Multifunctional case and use thereof

Abstract

A multifunctional case includes a case body and a case lid configured to cover the case body. The case body is detachably connected to the case lid, and an end surface of the case lid defines a panel. A pair of foldable supporting frames are pivotally connected to the case lid. When the pair of foldable supporting frames are in an unfolded state, the pair of foldable supporting frames support the case lid to define a table. When the pair of foldable supporting frames are in a folded state, the pair of foldable supporting frames are folded to be stored in the case lid.

What is claimed is:

 a case body, and   a case lid configured to cover the case body, wherein:
 the case body is detachably connected to the case lid, 
 an end surface of the case lid defines a panel, 
 a pair of foldable supporting frames are pivotally connected to the case lid, 
 when the pair of foldable supporting frames are in an unfolded state, the pair of foldable supporting frames support the case lid to define a table, and 
 when the pair of foldable supporting frames are in a folded state, the pair of foldable supporting frames are folded to be stored in the case lid. 
   
     
     
         2 . The multifunctional case according to  claim 1 , wherein:
 the case lid comprises two lid sides opposite to each other,   each of the two lid sides comprises two pivoting points,   each of the two lid sides comprises two position-limiting protrusions disposed between the two pivoting points,   pivoting ends of each foldable supporting frame of the pair of foldable supporting frames are bent to form position-limiting members which are arc-shaped or zigzag-shaped,   distal ends of the position-limiting members are pivotally connected to the two pivoting points of the two lid sides, and   the two position-limiting protrusions abut the position-limiting members when the pair of foldable supporting frames are unfolded, so that the pair of foldable supporting frames are inhibited from rotating outward.   
     
     
         3 . The multifunctional case according to  claim 2 , wherein:
 each foldable supporting frame of the pair of foldable supporting frames comprises two supporting arms parallel to each other and a connecting arm,   first ends of the two supporting arms define the pivoting ends, and   the connecting arm is connected to second ends of the two supporting arms relative to the pivoting ends.   
     
     
         4 . The multifunctional case according to  claim 3 , wherein:
 one of the two pivoting points on a first one of the two lid sides and one of the two pivoting points on a second one of the two lid sides that are disposed on a same side of the case body are respectively connected to the pivoting ends of a corresponding one of the pair of foldable supporting frames.   
     
     
         5 . The multifunctional case according to  claim 1 , wherein:
 the pair of foldable supporting frames are made of metal tubes.   
     
     
         6 . The multifunctional case according to  claim 1 , wherein:
 the case body comprises a pulling rod and two rollers,   the pulling rod is fixedly connected to a rear surface of the case body, and   the two rollers are rotatably connected to a rear of two sides of the case body.   
     
     
         7 . The multifunctional case according to  claim 6 , wherein:
 the case body comprises one or more position-stopping protrusions disposed on a lower surface of the case body, and   a height of the one or more position-stopping protrusions is equal to a height between a lowermost edge of the two rollers and the lower surface of the case body.   
     
     
         8 . The multifunctional case according to  claim 1 , wherein:
 two outer side walls of the case body opposite to each other are pivotally disposed with two buckles, and   the case lid comprises two buckling grooves corresponding to positions of the two buckles and configured to be buckled to the two buckles.   
     
     
         9 . A use of the multifunctional case according to  claim 1  for a camping case, a suitcase, or a packing case. 
     
     
         10 . The multifunctional case according to  claim 2 , wherein:
 the pair of foldable supporting frames are made of metal tubes.   
     
     
         11 . The multifunctional case according to  claim 3 , wherein:
 the pair of foldable supporting frames are made of metal tubes.   
     
     
         12 . The multifunctional case according to  claim 4 , wherein:
 the pair of foldable supporting frames are made of metal tubes.
