Description

[Detailed Description of the Invention] <<Field of the Invention>> This invention relates to a sun visor with a mirror, and in particular to an improvement of a sun visor with a lid (hereinafter referred to as lid) that can be opened and closed on the mirror surface of the mirror.

《Prior art and its problems》 As a conventional technology of this type,
There is an original application published in No. 1, and a modified application from JP-A-53-102535.

This sun visor has a mirror embedded in the sun visor body, and in the sun visor's high-frequency welding process, the pad material and skin material corresponding to the periphery of the mirror are sealed and integrated, leaving one side open and closed. It forms a lid.

When such a lid is provided, since shape retention cannot be maintained with just the skin material and pad material, a reinforcing plate and a skin material on the back side are buried inside in advance in a laminated state. In the seal cutting step, the hard lid is formed to be openable and closable.

In such a sun visor with a mirror, the skin material on the back side of the lid is made of vinyl chloride, the same as the skin material that makes up the entire sun visor body, so the strength of this part is extremely weak and it is difficult to open and close it repeatedly. During this process, cracks appeared in some parts along the hinge part, and the cold-resistant hinge properties were extremely poor.

For this purpose, in the prior art described above, a cloth is interposed between the back side skin material and the front side skin material,
This allows for a structure that increases strength.

However, with such a configuration, each member is sequentially laminated on the mold when sealing and cutting them together during high-frequency welding, but in such a case where the parts are installed only in one part, Positioning is difficult, and the fabric is not always located at the hinge, leading to greater product variation and an increase in the number of parts.

In addition, even though the cold resistance strength characteristics are improved in this way, the back side of the lid is still made of vinyl chloride, so it becomes hard at low temperatures, and the mirror is made of transparent resin such as acrylic. Many products have aluminum evaporated on the back side, so if they become hard in cold weather, they can be opened and closed repeatedly.
The mirror surface is easily scratched, leading to faster deterioration of the product.

<<Purpose of the invention>> The purpose of this invention is to reduce the number of parts required to obtain the above-mentioned cold resistance characteristics, and to prevent scratches on the mirror surface due to opening and closing of the lid in cold weather.

《Structure and effects of the invention》 In order to achieve the above object, this invention includes a mirror held on the core frame of the sun visor body, a locking magnet embedded in the back of the mirror, and a locking magnet embedded in the mirror on the surface of the mirror. It includes a laminated back skin material, a reinforcing plate, an iron piece attracted by the magnet, and a pad material and skin material that surround each member and constitute the outer shape of the sun visor body. The mirror surface of the mirror is exposed by seal-cutting the position facing the mirror surface using high-frequency welding means, leaving only one side, and the back surface material, the iron piece,
In a sun visor with a mirror, which is formed by forming a lid that can be opened and closed by integrating a pad material and a skin material, the skin material is made of woven fabric or non-woven fabric, and one side of the lid is extended to the uncut side. The present invention is characterized in that a thin hinge portion constituted by one side of the back skin material and the skin material is formed by pressing along one side by high frequency welding.

In the above configuration, since the back skin material is made of woven fabric or nonwoven fabric, the strength of the hinge portion formed between the back skin material and the skin material is increased, and the cold-resistant hinge characteristics are also improved. There are no positioning problems and the number of parts is reduced.

In addition, in this invention, since the surface facing the mirror surface of the mirror is a soft surface made of woven or non-woven fabric, the mirror surface will not be damaged even if it is opened and closed repeatedly, and the durability of the mirror surface can be improved. Improves sex.

<<Description of Embodiments>> FIG. 1 shows an exploded view of a sun visor with a mirror to which this invention is applied.

The sun visor body is formed by laminating pad materials 2, 3 and skin materials 4.5 in a sandwich pattern on both sides of a core frame 1 made of wire or the like, and welding and cutting the periphery using a high-frequency welder to form the desired plate shape. It is something to do.

The core frame 1 includes a frame body 6 made of wire or the like, and a shaft holder 7 provided on one side of the frame body 6.
and a shaft 8 whose one end is inserted through the shaft holder 7 and whose other end is attached to the vehicle body side (not shown), and a mirror holding frame 9 is spanned over both sides of the frame body 6. .

A mirror 10 is mounted on the upper surface of this mirror holding frame 9.
A locking permanent magnet 11 is installed on the back side of the mirror 10, and the pad material 2 and the skin material 4, which face the mirror 10, are provided with one side remaining as shown in FIG. A seal cut 4a is formed as shown by the chain line, and a member is arranged on the mirror surface of the mirror 10 between the skin material 4 and the pad material 2 to make the cut out portion a lid 15.

These members include a back skin material 12 made of woven fabric or non-woven fabric, a reinforcing plate 13 installed on the top of this back skin material 12, and a reinforcing plate 13 installed on the reinforcing plate 13 to face the installation position of the permanent magnet 11. and a back skin material 12.
On one side, an extension portion 12a is formed to extend toward the uncut side.

In a sun visor constructed from the above-mentioned material configuration, the materials are laminated in accordance with the lamination order shown in the figure, set in a mold of a high-frequency welding device, engaged with the molds, and bonded to both molds. By applying high frequency waves between them, the peripheral edges of the skin materials 4 and 5 of the sun visor body are welded and fused to form the outer shape of the sun visor body, and the surfaces of the skin material 4 and pad material 2 are A seal is cut along the chain line portion, and the back skin material 12 and the reinforcing plate 1 are cut.
3 and the iron piece 14 have their peripheral edges integrated with the cutout pad material 2 and skin material 4, and the lid 15
becomes.

FIG. 2 shows a vertical sectional view of the main part in the assembled state.

Here, one side of the lid 15 is pressed between both molds during the high-frequency welding process, and is thinned, and the skin material 4 and the crushed pad material 2 are thinned.
A thin-walled hinge 16 is formed between the cover and the extended end 12a of the back skin material, and the structure is rotatable about the hinge 16.

When the lid 15 is closed, the iron piece 14 buried on the side of the lid 15 is attracted to the permanent magnet 11, thereby locking it in the closed state.

Further, when the lid 15 is opened from this state, it opens to the lower side via the hinge 16, and the mirror surface of the mirror 10 provided inside can be seen.

Therefore, when the lid 15 is closed, it is rapidly pulled by the attractive force of the magnet 11 at its final closed position, and the back surface material 12 of the lid 15 is pulled close to the mirror 1.
However, since the back side skin material 12 is made of woven fabric or non-woven fabric, the contact is extremely soft, and therefore the mirror surface does not come into contact with the mirror surface when opening and closing frequently. Scratches are prevented.

Furthermore, since the hinge 16 is made from a combination of woven or non-woven fabric and the surface material 4 on the front side, the strength of this part is extremely high, and moreover, compared to the conventional one made only of vinyl chloride. This also improves the cold-resistant hinge characteristics.

In addition, as the material of the woven fabric or non-woven fabric constituting the back side skin material in the above examples, a material with good high frequency welding properties is selected, or vinyl chloride etc. is laminated on the back side of the woven fabric or non-woven fabric. If a material is used, the adhesive force with the surface skin material will be greater.
