Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This output relates to a bar graph display device installed in speedometers, tachometers, and other various devices for vehicles such as vehicles.

[Conventional technology]

In addition to pointer-indicating instruments that have been widely used in the past, in recent years, instruments that display measured quantities using display devices such as LCDs and fluorescent display tubes have become widely used. Ta.

Among them, Utility Model Application No. 57-126070, Utility Model Application No. 59
Displays using bar graphs are well known, such as those disclosed in Japanese Utility Model Publication No. 31018 and Japanese Utility Model Application Laid-Open No. 59-32920.

[Problems with conventional technology]

Some bar graph displays are known, such as ones that change from a non-emitting state to a luminous state, and ones that change the length of the display by changing from an inconspicuous color or colorless to a conspicuous color. Not only does the length change, but for example, in the case of vehicle speedometers, the display color corresponding to speeds of 100 km/h or more is red, which is different from other colors such as orange or green for speeds of 100 km/h or less, to make it more noticeable. There are some.

However, with the above-mentioned devices, it is difficult for the user to strongly recognize changes in the measured quantity, and in particular, taking the above-mentioned speedometer as an example, changes in the display in the range of less than 100 km/h are large (steep) changes. Other than that, there is a disadvantage that it is difficult to understand unless you look closely.

Also, Japanese Patent Publication No. 58-4346, Japanese Patent Publication No. 53-
As in Publication No. 94797 and Publication of Utility Model Application No. 60-29228,
There is also a display in which the display area is gradually enlarged from one end to the other, making it easier to recognize changes in the displayed value, but since it is a single bar graph display, The degree of appeal to users is small,
In particular, there are problems in that changes within the same stage are still difficult to recognize, and changes in the display are difficult to see smoothly.

In addition, as in Japanese Utility Model Application Publication No. 57-170773, there is a device that displays illumination by arranging display sections side by side, but since there is a target to be measured corresponding to each display section, this is also a single bar. There is no difference in the degree of appeal to the user from what is displayed graphically.

Furthermore, the conventional design of the instrument display surface, which is often seen by users, is almost uniform, which is another disadvantage.

[Purpose of the invention]

The present invention has been made in view of the above, and it is an object of the present invention to provide a bar graph display device that makes it easy to recognize changes in measured quantities and that is slightly different in design from conventional devices.

[Summary of the invention]

In order to achieve the above object, the present invention displays a predetermined measured quantity in a plurality of bargraphs, in which a plurality of bargraph display sections having substantially the same shape and having the same function are arranged in parallel, and the plurality of bargraph display sections are arranged in parallel. The bar graph display section is characterized in that it has at least a portion where the interval between adjacent bar graph display sections gradually narrows from one end side to the other end side in the display length direction.

〔Example〕

FIG. 1 is a front view of a display device showing an embodiment of the present invention.

In the figure, numeral 1 is a display board, which in this case displays a vehicle instrument. This display board 1 includes an engine tachometer 2, a speedometer 3, an engine coolant temperature gauge 4,
The remaining fuel gauge 5 and trip totalizer 6 are displayed, the engine tachometer 2 and the remaining fuel gauge 5 are bar graph zone displays, the temperature gauge 4 is a bar graph segment display, the speedometer 3 and trip totalizers. A total of 6 are digital displays. Among these, the present invention is applied to the tachometer 2. That is, tachometer 2
7 bar graph display section 2 to indicate the rotation speed
A, 2B, 2C, 2D, 2E, 2F, and 2G are arranged side by side to create a new design, and the spacing between adjacent bar graph display sections 2A to 2G is 7A, 7B, 7C, and 7D. ,7E,7
F is formed so that the width becomes gradually narrower from the left end corresponding to low rotation toward the right end corresponding to high rotation. In addition, each of the bar graph display sections 2A to 2G is formed by arranging a large number of small display elements in succession in the display length direction, and the display elements are arranged continuously in accordance with the rotation speed from the low rotation side to the high rotation side. The rotation speed is indicated by a change in the display length formed by the body, and the bar graph display sections 2A to 2G display the same change in display length.

The spacing between adjacent display elements of each bar graph display section 2A to 2G is generally formed in the same color as the display board 1, and the shape is on the low speed side of the spacing between bar graph display sections 7A to 7F. Also, as mentioned above, the width of the bar graph display section 2A
~2G has the same effect, that is, by always changing the display length at the same time, the change in display length of the bar graph display sections 2A to 2G can be felt more smoothly. I have to. Note that 8 is the scale of each display and letters, numbers, and marks corresponding to the scale.

According to the present embodiment described above, not only the display length but also the interval between adjacent bar graph display sections can be adjusted.
As the rotation speed increases from the low rotation side to the high rotation side, the display area in the direction perpendicular to the display length direction gradually increases, and the interval between the display sections also gradually narrows, and the segments displayed by the bar graph display sections 2A to 2G. The contrast between the dark and dark intervals 7A to 7F gives a strong impression to the user, and allows the user to easily recognize changes in the display. By arranging the bar graph display sections 2A to 2G side by side, it is possible to make a strong appeal to the user and achieve smooth display changes. Since the spacing between the matching bar graph display sections 7A to 7F is narrower than on the low rotation side, changes in the display appear smooth, and since the overall width of the display section 2 of the tachometer is constant, changes in the display appear as if they were on the low rotation side. It feels even smoother, like it flows.

Furthermore, if the bar graph display part corresponding to high revolutions, for example 6500 revolutions or more, is made red and the other part green, etc., not only will the color change, but the red display area will become larger, increasing the warning effect. can also be made large.

FIG. 2 shows a second embodiment of the present invention, and is a front view of only the bar graph display section.

In this embodiment, three bar graph display sections 9A, 9B, and 9C are arranged side by side, and the intervals 10A and 10B between adjacent bar graph display sections are set on the lower end side. It is wide in the range 11 and narrow in the upper end side range 12, which are constant, and in the central range 13, the width gradually becomes narrower in four steps. This embodiment also provides the same effects as those of the above embodiment.

The above embodiments can be applied to various display devices such as LED display, fluorescent display tube display, magnetic reversal display, etc., and can also be applied to various displays other than vehicle engine revolution meters. can do.

〔Effect of the invention〕

According to the present invention, in order to display a predetermined measured quantity, a plurality of bar graph display sections having substantially the same shape and the same function are arranged side by side, thereby providing novelty in design and replacing the conventional uniform display. It is possible to expect a smooth display change by making the display length different, and by having a part where the interval between adjacent bar graph display parts gradually narrows from one end of the display length to the other end. This has the effect of making it easier for the user to recognize.
