Description

[Detailed Description of the Invention] The present invention relates to a rotary display device that displays vehicle speed and engine speed using colored zones.

Conventionally, display devices such as meters have been pointer type.

However, the above-mentioned conventional device has the disadvantage that it takes time to read the 5 readings because it is necessary to read the vehicle speed etc. from the position where the pointer is pointing.

In order to solve the above-mentioned drawbacks, the present invention fixes two rotating plates having fan-shaped opaque parts to a rotating shaft.

By arranging display boards with five colors on the back side of each rotary plate, and viewing the colors of these display boards from the circular arc band-shaped see-through part of the dial plate fixed to the main body.

18 (Can display the wide-angle zone of 5' or more in color,
For example, by being able to display 0 to 40/ix/h in white, 40 to 60 b/h in green, 60 to 100 b/h in yellow, and 100 b/h or more in red, you can easily measure the amount to be measured. The object is to provide a readable rotary display device.

The present invention will be described below with reference to embodiments shown in the drawings.

Fig. 1 shows an example of a speedometer; 21 is the speedometer body;
is a magnet that rotates in proportion to the vehicle speed.

3 is a rotor made of a non-magnetic material, and 4 is a rotating shaft to which the rotor 3 is fixed.

5 is a hair ring for controlling the rotational force due to the eddy current generated in the rotor 3 by the rotation of the magnet 2; 6;
is fixed to the main body 1 with a bearing for rotatably supporting the rotating shaft 4.

7 is fixed to the main body 1 by a dial plate, and as shown in FIG. It has a printed scale 7b ranging from O to 200 km/h.

Reference numeral 8 denotes a first rotary plate having a fan-shaped opaque portion 8a having an angular width of 12 (5') as shown in FIG. For example, the fan-shaped angle is made to match the scale angle of O to 100 b/h at the minimum scale position of Ob/h.

9 is a first display plate fixed to the main body 1 on the back side of the first rotating body 8;

As shown in Fig. 4, colors 9a to 9c correspond to angles <0 to 100 b/h (for example, O to 40 b/h are white, 4
0 to 60 b/h is printed in green and 6O to 100 h/h is in yellow), and has a transparent part or cutout part 9d in the same shape as the transparent part 7a in the range corresponding to 100 to 200 kIIi/h. There is.

Reference numeral 10 denotes a second rotary plate fixed to the rotary shaft 4 on the back side of the first display plate 9, as shown in FIG.
It has a fan-shaped opaque portion 10a with an angular width of
a is 10 at the minimum scale position of Oktt/h
It is made to match the angle of 0kjIt/h to 200h/h.

As a result, each opaque i of the first rotary plate 8 and the second rotary plate 10 is
The transparent portion 7a of the dial 7 is completely covered by the transparent portions 8a and 10a.

11 is a second display board fixed to the main body 1 on the back side of the second rotary plate 10;

As shown in Figure 6, <100kyIl/h~200b/h
A color 11a (for example, red) is printed in a range corresponding to .

In addition, it is preferable to unify the opaque part 8a=10a and the color of the dial 70 to black, etc., and the unsuitable transparent parts 8a, 10a and subsequent parts of each rotating plate 8, 100 should be made transparent (they may be cut out). Of course there is.

Next, the operation of the device of the present invention with the above configuration will be explained.

Now, the magnet 2 is not rotating, that is.

Consider the state of the Oh/h minimum scale display.

In this case, the colors 9a to 9c are the opaque parts 8 of the first rotary plate 8.
Since it overlaps with a, the color 9a is drawn from the transparent part 7a of the 1st dial 7.
~9c is not visible.

Also, since the first color 11a overlaps the opaque part 10a of the second rotary plate 10, the color 11a cannot be seen from the transparent part 7a, so the color is not visible in the range of O to 200b/h of the transparent part 7a of the dial T. I can't see it at all.

Next, considering the state of 1100k/h, the opaque portion 8a of the first rotary plate 8 is 100h/h to 200/ii/h
The color 11a is not visible from the transparent portion 7a of the dial 7 because it is blocked by the opaque portion 8a.

Moreover, since the opaque part 10a is in the range of 200b/h to 0&i/h, the transparent part 7a of the dial plate 7 has a range of O to 110b/h.
Colors 9a to 9c in the range of 0k/h are visible.

Next, considering the state of 11 I/h at 200 km, the opaque part 8a is in the range of 200 km to Oh/h, and the opaque part 10a is in the range of O to 100 kIII/h. Since it is located on the back side of the first display plate 9, the range of 0 to 100 b/h of the transparent part 7a of the first dial plate 7 is not obstructed by this opaque part 10a, and the first display plate 90 colors 98 to 9C is visible, and the range of 100 to 200 kyJ h of the transparent part 7a of the dial 7 is visible through the notch 9d of the first display board 9 to the second display board 110 colors 11.
I can see a.

Therefore, all the colors 9a to 9 can be seen from the transparent part 7a of the dial 7.
c11a is visible.

As described above, by using two rotating plates and two display plates, it is possible to display a wide-angle zone of 186) or more without being obstructed by each rotating plate.

The approximate vehicle speed can be easily and intuitively read by each color 9a to 9c and 10a.

For example, 0~40km/h is white, 40~60&m/
h is green, 60-100kjIi/h is yellow, 100&m/
H and above can be intuitively read in red.

In the above-described embodiment, the display is performed using only the colors of the display plates 9 and 11, but the pointer may be fixed to the rotating shaft 4 and the pointer display may also be used.

Furthermore, the shape of the opaque portions 8a and 10a does not have to be fan-shaped, but may be an arcuate band shape that can cover only the transparent portion 7a.

Furthermore, the transparent portions 7a of the dial plate 7 do not have to be in the form of equally spaced bands, but may be in the form of unevenly spaced bands that become wider and narrower as the speed increases.

Further, the color 11a of the second display panel 11 may be present on the entire surface, or conversely, it may be present only on the portion that can be seen through the transparent portion 7a.

Further, the colors 9a to 9c of the first display plate 9 only need to be present in the portions that can be seen through from the transparent portion 7a, and the first display plate 9 may have a transparent portion or a cutout portion 9d. Instead of providing the display panel, the sections other than the color sections 9a to 9c may be deleted to form a see-through section, resulting in a fan-shaped display board having only the color sections 9a to 9c.

Furthermore, instead of providing the dial plate 7 with a transparent section made of the transparent section 7a shaped like an arc band, a see-through section made of a notch shaped like a 5-circular band may be provided.

As mentioned above, in this invention, 18 (5
'Two rotating plates having the following opaque parts are fixed, and a first colored display plate and a second colored display plate having a transparent part are fixed to the main body on the back side of each rotating plate. The color of these display plates can be seen through the wide-angle circular arc band-shaped transparent part of the dial fixed to the main body, which is 186' or more, without being obstructed by the opaque part of each rotary plate. This has the excellent effect of being able to display the wide-angle zone in color, as well as making it possible to easily and intuitively read the approximate amount to be measured.
