2. Description of the Prior Art The bathroom door is normally opened only to the bathroom side in order to prevent water from entering the dressing room side, so that it is not opened to the dressing room side, and the bathroom side is not opened. The door to the dressing room cannot be opened even if the door is locked from the door. It is necessary to be able to open to the dressing room side by the operation of.

[0003] In order to enable opening from the dressing room side,
If an escape door that opens and closes independently is stored in the frame of the bathroom door, it is necessary to install a lock that keeps the escape door closed, but the bathroom door only has a main body during normal use. Because of the opening and closing, it is required to have the appearance of a mere bathroom door, so that the lock should not be exposed. Exposure of the lock is avoided by storing it inside the frame of the escape door. However, in the case of a normal lock, the width of the frame can be easily expanded by storage, so that the escape door is emphasized.

The present invention has been made in view of the above background, and an object of the present invention is to propose an unlocking device that avoids exposing a lock for an escape door and suppresses an increase in the width of a frame.

[0005]

According to the present invention, an engaging member for locking an emergency escape door which can be opened from the bathroom door body to the dressing room side in an emergency in a normal state is housed freely from the frame to the frame side. Engaging the members on the frame on both sides in the direction of view and keeping them closed, the expansion of the width of the frame is suppressed, and the appearance of the bathroom door with escape door is maintained as a pure bathroom door.

The engaging member is housed in the engaging frame which normally engages with the frame in the frame framed by the emergency exit door so as to be able to freely enter and exit in the finding direction, and is always biased toward the frame. In normal times, it projects to the frame side and engages on both sides of the frame in the expected direction, and keeps the emergency exit door closed.

The release of the engaging member from the frame is carried out by a releasing member which is housed in the frame and presses the engaging member against the urging frame against the bias during operation.

An engagement member which is kept locked in normal times and is unlocked in an emergency and a release member for operating the engagement member are stored in an engagement frame and a frame, respectively, so that exposure is avoided. By maintaining the locked state by engaging the frame in the expected direction, the width of the frame can be prevented from being increased, and the appearance of the bathroom door is maintained at the same level as a bathroom door without an emergency escape door.

The engaging member has a continuous length in the longitudinal direction of the frame, thereby stabilizing the emergency exit door against rattling against the frame.
