Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support structure for a decorative handle of a switch.

As interior decoration becomes more sophisticated, wiring devices are also required to be of high quality and have excellent operability.When it comes to switches that have a high-class image and are easy to operate, for example, design is important. One strategy is to unify the color of the plate and handle to make them more decorative.In terms of improving operability, for example, the handle can be made thicker so that it can be operated with just a light touch. A large handle may make it easier to operate even in the dark. Therefore, the present invention provides a switch having a structure in which the switch is divided into a handle and a decorative handle that engages with the handle, and the decorative handle is enlarged so that a reversing operation can be performed smoothly. With this structure, it is necessary to reliably reverse the switch no matter which part of the decorative handle is pressed, so a sufficient coupling structure is required for engagement between the switch handle and the decorative handle. For example, as shown in FIG. 1, protrusions B and C are provided on the back surface of the cosmetic handle A, and the structure is such that the protrusions B and C are engaged with the recess F1 hole G provided on the handle of the switch D.

In such a case, if the engaging protrusion C is chipped, the engagement between the decorative handle A and the switch handle D becomes unstable.

The present invention was made in view of the above-mentioned drawbacks,
To provide a high-grade wiring fixture that allows easy engagement between a cosmetic handle and a switch handle, and can withstand somewhat rough use and replacement of the cosmetic handle.

The present invention will be explained in detail below according to one embodiment thereof.

Reference numeral 1 denotes a mounting frame, which has a switch mounting through hole 2, a mounting screw 38 to the switch box 3, and a through hole 3b. Reference numeral 4 is a cut-and-raised part that supports the decorative handle 5, and has an arc-shaped 8 part 6 formed in the center. Reference numeral 7 is a screw hole in which the switch 8 is installed. 9 is a plate frame, IO is a decorative plate frame, and 11 is a middle frame. The plate frame 9, decorative plate frame 10, and middle frame 11 form a plate portion. The plate frame 9 and the mounting bracket 1 are connected to the protrusion 12 of the plate frame 9.
is engaged with the engagement hole 13 of the mounting bracket 1 and positioned. Note that 14.14 is the screw 15. of the middle frame 11. 15 is the hole into which it is screwed. That is, the decorative plate frame 10 is connected by connecting the inner frame 11 and the mounting bracket 1 with the screws 15. Reference numeral 16 denotes a handle of the switch 8, which is combined with the decorative handle 5. The handle 16 has a recess 18 except for a projection 17 in the center, and is fitted and coupled with a cylindrical projection 19 provided on the back surface of the cosmetic handle 5.

Thus, when the central rounded portion 6 of the support portion 4 of the decorative handle 5 formed by cutting and raising the mounting bracket 1 press-fits and locks the cylindrical protrusion 19 of the decorative handle 5 to the handle 16 of the switch 8. , comes into contact with the back surface 5a of the cosmetic handle 5. In other words, the portion corresponding to the upper and lower ends of the cosmetic handle 5 is 1
The decorative handle cut and raised from the accessory l is supported by the R section at the center of the support part 4, and is engaged and held by the handle 16 of the switch 8 at the center.

Therefore, even if the end of the makeup handle 5 is pressed,
If the decorative handle 5 is tilted and cannot be turned over smoothly, and if it is installed in a direction perpendicular to the longitudinal direction of the mounting bracket 1,
When the mounting bracket is tightened strongly to attach it to the switch box, the mounting bracket generally curves as shown in Figure 2, but as shown in Figure 4 of the present application, the bracket is cut and raised in one piece, so there is no possibility of bending. Nor.

FIG. 6(a) shows another embodiment, in which R-shaped protrusions 2o are provided at the upper and lower ends of the cosmetic handle in the longitudinal direction on the back surface of the cosmetic handle 5°. 20
The distal end portion 20a is configured to abut against the mounting fitting 1'' or a portion of the plate portion.

FIG. 6(b) shows an embodiment in which an R-shaped protrusion 21 is provided on the inner frame 11, and the R-shaped protrusion 21 of the inner frame 11 comes into contact with the back surface 5a of the cosmetic handle 5.

As described above, according to the present invention, the switch 8, the mounting bracket 1 for attaching the switch 8 to the switch box 3, the plate frame 9, the plate decorative frame 10, and the inner frame 1 are provided.
1 and an engaging means for engaging with the handle 16 of the switch 8 on the back surface, and the switch 8
A switch comprising a decorative handle 5 having a projected area larger than the projected area of , and a support portion of the decorative handle 5 is provided separately from an engaging means for engaging the handle 16 of the front i-switch 8. Because of this decorative handle support structure, the decorative handle 5 is made larger than the switch 8 to increase operability, and the decorative handle 5 is supported by a portion other than the engaging portion of the switch 8 with the handle 16. Even if the cosmetic handle 5 is made sufficiently large and the end thereof is pressed, no unnatural force will be applied to the cylindrical protrusion 19 on the back side of the cosmetic handle 5. 19 will not be damaged.

In addition, if the support part of the decorative handle 5 is formed by cutting and raising pieces extending perpendicularly to the longitudinal direction of the mounting bracket 1 at the upper and lower ends of the mounting hole 2 of the switch 8 of the mounting bracket 1, the mounting bracket is Even when the switch box is fastened and fixed to the switch box with the screws 3a, there is no possibility of the switch box being bent like in the conventional case.
