Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • the glass ceramic plate can e.g. be rectangular, square or round.
  • the frame supporting the glass ceramic plate is rectangular, square or round.
  • 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.
  • 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.
