  Hereinafter, a lighting fixture according to a first embodiment of the present invention and a lighting fixture apparatus including the fixture will be described with reference to FIGS. 1 to 5. FIG.1 and FIG.2 (a) (b) shows the state at the time of the structure of the lighting fixture attachment (henceforth a fixture) 1 concerning this embodiment, arrangement | positioning, and attachment. The fixture 1 is attached to a square hook ceiling body (hereinafter abbreviated as a sealing body) 2 installed on the ceiling C from below. The sealing body 2 has a substantially rectangular parallelepiped shape, for example.

  The fixture 1 includes an adapter main body 11 that is fitted to the outer peripheral portion 2 a of the sealing body 2 and is fixed to the ceiling C. The adapter body 11 has a fitting hole 111 into which the sealing body 2 is fitted, a locking step 112 provided on the outer peripheral surface 11a, and a screw hole 113 into which the screw 5 is inserted from below. The adapter main body 11 is made of, for example, resin, and the shape in plan view is circular, for example, and the upper surface and the lower surface are flat. The screw 5 is made of a wood screw, for example. In addition, the planar view shape of the adapter main body 11 is not limited to the above.

  The fitting hole 111 is provided so as to penetrate from the upper surface to the lower surface of the adapter main body 11. The shape of the fitting hole 111 corresponds to the shape of the outer peripheral portion 2 a of the sealing body 2, and the planar view shape of the fitting hole 111 is the same shape as the planar view shape of the sealing body 2.

  The locking step 112 is provided, for example, at the lowermost part of the outer peripheral surface 11a over the entire periphery, and has a tapered surface on the lower surface side. A locking portion (not shown) of the lighting fixture is locked to the locking step portion 112. For this reason, when attaching a lighting fixture to the ceiling C, the lighting fixture can be fixed to the ceiling C by the two members of the sealing body 2 and the fixture 1. Therefore, when a lighting fixture is heavy, it can prevent that a lighting fixture remove | deviates from the ceiling C with the sealing body 2 or the ceiling body 2, and falls. In addition, a heavy load and heat resistant hook sealing body stipulated in the Japan Wiring Equipment Manufacturers Association Standard JWDS0015, which is compatible with heavy lighting fixtures, is known. Sealing body is popular. For this reason, according to the fixture 1 according to the present embodiment, it is possible to remove the square hook sealing body and perform the electrical wiring again without installing the high-load / heat-resistant hook sealing body. Since it only needs to be fitted on and fixed to the ceiling C, it is possible to simplify the mounting operation.

  For example, two screw holes 113 are provided penetrating from the upper surface to the lower surface of the adapter main body 11. The upper and lower parts have different diameters, and the upper part has a smaller diameter than that of the lower part. The screw 5 inserted from below is stopped at a position where the diameter of the screw hole 113 is changed. The adapter body 11 is fixed to the ceiling C by this screw 5. The number of screw holes 113 is not limited to the above.

  The height of the adapter body 11 is substantially the same as the height of the sealing body 2. Therefore, when the sealing body 2 installed on the ceiling C is fitted into the fitting hole 111 of the adapter main body 11 and the upper surface of the adapter main body 11 comes into contact with the ceiling C, the lower surface of the sealing body 2 and the lower surface of the adapter main body 11 And form a substantially flat surface. With such a configuration, when the lighting fixture is attached to the fixture 1, the distance between the ceiling C and the lighting fixture is shortened. For this reason, the room can be made open.

  As described above, when the fixture 1 is attached to the sealing body 2, operations such as removal of the sealing body 2 and re-connection of electrical wiring are unnecessary. The fitting 1 can be attached to the ceiling body 2 and fixed to the ceiling C simply by fitting the sealing body 2 into the fitting hole 111 of the fitting 1 and tightening the screw 5. For this reason, simplification of the mounting work can be measured. Accordingly, the sealing body 2 can be provided with the locking step portion with a simple operation. Furthermore, since the structure of the fixture 1 is simple, the manufacturing process can be simplified and the cost can be reduced.

  FIG. 3 shows a state where the locking portion 31 (locking means) of the lighting fixture is locked to the adapter main body 11. The locking portion 31 of the lighting fixture includes a holder 311, a locking piece 312 housed in the holder 311, and a coil spring 313 that biases the locking piece 312. The holder 311 has an annular shape having a fitting opening 311a having a size substantially the same as that of the adapter main body 11 in plan view. The holder 311 is provided with, for example, two openings 311b on the inner side, and a locking claw 312a at the tip of the locking piece 312 is urged from each opening 311b by a coil spring 313. The locking claw 312 a has a tapered surface on the upper surface side, and can be easily locked to the sealing body 2.

  When the holder 311 of the lighting fixture is pushed up so that the adapter main body 11 is fitted into the fitting opening 311a, the tapered surface of the locking claw 312a comes into contact with the tapered surface of the locking step 112 of the fixture 1. Due to this contact, the locking claw 312a slides on the locking step 112 of the fixture 1 and moves outward against the force of the coil spring 313 trying to extend. When the holder 311 is continuously pushed up, the latching claw 312a gets over the latching step 112 of the fixture 1 and moves above the latching step 112 of the adapter main body 11 by the elasticity of the coil spring 313. 112 is locked. As described above, since the locking step 112 of the fixture 1 is provided over the entire circumference of the outer peripheral surface 11a, the lighting fixture is prevented from falling due to the locking position of the locking claw 312a being shifted. it can.

The thin plate 12 is provided with a screw hole 121, and the screw 6 is inserted into the screw hole 121 from above. The thin plate 12 is fixed to the upper surface of the adapter body 11 by the screw 6. Further, the thin plate 12 is substantially divided into two at a position corresponding to a boundary where the adapter main body 11 is substantially divided into two, and is fixed to the upper surface of the adapter main body 11 divided into substantially two (plate-like members). Each of the divided thin plates 12 is provided with one screw hole 121, for example. The fixing of the thin plate 12 to the adapter main body 11 is not limited to the screw 6 and may be performed by a rivet or the like.

  Further, when the sealing body 2 is fixed to the ceiling C, the thin plate 12 is located between the ceiling C and the ceiling body 2 and escapes to release a screw 7 (fixing tool) for fixing the sealing body 2 to the ceiling C. A hole 122 is provided. This sealing body 2 has, for example, two screw holes 21 provided so as to penetrate from the upper surface to the lower surface. A screw 7 is inserted into each of these screw holes 21 from below. The screw 7 protrudes upward from the sealing body 2 and fixes the sealing body 2 to the ceiling C. In order to allow the protruding screw 7 to escape, the thin plate 12 is provided with the escape hole 122. The escape hole 122 is formed by adding two semicircular or U-shaped notches 122a provided in each of the thin plates 12 divided into approximately two. The position of the escape hole 122 as described above is located above the screw hole 21 of the sealing body 2, and the number thereof is the same as that of the screw hole 21 of the sealing body 2.

  FIG. 8 shows how the fixture 1 is attached to the sealing body 2. First, the screw 7 of the sealing body 2 fixed to the ceiling C is loosened, and a gap is provided between the ceiling body 2 and the ceiling C. A portion of the thin plate 12 that is substantially divided into two is inserted into the gap from the left and right in the drawing. They are inserted until they abut. When the thin plate 12 divided into approximately two parts comes into contact with each other, the respective cutout portions 122 a form escape holes 122. The screw 7 of the sealing body 2 is tightened again. When the screw 7 is tightened, the screw 7 passes through the escape hole 122 and therefore does not hit the thin plate 12. In this way, the fixture 1 is mounted on the ceiling C.
