Rotation support member for front panel/rear panel of foldable container

Abstract

The present disclosure provides a rotation support member for supporting a rotation operation of a front panel and a rear panel in a container including the front panel and the rear panel rotatably coupled to a bottom plate, and third and fourth torsion bars serving as reference axes of rotation for the front panel and the rear panel, in which the rotation support member includes: a first rotation support member including one end fixedly coupled to a post coupling point ( 220 ) of the front panel which is spaced apart by a predetermined distance from a lower end of the front panel, and the other end positioned at a bottom plate coupling point ( 210 ) positioned on a side spaced apart by a predetermined distance from a front end of the bottom plate; and a first rotation support member including one end fixedly coupled to a post coupling point ( 220 ) of the rear panel which is spaced apart by a predetermined distance from the lower end of the rear panel, and the other end positioned at a bottom plate coupling point ( 210 ) positioned on a side spaced apart by a predetermined distance from a rear end of the bottom plate, in which the other end of the first rotation support member is coupled to the third torsion bar at the bottom plate coupling point ( 210 ) such that the front panel is rotated with respect to the third torsion bar, and the other end of the second rotation support member is coupled to the fourth torsion bar at the bottom plate coupling point ( 210 ) such that the rear panel is rotated with respect to the fourth torsion bar.

What is claimed is: 
     
         1 . A rotation support member for supporting a rotation operation of a front panel and a rear panel in a container comprising the front panel and the rear panel rotatably coupled to a bottom plate, and third and fourth torsion bars serving as reference axes of rotation for the front panel and the rear panel, wherein the rotation support member comprises:
 a first rotation support member including one end fixedly coupled to a post coupling point ( 220 ) of the front panel which is spaced apart by a predetermined distance from a lower end of the front panel, and the other end positioned at a bottom plate coupling point ( 210 ) positioned on a side spaced apart by a predetermined distance from a front end of the bottom plate; and   a second rotation support member including one end fixedly coupled to a post coupling point ( 220 ) of the rear panel which is spaced apart by a predetermined distance from the lower end of the rear panel, and the other end positioned at a bottom plate coupling point ( 210 ) positioned on a side spaced apart by a predetermined distance from a rear end of the bottom plate, wherein   the other end of the first rotation support member is coupled to the third torsion bar at the bottom plate coupling point ( 210 ) such that the front panel is rotated with respect to the third torsion bar, and   the other end of the second rotation support member is coupled to the fourth torsion bar at the bottom plate coupling point ( 210 ) such that the rear panel is rotated with respect to the fourth torsion bar.   
     
     
         2 . The rotation support member according to  claim 1 , wherein the first rotation support member is coupled to and rotated integrally with the front panel at the post coupling point, and
 the second rotation support member is coupled to and rotated integrally with the rear panel at the post coupling point.   
     
     
         3 . The rotation support member according to  claim 1 , wherein the first rotation support member has an L-shape including a parallel member ( 200   a ) parallel to a ground and a vertical member ( 200   b ) perpendicular to the ground when the front panel is in a stand-up state, and
 the second rotation support member has an L-shape including a parallel member ( 200   a ) parallel to a ground and a vertical member ( 200   b ) perpendicular to the ground when the rear panel is in a stand-up state.   
     
     
         4 . The rotation support member according to  claim 3 , wherein the parallel member has a length (L) such that a height of the container in a folded state is ¼ of a height of the container in an unfolded state.
