Description

  The present invention relates to an automobile wind molding.

  A wind molding is installed around the windshield of an automobile to seal a 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. 9 and FIG. 10 showing a 10-10 cross section thereof, a so-called design part-less type wind molding 80 which 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 is an adhesive for fixing the window glass G to the window frame F of the vehicle body, F1 is a peripheral wall of the window frame, F2 is a window glass mounting surface of the window frame F facing the edge G3 of the inner surface G1 of the window glass G. is there.

  The window molding 80 is made of a deformable synthetic resin such as plastic or rubber, and projects into a main body portion 81 disposed on an edge G3 of the inner surface G1 of the window glass, and a window frame peripheral wall side portion 83 in the main body portion 81. A provided lip piece 89 is provided. The main body 81 is provided with a window glass side adhesive surface 85 on the side facing the edge G3 of the inner surface G1 of the window glass.

  The window molding 80 is bonded to the edge G3 of the inner surface G1 of the window glass by an adhesive layer B made of a double-sided adhesive tape or the like provided on the window glass side bonding surface 85. It is assembled to the window frame F. 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.

  At the time of the assembling, an adhesive A for fixing the window glass is previously disposed on the window glass mounting surface F2 of the window frame F, and the adhesive A is attached to the inner surface G1 of the window glass and the window molding 80 at the time of the assembling. The main body 81 abuts both the window glass inner side surface. The window glass G is fixed to the window frame F by allowing the adhesive A to harden in that state for a predetermined time. At this time, since it takes time to cure the adhesive A, it is necessary to hold the wind molding 80 in a correct posture until the adhesive A is completely cured.

  However, until the adhesive A is completely cured, in the wind molding 80, the lip piece 89 is bent in pressure contact with the peripheral wall F1 of the window frame F. A restoring force is applied to the main body 81. As shown in FIG. 11, the restoring force of the lip piece 89 is such that the window glass inner side surface 85 of the window glass side adhesive surface 85 (the lip A force Q1 in a direction away from the inner surface G1 of the window glass f acts on the main body 81. Therefore, until the adhesive A is completely cured, the main body portion 81 of the wind molding 80 is inclined and the sealing performance of the gap S is impaired, or the bonding position of the wind molding 80 to the wind glass G is changed. It tends to occur that the aesthetic appearance of the peripheral edge of the window glass G is lost.

JP 2004-66983 A (paragraph 0005, FIG. 5)

  The present invention has been made in view of the above points, and can provide a wind molding that can be fixed in a correct posture and position when assembled to a window frame, and that is less likely to cause a sealing failure and a decrease in the appearance of the window glass. With the goal.

  The invention of claim 1 is an automotive wind molding that is bonded to an edge of an inner surface of a window glass and is assembled to a window frame of a vehicle body together with the window glass, and a main body portion disposed at an edge of the inner surface of the window glass; A lip piece that comes into contact with the peripheral wall of the window frame of the vehicle body at the time of assembling, the windshield side adhesive surface provided on the side facing the edge of the inner surface of the windglass on the main body, and the windglass side adhesive A posture holding projection formed on the opposite side of the surface, and the tip of the posture holding projection is located inside the window glass from the window frame peripheral wall side end portion of the main body portion of the window glass side adhesive surface. Formed so as to be in contact with or substantially in contact with the window glass mounting surface of the window frame facing the edge of the inner surface of the window glass at the time of assembly. It is characterized in that is.

  According to a second aspect of the present invention, in the first aspect, the posture holding protrusion is formed on a free end side of an elastic piece extending from the main body.

  According to the invention of claim 1, when the window molding is bonded to the inner edge of the window glass and assembled to the window frame together with the window glass, the lip piece of the window molding abuts on the peripheral wall of the window frame and bends, The restoring force of the lip piece due to the bending acts. The restoring force of the lip piece is the inward side of the window glass on the window glass side adhesive surface of the window molding, with the end of the window frame peripheral wall side of the main body as the fulcrum (opposite to the window frame peripheral wall side end of the main body) Side) acts as a rotational force in a direction away from the inner surface of the window glass and acts on the main body portion to try to incline the main body portion. However, the main body portion is inclined in a direction away from the inner surface of the window glass (the center side of the window glass, that is, the side opposite to the window frame peripheral wall end of the main body portion) of the window glass side adhesive surface ( The tip of the posture-holding protrusion formed on the side of the main body opposite to the window glass side adhesive surface is in contact with the window glass mounting surface of the window frame facing the edge of the inner surface of the window glass. , Preventing the tilt of the main body. Therefore, since the inclination of the window molding can be suppressed until the window glass fixing adhesive disposed between the window frame and the inner surface of the window glass is completely cured, the window molding is fixed in the correct posture and position. It is possible to make it difficult to cause a sealing failure and a decrease in the appearance of the peripheral edge of the windshield.

  According to the second aspect of the present invention, the posture holding projection is formed on the free end side of the elastic piece extending from the main body portion, so that the edge of the inner surface of the window glass and the window can be reduced due to variations in work during assembly. Even if the interval between the window glass mounting surfaces of the frame is narrower than the set interval, the elastic piece is deformed when the posture holding projection comes into contact with the window glass mounting surface of the window frame, and the posture holding projection is displaced to the wind glass side. Therefore, it is possible to prevent the window molding from being arranged between the edge of the inner surface of the window glass and the window glass mounting surface of the window frame.

  The window molding 10A according to the first embodiment shown in FIGS. 1 and 2 is bonded to the edge G3 of the inner surface G1 of the window glass G and assembled to the window frame F of the vehicle body together with the window glass G. A 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. At the time of assembly, 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 G3 of the inner surface G1 of the window glass.

  The window molding 10A is made of synthetic resin or the like by extrusion molding or the like. The window molding 10A is formed on the main body 11 disposed on the edge G3 of the inner surface G1 of the window glass and the window frame peripheral wall side portion 13 in the main body 11. And a lip piece 19 that protrudes and comes into contact with the peripheral wall F1 of the window frame F of the vehicle body when assembled. The lip piece 19 has elasticity.

  The main body 11 has a window glass side adhesive surface 15 provided on the side facing the inner surface G1 of the window glass, and a posture holding projection 18 formed on a side 16 opposite to the window glass side adhesive surface 15. And have. The main body 11 of the present embodiment includes a head portion 11a substantially parallel to the edge G3 of the inner surface G1 of the window glass, and a leg portion 11b formed substantially at right angles from the end of the head portion 11a to the back side of the head portion 11a. The surface of the head portion 11a is the window glass side adhesive surface 15, and the posture holding projection 18 is on the opposite side of the leg portion 11b from the head portion 11a. Is formed. Note that an adhesive layer B made of a double-sided adhesive tape or the like is provided on the window glass side adhesive surface 15 as an adhesive for the window molding 10A to the window glass G. The adhesive layer B is usually provided after the molding of the window molding 10A.

  The posture holding projection 18 has a tip 18a positioned on the inner side (the center side of the window glass G) K of the window glass G with respect to the window frame peripheral wall side edge 15a of the main body of the window glass side adhesive surface 15. In addition, the window glass F is formed so as to contact or substantially contact the window glass mounting surface F2 of the window frame F facing the edge G3 of the inner surface G1 of the window glass during the assembly. The distance between the tip 18a of the posture holding projection 18 and the window glass mounting surface F2 of the window frame F is preferably 0.5 mm or less. With this configuration, the lip piece 19 is bent in contact with the peripheral wall F1 of the window frame at the time of assembly, and the window frame on the window glass side adhesive surface 15 is restored by the restoring force of the lip piece 19 due to the bending. With the peripheral wall side end 15a as a fulcrum, the wind glass inner side K of the window glass side adhesive surface 15 (the center side of the window glass G, that is, the side opposite to the window frame peripheral wall side end 15a) is the inner surface of the window glass. Even if the main body 11 is inclined like the main body 81 of the wind molding 80 shown in FIG. In order to prevent tilting (rotation) of the main body 11 in contact with the surface F2, the wind molding 10A is placed in the correct posture and position until the adhesive A is completely cured. In can be maintained.

  A more preferable position of the tip 18a of the posture holding projection 18 is the inner side of the window glass G (the center of the window glass G) than the position C that is 1/2 the width W of the window glass side adhesive surface 15. Side, that is, the side opposite to the window frame peripheral wall side end portion 15a). With this configuration, the force (moment) generated when the posture maintaining projection 18 comes into contact with the window glass mounting surface F2 of the window frame F is further increased, and the body portion 11 is inclined by the restoring force of the lip piece 19. (Rotation) can be suppressed more effectively.

  Hereinafter, the window moldings 10B to 10D of the second to fourth embodiments illustrated in FIGS. 3 to 8 will be described. In addition, regarding the window moldings 10B to 10D of the second to fourth embodiments, parts having the same names as the respective parts in the window molding 10A of the first embodiment have the same reference numerals for easy understanding, and Detailed description is omitted in order to prevent duplication with the description in the wind molding 10A of the first embodiment.

  The window molding 10B according to the second embodiment shown in FIGS. 3 and 4 is configured such that the tip end 18a side of the posture holding projection 18 is opposite to the window frame peripheral wall side end 15a of the main body 11 of the window glass side adhesive surface 15. That is, this is an example in which the window glass is inclined toward the inner side K (center side), and the other configuration is the same as that of the window molding 10A of the first embodiment.

  The window molding 10 </ b> C of the third embodiment shown in FIGS. 5 and 6 is an example in which the posture holding projection 18 is formed on the free end side 17 a of the elastic piece 17 extending from the main body 11. Others are the same as the window molding 10A of 1st Embodiment. In the illustrated example, the main body portion 11 is positioned on the opposite side of the window glass side adhesive surface 15 and the window glass side adhesive surface 15 is opposite to the window frame peripheral wall side end portion 15a on the main body portion 11. The elastic piece 17 extends toward the window glass inner side K (the center side of the window glass G), and a posture holding projection 18 is formed on the free end side 17 a of the elastic piece 17.

  The posture holding projection 18 is formed on the free end side 17a of the elastic piece 17, so that when the window glass G and the window molding 10C are assembled to the window frame F, the window glass inner surface G1 is formed due to variations in work. Even if the interval between the edge G3 and the window glass mounting surface F2 of the window frame is narrower than the set interval, the elastic piece 17 is deformed when the posture holding projection 18 contacts the window glass mounting surface F2 of the window frame. Since the attitude holding projection 18 is displaced toward the wind glass G, it is possible to prevent the wind molding 10C from being disposed between the edge G3 of the window glass inner surface G1 and the window glass mounting surface F2 of the window frame.

  The window molding 10D of the fourth embodiment shown in FIG. 7 and FIG. 8 has a main body portion 11 consisting only of a portion corresponding to the head portion 11a in the window molding 10C of the third embodiment, and no leg portion 11b. The elastic piece 17 extends in a direction opposite to the window glass side adhesive surface 15 from a side portion 14 opposite to the window frame peripheral wall side portion 13 of the main body portion 11. ing. The free end side 17 a of the elastic piece 17 is bent in a substantially L shape in a direction substantially parallel to the window glass side adhesive surface 15.

  Similarly to the window molding 10C of the third embodiment, the window molding 10D of the fourth embodiment also has an inner surface of the window glass due to variations in work when the window glass G and the window molding 10C are assembled to the window frame F. Even when the gap between the edge G3 of G1 and the window glass mounting surface F2 of the window frame is narrower than the set interval, the elastic piece 17 is deformed when the posture holding projection 18 comes into contact with the window glass mounting surface F2 of the window frame. Then, since the attitude maintaining projection 18 is displaced toward the wind glass G, it is possible to prevent the wind molding 10C from being disposed between the edge G3 of the window glass inner surface G1 and the window glass mounting surface F2 of the window frame.

  In the present invention, the whole of the window molding does not have to be made of the same material. For example, the main body and the lip piece may be made of different materials.
