Description

[Detailed Description of the Invention] This invention relates to an improvement of a display used in an elevator.

Various indicators are installed on the three sides of the elevator landing. These indicators usually consist of a display body mounted on a three-sided frame and an illumination light provided behind the display body. This display body is mounted as shown in, for example, Japanese Utility Model Application Publication No. 57-151362, and equivalent display bodies are shown in FIGS. 1 to 4.

In the figure, 1 is a three-sided landing frame, 1a is a square hole provided in the three-sided frame 1, and 2 is a transparent body with an arrow displayed on its surface, and a part of it is inserted into the square hole 1a from the front of the three-sided frame 1. A display body of a direction indicator is glued to the back surface of the three-sided frame 1, a case 3 surrounds the display body 2 and is fixed to the back surface of the three-sided frame 1, and a cover 4 covers the rear surface of the case 3 and is provided with a socket 5. , 6 is socket 5
7 is the inspection port lid that opens and closes the inspection port provided on the lower surface of the three-sided frame 1 (the upper surface of the landing entrance), 8 is the landing door provided on the hoistway side of the three-sided frame 1, and 9 is the Landing door 8 located behind the three-sided frame 1
This is a hanger case that houses a member (detailed explanation is omitted) that suspends the upper end of the shaft from the hoistway wall.

That is, when replacing the illumination lamp 6, the inspection port cover 7 is opened in the direction of arrow A, the cover 4 is removed from the inspection port, and the cover 4 is taken out from the inspection port along the direction of arrow B. Then, after replacing the lighting lamp 6,
Attach the cover 4 in the reverse order as described above.

However, for this purpose, the inspection port cover 7 is required, and in particular, when the material of the three-sided frame 1 is stainless steel plate, brass plate, etc. and requires a mirror finish or corrosion finish, processing of the inspection port, and inspection port and inspection port cover are required. Matching the corrosion patterns in item 7 is done manually and requires a lot of time. In addition, since the inspection port cover 7 is located in a place where it can be seen by elevator users, the appearance is significantly impaired. Furthermore, the depth dimension of the three-sided frame 1 is at most
Since the length is only about 200 mm, there is not enough space to replace the illumination light 6, and the work efficiency for replacement is poor.

This invention improves the above-mentioned problem by providing a protrusion on one side of the inner edge of the hole in the display mounting plate and a groove on the other side of the display body, and by engaging these to attach the display body. An object of the present invention is to provide an elevator indicator in which lighting lamps can be easily replaced from the front side of a mounting plate.

An embodiment of this invention will be described below with reference to FIGS. 5 to 9.

In the figure, 1b is a protrusion protruding from the inner edge of the square hole 1a of the three-sided frame 1, and 2a is a protrusion on the outer surface of the display body 2.
The first groove 2b is provided along the insertion direction (left-right direction in FIG. 7) and engages with the protrusion 1b;
This is a second groove that is bent upward along the outer surface of the display body 2 from the terminal end of the groove 2a.

Other than the above, it is the same as in FIGS. 1 to 4. However, the cover 4 in FIG. 2 is integrated with the case 3, and the inspection port and inspection port lid 7 are not provided.

That is, when the display body 2 is attached to the three-sided frame 1, as shown in FIGS. 6 and 7, the protrusion 1b engages with the second groove 2b, preventing the display body 2 from escaping forward. is being prevented. When replacing the illumination lamp 6, once the front part of the display body 2 is moved upward as shown by the arrow C, the protrusion 1b is aligned with the second groove 2.
deviate from b. When it is then pulled forward, the projection 1b is guided by the first groove 2a and the display body 2 escapes from the square hole 1a. Now, from the front of the three-sided frame 1, the lighting light 6
can be replaced. When the replacement is completed, the display body 2 is inserted into the square hole 1a in the reverse order as described above, and the protrusion 1b is engaged with the second groove 2b, thereby completing the entire operation.

In this way, the display body 2 and the illumination light 6 can be attached and detached from the landing side, and the inspection port and the inspection port cover 7 on the lower surface of the three-sided frame 1 are unnecessary. Moreover, even if the depth dimension of the three-sided frame 1 is small, the work of replacing the illumination light 6 is easy.

10 and 11 show another embodiment of this invention, in which the display body 2 is formed in a cylindrical shape.

In this embodiment, the direction of the second groove 2b of the display body 2 is reversed left and right. That is, as shown in FIG. 10, the second groove 2b on the right side of the figure is bent downward from the end of the first groove 2a, and the second groove 2b on the left side is bent upward.

Therefore, when removing display body 2, display body 2
When the display body 2 is rotated in the direction of arrow D in FIG. 10 and pulled forward when the protrusion 1b comes out of the second groove 2b, the display body 2 escapes from the square hole 1a. When attaching the display body 2, the operation described above may be reversed.

FIGS. 12 and 13 also show other embodiments of this invention, and the protrusion 1b and groove 2a in FIGS. 8 and 9,
The position of 2b is reversed.

In this embodiment, a groove 1c is provided at the inner edge of the square hole 1a of the three-sided frame 1, and a protrusion 2c that engages with the groove 1c is formed on the outer surface of the display body 2 along the insertion direction of the display body 2. It is set up. A second groove 2b is provided at the end of the protrusion 2c, which is bent upward from the lower surface of the protrusion 2c along the outer surface of the display body 2.

The operation of this embodiment is the same as that shown in FIGS. 8 and 9, so a description thereof will be omitted.

Moreover, it is also easy to apply this to what is shown in FIGS. 10 and 11.

Although the embodiment has been described with reference to the case where the display device is installed in the three-sided frame 1, it can also be applied to a display device installed in a landing or a car.

As described above, in this invention, for each illumination light of an elevator display, a projection is provided on one of the inner edge of the hole in the display mounting plate and the outer surface of the display, and a groove that engages with the projection is provided on the other. Since these are formed of a first part that extends in the insertion direction of the display and a second part that bends, the display can be attached without using any special members, and the display can be easily attached and detached. Therefore, the lighting lamp can be easily replaced from the front of the mounting plate.
