Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sliding rotary door device that can hold a closed state without rattling only by locking one end of a door panel.
[0002]
[Prior art]
Conventionally, an upper rail is provided at the upper part of the frontage, a door panel is hung on the runner that moves the upper rail, and a U-shaped frame is attached to the vertical frame on one side of the frontage so as to be rotatable. A sliding-type rotary door device that can open and close the front door by rotating the door panel by connecting the upper and lower arm tips to the upper and lower ends of the door panel via a shaft is disclosed in many publications such as JP-A-11-50732. Although disclosed, the provisional locking device for locking the door and the handle for operating the device were provided on the vertical frame side of the frontage opposite to the attachment position of the frame body.
[0003]
[Problems to be solved by the invention]
In such a sliding-type revolving door device, unlike a door in which one end of a normal door panel is hinged to a vertical frame of a joinery frame, the door panel turns around a shaft portion of a runner when the door opens. A temporary locking device that is locked and unlocked by a handle operation for holding the door in a closed state is provided on the door panel opposite to the frame that controls the movement of the door panel, and the runner's In the conventional door device in which the mounting position is biased in the direction opposite to the frame body from the center of the door panel due to its structure, the end of the door panel opposite to the temporary locking part is free and the door panel is free of wind pressure. However, there was a drawback that it fluctuated greatly.
[0004]
Therefore, in order to solve this drawback, a rod that reciprocates left and right in conjunction with the movement of the handle that operates the temporary locking device and is engaged with and disengaged from the rotating shaft of the frame is provided inside the door panel, and the temporary locking is performed. Both ends of the door panel, i.e., two points, are locked by the latch bolt and the rod of the apparatus to prevent the door panel from shaking as described above.
[0005]
However, if the door panel is hollow such as a sash panel, there is no problem in providing the rod through the door panel, but the door panel is made of wood or glass. In such a case, there is a problem that implementation is difficult.
[0006]
