When this case of the slider axes 40 is compared with a case of those protruded above the unit 22, there is no lowering of switching operability and the areas occupied by the switch button 16 and the switch unit 22 can be consequently reduced while the vertical thickness of the switch can be reduced to compose the small-sized and thinned switch for an onboard power window.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted power window switch used to automatically open and close the left and right front windows and rear windows of a two-door type and four-door type automobile.

[0002]

2. Description of the Related Art An automobile has a plurality of windows (windows), each of which can be electrically opened and closed, and can be opened and closed at a single position such as a driver's seat according to the number of windows. Collected multiple switch buttons in one place,
For example, it is arranged on the armrest inside the door.

On the other hand, since the outer dimensions of the vehicle body of an automobile are fixed, the space inside the vehicle is also limited, and since the plurality of switch buttons described above are installed in the limited space of the armrest, the above-mentioned switch is installed. The problem is that it should be small and compact.

By the way, since the switch button described above performs two operations of opening and closing with respect to one window, it is formed so that it can be pushed down and lifted up and down by a human finger. .

For example, since the driver sometimes opens and closes the window during driving, the switch button is formed large in consideration of operability, in particular, in order to smoothly operate the finger when the driver raises the window. However, it is preferable.

Therefore, as a single unit of a vehicle power window switch, the switch button is desired to be large in terms of operability, but it is desired to be formed compact and compact because it is arranged in a limited space like an armrest. Conflicting issues arise.

Conventionally, a switch used as a single unit for the vehicle-mounted power window switch of the above-mentioned example has a structure shown in FIG. 6, for example.

That is, an operating rod 53 is connected to a switch button 52 pivotably attached to a shaft 51, and the operating rod 5 is connected to the operating rod 53.
3, a switch unit 54 is disposed below the switch unit 54, and two slider shafts 55, 55 of a slider configured as a switching element inside the switch unit 54 are projected on the upper surface of the above-mentioned switch unit 54 so that these two The lower end of the above-mentioned operating rod 53 is inserted between the slider shafts 55, 55 of the operating rod 5 based on the above-mentioned operation of the switch button 52.
This is a structure in which one slider shaft 55 is operated and switched by the swinging of No. 3.

However, in the case of the above structure, since the slider shafts 55, 55 are projected to the upper surface side of the switch unit 54, the protruding amount H becomes bulky and the vertical direction of the switch cannot be made compact. I have a problem.

[0010]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle-mounted power window switch which can be made compact and compact without impairing the operability of the switch button.

[0011]

SUMMARY OF THE INVENTION The present invention is directed to a switch button which is pushed and pulled up and down from a neutral position by a human finger, and a slider which is arranged below the switch button and which reciprocates in a horizontal direction. Equipped with a slide switch unit that turns the switch on and off based on the movement of the switch, and an operating rod that transmits the operation of the switch button to the slide switch unit, by pushing and pulling the switch button from the neutral position A switch for a vehicle power window that opens and closes the seat window,

Is characterized by.

[0012]

According to the present invention, even if the switch button is formed slightly larger in terms of operability, the slide switch unit is arranged on the lower surface of the switch button, so that the occupied area is reduced in the flat area. Furthermore, since the slider shaft of the slide switch unit is extended in the lateral direction of the unit, there is no part (the main body of the slide switch unit) below the operating rod, and the switch button is located closer to the bottom of the slide switch unit. Can be provided.

As a result, the size of the switch button remains the same as that of the conventional one with good operability, and the area occupied by the switch button and the slide switch unit can be made small and the vertical thickness thereof can be made thin. As a single unit of the vehicle-mounted power window switch, it can be made thin and compact, so that it can be effectively used for vehicles.
