Description

Die Erfindung betrifft einen Fahrtschreiber für Kraftfahrzeuge mit einem Einbaugehäuse, in welchem ein für die Verwendung von blattförmigen Aufzeichnungsträgern ausgerüstetes Registrieraggregat und ein Anzeigeinstrument angeordnet sind.The invention relates to a tachograph for motor vehicles with a built-in housing, in which a registration unit equipped for the use of sheet-like recording media and a display instrument are arranged.

Bei den herkömmlichen Fahrtschreibern sind bekanntlich die als Aufzeichnungsträger dienenden Diagrammscheiben einem aufklappbaren Deckel zugeordnet, und zwar derart, daß eine eingelegte Diagrammscheibe in allen für den Fahrtschreiber in Frage kommenden Einbausituationen bei geöffnetem Deckel dem Betrachter zugewandt ist. Das heißt, innerhalb des Deckels ist außer verschiedenen anderen Funktionsgruppen, insbesondere verschiedenen Anzeigemitteln, ein Laufwerk angeordnet, welches eine an der als Registrierunterlage dienenden Rückseite des Deckels zugängliche, mit einem Zentrier- und Mitnahmedorn versehene Diagrammscheibenaufnahme uhrzeitrichtig antreibt. Dieses Konzept gewährleistet ein relativ problemloses Handhaben des Fahrtschreibers beim stichprobenweisen Kontrollieren der Aufzeichnungen und beim Wechseln der Diagrammscheiben. Die Architektur der üblichen Fahrtschreiber ist ferner dadurch gekennzeichnet, daß die Querschnittsfläche quer zur Geräteachse nur wenig größer ist als der Durchmesser der verwendeten Diagrammscheiben. Diese Minimierung des Einbauquerschnitts läßt das Gerät für den Betrachter optisch vorteilhafter erscheinen und gestattet es, den Fahrtschreiber auch in relativ schmale Armaturenbretter einbauen zu können.In the conventional tachographs, the chart disks serving as recording media are known to be assigned to a hinged cover, in such a way that an inserted chart disk faces the viewer in all installation situations that are possible for the tachograph with the lid open. This means that, in addition to various other function groups, in particular various display means, a drive is arranged inside the cover, which drives a diagram disc holder accessible on the back of the cover, which serves as a registration document, and provided with a centering and driving mandrel at the correct time. This concept ensures that the tachograph can be handled relatively easily when checking the recordings on a random basis and when changing the diagram disks. The architecture of the usual tachographs is further characterized in that the cross-sectional area transverse to the device axis is only slightly larger than the diameter of the diagram disks used. This minimization of the installation cross section makes the device appear optically more advantageous for the viewer and allows the tachograph to be installed in relatively narrow dashboards.

Die Folge dieser Architektur ist ein stockwerkartiger Aufbau des Fahrtschreibers und Raumbedarf in Achsrichtung, d. h. beachtliche Bautiefe. Hierdurch ergeben sich beim derzeitigen Gestaltungstrend von Armaturenbrettern bzw. Instrumentenkonsolen von Nutzfahrzeugen erhebliche Einbauschwierigkeiten, insbesondere wenn der Fahrtschreiber zur Erzielung einer gemeinsamen Frontfläche für alle vorgesehenen Instrumente in die relativ flach gestalteten Instrumentenkonsolen nicht mehr "aufgesetzt" sondern "versenkt" eingebaut werden muß. Im übrigen stellt eine derartige Anpassung herkömmlicher Fahrtschreiber an ein gegebenes Armaturenbrettdesign unter Verwendung geeigneter Halter und Frontblenden eine recht unbefriedigende und aufwendige Hilfsmaßnahme dar. Schwierigkeiten und Unzulänglichkeiten hinsichtlich der Handhabung der Diagrammscheiben entstehen außerdem in der bevorzugten Einbausituation des Fahrtschreibers in Blickrichtung des Fahrers, d. h. im Bereich des Lenkrades, wo verständlicherweise der für das Aufschwenken des Deckels erforderliche Raum am wenigstens gegeben ist.The consequence of this architecture is a storey-like structure of the tachograph and space requirements in the axial direction, ie considerable depth. This results in considerable installation difficulties in the current trend in the design of dashboards or instrument panels of commercial vehicles, in particular when the tachograph is used Achievement of a common front surface for all the intended instruments in the relatively flat instrument consoles no longer has to be "put on" but "recessed". Moreover, such an adaptation of conventional tachographs to a given dashboard design using suitable holders and front panels is a rather unsatisfactory and complex auxiliary measure. Difficulties and inadequacies with regard to the handling of the diagram disks also arise in the preferred installation situation of the tachograph in the driver's line of sight, ie in the area the steering wheel, where, understandably, the space required for pivoting the cover is at least given.

Unter diesen Umständen ist es naheliegend, diese Probleme dadurch zu lösen, daß der Fahrtschreiber in ein im Armaturenbrett verbleibendes Anzeigeinstrument und ein räumlich von diesem getrennt angeordnetes, in geeigneter Weise datengekoppeltes Registrieraggregat aufgeteilt wird. Eine derartige Lösung hat jedoch den entscheidenden Nachteil, daß je nach Fahrzeugtyp die Anbringung des Registrieraggregates im Fahrerhaus stark variieren kann. Dies wäre, abgesehen davon, daß die Fahrer ohnehin zu einer von den gewohnten Handgriffen im Breich der Instrumentenkonsole völlig abweichende Handhabung beim Wechseln der Aufzeichnungsträger gezwungen wären, wenig benutzerfreundlich und würde in vielen Fällen nicht nur neue Installationsprobleme hervorrufen, sondern auch die Gefahr in sich bergen, daß das Eingeben oder Wechseln der Aufzeichnungsträger vergessen wird.Under these circumstances, it is obvious to solve these problems by dividing the tachograph into a display instrument remaining in the dashboard and into a suitably data-coupled registration unit, which is arranged spatially separated from it. However, such a solution has the decisive disadvantage that, depending on the vehicle type, the mounting of the registration unit in the driver's cab can vary widely. Apart from the fact that the drivers would be forced to handle the changing of the recording media completely differently from the usual manipulations in the area of the instrument console, this would not be user-friendly and in many cases would not only cause new installation problems, but would also involve the danger that the entry or changing of the recording medium is forgotten.

Der vorliegenden Erfindung war somit die Aufgabe gestellt, einen Fahrtschreiber zu schaffen, der, was die Handhabung der Aufzeichnungsträger anbelangt, keine räumliche Umorientierung der Fahrer erfordert, bessere Handhabungsbedingungen bietet, die gewohnte, formatfüllende Anzeige aufweist und die genannten Einbauprobleme weitgehend vermeidet.The object of the present invention was therefore to create a tachograph which, as far as the handling of the recording media is concerned, does not require a spatial reorientation of the driver, offers better handling conditions, has the usual format-filling display and largely avoids the installation problems mentioned.

Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, daß an der für die Anzeige wenigstens der Geschwindigkeit vorgesehenen Frontwand des Fahrtschreibers mindestens ein Schlitz für die Eingabe und Ausgabe der Aufzeichnungsträger vorgesehen ist und daß Führungsmittel und eine Transportvorrichtung vorgesehen sind, die einen durch den Schlitz eingegebenen Aufzeichnungsträger selbsttätig in seine Registrierposition in einer zur Frontwand im wesentlichen paralleler Ebene umlenken.The solution to this problem is characterized in that at least one slot for the input and output of the recording medium is provided on the front wall of the tachograph intended to display at least the speed and that guide means and a transport device are provided which automatically operate a recording medium entered through the slot deflect into its registration position in a plane substantially parallel to the front wall.

Einzelheiten der erfindungsgemäßen Lösung beschreiben die Unteransprüche.Details of the solution according to the invention describe the subclaims.

Die gefundene Fahrtschreiberarchitektur wird allen Teilbereichen der gestellten Aufgabe gerecht, insbesondere bietet sie mit dem selbsttätigen Einziehen und Ausgeben eine vereinfachte Handhabung beim Wechseln der Aufzeichnungsträger. Vorteilhaft ist ferner, daß die unmittelbare räumliche Zuordnung des Registrieraggregates zu einem Anzeigeinstrument, das in herkömmlicher Weise über die momentane Geschwindigkeit, die Tageszeit und die zurückgelegte Strecke informiert und somit dem Charakter des herkömmlichen Fahrtschreibers entspricht, erhalten bleibt. Außerdem bietet der frontseitig angeordnete Eingabeschlitz und die Gesamtarchitektur des Fahrtschreibers die Möglichkeit, eines zu den übrigen Frontflächen eines Armaturenbretts bündigen Einbaus und die Verwendung sozusagen als Baustein eines Armaturenbretts. Die dies ermöglichende, außergewöhnlich geringe Einbautiefe wurde erreicht durch eine konsequent flache Verteilung und Verdichtung der Bauelemente, insbesondere der verschiedenen Antriebe und der elektronischen Bauteile des Fahrtschreibers.The tachograph architecture found does justice to all sub-areas of the task, in particular it offers simplified handling when changing the recording medium with the automatic feeding and dispensing. It is also advantageous that the immediate spatial assignment of the registration unit to a display instrument, which informs in a conventional manner about the current speed, the time of day and the distance traveled and thus corresponds to the character of the conventional tachograph, is retained. In addition, the input slot arranged on the front and the overall architecture of the tachograph offer the option of installing it flush with the other front surfaces of a dashboard and using it as a component of a dashboard, so to speak. The exceptionally low installation depth that made this possible was achieved by consistently flat distribution and compression of the components, in particular the various drives and the electronic components of the tachograph.

Die Übersichtsdarstellung FIGUR 1 zeigt einen Teil eines Armaturentretts bzw. einer Instrumentenkonsole 1 mit einem ersten Abschnitt 2, in welchem verschiedene Bedienungsorgane 3 und mit einem zweiten Abschnitt 4, in welchem Anzeigeinstrumente angeordnet sind. Eine den Anzeigeinstrumenten zugeordnete, kreisförmige Fenster 5 und 6 für die Anzeigemittel eines Drehzahlmessers 57 und die Anzeigemittel eines Fahrtschreibers 6o aussparende Blende 7 ist von einer den Instrumenten gemeinsam zugeordneten Glasscheibe 8 abgedeckt. Die Geschwindigkeitsanzeigemittel des Fahrtschreibers 6o sind mit 9 und 1o, die Zeitanzeigemittel mit 11, 12 und 13 bezeichnet. Weitere Blenden 14 und 15, deren Frontflächen im wesentlichen in der Ebene der Glasscheibe 8 liegen, decken die Stoßfugen zwischen den Instrumenten ab und blenden, was nicht dargestellt ist, verschiedene in Zeilen angeordnete Funktionskontroll-­Anzeigemittel und das Streckenzählwerk 16 des Fahrtschreibers 6o aus. Ferner sind durch die eine Blende 15, die den Arbeitszeit-Einstellknöpfen 17 und 18 zugeordneten Einstellwellen hindurchgeführt, während in der anderen Blende 14 ein Ausschnitt 19 vorgesehen ist, welcher von einer schwenkbaren Klappe 2o, wenn diese geschlossen ist, bündig mit der Frontfläche der Blende 14 verdeckt ist. Dem Öffnen der Klappe 2o, die den Zugang freigibt zu Schlitzen 21 und 22, durch die die als Aufzeichnungsträger dienenden Diagrammscheiben 23 und 24 in den Fahrtschreiber eingebbar sind, dient eine durch die Blende 14 hindurchgreifende Taste bzw. ein Knebel 25. Zweckmäßigerweise wird die Taste 25 verschließbar ausgebildet sein müssen. Denkbar ist ferner, daß den Schlitzen 21 und 22 eine innerhalb des Fahrtsrhreibers angeordnete Verschließeinrichtung zugeordnet ist. In den Entnahmeposition sind die Diagrammscheiben, wie FIGUR 1 zeigt, in einer griffgünstigen Weise dem Bedienenden zugewandt.The overview FIGURE 1 shows a part of a dashboard or an instrument console 1 with a first section 2, in which various operating elements 3 and with a second section 4, in which display instruments are arranged. A circular window 5 and 6 assigned to the display instruments for the display means of a tachometer 57 and the display means of a tachograph 6o, shielding aperture 7 is covered by a glass pane 8 assigned to the instruments. The speed display means of the tachograph 6o are designated 9 and 10, the time display means 11, 12 and 13. Other panels 14 and 15, the front surfaces of which lie essentially in the plane of the glass pane 8, cover the butt joints between the instruments and, which is not shown, mask out various function control display means arranged in lines and the distance counter 16 of the tachograph 6o. Furthermore, through the one panel 15, which leads to the working time adjustment knobs 17 and 18, through adjustment shafts, while in the other panel 14 a cutout 19 is provided, which, when closed, of a pivotable flap 20, is flush with the front surface of the panel 14 is covered. To open the flap 2o, which gives access to the slots 21 and 22 through which the diagram disks 23 and 24 serving as recording media can be entered into the tachograph, a button or a toggle 25 is expediently used the key 25 will have to be lockable. It is also conceivable for the slots 21 and 22 to be assigned a closing device arranged inside the tachograph. In the removal position, the diagram disks, as FIGURE 1 shows, face the operator in a convenient manner.

Die FIGUREN 2 und 3 zeigen den erfindungsgemäßen Fahrtschreiber 6o als ein autonomes Gerät mit einem Gehäuse 26 und einer die in einem Fensterausschnitt 58 der Frontwand 59 angeordneten Anzeigemittel 9, 1o, 11, 12, 13 abdeckenden Frontscheibe 27, das in dieser Form auch als Armaturenbrettsegment oder Armaturenbrettbaustein verwendbar ist.Mit 28 und 29 sind Leuchtdioden bezeichnet, mit denen der jeweilige Zustand "belegt" oder "frei" der den Schlitzen 21 und 22 zugeordneten Diagrammscheiben-Führungsschächte 3o und 31 anzeigbar ist. Die Führungsschächte 3o und 31 werden jeweils von Platten 32, 33 und 34, 35 gebildet, die gleichzeitig als Montageplatten dienen, indem ihnen beispielsweise das Geschwindigkeitsmeßwerk 36, ein Laufwerk 37 für die Zeitanzeige, die nicht dargestellten Registrierorgane, die an Schwenkarmen 38 und 39 gelagerten, im einzelnen nicht näher bezeichneten Zentrier- und Mitnahmemittel für die Diagrammscheiben und deren Registrierantriebe zugeordnet sind.FIGURES 2 and 3 show the tachograph 6o according to the invention as an autonomous device with a housing 26 and a front pane 27 covering the display means 9, 10, 11, 12, 13 arranged in a window cutout 58 of the front wall 59, which in this form also serves as a dashboard segment or dashboard module can be used. 28 and 29 denote light-emitting diodes, with which the respective state "occupied" or "free" of the diagram disk guide shafts 3o and 31 assigned to the slots 21 and 22 can be indicated. The guide shafts 3o and 31 are each formed by plates 32, 33 and 34, 35, which also serve as mounting plates, for example by the speed measuring device 36, a drive 37 for the time display, the not shown registration elements, which are mounted on swivel arms 38 and 39 , centering and driving means for the diagram disks and their registration drives, which are not specified in detail.

Der Transport der Diagrammscheiben zu und von ihren Registrierpositionen erfolgt durch in die Führungsschächte 3o und 31 eingreifende Transportrollenpaare 4o, 41 und 42, 43, die getrieblich miteinander über Zahnräder 44 und 45 in Verbindung stehen und ausgehend von einem Motor 46 über ein Zahnradgetriebe 47, 48 angetrieben werden. Dabei dient die gestaffelte Anordnung der Transportrollenpaare 4o, 41 und 42, 43 einerseits dazu, den Abstand der Führungsschächte zueinander zu minimieren, andererseits eine möglichst gleiche Einstecklänge für beide Aufzeichnungsträger zu schaffen.The diagram disks are transported to and from their registration positions by means of transport roller pairs 4o, 41 and 42, 43 which engage in the guide shafts 3o and 31 and are connected to one another in terms of gears via gearwheels 44 and 45 and, starting from a motor 46, via a gearwheel gear 47, 48 are driven. The staggered arrangement of the pairs of transport rollers 4o, 41 and 42, 43 serves on the one hand to minimize the spacing of the guide shafts from one another, and on the other hand to create the same insertion length possible for both recording media.

Die in FIGUR 4 dargestellte Variante des erfindungsgemäßen Fahrtschreibers 6o ist mit einem LC-Display ausgerüstet, mit dem eine digitale Anzeige 49 des Uhrwerkes sowie 5o des Streckenzählers und eine quasi analoge Anzeige 51 des Geschwindigkeitsmeßwerkes erfolgt. Die Eingabe der Arbeitszeitzustände ist in Form von Tasten 52, denen beispielsweise Leuchtdioden zugeordnet sein können, realisiert.The variant of the tachograph 6o according to the invention shown in FIG. 4 is equipped with an LC display, with which a digital display 49 of the clockwork and 5o of the distance counter and a quasi-analogue display 51 of the speed measuring device take place. The input of the working time states is implemented in the form of keys 52, to which light-emitting diodes can be assigned, for example.

Die Gegenüberstellung FIGUR 5 zeigt bei einem frontflächenbündigen Einbau (Ebene A) eines herkömmlichen Fahrtschreibers und des erfindungsgemäßen Fahrtschreibers 6o, daß der Raum zwischen den Ebenen B und C, d. h. der erforderliche Einbau und der bei aufgeklapptem Deckel erforderliche Bedienungsraumbedarf des herkömmlichen Fahrtschreibers erheblich größer ist als der Raum zwischen den Ebenen D und E, der dem Bedarf des erfindungsgemäßen Fahrtschreibers 6o entspricht. Vergleichsweise zu den übrigen Kontouren der beiden Fahrtschreiber ist mit dem Maß a der jeweils gleiche Fensterausschnitt für die Anzeigemittel angegeben.The comparison FIGURE 5 shows in a flush-mounted installation (level A) of a conventional tachograph and the tachograph 6o according to the invention that the space between levels B and C, i. H. the required installation and the required operating space of the conventional tachograph when the lid is open is considerably larger than the space between levels D and E, which corresponds to the requirement of tachograph 6o according to the invention. In comparison to the other contours of the two tachographs, dimension a indicates the same window section for the display means.

Der Vollständigkeit halber sei noch erwähnt, daß insbesondere bei relativ niedrigen Armaturenbrettern auch ein "querformatiger" Einbau des erfindungsgemäßen Fahrtschreibers bei entsprechend geänderter Zuordnung der Arbeitszeiteinstellorgane denkbar ist.For the sake of completeness, it should also be mentioned that, especially with relatively low dashboards, a "landscape" installation of the tachograph according to the invention is also conceivable with a correspondingly changed assignment of the working time setting elements.

Außerdem ist es denkbar, blatt- oder kartenartige Aufzeichnungsträger zu verwenden und die Aufzeichnungen mittels eines zeitabhängig bewegten Mehrfachschreibers oder eines Thermodruckkopfes vorzunehmen.In addition, it is conceivable to use sheet-like or card-like recording media and to make the recordings by means of a time-dependent moving multi-writer or a thermal print head.
