Multifunctional storage box

Abstract

A multifunctional storage box includes a frame-like elementary unit composed of two horizontal boards and two vertical boards and a positioning piece fit to an end of the elementary unit. Each vertical board includes first and board segments that are connected to each other by a movable connection member. The elementary unit has an end forming a positioning structure, whereby the positioning piece is selectively fit to the positioning structure to form a box for receiving and storing various articles, or a number of such boxes can be stacked to form a piece of furniture, such as drawer, closet and desk. No tool is required and the assembling is easy and convenient. When not in use, the positioning piece is removed to allow the first and second board segments to be folded by means of the connection member into a flat configuration for easy carrying and storage.

1 . A multifunctional storage box, comprising an elementary unit comprising two horizontal boards and two vertical boards and a positioning piece fit to an end of the elementary unit, wherein each of the vertical boards comprises a first board segment and a second board segment, a movable connection member coupling between the first and second board segments, the elementary unit having an end forming a positioning structure to receive a positioning piece to fit thereto to form the multifunctional storage box, which is adapted to receive and store various article, or is stackable in multiplicity to form a piece of furniture, such as drawer, closet, and desk, or allows the positioning piece to be removed and the first and second board segments be folded by means of the movable connection member into a flat configuration for easy carrying and storage. 
     
     
         2 . The multifunctional storage box according to  claim 1 , wherein connection member coupling between the first board segment and the second board segment of the vertical board comprises a hinge. 
     
     
         3 . The multifunctional storage box according to  claim 1 , wherein the positioning structure comprises a notch formed in an end of one horizontal board, a slide slot formed in and vertically extending along an inside surface of each of the vertical boards at a location corresponding to the notch, and mounting holes corresponding to the notch, the positioning piece having a top edge forming a flat flange substantially aligning the notch, the flat flange forming through holes corresponding to the mounting holes, whereby with the positioning piece being received and vertically sliding down along the slide slots, pins are received through the through holes and fit into the mounting holes to secure the positioning piece in position. 
     
     
         4 . The multifunctional storage box according to  claim 1 , wherein the positioning structure comprises steps formed at ends of the horizontal boards and the vertical boards and symmetrically arranged fitting grooves formed in the steps to receive a flat board like positioning piece to be first positioned on the steps and then receive retention pieces to fit into the fitting grooves for holding corners of the positioning piece and thereby retaining the positioning piece in position.
