Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a plate for a wiring device such as an outlet used in a house or the like.

[Background technology]

Generally, decorative plates for mounting parts of wiring devices such as electrical outlets are made of synthetic resin, but since this lacks fire resistance, metal plates have sometimes been used. However, metal plates give a cold appearance and are not suitable for residential use. Some attempts were made to eliminate the cold feeling by applying paint to the metal plates, but this had the drawback of being easily scratched. In addition, this product had the disadvantage that the screw head was visible on the surface and was conspicuous, resulting in a poor appearance.

[Purpose of the invention]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a wiring device plate that does not impair its appearance and has a fireproof structure.

[Disclosure of the invention]

The inventors have made extensive studies to achieve the above objectives. As a result, if a fire-resistant panel is interposed between the mounting frame that is attached to the wall or wiring equipment and the decorative plate made of synthetic resin, and a claw for attaching the decorative plate is provided on the back of the decorative plate, it is possible to The present invention was completed based on the discovery that these drawbacks could be overcome and good results could be obtained.

Therefore, the wiring device plate according to the present invention includes a fireproof panel, a decorative plate that covers the surface of the fireproof panel, a plate frame into which the fireproof panel and the decorative plate are fitted in an overlapping state, and a mounting frame, The decorative plate is provided with claws on the back surface of its periphery, and the fireproof panel is provided with holes through which these claws pass, and when the claws that have passed through the holes in the fireproof panel are engaged with the plate frame, The fireproof panel and the decorative plate are fixed to the plate frame, and the plate frame is overlapped with the mounting frame, and the fireproof panel is fixed to the mounting frame via the plate frame with screws. Therefore, the present invention is characterized in that the plate frame is fixed to the mounting frame together with the fireproof panel. Hereinafter, this will be explained in detail based on drawings showing examples thereof.

FIG. 1 is an exploded perspective view showing one embodiment of a wiring device plate according to the present invention. As shown in this figure, the decorative plate 1 is a synthetic resin molded body with a decorative finish such as coloring, and has two windows 2 formed in the center for exposing wiring devices such as electrical outlets. In the vicinity of the corners of the back surface and in the middle of each corner in the longitudinal direction, claws 3 extending outward are integrally provided. A fireproof panel 4 having windows 5, 5 similar to the decorative plate 1 is made of metal, and both side edges 6, 6 are bent vertically in the same direction. Through-holes 7 for receiving the claws 3 of the decorative plate are respectively formed, and screw-embedded screw through-holes 8 are provided on both sides of the two windows 5, 5. ing. The plate frame 9 made of synthetic resin has projecting pieces 11, 11 extending inward from both ends perpendicular to the longitudinal direction within the opening 10. As shown in FIG. On both sides of the projecting pieces 11, 11, there are gaps 12 into which the side edges 6, 6 of the fireproof panel 4 are fitted.
...(The one in the foreground is not visible in the diagram). These gaps 1 among the projecting pieces 11, 11
2... are claw locking portions 13 for locking the claws 3... of the decorative plate, and the protruding pieces 11,
It is somewhat longer and protrudes compared to the other parts of 11. The pawl locking portions 13 are adapted to lock the pawls 3 on the opposite side of the gap 12. A notch 1 for receiving a screw is provided in the center of the projecting pieces 11, 11.
4 and 14 are provided. The mounting frame 15 is designed to fit and fix wiring devices 19, 19 such as an outlet at the opening 17 in the center, and is designed to fit and fix wiring devices 19, 19 such as an outlet. The screw holes 16, 16 for attaching the plate frame are bored at both ends. In the figure, 18 is a screw.

When constructing such a plate for wiring devices, as shown in FIG. In this way, the fireproof panel 4
are placed on the protrusions 11, 11 of the plate frame. Next, insert the screws 18, 18 into the screw through holes 8, 8 of the fireproof panel as shown by the arrows in the figure.
8 and 18 in the notch 1 of the plate frame projecting pieces 11 and 11.
4, 14 through the screw holes 16, 16 of the mounting frame 15.
Screw it on. At this time, the plate frame 9 is fixed together with the fireproof panel 4 with its projecting pieces 11, 11 being sandwiched between the fireproof panel 4 and the mounting frame 15. Next, after inserting the claws 3 of the decorative plate 1 into the through holes 7 of the fireproof panel, the decorative plate 1 is secured to the claw locking portions 13, 13 of the plate frame protrusions 11, 11. It is fitted into the frame opening 10. At this time, the claws 3 on the back of the decorative plate enter the opening 10 while being pushed inward by the claw locking parts 13 and come out to the back of the opening 10, and then return to the original state by their own elastic force. By returning to , it is locked to the back surface of the claw locking portion 13 . The finished state is as shown in Figure 2.

In the embodiment, the wiring device plate according to the present invention has a shape for use with two connected wiring devices, but it can also be used for one wiring device or other connected devices. It may be in the shape of a cover plate.

The mounting frame may be attached to a wall surface or the like by screwing or by engagement.

〔Effect of the invention〕

As described above, the wiring device plate according to the present invention includes a fireproof panel, a decorative plate covering the surface of the fireproof panel, a plate frame into which the fireproof panel and the decorative plate are fitted in a stacked state.
a mounting frame, the decorative plate has claws on the back side of its periphery, and the fireproof panel has holes through which the claws pass, and the claws passing through the holes of the fireproof panel engage with the plate frame. The fireproof panel and decorative plate are fixed to the plate frame by being fixed to the plate frame, and the plate frame is overlapped with the mounting frame, and the fireproof panel is screwed to the mounting frame via the plate frame. Since the plate frame is fixed to the mounting frame together with the fireproof panel by being fixed with
Since the decorative plate can be made of synthetic resin, it becomes possible to present an appearance suitable for a house. Furthermore, because the plate frame is fixed from the fireproof panel rather than from the decorative plate, the screw heads are no longer exposed on the decorative plate surface, resulting in a very good appearance. This has the effect of eliminating the possibility of forgetting to put it on. That is,
By fixing the fireproof panel to the mounting frame through the plate frame, the plate frame and the fireproof panel are fixed to the mounting frame. There is a process of fixing it to the mounting frame, and there is no need to forget to insert the fireproof panel.
