Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a car position display device provided at each floor landing in an elevator, for example.

Conventionally, this type of display device, as shown in FIGS. 1 to 3, has a machine frame embedded in a building wall a, an illumination light C provided in the machine frame, and A decorative board e having a through hole d is attached to the front opening of the machine frame located at , and a rectangular cylinder f that also serves as a guide is attached to the inside of this decorative board e at each claw part g1 of each holding member g. A display dial plate and a colored transparent plate i are successively inserted into the through hole d of the decorative plate e, and these are elastically pressed together by a pair of leaf springs k.

On the other hand, the conventional display device shown in FIG.
A counterbore e1 is provided on the inner surface of the cylindrical member, and a rectangular cylinder f is dropped into the counterbore e1 to prevent leakage of the luminous flux, and the rectangular cylinder f is fixed with the claw g1 of each holding member g. However, this prevents the light from the illumination light C from leaking from the joint.

However, in each of the display devices described above, since the rectangular cylinder body f is fixed by the claws g1 of each holding member g, the insertion of the display dial plate and the colored transparent plate i is hindered by the claws g1. In addition, in each display device using a decorative board with a counterbore portion e1 and a decorative board without a counterbore portion,
Since the lengths of the rectangular cylinders f are slightly different and the rectangular cylinders f cannot be used as common parts for each display device, each rectangular cylinder f and each holding member g are made of different parts. , which must be processed and prepared in advance, which not only increases costs but also makes it difficult to achieve labor savings through mass production.

In view of the above-mentioned points, the present invention provides a rectangular cylinder and a holding member that can be used in common with both decorative boards with and without counterbores, thereby reducing the number of parts. To provide a display device that allows two types of display devices to be easily and selectively assembled, saves labor through mass production, and can be provided at low cost.

Hereinafter, the present invention will be described with reference to an illustrated embodiment.

In FIGS. 5 to 8, reference numeral 1 denotes a machine frame with a U-shaped cross section that is embedded in the building wall 2. On the inner wall of the machine frame 1, illumination lights 3 are installed at the openings of the machine frame 1. It is provided to illuminate 1a.

In addition, a through hole 4 is provided in the building wall 2 where this opening 1a is located.
A decorative board 4 having a shape is attached, and this decorative board 4
A rectangular tube body 5 that also serves as a guide is provided on the back side of the tube, as shown in FIG.

That is, each retaining portion 5a is provided on the upper and lower outer wall surfaces of this rectangular cylinder 5.
, a mounting hole 5b and a spring locking hole 5C are provided, respectively, and in particular, the position of each retaining part 5a is located at a distance greater than the distances A and B from each end, as shown in FIG. A is a shorter distance than B.

Therefore, when using the decorative board 4 without dust holes (see FIG. 5), the edge of the square tube 5 on the A side is brought into contact with the back side of the decorative board 4, and on the other hand, as shown in FIG. When used in a decorative board 4 with a counterbore as shown in FIG.

On the other hand, on the inside of the decorative board 4 is a base 6 of each holding member 6.
a is fixed by each mounting member 7, and each retaining groove 6b of each holding member 6 engages with each of the above-mentioned retaining portions 5a, and the square tube body 5 is fixed so as not to move inadvertently. There is.

On the other hand, a display dial plate 8 and a colored transparent plate 9 are provided in the through hole 4a of the decorative plate 4, guided in order by the square tube body 5, and the colored transparent plate 9 is shown in FIG. like,
It is fixed by an end 10b of a caul plate 10 having a long hole 10a.

Furthermore, this patch plate 10 is firmly attached to the attachment hole 5b of the rectangular tube body 5 with an attachment member 11.

Therefore, the display dial plate 8 and the colored transparent plate 9 are conventionally
Not only can this type of holding member g be smoothly inserted without being hindered by the claw g1, but also the decorative board 4 can be inserted by inverting the rectangular cylinder body 5.
Even if there is a zero counterbore portion 4b, the same rectangular cylinder 5 can be used by inverting it.

Next, the embodiment shown in FIG. 6 is another embodiment of the present invention, in which the display dial plate 8 is moved by the elasticity of each pair of springs 12 instead of the respective backing plates 10. and a colored transparent plate 9 are fixed, and is substantially the same as the specific example described above.

As described above, according to the present invention, the opening 1a of the machine frame 1
A display dial plate 8 and a colored transparent plate 9 are inserted into the through holes 4a of the decorative plate 4, and a lighting lamp is installed in the machine frame 1 located behind the colored transparent plate 9. A rectangular tube body 5 is provided on the inner side of the decorative board 4, and retaining portions 5a are provided protrudingly on the outer side wall of the rectangular tube body 5 so as to engage with each of the retaining portions 5a. Each holding member 6 is attached to the decorative plate 4, and the colored transparent plate 9 is fixed with each backing plate 10 or each spring 12 provided on the inside of the rectangular cylinder 5, so there are no common parts. Not only can it be used for two types of display devices, but it is also easy to assemble, so it has practical effects such as saving labor through mass production and being able to provide it at low cost.
