Description

Die Erfindung bezieht, -sich auf eine neuartige Ausbildung einer Sanduhr; -nach deren Prinzip heute besonders Eier-, Tee- wie auch in der Krankenbehandlung Pulsuhren gebräuchlich sind.The invention relates to a novel design of an hourglass; -according to their principle today, especially eggs, tea, as well as in the treatment of illnesses Heart rate monitors are common.

Der Erfindung liegt der Gedanke zugrunde, das Ablaufen der Uhr auch in gedämpftem Licht oder Dunkelheit sichtbar zu machen, was besonders bei Pulsuhren an Krankenbetten als angenehme Erleichterung empfunden wird und auch weitere Verwendungszwecke solcher Sanduhren, z. B. .in Dunkelkammern von photographischen Werkstätten, erschließt.The invention is based on the idea that the clock also runs down to make it visible in subdued light or darkness, which is especially true for heart rate monitors on hospital beds is perceived as a pleasant relief and also other uses such hourglasses, e.g. B. in darkrooms of photographic workshops.

Zu diesem Zweck wird erfindungsgemäß -vorgeschlagen, als Füllung für den gläsernen Sandbehälter ganz oder teilweise Leuchtsand oder Leuchtkristalle zu verwenden. Hierdurch -ist der Stand der Uhr auch hei Dunkelheit jederzeit ablesbar, ohne daß es hierzu der besonderen Einschaltung einer Lichtquelle bedarf.For this purpose it is proposed according to the invention as a filling for the glass sand container completely or partially to luminous sand or luminous crystals use. This means that the status of the clock can be read at any time, even in the dark, without the need for the special activation of a light source.

Während bei den bekannten Sanduhren der dünnwandige Sandbehälter entweder durch eine" teilweise Holzverkleidung oder durch Anordnung seitlicher Streben vor Beschädigungen geschützt worden ist, wird erfindungsgemäß vorgeschlagen, den Sandbehälter in eine zylindrische Glas- oder durchsichtige Kunststoffhülle einzuschließen, die oben und unten in einen verbreiterten Standsockel eingefügt ist. Die-Verwendung einer solchen durchsichtigen Schutzhülle birgt'den Vorteil in sich, daß der Ablaufvorgang der Uhr in allen Stadien und aus allen.Richkungen.voll sichtbar ist. Außerdem ermÖglicht sie eine äußerst- einfache Herstellung und Montage der Uhr.While in the known hourglasses the thin-walled sand container either by a "partial wood paneling or by arranging side struts Damage has been protected, it is proposed according to the invention, the sand container enclose in a cylindrical glass or clear plastic envelope the is inserted into a widened pedestal at the top and bottom. The usage Such a transparent protective cover harbors the advantage that the drainage process the clock is fully visible in all stages and from all directions. Also enables it is extremely easy to manufacture and assemble the clock.

In der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt.In the drawing, the subject of the invention is shown for example.

Die gezeigte Sanduhr ist durch eine Leuchtsandfüllung A des Glasbehälters B gekennzeichnet. Letzterer wird von einer durchsichtigen Hülle C umschlossen" die in die Standsockel D eingefügt ist. Selbst wenn die Uhr umgestoßen wird oder herunterfällt, schließen die vorstehenden Standsockel im -allgemeinen Beschädigungen der Schutzhülle und-somit-des- inneren Glasbehälters aus.The hourglass shown is characterized by a luminous sand filling A of the glass container B. The latter is enclosed by a transparent cover C, which is inserted into the stand base D. Even if the watch is knocked over or falls down, the protruding stand base in-general prevent damage to the protective cover and thus-the inner glass container.

Die Erfindung beschränkt sich nicht auf das beschriebene und dargestellte Ausführungsbeispiel, sondern dieses.soll lediglich den Grundgedanken und :das Anwendungsprinzip der Erfindung veranschaulichen.The invention is not limited to what is described and illustrated Embodiment, but this.soll only the basic idea and: the application principle of the invention.
