not, and additionally estimates the energy released during the shot. This is then recorded in a memory. This device for counting shots proves to be very complex and not very robust and, moreover, not very meaningful.

[0007] WO 2021 / 063672 A1 describes an arrangement for a shock sensor that can also be used as a shot counter arrangement. The shock sensor features a cage in which a spherical permanent magnet is arranged in a guide tube, which is enclosed with the guide tube by a sensor coil and a positioning coil. If the permanent magnet is moved from its rest position defined by the positioning coil by an impact, the surrounding sensor coil generates an electrical signal that is identified as a shock. This shock sensor proves to be relatively unrobust, fragile, and inaccurate during installation.

[0008] US patents US 5406730 B1 and US 4001961 B1 disclose shot counters that use a combination of different sensors, such as acoustic sensors and acceleration sensors, to improve accuracy. These sensors prove to be complex and vulnerable.

[0009] Based on the known prior art, it can be considered the object of the present invention to provide a shot evaluation device for a firearm and in particular a handgun, which enables reliable and simple evaluation with, at the same time, improved assembly.

[0010] This object is achieved by a shot evaluation device having the features of patent claim 1. Furthermore, the object is achieved by a firearm having such a shot evaluation device.

[0011] The shot evaluation device according to the invention is designed for use or installation in a firearm, in particular a handgun. The handgun can be a long gun or a short gun. The firearm is, in particular, self-loading. It can be a fully automatic or a semi-automatic firearm, in particular a handgun.

[0012] The shot evaluation device has a support device. A measuring conductor arrangement and a main magnet are arranged on the support device. The measuring conductor arrangement and the main magnet are movable relative to one another in a longitudinal direction. Starting from an initial position between the main magnet and the measuring conductor arrangement, the relative movement can take place in the longitudinal direction at least in a first movement range that adjoins the initial position.

[0013] The main magnet is preferably a permanent magnet. It is sufficient for the main magnet to have one magnetic pole pair, i.e., a single north pole and a single south pole. Alternatively, main magnets with more than one pole pair can be used. The main magnet is, in particular, longitudinally polarized.

[0014] In the installed position of the shot evaluation device in the firearm, the longitudinal direction is aligned at least substantially parallel to the direction of fire or parallel to a direction in which a weapon part moving during the firing of the shot moves relative to another weapon part.

[0015] Also arranged on the support device is an evaluation unit that is electrically connected to the measuring conductor arrangement. The evaluation unit is configured to evaluate a measurement signal generated due to the relative movement between the main magnet and the measuring conductor arrangement.

[0016] The carrier device, the measuring conductor arrangement, the main magnet and the evaluation unit form a common assembly or structural unit. This assembly or structural unit can be designed to be arranged on any part of the firearm that experiences acceleration when a shot is fired. The assembly can preferably be arranged on the part of the firearm that moves when a shot is fired. The structural unit is arranged in a closed housing. The housing is designed with one or more walls to prevent unwanted penetration of substances, in particular dirt, from the outside. The housing can be made exclusively from walls or from a supporting structure with attached walls. By means of the housing, the shot evaluation device can be arranged particularly easily on the relevant part of the firearm or incorporated into it.

[0017] According to the invention, the shot evaluation device does not have any components arranged on different weapon parts that move relative to one another during firing. This makes it possible to design the entire shot evaluation device as an assembly or as a structural unit and to arrange it on the weapon part that moves during firing.

[0018] A single main magnet with one pole pair is sufficient for the invention.

[0019] The weapon part that moves relative to a grip or frame part of the firearm during firing can be, for example, a bolt or slide, or a weapon part that moves together with the bolt or slide. This weapon part can also be moved during other events, such as manually loading the firearm.

[0020] The inventive design significantly simplifies the installation of the shot evaluation device in the firearm. The entire shot evaluation device can, for example, be protected against contamination and other external influences by a covering (e.g., the closed housing). In addition to the protective function, the closed housing also provides increased stability and thus robustness of the shot evaluation device. The relative position between the main magnet and the measuring conductor arrangement is defined within the shot evaluation device and does not depend on the relative position of weapon components of the firearm. The flexibility in selecting the installation position of the shot evaluation device in the firearm is increased. For example, the shot evaluation device can be mounted on a weapon component that is moving during the firing of the shot or is subjected to acceleration (due to recoil) but is otherwise stationary (e.g.,handle or frame part).

[0021] The design according to the invention also offers a high level of security against manipulation, since the entire assembly is assigned to a single identifiable weapon part.

[0022] A preferred development of the shot evaluation device shows a housing which is filled with rigid filling material, in particular with a casting compound. By means of the rigid filling material, which is in particular pasty or waxy, it is possible on the one hand to protect the components of the assembly contained therein particularly well against disruptive external influences and on the other hand to achieve a particularly effective transmission of movements from the outside via the housing with the introduced filling material to the components, in particular to the movable main magnet, which is guided in particular in a cylindrical, tubular guide, as well as to the measuring ladder arrangement, which is in particular implemented as a coil. This makes it possible in particular to increase the measuring accuracy of the shot evaluation device.It has proven particularly effective when the filler material is inserted between the housing and the movable main magnet with its guide and measuring conductor or coil. Gaps in the filler material have proven to be relatively harmless in the area of ​​the evaluation unit.

[0023] A preferred development of the shot evaluation device features a housing having at least one filling opening for the filling material, in particular the casting compound, and at least one degassing opening. These two openings make it possible to create a stable connection between the housing and the assembly with the movable main magnet, thereby achieving a particularly high measurement quality and particularly meaningful results from the shot evaluation device.

[0024] For further preferred further training of the Shot evaluation device is this for mounting in or on a weapon part that is moved backward from a resting position, opposite to the firing direction. This positioning generates extremely strong amplitudes of the electrical measurement signal, which facilitates analysis without significantly compromising the robustness of the shot evaluation device with its closed housing, especially with its filling material.

[0025] In a further preferred development of the shot evaluation device, it is designed for attachment in or on an add-on part, a fastening for an add-on part, a stock and / or a shoulder rest. In particular, the shot evaluation device is arranged in or on an add-on part, such as a telescopic sight, or in or on a fastening of a telescopic sight. It is precisely this arrangement of the shot evaluation device that enables good, safe and permanent positioning without the risk of unwanted damage due to extreme acceleration values. It is precisely through measures to improve the signal quality according to the invention and the developments that this positioning is achieved without any significant loss of the informative value of the shot evaluation device.

[0026] Preferably, the measuring conductor arrangement is arranged immovably on the support device, while the main magnet is mounted on the support device so that it can move longitudinally. Additionally or alternatively, it would also be possible to mount the measuring conductor arrangement so that it can move longitudinally on the support device, wherein the main magnet can, for example, be arranged immovably on the support device in the closed housing.

[0027] The measuring conductor arrangement preferably has a or more electrical conductors, which in particular form at least one two-dimensional or at least one three-dimensional winding. The measuring conductor arrangement can be designed as a two-dimensional or three-dimensional coil. A three-dimensional, in particular cylindrical, coil is preferred for the measuring conductor arrangement. This type of coil in particular enables a high level of information for the shot evaluation device.

[0028] The measuring conductor arrangement is preferably designed as a coil, in particular a cylindrical coil. The coil surrounds a coil interior. A coil axis extending through the coil interior can be oriented longitudinally. The main magnet can engage at least partially in the coil interior and move, in particular, along the coil axis in the coil interior and / or through the coil interior.

[0029] It is also preferred if the measuring conductor arrangement is located within a magnetic field generated by the main magnet in every relative position between the measuring conductor arrangement and the main magnet. This allows a voltage to be induced in the measuring conductor arrangement in every relative position during a relative movement between the main magnet and the measuring conductor arrangement, and a measurement signal can be generated based thereon.

[0030] In a further preferred embodiment of the shot evaluation device, the coil has a length that is less than or equal to the length of the main magnet. This design makes it possible to reduce the installation space for the components and thus the assembly without limiting the electrical signal generated by induction from the main magnet in conjunction with the coil. This makes it possible to maintain the informative value of the shot evaluation device.

[0031] In a further preferred embodiment of the shot evaluation device, the coil interior is completely or largely filled when the main magnet is in a rest position. This arrangement, with the main magnet in the rest position within the coil interior, makes it possible to shape the generated electrical signal advantageously for further processing or subsequent evaluation, thereby increasing the informative value of the shot evaluation device.

[0032] In one embodiment, a stop can be provided on the carrier device. The stop and the carrier device are arranged immovably relative to one another. However, the stop can itself be elastically deformable under the forces occurring between the carrier device on the one hand and the main magnet or the measuring conductor arrangement on the other. The stop limits the first range of movement and can be provided to define the starting position, i.e. the relative position between the main magnet and the measuring conductor arrangement without external force, i.e., for example, the starting position before a shot is fired.

[0033] It may also be advantageous if, in the longitudinal direction, a first movement range is connected to one side of the starting position and a second movement range is connected to the other side. The main magnet and the measuring conductor arrangement can be arranged on the support device so that they can move relative to one another in the longitudinal direction, both in the first movement range and in the second movement range. In this embodiment, There is no mechanical limitation in the starting position that restricts the relative movement exclusively to the first range of motion in the longitudinal direction. For example, the main magnet can move from the starting position relative to the measuring conductor arrangement and relative to the carrier device both into the first range of motion and in the opposite direction into the second range of motion. This can improve the generation and evaluation of the measuring signal. This is because it is possible, for example, for the starting position to be passed through once or several times following the start of the relative movement between the main magnet and the measuring conductor arrangement.

[0034] The shot evaluation device preferably has a force generating device. The force generating device is configured to generate a force acting in the longitudinal direction between the main magnet and the measuring conductor arrangement. For example, the force generating device can be attached to the support device and apply a force to the main magnet or the measuring conductor arrangement, depending on whether the main magnet or the measuring conductor arrangement is mounted so as to be movable in the longitudinal direction relative to the support device.

[0035] The force between the main magnet and the measuring conductor arrangement can act from the starting position toward the first range of motion and / or toward the second range of motion. If two opposing forces are generated in the longitudinal direction, this can, for example, define the starting position, which in this case defines a rest position.

[0036] The force generating device can optionally push the main magnet and / or the measuring conductor arrangement against a stop into the starting position.

[0037] To generate the force acting in the longitudinal direction, the force generating device can have at least one elastically deformable body, e.g. a spring, in particular a helical spring, an elastically deformable elastomer body, etc. Additionally or alternatively, the force generating device can have at least one magnet to generate the force acting in the longitudinal direction. This is particularly advantageous if the main magnet is mounted so as to be movable in the longitudinal direction relative to the carrier device, so that the force generated by the force generating device can be achieved by magnetic repulsion and / or magnetic attraction between the at least one magnet of the force generating device and the main magnet.

[0038] In a preferred embodiment, the shot evaluation device is provided with a force generating device which has at least two elastically deformable bodies, in particular at least one spring element, or at least two magnets, which are designed to hold the main magnet in a rest position, in particular within the coil interior. The rest position lies on the intended movement path of the main magnet, which typically runs in the longitudinal direction of the shot evaluation device or the housing. By designing the shot evaluation device with this force generating device, it is possible to achieve an advantageous shape of the electrical signal of the measuring conductor arrangement designed as a coil, which enables a particularly reliable and meaningful evaluation or analysis in With regard to the shooting event.

[0039] In a preferred embodiment, the shot evaluation device is designed without batteries. In particular, the shot evaluation device does not have an energy storage device that provides a longer or permanent energy supply to the evaluation unit. This is to be understood, for example, as an energy storage device that is designed to provide an energy supply for a period of time that is longer than one or two times the time required to fire a shot (i.e. from the start of the movement of the moving weapon part from a rest position to the return to this rest position). In particular, the shot evaluation device does not have an energy storage device that provides an energy supply for longer than 100 milliseconds or longer than 50 milliseconds or longer than 20 milliseconds or longer than 15 milliseconds or longer than 10 milliseconds.

[0040] In one embodiment, the shot evaluation device is designed without a battery and without a buffer capacitor for buffering the electrical energy that is generated in the measuring conductor arrangement when the shot is fired.

[0041] It is preferred if the evaluation unit is operated exclusively by means of the electrical energy that is induced in the measuring conductor arrangement when a shot is fired.

[0042] It is advantageous if the evaluation unit is designed to generate the measuring signal based on an alternating signal which is applied to the measuring conductor arrangement when the measuring conductor arrangement and the main magnet move relative to each other, for example in the case of a When firing a shot, when manually loading the firearm or when subjected to an external impact (e.g. dropping the firearm).

[0043] The measurement signal can be an analog or a digital signal. In one embodiment, the alternating signal applied directly to the measuring conductor arrangement can be used as the measurement signal. In all embodiments, the alternating signal applied to the measuring conductor arrangement can be additionally or alternatively processed in another way to generate the measurement signal, for example, filtered and / or limited and / or transformed (e.g., using a voltage divider) to maintain a value range available for evaluation.

[0044] The evaluation unit is particularly configured to generate at least one piece of evaluation information based on the measurement signal and preferably to store this information in a memory of the evaluation unit. In a preferred embodiment, the memory is a non-volatile memory, e.g., EEPROM, a flash memory, a ferroelectric memory (FRAM or FeRAM), or the like.

[0045] It has proven particularly advantageous to design the evaluation unit in such a way that the supplied electrical measurement signal is rectified and, in particular, smoothed before evaluation. The rectified and, preferably, smoothed electrical signal proves to be significantly more meaningful than the original electrical signal and can thus be fed to a better and more meaningful evaluation or analysis by the further evaluation unit. This proves particularly within the framework of the adjusted threshold values ​​or within the framework of the classification of the course of the smoothed or rectified measurement signal as particularly relevant for increasing the meaningfulness and reliability of the evaluation of a shot event and thus for the shot evaluation device.

[0046] To generate the evaluation information, the evaluation unit can be configured to compare the measurement signal with at least one predetermined threshold value. In particular, at least one time window can be defined for the measurement signal, within which a value or magnitude of the measurement signal is compared with the respectively assigned, at least one threshold value.

[0047] The at least one time window and the at least one threshold value assigned to each time window can be specified to the evaluation unit and stored, for example, in memory. The at least one time window and / or the at least one threshold value can be empirically determined, for example, through tests or simulations or in some other way and specified to the evaluation unit.

[0048] The at least one time window and / or the at least one threshold value are preferably predetermined in such a fixed manner for the evaluation unit that they are not changed during subsequent operation after initialization of the shot evaluation device. Adjustment of the at least one time window and / or the at least one threshold value may be possible during a new initialization, for example, when weapon parts are replaced.

[0049] In principle, it is sufficient to define a single time window and assign a single threshold value to this time window. In order to improve the evaluation and the at least one piece of evaluation information determined thereby, a plurality of time windows, each with a single assigned threshold value, can be used. Optionally, one or more time windows can each be assigned a plurality of threshold values. In this way, for example, a more precise distinction can be made as to what triggered the relative movement between the measuring conductor arrangement and the main magnet. For example, it may be possible to distinguish between two or more of the following events: a manual reload, a shot with live ammunition of a certain ammunition type, a shot with practice ammunition, an external shock or impact on the firearm, etc.

[0050] A preferred development of the shot evaluation device shows an evaluation unit which is set up, based on the measurement signal, to differentiate between the acceleration in the longitudinal direction, forwards or backwards, and to generate the evaluation information in a differentiated manner depending on this. Through this differentiated analysis based on the different directions (forwards or backwards along the longitudinal direction) of the acceleration or movement of the main magnet relative to the coil or the measuring rod arrangement, it is possible to identify the quality of the assessment of the shot event even more precisely, which applies in particular by determining a successive forward and backward movement that is characteristic of a shot.

[0051] In general, the at least one piece of evaluation information may comprise one or more of the following information in any combination:

[0052] a total number of shots fired with the firearm,

[0053] a number of shots fired with the firearm using a specific type of ammunition, which may include a number for several usable types of ammunition,

[0054] information describing a firing frequency, for example a time period between two immediately consecutive shots, whereby statistical values ​​can also be determined here, such as a maximum firing frequency or an average firing frequency,

[0055] a recommendation for an action to be carried out on the firearm, for example a testing action, a maintenance action, a repair action, a cleaning action, etc.

[0056] In an advantageous embodiment of the shot evaluation device according to the invention, the evaluation unit can have at least one sensor, such as an acceleration sensor for measuring an acceleration in at least one spatial direction and / or a gyro sensor. Additionally or alternatively, a sensor can also be present which is assigned to an operating element and detects the movement of the operating element, such as a sensor detecting the movement of the trigger of the firearm. By means of the at least one sensor, at least one additional parameters are determined, and based on them, at least one further piece of evaluation information is generated. Any number of available parameters and / or data and / or information can be linked or related to one another in any way. For example, at least one piece of evaluation information can be generated that can contain one or more of the following information in any combination: • information on the movement of the firearm (speed and / or acceleration of the firearm), • an alignment of the firearm (e.g. using a gyro sensor), • information describing the movement of the trigger, • information describing the manual loading of the firearm, • a sight or target information, • information on the movement or alignment of the firearm during aiming, during firing, after firing, etc.

[0057] It is advantageous if the shot evaluation device has a communication device that is configured to establish a communication connection with an external terminal, such as a computer, a tablet, a smartphone, or any other suitable computing and / or data processing device. The communication connection between the communication nication device and the terminal device is produced in particular without contact, for example based on any known wireless communication connection or any known wireless communication standard, such as e.g. near-field communication (NFC), RFID communication connection, Bluetooth, WiFi, etc. Additionally or alternatively, a wired communication interface may also be present, such as e.g. a USB interface.

[0058] The energy supply during the reading or transmission of the at least one item of evaluation information from the evaluation unit to an external terminal device can be provided by the wireless and / or wired communication connection via electrical energy from the terminal device.

[0059] To communicate with the communication device of the evaluation unit, the terminal device may have a communication device or be communicatively connected to a separate, individual communication device. The terminal device or the communication device may be part of a weapon storage device (e.g., a weapon rack), so that when the firearm is placed on the weapon storage device or the weapon rack, a communication connection can be or is established—preferably automatically—from the terminal device or the external communication device to the communication device of the evaluation unit. Optionally, access to at least one piece of evaluation information can be made automatically, for example in order to update the data available in the terminal device.

[0060] In addition or alternatively to the terminal device, another suitable external device can also be used which has at least read out and / or store evaluation information and / or make it available in an application (app) by means of which a user can be provided with at least one piece of evaluation information in a suitable manner (e.g. graphically and / or in text form and / or acoustically and / or haptically).

[0061] A further embodiment of the invention features a firearm, particularly a handgun, which is provided with at least one shot evaluation device according to the invention. This integrated or attached shot evaluation device according to the invention makes it possible to reliably detect the number of shots and, at the same time, to enable a simple and robust construction for the firearm with the shot evaluation device.

[0062] A preferred development of the firearm shows at least one shot evaluation device which is fastened in or on an attachment, in particular a telescopic sight, or in or on the holder of the attachment, in particular the telescopic sight. It is precisely this positioning that enables secure, robust and therefore permanent positioning with high informative value of the shot evaluation device, particularly when, in addition to the closed housing, further measures are provided to increase the informative value or the quality of the informative value. It is precisely by analyzing the course of the signal to be analyzed, according to the type of course, in particular by classifying the signal course, that a reliable assessment and analysis with regard to the presence or absence of a shot can be made even in the case of a weak signal.

[0063] Another preferred development of the firearm shows at least one weapon part which moves when a shot is fired, in particular a bolt and / or slide which, when a shot is fired, is accelerated backwards from a rest position against the direction of fire and then moved back into its rest position. This development also shows at least one shot evaluation device which is arranged on or in the movable weapon part in such a way that it moves together with the movable weapon part. The strong acceleration due to the selected positioning of the at least one shot evaluation device makes it possible to obtain an electrical measurement signal with a large amplitude, which, especially when evaluated using threshold values, in particular in a certain defined time window, leads to a simple and reliable shot evaluation device for this firearm.

[0064] Advantageous embodiments of the invention emerge from the dependent claims, the drawings, and the description. Preferred embodiments of the invention are explained in detail below with reference to the accompanying drawings.

[0080] Figure 19 shows a cross section through the components of the shot evaluation device according to Figure 17 along section line XIX-XIX.

[0081] Figures 1 and 2 schematically illustrate a firearm 21 equipped with a shot evaluation device 20 according to the invention. The firearm 21 can, in particular, be a handgun, for example, a pistol 22. In the exemplary embodiment, the firearm 21 is self-loading and can be designed as a fully automatic or semi-automatic firearm 21. Deviating from the exemplary representation of the pistol 22, it can generally be either a long gun or a short gun, such as a rifle, a machine gun, or a submachine gun. The firearm 21 can alternatively also be a repeating weapon or a single-shot weapon.

[0082] The shot evaluation device 20 is in or on a weapon part that moves at least during the firing , which is referred to here as the movable weapon part 23. When a shot is fired from a rest position (Figure 1), the movable weapon part 23 is accelerated backwards (Figure 2) against the direction of fire, in particular by the recoil when the propellant charge of the cartridge is ignited. The movable weapon part 23 is then moved back into its rest position, for example by a return device which in particular has at least one return spring. The movable weapon part 23 can, for example, be a breech and / or slide 24 of the firearm 21. The shot evaluation device 20 is arranged on the movable weapon part 23 in such a way that it moves together with the movable weapon part 23.

[0083] The movable weapon part 23 and, for example, the slide 24 can optionally also be moved manually, for example for manually loading the firearm 21.

[0084] As can be seen from the schematic representation in Figure 2, the movable weapon part 23, formed for example by the slide 24, moves relative to a frame part or to a grip 25 of the firearm 21 or pistol 22 either during manual loading or when firing.

[0085] As an alternative to the illustrated embodiment, the shot evaluation device 20 can also be arranged on a weapon part which does not move relative to the frame part or the grip 25 when the shot is fired, for example in or on the frame part or grip 25.

[0086] Exemplary embodiments of the shot evaluation device 20 are illustrated in a highly schematic manner in the manner of a block diagram in Figures 3 to 8. The shot evaluation device 20 has a carrier device 29 on which a measuring conductor arrangement 30 is arranged. The measuring conductor arrangement 30 has at least one electrical conductor 31 which can form one or more turns. In the exemplary embodiment, the measuring conductor arrangement 30 is designed as a coil 32 with a plurality of turns. The coil 32 delimits a coil interior 33 which is enclosed by the turns of the coil 32 and has a defined length. The coil 32 can be wound in a screw shape or a helix shape.

[0087] In Figures 3 to 8, the support device 29 is illustrated only in a highly schematic manner. An exemplary embodiment of the support device 29 will be explained further below in connection with a preferred structural design with reference to Figures 15 to 19.

[0088] The carrier device 29 has an attachment part 34 to which the measuring conductor arrangement 30 with the at least one electrical conductor 31 and, for example, the coil 32 is attached. The attachment part 34 is hollow and cylindrical in the exemplary embodiment. An outer wall of the attachment part 34 serves to arrange the coil 32. The attachment part 34 thus extends directly inward along the coil 32 through the coil interior 33. In the coil interior 33 and, for example, in a receiving space 35 of the attachment part 34, a main magnet 36 is mounted in a longitudinal direction L relative to the attachment part 34. Thus, in the longitudinal direction L, a relative movement between the measuring conductor arrangement 30 and, for example, the coil 32 and the main magnet 36 .

[0089] In the exemplary embodiment, the main magnet 36 has a pole pair, namely a single magnetic north pole N and a single magnetic south pole S (Figures 10, 11). The main magnet 36 is a permanent magnet that is magnetized in the longitudinal direction L. The shape of the main magnet 36 is rotationally symmetrical about an axis extending parallel to the longitudinal direction, for example, cylindrical at least in sections, in particular circularly cylindrical. The main magnet 36 has a defined length.

[0090] 3 to 6, the length of the main magnet 36 corresponds to the length of the coil 32 and thus of the coil interior 33. In contrast, in Figures 7 to 8, the length of the main magnet 36 is selected to be greater than the length of the coil 32 and thus of the coil interior 33. In both cases, the main magnet 36 can therefore fill the coil interior 33. This situation is preferably referred to as rest or The equilibrium position selected for the main magnet 36 results in a very well-evaluated and meaningful measurement signal that can be evaluated with the aid of the evaluation unit 40.

[0091] In a modified embodiment, it would alternatively be possible for the main magnet 36 to be arranged longitudinally direction L is arranged immovably on the support device 29 and the measuring conductor arrangement 30 or the coil 32 is mounted so as to be movable relative thereto in the longitudinal direction L. It is essential that a relative movement in the longitudinal direction L can take place between the main magnet 36 and the measuring conductor arrangement 30 or the coil 32.

[0092] The shot evaluation device 20 also has an evaluation unit 40. The evaluation unit 40 is communicatively connected to the measuring conductor arrangement 30 and, for example, to the coil 32 and, in the exemplary embodiment, is electrically connected via conductors. An electrical variable present at the measuring conductor arrangement 30 or the coil 32 can be transmitted to the evaluation unit 40. This electrical variable is, in particular, an electrical voltage or an electrical current. In the exemplary embodiment, an alternating electrical signal W can be generated at the coil 32 during operation and is made available to the evaluation unit 40. In this case, the alternating signal W is an alternating electrical voltage UW that is induced in the coil 32 during a relative movement between the main magnet 36 and the coil 32.

[0093] A block diagram of the evaluation unit 40 is shown in Figure 12. In the exemplary embodiment, the alternating signal W forms an electrical measurement signal M, which can be evaluated by the evaluation unit 40. Alternatively, the alternating signal could be preprocessed to form the measurement signal, for example, filtered, adapted to a value range, limited, scaled and / or transformed. The evaluation unit 40 can have a computing unit 41, for example a microcontroller, by means of which the measurement signal M and, in the exemplary embodiment, the alternating signal W or the alternating voltage UW are evaluated. can be .

[0094] In addition to the computing unit 41, the evaluation unit 40 in the exemplary embodiment has a non-volatile memory 42 and a communication device 43. The memory 42 and the communication device 43 are communicatively connected to the computing unit 41. Data or information can be stored in the memory 42, for example an evaluation result or evaluation information E, which the evaluation unit 40 or the computing unit 41 determines based on the measurement signal M. Parameters that the computing unit 41 can take into account during the evaluation, such as at least one threshold value C and / or a time window P for the evaluation of the measurement signal M.

[0095] The communication device 43 is configured to establish a communication connection to an external terminal 44. The external terminal 44 may, for example, be a mobile terminal 45, such as a tablet or a smartphone. The terminal 44 may also be any other computing and / or storage device 46, for example a non-portable computer, a server, an internet service (cloud service), or the like. The terminal 44 may additionally or alternatively be an attachment and / or aiming device, for example aiming optics and / or AR glasses ("AR" is the abbreviation for "Augmented Reality") and / or a night vision device, etc. This computing and / or storage device 46 may be communicatively connected to an external communication device 47, wherein the communication connection may be implemented wired or wirelessly. The external com- Communication device 47 can be arranged in or on a weapon storage body 48. The weapon storage body 48 can be a component of a gun cabinet or gun holder (Figure 12).

[0096] The evaluation unit 40 can optionally contain further components, such as at least one further sensor 50. The sensor 50 can, for example, be an acceleration sensor, a gyro sensor, a position sensor, a clock or any other suitable sensor by means of which at least one additional parameter can be detected, such as an orientation of the shot evaluation device 20 relative to a horizontal and / or vertical, at least one acceleration in at least one spatial direction, a temperature, a geographical position (based on position information from network signals, telecommunication signals, satellite signals, etc.), a time of day, for example in order to determine the time of the event (in particular the firing of the shot).

[0097] Figure 12 shows only one optional sensor 50 as an example. The number and type of such optional sensors 50 may vary, and more than one additional sensor 50 may be present.

[0098] The communication connection between the terminal 44 and the communication device 43 may be based on any known wireless communication principle, for example NEC, REID, WiFi, Bluetooth Low Energy, or the like. Additionally or alternatively, the communication connection between the terminal device 44 and the communication device 43 can also be wired. For this purpose, the communication device 43 can, for example, provide an interface, e.g., of the USB or USB-C type or another preferably standardized interface. Once the communication connection is established, the evaluation unit 40 is supplied with electrical energy via the communication connection.

[0099] The shot evaluation device 20 is preferably designed without a battery. The electrical energy required by the evaluation unit 40 is provided, in the preferred embodiment, by the alternating voltage UW induced in the measuring conductor arrangement 30 or the coil 32.

[0100] The induced alternating voltage UW can be provided in one embodiment of a supply unit 51. The supply unit 51 is optional. The supply unit 51 can have a rectifier 52 for rectifying the alternating voltage UW. The rectifier 52 can be constructed from active or passive elements and is preferably formed by a diode rectifier with exclusively passive components. The rectifier 52 has no controlled semiconductor switches. It can be designed as a half-bridge rectifier or full-bridge rectifier. As a further option, the rectified supply voltage UV can be smoothed and / or buffered by means of a capacitor 53.

[0101] In addition or alternatively to the supply unit 51, the supply voltage UV can also be provided by an optional existing battery 54 , in particular an inductively rechargeable battery , can be provided .

[0102] It should be pointed out again at this point that both the supply unit 51 and the battery 54 are merely optional components of exemplary embodiments, with the evaluation unit 40 preferably being designed without a battery.

[0103] Returning to the shot evaluation device 20 according to Figures 3 to 8, the shot evaluation device 20 preferably has a force generating device 60 which is designed to generate a force F between the main magnet 36 and the measuring conductor arrangement 30 and, for example, the coil 32 in the longitudinal direction L. In Figures 3 to 8, the force generating device 60 is only illustrated very schematically. The force generating device 60 is arranged on the carrier device 29 and generates the force F on the main magnet 36 by mechanical means and / or magnetically. The force F in the longitudinal direction L defines a starting position A0 between the main magnet 36 and the measuring conductor arrangement 30 or the coil 32 when the movable weapon part 23 (for example the bolt or slide 24) is in its rest position.

[0104] Starting from the starting position A0, a relative movement between the main magnet 36 and the measuring conductor arrangement 30 or the coil 32 can take place at least in a first movement range RI parallel to the longitudinal direction L, which adjoins the starting position A0 on one side. In the embodiment according to Figures 3 to 6, a movement starting from the starting position A0 into a first movement range RI which adjoins the first The second movement range R2 following the movement range RI is prevented by a stop 61. In the starting position AO, the main magnet 36 rests against the stop 61 and can only move relative to the measuring conductor arrangement 30 or the coil 32 from the starting position AO into the first movement range RI. The stop 61 is arranged on the carrier device 29 and, for example, the attachment part 34. The force F of the force generating device 60 urges the main magnet 36 in the exemplary embodiment in the direction of the stop 61, i.e. into the starting position AO.

[0105] The operation of the exemplary embodiment of the shot evaluation device 20 is explained with reference to Figures 3 to 6. When the movable weapon part 23 is accelerated in the longitudinal direction L by firing a shot or during manual reloading, the shot evaluation device 20 as a whole is also accelerated in the longitudinal direction L. In the exemplary embodiment according to Figures 3 to 6, the force F of the force generating device 60 acts parallel to the longitudinal direction L, opposite to the firing direction, i.e., to the rear. The stop 61 is arranged behind the main magnet 36.

[0106] By accelerating the movable weapon part 23 backwards against the firing direction, the entire shot evaluation device 20 is also accelerated backwards. The carrier device 29 with the measuring conductor arrangement 30 or the coil 32 and the evaluation unit 40 are fastened to the movable weapon part 23 (e.g., slide 24) in such a way that they move backwards together with the weapon part 23 (Figure 4). Due to the inertia of the main magnet 36, a rela- A positive movement takes place between the main magnet 36 and the measuring conductor arrangement 30 or the coil 32. The main magnet 36 moves away from the stop 61 against the force F of the force generating device 60. The relative movement of the main magnet 36 with respect to the measuring conductor arrangement 30 or the coil 32 induces a voltage in the measuring conductor arrangement 30 or the coil 32.

[0107] The movable weapon part 23 is accelerated backwards against a restoring force which is generated by a restoring device (not shown) of the firearm 21. After the movable weapon part 23 has reached its rearward position, it reverses its direction of movement due to the restoring force and moves forwards parallel to the longitudinal direction L, i.e. in the firing direction. As a result, the carrier device 29 with the measuring conductor arrangement 30 or the coil 32 and the evaluation unit 40 together with the weapon part 23 also reverse their direction of movement and move forwards. Due to this movement and the force F of the force generating device 60, a relative movement is brought about between the main magnet 36 and the measuring conductor arrangement 30 or the coil 32 back to the starting position A0, as shown schematically in Figure 5.

[0108] Finally, the measuring conductor arrangement 30 or the coil 32 and the main magnet 36 return to their original position corresponding to the starting position A0 ( Figure 6 ).

[0109] In Figures 7 and 8, analogous to the representation in Figures 3 to 6, another embodiment of the Shot evaluation device 20 is very schematic The main difference compared to the embodiment shown in Figures 3 to 6 is that in the modified embodiment shown in Figures 7 to 8 there is no stop and a relative movement between the main magnet 36 and the measuring conductor arrangement 30 or the coil 32, starting from the starting position AO, is possible both in the longitudinal direction L towards the front (first movement range RI) and towards the rear (second movement range R2).

[0110] 7 and 8, a force generating device 60 is provided which, by means of the generated force F, urges the main magnet 36 relative to the measuring conductor arrangement 30 or the coil 32 into the starting position A0. For this purpose, a force generating device 60 is provided, for example, which generates a force F with opposing force components Fl, F2. The two force components Fl, F2 are oriented opposite one another and parallel to the longitudinal direction L and urge the main magnet 36 relative to the measuring conductor arrangement 30 or the coil 32 into the starting position A0. For example, the first force component Fl is directed rearward in the longitudinal direction L and the second force component F2 is directed forward in the longitudinal direction L. The main magnet 36 and the measuring conductor arrangement 30 or the coil 32 are in force equilibrium between the two force components Fl, F2.Coil 32 relative to each other in the starting position A0. From this starting position A0, the main magnet 36 can move relative to the measuring conductor arrangement 30 or the coil 32 against the first force component Fl into the first movement range RI or against the second force component F2 into the second movement range R2. Figure 7 shows the starting position A0. Figure 8 shows an example of a deflection into the second range of motion R2.

[0111] The embodiment according to Figures 7 and 8 has the advantage that the induced alternating voltage signal UW in the measuring conductor arrangement 30 or the coil 32 can assume a larger difference between a positive voltage maximum and a negative voltage minimum due to the additional second movement range R2.

[0112] 10 and 11 show highly schematic exemplary embodiments of a force generating device 60. The length of the main magnets 36 and the length of the associated coils 32 and thus the associated coil interiors 33 are almost the same length, in particular slightly longer (in particular less than 10% longer). The force F or the force components Fl, F2 are generated mechanically in the exemplary embodiment according to Figure 10 by spring elements which are supported on the one hand on the carrier device 29 or the attachment part 34 and on the other hand on the main magnet 36. The spring elements 62 can, for example, each comprise a helical spring or any other suitable spring. Instead of spring elements 62, other elastically deformable bodies can also be used which generate a force F or force component Fl, F2 when deflected from the starting position A0.

[0113] In a modification of the embodiment according to Figure 10, in the embodiment according to Figure 11, the force F and, for example, the first force component F1 and the second force component F2 are generated contactlessly by magnets 63 of the force generating device 60. The magnets 63 of the force generating device 60 are arranged in the longitudinal direction L arranged on opposite sides of the main magnet 36. The magnetic poles are aligned such that the main magnet 36 is repelled by both magnets 63 of the force generating device 60. A north pole N of the magnet 63 is therefore arranged adjacent to the north pole N of the main magnet 36 and, analogously, a south pole S of the other magnet 63 of the force generating device 60 is arranged adjacent to the south pole S of the main magnet 36. With this arrangement, oppositely directed force components F1, F2 are generated, analogous to the spring elements 62 from Figure 10.

[0114] Figure 13 illustrates an exemplary embodiment of a method which can be referred to as the first method VI. In a first method step VII of the first method VI, the measurement signal M is generated because, due to a movement of the movable weapon part 23 (here slide 24), the main magnet 36 and the measuring conductor arrangement 30 (here coil 32) move relative to one another in the longitudinal direction L. This relative movement leads to an alternating signal W and, for example, an alternating voltage UW being induced as the measurement signal M, as is schematically illustrated by way of example in Figure 9.

[0115] At a starting time tO, the relative movement between the main magnet 36 and the measuring conductor arrangement 30 or the coil 32 begins, whereby the measuring signal M is induced in the form of the alternating voltage UW. As can be seen schematically in Figure 9, due to the inertia of the main magnet 36, the measuring conductor arrangement 30 or the coil 32 begins to move backwards together with the movable weapon part 23 in the longitudinal direction L. The voltage generated in the coil 32 has a first polarity, for example a positive polarity . When the main magnet 36 overcomes its inertia and the movement of the movable weapon part 23 is slowed down (e.g. by a locking spring or another component of the firearm 21 ), the alternating voltage UW reaches a first extreme point (here: local maximum) at the first time t1 and begins to fall after the first time t1. Following this, the generated alternating voltage UW crosses zero at a second time t2. The polarity of the generated alternating voltage UW is reversed . This is also due to the fact that the relative movement between the main magnet 36 and the measuring conductor arrangement 30 or .the coil 32 is reversed, among other things because the movable weapon part 23 reverses its direction of movement at the second time t2 and moves forward again in the longitudinal direction L, but in particular due to the elimination of the force F or the reversal of the force F generated by the force generating device 60 (e.g. magnetic force). This causes the movement back towards the starting position AO. The polarity of the generated alternating voltage UW is reversed and becomes negative, for example.

[0116] In a subsequent second method step V12 of the first method VI, the measurement signal is evaluated. For this purpose, it is compared, for example, with at least one threshold value C. The comparison with the at least one threshold value C takes place in a defined time window P, while the measurement signal M and, for example, the alternating voltage UW are present. The time window P is preferably offset in time from a start time t0.

[0117] From the start time tO, electrical energy is made available to operate the evaluation unit 40 due to the induced alternating voltage UW. At a time interval from the start time tO, for example after the first time t1 or preferably after the second time t2, sufficient electrical energy has been generated to wake the evaluation unit 40 from a rest or sleep state and bring it into an operational state. Only then can the induced alternating voltage UW, which here forms the measurement signal M, be evaluated by means of the evaluation unit 40. For this reason, the at least one time window P, in which an assigned threshold value C is evaluated, is defined at a sufficient time interval from the start time tO and, for example, after the second time t2.This means that the alternating voltage signal UW, which has a negative polarity after the second time t2, is compared in the present case with an assigned negative threshold value, which is entered in Figure 9 as the first threshold value CI. The assigned time window P is the first time window PI, in which the threshold value comparison with the first threshold value CI takes place. If the magnitude of the measurement signal M or of the alternating voltage signal UW exceeds the magnitude of the assigned threshold value (branch OK from the second method step V12 in Figure 13), a shot is detected, for example, and a shot counter is incremented in a third method step V13 of the first method VI. After that, or if no threshold value has been detected (branch NOK from the second method step V12), the method starts again from the beginning and the system waits for the next measurement signal M to be generated.

[0118] Figure 14 shows a modified exemplary embodiment of a method which is referred to as the second method V2. In the second method V2, two or more time windows P are defined, within each of which a comparison of the generated measurement signal M with an assigned threshold value C is carried out. For example, in addition to the first time window P1, a second time window P2 is defined, to which a second threshold value C2 is assigned (Figure 9). The second time window P2 is defined, for example, after a third time t3, at which the measurement signal M and, for example, the alternating voltage UW have a further zero crossing. At the third time t3, the measurement signal M or the alternating voltage UW changes polarity again and becomes positive again in the exemplary embodiment.This positive half-wave following the third time t3 arises in particular in embodiments of the shot evaluation device 20 in which the main magnet 36 and the measuring conductor arrangement 30 or the coil 32 can move both forwards and backwards parallel to the longitudinal direction L without the presence of a stop from the starting position AO, i.e. in the first movement range RI and in the second movement range R2 starting from the starting position AO. Due to the inertia of the main magnet 36, when moving forwards it moves through its rest position assigned to the starting position AO (third time t3). Following the third time t3, the second time window P2 is defined, to which the second threshold value C2 is assigned. Here too, the magnitude of the measuring signal M or the alternating voltage UW is compared with the magnitude of the threshold value C2 within the second time window P2.

[0119] As can be seen in Figure 14, the first method step V21 and the second method step V22 of the second method V2 correspond to the first two method steps of the first method VI. If it is detected in the second method step V22 that the magnitude of the measurement signal M exceeds the magnitude of the first threshold value CI (because of the negative polarity, the measurement signal M falls below the negative first threshold value CI in this case), the second method V2 is continued in a third method step V23, in which the magnitude of the measurement signal M is subsequently compared with the magnitude of the assigned second threshold value C2 during the second time window P2.If the magnitude of the measurement signal M exceeds the magnitude of the second threshold value C2 during the second time window P2 (branch OK from the third method step V23), a shot is detected and the shot counter is incremented in a fourth method step V24 of the second method V2. Otherwise. (Branch NOK from the third process step V23), the process can be continued with the first process step V21. Optionally, in a fifth process step V25, a counter can be incremented to indicate that another event has occurred. For example, in this way, a shot can be fired with different ammunition types or a manual reloading can be differentiated by defining appropriate threshold values.

[0120] If in the second method step V22 the amount of the first threshold value CI is not exceeded by the amount of the measuring signal M and also after the fourth method step V24 , the second method V2 starts again with the first method step V21 and the Generation of a new measurement signal M waited .

[0121] It is understood that the second method V2 shown in Figure 14 can be further modified. The number of defined time windows and threshold values ​​as well as the number of threshold values ​​per time window can vary. For example, within a defined time window P it can also be compared whether the magnitude of the measurement signal M exceeds a lower threshold value but remains below an upper threshold value. Depending on the number of defined threshold values, two, three or more different events can thus be differentiated from one another, for example the manual reloading of the firearm 21, a shot being fired with a first type of ammunition (e.g. live ammunition), a shot being fired with a second type of ammunition (e.g. ammunition with a rubber projectile, blank cartridge, practice ammunition with or without a projectile, practice ammunition with a color marking projectile), etc.Even different ammunition loads of different types of live ammunition can be distinguished from one another in this way, provided that the firearm 21 can fire different types of live ammunition. The number of distinguishable ammunition types can also be greater than two.

[0122] The number of shots fired, for example, represents an evaluation result or evaluation information E, which is determined by the evaluation unit 40. The evaluation information E can be stored in the non-volatile memory 42 of the evaluation unit 40 (Figure 12). Parameters required for the evaluation, such as the at least one threshold value C and / or information for characterizing the at least one time window P, can also be stored in the memory 42. and be made available to the computing unit 41 of the evaluation unit 40 for evaluation.

[0123] The availability of the evaluation unit 40, during which sufficient electrical energy is available for its operation, is limited in the preferred battery-free embodiment of the evaluation unit 40 and in particular shorter than the duration of a shot being fired. The duration of a shot being fired here is in particular the time required by the movable weapon part 23 to be moved backwards from the starting position and back forwards to the starting position. For example, a shot being fired can be approximately 40 to 50 milliseconds. The availability period of the evaluation unit can be a maximum of 30 milliseconds, a maximum of 20 milliseconds or a maximum of 15 milliseconds without a battery or capacitor. In the exemplary embodiment, the availability period is in the range of approximately 10 milliseconds when a shot is fired with live ammunition using the pistol 22.However, the availability period may depend on the acceleration of the moving weapon component, as well as the mass of the moving parts of the firearm and the shot evaluation device 20. Therefore, the availability period of the evaluation unit will also vary depending on the weapon type and the ammunition type. However, the availability period without storing electrical energy in a battery or capacitor is significantly shorter than the firing period during a single shot.

[0124] In addition or alternatively to counting the number of shots fired - possibly subdivided and assigned to specific ammunition types - the evaluation information E can also include, for example, a firing frequency or information correlating therewith by the evaluation unit 40 and stored in the memory 42. For this purpose, it may be necessary for the evaluation unit 40 to have a clock, an oscillator or another device for time measurement or time referencing (for example, time referencing by means of a discharge characteristic of a capacitor) in order to record time information between two consecutive shots.

[0125] Additionally or alternatively, a measure to be carried out on the firearm 21 can also be determined as evaluation information and stored in the memory 42. For example, typical or characteristic curves of the measurement signal M or characteristic parameters of the measurement signal M can be known and stored, for example, in the memory 42. A characteristic temporal curve and / or at least one characteristic parameter can then be compared with the currently determined measurement signal M and, on the basis of the comparison, a measure to be carried out, if necessary, can be stored in the memory 42. A characteristic parameter of the measurement signal M can, for example, be the time duration between two immediately successive zero crossings and / or the amplitude of one or more half-waves of the measurement signal M orof the alternating voltage UW and / or at least an absolute value of an extreme point (local maximum with positive polarity or local minimum with negative polarity). For example, if the amplitude of the alternating voltage UW decreases due to lower accelerations of the movable weapon part 23, increased friction may be present in the firearm 21, and an inspection of the firearm may be initiated.

[0126] The at least one time window P is preferred defined with a time interval from the zero crossings of the alternating voltage UW. A time window P is thus assigned either to a negative half-wave or a positive half-wave of the measurement signal M or the alternating voltage UW. It has been shown that this makes it possible to avoid external influences and any signal interference in the measurement signal M when parts of the shot evaluation device 20 or the firearm 21 that are moved during the firing of the shot change direction. Due to the availability period of the evaluation unit 40, a time window P (here: first time window P1 and second time window P2) is assigned to each of the second half-wave and / or the third half-wave of the alternating voltage signal UW, for example. During the first half-wave, for example, no evaluation takes place because the evaluation unit is not yet ready for use when the measurement signal M is generated.The evaluation of two half-waves (here: second half-wave and third half-wave) is sufficient. Optionally, one or more additional half-waves can also be included in the evaluation, but taking into account the maximum available availability period of the evaluation unit 40. Since the amplitude also decreases significantly after the third half-wave or after the fourth half-wave of the alternating voltage signal UW, an evaluation of the second half-wave and the third half-wave is more meaningful and sufficient.

[0127] Additionally or alternatively, a note can also be stored as evaluation information E when a predetermined number of shots is reached and this requires a specific maintenance measure or inspection measure or replacement measure of one or more components of the firearm 21, such as, for example, checking the barrel when a predetermined total number of shots is reached or similar.

[0128] Optionally, immutable information about the firearm 21 can also be stored in the memory 42, such as a weapon number, the manufacturer of the weapon, a serial number of one or more installed weapon components, such as the shot evaluation device 20 and / or an essential component of the weapon according to weapons law, date of manufacture, time of manufacture, place of manufacture, etc.

[0129] The information stored in memory 42 can be read out by means of the terminal device 44 and the establishment of a communication connection with the evaluation unit 40 or the communication device 43. Optionally, information can also be stored in memory 42 via the mobile terminal device 44. The energy required for this is provided to the evaluation unit 40 via the communication connection, for example, via near-field communication (e.g., NEC, REID), with energy being provided to the evaluation unit 40 inductively.

[0130] Figures 15 to 19 illustrate a design example for the implementation of a shot evaluation device 20 according to any of the above embodiments, in particular for the design of the support device 29. As explained, the measuring conductor arrangement 30 and, for example, coil 32, the evaluation unit 40, the main magnet 36, and, for example, the force generating device 60 are arranged on the support device 29. This assembly is arranged in a housing 65 of the shot evaluation device 20, which is illustrated in Figures 15 and 16. Figure 16 is a longitudinal section through the shot evaluation device 20 according to section line XVI-XVI in Figure 15. The housing 65 surrounds the support device 29 and the components arranged thereon. the shot evaluation device 20 completely. The housing 65 can, for example, be releasably or preferably non-releasably fastened in a recess on a weapon part of the firearm 21 (for example on the movable weapon part 23 of the firearm 21), e.g. by a screw connection and / or an adhesive connection and / or a potting compound.

[0131] The housing 65 can be constructed in several parts. In the exemplary embodiment, the housing 65 consists of a housing body 66 providing a housing interior, wherein the housing interior is accessible via a housing opening. The housing opening is located, for example, in the longitudinal direction L at one end of the housing body 66. The housing opening is closed by a housing cover 67. In the exemplary embodiment, the housing 65 has a cuboid contour. This simplifies installation or casting into the movable weapon part 23.

[0132] The structure of the carrier device 29 can be seen in particular in Figures 17 to 19. The carrier device 29 has a first section, on which the components required for signal generation of the measurement signal M are arranged, as well as a second section adjoining it in the longitudinal direction L, on which the components of the evaluation unit 40 are arranged. The attachment part 34 of the carrier device 29 is located in the first section. The second section is designed, for example, as a circuit board holder 68 for one or more circuit boards 69. The circuit boards 69 can, for example, be fastened to the circuit board holder 68 in a form-fitting and / or force-fitting and / or material-fitting manner and / or by an adhesive connection. For example, the circuit board holder 68 provides two end faces 70 arranged at a distance in the longitudinal direction L and facing one another, between which the at least one printed circuit board 69 can be arranged. The end faces 70 can be divided into stepped surface sections, which are preferably aligned at right angles to the longitudinal direction L and against which the edges of the at least one printed circuit board 69 can rest.

[0133] The circuit board holder 68 is followed by a transition section 74 with a first holding recess 75. The first holding recess 75 is designed to receive one of the two magnets 63 of the force generating device 60 and to hold it, for example, in a clamped manner on the carrier device 29. The first holding recess 75 is accessible from the outside in order to be able to insert the magnet 63 (Figures 17 to 19). For this purpose, a plurality of clamping webs can be provided on the transition section 74, which project into the holding recess 75 and against which the magnet 63 rests when inserted. The clamping webs can, for example, extend parallel to one another on sides of the first holding recess 75 that are opposite one another in the longitudinal direction L. The first holding recess 75 is preferably open at right angles to the longitudinal direction L, so that the magnet 63 can be inserted into the first holding recess 75 substantially at right angles to the longitudinal direction L.

[0134] The transition section 74 is adjoined by the attachment part 34 of the support device 29. As already explained, the attachment part 34 defines a receiving space 35 on the inside for arranging the main magnet 36. An outer surface of the attachment part 34 serves for arranging the measuring conductor arrangement 30 and, for example, for winding turns of the coil 32 around it.

[0135] It should be noted at this point that, in a modification of the preferred embodiment, the The measuring conductor arrangement 30 can also be formed not by a cylindrical coil 32, but by at least one electrical conductor 31 arranged or laid in a different way. For example, an electrical conductor 31 could run in sections essentially in the longitudinal direction L and in sections transversely to the longitudinal direction L, for example in a circumferential direction around the attachment part 34. The electrical conductor 31 does not have to completely enclose the attachment part 34 in the circumferential direction. The specific arrangements of the at least one electrical conductor 31 can vary. It is important that the at least one electrical conductor 31 of the measuring conductor arrangement 30 is located within the magnetic field of the main magnet 36 at least in phases when the shot evaluation device 20 is in use, so that a voltage can be induced by a relative movement.

[0136] On the side opposite the transition section 74 in the longitudinal direction L, an end section 76 of the carrier device 29 adjoins the attachment part 34. The end section 76 can be connected to the attachment part 34 in a force-fitting and / or form-fitting and / or material-fitting manner and / or by an adhesive connection. For example, the end section is designed in the manner of a cup or a cap and has a hollow cylindrical part 77. This hollow cylindrical part 77 can enclose an axial end region of the attachment part 34 on the outside, or the axial end region of the attachment part 34 can enclose the hollow cylindrical part of the end section 76. A threaded connection, a locking connection, or an adhesive connection can be produced.

[0137] The hollow cylindrical part 77 is followed by an end piece 78 with a second holding recess 79. The second holding recess 79 is configured to receive the respective other magnet 63 of the force-generating device 60. For this purpose, a plurality of clamping webs can protrude into the second holding recess 79, similar to the first holding recess 75. The clamping webs can be arranged distributed in a circumferential direction around the longitudinal direction L. The second holding recess 79 is preferably open in the longitudinal direction L and thus axially in order to insert the magnet 63.

[0138] The two retaining recesses 75, 79 are located at a distance from one another in the longitudinal direction L on opposite sides of the receiving space 35, which serves to accommodate the holding magnet 36. Alternatively, the two retaining recesses 75, 79 could also be configured to accommodate the spring elements 62.

[0139] If the movement of the main magnet 36 in the starting position A0 is limited to the first movement range RI by a stop 61, one of the holding recesses can be omitted and the stop 61 for the main magnet 36 can be arranged there.

[0140] To assemble the shot evaluation device 20, proceed as follows:

[0141] The measuring conductor arrangement 30 and, for example, the coil 32 are arranged on the outside of the attachment part 34. The main magnet 36 is inserted into the axially open side of the attachment part 34, and the attachment part 34 is then connected to the end section 76 of the support device 29.

[0142] The magnets 63 are inserted into the respective first retaining recess 75 or second retaining recess 79 used .

[0143] The at least one circuit board 69 of the evaluation unit 40 is arranged on the circuit board holder 68 of the support device 29. An electrical connection is established between the evaluation unit 40 or the at least one circuit board 69 and the measuring conductor arrangement 30 or coil 32.

[0144] In the exemplary embodiment, the pre-installed assembly is then inserted into the housing body 66, which is then closed by the housing cover 67 of the housing 65 and then preferably cast or glued in place. The housing 65 can then be attached to the movable weapon part 23. Preferably, the housing 65 is inserted into a recess in the movable weapon part and cast, glued in place, or otherwise integrally connected. In particular, the connection between the shot evaluation device 20 and, for example, the housing 65 and the movable weapon part 23 cannot be removed without destruction and is therefore particularly difficult or impossible to manipulate.

[0145] The invention relates to a shot evaluation device 20 for a firearm 21, in particular a handgun, such as a pistol 22. The shot evaluation device 20 is arranged on a weapon part 23, 24, 25, which is subjected to an acceleration effect during a shot and / or a shock acting on the firearm and / or during loading. The shot evaluation device (20) can preferably be permanently attached to a weapon part 23 of the firearm 21 that is movable during the shot or for loading. The shot evaluation device 20 has a carrier device 29, on which a measuring conductor arrangement 30 and a main magnet 36 are arranged so as to be movable relative to one another in a longitudinal direction L. Preferably, the main magnet 36 is movable relative to the carrier device 29, and the measuring conductor arrangement 30 is arranged immovably on the carrier device 29. An evaluation unit 40 is connected to the measuring conductor arrangement 30 for communication purposes, in particular by means of electrical conductors.

[0146] The evaluation unit 40 is preferably battery-free and, in one embodiment, can optionally be designed without a capacitor. The electrical energy for operating the evaluation unit 40 is generated by a relative movement between the measuring conductor arrangement 30 and the main magnet 36, whereby this relative movement also generates the measurement signal M used for the evaluation, in particular an alternating voltage UW.

[0147] The evaluation of the measurement signal M by the evaluation unit 40 serves to detect an event, such as a shot fired from the firearm 21. In particular, fired shots can be differentiated from other events, such as manual loading, impacts, or similar influences. For this purpose, at least part of the generated measurement signal M can be evaluated using predetermined comparison parameters, for example by threshold value comparison. The shot evaluation device 20 is overall a uniformly manageable assembly that can be arranged on a single weapon part 23, 24, 25.
