HeizgestellHeating rack
Bekannt ist eine Vorrichtung zur teilweisen Abschirmung eines zu erwärmenden Behältnisses, etwa eines Glaskolbens, gegenüber einer offenen Flamme (DE-GM 79 11230.4); diese bekannte Vorrichtung besteht aus einer Glaskeramik-Platte.A device for partially shielding a container to be heated, such as a glass bulb, is known an open flame (DE-GM 79 11230.4); this known device consists of a glass ceramic plate.
Diese Glaskeramik-Platte muß hierbei bei waagerechter Ebene derart gehaltert werden, daß unter ihr der Gasbrenner aufgestellt werden kann und das zu erwärmende Behältnis auf der Oberseite ruht.This glass ceramic plate must be held at a horizontal level in such a way that the gas burner is placed under it and the container to be heated rests on the top.

Gegenstand der Neuerung ist ein neuartiges Heizgestell, bei welchem ebenfalls eine Glaskeramikplatte entsprechend dem genannten DEGM mitverwendet wird, das jedoch gleichzeitig eine sichere und vorteilhafte Halterung für diese Platte bietet.The object of the innovation is a new type of heating frame, which also has a glass ceramic plate according to the called DEGM is also used, but at the same time offers a secure and advantageous holder for this plate.
Das Heizgestell besitzt einen Rahmen, der die Platte trägt. An der Vorderseite des Rahmens sind mindestens drei Beine befestigt, mit denen das Gestell auf dem Arbeitstisch steht.The heating rack has a frame that supports the plate. At least three legs are attached to the front of the frame, with which the frame stands on the work table.
Die Glaskeramikplatte kann z.B. rechteckig, quadratisch oder rund sein. Diesen Formen entsprechend ist der die Glaskeramikplatte tragende Rahmen rechteckig, quadratisch oder rund. The glass ceramic plate can, for example, be rectangular, square or round. In accordance with these shapes, the frame carrying the glass ceramic plate is rectangular, square or round.
Der Rahmen kann an seinem äußeren Rand hochgebördelt sein. Dieser Bördelrand verhindert eine seitliche Verschiebung der Platte, so daß diese nicht herunterrutschen kann.The frame can be crimped up at its outer edge. This bead prevents the Plate so that it cannot slip down.
Der Rahmen ist vorzugsweise glatt, wie z.B. bei den bekanntenThe frame is preferably smooth, such as in the known ones
Dreifüßen ,und ist z.B. mit aufgesteckten Klemmfedern versehen, deren Außenende hochgebogen ist. Diese Außenenden sichern die Glaskeramikplatte gegen seitliches Verrutschen und Herunterfallen. Tripods, and is provided with clip springs, for example, whose outer end is bent up. These outer ends secure the Glass ceramic plate to prevent slipping and falling to the side.
Figur 1 zeigt ein Heizgestell mit vier Beinen (1), die an einem quadratischen Rahmen (2) mit hochgebördeltem Außenrand (3) befestigt sind, auf dem die Glaskeramikplatte (4) ruht.Figure 1 shows a heating frame with four legs (1), which on a square frame (2) with a flanged outer edge (3) on which the glass ceramic plate (4) rests.
Figur 2 zeigt ein Heizgestell mit drei Beinen 10, mit dem an diesen befestigten glatten Rahmen (20), auf den die Klemmfedern (30) von der Innenseite her geschoben sind. Die Klemmfedern besitzen das hochgebogene Außenende (31). Die Glaskeramikplatte (30) ruht auf dem Rahmen mit den Klemmfedern und ist gegen seitliches Verschieben gesichert.Figure 2 shows a heating frame with three legs 10, with the this fixed smooth frame (20) on which the clamping springs (30) are pushed from the inside. The clamp springs have the curved outer end (31). The glass ceramic plate (30) rests on the frame with the clamping springs and is secured against lateral displacement.
