Description
Stativ.Tripod.
Gegenstand der Erfindung ist ein Stativ, welches in jedem chemischen Laboratorium und als Zubehör für Glüh-, Schmelz- und Wärmeöfen usw. Verwendung finden kann. The invention is a tripod, which in each chemical Laboratory and as accessories for annealing, melting and heating furnaces etc. use can.
Bei den bislang bekannt gewordenen Stativen liegt das zu bearbeitende (erwärmende) Objekt (Reagenzglas) nur in bestimmter Höhe, die Heizquelle (Bunsenbrenner) kann das Objekt (Reagenzglas)-nur in bestimmter Höhe erreichen. Gemäß der Erfindung ist das Stativ treppenartig ausgebildet, so daß z. B. der das Reagenzglas tragende Rost auf eine der Stufen gelegt werden kann. The one to be worked on lies with the tripods that have become known so far (warming) object (test tube) only at a certain height, the heating source (Bunsen burner) can only reach the object (test tube) at a certain height. According to the invention the tripod is designed like a staircase, so that, for. B. the one carrying the test tube Grate can be placed on one of the steps.
Fig. I zeigt ein Ausführungsbeispiel des Stativs im Grundriß, Fig. 2 in der Ansicht und Fig. 3 teilweise in der Abwicklung. Fig. I shows an embodiment of the tripod in plan, Fig. 2 in the view and FIG. 3 partially in the development.
Das Stativs hat beliebig viele und hohe Abstufungen b, welche sich gegenüberliegen und nach einer Richtung verlaufen. Die Abstufungen b erhalten an der einen Seite einen kleinen Ansatz c, um das Abrutschen des Rostes d zu verhindern. Der Rost d ruht mit seinen Rippen e auf den Stufen b und kann durch einfaches Drehen belieig hoch oder niedrig gestellt werden, je nachdem man z. B. das Reagenzglas schnell oder langsam erwär-1nefl will. The tripod has any number of high gradations b, which opposite and run in one direction. The gradations b receive on a small shoulder c on one side to prevent the grate d from sliding off. The grate d rests with its ribs e on the steps b and can be easily turned be set arbitrarily high or low, depending on whether you z. B. the test tube heats up quickly or slowly.
Der Rost d hat an der einen Rippe e einen aus schlecht wärmeleitendem Material bestehenden Griff f. Die Rippen e des Rostes d sind untereinander mit einem Ring g verbunden, um seine seitliche Verschiebung zu verlîindern. The grate d has on one rib e one made of poorly thermally conductive Material existing handle f. The ribs e of the grate d are with one another with a Ring g connected to prevent its lateral displacement.
Das Stativ kann mit drei Füßen Jt versehen sein, um es für den Arbeitstisch zu verwenden, kann aber auch ohne diese als Einsatz für Glüh-, Schmelz- und Wärmeöfen Verwendung finden. The tripod can be provided with three feet to make it suitable for the work table to use, but can also be used without them as an insert for annealing, melting and heating furnaces Find use.
