An embodiment of the present invention will be described with reference to FIGS.
FIG. 6 is a front view of the front door 1 of the automobile, and FIG. 5 is a front view of the glass run 10 of the front door attached to the door frame 2 of the door 1. As shown in FIG. 6, a door frame 2 is provided on the upper portion of the door 1, and a door glass 5 is attached so as to be movable up and down. That is, a glass run 10 is attached to the inner periphery of the door frame 2 to guide the raising and lowering of the door glass 5 and to seal between the door glass 5 and the door frame 2.

As shown in FIG. 5, the glass run 10 is attached to the linear portion 11 formed by extrusion as a whole and the corner portion of the door frame 2, and is formed by molding by connecting the linear portion 11 described above. The glass run corner portion 12 is formed.
The linear portion 11 includes a glass run upper side portion 15 attached to the door frame upper side portion 2b of the door frame 2 and a glass run vertical side attached to the door frame vertical side portion 2a which is a vertical side portion on the rear side of the door frame 2. It consists of the part 14 and the part attached to the division sash which makes the front side vertical side part of the door frame 2. As shown in FIG.

  The glass run upper side portion 15 and the glass run vertical side portion 14 are connected by molding at the corner portions on the front side and the rear side so that these extruded portions have shapes corresponding to the door frame 2. Thus, a glass run corner portion 12 is formed. The rear glass run corner 12 is attached to the door frame corner 2h.

  Hereinafter, the present invention is mounted on a door frame corner portion 2h which is a rear corner portion formed by a door frame vertical side portion 2a and a door frame upper side portion 2b which are rear side vertical sides of the front door 1. The glass run upper side part 15, the glass run vertical side part 14, and the glass run corner part 12 of the linear part 11 will be described as an example.

1 is a cross-sectional view of the glass run vertical side portion 14 taken along the line AA in FIG. 5, and FIG. 2 is a cross-sectional view of the glass run upper side portion 15 taken along the line BB in FIG. . FIG. 3 is a perspective view of the glass run corner portion 12. FIG. 4 is a perspective view of the door frame corner portion 2h.
First, the door frame 2 will be described. The glass run vertical side portion 14 of the glass run 10 will be described, and then the glass run upper side portion 15 and the glass run corner portion 12 will be described.

  As shown in FIG. 4, the door frame 2 has a shelf portion 2 f that is recessed in the vehicle interior at the flange portion at the tip of the door outer panel 2 c in the upper side 2 b of the door frame. The flange portion of the door inner panel 2d extends in a planar shape. A door reinforcing panel 2e is provided between the door outer panel 2c and the door inner panel 2d, and the tip of the door reinforcing panel 2e is joined to the tip of the door inner panel 2d. A convex portion 2j is formed slightly above the tip of the door reinforcing panel 2e. Further, the door reinforcing panel 2e is bent at a substantially right angle so as to close the space between the door outer panel 2c and the door inner panel 2d to form a holding surface 2k, and further bent and formed in parallel with the door outer panel 2c. And is joined to the door outer panel 2c at its tip.

In the door frame vertical side part 2a of the door frame 2, the front-end | tip part of the door outer panel 2c is formed in planar shape. For this reason, when the door frame 2 is viewed from the vehicle exterior side, the vehicle exterior surface is flat and looks good.
The front end of the door frame vertical side portion 2a forms a folded portion 2g that is bent in the shape of a hairpin inside the vehicle. For this reason, the rigidity of the front-end | tip part of the door frame vertical side part 2a can be raised.
The shapes of the door inner panel 2d and the door reinforcing panel 2e are the same as those of the door frame upper side 2b.

  In the door frame corner portion 2h, the door outer panel 2c has a linear extension portion of the door frame upper side portion 2b and the door frame vertical side portion 2a, and a concave portion 2m is formed at the joining portion. A rib 23b of a glass run corner portion 12 to be described later is fitted into the recess 2m. The door inner panel 2d and the door reinforcing panel 2e are continuously formed in a curved shape from the door frame upper side 2b to the door frame vertical side 2a.

Next, the glass run 10 will be described.
As shown in FIG. 1, the glass run vertical side portion 14 of the glass run 10 has a main body formed from a vehicle outer side wall 20, a vehicle inner side wall 30, and a bottom wall 40 in a substantially U-shaped cross section. As will be described later, the vehicle interior side wall 30 is larger than the vehicle exterior side wall 20 and is thick, and the substantially U-shaped cross section is formed in an asymmetric shape with a large vehicle interior.
The main body of the glass run 10 has basically the same substantially U-shaped cross-section in both the portion attached to the upper side portion of the door frame 2 and the portion attached to the vertical side portion.

The vehicle outer side wall 20 of the glass run 10 is formed in a substantially plate shape in cross section.
A vehicle outer side seal lip 21 extends from the vicinity of the front end of the vehicle outer side wall 20 toward the inside of the main body having a substantially U-shaped cross section. Further, the vehicle outer side cover lip 23 is formed to be short so as to cover the front end of the door outer panel 2c from the front end of the vehicle outer side wall 20 in the vehicle outward direction.

  For this reason, the front end of the vehicle outer side cover lip 23 does not protrude from the plane of the door outer panel 2c, and when viewed from the vehicle outer side, the glass run 10 does not stand out and looks good. Further, the vehicle outer side wall 20 can be held by sandwiching the flange portion of the door outer panel 2c with the vehicle outer side holding lip 24 and the vehicle outer side cover lip 23 described later.

  A vehicle outer side sub-seal lip 22 extending from the front end of the vehicle outer side wall 20 of the glass run vertical side portion 14 toward the inner side of the main body of the glass run 10 so as to contact the door glass 5 is formed. Yes. For this reason, the vehicle outer side seal lip 21 and the vehicle outer side sub seal lip 22 can perform double sealing with respect to the outer surface of the door glass 5, and can improve sealing performance. Moreover, since the vehicle-side sub-seal lip 22 abuts on the door glass 5 at an obtuse angle, there is no dent between them, and wind noise and the like can be reduced.

Two outer side holding lips 24 are formed on the outer surface of the outer side wall 20. As described above, the front end of the door outer panel 2c is bent into a hairpin shape on the inner side to form a folded portion 2g. The vehicle outer side holding lip 24 is engaged with the folded portion 2g, and the vehicle outer side cover lip 23 and The folded portion 2g is clamped by the vehicle outer side holding lip 24. Thereby, the vehicle exterior side wall 20 can be hold | maintained at the door outer panel 2c.
For this reason, while being able to latch the vehicle outer side wall 20 to the door outer panel 2c reliably, between the vehicle outer side wall 20 and the door outer panel 2c can be sealed.

As described above, the outside seal lip 21 extends obliquely toward the inside of the main body of the glass run 10 on the inside of the outside wall 20.
When the door glass 5 rises and the upper end of the door glass 5 enters the inside of the upper side of the main body of the glass run 10, the vehicle outer seal lip 21 and the later-described seal lip 21 are formed on both sides of the upper end of the door glass 5. The vehicle interior seal lip 31 elastically abuts to seal between the front end of the door glass 5 and the door frame 2.

  Low sliding members can be provided on the surfaces of the vehicle outer seal lip 21 and the vehicle inner seal lip 31. In this case, when the door glass 5 moves up and down and slides on the glass run 10 at the vertical side, the contact area and frictional resistance between the door glass 5 and the glass run 10 are reduced, and the sliding resistance is reduced. Therefore, it is possible to prevent the generation of abnormal noise and to ensure smooth elevation. Further, even when the door glass 5 moves up and down due to the bending of the door glass 5 and the negative pressure during traveling, or even when the door glass 5 is bent and strongly pressed against the outer seal lip 21, the door glass 5 is slid. Smooth elevation can be ensured without increasing the dynamic resistance.

  In the case where a low sliding member is provided on the surface of the vehicle outer side seal lip 21 and the vehicle inner side seal lip 31 on which the door glass 5 abuts, the low sliding member slides with a high ratio of the olefin portion of the thermoplastic elastomer. It is formed when a material having low resistance is formed by co-extrusion on the surface of the vehicle interior seal lip 31 with a thickness of about 0.1 mm, or by applying a low sliding member such as urethane resin. For this reason, when the door glass 5 slides in the glass run 10, the sliding resistance can be reduced, and the generation of abnormal noise and the displacement of the glass run 10 can be prevented.

  Further, protrusions may be formed on the inner surface of the vehicle outer side wall 20 and the rear surface of the vehicle outer seal lip 21, or the low sliding member may be extruded, applied, or pasted. In this case, even if the vehicle outer side seal lip 21 is in close contact with the vehicle outer side wall 20 by being pushed by the door glass 5, sticking between the vehicle outer side seal lip 21 and the vehicle outer side wall 20 can be prevented.

The bottom wall 40 is formed in a substantially plate shape, and a groove portion is formed in a continuous portion between the vehicle inner side wall 30 and the vehicle outer side wall 20 so as to be easily bent.
A low-sliding member is extruded on the inner surface of the main body of the glass run 10 of the bottom wall 40 in the same manner as the vehicle outer seal lip 21 and the vehicle inner seal lip 31, or a low-sliding material such as urethane resin is used. The member is applied. For this reason, sliding resistance with the door glass 5 can be reduced.

The vehicle interior side wall 30 is formed thicker and larger than the vehicle exterior side wall 20. For this reason, the glass run 10 can be held on the side surface of the door frame 2.
A vehicle inner side cover lip 33 extends from the front end of the vehicle inner side wall 30 in parallel with the vehicle inner side wall 30 in the outer surface side of the vehicle inner side wall 30, that is, in the vehicle interior direction. The vehicle interior cover lip 32 and the vehicle interior side wall 30 sandwich a flange portion where the distal end of the door inner panel 2d and the distal end of the door reinforcing panel 2e are joined.

  Similar to the vehicle outer side wall 20, a vehicle inner seal lip 31 extends obliquely from the tip of the vehicle inner side wall 30 toward the inside of the main body of the glass run 10. Since the vehicle interior seal lip 31 is longer and thicker than the vehicle exterior seal lip 21, the door glass 5 can be positioned on the vehicle exterior side when the door glass 5 enters the glass run 10. The step difference between the door frame 2 and the door glass 5 can be reduced. For this reason, air resistance and wind noise are reduced, which is preferable in terms of design.

  A vehicle interior holding lip 34 is formed on the outer surface of the vehicle interior side wall 30 in the vicinity of the continuous portion with the bottom wall 40. The door reinforcing panel 2e of the door frame 2 is formed with a convex portion 2j bent, and the vehicle interior holding lip 34 is locked to the convex portion 2j. For this reason, the glass run 10 can be held on the door frame 2.

  Next, the glass run upper side 15 will be described with reference to FIG. In the glass run upper side portion 15, the shape of the vehicle outer side cover lip 23 is different from the glass run vertical side portion 14, and the vehicle outer side sub seal lip 22 does not exist, but the other portions are the same as the glass run vertical side portion 14, Only different parts will be described, and description of the same parts will be omitted.

The vehicle outer side cover lip 23 extends in parallel to the outer surface of the vehicle outer side wall 20 from the front end of the vehicle outer side wall 20 and is longer than the vehicle outer side cover lip 23 of the glass run vertical side portion 14.
A flange formed on the door outer panel 2c is formed by inserting a flange portion of the door outer panel 2c of the door frame upper side 2b between the vehicle outer side wall 20 and the vehicle outer cover lip 23 and covering the tip of the vehicle outer cover lip 23. The tip of the vehicle outer side cover lip 23 is in contact with the portion 2f. As a result, the flange portion of the door outer panel 2c can be held between the vehicle outer cover lip 23 and the vehicle outer side wall 20, and the vehicle outer cover lip 23 can be flush with the door outer panel 2c at the tip. . In the glass run upper side portion 15, a sun visor or the like is often attached to the door frame upper side portion 2 b, and the vehicle outer side cover lip 23 is less noticeable when viewed from the vehicle outer side.

The glass run corner portion 12 will be described with reference to FIG.
The glass run corner portion 12 connects the glass run upper side portion 15 and the glass run vertical side portion 14 by molding. About the vehicle inner side wall 30, the vehicle inner side seal lip 31, and the vehicle inner side cover lip 33, since the shape of the glass run upper side part 15 and the glass run vertical side part 14 is the same, it can connect easily.

Similarly, the vehicle outer side wall 20 and the vehicle outer seal lip 21 can be easily connected since the glass run upper side portion 15 and the glass run vertical side portion 14 have the same shape.
The vehicle outer side sub-seal lip 22 comes into contact with the tip of the vehicle outer side wall 20 at the glass run corner portion 12 and ends.

  The vehicle outer cover lip 23 of the glass run upper side portion 15 is formed longer than the vehicle outer cover lip 23 of the glass run vertical side portion 14. Therefore, in the vehicle outer cover lip 23 of the glass run corner portion 12, the vehicle outer cover lip 23 extends in the width direction from the vehicle outer cover lip 23 of the glass run upper side portion 15 to the vehicle outer cover lip 23 of the glass run vertical side portion 14. Change the length gradually and connect continuously. Then, the outside cover lip 23 of the glass run corner 12 changes smoothly without any steps, and is mounted along the door outer panel 2c of the door frame corner 2h, so that the sealing performance and appearance are good.

  The vehicle outer cover lip 23 of the glass run corner portion 12 has a length in the width direction of the vehicle outer cover lip 23 from the vehicle outer cover lip 23 of the glass run upper side portion 15 to the vehicle outer cover lip 23 of the glass run vertical side portion 14. The outer outer cover lip 23 is gradually shortened and continuously connected, and the front end of the vehicle outer cover lip 23 gradually approaches the vehicle outer side wall 20 and comes into contact with the front end of the flange portion of the door outer panel 2c. 2c and the front-end | tip of the vehicle outer side cover lip 23 can be formed so that there may be substantially no level | step difference. In this case, the glass run vertical side portion 14 is formed without the front end of the vehicle outer side cover lip 23 contacting the front end of the door outer panel 2c and protruding from the door outer panel 2c. For this reason, it looks good from the outside of the vehicle, and at the glass run corner portion 12, the tip of the glass run upper side portion 15 and the glass run vertical side portion 14 can be continuously connected.

  As shown in FIG. 3, at the bent portion of the glass run corner portion 12, a rib 23 b is formed between the vehicle outer side wall 20 on the glass run upper side 15 side and the vehicle outer cover lip 23. When the glass run corner portion 12 is mounted on the door frame corner portion 2h, it is possible to prevent the glass run corner portion 12 from being displaced due to the ribs 23b fitted into the recess 2m of the door outer panel 2c.

In the molding of the linear portion 11, a synthetic rubber or a thermoplastic elastomer is used as a molding material. For example, an EPDM rubber is used for a synthetic rubber, and a polyolefin-based elastomer is used for a thermoplastic elastomer.
In the case of synthetic rubber, it is conveyed to a vulcanizing tank after extrusion and heated by hot air or high frequency to vulcanize. In the case of a thermoplastic elastomer, it is cooled and solidified. Thereafter, it is cut to a predetermined length to produce an extruded part.

  Next, the molded portion of the glass run corner portion 12 is formed by cutting the extruded member manufactured as described above into a predetermined dimension at a substantially right angle to the longitudinal direction, and the end portion of the cut extruded portion is formed into a mold. The molded part is sandwiched between molding dies, and a solid material for forming the molded part is injected into the cavity of the mold. The cross-sectional shape of the molded part is substantially the same as the cross-sectional shape of the extruded part. It is preferable to use the same type of molding material as that used for the extruded part. In the case of a thermoplastic elastomer, since the injected material is melted when injected into the mold, the extruded part and the molded part are integrally fused by the heat and pressure.

When the linear portion 11 is formed of EPDM rubber, the glass run corner portion 12 is preferably formed of EPDM rubber or an olefin-based thermoplastic elastomer. When the linear part 11 is formed of an olefinic thermoplastic elastomer, the glass run corner part 12 is formed of an olefinic thermoplastic elastomer. In this case, it is the same kind of material, and the adhesion between the linear portion 11 of the glass run 10 and the glass run corner portion 12 is good. In addition, both are olefin-based materials, have good weather resistance, can be pulverized at the same time, and can be easily recycled. In the case of an olefin-based thermoplastic elastomer, vulcanization is not required, and therefore production is easy.
In the case of synthetic rubber, the mold is heated and vulcanized after being poured into the mold. At this time, since the extrusion molding part and the molding part use the same material or the same kind of material, vulcanization adhesion can be performed, and they can be fixed integrally.
