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 tactile potentiometer, in particular for a rapid instruction device on an observation and / or gun vehicle, the tactile potentiometer being arranged in the interior of the vehicle around an observer position and having a tubular insulating sleeve in which a resistance track and a contact track run coaxially with one another certain distance from each other.

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.In vehicles of the type mentioned at the beginning, such as battle tanks, the terrain is constantly visually observed from inside the vehicle, either directly from the open hatch or via permanently installed angle mirrors. If a possible target is discovered, it must be recorded for precise assessment by means of a rotatably mounted periscope, whose field of vision is severely restricted. For this it is necessary to instruct the periscope (and possibly the gun barrel) as quickly as possible in the direction of the target, ie the observer must transfer the direction that he has visually detected to the periscope, so that he can quickly find his way through the terrain when the view is clear. It is generally customary to instruct by actuating a directional handle or control stick for servo-driven rotation of the periscope or tower, the direction inside the vehicle being indicated on a scale. As a rule, the observer has to change his posture and change the direction on the scale, which makes finding the direction more difficult and valuable time is lost.

Mit der EP-A-0 455 838 ist eine Schnelleinweisungsvorrichtung bekannt geworden, die vorstehend erwähnte 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 in a longitudinally movable manner 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 position. 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 represents 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 pushbutton potentiometer of the above-described rapid instruction device has the disadvantage that when bending for the purpose of adaptation to the hatch edge, the tube-like insulating sleeve can buckle and an undesired contact between the resistance and contact path is produced. In addition, the flat profile used as a contact track made of metal, no smaller radii are possible when installing the tactile potentiometer, so that difficulties can arise depending on the design of the hatch edge. Furthermore, it is disadvantageous that the resistance track is mechanically stressed each time it is actuated, so that under certain circumstances changes in resistance can occur and a new adjustment is necessary. Another disadvantage is the relatively complex and expensive connection of the resistance wire to 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 to propose a touch potentiometer of the type mentioned, which 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 tube-like insulating sleeve consists of two profiles, a stiffening device being provided in at least one of the profiles. In a preferred embodiment, the stiffening device consists of tubular channels integrated in one of the profiles, the stiffening device being integrated in the one profile, which has an actuating surface of the touch potentiometer.

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 are to be seen in particular in the fact that the proposed stiffening device enables smaller bending radii to be achieved during assembly, and nevertheless prevents the hose-like insulating sleeve from buckling and the resulting incorrect contacting. By using a highly flexible flat wire as a contact track, the manufacture of smaller bending radii is supported during assembly of the touch potentiometer and the actuation of the touch potentiometer is made easier. Further advantages result from the fact that the resistance path is no longer moved when the push-button potentiometer is actuated. This makes the connection between the resistance wire and the cable easier and cheaper. In addition, there is no longer any change in the electrical resistance caused by mechanical stress on the resistance wire, so that it is no longer necessary to adjust subsequently.

In den Fig.1 bis 4 ist mit 1 ein Tastpotentiometer bezeichnet, das eine schlauchartige Isolierhülle 2 aufweist. Die Isolierhülle 2 ist aus zwei, beispielsweise aus Silikongummi hergestellten 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 1 aufweisenden Profil 3 integriert sind. Die Kanäle 5, 6 sind zu beiden 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 8 ist eine Kontaktbahn 10 befestigt, die aus einer hochflexiblen Flachlitze gebildet ist. Eine parallel zur Betätigungsfläche 7 verlaufende offene Seite des Profils 3 wird bei der Endmontage 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 durch Isolierringe 16a, deren Innenbohrung grösser als der Aussendurchmesser des Widerstandsdrahtes 15 ist, aus elektrisch leitendem Material, beispielsweise aus Elastomerstoffen, aufgereiht sind. Die dem Innern des Profils 3 zugewandten Wände 17, 18 der Kanäle 5, 6 sind kreisbogenförmig gekrümmt, wobei der Krümmungsmittelpunkt auf der Mittelachse 9 liegt und mit dem Mittelpunkt des Widerstandsdrahtes 15 zusammenfällt. 1 to 4 , 1 denotes a touch potentiometer, which has a tubular insulating sleeve 2 . The insulating sleeve 2 is composed of two profiles 3, 4 , for example made of silicone rubber, and has an essentially rectangular cross section. A stiffening device is provided on the insulating sleeve 2 , which consists of two tubular channels 5, 6 , which are integrated in the one profile 3 , which has an actuating surface 7 of the touch potentiometer 1 . The channels 5, 6 are arranged on both narrow sides of a rectangular recess 8 , which is provided symmetrically to a central axis 9 on the inside of the profile 3 . In the rectangular recess 8 , a contact track 10 is attached, which is formed from a highly flexible flat wire. A running parallel to the operating surface 7 open side of the profile 3 is sealed by the other profile 4 in the final assembly of the Tastpotentiometers. 1 For this purpose, the profile 4 is guided in the profile 3 like a dovetail, with trapezoidal guide strips 11 of the profile 4 engaging in trapezoidal guide grooves 12 of the profile 3 . On the inside of the profile 4 there is a groove 13 which is symmetrical to the central axis 9 and in which a resistance track 14 is arranged. The resistance track 14 consists of a resistance wire 15 , on which contact beads 16 , separated from one another by insulating rings 16a , the inner bore of which is larger than the outer diameter of the resistance wire 15 , are made of electrically conductive material, for example made of elastomeric materials. The walls 17, 18 of the channels 5, 6 facing the inside of the profile 3 are curved in the shape of a circular arc, the center of curvature being on the central axis 9 and coinciding with the center of the resistance wire 15 .

Vorteilhafterweise ist dabei der Aussendurchmesser der Isolierringe 16a etwas kleiner als der der anstossenden Kontaktperlen 16.Advantageously, the outer diameter of the insulating rings 16a is somewhat smaller than that of the abutting contact beads 16 .

Die Enden der Isolierhülle 2 sind mit einem Stopfen 19 verschlossen, wobei durch den einen 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 Innenseite des Profils 4 verbunden sind.The ends of the insulating cover 2 are sealed with a plug 19, wherein a connecting cable 20 is guided through a plug 19th The connecting cable 20 has three conductors, one of which is connected directly to one end of the resistance wire 15 and the other conductor is connected to the other end of the resistance wire 15 via a return line 21 . The further conductor of the connecting cable 20 is connected to the contact track 10 . The return line 21 is laid in one of two channel-shaped slotted tubes 22, 23 , which are provided in the profile 4 on both sides of the groove 13 and are connected to the inside of the profile 4 via slots 24 .

Gemäss Fig.5 ist das Tastpotentiometer 1 an einer aus einem C-Profil bestehen-den Schiene 25 befestigt, die in seitlich am Profil 3 des Tastpotentiometers 1 befindliche Nuten 26 eingreift. Die Schiene 25 wird wie nicht weiter dargestellt an einem Winkelträger 27 gehalten, der mittels Schrauben 28 am Rand 29 einer Fahrzeugluke 30 befestigt ist. Beim Montieren 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 nicht kreisförmigen, über einen Flach 31 mit dem Luckenrand verbundenen Fahrzeugluken 30 von Vorteil. 5 , the touch potentiometer 1 is fastened to a rail 25 consisting of a C profile, which engages in grooves 26 located on the side of the profile 3 of the touch potentiometer 1 . As not shown, the rail 25 is held on an angle bracket 27 which is fastened to the edge 29 of a vehicle hatch 30 by means of screws 28 . When mounting the touch potentiometer 1 along the edge 29 of the vehicle hatch 30 , thanks to the proposed stiffening device consisting of the two channels 5, 6 , bending radii of up to 12 cm can be achieved without the insulating sleeve 2 being able to buckle and undesired contact between the contact path 10 and the resistance track 14 is produced. The problem-free production of such small bending radii is particularly advantageous in the case of non-circular vehicle hatches 30 connected to the gap edge by a flat 31 .

Das vorstehend beschriebene Tastpotentiometer 1 ist beispielsweise an einer Servosteuerung für den Drehantrieb eines Periskopes angeschlossen. Wenn ein in der Fahrzeugluke 30 befindlicher Beobachter in einer anvisierten Richtung die Betätigungsfläche 7 des Tastpotentiometers 1 an der betreffenden Stelle niederdrückt bis die Kontaktbahn 10 die Widerstandsbahn 14 berührt, so wird ein elektrisches Potential abgegriffen, das ein Mass für die Richtung darstellt, in welche das Periskop geschwenkt werden muss.The tactile potentiometer 1 described above is connected, for example, to a servo control for the rotary drive of a periscope. When an in-vehicle hatch 30 observers in a targeted direction, the actuating surface 7 of the Tastpotentiometers 1 at that point depresses until the contact path 10, the resistor track 14 contacts, an electrical potential is tapped, which is a measure of the direction in which the Periscope must be swiveled.
