Description

  The present invention relates to an automobile wind molding.

  A wind molding is mounted around the windshield of a car to seal the gap between the edge of the windshield and the peripheral wall of the window frame of the vehicle body. In recent years, as shown in FIG. 5 and FIG. 6 showing a 6-6 cross section thereof, a so-called design-part-less type wind molding 80 that does not cover the edge G4 of the outer surface G2 of the windshield G has come to be used. I came. Reference numeral A denotes an adhesive for fixing the window glass G to the window frame F of the vehicle body, F1 denotes a peripheral wall of the window frame F, and F2 denotes a window glass mounting surface of the window frame F.

  The window molding 80 is made of an extruded product of a deformable synthetic resin such as plastic or rubber, and has a main body 81 adhered to the vicinity G3 of the inner surface G1 of the window glass, and a window frame peripheral wall of the main body 81. A lip piece 89 is provided on the side surface 83 so as to protrude at the same height as the wind glass attachment surface 85 of the main body 81.

  The window molding 80 is adhered to the vicinity G3 of the edge of the inner surface G1 of the window glass by an adhesive B made of a double-sided adhesive tape or the like provided on the window glass adhesion surface 85, and then the window glass G At the same time, it is assembled to the window frame F of the vehicle body. As a result, the lip piece 89 comes into pressure contact with the peripheral wall F1 of the window frame F and seals the gap S between the edge of the window glass G and the peripheral wall F1 of the window frame.

  However, in the case of the conventional design-less-type window molding 80, the edge of the window glass G and the peripheral wall of the window frame are caused by variations when the window glass G is assembled or when the window frame F is assembled. The gap S with F1 is difficult to be constant, which tends to cause problems such as poor assembly work of the window molding 80 and aesthetics after the assembly, or abnormal noise generated during traveling after the assembly. For example, when the gap S is narrowed, as shown in FIG. 7, the tip 89a of the lip piece 89 protrudes outward from the peripheral wall F1 of the window frame, causing deterioration in appearance, There is a possibility that abnormal noise such as wind noise by 89 is generated. Further, since the length of the lip piece 89 is determined in anticipation of variations in the gap S, the lip piece 89 is formed short to prevent the tip 89a of the lip piece from protruding from the peripheral wall F1 of the window frame. I couldn't.

  Further, as in Patent Document 2 to be described later, in a wind molding having a design portion that includes a fitting groove into which an edge of the wind glass is inserted and the upper portion of the wind molding covers the outer peripheral surface of the windlass, the lower lip is V-shaped. In addition, when the gap between the edge of the window glass and the peripheral wall of the window frame is small, a lip is bent from the middle to cope with it. However, in this wind molding with a design part, the bending position of the lower lip can be made constant as the V-shaped bottom part, but the V-shaped bottom part has lower rigidity than the other parts. Therefore, when the gap between the edge of the window glass and the peripheral wall of the window frame becomes narrow, it is difficult to say that the lower lip is easily bent at the V-shaped bottom. Therefore, when assembling the window molding with the design portion to the window frame F, if the gap is narrow, the reaction force of the lower lip increases due to the contact between the peripheral wall of the window frame and the lower lip. There is a problem that cannot be said to be good. In addition, when the gap is small, when the window molding is assembled to the window frame F, the lower lip is bent upward by the notch at the base of the lower lip so that the tip of the lower lip is outward from the peripheral wall of the window frame. There is a problem in that the appearance tends to deteriorate due to the protrusion, and abnormal noise such as wind noise is likely to occur when the vehicle is running.

  Further, it is conceivable to apply the V-shaped lower lip to the design portion-less wind molding. However, when the gap is narrow, when the design portion-less wind molding is assembled to the window frame, the V-shaped lower lip is used. Due to the large reaction force generated in the lower lip, the following problem also occurs. In other words, the design part-less wind molding does not have the wind glass fitting groove that exists in the wind molding with the design part, and the upper part of the wind molding is adhered and fixed to the inner edge of the wind glass with double-sided adhesive tape or the like. Therefore, the fixing strength with respect to the edge of the wind glass is smaller than that of the wind molding having the design portion. Therefore, if the gap between the edge of the window glass and the peripheral wall of the window frame is small and the reaction force of the lip is large when the window molding is assembled to the window frame, the window molding is rotated by the reaction force of the lip. A force is applied, and the wind molding is easily peeled off from the inner surface of the wind glass, or the wind molding is inclined to rise from the gap due to a change with time after the wind molding is assembled.

  The present invention has been made in view of the above points, and it is possible to reduce the gap between the edge of the window glass and the peripheral wall of the window frame caused by variations when the window glass is assembled or when the window frame is assembled. If the gap is narrow enough, the wind molding can be prevented from tilting and lifting from the gap. Furthermore, the lip piece protrudes from the peripheral wall of the window frame, resulting in a loss of aesthetics and wind cuts when driving. The purpose is to provide a wind molding that can prevent sound generation.

  The present invention is applied to an automotive wind molding that is adhered to the vicinity of the edge of the inner surface of the window glass and seals between the edge of the window glass and the peripheral wall of the window frame of the vehicle body, and is adhered to the vicinity of the edge of the inner surface of the window glass. And a lip piece projecting from the side face of the window frame peripheral wall of the main body part, the lip piece having a thin bent part between a root and a tip, and a base side from the bent part Is inclined downward from the side surface of the peripheral wall of the window frame, and is inclined upward on the tip side from the bent portion. In the present invention, “downward” has the same meaning as “in the direction opposite to the wind glass attachment surface of the automobile wind molding”, while “upward” means “wind glass attachment surface side”. Is equivalent to "in the direction of".

  According to the wind molding of the present invention, the lip piece is provided with a thin bent portion between the root and the tip, and is inclined downward from the side surface of the window frame peripheral wall with respect to the root side with respect to the bent portion, more than the bent portion. Since the tip side is inclined upward, there is a gap between the edge of the window glass and the peripheral wall of the window frame due to variations when the window glass is assembled or when the window frame is assembled. Even if it becomes narrow, it is possible to fold the lip piece with a thin bent portion to prevent the tip of the lip piece from protruding outward from the peripheral wall of the window frame, and to improve the aesthetics at the edge of the window glass. At the same time, it is possible to suppress the generation of wind noise due to the lip piece when the vehicle is running.

  Furthermore, in the present invention, since there is no notch at the base of the lip piece, when the window molding is assembled to the window frame, the lip piece contacts the peripheral wall of the window frame and the entire lip piece bends upward from the base. Wind molding caused by the reaction force when the entire lip piece bends upward from the root, and the lip piece can be securely folded at the bent portion located between the root and the tip of the lip piece. As a result, it is possible to effectively prevent the lowering of assembling workability and the tilting and lifting during or after the wind molding.

  In addition, in the present invention, even if the lip piece is designed to be long in anticipation of the gap being widened, when the gap is narrowed, the tip of the lip piece is folded by the folding of the lip piece. Can be prevented from projecting outward from the peripheral wall of the window, so that it is possible to easily cope with the variation in the assembling of the window glass and the width of the gap caused by the variation in assembling the window frame, It is possible to cope with the wide and narrow gaps due to the difference in vehicle type with one type of wind molding.

FIG. 4 is a sectional view showing an assembled state of the wind molding according to the embodiment.

  A wind molding 10 shown in FIG. 1 is a design-less type, and as shown in (2-A) and (2-B) of FIG. Is attached to the window frame F of the vehicle body together with the window glass G, and by the assembly, the gap S between the periphery of the window glass G and the peripheral wall F1 of the window frame F of the vehicle body is sealed. . When assembled to the window frame F, an adhesive A for fixing the window glass is provided in advance on the window glass mounting surface F2 of the window frame F facing the edge vicinity G3 of the inner surface G1 of the window glass.

  The window molding 10 is made of an extrusion-molded product such as synthetic resin, and protrudes from a main body portion 11 adhered to an edge vicinity G3 of the inner surface G1 of the window glass, and a window frame peripheral wall side surface 16 in the main body portion 11. And a lip piece 19 that press-contacts the peripheral wall F1 of the window frame F of the vehicle body at the time of assembly.

  The main body 11 includes a head 12 having a wind glass attachment surface 15 on a side facing the inner surface G1 of the wind glass, and a back surface side of the head 12 (the side opposite to the wind glass attachment surface 15). And a leg portion 13 formed on the bottom. The leg portion 13 of this embodiment is formed at a substantially right angle from the edge of the head portion 12 on the side of the window frame peripheral wall, and the main body portion 11 is formed in a substantially inverted L-shaped cross section by the head portion 12 and the leg portion 13. Is formed. Note that the adhesive material B made of a double-sided adhesive tape or the like provided on the wind glass adhesive surface 15 is usually provided after the molding of the window molding 10.

  The lip piece 19 has elasticity, and is provided with a thin bent portion 19a between the root 19d and the tip 19e of the lip piece 19, and the side of the window frame peripheral wall side of the root side 19b with respect to the bent portion 19a. 16 is formed so as to incline downward L. On the other hand, the distal end side 19c of the bent portion 19a is inclined upward U. When the window molding 10 is assembled to the window frame F, the root side 19b is inclined downward from the window frame peripheral wall side surface 16 while the tip end 19c is inclined upward. The base side 19b and the tip end side 19c of the lip piece 19 are pushed and deformed toward the leg portion 13 side of the main body 11, and the lip piece 19 is easily folded using the bent portion 19a as a bending point.

  The thin shape of the bent portion 19a may be any shape as long as the rigidity of the lip piece 19 is reduced by the bent portion 19a so that the lip piece 19 can be easily folded by the bent portion 19a. As appropriate. The concave shape or notch may be formed on either the upper surface side or the lower surface side of the lip piece 19. The bent portion 19a is positioned away from the window frame peripheral wall side surface 16, and is set at an appropriate position between the root 19d and the tip 19e of the lip piece 19. In the illustrated example, the base 19b is shortened, and the bent portion 19a is provided at a position close to the window frame peripheral wall side 16.

  The tip side 19c of the lip piece 19 is preferably arcuately bulging upward. With this shape, when the window molding 10 is assembled to the window frame F, the tip of the lip piece 19 can be securely adhered to the peripheral wall F1 of the window frame F, and the tip 19e of the lip piece 19 is secured. Can be prevented from deteriorating due to the separation from the peripheral wall F1 of the window frame.

  When the window molding 10 is attached to an edge G3 of the inner surface G1 of the window glass G with an adhesive B such as a double-sided adhesive tape, and then assembled to the window frame F of the vehicle body together with the window glass G, 2 (2-A) and (2-B), even if the gap S between the peripheral edge of the window glass G and the peripheral wall F1 of the window frame F of the vehicle body is wide, the tip of the lip piece 19 When the side 19c abuts on the peripheral wall F1 of the window frame F and is pushed toward the main body 11 side, the lip piece 19 is folded using the thin bent portion 19a as a folding point, and the gap S is changed depending on the degree of folding. It can cope with wide and narrow. Further, even when the gap S is narrow, the tip of the lip piece 19 can be prevented from protruding outward from the peripheral wall F1 of the window frame F.

  In the first embodiment, the root side 19b of the lip piece 19 is set to be short. However, the root side 191b of the lip piece 191 is long as in the wind molding 10A of the second embodiment shown in FIGS. May be set.
