Abstract
Description
Die Erfindung betrifft ein Tastpotentiometer, insbesondere für eine Schnelleinweisungsvorrichtung an einem Beobachtungs- und/oder Geschützfahrzeug, wobei das Tastpotentiometer im Innern des Fahrzeuges um einen Beobachterplatz herum angeordnet ist und eine schlauchartige Isolierhülle aufweist, in welcher eine Widerstandsbahn und eine Kontaktbahn koaxial zueinander verlaufend in einem bestimmten Abstand voneinander angeordnet sind.The invention relates to a touch potentiometer, in particular for a rapid instruction device on an observation and / or gun vehicle, the touch potentiometer is arranged inside the vehicle around an observer position and has a tubular insulating sleeve in which a resistance track and a contact track arranged coaxially to each other at a certain distance from each other are.
Bei Fahrzeugen der eingangs genannten Art, wie z.B. Kampfpanzern, wird das Gelände aus dem Innern des Fahrzeugs ständig visuell beobachtet, entweder direkt aus der offenen Luke oder über fest eingebaute Winkelspiegel. Wird ein mögliches Ziel entdeckt, so muss dieses zur genauen Beurteilung durch ein drehbar montiertes Periskop erfasst werden, dessen Gesichtsfeld stark eingeschränkt ist. Hierfür ist es notwendig, das Periskop (und gegebenenfalls das Geschützrohr) möglichst rasch in die Richtung des Zieles einzuweisen, d.h. der Beobachter muss die Richtung, welche er visuell erfasst hat, auf das Periskop übertragen, damit er bei anschliessender Sicht durch dieses sich rasch im Gelände zurecht findet. Allgemein üblich ist das Einweisen durch Betätigen eines Richtgriffs oder Steuerknüppels zum servogetriebenen Drehen des Periskops oder Turms, wobei die Richtung im Innern des Fahrzeugs an einer Skala angezeigt wird. Der Beobachter muss also in der Regel seine Körperhaltung ändern und die Richtung auf die Skala umsetzen, wodurch das Wiederauffinden der Richtung erschwert wird und wertvolle Zeit verloren geht.For vehicles of the type mentioned above, such as Main battle tanks, the terrain is out constantly visually observed inside the vehicle, either directly from the open hatch or via permanently installed angle mirrors. If a potential target is discovered, it must for precise assessment by a rotatably mounted periscope, its field of view is severely restricted. For this it is necessary to use the periscope (and if necessary the gun barrel) as quickly as possible in the direction of the target, i.e. the The observer must transfer the direction that he has visually captured to the periscope, so that he can quickly find his way through the terrain when the view is clear. Generally It is common to instruct by operating a directional handle or joystick servo-driven turning of the periscope or tower, with the direction inside the Vehicle is displayed on a scale. As a rule, the observer must have his Change posture and change direction on the scale, making it easy to find the direction becomes difficult and valuable time is lost.
Mit der EP-A-0 455 838 ist eine Schnelleinweisungsvorrichtung bekannt geworden, die vorstehend enNähnte Nachteile nicht aufweist. Hierbei ist entlang einem Lukenrand ringförmig um den Beobachterplatz herum ein Tastpotentiometer angeordnet, das als analoger Winkelgeber für den Schnellantrieb eines Periskopes dient. Das Tastpotentiometer weist eine biegsame, schlauchartige Isolierhülle auf, die aus einem Halbrund-Hohlprofil gebildet ist. An der halbkreisförmigen Innenseite der Isolierhülle ist eine Widerstandsbahn angeordnet, die aus einem in einem Schlauch aus elektrisch leitfähigem Elastomer längsbeweglich geführten Widerstandsdraht besteht. Parallel zur Widerstandsbahn und in einem bestimmten Abstand zu dieser ist an der ebenen Innenseite der Isolierhülle eine Kontaktbahn angeordnet, die aus einem Flachprofil aus Metall gebildet ist. Auf die Enden des Schlauches, in welchem der Widerstandsdraht geführt wird, sind Rohrstücke aufgesetzt. Die Enden des Widerstandsdrahtes sind über flexible Litzenleiter mit einem Kabel verbunden, wobei die flexiblen Litzenleiter in den Rohrstücken wendelartig verlaufend geführt werden. Mit dieser Massnahme soll ein Längenausgleich ermöglicht werden, da beim Biegen des Tastpotentiometers der Widerstandsdraht in Richtung der Rohrstücke aus dem Schlauch herausgeschoben wird. Das Tastpotentiometer ist mit seiner ebenen Auflagefläche am Lukenrand befestigt, während der halbkreisförmige Teil der Isolierhülle mit der im Innern befestigten Widestandsbahn dem Beobachterplatz zugewandt ist. Wenn ein Beobachter in einer anvisierten Richtung das Tastpotentiometer betätigt, indem er die schlauchartige Isolierhülle an der betreffenden Stelle zusammendrückt bis die Widerstandsbahn die Kontaktbahn berührt, so wird ein elektrisches Potential abgegriffen, das ein Mass für die Richtung darstellt, in welche das Periskop geschwenkt werden muss. EP-A-0 455 838 discloses a rapid instruction device which does not have the disadvantages mentioned above. In this case, a tactile potentiometer is arranged along a hatch edge in a ring around the observer area, which serves as an analog angle sensor for the rapid drive of a periscope. The touch potentiometer has a flexible, hose-like insulating sleeve which is formed from a semicircular hollow profile. Arranged on the semicircular inside of the insulating sleeve is a resistance track, which consists of a resistance wire which is guided to move longitudinally in a tube made of electrically conductive elastomer. Parallel to the resistance track and at a certain distance from it, a contact track is arranged on the flat inside of the insulating sleeve, which is formed from a flat profile made of metal. Pipe pieces are placed on the ends of the hose in which the resistance wire is guided. The ends of the resistance wire are connected to a cable by means of flexible stranded conductors, the flexible stranded conductors being guided in a helical manner in the tube pieces. With this measure, a length compensation is to be made possible, since when the pushbutton potentiometer is bent, the resistance wire is pushed out of the hose in the direction of the pipe sections. The tactile potentiometer is attached to the hatch edge with its flat contact surface, while the semicircular part of the insulating sleeve with the resistance membrane attached to the inside faces the observer's place. If an observer actuates the touch potentiometer in a targeted direction by squeezing the tube-like insulating sleeve at the relevant point until the resistance track touches the contact track, an electrical potential is tapped, which is a measure of the direction in which the periscope must be swiveled .
Das Tastpotentiometer der vorstehend beschriebenen Schnelleinweisungsvorrichtung hat den Nachteil, dass beim Biegen zwecks Anpassung an den Lukenrand die schlauchartige Isolierhülle einknicken kann und ein unerwünschter Kontakt zwischen Widerstands-und Kontaktbahn hergestellt wird. Ausserdem sind durch das als Kontaktbahn verwendete Flachprofil aus Metall beim Einbau des Tastpotentiometers keine kleineren Radien möglich, so dass je nach Gestaltung des Lukenrandes Schwierigkeiten auftreten können. Weiterhin ist es nachteilig, dass die Widerstandsbahn bei jeder Betätigung mechanisch beansprucht wird, so dass unter Umständen Widerstandsänderungen auftreten können und ein erneuter Abgleich notwendig ist. Ein weiterer Nachteil liegt in der relativ aufwendigen und teuren Verbindung des Widerstandsdrahtes mit dem Kabel.The tactile potentiometer of the above-described quick instruction device has the disadvantage that when bending to adapt to the hatch edge, the tube-like Insulation can buckle and an undesirable contact between the resistance and contact track will be produced. In addition, the flat profile used as a contact track made of metal no smaller radii are possible when installing the touch potentiometer, so that depending on the design of the hatch edge, difficulties may arise. Furthermore it is disadvantageous that the resistance track is mechanically stressed with each actuation, so that changes in resistance may occur and a new adjustment necessary is. Another disadvantage is the relatively complex and expensive connection the resistance wire with the cable.
Der Erfindung liegt die Aufgabe zugrunde ein Tastpotentiometer der eingangs genannten Art vorzuschlagen, das vorstehend erwähnte Nachteile nicht aufweist.The invention has for its object a touch potentiometer of the type mentioned propose that does not have the disadvantages mentioned above.
Diese Aufgabe wird durch die im Patentanspruch 1 angegebene Erfindung gelöst. Hierbei besteht die schlauchartige Isolierhülle aus zwei Profilen, wobei in mindestens einem der Profile eine Versteifungseinrichtung vorgesehen ist. In einer bevorzugten Ausführungsform besteht die Versteifungseinrichtung aus in einem der Profile integrierten röhrenförmigen Kanälen, wobei die Versteifungseinrichtung in dem einen, eine Betätigungsfläche des Tastpotentiometers aufweisenden Profil integriert ist.This object is achieved by the invention specified in claim 1. Here the tubular insulating sleeve consists of two profiles, with at least one of the Profiles a stiffening device is provided. In a preferred embodiment the stiffening device consists of tubular integrated in one of the profiles Channels, the stiffening device in one, an actuating surface of the touch potentiometer having profile is integrated.
Die mit der Erfindung erzielten Vorteile sind insbesondere darin zu sehen, dass durch die vorgeschlagene Versteifungseinrichtung kleinere Biegeradien bei der Montage erreichbar sind und trotzdem ein Einknicken der schlauchartigen Isolierhülle und die dadurch hervorgerufene fehlerhafte Kontaktgabe vermieden werden. Durch die Verwendung einer hochflexiblen Flachlitze als Kontaktbahn wird bei der Montage des Tastpotentiometers die Herstellung kleinerer Biegeradien unterstützt und die Betätigung des Tastpotentiometers erleichtert. Weitere Vorteile ergeben sich daraus, dass die Widerstandsbahn bei der Betätigung des Tastpotentiometers nicht mehr bewegt wird. Dadurch kann die Verbindung zwischen dem Widerstandsdraht und dem Kabel einfacher und billiger gestaltet werden. Ausserdem tritt keine durch mechanische Beanspruchung des Widerstandsdrahtes hervorgerufene Aenderung des elektrischen Widerstandes mehr auf, so dass nachträglich nicht mehr abgeglichen werden muss.The advantages achieved with the invention can be seen in particular in that proposed stiffening device smaller bending radii attainable during assembly are and still a buckling of the hose-like insulating sleeve and the resulting incorrect contact can be avoided. By using a highly flexible Flat wire as a contact track is used in the assembly of the touch potentiometer supports smaller bending radii and makes it easier to operate the touch potentiometer. Further advantages result from the fact that the resistance track when actuated of the touch potentiometer is no longer moved. This allows the connection between the resistance wire and the cable can be made easier and cheaper. In addition, there is no mechanical stress on the resistance wire Change in electrical resistance more, so that subsequently not needs to be adjusted more.

Profilen 3, 4 zusammengesetzt und weist einen im wesentlichen rechteckigen Querschnitt
auf. An der Isolierhülle 2 ist eine Versteifungseinrichtung vorgesehen, die aus zwei
röhrenförmigen Kanälen 5, 6 besteht, die in dem einen, eine Betätigungsfläche 7 des Tastpotentiometers

Schmalseiten einer rechteckigen Vertiefung 8 angeordnet, die symmetrisch zu einer Mittelachse
9 liegend an der Innenseite des Profils 3 vorgesehen ist. In der rechteckigen Vertiefung

des Tastpotentiometers 1 durch das andere Profil 4 verschlossen. Zu diesem
Zweck wird das Profil 4 schwalbenschwanzartig im Profil 3 geführt, wobei trapezförmige
Führungsleisten 11 des Profils 4 in trapezförmige Führungsnuten 12 des Profils 3 eingreifen.
An der Innenseite des Profils 4 ist eine symmetrisch zur Mittelachse 9 liegende Nut 13
vorgesehen, in der eine Widerstandsbahn 14 angeordnet ist. Die Widerstandsbahn 14
besteht aus einem Widerstandsdraht 15, auf dem Kontaktperlen 16, gegenseitig getrennt

15 ist, aus elektrisch leitendem Material, beispielsweise aus Elastomerstoffen,
aufgereiht sind. Die dem Innern des Profils 3 zugewandten Wände 17, 18 der Kanäle 5,

Stopfen 19 ein Anschlusskabel 20 geführt ist. Das Anschlusskabel 20 weist drei Leiter auf,
wovon der eine Leiter direkt mit dem einen Ende des Widerstandsdrahtes 15 und der andere
Leiter über eine Rückleitung 21 mit dem anderen Ende des Widerstandsdrahtes 15
verbunden ist. Der weitere Leiter des Anschlusskabels 20 ist mit der Kontaktbahn 10 verbunden.
Die Rückleitung 21 ist in einer von zwei kanalförmigen geschlitzen Röhren 22, 23
verlegt, die im Profil 4 zu beiden Seiten der Nut 13 vorgesehen und über Schlitze 24 mit der

des Tastpotentiometers 1 entlang des Randes 29 der Fahrzeugluke 30 können dank
der vorgeschlagenen, aus den zwei Kanälen 5, 6 bestehenden Versteifungseinrichtung Biegeradien
bis zu 12 cm erzielt werden, ohne dass die Isolierhülle 2 einknicken kann und ein
unerwünschter Kontakt zwischen der Kontaktbahn 10 und der Widerstandsbahn 14 hergestellt
wird. Die problemlose Herstellung von derart kleinen Biegeradien ist insbesondere bei
