Abstract

The suction pipe (10) has an outer pipe (12) and an inner pipe (11) which, with a deformation region, forms a catch strip (20) with catch recesses (21). A positive fit safeguard, which prevents relative rotation between the inner and the outer pipes (11, 12), has an axial groove (35) or axial spring which is machined into the respective pipe wall (22) on the inner or outer pipe. A catch body (25), forming a separate component, can be displaced into a locking or release position in relation to the respective catch recess (21) by means of the holding-down device (16) which constitutes a control body and is movable independently of the catch body (25). The suction pipe (10) allows both simple production and simple operation. <IMAGE>

Description

Die Erfindung betrifft ein teleskopierbares Staubsauger-Saugrohr, wie es entsprechend dem Oberbegriff des Patentanspruchs 1 durch die US-A-3 351 363 bekanntgeworden ist.The invention relates to a telescopic vacuum cleaner suction pipe, as has become known according to the preamble of claim 1 by US-A-3 351 363.

Das durch die US-A-3 351 363 (s. dort Fig. 13-16) bekannte Außenrohr (Pos. 18) weist endseitig eine muffenartige Aufweitung (Pos. 81) auf, welche der Aufnahme eines kreisringförmigen Kunststoff-Dichtkörpers (Pos. 80) gestattet, welchem auch eine Axialrippe (Pos. 83) zugeordnet (aber nicht einstückig angeformt) ist, die mit einer axialen Längsnut (Pos. 28a) zusammenwirkt. Die hiermit geschaffene Verdrehsicherung ist zur Umfangszentrierung erforderlich, damit die axiale Rastverstellung (Pos. 26, 44) in Überdeckung verbleiben und damit funktionieren kann.The outer tube (item 18) known from US-A-3 351 363 (see there Fig. 13-16) has a sleeve-like widening (item 81) at the end, which accommodates an annular plastic sealing body (item. 80), to which an axial rib (item 83) is also assigned (but not integrally formed), which interacts with an axial longitudinal groove (item 28a). The anti-rotation device created in this way is required for circumferential centering so that the axial locking adjustment (item 26, 44) remains in overlap and can thus function.

Die muffenartige Aufweitung (Pos. 81) gemäß der US-A-3 351 363 bietet fertigungstechnische Vorteile und eine gegen Querkräfte unempfindliche Teleskopverbindung insbesondere für den Fall, daß die muffenartige Aufweitung einen einstückig stoffschlüssigen Bestandteil des Außenrohres (Pos. 18) darstellt. Im Hinblick darauf, daß es sich bei Staubsauger-Saugrohren um Massenartikel handelt, wäre indes eine noch einfachere Bauform als die in der US-A-3 351 363 offenbarte wünschenswert. Zudem wird der Handhabungsbereich der bekannten Bauform als zu voluminös empfunden.The sleeve-like widening (item 81) according to US-A-3 351 363 offers advantages in terms of production technology and is insensitive to transverse forces Telescopic connection in particular in the event that the sleeve-like widening constitutes an integral integral part of the outer tube (item 18). In view of the fact that vacuum cleaner suction tubes are mass-produced items, an even simpler construction than the one disclosed in US Pat. No. 3,351,363 would be desirable. In addition, the handling area of the known design is felt to be too voluminous.

Ausgehend von dem teleskopierbaren Staubsauger-Saugrohr gemäß der US-A-3 351 363, liegt der Erfindung die Aufgabe zugrunde, das bekannte Staubsauger-Saugrohr unter Beibehaltung dessen fertigungs- und bedienungstechnischer Vorteile sowie dessen stabiler Bauweise weiter zu verbessern und hierbei zu einer besonders einfachen kompakten Bauform weiterzuentwickeln. Diese Aufgabe wird entsprechend dem Kennzeichenteil des Patentanspruchs 1 gelöst.Proceeding from the telescopic vacuum cleaner suction pipe according to US-A-3 351 363, the invention is based on the object of further improving the known vacuum cleaner suction pipe while maintaining its manufacturing and operating advantages and its stable construction, and in doing so to make it particularly simple further develop compact design. This object is achieved in accordance with the characterizing part of patent claim 1.

Das erfindungsgemäße Staubsauger-Saugrohr gestattet eine einfache kompakte Bauweise, weil praktisch alle wesentlichen Funktionsteile innerhalb der muffenartigen Aufweitung angeordnet sind. Insbesondere kann ein voluminöses Bedienteil (vgl. US-A-3 351 363, Fig. 13, Pos. 82) entfallen, denn die Erfindung kann sich mit einem die Aussparung der muffenförmigen Aufweitung durchgreifenden Bedienungsansatz begnügen. Dieser Bedienungsansatz braucht nur noch durch eine kleinbauende Handhabe ergänzt zu werden. Hierbei übernimmt in nicht naheliegender Weise der kreiszylindrische Kunststoff-Ringkörper zugleich die Führung des Niederhalters bzw. des Sperrschiebers.The vacuum cleaner suction pipe according to the invention allows a simple, compact design because practically all the essential functional parts are arranged within the sleeve-like widening. In particular, a voluminous control panel (cf. US-A-3 351 363, Fig. 13, item 82) can be omitted, because the invention can be used with a Satisfy the recess of the sleeve-shaped widening, the comprehensive operating approach. This operating approach only needs to be supplemented by a small handle. Here, in a manner that is not obvious, the circular cylindrical plastic ring body also takes over the guiding of the hold-down device or the locking slide.

Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen.Further advantages of the invention emerge from the subclaims.

In den Zeichnungen ist ein teleskopierbares Staubsauger-Saugrohr insgesamt mit der Bezugsziffer 10 bezeichnet. Das Saugrohr weist ein Innenrohr 11 und ein Außenrohr 12 auf. Das Außenrohr 12 bildet eine muffenartige Aufweitung 13. Innerhalb des zwischen Innenrohr-Außenmantelfläche 34 und Außenrohrinnenmantelfläche 33 befindlichen insgesamt mit 14 bezeichneten Freiraums ist ein im Querschnitt im wesentlichen kreisringförmiger Führungskörper 15 aus Kunststoff angeordnet. Im Führungskörper 15 aufgenommen ist jeweils ein entlang der Rohrlängsachse x translatorisch beweglicher Schieber 16 (Fig. 1 und 2,) 16a, (Fig. 3) sowie ein rotatorisch um die Rohrlängsachse x entlang der Umfangsrichtung u beweglicher Schieber 16b (Fig. 4 und 5).In the drawings, a telescopic vacuum cleaner suction tube is generally designated by the reference number 10. The suction pipe has an inner pipe 11 and an outer tube 12. The outer tube 12 forms a sleeve-like widening 13. Inside the overall space designated by 14 between the inner tube outer jacket surface 34 and the outer tube inner jacket surface 33, a guide body 15 made of plastic with an essentially circular cross section is arranged. Received in the guide body 15 is in each case a slide 16 (FIGS. 1 and 2,) 16a, (FIG. 3) which is translationally movable along the pipe longitudinal axis x (FIG. 3) and a slide 16b which is rotatable about the pipe longitudinal axis x along the circumferential direction u (FIGS. 4 and 5 ).

Jeder Schieber 16, 16a, 16b durchgreift die Außenrohrwandung 13 mit einem Betätigungsansatz 17 innerhalb einer Aussparung 18. Jeder Betätigungsansatz 17 wiederum trägt eine Handhabe 19.Each slide 16, 16a, 16b passes through the outer tube wall 13 with an actuation projection 17 within a recess 18. Each actuation projection 17 in turn carries a handle 19.

Jedes Innenrohr 11 weist eine Rastleiste 20 mit Rastausnehmungen 21 auf.Each inner tube 11 has a locking bar 20 with locking recesses 21.

Bei den dargestellten Ausführungsformen be stehen das Innenrohr 11 und Außenrohr 12 aus Stahlblech. Die Rastleiste 20 mit den Rastausnehmungen 21 ist als relativ schmaler leistenartiger Streifen in die Innenrohrwandung 22 eingeprägt. Die Einprägung ist hierbei derart, daß jede Rastausnehmung 21 von der jeweils benachbarten Rastausnehmung 21 über einen unverformten kreiszylindrischen Rohrwandbereich 23 distanziert ist.In the illustrated embodiments, the inner tube 11 and outer tube 12 are made of sheet steel. The locking bar 20 with the locking recesses 21 is stamped into the inner tube wall 22 as a relatively narrow strip-like strip. The embossing is in this case such that each latching recess 21 is distanced from the respectively adjacent latching recess 21 via an undeformed circular cylindrical tube wall region 23.

Jede Rastausnehmung 21 weist an einer axialen Endseite eine sich spitzwinklig geneigt zur Rohrlängsachse x erstrekkende Gleitflanke 24 für einen walzenartigen Rastkörper 25 (Fig. 1 und 2), für einen stegartigen Rastkörper 25a (Fig. 3) bzw. für einen Kugel-Rastkörper 25b (Fig. 4 und 5) auf.Each recess 21 has an axial end side which is inclined at an acute angle to the longitudinal axis of the tube x extending sliding flank 24 for a roller-like locking body 25 (FIGS. 1 and 2), for a web-like locking body 25a (FIG. 3) or for a ball locking body 25b (FIGS. 4 and 5).

An der anderen axialen Endseite einer jeden Rastausnehmung 21 ist mit einem relativ kleinen Krümmungsradius eine Sperr- bzw. Hemmflanke 26 ausgebildet. Und zwar weist eine jede Rastausnehmung 21 an ihrer zum Saugvorsatz (der Saugvorsatz ist nicht dargestellt, aber mit S und einem Pfeil angedeutet) wie zum Beispiel Saugbürste oder Saugdüse, weisenden axialen Endseite die gekrümmte Sperr- bzw. Hemmflanke 26 auf.On the other axial end side of each locking recess 21, a locking or inhibiting flank 26 is formed with a relatively small radius of curvature. In fact, each latching recess 21 on its axial end side facing the suction attachment (the suction attachment is not shown, but indicated with an S and an arrow), such as a suction brush or suction nozzle, has the curved locking or inhibiting flank 26.

Die jeweiligen Längsachsen der für längliche Rastkörper 25, 25a bestimmten Rastausnehmungen 21 (Fig. 1-3) erstrecken sich sekantial zum Körper des Innenrohrs 11, dessen Querschnitt kreiszylindrisch ist.The respective longitudinal axes of the latching recesses 21 (FIGS. 1-3) intended for elongated latching bodies 25, 25a extend secantially to the body of the inner tube 11, the cross section of which is circular-cylindrical.

Die Rastausnehmungen 21 entsprechend den Fig. 4 und 5 sind, jedenfalls im Querschnitt gemäß Fig. 5, im wesentlichen kugelkalottenförmig ausgebildet, während der zugehörige Rastkörper 25b selbst - wie bereits vorerwähnt - Kugelgestalt aufweist.The latching recesses 21 corresponding to FIGS. 4 and 5 are, at least in cross section according to FIG. 5, essentially spherical in shape, while the associated latching body 25b itself - as already mentioned - has a spherical shape.

Allen dargestellten Ausführungsformen entsprechend den Fig. 1-5 ist als wesentliches Merkmal gemeinsam, daß Schieber (bzw. Niederhalter) 16, 16a, 16b und zugehörige Rastkörper 25, 25a, 25b gesonderte Bauteile bilden. Während des Sperrzustandes (Fig. 1 sowie Fig. 3-5) hält der jeweilige Schieber 16, 16a, 16b den jeweiligen Rastkörper 25, 25a, 25b zwangsweise innerhalb einer ausgewählten Rastausnehmung 21, so daß Innenrohr 11 und Außenrohr 12 unverschieblich zueinander gehalten sind.All of the illustrated embodiments corresponding to FIGS. 1-5 have in common as an essential feature that slide (or hold-down device) 16, 16a, 16b and associated latching bodies 25, 25a, 25b form separate components. During the locked state (FIGS. 1 and 3-5), the respective slide 16, 16a, 16b forcibly holds the respective latching body 25, 25a, 25b within a selected latching recess 21, so that the inner tube 11 and outer tube 12 are held immovably relative to one another.

Falls jedoch der Schieber 16, 16a, 16b in Richtung o verschoben wird, öffnet der Schieber 16, 16a, 16b die Verbindung zum Freiraum 14, so daß der Rastkörper 25, 25a, 25b in der Lage ist, aus der Rastausnehmung 21 herauszugleiten (d.h., die beiden Teleskoprohre 11, 12 zu entkupplen), sobald eine Relativbewegung der beiden Teleskoprohre 11, 12 zueinander eingeleitet wird. In jedem Falle weist der Rastkörper 25, 25a, 25b eine relativ geringe Masse auf, so daß eine leichtgängiger Rastvorgang, also auch eine leichtgängige Verschieblichkeit der beiden Rohre 11, 12 zueinander, gewährleistet ist.However, if the slider 16, 16a, 16b is moved in the direction o, the slider 16, 16a, 16b opens the connection to the free space 14, so that the latching body 25, 25a, 25b is able to slide out of the latching recess 21 (ie to decouple the two telescopic tubes 11, 12) as soon as a relative movement of the two telescopic tubes 11, 12 to one another is initiated. In any case, the latching body 25, 25a, 25b has a relatively small mass, so that a smooth-running latching process, that is to say also a smooth movement of the two tubes 11, 12 with respect to one another, is ensured.

Die Funktion der einzelnen Ausführungsformen ist folgende:
   Wie aus Fig. 1 ersichtlich, befindet sich der walzenförmige Rastkörper 25 in einer Rastausnehmung 21 und wird dort mittels einer Sperrnase 27 des Schiebers 16 niedergehalten.The function of the individual embodiments is as follows:
As can be seen from FIG. 1, the roller-shaped latching body 25 is located in a latching recess 21 and is held down there by means of a locking lug 27 of the slide 16.

Sobald der Schieber 16 entgegen der Rückstellkraft einer lediglich gestrichelt eingezeichneten Schraubendruckfeder 28 betätigt wird, ergibt sich der Betriebszustand gemäß Fig. 2: Die Sperrnase 27 ist zurückgezogen, das Innenrohr 11 kann in Zugrichtung z nach links vom Außenrohr 12 weggezogen werden, wobei der walzenförmige Rastkörper 25 über jede Gleitflanke 24 völlig ungehindert hinweggleiten kann. Auch ein Ineinanderschieben der Rohrverbindung 10 in Druckrichtung d ist im dargestellten Zustand gemäß Fig. 2 möglich, da die Sperr- bzw. Hemmflanken 26 so ausgebildet sind, daß sie gerade noch ein Herausgleiten des jeweiligen Rastkörpers 25, 25a, 25b während der Verstellbewegung gestatten. Die Sperr- bzw. Hemmflanken 26 dienen einerseits einer während der Verstellbewegung fühl- bzw. hörbaren Rastmarkierung und bieten andererseits eine zusätzliche Sicherung der Sperrstellung (Fig. 1, Fig. 3 bis 5) auch für den Fall, daß die Druckkraft in Richtung d (starkes Anstoßen des Saugvorsatzes S gegen ein Hindernis während der Saugarbeit) relativ groß sein sollte. Auch ist es beim Ausführungsbeispiel gemäß Fig. 1 so, daß bei Auftreten einer relativ großen Kraft in Richtung d eine anfängliche Abrollbewegung des Walzenkörpers 25 eine Bewegung der Sperrnase 27 in Richtung z bzw. g, also eine zusätzliche Sicherung der Sperrstellung, bewirkt. Insoweit hat hier der Walzenkörper 25 etwa die Funktion eines sich zwischen zwei Zahnstangen abwälzenden Ritzels.As soon as the slide 16 is actuated against the restoring force of a helical compression spring 28, which is only shown in broken lines, the result is 2: The locking lug 27 is retracted, the inner tube 11 can be pulled away from the outer tube 12 in the pulling direction z to the left, the roller-shaped latching body 25 being able to slide completely freely over each sliding flank 24. Pushing the pipe connection 10 into one another in the pressure direction d is also possible in the state shown in FIG. 2, since the locking or inhibiting flanks 26 are designed such that they just allow the respective latching body 25, 25a, 25b to slide out during the adjustment movement. The locking or inhibiting flanks 26 serve, on the one hand, for a latching mark that can be felt or heard during the adjustment movement and, on the other hand, offer additional securing of the locking position (FIGS. 1, 3 to 5) also in the event that the pressure force in the direction d ( strong impact of the suction attachment S against an obstacle during suction work) should be relatively large. It is also the case in the exemplary embodiment according to FIG. 1 that when a relatively large force occurs in the direction d, an initial rolling movement of the roller body 25 causes a movement of the locking lug 27 in the direction z or g, that is to say an additional securing of the locking position. In this respect, the roller body 25 has approximately the function of a pinion rolling between two racks.

Sobald sich der walzenförmige Rastkörper 25 gemäß Fig. 2 wieder im Tiefsten einer bestimmten Rastausnehmung 21 befindet, bewegt sich der Schieber 16 nach Bestätigungsentlastung unter der Wirkung der Schraubendruckfeder 28 in Schließrichtung g. Es ist noch wichtig zu erwähnen, daß eine Mitnahme bzw. Positionierung eines jeden Rastkörpers 25, 25a, 25b etwa nach Art eines Kugelkäfigs mittels einer schieberseitigen Öffnung 29 erfolgt.As soon as the roller-shaped latching body 25 according to FIG. 2 is again in the deepest of a certain latching recess 21, the slide moves 16 after confirmation relief under the action of the helical compression spring 28 in the closing direction g. It is also important to mention that each latching body 25, 25a, 25b is carried along or positioned approximately in the manner of a ball cage by means of an opening 29 on the slide side.

Beim Ausführungsbeispiel gemäß Fig. 3 ist die Funktion ähnlich wie beim Ausführungsbeispiel gemäß den Fig. 1 und 2. Beim Ausführungsbeispiel gemäß Fig. 3 ist der stegartige Rastkörper 25a Bestandteil eines insgesamt mit 30 bezeichneten Rechtecksbügels bzw. -rahmens aus Draht. Der dem Verriegelungssteg 25a abgewandte Quersteg 31 des Bügels 30 ist innerhalb eines schieberseitigen Langloches 32 aufgenommen. Es ist vorstellbar, daß das Langloch 32 eine Verschiebung des Schiebers 16a in Richtung o gestattet, so daß die Sperrnase 27 den Zugang des Rastkörpers 25a zum Freiraum 14 herstellen kann, um den Verriegelungszustand, wie er in Fig. 3 dargestellt ist, aufzulösen.In the exemplary embodiment according to FIG. 3, the function is similar to that in the exemplary embodiment according to FIGS. 1 and 2. In the exemplary embodiment according to FIG. 3, the web-like latching body 25a is part of a rectangular bracket or frame made of wire, designated overall by 30. The transverse web 31 of the bracket 30 facing away from the locking web 25a is accommodated within an elongated hole 32 on the slide side. It is conceivable that the elongated hole 32 allows the slide 16a to be displaced in the direction o, so that the locking lug 27 can establish the access of the latching body 25a to the free space 14 in order to release the locking state, as shown in FIG. 3.

Die Funktion der Ausführungsform gemäß den Fig. 4 und 5 ist grundsätzlich vergleichbar mit den Ausführungsformen gemäß den Fig. 1 bis 3, mit dem Unterschied, daß die Betätigung des Schiebers 16b nicht translatorisch in Richtung der Rohrlängsache x, sondern vielmehr rotatorisch um die Rohrlängsachse x herum entsprechend den in Fig. 5 eingetragenen Pfeilen o in Öffnungsrichtung und g in Schließrichtung erfolgt. Auch bei diesem Ausführungsbeispiel (Fig. 5) ist eine Sperrnase 27 zu erkennen.The function of the embodiment according to FIGS. 4 and 5 is fundamentally comparable to the embodiments according to FIGS. 1 to 3, with the difference that the actuation of the slide 16b is not translatory in the direction of the longitudinal pipe thing x, but rather rotatory about the longitudinal pipe axis x around in accordance with the arrows in Fig. 5 o in the opening direction and g in the closing direction. Also in this embodiment (Fig. 5) a locking lug 27 can be seen.

Im übrigen ist doch denkbar, daß die Anordnung 16, 16a, 16b, 25, 25a, 25b durch eine an sich bekannte Kugelrast ersetzbar wäre. Hierbei könnte die Handhabe 19 beibehalten werden oder sogar entfallen. Im letzteren Falle, müßte die Stärke der Rastkraft durch die Rückstellkraft einer nicht eingezeichneten Kugelrast-Feder, welche in diesem Falle den Niederhalter darstellen würde, variiert werden. Eine ähnliche Ausführungsform wäre auch im Zusammenhang mit Fig. 3 denkbar. Dort könnte der Bügel 30 mit seinen beiden Längsschenkeln innerhalb des Freiraums 14 zwischen Außenrohr-Innenmantelfläche 33 und Innenrohr-Außenmantelfläche 34 innerhalb des Führungskörpers 15 translatorisch geführt und entgegen der Rückstellkraft einer oder zweier nicht dargestellter Federn (Niederhalter) aus den Rastausnehmungen 21 ausrastbar sein. Bei dieser nicht dargestellten Ausführungsform würden der Rastkörper 25a und die korrelierenden Rastausnehmungen 21 nicht - wie in Fig. 3 eingetragen - oben sondern vielmehr diametral gegenüberliegend an der unteren Seite des Innenrohres 11 angeordnet sein. Die sickenartige Axialnut 35 wäre sodann - nicht wie in Fig. 3 dargestellt - unten, sondern vielmehr diametral gegenüberliegend oben vorgesehen.Otherwise, it is conceivable that the arrangement 16, 16a, 16b, 25, 25a, 25b could be replaced by a ball catch known per se. Here, the handle 19 could be retained or even omitted. In the latter case, the strength of the detent force would have to be varied by the restoring force of a ball detent spring, not shown, which would represent the hold-down device in this case. A similar embodiment would also be conceivable in connection with FIG. 3. There, the bracket 30 could be guided with its two longitudinal legs within the free space 14 between the outer tube inner jacket surface 33 and the inner tube outer jacket surface 34 within the guide body 15 and against the restoring force of one or two springs (hold-down device), not shown, can be disengaged from the latching recesses 21. In this embodiment, which is not shown, the latching body 25a and the correlating latching recesses 21 would not be arranged at the top — as shown in FIG. 3 — but rather diametrically opposite on the lower side of the inner tube 11. The bead-like axial groove 35 would then - not as shown in Fig. 3 - provided below, but rather diametrically opposite at the top.

Eine Verdrehsicherung zwischen Innenrohr 11 und Außenrohr 12 kommt wie folgt zustande: Der am Außenrohr 12 innerhalb der Aufweitung 13 in nicht näher dargestellter Weise (beispielsweise durch Klebung) drehgesicherte Führungskörper 15 greift (vgl. Fig. 5) mit einer Axialfeder 36 in die innenrohrseitig vorgesehene axiale Längssicke 35 ein. Zugleich wird hier ein Fehlluft erzeugender Luftabschluß erreicht. Die Anordnung ist hierbei im übrigen so getroffen, daß der vordere äußere Bereich des Führungskörpers 15 einen unverformten Rohrbereich 23 übergreift, wenn sich die Rastkörper 25, 25a, 25b in einer Rastausnehmung 21 befinden.An anti-rotation device between the inner tube 11 and outer tube 12 comes about as follows: The on Outer tube 12 within the widening 13 in a manner not shown in more detail (for example by gluing), rotationally secured guide body 15 engages (see FIG. 5) with an axial spring 36 in the axial longitudinal bead 35 provided on the inner tube side. At the same time, an air seal generating incorrect air is achieved here. The arrangement is otherwise such that the front outer region of the guide body 15 engages over an undeformed tube region 23 when the latching bodies 25, 25a, 25b are located in a latching recess 21.

Die Erfindung sieht alternativ auch vor, Axialnut 35 und Rastausnehmungen 21 zu überlagern. So könnten die kugelförmigen Rastausnehmungen 21 gemäß Fig. 4 und 5 im Tiefsten einer um 180° umfangsversetzten Axialnut 35 (auch die Feder 36 wäre dann versetzt) eingeprägt sein.Alternatively, the invention also provides for axial groove 35 and latching recesses 21 to be superimposed. The spherical locking recesses 21 according to FIGS. 4 and 5 could be embossed in the deepest of an axial groove 35 offset circumferentially by 180 ° (the spring 36 would then also be offset).
