A sleeve surrounding the outer tube also covers the guide piece with the blocking member (8), the blocking member (8) being adjustable by means of an actuating knob (15) in such a way that a catch member (4) which engages in a catch notch (3) of the inner tube (1) can be adjusted from a catch position into a release position. <IMAGE>

Description

Die Erfindung betrifft ein längenveränderbares Saugrohr gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a variable-length intake manifold according to the preamble of claim 1.

Ein bekanntes längenveränderbares Saugrohr für Staubsauger (US-PS 3351363) weist zwei ineinander verschiebbar gelagerte Rohre auf, wobei das Innenrohr neben einer sich in Achsrichtung erstreckenden Führungsnut auch mehrere in Achsrichtung mit Abstand voneinander angeordnete Rastkerben aufweist. An dem im Außenrohr liegenden Ende trägt das Innenrohr eine Dichtung, die an der Innenwandung des Außenrohres anliegt und das Innenrohr zentriert führt. Das das Innenrohr übergreifende Ende des Außenrohres ist zylindrisch aufgeweitet, wobei in der Aufweitung ein Führungsstück festgesetzt ist, welches das Innenrohr zentriert hält und in dem das Innenrohr gleitend geführt ist. Im Führungsstück befindet sich ein radial gerichteter Durchbruch, in dem ein radial verstellbar angeordnetes Rastglied sitzt, das in seiner Raststellung mit einer der Rastkerben zusammenwirkt und die Axialverschiebung der Rohre verhindert. Das rund ausgebildete Rastglied steht in Wirkverbindung mit einer als Sperrglied dienenden schiefen Ebene, die gegenüber dem Rastglied verstellbar angeordnet ist und in der Raststellung das Sperrglied in die betreffende Rastkerbe radial unverstellbar eintaucht. Durch Verstellen des Sperrgliedes in eine Freigabestellung wird ein radial außerhalb des Sperrgliedes liegender Freiraum freigegeben, in welchen das Rastglied wandert, wenn die Rohre relativ zueinander verstellt werden und das Rastglied aus der Rastvertiefung ausgehoben wird. Das Sperrglied ist dabei einstückig mit einer Hülse gekoppelt, die auf dem aufgeweiteten Abschnitt des Außenrohres beweglich gelagert ist und manuell verstellt werden kann. Das im Spalt zwischen dem aufgeweiteten Abschnitt des Außenrohres und dem Innenrohr angeordnete Führungsstück wird durch radial nach innen gerichtetes Umbördeln des freien Randes des Außenrohres gegen Verstellen in Achs- und Umfangsrichtung gesichert. Das Aufweiten und anschließende Umbördeln des Außenrohres erfordert einen hohen Aufwand an Werkzeugen für den Herstellungsprozeß, wobei das Umbördeln zu einem das zügige Gleiten verhindernden Zusammendrücken des Führungsstücks führen kann. Zudem ist das maßgenaue Aufweiten schwierig auszuführen, so daß auch hierdurch ein zu enger Sitz des Führungsstücks am Innenrohr eintreten kann bzw. bei zu großer Aufweitung ein hinreichend dichter Abschluß nicht gewährleistet werden kann.A known length-adjustable suction tube for vacuum cleaners (US-PS 3351363) has two tubes which are displaceable one inside the other, the inner tube not only having a guide groove which extends in the axial direction but also a plurality of locking notches which are arranged at a distance from one another in the axial direction. At the end lying in the outer tube, the inner tube carries a seal which bears against the inner wall of the outer tube and guides the inner tube in a centered manner. The end of the outer tube that overlaps the inner tube is cylindrically widened, a guide piece being fixed in the widening, which keeps the inner tube centered and in which the inner tube is slidably guided. In the guide piece there is a radially directed opening, in which a radially adjustable locking member is seated, which in its locking position cooperates with one of the locking notches and prevents the tubes from being axially displaced. The round locking member is operatively connected to an inclined plane serving as a locking member, which is adjustably arranged with respect to the locking member and immerses the locking member radially non-adjustable in the locking position in the locking position. By moving the locking member into a release position, a free space lying radially outside the locking member becomes released, in which the locking member moves when the tubes are adjusted relative to each other and the locking member is lifted out of the recess. The locking member is integrally coupled to a sleeve which is movably mounted on the widened section of the outer tube and can be adjusted manually. The guide piece arranged in the gap between the widened section of the outer tube and the inner tube is secured against adjustment in the axial and circumferential directions by flanging the free edge of the outer tube in a radially inward direction. The widening and subsequent flanging of the outer tube requires a high expenditure of tools for the manufacturing process, the flanging can lead to a compression of the guide piece which prevents rapid sliding. In addition, the dimensionally accurate expansion is difficult to carry out, so that this too can result in the guide piece being too tightly seated on the inner tube or, if the expansion is too great, a sufficiently tight seal cannot be guaranteed.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Saugrohr gemäß dem Oberbegriff des Anspruchs 1 Maßnahmen zu treffen, durch die ein vereinfachter Aufbau erzielt wird.The invention has for its object to take measures in a suction pipe according to the preamble of claim 1, through which a simplified structure is achieved.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved according to the invention by the characterizing features of claim 1.

Bei einer Ausgestaltung eines Saugrohres gemäß der Erfindung entfällt ein Aufweiten des Außenrohres im Bereich der Rastvorrichtung, so das das Außenrohr bei unverändertem Durchmesser frei auslaufen kann. Im Mantel des Außenrohres ist lediglich ein Durchbruch für das angepaßte Führungsstück erforderlich, das darin gegen Verschieben in axialer wie in Umfangsrichtung gesichert ist. Das Führungsstück stützt sich dabei vorzugsweise in seinem Randbereich auf dem Außenrand des Durchbruchs ab, so daß es nicht mit dem Innenrohr in Gleitanlage treten kann. Die Sicherung des Führungsstücks mit dem eingelegten Rastglied erfolgt durch die aufgeschobene Hülse, die den Mantel des Außenrohres und auch das Führungsstück umschließt. Wenn das nach Art einer schiefen Ebene ausgebildete Sperrglied einstückig mit der Hülse verbunden ist, kann das Sperrglied in Umfangsrichtung verlaufen, so daß durch Drehen der Hülse das Rastglied aus bzw. in seine Sperrstellung gedrückt werden kann. Erstreckt sich das Sperrglied in Achsrichtung, braucht die Hülse lediglich in Achsrichtung verschiebbar zu sein. In beiden Fällen ist es zweckmäßig, die Hülse durch die Kraft einer Feder so zu beaufschlagen, daß sie das Sperrglied selbsttätig in die Verriegelungsstellung bewegt. Vorzugsweise ist jedoch die Hülse unverstellbar gegenüber dem Außenrohr angeordnet und gegebenenfalls unmittelbar daran befestigt. Das Sperrglied ist dann als separat verstellbares Bauteil auszubilden und über ein Verbindungsstück mit einem an der Außenseite der Hülse angeordneten Betätigungsknopf zur manuellen Betätigung zu verbinden. Hierfür ist insbesondere zwischen dem Führungstück und der Hülse das gegen die Kraft einer Feder verstellbare Sperrglied gelagert. Für seine Betätigung ist dann ein Schlitz im Mantel der Hülse erforderlich, durch den das Verbindungsstück bis zum Betätigungsknopf greift. Das Sperrglied kann dabei in Umfangsrichtung verstellbar sein, wenn auch der Schlitz in Umfangsrichtung verläuft und ist insbesondere axial verschiebbar bei axial verlaufendem Schlitz. Die Hülse kann das Außenrohr eng umschließen und im Bereich des Führungsstücks eine radiale Ausformung aufweisen, die auch das verstellbare Sperrglied führen und auf welcher der Betätigungsknopf angeordnet sein kann. Zur Zentrierung und dichten Führung des Innenrohres 1 ist es zweckmäßig, der Hülse im Bereich des benachbarten Endes des Außenrohres einen Dichtring zuzuordnen, der einstückig daran angeformt oder als separates Bauteil daran festgesetzt werden kann. Außerdem kann die Hülse einen radial nach innen gerichteten Zapfen tragen, welcher in die in das Innenrohr eingeprägte Längs-Führungsnut eingreift und eine Relativverdrehung zwischen den Rohren verhindert. Zur Sicherung der Hülse in axialer Richtung ist es zweckmäßig, wenn sie mit einem Bund einerseits an der Stirnkante des Außenrohres anliegt und andererseits mit dem im Außenrohr gehaltenen Führungsstück beispielsweise über eine Rastverbindung in Eingriff steht.In one embodiment of a suction pipe according to the invention, there is no need to widen the outer pipe in the area of the latching device, so that the outer pipe can run freely with the same diameter. In the jacket of the outer tube, only an opening for the adapted guide piece is required, which is secured against displacement in the axial and in the circumferential direction. The guide piece is preferably supported in its edge region on the outer edge of the opening, so that it cannot step into the sliding system with the inner tube. The guide piece with the inserted locking element is secured by the slid-on sleeve, which encloses the jacket of the outer tube and also the guide piece. If the locking member designed in the manner of an inclined plane is integrally connected to the sleeve, the locking member can extend in the circumferential direction so that the locking member can be pressed out or into its locking position by rotating the sleeve. If the locking member extends in the axial direction, the sleeve need only be displaceable in the axial direction. In both cases, it is expedient to apply the force of a spring to the sleeve so that it automatically moves the locking member into the locking position. However, the sleeve is preferably arranged such that it cannot be adjusted relative to the outer tube and, if appropriate, is fastened directly thereon. The locking member is then to be designed as a separately adjustable component and to be connected via a connecting piece to an actuating button arranged on the outside of the sleeve for manual actuation. For this purpose, the locking member adjustable against the force of a spring is mounted in particular between the guide piece and the sleeve. A slot in the jacket of the sleeve is then required for its actuation, through which the connecting piece reaches as far as the actuation button. The locking member can be adjustable in the circumferential direction if the slot also runs in the circumferential direction and is in particular axially displaceable in the case of an axially extending slot. The sleeve can tightly enclose the outer tube and have a radial shape in the region of the guide piece, which also guide the adjustable locking member and on which the actuating button can be arranged. For centering and tight guiding of the inner tube 1, it is expedient to assign a sealing ring to the sleeve in the region of the adjacent end of the outer tube, which can be integrally formed thereon or attached to it as a separate component. In addition, the sleeve can Wear a radially inward-facing pin which engages in the longitudinal guide groove stamped into the inner tube and prevents relative rotation between the tubes. To secure the sleeve in the axial direction, it is expedient if, on the one hand, it rests with a collar on the front edge of the outer tube and, on the other hand, it engages with the guide piece held in the outer tube, for example via a snap-in connection.

Die Erfindung ist nachfolgend anhand der Zeichnungen eines Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to the drawings of an exemplary embodiment.

Ein teleskopartig in der Länge veränderbares Saugrohr für Staubsauger weist ein Innenrohr 1 auf, das mit einer in Achsrichtung sich erstreckenden eingeprägten Führungsnut 2 versehen ist. In die Mantelfläche des Innenrohres 1 sind auch vorzugsweise mehrere in Achsrichtung mit Abstand voneinander angeordnete Rastkerben 3 eingedrückt, die für das Zusammenwirken mit einem runden Rastglied 4 ausgebildet sind. Das Rastglied 4 greift in der dargestellten Verriegelungsstellung in die Rastkerbe ein und sitzt im übrigen in einem Ausschnitt 5 eines Führungsstückes 6, das mit seiner Randzone auf dem Außenrand eines Durchbruchs, der in der Mantelfläche eines das Innenrohr 1 mit Spiel umgebenenden Außenrohres 7 vorgesehen ist. Das Führungstück 6 greift in diesen Durchbruch 7.1, formschlüssig und dicht hinein und ist so gegen Verstellen in Achsrichtung und in Umfangsrichtung gesichert. Sein Bund 6a positioniert es dabei gleichzeitig in radialer Richtung, so daß es nicht gegen das Innenrohr 1 gedrückt werden kann. Das Führungsstück 6 führt außer dem Rastglied 4 auch einen senkrecht dazu und in Rohrlängsrichtung verschiebbar gelagertes Sperrglied 8, das gegen die Kraft einer Feder 9 verschoben werden kann. In der dargestellten Verriegelungsstellung greift das Sperrglied 8 radial außen auf das Rastglied 4 und hält dasselbe in der Rastkerbe 3. Durch Verschieben des Sperrgliedes 8 gegen die Kraft der Feder 9 soweit (vorliegend gemäß Figur 1 nach rechts), daß es aus dem Überdeckungsbereich mit dem Rastglied 4 gelangt, dann ist radial außerhalb des Rastgliedes 4 in der dann erreichten Freigabestellung ein Freiraum freigegeben, in den das Rastglied 4 wandern kann. Der Freiraum ist dabei so hoch bemessen, daß das Rastglied 4 aus dem Wirkungsbereich des Innenrohres 1 bzw. der Rastkerben 3 gelangt. Dabei sind die Flanken der Rastkerben 3 so geneigt, daß durch Relativverschiebung der Rohre 1,7 das Rastglied 4 selbsttätig aus der Rastkerbe ausgehoben wird. Der Freiraum für das Rastglied 4 ist durch einen Anschlagsteg 10 radial begrenzt, der einstückig mit dem Sperrglied 8 verbunden sein kann. Das Außenrohr 7 besitzt dabei einen durchgehend gleichen Durchmesser, soweit das Innenrohr damit in Eingriff treten kann. Das Außenrohr 7 trägt im Bereich der das Führungsstück 6 beinhaltenden Rastvorrichtung eine eng an der Mantelfläche anliegende Hülse 11, die lediglich im Bereich des Führungsstückes 6 und dem daran verschiebbar gehaltenen Sperrglied 8 eine radiale Ausformung 12 aufweist. Die Ausformung übergreift die beiden Teile 6,7 so, daß sie gegen Radialverstellung gesichert sind. Dabei liegt der Anschlagsteg 10 an der Innenseite der Ausformung 12 gleitend an. In der Ausformung 12 befindet sich ein in axialer Richtung verlaufender Schlitz 13, durch den ein Verbindungssteg 14 greift, welcher einstückig mit einem auf der Oberseite der Ausformung 12 angeordneten, verschiebbaren Betätigungsknopf 15 verbunden ist und in einer lösbaren Steckverbindung mit dem Sperrglied 8 steht. Parallel zum Verbindungssteg 14 sind an den Betätigungsknopf 15 noch Begrenzungsstege 16 angeformt, welche auf das Führungsstück 6 bzw. das als Verriegelungsschieber ausgebildete Sperrglied 8 greifen.A telescopically variable in length suction tube for vacuum cleaners has an inner tube 1, which is provided with an embossed guide groove 2 extending in the axial direction. A plurality of locking notches 3, which are arranged at a distance from one another in the axial direction and are designed to interact with a round locking member 4, are also preferably pressed into the lateral surface of the inner tube 1. The locking member 4 engages in the locking position shown in the locking notch and sits in the rest of a cutout 5 of a guide piece 6, which with its edge zone on the outer edge of an opening in the outer surface of the inner tube 1 with play surrounding outer tube 7 is provided. The guide piece 6 engages in this opening 7.1, positively and tightly and is thus secured against adjustment in the axial direction and in the circumferential direction. Its collar 6a positions it simultaneously in the radial direction, so that it cannot be pressed against the inner tube 1. In addition to the locking member 4, the guide piece 6 also guides a locking member 8 which is mounted perpendicularly to it and is displaceable in the longitudinal direction of the tube and which can be moved against the force of a spring 9. In the locking position shown, the locking member 8 engages radially on the outside on the locking member 4 and holds the same in the locking notch 3. By moving the locking member 8 against the force of the spring 9 so far (in the present case according to FIG. 1 to the right) that it comes out of the overlap area with the Locking member 4 arrives, then a free space is released radially outside the locking member 4 in the release position then reached, in which the locking member 4 can move. The free space is dimensioned so high that the locking member 4 comes out of the effective area of the inner tube 1 or the locking notches 3. The flanks of the locking notches 3 are inclined so that the locking member 4 is automatically lifted out of the locking notch by relative displacement of the tubes 1,7. The free space for the locking member 4 is radially limited by a stop web 10, which can be integrally connected to the locking member 8. The outer tube 7 has the same diameter throughout, insofar as the inner tube can engage with it. The outer tube 7 carries, in the region of the latching device containing the guide piece 6, a sleeve 11 which lies closely against the outer surface and which has a radial shape 12 only in the area of the guide piece 6 and the locking member 8 held thereon. The shape overlaps the two parts 6, 7 so that they are secured against radial adjustment. The stop web 10 lies on the inside of the formation 12 in a sliding manner. In the formation 12 there is an in Slit 13 extending axially, through which a connecting web 14 engages, which is integrally connected to a displaceable actuating button 15 arranged on the top of the formation 12 and is in a releasable plug connection with the locking member 8. In parallel to the connecting web 14, limiting webs 16 are also formed on the actuating button 15, which engage the guide piece 6 or the locking member 8 designed as a locking slide.

Da die Hülse 11 das Außenrohr 7 über mehr als den halben Umfang dicht umschließt und das Führungsstück 6 in die angepaßte radiale Ausformung 12 eingreift, ist die Hülse 11 gegen Verdrehen und radiales Verstellen gesichert. Zur Festlegung in axialer Richtung weist sie einen Anschlagbund 17 auf, der vor die freie Stirnkante 18 des Außenrohrendes greift, während das axial gegenüberliegende Ende der Hülse 11 bzw. der Ausformung 12 mittels einer radial nach innen gerichteten Rastnase 18 das Führungsstück 6 hintergreift. Die Hülse 11 ist damit unverstellbar gegenüber dem Außenrohr 7 angeordnet, kann jedoch durch Ausheben der Rastnase 19 wieder gelöst werden.Since the sleeve 11 tightly encloses the outer tube 7 over half the circumference and the guide piece 6 engages in the adapted radial shape 12, the sleeve 11 is secured against twisting and radial adjustment. For fixing in the axial direction, it has a stop collar 17 which engages in front of the free end edge 18 of the outer tube end, while the axially opposite end of the sleeve 11 or the formation 12 engages behind the guide piece 6 by means of a radially inwardly directed latching lug 18. The sleeve 11 is thus arranged in an unadjustable manner with respect to the outer tube 7, but can be released again by lifting out the catch 19.

Zur Zentrierung des Innenrohres 1 im Außenrohr 7 dient einerseits ein vorliegend einstückig mit dem Anschlagbund 17 verbundener Dichtring 20, der das Innenrohr dicht umgibt und zentriert sowie gleitbar führt. Außerdem ist an dem in das Außenrohr 7 eingeschobenen Ende des Innenrohres ein Dichtungsring 21 angeordnet, der ebenfalls den Spalt zwischen den beiden Rohren 1,7 überbrückt und neben einem luftdichten Abschluß auch die Zentrierung zwischen den Rohren 1,7 bewerkstelligt. Die Hülse 11 trägt zudem einen radial nach innen gerichteten Zapfen 22, der in die Führungsnut 2 eingreift und so eine Relativverdrehung der Rohre 1,7 unterbindet.For centering the inner tube 1 in the outer tube 7, on the one hand, a sealing ring 20, which in the present case is integrally connected to the stop collar 17, is used, which surrounds the inner tube tightly and centers and slidably guides. In addition, a sealing ring 21 is arranged at the end of the inner tube inserted into the outer tube 7, which also bridges the gap between the two tubes 1.7 and, in addition to an airtight seal, also accomplishes the centering between the tubes 1.7. The sleeve 11 also carries a radially inwardly directed pin 22 which engages in the guide groove 2 and thus prevents a relative rotation of the tubes 1,7.

Ein so ausgebildetes Saugrohr kann in einer automatischen Fertigungseinrichtung zusammengebaut werden, nachdem lediglich das Führungsstück 6 mit dem Sperrglied 8 und der Feder 9 in den angepaßten Durchbruch im Außenrohr 7 radial von außen einzusetzen ist und anschließend nur das Innenrohr mit bereits aufgefädelter Hülse 11 in das Außenrohr eingeführt und die Hülse auf das Außenrohr und die daran festgesetzten Teile 6,8,9 aufgeschoben werden muß. Es braucht dann lediglich in radialer Richtung noch der Betätigungsknopf 15 aufgesteckt zu werden.A suction pipe designed in this way can be assembled in an automatic production device after only the guide piece 6 with the locking member 8 and the spring 9 is to be inserted radially from the outside into the adapted opening in the outer pipe 7 and then only the inner pipe with the sleeve 11 already threaded onto the outer pipe introduced and the sleeve must be pushed onto the outer tube and the attached parts 6,8,9. The actuating button 15 then only needs to be plugged in in the radial direction.

Gemäß der Ausführungsform nach Fig. 4 kann bei sonst gleichem Aufbau im Sperrglied 8 eine dem Rastglied 4 angepaßte Aussparung 23 vorgesehen sein, wobei die Feder 9 als Zugfeder auszubilden ist. In der dargestellten Entriegelungsstellung können die Rohre 1,7 axial frei gegeneinander verschoben werden, wobei das Rastglied 4 nach oben in die Aussparung 23 ausgehoben wird, wenn sich keine Rastkerbe 3 unter ihr befindet. Wird bei in eine Rastkerbe 3 eingefallenem Rastglied 4 der Betätigungsknopf 15 losgelassen und durch die Zugfeder 9 z. B. in der Zeichnung nach rechts gezogen, bis das Sperrglied 8 über dem Rastglied 4 steht, dann ist das Rastglied 4 in der Rastkerbe 3 arvetiert und ein weiteres axiales Verschieben der Rohre 1,7 nicht mehr möglich.According to the embodiment according to FIG. 4, a recess 23 adapted to the locking member 4 can be provided in the locking member 8, otherwise the structure being the same, the spring 9 being designed as a tension spring. In the unlocking position shown, the pipes 1, 7 can be freely moved axially against one another, the latching member 4 being lifted upward into the recess 23 when there is no latching notch 3 below it. If the actuating button 15 is released when the latching member 4 has fallen into a latching notch 3 and the tension spring 9 z. B. drawn to the right in the drawing until the locking member 8 is above the locking member 4, then the locking member 4 is arvetiert in the locking notch 3 and a further axial displacement of the tubes 1.7 is no longer possible.
