Abstract: A collapsible storage box structure includes a soft cloth box body and bottom plate, the opening of the box body provided with a frame, and two sides of the box body are respectively covered with a hard side plate; the bottom plate is made of hard material covered with soft cloth, a center of a bottom face of the soft cloth is in connection with a bottom of the box body in a straight line shape, upon use, the bottom plate is pressed downward to hold the storage box open, and while not in use, the bottom plate is pulled upward to allow the two side plates to be folded in a central portion of the storage box, and the two side plates and bottom plate are then folded and stacked together to form a flat body, thereby facilitating carrying and collecting.

Abstract: A modular drawer structure mainly includes a bottom board and front, rear boards and side boards coupled to the bottom board, where the boards each has an outer frame and a positioning frame configured on the inner edge of the outer frame, the outer frame is configured with buckling elements and engagement grooves, and a mesh sheet body constituted by interwoven net threads is configured on the positioning frame. Whereby, the front, rear boards and side boards are allowed to be positioned vertically on the peripheral of the bottom board by means of the mutual engagement of buckling element and engagement grooves of the outer frame of each board with each other in such a way to form a box-typed drawer. In addition, all the boards may be detached from each other and stacked together so as to facilitate handling and storage while not in use.

Abstract: A structure of expandable corrugated storage shelf system includes a support frame and coupling sleeves or retention plates, or coupling sleeves and retention plates, arranged at side surfaces of the support frame. The coupling sleeves each have an outer surface on which symmetrically arranged engagement slots are formed and convergent, through sloping, in a downward direction. The retention plates each have a curved configuration are convergent, through sloping, in the downward direction. To assemble, the coupling sleeves of a plurality of support frames are respectively fit to fixed rods to receive the retention plates of an adjacent one of the support frames to fit into the engagement slots of the coupling sleeves thereby connecting the plurality of support frames together in a side by side manner or forming a corner configuration and expansion of the storage shelf being made easy and being tidy and organized after being connected together.

Abstract: A storage shelf coupling sleeves each having symmetrically arranged engagement slots formed thereon to be convergent, through sloping, in a downward direction. The coupling sleeves are respectively mounted to fixed rods. A support frame has retention plates respectively fit to the coupling sleeves by being received in one of the engagement slots of each coupling sleeve. Another engagement slot of each of the coupling sleeves may receive a retention plate of another support frame to fit therein so that a number of support frames can be connected in a side-by-side manner thereby making assembly and expansion of the storage shelf easy and the expanded arrangement tidy and organized. The coupling sleeve is of a hollow cylindrical configuration. The support frame has corners each comprising one retention plate attached thereto. The retention plate is made convergent, through sloping, in the downward direction to facilitate fitting thereof into the coupling sleeve.

Abstract: A storage shelf includes a secure sleeve and a bracket that the secure sleeve is in a hollow cylinder shape with an outer circumference on which two symmetrical slots, constructed by L-shape elements, in a downward and skewed taper shape, are provided. A buckling piece, of a curve and in a downward and skewed taper shape, is provided at four corners of the bracket respectively. After assembling the multiply secure sleeves to a support tube, the buckling piece of the bracket is inserted into one slot of the secure sleeve so as to firmly position the bracket to the support tube for constituting a unity storage shelf. The other slot of the secure sleeve can be engaged by the buckling piece of the other bracket to extend multiply storage shelf in a parallel arrangement for achieving convenience for both assembly and extension in an orderly manner.
