The present invention relates to a base piece for firearm ammunition, in particular with a caliber of less than 20 mm, comprising a mounting interface for a case jacket for receiving a projectile and a further receptacle for a primer cap for igniting propellant powder of the firearm ammunition, wherein the base piece has a readable code on which ammunition-specific data is stored.

Description

The present invention relates to a base piece for firearm ammunition, in particular with a caliber of less than 20 mm. The present invention further relates to ammunition, in particular with a caliber of less than 20 mm, for a firearm. In addition, the present invention provides a firearm for ammunition, in particular with a caliber of less than 20 mm. The invention also relates to a firearm system comprising ammunition and a firearm. In addition, the present invention relates to a method for calibrating a firearm, in particular its aiming aid, for ammunition, in particular with a caliber of less than 20 mm.

In the field of small caliber ammunition, there are initial attempts to integrate electronics for tracking the position of the projectiles. For example, the German patent application of the applicant DE 102019102722 A1 a projectile with a cavity and a position transmitter arranged in the cavity. The projectile according to DE 102019102722 A1 has basically proven itself and enjoys great popularity.

The DE 102019102722 A1 However, it does not propose any improvement for the necessary zeroing, i.e. the calibration of the weapon system, namely in particular the adjustment between optics, ammunition and weapon, of firearms. Zeroing a firearm, in particular the calibration of its aiming aids such as the open sight, telescopic sight or reflex sight, is sometimes a complex, time-consuming process for the shooter. Furthermore, zeroing generally leads to a high level of noise pollution due to the shots that actually have to be fired. These noises can also give away the shooter's location, which is a disadvantage for hunters and snipers and the like.

DE 4 137 819 A1 , DE 3 830 903 C2 and DE 10 2010 016 963 A1 reveal large-caliber weapon systems with devices arranged on the ammunition for detecting and identifying the ammunition.

DE 2017 004 413 A1 reveals an aiming aid that can be mounted on different weapons.

US 2020/0355450 A1 reveals a reading aid on an ammunition magazine.

US 2012/0126001 A1 , EP 3 367 047 A1 and DE 10 2006 036 257 A1 show different, calibratable aiming aids.

An object of the present invention is to improve disadvantages of the prior art, in particular to accelerate and/or simplify the initial setting of the firearm.

The problem is solved by the features of the independent claims.

According to this, a base piece is provided for firearm ammunition with a caliber of less than 20 mm. Ammunition, also referred to as a cartridge, usually consists of the following components: a cartridge case; a primer cap for igniting the propellant powder; a propellant charge as an energy carrier; and a projectile which is to be fired from a firearm. Multi-part cartridge cases usually comprise at least one base piece facing the primer cap for receiving the primer cap and a case jacket firmly connected to the base piece for receiving the projectile. When the case jacket and base piece are fastened to one another, an outer side of the case jacket can rest against an inner side of the base piece, in other words the base piece can at least partially receive the case jacket. For example, the base piece can have a central recess for receiving the case jacket. The base piece can comprise an annular casing with a central ignition hole and a receptacle for a casing of the multi-part cartridge case that opens into the ignition hole to accommodate a projectile. The receptacle for the casing can open directly into the ignition hole or be separated from the ignition hole by a web. In this case, a through-hole can be provided in the web to fluidly connect the ignition hole to the receptacle. The base piece can be rotationally symmetrical and define a rotation axis that is oriented in the longitudinal direction of the base piece.

According to the first aspect of the invention, the base piece comprises a mounting interface for a case jacket for receiving a projectile and a receptacle for a primer cap for igniting propellant powder of the firearm ammunition. According to the invention, the base piece has a readable code on which ammunition-specific data is stored. The mounting interface for the case jacket can be, for example, a further receptacle, in particular with a round cross-section, in which the case jacket is arranged or fastened in a form-fitting and/or force-fitting manner. The code can be, for example, a bar code or bar code. Optical reading devices, such as a bar code reader, can be used for reading the code. A device, a camera or the like can be used to read the code mechanically and electronically and, if necessary, process it further. The code can also be designed in such a way that it can be read either indirectly or directly. The reading can also be tactile, with contact or contactless. Mechanical, electrical, optical, magnetic, inductive or radio-based technologies can be used in particular for the reading. Ammunition-specific data can be understood to mean, for example, manufacturer-specific, ammunition-specific and/or information that is helpful or necessary for the calibration of the firearm, such as the caliber, which type of cartridge case, which type of ignition, which propellant powder, materials for the projectile and, if necessary, information on any post-treatment steps, weight distributions, such as the center of gravity, or general information on certain internal and/or external ballistics. Because the base of the firearm ammunition contains the ammunition-specific data, a shooter can access the data and calibrate the firearm for each specific ammunition or type of ammunition. From the stored data, the shooter can obtain information relevant to the ballistics of the projectile and calibrate the firearm accordingly, particularly its aiming aid or optics. A major advantage is that the shooter is spared the time-consuming, loud and expensive process of zeroing and adjusting the firearm. Furthermore, the firearm can be adjusted much more precisely and in an optimized manner, since settings for the firearm based on experience or calculation values can be used depending on the stored data.

The code, the information, can be applied to the base piece using various techniques. The code, if it is a 1-D (“bar”) or 2-D (“QR”) code, can be applied e.g. by printing (e.g. pad printing) physicochemically or by etching chemically or physically, e.g. by a laser. However, the code could also be digitally located on an RFID chip (RFID for “radio-frequency identification”). According to a development of the present invention, telemetry transmitters can be used. Telemetry or remote measurement can generally be the transmission of signals from a signal transmitter located at any location to a spatially separate location, in particular where the transmitted signals can be collected, recorded and/or evaluated. For example, the transmitter can be an RFID transponder. RFID transponders differ, for example, according to the transmission frequency, although according to the present invention there are no restrictions in this regard. The structure of an RFID transponder can be constructed, for example, as follows: an antenna, at least one circuit for receiving and transmitting (transceiver), such as a microcontroller, and a memory that contains the preferably unchangeable identity of the projectile. It is clear that any other type of transmitter that is suitable for the purpose of the invention is included in the disclosure content of the present application, in particular the requirements for transmission power in the narrow, metallic environment in the firearm, dimensioning and transmission strength in order to be accommodated in it and to enable data reading.

In an exemplary embodiment of the base piece according to the invention, the code is arranged on a front surface on the primer cap holder side, facing away from the case jacket mounting interface. The front surface is oriented essentially perpendicular to the longitudinal axis of the base piece and/or opposite to the firing direction of the firearm. This position has proven to be advantageous for the code in terms of easy accessibility for reading the code. The front surface is generally ring-shaped and has the holder for the primer cap in its center.

According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, ammunition is provided for a firearm, in particular with a caliber of less than 20 mm.

Ammunition, also referred to as a cartridge, usually consists of the following components: a cartridge case; a primer cap for igniting the propellant powder; a propellant charge as an energy carrier; and a projectile which is to be fired from a firearm. Multi-part cartridge cases usually comprise at least one base piece facing the primer cap for receiving the primer cap and a case jacket firmly connected to the base piece for receiving the projectile. When the case jacket and base piece are fastened together, an outer side of the case jacket can rest against an inner side of the base piece, in other words, the base piece can at least partially receive the case jacket. For example, the base piece can have a central recess for receiving the case jacket. The base piece can have an annular jacket with a central ignition hole and a receptacle for a case jacket of the multi-part cartridge case which opens into the ignition hole. for receiving a projectile. The receptacle for the casing can open directly into the ignition hole or be separated from the ignition hole by a web. In this case, a through hole can be provided in the web to fluidly connect the ignition hole to the receptacle. The base piece can be rotationally symmetrical and define an axis of rotation that is oriented in the longitudinal direction of the base piece.

The ammunition according to the invention comprises a case jacket for receiving a projectile and a base piece, designed in particular according to one of the previously described aspects or exemplary embodiments, for receiving a primer cap for connection to the case jacket.

The ammunition according to the invention has a readable code arranged on a front surface of the base piece on the primer cap receiving side, facing away from the case jacket receiving side, and/or on an outer circumference of the case jacket, on which ammunition-specific data is stored. The code can be a bar code or barcode, for example. Optical reading devices such as a bar code reader, a camera or the like can be used for reading the code, for example, in order to read the code mechanically and electronically and, if necessary, to process it further. The code can also be designed in such a way that it can be read either indirectly or directly. The reading can also be done tactilely, with contact or contactless. Mechanical, electrical, optical, magnetic, inductive or radio-based technologies can be used for reading. Ammunition-specific data can be understood as information that is manufacturer-specific, specific to the ammunition and/or useful or necessary for calibrating the firearm, such as the caliber, the type of cartridge case, the type of ignition, the propellant powder, the materials used for the projectile and, if applicable, information on any post-processing steps, weight distributions such as the center of gravity, or general information on certain internal and/or external ballistics. Because the base of the firearm ammunition contains the ammunition-specific data, a shooter can access the data and calibrate the firearm in a way that is specific to the ammunition or type of ammunition. The shooter can use the stored data to obtain information relevant to the ballistics of the projectile and calibrate the firearm accordingly, particularly its aiming aid or optics. A key advantage is that the shooter is spared the time-consuming, loud and expensive process of zeroing and adjusting the firearm. Furthermore, the firearm can be adjusted much more precisely and optimally, since, depending on the stored data, settings for the firearm can be used that are based on experience or calculated values.

According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a firearm is provided for an ammunition designed in particular according to one of the previously described aspects or exemplary embodiments, in particular with a caliber of less than 20 mm.

Ammunition, also referred to as a cartridge, usually consists of the following components: a cartridge case; a primer cap for igniting the propellant powder; a propellant charge as an energy carrier; and a projectile that is to be fired from a firearm. Multi-part cartridge cases usually comprise at least one base piece facing the primer cap for receiving the primer cap and a case jacket that is firmly connected to the base piece for receiving the projectile. When the case jacket and base piece are fastened to one another, an outer side of the case jacket can rest against an inner side of the base piece, in other words, the base piece can at least partially receive the case jacket. For example, the base piece can have a central recess for receiving the case jacket. The base piece can comprise an annular jacket with a central ignition hole and a receptacle that opens into the ignition hole for a case jacket of the multi-part cartridge case for receiving a projectile. The receptacle for the case jacket can open directly into the ignition hole or be separated from the ignition hole by a web. In this case, a through hole can be provided in the web to fluidly connect the ignition hole to the receptacle. The base piece can be rotationally symmetrical and define an axis of rotation that is oriented in the longitudinal direction of the base piece.

The firearm according to the invention comprises a barrel with a cartridge chamber and an ammunition shaft for receiving an ammunition magazine with the ammunition or ammunition. The cartridge chamber is located, for example, in a rearmost section of the barrel bore of the firearm in relation to the firing direction. Towards the rear of the firearm, the cartridge chamber is closed by a closure which prevents the escape of propellant gases after the projectile has been fired.

According to the further aspect of the invention, the firearm is characterized by a reading device arranged in the area of the cartridge chamber and/or the ammunition shaft for reading an ammunition-side code on which ammunition-specific data is stored.

The code can be a barcode or a bar code, for example. Optical reading devices such as a barcode reader, a camera or the like can be used for reading the code, for example, to read it mechanically and electronically and, if necessary, to process it further. The code can also be designed in such a way that it can be read either indirectly or directly. Reading can also be done tactilely, with contact or contactless. Mechanical, electrical, optical, magnetic, inductive or radio-based technologies can be used for reading. Ammunition-specific data can be understood to mean, for example, manufacturer-specific, ammunition-specific and/or information that is helpful or necessary for calibrating the firearm, such as the caliber, which type of cartridge case, which type of ignition, which propellant powder, materials for the projectile and, if necessary, information on any post-processing steps, weight distributions such as the center of gravity, or general information on certain internal and/or external ballistics. Because the base of the firearm ammunition contains the ammunition-specific data, a shooter can access the data and calibrate the firearm for each specific ammunition or type of ammunition. From the stored data, the shooter can obtain information relevant to the ballistics of the projectile and calibrate the firearm accordingly, particularly its aiming aid or optics. A major advantage is that the shooter is spared the time-consuming, loud and expensive process of zeroing and adjusting the firearm. Furthermore, the firearm can be adjusted much more precisely and in an optimized manner, since settings for the firearm based on experience or calculation values can be used depending on the stored data.

According to an exemplary embodiment of the firearm according to the invention, the reading device is arranged and/or set up to read the code regardless of the orientation of the ammunition in the firearm or only when the ammunition in the firearm is in a predetermined orientation. According to an exemplary development, the firearm further comprises a device for rotating the ammunition, in particular in the firearm barrel. For example, the reading device is arranged in a fixed position on the firearm and/or has a predetermined reading or scanning area in which the ammunition-side code is to be arranged so that the reading device can read it. According to this embodiment, the rotation device can be used for the ammunition, with which the ammunition can be rotated, in particular can be rotated in such a way that the reading device can read the code. In an alternative embodiment, the reading device is either movably arranged on the firearm and/or has an enlarged reading or scanning area, so that the ammunition-side code can be read by the reading device, regardless of how the ammunition is arranged or oriented in the firearm barrel, in particular the cartridge chamber and/or the ammunition shaft.

This ensures that each piece of ammunition is read out by the firearm before it is fired in order to retrieve the data stored on the code. This ensures that the ammunition-specific data can be read out for each piece of ammunition used before firing in order to calibrate the firearm, in particular its aiming aid, based on the data read out.

In an exemplary embodiment of the firearm according to the invention, the firearm further comprises an aiming aid which is connected to the reading device in a signal-transmitting manner. According to an exemplary development, the aiming aid is connected to the reading device in a signal-transmitting manner in such a way that the aiming aid can be calibrated depending on the data read out. The aiming aid can be calibrated, for example, automatically in response to the reading out and depending on the data read out. Because the ammunition-specific data can include data and information relevant to the ballistics of the ammunition, the signal transmission between the reading device and the aiming aid enables the aiming aid to be adjusted to achieve optimal ballistics without the need for complex zeroing or manual adjustment by the shooter.

In a further exemplary embodiment of the firearm according to the invention, the firearm further comprises a control unit connected to the aiming aid in a signal-transmitting manner and a motor for adjusting the aiming aid. The control unit can either be part of the reading device or represent a separate component. According to an exemplary development, the control unit is designed to adjust the aiming aid depending on the data read out by the reading device. calibrate. The control can be set up to operate the motor that controls or activates the aiming aid in order to implement the information obtained from the read data, which in particular involves calibrating the firearm, in particular its aiming aid.

According to a further exemplary embodiment of the firearm according to the invention, the firearm further comprises a memory on which firearm-specific, in particular aiming aid-specific, data corresponding to the ammunition-specific data is stored, or a communication interface for retrieving firearm-specific, in particular aiming aid-specific, data corresponding to the ammunition-specific data from an external data storage device, such as a cloud. It is thus possible, among other things, for the calibration of the firearm, in particular the aiming aid, to take place automatically, in particular without user intervention. The firearm-specific data corresponding to the ammunition-specific data, which can contain, for example, various setting parameters relating to the aiming aid, the trigger, possible weight adjustments or instructions to the shooter, also ensure optimal calibration of the firearm. The data-supported calibration avoids errors by the shooter when setting up or calibrating the firearm. Furthermore, the firearm can be deployed much faster and the shooter can concentrate exclusively on firing the projectile without having to worry about calibrating the firearm.

The memory can contain a database with a wide variety of ammunition types, in which firearm-specific data, such as setting parameters, are stored for each typical ammunition type. When the ammunition is inserted and the code is identified using the reading device, the database is queried to search for the specific ammunition and, if there is an entry in the database for the specific ammunition type, the firearm-specific data is read out and applied to the firearm. This means that the firearm is automatically set or calibrated based on the ammunition-specific data.

According to an exemplary development of the firearm according to the invention, the control is set up to calibrate the aiming aid depending on the data read out by the reading device and taking into account the firearm-specific data, in particular the aiming aid-specific data. Because the firearm according to the invention contains both the information or data on the ammunition used and reads out the firearm-specific data associated with the specific ammunition, the control can react quickly and calibrate the aiming aid individually for each ammunition and/or firearm.

In a further exemplary embodiment of the present invention, the reading device or a further reading device is arranged at a barrel end in the firing direction or on an ammunition ejector of the firearm. As a result, after the ammunition has been fired and the projectile contained in the ammunition has been fired, the firearm is able to read the ammunition after firing. Information can thus be subsequently obtained from the firing, which can then be used to subsequently adjust the firearm component. For example, this design of the firearm can be used to generate the information necessary for fine-tuning the firearm by means of a calibration shot, which is fired initially, so that the firearm adjusts itself or can be adjusted automatically, in particular, before the first relevant shot.

In a further exemplary embodiment of the firearm according to the invention, the firearm further comprises a protective device associated with the reading device, which is designed and/or can be arranged in such a way as to protect the reading device from the byproducts that occur when the ammunition is fired, such as high temperatures, combustion gases, etc. It has been found that it may be necessary to at least partially protect or shield the sensitive reading device in order to increase its service life and/or to prevent impairment of the reading capability of the reading device.

In an exemplary further development, the protective device can assume an active state in which it protects the reading device, in particular shielding it from the ammunition, and a passive state in which it releases the reading device. This allows the optimal configuration to be set depending on the situation. Alternatively or additionally, the protective device can be mounted so that it can move relative to the reading device, for example it can be extended and retracted in relation to the gun barrel, or it can be pivoted in and out.

According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a firearm system comprising an ammunition according to the invention and an inventive A firearm according to the invention is provided. The ammunition or the firearm can be designed according to one of the aspects or exemplary embodiments described above.

In an exemplary embodiment of the firearm system according to the invention, the firearm further comprises a marker, depending on which the ammunition can be aligned when loading the firearm in order to set a predefined orientation of the ammunition. In particular, in the event that the reading device comprises a predetermined trigger or scan area or is dependent on the ammunition being in a certain orientation in the cartridge chamber and/or ammunition shaft, the marker can provide the shooter with an optical, haptic and/or acoustic signal so that he or she inserts the ammunition in the correct orientation. Subsequent adjustment of the ammunition within the firearm can thus be avoided.

According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a method for adjusting or calibrating a firearm for ammunition, in particular with a caliber of less than 20 mm, is provided.

According to the method according to the invention, a firearm, in particular designed according to the invention, with a reading device for reading a code on the ammunition side is loaded with ammunition, in particular designed according to the invention, with a readable code on which ammunition-specific data is stored.

Furthermore, when loading the ammunition, the ammunition-side code is read by the firearm's reading device.

Furthermore, a firearm component, such as an aiming aid, is adjusted, in particular calibrated, based on the ammunition-specific data on the code.

According to a further aspect of the present invention, which can be combined with the preceding aspects and exemplary embodiments, a method for operating a firearm and/or a firearm system is provided. The firearm and/or the firearm system can be designed according to some of the aspects or exemplary embodiments described above.

In the following description of exemplary embodiments of the present invention, a base piece according to the invention is generally provided with the reference number 1, an ammunition according to the invention with the reference number 10 and a firearm according to the invention with the reference number 20.

1 shows a schematic exemplary schematic diagram of a firearm 20 according to the invention, which has a firearm barrel 23 with a cartridge chamber 25 in which an ammunition 10 according to the invention is arranged. The firearm 20 also comprises an aiming aid 27, here an optical aiming aid, namely a telescopic sight.

In 1 An essential aspect of the present invention is schematically indicated. The ammunition 10 arranged in the cartridge chamber 25 has a readable code 3 (for example 2 ) on which ammunition-specific data is stored. This data can be read by a firearm-side reading device 30 (for example 6 ) and further processed, for example to adjust or calibrate the firearm, in particular the aiming aid 27. This process is indicated schematically by the arrows with the reference numerals 29 and 31, which on the one hand indicate communication and on the other hand a control for setting or calibrating the aiming aid 27. According to one aspect of the present invention, the aiming aid 27 can be calibrated depending on the ammunition-specific data, so that a complex, loud and time-consuming zeroing of the firearm can be dispensed with.

The firearm 20 can have a control unit connected to the aiming aid 27 in a signal-transmitting manner and a motor for adjusting the aiming aid 27. The control unit can be set up to calibrate the aiming aid 27 depending on the data read out by the reading device 30. The firearm can also comprise a memory on which firearm-specific, in particular aiming aid-specific, data corresponding to the ammunition-specific data can be stored or a communication interface for retrieving firearm-specific, in particular aiming aid-specific, data corresponding to the ammunition-specific data from an external data storage unit, such as a cloud. The control unit can be set up to calibrate the aiming aid 27 depending on the data read out by the reading device 30 and taking into account the firearm-specific, in particular aiming aid-specific, data.

The exemplary embodiment of an inventive ammunition 10 according to 2 shows a further aspect of the present invention. The ammunition 10 basically comprises the following main components: a base piece 1 facing the direction of fire, which serves to receive a primer cap 5 and to connect it to a case jacket 7; a case jacket 7 which is connected to the base piece 1 and is designed to receive a projectile 9; and a projectile 9 oriented in the direction of fire. The readable code 3 is arranged on a front surface 11 of the base piece 1 facing the direction of fire, which contains the specific or individual data for the specific ammunition 10, which can be read by a reading device 30, in particular on the firearm, so that the firearm, in particular the aiming aid 27, can be adjusted, in particular calibrated. The arrangement of the code 3 on the front surface 11 facing the direction of fire ensures its accessibility for the reading device 30.
