Abstract: A globe-mounting apparatus for explosion-proof lighting devices which provides an easier globe-mounting and dismounting operation, and which is furnished with a hinge which joins the lighting body and the globe members. Around the periphery of the opening of the lighting body is formed a circular body facing inside, to which is alternately provided a cut and a projection with a fastening bolt screwed to it. Clamps, which are shorter than the cuts furnished at the opening of the lighting body, are provided around the periphery of the globe holder which holds the globe.

Abstract: A socket-mounting apparatus for lighting devices comprising a plurality of socket-fixing clamps and a socket-fixing plate. The clamps are furnished with mounting members for socket fixing at one end and a plurality of mounting legs of different heights, each having a small screw at the other end. At each of the projections, the number of which is the same as that of the clamps provided at the socket-fixing plate's peripheral edge, is formed U-cuts cut from the direction that vertically intersects the axis direction of a lighting body. By shifting the socket-mounting location to the direction parallel to that of the lighting body's axis, the above-structured apparatus enables one to light electric bulbs of different sizes in one lighting body.

Abstract: A mounting device for a cover plate for a wall outlet box has an intermediate plate having openings at the positions corresponding to the mounting position of a convenience or a switch, and a cover plate has openings at the same positions as the position of the convenience or the like. Any desired patterns can be formed on the front surface of the cover plate. Several threaded rods are mounted on the back surface of the cover plate, the intermediate plate being provided with holes at the places corresponding to the rods, the intermediate plate being attached by screws to the mounting plate of the convenience or the like and the rods on the cover plate extend into the holes in the intermediate plate. Thus, beautiful patterns are exposed on the surface of said cover plate and the cover plate can be attached without screw heads being seen on the surface of the plate.
