Description

Die Erfindung geht aus von einer Einfassung für Überdach-Entlüftungsrohre oder -Abluftkamine gemäss dem Oberbegriff des Patentanspruches, welcher aus der GB-A-1 080 837 bekannt ist.The invention relates to an enclosure for roof ventilation pipes or exhaust chimneys according to the preamble of the claim, which is known from GB-A-1 080 837.

Damit ein Überdach-Entlüftungsrohr oder Abluftkamin stets in einer senkrechten Position auf einem Schrägdach bleibt, wurden verschiedene Einfassungen verwendet. So sind z. B. Kugeln oder Kappen bekannt, die an die Dachneigung gelegt werden, wobei die Manschetten an den Kugeln oder Kappen vernietet und die Manschette selbst am Rohr oder Kamin verklebt wird. In der europäischen Patentanmeldung 0 131 086 ist ein Dachentlüftungsrohr beschrieben, dessen oberhalb der Dachpfanne liegender Abschnitt durch eine Kappe gebildet ist. Letztere überfängt eine über die Oberseite der Dachpfanne vorstehende Kuppel, wobei beide Teile formangepasst sind. Auf diese Weise kann das Entlüftungsrohr in der Durchtrittsöffnung, die eine grosse Länge aufweist, der Dachneigung in einem Bereich von ca. 20 - 35° angepasst werden.Various edging was used to ensure that a roof ventilation pipe or exhaust chimney always remains in a vertical position on a sloping roof. So z. B. balls or caps are known, which are placed on the roof pitch, the sleeves riveted to the balls or caps and the sleeve itself is glued to the pipe or chimney. In European patent application 0 131 086 a roof ventilation pipe is described, the portion above the roof tile is formed by a cap. The latter covers a dome protruding over the top of the roof tile, both parts being adapted to the shape. In this way, the ventilation pipe in the passage opening, which has a large length, can be adapted to the roof pitch in a range of approximately 20-35 °.

Bei den meisten bekannten Einfassungen dieser Art müssen aber immer nach der Montage Anpassungsarbeiten ausgeführt werden, damit das Rohr bzw. der Kamin immer senkrecht bleibt. Des weiteren ist die Anpassungsmöglichkeit des Rohres bzw. des Kamins an die Dachneigung stark beschränkt.In most known surrounds of this type, however, adjustment work must always be carried out after assembly so that the pipe or chimney always remains vertical. Furthermore, the possibility of adapting the pipe or the chimney to the roof pitch is very limited.

Aus der GB-A-1 080 837 ist eine aus elastischem Material bestehende Einfassung für Überdach-Entlüftungs rohre oder -Abluftkamine beschrieben, die zur Anpassung an die Dachschräge unmittelbar über dem Anschlussflansch balgartig ausgebildet ist.GB-A-1 080 837 describes an enclosure for elastic roof pipes or exhaust air chimneys which is made of elastic material and which is designed to be bellows-shaped to adapt to the roof slope directly above the connection flange.

Es ist nun Aufgabe der vorliegenden Erfindung, eine verbesserte Einfassung für Überdach-Entlüftungsrohre oder -Abluftkamine aus flexiblem Material zur Verfügung zu stellen, die für Dachschrägen von 15 - 60° geeignet ist.It is an object of the present invention to provide an improved enclosure for roof vent pipes or exhaust chimneys made of flexible material, which is suitable for roof slopes of 15-60 °.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teiles des Patentanspruches gelöst. Bei der Einfassung für Überdach-Entlüftungsrohre oder -Abluftkamine müssen nach der ausgeführten Montage keine Anpassarbeiten mehr verlangt werden. Bei einer solchen Einfassung ist kein Abdichten mit Spachtelmassen usw., kein Verschrauben, Vernieten oder Kleben von Einzelteilen erforderlich.This object is achieved according to the invention by the features of the characterizing part of the patent claim. With the edging for roof ventilation pipes or exhaust chimneys, no adjustment work is required after the installation has been carried out. With such a border, no sealing with fillers, etc., no screwing, riveting or gluing of individual parts is required.

Der Erfindungsgegenstand wird nachstehend anhand der Zeichnung beispielsweise näher erläutert. Es zeigen:

  • Fig. 1 eine Seitenansicht im Schnitt einer auf einem Schrägdach verlegten Einfassung mit einer auf dem Entlüftungsrohr aufgezogenen Manschette aus einem biegsamen Material,
  • Fig. 2 einen Teilschnitt im grösseren Maßstab der Manschette nach der Figur 1 mit einem eingelegten Stahlring,
  • Fig. 3 einen Teilschnitt im grösseren Maßstab der Manschette nach der Figur 1 mit einem eingelegten Stahlring und einer gebildeten Materialfalte,
The subject matter of the invention is explained in more detail below with reference to the drawing, for example. Show it:
  • 1 is a side view in section of a bezel installed on a pitched roof with a sleeve made of a flexible material that is fitted onto the ventilation pipe,
  • 2 shows a partial section on a larger scale of the sleeve according to FIG. 1 with an inserted steel ring,
  • 3 shows a partial section on a larger scale of the sleeve according to FIG. 1 with an inserted steel ring and a material fold,

In den Figuren 1 bis 3 ist eine erste Ausführungsform der erfindungsgemässen Einfassung für Überdach-Entlüftungsrohre oder -Abluftkamine dargestellt.FIGS. 1 to 3 show a first embodiment of the enclosure according to the invention for roof ventilation pipes or exhaust air chimneys.

Die Einfassung umfasst einen flexiblen, an das Schrägdach 12 verlegbaren Anschlussflansch 1 mit einer Öffnung für das Entlüftungsrohr 10 bzw. den Abluftkamin. Mit dem Anschlussflansch 1 ist eine Manschette 2 aus einem biegsamen Material verbunden. Im Querschnitt entspricht der Innendurchmesser der Manschette 2 etwa dem Aussendurchmesser des Rohres 10 bzw. des Kamins. Die Manschette 2 besteht z. B. aus Leder oder Kunststoff ("PVC"). Die Manschette 2 ist auf das Rohr 10 bzw. den Kamin aufziehbar.The enclosure comprises a flexible connection flange 1 that can be laid on the sloping roof 12 and has an opening for the ventilation pipe 10 or the exhaust air chimney. A sleeve 2 made of a flexible material is connected to the connecting flange 1. In cross section, the inside diameter of the sleeve 2 corresponds approximately to the outside diameter of the pipe 10 or the chimney. The cuff 2 is z. B. made of leather or plastic ("PVC"). The cuff 2 can be pulled onto the pipe 10 or the chimney.

Der dem Dachfirst 13 zuzukehrende Wandabschnitt der Manschette 2 ist in seiner Höhe kürzer ausgebildet als der ihm gegenüberliegende Wandabschnitt. Das heisst, dass die durch den frei liegenden Rand 3 der Manschette 2 geführte Ebene mit der Ebene des Anschlussflansches 1, der auf dem Schrägdach 12 zum Anliegen kommt, einen spitzen Winkel einschliesst. Der freie Rand 3 der Manschette 2 ist mittels einer Spannbride 4 am Rohr 10 bzw. Kamin so befestigbar, dass er im befestigten Zustand der Manschette 2 senkrecht zur Längsachse 11 des Rohres 10 bzw. Kamins liegt. Der dem Dachfirst 13 zuzukehrende kürzere Wandabschnitt der Manschette 2, ist praktisch höhenunverstellbar oder starr, wogegen der dem Dachfirst 13 abzukehrende Wandabschnitt der Manschette 2 samt dem Anschlussflansch 1 von Hand höhenverstellbar ist. Dadurch wird die Anpassung an die verschiedene Neigung des Schrägdaches 12 problemlos erzielt. In der Figur 1 beträgt die Dachneigung a 45° und die Dachneigung a' 30°. Mit 14 ist ein Regenhut des Rohres 10 bzw. des Kamins bezeichnet.The wall section of the sleeve 2 facing the ridge 13 is shorter in height than the wall section opposite it. This means that the plane led through the exposed edge 3 of the sleeve 2 forms an acute angle with the plane of the connecting flange 1, which comes to rest on the sloping roof 12. The free edge 3 of the sleeve 2 can be fastened to the pipe 10 or chimney by means of a clamping bracket 4 such that it is perpendicular to the longitudinal axis 11 of the pipe 10 or chimney when the sleeve 2 is fastened. The shorter wall section of the sleeve 2 facing the ridge 13 is practically not height-adjustable or rigid, whereas the wall section of the sleeve 2 facing away from the roof ridge 13, including the connecting flange 1, is height-adjustable by hand. As a result, the adaptation to the different inclination of the sloping roof 12 is achieved without problems. In Figure 1, the roof pitch is 45 ° and the roof pitch a '30 °. With 14 a rain hat of the pipe 10 or the chimney is designated.

Annähernd in der Mitte des Abstandes des freien Randes 3 der aus einem biegsamen Material bestehenden Manschette von dem Anschlussflansch 1 ist ein Stahlring 5 eingesetzt, um welchen sich bei Höhenverstellung des dem Dachfirst 13 abzukehrenden längeren Wandabschnittes der Manschette 2 eine Materialfalte 6 bildet. Diese Materialfalte 6 ist insbesondere aus der Figur 3 gut sichtbar.Approximately in the middle of the distance of the free edge 3 of the sleeve made of a flexible material from the connecting flange 1, a steel ring 5 is inserted, around which a material fold 6 forms when the longer wall section of the sleeve 2 facing away from the ridge 13 is formed. This fold of material 6 is particularly clearly visible from FIG. 3.

Bei der Montage der Dacheinfassung werden keine speziellen Werkzeuge verwendet. Die Montage geht auf einfache Art vor sich. Die Manschette 2 mit dem Anschlussflansch 1 wird über das Belüftungsrohr 10 bzw. den Abluftkamin straffgezogen, wobei der Anschlussflansch 1 an die Dachneigung angepasst wird. Dann wird etwa 15 - 20 mm unterhalb des Manschettenrandes 3 die Spannbride 4 aufgesetzt und mit Schraubenzieher festgezogen. Die Randfuge der Manschette 2 wird mit Silikon abgedichtet. Nach der Montage werden keine weiteren Anpassarbeiten benötigt. Die Montage wird von einer Person durchgeführt.No special tools are used when installing the roof frame. The assembly is simple. The sleeve 2 with the connection flange 1 is pulled tight via the ventilation pipe 10 or the exhaust air chimney, the connection flange 1 being adapted to the roof pitch. Then the clamp 4 is placed about 15 - 20 mm below the collar edge 3 and tightened with a screwdriver. The edge joint of the sleeve 2 is sealed with silicone. No further adjustments are required after installation. The assembly is carried out by one person.

Die Einfassung eignet sich für Dachschrägen von etwa 15 bis 60°. Durch den flexiblen Teil der Einfassung werden eventuelle Massfehler oder Ungenauigkeiten automatisch kompensiert. Dabei werden die Dachabsenkung oder Wärmedehnung aufgenommen und Vibrationen absorbiert.The edging is suitable for sloping ceilings from about 15 to 60 °. The flexible part of the frame automatically compensates for any dimensional errors or inaccuracies. The roof lowering or thermal expansion are absorbed and vibrations are absorbed.
