Description

  The present invention relates to a glass run.

  Generally, a glass run is provided along the inner periphery of a door frame of an automobile. When viewed from the cross-sectional direction, the glass run is provided with a substantially U-shaped main body portion including a base portion, a vehicle inner side wall portion and a vehicle outer side wall portion extending from the base portion, and substantially tip ends of both side wall portions. The vehicle interior seal lip and the vehicle exterior seal lip extending from the vehicle body toward the inside of the main body. The glass run is sealed so that the body portion is attached to a mounting portion provided along the inner periphery of the door frame, and the peripheral portions of the inner and outer surfaces of the door glass moving up and down are sandwiched by both seal lips. .

  The glass run includes an upper side corresponding to the upper edge of the door glass, and a front vertical side and a rear vertical side corresponding to the front and rear vertical edges of the door glass, which are formed in a substantially linear shape. And the mold forming part that connects the ends of the extruded part at a predetermined angle.

  By the way, when the glass run is composed of an extrusion molding part and a molding part, the connecting line between the extrusion molding part and the molding part appears on the appearance, and this may lead to a decrease in appearance quality. There is. In addition, the composition material may be different between the extrusion molding part and the mold molding part, and there is a risk that the surface color and gloss will be greatly different. There is a risk of being invited.

  On the other hand, a glass run in which the entire longitudinal direction is integrally formed by molding has also been proposed (see, for example, Patent Document 1). By adopting the technique of Patent Document 1, it is possible to avoid problems such as partial differences in color and gloss in the longitudinal direction of the glass run.

  By the way, in the glass run, foreign matter such as dust and muddy water may enter the inside of the main body. In this case, there is a possibility that the foreign matter is pushed up by the end face of the rising door glass and accumulated on the base portion near the upper end portion of the vertical side portion. As described above, if foreign matter accumulates on the base near the upper end of the vertical side, abnormal noise may be generated when the accumulated foreign matter and the door glass come into sliding contact.

  On the other hand, there is a technique in which a plurality of guide grooves for discharging foreign matters extending along the longitudinal direction of the glass run are provided in the base (see, for example, Patent Document 2).

JP 2008-149739 Japanese Patent No. 3336926

  By adopting the technique of Patent Document 2, when the door glass is raised and lowered, the foreign matter that has entered the inside of the main body is dropped into the guide groove, and as a result, the foreign matter is present at the base near the upper end of the vertical side portion. The situation where it accumulates can be suppressed. However, in Patent Document 2, in order to remove foreign matter from a portion facing the end surface of the door glass at the base, that is, a portion that may come into contact with the door glass, the guide groove is formed at the lower end of the vertical side portion. It is necessary to discharge the foreign matter from the lower end portion of the vertical side portion through the guide groove.

  However, as in Patent Document 1 described above, when trying to form a guide groove extending to the lower end portion of the vertical side portion along the longitudinal direction of the glass run with respect to the glass run in which the entire longitudinal direction is molded, There is a risk of complication of the mold.

  The present invention has been made in view of the above circumstances, and its purpose is to prevent foreign matter from accumulating on the inside of the main body without increasing the complexity of the mold while improving the appearance quality and the like. It is to provide a glass run that can be used.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. It has a base portion, a vehicle inner side wall portion and a vehicle outer side wall portion extending from the base portion, has a substantially U-shaped cross section, and is attached to a mounting portion provided along the inner periphery of the vehicle door frame. Main body
A vehicle inner side seal lip and a vehicle outer side seal lip extending from substantially the front ends of the vehicle inner side wall and the vehicle outer side wall to the inside of the main body,
A stretchable connecting portion formed in the base portion, formed in a substantially V-shaped cross section in an elongated state at the time of molding, and formed in a substantially I-shaped cross section in a contracted state at the time of attachment;
The entire longitudinal direction including the upper side corresponding to the upper edge of the door glass that moves up and down and the front vertical side and rear vertical side corresponding to the front edge and rear edge of the door glass is integrated by molding. And the connecting portion is a glass run formed continuously over the entire longitudinal direction of the main body,
The connecting part is formed at a position deviating from the facing part of the end face of the door glass in the base part,
Mud or the like extending in a direction obliquely intersecting the sliding direction of the door glass only in the vicinity of the upper end of the inner side surface of the base portion of at least one of the front vertical side portion and the rear vertical side portion. A guide groove for discharging foreign matter is formed,
The guide groove is formed in at least a portion of the base portion facing the end surface of the door glass, and the guide groove extends from a lower end portion of the guide groove formed in the facing portion. A glass run that is also formed on the side of the part.

  According to the means 1, since the entire longitudinal direction of the glass run is integrally formed by molding, for example, a glass run configured by connecting a plurality of molded bodies including an extruded molded body in the longitudinal direction, and In contrast, it is possible to avoid a situation in which a connecting line connecting adjacent molded bodies appears in the appearance. In addition, it is possible to avoid a situation in which a difference in color / gloss partially occurs in the longitudinal direction of the glass run. As a result, the appearance quality is improved.

  Further, in this means, a foreign material discharge guide groove extending in a direction obliquely intersecting with the sliding direction of the door glass is formed on the inner side surface of the base portion in the vicinity of the upper end portion of the vertical side portion. ing. For this reason, even if foreign matter such as dust or mud that has entered the inside of the main body is pushed up by the end surface of the rising door glass, the foreign matter is discharged only in the vicinity of the upper end of the vertical side portion. The guide groove eliminates the side of the base portion facing the door glass, that is, the position where it does not contact the door glass. Therefore, in the vicinity of the upper end portion of the vertical side portion, it is possible to prevent foreign matter from accumulating on the portion of the base portion facing the end face of the door glass, and abnormal noise is generated when the door glass slides on the accumulated foreign matter. It is possible to prevent such a situation from occurring. In addition, it is possible to avoid a situation where the door glass gets on the foreign matter accumulated and the sealing performance and sound insulation performance are lowered.

  Further, in this means, since the entire longitudinal direction of the glass run is formed by molding, the guide groove can be formed directly (integrally) in the base portion during molding. Therefore, compared to a configuration in which a guide groove is provided by attaching another member to the inner side surface of the base part (another member in which the guide groove is formed is attached to the base part), manufacturing workability is improved, glass The weight of the run can be reduced and the size can be reduced. Furthermore, it is possible to avoid a situation in which another member protruding inward from the inner side surface of the base and the door glass are in pressure contact with each other and the sliding property of the door glass is lowered.

  In this means, the guide groove is formed only in the vicinity of the upper end of the vertical side. For this reason, in a glass run in which the entire longitudinal direction is formed by mold forming, for example, compared to the case where guide grooves are formed in the entire longitudinal direction of the vertical side portion, simplification of the mold, and hence the labor involved in the manufacture of the mold The cost can be reduced. In addition, compared with the case where the guide groove is formed in the entire longitudinal direction of the vertical side portion, when the door glass moves up and down, the end surface of the door glass comes into sliding contact with the portion between the guide grooves in the base portion. It is possible to suppress a situation in which the sliding performance of the door glass is reduced.

  Further, the guide groove extends in a direction that obliquely intersects the sliding direction of the door glass. For this reason, for example, compared with the case where the guide groove extends along the longitudinal direction of the vertical side portion, it is possible to expect the effect of scraping and scraping off the foreign matter pushed up by the end face of the door glass in the guide groove. . In addition, since the guide groove extends continuously, not intermittently, in the thickness direction of the door glass, the foreign matter pushed up on the end face of the door glass can be more reliably removed. Therefore, even when the guide groove is provided only in the vicinity of the upper end portion of the vertical side portion, the effect of preventing the accumulation of foreign matters at the upper end portion of the vertical side portion is reliably exhibited.

  In addition, the guide groove extends in the direction intersecting the sliding direction of the door glass, so that the guide groove enters the guide groove as compared with the case where the guide groove extends along the longitudinal direction of the vertical side portion. It is possible to shorten the moving distance of the foreign matter until the foreign matter is removed from the portion of the base portion facing the end surface of the door glass to a position where it does not contact the end surface of the door glass. Accordingly, the foreign matter can be removed relatively quickly from the portion of the base portion facing the door glass, and the movement of the foreign matter is suspended in the middle of the portion of the base portion facing the door glass (such as mud solidifies). Such a fear can be suppressed.

  It should be noted that the two seal lips can be sufficiently separated by molding the glass run with the connecting portion extended. For this reason, in order to maintain the holding strength of the mold (core) for molding the inner surface of the main body, etc., it is necessary to have a developed shape that greatly widens the ends of the vehicle inner side wall and the vehicle outer side wall. Disappears. Therefore, when the door is attached to the attachment portion, it is not necessary to rotate and deform from the developed shape.Therefore, there is no surplus in the corner portion or the like, the seal lip meandering, and the wrinkle is not generated. It is possible to stabilize the mounting state and improve the sealing performance.

  Further, since the glass run is integrally formed (the base, the vehicle inner side wall, the vehicle outer side wall, the vehicle inner side seal lip, the vehicle outer side seal lip, etc. are formed in a continuous manner through the connecting portion), Compared to the manufacture of glass runs that are formed by connecting a plurality of molded bodies including extruded molded bodies in the longitudinal direction, the entire manufacturing facility can be simplified and the manufacturing workability can be improved. Productivity can be improved. In particular, since the connecting portion is formed in the entire longitudinal direction of the glass run, for example, in the glass run described in Japanese Patent Application Laid-Open No. 2008-149739 in which the connecting portion is partially provided in the longitudinal direction of the glass run. Compared to the configuration, when filling the mold cavity with the constituent material, it is necessary to form the constituent material so that the constituent material can be easily spread over the entire cavity, and the engaging portions other than the connecting portion can be engaged. In addition, it is possible to improve manufacturing workability (shortening manufacturing time), suppress molding defects, simplify the mold apparatus, and the like.

  Furthermore, for example, when the connecting portion is partially provided in the longitudinal direction of the glass run, in a state where the connecting portion is contracted, the connecting portion is caused by the thickness of the connecting portion or the repulsive force of the connecting portion. There is a possibility that the width of the base portion changes between the existing portion and the non-existing portion (the amount of contraction of the base portion toward the inside and outside of the vehicle changes). On the other hand, according to this means, the connection part is provided in the whole longitudinal direction of the glass run (main body part). For this reason, the lateral width of the base portion can be made substantially uniform throughout the entire length of the glass run, and the attachment state can be stabilized.

  In addition, since the connecting portion is provided at a position away from the facing portion of the end surface of the door glass in the base portion, for example, when the connecting portion protrudes from the base portion to the inner peripheral side of the main body portion, the connecting portion is connected. It is possible to prevent the possibility of inconveniences such as an increase in resistance when the door glass slides due to the portion interfering with the door glass. In addition, it is possible to avoid a situation in which the guide groove is divided in the vehicle inside / outside direction by the connecting portion.

  Mean 2. The glass run according to means 1, wherein the guide groove is inclined downward toward the vehicle exterior.

  According to the means 2, foreign matter such as muddy water that has entered the guide groove is guided to the outside of the vehicle by the inclination of the guide groove. Accordingly, it is possible to more reliably prevent a situation in which a foreign object enters the indoor side.

  Means 3. 3. The glass run according to means 1 or 2, wherein the guide grooves are provided in parallel with each other and 3 to 5 strips spaced apart from each other in the sliding direction of the door glass.

  According to the means 3, since the guide grooves are provided at 3 to 5 strips at a predetermined distance from each other in the sliding direction of the door glass, an assembly error or molding error of the door glass and / or glass run occurs. In such a case, the error can be absorbed, and the function and effect of the means 1 can be reliably achieved. In addition, by providing at least three guide grooves, a position assuming that the above error does not occur, a position assuming an error that the door glass is shifted upward, a position assuming an error that the door glass is shifted downward A guide groove can be formed respectively. Therefore, the above-described effects can be achieved more reliably.

  Furthermore, for example, when the guide groove is formed in a relatively wide range in the sliding direction of the door glass, there is a concern that the amount of sliding contact with the door glass at a predetermined portion between the guide grooves is increased. That is, compared with the part located 1 cm below the upper end part of the vertical side part, the part located 2 cm below the upper end part of the vertical side part until the door glass completely rises after contacting the rising door glass. More than the door glass (from the state where the door glass is fully raised until the door glass is lowered and no longer contacts the door glass). And when the amount of sliding contact between the portions between the guide grooves that are relatively easily deformed and the door glass increases, there is a concern that abnormal noise is likely to occur due to sliding contact. In addition, even when the distance between each guide groove is narrow, the portion between the guide grooves is more easily deformed in the sliding direction of the door glass, and abnormal noise occurs when the door glass and the portion between the guide grooves are in sliding contact. There is a concern that it is likely to occur. On the other hand, in this means 3, since the guide grooves are 5 or less and the plurality of guide grooves extend in parallel with each other, the inner diameter of each guide groove is ensured so that foreign matter can be reliably guided. A plurality of guide grooves can be formed so as to avoid the above problems.

Means 4. On the inner peripheral side of the main body portion of the vertical side portion where the guide groove is formed, a guide groove extending to the lower end portion of the vertical side portion along the side portion of the base portion is formed,
The glass run according to any one of means 1 to 3, wherein the guide groove communicates with the guide groove.

  According to the means 4, foreign matter such as muddy water guided to the side of the base by the guide groove can be guided to the lower end of the vertical side by the guide groove. Therefore, the foreign matter can be discharged more reliably to the outside of the glass run. In addition, when the foreign matter excluded from the portion facing the end surface of the base door glass by the guide groove to the side of the base portion is moved downward, the end surface of the base door glass It is possible to suppress a situation in which it moves to the opposite part side of the door and results in being pushed up again by the end face of the rising door glass.

  Furthermore, for example, when the guide groove is formed in a glass run in which the end portions of the extrusion-molded portion are connected to each other by a mold forming portion at a predetermined angle, the guide groove formed in the mold forming portion. In addition, there is a concern that a step is formed at a boundary portion (joint) with the guide groove formed in the extrusion molding portion, and there is a possibility that foreign matters are likely to be accumulated at the step. On the other hand, as described in the means 1, the entire length of the glass run in the longitudinal direction is formed by molding, so that foreign matters can be discharged relatively smoothly through the guide groove.

  Means 5. The guide groove is formed along either the side portion on the vehicle inner side of the base portion or the side portion on the vehicle outer side of the base portion, and the lower end portion of the guide groove and the guide groove are 5. The glass run according to means 4, which is in communication.

  According to the means 5, the guide groove is formed along the side portion on the vehicle inner side of the base portion, and the mold is simplified as compared with the case where the guide groove is formed along the side portion on the vehicle outer side of the base portion. As a result, it is possible to reduce labor and cost for manufacturing the mold.

  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIG. 1, a front door (hereinafter simply referred to as “door 1”) that can be opened and closed at an opening for a door of an automobile includes a door glass G that can be raised and lowered, and an outer peripheral shape of the door glass G. And a glass run 5 that guides the raising and lowering of the door glass G and seals between the peripheral edge of the door glass G and the door frame 2.

  As shown in FIG. 2, the glass run 5 is formed on the upper side portion 6 corresponding to the upper edge portion of the door glass G, the front vertical side portion 7 corresponding to the front edge portion of the door glass G, and the rear edge portion of the door glass G. A corresponding rear vertical side portion 8 is formed. In this embodiment, the glass run 5 is integrally formed in the entire length direction including the upper side portion 6, the front vertical side portion 7, and the rear vertical side portion 8 by a mold apparatus (not shown). Then, a sash portion DS having a substantially U-shaped cross section formed along the outer periphery of the window portion W, and a cross section provided in the door panel 3 so as to extend downward in the longitudinal sides before and after the sash portion DS. The glass run 5 is attached to the inner periphery of the U-shaped channel portion DC. In the present embodiment, the glass run 5 is made of an olefinic thermoplastic elastomer (TPO), and the olefinic thermoplastic elastomer is preferably a dynamic crosslinking type (TPV). In the present embodiment, the sash part DS and the channel part DC correspond to the attachment part.

  As shown in FIG. 3, the upper side portion 6 corresponding to the upper edge portion of the door glass G includes a base portion 14, a vehicle outer side wall portion 15 and a vehicle inner side wall portion 16 extending from the base portion 14. A body portion 11 that is substantially U-shaped and is fitted into the sash portion DS, a vehicle outer side seal lip 12 that extends from the tip of the vehicle outer side wall portion 15 toward the vehicle inner side and the base portion 14 side, and a vehicle inner side wall portion 16. And a vehicle inner side seal lip 13 extending toward the vehicle outer side and the base portion 14 side. In a state where the window W is closed by the door glass G, the vehicle outer side seal lip 12 is pressed against the outer side surface (vehicle outer side surface) of the door glass G, and the vehicle inner side seal lip 13 is in contact with the inner side of the door glass G. It is in pressure contact with the side surface (surface inside the vehicle). Thereby, the vehicle exterior side and vehicle interior side of the door glass G are each sealed.

  Further, an exterior design lip 17 extending from the exterior side wall 15 toward the exterior of the vehicle and an interior design lip 18 extending from the interior side wall 16 toward the interior of the vehicle are provided. Further, a draining lip 19 that protrudes from the base portion 14 is provided at a vehicle outer side portion of the outer side surface of the base portion 14 (surface on the outer peripheral side of the main body portion 11). The draining lip 19 abuts against the sash portion DS when the glass run 5 is attached, and prevents rainwater and the like from entering the inside of the vehicle through the space between the glass run 5 and the sash portion DS. The vehicle exterior seal lip 12 is smaller (shorter) than the vehicle interior seal lip 13. As a result, the door glass G is brought to the outside of the vehicle and flash surface formation is achieved.

  In the present embodiment, the base portion 14 has a connecting portion 21 formed so that the lateral width of the base portion 14 can be changed between when the mold is molded and when the base portion 14 is attached to the sash portion DS and the channel portion DC. Is provided. The base portion 14 of the present embodiment is divided into a vehicle outer side portion (vehicle outer base portion 14a) and a vehicle inner side portion (vehicle inner base portion 14b) with the connecting portion 21 interposed therebetween.

As shown in FIG. 4, the connecting portion 21 is formed into a substantially V-shaped cross section that is convex on the inner peripheral side of the main body portion 11 by molding, and can be expanded and contracted in the in-vehicle outward direction (in the thickness direction of the door 1). As shown in FIG. 3, when the connecting portion 21 is contracted (folded), it is attached to the sash portion DS in a substantially I-shaped cross section. Moreover, the connection part 21 of this embodiment is a vehicle inner side (extension line along the inner side surface of the door glass G among the base parts 14 so that it may not interfere with the raising / lowering of the door glass G). It is formed on the vehicle inner side from the intersecting position, and the connecting portion 21 does not contact (interfere) with the door glass G that has entered the inside of the main body portion 11.

  Further, the first variable portion 21a and the second variable portion 21b extend substantially linearly, and as shown in FIG. 3, when the connecting portion 21 is contracted (folded), the first variable portion 21a and the second variable portion 21b 2 The variable portion 21b is in contact with the surface, and the connecting portion 21 is linear along the inner side surface (vehicle outer surface) of the vehicle inner side wall portion 16 (almost with respect to the inner side surface of the base portion 14). (Vertically). Furthermore, in this embodiment, the 1st variable part 21a and the 2nd variable part 21b are extended from the site | part of the outer peripheral side of the main-body part 11 of the mutually opposing surface among the vehicle outer base part 14a and the vehicle inner base part 14b. In a state where the connecting portion 21 is contracted, the base side portions of the first variable portion 21a and the second variable portion 21b are sandwiched between the vehicle outer base portion 14a and the vehicle inner base portion 14b. .

  Moreover, the thickness of the 1st variable part 21a and the 2nd variable part 21b is thinner than other parts (vehicle exterior base part 14a etc.), and is 1.0 mm in this embodiment, respectively. . Furthermore, as shown in FIG. 4, a groove-like portion 24 is formed along the boundary between the first variable portion 21 a and the second variable portion 21 b on the inferior angle side of the connecting portion 21. The thickness of the tip portion (near the boundary between the first variable portion 21a and the second variable portion 21b) is thinner than other portions. Therefore, as shown in FIG. 3, even when the connecting portion 21 is contracted (folded), the tip end portion of the connecting portion 21 (near the boundary portion between the first variable portion 21a and the second variable portion 21b) swells. Instead, the outer surface and the inner surface of the connecting portion 21 are substantially flat.

  In addition, in the present embodiment, in mold forming, the distance between the vehicle outer base portion 14a and the vehicle inner base portion 14b is formed so as to be constant in any part of the glass run 5 in the longitudinal direction. As described above, the first variable portion 21a and the second variable portion 21b extend from the surfaces of the vehicle outer base portion 14a and the vehicle inner base portion 14b that face each other. The position of the root portion of the variable portion 21a (the connection portion with the vehicle outer base portion 14a) and the position of the root portion of the second variable portion 21b (the connection portion with the vehicle inner base portion 14b) are in the longitudinal direction of the glass run 5. It becomes the same position in any part. Further, the position of the boundary portion between the first variable portion 21 a and the second variable portion 21 b in the vehicle inside / outside direction is shaped so as to be the same in any portion in the longitudinal direction of the glass run 5. In addition, when the first variable portion 21a and the second variable portion 21b are fixed (adhered) in a state where they are in contact with each other, the contracted state of the connecting portion 21 is maintained and the attachment to the sash portion DS or the like is easy. become.

Further, as shown in FIG. 11, the rear vertical side portion 8 includes a vehicle at a portion slightly lower than the central portion in the vertical direction (the central portion in the height direction of the window portion W) among the portions attached to the sash portion DS. A built-up portion 32c is provided so as to connect a portion on the distal end side of the inner side wall portion 16 and a portion on the root portion side of the vehicle interior seal lip 13. As shown in FIG. 12, the front vertical side portion 7 includes a portion on the front end side of the vehicle outer side wall portion 15 and a vehicle outer side seal lip 12 at a substantially central portion in the vertical direction among the portions attached to the sash portion DS. The built-up part 32d provided so that it may connect is provided. By providing the built-up portions 32a, 32b, 32c, and 32d in this way, the door glass G that closes the window portion W is inclined as desired (in the vertical direction, tilted upward toward the vehicle interior, and in the front-rear direction). It is adjusted so that it leans toward the inside of the vehicle toward the front.

  As shown in FIGS. 13 to 15, in the present embodiment, the inner side surface of the base portion 14 of the front vertical side portion 7 is obliquely intersected with the sliding direction of the door glass G only in the vicinity of the upper end portion. A guide groove 41 is formed for discharging foreign matter extending in the direction of the movement. The guide groove 41 extends obliquely downward toward the vehicle outer side from the vehicle inner side portion of the vehicle outer side base portion 14a to the vehicle side side portion. Three guide grooves 41 are provided in parallel to each other and at a predetermined distance from each other in the sliding direction of the door glass G (longitudinal direction of the front vertical side portion 7). In the present embodiment, a position assuming no assembly error or molding error of the door glass G and / or glass run 5, a position assuming an error that the door glass G shifts upward, and the door glass G on the lower side. A guide groove 41 is formed at each position where a deviation error is assumed. In addition, when the glass run 5 is molded, the guide groove 41 is formed directly (integrally) with respect to the inner side surface of the vehicle exterior base portion 14a at the same time as the base portion 14 is formed. Further, the inner side surface of the vehicle exterior base portion 14a is the same in the outer peripheral direction of the door frame 2 (the same surface) in the peripheral portion of the guide groove 41 (the portion between the guide grooves 41). ing. In addition, the end surface of the door glass G in the state which approached the inner side of the main-body part 11 is a vehicle inner side rather than the vehicle side side part of the vehicle outside base part 14a, and the vehicle interior side side part. It comes to face the part. In addition, the guide groove 41 has a substantially semicircular cross section.

  Furthermore, on the inner peripheral side of the main body portion 11 of the front vertical side portion 7, the front vertical side portion 7 extends from the upper end portion along the boundary between the vehicle outer side base portion 14 a and the vehicle inner side wall portion 15. A guide groove 42 is formed which extends to the lower end. A lower end portion (vehicle outer end portion) of each guide groove 41 communicates with the guide groove 42.

  As described above in detail, according to the present embodiment, since the entire longitudinal direction of the glass run 5 is integrally formed by molding, for example, a plurality of molded bodies including an extruded molded body are connected in the longitudinal direction. Unlike the glass run configured as described above, it is possible to avoid a situation in which a connecting line connecting adjacent molded bodies appears on the appearance. In addition, it is possible to avoid a situation in which a difference in color / gloss partially occurs in the longitudinal direction of the glass run 5. As a result, the appearance quality is improved.

  In the present embodiment, in the vicinity of the upper end portion of the front vertical side portion 7, the inner surface of the base portion 14 (vehicle outer base portion 14 a) is obliquely intersected with the sliding direction of the door glass G. An extended foreign material discharge guide groove 41 is formed. For this reason, even if foreign matter such as dust or mud that has entered the inside of the main body 11 is pushed up by the end surface of the rising door glass G, the foreign matter is formed in the vicinity of the upper end of the front vertical side portion 7. While entering the guide groove 41, the guide groove 41 excludes the side of the base portion 14 (vehicle outer base portion 14 a) facing the door glass G, that is, the position where it does not contact the door glass G. Accordingly, in the vicinity of the upper end portion of the front vertical side portion 7, it is possible to prevent a foreign matter from being deposited on a portion of the base portion 14 facing the end surface of the door glass G, and the door glass G is in sliding contact with the accumulated foreign matter. Thus, it is possible to prevent the occurrence of abnormal noise. In addition, it is possible to avoid a situation in which the door glass G gets on the foreign matter accumulated and causes a decrease in sealing performance and sound insulation performance.

  Furthermore, in the present embodiment, since the entire longitudinal direction of the glass run 5 is formed by molding, the guide groove 41 can be directly (integrally) formed in the base portion 14 during molding. Therefore, compared to a configuration in which a guide groove is provided by attaching another member to the inner side surface of the base portion 14, it is possible to improve manufacturing workability and reduce the weight and size of the glass run 5. Further, it is possible to avoid a situation in which another member projecting inward from the inner side surface of the base portion 14 is brought into pressure contact with the door glass G and the sliding property of the door glass G is lowered.

  In this embodiment, the guide groove 41 is formed only in the vicinity of the upper end portion of the front vertical side portion 7. For this reason, in a glass run in which the entire longitudinal direction is formed by molding, for example, compared with the case where the guide groove 41 is formed in the entire longitudinal direction of the front vertical side portion 7, the mold is simplified, and thus the mold is manufactured. Labor and cost can be reduced. In addition, compared with the case where the guide groove 41 is formed in the entire longitudinal direction of the front vertical side portion 7, when the door glass G is raised and lowered, the end surface of the door glass G is each of the base portion 14 (vehicle outer base portion 14a). It is possible to suppress a situation in which the sliding performance of the door glass G is reduced due to sliding contact with the portion between the guide grooves 41.

  Furthermore, the guide groove 41 extends in a direction that obliquely intersects the sliding direction of the door glass G. For this reason, for example, compared with the case where the guide groove 41 extends along the longitudinal direction of the front vertical side portion 7, the effect of scraping or scraping off the foreign matter pushed up by the end surface of the door glass G in the guide groove 41 is achieved. You can expect. In addition, since the guide groove 41 extends continuously in the thickness direction of the door glass G (in the lateral width direction of the vehicle exterior base portion 14a), the foreign matter pushed up on the end surface of the door glass G is further removed. It can be reliably excluded. Therefore, even when the guide groove 41 is provided only in the vicinity of the upper end portion of the front vertical side portion 7, the effect of preventing the accumulation of foreign matters at the upper end portion of the front vertical side portion 7 is reliably achieved.

  In addition, the guide groove 41 extends in a direction intersecting the sliding direction of the door glass G, so that the guide groove 41 extends along the longitudinal direction of the front vertical side portion 7. The moving distance of the foreign matter until the foreign matter that has entered the guide groove 41 is eliminated from the portion facing the end face of the door glass G to the position that does not contact the end face of the door glass G in the outer base portion 14a is shortened. be able to. Accordingly, the foreign matter can be removed relatively quickly from the portion of the vehicle outer base portion 14a facing the door glass G, and the foreign matter moves in the middle of the portion of the vehicle outer base portion 14a facing the door glass G. The risk of stagnation (such as mud solidification) can be suppressed.

  Further, since the guide groove 41 is inclined downward toward the vehicle outer side, foreign matter such as muddy water that has entered the guide groove 41 is guided to the vehicle outer side by the inclination of the guide groove 41. Accordingly, it is possible to more reliably prevent a situation in which a foreign object enters the indoor side.

  Further, three guide grooves 41 are provided in parallel to each other and at a predetermined distance in the sliding direction of the door glass G. For this reason, even when an assembly error of the door glass G, a molding error of the door glass G, or the like occurs, such an error can be absorbed, and the above-described effects are more reliably exhibited. Further, because the number of guide grooves 41 is excessively larger than necessary, the guide grooves 41 are formed in a relatively wide range in the sliding direction of the door glass G, or the distance between the guide grooves 41 becomes too short. Can be avoided. That is, when the guide groove 41 is formed in a relatively wide range in the sliding direction of the door glass G, the sliding contact amount with the door glass G at a predetermined portion between the guide grooves 41 is increased, and the sliding contact is made. There is a concern that abnormal noise is likely to occur due to the above. Further, even when the distance between the guide grooves 41 is narrow, the portion between the guide grooves 41 is more easily deformed in the sliding direction of the door glass G, and the portion between the door glass G and the guide groove 41 is in sliding contact. In such a case, there is a concern that abnormal noise is likely to occur. On the other hand, as in the present embodiment, each guide groove 41 is configured to have three guide grooves 41 and extend the plurality of guide grooves 41 so as to be parallel to each other so that foreign matter can be reliably guided. A plurality of guide grooves 41 can be formed so as to avoid the above-mentioned problems while ensuring the inner diameter of the guide.

  The front vertical side 7 is formed with a guide groove 42 that extends across the entire longitudinal direction of the front vertical side 7 along the boundary between the inner side surface of the vehicle outer base portion 14a and the side wall 15 of the vehicle outer side. The guide groove 41 is configured to communicate with the guide groove 42. For this reason, foreign matter such as muddy water guided to the side of the vehicle outer side base portion 14 a by the guide groove 41 can be guided to the lower end portion of the front vertical side portion 7 by the guide groove 42. Accordingly, the foreign matter can be discharged to the outside of the glass run 5 more reliably. Further, when the foreign matter removed from the portion facing the end surface of the door glass G of the vehicle exterior base portion 14a by the guide groove 41 to the side side of the vehicle exterior base portion 14a then moves downward, It is possible to suppress a situation in which the vehicle base portion 14a moves to the side opposite to the end surface of the door glass G and is pushed up again by the rising end surface of the door glass G.

  Furthermore, for example, when the guide groove 42 is formed in a glass run in which the end portions of the extrusion-molded portion are connected to each other by a mold-molded portion at a predetermined angle, the guide formed in the mold-molded portion is used. There is a concern that a step is formed at the boundary (joint) between the groove 42 and the guide groove 42 formed in the extrusion molding portion, and foreign matter may easily accumulate at the step. In contrast, as in the present embodiment, the entire length of the glass run 5 in the longitudinal direction is formed by molding, so that foreign matters can be discharged relatively smoothly through the guide groove 42.

  Further, by molding the glass run 5 in a shape in which the connecting portion 21 is extended, both the seal lips 12 and 13 can be sufficiently separated. For this reason, it is not necessary to set it as the expansion | deployment shape which the front-end | tip of the vehicle inner side wall part 16 and the vehicle outer side wall part 15 spread widely. Accordingly, when attaching to the sash portion DS and the channel portion DC, it is not necessary to greatly change the cross-sectional shape, so that the attachment state of the glass run 5 to the sash portion DS and the channel portion DC is stabilized, and the sealing property is improved. be able to.

  Further, the glass run 5 is integrally formed (the base portion 14, the vehicle interior side wall portion 16, the vehicle exterior side wall portion 15, the vehicle interior seal lip 13, the vehicle exterior seal lip 12, etc. are connected together via the connecting portion 21. Therefore, it is possible to simplify the entire manufacturing facility and improve manufacturing workability, and as a result, it is possible to reduce costs and improve productivity.

  The connecting portion 21 has a convex shape on the inner peripheral side of the main body portion 11. For this reason, for example, the connecting part 21 protrudes from the base part 14 of the front vertical side part 7 and the rear vertical side part 8 to the outer peripheral side of the door frame 2, so that the connecting part 21 becomes the sash part DS and the channel part. It is possible to suppress a situation in which the glass run 5 is lifted from the sash portion DS and the channel portion DC due to the repulsive force of the connecting portion 21 while being pressed against the DC (bottom surface). Therefore, by adopting this configuration, the glass run 5 can be suitably used even for an automobile having no space on the outer peripheral side of the door frame 2 at the portion of the sash portion DS where the vertical sides 7 and 8 of the glass run 5 are attached. Can be installed.

  Moreover, the connection part 21 is provided in the position (the vehicle inner side rather than the inner surface of the door glass G) remove | deviated from the opposing part of the end surface of the door glass G in the base part 14. FIG. For this reason, it is possible to prevent the possibility of causing problems such as an increase in resistance when the door glass G slides due to the connection portion 21 coming into contact with the door glass G. In addition, it is possible to avoid a situation in which the guide groove 41 is divided in the vehicle inside / outside direction by the connecting portion 21.

  Furthermore, the formation position of the connection part 21 in the vehicle interior / exterior direction is constant (on the same plane) in any part in the entire longitudinal direction of the glass run 5. For this reason, it becomes difficult to contract the connecting part 21 because the position of the connecting part 21 is displaced, or the cross-sectional shape of the connecting part 21 and thus the main body part 11 is deformed into an irregular shape by forcibly contracting (folding). The situation of doing can be suppressed. Therefore, it is possible to stabilize the mounting state, improve the mounting workability, improve the sealing performance, and the like.

  In addition, for example, when the connecting portion 21 is partially provided in the longitudinal direction of the glass run 5, the connecting portion 21 is contracted due to the thickness of the connecting portion 21 or the repulsive force of the connecting portion 21. As a result, the lateral width of the base portion 14 may change between the portion where the connecting portion 21 exists and the portion where the connecting portion 21 does not exist (the amount of contraction of the base portion 14 in the vehicle interior / exit direction may change). On the other hand, according to this embodiment, the connection part 21 is provided in the whole longitudinal direction of the glass run 5. For this reason, the lateral width of the base portion 14 can be made substantially uniform over the entire length of the glass run 5, and the attachment state can be stabilized.

  Further, in the glass run 5, the position of the root portion of the first variable portion 21 a and the position of the root portion of the second variable portion 21 b in the vehicle inside / outside direction are the same position in any part in the longitudinal direction of the glass run 5. Is molded as follows. For this reason, when the connecting portion 21 is contracted, the deformation amount of the connecting portion 21 can be made uniform, and the cross-sectional shape of the connecting portion 21 is partially deformed into an unintended shape in the longitudinal direction of the glass run 5. To prevent the first variable portion 21a and the second variable portion 21b from partially separating in the longitudinal direction of the glass run 5 or the connecting portion 21 from being uneven. it can.

  Furthermore, the first variable portion 21a and the second variable portion 21b are formed in a substantially linear shape, and along the boundary portion between the first variable portion 21a and the second variable portion 21b on the inferior angle side of the connecting portion 21. Thus, the groove-like portion 24 is formed, and the groove-like portion 24 makes the thickness near the boundary between the first variable portion 21a and the second variable portion 21b thinner than other portions. For this reason, by contracting (folding; making the cross-section substantially I-shaped) the connecting portion 21 having a substantially V-shaped cross section in the extended state, the front end portion side (the first variable portion 21a and the second variable portion). It is possible to prevent a situation in which the vicinity of the boundary with the part 21b swells. Accordingly, the connecting portion 21 comes into contact with the door glass G to reduce the sliding property of the door glass G, or the connecting portion 21 obstructs the operation of the vehicle interior seal lip 13 more reliably. Can be prevented.

  In addition, the first variable portion 21a and the second variable portion 21b respectively extend from the outer peripheral portion of the main body portion 11 of the surfaces of the vehicle outer base portion 14a and the vehicle inner base portion 14b that face each other. In the fixed state of the portion 21a and the second variable portion 21b (the contracted state of the connecting portion 21), the base side portions of the first variable portion 21a and the second variable portion 21b are the vehicle outer base portion 14a and the vehicle inner base. It is comprised so that it may be pinched | interposed into the part 14b. That is, the side surface of the base portion side of the first variable portion 21a and the second variable portion 21b comes into contact with the vehicle inner end surface of the vehicle outer base portion 14a and the vehicle outer end surface of the vehicle inner base portion 14b. For this reason, even when the connecting portion 21 is tilted when the connecting portion 21 is contracted, the side surfaces of the first variable portion 21a and the second variable portion 21b are in contact with the end surfaces of the vehicle outer base portion 14a and the vehicle inner base portion 14b. Tilt is prevented by touching. Therefore, the interference between the connecting portion 21 and the door glass G can be reliably prevented.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the guide groove 41 is formed on the inner surface of the base portion 14 in the vicinity of the upper end portion of the front vertical side portion 7. For example, instead of or in addition to the configuration, the rear vertical side portion Alternatively, a foreign matter discharge guide groove 41 may be formed on the inner side surface of the base portion 14 in the vicinity of the upper end portion 8.

  Moreover, in the said embodiment, although the guide groove 41 is parallel and mutually formed in three strips, the number of the guide grooves 41 is not specifically limited. However, even when an assembly error or manufacturing error of the door glass G and / or the glass run 5 occurs, the guide groove 41 is surely prevented from accumulating foreign matter near the upper end portion of the front vertical side portion 7. Is preferably 2 or more. Further, in order to avoid that the formation range of the guide grooves 41 in the sliding direction of the door glass G becomes too wide or the distance between the guide grooves 41 becomes too narrow, the guide grooves 41 should be 5 or less. It is desirable.

  In addition, the guide grooves 41 are not necessarily formed in parallel to each other, and may be provided side by side with a groove having a wide lower end side. Furthermore, in the said embodiment, although the guide groove 41 is comprised by the cross-sectional substantially semicircle shape, it is good also as, for example, being comprised by the cross-section substantially (reverse) triangular shape and the cross-section substantially U shape.

  (B) In FIG. 13 and the like showing the front vertical side portion 7, the foreign matter is discharged along the side portion on the vehicle exterior side of the vehicle exterior base portion 14 a (the boundary portion between the vehicle exterior base portion 14 a and the vehicle exterior side wall portion 15). The guide groove 42 is formed, and a groove-shaped portion is formed along the side portion on the vehicle inner side of the vehicle outer base portion 14a (the boundary portion between the vehicle outer base portion 14a and the connecting portion 21). However, the groove portion may be omitted. In this case, simplification of the mold, and consequently, labor and cost for manufacturing the mold can be reduced.

  (C) In the above embodiment, in the step after mold forming, the first variable portion 21a and the second variable portion 21b may be fixed in a state where they are in contact with each other on the surface. In this case, when the sash part DS and the channel part DC are attached, there is no need to maintain the contracted state of the connecting part 21 against the repulsive force of the connecting part 21, and the mounting workability can be improved. . In addition, since the first variable portion 21a and the second variable portion 21b are fixed to each other, when the glass run 5 is pushed into the sash portion DS and the channel portion DC, the portion on the vehicle inner side wall portion 16 side, etc. And the site | part by the side of the vehicle outer side wall part 15 can prevent the situation where it shift | deviates in the outer peripheral direction of the door glass G. Therefore, it is possible to improve the mounting workability, and it is possible to accurately attach the glass run 5 to the sash portion DS and the channel portion DC. Furthermore, there is a possibility that the connecting portion 21 swells as a hollow portion is formed inside the connecting portion 21, and the connecting portion 21 interferes with the door glass G to reduce the sliding property of the door glass G. Can be suppressed.

  Further, the entire surfaces of the first variable portion 21a and the second variable portion 21b facing each other may be fixed to each other. In this case, the first variable portion 21a and the second variable portion 21b are partially separated in a state where the connecting portion 21 having a substantially V-shaped cross section is contracted (folded; formed in a substantially I-shaped cross section). Therefore, it is possible to prevent a situation in which the connecting portion 21 is swollen (a hollow portion is formed). Therefore, the connecting portion 21 interferes with the door glass G, so that the sliding performance of the door glass G is reduced, or the connecting portion 21 obstructs the operation of the vehicle interior seal lip 13 more reliably. Can be prevented. Furthermore, the first variable portion 21a and the second variable portion 21b may be bonded to each other in the entire longitudinal direction of the glass run 5. The first variable portion 21a and the second variable portion 21b only need to be fixed (adhered) to each other at least at a predetermined interval, but it is more preferable to be fixed in the entire longitudinal direction of the glass run 5. Examples of the fixing method include adhesion using an adhesive, thermal welding, ultrasonic welding, and the like.

  (D) Moreover, in the said embodiment, although the glass run 5 is comprised by TPV, other things, such as ethylene-propylene-diene copolymer rubber (EPDM) and a non-crosslinked type olefin type thermoplastic elastomer (TPO), are different. You may comprise by the material of. In addition, by comprising the glass run 5 by TPV, it becomes possible to heat-weld or ultrasonically weld the 1st variable part 21a and the 2nd variable part 21b. Further, by adopting an olefin-based thermoplastic elastomer having a viscosity lower than that of EPDM as a constituent material of the glass run 5, it becomes easy to spread the constituent material of the glass run 5 to every corner of the mold cavity. There are effects such as suppressing the complexity of the structure.

  (E) In the above embodiment, the first variable portion 21a and the second variable portion 21b extend from the surfaces of the vehicle outer base portion 14a and the vehicle inner base portion 14b that face each other. The first variable portion 21a and the second variable portion 21b may be configured to extend from the side end portions of the inner side surfaces (the inner peripheral surface of the main body portion 11) of the vehicle outer base portion 14a and the vehicle inner base portion 14b. Good.

  (F) The build-up portions 32a, 32b, 32c, and 32d for adjusting the inclination of the door glass G when the window portion W is closed can be appropriately changed for each vehicle type. For example, the portions shown in FIGS. It is also possible to omit the built-up portions 32b and 32c. Further, the sub lip 31 provided in the part disposed below the belt line of the rear vertical side part 8 or the front vertical side part 7 does not need to be provided in the entire longitudinal direction of the part, for example, FIG. It is also possible to omit the sub lip 31 at the site shown in FIG.

  (G) In the above embodiment, the glass run 5 for the front door has been described in detail, but it may be applied to a glass run for a rear door or the like.
