BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide switch cover for improving operability by covering the slide switch.

[0002]

2. Description of the Related Art Conventionally, a slide switch is a component for controlling opening / closing of an electric circuit by sliding a knob which is an operating portion. Since such a slide switch tends to be miniaturized in recent years, a slide switch cover may be used for the purpose of improving the operability of the slide switch. The slide switch cover is used by covering the slide switch. That is, the slide switch cover, which has a size that is easy enough for an operator to operate, is covered on the operation part of the slide switch whose operability is reduced by downsizing, and the operation part of the slide switch cover is slid. By doing so, the operation portion of the slide switch slides in conjunction with each other.

[0003]

However, since the stroke of the operating portion is reduced due to the downsizing of the slide switch, the stroke of the operating portion of the slide switch cover is also shortened, which may deteriorate the operability. In other words, the force required to slide the operating portion of the small slide switch is relatively large, which makes it difficult to switch the slide switch, or the force may be relatively small and easily switches. If a large amount of force is required to switch the slide switch, the operability may deteriorate. In addition, when the switching of the slide switch is switched with a slight force, there is a possibility that the operator accidentally touches the slide switch cover and switches the slide switch without noticing it.

Further, due to the reduction of the stroke of the operation portion of the slide switch cover, it may be difficult to judge the open / closed state of the slide switch by the position of the operation portion of the slide switch cover.

Therefore, a first object of the present invention is to provide a slide switch cover capable of improving operability when switching the slide switch or preventing an erroneous operation caused by an operator's careless touch. To aim.

A second object is to provide a slide switch cover in which the open / closed state of the slide switch can be easily identified visually.

[0007]

In order to achieve the above object, the slide switch cover of the present invention is a fitting for fitting an operating portion having a protrusion to the protrusion of a slide switch provided slidably. The interlocking part having a hole formed therein and slidably provided, the cover operating part slidable by an external direct operation, and formed larger than the operating part, and the interlocking part. Sliding the operating portion with which the protrusion is fitted and sliding the cover operating portion in conjunction with each other, increasing the stroke amount of the cover operating portion with respect to the stroke amount of the operating portion, and And a conversion means for reducing the force required to slide the cover operating part for sliding the operating part with respect to the force required to slide the operating part by a direct operation.
Then, the converting means is a rack rack formed on the interlocking portion.
Formed on the cover operating portion and the first gear that engages with the
Pitch circle of the first gear, which engages with the rack gear
Has a larger pitch circle, is coaxial with the first gear,
And a second gear integrally formed.

The slide switch cover of the present invention configured as described above does not slide the operating portion of the slide switch directly, but slides in conjunction with the sliding of the cover operating portion via the conversion means. The projection of the operation unit is fitted in the fitting hole of the interlocking unit, and the cover operation unit is slid to indirectly slide the operation unit of the slide switch. The cover operating section is formed to be larger than the operating section, and the conversion unit visually checks the position of the cover operating section to increase the stroke amount of the cover operating section with respect to the stroke amount of the operating section, and electrically detects the slide switch. It is easy to determine the open / closed state. Further, the conversion means reduces the force required to slide the operating portion by sliding the cover operating portion to a force required to slide the operating portion by a direct operation.

FIG. 2A is a side sectional view and FIG. 2B is a side sectional view. As shown in FIG. 1 (b) and FIG. 2 (b),
The pins 25, 26, 27 project to both sides, and as will be described later, two link levers 22 engaging with each pin are provided on both sides in total. However, the configuration is not limited to this, and the pins 25, 26, and 27 may project only on one side, and the link lever 22 may have only one configuration.

The slide switch cover 20 is formed with a main body portion 20a for covering the slide switch 10 and a hole 23a for engaging the slide switch operating portion 11 protruding from a hole 20b formed in the main body portion 20a. An interlocking portion 23 that is slidably provided, a slide switch cover operating portion 21 that is slidably provided in the direction of arrow A and that can be operated from the outside, and a hole 29 for fitting so as to be rotatable around a pin 26. Of the slide switch cover operating portion 21 and the slide switch operating portion 1
1 has a link lever 22 for interlocking with the slide.

The slide switch cover 20 has a main body 2
The holding portion 20c formed on the slide switch 10a
Is covered from above the slide switch 10. As a result, the slide switch cover 20 itself is positioned with respect to the slide switch 10, and the slide switch 10 and the slide switch cover 2 are positioned.
It will not move relative to 0. As a result, as described above, the slide switch operating part 11 of the slide switch 10 is partially projected from the hole 20b formed larger than the stroke amount L11 of the slide switch operating part 11. The slide switch operating portion 11 protruding from the hole 20b is fitted into the hole 23a formed in the interlocking portion 23 as described above. This hole 23
a is of a size that allows the slide switch operating unit 11 to be easily inserted, and in particular, the length in the direction of the arrow A can be set by sliding the interlocking unit 23.
The slide switch 10 is also formed so as to slide, and thus allows the slide switch 10 to be electrically opened and closed.

U-shaped slits 28 and 30 are formed at both ends of the link lever 22. The slit 28 is rotatably engaged with the pin 25 of the slide switch cover operating portion 21, and the slit 28 a is rotatably engaged with the pin 25 of the interlocking portion 23. Also, the link lever 2
The slide switch cover 20 is provided in the hole 29 formed in
The pin 26 formed on the main body portion 20a of the

The slide switch cover operating portion 21 has a hole 20d formed above the slide switch cover 20.
It is provided so as to partially project from. The length of the hole 20d in the direction of the arrow A is such that the stroke amount L21 of the slide switch cover operating portion 21 can be secured so that the slide switch 10 can be opened and closed electrically in a relationship described later. There is. Further, the size of the slide switch cover operating section 21 is the same as the slide switch operating section 1
The size of the slide switch cover operating portion 21 is larger than that of the slide switch cover operating portion 21 because the operator can easily pinch the protruding portion of the slide switch cover operating portion 21.
However, for example, in FIG. 1 (a) and FIG. 2 (a), it can be easily visually confirmed whether it is on the left or right. Therefore, the identification of the open / closed state of the slide switch 10 is easier than the visual identification at the position of the slide switch operation unit 11.

An outline of switching of the slide switch 10 using the slide switch cover 20 having the above-described structure will be described.

For example, in FIG. 1A and FIG. 2A, by sliding the slide switch cover operating portion 21 on the left side to the right side, the link lever 22 rotates clockwise about the pin 26. By this rotation, the interlocking part 23 slides to the left. As a result, the interlocking unit 2
Slide switch operation part 1 fitted in the hole 23a of No. 3
1 is slid to the left, which is opposite to the direction in which the slide switch cover operating unit 21 slides, so that the slide switch 10 is switched.

Next, the hole 29 of the link lever 22 and the pin 2
5, the center distance L22 between the hole 29 and the pin 27, the stroke amount L21 of the slide switch cover operating portion 21, and the stroke amount L11 of the slide switch operating portion 11 will be described. In addition,
The center of the hole 29 of the link lever 22 and the center of the pin 26 are substantially the same.

The slide switch cover 20 of this embodiment
Is provided so that the link lever 22 satisfies L12 <L22. Therefore, the relationship between the strokes is L11.
<L21. That is, the slide switch cover 20 of the present embodiment uses the lever principle of the link lever 22 with the pin 26 as a fulcrum to slide with a force smaller than the force required to directly slide the slide switch operating unit 11. The switch cover operating part 21 is slid, and thereby the slide switch operating part 11 is slid. Therefore, less force is required for the operator to switch the slide switch 10.

In this embodiment, the force required to slide the slide switch cover operating portion 21 is smaller than that required to directly slide the slide switch operating portion 11, but the link lever is used as an example. 22 may be provided so as to be L12> L22, whereby the relationship between the strokes may be L11> L21. In this case, in order to slide the slide switch cover operating unit 21, the slide switch operating unit 1
It can be configured to require a force larger than that of directly sliding 1.

As described above, according to the slide switch cover 20 of this embodiment, the slide switch cover operating portion 21 is made larger than the slide switch operating portion 11, and the stroke amount of the slide switch cover operating portion 21 is slid. Since the stroke amount of the switch operating portion 11 is made larger, it can be easily visually confirmed when the open / closed state of the slide switch 10 is identified at the position of the slide switch cover operating portion 21.

The link lever 2 using the lever principle
Since the slide switch cover operating portion 21 and the slide switch operating portion 11 fitted into the hole 23a of the interlocking portion 23 are engaged with each other via 2, the link lever 22 moves to L1.
As 2 <L22, the force required for sliding the slide switch cover operating unit 21 can be made smaller than the force for directly sliding the slide switch operating unit 11, and the operability can be improved. it can. Further, when the link lever 22 has a configuration of L12 <L22, the slide switch cover operating portion 21
It takes a lot of force to slide the
It is possible to prevent an erroneous operation such as switching the slide switch 10 without noticing it by touching the slide switch cover operation unit 21. (Second Embodiment) A front view of a slide switch cover of the present embodiment is shown in FIG. 3 (a), and a side view thereof is shown in FIG. 3 (b).

As shown in FIG. 4B, the relationship between the radius L42 of the pitch circle of the gear 42 of the gear portion 42a and the radius L32 of the pitch circle of the gear 43 is L42> L32.
The gear ratio is L32 / L42. In the case of this embodiment, the force required to slide the slide switch cover operating unit 41 is L32 / L42 which is the force required to slide the slide switch operating unit 31. That is,
In the case of the present embodiment, when the force required to slide the slide switch operating unit 31 is 1, L32 / L4
Since 2 is 1 or less, the force for sliding the slide switch cover operating unit 41 is equal to the slide switch operating unit 3
Smaller than sliding 1 directly.

The gear ratio may be set to 1 or more, that is, the force for sliding the slide switch cover operating portion 41 may be larger than the force for directly sliding the slide switch operating portion 31.

The slide switch cover 40 of this embodiment
Other than the above, the configuration is basically the same as that of the slide switch cover 20 shown in the first embodiment, and thus detailed description thereof is omitted.

As described above, according to the slide switch cover 40 of the present embodiment, the slide switch cover operating portion 41 is made larger than the slide switch operating portion 31 and the slide switch cover 40 is provided, as in the first embodiment. Since the stroke amount of the cover operating portion 41 is set to be larger than the stroke amount of the slide switch operating portion 31, it is easy to visually confirm when the open / closed state of the slide switch 30 is identified at the position of the slide switch cover operating portion 41. it can.

The gear portion 4 having a gear ratio of L32 / L42
2a via the slide switch cover operating section 41,
Since the slide switch operating portion 31 fitted in the hole 43a of the interlocking portion 4 is engaged, the configuration is such that the gear ratio is 1 or less, so that the slide switch cover operating portion 41 of the slide switch cover operating portion 41 has a configuration similar to that of the first embodiment. The force required for sliding can be made smaller than the force for directly sliding the slide switch operating unit 31, and the operability can be improved. Further, by setting the gear ratio to 1 or more, the slide switch cover operating unit 41 is configured to require a large force to slide, and the slide switch is operated without the operator's mistakenly touching the slide switch cover operating unit 41. It is possible to prevent an erroneous operation such as switching 30.

[0034]

As described above, according to the present invention, the sliding portion of the operating portion of the slide switch slides in conjunction with the sliding of the cover operating portion via the converting means, and the fitting hole of the interlocking portion. The projection of the operation part is fitted to the cover, and the cover operation part is slid to slide the operation part of the slide switch. The force required for sliding is, for example, more than the force required for directly sliding the operating portion of the slide switch,
It can be set to be small. For this reason,
The operability when switching the slide switch is improved.
Further, the cover operating section is formed larger than the operating section, and the converting means increases the stroke amount of the cover operating section with respect to the stroke amount of the operating section. It becomes easy to judge the electrical open / close state.

Further, in the case where the converting means has a structure that requires a large force for sliding the cover operating part, it is possible to prevent an erroneous operation caused by an operator carelessly touching the cover operating part.
