WIPO Patent Application WO/2017/179774

A1

A collapsible container having a degree of freedom-constraining vertical guide bar, according to the present invention, comprises: a lower panel (110); an upper panel (120) disposed on the upper part of the lower panel (110) so as to be spaced apart therefrom; a pair of side-wall panels (130) installed between the lower panel (110) and the upper panel (120) on both sides; door panels (140) which are vertically mounted on the front and rear of the upper panel (120) and which may be opened in order to load and unload cargo inside; guide bars (150) coupled to the edges of both side parts of the door panels (140); and corner casters (160) disposed on the upper panel (120) and coupled so as to slidingly move along the guide bars (150), wherein, when the corner casters (160) vertically move along the guide bars (150), the degrees of freedom of the pair of side-wall panels (130) are constrained, thereby enabling the pair of side-wall panels (130) to be collapsed or expanded by a same angle, and thus enabling the collapsing operation to be undergone in a regular way.
