A reinforcing bar inserted inside the shade portion is provided, and an upper portion of the reinforcing bar is fixed to the bearing member, and a lower portion of the reinforcing bar is fixed to the core material of the sunshade portion .
[0005]
[Action]
Since the distance between the bearing member and the hook is constant, the support portion can be formed as having a constant size and shape even when the sun visor is different. On the other hand, the sunshade has a size corresponding to the size of the sun visor body for each vehicle type. With this configuration, since the size and shape of the support portion are constant, the bearing member can be arranged at a fixed location on the support portion. In addition, since the bearing member is shared for each sun visor, the number of manufactured members increases. Therefore, the bearing members can be mass-produced, thereby improving the manufacturing efficiency. On the other hand, the sunshade requires the same number of types as the sun visors, but since the sunshade does not include a bearing member, its manufacture is easy. Therefore, the manufacturing efficiency of the sun visor body is improved as a whole.
In addition, various types of cards such as parking tickets can be inserted between the halves and the sunshade in the area where the sunshade is sandwiched by the pair of halves, and the sandwiched area is used as a kind of card holder. can do.
Furthermore, by inserting the positioning projections formed in the pair of halves into the through holes formed in the sunshade, the sunshade can be reliably prevented from dropping off the support.
When the sunshade is constituted by a core material, a cushion material and a skin for accommodating these from the upper end opening, usually, after the core material and the cushion material are accommodated in the skin, the upper end opening of the skin is removed. It must be closed by welding. However, when the upper end of the sunshade is sandwiched and fixed by the pair of halves, it is not necessary to close the upper end opening. Therefore, the manufacturing cost can be reduced accordingly. In addition, when welding is performed, burrs are generated and the beauty is impaired.However, such a problem can be prevented by sandwiching and fixing the sunshade portion with a pair of halves, and the burrs can be prevented. The labor such as resection can be saved.
Furthermore, when rotating the sun visor with the sunshade portion when rotating the sun visor main body, a large stress is concentrated on the portion where the half body is sandwiched by the sunshade portion. For this reason, the sunshade may be deformed from the pinched portion. However, in the sun visor of the present invention, the upper and lower portions of the reinforcing bar are respectively inserted into the support portion and the sunshade portion, and the upper and lower portions are fixed to the bearing member and the core material of the sunshade portion, respectively. As a result, most of the stress acting on the sandwiched portion of the sunshade is handled by the reinforcing bar. Therefore, it is possible to prevent the sunshade from being deformed at the sandwiched portion. The stress acting on the holding portion can be reduced by increasing the width of the support portion in the vertical direction and moving the holding portion of the half body to the sunshade portion away from the stay, which is the center of rotation of the sun visor, downward. However, in such a case, the ratio of the support portion to the entire sun visor main body increases, so that the beauty of the sun visor main body is impaired.

【Example】
An embodiment of the present invention will be described below with reference to FIGS.
As shown in FIG. 1, the vehicle sun visor A according to the present invention also includes a sun visor body 5, a stay 8, and a hook 9 (see FIG. 3). The sun visor main body 5 includes a support portion 6 and a sunshade portion 7. The stay 8 and the hook 9 are arranged on the ceiling of the vehicle in the same manner as in the prior art, with their axes oriented horizontally and aligned with each other. The shape and the structure are the same as those of the well-known one, and are not the characteristic parts of the present invention, and therefore, the description thereof is omitted.
[0007]
First, the sunshade portion 7 will be described. As shown in FIG. 1B, the sunshade portion 7 includes a core 7A, a cushion 7B, and a skin 7C. The core 7A is for maintaining the shape of the sunshade 7 and is made of cardboard made of a resin such as polypropylene or paper. The hole of the cardboard is oriented vertically in FIG. The cushion material 7B is arranged so as to surround the entire core material 7A. The outer skin 7C is formed by sewing the periphery of two cloths made of a tricot or the like into a bag shape with an upper part opened, and the core material 7A and the cushion material 7C are inserted into the inside from the upper opening part. . In addition, a through hole 71 is formed at an appropriate position above the sunshade 7.
[0008]
Next, the support portion 6 will be described. The support portion 6 is configured by joining a pair of support portion halves 6A and 6B to each other. The pair of supporting portion halves 6A and 6B are formed by molding a relatively hard resin, and are formed identically (symmetrically) to each other except for a part of the structure. Therefore, here, only one half 6A will be described, and for the other half 6B, only different portions will be described, and similar portions will be denoted by the same reference numerals and symbols B, and description thereof will be omitted. .
[0009]
On a surface of the half body 6A facing the half body 6B, a protruding portion 61A extending along the peripheral edge is formed. The height of the protrusion 61A is higher on the upper side (upper side in FIG. 1A) of the half body 6A, and lower on both sides and the lower side. Therefore, when the pair of halves 6A and 6B are abutted against each other, the upper portions of the halves 6A and 6B are in close contact with each other, but the both sides and the lower portion face each other away from each other. The awning 7 is fixed to the support 6 by the upper portion of the awning 7 being clamped.
[0010]
A positioning protrusion 62A is formed at a lower portion of a surface of the half body 6A facing the half body 6B. The positioning projections 62A, 62B of the respective halves 6A, 6B are inserted into the through holes 71 of the sunshade portion 7, thereby positioning the sunshade portion 7 and dropping the sunshade portion 7 from the support portion 6. To prevent you from doing so.
[0011]
The pair of halves 6A and 6B are fixed by bonding the portions where the protruding portions 61A and 61B are high to each other. In this embodiment, the halves 6A and 6B are replaced with or together with the bonding. , 6B are secured to each other by clips 10 locked to the projections 63A, 63B. Reference numeral 64A is a claw for positioning the halves 6A and 6B.
[0012]
A storage space 65 surrounded by the protruding portions 61A, 61B is formed between the pair of halves 6A, 6B. The bearing member 11 is disposed and fixed at an upper portion on one end side of the storage space 65. The bearing member 11 has a tubular portion 111 into which the stay 8 is rotatably inserted, similarly to a well-known one, and a flat portion 112 is formed by cutting and raising a part of the tubular portion. Is formed. When the flat plate portion 112 comes into contact with the outer peripheral surface of the stay 8 in an elastically deformed state, the bearing member 11 is rotatably connected to the stay 8 with a predetermined frictional resistance, while the flat portion 81 of the stay 88 is formed. Is in contact with the stay 8 with a predetermined holding force. As a result, the support portion 6 and the sun visor main body 5 are rotatably supported by the stay 8, and are positioned with a moderation at a predetermined rotation position.
[0013]
A reinforcing bar 12 extending downward is fixed to the bearing member 11. The reinforcing bar 12 is inserted into and adhered to a corrugated cardboard hole constituting the core 7A of the sunshade 7.
[0014]
A window hole 66A is formed at the other end of the upper part of the half body 6A. As shown in FIG. 3, a portion between the window hole 66A and the upper end of the half body 6A has a semicircular shape, and is formed by a portion between the window hole 66B and the upper end of the other half body 6B. A cylindrical section 66 having a circular cross section is formed. The cylindrical portion 66 is rotatably supported by the hook 9.
[0015]
In the sun visor for a vehicle having the above configuration, the sun visor main body 5 is divided into the support portion 6 and the sunshade portion 7. Therefore, the support portion 6 is shared by each sun visor main body 5 and the sunshade portion 7 is provided. Only need to be manufactured according to each sun visor body 5. In this case, since the bearing member 11 is not disposed on the sunshade portion 7, it can be easily manufactured even if the dimensions are different. On the other hand, the support portion 6 can be formed to have a constant shape and size even if the vehicle type is different, so as to be shared by the sun visor bodies 5. In addition, by making the shape and size of the support portion 6 constant, the bearing member 11 can be arranged at a fixed position of the support portion 6. Therefore, the support portion 6 can be mass-produced, and the production efficiency can be improved.
[0016]
When the entire sun visor main body 5 is integrally formed, the bearing member 11 is embedded in the cushion member 7B, so that the space for the bearing member 11 is reduced. As a result, the degree of freedom in designing the bearing member 11 is reduced, and it becomes difficult to adjust the magnitude of the rotational resistance force between the stay 8 and the bearing member 11. In this regard, in the sun visor according to the present invention, the bearing member 11 is disposed in the space 65 of the support portion 6, and the cushion member 7B is not disposed in the space 65. Therefore, the space for the bearing member 11 can be widened, whereby the adjustable range of the turning resistance of the bearing member 11 can be widened.
[0017]
Furthermore, since the sunshade 7 is not provided with the bearing member 11 and is made of only resin, the sunshade 7 can be easily reused.
[0018]
In the sun visor of this embodiment, the sunshade 7 is sandwiched and fixed by the pair of halves 6A and 6B. Therefore, the opening of the skin 7C of the sunshade 7 is made of a core material. After inserting the 7A and the cushion material 7B, there is no need to seal. Therefore, the labor required for manufacturing can be reduced by that much, and the manufacturing cost of the sun visor A can be reduced. In addition, the sealing of the open portion is usually performed by welding the skin 7C. However, when the welding is performed, burrs are generated and the appearance is impaired. By fixing and fixing the sunshade portion 7 as in this embodiment, it is possible to prevent such a problem from occurring and to eliminate the trouble of cutting off the burr.
[0019]
Further, various cards such as a parking ticket can be inserted between the half body 6A or the half body 6B and the sunshade part 7, and they can be used as a kind of card holder.
[0020]
The present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention.
For example, in the above-described embodiment, the support portion 6 is constituted by the pair of halves 6A and 6B, but may be integrally formed as a whole.
[0021]
【The invention's effect】
As described above, according to the vehicle sun visor of the present invention, the sun visor body is rotatably supported by the stay via the bearing member, and the support portion rotatably supported by the hook. Since the support portion is divided into a sunshade portion in which the upper portion is pinched and fixed, manufacturing costs can be reduced, and the adjustment range of the rotational resistance by the bearing member can be widened. The sunshade can be easily reused, and the fixing portion of the sunshade sandwiched by the pair of halves can be used as a kind of card holder, and a through hole is formed in the sunshade. However, by inserting the pair of half positioning protrusions into the through holes, an effect is obtained that the sunshade can be prevented from dropping off the support.
Further, the awning parts, core material, when the cushion material and these were therefore constructed in Tables skin that is inserted into the top opening, there is no need to close the welder working like a top opening of the skin, As a result, the manufacturing cost can be further reduced, the occurrence of burrs due to welding can be eliminated, and therefore, the aesthetic appearance can be improved, and the labor required for deburring can be reduced. Can be
Furthermore, since the upper and lower parts of the reinforcing bar are inserted into the support part and the shade part, respectively, and are fixed to the bearing member provided in the support part and the core material of the shade part, respectively. In the case where the sun visor body is rotated with the protection portion, it is possible to prevent the protection portion from being deformed at the portion where the support portion is sandwiched.
