Abstract
Description
Die Erfindung betrifft eine Drucktastereinrichtung mit einer feststehenden äußeren Tragstruktur und wenigstens einem relativ zu diesem bewegbaren Innenteil zur Betätigung insbesondere elektrischer Schaltkontakte.The invention relates to a push button device with a fixed outer support structure and at least one movable relative to this inner part activity especially electrical switch contacts.
Zur Betätigung elektrischer Komponenten ist es allgemein bekannt, Drucktastereinrichtungen vorzusehen, welche ein fest angeordnetes Gehäuse oder Panel und einen oder mehrere zu diesem relativbewegbare(n) Taster umfassen.For actuating electrical components it is generally known to provide push button devices which a fixed housing or Panel and one or more push buttons that can be moved relative to it include.

Aufgabe der Erfindung ist es, eine eingangs genannte Drucktastereinrichtung bereitzustellen, welche einerseits ein hochwertiges Erscheinungsbild und gute haptische Eigenschaften aufweist, die andererseits eine geringe Bauhöhe aufweist und nur wenige Einzelteilen umfasst, es soll die Möglichkeit bestehen, durch eine geschlossene Oberfläche ein schädliches Eindringen von Schmutz und/oder Feuchtigkeit zu verhindern. Zur Herstellung der Drucktastereinrichtung soll ein besonders einfaches und kostengünstiges Verfahren bereitgestellt werden.The object of the invention is a provide push button device mentioned above, which on the one hand a high-quality appearance and good haptic Features that have a low overall height and includes only a few individual parts, it should be possible through a closed surface a harmful one Prevent dirt and / or moisture from entering. to Production of the push button device should be a particularly simple and cost-effective Procedures are provided.
Die Lösung der Aufgabe erfolgt mit
den Merkmalen des Patentanspruches
Bevorzugte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Preferred refinements and developments the invention are the subject of the dependent claims.
Gemäß eines besonders bevorzugten Ausführungsbeispiels ist zwischen Tragstruktur und dem wenigstens einen Innenteil ein vollständig oder teilweise mit weichelastischem Kunststoff ausgefüllter Bewegungsspalt vorgesehen.According to a particularly preferred embodiment is between the support structure and the at least one inner part Completely or movement gap partially filled with flexible plastic intended.
Insbesondere um das Auswechseln einzelner Drucktaster zu ermöglichen, wird es gemäß eines Ausführungsbeispiels als vorteilhaft angesehen, wenn der mittels weichelastischem Kunststoff mit dem zumindest einen Innenteil verbundene Bereich der Tragstruktur von der weiteren Tragstruktur getrennt ist, so dass vorteilhafterweise die Tragstruktur mehrteilig ausgebildet ist. Dabei ist ein flächig ausgebildeter, mit wenigstens einer Aufnahmeöffnung versehener ersten Teilbereich und wenigstens ein rahmenartig ausgebildeter, mit dem wenigstens einen Innenteil elastisch verbundener zweiter Teilbereich vorgesehen und der wenigstens eine zweite Teilbereich der Tragstruktur ist mit dem ersten Teilbereich verbindbar.Especially when it comes to replacing individuals Pushbuttons to enable it becomes according to an embodiment considered advantageous if the by means of flexible plastic region of the support structure connected to the at least one inner part is separated from the further supporting structure, so that advantageously the support structure is formed in several parts. Here is a flat, with at least one receiving opening provided first partial area and at least one frame-like, with the at least one inner part elastically connected second Sub-area provided and the at least one second sub-area the supporting structure can be connected to the first partial area.
Zweckmäßigerweise sind bei diesem Ausführungsbeispiel der erste Teilbereich und der wenigstens eine zweite Teilbereich der Tragstruktur kraft- bzw. formschlüssig miteinander verbunden.Expedient are with this embodiment the first section and the at least one second section the supporting structure is connected to one another in a non-positive or positive manner.
In Hinblick auf eine gute Tastbarkeit auch ohne Sichtkontakt ist vorteilhafter weise das wenigstens eine Innenteil außenseitig gegenüber der Tragstruktur erhaben.With regard to good palpability even without visual contact, this is advantageously at least one Inner part outside across from of the supporting structure.
Gemäß eines zu bevorzugenden Ausführungsbeispiels weist der den Bewegungsspalt ausfüllende weichelastische Kunststoff einen sich über die Spaltbreite verringernden Querschnitt auf, wodurch eine besonders gute Beweglichkeit des Innenteils gegenüber der Tragstruktur erreicht wird.According to a preferred embodiment shows the flexible plastic filling the movement gap one over the gap width reducing cross-section, making a special good mobility of the inner part relative to the support structure achieved becomes.
Zweckmäßigerweise weist der Kunststoff der Tragstruktur, des Innenteils und der verbindende weichelastische Kunststoff thermoplastische Eigenschaften auf.The plastic expediently has the supporting structure, the inner part and the connecting soft elastic Plastic thermoplastic properties.
Zur Herstellung der Drucktastereinrichtung wird Spritzgießverfahren bevorzugt, bei welchem in einem ersten Spritzgießvorgang der erste thermoplastische Kunststoff der Tragstruktur und des wenigstens einen Innenteiles in mittels wenigstens eines Schiebers voneinander getrennte Formräume eines Spritzgießwerkzeuges eingespritzt, nach ausreichender Verfestigung des ersten Kunststoffes der wenigstens eine Schieber zurückgezogen wird, so dass ein die Tragstruktur und das wenigstens eine Innenteil verbindender Formraum freigegeben wird und in einem zweiten Spritzgießvorgang der elastomer-thermoplastische Verbindungskunststoff eingespritzt wird und dabei haftend und/oder durch Hinterschnitte bedingt formschlüssig sowohl mit der Tragstruktur als auch mit dem wenigsten einem Innenteil verbindet.Injection molding is preferred for the production of the pushbutton device, in which, in a first injection molding process, the first thermoplastic plastic of the support structure and of the at least one inner part is at least one Nes slide molded separate spaces of an injection molding tool injected, after sufficient solidification of the first plastic, the at least one slide is withdrawn so that a mold space connecting the support structure and the at least one inner part is released and in a second injection molding process the elastomer-thermoplastic connecting plastic is injected and thereby adheres and / or due to undercuts positively connects both with the support structure and with at least one inner part.
