 graphische Dunkelkammern verwendet wird ; er ist mit seinen Enden an den beiden Elementen des Kugelgelenkes befestigt. Durch den Balg wird auch die Dichtigkeit der Verbindung erhöht. 



   Die Innendurchmesser der beiden Elemente al und bl sind deiart bemessen, dass die Schallwellen bei den vorkommenden Winkeleinstellungen der Rohrelement nicht gegen eine Kante stossen, damit der Ton keine Beeinträchtigung erfährt. 



   PATENT-ANSPRÜCHE :
1. Kugelgelenkverbindung für Rohre, insbesondere Tonarme von Phonographen, dadurch gekennzeichnet, dass die Rohrenden durch ein Band oder einen Faden   delart   verbunden sind, dass eines der Fadenenden in den Mittelpunkt des Kugelgelenkes zu liegen kommt. 



   2. Gelenkverbindung   nach Anspiueh l, dadurch gekennzeichnet,   dass das Element (al) des Kugelgelenkes mit einem Teile   (a2)   ausgestattet ist, der im Mittelpunkte des Kugelgelenkes mit einem Loch   (a3)   versehen ist, durch welches der Faden (e) durchgezogen werden kann, der sich mit seinem verdickten Ende gegen den Teil   (a2)   abstützt. 



     3. Gelenkverbindung nach Anspiueh   2,   dadurch gekennzeichnet, dass   der mit einem Loch zur
Aufnahme des Fadens ausgestattete Teil   (a2)   als Stift ausgebildet ist.

 graphic darkrooms are used; it is attached with its ends to the two elements of the ball joint. The bellows also increase the tightness of the connection.



   The inner diameter of the two elements a1 and b1 are dimensioned in such a way that the sound waves do not hit an edge when the angle settings of the pipe element occur, so that the sound is not impaired.



   PATENT CLAIMS:
1. Ball joint connection for tubes, in particular tonearms of phonographs, characterized in that the tube ends are delart connected by a tape or thread that one of the thread ends comes to rest in the center of the ball joint.



   2. Articulated connection according to Anspiueh l, characterized in that the element (a1) of the ball joint is equipped with a part (a2) which is provided in the center of the ball joint with a hole (a3) through which the thread (e) is pulled can, which is supported with its thickened end against the part (a2).



     3. Articulated connection according to Anspiueh 2, characterized in that the with a hole for
Receiving the thread equipped part (a2) is designed as a pin.

Claims

4. Articulated connection according to claim l, characterized in that the element (b1) is provided with a Que bohmng (b3) which is intended to receive the free thread end.

5. Articulated connection according to claim 4, characterized in that the free end of the tension member (e) is designed as a screw spindle onto which a nut (cl) can be screwed.

6. Articulated connection according to claim 5, characterized in that the nut (cl) by a Washer is sealed.

7. Articulated connection according to claim 5, characterized in that the loosening of the thread or tape by a screw fe od. Like. Is prevented.

8. Articulated connection according to claim 7, characterized in that a spring (tell) is switched on in the pulling element (e), by means of which it is placed in such tension that it ensures the immobility of the tonearm necessary for the vibration transmission, the effectiveness of the ball joint but not handicapped.

9. Articulated connection according to claim 1, characterized in that means are provided to prevent the rotation of the tubes about their longitudinal axis.

10. Articulated connection according to claim 9, characterized in that the rotation of the tubular elements about their longitudinal axes is prevented by a bellows (d). EMI2.1
