  In the conventional elevator entrance / exit device, the elastic resin plate that closes the handle operation hole provided in the door of the screen manual closing device from the back side is fixed with a gap or the like so as to be easily elastically deformed. Therefore, the design was poor and the workability was also poor. Further, when the elastic resin plate is removed due to mischief or the like, there is a risk of dropping and losing.

  The present invention has been made to solve the above-described problems, and even if the closing plate that closes the handle operating hole of the screen manual closing device is removed, it is not lost, and maintainability is improved and design is also improved. It is an object of the present invention to provide an elevator hall entrance / exit device.

  The elevator entrance / exit device according to the present invention is installed in a smoke shielding / flame shielding screen device storing smoke shielding / flame shielding screens that are pulled down from a stored state in the event of a fire to close the entrance / exit and a vertical frame of the entrance / exit The screen manual closing device for manually operating the smoke shielding / flame shielding screen device, the handle operating hole provided in the door of the screen manual closing device, and the handle operating hole are arranged so as to close from the back side. A T-shaped blocking plate with a notch formed on the back of the door of the screen manual closing device and on both sides of the handle operating hole, and the lower surfaces of the protruding parts on both sides of the T-shape of the closing plate are mounted. A pair of left and right fixed bodies for holding the closing plate in place and projecting from the back of the door of the screen manual closing device and below the handle operating hole. At the same time, it is mounted on the guide guide that hooks the protruding parts on both sides of the upper part of the closing plate and the pair of left and right fixed bodies when the closing plate is pushed and removed, and presses the closing plate against the back of the door around the handle operating hole A presser body is provided.

  According to this invention, even when the closing plate is pushed and removed, the upper end portion of the closing plate is not caught and dropped by the guide guide, so that the closing plate is not lost, and maintainability is improved. improves. In addition, even if it comes off, it can be easily restored by inserting it between the resin clip and the back surface of the door and pressing it again, so that maintainability is improved. Moreover, there is no gap between the door and the closing plate, and the design is improved. Further, since the door of the screen manual closing device cannot be opened unless the closing plate is pushed out, mischief other than at the time of a fire can be suppressed.

Embodiment 1.
1 is a front view of a landing side showing an elevator entrance / exit device according to Embodiment 1 of the present invention, FIG. 2 is a perspective view showing a handwheel handle for operating a screen manual closing device, and FIG. 3 is a line AA in FIG. 4 is a front view of the screen manual closing device installed in the vertical frame of the elevator landing doorway device according to Embodiment 1 of the present invention, and FIG. 5 is provided at the door of the screen manual closing device. FIG. 6 is a cross-sectional view taken along line BB in FIG. 5, FIG. 7 is a cross-sectional view taken along line CC in FIG. 5, and FIG. FIG. 9 is a front view of the closing plate for closing the hole from the back side, and FIG. 9 is a view corresponding to FIG. 5 showing a state where the closing plate is pushed and removed.

  In the figure, 1 is a landing door, 2 is a curtain plate constituting the upper front part of the landing three-way frame, 3 is a vertical frame constituting the left and right sides of the landing three-way frame, 4 is installed on the back side of the curtain plate 2 The smoke shield / flame screen device 5 is a guide frame provided in the vertical frame 3, and the smoke shield / flame screen 6 housed in the smoke shield / flame screen device 4 is lowered in the event of a building fire. Guided. Reference numeral 7 denotes a screen manual closing device which is installed in the vertical frame 3 and manually operates the smoke shielding / flame shielding screen device 4. Reference numeral 8 denotes a handle made of a release bar for manually operating the screen manual closing device 7. . When the lever with a wire is pulled with this release rod 8, the screen is unlocked and the shutter is lowered by its own weight. 9 is a manual closing wire, 10 is a building wall, 13 is a door of a screen manual closing device, 14 is a handle operating hole provided in the center of the door 13, and 19 is arranged to close the handle operating hole 14 from the back side. T-shaped blocking plate made of, for example, an elastic resin plate, 19a is a pair of left and right cutouts provided at the lower left and right sides of the blocking plate 19, and 17 is the back surface of the door 13 and the handle operating hole 14 A fixed body consisting of a pair of left and right fixing bolts standing upright on both sides, and a lower end portion having both cutout portions 19a of the closing plate 19 on both sides is inserted between the left and right fixing bolts 17 to form a T-shaped upper portion. The closing plate 19 is held at a predetermined height position by placing the lower surfaces of the protruding portions on both sides. Reference numeral 21 denotes a presser body made of a resin clip or the like inserted into the distal end portion of the fixing bolt 17. By pressing with the resin clip 21, the closing plate 19 can be brought into close contact with the back surface of the door 13 around the handle operation hole 14. Reference numeral 20 denotes a guide guide provided on the back surface of the door 13 so as to protrude below the handle operation hole 14. The inner width dimension of the guide guide 20 is smaller than the width dimension of the upper end portion of the T-shaped blocking plate 19 and larger than the width dimension of the lower end portion where the notch portion 19a is provided. Therefore, when the closing plate 19 is normally mounted, as shown in FIG. 5, the lower end portion of the T-shaped closing plate 19 is fixed in the inserted state. When the closing plate 19 is pushed and removed, as shown in FIG. 9, the upper end portion of the T-shaped closing plate 19 is caught by the guide guide 20 and does not fall.

  Therefore, according to the elevator landing doorway apparatus according to the first embodiment, when the closing plate 19 is pushed and removed, the upper end portion of the T-shaped closing plate 19 is guided by the guide guide 20 as shown in FIG. Therefore, the closing plate is not lost and the maintainability is improved. Moreover, even if it comes off, it is easily restored by inserting it between the resin clip 21 and the back surface of the door 13 and pressing the resin clip 21, so that maintainability is improved. Further, there is no gap between the door 13 and the closing plate 19 and the design is improved. Further, since the door 13 of the screen manual closing device 7 cannot be opened unless the closing plate 19 is pushed out, mischief other than at the time of a fire can be suppressed.
