Description

[Detailed description of the invention] (Field of industrial application) This invention relates to the fixing structure of the bearing case of a vehicle sun visor. This invention relates to a structure for fixing a synthetic resin bearing case having a bearing part.

(Prior Art) Conventionally, in order to maintain the shape of the sun visor body, a flat core board corresponding to the shape of the sun visor body is installed inside the sun visor body, and a support shaft is attached to a predetermined position of the core board. There is a type in which the bearing case is fixed. This bearing case was generally made of metal and fixed to a predetermined position on the core board with rivets or the like.

(Problems to be solved by the invention) In the above-mentioned conventional device, since the bearing case is made of metal, the rotating part between the bearing case and the support shaft inserted into the shaft hole of the case may be rusted, etc. This may cause trouble in rotating the sun visor body around the support shaft. In addition, in the case of fixing the bearing case to a predetermined position of the core board with rivets, there is a process of forming through-holes for the rivets at predetermined positions of the core board and the bearing case, and a process of forming through-holes across these through-holes. The process of inserting a rivet through the rivet and caulking the rivet is required.
Another problem was that it took a lot of time and effort to fix the bearing case.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, in this invention, a bearing part for a support shaft is provided at a predetermined position of a core board installed inside the sun visor body. In order to fix the synthetic resin bearing case, a locking groove is formed in the bearing part of the bearing case along its shaft hole, and a locking member fixed to a predetermined position of the core board has the locking groove formed in the bearing part of the bearing case. The structure includes an elastic locking portion that is fitted into the locking groove of the bearing portion and engages in elastic pressure contact with the wall surface of the locking groove.

(Function) Therefore, in this invention, the bearing case is made of synthetic resin, thereby preventing rusting of the rotating part between the bearing case and the support shaft, and making it possible to rotate the sun visor body around the support shaft. In addition, by bringing the elastic locking part of the locking member fixed to a predetermined position of the core board into elastic pressure contact with the groove wall surface of the locking groove formed in the bearing part of the bearing case, The bearing case is fixed to the core board.

(Example 1) Example 1 of this invention will be described below with reference to FIGS. 1 to 6.

In FIG. 5, which shows a partially cutaway front view of a vehicle sun visor, and FIG. 6, which shows a side cross section, an L-shaped support shaft 2 is attached to a mounting member 1 that is fixed to a predetermined position on the vehicle body. It is rotatably supported at its vertical shaft portion 2a. A sun visor main body 3 is rotatably mounted on the horizontal shaft portion 2b of the support shaft 2 in a bearing case 4 provided inside the main body.

The sun visor body 3 includes a core board 5 formed into a predetermined shape from a plate-like member such as cardboard, a synthetic resin board, or a plywood board, and a pad 6 surrounding the core board 5 and made of a sponge material or the like divided into front and back sides. and an exterior skin 7 covering the pad 6, and a bearing case 4 is fixed to a predetermined position of the core board 5 by a locking member 8.

The bearing case 4 is integrally molded by injection molding of a synthetic resin material, and as shown in FIGS. 1, 2, and 4, the horizontal shaft portion 2b of the support shaft 2 is rotatably fitted into the bearing case 4. A cylindrical bearing part 4a having a shaft hole to be inserted in the center, and a cylindrical bearing part 4a extending from the outer periphery of the bearing part 4a,
and a pair of legs 4b along both the front and back sides of the core board 5.
It is mainly composed of. And bearing part 4
A locking groove 9 having an arcuate cross section along the shaft hole is formed in an open shape between the pair of legs 4b, 4b.

The locking member 8 for fixing the bearing case 4 to a predetermined position on the core board 5 is formed by bending a thin elastic metal plate such as an iron plate, and the upper part thereof includes: As shown in FIGS. 1 and 3, an elastic locking portion is formed which is fitted into the locking groove 9 of the bearing case 4 and engages with the groove wall surface of the locking groove 9 by elastic pressure contact. There is. In this embodiment, the elastic locking portion 8a is composed of an arcuate portion 8b having an arcuate cross section, and folded portions 8c, 8c each folded back into a substantially arcuate shape from both ends of the arcuate portion 8b. And both folded parts 8c, 8c
A pair of support legs 8d, 8d extend in parallel from both ends of the core board 5 along both the front and back sides of the core board 5, and the support legs 8d, 8d are fixed to the core board 5 by stitch caulking 10. .

This embodiment is constructed as described above. Therefore, when fixing the core board 5 to the synthetic resin bearing case 4 at a predetermined position, the locking groove 9 of the bearing case 4 is Elastic locking portion 8 of locking member 8
a, and the elastic locking portion 8a is brought into elastic pressure contact with and engaged with the groove wall surface of the locking groove 9, thereby integrally joining the locking member 8 and the bearing case 4. Then, both support legs 8d, 8d of the locking member 8 are placed along both the front and back sides of the core board 5, and these support legs 8d, 8d are placed along both sides of the core board 5.
By fixing d to the core board 5 with stitches 10 to 10, fixing of the bearing case 4 to the core board 5 is completed.

(Example 2) Next, Example 2 of this invention will be described with reference to FIGS. 7 to 10.

In this second embodiment, the locking member 8 is modified, and a plurality of mounting holes 15 to 15 for the locking member are provided at predetermined intervals in predetermined positions of the core board 5. Locking members 8 to 8 are attached to these attachment holes 15 to 15, respectively. Each of these locking members 8 to 8 is formed by bending an elastic flat strip material such as a steel plate, and as shown in FIG. 7 and FIG. A pair of support legs 8d, 8d are bent upward at right angles along both the front and back surfaces of the core board 5 at both ends of the support portion 8e that is inserted into the core board 5. 8d is fitted into the locking groove 9 of the synthetic resin bearing case 4,
Elastic locking portions 8a, 8a that engage the groove wall surface of the locking groove 9 in elastic pressure contact are formed in an arcuate shape.

Therefore, in this second embodiment, first, each of the locking members 8 to 15 is attached to each of the mounting holes 15 to 15 of the core board 5.
8, one of the elastic locking portions 8a and the support legs 8d are elastically deformed and inserted, and the support portions 8e of each of the locking members 8 to 8 are fitted into the respective mounting holes 15 to 15 of the core board 5.
Attach each locking member 8 to 8 to. Next, the elastic locking portions 8a, 8a of each of the locking members 8 to 8 are fitted into the locking groove 9 of the bearing case 4, and these elastic locking portions 8
By bringing a and 8a into elastic pressure contact with the groove wall surface of the locking groove 9, the fixation of the bearing case 4 to the core board 5 is completed.

(Effects of the invention) As described above, according to this invention, by making the bearing case made of synthetic resin, it is possible to prevent the rotating parts of the bearing case and the support shaft from rusting, etc. The sun visor main body can be rotated smoothly around the support shaft with a predetermined torque, and the sun visor body can be made lighter and safer than a metal one. In addition, the synthetic resin bearing case is fixed to the core board by fitting the elastic locking part of the locking member fixed to the bearing case into the locking groove of the bearing case and making elastic pressure contact with the groove wall surface. There is also the effect that it can be easily performed by engaging with each other.
