Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an elevator door having a cushioning material on the door stop side end face of the opening/closing door to reduce impact and noise when the door is closed. This invention relates to an improved structure of the constituent side plates.

[Prior art]

This type of elevator door will be explained using FIGS. 1 to 3. 1 is a gate-shaped three-sided frame of the elevator landing, 2 is the entrance door of this landing, and 3 is the main body of the entrance door 2. This is the inside board. As is clear from the cross-sectional view shown in FIG. 2, this inner plate 3 is bent into a short bent part 3' on the left door stop side, and the right door pocket side is bent over the width of the door thickness. It is formed into a U-shaped cross section. 4 is an outer plate formed from a stainless steel plate and covers the inner plate 3;
This outer plate 4 has a short bent part 4' that overlaps the bent part 3' and a bent part 4'' on the door bag side, and is attached to the inner plate 3 via a screw 5 screwed from the door stop side and an adhesive. That is, the outer plate 4 is made of a stainless steel plate with excellent design, and since it is generally more expensive than a steel plate, it is polymerized as a thin stainless steel surface material on the inner plate 3 made of iron plate to ensure strength. It is fastened from the door stop side with the screws 5 and is firmly joined and fixed as a whole through adhesive. 6 is a pair of scissors that connect the outer plate 4 and the inner plate 3 to the door stop with screws 5. It is inserted so as to compensate for the gap between the door pocket side end surface of the inner plate 3 and the outer plate bent portion 4'' which is caused by the fastening at the sides.
Reference numeral 7 denotes a vertical reinforcing plate formed in a U-shape in cross section, which is fixed vertically along the inner plate 3 with a gap provided between it and the inner plate 3 on the door stop side. 8
An upper reinforcing member is arranged and fixed in the horizontal direction between the inner side plate 3 and the vertical reinforcing plate 7, and a lower reinforcing member (not shown) is similarly arranged below this upper reinforcing member 8. Then, the door stop side of the inner board 3 and the vertical reinforcing board 7
A door stop rubber 9 having a substantially convex cross section is fitted into the gap formed by the door stop rubber 9 with one shoulder of its protrusion abutting the bent portions 3' and 4' of the inner and outer plates 3 and 4. ,
The bent end of a door stop rubber presser plate 10 having an L-shaped cross section is brought into contact with the other side of the protrusion, and the other end of this presser plate 10 is fixed along the vertical reinforcing plate 7. There is.

In the elevator door according to the above configuration, when fixing the outer plate 4 to the inner plate 3, the bent portion 3' of the inner plate 3 is formed on the door stop side of the door 2 that is not visible from the landing side of the door, Since the outer plate 4 was screwed into this bent part 3' with the screw 5, the side surface of the landing side protrusion where the bent parts 3' and 4' of the door stop rubber 9 come into contact with, that is, the door stop rubber having a convex cross section. On one shoulder of 9,
It is necessary to provide a step compared to the shoulder portion on the other side that comes into contact with the door stop rubber presser 10, and the symmetry of the door stop rubber 9 is lost. In addition, as mentioned above, the screws 5 screwed in from the door stop side are used to fix the outer panel 4 and the inner panel 3.
On the other hand, the inner plate 3 and the outer plate 4
This creates a gap on the door pocket side, and the extra effort of fitting scissors 6 is required to adjust the gap. Furthermore, due to the need to form the screws 5 on the door stop side and the outer plate 4 flush, a finishing process was applied to the door stop side of the door 2 to smooth that part. Even with this process, it was difficult to expect a perfect finish.

[Summary of the idea]

The present invention was made to solve the above-mentioned drawbacks, and it has good workability, does not expose the door fixing member in appearance, and has a convex cross-sectional shape of the door stop rubber, that is, the cushioning material. The aim is to obtain an elevator door that does not lose its symmetry, and its feature is that it is constructed by providing a gate-shaped three-sided frame of the elevator landing with an opening/closing door that opens and closes between the three-sided frames. In the elevator door, the opening/closing door includes an outer plate having an L-shaped cross section on the door stop side, an inner plate whose tip is overlapped with the inner surface of the bent part of the outer plate, and the outer plate. The outer plate and the inner plate are provided with a cushioning member having a substantially convex cross section with one side shoulder in contact with the bent end of the plate, and the outer plate and the inner plate are connected to each other by countersunk screws from the outside at a portion shielded by the three-sided frame. They are connected and fixed to each other by fastening members such as.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 4 and 5, but this embodiment differs from the conventional example only in the inner plate, the rubber doorstop, and the mounting position of the screws. . That is, the inner plate 11 is not provided with the bent portion 3' of the conventional one described above,
The tip thereof is the door stop side bent part 14' of the outer plate 14.
It is in contact with the inner surface. And this inner and outer plate 1
1 and 14 are fixed by screwing countersunk screws 13 together at a portion of the door 12 that is shielded by the three-sided frame 1 on the landing side (see FIG. 5). Further, the doorstop rubber 15 disposed on the doorstop side is configured as a symmetrical convex shape without a notch, and is located between the tip of the outer plate 14 on the doorstop side and the tip of the doorstop rubber pressing plate 10. is held in place.

In the elevator door according to the above configuration, the fixing part between the outer plate 14 and the inner plate 11 is not provided on the door stop side of the door, so the bent part 3' at the tip of the inner plate unlike the conventional one can be omitted. Therefore, by making the door stop rubber 15 symmetrical, it is possible to expect an even cushioning effect, and at the same time, it is possible to improve the appearance and workability of the end face of the door stop that does not require finishing. And the outer plate 14
By arranging the fixing part between the door side plate and the inner side plate 11 to be the part on the front side of the door that is shielded by the three-sided landing frame, it is possible to securely fix the door side plate without exposing the fixing part from the outside. This has the advantage of not requiring separate finishing work on the fixed part.

[Effect of idea]

As described above, according to the present invention, it is possible to improve the workability of joining and fixing the inner and outer panels constituting the door, and to achieve more reliable fixation.
In addition, the cushioning material provided in the door stop does not lose the symmetry of its convex cross-sectional shape as in the past, and can be expected to have an even cushioning effect.
Moreover, there is an effect that a visually excellent elevator door can be obtained without the fixed portion being exposed externally.
