Eine Ausführungsvariante des erfindungsgemäßen Tastenmoduls sieht ein Aufsteckelement vor. Dieses Aufsteckelement weist ein Trägerelement auf, an dem das erste Dämpfungselement und das zweite Dämpfungselement angebracht sind. Ferner weist das Trägerelement Einrichtungen zum Aufstecken des Aufsteckelements auf eine Außenseite des Gehäuses des Tastenmoduls auf. Das Aufsteckelement bildet somit das für die Geräuschdämpfung zuständige Element des Tastenmoduls. Auf diese Weise können auch bekannt Tastenmodule, beispielsweise die eingangs angesprochenen MX-Tastenmodule, zur Dämpfung der Anschlaggeräusche zu einem erfindungsgemäßen Tastenmodul umgerüstet werden. Die Schaltcharakteristik wird durch das Aufsteckmodul nicht oder zumindest nahezu nicht verändert.A variant of the key module according to the invention provides a slip-on. This slip-on element has a carrier element on which the first damping element and the second damping element are mounted. Further, the support member has means for attaching the Aufsteckelements on an outer side of the housing of the key module. The plug-on element thus forms the responsible for the noise damping element of the key module. In this way, known button modules, for example the MX button modules mentioned at the beginning, can be converted to a damping module according to the invention for damping the striking noises. The switching characteristic is not or at least almost unchanged by the piggyback.
Das Aufsteckelement umfassend Trägerelement und erstes Dämpfungselement und zweites Dämpfungselement kann beispielsweise mittels Zwei-Komponenten-Spritzgießtechnik hergestellt sein. Dies ermöglicht eine kostengünstige Herstellung.The slip-on element comprising carrier element and first damping element and second damping element can be produced, for example, by means of two-component injection molding technology. This allows a cost-effective production.
Die Einrichtungen zum Aufstecken des Aufsteckelements auf die Außenseite des Gehäuses können beispielsweise als Rastelemente ausgebildet sein. Diese Rastelemente sind so ausgestaltet, dass sie mit dem Gehäuse zur Ausbildung einer festen Verbindung verrastbar oder verrastet sind. Dies ermöglicht eine feste und sichere Positionierung des Aufsteckelements mit den Dämpfungselementen an dem Gehäuse des Tastenmoduls, ein Verrutschen wird dadurch verhindert. Auch können ein oder mehrere der Rastelemente als Führungsnasen ausgebildet sein, die derart geformt sind, dass bereits beim Aufstecken des Aufsteckelements auf das Gehäuse das Aufsteckelement so geführt wird, dass es die vorgesehene Position am Gehäuse einnimmt und die Einnahme einer fehlerhaften Position verhindert ist. Dadurch wird die korrekte Montage und Positionierung des Aufsteckelements zum einen sichergestellt und zum anderen erleichtert.The means for attaching the Aufsteckelements on the outside of the housing may be formed for example as latching elements. These locking elements are designed such that they can be latched or latched to the housing to form a solid connection. This allows a firm and secure positioning of the Aufsteckelements with the damping elements on the housing of the key module, slipping is thereby prevented. Also, one or more of the locking elements may be formed as guide lugs, which are shaped such that even when plugging the Aufsteckelements on the housing, the plug-in element is guided so that it occupies the intended position on the housing and the receipt of a faulty position is prevented. As a result, the correct mounting and positioning of the slip-on is ensured on the one hand and on the other hand.
Das Trägerelement des Aufsteckelements kann beispielsweise aus Kunststoff, insbesondere aus den Kunststoffen ABS oder PA oder PP oder einem Kunststoff-Compound umfassend einen oder mehrere der vorgenannten Kunststoffe, bestehen oder diesen Kunststoff umfassen.The carrier element of the slip-on element can consist for example of plastic, in particular of the plastics ABS or PA or PP or a plastic compound comprising one or more of the aforementioned plastics, or comprise this plastic.
Das Aufsteckelement kann auch derart ausgebildet sein, dass es in einem am Gehäuse des Tastenmoduls angebrachten Zustand den Stößel des Tastenmoduls zumindest in dessen oberer Anschlagposition ringförmig umgibt.The plug-on element can also be designed such that in a state attached to the housing of the button module it surrounds the plunger of the button module in a ring shape at least in its upper stop position.
Alternativ zu der vorbeschriebenen Ausführungsvariante des Tastenmoduls mit einem Aufsteckelement sieht eine weitere Ausführungsvariante des Tastenmoduls vor, dass das erste Dämpfungselement und das zweite Dämpfungselement, und damit gegebenenfalls auch das einstückige Dämpfungselement, direkt am Gehäuse ausgebildet sind. Insbesondere können Gehäuse und erstes Dämpfungselement und zweites Dämpfungselement, und damit gegebenenfalls auch das einstückige Dämpfungselement, gemeinsam mittels Zwei-Komponenten-Spritzgießtechnik hergestellt sein. Im Unterschied zur vorbeschriebenen Ausführungsvariante sieht diese Variante somit die direkte Integration der Dämpfungselemente in das Gehäuse des Tastenmoduls vor, die Verwendung eines zusätzlichen Bauteils, beispielsweise des vorstehend und nachfolgend beschriebenen Aufsteckelements, entfällt somit in dieser Variante.As an alternative to the above-described embodiment variant of the key module with a plug-on element, a further embodiment of the key module provides that the first damping element and the second damping element, and thus optionally also the one-piece damping element, are formed directly on the housing. In particular, housing and first damping element and second damping element, and thus possibly also the one-piece damping element, can be produced jointly by means of two-component injection molding technology. In contrast to the above-described embodiment, this variant thus sees the direct integration the damping elements in the housing of the key module before, the use of an additional component, for example, the above and below described slip-on, thus omitted in this variant.
Insgesamt werden mit dem erfindungsgemäßen Tastenmodul Lösungen vorgeschlagen, die eine deutliche Reduzierung der Anschlaggeräusche und damit der Tippgeräusche bei Tastaturen mit sich bringen, und zwar sowohl eine Reduzierung der beim Betätigen der Tasten entstehenden Anschlaggeräusche als auch der beim Loslassen der Tasten entstehenden Anschlaggeräusche.Overall, solutions are proposed with the key module according to the invention, which bring a significant reduction of the impact noise and thus the typing noise in keyboards, both a reduction in the sound generated when pressing the keys as well as the release of the keys resulting impact noises.
Die vorgeschlagenen Lösungen ermöglichen eine feste und sichere Positionierung des oder der Dämpfungselemente an dem Tastenmodul. Die Lösungen bieten ferner eine lange Lebensdauer und gewährleisten eine zumindest nahezu unveränderte Schaltcharakteristik im Vergleich zu nicht mit den Dämpfungselementen ausgestatteten vergleichbaren Tastenmodulen.The proposed solutions enable a firm and secure positioning of the damping element (s) on the key module. The solutions also offer a long life and ensure an at least almost unchanged switching characteristics compared to not equipped with the damping elements comparable key modules.
Die erfindungsgemäßen Tastenmodule mit den Aufsteckelementen ermöglichen eine einfache Montage der Tastenmodule, auch eine Nachrüstung von Tastenmodulen, auch den eingangs genannten Tastenmodulen, beispielsweise den MX-Tastenmodulen, mit den Aufsteckelementen ist möglich. Die Montage ist einfach und kann auch von fachfremden Personen ausgeführt werden.The key modules according to the invention with the Aufsteckelementen allow easy installation of the key modules, including retrofitting of key modules, and the aforementioned key modules, such as the MX key modules, with the Aufsteckelementen is possible. The installation is simple and can be performed by non-specialist persons.
Die vorgeschlagenen Lösungen haben weiter den Vorteil, dass sie keine zwischen den einzelnen Tastenmodulen in einer Tastatur vorgesehenen Zwischenräume beanspruchen, der Tastaturaufbau wird diesbezüglich nicht verändert.The proposed solutions also have the advantage that they do not claim any spaces provided between the individual key modules in a keyboard, the keyboard layout is not changed in this respect.
Schließlich können die Aufsteckelemente der vorgeschlagenen Lösungen, aber auch die Gehäuse der vorgeschlagenen Tastenmodule, kostengünstig durch übliche Kunststoffspritzverfahren hergestellt werden.Finally, the slip-on elements of the proposed solutions, but also the housing of the proposed key modules, can be produced inexpensively by conventional plastic injection molding.
