und mit wenigstens einer weiteren Seiltrommel (18', 18'', 20', 20'')
mit einem Gegengewicht (32) verbunden sind, dadurch gekennzeichnet,
dass
– das
Zugseil (16; 16') jeder Seite auf einer eigenen Zugseiltrommel (18,
18a; 20, 20a) schlupffrei aufgewickelt ist,
– jede Zugseiltrommel
(18, 18a; 20, 20a) oberhalb der jeweiligen seitlichen Führungsschiene
(10; 12) in einem Gestell (19; 21) auf je einer Welle (24; 26) befestigt
ist,
– auf
jeder Welle (24; 26) wenigstens eine weitere Seiltrommel (18', 18'';
20', 20'') für
wenigstens ein mit dem Gegengewicht (32) verbundenes Gegengewichtsseil
(30; 30') gelagert ist,
– die
Seiltrommeln (18, 18a, 18', 18''; 20, 20a, 20',...Fume hood with a working space which is closed on all sides and which has on the front side a sash (14) guided in a lateral guide rail (10, 12), which is suspended laterally from tension cables (16, 16 ') which are associated with at least one side of the guide Tensioning drum (18, 18a, 20, 20a) out and at least one further cable drum (18 ', 18'',20', 20 '') are connected to a counterweight (32), characterized in that

Die
Die Aufgabe der vorliegenden Erfindung besteht darin, einen Laborabzug der eingangs genannten Art anzugeben, dessen Frontschieber sicherer und einfacher handhabbar und in einer kompakteren Bauweise aufgehängt ist.The The object of the present invention is a fume hood specify the type mentioned, the sash and safer easier to handle and suspended in a more compact design.
Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst.These The object is achieved by the invention according to claim 1.
Vorteilhafte und zweckmäßige Weiterbildung der Aufgabenlösung sind in den Unteransprüchen angegeben.advantageous and appropriate training of task solution are given in the subclaims.
Die Erfindung soll nachfolgend anhand der beigefügten Zeichnung, in der ein Ausführungsbeispiel dargestellt ist, näher erläutert werden.The Invention will be described below with reference to the accompanying drawings in which embodiment is shown, closer explained become.

zur Erfassung der Anwesenheit von Nutzern des Laborabzugs
Über das erfindungsgemäße Welle/Trommel-System können verschiedene Funktionen und Eingriffsmöglichkeiten realisiert werden, da die Welle, aber auch die Trommel, eine Art maschinenbauliche Schnittstelle für weitere Aggregate darstellt. So können außer der erwähnten Sensorik ein Bypass oder eine Klappe für eine Regelung leicht mechanisch angeschlossen werden. Nicht lineare Kräfte (z. B. aus Federsystemen) können durch Kurvenscheiben oder konische Trommeln mit linearen Momenten auf die Welle wirken.About the shaft / drum system according to the invention can different functions and intervention possibilities can be realized because the wave, but also the drum, a kind of mechanical engineering Interface for represents further aggregates. Thus, in addition to the aforementioned sensors, a bypass or a flap for a scheme can be easily connected mechanically. Nonlinear personnel (eg from spring systems) through cams or conical drums with linear moments the wave is working.
