Description
Saugmundstück für StaubsaugerSuction mouthpiece for vacuum cleaners
Bei den bekannten Vorrichtungen an Staubsaugern, wie Bürsten, sich drehenden Bürsten und Filz, verfangen und verfilzen sich an den Borsten bzw. den Haaren des Filzes Fremdkörper, wie Fusseln, Fädchen usw., und werden deshalb dem Saugluftstrom nicht zur Aufsaugung freigegeben.In the known devices on vacuum cleaners, such as brushes, rotating brushes and felt, foreign bodies get caught and matted on the bristles or the hair of the felt, such as lint, threads, etc., and are therefore not released for suction by the suction air flow.
Aus dieser Erkenntnis heraus wird gemäß der Erfindung alsi Werkstoff für diese Auflockerungsvorrichtung grundsätzlich: ein Stoff verwendet, der sich mit den zu lockernden und in den Saugluftstrom zu befördernden Fusseln, Fädchen usw. nicht verfilzen kann, diese also lediglich freilegt und nicht wie die bisher vorgeschlagenen Vorrichtungen an anderer Stelle wieder festlegt, wie z. B. bei den bekannten aus Filz oder Borsten bestehenden Auflockerungsvorrichtungen. Als für die Zwecke der Erfindung besonders geeigneterOn the basis of this knowledge, according to the invention, as a material for this loosening device basically: a substance used that deals with the loosened and lint, threads, etc. that are to be conveyed in the suction air stream cannot become matted, these thus only exposed and not like the previously proposed devices on others Place again specifies, such as B. in the known made of felt or bristles Loosening devices. As particularly suitable for the purposes of the invention
ao Stoff hat sich Schwammgummi oder Schaumgummi erwiesen. Dieser hat eine die Auflockerung verbürgende rauhe Oberfläche, aber nicht die Fähigkeit, sich mit feinen Fasern o. dgl. zu verfilzen. Diese werden viel-ao fabric has been shown to be sponge rubber or foam rubber. This one has a loosening up Guaranteed rough surface, but not the ability to deal with fine fibers to felt or the like. These are often
«5 mehr von ihrer Unterlage freigemacht, an dem Lockerungsmittel selbst aber nicht verankert und können deshalb, wenn sie in den Bereich des Saugstromes kommen, von diesem behinderungslos abgesaugt werden. Der Auflockerungsschwammgummi kann auf jede geeignete Weise fest oder beweglich an den Staubsaugern, insbesondere den Saugmundstücken, angebracht werden. Es empfiehlt sich im allgemeinen die bewegliche Anordnung, insbesondere in Form eines in sich geschlossenen Zubehörteiles, das man den vorhandenen Saugmundstüeken anpassen kann. Die in der Zeichnung dargestellte Ausführungsform zeigt Haltestege β mit Versteifungen b und erne dazwischen drehbar angebrachte SchNrarnmgummirolle c auf einem Saugmundstück d aufgebracht, so daß die Schwamrngummirolle die von ihr ergriffenen Fremdkörper durch Herumwenden dem freien Saugluftstrom zur Aufsaugung zurollen kann.«5 more of their base, but not anchored to the loosening agent itself and can therefore, if they come into the area of the suction flow, be sucked off by it without hindrance. The loosening sponge rubber can be attached fixedly or movably to the vacuum cleaners, in particular the suction mouthpieces, in any suitable manner. It is generally advisable to use the movable arrangement, in particular in the form of a self-contained accessory that can be adapted to the existing suction mouthpieces. The embodiment shown in the drawing shows retaining webs β with stiffeners b and erne hinged rubber roller c mounted rotatably between them applied to a suction mouthpiece d so that the sponge rubber roller can roll the foreign bodies it has gripped by turning around the free suction air flow for suction.
