Abstract

The trolley has a roller wheel and a handle (1) whose surface is made of synthetic materials (2, 3). The synthetic material (2) having a conductive characteristic is provided in a lateral section of the handle. The handle is conductively connected with a trolley basket and immediately discharges the electrostatic charge generated while pushing the trolley by a customer via the customer body.

Description

Die Erfindung betrifft einen Einkaufswagen mit Laufrollen und einem Griff dessen Oberfläche aus Kunststoff besteht.The The invention relates to a shopping cart with rollers and a Handle its surface made of plastic.

Bei derartigen Einkaufswagen kann es zu einer elektrostatischen Aufladung kommen.at Such shopping cart may cause an electrostatic charge come.

Bei Schieben eines Einkaufswagens kann sich dieser je nach den jeweiligen Umweltbedingungen elektrostatisch aufladen.at Pushing a shopping cart may vary depending on the particular one To electrostatically charge environmental conditions.

Es kann daher vorkommen, dass der Korb des Einkaufswagens ein so hohes Potential aufbaut, dass eine Person, die diesen Korb berührt einen Stromschlag verspürt.It It can therefore happen that the basket of the shopping cart such a high Potential builds up that a person who touches this basket is electrocuted felt.

Es gibt bekannte Einkaufswagen, bei denen das Griffrohr mit einem schwach leitenden Kunststof z.B. Weich – PVC ummantelt ist.It are known cart, in which the handle tube with a weak conductive plastic e.g. Soft PVC is sheathed.

Bei einer gewissen Luftfeuchtigkeit kann über diesen schwach leitenden Kunststoff ein Teil der Ladung abgeleitet werden. Dies hat den Nachteil, dass speziell bei geringer Luftfeuchtigkeit das gewünschte Ergebnis nicht eintritt.at a certain humidity can over this weakly conductive Plastic will be diverted a portion of the cargo. This has the disadvantage that especially at low humidity the desired result does not occur.

Es ist Aufgabe der Erfindung, einen Einkaufswagen zu schaffen, bei dem die elektrostatische Aufladung unabhängig von den Umweltbedingungen vermieden wird.It The object of the invention to provide a shopping cart, in which avoided the electrostatic charge regardless of the environmental conditions becomes.

Diese Aufgabe ist gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.These Task is solved by the characterizing features of claim 1.

Die Unteransprüche betreffen jeweils Weiterbildungen und/oder besonders vorteilhafte Ausgestaltungen der Erfindung.The under claims each relate to further developments and / or particularly advantageous Embodiments of the invention.

Die Erfindung macht sich die Erkenntnis zu eigen, dass die elektrostatische Ladung entsteht, wenn ein Kunde den Wagen am isolierten Schiebegriff hält und dabei den Wagen schiebt. Der isolierte Griff verhindert, dass die beim Schieben entstehende elektrostatische Aufladung über den Körper des Kunden in völlig ungefährlicher Weise sofort wieder abgeleitet wird.The Invention embraces the knowledge that the electrostatic Charge arises when a customer drives the car on the insulated push handle stops and while pushing the car. The insulated handle prevents the when pushing electrostatic charge on the body of the customer in total hazardous Way immediately derived again.

Aufbauend auf dieser Erkenntnis ist erfindungsgemäß vorgesehen, den Schiebegriff so auszugestalten, dass der Schiebegriff leitend mit dem Korb verbunden ist.Building On this finding, the invention provides the push handle to design so that the push handle conductively connected to the basket is.

Bei der Auswahl der Kunststoffe für Schiebgriffe stehen jedoch auch andere Kriterien im Vordergrund und es hat sich gezeigt, dass Kunststoffe, die elektrisch leitend sind, in anderer Beziehung nicht so optimal als Griff für einen Einkaufswagen sind.at the selection of plastics for Push handles are also other criteria in the foreground and it has been shown that plastics that are electrically conductive are, in other respects, not as optimal as a handle for one Shopping cart are.

Es ist daher erfinderisch vorgesehen, für den Griff mehrere Kunststoffmaterialien zu verwenden, von denen mindestens eines eine leitende Eigenschaft aufweist.It is therefore provided inventive, for the handle of several plastic materials to use, at least one of which is a conductive property having.

Die leitenden Materialien sind vorzugsweise in dem Bereich des Griffes vorgesehen, der vom Kunden beim Schieben zwangsweise berührt wird.The conductive materials are preferably in the region of the handle provided, which is forcibly touched by the customer when pushing.

Hierfür reicht ein kleiner Teilbereich des Griffes, vorzugsweise an einer Stelle, die nicht direkt im Blickfeld des Kunden liegt.For this is enough a small portion of the handle, preferably at one point, which is not directly in the customer's field of vision.

Der übrige Teil des Griffes kann aus einem anderen Material bestehen.The remaining part The handle can be made of a different material.

Nachfolgend wird ein mögliches Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert:following becomes a possible embodiment of the invention explained in more detail with reference to a drawing:

Der Griff 1 ist in teilweise geschnittener Darstellung gezeigt.The handle 1 is shown in partial section.

Der Griff 1 hat ein im wesentlichen eliptisches Profil.The handle 1 has a substantially elliptical profile.

Durchgehend durch das Profil verläuft ein Bereich 2, der elekrtisch leitend ist, der übrige Bereich 3 ist üblicherweise aus einem anderen Material hergestellt.Through the profile runs an area 2 which is electrically conductive, the remaining area 3 is usually made of a different material.

Durch Koextrusion ist das leitende Material in den Spritzstrang, aus welchem der Griff gewonnen wird zumindest an der Oberfläche eingearbeitet.By Coextrusion is the conductive material in the extrusion line, from which the handle is at least worked on the surface.

Ein bevorzugter Bereich für das leitende Material ist der Bereich des Griffes 1, der mit dem Handballen und / oder Daumen des Kunden in Kontakt kommt, wenn der Kunde den Einkaufswagen so vor sich her schiebt.A preferred range for the conductive material is the area of the handle 1 which comes in contact with the customer's palm and / or thumb when the customer pushes the shopping cart in front of him.

In der Figur nicht gezeigt, aber dennoch vorgesehgen ist die leitende Verbindung zwischen Griff 1 und dem Korb.Not shown in the figure, but nevertheless envisaged is the conductive connection between handle 1 and the basket.
