Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of CD storage structure, in particular, a modular design, which can be folded and occupy no space when not in use, and a type of expandable modular which can extend the CD storage place by insertion when used. It relates to a CD storage box.

[0002]

[Prior art]

 Existing CDs can store large amounts of data digitally, so they are widely used instead of records that are well known in the music world, and are used for storing software. As CD usage has increased, various types of CD storage structures have been provided for storing and storing CDs. Among them, most of the well-known CD storage stands have multiple partitions on a simple frame. Most of these products have a fixed appearance, so they cannot be folded when not in use or transported, take up space, and can be displayed in accordance with the furniture. There were few things and there was no change or scalability in its display and storage functions. In addition, various types of CD stand that combine many pieces are widely used, but their appearance, use effects, and practical functions are different, and each has its own advantages and disadvantages. In fact, it is actually difficult to compare each one, but as a whole it has not been complete yet.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to provide an expandable modular CD storage box which can be arbitrarily expanded to expand a CD storage space without taking up a space for folding storage.

A locking hole 14 is provided, and a pair of male and female locking edges are provided on the front end face and the rear end face of the bottom piece 10. When the two side pieces 20 are merged, the size is almost the same as that of the bottom piece 10. At the corresponding positions of the two side pieces 20 and the bottom piece 10, a convex pillar 22 and a locking edge 23 are provided. The convex pillar 22 can be inserted into the connecting hole 13, and the two side pieces 20 can be folded when not in use. Occupy space, and lock male and female around the bottom piece 10 when using There are CD left space and prolongation possible by being engaged with each other, that have a extensible modular CD storage box having the above configuration.

According to a second aspect of the present invention, the partitioning pieces 11 of the bottom piece 10 are formed in a strip shape and protruded from the middle surface of the bottom piece 10 so as to be arranged in parallel, the two side pieces 20 have an L shape, The partition piece 21 is provided upward from the vertical end of the bottom of the side piece 20, and the upward length thereof is provided so as to supplement the remaining length when the partition piece 11 is formed on the surface of the bottom piece 10. A scalable modular CD storage box according to claim 1, characterized in that:

According to a third aspect of the present invention, the bottom piece 10 has an inverted U shape, and two or more dovetail-shaped locking grooves are provided on the front end face thereof, and two locking grooves are provided on the rear end face at positions corresponding to the locking grooves. The expansion according to claim 1 or 2, wherein the dovetail-shaped locking projection is provided, and a cutout is provided in the middle of the locking projection to provide elastic clamping force during use. A modular CD storage box is available.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIGS. 1 and 2, each module unit of a CD storage box 1 of the present invention is composed of a bottom piece 10 and two side pieces 20.

The bottom piece 10 is an inverted U-shaped piece, and a plurality of parallel partition pieces 11 are provided on the inner surface of the bottom piece 10. A connecting arm 12 is provided on each of the right and left sides of the front end and the rear end of the bottom piece 10, and a stop edge 17 is provided on the inside of the connecting arm 12 and a connecting portion of the bottom piece 10. The bottom piece 10 is provided with a pair of male and female locking edges at the front end and the rear end of the bottom piece 10. The male and female locking edges are formed at the front end wall. It includes two dovetail-shaped locking grooves 15 provided on the upper side and two dovetail-shaped locking protrusions 16 provided at corresponding positions on the rear end wall, and the locking protrusions 16 are easily resilient by their elasticity. It can be combined and locked.

[0010] Each of the two is a half-piece having an L-shape, and when they are merged, they are almost the same size as the bottom piece 10, and each one piece is extended above the bottom of the vertical end to form a pair. A partition piece 21 provided so as to face the bottom piece 10, the length of which is provided to replenish the portion remaining when the partition piece 11 is formed on the bottom piece 10, and the outer lower portion of each side piece 20. Are provided, and the convex pillars 23 are inserted into the connecting holes 13 described above.

As a result, at the time of assembling, the protruding columns 22 of the two side pieces 20 are placed in the connecting holes 13 of the bottom piece 10, and the side pieces 20 are easily introduced into the bottom piece 10 by the design of the guide grooves for assembling. Can be

As shown in FIGS. 1 and 3, when the CD storage box 1 according to the present invention is not used, both side pieces 20 can be folded and overlapped on the bottom piece 10 to form a flat shape. By locking the locking holes 14 with each other, it is possible to prevent the detachment. Therefore, it is convenient to store and save the space, and when the two side pieces 20 are folded upwards during use, when the two side pieces 20 are folded to an appropriate position, The two side pieces 20 are positioned so as not to fall outside, and are separated by partitioning pieces 21 and 11 installed corresponding to the side piece 20 and the bottom piece 10. A certain number of CDs can be left in the space.

As shown in FIGS. 4 and 5, the present invention has a modular design that can be expanded as needed, and therefore can be expanded in any combination in use, and the CD storage box originally placed When the CD storage capacity of the first CD storage box 1 is filled, the locking projection 16 of the other CD storage box 1 is inserted into the locking groove 15 of the original CD storage box 1 to double the CD storage space. Is very convenient and has a remarkable inventive step and practicality in use.

[0014]

[Effect of the invention]

 The structure of the present invention is simple, foldable and takes up little space, and it can be inserted into each other to expand the CD storage space, providing special effects and economic advantages that were not achieved with ordinary CD stands. Can be provided.
