Description

Die Erfindung betrifft einen Anschlußstutzen für einen Staubsauger zur Verbindung eines Staubsaugerschlauches mit einem Staubsaugermotorgehäuse, einem mit dem Motorgehäuse verbindbaren Stutzen und einer an den Stutzen nach außen anschließenden, ca. 90° betragenden Umlenkung mittels eines Umlenkungsteiles.The invention relates to a connecting piece for a Vacuum cleaner for connecting a vacuum cleaner hose with a vacuum cleaner motor housing, one with the motor housing connectable nozzle and one on the nozzle after 90 ° deflection adjoining the outside by means of a deflection part.

Es sind Anschlußstutzen für Staubsauger bekannt, welche einen Krümmungswinkel zwischen dem Stutzen und einem Umlenkungsteil von 0 - 90° aufweisen. Diese Anschlußstutzen dienen als lösbares Verbindungselement zwischen Staubsaugerschlauch und Staubsaugermotorgehäuse. Es werden hierbei Anschlußstutzen bevorzugt, welche mit dem Saugschlauch eine nicht zu trennende Einheit bilden. Die Trennung erfolgt hierbei zwischen dem Anschlußstutzen und dem Staubsaugermotorgehäuse. Gekrümmte Anschlußstutzen, welche eine ca. 90° betragende Umlenkung aufweisen, werden zumeist an Staubsaugern mit obenliegender Luftzuführung eingesetzt, um ein Abknicken des flexiblen Schlauches zu verhindern und eine ergonomische Bedienung zu ermöglichen. Anschlußstutzen und Grundgerät sind oft so ausgeführt, daß sie eine Rotation des Saugschlauches zum Grundgerät zulassen. Die bekannten gekrümmten Anschlußstutzen sind einteilig mit einem im wesentlichen zylindrischen Strömungsquerschnitt ausgebildet. Fertigungsbedingt weisen diese krümmungsinnenseitig im Strömungskanal einen scharfkantigen Übergang auf. Etwaige Verstopfungen, welche durch den scharfkantigen Übergang gefördert werden, sind bei dem bekannten Stand der Technik insbesondere dann schwer zu entfernen, wenn diese Verstopfungen am schlauchseitigen Schenkel, d. h. im Bereich des Umlenkungsteiles des gekrümmten Anschlußstutzens auftreten, da dieser Bereich sehr schwer zugänglich ist. Weiterhin führt der scharfkantige Übergang zu Strömungsverlusten.There are connecting pieces for vacuum cleaners, which an angle of curvature between the nozzle and one Have deflection part from 0 - 90 °.

Aufgabe der vorliegenden Erfindung ist es, einen gattungsgemäßen Anschlußstutzen handhabungstechnisch zu verbessern.The object of the present invention is a generic Handling spigot too improve.

Gelöst ist diese Aufgabe durch die im Hauptanspruch angegebene Erfindung.This task is solved by the main claim specified invention.

Die Unteransprüche stellen vorteilhafte Weiterbildungen dar.The subclaims represent advantageous developments represents.

Zufolge dieser Ausgestaltung ist ein Anschlußstutzen für einen Staubsauger gegeben, welcher handhabungstechnisch verbessert ist. Dies ist dadurch gelöst, daß der Stutzen und das Umlenkungsteil klappverbunden sind. Bedingt durch diese zweiteilige Ausgestaltung des Anschlußstutzens ist der verstopfungsanfällige Umlenkungsbereich öffenbar, womit dieser im Sichtbereich liegt. Etwaige Verstopfungen können nach Abschwenken des Stutzens vom Umlenkungsteil in einfacher Weise entfernt werden. Beim üblichen Betrieb des Staubsaugers bilden beide Teile eine Einheit, wobei der Anschlußstutzen zur Verbindung des Staubsaugerschlauches mit dem Motorgehäuse auf letzteres aufgesetzt ist. Zur Reinigung des Saugkanals, insbesondere zur Entfernung von Verstopfungen, wird der Anschlußstutzen vom Motorgehäuse entfernt und der Stutzen vom Umlenkungsteil derart vom Benutzer abgeschwenkt, daß eine Öffnung (Revisionsöffnung) entsteht, die den Saugkanal zugänglich macht. Vorteilhafterweise sind der Stutzen und das Umlenkungsteil auch nach Öffnen des Saugkanals miteinander verbunden. Der Stutzen verbleibt nach einem Öffnen unverlierbar an dem Umlenkungsteil und somit am Saugschlauch. Es ist jedoch auch eine Ausbildung denkbar, bei welcher die beiden Teile vollständig voneinander getrennt werden können. Weitergehend ist vorgesehen, daß die Trennebene im wesentlichen senkrecht zu einer Stutzenachse verläuft. Vorteilhafterweise ist hierbei die Trennebene so gelegt, daß an dem Umlenkungsteil krümmungsaußenseitig eine im wesentlichen vollständige Umlenkung ausgebildet ist. Dies bedeutet bei einem um 90° gekrümmten Anschlußstutzen, daß das Umlenkungsteil krümmungsaußenseitig eine im wesentlichen vollständige 90°-Umlenkung aufweist. Demnach besitzt der abschwenkbare Stutzen in dem krümmungsaußenseitigen Bereich des Anschlußstutzens im wesentlichen keine Umlenkung. Vorteilhafterweise ist vorgesehen, daß die Trennebene krümmungsinnenseitig zum Beginn der Krümmung ausgebildet ist. Bevorzugt wird hierbei eine Ausgestaltung, bei der die Trennebene so gelegt ist, daß ein krümmungsaußenseitiger Umlenkungsbereich vollständig an dem Umlenkungsteil und ein krümmungsinnenseitiger Umlenkungsbereich vollständig an dem Stutzen ausgebildet ist. Durch die zweigeteilte Ausführung des Anschlußstutzens besteht fertigungstechnisch die Möglichkeit, die gesamte Kontur des Umlenkungsbereiches sowohl krümmungsaußen- als auch krümmungsinnenseitig zu verrunden. Im bekannten Stand der Technik sind die einteilig ausgebildeten Anschlußstutzen krümmungsinnenseitig mit scharfkantigen Umlenkungen versehen. Dies ist fertigungstechnisch bedingt. Durch die verrundete Kontur des krümmungsinnenseitigen Umlenkungsbereiches ist eine Verstopfungsgefahr beim Erfindungsgegenstand verringert. Weiter ist bei einer derartig angelegten Trennebene zwischen Stutzen und Umlenkungsteil noch von Vorteil, daß der gesamte Umlenkungsbereich freigelegt wird, womit die Zugänglichkeit zu Bereichen mit hoher Verstopfungsneigung deutlich erleichtert und eine einfache Beseitigung der Verstopfungsursache ermöglicht wird. Wie bereits erwähnt, nimmt das Umlenkungsteil zu dem abschwenkbaren Stutzen einen Winkel von ca. 90° ein. Bevorzugt wird hierbei eine Ausbildung, bei welcher die Umlenkung gleich oder größer als 90°, vorzugsweise 90 - 110° beträgt, bezogen auf den Winkel, den die Mittelachsen von Umlenkungsteil und Stutzen einschließen. Hierbei ist die Anordnung derart gewählt, daß die Trennebene mit der Mittelachse des Umlenkungsteils einen spitzen Winkel einschließt. Vorteilhafterweise beträgt der Winkel zwischen der Trennebene und der Mittelachse des Umlenkungsteils 0 - 20°, bevorzugt 10°. Bei einer exakten 90°-Umlenkung verläuft die Trennebene entsprechend parallel zur Mittelachse des Umlenkungsteils. Um die Handhabung mit dem Anschlußstutzen zu optimieren, ist weiter vorgesehen, daß das Umlenkungsteil mit dem Stutzen scharnierverbunden und gegenüberliegend zum Scharnier klipsverbunden ist. Hierzu kann der Stutzen mit einem Scharnierzapfen versehen sein, welcher in einer entsprechenden Aufnahme des Umlenkungsteiles gehalten ist. Dies kann derart realisiert sein, daß der Scharnierzapfen innerhalb der Aufnahme mittels eines Hintergriffes fixiert, jedoch drehbar gelagert ist. Um eine verbesserte Reinigung der beiden Teile des Anschlußstutzens zu ermöglichen, ist es denkbar, den Stutzen nach Abschwenken vom Umlenkungsteil von letzterem zu entfernen, indem der Scharnierzapfen entgegen der Wirkung des Hintergriffes aus der Aufnahme herausgezogen wird. Es sind jedoch auch andere Scharnierverbindungen vorsehbar, auch solche, die keine Trennung von Stutzen und Umlenkungsteil ermöglichen. Eine Sicherung des Stutzens am Umlenkungsteil in Betriebsstellung erfolgt mittels eines dem Scharnier gegenüberliegenden Klipsverschlusses. Hierzu kann das Umlenkungsteil eine Rastnase aufweisen, welche in der Betriebsstellung in eine entsprechende Ausnehmung des Stutzens eingreift. Zum Freilegen des Umlenkungsbereiches wird der Stutzen von dem Umlenkungsteil abgeschwenkt, wobei der Rastvorsprung des Umlenkungsteiles materialbedingt federnd zurückweichen kann. Die Scharnierachse ist hierbei senkrecht zur Stutzenachse ausgerichtet. Weiterhin ist von Vorteil, daß das Umlenkungsteil einen Auflagerand ausbildet, welcher unmittelbar dem Motorgehäuse zugeordnet ist und beabstandet sowie in Stutzenrichtung unterhalb der Klipsverbindung angeordnet ist. In dem durch den Auflagerand gebildeten Raum sind sowohl die Klips- als auch die Scharnierverbindung angeordnet. Dies hat zur Folge, daß ein Abschwenken des Stutzens vom Umlenkungsteil nur nach Abnahme des Anschlußstutzens vom Motorgehäuse erfolgen kann, da erst dann der Verschwenkmechanismus greifbar ist. Vorteilhafterweise besitzt auch der Stutzen zumindest teilweise einen Auflagerand, welcher in Betriebsstellung auf gleicher Ebene mit dem Auflagerand des Umlenkungsteiles liegt. In Betriebsstellung, d. h. bei aufgesetztem Anschlußstutzen auf dem Motorgehäuse ist, der verschwenkbare Stutzen zwischen der Trennebene und dem Auflagerand gesichert. Schließlich erweist es sich als vorteilhaft, daß sich der Auflagerand im Sinne einer zweischaligen Ausgestaltung bis in einen Rohrabschnitt des Umlenkungsteiles erstreckt. In dem zwischen den beiden Schalen gebildeten Raum kann beispielsweise ein Mechanismus zum Lösen der Verbindung zwischen dem Anschlußstutzen und dem Motorgehäuse vorgesehen sein.As a result of this configuration, a connecting piece for given a vacuum cleaner, which is handling is improved. This is solved in that the nozzle and the deflection part are hinged. Conditionally due to this two-part design of the connecting piece the deflection area prone to blockage can be opened, with which this is in the field of vision. Any Blockages can occur after swiveling the nozzle from Deflection part can be removed in a simple manner. At the Normal operation of the vacuum cleaner form both parts one unit, the connecting piece for connection of the vacuum cleaner hose with the motor housing on the latter is put on. To clean the suction channel, especially for the removal of blockages Connection stub removed from the motor housing and the stub pivoted away from the deflection part by the user, that an opening (revision opening) is created that the Makes the suction channel accessible. Advantageously, the Nozzle and the deflection part even after opening the Suction channel connected to each other. The nozzle remains after opening it cannot be lost on the deflection part and thus on the suction hose. However, it is also an education conceivable in which the two parts completely can be separated from each other. Going further provided that the parting plane is substantially perpendicular runs to a nozzle axis. It is advantageous here the parting plane is placed so that on the deflection part An essentially complete outside of the curve Redirection is formed. This means with one 90 ° curved connection piece that the deflection part An essentially complete outside of the curve 90 ° deflection. Accordingly, the swivel has Nozzle in the area outside the curve of the connecting piece essentially no deflection. It is advantageously provided that the parting plane Formed on the inside of the curve at the beginning of the curve is. An embodiment is preferred here, in which the parting plane is placed so that a curvature outside Deflection area completely on the deflection part and a deflection area on the inside of the curve is completely formed on the nozzle. By the two-part version of the connecting piece exists in terms of manufacturing technology, the possibility of the entire contour the deflection area both outside and curvature to round the inside of the curve. In the known state The technology is the one-piece connecting piece Inside of the curve with sharp-edged deflections Mistake. This is due to manufacturing technology. Due to the rounded contour of the inside of the curve Redirection area is a risk of clogging Subject of the invention reduced. Another is one such created parting line between nozzle and Deflection part still advantageous that the entire deflection area is exposed, with which the accessibility to areas with a high tendency to constipation relieved and easy removal of the cause of constipation is made possible. As mentioned earlier, takes the deflection part to the swiveling neck one Angle of approx. 90 °. One is preferred here Training in which the deflection is equal to or greater than 90 °, preferably 90-110 °, based on the Angle that the central axes of the deflection part and Include nozzle. The arrangement is such chosen that the parting plane with the central axis of the Deflection part includes an acute angle. Advantageously is the angle between the parting plane and the central axis of the deflection part 0-20 °, preferably 10 °. With an exact 90 ° deflection the parting plane parallel to the central axis of the Deflection part. To handle with the connector to optimize, it is further provided that the deflecting part hinged to the neck and opposite is clip-connected to the hinge. For this the socket can be provided with a hinge pin be in a corresponding receptacle of the deflecting part is held. This can be realized in this way be that the hinge pin inside the receptacle fixed with a rear grip, but rotatable is stored. To improve cleaning of the two To enable parts of the connecting piece, it is conceivable the nozzle after pivoting away from the deflection part of remove the latter by countering the hinge pin the effect of the rear grip pulled out of the receptacle becomes. However, there are other hinge connections predictable, even those that have no separation of connection piece and deflection part. A backup of the nozzle on the deflection part in the operating position takes place by means of one opposite the hinge Clip fastener. For this purpose, the deflection part can be a Have locking lug, which in the operating position in engages a corresponding recess of the nozzle. The nozzle is used to expose the deflection area pivoted away from the deflection part, wherein the locking projection of the deflection part due to the material springy can recede. The hinge axis is vertical aligned to the nozzle axis. Furthermore from Advantage that the deflecting part forms a support edge, which is directly assigned to the motor housing and spaced and in the nozzle direction below the Clip connection is arranged. In that by the edge of the support formed space are both the clips and the Hinge connection arranged. This has the consequence that a pivoting of the nozzle from the deflection part only after Remove the connector from the motor housing can, since only then can the pivoting mechanism be grasped is. The nozzle advantageously also has at least partially a support edge, which in the operating position on the same level as the edge of the support Deflection part is. In operating position, d. H. at the connector is on the motor housing, the pivotable connection between the parting line and the support edge secured. Finally it turns out as advantageous that the support edge in the sense of a double-shell design down to a pipe section of the deflecting part extends. In the between the two shells formed space can be, for example Mechanism for releasing the connection between the connecting piece and the motor housing may be provided.

Im Bereich der Klipsverbindung K ist unterseitig an diesem Zwischenboden 25 das bereits erwähnte Rastelement 20 angeordnet, welches an seinem freien Ende eine in Betriebsstellung des Anschlußstutzens 6 in das Fenster 19 des Stutzens 8 eingreifende Rastnase 26 aufweist. The deflection part 9 has above the parting plane E. an intermediate floor 25, which is between the Wall 23 of the outer shell and the inner wall 9 ' extends parallel to the parting plane E. In the field of Clip connection K is on the underside of this intermediate floor 25 the already mentioned locking element 20 is arranged, which at its free end is an operating position of the connector 6 in the window 19 of the connector 8th engaging latch 26.

In Betriebsstellung ist der Anschlußstutzen 6 derart auf das Motorgehäuse 3 bzw. auf die Klappe 4 aufgesetzt, daß der Stutzen 8 mit seinem vom Kragen 12 ausgehenden, zylinderförmigen Abschnitt in eine entsprechend ausgeformte gehäuseseitige Aufnahme 27 eintritt. Der Stutzen 8 ist mit dem Umlenkungsteil 9 rastverbunden. Der Saugkanal 10 ist geschlossen, womit eine Verbindung zwischen dem Motorgehäuse 3 und dem Saugschlauch 7 gegeben ist. Der Stutzen 8 ist hierbei im Bereich seines Kragens 12 in dem Aufnahmeraum 22 gefangen, womit hierdurch in Verbindung mit der Klipsverbindung K eine starre Verbindung zur Bildung des Saugkanales 10 gegeben ist. Es ist lediglich ein Verdrehen des gesamten Anschlußstutzens 6 um die Mittelachse y des Stutzens 8 möglich, wozu der Anschlußstutzen 6 mit Rastelementen 28 in entsprechende Aufnahmen eines klappenseitigen, drehbar gelagerten Kupplungs-Tellers 29 eingreifen.In the operating position, the connecting piece 6 is on the motor housing 3 or placed on the flap 4 that the nozzle 8 with its starting from the collar 12, cylindrical section in a correspondingly shaped housing-side receptacle 27 occurs. The stub 8 is latched to the deflection part 9. The suction channel 10 is closed, establishing a connection between the motor housing 3 and the suction hose 7 is given. The connector 8 is in the region of its collar 12 caught in the receiving space 22, which thereby in Connection with the clip connection K a rigid connection is given to form the suction channel 10. It is merely twisting the entire connecting piece 6 possible about the central axis y of the nozzle 8, for which the Connection piece 6 with locking elements 28 in corresponding Recordings of a flap-side, rotatably mounted Engage clutch plates 29.

Es sind zwei Rastelemente 28 vorgesehen, welche um die Mittelachse y um 90° versetzt zu dem Scharnier S bzw. zur Klipsverbindung K an dem Umlenkungsteil 9 angeordnet sind. Die Rastelemente 28 erstrecken sich hierbei über den Auflagerand 21 hinaus.There are two locking elements 28 which are around the Central axis y offset by 90 ° to hinge S or arranged for the clip connection K on the deflection part 9 are. The locking elements 28 extend over here the support edge 21 beyond.

Zur Lösung der Verbindung zwischen Anschlußstutzen 6 und dem klappenseitigen Teller 29 ist an dem Anschlußstutzen 6 im Bereich des Umlenkungsteils 9 eine Drucktaste 30 vorgesehen, mit welcher die Rastelemente 28 entgegen einer Federkraft senkrecht zur Mittelachse y des Stutzens derart verlagert werden, daß diese aus einem Hintergriff im Bereich der tellerseitigen Aufnahme treten. Hiernach kann der Anschlußstutzen 6 von der Klappe 4 abgehoben werden. To solve the connection between connection piece 6 and the flap-side plate 29 is on the connecting piece 6 in the area of the deflection part 9, a push button 30 provided with which the locking elements 28 counter a spring force perpendicular to the central axis y of the nozzle to be relocated in such a way that they fall behind step in the area of the plate-side receptacle. Thereafter, the connector 6 from the flap 4th be lifted off.

Zur Beseitigung von Verstopfungen im Bereich des Anschlußstutzens 6, insbesondere im Umlenkungsbereich B, kann der Stutzen 8 vom Umlenkungsteil 9 um die Scharnierachse z abgeschwenkt werden, wonach der Umlenkungsbereich B freigelegt wird. Es ist somit eine Revisionsöffnung gebildet.To remove blockages in the area of the connection piece 6, in particular in the deflection area B, can the connector 8 from the deflecting part 9 about the hinge axis z be pivoted away, after which the deflection area B is exposed. It is therefore an inspection opening educated.

Sowohl der Umlenkungsbereich B als auch die Kanalabschnitte A und C sind frei zugänglich und somit leicht zu säubern.Both the deflection area B and the channel sections A and C are freely accessible and therefore easy to clean.

Der Stutzen 8 ist unverlierbar an dem Umlenkungsteil 9 bedingt durch den Hintergriff im Bereich der Scharnieraufnahme 17 gehalten.The connector 8 is captive on the deflection part 9 due to the rear grip in the area of the hinge mount 17 held.

Ein Abschwenken des Stutzens 8 vom Umlenkungsteil 9 erfolgt in einfachster Weise, indem der Bediener den Stutzen 8 in Richtung des Pfeiles a in Fig. 6 bewegt, wobei das umlenkungsteilseitige Rastelement 20 federnd nachgibt. Entsprechend greift das Rastelement 20 bei einem Schließen wieder in das Fenster 19 des Stutzens 8 ein.A pivoting of the connector 8 from the deflection part 9 is done in the simplest way by the operator Nozzle 8 moved in the direction of arrow a in Fig. 6, the latching element 20 on the deflection part side being resilient yields. Accordingly, the locking element 20 engages a closing again in the window 19 of the nozzle 8 on.

Um den Anschlußstutzen 6 wiederum in eine Betriebsstellung zu versetzen, ist es zwingend erforderlich, den Stutzen 8 wieder in seine Grundstellung, d. h. in seine verrastete Stellung zurückzuverschwenken, da ansonsten der Saugkanal 10 nicht geschlossen ist. Sollte der Bediener den Stutzen 8 nicht vollständig an dem Umlenkungsteil 9 eingerastet haben, so erfolgt diese Verrastung spätestens bei einem korrekten Aufsetzen des Anschlußstutzens 6 auf die Motorgehäuseklappe 4, da hierbei das an dem Umlenkungsteil 9 angeordnete Rastelement 20 zwangsweise in das Fenster 19 des in dem Aufnahmeraum 22 gefangenen Stutzenkragens 12 eintritt. Around the connecting piece 6 again in an operating position it is imperative to move the Neck 8 back to its basic position, d. H. in his Swivel the locked position back, otherwise the suction channel 10 is not closed. Should the operator the connector 8 is not completely on the deflection part 9 have engaged, this is done at the latest when the connection piece is correctly attached 6 on the engine housing flap 4, since this is the locking element 20 arranged on the deflection part 9 forced into the window 19 of the in the receiving space 22nd captured neck collar 12 occurs.

Bedingt durch die Zweiteilung ist ein Anschlußstutzen 6 gegeben, welcher eine Revisionsöffnung zur Beseitigung von Verstopfungen aufweist, wobei der Stutzen 8 eine Revisionsklappe darstellt. Weiterhin ist durch diese Ausgestaltung ein weicher krümmungsinnenseitiger Umlenkungsbereich B'' realisierbar. Hierdurch wird die Verstopfungsneigung im Umlenkungsbereich B verringert.Due to the division into two, a connecting piece 6 given which an inspection opening for elimination of blockages, the nozzle 8 a Represents inspection hatch. Furthermore, through this Design a soft deflection area inside the curvature B '' realizable. This will increase the tendency to constipation reduced in the deflection area B.
