Description

Die Erfindung bezieht sich auf einen Staubsauger mit von Hand anzutreibender, doppelt wirkender Kolbenpumpe und bezweckt Verbesserungen zur Erleichterung der Handhabung eines solchen Staubsaugers.The invention relates to a vacuum cleaner with a hand-operated double acting piston pump and aims to improve the handling such a vacuum cleaner.

Der bei den bekannten Staubsaugern dieser Art gebräuchliche Antrieb für die Kolbenpumpe besteht aus zwei in einer Längsmittelebene der Pumpe gegeneinander beweglichen Handhebeln und aus zwei diese Handhebel mit der Kolbenstange verbindenden Lenkern. Hierbei ist ein großer Ausschlag der Handhebel nötig, um den Pumpenkolben von der einen in die andere Endstellung zu verschie-The common drive for the piston pump in known vacuum cleaners of this type consists of two hand levers that can be moved against each other in a longitudinal center plane of the pump and two of these hand levers connecting rods with the piston rod. The hand lever is a big deflection here necessary to move the pump piston from one end position to the other.

,15 ben. Da mittels der Handhebel gleichzeitig der Staubsauger auf der zu reinigenden Fläche hin und her geschoben werden muß, sind die weiten Handhebelausschläge der ordnungsmäßigen Bedienung des Staubsaugers hinderlieh, und zwar besonders wenn die Pumpe doppelt wirkend ist. Die Erfindung beseitigt diesen Nachteil dadurch, daß zwischen den Handhebeln ^nd der Kolbenstange eine mehrfache Hebelschere eingeschaltet ist. Der Handhebelausschlag wird dabei auf einen Bruchteil des ~ bisher erforderlichen Maßes verringert, wodurch die Bedienung des Staubsaugers» in erheblichem Maße gefördert ist. Ein Ausführungsbeispiel ist in einer Ansichtsdarstellung erläutert., 15 ben. Because the hand lever simultaneously places the vacuum cleaner on the surface to be cleaned has to be pushed back and forth, the wide hand lever deflections are the proper ones Operation of the vacuum cleaner is an obstacle, especially when the pump is double acting. The invention eliminates this disadvantage in that between the Hand levers ^ nd the piston rod a multiple lever cutter is switched on. Of the Hand lever deflection is reduced to a fraction of the previously required amount reduced, whereby the operation of the vacuum cleaner »is promoted to a considerable extent. One embodiment is in a view representation explained.

Im Staubsaugergehäuse 4 ist ein doppelt wirkender Kolben 1 mit einer Kolbenstange 2 angeordnet. Auf dem oberen Deckel des Staubsaugergehäuses 4 sind die beiden Handhebel 3° und 2>b gelenkig gelagert. Zwischen diesen Handhebeln und dem oberen Ende der Kolbenstange ist eine mehrfache Hebelschere eingeschaltet, die von den Gelenkpunkten 5, S der beiden Handhebel mit den doppelarmigen Hebern 6 und 7 ausgeht, die in dem Gelenkpunkt 8 einander kreuzen, und an deren Enden mit dem Drehzapfen 9, 9 die beiden Lenker ι ο und 11 angeschlossen sind, die mittels der Gelenkzapfen 12, 12 die Kolbenstange führen. Die doppelarmigen Hehei 6 und 7 sowie die Lenker 10 und 11 sind so gekrümmt, daß sie die Neigung haben, sich parallel zu den Handhebeln y un(i 3b em" zustellen.A double-acting piston 1 with a piston rod 2 is arranged in the vacuum cleaner housing 4. The two hand levers 3 ° and 2> b are articulated on the upper cover of the vacuum cleaner housing 4. Between these hand levers and the upper end of the piston rod, multiple lever scissors are connected, which start from the hinge points 5, S of the two hand levers with the double-armed lifters 6 and 7, which cross each other at the hinge point 8, and at their ends with the pivot 9 , 9 the two links ι ο and 11 are connected, which guide the piston rod by means of the pivot pin 12, 12. The double-armed hehei 6 and 7 as well as the handlebars 10 and 11 are curved so that they tend to be parallel to the hand levers y un ( i 3 b em ".

Mittels der mehrfachen Hebelschere 6, 7, 10, Ii ist der zur Ausführung des vollen Kolbenhubes erforderliche Handhebelausschlag so stark vermindert, daß er leicht von jeder den Staubsauger bedienenden Person ausgeführt werden kann. Damit ist auch die Sicherheit geschaffen, daß der Kolbenhub immer vollständig ausgenutzt wird.The multiple lever scissors 6, 7, 10, Ii are used to execute the full piston stroke required hand lever deflection is reduced so much that it can easily be removed from each of the Vacuum cleaner operating person can be executed. So with that is security created that the piston stroke is always fully used.
