Abstract

PROBLEM TO BE SOLVED: To solve a trouble for achieving stability in upright position of racks and saving a space at the same time upon accommodation in filing racks at high positions. SOLUTION: A staircase is formed by drawer parts with double structures whose front parts rotate by 90 deg. and a lowermost stage which can be drawn in two stages. Thus, a multifunctional filing rack can be formed in which materials accommodated at high positions can be easily taken out and rack boxes having several kinds of functions are combined together.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing, office or classroom, etc., in which books or small articles can be stored close to the ceiling and books or small articles can be easily taken out at high places in order to obtain a space-saving effect. Drawer with storage and staircase function to enhance the storage effect of books and small items, and front and rear double-sided structure and front row side rotation for taking out books or small items on the back row side Regarding the structure.

[0002]

2. Description of the Related Art A conventional storage shelf for books or small articles has a small depth, requires a large wall for placing, is easy to fall down, and uses a stepladder or a ladder to take out stored items at a high place.

In a conventional book shelf for books or small articles, books or small articles are arranged side by side in a row and arranged in several levels. In this case, there is a limit to the storage of books or small items, and when installing shelves up to a high position, there is a risk of falling to the front, which limits the height and inconvenience of occupying a large area of the wall. There was sex. In addition, in order to take out high-level storage items for general storage shelves,
Separate preparation of a stepladder, ladder, etc. was necessary.

[0004] The present invention has a built-in staircase mechanism to increase the depth of the storage shelf, secure uprightness, increase storage efficiency, and facilitate removal of stored items from high places, and is convenient for removing stored items from high places. To offer

[0005]

The main point of the present invention is to increase the depth of the bookshelf to at least twice so as to prevent the bookshelf from falling to the front and to increase the efficiency of storing books or small articles. It has a staircase storage part at the bottom that becomes a convenient staircase for taking out books or accessories from high places, and has a mechanism to increase the storage space by making the storage of books or accessories a double structure in front and back, and a double front and back When taking out books or small articles stored in the rear part of the structure, the front storage part is pulled out, and this part is configured to be rotatable by 90 degrees to facilitate taking out. According to the present invention, the following effects can be expected. (1) The shelf can be divided into several stages, the storage method can be changed depending on the item, and the shelf can be used as an efficient organizing shelf. (2) It is easy to take out and store stored items at a high place. (3) The storage capacity of books or small articles is increased by adopting the double structure, and the book or small articles stored in the rear part can be easily taken out by rotating the front part of the double structure by 90 degrees.

FIG. 1 shows an example of a bookshelf according to the present invention.
The top floor (A) is a three-tiered shelf with an opening / closing door, and the second tier (B) is a double-structured shelf, which is of a drawer type, and the front part is 9
It is easy to take out books or small articles stored in the rear part by rotating them 0 degrees. The third row (C) is a drawer-type shelf with a door, which has a structure capable of storing large items. The fourth and fifth tiers (D) and (E) are storage units having a double structure in which books or small articles are taken out from above after being pulled out because they are at a low position. The sixth tier (F) houses the seventh tier (G) and the eighth tier (H) with casters, and has a door (I). (G) accommodates (H) in the eighth row (F)
(G) and (H) are connected by a metal rail, and further restrict excessive movement by a stopper.

FIG. 2B shows a mechanism in which the front part rotates on the bottom plate as shown in the figure. Half of the depth is pulled out and the front turns 90 degrees. The rear book or accessory can thus be easily removed. (C) is a storage portion for large books or small articles. Half the depth as in the second stage
Is pulled out, and the front part rotates 90 degrees like the second stage.
(D) and (E) show the drawer portions of the fourth and fifth stages. This part is designed to take out a book or accessory from above just by pulling it out.

(F) is an accommodating portion of the drawer-type staircase portion. It has a metal rail and a stopper on the inside, so that the second step of (G) can be moved. (G) The drawer section (H) has a travel range defined by metal rails and pulleys, and allows smooth travel. At the bottom of the stair formation part, two sets of four casters shown in FIG. 1 are installed to distinguish the operation of the lowermost step from the operation of the second step, and a stopper is installed to regulate the traveling range to secure safety. I have. As described above, this arrangement shelf has a multifunctional structure while maintaining the upright stability, and can be used in a wider range.
