Description
Die Erfindung betrifft einen Drucktastenschalter für elektrische Nachrichtengeräte, insbesondere für Rundfunk- und Fernsehgeräte, bestehend aus einem Tastenknopf, einem Schaltelement, z. B. einem Membran-Schaltelement mit Mehrfachkontaktstellen, wobei der Tastenknopf eine Rechteckform mit mehreren Bedienfelder aufweist und mit dem Schaltelement in einem Geräte-Gehäuseteil eingesetzt ist, wobei ferner mehrere darunterliegende elektrische Kontaktstellen des Schaltelements durch Verschwenken des im Bereich der Bedienfelder um Lagerstellen taumelbar angeordneten Tastenknopfes betätigbar sind. Es sind verschiedenartig aufgebaute Drucktastenschalter bekannt, bei denen jedoch vorwiegend für jede Schaltfunktion eine eigene Taste vorhanden ist, die einen oder mehrere Kontakte eines Schaltelements gleichzeitig betätigt.The invention relates to a push button switch for electrical news devices, in particular for radio and television sets, consisting of a button, a switching element, for. B. a membrane switching element with multiple contact points, wherein the button has a rectangular shape with several control panels and is used with the switching element in a device housing part, wherein further underlying electrical contact points of the switching element by pivoting the key button arranged in the area of the control panels tumbling around bearings can be operated. Pushbutton switches of various designs are known, but in which there is predominantly a separate button for each switching function which actuates one or more contacts of a switching element simultaneously.
Auch sind Mehrfach-Drucktasten bekannt, die nur einen quadratischen Tastenknopf aufweisen, wobei der Tastenknopf über alle vier Seiten zur Betätigung eines Schaltkontaktes kippbar ist. Aus der amerikanischen Patentschrift US-A-3 399 287 ist ein Tastenschalter mit den Merkmalen des Oberbegriffs des Anspruchs 1 bekannt, bei dem ein rechteckiger Tastenknopf sechs Bedienfelder aufweist. Der Tastenknopf ist mittig auf einem Kontaktträger allseits taumelbar gelagert. Die Lagerstelle selbst besteht aus einer Lagerbuchse am Kontaktträgerteil und einem Lagerzapfen mit Druckfeder und Klemmscheibe am Tastenknopf.Multiple pushbuttons are also known which have only a square button, the button being tiltable over all four sides for actuating a switch contact. From the American patent specification US-A-3 399 287 a key switch with the features of the preamble of claim 1 is known, in which a rectangular key button has six control panels. The button is centered on a contact carrier so that it can wobble on all sides. The bearing point itself consists of a bearing bush on the contact carrier part and a bearing pin with compression spring and clamping disk on the button.
Ein derartiger Aufbau ist aufwendig und durch seine Mittenlagerung bei mehr als sechs, insbesondere acht oder neun Bedienfeldern ergeben sich unterschiedliche Betätigungskräfte an den einzelnen Bedienfeldern. Eine Ausführung eines mittig taumelbar gelagerten Drucktastenschalters ist ferner durch die französische Patentschrift FR-A-2 446 007 bekannt. Der Tastenschalter weist mehrere Bedienfelder und für jedes dieser Felder einen gleichen Betätigungsdruck auf, da die Form des Tastenknopfes als kreisrunde Scheibe ausgebildet ist.Such a structure is complex and due to its central bearing with more than six, in particular eight or nine control panels, different actuation forces result on the individual control panels. An embodiment of a push-button switch mounted in a wobble position is also known from the French patent FR-A-2 446 007. The key switch has several control panels and the same actuation pressure for each of these fields, since the shape of the key button is designed as a circular disk.
Die Aufgabe der Erfindung besteht nun darin, eine einfache Lagerung eines rechteckförmigen Tastenknopfes in einem Mehrfach-Drucktastenschalter zu finden, die es ermöglicht, daß mit nur einem Tastenknopf eine mehr als vierfache Schaltfunktion, insbesondere eine sechs- und mehrfache Schaltfunktion möglich ist.The object of the invention is to find a simple storage of a rectangular button in a multiple push button switch, which enables a more than four-fold switching function, in particular a six- and multiple switching function is possible with just one button.
Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of claim 1.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.Further advantageous embodiments of the invention result from the dependent claims.

In der Figur 1 ist ein Drucktastenschalter 1, der im wesentlichen aus einem Tastenknopf 2 und aus einem Schaltelement 3 besteht, gezeigt. Der dargestellte Tastenknopf weist beispielsweise sechs Bedienfelder 4 auf, von denen je eines im Eckbereich des Tastenknopfes und zwei im Mittenbereich der Längsseite angeordnet sind. Der Tastenknopf und das Schaltelement sind bekannterweise in einem Geräte-Gehäuseteil 5 eingesetzt. Der Tastenknopf 2 besteht aus einer Deckplatte 6, an die auf der Schaltelementseite im äußeren Schmalseitenbereich zwei gespreizte federnde Stützbeine 7 und gegenüber den Bedienfeldern 4 je eine federnde Schaltzunge 8 angeordnet sind. Die Stützbeine stützen sich auf ein mit dem Gerätegehäuseteil direkt verbundenen Trägerplatte 9 ab, oder die Trägerplatte ist Teil des Schaltelements 3. Das Schaltelement besteht nach Fig. 1 beispielsweise aus der Trägerplatte 9, einer Kontaktfolie 10 mit darunterliegender Leitermusterplatte 10' und einer Zwischenplatte 11. Zur Erzielung eines bestimmten Druckpunktes bei Betätigung des Tastenknopfes ist unter der Schaltzunge ein elastischer, domartiger Kontaktknopf 12 eingelegt, der wiederum als über Totpunkt-Druckknopfteil auf die Kontaktfolie zur Kontaktgabe drückt. Die Schaltzungen 8 wirken mit unterschiedlichen Federkräften auf die Kontaktstellen, um hierdurch ein getrenntes Betätigen der Kontaktstellen zwischen den Bedienfeldern im Eckbereich zu den im Mittenbereich der Längs- . seiten zu gewährleisten. Der Tastenknopf 2 mit Bedienfeldern 4, Stützbeinen 7 und Schaltzungen 8 ist in vorteilhafter Weise einstückig aus elastischem Kunststoff gefertigt.FIG. 1 shows a push button switch 1, which essentially consists of a
Die Figur 2 zeigt einen Drucktastenschalter 1 mit einem Tastenknopf 2, der nur drei Bediehfeider4 aufweist. In einen Tastenknopf dieser Art ist an der Stelle des fehlenden Bedienteils im Eckbereich ein Sperrteil 13 eingesetzt.FIG. 2 shows a push button switch 1 with a
Aus den Figuren 3 bis 5 sind verschiedene Kombinationsmöglichkeiten für das Anbringen der Bedienfelder in unterschiedlicher Zahl aufgezeigt. Die Bedienfelder können erhaben oder vertieft auf der Deckplatte des Tastenknopfes angebracht sein. Weiterhin können die Bedienfelder als getrenntes Teil, vorzugsweise aus transparentem Material, in die Deckplatte des Tastenknopfes eingesetzt sein. Die Bedienfelder können auch z. B. über sogenannte Lichtleiter gemeinsam oder einzeln beleuchtbar ausgeführt sein. Die Figur 3 zeigt einen Tastenknopf mit fünf Bedienfeldern, die Figur 4 mit vier Bedienfeldern und die Figur5 mit nur drei Bedienfeldern. Die Erweiterung eines Drucktastenschalters dieser Art für neun Bedienfelder ist ebenfalls möglich.Various combination options for attaching the control panels are shown in different numbers from FIGS. 3 to 5. The control panels can be raised or recessed on the cover plate of the button. Furthermore, the control panels can be inserted as a separate part, preferably made of transparent material, in the cover plate of the button. The control panels can also e.g. B. be carried out so-called light guide together or individually illuminated. FIG. 3 shows a button with five control panels, FIG. 4 with four control panels and FIG. 5 with only three control panels. The extension of a push button switch of this type for nine control panels is also possible.
