Description

Staubsauger vacuum cleaner
Die Erfindung bezieht sich auf einen mit Laufrollen ausgestatteten Staubsauger.The invention relates to a vacuum cleaner equipped with castors.
Aus der US 4 934 017 ist ein Staubsauger bekannt, der Laufrollen hat. Die Laufrollen weisen Rippen auf, die von einer Nabe des Laufrades ausgehend, mit einer äußeren Lauffläche verbunden sind und der Laufrolle die erforderliche Stabilität verleihen.From US 4 934 017 a vacuum cleaner is known which has rollers. The rollers have ribs, which start from a hub of the impeller and are connected to an outer tread, and give the roller the required stability.
Es ist die Aufgabe der Erfindung, bei einem Staubsauger der eingangs genannten Art die Laufeigenschaften des Staubsaugers weiter zu verbessern.It is the object of the invention to further improve the running properties of the vacuum cleaner in a vacuum cleaner of the type mentioned.
Diese Aufgabe wird bei einem erfindungsgemäßen Staubsauger dadurch gelöst, dass die Laufrollen eine zwischen einem Laufring und einer Nabe einen geschwungenen Querschnitt aufweisende Wand haben.This object is achieved in a vacuum cleaner according to the invention in that the rollers have a wall with a curved cross section between a race and a hub.
Durch die geschwungene Wand zwischen der Nabe und dem Laufring wird den Laufrollen eine hohe Elastizität verliehen. Selbst wenn die Laufrollen aus einem harten Material bestehen, ist die geschwungene Form der Wand imstande, Stöße abzufedern.Due to the curved wall between the hub and the race, the rollers are given a high degree of elasticity. Even if the casters are made of a hard material, the curved shape of the wall is able to absorb shocks.
Die Laufrollen haben einen einfachen Aufbau und lassen sich daher kostengünstig herstellen.The rollers have a simple structure and can therefore be manufactured inexpensively.
Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Advantageous further developments result from the subclaims.
Besonders vorteilhaft ist eine Ausführungsform des Staubsaugers, bei der die Wand eine S- oder eine Z-förmige Struktur im Querschnitt aufweist. Durch diese Form wird bei geringem Materialverbrauch ein hohes Maß an Elastizität erzielt.An embodiment of the vacuum cleaner is particularly advantageous in which the wall has an S or a Z-shaped structure in cross section. This shape achieves a high degree of elasticity with low material consumption.
In einer anderen vorteilhaften Weiterbildung sind zusätzlich Verstärkungsrippen vorgesehen, die auf wenigstens einer der beiden Stirnseiten angeordnet sind. Dabei gehen die Verstärkungsrippen jeweils von der Wand in ihrem geschwungenen Bereich aus. Durch die Verstärkungsrippen erhält die Wand eine höhere Stabilität. Um die Elastizität aber nicht zu reduzieren, sind die Rippen nicht mit der Nabe oder mit dem Laufring verbunden.In another advantageous development, reinforcing ribs are additionally provided, which are arranged on at least one of the two end faces. The reinforcing ribs each extend from the wall in their curved area. The reinforcement ribs give the wall greater stability. In order not to reduce the elasticity, the ribs are not connected to the hub or to the race.
Alternativ zu den von dem geschwungenen Bereich der Wand nach innen zu der Nabe gerichteten Rippen gehen diese in einer anderen Ausführungsform von der Nabe aus und sind gegen den geschwungenen Bereich der Wand gerichtet. Auch in diesem Fall sind die Rippen nicht mit der geschwungenen Wand verbunden, um die Elastizität nicht zu verrringern.As an alternative to the ribs directed inwards from the curved area of the wall towards the hub, in another embodiment these ribs extend from the hub and are directed against the curved area of the wall. In this case, too, the ribs are not connected to the curved wall in order not to reduce the elasticity.
In einer anderen Weiterbildung der Erfindung hat der Laufring auf seiner Lauffläche eine ballige Kontur. Auch durch diese Maßnahme wird die Elastizität der Laufrollen unterstützt.In another development of the invention, the race has a spherical contour on its tread. This measure also supports the elasticity of the rollers.
Bei der Erfindung wird auch bei Einsatz eines harten Materials eine hohe Elastizität erreicht. So kann die Laufrolle beispielsweise kostengünstig aus Polypropylen (PP) oder einer seiner Co-polymere hergestellt sein.In the invention, high elasticity is achieved even when using a hard material. For example, the roller can be made inexpensively from polypropylene (PP) or one of its copolymers.
In einer vorteilhaften Variante weist der Laufring der Laufrolle eine Oberfläche aus weichelastischem Material auf. Dadurch wird eine zusätzliche Dämpfung erzielt und es kann auch eine verbesserte Rutschfestigkeit der Laufrolle auf glatten Böden erreicht werden. Vorzugsweise ist eine Lauffläche aus weichelastischem Kunststoffmaterial an den Laufring angespritzt. Diese Lauffläche kann kostengünstig im Zweikomponenten- Spritzgussverfahren an den Laufring angespritzt ist. Als geeignete Kunststoffmaterialien können insbesondere thermoplastische Elastomere (TPE) und Materialien auf Kautschukbasis verwendet werden.In an advantageous variant, the running ring of the roller has a surface made of flexible material. This results in additional damping and an improved slip resistance of the roller on smooth floors. A running surface made of flexible plastic material is preferably injection molded onto the running ring. This tread can be inexpensively molded onto the race in a two-component injection molding process. In particular, thermoplastic elastomers (TPE) and rubber-based materials can be used as suitable plastic materials.
Nachstehend wird die Erfindung in einem Ausführungsbeispiel anhand der Zeichnungen näher erläutert. Diese zeigen:The invention is explained in more detail in an exemplary embodiment with reference to the drawings. These show:
Fig. 1 , 2 eine Laufrolle für einen Staubsauger in perspektivischen Ansichten von der Vorderseite und der Rückseite,1, 2 a roller for a vacuum cleaner in perspective views from the front and the back,
Fig. 3 die Laufrolle in einer Schnittansicht A-A gemäß Fig. 4 und3 shows the roller in a sectional view A-A according to FIGS. 4 and
Fig. 4 die Laufrolle in der Draufsicht auf die Rückseite,4 the roller in a top view of the back,
Fig. 5 eine Laufrolle mit einer Lauffläche aus weichelastischem Material. Ein Staubsauger weist Laufrollen auf. Die Laufrollen sind aufgebaut wie eine Laufrolle 1 (Fig. 1). Die Laufrolle 1 weist eine Nabe 2 auf, über die sie auf einer mit dem Gehäuse des Staubsaugers verbundenen Achse gleitend oder über Kugel- oder Wälzlager gelagert verbunden ist. Die Laufrolle besteht aus einem Kunststoff, insbesondere einem harten Kunststoff wie Polypropylen, sie kann jedoch auch aus einem stärker elastischen Kunststoff bestehen. Die Nabe 2 hat zur Achse hin auf ihrer Vorderseite einen kreisförmigen Vorsprung 21 und auf ihrer Rückseite einen ebenfalls kreisförmigen Vorsprung 22.Fig. 5 is a roller with a tread made of soft elastic material. A vacuum cleaner has castors. The rollers are constructed like a roller 1 (Fig. 1). The roller 1 has a hub 2, via which it is slidably connected on an axle connected to the housing of the vacuum cleaner or supported by ball or roller bearings. The roller is made of a plastic, in particular a hard plastic such as polypropylene, but it can also consist of a more elastic plastic. The hub 2 has a circular projection 21 toward the axis on its front side and a likewise circular projection 22 on its rear side.
An die Nabe 2 schließt sich eine Wand 3 an, die die Nabe 2 mit einem Laufring 4 verbindet. Die Wand 3 weist einen ersten Bereich 30 auf, der sich in radialer Richtung von der Nabe 2 auf der Vorderseite bis nahe an die Mitte des Radius der Laufrolle 1 erstreckt. Daran schließt sich ein zweiter Bereich 31 an, der sich von der Vorderseite schräg zu der Rückseite der Laufrolle 1 erstreckt. Die Schräge des Bereichs 31 lässt sich unterschiedlich wählen. Der Bereich 31 kann auch koplanar zu einer der beiden Mantelflächen der Nabe 2 oder koplanar zu einer der beiden Mantelflächen des Laufrings 4 verlaufen.A wall 3 connects to the hub 2 and connects the hub 2 to a race 4. The wall 3 has a first region 30 which extends in the radial direction from the hub 2 on the front side to close to the center of the radius of the roller 1. This is followed by a second region 31, which extends obliquely from the front to the rear of the roller 1. The slope of the area 31 can be selected differently. The region 31 can also run coplanar to one of the two lateral surfaces of the hub 2 or coplanar to one of the two lateral surfaces of the race 4.
An den Bereich 31 schließt sich ein Bereich 32 (Fig. 2), der sich in radialer Richtung von dem Bereich 31 auf der Rückseite der Laufrolle 1 bis zu dem Laufring 4 erstreckt. Somit verbindet die Wand 3 durch ihre drei Bereiche 30, 31 und 32 die Nabe mit dem Laufring 4.A region 32 (FIG. 2) adjoins the region 31, which extends in the radial direction from the region 31 on the rear side of the roller 1 to the race ring 4. The wall 3 thus connects the hub to the race 4 through its three regions 30, 31 and 32.
Zur Unterstützung der Stabilität der Laufrolle 1 sind Rippen 5, 6 vorhanden. Die Rippen 5 erstrecken sich von dem Bereich 31 der Wand 3 in Richtung zur inneren Mantelfläche des Laufrings 4, berühren diesen jedoch nicht. Einzig im Fall starker Gewichtsbelastung können die Rippen 5 die Mantelfläche berühren.Ribs 5, 6 are provided to support the stability of the roller 1. The ribs 5 extend from the region 31 of the wall 3 in the direction of the inner lateral surface of the race 4, but do not touch it. Only in the case of heavy weight loads can the ribs 5 touch the outer surface.
Die Rippen 6 erstrecken sich von dem Bereich 32 der Wand 3 in Richtung zur äußeren Mantelfläche der Nabe 2. Auch die Rippen 6 berühren die Mantelfläche der Nabe 2 nicht, können jedoch im Falle starker Gewichtsbelastung an diese stoßen.The ribs 6 extend from the area 32 of the wall 3 in the direction of the outer circumferential surface of the hub 2. The ribs 6 also do not touch the circumferential surface of the hub 2, but can hit them in the event of heavy weight.
Alternativ zu dieser Anordnung der Rippen 6 können Rippen auch auf der äußeren Mantelfläche der Nabe 2 angeordnet sein und in Richtung zu dem Bereich 31 der Wand 3 ragen, ohne diese zu berühren, außer im Fall starker Gewichtsbelastung. Die Laufrolle hat vorzugsweise eine ballige Lauffläche 41.As an alternative to this arrangement of the ribs 6, ribs can also be arranged on the outer circumferential surface of the hub 2 and protrude in the direction of the region 31 of the wall 3 without touching it, except in the case of heavy weight. The roller preferably has a spherical tread 41.
Die geschwungene Form der Wand 3 ist entweder Z-förmig (vgl. Fig. 3, 4) oder S-förmig. Auch andere geschwungene Formen sind denkbar. Insbesondere ist auch eine Doppel-S- Form oder eine Doppel-Z-Form möglich.The curved shape of the wall 3 is either Z-shaped (see. Fig. 3, 4) or S-shaped. Other curved shapes are also conceivable. In particular, a double S shape or a double Z shape is also possible.
Durch die Erfindung wird eine elastische Laufrolle 1 mit einer Nabe 2 und einem Laufπng 4 geschaffen. Die Nabe 2 und der Laufring 4 sind durch eine S- oder Z-förmig geschwungene Wand 3 mit einander verbunden. Zur Verstärkung der Wand 3 oder der Nabe 2 sind Rippen 5, 6 vorgesehen.The invention provides an elastic roller 1 with a hub 2 and a roller 4. The hub 2 and the race 4 are connected to each other by an S or Z-shaped curved wall 3. Ribs 5, 6 are provided to reinforce the wall 3 or the hub 2.
Der Laufring 4 weist eine Oberfläche aus weichelastischem Material auf (Fig. 5). Eine weichelastische Lauffläche 41 aus einem geeigneten Kunststoffmaterial ist direkt an den Laufring 4 angeformt. In einfacher Weise kann die weichelastische Lauffläche 41 im Zweikomponenten-Spritzgußverfahren zusammen mit der Laufrolle 1 hergestellt sein. Der Laufring 4 ist an seiner Oberfläche mit einer umlaufenden Vertiefung 51 versehen, in die das weichelastische Material angeformt ist. The race 4 has a surface made of flexible material (FIG. 5). A soft elastic tread 41 made of a suitable plastic material is molded directly onto the race 4. In a simple manner, the soft elastic tread 41 can be produced together with the roller 1 in a two-component injection molding process. The race 4 is provided on its surface with a circumferential recess 51, into which the flexible material is molded.
