Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a lighting instrument device.

[Conventional technology]

Conventionally, this type of lighting instrument device was developed in the 1980s.
Publication No. 92120, Publication No. 13168 of 1983, etc. are known.

6 and 7 show conventional structures, and the first conventional structure shown in FIG. 6 has an instrument body 53 having a pointer 52 inside a rear case 51, and a scale and a scale on the instrument body 53.
A display plate 54 on which numbers and the like are formed is attached, a front case 57 consisting of a facing plate 55 and a front transparent plate 56 is attached to the rear case 51 with a screw or hook engagement structure, and an illumination light 58 is attached to the upper part of the front case 57. A lighting case 59 is attached thereto, and the front surface of the display board 54 is illuminated from the front by the lighting lamps 58.

In addition, in the second conventional structure shown in FIG. 7, an illumination light 58 is installed inside the rear case 51 to illuminate the back side of the display board 54 and reflect the light from a facing plate 55 serving as the front case 57, so that the front surface of the display board 54 is directed forward. It is designed so that it can be illuminated from both sides.

[Problem that the invention attempts to solve]

However, in the case of these conventional structures, the first conventional structure requires a lighting case 59, etc., which increases the number of parts and the effort of assembling.
In addition, in the case of the second conventional structure, since the front side of the display board 54 is illuminated by the illumination light that is passed from the rear to the front, the illumination of the front side of the display board 54 and the pointer 52 tends to be incomplete in terms of uniformity, brightness, etc. have.

[Means for solving problems]

The purpose of the present invention is to eliminate these inconveniences, and its gist is that the instrument body and display board are housed inside an instrument case made by assembling a rear case and a front case, and that the display board is In a device in which the front surface is illuminated from the front with a lighting lamp, the rear case is formed to extend toward the front case, a mounting portion is formed in the front case, and between the mounting portion and the extension portion of the rear case. A lighting instrument device is characterized in that it includes a holding member that holds the illumination lamp.

[Effect]

A holding member for holding the illumination light is provided between the mounting portion of the front case and the forward extension of the rear case.

〔Example〕

1 to 5 show preferred embodiments of the present invention, FIGS. 1 to 4 are the first embodiment, and FIG. 5 is the second embodiment.

In the first embodiment shown in FIGS. 1 to 4, 1 is an instrument case, and the instrument case 1 is composed of a rear case 2 and a front case 3, and furthermore, in this case, the front case 3 has a facing plate 3a. Inside the instrument case 1, there is provided an instrument body 5 having a pointer 4 and a display board 6 on which scales, numbers, etc. are formed, and the rear case 2 and the front case 3 are connected to a hook part 7.
It is designed to be assembled by the engaging action of the hook portion 8.

9 is a mounting part, and the mounting part 9 is attached to the front case 3.
The upper wall of the facing plate 3a, which is a part of the front panel, is formed in a groove shape and has screw holes 10 formed therein.

11 is an extension part, and the extension part 11 is formed by extending the rear case 2 toward the front case 3 side.

Reference numeral 12 denotes a holding member, in this case, the holding member 12 is formed of a printed wiring board, an illumination light 13 is provided on the holding member 12, and the holding member 12 is attached to the mounting portion 9.
The screw 14 is inserted into the groove of the screw hole 10, and the screw 14 is screwed into the screw hole 10.

15 is a colored lens.

Since this first embodiment has the above configuration, the holding member 12 for holding the illumination lamp 13 can be provided between the extension part 11 of the rear case 2 and the mounting part 9 of the front case 3, and the display plate 6 The front surface of the device can be illuminated from the front, the number of parts can be reduced without deteriorating the illumination effect, assembly costs can be reduced, and good illumination can be obtained.

The second embodiment shown in FIG. 5 shows another example of the mounting structure of the holding member 12. In the first embodiment, the upper end surface of the holding member 12 only comes into contact with the inner surface of the extension part 11, but this second embodiment shows another example of the mounting structure of the holding member 12. In the embodiment, a raised portion 16 is formed on the facing plate 3a which is a part of the front case 3,
The extension part 11 is assembled to the rising part 16 by screwing the screw hole 18 into the screw hole 17 of the rising part 16.

Even in this second embodiment, the same effects as in the first embodiment can be obtained.

As another embodiment, the holding member 12 may be a simple mounting plate other than a printed wiring board, and the shape of the mounting portion 9 is not limited to a groove, but may be a simple raised portion.

Further, although the shape of the extension part 11 is such that the entire upper part of the instrument case 1 is extended forward in the above embodiment, it can also be applied to a shape in which only a portion, for example, only the central part is extended.

[Effect of idea]

As described above, the present invention allows the holding member that holds the illumination light to be provided between the extension part of the rear case and the mounting part of the front case, and the front surface of the display board can be illuminated from the front, reducing the illumination effect. It is possible to reduce the number of parts, reduce assembly costs, and obtain good illumination without having to do anything.

As described above, the intended purpose can be fully achieved.
