【Example】

 An embodiment of this invention will be described with reference to the drawings.

A rail main body 1 having a predetermined length and an L-shaped cross section includes a horizontal portion 2 and a rising wall 3 perpendicular to the horizontal portion 2. A lateral fitting groove 4 is provided on the inner side 3a of the rising wall 3 over the entire length in the length direction. The depth of the lateral fitting groove 4 is D ₁ . The lower surface of the lateral fitting groove 4 is inclined downward from the side wall 4a toward the edge 4b, and the edge 4b is formed larger than the side wall 4a. A screw insertion portion 5 is provided in the vertical direction on the upper surface 2a of the horizontal portion 2. Further, a horizontal hooking hole 6 is provided in the horizontal portion 2 over the entire length in the lengthwise direction, and a hooking portion 18 of a plate-like fixing metal fitting 17 is fitted into the hooking holes 6 at both ends of the horizontal portion 2. Through. The above-mentioned fixing metal fitting 17 comprises a hooking portion 18 and a mounting portion 19, and a lower surface 19a of the mounting portion 19 has a lower surface 2b of the horizontal portion 2 in a state where the hooking portion 18 is inserted into the hooking hole 6. It is formed by bending so as to be flush with (FIG. 6). Further, a mounting hole 20 is bored in the central portion of the mounting portion 19 to form the rail member 7 (FIG. 1).

A fitting edge 9 that can be fitted in the lateral fitting groove 4 is formed on one side of the rectangular plate body 8. The lower surface 9a of the fitting edge 9 described above forms an inclined surface such that the plate thickness decreases toward the tip. Further, the other side of the fitting edge 9 is bent upward to form the thick portion 10. The height L ₁ between the upper edge of the plate 8 and the upper edge of the thick portion 10 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. Has been done. Further, a stopper 11 is provided on the upper surface 8a of the plate body 8 so as to project therefrom. The distance L ₂ from the tip of the fitting edge 9 to the end of the stopper 11 on the fitting edge 9 side is formed to be the same as the depth D _{1 of the} lateral fitting groove. A vertical screw hole 12 is formed in the central portion of the plate body 8 to form a fixture 13 (FIG. 2). Distance L ₃ to the center of the screw hole 12 from the mating edge 9 in the is formed substantially the same as the distance D ₃ to the center of the screw insertion part 5 from the bottom 4a of the transverse groove 4 .

The washers 14, 14 a and the component mounting screws 15 are screwed into the screw holes 12, and the rail member 7, the fixture 13 and the component mounting screws 15 constitute a component mounting device 16 (FIG. 1). ).

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

A predetermined number of fixtures 13 are horizontally moved so that the screw holes 12 of the fixture 13 are aligned with the positions of the mount holes 22 of the component 21, and the fitting edge 9 is laterally fitted to the rail member 7. It fits into the groove 4 at a fixed position (Fig. 1). At this time, the lateral fitting groove 4 is easily fitted because the edge portion 4b is formed large. At this time, the stopper 11 of the attachment 13 is in contact with the edge portion 4b of the lateral fitting groove 4 (the inner side 3b of the rising wall 3).

Next, the component mounting screw 15 and the washers 14, 14 a are removed from the fixture 13, and the component 21 is arranged such that its mounting hole 22 is aligned with the screw hole 12 of the fixture 13, and the mounting hole 22 side Then, washers 14, 14a and mounting screws 15 are inserted, and the component mounting screws 15 and the screw holes 12 of the mounting tool 13 are screwed together (FIG. 5). At this time, the stopper 11 prevents the fixture 13 from rotating by tightening the component mounting screw 15.

In the above description, the upper surface 10 a of the thick portion 10 of the fixture 13 abuts the lower surface of the component 21, and the tip 15 a of the component mounting screw 15 is located inside the screw insertion portion 5 of the rail member 7. Therefore, the lower surface 13a of the fixture 13 is kept horizontal, and the component 21 is also installed horizontally. Further, since the tip end of the component mounting screw 15 is located inside the screw insertion portion 5, the mounting tool 13 is unlikely to fall off the rail member. Similarly, the attachment holes 22 of the component 21 are fixed to the respective attachments 13.

The rail member 7 on which the predetermined component 21 has been mounted is arranged at a predetermined position on the mounting surface 23, and the screw 24 and washers 25, 25 a are inserted into the through holes 20 of the fixing bracket 17, and the rail member 7 is inserted. Is fixed to the mounting surface 23 (FIG. 6). This completes the fixing of the component 21 to the predetermined position. Further, in the above description, the rail member 7 was attached to the predetermined position after the component 21 was attached to the rail member 7, but the fixture 13 and the component 21 were attached to the rail member 7 after fixing the rail member 7 to the predetermined position. It can also be attached.

In the above-described embodiment, since the thick portion 10 of the fixture 13 is formed by bending the end of the plate body 8, the portion has elasticity and the component 21 and the fixture 13 are firmly fixed. However, it is also possible to increase the plate thickness of the portion of the plate body 8 and form the thick portion. Further, although the plate body 8 has a rectangular shape, it may have a circular shape or another shape.

Further, in the above embodiment, the lower surface 9a of the fitting edge 9 of the fixture 13 is formed as an inclined surface so that the plate thickness becomes thinner toward the tip, but it may not be formed on the inclined surface. Further, as shown in FIG. 3, the plate body 8 is formed slightly thinner (about 0.2 mm) than the side wall 4a of the lateral fitting groove 4 without forming the inclined surface, and the fitting is performed. It is also possible to form bent portions 26, 26 bent upward so that both ends of the edge 9 are aligned with the height of the side wall 4a of the lateral fitting groove 4 to form a fixture 27 (FIG. 3 (a)). (B)). Further, in the above description, the bent portion 26 that is bent upward is formed, but as shown in FIG. 4, the bent portions 26a and 26a that are bent downward can be formed to be the fixture 27a (FIG. 4 ( a) (b)).

Further, in the above embodiment, the entire lower surface of the lateral fitting groove 4 of the rail member 7 is formed so as to be inclined downward from the side wall 4 a to the edge portion 4 b. It is also possible to form the side wall 4a side in parallel with the upper surface and form only the edge 4b side of the lower surface in a downward slope. Therefore, also in this case, the edge portion 4b is formed larger than the side wall 4a.

[0021]

[Effect of the device]

 Since the component mounting device is composed of the rail member having the lateral fitting groove and the fitting having the fitting edge with the lateral fitting groove, the fitting can be fitted to each other by inserting the fitting into the lateral fitting groove. Since the attachment can be removed by pulling out the attachment, the attachment work can be simplified and the attachment position can be easily changed. Further, since the component mounting screw is inserted into the screw insertion portion of the rail member, the component has an effect of being firmly connected to the fixture and the rail member.
