Description

[Detailed description of the invention] <<Field of invention>> This invention relates to a sun visor for automobiles, and is of a type in which the side edges are bent when the sun visor is retracted, and is particularly excellent in operability, durability, and design. This invention relates to sun visors for automobiles.

《Prior art and its problems》 Usually, a sun visor is installed above the front window of a car to block sunlight.
This is to ensure the driver's visibility while driving.

This sun visor is attached to the ceiling via a support shaft, rotates around this support shaft, and is positioned so that it is almost parallel to the front window when in use, and is stored along the ceiling when stored. There is.

However, the inner surface of the ceiling is usually formed in a curved shape, especially on the sides, and if a flat sun visor is housed in this curved inner surface of the ceiling, it will give a sense of discomfort to the occupants, and the inner surface of the ceiling and the sun visor will be disconnected. A large gap was created between the two, creating a problem in terms of effective use of space.

For this reason, a type of sun visor has been proposed in which the side end portions are bent into a curved shape along the shape of the inner surface of the ceiling, as shown in FIGS. 5 and 6.

First, a predetermined bending line 2 is set for the sun visor 1, and the sun visor main body 3 and the side end portions 4 are divided using this bending line 2 as a boundary. Almost flat reinforcing plates 5 and 6 are buried inside, and by giving flexibility to the bending line 2, it functions as a hinge part 7, and when the sun visor 1 is retracted, the side end part 4 is It is bent to fit the curved shape of the ceiling.

Therefore, as shown in FIG.
When stored, the sun visor body 3 and side edges 4
A force is applied from the ceiling surface 8 in the direction of the arrow, and as a result, the side end portion 4 bends along the hinge portion 7 with respect to the sun visor body 3.

However, in the case of such a folding type sun visor 1, in order to make the sun visor 1 fit into the ceiling surface 8, it is necessary to maintain the sun visor in its retracted state, that is, in a state in which an external force is applied from the ceiling surface 8 to the sun visor side. Therefore, it is necessary to set a large rotational torque value of the shaft 9 for one rotation of the sun visor.

If the rotational torque value of the shaft 9 is set to a large value in this manner, a large operating force is required when rotating the sun visor 1 with respect to the shaft 9, and a smooth rotational operation cannot be expected. Further, since such a large rotational torque is provided, there are disadvantages such as being a factor in reducing the durability of the shaft 9 holding mechanism itself.

In addition, a thin hinge portion 7 is formed between the sun visor body 3 and the side end portion 4, which is undesirable from an aesthetic point of view. Although the hinge portion 7 needs to have an appropriate degree of rigidity to maintain its position, long-term use weakens the shape retention of the hinge portion 7, and the side end portions 4 easily bend even when the sun visor is used. It was also pointed out that it was not easy to use.

《Purpose of the invention》 This invention was made in view of the above-mentioned circumstances, and the purpose of the invention is to provide a sun visor whose lateral ends are bendable with respect to the sun visor body, so that it fits on the curved surface of the ceiling. This is a sun visor that is stored along the side of the sun visor, and the rotational torque value of the rotating shaft that holds the sun visor can be set to a low value, which improves operability, improves the durability of the shaft holding mechanism, and also improves the appearance. It is an object of the present invention to provide a sun visor for an automobile that is easy to use and convenient.

《Structure and Effects of the Invention》 In order to achieve the above object, the present invention provides a type in which when the sun visor is retracted, the lateral end portion can be bent freely with respect to the sun visor body, and the sun visor is retracted along the curved shape of the ceiling. The sun visor includes reinforcing plates embedded in the sun visor main body and side ends, and a return type leaf spring fixed in a bridge-like manner between the reinforcing plates, and the return type leaf spring is used in the sun visor. When the sun visor is retracted, it maintains a flat shape, and when the sun visor is retracted, it maintains a bent shape with a roughly doglegged cross section.
The present invention is characterized in that each of the above shapes is alternately reversed.

In other words, regarding the sun visor according to the present invention,
The reinforcing plates embedded in the sun visor body and side edges are connected by returnable leaf springs, and the returnable leaf springs are alternately reversed to form a flat shape and a bent shape. When the sun visor is stored, it is in a folded state, and unlike conventional methods, the side edges of the sun visor are not forcibly bent with respect to the sun visor body due to external force from the ceiling surface, so the rotation that holds the sun visor is The rotational torque value of the shaft can be set to a small value, the durability of the holding mechanism of this rotating shaft can be significantly improved, and in addition, the rotation operation of the sun visor that rotates around the shaft can be performed smoothly. There is.

In addition, in the case of the present application, since only a return type leaf spring is built in between the sun visor body and the side ends, it has a simple structure, can be manufactured at low cost, and has an appearance that is no different from a conventional flat sun visor. The design remains the same and is more aesthetically pleasing than a sun visor with a hinge.

Furthermore, since it is a return type leaf spring, it alternately inverts to take two shapes, a flat state and a roughly doglegged state, and maintains that shape, so when using a sun visor, it can be Unlike a sun visor, the side edges do not retain their shape, so the operability is not degraded and the usability is also favorable.

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

Fig. 1 is a partially cutaway front view showing the sun visor for an automobile according to the present invention in use, Fig. 2 is a partially cutaway perspective view showing the sun visor in a retracted state, and Fig. 3 is a sun visor used in the sun visor according to the present invention. FIG. 4 is a perspective view showing a return type leaf spring, and FIG. 4 is a sectional view illustrating the sun visor according to the present invention when it is in use and when it is stored.

In FIG. 1, a sun visor 10 according to the present application
The outer periphery of the wire core frame 11 bent into a loop shape is covered with a pad material 12 such as urethane foam and the like.
The wire core frame 11 is covered with a skin material 13 such as a PVC sheet, and a support 14 made of resin is press-fitted into the wire core frame 11, and one end of the shaft 15 is inserted into the support 14.
The other end of this shaft 15 is connected to the vehicle body (not shown).
It is rotatably inserted into a bracket 16 fixed to.

Therefore, the sun visor 10 is configured to be able to rotate vertically about the shaft 15, and the shaft 15 is also configured to be able to rotate horizontally relative to the bracket 16.

Furthermore, regarding the sun visor 10 according to the present application,
A side end portion 18 is configured to be bendable with respect to the sun visor body 17.

To explain this configuration in detail, first, inside the sun visor body 17 and the side end portion 18, there are reinforcing plates 19 made of cardboard, fiberboard, etc., respectively.
20 are buried respectively, and a return type leaf spring 21 is installed as a bridge to both of these reinforcing plates 19 and 20.
is fixed by adhesive or mechanical fastening.

The return type leaf spring 21 is formed by opening a pair of parallel slits 22, 22 at a predetermined interval, and bending the portion sandwiched between the slits 22, 22 into a substantially dogleg shape. Return type leaf spring 21
As shown in FIG. 3, it can be alternately reversed into a flat shape (FIG. 3a) and a bent shape having a substantially doglegged cross section (FIG. 3b).

Therefore, the sun visor 10 of the present invention is attached to the shaft 1.
When rotated upward 5 times and placed in the retracted state,
The side end portion 18 comes into contact with the curved surface of the ceiling, the roof side, etc., and the return type leaf spring 21 enters the bent state shown in FIG. 3b and maintains this bent shape. As a result, the sun visor 10 has a lateral end 18 relative to the sun visor body 17, as shown in FIGS. 2 and 4b.
maintains a state bent at a predetermined angle.

And when using a sun visor, sun visor 10
If the side end portion 18 is corrected so that it is flush with the sun visor body 17 by rotating it downward around the shaft 15, the return type leaf spring 21 becomes almost flat as shown in Fig. 3a. As a result, the sun visor 10 is held in a flat state so that the sun visor body 17 and the side ends 18 are located substantially on the same top, as shown in FIG. 4a.
Good light shielding performance can be obtained.

As described above, the sun visor 10 according to the present application has a built-in reversible return type leaf spring 21, and the side end portion 18 can be arbitrarily bent regardless of the rotational torque value of the rotating shaft 15.
This is an extremely practical idea, as it improves operability when rotating, increases the durability of the shaft holding mechanism, and also has a good appearance and improved usability.
