Folding table

Abstract

We offer a folding table that can be quickly put away when not in use. [Solution] The table comprises a first top plate section 2 and a second top plate section 3 that can rotate between a folded state and an unfolded state around a rotational axis L, and a first leg section 4 and a second leg section 5 that are provided on the lower surfaces of the first top plate section 2 and the second top plate section 3 so as to be able to rise and fall. The first leg section 4 and the second leg section 5 have a first leg rotational axis 40 and a second leg rotational axis 50 that are along the lower surfaces of the first top plate section 2 and the second top plate section 3 and form a first acute angle and a second acute angle with respect to the rotational axis L, and a first undulating section 41 and a second undulating section 51 that rise and fall in line with the rotational axis L as the first leg section 4 and the second leg section 5 rotate. The first leg connecting section 6 rotatably connects the first undulating section 41 and the second undulating section 51, so that when the first top plate section 2 and the second top plate section 3 rotate, the first undulating section 41 and the second undulating section 51 maintain the same angle with respect to the rotational axis L.
