By the way, most of conventional resin decorative boards are used in a fixed state like the above-mentioned ceiling material. The decorative board made of resin is not used for a part to which a strong impact is applied, since the decorative board has a weak impact resistance and is cracked or cracked. For example, the door of the organizing shelf that rotates in the front-rear direction via the hinge described above can use a conventional resin plate because a large impact is applied when the organizing shelf main body and the door collide when the door is closed. Instead, a thin wood plate or a steel plate was used for such a door.

Each decorative board 10 obtained as described above was cut into a size of 500 mm in length and 340 mm in width to form the opening / closing door 40 of the embodiment. The door 40 was attached to a hinge (not shown) of the organizing shelf 50. Further, a handle 41 having a role of a weight when closing the door 40 is provided at the center of the lower end of the door 40. In addition, the lighting fixture 60 was arranged in the sorting shelf 50. When the handle is released from the open state, the door 40 collides with the organizing shelf and closes while receiving an impact, as shown in FIG.

As a result of the test, the doors of each embodiment are excellent in impact resistance, are not damaged even if the doors are repeatedly opened and closed frequently, and are excellent in impact resistance even in an iron ball drop test. It was confirmed that. Further, the opening and closing doors of Comparative Examples 1 and 2 can be seen through the light source itself, whereas in each of the examples, they could not be seen through the light source itself. Therefore, the opening and closing door glowed brightly, and had a decorative property different from the opening and closing doors of Comparative Example 1 and Comparative Example 2. Furthermore, the opening and closing door of the wooden board of Comparative Example 3 and the shutter of Comparative Example 4 lacked light transmittance and lacked decorativeness. Comparative Example 5 did not crack by the natural opening and closing of the door, but cracked in the iron ball drop test and could not withstand a strong impact.

The present invention has the following effects because it is configured as described above. That is, according to the opening and closing door of the present invention, since it has excellent impact resistance, it can be widely used as an opening and closing door in a portion to which an impact is applied. In addition, since it is made of resin and is lightweight, it is excellent in handleability such as workability. Further, by imparting light transmittance to the door of the present invention, it is possible to provide a door which is used for a part to which a shock excellent in design is applied.
