Duplex Folding Shopping Cart {Duplex Folding Shopping Cart}

The present invention relates to a multi-layer folding shopping cart that can store and store goods by dividing them into upper and lower spaces, and can be moved and conveniently stored in a narrow space by simply folding them. When you want to move, you can conveniently store and load many items by dividing them into separate upper and lower storage spaces, and you can simply fold the upper and lower middle parts together. It is about a multi-layer folding shopping cart that can be used.

In general, when purchasing goods at a hypermarket, not only do they purchase various types of goods, but also the amount of purchase is large. Therefore, buyers usually drag a shopping cart to select items to purchase and store them in the shopping cart for convenient mobile shopping.

As such, a shopping cart conveniently used as a means for shopping for purchasing a large quantity of goods or for moving a plurality of goods, as shown in the normal shopping cart illustrated in FIG. 8, is a basket of storage space for loading goods to be purchased. (1), a handle configured on one side of the basket, and a cart frame 2 arranged on the lower side of the basket 1 to support the basket 1 and facilitate the movement of the shopping cart, and the bottom side of the cart frame 2 It is based on the caster (2a) of the.

In addition, buyers push shopping carts like this to select items to purchase from large marts and load them into the basket (1), and then drag the shopping cart loaded with multiple items to the checkout counter to calculate the price for the items in the basket (1). Then, if there is a large amount of purchases of items settled at the cashier, rather than using them directly in the shopping bag, first load them into the basket (1) of the shopping cart, move to the place to be packed, and pack them in multiple shopping bags and pack them in the parking lot It can be said that moving by vehicle is common.

On the other hand, shopping carts that do not have baskets themselves are loaded by directly loading and loading items that are relatively small in size or quantity compared to shopping cards with baskets on the upper part of the frame, or in a separate basket. It is used, and it is generally provided as a folding structure to increase the efficiency of storage and transportation. There is no problem in storing and loading small quantities or large items, but it is difficult to store and move large quantities or large items. It was inevitable to be limited, and of course, because it is small, it is bound to be functionally and structurally limited to use it without inconvenience for shopping for various items or other camping.

It is composed of a functional folding bracket.

In particular, when the product storage shelf is unfolded, the binding support end is protruded so that the folding hinge can be hinged so that the folding hinge can be pivoted while the contact surface portion of the left and right symmetry is closely supported on the same line. The product storage shelf, which has a layer structure, has technical features even though it can be configured to be applied to a multi-layer structure of three or more layers.

In addition, the multi-joint folding bracket, in which the folding and fixing bracket, which is the intermediate part, is bound to the vertical folding movable support so that the unfolding and folding operations of the product storage shelf can be operated stably is attached to the inclined support on both sides in the inclined direction As the folding and binding brackets, which are both ends, are bound, the folding link brackets are respectively bound between the folding and binding brackets on both sides centering on the folding and fixing bracket in the center, while the storage fixing post in one vertical direction and the article in the horizontal direction A response structure in which a separate gas shock absorber is installed at an angle between the storage shelves may also be implemented.

According to the multi-layered folding shopping cart according to the present invention with such a compositional principle, it has a left-right symmetrical structure when storing and moving goods such as camping as well as shopping. In addition to expandability and convenience of storage, it is possible to store and store goods, as well as after storing and moving goods such as shopping and camping, simply fold them around the contact surface in the middle of the foldable double-layer goods storage shelf with a symmetrical structure to connect to the trunk of the vehicle. Even in the same narrow space, differentiated operational effects completely different from existing shopping carts such as storage and portability, which can be conveniently stored and moved by reducing the height without any difficulty, can be provided.

In other words, in order to improve and solve various inconveniences that had to be limited in terms of functional and structural aspects of general shopping carts in which the existing basket and cart frame are integrated, or small shopping baskets capable of storing and moving relatively small or small amounts of items, etc. As this product was developed, when you want to store and move a large number of large and small items such as shopping or camping, you can conveniently store and load many items by dividing them into separate upper and lower storage spaces, and simply fold the middle folding part to the maximum cart. It is expected that differentiated effects that are difficult to expect from existing shopping carts, such as loading and storage, which can be conveniently moved and stored without any difficulty even in a narrow space such as a car trunk, as the height of the product can be reduced. do.

This means that when shopping at a mart or camping outdoors, various items are stored in a detachable basket of a shopping cart, and the calculated items are put in a separate paper box or shopping bag and moved to the trunk of the vehicle to store and store the items. Without the painful and difficult inconvenience of bringing a paper box or shopping bag home, you can store the items you have stored and calculated directly on the shopping cart's product storage shelf provided in the upper and lower separated storage space, or put them as they are in a separate basket and store them in the product storage shelf. After moving to the side, the symmetrical structured upper and lower product storage shelves with a folding function can be simply folded together to drastically reduce the overall height and size of the shopping cart, so that it can be conveniently inserted into the trunk space of the vehicle for storage and transportation. The shopping cart containing the shopping cart can be taken out of the trunk of the vehicle in its original location and unfolded in the form of a normal cart to its original height and size. It is expected that all existing shopping carts, which could not be structurally put into the trunk of a vehicle and stored, so that shopping or moving storage could not be solved, structurally solving all the inconveniences.
