[Problems to be solved by the device]

 In the mounting structure of the embedded luminaire of the conventional example, two hanging bolts 113 are needed for one fixture body 101 even when a plurality of fixture bodies 101 are arranged in series, which is a waste of resources. And the increase in time was unavoidable. That is, in comparison with the strength required to suspend one instrument main body 101, the suspension with two suspension bolts has an excessive strength and is wasteful. Moreover, as the number of suspension bolts 113 increases, the number of steps for tightening the suspension bolts 113 together with the nuts 115 together with the spring washers 114 also increases. Further, when tightening the nut 115, the tool body 101 had to be supported by hand, and the construction was complicated.

An object of the present invention is to provide a mounting structure for a built-in lighting fixture in which the fixture bodies can be easily connected in series and the number of suspension bolts can be saved.

[Means for Solving the Problems]

 In the mounting structure of the embedded luminaire of the present invention, notch openings are provided at the corners of the end plate of the luminaire body and the top plate. A hooking hole is provided near the opening edge of the top plate of the notch opening, and the hooking tool is attached to the hanging bolt so that it can be raised and lowered. An upward locking claw is provided at the tip of the hooking tool, and the upward locking claw is engaged with the locking hole of the top plate to mount the instrument body.

[0006]

[Action]

 The mounting structure of the embedded luminaire of the present invention has a notch opening at the corner between the end plate and the top plate of the main body of the fixture, and an upward locking claw at the tip of a hooking tool that is vertically movable on a hanging bolt. Since the upward locking pawl is engaged with the locking hole provided near the opening edge of the top plate of the cutout opening, the upward locking pawl is inserted from the opening to make the instrument body a hanging bolt. Can be easily installed.

【Example】

 A mounting structure of an embedded lighting fixture according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, in the mounting structure of the embedded lighting fixture, a cutout opening 6 is provided at a corner between the end plate 2 of the fixture body 1 and the top plate 5, and the cutout opening 6 is opened in the top plate 5. An engaging hole 7 is provided in the vicinity of the edge 5a, a hooking tool 8 is attached to the hanging bolt 3 so as to be able to move up and down, upward engaging pawls 9a and 9b are provided at the tip of the engaging tool 8, and the upward engaging pawl 8a is lifted. The device body 1 is attached by engaging with the locking holes 7 of the plate 5.

The instrument main body 1 is a long box body having an opening at the bottom, and a pair of mounting bases 12 project from both sides in the width direction, and a ballast (not shown) and the like are mounted inside. Two pairs of sockets 4 for sandwiching the fluorescent lamp 14 are provided in the lower part of both ends of the instrument body 1. The suspension bolt 3 is a threaded rod whose upper end is fixed to a beam or the like of a building. The notch opening 6 has a side surface shape in which a corner portion between the end plate 2 and the top plate 5 is inclined upward from the vicinity of the center in the height direction of the end plate 2 toward the inside of the device body 1. It is formed by cutting off the end part of. The locking hole 7 is a substantially rectangular elongated hole extending in the width direction of the instrument body 1. The hooking tool 8 has upward locking claws 9a and 9b projecting from both ends of a horizontal piece 8a, and an insertion hole 8b for a hanging bolt is drilled in the center. A guide pipe 8c having a diameter through which the suspension bolt 3 can be inserted is provided above the insertion hole 8b. The upward locking claws 9a and 9b are plate-shaped projections that can be fitted into the locking holes 7, respectively.

As shown in FIG. 2, at the time of construction, the hooking tool 8 is inserted into the hanging bolt 3 so that the longitudinal direction of the hooking tool 8 coincides with the longitudinal direction of the instrument body 1. The nut 11 is screwed into the suspension bolt 3 and the hooking tool 8 is fixed at an appropriate height position. Fix the nut 11 with a lock nut (not shown). The upward locking claw 9a is fitted into the locking hole 7 through the opening 6 of one device body 1, and then the upward locking claw 9b is fitted into the locking hole 7 through the opening 6 of another device body 1. . Using the opening 6, the power supply line 13 is inserted between the device main bodies 1 adjacent to each other.

By repeating these steps, two adjacent device main bodies 1 can be suspended by one suspension bolt 3, so that when connecting a plurality of device main bodies 1 in series, the number of suspension bolts 3 can be increased. The amount of resources can be saved by minimizing the number of times, and the number of times the nut 11 is tightened can be reduced to simplify the construction. Further, since the step of fixing the hooking tool 8 to the suspension bolt 3 and the step of fitting the upward locking claws 9a, 9b into the respective locking holes 7 can be sequentially performed, the worker can easily perform the work independently.

Although the hooks 8 are provided with the locking claws 9a and 9b at both ends in the longitudinal direction, the locking claws 9d and 9e may be additionally provided as shown in FIG.

[Effect of the device]

 The mounting structure of the embedded luminaire of the present invention has a notch opening at the corner between the end plate and the top plate of the main body of the fixture, and an upward locking claw at the tip of a hooking tool that is vertically movable on a hanging bolt. Since the upward locking pawl is engaged with the locking hole provided near the opening edge of the top plate of the cutout opening, the appliance main body is attached to the hanging bolt by inserting the upward locking pawl from the opening. It can be easily installed. Therefore, when a plurality of equipment bodies are installed in a row, two adjacent equipment bodies can be hung with a single hanging bolt, so that the number of hanging bolts can be minimized to save resources. It is also possible to simplify the construction by reducing the tightening of the nut that locks the hooking tool by screwing it to the suspension bolt. Further, since the process of fixing the hooking tool to the suspension bolt and the process of fitting the upward locking claws into the respective locking holes can be performed sequentially, the worker can easily perform the work independently.
