Description
Die vorliegende Erfindung betrifft eine Sanduhr, die neben feinkörnigem Material mit einer Flüssigkeit gefüllt ist.The present invention relates to a Hourglass, which in addition to fine-grained material with a Liquid is filled.
Sanduhren, insbesondere als Eieruhren oder als Zeittaktuhren zur Abgrenzung von Zeiteinheiten beim Telefonieren, sind jedermann bekannt. Ein in der Mitte eingeschnürter Hohlkörper, der zumeist aus Glas besteht, enthält Sand, der in einer bestimmten Zeit von einer Teilkammer in die andere rieselt. Bekannt ist auch schon eine Sanduhr (DE-AS 23 61 308), bei der zur Beseitigung von statischen Aufladungen des Sandes sowie zur Verlängerung der Ablaufzeit das Gefäß der Sanduhr neben Sandkörnern mit einer Flüssigkeit gefüllt ist. Weiterhin ist eine Zeitspannenmeßvorrichtung bekannt (DE-OS 34 13 062), bei der sich in einem mit einem Strömungsmittel gefüllten Kanal eine Kugel oder eine Gasblase von anderem spezifischem Gewicht als das Strömungsmittel unter dem Einfluß der Schwerkraft nach oben bzw. nach unten bewegt.Hourglasses, especially as egg clocks or as Time clocks for the delimitation of time units at Making calls is known to everyone. One in the middle constricted hollow body, which mostly consists of glass, contains sand that in a certain time of one Partial chamber trickles into the other. It is already known an hourglass (DE-AS 23 61 308), for the elimination of static charges on the sand and Extend the expiration time next to the vessel of the hourglass Grains of sand are filled with a liquid. Farther a time span measuring device is known (DE-OS 34 13 062), in which one with one Fluid filled a ball or a channel Gas bubble of a specific gravity other than that Fluid under the influence of gravity moved up or down.
Die Erfindung hat sich die Aufgabe gestellt, eine Sanduhr zu schaffen, die bei Werbe- und Geschenkartikeln, Andenken usw. einen besonderen Verblüffungs- und Aufmerksamkeitseffekt erzielt. Die Lösung der Aufgabe sieht vor, daß die Flüssigkeit spezifisch schwerer als das feinkörnige Material ist. Dadurch entsteht eine "umgekehrte" Sanduhr, bei der das feinkörnige Material scheinbar entgegen der Schwerkraft von unten nach oben rieselt.The object of the invention is to create an hourglass that is used in advertising and Gift items, souvenirs, etc. a special one Stunning and attention effect achieved. The Solving the problem provides that the liquid is specifically heavier than the fine-grained material. This creates an "inverted" hourglass, in which the fine-grained material apparently against gravity trickles from bottom to top.
Zur Realisierung der Erfindung benötigt man demnach eine Flüssigkeit, feinkörniges Material mit geringerem spezifischem Gewicht als die Flüssigkeit und eine geschlossene Hohlkammer mit einer für Sanduhren typischen Einschnürung.To implement the invention one needs therefore a liquid with fine-grained material lower specific gravity than the liquid and a closed cavity with one for hourglasses typical constriction.
Als feinkörniges Material werden wegen des erforderlichen niedrigeren spezifischen Gewichtes zweckmäßigerweise Partikel auf der Basis von Kunststoff, (Kunst-) -Harz, wachsartiger Substanzen, kristallisierender organischer Stoffe oder mikroverkapselter Gase, Flüssigkeiten oder Feststoffe verwendet. Mikrokapseln sind kugelig und daher besonders rieselfähig.As a fine-grained material because of the required lower specific weight expediently particles based on plastic, (Synthetic) resin, waxy substances, crystallizing organic substances or microencapsulated gases, liquids or solids used. Microcapsules are spherical and therefore special free-flowing.
In Weiterbildung der Erfindung kann außerdem vorgesehen sein, daß das feinkörnige Material farbig oder fluoreszierend eingefärbt ist. Auch die verwendeten Flüssigkeiten können auf diese Weise ausgebildet sein. Die Flüssigkeit soll möglichst niedrigviskos sein und das feinkörnige Material weder auf- noch anlösen oder anquellen, so daß es nicht zu Aggregationserscheinungen kommt.In a further development of the invention can also be provided that the fine-grained material is colored or is colored fluorescent. Even the ones used Liquids can be formed in this way. The liquid should be as low viscosity as possible and that fine grain material neither dissolve nor dissolve or swell so that it does not cause aggregation is coming.
Die Zeichnung zeigt den prinzipiellen Aufbau einer umgekehrten Sanduhr. Ein Grundkörper 1 besitzt zwei Deckel 2 und eine Einschnürung 3. Er ist mit einer Flüssigkeit 4 und feinkörnigem Material 5 gefüllt.The drawing shows the basic structure of an inverted hourglass. A base body 1 has two lids 2 and a constriction 3 . It is filled with a liquid 4 and fine-grained material 5 .
Zweckmäßigerweise stellt man zunächst, vorzugsweise im Kunststoff-Spritzguß, einen transparenten Hohlkörper als Grundkörper 1 her mit einer Einschnürung in der Mitte und symmetrisch an den Enden der Teilräume angeordneten Öffnungen. Eine Öffnung verschließt man vorzugsweise durch Ultraschallschweißen mit einem vorzugsweise mitgespritzten Deckelteil. Dann füllt man das feinkörnige Material ein und danach die Flüssigkeit. Anschließend wird auch diese Öffnung verschlossen, und zwar so, daß Lufteinschlüsse vermieden werden.Appropriately, first, preferably in plastic injection molding, a transparent hollow body is produced as base body 1 with a constriction in the middle and openings arranged symmetrically at the ends of the subspaces. An opening is preferably closed by ultrasonic welding with a cover part which is preferably injection-molded. Then you fill in the fine-grained material and then the liquid. Then this opening is also closed in such a way that air pockets are avoided.
Das feinkörnige Material siebt man vorher wie bei herkömmlichen Sanduhren auf eine bestimmte Korngrößenverteilung aus, d. h. zu grobe und zu feine Anteile werden eliminiert.The fine-grained material is sieved beforehand like in conventional hourglasses to a specific one Grain size distribution from, d. H. too coarse and too fine Shares are eliminated.
