Description

Die Erfindung betrifft eine an einem Waffenrohr einer großkalibrigen Waffe, insbesondere eines Granatwerfers, befestigbare Vorrichtung insbesondere zur Ermittlung der Neigung des Waffenrohres beim Richten oder dergleichen. Des Weiteren kann auch eine Verkantung ermittelt werden.The invention relates to a device on a gun barrel of a large caliber weapon, in particular a grenade launcher, fastenable device, in particular for determining the inclination of the weapon barrel when straightening or the like. Furthermore, a tilt can also be determined.

Das Richten von (Kommando-) Mörsern muss schnell, genau und robust sein. Im Wesentlichen finden dazu zwei Varianten Anwendung. So kann das Höhenrichten von Granatwerfern (Mörsern) beispielsweise dadurch erfolgen, dass im Mündungsbereich des Waffenrohres eine auf das Ziel ausrichtbare Zieloptik befestigt wird. Je nach Entfernung zum Ziel wird der Erhöhungswinkel als Winkel zur Abschussachse definiert. Nach dem Ausrichten der Optik auf das Ziel erfolgt dann die Erhöhung des Waffenrohres mittels einer Richtmaschine, wobei eine an der Zieloptik befindliche Libelle (Wasserwaage) in die Waagerechte gebracht wird. Dieses Richtverfahren ist zwar genau, aber relativ zeitaufwendig. Zum Höhenrichten eines Granatwerfers ist es ebenfalls bekannt, eine an dem Waffenrohr befestigte Schnur (oder ein Band) definierter Länge zu verwenden, welches mit Markierungen zur Bestimmung eines Dreieckes versehen ist. Sofern der Abschusswinkel bekannt ist, kann ein Höhenrichten des Waffenrohres durch entsprechende Festlegung der Seitenlängen des Dreieckes erfolgen. Mit diesem Verfahren kann der erforderliche Abschusswinkel auch durch eine an dem Waffenrohr nicht zu befestigende Einrichtung ermittelt (oder lediglich geschätzt) werden, doch ist das Richtverfahren selbst sehr ungenau.Judging (commando) mortars must be fast, accurate and robust. In essence, two variants are used. Thus, the leveling of grenade launchers (mortars), for example, by the fact that in the mouth area of the gun barrel to the target alignable target optics is attached. Depending on the distance to the target, the elevation angle is defined as the angle to the firing axis. After aligning the optics to the target then the increase of the gun barrel is done by means of a leveler, with a dragonfly located on the target optics (spirit level) is brought into the horizontal. This straightening process is accurate but relatively time consuming. For leveling a grenade launcher, it is also known to use a line attached to the gun barrel (or a band) of defined length, which is provided with markings for determining a triangle. If the launching angle is known, a height adjustment of the weapon barrel can be done by appropriately setting the side lengths of the triangle. With this method, the required launch angle can also be determined (or merely estimated) by a device not to be fastened to the weapon barrel, but the straightening process itself is very inaccurate.

Die vorhandenen Lösungen weisen somit eine aufwändige Bedienung, schlechte Ablesbarkeit mit einer damit verbundenen Ungenauigkeit sowie einen sperrigen Transport auf.The existing solutions thus have a complex operation, poor readability with an associated inaccuracy and a bulky transport.

Aus der EP 0 190 549 A1 ist eine Richteinrichtung mit Flüssigkeitsspiegel für eine Geschosswaffe bekannt. Diese Einrichtung besteht im Wesentlichen aus einem am Waffenrohr lösbar, lagefest etc. einbindbaren Behälter, der mit einer gering netzenden Flüssigkeit zum Teil befüllt ist. Der gegebenenfalls zum Teil mit mindestens einer Flüssigkeit gefüllter Behälter parallel zur Waffenrohrachse und mit dem Waffenrohr und parallel zur durch die Rohrachse gehende vertikalen Höhenrichtebene ausrichtbar. Der in etwa ring- bzw. schlauchwaageartige Behälter weist eine transparente Wandung auf, an der die horizontale Oberfläche bzw. Phasengrenze der Flüssigkeit ablesbar ist. Daraus ablesbar sind eine Höhenricht- bzw. Schussweiten- Skala. Eine Verkantung des Waffenrohres wird durch Schrägstehen der Skala in Relation zum Spiegel der Flüssigkeit angezeigt.From the EP 0 190 549 A1 is a liquid level straightener for a bullet weapon known.

The optionally partially filled with at least one liquid container aligned parallel to the weapon barrel axis and with the weapon barrel and parallel to the horizontal axis passing through the vertical plane of elevation. The approximately annular or hose-like container has a transparent wall, on which the horizontal surface or phase boundary of the liquid can be read. It can be read from a scale or shot range scale. Canting of the barrel is indicated by skewing the scale in relation to the level of the liquid.

Die WO 82/01413 A1 offenbart eine Vorrichtung gemäss dem Oberbegriff des Anspruchs 1. Es beschreibt einen Neigungsmesser mit kommunizierenden Röhren und einem Beobachtungsfenster für den Spiegel einer Flüssigkeit. Das Beobachtungsfenster ist mit einer Skala versehen zum Ablesen der Höhe des Flüssigkeitsspiegels. Diese Skala ist als Zielvorrichtung eines Geschützes mit Anzeigen entsprechend der Reichweite versehen, wobei diese Reichweite in direkter Beziehung zur Neigung des Rohrs steht. Alternative Anwendungen sind die Darstellung der Neigung eines Kranauslegers oder des Auslegers einer Baumaschine vom Fahrerhaus aus etc.The WO 82/01413 A1 discloses a device according to the preamble of claim 1. It describes an inclinometer with communicating tubes and an observation window for the level of a liquid. The observation window is provided with a scale for reading the height of the liquid level. This scale is provided as a target device of a gun with displays according to the range, which range is directly related to the inclination of the tube. Alternative applications are the representation of the inclination of a crane jib or the boom of a construction machine from the cab etc.

Mit der EP 0 258 176 A1 wird ein Visier an einer Feuerwaffe offenbart, das als einen umlaufender Ringraum ausgebildet ist, dessen axiale Höhe von einem zur Beobachtung des Flüssigkeitsniveaus im Ringraum vorgesehenen Fenster zur gegenüberliegenden Seite abnimmt.With the EP 0 258 176 A1 discloses a visor on a firearm, which is designed as a circumferential annular space whose axial height decreases from one provided for observation of the liquid level in the annulus window to the opposite side.

Der Erfindung liegt die Aufgabe zugrunde, die Idee eines Schlauchwaagemesssystems aufgreifend, eine Vorrichtung anzugeben, mittels welcher beim Richten einer Waffe, insbesondere eines Granatwerfers, der vorgegebene Neigungswinkel des Waffenrohres genau eingestellt werden kann, wobei eine gute Ablesbarkeit des jeweiligen Neigungswinkels und zusätzlich der jeweiligen Verkantung sichergestellt werden soll.The invention is based on the object, the idea of a Schlauchwaagemesssystems taking up, to provide a device by means of which when straightening a weapon, in particular a grenade launcher, the predetermined angle of inclination of the gun barrel can be accurately adjusted, with a good readability of the respective inclination angle and in addition to the respective canting should be ensured.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche. Die Erfindung beruht im Wesentlichen auf dem Gedanken, dass die Vorrichtung mindestens ein einem Schlauchwaagemesssystem (nach dem Schlauchprinzip arbeitend) entsprechendes Messsystem umfasst, welches aus zwei beabstandeten, sich in axialer Richtung des Waffenrohres erstreckenden, rohrförmigen Teilen besteht, die, in Schussrichtung des Waffenrohres gesehen, ober- und unterseitig miteinander verbunden sind. Dabei sind die beiden kommunizierenden rohrförmigen Teile des Meßsystems teilweise mit einer ersten Flüssigkeit gefüllt, wobei mindestens eines der beiden rohrförmigen Teile einen durchsichtigen Bereich zur Beobachtung der Lage des Flüssigkeitsspiegels aufweist, der an einer Messskala abgelesen werden kann.This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims. Essentially, the invention is based on the idea that the device comprises at least one measuring system which operates according to the hose principle and which consists of two spaced-apart tubular parts extending in the axial direction of the weapon barrel, viewed in the direction of firing of the weapon barrel , are connected to each other on the top and bottom. The two communicating tubular parts of the measuring system are partially filled with a first liquid, wherein at least one of the two tubular parts has a transparent region for observing the position of the liquid level, which can be read on a measuring scale.

Vorzugsweise ist die erfindungsgemäße Vorrichtung derart ausgebildet, dass zum Höhenrichten einer mit der Vorrichtung verbundenen Waffe die beiden rohrförmigen Teile des Messsystems in der Rohrerhöhungsebene der Waffe oder in einer parallel zu dieser befindlichen Ebene voneinander beabstandbar anordbar sind.Preferably, the device according to the invention is designed such that, for height adjustment of a weapon connected to the device, the two tubular parts of the measuring system can be spaced apart from one another in the tube elevation plane of the weapon or in a plane parallel thereto.

Die erfindungsgemäße Vorrichtung weist unter anderem den Vorteil auf, dass die durch das durchsichtige rohrförmige Teil des Messsystems gewählte Anzeigeneinrichtung relativ lang gewählt werden kann, sodass sich gegenüber bekannten Anzeigeneinrichtungen eine höhere Genauigkeit ergibt und die Anzeige überdies schnell ablesbar ist.The device according to the invention has, inter alia, the advantage that the display device selected by the transparent tubular part of the measuring system can be selected to be relatively long, so that a higher accuracy results compared to known display devices and the display can also be read quickly.

Außerdem ist die Anzeige unabhängig von der Neigung des Untergrunds oder der Lage des verwendeten Fahrzeuges.In addition, the display is independent of the inclination of the ground or the location of the vehicle used.

Die rohrförmigen Teile des Messsystems können mit einer selbstleuchtenden Flüssigkeit gefüllt sein, die auch ein Ablesen des Flüssigkeitsspiegels bei Dunkelheit ermöglicht. Auch eine externe Beleuchtung der Flüssigkeit ist möglich.The tubular parts of the measuring system can be filled with a self-luminous liquid, which also allows reading of the liquid level in the dark. External lighting of the liquid is also possible.

In den rohrförmigen Teilen des Messsystems können sich eine erste Flüssigkeit und ein Gas (in der Regel Luft) oder zwei Flüssigkeiten von unterschiedlicher Dichte, die sich nicht mischen und die gefärbt sein können, befinden.In the tubular parts of the measuring system may be a first liquid and a gas (usually air) or two liquids of different density, which can be do not mix and may be colored.

Die Anzeigeempfindlichkeit der erfindungsgemäßen Vorrichtung ist von dem Abstand und dem Durchmesserverhältnis der beiden rohrförmigen Teile abhängig, sodass durch Verwendung unterschiedlicher Rohrdurchmesser die Anzeigeempfindlichkeit der Vorrichtung gesteigert werden kann. Zudem kann über ein gewölbt ausgebildetes, rohrförmiges Teil in entsprechenden Bereichen eine erforderliche Erhöhung der Anzeigengenauigkeit erreicht werden.The display sensitivity of the device according to the invention is dependent on the distance and the diameter ratio of the two tubular parts, so that by using different pipe diameters, the display sensitivity of the device can be increased. In addition, a required increase in display accuracy can be achieved by means of a domed, tubular part in corresponding areas.

Bei den beiden rohrförmigen Teilen sowie bei den die rohrförmigen Teile verbindenden Teilen des Messsystems kann es sich sowohl um schlauchförmige Gummi- und/oder Kunststoffteile als auch um Metall- und/oder Glasrähren handeln.The two tubular parts as well as the parts of the measuring system which connect the tubular parts may be tubular rubber and / or plastic parts as well as metal and / or glass ferrules.

Bei einer bevorzugten Ausführungsform der Erfindung umfasst die Vorrichtung ein rohrförmiges Gehäuse, welches bei der bestimmungsgemäßen Verwendung der Vorrichtung den mündungsseitigen Bereich des Waffenrohres des Granatwerfers umschließt. An diesem Gehäuse sind sowohl die rohrförmigen Teile und deren Verbindungsteile als auch die Messskala angeordnet.In a preferred embodiment of the invention, the device comprises a tubular housing, which encloses the mouth-side region of the gun barrel of the grenade launcher in the intended use of the device. On this housing, both the tubular parts and their connecting parts and the measuring scale are arranged.

Ein Verkantungsausgleich des Waffenrohres beim Richten kann mit Hilfe einer an dem Gehäuse angeordneten Libelle erfolgen.A tilt compensation of the gun barrel when straightening can be done with the help of a dragonfly arranged on the housing.

Zur Durchführung eines Verkantungsausgleiches kann aber auch vorgesehen werden, dass die beiden rohrförmigen Teile des Messsystems in einer Ebene senkrecht zur Rohrerhöhungsebene oder einer parallel zu dieser senkrechten Ebene befindlichen Ebene voneinander beabstandet angeordnet sind. Eine zweite Schlauchwaage ist eingebunden.In order to perform a tilt compensation, it can also be provided that the two tubular parts of the measuring system are arranged at a distance from each other in a plane perpendicular to the tube elevation plane or a plane parallel to this plane. A second tube scale is integrated.

In diesem Fall, da die Verkantung mit zwei parallel zueinander wirkenden Schlauchwaagesystemen angezeigt werden soll, sind diese miteinander verbunden. Eine vorhandene Verkantung wird hierbei durch ein unterschiedliches Flüssigkeitsniveau der beiden vorderen Anzeigerohre angezeigt. Je weiter die beiden vorderen Röhren auseinander liegen, desto genauer kann die Verkantung abgelesen werden. Die hintere Röhre kann dabei in einer zusammengefasst oder doppelt ausgeführt sein.In this case, since the tilting is to be displayed with two parallel-acting tube weighing systems, they are interconnected. An existing canting is indicated by a different liquid level of the two front indicator tubes. The further the two front tubes are apart, the more accurate the cant can be read. The rear tube can be combined or doubled.

Sofern sowohl ein Höhenrichten (Neigen) als auch ein Verkantungsausgleich der entsprechenden Waffe erfolgen soll, können zwei von einander beabstandete, aber beispielsweise parallel zueinander angeordnete Messsysteme vorgesehen sein, die beide in einer parallel zu der Rohrerhöhungsebene befindlichen Ebene angeordnet und miteinander verbunden sind.If both a Höhenrichten (tilt) and a tilt compensation of the corresponding Weapon, two spaced apart, but for example parallel to each other arranged measuring systems can be provided, both of which are arranged in a plane parallel to the pipe riser level and connected to each other.

Die beiden, beispielsweise aus Kunststoff bestehenden Röhrchen 6 sind über in das Gehäuse 3 ober- und unterseitig eingelassene Rohrverbindungen miteinander verbunden, sodass zwischen den beiden, teilweise mit einer Flüssigkeit (beispielsweise Wasser) 7 gefüllten Röhrchen 6 ein Flüssigkeitsaustausch stattfindet.The two, for example made of plastic tube 6 are connected to each other in the housing 3 above and below the tube connections, so that between the two, partially filled with a liquid (for example water) 7 6 tubes liquid exchange takes place.

Das dem Betrachter zugewandte erste Röhrchen 6 weist einen durchsichtigen Bereich 8 zur Beobachtung der Lage des Flüssigkeitsspiegels 9 auf. An diesem durchsichtigen Bereich 8 des ersten Röhrchens 6 ist eine sich parallel zu dem ersten Röhrchen 6 erstreckende Messskala 10 an dem Gehäuse 3 angeordnet. Bei einem breiteren durchsichtigen Bereich kann die Skala 10 auch auf diesem integriert sein.The viewer facing the first tube 6 has a transparent area 8 for monitoring the position of the liquid level 9. At this transparent region 8 of the first tube 6, a measuring scale 10 extending parallel to the first tube 6 is arranged on the housing 3. With a wider transparent area, the scale 10 can also be integrated on this.

Beim Höhenrichten der Waffe ändert sich mit der Elevation des Waffenrohres 1 der Flüssigkeitsstand innerhalb der beiden kommunizierenden Röhrchen 6, sodass an der dem ersten Röhrchen 6 zugeordneten Messskala 10 die Elevation abgelesen werden kann.When leveling the weapon changes with the elevation of the gun barrel 1, the liquid level within the two communicating tubes 6, so that at the first tube 6 associated measuring scale 10, the elevation can be read.

Das erste Röhrchen 6 kann den gleichen Durchmesser wie das zweite Röhrchen aufweisen. Es kann vorzugsweise aber auch vorgesehen sein, dass das erste Röhrchen 6 einen geringeren Durchmesser als das zweite Röhrchen besitzt, sodass sich die Anzeigengenauigkeit des Meßsystems gegenüber einer Anordnung von Röhrchen mit gleichem Durchmesser wesentlich vergrößert (d.h. gegebenenfalls fast verdoppelt).The first tube 6 may have the same diameter as the second tube. However, it can preferably also be provided that the first tube 6 has a smaller diameter than the second tube, so that the display accuracy of the measuring system relative to an array of tubes of the same diameter significantly increased (ie, if necessary, almost doubled).

Diese Erhöhung der Anzeigengenauigkeit aufgrund unterschiedlicher Durchmesser der beiden Röhrchen eines kommunizierenden Systems lässt sich anhand der schematisch dargestellten Figuren 2-5 verdeutlichen. Dabei zeigen die Fig.2 und 3 das Messsystem 4, bei dem das erste Röhrchen 6 den gleichen Durchmesser aufweist, wie das mit 6' bezeichnete zweite Röhrchen. Hingegen geben die Fig.4 und 5 ein zweites Messsystem 4' wieder, bei dem der Durchmesser des zweiten Röhrchens 6" wesentlich größer gewählt ist als der Durchmesser des ersten Röhrchens 6.This increase in display accuracy due to different diameters of the two tubes of a communicating system can be seen from the schematically illustrated Figures 2-5 clarify. The show Fig.2 and 3 the measuring system 4, in which the first tube 6 has the same diameter as the second tube designated 6 '. On the other hand give the 4 and 5 a second measuring system 4 'again, in which the diameter of the second tube 6 "chosen to be substantially larger than the diameter of the first tube. 6

Während die Fig.2 und 4 die jeweilige Anordnung der Messsysteme 4 und 4' bei senkrechter Rohrstellung des Waffenrohres 1 zeigen, geben die Fig.3 und 5 die Anordnungen der beiden Meßsysteme 4, 4' bei einem Elevationswinkel von ca. 60° wieder. Wie den Fig.3 und 5 zu entnehmen ist, sind der Anzeigenbereich 11 und damit auch die Anzeigengenauigkeit im Falle der Fig.5 deutlich größer als im Falle der Fig.3.While the FIGS. 2 and 4 show the particular arrangement of the measuring systems 4 and 4 'in the vertical position of the pipe gun pipe 1, give the 3 and 5 the arrangements of the two measuring systems 4, 4 'at an elevation angle of about 60 ° again. Like that 3 and 5 can be seen, the display area 11 and thus the display accuracy in the case of Figure 5 significantly larger than in the case of Figure 3 ,

Wie Fig.1 zu entnehmen ist, befindet sich an dem Gehäuse 3 außenseitig eine Libelle 12, um eine beim Höhenrichten eventuell auftretende Verkantung des Waffenrohres 1 auszugleichen.As Fig.1 can be seen, is located on the outside of the housing 3 a dragonfly 12 to compensate for any vertical alignment occurring canting of the gun barrel 1.

Zur Neigungsermittlung sollte zusätzlich auch eine Verkantung ermittelbar sein. In einer einfachsten Ausführung kann eine Messskala 10 herangezogen werden, die beidseitig des durchsichtigen Bereiches 8 angebracht ist. Liegt eine Verkantung vor, besteht eine sichtliche Schieflage des Flüssigkeitsniveaus zwischen den beiden Teilstrichen der Skala 10. Selbiges kann ermittelt werden, wenn der durchsichtige Bereich 8 die Skala 10 trägt und die Teilstriche nicht nur quer sondern auch lang ausgeführt sind.In addition, tilting should also be ascertainable for inclination determination. In a simplest embodiment, a measuring scale 10 can be used, which is mounted on both sides of the transparent area 8. There is a tilting, there is a visible imbalance of the liquid level between the two divisions of the scale 10. The same can be determined if the transparent area 8, the scale 10 carries and the graduations are not only transversely but also made long.

Weiter schematisch dargestellte Varianten zeigen die Fig. 6a, b sowie 7a, 7a und 8a, 8b.Further schematically illustrated variants show the Fig. 6a, b such as 7a, 7a and 8a, 8b ,

Da erfindungsgemäss die Verkantung mit zwei parallel zueinander wirkenden Schlauchwaagesystemen angezeigt werden soll, müssen diese miteinander verbunden sein. Eine vorhandene Verkantung wird hierbei durch ein unterschiedliches Flüssigkeitsniveau der beiden vorderen Anzeigeröhrchen angezeigt (Fig. 6a -ohne Verkantung, Fig. 6b - mit Verkantung). Je weiter die beiden vorderen Röhrchen auseinander liegen, desto genauer kann die Verkantung abgelesen werden. Die hintere Röhre kann dabei in einer zusammengefasst oder doppelt aufgeführt sein.Since, according to the invention, the tilting is to be displayed with two hose weighing systems acting in parallel with one another, they must be connected to one another. An existing tilt is indicated by a different fluid level of the two front indicator tubes ( Fig. 6a without tilting, Fig. 6b - with tilting). The farther the two front tubes are apart, the more accurate the cant can be read. The rear tube can be summarized in one or be listed twice.

Die Verkantung kann beispielhaft auch durch ein zweites Messsystem nach dem Schlauchwaageprinzip angezeigt werden, welches senkrecht zum ersten anzuordnen ist. Bei der Anwendung ist eine der Schlauchwaagen auszurichten (Verkantung) und die andere zeigt die Neigung an (Fig. 7a, Fig. 7b). Insgesamt sind dann drei Anzeigeröhrchen zu beachten- zwei für die Verkantung und eine für die Neigung.The canting can be displayed by way of example also by a second measuring system according to the tube scale principle, which is to be arranged perpendicular to the first. In the application, one of the tube scales should be aligned (tilt) and the other should indicate the inclination ( Fig. 7a, Fig. 7b ). All in all, three indicator tubes must be observed - two for tilting and one for tilting.

Werden die zwei unabhängigen Schlauchwaagesysteme in einem Winkel zueinander angeordnet, erfolgt das Ablesen an den beiden vorderen Röhren (Fig. 8a, Fig. 8b). Für den Ausgleich der Verkantung müssen beide Röhren die gleiche Flüssigkeitshöhe haben. Die gemeinsame Höhe zeigt dann die Neigung an.If the two independent tube weighing systems are arranged at an angle to each other, the reading on the two front tubes ( Fig. 8a, Fig. 8b ). To balance the tilt, both tubes must have the same fluid height. The common height then indicates the slope.

Fig.9 zeigt ein erfindungsgemässes Ausführungsbeispiel unter Verwendung der Vorrichtung 2' näher. Diese besitzt zwei der Messsysteme 4, die voneinander beabstandet in einer parallel zu der Rohrerhöhungsebene befindlichen Ebene angeordnet sind. Auch bei diesem Ausführungsbeispiel umfasst die erfindungsgemäße Vorrichtung 2' ein rohrförmiges Gehäuse 3', welches hier beispielsweise an der Mündung eines Waffenrohres 1 befestigt ist. Die jeweils ersten Röhrchen 6 der beiden Messsysteme 4 sind bei diesem Ausführungsbeispiel nach außen gewölbt ausgebildet, um in entsprechenden Bereichen eine weitere Erhöhung der Anzeigengenauigkeit zu erreichen. Die über nicht dargestellte Verbindungsleitungen mit den ersten Röhrchen 6 verbundenen zweiten Röhrchen 6' des jeweiligen Messsystems sind wiederum auf der Rückseite des Gehäuses 3' angeordnet. Wie in der Fig. erkennbar, nimmt die Flüssigkeit 7 in den beiden Anzeigen unterschiedliche Niveaus an. Die damit ermittelten Werte dienen dann vorzugsweise dem Verkantungsausgleich. Figure 9 shows an inventive embodiment using the device 2 'in more detail. This has two of the measuring systems 4, which are arranged at a distance from each other in a plane parallel to the tube elevation plane. Also in this embodiment, the device 2 'of the invention comprises a tubular housing 3', which is attached here, for example, at the mouth of a gun barrel 1. The respective first tubes 6 of the two measuring systems 4 are curved in this embodiment outwardly curved in order to achieve a further increase in the display accuracy in corresponding areas. The not shown via connecting lines with the first tube 6 connected second tube 6 'of the respective measuring system are in turn arranged on the back of the housing 3'. As can be seen in the figure, the liquid 7 assumes different levels in the two displays. The values thus determined are then preferably used for tilt compensation.

Weitere nicht näher beschriebene Darstellungen möglicher Messanordnungen der beiden Schlauchwaagen sind in der Fig. 10 a und der Fig. 10b erkennbar.Other unspecified representations of possible measurement arrangements of the two tube scales are in the Fig. 10 a and the Fig. 10b recognizable.

Fig. 11 zeigt eine weitere beispielhafte Variante auf, mit der die Anzeige der Verkantung mit und ohne Neigung durch zwei unabhängige Schlauchwaagesysteme möglich ist, wobei die beiden Schlauchwaagen in einem Winkel zueinander angeordnet sind. Auch deutet der dicke Pfeil die Schussrichtung an. Fig. 11 shows a further exemplary variant with which the display of tilting with and without inclination is possible by two independent Schlauchwaagesysteme, wherein the two hose scales are arranged at an angle to each other. Also indicates the thick arrow to the firing direction.

Es versteht sich, dass noch viele weitere beispielhafte Varianten möglich sind, die eine Messung der Neigung / Verkantung nach dem Schlauchwaageprinzip ermöglichen. Zudem ist die Anwendung nicht auf Waffen mit überhöhter Verschussbahn beschränkt. Inwieweit eine Nutzung bei einer kleineren handlicheren Ausführung bei Kleinkaliberwaffen oder Mittelkaliberwaffen jedoch sinnvoll ist, kann derzeit noch nicht eingeschätzt werden. Ausgeschlossen ist diese Nutzung jedoch nicht.It is understood that many more exemplary variants are possible, which is a measurement of Allow tilting / tilting according to the hose scale principle. In addition, the application is not limited to weapons with excessive Verschußbahn. To what extent it makes sense to use it with a smaller, more manageable version with small caliber weapons or medium-caliber weapons, can not yet be estimated. However, this use is not excluded.
