Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator landing door device, and particularly to an elevator landing door device with an improved hanging structure of the landing door.

[Conventional technology]

As described in Japanese Utility Model Application Publication No. 55-89763, the conventional device was designed to be applied to mass-produced headers and landing doors by inserting an intermediate member between the landing door and the door hanger that suspends it. . A header bracket 2 and a door rail 3 fixed to the building wall 1 (back side of the landing on the building side), a header 4 that supports the door rail 3, and a door hanger 7 that pivotally supports a rotating roller 6 that rolls on the door rail 3 are used to secure the landing. A U-shaped intermediate member 9 is inserted between the door hanger 7 and the landing door 5, and the door hanger 7 is fixed on one side of the U-shape, and the landing door 5 is fixed on the other side with bolts. . 8 is an entrance/exit frame.

[Problem to be solved by the invention]

With the above conventional technology, there is a problem that the building wall must be folded due to building errors in order to make the gap between the landing door 5 and the entrance frame 8 a predetermined value during installation work. The shortcoming was that it did not shorten the construction period as expected.

An object of the present invention is to provide an elevator landing door device that can shorten the construction period.

[Means to solve the problem]

The above object is achieved by locating the vertical portion of the door hanger closer to the hoistway than the landing door, and by connecting the lower end of the door hanger and the upper part of the landing door with a substantially Z-shaped intermediate member.

[Effect]

By installing a substantially Z-shaped intermediate member between the door hanger and the landing door, a gap is created between the back of the header and the building wall, eliminating the need for cutting the building, thereby shortening the construction period.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 1, a header bracket 2 fixed to a building wall 1 (back side of the landing on the building side) supports a header 4, a door rail 3 is supported on this header 4, and a rotating roller that rolls on this door rail 3. The landing door 5 is suspended by a lower ahanger 7 which pivotally supports the landing door 5. A feature of the present invention is that a substantially Z-shaped intermediate member 9 is provided between the landing door 5 and the door hanger 7, and the door hanger 7 is bolted to one side of the 7-shape, and the landing door 5 is bolted to the other side of the 7-shape. This is because it is permanently installed. and,
The upper side 9a of this intermediate member 9 is on the hoistway side (left side in the drawing) than the landing door 5 so that the header 4 can be placed without grinding the building wall 1, and the lower side 9b is on the hoistway side (left side in the drawing). It is located at the top (on the right side of the drawing).

In addition, the lower side part 9b is lowered by one step with respect to the upper side part 9a of the intermediate member 9, so that the bolt 11 for fixing to the upper stopper 5a of the fifth landing door 5 is prevented from extending upward and becoming an obstruction. doing. As described above, the intermediate member 9 has a substantially Z-shape, and the center line of fixing it to the door hanger 7 with the bolt 10 and fixing it to the landing door 5 with the bolt 11 is shifted in the lateral direction, so that the center line of the intermediate member 9 is deviated in the horizontal direction. 4, thereby eliminating the need for grinding the building wall 1, preventing interference with the doorway frame 8, and increasing the strength of the intermediate member alone.

〔Effect of the invention〕

According to the present invention, since the vertical part of the door hanger that pivotally supports the rotating roller is located closer to the hoistway than the landing door, a gap can be provided between the back of the header and the building wall, resulting in cutting work. This has the effect of shortening the construction period by eliminating this.
