F i g. 5 eine Ansicht gemäß der Linie V-V in F i g. 4; undF i g. 5 is a view according to the line V-V in FIG. 4; and

F i g. 6 eine wiederum den F i g. 2 und 4 entsprechende Darstellung der Vorrichtung mit Absaughaube und Luftleitung sowie Wandanschluß, jedoch unter Weglassung der Längsführungen und Zugorgane.F i g. 6 one in turn the FIG. 2 and 4 corresponding representation of the device with suction hood and Air duct and wall connection, but omitting the longitudinal guides and pulling elements.

Das in F i g. 1 perspektivisch dargestellte Dunstabzugsgehäuse besteht aus dem Schachtelement 1 und der Schachtschürze 2, die im Beispiel aus Holz o. dgl. (Spanplatten o. ä.) hergestellt sind. Das Schachtelement 1 läßt sich — wie die Fig.2, 4 und 6 verdeutlichen — im Winkel zwischen der Küchendecke und einer Küchenwand befestigen. Die Schachtschürze 2 hat im Horizontalschnitt im wesentlichen U-Form und umfaßt das Schachtelement 1 in der am besten in F i g. 1 erkennbaren Weise.The in Fig. 1 extractor housing shown in perspective consists of the shaft element 1 and the Manhole apron 2, which in the example are made of wood or the like (chipboard or the like). The shaft element 1 leaves - as FIGS. 2, 4 and 6 make clear - in Fasten the angle between the kitchen ceiling and a kitchen wall. The shaft skirt 2 has a horizontal section substantially U-shape and comprises the shaft element 1 in the best shown in FIG. 1 recognizable Way.

Die Schachtschürze 2 ist gegenüber dem Schachtelement 1 mit Hilfe zweier Längsführungen 3 gehalten und vertikalverschieblich geführt, welche im Innern von Schachtelement 1 und Schachtschürze 2 angeordnet sind, und zwar im Beispiel im Bereich der beiden Seitenwände. Die F i g. 2 und 3 zeigen eines der beiden Längsführungselemente 3, welches einerseits (oben) am Schachtelement 1, andererseits (unten), und zwar unter Zwischenschaltung eines Klotzes 3a, an der Schachtschürze befestigt ist. In einer einfachen Form können die Längsführungselemente 3 aus Teleskop-Schubkastenführungen bestehen, jedoch sind ihrer größeren Präzision wegen Längskugelführungen vorzuziehen.The shaft skirt 2 is held relative to the shaft element 1 with the aid of two longitudinal guides 3 and guided vertically displaceably, which are arranged inside the shaft element 1 and shaft skirt 2 are, in the example in the area of the two side walls. The F i g. 2 and 3 show one of the two longitudinal guide elements 3, which on the one hand (above) on the shaft element 1, on the other hand (below), namely below Interposition of a block 3a to which the shaft skirt is attached. In a simple form you can the longitudinal guide elements 3 consist of telescopic drawer guides, but their larger ones Precision to be preferred because of longitudinal ball guides.

Ebenfalls im Bereich der Seitenwände sind — wie die F i g. 4 und 5 veranschaulichen — Zugorgane in Form hochfester Textilbänder oder nichtrostender Stahlbänder vorgesehen, welche einerseits auf Wickeltrommeln 5 aufwickelbar sind, die im oberen Bereich des Schachtelements 1 befestigt sind. Andererseits sind die Zugorgane 6 mittels Halterungen 9 an der Schachtschürze 2 befestigt.Also in the area of the side walls are - as FIG. Figures 4 and 5 illustrate traction members in shape High-strength textile tapes or stainless steel tapes are provided, which on the one hand on winding drums 5 which are fastened in the upper region of the shaft element 1 can be wound up. On the other hand are the traction organs 6 attached to the shaft skirt 2 by means of brackets 9.

Die beiden Wickeltrommeln 5 für das Zugorgan 6 sind durch eine Antriebswelle 8 miteinander verbunden, in die ein Antriebsmotor 4 eingeschaltet ist, welcher — wie oben dargelegt — ein Getriebe und weitere Schaltelemente enthält. Der Motor 4 und die Wickeltrommeln 5 sind dabei auf einer gemeinsamen Konsole 7 angeordnet, weiche sich quer durch das Schachtelement 1 erstreckt (F ig. 5).The two winding drums 5 for the pulling element 6 are connected to one another by a drive shaft 8, in which a drive motor 4 is switched on, which - as explained above - a transmission and further switching elements contains. The motor 4 and the winding drums 5 are arranged on a common bracket 7, soft extends transversely through the shaft element 1 (Fig. 5).

F i g. 6 schließlich zeigt unter Weglassung der Längsführungselemente 3 und der Zugorgane 6 etc. die Anordnung der Absaugvorrichtung 11 in der Schachtschürze 2 und die teleskopartige Ausbildung der Luftleitung 10, welche mit ihrem oberen Krümmer in den Wandanschluß 12 eines nicht weiter dargestellten Abluftkanals mündet Statt der zweiteiligen teleskopartigen Luftleitung 10 kann auch eine einteilige Luftleitung in Form eines Faltenbalgschlauches o. dgl. vorgesehen sein.F i g. 6 finally shows omitting the longitudinal guide elements 3 and the pulling elements 6 etc. the arrangement of the suction device 11 in the shaft skirt 2 and the telescopic design of the air line 10, which with its upper bend in the Wall connection 12 of a not shown exhaust duct opens out instead of the two-part telescopic Air line 10 can also be a one-piece air line in the form of a bellows tube or the like be.
