Description
Auswechselbares Fadentraggestell für gasgefüllte elektrische Glühlampen. Die Erfindung betrifft ein auswechselbares Fadentraggestell für elektrische Metallfadenlampen. Es ist bekannt, diese Fadentraggestelle so auszubilden, daß die Fadenstützen zwecks Einführung des bewickelten Gestelles durch ein enges Loch der Birnenspitze schirmartig zusammengebogen und nach dem Einführen wieder gespreizt werden können.Exchangeable thread support frame for gas-filled electric light bulbs. The invention relates to an exchangeable thread support frame for electric metal thread lamps. It is known to design these thread support frames so that the thread supports for the purpose Introduction of the wrapped frame through a narrow hole in the pear tip like an umbrella can be bent together and spread again after insertion.
Die vorliegende Erfindung behandelt ein solches Fadentraggestell für sogenannte Halbwattlampen, welches ebenfalls durch eine verhältnismäßig enge Öffnung an der Spitze der Glühbirne eingebracht bzw. ausgewech@;elt werden soll. Bekanntlich werden an den Fadenstützen Einschmelzstellen durch die beim Einschmelzen auf sie einwirkende Hitze leicht spröde und brüchig. Erfindungsgemäß wird deshalb der interne, in die Glaslinse des Fadentraggestelles eingeschmolzene stärkere Draht jedes in an und für sich bekannter Weise aus zwei Drähten verschiedener Stärke zusammengesetzten Fadenträgers, kurz vor seiner Einschmelzstelle, schleifenartig gewunden, und um zu vermeiden, daß beim Hin-und Herbiegen dieser Drähte ein Abbrechen an ihrer Einschmelzstelle eintritt, um einen Ring aus Isolationsmasse herumgeschlungen. Dieser isolierende Ring soll außerdem verhüten, daß eine gegenseitige Berührung der Drähte untereinander stattfindet. Innerhalb des isolierenden Ringes ist eine zylindrische Verlängerung der Mitteltragstütze angeordnet, welche eine seitliche Verschiebung des Ringes und somit ein Verbiegen der Drähte an der Einschmelzstelle verhindert.The present invention deals with such a suture support frame for so-called half-watt lamps, which also pass through a relatively narrow opening to be inserted or replaced at the tip of the light bulb. As is well known are melt-in points on the thread supports due to the melting on them exposed heat slightly brittle and fragile. According to the invention, the internal, thicker wire melted into the glass lens of the thread support frame each in in a manner known per se composed of two wires of different strengths Thread carrier, just before its melting point, wound like a loop, and around to avoid that when these wires are bent back and forth, they break off at their melting point enters, wrapped around a ring of insulating compound. This isolating one The ring should also prevent the wires from touching one another takes place. Inside the insulating ring is a cylindrical extension the central support is arranged, which allows a lateral displacement of the ring and thus preventing the wires from bending at the melting point.
In der Zeichnung ist das neue Fadentraggestell in der Ansicht dargestellt, und zwar einmal auf der an der Mitteltragstütze befindlichen Linse festgeklemmt, das andere Mal zusammengebogen im Augenblick seiner Einbringung bzw. Auswechslung. Das Traggestell besteht aus dem Klauenstück a, dem Glasstab b, den Fadenträgern c mit den bekannten schweineschwänzchenförmigen Tragäsend und dem Glasringe e.In the drawing, the new thread support frame is shown in the view, namely once clamped on the lens located on the central support support, the other time bent together at the moment of its introduction or replacement. The support frame consists of the claw piece a, the glass rod b, the thread carriers c with the well-known pig-tail-shaped support and the glass rings e.
