Description

FIELD OF THE INVENTION

The invention relates to a system comprising a striking device for a firearm, the striking device having a firing pin and a triggering unit in operative connection with the firing pin, the triggering unit being designed to trigger or effect a triggering movement of the firing pin from a rest position to a firing position .

STATE OF THE ART

In the field of firearms technology, manifold variations of the structure of firearms are known. As a rule, the firearms comprise at least one barrel, an ammunition chamber in which the cartridge intended for the shot can be stored, a grip element, an operating unit designed as a trigger and a striking device with a firing pin and a trigger unit. The trigger unit of the striking device is usually designed mechanically and connected to a trigger of the firearm so that when the trigger is operated, the firing pin is moved by means of the trigger unit in the direction of the ammunition chamber in order to ignite the ignition charge of a cartridge located in the ammunition chamber. The firing pin in the firing device is moved from a rest position by means of the trigger unit, in which there is generally no contact with a cartridge located between the firing pin and the ammunition chamber and the firearm is thus in a safe state in which no shot is released, accelerated and moved into a firing position in which the firing pin usually protrudes in sections into the ammunition chamber, so that the firing pin strikes the cartridge located in the ammunition chamber, igniting the detonating charge and thus triggering a shot. This movement of the firing pin from the rest position or safety position into the firing position is referred to below as the triggering movement.

In conventional firearms with a mechanical trigger unit and a manually operated trigger that is permanently installed with the firearm, the actuation of the trigger in connection with the mechanism of the trigger unit acts on the firearm, which must be compensated for by appropriate body movements in order to be able to rest from the targeted point to prevent. If this compensation does not take place, the shooting results are much worse, which is a problem especially for inexperienced shooters.

GB 224319 A discloses a firearm with a firing pin which can be actuated via an electromagnetic trigger device. An electro-magnetically actuated safety mechanism is provided as a safety device, by means of which a locking arrangement can be moved from a secured to an unlocked position or vice versa. It can be triggered by an ignition switch or a contact at a remote location.

US 2009/158922 A1 describes an actuation unit that can be triggered by radio via a transmission device, the actuation unit being attached to the trigger of a conventional firearm. If the corresponding button on the transmitter is actuated, the transmitter wirelessly sends an actuation signal to the actuation unit, which then triggers the trigger by activating a motor.

OBJECT OF THE INVENTION

It is therefore an object of the invention to overcome the disadvantages of the prior art and to provide a system comprising a striking device for a firearm and an operating unit for actuating the striking device, by means of which the influence of the actuation of the striking device and the manual actuation of the operating unit to the target accuracy is minimized.

DISCLOSURE OF THE INVENTION

This object is achieved in a system according to the invention according to claim 1.

The system preferably consists of an impact device and an operating unit.

The solution according to the invention thus comprises two synergistically interacting partial aspects: On the one hand, the trigger unit is not designed purely mechanically, that is, as a lever or hammer mechanism, but rather as an electromagnetic trigger unit. Tilting moments due to the actuation of the triggering unit can thus be avoided, since only an electromagnetic force is responsible for the effect or triggering of the generally linear triggering movement of the firing pin. Both active electromagnetic release units are provided here, which cause the firing pin to move directly by exerting an electromagnetic force, and passive release units are provided which, for example, block the release movement by exerting the electromagnetic force, so that by changing the electromagnetic force Force the triggering movement can be triggered by a pretensioning force acting on the firing pin. Thus, the generation of any tilting or torque caused by a mechanism can be effectively prevented.

The second partial aspect relates to the actuation of the firearm itself. Conventional firearms according to the prior art have an operating unit designed as a trigger, the trigger being mechanically coupled to the trigger unit and integrated into the firearm. Thus, in order to operate the firearm, the hand on the firearm must inevitably execute a movement, so that an additional turning or tilting moment acts on the firearm through the trigger movement. According to the second partial aspect of the invention, the actuation signal is transmitted wirelessly between the operating unit and impact device, that is to say for example by radio signal, WLAN, Bluetooth or infrared signal. This means that no structural and / or mechanical connection between the operating unit and the firearm or striking device is necessary in order to trigger or effect the triggering movement of the firing pin. For example, the control unit can be held in one hand while the other hand holds the firearm with the striking device and fixes the target. It is also conceivable that the first hand with the operating unit is placed on the barrel of the firearm. Since the shooter's physical interaction is limited to operating the control unit, neither a tilt nor a torque act on the firearm itself.

If in the following, for the sake of simplicity, the triggering or firing of a shot is mentioned, it goes without saying that this is to be understood as triggering or effecting the triggering movement with regard to the striking device and the reference to the shot of a firearm is merely the better Understanding serves.

It can advantageously be provided that the range of the transmitting or receiving device is in a short or medium range. It can be provided that the range is between 5 cm and 250 cm, in particular between 10 cm and 200 cm, preferably between 15 cm and 150 cm, preferably between 20 cm and 100 cm. Thus, the radius of influence for interference signals can be reduced and it must be ensured that the triggering of the striking device occurs only in the immediate vicinity of the striking device, in order to achieve greater safety during use.

In order to increase the shooting accuracy of a firearm, in that the shot does not have to be triggered by the same hand that holds the firearm, but by simple electronic means that can be held in the other hand, a system is thus proposed, the system comprising a striking device for a firearm, the striking device having a firing pin and an electromagnetic trigger unit, the electromagnetic trigger unit being designed to trigger or cause a triggering movement of the firing pin; and an actuatable operating unit, wherein the actuation of the operating unit triggers or effects the triggering movement of the firing pin, the operating unit comprising a transmitting device for sending an actuating signal via a wireless connection and the striking device comprising a receiving device for receiving the actuating signal, the actuating signal by means of the transmitting device on the receiving device can be sent and the triggering movement of the firing pin is triggered or effected when the actuating signal is received.

The advantages of the invention with regard to the increased shooting accuracy can also be achieved when a conventional firearm can be equipped or retrofitted with the system according to the invention. A conventional firearm is characterized in that the striking device has a mechanical release unit that can be connected to a trigger of the firearm. It is therefore provided in the system according to the invention that the striking device has a mechanical release unit that can be connected to a trigger of the firearm.

Correspondingly, by combining the electromagnetic release unit with a mechanical release unit, a The system achieves that it has two different firing modes: on the one hand, remote actuation by means of the operating unit via the electromagnetic trigger unit with improved accuracy and on the other hand direct actuation via the mechanical trigger unit, which can be actuated directly via the trigger of the firearm. It is thus possible for the user to switch between the two shooting modes, for example to use remote triggering on the shooting range and direct triggering in the event of a rapid reaction to a dangerous situation. It is also possible in the event of a malfunction - for example if one of the energy supply units is not charged or the trigger has a malfunction - to be able to fire a shot using the other firing mode. The different interactions between the mechanical trigger unit and the electromagnetic trigger unit described below, in particular whether a firing pin is actuated by both trigger units or whether a firing pin is provided for each trigger unit, comes about when the mechanical and electromagnetic trigger unit are basically combined in one Impact device does not work.

According to the invention it is provided that the striking device comprises a mechanical triggering unit that can be connected to a trigger of the firearm, the mechanical triggering unit cooperating with the firing pin in order to trigger the triggering movement of the firing pin when the trigger is actuated. In addition to the aforementioned positive effects of the two possible firing modes, the design with a single firing pin, which interacts with both trigger units, leads to a solution that achieves an optimal position of the firing pin and reduces the number of moving parts. It can additionally be provided, for example, that a manually operable selection switch is provided, by means of which the shooter selects which of the two shooting modes is to be active before operating the trigger or the operating unit. The selection switch can be designed so that it connects to the other components of the impact device cooperates to either activate the mechanical trip unit and deactivate the electromagnetic trip unit or vice versa.

Alternatively, the invention provides that the striking device comprises a mechanical trigger unit that can be connected to a trigger of the firearm and a further firing pin, the mechanical triggering unit cooperating with the further firing pin in order to trigger a triggering movement of the further firing pin when the trigger is actuated. In addition to the previously mentioned positive effects of the two possible shooting modes, the design with two separate firing pins, each cooperating with one of the triggering units, means that both triggering units are in a ready-to-trigger state without prior selection. Even if one of the two firing pins should be immovable due to a malfunction, a shot can be triggered by means of the other firing pin.

Due to the wireless transmission of the actuation signal between the operating unit and the striking device, it is advantageous if the operating unit and the striking device are designed as separate components. The operating unit can thus be moved and handled freely in relation to the striking device. One embodiment variant of the invention therefore provides that the operating unit and the striking device are designed as separate components.

In one embodiment variant of the invention it is provided that the striking device comprises a first energy supply unit and / or that the Control unit comprises a second power supply unit. The electrical energy required for operation is provided by the energy supply units. The energy supply units can be, for example, energy stores, such as batteries or accumulators, which enable mobile operation. However, it is also conceivable that the energy supply units, in particular for stationary use, for example in shooting ranges, are fed via the electrical network.

In order to increase operational safety and to prevent unintentional triggering of the striking device by an unauthorized person (i.e. not the shooter himself), a further variant embodiment provides that the transmission device of the operating unit is designed to transmit the actuation signal with an identification code that can be clearly assigned to the operating unit to be provided, and that the receiving device of the striking device is designed to check whether an identification code of the received actuation signal matches the identification code of the operating unit assigned to the striking device, and to trigger or effect the triggering movement of the firing pin only when the actuation signal from the the control unit assigned to the impact device originates. In order to effect the assignment of transmitting device and receiving device, it can be provided that the control unit and impact device have to be paired with one another at predetermined time intervals, for example by exchanging a randomly generated code so that only one control unit is assigned to each impact device or only one impact device is assigned to each operating unit. By comparing the identification code, it can thus be ensured that the actuation signal has been sent by the correct operating unit and that the command for triggering or effecting the triggering movement is actually to be carried out by the striking device. For example, the transmitting device can have means for generating the identification code and / or the receiving device can have means for comparing the Have identification code with a stored identification code of the assigned operating unit. The corresponding means can be designed as microprocessors or microchips, for example.

To increase the security during the transmission of the actuation signal between the transmitting device and the receiving device and to reduce the risk that an unauthorized person can read out and copy or manipulate the transmitted actuating signal, a further variant of the system according to the invention provides that the transmitting device of Operating unit is designed to encrypt the actuation signal and that the receiving device of the striking device is designed to decrypt the received actuation signal. For example, the transmitting device can have means for encrypting the actuation signal and / or the receiving device can have means for decrypting the actuation signal. The corresponding means can be designed as microprocessors or microchips, for example. It is also conceivable that the means for encryption also generate the identification code and / or that the means for decryption also carry out the comparison of the identification code.

In order to be able to make the striking device as space-saving as possible on the one hand and to achieve the best possible positioning of the two firing pins in relation to the cartridge to be fired on the other hand, when the striking device is installed in a firearm in the operating state, a further variant of the system according to the invention provides that the The firing pin and the further firing pin are arranged to run parallel to one another or that the firing pin and the further firing pin are arranged at least in sections to run coaxially to one another. If the two firing pins are coaxial in sections, it is preferred if one of the The firing pin has a cavity along its longitudinal axis and the other firing pin is arranged at least in sections within the cavity.

Another embodiment of the invention provides that the striking device comprises a mechanical trigger unit that can be connected to a trigger of the firearm and a further firing pin, the mechanical triggering unit cooperating with the further firing pin in order to trigger a triggering movement of the further firing pin when the trigger is actuated. In addition to the previously mentioned positive effects of the two possible shooting modes, the design with two separate firing pins, each cooperating with one of the triggering units, means that both triggering units are in a ready-to-trigger state without prior selection. Even if one of the two firing pins should be immovable due to a malfunction, a shot can be triggered by means of the other firing pin.
In order to be able to make the striking device as space-saving as possible on the one hand and to achieve the best possible positioning of the two firing pins in relation to the cartridge to be fired on the other hand, when the striking device is installed in a firearm in the operating state, a further variant of the system according to the invention provides that the The firing pin and the further firing pin are arranged to run parallel to one another or that the firing pin and the further firing pin are arranged at least in sections to run coaxially to one another. If the two firing pins run coaxially in sections, it is preferred if one of the firing pins has a cavity along its longitudinal axis and the other firing pin is arranged at least in sections within the cavity.

According to a preferred embodiment of the invention, it is provided that the electromagnetic release unit comprises an electromagnet, wherein the firing pin can either be held in the rest position by means of the electromagnet against a biasing force acting on the firing pin, or the firing pin can be brought into the firing position by means of the electromagnet . The use of an electromagnet enables the electromagnetic release unit to be constructed in a particularly simple manner.

On the one hand, the electromagnet can be designed in such a way that the triggering movement is actively brought about by an exerted electromagnetic force. For example, the electromagnet can therefore be designed as a lifting magnet so that the firing pin having an armature can be moved at least from the rest position into the firing position by the energization of the electromagnet, preferably also vice versa.

On the other hand, the electromagnet can also be designed in such a way that the exerted electromagnetic force holds the firing pin in the rest position against a pretensioning force, the electromagnet being designed as a holding magnet, for example. The firing pin can be preloaded, for example, by means of a spring, so that the firing pin is preloaded in the direction of the firing position by the spring force. When current flows through the electromagnet, the electromagnetic force acts as a holding force on an armature of the firing pin. When the electromagnet is de-energized or the voltage is reduced, the pre-tensioning force is greater than the holding force, so that the triggering movement of the firing pin is triggered.

In order to avoid unintentional triggering of the striking device and thus to increase operational safety, a further embodiment of the invention provides that the striking device comprises a safety device designed to block the triggering movement of the firing pin, preferably the firing pin and the further firing pin. The Safety device can for example be designed as a mechanical safety device so that the impact device can be brought from a secured position in which the release movement is blocked to an unlocked position in which the release movement is free by actuating the safety mechanism. Electro-magnetic safety devices that work according to the same principle are also conceivable. As a rule, the safety device can be actuated manually, whereby it is also conceivable that the actuation takes place via a safety mechanism provided in the firearm and cooperating with the striking device. If there are several trigger units or firing pins, it is advantageous if the triggering movement of all firing pins can be blocked equally by means of the safety device.

In a further embodiment it is provided that the electromagnetic release unit comprises a safety switch, the receiving device being able to be switched from a ready-to-receive state to a non-ready-to-receive state and vice versa by actuating the safety switch. By simply activating or deactivating the receiving device, unintentional firing of a shot can be prevented in a simple manner by accidentally actuating the control unit, since the receiving device is activated or deactivated before and after firing a shot or a series of shots by actuating the safety switch can. It can also be provided that the safety switch has a time recording unit in order to automatically deactivate the receiving device after an adjustable time after activation.

In order to improve the handling of the control unit, in particular if the control unit and the striking device represent separate components that are not structurally connected to one another, a further embodiment of the invention provides that the control unit is arranged in a housing, the Housing has at least one actuating element by means of which the actuating signal can be triggered. The housing can be made of plastic or metal, for example. Because all electronic components of the operating unit are preferably arranged within the housing, the electronics can be protected from external, environmental influences. The actuating element can be, for example, a push button, a switch or some other element that can be brought into at least two positions, with a fingerprint sensor or some other electronic device also being conceivable, for example. The actuation element can be connected to an electronic component or switch which is arranged in the interior of the housing and which activates or responds to the transmission device in order to send the actuation signal.

Another possibility of improving the operating safety is achieved in a further embodiment of the invention in that the housing has an unlocking element, the operating unit being designed in such a way that the actuating element can only be actuated and / or the transmission device is only activated if the unlocking element is previously in an unlocked position has been brought. It can advantageously be provided that both the unlocking element and the actuating element have to be actuated simultaneously in order to trigger a shot or to generate the actuating signal. The unlocking element can for example mechanically block the movement of the actuating element so that the actuating signal cannot be generated by means of the actuating element without first unlocking the unlocking element. It is also conceivable that the transmission device is in the standard setting in a state that is not ready for transmission and can only be switched to a state that is ready for transmission by actuation of the unlocking element. This can also prevent the actuation signal from being generated without the unlocking element having been actuated. Is particularly advantageous it when the actuating element and the unlocking element are arranged on the housing in such a way that two components of one hand of the shooter - for example the thumb and one of the other fingers of the same hand or the palm and thumb - have to be moved independently of one another in order to be able to actuate both the unlocking element and the actuating element.

The object mentioned at the beginning is also achieved according to the invention by a firearm with a system according to the invention, the striking device being built into the firearm and the operating unit being arranged in a housing separate from the firearm. By integrating the striking device into a firearm, the operating unit can actually trigger a shot if a cartridge is in the ammunition chamber of the firearm and the firearm is unlocked, for example by actuating the safety device and / or by actuating the safety switch. Because the control unit or at least the transmitter and other electronic components of the control unit are arranged in the housing and the housing is not structurally connected to the firearm or the striking device, the firearm can be held in one hand and the control unit in the other. As mentioned above, the housing can have an actuating element and / or an unlocking element. The improvement in the shooting accuracy of the firearm described at the beginning can thus be achieved by triggering a shot by means of the operating unit.

The system according to the invention is particularly suitable for use in handguns, such as pistols, or in handguns, such as rifles, shotguns, rifles, sniper rifles or assault rifles, the length of the barrel of the firearm having no significant influence on the functioning of the invention. Therefore, according to one embodiment of the invention, it is provided that the firearm is a handgun or a handgun.

BRIEF DESCRIPTION OF THE FIGURES

The invention will now be explained in more detail using an exemplary embodiment. The drawings are exemplary and are intended to explain the idea of the invention, but in no way restrict it or reproduce it conclusively.

WAYS OF CARRYING OUT THE INVENTION

Fig. 1 shows a schematic representation of a variant embodiment of the system according to the invention, the system comprising, on the one hand, an impact device 1 and, on the other hand, an actuatable operating unit 2. In order to be able to better represent the individual components of the control unit, the illustrations are not to scale or the size relationships do not correspond to reality. In the present exemplary embodiment, the system consists of a striking device and an operating unit.

In the operating state (see Fig. 3 ) the striking device 1 is usually integrated into a firearm 20 and is used to deliver a shot by igniting the ignition charge of a cartridge 21 located in an ammunition chamber of the firearm 20, which for better understanding is also in the Figures 1 and 2 is shown, but does not belong to the system. For this purpose, the striking device 1 has at least one striking pin 3, 12, which can be brought from a rest position to a firing position via a triggering unit 4, 10. As a result of the triggering movement which the at least one firing pin 3.12 passes through between the rest position and the firing position, the firing pin 3.12 strikes a bottom of the cartridge 21 in the firing position and ignites the firing charge of the cartridge 21 through the impact energy, which subsequently causes it a propellant charge of the cartridge 21 is ignited, so that propellant gases are released. These propellant gases ultimately accelerate a projectile from the cartridge 21 in a barrel of the firearm 20 and thus fire a shot.

In the present exemplary embodiment, the striking device 1 comprises both an electromagnetic trigger unit 4, which cooperates with the firing pin 3 and interacts with the operating unit 2, and a mechanical trigger unit 10 which cooperates with a further firing pin 12 and is actuated by a trigger 11 of the firearm 20 is, the trigger 11 for better understanding also in the Figures 1 and 2 is shown. It is thus a striking device 1 by means of which two shot modes are enabled, on the one hand via the conventional actuation of the trigger 11 and on the other hand via the triggering of a shot via the control unit 2, described in detail below. It goes without saying that for the function Due to the interaction of electromagnetic release unit 4 and operating unit 2 described below, the additional mechanical release unit 10 does not necessarily have to be present, although synergistic or additional positive effects result from the combination of the two release units 4, 10 in one impact device.

In the present exemplary embodiment, the electromagnetic trigger unit 4 is designed in such a way that it moves the triggering movement of the firing pin 3 from the rest position to causes the fire position. In order to bring about the triggering movement, the electromagnetic triggering unit 4 can be used to generate an electromagnetic force which moves the firing pin 3 from the rest position to the firing position.

In the illustrated embodiment, the electromagnetic release unit 4 comprises an electromagnet 13 which is connected to a first energy supply unit 8 and a receiving device 6 in a receiver circuit. The receiving device 6 is designed on the one hand to wirelessly receive an actuation signal 7 and on the other hand is designed such that the triggering movement of the firing pin 13 is effected when the actuating signal 7 is received and the receiving device 6 is in a ready-to-receive state.

In the present exemplary embodiment, the triggering movement of the firing pin 3 is effected in such a way that the electromagnet 13, which is designed as a lifting magnet, is energized, preferably for a predefined period of time, and through the electromagnetic force exerted, the firing pin 3 is moved into the firing position by an armature 14 attached to the firing pin 3 is moved.

A partial aspect of the invention can therefore be seen in the fact that only electrical circuits are activated for the triggering movement of the firing pin 3 upon receipt of the actuation signal 7, which causes a linear movement of the firing pin 3 due to the electromagnet 13, so that nothing is caused by the electromagnetic triggering unit 4 Conditional torque and / or tilting moment acts on the striking device 1 and, in the application, on the firearm 20 or the shooter's hand. This increases the shooting accuracy or target accuracy, since no compensatory movements of the shooter are necessary in order to compensate for the turning and / or tilting moment.

In order to address the electromagnetic release unit 4 and to effect the release movement, an actuatable control unit 2 is provided. According to the invention, the operating unit 2 comprises a transmitting device 5, by means of which the actuating signal 7 can be generated and transmitted wirelessly to the receiving device 6 of the electromagnetic release unit 4. If the operating unit 2 is now actuated, in the present exemplary embodiment the actuating element 18 is provided for this purpose, the transmitting device 5 sends the actuating signal 7 to the receiving device 6, with the triggering movement of the firing pin upon receipt of the actuating signal 7 by the receiving device 6 - as described above 3 is effected in the striking device 1 in order to fire a shot by means of the firearm 20 when used.

Another aspect of the invention is that the wireless transmission of the actuation signal 7 between operating unit 2 and striking device 1 means that there is no physical or structural connection between operating unit 2 and striking device 1 or between operating unit 2 and firearm 20 through which a cable or the like is performed. It is thus possible to design the operating unit 2 and the striking device 1 or, in the application, the operating unit and the firearm 20, in which the striking device 1 is installed, as separate components. This further improves handling and eliminates any influence that the actuation of the operating unit 2 could have on the accuracy of the shot.

Is used for illustration purposes Figure 3 , which shows a shooter who holds the firearm 20 with built-in striking device 1 with electro-magnetic trigger unit 4 in the first hand and the control unit 2 in the second hand. The shooter can now use the first hand to accurately target the firearm 20 align and then only has to use the other hand to operate the actuating element 18 of the Operate control unit 2 in order to transmit the actuation signal 7 to the firearm 20 and thus trigger the shot.

Coming back to Figure 1 the structure of the operating unit 2 will be explained in more detail below. Due to the separate design of impact device 1 and operating unit 2, it is provided in the present exemplary embodiment that operating unit 2 comprises a housing 17 in which the electronic components of operating unit 2 are arranged. The aforementioned actuating element 18 is arranged on the housing 17 in such a way that it can easily be actuated with one hand.

In addition to the transmission device 5, the operating unit 2 comprises a second energy supply unit 9, which provides the electrical energy required to generate the actuation signal 7. In the present exemplary embodiment, the two energy supply units 8, 9 are designed as energy stores, for example as batteries or accumulators. An actuation switch 22, which is operatively connected to the actuation element 18, is provided in the present exemplary embodiment in order to interrupt or, preferably for a predefined period of time, to close a transmitter circuit comprising a transmission device 5 and a second energy supply source 9 in order to generate and transmit the actuation signal 7 . It goes without saying that this is only one of many equivalent possibilities for activating the transmission device 5, so it is of course also conceivable that the transmitter circuit is always closed and the actuating element 18 is connected directly to the transmission device 5 Generation and transmission of the actuation signal 7 interacts.

In order to improve the operational safety of the system and in particular to minimize the risk of an unintentional and / or unauthorized triggering of the triggering movement of the firing pin 3 or a firing of a shot in the case of application, there are various options Security aspects integrated into the system, which each work and can be used separately from one another.

The operating unit 2 has an unlocking element 19 which must be actuated or manipulated before the actuation signal 7 can be generated. It is both conceivable that the unlocking element 19 acts on a mechanical locking of the actuating element 18, so that the actuating element 18 cannot be moved without the unlocking element 19 having been actuated beforehand. On the other hand, it is also conceivable that the unlocking element 19 either acts on the transmitter circuit, closes it, for example, only when actuated, or acts directly on the transmitter device 5, the transmitter device 5 being by default in a non-ready state and only when the Unlocking element 19 is placed in a ready-to-send state. It would also be conceivable for the unlocking element 19 to be designed as a cap which conceals the actuation element 18 and is connected to the housing 17 in an articulated manner, which cap has to be opened in order to reach the actuation element 18.

Furthermore, the electromagnetic release unit 4 comprises a safety switch 16 which is arranged in the receiver circuit. The receiver circuit can be interrupted by means of the safety switch 16 in order to put the receiving device 6 in a state that is not ready to receive. The actuating signal 7 can only be received and the triggering movement of the firing pin 3 triggered when the receiver circuit is closed by the safety switch 16 and the receiving device 6 has thus been put into a ready-to-receive state. It is also conceivable that the safety switch 16 interacts directly with the receiving device 6 in order to put it into the ready-to-receive state. The non-ready-to-receive state is also to be understood as a state in which the actuation signal 7 is received, but the electromagnetic trigger unit 4 is not activated in order to effect the triggering movement.

Another possibility for securing the striking device is brought about by the security device 15, which blocks or releases the movement of the firing pin 3 per se and has the same functionality as a safety device of a conventional firearm. In the present exemplary embodiment, the safety device 15 comprises an actuatable safety lever 15a which, in a secured position, engages in a safety lug 15b of the firing pin 3 in order to block the triggering movement. Only when the safety lever 15a has been brought into an unlocked position and the safety lug 15b is free can the firing pin 3 run through the triggering movement. This, too, is merely an exemplary description of one of many equivalent safety devices 15.

With regard to the transmission of the actuation signal 7 between the transmitting device 5 and the receiving device 6, various safety precautions can be provided. On the one hand, the transmitting device 5 can comprise means for generating an identification code which can be clearly assigned to the operating unit 2 and which add this identification code to the actuation signal 7. The receiving device 6 accordingly comprises means for comparing the identification code of the received actuation signal 7 with a stored identification code of the associated operating unit 2. By generating the identification code and comparing it, it can be ensured in a simple manner that the electromagnetic release unit 4 only is activated when the actuation signal 7 comes from the associated operating unit 2.

A further safety precaution relates to the transmission of the actuation signal 7 itself and provides that the transmission device 5 has means for encrypting the actuation signal 7, for example by means of an encryption algorithm, and the receiving device 6 has means for decrypting the Has actuation signal 7. In this way, influencing or manipulation of the actuation signal 7 by an unauthorized third party can be prevented in a simple manner.

It is advantageous if the transmitting device 5 and / or the receiving device 6 each have a microprocessor or a microchip by means of which the aforementioned encryption and / or identification operations can be carried out.

As already mentioned at the outset, the present exemplary embodiment also includes, in addition to the electromagnetic release unit 4, a mechanical release unit 10, so that the impact device 1 can be activated either by operating the operating unit 2 via the electromagnetic release unit 4 or by operating the trigger 11 Via the mechanical trigger unit 10. This combination of the two trigger units 4.10 enables two different shot modes in the application: on the one hand, a shot can be triggered in a conventional manner by actuating the trigger 11; on the other hand, by actuating the operating unit 2 due to the previously described effects a shot can be fired with increased accuracy.

As in particular in Fig. 2 As can be seen, two separately actuatable firing pins 3, 12 are provided in the present exemplary embodiment: the firing pin 3, which, as described above, interacts with the electromagnetic trigger unit 4, and another firing pin 12, which interacts with the mechanical trigger unit 10. In order to be able to arrange the two firing pins 3.12 as space-saving as possible, one of the firing pins 3.12, in the present case the further firing pin 12, has a cavity along its longitudinal axis, through which cavity the firing pin 3 is guided. Alternatively, a parallel guidance of the two firing pins 3, 12 would also be conceivable. If the deduction is 11 actuated, only the further firing pin 12 performs the triggering movement by actuation by means of the mechanical triggering unit 10. Conversely, only the firing pin 3 carries out the triggering movement when the electromagnetic triggering unit 4 is activated by means of the operating unit 2.

Also in Fig. 2 it can be seen that the safety device 15 described above blocks both the triggering movement of the firing pin 3 and the triggering movement of the further firing pin 12, since the further firing pin 12 also has safety lugs 15b in which the safety lever 15a engages.

In alternative exemplary embodiments, not shown, it is also conceivable that the mechanical release unit 10 and the electromagnetic release unit 4 interact with the same firing pin 3. In this case it is advantageous if the striking device 1 has a selector switch by means of which one of the two triggering units 4, 10 can be activated and the other can be deactivated.

In alternative exemplary embodiments, not shown, it is also conceivable that the electromagnetic trigger unit 4 does not actively cause the triggering movement of the firing pin 3, as in the present case, but that the electromagnet 13 of the electromagnetic triggering unit 4 pushes the firing pin 3 against the firing pin 3 acting pre-tensioning force holds in the rest position. In particular, it can be provided that the firing pin 3 is preloaded by means of a spring and is held in the rest position by an electromagnet 13 designed as a holding magnet. As soon as the receiving device 6 receives the actuation signal 7 and activates the electromagnetic release unit 4, the electromagnet 13 is deactivated so that no more holding force acts on the firing pin 3 and this executes the release movement due to the pretensioning force. In In this case, the triggering movement is triggered by the electromagnetic triggering unit 4.
