Description

Die vorliegende Erfindung betrifft eine Zentrifugenrotorvorrichtung bestehend aus einem Zentrifugenrotor und einem Deckel zum Verschließen eines Zentrifugenrotors, wie dieser beispielsweise aus der US-A-200400188928 bekannt ist.The present invention relates to a centrifuge rotor device consisting of a centrifuge rotor and a lid for closing a centrifuge rotor, as this example from US-A-200400188928 is known.

Zentrifugen sind Geräte, mit denen Behälter Fliehkraft ausgesetzt werden können. Im Labor können so zum Beispiel Suspensionen in Reagenzgläsern behandelt werden, um den schwebenden Feststoff am Boden des Reagenzglases abzusetzen. Zentrifugen weisen in aller Regel einen Drehantrieb auf mit einer senkrechten Antriebswelle, auf den ein Rotor aufsetzbar ist. In dem Rotor sind zumeist Fächer vorgesehen, in die sich Behälter, welche zentrifugiert werden sollen, einsetzen lassen. Oft sind die Rotoren der Zentrifuge auswechselbar, um in einem der Rotoren Gefäßinhalte zu zentrifugieren, während andere Rotoren erst noch mit Behältern beladen werden oder mit schon zentrifugierten Behältern zur Weiterbearbeitung bereitstehen können.Centrifuges are devices with which containers can be exposed to centrifugal force. In the laboratory, for example, suspensions in test tubes can be treated to deposit the suspended solid at the bottom of the test tube. Centrifuges usually have a rotary drive with a vertical drive shaft on which a rotor can be placed. Fans are usually provided in the rotor, into which containers which are to be centrifuged can be inserted. Often the rotors of the centrifuge are interchangeable to centrifuge vial contents in one of the rotors, while other rotors are first loaded with containers or can be prepared with further centrifuged containers for further processing.

Weil zum Beispiel Reagenzgläser oberseitig offen in die Rotoren gesteckt werden, dient es unter anderem der Betriebssicherheit, die Behälter beim Zentrifugieren in dem Rotor in einem flüssigkeitsdichten Raum zu halten. Dieser Raum sollte andererseits zur einfachen Beladung möglichst gut zugänglich sein. Weil insbesondere im Labor oft mehrere Handgriffe gleichzeitig ausgeführt und die Zentrifugen trotzdem sorgfältig verschlossen werden müssen, ist es besonders vorteilhaft, Geräte mit möglichst wenig Handgriffen, mit möglichst wenig Betätigungsbewegung und möglichst mit nur einer Hand betriebssicher benutzen zu können. Diesbezüglich sind bekannte Zentrifugen verbesserungsbedürftig.For example, because test tubes are inserted openly into the rotors on the top side, among other things, it serves to ensure the reliability of keeping the containers in a liquid-tight space during centrifugation in the rotor. On the other hand, this space should be as accessible as possible for easy loading. Because in the laboratory in particular often performed several actions at the same time and the centrifuges still need to be carefully closed, it is particularly advantageous to be able to use devices with as few hand movements, with as little actuation movement and possibly with only one hand reliable. In this regard, known centrifuges are in need of improvement.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Deckel zum Verschließen eines Zentrifugenrotors zu schaffen, dessen Handhabung vereinfacht ist.The present invention has for its object to provide a lid for closing a centrifuge rotor, the handling is simplified.

Diese Aufgabe wird erfindungsgemäß von einer Zentrifugenrotorvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a centrifuge rotor device having the features of claim 1. Preferred embodiments of the invention are specified in the subclaims.

Erfindungsgemäß ist eine Zentrifugenrotorvorrichtung bestehend aus einem Zentrifugenrotor und einem Deckel zum Verschließen eines Zentrifugenrotors gekennzeichnet durch ein Bewegungsgewinde mit einem Steigungswinkel, welcher derart gewählt ist, dass, der Deckel nach dem Vorpositionieren auf dem Zentrifugenrotor durch das Eigengewicht des Deckels selbsttätig in eine Verschlussposition im Gewinde geführt rotiert (Verschlussmechanismus). Als bevorzugte Ausgestaltung dessen zeigt ein Verschlussmechanismus der erfindungsgemäßen Vorrichtung die verschlossene Endposition des Deckels auf dem Zentrifugenrotor, insbesondere durch ein schnappendes oder klackendes Geräusch, akustisch an.According to the invention, a centrifuge rotor device consisting of a centrifuge rotor and a lid for closing a centrifuge rotor is characterized by a movement thread with a pitch angle, which is selected such that, after pre-positioning on the centrifuge rotor, the lid is automatically guided by the weight of the lid into a closed position in the thread rotates (locking mechanism). As a preferred embodiment, a closure mechanism of the device according to the invention acoustically indicates the closed end position of the lid on the centrifuge rotor, in particular by means of a snapping or clicking sound.

Zum Beispiel kann ein erfindungsgemäßer Deckel um eine im wesentlichen senkrechte Achse - vorzugsweise die Drehachse des Rotors - rotationssymmetrisch sein und (ähnlich wie ein Kochtopfdeckel mit mittigem Knauf) einen zentralen Griffknauf aufweissen, mit dem sich der Deckel von oben auf den Rotor aufsetzen lässt. Wenn dann der Verschlussmechanismus zum Beispiel ein Bewegungsgewinde mit einem genügend großem Steigungswinkel ist, kann der Deckel nach dem Vorpositionieren am Eingang des Gewindes durch das Eigengewicht des Deckels selbsttätig in eine Verschlussposition im Gewinde geführt rotieren. Vorzugsweise umfasst der Verschlussmechanismus eine Arretierung der vollständig verschlossenen Position des Deckels - zum Beispiel am Ende des Gewindes. Auf diese Weise genügt es also bei dieser erfindungsgemäßen Ausgestaltung, den Deckel mit einer Hand am Griffknauf von oben auf den Rotor vorzupositionieren, dann loszulassen, so dass er von selbst abwärts in eine fast verschlossene Position rotiert, und schließlich am selben Griffknauf noch um wenige Grad weiterzudrehen, so dass der Deckel in dann flüssigkeitsdicht verschlossener Position arretiert.For example, a lid according to the invention may be rotationally symmetrical about a substantially vertical axis, preferably the axis of rotation of the rotor, and (similar to a cooking pot lid with central knob) have a central handle knob, with which the lid can be placed on the rotor from above. If, for example, the closure mechanism is a movement thread with a sufficiently large pitch angle, the lid can automatically rotate into a closed position in the thread after pre-positioning at the entrance of the thread by the weight of the lid. Preferably, the locking mechanism comprises a locking of the fully closed position of the lid - for example at the end of the thread. In this way, it is sufficient in this embodiment of the invention, the cover with one hand on the handle knob from above on the rotor vorzupositionieren, then let go, so that it rotates downwards in an almost closed position, and finally on the same handle knob still a few degrees continue to turn so that the lid is then locked in a liquid-tight closed position.

Die Arretierung kann formschlüssig sein, zum Beispiel, indem der Deckel vor dem Arretieren auf seinen Dichtungen, die die Dichtigkeit bewirken, aufsitzt und zum Beispiel gegen deren gummielastische Verformbarkeit dann über einen Arretierungsabsatz mit einem Zapfen in einem Arretierungshinterschnitt formschlüssig zu liegen kommt.The lock can be positive, for example, by the lid before locking on its seals, which cause the tightness, and for example against the rubber-elastic deformability then comes to rest form-fitting manner via a Arretierungsabsatz with a pin in a Arretierungshinterschnitt.

In Figur 1 ist ein Zentrifugenrotor 2 erkennbar, über dem ein Deckel 4 abgebildet ist, wie er von einer Hand (nicht dargestellt) eines Benutzers auf den Zentrifugenrotor 2 aufgesetzt wird. Der Zentrifugenrotor 2 weist eine Reihe gleichmäßig auf dem Rotorumfang verteilter Bohrungen oder Fächer 6 auf, wohinein sich Reagenzgläser (nicht dargestellt) schräg nach außen unten orientiert stecken lassen. Der Rotor ist insgesamt um eine senkrechte Achse 8 rotationssymmetrisch und weist mittig eine senkrechte, zentrale Bohrung 9 auf, durch die sich der Rotor 2 auf eine Zentrifugenantriebswelle (nicht dargestellt) für das Zentrifugieren aufstecken lässt.In FIG. 1 a centrifuge rotor 2 can be seen, above which a lid 4 is shown, as it is placed by a hand (not shown) of a user on the centrifuge rotor 2. The centrifuge rotor 2 has a row evenly on the rotor periphery Distributed holes or compartments 6, while test tubes (not shown) can be stuck obliquely outward oriented down. The rotor is rotationally symmetrical overall about a vertical axis 8 and has in the center a vertical, central bore 9 , through which the rotor 2 can be attached to a centrifuge drive shaft (not shown) for centrifuging.

Die Fächer 6 für Reagenzgläser sind durch eine große kreisrunde Öffnung 10 in der Oberseite des Rotors 2 zugänglich. Sie befinden sich auf der radialen Außenwand eines napfförmigen Raumes 11, der sich ringförmig um eine zentrische Nabe 12 herumerstreckt.The compartments 6 for test tubes are accessible through a large circular opening 10 in the upper side of the rotor 2 . They are located on the radial outer wall of a cup-shaped space 11 which extends in a ring around a central hub 12 .

In der Nabe 12 ist unterseitig die Bohrung 9 für eine Zentrifugenrotorantriebswelle angeordnet. Nach oben ragt die Nabe 12 gewissermaßen kreiszylindrisch aus der Öffnung 10 heraus und bildet dort ein wesentliches Element eines Verschlussmechanismus 14 des Deckels 4: Der in der Draufsicht kreisrunde Deckel 4 nämlich weist in seiner Mitte oberseitig einen kreiszylindrisch aufwärts ragenden Griffknauf 16 auf, welcher unterseitig hohl, also sozusagen die Form eines Bechers oder Hutes hat. Zum Beispiel von oben gegriffen, lässt sich der Knauf 16 mit dem Deckel 4 insgesamt auf das obere Ende 18 der Nabe 12 aufsetzen und so vorpositionieren. Ohne weitere Drehbewegung erst einmal fällt der Deckel 4 aufgrund seines Eigengewichts entlang der senkrechten Achse 8 senkrecht nach unten mit dem becherförmigen Knauf 16 über das obere Ende 18 der Nabe 12, bis drei radial nach innen in dem becherförmigen Knauf vorspringende Gewindezapfen 20, welche gleichmäßig auf dem Umfang des Innenraums 22 des becherförmigen Knaufs 16 verteilt sind, auf der Oberkante des oberen Endes 18 der Nabe 12 zu liegen kommen.In the hub 12 , the bore 9 is arranged for a centrifuge rotor drive shaft on the underside. Upwards, the hub 12 protrudes out of the opening 10 to a certain extent circular cylindrical and forms an essential element of a closure mechanism 14 of the lid 4: The lid 4, which is circular in plan view, has a circular-cylindrical upwardly protruding handle knob 16 at its upper side, which is hollow on the underside , so to speak, has the shape of a mug or hat. For example, gripped from above, can the knob 16 with the cover 4 in total put on the upper end 18 of the hub 12 and so pre-position. Without further rotational movement, the lid 4 falls vertically downwardly with the cup-shaped knob 16 over the upper end 18 of the hub 12 due to its own weight along the vertical axis 8 until three threaded studs 20 projecting radially inwardly into the cup-shaped knob , which evenly the periphery of the interior 22 of the cup-shaped knob 16 are distributed to come to rest on the upper edge of the upper end 18 of the hub 12 .

So vorpositioniert, rutscht der Deckel 4 aufgrund seines Eigengewichtes weiter entlang der senkrechten Achse 8 nach unten und wird dabei von einem dreigängigen Gewinde 24 in eine Drehbewegung im Uhrzeigersinn versetzt. Das dreigängige Gewinde 24 in der Nabe 12 ist besonders gut in der räumlichen Ansicht von Figur 4 erkennbar. Das dreigängige Gewinde 24 mit Blick auf Figur 4 erstreckt sich in Form von drei spiralförmigen Nuten 24 auf dem Umfang der Nabe 12 spiralförmig nach unten. Die Nuten 24 haben eine solche Weite, dass die Gewindezapfen 20 im Innenraum des becherförmigen Knaufs 16 geführt, aber ohne zu klemmen, darin laufen können. So bewegt sich also der Deckel 4 durch sein Eigengewicht selbsttätig, sich um die senkrechte Achse 8 drehend, nach unten, bis seine O-Ring-Dichtung 26 (unterseitig am äußersten Deckelrand) auf dem oberen Rand der Rotoröffnung 10 zu liegen kommt. Diese Position des Deckels 4 auf dem Rotor 2 ist in Figur 2 erkennbar.Thus prepositioned, the lid 4 slips down due to its own weight along the vertical axis 8 down and is thereby offset by a three-start thread 24 in a rotary movement in a clockwise direction. The three-start thread 24 in the hub 12 is particularly good in the spatial view of FIG. 4 recognizable. The three-threaded thread 24 facing FIG. 4 extends in the form of three helical grooves 24 on the circumference of the hub 12 spirally downwards. The grooves 24 have such a width that the threaded pin 20 in the interior of the cup-shaped knob 16 out, but without clamping, can run in it. Thus, the lid 4 moves automatically by its own weight, rotating about the vertical axis 8 , down until its O-ring seal 26 (bottom side at the extreme edge of the lid) comes to rest on the upper edge of the rotor opening 10 . This position of the lid 4 on the rotor 2 is in FIG. 2 recognizable.

Erst in dieser Position muss der Benutzer zum abschließenden flüssigkeitsdichten Verschließen des Deckels 4 auf dem Rotor 2 den Knauf 16 nochmals (oberseitig am Deckel) greifen und um wenige Grad drehen, um den Deckel 4 auf dem Rotor 2 zu arretieren: Denn wieder mit Blick auf Figur 4 ist erkennbar, dass als Verschlussmechanismus die Nuten 24 des dreigängigen Gewindes an ihrem unteren Ende eine Arretierposition 27 für den Gewindestift 20 hinter einem Absatz 28 aufweisen. Durch aktives Weiterdrehen des Deckels 4, geführt durch seine Gewindezapfen 20 in den Gewindegängen 24 überwinden nun die Gewindezapfen 20 die Absätze oder "Buckel" 28 gegen die Vorspannung der gummielastischen Dichtung 26, die in eine Dichtungsnut 30 am äußeren Rand der Rotoröffnung 10 flüssigkeitsdicht gedrückt wird. Hinter den Buckeln 28 liegen die Gewindezapfen 20 dann formschlüssig arretiert in den Arretierpositionen 27 am Ende der Gewindegänge 24. Only in this position, the user must for the final liquid-tight closing of the lid 4 on the rotor 2, the knob 16 again (top side of the lid) grab and turn by a few degrees to lock the cover 4 on the rotor 2 : Because again looking up FIG. 4 It can be seen that as a locking mechanism, the grooves 24 of the three-start thread have a locking position 27 for the threaded pin 20 behind a shoulder 28 at its lower end. By active further rotation of the lid 4, guided by its threaded pin 20 in the threads 24 now overcome the threaded pin 20 paragraphs or "humps" 28 against the bias of the rubber-elastic seal 26 which is pressed liquid-tight in a sealing groove 30 at the outer edge of the rotor opening 10 , Behind the bosses 28 , the threaded pins 20 are then positively locked in the locking positions 27 at the end of the threads 24th
