Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch structure capable of easily removing a switch body from a fitting portion.

[0002]

2. Description of the Related Art When a switch body fitted to a fitting portion is removed, a flathead screwdriver or the like is inserted into a narrow gap between the fitting portion and the switch body to release the engagement. According to this method, there is a possibility that not only the switch body but also the design surface of peripheral parts may be damaged.

[0003]

However, it is necessary to remove the switch body in order to replace the parts attached to the switch, the illumination lamp, and the like, or to provide a means for fixing other parts in the fitting part of the switch body. In some cases, the fixing means cannot be removed without removing the switch body. The present invention has been made in view of the above, and an object of the present invention is to provide a switch structure that can be easily removed without damaging a design surface of a switch body and peripheral parts.

[0004]

According to a first aspect of the present invention, there is provided a switch structure, comprising: a pair of finger-hung recesses inside a hole facing a switch knob mounting hole formed in a switch body; After the switch knob is removed from the switch knob mounting hole, the switch body can be removed from the switch body fitting portion by a finger hooked on the finger hook recess.

[0005]

According to the above switch structure,
After removing the switch knob from the switch knob mounting hole,
A finger is hung on a pair of finger-hanging recesses formed inside opposing edge of the switch knob mounting hole, and the switch body is pulled out and taken out from the switch body fitting portion. Since the finger can be directly hung on the finger hook concave portion, the switch body can be easily removed without damaging the design surface.

[0006]

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of a switch body 1 with a part cut away, and FIG. 2 is a sectional view taken along line AA in FIG. 1 showing an assembled state of a switch knob 2. A hazard warning switch mechanism (not shown) is incorporated in the switch body 1. Switch body 1
The mounting hole 3 of the switch knob 2 of the hazard warning switch is formed on the upper surface of the hazard warning switch. A pair of finger hanging recesses 4 and 4 are formed inside opposed hole edges 3 a of the mounting hole 3. A flange 5 is formed around the upper surface of the switch body 1. The left and right side surfaces 6 of the switch body 1 are provided with elastic engagement pieces 7 having bent leaf spring members.

At the center of the mounting hole 3, a rectangular cylindrical knob holder 8 is formed. The upper end of the knob holder 8 protrudes from the mounting hole 3. On one of the side walls 9 opposed in the longitudinal direction of the knob holder 8, a notch 10
Are provided, whereby the engagement piece 11 is formed.
An engagement claw 12 is formed at the upper end of the outer surface of the engagement piece 11. On the outer surface of the other side wall 13 facing the side wall 9, an engagement protrusion 14 is formed at a position lower than the upper end.

The switch knob 2 is formed in a cap shape.
An engagement hole 15 that engages with the engagement claw 12 of the knob holder 8 and an engagement hole 16 that engages with the engagement protrusion 14 are formed. When the switch knob 2 is attached until it comes into contact with the upper end portion of the knob holder 8, the engagement claws 12 and the engagement protrusions 14 are elastically engaged with the engagement holes 15 and 16, respectively, and do not come off.

A fitting stepped portion 2 in which the flange 5 is fitted and received in the fitting concave portion 21 in which the switch body 1 is fitted.
2 are formed. An engaging claw 24 is formed at the lower end of the downward leg 23 provided on the fitting step 22. The switch body 1 is inserted from above the fitting recess 21.
When the flange 5 is pushed until it comes into contact with the fitting step portion 22,
Elastic engagement pieces 7 attached to both side surfaces 6 of switch body 1
Are brought into contact with the engaging claws 14 to bend and engage. As a result, the switch body 1 is fitted into the fitting recess 21.

In the above-described switch structure, it is necessary to replace parts such as a switch incorporated in the switch body 1, and the switch body 1 is removed from the fitting recess 21 or another article provided in the fitting recess 22. In some cases, it is necessary to remove the switch body 1 in order to remove the fixing means.

To remove the switch body 1, first, as shown in FIG. 3 (a), a flathead screwdriver 31 is inserted into the engagement hole 15 of the switch knob 2 projecting from the mounting hole 3. Since the engaging claw 12 formed at the distal end of the knob holder 8 protruding from the mounting hole 3 is engaged with the engaging hole 15, the engaging claw 12 is pressed and bent by the flathead screwdriver 31, It comes off from the engagement hole 15. Further, the switch knob 2 can be removed from the knob holder 8 by pulling up the switch knob 2 with the inserted flathead screwdriver 31. In this case, the design surfaces of the switch knob 2 and the switch body 1 are not damaged.

When the user puts his / her finger on a pair of finger hooking recesses 4 and 4 formed inside the opposed hole edge 3a of the mounting hole 3 from which the switch knob 2 is removed, and pulls up the switch body 1, the engaging claws 24 The elastic engaging piece 7 that engages with the first member is bent and disengaged, and can be taken out from the fitting concave portion 21. Since the finger can be directly hung on the finger hook recesses 4, 4, the switch body 1 can be easily removed without damaging the design surface.
