Abstract

The holding housing (1) of the laser pulse transmitter has essentially the shape and size of the cartridge suitable for a weapon and can be inserted instead of this into the barrel or the cartridge bearing of a weapon. The holding housing (1) contains a sleeve (2) which is closed at both ends by means of holders (4,6). A laser collimator (28) is arranged at the front end and a switch (8) designed as piezoceramic (10) is arranged at the rear end. A printed circuitboard (34) is provided in the chamber (32) formed between the holders (4,6), a current source (36) being present on one side and a driver circuit (38) on the other side. Since the piezoceramic (10) serves only as a switch (8) and batteries (36) are provided as a current source, on the one hand a very small design and on the other hand a low striking force of the striking pin are possible. The laser pulse transmitter can thus also be designed for small-calibre weapons. <IMAGE>

Description

Die Erfindung betrifft einen Laser-Impulssender für eine Waffe gemäss Oberbegriff des Anspruches 1.The invention relates to a laser pulse transmitter for a weapon according to the preamble of claim 1.

Aus der US-PS 3 938 262 ist ein Laser-Impulssender der eingangs genannten Art bekannt. Als Schalter zum Auslösen des Laser-Impulssenders sowie als Stromquelle dient ein piezoelektrischer Wandler. Daraus ergeben sich die Nachteile, dass für eine ausreichende Stromversorgung der Wandler relativ gross sein muss und andererseits eine erhebliche Schlagkraft erforderlich ist. Die grosse Bauweise beschränkt den Laser-Impulssender auf Waffen grossen Kalibers. Die hohe Schlagkraft kann überdies zu einer Beschädigung des Impulssenders und/oder des Schlagbolzens und damit der Waffe führen.A laser pulse transmitter of the type mentioned is known from US Pat. No. 3,938,262. A piezoelectric converter serves as a switch for triggering the laser pulse transmitter and as a current source. This results in the disadvantages that the converter must be relatively large for an adequate power supply and, on the other hand, considerable impact is required. The large design limits the laser pulse transmitter to weapons of large caliber. The high impact can also damage the pulse transmitter and / or the firing pin and thus the weapon.

Aufgabe der Erfindung ist es, einen Laser-Impulssender so auszubilden, dass die erwähnten Nachteile vermieden werden.The object of the invention is to design a laser pulse transmitter so that the disadvantages mentioned are avoided.

Die gestellte Aufgabe wird durch die Merkmale des Anspruches 1 gelöst.The object is achieved by the features of claim 1.

Da der piezoelektrische Wandler nur als Schalter benutzt wird, genügen sehr kleine Stromstösse zur Auslösung des Schaltkreises und damit zum Aussenden des Laser-Signals. Der Wandler kann deshalb sehr klein gehalten und die Schlagkraft des Schlagbolzens reduziert bzw. entsprechend gedämpft werden. Dies führt wiederum zu einer Schonung des Laser-Impulssenders wie der Waffe. Durch die kleine Bauweise ist auch ein Einsatz in kleinkalibrigen Waffen möglich.Since the piezoelectric transducer is only used as a switch, very small current surges are sufficient to trigger the circuit and thus to send out the laser signal. The converter can therefore be kept very small and the impact force of the firing pin reduced or damped accordingly. This in turn leads to protection of the laser pulse transmitter and the weapon. Due to the small design, it can also be used in small-caliber weapons.

Vorteilhafte Ausgestaltungen des Laser-Impulssenders sind in den Ansprüchen 2 bis 10 beschrieben.Advantageous embodiments of the laser pulse transmitter are described in claims 2 to 10.

Für die Anordnung des piezoelektrischen Wandlers gibt es verschiedene Ausgestaltungsmöglichkeiten. Besonders vorteilhaft ist jedoch eine Ausbildung nach Anspruch 2 und die Weiterbildung nach Anspruch 3. Letztere verhindert besonders wirksam eine Beschädigung des piezoelektrischen Wandlers und eine zu hohe Spannung beim Auslösen durch den Schlagbolzen einer Waffe.There are various design options for the arrangement of the piezoelectric transducer. However, a design according to claim 2 and the development according to claim 3 are particularly advantageous. The latter particularly effectively prevents damage to the piezoelectric transducer and excessive voltage when triggered by the firing pin of a weapon.

Die Schaltung und deren Anordnung kann in verschiedener Form ausgebildet und in einer Hülse angeordnet sein. Eine sehr zweckmässige Lösung beschreibt Anspruch 4, da dann keine zusätzlichen mechanischen Haltevorrichtungen erforderlich sind, sondern die Printplatte im Zylinder der Hülse gehaltert ist. Gegebenenfalls können Batterien auch auf beiden Seiten der Printplatte angeordnet sein.The circuit and its arrangement can be designed in various forms and arranged in a sleeve. A very useful solution is described in claim 4, since then no additional mechanical holding devices are required, but the printed circuit board is held in the cylinder of the sleeve. If necessary, batteries can also be arranged on both sides of the printed circuit board.

Um die Treiberschaltung möglichst klein zu halten, ist es zweckmässig, sie nach Anspruch 5 auszugestalten. Eine noch kleinere Bauweise ermöglicht die Ausbildung nach Anspruch 6. Eine hohe Schussleistung bei geringstem Stromverbrauch ermöglicht eine Ausgestaltung nach Anspruch 7. Besonders vorteilhaft ist jedoch auch eine Weiterbildung nach Anspruch 8, die es einerseits ermöglicht, insbesondere auf lange Distanzen Fremdlicht auszuschalten und andererseits differenziertere Empfangsmöglichkeiten an der Zielscheibe gestattet.In order to keep the driver circuit as small as possible, it is expedient to design it according to claim 5. An even smaller construction enables the design according to claim 6. A high shot power with the lowest power consumption enables an embodiment according to claim 7. However, a further development according to claim 8 is particularly advantageous, which on the one hand makes it possible to switch off extraneous light, in particular over long distances, and on the other hand differentiated reception options allowed on the target.

Der Laser-Kollimator kann gemäss Anspruch 9 am vorderen Ende des Einsatzes angeordnet sein, wobei dies nur für Waffen eines bestimmten Kalibers möglich ist. Für Kleinkalibrigere Waffen ist die Ausbildung nach Anspruch 10 besonders geeignet.The laser collimator can be arranged according to claim 9 at the front end of the insert, this being possible only for weapons of a certain caliber. For small-caliber weapons, the training according to claim 10 is particularly suitable.

Der Laser-Impulssender-Einsatz kann für die verschiedensten Waffen ausgestaltet sein, d.h. die Form der jeweils erforderlichen Patrone aufweisen.The laser pulse transmitter insert can be designed for a wide variety of weapons, i.e. have the shape of the required cartridge.

Der in den Figuren 1 bis 3 dargestellte Laser-Impulssender weist ein Einsatz-Gehäuse in der Form der Patrone einer Waffe auf, das eine Hülse 2 mit einem vorderen Halter 4 und einem hinteren Halter 6 enthält. Der hintere Halter 6 ist mit der Hülse 2 einteilig ausgebildet und dient zur Aufnahme eines Schalters 8 des Laser-Impulssenders. Dieser enthält einen piezoelektrischen Wandler, vorzugsweise eine Piezokeramik 10 und ist in einer Ausnehmung 12 des Halters 6 gelagert. Hierzu ist die Piezokeramik 10 zwischen zwei Metallplatten 14 und 16 angeordnet, die jeweils einen Leiter 18 und 20 der Piezokeramik aufweisen. Die äussere Metallplatte 16 besteht vorzugsweise aus gehärtetem Stahl, um eine Beschädigung der Piezokeramik 10 durch den Schlagbolzen einer Waffe zu verhindern. Eine äussere Platte 22 dient zur Absicherung der Anordnung im hinteren Halter 6 der Hülse. Der vordere Halter 4 ist abnehmbar an der Hülse 2 angeordnet und mittels einer Stiftschraube 24 gesichert. Am vorderen Ende des Halters 4 trägt dieser in einer Ausnehmung 26 einen Laser-Kollimator. Die zum Anschluss des Laser-Kollimators 28 dienenden Leitungen 30 verlaufen durch den Halter 4.The laser pulse transmitter shown in FIGS. 1 to 3 has an insert housing in the form of the cartridge of a weapon, which contains a sleeve 2 with a front holder 4 and a rear holder 6. The rear holder 6 is formed in one piece with the sleeve 2 and serves to receive a switch 8 of the laser pulse transmitter. This contains a piezoelectric transducer, preferably a piezoceramic 10 and is mounted in a recess 12 in the holder 6. For this the piezoceramic 10 is arranged between two metal plates 14 and 16, each having a conductor 18 and 20 of the piezoceramic. The outer metal plate 16 is preferably made of hardened steel in order to prevent damage to the piezoceramic 10 by the firing pin of a weapon. An outer plate 22 serves to secure the arrangement in the rear holder 6 of the sleeve. The front holder 4 is removably arranged on the sleeve 2 and secured by means of a stud 24. At the front end of the holder 4, this carries a laser collimator in a recess 26. The lines 30 used to connect the laser collimator 28 run through the holder 4.

Zwischen den Haltern 4 und 6 ist eine Kammer 32 gebildet, in der eine Printplatte 34 angeordnet ist, deren Breite dem Innendurchmesser der Hülse 2 und deren Länge der Länge der Kammer 32 entspricht. Auf der einen Seite der Printplatte 34 ist eine Stromquelle 36 aus zwei Batterien angeordnet und auf der gegenüberliegenden Seite eine Treiberschaltung 38 für den Laser-Kollimator 28.Between the holders 4 and 6, a chamber 32 is formed, in which a printed circuit board 34 is arranged, the width of which corresponds to the inner diameter of the sleeve 2 and the length of which corresponds to the length of the chamber 32. A power source 36 consisting of two batteries is arranged on one side of the printed circuit board 34 and a driver circuit 38 for the laser collimator 28 on the opposite side.

Die Figur 4 zeigt das Schaltbild des Laser-Impulssenders, wobei mit Ausnahme der Bauteile: Piezokeramik 10, Laser-Kollimator 28 (Typ CQL75A/D 2,5 mW Philips), sowie die Stromquelle 36 (beispielsweise 1 oder 2 Lithium-Batterien BR 211, 3V, 5,4 mAh), alle übrigen Bauteile als SMD-Komponenten auf der Printplatte 34 enthalten sind. Dies betrifft insbesondere die IC-Komponenten 40, Transistoren 42, Widerstände 44 und Kondensatoren 46. Der Kondensator 46a liefert die zum Zünden des Laser-Kollimators 28 erforderliche höhere Stromstärke. Die der Printplatte zugeordneten Bauteile sind über Steckverbindungen 48 angeschlossen.FIG. 4 shows the circuit diagram of the laser pulse transmitter, with the exception of the components: piezoceramic 10, laser collimator 28 (type CQL75A / D 2.5 mW Philips), and the power source 36 (for example 1 or 2 lithium batteries BR 211 , 3V, 5.4 mAh), all other components are contained as SMD components on the printed circuit board 34. This applies in particular to the IC components 40, transistors 42, resistors 44 and capacitors 46. The capacitor 46a supplies the higher current intensity required to ignite the laser collimator 28. The components assigned to the printed circuit board are connected via plug connections 48.

Die Treiberschaltung ist so ausgelegt, dass sie beispielsweise einen Schussimpuls von 10 Mikrosekunden erzeugt. Mit dem gezeigten Laser-Impulssender können mehr als eine Million Schuss abgegeben werden.The driver circuit is designed such that it generates a shot pulse of 10 microseconds, for example. With the laser pulse transmitter shown, more than a million shots can be fired.

Im Gegensatz zum gezeigten Ausführungsbeispiel ist es auch noch möglich, den Laser-Impulssender so auszugestalten, dass der Schussimpuls moduliert ist, um insbesondere beim Schiessen auf grössere Distanz Fremdlichteinflüsse auszuschalten und/oder eine Zielscheibenvorrichtung zu betreiben, die modulierte Schussimpulse erfordert. Ein entsprechender Modulator 50 ist gestrichelt in der Schaltung gemäss Figur 4 angedeutet.In contrast to the exemplary embodiment shown, it is also possible to design the laser pulse transmitter in such a way that the shot pulse is modulated in order to switch off extraneous light influences, in particular when shooting at a greater distance, and / or to operate a target device which requires modulated shot pulses. A corresponding modulator 50 is indicated by dashed lines in the circuit according to FIG. 4.

In Abwandlung des gezeigten bzw. beschriebenen Ausführungsbeispieles ist es auch möglich, die als Stromquelle dienenden Batterien beidseits der Printplatte anzuordnen. Eine weitere Miniaturisierung der Treiberschaltung ist bei deren Ausbildung in Hybridtechnik möglich.In a modification of the exemplary embodiment shown or described, it is also possible to arrange the batteries serving as current sources on both sides of the printed circuit board. A further miniaturization of the driver circuit is possible when it is trained in hybrid technology.

Die Figur 5 zeigt einen weiteren vorteilhaften Schalter 52 für den Laser-Impulssender. Der Schalter enthält ein in eine Ausnehmung des Halters 6 der Hülse 2 einsetzbares Schaltergehäuse 54 aus Kunststoff, in das ein topfförmiger Deckel 56 aus Kunststoff eingesetzt ist, welcher eine zentrale Oeffnung 58 zur Aufnahme einer Stahlkugel 60 aufweist, auf die der Schlagbolzen der Waffe beim Abfeuern derselben auftrifft. Die Stahlkugel 60 stützt sich nach innen auf einem vorzugsweise vorgespannten elastischen Ring 62 ab, der auf einer Stahlplatte 64 aufliegt, unter der eine Piezokeramik 66 angeordnet ist, die sich nach innen auf einer weiteren Platte 68 abstützt. Beidseits der Piezokeramik 66 sind Kontaktscheiben 70,72 mit Lötfahnen 74,76 vorhanden, die nach dem Zurückbiegen die Verbindung zum Schaltkreis des Laser-Impulssenders herstellen. Durch diese Ausbildung des Schalters wird die Schlagenergie des Schlagbolzens so stark abgebremst, dass einerseits Beschädigungen des Schalter, insbesondere der Piezokeramik, sowie des Schlagbolzens und andererseits eine zu hohe Spannung der Piezokeramik verhindert werden.FIG. 5 shows a further advantageous switch 52 for the laser pulse transmitter. The switch contains a switch housing 54 made of plastic, which can be inserted into a recess of the holder 6 of the sleeve 2 and into which a pot-shaped cover 56 made of plastic is inserted, which has a central opening 58 for receiving a steel ball 60, onto which the firing pin of the weapon is fired the same strikes. The steel ball 60 is supported on the inside on a preferably prestressed elastic ring 62, which rests on a steel plate 64, under which a piezoceramic 66 is arranged, which is supported on the inside on a further plate 68. On both sides of the piezoceramic 66 there are contact disks 70, 72 with soldering lugs 74, 76 which, after bending back, establish the connection to the circuit of the laser pulse transmitter. Through this design of the switch The impact energy of the firing pin is braked so strongly that damage to the switch, in particular the piezoceramic, and the firing pin and, on the other hand, excessive tension of the piezoceramic are prevented.

Die Figur 6 zeigt einen weiteren Laser-Impulssender, der auf einer Seite des Gehäuses den in Figur 5 gezeigten Schalter 52 enthält. Das Gehäuse 78 bildet wiederum eine Kammer 80, in der anschliessend an den Schalter 52 eine Printplatte 82 mit Treiberschaltung und Batterie analog dem Beispiel der Figur 1 angeordnet sind. Die Printplatte 82 nimmt jedoch nur einen Abschnitt der Kammer 80 ein, wobei sich gegen das vordere Ende des Gehäuses ein Laser-Kollimator 84 an die Printplatte 82 anschliesst. Den vorderen Abschluss des Gehäuses 78 bildet ein Zentriereinsatz 86, der in den Lauf einer Waffe einsetzbar ist und zur Zentrierung des Laser-Impulssenders dient. Der Zentriereinsatz 86 enthält am vorderen Ende eine Lochblende 88, um den Laserstrahl zur Achse der Waffe auszurichten.FIG. 6 shows a further laser pulse transmitter which contains the switch 52 shown in FIG. 5 on one side of the housing. The housing 78 in turn forms a chamber 80 in which a printed circuit board 82 with a driver circuit and a battery analogous to the example in FIG. 1 are arranged after the switch 52. However, the printed circuit board 82 occupies only a portion of the chamber 80, a laser collimator 84 connecting to the printed circuit board 82 against the front end of the housing. The front end of the housing 78 is formed by a centering insert 86 which can be inserted into the barrel of a weapon and is used to center the laser pulse transmitter. The centering insert 86 contains a pinhole 88 at the front end to align the laser beam with the axis of the weapon.
