Description

Die Erfindung betrifft ein teleskopierbares Staubsauger-Saugrohr entsprechend dem Oberbegriff des Anspruchs 1. Ein solches Staubsauger-Saugrohr ist durch die DE 40 17 721 A1 bekanntgeworden.The invention relates to a telescopic vacuum cleaner suction pipe according to the preamble of the claim 1. Such a vacuum cleaner suction pipe is through DE 40 17 721 A1 has become known.

Das bekannte Staubsauger-Saugrohr hat sich insbesondere wegen minimierter Saugverluste als vorteilhaft erwiesen. Dieses wird dadurch erreicht, daß der innerhalb der Teleskopfuge ohnehin vorhandene Spielraum zwischen der Außenmantelfläche des Innenrohres und der Innenmantelfläche des Außenrohres zur Aufnahme der aus Kunststoff bestehenden Dichtungshülse genutzt wird.The well-known vacuum cleaner suction pipe has in particular because of minimized suction losses as advantageous proved. This is achieved in that the the telescopic eye already existing space between the outer surface of the inner tube and the inner surface the outer tube to accommodate the Plastic existing sealing sleeve is used.

Zur Positionierung und Befestigung der Dichtungshülse auf der Außenmantelfläche des Innenrohres weist die bekannte Dichtungshülse als hülsenseitiges Rastmittel radial nach innen ragende, in Radialrichtung federnd nachgiebige Rastnasen auf.For positioning and fastening the sealing sleeve points on the outer surface of the inner tube the known sealing sleeve as a locking means on the sleeve side protruding radially inwards, resilient in the radial direction flexible latches.

Als rohrseitige Gegenrastmittel weist das Innenrohr des bekannten Staubsauger-Saugrohres die Innenrohrwandung durchsetzende Rastaussparungen (Durchbrüche) auf, in welche die hülsenseitigen Rastnasen einrasten.The inner tube has the counter-locking means on the tube side of the known vacuum cleaner suction tube, the inner tube wall penetrating recesses (openings) in which the sleeve-side locking lugs engage.

Obwohl sich das Staubsauger-Saugrohr gemäß der DE 40 17 721 A1 im großen Umfang in der Praxis bewährt hat, wird die bekannte Anordnung im Hinblick auf ihre Montagehandhabung als verbesserungsbedürftig empfunden. Although the vacuum cleaner suction pipe according to the DE 40 17 721 A1 has proven itself in practice on a large scale has, the known arrangement in terms of their Assembly handling perceived as in need of improvement.

Eine bei der bekannten Anordnung an sich vorteilhafte Montageweise besteht darin, die Dichtungshülse mit ihrem ihrer Dichtlippe abgewandten äußeren Axialbereich voran über die innere Stirnfläche des Innenrohres hinweg auf deren Aussenmantelfläche axial so weit aufzuschieben, bis die hülsenseitigen Rastnasen in die innenrohrseitigen Durchbrüche eingreifen.An advantageous per se in the known arrangement The way of assembly consists of the sealing sleeve with its outer axial area facing away from its sealing lip ahead over the inner face of the inner tube away axially on their outer surface to be pushed open far until the locking lugs on the sleeve side engage the openings on the inner tube side.

Weil die Durchbrüche Stanzaussparungen mit nicht immer vermeidbaren scharfkantigen Rändern bilden, ist es bei ungünstiger Montagehandhabung nicht auszuschließen, daß die Rastnasen der wegen einer guten Dichtwirkung aus verhältnismäßig weichem Kunststoff bestehenden Dichtungshülse abgeschabt werden, so daß eine einwandfreie Befestigung der Dichtungshülse auf dem Innenrohr nicht immer gewährleistet ist.Because the breakthroughs with punching notches always form avoidable sharp-edged edges it cannot be excluded in the case of unfavorable assembly handling, that the locking lugs because of a good one Sealing effect made of relatively soft plastic Sealing sleeve are scraped off so that a perfect attachment of the sealing sleeve to the inner tube is not always guaranteed.

Ausgehend von dem durch die DE 40 17 721 A1 bekannten teleskopierbaren Staubsauger-Saugrohr, liegt der Erfindung die Aufgabe zugrunde, die Montierbarkeit der bekannten Dichtungshülse zu verbessern und, gegebenenfalls damit einhergehend, den Kostenaufwand für die Montage der Dichtungshülse zu verringern.Starting from what is known from DE 40 17 721 A1 telescopic vacuum cleaner suction pipe the invention has the object of being mountable to improve the known sealing sleeve and, if necessary associated with this, the cost of to reduce the assembly of the sealing sleeve.

Entsprechend der Erfindung wird diese Aufgabe dadurch gelöst, daß dem Innenrohr als Gegenrastmittel mindestens ein in den Zwischenraum zwischen Innen- und Außenrohr hineinragender Vorsprung zugeordnet ist, daß der Vorsprung an der Wand des Innenrohres festgelegt ist, und daß das hülsenseitige Rastmittel von einer an der Innenmantelfläche der Hülse offenen, das Gegenrastmittel aufnehmenden, Aussparung gebildet ist, welche einen Durchbruch in der Wand der Dichtungshülse bildet. According to the invention, this object solved that the inner tube as a counter-locking means at least one in the space between interior and Outer tube protruding projection is assigned that the projection is fixed on the wall of the inner tube is, and that the sleeve-side locking means from one the inner surface of the sleeve open, the counter-locking means receiving recess is formed, which a Breakthrough in the wall of the sealing sleeve forms.

Der besondere Vorteil der erfindungsgemäßen Anordnung besteht darin, daß sich der in den Zwischenraum zwischen Innen- und Außenrohr hineinragende innenrohrseitige Vorsprung - im Unterschied zu der die Wandung des Innenrohres durchsetzenden Rastaussparung gemäß der DE 40 17 721 A1 - mit einfachen Mitteln von Haus aus derart ausbilden läßt, daß er bei der Aufschiebemontage der Dichtungshülse die Innenkontur der hülsenseitigen Aussparung nicht beschädigen kann.The particular advantage of the arrangement according to the invention is that it is in the space inner tube-side protruding between inner and outer tube Head start - in contrast to the wall of the inner tube penetrating recess according to the DE 40 17 721 A1 - with simple means from the start trained in such a way that it can be mounted on the slide the sealing sleeve the inner contour of the sleeve Can not damage the recess.

Ein Aspekt der Erfindung besteht in diesem Zusammenhang auch darin, erkannt zu haben, daß es vorteilhaft ist, die Aussparung dem weicheren Werkstoff der Werkstoffpaarung, also der Dichtungshülse zuzuordnen, und das rohrseitige Gegenrastmittel, den Vorsprung also, aus dem härteren Werkstoff des Innenrohres zu bilden.One aspect of the invention is in this context also in having recognized that it is beneficial is the recess the softer material of the Material pairing, i.e. to assign the sealing sleeve, and the tube-side counter-locking means, the projection So, from the harder material of the inner tube form.

Zweckmäßig sieht die Erfindung vor, daß der Vorsprung unlösbar fest mit der Wand des Innenrohres verbunden ist, wobei diese Verbindung zweckmäßig aus einer stoffschlüssigen Verbindung des Vorsprungs mit der Wand des Innenrohres bestehen kann.The invention expediently provides that the projection permanently attached to the wall of the inner tube is, this connection expediently from a cohesive connection of the projection with the wall of the inner tube can exist.

In weiterer Ausgestaltung der Erfindung ist bei einem aus Metall bestehenden Innenrohr der Vorsprung eine vom Rohrinnenraum nach außen vorragende, bleibend verformte Prägestelle. Die Herstellung einer derartigen Prägestelle ist dann besonders günstig, wenn das Innenrohr ohnehin mindestens eine als Ausziehstopp für das Außenrohr bestimmte, aus der Außenmantelfläche des Innenrohres vorragende Prägestelle aufweist.In a further embodiment of the invention an inner tube made of metal, the projection one that protrudes outward from the pipe interior and remains deformed embossing point. The manufacture of such Embossing is particularly favorable if the inner tube anyway at least one as a pull-out stop for that Outer tube determined from the outer surface of the inner tube has outstanding embossing.

In einem solchen Falle braucht das Prägewerkzeug zur Herstellung des Ausziehstopps nur um ein geringes Maß axial versetzt zu werden, um das rohrseitige Gegenrastmittel, nämlich den erfindungsgemäßen Vorsprung, zu fertigen. Es ist ebenfalls möglich, mit einem Doppel-Prägewerkzeug sowohl den Ausziehstopp als auch den erfindungsgemäßen Vorsprung, zeitlich zusammengefaßt, in einem Arbeitsvorgang zu fertigen.In such a case, the stamping tool needs to make the pull-out stop just a little Dimension to be axially offset to the tube-side counter-locking means, namely the projection according to the invention finished. It is also possible to use a double stamping tool both the pull-out stop and the one according to the invention Head start, summarized in time, in to manufacture one operation.

Eine erfindungsgemäße Ausführungsvariante ist dadurch gekennzeichnet, daß die hülsenseitige Aussparung an ihrer der inneren Stirnfläche des Innenrohres abgewandten Seite mindestens eine quer oder geneigt zur Mantellinie der Außenmantelfläche des Innenrohres verlaufende Sperrfläche bildet, welche eine der inneren Stirnfläche des Innenrohres abgewandte korrespondierende Gegensperrfläche des Vorsprungs hintergreift.This is an embodiment variant according to the invention characterized in that the sleeve-side recess on their inner end face facing away from the inner tube Side at least one transverse or inclined to Surface line of the outer circumferential surface of the inner tube Barrier area forms which one of the inner Corresponding end face of the inner tube facing away Counter locking surface of the projection engages behind.

In weiterer Ausgestaltung der Erfindung wird eine besonders schonende Aufschiebemontage der Dichtungshülse dadurch erzielt, daß der Vorsprung eine in Richtung zur inneren Stirnfläche des Innenrohres bis zu dessen Außenmantelfläche hin in Rohrlängsrichtung geschmeidig abfallende Gleitfläche bildet. Dabei kann die Gleitfläche eine buckel- oder rampenartig abfallende Fläche darstellen.In a further embodiment of the invention particularly gentle slide-on installation of the sealing sleeve achieved in that the projection one in the direction to the inner face of the inner tube up to the outer surface of the pipe is supple in the longitudinal direction of the pipe sloping sliding surface forms. The A hump or ramp-like slope Represent area.

Obwohl die Gestalt der Außenkontur des Vorsprungs alle möglichen Formen annehmen kann, hat die Erfindung eine vorteilhafte Ausführungsvariante derart ausgebildet, daß die Aus-senkontur des Vorsprungs im Übergang zur Außenmantelfläche des Innenrohres etwa dreieckoder etwa trapezförmig ist, wobei die zur inneren Stirnfläche des Innenrohres weisenden Dreieck- oder Trapezschenkel der Außenkontur die Gleitfläche begrenzen und die von der inneren Stirnfläche abgewandte Basis der Dreieck-Kontur oder Trapez-Kontur die Gegensperrfläche begrenzt.Although the shape of the outer contour of the projection The invention has all possible forms an advantageous embodiment is designed such that the outer contour of the projection in the transition to the outer circumferential surface of the inner tube approximately triangular or is approximately trapezoidal, with the inner End face of the inner tube pointing triangle or Trapezoidal legs of the outer contour limit the sliding surface and the base facing away from the inner face the triangle contour or trapezoidal contour the counter-blocking surface limited.

Eine Weiterbildung entsprechend der Erfindung besteht darin, daß die Innenkontur der das hülsenseitige Rastmittel bildenden Aussparung an die Außenkontur des Vorsprungs angepaßt ist.A further development according to the invention exists in that the inner contour of the sleeve side Notch forming recess on the outer contour of the Projection is adjusted.

Obwohl es grundsätzlich realisierbar ist, die das hülsenseitige Rastmittel bildende Aussparung als Einsenkung in der Innenmantelfläche des Hülsenkörpers vorzusehen, sieht es die Erfindung der einfachen Herstellbarkeit halber als besonders günstig an, eine solche Aussparung als Durchbruch in der Wand der Dichtungshülse auszubilden. Zweckmäßig ist dabei die radiale Höhe des Vorsprungs gleich oder geringer als die Wandstärke der Dichtungshülse.Although it is basically feasible that the recess on the sleeve side forming a recess to be provided in the inner surface of the sleeve body, it sees the invention of ease of manufacture for the sake of being particularly cheap, such Cut-out as opening in the wall of the sealing sleeve train. The radial is expedient The height of the projection is equal to or less than the wall thickness the sealing sleeve.

Die bekannte Dichtungshülse gemäß der DE 40 17 721 A1 weist an ihrem inneren Ende einen radial nach innen vorragenden Stützring auf, welcher sich nach der Montage der Dichthülse gegen die innere Stirnfläche des Innenrohres anlegt und somit eine Aufschiebebegrenzung darstellt. The known sealing sleeve according to the DE 40 17 721 A1 has a radial at its inner end inward protruding support ring, which is after installing the sealing sleeve against the inner face of the inner tube and thus a deferral limitation represents.

Eine solche Aufschiebebegrenzung kann entweder unter Beibehaltung des bekannten Stützringes oder durch Ersatz des bekannten Stützringes erfindungsgemäß dadurch verwirklicht werden, daß die von der inneren Stirnfläche des Innenrohres abgewandte Stirnfläche der Dichtungshülse gegen mindestens einen in den Zwischenraum zwischen Innen- und Außenrohr hineinragenden, am Innenrohr festgelegten Stützanschlag stößt.Such a deferral limit can either while maintaining the known support ring or by Replacement of the known support ring according to the invention be realized by the inner Face of the inner tube facing away from the face Sealing sleeve against at least one in the space protruding between the inner and outer tube, on The inner tube is struck by the support stop.

Ein besonderer Vorteil ergibt sich dadurch, daß der Stütz-Anschlag eine vom Innenraum des Innenrohres nach außen vorragende, bleibend verformte Prägestelle ist, welche auch von dem bereits erwähnten Ausziehstopp gebildet sein kann.A particular advantage results from the fact that the support stop one from the interior of the inner tube protruding, permanently deformed embossing point which is also from the already mentioned pull-out stop can be formed.
