As the driving device 6 rotates forward and reverse, the left and right doors 5, 5 slide to open and close along the closing doors 9, 9 via the belts 7, 7 and pulleys 8, 8.

Here, when transporting large items in and out, or when an emergency such as a fire occurs, etc.
When a larger opening than the door 5 is required, as shown in FIG. 3, when the door 5 is pushed outward, the engaging portions 14, 14 of the door 5 with the hanging frame 4 are disengaged, and the swing fulcrum portion 10, 10 as the center, and the sliding door 9 is also pushed out by the swing of the door 5, and swings around the upper and lower swing fulcrums 11, 11, 12, 12. Even when the doors 5, 5 remain open, they slide to the positions of the pillars 13, 13 on both sides, and a frontage twice as large as usual is obtained.

However, with such doors that can be opened and closed by either sliding or swinging, in the event of an emergency such as a fire, or when carrying in and out large items,
Even a person without special training needs to be able to easily operate the operating device by operating the opening operation part provided on the door surface, so that the door can be opened and closed together with the closing door by swinging.

The present invention was developed with the aim of satisfying the above-mentioned conditions, and includes an operating device that is operated when the door is opened by swinging, and an opening operation that is provided on the front of the door and that operates the operating device. It is equipped with a section. With this configuration, disasters can be minimized by quickly turning off the power, releasing steady rests and locks, and emergency indicator lights, etc., and making it possible to easily transport large items in and out. .

Hereinafter, one embodiment of the present invention will be described based on the drawings from FIG. 4 onwards. Note that the same parts as in FIGS. 1 to 3 are given the same reference numerals.

In FIG. 4, 15 is a frame of the door 5, 4 is the hanging frame, and 16 is a lower rail on the floor.

A touch plate 17 serving as an opening operation section is provided at a substantially middle position of the stile 15 facing the indoor side. The pressing surface 18 of the touch plate 17 may protrude slightly from the stile 15, be substantially flat with the surface of the stile 15, or may be slightly convex. Further, the pressing surface 18 may remain exposed to the outside, but as shown in FIG. 5, it may be covered with a transparent protection plate 19 that can be easily destroyed.

At the upper end of the back of the touch plate 17, arms 21, 22, and 23, which are rotatable about a shaft 20, are integrally provided. Among these, the arm 21 is fixed to the touch plate 17, and the arm 22 is attached to the tip of the touch plate 17. An attraction coil spring 25 is connected to the arm 24, and a connecting rod 27 is rotatably connected to the tip 26 of the arm 23. The base end 28 and the distal end 24 of the spring 25 are
When the line connecting the two is on the right side of the shaft 20, the connecting rod 27 is urged downward.

At both upper and lower ends of the connecting rod 27, upper and lower steady rests 29 and 30 are provided as operating devices. The upper steady rest 29 is rotatably connected to a crank 32 supported by a pin 31 in order to change the upward movement and downward movement, and the other end of the crank 32 is connected to the connecting rod 27. Connected for rotation. In addition, the upper end of the upper steady rest 29 is connected to the hanging frame 4.
