Description
Flexibler Saugschlauch, insbesondere für Industrie-Staubsauger und Sauggebläse Die für Industrie-Staubsauger gebräuchlichen Saugschläuche, wie sie vor allem in Holzbearbeitungs- betrieben zum Absaugen von Hobel-, Bohr- und Sägespänen sowie Schleifstaub Verwendung finden, weisen bedeutend grösseren Durchmesser auf, als die im Hausgebrauch üblichen, mit Metallarmierung versehenen Saugschläuche. Der grössere Schlauch durchmesser sowie das grössere Vakuum bei In dustriestaubsaugern bedingen auch eine kräftigere Metallarmierung des Schlauches.
Eine solche Armie- rung ist nicht ohne Einfluss auf das Gewicht des Saugschlauches und macht ihn schwer und unhand lich für den Gebrauch.
Die vorliegende Erfindung betrifft nun einen flexiblen Saugschlauch, insbesondere für Industrie- Staubsauger, welcher sich von den bekannten Saug schläuchen dadurch unterscheidet, dass die äussere Hülle des Saugschlauches aus einem hermetisch dicht imprägnierten oder mit Kunststoffmasse beschichte ten, feinen Gewebe und die Armierung aus einem mit der Innenwand der Hülle fest verbundenen, den Schlauchdurchmesser versteifenden und in der Längs richtung des Schlauches nachgebenden metallfreien Gebilde besteht.
In der Zeichnung ist eine beispielsweise Aus führungsform des Erfindungsgegenstandes dargestellt, und zwar zeigt: Fig. 1 ein Teilstück des Saugschlauches, teilweise gebogen und teilweise im Längsschnitt, und Fig.2 einen Querschnitt nach der Linie II-II in Fig. 1.
Der dargestellte Saugschlauch weist eine äussere Hülle 1 aus einem mit einer Kunststoffmasse herme tisch dicht imprägnierten oder beschichteten feinen Gewebe auf. Als Armierung dienen Ringe 2 aus Kunststoff oder Pressstoff, welche koaxial und parallel zueinander, in gleichmässigen Abständen a voneinan- der in die schlauchförmige Hülle 1 eingesetzt und mit dieser unter Verwendung von Klebstoff oder der gleichen Bindemittel fest verbunden sind. Bei Ver wendung von Armierungsringen 2 aus thermoplasti schem Kunststoff, können diese durch Verschweissen mit der Hülle 1 verbunden werden.
Die Abstände zwischen den Ringen 2 erlauben das Biegen des Schlauches, wobei sich die Hülle 1 auf der Bogeninnenseite in den Zwischenräumen a zwischen den Ringen 2 in einwärts springende Fal ten f legen kann, wie dies in Fig. 1 ersichtlich ist.
Im dargestellten Fall bilden die Ringe Abschnitte von einem Kunststoffrohr, was der billigsten Her stellungsmethode für Ringe dieser Art entspricht.
Als äussere Hülle eignet sich besonders Stamoid (eingetragene Marke).
Flexible suction hose, especially for industrial vacuum cleaners and suction fans The suction hoses commonly used for industrial vacuum cleaners, as they are mainly used in woodworking companies for suctioning off planing, drilling and sawdust as well as grinding dust, have a significantly larger diameter than those in Common household use, metal armored suction hoses. The larger hose diameter and the larger vacuum in industrial vacuum cleaners also require a stronger metal reinforcement of the hose.
Such a reinforcement has an influence on the weight of the suction hose and makes it difficult and difficult to handle.
The present invention relates to a flexible suction hose, in particular for industrial vacuum cleaners, which differs from the known suction hoses in that the outer shell of the suction hose consists of a hermetically sealed impregnated or plastic mass coated fine fabric and the reinforcement from one with the inner wall of the sheath firmly connected, the tube diameter stiffening and yielding in the longitudinal direction of the tube, metal-free structure.
The drawing shows an example of an embodiment of the subject matter of the invention, namely: FIG. 1 shows a section of the suction hose, partially bent and partially in longitudinal section, and FIG. 2 shows a cross section along the line II-II in FIG. 1.
The suction hose shown has an outer shell 1 made of a fine fabric which is hermetically tightly impregnated or coated with a plastic compound. Rings 2 made of plastic or pressed material serve as reinforcement, which are inserted coaxially and parallel to one another, at regular intervals a from one another in the tubular casing 1 and are firmly connected to it using adhesive or the same binding agent. When using reinforcement rings 2 made of thermoplastic cal plastic, they can be connected to the shell 1 by welding.
The distances between the rings 2 allow the hose to be bent, the envelope 1 being able to lay on the inside of the arch in the spaces a between the rings 2 in inwardly jumping Fal th f, as can be seen in FIG.
In the case shown, the rings form sections of a plastic pipe, which corresponds to the cheapest method for making rings of this type.
Stamoid (registered trademark) is particularly suitable as an outer cover.
