Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a shelf having a humidity control function.

Prior Art Paper used for books expands and contracts in response to changes in humidity, and its strength also changes significantly, and if this continues for 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, a humidity control agent such as silica gel or alumina gel is applied to the space where these items are stored. They were placed in a plastic bag, and the moisture conditioner was used to maintain the humidity at a nearly constant level.

Problems to be Solved However, 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, so its short-term humidity control function is poor. Also, you will need space to place it, so
The storage space becomes narrower, and this often becomes a hindrance when putting in and taking out items to be stored.

Means and Effects for Solving the Problems The present invention relates to an improvement of a shelf that overcomes such difficulties, and in which a shelf equipped with a back plate can be used even with moisture-control paper containing powder having moisture absorption and desorption ability. The present invention is characterized in that a panel is attached to the inner surface of the back plate, which is made by pasting an outer plate on one or both sides of a paper core.

Since the present invention is configured as described above,
When the humidity in the air increases, the moisture in the air inside the shelf is absorbed by the paper core attached to the back plate, and when the humidity in the air decreases, the moisture absorbed in the paper core is absorbed into the shelf. is dissipated into the air,
As a result, the humidity in the air inside the shelf is kept constant.

Further, in the present invention, since the outer panel is attached to one or both sides of the paper core, the rigidity and strength of the panel is increased, and the outer panel is attached to the inner surface of the back panel that is erected along the vertical plane. The panel can maintain its planar shape without deformation.

Furthermore, in the present invention, since an outer plate is attached to one or both sides of the paper core and the outer plate is made of the same material as the paper core, the surface area of the humidity control paper increases and the humidity control function is further enhanced. improves.

Furthermore, in the present invention, the shelf provided with the back plate is configured as a double shelf in which shelf booths are partitioned in the front and rear by the back plate, and a plurality of the paper cores are attached to the back plate. The paper cores are placed on both sides of the back plate in a staggered manner in one or both of the vertical and horizontal directions so that the paper cores are not attached to the opposite side of the back plate to which the paper cores are attached. Since a plurality of paper cores are attached, the humidity in the air in the space between the shelf booths on both the front and rear sides of the multiple shelves can be maintained evenly.

Moreover, in the present invention, since a large number of small holes are provided in the back plate of the double shelf, the front and rear shelf booths partitioned into the front and back can be communicated with each other, and the humidity in the air in the space between the two shelf booths can be made uniform. .

Moreover, in a state where the upper and lower surface parts 13 of the two upper and lower back plates 10 are superimposed on each other,
A male screw 18 is passed through the hole 16 in both the upper and lower surface parts 13, and a female screw 19 is screwed and tightened to the tip of the male screw 18, so that the back plate 10 is arranged flush in the vertical direction. can be integrally combined with each other.

As shown in FIGS. 7 and 8, the panel 20 attached to the back plate 10 and the shelf board 30 includes a hexagonal paper core 21 and a water-soluble polyvinyl alcohol-based or acetic acid-based material on both sides. Outer panel 2 attached together with vinyl adhesive
2, and the hexagonal paper core 21 and outer plate 22 are made of moisture control paper in which silica gel, alumina gel, allofene, zeolite, or other powder having moisture absorption and desorption ability is mixed.

Further, a large number of small holes 23 are uniformly provided over the entire surface of the outer plate 22.

Further, in the steel plate shelf board 30, the front and rear surfaces 32 are formed by bending the front and rear ends of the top surface 31 downward at right angles.
A folded portion 33 is formed by further bending the tip end at a right angle inward from the lower edge of 2.

Furthermore, a panel presser spring 34 is attached to the inner surface of the front and rear surfaces 32.

Since the embodiment shown in FIGS. 1 to 8 is constructed as described above, the back surface 1 of the back plate 10
1 and the upper folded front part 14a, and from the state where the panel 20 is pulled up, lower the panel 20 and insert the panel between the back part 11 and the lower folded front part 14b. 20
The panel 20 can be attached to the front surface of the back part 11 of the back plate 10 by fitting the lower part of the panel 20 .

A panel 20 is attached to the lower surface of 0.

Furthermore, inside the humidity control shelf 1, since panels 20 are attached to the front of the back board 10 and the bottom surface of the shelf board 30, the air in the humidity control shelf 1 is transferred to the front of the back board 10. When the panel 20 attached to the lower surface of the shelf board 30 is touched and the panel 20 is made of humidity control paper in which powder having a moisture absorption and desorption function has been soaked, the air in the space inside the humidity control function shelf 1 is , books (not shown) placed on the shelf board 30 can be kept at a substantially constant humidity without being significantly affected by changes in the humidity in the outside world, and can avoid deterioration due to changes in humidity over a long period of time.

Furthermore, since the surface area of the hexagonal paper core 21 is extremely large and the panel 20 is located close to the book, the humidity control function is extremely high. and back plate 10
condensation is less likely to form on the front surface of the shelf board 30 and the surface of the shelf board 30.

Moreover, since the outer panels 22 are attached to both sides of the hexagonal paper core 21, the rigidity of the panel 20 is increased, and the panel 20 will not be deformed even if it is placed on a vertical or horizontal surface.

In addition, the back plate 10 is made by bending a single thin steel plate and fixing the left and right side parts 12 to the sides 2b of the column 2 with screws 17 passing through the holes 15 in the left and right side parts 12. serves as a reinforcing material for the humidity control function shelf 1 and can increase its strength and rigidity.

Furthermore, the paper cores 21, 25, and 26 have high rigidity, and the paper cores 2 are erected along the vertical plane.
If the cell shapes of cells 1, 25, and 26 are difficult to deform, the outer plate 22 is unnecessary.

Furthermore, in order to improve the adhesion between the paper cores 21, 25, 26 and the outer panel 22, the outer panel 22 may be made of ordinary paperboard.

In addition, the humidity control function shelf 1 was a single steel double-column shelf, but as shown in FIGS. It may be a steel double-column double shelf 40 in which a back plate 10 is attached to the central pillar 41, and the back plate 10 partitions a shelf booth into the front and back. The front and back sides of the back plate 10 are arranged in a staggered manner.

In the embodiment illustrated in FIGS. 13 and 14,
Since the panels 20 are alternately exposed in both the front and rear shelf booths, both have a substantially equal humidity control function.

Furthermore, as shown in FIG.
Since air comes into contact with both the front and rear of the panel 20 in the panel 3, an even higher humidity control function can be exhibited.

In the embodiments described above, the back plates 10 and 43 were constructed by bending thin steel plates, but the back plates may also be constructed by stretching thin plates on a suitable frame member.

Further, in the embodiment described above, the humidity control function shelf 1 is of a double-post type, but it may be of a single-post type.

Effects of the Invention In the present invention, since a panel having moisture absorption and desorption ability is disposed on the inner surface of the backboard, the air inside the shelf is absorbed and desorbed by the panels located inside the panel. The humidity of the air inside the shelf can be maintained constant,
As a result, the books and other articles placed on the shelves can be stored without deteriorating in quality.

Further, in the present invention, panels are attached in a staggered manner in the vertical direction on the front and back sides of the back plate in a double shelf in which shelf booths are partitioned in the front and back by thin plate back plates, or a large number of panels are attached to the thin plate back plate in a staggered manner. Since the small holes are provided, the humidity control function can be equally exerted in the spaces between the front and rear shelves of the multiple shelves.
