Description

Die Erfindung betrifft eine Lenkrolle, insbesondere eine freilaufende Lenkrolle, mit Zwillingsrädern, mit einem Gehäuse mit einer im Wesentlichen vertikal ausgerichteten, oberseitigen Zapfenöffnung zur Aufnahme eines Drehzapfens zur Verbindung der Rolle mit einem Möbelstück oder einem anderen Gegenstand, und mit einem das Gehäuse quer zur Zapfenöffnung durchsetzenden, die Räder tragenden Achsbolzen.The invention relates to a castor, in particular a free-running castor, with twin wheels, with a housing having a substantially vertically oriented upper-side pin opening for receiving a pivot for connecting the roller with a piece of furniture or other object, and with a housing transversely to the pin opening penetrating, the wheels bearing axle.

Lochrollen sind Rollen mit einer axialen Durchtrittsöffnung im Bereich der ansonsten üblichen Radachse und einer Radlagerung, die radial im Bereich des Radmantels angeordnet ist. Die ”offene” Bauweise wird oft als optisch ansprechend empfunden, allerdings führt der konstruktive Aufwand zu erhöhten Herstellungskosten und der Rolleninnenbereich ist verschmutzungsanfällig.Puncture rollers are rollers with an axial passage opening in the region of the otherwise usual wheel axle and a wheel bearing, which is arranged radially in the region of the wheel jacket. The "open" design is often perceived as visually appealing, but the design effort leads to increased production costs and the inner roller area is prone to contamination.

Ausgehend hiervon besteht die Aufgabe der vorliegenden Erfindung darin, eine Rolle der eingangs genannten Art zu entwickeln, die den optischen Eindruck einer Lochrolle aufweist, jedoch konstruktiv einfacher gestaltet ist.Proceeding from this, the object of the present invention is to develop a role of the type mentioned, which has the visual impression of a perforated roll, but is designed structurally simpler.

Zur Lösung dieser Aufgabe wird die in Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To solve this problem, the feature combination specified in claim 1 is proposed. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Die Erfindung geht vor allem von der Erkenntnis aus, dass der optische Effekt einer Lochrolle auch dadurch annähernd erreicht werden kann, dass eine Spiegelfläche den Untergrund, auf dem sich die Rolle befindet, reflektiert. Erfindungsgemäß wird daher vorgeschlagen, dass die Rolle eine ebene, spiegelreflektierende Achsabdeckung aufweist. Wichtig ist, dass die Achsabdeckung eben ausgebildet ist, da eine gewölbte Spiegelfläche nicht den erwünschten optischen Eindruck erzeugt.The invention is based above all on the recognition that the optical effect of a perforated roll can also be approximately achieved in that a mirror surface reflects the substrate on which the roll is located. According to the invention it is therefore proposed that the roller has a flat, mirror-reflecting axle cover. It is important that the Achsabdeckung is flat, as a curved mirror surface does not produce the desired visual impression.

In bevorzugter Ausgestaltung der Erfindung ist die ebene, spiegelrelektierende Achsabdeckung als Radkappe ausgebildet. Dies ermöglicht eine einfache Montage und im Bedarfsfall einen Austausch der Achsabdeckung. Weiterhin ist die ebene, spiegelreflektierende Achsabdeckung bevorzugt durch eine Metallfläche, beispielsweise eine polierte Edelstahl- oder Chromfläche, gebildet ist. Eine kostengünstige Herstellung kann dadurch erreicht werden, wenn Metallfläche eine auf einen Kunststoffträger aufgebrachte Beschichtung ist. Es hat sich gezeigt, dass der erwünschte optische Effekt besonders dann auftritt, wenn die spiegelreflekierende Achsabdeckung axial in Richtung Radmitte gegenüber dem Radmantel bzw. der Lauffläche versetzt oder versenkt ist.In a preferred embodiment of the invention, the planar, mirror-like axle cover is designed as a hubcap. This allows easy installation and, if necessary, replacement of the axle cover. Furthermore, the flat, mirror-reflecting axle cover is preferably formed by a metal surface, for example a polished stainless steel or chrome surface. A cost-effective production can be achieved if metal surface is applied to a plastic carrier coating. It has been found that the desired optical effect occurs especially when the mirror-reflecting axle cover is displaced or sunk axially in the direction of the wheel center relative to the wheel casing or the running surface.

Im Folgenden wird die Erfindung anhand der in der Zeichnung in schematischer Weise dargestellten Ausführungsbeispiele näher erläutert. Es zeigtIn the following the invention will be explained in more detail with reference to the embodiments schematically illustrated in the drawing. It shows

1 eine perspektivische Ansicht einer Lenkrolle mit Zwillingsrädern, die jeweils eine spiegelreflektierende Achsabdeckung aufweisen, und 1 a perspective view of a caster with twin wheels, each having a mirror-reflecting axle cover, and

2a und b eine Seitenansicht und einen Querschnitt durch die Rolle gemäß 1. 2a and b is a side view and a cross section through the roller according to 1 ,

Die in der Zeichnung dargestellte Rolle besteht im Wesentlichen aus einem Gehäuse 10 mit einer Zapfenöffnung zur Aufnahme eines Drehzapfens oder Laufstifts 12, mittels dessen die Rolle an einem Möbelstück oder dergleichen drehbar befestigt wird, und aus zwei Rädern 14, 14' mit rohrförmigen Naben 16, 16', die auf die freien Enden eines Achsbolzens 18 aufgesteckt sind und sich auf diesem drehen. Die Räder bestehen aus einem Radkörper mit aufgespritzten Laufflächen aus einem dem Einsatzzweck angepassten Material, beispielsweise einem weichen Material für den Einsatz auf harten Böden oder einem harten Material zum Einsatz auf Teppichböden o. dgl.The role shown in the drawing consists essentially of a housing 10 with a pin opening for receiving a pivot or race pin 12 , by means of which the roller is rotatably attached to a piece of furniture or the like, and two wheels 14 . 14 ' with tubular hubs 16 . 16 ' on the free ends of a journal 18 are plugged in and turn on this. The wheels consist of a wheel body with sprayed running surfaces made of a material adapted to the purpose, for example a soft material for use on hard floors or a hard material for use on carpets o. The like.

Die Räder 14, 14' weisen weiterhin Radkappen 20, 20' auf, die in dafür vorgesehene Durchbrechungen der Radkörpers eingerastet sind. Die Radkappen 20, 20' sind beispielsweise als Spritzgussteile aus Kunststoff hergestellt. Ihre nach außen gewandten, ebenen Sichtflächen sind mit einer spiegelreflektierenden Beschichtung, etwa einer Chrombeschichtung, versehen. Die Sichtflächen der Radkappen sind weiterhin gegenüber dem äußeren Wulst des Radkörpers axial in Richtung Radmitte versenkt angeordnet. Im Einsatz der Rolle entsteht durch die Spiegelfläche, die den Untergrund reflektiert, der optische Eindruck einer Lochrolle, ohne dass der erhebliche konstruktive Aufwand einer solchen Rolle erforderlich ist. Weiterhin schützen die Radkappen das Innere der Rolle vor Verschmutzungen.The wheels 14 . 14 ' continue to have hubcaps 20 . 20 ' on, which are engaged in designated openings of the wheel body. The hubcaps 20 . 20 ' are made, for example, as injection-molded parts made of plastic. Their outwardly facing, flat viewing surfaces are provided with a mirror-reflective coating, such as a chrome coating. The visible surfaces of the hubcaps are further arranged opposite the outer bead of the wheel body axially sunk toward the center of the wheel. In the use of the role created by the mirror surface, which reflects the background, the visual impression of a hole role, without the considerable design effort of such a role is required. Furthermore, the hubcaps protect the interior of the roller from contamination.
