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 includes a base portion and a vehicle body side wall portion extending from the base portion and a vehicle body side wall portion and a vehicle outer side wall portion. It has a car outer seal lip. The glass run is sealed so that the body portion is attached to a mounting portion (channel portion) provided along the inner periphery of the door frame, and the peripheral portions of the inner and outer surfaces of the door glass are sandwiched between both seal lips. Is done.

  In addition, the glass run is composed of an extrusion molding part formed in a substantially linear shape and a mold forming part that connects the extrusion molding parts at a predetermined angle, for example, along the shape of the door frame. The front vertical side portion, the upper side portion, and the rear vertical side portion (see, for example, Patent Document 1).

  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 the color and gloss of the surface are greatly different. Such a difference in color / gloss may also cause deterioration in appearance quality. Furthermore, a step is likely to be formed at the boundary portion (connecting portion) between the extrusion-molded portion and the mold-molded portion, which may cause a decrease in sealing performance.

  The mold forming part for forming the corner portion of the glass run includes a mold (core) for forming each inner peripheral surface of the main body, the vehicle inner side seal lip, and the vehicle outer side seal lip at the time of molding. In general, the inner side wall portion and the outer side wall portion of the vehicle are formed in an unfolded shape so that the holding strength of the core is maintained. However, when the vehicle inner side wall portion and the vehicle outer side wall portion are deformed so as to be narrowed when being attached to the attachment portion, the bending angle of the mold forming portion (corner portion) may change. In this case, the entire shape of the glass run does not follow the shape of the attachment portion, which may cause deterioration of the state of attachment to the attachment portion.

Further, it has also been proposed that the glass run is divided into a vehicle interior component and a vehicle exterior component, and the components are combined together later (see, for example, Patent Document 2).
JP 2006-8045 A US Pat. No. 5,396,733

  However, in the thing of patent document 2, since there is no restriction | limiting with respect to the shift | offset | difference of the width direction and longitudinal direction of both components at the time of the combination, it is difficult to combine both components correctly over the whole area, and depending on the case In addition, the sealing performance may be deteriorated or the state of attachment to the attachment portion may be deteriorated.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a glass run capable of improving the appearance quality, improving the sealing performance, stabilizing the mounting state, and the like. .

  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. A body portion attached to a mounting portion provided along the inner periphery of the vehicle door frame, and having a substantially U-shaped cross section comprising a base portion, a vehicle inner side wall portion and a vehicle outer side wall portion extending from the base portion; A glass run comprising an inner seal lip and an outer seal lip extending from substantially the front end of the vehicle inner side wall and the vehicle outer side wall to the inside of the main body,
By dividing the vehicle inner side and the vehicle outer side at any part of the main body portion, and forming the vehicle inner side molded body and the vehicle outer side molded body,
The vehicle interior mold body and the vehicle exterior mold body are each provided with engagement means for engaging and assembling both of them.
By assembling the vehicle interior mold body and the vehicle exterior mold body by the engaging means, the vehicle interior direction of the vehicle exterior mold body relative to the vehicle interior mold body, and the vehicle interior mold body The longitudinal movement of the upper side portion corresponding to the upper edge portion of the door glass and the front vertical side portion and the rear vertical side portion corresponding to the front edge portion and the rear edge portion of the door glass are restricted. A glass run characterized in that the entire direction is constructed.

  According to the means 1, the longitudinal direction entire region of the glass run is constituted by the vehicle interior mold body and the vehicle exterior mold body. In other words, the glass run can be constituted only by the molded body. For this reason, the situation where the connection line of an extrusion molded object and a molded object appears in an external appearance like the case where a glass run is comprised with an extrusion molded object and a molded object, for example can be avoided. Further, it is possible to avoid a situation in which a difference in color / gloss occurs in the longitudinal direction (circumferential direction) of the glass run. As a result, the appearance quality is improved. Moreover, the possibility that a step is formed in the longitudinal direction of the glass run can be avoided, and the sealing performance can be improved.

  Furthermore, since the glass run is composed of a vehicle interior mold body and a vehicle exterior mold body that are molded separately, the glass run can be expanded so that the vehicle inner side wall portion and the vehicle outer side wall portion are widened. It is not necessary to form so that the cross-sectional shape can be made to be a shape that does not need to be greatly deformed when attaching to the attachment portion. Accordingly, it is possible to stabilize the mounting state of the glass run with respect to the mounting portion (improvement of sealing performance) and the like. In addition, since the molded product has a higher degree of freedom in product design than the extruded product, for example, even when the cross-sectional shape is different at a specific part (for example, providing a protrusion, shortening the seal lip, etc.) It can be easily formed by mold forming. For this reason, it is possible to avoid a situation in which a separate operation (process) is required in order to make the cross-sectional shape different in the specific part, thereby improving productivity.

  Also, for example, when connecting the vehicle interior mold body and the vehicle exterior mold body with an adhesive, it takes time until the adhesive dries, or the vehicle interior mold body and the vehicle exterior mold body are bonded. Due to the necessity of holding the agent application surfaces in pressure contact with each other, there is a possibility that the manufacturing workability may be reduced. In particular, when the adhesive protrudes from the boundary surface (connection surface) between the vehicle interior mold body and the vehicle exterior mold body, for example, the sliding performance of the door glass is reduced, or the glass run attachment portion There is a risk that the mounting state to the will become unstable. In this regard, the engagement means is provided as in the present means 1, and the reduction in work efficiency can be suppressed by directly assembling the vehicle interior mold body and the vehicle exterior mold body.

  Further, the vehicle interior mold body and the vehicle exterior mold body are assembled by the engaging means, so that the vehicle exterior mold body with respect to the vehicle interior mold body in the vehicle width direction and the vehicle interior mold body in the longitudinal direction. The displacement movement is regulated. For this reason, the vehicle interior mold body and the vehicle exterior mold body can be assembled accurately, and the assembled state can be stabilized. Accordingly, the vehicle interior mold body and the vehicle exterior mold body are displaced or separated from each other, resulting in a decrease in sealing performance, a deterioration in the mounting state on the mounting portion, and a decrease in mounting workability. Fear etc. can be prevented.

  The engaging means may be provided in the entire region along the longitudinal direction of the vehicle interior mold body and the vehicle exterior mold body, or may be provided intermittently or partially.

The main body 11 includes a base portion 14 fitted into the channel portion DC, 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 as a whole. The vehicle outer side seal lip 12 extends from substantially the front end of the vehicle outer side wall portion 15 toward the inner peripheral side of the main body portion 11, and the vehicle inner side seal lip 13 extends from the substantially front end of the vehicle inner side wall portion 16 to the inner peripheral side of the main body portion 11. It extends toward. When the door glass DG is closed, the vehicle outer side seal lip 12 is pressed against the outer side surface of the door glass DG, and the vehicle inner side seal lip 13 is pressed against the inner side surface of the door glass DG. Thereby, the vehicle exterior side and vehicle interior side of the door glass DG are each sealed. Further, an exterior design lip 17 extending from the exterior side wall 15 toward the outside (the exterior of the vehicle) and an interior design lip 18 extending from the interior side wall 16 toward the exterior (the interior of the vehicle) are provided. Yes.

  The front vertical side 3 and the rear vertical side 4 are also provided with a main body 11 and a pair of seal lips 12 and 13. However, a portion of the glass run 1 which is disposed in the door panel 53 below the belt line and does not appear in appearance (in this example, the lower part of the front vertical side 3 and the rear vertical side 4) is outside the vehicle. The design lip 17 and the vehicle interior design lip 18 are omitted, and the sash part DS to which such a part is attached is miniaturized. The vehicle exterior seal lip 12 is configured to be smaller (shorter) than the vehicle interior seal lip 13. As a result, the door glass DG is brought to the outside of the vehicle, and a flash surface is achieved.

  Now, the glass run 1 in this embodiment is comprised by two type | mold molded bodies so that it may be divided | segmented into the vehicle outer side and the vehicle inner side in the vehicle width direction approximate center part of the base part 14. FIG. More specifically, as shown in FIG. 2 and FIG. 3, the glass run 1 includes a vehicle outer side seal lip 12, a vehicle outer side wall portion 15, and a base portion 14. 14a) is integrally molded, the vehicle interior side seal lip 13, the vehicle interior side wall portion 16, and the vehicle interior half of the vehicle base portion 14 (hereinafter referred to as vehicle interior base). And a vehicle interior mold body 22 formed integrally with each other. In FIG. 3, the portion corresponding to the upper side portion 2 of the vehicle exterior mold body 21 and the vehicle interior mold body 22 constituting the glass run 1 is divided and illustrated in the longitudinal intermediate portion. This is for the sake of convenience, and the vehicle exterior mold body 21 and the vehicle interior mold body 22 are continuous throughout the longitudinal direction of the glass run 1.

  In addition, the vehicle exterior mold body 21 and the vehicle interior mold body 22 include engagement means for engaging and assembling both. The engaging means in the present embodiment includes a locking convex portion 25 as an inboard engagement means integrally formed so as to protrude from the front end surface of the inboard base piece portion 14b extending from the inboard side wall portion 16, and the outboard side wall. The outer side base piece 14a extending from the portion 15 is formed of a locking recess 26 as an outer side engagement means formed so as to be cut out at the front end portion outer surface side. Then, by engaging the locking convex portion 25 with the locking concave portion 26, the front end surface of the vehicle outer base piece portion 14a and the front end surface of the vehicle inner base piece portion 14b are in contact with each other. The vehicle exterior mold body 21 and the vehicle interior mold body 22 are assembled. Moreover, the latching convex part 25 is comprised by the trapezoid shape which becomes wide toward the front-end | tip part side, and the latching recessed part 26 has comprised the shape corresponding to this. For this reason, it is difficult for the vehicle outer base piece portion 14a and the vehicle inner base piece portion 14b to be separated in the vehicle width direction by fitting the locking convex portion 25 to the locking concave portion 26. ing.

  In addition, the locking recess 26 does not penetrate in the thickness direction of the base portion 14, but is formed so that the front end portion outer surface side of the vehicle outer base piece portion 14a is cut out as described above. A bottom wall portion 27 constituting the bottom surface of the locking recess 26 is formed on the inner peripheral side of the locking recess 26. Then, in the assembled state of the vehicle exterior mold body 21 and the vehicle interior mold body 22, the bottom wall portion 27 and the locking projection 25 come into contact with each other, whereby the vehicle exterior base piece in the thickness direction of the base portion 14. Positioning of the vehicle interior base piece 14b (locking protrusion 25) with respect to the portion 14a (locking recess 26) is performed.

  For the front vertical side 3 and the rear vertical side 4, a locking projection 28 is formed on the vehicle outer base piece 14 a side, and a locking recess 29 is formed on the vehicle inner base piece 14 b side. . Further, as shown in FIG. 3, the locking projections 25, 28 and the locking recesses 26, 29 are provided at a plurality of locations at predetermined intervals in the longitudinal direction of the vehicle exterior mold body 21 and the vehicle interior mold body 22. It is formed one by one. As a result, it is possible to prevent a situation in which the vehicle exterior mold body 21 and the vehicle interior mold body 22 are displaced in the longitudinal direction.

  In addition, in the present embodiment, an attachment from the vehicle inner base piece portion 14b to the channel portion DC is provided at an end portion on the front vertical side portion 3 side of a portion corresponding to the upper side portion 2 of the vehicle inner side molded body 22. A protrusion 31 protruding in the direction side (upward) is integrally provided. The protrusion 31 is formed simultaneously with the molding of the vehicle interior mold body 22. Further, as shown in FIG. 1, the protrusion 31 is engaged with the channel portion DC in a state in which the projection 31 is fitted in the insertion hole 32 formed in the channel portion DC in the attachment state of the glass run 1 to the channel portion DC. Stopped. Thereby, when the door glass DG is closed (when the door glass DG comes into contact with the base portion 14 of the upper side portion 2), it is possible to prevent a situation in which the glass run 1 is displaced backward. it can.

  Further, in the present embodiment, as shown in FIG. 2, at least the boundary portion between the vehicle outer base piece portion 14 a and the vehicle inner base piece portion 14 b is covered, A polyethylene (PE) tape 35 is attached to the side surface. Thereby, the slidability of the door glass DG is improved. Moreover, as for the base part 14 comprised by the vehicle outer side base piece part 14a and the vehicle inner side base piece part 14b, the sticking surface of PE tape 35 is a flat surface (surface flush).

  Next, the manufacturing method of the glass run 1 is demonstrated. First, the vehicle exterior mold body 21 and the vehicle interior mold body 22 are respectively molded. Here, the manufacturing method of the vehicle interior mold body 22 will be briefly described. The vehicle interior mold body 22 is molded using a mold apparatus 41 as shown in FIG. That is, the mold apparatus 41 includes a first mold 42, a second mold 43, a third mold 44, a fourth mold 45, and a fifth mold 46. The first mold 42, the third mold 44, the fourth mold 45, and the fifth mold 46 are formed with molding surfaces corresponding to the outer shape of the vehicle interior mold body 22, respectively. Thus, a cavity 47 for molding the vehicle interior mold body 22 is formed. Then, the EPDM plasticized by the injection means 48 is injected into the cavity 47 through the sprue 49a formed in the first mold 42, the sprue 49b formed in the third mold 44 and the gate 50, Fill. Thereafter, the EPDM is vulcanized and solidified, and after the solidification is completed, the inside mold body 22 formed by opening the mold is removed from the mold apparatus 41. The vehicle interior mold body 22 is manufactured as described above. The vehicle exterior mold body 21 is also manufactured by molding in the same manner as the vehicle interior mold body 22 using a corresponding mold device.

  Subsequently, the vehicle exterior mold body 21 and the vehicle interior mold body 22 that have been molded as described above are assembled. That is, corresponding to the upper side portion 2, the locking convex portion 25 provided on the vehicle interior side molded body 22 is fitted to the locking concave portion 26 provided on the vehicle outside side molded body 21, and the front vertical side portion 3 and the rear vertical side portion 4 are engaged with a locking convex portion 28 provided on the vehicle exterior side mold body 21 in a locking concave portion 29 provided on the vehicle interior side mold body 22. Thereby, the cross-sectional shape having the main body 11 and the seal lips 12, 13 is formed as described above, and the upper side 2, the front vertical side 3, the rear vertical side 4, and the upper side 2 and the front vertical side 3 are formed. , The entire longitudinal direction of the glass run 1 main body including the connecting portion (corner portion) with the rear vertical side portion 4 is configured.

  Then, the glass run 1 is manufactured by sticking the PE tape 35 on the inner surface of the base portion 11.

  As described above in detail, in the present embodiment, the engagement protrusions 25 and 28 are fitted into the engagement recesses 26 and 29, and the vehicle exterior mold body 21 and the vehicle interior mold body 22 are assembled. The displacement movement in the vehicle width direction of the vehicle exterior mold body 21 with respect to the vehicle interior mold body 22 and the longitudinal direction of the vehicle interior mold body 22 is restricted, and the upper side portion 2, the front vertical side portion 3, and the rear vertical length The entire longitudinal direction of the glass run 1 composed of the side portions 4 is formed. That is, the glass run 1 can be composed only of a molded body. For this reason, for example, the case where the connecting line between the extrusion molded body and the molded body appears in the appearance as in the case where the glass run 1 is formed by connecting the extruded body and the molded body in the longitudinal direction. It can be avoided. Moreover, since the glass run 1 (glass run 1 main body) can be comprised with a single raw material, the situation where the difference of a color and gloss will arise in the longitudinal direction (circumferential direction) of the glass run 1 partially. It can be avoided. As a result, the appearance quality is improved. Moreover, the possibility that a step is formed in the longitudinal direction of the glass run 1 can be avoided, and the sealing performance can be improved.

  Further, since the glass run 1 is composed of the vehicle outside mold body 21 and the vehicle interior mold body 22 that are separately molded, the vehicle run side wall portion 15 and the vehicle interior side wall portion 16 are divided into the glass run 1. It is not necessary to form the expanded shape so as to spread widely, and it is possible to obtain a shape that does not need to greatly change the cross-sectional shape when attaching to the channel portion DC (sash portion DS). Therefore, stabilization of the attachment state of the glass run 1 with respect to the channel part DC (improvement of sealing performance) can be achieved. In addition, since the vehicle exterior mold body 21 and the vehicle interior mold body 22 are each molded, each mold molded body 21, The die structure for molding 22 can be simplified.

  In addition, since the molded product has a higher degree of freedom in product design than the extruded product, for example, even when the cross-sectional shape is different at a specific part (for example, providing a protrusion, shortening the seal lip, etc.) It can be easily formed by mold forming. For this reason, it is possible to avoid a situation where a separate operation is required in order to make the cross-sectional shape different in the specific part, thereby improving productivity. In addition, in this embodiment, about the site | part (the lower part of the back vertical side part 4, and the front vertical side part 3) below the belt line among the glass runs 1, it is comprised in the shape which abbreviate | omitted the design lips 17,18. However, no separate operation such as cutting the design lips 17 and 18 is performed, and the outer side molded body 21 and the inner side molded body 22 are formed simultaneously with the other parts.

  In addition, generally, the molded body has a smaller cross-sectional variation (manufacturing error) than the extruded molded body, and the glass run 1 (glass run 1 body) in this embodiment is only the molded body (21, 22). Therefore, the quality can be improved. In addition, compared with the case where the glass run 1 is constituted by an extrusion molded body and a molded body, according to the present embodiment, the trouble of manufacturing, inspecting, and assembling the molded body is eliminated. can do. As a result, work efficiency can be improved, facilities can be simplified, and as a result, productivity can be improved and costs can be reduced.

  Further, for example, when the vehicle exterior mold body 21 and the vehicle interior mold body 22 are connected by an adhesive, it takes time for the adhesive to dry, or the vehicle exterior mold body 21 and the vehicle interior mold molding. It may be necessary to hold the adhesive-coated surfaces of the body 22 in a state where they are in pressure contact with each other. In particular, when the adhesive protrudes from the connection surfaces (the front end surface of the vehicle outer base piece portion 14a and the front end surface of the vehicle inner base piece portion 14b) to the inner surface and the outer surface of the base portion 14, for example, the door glass DG There is a risk that the slidability of the glass run 1 will be lowered, or that the mounting state of the glass run 1 to the channel part DC will become unstable.

  In this regard, as in the present embodiment, engaging means (locking convex portion 25, locking concave portion 26) are provided, and the vehicle exterior mold body 21 and the vehicle interior mold body 22 are directly assembled in the engagement means. Thus, a decrease in manufacturing workability can be suppressed. Further, the locking convex portion 25 includes the front end surface of the vehicle interior base piece portion 14b and the front end surface of the vehicle exterior base piece portion 14a which are brought into contact with each other in the assembled state of the vehicle exterior mold body 21 and the vehicle interior mold body 22. Are provided so as not to protrude from the inner surface and the outer surface of the base portion 14. For this reason, it is possible to avoid a risk that a step is formed on the inner peripheral side or the outer peripheral side of the main body 11 by the engaging means. Accordingly, it is possible to prevent the possibility that the sliding property of the door glass DG is lowered or the attachment state of the glass run 1 to the channel portion DC becomes unstable.

  Further, by assembling the vehicle exterior mold body 21 and the vehicle interior mold body 22, the vehicle width direction of the vehicle exterior mold body 21 with respect to the vehicle interior mold body 22 and the longitudinal direction of the vehicle interior mold body 22. Deviation movement is restricted. For this reason, the vehicle exterior side molded body 21 and the vehicle interior side molded body 22 can be assembled accurately, and the assembled state can be stabilized. Therefore, due to the displacement and separation of the vehicle exterior mold body 21 and the vehicle interior mold body 22, the sealing performance is deteriorated, the attachment state to the attachment portion is deteriorated, and the attachment workability is deteriorated. It is possible to prevent the risk of being invited.

  Further, for example, if the glass run 1 is divided into the vehicle outer mold body 21 and the vehicle inner mold body 22 at or near the base of the seal lip 12 or 13, one mold molded body 21, 22 is molded. Therefore, there is a risk of complicating the mold structure. In this regard, according to the present embodiment, since the glass run 1 is divided into the vehicle outer mold body 21 and the vehicle inner mold body 22 in the base portion 14, the complexity of the mold structure can be suppressed and the design can be reduced. The degree of freedom increases. In addition, the boundary portion (connection line) between the vehicle exterior mold body 21 and the vehicle interior mold body 22 can be reliably positioned on the inner peripheral side of the channel portion DC, and the boundary portion appears in appearance. Thus, it is possible to prevent the possibility that the appearance quality is deteriorated.

  In the present embodiment, the PE tape 35 is attached to the base portion 14 so as to cover the assembly portion (connecting portion, boundary portion) between the vehicle exterior mold body 21 and the vehicle interior mold body 22. . For this reason, it is possible to stabilize the assembled state of the vehicle exterior mold body 21 and the vehicle interior mold body 22. Furthermore, since the sticking surface of the PE tape 35 in the base portion 14 is a flat surface, the PE tape 35 can be satisfactorily stuck and the sliding surface of the door glass DG becomes uneven. Such a risk can be 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 said embodiment, the glass run 1 is divided | segmented into the vehicle outer side (vehicle outer side molded object 21) and the vehicle inner side (vehicle inner side molded object 22) in the vehicle width direction approximate center part of the base part 14. FIG. However, it is not particularly limited to such a configuration, and the glass run 1 only needs to be divided into the vehicle exterior mold body 21 and the vehicle interior mold body 22 in any part of the main body 11. For example, the glass run 1 may be divided into the vehicle exterior mold body 21 and the vehicle interior mold body 22 at an intermediate portion of the vehicle interior side wall portion 16. However, from the viewpoint of suppressing the complication of the mold, the glass run 1 is formed on the vehicle outer mold 21 in the base portion 14 or in the vicinity thereof (near the root portion of the vehicle outer side wall portion 15 or the vehicle inner side wall portion 16). It is desirable to divide it into a vehicle interior mold body 22.

  (B) The configuration of the engaging means in the above embodiment is not particularly limited, and the vehicle exterior side molded body 21 (vehicle exterior base piece 14a) and the vehicle interior mold body 22 (vehicle interior base piece 14b). Can be positioned in the width direction and the longitudinal direction of the glass run 1, and any configuration that can directly engage (connect) them can be used. Hereinafter, exemplary embodiments will be described with reference to the drawings. FIG. 5A is a cross-sectional view showing the vehicle exterior side mold body 21 and the vehicle interior side mold body 22 in another embodiment, and FIGS. 5B to 5D are vehicle exterior base pieces in another embodiment. It is sectional drawing which shows the part 14a and the vehicle inside base piece part 14b. FIG. 6A is a partial perspective view showing an outer base piece 14a and an inner base piece 14b according to another embodiment, and FIG. 6B is a cross-sectional view taken along line XX of FIG. 6A. It is. FIG. 7A is a partial perspective view showing an outer base piece 14a and an inner base piece 14b according to another embodiment, and FIG. 7B is a cross-sectional view taken along line YY of FIG. 7A. It is. FIG. 8 is an exploded perspective view showing an outer base piece 14a and an inner base piece 14b according to another embodiment. FIGS. 9A and 9B are cross-sectional views showing modifications of the vehicle outer base piece 14a and the vehicle inner base piece 14b shown in FIG.

  For example, as shown in FIGS. 5 (a) to 5 (d), the front end surface of the vehicle interior base piece portion 14b has a substantially circular cross section at the front end with respect to the substantially central portion in the thickness direction of the vehicle interior base piece portion 14b. Engagement projections 61a, 61b, 61c, 61d having a diameter-enlarged portion formed in a substantially triangular shape (arrow shape), a substantially diamond-shaped cross section, and the like, and the vehicle exterior side of the front end surface of the vehicle exterior base piece 14a. Engagement holes 63a, 63b, 63c, and 63d for engaging and engaging the engagement protrusions 61a, 61b, 61c, and 61d may be formed with respect to a substantially central portion in the thickness direction of the side portion 14a. In this case, the engaging protrusions 61a, 61b, 61c, 61d and the engaging holes 63a, 63b, 63c, 63d constitute the engaging means. Further, by adopting this configuration, it is possible to suppress the possibility that the vehicle exterior mold body 21 and the vehicle interior mold body 22 are separated in the vehicle width direction, and the vehicle interior mold body 22 is configured as the vehicle exterior mold. It is possible to suppress the possibility of detachment from the molded body 21 in the attachment direction to the channel part DC (the thickness direction of the base part 14).

  Note that the engaging projections 61, 61b, 61c, and 61d and the engaging holes 63a, 63b, 63c, and 63d shown in FIGS. As in the case of the locking recesses 26 and 29, it is desirable that a plurality of pieces are formed at a plurality of locations at predetermined intervals in the longitudinal direction of the vehicle exterior mold body 21 and the vehicle interior mold body 22. In this case, it is possible to prevent a situation in which the vehicle exterior mold body 21 and the vehicle interior mold body 22 are displaced in the longitudinal direction. As a result, the vehicle exterior mold body 21 and the vehicle interior mold body 22 can be assembled accurately.

  Further, for example, as shown in FIGS. 6A and 6B, the locking projection 25 in the above embodiment is a main body in the assembled state of the vehicle exterior mold body 21 and the vehicle interior mold body 22. It is formed so as to be alternately exposed on the inner peripheral surface side of the portion 11 and the outer peripheral surface side of the main body portion 11, and the locking concave portion 26 is made to correspond to the locking convex portion 25 (the locking concave portion 26 is alternately exposed on the inner peripheral surface side of the main body part 11 and the outer peripheral surface side of the main body part 11 in a state before the vehicle outer mold body 21 and the vehicle inner mold body 22 are assembled. May be formed). In this case, since the locking projections 25 and the locking recesses 26 are alternately engaged along the longitudinal direction of the glass run 1, the in-car molded product 22 is attached to the channel portion DC from the out-car molded product 21. It is possible to suppress the risk of leaving in the direction.

  Furthermore, for example, as shown in FIGS. 7A and 7B, the locking convex portion 25 and the bottom wall portion 27 are configured to have a substantially L-shaped cross section when cut in the vehicle width direction. It is good also as restrict | limiting that both separate in the vehicle width direction at the time of the assembly | attachment of the vehicle exterior type molded object 21 and the vehicle interior mold molded object 22. As shown in FIG.

  Further, for example, as shown in FIG. 8, the longitudinal direction of the glass run 1 with respect to the surface of the locking projection 25 facing the bottom wall 27 and the surface of the bottom wall 27 facing the locking projection 25. Protrusions 67a, 67b and holes 68a, 68b are alternately provided along the direction, and the protrusions 67a provided on the locking protrusions 25 are fitted into the holes 68b provided on the bottom wall 27. The convex portion 67 b provided on the bottom wall portion 27 may be fitted into the hole portion 68 a provided on the locking convex portion 25. In this case, the convex portions 67a and 67b and the hole portions 68a and 68b provided on the locking convex portion 25 and the bottom wall portion 27 constitute the engaging means.

  Also, for example, as shown in FIG. 9A, by providing a minute undercut (expanded diameter portion 71) at the tip of the convex portions 67a and 67b shown in FIG. 67b and the holes 68a and 68b can be engaged with each other. The said enlarged diameter part 71 is good also as forming simultaneously with the vehicle outer side molded object 21 and the vehicle inner side molded object 22. FIG. Further, for example, when the convex portions 67a and 67b are made of TPO, as shown in FIG. 9B, the convex portion 67a is formed during molding of the vehicle exterior mold body 21 and the vehicle interior mold body 22. , 67b are formed so as to protrude from the corresponding holes 68, 68ab, and after assembling the vehicle exterior mold body 21 and the vehicle interior mold body 22, the protrusions 67a, 67b are formed at the tip portions. A diameter-expanded portion 71 as shown in FIG. 9A may be formed by performing so-called thermal welding that is crushed while applying heat to the surface.

  Of course, it is also possible to combine the engaging means as described above, or to adopt engaging means having different shapes partially (for example, the upper side portion 2, the front vertical side portion 3, and the rear vertical side portion 4). Is possible. The engaging means may be formed (continuously) over the entire length of the glass run 1 or may be formed intermittently or partially.

  (C) In the above embodiment, the protrusion 31 is simultaneously molded when the vehicle interior mold 22 is molded. For example, when the vehicle interior mold 22 is molded, one of the protrusions 31 is formed. The protrusion 31 may be formed by insert molding so that the portion is embedded in the vehicle interior base piece 14b. In this case, the protrusion 31 can be made of a material harder than the base portion 14, and the displacement movement of the glass run 1 when the door glass DG is closed can be more reliably prevented. The protrusion 31 can be omitted.

  (D) In the above embodiment, the vehicle exterior mold body 21 and the vehicle interior mold body 22 can be connected (assembled) by providing the engagement means, and further, PE is formed on the inner surface of the base portion 14. Although the tape 35 is attached to stabilize the assembled state, it is not particularly limited to such a configuration. For example, it is possible to omit the PE tape 35 and connect the vehicle exterior mold body 21 and the vehicle interior mold body 22 only with the engaging means.

  Further, for example, the vehicle exterior mold body 21 and the vehicle interior mold body 22 may be connected by an adhesive. However, when an adhesive is used, it takes time for the adhesive to dry, or the adhesive-coated surfaces of the vehicle interior mold body 22 and the vehicle exterior mold body 21 are held in pressure contact with each other. There is a possibility that manufacturing workability may be reduced due to the necessity. There is also a concern that the adhesive protrudes from the connection surface. From this point of view, it is desirable to connect the vehicle exterior mold body 21 and the vehicle interior mold body 22 by the engaging means as in the above embodiment.

  Further, for example, the engagement means (the locking projections 25 and 28, the locking recesses 26 and 29) are omitted, and the vehicle exterior mold body 21 and the vehicle interior mold body 22 are formed using only a tape material such as the PE tape 35. Can also be connected. However, in this case, it is preferable to stick the tape material on both the inner and outer surfaces of the base portion 14 in order to stabilize the assembled state. However, the workability decreases, the thickness of the base portion 14 increases, and the tape material increases. There are concerns about the occurrence of defects due to sticking errors. From this point of view, as in the above embodiment, the vehicle outer base piece portion 14a and the vehicle inner base piece portion 14b can be positioned in the thickness direction of the base portion 14, and the thickness of the base portion 14 is changed. It is desirable to connect the vehicle exterior mold body 21 and the vehicle interior mold body 22 by engagement means that does not occur.

  (E) The cross-sectional shape of the glass run 1 is not particularly limited as long as it includes at least the main body 11 and the pair of seal lips 12 and 13. For example, the design lips 17 and 18 may be omitted. Although not particularly mentioned in the above embodiment, in FIG. 2 and the like, a notch is formed in the vehicle outer side wall portion 15 and the boundary portion between the vehicle inner side wall portion 16 and the base portion 14. In the conventional technology in which the main body portion, the vehicle outer side seal lip, and the vehicle inner side seal lip are simultaneously formed, it is necessary to form the glass run in a developed shape. It is formed for the purpose of making it easy to close the wall. According to the above embodiment, the glass run 1 is divided and molded into the vehicle exterior mold body 21 and the vehicle interior mold body 22. The cut portion can be omitted. However, the PE tape 35 is attached to the inner surface of the base portion 14 of the glass run 1 in the assembled state of the vehicle exterior mold body 21 and the vehicle interior mold body 22 as in the above embodiment. In such a case, the workability is improved when the cut portion is provided. Instead of the PE tape 35, a sliding layer may be formed by applying a lubricant to the inner surface of the base portion 14. In this case, even if the notched portion is not provided, the lubricant is easily and reliably applied to the inner peripheral surface of the main body portion 11 before assembly of the vehicle exterior mold body 21 and the vehicle interior mold body 22. Can be applied.

  In order to improve the slidability of the seal lips 12 and 13, for example, in the case of urethane coating, flocking, or affixing a polyethylene (PE) tape, a vehicle exterior mold is formed. It is desirable to carry out at a stage where the body 21 and the vehicle interior mold body 22 are separated. In this case, as in the case where these operations are performed after the assembly of the vehicle exterior mold body 21 and the vehicle interior mold body 22, the vehicle exterior side wall portion 15 and the vehicle interior side wall portion 16 are expanded and expanded. Can be avoided, and workability can be improved.

  (F) In the above embodiment, the main body 11 and the seal lips 12 and 13 (the vehicle outer side molded body 21 and the vehicle inner side molded body 22) are made of EPDM, but are made of another material such as TPO. May be. Note that the glass run 1 may be colored in accordance with the color of the vehicle outer plate, regardless of which material such as rubber or TPO is used. Further, in the above embodiment, since the vehicle outer mold body 21 and the vehicle inner mold body 22 are divided, the glass run 1 (the vehicle outer mold body 21 and the vehicle inner mold body 22) is removed from the vehicle. It can also be colored according to the plate color and the interior color. Further, in the above embodiment, the glass run 1 for the front door has been described in detail. However, the glass run for the rear door or the like may be similarly configured from the vehicle exterior mold body 21 and the vehicle interior mold body 22. Good.
