It is a partial front view of the side visor as above. FIG. 2 is a cross-sectional view taken along the line AA in FIG. FIG. 2 is a cross-sectional view taken along the line BB in FIG. It is a partial front view of the side visor which concerns on other embodiment of this invention. It is sectional drawing of the side visor which concerns on still another Embodiment of this invention.

An embodiment of the present invention will be described with reference to FIGS. 1 to 4.

In FIG. 1, reference numeral 1 denotes a vehicle, which is provided with a vehicle body 2, and front doors 3 and rear doors 4 are provided on the left and right sides of the vehicle body 2 so as to be openable and closable (rotatable). Has been done.

The visor mounting portion 7 on the upper side of the window portion (front window portion) 6 of each of the left and right front doors 3 is a front side visor made of synthetic resin (longitudinal in the front-rear direction) along the front-rear direction of the vehicle. 1 side visor) 8 is fixedly attached.

Similarly, the visor mounting portion 10 on the upper side of the window portion (rear window portion) 9 of each of the left and right rear doors 4 is a rear side made of synthetic resin having a longitudinal shape (longitudinal direction in the front-rear direction) along the front-rear direction of the vehicle. The side visor (second side visor) 11 is fixedly attached.

Of the four side visors 8 and 11 on the front, rear, left and right, for example, two side visors (door visors for the rear door, which are side visors on the rear window) 11 on the left and right sides on the rear side improve the running stability of the automobile 1. It also has an additional function that is an aero-stabilizing fin function for the purpose. Both side visors 11 fixed to the left and right visor mounting portions 10 on the left and right side surfaces of the automobile 1 are formed in a symmetrical shape with each other.

As shown in FIGS. 2 to 4, the side visor 11 includes a visor body 13 that is longitudinally longitudinal in the front-rear direction and is fixedly attached to a visor mounting portion (for example, a part of a window frame) 10 located at the upper part of the rear door 4. A plurality, that is, for example, two that are integrally projected outward from the outer surface (outer surface) on the rear end side of the visor body 13 to generate a vortex-shaped airflow (vertical vortex) for stabilizing the running of the automobile 1. It is equipped with fins (rectifying fins) 14 for generating vortices.

It should be noted that the two parallel fins 14 that are vertically separated from each other and slightly offset from each other over a predetermined distance have similar shapes that differ only in size from each other, and in this illustrated example, they are on the lower side. The fin 14 (14a) is formed to be one size larger than the upper fin 14 (14b). For example, although not shown, on the contrary, the upper fin may be formed larger than the lower fin, the upper fin and the lower fin may be formed to have the same size, and the position in the front-rear direction may be further increased. It may be the same and may be arranged one above the other.

The visor main body 13 has a longitudinal direction in the longitudinal direction of the vehicle and is formed in a plate shape in the longitudinal direction, and has substantially the same length dimension as the longitudinal dimension of the rear door 4 (FIG. 1). reference). The visor main body 13 has a longitudinal mounting plate portion 21 in the front-rear direction that is fixedly attached to the visor mounting portion 10 using a fixing means (not shown) such as double-sided tape, and a lower end portion of the mounting plate portion 21. It has an eaves plate portion 22 that is long in the front-rear direction and is connected to the eaves plate portion 22 in the front-rear direction.

The mounting plate portion 21 is composed of only a flat flat plate portion 23 elongated in the front-rear direction (front-rear direction of the vehicle). The eaves plate portion 22 is composed of an upper curved surface-shaped curved plate portion 24 and a lower flat flat plate portion 25.

The fins 14 (14a, 14b) are laterally projecting portions (protruding portions along the front-rear direction of the vehicle) made of the same material as the visor main body 13 in the front-rear direction, and the eaves plate portion of the visor main body 13. On the outer surface on the rear end side (outer surface near the rear end) of the flat plate portion 25 of 22 is integrally projected outward in a mountain-shaped cross section and a bulge.

That is, the visor body 13 and the fins 14 are integrally molded with, for example, a light-transmitting synthetic resin (black translucent acrylic resin, etc.). More specifically, the fin 14 is manufactured at the same time as the visor main body 13 when the visor main body 13 is manufactured by injection molding using a mold having a desired shape, and the fin 14 is manufactured on both sides of the visor main body 13. It is not retrofitted with tape or adhesive. That is, the fin 14 is not configured by retrofitting a fin separate from the visor body 13. The material of the fin 14 is preferably the same resin material as that of the visor main body 13, but may be integrally formed of another material different from the material of the visor main body 13.

As shown in FIG. 2, the fins 14 are formed in a substantially elliptical shape having a long axis in the horizontal direction (front-back direction) in front view on the outer surface of the eaves plate portion 22 of the visor main body 13. On the rear end surface of the fin 14, a substantially triangular planar cut surface 27 orthogonal to the outer surface of the flat plate portion 25 having a vertical surface shape (including a substantially vertical surface shape) in the eaves plate portion 22 of the visor body 13 is formed. ing.

That is, the rear end surface of the fin 14 is composed of a cut surface 27 erected orthogonally to the outer surface of the flat plate portion 25 of the eaves plate portion 22, and therefore, immediately after the cut surface 27, the cut surface 27 is formed. There is a space 28 in which a spiral airflow is generated to stabilize the traveling of the automobile 1.

Further, as shown in FIG. 3, the fin 14 has an isosceles triangle shape having a vertical cross section (vertical cross section) having an apex at the outer end, and is an inclined upper surface that gradually descends toward the outside. It has an inclined surface 31 and an inclined lower inclined surface 32 that gradually rises toward the outside, and both of these inclined surfaces 31 and 32 are curved at the apex and smoothly connected to each other. The area of the vertical cross section of the fin 14 is maximum near the center in the front-rear direction (a position slightly before the center in the front-rear direction), and gradually decreases toward the front and the rear.

Further, as shown in FIG. 4, the fin 14 has a wing-shaped cross section (horizontal cross section), and the protrusion dimension of the fin 14 with respect to the outer surface 22a of the eaves plate portion 22 of the visor body 13 is It increases in a curved line from the front end toward the center in the front-rear direction, and decreases linearly from the center in the front-rear direction toward the rear end. That is, the fin 14 has a ridge line 38 consisting of a curved line 36 on the front side and a straight line 37 on the rear side (this FIG. 4 is a cross-sectional view of the lower fin 14a, but the upper fin 14b. The same applies to the cross section, and the upper fin 14b also has a ridge line 38 composed of a curved line 36 on the front side and a straight line 37 on the rear side).

In the example shown in FIG. 4, for example, the protruding dimension (height dimension) a of the cut surface 27 which is the rear end surface of the fin 14 is the same as the thickness dimension b of the eaves plate portion 22 of the visor main body 13 (substantially the same). Including). However, the present invention is not limited to this, and for example, the protruding dimension a may be larger than the thickness dimension b, and conversely, the protruding dimension a may be smaller than the thickness dimension b.

Next, the operation of the side visor 11 and the like will be described.

When the left and right side visors 11 are fixedly attached to the visor mounting portions 10 located at the upper parts of the left and right side surfaces of the automobile 1, the fins 14 (14a, 14b) of the left and right side visors 11 are attached to the left and right sides of the automobile 1. It is positioned and fixed at a predetermined position on the upper part of the side surface.

Therefore, the fins 14 forming a left-right pair (for example, a plurality of pairs) are fixedly arranged at positions symmetrical with respect to the width center line along the front-rear direction of the vehicle body 2 of the automobile 1.

Therefore, when the automobile 1 is traveling, a vortex-shaped airflow, that is, a regular vertical vortex is generated behind both the left and right fins 14, and the generated vertical vortex presses the vehicle body 2 of the automobile 1 from the left and right. As a result, the traveling of the automobile 1 is stable, and excellent steering stability can be obtained.

As described above, according to the side visor 11, in order to provide the visor main body 13 and the fins 14 for generating vortices integrally projected outward from the visor main body 13, the side visor 11 is attached to the left and right visors. By simply attaching to each of the portions 10, not only the design is improved, but also the running stability of the automobile 1 is improved, and excellent steering stability can be obtained.

Further, the rear end side of the side visor 11 becomes thicker by the amount of the plurality of laterally protruding fins 14, and the strength is improved. Therefore, for example, when the rear door 4 is opened, the rear end side of the eaves plate portion 22 of the side visor 11 is opened. Even if the side interferes with other objects, there is less problem of damage and durability can be improved.

Further, since the visor body 13 and the fins 14 are integrally molded by a synthetic resin having light transmission, the number of parts can be reduced as compared with the case where the visor body and the fins are separate bodies, and the desired shape can be obtained. By injection molding using the mold of No. 1, the side visor 11 having an additional function can be easily mass-produced.

In the above embodiment, the configuration in which the two fins 14 (14a, 14b) are integrally projected on the outer surface of the rear end side of the visor main body 13 has been described, but the configuration is not limited to the two, for example. Three or more may be used, or one fin 14 may be integrally projected from the visor body 13 as shown in FIG. 5, that is, the number of fins is arbitrary, and the position of the fins is also arbitrary.

Further, the shape of the fin 14 is not limited to the illustrated example, and may be any shape as long as it can exert a function of generating a spiral air flow for stabilizing the running of the vehicle, for example, the shape of the visor body or the shape of the vehicle. Etc., it may be changed to another shape as appropriate.

Further, for example, the fins may be integrally projected on the visor bodies of the two front side visors, or the fins may be integrally projected on the visor bodies of the four front, rear, left and right side visors.

Further, for example, in a side visor with a molding, fins may be integrally projected from the molding portion of the visor body.

Further, for example, a light source that shines in conjunction with the direction indicator of the automobile may be provided in the fin, or a character or the like indicating the vehicle type of the automobile may be displayed on the fin.

Further, for example, as shown in FIG. 6, the side protruding fins of the inner surface 22b of the eaves plate portion 22 of the visor main body 13 so that the thickness of the plate-shaped side visor 11 becomes constant (including substantially constant) throughout. A recess 41 may be formed in a portion corresponding to 14.
