Claims

[Scope of utility model registration request]

Two movable doors that slide in the horizontal direction are arranged so as to be shifted in the width direction, and are configured so that they can be moved by switching between a normal opening and an opening above the normal opening,
A fixed door is provided on one side of the two movable doors, shifted in the width direction thereof, and each outer end of the three doors is pivoted by a pin so that the three doors can swing. A locking mechanism is provided on the inside of each of the doors, and when the above two movable doors are moving within the normal opening degree, the locking mechanism is activated to prevent the three doors from swinging. Among the movable doors, when the movable door closest to the fixed door is moved at half the speed of the other movable door, and the above two movable doors move beyond the normal opening degree, the lock mechanism is activated. A door opening/closing mechanism characterized in that the three doors can be opened and closed by swinging using the pin as a fulcrum in a state in which the three doors are overlapped in the width direction.
