Description

[Detailed Description of the Invention] This invention relates to a lifting prevention device that prevents the wiper blade from lifting up when wiping a glass surface with the wiper blade.

Wipers, which are generally installed on vehicles, automatically wipe away rainwater, snow, mud, dust, and other impurities that adhere to the windshield and rear glass surfaces of the car, ensuring the driver's forward and rearward visibility. This is an important role to play.

By the way, there are two types of wipers conventionally used in vehicles: two-piece wipers and one-piece wipers. As the surface area of the glass to be wiped becomes larger, the amount of water to be wiped increases as well.
The wiping speed must also be fast. For this reason, when driving in rainy weather, there is a problem in that rainwater wiped off by the wiper blades scatters in the left and right directions of the vehicle, splashing onto pedestrians and vehicles traveling adjacent to the vehicle, causing an unpleasant feeling.

On the other hand, since the wiper blade receives wind pressure from the front when the vehicle is running, the wiper blade often lifts off the glass surface and cannot perform an accurate wiping operation.

For this reason, in the past, measures to prevent the wiper blade from lifting up have been taken by increasing the pressure on the wiper arm or changing the shape of the wiper blade lever, but the structure is complicated. There was a problem in that the manufacturing time increased and the cost increased.

This invention was devised by focusing on such conventional problems, and its purpose is to effectively prevent water droplets from scattering when wiping away rainwater, etc., and to prevent wiper blades from flying. To provide a wiper blade lifting prevention device which prevents lifting and enables efficient wiping operation.

In order to achieve the above object, this invention provides a wiper blade that wipes away rainwater adhering to the glass surface of a vehicle along the shape of the glass surface.
The wiper blade is integrally formed with a blade rubber body that slides on the glass surface, and fins for preventing water droplet scattering formed along the longitudinal side edges of the blade rubber body, and these fins are connected to the wiper blade. The gist is that the wiper blade is formed at an angle that presses the wiper blade toward the glass surface with respect to the airflow on the glass surface when the blade wipes the glass surface.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a wiper blade 3 attached to a windshield 2 of a vehicle 1, and this wiper blade 3 operates to wipe in a substantially fan-like manner while slidingly contacting a glass surface P of a vehicle body 4 via a wiper pivot 5 and a wiper arm 6. is configured to do so.

The wiper blade 3 is attached to the lever 7 via a packing 8, as shown in FIG. The wiper blade 3 itself is composed of an inverted triangular blade rubber body 9 at the center and gate-shaped fins 10a and 10b integrally formed along both sides of the blade rubber body 9 in the longitudinal direction.

When the wiper blade 3 wipes in the left and right direction along the glass surface P, the neck portion 1
The blade rubber body 9 swings in the left-right direction centering on the edge portion 1 at the tip of the blade rubber body 9.
2 and the lip portion 13 to wipe away rainwater and the like.

As shown in FIG. 3, the fins 10a and 10b integrally formed with the blade rubber body 9 move the wiper blade 3 toward the windshield in response to the wind flow _F1 hitting the windshield 2 of the vehicle 1 while the vehicle is running. It is formed so as to be inclined toward the direction _F2 in which it is pressed against the second side.

Therefore, the wind flow F ₁ (wind force) that hits the windshield 2 while driving flows toward the windshield 2 along the fins 10a, 10b, and a force is generated in the direction of pressing the wiper blade 3 against the windshield 2.
This is converted into _F2 and prevents the wiper blade 3 from lifting up.

In addition, in the above embodiment, the blade rubber body 9
Although the fins 10a and 10b are integrally formed, a packing-integrated type or a separate attachment type can also be used.

This idea uses the fins formed along the longitudinal side edges of the blade rubber body as described above to move the wiper blade toward the glass surface side against the airflow on the glass surface when the wiper blade wipes the glass surface. Because it is formed at an angle that allows it to be pressed,
At the same time, it prevents water droplets such as rainwater from scattering, and at the same time prevents the wiper blade from lifting up, allowing for efficient wiping work.Furthermore, it secures the driver's visibility while the wiper blade is operating, increasing safety. It has the effect of improving

Furthermore, since the structure is simple, it can be manufactured at low cost.
