In this state, when the operation handle 18 of the sliding door body unit 3 is pushed to the outdoor side, the swinging door body 1 and the panel unit 5 are integrally opened and closed with the upper and lower pivot shafts 1a and 4c as pivot points. Accordingly, the swinging door body 1 and the panel unit 5 are set to be opened as a hinged door. Here, the swinging door body 1 and the panel portion 5 are set so as to swing open in a connected state by the relative movement of the steadying roller 14 within the recessed groove portion 5c of the sliding door unit 3. Yes. In this state, the second lock bar body 23b is in the downward movement posture, and as described above, the panel portion 5 that swings open and close moves carelessly with the parallel movement of the frame portion 4. It is configured so that there is no such thing.
Reference numeral 25 denotes a steadying body that is provided on the inner side of the opening on one side and that serves to steady the door bottom side part (frame part 4) of the sliding door unit 3 in the fully open position.

  In the embodiment of the present invention configured as described above, the sliding door unit 3 moves along the suspension rail 6 and automatically moves because the suspension rail 6 is inclined when closed (self-closing). ). When the sliding door unit 3 is in an open posture to open the other side of the opening, the panel unit 5 of the sliding door unit 3 is configured to swing open to the outdoor side together with the swing door 1. For this reason, the swing door 1 is supported via the upper and lower pivots 1a. And in this thing, when making the panel part 5 of the sliding door body unit 3 function as a swing door with the swinging door body 1, the sliding door body unit 3 will be made into a fully open attitude | position, However, in this thing, the said sliding door body unit 3, when the sliding door drop lock 24 and the swing door drop lock 17 are unlocked so as to swing the sliding door unit 3, the second safety in a state interlocked with the sliding door drop lock 24. The second lock bar body 23b of the device S2 is in a downward movement posture and is in a positional relationship capable of contacting the second guide piece 21 located on the open side. As a result, even when the frame portion 4 of the sliding door unit 3 is about to move to the closing side in the process of swinging the panel portion 5, the second lock bar body 23b abuts on the second guide piece 21 and beyond. Therefore, when the swinging door body 1 and the panel portion 5 are swung together, loads other than the swinging direction are applied to the panel portion 5 and the frame portion 4. Even if it is closed, the sliding door body unit 3 (frame portion 4) does not perform an inadvertent movement that translates to the other side, so that the swinging door body 1 and the panel portion 5 can be stably opened and closed. And it can be operated with good operability.

  Further, in this case, the second safety device S2, which is the parallel movement restricting means, moves the second lock bar 23b in conjunction with the unlocking operation of the sliding door body dropping shape 24 that is operated when the sliding door body unit 3 is rocked. When the second lock bar 23b in the downward movement posture is about to move in the closing direction, the second lock bar 23b comes into contact with the second locking piece 21 to restrict the movement to the side. There is no need to perform a separate operation for regulation, and you will never forget the operation.

  In addition, in this case, the second safety device S2 is configured so that the sliding door unit 3 reaches the arbitrary open position set in advance, that is, the open position beyond the second guide piece 21, and the second lock bar body 23b. When the second lock bar body 23b is displaced to the downward movement position on the closing side, the frame portion 4 is opened when the second locking bar body 23b is displaced to the downward movement position. Since the parallel movement of the direction is allowed, the sliding door unit 3 can be opened for the time being.

  In addition, in this structure, the frame part 4 and the panel part 5 include a sliding door drop lock 24 that is a locking means, and a sub-lock that automatically releases the posture holding when the sliding door unit 3 is displaced to the fully open posture. The first safety device S1 as the means holds the double position in the closed position, so that the sliding door drop lock 24 is unlocked when the sliding door body unit 3 is not in the fully open position. However, the panel portion 5 is not opened and closed and the operability is good.
