BACKGROUND OF THE INVENTION This invention relates to a downlight.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional downlight. Reference numeral 50 denotes an instrument body, which includes an arm 51, a top plate 52, a frame 53, and the like. An auto-lifter 55 for raising and lowering the illuminating lamp 54 is attached to an upper portion of the device main body 50. The illumination lamp 54 includes a lamp 56, a socket 57, a reflection plate 58, and the like, and is mounted on the appliance body 50. In addition,
59 is a ground terminal, 60 is a lamp terminal block, and 61 is a lifting / lowering operation terminal block.

At the time of construction, the auto-lifter 55 is inserted and fixed through an embedding hole 63 provided in a ceiling 62 with the auto-lifter 55 attached to the appliance body 50 (FIG. 7).

[0004]

However, depending on the type of downlight, as shown in FIG.
5 may protrude from the embedding hole 63 in some cases. In this case, in order to allow the auto lifter 55 to pass through the embedding hole 63, as shown in FIG.
Must be formed and tilted. Dimension A of constricted portion 64
However, there is a problem that the tool main body 50 needs to be higher than a certain length in relation to the thickness of the ceiling 62 or the like.

In addition, since the operation is performed with the auto lifter 55 attached to the instrument body 50 as described above, the auto lifter 55 is heavy, unstable, and difficult to perform. Therefore, an object of the present invention is to provide a downlight that can reduce the height of the appliance body and is easy to construct.

[0006]

The downlight according to the present invention comprises a gate-shaped appliance main body suspended by a suspension bolt hanging above an embedded hole in a ceiling, and an inner surface of both side pieces of the appliance main body. A slidable flange is formed at both ends, and a mounting bracket is provided with an auto-lifter for elevating and lowering the illumination lamp. The flange is supported.

[0007]

[Function] Only the instrument body is inserted from the embedding hole and attached to the suspension bolt. Next, the mounting bracket to which the auto lifter is mounted is inserted from the embedding hole and pushed up. At this time, the mounting bracket (auto lifter) is passed through the embedding hole by inclining the mounting bracket (auto lifter) according to the size of the embedding hole. Then, the flange of the mounting bracket is pushed up while sliding on the side piece of the appliance main body, and the locking spring projecting inward is once pushed in by the flange. Further, by pushing up the mounting bracket, the locking spring returns, and the mounting bracket can be temporarily supported by the locking spring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A downlight according to an embodiment of the present invention will be described with reference to FIGS. The downlight includes a fixture body 1, a mounting bracket 3 to which an auto lifter 2 is attached,
An illumination lamp 4 that moves up and down by an auto lifter 2 is provided.
The appliance body 1 is formed in a gate shape with an upper piece 6 and left and right side pieces 7, 7, and has a ball-shaped bolt mounting hole so as to be hung by a hanging bolt 8 hanging above an embedding hole 24 in a ceiling 23. 9 is drilled in the upper piece 6. Also, as shown in FIG.
Has a guide 10 at both ends, and is provided with a locking spring 11 made of an elastic material which can be protruded and retracted inward. Specifically, the locking spring 11 includes a mounting portion 12, an elastic deformation portion 13 inclined inwardly upward from the mounting portion 12, and a support portion having the upper end of the elastic deformation portion 13 turned substantially horizontally. 14. The support portion 14 is further bent upward, and the contact portion 15
Is formed. Also, a hole 1 is provided at a predetermined position above the side piece 7.
6, the elastic deformation portion 13 and the support portion 14 are fitted into the hole 16 from outside. The locking spring 11
The mounting portion 12 is fixed below the hole 16 by a fixing tool (not shown).
Install with. 17 are holes through which this fixing tool is inserted.
In this state, the contact portion 15 contacts the outer surface of the side piece 7 above the hole 16. Further, a fixing screw insertion hole 18 is provided above the hole 16 and above the contact portion 15. 22 is a frame,
It is fixed to the lower end of the side piece 7.

As shown in FIG. 3, the mounting bracket 3 has a plate shape with flanges 19, 19 formed at both ends, and mounting holes 20 are formed on the upper surface so that the auto lifter 2 can be mounted. The pair of flanges 19 has a fixing screw insertion hole 28 and the interval is set so that the pair of flanges 19 can slide on the inner surfaces of both side pieces 7 of the instrument body 1. The central hole 21 is provided for inserting a wire for raising and lowering the auto lifter 2 and the like.

The illumination lamp 4 includes a lamp 25, a socket 26,
It has a reflection plate 27 and the like, and is supported by the instrument body 1 via the mounting bracket 3. Next, the procedure for installing this downlight will be described. That is, only the instrument body 1 is
And the bolt mounting hole 9 is mounted on the suspension bolt 8.
Next, as shown in FIG. 4, the mounting bracket 3 to which the auto lifter 2 is mounted is inserted from the embedding hole 24 and pushed up. At this time, when the auto-lifter 2 protrudes from the embedding hole 24, the auto-lifter 2 is inclined and passed through the embedding hole 24 as shown by a two-dot chain line. Then, the flange 19 of the mounting bracket 3 is pushed up while sliding on the side piece 7 of the instrument body 1 with the guide 10 as a guide. When the flange 19 reaches the position of the locking spring 11, the flange 19 presses the elastically deforming portion 13 and once pushes this portion outward. By further pushing up the mounting bracket 3, the elastically deformable portion 13 returns, and the flange 19 is temporarily supported by the support portion 14 protruding inward. In this state, the fixing screw 29 is inserted into the fixing screw insertion holes 18 and 28 to fix the mounting bracket 3 to the instrument body 1.

As described above, the apparatus main body 1 and the auto lifter 2
Can be separately attached, so that there is no need to provide a constricted portion in the instrument body 1 and the instrument height can be reduced. Further, since the auto-lifter 2 is retrofitted in this way, the weight of the instrument body 1 is reduced when the auto-lifter 2 is attached, and the construction is facilitated. Further, in this embodiment, since the guide 10 is provided on the instrument main body 1, the flange 19 of the mounting bracket 3 is positioned, thereby facilitating the lifting operation.

[0012]

According to the downlight of the present invention, it is possible to insert only the device main body from the embedding hole and mount it on the suspension bolt, and later mount the auto lifter integrated with the mounting bracket. Therefore, there is no need to provide a constricted portion in the instrument body, and the instrument height can be reduced. In addition, when mounting the mounting bracket to the appliance body, the flange is pushed up while sliding on the side piece of the appliance body, the locking spring protruding inward is once pushed by the flange, and the mounting bracket is further pushed up. The retaining spring returns, and the flange can be temporarily supported by the retaining spring. For this reason, fixing of the mounting bracket is facilitated. In addition, since the weight of the device main body is reduced, the lifting work becomes easier.
