Further, according to the sun visor 1 for automobile of the present embodiment, it is possible to achieve optionally the sliding adjustment in the front-back direction, the angle adjusting in the front-back direction, and the angle adjusting in the crosswise direction within a given range in response to the angle of entering light and the position of driver's eyes to realize the shielding of light more exactly, and thus, safe and convenient driving circumstance can be provided.

[0045] By referring FIG. 1, the configuration of the sun visor 1 for automobile according to the present embodiment is explained. FIG. 1 is a perspective view for explaining the configuration of the sun visor 1 for automobile according to the present embodiment.

[0046] As shown in FIG. 1, the sun visor 1 for automobile of the present embodiment comprises a clip part 3 which clips a sun visor (light shielding plate) which is previously provided in a car usually, an almost plate-like first screen 9 having shielding property, a second screen 11 which is connected to the first screen 9 and has different shielding property (degree of shielding), a hinge part 5 and a joint part 7 which connect the clip part 3 to the first screen 9. The shielding properties (degrees of shielding) of the first screen 9 and the second screen 11 may be the same or different. For example, for a driver who feels a light entered from a space where the first screen 9 cannot shield so bright, it is preferable that the shielding property (degree of shielding) of the second screen 11 is made high.

<Configuration of Clip Part 3>

[0047] Next, by referring FIGS. 2A, 2B, and 2C, the configuration of the clip part 3 is explained in detail. FIGS. 2A, 2B, and 2C are views for explaining the configuration of the clip part 3.

[0049] As shown in FIG. 2B, the folded part 3B has a configuration where a bended part 15 is separated furthest from the smooth part 3A and a top edge 17 is closed nearest thereto. A part of the top edge 17 is bended outside (in the opposite direction to the smooth part 3A), and thereby the light shielding plate can be easily inserted between the smooth part 3A and the folded part 3B.

[0050] Further, a plurality of projections 13 are provided on the both opposed surfaces of the smooth part 3A and the folded part 3B, and, when clipping the light shielding plate, the projections 13 can grip the light shielding plate from upper and lower sides to improve the gripping force of the clip part 3. The shape and size of the projections 13 may be the same, or may be different depending to the position, or the like.

[0051] As shown in FIG. 2C, on the rear side of the surface of the smooth part 3A which is opposite to the folded part 3B, a first sliding rail 19 is provided. The first sliding rail 19 is formed almost parallel to the longitudinal direction of the smooth part 3A between the position near the bending part 15 and a top edge 23 (21), and connected to the hinge part 5 as explained below.

[0052] Furthermore, it is desirable that the clip part 3 is improved in safety and weight reduction by subjecting to chamfering treatment of convex corners (edges) and to thinning treatment depending to strength of the material to be used.

<Configuration of Hinge Part 5>

[0053] Next, by referring FIGS. 3A, 3B, and 3C, the configuration of the hinge part 5 is explained in detail. FIGS. 3A, 3B, and 3C are views for explaining the configuration of the hinge part 5. FIG. 3A is a front view of the hinge part 5, FIG. 3B is a side view of the hinge part 5, and FIG. 3C is a plan view of the hinge part 5.

[0057] The rotary part 5A and the sliding part 5B are connected so as to rotate (angle-adjust) freely in the manner that both connecting surfaces of the first connecting part 23 of the rotary part 5A and the second connecting part 25 of the sliding part 5B are concentric. Further, on the both connecting surfaces of the first connecting part 23 and the second connecting part 25, there are formed gears 35 where gears are formed radially from the center, and thus, it is possible to rotate stepwise the first connecting part 23 and the second connecting part 25 depending to the formed pitches of the gear 35. Namely, since the rotary part 5A and the sliding part 5B can be fixed at a desired point by an optional rotation angle by varying the formed pitch of the gear 35, angle adjusting of the parts can be simply achieved.

[0058] The third connecting part 27 of the rotary part 5A also has a gear 35 in the same manner as in the first connecting part 23 and the second connecting part 25.

<Configuration of Joint Part 7>

[0060] As shown in FIGS. 4A, 4B, and 4C, the joint part 7 is configured almost by a forth connecting part 28 which is connected to the third connecting part 27 of the rotary part 5A and a second rail clipping part 33 which is connected to the first screen 9 mentioned below.

[0061] The forth connecting part 28 is arranged so that, at almost the center of the joint part 7, two connecting surfaces are faced to each other while their centers are concentric, and the second rail clipping part 33 is engaged so as to be able to slide along a second sliding rail 20 of the first screen 9 mentioned below.

[0062] The joint part 7 and the rotary part 5A are connected so as to rotate (angle-adjust) freely by covering the forth connecting part 28 of the joint part 7 with the third connecting part 27 of the rotary part 5A from outside so that the centers of the both connecting parts are concentric. Further, since the connecting surface of the forth connecting part 28 has a gear 35 in the same manner as in the first, second and third connecting parts, the connecting angle between the joint part 7 and the rotary part 5A can be adjusted stepwise.

<Configuration of First Screen 9>

[0063] Next, by referring FIGS. 5A and 5B, the configuration of the first screen 9 is explained in detail. FIGS. 5A and 5B are views for explaining the configuration of the first screen 9. FIG. 5A is a front view of the first screen 9, and FIG. 5B is a side view of the first screen 9.

2. Method for Using Sun Visor 1 for Automobile

<Sliding Function and Angle-Adjusting Function by Sun Visor 1 for Automobile>

[0073] Next, by referring FIG. 7A to FIG. 9, the sliding function and the angle adjusting function which are provided in the sun visor 1 for automobile of the present embodiment are explained. FIGS. 7A and 7B are views for explaining the sliding function and the angle adjusting function in the front-back direction which are provided in the sun visor 1 for automobile of the present embodiment. FIG. 7A is a schematic view showing the sliding function in the front-back direction, and FIG. 7B is a schematic view showing the angle adjusting function in the front-back direction.

[0074] Further, FIG. 8 is a schematic view showing the angle adjusting function in the crosswise direction which is provided in the sun visor 1 for automobile of the present embodiment.

[0075] Furthermore, FIG. 9 is a schematic view showing the angle adjusting function in the front-back direction of the second screen 11.

[0076] As mentioned above, the sun visor 1 for automobile has a plurality of sliding function and angle adjusting function for realizing the optimum light shielding in response to the light entering position and angle of lights such as sunlight. Firstly, as shown in FIG. 7A, the first screen 9 and the second screen 11 can be slid in the front-back direction by engaging the clip part 3 and the hinge part 5 to adjust the position. More specifically, since the first sliding rail 19 of the smooth part 3B of the clip part 3 and the sliding part 5B of the hinge part 5 are engaged slidably, the position of the sliding part 5B can be optionally fixed within the movable distance corresponding to the length of the first sliding rail 19.

[0077] Further, as shown in FIG. 7B, by changing the relation of connection between the first connecting part 23 of the rotary part 5A and the second connecting part 25 of the sliding part 5B, the angle in the front-back direction between the first screen 9 and the second screen 11 can be adjusted within a given angle range around the center where the first connecting part 23 and the second connecting part 25 are connected.

[0078] Furthermore, as shown in FIG. 8, by changing the relation of connection between the third connecting part 27 of the rotary part 5A and the forth connecting part 28 of the joint part 7, the angle in the crosswise direction between the first screen 9 and the second screen 11 can be adjusted within a given angle range around the center where the third connecting part 27 and the forth connecting part 28 are connected.

[0079] As shown in FIG. 9, by changing the relation of connection between the fifth connecting part 29 of the first screen 9 and the sixth connecting part 30 of the second screen 11, the angle in the front-back direction between the first screen 9 and the second screen 11 can be adjusted within a given angle range around the center where the fifth connecting part 29 and the sixth connecting part 30 are connected.

[0080] Since the distance and angle arrangement between the driver's eyes and the first screen 9 and second screen 11 can be adjusted sensitively by using a plurality of the aforementioned sliding function and angel adjusting function, it is possible to arrange the first screen 9 and the second screen 11 to the optimum position and angle by adjusting in response to the position and entering angle of light. Further, in case that the second screen 11 is provided, when entering a strong light which cannot be protected by using the first screen 9 alone, the shielding efficiency can be improved by laminating the both, and, for example, when a light enters through a space formed between the upper side of the first screen 9 and the lower side of the clip part 3 to prevent the driver's field of view or the like, it is possible to shield the light which enters through the space by moving the second screen 11 in the front direction, while keeping the arrangement of the first screen 9.

[0081] As mentioned above, since the sun visor 1 for automobile of the present embodiment has a plurality of the sliding function and angle adjusting function, it is possible to achieve the optimum arrangement by determining the angle and position flexibly while maintaining the distance from the driver's eyes in response to the entering direction and angle of a light which prevents the driver's view, and the position of light source, etc.

[0082] In the above, one embodiment of the present invention is explained by referring the drawings, and the present invention is not limited to the embodiment, and there are other improved embodiments and modified embodiments within the scope of the concept and teaching claimed in the patent claims. Therefore, it is easy to understand for a person skilled in the art that those improved embodiments and modified embodiments are included in the scope of the present invention. For example, in the sun visor for automobile of the present invention, the hinge part and the joint can be integrated to form a single part and, in that case, the hinge part and the joint may not be moved with each other.

INDUSTRIAL APPLICABILITY

[0083] According to the sun visor for automobile of the present invention, since the sun visor that has a plurality of sliding functions and angle adjusting functions which can move and rotate a screen to shield a light flexibly, and the sun visor can be arranged in response to the position of a light source and the incident angle by adjusting freely the position and angle in the front-back direction and the position and angle in the crosswise direction.
