DESCRIPTION OF THE PREFERRED EMBODIMENTS A mode for carrying out an elevator hall threshold device according to the present invention will be described below with reference to the drawings. In each figure, the same or similar configurations are denoted by the same reference numerals, and repeated descriptions are omitted.

First, using the schematic cross-sectional view of FIG. 1, the configuration of a general elevator apparatus 10 will be outlined. As shown here, the elevator system 10 includes a car 11, a counterweight 12, and a main rope 13 in a hoistway 21 of a building 20, and a hoist in a machine room 22 of the building 20. 14 is installed. A main rope 13 having one end connected to a car 11 and the other end connected to a counterweight 12 is hoisted by a hoist 14 to move the car 11 to an arbitrary floor.

Further, on the side of the hoistway 21 of the landing 23 of each floor, a landing door 4 is installed that interlocks with the opening and closing of the car door of the car 11 . A lower end of the landing door 4 is slidably supported by a landing threshold device A, which will be described later. In the following, the depth direction of the hoistway 21 is defined as the x direction, the opening/closing direction of the landing door 4 is defined as the y direction, and the elevation direction of the car 11 is defined as the z direction.

Next, the elevator hall threshold device A according to the first embodiment of the present invention will be described with reference to the enlarged sectional view of FIG. As shown here, the elevator hall threshold device A has a hall threshold 1 , a fixture 2 , and a partition plate 3 .

The landing threshold 1 is arranged along the lower edge of the landing opening and guides the opening and closing operation of the landing door 4 .

Although the description is simplified, for example, a plurality of fixtures 2 are arranged along the longitudinal direction of the landing threshold 1 (the opening and closing direction of the landing door 4) on the hoistway wall 5 on the landing opening side, Each of them is fixed to the hoistway wall 5 by a fastener (not shown). A landing threshold 1 is attached to the upper portion of the fixture 2 with fasteners 6 .

The partition plate 3 closes the gap between the landing threshold 1 and the hoistway wall 5 to prevent the mortar 7 used for finishing the landing floor from flowing into the hoistway 21 through the gap. Further, the partition plate 3 of the present embodiment can be used even when the dimensional error of the building in the height direction and the depth direction (that is, the error in the position and shape of the hoistway wall 5) is relatively large. It is devised to easily close the gap between the hoistway walls 5 .

Specifically, the partition plate 3 has a split structure composed of two members, a low-rigidity member 31 and a high-rigidity member 32 .

The low-rigidity member 31 is a member that requires on-site processing when the partition plate 3 is installed, and has a low bending strength that allows an operator to bend it. One end of the low-rigidity member 31 is sandwiched between the landing threshold 1 and the fixture 2, and the other end extends toward the hoistway wall 5 side.

On the other hand, the high-rigidity member 32 is a member that does not require on-site processing when the partition plate 3 is installed, and has a bending strength higher than that of the low-rigidity member 31 . One end side of the high-rigidity member 32 overlaps the other end side of the low-rigidity member 31 , and the other end side is fixed to the upper surface of the hoistway wall 5 .

Further, a long hole 32a long in the x direction is formed in the other end of the high-rigidity member 32, and a fastener 33 (concrete screw or the like) is passed through the long hole 32a, and the upper surface of the hoistway wall 5 is made high. The rigid member 32 is fixed. In order to employ such a fixing method, in this embodiment, the fastener 33 is allowed to be arranged at any position within the range of the long hole 32a. A bent portion 32 b is formed at one end of the high-rigidity member 32 , and the bent portion 32 b overlaps the low-rigidity member 31 .

The high-rigidity member 32 has a relatively large gap between the fixture 2 and the hoistway wall 5, and even if a load is applied to the cantilevered high-rigidity member 32 when boarding, the high-rigidity member 32 is It is preferable to use a high-rigidity plate material such as a steel plate so as to secure the bending strength that does not bend one end of the plate, but the material and thickness may be changed according to the required bending strength. Needless to say. In FIG. 2, the plate thickness of the high-rigidity member 32 is thicker than that of the low-rigidity member 31; can be

Next, the procedure for installing the partition plate 3 will be described with reference to FIG.

First, as shown in FIG. 3A, the high-rigidity member 32 is placed on the upper surface of the hoistway wall 5, and in this state, the high-rigidity member 32 is placed on the hoistway 21 within the range restricted by the long hole 32a. is moved in the depth direction to adjust the position of the high-rigidity member 32 in the depth direction. At this time, the bent portion 32 b of the high-rigidity member 32 is brought into close contact with the side surface of the fixture 2 fixed to the hoistway wall 5 . After completing these adjustments, the fastener 33 is used to fasten and fix the high-rigidity member 32 .

Next, as shown in FIG. 3B, after placing one end side of the flat plate-like low-rigidity member 31 on the upper surface of the fixture 2, the landing threshold 1 is placed on the upper surface of the low-rigidity member 31, and the fastener is 6, the landing threshold 1 and the fixture 2 are fastened together so as to sandwich the low-rigidity member 31. - 特許庁At this time, one end side of the low-rigidity member 31 is prevented from projecting from the side of the landing threshold 1 toward the hoistway 21 and the low-rigidity member 31 and the car 11 do not come into contact with each other.

After that, the operator bends the low-rigidity member 31 as shown in FIG. 3(c). In the example shown in FIG. 3, since the thickness dimension of the floor finish, that is, the thickness dimension T1 of the mortar ₇ is relatively small, the overlapping margin between the low-rigidity member 31 and the high-rigidity member 32 is large. The low-rigidity member 31 can be bent to have a substantially crank-shaped cross section. That is, in the low-rigidity member 31 of FIG. 3, a first bent portion 31a is formed above the bent portion 32b of the high-rigidity member 32, and a second bent portion 31b is formed along the lower end of the bent portion 32b. .

After installing the partition plate 3 for closing the gap between the landing sill 1 and the hoistway wall 5 in this way, the landing sill device A shown in FIG. 2 can be completed by pouring an appropriate amount of mortar 7.

Here, an aspect of the partition plate 3 when the thickness dimension of the floor finish is large will be described with reference to FIG. 4 .

In FIG. 4, the thickness dimension of the floor finish, that is, the thickness dimension T2 of the mortar ₇ is relatively large. Since the second bent portion 31b cannot be formed, the low-rigidity member 31 has a substantially L-shaped cross-sectional shape in which only the first bent portion 31a is formed. The other end of the low-rigidity member 31 overlaps the bent portion 32b of the high-rigidity member 32 to close the gap between the landing threshold 1 and the hoistway wall 5 . After installing the partition plate 3 in this way, by pouring an appropriate amount of mortar 7, an appropriate landing threshold device A can be completed even when the thickness dimension of the floor finish is large.

As described above, the landing sill device of this embodiment includes the landing sill 1 arranged along the lower edge of the landing opening and guiding the opening and closing operation of the landing door 4, the fixture 2 to which the landing sill 1 is attached, and the landing. A partition plate 3 for closing the gap between the threshold 1 and the hoistway wall 5 to prevent mortar used for finishing the landing floor from flowing into the hoistway 21 through the gap, the partition plate 3 A low-rigidity member 31 having a bending strength capable of being bent on site, one end of which is sandwiched between the landing threshold 1 and the fixture 2 and the other end of which extends toward the hoistway wall 5 , and a predetermined height higher than the low-rigidity member 31 . and a high-rigidity member 32 whose one end overlaps the other end of the low-rigidity member 31 and whose other end is fixed to the upper surface of the hoistway wall 5 .

According to such a configuration, the partition plate 3 has a divided structure of the low-rigidity member 31 and the high-rigidity member 32, and the overlapping margin of the low-rigidity member 31 and the high-rigidity member 32 allows the height direction and the depth direction of the hoistway 21 to move. By enabling adjustment, it is possible to easily deal with relatively large dimensional errors of the building in the height direction and the depth direction of the hoistway 21, and the partition plate 3 can be lifted up and down from the side of the landing threshold 1. Projection to the road 21 side can be prevented. In addition, since the low-rigidity member 31 has a bending strength capable of being bent on site, the partition plate 3 can be installed by bending it into a predetermined shape without requiring special equipment.

In addition to the configuration described above, the landing sill device of the present embodiment has the high-rigidity member 32 fixed to the upper surface of the hoistway wall 5 by fasteners 33, and the fasteners 33 are attached to the high-rigidity member 32. A long hole 32 a is formed to allow the position of the hoistway 21 to be changed in the depth direction with respect to the high-rigidity member 32 .

According to such a configuration, it is possible to easily cope with a large dimensional error in the depth direction of the hoistway 21 .

Next, an elevator hall threshold device A according to a second embodiment of the present invention will be described with reference to FIG. Duplicate descriptions of common points with the first embodiment will be omitted.

In Example 1, the thickness dimensions of the floor finish (thickness dimensions T ₁ and T ₂ of the mortar 7) were relatively thick. The partition plate 3 was able to be configured in this state. However, when the thickness of the floor finish (thickness of the mortar 7) is reduced, the upper end of the bent portion 32b becomes higher than the upper surface of the fixture 2, and there is a possibility that the low-rigidity member 31 cannot be installed.

Therefore _, in the elevator landing threshold device A of this embodiment shown in FIG. placed downwards. Thereby, even when the thickness dimension T3 of the mortar 7 is small, the partition plate ₃ closing the gap between the landing threshold 1 and the hoistway wall 5 can be formed.

It should be noted that the present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the described configurations. It is also possible to replace part of the configuration of one embodiment with the configuration of another embodiment, or to add the configuration of another embodiment to the configuration of one embodiment. Moreover, it is possible to add, delete, or replace a part of the configuration of each embodiment with another configuration.
