Description

Multi-Purpose Wagon

The present invention relates to a multi-purpose wagon, and more particularly, to a multi-purpose wagon capable of expanding space.

Parents with more than one child buy a lot of wagons for convenience because the more children they have, the more luggage they have to take when they go out. In particular, in the season when families often go out to play, parents prefer wagons because parents have to pack not only their children's luggage but also their children's luggage.

However, when carrying a lot of luggage with several children on the wagon, the children's boarding space is often narrow, or the child cannot board the wagon due to lack of space.

In the existing wagon, it was difficult to secure additional space other than the designated space, so it was difficult to increase luggage or to carry more children. So, there was the inconvenience of parents carrying luggage or needing an additional wagon.
