The screw portion 40b is provided at a position where the screw portion 40b substantially abuts, and when the screw 40 temporarily fixed to the connecting plate is tightened, the head portion 40a of the screw serves as a protrusion provided on the outer edge of the insertion hole 12 of the instrument body. As shown in FIG. 2 (B), the projection piece 14 is provided at a position substantially in contact with the projection piece 14.

A procedure for linearly mounting a lighting fixture on a ceiling surface as a mounting surface by a connecting device will be described with reference to FIGS.

The lower ends 19a of the mounting bolts 19 protruding from the ceiling surface 4, which is the surface to be mounted, are inserted into the substantially central portions of the long holes 7, 7 respectively formed at both ends of the top surface portion 6 of the appliance body. I do. Then, the nut 28 is screwed to the mounting bolt 19, and the instrument body 5 is temporarily fixed to the mounting bolt 19.

From the end of the instrument body 5 temporarily fixed to the mounting bolt 19, a connecting device 45 temporarily fixed with a screw 40 is placed on the instrument body along the longitudinal direction of the instrument body. The pair of falling pieces 38, 38 of the connecting plate 36 placed on the instrument body are placed so as to abut on the side surfaces 9, 9 of the instrument body, and the screws temporarily fixed to the connecting plate. Head 40a is in contact with the top surface 6 of the instrument body. The device main body is temporarily fixed to the mounting bolt 19 with a nut 28 by being connected to the device main body.

Then, when the connecting plate is moved right and left along the longitudinal direction of the instrument main body, the head portion 40a of the screw temporarily fixed to the connecting plate is inserted into the insertion hole 12 formed in the top surface portion 6 of the instrument main body.
When it is flush with the connecting plate, the screw 40 temporarily fixed to the connecting plate enters the insertion hole 12 of the instrument main body, and the connecting plate main body 3 of the connecting plate.
7 is placed on the top surface 6 of the instrument body,
a is located below the insertion hole 12.

When the adjacent appliance main bodies 5 and 5 are moved in the direction of approaching each other, the screw portion 40b of the screw temporarily fixed to the connecting plate 36 is inserted into the slit-shaped long hole 13 formed in the appliance main body.
The tool main body 5 stops at a predetermined connection position. Then, tighten the screw 40 and the screw head 40
The side a is fastened while being close to or in contact with a projection piece 14 as a projection provided on the edge of the gourd-shaped hole 11 on the side of the insertion hole 12, and the adjacent instrument bodies are temporarily fixed to the connecting plate 36. And connected with the screw 40.

Finally, the nut 28 temporarily screwed to the mounting bolt 19 is tightened to fix the instrument body 5 to the ceiling surface 4 which is the surface to be mounted. At this time, projecting portions 5 projecting upward and having a flat upper surface are provided at both ends of the top surface portion 6 of the instrument body.
Since 0 is provided, the tip of the screw 40 temporarily fixed to the connecting device 45 does not hit the ceiling surface 4.

After the adjacent appliance bodies 5, 5 are temporarily fixed to the mounting bolts 19 with the nuts 28, the top surfaces 6, 6 between the adjacent appliance bodies 5, 5 are straddled from the top surface side of the appliance body. It may be a mounting method.

The operation of the above embodiment will be described.

As described in the first aspect, the insertion hole 12 is slightly larger than the screw head 40a in the instrument body 5.
And the insertion hole of the gourd-shaped hole 11 provided with the slit-shaped hole 13 slightly larger than the screw portion 40b is located at the end side of the instrument main body. With this, it becomes possible to connect and fix the instrument bodies together.

Therefore, the lighting devices can be connected to each other by the connecting device without having a screw for fixing the connecting device to the lighting device main body. Therefore, it is possible to provide a connecting structure for lighting equipment with good workability.

As described in claim 2, the gourd-shaped hole 11
Is provided with a projection piece 14 as a projection projecting below the top surface portion 6 of the instrument main body, so when attaching the connecting device to the instrument main body, first, when the coupling device is attached to the instrument main body, the insertion hole is slightly larger than the screw head. The head of the screw is penetrated, and the screw is tightened at the position of the slit-like hole slightly larger than the screw portion, over the projection piece as the projection, and the coupling device and the instrument body are connected.

Therefore, since the positions of the adjacent appliance bodies connected by the coupling device are reliably positioned, the adjacent appliance bodies can be fixed at a predetermined position simply by tightening the screws.

[0040]

As described in detail above, the instrument body has a gourd-shaped hole having an insertion hole slightly larger than the head of the screw and a slit-shaped hole slightly larger than the screw portion. Since the insertion holes are arranged on the end side of the fixture main body, the fixture main bodies can be connected to each other without having a screw for fixing the connecting device to the fixture main body. Can be provided.

According to a second aspect of the present invention, since the gourd-shaped hole of the instrument body is provided with a projection on the lower surface side of the top surface of the instrument body,
By simply tightening the screws temporarily fastened to the connection fittings, the adjacent fixture main bodies can be fixed at predetermined positions, and it is possible to provide a lighting fixture connection structure with good workability.
