  Handrohr für Staubsauger. 



   Bei den bekannten Staubsaugern hat das zwischen Mundstück und Gehäuse des Staubsaugers oder zwischen dem Mundstück und einem an das Gehäuse angeschlossenen Schlauch vorgesehene Handrohr als solches eine nicht veränderbare Länge. Wurde, beispielsweise zum Entstauben von Vorhängen, ein längeres Rohr benötigt, so war entweder ein Auswechseln oder ein Verlängern des vorhandenen Rohres mit Hilfe eines Ansatzrohres erforderlich. Beide   Massnahmen   sind bei oftmalige Wiederholung umständ- 
 EMI1.1 
 ausgebildet. 



   In der Zeichnung sind in Fig. 1 und 2 zwei   Ausführungsformen   des ausziehbaren Handrohres schematisch dargestellt. In beiden Figuren stellt a das ausziehbare Rohr dar, an welches das   Mundstück   des Staubsaugers (nicht dargestellt) angeschlossen wird ; b ist das Handrohr, welches mit dem Saugsehlaueh verbunden wird, welches aber auch unmittelbar an das Gehäuse des Staubsaugers angeschlossen werden kann ; d ist ein innerhalb des Handrohres angeordnetes, mit diesem fest verbundenes Führungsrohr. 



  In den Ringraum zwischen Handrohr und   Führungsrohr wird   das ausziehbare Rohr   a   eingesehoben, wenn das Handrohr als Ganzes verkürzt werden soll. Zwischen dem Führungsrohr und dem ausziehbaren Rohr sind (Fig. 2) Dichtungsmuffen angeordnet, die vorteilhaft auch ein Festhalten des Rohres a in der gewünschten Stellung ermöglichen. 



   PATENT-ANSPRUCHE :
1. Handrohr für Staubsauger, dadurch gekennzeichnet, dass es ausziehbar ausgebildet ist.

  Hand tube for vacuum cleaner.



   In the known vacuum cleaners, the hand tube provided between the mouthpiece and the housing of the vacuum cleaner or between the mouthpiece and a hose connected to the housing has as such a length that cannot be changed. If a longer pipe was required, for example to remove dust from curtains, either an exchange or an extension of the existing pipe with the help of an extension pipe was necessary. Both measures are cumbersome if they are repeated

 educated.



   In the drawing, two embodiments of the extendable hand tube are shown schematically in FIGS. 1 and 2. In both figures, a represents the pull-out tube to which the mouthpiece of the vacuum cleaner (not shown) is connected; b is the hand tube which is connected to the suction tube, but which can also be connected directly to the housing of the vacuum cleaner; d is a guide tube which is arranged inside the hand tube and firmly connected to it.



  The extendable tube a is lifted into the annular space between the hand tube and the guide tube when the hand tube as a whole is to be shortened. Sealing sleeves are arranged between the guide tube and the extendable tube (FIG. 2), which advantageously also enable the tube a to be held in the desired position.



   PATENT CLAIMS:
1. Hand tube for vacuum cleaner, characterized in that it is designed to be extendable.
