Description
Die Erfindung betrifft eine Anordnung zum Schützen von Luftkammern gegen ein Durchstoßen und zum gleichzeitigen sicheren Verschließen der entstandenen Öffnungen.The invention relates to an arrangement for protecting air chambers against puncturing and at the same time secure closing of the resulting openings.
Bisher stellte man Anordnungen zum Schützen von Luftkammern, wie beispielsweise Reifen oder Bällen, dadurch her, daß man entweder eine widerstandsfähige Einlage in die Umhüllung einarbeitete bzw. mit ihr verband, oder aber eine Flüssigkeit in die Kammer selbst einbrachte. In beiden Fällen erhöhte sich entweder das Gewicht der entsprechenden Gegenstände, oder es schwächte sich ihre Struktur, wodurch sich eine Zwangslage und ein Ungleichgewicht hinsichtlich der Raumausnutzung ergab. Oft wurden die Gegenstände sogar unverwendbar.So far, arrangements for protecting air chambers, such as tires or balls, have been produced by that one either worked a resistant insert into the envelope or connected it to it, or one Liquid introduced into the chamber itself. In both cases, either the weight of the corresponding increased Objects, or it weakened their structure, creating a predicament and imbalance in terms of things the use of space resulted. Often the objects even became unusable.

Die Anordnung nach der Erfindung vermeidet diese Nachteile und gestattet demnach einer weichen, plastischen Substanz, sämtliche Gestalten anzunehmen. Bei vermindertem Raumbedarf wird die Widerstandsfähigkeit erhöht, und zwar auch durch den Druck, der von der Luftkammer gegen die Umhüllung ausgeübt wird. Die widerstandsfähige und weiche Schutzhaut bringt außerdem den Vorteil mit sich, daß sie sich an sämtliche Materialien der Kammern und der Umhüllungen anpaßt und im Falle einer Durchstoßung die entstandenen Öffnungen sogar verschließt, und zwar unter der Wirkung des Drucks, der auf sie einwirkt und sie dazu bringt, zwischen die Ränder der eingerissenen Stelle einzufließen.The arrangement according to the invention avoids these disadvantages and therefore allows a soft, plastic Substance to take on all shapes. With less space required, the resistance is increased, also by the pressure exerted against the envelope by the air chamber. The resilient and soft protective skin also has the advantage that it adapts to all materials of the chambers and adapts to the sheaths and, in the event of a puncture, even closes the openings created, namely under the action of the pressure that acts on them, causing them to move between the edges of the torn Place.
Die Anordnung nach der Erfindung kennzeichnet sich durch die Verwendung von Pasern aus Baumwolle, nämlich sogenannter hydrophiler Baumwolle, welche mit einer Flüssigkeit wie etwa Wasser derart getränkt ist, daß die sehr langen, sehr weichen Fasern zwar einerseits ihre extreme Feinheit beibehalten, sich andererseits jedoch unter der Wirkung des Drucks zusammenballen. Die fasrige Schutzhaut sitzt in einer hermetisch und undurchlässig abgedichteten Einlage, welche zwischen der Kammer und der Umhüllung derart angeordnet ist, daß sie sich aufgrund ihrer Verformbarkeit, ihrer Leichtigkeit und ihrer geringen Stärke an sämtliche Formen anpassen kann, wie beispielsweise die von Bällen, Reifen od.dgl.The arrangement according to the invention is characterized by the use of fibers made of cotton, namely So-called hydrophilic cotton, which is soaked with a liquid such as water in such a way that the very long, very soft fibers retain their extreme fineness on the one hand, but on the other hand maintain their extreme fineness clump together under the action of pressure. The fibrous protective skin sits in a hermetic and impermeable manner sealed liner, which is arranged between the chamber and the envelope in such a way that they are due to their deformability, their lightness and their low strength can adapt to all shapes, such as those of balls, tires or the like.

Die selbstdichtende Schutzeinlage umfaßt ein Gewebe aus Baumwollfasern, und zwar aus sogenannter hydrophiler Baumwolle, welche mit Wasser getränkt ist. Dieses Baumwollgewebe wird von Außenschichten 2 und J5 dicht und undurchlässig eingeschlossen, wobei die Schichten eine einstückige Umhüllung bilden.The self-sealing protective insert comprises a fabric made of cotton fibers, namely made of so-called hydrophilic cotton, which is soaked in water. This cotton fabric becomes dense and impermeable by outer layers 2 and J5 included, wherein the layers form a one-piece envelope.
Die Schichten 2 und j5 sind ihrer Formgebung nach an den jeweiligen Verwendungszweck angepaßt* wie es beispielsweise mit der Bezugsziffer 4 in Fig. 2 wiedergegeben ist. Sie sitzen dort zwischen einer Fußballblase 5 und einer Umhüllung 6.The layers 2 and j5 are shaped according to the adapted to the respective intended use * as shown, for example, with the reference number 4 in FIG. she sit there between a soccer ball 5 and a cover 6.
Eine entsprechende Einlage kann,, wie es die Bezugsziffer 7 in Fig. 5 angibt, auf der Außenhaut 8 eines Reifens und unterhalb der Lauffläche 9 angeordnet werdenοA corresponding deposit can, as indicated by the reference number 7 in Fig. 5 indicates to be arranged on the outer skin 8 of a tire and below the tread 9 o

Die Fasern aus reiner Baumwolle, die unter Druck gesetzt und mit Wasser getränkt sind, sehwellen an, sobald ein Fremdkörper eindringt.The pure cotton fibers that are pressurized and are soaked in water, the eyes wave as soon as a foreign body is caught penetrates.
Die Abschirmung ist umso stabiler und fester, je höher der Druck ist. Damit wird die Widerstandsfähigkeit der Struktur umso größer je tiefer die Ränder der Einrißsteile sind.The shielding is more stable and stronger the higher the pressure. This increases the resilience of the structure the larger the deeper the edges of the tear parts are.
Die von der Feuchtigkeit sehr geschmeidig gehaltene reine Zellulose wird strömungsfähig, ohne daß die Fasern ihre Zugfestigkeit und Torsionsfestigkeit verlieren.The pure cellulose, which is kept very supple by the moisture, becomes flowable without the fibers losing their tensile strength and lose torsional strength.
Das Baumwollgewebe kann mit reinem Wasser getränkt werden. Auch kann man eine wässrige, mehr oder weniger viskose Lösung verwenden, die gegen Verdunstung, schützt, wie beispielsweise eine fetthaltige Substanz. Die obigen Ausführungsbeispiele können hinsichtlich ihrer Formgebungen, Dimensionierungen und Anordnungen der verschiedenen Elemente sowie hinsichtlich der verwendeten Materialien abgewandelt werden, ohne daß vom Erfindungsgedanken abgewichen würde.The cotton fabric can be soaked with pure water. You can also use an aqueous, more or less viscous solution use that protects against evaporation, such as a fatty substance. The above embodiments can with regard to their shapes, dimensions and arrangements of the various elements as well as with regard to the materials used can be modified without deviating from the inventive concept.
