Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door provided in a building such as a house.

[0002]

2. Description of the Related Art Conventionally, a fitting frame is provided at an opening of a Japanese-style room or the like of a house or the like, and a sliding door is attached to the fitting frame. , Plywood and the like are used, and the structure is bonded to the sliding door paper of the cover. In the case of corrugated cardboard,
No. 14525) is known. Further, since a temperature difference occurs between the sliding door and the room, such as in a passage, the environment is such that moisture often enters the sliding door. Therefore, a structure in which an aluminum foil is adhered to a base material to prevent moisture inside the fusuma is described (Japanese Utility Model Publication No. Sho 51-6912, etc.).

[0003]

However, under the above-mentioned environmental conditions, it is difficult to completely prevent moisture from entering the inside of the sliding door. It causes warpage and spots. Also,
If wood is used as the core material, there is a problem that the sliding door becomes heavy and the opening and closing operation becomes heavy. There is also a problem that the core material and the moisture-proof material are difficult to peel off when replacing the sliding paper because of glue bonding.

[0004] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to solve these problems, to provide an excellent moisture-proof property, and to reduce the weight and strength. It offers a certain fusuma.

[0005]

According to the first aspect of the present invention, there is provided a sliding door comprising a substrate and sliding paper attached to at least one side of the substrate, wherein the substrate comprises a plurality of sliding doors. The corrugated cardboard is formed by laminating the surfaces of the corrugated cardboard, and the corrugated cardboard is composed of two paperboards and a corrugated paper bonded therebetween, and is arranged so that the corrugated directions of adjacent corrugated paperboards are substantially orthogonal. And

Further, in the sliding door according to the present invention as set forth in claim 2, the surface of the substrate is covered with a moisture-proof material.

According to a first aspect of the present invention, there is provided a sliding door comprising a substrate and sliding paper bonded to at least one side of the substrate, wherein the substrate is formed by laminating a plurality of cardboard surfaces. Since the corrugated cardboard is composed of two paperboards and corrugated paper bonded therebetween, the corrugated paperboard is arranged so that the corrugated directions of adjacent corrugated paperboards are substantially orthogonal to each other. It can be made to be a durable fusuma.

In the sliding door according to the second aspect, since the surface of the substrate is covered with a moisture-proof material, it is possible to prevent moisture from entering the inside of the sliding door, to prevent warpage and to easily replace the sliding paper. Can be

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view showing a one-side cross section of an internal configuration diagram of a sliding door according to the present invention. The inside of the sliding door is constituted by making one side cross section of FIG. FIG. 2 is an explanatory view showing the structure of the cardboard of the substrate. FIG. 3 is a perspective view showing the moisture-proof material. The board of the above-mentioned sliding door is formed of a multi-layer corrugated cardboard 30 in which two layers of corrugated cardboard 30 are superposed and adhered to each other. The outer layer of the substrate is a sliding door covered with a moisture-proof material. Also, a corrugated cardboard 3 composed of multiple layers forming a substrate
0 are each covered with paperboard 33. The moisture-proof material forming the outer layer of the substrate is formed by laminating aluminum foil 21 on both sides with a plastic film 22, and sliding paper 11 is adhered to the outer surface of the moisture-proof material to form a sliding door. Since the outer surface of the substrate is protected with a moisture-proof material as described above,
Moisture can be prevented from entering the inside of the sliding door 11, and the sliding and warping of the sliding door 1 can be eliminated.

FIG. 2 is a perspective view showing a structure of a cardboard 30 forming a substrate. The two-layer corrugated cardboard 30 forming the board of the above sliding door has a corrugated paper 31 stuck on both sides with paperboard 33. Each cardboard 30, 30
Since the directions of the waves intersect at substantially right angles, the bending strength of the entire sliding door can be increased.

The cardboards 30 and 3 forming the substrate of the above sliding door
0 can be used in two or more layers, and the cardboard cover paper 33 may be any of gypsum base paper and recycled paper.

FIG. 3 is a perspective view showing the structure of the moisture-proof material. The moisture-proof material covering the outer surface of the corrugated cardboard layer of the above-mentioned sliding door board is a plastic film 22 on both sides of the aluminum foil 21.
It has a laminated structure. The film 2
By means of 2, moisture can be prevented from entering from the outside, and since the inside of the moisture-proof material is kept airtight, no dew condensation or the like occurs. Since the aluminum foil 21 is covered with the film 22, the shape of the aluminum foil 21 can be easily maintained. The plastic film 21 is preferably made of polyethylene, but may be another resin. The moisture-proof material and the substrate are attached with an adhesive.

On the outer surface of the moisture-proof material, fusuma paper 11 is stuck. The base material of the fusuma paper 11 has good adhesiveness because of the plastic film 22 forming the outer surface of the moisture-proof material.
When the sliding paper 11 is replaced later, the sliding paper 11 is easily peeled off and the work is easy.

The sliding door of the present embodiment is obtained by laminating and adhering two sides of a corrugated cardboard board 30 with their surfaces superposed on each other.
A moisture-proof material is formed on both outer surfaces of the sliding door, and the sliding board made of the board and the moisture-proof material is fitted and fixed to a frame material forming the outer periphery of the sliding door, and the sliding door paper is stuck to the surface of the sliding door to assemble the sliding door. . The sliding door assembled as described above can be a sliding door that is lightweight, hardly warped, and does not discolor.

In the sliding door according to the first aspect, the substrate is formed by laminating a plurality of corrugated boards 30 together and bonding the corrugated boards 30 to each other. Since it is arranged so that the directions of adjacent corrugated cardboard waves are substantially orthogonal, it is lightweight,
It can be a durable fusuma.

In the sliding door according to the second aspect, the moisture-proof material forming the outside of the substrate is laminated with a plastic film 22 on both sides of the aluminum foil 21 as a core. In this case, the infiltration of moisture is completely shut off, and the internal substrate is protected from external moisture. Therefore, it is possible to make a sliding door that is lightweight, hard to warp, and does not discolor.

[0017]

According to the sliding door according to the first aspect, the board comprises:
A sliding door comprising a sliding paper sheet attached to at least one side surface of the substrate, wherein the substrate is formed by laminating a plurality of cardboard surfaces, and the corrugated cardboard is attached to two paperboard sheets therebetween. Since it is made of corrugated paper and arranged so that the directions of the corrugations of adjacent cardboards are substantially orthogonal,
A lightweight and durable sliding door can be made by the base material with large compressive strength.

Further, in the sliding door according to the second aspect, since the surface of the substrate is covered with a moisture-proof material, it is possible to prevent moisture from entering the inside of the sliding door, to prevent warpage and to easily replace the sliding paper. Can be
