Description
Technical Field
The present invention relates to a glass run mounted along a window frame of an opening and closing door for a vehicle for guiding sliding movement (i.e., lifting and lowering) of a window panel (window glass) and for sealing a gap between the window panel and the window frame, and to a mounting structure of the glass run to a vehicle door.
Background
For example, patent document 1 relating to "a door structure for a vehicle" discloses a glass run and an attachment structure thereof as described above in fig. 1 to 3 thereof. That is, the sash 12 integrated with the outer panel 10 of the door includes an upper frame portion UF, a center pillar portion BP, and a corner portion formed at a crossing position of the upper frame portion and the center pillar portion, and the corner portion is provided with a sash recess 15. On the other hand, the glass run channel 20 includes a main body portion including a vehicle interior side wall portion 212, a vehicle exterior side wall portion 222, and a coupling portion 230 for coupling both the side wall portions, and a vehicle exterior side lip 225 for supporting the outer panel 10 with the side wall portion 222 is provided extending in the longitudinal direction on the vehicle exterior side wall portion 222. The projecting amount (or projecting width) of the vehicle exterior side lip 225 is substantially the same at the portion facing the upper frame portion and the center pillar portion of the sash, but the glass run convex portion 25 is formed by projecting outward in a large amount at the corner portion facing the corner portion of the sash (the portion bent at substantially right angle). When the glass run 20 is attached to (a sash portion of) a door, the outer side lip 225 including the glass run protrusion 25 is disposed so as to be laid on the outer side (vehicle outer side) of the outer panel 10 (see fig. 2). Further, the glass run protrusion 25 is fitted into the sash recess 15, whereby the positioning accuracy of the glass run 20 with respect to the sash 12 is improved (see fig. 3 and 1).

Disclosure of Invention
Technical problem to be solved by the invention
However, according to the above-described mounting structure of the glass run channel, when the vehicle outer side lip 225 is mounted on the outer side (vehicle outer side) of the outer panel 10, there is a fear that the following may occur: the outside lip 225 on which the glass run protrusion 25 is formed is recessed toward the inside of the window frame at the position of the window frame recess 15 provided at the corner of the window frame. That is, in the vehicle exterior lip 225, particularly the glass run convex portion 25 that greatly protrudes outward may be more likely to be recessed than other vehicle exterior lip portions. If a part of the vehicle exterior lip 225 (in this case, the glass run convex portion 25) is recessed toward the vehicle interior side, an unexpected gap may be generated between the vehicle exterior lip 225 and a garnish (see fig. 2 of patent document 1, garnish 30) disposed outside the vehicle exterior lip 225. The occurrence of this gap is also a cause of wind noise during traveling, and is not preferable.
The present invention aims to prevent a recess (deformation) from occurring in a vehicle outer side lip portion provided in a glass run when the glass run is attached to a window frame of a vehicle door, and to avoid as much as possible a trouble such as wind noise generated during traveling.
Means for solving the problems
A first aspect of the present invention is a glass run channel,
the glass run is a long glass run made of an elastic polymer material and is mounted along a window frame of a vehicle door having an upper frame, a vertical frame, and an inner corner portion formed between the upper frame and the vertical frame, for guiding sliding movement of a window panel,
the glass run is provided with: an upper edge portion mounted to an upper frame of the window frame; a vertical side portion mounted to a vertical frame of the window frame; and a die molding part which connects the upper side part and the longitudinal side part and is mounted on the inner corner part of the window frame,
the glass run channel includes, when viewed from a cross section intersecting the longitudinal direction: a base portion that faces an end surface of the window panel; an inside-vehicle-side wall portion and an outside-vehicle-side wall portion that are provided upright from both ends of the base portion in the width direction, respectively; and a vehicle exterior lip provided so as to protrude outward from a distal end of the vehicle exterior side wall portion toward a vehicle exterior,
the vehicle exterior lip extends along the longitudinal direction of the glass run, and when the glass run is attached to the sash, a part of the door panel of the door is covered with the upper frame, the vertical frame, and the inner corner of the sash, and a part of the vehicle exterior portion of the vehicle exterior lip is covered with the garnish attached to the vertical frame of the sash,
a corner R is formed on the outer lip of the mold forming part,
a thick portion is further formed on the vehicle exterior lip of the mold molding portion in the vicinity of the corner R, and a thickness T1 of the thick portion is thicker than a thickness T2 of a portion other than the thick portion in the vehicle exterior lip of the mold molding portion.
According to the first aspect, the rigidity is improved by forming the thick portion in the vehicle exterior lip of the mold forming portion, among the vehicle exterior lip extending in the longitudinal direction of the glass run. Therefore, when the glass run is attached to the window frame, even when the outer lip of the mold molding portion is placed on the door panel in the upper frame, the vertical frame, and the inner corner portion of the window frame, the outer lip of the mold molding portion can be prevented from being recessed toward the inside of the vehicle. This makes it possible to prevent or suppress wind noise and the like by avoiding as much as possible the occurrence of a gap between the vehicle exterior lip and the garnish covering the vehicle exterior lip from the outside.
In a second aspect of the present invention, in the glass run according to the first aspect,
the outboard lip of the mold forming portion has a fin portion disposed adjacent to the corner R, and the thick portion is disposed in a region of the fin portion.
According to the second aspect, the following effects are obtained in addition to the effects of the first aspect. That is, in the case where the fin portion is provided near the corner R of the vehicle exterior lip of the mold molding portion, if only the fin portion is provided, the vehicle exterior lip is likely to be recessed, but the recessed portion of the vehicle exterior lip can be prevented by providing the thick portion in the region of the fin portion.
In a third aspect of the present invention, in the glass run channel according to the second aspect,
the corner R is provided at a position where a first substantially horizontal vehicle exterior side lip portion, which is continuous with and located on an extension of the vehicle exterior side lip of the upper side portion, intersects a second substantially vertical vehicle exterior side lip portion, which is continuous with and located on an extension of the vehicle exterior side lip of the longitudinal side portion,
the fin portion is formed such that the first outboard lip portion protrudes further than a tip edge of the second outboard lip portion across the corner R.
A fourth aspect of the present invention is the glass run according to any one of the first to third aspects,
the thick portion is formed by filling the vehicle interior rear surface with a filler in the vehicle exterior lip of the mold molding portion.
According to the fourth aspect, in addition to the effects of the first to third aspects, the following effects are obtained. That is, when the thick portion is formed on the vehicle exterior lip of the mold molding portion, the vehicle interior rear surface is filled with a filler (a portion that is not easily visible from the vehicle exterior), so that the vehicle exterior surface (a portion that is easily visible from the vehicle exterior) on the opposite side of the vehicle interior rear surface can be maintained in a relatively flat state, and the appearance (design) is not impaired.
A fifth aspect of the present invention is the glass run according to any one of the first to fourth aspects, wherein the thick portion has a thickness distribution of: the central region has the thickest thickness, and the thickness gradually decreases from the central region toward the peripheral region.
According to the fifth aspect, in addition to the effects of the first to fourth aspects, the following effects are obtained. That is, in the glass run, when a mold molding portion for connecting the upper edge portion and the vertical edge portion is formed by injection molding, it is generally necessary to take into consideration sink marks that may occur during the curing of the resin. In this regard, in the present invention, the thick portion of the vehicle exterior side lip of the mold molding portion has a thickness distribution in which the thickness of the central region is the thickest and gradually decreases from the central region toward the outer peripheral region, and therefore, the occurrence of sink marks in the thick portion can be suppressed or alleviated.
A sixth aspect of the present invention is the glass run according to any one of the first to fifth aspects,
the corner R is provided at a position where a first substantially horizontal vehicle exterior side lip portion, which is continuous with and located on an extension of the vehicle exterior side lip of the upper side portion, intersects a second substantially vertical vehicle exterior side lip portion, which is continuous with and located on an extension of the vehicle exterior side lip of the longitudinal side portion,
the thick-walled portion is provided at a position where the first vehicle exterior side lip portion intersects the second vehicle exterior side lip portion.
A seventh aspect of the present invention is a mounting structure of a glass run to a door, including:
a door panel;
a window frame having an upper frame, a vertical frame, and an inner corner portion formed between the upper frame and the vertical frame as a frame body that borders a window portion of the door panel;
a glass run that is the glass run of any one of claims 1 to 6, mounted along the window frame for guiding sliding movement of a window panel; and
a garnish attached to at least the vertical frame of the window frame,
in the upper frame, the vertical frame, and the inner corner of the window frame, an outer lip of the glass run covers a part of the door panel,
in the vertical frame and the inner corner portion of the sash, the garnish covers a part of the vehicle exterior side lip of the glass run, and the vehicle exterior side surface of the vehicle exterior side lip of the glass run abuts against the garnish over the entire length of the garnish.
According to the seventh aspect, the same effects as those of the first to sixth aspects are obtained. That is, in the glass run used in the mounting structure, since the thick portion is formed at the outer side lip of the mold molding portion to improve rigidity, the outer side lip of the mold molding portion does not sink toward the inside of the vehicle even when the outer side lip is caught on the door panel in the upper frame, the vertical frame, and the inner corner portion of the window frame when the glass run is mounted to the window frame. Therefore, the outer surface of the outer lip of the glass run can be maintained in contact with the garnish without a gap over the entire length of the garnish in the vertical frame and the inner corner of the sash. As a result, a gap between the vehicle exterior lip and the garnish can be avoided, and wind noise and the like can be prevented or suppressed.
Effects of the invention
According to the present invention, when the glass run is attached to the sash of the door, it is possible to prevent the outer lip portion of the glass run from being dented (deformed), and to avoid as much as possible the occurrence of defects such as wind noise during traveling.

Detailed Description
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Fig. 1 shows a state in which a front door 1 as a door is viewed from the outside of the vehicle. As shown in fig. 1, a window frame 3 is integrally formed on a door panel 2 forming a front door 1. The sash 3 is a frame body that borders a window portion of the door panel 2, and the sash 3 includes at least: an upper frame 3a disposed close to the ceiling of the vehicle; a vertical frame 3b disposed along a center pillar that supports a roof of the vehicle; and an inner corner portion 3c (see fig. 2) formed between the upper frame 3a and the vertical frame 3 b. In the door panel 2, a glass run 10 is mounted, particularly along the window frame 3. Further, a garnish 4 (decorative member) is attached to at least the vertical frame 3b of the sash 3 so as to cover substantially the entire vertical frame 3b and a part of the glass run 10 from the outside.
The glass run 10 is an elongated member for guiding the sliding movement of the window panel 5, and is mainly made of an elastic polymer material. Examples of the elastic polymer material that can be used include TPE (thermoplastic elastomer) and rubber. In this embodiment, TPO (olefin thermoplastic elastomer) having a hardness of a80 is used.
As shown in fig. 1 to 3, the glass run 10 includes at least an upper side portion 11, a vertical side portion 12, and a mold molding portion 13 as a connecting portion connecting the upper side portion 11 and the vertical side portion 12 in a longitudinal direction. The upper side 11 is mainly attached to the upper frame 3a of the window frame. The vertical side portion 12 is mainly attached to the vertical frame 3b of the window frame. The upper side portion 11 and the vertical side portion 12 are formed linearly by extrusion molding.
On the other hand, the die forming portion 13 is mainly attached to the inner corner portion 3c of the window frame, and the die forming portion 13 is formed by injection molding after extrusion molding. Specifically, the distal end portion of the upper side portion 11 obtained by extrusion molding and the distal end portion of the vertical side portion 12 intersect at a predetermined angle (for example, 70 to 90 °) while maintaining a predetermined distance therebetween, and are assembled to the injection molding die. Then, an elastic polymer material is injected into the molding die and injection molding is performed, thereby forming the die molding portion 13 so that the overall shape of the glass run 10 is substantially determined. The mold molding portion 13 thus obtained connects the upper side portion 11 and the vertical side portion 12 while maintaining the crossing arrangement relationship between the upper side portion 11 and the vertical side portion 12.
Next, a basic structure (mainly, a cross-sectional structure) common to the three parts, i.e., the upper edge part 11, the vertical edge part 12, and the mold molding part 13 of the glass run 10, will be described with reference to fig. 4 and 5. As shown in these figures, the glass run 10 includes a base portion 14, and an inner side wall portion 15 and an outer side wall portion 16 that are provided upright from both ends in the width direction of the base portion 14, respectively, when viewed in a cross-sectional direction intersecting the longitudinal direction. The base bottom portion 14, the vehicle interior side wall portion 15, and the vehicle exterior side wall portion 16 are provided to extend in the longitudinal direction of the glass run 10. In the present embodiment, the vehicle interior side wall portion 15 is dimensioned to be relatively long (or tall) and the vehicle exterior side wall portion 16 is dimensioned to be relatively short (or low). The base portion 14 is also a portion that connects the base end portion of the inside side wall portion 15 and the base end portion of the outside side wall portion 16 to each other and faces or contacts the end surface of the window panel 5.
As shown in fig. 4, for example, an outer seal lip 21 that protrudes toward the inside of the vehicle is provided at a distal end portion of the vehicle exterior side wall portion 16. The outer seal lip 21 abuts against the vehicle exterior side surface of the window panel 5 to seal the end of the window panel 5. On the other hand, an inner seal lip 22 projecting toward the vehicle exterior side is provided in the middle of the vehicle interior side wall portion 15. The inner seal lip 22 seals the end of the window panel 5 by abutting against the inside surface of the window panel 5. The outer and inner sealing lips 21, 22 are in close opposed relationship to each other, with the end of the window panel 5 being clamped between them.
A vehicle interior lip 23 is provided at a distal end portion of the vehicle interior side wall portion 15, and the vehicle interior lip 23 is formed so as to protrude from the distal end portion toward a side (i.e., vehicle interior side) opposite to the interior seal lip 22 and to be folded back along the vehicle interior side wall portion 15. The vehicle interior lip 23 extends in the longitudinal direction of the glass run 10, similarly to the vehicle interior side wall portion 15. The vehicle interior lip 23 mainly sandwiches a part of the door panel 2 with the vehicle interior side wall portion 15.
As shown in fig. 4 and 5, a vehicle exterior lip 24 is provided at a distal end portion of the vehicle exterior side wall portion 16, and the vehicle exterior lip 24 is formed so as to protrude from the distal end portion to a side opposite to the outer seal lip 21 (i.e., vehicle exterior side) and to be folded back along the vehicle exterior side wall portion 16. The vehicle exterior lip 24 extends in the longitudinal direction of the glass run 10, similarly to the vehicle exterior side wall portion 16. The vehicle exterior lip 24 also sandwiches a part of the door panel 2 with the vehicle exterior side wall portion 16. When the glass run 10 is mounted on the sash 3 of the door, the outer lip 24 covers a part of the door panel 2 in the upper frame 3a, the vertical frame 3b, and the inner corner 3c of the sash. Further, a part of the vehicle exterior side portion of the vehicle exterior side lip 24 is covered with the garnish 4 attached to the vertical frame 3b of the sash.
As shown in FIG. 3 (and FIG. 2), a "corner R" (denoted by reference numeral 25) is formed at the vehicle exterior side lip 24 of the mold molding portion 13. The corner R25 is an edge or a peripheral edge portion having a contour curved in a substantially arc shape in the vicinity of the root of the vehicle exterior lip 24. As shown in fig. 3, the corner R25 is provided at a position where a substantially horizontal vehicle exterior side lip portion 24h intersects a substantially vertical vehicle exterior side lip portion 24v, the vehicle exterior side lip portion 24h being continuous with the vehicle exterior side lip 24 of the top side portion 11 and being located on an extension thereof (an extension toward the left side of the paper in the drawing), the vehicle exterior side lip portion 24v being continuous with the vehicle exterior side lip 24 of the longitudinal side portion 12 and being located on an extension thereof (an extension toward the upper side of the paper in the drawing). The corner R25 smoothly connects or connects the edge of the substantially horizontal vehicle exterior lip portion 24h and the edge of the substantially vertical vehicle exterior lip portion 24 v.
In the present embodiment, as shown in fig. 2 and 3, a fin portion 27 is provided near a corner R25 on the vehicle exterior lip 24 of the mold molding portion 13. The fin portion 27 is formed substantially to have a portion protruding outward from the inner corner 3c toward the outer corner region of the window frame. More specifically, as shown in fig. 3, the fin portion 27 is formed so that the substantially horizontal vehicle exterior side lip portion 24h extends further to the left side than the tip edge of the substantially vertical vehicle exterior side lip portion 24v across the corner R25. Therefore, the substantially horizontal upper edge 27a of the fin portion 27 is aligned substantially linearly with the distal edge (upper edge in fig. 3) of the substantially horizontal vehicle exterior side lip portion 24 h.
In the present embodiment, as shown in fig. 3 and 5, the thick portion 28 is formed in the region of the fin portion 27 in the vehicle exterior side lip 24 of the mold molding portion 13. Thick portion 28 is disposed in the vicinity of corner R25 (right left position of corner R in fig. 3).
The thick portion 28 is a portion formed to be particularly thick in the vehicle exterior lip 24 of the mold molding portion 13, as described in the text. When the thickness of the thickest part of the thick portion 28 is T1 (see fig. 5) and the thickness of the other part (non-thick portion) than the thick portion is T2 (see fig. 4), the thickness of the thick portion is T3578
T1＝2×T2
The wall thickness is set. That is, the maximum wall thickness T1 of the thick-walled portion 28 is set to a thickness of about 2 times the wall thickness T2 of the non-thick-walled portion.
The thick portion 28 is simultaneously molded at the time of injection molding of the mold molding portion 13, but when the thick portion 28 is simultaneously molded, the thickness of the thick portion 28 is secured by filling the vehicle interior rear surface (surface that can face the door panel 2) of the vehicle exterior side surface (side surface opposite to the vehicle interior rear surface) and the vehicle interior rear surface (surface that can face the door panel 2) of the vehicle exterior side lip 24. Therefore, the vehicle exterior surface of the vehicle exterior lip 24 of the mold molding portion 13 can be maintained in a relatively flat state without impairing the appearance.
In the case of the thick portion 28 formed by filling the vehicle interior rear surface of the vehicle exterior lip 24 (or the fin portion 27), the following thickness distribution is formed: the central region has the thickest thickness, and the thickness gradually decreases from the central region toward the peripheral region.
Fig. 6(a) schematically shows the thickness distribution of the thick-walled portion 28 in the fin portion 27. In fig. 6(a), since the fin portion 27 is viewed from the vehicle exterior side, the outline of the thick portion 28 is indicated by a thick broken line. The 3 thin dashed lines L1, L2, L3 drawn in a similar shape concentric with the thick dashed line (the outline of the thick-walled portion 28) are contour lines indicating the height (i.e., thickness) of the protrusion from the vehicle interior rear surface. That is, the region surrounded by the broken line L1 is thickest, and the thickness gradually decreases toward the outer peripheral region in the case of L1 → L2 → L3. When having such a thickness distribution, the change in thickness at the thick portion 28 becomes gentle in a mountain shape as shown in the assumed cross section of fig. 6 (B). In such a case, even if the sink mark 31 shown by the imaginary line is generated on the side opposite to the filler side immediately after the injection molding, the degree of the sink mark 31 is small, and the deterioration of the appearance can be suppressed.
Next, a usage of the glass run of the present embodiment will be described.
As shown in fig. 2, 4, and 5, when the glass run 10 is mounted to the sash 3, the door panel 2 is engaged between the vehicle interior lip 23 and the vehicle interior side wall portion 15, and between the vehicle exterior lip 24 and the vehicle exterior side wall portion 16, thereby completing the mounting of the glass run 10 to the sash 3. In this attached state, the outer lip 24 of the door panel 2 is in a posture of covering a part of the door panel from above (or from the outside of the vehicle) at least in the upper frame 3a, the vertical frame 3b, and the inner corner 3c of the window frame 3.
Next, the garnish 4 is attached to the vertical frame 3b of the sash 3 to which the glass run 10 is attached. In this attached state, the garnish 4 covers a part of the outer lip 24 of the glass run in the vertical frame 3b and the inner corner 3c of the sash. At the same time, the vehicle exterior surface of the vehicle exterior lip 24 of the glass run abuts against the garnish 4 over the entire length of the garnish 4. In order to realize or ensure the "abutment over the entire length of the garnish", the thick portion 28 provided in the fin portion 27 greatly contributes (for reasons described later).
In the present embodiment, as shown in fig. 2, an upper edge line 24UL of the vehicle exterior lip 24 of the upper edge portion 11 of the glass run channel and an upper edge line 4UL of the garnish 4 are designed to be substantially horizontally aligned linearly. Therefore, the design around the window frame is excellent.
Unlike the present embodiment, in which the fin portion 27 is provided in the outer corner region of the mold molding portion 13 of the glass run channel, it is clear that, when the fin portion 27 is not provided with the thick portion 28, the (outer surface of the) outer lip 24 tends to be recessed toward the inside of the vehicle in the region surrounded by the oval one-dot chain line B in fig. 2. If this recess occurs, a gap is generated between the vehicle exterior lip 24 and the garnish 4, and this gap causes a problem that wind noise is generated during traveling.
In this regard, in the present embodiment, since the thick portion 28 is formed on the outer lip 24 (i.e., the fin portion 27) of the mold molded portion 13 to enhance the rigidity, the outer lip 24 of the mold molded portion 13 does not sink toward the inside of the vehicle even when the outer lip 24 is mounted on the door panel 2 in the upper frame 3a, the vertical frame 3b, and the inner corner portion 3c of the window frame when the glass run 10 is mounted on the window frame 3. Therefore, in the vertical frame 3b and the inner corner 3c of the sash, the vehicle exterior surface of the vehicle exterior lip 24 of the glass run can be maintained in contact with the garnish 4 without a gap over the entire length of the garnish 4. As a result, a gap between the exterior lip 24 and the garnish 4 can be avoided, and wind noise and the like can be prevented or suppressed.
[ modification example ]
The embodiments of the present invention are not limited to the above-described embodiments, and can be modified as follows.
In the embodiment of fig. 1 to 6, the fin portion 27 is provided in the outer corner region of the vehicle exterior side lip 24 of the mold molding portion 13, and the fin portion 27 has a portion protruding outward, but the portion protruding outward is not essential to the present invention. For example, as shown in fig. 7, a glass run having no portion protruding outward can be applied to the present invention also to the outer corner region of the vehicle exterior lip 24 of the mold molding portion 13. As shown in fig. 7, it is clear that the simplified vehicle exterior side lip 24 of the mold molding portion 13 is likely to have a recess toward the vehicle interior side at a position slightly below the corner R25 (this position may be said to be in the vicinity of the corner R). Therefore, by forming the thick portion 28 in the vicinity of the corner R at a position slightly below the corner R, it is possible to prevent the recess of the vehicle exterior side lip 24 and prevent or suppress wind noise and the like.
