TECHNICAL BACKGROUND OF THE INVENTION
This invention relates to a mounting structure for wiring devices and having a decorative plate at outer front face.
The wiring-device mounting structure of the type referred to is effectively utilized in fixedly mounting such electric wiring devices as a wall switch, outlet, earthing terminal, antenna terminal, dimmer and the like to such a constructional member as a building wall.
DISCLOSUR~ OF PRIOR ART
Hitherto, there have been proposed various sorts of mounting structures for the wiring devices, and typical one of them is disclosed in U.S. Patent No. 4,163,882 to F.M. Baslow, in which a mounting frame made integral with a wiring device is fastened with screws to a box embedded in a building wall and a decorative plate is screwed to the mounting frame. However, this structure has had such a problem that the screws for securing the decorative plate to the mounting frame have to be left as exposed on front face of the decorative plate to render its appearance unfavorable.
Disclosed in U.S. Patent No. 3,197,549 to ~.J. Good is a mounting structure in which the wiring device is integrally provided with a laying plate to be fitted to a building wall, a gripping melnber formed to have thin fingers at front wall is ittingly mounted in cach oE

bores made at corners of the laying plate, and a decorati~e plate is provided on its inner wall with tear-drop shaped mating projections which can be gripped by the fingers of the ~ripping members, so as to have the decorative plate mounted to the laying plate. According to this arrangement, the mounting of the decorative plate to the laying plate achieved with the gripping members and mating projections requires no screw which is exposed on the front face of the decorative plate, and the mounting structure can be of an excellent appearance.
In this mounting structure of Good, however, there remain still such problems that, first, the inner surface of the decorative plate is spaced from the laying plate by a relatively large distance which renders the te~r-drop shaped projections to be longer to cause their neck portions to become much thinner than the tear-drop portions thereof enough for rendering the projections to be less strong at the neck portions to be easily broken;
second, the fingers o~ the gripping members made thin enough to be elastic are sùbjected to a downward stress when the projections are urged into the gripping members and also to an upward stress once the projections are held within tlle gripping melllbers due to the tear-drop shape of the projections, so that the fingers become easily breakable; and third, the gripping members which are provided separately from the laying plate wllich in turn is formed to have boros or intcgrally moulltillg the gripping mernbers onto the l~ying plate are rendering the ~;~7183~

TECHNICAL FIELD OF THE INVENTION
A primary object of the present invention is, therefore, to provide a wiring device mounting structure which does not expose to the exterior required coupling means between decorative and laying plates to provide a favourable appearance, and is still effective enough to maintain part on the decorative plate side of the coupling means to be highly durable.
According to the present invention, the above object is attained by a wiring device ~ounting structure`which comprises a mounting frame on which a wiring device is mounted for installation in a construction member, a laying plate interposed between the mounting frame and a mounting surface of the construction member, and a decorative plate having an opening therein for exposing a portion of the wiring device to the exterior. 'rhe mounting frame is disposed between the laying plate and the decorative plate. The decorative plate covers a front face of the laying plate. The laying plate includes a support surface means facing an inner surface of the decorative plate. The mounting frame is supported on the support surface means. The laying plate includes raised portions disposed inside of an outer periphery of the laying plate and extends toward the inner surface of the decorative plate. The raised portions form immovably rigid locking surfaces facing away from the air surface and cam surfaces disposed in front of respective locking surfaces. The distance between the locking surfaces and the inner surface is less than the distance between the support surface means and the inner surface. A plurality of short locking projections is disposed on the inner surface and extends toward the laying plate. Free ends of the projections form hooks and are engageable with the cam surface to be flexed side-wardly thereby until the hooks pass rearwardly beyond the locking surfaces and rebound to become superimposed behind the locking surfaces in manner requiring that the hooks be displaced sidewardly by a tool in order to remove the decorative plate forwardly from the laying plate. An outer edge of the laying plate includes arecess arrang~d to receive a tool inserted between ~ ~ 71 ~3~
the outer edge and an outer edge of the decorative plate for flexing the decorative plate in a manner displacing adjacently disposed ones of the hooks sidewardly and out of superimposed relationship with the locking surfaces.

According to the above arrangement, the raised ' portions of the laying plate which are for~ing part of the coupling means are so raised as to lessen the zone distance between the decorative and laying plates in their coupling zone, so that the length of the engaging projections of the decorative plate can be minimized to prevent thern from becoming low in the mechanical strength.
' Yet, the locking means for these engaging projections causes their hooked ends only to be locked to the means w.ithout being subjected to any excessive stress.
. Accordingly, the coupling means can be ,effecti.vely prevented rom being readily broken and the mounting ~tructure can be improved in the durability.

2~b and 28c are provided in four corners of the mounting frame 12.
The laying plate 13 is formed substantially in a rectangular frame shape rounded at four corners and has a large o~ening 31 in the center, on the peripheral side edges of which the mounting frame 12 can be seated. In the illustratedembodiment, the laying plate 13 is formed to have at four corners mounds 32, 32a, 32b and 32c which are bulgingly raised to be closer to the inner face of the decorative plate 14 and are aligned at their inner edges with edges of the notches 28 to 28c of the mounting frame 12. The mounds 32 to 32c are provided respectively with each of engaging ~lots 33, 33a, 33b and 33c which are penetrating through the mounds in their thickness direction, while engaging steps 34, 34a, 34b and 34c facing downward are provided on portions of peripi~eral walls of the engaging slots. Tl)e laying plate 13 also l~as opposing side parts 35 and 35a which correspond to the side parts 22 and 22a of the mounting plate 12, and ~:7~&3;~
notches 36 and 36a are provided in the side par-ts 35 and 35a in alignment with the slots 26 and 26a of the mounting plate 12, while.positioning pins 3~ and 37a are erected on the side .parts 35 and 35a for engagement in the round holes 27 and 27a of the mounting plate 12 when the latter is placed on the laying plate 13. Further, the other side parts 3~ and 38a of the laying plate 13 which. are corresponding to the side parts 22 and 22a of the mounting plate 12 are configurated to carry the side parts 22 and 22a respectively between the mounds 32 and 32a and 32b and 32c.
: The decorative plate 14 which is formed in a thin box shape opened on the side of the laying plate 13 is provided in its center with an opening 41 through which a major front face part of the wiring device 11 mounted in the mounting frame 12 is externally exposed. The decorative plate 14 is also provided on the inner face with pro~ections 42, 42a, 42b and 42c which are hooked at ; ~ their downward extended ends 43, for insertion into the engaging slots 33 to 33c in the mounds 32 to 32c of the laying plate 13. When the decorative plate 14 is coupled to the laying plate 13, as seen best in FIG. 2, the hooked ends 43 of the projections 42 to 42c of the plate 14 are brought into locking engagement with the steps 34 in the ;~ 25 slots 33 to 33c of the mounds 32 to 32c of the plate 13, with the projections 42 to 42c once bent slightly outward to the peripheral side of the decorative plate 14 when passed through relatively narrow inlet.s 44 of the ,, .

respective slots 33 to 33c until they pass completely , through the inlets 44. When the decorative plate 14 is thus coupled to the laying plate 13, the distance between, the inner surface of the decorative pl~te li and an upper S surface 45 of the mounds 32 to 32c of the layiny plate i3 is minimized in coupling zones between the both plates 13 and 14, and correspondingly the distance between the inner ' surface of the decorative plate 14 and the locking steps ;~ 34 ,to 34c of the laying plate 13 is minimized.
Consequently, the engaging projections 42 to 42c extruded from the decorative plate 14 can be minimized in the length to maintain their sufficient strength. One side wall of the respective inlets 44 of the engaging slots 33 to 33c is formed to ,be preferably curved at the upper corner edge 46 so that the hooked ends 43 of the engaging projections 42 to 42c can be smoothly guided into the ' inlets 44. The locking engagement between-the hooked ends ,,'~" ~3 of the projections 42 to 42c and the steps 34 of the ~" ' , .
