Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash provided with a sliding door that is opened and closed by sliding.

[0002]

2. Description of the Related Art In a sash equipped with a sliding door that opens and closes in a sliding manner, the airtight state when the sliding door is closed is moved in one of the indoor and outdoor directions (often indoors), and This is achieved by closely attaching to the tight part provided on the sash frame side. For this purpose, a pulling device having a cam or a kicking piece is arranged inside the frame of the shoji, and the cam or the kicking piece is rotated by the operation part to move the shoji itself to the indoor side with respect to the sash frame. It has a structure (Japanese Utility Model Publication No. 58-11071, Japanese Utility Model Publication No. 58-101961, Japanese Utility Model Publication No. 1-8).
6673).

In this structure, when the sliding door is released from the retracted state in order to open it, the sliding door returns to the original traveling position by its own weight. Normally, a mechanism for positively returning the sliding door to the original traveling position is provided. Not prepared.

On the other hand, in view of the design of the window, it is sometimes preferable that the shoji and the sash have an airtight structure in which the shoji is moved to the outside and the outer surface of the shoji frame is brought into close contact with the tight portion provided on the sash frame. In particular, while basically opening and closing the sliding door on the outdoor side and the sliding door on the indoor side, when the window is closed, the sliding door on the indoor side moves to the outdoor side and is flush with the sliding door on the outdoor side. In the case of the sliding sash, it is common to move the shoji screen on the outdoor side to the outdoor side to maintain airtightness in order to maintain the advantage of being flush with each other.

However, with such a conventional sash, although the retracted state is released, the shoji and the tight portion are in close contact with each other and cannot be separated from each other, so that the shoji may be very heavy at the beginning. This state is likely to occur on the outdoor side shoji with the same plane-drawing sash. Further, it is difficult to maintain an average degree of airtightness between the indoor shoji and the indoor shoji with respect to the sash frame around the sash frame in the coplanar sliding sash.

Further, in the conventional sash, since a device for moving the shoji in the indoor and outdoor directions, such as a pulling device, is provided on the frame of the shoji, the space for mounting such a device is small, and it is necessary. It is difficult to obtain the one having the corresponding strength. For this reason, on a large and heavy luxury terrace sash,
There are some areas where it is difficult to adapt the attracting device.

[0007]

DISCLOSURE OF THE INVENTION The present invention has a sash having a shob which is opened and closed in a sliding manner, and one of the shoji is moved in one of the indoor and outdoor directions to maintain airtightness with the sash frame.
