Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an elevator landing entrance/exit device disposed at a landing entrance/exit opening of a hoistway.

[Technical Background of the Invention and Problems Therewith] Generally, a landing entrance/exit device consisting of a sill and a landing frame disposed on the sill is arranged at a landing entrance/exit opening of an elevator hoistway.

As such a conventional elevator hall entrance/exit device, the one shown in FIG. 6 is known.

That is, in this landing entrance/exit device, the recessed stepped portion 2a of the landing entrance/exit opening 2 that opens on the wall surface 1a of the hoistway 1 on the building side.
A sill 3 is provided at the. A landing frame 5 to which a landing door 4 is attached is disposed above both ends of the threshold 3.

As shown in FIG. 7, the above-mentioned sill 3 has 1! between the sill 3 and the recessed step 2a. R6 are inserted alternately from both sides at right angles to the longitudinal direction of the sill 3 to adjust the height of the sill 3.

However, in such a conventional elevator hall entrance/exit device, the height of the sill 3 is adjusted by driving a mold 6 between the sill 3 and the recessed step 2a, so that the sill 3 cannot be installed at a specified position. There was a problem in that it was shifted in the front-back direction, which is not indicated by the arrow in FIG.

Furthermore, when mortar (not shown) is filled between the sill 3 and the recessed step 2a, the moisture in the mortar deforms the mold 6, and as a result, the height of the sill 3 deviates from the predetermined position. There was a problem.

Therefore, as shown in FIG. 8, the height of the sill 3 is adjusted by inserting a metal plate 7 between the sill 3 and the recessed step 2a. In this case, it is necessary to lift the sill 3 and insert the metal plate 7, which makes it difficult to easily adjust the height of the sill 3, and it takes a long time to make these adjustments. .

[Objective of the Invention 1] The present invention has been made in order to solve the above-mentioned conventional difficulties, and provides an elevator landing entrance/exit device that allows fine adjustment of the height and installation position of the sill easily, quickly, and reliably. is intended to provide.

[Summary of the Invention] That is, the elevator landing entrance/exit device of the present invention has a sill disposed in a recessed step formed at the edge of the building floor of the landing entrance opening opening in the wall of the hoistway. , an elevator hall entrance/exit device provided with a landing frame for mounting a landing door, characterized in that the threshold is provided with an adjustment mechanism for finely adjusting the height and horizontal position of the threshold.

[Embodiments of the invention] Embodiments of the present invention will be described in detail below based on the drawings.

1 to 3 show an elevator hall entrance/exit device according to an embodiment of the present invention, in which a concave stepped portion 11 of a hall entrance opening 11 that opens into a building-side wall 10a of a hoistway 10 is shown.
A sill 12 is arranged above a.

A landing frame 14 to which a landing m13 is attached is arranged above both ends of the sill 12. This landing frame 14 is attached to a pair of pillars 14a and 14b by bolts via mounting brackets 15 fixed to the wall surface 10a of the landing entrance/exit opening 11.
It is fixed by a nut 16.

As shown in FIG. 4, the sill 12 described above is provided with a plurality of screw holes 17 at predetermined intervals, and each of these screw holes 17 has an adjustment bolt 18 extending from the top surface to the bottom surface of the sill 12. It is screwed in towards. The tips 18a of these adjustment bolts 18 are in contact with a receiving plate 19 disposed on the recessed step portion 11a, and the adjustment bolts 18 are used to adjust the height of the sill 12 and adjust the mounting position.

The elevator hall entrance/exit row device configured as described above is assembled as described below.

That is, first, the recessed step portion 11a of the landing entrance/exit opening 11
A receiving plate 19 is placed at the. Next, the threshold 12 into which the adjustment bolt 18 is screwed is disposed on the receiving plate 19. and,
Tighten the adjustment bolt 18 and insert its tip 18a into the receiving plate 19.
The height and installation position of the sill 12 are adjusted by bringing it into contact with the sill 12.

Further, when filling mortar (not shown) between the sill 12 and the recessed step portion 11a, the mortar (not shown) is poured at this point.

After that, the landing frame 14 to which the landing door 13 is attached is placed above both ends of the threshold 12, and the pillars 14a, 1 of the landing frame 14 are
4b to the wall surface 10a of the hall entrance/exit opening 11
5 and is fixed with bolts and nuts 16.

In the elevator hall entrance/exit device assembled in this way, a plurality of screw holes 17 are provided in the sill 12 arranged on the recessed step 11a of the hall entrance/exit opening 11, and adjustment bolts are inserted into each of these screw holes 17. 18, the height and installation position of the sill 12 can be adjusted easily, quickly, and reliably. Furthermore, even when mortar (not shown) is filled between the sill 12 and the recessed stepped portion 11a, the height and mounting position of the sill 12 can be reliably maintained at a predetermined position.

In the embodiment described above, adjustment of the height and mounting position of the sill 12 was described, but as shown in FIG. The adjustment bolts 21 are screwed into these screw holes 20, respectively, and the tips 21a of the adjustment bolts 21 are brought into contact with the side wall 11b of the hall entrance/exit opening 11, so that the hall frame 14
Of course, it may also be used to adjust the mounting position of the.

In addition, in the embodiment described above, the threshold 12 and the landing frame 14
Although the present invention has been described with respect to a landing entrance/exit device in which the threshold and the landing frame are separated, it is of course applicable to a landing entrance/exit device in which the sill and the landing frame are integrally formed.

[Effects of the Invention] As described above, according to the elevator hall entrance/exit device of the present invention, an adjustment mechanism for finely adjusting the height and horizontal position of the sill is provided at the sill. Installation allows for fine adjustment of position easily, quickly, and reliably.
