Description
Die Erfindung betrifft eine Getriebevorrichtung zur Betreibung einer rotierenden Bürste mittels eines handgetriebenen Arbeitsgeräts mit lanzenförmiger Verbindungswelle.The invention relates to a transmission device for operating a rotating brush by means of a hand-driven tool with a lance-shaped connecting shaft.
Bodenreinigungsmaschinen mit um eine senkrechte Achse rotierenden Reinigungsbürsten sind beispielsweise aus
Leichtere, handgetriebenen Bodenreinigungsgeräte, welche von einem Nutzer getragen werden können, sind ebenfalls bekannt. So gibt es ein handgetriebenes Bodenreinigungsgeräte in der Form eines Rucksacks mit einer sogenannten Dampflanze. Dabei wird heisser Dampf unter Druck auf die Kaugummireste geleitet. In einer Varianten kann die Dampflanze am freien Ende eine Bürste aufweisen, mit welcher zum Beispiel durch den heissen Dampf aufgeweichte Kaugummireste durch zusätzliches hin- und herbewegen der Bürste weggebürstet werden. Die Reinigungsfunktion basiert im Wesentlichen auf dem heissen Dampf und allenfalls den zugesetzten Reinigungsmitteln. Um die Kaugummireste wegzubürsten ist allerdings ein erheblicher Kraftaufwand notwendig.Lighter, hand-operated floor cleaning devices that can be carried by a user are also known. For example, there is a hand-operated floor cleaning device in the form of a backpack with a so-called steam lance. Hot steam is directed under pressure onto the chewing gum residue. In one variant, the steam lance can have a brush at the free end, with which, for example, chewing gum residue softened by the hot steam can be brushed away by additionally moving the brush back and forth. The cleaning function is essentially based on the hot steam and possibly the added cleaning agents. However, considerable effort is required to brush away the chewing gum residue.
Es ist auch eine Bürstenkopf bekannt, welcher an der Lanze einer herkömmlichen Motorsense oder eines Freischneiders befestigt werden kann und insbesondere zur Unkrautentfernung verwendet. Mit den sehr schnell rotierenden Bürsten wird trocken und kalt gebürstet. Kaugummireste können mit einem solchen Handgerät nur bedingt entfernt werden.There is also a brush head that can be attached to the lance of a conventional brush cutter or brushcutter and is used in particular for removing weeds. The very fast rotating brushes are used for dry and cold brushing. Chewing gum residue can only be removed to a limited extent with such a hand-held device.
Es besteht daher ein Bedarf nach einem leichten Bodenreinigungsgerät, mittels welchem Kaugummireste effizient beseitigt werden können.There is therefore a need for a lightweight floor cleaning device that can efficiently remove chewing gum residue.
