Description
Die Erfindung betrifft eine Drucktaste für Rast- und Tastfunktion nach dem Oberbegriff von Anspruch 1 und dient zur Betätigung mindestens eines Kontaktelementes.The invention relates to a push button for latching and key function according to the preamble of claim 1 and is used to actuate at least one contact element.
Aus der Druckschrift CH 595 687 A5 ist eine gattungsgemäße Drucktaste bekannt, die aus einem hohlzylindrischen Gehäuse und einem darin längsverschieblich und unverdrehbar geführten Schaltstößel besteht. Der Schaltstößel ist durch eine schraubenförmige Druckfeder in Richtung Ruhestellung beaufschlagt, wozu Anschlagnasen am Schaltstößel und entsprechende Anschlagflächen am Gehäuse vorgesehen sind. In der Außenwand des Schaltstößels sind eine annähernd herzförmige Rastkulisse und parallel sowie getrennt von dieser eine im wesentlichen in Betätigungsrichtung verlaufende Längsnut eingelassen. Im Gehäuse ist ein im wesentlichen in Betätigungsrichtung verlaufendes, drahtförmiges Federelement gelagert, dessen abgebogenes freies Ende als Führungsstift ausgebildet ist. Zur Realisierung der Rast- oder Tastfunktion verläuft der Führungsstift in der Rastkulisse bzw. in der Längsnut und kann mittels eines spitzen Werkzeuges, das durch eine Zutrittsöffnung im Gehäuse greift, von der Rastkulisse in die Längsnut oder umgekehrt umgesetzt werden. Von Nachteil sind die aufwendige Lagerung sowie die zusätzliche Federmittel beanspruchende und damit raumbeanspruchende Ausführung des Federelementes. Außerdem ist bei der Umsetzung der Führungsstift schwezugänglich und seine tatsächliche Lage nur bei sehr genauem Hinsehen erkennbar.From the document CH 595 687 A5 a generic push button is known, which consists of a hollow cylindrical housing and a longitudinally displaceable and non-rotatably guided switching tappet. The switch plunger is acted upon by a helical compression spring in the direction of rest, including stop lugs on the switch plunger and corresponding stop surfaces are provided on the housing. In the outer wall of the switch plunger an approximately heart-shaped detent gate and parallel to and separated from this one substantially in the direction of actuation extending longitudinal groove are embedded. In the housing a substantially extending in the direction of actuation, wire-shaped spring element is mounted, whose bent free end is formed as a guide pin. To realize the latching or tactile function of the guide pin extends in the detent gate or in the longitudinal groove and can be implemented by means of a pointed tool which engages through an access opening in the housing, from the detent gate into the longitudinal groove or vice versa. The disadvantage is the complex storage and the additional spring means claiming and thus space-consuming design of the spring element. In addition, in the implementation of the guide pin is weldable and its actual situation can only be recognized by a very close look.
Weiterhin ist eine Leuchtdrucktaste mit Rastfunktion der Fa. Moeller GmbH mit der Typenbezeichnung RLTR bekannt, bei der die herzförmige Rastkulisse in der Innenwand des Gehäuses eingelassen ist und der in die Rastkulisse eingreifende Führungsstift nach außen von einem offenen Metallring absteht, der auf dem Schaltstößel gelagert ist. Zur Erhöhung der Zuverlässigkeit ist das Gehäuse mit zwei gegenüber angeordneten Rastkulissen und der Federring mit zwei gegenüber stehenden Führungsstiften ausgestattet.Furthermore, a luminous button with locking function of the company Moeller GmbH with the type designation RLTR is known, in which the heart-shaped detent gate is embedded in the inner wall of the housing and the engaging in the detent guide pin protrudes outward from an open metal ring which is mounted on the switch plunger , To increase reliability, the housing is equipped with two opposing detent gates and the spring ring with two opposing guide pins.
Eine gattungsgemäße Drucktaste US-A-5 262 606 für Tast- und Rastfunktion, besteht aus einem hohlzylindrischen Gehäuse, einem darin längsverschieblich und unverdrehbar geführten Schaltstößel, Federmitteln und Anschlagmitteln zur Einnahme der Ruhestellung, einer annähernd herzförmigen Rastkulisse für die Rastfunktion, einer parallel dazu und zur Betätigungsrichtung verlaufenden Längsnut für die Tastfunktion und einem Führungsstift, der mittels eines in eine Zutrittsöffnung des Gehäuses greifenden Werkzeuges von der Rastkulisse in die Längsnut oder umgekehrt umgesetzt werden kann, wobei die Rastkulisse und die Längsnut an der Innenwand des Gehäuses verlaufen.A generic push button US-A-5 262 606 for tactile and locking function, consists of a hollow cylindrical housing, a longitudinally displaceable and non-rotatably guided switch plunger, spring means and stop means for taking the rest position, an approximately heart-shaped detent gate for the detent function, a parallel thereto and extending to the direction of actuation longitudinal groove for the tactile function and a guide pin which can be implemented by means of a cross into an access opening of the housing tool from the detent gate into the longitudinal groove or vice versa, wherein the detent gate and the longitudinal groove on the inner wall of the housing.
FR-A-2 373 863 zeigt eine Drucktaste für Rastfunktion mit zwei im Schaltstößel ausgebildeten, annähernd herzförmigen Rastkulissen und einem in der Innenwand des hohlzylindrischen Gehäuses in sich verdrehbar gelagerten Ringelement, das mit Führungsstiften radial nach innen in die Rastkulissen greift.FR-A-2 373 863 shows a push button for latching function with two formed in the switch plunger, approximately heart-shaped detent gates and in the inner wall of the hollow cylindrical housing rotatably mounted in the ring element, which engages with guide pins radially inwardly into the detent gates.
Der Erfindung liegt die Aufgabe zugrunde, eine Drucktaste für Rast- und Tastfunktion mit einfacher und raumsparender Halterung des Führungsstiftes sowie mit leicht durchzuführender und erkennbarer Umstellung der Funktionsart anzugeben.The invention has for its object to provide a push-button for locking and Tastfunktion with simple and space-saving mounting of the guide pin and easily carried out and recognizable conversion of the type of function.
Ausgehend von einer Drucktaste der eingangs genannten Art wird die Aufgabe erfindungsgemäß durch die kennzeichnenden Merkmale des unabhängigen Anspruches gelöst, während den abhängigen Ansprüchen vorteilhafte Weiterbildungen der Erfindung zu entnehmen sind.Starting from a push-button of the type mentioned, the object is achieved by the characterizing features of the independent claim, while the dependent claims advantageous developments of the invention can be found.
Durch die Ausbildung der Rastkulisse und der Längsnut an der Innenwand des Gehäuses sowie des Führungsstiftes als Teil des Ringelementes wird kein zusätzlicher Raum gegenüber einer Drucktaste, die ausschließlich mit Rastfunktion oder mit Tastfunktion ausgestattet ist, beansprucht. Das offene Ringelement ist geeignet, bei der Montage leicht in eine entsprechende ringförmige Nut am Schaltstößel aufgerastet und dort anschließend leicht verschieblich gelagert zu werden. Durch die Zutrittsöffnung kann der nach außen weisende Führungsstift mit einem geeigneten spitzen Werkzeug leicht im oder gegen den Uhrzeigersinn verschoben werden, wobei die jeweilige Endstellung des durch die Zutrittsöffnung gut sichtbaren Führungsstiftes die Funktionsart der Drucktaste eindeutig zu erkennen gibt. Eine die Rastkulisse und die Längsnut annähernd auf halber Höhe verbindende Querverbindung ermöglicht nur in halb gedrückter Stellung der Drucktaste ein bewusstes Umstellen des Führungsstiftes, wogegen in den beiden Endstellungen ein gewolltes oder durch Schwingungen oder Erschütterungen bewirktes unbeabsichtigtes Verstellen ausgeschlossen ist. Zweckmäßigerweise ist die Querverbindung gleichzeitig als Zutrittsöffnung ausgebildet.Due to the design of the detent gate and the longitudinal groove on the inner wall of the housing and the guide pin as part of the ring member no additional space compared to a push button, which is equipped exclusively with locking function or tactile function claimed. The open ring element is suitable, easily latched during assembly in a corresponding annular groove on the switch plunger and then stored there easily displaced. Through the access opening, the outwardly facing guide pin can be easily moved clockwise or counterclockwise with a suitable pointed tool, with the respective end position of the guide pin, which is clearly visible through the access opening, clearly indicating the type of function of the pushbutton. A connecting link and the longitudinal groove approximately at half height connecting cross-connection allows only in half depressed position of the pushbutton deliberate changeover of the guide pin, whereas in the two end positions a deliberate or caused by vibrations or shocks unintentional adjustment is excluded. Conveniently, the cross-connection is simultaneously formed as an access opening.
Eine zweckmäßige Weiterbildung besteht in der frontseitig auslaufenden Ausbildung der Rastkulisse und/oder der Längsnut, um beim Zusammenbau der Drucktasten den Führungsstift einen leichten Eintritt in die Rastkulisse bzw. die Längsnut zu verschaffen. Eine gegenüberliegende Anordnung der für die Rast- und Tastfunktion zuständigen Führungselemente dient der zuverlässigen Arbeitsweise der Drucktaste.An expedient development consists in the front side expiring training of the detent gate and / or the longitudinal groove to the guide pin to gain easy access to the detent gate or the longitudinal groove during assembly of the push buttons. An opposite arrangement of the responsible for the locking and sensing function guide elements is the reliable operation of the push button.

Die Drucktaste 2 für Rast- und Tastfunktion besteht im wesentlichen aus einem hohlzylindrischen Gehäuse 4 und einem darin längsverschieblich und unverdrehbar geführten Schaltstößel 6. Der Schaltstößel 6 ist frontseitig mit einem Betätigungselement 8 versehen, das rückseitig von einer nicht dargestellten Leuchtquelle erhellt werden kann. Durch eine ebenfalls nicht gezeigte schraubenförmige Druckfeder, die um den unteren Teil 10 des Schaltstößels 6 gelegt ist und die sich zwischen einer nach hinten weisenden Ringfläche 12 am mittleren Teil des Schaltstößels 6 sowie einer nach vorn weisenden Teilringfläche 14 des Gehäuses 4 abstützt, wird der Schaltstößel 6 nach vorn, d.h. entgegen der Betätigungsrichtung 16, beaufschlagt. Beim Einfügen des Schaltstößels 6 in das Gehäuse 4 werden die beiden radial abstehenden, elastischen Stößelenden 18 hinter die rückseitigen Anschlagflächen 20 des Gehäuse 4 gerastet und sorgen danach im Zusammenwirken mit der Druckfeder für die Einnahme der Ruheposition der Drucktaste 2. Mit der Bezugsziffer 22 ist ein Außengewinde bezeichnet, auf das eine Montagemutter von hinten auf das Gehäuse 4 geschraubt werden kann. Der Schaltstößel 6 wird im Gehäuse 4 durch einen aufschnappbaren Frontring 23 gehalten.The push-
Die im wesentlichen zylindrische Innenwand 24 des Gehäuses 4 ist mit zwei diametral gegenüber liegenden Einformungen 26 versehen, von denen in Fig. 2 und Fig. 3 nur die hintere zu sehen ist. Jede dieser Einformungen 26 besteht aus einer annähernd herzförmigen Rastkulisse 28, einer parallel zu dieser und in Betätigungsrichtung 16 verlaufenden Längsnut 30 sowie einer die Rastkulisse 28 und die Längsnut 30 annähernd in ihrer mittleren Höhe verbindenden Querverbindung 32. Die Rastkulisse 28 umläuft eine annähernd umgekehrt herzförmige Insel 34. Die Rastkulisse 28 und die Längsnut 30 laufen zur Frontseite hin in eine innere Ausrundung 36 des Gehäuses 4 aus und sind unterhalb dieser Stelle durch einen zungenförmigen Steg 38 getrennt. In einer Ringnut 40 im mittleren Teil des Schaltstößels 6 ist ein offenes Ringelement 42 gelagert, so dass es leichtgängig verdreht werden kann. An dem Ringelement 42 sind zwei diametral gegenüber liegende Führungsstifte 44 ausgebildet, von denen in Fig. 1 und Fig. 2 nur der vordere zu sehen ist. Beim Betätigen der Drucktaste 2 gleiten die Führungsstifte 44 entweder innerhalb der Rastkulissen 28 oder innerhalb der Längsnute 30 entlang. Im ersten Fall funktioniert die Drucktaste 2 rastend, wobei in der gedrückten Stellung der jeweilige Führungsstift 44 unterhalb der umgekehrt herzförmigen Insel 34 rastet. Im zweiten Fall funktioniert die Drucktaste 2 tastend. Wenigstens auf einer Seite ist der Führungsstift 44 durch eine im Gehäuse 4 eingelassene Zutrittsöffnung 46 bei halb gedrücktem Schaltstößel 6 sichtbar, wie in Fig. 1 zu erkennen ist. In dieser halb gedrückten Stellung der Drucktaste 2 kann der Führungsstift 44 mit Hilfe eines durch die Zutrittsöffnung 46 greifenden geeigneten Werkzeuges in oder entgegen dem Uhrzeigersinn verschoben werden. Dabei gleiten die Führungsstifte 44 entlang der Querverbindung 32, um aus der Rastkulisse 28 in die Längsnut 30 oder umgekehrt zu gelangen. Bei der Querverbindung 32 entfällt durch die Ausbildung der Zutrittsöffnung 46 an derselben Stelle die Rückwand.The substantially cylindrical
