The pushbutton configuration is preferably formed in one piece from readily flowing polyacetal, which has a high rigidity and restoring elasticity.

Description

Beschreibung description
Entkoppelte DrucktastenDecoupled pushbuttons
Die Erfindung betrifft eine einstückige Drucktastenanordnung mit mindestens zwei benachbarten Drucktasten, Federbeinen und Verbindungsstegen, die weitestgehend gewährleistet, daß bei Bedienung einer Drucktaste benachbarte Tasten sich nur .äußerst geringfügig mit bewegen.The invention relates to a one-piece pushbutton arrangement with at least two adjacent pushbuttons, struts and connecting webs, which largely ensures that when a pushbutton is operated, adjacent keys move only very little.
Im Zuge der allgemeinen Tendenz zur Vereinfachung von Produktionsabläufen werden zunehmend Baugruppen, die früher aus Einzelteilen zusammengesetzt wurden, heute als integrale Einheiten gefertigt. Dies trifft auch auf Einheiten aus Drucktasten, Tastenhalterungen und Tastenfederungen zu. Nachdem in einem ersten Schritt Tastenhalterungen und Tastenfederungen in einer Federleiste vereinigt wurden, wird nunmehr versucht, auch die Drucktasten mit in diese Einheit zu integrieren, sodaß diese in einem einzigen Verfahrensschritt hergestellt werden kann.In the course of the general tendency to simplify production processes, assemblies that were previously composed of individual parts are increasingly being manufactured as integral units. This also applies to units made of push buttons, key holders and key suspensions. After key holders and key suspensions were combined in a spring strip in a first step, an attempt is now also made to integrate the pushbuttons into this unit, so that it can be produced in a single process step.
Eine Federleiste beschreibt beispielsweise die deutsche Patentschrift DE 3034585, die einen Profilstreifen aus Klammerbügeln zur Aufnahme der Drucktasten und gebogenen, vorzugsweise V-förmigen Verbindungsstegen im Abstand von je zwei Klammerbügeln offenbart. Die Drucktasten werden dabei auf die Klammerbügel aufgesteckt und die flexiblen Verbindungsstege gewährleisten, daß die Drucktasten ohne Schwierigkeiten niedergedrückt werden können. Das Zurückfedern der Tasten nach dem Niederdrücken wird zusätzlich über gesonderte Froschfedern gewährleistet.A female connector describes, for example, the German patent DE 3034585, which discloses a profile strip made of clip brackets for receiving the push buttons and curved, preferably V-shaped connecting webs at intervals of two clip brackets. The push buttons are attached to the clamp bracket and the flexible connecting webs ensure that the push buttons can be depressed without difficulty. The springs spring back after being pressed down is also ensured by separate frog springs.
Eine gestaffelte, als eine Einheit gebildete Anordnung von Federleisten wird in US 4315114 beschrieben. In dieser Anordnung sind die Tasten an je zwei flexiblen Federbeinen angeordnet, die ihrerseits an steifen Verbindungsstegen angeformt sind.A staggered, unitary arrangement of female connectors is described in US 4315114. In this arrangement, the keys are arranged on two flexible struts, which in turn are formed on rigid connecting webs.
Ein Telefontastenblock mit in eine Federleiste integrierten mehrreihigen Bedientasten wird in European Plastics News, No. 10, 1983, Seite 63 beschrieben. Dieser Tastenblock wird dadurch hergestellt, daß in einem ersten Spritzgußschritt ein Teil der Tasten geformt wird und in einem zweiten Spritzgußschritt die Tasten vervollständigt und mit einem die Tasten verbindenden Rahmen versehen werden. Zur flexiblen Bedienung der Tasten sind diese über bewegliche Beine mit dem steiferen Teil des Rahmens verbunden.A telephone keypad with multi-row control keys integrated in a female connector is described in European Plastics News, No. 10, 1983, page 63. This key block is produced by molding part of the keys in a first injection molding step and completing the keys in a second injection molding step and providing them with a frame connecting the keys. For flexible operation of the buttons, they are connected to the stiffer part of the frame via movable legs.
In US 5270507 ist eine Drucktastenanordnung offenbart, bei der benachbarteUS 5270507 discloses a push button arrangement in which adjacent ones
Drucktasten Über Stege miteinander verbunden sind. Die Stege sind dabei an ihren den Drucktasten zuweisenden Enden als Federbeine ausgearbeitet, so daß die Drucktasten über die federnden Teile der Stege beweglich gelagert sind und die gesamte Drucktastenanordnung auf den zwischen den Federbeinen liegenden Abschnitten der Stege auf einer Unterlage ruhen kann. Die gesamte Drucktastenanordnung ist aus einem Kautschuk gefertigt. Die Dicke der Stege ist auf ihrer gesamten Länge im wesentlichen konstant.Pushbuttons are connected to each other by bars. The webs are designed at their ends facing the pushbuttons as spring struts, so that the pushbuttons are movably mounted over the resilient parts of the webs and the entire pushbutton arrangement can rest on a base on the sections of the webs lying between the spring struts. The entire push button arrangement is made of a rubber. The thickness of the webs is essentially constant over their entire length.
Allgemein soll durch die Ausbildung von Federbeinen für die Drucktasten sowie durch flexible Verbindungsstege zwischen benachbarten Drucktasten erreicht werden, daß bei Bedienung einer Drucktaste benachbarte Tasten sich nicht bewegen, wobei unter Umständen ein ungewollter Kontakt oder Schalteffekt ausgelöst werden könnte. Da diese Entkoppelung zwischen benachbarten Drucktasten noch nicht einwandfrei gelöst werden konnte, bestand die Aufgabe, durch weitere konstruktive Änderungen die Entkoppelung zu verbessern.In general, the design of spring struts for the pushbuttons and flexible connecting webs between adjacent pushbuttons means that adjacent pushbuttons do not move when a pushbutton is operated, an undesired contact or switching effect possibly being triggered. Since this decoupling between neighboring pushbuttons could not yet be solved properly, the task was to improve the decoupling by further design changes.
Nachteilig bei den bereits beschriebenen Drucktastenanordnung ist, daß die Federwirkung der Federbeine unmittelbar mit der Stärke der Verbindungsstege zusammenhängt. Bei einer Verstärkung der Federwirkung wird also stets auch die Kopplung der Drucktasten aneinander verstärkt.A disadvantage of the push button arrangement already described is that the spring action of the struts is directly related to the strength of the connecting webs. When the spring action is increased, the coupling of the pushbuttons to one another is also always increased.
Aufgabe der vorliegenden Erfindung ist es, durch einfache konstruktive Maßnahmen die Nachteile des Standes der Technik zu beheben. Diese Aufgabe wird gelöst durch eine Drucktastenanordnung mit wenigstens zwei benachbarten zueinander angeordneten Drucktasten, die durch Verbindungsstege zu einer Einheit verbunden sind, dadurch gekennzeichnet, daß jede der Drucktasten (2) zwei Federbeine (4) besitzt, die sich an einer Auflagefläche abstützen. Durch die vorliegende Anordnung von Federbeinen und Verbindungsstegen sind zwei voneinander unabhängige Funktionselemente geschaffen, die sich im Hinblick auf ihre eigentliche Aufgabe und Funktion zweckmäßig ausbilden lassen, ohne daß dies eine funktionsbeeinträchtigende Beeinflussung zwischen den beiden Bauteilen zur Folge hat. Die Funktionssicherheit der Tastenanordnung ist folglich erheblich verbessert. Die Rückstellkraft, die die Federbeine auf die Drucktaste ausübt kann also unabhängig von den Verbindungsstegen bewirkt werden. Die Verbindungsstege können bei der erfindungsgemäßen Drucktastenanordnung also frei dimensioniert werden, da die Federwirkung unabhängig von der Dicke der Verbindungsstege ist und von der Beschaffenheit der Federbeine abhängt. Vorteilhaft ist weiter, daß die mechanische Entkopplung benachbarter Drucktasten möglich ist, so daß sich bei Bedienung einer Drucktaste benachbarte Tasten nicht bewegen und kein ungewollter Kontakt oder Schalteffekt einer benachbarten Taste ausgelöst wird. In einer vorteilhaften Ausführung der vorliegenden Erfindung sind die Federbeine an jeder Drucktaste seitlich versetzt zueinander angeordnet, bevorzugt besitzen die Drucktasten einen Boden, an dem die Federbeine vorgesehen sind. Bevorzugt sind die Federbeine flachprofilig ausgebildet und stützen sich mit ihrem freien Ende an der Auflagefläche ab. Das freie Ende der Federbeine besitzt bevorzugt einen parallel zur Auflagefiäche abgesetzten abschnitt, der sich an der Auflagefläche abstützt. Die Federbeine können sich außerdem vom Boden der Drucktasten (2) unter die Drucktastenanordnung erstrecken.The object of the present invention is to eliminate the disadvantages of the prior art by simple design measures. This object is achieved by a pushbutton arrangement with at least two adjacent pushbuttons which are connected to one another by connecting webs, characterized in that each of the pushbuttons (2) has two spring struts (4) which are supported on a support surface. The present arrangement of struts and connecting webs creates two mutually independent functional elements which can be appropriately designed with regard to their actual task and function without this having an adverse effect on the function between the two components. The functional reliability of the key arrangement is therefore considerably improved. The restoring force exerted by the struts on the push button can therefore be effected independently of the connecting webs. The connecting webs can thus be freely dimensioned in the push button arrangement according to the invention, since the spring action is independent of the thickness of the connecting webs and depends on the nature of the struts. Another advantage is that the mechanical decoupling of adjacent push buttons is possible, so that when a push button is operated, adjacent buttons do not move and no unwanted contact or switching effect of an adjacent button is triggered. In an advantageous embodiment of the present invention, the spring struts on each pushbutton are arranged laterally offset from one another; the pushbuttons preferably have a base on which the spring struts are provided. The spring struts are preferably of flat profile and are supported with their free end on the contact surface. The free end of the spring struts preferably has a section which is offset parallel to the support surface and which is supported on the support surface. The struts can also extend from the bottom of the push buttons (2) under the push button arrangement.
In einer vorteilhaften Ausführung sind die Verbindungsstege flexibel ausgeführt. Besonders vorteilhaft weisen die Verbindungsstege eine Verjüngung auf, die entweder auf der der Drucktasten zugewandten Oberseite, der Unterseite oder den Seitenflächen der Verbindungsstege vorgesehen ist. Bevorzugt ist die Verjüngung in der Mitte des Verbindungssteges zwischen den Drucktasten vorgesehen. Besonders bevorzugt ist die Verjüngung als Filmscharnier ausgebildet, ganz besonders bevorzugt sind die Verbindungsstege in Form von sich verjüngenden Filmscharnieren ausgeprägt. Besonders vorteilhaft wird die erfindungsgemäße Drucktastenanordnung aus einem besonders steifen Polyacetalpolymeren mit hoher Rückstellkraft hergestellt. Hierbei lassen sich die Verbindungsstege bis auf 0,2 mm verjüngen, ohne daß bei dauerhaftem Gebrauch der Tasten an den Verjüngungsstellen ein Bruch der Verbindungsstege zu befürchten wäre. Durch die Verwendung eines leicht fließenden Polyacetals (Hostaform® C 13031 , Ticona GmbH, Frankfurt) wird zudem ermöglicht, daß die Drucktasteneinheit trotz der den Durchfluß des Kunststoffs behindernden Verjüngungen in einemIn an advantageous embodiment, the connecting webs are flexible. The connecting webs particularly advantageously have a taper, which is provided either on the upper side facing the pushbuttons, on the lower side or on the side surfaces of the connecting webs. The taper is preferably provided in the middle of the connecting web between the push buttons. The taper is particularly preferably designed as a film hinge, and the connecting webs are very particularly preferably in the form of tapered film hinges. The push button arrangement according to the invention is particularly advantageously produced from a particularly rigid polyacetal polymer with a high restoring force. Here, the connecting webs can be tapered down to 0.2 mm without fear of breaking the connecting webs if the buttons at the tapering points are used continuously. The use of an easy-flowing polyacetal (Hostaform® C 13031, Ticona GmbH, Frankfurt) also makes it possible for the push button unit to be integrated in one, despite the tapering which hinders the flow of the plastic

Figur 1 zeigt einen Ausschnitt aus einer einreihigen Drucktastenanordnung 1 von Drucktasten 2, die über Verbindungsstege 3 miteinander verbunden sind. An den Drucktasten 2 befinden sich je zwei Federbeine 4, die sich vom Boden der Drucktasten 3 unter die Drucktastenanordnung 1 hin erstrecken. Die Federbeine 4 dienen zur Auflage der Drucktastenanordnung 1 auf eine nicht gezeigte Auflagefläche oder einen Rahmen und zur Rückstellung der Drucktaste nach dem Niederdrücken. Die Verbindungsstege 3 weisen in ihrer Mitte eine Verjüngung auf. Diese Verjüngung ist in der Abbildung auf der den Drucktasten zugewandten Oberseite der Verbindungsstege ausgeführt, sie kann aber auch an der Unterseite oder von beiden Seiten her ausgeführt werden. Die einreihige Drucktastenanordnung 1 kann mit anderen Drucktastenreihen oder einem Rahmen verbunden werden.FIG. 1 shows a section of a single-row push button arrangement 1 of push buttons 2, which are connected to one another via connecting webs 3. There are two spring struts 4 each on the pushbuttons 2, which struts extend from the bottom of the pushbuttons 3 under the pushbutton arrangement 1. The spring struts 4 serve to rest the pushbutton arrangement 1 on a support surface (not shown) or a frame and to reset the pushbutton after it has been depressed. The connecting webs 3 have a taper in their center. This taper is shown in the illustration on the top of the connecting webs facing the pushbuttons, but it can also be carried out on the bottom or from both sides. The single row push button arrangement 1 can be connected to other push button rows or a frame.
An einer Drucktastenanordnung gemäß Figur 1 mit Verbindungsstegen der Länge 6,2 mm, der Breite 1 mm und einer Stegdicke von 0,8 mm am Tastenende bzw. von 0,35 mm in der Verjüngung kann mit FEM-Berechnungen beispielsweise gezeigt werden, daß bei einer Verformung (Niederdrücken) einer Drucktaste um 1,25 mm die benachbarten Drucktasten um nur 0,35 mm mit bewegt werden. Ist der Steg in seiner ganzen Länge 0,8 mm dick, so werden bei gleicher Verformung einer Drucktaste die benachbarten Drucktasten um 0,63 mm mit bewegt. In den Berechnungen wurden die Materialeigenschaften von ©Hostaform C 13031 (Ticona GmbH) mit berücksichtigt.On a push button arrangement according to FIG. 1 with connecting webs of length 6.2 mm, width 1 mm and a web thickness of 0.8 mm at the end of the button or 0.35 mm in the taper, FEM calculations can be used to show, for example, that at a deformation (depression) of a push button by 1.25 mm, the adjacent push buttons are also moved by only 0.35 mm. If the entire length of the web is 0.8 mm, the adjacent push buttons are moved by 0.63 mm with the same deformation of a push button. The material properties of © Hostaform C 13031 (Ticona GmbH) were also taken into account in the calculations.
Figur 2 zeigt einen Ausschnitt aus einer zweidimensionalen Drucktastenanordnung 5 von Drucktasten 6, die über Verbindungsstege 7 miteinander verbunden sind, wobei die Drucktasten 6 über die Federbeine 8 beweglich gelagert sind. Die erfindungsgemäße Drucktastenanordnung kann je nach Bedarf als Tastenpaar, -gruppe, -reihe oder zweidimensionale Tastenanordnung ausgeführt sein. Anwendung findet eine derartige Drucktastenanordnung beispielsweise in Bedienfeldern von Haushaltsgeräten, insbesondere sogenannten Weißgeräten wie Waschmaschinen, Kühlschränke, Wäschetrockner, Küchenherde etc., als Tastaturen für Rechenmaschinen, Schreibmaschinen, Computer und Telefonen, insbesondere Mobiltelefone, Notebooks etc., Bedienfelder für Radio-, Musik-, Video- und TV-Geräte, Bedienfelder für Maschinen und Werkzeugmaschinen oder Fahrstühle, Schalt- und Bedienfelder in Fahrzeugen etc.FIG. 2 shows a section of a two-dimensional pushbutton arrangement 5 of pushbuttons 6, which are connected to one another via connecting webs 7, the pushbuttons 6 being movably mounted via the spring struts 8. The push button arrangement according to the invention can be designed as a pair, group, row or two-dimensional key arrangement as required. Such a push button arrangement is used, for example, in control panels of household appliances, in particular so-called white appliances such as washing machines, refrigerators, tumble dryers, kitchen stoves etc., as keyboards for calculating machines, typewriters, computers and telephones, in particular mobile telephones, notebooks etc., control panels for radio and music , Video and TV devices, control panels for machines and machine tools or elevators, control and control panels in vehicles etc.
