Abstract

As a safe and convenient support for a glass ceramic plate which is intended for use as a hot plate in laboratories, it being arranged at a suitable distance between the gas burner and the vessel to be heated, there is proposed a metallic support stand which consists of a frame (2) which rests on at least three legs (1) and which holds the glass ceramic plate (4) safely, for example by means of a high-bead outer rim (3) or by means of clips (30). <IMAGE>

Description

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, for example a glass bulb, from an open flame is known (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 on a horizontal plane in such a way that the gas burner can be 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 subject of the innovation is a new type of heating frame, in which a glass ceramic plate in accordance with the aforementioned DEGM is also used, but which 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 frame 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. DiesenFormen entsprechend ist der die Glaskeramik- platte tragende Rahmen rechteckig, quadratisch oder rund.The glass ceramic plate can e.g. be rectangular, square or round. Corresponding to these shapes, the frame supporting 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 flanged up at its outer edge. This flanged edge prevents the plate from shifting sideways so that it cannot slide down.

Der Rahmen ist vorzugsweise glatt, wie z.B. bei den bekannten Dreifüßen/und ist z.B. mit aufgesteckten Klemmfedern versehen, deren Außenende hochgebogen ist. Diese Außenenden sichern die Glaskeramikplatte gegen seitliches Verrutschen und Herunterfallen.The frame is preferably smooth, such as in the known D tripod feet / and is provided, for example, with clip-on springs, the outer end of which is bent up. These outer ends secure the glass ceramic plate against slipping and falling off to the side.

  • Figur 1 zeigt ein Heizgestell mit vier Beinen (1), die an einernguadratischen Rahmen (2) mit hochgebördeltem Außenrand (3) befestigt sind, auf dem die Glaskeramikplatte (4) ruht.FIG. 1 shows a heating frame with four legs (1) which are attached to 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.FIG. 2 shows a heating frame with three legs 10, with the smooth frame (20) attached to it, on which the clamping springs (30) are pushed from the inside. The clamping 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.
