Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an elevator door guiding device, and more particularly to an improvement in a lower guiding device for a horizontally swinging door that opens and closes an elevator heel or a landing entrance.

[Background of the invention]

Conventionally, elevator doors are opened and closed by having an upper part guided by a door rail and a hanger roller, and a lower part guided by a guide shoe consisting of a small piece or a small roller and a groove provided in a sill. Figure 1.2 shows a guide device for a double door. A pair of roller rollers 2 are each attached to the upper ends of the left and right doors l, and are suspended and run on a door rail 3. In addition, at the bottom, corresponding to the bottom surface of door 1, there is m5 on the top surface of sill 4.
A guide shoe 6 attached to the lower end of the door 1 is fitted into the #45 of the door 1 to guide travel. Further, FIGS. 3 to 5 show a guide device for a single door.

Since this device consists of a high-speed door 7 and a low-speed door 8,
In particular, the lower guide mechanism forms two ties 5 on the upper surface of the sill 4.

However, in the conventional elevator door guide device described above, since the W45 is particularly formed on the upper surface of the sill 4,
Dust and pebbles may get between the guide shoe 6 and the groove 5,
There is a problem in that the doors 1, 7, and 8 cannot be moved. In other words, in the case of a double door, the door 1 will not close in the center, and in the case of a single door, the low speed door 8 will stop in the middle of the entrance width, so there is no problem, but the high speed door 7 closes the entrance width as a running range, so the groove 5 Pebbles that have entered the door become an obstacle to closing the door. For this reason, the elevator often stops because the door is not closed.

[Purpose of the invention]

The present invention has focused on the above-mentioned conventional problems, and aims to provide an elevator-door guide device that does not cause running obstruction by eliminating the groove on the upper surface of the sill at the entrance/exit where dirt and pebbles can easily enter. .

[Summary of the invention]

In order to achieve the above object, an elevator according to the present invention -
The door guide device includes a guide shoe provided at the bottom of the elevator door, and a sill for guiding the guide shoe. It was constructed with grooves facing downward.

With this configuration, the groove that guides the guide shoe when running is oriented downward, preventing dirt and pebbles from getting in and causing trouble when running, so that proper guiding function can be achieved.

[Embodiments of the invention]

Embodiments of the elevator door guide device according to the present invention will be described in detail below with reference to the drawings.

Figures 6 and 7 show an example of application to a double-swing elevator door. As shown in the figure, the upper part of each double door 1 is guided by a combination of a hanger roller 2 and a door rail 3, but the lower part is guided by the lower surface of the sill 4.

That is, the sill 4 corresponds to the lower end surface of each door 1.
The C channel member 10 is attached to the lower surface of the C channel member 10 by a port 11. C
The channel member 1o extends along the traveling direction of the door 1, and is attached so that the opening surface of the groove 12 faces downward. On the other hand, a bracket 13 is fixed to the lower part of each door 1. This bracket 13 is made of a thin steel plate with high strength, and extends from the lower end of the door 1 through the side surface of the sill 4 to below the C channel member 10. A guide shoe 14 that fits into the bracket 6q12 is attached to the bracket 13. The guide shoe 14 is fitted upward into the groove 12 of the small roller, which has a downward opening.

Further, FIG. 8 shows an example in which the monument 12 is formed directly on the sill 4. In such a case, the C channel member 1° becomes unnecessary, and the sill 4 is formed with a thick wall.

According to such an embodiment, the groove 1 for guiding the lower part of the door 1
2 is formed on the lower surface of the sill 4 and has a downward opening, so that it is possible to reliably prevent dirt and pebbles from entering the sill 12.

Therefore, even when both doors 1 are closed, there is no possibility that they will not close at the center. In particular, the groove 12 shown in FIG.
According to the formation example, there is an advantage that the number of parts can be reduced.

Next, Figures 9 to 11 show an example in which the present invention is applied to a single-swing door. In this embodiment, since the high-speed door 7 is particularly problematic, a bracket 13 is attached to the lower part of the high-speed door 7.
A guide shoe 14 is arranged so as to face the lower surface of the sill 4. Then, a C channel member 10 is fixed to the lower surface of the sill 4 over the traveling range of the high-speed door 7, and the groove 12 is fixed to the lower surface of the sill 4.
The guide shoe 14 may be fitted into the hole.

In this example as well, the groove 12 can be formed directly on the lower surface of the pad R4 as shown in FIG.

It goes without saying that this embodiment can also prevent damage to the vehicle caused by the pebbles 6 of the high-speed door.

Although each of the above embodiments has been described with reference to a guide device for a landing door, the present invention can also be applied to a car side door.

It goes without saying that the present invention can also be applied to high-speed doors with three or four door structures.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to provide an elevator-door guide device that can eliminate the groove on the upper surface of the sill and perform proper guiding action while preventing the entry of pebbles and the like.
