Description

  The present invention relates to a glass run attached to a vehicle door.

  In general, a vehicle door such as an automobile is provided with a glass run for sealing a peripheral portion of a sliding door glass. The glass run has a substantially U-shaped cross-section main body and a pair of seal lips extending inward from the front ends of both side walls of the main body to the inner side of the main body. It is engaged with a U-shaped sash. And the vehicle inner side and vehicle outer side surface of the peripheral part of the door glass are sealed by the pair of seal lips.

  However, in a portion where the sash cannot be provided, it is conceivable to employ another mounting structure different from the mounting structure as the glass run mounting structure.

  For example, as a mounting structure generally employed for a weather strip, there is a type of mounting structure in which a mounting base having a pair of engaging convex portions is fitted into a retainer having a pair of engaging concave portions. In this configuration, the retainer is formed in a substantially C-shaped cross section with a narrow opening on the opening side, and engagement recesses are formed at both ends of the retainer to engage the engagement projections of the mounting base. Then, the engagement strips provided at both ends of the weather strip mounting base are pushed into the engagement recesses of the retainer to attach the weather strip.

  When attaching the weather strip mounting base to the retainer, generally one engaging convex part of the mounting base is inserted into one engaging concave part of the retainer and the other engaging convex part is pushed into the other engaging concave part. The installation is completed. Here, if the thickness of the mounting base (engagement convex part) and the depth of the retainer (engagement concave part) are set to be substantially the same, the tip of the other engagement convex part gets over the opening of the retainer. Since the bottom portion of the mounting base comes into contact with the bottom portion of the retainer before, it may be difficult to perform the mounting operation. In view of this, the depth of the retainer (engagement recess) is usually set with a margin so that the gap is wider than the thickness of the mounting base (engagement projection).

Furthermore, the reaction force received from the opening edge of the retainer when the attachment base (engagement convex portion) is pushed into the retainer may interfere with the attachment operation. On the other hand, in order to reduce the reaction force and improve the mounting workability, the base portion is bent and deformed by contacting the opening edge of the retainer, and the engaging convex portion is pushed into the mounting portion relatively easily. Some types can do this. For example, the depth of the retainer is set to be relatively deeper than before, and the base portion is bent and deformed so as to be convex in the mounting direction (outside), thereby making it easier to push the base portion (engagement convex portion). Some have been made (for example, see Patent Document 1).
Japanese Utility Model Publication No. 5-262188

  However, as a result of the depth of the retainer (engagement recess) being set with a margin, in the weather strip mounting state, a gap is created between the mounting base and the bottom of the retainer. The mounting position becomes unstable and the mounting base may be detached from the retainer in some cases. As a result, there is a possibility that problems such as a decrease in sealing performance may occur. Further, in the type in which the base portion is bent and deformed so as to be convex in the mounting direction as in Patent Document 1, the depth of the retainer has to be set relatively deep, and thus the above problem occurs more. May be easier.

  Of course, the above problem can also occur when the mounting structure is adopted for a glass run.

  The present invention has been made to solve the above problems, and its purpose is to improve a glass run mounting workability and to improve the stability of the glass run mounting state. It is to provide.

  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 glass run attached to a vehicle door having a door glass that moves up and down,
A main body portion having a substantially U-shaped cross section consisting of a base portion and a vehicle inner side wall portion and a vehicle outer side wall portion extending from both ends of the base portion;
A pair of seal lips that extend from the vehicle interior side wall and the vehicle exterior side wall to the inside of the main body and seal with the door glass,
A pair of engaging convex portions provided on the main body portion so as to be engaged with a pair of engaging concave portions provided on a mounting portion having a substantially C-shaped cross section on the vehicle door side;

  According to the means 1, by providing the bent portion, when the glass run is attached, the bent portion is bent and deformed so as to be convex toward the inside of the main body, that is, both engagements are performed on the outer side of the main body. After inserting both engaging protrusions into the mounting part with the distance between the protrusions shortened, the bent part returns to its original state by releasing the bent state, and each engaging convex part is engaged with each engaging part. Fit into the recess. Therefore, even when the thickness of the engaging convex portion and the depth of the attaching portion (engaging concave portion) are set at substantially the same interval, the engaging convex portion can be fitted into the attaching portion (engaging concave portion) relatively easily. . In other words, it is not necessary to set the depth of the attachment portion (engagement recess) with an extreme margin. In the glass run attachment state, there is a gap between the engagement protrusion and the bottom of the attachment portion. It becomes difficult to be born. Therefore, rattling in the mounting direction of the glass run is less likely to occur. Furthermore, compared to the type that bends and deforms so as to be convex toward the outside of the main body part, the engagement convex part is not brought into contact with the opening edge of the attachment part and pushed into the attachment part, so There is no risk that the mounting workability is reduced by the reaction force received from the opening edge of the mounting portion. As a result, it is possible to improve the workability of attaching the glass run and improve the stability of the attached state of the glass run. In addition, since the bent portion is configured to bend and deform so as to protrude toward the inside of the main body, that is, the side into which the door glass enters, the bent deformation of the bent portion is regulated by the door glass, and the glass run In the inserted state, the problem that the engaging convex part is detached from the engaging concave part is very unlikely to occur.

The glass run according to means 2, characterized in that.

  According to the said means 3, the thickness of the site | part in which the bending part was provided can be made comparatively thin, without affecting the shape of the vehicle inner side wall part of the vehicle inner side wall part which is the side facing the door glass. . As a result, the vehicle inner side wall portion (bending portion) is easily bent and deformed, and the mounting workability can be further improved.

  Means 4. 4. The glass run according to means 2 or 3, wherein the bent part is thinner than the thickness of the other part of the vehicle interior side wall part.

  According to the above means 4, the bent portion is easily bent and deformed, so that the mounting workability can be further improved.

  Means 5. The glass run according to any one of means 2 to 4, wherein a notch is provided in the bent portion.

  According to the above means 5, the bent portion is easily bent and deformed, and the mounting workability can be further improved.

  Means 6. The glass run according to any one of means 2 to 5, further comprising an extending wall portion that extends from a front end of the vehicle interior side wall portion and is locked to a predetermined locking portion.

  According to the means 6, since the extension wall portion is provided, the bending portion can be bent and deformed using the extension wall portion as an operation portion, and therefore the bending portion is more easily bent and deformed. Further, the mounting workability can be improved. Furthermore, since the extending wall portion is locked to the predetermined locking portion, the stability of the glass run attachment state can be further enhanced.

  Mean 7 At least one of the pair of engaging convex portions includes an extending lip that extends from the engaging convex portion and elastically abuts or presses against the bottom portion of the mounting portion. The glass run according to any one of 1 to 6.

  According to the means 7, by providing the extending lip, the gap between the engaging convex portion and the bottom portion of the mounting portion is closed in the mounting state of the glass run, and the glass run in the mounting direction is rattled. Can be regulated. As a result, it is possible to further improve the stability of the mounting state of the glass run, thereby improving the sealing property and suppressing the generation of wind noise.

  Hereinafter, an embodiment will be described with reference to the drawings.

  As shown in FIG. 1, an automobile door (a front door in the figure: simply referred to as “door” in the figure) 1 as a vehicle door that can be opened and closed at an opening of an automobile body as a vehicle body is a door that can be raised and lowered. Corresponding to the outer peripheral shape of the door glass G, a glass run 2 made of EPDM (ethylene-propylene-diene copolymer rubber) is provided.

  The glass run 2 includes an extrusion molding portion 3 corresponding to the upper side portion in the longitudinal direction, extrusion molding portions 4 and 5 corresponding to the front and rear vertical side portions, and ends of the extrusion molding portions 3, 4 and 5. It is comprised from the shaping | molding parts 6 and 7 (part which attached | subjected the dot pattern in FIG. 1) to connect. Each of the extrusion molding portions 3 to 5 is formed in a substantially linear shape (in a long shape) by an extruder (not shown). In addition, the molding parts 6 and 7 are connected and molded by a mold apparatus (not shown) so that the two extrusion molding parts 3 and 4 and the extrusion molding parts 3 and 5 are connected to each other at a predetermined angle. Is done.

  Next, referring to FIGS. 2 to 4 which are partial sectional views taken along the line JJ of FIG. 1, the configuration of the upper side portion (extrusion molding portion) 3 of the glass run 2 and the attachment of the door 1 to which the glass run 2 is attached. The seal structure at the upper side of the door 1 will be described in detail based on the configuration of the part.

  First, the structure of the attachment part of the upper side part of the door 1 to which the upper side part 3 of the glass run 2 is attached is demonstrated. On the upper side portion of the door 1, the retainer S <b> 1 as an attachment portion disposed substantially parallel to the vehicle inner side surface of the door glass G and the end surface of the upper edge portion of the door glass G are disposed substantially opposite to each other. An exterior member S2 and an interior member S3 as a locking portion provided below the retainer S1 are provided.

  The retainer S1 includes a bottom wall portion 30 that constitutes a bottom portion that is disposed substantially parallel to the vehicle interior side surface of the door glass G, and a pair of upper and lower portions that are bent so that upper and lower ends of the bottom wall portion 30 are substantially opposed to each other. The folding | returning parts 31 and 32 are provided. That is, the retainer S1 has a substantially C-shaped cross section that opens toward the outside of the vehicle, and is provided with a pair of upper and lower engaging recesses 33 and 34 defined by the folded portions 31 and 32 at both upper and lower ends thereof.

  Next, the configuration of the upper side 3 of the glass run 2 will be described. The upper side portion 3 of the glass run 2 has a base portion 10 attached to the exterior member S2, and a main body portion 13 having a substantially U-shaped cross section including a vehicle inner side wall portion 11 and a vehicle outer side wall portion 12 extending from both ends of the base portion 10. A pair of seal lips 14 and 15 that extend inward from the vehicle interior side wall 11 and the vehicle exterior side wall 12 to the inside of the main body 13 and seal with the door glass G, and extend from the front end of the vehicle interior side wall 11. A pair of upper and lower portions provided on the vehicle inner side surface of the extended side wall portion 11 and the extended wall portion 16 whose leading end portion is locked to the interior member S3 and engaged with the engaging concave portions 33 and 34 of the retainer S1. Engaging protrusions 17 and 18 and an extending lip 20 extending from the engaging protrusion 17 on the upper side (base portion 10 side) and elastically contacting or press-contacting the bottom wall portion 30 of the retainer S1 are provided. Yes. The extension lip 20 is bent and formed in a substantially V-shaped cross section so as to extend from substantially the front end of the engagement protrusion 17 and to protrude toward the upper engagement recess 33 corresponding to the engagement protrusion 17. Yes.

  Further, a bent portion 22 for bending and deforming the vehicle inner side wall portion 11 to be convex toward the vehicle outer side is provided between the both engaging convex portions 17 and 18 in the vehicle inner side wall portion 11. The vehicle inner side surface of the vehicle inner side wall portion 11 is formed in a substantially V-shaped cross section so that the distance from the vehicle outer side surface of the vehicle inner side wall portion 11 gradually decreases from the engagement convex portions 17 and 18 to the bent portion 22. ing. The vehicle outer side wall 12 is formed to be relatively shorter than the vehicle inner side wall 11, and the vehicle outer seal lip 15 is relatively smaller (shorter) than the vehicle inner seal lip 14. ) Is set. Thus, the flash surface is formed so that the vehicle outer side surface of the exterior member S2 is substantially flush with the vehicle outer side surface of the door glass G.

  Then, the effect | action at the time of attaching the glass run 2 which has said structure is demonstrated. First, as shown in FIG. 3, the engaging convex portion 17 and the extending lip 20 are inserted into the engaging concave portion 33 on the upper side of the retainer S1 while attaching the base portion 10 and the vehicle outer side wall portion 12 to the exterior member S2. Subsequently, the extended wall portion 16 is operated to bend and deform the bent portion 22, and the vehicle inner side wall portion 11 (bent portion 22) is bent so as to be convex toward the vehicle outer side, that is, the lower engagement. The lower engaging convex portion 18 is inserted into the retainer S1 while keeping the joint convex portion 18 close to the upper engaging convex portion 17 (in the direction of the arrow in FIG. 3).

  And after inserting the engaging convex part 18 in retainer S1, the bending state of the vehicle interior side wall part 11 is cancelled | released. As a result, as shown in FIG. 4, the vehicle interior side wall portion 11 returns to its original state, and the lower engagement convex portion 18 is fitted into the lower engagement concave portion 34 of the retainer S1. And the front-end | tip part of the extension wall part 16 is latched by interior member S3, and attachment is completed.

  In the attached state of the glass run 2, the constricted part defined by the vehicle interior side wall part 11 and the engaging convex parts 17 and 18 is engaged with the folded parts 31 and 32 of the retainer S1, so The movement in the direction (the raising and lowering direction of the door glass G) is restricted. Further, the extended lip 20 contacts or presses against the bottom wall portion 30 of the retainer S1 while being elastically deformed. And the engagement convex part 17 is urged | biased by the inner wall surface of the engagement recessed part 33 with the elastic force of the said extension lip 20, and the movement to the vehicle inside / outside direction of the glass run 2 is controlled.

  As described in detail above, the vehicle interior side wall 11 is bent so as to be convex toward the outside (vehicle interior) of the vehicle interior side wall 11 by including the bent portion 22 that is bent and deformed so as to be convex toward the vehicle exterior. Compared to the deformable type, when the glass run 2 is attached, the engaging projections 17 and 18 are not brought into contact with the opening edge of the retainer S1 and pushed into the retainer S1. Further, there is no possibility that the mounting workability is lowered due to the reaction force received from the opening edge of the retainer S1. As a result, it is possible to improve the mounting workability of the glass run 2.

  Further, since the bent portion 22 is configured to bend and deform so as to protrude toward the inside of the main body portion 13, that is, the side into which the door glass G enters, the bent portion 22 is bent and deformed when the glass run G is inserted. Is restricted by the door glass G, and the problem that the engaging protrusions 17 and 18 are disengaged from the engaging recesses 33 and 34 is extremely unlikely to occur.

  Further, the inner side surface of the inner side wall portion 11 has a substantially V-shaped cross section so that the distance from the outer side surface of the inner side wall portion 11 gradually decreases from the engagement convex portions 17 and 18 to the bent portion 22. Since it is formed, the thickness of the portion provided with the bent portion 22 is made relatively thin without affecting the shape of the vehicle outer side surface of the vehicle inner side wall 11 that is the side facing the door glass G. Can do. As a result, the vehicle interior side wall portion 11 (bending portion 22) is easily bent and deformed, and further improvement in mounting workability can be achieved.

  Further, since the extending wall portion 16 is provided, the bent portion 22 can be bent and deformed by operating the extending wall portion 16, so that the bent portion 22 can be more easily bent and deformed, and further mounting workability can be improved. Improvements can be made. Furthermore, since the extended wall portion 16 is locked to the interior member S3, the stability of the attached state of the glass run 2 can be further enhanced.

  By providing the extended lip 20 that extends from the upper engaging convex portion 17 and elastically abuts or presses against the bottom wall portion 30 of the retainer S1, the engaging convex portion 17 and the retainer in the attached state of the glass run 2 are provided. The gap between the bottom wall portion 30 of S1 can be closed and the rattling of the glass run 2 in the vehicle interior / exit direction can be restricted. As a result, the stability of the attached state of the glass run 2 can be improved, and consequently the sealing performance can be improved, and the generation of wind noise can be suppressed.

  The extended lip 20 has a so-called lip shape and elastically abuts or presses against the bottom wall portion 30 of the retainer S1. Therefore, when the projecting portion such as a bead that abuts against the bottom wall portion 30 of the retainer S1 is provided. In comparison, the abutting area is increased, and the abutment is more reliably abutted against the bottom wall portion 30 of the retainer S1, and the above-described effects are more reliably exhibited. Furthermore, since the extended lip 20 is bent and formed in a substantially V-shaped cross section so as to protrude from the substantially distal end of the engaging convex portion 17 and to protrude toward the engaging concave portion 33, the elastic force is more reliably provided. In addition to being able to be obtained, the engaging convex portion 17 is easily fitted into the engaging concave portion 33. As a result, it is possible to suppress a decrease in work efficiency of the fitting work. As a result, since the protrusion amount increases by the extension of the extension lip 20, it becomes easy to insert the engagement convex portion 17, and the working efficiency can be improved.

  Further, since the engaging convex portion 17 is urged against the inner wall surface of the engaging concave portion 33 by the elastic force of the extending lip 20, the engaging convex portion 17 becomes difficult to come out of the engaging concave portion 33, and the glass run 2 The stability of the mounting state can be further increased.

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

  (A) In the above embodiment, the glass run 2 for the front door 1 is embodied, but the part of the door in which such a glass run 2 is adopted is not limited at all, and is applied to, for example, a rear door. You can also. Moreover, you may employ | adopt the structure provided with the said engagement convex parts 17 and 18, the bending part 22, etc. not only to the upper side part of the glass run 2, but the vertical side part of the glass run 2, for example.

  (B) In the above embodiment, the pair of upper and lower engaging projections 17 and 18 provided on the vehicle inner side surface of the vehicle inner side wall portion 11 are fitted into the retainer S1 that opens toward the vehicle outer side. Is configured to be mounted. However, the positions at which the engagement convex portions 17 and 18 are provided are not limited to the vehicle interior side wall portion. For example, it is good also as a structure by which the engagement convex parts 17 and 18 are provided in the base part 10, and the said engagement convex parts 17 and 18 are engage | inserted by the retainer opened toward the downward direction. In this case, a bent portion similar to the bent portion 22 is provided in the base portion 10.

  (C) The number, position, and shape of the extended lips 20 are not limited to the above embodiment. For example, the extending lip 20 may be extended from both the engaging protrusions 17 and 18. Further, the extension lip 20 may be configured to extend directly from the vehicle inner side surface of the vehicle inner side wall portion 11. Further, the shape is not limited to a bent shape having a substantially V-shaped cross section, and may be a substantially linear shape such as the seal lips 14 and 15.

  Further, the extended lip 20 may be omitted. In this case, the thickness of the engaging projections 17 and 18 and the depth of the retainer S1 (engaging recesses 33 and 34) can be made substantially the same interval. Even in this case, the engaging convex portions 17 and 18 can be fitted into the retainer S1 (engaging concave portions 33 and 34) relatively easily by the configuration of the above embodiment. In other words, it is not necessary to set the depth of the retainer S1 (engagement recesses 33, 34) with an extreme margin. In the mounted state of the glass run 2, the engagement protrusions 17, 18 and the retainer S1 A gap is less likely to be created between the bottom wall portion 30 and the bottom wall portion 30. As a result, it is difficult for the glass run 2 to rattle in and out of the vehicle, and the stability of the mounted state of the glass run 2 can be improved.

  (D) The thickness of the bent portion 22 may be thinner than the thickness of other portions of the vehicle interior side wall portion 11. Instead of or in addition to this configuration, the bent portion 22 may be provided with a notch. If it does in this way, the bending part 22 will become further easy to bend-deform, and it can aim at the further improvement of workability | operativity.
