Description

Zuentlastunaen für schmiegsame Elektro-Wärmeßeräte (Heizkissen). 1.) Zweck der Erfindung : Die in den VDE-Vorschriften 0785 (schmiegsame Elektro-Wärme- geräte) § 29 vorgeschriebene Zugentlastungsprufung setzt eine erhebliche Festigkeit der verwendeten Textilien voraus. Da die als Heizeinlage verwendeten Materialien (in der Regel Feudel, Filz usw.) dieser Prüfung nicht standhalten, so wird durch die nachstehend beschriebene Zugentlastung erreicht, daß durch diese die in den VDE-Prüfbestimmungen geforderten Bedingungen erfüllt werden. Relief for pliable electrical heating devices (heating pads). 1.) Purpose of the invention: The VDE regulations 0785 (flexible electrical heating devices) Section 29 of the prescribed strain relief test sets a considerable strength of the textiles used. There the materials used as the heating insert (usually Feudel, Filz, etc.) cannot withstand this test, so will achieved by the strain relief described below, that through this the required in the VDE test regulations Conditions are met.

2. ) Aufgabe der Erfindung : Durch das in die Heizeinlage eingefügte Leinenband (oder anderer Stoff als Träger), nach der aus dem Modell hervorgehenden Anordnung, den an der Zuleitung ausgeführten Zug aufzunehmen. 3.) Bernndun des Fortschrittes : --, Bei den bisher bekannten Bauarten der schmiegsamen Electro- Wármegeräte, z. B. elektrische Heizkissen, ist die Zuleitung an der Einfuhrungsstelle auf die Heizeinlage aufgenäht oder auf andere Art mit dieser verbunden. Ein an der Zuleitung ausgeübter Zug belastet die gesamte Fläche der Heizeinlage. Besonders stark ist diese Belastung an der Befestigungsstelle und es besteht die Gefahr, daß bei nicht genügender Festigkeit der Heizeinlage diese an der beschriebenen Stelle defekt wird. 2.) Object of the invention: Using the linen tape (or other material as a carrier) inserted into the heating insert, according to the arrangement shown in the model, to absorb the train carried out on the supply line. 3.) Bernndun of progress: -, With the previously known types of pliable electro- Heating devices, e.g. B. electric heating pads, is the lead sewn onto the heating insert at the point of introduction or connected with this in another way. One on the supply line exerted tension loads the entire area of the heating insert. This load is particularly strong at the fastening point and there is a risk that if the strength is insufficient the heating insert it becomes defective at the point described.

4. ) Sohutzanspruch.4.) Insurance claim.

Die wie vor beschriebene Zugentlastung ist dadurch gekennzeichnet, daß durch das auf der einen Seite mit der Zuleitung fest verbundene Leinenband genügender Festigkeit, welches bis auf die der Zuleitungseinfiihrungsseite entgegengesetzte Kante der Heizeinlage hindurchgeführt und an diesem Ende an der der Heizeinlage befestigt wird, der Zug allein von diesem Leinenband aufgenommen wird und somit die Heizeinlage und die inneren Verbindungsstellen völlig von den auftretenden Zugkräften entlastet wird. Dadurch ist es möglich, als Heizeinlage Materialien zu verwenden, die die für diesen Zweck angestrebte Weichheit haben, ohne die für die Zugentlastungsprobe erforderliche Festigkeit zu besitzen. The strain relief as described above is characterized by that by the linen tape firmly connected to the supply line on one side, it is more sufficient Strength, which is opposite to the side of the supply line entry Edge of the heating insert passed through and at this end on the the Heating insert is attached, the train is absorbed by this linen tape alone and thus the heating insert and the internal connection points completely from the occurring Tensile forces is relieved. This makes it possible to use materials as a heating insert use that have the softness desired for this purpose, without that for the Strain relief specimen to have the required strength.
