来のワイパーをなくし、運転視界を良好に、且つ
広くすることができる。DETAILED DESCRIPTION OF THE INVENTION The present invention is a device in which a rain shield plate is attached to the front upper part of the windshield of an automobile, etc., and a mirror is provided on this plate so that the driver can see the front and rear of the vehicle. This makes it possible to improve and widen the driving field of view.

者の視野を妨げ、交通事故発生につながるもので
あつた。 FIG. 1 shows a conventional running car. Airflow 3 that hits the windshield 2 from the front of the car 1 and rises does not flow along the surface of the roof 4, but creates a vortex 5, which increases the air resistance of the car body. Fuel consumption increases, and since rain 6 falls on the surface of the windshield 2, which is tilted upward, not only when the vehicle is running but also when the vehicle is stopped, the rainwater on the windshield surface must be removed by moving the wiper 7 from side to side. This obstructs the driver's field of vision, leading to traffic accidents.

得られない。 In order to eliminate this wiper, attempts have been made to treat the windshield surface with water repellent or hydrophilic treatment, but the vehicle speed is not sufficient to blow off the water film, and the raindrops and water film on the windshield surface are not strong enough. The uniform flow disrupts the perspective, making it impractical. Furthermore, the rearview mirrors 1' provided on both sides of the vehicle do not provide sufficient rearward visibility.
本発明は前記のごとき従来の問題をすべて解決
するものである。 The present invention solves all of the conventional problems as described above.

を低減させることができる。 FIGS. 2 to 9 illustrate the wing-shaped plate used in the present invention, which is designed to prevent rain 6 from directly hitting the windshield 2 of the automobile 1 and to maintain driving visibility through the windshield. A wing-shaped plate 8 is provided above, spaced apart from the windshield, substantially horizontally, downwardly curved, or in the form of a flat plate. As a result, airflow 3 from the front of the car 1
is the airflow 9 between the windshield 2 and the wing plate 8
The airflow 10 is divided into the airflow 10 outside the wing-shaped plate 8.
The flow velocity V1 of the airflow 9 becomes faster than the flow velocity V2 of the airflow 9,
Since the swirl that is about to occur on the roof 4 is struck by the airflow 10 and its occurrence is suppressed, fuel consumption can be reduced.
また、自動車が比較的低速走行のとき、図示の

したとき、雨は速度Ｖ５でフロントガラス２に当
たろうとするが翼状板８により遮断されてフロン
トガラス２に当らず、従つてワイパーが不要とな
る。 Further, when the car is running at a relatively low speed, and the falling speed of the rain is V3 and the speed of the car is V4 in the vector diagram shown, the rain tries to hit the windshield 2 at a speed of V5, but is blocked by the wing plate 8. The wiper does not hit the windshield 2, so a wiper is not needed.
勿論補助的にワイパーを設けてもよいがこの場
合、翼状板８とフロントガラス２の間に間隙１１
があるためこれにワイパーを自由に作動するよう
に設けることができ、また、フロントガラスを拭
く場合でもこの間隙１１に手を入れて拭くことが
できる利点がある。 Of course, an auxiliary wiper may be provided, but in this case, the gap 11 between the wing plate 8 and the windshield 2
Because of this, a wiper can be installed in this space so that it can be operated freely, and there is also an advantage that when wiping the windshield, you can insert your hand into this gap 11 and wipe it.
さらに自動車が高速走行のときには翼状板８と
フロントガラス２による気流９，１０に雨６が乗
つて後方に吹き飛ばされ、フロントガラスには雨
が当らない。 Further, when the automobile is running at high speed, the rain 6 is carried by the air currents 9 and 10 generated by the wing plate 8 and the windshield 2 and blown backward, so that the rain does not hit the windshield.
翼状板８は、透明又は不透明あるいはスモーク
又は着色したプラスチツク板から成り、第３図の
ごとく断面形状は平板１２、下向き湾曲板１３、
クラークＹ型断面１４、上向き湾曲板１５、逆ク
ラークＹ型断面１６などがある。 The wing-like plate 8 is made of a transparent, opaque, smoked or colored plastic plate, and as shown in FIG. 3, the cross-sectional shape is a flat plate 12, a downwardly curved plate 13,
These include a Clark Y-shaped cross section 14, an upwardly curved plate 15, and a reverse Clark Y-shaped cross section 16.
第４図は翼状板として逆クラークＹ型断面板１
６をフロントガラス２の前上方に設けた実施例で

面の流速Ｖ２よりも大きくなるので雨６は前方か

方に吹飛ばされるのでフロントガラスに雨がかか
らずワイパー不用となる。 Figure 4 shows an inverted Clark Y-shaped cross section plate 1 as a wing plate.
6 is provided above the front of the windshield 2, and since the flow velocity V1 on the Clark Y curved surface is greater than the flow velocity V2 on the Clark Y plane, the rain 6 is guided from the front to the rear, becomes almost horizontal, and flows backward from the gap 11. Since the rain is blown away by the windshield, there is no need for windshield wipers.
又Ｖ１＞Ｖ２により湾曲板１６は下方即ち車体
側に押さえられて安定して車体に支持でき、且つ
車体をおさえて前輪を地面に押しつけるので車を
安定して走行させることができる。 Further, since V1>V2, the curved plate 16 is pressed downward, that is, toward the vehicle body, and can be stably supported by the vehicle body. Furthermore, since the vehicle body is held down and the front wheels are pressed against the ground, the vehicle can be driven stably.

Reference numeral 5 denotes an embodiment of the present invention in which the front of the vehicle can be viewed with a line of sight 29 reflected by mirrors 26 and 28, or the rear of the car can be viewed with a line of sight 30 reflected by mirrors 27 and 28, that is, the lane direction can be seen. ,2
7 is in a high position, so the field of view is wide and you can see it like a telescope.
本発明は前記の構成から次のごとき多くの著効
をあわせ有するものである。 The present invention has the following many advantages due to the above-mentioned configuration.
(1) 走行車体を包む気流の渦巻等の乱れによる抵
抗係数CDを小さくして燃費を節減することが
できる。(1) It is possible to reduce fuel consumption by reducing the drag coefficient C D caused by turbulence such as swirls in the airflow surrounding the running vehicle.
(2) 高速走行時に雨が振つてもフロントガラスへ
の雨を翼状板で生じる気流で後に吹飛ばしフロ
ントガラスに雨が付着しないようにするととも
に、低速走行ときにはフロントガラスへの雨を
翼状板で直接遮断するので、従来専ら使用され
ていたワイパーが全く不要となるので視野をさ
えぎるものがなくなり視界を完全に確保でき、
また、ワイパーのごとき作動機能部分がないの
で故障がなくなる。(2) Even if rain falls on the windshield when driving at high speeds, the airflow generated by the wing-like plates blows the rain away from the windshield and prevents it from adhering to the windshield, and when driving at low speeds, the wing-like plates blow away the rain onto the windshield. Since it is directly blocked, there is no need for the wiper that was used exclusively in the past, so there is nothing to obstruct the field of view, and the field of view can be completely secured.
Also, since there are no operating parts such as wipers, there will be no malfunctions.
(3) 翼状板にミラーを取付けると、従来のバツク
ミラーよりも高い位置で、且つ大きいミラーと
することができるので、きわめて広く見易いバ
ツクミラーとなる。さらにテレスコープ機能を
得ることができる。(3) By attaching the mirror to the wing plate, the mirror can be placed higher and larger than conventional back mirrors, resulting in an extremely wide and easy-to-see back mirror. Additionally, you can get a telescope function.
(4) 車走行時の気流により翼状板を下方におさえ
つける力が働く用にすることかできるので翼状
板を車体に安定して固定できる。(4) The wing-shaped plate can be stably fixed to the vehicle body because the airflow when the car is running can exert a force to hold the wing-shaped plate downward.
(5) 前項の場合、車速度が上昇するに従い車体に
取付けた翼状板を押下力が強くなるために自動
車の前輪を地面におしつけスリツプが防止され
るので、高速走行性が自動的に向上する。(5) In the case of the previous item, as the vehicle speed increases, the force pressing down on the wing plate attached to the vehicle body becomes stronger, which forces the front wheels of the vehicle onto the ground and prevents slipping, automatically improving high-speed running performance. .
以上のごとく本発明は自動車等のワイパーが不
要となり、構造簡易化、運転の安全性、車体周囲
の渦流防止による燃費低下およびバツクミラー、
テレスコープ機能、高速走行安全性などきわめて
多大の効果をもたらす画期的な発明である。 As described above, the present invention eliminates the need for wipers for automobiles, etc., simplifies the structure, improves driving safety, reduces fuel consumption by preventing swirling around the vehicle body, and improves rear view mirrors.
This is an epoch-making invention that brings tremendous benefits such as telescope function and high-speed driving safety.
