Description

Die Erfindung betrifft einen Fadensammler eines Saugers oder einer Saugbürste von Vorrichtungen zur Reinigung von Teppichen, textilen Belägen, Polsterungen und anderen Verkleidungsflächen aus faserartigen Stoffen, welcher Fadensammler eine flache, vorzugsweise metallische Platte besitzt, die mit einem elastischen Teil verbunden ist, dessen Arbeitsfläche mindestens einige parallele Kämme mit hochelastischen Zähnen aufweist.The invention relates to a thread collector of a vacuum cleaner or a suction brush for devices for cleaning carpets, textile coverings, upholstery and other cladding surfaces made of fibrous materials, which thread collector has a flat, preferably metallic plate, which is connected to an elastic part, the working surface of which is at least some parallel combs with highly elastic teeth.

Bei einem bekannten Fadensammler dieser Art ist beiderseits seiner Saugöffnung jeweils eine solche metallische starre Platte vorgesehen. Jede dieser Platten trägt einen elastischen, aus Kautschuk od. dgl. bestehenden kammförmigen Teil, dessen Zähne senkrecht von der Arbeitsfläche in Richtung der Saugöffnung ausgerichtet sind (GB-A-334 944).In a known thread collector of this type, such a metallic rigid plate is provided on both sides of its suction opening. Each of these plates carries an elastic, comb-like part made of rubber or the like, the teeth of which are oriented perpendicularly from the working surface in the direction of the suction opening (GB-A-334 944).

Ferner ist ein Fadensammler mit schräg in Richtung der Saugöffnung des Saugers geneigten Zähnen bekannt (US-A-3 744 082).A thread collector with teeth inclined obliquely in the direction of the suction opening of the suction device is also known (US Pat. No. 3,744,082).

Die vorerwähnten Fadensammler haben jedoch den Nachteil, daß bei der Reinigung der Teppiche, Beläge, Polsterungen oder anderen Verkleidungsflächen der Staub in die Saugbürste bzw. zwischen die Zähne eindringt und sich dort festsetzt, was dazu führt, daß der Sammler häufig gereinigt werden muß.The above-mentioned thread collectors have the disadvantage, however, that when cleaning the carpets, coverings, upholstery or other cladding surfaces, the dust penetrates into the suction brush or between the teeth and settles there, which means that the collector must be cleaned frequently.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Fadensammler der eingangs genannten Gattung zu schaffen, bei welchem dieser Nachteil eines häufigen Reinigens vermieden ist. Zu diesem Zweck ist bei dem Fadensammler der eingangs genannten Gattung erfindungsgemäß die Platte federnd ausgebildet und in den Fadensammler eingeschmolzen, welcher aus einem Material aus thermoplastischen bzw. chemisch-härtbaren Elastomeren mit einer Härte von 60 bis 95° Sh ausgeführt ist, wobei ferner die Zähne unter einem spitzen Winkel in Richtung der Saugöffnung des Saugers geneigt sind. Vorzugsweise sollte dieser spitze Winkel 50 bis 70° betragen. Zweckmäßig weisen die elastischen Zähne die Gestalt von Nadeln mit einem Scheitelwinkel von 10 bis 12° auf. Die äußeren Arbeitsflächen des Fadensammlers besitzen mindestens einige parallele Kämme mit hochelastischen Zähnen, welche unter einem spitzen Winkel in Richtung einer Schutzkante des Fadensammlers geneigt sind, welche an seiner der Saugöffnung zugewandten Seite angeordnet sein kann. Diese Schutzkante sollte die Höhe der Zähne nicht übersteigen. Die Anordnung der Kämme ist gleichläufig oder um 1/2 bzw. 1/3 der Zahnsteigung versetzt zueinander.The invention is therefore based on the object to provide a thread collector of the type mentioned, in which this disadvantage of frequent cleaning is avoided. For this purpose, in the thread collector of the type mentioned in the invention, the plate is resilient and melted into the thread collector, which is made of a material made of thermoplastic or chemically curable elastomers with a hardness of 60 to 95 ° Sh, with the teeth are inclined at an acute angle in the direction of the suction opening of the suction device. This acute angle should preferably be 50 to 70 °. The elastic teeth expediently have the shape of needles with an apex angle of 10 to 12 °. The outer working surfaces of the thread collector have at least some parallel combs with highly elastic teeth, which are inclined at an acute angle in the direction of a protective edge of the thread collector, which can be arranged on its side facing the suction opening. This protective edge should not exceed the height of the teeth. The arrangement of the combs is the same or offset by 1/2 or 1/3 of the tooth pitch.

Die vorragende Schutzkante dient zum richtigen Einsatz des Fadensammlers in die Saugplatte der Reinigungsvorrichtung.The protruding protective edge serves for the correct use of the thread collector in the suction plate of the cleaning device.

Die erfindungsgemäße Ausbildung des Fadensammlers und dabei insbesondere die Anordnung der Zähne unter einem spitzen Winkel in Richtung der Saugöffnung des Saugers, also in Richtung von dessen Arbeitsbewegung, gewährleistet ein wirksames Aufsammeln von Fäden und Haaren, wenn der Fadensammler in Richtung der Zahnneigung bewegt wird, sowie eine Selbstreinigung bei seiner Rückbewegung. Diese vorteilhafte Wirkung wird noch durch die bevorzugte Ausbildung der Zähne in Gestalt von Nadeln mit einem Scheitelwinkel von 10 bis 12° verstärkt.The inventive design of the thread collector, and in particular the arrangement of the teeth at an acute angle in the direction of the suction opening of the suction device, i.e. in the direction of its working movement, ensures effective collection of threads and hair when the thread collector is moved in the direction of the tooth inclination, and self-cleaning when moving back. This advantageous effect is further enhanced by the preferred design of the teeth in the form of needles with an apex angle of 10 to 12 °.

Der Erfindungsgegenstand wird nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Dabei zeigen :

  • Figur 1 eine Schrägansicht des auf der Gleitfläche des Saugers angeordneten Fadensammlers,
  • Figur 2 einen Querschnitt durch den Sammler,
  • Figur 3 die Draufsicht des Fadensammlers,
  • Figur 4 die Vorderansicht des Fadensammlers mit Längs-Teilschnitt, und
  • Figur 5 Schemen der Nadeleinstellung.
The subject matter of the invention is explained in more detail below with reference to an embodiment shown in the drawing. Show:
  • FIG. 1 shows an oblique view of the thread collector arranged on the sliding surface of the suction device,
  • FIG. 2 shows a cross section through the collector,
  • FIG. 3 the top view of the thread collector,
  • Figure 4 is a front view of the thread collector with partial longitudinal section, and
  • Figure 5 Schemes of needle adjustment.

Wie in der Zeichnung dargestellt, besitzt der Fadensammler 2 eine flache, federnd-starre, vorzugsweise metallische Platte 1, die in den Sammler eingegossen ist, der aus einem Material aus thermoplastischen oder chemisch härtbaren Elastomeren besteht. Die äußere Arbeitsfläche des Sammlers weist mindestens einige parallele Kämme 3 mit hochelastischen Zähnen 4 auf, die unter einem spitzen Winkel α = 50 bis 70° in Richtung der Schutzkante 5 des Sammlers 2 geneigt sind. Die Anordnung der Zähne 4 zueinander kann gleichläufig oder um 1/2 oder 1/3 der Steigung der Kammzähne versetzt zueinander sein. Die Zähne 4 haben die Gestalt kegelförmiger Nadeln mit einem Scheitelwinkel β von 10° bis 12°.As shown in the drawing, the thread collector 2 has a flat, spring-rigid, preferably metallic plate 1, which is cast into the collector, which consists of a material made of thermoplastic or chemically curable elastomers. The outer working surface of the collector has at least some parallel combs 3 with highly elastic teeth 4, which are inclined at an acute angle α = 50 to 70 ° in the direction of the protective edge 5 of the collector 2. The arrangement of the teeth 4 to each other can be the same or offset by 1/2 or 1/3 of the pitch of the comb teeth. The teeth 4 have the shape of conical needles with an apex angle β of 10 ° to 12 °.

Der Fadensammler 2 besitzt an seinen Stirnenden Vorsprünge 6 und seine Ablaufkante 7 weist einen spitzen Winkel gegenüber der Stützfläche des Sammlers auf, auf welcher an einem Ende der Vorsprung 8 angeordnet ist, der die richtige Lage des Fadensammlers in den Einrastöffnungen 10 der Saugplatte 9 derart gewährleistet, bei welcher die Schutzkante 5 an der längeren Kante der Saugöffnung 11 der Saugplatte liegt.The thread collector 2 has projections 6 at its ends and its drainage edge 7 has an acute angle with respect to the support surface of the collector, on which the projection 8 is arranged at one end, which ensures the correct position of the thread collector in the snap-in openings 10 of the suction plate 9 in this way , in which the protective edge 5 lies on the longer edge of the suction opening 11 of the suction plate.

Der erfindungsgemäße Fadensammler kann an einer oder an beiden Seiten der Saugöffnung des Saugers oder der Saugbürste angeordnet werden.The thread collector according to the invention can be arranged on one or on both sides of the suction opening of the suction device or the suction brush.
