Abstract

The device has a sensor region (24.1,24.2) for detecting a state and a conductor arrangement (24.3) connected to the sensor region for transmitting the signal, whereby the sensor region and conductor arrangement are formed by a fiber-optic system (24), and a movable indicator (17) whose position corresponds to the detected state. The sensor region of the fiber optic system is protected by a shielding device (20). An Independent claim is also included for a firearm with an inventive device for detecting a state in a firearm chamber and transmitting a correlated signal.

Description

The invention relates to a device for a firearm Acquisition and transfer of an optical signal which has a state is correlated in a room, according to the preamble of claim 1, as well as a Firearm according to the preamble of claim 18.

On firearms, especially on semi-automatic and automatic firearms such as cannons are sensors in several places used to serve signals while using firearms to capture to monitor the firearms, especially when shooting. Specifically, the sensors capture signals that are related to states in monitoring rooms are correlated. In general, the sensors are Transmission devices connected to the detected signals to transfer. The transmitted signals are used for various purposes used; they can only be used by the operating personnel Provide information about the recorded status, but they can also be used in a Control chain or a control loop can be used, for example, a The sequence of functions within the scope of firing is controlled.

States to be detected can be positions of mechanical Weapon components that are, for example, only temporary and / or in different proportions of their own mass in the rooms to be monitored available. Examples include slide positions, locking positions, Clutch positions, trigger positions and drum positions called, however also filling states, e.g. from cartridge storage locations can be monitored in this way.

As examples of the utilization of the signals which the mentioned or describe other states are the direct change of one State of motion, i.e. initialization, change or termination a movement of a weapon part or the construction of a timing chain or one Called control loop. Firearms like cannons, for example on the one hand gas drive as self drive and on the other hand an electric drive for the Have ammunition feed, the gas drive and the electric drive work independently of one another and therefore ensure that the Firearm and its control linked by a control loop Need to become.

Traditionally, firearms have been used as sensors mechanical, inductive, capacitive or magnetic purposes Devices used, but especially for modern automatic weapons high cadence are not suitable. With such firearms, high abrupt firings occur Stresses and alternating stresses on high frequencies, which lead to sensitive parts of conventional construction such as that mentioned devices do not work properly and / or only one have a short lifespan. Particularly high The devices placed directly on the barrel are worn out subjected.

From US-5,425,299 and from US-5,735,070 are also Firearms known, the sensor devices with fiber optic systems exhibit. The disadvantage of this is that the sensitive area of fiber optic systems are not shielded so that they are even slight Soiling, as is usually the case in weapons, or not do not work reliably.

• eine Vorrichtung der eingangs genannten Art zu schaffen, welche die erwähnten Nachteile nicht aufweist und mit welcher auch bei Waffen hoher Kadenz eine lange Lebensdauer bei präziser Funktion erreicht werden kann; und
• eine verbesserte Feuerwaffe der eingangs genannten Art vorzuschlagen.

It is therefore an object of the invention

• to create a device of the type mentioned, which does not have the disadvantages mentioned and with which a long service life with precise function can be achieved even with weapons with high cadence; and
• to propose an improved firearm of the type mentioned at the beginning.

• für die Vorrichtung durch die kennzeichnenden Merkmale des Anspruchs 1; und
• für die Feuerwaffe durch die kennzeichnenden Merkmale des Anspruchs 19.

This object is achieved according to the invention

• for the device by the characterizing features of claim 1; and
• for the firearm by the characterizing features of claim 19.

Preferred developments of the invention are given by the respective dependent claims 2 to 17 or 19 to 30 defined.

With the invention, highly sensitive precision engineering for an object that is high and fluctuating mechanical Is exposed to loads, namely for a firearm also high cadence, to make it fit.

The device according to the invention or the device with it equipped firearm instead of conventional mechanical, inductive, capacitive or magnetic, electrical devices a fiber optic system on which is resistant to impact stress and Vibration has proven. Resistance to shock and vibration will among other things achieved by bundling for the fiber optic system combined fibers in a number of, for example, up to 100 or up to 200 Fibers are used, each fiber having a diameter of for example, has 12 µm.

For the conditions to be recorded in the room to be monitored are generally scannable states. Among the too Detectable, scannable states are supposed to be both the location of a material Element as well as a pressure in a pressure vessel can be understood, whereby a material element immediately and a pressure in a pressure vessel a sliding piston can be scanned.

Fiber optic systems only work correctly when they are not are impaired. Dreaded impairments are less mechanical damage as dirt. Firearms now exist but often a considerable risk of pollution; the fiber optic systems it can deal with matter of any kind like dust, soot, Liquids such as lubricants such as graphite grease and vapors are whole generally fogged up in solid and liquid form. Around to avoid a dysfunction as a result of such impairments Fiber optic systems are shielded by at least their sensor area a shielding device is protected, either by a suitable one Wise arranged wall or a chamber can be.

In order to avoid misunderstandings, it is expressly pointed out pointed out that such a chamber is not the too monitoring room in which a condition by the new device should be determined, acts, and also not the above Pressure vessel, but around an area shielded from contamination, in which at least the sensor area of the fiber optic system is arranged is.

The condition to be recorded in the room to be monitored shows a Indicator that directly or indirectly senses the condition to be recorded and the position of which arises as a function of the state. The location of the indicator is recognized by the sensor area of the fiber optic system.

There are basically two optical methods for recording the Location of the indicator in question. In the first method, the respective location of the Indicator captured directly by the sensor area of the fiber optic system Forms a light barrier into which the indicator protrudes in certain positions; the Fiber optic system generates a signal when the indicator has a special location occupies; the indicator can either be compact and in interrupt the otherwise sensible light beam in the special position, or the Indicator can have a breakthrough through which the otherwise interrupted one Beam of light goes through. In the second method of detecting the location of the A reflection effect is used.

For the training, arrangement and mode of operation of the indicator there are different variants, the preferred ones below to be discribed.

The position of the indicator is determined by a sensor that in turn senses the condition in the room to be monitored, in general, by mechanically scanning it. The indicator and the sensor can form different components that move at least temporarily in solidarity, or they can be in one piece. The sensor therefore probes the one to be detected State in the room to be monitored, which means its location and thus the location of the indicator are determined. The sensor area of the fiber optic system recognizes, as already mentioned, the position of the indicator.

The chamber in which at least the sensor area of the Fiber optic system is not a completely complete one Capsule, but it has an inlet or passage through which the Indicator protrudes into the chamber.

It is for reliable operation of the device it is crucial that this inlet or outlet is designed in a suitable manner is. Firstly, to prevent the interior of the chamber from doing so is contaminated that the sensor area of the fiber optic system is no longer works flawlessly; the inlet must therefore have a sealing arrangement be provided. On the other hand, a reset of the sensor in the Generally going on under the force of a return spring, frictionless or at least as little friction as possible; the sealing arrangement must therefore be designed so that the resetting of the sensor does not occur Frictional forces are hindered.

To the signals captured by the fiber optic system, which the Describe the state in the room to be monitored, to utilize it advantageous to convert these optical signals into electrical signals for what an opto / electrical converter device can be provided. It can yourself with this converter device and possibly with those connected to it Devices are those that are more sensitive to shock and vibration than that Fiber optic system, but this can be accepted here because this Devices can easily be outside those areas of the firearm be arranged in which the particularly high blow and Vibration loads occur.

Those sensed by the fiber optic system as described above and transferred signals which are a function of the position of the sensor or the indicator and thus a function of what is to be recorded Conditions in the room to be monitored are in general to some extent, digital 'or qualitative signals; for example indicate such signals whether a component of the firearm is a particular one Position or not, or whether a particular cartridge storage location with a Cartridge is occupied or not. In certain cases it is advantageous to use the The condition in the room to be monitored can also be quantified. In a An advantageous further development of the device according to the invention is this Fiber optic system designed so that signals are also recorded and transferred can be the more accurate information in the manner of quantitative Include signals.

For example, at least one further sensor or at least one further indicator can be provided, which is associated with a further one Interact sensor area of the fiber optic system. Such an arrangement can be used in different ways. On the one hand, if the monitoring room is, for example, a cartridge depot, not only determine whether this cartridge storage location is occupied by a cartridge or not, but it can qualitatively also the length and thus the type of in the Cartridge location cartridge can be detected. On the other hand, it can Arrangement can also be used as a double safety device.

The amount of pressure in a pressure vessel can also be quantitative be recorded by the location of a corresponding indicator by a or multiple sensor areas can be detected.

Precise information about the condition to be recorded in the monitoring space can also be obtained if the indicator is in different contiguous areas of markings, for example Barcodes, of which, depending on the position of the indicator, one or other marking can be read by the fiber optic system.

Fig. 3

a diagram of a circuit in which the links of the devices according to the invention are shown in FIGS. 2A to 2F.

1A to 1E serve to explain the principle of the invention. 1A shows a room 10 to be monitored, which is not in one shown weapon in a shock and vibration affected area S located. In space 10 there is a cam wheel 12 with four cams 12.1 to 12.4 arranged, which is rotatable about an axis 14, which in FIG. 1 as point 14 appears. In the present case, the angular position of the cam wheel 12 is considered denotes a state to be detected in space 10. A mechanical sensor 16 has a sensor part 16.1, which is in each of its possible positions in the room 10 is located and the cam wheel 12 touches on its contour. The mechanical Sensor 16 is on the cam wheel 12 by means of a spring device 18 biased. A second sensor part 16.2 of the mechanical sensor 16 protrudes at least in the uppermost position that the mechanical sensor 16 occupy can, through an inlet 20.1 in a chamber 20, which is a shielding device for a fiber optic system 24 forms. The second sensor part 16.2 forms one Indicator 17.

A sealing device 20.2 is used to gaseous, liquid and to keep solid matter away from the chamber 20 which is in the chamber 20 arranged devices could impair their functions. Because the volumes are generally small, there is generally no condensation caused problem. The sealing device 20.2 aims for a full sealing but at the same time smooth or at least very low friction mutual contact of two moving relative to each other, in General cylindrical jacket surfaces.

Preferably one of these surfaces is covered with a Seal arrangement provided and the other of these surfaces with the best Provide surface smoothness. One surface or the sealing arrangement 20.2 can have sealing compounds, O-rings or Teflon sealing rings; the other area can be, for example, a finely polished metallic surface.

The indicator 17 can, at least in the area with which it is moves in the passage 20.1, a diameter of about 4 mm to about 15 mm have. The radial thickness of a ring, e.g. made of Teflon, the sealing compound suitable, can be about 0.5 mm and its axial width about 1mm. The Plated surface can be of 3M quality. These numbers are only to be understood as examples and in no way restrictive.

The mechanical sensor 16 protrudes in that shown in FIG. 1A Position so far in the chamber 20 that its second sensor part 16.2 or the indicator 17 a light beam 22 of a light barrier 24.1, 24.2 interrupts which light barrier the sensor area of the fiber optic system 24 forms. Like the room 10, the chamber 20 is also in the area A of the weapon affected by shock and vibration. The fiber optic system 24 is designed such that it provides an optical signal which directly from the position of the indicator 17 or the sensor 16 and indirectly dependent on the angular position of the cam wheel 12 and therefore with the mechanical state in the room 10 to be monitored is correlated. The feeler 1A is then in its uppermost position, if that Cam wheel 12 assumes a position in which two opposing cams, e.g. through the cams 12.1 and 12.3 on a vertical connecting straight line the point 14 and the other two cams 12.2 and 12.4 on one horizontal connecting straight line through point 14. A The conductor arrangement 24.3 of the fiber optic system 24 is out of the chamber 20 led out and coupled to an opto / electronic converter 26, which is used by the sensor area or light barrier 24.1, 24.2 of the fiber optic system 24 and detected by the conductor area of the fiber optic system 24 convert optical signal transmitted into an electrical signal. The electrical signal is sent via a line 27 to a computer unit 28 Provided, which is designed to this electrical signal recycle.

The opto / electrical converter 26 and the computer unit 28 are located itself in an area P of the weapon or a weapon system to which the weapon belongs, which does not shock or is less severe than area A is not affected by vibration or in which it is at least possible provided damping devices to provide the effects of Impacts and vibrations on the individual described and possibly on others Reduce devices.

1B shows another embodiment of the device of the invention, in which the sensor area of the fiber optic system 24 is also formed by a light barrier 24.1, 24.2. The indicator 17 is like this trained and arranged that in most of his positions he Light beam 22 from the light barrier 24.1, 24.2 of the fiber optic system 24 interrupts. The indicator 17 has a breakthrough 17.1; in a special Location which corresponds to a special condition in the room to be monitored 10 corresponds, the indicator 17 is in a position in which its breakthrough 17.1 the light beam 22 of the light barrier 24.1, 24.2 of the fiber optic system 24 clears the way.

Another embodiment of the new device is shown in Fig. 1C. The light barrier 24.1, 24.2 is designed here so that its the two elements are not in alignment but cross or corner to each other are arranged. The indicator 17 has two bolt-shaped indicator parts 17.2 on, each one as a partial reflection surface of a reflection surface 17.3 acting end area. In a special position of the two-part indicator 17, which corresponds to a special condition in the room 10 to be monitored, the reflection surfaces 17.3 cooperate so that the light beam 22 Light barrier 24.1, 24.2 from one element 24.1 of the light barrier to other element 24.2 of the light barrier is deflected, as is the case with the dotted line is indicated.

1D shows yet another embodiment of the new one Device in which the indicator 17 is designed to have several Indicator areas 17.10, 17.11, 17.12. Each of the indicator areas 17.10, 17.11, 17.12 has a marking which is defined by the sensor area 24.1 of the fiber optic system 24 can be seen. This allows the condition in monitoring room 10 quantify, either by the Markings are different and from the sensor area of the fiber optic system 24 can be recognized or read, or by counting the markings become. Furthermore, it is possible to link the time measurement to the Speed of a change in the state in the room to be monitored 10 determined by the number of marks recognized per unit of time is determined. Instead of detectable or readable markings, the Indicator 17 also have several breakthroughs, which in a suitable Position the passage of an otherwise interrupted light beam from a light barrier allow.

1E shows a further exemplary embodiment of a device according to the invention, which the sensor 16 or indicator 17 and that Fiber optic system 24 with a light barrier 24.1, 24.2 Has sensor area. In addition there are a second sensor 116 respectively Indicator 117 and a second light barrier 124.1, 124.2 as the second Sensor area provided. The room 10 to be monitored is one Cartridge storage location, and the condition to be monitored is the presence a cartridge 100. Were neither in the area of the first sensor 16 or Indicator 17 still in the area of the second sensor 116 or indicator Section of a cartridge in the cartridge chamber, so none of the Light barriers 24.1, 24.2 or 124.1, 124.2 the associated Record indicator 17 or 117. There is cartridge 100 completely in the cartridge storage location, as recorded in Fig. 1E, the Light barrier 24.1, 24.2 both indicator 17 and indicator 117.

An automatic firearm 1 is shown in detail in FIG a gun barrel 2 shown. The firearm 1 has several of the Devices according to the invention, each of which is used for one to monitor a specific room and the current state of the room to capture. The locations at which the devices are arranged are through Cut lines A-A, B-B, C-C, D-D, E-E and F-F designated.

Figure 2A shows section A-A of Figure 2, with one of the devices according to the invention, in which the condition to be detected is the locking or Unlocking the gun barrel 2 is. 2AA shows the section IIA-IIA of Fig. 2A. In the locked state of the barrel 2 there are two Locking elements 30 in the position shown in Fig. 2A, from which they unlocked state are shifted to the left. The indicator 17 is here formed in two parts and has two bolt-like indicator parts 17.2, which in an opening 32 of a body 34 are slidably disposed. With theirs from the opening 32 projecting ends, the indicator parts 17.2 engage in grooves 31 of the locking elements 30 as long as the locking elements 30 in the locking position. If there is no lock, they are the ones Locking elements from their position shown in Fig. 2A to the left postponed, which has the consequence that the indicator parts 17.2 in Move opening 32, first to the inside of opening 32 and, upon further displacement of the locking elements 30, under the force of Springs 36 out of the opening 32. Correct locking is only then present when the locking elements 30 and thus the Indicator parts 17.2 are in the position shown in FIG. 2A.

In the present exemplary embodiment according to FIG. 2A, the position of the indicator 17 or the indicator parts 17.2 not directly by the Sensor area 24.1, 24.2 of the fiber optic system 24 is detected, but it is a mirror surface or reflection surface 17.3 used, with the help of Sensor area 24.1, 24.2 of the fiber optic system 24 recognizes that the Interlock is present. The mirror surface or reflection surface is 17.3 continuous and flat, and as shown in Fig. 2AA, it consists of two mutually displaceable partial reflection surfaces, which on each other opposite inner ends of the indicator parts 17.1 are formed. This The inner ends of the indicator parts 17.1 are not circular in cross-section but only quarter-circle-shaped, and they are arranged in a complementary way so that they are move in the same length range of the recess 32 when locked to let; a semicircle of the cross-sectional area of the recess 32 occupied by the two inner ends of the indicator parts 17.1. The rest Semicircle of the cross-sectional area of the recess 32 remains empty and forms one Space for the beam 22 of the light barrier 24.1, 24.2, both of which Light barrier units are arranged in a corner in this case. Only in complete or secure locking state, that is, if the Inner ends of the indicator parts 17.1 the continuous reflection surface 17.2 form, the beam of the light barrier 22 can be reflected and reflected by the fiber optic system 24 generates the signal corresponding to the locked state become.

The locking status is therefore checked twice. The Fiber optic system 24 continues in the conductor arrangement 24.3. The Operation of the device according to FIG. 2A within a weapon control can be seen from Fig. 3, where it is labeled A.

It should be noted that the principle of Reflection of the beam of the light barrier can also be used in another way can, for example for a simple acquisition or verification of a State. It is not necessary for the reflection surface to consist of two partial surfaces is composed, it can be a single surface or more than two partial surfaces have, is flat, and it does not necessarily have to be continuous his. that the elements of the light barrier are below 90 °. Furthermore, the Both elements of the light barrier are also different than under 90 °, that is other than exactly corner. It is only essential that when entering of a certain state, possibly several states, in the to be monitored Space the reflection surface is arranged relative to the light barrier so that a Reflection takes place or an ongoing reflection is prevented, so that a corresponding signal is generated.

Fig. 2B shows section B-B of Fig. 2, with one of the devices according to the invention, in which the condition to be monitored is the position of a Slider 40 is. The slider 40 acts as a clock for several processes and to a certain extent forms a pacemaker for the firearm 1. Fig. 2B shows the slide 40 in its front position. A slide part 42 is in Contact with a stylus that forms probe 16. With one rotation Drum 3 of the firearm 1, the slide 40 moves in the direction of Longitudinal axis of the barrel 2. Here, the slide member 42 moves the Stylus or sensor 16. The part of the sensor on which the indicator 17 is formed, protrudes through the with a sealing device 20.2 provided passage 20.1 in the chamber 20. In the chamber 20 are the Sensor area of the fiber optic system 24 forming light barrier 24.1, 24.2 and the adjoining section of the conductor arrangement 24.3 of the fiber optic system 24 arranged. The mode of operation of the device according to FIG. 2B within a weapon control can be seen from FIG. 3, where it is designated B.

Fig. 2C shows the section C-C of Fig. 2 with a third arrangement one of the devices according to the invention. Under that to be monitored The condition here is the occupation of a cartridge storage location 50 of the drum 3 understood a cartridge. The arrangement shown in FIG. 2C is concerned around the cartridge storage location 50 in the fire position, and a position is shown in which this cartridge storage location 50 is empty. A cartridge detection pen, which forms the sensor 16, senses whether the cartridge storage location 50 with a cartridge is busy. That projecting into the cartridge storage area 50, which is empty according to FIG. 2C Sensor part 16.1 would be radially removed from the drum 3 by a cartridge, in FIG. 2C so pushed down. The one opposite the sensor part 16.1 Sensor part forms the indicator 17 and protrudes into the chamber 20. In the chamber 20 are also the ones that form the sensor area of the fiber optic system 24 Light barrier 24.1, 24.2 and the adjoining section of the conductor arrangement 24.3 of the fiber optic system 24 arranged. The operation of the device 2C within a weapon control is from FIG. 3, where it with C is indicated.

Fig. 2D shows the section D-D of Fig. 2, with a fourth Arrangement of one of the devices according to the invention, with a redundant Arrangement. Under the condition to be monitored, the position of a Knitting pin 60 understood. With this arrangement, the sensor area does not the position of the active bolt 60 itself, but the position of a signal bolt determined, the signal bolt playing the role of the indicator 17 and is arranged axially parallel to the knitting pin 60. The active bolt 60 has a Elongated hole 61, and it is with the signal bolt or indicator 17 for one translational movement can be coupled in terms of movement in the axial direction, with the help of an elongated hole 61 and coupling tabs 62, 64.

The signal bolt or indicator 17 is formed here and arranged that he with the first light barrier 24.1, 24.2 and the sensor area and with a second light barrier 124.1, 124.2 or a further sensor area of the fiber optic system 24 interacts. For this purpose, the signal bolt or indicator 17 has two Openings 17.1, 17.101 running transversely to its longitudinal direction. Is the Signal bolt or indicator 17 arranged as shown in Fig. 2D, the beam 22 of the light barrier 24.1, 14.2 passes through the opening 17.1 and is therefore not interrupted. At the same time, beam 122 becomes the Light barrier 124.1, 124.2 through the signal bolt or indicator 17 interrupted because the second breakthrough 17.1 is not in the way of this beam 122 is located.

The circuit is such that the signal from the light barrier 24.1, 24.2 corresponds to a position of the signal bolt or indicator 17, which indicates whether the firing pin is secured or unlocked, the interrupted beam 122 of the light barrier 124.1, 124.2 of a position of the signal bolt or indicator 17 corresponds, which indicates that the active bolt or ignition pin 60 is secured. Conversely, an interrupted light beam 22 from the light barrier 24.1, 24.2 and an uninterrupted light beam 122 from the light barrier 124.1, 124.2 indicate that the active bolt or ignition pin 60 is unlocked.

The state to be determined in the room 10 to be monitored and is therefore recorded in two ways. It is obvious that the circuit can also be reversed. 2A or their Operation is shown in Fig. 3, where it is designated D1 and D2. It it should be mentioned that with a different circuit but with the same Indicators and the same sensor area of the fiber optic system instead of one redundant arrangement also a simultaneously acting Double fuse arrangement can be realized.

Fig. 2E shows the section E-E of Fig. 2 with a fifth arrangement the device according to the invention. Under the condition to be monitored understood here the position of a gear coupling 70. There is also one here double detection of the state by the clutch position ON and Coupling position OFF can be monitored. A movable fork part 72 gives its position the position of the clutch 70. The pin forms the sensor 16 one end of which the indicator 17 is formed. The location of the pin 72 or the indicator 17, similar to that with reference to FIG. 2D described, detected by two light barriers. 2E further shows one additional monitoring device for the trigger, which is not with a Fiber optic system but is realized with a solenoid. The mode of action The device according to FIG. 2E within a weapon control is from FIG. 3 can be seen where the device realized with the fiber optic system 24 with E1 and E2 while the one realized with the solenoid Monitoring device is designated by G.

Fig. 2F shows in section F-F a sixth arrangement of one of the Devices according to the invention. Under the condition to be monitored here understood the promotion of ammunition in a certain area.
