Abstract

For hanging suspended ceilings which have carrying rails (5) having the cross-section of an inverted T and provided with a perforated longitudinal web (7), the hanger used has an upper, vertical hanger rod (1) and a lower, vertical hanger rod (3) which is vertically adjustable relative to the said upper rod. At its lower end, the lower hanger rod (3) has a hook-in eye (11) which is closed except for a hook-in gap (12), is hooked into a hole in the longitudinal web (7) of the carrying rail and is of approximately circular shape. The width (a) of the hook-in gap (12) is greater than the width (b) of that part of the longitudinal web (7) of the carrying rail which is above the hole. The hook-in eye (11) can only be hooked in and out of the longitudinal web (7) when the hanger rod (3) is brought into a position in which it slopes obliquely downwards. This prevents unintentional unhooking of the installed hanger. (Fig.1) <IMAGE>

Description

Die Erfindung betrifft einen Hänger für eine mit einem gelochten Längssteg versehene, im Querschnitt T-förmige Tragschiene einer Unterdecke, mit einem senkrechten Hängerstab, der an seinem unteren Ende einen in ein Loch des Tragschienen-Längsstegs einhängbaren Haken aufweist.The invention relates to a hanger for a supporting rail of a suspended ceiling provided with a perforated longitudinal web, which is T-shaped in cross section, with a vertical hanging bar which has at its lower end a hook which can be hung into a hole in the longitudinal rail web.

Im Querschnitt T-förmige Tragschienen zur Aufnahme von eingelegten Deckenplatten zur Bildung einer abgehängten Unterdecke sind in zahlreichen Ausführungsformen bekannt (DE-GM 19 14 290). Eine einfache Befestigungsart für diese Unterdecken besteht darin, die Tragschienen mittels Drähten an der Rohbaudecke zu befestigen, deren untere Enden durch die Löcher der Tragschienen gesteckt und zu einer Öse zusammengedreht werden (US-PS 3 369 332). Weil die Tragschienen einer Unterdecke nach der ersten, vorläufigen Montage in der Höhe ausgerichtet werden müssen, bereitet diese Art der Abhängung Schwierigkeiten, weil eine nachträgliche Höheneinstellung nach der Bildung der Ösen an den Drahtenden kaum oder nur mit verhältnismäßig großem Arbeitsaufwand möglich ist (US-PS 2 915 275).In cross-section T-shaped support rails for receiving inserted ceiling panels to form a suspended ceiling are known in numerous embodiments (DE-GM 19 14 290). A simple type of fastening for these suspended ceilings is to fasten the mounting rails to the structural ceiling using wires, the lower ends of which are inserted through the holes in the mounting rails and twisted together to form an eyelet (US Pat. No. 3,369,332). Because the mounting rails of a suspended ceiling have to be aligned in height after the first, preliminary assembly, this type of suspension creates difficulties, because subsequent height adjustment after the formation of the eyelets at the wire ends is hardly possible or only with a relatively large amount of work (US-PS 2 915 275).

Um diese Schwierigkeiten zu überwinden, wurden zahlreiche Ausführungsformen von Hängern für Unterdecken geschaffen, die eine einfache und bequeme Längenverstellung der Hänger auch noch nach der vorläufigen Montage ermöglichen. Bei einem bekannten Hänger der eingangs genannten Art (DE-GM 72 26 205) ist ein den unteren Hängerteil bildender senkrechter Hängerstab an seinem unteren Ende hakenförmig ausgebildet, so daß er in einfacher und bequemer Weise in ein Loch des Tragschienen-Längsstegs eingehängt werden kann. Derartige Hänger werden wegen der einfachen Anbringungsmöglichkeit der Tragschiene seit langem in großer Zahl verwendet.In order to overcome these difficulties, numerous embodiments of hangers for suspended ceilings have been created, which enable simple and convenient length adjustment of the hangers even after the preliminary assembly. In a known hanger of the type mentioned (DE-GM 72 26 205), a vertical hanger rod forming the lower hanger part is hook-shaped at its lower end, so that it can be hung in a hole in the mounting rail longitudinal web in a simple and convenient manner. Such hangers have been used in large numbers for a long time because of the easy attachment of the mounting rail.

Normalerweise übt die abgehängte Unterdecke auf die sie tragenden Hänger eine Zugbelastung aus. Wenn die Tragschiene aber angehoben wird, beispielsweise wenn eine Trennwand unter die Tragschiene gestellt wird, oder wenn bei der Montage der Unterdecke ein Anheben zur Höhenausrichtung der gesamten Unterdecke notwendig ist, besteht bei den bekannten Hängern die Gefahr, daß sich der Haken aus dem Tragschienen-Längssteg aushängt. Dasselbe gilt auch bei Auftreten von Winddruck, z. B. beim Öffnen der Türen. Diese Gefahr ist bei der beschriebenen Drahtösen-Montage zwar nicht gegeben, die aber wegen der umständlichen Montage und der praktisch fehlenden Nachstellmöglichkeit als nachteilig gilt.Normally, the suspended false ceiling exerts a tensile load on the hangers that carry it. However, if the mounting rail is lifted, for example if a partition is placed under the mounting rail, or if the ceiling is to be raised to align the entire ceiling with the installation of the suspended ceiling, there is a risk in known hangers that the hook will come out of the mounting rail. Longitudinal web detaches. The same also applies when wind pressure occurs, e.g. B. when opening the doors. This risk does not exist in the wire eyelet assembly described, but is considered disadvantageous because of the cumbersome assembly and the practically lacking adjustment facility.

Eine Abhilfe könnte bei den bekannten Hängern mit hakenförmigen Hängerstäben darin bestehen, den Haken nach der endgültigen Montage zuzubiegen, um ein unbeabsichtigtes Aushängen zu verhindern. Diese Maßnahme wäre aber sehr aufwendig, insbesondere wenn verhältnismäßig kräftige Hängerstäbe verwendet werden, die im montierten Zustand nicht mehr ohne weiteres gebogen werden können.A remedy for the known hangers with hook-shaped hanger bars could be to bend the hook after the final assembly in order to prevent unintentional unhooking. However, this measure would be very expensive, especially if relatively strong hanging rods are used, which can no longer be bent easily in the assembled state.

Aufgabe der Erfindung ist es daher, einen Hänger der eingangs genannten Art so auszubilden, daß einerseits zwar eine einfache Montage durch Einhängen in ein Loch des Tragschienen-Längsstegs ohne die Notwendigkeit einer nachfolgenden Verformung des Hängerstabs möglich ist, daß aber andererseits im montierten Zustand ein Aushängen des Hängerstabs formschlüssig verhindert wird.The object of the invention is therefore to design a hanger of the type mentioned in such a way that, on the one hand, simple assembly by hanging in a hole in the mounting rail longitudinal bar is possible without the need for subsequent deformation of the hanger rod, but that, on the other hand, unhooking in the assembled state of the hanger rod is positively prevented.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Haken eine bis auf einer Einhängespalt geschlossene Einhängeöse ist. In dieser Ausführung des Hakens als teilweise geöffnete Öse kann das Anbringen am Längssteg der Tragschiene durch einfaches Einhängen erfolgen, wobei der Hängerstab aber in einem schrägen Winkel zur.Senkrechten gehalten wird. Wenn der Hängerstab danach in die senkrechte Stellung gebracht wird, in der der Hänger an der Rohbaudecke angebracht ist, ist ein Aushängen nicht mehr möglich. Auch wenn die Tragschiene angehoben wird, kann die Eingehängeöse nur um ein geringes Maß nach einer der beiden Seiten ausweichen; dann befindet sich das Loch des Tragschienen-Längsstegs in einem Abschnitt der Einhängeöse, der so steil ansteigt, daß dieser Abschnitt der Einhängeöse den oberen und unteren Rand des Lochs berührt und ein weiteres Anheben der Tragschiene relativ zur Einhängeöse verhindert. Um den Hängerstab auszuhängen, müßte der Hängerstab vom Hänger gelöst bzw. der Hänger von der Rohbaudecke gelöst werden und schräg nach unten gehalten werden, oder die Tragschiene müßte um fast 180° gegenüber der Einhängeöse gedreht werden. Diese beiden Fälle können nicht eintreten, solange der Hängerstab mit dem Hänger und dieser mit der Rohbaudecke verbunden ist. Dadurch wird ein unbeabsichtigtes Aushängen bei Anheben der Tragschiene wirksam verhindert.This object is achieved in that the hook is a closed eyelet except for a suspension gap. In this version of the hook as a partially opened eyelet, it can be attached to the longitudinal web of the mounting rail by simply hanging it in, but the hanging rod is held at an oblique angle to the vertical. If the hanger rod is then brought into the vertical position, in which the hanger is attached to the structural ceiling, it is no longer possible to unhook it. Even if the mounting rail is raised, the hanging eyelet can only deviate slightly to one of the two sides; then the hole of the mounting rail longitudinal web is located in a section of the suspension eyelet that rises so steeply that this section of the mounting eyelet touches the upper and lower edge of the hole and prevents further lifting of the mounting rail relative to the mounting eyelet. In order to unhook the hanger rod, the hanger rod would have to be detached from the hanger or the hanger from the unfinished ceiling and held diagonally downwards, or the mounting rail would have to be turned by almost 180 ° relative to the hanging eye. These two cases cannot occur as long as the hanger bar is connected to the hanger and this to the shell. This effectively prevents accidental unhooking when lifting the mounting rail.

In Weiterbildung des Erfindungsgedankens ist vorgesehen, daß die Breite des Eingehängespalts mindestens gleich der Breite des Teils des Tragschienen-Längsstegs oberhalb des Lochs ist. Dadurch wird ein Einhängen ohne Verformung der Einhängeöse ermöglicht, wobei die Einhängeöse aber gleichwohl weitgehend geschlossen ist.In a further development of the inventive concept, it is provided that the width of the hanging gap is at least equal to the width of the part of the mounting rail longitudinal web above the hole. This enables a hooking in without deformation of the hooking eye, although the hooking eye is nevertheless largely closed.

Zweckmäßigerweise hat die Einhängeöse mindestens angenähert Kreisform, weil sich dann der an der Tragschiene eingehängte Hängerstab ohne die Gefahr eines Verklemmens leicht nach oben in die senkrechte Lage schwenken läßt.Appropriately, the hanging eyelet has at least approximately circular shape, because then the hanging rod suspended on the mounting rail can be easily pivoted upwards into the vertical position without the risk of jamming.

Die Einhängeöse wird bevorzugt so ausgeführt, daß sie in einer Ebene liegt, in der auch der sich.anschließende gerade Abschnitt des Hängerstabs liegt. Der Hängerstab ist daher nicht räumlich, sondern nur in einer Ebene gekrümmt, wodurch die Herstellung vereinfacht und der Platzbedarf bei der Lagerhaltung niedrig gehalten werden.The suspension eyelet is preferably designed so that it lies in a plane in which the straight section of the hanger rod that follows is also located. The hanging bar is therefore not spatially, but only curved in one plane, which simplifies production and keeps the space required for storage low.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel näher erläutert, das in der Zeichnung dargestellt ist.The invention is explained in more detail below using an exemplary embodiment which is illustrated in the drawing.

Es zeigt:

  • Fig. 1 einen an einer Rohbaudecke abgehängten Hänger, der eine Tragschiene unter Unterdecke trägt, und
  • Fig. 2 eine vergrößerte, perspektivische Darstellung des in die Tragschiene eingehängten unteren Endes des Hängers nach Fig. 1.
It shows:
  • Fig. 1 a suspended on a structural ceiling hanger, which carries a mounting rail under the false ceiling, and
  • 2 is an enlarged, perspective view of the lower end of the hanger according to FIG. 1 suspended in the mounting rail.

Der in Fig. 1 gezeigte, zweiteilige Hänger weist einen oberen Hängerstab 1 auf, der an einer Rohbaudecke 2 befestigt ist. Ein unterer Hängerstab 3 ist an einer zweifach abgewinkelten Blattfeder 4 befestigt, indem das mehrfach abgebogene obere Ende des Hängerstabs 3 durch zwei Löcher der Blattfeder 4 gesteckt ist. Die beiden Enden der Blattfeder 4 bilden in entgegengesetzter Richtung schrägstehende Verkantungsfedern 4a und 4b, die jeweils in einer Bohrung den oberen Hängerstab 1 aufnehmen. Wenn die beiden Verkantungsfedern 4a und 4b gegeneinander gedrückt werden, kann die Blattfeder 4 im Hängerstab 1 verschoben werden. Werden die Verkantungsfedern 4a und 4b losgelassen, so sind die beiden Hängerstäbe 1 und 3 in der gewünschten Höhenlage bzw. Längeneinstellung miteinander verbunden.The two-part hanger shown in FIG. 1 has an upper hanger bar 1, which is fastened to a structural ceiling 2. A lower hanger bar 3 is double angled leaf spring 4 attached by the multi-bent upper end of the hanger rod 3 is inserted through two holes in the leaf spring 4. The two ends of the leaf spring 4 form oblique canting springs 4a and 4b in the opposite direction, each of which receives the upper hanger rod 1 in a bore. If the two canting springs 4a and 4b are pressed against each other, the leaf spring 4 can be moved in the hanging bar 1. If the canting springs 4a and 4b are released, the two hanging bars 1 and 3 are connected to one another in the desired height or length setting.

Eine im Querschnitt T-förmige Tragschiene 5 einer Unterdecke weist waagrechte Tragflansche 6 und einen nach oben ragenden Längssteg 7 auf, der beim dargestellten Ausführungsbeispiel zwei längsverlaufende Wulste 8, 9 besitzt.A cross-sectionally T-shaped support rail 5 of a false ceiling has horizontal support flanges 6 and an upwardly projecting longitudinal web 7 which, in the exemplary embodiment shown, has two longitudinal beads 8, 9.

Zwischen den beiden Wulsten 8, 9 sind in regelmäßigen Abständen entlang der Tragschiene 5 Löcher 10 angeordnet, in die jeweils der Hängerstab 3 eingehängt ist.Between the two beads 8, 9 5 holes 10 are arranged at regular intervals along the mounting rail, in each of which the hanging bar 3 is suspended.

Zu diesem Zweck ist der Hängerstab 3 an seinem unteren Ende mit einer Einhängeöse 11 versehen, die angenähert Kreisform hat. Die Einhängeöse 11 ist nicht vollständig geschlossen, sondern weist einen Einhängespalt 12 auf, dessen Breite a beim dargestellten Ausführungsbeispiel größer als die Breite b des über dem Loch 10 liegenden Teils des Tragschienen-Längsstegs 7 ist, wobei das Maß b vorzugsweise die größtmögliche Breite dieses Teils des Längsstegs 7 ist, um das Einhängen des Hängerstabs 3 zu erleichtern. Die für die Breite a des Einhängespalts 12 maßgebende Breite b kann aber auch so bemessen werden, daß sie die kleinste Breite des über dem Loch 10 liegenden Längsstegabschnitts darstellt; auch dann kann die Einhängeöse 11 noch eingehängt werden.For this purpose, the hanging rod 3 is provided at its lower end with a hanging eye 11, which has an approximately circular shape. The suspension eye 11 is not completely closed, but has a suspension gap 12, the width a of which, in the exemplary embodiment shown, is greater than the width b of the part of the longitudinal rail web 7 located above the hole 10, the dimension b preferably being the largest possible width of this part of the longitudinal web 7 is to facilitate the hanging of the hanging bar 3. The width b decisive for the width a of the suspension gap 12 can, however, also be dimensioned such that it represents the smallest width of the longitudinal web section lying above the hole 10; even then the suspension eye 11 can still be attached.

Wie man aus Fig. 2 erkennt, liegt die Einhängeöse 11 mit dem geraden Abschnitt des Hängerstabs 3 in einer gemeinsamen Ebene.As can be seen from FIG. 2, the hanging eye 11 lies with the straight section of the hanging bar 3 in a common plane.
