Description

  The present invention relates to a shoji structure.

A general shoji has a structure in which shoji paper is pasted on the front surface or the back surface of a koji placed in a shoji frame. The shoji is used for the inside of the sash, the partition, etc., and can be blinded with daylighting.
In recent years, there has been a demand for improvement in heat insulation of a house, and there is a need for a shoji that has heat insulation and can be daylighted and blindfolded.
When a shoji screen is provided with a heat insulating function, a shoji paper sticker is pasted on the front and back of the shoji, as in the case of a drum sticking shoji generally used in cold regions, and an air layer for heat insulation is provided between the two shoji paper. That keeps heat insulation.
Further, Patent Document 1 describes that by arranging a face material made of a synthetic resin sheet between two shoji papers, the air layer is increased to two layers to increase heat insulation. Yes.

JP 2011-153415 A

However, as in the above prior art, when the heat insulating property is obtained by the air layer formed between the two sheets of shoji paper (decorative paper), the surface of the braid is covered with the shoji paper. Designability will be inferior.
The present invention has been made paying attention to the above points, and an object thereof is to provide a shoji that has a heat insulating function while ensuring designability (interior property).

In order to solve the problem, one aspect of the present invention is a shoji comprising a shoji frame and a kumigami incorporated in the shoji frame, wherein the koji is arranged on the front side of the shoji. And a second braid disposed on the back side of the shoji, and further interposed between the first and second braids and the vertical saddle member and the reed of the shoji frame. In addition to having a heat insulating sheet extending toward the material, no shoji paper is provided on the surfaces of the first and second sets to cover the entire kumiko pattern composed of the sets. And
Note that the kumiko pattern by the first kumiko and the kumiko pattern by the second kumiko may be different.

  According to one embodiment of the present invention, it is possible to give the shoji a heat insulating function while ensuring the design by the kumiko pattern.

It is the figure seen from the front which shows the shoji which concerns on embodiment based on this invention. It is a longitudinal cross-sectional view of the shoji which concerns on embodiment based on this invention. It is a fragmentary cross-sectional view explaining the connection part of a vertical gutter and a heat insulation sheet. It is the figure which looked at the shoji from the upper part. It is a figure which shows the example of a kumiko pattern, Comprising: (a) shows the example of a torn well, (b) shows the example of a flower kumiko, (c) shows the example of a raft.

Next, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the shoji 1 according to this embodiment includes a shoji frame, a braid 13, and a heat insulating sheet 14. This shoji 1 is used as, for example, an inner window shoji disposed inside the sash.
As shown in FIG. 1, the shoji frame is composed of a pair of left and right vertical saddle members 12, an upper vertical member 10 spanning the upper end of the pair of vertical saddle members 12, and a pair of vertical saddle members 12. It consists of the lower brace material 11 spanned by the lower end part. Upper gutter material 10 and lower gutter material 11 constitute a horizontal gutter material.

The shoji frame is manufactured from, for example, a wooden square. The shoji frame may be made of metal.
The kumiko 13 is incorporated in the shoji frame and supported by the shoji frame. In FIG. 1, the case where a braid pattern is a grid | lattice form is illustrated and the vertical braid and the horizontal braid | blade are assembled | attached on the grid | lattice form. Note that the kumiko pattern formed by the kumiko 13 is not limited to the lattice pattern. A kumiko pattern of various designs as shown in FIG. 5 can be adopted.
As shown in FIGS. 2 and 3, the pair 13 according to the present embodiment includes a first pair 13 </ b> A disposed on the front side of the shoji 1 and a second pair 13 </ b> B disposed on the back side of the shoji 1. It consists of two sets of kumiko. In FIG. 2, the right side is the front side of the shoji 1.

A flat space (hereinafter also referred to as a sheet insertion space) extending in the upward direction and the left-right direction is formed between the first assembly 13A and the second assembly 13B. In the position, neither the first braid 13A nor the second braid 13B is arranged.
2 and 3 exemplify the case where the arrangement patterns of the first assembly 13A and the second assembly 13B are the same. However, the braid pattern formed by the first braid 13A and the braid pattern formed by the second braid 13B may be different. In this case, the location where the first assembly 13A and the second assembly 13B are not arranged at the same height in the thickness direction of the shoji 1 occurs.

Grooves 10c, 11a, and 12a are formed in the sheet insertion space on the inner peripheral surface of the shoji frame. That is, grooves 10c, 11a, and 12a for inserting the heat insulating sheet 14 are formed in the left and right vertical saddle members 12, the upper saddle member 10, and the lower saddle member 11. Each groove | channel 10c, 11a, 12a is formed so that it may extend along the axial direction of each member.
The heat insulating sheet 14 has a rectangular shape similar to the rectangular shape of the shoji frame. The heat insulating sheet 14 is arranged in the above-described sheet insertion space, and is arranged such that each side constituting the end portion is inserted into the corresponding groove 10c, 11a, 12a. That is, the heat insulation sheet 14 is plugged into the grooves 10c, 11a, and 12a formed on the inner peripheral surface of the shoji frame, thereby closing the rectangular opening formed in the shoji frame.

The heat insulating sheet 14 is made of, for example, a resin nonwoven fabric having a thickness of 5 mm to 10 mm. The heat shielding sheet is not transparent enough to see the other side, but preferably has a daylighting property.
The resin nonwoven fabric constituting the heat insulating sheet 14 is made of, for example, a polyester or polyethylene resin. Here, the nonwoven fabric is a sheet in which fibers are entangled without being woven.
The reason why the thickness is set to 5 mm or more and 10 mm or less is to ensure the daylighting property while ensuring the blinding effect and to ensure the predetermined heat insulation property. In addition, by setting the thickness, it is possible to impart a predetermined rigidity to the heat insulating sheet 14.

  Moreover, as shown in FIG.2 and FIG.4, as for the upper collar material 10, the part which opposes the upper end part (upper side) of the heat insulation sheet 14 up and down is separable upward with respect to the main body of a shoji frame. 10b. That is, the upper eaves material 10 is composed of an upper eaves body 10a that opposes the first and second assemblies 13A and 13B in the vertical direction, and a fitting portion 10b that opposes the upper end (upper side) of the heat insulating sheet 14 in the vertical direction. Become. As shown in FIG. 4, the fitting portion 10 b has a longer length in the extending direction than the upper side of the heat insulating sheet 14 in a top view. That is, the fitting portion 10b protrudes left and right from the upper side of the heat insulating sheet 14 in a top view. For this reason, grooves for fitting the left and right end portions of the fitting portion 10b are also formed on the upper end surfaces of the left and right vertical saddle members 12, and the left and right end portions of the fitting portion 10b are supported by the grooves.

When the fitting portion 10b is provided, the entire sheet insertion space can be viewed from above by pulling the fitting portion 10b upward, and the heat insulating sheet 14 can be pulled out or inserted from the upper side of the shoji frame. It becomes.
Here, in this embodiment, the shoji paper is not provided on the surface of both the first assembly 13A and the second assembly 13B. However, for the purpose of improving designability, decorative paper may be provided only on a part of the surfaces of the first and second braids 13A and 13B, that is, on the front and back surfaces of the shoji. When the decorative paper is partially provided, a sealed heat insulating air layer is not formed.

The shoji 1 of the present embodiment is a heat insulating material that is a surface material having heat insulating properties at the middle part of the first and second kumigami 13A and 13B, with the kumigami 13 arranged on both the front side and the back side of the shoji 1 respectively. The sheet 14 is arranged, and the heat insulating sheet 14 has a heat insulating effect, daylighting, and a blinding effect.
In addition, since the koji 13 has a structure that can be seen on the front and back of the shoji, the shoji 1 has a heat insulating property and an excellent design by the koji pattern.
Further, by providing the fitting portion 10b, the heat insulating sheet 14 can be drawn out and inserted from the upper side (upper collar portion) of the shoji frame. That is, the heat insulating sheet 14 can be easily replaced. With this structure, the heat insulating sheet 14 can be replaced when it becomes dirty.
A pattern may be provided on the surface of the heat insulating sheet 14.
