Description

Die Erfindung bezieht sich auf einen Fensterklarhalter, hei dem in bekannter Weise elektrische Energie durch Widerstandsheizung zur Lufterwärmung benutzt wird. Nach einem bekannten Vorschlag werden lange, verhältnismäßig dünne Rohre aus feuerfestem Material zentrisch in einer -Metallhülse von wesentlich größerem Querschnitt bzw. Durchnyesser mittels Federn nachgiebig gelagert. Diese Steinzeugrohre :besitzen zwei gegenüberliegende Kanäle zur Aufnahme von Heizdrähten, die in der einen Bohrung hin- und in der anderen zurückgeführt werden. Zwischen. @diiesen Kanälen in den Steinzeugrohren liegen noch weitere Kanäle zur Aufnahme von Stützstangen. Die komplizierteAusführung solcher Auftaugeräte mit ihren vielfach gebohrten Rohren ist naturgemäß teuer und bruchanfällig, so daß sich Geräte dieser Art nicht in die Praxis einzuführen vermochten.The invention relates to a window clear holder, namely in known way electrical energy is used by resistance heating to heat the air will. According to a known proposal, long, relatively thin tubes are made Refractory material centered in a metal sleeve with a significantly larger cross-section resp. diameter supported resiliently by means of springs. These clay pipes: own two opposite channels for receiving heating wires in one hole to be led back and forth in the other. Between. @these channels in the Vitrified clay pipes have additional channels for receiving support rods. The complicated execution Such thawing devices with their multiple drilled tubes are naturally expensive and prone to breakage, so that devices of this type could not be implemented in practice.

Die Erfindung verwendet demgegenüber in einfacher Weise eine einzige Heizspirale mit je einem Stecker an je einem Ende und mit einer Umkleidung aus an sich bekannten Isolierperlen und lagert dieses Aggregat in einem geschlitzten oder gelochten Rohr, wobei die an den Enden befindlichen Stecker je einen Bund aufweisen, mit dessen Hilfe ein sauberer und glatter Abschluß auf beiden Seiten des Heizelementes erreicht wird. Durch die Erfindung wird mit einfachen Mitteln ein Fensterklarhalter geschaffen, der billig herzustellen ist. Bei Beschädigungen, die praktisch nur an den aus feuerfestem Material bestehenden Isolierperlen auftreten könnten, ist eine Auswechslung der' heschädigten Perlen mit geringem Kosteil- und Arbeitsaufwand ohne weiteres möglich.In contrast, the invention uses a single one in a simple manner Heating coil with a plug at each end and with a covering known insulating beads and stores this unit in a slotted or perforated tube, the plugs at the ends each have a collar, with the help of which a clean and smooth finish on both sides of the heating element is achieved. The invention provides a clear window holder with simple means created that is cheap to manufacture. In the event of damage that is practically only at the insulating beads made of refractory material could occur is one Replacement of the 'damaged pearls with little cost and labor without further possible.

In Ader Zeichnung ist der Gegenstand der Erfindung in zwei Abbildungen beispielsweise dargestellt.In the drawing, the subject matter of the invention is shown in two figures for example shown.

Abb. i zeigt das Rohr mit den Durchtrittslöchern für die Warmluft, Abb. 2 die Heizspirale mit den Armierungen an den Enden.Fig. I shows the pipe with the passage holes for the warm air, Fig. 2 the heating coil with the reinforcements at the ends.

Wie aus der Zeichnung ersichtlich ist, .besteht der Fensterklarhalter aus demkohra mit Löchernd oder Schlitzen, dem Heizdraht c' und den um diesen aufgereihten Isolierperlen b. Die an den Enden der Heizspirale c angebrachten Stecker besitzen Ansatzstücke e mit Bunden f, so daß das Rohr a formschlüssig auf die Ansatzstücke e geschoben wird bzw. die Bunde f einen sauberen und glatten Abschluß ergeben.As can be seen from the drawing, the clear window holder consists of the pipe with holes or slots, the heating wire c 'and the insulating beads b lined up around it. The plugs attached to the ends of the heating coil c have extension pieces e with collars f, so that the pipe a is pushed onto the extension pieces e in a form-fitting manner or the collars f produce a clean and smooth finish.
