Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view of a sun visor for a vehicle with a vanity mirror, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, FIG. 3 is a cross-sectional view showing an overturn mechanism of a mirror cover, and FIG. 5 is an enlarged view of a portion C in FIG. FIG. 6 is a cross-sectional view showing a state before the split cores constituting the sun visor main body are joined. As shown in FIG. 1, a vehicle sun visor 1 with a vanity mirror formed in a horizontally long substantially rectangular shape can be mounted on a front end of a ceiling of an automobile via a mounting arm 1a provided at one end on an upper edge side. The shaft 1b provided at the other end is supported by a support hook (not shown) mounted on the front end of the ceiling of the vehicle.

The sun visor body 2 of the sun visor 1 is made of a hard synthetic resin such as a polypropylene resin, and in the present embodiment, as shown in the sectional views of FIGS. It is composed of two divided cores 2a and 2b on the front side and the rear side. Two divided cores 2 constituting the sun visor body 2
a and 2b are formed into a predetermined shape by injection molding using a molding die, and are joined by a plurality of elastically deformable engaging claws 14 projecting from the back surface side by snapping action of each other. It is possible, and in the joined state, a hollow sun visor main body 2 is configured (see FIG. 4). In addition,
The joining of the split cores 2a, 2b is performed in the final step of the assembling process.

A mirror mounting portion 4 as a vanity mirror mounting portion is provided at a substantially central portion of one (front side) split core 2a.
, Valve unit mounting part 5 and mirror cover mounting part 6
Are formed. The mirror mounting part 4 has an opening 4a formed in a horizontally long rectangular shape as shown in FIG.
And a mounting groove 4b formed over the entire inner peripheral surface of the opening 4a, and the outer peripheral edge of the mirror 7 is fitted and supported in the mounting groove 4b. .

As shown in FIG. 2, the valve unit mounting portion 5 is formed at a position adjacent to the mirror mounting portion 4. The valve unit mounting portion 5 is constituted by a vertically long concave portion which is recessed at a predetermined depth toward the back surface side. The valve unit mounting portion 5 includes a valve body 8a, a valve 8b, an electrode plate 8c, a lens 8d and the like. Is assembled to the valve unit 8.

The sun visor body 2 is provided with a mirror cover 10 for covering the area where the mirror 7 and the valve unit 8 assembled as described above are arranged. The boss portion 10a provided on the side is supported by the mirror cover mounting portions 6 formed at two places on the left and right sides of the upper edge portion side of the mirror mounting portion 4 so as to be openable and closable. As shown in FIG. 3, the mirror cover mounting portion 6 includes a pair of a pin receiving portion 6a and a hinge pin supported by the pin receiving portion 6a and rotatably supporting the boss portion 10a of the mirror cover 10. 9. The hinge pin 9 is inserted sideways into the pin holes of the pin receiving portion 6a and the boss portion 10a on the back surface side of the split core 2a and assembled.

On the back surface near the center of rotation of the mirror cover 10, a turnover leaf spring 11 for holding the mirror cover 10 in an open position or a closed position is assembled to the split core 2a. As shown in detail in FIG. 5, the leaf spring 11 has one end inserted into the mounting notch 6b formed in the split core 2a and locked in a retaining state, and the other end serving as a pressing portion. The portion 11a is pressed against the boss 10a of the mirror cover 10.

The leaf spring 11 is provided on the mirror cover 10.
In the closed state, as shown by a solid line in FIG. 5, a force in the closing direction is applied to the mirror cover 10 by abutting on a planar closing-side contact surface 10b formed on the boss 10a, In the state where the mirror cover 10 is opened, as shown by the imaginary line in FIG. 5, a force in the opening direction is applied to the mirror cover 10 by abutting the flat opening-side contact surface 10 c. Is set. In other words, the leaf spring 11 is set so that the direction of action of the force is reversed with respect to the boundary between the two contact surfaces 10b and 10c.

The closing-side contact surface 10b and the opening-side contact surface 10c are approximately 10 degrees with respect to the rotation direction of the mirror cover 10.
It is set with a phase difference of about 0 degrees. The boundary between the contact surfaces 10b and 10c is formed in a curved shape, so that the mirror cover 10 can be smoothly turned over when the mirror cover 10 is opened and closed.

The entire surface of the sun visor body 2 is covered with a skin 12 constituting a design surface.
In this case, the skin 12 is coated on each of the divided cores 2 a and 2 b constituting the sun visor body 2. That is, the divided core 2a is covered with the divided core 2a on the front side and the divided core 2b on the back side, and the terminal is wound around and joined to the back side of the divided core. Also, the split core 2 on the front side
A narrow groove 13 having a horizontally long rectangular shape and surrounding the setting area of the vanity mirror is formed on the rear side. An opening corresponding to the vanity mirror setting area is formed in the skin 12, and the opening end is formed in the narrow groove 1.
3

The vehicle sun visor 1 with the vanity mirror according to the present embodiment is configured as described above. That is, the sun visor body 2 is divided into the divided cores 2a, 2
b, a mirror mounting portion 4 as a vanity mirror mounting portion, a valve unit mounting portion 5, and a mirror cover mounting portion 6 are formed on the front split core 2a, and a vanity mirror configuration is formed on each of these mounting portions. Mirror 7, valve unit 8, and mirror cover 10, which are parts
Is directly assembled. For this reason, the sun visor main body 2 also serves as an assembly body of the vanity mirror, and after manufacturing the vanity mirror unit, the number of parts and the number of assembling steps are reduced as compared with the conventional case where the vanity mirror unit is assembled to the sun visor main body. And a reduction in production cost can be achieved.

In this embodiment, the end of the opening of the skin 12 covering the surface of the sun visor body 2 is fitted and fixed in the narrow groove 13 formed around the vanity mirror mounting portion in the sun visor body 2. Configuration.
It can be finished easily and neatly, and the appearance can be improved. In addition, since the sun visor body 2 is constituted by the split cores 2a and 2b, and one of the split cores 2a is provided with a vanity mirror attaching portion, it is possible to assemble the components of the vanity mirror from the surface side of the split core 2a. Of course, the hinge pins 9
And the leaf spring 11 can be assembled.

Furthermore, since the two split cores 2a and 2b are joined by utilizing the snap action of the locking claws 14, the joining operation can be performed easily and quickly. In the present embodiment, when molding the sun visor body 2,
Since the vanity mirror mounting portion, that is, the mirror mounting portion 4, the valve unit mounting portion 5, and the mirror cover mounting portion 6 can be formed at the same time, the number of manufacturing steps can be reduced.

In the present embodiment, the case where the sun visor main body 2 is formed by injection molding has been described. However, the present invention is not necessarily limited to this method, and may be formed by, for example, blow molding. In the case where the sun visor body 2 is composed of the split cores 2a and 2b, the split cores 2a and 2b are joined by a snapping action of the elastically deformable locking claws 14, but the invention is not limited to this. There is no harm in changing to the fastening type. Further, the open / close fulcrum of the mirror cover 10 is not limited to the upper side but may be the lower side.

[0021]

As described in detail above, according to the present invention,
In a vehicle sun visor with a vanity mirror, a vanity mirror mounting portion is integrally set on the sun visor body, and a vanity mirror component is assembled to the vanity mirror mounting portion, so that the vanity mirror unit is manufactured in advance. The number of parts and the number of assembling steps can be reduced as compared with a conventional structure in which the sun visor is assembled to the sun visor body, and waste in production can be reduced.
