Abstract
Description
Die Erfindung betrifft einen Knotenabhänger für ein abgehängtes Deckensystem nach dem Oberbegriff des Patentanspruchs 1 sowie ein Deckensystem, in dem der Knotenabhänger verwendet wird.The invention relates to a node hanger for a suspended ceiling system according to the preamble of patent claim 1 and a ceiling system in which the node hanger is used.
Aus der
Die Einführung der Gewindestange durch die Öffnung in dem Steg ist relativ mühselig. Außerdem muss der Knotenabhänger mit einer Hand gehalten werden, während mit der anderen Hand die untere Gewindeschraube auf die Gewindestange geschraubt wird. Die Einstellung der Höhe ist erst nach Anbringung des Knotenabhängers möglich.The introduction of the threaded rod through the opening in the web is relatively cumbersome. In addition, the node hanger must be held with one hand, while the other hand, the lower threaded screw is screwed onto the threaded rod. The adjustment of the height is only possible after attachment of the node dependency.
Der Erfindung liegt die Aufgabe zugrunde, mit konstruktiv einfachen Mitteln einen Knotenabhänger zu schaffen, der auf einfache Weise installiert und in der Höhe eingestellt werden kann.The invention has for its object to provide a structurally simple means a node hanger that can be easily installed and adjusted in height.
Diese Aufgabe wird erfindungsgemäß durch einen Knotenabhänger mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen des erfindungsgemäßen Knotenabhängers sind Gegenstand der Patentansprüche 1 bis 6.This object is achieved by a node hanger with the features of claim 1. Advantageous developments of the node according to the invention are the subject of claims 1 to 6.
Ein Deckensystem, in dem der erfindungsgemäße Knotenabhänger verwendet werden kann, ist Gegenstand des Patentanspruchs 7 und in den Patentansprüchen 8 bis 10 vorteilhaft weitergebildet.A ceiling system in which the node hanger according to the invention can be used is the subject of claim 7 and in the claims 8 to 10 advantageously developed.
Der erfindungsgemäße Knotenabhänger kann auf einfache Weise an einer sich von der Decke nach unten erstreckenden Gewindestange befestigt werden. Hierzu wird die Gewindestange zwischen die beiden Aufhängehenkel geführt. Anschließend werden die Aufhängehenkel nach innen gebogen, bis die beiden freien Schenkel aufeinander liegen. Die Höhe der Aufhängung des Knotenabhängers ist auf einfache Weise einstellbar, da die untere Gewindeschraube auf die entsprechende Höhe eingestellt werden kann, bevor der Knotenabhänger auf die Gewindestange aufgesetzt wird. Durch die obere Gewindeschraube werden die beiden freien Schenkel gegeneinander gedrückt, wodurch der Knotenabhänger in seiner Position fixiert wird.The node hanger according to the invention can be fastened in a simple manner to a threaded rod extending downwards from the ceiling. To do this, the threaded rod is guided between the two suspension handles. Then the hanger handles are bent inwards until the two free legs lie on each other. The height of the suspension of the node suspension is easily adjustable, since the lower threaded screw can be adjusted to the appropriate height before the node hanger is placed on the threaded rod. Through the upper threaded screw, the two free legs are pressed against each other, whereby the node hanger is fixed in position.
Bei einer bevorzugten Ausführungsform weist der Befestigungsabschnitt zwei parallel zueinander verlaufende Seitenwände auf, mit denen jeweils ein Verbindungsschenkel eines Aufhängehenkels verbunden ist. In diesem Fall ist der freie Schenkel wenigstens eines Aufhängehenkels zweckmäßigerweise angrenzend an sein freies Ende um eine zur ersten und zweiten Biegelinie parallele dritte Biegelinie in Richtung der vertikalen Achse im stumpfen Winkel gebogen, wodurch ein Endschenkel am freien Ende gebildet wird. Der stumpfe Winkel ist so gewählt, dass der Endschenkel an dem Verbindungsschenkel des anderen Aufhängehenkels anliegt, wenn sich die Aufhängehenkel in der Befestigungsstellung befinden. Durch die Endschenkel werden die freien Schenkel in ihrer Position festgelegt.In a preferred embodiment, the attachment portion has two side walls running parallel to one another, to each of which a connecting leg of a suspension hook is connected. In this case, the free leg of at least one hanging loop is conveniently bent at an obtuse angle adjacent to its free end about a third bending line parallel to the first and second bending lines in the direction of the vertical axis, thereby forming an end leg at the free end. The obtuse angle is chosen so that the end leg rests against the connecting leg of the other suspension hanger when the hanger arms are in the fastening position. By the end legs, the free legs are fixed in position.
Zur Bildung eines einteiligen Biegeteils aus Blech erstrecken sich die Seitenwände vorzugsweise von den Seitenrändern eines Bodens des Befestigungsabschnitts vertikal nach oben.To form a one-piece sheet metal bent part, the side walls preferably extend vertically upward from the side edges of a bottom of the mounting portion.
Für eine sichere Verbindung mit einer entsprechenden Zarge ist im Eckbereich zwischen zwei angrenzenden Seitenwänden ein nach oben offener vertikaler Schlitz ausgebildet, der über dem Boden endet.For a secure connection with a corresponding frame an upwardly open vertical slot is formed in the corner between two adjacent side walls, which ends above the ground.
Bei einem Deckensystem mit dem erfindungsgemäßen Knotenabhänger befinden sich die Aufhängehenkel in der Befestigungsstellung. Durch die hierdurch gebildete Durchgangsöffnung geht eine entlang der vertikalen Achse verlaufende Befestigungsstange hindurch, an der in vertikaler Richtung einstellbare Einstellelemente angebracht sind, die an den entsprechenden freien Schenkeln oben bzw. unten anliegen.In a ceiling system with the node hanger according to the invention, the suspension hanger are in the attachment position. Through the passage opening formed thereby passes along the vertical axis extending mounting rod, are attached to the adjustable adjusting elements in the vertical direction, which bear against the corresponding free legs up or down.
Zweckmäßigerweise ist die Befestigungsstange eine Gewindestange, und die Einstellelemente werden von Gewindemuttern gebildet, die mit der Gewindestange in Eingriff stehen.Conveniently, the mounting rod is a threaded rod, and the adjusting elements are formed by threaded nuts, which are in engagement with the threaded rod.
Eine hervorragende Verbindung zwischen Knotenabhänger und Zarge wird ermöglicht, wenn die Zarge zwei parallel verlaufende Längsseitenwände und wenigstens eine an einer Seitenwand des Befestigungsabschnitts anliegende Stirnwand aufweist, wobei der Abstand der Längsseitenwände im Wesentlichen der Breite der entsprechenden Seitenwand entspricht. Auf der Seite der Stirnwand schließen jeweils an eine Längsseitenwand in Längsrichtung Laschen an. Zwischen den Laschen und der entsprechenden Längsseitenwand ist ein nach unten offener vertikaler Schlitz ausgebildet. Die Länge des Schlitzes entspricht dem Abstand zwischen dem unteren Ende des nach oben offenen Schlitzes im entsprechenden Eckbereich zwischen der Seitenwand, an der die Stirnwand anliegt, und der entsprechenden angrenzenden Seitenwand, und dem Boden des Befestigungsabschnittes. Die Zarge wird so eingesetzt, dass der Bereich unterhalb des nach oben offenen Schlitzes in den Eckbereichen jeweils in einen nach unten offenen Schlitz zwischen einer Längsseitenwand und einer Lasche eingreift.An excellent connection between node hanger and frame is made possible when the frame has two parallel longitudinal side walls and at least one fitting on a side wall of the mounting portion end wall, wherein the distance of the longitudinal side walls substantially equal to the width of the corresponding side wall. On the side of the end wall in each case close to a longitudinal side wall in the longitudinal direction tabs. Between the tabs and the corresponding longitudinal side wall, a downwardly open vertical slot is formed. The length of the slot corresponds to the distance between the lower end of the upwardly open slot in the corresponding corner region between the side wall against which abuts the end wall and the corresponding adjacent side wall, and the bottom of the mounting portion. The frame is inserted so that the area below the upwardly open slot engages in the corner regions in each case in a downwardly open slot between a longitudinal side wall and a tab.
Auch die Zarge wird vorteilhafterweise von einem einteiligen Biegeteil aus Blech gebildet.The frame is advantageously formed by a one-piece bent part made of sheet metal.
