JP3009418U - Raindrop prevention device for automobile windshield - Google Patents

Abstract

(57) [Summary] [Purpose] In a raindrop prevention device that prevents raindrops from the body roof of a vehicle to the windshield, it has both the function of dampening water and the rigidity of retaining its shape. [Structure] The raindrop prevention apparatus main body 1 has a hollow triangular cross-section, and the angle between the surfaces 1a and 1b is greater than 90 degrees.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a raindrop prevention device for a windshield of an automobile, which is installed at a boundary between an automobile windshield and a body roof portion and prevents raindrop from the body roof portion to the windshield.

[0002]

[Prior art]

 Most conventional automobiles are connected smoothly from the windshield to the body roof in order to reduce air resistance during driving. As a result, rainwater flows down from the body roof to the windshield, so the wax applied to the body roof flows to the windshield, creating an oil film. In order to prevent this, the concave water-conducting grooves, such as the actual opening No. 61-48853 and the actual opening No. 01-161841, which are attached at the boundary between the front glass and the body roof, and the actual opening No. 03-15240 A raindrop prevention device with a V-shaped cross section has been devised.

However, the raindrop prevention device (concave water guiding groove) needs to be fixed in close contact with a curved body roof, and a flexible material is required. On the other hand, the part that blocks rainwater must be tall enough to block the water that flows from the body roof, and it must be rigid enough to maintain its shape in various environments for a long period of time. Becomes

[0004]

[Problems to be solved by the device]

 The problem to be solved is that in the concave water guiding groove such as the actual exploitation Sho 61-48853 and the actual exploitation 01-16 1841, and the raindrop prevention device with the V-shaped cross section of the actual exploitation 03-15240, The point is that it is not possible to achieve both the function of damaging water and the rigidity of retaining its shape.

[0005]

According to the present invention, in the raindrop prevention device, a cross-sectional shape thereof is a hollow triangle, and a surface of the hollow triangle which is adhered to a body roof and a surface for damming water. It is characterized in that the included angle between and is greater than 90 degrees.

[0006]

[Action]

 With the above configuration, the hollow triangular cross-sectional shape is irreversible, resulting in weight reduction and material cost reduction, and the high rigidity achieved by this cross-sectional shape increases the height required to dampen the water of the raindrop prevention device. Can be realized. In other words, it is possible to achieve both the function of damming water and the rigidity of retaining its shape. Further, when the vehicle is being braked, water on the body roof may violently hit the raindrop prevention device according to the present invention. In such a case, by setting the included angle between the surface to be bonded to the body roof and the surface for blocking water to be larger than 90 degrees, the water can be firmly blocked without passing over the raindrop prevention device according to the present invention. .

【Example】

 The attached drawings illustrate one embodiment of the raindrop prevention apparatus according to the present invention. FIG. 1 is a plan view of a raindrop prevention apparatus according to the present invention, and FIG. 2 is a sectional view taken along line AA of the raindrop prevention apparatus according to the present invention. 1 is the main body of the raindrop prevention device, 2 is the body roof of the automobile, and 3 is the windshield of the automobile.

The raindrop prevention device body 1 is bonded to the body roof 2 along the boundary between the body roof 2 and the windshield 3. It is easy to use the double-sided tape 4 as the bonding method.

Further, as shown in FIG. 2, the raindrop prevention device main body 1 has a hollow triangular cross section, and the surface to be bonded to the body roof 2 is a surface 1a, and the surface for damming water is a surface 1b. The included angle of 1b is 100 degrees. Therefore, even when the water on the body roof 2 vigorously hits the surface 1b during braking of the vehicle, the water does not get over the raindrop prevention device main body 1 and can firmly dampen the water.

Further, this shape can be molded at low cost with a synthetic resin having flexibility.

[0011]

[Effect of device]

 As described above, the raindrop prevention apparatus according to the present invention can have both a function of damming water and a rigidity of retaining the shape because of its cross-sectional shape, and it is easy and inexpensive for various vehicles. Can be attached to the front windshield to prevent poor visibility of the windshield due to rain.
