Description

Decoration panel fixing device for elevator door The present invention relates to a fixing device for a decorative panel of an elevator door, and more specifically, to a fixing device for a decorative panel of an elevator door configured to allow the decorative panel to be easily and conveniently installed and replaced on the door body without having to dismantle all the upper, lower, left, and right fixing holders individually, thereby improving the workability of installing and replacing the decorative panel and reducing the working time. In line with the trend toward luxury elevators, decorative panels are being installed on the interior and exterior surfaces. The above decorative panels are installed by attaching them to the inner and outer surfaces of the elevator and are made of materials such as glass, steel plates, and synthetic resins, and have a specific design printed or engraved on them to luxuriously decorate the inner and outer surfaces of the elevator. In addition, among the interior and exterior parts of the elevator, the exterior surfaces of both doors corresponding to the landing side are exposed to passengers, so ornate decorative panels made of glass are primarily installed. Below, a glass panel among the decorative panels will be explained as an example. Referring to FIG. 1, the glass panel (1) is fixedly installed on one side of the door body (3). And the glass panel (1) is fixedly installed on the door body (3) through separate upper, lower, left, and right fixing brackets (5, 6, 7, 8). The above fixing brackets (5, 6, 7, 8) are fixedly fastened to the upper, lower, left, and right parts of the door body (3) corresponding thereto while supporting the upper, lower, left, and right sides (1a, 1b, 1c, 1d) of the glass panel (1). Accordingly, the glass panel (1) is fixedly mounted on one side of the door body (3). However, this glass panel (1) has the disadvantage of being vulnerable to shock and vibration, and being very difficult and difficult to install due to the risk of damage caused by it. In particular, in the case of the glass panel (1), it must be assembled and installed directly at the work site after the elevator installation work is completed due to the risk of damage. However, during this assembly and installation process, the upper, lower, left, and right fixing brackets (5, 6, 7, 8) installed on the door body (3) must be disassembled one by one, the glass panel (1) must be placed, and then the glass panel (1) must be reassembled one by one to fix the glass panel (1) to the door body (3). In addition, on one side of the elevator door body (3) at the construction site, a construction panel is pre-installed in place of the glass panel (1). Accordingly, in order to separate the above construction panel from the above door body (3) and reinstall the above glass panel (1) in its place, there is the inconvenience of having to disassemble and reassemble all of the above upper, lower, left, and right fixing brackets (5, 6, 7, 8) one by one. This has the disadvantage that workability is reduced and the installation time of the glass panel (1) is delayed. Meanwhile, if the glass panel (1) installed on the elevator door is damaged or broken, the broken glass panel (1) must be replaced with a new one. However, in the process of replacing the glass panel (1), there is a problem in that in order to remove the damaged existing glass panel (1) from the door body (3) and replace it with a new glass panel (1), all of the upper, lower, left, and right fixing brackets (5, 6, 7, 8) must be disassembled and reassembled one by one.
