  By the way, in order to further improve the above-described performance required for the roof molding, the following points are listed as examination subjects. (1) If the elastically deformed portion is thickened or the hardness of the material forming the locking piece is increased so that the roof molding is not easily removed from the roof groove, the resilience of the locking piece may increase excessively. There is. As a result, although it becomes difficult for the roof molding to come out of the roof groove, there is a possibility that an excessive force is required when the roof molding is attached to the roof groove. (2) On the other hand, if the elastic deformation part is made thin or the hardness of the material forming the locking piece is lowered in order to make it easy to attach the roof molding to the roof groove, the elastic force of the locking piece becomes excessive. May decrease. As a result, although it becomes easy to attach the roof molding to the roof groove, there is a possibility that the roof molding may easily come off from the roof groove after the installation.

  Accordingly, the present invention has been created to solve the above-described problems, and an object of the present invention is to provide a vehicle roof molding that is easy to be mounted on the roof groove of the vehicle body and that is difficult to come off from the roof groove after mounting. is there.

The lip portion 65 has a main body portion 68 made of an elastic polymer material, and a laminated portion 70 made of an elastic polymer material having a lower hardness than the elastic polymer material forming the main body portion 68. When the roof molding 50 is mounted on the roof groove 32, the laminated portion 70 is at least a part of the surface layer portion that is a surface layer portion of the lip portion 65 and contacts the side wall portion 38 of the roof groove 32 (preferably on the side wall portion 38. All of the surface layer portions that can be in contact with each other) are formed. In the present embodiment, as shown in FIG. 3, the surface layer portion of the lip portion 65 in the region extending from the tip portion of the lip 65 to the bent portion 72 described later is constituted by the laminated portion 70.
As shown in FIG. 3, the distance a between the tip portions of the lip portions 65 and 65 in the natural state (the state where the roof molding 50 is not attached to the roof groove 32) is the distance b in the groove width direction of the roof groove 32. (That is, in a state where the roof molding 50 is mounted in the roof groove 32, the portion where the lip portion 65 abuts against the side wall portion 26 of the center roof panel 24 and the portion where the lip portion 65 abuts against the side wall portion 30 of the side roof panel 28 The lips 65 are formed so as to be longer than the distance between the lips 65 and 65.
In the present embodiment, both the lip portions 65 and 65 have the laminated portion 70, but at least one of the lip portions 65 and 65 only needs to have the laminated portion 70.

The elastic polymer material forming the main body 68 is a polyolefin-based thermoplastic elastomer having a durometer hardness of Type A according to JIS K7215 of 60 ° or more (usually about 60 ° to 100 °, for example, about 70 ° to 90 °). Examples thereof include elastic rubber materials such as vulcanized rubber mainly composed of (TPO), polyvinyl chloride (PVC), and ethylene-propylene-diene rubber (EPDM). In the present embodiment, the head portion 55 and the leg portion 60 are integrally formed from the same material as the main body portion 68.
Examples of the elastic polymer material that forms the laminated portion 70 include an elastic polymer material that has a lower hardness than the elastic polymer material that forms the main body portion 68. Preferably, an elastic rubber such as vulcanized rubber mainly composed of TPO, PVC, EPDM having a durometer hardness of 50 ° or less (usually about 20 ° to 50 °, for example, about 30 ° to 40 °) according to JIS K7215. Materials and the like.

The static friction coefficient between the laminated portion 70 and the side wall portion 38 of the roof groove 32 is larger than the static friction coefficient between the main body portion 68 and the side wall portion 38 of the roof groove 32, and the laminated portion 70 and the roof groove 32. The dynamic friction coefficient between the side wall portion 38 and the side wall portion 38 is preferably larger than the dynamic friction coefficient between the main body portion 68 and the side wall portion 38 of the roof groove 32.
Furthermore, the dynamic friction coefficient between the laminated portion 70 and the side wall portion 38 of the roof groove 32 is preferably smaller than the static friction coefficient between the laminated portion 70 and the side wall portion 38 of the roof groove 32.

  As shown in FIGS. 2 and 3, in the present embodiment, bent portions 72 and 72 are formed in the lip portions 65 and 65, respectively. As shown in FIG. 4, when the roof molding 50 is mounted in the roof groove 32, the lip portions 65, 65 are bent at the bent portions 72, 72, and the tip portion of the lip portion 65 is displaced toward the head portion 55. (In the direction of arrow X in FIG. 4). In the present embodiment, the bent portions 72 and 72 are formed in the lip portions 65 and 65, respectively, but it is sufficient that the bent portions 72 and 72 are formed in at least one of the lip portions 65 and 65. In this embodiment, one bent portion 72 is formed in one lip portion 65, but a plurality of (for example, two or more) bent portions may be formed.

As shown in FIG. 3, the bent portion 72 according to the present embodiment is configured by a soft portion 74 made of an elastic polymer material in which at least the surface layer portion on the side facing the bottom wall portion 36 of the roof groove 32 forms a laminated portion 70. Has been. When the surface layer portion of the bent portion 72 is thus formed by the soft portion 74 made of an elastic polymer material having a lower hardness than the elastic polymer material forming the main body portion 68, as shown in FIG. When a force in the head direction (the direction of arrow X in FIG. 4) is applied to the distal end portion of 65, the lip portions 65 and 65 are configured by the bent portions 72, and the lip portion is constituted only by the main body portion. Bends more easily than in the case.
In addition, the soft portion 74 is integrally connected to the laminated portion 70. Furthermore, in this embodiment, since the thickness of the soft part 74 is formed thicker than the thickness of the lamination | stacking part 70, this lip | rip part 65,65 is ensured, ensuring the rigidity of the front-end | tip part of the lip | rip part 65,65. Can be easily bent at the bent portions 72, 72.

Next, functions (actions and effects) of the roof molding 50 according to the present embodiment will be described in detail with reference to FIGS.
As shown in FIG. 4, a distance a (see FIG. 3) between the tip portions of the lip portions 65, 65 formed of an elastic polymer material is a distance c in the groove width direction of the roof groove 32 (that is, the center roof). When the roof molding 50 is mounted in the roof groove 32, the lip portions 65, 65 are not longer than the distance between the side wall portion 26 of the panel 24 and the side wall portion 30 of the side roof panel 28. It abuts on the side walls 38, 38 and deforms in the direction of arrow X in FIG. That is, the force in the direction of the bottom wall portion 36 of the roof groove 32 is further applied to the roof molding 50 with the lip portion 65 in contact with the vicinity of the upper end of the side wall portion 38 of the roof groove 32 (the opposite end of the bottom wall portion 36). Therefore, the tip portion of the lip portion 65 is displaced toward the head portion 55 (the direction of the arrow X in FIG. 4). At this time, since the laminated portion 70 is formed of an elastic polymer material having a lower hardness than the main body portion 68, the surface layer portion of the lip portion 65 is compared with the lip portion formed of the elastic polymer material forming the main body portion 68. Thus, the lip portion 65 can be deformed with a smaller force. Further, since the lip portion 65 includes a bent portion 72 having a soft portion 74 formed of the same material as that of the laminated portion 70, the lip portion 65 is smaller when the roof molding 50 is attached to the roof groove 32. The bent portion 72 is easily bent by force. In this way, the roof molding 50 can be attached to the roof groove 32 with a smaller force.

On the other hand, in the roof molding 50 mounted so as to be elastically locked to the side wall portion 38 of the roof groove 32, the main body portion 68 of the lip portion 65 is an elastic polymer material having higher hardness than the elastic polymer material forming the laminated portion 70. Therefore, the laminated portion 70 is pressed more strongly against the side wall portion 38 of the roof groove 32 than the case where the main body portion 68 of the lip portion 65 is made of an elastic polymer material forming the laminated portion 70. Can do. As a result, the frictional force of the lip portion 65 against the side wall portion 38 of the roof groove 32 is increased, and the direction in which the roof molding 50 comes out of the roof groove 32 (typically from the leg portion 60 of the roof molding 50 to the head portion 55). Even when a force in a direction toward the roof acts, the roof molding 50 is difficult to come out of the roof groove 32.
Furthermore, in the roof molding 50 according to the present embodiment, the static friction coefficient and the dynamic friction coefficient between the laminated portion 70 and the side wall portion 38 of the roof groove 32 are between the main body portion 68 and the side wall portion 38 of the roof groove 32, respectively. Therefore, when a force in the direction of pulling out from the roof groove 32 is applied to the roof molding 50, the surface layer portion of the lip portion 65 is formed by the elastic polymer material forming the main body portion 68. The lip portion 65 does not move unless a greater force is applied compared to the formed case. As a result, the roof molding 50 is more effectively prevented from coming out of the roof groove 32.

  The shape of the roof molding is not limited to that of the above embodiment. For example, a modification example described below is given. FIG. 5 is a cross-sectional view schematically showing the structure of the roof molding 150 according to the second embodiment. FIG. 6 is a cross-sectional view schematically showing a state where the roof molding 150 according to the second embodiment is mounted in the roof groove 32. FIG. 7 is a cross-sectional view schematically showing the structure of the roof molding 250 according to the third embodiment. FIG. 8 is a cross-sectional view schematically showing a state where the roof molding 250 according to the third embodiment is mounted in the roof groove 32.

First, the roof molding 150 according to the second embodiment will be described.
As shown in FIGS. 5 and 6, the roof molding 150 according to the present embodiment has at least the groove width direction of the roof groove 32 (width direction of the vehicle 10) when the roof molding 150 is attached to the roof groove 32. A head portion 155 that covers a part, a leg portion 160 that protrudes from the back surface side of the head portion 155 toward the bottom wall portion 36 of the roof groove 32, and both width directions of the lower end of the leg portion 160 (width direction of the vehicle 10). Lip portions 165 and 165 respectively projecting from both sides of the roof groove 32 toward both side wall portions 38 and 38.
The lip portion 165 is formed of a main body portion 168 made of an elastic polymer material and an elastic polymer material whose hardness is lower than that of the elastic polymer material forming the main body portion 168, as in the roof molding 50 according to the first embodiment described above. The laminated portion 170 is provided. The laminated portion 170 is formed so as to constitute at least a part of the surface layer portion of the lip portion 165 that is in contact with the side wall portion 38 of the roof groove 32.

Bent portions 172 and 172 are formed in the lip portions 165 and 165 according to the present embodiment, respectively. The thickness of the bent portion 172 is formed so as to be thinner than the portion adjacent to the bent portion 172 (that is, formed in a shape narrower than the adjacent portion).
Further, a notch 180 that is continuous over the entire length of the roof molding 150 in the longitudinal direction is formed on the surface of the bent portion 172 facing the bottom wall portion 36 of the roof groove 32. The notch 180 according to the present embodiment is formed so that the cross-sectional shape is substantially semicircular, but may be substantially semicircular or U-shaped.
According to such a configuration, similarly to the first embodiment described above, since the laminated portion 170 is formed on the surface layer portion of the lip portion 165, the lip portion 165 can be deformed with a smaller force. Further, when a force in the direction of the head 155 (the direction of the arrow X in FIG. 6) is applied to the tip portion of the lip portion 165 when the roof molding 150 is attached to the roof groove 32, the bent portion 172 becomes the notch 180. The lip portion 165 easily bends at the portion where is formed. As described above, the roof molding 150 can be attached to the roof groove 32 with a smaller force. The effect after the roof molding 150 is attached to the roof groove 32 is the same as that of the first embodiment described above.

Next, the roof molding 250 according to the third embodiment will be described.
As shown in FIGS. 7 and 8, the roof molding 250 according to the present embodiment has at least the groove width direction of the roof groove 32 (the width direction of the vehicle 10) when the roof molding 250 is attached to the roof groove 32. A head portion 255 that covers a part, a leg portion 260 that protrudes from the back surface side of the head portion 255 toward the bottom wall portion 36 of the roof groove 32, and both sides in the width direction (width direction of the vehicle 10) of the lower end of the leg portion 260. Lip portions 265 and 266 projecting toward the both side wall portions 38 and 38 of the roof groove 32 respectively.
The lip portion 265 is formed of a main body portion 268 made of an elastic polymer material and an elastic polymer material whose hardness is lower than that of the elastic polymer material forming the main body portion 268, as in the roof molding 50 according to the first embodiment described above. The laminated portion 270 is provided. The laminated portion 270 is formed so as to constitute at least a part of the surface layer portion of the lip portion 265 that contacts the side wall portion 38 of the roof groove 32. Further, a bent portion 272 is formed in the lip portion 265. The bent portion 272 according to the present embodiment is configured by a soft portion 274 made of an elastic polymer material that forms the laminated portion 270 as a whole, including the surface layer portion on the side facing the bottom wall portion 36 of the roof groove 32.
In the roof molding 250 according to the present embodiment, the lip portion 266 of the lip portions 265 and 266 is composed only of the main body portion 268, and the surface layer portion has a laminated portion 270 like the lip portion 265. Not. Further, as shown in FIG. 7, the distance d between the tip portions of the lip portions 265, 266 in the natural state is longer than the distance b (see FIG. 8) in the groove width direction of the roof groove 32. , 266 are formed.

According to this configuration, since the laminated portion 270 is formed on the surface layer portion of the lip portion 265, the lip portion 265 can be deformed with a smaller force. Further, when the roof molding 250 is attached to the roof groove 32, if a force in the head 255 direction (the direction of the arrow X in FIG. 8) is applied to the tip portion of the lip portion 265, the soft portion 274 is formed. The lip portion 265 is easily bent at the bent portion 272. As described above, the roof molding 150 can be attached to the roof groove 32 with a smaller force.
On the other hand, in the roof molding 250 mounted in the roof groove 32, most of the lip portion 265 is the main body portion 268 made of an elastic polymer material having a hardness higher than that of the elastic polymer material forming the laminated portion 270. The laminated portion 270 can be more strongly pressed against the side wall portion 38 of the roof groove 32 as compared with the case where the main body portion 268 is made of an elastic polymer material forming the laminated portion. Furthermore, the lip portion 266 is composed of a main body portion 268 and has no bent portion, so that it is difficult to deform. For this reason, the roof molding 250 can be mounted at a certain distance from the side roof panel 28.
