Abstract
Description
Die Erfindung bezieht sich auf eine Staubsaugerdüse mit an der Düsenunterseite angebrachten elastischen Leisten oder Lippen.The invention relates to a vacuum cleaner nozzle elastic strips attached to the underside of the nozzle or Lips.
Es sind Staubsaugerdüsen bekannt, bei denen elastische Leisten oder Lippen aus Gummi oder weichem Kunststoff an der Düsenunterseite zum Teil oder auch über die gesamte Arbeitsbreite hinter der Saugöffnung angebracht sind. Dadurch wird der Saugstrom konzentrierter geführt und das Entstehen unwirksamer Nebenluft verhindert.Vacuum cleaner nozzles are known in which elastic Moldings or lips made of rubber or soft plastic the underside of the nozzle, in part or over the whole Working width behind the suction opening. This leads to a more concentrated suction flow and that Ineffective secondary air is prevented.
Durch ihre Elastizität weichen die Leisten bei der Vor- und Rückwärtsbewegung der Saugdüse flexibel aus, je nach Widerstand der zu säubernden Fläche z.B. bei Teppichbelägen in Abhängigkeit von der Florhöhe. Die Leisten spreizen auch den Flor und erleichtern dadurch die Säuberung aus der Tiefe des Florbesatzes. An der Oberfläche haftender Schmutz wird zum Absaugen gelockert und der Teppichflor aufgefrischt.Thanks to their elasticity, the lasts and backward movement of the suction nozzle depending on Resistance of the surface to be cleaned e.g. for carpets depending on the pile height. The strips also spread the pile and thereby facilitate cleaning from the Depth of the pile. Dirt adhering to the surface is loosened for suction and the carpet pile refreshed.
Diese Leisten weisen aber den Nachteil auf, daß abriebfeste Materialtypen für die Leisten unflexibel sind und das zulässige Maß des Schiebewiderstandes erhöhen. Bei hochelastischen Werkstoffen aus Gummi oder Kunststoff erhöht sich der Verschleiß und die Befestigung der Leisten am Düsenteil ist aufwendig, schwierig und unbefriedigend. However, these strips have the disadvantage that they are resistant to abrasion Material types for the strips are inflexible and that Increase the permissible dimension of the sliding resistance. At highly elastic materials made of rubber or plastic the wear and the fastening of the strips increases on the nozzle part is complex, difficult and unsatisfactory.
Wird die Wandstärke der Lippen an den Leisten zu dünn gewählt, um die gewünschte Flexibilität zu erreichen, werden sie vom Saugstrom zur Saugöffnung gezogen und verlieren ihre Wirksamkeit.If the wall thickness of the lips on the strips is too thin chosen to achieve the desired flexibility, they are drawn from the suction flow to the suction opening and lose their effectiveness.
Der Erfindung liegt die Aufgabe zugrunde, eine Staubsaugerdüse der genannten Art zu schaffen, deren Leisten bzw. Lippen abriebfest und zugleich flexibel sind, wobei sich der Schiebewiderstand nicht erhöht und die Anbringung am Düsenunterteil relativ einfach möglich ist.The invention has for its object a To create vacuum cleaner nozzle of the type mentioned, the Last or lips abrasion-resistant and flexible at the same time are, the sliding resistance does not increase and attachment to the lower part of the nozzle is relatively easy is.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß die Leiste aus einem Befestigungsteil und einer Lippe besteht, die über eine Sollbiegestelle miteinander verbunden sind, wobei ein Wegkippen der Lippe in Richtung der Saugöffnung über Begrenzungselemente verhinderbar ist, und das Befestigungsteil aus hartem und die Lippe aus weichem Material besteht. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Merkmalen der Ansprüche 2 bis 5.According to the invention, this object is achieved by that the bar from a fastener and a lip exists that with each other via a predetermined bending point are connected, tilting the lip in the direction the suction opening can be prevented by limiting elements, and the fastener from hard and the lip from soft material. Advantageous further developments of Invention result from the features of claims 2 until 5.
Nachstehend ist die Erfindung anhand einer bevorzugten Ausführungsform unter Bezugnahme auf die Zeichnungen beispielsweise näher beschrieben; es zeigenThe invention is based on a preferred one Embodiment with reference to the drawings for example described in more detail; show it
Fig. 1 eine Staubsaugerdüsen-Unterseite; Fig. 1 is a vacuum cleaner bottom;
Fig. 2 einen Querschnitt durch die Staubsaugerdüse nach der Linie II-II in Fig. 1;2 shows a cross section through the vacuum cleaner nozzle according to the line II-II in Fig. 1.
Fig. 3 bis 6 Querschnitte durch verschiedene Leisten. Fig. 3 to 6 cross sections through different strips.
In Fig. 1 und Fig. 2 ist eine Staubsaugerdüse mit dem Düsenunterteil (1) und der darin angeordneten Saugöffnung (2), dem Düsenoberteil (3) und dem Drehgelenkstutzen (4) dargestellt. Im hinteren Teil des Düsenunterteils (1) ist über die ganze Arbeitsbreite eine Leiste (5) in einer einfachen Nut (6) eingesetzt. Die Leiste (5) besteht aus einem Befestigungsteil (7) und einer Lippe (8), die über eine Sollbiegestelle (9) miteinander verbunden sind, wobei die Sollbiegestelle (9) als Filmscharnier ausgebildet ist. Damit die hochflexible Lippe (8) durch den Saugstrom nicht in Richtung der Saugöffnung (2) abkippt, sind mehrere Anschläge (10) als Begrenzungselemente am Düsenunterteil (1) vorgesehen. Sie begrenzen die Bewegungsmöglichkeit der Lippe (8) in Richtung der Saugöffnung (2).In Fig. 1 and Fig. 2, a vacuum cleaner nozzle with the nozzle lower part (1) and the suction opening arranged therein, (2), the nozzle upper part (3) and the pivot connection (4) is shown. In the rear part of the lower nozzle part ( 1 ) a bar ( 5 ) is inserted in a simple groove ( 6 ) over the entire working width. The strip ( 5 ) consists of a fastening part ( 7 ) and a lip ( 8 ) which are connected to one another via a predetermined bending point ( 9 ), the predetermined bending point ( 9 ) being designed as a film hinge. So that the highly flexible lip ( 8 ) does not tip in the direction of the suction opening ( 2 ) due to the suction flow, several stops ( 10 ) are provided as delimiting elements on the lower nozzle part ( 1 ). They limit the possibility of movement of the lip ( 8 ) in the direction of the suction opening ( 2 ).
Anstelle der Anschläge (10) am Düsenunterteil (1) kann auch, wie Fig. 4 und Fig. 5 zeigen, an der Lippe (8) unterhalb der Sollbiegestelle (9) eine Nase (11) ein- bzw. beidseitig angeformt sein. Diese Nase (11) begrenzt die Kippbewegung der Lippe (8) gegenüber dem Befestigungsteil (7) der Leiste (5) in einer bzw. beiden Bewegungsrichtungen (s. Fig. 4). Außerdem kann, wie in Fig. 6 dargestellt, die Lippe (8) auch außermittig, etwa am Rand des Befestigungsteiles (7), angeformt sein.Instead of the stops (10) at the nozzle lower part (1) can also, as Fig. 4 and Fig. 5 show underneath the predetermined bending point (9) turn a lug (11) on the lip (8) or be formed on both sides. This nose ( 11 ) limits the tilting movement of the lip ( 8 ) relative to the fastening part ( 7 ) of the bar ( 5 ) in one or both directions of movement (see FIG. 4). In addition, as shown in Fig. 6, the lip ( 8 ) can also be formed off-center, for example at the edge of the fastening part ( 7 ).
Mittels Preß- oder Extrudierverfahren wird das Befestigungsteil (7) zwecks einfacherer Anbringung aus einem Werkstoff mit höherem Härtegrad und die Lippe (8) aus weichem, verschleißfestem Material hergestellt. Mit einer Kunststofftype, wie PVC, kann durch Modifizierung des Härtegrades - Shorehärte - das Befestigungsteil (7) hart und die Lippe (8) weich einstückig gefertigt werden. Die Verwendung von PVC ist aber wegen des Verschleißes an der Lippe (8) nicht optimal. Durch die Verarbeitung von zwei unterschiedlichen Kunststofftypen wie Hart-PVC für das Befestigungsteil (7) und Polyurethan für die Lippe (8), ergeben sich für diese gute Verschleißeigenschaften.The fastening part ( 7 ) is made from a material with a higher degree of hardness and the lip ( 8 ) from a soft, wear-resistant material by means of a pressing or extrusion process. With a plastic type, such as PVC, by modifying the degree of hardness - Shore hardness - the fastening part ( 7 ) can be made hard and the lip ( 8 ) soft in one piece. However, the use of PVC is not optimal due to the wear on the lip ( 8 ). The processing of two different types of plastic, such as hard PVC for the fastening part ( 7 ) and polyurethane for the lip ( 8 ), results in good wear properties.
Außer bei Staubsaugerdüsen, kann die Leiste (5) auch bei Bürstsaugern oder Bürstvorsatzgeräten in gleicher Weise Verwendung finden.In addition to vacuum cleaner nozzles, the strip ( 5 ) can also be used in the same way for brush vacuums or brush attachments.
