Description

  The present invention relates to a glass run for an automobile in which a glass run having a straight part and a corner part for guiding the raising and lowering of a door glass is attached to the inner periphery of a door frame of an automobile door.

As shown in FIG. 9, a glass run 110 for guiding the raising and lowering of the door glass 5 is attached to the inner periphery of the door frame 2 of the door 1 of the automobile.
Conventionally, as shown in FIG. 9, the glass run 110 is attached in the channel 103 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. .

  Further, as shown in FIG. 8, the glass run 110 includes an upper side portion of the door frame 2 formed by the straight portion 111 formed by extrusion molding, a front side vertical side portion and a rear side formed by the straight portion 111 that is also extruded. The side vertical sides are connected by a corner 112 formed by molding to match the shape of the corner 2b of the door frame 2.

  In addition, the seal between the door 1 and the vehicle body is an opening attached to a door weather strip (not shown) attached to the outer periphery of the door panel and the door frame 2 and / or a flange formed in the opening of the vehicle body. It is made by a trim weather strip (not shown).

  As shown in FIG. 10, the straight portion 111 of the main body of the glass run 110 has a substantially U-shaped cross section including a vehicle outer side wall 120, a vehicle inner side wall 130, and a bottom wall 140. A vehicle outer side seal lip 121 is provided so as to extend from the vicinity of the front end of the vehicle outer side wall 120 toward the inside of the main body having a substantially U-shaped cross section. Further, a vehicle inner side seal lip 131 is also provided on the vehicle inner side wall 130 so as to extend from the vicinity of the front end thereof toward the inside having a substantially U-shaped cross section.

The vehicle outer side wall 120, the vehicle inner side wall 130 and the bottom wall 140 of the main body of the glass run 110 are inserted into the channel 103 provided in the door frame 2, and at least a part of the outer surface of each wall is pressed against the inner surface of the channel 103. The glass run 110 is held.
The door glass 5 slides on the inside of the main body of the glass run 110 with a substantially U-shaped cross section, and both side surfaces of the end portion of the door glass 5 are sealed by the vehicle exterior seal lip 121 and the vehicle interior seal lip 131. (For example, refer to Patent Document 1).

  However, in the press door of a vehicle, in order to fit and fix the channel 103 in the door frame 2, the flanges 2e and 2f at the front ends of the door outer panel 2c and the door inner panel 2d of the door frame 2 are welded. In order to secure the welding allowance, the flange portions 2e and 2f are wide and unpleasant in appearance, and in order to cover the flange portions 2e and 2f, a wide vehicle outer cover lip 123 and a vehicle are provided on the glass run 110, respectively. It was necessary to provide an inner cover lip 133.

  Therefore, it takes time and effort to weld the channel 103 to the flange portions 2e and 2f, and the widths of the channel 103, the flange portions 2e and 2f, the vehicle outer side cover lip 123 and the vehicle inner side cover lip 133 are increased, and the respective weights are increased. This is contrary to the demand for lighter vehicles.

  Therefore, the channel 103 is abolished and the glass run 110 is directly attached to the flange portions 2e and 2f. However, in this case, as the door glass 5 moves up and down, the front end of the door glass 5 pushes up the bottom wall 140 of the glass run 110, and the glass run 110 is deformed or the glass run 110 is shifted upward and looks good. Sealing performance may deteriorate or abnormal noise may occur.

For this reason, as shown in FIG. 11, in the upper side of the glass run 210, legs 241 and 241 are formed as stopper members on the outer surface of the bottom wall 240 so as to come into contact with the door inner panel 2 d ( For example, see Patent Document 2.)
However, in this case, since the legs 241 and 241 and the vehicle outer side wall 220, the vehicle inner side wall 230, the vehicle outer side seal lip 221 and the vehicle inner side seal lip 231 are molded with the same material, the material hardness is increased. It was difficult to prevent the glass run 210 from being deformed or displaced due to the raising and lowering of the door glass 5.

  Further, as shown in FIG. 12, a stopper member 360 made of metal having a U-shaped cross section is attached to the inside of the door frame 2, and the vehicle outer side wall 320, the vehicle inner side wall 330, the bottom wall of the glass run 310 are attached to the stopper member 360. There is one that holds the glass run 310 by abutting 340 (see, for example, Patent Document 3).

  In this case, since the stopper member 360 is made of metal, it is possible to prevent the glass run 210 from being deformed or displaced by raising and lowering the door glass 5. However, the stopper member 360 is held on the vehicle interior side wall 330. The engaging protrusion 337 is fitted into the engaging hole 365 of the stopper member 360. For this reason, there is a problem that the stopper member 360 is dropped from the glass run 310 when the glass run 310 is transported or assembled to the vehicle.

An embodiment of the present invention will be described with reference to FIGS.
FIG. 9 is a front view of the side door 1 of the automobile, and FIG. 8 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. 9, 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. 8, the glass run 10 is attached to the straight portion 11 formed by extrusion molding as a whole and the corner portion 2b of the door frame 2, and is formed by molding by connecting the straight portion 11 described above. Corner portion 12.
The straight portion 11 includes a portion attached to the upper side portion of the door frame 2, a portion attached to the rear side vertical side portion of the door frame 2, and a portion attached to the front side vertical side portion of the door frame 2.

  The corners 12 are formed by forming the extruded parts by molding at the front and rear corners so as to have a shape corresponding to the door frame 2 and connecting the straight parts 11. Yes. The corner portion 12 of the glass run 10 is attached to the corner portion 2b of the door frame 2.

Hereinafter, the upper side and the corner 12 of the straight line portion 11 of the glass run 10 attached to the rear corner 2b formed by the rear vertical side and the upper side of the side door 1 will be described as an example. .
FIG. 1 is a cross-sectional view of the corner portion 12 on the rear side of the glass run 10 along the line AA in FIG. 2, and FIG. 7 shows a straight portion 11 in the vertical side portion of the glass run 10 in FIG. 2 is a cross-sectional view taken along line -B, FIG. 2 is an enlarged front view of a corner portion 12 to which a stopper member 60 described later is attached, and FIG. 3 is an enlarged front view of the corner portion 12 before the stopper member 60 is attached. It is.
First, the upper side part of the linear part 11 is demonstrated, and the corner part 12 is demonstrated after that.

  As shown in FIG. 7, the cross-sectional shape of the straight portion 11 of the glass run 10 attached to the upper side of the door frame 2 is substantially perpendicular to the bottom wall 40 from the bottom wall 40 and the vehicle outer side edge of the bottom wall 40. Alternatively, from the vehicle outer side wall 20 extending downward (downward in FIG. 2) at a slightly obtuse angle, and the vehicle inner side wall 30 extending downward from the vehicle inner side edge portion of the bottom wall 04 substantially perpendicularly or slightly at an obtuse angle downward. The cross section is formed in a substantially U shape. 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.
In the above, the vehicle exterior and vehicle interior refer to the vehicle interior and vehicle interior of the vehicle with the door 1 closed, and the up and down directions in the upper and lower directions refer to the vertical direction of the vehicle. It is shown.

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 extends from the front end of the vehicle outer side wall 20 toward the outside of the vehicle outer side wall 20 in the substantially U-shaped cross section, that is, parallel to the vehicle outer side wall 20 in the vehicle outer direction. The vehicle outer side cover lip 23 covers the flange portion 2e at the tip of the door outer panel 2c.

  The vehicle inner side surface of the flange portion 2 e of the door outer panel 2 c of the door frame 2 abuts on the outer surface side of the vehicle outer side wall 20. The vehicle outer side holding lip 24 is formed on the bottom wall 40 side of the outer side surface of the vehicle outer side wall 20, and the vehicle outer side holding lip 24 abuts on the flange portion 2e. For this reason, while being able to latch the vehicle outer side wall 20 to the flange part 2e reliably, between the vehicle outer side wall 20 and the flange part 2e can be sealed.

As described above, the vehicle outer side seal lip 21 extends obliquely inside the vehicle outer side wall 20 toward the inner side of the main body of the glass run 10 having a substantially U-shaped cross section.
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 exterior seal lip 21 and the vehicle interior described later are formed on both surfaces of the upper end of the door glass 5. The seal lip 31 is elastically contacted to seal between the front end of the door glass 5 and the door frame 2. Low sliding members and ridges can be formed on the surfaces of the vehicle outer seal lip 21 and the vehicle inner seal lip 31 in order to reduce sliding resistance.

The bottom wall 40 is formed in a substantially plate shape, and a groove portion 41 is formed so that it can be easily bent at a continuous portion between the vehicle inner side wall 30 and the vehicle outer side wall 20.
A bottom wall lip 42 is formed on the outer surface of the bottom wall 40 (upper surface in FIG. 7). For this reason, when rainwater or the like enters from the door outer panel 2c through the vehicle outer side cover lip 23 and the vehicle outer side wall 20, it is possible to prevent the bottom wall lip 42 from entering the vehicle.

  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. Further, a bottom wall inner lip 46 can be formed on the inner surface of the bottom wall 40. In this case, when the door glass 5 is raised, the bottom wall inner lip 46 comes into contact with the tip of the door glass 5 to improve the sealing performance and reduce the impact of the door glass 5 on the bottom wall 40. it can.

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 outside the vehicle.
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 33 and the vehicle interior side wall 30 sandwich the flange portion 2f at the tip of the door inner panel 2d.

  Similar to the vehicle outer side wall 20, a vehicle inner seal lip 31 extends obliquely from the front end of the vehicle inner side wall 30 in an internal direction having a substantially U-shaped cross section 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.

On the inner surface of the vehicle inner side wall 30, a vehicle inner sub lip 32 is formed that contacts the inner surface of the vehicle inner seal lip 31 and holds the vehicle inner seal lip 31. For this reason, the vehicle inner side seal lip 31 is prevented from coming into close contact with the vehicle inner side wall 30, thereby preventing the generation of abnormal noise and improving the sealing performance between the door glass 5 and the vehicle inner side seal lip 31.
The flange portion 2 f of the door frame 2 is bent at the tip and is locked to the vehicle interior engagement convex portion 37 formed on the front end side of the outer surface of the vehicle interior side wall 30. For this reason, the glass run 10 can be held on the door frame 2.

Next, the rear corner portion 12 of the glass run 10 will be described with reference to FIG.
FIG. 1 is a cross-sectional view on the upper side of the corner portion 12 of the glass run 10, and is a cross-sectional view along the line AA in FIG. FIG. 2 shows a state in which a stopper member 60 described later is attached to the corner portion 12 of the glass run 10, and FIG. 3 shows a state before the stopper member 60 is attached.

  As shown in FIG. 2, the corner 12 of the glass run 10 is formed by connecting the extrusion linear part 11 forming the upper side part and the extrusion linear part 11 forming the rear side vertical part by molding. It is. The cross-sectional shape is substantially the same as the cross-sectional shape of the linear portion 11 of the extrusion molding described above. That is, the main body is formed in a substantially U-shaped cross section from the vehicle outer side wall 20, the vehicle inner side wall 30, and the bottom wall 40, but the difference in cross-sectional shape between the upper side portion and the rear side vertical side portion. The connection is made by continuously changing the corner portion 12.

  A bottom wall lip 42 extends upward (upward in FIG. 1) from the outer surface of the bottom wall 40. As shown in FIGS. 2 and 3, the bottom wall lip 42 starts from a portion connected to the upper side of the glass run 10 and reaches a curved portion from the upper side of the corner portion 12 to the vertical side of the corner portion 12. It is extended so far. The bottom wall lip 42 of the corner portion 12 is formed higher than the bottom wall lip 42 on the upper side of the glass run 10.

As shown in FIG. 3, bottom wall mounting ribs 43 are formed in the width direction of the bottom wall lip 42 at portions where the stopper members 60 on both sides of the bottom wall lip 42 are attached. In the present embodiment, three bottom wall mounting ribs 43 are formed, but the number can be appropriately selected. The stopper member 60 and attachment will be described later.
A bottom wall mounting rib locking groove 45 that locks the stopper member 60 can be formed in a direction perpendicular to the bottom wall mounting rib 43 (longitudinal direction of the bottom wall lip 42).

  A bottom wall extension lip 44 extends in the extending direction of the bottom wall lip 42 from the tip of the bottom wall lip 42 where the stopper member 60 is attached, that is, where the bottom wall mounting rib 43 is formed. For this reason, when attaching the stopper member 60, the stopper member 60 can be easily attached to the glass run 10 by picking and pulling the bottom wall extension lip 44.
