Abstract

A key set is described, for making contact with an electronic apparatus, for example a video recorder. The special feature of this key set, which may have one or more keys (3), is that it is produced integrally as a plastic injection-moulded part with all the individual elements such as the key (3), the contact plunger (5), the web (7), the hinges (9, 9') and the support (8). The key set (1) is connected by means of the support (8) to an apparatus housing (2) or apparatus chassis such that the push button switches (11) which are arranged on a printed-circuit board (10) mounted in the apparatus can be operated by means of the contact plunger (5). The key set is furthermore designed such that it can be mounted in the apparatus with the minimum labour cost, for example automatically. <IMAGE>

Description

Die Neuerung betrifft einen Tastensatz zur Kontaktbetätigung eines elektronischen Gerätes, insbesondere eines Videorecorders, wobei der Tastensatz aus mehreren Einzeltasten besteht, die einstückig aus Kunststoff gefertigt und über einen Träger verbunden am Gerätegehäuse oder am Gerätechassis befestigt sind, und die Tasten vorzugsweise über einen Kontaktstössel auf einzelne in Reihe auf einer Druckplatte angeordnete Druckschalter einwirken.The innovation relates to a set of buttons for actuating the contact of an electronic device, in particular a video recorder, the set of buttons consisting of several individual buttons, which are made in one piece from plastic and connected to the device housing or to the device chassis via a carrier, and the buttons are preferably connected to individual ones via a contact plunger Apply pressure switches arranged in series on a pressure plate.

Es sind zahlreiche Tastensätze bekannt, die einen geschlossenen Aufbau aufweisen und als kompletter Tastensatz auf ein Gerätechassis oder in ein Gerätegehäuse eingesetzt sind. Diese Tastensätze sind zwar von universeller Verwendbarkeit, jedoch aufwendig und bezüglich der Gestaltung der Tastenknopfform nicht ausreichend flexibel. Weiterhin sind Tastensätze bekannt, deren Einzelteile erst während der Gerätemontage zu einem Tastensatz zusammengesetzt werden. Hierbei übernimmt vorzugsweise das Gerätegehäuse die Führung des Tastenknopfes.Numerous key sets are known which have a closed structure and are used as a complete key set on a device chassis or in a device housing. Although these key sets are of universal use, they are complex and not sufficiently flexible with regard to the design of the key button shape. Furthermore, key sets are known, the individual parts of which are assembled into a key set only when the device is being assembled. Here, the device housing preferably takes over the management of the button.

Nachteilig ist bei einem derartigen Aufbau eines Tastensatzes, daß die Führung des Tastknopfes aufwendig ist oder die Betätigung der einzelnen Tastenknöpfe eines Tastensatzes einen unterschiedlichen Tastendruck erfordern.The disadvantage of such a set of keys is that the operation of the key is complex or the actuation of the individual keys of a set of keys require a different key press.

Aufgabe der Neuerung ist es daher, einen einfachen im Gerät aufgebauten Tastensatz zu schaffen, der aus wenigen Teilen besteht und möglichst automatisch im Gerät zu montieren ist, wobei die Tastenführung der einzelnen Tastenknöpfe weitgehend unabhängig von der Führung durch den Tastenausschnitt im Gehäuse gewährleistet ist.The task of the innovation is therefore to create a simple set of buttons built into the device, which consists of a few parts and is to be installed in the device as automatically as possible, the button guidance of the individual button buttons being largely independent of the guidance provided by the button cutout in the housing.

Zur Lösung der Aufgabe werden neuerungsgemäß die im kennzeichnenden Teil des Ansprüchs 1 angegebenen Maßnahmen vorgeschlagen.To solve the problem, the measures specified in the characterizing part of claim 1 are proposed according to the innovation.

Ein Ausführungsbeispiel wird nachfolgend anhand der Zeichnungen näher erläutert.

  • Fig 1 ist eine Darstellung eines in einem Gerätegehäuse eingesetzten Tastensatzes, wobei nur eine Taste gezeichnet ist,
  • Fig. 2 ist eine Draufsicht auf einen Kunststoffträger eines Tastensatzes, an den die einzelnen Tasten angehängt sind.
An embodiment is explained below with reference to the drawings.
  • 1 is an illustration of a key set used in a device housing, only one key being drawn,
  • Fig. 2 is a plan view of a plastic carrier of a key set to which the individual keys are attached.

Die vereinfacht dargestellte Zeichnung der Fig. 1 zeigt im wesentlichen einen Tastensatz 1 im Schnitt, der in einem Gehäuse 2 eines elektronischen Gerätes eingesetzt ist. Der Tastensatz besteht hierbei aus mehreren aneinander gereihten Tasten, wobei in der dargestellten Figur nur eine Taste 3 vergrößert gezeichnet ist. Die einzelne Taste selbst weist einen Tastenknopf 4 auf, an den sich verlängernd ein Kontaktstössel 5 anschließt. Parallel zum Kontaktstössel ist eine kurze Führungsleiste 6 angebracht. Jede Taste ist über einen unter ca. 45o-60o zur Tastenbetätigungslinie - im dargestellten Beispiel ca. 55o - geneigten Steg 7 mit einem Träger 8 verbunden. Wesentlich ist hierbei, daß der Steg 7 an beiden Anbindungsseiten aus Kunststoff mit allen übrigen Tastenteilen einstückig gespritztes Filmscharnier 9 und 9′ aufweist. Über den Träger 8 ist die Taste 3 mit dem Gehäuse 2 verbunden. Senkrecht zur Betätigungsrichtung der Taste 3 ist im Gehäuse 2 und von diesem gehalten, eine Druckplatte 10 eingesetzt. Auf der Druckplatte ist in Reihe und jeweils einem Kontaktstössel zugeordnet, wenigstens ein Druckschalter 11 aufgesetzt und mit der Druckplatte verlötet.The simplified drawing of FIG. 1 essentially shows a button set 1 in section, which is inserted in a housing 2 of an electronic device. The key set here consists of several keys arranged in a row, only one key 3 being shown enlarged in the figure shown. The individual key itself has a key button 4, which is extended by a contact plunger 5. A short guide bar 6 is attached parallel to the contact plunger. Each key is connected via a below about 45 o -60 o to key operation line - connected inclined web 7 with a support 8 - in the example shown about 55 o. It is essential here that the web 7 on both connection sides made of plastic with all other key parts integrally molded film hinge 9 and 9 '. The key 3 is connected to the housing 2 via the carrier 8. A pressure plate 10 is inserted perpendicular to the direction of actuation of the button 3 in the housing 2 and held by this. On the pressure plate, a contact plunger is assigned in series and in each case, at least one pressure switch 11 is attached and soldered to the pressure plate.

Wird nun die Taste 3 betätigt, so verleihen die Lage der Filmscharniere 9, 9′ der Taste eine nahezu senkrechte Bewegung in Richtung des Druckschalters 11, und der Tastenknopf kann sich gegenüber dem vorgesehenen Ausschnitt im Gehäuse 2 reibungsfrei bewegen.If the button 3 is now pressed, the position of the film hinges 9, 9 'give the button an almost vertical movement in the direction of the pressure switch 11, and the button can move smoothly relative to the cutout provided in the housing 2.

Aus der Fig. 2 ist ferner zu ersehen, daß der einzelne Tastenknopf zur Unterscheidung verschiedener Gerätefunktionen, die über den jeweiligen Tastenknopf betätigt werden können, eine unterschiedliche Tastenbreite aufweisen kann. Weiterhin ist der Tastenknopf vorzugsweise von zwei parallel angeordneten Stegen 7 mit dem Träger 8 verbunden.From Fig. 2 it can also be seen that the individual button to distinguish different device functions that can be operated via the respective button can have a different key width. Furthermore, the button is preferably connected to the carrier 8 by two webs 7 arranged in parallel.
