Description

Aufblasbarer Spielball mit hohlem Propfenansatz an der Ballinnenseite Die Erfindung bezieht sich auf aufblasbare Spielbälle, z. B. Blasen für Fußbälle, bei denen die Ballwand an ihrer Innenseite einen hohlen Pfropfen besitzt, in den zum Zwecke des Aufblasens von außen her eine Kanülennadel eingeführt wird. Das Entweichen der Luft wird bei solchen bekannten Bällen durch ein das Pfropfenende abschließendes Rückschlagventil verhütet. Solche Ventile lassen sich sehr schwer dicht halten, und es besteht die Gefahr, daß sie durch heftige Stöße oder Schläge, denen der Ball dauernd ausgesetzt ist, beschädigt oder aus ihrer Abdichtlage entfernt werden. Nach der Erfindung wird dieser Übelstand dadurch beseitigt, daß der Pfropfenhohlraum mit einem die Einstichstelle der Kanüle selbsttätig abdichtenden Füllstoffe angefüllt wird. Dadurch wird zugleich auch die Herstellung der Bälle vereinfacht und verbilligt.Inflatable play ball with a hollow plug attachment on the inside of the ball The invention relates to inflatable play balls, e.g. B. Bubbles for soccer balls, in which the ball wall has a hollow plug on its inside, into the a cannula needle is inserted for the purpose of inflation from the outside. The escape The air is in such known balls through a plug end closing Check valve prevented. Such valves are very difficult to keep tight, and there is a risk of being hit by violent knocks or blows from the ball is permanently exposed, damaged or removed from its sealing layer. To the invention, this drawback is eliminated in that the plug cavity filled with a filler that automatically seals the puncture site of the cannula will. This also simplifies and makes the production of the balls cheaper.

Der Füllstoff, z. B. ein Gemisch von uriporösen Körnern und Gummi nicht angreifender Lösung, wird durch ein über das freie Pfropfenende gezogenes Blättchen o. dgl. aus Gummi, Leder oder Gewebe am Herausfallen aus dem Pfropfennapf gehindert. Gemisch und Blättchen werden von der in den Pfropfen eingestochenen Kanülennadel durchfahren, die beim Zurückziehen von der klebrigen Masse ein Körnchen vor oder in den Einstichkanal der Blase zieht und ihn dadurch luftdicht abschließt. Insofern verdient ein klebriges, nicht erhärtendes Gemisch, für das sich geschmolzenes Gummi mit Gummikörnern o. dgl. als zweckmäßig erwiesen hat, den Vorzug vor einer trockenen Körnermasse.The filler, e.g. B. a mixture of uriporous grains and gum non-attacking solution, is pulled through the free end of the plug Leaflets or the like made of rubber, leather or fabric fall out of the stopper prevented. The mixture and the leaflet are removed from the needle inserted into the stopper drive through which, when pulling back from the sticky mass, a grain in front of or pulls into the puncture channel of the bladder and thereby seals it airtight. To that extent deserves a sticky, non-hardening mixture that melted rubber does with rubber grains or the like. Has proven to be useful, the preference over a dry one Grain mass.
