Description

[Detailed Description of the Invention] <Field of the Invention> This invention relates to an automobile sun visor using a hollow resin core material, and particularly for an automobile in which a bracket is securely and firmly fixed inside the resin core material. Regarding sun visor.

<Prior art and its problems> For example, as a conventional example of a sun visor in which a bracket is fixed inside a hollow resin core material, the present applicant has previously filed Japanese Patent Application No. 62-
No. 289517 has been filed.

Although not specifically shown, the structure of the sun visor of this prior application is that the main body of the sun visor is rotatably supported on the vehicle body.First, a locking means is newly provided on the vehicle body ceiling, and the sun visor is locked by the locking action of the locking means. The sun visor main body is rotated downward by its own weight by locking the main body in a state where the main body is almost in close contact with the ceiling of the vehicle body and conversely unlocking the locking means.

Then, a drive gear, which is keyed to the outer circumference of the rotating shaft that supports the sun visor body and has external teeth engraved in a portion of the outer circumference area, and a bracket fixed inside the sun visor body, through a braking member. The sun visor body is rotatably supported and has a driven gear with external teeth engraved on the entire outer circumference. When the drive gear and the driven gear do not mesh with each other, the sun visor body freely rotates downward due to the weight of the sun visor body. However, when the drive gear and the driven gear mesh with each other, the braking force of the braking member such as a leaf spring provided on the driven gear does not cause the sun visor to freely fall due to the weight of the sun visor, and the force that overcomes the braking force of the braking member, By manually rotating the sun visor body downward, the sun visor body can be rotated to the angle necessary for the sunshade, and the sun visor body can be set to its rotation position by the braking force of the braking member. So that the can be held to.

In this prior application example, the bracket mounting structure is such that a screw fixing boss is erected on the inner side surface of the hollow resin molded body that constitutes the core material of the sun visor body, and is fixed to the boss by screw fixing. Although the bracket is fixed to the core material by the above, there is a problem that screws are dropped from the boss or the boss is broken because the turning torque is extremely high during the turning operation of the sun visor body. It was pointed out.

<Purpose of Invention> The present invention was made to solve the above-mentioned problems. The purpose of the present invention is to provide a hollow core material obtained by polymerizing half-molded resin moldings. It is intended to improve the quality performance of the sun visor for automobiles by firmly and securely attaching the bracket.

<Constitution and effect of device> In order to achieve the above object, the present invention comprises a hollow resin core material obtained by polymerizing half-divided resin moldings, and a skin material covering the outer periphery of the core material. In an automobile sun visor having a billet fixed inside the sun visor body, a screw fixing boss portion for fixing the bracket with a screw and a pressing protrusion for pressing and holding the bracket are provided on the opposing inner side surfaces of the resin core material. It is characterized in that the periphery of the screw head of the billet formed and fixed to the boss portion with screws is pressed and held by the pressing projection.

That is, according to the above configuration, the bracket fixed to the inside of the resin core with the screws is in a state of being sandwiched from the front and back sides by the screw-holding boss portion and the pressing protrusions. Even if external force is applied to the bracket,
Since the front surface of the bracket is pressed by the pressing protrusion, the bracket does not fall off or the base of the boss is destroyed, and the bracket can be mounted securely and firmly inside the sun visor body, and the sun visor for automobiles Has the advantage of significantly improving the quality performance of.

<< Description of Embodiments >> Hereinafter, one embodiment of an automobile sun visor according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are a side view and a sectional view showing the relationship between the sun visor body and the rotating shaft, and FIGS. 3 (a) to 3 (c).
Is an explanatory view showing the relative relationship between the drive gear and the driven gear at the rotational angle position of the sun visor body, and FIG. 4 is a sectional view showing the mounting structure of the bracket that supports the driven gear, and FIG. The figure is a perspective view of the sun visor of the present application as viewed from the indoor side.

In FIG. 1, a drive gear 3 is keyed to an outer peripheral surface of a substantially L-shaped rotating shaft 2 that rotatably supports a sun visor body 1, and an outer peripheral region of the drive gear 3 is formed. External teeth are engraved on a part of each of the teeth, and a gear portion 3a and a non-gear portion 3b are formed.

A driven gear 4 is installed corresponding to the drive gear 3. The driven gear 4 is mounted on a bracket 5 fixed inside the sun visor body 1 and a braking member 6 such as a leaf spring.
It is rotatably supported via.

The relationship between the drive gear 3 and the driven gear 4 will be further described. First, FIGS. 1 and 2 show the case where the sun visor body 1 is stored in a state in which it is in close contact with a ceiling surface (not shown). At this time, the non-gear portion 3b of the drive gear 3 and the driven gear 4 correspond to each other. That is, in FIGS. 3 (a) to 3 (b), since the drive gear and the driven gear 4 do not mesh with each other, the sun visor body 1 is attached to the rotating shaft 2 by the weight of the sun visor body 1.
Will fall down freely.

Then, in order to rotate the sun visor body 1 further downward from FIG. 3 (b), the gear portion 3a of the drive gear 3 and the outer teeth 4a of the driven gear 4 mesh with each other, so that the driven gear 4 is moved to the sun visor body. The driven gear 4 is rotated by the rotating operation of the driven gear 4. However, the braking action of the braking member 6 such as a leaf spring provided between the both ends 4b of the driven gear 4 and the bracket 5 causes the driven gear 4 to rotate.
The rotation of the is restricted, and a predetermined rotation torque is obtained.

That is, when in the use position from FIG. 3 (b) to FIG. 3 (c), the sun visor body 1 does not fall freely due to its own weight, and the sun visor body 1 is reliably positioned at any predetermined position. It is configured to be lockable.

The remarkable point of the present invention is that the bracket 5 is securely and firmly attached to the inside of the sun visor body 1 as shown in FIG.

That is, as described above, the meshing relationship with the drive gear 3 and the driven gear 4 is used to rotate the driven gear 4 by using the braking force of the braking member 6 to rotate the sun visor body 1 during the rotating operation. In the sun visor of the type which obtains the above, the turning torque is usually as high as about 30 kg · cm, so that a firm mounting strength is required even in the mounting structure of the bracket 5 which supports the driven gear 4.

First, the sun visor body 1 is composed of a core material 1a made of a hollow resin molding and a skin material 1b having a cushioning property for covering the surface of the core material 1a, and the inner surface of the core material 1a. In the state where the boss portion 7 for screwing the bracket 5 to the screw and the pressing projection 8 for pressing and holding the bracket 5 against the boss portion 7 face each other, a screw stopper opened on both sides of the bracket 5 It is provided so as to match the hole 5a.

Therefore, as shown in the drawing, the bracket 5 is attached to the boss portion 7
In the state where the brackets 5 are fixed to each other by the screws 9, both side portions of the bracket 5 are held together by the boss portion 7 and the protrusion 8.
Even if a very strong turning torque is applied in the direction of the arrow in FIG. 4 during the turning operation of the sun visor body 1, the surface of the bracket 5 is pressed and held by the projection 8, so that the screw 9 may fall off or the boss may drop. The base portion of the portion 7 is not broken, and the bracket 5 is the core material 1a of the sun visor body 1.
Therefore, the conventional problems can be effectively solved.

Next, for reference, the structure when the sun visor of the present application is unlocked from its stored state and rotated is described with reference to FIG. 5, and as shown in FIG. While the recess 10 is formed in the center, the lock button 12 is provided on the ceiling 11 side, and the lock button 12 is engaged in the recess 10 to lock the sun visor body 1 in a state in which it is in close contact with the ceiling 11. On the contrary, by releasing the engagement of the lock button 12, the sun visor body 1 is freely rotated downward by its own weight.

Although not specifically shown, the lock button 12 is normally urged in the engagement direction with the recess 10 by a spring pressure such as a torsion spring, and if the sun visor body 1 is rotated upward, It goes without saying that the engagement with the recess 10 can be automatically released by automatically engaging the recess 10 and operating the lock button 12 against the spring pressure by a torsion spring or the like. .

As described above, in this embodiment, the gear meshing type sun visor is applied to the mounting structure of the bracket 5 that supports the driven gear 4. However, for example, a bracket for mounting a leaf spring for extracting a torque for rotation and a bracket for fixing a cosmetic mirror are used. It may be applied to a structure in which is fixed inside the core material.
