DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

A rail body 1 having a predetermined length and an L-shaped cross section comprises a horizontal portion 2 and a rising wall 3 perpendicular to the horizontal portion. A lateral fitting groove 4 is formed on the inside 3a of the rising wall 3 over the entire length in the longitudinal direction.
Is provided. The depth of the transverse groove 4 and D _1. The lower surface of the lateral fitting groove 4 is inclined downward from the side wall 4a to the edge 4b, and the edge 4b is formed larger than the side wall 4a. Further, a screw insertion portion 5 is provided on the upper surface 2a of the horizontal portion 2 in the vertical direction. Further, a horizontal locking hole 6 is provided in the horizontal portion 2 over the entire length in the length direction, and a locking portion 18 of a plate-shaped fixing bracket 17 is provided in the locking holes 6 at both ends of the horizontal portion 2.
Through. The fixing bracket 17 includes a hooking portion 18 and a mounting portion 1.
9, the lower surface 19a of the mounting portion 19 is formed to be bent so as to be flush with the lower surface 2b of the horizontal portion 2 in a state where the locking portion 18 is inserted into the locking hole 6. (FIG. 6). A mounting hole 20 is formed in the center of the mounting portion 19 to form the rail member 7 (FIG. 1).

A fitting edge 9 is formed on one side of the rectangular plate 8 so as to fit into the lateral fitting groove 4. Lower surface 9 of the fitting edge 9
a forms an inclined surface such that the plate thickness decreases toward the tip. Also, the other side of the fitting edge 9 is bent upward,
The thick part 10 is formed. Thick portion 1 from the upper edge of plate 8
The height L ₁ between the upper edges of the rails 0 is the same as the distance D ₂ from the upper surface of the lateral fitting groove 4 of the rail member 7 to the upper surface of the rising wall 3. Further, a stopper 11 protrudes from the upper surface 8a of the plate body 8. The distance L ₂ from the tip of the mating edge 9 to the edge of the mating edge 9 side of the stopper 11 is formed the same as the depth D ₁ of the said transverse groove. A vertical screw hole 12 is formed in the center of the plate body 8 so that
(FIG. 2). In the above, the distance L ₃ from the fitting edge 9 to the center of the screw hole 12 is equal to the bottom 4 a of the lateral fitting groove 4.
It is formed substantially the same as the distance D ₃ to the center of the screw insertion part 5.

The screw holes 12 are provided with washers 14 and 14a.
Then, the component mounting screws 15 are screwed together to form a component mounting device 16 with the rail member 7, the mounting fixture 13 and the component mounting screws 15 (FIG. 1).

Next, the use of the component mounting apparatus 16 of the present invention based on the above embodiment will be described.

A predetermined number of fittings 13 are moved horizontally so that the screw holes 12 of the fittings 13 match the positions of the mounting holes 22 of the component 21, and the fitting edges 9 of the fittings 13 are laterally fitted to the rail members 7. Groove 4
(FIG. 1). At this time, the horizontal fitting groove 4
Is easy to fit in because the edge 4b is formed large.
At this time, the stopper 11 of the attachment 13 is in contact with the edge 4b of the lateral fitting groove 4 (the inner side 3b of the rising wall 3).

Next, the component mounting screw 15 and the washer 1
4 and 14a are removed from the fixture 13, the component 21 is arranged so that the attachment hole 22 thereof matches the screw hole 12 of the fixture 13, and the washers 14, 14a and the attachment screw 15 are inserted from the attachment hole 22 side. Then, the component mounting screw 15 and the screw hole 12 of the mounting tool 13 are screwed (FIG. 5). At this time, the stopper 11 prevents the attachment 13 from rotating due to the tightening of the component attachment screw 15.

In the above description, the upper surface 10a of the thick part 10 of the fixture 13 abuts against the lower surface of the component 21, and the component mounting screw 1
5 is located in the screw insertion portion 5 of the rail member 7, the lower surface 13a of the mounting member 13 is kept horizontal, and the component 21 is also installed horizontally. In addition, since the tip of the component mounting screw 15 is located in the screw insertion portion 5, there is no possibility that the mounting member 13 will fall off the rail member. Similarly, the mounting hole 22 of the component 21 is fixed to each mounting fixture 13.

The rail member 7 on which the predetermined component 21 has been mounted is disposed at a predetermined position on the mounting surface 23, and the screws 24 and washers 25 and 25 a are inserted through the through holes 20 of the fixing bracket 17 to mount the rail member 7. It is fixed to the surface 23 (FIG. 6). Thus, the fixing of the component 21 to the predetermined position is completed. Also,
In the above, the rail member 7 was attached to the predetermined position after the component 21 was attached to the rail member 7. However, after the rail member 7 was fixed at the predetermined position, the fixture 1 was attached to the rail member 7.
3, and the component 21 can also be attached.

In the above embodiment, since the thick portion 10 of the fixture 13 is formed by bending the end of the plate 8, the portion has elasticity, and the part 21 and the fixture 13 are firmly fixed. However, the thickness of the portion of the plate 8 can be increased to form a thick portion. Further, although the plate body 8 is rectangular, a circular shape or any other shape is also possible.

In the above-described embodiment, the lower surface 9a of the fitting edge 9 of the attachment 13 is formed on the inclined surface such that the plate thickness becomes thinner toward the front end, but it may not be formed on the inclined surface. Further, without forming an inclined surface, as shown in FIG. 3, the thickness of the plate body 8 is slightly (0.
(Approximately 2 mm). The fitting edge 27 is formed to be thin, and the both ends of the fitting edge 9 are formed to have bent portions 26, 26 which are bent upward in accordance with the height of the side wall 4 a of the lateral fitting groove 4. (FIGS. 3A and 3B). Furthermore, in the above, the bent part 26 bent upward was formed, but as shown in FIG.
It is also possible to form the bent parts 26a, 26a bent downward to form the mounting fixture 27a (FIGS. 4A and 4B).

In the above embodiment, the rail member 7
The entire lower surface of the lateral fitting groove 4 is formed so as to be inclined downward from the side wall 4a to the edge portion 4b, but the side wall 4a side of the lower surface of the lateral fitting groove 4 is formed parallel to the upper surface, and the lower surface edge is formed. Only the portion 4b side may be formed to be inclined downward. Therefore, also in this case, the edge portion 4b is formed larger than the side wall 4a.

[0021]

[Effects of the Invention] Since the component mounting device is composed of a rail member having a lateral fitting groove and a fitting having a fitting edge with the lateral fitting groove, the fitting is inserted into the lateral fitting groove. Can be fitted to each other, and can be removed by pulling out the mounting tool, so that the mounting operation can be simplified and the mounting position can be easily changed. Further, since the component mounting screw is inserted into the screw insertion portion of the rail member, there is an effect that the component is firmly connected to the mounting member and the rail member.
