[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moderation mechanism of a switch device having a relatively large moderation range and a moderation range smaller than the range.

[0002]

2. Description of the Related Art In a blower switch device for an automobile, for example, an operation member is rotatably provided on a switch body, a changeover switch for switching between OFF and automatic operation (AUTO), and a low air flow (LO). There has been proposed a configuration in which a variable resistor for switching between high and high levels (HI) is provided, and the changeover switch and the variable resistor are operated by one operating member.

In this case, in the operation range of the operation member,
A relatively large sense of moderation is preferable in the operation range for operating the changeover switch, whereas a relatively small sense of moderation is preferable in the operation range for operating the variable resistor.

Therefore, as a configuration for obtaining such a sense of moderation, for example, a configuration shown in FIG. 5 has been considered.
FIG. 5 shows the moderation portion 1 in an expanded state. The moderation portion 1 is formed in, for example, an arc shape on a switch body (not shown), and the moderation portion 1 is provided with a compression coil spring 2.
The indenter 3 made of a ball pressed by the above is provided on the operation member (not shown) side.

The moderating portion 1 has a large moderating portion 4 having a relatively large first moderating concave portion 4a, and a plurality of moderating portions 4 projecting from the large moderating portion 4 toward the indenter 3 and smaller than the first moderating concave portion 4a. And a switching section 6 having a slope 6a formed between the large moderation section 4 and the moderation section 5 so as to connect them. And

In the above configuration, in the range in which the indenter 3 slides on the large moderation portion 4 of the moderation portion 1 in accordance with the operation of the operation member (large moderation region 7), a relatively large moderation feeling is shown. The changeover switch which does not operate is changed over, whereby the blower is turned “OFF”, “AUTO”, and “LO”.
Are switched to three stages. Also, in the range where the indenter 3 slides through the measure portion 5 through the switching portion 6 (measure region 8), the resistance value of the variable resistor (not shown) changes with a relatively small sense of moderateness, thereby causing air blowing. The device is switched between "LO" and "HI" in multiple steps.

[0007]

[Problems to be solved by the invention] In the above configuration,
In the moderation section 1, a switching section 6 is provided between the major moderation section 4 and the moderation section 5, that is, a moderation area 7 and a moderation area 8
Although the switching area 9 is provided between the two, the operation of the switching area 9 is a useless operation when viewed from the operation surface.

The switching section 6 is provided when the operating member is operated so that the indenter 3 slides from the large measure section 4 toward the small measure section 5 (in the direction of arrow A). ,
Assuming that there is no portion of the switching portion 6, the momentum when the indenter 3 crosses the mountain 4b next to the first moderation concave portion 4a corresponding to "AUTO" of the moderation portion 4 starts the first moderation portion 5. There is a risk of jumping over the second moderation concave portion 5a, which is required to prevent such a situation.

Therefore, the switching area 9 can be eliminated by omitting the switching section 6, but when the operating member is operated from the large-scale area 7 to the small-area area 8, the indenter 3 is moved to the small-scale area. There is a possibility that the first second moderation concave portion 5a of the portion 5 may be jumped.

Therefore, an object of the present invention is to eliminate the need for a switching region between the large-scale region and the small-scale region, and to reduce the small-sized indenter when operating from the large-scale region to the small-scale region. It is an object of the present invention to provide a moderation mechanism of a switch device which can prevent jumping of a moderation recess of a portion.

[0011]

In order to achieve the above object, the present invention provides a switch body, an operation member movably provided on the switch body, and one of the switch body and the operation member. Is provided in each,
A large moderation portion having a relatively large first moderation recess, a small moderation portion having a plurality of second moderation recesses smaller than the first moderation recess, and the switch body and the operating member. A first indenter that is provided so as to be pressed against the large-scale portion and the small-scale portion, respectively, and that relatively slides the large-scale portion according to the movement of the operation member; A second indenter that relatively slides the bar portion, and the first indenter slides the bar portion in accordance with the operation of the operating member. It is characterized in that the large degree region and the measure region where the second indenter slides in the small degree portion are continuous.

[0012]

When the operation member is operated, the first operation is performed in the moderation region.
The second indenter relatively slides on the measure portion in the measure degree region.

[0013] At this time, the large-scale portion and the large-scale portion are configured so that the large-scale region and the small-scale region are continuous when the operating member is operated. Since there is no portion corresponding to the switching area, there is no need to operate the switching area.

In addition, at this time, since the large-diameter portion and the first indenter sliding on the large-diameter portion are separate from the small-diameter portion and the second indenter sliding on the large-diameter portion, the first indenter with respect to the large-diameter portion is provided.
It is possible to separately adjust the pressure contact force of the indenter and the pressure contact force of the second indenter on the measure portion, and when operating the operating member from the large measure region to the measure region region side,
It is possible to prevent the second indenter from jumping over the second moderation recess of the moderation portion.

On the inner surface of “a”, a large measure portion 21 and a small measure portion 22 are formed in an arc shape in a state of being separated from each other.

As shown in FIG. 1 (a), the large moderation portion 21 has two relatively large first moderation recesses 23 and moderation peaks 23a. A flat portion 24 is formed on the right side of.

Further, as shown in the expanded state in FIG. 1B, the bar-shaped section 22 has a large number of second moderation recesses 26 smaller than the first moderation recess 23 on the right side of the flat section 25. It is formed so as to have a plurality.

On the other hand, two recesses 27, 28 are formed on the contact holder 16 side, and one of the recesses 27 has a compression coil spring 29, and thus a large-mode portion 21 and a flat portion. A first indenter 30 composed of a ball urged to press against 24 is provided, and the other concave portion 28 is pressed against the compression coil spring 31 and thereby the flat portion 25 and the bar portion 22. Is provided with a second indenter 32 composed of a ball biased to the second indenter.

Thus, the first indenter 30 slides on the large adjustment portion 21 and the flat portion 24 in accordance with the rotation operation of the operation member 15, and the second indenter 32 slides on the flat portion 25 and the small adjustment portion. In this case, the first indenter 30 is moved by the first indenter 30 in accordance with the turning operation of the operating member 15 as described later. Part 21
And a measure area 34 in which the second indenter 32 slides on the measure section 22 is continuous.

Next, the operation of the above configuration will be described. In the state where the operation member 15 is turned to the “OFF” position, FIG.
As shown by the solid line in (a), the first indenter 30 is
1 is in the first moderation concave portion 23 on the left side, and the second indenter 32 is pressed against the flat portion 25 as shown by a solid line in FIG. In this state,
Blower (not shown) with changeover switch 19 in the off state
Has stopped.

When the operating member 15 is turned from the "OFF" position in the direction of arrow B in FIG. 2, the first indenter 30 slides on the large-scale moderation portion 21 and the second indenter 32 Slides on the flat portion 25. At this time, the first indenter 3
0 slides the large moderation section 21 to switch the changeover switch 19 with a relatively large sense of moderation.

When the first indenter 30 crosses the moderation peak 23a on the right side of the large moderation portion 21 (see a two-dot chain line in FIG. 1A).
Then, the second indenter 32 enters the first second moderation concave portion 26 of the moderation portion 22 (see the two-dot chain line in FIG. 1B).

At this time, the slider 20b of the variable resistor 20 also slides with respect to the resistor 20a in accordance with the rotation of the operation member 15, but the resistance value of the variable resistor 20 is within the range of the moderation region 33. Is constant without change.

When the operating member 15 is further rotated from the "LO" position in the direction of arrow B, the first indenter 30 slides on the flat portion 24 in response to the operation, and the second indenter 32
Slides on the bar 22. At this time, the second
Of the variable resistor 20 changes with a relatively small sense of moderation when the indenter 32 slides in the moderation section 22, and the change in the resistance causes the blower to switch between "LO" and "H".
I ".

At this time, the movable contact 1 of the changeover switch 19
9b also slides with respect to the fixed contact 19a, but in this measure area 34, the state of the changeover switch 19 does not change.

When the operation member 15 is operated from the measure degree area 34 to the measure degree area 33, the operation is performed in the reverse motion.

According to the present embodiment, the moderation area 33
And the measure degree area 34 are continuous, and there is no portion corresponding to the switch area between the measure degree area 33 and the measure degree area 34, so there is no need to operate the switch area.

Further, in this case, since the large-diameter portion 21 and the first indenter 30 sliding on the large-diameter portion and the small-diameter portion 22 and the second indenter 32 sliding on the small-diameter portion are separate structures, Pressing force of the first indenter 30 against the portion 21 and the measure degree 2
2 can be adjusted separately from the pressing force of the second indenter 32 on the second indenter 32.
When operating from 3 to the measure degree area 34 side, the operating member 15 is moved by the second indenter 32 to the first second measure of the measure degree part 22.
Can be easily stopped at the position where it enters the moderation concave portion 26. Accordingly, it is possible to prevent the second indenter 32 from jumping over the first second moderation concave portion 26 of the moderation portion 22.

FIG. 4 shows another embodiment of the present invention, which differs from the above embodiment in the following points.

That is, in this embodiment, the second moderation recess 26 in the moderation section 22 is formed so as to start slightly from the left side in FIG.
And the measure degree area 34 partially overlap each other.

The present invention is not limited to the embodiments described above and shown in the drawings. For example, the large-scale portion 21 and the small-scale portion 22 are provided on the contact holder 16 side of the operating member 15 and Large measure section 21 and measure degree section 22
The first and second indenters 30 and 32 that are pressed against the
It may be configured to be provided on the side.

Furthermore, the present invention can be applied to a case in which the operating member 15 is slid in place of the case in which the operating member 15 is rotated with respect to the case 12. Further, the present invention is applied to a moderation mechanism of a switch device other than the blower switch device. Of course, it can also be applied.

[0038]

[Effects of the Invention] As described above, according to the present invention,
There is no need to operate the switching region because the large-scale region and the small-bar region are continuous and there is no portion corresponding to the switching region between the large-bar region and the small-bar region.

In addition, the large moderation portion and the first sliding portion
Since the indenter and the bar portion and the second indenter sliding on the bar portion have different configurations, the pressing force of the first indenter against the bar portion and the pressing force of the second indenter against the bar portion are different. Can be adjusted separately, so that the second indenter jumps over the second moderation recess of the moderation section 22 when the operating member is operated from the large moderation area to the moderation area side. Can be prevented.
