Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a wiper.

[0002]

[Prior art]

 When driving a car, it can be said that the driver's vision and gaze are very important in front of the windshield glass. Like the human eyes, the wiper plate is the most effective. As the wiper swings, it wipes off dust and rainwater on the windshield glass, so that a bright and clear view is always maintained.

[0003]

[Problems to be solved by the invention]

 However, conventionally, when a strong wind or a breeze blows during the operation of a car, the existing wiper causes the air flow to be directed to form an air flow. Then, a turbulence phenomenon occurs between the intersection angles of the engine cover and the window glass. When wiping dust and rainwater from the windshield glass, the windshield wiper shakes, and at the same time, slightly drifts and jumps due to wind resistance. As a result, the wiper rubber wiped flakes cannot contact and adhere to the glass surface, and the wiper wiping effect is reduced.

[0004] Other approaches are to form a wiper plate integrally formed and bent, or to employ a bent side arc plate or arc seesaw plate on one side. However, in these structures, when a strong wind or a weak wind resistance is encountered, a force is applied unevenly due to the bent side arc plate or the arc-shaped seesaw plate, and the pressure is inclined and pressed. Therefore, the rubber plate of the wiper is vertical, so it cannot be stably and durably contacted with the glass surface and cannot be stuck, causing a jumping phenomenon and not being able to wipe off dust and rainwater. The driver's line of sight is disturbed and traffic accidents are likely to occur. An object of the present invention is to provide a wiper in which a rubber plate is stably stuck to the surface of glass vertically and wipes dust and rainwater.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, a wiper according to the present invention includes a wiper plate integrally formed by press working. Then, several base pedestals and wipes are completely covered with rubber to extend the service life. When wind blows directly from the wiper plate formed by bending and forming an arc, resistance acts to disturb the air flow. The wiper plate is a vertical type that is attached to the glass surface and wipes off dust and rainwater.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, the wiper according to one embodiment of the present invention mainly includes a rubber wiping piece 40 for wiping dust and rainwater from a vehicle glass or a window. At its upper end, a bent base frame 30 for several clips is provided at an equal distance from the center. Both sides of the base frame 30 have a hook shape, and are often clipped by the concave grooves of the rubber wiping thin piece 40. A through hole is provided in a convex arc portion near the center, and a slightly larger bent support frame 20 is fitted and connected. The folded support frame 20 is made in the same manner as the folded base frame 30. That is, a through hole is similarly formed in the convex arc portion near the center. Thus, the central through-hole of the support frame 20 and the plate bent downwardly of the wiper plate are joined. Since holes were formed in the plate bent downward by press working, the plate was joined to the support frame 20 with rivets. The base frame, support frame, and wiper plate are all joined with rivets. The design features of the wiper plate are as follows.

[0007] The wiper plate is manufactured by molding a metal material with a press die or by using an injection molding die. The center of the wiper plate 10 is a flat plate. Through holes are stamped into the bent plate at appropriate locations to join the connector ends of the car wiper. The bent plate 13 is machined by pressing along the direction of the wiper plate's equiaxed axis and symmetrically through holes and downward. Downward, the bent plate 13 is rivet fastened through a through hole on the convex arc of the support frame 20 having a slightly larger bent shape. At the front end of the flat plate, a bent shape is processed by a press. When examined from the whole, the wiper plate has a curved surface that is bent downward or warped upward, like a streamline. Therefore, the rubber wiping thin piece 40 vertically attached to the glass window has a resistance to the wind blown directly from above, and has an action of disturbing the air flow. The wind flows forward along the streamlined wiper plate due to resistance. In other words, the whole wiper plate is stuck to the surface of the window glass stably and durably at a vertical angle. The rubber wiper flakes can effectively keep the driver's line of sight while driving, effectively removing dust and moisture on the surface of the glass window.

FIG. 4 shows a preferred embodiment of the wiper plate of the present invention. The upper end of the rubber wiping sheet 40 is clipped by the base frame 30, the support frame 20, and the wiper plate 10 for covering. The wiper plate has an arcuate curved surface that bends downward or curves upward, like a streamline. Therefore, the wiper plate is stuck vertically to the glass window. The design of the arc-curved wiper plate creates a wind resistance between the intersection of the engine cover and the windowpane, disrupting the airflow. The wind blows straight ahead and flows along the streamlined wiper plate in the forward direction. In other words, the wiper plate not only has the property of being pushed down, but is also stably and durably attached to the surface of the window glass, and the rubber flakes easily remove dust and moisture on the surface of the glass window.

[0009]

[Effect of the invention]

 In summary, the wiper according to one embodiment of the present invention is integrally formed by pressing. The wiper plate that is bent downward or warped upward is joined and covered from the bottom with the support frame, base frame, and rubber wipes. Thereby, an action of disturbing the air flow occurs. The wind that blows from directly flows in the forward direction. The wiper plate is then stuck vertically, stably and durably on the surface of the windowpane. If it is applied, it matches the gist of the utility model, such as inventive step and practicality. However, the above description is only for the ideal embodiment of the present invention, and does not limit the scope of the present invention. In the spirit of the invention, any similar changes or modifications are within the protection scope of the invention.
