"Klappbarer Luftkanal""Foldable air duct"
Die Neuerung bezieht sich auf Luftkanäle, die für den Transport in einfacher Weise zusammengeklappt werden können.The innovation relates to air ducts that can be easily folded up for transport.
Luftkanäle sind bekannt. Sie werden in der Regel wegen der feuerpolizeilichen Vorschriften aus Metall angefertigt. Zum Schutz gegen Korrosion ist das Metall verzinkt. Die Kanäle werden aus Blechtafeln oder -streifen durch Kanten oder Falzen zusammengesetzt bzw. in die gewünschte Form gebracht. Aus Kostengründen werden diese Arbeiten in der Regel in einer Werkstatt ausgeführt.Air ducts are known. They are usually because of the fire police Rules made of metal. The metal is galvanized to protect against corrosion. The channels are going out Metal sheets or strips assembled by edging or folding or brought into the desired shape. For cost reasons this work is usually carried out in a workshop.
Diese Kanäle haben aber den grossen Nachteil, dass sie beim Transport sehr viel Raum beanspruchen und damit relativ hohe Transportkosten verursachen.However, these channels have the major disadvantage that they during transport take up a lot of space and thus cause relatively high transport costs.
Es sind auch Ausführungsformen bekannt, bei denen in der Werkstatt lediglich eine Vorfertigung durchgeführt wird. In L-Form oder einzelnen Tafeln werden Halbfabrikate an die Verwendungsstellen geliefert und erst dort zu fertigen Kanälen zusammengefügt.There are also known embodiments in which in the workshop only a prefabrication is carried out. In L-shape or individual panels, semi-finished products are delivered to the point of use and only then assembled into finished ducts.
Diese Bearbeitungsformen haben den grossen Nachteil, dass das Zusammenfügen der Kanäle in die endgültige Form mit den auf Baustellen anfallenden höheren Kosten belastet ist gegenüber einer Fertigung in einer Werkstatt.These forms of processing have the major disadvantage that joining the ducts in their final form are burdened with the higher costs incurred on construction sites compared to production in a factory.
Die Neuerung dient dem Zweck, diese Mangel zu beheben. Luftkanäle werden danach aus Blechtafeln zusammengesetzt, die jeweils mit einem Scharnier verbunden sind.The purpose of the innovation is to remedy this deficiency. Air ducts are then assembled from sheet metal, each with connected by a hinge.
Dadurch können fertige Luftkanäle zusammengeklappt transportiert werden. Das Fertigstellen auf der Baustelle besteht lediglich im Auseinanderklappen und dem Fixieren des aufgeklappten Kanales durch die Monteure.This means that finished air ducts can be transported folded up. The completion on the construction site consists only in Unfold and fix the opened channel by the fitters.

Auf der Zeichnung ist die Neuerung aufgezeigt, und zwar stelltThe drawing shows the innovation, namely places

- die Kanalverbindungswinkel k - the duct connection angles k
und die Fixierungsstücke 3and the fixing pieces 3
Die Blechtafeln 1 sind an ihrer Längsseite mit einem Stehfalz versehen. In die Längsfalze zweier Blechtafeln wird das Scharnier 2 eingeführt und dann die Stehfalze geschlossen.The metal sheets 1 are provided with a standing seam on their long side. The hinge is inserted into the longitudinal folds of two metal sheets 2 inserted and then the standing seams closed.
Die Blechtafeln 1 können auch nur mit einer Abkantung versehen sein. Dann wird das Scharnier 2 mit Stehfalzen versehen.The metal sheets 1 can also only be provided with a bevel be. Then the hinge 2 is provided with standing seams.
Als Scharnier kann in bekannter Weise ein Klavierband benutzt werden, es kann ein Kunststoffprofil sein oder auch nur aus einem leicht biegbarem Blechstreifen bestehen. An den Schmalseiten der Blechtafeln 1 sind die Kanalverbindungswinkel h befestigt. Auf getrennte Winkel kann verzichtet werden, wenn die Blechtafeln in gleicher oder ähnlicher Form abgekantet werden.A piano hinge can be used as a hinge in a known manner, it can be a plastic profile or it can only consist of an easily bendable sheet metal strip. The duct connection angles h are attached to the narrow sides of the metal sheets 1. Separate angles can be dispensed with if the metal sheets are folded in the same or a similar shape.
Die Fixierungs stücke 3 sind so ausgebildet, dass sie auf der Baustelle leicht über die Stehfalze gestülpt und gegen die Kanalverbindungswinkel geschoben werden können. Mit einem Lappen fixieren sie den Kanal in aufgeklapptem Zustand. Dieser Lappen ist gleichzeitig gelocht. Durch dieses Loch wird die Verbindungsschraube zum nächsten Kanal geführt. Beim Zusammenziehen der Verbindungsschraube wird gleichzeitig diese Kraft über den 2. Lappen auf die Kanalverbindungswinkel h übertragen.The fixation pieces 3 are designed so that they can be easily slipped over the standing seams on the construction site and pushed against the duct connection angle. Use a cloth to fix the canal in the open position. This flap is perforated at the same time. The connecting screw is led through this hole to the next channel. When the connecting screw is tightened, this force is simultaneously transferred to the duct connecting angle h via the 2nd lobe.
