Description

[0001]
[Industrial application fields]
The present invention relates to a mounting mechanism in a direct-mounted lighting fixture.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 5 and 6, a plurality of mounting screws 21 are raised on the main body 90 of the instrument, and a hole 22 through which the mounting screws 21 are inserted is provided in the cover 10. At the time of attachment, the hole 22 of the cover part 10 was covered with the attachment screw 21 of the main body part 90. Further, after the cover portion 10 is covered, the attachment screw 21 is fastened with a cap nut 23 and attached.
[0003]
[Problems to be solved by the invention]
In the above prior art, since the cap nut 23 is free, it is a factor of dropping and losing when attaching. Furthermore, since the mounting screw 21 is raised from the main body 90, the mounting screw 21 is bent during transportation, and the mounting pitch does not match, and the hole 22 of the cover unit 10 does not match.
An object of the present invention is to ensure the prevention and positioning of a mounting nut, and to facilitate the mounting of a cover portion.
[0004]
[Means for Solving the Problems]
The direct-mounted luminaire according to the present invention includes a round plate-shaped main body portion 9 on which a plurality of mounting bases 10 on which the light source 25 and the lighting circuit component 26 are placed and the cover portion 1 is screwed are placed. The cover portion 1 includes a translucent cover 2 that covers the main body portion 9, a frame 5 that sandwiches the translucent cover 2 from the front and back, and a translucent cover mounting plate 7. A cylindrical side wall 11 is provided on the outer periphery of the main body 9. A side wall 18 that circumscribes the side wall 11 of the main body 9 is provided on the outer periphery of the frame 5 of the cover 1. The cylindrical translucent cover mounting plate 7 is disposed inside the frame 5. A notch 6 for guiding the mounting base 10 of the main body 9 is provided on the side wall of the translucent cover mounting plate 7. The mounting base 10 is fitted into the notch 6.
Further, the translucent cover 2 belonging to the cover portion 1 has a flange portion around it and has a substantially hemispherical shape, and a vertical rising portion 15 is provided on the outer periphery of the flange portion. The frame 5 and the translucent cover mounting plate 7 have a cylindrical shape with a lid, a hole 3 is provided at the center of the upper lid so that the hemispherical part of the translucent cover 2 is inserted, and the cover 1 is provided around the hole 3. An attachment screw hole 13 for attaching to the main body 9 is provided. Further, the mounting screw hole 13 of the frame 5 and the mounting screw hole 13 of the translucent cover mounting plate 7 when the frame 5 and the translucent cover mounting plate 7 are overlapped with each other maintain a fixed distance, 8 is configured to be movable only in the axial direction and held vertically.
[0005]
[Action]
Since the side wall of the outer periphery of the main body is inscribed and engaged with the side wall of the cover, the position is determined when the cover is covered with the main body. Furthermore, since there is a notch for guiding the mounting base of the main body portion on the translucent cover mounting plate inside the cover portion, the cover portion can be rotated and the mounting screw on the cover side can be aligned with the position of the mounting base.
Further, since the mounting screw is movable only in the axial direction and is held vertically, it is easy to match the screw hole of the mounting base.

【Example】
The embodiment of FIGS. 1 to 4 will be described. The illustrated direct-mounting luminaire includes a round plate-shaped main body portion 9 on which a plurality of mounting bases 10 on which the light source 25 and the lighting circuit component 26 are placed and the cover portion 1 is screwed are placed. The cover portion 1 includes a translucent cover 2 that covers the main body portion 9, a frame 5 that sandwiches the translucent cover 2 from the front and back, and a translucent cover mounting plate 7.
A cylindrical side wall 11 is provided on the outer periphery of the main body 9. A side wall 18 that circumscribes the side wall 11 of the main body 9 is provided on the outer periphery of the frame 5 of the cover 1. The cylindrical translucent cover mounting plate 7 is disposed inside the frame 5. A notch 6 for guiding the mounting base 10 of the main body 9 is provided on the side wall of the translucent cover mounting plate 7. The mounting base 10 is fitted into the notch 6.
The direct-attached lighting fixture of FIGS. 1 to 4 will be further described. The translucent cover 2 belonging to the cover portion 1 has a collar portion around it and has a substantially hemispherical shape. A vertical rising portion 15 is provided on the outer periphery of the flange portion. The frame 5 and the translucent cover mounting plate 7 have a cylindrical shape with a lid, and a hole 3 is provided at the center of the upper lid so that the hemispherical portion of the translucent cover 2 is inserted. An attachment screw hole 13 for attaching the cover portion 1 to the main body portion 9 is provided around the hole 3. The mounting screw hole 13 of the frame 5 and the mounting screw hole 13 of the translucent cover mounting plate 7 when the frame 5 and the translucent cover mounting plate 7 are overlapped maintain a certain distance, and the mounting screw 8 Is configured to move only in the axial direction and be held vertically.
The frame 5 has a hole 3 through which the hemispherical portion of the translucent cover 2 can be inserted, and a mounting screw hole 4 around the hole 3. The translucent cover mounting plate 7 is substantially similar to the frame 5 and is provided with a notch 6 having a width of W on the outer peripheral side wall. The mounting base 10 has a width w smaller than the width W of the notch 6 so as to fit into the notch 6 of the translucent cover mounting plate 7. The cover portion 1 is attached by covering the cover portion 1 with the main body portion 9, inscribing the side wall 11 of the main body portion 9 with the side wall 18 of the frame 5, and aligning the mounting screw 8 and the mounting base 10. , The mounting base 10 is fitted into the notch 6, and the position is determined. When there is no position, the translucent cover mounting plate 7 hits the upper part of the mounting base 10 and feels floating, so it is easy to check whether the position is present.
The structure of the cover part 1 is demonstrated with FIG. 2 and FIG. The translucent cover 2 is inserted into the hole 3 of the frame 5 and is clamped and fixed by the translucent cover mounting plate 7. The translucent cover mounting plate 7 is fastened to the mounting base 17 of the frame 5 with a set screw 12 and placed on the inner surface of the frame 5. The mounting screw 8 is inserted into the mounting screw hole 4 of the frame 5 and the mounting screw hole 13 of the translucent cover mounting plate 7, and a rubber packing 14 is attached to the mounting screw 8 to prevent the mounting screw 8 from coming off.
FIG. 3 shows a cross section of a portion where the translucent cover mounting plate 7 is fixed to the frame 5. In order to increase the strength of the translucent cover 2, a vertical rising portion 15 is provided in the collar portion, and the vertical rising portion 15 is sandwiched and fixed between the frame 5 and the translucent cover mounting base 7. The height H between the frame 5 and the translucent cover mounting base 7 is uniform over the entire circumference. Therefore, as shown in FIG. 4, the mounting screw 8 can be held so as to be movable only in the axial direction. For this reason, when the mounting screw 8 is fastened to the mounting base 10 of the main body 9, the position is easily aligned with the screw hole 16 of the mounting base 10.
[0007]
【The invention's effect】
According to the present invention, attachment can be performed without dropping the attachment screw, and alignment can be easily performed. Further, the mounting screw can be moved only in the axial direction, and the mounting screw can be fitted to the screw hole of the mounting base without being shaken. Further, since such a mechanism can be performed with a small number of parts, the number of assembling steps can be reduced.
