Abstract
A folding/unfolding mechanism includes first, second and third coupling pieces. Each of the first and second coupling pieces is configured to be fixed at an end of a bar and includes a hole and a slot with a closed bottom and an open top. The third coupling piece includes a slot with closed bottom and top. A first rod passes through the holes of the first and second coupling pieces and the slot of the third coupling piece. A second rod is integrally formed or coupled with a top portion of the third coupling piece, and movable together with the third coupling piece. The second rod is selectively inserted into the slots of the first and second coupling pieces, thereby selectively restricting the rotation of the first and second coupling pieces with respect to each other.
