Description

Die Erfindung betrifft ein insbesondere für Kühlraumtüren bestimmtes Türscharnier mit einem am Türrahmen zu befestigenden Rahmenbock und einem an der Tür zu befestigenden Türbock, die durch eine Scharnierachse miteinander verdrehbar verbunden sind, wobei auf der am Rahmenbock oder Türbock unverdrehbar gehaltenen Scharnierachse ein Stützlager angeordnet ist, auf dessen oberer Lagerfläche sich ein am Türbock bzw. Rahmenbock angeordnetes Auflager mit einer Auflagefläche abstützt.The invention relates in particular to a door hinge intended for cold room doors with a frame bracket to be fastened to the door frame and a door bracket to be fastened to the door, which are rotatably connected to one another by a hinge axis, a support bearing being arranged on the hinge axis held non-rotatably on the frame bracket or door frame whose upper bearing surface is supported by a support arranged on the door frame or frame support with a support surface.

Derartige Türscharniere sind bekannt. Sie sind dazu bestimmt, schwere Türen, insbesondere Kühlraumtüren zuverlässig zu tragen und in der Schließstellung in einer gegenüber dem Türrahmen abgedichteten Stellung zu halten.Such door hinges are known. They are designed to reliably carry heavy doors, especially cold room doors, and to hold them in the closed position in a position sealed against the door frame.

Insbesondere wegen des hohen Türgewichtes ist es unvermeidbar, daß sich die Tür nach längerem Gebrauch senkt, so daß die Türscharniere nachgestellt werden müssen, insbesondere wenn ein vorzeitiger Verschleiß der unteren Dichtungen vermieden werden soll. Bei den bekannten Türscharnieren ist es erforderlich, zum Zwecke der Nachstellung den Rahmenbock und/oder Türbock am Rahmen bzw. an der Tür zu versetzen, wozu die bekannten Türscharniere mit entsprechenden Langlöchern versehen sind.In particular because of the high door weight, it is inevitable that the door will lower after prolonged use, so that the door hinges have to be readjusted, especially if premature wear of the lower seals is to be avoided. In the known door hinges, it is necessary to move the frame bracket and / or door bracket on the frame or on the door for the purpose of readjustment, for which purpose the known door hinges are provided with corresponding elongated holes.

Der Erfindung liegt die Aufgabe zugrunde, ein Türscharnier der eingangs beschriebenen Art dahingehend weiterzuentwickeln, daß eine einfache Nachstellung des Türbockes gegenüber dem Rahmenbock in der Höhe möglich ist.The invention has for its object to develop a door hinge of the type described in such a way that a simple adjustment of the door frame compared to the frame bracket is possible in height.

Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß die Scharnierachse mit einem Gewindeabschnitt und Angriffsflächen für ein Handwerkzeug versehen und höhenverstellbar in einem Gewinde des Rahmenbockes oder Türbockes gehalten ist.The solution to this problem by the invention is characterized in that the hinge axis is provided with a threaded section and engagement surfaces for a hand tool and is held in an adjustable height in a thread of the frame bracket or door bracket.

Durch die erfindungsgemäße Ausgestaltung der Scharnierachse ist es möglich, diese entweder am Rahmenbock oder am Türbock mit Hilfe ihres Gewindeabschnittes in der Höhe nachzustellen, wozu es lediglich erforderlich ist, ein Handwerkzeug an die Angriffsflächen der Scharnierachse anzusetzen und diese zu verdrehen, so daß das auf der Scharnierachse gehaltene Stützlager in der Höhe verstellt wird. Da hierdurch gleichzeitig das auf der oberen Lagerfläche des Stützlagers aufliegende Auflager in der Höhe verstellt wird, ergibt sich auf besonders einfache Weise ein sehr feinfühliges Nachstellen der Tür, ohne daß die Befestigung des Türbockes an der Tür bzw. des Rahmenbockes am Rahmen gelöst werden muß.Due to the design of the hinge axis according to the invention, it is possible to adjust the height of this either on the frame bracket or on the door bracket with the aid of its threaded section, for which it is only necessary to attach a hand tool to the engagement surfaces of the hinge axis and to twist it so that it is on the Hinge axis held support bearing is adjusted in height. Since this simultaneously adjusts the height of the support resting on the upper bearing surface of the support bearing, a very sensitive adjustment of the door results in a particularly simple manner without the fastening of the door bracket to the door or the frame bracket to the frame.

Diese erfindungsgemäße Weiterbildung ist sowohl bei Türscharnieren einsetzbar, die mit einem Stützlager mit waagerechter Lagerfläche versehen sind, als auch bei Türen, deren Stützlager mit einer schräg verlaufenden Lagerfläche und deren Auflager mit einer entsprechend schräg ausgeführten Auflagerfläche versehen ist, so daß sich die Tür beim Verschwenken aus ihrer geschlossenen Stellung anhebt. Mit dieser an sich bekannten Ausführung wird eine besonders gute Abdichtung der Türunterkante gegenüber dem Rahmen in der geschlossenen Stellung erreicht.This further development according to the invention can be used both for door hinges which are provided with a support bearing with a horizontal bearing surface, and for doors whose support bearings are provided with an inclined bearing surface and whose supports are provided with a correspondingly inclined bearing surface, so that the door pivots when pivoted from their closed position. With this design, which is known per se, a particularly good sealing of the lower edge of the door with respect to the frame is achieved in the closed position.

Gemäß einem weiteren Merkmal der Erfindung kann die Scharnierachse als Schraube ausgebildet werden, auf deren Schraubenkopf das Stützlager aufliegt. Die mit dem Schraubenkopf nach unten weisende Schraube stellt somit nicht nur ein handelsübliches und damit preiswertes Bauteil zur Bildung der Scharnierachse dar, sondern dient gleichzeitig in besonders einfacher Weise zur Lagerung des Stützlagers.According to a further feature of the invention, the hinge axis can be designed as a screw, on the screw head of which the support bearing rests. The screw with the screw head pointing downward is thus not only a commercially available and therefore inexpensive component for forming the hinge axis, but also serves in a particularly simple manner for mounting the support bearing.

In an sich bekannter Weise wird auch beim erfindungsgemäßen Türscharnier das Stützlager durch Formschluß gegen Verdrehen gegenüber dem Rahmenbock bzw. Türbock gehalten, vorzugsweise mittels einer auf der Mantelfläche des Stützlagers ausgebildeten Mehrkantfläche, die in eine entsprechende Aussparung des Rahmenbockes bzw. Türbockes eingreift.In a manner known per se, the support bearing is also held in the door hinge according to the invention by positive locking against rotation relative to the frame bracket or door bracket, preferably by means of one on the lateral surface of the support bearing formed polygonal surface, which engages in a corresponding recess in the frame bracket or door bracket.

Um eine besonders einfache Verdrehsicherung für die Scharnierachse zu schaffen, wird mit der Erfindung weiterhin vorgeschlagen, den Schraubenkopf der als Scharnierachse dienenden Schraube durch eine auf den Rahmenbock bzw. Türbock aufsetzbare Kappe gegen Verdrehen zu halten. Diese Kappe ist erfindungsgemäß mit einer dem Schraubenkopf entsprechenden Aussparung versehen, so daß nach dem Aufsetzen der Kappe die die Scharnierachse bildende Schraube zuverlässig gegen Verdrehen am Rahmenbock bzw. Türbock gehalten ist.In order to provide a particularly simple anti-rotation device for the hinge axis, the invention further proposes to hold the screw head of the screw serving as the hinge axis against rotation by means of a cap which can be placed on the frame bracket or door bracket. This cap is provided according to the invention with a recess corresponding to the screw head, so that after the cap has been put on, the screw forming the hinge axis is held reliably against rotation on the frame bracket or door bracket.

Um ein unbefugtes Öffnen der verschlossenen Tür durch Manipulationen am Türscharnier zu verhindern, wird gemäß einem weiteren Merkmal der Erfindung die Kappe mittels einer bei geschlossener Tür abgedeckten Befestigungsschraube gegen Abnehmen gesichert.In order to prevent unauthorized opening of the closed door by manipulations on the door hinge, the cap is secured against removal by means of a fastening screw covered when the door is closed.

Mit der Erfindung wird schließlich vorgeschlagen, auf dem Gewindeabschnitt der Schraube eine Kontermutter anzuordnen; mit Hilfe dieser Kontermutter ist es möglich, die höhenverstellbare Scharnierachse der Erfindung auch während der Einstellarbeiten bei noch nicht angebrachter Kappe gegen Verdrehen zu sichern.Finally, the invention proposes to arrange a lock nut on the threaded section of the screw; With the help of this lock nut, it is possible to secure the height-adjustable hinge axis of the invention against twisting even during the adjustment work when the cap has not yet been attached.

Das anhand eines bevorzugten Ausführungsbeispiels dargestellte Türscharnier umfaßt einen an einem Rahmen R anzuschraubenden Rahmenbock 1 sowie einen an einer Tür T anzuordnenden Türbock 2, die durch eine Scharnierachse 3 miteinander verdrehbar verbunden sind. Beim Ausführungsbeispiel ist die Scharnierachse 3 unverdrehbar zwischen zwei Vorsprüngen 1a und 1b des Rahmenbockes 1 angeordnet. Auf ihrem mittleren Abschnitt ist ein Vorsprung 2a des Türbockes 2 verdrehbar gelagert.The door hinge shown on the basis of a preferred exemplary embodiment comprises a frame bracket 1 to be screwed onto a frame R and a door bracket 2 to be arranged on a door T, which are rotatably connected to one another by a hinge axis 3. In the exemplary embodiment, the hinge axis 3 is arranged non-rotatably between two projections 1a and 1b of the frame bracket 1. A projection 2a of the door frame 2 is rotatably mounted on its central section.

Sowohl der Rahmenbock 1 als auch der Türbock 2 wird sowohl am oberen als auch am unteren Ende jeweils mittels zweier, auf der Zeichnung nicht dargestellter Schrauben am Rahmen R bzw. an der Tür T angeschraubt. Zu diesem Zweck sind Rahmenbock 1 und Türbock 2 am oberen und unteren Ende jeweils mit einem Langloch 1c bzw. 2b versehen. In diese Langlöcher 1c bzw. 2b werden Anschraubplatten 4 eingesetzt, die im Schnitt in Fig. 2 zu erkennen sind. Diese jeweils zur Aufnahme zweier Befestigungsschrauben ausgebildeten Anschraubplatten 4 sind auf ihrer Unterseite gezahnt und wirken mit einer entsprechenden Zahnung im Bereich der Langlöcher 1c bzw. 2b zusammen, so daß eine feinfühlige Justierung sowohl des Rahmenbockes 1 am Rahmen R als auch des Türbockes 2 an der Tür T möglich ist.Both the frame bracket 1 and the door bracket 2 are screwed to the frame R and to the door T both at the upper and at the lower end by means of two screws, not shown in the drawing. For this purpose, frame bracket 1 and door bracket 2 are each provided with an elongated hole 1c and 2b at the upper and lower ends. Screw-on plates 4, which can be seen in section in FIG. 2, are inserted into these elongated holes 1c and 2b. These screw plates 4, each designed for receiving two fastening screws, are serrated on their underside and interact with a corresponding toothing in the area of the elongated holes 1c and 2b, so that a sensitive adjustment of both the frame bracket 1 on the frame R and the door bracket 2 on the door T is possible.

Die den Türbock 2 verdrehbar mit dem Rahmenbock 1 verbindende Scharnierachse 3 ist als Schraube mit einem die eigentliche Scharnierachse 3 bildenden Schraubenschaft 3a, einem Schraubenkopf 3b und einem Gewindeabschnitt 3c ausgeführt. Die Schraube ist von unten her in ein im oberen Vorsprung 1a des Rahmenbockes 1 ausgebildetes Gewinde 1d eingeschraubt. Zur Lagesicherung der Schraube ist eine Kontermutter 3d vorgesehen.The hinge axis 3, which rotatably connects the door bracket 2 to the frame bracket 1, is designed as a screw with a screw shaft 3a forming the actual hinge axis 3, a screw head 3b and a threaded section 3c. The screw is screwed from below into a thread 1d formed in the upper projection 1a of the frame bracket 1. A lock nut 3d is provided to secure the screw in position.

Auf der nach oben weisenden Unterseite des Schraubenkopfes 3b stützt sich ein vorzugsweise aus verschleißfestem Kunststoff hergestelltes Stützlager 5 ab, das mit einer schräg verlaufenden Lagerfläche 5a ausgebildet ist. Auf dieser Lagerfläche 5a liegt eine entsprechend schräg ausgeführte Auflagerfläche 6a eines Auflagers 6 auf, das unverdrehbar im Vorsprung 2a des Türbockes 2 angeordnet ist. Auch das Stützlager 5 ist unverdrehbar im Vorsprung 1b des Rahmenbockes 1 gehalten. Beim Ausführungsbeispiel erfolgt diese unverdrehbare Halterung durch Ausbildung von Mehrkantflächen auf der Mantelfläche des Stützlagers 5 bzw. Auflagers 6, die jeweils in entsprechend geformte Mehrkantaussparungen des Vorsprunges 1b bzw. 2a eingreifen.On the upward-facing underside of the screw head 3b, a support bearing 5, preferably made of wear-resistant plastic, is supported, which is formed with an inclined bearing surface 5a. On this bearing surface 5a there is a correspondingly inclined bearing surface 6a of a bearing 6, which is arranged non-rotatably in the projection 2a of the door frame 2. The support bearing 5 is held non-rotatably in the projection 1b of the frame bracket 1. In the exemplary embodiment this non-rotatable bracket by forming polygonal surfaces on the outer surface of the support bearing 5 or support 6, which each engage in appropriately shaped polygonal recesses of the projection 1b or 2a.

Aufgrund des schrägen Verlaufs sowohl der Lagerfläche 5a des unverdrehbar am Rahmenbock 1 gehaltenen Stützlagers 5 als auch der Auflagerfläche 6a des unverdrehbar am Türbock 2 gehaltenen Auflagers 6 wird die Tür T angehoben, wenn sie aus der in Fig. 1 dargestellten Schließstellung in Richtung ihrer Öffnungsstellung verschwenkt wird. Hierdurch wird erreicht, daß sich die Tür in der Schließstellung mit ihrer Unterkante in eine Stellung absenkt, in der die mit der Türunterkante zusammenwirkenden Dichtungen zuverlässig wirken.Due to the oblique course of both the bearing surface 5a of the support bearing 5 held non-rotatably on the frame bracket 1 and the bearing surface 6a of the support 6 held non-rotatably on the door bracket 2, the door T is raised when it pivots out of the closed position shown in FIG. 1 in the direction of its open position becomes. This ensures that the lower edge of the door in the closed position lowers into a position in which the seals interacting with the lower edge of the door act reliably.

Um bei der Erstmontage der Tür T eine korrekte Einstellung der Höhenlage zu erzielen und bei längerem Gebrauch eine abgesenkte Tür in der Höhe nachstellen zu können, ist es lediglich erforderlich, nach Lösen der Kontermutter 3d die die Scharnierachse 3 bildende Schraube zu verdrehen, indem ein passender Schraubenschlüssel an den Schraubenkopf 3b angesetzt wird. Durch dieses Verdrehen der Schraube verlagert sich das unverdrehbar im Vorsprung 1b des Rahmenbockes 1 gehaltene Stützlager 5 in der Höhe. Gleichzeitig wird die sich über das Auflager 6 und den Türbock 2 auf dem Stützlager 5 abstützende Tür T in der Höhe verstellt. Es ist somit auf besonders einfache Weise möglich, eine Einstellung bzw. Nachstellung der T in der Höhe vorzunehmen.In order to achieve a correct adjustment of the height at the first assembly of the door T and to be able to adjust the height of the door when it is in use for a longer period of time, it is only necessary to turn the screw forming the hinge axis 3 after loosening the lock nut 3d by a suitable one Wrench is attached to the screw head 3b. By rotating the screw, the support bearing 5 held non-rotatably in the projection 1b of the frame bracket 1 is displaced in height. At the same time, the height of the door T which is supported on the support bearing 5 via the support 6 and the door frame 2 is adjusted. It is therefore possible in a particularly simple manner to adjust or adjust the height of the T.

Um die die Scharnierachse 3 bildende Schraube in der jeweils gewählten Stellung unabhängig von der Kontermutter 3d festzuhalten, wird eine Kappe 7 verwendet, die in den Fig. 3 und 4 dargestellt ist. Diese vorzugsweise aus Kunststoff hergestellte Kappe besitzt eine Sechskantaussparung 7a, die den Abmessungen des Schraubenkopfes 3b entspricht. Sobald die Kappe 7 aufgesetzt ist, verhindert sie auf diese Weise formschlüssig eine Verdrehung der Schraube. Wie Fig. 3 erkennen läßt, wird die Kappe 7 durch eine Befestigungsschraube 7b am Vorsprung 1b des Rahmenbockes 1 befestigt, wozu die Kappe 7 mit einem die Befestigungsschraube 7b aufnehmenden Fortsatz 7c versehen ist. Dieser Fortsatz 7c und damit die Befestigungsschraube 7b sind bei geschlossener Tür T abgedeckt, so daß die Kappe 7 bei geschlossener Tür T nicht abgenommen werden kann. Auf diese Weise wird verhindert, daß durch Manipulationen an der die Scharnierachse 3 bildenden Schraube ein Öffnen einer geschlossenen Tür T möglich ist.In order to hold the screw forming the hinge axis 3 in the respectively selected position independently of the lock nut 3d, a cap 7 is used, which is shown in FIGS. 3 and 4. This cap, which is preferably made of plastic, has a hexagon recess 7a, which corresponds to the dimensions of the screw head 3b. As soon as the cap 7 is put on, it prevents the screw from twisting in a positive manner. As can be seen in FIG. 3, the cap 7 is fastened to the projection 1b of the frame bracket 1 by a fastening screw 7b, for which purpose the cap 7 is provided with an extension 7c receiving the fastening screw 7b. This extension 7c and thus the fastening screw 7b are covered when the door T is closed, so that the cap 7 cannot be removed when the door T is closed. That way prevents tampering with the screw forming the hinge axis 3 from opening a closed door T is possible.

Auch das obere, durch den Gewindeabschnitt 3c gebildete Ende der Schraube wird beim Ausführungsbeispiel durch eine Kappe 8 abgedeckt, die mit einem Fortsatz 8c zur Aufnahme einer Befestigungsschraube 8b versehen ist.The upper end of the screw formed by the threaded portion 3c is also covered in the exemplary embodiment by a cap 8 which is provided with an extension 8c for receiving a fastening screw 8b.
