Description

Fadentraggcstell fier elektrische Glühlampen. Zwecks Wiederherstellung ausgebrannter elektrischer Glühlampen ist es bekannt, durch eine öffnung an der Birnenspitze ein zusanamenlegbaresFadentraggestell einzuführen, welches an der bereits vorher teilweise abgebrochenen Mittelstütze des alten Fadentraggestelles befestigt wird.Thread carrier for electric light bulbs. In order to restore Burned-out electric incandescent lamps are known to pass through an opening on the Pear tip to introduce a collapsible thread support frame, which is attached to the already previously partially broken central support of the old thread support frame attached will.

Vorliegende Erfindung hat ein ebenfalls auswechselbares Fadentraggestell zur Grundlage, welches sich von den bekannten aber dadurch a® unterscheidet, daß auf der Mittelstütze ein in achsialer Richtung drehbarer Fadenkranz aus schraubenförmig gewundenen Fadenteilen angeordnet ist, welcher-zwecks-Einführung in die bzw. Entfernung aus der Glühbirne um die Mittelstütze des Fadentraggestelles herumgewickelt werden kann. Hierdurch wird einerseits erreicht, daß das Loch an der Birnenspitze sehr eng gehalten werden kann, anderseits fallen die bei den bisher bekannten zur sammenleg oder -schiebbaren - Traggestellen notwendigen Mechanismen fort, welche, in der evakuierten Birne verbleibend, einen sehr schädlichen Einfluß auf die Lebensdauer der Lampe ausüben. Um eine etwaige Verlagerung des Leuchtdrahtes zu vermeiden, kann derselbe noch von der Mittelstütze des Fadentraggestelles aus abgesteift werden.The present invention also has an interchangeable thread support frame to the basis, which differs from the known but thereby a® differs, that on the central support a thread wreath rotatable in the axial direction from helical winding thread parts is arranged, which-for the purpose of introduction into or removal wrapped from the light bulb around the center support of the thread support frame can. This achieves on the one hand that the hole at the pear tip is very can be kept close, on the other hand, the previously known fall into the amble or -sliding - supporting frames necessary mechanisms, which, in the evacuated Bulb remaining, a very detrimental affect on lamp life exercise. In order to avoid a possible displacement of the light wire, the same can still be stiffened from the central support of the thread support frame.

Die Zeichnung veranschaulicht die beispielsweise Ausführungsform eines solchen Traggestelles.The drawing illustrates the example embodiment of a such a support frame.

Abb. i zeigt dasselbe in der Ansicht.Fig. I shows the same in view.

Die untere Linse a ist in bekannter Weise auf den Stumpf der alten Mittelstütze b gesteckt und dort festgeklemmt. Die neue Mittelstütze c trägt die obere Linse d, welche um eine Rille der Mittelstütze c drehbar ist. Die Glühfadenteile e sind mit ihren beiderseitigen Enden jeweils an den Linsen a und d festgeklemmt.The lower lens a is placed in a known manner on the stump of the old center support b and clamped there. The new center support c carries the upper lens d, which is rotatable about a groove in the center support c. The ends of the filament parts e are clamped to the lenses a and d, respectively.

Abb. a zeigt das, neue Fadentraggestell mit dem um die Mittelstütze geschlungenen Leuchtdraht im Augenblick seines Einbringens in die bzw. Entferriens aus der Glühbirne.Fig. A shows the new thread support frame with the one around the central support looped light wire at the moment of its introduction into or removal from the lightbulb.

Abb.3 zeigt die obere Fadentraglinse im Querschnitt. Auf der Mittelstütze c sitzt die Linse d mit den festgeklemmten Leuchtdrahtenden e. Die Linse d selbst ist in der Rille f um die Mittelstütze c drehbar.Fig. 3 shows the upper thread-carrying lens in cross-section. The lens d with the light-wire ends e clamped onto it sits on the center support c. The lens d itself is rotatable in the groove f around the central support c.

Der sich beim Wiederherstellen einer Glühlampe mittels des neuen Fadentraggestelles abspielende Vorgang ergibt sich ohne weiteres aus-der Zeichnung.When restoring a light bulb by means of the new thread support frame The process taking place is readily apparent from the drawing.

PATENT-ANsPRUcH: Fadentraggestell für elektrische Glühlampen, auswechselbar, zusammenlegbar und durch ein verhältnismäßig enges Loch an der Glühbirnenspitze hindurchführbar, gekennzeichnet durch eine auf dem oberen Ende der Mittelstütze (c) des Fadentraggestelles in achsialer Richtung drehbar angeordnete Fadentraglinse (d), die ein Herumwickeln des schraubenförmiken Glühfadens um die Mittelstütze .gestattet. PATENT CLAIM: Thread support frame for electric light bulbs, exchangeable, collapsible and passable through a relatively narrow hole at the bulb tip, characterized by a thread support lens (d) which is arranged on the upper end of the central support (c) of the thread support frame so that it can rotate in the axial direction and which winds around it of the helical filament around the center support.
