SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention provides an emergency button switch cover structure which can be reused without being damaged by being easily detached from the switch case even if an excessive force is applied to the switch cover. The purpose is to realize.

[0007]

According to a first aspect of the present invention, there is provided an emergency button switch cover structure in which a switch case and a switch button for opening and closing the switch are provided in a switch case. A switch cover 3 for protecting the switch button 28 outside the
In the emergency button switch 1 provided so as to be openable and closable, the switch cover 31 has a U-shaped frame member 33.
And a window member 34 made of a plate-shaped transparent material through which the switch button 28 can be seen.
The window member 34 and the window member 34 are provided with support means for detachably supporting the window member 34 on the frame member 33.

Further, the supporting means for supporting the window member 34 on the frame member 33 is provided inside the frame member 33 and in the U direction.
Engagement pieces 35, 35 ', 36, 36' that can insert and support the window member 34 in both legs,
Protrusions 37, 37 'for fixing the window member are provided, and the window member 34 has cutouts for avoiding engagement pieces 36, 36' formed on both legs of the frame member 33 when inserted into the frame member 33. Parts 38, 38 'and a projection 3 for fixing the window member provided on the frame member 33 when the window member 34 is assembled to the frame member 33.
The recesses 39 and 39 'are formed so as to engage with the first and the third recesses 37 and 37'.

With this configuration, since the frame member and the window member of the switch cover are not fixed by an adhesive, heat welding, or the like, the frame member can be elastically deformed. For this reason, if an excessive force is applied to the switch cover, the switch cover is easily detached from the bearing portion, so that the switch cover is not damaged.

[0010]

FIG. 1 is a view showing a state in which an embodiment of an emergency button switch cover structure according to the present invention is applied to an emergency button switch, wherein (a) is a front view and (b) is (a).
It is sectional drawing in the BB line of the figure. In the figure, reference numeral 20 denotes a switch case, which is attached to an insulating substrate 21. The switch board 20 is provided on the insulating substrate 21.
A switch 24 having a slider 22, a switch housing 23, a fixed contact (not shown) and a movable contact (not shown) is mounted substantially at the center.

A bearing member 25 is attached to the inside of the switch case 20 by a screw 26. The switch button 28 having a shaft 27 formed parallel to one side of the bearing member 25 is attached to the bearing member 25. Slider 2 of switch 24
2 is swingably mounted so as to be pressed. A bearing 30 having a bearing hole 29 penetrating left and right is formed outside the switch case 20, and a switch cover 31 is provided on the bearing 30 so as to be openable and closable by a shaft 32. The above is the same as the conventional example described with reference to FIG. The feature of this embodiment is that the switch cover 31
Is different. Next, the switch cover 31 will be described.

The switch cover 31 includes a U-shaped frame member 33 made of an opaque material, and a transparent window member 34. As shown in FIG. 2, the frame member 33 has a U-shaped bottom 33a and both legs 33b, 33c.
Has an L-shaped cross section and is recessed so that the back surface can accommodate the window member 34. Horizontally extending engagement pieces 35, 35 ', 36, 36' are formed so that the window member 34 can be inserted and supported in the U-shaped corners and both legs of the depression. Are formed with projections 37 and 37 'for fixing the window member 34 when the window member 34 is inserted.

As shown in FIG. 3, the window member 34 is formed in a size that can be accommodated in the recess of the frame member 33, and the engaging pieces 36, 36 'of the frame member 33 are avoided on both sides thereof when assembling. Notches 38, 38 'are formed, and fixing projections 37, 37' formed on the frame member 33 to prevent the frame member 33 from falling off after assembly.
Are formed.

The frame member 33 and the window member 34 thus formed are assembled as shown in FIG. That is, first, as shown in FIG. 3A, the notch portions 38, 38 'of the window member 34 are engaged with the engagement pieces 36, 36' of the frame member 33.
Is placed in the recess of the frame member 33 so as not to interfere with the frame.
Next, the window member 34 is slid while being pressed in the direction of the bottom side of the frame member 33 (the direction of arrow A) (b). , 3
5 'and both sides of the window member 34 are
3 are engaged with the engagement pieces 36, 36 'of both legs. At the same time, the concave portions 39, 39 'of the window member 34 are engaged with the fixing projections 37, 37' of the frame member 33.

The thus assembled switch cover 31 is assembled by engaging a shaft 32 with a bearing 30 of the switch case 20, as shown in FIG. The switch cover 31 of the present embodiment thus assembled to the switch cover is released from the switch case 20 when the switch button 28 is to be pressed in an emergency, but at that time excessive force is applied to the switch cover 31. When added, the frame member 33 is elastically deformed and separates from the bearing 30 of the switch case 20. Therefore, it is detached but not damaged, and can be reused.

[0016]

According to the emergency button switch cover structure of the present invention, since the frame member 33 and the window member 34 are not joined by an adhesive or welding, the frame member 33 can be elastically deformed. Even if an excessive force is applied to the switch cover 31, the frame member 32 is elastically deformed and can be detached from the bearing portion 30 of the switch case 20, and is not damaged.
