【Example】
An embodiment of the present invention will be described below with reference to FIGS.
In FIG. 4, the sun visor body 1 is rotatably fitted to a horizontal shaft portion 3 of an L-shaped support shaft 2.
As shown in FIG. 1, the support shaft 2 is supported on a mounting bracket 11 at a longitudinal axis portion 4 thereof, and is mounted on a ceiling panel 5 of a vehicle compartment. The ceiling panel 5 is made of a steel plate, and an interior member 6 is provided on the indoor surface.
[0007]
As shown in FIGS. 1 and 3, the mounting bracket 11 is made of a synthetic resin, and has a flange 12 facing the room side of the ceiling panel 5 with the interior member 6 interposed therebetween. The interior panel 6 and the boss 13 inserted into the through holes 7 and 8 of the ceiling panel 5 are integrally provided.
The boss portion 13 is formed in a rectangular cylindrical shape having a bearing hole 14 into which the longitudinal axis portion 4 of the support shaft 2 is rotatably fitted at the center thereof. A locking claw 15 that engages with a locking groove 4a formed on the outer peripheral surface of the distal end portion of the longitudinal axis portion 4 to prevent the removal is formed. The split groove 16 is formed radially so as to be elastically expanded. In other words, when the longitudinal axis portion 4 of the support shaft 2 is pushed in from the lower end opening of the bearing hole 14 of the boss portion 13, the upper end portion of the boss portion 13 is once elastically expanded, and subsequently, The locking claw 15 is elastically engaged with the locking groove 4a by pushing the locking groove 4a of the shaft portion 4 to the position where the locking claw 15 of the boss portion 13 is reached. The support shaft 2 is fitted into the boss 13.
[0008]
In addition, a removal hole 30 through which a removal tool is inserted is formed in the flange 12 of the mounting bracket 11 as necessary.
[0009]
On both sides of the outer surface of the boss 13, a pair of engaging portions 17 having a mountain-shaped cross section is protruded, while on the back side of the ceiling panel 5, the mounting bracket 11 is attached to the boss 13. The clip 21 to be engaged is fixed.
As shown in FIGS. 1 and 2, the clip 21 is made of a rectangular spring plate, and is fixed to the back surface of the ceiling panel 5 with rivets 9 at mounting holes 22 penetrating near both ends in the longitudinal direction. ing. At the center portion of the clip 22, a square hole-shaped notch 23 is formed at a position corresponding to the through hole 7 of the ceiling panel 5, and at both sides of the notch 23, a through hole of the ceiling panel 5 is formed. A pair of elastic locking pieces 24 projecting toward the center of 7 are cut and raised.
Further, the pair of elastic locking pieces 24 of the clip 21 are provided with a guide portion 25 for pushing and guiding the pair of engaging portions 17 of the boss portion 13 and when the boss portion 13 is pushed to a required position. And a locking portion 26 which elastically presses and engages the lower surface of the engaging portion 17 of the boss portion 13 to draw the boss portion 13 into the depth side of the ceiling panel 5. It is bent.
[0010]
This embodiment is configured as described above. Therefore, when attaching the mounting bracket 11 to the ceiling panel 5, the clip 21 is fixed to the rear surface side of the ceiling panel 5 with the rivet 9 in advance, while the brace portion 13 of the mounting bracket 11 is The shaft 2 is fitted at its longitudinal part 4.
Here, the boss portion 13 of the mounting bracket 11 is inserted into the through holes 7 and 8 of the interior member 6 and the ceiling panel 5 and pushed between the pair of elastic locking pieces 24, so that the boss portion 13 While the two engaging portions 17 are guided in contact with the guide portions 25 of the two elastic locking pieces 24, the two elastic locking pieces 24 are elastically expanded.
[0011]
Subsequently, the boss portion 13 is moved to a predetermined position where the flange 12 abuts on the lower surface of the interior member 6 of the ceiling panel 5 and the two engaging portions 17 of the boss portion 13 pass through the guide portions 25 of the two elastic locking pieces 24. Is pushed in, and the elastic portions of the pair of elastic locking pieces 24 resiliently expand, so that the locking portions 26 of the elastic locking pieces 24 lower the lower surfaces of both the engaging portions 17 of the boss portion 13. The mounting bracket 11 is locked against the ceiling panel 5 by being pressed against and engaged with the ceiling panel 5.
In this manner, the mounting bracket 11 is attached to the ceiling panel 5 by a very simple operation of pressing the boss 13 of the mounting bracket 11 between the pair of elastic locking pieces 24 of the clip 21 fixed to the ceiling panel 5. Can be quickly and reliably mounted.
[0012]
Further, as shown in FIG. 1, in a state where the mounting bracket 11 is mounted on the ceiling panel 5, the resilient force of the pair of elastic locking pieces 24 causes the locking portion 26 to be engaged with both the engaging portions of the boss portion 13. The boss portion 13 can be drawn into the depth side of the ceiling panel 5 by pressing and engaging with the lower surface of the ceiling panel 5. Then, the flange 12 of the mounting bracket 11 can be pressed against the interior member 6 of the ceiling panel 5 by the retraction force based on the elastic force of the pair of elastic locking pieces 24, and the mounting bracket 11 is pressed against the ceiling panel 5. Can be mounted well without rattling.
In the above embodiment, the clip 21 is provided with a pair of elastic locking pieces 24, but the present invention is not limited to this, and the number of the elastic locking pieces 24 may be one, or three or more.
[0013]
【The invention's effect】
As described above, according to the present invention, a very simple operation of inserting the boss of the mounting bracket into the through hole of the ceiling panel and engaging the engaging portion of the boss with the elastic locking piece of the clip. Accordingly, the mounting bracket can be securely mounted on the ceiling panel, and the mounting cost can be reduced.
In addition, by engaging the engagement portions formed on both sides of the outer surface of the boss with the pair of elastic locking pieces of the clip, the mounting bracket can be prevented from rotating and mounted on the ceiling panel. Further, the engaging force of the boss portion by the elastic locking piece can be increased, and the mounting bracket can be more securely mounted on the ceiling panel. In addition, the locking portions of the pair of elastic locking pieces are pressed against and engaged with the lower surfaces of the pair of engaging portions of the boss portion, and the boss portion is pulled into the depth side of the ceiling panel, so that the mounting portion is attached to the ceiling panel. The bracket can be mounted more securely without rattling.
