Durch die US 29 37 905 ist bereits ein Speichenrad mit einer Hohlkammerfelge bekannt. Die Innenwand dieser Hohlkammer bildet das Felgenbett, an dem an beiden Seiten nach außen gerichtet die sogenannten Felgenhörner zur Abstützung des Reifens mit dem Schlauch angeformt sind. Radial sind in gleichmäßigen Abständen durch die Außen wand der Hohlkammer in speziell nach außen gekröpften Bereichen entsprechend der Zahl der einzusetzenden Speichen langlochartige Bohrungen vorgesehen. Durch diese Bohrungen hindurch werden Kopfnippel eingesetzt, in denen die Speichen einschraubbar sind. Die Köpfe dieser Kopf nippel stützen sich innen an der Außenwand der Hohlkammer ab und ragen mit ihrem Schaft durch die Bohrungen nach außen. Die Verspannung der Speichen erfolgt von der Außenseite des Nippels her in bekannter Weise, wodurch die Speiche angezogen wird. Eine solche Montagetechnik erfordert die Ausbildung von relativ komplizierten Bohrungen bzw. Durchbrüchen in der Außenwand der Hohl kammerfelge mit entsprechender Ausprägung. Schwierig keiten bereitet auch das vollständige Verschließen der Bohrung nach Einsetzen der Kopfnippel.Through the US 29 37 905 a spoke wheel is already with a double wall rim known. The inner wall of this The rim well forms a hollow chamber on both sides the so-called rim flanges directed outwards Support the tire are molded with the tube. Radial are evenly spaced through the outside wall of the hollow chamber in specially cranked outwards Areas according to the number of used Spokes provided with oblong holes. Through this Head nipples are inserted through holes the spokes can be screwed in. The heads of this head nipples are supported on the inside of the outer wall of the hollow chamber and protrude with their shaft through the holes Outside. The spokes are braced by the Outside of the nipple forth in a known manner, whereby the spoke is tightened. Such an assembly technique requires the training of relatively complicated Bores or breakthroughs in the outer wall of the hollow Chamber rim with a corresponding design.

Die Aufgabe der Erfindung besteht darin, ein Speichenrad der eingangs genannten Art bezüglich der Montage der Speichen mit ihrem Kopfnippel zu vereinfachen und zu verbessern. The object of the invention is a spoke wheel of the type mentioned above with regard to the assembly of the Simplify and use spokes with their head nipples improve.
Gelöst wird die Erfindungsaufgabe mit einem Speichenrad mit sämtlichen Merkmalen des Anspruches 1. Ein solches erfindungs gemäßes Speichenrad benötigt nicht mehr die Bohrungen in der Innenwand der Hohlkammer. Das Felgenbett bleibt daher glatt, so daß ein Felgenband nicht mehr erforderlich ist. Da das Felgenbett auf diese Weise geschlossen bleibt bis auf die abge dichtete Ventileinführung, eignet sich eine solche Felge auch bei entsprechender Ausbildung der Felgenhörner für die Aufnahme von schlauchlosen Reifen. Die Montage der Speichen ist verein facht. Die erfindungsgemäßen Kopfnippel werden durch die ent sprechenden Bohrungen in der Außenwand der Hohlkammer der Felge eingesprengt. Nach Aufschrauben auf die jeweilige Speiche kann sofort das Anziehen der Speiche zur Spannung erfolgen. Es entfällt daher wie bei den bekannten Speichenrädern zunächst das Aufdrehen der Kopfnippel von der Seite des Felgenbettes her.The invention task is solved with a spoke wheel all features of claim 1. Such a fiction appropriate spoke wheel no longer needs the holes in the Inner wall of the hollow chamber. The rim base therefore remains smooth, so that a rim tape is no longer required. Since that Rim bed closed in this way remains except for the abge sealed valve entry, such a rim is also suitable with appropriate training of the rim flanges for the recording tubeless tires. The assembly of the spokes is united fold. The head nipples according to the invention are ent speaking holes in the outer wall of the hollow chamber Rim blown in. After screwing onto the respective spoke the spoke can be tightened to tension immediately. It therefore, as with the known spoke wheels, is initially eliminated unscrewing the head nipples from the side of the rim well forth.
Gemäß Anspruch 2 wird vorgeschlagen, die Kopfabschnitte durch zwei zueinander senkrechte Schlitze in der Art eines Kreuz schlitzes zu bilden. Dabei entstehen vier Kopfabschnitte, die aufgrund des verwendeten Metalles federnd sind und sich zur Montage nach innen eindrücken lassen. Nach Durchführung des Kopfes durch die entsprechende Bohrung in der Außenwand der Hohlkammer federn diese Kopfabschnitte wieder nach außen und verrasten innen hinter dem Bohrungsrand an der Außenwand der Hohlkammer.According to claim 2 it is proposed that the head sections two perpendicular slits in the manner of a cross to form slit. This creates four head sections that are resilient due to the metal used and become Allow assembly to be pushed in. After performing the Head through the corresponding hole in the outer wall of the These head sections spring outward and hollow again lock inside behind the edge of the hole on the outer wall of the Hollow chamber.
Erleichtert wird die Einführung des Kopfnippels durch Ein führungsschrägen am Ende des Kopfes bzw. der Kopfabschnitte.The insertion of the head nipple is facilitated by on bevels at the end of the head or head sections.
Durch die schräge Ausbildung der inneren Flanke des Kopfes wird bei entsprechender Ausbildung die Sicherheit der Verrastung des Kopfes hinter der Bohrung erreicht, ohne daß die Gefahr besteht, daß sich der Kopfnippel aus der Bohrung herauszieht.Due to the oblique formation of the inner flank of the head with appropriate training, the safety of the locking of the head behind the hole is reached without the danger there is that the head nipple pulls out of the hole.
