Check out this cool concept by Taiwanese designers, A Wheel Umbrella that you can drag it along the road lazily.
I guess no adult would like to drag it along the road like the picture above. So I assume the concept is made for Kids only. Perhaps for kids, such kind of umbrella is too heavy. So they are allow to drag it along the way like dragging a travel bag with wheel. Pretty cool, and it has smiley, too!
