Description

Die Erfindung betrifft einen Drucktaster mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a push-button with the features of the preamble of claim 1.

Als Stand der Technik sind Drucktaster für Bedienflächen zur Maschinenbedienung (z.B. von Werkzeugmaschinen) bekannt, deren Druckknopf über eine separate Druckfeder bei Nichtbetätigung in eine Ausgangsposition zurückgestellt wird. Dabei stützt sich die Druckfeder zwischen Gehäuse und Druckknopf des Drucktasters ab. Zusätzlich ist eine Schiebe- bzw. Membrandichtung zur Abdichtung des Druckknopfes gegenüber dem Gehäuse vorgesehen. Derartige Drucktaster mit Abdichtungs- und federnder Rückstellfunktion besitzen somit jeweils eine separate Dichtung und eine Rückstellfeder.As state of the art push buttons for control surfaces for Machine operation (for example, of machine tools) known whose Push-button via a separate compression spring when not in operation is returned to a starting position. there the compression spring is supported between housing and push button of the pushbutton. In addition, a sliding or membrane seal for sealing the push button against the housing intended. Such push button with sealing and resilient reset function thus each have a separate Seal and a return spring.

Aus der DE 30 41 470 A1 geht ein Drucktaster, insbesondere zum Einbau in Bedienpulte zur Maschinenbedienung, hervor, wobei in einem Gehäuse ein Druckknopf federnd aufgenommen ist und der Druckknopf und das Gehäuse über ein Dichtelement gegeneinander abgedichtet sind.From DE 30 41 470 A1 is a pushbutton, in particular for installation in control panels for machine operation, in a housing a push button is resiliently received and the push button and the housing via a sealing element against each other are sealed.

In der US-A-5,283,498 wird ein Federelement offenbart, welches Stege mit stärkerer Wanddicke und Zwischenbereiche mit schwächerer Wanddicke aufweist.In US-A-5,283,498 a spring element is disclosed which Bars with thicker walls and intermediate areas having weaker wall thickness.

Der Erfindung liegt die Aufgabe zugrunde, einen Drucktaster anzubieten, bei dem die Rückstellfunktion bei Betätigung zuverlässig gewährleistet ist.The invention is based on the object, a push button in which the reset function is reliable when actuated is guaranteed.

Die Aufgabe der vorliegenden Erfindung wird durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 in Verbindung mit den Merkmalen des Oberbegriffs gelöst. Vorteilhafte Ausführungsformen der Erfindung werden in den Unteransprüchen 2 bis 12 realisiert.The object of the present invention is characterized by the features the characterizing part of claim 1 in conjunction solved with the features of the preamble. advantageous Embodiments of the invention are defined in the subclaims 2 to 12 realized.

Beim erfindungsgemäßen Drucktaster übernimmt das Dichtelement neben seiner Abdichtungsfunktion auch eine Federfunktion und dient zur Rückstellung des betätigten Druckknopfes in eine Ausgangsposition beim Loslassen des Druckknopfes. Damit kann auf das bisher übliche separate Federelement vollständig verzichtet werden. Das verwendete Dichtelement besitzt eine Doppelfunktion, so daß der erfindungsgemäße Drucktaster konstruktiv vereinfacht wird und aus einer geringeren Anzahl von Teilen besteht. When pressure switch according to the invention takes over the sealing element in addition to its sealing function also a spring function and serves to reset the operated push button in one Starting position when releasing the push button. So that can completely dispensed with the previously customary separate spring element become. The sealing element used has a double function, so that the pushbutton according to the invention constructive is simplified and from a smaller number of Sharing exists.

Vorteilhafterweise besitzt das Dichtelement verschiebbare oder einrollbare Endabschnitte, welche bei Betätigung des Druckknopfes in Betätigungsrichtung verschoben, gestaucht und/oder ab-/eingerollt werden. Hierdurch baut sich im Dichtelement eine Spannung auf, die bei Loslassen des Druckknopfes zur federnden Rückstellung des Druckknopfes in eine Ausgangsposition führt.Advantageously, the sealing element has displaceable or retractable end portions, which upon actuation of the Push button shifted in the direction of actuation, compressed and / or rolled off. This builds up in the sealing element a tension on when releasing the push button for resilient provision of the push button in a starting position leads.

Dabei behält das Dichtelement den Dichtkontakt zum Druckknopf und zum Gehäuse des Drucktasters, so daß während des Betätigungsvorgangs des Druckknopfes und der darauffolgenden Rückstellung bei Loslassen des Druckknopfes zu jedem Zeitpunkt eine Abdichtung zwischen Druckknopf und Gehäuse erreicht wird.The sealing element retains the sealing contact to the push button and to the housing of the pushbutton so that during the actuation process the push button and the subsequent reset when releasing the push button at any time achieved a seal between the push button and the housing becomes.

Letzteres wird besonders zuverlässig erreicht, wenn die Endabschnitte des Dichtelements umfassend (insbesondere formschlüssig) in Ausnehmungen des Druckknopfes und/oder von mit dem Druckknopf verbundenen Bauelementen aufgenommen sind.The latter is achieved particularly reliably when the end sections the sealing element comprising (in particular form-fitting) in recesses of the push button and / or with are added to the push button connected components.

Zur Ausbildung einer Rückstellkraft im Dichtelement sind Stege mit verdickter Wandstärke und Zwischenwände mit verminderter Wandstärke vorgesehen. Hierdurch kann beim Betätigen des Druckknopfes und dem Stauchen und/oder Einrollen des Dichtelements ein gezielter Materialfluß der beabstandet zueinander angeordneten Stege erreicht werden, wobei ein gegenseitiger Kontakt der Stege vermieden wird.To form a restoring force in the sealing element are webs with thickened wall thickness and intermediate walls with reduced Wall thickness provided. As a result, when you press the Push button and the upsetting and / or curling of the sealing element a targeted material flow of the spaced apart arranged webs can be achieved, with a mutual Contact of the webs is avoided.

Das Federungsverhalten des Dichtelements wird durch integrierte (vorgebogene) Federelemente, z.B. aus Metall oder Kunststoff, verändert und dosiert.The suspension behavior of the sealing element is integrated (pre-bent) spring elements, e.g. made of metal or Plastic, modified and dosed.

Es werden Stege mit integrierten (z.B. umspritzten) Federelementen verwendet, wodurch eine erhöhte Rückstellkraft und eine besonders robuste Ausführungsform des Dichtelements verwirklicht werden. There are webs with integrated (for example, overmolded) spring elements used, whereby an increased restoring force and a particularly robust embodiment of the sealing element realized become.

Here are the end sections 4 continues to form fit in the recesses 5a and 5b of the recorded, so that the mutual sealing function is maintained.

Im Zustand des betätigten Druckknopfes 2 gemäß FIG 2 baut sich damit im Dichtelement 3 eine Rückstellkraft auf, welche beim Loslassen des Druckknopfes 2 letzteren entgegen der Verschieberichtung 11 in die Ausgangsposition nach FIG 1 zurückbewegt. Damit besitzt das Dichtelement 3 die geschilderte Doppelfunktion eines Dicht- und Federelements.In the state of the operated push button 2 according to FIG 2 builds thus a restoring force in the sealing element 3, which when you release the push button 2 latter counter to the direction of displacement 11 is moved back to the starting position according to FIG. Thus, the sealing element 3 has the described Double function of a sealing and spring element.

Aus der perspektivischen Draufsicht nach FIG 3 geht der im wesentlichen rotationssymmetrische und kuppelartige Aufbau des Innenbereichs 19 des Dichtelements 3 hervor. Dabei wird die Öffnung 7 vom umlaufenden Endabschnitt 4 gebildet. Ferner sind in radialer Richtung (sternförmig) angeordnete Stege 8 abgebildet, in deren Bereich die Wanddicke des Dichtelements 3 verstärkt ist.From the perspective plan view of FIG 3 is the in essential rotationally symmetrical and dome-like structure the inner region 19 of the sealing element 3. It will the opening 7 is formed by the circumferential end section 4. Further are arranged in the radial direction (star-shaped) webs. 8 mapped, in whose area the wall thickness of the sealing element 3 is reinforced.

Zwischen den Stegen 8 befinden sich Zwischenwandbereiche 9 mit verminderter Wandstärke. Beim Betätigen des Druckknopfes 2 können sich die Stege 8 gemäß FIG 2 in Betätigungsrichtung einrollen, wobei durch die beabstandete Anordnung der Stege 8 nach FIG 3 kein gegenseitiges Kontaktieren der Stege 8 erfolgt. Gleichzeitig wird das Einrollen der Stege 8 durch die nachgebenden Zwischenwandbereiche 9 mit verminderter Wand dicke ermöglicht.Between the webs 8 are intermediate wall portions 9th with reduced wall thickness. When pressing the push button 2, the webs 8 according to FIG 2 in the direction of actuation roll, wherein the spaced arrangement of the webs. 8 3, no mutual contacting of the webs 8 takes place. At the same time, the curling of the webs 8 by the yielding partition walls 9 with reduced wall thick allows.

Der Endabschnitt 4 im Bereich der Öffnung 7 des Dichtelements 3 besitzt sowohl im Bereich eines Zwischenwandbereiches 9 als auch im Bereich eines Steges 8 eine an die umlaufende Ausnehmung 5 des Druckknopfes 2 angepaßte Form. Die Endabschnitte 4 gleiten in den Ausnehmungen 5 des Druckknopfes 2 bei dessen Betätigung ab und stellen weiterhin eine Abdichtung zwischen Dichtelement 3 und Druckknopf 2 sicher.The end portion 4 in the region of the opening 7 of the sealing element 3 has both in the area of an intermediate wall area 9 as also in the region of a web 8 a to the circumferential recess 5 of the push button 2 adapted form. The end sections 4 slide in the recesses 5 of the push button 2 at the Actuation and continue to provide a seal between Sealing element 3 and push button 2 safe.

FIG 4 zeigt in einer Schnittdarstellung das Dichtelement 3 mit Dichtungshülse 15 und verstärkter Wanddicke im Bereich eines Stegs 8 und verminderter Wanddicke im Zwischenwandbereich 9. Durch (schematisch gezeichnete) integrierte Federelemente 10, z.B. im Bereich der Stege 8, wird das Federverhalten des Dichtelements 3 verändert und z.B. dessen Rückstellkraft erhöht.4 shows a sectional view of the sealing element. 3 with sealing sleeve 15 and increased wall thickness in the area a web 8 and reduced wall thickness in the intermediate wall area 9.
