Foldable container including torsion bar module for collapsing side panel

Abstract

The present disclosure relates to a foldable container including a torsion bar module, including: first hinges (310) provided at both outermost ends of the torsion bar module; a plurality of torsion bars arranged between the first hinges; and a second hinge (320) and a third hinge (330) inside the first hinges, with which both ends of the torsion bars are coupled and arranged. The second hinge (320) includes a second torsion bar mounting member (321) and a second support member (323), wherein the second torsion bar mounting member (321) receives the torsion bars to be inserted and mounted therein from both sides and is coupled to the bottom plate, and the second support member (323) receives the second torsion bar mounting member (321) to be relatively rotatably coupled thereto and is coupled to the side panel, and the third hinge (330) includes a third torsion bar mounting member (331) and a third support member (333), wherein the third torsion bar mounting member (331) receives the torsion bars to be inserted and mounted therein from both sides and is coupled to the side panel, and the third support member (333) receives the third torsion bar mounting member (331) to be relatively rotatably coupled thereto and is coupled to the bottom plate.

1 . A foldable container equipped with a torsion bar module for folding a side panel, the container comprising: a bottom plate; a top plate; side wall panels including a front panel, a rear panel, and a side panel provided between the bottom plate and the top plate, and a torsion bar module (TM) provided at a lower end to rotate the side panel, wherein the top plate is completely detachably coupled to the side wall panel,
 the torsion bar module comprising:   first hinges ( 310 ) provided at both outermost ends of the torsion bar module;   a plurality of torsion bars arranged between the first hinges; and   a second hinge ( 320 ) and a third hinge ( 330 ) inside the first hinges, with which both ends of the torsion bars are coupled and arranged, wherein   the second hinge ( 320 ) includes a second torsion bar mounting member ( 321 ) and a second support member ( 323 ), wherein the second torsion bar mounting member ( 321 ) receives the torsion bars to be inserted and mounted therein from both sides and is coupled to the bottom plate, and the second support member ( 323 ) receives the second torsion bar mounting member ( 321 ) to be relatively rotatably coupled thereto and is coupled to the side panel, and   the third hinge ( 330 ) includes a third torsion bar mounting member ( 331 ) and a third support member ( 333 ), wherein the third torsion bar mounting member ( 331 ) receives the torsion bars to be inserted and mounted therein from both sides and is coupled to the side panel, and the third support member ( 333 ), receives the third torsion bar mounting member ( 331 ) to be relatively rotatably coupled thereto and is coupled to the bottom plate.   
     
     
         2 . The foldable container according to  claim 1 , further comprising:
 a second upper connecting member ( 322 ) that couples the second support member ( 323 ) of the second hinge to the side panel; and   a second lower connecting member ( 324 ) that couples the second torsion bar mounting member ( 321 ) of the second hinge to the bottom plate, wherein   the second upper connecting member ( 322 ) is rotated together with the side panel rotated in a folding process, and the second lower connecting member ( 324 ) is coupled to the bottom plate and not rotated in the folding process.   
     
     
         3 . The foldable container according to  claim 1 , further comprising:
 a third lower connecting member ( 334 ) that couples the third support member ( 333 ) of the third hinge to the bottom plate; and   a third upper connecting member ( 332 ) that couples the third torsion bar mounting member ( 331 ) of the third hinge to the side panel, wherein   the third upper connecting member ( 332 ) is rotated together with the side panel rotated in a folding process, and the third lower connecting member ( 334 ) is coupled to the bottom plate and not rotated in the folding process.   
     
     
         4 . The foldable container according to  claim 1 , wherein the plurality of torsion bars are arranged in a line on a same axis between the first hinges at the both outermost ends. 
     
     
         5 . The foldable container according to  claim 4 , wherein four of the torsion bars are arranged between the first hinges at the both outermost ends. 
     
     
         6 . The foldable container according to  claim 1 , wherein the second hinge and the third hinge are inside the first hinge and alternately arranged.
