Is provided with a rectangular opening 11 for exposing the functional surface (the operation handle 72 of the tumbler switch S) of the wiring device (the tumbler switch S in the illustrated example) to the front side. In addition, a belt-like fixed beam portion 12 and a movable beam portion 13 are provided on the periphery of the opening portion 11 so as to face each other with the opening portion 11 interposed therebetween. The movable beam portion 13 is separated from one side frame piece 11b of the pair of side frame pieces 11a and 11b facing each other with the opening 11 of the plate frame main body 10 interposed therebetween, and the side frame piece together with the fulcrum portion 14 at both ends thereof. 11b is formed integrally and swingably. Here, the synthetic resin forming the plate frame main body 10 including the movable beam portion 13 and the fulcrum portion 14 is a flexible material, and the movable beam portion 13 supports the fulcrum portion 14 with respect to the plate frame main body 10. It can be bent freely.

  On the other hand, on the surface of the fixed beam portion 12 and the movable beam portion 13 on the opening portion 11 side, a pair of locking claws projecting one by one from both side surfaces of the instrument body 70 of a tumbler switch (hereinafter abbreviated as “switch”) S. A pair of locking grooves 12a and 13a (not shown) to be locked is provided in each of two pairs, for a total of four. That is, by engaging the locking claws provided on the instrument main body 70 with the pair of locking grooves 12a and 13a in each set, the instrument main body is attached to the plate frame main body 10 with the operation handle 72 exposed from the opening 11. 70 can be attached. That is, in the present embodiment, the pair of locking grooves 12a and 13a correspond to the attaching means.

  The fixed beam portion 12 is provided with three tool removal holes (not shown) penetrating from the front side of the plate frame main body 10 between the respective locking grooves 12a at equal intervals, so that a screwdriver or detachment is possible. If a tip part of a dedicated jig or the like is inserted into the tool removal hole and the tool body 70 is pushed toward the movable beam part 13 by the tip part of the jig, the movable beam part 13 is moved with a slight force by the lever principle. The device main body 70 can be detached from the plate frame main body 10 by unlocking the locking groove 12a on the fixed beam portion 12 side and the locking claw of the device main body 70.

  By the way, the dimension of the opening 11 is the instrument body (hereinafter referred to as “one module instrument”) formed to the reference dimension when the dimension of the instrument body 70 of the wiring instrument (switch S) shown in FIG. The dimension is equal to approximately twice the dimension in the short width direction of 70. In other words, the dimension is such that two instrument main bodies 70 of one module can be connected in the short width direction. . Similarly, the pitch of the locking grooves 12a and 13a provided in the fixed beam portion 12 and the movable beam portion 13 of the plate frame main body 10 is equal to the pitch of the locking claws protruding from the side of the instrument main body 70 of one module. Are equal. In addition, the said reference dimension should just be set to an appropriate value, and if it is a wiring apparatus suitable for such a reference dimension, it can attach to the plate frame 1 in common. The side frame pieces 11a and 11b of the plate frame main body 10 have a box screw insertion hole 15 through which a box screw (not shown) for attaching the plate frame 1 to an embedding box (not shown) is inserted. Is provided.

  By the way, on the four side frame pieces 11a to 11d surrounding the opening 11 of the plate frame main body 10, a flat plate-like connecting projection 16 and a rectangular connecting groove portion having a dimension that allows the connecting projection 16 to engage with the concave and convex portions. 17 are arranged in parallel. Here, the positional relationship between the connecting projection 16 and the connecting groove 17 in each of the side frame pieces 11a to 11d is the same.

  Therefore, for example, when two plate frames 1 are arranged side by side on the construction surface, the connecting projection 16 projecting from the side frame piece 11c of one plate frame 1 is used as the side frame piece 11d of the other plate frame 1. 1, the side frame piece 11 c of one plate frame 1 and the side frame piece 11 d of the other plate frame 1 are brought into contact with each other and adjacent to each other as shown in FIG. The plate frames 1 can be aligned and connected in a good-looking manner. Moreover, since the two plate frames 1 are connected by the concave-convex engagement between the connecting projection 16 and the connecting groove portion 17, the plate frame 1 is not displaced during construction or use.

  By the way, at the four corners of the plate frame main body 10, there are provided locking holes 18 into which the protruding pieces 31 protruding from the back of the decorative plate 3 are inserted and locked. The decorative plate 3 can be detachably attached to the front side of the plate frame 1 by inserting and locking the protruding pieces 31.

  On the other hand, a mounting member (hereinafter referred to as “mounting frame”) 2 located at the left end in FIG. 1 is for mounting an embedded type outlet C, and is formed by punching a metal plate into a substantially circular shape at the center. The attachment window 20 is formed in a substantially square shape with an opening, and a pair of leg pieces 21 are extended from the periphery of the attachment window 20 toward the rear. Further, the body 22 of the outlet C made of a synthetic resin molded product is fixed to the tip of each leg piece 21. The body 22 holds a blade receiver (not shown) that receives the contact of the plug and a grounding blade receiver 23 that contacts the ground electrode of the plug. The vertical and horizontal dimensions of the mounting frame 2 are substantially the same as the vertical and horizontal dimensions of the plate frame 1.

  The decorative cover 6 is formed by integrally forming a bottomed cylindrical cover main body 60 and an outer casing 61 having a substantially square shape in plan view formed on the front surface of the cover main body 60 as a synthetic resin molded product. A recess 62 into which the plug is fitted from the front is formed on the front surface of the plug, and a pair of pin insertion openings 63 into which the plug contacts are inserted is formed on the bottom surface of the recess 62 (see FIG. 2). ). Then, the outlet C is assembled by coupling the cover body 60 to the body 20 by an assembly screw 64 inserted through a screw insertion hole (not shown) provided in the center of the bottom surface of the recess 62. It should be noted that the outer shape and dimensions of the outer flange portion 61 are substantially matched with the opening window 30 of the decorative plate 3.

  Further, each side of the mounting frame 2 is formed with a connecting projection 2a and a connecting groove 2b each having a shape and size that can be fitted to each other, and a plurality of mounting frames 2 or mounting frames 2 and plate frames 1 are formed. Are arranged side by side, the connecting projection 2a (or the connecting projection 16 of the plate frame 1) of the adjacent mounting frame 2 and the connecting groove 2b (or the connecting groove 17 of the plate frame 1) are engaged. Accordingly, the adjacent mounting frames 2 (or the mounting frame 2 and the plate frame 1) can be aligned and connected in a good-looking manner.

  The decorative plate 3 is formed in a long, substantially dish shape covering the front surface of the mounting members (plate frame 1 and mounting frame 2) with an insulating synthetic resin, and faces the mounting members and has the same shape and dimensions. The substantially square opening window 30 which has is arranged in parallel at equal intervals in the longitudinal direction. Therefore, the decorative plate 3 is covered from the front on the three mounting members (two plate frames 1 and one mounting frame 2) embedded and arranged so as to be connected to the construction surface such as a wall surface, and the back side of the decorative plate 3 The decorative plate 3 can be attached to the front surface side of the mounting member by inserting and locking the protruding pieces 31 projecting from the respective locking holes 18 of the two plate frames 1. Further, the functional surfaces of the wiring apparatus (the operation handle 72 of the switch S and the recess 62 of the outlet C) are exposed forward from the respective opening windows 30 of the decorative plate 3 attached to the attachment member (see FIG. 2). .

  Here, the opening window 30 of the decorative plate 3 is set to have a size larger than the functional surface of the wiring device. For example, the operation window 72 around the switch S in the opening window 30 has other than the functional surface of the wiring device. Although an exposed space is generated, this space can be closed by the decorative covers 4, 5, 6 (see FIG. 2).

  The decorative covers 4 and 5 are made of a synthetic resin molded product having a substantially rectangular flat plate shape. Exposed windows 40 and 50 for exposing the operation handle 72 of the switch S are provided at the center. However, one of the exposure windows 40 has a shape and size that allows one operation handle 72 to be exposed, and the other of the exposure windows 50 has a shape and size that allows two operation handles 72 to be exposed. In addition, a plurality of locking portions 41 having engaging protrusions 41 a protruding outward are provided on the back side of the decorative covers 4 and 5.

  Thus, if the decorative plate 3 is attached to the front surfaces of the plate frame 1 and the mounting frame 2 connected to each other, and the decorative covers 4 and 5 are fitted to the opening window 30 of the decorative plate 3, the locking portion 41 becomes the opening window. The space formed around the operation handle 72 of the switch S in the opening window 30 is closed by the decorative covers 4 and 5 (see FIG. 2). . Note that the opening window 30 corresponding to the attachment frame 2 is closed by the decorative cover 6 when the decorative plate 3 is attached.

  Thus, in the conventional example shown in FIG. 3, it is necessary to separately prepare a plurality of types of decorative plates whose opening windows match the outer shape and dimensions of the functional surface of the wiring device. In addition, there are problems such as an increase in the number of dies and the like, resulting in an increase in manufacturing cost and an increase in labor for inventory management. On the other hand, in this embodiment, the plurality of opening windows 30 of the decorative plate 3 are formed in the same size and shape, and the opening windows 30 in which the functional surfaces of the wiring device are exposed out of the plurality of opening windows 30. Since the interior space is closed with the decorative covers 4, 5, 6, the shape of the opening window 30 depends on the combination of the number and type of wiring devices attached to the connecting members (plate frame 1 and mounting frame 2) connected to each other. In addition, it is not necessary to prepare various types of decorative plates having different dimensions, and the manufacturing cost can be reduced as compared with the conventional example. In addition, it is conceivable to match the functional surface of the wiring device to the shape and size of the opening window 30 of the decorative plate 3, but in this case, the shape and size of the functional surface of the wiring device is regulated by the opening window 30 to design and design. As described above, the use of the decorative covers 4, 5 and 6 has an advantage that the degree of freedom in designing and designing the wiring device is increased. In addition, although the case where three attachment members were connected was illustrated in this embodiment, even when connecting 2 or 4 or more, it can respond easily by changing the dimension of the decorative plate 3.

It is a disassembled perspective view which shows embodiment of this invention. It is a front view same as the above. It is a front view of a prior art example.
