Doppelwandiger Saugschlauch. Patentiert im Deutschen Reiche vom 27. Mai 1913 ab.Double-walled suction hose. Patented in the German Empire on May 27, 1913.
Die Erfindung betrifft einen doppelwandigen Saugschlauch mit einem Luftraum zwischen den Wandungen.The invention relates to a double-walled suction hose with an air space between the walls.
Doppelwandige Schläuche mit einem. Luftraum-, zwischen den Wandungen waren bisher nur als Druckschläuche bekannt und gebräuchlich. Diese Schläuche konnten, weil ihr Luftraum mit dem Schlauchinnern durch öffnunr gen in Verbindung stand und daher gegenDouble-walled tubing with a. Airspace-, between the walls were previously only known and used as pressure hoses. These hoses could because their air space with the hose interior through openings in connection and therefore against
ίο äußeren Druck nicht abgestützt waren, als Saugschläuche nicht verwendet werden. Als solche wurden vielmehr bisher Schläuche benutzt, die meist aus mehreren übereinanderliegenden Stofflagen hergestellt und durch innere und äußere Drahteinfassungen bewehrt waren. Bei diesen letztgenannten Schläuchen ist naturgemäß die Beweglichkeit herabgemindert ; auch ihre Herstellung ist verhältnismäßig teuer und eine Reparatur schwierig auszufüh-ίο external pressures were unsupported when Suction hoses are not used. Rather, hoses have hitherto been used as such, which are usually made of several layers of fabric on top of each other and reinforced with inner and outer wire edging was. In the case of these last-mentioned hoses, the mobility is naturally reduced ; They are also relatively expensive to manufacture and difficult to repair.
Durch den Erfindungsgegenstand wird nun ein doppelwandiger, unbewehrter. Schlauch als Saugschlauch geschaffen, der die Nachteile eines aus mehreren Stofflagen bestehenden und durch Drahtumwicklungen bewehrten Schlauches nicht aufweist. Die Erfindung besteht darin, daß der Luftraum zwischen den Schlauchwandungen gegen das Schlauchinnere abgeschlossen, durch Zwischenwände versteift und von außen aufpumpbar ist.The subject of the invention now becomes a double-walled, unreinforced one. Hose as Created suction hose, which has the disadvantages of a consisting of several layers of fabric and does not have hose reinforced with wire wraps. The invention exists in that the air space between the hose walls is closed off from the inside of the hose, is stiffened by partitions and can be inflated from the outside.
Eine Ausführungsform des Erfindungsgegenstandes ist in der Zeichnung dargestellt, und zwar zeigen:An embodiment of the subject matter of the invention is shown in the drawing, and although show:
Fig. ι einen Längsschnitt durch den Schlauch, undFig. Ι a longitudinal section through the hose, and
Fig. 2 einen Querschnitt nach Linie A-B der Fig. i.FIG. 2 shows a cross section along line AB of FIG.
Der Schlauch besteht aus der äußeren Schlauchwand a, der inneren Schlauchwand b und den zwischen diesen radial stehenden Längswänden c. Die Wandungen α und b vereinigen sich an beiden Enden und tragen an einem Ende den Saugkorb, am anderen Ende die Kupplungsmittel zum Anbringen an der Pumpe. Die zwischen den Wänden α und b die Kammern d abteilenden Versteifungswände c sind mit Öffnungen f versehen, so daß die Kammern miteinander in Verbindung stehen. Mit Hilfe einer an den Ventilkörper e anschließbaren Luftpumpe können die Kammern aufgepumpt werden.The hose consists of the outer hose wall a, the inner hose wall b and the longitudinal walls c extending radially between these. The walls α and b unite at both ends and carry the suction strainer at one end and the coupling means for attachment to the pump at the other end. The stiffening walls c dividing the chambers d between the walls α and b are provided with openings f so that the chambers are in communication with one another. The chambers can be inflated with the aid of an air pump that can be connected to the valve body e.
Der Saugschlauch wird zunächst in unaufgepumptem Zustand in die verlangte Lage gebracht, wobei er sich infolge seiner leichten Beweglichkeit und Schmiegsamkeit allen Geländeverhältnissen leicht anpaßt, so daß er sich insbesondere für die Anwendung an schwer zugänglichen Orten eignet. Ist der Schlauch angeschlossen und in die richtige Lage gebracht, so werden die Kammern d mit Druckluft oder sonst einem hochgespannten Gase ausgefüllt. Nach dem Aufpumpen widersteht der Schlauch als Saugschlauch in sicherer Weise dem Atmosphärendruck. Nach beendeter Verwendung wird das Druckgas wieder ausgelassen, und der Schlauch kann infolge seiner Schmiegsamkeit leicht weggenommen und transportiert werden. Die Stege c zwischen den Kammern können beliebig, z. B. spiralförmig, geführt werden.The suction hose is first brought into the required position in the uninflated state, whereby it adapts easily to all terrain conditions due to its easy mobility and flexibility, so that it is particularly suitable for use in places that are difficult to access. If the hose is connected and brought into the correct position, the chambers d are filled with compressed air or some other high-tension gas. After inflation, the hose, acting as a suction hose, withstands atmospheric pressure in a safe way. After the end of use, the pressurized gas is released again, and the hose can be easily removed and transported due to its flexibility. The webs c between the chambers can be arbitrary, for. B. spirally guided.
