Abstract

The present invention is a folding case comprising a first connecting piece assembling a base plate with a front and post sided plate, and a second connecting pieces assembling the base plate with a left and right sided plate, further, assembling four corner connecting pieces with corresponding inserting apertures, thus assembling a firm case structure. When the corner connecting pieces are not inserted into the inserting apertures, the front and post sided, the left and right sided and the base plate can fold overlapping each other for easier storage.

Description

BACKGROUND OF THE INVENTION

(a) Field of Invention
The present invention relates to a case shaped structure, e.g. storage case, drawer etc. to provide a folding case with a structural firmness and convenient storage.
(b) Description of the Prior Art
In everyday life, storage cases are often needed for collecting and storing items; moreover, venders use storage cases to store goods on sale, e.g. vegetables, fry goods etc. for preserving or categorizing goods.
The conventional storage case that allows an acceptable amount of storage usually inherits an invariable size, thus different staking cases appeared, allowing the user to stack the vacant storage cases away.
Although such a stacking method allows the stacking of a number of vacant storage cases, but in a conventional home, a number of vacant storage cases may not be applicable; in addition, the living area is originally limited, thus vacant storage cases can cause obstruction on space.
Thus the inconvenience is not in the number of cases, but the set size of the conventional vacant storage case.

SUMMARY OF INVENTION

A primary objective of the present invention is to provide four corners of a base plate with a first and second connecting piece assembled thereon, whereby the first connecting piece connects the base plate with a front and post sided plate, and the second connecting piece connects the base plate with the left and right sided plate, allowing folding between the front and post sided, the left and right sided and the base plate.
Furthermore, inserting apertures are formed on upper tips of the front, post, left and right sided plates, whereby four corner connecting pieces are inserted into the corresponding inserting apertures, thus assembling a firm case structure.
When the corner connecting pieces are not inserted into the inserting apertures, the front and post sided, the left and right sided and the base plate can fold overlapping each other for easier storage.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

To better understand the present invention, detailed descriptions shall be given with the accompany drawings hereunder.
As shown if FIG. 1, a folding box comprising of a base plate 11, a front and a post sided plate 12 and a left and a right sided plate 13. A frame structure of the front and post sided plate 12 as well as the left and right sided plate 13 comprises a circular tube-shaped frame with four sides, whereby applying a knitted material 15, e.g. cloth, rattan etc. to the frame thereafter. An opening 16 can be formed on a plate body of the left and right sided plate 13 (or the front and post sided plate 12) for convenient carriage, but the folding case can also be utilized as a drawer.
As shown in FIG. 2, four first connecting pieces 21 and four second connecting pieces 22 are assembled to four corners of the base plate 11, wherein the front and post sided plate 12 having the first four connecting pieces 21 connects to the base plate 11 whereas the left and right sided plate 13 having the second connecting pieces 22 connects to the base plate 11, thus allowing the front, post, left and right sided plates 12, 13 and the base plate 11 to inherit folding capabilities respectively.
Furthermore, a inserting aperture 14 is formed on two top-most corners of the two front and post sided plates 12 and the two left and right sided plates 13, wherein four corner connecting pieces 23 are inserted into the corresponding inserting apertures 14, thus allowing the front and post sided plate 12, the left and right sided plate 13 and the base plate 11 to fold overlapping each other for easier storage.
Two inserting apertures 14 are formed on each corner of the base plate 11, provided for inserting the first connecting piece 21 and the second connecting piece 22 respectively. The inserting aperture 14 is formed on each corner of the two front and post sided plates 12, provided for inserting the first connecting piece 21; the inserting aperture 14 is also formed on each corner of the two left and right sided plates 13, provided for inserting the second connecting piece 22. The aforesaid inserting apertures 14 can be formed directly by a hollow structure of circular tube shape of the balk frame.
As shown in FIGS. 2 and 3, the first connecting piece 21 comprises of a base portion 24, with an pivoting rod 25 and a inserting rod 26 forming on the base portion 24, wherein the inserting aperture 14 of the base plate, having the pivoting rod 25 inserted thereinto and the inserting aperture 14 of the front and post sided plate 12 having the inserting rod 26 inserted thereinto, thereby enabling the front and post sided plate 12 to use the pivoting rod 25 as the center axis for folding purposes. Whereas, the structure of the second connecting piece 22, as shown in FIGS. 5 and 6, a base portion 24 is formed, with two pivoting rods 25 forming parallel on the base portion 24, wherein the inserting aperture 14 of the corresponding base plate 11 and the left and right sided plate 13 having the pivoting rods 25 inserted thereinto, further, the left and right sided plate 13 uses the pivoting rod 25 as the center axis for folding purposes.
Therefore, the front and post sided plates 12, the left and right sided plates 13 and the base plate 11 of the whole folding case enables folding into a case shape and securing the case shape by means of the corner connecting pieces 23, thus achieving a firm storage case, moreover, as shown in FIGS. 7 and 8, the corner connect pieces 23 comprises of a base portion 24, with two parallel inserting rods 26 forming on the base portion 24, wherein neighboring inserting apertures 14 of the front and post sided plate 12 and the left and right sided plate 13 having inserting rods 26 inserted.
As shown in FIGS. 3, 5 and 7, the first connecting piece 21, the second connecting piece 22 and the corner connecting piece 23 are molded as one unit. The components on the base portion 24, e.g. pivoting rod 25, inserting rod 26 etc. can be manufactured separately, and assembled together firmly by means of screws, to achieve the same effect.
In conclusion, the aforesaid invention is a better folding case structure.
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
