BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator sill gap shielding apparatus, and more particularly to an elevator sill gap shielding apparatus suitable for use in an elevator door closing device.

[0002]

2. Description of the Related Art Generally, a gap is provided between an elevator hall sill and a car sill. Therefore, if an object falls from this gap or the wheels of a trolley or the like are small, they may enter the gap, and especially the front wheel of the wheelchair may fall into the gap. In view of this, there has been conventionally proposed a device that opens and closes doors in the hall at the same time as opening and closing the sill between the sills, and that has a structure in which the gap between the sills is always eliminated when the doors are open.

FIG. 9 shows an example of such an example.
It is a block diagram which shows the conventional sill gap shielding apparatus for elevators shown by 0-104576 gazette. 10 is a sectional view taken along the line II of FIG. 9, and FIG. 11 is II-II of FIG.
FIG. 12 is a plan view taken along a line section, FIG. 12 is a configuration view showing a fully opened state of an elevator door, that is, a car door and a landing door in FIG. 9, and FIG. 13 is a cross sectional view taken along line III-III in FIG. Is. In the figure, 1 is an elevator car, 2 is a car sill, 3 is a hall sill, 4 is a car door, 5 is a landing door,
6 is a shield plate provided on the sill 2 of the car through the rotating shaft 7, 8 and 9 are link assemblies and leaf springs respectively attached to the rotating shaft 7, 10 is a door shoe provided on the door 4 of the car, and 11 is a car. It is a spring stretched between the threshold 2 and one end of the shield plate 6.

Next, the operation will be described. Now, when the car door 4 is opened, the leaf spring 9 is pushed down by the door shoe 10 provided on the car door 4, the rotary shaft 7 is rotated by the link assembly 8, and the shield plate 6 is made to elastic force of the spring 11. It rotates against and protrudes from below between the sill 2 of the car and the sill 3 of the landing.

[0005]

The conventional elevator sill gap shielding device is constructed as described above, the shielding plate 6 is projected from the lower side, and the fulcrum of the rotary shaft 7 is 2 points.
Since the shield plate 6 is located at a certain place, if a large load is applied to the shield plate 6, the shield plate 6 will be lowered, and moreover, the shield plate 6
Since the car door 4 does not stick out unless the car door 4 is fully opened, there is a risk that the user may come into contact with the shielding plate 6 when the user goes in and out during the opening / closing operation.

The present invention has been made to solve such a problem, and even if a large load is applied to a shield plate that shields a gap between a sill of a hall and a sill of a car, the shield plate is placed on the lower side. It is an object of the present invention to provide an elevator sill gap shielding device that does not come down and does not come into contact with a user who goes in and out of the shielding plate when opening and closing a door.

SUMMARY OF THE INVENTION An elevator sill clearance shield apparatus according to the present invention is provided for an elevator hall sill,
A step is provided at a position facing the sill of the elevator car, and a shield plate is selectively placed between the sill of the hall and the sill of the car according to opening and closing of the elevator door, and the door of the elevator hall. And a driving means for rotating and driving the shield plate with one side as a fulcrum according to the opening and closing of the door of this hall, and the shield plate is provided between the sill of the hall and the sill of the car when the elevator door is opened. The gap is blocked and a part of the gap is stored in the stepped portion. The driving means includes a lever connected to the door of the landing, a lever shaft that rotates in conjunction with the lever, a cam having a predetermined shape attached to the lever shaft, and one end of which is connected to the shield plate via the shaft. The cam has a connecting rod that is connected to the other end and abuts on the cam to rotate the shield plate. The cam has a tapered portion at the abutting portion.

[0008]

In the present invention, since the shield plate is rotated from the upper side to the lower side and is received by the stepped portion of the threshold of the hall, even if a larger load is applied to the shield plate than the upper portion, it causes the shield plate to move. It does not fall to the lower side. Also, since the cam has a tapered shape, the rotation position of the shielding plate can be changed according to the opening and closing range of the door at the hall, and when the door at the hall opens and the width of the entrance and exit for users, the shielding plate is opened. Since the car descends downward and its upper part is located at substantially the same position as the sill of the car and the upper part of the sill of the landing, the user does not come into contact with the shielding plate even when entering or leaving the car of the elevator.

Sectional drawing, FIG. 5 is a configuration diagram showing a fully opened state of the elevator car in FIG. 1, FIG. 6 is a plan view showing a fully opened state by a shield plate drive mechanism, and FIG. 7 is a side view showing a fully opened state by a shield plate drive mechanism. 8 and 9 are configuration diagrams showing a half-opened state of the elevator car in FIG. In the figure, 3A is the threshold of the hall, and the threshold of this hall 3
A has a step portion 35 (see FIGS. 4 and 7) that receives a part of the bottom portion of the shield plate 6 when the shield plate 6 is rotated downward and becomes substantially flat, as will be described later. 21 is a shield plate 6
Is a hinge for attaching to the sill 3A of the landing, 22 is a connecting rod attachment plate attached to one end of the shield plate 6, 23 is a twist spring provided on the other end of the shield plate 6, and this twist spring 23 is one of them. The side is loaded on the pinhole spring pressing plate 24 attached to the sill 3A of the hall.

Reference numeral 25 is a lever mounting plate mounted on the door 5 of the hall, and 26 is a lever mounted on the lever mounting plate 25. 27 is a drive mechanism plate provided at one end of the sill 3A of the hall, 28 is a lever shaft provided on the drive mechanism plate 27, and the lever 26 is attached to the drive mechanism plate 27 via the lever shaft 28. Reference numeral 29 denotes a tapered cam fixed to the lever shaft 28. Reference numeral 30 is a support plate provided on the drive mechanism plate 27, 31 is a connecting rod, and 32 is a support shaft provided on the supporting plate 30, and the support shaft 32 supports the connecting rod 31. Reference numeral 33 is a roller provided on one side of the connecting rod 31 and adapted to come into contact with the cam 29.
Reference numeral 4 denotes a shaft provided on the other side of the connecting rod 31, and the other side of the connecting rod 31 is attached to the connecting rod mounting plate 22 via the shaft 34.

Next, the operation will be described. Now, when the landing door 5 is opened, the lever 26 moves, and the lever shaft 28 of the drive mechanism plate 27 rotates accordingly. The rotation of the lever shaft 28 causes the cam 29 to also rotate. Cam 29
Has a tapered shape, the connecting rod 31 moves forward along the taper of the cam 29, and the shielding plate 6 is rotated downward via the connecting rod mounting plate 22. As a result, as shown in FIG. 7, the gap between the car sill 2 and the landing sill 3A is shielded by the shield plate 6. At this time, since a part of the bottom of the shield plate 6 is substantially received by the step portion 35 of the threshold 3A of the hall, that is, stored, even if a large load is applied from above, the shield plate 6 is no longer in contact. Does not go down. Then, when the door 5 at the landing is closed, the shield plate 6 returns to the original position by the force of the twist spring 23.

As described above, in this embodiment, the shield plate 6 is attached to the front side of the sill 3A of the hall, and is rotated downward from the upper side to be received by the step portion 35 of the sill 3A of the hall.
Even if a load larger than that of the upper portion is applied, the shield plate 6 will not be lowered further downward. Also,
Since the cam 29 has a tapered shape, the rotational position of the shielding plate 6 can be changed according to the opening / closing range of the door 5 at the hall. For this reason, when the door 5 of the landing is open and the doorway width allows people to enter and exit, the shielding plate 6 descends to the lower side and its upper part is located at substantially the same position as the car sill 2 and the upper part of the landing sill 3A. Therefore, even if the user goes in and out of the elevator car 1, it does not come into contact with the shield plate 6.
