Abstract

PROBLEM TO BE SOLVED: To provide the door sill of an elevator capable of being easily fitted without floating the extreme end of the sill even if force is applied to the extreme end of the sill. SOLUTION: This door sill of an elevator is constituted so that it is fixed by screws 14 through a plurality of fitting holes 13b provided on a sill groove 13a, and by a fixture 15 formed into L-section and having a thread part 15a, at least the one position is fixed. Hereby, because a plurality of positions are fixed with the screws 14 and at least one position is fixed by the fixture 15, the extreme end of the sill 13 can be prevented from floating up, and because a plurality of the positions are fixed by the screws 14, the fixed positions by the fixture 15 can be reduced, hence the fastening work by creeping in underfloor is reduced, and because the fixture 15 has the L-shaped section, the fixture 15 is prevented from unnecessarily rotating at the fastening work, hence the fastening work can be easily executed, consequently the fitting work can be easily executed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator sill, and more particularly to an elevator sill suitable for replacing an existing elevator with a sill.

[0002]

2. Description of the Related Art FIG. 3 is a top view showing a conventional elevator sill, and FIG. 4 is a cross-sectional view taken along the line AA of FIG.

As shown in FIGS. 3 and 4, an elevator car 1 has a side plate 2 forming a side surface, a floor frame 3 forming a bottom lattice, a floor plate 4 fixed to the floor frame 3, and an entrance / exit. It has a door 5 movably arranged in the section and a threshold 6 for guiding the opening and closing of the door 5.

[0004] Further, as shown in FIG.
A plurality of mounting holes 6b are provided in the sill groove 6a.
It was fixed to the floor plate 4 with screws 8 via b.

In the conventional sill configured as described above, since the sill groove 6a and the floor plate 4 are fixed by screws 8, a force is applied to the tip of the sill 6 in a direction in which the sill 6 is lifted. , The tip of the threshold 6 may rise.

As an elevator threshold for solving this problem, for example, one described in Japanese Utility Model Laid-Open Publication No. 63-130480 has been proposed.

FIG. 5 is a top view showing a conventional elevator threshold described in Japanese Utility Model Laid-Open No. 63-130480, and FIG.
FIG. 6 is a cross-sectional view taken along the line AA showing a method of attaching the sill of FIG. 5. The same components as those shown in FIGS. 3 and 4 are denoted by the same reference numerals.

A conventional elevator sill 12 described in Japanese Utility Model Laid-Open Publication No. 63-130480, as shown in FIG.
A flat plate 11 having a sill groove 12a and a screw portion 10 in a lower metal part 12b is provided, and the screw portion 10 of the flat plate 11 and the floor frame 3 are fixed.

[0009]

By the way, in the conventional elevator sill described above, in order to maintain the strength of fixing the sill, it was necessary to fix the sill by using the flat plate 11 at a plurality of locations at equal intervals. . In particular, when replacing the threshold of the existing elevator, the fastening of the screw portion 10 is a work under the floor, and it is necessary to perform a cramped work such as putting a hand in the floor frame 3 at a plurality of places.

Further, the flat plate 11 is provided with
Since it moves freely on b, it is difficult and complicated to insert the threaded portion 10 of the flat plate 11 when fixing at a plurality of places.

The present invention has been made in view of such a situation in the prior art, and an object of the present invention is to make it possible to easily perform an attaching operation without lifting the sill tip even if a force is applied to the sill tip. It is to provide an elevator threshold that can be used.

[0012]

SUMMARY OF THE INVENTION In order to achieve this object, the present invention relates to an elevator sill for guiding the opening and closing of a door provided at an entrance / exit portion of a car. And fixed with screws through
An L-shaped cross section is formed, and at least one portion is fixed by a fixing bracket having a screw portion.

According to the present invention constructed as described above, since a plurality of locations are fixed by the screws and at least one location is fixed by the fixing bracket, the tip of the threshold rises even when a force is applied to the tip of the threshold. Can be prevented. In addition, since a plurality of locations are fixed with the screws, the number of locations to be fixed by the fixing bracket can be reduced, thereby reducing fastening work under the floor, and the fixing bracket has an L-shaped cross section. This prevents the fixing bracket from rotating unnecessarily during the fastening operation, whereby the fastening operation can be performed more easily, and therefore, the mounting operation can be easily performed.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an elevator sill according to the present invention will be described below with reference to the drawings.

FIG. 1 is a top view showing an embodiment of an elevator sill according to the present invention, and FIG. 2 is a cross-sectional view taken along the line AA showing a method of mounting the sill of FIG. In addition, FIG.
The same components as those shown in FIG. 6 are denoted by the same reference numerals. That is, 1 is a car, 2 is a side plate, 3 is a floor frame, 4 is a floor plate, and 5 is a door.

The elevator threshold 13 of this embodiment is shown in FIG.
As shown in FIG. 5, a plurality of mounting holes 13b are provided in the sill groove 13a, and a hole is formed in the floor plate 4 so as to face the mounting holes 13b.
b, it is fixed to the floor plate 4.

A fixing member 15 having an L-shaped cross section and having a screw portion 15a is provided with
c, and a hole for screwing the screw portion 15a is formed in the floor frame 3 at one location in the center of the entrance / exit portion.
The sill 13 is fixed to the floor frame 3 by the fixing bracket 15.

In the embodiment constructed as described above, a plurality of locations are fixed with screws 14 and a central portion is fixed at one location with fixing brackets 15 which hold down the lower abutment portion 13c of the threshold 13, so that the tip of the threshold 13 is fixed. This threshold 1
3 It is possible to prevent the tip from rising.

Further, since a plurality of locations are fixed with screws 14, the number of locations to be fixed by the fixing bracket 15 can be reduced, thereby reducing the work of fastening under the floor, and the fixing bracket 15 has an L-shaped cross section. Therefore, the fixing metal 15 is prevented from rotating unnecessarily during the fastening operation, whereby the fastening operation can be performed more easily, and therefore, the mounting operation can be easily performed.

Further, since it is fixed to the floor plate 4 through the mounting hole 13b by the screw 14, the work of drilling a hole in the floor plate 4 is performed particularly when replacing with the threshold of the existing elevator.
b, thereby eliminating the need for marking work for drilling holes.

In consideration of the on-site installation work, a punch hole (not shown) is punched in advance at the center of the entrance and exit of the sill 13, so that the fixing bracket 15 is arranged in accordance with the punch hole, and the floor frame is formed. The work of aligning with the third mounting hole can be facilitated. In addition, the present embodiment shows a case where the entrance width is relatively small, and the fixing part by the fixing bracket 15 is one, but the present invention is not limited to this, and when the entrance width is relatively large, for example, 1000 mm
In the above case, a plurality of fixing fittings can be provided according to the width of the entrance.

[0022]

Since the present invention is constructed as described above, even if a force is applied to the tip of the sill, the sill can be easily mounted without the tip of the sill being lifted. Efficiency can be balanced.
