Description

Fahrbarer, elektrisch betriebener Sauger Bei fahrbaren, elektrisch betriebenen Saugern, die vorzugsweise in gewerblichen Betrieben, insbesondere in Textilbetrieben zum Sammeln faseriger Textilstoffe Verwendung finden sollen, muß die Befestigung des Füllsackes in solcher Weise erfolgen, daß er an seiner Befestigungsstelle möglichst wenig Staub durchläßt. Außerdem muß ein sicherer Schutz des Füllsackes vor dem Abgleiten erzielt werden. Dies ist besonders dann von Bedeutung, wenn der Füllsack an dem trichterartig erweiterten Ende der Luftleitung des Saugers befestigt wird, wobei der Sack über die trichterartige Erweiterung gezogen und an seinem oberen Ende eingeschnürt wird, so daß er sich infolge seines Gewichtes und des Druckes der einströmenden Luft dicht gegen den Trichter legt. An sich sind trichterförmig erweiterte Mundstücke der Druckleitung von Säugern bekannt. Um solche Mundstücke für fahrbare, elektrisch betriebene Sauger verwendbar zu machen, wird die Abdichtung des Sackes am Mundstück gemäß der Erfindung noch dadurch wesentlich verbessert, daß die Oberfläche des Trichters mit einem Stoffbelag versehen wird. Besonders gut eignet sich Filz hierzu. Außerdem wird infolge der durch den .Stoffbelag vergrößerten Reibung zwischen dem Sack und seiner Auflagefläche ein sicherer Schutz des Sackes vor dem Abgleiten erzielt, da die einzelnen- Gewebefasern des Stoffbelages und des Sackes eng ineinandergreifen und infolgedessen den festen Halt des Sackes erheblich verbessern.Mobile, electrically operated vacuum cleaner With mobile, electrically operated operated vacuum cleaners, which are preferably used in commercial operations, especially in Textile companies to collect fibrous textiles should be used the attachment of the filling sack takes place in such a way that it is at its attachment point lets through as little dust as possible. In addition, there must be reliable protection of the filling sack can be achieved before sliding. This is particularly important when the Filling bag attached to the funnel-like widened end of the air line of the suction cup is, with the sack pulled over the funnel-like extension and at its upper End is constricted, so that it is due to its weight and pressure the inflowing air tightly against the funnel. In themselves are funnel-shaped extended mouthpieces of the pressure line of mammals known. To mouthpieces like that To make it usable for mobile, electrically operated suction cups, the seal the sack on the mouthpiece according to the invention is still significantly improved by that the surface of the funnel is provided with a fabric covering. Particularly good felt is suitable for this. In addition, as a result of the .Stoffbelag enlarged Friction between the sack and its support surface provides reliable protection for the sack achieved before sliding because the individual fabric fibers of the fabric and the Sack tightly interlocking and consequently the firm hold of the sack considerably to enhance.

In der Abbildung ist ein Ausführungsbeispiel der Erfindung dargestellt. Der fahrbare, elektrisch betriebene Sauger ist mit einem Saugmundstück i versehen, durch das das aufzusaugende Gut über einen Ventilator i i in die Druckleitung :2 gelangt, die ein trichterartiges Mundstück 3 besitzt. - Dieses Mundstück ist bis auf den Durchmesser des Füllsackes ¢ erweitert und an seiner Oberfläche mit einem Filzbelag io versehen. Der Füllsack 4. wird durch eine Platte 5 gehalten. 9 ist eine Verschlußklappe, an deren Stelle gegebenenfalls für das Mundstück i eine bewegliche Saugleitung angeschlossen werden kann.In the figure, an embodiment of the invention is shown. The mobile, electrically operated vacuum cleaner is provided with a suction nozzle i, through the material to be sucked up into the pressure line via a fan i i: 2 which has a funnel-like mouthpiece 3. - This mouthpiece is up to the diameter of the filling sack ¢ and on its surface with a Felt covering is provided. The filling bag 4 is held by a plate 5. 9 is a closure flap, in its place optionally a movable one for the mouthpiece i Suction line can be connected.
