Description

Die Erfindung richtet sich auf eine Vorrichtung zur Ermittlung der Zuschauerreaktion auf einen oder mehrere auf einem Videoband abgespeicherte, über eine Wiedergabevorrichtung abgespielte Video- und Tonsequenzen, insbesondere Werbespot, umfassend wenigstens einen Bildschirm zur Wiedergabe des Videospots und eine Einrichtung zur Erzeugung eines Beurteilungssignals durch den Zuschauer während der Beobachtung der Videosequenzen sowie wenigstens eine Einrichtung zur Abspeicherung des derart erzeugten Beurteilungssignals in zeitlicher Koordination mit den abgespielten Videosequenzen und eine steuernde Datenverarbeitungs- und Speichereinrichtung.The invention relates to a device for determining the viewer's reaction to one or more video and sound sequences, in particular commercials, stored on a video tape and played back via a playback device, comprising at least one screen for playing back the video spot and a device for generating a judgment signal by the viewer during the observation of the video sequences and at least one device for storing the evaluation signal generated in this way in time coordination with the played video sequences and a controlling data processing and storage device.

Derartige Vorrichtungen sind an sich bekannt und haben sich als marketingtechnisches Testinstrument sehr gut bewährt, insbesondere um Werbespots vor ihrer Ausstrahlung auf ihre psychologische Akzeptanz hin zu testen.Such devices are known per se and have proven to be a very good marketing test instrument proven, especially to test commercials for their psychological acceptance before they are broadcast.

Bei vorbekannten Systemen dieser Art ist für eine Mehrzahl gleichzeitig anwesender Zuschauer ein einziger Videorekorder zum Abspielen der zu beurteilenden Videospots und ein einziger PC zur Verarbeitung und Steuerung des Testablaufs vorgesehen. Die Videosequenzen werden über einen oder mehrere Bildschirme durch die Testpersonen gleichzeitig beobachtet. Darüber hinaus verfügt jede Testperson über einen Schieberegler oder Tastenblock, der vor der Testperson angeordnet ist, und mit dessen Hilfe ein spontanes Beurteilungssignal entsprechend einer Gemütsäußerung der Testperson erzeugt werden kann.In previously known systems of this type, a single video recorder for playing the video spots to be assessed and a single PC for processing and controlling the test sequence are provided for a plurality of viewers present at the same time. The video sequences are observed simultaneously on one or more screens by the test subjects. In addition, each test person has a slider or keypad, which is arranged in front of the test person and with the help of which a spontaneous assessment signal can be generated in accordance with a testimony of the test person.

Diese vorbekannten Systeme weisen sowohl technisch als auch unter Marktforschungsaspekten wesentliche Nachteile auf. Die nur eine zur Verfügung stehende Bildquelle bedingt nämlich zunächst, daß ein synchroner Testbeginn für alle Testpersonen zwingend erforderlich ist, ebenso wie der weitere Testverlauf für alle Zuschauer synchron erfolgen muß. Dies bedingt natürlich eine zeitliche Koordination der Zuschauer, welche die Testabwicklung erschwert.These previously known systems have significant disadvantages both technically and from a market research perspective. The fact that only one image source is available initially means that a synchronous test start is imperative for all test persons, just as the further test process must be carried out synchronously for all viewers. Of course, this requires a time coordination of the viewers, which complicates the test execution.

Weiterhin ist zu berücksichtigen, daß bei derartigen Systemen in einzelnen Testphasen, in welchen der Fortgang des Tests von der Reaktion der Testpersonen abhängt, jeweils die langsamste Testperson aus der Gruppe die Geschwindigkeit des Vorgehens bestimmt, so daß die schnelleren Testpersonen konditioniert werden und durch Eigenreflektionen, für welche diese Testpersonen Zeit gewinnen, der Test beeinflußt werden.It should also be taken into account that in such systems in individual test phases, in which the progress of the test depends on the reaction of the test subjects, the slowest test subject from the group determines the speed of the procedure, so that the faster test subjects are conditioned and the test is influenced by self-reflections for which these test subjects gain time.

Die Ergonomie der Einrichtung zur Erzeugung eines Beurteilungssignals herkömmlicher Vorrichtungen ist ebenfalls problematisch, weil die bisher verwendeten Schieber oder Taster den Ergonomieanforderungen nicht genügen und sich unter psycho-physiologisch Aspekten als nachteilig erweisen. Die eindimensionale Ausgestaltung solcher Schieber macht außerdem die überlagerte Äußerung zu unterschiedlichen Beurteilungskriterien bzw. Beurteilungswertpaaren (wie z. B. laut/leise - hell/dunkel) mit Einhandbedienung unmöglich.The ergonomics of the device for generating a judgment signal of conventional devices is also problematic because the slides or buttons previously used do not meet the ergonomic requirements and prove to be disadvantageous from a psycho-physiological point of view. The one-dimensional design of such sliders also makes the overlaid utterance on different assessment criteria or assessment value pairs (such as loud / quiet - light / dark) impossible with one-hand operation.

Bei den vorbekannten Systemen ist weiterhin eine gesonderte Textausgabe im Bereich des Schiebers vorgesehen, welche es erforderlich macht oder die Testperson zumindest dazu verführt, den Augenkontakt von dem eigentlichen Filmereignis wegzunehmen, um nach möglichen Angaben auf der Textausgabe zu schauen, vor allem aber auch um die Position des Schiebers oder die Stellung der Taster zu überprüfen.In the known systems, a separate text output is also provided in the area of the slide, which makes it necessary or at least tempts the test person to remove eye contact from the actual film event in order to look for possible information on the text output, but above all also about the Check the position of the slide or the position of the buttons.

Ein weiterer Nachteil herkömmlicher derartiger Systeme besteht darin, daß eine Überprüfung der Reaktionskurve bezogen auf den einzelnen Teilnehmer nach Ablauf des Tests mit einer neuerlichen simultanen Einspeisung der aufgezeichneten Reaktionskurve parallel zu dem zu testenden Videospot, um auf diese Weise eine Stellungnahme zu exponierten Reaktionen der Testperson einzuholen, nicht möglich ist. Ebenso ist es nicht möglich, multisequentielle Tests durchzuführen, um interaktive Reaktionen zu testen.Another disadvantage of conventional systems of this type is that a check of the reaction curve in relation to the individual participant after the test has ended with a new simultaneous feeding of the recorded reaction curve parallel to the video spot to be tested, in order in this way to obtain an opinion on exposed reactions of the test person , not possible. Likewise, it is not possible perform multi-sequential tests to test interactive reactions.

Letztlich ermöglichen es vorbekannte Systeme der in Betracht stehenden Art auch nicht, eine Tonwiedergabe in Stereo vorzusehen, da eine Tonspur anderweitig benötigt wird.Ultimately, previously known systems of the type under consideration also do not make it possible to provide a sound reproduction in stereo, since a sound track is otherwise required.

Eine Vorrichtung der in Betracht stehenden Art ist z. B. auch aus der DE-PS 37 38 336 bekannt. Auch diese Vorrichtung weist den Nachteil auf, daß für alle Testpersonen nur ein Bildschirm zur Verfügung steht, so daß die Konzentration der Einzeltestpersonen nicht optimal ist und die Gefahr einer Ergebnisverfälschung durch wechselseitige Beeinflussung der Testpersonen besteht. Eine wenig differenzierende, sehr grobe Eingabetastatur ermöglicht keine kontinuierliche, differenzierte Erfassung der Gemütsäußerung und erfordert eine relativ große Aufmerksamkeit bei der Bedienung, so daß die Gefahr einer Ablenkung der Testperson vom eigentlichen Filmereignis besteht. Letztlich ist die Soziodemographie der Testpersonengruppe bei diesem Gerät nur durch gesonderte Befragung zu ermitteln und kann nicht im Zuge des Tests durch interaktive Befragung erfaßt werden.A device of the type in question is e.g. B. also known from DE-PS 37 38 336. This device also has the disadvantage that only one screen is available for all test subjects, so that the concentration of the individual test subjects is not optimal and there is a risk of results being falsified by the test subjects interacting with one another. A little differentiating, very rough input keyboard does not allow a continuous, differentiated recording of the expression of the mind and requires a relatively large amount of attention during operation, so that there is a risk of distracting the test person from the actual film event. Ultimately, the socio-demography of the group of test subjects can only be determined with this device by means of a separate survey and cannot be recorded in the course of the test by means of an interactive survey.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, die bekannten Systeme so zu verbessern, daß die Kommunikationsmöglichkeiten zwischen der Vorrichtung und der Testperson technisch verbessert werden, daß eine sehr individuelle Erfassung der Reaktion einzelner Testpersonen ermöglicht wird, und daß durch eine verbesserte Gesamtkonzeption auch der marktforscherische Wert der mit einer solchen Vorrichtung erzielbaren Testergebnisse optimiert wird.Proceeding from this, the object of the invention is to improve the known systems in such a way that the communication possibilities between the device and the test person are technically improved, that a very individual recording of the reaction of individuals Test persons is made possible, and that the improved overall concept also optimizes the market research value of the test results that can be achieved with such a device.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei einer gattungsgemäßen Vorrichtung jeder einzelnen Testperson ein individuell für diese abspielbarer Videorekorder mit einem Bildschirm zugeordnet ist, und daß die Einrichtung zur Erzeugung eines Beurteilungssignals durch einen feinstufig oder stufenlos ein Signal erzeugenden Schwenkhebel gebildet wird.This object is achieved in that, in a generic device, each individual test subject is assigned an individually playable video recorder with a screen, and that the device for generating a judgment signal is formed by a fine-level or continuously variable signal lever.

Durch diese Ausgestaltung wird ein individueller Testbeginn und Testablauf für jede Testperson einer Testgruppe ermöglicht. Schnell reagierende Testpersonen können den Test ohne Verzögerung und ohne damit einhergehende Beeinflussung des Testergebnisses spontan reagierend absolvieren. Der erfindungsgemäß vorgesehene Schwenkhebel als Eingabeeinrichtung weist erhebliche ergonomische Vorteile auf, insbesondere läßt er sich mit einer Hand leicht und entspannt bedienen und erfordert keine visuelle Beobachtung bei der Eingabe.This configuration enables an individual test start and test sequence for each test person in a test group. Quickly responding test subjects can take the test spontaneously without delay and without influencing the test result. The swivel lever provided according to the invention as an input device has considerable ergonomic advantages, in particular it can be operated easily and relaxed with one hand and does not require any visual observation when entering.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß der Hebel nach Art eines Joy-Stick in zwei Ebenen schwenkbar ist und korrespondierend zwei Signalarten einander Überlagerbar erzeugt. Die Bewegungen können variabel bedämpft werden, so daß ungewollte Eingaben durch eine taktile Rückmeldung weitestgehend vermieden werden. Es kann also mit einer derartigen Eingabeeinrichtung ein viel breiteres Gefühlsäußerungsspektrum erfaßt werden als mit nur einer eindimensional arbeitenden, positive und negative Bewertungen erfassenden Eingabeeinrichtung. Beispielsweise kann die Testperson gleichzeitig die Helligkeit des Bildes und die Lautstärke des Tons beurteilen, welche sich ja bei einem Videospot zu einem Gesamteindruck ergänzen, den die Testperson insgesamt positiv oder negativer empfindet. Es ist also eine wesentlich differenzierte Erfassung eines Endurteils möglich.In a further embodiment of the invention it is provided that the lever can be pivoted in two planes in the manner of a joy stick and correspondingly generates two types of signals that can be superimposed on one another. The movements can be dampened variably, so that unwanted entries are largely avoided by tactile feedback. So it can with such Input device a much broader range of expressions of feeling can be recorded than with only one-dimensionally working input device which records positive and negative evaluations. For example, the test person can simultaneously assess the brightness of the image and the volume of the sound, which, in the case of a video spot, add up to an overall impression that the test person feels positive or negative overall. A significantly differentiated recording of an end judgment is therefore possible.

Günstigerweise ist vorgesehen, daß der Hebel eine aktivierbare variable Rückstelleinrichtung in die Nullage aufweist. Dies ist z. B. bei Tests von wesentlicher Bedeutung, welche eine zeitlich dominante Willensäußerung erfordern, d. h. die Testperson muß ständig willkürlich eine Willensäußerung durch Druckausübung von sich geben, da andernfalls der Hebel selbstätig in die Nullstellung zurückkehrt.It is advantageously provided that the lever has an activatable variable return device in the zero position. This is e.g. B. in tests essential, which require a temporally dominant expression of will, d. H. the test person must constantly express himself voluntarily by exerting pressure, otherwise the lever will automatically return to the zero position.

Die Rückstelleinrichtung kann entweder durch eine Topffeder oder aber z. B. durch in zwei einander entgegengesetzte Richtungen ziehende Zugfedern gebildet werden. Hierdurch wird ein definierter Nullpunkt bzw. eine Rückstellung in die Nullage erreicht.The reset device can either by a pot spring or z. B. are formed by pulling in two opposite directions tension springs. A defined zero point or a return to the zero position is hereby achieved.

Mit Vorteil ist der Hebel mit einer mechanischen, taktil erkennbaren Nullpunktmarkierung versehen. Dabei kann vorgesehen sein, daß für die X- und Y-Richtung eine gesonderte Nullpunktmarkierung aktiviert wird. Dies ermöglicht es der Testperson, ohne den Augenkontakt zu dem zu testenden Videospot zu unterbrechen, die Position des Hebels zu erkennen und insbesondere zu realisieren, wenn das Beurteilungssignal sich in seiner Richtung ändert.The lever is advantageously provided with a mechanical, tactile recognizable zero mark. It can be provided that a separate zero point marking is activated for the X and Y directions. This enables the test subject to make no eye contact to interrupt the video spot to be tested, to recognize the position of the lever and, in particular, to realize it when the evaluation signal changes its direction.

Es kann vorteilhaft sein, daß eine der Bewegungsebenen des Hebels mechanisch blockierbar ist, wenn für einen bestimmten Test nur im wesentlichen ein einziges Beurteilungskriterium abgefragt wird. Dies kann günstigerweise so realisiert werden, daß eine mechanische Blockierung durch das Einschieben einer U-förmigen Kulisse derart vorgesehen ist, daß die Längsausnehmung der U-förmigen Kulisse die zugelassene Bewegungsrichtung definiert.It can be advantageous that one of the movement planes of the lever can be mechanically blocked if only a single assessment criterion is queried for a particular test. This can expediently be implemented in such a way that mechanical blocking by inserting a U-shaped link is provided in such a way that the longitudinal recess of the U-shaped link defines the permitted direction of movement.

Für manche Testzwecke ist es vorteilhaft, daß zusätzlich zu der Einrichtung für die manuelle Signalerzeugung, insbesonder zum Setzen von Markierungen oder dergleichen, ein Fußpedal als Eingabeeinrichtung vorgesehen ist. Hierdurch kann die Testperson in einfacher Weise z. B. das Überschreiten bestimmter vorher abgefragter, zu einem bestimmten Zeitpunkt individuell empfundener Grenzen eingeben.For some test purposes it is advantageous that in addition to the device for manual signal generation, in particular for setting markings or the like, a foot pedal is provided as an input device. As a result, the test person can in a simple manner, for. B. Enter the exceeding of certain previously queried, individually perceived limits at a certain time.

Günstigerweise ist eine Schaltungsanordnung zum Einblenden der X- und/oder Y-Position des Hebels am horizontalen und/oder vertikalen Bildrand des Bildschirms vorgesehen. Hierdurch hat die Testperson eine Rückkontrolle über die von ihr eingestellte Hebelposition und damit letztlich auch die augenblickliche Beurteilung, ohne daß der Blickkontakt zum Bildschirm auch nur kurzzeitig unterbrochen werden müßte.A circuit arrangement is advantageously provided for showing the X and / or Y position of the lever on the horizontal and / or vertical image edge of the screen. As a result, the test person has a back control over the lever position he has set and thus ultimately also the instantaneous assessment, without the eye contact with the screen at all should be interrupted briefly.

Ein Lichtgriffel zum Einlesen von Informationen über ein auf dem Bildschirm ausgegebenes Auswahl-Tableau ermöglicht eine besonders einfache und bequeme Interaktion der Testperson mit der Test-Vorrichtung und ermöglicht auch die Erfassung soziodemographischer Daten unmittelbar im Zusammenhang mit dem Testvorgang.A light pen for reading information via a selection panel displayed on the screen enables a particularly simple and convenient interaction of the test person with the test device and also enables the acquisition of sociodemographic data directly in connection with the test process.

Günstigerweise ist eine Synchronisations-Schaltungsanordnung zur Synchronisation des Videorekorders nach Maßgabe der Datenverarbeitungs- und Speichereinrichtung vorgesehen. Solche Synchronisations-Schaltungsanordnungen sind, z. B. in Form sogenannter Genlock-Karten, marktfertig und ausgereift verfügbar. Hierdurch wird der zeitliche Ablauf und die zeitliche Kodierung und Steuerung des Videorekorders bzw. des FBAS-Videosignals des Videorekorders mit der Datenverarbeitungseinrichtung erreicht.A synchronization circuit arrangement for the synchronization of the video recorder is advantageously provided in accordance with the data processing and storage device. Such synchronization circuit arrangements are e.g. B. in the form of so-called genlock cards, market ready and mature available. In this way, the chronological sequence and the temporal coding and control of the video recorder or the composite video signal of the video recorder is achieved with the data processing device.

Weiterhin ist mit Vorteil eine Schaltungsanordnung zum Einblenden von Texten und/oder Graphikbildern in den Bildschirm vorgesehen. Hierdurch werden herkömmlicherweise vorgesehene gesonderte Textausgabeeinrichtungen vermieden, so daß der diesbezügliche bauliche Aufwand vermindert wird, vor allem aber bleibt auch hierdurch die Konzentration der Testperson auf dem Bildschirm voll erhalten.A circuit arrangement for superimposing texts and / or graphic images on the screen is also advantageously provided. As a result, conventionally provided separate text output devices are avoided, so that the related structural outlay is reduced, but above all, the test subject's concentration on the screen is also fully retained.

Zur Erzielung einer besonders guten Bildqualität für derartige Einblendungen ist eine Abschalteinrichtung für die Zeilensprungabtast-Schaltungsanordnung für das Videorekorder-Videosignal der Datenverarbeitungs- und Speichereinrichtung vorgesehen.A switch-off device is used to achieve a particularly good image quality for such insertions for the interlaced scan circuitry for the VCR video signal of the data processing and storage device.

Letztlich ist es noch vorteilhaft, eine Zeit-Code-Leseeinrichtung zur Erfassung von absoluten und relativen Zeitcode-Signalen (SMPTE/EBU - und CTL-Signalen) vorzusehen, so daß bei einem Ausfall der absoluten Zeitcodierung noch eine Erkennung der Relativposition möglich ist.Ultimately, it is also advantageous to provide a time code reading device for detecting absolute and relative time code signals (SMPTE / EBU and CTL signals), so that if the absolute time coding fails, the relative position can still be detected.

Letztlich ermöglicht es die erfindungsgemäße Ausgestaltung noch mit Stereoton zu arbeiten und die hieraus resultierenden spezifischen Eindrücke dementsprechend auch zu erfassen.Ultimately, the configuration according to the invention enables stereo sound to be used and the resulting specific impressions to be recorded accordingly.

Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher beschrieben. Dabei zeigen:

Aus Fig. 1 ist ersichtlich, daß die erfindungsgemäße Vorrichtung eine zentrale Datenverarbeitungs- und Speichereinrichtung 1 umfaßt sowie eine Mehrzahl von Arbeitsplätzen 2, 3, 4 für je eine Testperson umfassend jeweils einen individuellen Videorekorder 5, 6, 7 und einen mit diesem verbundenen individuellen Bildschirm 8, 9, 10. Wenn im Ausführungsbeispiel drei Arbeitsplätze 2 bis 4 dargestellt sind, so dient dies nur der Veranschaulichung. Tatsächlich wird man bei der Realisierung in der Praxis eine größere Anzahl von Arbeitsplätzen in einem Testraum vorsehen.From Fig. 1 it can be seen that the device according to the invention comprises a central data processing and storage device 1 and a plurality of workstations 2, 3, 4 for each test person each comprising an individual video recorder 5, 6, 7 and an individual screen connected to this 8, 9, 10. If three workplaces 2 to 4 are shown in the exemplary embodiment, this is only for illustration. In fact, in practice, a larger number of workplaces will be provided in a test room.

Jedem Arbeitsplatz 2 bis 4 ist weiterhin ein Schwenkhebel 11, 12, 13 zugeordnet, mit dessen Hilfe die jeweilige Testperson wie vorstehend im einzelnen beschrieben auf das auf den Bildschirmen 8 bis 10 gezeigte Geschehen reagieren bzw. dieses beeinflussen kann.A swiveling lever 11, 12, 13 is also assigned to each work station 2 to 4, with the aid of which the respective test person can react or influence the events shown on the screens 8 to 10 as described in detail above.

Die verschiedenen Schwenkhebel 11 bis 13 sind jeweils identisch aufgebaut. Dementsprechend wird nachfolgend nur einer dieser Schwenkhebel zusammen mit dem mit ihm verbundenen Eingabeeinrichtungen näher beschrieben.The different pivot levers 11 to 13 are each constructed identically. Accordingly, only one of these pivot levers will be used together with it connected input devices described in more detail.

Eine derartige Schwenkhebelanordnung umfaßt ein Gehäuse 14 mit einer Grundplatte 15 sowie an der Grundplatte 15 über Schrauben 16 höheneinstellbare und über Schrauben 17 festlegbare Hartgummi-Füße 18.Such a swivel lever arrangement comprises a housing 14 with a base plate 15 and hard rubber feet 18 which can be adjusted in height on the base plate 15 by means of screws 16 and fixed by means of screws 17.

An der Oberseite des Gehäuses 14 ist zur Abdeckung eine Kunststoffmanschette 19 vorgesehen, deren oberes verjüngtes Ende 20 einen oberen Hebelabschnitt 21 umgibt, an dessen oberen Ende ein Betätigungsknauf 22 ergonomisch geformt befestigt ist.On the top of the housing 14, a plastic sleeve 19 is provided for covering, the upper tapered end 20 of which surrounds an upper lever section 21, at the upper end of which an actuating knob 22 is attached in an ergonomically shaped manner.

An dem unteren Ende 23 des Schaftabschnitts 21 sind in einem Winkel von 90° zueinander vier Kraftübertragungsarme 24 angeordnet, an deren unterem, abgekröpften Ende 25 jeweils ein Kugelgelenkkopf 26 mittels eines Gewindeabschnitts 27 und Schrauben 28 festgelegt ist.At the lower end 23 of the shaft section 21, four force transmission arms 24 are arranged at an angle of 90 ° to one another, at the lower, bent end 25 of which a ball joint head 26 is fixed by means of a threaded section 27 and screws 28.

Über die Kugelgelenkkugeln 26 sind Kugelgelenkpfannen 29 mit Befestigungsansätzen 30 gestülpt. An den Befestigungsansätzen 30 sind zwei Kraftübertragungstangen 31 angesetzt, an deren unterem Ende jeweils wieder eine Kugelgelenkpfanne 32 anschließt. Insgesamt sind zwei derartige Kraftübertragungsstangen 31 vorgesehen. An den jeder Kraftübertragungsstange 31 etwa gegenüberliegenden Kraftübertragungsarmen 24 sind jeweils Gasdämpfer 33 über endseitige Kugelpfannen angelenkt. Diese Gasdämpfer 33 sind in der Zeichnung nur schematisch angedeutet. Sie dienen dazu, die über den Hebelabschnitt 21 übertragene Schwenkbewegung, welche von den Kraftübertragungsstangen 31 weitergeleitet wird, gemäß einer definierten Dämpfungscharakteristik zu dämpfen, um so der Bedienungsperson ein Widerstandsgefühl zu vermitteln und ihr eine dosierte Betätigung zu ermöglichen.Ball joint sockets 29 with fastening projections 30 are placed over the ball joint balls 26. Two power transmission rods 31 are attached to the attachment lugs 30, and a ball joint socket 32 is connected to the lower end of each. A total of two such power transmission rods 31 are provided. At each power transmission rod 31 approximately opposite power transmission arms 24 gas dampers 33 are articulated via ball sockets at the ends. These gas dampers 33 are only indicated schematically in the drawing. They are used over the lever section 21 transmitted pivoting movement, which is transmitted from the power transmission rods 31, to dampen according to a defined damping characteristic, so as to convey a feeling of resistance to the operator and to enable him to perform it in a metered manner.

An dem unteren Ende 23 des Schaftabschnitts 21 unterhalb der Arme 24 ist über Madenschrauben 34 ein Kreuzkugelgelenk 35 üblicher Bauart befestigt, welches zwei gegeneinander um Schwenkachsen 36, 37 verschwenkbare Abschnitte 38, 39 umfaßt. Der Abschnitt 39 ist über Madenschrauben 40 mit einem zweiten Schaftabschnitt 41 verbunden.At the lower end 23 of the shaft section 21 below the arms 24, a cross-ball joint 35 of a conventional type is attached via grub screws 34, which comprises two sections 38, 39 which can be pivoted relative to one another about pivot axes 36, 37. The section 39 is connected to a second shaft section 41 via grub screws 40.

Unterhalb des Kreuzkugelgelenks 35, welches Schwenkbewegungen des Schaftabschnitts 21 in der Zeichenebene in Figur 2 und senkrecht hierzu zuläßt, ist eine Anschlagscheibe 42 aus Kunststoff über einen Gewindeabschnitt 43 des zweiten Schaftabschnitts 41 und eine Kontermutter 44 höhenverstellbar befestigt. Je nach Höheneinstellung der Anschlagscheibe 42 begrenzt diese die Schwenkbewegung der Arme 24, indem deren unteres Ende 25 an der Scheibe 42 anschlägt, wenn der erste Schaftabschnitt 21 verschwenkt wird.Below the cross-ball joint 35, which permits pivoting movements of the shaft section 21 in the plane of the drawing in FIG. 2 and perpendicularly thereto, a plastic stop disk 42 is fastened in a height-adjustable manner via a threaded section 43 of the second shaft section 41 and a lock nut 44. Depending on the height setting of the stop disk 42, this limits the pivoting movement of the arms 24, in that the lower end 25 thereof strikes the disk 42 when the first shaft section 21 is pivoted.

Die Kraftübertragungsstangen 31, welche die Schwenkbewegung des Schaftabschnitts 21 in zwei durch das Kreuzkugelgelenk 35 definierte, zueinander senkrechte Bewegungsrichtungen (X-Richtung; Y-Richtung) übertragen, greifen an je einer Eingabeeinrichtung 45 an, welche nachfolgend in Verbindung mit den Figuren 4 bis 7 näher beschrieben wird.The force transmission rods 31, which transmit the pivoting movement of the shaft section 21 in two mutually perpendicular directions of movement (X direction; Y direction) defined by the cross-ball joint 35, each engage an input device 45, which is described in more detail below in connection with FIGS. 4 to 7.

Jede Eingabeeinrichtung 45 umfaßt eine Bodenplatte 46, welche über Schrauben (vgl. Figur 2) mit der Bodenplatte 15 des Gehäuses 14 verbunden ist. An der Bodenplatte 46 sind im Abstand voneinander zwei zueinander parallele zur Bodenplatte 46 senkrechte Trägerplatten 47, 48 angeschweißt, wobei an der Oberseite der Trägerplatte 48 wiederum ein L-förmiges Halteteil 49 angeschweißt ist.Each input device 45 comprises a base plate 46 which is connected to the base plate 15 of the housing 14 by means of screws (cf. FIG. 2). Two support plates 47, 48, which are parallel to one another and perpendicular to the base plate 46, are welded to the base plate 46 at a distance from one another, an L-shaped holding part 49 being welded to the top of the support plate 48.

An dem kürzeren Schenkel 50 des Halteteils 49 ist ein Drehpotentionmeter 51 befestigt. Dieses ist über eine Ausgleichsscheibenanordnung 52 mit einem Schwenkbolzen 53 verbunden, deren Schwenklagerbohrungen 54 der Trägerplatte 48 und Schwenklagerbohrungen 55 der Trägerplatte 47 schwenkbar gelagert ist. Mit dem Schwenkbolzen 53 ist drehfest über eine Gewindebohrung 56 mit einer entsprechenden Madenschraube 57 (vgl. Figur 6 und 7) ein Mitnehmerteil 58 verbunden. Dieses umfaßt einen Übertragungsarm 59 mit einem Langloch 60 zur Verbindung mit dem unteren Kugelgelenk 32 der Übertragungsgestänge 31 und einen in einem 90° Winkel hierzu angeordneten Mitnehmerarm 61, der an seiner Unterseite einen Mitnehmerzapfen 62 (vgl. Fig. 7) mit einer aufgestecken Hülse 63 (vgl. Fig. 4) aufweist.A rotation potentiometer 51 is attached to the shorter leg 50 of the holding part 49. This is connected via a shim arrangement 52 to a pivot pin 53, the pivot bearing bores 54 of the carrier plate 48 and pivot bearing bores 55 of the carrier plate 47 are pivotally mounted. A driver part 58 is connected to the pivot pin 53 in a rotationally fixed manner via a threaded bore 56 with a corresponding grub screw 57 (see FIGS. 6 and 7). This includes a transmission arm 59 with an elongated hole 60 for connection to the lower ball joint 32 of the transmission linkage 31 and a driving arm 61 arranged at a 90 ° angle thereto, which has a driving pin 62 on its underside (see FIG. 7) with an attached sleeve 63 (see FIG. 4).

Mit den beiden Armen 60, 61 ist in deren Kreuzungsbereich eine Scheibe 64 verbunden, die in ihrem Scheitelbereich eine Nut 65 (vgl. Fig. 6) aufweist, welche zusammenwirkt mit einer Rollkugel 66, die in einem Träger 67 angeordnet ist. Der Träger 67 durchsetzt den horizontalen Schenkel 68 des L-förmigen Halteteils 49 und kann mit Hilfe einer Feststellmutter 69, eines Außengewindes 70 und eines Schraubendreher-Betätigungsschlitzes 71 in der Höhe verstellt werden. Auf diese Weise ist es möglich, eine taktile Nullpunktserkennung mit einstellbarer Kontaktintensität zu realisieren.A disk 64 is connected to the two arms 60, 61 in their intersection area and has a groove 65 in its apex area (cf. FIG. 6), which interacts with a trackball 66, which is arranged in a carrier 67. The carrier 67 passes through the horizontal leg 68 of the L-shaped holding part 49 and can be adjusted in height by means of a locking nut 69, an external thread 70 and a screwdriver actuation slot 71. In this way it is possible to realize tactile zero point detection with adjustable contact intensity.

Die Schwenkbewegung des Mitnehmerarms 61 und damit des Schwenkhebelabschnitts 21 wird gedämpft durch Gasfedern 33, deren eines Ende mit der Gelenkkugel 26 des Übertragungsarms 24 verbunden ist, und deren anderes Ende an einer Gelenkkugel 72 (vgl. Fig. 3) eines starren Haltearmes 73 angreifen.The pivoting movement of the driving arm 61 and thus of the pivoting lever section 21 is damped by gas springs 33, one end of which is connected to the joint ball 26 of the transmission arm 24 and the other end of which engage a joint ball 72 (cf. FIG. 3) of a rigid holding arm 73.

Um die Schwenkachse, die durch den Schwenklagerbolzen 53 definiert wird, verschwenkbar gelagert sind auch zwei Federhaltearme 74, 75 (vgl. Fig. 3), welche in ihrem Schwenkweg durch einen in deren Mitte angeordneten Anschlagbolzen 76 begrenzt sind, der in den Halteteilen 47, 48 festgelegt ist (vgl. Fig. 4 und 5).Two spring holding arms 74, 75 (cf. FIG. 3) are also pivotably mounted about the pivot axis, which is defined by the pivot bearing pin 53, and are limited in their pivoting path by a stop pin 76 arranged in the middle thereof, which is located in the holding parts 47, 48 is fixed (see FIGS. 4 and 5).

Jeder Federhaltearm 74, 75 weist eine Mehrzahl von Halteausnehmungen 77 für die Enden 78 einer Schraubenfeder 79 auf, welche die Federhaltearme 74, 75 jeweils bei Auslenkung eines der Federhaltearme 74, 75 über den Mitnahmebolzen 62 in Richtung auf den Anschlagbolzen 76 drückt und somit eine definierte Rückstellkraft ausgehend von beiden Auslenkungsrichtungen bezogen auf die Nulllage und eine definierte Rückstellung des Schwenkarmabschnitts 21 in die Nullstellung gewährleistet.Each spring holding arm 74, 75 has a plurality of holding recesses 77 for the ends 78 of a helical spring 79, which presses the spring holding arms 74, 75 each time one of the spring holding arms 74, 75 is deflected via the driving pin 62 in the direction of the stop pin 76 and thus defines a defined one Restoring force based on both directions of deflection ensures the zero position and a defined return of the swivel arm section 21 to the zero position.

Falls es gewünscht wird, eine Schwenkbewegung des Schwenkhebels 11 in nur einer Ebene zuzulassen, kann die Schwenkbewegung in der jeweils anderen Ebene dadurch blockiert werden, daß eine in Figur 2 nur angedeuteter Arretierstift 80 mit einem äußeren Betätigungsknopf in eine Bohrung eines Mitnehmerarms 61 eingeschoben wird, so daß hierdurch eine Schwenkbewegung unterbunden wird.If it is desired to allow a pivoting movement of the pivoting lever 11 in only one plane, the pivoting movement in the respective other plane can be blocked by inserting a locking pin 80, which is only indicated in FIG. 2, with an outer actuating button into a bore of a driving arm 61, so that a pivoting movement is prevented.

Aufgrund der vorstehend beschriebenen Übertragung der Schwenkbewegung des Schwenkhebels 11 auf die Potentiometer 51 wird der Widerstand der Potentiometer 51 verändert, so daß auf diese Weise die mechanische Schwenkbewegung in ein elektrisches Signal umgesetzt wird, dessen Größe der Schwenkauslenkung entspricht.Due to the transmission of the pivoting movement of the pivoting lever 11 to the potentiometer 51 described above, the resistance of the potentiometer 51 is changed, so that in this way the mechanical pivoting movement is converted into an electrical signal, the size of which corresponds to the pivoting deflection.
