種の浮き上逆防止装置が案出されている。BACKGROUND OF THE INVENTION In the case of wipers for automobiles, various lifting prevention devices have been devised to prevent wiper blades from lifting when driving at high speeds in the rain and causing noises caused by poor wiping.

設されている。To explain this example with reference to FIG. 7, the central part of the primary lever 2 is pivotally supported at the tip of the wiper arm 1,
A secondary lever 4 having a yoke 6 pivoted on the -0'Mt side is pivoted at the center of the primary lever 2, and the primary lever 1. Secondary lever 4I yoke 6
A blade rubber 6 is attached to each end of the blade via a backing 5.

は特開昭５７−９２８号に示されている）。Here, as shown in FIG. 8, the primary lever 2 has linear reinforcing members 8 and 9 fixed to the upper surface on the downstream side and the lower surface on the upstream side of the flat plate 7, respectively. 9
Negative pressure area Xvil- is generated on the lower surface of the rainbow flat plate 7 due to separation of the airflow A passing through the lower side, while stagnation of the airflow B flowing over the upper side of the linear reinforcing member 8 on the downstream side is caused. A positive pressure area Y is created on the upper surface of the flat plate 7, and the entire blade rubber 6 is pressed against the window glass W surface by the pressure difference between the upper and lower surfaces of the flat plate 7, thereby preventing the lifting from reverse. (shown in 1983-928).

ドラバー６が浮き上がる方向に力？受けてし筐う。Problems to be Solved by the Invention In the floating prevention device as described above, the air flow A is between the flat plate 7 and the secondary lever 4, and the air flow C is between the secondary lever 4 and Since the flow is contracted between the backing 5 on the upper part of the blade rubber 6, there is no strong negative pressure between the backing 5 and the upper surface of the secondary lever 4, and the window glass W surface and the tip of the blade rubber 6 are closed. Since the corner part of the blade is under positive pressure due to the stagnation, there is a force in the direction that the blade rubber 6 is lifted up. I'll accept it.

う問題点がめる。Although a negative pressure region X is generated on the back surface of the linear reinforcing member 9 on the upstream side, the flow velocity at the lower part 2 of the linear reinforcing member 8 on the downstream side of the air flower is not so high and the negative pressure region X
In this case, a large pressure reduction effect cannot be expected at all, and as a result, the blade rubber 6 is raised at D', which is a problem.

壁２ｂ、４ｂ。The outer portions of the brimary lever 2 and the secondary lever 4 and the outer portion of the yoke 6 constituting the upper edge of the wiper blade B have wall portions 2a and 4a on the leeward side, respectively.
3a is extended to the part where the upper edge of the blade rubber 6 is loosened, and the bridging lever (-2, secondary lever 4) is connected to each wall portion 2a+4a, 3a, and each upper wall 2b, 4b of the yoke 6 .

追従できるようになっている。In addition, the above-mentioned primary lever 2, secondary lever 4. The yoke 6 is supported by a binding joint P, and the wall portions 2a, 4a, and 3a are arranged so that their side edges overlap each other, so that the blade rubber 6 curves along the surface of the window glass W. against the primary lever 2. Secondary lever 4. Yoke 3 is designed to be able to follow freely.

域Ｙが形成される。According to the structure of the above embodiment, when a car runs at high speed in rainy weather with the wipers being driven, wind blows from the left side of the figure toward the wall 2a, as shown in FIG.
This causes stagnation between the upper wall 2b and the upper surface 6a of the blade rubber 6. On the other hand, since the air current constantly flows around the wiper blade, a relatively positive pressure region Y is formed in this area.

れる。This positive pressure area YK presses the upper surface 6a of the blade rubber 6 and air vent hole 2C formed in the upper wall 2a.
A downward force acts on the outer side of the secondary lever 4 and the yoke 6 due to the reaction of the change in momentum of the air flow blown upward from the yoke. It will be done.

生ずることにない。Therefore, the pressure around the secondary lever 4 or the box 230 located within the area surrounded by the wall portion 2a is approximately uniform, so that the secondary lever 4. Unlike when air flows between the yokes 6, no unnecessary lifting force is generated.

少ない揚力３０．９という結果を得ている。Specifically, as shown in Figure 3, according to a comparative wind tunnel experiment with the current product without walls, the wind speed was 120km/h.
At h, the lift force of the current product is about 120S, while the result is a lift force of 30.9, which is 75% less.

約３０ｋｍ／ｈも上回る良好な結果が得られた。As shown in Figure 4, we conducted a wiping performance test while spraying water in a wind tunnel for actual vehicles. As shown in Figure 4, the current product's limit vehicle speed (vehicle speed when driving is difficult and the rating is 2.5) was approximately Good results were obtained, exceeding 30 km/h.

作用させて揚力を減少させるようにしたものである。In the embodiment shown in FIG. 5, an overhanging part 20b is formed at the lower end of the wall part 2a toward the leeward side and extends in the horizontal direction 20a, and a pressing force is applied further downward by the area of the horizontal direction 20a. It is designed to reduce the lift force.

ことも出来る。Furthermore, even if the wall portion 2a is provided only on the primary lever 2 that can secure a relatively large area as in the embodiment shown in FIG. A favorable result was obtained. In the above-described embodiment, the wall portion was provided separately from the main lever or the sub lever (-), but the lever is not limited to this, and it is also possible to form the lever from synthetic resin and provide the wall portion integrally therewith.

いう実用上多大な効果を有する。As described in detail, according to the present invention, the airflow hitting the walls of the main lever and the sub-lever causes stagnation, and the resulting pressure is used to control the motion of the airflow blown out from the air vent hole. Because it uses the reaction of change, compared to a structure in which air flows between the sub-levers, it minimizes the influence of the air flow on the sub-levers and effectively prevents them from floating, which is a great practical advantage. It has a great effect.
