Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator display device installed near a passenger car or a landing entrance, and particularly relates to an elevator display device whose cover is made of enamel.

[Conventional technology]

Generally, an elevator display device is provided inside the car or near the entrance/exit of the hall. Since this elevator display device is installed in a position where users can easily see it, it is desired that it is free from dirt and scratches and has a certain degree of aesthetic appearance in terms of color and other aspects. Therefore, in conventional elevator display devices,
For example, the cover is made of stainless steel material to prevent graffiti and scratches.

On the other hand, enamel wood has recently been attracting attention as a construction material for housing equipment such as buildings, and this enamel material has the advantages of being highly fire resistant, hardly causing any external damage, and being rich in color and with little deterioration of color. have. For this reason, enamel material is increasingly being used for the above-mentioned covers.

FIG. 2 shows a sectional view of a display device including a cover 1 made of enamel, a button 2 having a flange 2a, a case 3, and the like. Cover 1 is made by applying glaze 1b on base metal 1a and drying it at 800°C to 850°C.
It is made of enamel that is fired. Behind this cover 1 is a case 3 that stores lamps, etc.
is fixed with screws (not shown), and a button 2 is assembled into a button hole notch 1e of the cover 1 as shown. By the way, when manufacturing the cover 1, the base metal 1a
Due to the difference in the coefficient of thermal expansion of the powder powder 1b, firing distortion generating parts 1c and 1d are formed at the cover end and the button hole notch, and these firing distortion generating parts 1c and 1d
As a result, a gap G was created between the cover 1 and the button 2 as shown in the figure.

Incidentally, as a technique related to an elevator display device, Japanese Utility Model Application Publication No. 58-20262 and the like can be cited.

[The problem that the idea attempts to solve]

As mentioned above, in an elevator display device using a conventional enamel cover, firing distortion occurs at the end of the base metal 1a and the button hole notch 1e during firing.
As a result of a gap G being formed between the cover 1 and the button 2 due to the firing distortion generating portions 1c and 1d, the fixation of the button 2 was poor and the aesthetic appearance was also impaired.

An object of the present invention is to provide an elevator display device that prevents a gap from being formed between a cover and a button due to firing distortion.

[Means to solve the problem]

In order to achieve the above object, the present invention is located on the outer periphery of the firing distortion generation part that occurs in the button hole notch of the enamel cover, and protrudes toward the cover side with respect to the protrusion dimension of the firing distortion generation part. The button is characterized by a protrusion formed on the flange of the button.

[Effect]

Since the elevator display device according to the present invention has the above-described configuration, even if firing distortion occurs in the button hole notch of the cover, the firing distortion can be prevented by the protruding part of the collar formed so as to wrap it inside. Since the generating part is located inside the protruding part, and the protruding part is in contact with the cover where there is no firing distortion, the fixation of the button is improved without forming a gap between the two, and the aesthetic appearance is improved. can be improved.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 is a front view of the vicinity of the elevator landing entrance, in which a door 4 that can be opened and closed is constructed within a three-sided frame 5, and an elevator display device, that is, a hall display device 7 is constructed on a building wall 6 in the vicinity. ing.

FIG. 1 is a sectional view of the hall display device 7 taken along line A-A in FIG. 3. FIG.

This landing display device 7 has a case 3 and a cover 1.
is attached by screws (not shown), and in this respect it is the same as the conventional structure shown in FIG.
Cover 1 is made of enamel glaze 1 on base metal 1a.
b is applied, dried, and fired at 800 to 850°C to form an enamel plate. In the button hole notch 1e formed in the center of the cover 1, a firing strain generation part 1d is generated during enamel firing. In order to prevent the gap that conventionally occurs due to this firing strain generating portion 1d, the collar 2a of the button 2 is located on the outer periphery of the firing strain generating portion 1d and has a cover larger than the protruding dimension due to the firing strain generating portion 1d. A protruding portion 2b protruding toward the first side is formed.

Therefore, as shown in FIG.
When the button 2 is placed at point e, the protruding portion 2b formed on the collar 2a wraps inside the firing strain generating portion 1d formed in the button hole cutout portion 1e and comes into contact with the surface of the cover 1 where firing strain does not occur. do. Due to such contact between the two, there is almost no gap between the button 2 and the cover 1, which improves the fixity of the button 2 and improves the aesthetic appearance, thereby providing a hall display device 7 with excellent design.

In this embodiment, the structure of the hall display device 7 has been described, but the present invention can be similarly applied to a display device inside a car. Furthermore, in this embodiment, although the protrusion 2b that protrudes toward the cover 1 side is actively formed on the flange 2a, the thickness of the flange 2a is larger than the firing strain generation portion 1d.
If the thickness is sufficiently thick relative to the protrusion dimension, a concave portion may be formed in the collar 2a at a position facing the firing strain generating portion 1d, and a protrusion portion 2b protruding toward the cover 1 side may be formed on the outside of the concave portion. good.

[Effect of idea]

As explained above, the present invention wraps around the firing strain generation area generated by the buttonhole notch, is located outside of the firing strain generation area, and is located closer to the cover than the protruding dimension of the firing strain generation area. Since the protruding portion is formed, the protruding portion can be brought into contact with the surface of the cover avoiding the firing strain generating portion, and furthermore, this protruding portion can be brought into contact with the cover regardless of the presence of the firing strain generating portion. Thus, an elevator display device with improved button fixation and aesthetic appearance and excellent design can be obtained.
