Thus, the open swing to the indoor side is restricted, whereby the protection panel 4 is locked in the closed position, and only the door body 2 can slide.
A notch portion serving as a pull-out means for the guide roller 13 to come out of the guide rail 14 at a position facing the guide roller 13 that is located when the door body 2 is fully closed, 14d is formed, and by pulling out the guide roller 13 from the notch portion 14d in a state where the door body 2 is in the fully closed posture, the protection panel 4 is opened from the closed posture to the vertical posture using the vertical support shaft 8 as a support shaft. It is designed to be unlocked so that it can be transformed into a rocking shape. The guide roller 13 and the guide rail 14 correspond to the opening / closing movement means of the present invention.

  Reference numeral 16 denotes a cap (corresponding to the “locking means” of the present invention) that covers the notch portion 14d. The cap 16 has a rectangular main body portion 16a and the upper end of the main body portion 16a in the door body 2 direction. A projecting portion 16b projecting toward the top and a knob 16c extending upward from the tip of the projecting portion 16b in a substantially L shape. 16d and 16e are perforated, and the fasteners 17 and 17a fixed to the guide rail 14 pass through the long holes 16d and 16e so as to be movable in the vertical direction while being secured from the long holes 16d and 16e. Thus, the cap 16 is movable up and down so that the notch 14d can be opened and closed. The fasteners 17 and 17 a are fixed to the guide rail 14 at a position above the upper end of the guide roller 13.

  When the protective panel 4 is in the closed posture and only the door body 2 is slid, the protruding portion 16b is in contact with the protruding portion 14b of the guide rail 14 from above and the cap 16 is lowered. That is, by setting the fasteners 17 and 17a to be positioned at the upper ends of the long holes 16d and 16e, the notch portion 14d of the guide rail 14 is covered with the cap 16, and in this state, the door body 2 is Even if the protective panel 4 is opened in the fully closed posture, the cap 16 closes the notch, so that the guide roller 13 does not come out of the notch 14d of the guide rail 14. The opening operation can be in a restricted locked state. That is, the cap 16 serves as a locking means for the protective panel 4. Furthermore, a convex portion 16 f is provided on the back surface (side surface of the door body 2) of the cap 16, and the step between the notched portion 14 d and the cap 16 is caused by fitting the convex portion 16 f into the notched portion 14 d. The guide roller 13 is configured to be able to roll smoothly.

Next, the case where the protection panel 4 is opened, that is, the case where the protection panel 4 is changed from the closed position to the open position while the door body 2 is in the fully closed position will be described.
First, when the knob 16c is picked and the cap 16 as a locking means is lifted and slid so that the fasteners 17 and 17a are positioned at the lower ends of the long holes 16d and 16e of the cap 16, the notch portion of the guide rail 14 is obtained. 14d opens. The elongated holes 16d and 16e are slightly narrower in the middle in the vertical direction so that when the cap 16 is lifted, it can be temporarily held in the lifted position to maintain the notch 14d in the open position. It has become.
Then, the guide roller 13 can be faced from the opened cutout portion 14d in a state where the door body 2 is in the fully closed posture. When the protective panel 4 is pulled indoors in this state, the guide roller 13 is cut out. 14d, the protective panel 4 swings from the closed position to the open position, and the protective panel 4 functions as a hinged door.

A guide roller 13 is attached to the side through a bracket, and a guide rail 14 provided on the upper and lower flange 2a of the door body 2 is configured so that the guide roller 13 rolls, so that an existing door pocket can be installed on one side. Even if it is only the sliding door type door apparatus which has only in, the protection panel 4 provided with the function of the door pocket on the other side can be attached easily.
Moreover, since the attached protective panel 4 is attached to the door-side vertical frame 1b and the door body 2, there is no need to provide a pit hole on the floor as in the case of a French lock. .
Normally, since the cap 16 covers the notch 14d and the guard roller 4 is locked from opening so that the guide roller 13 does not come out of the notch, the protection panel 4 moves. In addition, only the door body 2 can be opened and closed.

  When opening such a protective panel 4 by cleaning the inside of the door pocket or the like, the guide roller 13 is positioned at the notch 14d position by bringing the door body 2 into the fully closed posture and lifting the cap 16. In this state, when the protective panel 4 is pulled in the indoor direction, the guide roller 13 is pulled out from the notch 14d, and the protective panel 4 can be opened as an opening door. The side of the door body of the panel 4 can be cleaned.

  And in this thing, although the notch part 14d for extracting the guide roller 13 is provided in the guide rail 14, this convex part 16f provided in the back surface of the cap 16 fits into this notch part 14d. Thus, the rail surface of the guide rail 14 becomes flat, and the door body 2 can be smoothly slid and moved without causing any trouble during the sliding movement of the door body 2 at the normal time.

  Further, in this case, even if the protective panel 4 is retrofitted, the protective panel 4 is attached not to the upper frame 1a but to the eaves 2a and the support member 5, so that an automatic opening / closing mechanism accommodated in the upper frame 1a When performing maintenance of M, it is not necessary to remove various members such as the protective panel 4, the support member 5, the guide roller 13, and the guide rail 14, and the automatic opening / closing mechanism M is exposed only by removing the cover plate 1e of the upper frame. Therefore, maintenance work can be easily performed.

In addition, this invention is not limited to said 1st embodiment, The locking mechanism of the protection panel 4 can also be made like 2nd embodiment shown to FIG.
