Description
Die Erfindung bezieht sich auf einen Drehschalter mit einem manuell um eine Schwenkachse schwenkbar gelagerten Drehknopf, der aus seiner mittleren Ruhestellung in eine rechte und eine linke Schaltstellung schwenkbar ist und einen Schaltanschlag aufweist, durch den in der rechten und in der linken Schaltstellung jeweils ein Schalter betätigbar ist, sowie mit einer Rückstelleinrichtung, durch die der Drehknopf selbsttätig aus einer von seiner Ruhestellung abweichenden Schwenkstellung mittels Federkraft in seine Ruhestellung schwenkbar und in der Ruhestellung fixierbar ist.The invention relates to a rotary switch with a manually pivotally mounted about a pivot axis rotary knob, which is pivotable from its central rest position into a right and a left switch position and has a shift stop, by the switch in the right and in the left switch position operable is, as well as with a restoring device by which the knob is automatically from a position deviating from its rest position pivoting position by spring force in its rest position and fixed in the rest position.
Ein derartiger bekannter Drehschalter weist einen durch den Drehknopf aus einer mittleren Ruhestellung in eine rechte und eine linke Schaltstellung schwenkbaren Schalterzapfen mit einer radial durchgehenden Ausnehmung auf. An beiden Mündungsöffnungen der Ausnehmung ragt jeweils ein Stößel mit seinem einen Ende heraus, wobei die beiden Stößel mit ihren in der Ausnehmung befindlichen Bereich verschiebbar in der Ausnehmung geführt sind und durch eine zwischen den beiden Stößeln mit Vorspannung in der Ausnehmung angeordneten Druckfeder nach außen hin beaufschlagt sind. Beide Stößel ragen mit ihren nach außen gerichteten Enden jeweils in das Innere einer etwa V-förmigen Ausnehmung, deren inneren Spitzen koaxial zur Ausnehmung einander gegenüber liegen und deren seitliche Flanken rampenartig sich dem Schalterzapfen annähern.Such a known rotary switch has a pivotable by the knob from a central rest position into a right and a left switch position switch pin with a radially continuous recess. At both mouth openings of the recess each projecting a plunger with its one end, wherein the two plungers are guided with their located in the recess region slidably in the recess and acted upon by a between the two plungers with bias in the recess arranged compression spring to the outside are. Both plungers protrude with their outwardly directed ends in each case into the interior of an approximately V-shaped recess, the inner points coaxial with the recess face each other and the lateral edges of which approach ramps to the switch pin.
Befinden sich die Stößel mit ihren nach außen ragenden Enden in den inneren Spitzen der V-förmigen Ausnehmungen, so hat der Drehschalter seine mittlere Ruhestellung eingenommen. Durch manuelles Verdrehen in oder gegen den Uhrzeigersinn gleiten die nach außen ragenden Enden der Stößel an den seitlichen Flanken der V-förmigen Ausnehmungen entlang, bis sie an deren Enden an Anschlägen zur Anlage gelangen. Da sich diese Flanken dem Schalterzapfen annähern, wird bei dieser Schwenkbewegung die Druckfeder zwischen den Stößeln mehr und mehr gespannt. Bei Freigeben des Drehknopfs gleiten die Stößel unter der Kraftbeaufschlagung der Druckfeder an den rampenartigen Flanken der V-förmigen Ausnehmungen entlang, bis sie die inneren Spitzen der V-förmigen Ausnehmungen erreicht haben. Dadurch wird der Drehknopf wieder in seine Ruhestellung verschwenkt.Are the plunger with its outwardly projecting ends in the inner peaks of the V-shaped recesses, so the rotary switch has taken its mean rest position. By manually turning clockwise or counterclockwise, the outwardly projecting ends of the plungers slide along the lateral flanks of the V-shaped recesses until they abut stops at the ends thereof. Since these flanks approach the switch pin, the compression spring between the plungers is stretched more and more in this pivotal movement. Upon release of the knob, the plungers slide under the application of force to the compression spring along the ramped flanks of the V-shaped recesses until they reach the inner peaks of the V-shaped recesses. As a result, the knob is pivoted back to its rest position.
Aufgrund der Herstellungstoleranzen der Ausnehmung im Schalterzapfen, der Herstellungstoleranzen der beiden Stößel und der toleranzbedingten Abweichungen der inneren Spitzen der V-förmigen Ausnehmungen von der Längsachse der Ausnehmung im Schalterzapfen ist nicht nur die Ruhestellung des Drehknopfs nur unzureichend genau definiert, sondern es besteht auch ein erhebliches Spiel, um das der Drehknopf mit dem Schalterzapfen in deren Ruhestellung bewegbar ist.Due to the manufacturing tolerances of the recess in the switch pin, the manufacturing tolerances of the two plungers and the tolerance-related deviations of the inner peaks of the V-shaped recesses of the longitudinal axis of the recess in the switch pin not only the rest position of the knob is insufficiently well defined, but there is also a considerable Game by which the knob is movable with the switch pin in its rest position.
Das Dokument
Aufgabe der Erfindung ist es daher, einen Drehschalter der eingangs genannten Art zu schaffen, bei dem der Drehknopf zumindest weitestgehend spielfrei in seiner genau definierten Ruhestellung gehalten wird.The object of the invention is therefore to provide a rotary switch of the type mentioned, in which the knob is at least largely kept free of play in its well-defined rest position.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Drehknopf zwei Rückstellanschläge besitzt, die in einem Abstand voneinander und jeweils in einem radialen Abstand zur Schwenkachse an dem Drehknopf angeordnet und mit dem Drehknopf um die Schwenkachse schwenkbar sind und daß ein radial zur Schwenkachse verschiebbar geführter Schieber von einer Federkraft mit seiner einen Stirnseite zur Anlage an den Rückstellanschlägen beaufschlagt ist.This object is achieved in that the knob has two return stops, which are arranged at a distance from each other and each at a radial distance to the pivot axis on the knob and pivotable about the pivot axis with the knob and that a radially slidably guided to the pivot axis slider of a spring force is acted upon with its one end face to rest on the return stops.
Dadurch, daß der über eine große Führungslänge weitgehend spielfrei führbare Schieber als einziges verschiebbares Bauteil mit seiner Stirnseite direkt die Rückstellanschläge am Drehknopf beaufschlagt, ist bei Anlage beider Rückstellanschläge an der Stirnseite des Schiebers die Ruhestellung des Drehknopfs genau definiert. Liegt nur ein Rückstellanschlag an der Stirnseite des Schiebers an, wirkt unter der Federkraft damit ein Drehmoment auf den Drehknopf und verdreht diesen, bis auch der zweite Rückstellanschlag an der Stirnseite des Schiebers anliegt.Due to the fact that the slide, which is largely free of play over a large guide length, acts as the only displaceable component with its front side directly on the return stops on the rotary knob, the rest position of the rotary knob is precisely defined when the two return stops abut against each other at the end of the slide. If there is only one return stop on the end face of the slider, a torque acts on the rotary knob under the spring force and twists it until the second return stop abuts against the end face of the slider.
Eine Leichtgängigkeit der Rückstellung des Drehknopfs kann durch eine Gleitbeschichtung an der Stirnseite des Schiebers oder an den Rückstell-anschlägen erfolgen.A smooth running of the return of the knob can be done by a sliding coating on the front side of the slider or on the return strokes.
Sind die Anlageflächen an der Stirnseite des Schiebers, an denen die Rückstellanschläge in Anlage sind, unter einem Winkel rampenartig gegenüber der Führungsrichtung des Schiebers geneigt, so wird der Reibwiderstand der Rückstellanschläge an den Anlageflächen der Stirnseite des Schiebers reduziert und die Rückstellung des Drehknopfs in seine Ruhestellung erfolgt leichtgängig. Eine Zentrierung der Rückstellanschläge gegenüber dem Schieber in der Ruhestellung des Drehschalters erfolgt auf einfache Weise dadurch, daß die Anlageflächen symmetrisch zueinander und zur Führungsrichtung geneigt sind, wobei vorzugsweise die Anlageflächen zu den Randbereichen des Schiebers sich von der Schwenkachse entfernend geneigt sind.If the abutment surfaces on the end face of the slide on which the restoring stops are in contact inclined at an angle relative to the guide direction of the slide, the frictional resistance of the restoring stops on the contact surfaces of the end face the slider is reduced and the return of the knob to its rest position is smooth. A centering of the return stops relative to the slider in the rest position of the rotary switch is effected in a simple manner in that the contact surfaces are symmetrical to each other and inclined to the guide direction, wherein preferably the contact surfaces are inclined to the edge regions of the slider away from the pivot axis.
Zu einem leichgängigen Gleiten der Rückstellanschläge auf ihren Anlageflächen des Schiebers führt es, wenn die Anlageflächen um einen Winkel zwischen etwa 45° und 75° zur Führungsrichtung des Schiebers geneigt sind.It leads to a smooth sliding of the return stops on their contact surfaces of the slide, when the contact surfaces are inclined by an angle between about 45 ° and 75 ° to the guide direction of the slider.
Sind die Rückstellanschläge in einem Winkelabstand von etwa zwischen 100° und 220°, vorzugsweise von etwa 130° am Drehknopf angeordnet, so wird bei relativ geringem Drehwinkel ein relativ großer Verschiebeweg des Schiebers erreicht, was zu einem deutlichen stetigen Anstieg des erforderlichen Drehmoments beim Verdrehen des Drehknopfs aus seiner Ruhestellung führt. Ein unbeabsichtigtes Schalten eines der Schalter wird damit erheblich erschwert.If the return stops are arranged at an angular distance of approximately between 100 ° and 220 °, preferably of approximately 130 ° on the rotary knob, then a relatively large displacement of the slider is achieved at a relatively low angle of rotation, resulting in a significant steady increase in the required torque during rotation of the slider Turn knob from its rest position leads. Inadvertent switching of one of the switches is thus considerably more difficult.
Sind an einer Schalterplatte zwei parallel zueinander sich erstreckende Führungen angeordnet, zwischen den der Schieber verschiebbar geführt ist, so befindet sich die Führung des Schiebers an einem feststehenden Bauteil, wodurch die Möglichkeit toleranzbedingter Spiele erheblich reduziert ist.Are two parallel mutually extending guides arranged on a switch plate, between which the slide is guided displaceably, so is the leadership of the slide on a fixed component, whereby the possibility of tolerance-related games is significantly reduced.
Zur Erzeugung der Federkraft kann in einfacher und bauteilarmer Weise der Schieber unter Vorspannung von einer Druckfeder zur Anlage an den Rückstellanschlägen beaufschlagt sein, die an einem Abstützanschlag der Schalterplatte abgestützt ist.To produce the spring force, the slide can be biased by a compression spring to rest against the return stops in a simple and low-component manner, which is supported on a support stop of the switch plate.
Dabei kann ebenfalls bauraumsparend die Druckfeder mit einem Teil ihrer Längserstreckung in einer sich in Führungsrichtung des Schiebers im Schieber erstreckende Kammer geführt sein.It can also be space-saving, the compression spring with a part of its longitudinal extension in a guided in the guide direction of the slide in the slide chamber.
Ebenfalls bauraum- und bauteilsparend ist es, wenn die Schalterplatte eine zur Schwenkachse koaxiale Führungsbohrung aufweist, in der ein die Rückstellanschläge tragender Schalterzapfen des Drehknopfs drehbar geführt ist.It is also space-saving and component-saving, when the switch plate has a coaxial to the pivot axis guide bore in which a reset stops bearing switch pin of the knob is rotatably guided.
In einfacher Weise kann der aus der Führungsbohrung herausragende Bereich des Schalterzapfens rohrabschnittsartig ausgebildet sein, wobei die radial umlaufend gerichteten Enden des Rohrabschnitts die Rückstellanschläge bilden.In a simple way, the projecting from the guide bore portion of the switch pin may be formed like a pipe section, wherein the radially circumferentially directed ends of the pipe section forming the return stops.
Weist die Schalterplatte einen die Führungsbohrung mit ihrer zylindrischen Innenwand fortsetzenden rohrabschnittsartigen Ansatz auf, an dessen zylindrischer Innenwand der die Rückstellanschläge aufweisende Rohrabschnitt des Schalterzapfens drehbar geführt ist, wobei die radial umlaufende Erstreckung des rohrabschnittsartigen Ansatzes geringer ist als die radial umlaufende Erstreckung des Rohrabschnitts des Schalterzapfens, so wird ohne zusätzliche Bauteile eine große Führungslänge für die Drehlagerung des Schalterzapfens erreicht.Does the switch plate on the guide bore with its cylindrical inner wall continuing tubular section-like approach, is rotatably guided on the cylindrical inner wall of the Rückstellanschläge having pipe section of the switch pin, wherein the radially encircling extent of the pipe section-like approach is less than the radially encircling extent of the pipe section of the switch pin, so is achieved without additional components a large guide length for the pivotal mounting of the switch pin.
Ohne das Erfordernis separater Bauteile wird eine einfache Rastmontage des mit den Rückstellanschlägen, dem Schalterzapfen und dem Drehknopf einteilig ausgebildeten Bauteils erreicht, wenn an dem axial freien Ende des Rohrabschnitts des Schalterzapfens eine radial federnde Raste ausgebildet ist, die das axial freie Ende des rohrartigen Ansatzes umgreift und daß an dem durch die Führungsbohrung zur anderen Seite der Schalterplatte ragenden Ende der Drehknopf sich axial an der Schalterplatte abstützend angeordnet ist.Without the requirement of separate components, a simple latching assembly of the restoring stops, the switch pin and the knob integrally formed component is achieved if at the axially free end of the pipe section of the switch pin a radially resilient catch is formed, which surrounds the axially free end of the tubular extension and that at the projecting through the guide bore to the other side of the switch plate end of the knob is arranged axially supported on the switch plate.
Zur Betätigung der Schalter kann an dem Drehknopf ein parallel zur Schwenkachse sich erstreckender Schaltanschlag angeordnet sein, der einen ringabschnittsartigen Schlitz in der Schalterplatte durchragt und durch den die auf der dem Drehknopf abgewandten Seite der Schalterplatte an den beiden Enden des Schlitzes angeordneten Schalter betätigbar sind.To actuate the switch, a parallel to the pivot axis extending shift stop can be arranged on the knob, which projects through a ring-section-like slot in the switch plate and through which on the side facing away from the knob side of the switch plate arranged at the two ends of the slot switch can be actuated.

An den beiden Enden des ringabschnittsartigen Schlitzes 8 ist jeweils ein als Tastschalter ausgebildeter Schalter 9 und 9' an der Schalterplatte 7 angeordnet, deren Schaltelemente 10 und 10' von dem Schaltanschlag 5 beaufschlagbar sind.In the installed state, in which the
Auf der dem Drehknopf 1 abgewandten Seite wird die Führungsbohrung 6 durch einen rohrabschnittsartigen Ansatz 11 fortgesetzt, wobei die radial umlaufende Erstreckung des rohrabschnittartigen Ansatzes 11 geringer ist als die radial umlaufende Erstreckung des Rohrabschnitts 14 des Schalterzapfens 2.On the side facing away from the
An dem axial freien Ende des Rohrabschnitts 14 des Schalterzapfens 2 ist eine radial nach außen federnde Raste 12 ausgebildet, die mit ihrer Rastnase 13 das axial freie Ende des rohrabschnittsartigen Ansatzes 11 umgreift. Bei Einführen des Schalterzapfens 2 in die Führungsbohrung 6 bis zur Anlage des Drehknopfs 1 an der Schalterplatte 7, gelangt die Rastnase 13 in eine Position, in der sie das axial freie Ende des Ansatzes 11 umgreifend einrastet.At the axially free end of the
Zwischen zwei parallel zueinander sich erstreckenden, an der dem Drehknopf 1 abgewandten Seite der Schalterplatte 7 angeordneten Führungen 15 ist ein Schieber 16 mit daran ausgebildeten Führungsnuten 17 radial zur Schwenkachse 4 geführt.
