US 911 162 A offenbart ein weiteres Trennglied mit Schmelzlot gemäß dem Oberbegriff von Anspruch 1. Die bekannten Schmelzlote werden in der Regel auf Körper, bestehend aus Kupferlegierungen, gelötet. Kupferlegierungen bilden durch Oxidation eine sogenannte Patina, die als Grünspan bekannt ist. Durch die giftigen Eigenschaften des Grünspans sind diese Thermotrennglieder für den Einsatz im Hygienebereich bzw. in der Gastronomie nicht geeignet. US 911 162 A discloses another fusible link isolator according to the preamble of claim 1. The known fins are usually soldered to bodies consisting of copper alloys. Copper alloys form by oxidation a so-called patina, which is known as verdigris. Due to the toxic properties of verdigris, these thermal isolators are not suitable for use in hygiene or gastronomy.

Bereiche, in denen eine aggressive Atmosphäre herrscht, führen zu einer schnellen Oxidation der Kupferlegierungen, so dass in diesen Bereichen besonders schnell Stoffe mit giftigen Eigenschaften entstehen. Deshalb sind die genannten Thermotrennglieder auch in diesen Anwendungsbereichen nicht einzusetzen.Areas in which an aggressive atmosphere prevails lead to a rapid oxidation of the copper alloys, so that in these areas particularly quickly substances with toxic properties. Therefore, the mentioned thermal isolators are not used in these applications.

Es ist daher Aufgabe der Erfindung, ein Thermotrennglied mit Schmelzlot zu entwickeln, welches diese Nachteile nicht aufweist und keine giftigen Stoffe bildet und somit in Hygienebereichen oder in der Gastronomie einsetzbar ist.It is therefore an object of the invention to develop a thermal isolator with fusible link, which does not have these disadvantages and does not form toxic substances and thus can be used in sanitary areas or in catering.

Diese Aufgabe wird durch ein Thermotrennglied nach den Merkmalen des ersten Patentanspruches gelöst.This object is achieved by a thermal isolator according to the features of the first claim.

Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.Subclaims give advantageous embodiments of the invention again.

Die erfindungsgemäße Lösung sieht ein Thermotrennglied mit Schmelzlot vor, welches für den Einsatz in der Feuerlöschtechnik geeignet ist und auf Zugspannung beansprucht wird, wobei dieses in einem vorgegebenen Temperaturbereich auslöst, ohne giftige Eigenschaften durch das Bilden von Grünspan zu entwickeln.The solution according to the invention provides a thermoterrelling element with fusible solder, which is suitable for use in fire-extinguishing technology and is subjected to tensile stress, this triggers in a predetermined temperature range, without developing toxic properties by the formation of verdigris.

Unter Schmelzlot werden alle Materialien verstanden, die ab einer bestimmten Temperatur ihren Aggregatzustand als Festkörper ändern, z.B. flüssig werden.Fused solder is understood as meaning all materials which, after a certain temperature, change their state of aggregation as a solid, e.g. become liquid.

Das erfindungsgemäße Trennglied besteht aus mindestens zwei durch einen Haltering verbundenen Grundkörpern, die an ihrer Verbindungsstelle einen Hohlraum aufweisen, in dem ein Schmelzlot angeordnet ist. Dieses Schmelzlot ist so ausgebildet, dass es den Hohlraum an der Verbindungsstelle ausfüllt. Hohlraum und Schmelzlot können in vorteilhafter Weise eine Stangen- oder eine Kugelform ausgebildet sein kann. Denkbar sind aber auch alle anderen geeigneten Formen wie eine Würfelform oder eine zylindrische Form. Um eine schnelle Wärmeübertragung auf den Schmelzkörper zu ermöglichen, weist der Grundkörper mindestens eine Rippe auf. Mehrere Rippen sind denkbar. Bei den Rippen kann es sich um zylindrische Rippen handeln. Damit der Grundkörper an den Zugelementen, beispielsweise Seilen, befestigbar ist, ist es vorteilhaft, wenn er beidseitig Ösen aufweist. Weiterhin ist es vorteilhaft, dass jeder der miteinander verbundenen Grundkörper eine ebene Fläche zueinander aufweisen. Der Haltering kann ein Metallring sein, der beide Grundkörper miteinander verbindet. Der Haltering bildet mit den Grundkörpern eine Spielpassung, so dass die Zugkräfte auf das Schmelzlot im Hohlraum wirken und die Grundkörper nicht durch den Haltering zusammengepresst werden.The separating member according to the invention consists of at least two main bodies connected by a retaining ring, which have at their connection point a cavity in which a fusible link is arranged. This fusible link is designed to fill the cavity at the junction. Cavity and fusible solder can be advantageously formed a rod or a spherical shape. Conceivable, however, are all other suitable shapes such as a cube shape or a cylindrical shape. In order to enable a quick heat transfer to the fusible element, the base body has at least one rib. Several ribs are conceivable. At the ribs it can be cylindrical ribs. So that the main body can be fastened to the tension elements, for example ropes, it is advantageous if it has eyelets on both sides. Furthermore, it is advantageous that each of the interconnected main body have a flat surface to each other. The retaining ring may be a metal ring, which connects the two bodies together. The retaining ring forms with the basic bodies a clearance fit, so that the tensile forces act on the fusible link in the cavity and the bodies are not pressed together by the retaining ring.

Der Grundkörper besteht aus einem mit dem Schmelzlot nicht verbundenen Material, ausgewählt aus Edelstahl, Keramik und Metallen mit verchromten oder vernickelten Oberflächen. Die erfindungsgemäße Lösung hat den Vorteil, dass bei aggressiver Atmosphäre und in Hygienebereichen keine Stoffe mit giftigen Eigenschaften entstehen.The base body consists of a material not connected to the fusible link selected from stainless steel, ceramics and metals with chrome-plated or nickel-plated surfaces. The solution according to the invention has the advantage that, in an aggressive atmosphere and in hygiene areas, no substances with toxic properties are formed.

Im Folgenden wird die Erfindung an einem Ausführungsbeispiel und einer Figur näher erläutert.In the following the invention will be explained in more detail with reference to an embodiment and a figure.

Die Figur zeigt das erfindungsgemäße Thermotrennglied in schematischer Darstellung im Teilschnitt, welches aus zwei gerippten Grundkörpern 1 besteht, die die gleiche Geometrie aufweisen. In einem Hohlraum 2, der von den Grundkörpern gebildet wird, ist ein geometrisch bestimmtes amorphes Stück, das Schmelzlot 3, eingelegt, welches bei einer vorgegebenen Temperatur schmilzt und sich nicht mit dem Grundkörper 1 löten lässt. Bei Überschreiten einer bestimmten Temperatur wird das Schmelzlot 3 flüssig. Beide Grundkörper 1 werden durch den Haltering 4 zusammengehalten, der mit dem Grundkörper 1 eine Spielpassung bildet. Ein Verschieben der Grundkörper gegeneinander wird durch das dazwischen befindliche Schmelzlot 3 verhindert. Die Grundkörper sind an beiden Enden mit Ösen 5 versehen, an denen über Seilzüge Zugbeanspruchungen auf das Schmelzlot 3 aufgebracht werden. Um die Umgebungstemperatur möglichst schnell auf das Schmelzlot 3 zu übertragen, sind am Grundkörper 1 Rippen 6 zur Wärmeaufnahme angeordnet. Bei Überschreiten einer bestimmten vorgegebenen Temperatur schmilzt das Schmelzlot 3 und die Grundkörper 1 werden durch die Zugbeanspruchung voneinander getrennt, indem diese durch den Haltering 4 gezogen werden.The figure shows the thermal isolator according to the invention in a schematic representation in partial section, which consists of two ribbed bodies 1, which have the same geometry. In a cavity 2, which is formed by the basic bodies, a geometrically determined amorphous piece, the fusible link 3, is inserted, which melts at a predetermined temperature and can not be soldered to the base body 1. When a certain temperature is exceeded, the melting solder 3 becomes liquid. Both base body 1 are held together by the retaining ring 4, which forms a clearance fit with the base body 1. A displacement of the main body against each other is prevented by the intervening fusible link 3. The bodies are provided at both ends with eyelets 5, where tensile stresses on the fusible link 3 are applied via cables. In order to transfer the ambient temperature as quickly as possible to the fusible link 3, ribs 6 are arranged on the main body 1 for heat absorption. When a certain predetermined temperature is exceeded, the melting solder 3 melts and the base bodies 1 are separated from one another by the tensile stress, by pulling them through the retaining ring 4.
