Description

Die Erfindung betrifft einen Staubsauger, mit in dessen Gehäuse angeordnetem Ein/Ausschalter und Potentiometer, welche Bauteile mittels an der Außenseite des Gehäuses vorgesehener Betätigungseinrichtung betätigbar sind.The invention relates to a vacuum cleaner, arranged in its housing On / off switch and potentiometer, which components by means of the outside of the Housing provided actuator are actuated.

Ein solcher Staubsauger ist durch das DE-U-80 20 858 bekannt. Bei diesem Staubsauger ist am Gehäuse eine Betätigungstaste für den Ein/Ausschalter und ein Drehknopf für die Verstellung eines Potentiometers angeordnet.Such a vacuum cleaner is known from DE-U-80 20 858. With this vacuum cleaner there is an actuation button for the on / off switch and a rotary knob on the housing arranged for the adjustment of a potentiometer.

Der Erfindung liegt die Aufgabe zugrunde, einen Staubsauger der eingangs beschriebenen Art so weiterzubilden, daß der Aufwand an Bauteilen reduziert werden kann.The invention has for its object a vacuum cleaner of the type described Art in such a way that the expenditure on components can be reduced.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß dem Ein/Ausschalter und dem Potentiometer ein gemeinsamer Betätigungsknopf zugeordnet ist, der axial- und drehbeweglich am Gehäuse des Staubsaugers angeordnet ist, wobei durch die axialbewegliche Verstellung des Betätigungsknopfes eine Betätigung des Ein/Ausschalters und durch die drehbewegliche Verstellung des Betätigungsknopfes eine Betätigung des als Drehpotentiometer ausgebildeten Potentiometers erfolgt.The object is achieved according to the invention in that the On / off switch and the potentiometer is assigned a common actuation button, which is arranged axially and rotatably on the housing of the vacuum cleaner, whereby the axially movable adjustment of the operating button an operation of the on / off switch and by the rotatable adjustment of the operating button an operation of the trained as a potentiometer potentiometer.

Somit wird für das Ein- und Ausschalten sowie die Drehzahleinstellung des Gebläsemotors nur noch ein Betätigungselement benötigt. Hierdurch wird sowohl eine Einsparung an Materialkosten als auch an Montagekosten erzielt. Außerdem ergibt sich eine Platzeinsparung hinsichtlich der Anordnung der Bedienelemente.Thus for the in and Switching off and the speed setting of the blower motor only one actuating element needed. This will save both material costs and Assembly costs achieved. There is also a space saving in terms of arrangement of the controls.

Der Einfluß von Maßtoleranzen auf die Betätigung des Ein/Ausschalters wird dadurch ausgeschaltet, daß ein unter der Wirkung einer Federspannung stehender, in seinem einen Endbereich verschwenkbarer Betätigungshebel vorgesehen ist, der in seinem anderen Endbereich in Wirkverbindung mit der Betätigungstaste des als Tastschalter ausgebildeten Ein/Ausschalters bringbar ist und daß die Einwirkstelle des Betätigungsknopfes auf den Betätigungshebel zwischen dessen beiden Endbereichen liegt. Auftretende Maßtoleranzen am Betätigungsknopf bzw. bei dessen Plazierung am Staubsaugergehäuse werden durch den Betätigungshebel ausgeglichen und wirken sich somit nicht beim Betätigen des Ein/Ausschalters aus.The influence of dimensional tolerances on the actuation of the on / off switch is thereby switched off that one under the action of a spring tension, in his one End region pivotable actuating lever is provided, which is in its other End area in operative connection with the actuation button of the button switch On / off switch can be brought and that the point of action of the actuating button on the Actuating lever lies between its two end areas. Dimensional tolerances that occur on the control button or when it is placed on the vacuum cleaner housing the actuating lever balanced and thus do not affect the actuation of the On / off switch off.

Eine gesonderte Rückstellfeder für den Betätigungsknopf erübrigt sich dadurch, daß die auf den Betätigungshebel wirkende Federspannung als axiale Rückstellkraft für den Betätigungsknopf dient. Dabei kann der Betätigungshebel selbst als federnder Hebel ausgebildet sein, so daß kein gesondertes Federelement erforderlich ist.A separate return spring for the actuating button is unnecessary in that the spring tension acting on the operating lever as an axial restoring force for the Actuation button serves. The actuating lever itself can act as a resilient lever be designed so that no separate spring element is required.

Die Koppelung des Betätigungsknopfes mit dem Drehpotentiometer gelingt in einfacher Weise dadurch, daß an dem Betätigungsknopf eine axial vorspringende Verstellwelle vorgesehen ist, die axial beweglich jedoch drehfest mit dem Drehpotentiometer gekoppelt ist.Coupling the control button with the rotary potentiometer is easier Way in that an axially projecting adjusting shaft on the actuating button is provided, which is axially movable but non-rotatably coupled to the rotary potentiometer is.

Eine Sicherung des Drehpotentiometers in seiner jeweiligen Stellung wird dadurch erreicht, daß die Verstellwelle durch eine Bohrung des Betätigungshebels zu dem unterhalb des Betätigungshebels angeordneten Drehpotentiometer hindurchgeführt ist und an dem Betätigungshebel auf der dem Betätigungsknopf zugewandten Seite konzentrisch zu der Bohrung eine Rasterung ausgebildet ist, die mit einer an der am Betätigungshebel anliegenden Endfläche des Betätigungsknopfes ausgebildeten Gegenrastung zusammen wirkt.The rotary potentiometer is secured in its respective position by that the adjusting shaft through a hole in the actuating lever to the below the Actuating lever arranged rotary potentiometer is passed and on the Operating lever on the side facing the operating button concentric with the Bore a raster is formed, which with a on the actuating lever End surface of the actuating button trained counter-locking acts together.

Vorteilhaft ist es ferner, daß der Drehweg des Betätigunsknopfes durch ein Anschlagglied begrenzt ist. Damit wird eine Beschädigung des Drehpotentiometers vermieden.It is also advantageous that the path of rotation of the actuating button by a stop member is limited. This prevents damage to the rotary potentiometer.

Eine Drehwegbegrenzung wird auf konstruktiv einfache Weise dadurch erreicht, daß am Schaft des Betätigungsknopfes eine nach radial außen vorspringende Rippe und am Gehäuse des Staubsaugers ein in den Drehweg der Rippe ragender Anschlag vorgesehen ist.A rotation limit is achieved in a structurally simple manner in that A shaft of the actuating button has a rib projecting radially outwards and on the housing of the vacuum cleaner a stop projecting into the rotational path of the rib is provided.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird die Erfindung nachfolgend noch näher erläutert.Based on an embodiment shown in the drawing, the invention explained in more detail below.

1 in the state installed in a vacuum cleaner housing.

Mit 1 ist ein Betätigungsknopf bezeichnet, an dem ein Schaft 2 angeformt ist. Mit dem Schaft 2 ist der Betätigungsknopf 1 in eine an einem Staubsaugergehäuse 4 vorgesehene röhrenförmige Vertiefung 3 eingesetzt. Im unteren Bereich des Schaftes 2 ist ein Rastteller 5 an dem Schaft angebracht, der im in das Staubsaugergehäuse 4 eingesetzten Zustand des Betätigungsknopfes 1 hinter einer aus der Seitenwand der röhrenförmigen Vertiefung 3 vorstehenden Rastzunge 6 verrastet.1 with an actuation button is designated, on which a shaft 2 is integrally formed. With the Shaft 2 is the operating button 1 in a provided on a vacuum cleaner housing 4 tubular recess 3 used. In the lower area of the shaft 2 is a Locking plate 5 attached to the shaft, which is inserted into the vacuum cleaner housing 4 State of the operating button 1 behind one from the side wall of the tubular Recess 3 protruding locking tongue 6 locked.

Unterhalb des Rasttellers 5 tritt der etwas verjüngte Schaft 2 durch eine in der betreffenden Wand des Staubsaugergehäuses 4 vorgesehene Durchstecköffnung 7. Der Schaft 2 wird im wesentlichen durch vier in Kreuzform angeordnete Schaftrippen 8 gebildet. Eine Schaftrippe 8a erstreckt sich gegenüber den restlichen Schaftrippen 8 weiter nach radial außen. Damit trifft diese Schaftrippe 8a beim Verdrehen des Betätigungsknopfes 1 auf einen nach radial innen in die Durchstecköffnung 7 ragenden Anschlagnocken 9. Durch diesen Anschlagnocken 9 wird die Drehbewegung des Betätigungsknopfes 1 auf unter 360° begrenzt.Below the locking plate 5, the somewhat tapered shaft 2 passes through one in the concerned Wall of the vacuum cleaner housing 4 provided through opening 7. The shaft 2 is essentially formed by four shaft ribs 8 arranged in a cross shape. A Shaft rib 8a extends further radially compared to the remaining shaft ribs 8 Outside. Thus, this shaft rib 8a strikes when the operating button 1 is turned a stop cam 9 projecting radially inward into the through opening 7 this stop cam 9, the rotary movement of the operating button 1 is below 360 ° limited.

Im Staubsaugergehäuse 4 ist eine Tragplatine eingebaut, auf der ein als Tastschalter 10 ausgebildeter Ein/Ausschalter und ein Drehpotentiometer 11 angeordnet sind. Der Tastschalter 10 und das Drehpotentiometer 11 sind in ein Kunststoffhalteteil 12 eingepaßt, das seinerseits in geeigneter Weise an die Tragplatine angeklippt ist. An dem Kunststoffhalteteil 12 ist ferner ein Betätigungshebel 13 angeformt, der mit seinem einen Ende 14 verschwenkbar mit dem Körper des Kunststoffhalteteiles 12 verbunden ist. Das andere Ende 15 des Betätigungshebels 13 ragt frei über die Betätigungstaste 16 des Tastschalters 10.A support plate is installed in the vacuum cleaner housing 4, on which a pushbutton 10 trained on / off switch and a rotary potentiometer 11 are arranged. The push button 10 and the rotary potentiometer 11 are fitted in a plastic holding part 12, the in turn is clipped onto the support plate in a suitable manner. On the plastic holding part 12 is also formed an actuating lever 13 which is pivotable at one end 14 is connected to the body of the plastic holding part 12. The other end 15 of the Actuation lever 13 projects freely over the actuation key 16 of the pushbutton switch 10.

Etwa in der Mitte zwischen den beiden Enden 14 und 15 des Betätigungshebels 13 ist an diesem eine Bohrung 17 vorgesehen, durch die eine sich in axialer Verlängerung des Schaftes 2 erstreckende und mit dem Schaft 2 verbundene Verstellwelle 18 hindurchgesteckt ist. Mit ihrem freien Ende 19 greift die Verstellwelle 18 durch eine Ankoppelöffnung des Drehpotentiometers 11 hindurch. Eine solche Ankoppelöffnung ist in bekannter Weise schlitzförmig oder als mit einer abgeflachten Seite versehene Rundöffnung ausgebildet. Die Verstellwelle 18 weist an ihrem freien Ende 19 ein der Form der Ankoppelöffnung entsprechendes Querschittsprofil auf. Damit kann die Verstellwelle 18 mit ihrem freien Ende 19 in die Ankoppelöffnung eingeführt werden. In axialer Richtung kann die Verstellwelle 18 gegenüber der Ankoppelöffnung bewegt werden. In Drehrichtung besteht dagegen eine feste Koppelung, so daß beim Verdrehen des Betätigungsknopfes 1 das Drehpotentiometer 11 verstellt wird.Approximately in the middle between the two ends 14 and 15 of the operating lever 13 is on this a bore 17 is provided through which one is in the axial extension of the shaft 2 extending and connected to the shaft 2 adjustment shaft 18 is inserted. With its free end 19, the adjusting shaft 18 engages through a coupling opening of the rotary potentiometer 11 through. Such a coupling opening is slit-shaped in a known manner or designed as a round opening provided with a flattened side. The adjustment shaft 18 has at its free end 19 a shape corresponding to the coupling opening Cross-sectional profile. The free end 19 of the adjusting shaft 18 can thus enter the coupling opening be introduced. The adjusting shaft 18 can face each other in the axial direction the coupling opening are moved. In contrast, there is a fixed one in the direction of rotation Coupling, so that when turning the operating button 1, the rotary potentiometer 11 is adjusted.

Der Betätigungshebel 13 ist derart an dem Kunststoffhalteteil 12 angeformt, daß er bereits beim Anstecken des Betätigungsknopfes 1 an das Staubsaugergehäuse 4 etwas niedergedrückt wird. Hierdurch wird eine Gegenkraft auf den Betätigungsknopf 1 ausgeübt, durch die der am Schaft 2 angeformte Rasttelter 5 in Anlage an der Rastzunge 6 gehalten wird. Damit ist der Betätigungsknopf 1 am Staubsaugergehäuse 4 gesichert. In Drehrichtung erhält der Betätigungsknopf 1 durch einen an ihm vorgesehenen und in die röhrenförmige Vertiefung 3 eingreifenden Bund 20 eine entsprechende Führung.The actuating lever 13 is molded onto the plastic holding part 12 such that it already when the operating button 1 is plugged into the vacuum cleaner housing 4 something is depressed. As a result, a counterforce is exerted on the operating button 1 exercised, through which the molded on the shaft 2 locking device 5 in contact with the locking tongue 6 is held. The actuating button 1 is thus secured on the vacuum cleaner housing 4. In Direction of rotation receives the operating button 1 by a provided on it and in the tubular recess 3 engaging collar 20 a corresponding guide.

Auf der dem Schaft 2 zugewandten Seite des Betätigungshebels 13 ist eine die Bohrung 17 konzentrisch umgebende, aus einzelnen Rastrippen bestehende Rasterung 21 vorgesehen. In diese Rasterung 21 greifen an den freien Enden 22 der Schaftrippen 8 ausgebildete Rastleisten 23 ein, die somit die Gegenrastung bilden. Durch den Federdruck des vorgespannten Betätigungshebel 13 stehen die Rastrippen der Rasterung 21 ständig in Eingriff mit den Rastleisten 22 der Schaftrippen 8, wodurch eine entsprechende Fixierung des Betätigungsknopfes 1 und damit des Drehpotentiometers 11 in seiner jeweiligen Stellung erreicht wird.On the side of the actuating lever 13 facing the shaft 2 there is a bore 17 concentrically surrounding, consisting of individual locking ribs 21 provided. In this grid 21 engage at the free ends 22 of the shaft ribs 8 formed locking strips 23, which thus form the counter detent. By the spring pressure of the preloaded Operating lever 13, the locking ribs of the grid 21 are constantly engaged with the locking bars 22 of the shaft ribs 8, whereby a corresponding fixation of the actuating button 1 and thus the rotary potentiometer 11 is reached in its respective position.

Beim Inbetriebsetzen bzw. beim Außerbetriebsetzen des Staubsaugers wird der Betätigungsknopf 1 jeweils niedergedrückt. Dabei trifft das andere Ende 15 des Betätigungshebels 13 auf die Betätigungstaste 16 des Tastschalters 10 und drückt diese nieder. Hierdurch wird der Tastschalter 10 ein- oder ausgeschaltet. Nach Loslassen des Betätigungsknopfes 1 wird dieser durch die Federkraft des Betätigungshebels 13 wieder in seine Ausgangsstellung, in der der Rastteller 5 wieder an der Rastzunge 6 anliegt, zurückgestellt. In Betätigungsrichtung wird der Verstellweg des Betätigungsknopfes 1 durch das Auftreffen des Rasttellers 5 auf die Bodenwand 24 der röhrenförmigen Vertiefung 3 begrenzt. Hierdurch werden auch zu hohe und damit schädliche Stoßkräfte auf den Betätigungshebel 13 bzw. auf den Tastschalter 10 vermieden.When the vacuum cleaner is started up or shut down, the actuation button is activated 1 depressed each time. The other end 15 of the actuating lever 13 hits the actuation key 16 of the key switch 10 and depresses it. This will Key switch 10 on or off. After releasing the control button 1, it becomes by the spring force of the actuating lever 13 back to its initial position in which Rest plate 5 rests on the locking tongue 6, reset. In the direction of actuation Adjustment path of the operating button 1 by the impact of the locking plate 5 on the bottom wall 24 of the tubular recess 3 limited. This will also make it too high and therefore Harmful impact forces on the operating lever 13 or on the key switch 10 avoided.

Sollte die Federkraft des Betätigungshebel 13 für die Rückstellung des Betätigungsknopfes 1 nicht ausreichen, kann eine zusätzliche Feder vorgesehen werden. Eine solche zusätzliche Feder wird auch dann eingesetzt, wenn der Betätigungshebel 13 von vornherein nicht als fedemder Hebel ausgebildet ist.If the spring force of the actuating lever 13 for resetting the actuating button 1 an additional spring can be provided. Such an additional Spring is also used when the operating lever 13 is not as from the outset spring lever is formed.
