Description

Foldable wagon with two-stage storage structure {FOLDING WAGON WITH 2-STAGE STORAGE STRUCTURE}

The present invention relates to a folding wagon, and more specifically, through a configuration using a bellows-type folding structure, a more efficient storage function can be achieved by easily reducing the volume of the product even in an integrated state with a storage basket as is, and each of the different A more expanded storage capacity can be expected through the configuration of the storage space in a two-tier structure, and at the same time, two-tier storage can respond more appropriately according to the various storage characteristics of storage objects of different sizes and shapes. It relates to a folding wagon having a structure.

In general, a wagon is a general term for a four-wheeled vehicle with four wheels and a body capable of carrying objects, and cart-shaped wagons have emerged and are widely used as daily transportation tools.

These wagons are used to transport heavy items, bulky items, children and similar transport objects.

For example, families with young children such as infants and children use wagons, which are developed in various forms, when going out or for walks, and recently, due to the camping craze, wagons are being widely used to transport camping equipment or props.

In order to unfold the wagon frame that has been folded and stored in the existing wagon, the lock/release button is pressed and the frame is rotated. Due to the structure of the main body frame, the existing wagon is manufactured so that at least 3 to 4 operations are performed, and a separately separated canopy or storage basket is also installed. It has the disadvantage of requiring a lot of work on the part of the guardian, making it difficult to install quickly and making it less portable and portable.

Also, on the contrary, it is not easy to fold the wagon after use, so there is a problem that guardians or acquaintances who have not used the wagon have difficulty in installation and storage.

In addition, the existing wagon has a complicated combination structure of wheels and storage baskets, so it requires a lot of work on the part of the guardian when detaching and assembling. In particular, the wagon frame is made to be foldable only when the storage basket is removed, so the storage basket cannot be used or stored. It did not eliminate the hassle of having to separate it every time.

Furthermore, when using a wagon for camping purposes, not only is the basic storage capacity itself somewhat insufficient, but the storage characteristics of various sizes and shapes, such as relatively long firewood or tent frames, cannot be considered. Depending on the configuration, it inevitably becomes more inefficient in terms of storage function.
