[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevator entrance / exit device including a sill gap closing mechanism that closes a sill gap between a platform sill and a car sill, and in particular, by providing a sill groove on a lower surface or a side surface of the sill, The present invention relates to an elevator entrance / exit device that can be completely closed to a surface without being uneven.
[0002]
[Prior art]
The sill gap between the elevator platform sill and the car sill is generally opened with a width of about 30 mm. This is provided both as a space for disposing the door engagement device and an interval for preventing interference with the landing when the car is shaken. Here, the door engaging device is a device that couples the car door and the landing door by mechanical engagement. By providing the engaging device, the door of the landing is simultaneously opened and closed when the car door opens and closes. If one door drive device is provided on the car side, two sets of doors can be opened and closed at the same time, thereby reducing costs.
[0003]
In this sill gap, the wheel of the wheelchair or the wheel of the carriage may be caught when getting on and off the elevator, or the heel of the high heel or the cane may be caught. For this reason, various sill gap closing devices have been proposed in order to close the sill gap.
[0004]
For example, a closing body provided so as to be able to protrude and retract from the retreat position retracted under the car floor toward the sill gap is connected to a connecting mechanism extending from a door driving device, and linked to the opening and closing operation of the door. Has been proposed (see, for example, Patent Document 1).

[Problems to be solved by the invention]
However, such a conventional sill gap closing device can close the sill gap between the landing sill and the car sill, but the sill gap formed on the upper surface of the landing sill or the upper surface of the car sill. Since it was impossible to fill the formed sill groove, it was not possible to make the floor completely free of unevenness at the entrance of the car. In other words, even if the sill gap can be closed, the sill groove still exists, so there remains a problem that the heel of the wheel and the high heel is caught. Since an impact is generated when the concave portion is reached and an uncomfortable feeling is felt, improvement has been demanded.
[0007]
The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide an elevator entrance / exit device that can be completely closed without unevenness from a car floor surface to a landing floor surface. .

Next, the operation will be described with reference to FIGS. FIG. 5 is an operation flowchart showing the door opening operation. In FIG. 5, the operation of the elevator is started (step S00), and when a door opening command is generated, the door opening operation is started (step S01). When the door leg 12 moves to a predetermined position, the door open position detection sensor 26 detects this. Then, the drive roller 22 rotates and advances the closing body 21 (step S03). When it is confirmed by the closing body position detection switch 25 that the closing body 21 has reached the closing position (step S04), the drive roller 22 stops the closing body 21 (step S05). In the present embodiment, the timing at which the doors 3 and 11 are completely opened and the timing at which the closing body 21 reaches the closing position are adjusted to be the same. Then, the passenger waits until the doors 3 and 11 are completely opened, that is, fully opened, and then gets on and off (step S06).
[0020]
FIG. 6 is an operation flowchart showing the door closing operation. In FIG. 6, the operation of the elevator is started (step S10), and when a door closing command is generated, the door closing operation is started (step S11). When the door leg 12 moves to a predetermined position, the door open position detection sensor 26 detects this. Then, the driving roller 22 rotates and retracts the closing body 21 (step S13). When it is confirmed by the closing body position detection switch 25 that the closing body 21 has reached the retracted position (step S14), the drive roller 22 stops the closing body 21 (step S15). When the car door 11 and the landing door 3 are completely closed, the elevator preparation is completed (step S16).
[0021]
As described above, the elevator doorway apparatus according to the present embodiment includes the car door leg 12, the car sill 9, the landing door leg 4, the landing sill 2, and the sill gap closing mechanism 20. The car door leg 12 has a car door leg 12 having a vertical part 12a extending downward from the lower end of the car door 11 and a horizontal part 12b extending substantially horizontally from the lower part of the vertical part 12a. Yes. In addition, the car sill 9 extends in the door opening / closing direction at the landing side end of the car floor 8 and is recessed, and has an opening facing directly downward in cross section, and includes a sliding portion 12c at the tip of the leg 12 of the car door. It has a car sill groove 9a for storing and guiding it.
[0022]
The landing door leg 4 includes a landing door leg 4 having a vertical portion 4a extending downward from the lower end of the landing door 3 and a horizontal portion 4b extending substantially horizontally from the lower portion of the vertical portion 4a. Yes. The landing sill 2 extends in a door opening / closing direction at the end of the hoistway side of the landing 1 and has an opening facing downward in the cross section, and houses the sliding portion 4c at the tip of the landing door leg 4. And has a landing threshold groove 2a for guiding it.
[0023]
Further, the sill gap closing mechanism 20 is provided so as to be capable of moving forward and backward with respect to the sill gap D, and a closing body 21 that moves between a closed position that closes the sill gap D and a retracted position that retreats under the car floor, And a drive roller (blocking body driving device) 22 that moves 21 between a closed position and a retracted position. The closed body 21 has a threshold gap D formed between the landing threshold 2 and the car threshold 9. Close and fill without any gaps.
[0024]
With the above configuration, the landing sill groove 2 a is formed to face downward from the front end of the landing sill 2, and the car sill groove 9 a faces downward from the front end of the car sill 9. In addition, since the closing body 21 fills and closes the sill gap D between the front end portion of the landing sill 2 and the front end portion of the car sill 9 without any gap, it closes from the car floor surface 8a to the landing floor surface 1a. It can be completely closed without unevenness. Therefore, the problem that the heel of the wheel or the high heel is caught is solved.
[0025]
Further, the closing body 21 closes and closes the sill gap D with a horizontal surface portion 21d which is the same horizontal surface as the car floor surface 8a and the landing floor surface 1a at the closing position. Therefore, when a wheelchair or a carriage moves on this, it can move smoothly, so it is possible to get on and off comfortably.
[0026]
Further, the door opening position detection sensor 26 (door opening position detector) for detecting the opening position of the landing door 3 is further provided. When the door is opened, the closing body 21 is moved to the closing position, and when the landing door 3 and the car door 1 are closed to a predetermined interval, the closing body 21 is moved to the retracted position. Therefore, the reliability of operation | movement improves, without the door 3 of a landing, the door 1 of a car, and the obstruction | occlusion body 21 interfering with each other. Further, by providing the door opening position detection sensor 26, the timing at which the doors 3 and 11 finish opening (fully open) and the timing at which the closing body 21 reaches the closing position can be adjusted to be the same. However, when waiting for the doors 3 and 11 to finish opening, the siding gap D is already closed, and the passenger can get on and off comfortably without feeling uncomfortable.
Needless to say, the timing at which the closing body 21 reaches the closing position may be before the doors 3 and 11 are fully opened.
[0027]
Furthermore, the length of the closing body 21 in the door opening / closing direction is substantially the same as the doorway width of the car. Therefore, the obstruction body 21 can be made the minimum necessary, and the apparatus can be made compact and inexpensive.
[0028]
The car sill groove 9a according to the present embodiment is formed in the car sill 9 with the opening facing downward. On the other hand, the leg 12 of the car door is formed by being bent in a bowl shape. However, the car sill groove 9a is formed in the vertical surface of the tip of the car sill 9 with the opening horizontally oriented, while the car door leg 12 is bent into an L-shaped cross section so as to engage with it. Even if the landing threshold groove 2a on the landing 1 side and the landing door leg 4 are formed in the same manner, the forward / backward movement of the closing body 21 is retreated below the car floor as viewed from the side, for example. The same effect can be obtained by bending and moving forward and backward from the retracted position toward the sill gap D and finally closing the sill gap D in the vertical direction.
[0029]
Further, the elevator of the present embodiment is an elevator in which a car door 11 and a landing door 3 are provided in both the car 7 and the landing 1, respectively. However, the doorway apparatus of the present invention has only the car door 11. It is also applicable to an elevator that is provided and does not have a landing door 3 at the landing 1, and in this case, the landing door 3 and the landing threshold 2 are omitted from the present embodiment.
[0030]
Further, the door open position detection sensor 26 as the door open position detector of the present embodiment detects the position of the leg 12 of the car door. As the door open position detector, Any door can be used as long as it can detect that any of the doors at the landing is opened at a predetermined interval. For example, the position of the door body may be detected without being limited to the position of the leg 12 of the car door.
[0031]
