DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base sliding door and a sliding door. More specifically, the present invention relates to preventing sliding of four corners of a sliding surface of a sliding door, referred to as corner wrinkles, and reducing the thickness of the base paper. The present invention relates to a method in which ground paper can be removed together with a frame by a plane.

[0002]

2. Description of the Related Art A sliding door is constructed by assembling a middle bone into a lattice like a shoji, pasting paper or cloth from both sides thereof, and attaching a sliding edge to the periphery. Cedar wood is used for the middle bone mainly because of its lightness.

At present, the manufacturing of fusuma is a division of labor, and a fusuma fusuma, that is, a central frame arranged in a grid in a vertical frame and a horizontal frame is disposed, and a base paper is stretched on both front and back sides. What is being made is manufactured by the manufacturer of the sliding screen,
The installation of the fusuma rim and the installation inside the room are performed by a surface maker.

[0004] The sliding door is generally installed in a space surrounded by a threshold, a sill, and a pillar. Although the interior of the house is built according to standards, the dimensions vary slightly, albeit slightly. In that case, the frame of the ground sliding door is cut with a plane, and the building is rebuilt so that the sliding door fits neatly in the space surrounded by the sill, the floor and the pillars.

[0005]

SUMMARY OF THE INVENTION In the case of a conventional ground fusuma,
When the frame was cut with a canna, only the wooden part, that is, the part of the frame, was cut off, and the part of the base paper was left turned up. For this reason, the remaining paper had to be scraped off later with sandpaper or the like, which required an extra step.

The present inventor has repeatedly studied whether the base paper can be cut with a canna together with the frame. The thickness of the paper affixed to the base fusuma is generally 3 × 6 and weighs 350 g. Therefore, we focused on changing the thickness of the paper and conducted an experiment.
It was found that if it was less than g, it could be shaved together with a canna.

[0007] Fusuma sliding doors are used as partitions. In a situation where heating is performed inside a room but not outside as in winter, there is a considerable temperature difference between the outside and the inside of the room. In such a case, the sliding door will bend and bend to the side with poor elongation due to the difference in elongation due to thermal expansion. When the fusuma is warped, wrinkles are formed from the four corners of the fusuma surface toward the center. Conventionally, it was considered that this corner wrinkle could not be helped.

[0008] The present inventor has repeated researches to prevent the occurrence of corner wrinkles, and impregnated with resin at the four corners of the base sliding door to add rigidity.
It has been found that corner wrinkles can be prevented by arranging the provided paper honeycomb core . The present invention has been completed based on these findings.

An object of the present invention is to prevent wrinkles from being formed at four corners of the surface of a sliding door, which are called corner wrinkles, and to reduce the thickness of the base paper so that the base paper can be used together with the frame. In order to be able to scrape off.

[0010]

Means of the present invention taken to achieve the above object are as follows. According to the first invention, in a base sliding door in which a middle rib arranged in a lattice is disposed inside a vertical frame and a horizontal frame, and a base paper is stretched on both sides, Four corners are impregnated with resin to give rigidity
A base sliding door, characterized by being provided with a honeycomb core made of paper .

According to the second aspect of the present invention, there is provided a grid framed inside a vertical frame and a horizontal frame, and a base paper having a base paper stretched on both sides. In the sliding door, the base paper is a base sliding door characterized in that the weight per area of 3 × 6 is 300 g or less.

According to a third aspect of the present invention, there is provided a sliding door using the ground sliding door according to the first or second aspect.

If the base paper is 300 g or less in a size of 3 × 6 and the paper thickness is about 0.27 to 0.40 mm,
The ground paper can be scraped off with a plane along with the frame.
It is preferably 250 g or less, and considering other conditions such as workability and strength, 230 g (0.32-0.3 in terms of paper thickness)
About 4 mm) is preferable. In the case where the base paper is made thin, the overall thickness of the base sliding door is ensured by increasing the thickness of the middle bone, and the specified dimensions are ensured.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 is a front view of a base sliding door according to the present invention, showing a state in which a part of one base paper is cut off. In the drawing, reference numeral 10 indicates a base sliding door. The base sliding door 10 has two vertical frames 11 and 11 and two horizontal frames 12 and 12 and is surrounded by the vertical frames 11 and 11 and the two horizontal frames 12 and 12 to form a grid. An inserted middle bone 13 is provided.

Two vertical frames 11, 11 and two horizontal frames 12,
The base paper 1 is provided on both sides of the bone member formed by the
4, 14 are stretched. Recycled paper is used as the base paper 14, and the weight per area of 3 × 6 is 230
g is used. The thickness of the base paper and the frame together is 17 mm.

Masu 15, 15, 15, at the four corners of the base sliding door 10
15 corner corners are provided with paper- shaped corner cores 16, 16, 16, 16 which are honeycomb-shaped cores . The corner core 16 has a size of 10 cm × 9 cm and a feather core (J
IS A 6931) is used, and is impregnated with a resin to provide rigidity.

The manufacture of the base sliding door 10 according to the present embodiment is performed as follows. First, the horizontal frames 12, 12, the vertical frames 11,
The bone member is formed by assembling the 11 and the middle bone 13. afterwards,
A bond-based adhesive is applied to one side of the horizontal frames 12, 12, the vertical frames 11, 11 and the middle bone 13, and the base paper 14 is attached. Next, an adhesive is applied to the contact surfaces of the corner cores 16, 16, 16, 16, and the horizontal frames 12, 12 and the vertical frames 11, 11 are applied.
And glue it.

The horizontal frames 12, 12 and the vertical frames 11, 11
Then, a bond-based adhesive is applied to the other surface side of the middle bone 13 and the base paper 14 is attached. The fusuma is obtained by attaching an upper paper (decorative paper) to the surface of the above-described base fusuma 10 and attaching the fusuma rim. The invention is not limited to the embodiments shown, but numerous modifications are possible within the scope of the claims.

[0019]

The present invention has the above-mentioned structure and has the following effects. (A) Rigidity is imparted by impregnating the resin at the four corners of the underlying fusuma
Since the honeycomb core made of paper is provided, it is possible to prevent wrinkles from being formed at four corners of the surface of the sliding door, which is called a corner wrinkle, and is excellent in appearance. (B) The base paper weighs 30 times the size of 3 × 6.
Since the material having a weight of 0 g or less is used, the ground paper can be removed together with the frame by a canner, and the grinding operation can be performed in one step, so that the work efficiency in assembling can be improved.
