Description

[Detailed Description of the Invention] This invention relates to an improvement of elevator doors provided in elevator halls and the like.

First, a conventional elevator hall door will be explained with reference to FIGS. 1 to 4. Figures 1 to 3
In the figures up to the figure, 1 is a door and 2 is a three-sided frame. The door 1 has a coating film 5 formed on the surface of the door body 4, which is made of a molded steel plate according to fire prevention regulations. A transparent glass plate 3 is placed in close contact with this, and the outer periphery of the glass plate 3 is clamped to the door body 4 by a metal joint member 6 fixed to the door body 4. Also,
A cushioning material 8 made of rubber or the like is clamped between the upper and lower end surfaces of the glass plate 3, the joint member 6, and the baseboard 7. Note that 9 in Figure 2 is the threshold of the landing.

In the landing door constructed as described above, by placing the transparent glass plate 3 along the painted surface of the door body 4, the depth of the color of the coating film 5 on the surface of the door body 4 is increased and the appearance is improved. ing. Such a door 1 requires a door body 4 made of steel plate according to fire prevention regulations, and is also used to ensure the rigidity of the door and to attach an engaging device for opening and closing the door 1 in conjunction with the car door. It is necessary to attach various reinforcing members, brackets, etc. Due to these reasons, the surface of the door body 4 inevitably has some waviness and local unevenness when viewed microscopically, as shown in a partially enlarged view in FIG. Therefore, in the conventional landing door described above, the unevenness of the coating film 5 of the door body 4 causes the glass plate 3 to
If these parts are brought into close contact with each other, some parts will be crimped more strongly than others, and the strongly crimped parts will look like stains and be unsightly.Also, the difference in temperature between the inside of the hoistway and the landing side will cause problems. Therefore, the moisture in the minute air layer that forms between the glass plate 3 and the coating film 5 of the door body 4 condenses, and if left as is, the condensation causes the coating film 5 to discolor and become very unsightly. There were flaws.

This idea solves the above-mentioned drawbacks of the conventional method by fixing a glass plate with a coating film on the back side placed on the front side of the door body with a sealed air space between the glass plate and the door body. To provide an elevator door which has a good appearance without visible stains, and which is less likely to cause dew condensation between the door body and a glass plate and discoloration of a coating film caused by the condensation.

An embodiment of this invention will be described below with reference to FIGS. 5 and 6.

5 and 6, the same reference numerals as in FIGS. 1 to 3 indicate the same or corresponding parts, 10 is a coating film formed on the entire back surface of the transparent glass plate 3, and 11 is the back surface of the glass plate 3. In order to form this air layer 11, a cushioning material 8 made of an elastic material such as rubber is formed into a hook-shaped cross section and the glass is sealed. The portion 8a of the cushioning material 8 that is in contact with the outer circumference of the back surface of the glass plate 3 is brought into contact with the outer circumference of the plate 3 and the outer circumference of the back surface of the plate 3. It is crimped. Further, reference numeral 12 denotes a desiccant which is disposed within the upper end of the sealed air space 11 and clamped between the glass plate 3 and the door body 4.

The elevator landing door of the embodiment configured as described above has a coating film 10 formed on the back surface of the glass plate 3, and a sealed air layer 11 provided between the coating film 10 and the door body 4, so that the coating film 10 and Since the door body 4 is spaced apart, even if there is minute distortion or unevenness on the surface of the door body 4, the glass plate 3 and the coating film 10 are evenly adhered to each other, and the coating film 1
0 is not locally crimped to the door body 4,
Therefore, there are no spots that look like stains, and the appearance is good.

In addition, in this embodiment, a part of the cushioning material 8 is clamped between the outer periphery of the back surface of the glass plate 3 and the front surface of the door body 4, and airtight air is created between the glass plate 3 and the door body 4. Since the layer 11 is provided, dew condensation does not easily form on the surface of the coating film 10, and the coating film 10 can be prevented from discoloring due to condensation, and can be used for a long period of time with good appearance. 11 and desiccant 12
This feature ensures that condensation is prevented even if the landing door is installed in a location where condensation is likely to occur.

In this embodiment, the desiccant 12 does not necessarily have to be placed in the upper end of the sealed air layer 11, but it is preferable to place it in a part that cannot be seen from the front surface of the door 1 due to the joint member 6 or the like.

Although the above-described embodiments have been described with respect to landing doors, this invention can also be applied to elevator car doors.

As explained above, the elevator door of this invention has a coating film formed on the back side of the glass plate, and a sealed air layer is formed between the back side of the glass plate and the steel plate door body. This has the effect of preventing the discoloration of the paint film caused by condensation and allowing it to be used for a long period of time with good appearance.
