Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sun visor device provided in a vehicle or the like, and more particularly, to a sun visor device that is excellent in shielding light from sunlight incident from a low position and that is improved in operability and the like.
[0002]
[Prior art]
For example, when driving the vehicle eastward in the early morning, when it encounters sunrise, sunlight enters from a low position on the front surface in a substantially horizontal direction or at a slight vertical angle, making it 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 due to the sunset.
[0003]
In such a case, if an attempt is made to shield light by using a light-shielding sun visor provided as a general equipment in a vehicle such as an automobile, the sun visor must be adjusted to approximately the same height as the eye level. Will be severely restricted, making it very difficult to drive.
[0004]
The same phenomenon may occur when the headlight of the following vehicle at night reflects on the rearview mirror or side mirror.
[0005]
On the other hand, conventionally, many proposals have been made for sun visor devices in order to cope with such driving difficulties. For example, there is known a low-light-transmitting light-shielding plate that can be pulled out in the vertical direction at the lower end when the sun visor as a general equipment is in a vertical state (Patent Documents 1 and 2). ).
[0006]
Similarly, a shading plate is mounted on the lower part of the sun visor so that it can be raised and lowered (Patent Document 3), or in addition to the function of raising and lowering, the shading plate can be moved left and right along a guide provided horizontally on the lower part of the sun visor (Patent Document 4) etc. are also proposed.
[0007]
In addition, as other similar techniques, Japanese Patent Laid-Open Nos. 10-203165, 2002-331833, 2000-343944, and the like have also been proposed.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a sun visor device according to the present invention will be described with reference to the drawings.
[0025]
1 to 3 show an embodiment of the present invention. FIG. 1 is a perspective view showing the overall configuration of the sun visor device, and FIG. 2 is a cross-sectional view taken along line AA of FIG. FIG. 3 is an operation explanatory diagram.
[0026]
As shown in FIG. 1, a sun visor device 1 of the present embodiment is integrated with an all-light-shielding plate-like sun visor base 2 (refer to a virtual line) as general equipment provided at the upper front position inside a vehicle such as an automobile. It is comprised, or it is comprised so that attachment or detachment is possible as a separate body. In the case of a detachable configuration, for example, it is configured to be mounted on the outer surface of the sun visor base 2 via a clip, bolt, band, or other detachable tool (not shown). These configurations can be arbitrarily selected, and any configuration can be applied to a new vehicle or an existing vehicle, respectively.
[0027]
The sun visor base 2 is supported by a substantially L-shaped turning support arm 2a provided on the vehicle body. The sun visor base 2 is turned up and down around the horizontal axis portion of the support arm 2a. The arm 2a is configured to be capable of rotating in the left-right direction around the longitudinal axis of the arm 2a. As a result, the sun visor base 2 can change its posture between a non-use state in which the flat surface, which is the surface in the plate thickness direction, extends along the vehicle body roof side, and a use state during light shielding where it hangs down to the front side of the vehicle window.
[0028]
The sun visor device 1 of the present embodiment can take various postures together with the sun visor base 2 described above. In the following description, “up and down”, “left and right”, and the like are described with a basic posture being a use state when the sun visor base 2 is suspended downward from the support arm 2a. In the following description, “front” indicates the front side of the vehicle, and “rear” indicates the rear side of the vehicle.
[0029]
As shown in FIGS. 1 and 2, the sun visor device 1 includes a pair of parallel support plates (front support plate 3, rear support plate 4) facing front and rear with a narrow gap, and these support plates 3, 4. And a light shielding plate 6 inserted in the gap 5. The front support plate 3 has slightly larger vertical and left and right dimensions than the rear support plate 4. Each of the support plates 3 and 4 may be configured as a single body by resin shaping, or may be configured by winding a cloth or other various wall forming materials around a metal frame, although not illustrated, It can be made of a material.
[0030]
Each support plate 3, 4 has a horizontally long rectangular shape, and the upper end edges (one end in the short direction) of these support plates 3, 4 are connected to each other via a connecting portion 7. The other three edge portions of each support plate 3, 4, that is, the lower edge portion that is the other end portion in the short direction, and the both left and right edge portions that are both end portions in the longitudinal direction have a non-connected structure. Thereby, the lower end opening 8 and the left and right openings 9, 10 are formed.
[0031]
At the peripheral positions of the openings 8, 9, 10 of the front support plate 3, folded portions 11, 12, 13 projecting in the plate thickness direction (rear) are formed. As shown in FIG. 2, these folded portions 11, 12, and 13 are disposed slightly behind the inner surface of the front support plate 3 and ahead of the inner surface of the rear support plate 4. As a result, openings 8, 9, and 10 communicating with the internal gap 5 are formed in the downward and left-right directions at the lower ends and the left and right peripheral positions of the front support plate 13 and the rear support plate 4, respectively. A magnetic metal plate 14 is integrally incorporated on the inner surface of the front support plate 3 over substantially the whole. The magnetic metal plate 14 may be provided on the inner surface of the rear support plate 4 or may be provided on the inner surfaces of both support plates 3 and 4.
[0032]
The light shielding plate 6 is inserted into the gap between the support plates 3 and 4. The light shielding plate 6 includes, for example, a circular light shielding plate main body 15 and a shaft portion 16 provided on the main body.
[0033]
The light shielding plate main body 15 is made of, for example, a flat resin plate material with low translucency, and its diameter D is set to be slightly larger than the vertical height H of the support plate. Thereby, in the state where the light shielding plate main body 15 is inserted into the support plates 3 and 4, at least the lower end portion slightly protrudes from the opening 8 on the lower end side of the support plates 3 and 4, and this portion can be picked with a finger or the like. It can be done. The light shielding plate main body 15 is slidable in all directions along the plate surfaces of the support plates 3 and 4. As described later, the light shielding plate body 15 configured in a circular shape has a constant diameter from the center point of sunlight or the like when used by being pulled out from the support plates 3 and 4 in order to weaken irradiation of sunlight or the like. The shape has a contour portion that shields light along the range.
[0034]
The shaft portion 16 is made of a permanent magnet body that protrudes in a shaft shape from the front outer circumferential position, which is one point of the plate surface of the light shielding plate body 15, and the protruding tip portion 16b has a larger diameter than the base end portion 16a. It is comprised as a different diameter cylindrical body. The shaft portion 16 made of the permanent magnet body is always in contact with the magnetic metal plate 14 provided in the support plates 3 and 4 and is attracted by the attractive force, thereby applying a certain force to the light shielding plate body 15. It is possible to move along the plate surfaces of the support plates 3 and 4 together with the light shielding plate main body 15 only in the case.
[0035]
The shaft portion 16 is attracted and fixed to the magnetic metal plate 14 by an attractive force when a certain amount of moving force is not applied to the light shielding plate body 15. In this state, when turning force is applied to the light shielding plate main body 15, the light shielding plate main body 15 can rotate about the shaft portion 16. In addition, the thickness of the protruding end side of the shaft portion 16 is set so that it can be inserted into the folded portions of the holding frames 11, 12, 13 provided in the openings 8, 9, 10 of the support plates 3, 4. .
[0036]
That is, in the present embodiment, the shaft portion 16 is constituted by a permanent magnet, while the magnetic metal plate 14 is provided on the inner surface of the support plate, and the magnetic attraction force generated between them becomes the movement resistance force of the shaft portion 16. The light shielding plate 6 can be fixedly held at each position along the plate surfaces of the support plates 3 and 4. As a result, the shaft portion 16 has two functions as a rotation fulcrum and a stopper function. That is, in a range where the shaft portion 16 is locked to the holding frames 11, 12, and 13, a part or substantially the whole of the light shielding plate main body 15 can be pulled out to the outer periphery of the holding frames 11, 12, and 13. In addition, movement along the plate surfaces of the support plates 3 and 4 and rotation around the shaft portion 16 are possible.
[0037]
Next, the operation of the sun visor device according to the present embodiment having the above configuration will be described.
[0038]
During normal driving that does not require light shielding, the sun visor base 2 is kept in a state of being flipped up to the vehicle roof side. In this case, the lower end edge of the support plates 3 and 4 into which the light shielding plate 6 is inserted jumps to the roof side of the sun visor base 2 and turns upward from the state of FIG. The openings 8, 9, and 10 for taking in and out are located on the upper side, and the light shielding plate 6 is securely held in the support plates 3 and 4 and is not moved at all.
[0039]
On the other hand, when it is necessary to shield the light, the sun visor base 2 is suspended downward from the support shaft 2a as shown in FIG. In this state, the opening 8 at the lower edge of the support plates 3 and 4 opens downward. Here, in this embodiment, the diameter D of the light shielding plate 6 is set to be slightly larger than the height H of the support plates 3 and 4, and a part of the periphery of the light shielding plate 6 is an opening of the support plates 3 and 4. By projecting downward from 8, the projecting portion of the light shielding plate 6 can be picked up with a finger, and can be slid vertically or diagonally downward, or moved in the horizontal direction. . Further, as shown in FIG. 3, the support plates 3 and 4 are lifted along the openings 9 and 10 at the left and right edge portions, and the light shielding plate 6 is rotated in the vertical direction and so on using the shaft portion 16 as a fulcrum. It can also be made.
[0040]
Such a sliding operation can be easily performed only by giving a moving force that resists the attractive force of the shaft portion 16 made of a permanent magnet to the magnetic metal plate 14 disposed in the support plates 3 and 4. It can be set freely. As for the rotation of the light shielding plate 6, the shaft portion 16 can be attracted to the magnetic metal plate 14 by a constant absorption force by a magnetic force, and can be sufficiently held as a fulcrum for rotation. Angle adjustment and the like can be easily and reliably performed under the fixed shaft portion 16.
[0041]
In addition, when the light shielding plate 6 is pulled out, the shaft portion 16 abuts on the holding frames 11, 12, 13 provided on the peripheral edges of the support plates 3 and 4 as a stopper, so that the dropping can be reliably held. In particular, in the present embodiment, the shaft portion 16 includes a proximal end portion 16a having a small diameter and a distal end portion 16b having a large diameter, while the holding frames 11, 12, and 13 are folded back in the thickness direction of the support plates 3 and 4. By forming the large-diameter portion 16a of the shaft portion 16 inside, the light shielding plate 6 can be reliably prevented from falling off.
[0042]
When the light shielding plate 6 is aligned with a position where sunlight or the like enters from the viewpoint of the driver or the like, the light shielding plate 6 is circular and shields light from a central point of sunlight or the like along a certain diameter range. 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.
[0043]
Therefore, the field of view in the normal state can be secured from other parts than the circular light shielding plate 6 by appropriately adjusting the amount of drawing of the light shielding plate 6 and drawing out to a range where the predetermined light transmittance reducing effect is reached. For example, even when sunlight and traffic light lamps appear close to each other, it is possible to adjust the position easily. The comfort, safety, etc. can be greatly improved as compared with the prior art.
[0044]
Thus, according to the present embodiment, the light shielding plate 6 can be moved freely in an oblique direction or the like following the change in the light shielding position, and an operation during traveling can be easily performed.
[0045]
Further, the fine adjustment of the position of the light shielding plate 6 can be performed quickly and satisfactorily, and the fixed position can be surely fixed.
[0046]
In addition, only a certain necessary range around the light source can be shielded, the surroundings are easy to see in a normal state, and the field of view in the driving direction can be eliminated to improve safety.
[0047]
Furthermore, in the present embodiment, the comparison is made of the support plates 3 and 4, the circular light shielding plate 6 and the shaft portion 16 made of permanent magnets provided thereon, the magnetic metal 14 plate provided in the support plates 3 and 4, and the like. It is simple, has a small number of parts, does not require much time for production, and can promote cost reduction.
[0048]
FIG. 4 is an explanatory view showing another embodiment of the present invention.
[0049]
In the embodiment shown in FIG. 4, the shape of the support plates 3 and 4 is curved at both corners of the upper side, and the shape of the light-shielding plate 6 is circular and the neck portion is provided. For example, it is configured in a bent bowl shape.
[0050]
That is, according to the present embodiment, the length between the shaft portion 16 and the edge portion of the light shielding plate 6 located on the opposite side of the shaft portion 16 so that the light shielding plate 6 can protrude greatly during use. L is larger than the height H of the support plate. As shown by phantom lines in FIG. 4, the light shielding plate 6 can be protruded greatly from the support plates 3 and 4 when in use, while the light shielding plate 6 is rotated horizontally when not in use. By storing in 3 and 4, the amount of projection of the light shielding plate 6 from the support plates 3 and 4 when not in use can be maintained substantially the same as in the first embodiment.
[0051]
By adopting such a configuration, almost the entire circular portion of the light shielding plate 6 can be exposed to the outside. Therefore, when the sunlight is reduced, for example, it is always at the center position of the circular portion of the light shielding plate 6. A good field of view can be continuously secured by positioning the sunlight. In this case, also in this embodiment, as in the above-described embodiment, the support plate can be pulled out in any direction with a fixing force such as a magnetic force between the support plates, and can be stably fixed and held at an appropriate place. That is, it is possible to ensure sufficient convenience in use.
[0052]
In each of the embodiments described above, the entire shaft portion 16 is constituted by a permanent magnet. However, a part of the shaft portion 16 is provided within a range in which a sufficient suction holding force for the support plates 3 and 4 of the shielding plate 6 can be obtained. Only a permanent magnet may be used.
[0053]
In each of the above embodiments, the magnetic force is used as a means for obtaining the movement resistance force of the shaft portion 16, but the present invention is not limited to this, and various modifications are possible. For example, by using a spring force, a movement resistance means other than the magnetic force is used, such as a means that allows the shaft portion 16 to move into the support plates 3 and 4 and to exhibit a sufficient holding force when fixed. It can also be used.
[0054]
Moreover, in the said embodiment, although the axial part 16 was arrange | positioned in the peripheral position of the light-shielding plate main body 15, this is for using the light-shielding plate 6 of a predetermined diameter most efficiently, and is not necessarily restricted to this, A light-shielding body main body. You may arrange | position in the vicinity slightly spaced from 15 peripheral positions.
[0055]
In the above embodiment, the light shielding plate main body 15 has a circular shape (first embodiment) or a distorted bowl shape (second embodiment). However, the present invention is not limited to this. It can be implemented as an oval shape, a polished shape, a polygon with rounded corners, or a shape in which these are distorted. In short, the light shielding plate main body 15 has a shape having a contour portion that shields light from a central point of sunlight or the like along a range of a certain diameter when used by being pulled out from the support plate 6 in order to weaken sunlight irradiation or the like. It only has to be done.
[0056]
Further, in the above embodiment, the shaft portion 16 of the light shielding plate 6 has a step with a large diameter on the tip side , and the large-diameter tip portion of the shaft portion 16 is received, so that the peripheral position of the support plate is prevented from falling off. The holding frames 11, 12, and 13 are formed with folded portions, but this shows an example in which the shaft portion 16 is most effectively prevented from falling off, and various modifications are possible. is there. For example, the shaft portion 16 may have a constant diameter, and the drop-off prevention holding frames 11, 12, and 13 may be configured to be stepped portions that protrude in the thickness direction at the opening peripheral positions of the support plates 3 and 4.
[0057]
【The invention's effect】
According to the present invention, the light shielding plate can be moved freely in an oblique direction following the change of the light shielding position, and the operation during traveling can be easily performed, and the fine adjustment of the position can be performed quickly and satisfactorily, It can be securely fixed in a fixed position, and it can shield only a certain necessary range around the light source, and the surroundings are easy to see in the normal state, eliminating the narrowing of the field of view in the driving direction and safety In addition, it is possible to improve the performance, and further, the structure is relatively simple, the number of parts is small, the production is not troublesome, and the cost can be reduced.
