DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sun visor provided at an upper portion on the front side of a passenger compartment to block sunlight entering a vehicle.

[0002]

2. Description of the Related Art FIGS. 6 and 7 show a conventional sun visor 1.
A frame 2 in which metal wires are bent in a substantially closed loop shape along the outer shape, a core material 3 disposed inside a closed loop formed by the frame 2, and hot melt bonding to both surfaces of the core material 3 A pad 5 made of urethane foam adhered via an agent 4 and a skin 6 covering the periphery of the pad 5 are provided.

The core 3 supports the pad 5 and the skin 6 from the inside to prevent them from hanging down. Corrugated cardboard is used because of its easy processing and light weight.

[0004] The core member 3 is attached to the frame 2 at appropriate intervals with tapes 7 formed in a U-shape, and is disposed in a closed loop of the frame 2 through the tape 7 as shown by hatching.

As the skin 6, a vinyl chloride sheet is used. After the sheet is cut into a shape and a size to wrap the pad 5, the pad 5 is wrapped, and the outer peripheral portions of the ends are butted. To cover the pad 5 by welding.

[0006] A support shaft 8 pivotally attached to the roof panel of the vehicle body is inserted into the sun visor 1 from above and attached thereto. Reference numeral 9 denotes a holder provided inside the sun visor 1 so as to be located around the support shaft 8 in order to secure the rigidity of the inserted portion of the support shaft 8.

[0007]

However, in the conventional sun visor 1, the skin 6 may be wrinkled at the corners and the slack 10 may be generated. This is because the sheet that is the material of the skin 6 has a difference in the amount of expansion and contraction in the vertical and horizontal directions.
When the temperature changes from a high temperature state to a normal temperature state during welding, the amount of contraction in the vertical and horizontal directions differs, and this difference in the amount of contraction is caused by concentration in the corner portion.

Means for suppressing wrinkles and slacks 10 on the skin 6 is to adjust the elasticity of the pad 5 inside the skin 6, that is, by selecting the specific gravity of the pad 5. Not only is it difficult to select a specific gravity that can prevent the slack 10, but also a suitable specific gravity changes depending on the conditions under which wrinkles and the slack 10 occur. For this reason,
It is difficult to reliably prevent wrinkles and looseness 10 by adjusting the specific gravity.

In addition to the occurrence of wrinkles and slacks 10 due to the difference in the amount of contraction, the skin 6 is pressed when the support shaft 8 is inserted.
Wrinkles and looseness 10 may occur.

Further, when the outer peripheral portion of the skin 6 is welded, a spark is generated between the inner frame 2 made of a metal wire and the electrode to be welded, and the spark is generated therebetween. May be scorched.

The occurrence of wrinkles and slacks 10 and the scorching of the skin 6 as described above cause deterioration of the appearance of the sun visor 1 and decrease in commercial value, which is not preferable. .

The present invention has been made in consideration of such conventional problems, and provides a sun visor having a structure capable of preventing generation of wrinkles and looseness on the epidermis and scorching due to sparks. The purpose is to:

[0013]

In order to achieve the above object, an invention according to claim 1 includes a frame formed in a substantially closed loop shape, a flat core material arranged in the closed loop of the frame, and In a sun visor comprising a pad covering both surfaces of the core material and a skin covering the periphery of the pad, and a support shaft from a vehicle body is inserted and attached to an upper side surface, outside a closed loop formed by the frame. The extended portion located is formed on the core material.

According to a second aspect of the present invention, there is provided the sun visor according to the first aspect, wherein the extending portion of the core member is provided outside a closed loop formed by the frame and at an insertion portion of the support shaft. It is characterized by being obtained.

According to a third aspect of the present invention, there is provided the sun visor according to the first aspect, wherein the extended portion of the core is provided outside the closed loop formed by the frame and at a bent portion of the frame. It is characterized by becoming.

The invention according to claim 4 is the invention according to claims 1 to 3.
The sun visor according to any of the above, wherein a lower portion of the lower frame portion does not have an extended portion of a core material, and is formed of a pad and a skin.

[0017]

According to the first aspect of the present invention, the outer skin is tensioned by the extended portion of the core located outside the frame. For this reason, there is no difference in vertical and horizontal contraction amounts in the epidermis, and wrinkles and looseness caused by the difference in contraction amounts are eliminated.

Further, since the core material is made of a non-metal and the extending portion is located outside the frame, the electrode for welding the skin does not approach the frame, and the spark caused by the approach causes the electrode to perform welding. It does not occur between. Therefore, the skin does not stick during welding.

According to the second aspect of the present invention, since the extended portion of the core provided at the insertion portion of the support shaft tensions the skin of the insertion portion of the support shaft, even if the skin is pushed by the support shaft. In addition, wrinkles and loosening of the epidermis do not occur.

According to the third aspect of the present invention, the extended portion of the core is provided at the bent portion of the frame, so that the skin of the bent portion of the frame is tensioned. For this reason, it is possible to prevent wrinkles and slackening from occurring at the corners.

According to the fourth aspect of the present invention, since the lower portion of the lower frame portion does not include the extended portion of the core material and is constituted by the pad and the skin,
Only the long pad formed at the lower portion of the lower frame portion is touched, and the feel of the operation on the sun visor is improved.

[0022]

FIG. 1 is an overall front view of an embodiment of the present invention, and FIGS. 2 to 5 are lines AA and BB in FIG.
It is sectional drawing in each part of a line, CC line, and DD line. The sun visor 11 of this embodiment includes a frame 12, a core 13, a pad 14, and a skin 15.

The frame 12 serves as an aggregate of the sun visor 1, and has a substantially closed loop shape by bending a metal frame. The frame 12 includes an upper frame portion 16, a lower frame portion 17, and left and right frame portions 18 and right and left frame portions 19, which are connected to each other. The free end of the right frame portion 19 is inserted into a holder 20 made of a synthetic resin molded product to which a leaf spring of a metal plate is assembled, and a closed loop state is maintained by this insertion. In this case, the support shaft 21 from the vehicle body is inserted into the holder 20, and the support shaft 21 and the sun visor 11 are connected by this insertion.

The core material 13 is used for imparting a predetermined hardness to the sun visor 11, and is arranged inside a closed loop formed by the frame 12, as shown by hatching in FIG. As the core material, cardboard, a resin plate, or other flat non-metals can be used. The attachment of the core material 13 to the frame 12 is performed by providing the tape 22 along the length direction of the frame 12 and wrapping the tape 22 over the frame 12 and the core material 13.

The core 13 has an extended portion located outside the frame 12 by extending a part thereof. The extended portion is provided in a portion where the skin 15 is likely to wrinkle or loosen. In this embodiment, the first extended portion 23 located on the outer portion of the upper frame portion 16 and the left frame portion 18 located on the outer part of
Are formed, and a third extending portion 25 located outside the right frame portion 19 is formed.

The third extending portion 25 is provided on the right frame portion 1.
It extends to the outer part between 9 and holder 20.

These extending portions 23, 24, 25 are formed by extending outwardly over the corresponding portion of the frame 12 while being in contact with the frame 12, as shown in respective cross sections.

Lower portion 30 of lower frame portion 17 (see FIG. 1)
However, the core material 13 is not extended, and only the pad 14 and the skin 15 are provided. This is to improve the feel of the operation on the sun visor 11. In other words, the hand of the occupant who operates the vehicle touches only the long pad 14 of the lower portion 30 of the lower frame portion 17.

The pad 14 enhances the feel during operation by imparting cushioning properties to the sun visor 11, and is made of a foam such as polyurethane foam. The pads 14 are arranged so as to sandwich the core 13 from both sides, and are joined to both surfaces of the core 13 by a hot-melt adhesive 26 applied in the length direction of the core 13.

The skin 15 imparts aesthetics to the sun visor 11, and a synthetic resin sheet such as a polyvinyl chloride sheet is used. The outer skin 15 is formed into a bag shape by wrapping the pad 14 in a sheet state, butting the outer peripheral portions surrounding the pad 14 and welding the butt portion with a high-frequency welder using an electrode.
2 to 5, reference numeral 27 denotes a welded portion of the joined outer skin 15.

The assembling of the sun visor 11 having the above structure is performed by bending a metal wire to form a closed loop frame 1.
2 and the core material 13 is
Attach to 2. Then, after applying the hot-melt type adhesive 26 to both sides of the core 13 so as to form a plurality of strips, the pads 14 are attached and sandwiched between the pads 14 of the core 13. Thereafter, the pad 14 is wrapped with the skin 15, and the outer periphery of the butted buttress 15 is welded by high-frequency welding and joined to attach the skin 15. In FIG. 2, reference numeral 28 denotes an electrode for performing high-frequency welder welding, which is performed so as to approach and sandwich the welded portion 27. The support shaft 21 on the vehicle body side is inserted into the sun visor 11 in a state where the welding has been completed from the upper side surface, whereby the sun visor 11 is mounted on the vehicle body.

In such a sun visor 11, extended portions 23, 24, 25 of the core material 13 extend to the outside of the frame 12 at portions where wrinkles and loosening are likely to occur on the skin 15.
The skin 15 at a portion facing the extending portions 23, 24, 25
Is tensioned by the extension.
In this tensioned state, there is no difference in the amount of contraction in the vertical and horizontal directions on the skin 15, and wrinkles and looseness caused by the difference in the amount of contraction do not occur on the skin 15.

In particular, the second extending portion 24 and the third extending portion 25 are close to the bent portion of the frame 12, in which the outer skin 15 is more likely to contract more in the horizontal direction than in the vertical direction. By thus extending the core material 13 to a portion close to the bent portion, it is possible to effectively prevent wrinkles and loosening due to differences in the amount of contraction.

Since the core 13 is made of non-metal and the extending portions 23, 24 and 25 are located outside the frame 12, the electrode 2 for welding the skin 15 is formed as shown in FIG.
8 does not approach the frame 12 (in this case, the upper frame 16). For this reason, a spark caused by the approach to the frame 12 does not occur between the frame 12 and the electrode 28, and the spark causes the outer skin 1 to be welded by the spark.
5 is no longer scorched.

The lower portion 30 of the lower frame portion 17 has a longer pad 14 as shown in FIG. 2, and a sufficient distance L is formed between the lower frame portion 17 and the electrode 28. Therefore, since the electrode 28 does not approach the lower frame 17, no spark is generated in this portion, and the skin 15 is not scorched.

Further, the third extending portion 25 of the core 13 is
The support shaft 21 is extended to an insertion portion where the support shaft 21 is inserted, and the skin 15 of the support shaft 21 insertion portion is in a tensioned state.

For this reason, even if the skin 15 is pushed by the support shaft 21 when the support shaft 21 is inserted, the skin 15 is maintained in a tensioned state, so that wrinkles and slack do not occur.
