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 each extending toward the inside of the main body portion are provided. 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.

  In addition, the mold forming part corresponding to the corner part of the glass run needs to contain a mold (core) for forming each inner surface of the main body part, the vehicle interior seal lip, and the vehicle exterior seal lip at the time of mold forming. In general, in order to maintain the holding strength of the core, the inner side wall portion and the outer side wall portion of the vehicle are generally formed in an unfolded shape. However, when the vehicle interior side wall portion and the vehicle exterior side wall portion are deformed so as to be narrowed at the time of attachment to the attachment portion, the bending angle (curvature radius), circumference, etc. of the corner portion are based on the stress at that time. May change. In this case, the glass run may not follow the shape of the attachment portion, which may cause deterioration of the attachment state.

  On the other hand, as shown in FIG. 6, a connecting portion 74 that can be expanded and contracted in the inside and outside of the vehicle is provided in the base portion 73, and the entire lengthwise direction is integrally formed by molding so that the connecting portion 74 extends. At the same time, a glass run 71 is proposed in which the connecting portion 74 is shrunk when attached to the attaching portion 70 (see, for example, Patent Document 1).

JP 2008-149739

  By adopting the technique of Patent Document 1, it is possible to avoid a situation in which a difference in color / gloss partially occurs in the longitudinal direction of the glass run, or that the glass run needs to be developed.

  By the way, as shown in FIG. 6, the connection part 74 may be provided in the position which does not contact with the door glass G (in FIG. 6, rather than the door glass G) so that sliding of the door glass G may not be prevented. Conceivable. However, when the window portion of the door is closed and the base portion 73 of the upper side portion 71a of the glass run 71 is pressed and deformed by the upper edge portion of the rising door glass G, the connection portion 74 is attached along with the deformation. There is a concern that the root portion side is displaced upward and the tip portion side is inclined toward the door glass G side (the vehicle outer side) and is in pressure contact with the back surface of the vehicle inner seal lip 75. As a result, the inside seal lip 75 is sandwiched between the connecting portion 74 and the door glass G, and when the door glass G further rises from this state, the inside seal lip 75 is connected as shown by the two-dot chain line in FIG. There is a risk that the part 74 and the door glass G may be lifted relatively large upward. Further, the vehicle interior side wall 76 is pulled by the vehicle interior seal lip 75 and tilts to the vehicle exterior side, and the front end portion of the vehicle interior side wall 76 and the vehicle interior design lip 77 are lifted from the mounting portion 70 (the mounting portion). 70), and there is a possibility that the appearance quality and the sealing performance may be deteriorated.

  The present invention has been made in view of the above circumstances, and its purpose is to improve the appearance quality and the like, and suppress the deterioration of the appearance quality and the sealing performance when the door window is closed. To provide a run.

  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. The vehicle 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 has a substantially U-shaped cross section provided along the inner periphery of the door frame of the vehicle. A main body part to be attached to the mounting part formed;
A vehicle inner side seal lip and a vehicle outer side seal lip extending inward of the main body from substantially the front ends of the vehicle inner side wall and the vehicle outer side wall,
The base portion is provided with a connecting portion formed in a substantially V-shaped cross section that protrudes toward the inner peripheral side of the main body portion at the time of molding at a position deviating from the facing portion of the end face of the door glass in the base portion. ,
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 part is a glass run formed continuously throughout the longitudinal direction of the main body part,
The base portion of the upper side portion protrudes from the outer surface of the base portion at a portion closer to the connecting portion than the portion facing the end surface of the door glass, and hits the mounting portion in the attached state to the mounting portion. A glass run provided with a contact rib in contact with or close to.

  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.

  Furthermore, both the sealing lips can be sufficiently separated by molding the glass run in a shape in which the connecting portion is extended. For this reason, in order to maintain the holding strength of the mold (core) for molding the inner side surface of the main body, etc., it is necessary to have a deployed shape in which the tips of the vehicle inner side wall portion and the vehicle outer side wall portion are greatly expanded. Disappears. Accordingly, since it is not necessary to greatly change the cross-sectional shape when attaching to the attachment portion, it is possible to stabilize the attachment state of the glass run to the attachment portion, improve the sealing performance, and the like.

  Further, in this means, the base portion of the upper side portion protrudes from the outer surface of the base portion at a portion closer to the connection portion than the portion facing the end surface of the door glass, and hits the attachment portion in the attached state to the attachment portion. Contact ribs that are in contact with or close to each other are provided. Thereby, when closing the window part of the door, even if the upper edge part of the rising door glass is pressed against the base part of the upper side part of the glass run and the base part deforms following, the connecting part of the base part As for the connecting part, the deformation is suppressed (upward) by the abutment rib coming into contact with the mounting portion and stretching. For this reason, with the deformation of the base part, the base part side of the connecting part is displaced upward, the tip part side tilts to the door glass side, presses against the seal lip, and is sandwiched between the door glass and the connecting part However, it is possible to prevent such a situation that it is lifted upward by being caught between the rising door glass and the connecting portion. Therefore, the side wall portion is pulled by the seal lip and tilted toward the door glass, and the front end portion of the side wall portion (the design lip when the design lip is provided at the substantially front end of the side wall portion) is lifted from the mounting portion (sash (A gap is formed between the two parts) can be avoided, and as a result, it is possible to prevent deterioration in appearance quality and sealing performance.

  Further, the abutment rib is provided at a position out of the base portion away from the portion facing the end surface of the door glass. For this reason, while the door glass comes into contact with the base portion of the upper side portion and the base portion comes into contact with the mounting portion and the rise of the door glass is stopped, the base portion is bent, Can absorb shocks. Accordingly, for example, the abutment rib is provided corresponding to the portion of the base portion that faces the end surface of the door glass, and the door glass is stopped from moving up almost simultaneously with the door glass contacting the base portion of the upper side ( Compared with a configuration in which the base portion hardly bends), it is possible to suppress the collision noise of the door glass when the window portion is closed.

  In addition, since the glass run is integrally formed (the base, the vehicle inner side wall, the vehicle outer side wall, the vehicle inner seal lip, the vehicle outer seal lip, etc. are formed in a continuous manner through the connecting portion), It is possible to simplify the entire manufacturing facility and improve manufacturing workability. As a result, it is possible to reduce costs and improve productivity. In particular, since the connecting portion is formed in the entire longitudinal direction of the glass run, for example, compared to the configuration described in JP 2008-149739 in which the connecting portion is partially provided in the longitudinal direction of the glass run. When filling the mold cavity with the constituent material, the constituent material is easily spread over the entire cavity. For this reason, improvement of manufacturing workability (shortening of manufacturing time), suppression of molding defects, simplification of a mold apparatus, and the like can be achieved.

  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. Due to the contact of the part with the door glass, it is possible to prevent the possibility of incurring problems such as an increase in resistance when the door glass slides. Also, since the connecting part is convex on the inner peripheral side of the main body part, for example, the connecting part is attached due to the connecting part protruding from the base part of the vertical side part to the outer peripheral side of the door frame. It is possible to suppress a situation in which the glass run is lifted from the attachment portion due to the repulsive force of the connecting portion due to pressure contact with the portion or the like.

  In addition, in the state where the glass run is attached to the attachment part, even when the door glass is not in pressure contact with the base part of the upper side part, the structure in which the abutment rib is “pressure contact” or “contact” with the attachment part is adopted. In this case, it is possible to expect an effect such as suppressing the tilt of the connecting portion toward the door glass (in the case of press contact, particularly bringing the connecting portion toward the side wall). In this case, it is possible to more reliably prevent a situation in which the sliding property of the door glass is lowered due to the connection portion coming into contact with the door glass or the seal lip.

Mean 2. The connecting part is composed of a first variable part located near the opposite part of the end face of the door glass in the base part, and a second variable part located far away,
2. The glass run according to claim 1, wherein the abutment rib exists on an extension line of the first variable portion at least in a state where the main body portion is attached to the attachment portion.

  According to the means 2, the abutment rib is provided so as to exist on the extension line of the first variable portion. For this reason, when the base part of the upper side is pressed and deformed by the door glass, the first variable part and the second variable part are likely to be relatively displaced in the sliding direction of the door glass. Such a situation can be suppressed. Therefore, the connection part swells as if a hollow part is formed inside the connection part, and the connection part is brought into contact with the door glass or the seal lip, thereby suppressing the risk of reducing the sliding property of the door glass. be able to.

  Further, by providing the abutment rib so as to exist on the extension line of the first variable portion, it is possible to separate the rib as much as possible from a portion of the base portion facing the end surface of the door glass. In this case, the effect of absorbing the impact of the door glass when the window portion is closed by the base portion is more reliably achieved.

  Means 3. The connecting portion is composed of a first variable portion located near the opposite portion of the end face of the door glass in the base portion, and a second variable portion located far away, and the first variable portion and the second variable portion. The glass run according to means 1 or 2, characterized in that the variable part is fixed in a state of being in contact with each other on the surface.

  According to the means 3, since the first variable portion and the second variable portion constituting the connecting portion are fixed to each other, the connecting portion is contracted against the repulsive force of the connecting portion when attached to the attaching portion. It is not necessary to maintain the position, and the mounting workability can be improved. In addition, since the first variable portion and the second variable portion are fixed to each other, when the glass run is pushed into the mounting portion, the portion on the vehicle inner side wall portion side and the vehicle outer side wall portion side of the glass run It is possible to prevent a situation in which the portion is displaced in the outer peripheral direction of the door frame. Accordingly, it is possible to improve the mounting workability and to attach the glass run to the mounting portion accurately.

  In addition, it is possible to suppress the risk that the connecting portion swells so that a hollow portion is formed inside the connecting portion, and the connecting portion comes into contact with the door glass or the seal lip to reduce the sliding property of the door glass. be able to. Examples of the fixing method include adhesion using an adhesive, and thermal welding, ultrasonic welding, and the like when the glass run is composed of a dynamically crosslinked olefin-based thermoplastic elastomer (TPV).

  Further, when the abutment rib is provided so as to exist on the extension line of the first variable portion as in the above-described means 2, the first variable portion and the first variable portion when the base portion is deformed when the window portion is closed. It is possible to prevent such a situation that the two variable parts are relatively displaced in the sliding direction of the door glass. For this reason, the situation where the 1st variable part will peel from the 2nd variable part can be controlled. Therefore, the situation where a hollow part will be formed inside a connection part can be prevented more reliably.

  Means 4. The connecting portion is provided on the vehicle interior side of the base portion than the facing portion of the end surface of the door glass, and the abutment rib is provided only on the vehicle inner side than the portion of the base portion facing the end surface of the door glass. The glass run according to any one of means 1 to 3, characterized in that:

  Of the base portion, the portion between the facing portion of the door glass and the contact rib, and the portion connected to the contact rib, the contact rib stretches even if the base portion is bent upward. Therefore, it will incline diagonally. For this reason, if the distance between the facing portion of the base portion facing the end surface of the door glass and the abutment rib is too close, the door glass may be shifted and moved in and out of the vehicle so as to be guided by the inclined base portion. . Therefore, for example, when the abutting rib is provided on the vehicle outer side than the portion facing the end surface of the base door glass, and the distance between the facing portion of the base door glass end surface and the abutting rib is short, the door glass is There is a concern that it will be guided to the base and displaced toward the inside of the vehicle. In this case, there is a risk that the door glass that has been required in the field of automobiles and the like in recent years may be hindered. It should be noted that the distance between the base portion facing the end face of the door glass and the abutment rib is close when there is not enough space to separate them, or when there is a door glass assembly error or molding error. It is possible to do.

  On the other hand, in this means 4, since the contact rib is provided only on the vehicle interior side than the portion facing the end surface of the base portion door glass, the portion facing the end surface of the base portion door glass and the contact rib Even if they are close to each other, the door glass is guided to the base portion and displaced to the outside of the vehicle. Accordingly, it is possible to avoid a situation in which the door glass is hindered from being flash surfaced.

  In many cases, the glass run has a larger inside seal lip than the outside seal lip in order to achieve a flash surface. Thus, the vehicle enters a position closer to the vehicle outer side than the center portion in the width direction of the base portion. That is, a relatively large space can be secured on the vehicle interior side than the portion of the base portion facing the end surface of the door glass, and the connecting portion can be provided without difficulty using the space so as not to contact the door glass. Can do. In addition, even if the contact rib is provided at the connection portion of the base portion with the connecting portion, the contact portion of the base portion facing the end surface of the door glass and the contact rib can be separated as much as possible. Therefore, it is possible to reliably absorb the impact at the time of the collision of the door glass by the base portion while suppressing the situation that the door glass is displaced in the vehicle interior / exterior direction by the base portion.

It is the JJ sectional view taken on the line of FIG. 2 which shows the glass run after attachment. It is the JJ sectional view taken on the line of FIG. 2 which shows the glass run immediately after mold forming. It is sectional drawing which shows the glass run at the time of window part closing. It is sectional drawing which shows the conventional glass run.

  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 this embodiment, the glass run 5 is comprised by the dynamic bridge | crosslinking type olefin type thermoplastic elastomer (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 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, and has a substantially U-shaped cross section. From the main body part 11 fitted into the character-shaped sash part DS, the vehicle outer side seal lip 12 extending from the front end part of the vehicle outer side wall part 15 toward the vehicle inner side and the base part 14 side, and the front end part of the vehicle inner side wall part 16 A vehicle inner side seal lip 13 extending toward the vehicle outer side and the base portion 14 side is provided. 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. Note that the vehicle outer side wall portion 15 and the vehicle inner side wall portion 16 on the vehicle inner surface protrude outward from the main body portion 11 and are hooked on a stepped portion formed on the inner peripheral side of the sash portion DS. Stop ribs 15a and 16a are formed, and thereby, the upper side portion 6 is prevented from coming off from the sash portion DS.

  The upper side portion 6 includes an exterior design lip 17 extending from the distal end portion of the vehicle outer side wall portion 15 toward the vehicle exterior side, and an interior design lip 18 extending from the distal end portion of the vehicle interior side wall portion 16 toward the vehicle interior side. It has. The vehicle exterior design lip 17 and the vehicle interior design lip 18 of the upper side portion 6 have such a size that the edge of the sash portion DS can be hidden. In addition, a draining lip 19 that protrudes from the base portion 14 is provided on a vehicle outer side portion of the outer side surface of the base portion 14 (the outer peripheral surface 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. In addition, the extension length from the base part 14 of the vehicle outer side wall part 15 is shorter than the extension length from the base part 14 of the vehicle inner side wall part 16. The vehicle exterior seal lip 12 is configured to be smaller (shorter and thinner) 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.

  Now, the base part 14 is provided with a connecting part 21 formed so that the lateral width of the base part 14 can be changed between when the mold is molded and when the base part 14 is attached to the sash part DS (channel part DC). Yes. The base portion 14 of the present embodiment is divided into a vehicle outer side portion (vehicle outer side base portion 14a) and a vehicle inner side portion (vehicle inner side base portion 14b) with the connecting portion 21 interposed therebetween. The portion 14 a and the vehicle interior base portion 14 b are connected by the connecting portion 21. The connecting portion 21 includes a first variable portion 21a extending from the vehicle inner end surface of the vehicle outer base portion 14a to the inner peripheral side of the main body portion 11, and a tip end of the first variable portion 21a from the vehicle outer end surface of the vehicle inner base portion 14b. And a second variable portion 21b extending toward the edge. Further, as shown in FIG. 4, the connecting portion 21 is formed in a substantially V-shaped cross section that protrudes toward the inner peripheral side of the main body portion 11, and the sash portion DS (channel portion) of the glass run 5 at the time of molding. At the time of attachment to DC), as shown in FIG. 3, the connecting portion 21 is contracted (folded) and attached in that state. 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). The connecting portion 21 is configured not to contact 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. .

  In this embodiment, the connecting portion 21 has an elongated shape with a substantially V-shaped cross section, and the glass run 5 including the main body portion 11, the seal lips 12, 13 and the like is integrally molded. The first variable portion 21a and the second variable portion 21b are bonded to each other with an adhesive in a state where the first variable portion 21a and the second variable portion 21b are in contact with each other. That is, at the time of molding, the connecting portion 21 is extended and the vehicle outer base portion 14a and the vehicle inner base portion 14b are separated from each other. In the subsequent steps, the first variable portion 21a and the second variable portion 21b are formed. Are fixed to each other, the contracted state of the connecting portion 21 is maintained, and a shape that can be directly inserted into the sash portion DS is obtained. In the present embodiment, the adhesive is applied to the entire surfaces of the first variable portion 21a and the second variable portion 21b that face each other, and the entire surfaces of the first variable portion 21a and the second variable portion 21b that face each other. It is glued.

  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. For this reason, as shown in FIG. 3, even when the connecting portion 21 is in a contracted state, the distal end portion of the connecting portion 21 (near the boundary portion between the first variable portion 21a and the second variable portion 21b) does not swell, 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, although illustration is abbreviate | omitted, the front vertical side part 7 and the rear vertical side part 8 of the glass run 5 are also provided with the main-body part 11, a pair of seal lips 12, 13 and the connection part 21 grade | etc., Similarly to the upper side part 6. ing. Moreover, the connection part 21 formed in the upper side part 6, the front vertical side part 7, and the rear vertical side part 8 is unbroken throughout the longitudinal direction of the glass run 5 like the main body part 11 and the seal lips 12, 13 and the like. The first variable portion 21a and the second variable portion 21b are bonded to each other over the entire length of the glass run 5 in a longitudinal direction. Furthermore, the formation position of the connecting portion 21 in the vehicle interior / exterior direction is unified at the same position throughout the longitudinal direction of the glass run 5 (same at any position in the longitudinal direction), and the base portion 14 The width is also the same.

  Now, in the present embodiment, the outer surface of the base portion 14 (opposite the bottom surface of the sash portion DS on the outer peripheral side of the door frame 2) at the connecting portion between the vehicle outer base portion 14a and the first variable portion 21a of the upper side portion 6. The abutting rib 31 is provided so as to protrude from the upper surface (upper left in FIG. 3). The abutment rib 31 exists on the extension line of the first variable portion 21 a at least in the contracted state of the connecting portion 21, and is located on the vehicle inner side than the vehicle inner side surface of the door glass G. In the present embodiment, when the connecting portion 21 is in the contracted state, the inner surface of the abutment rib 31 is substantially flush with the inner surface of the first variable portion 21a (the surface facing the second variable portion 21b). The outer base portion of the rib 31 at a position where the outer surface of the rib 31 is on the outer side of the first connecting portion 21a and at a predetermined distance from the facing portion of the outer base portion 14a to the end surface of the door glass G. It is connected to the outer surface of 14a. The abutment rib 31 has a substantially trapezoidal cross section, and is formed directly (integrally) on the base portion 14 simultaneously with other portions when the glass run 5 is molded. And the upper side part 6 is attached to the sash part DS, and the front end surface of the contact rib 31 contacts the bottom face of the sash part DS.

  In addition, the contact rib 31 is not formed in the vehicle outer side base part 14a in the site | part of the vehicle outer side rather than the door glass G, but the draining lip 19 is formed as mentioned above. The draining lip 19 extends obliquely from the outer surface of the vehicle outer base portion 14a toward the vehicle outer side, and contacts the sash portion DS when the glass run 5 is attached to the sash portion DS, and is deformed to be bent. On the other hand, the abutting rib 31 does not deform so much even if it abuts against the sash portion DS, and the cross-sectional shape is substantially maintained. Further, the vehicle exterior base portion 14a located between the abutment rib 31 and the draining lip 19 is also from the bottom surface of the sash portion DS (about the protruding length of the abutment rib 31) even when the upper side portion 6 is attached to the sash portion DS. ) Separated.

  Further, as described above, in the present embodiment, the first variable portion 21a of the connecting portion 21 is the surface of the main body portion 11 on the surface (the vehicle inner surface) that faces the vehicle inner base portion 14b of the vehicle outer base portion 14a. It extends from the outer peripheral part. Thereby, the groove part 41 is formed in the boundary part of the 1st variable part 21a and the vehicle outer side base part 14a (the inner surface).

  Next, the deformation | transformation operation | movement of the glass run 5 at the time of closing the window part W is demonstrated. As shown in FIG. 5, when the door glass G rising to close the window portion W enters the inside of the main body portion 11 of the upper side portion 6, the seal lips 12 and 13 are deformed so as to be spread, and the door The end face of the glass G comes into contact with the base portion 14 (vehicle outer base portion 14a), and the vehicle outer base portion 14a is pressed by the door glass G to bend and deform in a follow-up manner. At this time, the vehicle exterior base portion 14a is lifted up to abut against the bottom surface of the sash portion DS with the portion facing the end surface of the door glass G as the center, but the connection portion 21 is in contact with the bottom surface of the sash portion DS. Deformation in which the first variable portion 21a is displaced upward is suppressed by stretching the contacting rib 31 in contact therewith. That is, a situation in which the connecting portion 21 is inclined to the outside of the vehicle due to the displacement of the root portion of the first variable portion 21a upward (the bottom surface side of the sash portion SD) is suppressed.

  In addition, in the exterior base part 14a, the part between the part facing the end surface of the door glass G and the contact rib 31 and the part connected to the contact rib 31, the exterior base part 14a is Even if it bends upward, the abutment rib 31 is stretched, so that it is inclined obliquely. For this reason, when the distance between the facing portion of the vehicle exterior base portion 14a and the end surface of the door glass G and the contact rib 31 is too close, the vehicle exterior direction is such that the door glass G is guided to the tilted vehicle exterior base portion 14a. It is conceivable to shift to On the other hand, in the present embodiment, when the vehicle outer base portion 14a is deformed by being pressed by the door glass G, the portion of the vehicle outer base portion 14a that faces the end surface of the door glass G contacts the bottom surface of the sash portion DS. The part facing the end surface of the door glass G of the vehicle exterior base portion 14a and the contact rib 31 are sufficiently separated so as to contact each other. In other words, of the vehicle exterior base portion 14a, the point where the door glass G first contacts the vehicle exterior base portion 14a of the upper side portion 6 (for example, the central portion in the thickness direction) extends in the sliding direction of the door glass G. The distance between the portion located at the position and the abutment rib 31 is configured to be longer than the protruding length of the abutment rib 31 from the vehicle exterior base portion 14a. Accordingly, it is possible to prevent the door glass G from being displaced inward and outward by the vehicle outer base portion 14a, and when the door glass G collides with the vehicle outer base portion 14a, The portion between the portion facing the end surface of the door glass G and the abutment rib 31 is deformed following, so that the impact when the door glass G collides can be reliably absorbed. Moreover, in this embodiment, since the abutment rib 31 is provided in the vehicle inner side rather than the site | part facing the end surface of the door glass G of the vehicle exterior base part 14a, the door glass G, the glass run 5, and the sash part DS are provided. Even if a manufacturing error, an assembly error of the door glass G, or the like occurs and the distance between the facing portion 31 of the vehicle exterior base portion 14a and the end face of the door glass G and the abutment rib 31 is short, the door glass G is guided to the vehicle outer base 14a and displaced to the vehicle outer side. Therefore, for example, it is possible to avoid a situation in which the door glass G is guided to the vehicle inner side by the vehicle outer side base portion 14a and the flash surface formation of the door glass G is hindered.

  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.

  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, in the present embodiment, the base portion 14 of the upper side portion 6 protrudes from the outer surface of the base portion 14 at the connecting portion between the vehicle outer side base portion 14a and the first variable portion 21a, and the sash portion DS of the upper side portion 6 is. An abutment rib 31 that abuts against the bottom surface of the sash portion DS in the attached state is provided. Thereby, when closing the window part W of the door 1, when the upper edge part of the rising door glass G press-contacts with the vehicle outer side base part 14a of the upper side part 6, and the vehicle outer side base part 14a deform | transforms in a tracking manner However, regarding the connection part with the connection part 21 (1st variable part 21a) among the vehicle outer side base parts 14a, the deformation | transformation to upper direction is suppressed because the abutment rib 31 contact | abuts and stretches against the sash part DS. Become. For this reason, along with the deformation of the vehicle exterior base portion 14a, the base portion side of the connecting portion 21 is displaced upward and the tip end portion is tilted toward the door glass G side so as to come into pressure contact with the vehicle interior seal lip 13, and the door glass G It is possible to prevent the vehicle interior seal lip 13 sandwiched between the connecting portions 21 from being lifted upward so as to be caught between the rising door glass G and the connecting portion 21. Accordingly, the vehicle interior side wall portion 16 is pulled by the vehicle interior seal lip 13 and tilts toward the door glass G, and the front end portion of the vehicle interior side wall portion 16 and the vehicle interior design lip 18 are lifted from the sash portion DS (sash portion). A situation in which a gap is formed with the DS) can be avoided, and as a result, it is possible to prevent deterioration in appearance quality and sealing performance.

  Further, the abutment rib 31 is provided at a position away from a portion facing the end surface of the door glass G in the base portion 14 (vehicle outer base portion 14a). For this reason, after the door glass G comes into contact with the vehicle outer base portion 14a of the upper side portion 6, the vehicle outer base portion 14a and the bottom surface of the sash portion DS come into contact with each other until the rise of the door glass G is stopped. In the meantime, the impact of the door glass G can be absorbed while the vehicle exterior base portion 14a is bent. Accordingly, for example, the abutment rib 31 is provided corresponding to a portion of the vehicle outer base portion 14a that faces the end surface of the door glass G, and the door glass G substantially contacts the vehicle outer base portion 14a of the upper side portion 6. At the same time, the collision noise of the door glass G when the window W is closed can be suppressed as compared with the configuration in which the raising operation of the door glass G is stopped (the vehicle outer base portion 14a hardly bends).

  In addition, for example, it can be considered that the vehicle interior seal lip 13 is shortened so that the connection portion 21 and the vehicle interior seal lip 13 do not contact even if the connection portion 21 is tilted. In the sliding direction of the door glass G, the contact position of the vehicle interior seal lip 13 with the door glass G and the contact position of the vehicle exterior seal lip 12 with the door glass G are relatively separated from each other. There is a risk of inconveniences such as easy rattling and reduced sealing performance. On the other hand, it is conceivable to shorten the variable portions 21a and 21b of the connecting portion 21, but in this case, molding may be difficult or practically impossible. On the other hand, by adopting a configuration that prevents the connecting portion 21 and the inboard seal lip 13 from being pressed by preventing the connecting portion 21 from being tilted as in the present embodiment, the window can be avoided while avoiding the above problems. It is possible to prevent the appearance quality and the sealing performance from being lowered when the portion W is closed.

  The abutment rib 31 is provided so as to exist on the extension line of the first variable portion 21a. For this reason, when the vehicle outer side base part 14a of the upper side part 6 is pressed and deform | transformed by the door glass G, the 1st variable part 21a and the 2nd variable part 21b are relatively in the sliding direction of the door glass G. It is possible to suppress a situation in which misalignment is likely to occur. Accordingly, the connecting portion 21 swells so that a hollow portion is formed inside the connecting portion 21, and the connecting portion 21 comes into contact with the door glass G and the vehicle interior seal lip 13, thereby reducing the sliding property of the door glass G. It is possible to suppress the risk of causing it to occur.

  Furthermore, by providing the abutment rib 31 so as to exist on the extension line of the first variable portion 21a, it is possible to separate the rib 31 as much as possible from a portion facing the end surface of the door glass G of the vehicle exterior base portion 14a. . In this case, the effect of absorbing the impact of the door glass G when the window portion W is completely closed is absorbed by the vehicle exterior base portion 14a.

  In addition, in the present embodiment, when the glass run 5 is attached to the sash portion DS and the door glass G is not in pressure contact with the vehicle exterior base portion 14a of the upper side portion 6, the abutment rib 31 has the sash portion DS. It is in contact with the bottom surface. For this reason, the effect of suppressing tilting of the connecting portion 21 toward the vehicle outer side (door glass G side) is expected (particularly, the connecting portion 21 is brought closer to the vehicle inner side wall portion 16 when pressed). You can also In this case, it is possible to more reliably prevent a situation in which the sliding property of the door glass G is lowered due to the connection portion 21 coming into contact with the door glass G or the vehicle interior seal lip 13.

  Further, the connecting portion 21 is fixed in a state where the first variable portion 21a and the second variable portion 21b are in contact with each other on the surface in the process after the molding. For this reason, when attaching to the sash part DS and the channel part DC, it is not necessary to maintain the contracted state of the connecting part 21 against the repulsive force of the connecting part 21 and to improve the mounting workability. it can. 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. It is possible to prevent a situation in which the portion on the vehicle outer side wall portion 15 side is shifted in the outer peripheral direction of the door frame 2. 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 risk that the connecting portion 21 swells as a hollow portion is formed inside the connecting portion 21, and the connecting portion 21 comes into contact with the door glass G to reduce the sliding property of the door glass G. Can be suppressed. In addition, as described above, the abutment rib 31 is provided so as to exist on the extension line of the first variable portion 21a, so that the first variable when the vehicle outer base portion 14a is deformed when the window portion W is closed. It is possible to prevent a situation in which the portion 21a and the second variable portion 21b are relatively displaced in the sliding direction of the door glass G. For this reason, the situation where the 1st variable part 21a peels from the 2nd variable part 21b can be suppressed. Therefore, the situation where a hollow part will be formed inside the connection part 21 can be prevented more reliably.

  In the present embodiment, a groove 41 is formed at the boundary between the first variable portion 21a and the inner side surface of the vehicle exterior base portion 14a. For this reason, when the vehicle inner side edge of the inner surface of the vehicle outer base portion 14a is pulled to the vehicle outer side by pressing the vehicle outer base portion 14a against the door glass G, the groove portion 41 is opened (the vehicle outer side). The base portion 14a is deformed so that the inner surface of the base portion 14a is inclined outward. Therefore, the situation that the stress accompanying the deformation of the vehicle exterior base portion 14a acts on the coupling portion 21 (first variable portion 21a) can be suppressed, and the vehicle exterior side (door glass G side) of the coupling portion 21 can be suppressed. Can be reliably prevented.

  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. In particular, since the connecting portion 21 is formed in the entire longitudinal direction of the glass run 5, for example, compared to a configuration in which the connecting portion 21 is partially provided in the longitudinal direction of the glass run 5, When filling the constituent material, it is easy to spread the constituent material over the entire cavity. For this reason, improvement of manufacturing workability (shortening of manufacturing time), suppression of molding defects, simplification of a mold apparatus, and the like can be achieved.

  In addition, 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.

  Furthermore, the formation position of the connecting portion 21 in the vehicle interior / exterior direction is constant 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) the substantially V-shaped connecting portion 21, the tip end side of the connecting portion 21 (near the boundary between the first variable portion 21a and the second variable portion 21b) swells. The situation can be prevented. 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 portion of the first variable portion 21a and the second variable portion 21b and 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 are in contact with or close to each other. It becomes. 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 contact 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-described embodiment, the abutment rib 31 is provided so as to exist on the extended line of the first variable portion 21a at least in the contracted state of the connecting portion 21, but for example, the vehicle exterior side than the first variable portion 21a. And it is good also as providing the contact rib 31 in the site | part inside a vehicle rather than the door glass G (facing part with the end surface of the door glass G of the vehicle outer side base part 14a). Also in this case, it is possible to suppress a situation in which the connecting portion 21 is inclined to the vehicle outer side due to the base portion 14 (the vehicle outer side base portion 14a) being pressed and deformed by the door glass G. However, it is possible to avoid problems caused by the contact rib 31 being close to the portion facing the end surface of the door glass G of the vehicle exterior base portion 14a, or the relative relationship between the first variable portion 21a and the second variable portion 21b. From the standpoint of preventing misalignment, it is desirable that the abutment rib 31 be provided so as to exist on the extension line of the first variable portion 21a in the contracted state of the connecting portion 21.

  (B) In the above embodiment, the first variable portion 21a and the second variable portion 21b are bonded with an adhesive, but the first variable portion 21a and the second variable portion 21b are thermally welded or ultrasonically welded. It may be adhered by, for example. The first variable portion 21a and the second variable portion 21b are fixed (adhered) to each other at a predetermined interval, or the first variable portion 21a and the second variable portion 21b are not bonded (adhered). However, from the viewpoint of mounting workability and stability of the cross-sectional shape, it is possible to employ a configuration in which the first variable portion 21a and the second variable portion 21b are fixed in the entire longitudinal direction of the glass run 5. Is more preferable.

  Moreover, in the said embodiment, although the glass run 5 is comprised by TPV, by another raw materials, such as ethylene-propylene-diene copolymer rubber (EPDM) and a non-crosslinked olefin type thermoplastic elastomer (TPO), it is. It may be configured. 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.

  (C) In the embodiment described above, the first variable portion 21a and the second variable portion 21b extend from the mutually facing surfaces of the vehicle outer base portion 14a and the vehicle inner base portion 14b. 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. Even in the case of adopting this configuration, the groove portion 41 is provided at the boundary between the first variable portion 21a and the inner side surface of the vehicle outer base portion 14a (the connecting portion of the vehicle outer base portion 14a with the first variable portion 21a). It is good also as forming. In this case, it is possible to suppress a situation in which the stress associated with the deformation of the vehicle outer base portion 14a acts on the connecting portion 21 (first variable portion 21a), and the vehicle outer side (door glass G side) of the connecting portion 21. It is possible to prevent the tilting to a more reliably.

  (D) 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. Moreover, you may apply to the glass run 5 in which the extension length of the side wall parts 15 and 16 and the magnitude | size of the seal lips 12 and 13 are substantially the same.
