Description

Folding Wagon {FOLDING WAGON}

The present invention relates to a wagon, and more particularly, to a foldable wagon capable of reducing the overall volume and increasing efficiency during loading, moving and storage by folding the body, ceiling and handle parts of the wagon.

Compared to a stroller, it has ample storage space and has the advantage of being able to go out with two or three infants by a guardian alone. As the demand increases, various types of wagons for infants are being released.

However, the existing baby wagon has a problem in that it is difficult to store because it is bulky, and to solve this problem, a foldable baby wagon is being developed.

As an example, Korean Patent Registration No. 10-2095838 (2020.03.26) discloses a floor frame and a floor frame by pushing the connection bracket of the floor frame upward by a rotating frame connected to a pusher frame provided with a handle to fold the wagon. Disclosed is a wagon for infants that can reduce storage space and storage space by making the seat frame connected to the pole to be folded, and by making the wagon easy to fold while thinning the folded thickness when folded.

In addition, Korean Patent Registration No. 10-2012369 (2019.08.13) has a structure that extends the length of the seat part and the floor frame supporting the seat part from the bottom in response to the number of infants on board, so that the overall length is increased. Disclosed is a wagon for infants that can be adjusted so that it is easy to control while driving and can adjust the distance between the current wheel and the rear wheel when the wagon is folded.
