Abstract
Description
Die Erfindung betrifft ein Gehäuse aus Gehäuse-Oberteil und Gehäuse-Unterteil, bei dem im Gehäuse-Unterteil Tastschalter angeordnet sind, die mittels im Gehäuse-Oberteil gelagerter Tastenknöpfe betätigbar sind, und bei dem im Gehäuse-Unterteil Beleuchtungseinrichtungen pro Tastschalter zur Beleuchtung der zugeordneten Tastenknöpfe vorgesehen sind.The invention relates to a housing of the upper housing part and lower housing part, in which the lower housing part Tastschalter are arranged, which are actuated by means stored in the housing upper part key buttons, and in the lower housing lighting devices per key switch to illuminate the associated key buttons are provided.
Derartige Gehäuse sind für die verschiedensten Anwendungsfälle eingesetzt. Dabei ist der Einbau der Tastschalter und die Zuordnung der Betätigungselemente schon auf die verschiedenste Weise gelöst worden. Sollen die Tastenknöpfe zusätzlich beleuchtet werden können, dann ergeben sich für den Einbau weit größere Schwierigkeiten, da in der Regel die Beleuchtungseinrichtungen seitlich zur Betätigungsachse des Tastenknopfes versetzt sind. Dies bringt keine gleichmäßige Ausleuchtung des Tastenknopfes. Nimmt der Tastenknopf die Beleuchtungseinrichtung auf, dann ist die Kopplung desselben zum Tastschalter aufwändig und kompliziert.Such housings are used for a variety of applications. The installation of the key switch and the assignment of the actuators has already been solved in a variety of ways. If the key buttons can be additionally illuminated, then arise for the installation far greater difficulties, as a rule, the lighting devices are offset laterally to the operating axis of the key top. This does not bring uniform illumination of the button button. Takes the key button the lighting device, then the coupling of the same to the push-button switch is complicated and complicated.
Es ist daher Aufgabe der Erfindung, bei einem Gehäuse der eingangs erwähnten Art die Tastenknöpfe gleichmäßig auszuleuchten und dennoch die Kopplung der Tastenknöpfe mit den zugeordneten Tastschaltern mit einfachen Mitteln betriebssicher auszulegen.It is therefore an object of the invention to evenly illuminate the key buttons in a housing of the type mentioned and yet interpret the coupling of the key buttons with the associated key switches with simple means reliable.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass die hutförmigen Tastenknöpfe mittels ringförmiger Betätigungselemente unverlierbar in Ausnehmungen des Gehäuse-Oberteils gehalten sind, dass die Betätigungselemente mit der Innenseite des Gehäuse-Oberteils verbindbar sind, dass im Gehäuse-Unterteil pro Tastschalter eine Fassung mit Beleuchtungslampe angeordnet ist, die auf die Mitten des zugeordneten Tastenknopfes und des zugeordneten Betätigungselementes ausgerichtet ist, und dass das Betätigungselement die zugeordnete Fassung mit Verstellspiel umschließt und den außerhalb der Fassung angeordneten, zugeordneten Tastschalter schaltet, wenn der zugeordnete Tastenknopf betätigt und das zugeordnete Betätigungselement verstellt wird.This object is achieved according to the invention in that the hat-shaped button buttons are held by means of annular actuators captive in recesses of the housing shell that the actuators are connected to the inside of the housing shell that in the housing base per key switch a version with illumination lamp is arranged, which is aligned with the centers of the associated key button and the associated actuator, and that the actuator surrounds the associated version with Verstellspiel and arranged outside the socket, associated key switch, when the associated key button is pressed and the associated actuator is adjusted.
Bei dieser Ausgestaltung kann die Beleuchtungseinrichtung zentrisch zum Tastenknopf im Gehäuse-Unterteil befestigt werden, so dass sie den Tastenknopf gleichmäßig und ohne Schattenbildung ausleuchtet. Das ringförmige Betätigungselement legt nicht nur den Tastenknopf uvnerlierbar im Gehäuse-Oberteil fest, sondern kann mit seiner Bohrung die Fassung mit der Beleuchtungslampe umschließen und daran verstellt werden, um einen unmittelbar an die Fassung angrenzenden Tastschalter zu betätigen.In this embodiment, the lighting device can be mounted centrally to the key button in the lower housing part, so that it illuminates the key button evenly and without shadows. The annular actuator not only sets the key button captive in the housing shell, but can surround with its bore the socket with the illumination lamp and be adjusted to actuate an immediately adjacent to the socket key switch.
Der Halt und die Führung des Tastenknopfes in der Ausnehmung des Gehäuse-Oberteils lässt sich dadurch einfach erreichen, dass der Tastenknopf hohl ausgebildet ist und von dem zugeordneten Betätigungselement mit einem Bund an der Innenseite des Gehäuse-Oberteils anliegend in der Ausgangsstellung gehalten ist.The hold and the leadership of the key button in the recess of the housing upper part can be achieved simply by the fact that the key button is hollow and is held by the associated actuator with a collar on the inside of the housing shell fitting in the starting position.
Ist dabei vorgesehen, dass das Betätigungselement sich nur am Bund des Tastenknopfes abstützt, der vorzugsweise aus lichtdurchlässigem Material besteht, dann kann sich die Beleuchtungslampe durch das Betätigungselement hindurch bis in den Hohlraum des Tastenknopfes erstrecken.It is provided that the actuating element is supported only on the collar of the key button, which preferably consists of translucent material, then the illumination lamp can extend through the actuator through into the cavity of the key top.
Eine weitere vorteilhafte Ausgestaltung ist dadurch gekennzeichnet, dass die Ausnehmung in dem Gehäuse-Oberteil auf der Innenseite angeformte Führungselemente für den Bund des Tastenknopfes aufweist und dass der Tastenknopf im Bereich des Bundes einen abstehenden Ansatz aufweist, der in Anschlägen im Bereich der Ausnehmung geführt ist und den Tastenknopf unverdrehbar hält. Der Tastenknopf ist damit in der Ausnehmung verdrehsicher geführt und kann mit Kennzeichen versehen werden, die auf eine bestimmte Bedienungsrichtung ausgerichtet sind.A further advantageous embodiment is characterized in that the recess in the housing upper part on the inside of molded guide elements for the collar of the button knob has and that the button button in the region of the federal has a protruding approach, which is guided in attacks in the region of the recess and keeps the key button non-rotatable. The key button is thus guided against rotation in the recess and can be provided with marks that are aligned with a particular operating direction.
Die Festlegung der Betätigungselemente in der Nähe der Ausnehmungen des Gehäuse-Oberteils ist so gelöst, dass auf der Innenseite des Gehäuse-Oberteils eine Halterung angeformt ist, in der an dem Betätigungselement angeformte Halteelemente festlegbar sind. Dabei kann zur Reduzierung des Aufwandes zusätzlich vorgesehen sein, dass die Halterung die Halteelemente für die Betätigungselemente mehrerer nebeneinander angeordneter Tastenknöpfe aufnimmt.The determination of the actuating elements in the vicinity of the recesses of the housing upper part is achieved so that on the inside of the housing upper part a holder is formed, in which integrally formed on the actuating element retaining elements can be fixed. It can be additionally provided to reduce the effort that the holder receives the holding elements for the actuators of several juxtaposed buttons buttons.
Die notwendige Verstellbarkeit der Betätigungselemente wird dadurch erreicht, dass die Halteelemente aus einer Befestigungsleiste und daran angeformter Auslenkfedern besteht, wobei die Enden der Auslenkfedern die Betätigungselemente tragen.The necessary adjustability of the actuating elements is achieved in that the holding elements consists of a fastening strip and integrally formed deflection springs, the ends of the deflection springs carrying the actuating elements.
Die weitere Ausbildung sieht vor, dass die Betätigungselemente auf der dem Gehäuse-Unterteil zugekehrten Seite Begrenzungsansätze tragen, die die vertikale Verstellung des Betätigungselementes begrenzen. Damit kann die Schaltstellung des Betätigungselementes definiert und der Tastschalter vor Beschädigungen geschützt werden.The further training provides that the actuators carry on the housing lower side facing the boundary approaches that limit the vertical adjustment of the actuator. Thus, the switching position of the actuating element can be defined and the key switch can be protected from damage.
Die Fassungen mit den vorzugsweise als LED ausgebildeten Beleuchtungslampen sind mit den Tastschaltern auf einer Leiterplatte angeordnet und verdrahtet, die leicht im Gehäuse-Unterteil so eingebaut werden kann, dass die geforderte Ausrichtung erreicht ist. Dabei können die Tastschalter wahlweise als monostabile oder bistabile Schalter ausgelegt sein, wobei die Auslenkfedern der Betätigungselemente als Rückstellfedern für die Tastenknöpfe dienen. Dies insbesondere dann, wenn die ringförmigen Betätigungselemente mit den Auslenkfedern und der Befestigungsleiste aus elastischem Kunststoff als Spritzgussteil hergestellt werden.The sockets with the preferably designed as LED lighting lamps are arranged and wired with the key switches on a circuit board, which can be easily installed in the lower housing part so that the required alignment is achieved. In this case, the key switches can be designed either as a monostable or bistable switch, the deflection springs of the actuators serve as return springs for the key buttons. This is especially true when the annular actuators are made with the deflection springs and the fastening strip made of elastic plastic as an injection molded part.
Für eine eventuelle Nachrüstung weiterer Tastschalter kann nach einer Weiterbildung vorgesehen sein, dass im Gehäuse-Oberteil nicht belegte Ausnehmungen für Tastenknöpfe mittels ausbrechbarer Verschlussplatten abgedeckt sind.For a possible retrofitting of further key switches can be provided according to a development that are not covered in the housing upper part occupied recesses for key buttons by breakable closure plates.
