【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

The fitting (1) of the wiring device includes a pair of complementary plate-shaped fitting portions (2) and (3) facing each other, and an arc-shaped joining portion that joins these fitting portions to each other. Equipped with (4). The fitting portions (2) and (3) are expanded at the joint portion (4) within a range where elasticity can be restored, and are elastic at the opening edge (7) of the opening portion (6) of the mounting wall (5). Are fitted together to temporarily attach the fixture (1) to the attachment wall (5). The joint portion (4) spreads the fitting portions (2) and (3) substantially parallel to each other and elastically fits the opening edges having different thicknesses. Further, the stopper (9) extends from the fitting portion (2) to the fitting portion (3) at a substantially right angle, engages with the opening edge (7) of the mounting wall (5), and is fitted by the screw (10). The tightening position of the joints (2) and (3) is looked into the opening (6) of the mounting wall (5).

The fixture (1) is formed from a rectangular elastic plate-like body as follows. A U-shaped cut (11) is formed from the fitting portion (2) to the joining portion (4), and a hole (12) is formed in the fitting portion (2). Further, two linear cuts (13) parallel to each other are made from the fitting part (3) to the connecting part (4), and the connecting part (4) is linearly cut so as to connect these cut lines (13). (14) is inserted and a screw hole (16) is formed in the strip-shaped portion (15) surrounded by the cuts (13), (14). On the part (17) of the joint part (4) on the outside of the band part (15) and the notch (13), the reinforcing ribs (18) and (19) for reinforcing the groove which are bulged outward and recessed inward are provided. Form. The part (9) surrounded by the notch (11) is used as a stopper, and this part (9) is bent inward at a right angle to the fitting part (2). The fitting part (2) is bent substantially at right angles to the connecting part (4) so that a part of the hole (20) surrounded by the cut line (11) remains in the connecting part (4). The part (17) of the connecting part (4) is bent into a semi-circular arc shape and protrudes outward from the fitting part (3). The fitting portion (3) is not parallel to the fitting portion (2) in the natural state and is inclined inward so that the fitting portions (2) and (3) are not thicker than the mounting wall (5). It fits snugly on the different opening edges (7). The tip of the part (21) surrounded by the cuts (13) and (14) is used as a fulcrum, and supports the inner surface of the tip (free end) of the band-shaped part (15) and maintains its supporting state. A bent portion (21) is formed at the tip of the strip portion (15).

The mounting tool (1) temporarily attached to the opening edge (7) of the opening (6) of the mounting wall (5) is attached to the fitting portions (2) and (3) of the mounting plate (23). Are polymerized and the screw (10) is passed through the hole (24) of the mounting plate (23), the hole (20) of the fitting part (2) and the opening (6) of the mounting wall (5), and the part (15) The fitting (1) is fixed to the opening edge (7) by screwing into the screw hole (16) and tightening both fitting parts (2) and (3). The screw hole (16) may be formed as a thread in a completely circular hole, or the circular hole may be divided into a plurality of cuts extending in the radial direction to form a screw thread without forming a thread in advance. Threads may be formed when the (10) is screwed into the hole (16).

An outlet (25) is fixed to the mounting plate (23) as an example of a wiring device, and the U-shaped insertion port (26) projects from the hole (27) to the front side of the mounting plate (23). There is.

The decorative plate (28) has a hem portion (29) bent around the decorative plate (28) and a hole (30) fitted into the insertion port (26). When the decorative plate (28) is put on the mounting plate (23), the insertion port (26) projects through the hole (28) of the decorative plate to the front side, and the hem (29) becomes the mounting plate (23). It contacts the front surface of the mounting wall (5) so as to surround the fitting part (2). The decorative plate (28) is coupled to the mounting plate (23) by inserting the screw (31) through the hole (32) of the decorative plate (28) and screwing it into the screw hole (33) of the mounting plate (23). In this connection, the screw (31) may be located outside the screw (10) (Fig. 3) or inside the screw (10) (Fig. 4). In the former case, the fixture (1) ) Hole (12) is used as a clearance hole for the screw (31), in the latter case the hole (20) of the fixture (1) is used as a clearance hole for the screw (10).

[Effect of device]

 According to the present invention, as described above, the fitting (1) is temporarily attached to the opening edge (7) of the opening (6) of the mounting wall (5) by the elasticity of the fitting portions (2) and (3). , Connect the mounting plate (19) of the wiring device to the fitting part (3) of the fitting with the screw (10), and tighten the fitting parts (2) and (3) with the screw (10). The fixture (1) is provided with a stopper (9) that is configured to be fixed and that engages with the opening edge (7) so that the tightening position of the screw (10) can be seen through the opening (6). Therefore, the fixture (1) can be easily attached to the opening edge (7) of the opening (6) of the attachment wall (5) from the front side, and thus the wiring device can be easily attached to the attachment wall (5). And it can be installed efficiently. Further, according to the present invention, since the mating portions (2) and (3) facing each other are coupled by the coupling portion (4) in such a relationship that they can be expanded substantially parallel to each other within the range where they can be restored by elasticity, This is convenient because the mating portions (2) and (3) can be elastically and easily fitted to the opening edges (7) having different thicknesses. Further, since the joint portion (4) is formed in an arc shape, the bending stress is not evenly concentrated on a part of the joint portion but is evenly distributed over the entire length of the arc portion to be strong against bending. The tightening force for temporary attachment by the fitting portions (2) and (3) can be increased. . Also, the strip-shaped portion (15) is screwed with the free end of the divided strip-shaped portion (15) of a part of the fitting portion (3) being supported by the end of the fulcrum (21) of the coupling portion (4). By tightening at (10), both fitting parts (2), (3) are tightened more strongly by the opening edge (7).
