Folding table with crossed legs

Abstract

A folding table with crossed legs is provided. The table comprises a tabletop board, first leg shelf and second leg shelf. The two leg shelves support the tabletop board under the tabletop board. The two leg shelves also cross and pivot with each other at their central locations. The top of the first leg shelf is pivoted on the one side of the undersurface of the tabletop board. A fastening device is fixed on the other side of the undersurface of the tabletop board. A transverse supporting rod is fixed on the top of the second leg shelf. The transverse supporting rod is fastened on the undersurface of the tabletop board by the fastening device. The top of the second leg shelf is not directly fixed on the undersurface of the tabletop board. When the table is unfolded, the undersurface of the tabletop board and the transverse supporting rod are fixed oppositely by the fastening device. When the table is folded, the transverse supporting rod is disengaged from the fastening device.
