The lever (13) is arranged on the push-button (4) to rotate about a fixed bearing (14) in the housing (1) on one side and about a bearing (15) articulated about the fixed housing bearing (14) on the other.

Description

Die Erfindung bezieht sich auf einen elektrischen Drucktastenschalter, insbesondere für Kraftfahrzeuge, mit einer im Schaltergehäuse federbelastet geführten Drucktaste, die mittels zweier Hebel, die einerseits an einem Lager im Gehäuse und andererseits an einem um das vorgenannte Lager schwenkenden Lager in der Drucktaste angeordnet sind, gelenkig mit dem Gehäuse verbunden ist, wobei die Hebel jeweils einen Ansatz mit einem Mitnahmelager aufweisen, und die beiden Mitnahmelager durch eine Stange verbunden sind.The invention relates to an electrical pushbutton switch, in particular for motor vehicles, with a pushbutton which is guided in the switch housing in a spring-loaded manner and which is articulated by means of two levers which are arranged on the one hand on a bearing in the housing and on the other hand on a bearing pivoting about the aforementioned bearing in the pushbutton is connected to the housing, the levers each having a shoulder with a driving bearing, and the two driving bearings are connected by a rod.

Ein derartiger Drucktastenschalter ist aus der FR-A-2 175 105 bekannt. Dieser Drucktastenschalter weist ein Gehäuse und eine Drucktaste auf, wobei die Drucktaste mittels zweier Hebel, die einerseits an einem ortsfesten Lager im Gehäuse und andererseits an einem ortsfesten, um das gehäusefeste Lager schwenkenden Lager an der Drucktaste angeordnet sind, gelenkig mit dem Gehäuse verbunden ist. Die Hebel bestehen aus dreieckigen Teilen, deren eine Spitze durch das ortsfeste Lager im Gehäuse, die zweite Spitze durch das ortsfeste Lager an der Drucktaste und die dritte Spitze durch ein Mitnahmelager eingenommen werden, wobei beide Mitnahmelager durch eine Stange verbunden sind. Der Teil des Dreiecks, der das ortsfeste Lager im Gehäuse mit dem ortsfesten Lager an der Drucktaste verbindet, kann als eigentlicher Hebel betrachtet werden, wobei der übrige Teil als einstückig angeformter Ansatz betrachtet werden kann. Die Drucktaste wird nach ihrer Betätigung durch eine in einem Schalter vorhandene Feder in ihre Ausgangsstellung zurückgeführt.Such a push button switch is known from FR-A-2 175 105. This pushbutton switch has a housing and a pushbutton, the pushbutton being articulated to the housing by means of two levers which are arranged on the one hand on a fixed bearing in the housing and on the other hand on a fixed bearing pivoting about the housing-fixed bearing on the pushbutton. The levers consist of triangular parts, one tip of which is taken up by the fixed bearing in the housing, the second tip is taken up by the fixed bearing on the push button and the third tip is taken up by a driving bearing, both driving bearings by one Rod are connected. The part of the triangle that connects the fixed bearing in the housing with the fixed bearing on the push button can be regarded as the actual lever, the remaining part can be regarded as an integrally molded attachment. After actuation, the pushbutton is returned to its starting position by a spring present in a switch.

Der Erfindung liegt die Aufgabe zugrunde, einen elektrischen Drucktastenschalter der eingangs genannten Art zu schaffen, bei dem bei einseitig betätigter Drucktaste sich diese ohne Schrägstellung und ohne Verklemmung gleichmäßig bei gleichzeitig großem Spiel zwischen Drucktaste und Gehäuse sowie gegebenem Toleranzausgleich bewegen läßt.The invention has for its object to provide an electrical push button switch of the type mentioned, in which with one-sided push button this can be moved without inclination and without jamming evenly with a large amount of play between the push button and the housing and given tolerance compensation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß

  • das gehäuseseitige Lager für den einen Hebel ortsfest und das gehäuseseitige Lager für den anderen Hebel als Langloch im Gehäuse ausgebildet ist, und
  • an dem Ansatz des im Langloch gehaltenen Hebels ein entgegen der Drucktaste wirkendes Federelement eingreift.
This object is achieved in that
  • the housing-side bearing for one lever is stationary and the housing-side bearing for the other lever is designed as an elongated hole in the housing, and
  • a spring element acting against the push button engages at the shoulder of the lever held in the elongated hole.

Durch diese Maßnahmen wird neben der zuverlässigen Betätigung des Drucktastenschalters ein Toleranzausgleich erreicht, da die über den Ansatz eines der Hebel und die Stange eingeleitete Kraft des Federelementes, die gegen die Wirkrichtung der Drucktaste einfließt, ein Festlegen der Drucktaste gegen das in Richtung der Drucktaste wirkende Federelement bewirkt.Through these measures, in addition to the reliable actuation of the push button switch, tolerance compensation is achieved, since the force of the spring element introduced via the attachment of one of the levers and the rod, which flows in against the direction of action of the push button, defines the push button against the spring element acting in the direction of the push button causes.

In Ausgestaltung der Erfindung sind vier, das Gehäuse mit der Drucktaste gelenkig verbindende Hebel vorgesehen, wobei je zwei Hebel koaxial ausgerichtet und über einen Träger verbunden sind. Hierdurch wird bei der Anordnung der Hebel unter den Ecken einer großflächigen Drucktaste ein reibungsfreies Niederdrücken der Drucktaste erreicht, wobei über die koaxiale Verbindung von je zwei Hebeln eine Zwangsmitnahme der beiden koaxialen Hebel erfolgt. Zweckmäßigerweise sind die vier Hebel zwischen dem Gehäuse und der Drucktaste über die in ihren Mitnahmelagern befestigten Stangen mit einem Steg zwischen den Stangen verbunden. Somit überträgt sich der Verstellweg von Stange zu Stange direkt über den Steg. Bevorzugt ist jeder Hebel über eine Klipsverbindung oder einstückig über ein Filmscharnier mit der zugehörigen Stange verbunden.In an embodiment of the invention, four levers are provided, which connect the housing to the pushbutton in an articulated manner, two levers each being aligned coaxially and connected via a carrier. In this way, when the levers are arranged under the corners of a large-area pushbutton, the pushbutton is depressed without friction, with the coaxial connection of two levers forcing the two coaxial levers. The four levers between the housing and the pushbutton are expediently connected to a web between the rods via the rods fastened in their carrier bearings. This means that the adjustment path is transferred from rod to rod directly via the web. Each lever is preferably connected to the associated rod via a clip connection or in one piece via a film hinge.

Zur Begrenzung des weitesten Weges der Drucktaste aus dem Gehäuse heraus ist nach einer weiteren Ausgestaltung am Gehäuse ein Anschlag vorgesehen, an dem der Ansatz eines der Hebel unter der Wirkung des die Drucktaste beaufschlagenden Federelementes zur Anlage kommt. Durch diese Festlegung der äußeren Schaltstellung der Drucktaste erhält man ein gleichmäßiges Anliegen des Ansatzes des Hebels am Anschlag, und ein leichtes Lösen des Ansatzes vom Anschlag ist bei Bedienung der Drucktaste gewährleistet.In order to limit the longest path of the push button out of the housing, a stop is provided on the housing according to a further embodiment, at which the attachment of one of the levers comes into contact under the action of the spring element acting on the push button. This definition of the outer switch position of the push button results in a uniform contact of the shoulder of the lever with the stop, and an easy detachment of the shoulder from the stop is ensured when the push button is operated.

Zweckmäßigerweise ist in dem Gehäuse eine Leiterplatte mit einem daran festgelegten Schaltelement angeordnet, dessen federbelasteter Schaltknopf die selbsttätige Rückstellung der Drucktaste bewirkt. Auf der Leiterplatte ist weiterhin bevorzugt ein Beleuchtungselement befestigt, dessen Glühlampe in die Öffnung eines Leuchtschirmes eintaucht. Durch den Einsatz einer Leiterplatte mit daran angeordneten Bauelementen ist es möglich, auf einfache Weise unterschiedliche Schaltbilder und Schaltfunktionen zu erreichen, wobei sich die Montageart nicht ändert.A circuit board with a switching element attached to it is expediently arranged in the housing, the spring-loaded switching button of which causes the pushbutton to be automatically reset. On the circuit board is also preferred attached a lighting element, the light bulb immersed in the opening of a fluorescent screen. By using a printed circuit board with components arranged thereon, it is possible to easily achieve different circuit diagrams and switching functions, the type of mounting not changing.

Um eine abgegrenzte Ausleuchtung der Drucktaste zu erhalten, ist nach einer Weiterbildung der Erfindung die Drucktaste als Zweifarbenspritzteil hergestellt, dessen Außenmantel luminiszent und dessen Innenmantel opak ist, wobei am Innenmantel Laschen für eine Klipsverbindung mit dem Leuchtschirm und Schenkel zur Aufnahme der schwenkenden Lager angeformt sind. Auf diese Weise hält das Material des Innenmantels die hohen Belastungen der Klipsverbindungen aus und das Material des Außenmantels liegt gleichmäßig über die gesamte Fläche der Drucktaste vor. Auch ein gewünschtes Symbol kann somit in die Drucktaste eingespritzt werden.In order to obtain a delimited illumination of the pushbutton, the pushbutton is produced as a two-color injection molded part, the outer casing of which is luminous and the inner casing of which is opaque, with tabs for a clip connection with the luminescent screen and legs for integrating the pivoting bearings being formed on the inner casing. In this way, the material of the inner jacket withstands the high loads on the clip connections and the material of the outer jacket is uniform over the entire surface of the push button. A desired symbol can also be injected into the push button.

Eine alternative Lösung der der Erfindung zugrundeliegenden Aufgabe zeichnet sich dadurch aus, daß in dem Gehäuse eine Führungsfläche angeordnet ist, an der sich die Stange unter der Wirkung eines Federelementes abstützt, wobei die Mitnahmelager in der Stange als Langlöcher ausgebildet und am Ansatz der Hebel entsprechende Zapfen angeformt sind, die in die Langlöcher eingreifen. Bevorzugt stützt sich hierbei das Federelement mit seinem einen Ende am Boden einer Grundbohrung in der Stange und mit seinem anderen Ende auf einer Kontaktbrücke ab, wobei Mitnahmeschultern der Kontaktbrücke in Öffnungen der Stange geführt sind, und die Kontaktbrücke mit Anschlußkontakten im Boden des Gehäuses zusammenwirkt. Hierdurch werden neben der zuverlässigen Betätigung des Drucktastenschalters sowie des Toleranzausgleichs große Ströme und Schaltleistungen mit dem Drucktastenschalter erreicht. Weiterhin erfüllt hierbei die Stange zwei Funktionen, nämlich die zwangsweise Mitnahme der Hebel und somit der Drucktaste und außerdem die Funktion eines Schaltgliedes, wobei die Stange die Kontaktbrücke führt, und über die Druckfeder unterhalb der Kontaktbrücke stets eine ausreichende Kontaktkraft vorhanden ist. Der Boden des Gehäuses kann unterschiedlich gestaltet werden, wodurch nach einem Austausch auch andere Schaltzustände erreicht werden. Zweckmäßigerweise ist am Boden des Gehäuses ein Beleuchtungselement befestigt, dessen Glühlampe in die Öffnung eines Leuchtschirmes eintaucht.An alternative solution to the problem underlying the invention is characterized in that a guide surface is arranged in the housing, on which the rod is supported under the action of a spring element, the driving bearings in the rod being designed as elongated holes and corresponding pins at the base of the lever are formed, which engage in the elongated holes. In this case, the spring element is preferably supported with one end at the bottom of a basic bore in the rod and with its other end on a contact bridge, with drive shoulders of the contact bridge in Openings of the rod are guided, and the contact bridge interacts with connecting contacts in the bottom of the housing. As a result, in addition to the reliable actuation of the pushbutton switch and the tolerance compensation, large currents and switching capacities are achieved with the pushbutton switch. Furthermore, the rod fulfills two functions, namely the compulsory entrainment of the lever and thus the pushbutton and also the function of a switching element, the rod guiding the contact bridge, and a sufficient contact force is always present below the contact bridge via the compression spring. The bottom of the housing can be designed differently, which means that other switching states can also be achieved after replacement. A lighting element is expediently attached to the bottom of the housing, the incandescent lamp of which is immersed in the opening of a fluorescent screen.

The carriers 16 are designed as flat disks to save material. In order to make it easier to mount the levers 13 with the supports 16 in between in the housing 1, this connection is designed as a clip connection 17: a clip connection 18 enables the lever to be easily mounted on the pushbutton 4.

Einstückig am Hebel 13 ist ein Ansatz 19 angeformt, an dessen Ende 20 ein Mitnahmelager 21 vorhanden ist, das um das ortsfeste Lager 14 im Gehäuse 1 schwenkt. Das am Ansatz 19 des Hebels 13 befindliche Mitnahmelager 21 ist senkrecht zur Verbindungslinie 27 zwischen dem ortsfesten Lager 14 im Gehäuse 1 und dem schwenkbaren Lager 15 an der Drucktaste 4 angeordnet, wobei im Ausführungsbeispiel sie lotrecht auf der Achse des ortsfesten Lagers 14 im Gehäuse 1 steht.A projection 19 is integrally formed on the lever 13, at the end 20 of which there is a driving bearing 21 which pivots about the fixed bearing 14 in the housing 1. The drive bearing 21 located at the shoulder 19 of the lever 13 is arranged perpendicular to the connecting line 27 between the fixed bearing 14 in the housing 1 and the pivotable bearing 15 on the pushbutton 4, in the exemplary embodiment it is perpendicular to the axis of the fixed bearing 14 in the housing 1 .

Eine weitere Zwangsmitnahme erfolgt dadurch, daß mindestens zwei Hebel 13 mit gleicher Schwenkausrichtung des Ansatzes 19 in Richtung der Schwenkung des Mitnahmelagers 21 durch eine Stange 22 mittels Klipsverbindungen 23 verbunden sind. Am Träger 16 ist ein Trägeransatz 24 einstückig angeformt, der die Stabilität der Ansätze 19 gewährleistet.A further forced driving takes place in that at least two levers 13 with the same pivoting orientation of the projection 19 in the direction of the pivoting of the driving bearing 21 are connected by a rod 22 by means of clip connections 23. A carrier extension 24 is integrally formed on the carrier 16, which ensures the stability of the extensions 19.

Beim Bedienen der Drucktaste 4 schwenkt der Hebel 13 um das ortsfeste Lager 14 im Gehäuse 1 und das schwenkende Lager 15 an der Drucktaste 4 sowie das Mitnahmelager 21 an dem Ansatz 19 im Uhrzeigersinn, beim Loslassen der Drucktaste 4 schwenkt der Hebel 4 mit seinen angeformten Lagern 15 und 21 entgegen dem Uhrzeigersinn. Verbessert wird die Zwangsmitnahme noch dadurch, daß die vier Hebel 13 zwischen dem Gehäuse 1 und der Drucktaste 4 über die in ihren Mitnahmelagern 21 befestigten Stangen 22 mit einem Steg 25 zwischen den Stangen 22 verbunden sind. Die Mitnahme erfolgt dadurch direkt und wird nicht noch durch Fertigungstoleranzen beeinflußt.When operating the pushbutton 4, the lever 13 pivots around the fixed bearing 14 in the housing 1 and the pivoting bearing 15 on the pushbutton 4 and the driving bearing 21 on the shoulder 19 in a clockwise direction, when the pushbutton 4 is released, the lever 4 pivots with its molded bearings 15 and 21 counterclockwise. The forced driving is further improved in that the four levers 13 between the housing 1 and the push button 4 are connected to a web 25 between the rods 22 via the rods 22 fastened in their driving bearings 21. This means that they are taken along directly and are not influenced by manufacturing tolerances.

Im unbetätigten Zustand der Drucktaste 4, die unter Wirkung eines Federelementes 28 nach außen gedrückt wird, liegt der Ansatz 19 an einem Anschlag 26 an, womit der Betätigungshub nach oben begrenzt wird. Beim Bedienen der Drucktaste 4 schwenkt der Ansatz 19 vom Anschlag 26 weg. Die Drucktaste 4 wird dabei gegen die Wirkung des Federelementes 28, das sich zum einen in Schaltelement 29 befindet oder alternativ dazu zwischen der Leiterplatte 30 und einem Aufnahmemittel 31 an der Drucktaste 4 eingespannt ist.In the unactuated state of the pushbutton 4, which is pressed outwards under the action of a spring element 28, the shoulder 19 bears against a stop 26, which limits the actuation stroke upwards. When operating the pushbutton 4, the shoulder 19 pivots away from the stop 26. The pushbutton 4 is pressed against the action of the spring element 28, which is located in the switching element 29 or, alternatively, between the circuit board 30 and a receiving means 31 on the pushbutton 4.

In der Figur 7 ist eine alternative Ausführung dargestellt. Darin ist bei durch Stangen 22 verbundenen Hebeln 13 ein Hebel 13 in einem ortsfesten Lager 14 im Gehäuse 1 gehaltert und die Lager 32 für alle weiteren Hebel 33 durch je ein Langloch 34 im Gehäuse 1 gebildet. An dem Ansatz 19 des im Langloch 34 gehaltenen Hebels 33 greift eine Druckfeder 35 an, dessen Wirkrichtung entgegen der Drucktaste 4 einfließt. Für die Halterung der Druckfeder 35 ist am Trägeransatz 24 des Hebels 33 ein Zapfen 36 angeformt und im Gehäuse 1 ist eine Einbuchtung 37 eingeformt, dessen innerer Bereich als Schale 38 ausgebildet ist, in der die Druckfeder 35 liegt. Die Druckfeder 35 stützt sich also mit ihrem einen Ende an der Innenwand des Gehäuses 1 und mit ihrem anderen Ende auf dem Trägeransatz 24 des Hebels 33 ab.An alternative embodiment is shown in FIG. In this case, in the case of levers 13 connected by rods 22, a lever 13 is held in a fixed bearing 14 in the housing 1 and the bearings 32 for all further levers 33 are each formed by an elongated hole 34 in the housing 1. A pressure spring 35 acts on the extension 19 of the lever 33 held in the slot 34, the direction of action of which flows in counter to the push button 4. To hold the compression spring 35, a pin 36 is formed on the support shoulder 24 of the lever 33 and an indentation 37 is formed in the housing 1, the inner region of which is designed as a shell 38 in which the compression spring 35 lies. The compression spring 35 is thus supported at one end on the inner wall of the housing 1 and at the other end on the support shoulder 24 of the lever 33.

Im Gehäuse 1 ist eine Leiterplatte 30 eingespannt mit einem darauf befindlichen Schaltelement 29. Im Schaltelement 29 ist ein Federelement 28 vorhanden, das den Schaltknopf 39 des Schaltelementes 29 selbsttätig in die äußere Schaltposition bringt. Auf der Oberseite des Schaltknopfes 39 des Schaltelementes 29 liegt ein Druckstößel 40 der Drucktaste 4 an über den die Drucktaste 4 in die äußere Schaltstellung gebracht wird. Auf der Leiterplatte 30 befinden sich die nicht dargestellten Leiterbahnen zur Realisierung der Strompfade zwischen den Anschlußsteckern 11, dem Schaltelement 29 und dem Beleuchtungselement 41.

Die Anschlußstecker 11 sind rechtwinklig abgebogen und das Gehäuse 1 hat im Bereich der Abbiegung eine Freilassung 43. Im Beleuchtungselement 41 befindet sich eine Glühlampe 60, die durch die Öffnung 45 in das Innere eines Leuchtschirmes 44 eingetaucht ist.A printed circuit board 30 is clamped in the housing 1 with a switching element 29 located thereon. In the switching element 29 there is a spring element 28 which switches the button 39 of the switching element 29 automatically brings into the outer switching position. On the upper side of the button 39 of the switching element 29 is a push rod 40 of the push button 4 via which the push button 4 is brought into the outer switching position. On the circuit board 30 are the conductor tracks, not shown, for realizing the current paths between the connector plugs 11, the switching element 29 and the lighting element 41. The connector plugs 11 and the switching element 29 are soldered, the lighting element 41 is detachably fastened. On the upper side of the printed circuit board 30 there is a guide stub 42 which fixes the spring element 28 in its position. The connector plugs 11 are bent at right angles and the housing 1 has a release 43 in the area of the bend. In the lighting element 41 there is a light bulb 60 which is immersed through the opening 45 in the interior of a fluorescent screen 44.

In diesem Ausführungsbeispiel weist das Gehäuse 1 eine Führungsfläche 46 auf, an der sich die Stange 22 unter Wirkung einer Druckfeder 47 abstützt. An dieser Führungsfläche 46 bewegt sich die Stange 22 stets linear entlang. Um dies zu ermöglichen, sind die Mitnahmelager 48 der Stange 22 als Langlöcher 49 ausgebildet und am Ansatz 19 des Hebels 13 sind entsprechende Zapfen 51 angeformt, die in die Langlöcher 49 der Stange 22 eingreifen. Die Stange 22 ist hierbei in ihrem Querschnitt wesentlich breiter und übernimmt die Funktion eines Schaltgliedes,in dem die Druckfeder 47 sich mit einem Ende 50 am Boden 52 einer Grundbohrung 53 in der Stange 22 und mit ihrem anderen Ende 54 sich auf einer Kontaktbrücke 55 abstützt, wobei die Mitnahmeschulter 56 der Kontaktbrücke 55 in Öffnungen 57 der Stange 22 geführt sind und die Kontaktbrücke 55 mit Anschlußkontakten 58, welche zu den Anschlußsteckern 11 führen, im Boden 59 des Gehäuses 1 zusammenwirken. Der Boden 59 ist am Gehäuse 1 durch eine nicht dargestellte Klipsverbindung befestigt. Am Boden 59 des Gehäuses 1 ist ein Beleuchtungselement 41 befestigt, dessen Glühlampe 60 in die Öffnung 45 eines Leuchtschirmes 44 eintaucht.An alternative embodiment of the rod 22 is shown in FIG. 8. In this exemplary embodiment, the housing 1 has a guide surface 46 on which the rod 22 is supported under the action of a compression spring 47. The rod 22 always moves linearly along this guide surface 46. To make this possible, the driving bearings 48 of the rod 22 are designed as elongated holes 49 and corresponding pins 51 are formed on the extension 19 of the lever 13, which engage in the elongated holes 49 of the rod 22. The rod 22 is in this case substantially wider in cross section and takes over the function of a switching element in which the compression spring 47 is supported with one end 50 on the bottom 52 of a basic bore 53 in the rod 22 and with its other end 54 on a contact bridge 55, the drive shoulder 56 of the contact bridge 55 are guided in openings 57 of the rod 22 and the contact bridge 55 with contacts 58, which lead to the connectors 11, cooperate in the bottom 59 of the housing 1.
