Description

Aufblasbarer Gummihohlkörper Die Erfindung betrifft einen Gummihohlkörper, der aufgeblasen oder mit irgendeiner Flüssigkeit gefüllt werden kann, und außerdem ein Herstellungsverfahren für den Hohlkörper.Inflatable hollow rubber body The invention relates to a hollow rubber body, which can be inflated or filled with any liquid, and moreover a manufacturing process for the hollow body.

Zweck der Erfindung ist, eine Anordnung zu schaffen, bei der die Hohlräume an einer Stelle des Hohlkörpers nicht ausgebeult werden, wenn eine andere Stelle unter Druck gesetzt wird, und bei der ferner örtliche Anschwellungen beim Aufblasen verhindert werden. Es wird dies im wesentlichen durch eine Verbindung der beiden Hauptwände des Gummikörpers mit Hilfe einer an einzelnen Stellen der Hauptwände befestigten Zwischenwand aus biegsamem Stoff erreicht.The purpose of the invention is to create an arrangement in which the cavities do not bulge at one point of the hollow body if another point is pressurized, and also localized swelling when inflated be prevented. It does so essentially by combining the two Main walls of the rubber body with the help of one at individual points of the main walls Attached partition made of flexible fabric achieved.

Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt; es sind Abb. i eine Aufsicht, teilweise geschnitten; Abb. a ein Schnitt durch den Gummikörper; Abb. 3 eine Aufsicht einer Platte, die bei der Herstellung des Körpers benutzt wird; Abb. q: ein Querschnitt durch eine Form, auf welche der Körper gerollt ist.In the drawing, the invention is shown in one embodiment; Fig. i is a top view, partially in section; Fig. A a section through the Rubber body; Fig. 3 is a plan view of a plate used in the manufacture of the body is used; Fig. Q: a cross-section through a shape on which the body is rolled is.

Die für die Darstellung gewählte Ausführungsform des Körpers ist ein Gummiluftkissen, doch soll auf diese die Erfindung nicht beschränkt sein.The embodiment of the body chosen for the illustration is a Rubber air cushions, but the invention is not intended to be limited thereto.

Das Kissen kann eine beliebige Form erhalten. Die hier gezeigte ist viereckig und besteht aus zwei Außenwänden A und B, die aus Gummitücken gebildet werden. Die Außenwände sind längs ihrer Kanten so miteinander verbunden, daß der Körper eine geschlossene Hülle oder einen Beutel bildet. Die beiden Gummistücke können durch Gummiklebstoff wie er bei der Herstellung von Gummiwaren benutzt wird, aneinander befestigt werden. Vorzugsweise sind die Seitenkanten durch Vulkanisieren verbunden.The pillow can have any shape. The one shown here is quadrangular and consists of two outer walls A and B, which are formed from pieces of rubber will. The outer walls are connected along their edges so that the Body forms a closed envelope or bag. The two pieces of rubber can be achieved by rubber adhesive as it is used in the manufacture of rubber goods, be attached to each other. Preferably the side edges are vulcanized tied together.

Zwischen den Stücken A und B befindet sich eine biegsame Zwischenwand C, vorzugsweise aus Gummi. Die Zwischenwand C ist an den Innenflächen der Wände A und B an mehreren kleinen Flächenstücken befestigt. Vorzugsweise sind die Befestigungsstellen zwischen C und A, gegenüber denjenigen zwischen C und B versetzt. Die Enden der Zwischenwand C sind vorzugsweise weder an A noch an B befestigt, so daß die Luft frei um die Kanten streichen kann.Between the pieces A and B there is a flexible partition C, preferably made of rubber. The intermediate wall C is attached to the inner surfaces of the walls A and B at several small pieces of surface. The fastening points between C and A are preferably offset from those between C and B. The ends of the partition C are preferably not attached to either A or B so that the air can freely sweep around the edges.

Auf diese Weise werden eine Anzahl von Luftsäcken oder Taschen zu beiden Seiten des Zwischengliedes C gebildet. Eine jede Tasche ist mit den Nachbartaschen verbunden, so daß die Luft von einer zur anderen Tasche fließen kann, doch ist der Luftweg andrerseits beschränkt, so daß eine Stelle der Hülle unter Druck kommen kann, ohne daß eine andre Stelle ausgebeult wird.In this way, a number of air sacs or bags become too both sides of the intermediate member C formed. Each pocket is with the neighboring pockets connected so that air can flow from one pocket to the other, but it is On the other hand, airway is restricted, so that one point of the envelope comes under pressure can without bulging elsewhere.

Außerdem wirkt die Zwischenwand C als eine biegsame Verbindung zwischen den äußeren Wänden A und B, durch die diese an zu starkem Ausbeulen beim Aufblasen verhindert werden.In addition, the partition C acts as a flexible connection between the outer walls A and B, which prevent them from bulging too much when inflated be prevented.

Zum Aufblasen ist der Gegenstand mit einem Ventil G bekannter Art versehen (Abb. f). Das Kissen kann statt mit Luft auch mit Wasser oder andrer Flüssigkeit gefüllt werden. Das Kissen wird vorzugsweise folgendermassen hergestellt: Man nimmt zwei Stücke Rohgummi von entsprechender Größe und ein Zwischenstück, gleichfalls aus Rohgummi, ferner ein Blatt Papier D (Abb. 3) o. dgl. von der lichten Größe der Hülle. Die Hülle ist etwas größer als das Zwischenstück c. Das Blatt Papier ist mit einer Anzahl Öffnungen E von beliebiger Anordnung versehen.For inflation, the object with a valve G is of known type provided (Fig. f). The pillow can be filled with water or other liquid instead of air be filled. The pillow is preferably made as follows: You take two pieces of raw rubber of the appropriate size and an intermediate piece, likewise made of raw rubber, also a sheet of paper D (Fig. 3) or the like. The clear size of the Covering. The envelope is slightly larger than the intermediate piece c. The sheet of paper is provided with a number of openings E of any arrangement.

Das Blatt D wird auf eines der Gummistücke gelegt, das als die eine Außenwand dienen soll. Dann legt man das Zwischenstück C auf das Blatt D, ein zweites Blatt Papier D o. dgl., das dem ersten Blatt D ähnelt, auf das Zwischenstück C und endlich das andre Außenstück auf das zweite Papierblatt D.Sheet D is placed on top of one of the pieces of rubber that will serve as the one outer wall. Then place the intermediate piece C on the sheet D, a second sheet of paper D or the like, which is similar to the first sheet D , on the intermediate piece C and finally the other outer piece on the second paper sheet D.

Die beiden äußeren Gummistücke sind nun an ihren Kanten in Berührung miteinander, ferner stehen diese Außenstücke an denjenigen Stellen, wo sich Löcher in den Papierblättern befinden, mit dem Zwischenstück in Berührung. Jetzt wird das Ganze vulkanisiert, und es entstehen Verschmelzungen zwischen den äußeren Gummistücken an ihren Kanten, ebenso an denjenigen Stellen, wo sich Löcher im Papier befinden, zwischen dem Mittelstück und den äußeren Gummistücken.The two outer pieces of rubber are now in contact at their edges with each other, furthermore, these outer pieces are in those places where there are holes are in the sheets of paper, in contact with the spacer. Now it will The whole thing vulcanizes, and there are fusions between the outer pieces of rubber at their edges, as well as in those places where there are holes in the paper, between the middle piece and the outer rubber pieces.

Vorzugsweise wird der Gegenstand auf einem Zylinder F (Abb. 4) vulkanisiert; auf diese Weise erhält der fertige Gegenstand die Neigung, sich leicht zu krümmen, so daß eine Stapelung und Beförderung der Gummikörper erleichtert wird.Preferably the object is vulcanized on a cylinder F (Fig. 4); in this way the finished object tends to bend slightly, so that stacking and conveying of the rubber bodies is facilitated.
