The plate has a ball that is arranged in a lubricant reservoir.

Description

Die Erfindung betrifft eine Türoffenhalte- bzw. Arretierungsvorrichtung, die zum Beispiel für Kühlräume und Kühlmöbel bzw. Kühlschränke eingesetzt wird. Es geht hier darum, dass die Tür, zum Beispiel einer Kühlzeite, zum Entnehmen und Befüllen von Ware an einem vorgegebenen Öffnungswinkel ohne weitere Bedienungsvorgange wie zum Beispiel das Einsetzen eines Hakens oder einer Feder, arretiert werden kann, so dass ein behinderungsfreier Zugang in die Kühlzelle gewährleistet ist.The invention relates to a Türoffenhalte- or locking device, which is used for example for refrigerators and refrigerators or refrigerators. The point here is that the door, for example, a cooling time, for removing and filling of goods at a predetermined opening angle without further operations, such as the insertion of a hook or a spring, can be locked so that a disability-free access to the cold room is guaranteed.

Bei bisher bekannten Systemen wird eine gabelartige Vorrichtung im oberen Scharnier zwischen Tür und Türrahmen angebracht, durch die ein Stift auf der Tür geführt wird, bis dieser in einer Auskerbung der gabelartigen Vorrichtung arretiert. Diese Systeme unterliegen einer starken Reibung mit der Folge einer geringen Lebensdauer. Zudem kann dieses System nicht nachgerüstet werden, da an herkömmlichen Isolierglastoren und Rahmen keine Vorrichtungen zum Anbringen der Bauteile vorhanden sind. Zudem benötigt diese Lösung Raum in der oberen Horizontalen zwischen Tür und Rahmen, der dort meist nicht vorhanden ist. Diese Lösungen funktionieren nur hakelig und sind aufwendig herzustellenIn previously known systems, a fork-like device is mounted in the upper hinge between the door and the door frame, through which a pin is guided on the door until it locks in a notch of the fork-like device. These systems are subject to strong friction resulting in a short life. In addition, this system can not be retrofitted, since there are no devices for attaching the components to conventional insulating glass frames and frames. In addition, this solution requires space in the upper horizontal between door and frame, which is usually not there. These solutions only work hakelig and are expensive to produce

Andere Lösungen ( EP 0 111 019 ) setzen in das untere Türrahmenschamier eine Feder ein, die durch ihre Form an vorhandenen Bauteilen wie Turscharnierplatten angepasst ist, so dass die Tür durch die Feder im geöffneten Zustand arretiert wird. Auch hier entsteht beim Öffnungs- und Schließvorgang der Tür starke Reibung zwischen der Feder und der Platte, so dass es zu Materialermüdung der Feder, starkem Verschleiß bis zur Zerstörung der Feder kommt. Problematisch bei diesen Lösungen sind sowohl eine unkomfortable Haptik beim Arretieren als auch die damit einhergehende starke Geräuschentwicklung.Other solutions ( EP 0 111 019 ) insert into the lower door frame hinge a spring, which is adapted by its shape to existing components such as door hinge plates, so that the door is locked by the spring in the open state. Again, arises during the opening and closing of the door strong friction between the spring and the plate so that it comes to material fatigue of the spring, heavy wear to the destruction of the spring. The problem with these solutions are both an uncomfortable feel when locking and the associated strong noise.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine Tür-Arretierungsvorrichtung zu schaffen, die weitestgehend verschleißfrei arbeitet und eine lange Lebensdauer gewährleistet. Zudem soll die Erfindung ohne weiteren technischen Aufwand an bereits existierenden Türen und Rahmen einsetzbar sein, geräuschlos arbeiten und dem Bediener die Haptik einer Oberklasseautotür vermitteln.The specified in claim 1 invention is based on the problem to provide a door-locking device, which works largely wear-free and ensures a long life. In addition, the invention should be used without further technical effort on existing doors and frames, work noiselessly and give the operator the feel of a Oberklasseautotür.

Diese Probleme werden durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.These problems are solved by the features listed in claim 1.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass in den vorhandenen Türrahmen (2) und Türen (1) lediglich die zusätzliche Platte (5) mit der darin befindlichen Kugel (7) eingesetzt werden muss. Hierbei wird die Tatsache ausgenutzt, dass zum Beispiel marktübliche Kühlzellentüren und - rahmen stets die im Patentanspruch 1 aufgeführten Scharnierplatten (3/4) aufweisen, mit dem Vorteil, dass die Platten in die gängigen Systeme einzufügen sind bzw. nachrüstbar sind. Der geringfügige Raum für die Platte ist bereits vorhanden, da sämtliche marktüblichen Türen und Rahmen genügend Raum nach oben aufweisen, so dass am unteren Scharnier die Platte mit der Kugel eingesetzt werden kann, ohne dass am oberen Rahmen zusätzlicher Raum geschafft werden muss.The advantages achieved by the invention are in particular that in the existing door frame (2) and doors (1) only the additional plate (5) with the ball (7) therein must be used. In this case, the fact is exploited that, for example, standard commercial cell doors and - frame always listed in claim 1 hinge plates (3/4) have, with the advantage that the plates are to be inserted into the current systems or can be retrofitted. The small space for the plate is already there, since all commercially available doors and frames have enough space upwards, so that at the lower hinge, the plate can be used with the ball, without the upper frame additional space must be created.

Eine weitere vorteilhafte Ausgestaltung ergibt sich aus den Patenansprüchen 2 und 3. Die Tür liegt mit der Platte (3) im geschlossenen Zustand auf der Kugel (7) auf, beim Öffnen der Tür läuft die Platte der Tür über die Kugel und beim Erreichen eines vorgegebenen Öffnungswinkels der Tür, bevorzugt 90°, endet die Scharnierplatte der Tür, so dass sich die Tür geringfügig absenkt und im geöffneten Zustand von der Kugel und der Schamierplatte der Tür arretiert wird (FIGUR III) (FIGUR V).A further advantageous embodiment results from the patent claims 2 and 3. The door is with the plate (3) in the closed state on the ball (7), when you open the door, the plate of the door over the ball and when reaching a predetermined Opening angle of the door, preferably 90 °, ends the hinge plate of the door, so that the door slightly lowers and is locked in the open state of the ball and the hinge plate of the door (FIGURE III) (FIGURE V).

Beim Schließen wird die Tür Silber einen leichten Widerstand, der durch das Aufeinandertreffen von der Scharnierplatte (3) der Tür mit der Kugel (7) hervorgerufen wird, gedrückt und rollt sodann auf der Kugel nahezu widerstandfrei in den geschlossenen Zustand (FIGUR VI).When closing, the door silver is pressed a slight resistance, which is caused by the meeting of the hinge plate (3) of the door with the ball (7), and then rolls on the ball almost without resistance in the closed state (FIGURE VI).

Die Verwendung der Kugel (7) in Anspruch 3 gewährleistet die beabsichtigte komfortable und hochwertige Haptik und einen nahezu verschleißfreien Betrieb mit fast unbegrenzter Lebensdauer.The use of the ball (7) in claim 3 ensures the intended comfortable and high-quality feel and a nearly wear-free operation with almost unlimited life.

Eine weitere vorteilhafte Ausgestaltung findet sich in Anspruch 4, da die zylindrische Bohrung nicht nur das Lager der Kugel darstellt, sondern zudem als Schmiermittelreservofr nutzbar ist.A further advantageous embodiment can be found in claim 4, since the cylindrical bore is not only the bearing of the ball, but also available as Schmiermittelreservofr.

Ein Ausführungsbeispiel ist in den Figuren I - VI dargestellt und wird wie folgt näher beschrieben:

  • Figur I zeigt eine Glasisoliertür, scharnierartig angebracht.
  • Figur II zeigt alle Elemente der Erfindung und zwar die Tür (1), den Türrahmen (2), die Platte der Tür (3), die Platte des Rahmens (4), die neu aufzusetzende Platte (5), die zylindrische Bohrung in der neunen Platte (6), die dort eingebrachte Kugel (7) mit Reservoir (8) im nichtzusammengesetzten Zustand.
