Description

Bag-type hand cart

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bag-type hand cart, and more particularly, to a hand-operated cart which can be folded into a bag-shaped cover part to be stored therein.

BACKGROUND ART [0002] Generally, a cart is a carrying device or a moving device designed to carry objects having a predetermined weight, and is provided so as to be able to move while being held by hand or pulled.

These carts include large shopping carts used for shopping in large marts or small marts, shopping carts in the form of hand-carrying plastic baskets, home-use two or three-fold household hand carts, And heavy industrial conveyance carts for industrial use.

Here, the above-mentioned large shopping carts and industrial transportation carts are inconvenient for use in general households. In the case of basket shopping carts, they are lightweight and can be carried by hand. However, since they are not folding structures, There is a difficulty in reducing it, and it is inconvenient not to be portable in structure.

In addition, although the conventional hand cart of the present invention has a multi-folded folding structure, it is possible to reduce the volume of the body, which is not only inconvenient to carry but also requires a separate storage space for storage.

In order to solve such a problem, Korean Registered Utility Model No. 20-0477609 discloses a technique relating to a pocket type cart having a function of storing and transporting goods, but it is also possible to use a pocket structure in which a cart structure forms a storage pocket There is a possibility that the load is directly applied, and therefore, there is a high possibility of deformation and breakage, so that it is difficult to maintain a constant external shape of the storage pocket.
