[Prior art]

 Conventionally, among rainwater that has fallen on the roof portion of an automobile, water that flows toward the front of the automobile has been guided downward along a window frame member that supports the windshield. However, when a running car was suddenly stopped by braking, rainwater on the roof part could overrun the window frame member due to inertial force and flow into the windshield surface, which could not be effectively prevented. , The flow of rainwater into the windshield was usually ignored because it was not a problem.

[0003]

[Problems to be solved by the device]

 However, immediately after applying the wax to the roof part of the car, if rainwater hits the roof part, the wax is easily dissolved in the rainwater and flows out easily. Rainwater containing the water flows into the windshield and forms a wax film on the windshield surface. In addition, such a wax coating may cause more complex reflection and scattering of light emitted from various external lighting devices, particularly when driving at night, and may impede the driver's perception of normal vision. there were. The present invention is intended to solve the above problems, and an object of the present invention is to provide a windshield fouling prevention member that prevents rainwater from flowing from the roof portion to the windshield surface with a simple structure.

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view schematically showing an automobile 10 to which a windshield stain prevention member 20 according to the first embodiment is applied. The windshield 11 of the automobile 10 is stably attached to the vehicle body by a window frame rubber member 13 attached to a window frame portion 12 provided on the front surface. A windshield stain prevention member 20, which is an essential part of the present invention, is attached near the inner edge of the upper window frame rubber member 13 on the outer surface of the windshield 11. As shown in FIG. 2, the windshield stain prevention member 20 is made of rubber and has an elongated base portion 21 having a triangular cross-section, and a wedge-shaped member integrally provided along the length direction of the base portion 21. The water outflow prevention part 22 is provided. The base portion 21 and the water outflow prevention portion 22 are usually integrally formed, but they may be formed separately and then joined together. The lower adhesive surface 21 a of the base portion 21 is formed according to the curved shape of the windshield 11. Since it is necessary to form the water outflow prevention portion 22 thin as described later, in order to increase the adhesion strength of the stain prevention member 20 to the windshield surface, the stain prevention member 20 and the base portion 21 having a large adhesion area are thinned. The water outflow prevention part 22 of FIG. The reason why the water outflow prevention part 22 is made of a thin wedge shape and made of rubber is that the wind out noise is prevented by easily deforming the water outflow prevention part 22 when the wind pressure is generated while the vehicle is running. This is because. Therefore, it is possible to appropriately change the shapes of the base portion 21 and the water outflow prevention portion 22 within a range in which the adhesive strength is secured and the generation of wind noise is prevented.

The windshield stain prevention member 20 has a double-sided tape attached to the adhesive surface 21a or an adhesive agent applied thereto, so that the tip of the wedge-shaped water outflow prevention portion 22 faces upward as shown in FIG. Thus, it is used by being attached to the outer surface of the windshield 11 at a position close to the inner edge of the upper window frame rubber member 13. The windshield stain prevention member 20 may be attached to a contact position with the inner edge of the upper window frame rubber member 13.

Next, the operation of the windshield stain prevention member 20 will be described. When a long time has not passed with the wax applied to the roof portion 14 of the automobile 10, when the automobile 10 is driven during the nighttime rain, the rainwater that has fallen on the roof portion 14 will be exposed to the applied wax. It melts and flows toward the surroundings. At this time, when the brake is actuated to forcibly stop the automobile 10, the rainwater in the roof portion 14 is moved by the inertial force toward the windshield 11 surface over the upper window frame rubber member 13 supporting the windshield 11. Try to leak. However, this rainwater is blocked by the wedge-shaped water outflow prevention portion 22 of the windshield stain prevention member 20 attached to the outer surface of the windshield 11 in contact with or close to the tip of the upper window frame rubber member 13. It is stopped and does not flow out to the windshield 11 surface. Therefore, since no wax coating is formed on the windshield 11 surface, the light emitted from the external lighting device does not hit the coating and cause irregular reflection and scattering. The visibility is not disturbed. Further, since the dirt prevention member 20 is made of an elastic material and the water outflow prevention portion 22 is thinly formed, the water outflow prevention portion 22 is deformed by wind pressure when the vehicle is running, so that unnecessary wind noise is generated. Is prevented from occurring.

Next, a second embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 4, the windshield stain prevention member 20 according to the second embodiment is configured by integrally molding the window frame rubber member 13 and the wedge-shaped water outflow prevention unit 22, and the water outflow prevention unit The front end of 22 is attached to the window frame rubber member 13 so that it is directed upward and forms an acute angle with the surface of the windshield 11.

Also in the windshield stain prevention member 20 according to the second embodiment configured as described above, the rainwater containing wax is wedge-shaped water outflow integrally attached to the upper window frame rubber member 13. It is blocked by the prevention part 22 and does not flow out to the windshield 11 surface. Therefore, since no wax film is formed on the windshield 11 surface, the light emitted from the external lighting device does not impinge on the film, and irregular reflection and scattering do not occur. It will not be disturbed. Further, in the windshield stain prevention member 20 according to this embodiment, since the window frame rubber member 13 and the water outflow prevention portion 22 are integrally formed, it is troublesome to attach the water outflow prevention portion 22 to the front glass 11. It is convenient because it can be omitted.
