Description

Die Erfindung betrifft eine Einbau-Kabeltrommel für einen Staubsauger mit einem Aufwickelsystem für ein Anschlusskabel, umfassend eine Antriebsvorrichtung zum Drehen für die Kabeltrommel, eine Aktiviereinrichtung, über welche die Antriebsvorrichtung in Gang gesetzt oder freigegeben wird, eine Arretiervorrichtung, über welche die Aktiviereinrichtung in dem die Antriebsvorrichtung in Gang setzenden oder freigebenden Zustand gehalten wird, und eine Rücksetzeinrichtung, welche die Arretiervorrichtung und hierüber die Aktiviereinrichtung durch Ziehen des Anschlusskabels in Abwickelrichtung deaktiviert, wobei die Rücksetzeinrichtung über die in Abwickelrichtung gedrehte Kabeltrommel (1) aktivierbar ist, wobei die Kabeltrommel ein Rad antreibt, welches in Wirkverbindung mit einem Schaltnocken zur Deaktivierung der Arretiervorrichtung steht, und wobei die Wirkverbindung bei Drehung der Kabeltrommel in Aufwickelrichtung über einen Freilauf unterbrochen ist.The invention relates to a built-in cable drum for a vacuum cleaner with a winding system for a connection cable, comprising a drive device for rotating the cable drum, an activating device, via which the drive device is set or released, a locking device, via which the activating device in the A reset device, which deactivates the locking device and thereby the activating device by pulling the connecting cable in the unwinding, wherein the reset means on the unwound in the unwinding cable drum (1) is activated, wherein the cable drum drives a wheel which is in operative connection with a switching cam for deactivating the locking device, and wherein the operative connection is interrupted upon rotation of the cable drum in the winding direction via a freewheel.

Eine Einbau-Kabeltrommel ist aus der US-A-2,428,446 bekannt. Dort erfolgt das Betätigen der Arretiervorrichtung und der Rücksetzeinrichtung durch ein Element (washer 46), welches in reibschlüssiger Verbindung mit dem Kabel steht. Hierdurch erfolgt eine hohe Beanspruchung des Kabels, außerdem sind große Anforderungen an die Einhaltung eines exakten Durchmessers gestellt.A built-in cable drum is out of the US-A-2,428,446 known. There, the actuation of the locking device and the reset means by an element (washer 46), which is in frictional connection with the cable. This results in a high stress on the cable, also great demands are placed on compliance with an exact diameter.

Aus der US-A-2,393,138 ist eine Einbau-Kabeltrommel der eingangs genannten Art bekannt. Dort erfolgt die Realisierung des Freilaufs durch eine Anordnung aus Federn und einem Reibelement.From the US-A-2,393,138 a built-in cable drum of the type mentioned is known. There, the realization of the freewheel by an arrangement of springs and a friction element.

Aus dem Stand der Technik sind weiterhin Einholvorrichtungen, die mit einer Einbau-Kabeltrommel für Staubsauger zusammenwirken in unterschiedlichen Ausführungen bekannt. Eine Ausführung offenbart beispielsweise die DE 196 07146 , wobei es sich bei dieser Ausführungsform um eine Bremsanordnung für das Kabel im Einzugsschacht handelt. So besteht hierbei die Bremsanordnung aus einer in einer Kulisse geführten Bremsrolle, die, wenn das Kabel gezogen wird, sich in der Kulisse derart hochschiebt, dass die Bremsrolle das Kabel frei gibt. Bei Zugentlastung zieht sich die Bremsrolle in der Kulisse wieder gegen das Kabel, so dass die Bremsrolle den weiteren Kabeleinzug behindert. Somit ist ein automatischer Aufwickelvorgang, welcher nur eine einmalige Aktion erfordert nicht möglich. Hier muss vielmehr während des gesamten Aufwickelvorgangs das Kabel gehalten werden und demzufolge durch die Hand des Benutzers gleiten. Dies führt zu einer unerwünschten Wärmeentwicklung und zur Verschmutzung der Hand.From the state of the art further Einholvorrichtungen that interact with a built-in cable drum for vacuum cleaner in different versions are known. One embodiment, for example, discloses DE 196 07146 , wherein this embodiment is a brake assembly for the cable in the feed chute. Thus, in this case, the brake assembly consists of a guided in a backdrop brake roller, which, when the cable is pulled up in the scenery so hochschiebt that the brake roller releases the cable. With strain relief, the brake roller in the backdrop pulls against the cable again, so that the brake roller obstructs the further cable entry. Thus, an automatic winding process, which requires only a one-time action is not possible. Here, rather, the cable must be held during the entire winding process and therefore slide through the user's hand. This leads to an undesirable heat development and contamination of the hand.

Eine andere Ausführungsform zeigt die DE 100 50 555 . Diese Ausführungsform einer Einholvorrichtung ist derart ausgestaltet, dass sie eine automatische oder eine halbautomatische Betriebsart zulässt. In der automatischen Betriebsart wird das Anschlusskabel vollständig aufgerollt, indem einmal ein Tastenteil gedrückt wird. Die halbautomatische Betriebsart stellt sich durch permanentes Drücken des Kabeltastteils durch den Benutzer ein. Hierzu verfügt die Einholvorrichtung über eine Sperrklinke, die in Wirkverbindung mit dem Bremshebel steht. Dabei sind Bremshebel und Sperrklinke in einem Fußtaster integriert, so dass wenn beispielsweise Volleinzug gewünscht wird, der als Fußschalter ausgebildete Bremshebel betätigt wird, der insbesondere den Bremshebel derart verriegelt, dass die gespannte Dreh- oder Wickelfeder das Anschlusskabel komplett einzieht. Ist das gesamte Kabel auf der Trommel aufgewickelt, so befindet sich im Bereich des Steckers ein Element, welches die Sperrklinke entriegelt. Somit versteht es sich von selbst, dass, wenn das Kabel komplett eingezogen ist und der Stecker mit dem Entriegelungselement in dem Einzugsschacht der Einholvorrichtung eingelaufen ist, die Sperrklinke, die in Wirkverbindung mit dem Bremshebel steht, entriegelt wird, so dass beim nächsten Auszug des Anschlusskabels die Sperrklinke für die nächste Verriegelung des Bremshebels wieder frei ist.Another embodiment shows the DE 100 50 555 , This embodiment of a collecting device is designed such that it is an automatic or semi-automatic Operating mode permits. In automatic mode, the connection cable is completely rolled up by pressing a button part once. The semi-automatic mode adjusts itself by permanently pressing the cable load part by the user. For this purpose, the Einholvorrichtung has a pawl, which is in operative connection with the brake lever. In this case, the brake lever and pawl are integrated in a footswitch, so that, for example, if a full-load is desired, designed as a foot switch brake lever is actuated, in particular locks the brake lever such that the tensioned rotary or coil spring completely retracts the connection cable. If the entire cable is wound on the drum, then there is an element in the region of the plug, which unlocks the pawl. Thus, it goes without saying that when the cable is completely retracted and the plug with the unlocking element has run in the intake shaft of the retrieving device, the pawl, which is in operative connection with the brake lever, is unlocked, so that the next extract the connection cable the pawl is free again for the next locking of the brake lever.

Ausgehend von dieser zuletzt beschriebenen Art einer Einbau-Kabeltrommel mit einer Einholvorrichtung, die den vollautomatischen Einzug gewährleistet, wird es als nachteilig angesehen, dass konventionelle Stecker am Anschlusskabel nicht oder nur bedingt Verwendung finden, weil insbesondere der Stecker den Entriegelungsvorgang für die Sperrklinke ansteuert. Ein weiterer Nachteil dieser Ausführungsform ist es, dass bei Erschlaffen der Dreh- bzw. Wickelfeder der Volleinzug des Anschlusskabels nicht mehr gewährleistet ist, so dass dann die Freigabe der Sperrklinke nicht mehr vollzogen wird, weil der Stecker nicht mehr bis zum Ende eingezogen wird. Die Taste für die Freigabe des Bremshebels bleibt dann aktiviert nach dem nächsten Ausziehvorgang, so dass beim Loslassen des Kabels die Einholvorrichtung ungewollt das Kabel wieder zurück zieht, ohne dass der Benutzer es wünscht.Based on this last-described type of built-in cable drum with a Einholvorrichtung that ensures the fully automatic feeder, it is considered disadvantageous that conventional connector on the cable not or only limited use, because in particular the plug activates the unlocking process for the pawl. Another disadvantage of this embodiment is that when slackening the turning or winding spring of the complete insertion of the connecting cable is no longer guaranteed, so that then the release of the pawl is no longer completed, because the plug is not retracted to the end. The button for releasing the brake lever remains activated after the next extraction process, so that when you release the cable, the retrieving unintentionally pulls the cable back without the user wants it.

Der Erfindung stellt sich somit das Problem, ein Aufwickelsystem für den vollautomatischen Einzug des Anschlusskabels bereitzustellen, das unabhängig von der Art des verwendeten Kabels bzw. Steckers und seinem Aufwickelzustand ist und bei welchem außerdem eine Beschädigung des Kabels vermieden wird.The invention thus raises the problem of providing a winding system for the fully automatic insertion of the connection cable, which is independent of the type of cable or plug used and its winding state and in which also damage to the cable is avoided.

Erfindungsgemäß wird dieses Problem mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention this problem is solved with the features of claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile bestehen darin, dass die Bewegung des Kabels nur indirekt zum Aktivieren der Rücksetzeinrichtung beiträgt. Es ist somit keinerlei formschlüssiger oder reibschlüssiger Kontakt zwischen dem Kabel und der Arretiervorrichtung oder der Rücksetzeinrichtung notwendig. Der Zug am Kabel wird nur benötigt, um die Kabeltrommel zu drehen und hierüber den Freilauf zu aktivieren.The advantages achievable with the invention are that the movement of the cable only indirectly contributes to the activation of the reset device. There is thus no positive or frictional contact between the cable and the locking device or the reset device necessary. The pull on the cable is only needed to turn the cable drum and to activate the freewheel.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen rein schematisch dargestellt und wird nachfolgend näher beschrieben. Es zeigen:

Figur 2:

Figur 3:

An embodiment of the invention is shown purely schematically in the drawings and will be described in more detail below. Show it:
FIG. 1:
a front view of the built-in cable drum according to the invention;
FIG. 2:
a rear view of the built-in cable drum according to the Fig. 1 ;
FIG. 3:
a partial section of the freewheel device according to the section line A - A in Fig. 1

Die Figur 1 zeigt in der Vorderansicht eine Einbau-Kabeltrommel 1 für einen nicht näher dargestellten Staubsauger mit einem Aufwickelsystem für das Anschlusskabel 2, dessen Stecker in Figur 2 in zwei Lagen 3 und 3' dargestellt ist (vollständig aufgewickelte Lage 3 ohne Einbau der Kabeltrommel 1 im Staubsauger durchgezogen - Einbaulage 3' im Staubsauger gestrichelt). Das Aufwickelsystem umfasst dabei einen Antrieb in Form einer Wickelfeder 4, von der das eine Ende an einem umlaufenden Steg 5 an der drehbaren Kabeltrommel 1 und das andere Ende an der ortsfesten Achse 6 einer Federtrommel 7 befestigt ist, wobei letztere in einem separaten Gehäuse 8 an der Trommelhalterung 9 gelagert ist. Wird nun die Kabeltrommel 1 durch Auszug des Anschlusskabels 2 gedreht, wickelt sich die Feder 4 um den Steg 5 und erfährt somit eine gespannte Lage. In dieser Lage wird die Trommel 1 durch eine später beschriebene Bremseinrichtung gehalten. Nach dem Lösen der Bremseinrichtung wickelt sich die Feder 4 wieder in ihr Gehäuse 8 zurück und treibt dadurch die Trommel 1 in Aufwickelrichtung an, welche in Figur 2 dem Gegenuhrzeigersinn entspricht.The FIG. 1 shows in front view a built-in cable drum 1 for a vacuum cleaner not shown with a winding system for the connecting cable 2, the plug in FIG. 2 in two layers 3 and 3 'is shown (fully wound layer 3 without installation of the cable drum 1 in the vacuum cleaner pulled through - mounting position 3' dashed lines in the vacuum cleaner). The winding system comprises a drive in the form of a coil spring 4, one end of which is fastened to a revolving web 5 on the rotatable cable drum 1 and the other end to the stationary shaft 6 of a spring drum 7, the latter being in a separate housing 8 the drum holder 9 is mounted. If now the cable drum 1 is rotated by extracting the connection cable 2, the spring 4 winds around the web 5 and thus experiences a tensioned position. In this position, the drum 1 is held by a braking device described later. After releasing the braking device, the spring 4 winds back into its housing 8 and thereby drives the drum 1 in the winding, which in FIG. 2 counterclockwise.

Weiter umfasst das Aufwickelsystem eine Bremseinrichtung, bestehend aus einer Kabelbremse, welche über einen Bremshebel 10 gegen die Wirkung einer Rückstellfeder 11 deaktiviert wird, wobei der Bremshebel 10 über eine nicht dargestellte, am Staubsaugergehäuse gelagerte Tipptaste betätigt wird.Further, the winding system comprises a braking device consisting of a cable brake, which is deactivated by a brake lever 10 against the action of a return spring 11, wherein the brake lever 10 is actuated via a not shown, mounted on the vacuum cleaner housing touch button.

Der Bremshebel 10, ebenfalls deutlich zu erkennen in der Figur 1, weist eine L-Form auf, wobei der Schaft 12 des Bremshebels 10 zwischen an der Trommelhalterung 9 angeformten Führungselementen 13 verschiebbar gelagert ist. Endseitig am abgewinkelten Schenkel 14 des Bremshebels 10 ist eine Bremsrolle 15 angeordnet. Die Bremsrolle wird dabei in einer Zwangsführung gehalten, welche aus einer an der Trommelhalterung angeformten Schrägfläche 16 und dem flanschartig verbreiterten Rand 17 der Kabeltrommel 1 selbst besteht. Durch die Kraft der Rückstellfeder 11 wird die Bremsrolle 15 in diese Zwangsführung geklemmt und dabei an den Rand 17 gepresst, so dass sie die Drehbewegung der Trommel 1 verhindert. Durch Drücken des Schafts 12 in Richtung des Pfeils 18 wird die Bremsrolle 15 vom Rand 17 gelöst und hierüber die Wickelfeder 4 aktiviert. Demnach dient der betätigte Bremshebel 10 als Aktiviereinrichtung für die Antriebsvorrichtung der Kabeltrommel 1.The brake lever 10, also clearly visible in the FIG. 1 , Has an L-shape, wherein the shaft 12 of the brake lever 10 is slidably mounted between formed on the drum holder 9 guide elements 13. End of the angled leg 14 of the brake lever 10, a brake roller 15 is arranged. The brake roller is held in a forced operation, which consists of an integrally formed on the drum holder inclined surface 16 and the flange widened edge 17 of the cable drum 1 itself. By the force of the return spring 11, the brake roller 15 is clamped in this forced operation and thereby pressed against the edge 17 so that it prevents the rotational movement of the drum 1. By pressing the shaft 12 in the direction of arrow 18, the brake roller 15 is released from the edge 17 and over this the coil spring 4 is activated. Accordingly, the actuated brake lever 10 serves as an activating device for the drive device of the cable drum 1.

Wie aus der Darstellung der Vorderansicht der Figur 1 zu erkennen ist, wirkt mit dem Bremshebel 10 eine Sperrklinke 19 zusammen, die ebenfalls gegen die Wirkung einer Drehfeder 20 den Bremshebel 10 in der gedrückten Lage, also in der Aktivierstellung für die Antriebsvorrichtung hält.As seen from the front view of the FIG. 1 can be seen, a pawl 19 cooperates with the brake lever 10, which also holds against the action of a torsion spring 20, the brake lever 10 in the depressed position, ie in the activation position for the drive device.

Wie aus dem Verlauf der Sperrklinke 19 zu erkennen ist, nimmt diese eine mehrfach abgewinkelte Form ein. Ein in Richtung des Bremshebels 10 und damit senkrecht zu seiner Betätigungsrichtung (Pfeil 18) zeigender Schenkel 21 der Sperrklinke 19 weist an seinem Ende eine Rastnase 22 auf, die einen kulissenartigen Bereich über den Verschiebeweg des Bremshebels 10 abgreift. Dabei besteht der kulissenartige Bereich einerseits aus einem am Bremshebel angeordneten unteren Verschiebebereich 23, der insbesondere den entriegelten Zustand des Bremshebels bewirkt. Oberhalb des Verschiebebereichs 23 ist eine Abstufung 35 vorgesehen, die für den verriegelten Zustand des Bremshebels 10 verantwortlich ist. Die Sperrklinke 19 ist dabei mit ihrem freien Ende 24 gegen die Vorspannung der bereits oben näher bezeichneten Drehfeder 20 an der Trommelhalterung 9 gelagert. Wird nun bei einmaligem Drücken bzw. bei Tippbetätigung des Schafts 12 dieser in Richtung des Pfeils 18 bewegt, hält ihn die Sperrklinke 19 in dieser Stellung, so dass die Antriebsvorrichtung freigegeben ist.As can be seen from the course of the pawl 19, this assumes a multi-angled shape. A in the direction of the brake lever 10 and thus perpendicular to its operating direction (arrow 18) pointing leg 21 of the pawl 19 has at its end a latching lug 22 which picks up a backdrop-like region over the displacement of the brake lever 10. In this case, there is the backdrop-like region on the one hand from a arranged on the brake lever lower displacement portion 23, which causes in particular the unlocked state of the brake lever. Above the displacement region 23, a gradation 35 is provided, which is responsible for the locked state of the brake lever 10. The pawl 19 is mounted with its free end 24 against the bias of the already described above in more detail torsion spring 20 to the drum holder 9. If it is moved in the direction of the arrow 18 with a single press or by inching of the shaft 12, the pawl 19 keeps him in this position, so that the drive device is released.

Erfindungsgemäß erfolgt bei der Einbau-Kabeltrommel 1 das Rücksetzen der Sperrklinke 19 dadurch, dass durch Zug am Kabel 2 die Trommel 1 in Abwickelrichtung gedreht wird und dabei einen Schaltnocken 25 in Gang setzt, die die Sperrklinke 19 in Richtung des Pfeils 26 drückt und damit den Bremshebel 10 entriegelt. Der Schaltnocken 25 ist an ein Zahnrad 27 angeformt, welches unter Zwischenschaltung eines Freilaufs von der Trommel 1 angetrieben wird. Sie steht in Eingriff mit einer Nase 28, welche an dem in Betätigungsrichtung des Bremshebels 10 gerichteten Schenkel 21 der Sperrklinke 19 angeformt ist.According to the invention, in the built-in cable drum 1, the reset of the pawl 19 is characterized in that by train on the cable 2, the drum 1 is rotated in the unwinding while a switching cam 25 in motion that presses the pawl 19 in the direction of arrow 26 and thus the Brake lever 10 unlocked. The switching cam 25 is formed on a gear 27, which is driven with the interposition of a freewheel of the drum 1. It is engaged with a nose 28 which is formed on the direction of actuation of the brake lever 10 directed leg 21 of the pawl 19.

Die Figur 2 zeigt insbesondere die Rückansicht der Einbau-Kabeitrommel 1. Wie aus der Zusammenschau der Figur 2 und der Figur 3 erkenntlich ist, stellt der Freilauf als Hülsenfreilauf 29 die kraftschlüssige Verbindung zwischen den Achsen 31 und 33 eines antriebsseitigen Zahnrads 30 und eines abtriebsseitigen Zahnrads 32 her. Er wirkt in der Weise, dass er eine Kopplung dieser beiden Zahnräder 30 und 32 nur bei Drehung der Trommel 1 in Abwickelrichtung zulässt und bei Drehung in Gegenrichtung die Kopplung in der Weise unterbricht, dass das abtriebsseitige Zahnrad 32 nicht mehr mitdreht. In der Figur 3 erkennt man in der Detailansicht, dass das antriebsseitige Zahnrad 30 mit der Innenverzahnung 34 am Rand 17 der Trommel 1 und das abtriebsseitige Zahnrad 32 mit dem Zahnrad 27 mit dem Schaltnocken 25 kämmt.The FIG. 2 shows in particular the rear view of the built-in cable drum 1. As the synopsis of FIG. 2 and the FIG. 3 is recognizable, the freewheel as sleeve freewheel 29, the non-positive connection between the axes 31 and 33 of a drive-side gear 30 and a driven-side gear 32 ago. It acts in such a way that it allows a coupling of these two gears 30 and 32 only upon rotation of the drum 1 in the unwinding direction and, when rotated in the opposite direction interrupts the coupling in such a way that the driven-side gear 32 does not rotate. In the FIG. 3 can be seen in the detailed view that the drive-side gear 30 meshes with the internal teeth 34 at the edge 17 of the drum 1 and the output-side gear 32 with the gear 27 with the switching cam 25.

Aus der Zusammenschau der einzelnen Elemente wird nun die Funktionsweise der Entriegelung des Bremshebels 10 klarer. Es versteht sich nun von selbst, dass wenn der Bremshebel 10 eingedrückt wird, die Bremsrolle 15 ihre Bremswirkung aufhebt, wobei infolge der Drehfeder 20 die Rastnase 22 den abgestuften Bereich 35 am Schaft 12 hintergreift. Die Bremswirkung an der Trommel 1 ist somit aufgehoben, und aufgrund der gespannten Wickelfeder 4 wird das Anschlusskabel 2 vollautomatisch eingezogen. Der Freilauf 29 verhindert, dass das Zahnrad 27 zusammen mit der Trommel 1 gedreht wird und die Sperrklinke 19 löst. Das Kabel wird vollständig aufgewickelt. Wird nun das Anschlusskabel 2 von der Trommel 1 wieder abgewickelt, wobei dadurch auch die Trommel 1 gedreht wird, wird über den Hülsenfreilauf 29 das abtriebsseitige Zahnrad 32 vom antriebsseitigen 30 angetrieben und kämmt mit dem Schaltnocken-bewehrten Zahnrad 27. Hierdurch drückt der Schaltnocken 25 gegen die Nase 28, so dass die Rastnase 22 den Bremshebel 10 freigibt und aus dem abgestuften Bereich 35 heraus auf den Verschiebebereich 23 springt.From the synopsis of the individual elements, the operation of unlocking the brake lever 10 is now clearer. It goes without saying that when the brake lever 10 is depressed, the brake roller 15 cancels its braking effect, wherein due to the torsion spring 20, the locking lug 22 engages behind the stepped portion 35 on the shaft 12. The braking effect on the drum 1 is thus canceled, and due to the tensioned coil spring 4, the connection cable 2 is retracted fully automatically. The freewheel 29 prevents the gear 27th is rotated together with the drum 1 and releases the pawl 19. The cable is completely wound up. Now, if the connecting cable 2 is unwound from the drum 1 again, thereby also the drum 1 is rotated, the output side gear 32 is driven by the drive freewheel 29 on the drive side 30 and meshes with the switching cam-reinforced gear 27. This presses the control cam 25 against the nose 28, so that the locking lug 22 releases the brake lever 10 and jumps out of the stepped portion 35 out on the sliding portion 23.

Wie aus der Figur 1 und 3 noch zu erkennen ist, ist der Hülsenfreilauf 29 in einem an der Trommelhalterung 9 angeformten Gehäuse 36 untergebracht, welches nur für den Eingriff des an der Halterung gelagerten Zahnrads 32 einen Öffnungsbereich 37 aufweist.Like from the FIG. 1 and 3 can still be seen, the sleeve freewheel 29 is housed in an integrally formed on the drum holder 9 housing 36, which has an opening portion 37 only for the engagement of the gear 32 mounted on the support.
