Description

[Detailed description of the invention] This invention relates to a display device for operating levers of audio equipment such as stereos, automobiles, and industrial machines such as measuring instruments, etc. In particular, a plurality of light emitting parts change the color of the emitted light depending on the position of the operating lever. This allows the amount of adjustment to be confirmed.

BACKGROUND OF THE INVENTION Control levers that move vertically or horizontally are often used to adjust the volume of audio equipment or to adjust the temperature of heaters, air conditioners, etc. installed on automobile dashboards.

Figure 1 shows a heater panel consisting of an operating lever 1 and a display section 3 for the purpose of adjusting the temperature of a commonly used automobile heater. It has a configuration in which two display boards 2a and 2b are arranged.

Note that two light sources with different emission colors are arranged on the back surfaces of the display boards 2a and 2b, and the irradiation light is emitted from the display boards 2a and 2b, respectively.
- The force operating lever 1 can be moved left and right along a guide groove 1a bored in the display section 2, and can be moved in either direction of the arrow indicated by the display panels 2a and 2b. The temperature can be adjusted by moving it.

However, in the conventional structure, there is no means to indicate the position of the operating lever, and therefore, when adjusting the temperature while driving at night, it may be confusing to know that it exists.

Also, even if you move the control lever, there is no way to indicate how much control it will give you.
It is difficult to select the appropriate position.

In the case of control levers for the purpose of adjusting the volume of audio equipment or the signal amount of other control devices, it would be extremely advantageous if the control amount could be immediately known, even though they are rarely operated in the dark. be.

Therefore, the purpose of this invention is to make it possible to easily confirm the position of the operating lever for adjusting the temperature of vehicle heaters, air conditioners, etc., adjusting the volume of audio equipment, and adjusting the signals of other control equipment. The amount of adjustment is displayed in color.

In order to achieve this objective, this invention includes an operating lever, two indicator lights with different luminous colors, an oscillator that has two oscillation outputs and uses the oscillation output to energize each of the above-mentioned lights, and a resistor. a variable resistor whose value can be adjusted to change the energization period of the two oscillation outputs of the oscillator in a state where the sum of the energization periods of both oscillation outputs is always constant; The resistance value of the variable resistor is adjusted using the variable resistor.

The embodiments shown in the drawings will be explained in detail below.

In Figure 2, 10.11 is an indicator light that is attached to a closed operation lever (not shown) for the purpose of temperature adjustment, volume adjustment, signal amount adjustment, etc. It may be a light bulb, a light emitting diode, etc. The colors are different, for example indicator light 1
0 is red, the indicator light 11 is green, etc.

Reference numeral 12 denotes a variable resistor, the slider 12a of which is adapted to adjust the resistance in conjunction with an operating lever.

This variable resistor 12 includes transistors Q1. It has the function of adjusting the oscillation conditions of an oscillator 13 composed of Q2, a resistor, and a capacitor, and the indicator lamps 10 and 11 are connected in series to transistors Qt and Q2, respectively.
As a result, the adjustment of the oscillation conditions causes a difference in brightness and nighttime.

Figure 3 shows the energization cycle of indicator lights 10 and 11.
If the energization period of the indicator light 10 is tl, and the energization period of the indicator light 11 is t2, then both energization periods t1. Since the sum of t2 is always constant, the variable resistor 12
If the slider 12a is in the middle, 1. = 12, and if the slider 12a is on the a side, the period is t2>t, so the lighting time of the indicator lamp 11 is long and the lighting time of the indicator lamp 10 is short.

That is, the display of the indicator light 11 is strong, and the display of the indicator light 10 is weak.

This means that as the operating lever moves, the controlled amount can be determined by the color of the indicator lights 10, 11.

In other words, when the operating lever is moved in either direction from the intermediate position, the color of the indicator light for one force becomes brighter and the color of the indicator light for the other force becomes brighter depending on the amount of movement. The amount of control is made clear by making it darker.

For example, if this device is applied to the control lever 1 of the automobile heater shown in FIG. 1, its position can be confirmed by the illumination of the indicator lamp 10. When the slider 12a is moved in any direction, the slider 12a moves in response, and as a result, the indicator lights 10 and 11 change color in accordance with the control amount. Value selection becomes possible.

In this case, the indicator light 10.11 may be formed with a housing at the end of the operating lever 1 and housed in the housing. They may be separated and stored separately.

The present invention can be applied not only to automobile heaters but also to volume adjustment or control equipment for audio equipment.

FIG. 4 shows an embodiment in which the oscillator 13 is replaced by another oscillator 13' connected in series with an inverter.
Since two oscillation outputs with opposite polarities are obtained at the X point and the Y point, these oscillation outputs cause the above-mentioned indicator light 10.1.
1 and by moving the slider 12a of the variable resistor 12, the same effect as in the above example can be obtained.

Note that R1 and R2 are current control resistors, and Dlt D2 is a backflow prevention diode.

In this way, by obtaining two oscillation outputs from one oscillator and changing the energization period of these oscillation outputs by changing the resistance value of the variable resistor, an effect is created in which if one force becomes longer, the other force becomes shorter. If it can be obtained, it can be implemented regardless of the form of the oscillator.

As is clear from the above explanation, this device is equipped with two indicator lights that emit light of different colors on the operating lever, and the illumination of these indicator lights indicates the position of the operating lever, and the resistance that accompanies the movement of the operating lever is Each of the indicator lights is energized by the oscillation output of an oscillator whose value is adjusted so that the energization period of the two oscillation outputs changes in such a manner that the sum of the energization periods of both oscillation outputs is always constant. Because it is,
The position of the control lever is obvious at a glance, and since the luminous intensity of the two indicator lights with different luminescent colors changes in inverse proportion to each other as the control lever is moved, the degree of adjustment can be visually recognized. .

Temperature adjustment operation especially for vehicles? When applied to the bar, it is effective because its position can be easily confirmed even when driving at night, and the amount of adjustment can be visually determined.

Although the previous explanation mainly focused on an example provided with an operating lever, the same implementation is possible even with a rotary volume knob.
