In the figure, 1 is a landing floor, 2 is an entrance provided in the landing floor 1, and a side part and an upper part are surrounded by a three-sided frame 3. Reference numeral 3a denotes an upper frame of the three-way frame 3, reference numeral 4 denotes a hall indicator provided on the upper frame 3a, and a hall door for displaying the elevating and lowering and stopping states of the running car, and numeral 5 denotes a hall door for opening and closing the entrance 2.

FIG. 5 is a front view of a conventional elevator landing door device disclosed in Japanese Utility Model Laid-Open Publication No. 3-41775, as viewed from the hoistway, and FIG. 6 is a sectional view taken along line AA of FIG.
5 and 6, reference numerals 2, 3, 3a and 5 denote the same or corresponding parts as those shown in FIG. 4, reference numeral 6 denotes a hoistway wall surface, and reference numeral 7 denotes a building longitudinal beam fixed to the hoistway wall surface 6. , 8 are horizontal beams provided for fixing the landing door device, and are connected to the building vertical beams 7 by welding. Reference numeral 9 denotes a door hanger provided with a pair of hanger rollers 10 at both ends thereof.

[0004] Reference numeral 11 denotes a hanger case provided with a rail 12 on which the hanger roller 10 rolls. Reference numeral 13 denotes a pair of right and left fixing brackets for fixing the hanger case 11 to the three-sided frame 3. , And supports the hanger case 11. Reference numeral 14 denotes a pair of right and left mounting brackets having an L-shaped cross section for fixing the hanger case 11 to the cross beam 8, one side of which is fixed to the cross beam 8 by bolts 14 a, and two ends of the hanger case 11 on the other standing side. A pair of upper and lower longitudinal slots 14b for attaching the side plate 15 welded to the surface are provided. The side plate 15 is provided with a pair of upper and lower horizontal holes 15a so as to coincide with the positions of the long holes 14b provided in the mounting bracket 14, and the mounting bracket 14 and the side plate 15 are fastened by bolts and nuts 16. It is supposed to.

When the landing door device for an elevator having the above configuration is installed on the landing, mounting brackets 14 are fastened to both left and right ends of the horizontal beam 8 fixed to the building longitudinal beam 7 by bolts 14a. Next, the hanger case 11 with the side plates 15 welded to both ends is moved to a position where the long holes 14b and the long holes 15a coincide with each other, and temporarily fixed with the bolts and nuts 16.
Then, the hanger roller 10 of the door hanger 9 on which the landing door 5 is suspended is placed on the rail 12, the bolts and nuts 16 are loosened, and the front and rear and up and down of the landing door 5 and the like can be changed within the variable range of the long holes 14b and 15b. After the positioning, the bolts and nuts 16 are tightened to fix the mounting bracket 14 and the side plate 15.

[0006]

Since the conventional elevator landing door device is constructed as described above, for example, the landing indicator 4 disposed above the landing side of the three-way frame 3 is changed in specifications after installation. When the hanger case 11 fixed to the cross beam 8 via the mounting bracket 14 must be moved upward due to, for example, the fixing portion of the cross beam 8 welded to the building vertical beam 7 is removed by fusing or the like. There is a problem in installation, which involves a complicated process associated with a change in the specification, in which is moved to a predetermined upper position and welded to the building vertical beam 7 again.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. When it is necessary to move the hanger case upward due to a change in the specification of a landing indicator or the like, welding of the horizontal beam and the building vertical beam is performed. Elevator landing doors that can easily move the hanger case upwards to avoid interference with the landing indicator after specification changes, without having to perform the complicated work of moving the cross beam by removing the joint part by fusing, etc. The aim is to obtain a device.

[0008]

A landing door apparatus for an elevator according to the present invention comprises a pair of vertical building longitudinal beams fixed to inner walls of a hoistway on the left and right sides of an entrance, and a perpendicular to the building vertical beam above the entrance. Horizontal beams, a pair of left and right mounting brackets with one side fixed to the horizontal beams, and side plates fixed at both ends
The hanger which is fixed by contacting the side plate with the mounting bracket
It and a casing, provided with a long hole of a plurality of longitudinal, transverse elongated holes in the side plate provided on the mounting bracket, lateral
Select the longitudinal slot corresponding to the slot of
The position of the hanger case can be adjusted .

[0009]

According to the present invention, even if a change in the specification of a landing indicator that occurs immediately before installation of a landing door device of an elevator, or a landing indicator that changes to another specification after installation, may interfere with a hanger case, A desired longitudinal direction positioned above the longitudinal long holes provided in the mounting bracket, in a plurality of lateral long holes provided in the side plate.
The hanger case can be easily moved upward by selecting the long hole and screw-connecting, thereby avoiding interference between the hall indicator after the specification change and the hanger case.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 is a front view of a landing door device for an elevator according to the present invention viewed from a hoistway side, FIG. 2 is a sectional view taken along line BB of FIG. 1, and FIG. 3 is a state in which the hanger case in FIG. FIG. 5 and 6 showing the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

The mounting bracket 14 shown in FIG. 2 is provided with three longitudinal slots 14b, 14c, and 14d at equal intervals at a pitch L, and an interval corresponding to the center of the slots 14b to 14d. The mounting bracket 14 and the side plate 15 are fastened to each other by bolts and nuts 16 using the long holes 15a at the pitch L provided in the side plate 15 and the long holes 14c and 14d. 11 is held at a predetermined height.

In the elevator hall door device having the above-described structure, the hall indicator 4 and the hanger case 1 are changed just before or after installation by changing the specifications of the hall indicator 4 shown in FIG.
1 may interfere with the mounting bracket 14 and the side plate 1.
Then, the bolts and nuts 16 fixing the nut 5 are released, and the door 5 suspended from the rail 12 is removed.

[0013] Next, as shown in FIG. 3, the hanger case
11 is moved upward, and two long holes 15a of the side plate 15 are moved.
And the elongate holes 14b and 14c of the mounting bracket 14 are aligned with each other, and temporarily fastened by the bolts and nuts 16. Then, the hanger roller 10 pivotally supported by the door hanger 9 is connected to the rail 12.
The door 5 is suspended on the door 5 via the door hanger 9, and the front and rear and up and down positions of the door 5 are positioned while loosening the temporarily fastened bolts and nuts. I do. In this case, the doors 5 and 5 use doors corresponding to the height position of the door hanger 9.

In the above description, the case where there are two fixing positions of the mounting bracket 14 and the side plate 15 has been described. However, the above fixing positions may be two or more depending on the dimensions of the hall indicator 4 in a range where the specification change can be predicted. Elongated holes 14b-14
If d is provided, it is possible to obtain an elevator hall door device that is more responsive to a change in the specification of the hall indicator 4.

[0015]

As described above, according to the present invention, the mounting metal
The tool has a plurality of long holes in the vertical direction, and
Long hole in the vertical direction corresponding to the long hole in the horizontal direction
Select the screw connection and adjust the position of the hanger case
Since the, even if design changes of the hall indicator such as to interfere with the hanger case, without requiring complicated operations such as moving the cross beam fixed by welding to the building vertical beams, simply the hanger case fixed the height position can be obtained landing door device for an elevator which can installed and easily changed.
