Abstract

In order to reduce the forces required for operation and increase the bending radii possible in the laying of the cable of an operating unit with a rotary member, the rotary motion of which is converted into a reciprocating motion for at least one cable which transmits tensile and compressive forces and runs outside the centre line of the rotary member, as compared with known solutions, each cable extends approximately in the direction of its subsequent curvature, at an angle to the centre line of the rotary member, within the operating unit.

Description

Die Erfindung betrifft ein Bediengerät mit einem Drehglied, dessen Drehbewegung in eine Hubbewegung für mindestens ein Zug- und Druckkräfte übertragendes, außerhalb der Mittellängsachse des Drehgliedes verlaufendes Kabel umge­ setzt wird, das nach seinem Austritt aus dem Bediengerät einen gekrümmten Verlauf einnimmt.The invention relates to an operating device with a rotary member, whose rotary motion in a stroke motion for at least a tensile and compressive force transmitting, outside of the Middle longitudinal axis of the rotating member cable reversed is set after it leaves the control unit takes a curved course.

Derartige Bediengeräte, bei denen ein zur Drehachse des Knopfes achsparalleler Austritt des Zuges erfolgt, wie dies z.B. durch die FR-OS 22 84 924 bekannt ist, dienen bei heutigen Kraftwagen beispielsweise zum Betätigen von Heizungsklappen und sind an der Armaturentafel befestigt. Da der dem Bediengerät nachgeschaltete Bereich mit einer Vielzahl von Einbauteilen und elektrischen Leitungen ange­ füllt ist, bereitet die Verlegung des das Kabel auf­ nehmenden Zuges vielfach Schwierigkeiten, wobei wegen der erforderlichen kleinen Biegeradien die Bedienkräfte an­ steigen und sogar die Gefahr besteht, daß ein Abknicken der Kabelhülle auftritt.Such control devices, in which one to the axis of rotation of the Button axially parallel exit of the train is done as this e.g. known from FR-OS 22 84 924, serve in today's motor vehicles, for example, for actuating Heater flaps and are attached to the dashboard. Since the area downstream of the control unit with a Variety of built-in parts and electrical cables is filled, prepares the laying of the cable taking train often difficulties, whereby because of required small bending radii to the operating staff rise and there is even a risk of kinking the cable sheath occurs.

Es ist Aufgabe der Erfindung, das Bediengerät mit geringem Aufwand so umzugestalten, daß man bei gleichbleibenden Einbauverhältnissen zu größeren Biegeradien gelangt, so daß bei leichter Verstellbarkeit eine hohe Betriebssicherheit gegeben ist. It is an object of the invention, the control device with little To redesign the effort so that one with the same Installation conditions to larger bending radii, so that high operational reliability with easy adjustability given is.  

Diese Aufgabe wird dadurch gelöst, daß das Kabel sich innerhalb des Bediengerätes etwa in Richtung seines nachfolgenden Krümmungsverlaufes geneigt zur Mittel­ längsachse des Drehgliedes erstreckt, wobei neben den angestrebten größeren Biegeradien auch gleichzeitig ein kleinerer Biegewinkel in Erscheinung tritt.This object is achieved in that the cable itself within the control unit approximately in the direction of his subsequent curvature inclined to the middle extends along the axis of the rotary member, wherein in addition to the desired larger bending radii at the same time a smaller bending angle appears.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.An embodiment of the invention is as follows explained in more detail with reference to the drawing.

Ein vereinfacht dargestelltes Bediengerät 1, das von einer angedeuteten Armaturentafel 2 aufgenommen wird, ist mit einem Drehglied 3 in Form eines Drehknopfes versehen, der verdrehsicher mit einem einen kegelstumpfförmigen Rotations­ mantel aufweisenden Steuerteil 4 verbunden ist. An diesem ist eine in sich geschlossene Steuerkurve 5 angeformt, in die ein zu jedem abgehenden Zug 6 gehörendes und das eine Ende eines zug- und drucksteifen Kabels 7 auf­ nehmendes Gleitstück 8 eintaucht.A simplified operating device 1 , which is received by an indicated dashboard 2 , is provided with a rotary member 3 in the form of a rotary knob, which is connected to a control element 4 having a truncated cone-shaped rotation jacket. A self-contained control cam 5 is formed on this, into which a train 6 belonging to each outgoing train and the one end of a cable 7 which is resistant to tension and compression is immersed in the slider 8 .

Wird das Drehglied 3 um seine Mittellängsachse 9 verdreht, so bewegt sich das Gleitstück 8 und mit ihm das Kabel 7 schräg nach oben und außen, wobei sich jeweils an den geneigt zur Mittellängsachse 9 austretenden geraden Ab­ schnitt des Zuges 6 ein nicht dargestellter, in die gleiche Richtung weisender gekrümmter Abschnitt an­ schließt.If the rotary member 3 is rotated about its central longitudinal axis 9 , the slider 8 and with it the cable 7 moves obliquely upwards and outwards, with each section of the train 6 exiting at an incline to the central longitudinal axis 9 straight, not shown, into which the same direction pointing curved section closes.

Die kegelstumpfförmige Bauweise erbringt eine Vergrößerung des Hubes im Vergleich zu einem zylindrischen Rotations­ mantel, so daß ein vorgegebener, gleichbleibender Hub eine vorteilhafte Verkürzung der Baulänge ermöglicht. The frustoconical construction increases the size of the stroke compared to a cylindrical rotation coat, so that a predetermined, constant stroke one enables advantageous shortening of the overall length.  

Durch den Schräglauf des Gleitstückes 8 stellt sich, be­ zogen auf den Verstellweg, eine Veränderung des wirksamen Hebelarmes ein. Dadurch ist mit dem zunehmenden Einziehen der Kabel 7 eine Verkleinerung des bedienseitigen Hebel­ armes verbunden, so daß bei gleichbleibendem Bedienmoment fortlaufend größere Kräfte auf den Zug 6 aufgebracht werden können.By the skew of the slider 8 is, be related to the adjustment, a change in the effective lever arm. Characterized the increasing retraction of the cable 7 is a reduction in the operating lever arm, so that larger forces can be continuously applied to the train 6 with the same operating torque.

Dies läßt sich vorteilhaft dazu nutzen, die mit dem zu­ nehmenden Schließen der luftbeaufschlagten, zu verstellenden Klappen ansteigenden Staudruckkräfte und die erforderlichen Schließkräfte beim Anpressen der Klappendichtungen ohne spürbaren Einfluß auf die Bedienkräfte zu egalisieren.This can be used to advantage with the taking closing of the air-loaded, to be adjusted Flaps increasing dynamic pressure forces and the required Closing forces when pressing the flap seals without equalize noticeable influence on the operating personnel.
