Description

Die Erfindung betrifft eine Schlauchanordnung für einen Staubsauger, die einen selbsttätig seine Länge ändernden und an seinem Außenumfang mit Rillen ausgestatteten Saugschlauch aufweist, der zumindest in einem Teilbereich sich selbsttätig verlängernd ausgebildet ist, bei welcher Anordnung ferner ein Stützteil vorgesehen ist, das zum Führen eines mit ihm gekoppelten und strömungsmäßig mit dem Saugschlauch verbundenen Saugmundstückes dient und an dem der Saugschlauch zumindest auf einen Teil seiner Länge abgestützt geführt ist, wobei der Saugschlauch mittels eines den Saugschlauch gegen eine selbsttätige Längenänderung sichernden Halteelementes in seiner verkürzten Stellung am Stützteil blockierbar ist.The invention relates to a hose arrangement for a vacuum cleaner, which automatically its length changing suction hose with grooves on its outer circumference has, which is automatically extended at least in a partial area is in which arrangement a support member is also provided, which for guiding one coupled to it and fluidly connected to the suction hose Suction mouthpiece is used and on which the suction hose is guided supported at least over part of its length, the Suction hose by means of a suction hose against an automatic change in length securing retaining element can be blocked in its shortened position on the support part.

Eine derartige Schlauchanordnung ist bereits aus der WO-A-8 607 247 bekannt. Um Platz zu sparen, läßt sich der Schlauch über den Außenumfang des Stützteils streifen oder in das Innere des Stützteils hineinschieben. Dabei werden jeweils die Endstücke des Schlauchs mit den Endstücken des Stützteils verbunden.Such a hose arrangement is already known from WO-A-8 607 247. Around To save space, the hose can be slipped over the outer circumference of the support part or slide into the inside of the support part. The end pieces of the Hose connected to the end pieces of the support part.

Durch die EP-B-O 388 676 ist ein Handstaubsauger, insbesondere ein Bürstensauger bekannt, bei dem die Saugluft von einer im Bodenbereich angeordneten Saugdüse über einen Handsaugschlauch als Steigleitung in einen oberen Bereich des Staubsaugergehäues geführt wird. Der Handsaugschlauch ist in dem der Saugdüse zugewandten Bereich lösbar angeordnet, so daß er für Nebensaugarbeiten abgenommen werden kann. Der Handsaugschlauch ist außerdem mit einem als Verlängerung dienenden Handsaugrohr gekoppelt. Dieses Handsaugrohr ist lösbar am Gehäuse des Handstaubsaugers angebracht und kann zur Durchführung von Nebensaugarbeiten abgenommen werden. Im Bodensaugbetrieb des Handstaubsaugers ist der Handsaugschlauch teleskopartig in das Handsaugrohr eingeschoben, das somit eine magazinartige Aufnahme für den Handsaugschlauch bildet, so daß er an sich lange Handsaugschlauch bei der Durchführung von Saugarbeiten im Bodensaugbetrieb nicht hinderlich ist.EP-B-O 388 676 is a handheld vacuum cleaner, in particular a brush vacuum cleaner is known in which the suction air from a suction nozzle arranged in the bottom region a hand suction hose as a riser in an upper area of the vacuum cleaner housing to be led. The hand suction hose is in the area facing the suction nozzle arranged detachably so that it can be removed for secondary suction work. The hand suction hose is also equipped with an extension hand suction pipe coupled. This hand suction pipe is detachably attached to the housing of the hand vacuum cleaner and can be removed to carry out secondary suction work. in the Bottom suction operation of the hand vacuum cleaner, the hand suction hose is telescopic into that Hand suction tube inserted, which is a magazine-like receptacle for the hand suction hose forms so that it is long hand suction hose when performing Suction in floor suction mode is not a hindrance.

Bei Bodenstaubsaugem ist üblicherweise ein Saugschlauch mit seinem einen Ende an der Saugöffnung des Staubsaugergehäuses und mit seinem anderen Ende an einem Saugrohr angeschlossen. Das Saugrohr dient somit zum Führen eines an ihm aufgesteckten Saugmundstückes und zur strömungsmäßigen Verbindung des Saugmundstükkes mit dem Saugschlauch. Durch den Saugschlauch und das mit ihm gekoppelte Saugrohr ist bei Saugarbeiten ein relativ großer Aktionsradius gegeben. Probleme ergeben sich jedoch beim Verstauen des Staubsaugers an einer Aufbewahrungsstelle, da dann der lange Schlauch oft sehr hinderlich ist.In vacuum cleaners, a suction hose is usually at one end the suction opening of the vacuum cleaner housing and with its other end at one Intake pipe connected. The suction pipe thus serves to guide a plugged onto it Suction mouthpiece and for fluid connection of the suction mouthpiece with the suction hose. Through the suction hose and the suction pipe coupled to it there is a relatively large radius of action for suction work. Problems arise However, when stowing the vacuum cleaner at a storage location, because then the long hose is often very cumbersome.

Der Erfindung liegt die Aufgabe zugrunde, eine Schlauchanordnung für einen Staubsauger, insbesondere einen Bodenstaubsauger, zu schaffen, die sich auf einfache Weise am Stützteil befestigen läßt.The invention has for its object a hose assembly for a vacuum cleaner, in particular to create a vacuum cleaner, which can be easily on Can attach the support part.

Bei einer Schlauchanordnung der eingangs genannten Art wird diese Aufgabe dadurch gelöst, daß der Saugschlauch durch Zusammenwirken des Halteelements am Stützteil mit den Rillen des Saugschlauchs gegen eine selbsttätige Lageänderung gesichert ist. In the case of a hose arrangement of the type mentioned at the outset, this accomplishes this solved that the suction hose by interaction of the holding element on the support member is secured with the grooves of the suction hose against an automatic change of position.

Der Verkürzungsvorgang des Saugschlauches kann dadurch mit Hilfe des vom Staubsauger erzeugten Unterdruckes durchgeführt werden, daß im Bereich des mit dem Saugmundstück strömungsmäßig verbundenen Schlauchendes ein die Luftzufuhr sperrendes Verschlußglied vorgesehen ist.The shortening process of the suction hose can be done with the help of the vacuum cleaner generated negative pressure are carried out that in the area of the Suction mouthpiece fluidly connected hose end on the air supply locking closure member is provided.

Dadurch, daß am Stützteil mindestens ein den Saugschlauch gegen eine selbsttätige Längenänderung sicherndes Halteelement vorgesehen ist, kann der Saugschlauch in einfacher Weise in einer für die Aufbewahrungsstellung des Staubsaugers günstigen verkürzten Länge gehalten werden.Characterized in that at least one suction hose against an automatic on the support part Retaining element securing length change is provided, the suction hose in simple way in a favorable for the storage position of the vacuum cleaner shortened length can be kept.

Die Sicherung des Saugschlauches in seiner verkürzten Stellung ist auf konstruktiv einfache Weise dadurch möglich, daß als Halteelement ein quer zur Längsachse des Saugschlauches in die an seinem Außenumfang vorgesehenen, gewindeartigen Rillen einschiebbarer Verriegelungsfinger vorgesehen ist.Securing the suction hose in its shortened position is constructive easily possible in that a holding element transverse to the longitudinal axis of the Suction hose into the thread-like grooves provided on its outer circumference insertable locking finger is provided.

Besonders vorteilhaft ist es, als Stützteil ein den Saugschlauch aufnehmendes Saugrohr vorzusehen. Durch ein solches Saugrohr wird der Saugschlauch besonders gut gegen ein seitliches Ausweichen gesichert.It is particularly advantageous to use a suction tube that receives the suction hose as a support part provided. Such a suction pipe makes the suction hose particularly good secured against lateral evasion.

Eine weitere Verkürzung der Schlauchanordnung wird dadurch ermöglicht, daß das Stützteil teleskopartig verstellbar ausgebildet ist. Der Saugschlauch kann durch den Unterdruck zunächst, im Bereichder vollen Länge des Stützteiles zusammengezogen . werden. Danach kann das teleskopartig ausgebildete Stützteil zusammen mit dem Saugschlauch noch entsprechend zusammengeschoben werden.A further shortening of the hose arrangement is made possible by the fact that Support part is telescopically adjustable. The suction hose can through the Vacuum initially contracted in the area of the full length of the support part. become. Then the telescopic support part together with the Suction hose can still be pushed together accordingly.

Eine Schmutzbeaufschlagung der Außenseite des im Saugrohr verlaufenden Teiles des Saugschlauches wird vermieden, wenn der Saugschlauch im Bereich des mit dem Saugmundstück gekoppelten Endes des Saugrohres mit dem Saugrohr fest verbunden ist. Die schmutzbeladene Saugluft wird in diesem Falle auf der ganzen Strecke in dem Saugschlauch geführt, so daß eine Verschmutzung der Außenseite des Saug-schlauches nicht möglich ist.A contamination of the outside of the part running in the intake manifold of the suction hose is avoided if the suction hose is in the area of the Suction mouthpiece coupled end of the suction pipe firmly connected to the suction pipe is. The dirt-laden suction air is in this case on the entire route the suction hose, so that contamination of the outside of the suction hose not possible.

Eine Vergrößerung des Aktionsradiuses bei gleicher Schlauchlänge oder eine Verkürzung des Saugschlauches bei gleichem Aktionsradius ist dadurch möglich, daß das im Saugrohr befindliche Ende des Saugschlauches zwischen den beiden Endbereichen des Saugrohres verschiebbar angeordnet ist. Der Saugschlauch kann bei einer solchen Ausbildung der Schlauchanordnung aus dem Saugrohr soweit herausgezogen werden, bis sein Ende in den entsprechenden Endbereich des Saugrohres gelangt.An increase in the radius of action with the same hose length or a shortening the suction hose with the same radius of action is possible in that the End of the suction hose located between the two end regions the suction pipe is slidably arranged. The suction hose can be used for such Formation of the hose assembly pulled out of the intake manifold as far until its end reaches the corresponding end area of the suction pipe.

Eine Verschmutzung der Außenseite des in das Saugrohr einschiebbaren Teiles des Saugschlauches wird dadurch vermieden, daß eine den Saugschlauch umschließende Folienhülle vorgesehen ist, die beim Einschieben des Saugschlauches in das Saugrohr in dem zwischen dem Außenumfang des Saugschlauches und dem Innenumfang des Saugrohres bestehenden Zwischenraum längs erstreckbar ist.Contamination of the outside of the insertable part of the Suction hose is avoided in that a surrounding the suction hose Foil sleeve is provided, which when inserting the suction hose into the suction tube in the between the outer circumference of the suction hose and the inner circumference of the Exhaust pipe existing space is longitudinally extendable.

Vorteilhaft ist es ferner, daß der Saugschlauch in einem Teilbereich als sich selbsttätig verlängernd und in einem weiteren Teilbereich als sich selbsttätig verkürzend ausgebildet ist. Auf diese Weise können die Vorteile beider Arten der selbsttätigen Längenänderung eines Saugschlauches genutzt werden.It is also advantageous that the suction hose is self-acting in a partial area lengthening and trained in a further sub-area as self-shortening is. In this way you can take advantage of both types of automatic length change a suction hose can be used.

Die durch Druckänderungen hervorgerufenen ruckartigen Längenänderungen lassen sich bei einem sich selbsttätig verkürzenden Saugschlauch dadurch zumindest dämpfen, daß der Saugschlauch mit seinem weiteren Teilbereich an dem Stützteil geführt ist. Leave the jerky changes in length caused by pressure changes at least dampen itself with a self-shortening suction hose, that the suction hose is guided with its further partial area on the support part is.

Das Zusammenziehen des Saugschlauches mittels Unterdruck kann in einfacher Weise dadurch ausgelöst werden, daß als Verschlußglied ein von einem mit dem Saugrohr verbundenen Handgriff als fernbetätigbares Ventil vorgesehen ist. So kann der Benutzer eines Staubsaugers nach Beendigung der Saugarbeiten bei noch laufendem Staubsauger das Ventil in seine Schließstellung steuern, so daß dann durch den im Saugschlauch wirksam werdenden hohen Unterdruck ein Zusammenziehen des Saugschlauches erfolgt.The vacuum hose can be contracted in a simple manner are triggered by the fact that as a closure member one of one with the intake manifold connected handle is provided as a remotely operated valve. So the user can a vacuum cleaner after completion of the suction work while still running Vacuum cleaner control the valve in its closed position, so that then in the Suction hose which becomes effective high vacuum a contraction of the suction hose he follows.

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.

Mit 1 ist ein Bodenstaubsauger bezeichnet, mit dessen Saugöffnung 2 ein zusammen mit einem Stützteil 3 eine Schlauchanordnung bildender Saugschlauch 4 verbunden ist. Der Saugschlauch 4 ist als ein sich selbsttätig verlängernder Schlauch ausgebildet. Hierzu weist dieser Saugschlauch 4 eine in seiner Schlauchwand integrierte, als Druckfeder wirkende Spiralfeder auf.1 with a vacuum cleaner is designated, with its suction opening 2 together connected to a support part 3 a suction hose 4 forming a hose arrangement is. The suction hose 4 is designed as an automatically extending hose. For this purpose, this suction hose 4 has an integrated in its hose wall as Compression spring acting coil spring.

Das Stützteil 3 ist als ein teleskopartig ineinander schiebbares Saugrohr 5 ausgeführt. In dieses Saugrohr 5 ist der Saugschlauch 4 eingeschoben, so daß sein entsprechendes Schlauchende 6 im Bereich des mit einem Saugmundstück 7 gekoppelten Endes 8 des Saugrohres 5 liegt. Das Schlauchende 6 ist in diesem Bereich fest mit dem Saugrohr 5 verbunden. In den Strömungsweg vom Saugmundstück 7 zum Saugrohr 5 ist ein Ventil 9 geschaltet. Dieses Ventil 9 kann beispielsweise vom Handriff 10 des Saugrohres 5 aus fernbetätigt werden. Details für eine solche Fernbetätigung sind in der Zeichnung nicht dargestellt. Am Handgriff 10 des Saugrohres 5 ist ferner ein quer zur Längsachse des Saugrohres 5 bzw. Saugschlauches 4 verschiebbarer Verriegelungsfinger 11 angebracht. Dieser Verriegelungsfinger 11 kann in die am Außenumfang des Saugschlauches 4 bestehenden, gewindeartigen Rillen 12 eingeschoben werden.The support part 3 is designed as a telescopically insertable suction tube 5. In this suction tube 5, the suction hose 4 is inserted so that its corresponding Hose end 6 in the area of the end coupled to a suction nozzle 7 8 of the suction pipe 5 lies. The hose end 6 is fixed in this area with the Suction pipe 5 connected. In the flow path from the suction nozzle 7 to the suction pipe 5 a valve 9 is switched. This valve 9 can, for example, from the handle 10 of the Suction pipe 5 can be operated remotely. Details for such remote control are in not shown in the drawing. On the handle 10 of the suction tube 5 is also a cross locking fingers displaceable to the longitudinal axis of the suction pipe 5 or suction hose 4 11 attached. This locking finger 11 can in the on the outer circumference of the suction hose 4 existing, thread-like grooves 12 inserted become.

Während der Durchführung von Saugarbeiten befindet sich der Verriegelungsfinger 11. außer Eingriff mit den Rillen 12, so daß sich der Saugschlauch 4 selbsttätig auf seine volle Länge ausdehnen kann.The locking finger 11 is located while performing suction work. out of engagement with the grooves 12, so that the suction hose 4 automatically on its can stretch full length.

Nach Beendigung der Saugarbeiten wird der zusammendrückbare Saugschlauch 4 entweder von Hand oder durch die Krafteinwirkung des Unterdruckes in das Saugrohr 5 eingeschoben bzw. eingezogen. Um den vollen Unterdruck zur Wirkung zu bringen, wird das Ventil 9 bei noch laufendem Staubsauger geschlossen. Die in der Wand des Saugschlauches 4 eingearbeitete Spiralfeder ist hinsichtlich ihrer Federkonstanten so ausgelegt, daß ein Zusammendrücken des Saugschlauches 4 durch die Kraft des vollen Unterdruckes möglich ist, durch den während des Saugbetriebes herrschenden Unterdruck dagegen keine wesentliche Verkürzung des Saugschlauches 4 bewirkt wird.After completion of the suction work, the compressible suction hose 4 either by hand or by the force of the vacuum in the intake manifold 5 inserted or retracted. To bring the full vacuum to work, the valve 9 is closed while the vacuum cleaner is still running. The in the wall of the Suction hose 4 incorporated spiral spring is so in terms of their spring constants designed that a compression of the suction hose 4 by the force of the full Negative pressure is possible due to the prevailing during suction operation Vacuum, however, does not significantly shorten the suction hose 4 becomes.

Reicht der bei geschlossenem Ventil 9 anstehende Unterdruck nicht aus um den im Saugrohr 5 befindlichen Teil des Saugschlauches 4 auf seine kürzest mögliche Länge zusammenzudrücken, dann kann der Saugschlauch 4 noch zusäzlich von Hand in das Saugrohr 5 hineingedrückt werden. Danach wird der Verriegelungsfinger 11 entsprechend betätigt, so daß er in eine der Rillen 12 eingreift und damit den Saugschlauch 4 in seiner zusammengedrückten Stellung blockiert.If the vacuum present when the valve 9 is closed is not sufficient by the Suction pipe 5 located part of the suction hose 4 to its shortest possible length to squeeze, then the suction hose 4 can also by hand in that Suction pipe 5 are pressed in. Then the locking finger 11 becomes corresponding actuated so that it engages in one of the grooves 12 and thus the suction hose 4th blocked in its compressed position.

Bei einer Ausbildung des Saugrohres 5 als Teleskoprohr, wie dies in der Zeichnung angedeutet ist, besteht die Möglichkeit, den Saugschlauch 4 zunächst in das sich in seiner verlängerten Stellung befindliche Saugrohr 5 durch die Unterdruckkraft einzuziehen und mittels des Verriegelungsfingers 11 in dieser Stellung zu verriegeln. Danach kann durch Zusammenschieben des Teleskoprohres eine entprechende weitere Verkürzung der Schlauchanordnung vorgenommen werden. Die nach einer Verkürzung des Saugschlauches 4 noch außerhalb des Saugrohres 5 verbleibende Länge des Saugschlauches 4 läßt eine platzsparende Aufbewahrung von Schlauchanordnung und Staubsauger zu. Dabei kann, wie in Fig. 2 dargestellt, das Saugrohr 5 in eine entsprechende, am Staubsaugergehäuse vorgesehene Halterung eingesteckt werden. Die restliche Schlauchlänge erstreckt sich dann oberhalb des Staubsaugergehäuses zwischen der Saugöffnung 2 und dem oberen Ende des Saugrohres 5. Es wird somit kein zusätzlicher Raum seitlich vom Staubsauger für die Unterbringung des Saugschlauches 4 benötigt.When the suction tube 5 is designed as a telescopic tube, as shown in the drawing is indicated, there is the possibility of the suction hose 4 first in the its extended position located suction pipe 5 to pull in by the vacuum force and to lock in this position by means of the locking finger 11. After that can by pushing the telescopic tube together a corresponding Shortening the hose arrangement can be made. The one after a shortening of the suction hose 4 still outside of the suction pipe 5 remaining length the suction hose 4 allows space-saving storage of the hose arrangement and vacuum cleaners too. As shown in FIG. 2, the suction pipe 5 can be inserted into a corresponding provided on the vacuum cleaner housing. The remaining hose length then extends above the vacuum cleaner housing between the suction opening 2 and the upper end of the suction pipe 5. It is thus no additional space to the side of the vacuum cleaner to accommodate the suction hose 4 needed.

Neben dem beschriebenen Ausführungsbeispiel mit am Saugrohr 5 befestigtem Schlauchende 6 des Saugschlauches 4 gibt es auch die Möglichkeit, dieses Schlauchende 6 verschiebbar im Saugrohr 5 anzuordnen. Es müssen dann an beiden Enden des Saugrohres 5 entsprechende Anschläge und Dichtungen vorgesehen werden, durch die der Verschiebeweg des Saugschlauches 4 im Saugrohr 5 begrenzt wird. Bei einer solchen Ausführungsvariante kann also der Saugschlauch 4 aus dem Saugrohr 5 herausgezogen werden. Damit ergibt sich ein größerer Aktionsradius, wenn die gleiche Schlauchlänge beibehalten wird. Es kann aber auch unter Beibehaltung des gleichen Aktionsradius die Schlauchlänge entsprechend der Länge des Saugrohres 5 gekürzt werden. Dies führt dann dazu, daß nach dem Magazinieren des Saugschlauches 4 im Saugrohr 5 eine noch kürzere Schlauchlänge verbleibt, was die platzsparende Verstauung des Staubsaugers 1 weiter erleichtert.In addition to the described embodiment with attached to the intake manifold 5 Hose end 6 of the suction hose 4 there is also the possibility of this hose end 6 slidably to arrange in the intake manifold 5. It must then be on both ends of the suction pipe 5 corresponding stops and seals are provided, through which the displacement of the suction hose 4 in the suction pipe 5 is limited. at Such an embodiment variant can therefore suction hose 4 from suction pipe 5 be pulled out. This results in a larger radius of action if the same Hose length is maintained. But it can also keep the same Radius of action shortened the hose length according to the length of the suction pipe 5 become. This then leads to the fact that after magazining the suction hose 4 an even shorter hose length remains in the suction pipe 5, which is the space-saving Stowage of the vacuum cleaner 1 further facilitated.

Bei einer verschiebbaren Anordnung des Saugschlauches 4 im Saugrohr 5 kann die Außenseite des entsprechenden Schlauchabschnittes mit der verschmutzten Innenwandurig des Saugrohres 5 in Berührung kommen und dadurch verschmutzt werden. Dies läßt sich vermeiden, wenn dem entsprechenden Schlauchabschnitt eine ihn umschließende Folienhülle zugeordnet wird. Diese Folienhülle kann einerseits mit dem entnprechenden Ende des Saugrohres 5 und andererseits mit dem in das Saugrohr 5 eintauchenden Schlauchende 6 verbunden werden. Beim Hin- und Herschieben des Schlauchendes 6 im Saugrohr 5 macht die Folienhülle diese Bewegungen mit, so daß keine Berührung und damit keine Verschmutzung der Außenseite des Saugschlauches 4 an der Innenwand des Saugrohres 5 erfolgt. With a displaceable arrangement of the suction hose 4 in the suction pipe 5, the Outside of the corresponding hose section with the dirty inner wall of the suction pipe 5 come into contact and become dirty. This can be avoided if the hose section in question surrounds it Foil sleeve is assigned. This film cover can be used with the corresponding end of the suction pipe 5 and on the other hand with the into the suction pipe 5 immersed hose end 6 are connected. When pushing the Hose end 6 in the suction tube 5 makes the film cover with these movements, so that no contact and therefore no contamination of the outside of the suction hose 4 takes place on the inner wall of the suction pipe 5.

Günstig für die Erzielüng einer möglichst kurzen verbleibenden Restlänge des Saugschlauches 4 im Ruhezustand des Staubsaugers kann es sein, den Saugschlauch 4 in einem Teilbereich als sich selbsttätig verlängernden Schlauch und in einem weiteren Teilbereich als sich selbsttätig verkürzenden Schlauch auszubilden.Favorable for achieving the shortest possible remaining length of the suction hose 4 in the idle state of the vacuum cleaner, it can be the suction hose 4 in one section as an automatically extending hose and in another To form part of the area as a self-shortening hose.
