Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable shelf having a humidity control function.

1 m The paper used for books expands and contracts in response to changes in humidity, and its strength also changes significantly. If this happens over a long period of time, deterioration is inevitable.

In addition, in order to preserve books, scrolls, paintings, etc. stored on shelves so that their quality does not deteriorate over a long period of time, conventionally,
In the space where these items were stored, a humidity control agent such as silica gel or alumina glue was placed in a perforated bag, and this humidity control agent was used to maintain the humidity at a substantially constant level.

However, since the humidity control agent placed in a perforated bag has a small surface area and it is difficult to place it close to each stored item, its humidity control function is poor in a short period of time. Further, since a space is required to place the storage object, the storage space becomes narrow, and this often becomes an obstacle when taking out and taking out the storage object.

Particularly in the case of movable shelves that try to make effective use of a narrow space, a decrease in storage efficiency will significantly diminish the features of the movable shelves.

The present invention relates to an improvement of a movable shelf that overcomes such difficulties, and the present invention relates to an improvement of a movable shelf that overcomes the above-mentioned difficulties, and in which powder having moisture absorption and desorption ability is applied to the movable shelf where the shelf front surfaces of each movable unit shelf are in contact with each other during convergence. The present invention is characterized in that a paper core made of strained humidity control paper is attached to the inner surface of the shelf exposed to the shelf space of the movable shelf.

In the present invention, in a movable shelf where the shelf front surfaces of each movable unit shelf are in contact with each other during convergence, a paper core made of moisture control paper in which powder having moisture absorption and desorption ability has been soaked is inserted into the movable shelf. Since the shelf is attached to the inner surface of the shelf exposed to the shelf space, when the humidity in the air increases, the moisture in the air inside the movable shelf will be absorbed by the paper core, and the moisture absorbed by the paper core will be absorbed by the movable shelf. As a result, the humidity in the air inside the shelf is maintained at a substantially constant level, so that the quality of the books and other items stored in the movable shelf can be preserved without deterioration. It becomes possible.

Further, in the present invention, when an outer plate is attached to one side or both sides of the paper core, the paper core is supplemented and reinforced by the outer plate, and in which posture the paper core is attached to the shelf. Even when attached to the inner surface, it retains its shape.

Furthermore, in the present invention, when the outer plate attached to the paper core is made of the same material as the paper core, the paper core can be supplemented and reinforced, and the amount of moisture control paper used and its surface area can be increased. The humidity control function can be further improved.

Furthermore, in the present invention, since the paper cores are attached to the lower or upper surfaces of a large number of shelf boards installed at intervals in the vertical direction, a large number of paper cores can be placed close to articles such as books. , it is possible to obtain a mobile shelf with high humidity control function.

Moreover, in the present invention, since the paper core is attached to the inner surface of the back plate or side plate provided on the movable shelf, the movable shelf can be provided with a humidity control function without having to attach the paper core to the shelf board. In addition, when the paper core is attached to the shelf board, the humidity control function can be greatly improved.
