Description

  

  Aufblasbarer Ball aus Gummi oder Kunststoff    Die Erfindung betrifft einen aufblasbaren Ball  aus Gummi oder Kunststoff, mit einem     Rückschlag-          ventil    für die einzublasende Luft.  



  Der erfindungsgemässe Ball zeichnet sich aus  durch einen angepressten, dünnwandigen, gelochten  Sack, der in das Ballinnere hineinragt und das Ventil  zur Verhinderung des     Entweichens    der in den Ball  hineingeblasenen Luft aufweist.  



  Die Zeichnung veranschaulicht drei Ausführungs  beispiele der Erfindung und zwar stellt       Fig.   <B>1</B> das Ventil mit Kugel,       Fig.    2 das Ventil mit Zwischenwand und       Fig.   <B>3</B> ein Ventil mit Gehäuse und federbelasteter  Kugel dar.  



  An die     unsteife    Ballwand<B>1</B> aus Kunststoff oder  Gummi ist der als Ventil dienende oder dieses auf  nehmende dünnwandige Sack 2 angepresst, der an  seinem in das Ballinnere hineinragenden Ende     Luft-          durchtrittslöcher   <B>3</B> aufweist. Durch die zentrale     öff-          nung    wird eine Kugel<B>5</B> von aussen her eingeschoben.  Zum Aufblasen des Balles wird eine Luftpumpe in  die     öffnung   <B>7</B> der Wandung eingesetzt. Beim Ein  pumpen dehnt sich der Luftsack im Bereich der Ku  gel<B>5,</B> so dass sie durch die Löcher<B>3</B> in den Ball ein  treten kann.

   Den Rückweg verhindert die Kugel<B>5,</B> da  der Luftdruck im Ballinnern nicht     ausreich    t, den  Luftsack zu dehnen.  



  Eine in den Sack eingesetzte Zwischenwand<B>6</B>  nach     Fig.    2 verhindert ein Entweichen der in das  Ballinnere geblasenen Luft dadurch, dass der Innen  druck den Sack zusammenpresst (siehe     Fig.    2 gestri  chelte Linien) und so die Löcher verdeckt.  



  Der Sack 2 ist dabei in seinem gelochten Teil so  dünn ausgebildet, dass der Innendruck des Balles ge  nügt, um zu bewirken, dass die sich gegenüberliegen  den Wände zusammengedrückt werden. Unter Um-    ständen und bei zueinander versetzten Löchern kann  auf die Zwischenwand<B>6</B> auch verzichtet werden.  



  In     Fig.   <B>3</B> ist in den Sack 2 ein Ventilgehäuse<B>8</B>  von aussen her eingesetzt, dessen obere     öffnung   <B>11</B>  durch die Kugel<B>5,</B> die unter Einwirkung einer Feder  <B>9</B> steht, abgesperrt ist. Die Löcher<B>3</B> im Luftsack  korrespondieren mit den     öffnungen    12 im Ventil  gehäuse, die in den Raum des Ventilgehäuses ein  münden, welcher näher beim Ballzentrum ]legt, als  die Kugel<B>5.</B> Die Stirnwand des Gehäuses dient als  Kugelsitz<B>10</B> und ist an dieser Stelle entsprechend ab  gerundet.  



  Dieses Sperrmittel hat den Vorteil, dass durch  Einführen eines Drahtes die Absperrkugel von ihrem  Sitz abgehoben werden kann, so dass die Luft aus  dem Ballinneren entweicht. Der Ball steht also nur  unter Druck, solange er gebraucht wird. Bei Nicht  gebrauch wird er entleert und dadurch geschont.



  Inflatable Ball Made of Rubber or Plastic The invention relates to an inflatable ball made of rubber or plastic, with a non-return valve for the air to be injected.



  The ball according to the invention is characterized by a pressed, thin-walled, perforated sack which protrudes into the interior of the ball and has the valve to prevent the air blown into the ball from escaping.



  The drawing illustrates three exemplary embodiments of the invention, namely FIG. 1 shows the valve with a ball, FIG. 2 shows the valve with a partition and FIG. 3 shows a valve with a housing and spring-loaded Sphere.



  The thin-walled sack 2 serving as a valve or receiving it is pressed onto the unstiff ball wall <B> 1 </B> made of plastic or rubber and has air passage holes <B> 3 </B> at its end protruding into the interior of the ball . A ball <B> 5 </B> is inserted from the outside through the central opening. To inflate the ball, an air pump is inserted into the opening 7 in the wall. When pumping in, the airbag expands in the area of the ball <B> 5 </B> so that it can enter the ball through the holes <B> 3 </B>.

   The ball <B> 5 </B> prevents the return path because the air pressure inside the ball is not sufficient to stretch the airbag.



  A partition <B> 6 </B> according to FIG. 2 inserted into the sack prevents the air blown into the inside of the ball from escaping by the fact that the internal pressure compresses the sack (see dashed lines in FIG. 2) and thus covers the holes .



  The bag 2 is so thin in its perforated part that the internal pressure of the ball is sufficient to cause the opposing walls to be compressed. The partition <B> 6 </B> can also be dispensed with under certain circumstances and when the holes are offset from one another.



  In FIG. 3, a valve housing 8 is inserted from the outside into the sack 2, the upper opening 11 of which is penetrated by the ball 5, </B> which is under the action of a spring <B> 9 </B> is locked. The holes <B> 3 </B> in the airbag correspond to the openings 12 in the valve housing, which open into the space of the valve housing, which is closer to the center of the ball than the ball <B> 5. </B> Die The end wall of the housing serves as a ball seat <B> 10 </B> and is rounded off accordingly at this point.



  This locking means has the advantage that the locking ball can be lifted from its seat by inserting a wire, so that the air escapes from the inside of the ball. The ball is only under pressure while it is needed. When not in use, it is emptied and thus spared.
