Claims

[Scope of utility model registration request]

A shoji is attached to a window frame so that it can swing freely about an axis parallel to one side of the window frame, and a threaded rod is supported on the window frame so that it can freely rotate only about the axis. A swinging opening/closing window in which a non-rotatably screwed female screw body and the shoji are connected by a link, and the shoji is swung in both opening and closing directions by the screw movement of the female screw body caused by the rotational drive of the threaded rod. In the opening/closing device, a threaded rod for lock operation is supported on the window frame so as to freely rotate only about the axis with the axis oriented in a direction perpendicular to the direction in which the shoji approaches and leaves the window frame, and the lock operation A threaded rod for lock operation is connected to the threaded rod so as to be able to rotate in conjunction with each other by interlocking screw gears, etc., and a female threaded body for lock operation is connected to the threaded rod for lock operation so that it cannot rotate around the axis. screwed together, and does not interfere with the lock operating female screw body and the shoji when the shoji swings, and
A swinging opening/closing window characterized in that a pair of engaging portions are formed that engage with each other at the same time as the shoji contacts the window frame to prevent the shoji from swinging in the window opening direction. Device.
