Description

EinkaufswagenShopping venture
Die Erfindung betrifft einen Einkaufswagen mit Laufrollen und einem Griff dessen Oberfläche aus Kunststoff besteht.The invention relates to a shopping cart with wheels and a handle whose surface is made of plastic.
Bei derartigen Einkaufswagen kann es zu einer elektrostatischen Aufladung kommen.In such shopping cart can lead to an electrostatic charge.
Bei Schieben eines Einkaufswagens kann sich dieser je nach den jeweiligen Umweltbedingungen elektrostatisch aufladen.When pushing a shopping cart, it may become electrostatically charged depending on the 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 can therefore happen that the basket of the shopping cart builds up such a high potential that a person who touches this basket feels an electric shock.
Es gibt bekannte Einkaufswagen, bei denen das Griffrohr mit einem schwach leitenden Kunststof z.B. Weich - PVC ummantelt ist.There are known trolleys in which the handle tube is connected to a weakly 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 die Leitfähigkeit des Kunststoff Mantels zu gering ist, um die durch das Schieben des Einkaufswagens erzeugte Aufladung abzuführen.At a certain humidity, a part of the charge can be dissipated via this weakly conductive plastic. This has the disadvantage that especially at low humidity, the conductivity of the plastic sheath is too low to dissipate the charge generated by pushing the shopping cart.
Es ist Aufgabe der Erfindung, einen Einkaufswagen zu schaffen, bei dem die elektrostatische Aufladung unabhängig von den Umweltbedingungen vermieden wird.It is an object of the invention to provide a shopping cart, in which the electrostatic charge is avoided regardless of the environmental conditions.
Diese Aufgabe ist gelöst durch die kennzeichnenden Merkmale des Anspruchs 1 .This object is achieved by the characterizing features of claim 1.
Die Unteransprüche betreffen jeweils Weiterbildungen und/oder besonders vorteilhafte Ausgestaltungen der Erfindung.The subclaims 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 adopts the knowledge that the electrostatic charge arises when a customer holds the car on the isolated push handle and pushes the car. The insulated handle prevents the electrostatic charge generated when pushing over the customer's body from being diverted immediately in a completely harmless manner.
Aufbauend auf dieser Erkenntnis ist erfindungsgemäß vorgesehen, den Schiebegriff so auszugestalten, dass der Schiebegriff selbst eine ausreichend hohe Leitfähigkeit aufweist und der Schiebegriff leitend mit den anderen Teilen des Einkaufswagens verbunden ist. 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.Based on this finding, the invention provides the push handle in such a way that the push handle itself has a sufficiently high conductivity and the push handle is conductively connected to the other parts of the shopping cart. However, in the selection of plastics for sliding handles other criteria are also in the foreground and it has been shown that plastics which are electrically conductive are not as optimal in other respects as a handle for a shopping cart.
Es ist daher erfinderisch vorgesehen, für den Griff mehrere Materialien zu verwenden, von denen mindestens eines eine leitende Eigenschaft aufweist.It is therefore inventively provided to use for the handle several materials, of which at least one has a conductive property.
Eine andere Weiterbildung sieht vor, dass beim Herstellen des Griffes ein leitfähiges Material beispielsweise Graphit zugefügt wird, welches sich oberflächennah mit dem Kunststoff des Griffes vermischt.Another development provides that, when the handle is manufactured, a conductive material, for example graphite, is added, which mixes near the surface with the plastic of the handle.
Die leitenden Materialien sind vorzugsweise in dem Bereich des Griffes vorgesehen, der vom Kunden beim Schieben zwangsweise berührt wird.The conductive materials are preferably provided in the region of the handle, 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 purpose, a small portion of the handle, preferably at a location that is not directly in the field of view of the customer.
Der übrige Teil des Griffes kann aus einem anderen Material bestehen.The remainder of the handle may be made of a different material.
Nachfolgend wird ein mögliches Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert:Hereinafter, a possible embodiment of the invention is explained in more detail with reference to a drawing:
Der Griff 1 ist in teilweise geschnittener Darstellung gezeigt.The handle 1 is shown in a partially sectioned view.
Der Griff 1 hat ein im wesentlichen elliptisches Profil.The handle 1 has a substantially elliptical profile.
Durchgehend durch das Profil verläuft ein Bereich 2, der elektrisch leitend ist, der übrige Bereich 3 ist üblicherweise aus einem anderen Material hergestellt.Through the profile extends a region 2, which is electrically conductive, the remaining region 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, the conductive material is incorporated into the spray line, from which the handle is obtained at least on the surface.
Bei dem verwendeten Kunststoff kann es sich um PVC und bei dem leitenden Material kann es sich um ein kohlenstoffhaltiges Material oder um Metallpartikel handeln.The plastic used may be PVC and the conductive material may be a carbonaceous material or metal particles.
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 area for the conductive material is the area of the handle 1 that comes into 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 vorgesehgen the conductive connection between the handle 1 and the basket.
