Therefore, the vehicular visor device can suppress sunlight from hindering vision of an occupant P more than before, when the transparent panel 20 is postured so that the lower end face 21 is horizontal, and the sunlight is introduced from above in a vertical direction to the transparent panel 20 and thereby the lower end face 21 shines.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a visor (sun visor) device for a vehicle.

  Registered Utility Model No. 3007189 discloses a vehicle visor device having a translucent transmissive panel made of a single rectangular plate and a support portion for mounting and supporting the transmissive panel on the ceiling of the passenger compartment. doing.

  By the way, sunlight introduced into the transmissive panel may be diffusely reflected and shine on the lower end surface (the upper surface) of the transmissive panel, thereby obstructing the field of view of the vehicle occupant. In particular, when the lower end surface is horizontal and sunlight is introduced into the transmissive panel from vertically above (including substantially vertically above), that is, the incident angle of sunlight to the lower surface (upper surface) of the transmissive panel is When the angle is close to 90 degrees (when the incident angle is close to 0 degrees, when the incident angle is close to the direction perpendicular to the lower end face of the transmissive panel), the lower end face is more brilliant because the energy of light becomes stronger. As seen from the occupant, the larger the area that the lower end surface can be seen, the larger the area that appears to shine.

Here, in the apparatus disclosed in the above publication, the lower end surface of the transmission panel in a posture extending in the vertical direction is a horizontal plane. For this reason, when the transmissive panel is in a posture in which the lower end surface is horizontal and sunlight is introduced into the transmissive panel from vertically above (including substantially vertically above) and the lower surface (upper surface) shines, There is room for improvement in terms of suppressing obstruction.

Registered Utility Model No. 3007189

  The object of the present invention is to suppress the obstruction of the occupant's field of view when there is a transmission panel in a posture where the lower end surface is horizontal and sunlight is introduced into the transmission panel from vertically above and the lower end surface shines compared to the conventional case. An object of the present invention is to provide a vehicle visor device.

The present invention for achieving the above object is as follows.
(1) A vehicle visor device having a translucent transmissive panel made of a single rectangular plate and a support portion that supports the transmissive panel so as to be rotatable in the vertical direction.
A visor device for a vehicle, wherein a lower end surface of the transmission panel in a posture extending in a vertical direction is an inclined surface that is inclined rearward and upward.
(2) The inclination angle of the inclined surface is an angle that coincides with the tangent line on the upper side of the icon that passes through the inclined surface when viewed from the vehicle left-right direction when the transmission panel is in a posture extending in the vertical direction. The vehicle visor device according to (1).
(3) The left and right side surfaces when the transmission panel is in a posture extending in the vertical direction are side inclined surfaces that are inclined rearward of the vehicle and toward the left and right center of the transmission panel, (1) or (2 The vehicle visor device described in the above.

According to the vehicle visor device of (1) above, the lower end surface of the transmission panel is an inclined surface that is inclined rearward and upward of the vehicle. For this reason, compared with the case where the lower end surface of the transmissive panel is a horizontal surface (conventional), the lower end surface (upper surface) can be seen from the occupant when the transmissive panel is in a posture where the lower end surface is horizontal (area). Can be reduced. Therefore, when the transmission panel is in a posture in which the lower end surface is horizontal and sunlight is introduced into the transmission panel from vertically above (including substantially vertically above) and the lower end surface (the upper surface thereof) shines, the occupant's view is obstructed. This can be suppressed compared to the conventional case.

  According to the vehicle visor device of the above (2), the effect obtained by the above (1) can be obtained regardless of the occupant's physique.

According to the vehicle visor device of (3) above, the left and right side surfaces of the transmissive panel are laterally inclined surfaces that are inclined rearward of the vehicle and toward the left and right center side of the transmissive panel. Compared with the case where the plane is orthogonal to the left-right direction, the range (area) in which the left and right sides can be seen from the occupant can be reduced. Therefore, it can suppress that the both right and left side surfaces of a transmissive panel obstruct | occlude a passenger | crew's visual field.

It is a schematic sectional drawing of the visor apparatus for vehicles of this invention Example, and its vicinity. In FIG. 1, the cross-sectional display is omitted for clarity of the drawing. It is an expanded sectional view of a lower end surface and its vicinity when a transmissive panel exists in each position of (a), (b), (c) of FIG. It is a schematic cross section when the transmission panel of the visor device for a vehicle according to the embodiment of the present invention is cut in a direction orthogonal to FIG. It is a partial expanded sectional view which shows the modification of the visor apparatus for vehicles of this invention Example.

  Hereinafter, a vehicle visor device according to an embodiment of the present invention (hereinafter also simply referred to as a visor device) will be described with reference to the drawings. In the figure, FR indicates the front of the vehicle and UP indicates the upper side.

As shown in FIG. 1, a vehicle visor device 10 according to an embodiment of the present invention is provided in front of a vehicle in a driver's seat and / or a passenger's seat at or near a vehicle front end portion of a passenger compartment ceiling 1. The visor device 10 is provided mainly for light shielding of the occupant P seated in the front seat (driver's seat, front passenger seat) of the vehicle. The visor device 10 includes a transmissive panel 20 and a support unit 30.

The transmission panel 20 is made of a single rectangular plate. The transmissive panel 20 is made of a translucent resin having a light transmittance of 1% or more and 99% or less. The transmissive panel 20 is made of, for example, acrylic resin or polycarbonate resin. The transmissive panel 20 is supported at the upper end by the support 30 so as to be rotatable in the vertical direction using a torque hinge (not shown). The transmissive panel 20 is directly supported by the support portion 30, and the lower end surface 21 and the left and right side surfaces 22 of the transmissive panel 20 are directly visible from the occupant P throughout. The transmission panel 20 is supported by the support portion 30 so as to be pivotable in the vertical direction around an axis A extending in the vehicle left-right direction. The transmission panel 20 can be held at an arbitrary vertical angle with respect to the support portion 30 by a torque hinge. When a force larger than the holding force by the torque hinge is applied, the transmission panel 20 moves up and down with respect to the support portion 30. Rotate in the direction.

The support part 30 may be fixed to the vehicle or may be supported movably. The support part 30 is arrange | positioned in the storage space S between the roof panel 2 and the roof headlining 3, for example. In addition, the code | symbol 4 in FIG. 1 is a windshield. An opening 3 a through which the transmission panel 20 is inserted is formed at the front end portion of the roof head lining 3. The support unit 30 rotates the transmissive panel 20 at least in the vertical position 20a (FIG. 1A) in which the transmissive panel 20 extends in the vertical direction, and forward and upward from the vertical position 20a to the front glass. 4 is supported so as to be rotatable at an upper position 20c ((c) in FIG. 1).

  The lower end surface 21 of the transmission panel 20 at the vertical position 20a is an inclined surface 21a that is inclined rearward and upward as shown in FIG. 2A. The inclined surface 21a is formed over the entire lower end surface 21 (including substantially the entire surface). However, as shown in FIG. 4, at least one of the end portions of the lower end surface 21 in the vehicle front-rear direction and the left and right end portions (each end portion in the width direction of the transmission panel 20 and each end portion in the vehicle left-right direction). For example, when the chamfering process of the C surface or the R surface is performed, the entire lower end surface 21 excluding the portion subjected to the process is an inclined surface 21a. It is desirable that the inclined surface 21a is a flat surface for processing.

  The inclination angle θ of the inclined surface 21a is set so that the inclined surface 21a is close to the sight line direction of the occupant P. Specifically, as shown in FIG. 1, when the transmission panel 20 is at the vertical position 20a, the inclination angle θ of the inclined surface 21a is the upper side of the icon I passing through the inclined surface 21a when viewed from the vehicle left-right direction. The angle θ1 coincides with the tangent line (upper tangent line) L. “Iconata” refers to variations in the physique of passenger P (AF05 (fifth from the small one when 100 American Females are lined up) to AM95 (from the small one when 100 American Males are lined up) This is the range where the eye position (eye point) is present in consideration of the 95th)).

The reason why the inclination angle θ of the inclined surface 21a is the angle θ1 that coincides with the tangent line L is that (i) when θ> θ1, the range of the lower end surface 21 that can be seen from the back (below) is θ = θ1. The lower end surface 21 itself becomes larger than that of the occupant P, and (ii) when θ <θ1, the effect obtained by forming the inclined surface 21a is smaller than when θ = θ1. Because.

As shown in FIG. 3, the left and right side surfaces (both side surfaces in the vehicle left-right direction) 22 of the transmissive panel 20 at the vertical position 20 a are inclined to the rear side of the vehicle and the left and right center side (width direction center side) of the transmissive panel 20. It is set as the side inclined surface 22a to do. The side inclined surface 22a is formed over the entire left and right side surfaces 22 (including substantially the entire surface). However, if at least one of the end portions in the vehicle front-rear direction and the end portions in the vertical direction of the left and right side surfaces 22 is subjected to chamfering processing on the C surface or the R surface, the processing is performed. The left and right side surfaces 22 as a whole, excluding the portions that are formed, are side inclined surfaces 22a. The side inclined surface 22a is preferably a flat surface for processing.

  Next, the operation and effect of the embodiment of the present invention will be described.

(A) Regarding the lower end surface 21 (A1) When sunlight is introduced into the transmission panel 20 from vertically above (including substantially vertically above), as indicated by the arrow S1 in FIG. 1 (i) The transmission panel 20 Is in the vertical position 20a (see FIG. 1 (a) position, FIG. 2 (a)).
The lower end surface 21 of the transmissive panel 20 shines relatively strongly because the approach angle of sunlight to the lower end surface 21 is close to 90 degrees and the energy of light is relatively strong. However, the lower end surface 21 is an inclined surface 21a. For this reason, compared with the case where the lower end surface 21 is a horizontal surface (conventional), the range (area) where the lower end surface 21 (the upper surface thereof) can be seen from the occupant P becomes smaller. Therefore, the hindrance to visibility is small.

(Ii) When the transmissive panel 20 is rotated forward and upward from the vertical position 20a and the lower end surface 21 is at a position 20b (hereinafter referred to as a horizontal position) 20b (the position (b) in FIG. 1, FIG. 2). (Refer to (b))
The lower end surface 21 of the transmissive panel 20 shines the strongest because the approach angle of sunlight to the lower end surface 21 is 90 degrees and the light energy is the strongest. However, the lower end surface 21 is an inclined surface 21a, and the vertical position of the lower end surface 21 is higher than that of the prior art by the amount rotated upward from the vertical position 20a to the horizontal position 20b. Therefore, the range (area) where the occupant P can see the lower end surface 21 (the upper surface thereof) is smaller than the conventional one. Therefore, the hindrance to visibility is small.

(Iii) When the transmissive panel 20 is in the upper position 20c (see the position (c) in FIG. 1, see FIG. 2 (c)).
The lower end surface 21 of the transmissive panel 20 shines relatively weakly because the approach angle of sunlight to the lower end surface 21 is close to 0 degrees and the light energy is relatively weak. Therefore, although the area where the lower end surface 21 (the upper surface thereof) can be seen increases as compared with when the transmissive panel 20 is at the vertical position 20a or the horizontal position 20b, the influence on the field of view is relatively small.

(A2) When sunlight is introduced into the transmissive panel 20 from the front of the vehicle and in the horizontal direction (including the substantially horizontal direction) as indicated by the arrow S2 in FIG. 1 (i) The transmissive panel 20 is in the vertical position 20a. (See position (a) in FIG. 1, see FIG. 2 (a))
The lower end surface 21 of the transmissive panel 20 shines relatively weakly because the approach angle of sunlight to the lower end surface 21 is close to 0 degrees and the light energy is relatively weak. Furthermore, since the lower end surface 21 is an inclined surface 21a, the range (area) where the lower end surface 21 (the upper surface) can be seen from the passenger P is smaller than when the lower end surface 21 is a horizontal surface (conventional). . Therefore, the visibility is small.

(Ii) When the transmission panel 20 is rotated forward and upward from the vertical position 20a to the horizontal position 20b (see (b) position in FIG. 1, see FIG. 2 (b)).
The lower end surface 21 of the transmissive panel 20 shines the weakest because the light incident angle to the lower end surface 21 is 0 degree and the light energy is the weakest (the light does not shine or is negligible). Further, the lower end surface 21 is an inclined surface 21a, and the vertical position of the lower end surface 21 is higher than that of the prior art by the amount rotated upward from the vertical position 20a to the horizontal position 20b. Therefore, the range (area) where the occupant P can see the lower end surface 21 (the upper surface thereof) is smaller than the conventional one. Therefore, the hindrance to visibility is small.

(Iii) When the transmissive panel 20 is in the upper position 20c (see the position (c) in FIG. 1, see FIG. 2 (c)).
Sunlight is reflected at the lower end surface 21 (the lower surface and the back surface thereof) of the transmissive panel 20, and the glare of the lower end surface 21 (the upper surface thereof) is relatively small. Therefore, although the area where the lower end surface 21 (the upper surface thereof) can be seen increases as compared with when the transmissive panel 20 is at the vertical position 20a or the horizontal position 20b, the influence on the field of view is relatively small.

(B) As shown in FIG. 3, the left and right side surfaces 22 are side inclined surfaces 22a as shown in FIG. 3, and therefore the left and right side surfaces 22 are planes orthogonal to the vehicle left and right direction (conventional). ), The range (area) where the left and right side surfaces 22 can be seen from the occupant P is small regardless of whether the transmissive panel 20 is in the vertical position 20a, the horizontal position 20, or the upper position 20c. Therefore, the visibility is small.

In the embodiment of the present invention, the lower end surface 21 of the transmissive panel 20 is an inclined surface 21a that is inclined rearward and upward of the vehicle. For this reason, compared with the case where the lower end surface 21 of the transmissive panel 20 is a horizontal surface (conventional), when the transmissive panel 20 is in a posture in which the lower end surface 21 is horizontal, the lower end surface 21 (the upper surface thereof) from the passenger P Can be reduced. Therefore, when the transmissive panel 20 is in a posture in which the lower end surface 21 is horizontal and sunlight is introduced into the transmissive panel 20 from vertically above and the lower end surface 21 shines, the view of the occupant P is obstructed compared to the conventional case. Can be suppressed.

  When the transmission panel 20 is at the vertical position 20a, the inclination angle θ of the inclined surface 21a is an angle θ1 that coincides with the tangent line (upper tangent) L on the upper side of the icon I passing through the inclined surface 21a when viewed from the left-right direction of the vehicle. Therefore, regardless of the physique of the occupant P, it is possible to effectively prevent the occupant P from being obstructed from view.

Since the left and right side surfaces 22 of the transmissive panel 20 are side inclined surfaces 22a that are inclined rearward of the vehicle and toward the left and right central sides of the transmissive panel, the left and right side surfaces 22 of the transmissive panel 20 are planes orthogonal to the vehicle left-right direction. Compared to the case (conventional), the range (area) where the left and right side surfaces 22 can be seen from the occupant P can be reduced. Therefore, it is possible to suppress the left and right side surfaces 22 from obstructing the field of view of the occupant P as compared with the conventional case.

Since the left and right side surfaces 22 of the transmissive panel 20 are side inclined surfaces 22a that are inclined rearward of the vehicle and toward the left and right central sides of the transmissive panel, the left and right side surfaces 22 of the transmissive panel 20 are planes orthogonal to the vehicle left-right direction. Compared with the case (conventional), when the transmission panel 20 is viewed from the lateral rear side (diagonal rear side), the left and right side surfaces 22 of the panel 20 appear thicker. Specifically, as shown in FIG. 3, the transmissive panel 20 is placed sideways compared to the thickness dimension D <b> 1 in the case where the left and right side surfaces 22 of the transmissive panel 20 are planes orthogonal to the vehicle left-right direction (conventional). The thickness dimension D2 when viewed from the rear is increased. Therefore, a profound feeling can be produced and product power can be improved.
