As the sash, there is a sliding door sash mainly composed of a sash frame attached to an opening of a building and a shoji mounted on the sash frame so as to be horizontally openable and closable.

In such a sash, the shoji itself has an airtight structure, and an airtight material is provided between the shoji and the sash frame and between the shoji inside and outside so that the airtightness can be maintained. ing.

[0004]

However, in the above-mentioned sash, when the sash is installed especially in a building that is easily subjected to wind pressure, a wind pressure higher than the pressure on the indoor side is applied to the shoji from the outdoor side. Has a problem that it is difficult to open the shoji. Even when the pressure is not applied, the shoji is pressed against the airtight material when it is locked by the crescent, which is a locking device, so that the shoji is in a close contact state, and it may be difficult to open the shoji even when the crescent is unlocked.

Therefore, an object of the present invention is to solve the above problems and provide a sash that can be easily opened by a simple operation even if the screen is difficult to open due to wind pressure or the like. is there.

[0006]

In order to achieve the above object, the sash of the present invention is provided with a hook portion on the indoor side of the door end frame or the assembling frame of the shoji mounted on the sash frame,
A lever member having an output end capable of being hooked to the hooking portion is supported on the fixed side of the vertical frame of the sash frame corresponding to the hooking portion, the vicinity of the vertical frame, the other frame or the lower frame of the sash frame. It is characterized in that it is rotatably provided via a shaft, and the shoji is forcibly opened by hooking the output end of the lever member to the hook portion and turning the lever member.

In this case, the hooking portion may be, for example, a concave portion such as a groove, a convex portion such as a rib, or an inner end portion of the assembling frame. Further, it is preferable that the lever member is provided so as to be horizontally rotatable via a support shaft. Further, it is preferable that the lever member is retractable or rotatable so that the output end does not interfere with the door end frame when not in use. As a mounting position of the lever member, a position corresponding to the hooking portion, that is, when the hooking portion is provided on the door frame, for example, an upper frame or a lower frame in the vertical frame of the sash frame or in the vicinity of the vertical frame, Or a frame,
