Description

Die Erfindung betrifft eine Drucktastenschalteinrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a push button switch device according to the preamble of claim 1.

Bei elektronischen Geräten der Unterhaltungselektronik wie Fernsehgeräten, Videorecordern, Audiogeräten und dgl. geht die Tendenz zu immer kompakteren Geräten. Dem entgegen wirkt die Tatsache, daß an solche Geräte immer höhere Anforderungen gestellt werden, d.h. zusätzlich mehr Funktionen erfüllt werden sollen und immer mehr Bedienungskomfort erwartet wird. Das wiederum bedingt, trotz Miniaturisierung der Bauteile, immer größere Gerätegehäuse, insbesondere zur Unterbringung der zur Erfüllung der genannten Forderungen notwendigen Bauteile wie Schalter, Schaltaggregate und Bedienelemente. Zudem wird zur Erhöhung des Bedienungskomforts erwartet, daß die Bedienelemente in möglichst übersichtlicher Weise leicht bedienbar angeordnet sind.With electronic devices in consumer electronics such as televisions, video recorders, audio devices and the like, there is a tendency towards ever more compact devices. This is counteracted by the fact that ever higher demands are placed on such devices, i.e. in addition, more functions are to be fulfilled and more and more ease of use is expected. This in turn, despite the miniaturization of the components, requires ever larger device housings, in particular to accommodate the components such as switches, switching assemblies and operating elements necessary to meet the requirements mentioned. In addition, in order to increase the ease of use, it is expected that the control elements are arranged so that they are easy to operate in the clearest possible way.

Geräte der eingangs genannten Art erfüllen mehr oder weniger die genannten Forderungen. Die Hersteller dieser Geräte gehen in den meisten Fällen den Weg, die notwendigen Schalter und Schaltaggregate möglichst in der Nähe der Bedienelemente anzuordnen, um eine möglichst direkte Betätigung dieser Schalter zu gewährleisten. Das jedoch führt dazu, daß Leiterplatten, die in der Regel die Schalter oder Schaltaggregate tragen, an Stellen im Gerätegehäuse angeordnet werden müssen, an denen sie zwangsläufig eine Vergrößerung des gesamten Geräts bewirken.Devices of the type mentioned initially more or less meet the requirements mentioned. The manufacturers of these devices, in most cases, go the route that arrange the necessary switches and switchgear assemblies as close as possible to the controls to ensure that these switches are operated as directly as possible. However, this means that printed circuit boards, which usually carry the switches or switching assemblies, must be arranged at locations in the device housing where they inevitably cause the entire device to be enlarged.

Der Erfindung liegt die Aufgabe zugrunde, eine Drucktastenschalteinrichtung derart auszugestalten, daß das Gesamtvolumen des entsprechenden Geräts so klein wie möglich ist und trotzdem auch die Übersichtlichkeit der Bedienelemente gewährleistet ist.The invention is based on the object of designing a push button switching device in such a way that the total volume of the corresponding device is as small as possible and nevertheless the clarity of the operating elements is ensured.

Die Aufgabe wird bei einer gattungsgemäßen Drucktastenschalteinrichtung durch die im Anspruch 1 gekennzeichneten Merkmale gelöst.The object is achieved in a generic push button switching device by the features characterized in claim 1.

Die Drucktastenschalteinrichtung gemäß der Erfindung weist den Vorteil auf, daß zur Erzielung einer kompakten Geräteform der zur Verfügung stehende Raum optimal genutzt wird. Das bedeutet, daß Schalter oder Schaltaggregate dort untergebracht sind, wo ein möglichst großer Gerätefüllfaktor erreicht wird, z.B. neben, hinter oder zwischen relativ großen Bauteilen wie Relais, Steckmodulen, Displays und dgl.. Zur Betätigung dieser Schalter durch die Bedienelemente sind gemäß der Erfindung Umlenkelemente, hier als Zwischenglieder bezeichnet, vorgesehen.The push button switch device according to the invention has the advantage that the space available is optimally used to achieve a compact device shape. This means that switches or switching units are accommodated where the greatest possible device fill factor is achieved, for example next to, behind or between relatively large components such as relays, plug-in modules, displays and the like. To actuate these switches by the control elements are deflection elements according to the invention , referred to here as intermediate links, is provided.

Umlenkelemente bzw. Zwischenglieder zur Umlenkung der Betätigungseinrichtung sind an sich dem Fachmann bekannt. Bei der Erfindung werden jedoch die Zwischenglieder so ausgestaltet, daß sie zum einen die durch die Lage der Schalter zwangsbedingte Umlenkung der Tastenbetätigungsrichtung ausführen und zum anderen integraler Bestandteil des Gerätechassis bzw. darauf befestigter anderer Bauteile sind.Deflection elements or intermediate elements for deflecting the actuating device are known per se to the person skilled in the art. In the invention, however, the intermediate links are designed such that they on the one hand carry out the redirection of the button actuation direction due to the position of the switches and on the other hand are an integral part of the device chassis or other components fastened thereon.
