Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for attaching a flash plate that covers parts where wiring equipment such as switches and outlets are installed (including areas where wiring equipment will be installed later).

This type of flash plate is fixed to a support for a wiring device with screws, and its mounting structure has conventionally been as shown in FIGS. 1 to 4. That is, the support 1 has a wiring device fixing portion 2a and a wiring device caulking portion 2b, and has mounting holes 3 on the top and bottom for screwing to a box (not shown) buried in a wall surface, etc., and a plate surface. A plate mounting portion 4 including a step portion 4b bulging from the top and a plate mounting hole 4a drilled in the upper surface of the step portion is provided, and a flash plate 5 screwed to the support 1 has a support 1
A protrusion 6 having a screw insertion hole 6a is provided at a position corresponding to the plate attachment hole 4a, and a screw 7 inserted into the screw insertion hole 6a of this protrusion is screwed into the plate attachment hole 4a on the side of the support 1. The flash plate 5 is now installed.

By the way, the above-mentioned flash plate 5 is designed so that it can cover the surface of a box etc. buried in a wall surface etc. in a good manner.
Since its size, especially its width, is made larger than the width of the support 1, a hole is provided in the plate 5 through which the wiring device attached to the support 1 is exposed, and the fitting position of the plate 5 is determined by a wiring device (such as an outlet). There is no problem if it is done, but
In the case of a cover plate such as a blind plate structure (purely for the purpose of covering) that cannot be positioned with a wiring device that is installed in a place where wiring devices are expected to be installed in the future, it is not possible to simply cover it over the support 1. Since the positions of the plate attachment holes 4a and the screw insertion holes 6a are not determined, when attaching the plate 5 to the support 1 with screws, move the plate 5 in the left and right directions to align the screw insertion holes 6a and the plate attachment holes 4a. It is necessary to perform alignment, especially if the screw 7 is already attached to the screw insertion hole 6a of the plate 5 so that it will not fall out, find and position the screw tip so that it matches the plate attachment hole 4a of the support 1. Since the plate 5 has to be aligned, it is very difficult to attach the plate 5, resulting in a disadvantage that the work efficiency is significantly reduced.

This invention has been made in order to eliminate the above-mentioned conventional drawbacks, and an object of the present invention is to provide a flash plate mounting device devised so that the flash plate can be mounted to a support for wiring equipment with good work efficiency. .

Hereinafter, one embodiment of the present invention will be described with reference to the drawings in FIGS. 5 and 6. In the drawings, 1 indicates a stepped portion 4b protruding from the plate surface and a plate attachment hole 4a drilled in the upper surface of this stepped portion. A support having a plate attachment part 4 as shown in FIG.
This is a flash plate that is attached to a back surface protrusion 16 having a screw insertion hole 16a corresponding to the plate attachment hole 4a of the support 1, and a peripheral part of the screw insertion hole 16a, that is, the screw insertion hole 16a of the protrusion 16. guide portions 18a protruding from positions on both sides sandwiching the step portions 4b so as to fit into the step portions 4b;
18b is provided, and these guide parts 18a, 18b
The screw insertion hole 16a and the plate installation hole 4a are aligned by fitting the step into the plate installation part 4, and the screw 7 inserted through the screw insertion hole 16a is screwed into the plate installation hole 4a to support the flash plate 15. It is characterized in that it is screwed to 1.

The screws 7 are installed in advance in the screw insertion holes 16a of the flash plate 15 so that their screw tips are exposed on the lower surface of the protrusion 16 so that they do not fall out. When the guide parts 18a and 18b are placed over the plate attachment part 4 of the support 1 so as to fit into the stepped part,
The screw 7 is designed to match the plate mounting hole 4a, but even if the screw 7 is inserted from above the flash plate 15 and screwed in after the plate mounting hole 4a and the screw insertion hole 16a are matched. good. Further, the guide portions 18a and 18b may have a tapered surface in accordance with the shape of the plate attachment portion 4, or may be rib-shaped so as to simply contact the left and right step portions 4b of the plate attachment portion 4. Further, the plate is not limited to a cover plate, and may be a plate having a hole through which a wiring device is exposed.

The flash plate mounting device of the present invention is as described above, and includes a guide portion that fits into the stepped portion of the plate mounting portion that protrudes higher on the support side in the periphery of the screw insertion hole of the flash plate. Because of this, when screwing the plate to the wiring device support, the position of the screw hole can be easily determined and the flash plate can be installed quickly and accurately.
