Description

[Detailed Description of the Invention] This invention relates to a display structure for a warning light that employs a refracted light display method and a direct light display method.

The display structure of a well-known refracted light display type warning light will be explained below with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a case body, on the front of which an outer lens 2 through which a warning display can be seen is attached, and on the rear thereof a cover plate 3 is fixed with screws or the like.

4 and 5 are inner lenses made of acrylic resin plates, bent approximately at right angles, and the part facing the outer lens 2 is a display plate 4.
a, 5a, and surfaces perpendicular to these are side plates 4b, 5b.

The side plates 4b and 5b of the inner lenses 4 and 6 are inserted side by side on one side of the case body 1 to form the display plate 4a.

5a are extended in the same direction so as to cover the front surface of the case body 1, and are overlapped with each other with a slight gap 3 on the back surface of the outer lens 2.

6 and 7 are lamps, and side plates 4b of the inner lenses 4 and 5;
, 5b at the lower end portions 4c, 5c.

Both 8 and 8' are light-shielding plates, and in particular, the light-shielding plate 8 prevents the light from the lamp 7 from leaking into the inch lens 4, and prevents the pictographs on the inner lens 4 from emitting faint light.

As shown in FIG. 2, the display plate 4a of the inner lens 4 is engraved with a picture and text indicating that the oil is out, and the display plate 5a of the other inner lens 5 is also engraved as shown in FIG. 3. For example, a picture of a battery and letters indicating a lack of electricity are engraved.

Since the above-mentioned pictures and letters are engraved on the display board, the light from the lamps 6 and 7 is diffusely reflected by the engraved portions, so that defects such as scratches can be clearly and clearly displayed.

The entire surface of the outer lens 2 is colored red.

2' are display plates 4a and 5a of the inner lenses 4 and 5 of the Ura-hyaku.
The mackerel corresponding to the mackerel is used as a display window, and the mackerel γ other than the display window 7 is covered with a mask member (not shown) that does not transmit light, or is directly colored black.

Attach the warning light of the above structure to a suitable mounting panel.

The conventional refracted light display type warning light has the above-mentioned configuration, so when the oil level falls below a predetermined level, the lamp 6 lights up, and a picture and text indicating that the oil is out are displayed on the display window 2' of the outer lens 2, as shown in Fig. 2. is displayed.

Similarly, when the battery voltage falls below the set voltage, the lamp 7 lights up and a picture and text indicating the voltage drop are displayed on the display window 2' of the outer lens 2, as shown in FIG.

Also, when the lamps 6.1 are turned on at the same time at the time of start-up inspection, the pictures and letters of FIGS. 2 and 3 are displayed in an overlapping position on the outer lens 2, thereby making it possible to check for broken bulbs.

By the way, the above-mentioned refracted light display method is a display method that is rich in subtle changes, is innovative, and has high commercial value, but the drawback of this method is that it is easily affected by sunlight, and when exposed to sunlight, the display will not be visible. This is extremely difficult to see.

This invention is an improvement on the above-mentioned drawbacks of the conventional warning light.The structure of this invention will be explained below with reference to FIGS. 4 to 7.

An open side space 1a in which the side plates 4b and 5b of the inner lenses 4 and 5 are expanded outwardly on both sides of the case body 1.

1a, lower ends 4c, 5 of both side plates 4b, 5b.
c is an inlet light gap 1b with a lamp diameter of 7;

The lamp 6.7 is arranged so that the lamp light shines through 1b.

The display plates 4at53 of the inner lenses 4 and 5 extend horizontally inward to cover the front surface of the case body 1, and are overlapped with each other with a slight gap between them on the back surface of the outer lens 2.

The entire surface of the outer lens 2 is colored red, and furthermore, pilot display windows 10 and 11 are provided at the bottom facing the lamps 6 and 7 of the outer lens 2, and also facing the pictograms on the display boards 4a and 5a of the inner lenses 4 and 5. Display window 2'
It is formed.

The display window 2' and the pilot display windows 10 and 1
Part 2 other than 1 is covered with a suitable mask member (not shown) to prevent light from passing through.

In addition, the back surfaces of the pilot display windows 10 and 11 are made thin with longitudinal grooves etc. cut in order to allow as much light to pass through.

Note that 9 is a mounting panel for a warning light.

With such a warning light display structure, when the battery voltage drops below the set voltage, the lamp 7 lights up and displays as shown in FIG. 5.

That is, a picture of a battery and the letters CHG are displayed using refracted light, and since the light from the lamp 7 directly hits the pilot display window 11, a direct light display is also performed.

Therefore, even if the refracted light display section is exposed to sunlight, visibility will not deteriorate because the display is also performed using direct light.

Furthermore, when the oil level falls below a predetermined level, the lamp 6 lights up and not only a picture and text of the oil tank as shown in FIG. 6 are displayed, but also a direct light display is performed on the pilot display window 10. .

Furthermore, when inspecting the lamp 6.7 for burnout during startup inspection, the pictures and letters of the battery and oil tank are displayed simultaneously as shown in Figure 7, and the pilot display windows 1 on both sides are displayed simultaneously.
0 and 11 are also displayed by direct light.

As mentioned above, this device has a semi-transparent flat plate whose entire surface is colored red, etc., with the central part serving as a display window area, and vertical grooves etched on both sides of the back surface to form pilot display windows. It has one outer lens, a display plate part with the same volume as the display window area of the outer lens, and a side plate part with one side of the display plate part bent into an approximate shape, and the whole has a constant thickness. Two inner lenses made of thick transparent resin plates, with pictographs etc. engraved on the display plate part, a part corresponding to the display window of the outer lens left in the window frame method, and other parts masked to be opaque;
The case body has lamps on both sides, and a case body in which an open side space that expands outward on both sides is formed with an entrance light gap having a width of 7 times the lamp diameter on the front side of the lamp, and an outer lens on the front side of the case body. The pilot display windows on both sides are mounted so that the lamps directly press the display window area, and the central display window area is shielded from light. They are superimposed in parallel with a gap between them, and are installed symmetrically within the case body so that the end faces of each side plate face the lamps in the installation space on both sides of the case body, and the inner lenses of each inner lens are Since the end face of the display board part does not reach the open side space of the opposite inner lens, lamp light can be introduced directly from the end face of the inner lens, and most of the light on the entrance side can be introduced at the abbreviated bent part. Since almost all of the light is reflected toward the display panel, the amount of lamp light incident on the display panel is large, and by masking the window of the display section, a clear refracted light display is possible. The inner lens can be constructed by simply bending a flat plate into an abbreviated shape, making it extremely easy to manufacture.

In addition, vertical grooves are provided directly on the back surfaces of both sides of the outer lens to direct the lamp light, making the pilot display very clear and clearly distinguishable from sunlight, improving visibility.

In addition, since the case body has an entrance light gap with a lamp diameter of 7 mm and a front space that expands outward, even if the lamp mounting soft fitting is misaligned, the inner lens and pilot display window will still be able to accommodate the lamp. The light reaches the lens reliably, and the inner lens can be easily attached.

In particular, it is possible to combine the innovative display of the refracted light display method and the advantage of the direct light display method, in which visibility does not deteriorate even in sunlight, with a simple configuration.

Furthermore, since a single light source is used for direct light display in the pilot display section and refracted light display in the pictograph section, the configuration is simplified.
