Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to an auxiliary light-shielding sun visor that is provided at the edge of a sun visor body mounted on a vehicle so as to be able to protrude and retract.
[0002]
[Prior art]
For example, when driving a vehicle east in the early morning, when sunrise is encountered, sunlight enters from a low position on the front with a substantially horizontal direction or a slight vertical angle, making it very difficult for the driver to see the front . In addition, even during driving toward the west before sunset in the evening, the front becomes extremely difficult to see similarly due to the sunset.
[0003]
In such a case, if light is to be shielded by a totally light-blocking sun visor provided as a general equipment in a vehicle such as an automobile, the sun visor must be adjusted to substantially the same height as the eye level. Is greatly restricted, making driving very difficult.
[0004]
A similar phenomenon may occur when the headlights of a following vehicle at night are reflected on a rearview mirror or a side mirror.
[0005]
On the other hand, conventionally, many proposals have been made on an auxiliary sun visor in order to cope with such driving difficulties. For example, there is a known type in which a light-shielding plate having a low light transmittance is provided at a lower end portion of a general visor body as a general equipment described above in a vertical state so that the light-shielding plate can be pulled out in a vertical direction (Patent Documents 1 and 2). 2).
[0006]
Similarly, a light-shielding plate is mounted on the lower part of the sun visor so as to be able to undulate (patent document 3), or in addition to the function of being undulated, the light-shielding plate can be moved in the left-right direction along a guide provided horizontally below the sun visor (Patent Literature 4) and the like have also been proposed.
[0007]
In addition, as other similar techniques, Japanese Patent Application Laid-Open Nos. 10-203165, 2002-331833, and 2000-343944 have been proposed.

[Problems to be solved by the invention]
However, in the above-mentioned conventional auxiliary sun visor, it cannot be easily and stably attached to and detached from the sun visor main body, and a moving mechanism for allowing the light shielding plate to protrude and retract along the vertical direction, and In most cases, it is necessary to sequentially perform two-stage operations of vertical movement and horizontal movement for the movement of the light shielding plate in the inclined direction or the like.
[0013]
Therefore, there is a problem in that the oblique movement, the protruding movement, the positioning, and the like of the light shielding plate performed by each of these mechanisms are instantaneously performed during traveling. That is, it takes time to operate the light shielding plate in accordance with the change in the light shielding position, and fine adjustment of the light shielding plate position is troublesome.
[0014]
Furthermore, it is sufficient for an annular light source such as sunlight to accurately shield the enlarged circular area of a certain diameter from the center position, and at the same time as the light is shielded, the surrounding visual field is in a normal state. In contrast to the above, it is desirable to make it visible with the conventional technology, whereas in the related art, the surroundings are often hidden, and the visual field in the driving direction is often narrowed excessively.
[0015]
Also, in the conventional technology, the structure is complicated, such as adding a special stop mechanism to easily move and stop the light shielding plate, the number of parts is large, the production is troublesome, and the cost is low. Easy to get high.
[0016]
The present invention has been made in view of such circumstances, and can be easily attached to the sun visor body, and the light shielding plate can be freely moved by rotation following the change of the light shielding position, The light-shielding operation during traveling can be performed quickly and easily, fine adjustment of the light-shielding position can be performed well, and fixing of the light-shielding plate at the fixed position can be easily and reliably performed. Only the necessary area can be shielded from light, and the area outside the area can be easily viewed in a normal state, eliminating the possibility of narrowing the visual field in the driving direction, improving safety, and further improving the structure. It is an object of the present invention to provide an auxiliary sun visor which is simple, has a small number of parts, can be manufactured without any trouble, and can be manufactured at low cost.

[Embodiment of the invention]
Hereinafter, embodiments of the auxiliary sun visor according to the present invention will be described with reference to the drawings.
[0024]
1 to 3 show an embodiment of the present invention. FIG. 1 is a perspective view showing a state in which the auxiliary sun visor is mounted on the sun visor body, and FIG. 2 is an exploded perspective view of the auxiliary sun visor. FIG. 3 is a sectional view taken along line AA of FIG.
[0025]
As shown in FIG. 1, the auxiliary sun visor according to the present embodiment is attached to a sun visor main body 1 mounted on a vehicle, and has a disk shape, that is, a low light transmissive shape having a generally arc-shaped contour. The light shielding plate 2 includes a mounting member 3 for detachably mounting the light shielding plate 2 to the sun visor body 1.
[0026]
The diameter of the light shielding plate 2 is set to be substantially equal to the width of the sun visor body 1 in the height direction, and the periphery of the light shielding plate 2 can be pinched by a finger or the like. A mounting hole 4 is formed at one location near the periphery of the light shielding plate 2.
[0027]
On the other hand, the attachment 3 is configured as a U-shaped clip obtained by bending a strip-shaped elastic metal plate in the thickness direction, for example. The interval between the two pieces 3a and 4b of the mounting tool 3 as the clip is set slightly smaller than the thickness of the sun visor body 1, and for example, it can be sandwiched at an arbitrary lateral position from the lower side of the sun visor body 1 upward. I can do it. Note that a support hole 5 for mounting a shaft is formed in one piece 3a of the mounting tool 3 arranged in the vehicle compartment of the sun visor body 1. Further, the upper end of the other piece 3b of the mounting tool 3 arranged on the windshield side of the vehicle is slightly inclined outward so that it can be easily sandwiched when mounted on the sun visor body 1.
[0028]
As shown in FIG. 3, the support hole 5 formed in the piece 3a of the mounting tool 3 is formed as a tapered hole having a gradually decreasing diameter toward the outside.
[0029]
A flathead screw as a shaft 6 is inserted into the support hole 5 from the inner side of the clip, and a flathead screw head 6a is fixed to one piece 3a of the mounting tool 3 by, for example, welding.
[0030]
The shaft 6 mainly composed of a flat head screw protrudes toward the outer surface of the clip. That is, in a state where the mounting tool 3 is mounted on the sun visor main body 1, the shaft 6 projects in a direction perpendicular to the surface of the sun visor main body 1 in the thickness direction.
[0031]
The distal end side of the shaft 6 is inserted through an inner first washer 7, a spring washer 8 and an inner second washer 9 which are sequentially arranged on the outer surface of the piece 3a of the mounting tool 3, and the hole 4 of the light shielding plate 2 is located at the outer position. Has been passed through. That is, by inserting the shaft 6 into the hole 4, the light shielding plate 2 can rotate around the shaft 6.
[0032]
Further, the distal end side of the light shielding plate 2 on the shaft 6 is inserted through the first outer washer 10, the spring washer 11, and the second outer washer 12. Then, a pair of nuts 13 is screwed into the extreme end position of the shaft 6, thereby fastening with a double nut structure.
[0033]
With the fastening structure using these double nuts, fastening is performed in which an appropriate frictional force is generated with respect to the preset light shielding plate 2. Thus, the light-shielding plate 2 is rotatably supported on the mounting device 3 via the shaft 6 with a certain resistance or more, and rotatable only when a force exceeding the resistance is applied. Then, the arc-shaped contour portion of the light-shielding plate can be protruded and retracted from the edge of the sun visor main body 1 by rotating about the shaft 6.
[0034]
The light shielding plate 2 mounted on the sun visor main body 1 is made of a flat resin plate having a low light transmittance as described above, and the diameter thereof is set substantially equal to the vertical height of the sun visor main body. Thereby, the periphery of the light shielding plate 2 can be pinched by a finger or the like. As described later, the light-shielding plate 2 configured in a circular shape is used to protrude from the sun visor main body 1 in order to weaken the irradiation of sunlight or the like, so that the light-shielding plate 2 has a certain diameter from the center point of the sunlight or the like. It has a shape having a contour portion that shields light along.
[0035]
The sun visor body 1 is supported by a substantially L-shaped support arm 1a provided on the vehicle body. The support arm 2a rotates vertically about a horizontal shaft portion (up and down motion) and supports the support arm 2a. The arm 2a is configured to be able to rotate in the left and right directions around the longitudinal axis portion. Thus, the sun visor body 1 can change its posture between a non-use state in which the flat surface, which is a surface in the thickness direction, is along the vehicle body roof side, and a use state at the time of light blocking hanging down on the front side of the vehicle window. The light shielding plate 2 can take various postures together with the sun visor body 1.
[0036]
Next, the operation of the auxiliary sun visor according to the present embodiment having the above configuration will be described.
[0037]
During normal driving that does not require shading, the sun visor body 1 is kept in a state of being flipped up toward the vehicle roof. In this case, the light-shielding plate 2 is flipped up to the roof side of the sun visor body 1 and turned upward from the state of FIG. 1 to be substantially horizontal, and is placed on the upper surface side of the sun visor body 1. State. Therefore, when the light shielding plate 2 is not used, the light shielding plate 2 is securely held on the sun visor main body 1 and does not move at all.
[0038]
On the other hand, when light shielding is required, the sun visor main body 1 is suspended downward and forward with the support shaft 1a as a center, so as to be in the vertical state shown in FIG. In this state, since the light shielding plate 2 is located on the side surface of the sun visor main body 1, the peripheral edge of the light shielding plate 2 can be picked up with a finger and the light shielding plate 2 can be rotated about the shaft 6 in the vertical direction or the like.
[0039]
This turning operation can be easily performed simply by turning with a force exceeding the fixing force of the spring washers 8 and 11 for holding the light shielding plate 2 to the mounting device 3 with an elastic pressing force, and can be freely performed. The projecting position of the light shielding plate 2 can be set. Further, after the light shielding plate 2 is set at a predetermined rotation position, by releasing the hand, the light shielding plate 2 can be fixedly held by the pressing force of the spring washers 8 and 11, and the angle adjustment by rotation can be easily performed. And it can be performed reliably.
[0040]
When the light-shielding plate 2 is adjusted to a position where sunlight or the like enters from the viewpoint of a driver or the like, the light-shielding plate 2 is circular and blocks light along a range of a certain diameter from the center point of the sunlight or the like. Since the shape has a contour portion to be performed, a dazzling range centered on one point of a light source such as the sun is uniformly covered in the circumferential direction.
[0041]
Therefore, by appropriately adjusting the extraction angle and the amount by the rotation of the light shielding plate 2, the field of view in a normal state can be obtained from other portions than the circular light shielding plate 2 by extracting the light transmission range to a predetermined range. For example, even when the sun and the like and the traffic signal lamp and the like seem to be close to each other, it is easy to make fine adjustments to the position. As a result, driving comfort, safety, and the like can be greatly improved as compared with the related art.
[0042]
As described above, according to the present embodiment, the light-shielding plate 2 can be freely moved in the left-right direction or the like by rotating the light-shielding plate 2 so as to follow the change in the light-shielding position, and the operation during traveling can be easily performed. .
[0043]
In addition, fine adjustment of the position of the light shielding plate 2 can be performed quickly and satisfactorily, and the fixed position can be reliably fixed. In addition, only a certain necessary range around the light source can be shielded from light, and the surrounding area is easy to see in a normal state, and it is possible to eliminate the narrowing of the visual field in the driving direction, thereby improving safety.
[0044]
Further, in the present embodiment, the configuration is relatively simple including the mounting tool 3, the circular light shielding plate 2, the shaft 6, and the like, the number of parts is small, the production is not troublesome, and the cost is reduced. Promotion is also possible.
[0045]
FIG. 4 is an explanatory view showing another embodiment of the present invention.
[0046]
In the embodiment shown in FIG. 4, instead of the double nut structure of the above-described embodiment, the cap nut 14 is screwed to the tip of the shaft 6 made of a countersunk screw. When the cap nut 14 is applied, the fastening is completed at a position where the tip of the shaft 6 comes into contact with the inner end of the hole of the cap nut 14, so that the length of the shaft 6 and the length of the hole of the cap nut 14 are determined in advance. Is set, the light-shield plate 2 is always fastened in a state where an appropriate frictional force is generated when the worker performs assembling, so that the work can be easily performed. Moreover, since the fastening force of the light-shielding plate is uniformly determined, the quality as a product can be provided as being constant. As a result, it is possible for the user to obtain an advantage that high-quality products are stably supplied.
[0047]
In the above embodiment, the light-shielding plate 2 is circular. However, the present invention is not limited to this, and in addition, an elliptical shape, an elliptical shape, a polished shape, a polygon with rounded corners, or a distorted shape thereof It can be implemented as a shape or the like. In short, the light-shielding plate 2 only needs to have a shape having a contour that shields light along a range of a certain diameter from the center point of sunlight or the like when used to reduce sunlight irradiation or the like.
[0048]
Further, in the above-described embodiment, the position where the light-shielding plate 2 is supported by the shaft 6 is set as the peripheral portion. However, this is for the most efficient use of the light-shielding plate 2 having a predetermined diameter. It may be arranged in the vicinity slightly separated from the peripheral position.
[0049]
[Effect of the invention]
According to the auxiliary sun visor according to the present invention, the sun visor can be easily attached to the sun visor body, the light shielding plate can be rotated by following the change in the light shielding position, and the operation during traveling can be easily performed, The position can be finely adjusted quickly and satisfactorily, it can be fixed in a fixed position reliably, and it can shield only a certain necessary area around the light source. In addition, it is possible to improve safety by eliminating the narrowing of the field of view, and to achieve excellent effects such as a relatively simple configuration, a small number of parts, and a reduction in manufacturing cost and cost.
