JPH02136013A - Decorative plate frame for wiring accesories - Google Patents

Abstract

PURPOSE:To reduce the number of parts, to improve workability in assembly and to cut down the cost by using a decorative plate as an intermediate frame for function. CONSTITUTION:A decorative plate 2 is positioned by an abutted wall 12 against a plate frame 1. In the decorative plate 2 fixing pieces 22 are integrally provided extendedly to internal corner sections of a plate window 21. Fitting holes 23 are bored through these fixing pieces 22. Plate screws 13 are tightened up to a fitting frame of wiring accesories through these fitting holes 23, so that the decorative plate 2 can be secured to the fitting frame. Since the periphery of the decorative plate 2 is thus overlapped to the plate frame 1, the plate frame 1 can be pinched between the fitting surface such as wall, etc., and by fixing the decorative plate 2 to the fitting frame with plate screws 13, the plate frame 1 can be fixed simultaneously.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a decorative frame for a wiring device that decorates a mounting surface around a wiring device embedded in a mounting surface such as a wall surface.

[Prior Art] Conventionally, an embedded box such as a switch box is fitted into an embedded hole formed in a mounting surface such as a wall, and wiring devices such as switches and outlets are attached to the mounting frame fixed to the embedded box. It is considered to be installed. in this case,
In order to prevent the embedding hole and the mounting frame from being exposed and to obtain a desirable appearance, it is common to cover the parts other than the exposed parts of the wiring device with a decorative frame.

Generally, a decorative frame includes a decorative frame that covers the periphery of an embedding hole, a middle frame that holds the decorative frame between the mounting frame, and a decorative plate that covers the decorative frame and the surface side of the middle frame. here,
The inner frame and the decorative plate are connected using tapping screws that are inserted through the inner frame and screwed into the decorative plate.

[Problems to be Solved by the Invention] In the conventional structure described above, since the decorative plate and the inner frame, which are separate members, are connected by tapping screws, there is a problem that the number of parts is relatively large and assembly becomes troublesome. the result,
Parts costs and manufacturing costs also increase.

The present invention aims to solve the above-mentioned problems, and by using a decorative plate that also serves as the function of the inner frame, the number of parts can be reduced and workability during assembly can be improved.
It is an object of the present invention to provide a decorative frame for a wiring device with reduced cost.

[Means for Solving the Problems] In the present invention, in order to achieve the above object, a fixing piece with a mounting hole drilled in the inner corner of the plate window of the decorative plate is integrally extended, and the fixing piece is mounted through the mounting hole. By screwing the plate screws into fixed positions on the surface side, the plate is held between the decorative plate and the mounting surface.

[Function] According to the above configuration, the decorative plate can have the function of the inner frame, which was necessary in the conventional configuration to fix the plate frame to the mounting surface and hold the decorative plate. As a result, the inner frame becomes unnecessary, the number of parts associated with the inner frame is reduced, the number of parts is reduced, and costs can be reduced.

[Embodiment 1] The wiring device is attached to a mounting frame that can be attached to an embedded box, and the embedded box is housed in an embedded hole drilled in a mounting surface such as a wall surface. The mounting frame is set so that up to three wiring devices of unit size can be mounted. The embedded box, mounting frame, and wiring equipment are JIS
It is standardized by the Wiring Equipment Industry Association standards and is well known.

As shown in FIG. 1, the decorative frame includes a plate frame 1 disposed to cover the periphery of the embedding hole, and a decorative plate 2 disposed on the front side of the plate frame 1.

The plate frame 1 is formed along the periphery of the embedded hole, and the wiring device is exposed through an opening window 11 formed in the center of the plate frame 1. A projecting wall 12 is formed on the front surface of the plate frame 1 over the entire circumference.

The decorative plate 2 is a plate window 2 that exposes wiring devices.
1 at the center, the outer circumferential edge is formed in the same shape as the outer circumferential edge of the plate frame 1, and the inner circumferential edge is located inside the inner circumferential edge of the plate frame 1. This decorative plate 2 is positioned with respect to the plate frame 1 by a projecting wall 12. As shown in FIG. 2, fixing pieces 22 are integrally extended at the inner corners of the plate windows 21 in the decorative plate 2, and each of the fixing pieces 22 is provided with a mounting hole 23. By screwing the plate screw 13 into the mounting frame of the wiring device through the mounting hole 23, the decorative plate 2 can be fixed to the mounting frame. Here, the peripheral part of the decorative plate 2 is attached to the plate frame 1.
Since the plate frame 1 overlaps with the mounting surface such as a wall surface, the plate frame 1 can be held between the plate frame 1 and a mounting surface such as a wall surface, and by fixing the decorative plate 2 to the mounting frame with the plate screws 13, the plate frame 1 is also fixed at the same time. In addition, the plate screw 13 has a ring-shaped fastener 1 provided on the back side of the decorative plate 2.
4 is attached, and the plate screw 13 is held so that it does not fall off from the decorative plate 2. Here, since the plate screw 13 is inserted into the fixed piece 22, the plate screw 13 is sometimes tightened by making the fixed piece 22 made of glass fiber reinforced resin to prevent the fixed piece 22 from deforming. is desirable. For example, in the decorative plate 2, the portion corresponding to the fixing piece 22 is made of glass fiber-containing PC-
It is sufficient to perform two-color molding such that the part is made of ABS resin and the other parts are made of normal ABS resin. In such two-color molding, it is also possible to classify product types based on color combinations. Furthermore, if a rib 24 continuous to the fixing piece 22 is formed on the inner peripheral edge of the plate window 21,
The effect of preventing deformation of the plate frame 2 is further enhanced.

According to the above configuration, the plate frame 1 is sandwiched between the decorative plate 2 and the mounting surface such as a wall, and the plate screws 13 are used in the mounting frame of the wiring device, which is fixed to the mounting surface in advance. All you have to do is fix the decorative plate 2. Here, since the mounting hole 23 is formed so as to be exposed inside the plate window 21 of the decorative plate 2, the plate screw 13 can be tightened from the front of the decorative plate 2. In this way, plate frame 1
and the decorative plate 2 can be fixed to the mounting surface at the same time.

[Effects of the Invention] As described above, the present invention includes integrally extending a fixing piece with a mounting hole drilled in the inner corner of the plate window of the decorative plate, and inserting the plate screw into a fixed position on the mounting surface side through the mounting hole. The plate is held between the decorative plate and the mounting surface by screwing them together. In the conventional configuration, the plate frame is required to fix the plate frame to the mounting surface and to hold the decorative plate. The function of the inner frame can be given to the decorative plate, and as a result, the inner frame becomes unnecessary, and the number of parts associated with the inner frame is reduced, reducing the number of parts and reducing costs. It is. Furthermore, since the middle frame is not required, assembly work associated with the middle frame is no longer necessary, and workability is improved.
