Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator door panel, and more particularly to a hold door panel structure.

[0002]

2. Description of the Related Art As is well known, an elevator hold door panel always closes the opening of the entrance and exit to prevent people and objects from falling into the hoistway, and when smoke occurs, smoke is emitted via the hoistway. It has the function of preventing it from flowing in and flame spread. For this reason, the Hold A panel is 1.5
Manufactured from steel plates with a thickness of at least mm, it is legally stipulated that the gap with the three-sided frame installed on the wall of the building around the entrance should be within a prescribed size.

Next, a general structure of the door panel will be described with reference to FIGS. 6 and 7. In FIG. 6 and FIG. 7, reference numeral 1 denotes a door panel, which includes a door panel surface plate 2 having a substantially U-shaped cross section, a reinforcement 3 lining in the longitudinal direction, and reinforcements 4 and 4 at both ends. It is configured as one. The size of the hold-up panel is about 2 m in length and 0.5 m in width for a passenger elevator installed in a general office building or the like. However,
Since a large-sized entrance / exit is adopted in an elevator for luggage, many elevators having a length of 4 to 5 m and a width of about 2 m are adopted.

FIGS. 8 and 9 show the structure of a two-door door-opening door used in an elevator for large-sized luggage, in which two hold door panels, a lower panel 5 and an upper panel 6, are connected by chains 7 and 8. A drive device 12 provided on an upper frame 11 of a frame body 10 suspended and installed in the hoistway 9.
Is driven to open and close. Guide shoes 13 are attached to the left and right end surfaces of the lower panel 5 and the upper panel 6, respectively.
The guide rail 14 of the frame body 10 is opposed to the guide shoe 13.
It is guided along and goes up and down. On the other hand, a three-sided frame 15 is installed on the building wall around the doorway, and the position of the guide shoe 13 is adjusted back and forth so that the clearance A with the hold door panel is 9 mm or less as stipulated by law. .
Reference numeral 16 indicates a counterweight, and B indicates the width of the entrance / exit.

[0005]

However, if the lower panel 5, the upper panel 6 or the like has a distortion such as a twist, the guide shoe 13 is pressed against the guide rail 14 and the guide shoe 13 is pressed.
Due to the frictional force generated between the guide rail 13 and the guide rail 14, the door panel cannot be opened and closed smoothly. That is, it is possible that the opening / closing speed becomes slower or the opening / closing becomes impossible in some cases. Also, guide shoe 13 and guide rail 14
There is a possibility that the friction A will gradually wear away and the gap A with the three-way frame 15 that was secured at the beginning of installation will become large.

Therefore, if the door panel is distorted before installation, it may be corrected before installation, but in the case of a large door panel used for an elevator for large luggage, correction by human power is impossible. Therefore, it is required to increase the plane accuracy during manufacturing in the factory. Considering the required clearance between the three-sided frame 15 and the three-sided frame 15 is about 5 mm (the legally prescribed size is 9 mm or less, but there is a margin), the plane accuracy required for the hold-a panel is 3 to 4 at maximum.
It will be about mm.

However, in order to manufacture a large hold door panel while maintaining such a high level of precision, much labor and time are required, resulting in an increase in cost. That is, it is necessary to correct the distortion by using a steel plate having high plane accuracy, attaching a reinforcing plate or the like with welding or an adhesive, and then applying pressure or locally heating. In addition, a large surface plate and measurement jig are required to determine whether the manufactured hold-back panel is kept within the specified accuracy range, and many inspection tasks are performed using these. Labor is required. Further, even in the installation work, much labor is required to adjust the clearance between the three-way frame and the specified size.

Therefore, an object of the present invention is that, even if it is a large door panel, it does not require a lot of man-hours for manufacturing, it does not require a lot of labor for installation work, and it has a predetermined clearance with the three-way frame. It is to provide an elevator door panel that can secure the.

[0009]

In order to achieve the above-mentioned object, the present invention provides a door panel main body for closing an entrance / exit opening in which a three-way frame is installed, a door panel body facing the three-way frame, and a thickness outside the door panel body. The frame member is attached so that the position in the direction can be adjusted.

[0010]

The door panel main body for closing the door opening and the frame member facing the three-way frame are separated, and the frame member can be attached to the door panel main body so that the position in the thickness direction can be adjusted. Even if the main body is distorted when it is manufactured or installed, there is no need to correct it, and a specified gap can be secured with the three-way frame.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a rear view showing an embodiment of the present invention, FIG.
3 is a FF sectional view of FIG. 1, and FIG. 3 is a GG sectional view of FIG.

In FIGS. 1, 2 and 3, reference numeral 20 denotes a hold door panel. The hold door panel 20 includes a main part 21 of a main body of a door panel and a plurality of fixing bolts 22 on the main part 21 of the main body of the door panel. The gap adjusting frame portion 23 is fixed via the gap adjusting frame portion 23, and the gap adjusting frame portion 23 faces a three-way frame (not shown). Hereinafter, the configuration of each unit will be described in detail.

The main portion 21 of the main body of the door panel has a length C slightly smaller than the width B of the doorway (about 20 to 30 mm), and the width is about 1/2 of the height of the doorway (in the case of two doors), A door panel body 24 having a substantially U-shaped cross section, a reinforcement 25 lining in the longitudinal direction, and reinforcements 26 at both ends in the longitudinal direction,
The reinforcing bolt 24 and the door panel main body 24 are provided with through holes for the fixing bolts 22 at the upper side and the lower side of the door panel body 24.

Further, the gap adjusting frame portion 23 has a size such that the main portion 21 of the door panel main body can be inserted inside, and an upper frame 27 and a lower frame 28 whose cross sections are bent in a U shape, and a cross section The vertical frames 29, 29, which are bent in a letter shape, at both ends in the longitudinal direction are integrally configured. Then, in the gap adjusting frame portion 23, as shown in FIG. 4, the door panel main body main portion 21 can move in the thickness direction on each side that is inside the upper frame 27, the lower frame 28, and the vertical frame 29. Through hole of the fixing bolt 22 as a long hole 30
A mounting hole (not shown) for the guide shoe 13 is provided on the outer side of 29.

The gap adjusting frame portion 23 configured as described above
Install the guide shoe 13 on the vertical frame 29 of the
The vertical frame 29 is fixed at a fixed position so that the dimension from the surface thereof is 9 mm or less. Further, the gap adjusting frame portion 23 is designed to travel a little to the surface side from the surface of the main portion 21 of the door panel main body, and the dimension D thereof is set to a dimension capable of absorbing the manufacturing accuracy of the main body.

Next, the operation of the embodiment configured as described above will be described. The main part 21 of the main body of the door panel has almost the same structure as a conventional hold door panel and has a structure capable of withstanding an external collision or a load. Therefore, the plane accuracy at the time of manufacture becomes almost the same as the conventional one. On the other hand, the gap adjusting frame portion 23 has a small width for all of the upper frame 27, the lower frame 28, and the vertical frame 30, so that there is no possibility of planar twist, and the plane accuracy can be kept high. The gap adjusting frame portion (23) is assembled on a plane, the door panel main body portion (21) is incorporated inside thereof, and the fixing bolts (22) fix each other.

In the case of this assembling, it corresponds to the plane strain E of the main part of the main body 21 of the door panel shown in FIG. 4, and the other side of the frame 23 for adjusting the gap by the dimension D as shown in FIG. Retract from the surface. That is, the dimension D is a dimension capable of absorbing the plane strain E of the main part of the main part 21 of the door panel body. The guide shoe 13 is attached to the vertical frame 29 of the gap adjusting frame 23 after or before the assembling with bolts so that the gap between the hold door panel 20 and the three-way frame 15 is equal to or less than the specified dimension.

Therefore, in the embodiment constructed as described above, even if the main portion 21 of the door panel main body has a plane distortion at the time of manufacture, it can be attached to the gap adjusting frame portion 23 without special correction work. Therefore, it is possible to shorten the production time because the skill and the strain-removing work which takes a long time, which are conventionally required, are unnecessary. As a result, the plane formed by the gap adjusting frame portion 23 around the hold door panel 20 produced as a result is produced with a certain accuracy. Since the main part 21 of the door panel main body is incorporated inside the peripheral clearance adjusting frame 23 and is retracted by the dimension D from the surface thereof, even if there is a plane strain E, the main part 21 is provided in the clearance with the three-way frame 15. It does not affect. Further, since the guide shoe 13 is at a fixed position from the gap adjusting frame portion 23, the hold shoe panel 20
It is not necessary to readjust the clearance between the three-way frame 15 and the guide shoe 14 when the vehicle is brought into the field and installed. further,
Since the twist of the hold-back panel 20 does not affect the surface pressure of the guide shoe 13, it does not affect the fluctuation of the clearance due to the wear of the guide shoe 13.

[0019]

As described above, according to the present invention, the door panel main body having mechanical strength and the frame member for maintaining the clearance accuracy between the three-way frame and the door frame body are separated from each other. Elevator door panel that keeps the gap with the three-sided frame below a specified dimension without effectively removing strain even if plane distortion such as twisting occurs during installation work, and effectively shuts off the entrance / exit opening and hoistway Can be provided.
