Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window provided on a wall of a building, a condominium, or a general house, and more particularly to a device for attaching an airtight material provided on an inner periphery of a shoji which is openably and closably mounted on a window frame.

[0002]

2. Description of the Related Art In general, windows are provided on walls of buildings, condominiums, and general houses, and a shoji is mounted in the window frame so as to be openable and closable. When the shoji is closed, the airtight material is brought into contact with the outer surface of the window frame to prevent outside air and rainwater from entering from outside.

A shoji is made up of upper and lower frames made of aluminum material for holding a glass plate as a surface material, and left and right rigid frames. Usually, an airtight material is attached only inside the upper and lower frames. However, if airtight material is attached only to the upper and lower frames, outside air, rainwater, etc. may enter from the inside of the rigid frame, so ants are installed inside the upper and lower frames and the left and right rigid frames to improve airtightness and watertightness. There have also been developed ones in which grooves are formed and airtight materials are attached to the inside of the upper and lower stiles and the inside of the left and right stiles via the dovetail grooves, respectively.

[0004]

However, even in such a case, the airtight materials between the both ends of the upper and lower frames and the both ends of the left and right frames are merely attached and not continuous. In addition, a seam is formed between the hermetic materials, and outside air and rainwater may enter from this seam, and it is still insufficient for complete sealing.

Therefore, it is naturally conceivable to further improve the airtightness and watertightness by disposing an airtight material along the entire inner periphery of the shoji. However, in this case, there are the following problems.

[0006] First, in order to arrange airtightness all around the inside of a shoji, an annular airtight material may be fitted into dovetail grooves provided inside the upper and lower frames and the left and right rigid frames. Since each frame is formed separately and each frame is cut at the end, when the airtight material is fitted in the dovetail groove of each frame, this airtight material will be sharp edge edge of the dovetail groove on the upper and lower frame side or When stress concentrates on the end edge of the dovetail groove of the left and right frame, the airtight material may be damaged at this edge and may be cut in some cases. Therefore, if the airtight material is prevented from being hooked on the edge of the dovetail groove, the airtight material cannot be held at the corners, causing the airtight material to sag, protrude, or fall off.

Second, if the corners of the dovetail groove are made continuous at right angles by specially processing the ends of the upper and lower frames and the left and right rigid frames, an airtight material can be fitted around the entire circumference along the dovetail groove, and airtightness can be achieved. Damage to the material is also prevented, but in this case, the processing of the upper and lower frames and the left and right frames is complicated, the combination of both is complicated and difficult, and it becomes difficult to attach the airtight material and the appearance is impaired. .

Accordingly, an object of the present invention is to provide a hermetic material that can be seamlessly disposed all around the inside of a shoji to improve hermeticity and watertightness. It is an object of the present invention to provide a device for attaching an airtight material to a window, which can be easily attached, can easily assemble upper and lower frames and right and left rigid frames, and can improve the appearance.

[0009]

In order to achieve the above-mentioned object, a means of the present invention comprises a window frame and a shoji which is openably and closably mounted in the window frame. The window is formed in a square shape with upper and lower frames and left and right frames that hold the surface material, and an airtight material that contacts the outer surface of the window frame on the inner periphery of the upper and lower frames and the left and right frames. A first dovetail is formed along the horizontal direction inside the upper and lower stiles, a second dovetail is formed along the vertical direction inside the right and left stiles, and the upper and lower stiles and the left and right stalls are further formed. A corner joint having a third dovetail groove on the inside between the ends of the frame is detachably attached, and an airtight material is fitted into the first, second and third dovetail grooves. Things.

In this case, the upper frame and the left and right rigid frames are composed of a support plate standing at the end of the hollow frame main body and first and second dovetail grooves provided on the inner peripheral side of each support plate. Is preferred.

Similarly, the corner joint is a spacer removably fitted to an end of a hollow frame main body of a rigid frame or an upper and lower frame, a horizontal cap provided at the upper end of the spacer, and stands up and down at the end of the cap. It is preferable to include a support piece and a third dovetail groove formed in the upper part inside the support piece in the horizontal direction.
