Description

The present invention relates to a grass run mounted on a frame of an automobile and a mounting structure for the grass run.

Conventionally, in a glass run mounted on a door frame of an automobile, the glass run is unintentionally moved from the original mounting position as the door glass is moved up and down, the appearance is deteriorated, and the glass frame is dropped from the door frame. There was a problem. In order to solve this problem, the development of grass run having various structures is in progress.

For example, Patent Document 1 discloses a glass run (glass run) including a first mold molding part and a second mold molding part. In this glass run, a first locking protrusion is provided in the first mold forming portion to restrict downward movement of the glass run due to movement of the window glass (door glass) from the closed state to the open state. At the same time, the second mold forming portion is provided with a second locking protrusion that restricts the upward movement of the glass run accompanying the movement of the window glass from the open state to the closed state. Further, movement restricting protrusions are provided at the upper end and the lower end of a molding forming a part of the window frame (door frame), and the two movement restricting protrusions are connected to the first locking protrusion and the first locking protrusion. The glass run is held by the window frame by sandwiching the glass run with the two locking projections.

In addition, for example, in Patent Document 2, a positioning projection that is inserted into a notch formed in an inner side portion of a molding having a substantially U-shaped cross section to prevent longitudinal displacement of the inner side portion of the grass run is provided on the outer surface of the grass run. A grass run projecting near the corner is disclosed.

Japanese Unexamined Patent Publication No. 2001-206069 (Published July 31, 2001) Japanese Utility Model Publication No. 7-11417 (Published February 21, 1995)

However, the glass run disclosed in Patent Document 1 assumes a door having a structure in which a sash is present also in a corner portion of a window frame, such as a sash door, as an attachment target. It is not designed to be mounted on a door with a structure where sash does not exist at the corner. Therefore, when the glass run is attached to, for example, a sliding door, the glass run cannot be held at the corner portion of the window frame, and the glass run does not move due to the difference in linear expansion coefficient between the window frame and the glass run. There was a problem of protruding from the frame and impairing the appearance.

Further, the positioning protrusion of the grass run disclosed in Patent Document 2 is provided at a roof-side portion of the grass run, and a molding having a notch is also attached to the roof. Therefore, the positioning projections and the notches mainly regulate the unintentional movement of the roof side portion of the grass run, and regulate the unintentional movement of the pillar side portion that is more affected by the up and down movement of the door glass. It is not structured. Therefore, in the above-mentioned grass run, there is a problem that the appearance is deteriorated due to the unintentional movement of the portion on the pillar side from the attachment position.

The present invention has been made in view of the above problems, and an object thereof is a glass run to be attached to a door having a structure in which a sash does not exist in a corner portion of a door frame, particularly a protrusion from a mounting position in the corner portion. It is to suppress unintended movement.

In order to solve the above problems, the glass run according to one aspect of the present invention has a vehicle door frame in which a bent portion that is bent toward the door glass center side of the door panel is formed at the inner edge of the corner portion of the door panel. A glass run for guiding the up and down movement of the door glass, the bottom wall facing the end surface of the door glass, and the side edge on the vehicle inner side of the bottom wall, extending toward the center side of the door glass. A vehicle interior side wall, and a vehicle exterior side wall extending from the vehicle exterior side edge of the bottom wall toward the center side of the door glass, the vehicle interior side wall and the vehicle exterior side wall. In any one of the above, at least a pillar-side portion corresponding to the arrangement position of the pillar is formed with a convex portion that is caught by the bent portion to restrict the movement of the grass run with respect to the door panel.

According to the above configuration, in the glass run according to the present invention, the convex portion is formed on at least the pillar side portion of either the vehicle inner side wall or the vehicle outer side wall, and the convex portion is formed on the inner edge of the corner portion of the door panel. The structure is such that it bends and gets caught. Here, the bent portion is generally formed in a door having a structure in which a sash does not exist at a corner portion of a door frame, such as a slide door.

Therefore, the glass run according to the present invention is attached to the door having such a structure, and the extruded portion of the glass run shrinks from the door frame due to the difference in the linear expansion coefficient from the door frame, for example, without being held by the sash at the corner. Even in such a case, the convex portion is caught on the bent portion, so that the position variation of the grass run due to the contraction is restricted. Therefore, the protrusion from the corner portion of the grass run according to the present invention can be effectively suppressed.

Further, regarding unintentional movement from the mounting position, the pillar side portion of the side wall is more strongly affected by the up and down movement of the door glass than the roof side portion. Therefore, the unintended movement of the glass run accompanying the up and down movement of the door glass is effectively suppressed by the catching of the bent portion of the convex portion.

As described above, when the glass run according to the present invention is attached to a door having a structure in which the sash does not exist in the corner portion of the door frame, particularly in the corner portion of the door frame, the protrusion from the attachment position and the unintended movement are effectively suppressed. can do.

In order to solve the above-mentioned subject, in the grass run which concerns on one mode of the present invention, it is preferred that the above-mentioned convex part is formed in the above-mentioned pillar side part in the above-mentioned outside side wall.

Generally, the bent portion is formed on a door outer panel (door panel on the vehicle exterior side) in a door having a structure in which a sash does not exist in a corner portion of a door frame. In that respect, according to the above configuration, since the convex portion is formed at the pillar side portion on the vehicle outer side wall, for example, a structure in which the convex portion is hooked on the door inner panel (door panel on the vehicle inner side) is separately provided. There is no need, and the existing door frame structure can be used as it is. Therefore, with a simple structure, it is possible to effectively prevent the grass run according to the present invention from protruding from the mounting position in the corner portion or moving unintentionally.

Further, in order to solve the above-mentioned problems, in the glass run according to one aspect of the present invention, a vehicle exterior design protrusion projecting toward the vehicle exterior is provided at an end portion of the vehicle exterior side wall on the center side of the door glass. However, it is preferable that the bent portion is formed in a concave portion formed by the convex portion, the vehicle exterior side wall, and the vehicle exterior design protrusion.

According to the above configuration, not only the convex portion is hooked on the bent portion, but also the bent portion is hooked on the side wall of the vehicle exterior design protrusion forming the concave portion, so that it does not protrude from the mounting position of the grass run according to the present invention The movement can be suppressed more reliably.

Further, since the vehicle exterior design protrusion is visible from the vehicle exterior, it is possible to improve the design and appearance of the vehicle door to which the glass run according to the present invention is attached.

Further, in order to solve the above problems, in the glass run according to one aspect of the present invention, the height of the convex portion from the surface of the vehicle exterior side wall facing the door panel is equal to the height of the bent portion of the door panel. It is preferable that the height is not less than 1/2 of the height from the surface of the vehicle facing the outer side wall and is not more than the height from the root of the outer design protrusion.

According to the above configuration, in the state where the glass run according to the present invention is attached to the door frame, the convex portion is reliably caught by the bent portion. Further, the position of the tip of the vehicle exterior design protrusion and the position of the vehicle outer surface of the door outer panel substantially coincide with each other. Therefore, it is possible to more reliably prevent the grass run according to the present invention from protruding from the mounting position and unintended movement, and further improve the design and appearance of the door of the automobile to which the grass run is mounted.

In addition, in order to solve the above problems, in the glass run according to one aspect of the present invention, the convex portion is formed at the pillar side portion of either one of the vehicle inner side wall and the vehicle outer side wall. Preferably, it is formed at the roof side portion corresponding to the position where the roof side is arranged.

According to the above configuration, since the convex portion is formed not only on the pillar side portion but also on the roof side portion, it is possible to hook the convex portion on the bent portion even in the roof side portion in the corner portion of the door panel. it can. Therefore, it is possible to more reliably prevent the grass run according to the present invention from protruding from the mounting position and unintentionally moving.

In order to solve the above-mentioned subject, in the glass run which concerns on one mode of the present invention, the above-mentioned convex part is the 1st linear line which extends in the longitudinal direction of either one of the above-mentioned car side wall and the car outside side wall. And a second filament, and a plurality of third filaments extending in a direction in which the first filament and the second filament are opposed to each other and connecting the first filament and the second filament. It is preferable that a plurality of groove portions surrounded by the first linear line, the second linear line and the third linear line are formed.

According to the above configuration, for example, when molding the molding portion of the grass run (the portion attached to the corner portion of the door frame) according to the present invention, as compared with the case where a plurality of groove portions are not formed in the convex portion In addition, the shape crack of the convex portion due to the existence of the thick portion over a wide range is less likely to occur. Therefore, it is possible to reduce catching defects in the bent portions due to the shape cracks of the convex portions, and more reliably prevent the grass run according to the present invention from protruding and unintended movement from the mounting position.

Further, in order to solve the above problems, a glass run mounting structure according to an aspect of the present invention is a glass run mounting structure that is mounted on a door frame of an automobile and guides a rise and fall of a door glass. Is formed on the inner edge of the corner portion of the door panel constituting the, and is provided with a bent portion bent toward the door glass center side of the door panel, the glass run, the bottom wall facing the end surface of the door glass, and the bottom. From the side edge on the vehicle interior side of the wall, the vehicle interior side wall extending toward the center side of the door glass, and from the side edge on the vehicle exterior side of the bottom wall, extending toward the center side of the door glass. A vehicle exterior side wall that is present, and at least one of the vehicle interior side wall and the vehicle exterior side wall is provided with a convex portion at a pillar-side portion corresponding to the position where the pillar is arranged. Is caught in the bent portion, the movement of the grass run with respect to the door panel is restricted.

According to the above configuration, it is possible to realize a grass run mounting structure capable of effectively suppressing protrusion and unintended movement of the grass run from the mounting position.

According to the present invention, by hooking the convex portion formed on the side wall of the grass run to the bent portion of the corner portion of the door panel, the grass run is projected from the mounting position in the corner portion of the door frame, or is unintentionally moved. Can be suppressed.

In FIG. 1, the left side in the drawing corresponds to the front side (front side), and the right side corresponds to the rear side (rear side).

As shown in FIG. 1, a door frame 101 is integrally formed with a slide door 100 that is openably and closably provided in an opening (not shown) for a rear door of an automobile. In addition, the door frame 101 is guided to move up and down the door glass 102, and when the door glass 102 is lifted to close the window W, a gap between the peripheral edge of the door glass 102 and the door frame 101 is sealed. Glass run 1 is attached. In the glass run 1, the center pillar side extrusion molding section 1a and the roof side extrusion molding section 1b are joined by the front side molding section 1d, and the roof side extrusion molding section 1b and the rear pillar side extrusion molding section 1c are joined by the rear side molding section 1e. Are formed by joining.

With such a configuration, when the door glass 102 is raised and the window W is closed, the three sides of the front end, the upper end, and the rear end of the door glass 102 are held by the three sides of the glass run 1. Further, here, the center of the door glass (the center of the door glass) indicates a substantially middle portion of the door glass 102 indicated by a broken line in FIG.

As shown in FIG. 1, the grass run 1 is attached along the upper portion (roof side portion and center pillar/rear pillar portion) of the door frame 101. That is, the center pillar-side extruded portion 1a is arranged along the center pillar portion of the door frame 101, the roof-side extruded portion 1b is arranged along the roof side portion of the door frame 101, and the rear pillar side is formed along the rear pillar portion of the door frame 101. The extruded parts 1c are attached respectively. Further, an L-shaped front die molding portion 1d is attached along the front corner portion of the door frame 101, and an L-shaped rear die molding portion 1e is attached along the rear corner portion of the door frame 101.

More specifically, as shown in FIGS. 2A and 2B, a center pillar sash 103 having a substantially U-shaped cross section is fixed to the center pillar portion of the door frame 101. The center pillar-side extruded molding portion 1a is fitted (see FIG. 4B). Further, a roof sash 104 having a substantially U-shaped cross section is fixed to a roof side portion of the door frame 101, and the roof side extrusion molding portion 1b is fitted into the roof sash 104. Although not shown, a rear pillar sash is fixed to the rear pillar portion of the door frame 101, and the rear pillar side extrusion molding portion 1c is fitted therein.

On the other hand, due to the structure of the slide door 100, there is no sash for holding the front mold forming portion 1d of the glass run 1 at the front corner of the door frame 101. Although not shown, the rear corner portion of the door frame 101 also has no sash for holding the rear mold forming portion 1e of the glass run 1. Regarding the front corner of the door frame 101, the convex portion 50 formed on the vehicle exterior side wall 12 of the glass run 1 has a structure in which the bent portion 60 formed on the door outer panel (door panel) 101b forming the door frame 101 is hooked. Has become. The rear corners of the door frame 101 have the same structure (details of the protrusion 50 and the bent portion 60 will be described later). With this structure, the front die molding portion 1d and the rear die molding portion 1e are held at the front and rear corner portions of the door frame 101, respectively.

As a molding material for the glass run 1, for example, synthetic rubber, thermoplastic elastomer (TPE) or the like is used. For synthetic rubber, EPDM (ethylene-propylene-diene copolymer rubber), and for thermoplastic elastomer, olefin-based thermoplastic elastomer (TPO). For example, a sponge material (foam material) and a solit material (non-foam material) may be used according to the cross-sectional shape.

The attachment of the glass run 1 described above is merely an example, and the vehicle door to which the glass run according to the present invention is attached is not limited to the slide door 100. That is, any type of door can be attached to the grass run according to the present invention as long as the door has a structure in which there is no sash in the corner portion of the door frame.

<Structure of grass run>
Next, the structure of the grass run according to the present invention will be described with reference to FIGS. 3 and 4. FIG. 3 is a diagram showing a schematic configuration in the vicinity of the front mold forming portion 1d in the glass run 1. FIG. 4A is a sectional view taken along the line AA of the portion of the glass run 1 shown in FIG. FIG. 4B is a sectional view taken along the line BB of the portion of the glass run 1 shown in FIG. FIG. 4C is an enlarged view of the vicinity of the convex portion, the bent portion, and the exterior design protrusion of the grass run shown in FIG. 4A.

Here, FIG. 4 shows a cross section of the door frame 101 and the grass run 1, and the upper side and the lower side of the drawing correspond to the inside and outside of the vehicle, respectively. Further, the left side in the drawing corresponds to the front side (front side), and the right side corresponds to the rear side (rear side).

As shown in FIG. 3, an L-shaped convex portion 50 that substantially conforms to the outer shape of the front die molding portion 1d is formed on the vehicle exterior side wall 12 of the front die molding portion 1d of the grass run 1. The convex portion 50 includes a pillar-side convex portion 50a formed in a region (pillar-side portion) on the center pillar side of the vehicle exterior side wall 12 of the front mold forming portion 1d and a roof side region of the vehicle exterior side wall 12 ( The roof side projection 50b formed on the roof side portion) is connected to the roof side projection 50b.

The pillar-side convex portion 50a includes a pillar-side first linear line (first linear line) 50a-1, a pillar-side second linear line (second linear line) 50a-2, and a plurality of pillar-side third linear lines (first line). 3 lines 50a-3. Both the pillar-side first filament 50a-1 and the pillar-side second filament 50a-2 extend substantially in the vehicle body vertical direction in the center pillar-side region of the vehicle exterior side wall 12, and the pillar-side first filament 50a- 1 is arrange|positioned rather than the pillar side 2nd filament 50a-2 at the front side. In addition, the plurality of pillar-side third filaments 50a-3 respectively connect the pillar-side first filaments 50a-1 and the pillar-side second filaments 50a-2 obliquely so that the front side is higher.

Further, the pillar-side protrusion 50a has a shape of an opening surrounded by each of the pillar-side first filament 50a-1, the pillar-side second filament 50a-2, and the pillar-side third filament 50a-3. A plurality of substantially parallelogrammic grooves 50a-4 are formed.

The roof-side convex portion 50b includes a roof-side first linear line (first linear line) 50b-1, a roof-side second linear line (second linear line) 50b-2, and a plurality of roof-side third linear lines (first linear line). 3 lines 50b-3. Both the roof-side first filament 50b-1 and the pillar-side second filament 50b-2 extend in the longitudinal direction of the roof-side region of the vehicle exterior side wall 12, and the roof-side first filament 50b-1 , And is arranged on the vehicle body upper side than the roof-side second line 50b-2. Further, the plurality of roof-side third filaments 50b-3 respectively connect the roof-side first filaments 50b-1 and the roof-side second filaments 50b-2 diagonally so that the front side becomes higher.

In this way, the front side of the pillar-side first filament 50a-1 and the pillar-side second filament 50a-2, and the roof-side first filament 50b-1 and the roof-side second filament 50b-2 become higher on the front side. The reason for connecting them obliquely is to make it easy to take out from the mold after the completion of the molding in accordance with the rising direction of the upper mold when molding the respective mold forming portions 1d and 1e of the glass run.

Further, the roof-side convex portion 50b has a plurality of groove portions 50b-4 surrounded by the roof-side first linear filament 50b-1, the roof-side second linear filament 50b-2, and the roof-side third linear filament 50b-3. Has been formed.

The pillar-side protrusion 50a is hooked on the center pillar-side portion (see FIG. 4A) of the bent portion 60 of the door outer panel 101b. Further, the roof-side convex portion 50b is caught on a portion (not shown) on the roof side side of the bent portion 60. Then, due to these catches, the movement of the front mold forming portion 1d with respect to the door outer panel 101b, particularly the movement in the rear direction, is restricted.

Further, by forming a plurality of the above-mentioned groove portions 50a-4 and 50b-4 in the convex portion 50, the shape crack of the convex portion 50 is formed at the time of mold molding of the front die molding portion 1d (the same applies to the rear die molding portion 1e). Can be reduced. With respect to the groove portions 50a-4 and 50b-4, the shape, depth, number and the like of the opening portions can be arbitrarily changed in design (see FIG. 5A). However, when forming the groove portions 50a-4 and 50b-4 so that the catch of the convex portion 50 with respect to the bent portion 60 is not weakened, the depth, the number, and the opening of the convex portion 50 do not significantly reduce the rigidity of the convex portion 50. It is preferable to design the size of the part.

In the present embodiment, the protrusion 50 is formed only on the vehicle exterior side wall 12, but may be formed only on the vehicle interior side wall 11, for example. Further, for example, the convex portion 50 may be formed on both the vehicle interior side wall 11 and the vehicle exterior side wall 12.

Further, in the present embodiment, the convex portion 50 is composed of the pillar-side convex portion 50a and the roof-side convex portion 50b, but it is not essential that the roof-side convex portion 50b is formed. In other words, if the convex portion 50 is formed on at least the region on the side of the center pillar (pillar side portion corresponding to the arrangement position of the pillars) on either the vehicle interior side wall 11 or the vehicle exterior side wall 12. Good (see Figure 3).

Although not shown, a convex portion 50 (pillar-side convex portion 50a and roof-side convex portion 50b) is also formed on the vehicle exterior side wall 12 of the rear mold forming portion 1e of the glass run 1, and the door outer panel 101b is bent. The structure is such that it is hooked on the portion 60.

As shown in FIG. 4( a ), the front mold forming portion 1 d (site on the center pillar side) of the glass run 1 includes a bottom wall 10, a vehicle interior side wall 11, a vehicle exterior side wall 12, a vehicle interior seal lip 13, An outer seal lip portion 14, a vehicle interior design lip portion 15 and a vehicle exterior design protrusion portion (projection portion) 16 are provided.

The bottom wall 10 is a substantially plate-shaped portion that faces the end surface 102a of the door glass 102. Further, a substantially plate-shaped vehicle-inside side wall 11 extends from the vehicle-inside edge (side edge on the vehicle-inside) 10 a of the bottom wall 10 toward the center side of the door glass 102. Further, a substantially plate-shaped outer side wall 12 extends from the outer side edge (side edge on the outer side) 10b of the bottom wall 10 toward the center side of the door glass 102.

Due to the positional relationship between the vehicle interior side edge 10a and the vehicle exterior side edge 10b with respect to the bottom wall 10, the vehicle exterior side wall 12 is arranged outside the vehicle interior side wall 11 with the grass run 1 attached to the door frame 101. The bottom wall 10, the vehicle interior side wall 11, and the vehicle exterior side wall 12 form a portion having a substantially U-shaped cross section.

A pillar-side convex portion 50a is formed in a region on the side of the center pillar on the surface of the vehicle exterior side wall 12 that faces the door outer panel 101b. The pillar-side convex portion 50a comes into contact with the vehicle outer side surface of the door outer panel 101b in a state where the front mold forming portion 1d is attached to the front corner portion of the door frame 101. Further, when the roof-side extruded portion 1b is contracted from the roof portion of the door frame 101 due to the difference in linear expansion coefficient between the door frame 101 and the glass run 1, the pillar-side convex portion 50a is bent at the bent portion 60 ( The part on the center pillar side).

In consideration of the balance between the reliable catching of the bent portion 60 of the pillar-side convex portion 50a (the portion on the side of the center pillar) and the external appearance in the vicinity of the arrangement position of the vehicle exterior design protrusion 16 to be described later, FIG. As shown in c), the height H1 of the convex portion 50 from the first surface F1 is 1/2 or more of the height H2 of the bent portion 60 from the second surface F2, and the height H1 of the bent portion 60 is equal to or more than The height from the first surface F1 (root) is preferably H3 or less.

Here, the "first surface F1" refers to a surface of the vehicle exterior side wall 12 that faces the door outer panel 101b. The “first surface F1” is in contact with the 180° folded surface of the outer door panel 101b in FIG. 4B, and faces the 90° bent portion 60 of the outer door panel 101b in FIG. 4C. The “second surface F2” refers to the vehicle outer surface of the door outer panel 101b.

If the height H1 of the convex portion 50 from the first surface F1 is less than 1/2 of the height H2 of the bent portion 60 from the second surface F2, the convex portion 50 is not sufficiently caught by the bent portion 60, There is a high possibility that the glass run 1 (particularly, the front side molding portion 1d) will fall off. In that respect, as described above, the height H1 of the convex portion 50 from the first surface F1 is set to be 1/2 or more of the height H2 of the bent portion 60 from the second surface F2, so that the grass run 1 falls off. Possibility can be reduced.

In addition, when the height H1 of the convex portion 50 from the first surface F1 is higher than the height H3 of the vehicle exterior design protrusion 16 from the first surface F1, the protrusion 50 is arranged at the outermost position of the vehicle exterior design protrusion 16. The top portion of the door outer panel 101b is disposed inside (in some cases, significantly) the vehicle outer side surface of the door outer panel 101b. In this case, a step is formed between the top of the vehicle exterior design protrusion 16 and the vehicle outer surface of the door outer panel 101b, and the vehicle appearance (coherency) deteriorates. In that respect, as described above, by setting the height H1 of the convex portion 50 from the first surface F1 to be equal to or lower than the height H3 of the vehicle exterior design protrusion 16 from the first surface F1, the door outer panel 101b is obtained. It is possible to maintain a good appearance in the vicinity of the contact point with the exterior design protrusion 16.

The bent portion 60 (the portion on the side of the center pillar) is formed at the inner edge of the corner portion of the door outer panel 101b, and is a portion bent toward the center of the door glass 102 with respect to the door outer panel 101b. The bent portion 60 is not a portion specially provided for restricting the unintended movement of the grass run 1, but a portion generally formed in the structure of the slide door 100. Therefore, by using the bent portion 60, it is possible to realize the attachment structure of the grass run 1 that can regulate the unintended movement of the grass run 1 with a simple structure.

Here, the center (C/L) of the door glass 102 refers to the surface of the half thickness portion in the glass plate thickness direction from the vehicle outer side surface to the vehicle inner side surface of the door glass 102, as shown in FIG. And (b) are each shown by a dashed line.

An inner seal lip portion 13 is provided at an end of the inner side wall 11 on the center side of the door glass 102 so as to stand up toward the bottom wall 10 (curved in the figure). Further, an exterior seal lip portion 14 is provided at an end of the exterior side wall 12 on the side where the door glass 102 is disposed so as to stand up toward the bottom wall 10 (curved in the figure). ). The vehicle interior seal lip portion 13 is formed by connecting a fin-shaped vehicle interior elastic contact portion 13a that elastically contacts the door glass 102 and an vehicle interior connection portion 13b that connects the vehicle interior elastic contact portion 13a and the vehicle interior side wall 11. Has been done. Similarly, the vehicle outer seal lip portion 14 includes a fin-shaped vehicle outer side elastic contact portion 14 a that elastically contacts the door glass 102 and a vehicle outer side connection portion 14 b that connects the vehicle outer side elastic contact portion 14 a and the vehicle outer side wall 12. It is formed in a row.

The vehicle interior side seal lip portion 13 and the vehicle exterior seal lip portion 14 are such that the vehicle interior side elastic contact portion 13a and the vehicle exterior side elastic contact portion 14a elastically contact the vehicle interior side surface of the door glass 102 and the vehicle exterior side surface, respectively. Then, the space between both side surfaces of the door glass 102 and the door frame 101 is sealed.

Further, the root of the vehicle exterior seal lip portion 14 is recessed so that only the vehicle exterior connection portion 14b of the vehicle exterior seal lip portion 14 is thin.
