Description

Staubsauger. Die Erfindung betrifft einen Staubsauger derjenigen Art, bei welcher eine in. der SaugcNise gelagerte, sich drehende Bürste von dem Motor angetrieben wird. Das Wesen der Erfindung besteht der Hauptsache nach darin, (Maß auf der starren Bürstenwelle eine Gleit-()der Reibungskupplung angeordnet ist, die beim Verfangen der Bürste oder bei ihrer Verhinderung an ihrer Drehung ein Schlüpfen zwischen der Bürste und der 'Motorwelle ermöglicht. Auf diese Weise werden unzulässige Beanspruchungen oder Beschädigungen des Geräts verhütet.Vacuum cleaner. The invention relates to a vacuum cleaner of the type in which a rotating brush mounted in the suction device from the motor is driven. The essence of the invention consists mainly in (measure A sliding () friction clutch is arranged on the rigid brush shaft, which slipping when the brush is caught or prevented from rotating between the brush and the 'motor shaft. This way it will be inadmissible Avoid using or damaging the device.

Auf der Zeichnung ist die Erfindung in einer Ausführungsform beispielsweise dargestellt; es sind: -'ebb. i senkrechter Längsschnitt durch den Staubsauger, wobei der Übersichtlichkeit halber einige Teile weggelassen sind, Abb. 2 Vorderansicht mit zum Teil fortgeschnittener Bürstenkammer (Bürstenkopf), Abb. 3 Sonderdarstellung des Antriebs mit nachgiebiger Kupplung.In the drawing, the invention is in one embodiment, for example shown; they are: -'ebb. i vertical longitudinal section through the vacuum cleaner, where some parts have been omitted for the sake of clarity, Fig. 2 front view with partly cut away brush chamber (brush head), Fig. 3 special illustration of the drive with a flexible coupling.

In einer Kammer des auf Räder gesetzten Gehäuses A ist der Motor B angeordnet, der den Sauger C in einer hinteren Querkammer antreibt. Die Bürstenkarnmer (Bürstenkopf) D mit dem Saugmunde unterhalb der Bürste liegt quer vor dem Gehäuse und steht durch den Kanal ;1' mit dem Sauger in Verbindung.The motor B is located in a chamber of the housing A, which is placed on wheels arranged, which drives the sucker C in a rear transverse chamber. The brush box (Brush head) D with the suction mouth below the brush lies across in front of the housing and is connected to the suction device through the channel; 1 '.

Die Welle der Bürste E trägt in einem baum, der einen achsialen Fortsatz der Düse und Bürstenkammer bildet, ein Schneckenrad F im Eingriff mit einer Schnecke G, die mittels biegsamer Welle Il von dem Motor B angetrieben wird. Die Gleit- oder Reibungskupplung 1 stellt zwischen dem Rad F und der Bürstenwelle E eine solche Verbindung her, daß der Antrieb aufhört, wenn ein störender Gegenstand in die Bürstenkammer eingesaugt wird und sich mit der Bürste verfängt oder die Bürste irgendwie an der Drehung gehindert wird.The shaft of the brush E carries in a tree that has an axial extension the nozzle and brush chamber forms a worm wheel F in engagement with a worm G, which is driven by the motor B by means of a flexible shaft II. The sliding or Friction clutch 1 is between the wheel F and the brush shaft E such Connection so that the drive stops if an interfering object enters the brush chamber sucked in and caught in the brush or the brush somehow on the Rotation is prevented.

In der dargestellten Ausführungsart besteht die Kupplung aus einer auf der Bürstenwelle undrehbaren federnden Scheibe I', die gegen das Rad F anliegt, (las lose auf der Welle sitzt. Die Mutter J gestattet: die federnde Scheibe mit der gehörigen Spannung gegen das Rad F einzustellen.In the embodiment shown, the coupling consists of one on the brush shaft non-rotatable resilient washer I ', which rests against the wheel F, (Read sits loosely on the shaft. The nut J allows: the resilient washer with the appropriate tension against the wheel F to adjust.

PATENTANSPRÜCHE: t. Staubsauger, bei welchem eine sich drehende Bürste innerhalb der Saugdüse gelagert ist und von dem Motor angetrieben wird, dadurch gekennzeichnet, daß auf der starren Welle der Bürste (E) in einem einen achsialen Fortsatz der Düse und Bürstenkammer bildenden Raum eine Gleit- oder Reibungskupplung zwischen der Bürstenwelle und der Motorweile angeordnet ist, damit beint Verfangen der Bürste oder ihrer Drehungsverhinderung ein Schlüpfen zwischen der Bürste und der Motorwelle stattfinden kann. PATENT CLAIMS: t. Vacuum cleaner with a rotating brush is mounted within the suction nozzle and is driven by the motor, thereby characterized in that on the rigid shaft of the brush (E) in a one axial Extension of the nozzle and brush chamber forming space a sliding or friction clutch is arranged between the brush shaft and the motor shaft, so that legs get caught the brush or its rotation prevention, a slip between the brush and the motor shaft can take place. 2. Staubsauger nach Anspruch i, dadurch gekennzeichnet, daß sich für die nachgiebige Kupplung eine auf der Bürstenwelle undrehbare federnde Scheibe (II) gegen die eine Fläche des lose auf der Bürstenwelle sitzenden Zahnrades (G) anlegt.2. Vacuum cleaner according to claim i, characterized in that that there is a non-rotatable resilient on the brush shaft for the flexible coupling Washer (II) against one surface of the gear wheel loosely seated on the brush shaft (G) applies.
