Abstract

Push-button assembly for electrical communications equipment, esp. car radios, cassette tape players etc. and consists of a number of push-buttons all mounted in a single, common flexible support. Support is a flat plate (7) extending between two end suspension zones (19,17) and having the individual push buttons (5) clamped in it at the desired distance above the relevant switching point (25) located below the support plane (21). As each push button is pressed down, the support strip (7) deflects in its local strip sections (15) to permit this movement out of the support plant. With this arrangement, the push buttons are accurately located in position and do not deflect sideways when pressed down. The strip (7) is pref. profiled so that clamps (9) are formed into which the push buttons can be snapped, the arms of the clamps being connected together by connecting webs (15), pref. of V-shape. Pref. the strip (7) is of polyoxymethylene or polyacetal of 1mm thickness.

Description

"Drucktastenanordnung in einem Gerät der elektrischen"Push button arrangement in an electrical device

Nachrichtentechnik" Die Erfindung bezieht sich auf eine Drucktastenanordnung in einem Gerät der elektrischen Nachrichtentechnik, das insbesondere für Fahrzeuge geeignet ist, bei dem über Drucktasten Gerätefunktionen auslösbar sind und die Drucktasten mittels einer gemeinsamen Halterung gehalten und Schaltpunkten zugeordnet sind. Communications technology "The invention relates to a push button arrangement in a device for electrical communications engineering, in particular for vehicles is suitable in which device functions can be triggered via pushbuttons and the pushbuttons held by means of a common bracket and assigned switching points.

Bei elektronischen, mit Berührungskontakten arbeitenden elektrischen Geräten, wie Fahrzeugrundfunkempfängern, Funkgeräten, Kassettenrecordern, ist es notwendig, die mit Schaltpunkten zusammenwirkenden Drucktasten genau oberhalb der Schaltpunkte in einer Tragebene zu haltern. Dieses Haltern ist möglich mit Hilfe von Siliconkautschukstreifen, in die Drucktasten in vorgegebenem Abstand nebeneinander eingesetzt sind. Ei.n relativ elastischer Siliconkautschukstreifen hat jedoch den Nachteil, daß die gegenseitigen Abstände der Drucktasten bei der einspannenden Aufhängiing eines solchen Streifens und der damit verbundenen Streifenlängung nicht mehr genau mit den Schaltpunkten fluchten. Zudem neigt ein hochelastischer Siliconkautschukstreifen zu einem In-sich-Krümmen zwischen den Aufhängungen. Schließlich ist das Siliconkautschukstreifen-Material relativ kostenaufwendig.In the case of electronic electrical ones that work with touch contacts Devices such as car radio receivers, radios, cassette recorders, it is necessary, the pushbuttons interacting with switching points just above the To keep switching points in a supporting plane. This holding is possible with the help of silicone rubber strips, into the pushbuttons next to each other at a specified distance are used. However, a relatively elastic silicone rubber strip has the Disadvantage that the mutual spacing of the pushbuttons in the clamping suspension such a strip and the associated strip elongation are no longer accurate align with the switching points. In addition, a highly elastic silicone rubber strip tends to to a bend in itself between the suspensions. Finally, this is the silicone rubber strip material relatively expensive.

Es ist Aufgabe der Erf indung, eine Drucktastenanordnung zu schaffen, die bei Vermindenung der eingesetzten Materialkosten ein genaues Fluchten der Drucktasten mit den Schaltpunkten sicherstellt.It is the task of the invention to create a pushbutton arrangement the precise alignment of the pushbuttons while reducing the material costs used with the switching points.

Die gestellte Aufgabe ist bei einer Drucktastenanordnung der eingangs erwähnten Art erfindungsgemäß dadurch gelöst, daß die gemeinsame Halterung für die Drucktasten aus einem sich zwischen Aufhängestellen an seinen Enden eben haltenden Profilhaltestreifen besteht, der die in ihn eingeklemmten Drucktasten im ge1^Enschten Abstand in einer Tragebene oberhalb der Schaltpunkte haltert, aus der jede Drucktaste einzeln unter Nachgeben der beiderseits von ihr gelegenen Streifenabschnitte in die Schaltpunktebene niederdrückbar ist.In the case of a pushbutton arrangement, the problem posed is the one at the beginning mentioned type according to the invention solved in that the common holder for the Pushbuttons from one that is held between suspension points at its ends Profile retaining strip consists of the pushbuttons clamped in it Distance in a supporting plane above the switching points from which each pushbutton is held individually while yielding the strip sections located on both sides of it in the switching point level can be depressed.

Ein solcher Profilkunststoffstreifen, der sich zwischen den Aufhängestellen an seinen Enden selbst eben hält und in Längsrichtung keiner Spannung unterworfen wird, ermöglicht ein genaues Fluchten der Drucktasten mit den Schaltpunkten. Dies ist eine wesentliche Voraussetzung für eine einwandfreie Gerätefunktion.Such a profile plastic strip, which is between the suspension points holds even at its ends and is not subjected to any tension in the longitudinal direction enables precise alignment of the pushbuttons with the switching points. this is an essential prerequisite for proper device function.

Nach einer weiteren Ausgestaltung der Erfindung ist der Profilhaltestreifen in der Art profiliert, daß in vorgegebenen Abständen einzelne Drucktasten eingeschnappt sind und daß die Klammerbügel miteinander über gebogene Verbindungsstege verbunden sind. Die Verbindungsstege zwischen den Klammerbügeln können dabei eine V-förmige Form aufweisen. Durch die Verwendung von gebogenen Verbindungsstegen wird der Streifen zwischen den Elammerbügeln so elastisch, daß die einzelnen Drucktasten ohne Schwierigkeiten aus dem Streifen heraus niedergedrückt werden können, um Schaltftu1Iionen zu übernehmen.According to a further embodiment of the invention, the profile retaining strip is profiled in such a way that individual pushbuttons are snapped into place at predetermined intervals are and that the clip brackets are connected to one another via curved connecting webs are. The connecting webs between the clip brackets can be V-shaped Have shape. By using curved connecting webs, the strip becomes so elastic between the clamps that the individual pushbuttons without difficulty can be depressed out of the strip in order to take over switching functions.

ITach einer weiteren Ausgestaltung der Erfindung gestellt der Profilkunststoffstreifen aus Polyoxymethylen, Polyacetal oder einem beliebigen anderen Material mit entsprechenden Eigenschaften. Ein derartiges Kunst- stoffmaterial hat ausreichende Federeigenschaften, die für den Profillsunststoffstreifen vorteilhaft sind.According to a further embodiment of the invention, the profiled plastic strip is provided made of polyoxymethylene, polyacetal or any other material with appropriate Properties. Such an art fabric material has sufficient Spring properties that are advantageous for the profiled plastic strip.
