DETAILED DESCRIPTION OF THE INVENTION
<First Embodiment>
FIG. 1 is a view showing a first embodiment, FIG. 1 (a) is a front view, FIG. 1 (b) is a side sectional view, and the sill closing device is a schematic sill closing plate 1 and a closing plate mounting plate. 4, rod 6, cylinder 8, roller 9, guide 10, and bracket 13.
[0013]
The closing plate mounting plate 4 is formed in the lower part of the floor of the upper car Cu with the same width as the entrance / exit width, and the closing plate mounting plate 4 is mounted on the bottom surface of the car floor 25 of the upper car Cu as follows. In other words, the upper car Cu is attached from the car door 3 side and is rotatably supported by the closing board attaching plate 4 by the shaft 15 attached to the sill closing board 1. In this case, the shaft 15 is disposed at a position shifted to the right from the center of the dimension in the width direction of the closing plate mounting plate 4 as shown in FIG.
[0014]
The cylinder 8 has a slidable shaft 7 which is attached to a bracket 13 fixed to the lower car Cd. One end of a rod 6 is pivotally supported by the sill closing plate 1 so that the sill closing plate 1 can rotate, and the other end of the rod 6 is connected to one end of a shaft 7 of the cylinder 8. A roller 9 is rotatably supported on the other end of the shaft 7 of the cylinder 8.
[0015]
The guide 10 is attached to the car door 3 of the lower car Cd, and the guide 10 is formed with a horizontal plane part and an inclined surface part for moving the roller 9 up and down as the car door 3 opens and closes.
[0016]
In the sill blocker of the first embodiment configured as described above, when the car door 3 of the lower car Cd is opened as shown in FIG. 1, the roller 9 abuts against the horizontal surface of the guide 10, Conversely, when the car door 3 of the lower car Cd is closed, the roller 9 contacts the inclined surface portion of the guide 10. As a result, the roller 9 moves upward when the car door 3 of the lower car Cd is open, and moves downward when the car door 3 is closed. The rod 6 goes down or goes up.
[0017]
Therefore, only when the car door 3 of the lower car Cd is opened as shown in FIG. 1, the sill closing board 1 protrudes and becomes horizontal, so that the sill closing board 1 is the landing door 2 of the upper car Cu. The falling object 18 can be received from the gap with the car door 3 and at the same time, the field of view from the lower car Cd to the upper car Cu can be blocked. In this way, the fallen object 18 from the upper car Mu can be prevented by the sill block plate 1, so that even if the passenger Md enters and leaves the lower car Cd, the fallen object 18 does not fall and hit the head or the like.
[0018]
Further, while the lower car landing door 2 and the car door 3 are open, even when looking up from the lower car, the sill closing plate 1 blocks the view of the gap between the sill 14a and the sill 14b and cannot look up at the passenger Mu.
[0019]
Second Embodiment
FIG. 2 is a view showing the second embodiment, and FIGS. 2A and 2B are a front view and a side view showing only the main part thereof, and the car door 3 is closed in both cases.

[0021]
The switch 16 is disposed close to the sill block 1 and when the sill block 1 is in an inclined state, that is, when the car door 3 is in a closed state, the movable piece does not operate (contact). When the car door 3 is in the horizontal state, that is, when the car door 3 is in the open state, the movable piece operates (contacts). The operation state signal of the switch 16 is input to the elevator control device, and the sill block 1 When the gap between the landing sill 14a and the car sill 14b is closed, safety can be improved by preventing the cars Cu and Cd from moving up and down.
[0022]
The tray 20 can be removed on the base 21 fixed on the bracket 13, and when the sill block 1 is inclined as shown in FIGS. 2 (a) and 2 (b), the sill block 1 is configured such that the fallen object 18 placed on 1 enters the tray 20.
[0023]
In this way, by adopting a configuration in which the fallen object 18 received by the sill block plate 1 or a passenger's fallen object falls into the tray 20, the elevator can be easily cleaned and maintained. In addition, the receiving tray 20 is mounted on the table 21 so that the falling object 18 is received by the sill block plate 1 and is not scattered, and the receiving tray 20 is removable, so that the elevator can be easily cleaned and maintained. it can.
[0024]
The operation of the embodiment of FIG. 2 is the same as that of the above-described embodiment. When the car is landed, when the landing door 2 and the car door 3 of the lower car Cd are opened and passengers enter and leave the lower car Cd, The roller 9, the shaft 7 and the rod 6 are pulled down by the guide 10, and the sill closing plate 1 rotates around the shaft 15, and projects into the gap between the sill 14 a and the sill 14 b.
[0025]
In addition, while the landing door 2 and the car door 3 of the lower car Cd are opened, the sill closing plate 1 protrudes into the gap between the sill 14a and the sill 14b so that the passengers of the lower car Cd cannot look up, and the gap is closed. It is.
[0026]
As a result, it is possible to prevent garbage, rainwater, lost items, etc. from the upper car Cu from falling on the passengers of the lower car, and to look up the passengers of the upper car Cu from the lower car Cd.
[0027]
Further, by changing the inclination angle of the inclined surface portion of the guide 10 that guides the roller 9 in the horizontal direction, the projection timing (rotation timing) of the sill cover plate 1 can be changed, for example, when the car door 3 is fully open or the car door 3 is fully open. Can be adjusted just before.
[0028]
Further, since the weight 11 is attached to the sill block plate 1, the sill block plate 1 is maintained in an inclined state as shown in FIG. 2B, or the state shown in FIG. ) And the reliability can be improved as compared with the embodiment of FIG.
[0029]
