Abstract

PURPOSE:To enhance fixing performance and achieve a stable fixed state by fixing a socket fixing fitting to a base with one fixing screw. CONSTITUTION:A socket fixing fitting 11 is bent into a substantially L-shaped form. The width of a fixed portion 12 is set at 'a', and the thickness of the fitting 11 is set at 'b'. One side of an opening 10 is set at 'a'' which is slightly larger than the width 'a', and the other side thereof is set at 'b'' which is twice or a little larger than the thickness 'b'. The fixed portion 12 is inserted into the opening 10, and a fixing screw 16 is inserted through fixing holes 14 and 15 facing to each other so that the fitting 11 is fixed into a base 7. Prior to bending a side plate 9, the opening 10 is stamped, and then it is bent at the substantial center thereof. Therefore, a secure fixed state cam be easily achieved.

Description

[Detailed description of the invention] Industrial applications TECHNICAL FIELD The present invention relates to lighting equipment.

2. Description of the Related Art Conventionally, the structure shown in FIG. 3 has been common as a mounting structure for a socket mounting bracket for holding a socket in a lighting device. That is, a base body 1 bent into a box shape is provided, and socket mounting fittings 3 are fixed to both longitudinal ends of a substrate portion 2 of the base body 1 with two fixing screws 4.

The socket mounting fitting 3 includes a fixing part 5 fixed to the substrate part 2 and a holding part 6 for holding a socket (not shown), and is formed in an oval shape.

Problems to be Solved by the Invention First, the socket mounting bracket 3 is installed using two fixing screws 4, which is time-consuming. In addition, two fixing holes for passing the fixing screws 4 must be formed in each of the board part 2 and the fixing part 5, and it is expensive to process these holes so that the opposing fixing types will not be misaligned. Precision is required. Furthermore, when the socket mounting bracket 3 is attached, the step formed between the fixing part 5 and the board part 2 is visible from the outside, detracting from the appearance.

Means for Solving the Problems: A base body having a base plate portion and side plate portions bent at opposite ends of the base plate portion, and an abbreviated shape having a fixing portion and a holding portion for holding a socket. A socket mounting bracket is provided, and a rectangular opening having one side having a dimension substantially equal to the width of the fixing part and the other side having a dimension approximately twice the thickness of the socket mounting bracket is provided in the side plate part. one fixing hole formed in the fixing part and one fixing hole formed in the end of the base plate part facing each other while inserting the fixing part into the opening; Then, the fixing screws were inserted into these fixing holes.

Insert the fixing part of the working socket mounting bracket into the opening, and make the fixing hole formed in the fixing part and the fixing hole formed in the board part face each other,
The socket mounting bracket is attached to the base by inserting fixing screws into these fixing holes.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 and 2. First, a base body 7 of the lighting device is provided, which is bent into a box shape, and this base body 7 includes a base plate part 8 and a base body 7 which is bent into a box shape.
It has side plate portions 9 formed by bending at both ends in the longitudinal direction facing each other. The side plate portion 9 has a folding line 11A.
It is bent along H, and this folding line LI A
A rectangular opening 10 is formed approximately at the center of Tl.

Next, a pair of socket fittings 11 for holding sockets (not shown) are provided. This socket mounting bracket 11 has a fixing part 12 and a holding part 13 that holds the socket, and is bent into an abbreviated shape. The dimensions are set to IlbI+. Note that the dimension IIaIII of one side of the opening 1o is set slightly larger than the width dimension I+ of the fixing part 12, and the dimension 11b/II of the other side of the opening 10 is the thickness dimension IIb of the socket mounting bracket 11. The fixing hole 14 is set in the fixing part 12.
One mounting hole 15 is formed at both ends of the base plate portion 8, and one mounting hole 15 is formed opposite to the mounting hole 14. Then, after the fixing part 12 is inserted into the opening 10 and the mounting holes 14 and 15 are made to face each other, the fixing screws 16 are inserted into these mounting holes 14 and 15, and the socket mounting bracket 11 is attached to the base body 7. is being carried out.

In such a configuration, the opening 10 is punched out before the side plate 9 is bent, and when the side plate 9 is bent, the opening 10 is also bent from approximately the center. Base body 7
To attach the socket mounting bracket 11 to the socket mounting bracket 11, insert the fixing part 12 of the socket mounting bracket 11 into the opening 10, and then insert the socket mounting bracket 11 into the mounting hole 14.
After aligning 15 with each other, these mounting holes 14.15
This is done by inserting the fixing screw 16 through.

Here, since the socket mounting bracket 11 is fixed with a single fixing screw 16, the fixing position can be easily aligned, and the number of screw tightening steps is halved compared to the conventional example. 11 installation work can be easily done without any hassle. In addition, when the socket mounting bracket 11 is attached, both sides of the socket mounting bracket 11 in the width direction contact the edges of the opening 10, so a secure mounting condition can be achieved even though the socket mounting bracket 11 is mounted using the negative fixing screws 16. It will be done. Furthermore, since the fixing part 12 is inserted inside the base plate part 8, no step appears on the outer periphery of the base body 7, and moreover, the opening 1
No gap is created between o and the socket mounting bracket 11, and the appearance is improved.

Effects of the Invention The present invention can improve the ease of mounting by attaching the socket mounting bracket to the base body with a single fixing screw as described above, and in addition, the socket mounting bracket has an opening on the side. Because the socket contacts the edge of the base, a stable mounting condition can be obtained, and since the fixed part of the socket mounting bracket fits inside the base, no step appears on the outer periphery of the base.
It has effects such as being able to improve the appearance 6
