Embodiment Construction

[0020] [0020] The handle 1 has a substantially oval shape. The conductive area 2 extends along the full length of the profile; the remaining area 3 is usually made of another material.

[0021] [0021] The handle is obtained by incorporating the conductive material, at least superficially, into the injection molded part using coextrusion.

[0022] [0022] The plastic used may be polyvinyl chloride, and the conductive material used may be carbonaceous material or metal particles.

[0023] [0023] A preferred area for conductive material is the area of ​​the handle 1 which is in contact with the customer's palm and / or thumb when the customer pushes the shopping trolley in front of him.

[0024] [0024] Although not shown in the figures, the present invention provides an electrically conductive connection between the handle 1 and the basket.

Abstract

The invention relates to a shopping trolley having castors and a handle the surface of which consists of plastic. The surface of the handle (1) consists of one or more different materials (2, 3), at least one of said materials (2) having conductive properties.

Description

technical field [0001] [0001] The present invention relates to a shopping cart having a plurality of castor wheels and a handle whose surface layer is formed of plastic. Background technique [0002] [0002] Static electricity can occur on such shopping carts. [0003] [0003] When a shopping cart is pushed, the shopping cart may become charged with static electricity depending on the corresponding environmental conditions. [0004] [0004] This therefore results in such a high potential being built up on the basket of the shopping cart that someone would receive a shock if they touched the basket. [0005] [0005] Some shopping trolleys are known to have handles coated with poorly conductive plastics, such as flexible polyvinyl chloride. [0006] [0006] Under a certain air humidity, some charges can be dissipated through this poorly conductive plastic. This has the disadvantage that, especially at low air humidity, the electrical conductivity of the plastic casing is too low...
