BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direct lighting device.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional example. That is, this directly-mounted lighting device has a peripheral side plate composed of a pair of side plates 70 and an end plate 71 and a top plate 72, and a groove 73 in a direction parallel to the side plate 70 is formed in the top plate 72, and the fixture directly-mounted surface An apparatus main body 78 in which a hole 76 for passing a tightening bolt 75 protruding from 74 is formed on the bottom surface 77 of the groove 73, and a louver attached inside an opening 79 facing the top plate 72 of the apparatus main body 78 as an example. And an orientation control member 80 that performs the control.

In this directly mounted lighting fixture, the fixture body 78 is approached to the fixture mounting surface 74, the hole 76 is passed through a fastening bolt 75, and the fixture 81 is tightened with a nut 81.
4 and an orientation control member 8 in an opening 79.
0 is attached.

[0004]

However, when the fastening bolt 75 is tightened with the nut 81, the edge of the groove 73 of the top plate 72 comes into contact with the device mounting surface 74 when the tightening bolt 75 is tightened. Since the bottom surface 77 of the 73 rises, the side plate 7
0 is bent inward as indicated by the imaginary line. As a result, the width of the opening 79 is reduced, and the orientation control member 8 such as a louver is formed.
There is a disadvantage that 0 cannot be inserted.

On the other hand, in order to prevent deformation of the bottom surface 77 of the groove 73, a reinforcing plate (not shown) is added in the vicinity of the hole 76 through which the tightening bolt 75 is passed. In addition, there is a drawback that the reinforcing plate is obstructed when tightening the nut and is difficult to perform. Further, there is a possibility that the mounting work may be performed without forgetting the mounting of the reinforcing plate. Therefore, an object of the present invention is to provide a directly-mounted lighting fixture capable of suppressing the bending of the side plate without requiring a reinforcing plate.

[0006]

According to the present invention, there is provided a direct lighting apparatus having a pair of side plates and an end plate, a peripheral side plate and a top plate, wherein a groove is formed in the top plate in a direction parallel to the side plate. A tool body having a hole formed in the bottom surface of the groove, through which a tightening bolt protruding from the direct mounting surface is formed, and an orientation control member attached inside an opening of the tool body facing the top plate; By tightening the tightening bolts with nuts, the tips come into contact with each other, and a convex portion that regulates the amount of inward bending of the side plate to the extent that the orientation control member can be mounted is provided on the bottom surface of the groove. Things.

[0007]

According to the structure of the present invention, the instrument body is attached to the instrument direct mounting surface by passing the hole of the instrument main body through the fastening bolt on the instrument direct mounting surface and tightening with the nut. In this case, before or almost at the same time as the edge of the groove on the top plate comes into contact with the device mounting surface, the tip of the convex portion contacts the device mounting surface, so hold down the bottom surface of the groove by tightening the tightening bolts. As a result, the amount of deflection of the side plate toward the opening can be suppressed to such an extent that the orientation control member can be mounted inside the opening. In addition, since a reinforcing plate is not required, the weight of the instrument body is reduced, and a work space for tightening the nut can be secured, so that the work is facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. That is, this directly-mounted lighting fixture is the fixture body 1
And an orientation control member 2. The instrument body 1 has a peripheral side plate including a pair of side plates 3 and an end plate 4 and a top plate 5.
Is formed in the top plate 5 in a direction parallel to the
The hole 9 through which the fastening bolt 8 protrudes from the bottom surface of the groove 6 is formed.
Is formed. Reference numeral 13 denotes a folded portion formed on the side of the side plate 3 on the opening 12 side.

A projection 11 is protruded from the bottom surface 10 of the groove 6, and a tightening bolt 8 is tightened with a nut 10 so that the tip of the projection 11 comes into contact with the instrument mounting surface 7, and the orientation control member 2 is moved. The amount of inward bending of the side plate 3 is restricted to such an extent that it can be mounted. The degree to which the orientation control member 2 can be mounted may be any degree as long as it can be substantially inserted. In the embodiment, the height b of the projection 11 is higher than the depth a of the groove 6, and b> a. The convex portion 11 has a bottom surface 10 at the center of the groove 6 in the longitudinal direction.
Are formed in the width direction.

The orientation control member 2 is mounted inside an opening 12 facing the top plate 5 of the instrument body 1. The orientation control member 2 of the embodiment is a louver, and is attached to the edge of the opening 12 by a known attachment means. According to this embodiment, the tool main body 1 is attached to the tool direct mounting surface 7 by passing the fastening bolt 8 of the tool direct mounting surface 7 through the hole 9 of the tool main body 1 and tightening with the nut 10. In this case, the top plate 7
Before the edge of the groove 6 comes into contact with the device mounting surface 7, the protrusion 11
Of the side plate 3 is held down by the tightening of the tightening bolts 8 so that the bottom surface 14 of the groove 6 is restrained from floating. It is possible to reduce the size to such a degree that it can be mounted inside the opening 12. In addition, since a reinforcing plate is not required, the weight of the instrument body 1 is reduced, and a work space for tightening the nut 10 can be secured, thereby facilitating the work.

Further, as in the embodiment, if the height b of the convex portion 11 is higher than the depth a of the groove 6 and b> a, the inward bending of the side plate 3 due to the tightening of the tightening bolt 8 is reduced. Since the bending of the side plate 3 due to the outward bending of the side plate 3 is prevented, the bending of the side plate 3 can be eliminated, and the bending of the side plate 3 can be more reliably prevented. In the above embodiment, the height b of the convex portion 11 is higher than the depth a of the groove 6 and b> a. However, even if they are substantially equal, the floating of the bottom surface 14 can be prevented.

[0012]

According to the lighting device of the present invention, before the edge of the groove of the top plate comes into contact with the device mounting surface or almost at the same time, the tip of the projection comes into contact with the device mounting surface. As a result that the bottom surface of the groove is restrained from floating by tightening the bolt, the amount of deflection of the side plate toward the opening can be suppressed to such an extent that the orientation control member can be mounted inside the opening. In addition, since a reinforcing plate is not required, there is an effect that the weight of the instrument body is reduced, and a working space for tightening the nut can be secured, thereby facilitating the work.
