Abstract

The flexible tube (1) for a vacuum cleaner or dust extraction equipment, also carries an electrical cable (3) with coiled conductors. The tube incorporates a channel (2) inside which the cable is supported, the whole being enclosed by an outer tube (4). In another form, the inner tube has a flat along it, being approximately D-shaped. Inside the space between this surface and the outer tube is a shallower D-section of plastics foam, with the cable embedded in it. Instead of a cable, a small tube may be housed in the space.

Description

"Kunststeffschlauch" "Synthetic hose"

Die Erfindung betrifft einen Kunststeffschlauch mit in zeiner Längzrichtung angeordnetem Kabel oder dünnem Schlauch.The invention relates to a plastic hose with a longitudinal direction arranged cable or thin hose.

Selche Schläuche finden z. B. Verwendung bei elektrischen Geräten, z. B. Staubsaugern, we es netwendig ist, parallel zum Staubsaugerschlauch elektrische Leitungen zu führen.Such hoses can be found e.g. B. Use in electrical devices, z. B. vacuum cleaners, we it is necessary, parallel to the vacuum cleaner hose electrical To lead lines.

Derartige Schläuche sind in verschiedenen Ausführungen bekannt.Such hoses are known in various designs.

8. zeigt z. B. die DDR-Patentschrift 87 344 einen Kunststoffschlauch mit elektrischem Leiter, welcher aus einem in die Wandung eingearbeitete Kupferdraht besteht.8. shows e.g. B. the GDR patent specification 87 344 a plastic hose with electrical conductor, which consists of a incorporated into the wall Made of copper wire.

Eine solche Ausfuehrung hat eine gentigend. Wandstärke des Schlauchmaterials zur Voraussetzung.Such an execution is sufficient. Wall thickness of the hose material a prerequisite.

In diesen Fällen ist es jedoch erwünscht, die Wandstärke solcher Schläuche möglichst gering zu halten.In these cases, however, it is desirable to increase the wall thickness of such hoses to be kept as low as possible.

In diese Fall besteht der Schlauch aus leicht blegsee Material und bildet zweckmäßig eine selbsttragende Einheit.In this case, the hose is made of a slightly blegsee material and expediently forms a self-supporting unit.

Bei einem biegsamen Schlauch, insbesondere für Staubsauger nach der DE-OS 27 05 335 dienen die Nuten des Schlauches zur Aufnahme elektrischer Leiter. Zu diesei Zweck sind die Nuten als schraubengangförmige nach außen offene Schwalbenschwanznuten ausgebildet. Diese Ausftflirung bedingt eine sehr große Länge des elektrischein Leiters.With a flexible hose, especially for vacuum cleaners after the DE-OS 27 05 335 serve the grooves of the hose to accommodate electrical conductors. For this purpose, the grooves are designed as helical, outwardly open dovetail grooves educated. This design requires a very large length of the electrical input Head.

Die Erfindung bezweckt die Schaffung eines Schlauches der erwähnten Gattung, bei welche der Kanal zur AuS-nahae des Kabels durch Verformung z. B. Pressen oder Wärmeverformung hergestellt werden kann, wobei die Nachteile der verbekannten Ausführung vermieden werden, nämlich eine gewichtsaäßig schwere Ausführung, eine ungeneigende Flexibilität, eine optisch unschöne Ausfttrung sowie die Gefahr des Hängenbleibens.The invention aims to provide a hose of the type mentioned Type in which the channel to the AuS-nahae of the cable by deformation z. B. Pressing or thermoforming can be produced, the disadvantages of the known Execution can be avoided, namely a weighty heavy one Execution, an inadequate flexibility, an optically unsightly finish as well the risk of getting stuck.

Bei eine Kunststoffschlauch mit in seiner Längsrichtung angeordnete Kabel oder dünnem Schlauch wird der Erfindungszweck dadurch erreicht, daß der Schlauchquerschnitt von der Kreisform an der Stelle nach innen abweicht, wo das Kabel oder der dünne Schlauch auf seiner Außenseite liegen soll.In the case of a plastic tube with arranged in its longitudinal direction Cable or thin hose, the purpose of the invention is achieved in that the hose cross-section deviates inward from the circular shape at the point where the cable or the thin one Hose should lie on its outside.

Erfindungsgemäß bildet die Abweichung eine äußere Längsvertiefung (Rinne) oder eine äußere Abflachung.According to the invention, the deviation forms an outer longitudinal depression (Gutter) or an external flat.

Nach einen weiteren Merkmal der Erfindung kann das Kabel oder der dünne Schlauch in einen Schauistoffsegient liegen. Dieses Schaumstoffsegment wird dann in der Rinne oder auf der Abflachung angeordnet.According to a further feature of the invention, the cable or the thin tube lying in a show fabric sliver. This foam segment will then arranged in the channel or on the flat.

Ein weiteres wesentliches Merkmal der Erfindung liegt darin, daß der Innenschlauch mit des an seiner Außenseite liegenden Kabel oder dünne Schlauch von eine im Querschnitt kreisförmigen Schlauch ummantelt sind.Another essential feature of the invention is that the Inner tube with the cable lying on its outside or thin tube of a tube with a circular cross-section is sheathed.

In der Zeichnung sind zwei AusfUhrungen des Erfindung gegenstandes beispielsweise und schematisch sowie schaubildlich und teilweise in Schnitt dargestellt.In the drawing, two embodiments of the invention are the subject matter for example and schematically as well as graphically and partially shown in section.

Bei der Ausführungsform gemäß Fig. 1 weicht der Schlauchquerschnitt des Schlauches 1 nach innen ab und bildet eine Rinne 2 als äußere Längsvertiefung. In der Rinne liegt das ein- oder nehradrige Kabel 3.In the embodiment according to FIG. 1, the hose cross-section deviates of the hose 1 inwards and forms a channel 2 as an outer longitudinal recess. The single or multi-core cable 3 lies in the channel.

Das Kabel 3 kann auch durch einen dünnen Schlauch ersetzt werden.The cable 3 can also be replaced by a thin tube.

Der Innenschlauch 1 nit den an seiner Außenseite liegenden Kabel 3 oder dünne Schlauch ist von eine ii Querschnitt kreisförmigen Schlauch 4 ummantelt.The inner tube 1 with the cable 3 lying on its outside or thin hose is encased by a circular hose 4 in cross section.

Bei der Ausführung gemäß Fig. 2 bildet die Abweichung des Schlauchquerschnittes des Innenschlauches 1 eine äußere Abflachung 5. Das Kabel 6 oder ein dünner Schlauch liegen in eine Schaumstoffsegment 7. Dieses liegt suf der äußeren Abflachung 5. Der Innenschlauch 1 und das Schaumstoffsegment 7 sind von eine in Querschnitt kreisförmigen Schlauch 8 ummantelt.In the embodiment according to FIG. 2, the deviation of the hose cross-section forms of the inner tube 1 an outer flat 5. The cable 6 or a thin tube lie in a foam segment 7. This lies on the outer flat 5. The inner tube 1 and the foam segment 7 are circular in cross section Hose 8 sheathed.

Der Innenschlauch 1 kann in beliebiger Weise als glatter oder gerippter, extrudierter oder gewickelter sowie gogebenenfalls verstärkter Schlauch hergestellt werden.The inner tube 1 can be in any way as smooth or ribbed, extruded or wound as well as possibly reinforced hose manufactured will.

Das gleiche gilt ftir den äußeren Schlauch 4, welcher Jedoch zweckmäßig sehr dünnwandig ausgebildet wird und sich gegebenenfalls den gewählten Konturen des Innenschlauches 1 anpaßt.The same applies to the outer tube 4, which, however, is expedient is made very thin-walled and, if necessary, the selected contours of the inner tube 1 adapts.

Vorteile des Erfindungsgegenstandes liegen insbesondere in einer Gewichtsersparnis SUr das Steuerkabel sowie einer sehr guten Flexibilität des Schlauches.Advantages of the subject matter of the invention are in particular a weight saving SUr the control cable as well as a very good flexibility of the hose.

Die Erfindung ist nicht auf die dargestellte Ausführungsform beschränkt.The invention is not limited to the embodiment shown.

Einzelheiten können den Jeweiligen Erfordernissen angepaßt werden, ohne von Grundgedanken der Erfindung abzuweichen.Details can be adapted to the respective requirements, without departing from the basic concept of the invention.
