Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a shopping cart for food and non-food shopping, the storage volume of which is adjustable so that in the configuration storage, the latter has a small footprint. It also relates to a foldable trolley for the transport of goods adapted to carry such a basket. It relates more particularly to such a cart facilitating the port and removal of the basket in the trunk of a vehicle.

BACKGROUND ART Various devices are known to assist in the storage and transportation of goods in grocery stores and supermarkets, which range from baskets to trolleys, the latter offering significant transport capacity for the purchase of many goods and / or bulky items.

The current baskets have many disadvantages, in particular because of the limited number and / or the limited volume of goods that can be stored in these baskets. There are thus baskets overloaded with an excess of articles leading the consumer to carry articles by hand or to carry in addition to their basket, another basket, which is uncomfortable for the latter. In addition, this excess of articles can lead to rapid deterioration of the basket structure and accidental spillage of some of the items unstablely placed at the top of stored goods 3031088 2 in the basket. In addition, there are individual baskets with a higher storage volume but they are bulky and occupy a large volume when stored for example in the trunk of an automobile. In addition, trolleys may be inadequate when the number of goods to be purchased is low and does not require such a large storage volume.

In order to allow customers to carry a large number of items in a single cart, the cart baskets are also deep. However, in order to pay for their purchases, it is necessary for customers to take out the products and goods contained in the basket for disposal on the crate mats.

Now, it is observed that customers are obliged to bend over the walls of the basket to access products and goods placed in the bottom of the basket, especially when they are of small dimensions. In addition, goods and bulky or heavy products require 20 to large arms levers. For some categories of customers (elderly, pregnant women, people of modest size or suffering from back, ...), this step can be laborious and uncomfortable. These baskets are therefore not very functional especially since customers usually have to put their purchases in the cart to empty it again at the trunk of their car. The present invention aims to overcome these various disadvantages of the prior art by providing a shopping cart, simple in its design and its operating mode, economic and allowing an adjustment of its storage volume to best adapt this volume based the number and / or volume of goods stored there. Another object of the present invention is a foldable carriage for carrying such a basket ensuring easy attachment and release thereof.
