Abstract
Description
Staubsauger bestehen aus einer Unterdruck erzeugenden Einheit sowie einem flexiblen Saug-Schlauch mit einem steifen Rohrende und einer Saugdüse.vacuum cleaner consist of a vacuum generating unit and a flexible suction hose with a stiff pipe end and a suction nozzle.
Industrieelle Sauger können zudem Flüssigkeiten, bis hin zu pastösen Medien fördern. Diese Geräte empfindet der Verwender als sperrig, da der Saug-Schlauch nach der Verwendung nicht aufgewickelt werden kann.industry Elle Suckers can also carry liquids, right through to promote pasty media. This device feels the user as bulky, since the suction hose after use can not be wound up.
Üblich ist hingegen das aufrollbare Stromkabel, welches über eine Wickelvorrichtung im Inneren des Gerätes platzsparend gelagert wird.Common is, however, the roll-up power cable, which has a Winding device stored inside the device to save space becomes.

ist folgende Patentschrift:
Vorschlag:Suggestion:
Es wird hiermit vorgeschlagen, auch den Saugschlauch diverser Geräte zum Fördern von Medien aufrollbar zu gestalten.It is hereby proposed, also the suction hose of various devices to be able to be rolled up to convey media.
Zu diesem Zwecke muß die lichte innere Weite und die Stabilität des Schlauches reduziert werden, um an der Außen- oder Innen-Seite des Saugers platzsparend aufbewahrt zu werden. Ohne Reduzierung der lichten Weite könnte er nur auf einer Rolle mit einem so großen Radius aufgewickelt werden, die sich nicht in das Gehäuse eines handelsüblichen Saugers integrieren ließe.To For this purpose, the light inner width and the stability must the hose can be reduced to the outside or Inside of the teat to be stored to save space. Without Reducing the breadth of space he could only do on a roll be wound up with such a large radius, which is not in the housing of a commercial vacuum cleaner could integrate.
Lösung:Solution:
Wird die Wandung des Saugschlauches nach dem Entrollen/Herausziehen mit einem erhöhtem Hilfs-Druck beaufschlagt, so vergrößert sich der den für den Stofftransport nötige Querschnitt (hier Förderquerschnitt genannt). Der Querschnitt ist während des Förderns annähernd stabil, d. h. er knickt nicht ein, bzw. bleibt formstabil.Becomes the wall of the suction hose after unrolling / pulling out with an increased auxiliary pressure applied, so enlarged the necessary for the mass transport cross section (called here conveyor cross-section). The cross section is during of conveying nearly stable, d. H. he kinks not one, or remains dimensionally stable.
Der nötige Hilfsdruck ist abhängig vom Saugschlauch-Durchmesser, dem Durchmesser, der Geometrie und Anordnung der Hilfsdruck-Kanäle, sowie der verwendeten Materialien.Of the necessary auxiliary pressure depends on the suction hose diameter, the diameter, geometry and arrangement of auxiliary pressure channels, as well as the materials used.
Die Stabilität bisheriger Saugschläuche (d. h. die unveränderliche lichte innere Weite) wird in der Regel durch eine umlaufende (schraubenförmige) Drahtarmierung erreicht. Diese ist in die Schlauchwandung integriert und garantiert den offenen Förderquerschnitt, während im Schlauch ein Unterdruck herrscht.The Stability of previous suction hoses (i.e. invariable light inner width) is usually through achieved a circumferential (helical) wire reinforcement. This is integrated in the hose wall and guarantees the open Cross section, while in the hose a negative pressure prevails.
Diese Schläuche lassen sich nur auf große Radien aufwickeln. Würde ein solcher Schlauch hingegen mit Gewalt, unter Reduzierung seines Querschnittes, als auch Volumens aufgewickelt, so würde sich der Stützdraht zwangsläufig deformieren oder die Schlauchwandung überdehnen und ggf. reißen.These Hoses can be wound up only on large radii. Would such a hose, however, by force, under reduction of its cross section, as well as volume wound up, so would the support wire inevitably deform or overstretch the hose wall and tear if necessary.
Der erhöhte Hilfsdruck zur Stabilisierung des Förderquerschnittes wird wie folgt eingebracht.
- 1. durch Überdruck außerhalb oder mittig gelegen oder
- 2. innerhalb
- 1. by overpressure outside or centered or
- 2. within
Der Überdruck wird zweckmäßigerweise in eine oder mehrere Kammern längs- oder spiralförmig entlang der Längsachse des Schlauches geleitet, wodurch der Saugschlauch radial seinen Querschnitt vergrößert.The overpressure is suitably in one or more chambers longitudinally or spirally along the longitudinal axis led the hose, whereby the suction hose radially Cross-section enlarged.
Zur Gewährleistung leichter Entrollbarkeit, bei gleichzeitiger Befüllung mit dem Hilfsdruck wird zusätzlich vorgeschlagen, die Hilfsdruck-Kammern mit Rillen oder Erhebungen auf ihrer Innenseite zu versehen, die den Transport von Druckluft auch im zusammengerollten, oder geknickten Zustand ermöglichen.to Ensuring easy usability while at the same time Filling with the auxiliary pressure is additionally suggested the auxiliary pressure chambers with grooves or protrusions on their inside to provide the transport of compressed air even when rolled up, or kinked condition.
Verhindert werden soll hierdurch das Phänomen, des geknickten Gartenschlauches, der mit Wasser befüllt, allein durch Knicken abgesperrt werden kann. Dies ist nur möglich, da sich beim Knicken die Innen-Flächen des Schlauches bündig berühren und den Schlauch abdichten. Diese Kanäle hingegen behindern die vollständige gegenseitige Berührung der Innenflächen. Die Druckluft kann sich weiterhin ausbreiten und beim Entrollen den Schlauch entfalten und auf diese Weise seine innere Weite vergrößern.prevents This is to be the phenomenon of the kinked garden hose, filled with water, shut off solely by kinking can be. This is only possible because when kinking flush the inner surfaces of the hose and seal the hose. These channels, however, hinder the complete mutual contact of the inner surfaces. The compressed air can continue to spread and when unrolling unfold the tube and thus increase its inner width.
Wird der Hilfsdruck wird schon eingebracht, während sich der Saugschlauch noch im aufgerollten Zustand befindet, so breitet sich die Druckluft zu dem Ende des Schlauches aus, welches bereits entrollt wurde und der betroffene Querschnitt vergrößert sich.Becomes the auxiliary pressure is already introduced, while the Suction hose is still in the rolled up state, so spreads the compressed air to the end of the hose, which is already unrolled was increased and the affected cross section yourself.
Dies wird als besonders vorteilhaft angesehen, wenn mittels einer weiteren mechanischen Vorrichtung der gewickelte Schlauch abgerollt, bzw. aus dem Gehäuse herausgeschoben wird und sich gleichzeitig und selbsttätig entfaltet/expandiert.This is considered to be particularly advantageous if by means of another mechanical device of the wound hose unrolled, or is pushed out of the case and at the same time and automatically unfolded / expanded.
Wird genügend Druck eingebracht, so wird nicht nur der Querschnitt des Schlauches vergrößert, es wird auch die Knicksteifigkeit gegen Verbiegen um die Längsachse erhöht. Durch diese Eigenschaft ist der Saugschlauch auch als stabiles Saugrohr nutzbar.Becomes not enough pressure, so not only the cross section the hose increases, it also becomes the kink stiffness increased against bending about the longitudinal axis. By This feature is the suction hose as a stable suction tube available.
Wird an dessen Ende die Saugdüse angebracht, so erübrigt sich die weitere Verwendung eines Saugrohres aus einem unflexiblen Material oder wie üblich aus steckbaren Teleskopstäben.Becomes attached to the end of the suction nozzle, so unnecessary the further use of a suction tube of an inflexible Material or as usual from plug-in telescopic rods.
Es
versteht sich, dass die Materialien des Saugschlauches vorzugsweise
von hoher Zähigkeit sind, damit im Saug-Strom angesaugter
Partikel, Nadeln oder kleine Scherben die Wandung der druckbeaufschlagten
Hilfskanäle nicht zerstören können. Legende und weitere Erläuterungen
