Storage box
A storage box includes alternately arranged latch structures and protrusions disposed on an end of a side panel, latch holes, and recessions corresponding to the latch structures and protrusions disposed on the other end of the side panel, such that four side panels are coupled to form a frame. The bottom of each side panel includes a limit groove such that four sides of a bottom board are fixed into these limit grooves to serve as the bottom of the storage box. If the storage boxes are arranged side by side with each other, the protrusion on a fixture is latched into a connecting section, so as to fix the corresponding positions of the side-by-side storage boxes. The side-by-side boxes are fixed with each other by inserting a hook structure separately disposed on both sides of a limit component into a groove disposed at the top of each side panel.
The present invention relates to a storage box, and more particularly to a storage box structure comprised of a plurality of components, such that a plurality of storage boxes can be fixed together with each other.
BACKGROUND OF THE INVENTIONIn general, most storage boxes are fixed storage boxes. In other words, the storage box has a fixed volume after it is manufactured and its volume cannot be reduced by folding the storage box. The advantages of such fixed storage box include its strong strength and heavy-duty characteristic. However, the fixed storage box has a drawback that its volume cannot be reduced when it is not in use. For storage and transportation, the volume of such storage box occupies too much space.
Therefore, some storage boxes are designed as foldable one. For example, the storage box is made of soft cloth, and hard rod components are installed separately at each edge of the storage box, so that the soft box can be supported by the rod components to define a storage box. If the storage box is not in use, then the storage box made of the soft cloth can be folded into a small volume and the rod components can be taken apart. However, such soft foldable storage box has a drawback of its poor strength. If users want to stack several storage boxes in order to save storage space, then the connection between the rod components may be difficult (or even impossible), and the strength of the storage boxes becomes much fragile than a standalone storage box.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to overcome the shortcomings of the prior art fixed storage box that cannot reduce its volume for storage or transportation and wastes much space. The invention also improves the insufficient strength of the prior art storage box.
The second objective of the present invention is to overcome the shortcomings of the prior art that is inconvenient to stack several storage boxes to form a larger cabinet, and the storage boxes cannot be fixed or stacked.
A storage box of the present invention comprises four identical side panels, and each side panel includes alternately arranged latch structures and protrusions disposed on one side of the side panel, and latch holes and recessions corresponding to the latch structures and protrusions disposed on the other end of the side panel. The four side panels are fixed to each other to form a frame, and a limit groove is disposed on an internal side of the bottom of each side panel, such that the four sides of a bottom board can be fixed to the limit grooves to serve as the bottom of the storage box. A folding line structure is disposed at the middle of the bottom board, so that the bottom board can be folded into halves. If the storage box is not in use, the bottom board can be folded along the folding line structure to reduce the volume for storage or transformation. Since each side panel is an independent component, therefore the present invention can improve the shortcomings of the prior art fixed storage box that has a fixed volume and wastes too much space. The latch structures and protrusions are used to connect with the corresponding latch holes and recessions, such that the side panels can be securely fixed with each other. Therefore, the storage box of the present invention not only can be separated, but also can have a strong strength after they are assembled.
If the storage boxes are arranged side by side, the protrusion of a fixture can be latched into a connecting section at the bottom side of the side panel so as to fix the corresponding positions of the side-by-side storage boxes. A hook structure separately disposed on both sides of a limit component is hooked into a groove at the top side of the side panel, such that two side-by-side storage boxes will not be separated from each other. Therefore, users can stack several storage boxes transversally into a large and secure cabinet. By the fixture of different shapes, the cabinet can be formed in different combinations.
BRIEF DESCRIPTION OF THE DRAWINGS
The technical contents of the present invention will now be described in more detail hereinafter with reference to the accompanying drawings that show various embodiments of the invention.
Refer to
Further, one of the other two edges of the side panel 11 is a bottom edge 12 and a limit groove 121 is disposed at an internal side of the bottom edge 12, and a bottom board 20 has a folding line structure 201 at its middle (as shown in
Further, the storage box 10 includes a top side 13 disposed at an edge corresponding to the bottom side 12 and a handle section 131 disposed proximate to the middle of the top side 13, such that users can move the storage box 10 easily by using the handle section 131.

While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
Claims
1. A storage box, comprising:
- four identical side panels, each having alternatively arranged latch structures and protrusions disposed on an edge of the side panel, and latch holes and recessions disposed on the other end of the side panel and corresponding to the latch structure and the protrusions, such that the four side panels are coupled to form a frame, and a bottom side being disposed on an end of both edges of the side panel and a limit groove being disposed at an internal side of the bottom side;
- a bottom board, including four sides to correspond with the limit grooves for being inserted into and fixed to the limit grooves; and
- a folding line structure, disposed at the middle of the bottom board for folding the bottom board.
2. The storage box of claim 1, wherein the bottom side includes a top side disposed at a corresponding side and a handle section disposed proximate to the top side.
3. The storage box of claim 1, wherein the bottom side includes a groove disposed at an internal side of the top side corresponding to the bottom side, such that when the storage boxes are arranged side by side with each other, the latch structure disposed separately on both sides of a fixture is latched into two grooves to limit the corresponding position of the side-by-side storage boxes.
