Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the case of the above conventional structure, it is necessary to pre-form the substantially triangular prism-shaped snow accumulation prevention member Q, and the shape of the step portion D varies widely depending on the vehicle type. Therefore, a plurality of snow accumulation prevention members Q must be prepared according to various vehicles, and as a result, the snow accumulation prevention structure becomes complicated, the manufacturing cost becomes high, the storage of the snow accumulation prevention member Q also becomes troublesome, and there is a disadvantage that it may reduce the convenience and economy of use.

Means for Solving the Problems

[0006] The present invention aims to solve these problems, and the invention described in claim 1 of this invention is a vehicle snow retention structure characterized by having a stepped portion between the vehicle's windshield and an adjacent vehicle component, and preventing snow from accumulating on the side of the windshield due to the wiping action of the wiper by the stepped portion, wherein a flexible, transparent snow retention prevention sheet is attached to the windshield while straddling the space between the windshield and the adjacent vehicle component.

[0007] Furthermore, the invention described in claim 2 is characterized in that the snow retention prevention sheet is made of a synthetic resin having a low coefficient of friction and a slippery surface, and the invention described in claim 3 is characterized in that the snow retention prevention sheet is made of a fluororesin. [Effects of the Invention]

[0008] As described above, in the invention described in claim 1, a flexible, transparent snow retention prevention sheet is attached across the space between the windshield and the adjacent vehicle component. This allows the snow retention prevention sheet to cover the step between the windshield and the adjacent vehicle component, thereby eliminating the step. The snow retention prevention sheet prevents snow from accumulating on the sides of the vehicle's windshield due to the wiper's wiping action. Furthermore, the wiper's wiping action helps to push the snow outwards from the sides of the windshield, further preventing snow from accumulating on the sides of the windshield. This prevents snow accumulation from obstructing the view through the windshield, improving the safety of vehicle operation. Additionally, since only a snow retention prevention sheet sized to fit the shape of the step needs to be attached, the snow retention prevention structure can be simplified, manufacturing costs can be reduced, and storage of the snow retention prevention sheet becomes easier, improving convenience and economic efficiency.

[0009] Furthermore, in the invention described in claim 2, the snow retention prevention sheet is made of a synthetic resin with a low coefficient of friction and a slippery surface, so the wiper's wiping action can help push the snow on the sides of the windshield outwards, and the snow retention prevention sheet can help the snow slide off the sides of the windshield, thus further preventing snow from accumulating on the sides of the windshield, thereby preventing the windshield from obstructing the view due to snow accumulation. Furthermore, in the invention described in claim 3, the snow retention prevention sheet is made of a fluororesin, so the low coefficient of friction makes the surface of the snow retention prevention sheet slippery, further helping the snow slide off the sides of the windshield, thus preventing snow from accumulating on the sides of the windshield, thus preventing the windshield from obstructing the view due to snow accumulation, thus maintaining good visibility and further enhancing the safety of vehicle driving.

[Figure 3] This is a partial cross-sectional view of a first embodiment of the present invention. [Figure 4] This is a partially enlarged front view of a first embodiment of the present invention. [Figure 5] This is a partially enlarged front view of a second embodiment of the present invention. [Figure 6] This is a partial cross-sectional view of a conventional structure. [Figure 7] This is a partially enlarged front view of the conventional structure. [Modes for carrying out the invention]

[0011] Figures 1 to 5 show examples of embodiments of the present invention, with Figures 1 to 4 being the first embodiment and Figure 5 being the second embodiment.

[0012] In the first embodiment shown in Figures 1 to 4, a step portion D exists between the windshield G of vehicle C and an adjacent vehicle component T, and the structure prevents snow S from accumulating on the side of the windshield G of vehicle C due to the wiping action of the wiper W by the step portion D. In this case, a window molding M made of synthetic resin or rubber is interposed between the windshield G and the front pillar P, and a step portion D is formed between the windshield G and the window molding M. A flexible transparent snow accumulation prevention sheet F is attached to span across this space between the windshield G and the adjacent vehicle component T, in this case between the windshield G and the window molding M and front pillar P as vehicle components T, or between the windshield G and the window molding M as vehicle components T. The snow accumulation prevention sheet F must be a transparent sheet with a visible light transmittance of 70% or more (Ministry of Land, Infrastructure, Transport and Tourism, Article 195, Paragraph 3, Items 1 and 2).

[0013] In this case, the snow retention prevention sheet F is made of a synthetic resin with a low coefficient of friction and a slippery surface.

[0014] In this case, the snow retention prevention sheet F is made of fluororesin. For example, amorphous fluororesin has a visible light transmittance of approximately 88% to 95%, excellent weather resistance and chemical resistance, and is a highly transparent synthetic resin. In addition to fluororesin, acrylic resin may also be used. Acrylic resin has a visible light transmittance of approximately 92% to 94%, making it a highly transparent synthetic resin. Other transparent synthetic resins such as polyethylene resin, polyacetal resin, nylon resin, and polycarbonate may also be used.

[0015] Furthermore, in this case, as shown in Figure 2, the size of the snow retention prevention sheet F is formed to be longer than the vertical wiping width B of the wiping range R of the wiper W.

[0016] Also, in this case, an adhesive layer (not shown) is formed on the back surface of the snow accumulation prevention sheet F, a release sheet is provided on the adhesive layer, and the release sheet is peeled off and the snow accumulation prevention sheet F is attached by the adhesive layer. Note that the snow accumulation prevention sheet F may be attached by a double-sided adhesive tape.

[0017] Also, a winding tape (not shown) for winding up the snow accumulation prevention sheet F is prepared, or a wide snow accumulation prevention sheet F is prepared, and the winding tape or the wide snow accumulation prevention sheet F is cut to a size corresponding to the step portion D, and the cut snow accumulation prevention sheet F can be attached in a state straddling between the front glass G and the vehicle component T adjacent to the front glass G.

[0018] Since the first exemplary embodiment has the above-described configuration, as shown in FIGS. 1, 2, 3, and 4, a flexible transparent snow accumulation prevention sheet F is attached in a state straddling between the vehicle component T adjacent to the front glass G, in this case, the window molding M and the front pillar P as the front glass G and the vehicle component T. Therefore, the step portion D existing between the front glass G and the vehicle component T adjacent to the front glass G can be covered by the snow accumulation prevention sheet F, whereby the step portion D can be eliminated, and the snow accumulation prevention sheet F can prevent snow S from accumulating on the side portion of the front glass G of the vehicle C accompanying the wiping operation of the wiper W. Further, the wiping operation of the wiper W can promote the outward pushing of the snow S on the side portion of the front glass G, further preventing the snow S from accumulating on the side portion of the front glass G, preventing the snow S from obstructing the visibility of the front glass G, improving the safety of vehicle driving, and only attaching the snow accumulation prevention sheet F having a size corresponding to the shape of the step portion D, the snow accumulation prevention structure can be simplified, the manufacturing cost can be reduced, the storage of the snow accumulation prevention sheet F is facilitated, and the convenience and economy of use can be improved.

[0019] Also, in this case, since the snow retention prevention sheet F has a small coefficient of friction and is made of a synthetic resin with a slippery surface, the wiping operation of the wiper W can assist in pushing the snow S on the side of the front glass G outward, and the snow retention prevention sheet F can assist in the sliding down of the snow S on the side of the front glass G, further preventing the retention of the snow S on the side of the front glass G. Only in this way can it prevent the obstruction of the view of the front glass G due to the retention of the snow S. Also, in this case, since the snow retention prevention sheet F is made of a fluororesin, the surface of the snow retention prevention sheet F becomes slippery due to the small coefficient of friction, and it can further assist in the sliding down of the snow S on the side of the front glass G, preventing the retention of the snow S on the side of the front glass G. Only in this way can it prevent the obstruction of the view of the front glass G due to the retention of the snow S, maintain a good view, and further enhance the safety of vehicle driving.

[0020] In the second exemplary embodiment of FIG. 5, in this case, it is an exemplary embodiment in which the present invention is applied to a vehicle C having a so-called seamless structure that does not include the window molding M. That is, a front pillar P is arranged as a vehicle component T adjacent to the front glass G, a step portion D is formed between the front glass G and the front pillar P, and a flexible transparent snow retention prevention sheet F is pasted in a state straddling between the front glass G and the front pillar P as the vehicle component T adjacent to the front glass G.

[0021] In this second embodiment, a flexible, transparent snow retention prevention sheet F is attached across the front pillar P, which is a vehicle component T adjacent to the windshield G. The snow retention prevention sheet F can cover the step portion D that exists between the windshield G and the front pillar P, which is a vehicle component T adjacent to the windshield G. This eliminates the step portion D, and the snow retention prevention sheet F prevents snow S from accumulating on the side of the windshield G of the vehicle C due to the wiping operation of the wiper W. This method facilitates the outward pushing of snow S at the side of the windshield G, further prevents snow S from accumulating at the side of the windshield G, prevents snow S from obstructing the view through the windshield G, enhances the safety of vehicle operation, simplifies the snow accumulation prevention structure by simply attaching a snow accumulation prevention sheet F sized to fit the shape of the stepped section D, reduces manufacturing costs, makes storage of the snow accumulation prevention sheet F easier, improves convenience and economy of use, and provides the same effects as the first embodiment example described above.

[0022] Furthermore, this invention is not limited to the above-described embodiments, and the structure and form of the snow retention prevention sheet F, wiper W, vehicle component T, and windshield G can be modified as appropriate in the design.

[0023] In summary, the intended objectives can be fully achieved. [Explanation of Symbols]
