Description

Staubsaugervacuum cleaner
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, with an on / off switch and potentiometer arranged in its housing, which components can be actuated by means of an actuating device provided on the outside of the housing.
Ein solcher Satubsauger 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. In this vacuum cleaner, an actuation button for the on / off switch and a rotary knob for adjusting a potentiometer are arranged on the housing.
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 to develop a vacuum cleaner of the type described above so that the cost of 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/Ausschal- ters und durch die drehbewegliche Verstellung des Betätigungsknopfes eine Betätigung des als Drehpotentiometer ausgebildeten Potentiometers erfolgt. 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 Anord- nung der Bedienelemente.The solution to the problem is achieved according to the invention in that the on / off switch and the potentiometer is assigned a common actuation button, which is axially and rotatably arranged on the housing of the vacuum cleaner, with the axially movable adjustment of the actuation button an actuation of the on / off - Ters and by the rotatable adjustment of the actuating button, the potentiometer designed as a rotary potentiometer is actuated. This means that only one actuating element is required to switch the fan motor on and off and to set the speed. This saves both material costs and assembly costs. In addition, there is a space saving with regard to the arrangement of the operating elements.
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 eliminated by the fact that an actuating lever which is under the action of a spring tension and can be pivoted in one end region is provided, which in its other end region is operatively connected to the actuation key of the on / off switch designed as a pushbutton switch can be brought and that the point of action of the actuating button on the actuating lever lies between its two end regions. Dimensional tolerances that occur on the control button or when it is placed on the vacuum cleaner housing are indicated by balanced the operating lever and thus do not have any effect when the on / off switch is operated.
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 actuation button is unnecessary in that the spring tension acting on the actuation lever serves as an axial restoring force for the actuation button. The actuating lever itself can be designed as a resilient lever, 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.The coupling of the actuation button with the rotary potentiometer is achieved in a simple manner in that an axially projecting adjusting shaft is provided on the actuation button, which is coupled to the rotary potentiometer in an axially movable but rotationally fixed manner.
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.A securing of the rotary potentiometer in its respective position is achieved in that the adjusting shaft is passed through a bore of the actuating lever to the rotary potentiometer arranged below the actuating lever and a raster is formed on the actuating lever on the side facing the actuating button, concentrically with the bore, with a counter-detent formed on the end surface of the actuating button resting on the actuating lever cooperates.
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 is limited by a stop member. 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 path limitation is achieved in a structurally simple manner in that a radially outwardly projecting rib is provided on the shaft of the actuating button and a stop projecting into the rotation path of the rib is provided on the housing of the vacuum cleaner.
Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird die Erfindung nachfolgend noch näher erläutert.Based on an embodiment shown in the drawing, the invention is explained in more detail below.

FIG 2 den Betätigungsknopf nach Fig. 1 im in ein Staubsaugergehäuse einge- bauten Zustand.2 shows the actuation button according to FIG. 1 in a vacuum cleaner housing. built condition.
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, the actuating button 1 is inserted into a tubular recess 3 provided on a vacuum cleaner housing 4. In the lower region of the shaft 2, a locking plate 5 is attached to the shaft, which, when the actuating button 1 is inserted into the vacuum cleaner housing 4, locks behind a locking tongue 6 protruding from the side wall of the tubular recess 3.
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 a through-opening 7 provided in the relevant wall of the vacuum cleaner housing 4. The shaft 2 is essentially formed by four shaft ribs 8 arranged in a cross shape. A shaft rib 8a extends further radially outwards compared to the remaining shaft ribs 8. This shaft rib 8a thus strikes a stop cam 9 projecting radially inward into the through-opening 7 when the actuating button 1 is rotated. This stop cam 9 limits the rotary movement of the actuating button 1 to below 360 °.
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 femer ein Betätigungshebel 13 angeformt, der mit seinem einen Ende 14 verschwenk- bar mit dem Körper des Kunststoffhalteteiles 12 verbunden ist. Das andere Ende 15 des Betätigungshebels 13 ragt frei über die Betätigungstaste 16 des Tastschalters 10.In the vacuum cleaner housing 4, a support plate is installed, on which an on / off switch designed as a pushbutton switch 10 and a rotary potentiometer 11 are arranged. The key switch 10 and the rotary potentiometer 11 are fitted into a plastic holding part 12, which in turn is clipped onto the support plate in a suitable manner. An actuating lever 13 is also formed on the plastic holding part 12 and is pivotally connected at one end 14 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 key 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 Schaf- tes 2 erstreckende und mit dem Schaft 2 verbundene Verstellwelle 18 hindurchgesteckt ist. Mit ihrem freien Ende 19 greift die Verstellwelie 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 actuating lever 13 there is a bore 17 through which an adjusting shaft 18, which extends in the axial extension of the shaft 2 and is connected to the shaft 2, is inserted. With its free end 19, the adjustment shaft 18 extends through a coupling opening of the rotary potentiometer 11. Such a coupling opening is designed in a slot-like manner or as a round opening provided with a flattened side. The adjusting shaft 18 has at its free end 19 a cross-sectional profile corresponding to the shape of the coupling opening. The free end 19 of the adjusting shaft 18 can thus be inserted into the coupling opening. The adjusting shaft 18 can face each other in the axial direction the coupling opening are moved. In contrast, there is a fixed coupling in the direction of rotation, so that when the actuating button 1 is turned, 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 Rastteller 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 is already somewhat depressed when the actuating button 1 is plugged into the vacuum cleaner housing 4. As a result, a counterforce is exerted on the actuating button 1, by means of which the locking plate 5 formed on the shaft 2 is held in contact with the locking tongue 6. The actuating button 1 is thus secured on the vacuum cleaner housing 4. In the direction of rotation, the actuating button 1 is provided with a corresponding guide by a collar 20 provided on it and engaging in the tubular recess 3.
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, a raster 21 consisting of individual locking ribs concentrically surrounding the bore 17 is 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-locking. Due to the spring pressure of the pretensioned actuating lever 13, the locking ribs of the catch 21 are constantly in engagement with the locking strips 22 of the shaft ribs 8, as a result of which the actuating button 1 and thus the rotary potentiometer 11 are fixed in their respective positions.
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 starting up or putting the vacuum cleaner out of operation, the operating button 1 is depressed in each case. The other end 15 of the operating lever 13 hits the operating button 16 of the key switch 10 and presses it down. As a result, the key switch 10 is switched on or off. After releasing the actuating button 1, it is returned to its starting position by the spring force of the actuating lever 13, in which the locking plate 5 rests against the locking tongue 6. In the actuation direction, the adjustment path of the actuation button 1 is limited by the impact of the locking plate 5 on the bottom wall 24 of the tubular recess 3. This also avoids excessive and therefore harmful impact forces on the actuating lever 13 or on the pushbutton switch 10.
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 federnder Hebel ausgebildet ist. If the spring force of the actuating lever 13 is not sufficient to reset the actuating button 1, an additional spring can be provided. Such an additional spring is also used when the operating lever 13 is not designed as a resilient lever from the outset.
