Display device for elevator

Abstract

A display device of an elevator, wherein a mesh body (13) allowing a display on a display part (12) to be transmitted through a large number of distributedly disposed transmission parts (13a) is disposed on the front surface side of the display part (12) for displaying the operating state of an elevator car, and the front surface part of the net body (13) forms spaces surrounding the large number of transmission parts (13a), whereby since air in the large number of spaces is heated and inflated and discharged to the outside when the flame of a lighter is applied thereto, the flame can be prevented from directly touching the surface of the display part (12).

Description

technical field [0001] The invention relates to a display device arranged in at least one of the elevator car or the elevator hall to display the running state of the elevator. Background technique [0002] The display device of the elevator generally has a display device installed in the elevator car and a display device installed in the elevator hall. In addition, some operation panels have buttons on the display device, and some have the display device and the buttons independently. [0003] Here, use figure 1 Describes the structure and operation of the operation panel. The operating panel 8 of the elevator, when the user presses the buttons 6A and 6B of the operating panel 8, the elevator car starts to move until the user's location (floor). The display device 4 includes a position lamp 4A for displaying the position of the elevator car, and direction lamps 4B and 4C for displaying the moving direction of the elevator car. The current position of the elevator car is ...

Problems solved by technology

[0007] In the countermeasures described above, if the display of the button does not change with the method of covering it with a metal cover, it is enough to confirm the press by making the surrounding glow, but in the case of a display device whose entire display changes , when covered with a metal cover, it is inappropriate since the display of the display device cannot be seen

[0008] In addition, in the method of covering with a flame-retardant plastic plate, when the flame contacts the surface of the display device for a long time, the flame-retardant plastic will melt due to the heat generated by it, and the display of the display device behind it may not be visible.

[0009] On the other hand, glass materials are fire-resistant and light-transmitting, but in general, glass materials are weak in impact resistance, so in order to have a certain degree of rigidity, it is necessary to increase the thickness of the glass plate, which reduces the degree of freedom of design.

Furthermore, even if tempered glass is used as a glass material, when it is hit by a sharp object, cracks will occur, the durability will deteriorate, and there is a possibility that it will break from there.
