Description

  The present invention relates to a glass run attached to a sash provided in a vehicle body or door.

  As shown in FIGS. 6A and 6B, the glass run 61 includes a base portion 62 and a main body portion 65 including a pair of side wall portions 63 and 64 extending from the base portion 62, and the both side wall portions 63 and 64. And a pair of seal lips 66 and 67 extending from the substantially distal end to the inside of the main body 65. The main body 65 is attached to a sash S provided on the main body or door of the vehicle, and the inside and outside of the door glass G are sealed by the pair of seal lips 66 and 67.

  In general, the glass run 61 is divided into an extrusion-molded portion and a mold-molded portion in the longitudinal direction. The extrusion molding part is formed substantially linearly (in a long shape) by an extruder (not shown). The mold forming portion mainly corresponds to the corner portion, and is formed with a predetermined mold so that the two extruded portions are connected to each other at a predetermined angle (for example, 90 degrees).

  Conventionally, as shown in FIG. 6 (a), in both the extruded portion and the molded portion, a state where a pair of side wall portions 63 and 64 are expanded with respect to the base portion 62, that is, both side wall portions 63 and 64 are in the base. It is molded in a state where it is opened outward from the base portion with the portion 62 as a base point. This is due to the following reason. First, regarding the extrusion molding part, (1) in consideration of applying a predetermined lubricant to the inner peripheral surface of the base part 62 and the sliding surfaces of the glass of the seal lips 66 and 67, the molded part in an unfolded state. (2) If the seal lips 66 and 67 are close to each other, the seal lips 66 and 67 may be connected to each other immediately after molding, and this is to prevent it. On the other hand, with respect to the molded part, it is convenient to (1) make the shape follow the extruded part, and (2) to define the inner peripheral surfaces of the main body 65 and the seal lips 66 and 67 during the molding. It is necessary to set the core, but in the case of a mold having a cavity in which the seal lips 66 and 67 are close to each other, a thickness sufficient for a holding plate for holding the core unless it is molded in the expanded state. It is because it cannot be given.

  As shown in FIG. 6 (b), the glass run 61 molded in the unfolded state as described above is constricted from the unfolded state to the non-deployed state when the side walls 63 and 64 are attached to the sash S. . In other words, in the attached state, the side wall portions 63 and 64 are moved inward, and the main body portion 65 has a substantially U-shaped cross section. At this time, when the door glass G is not present, the tip portions of the seal lips 66 and 67 are in contact with each other.

  However, in the above technique, when the mold forming part is narrowed when attaching to the S to the sash, each part of the mold forming part (corner part) is not uniformly deformed, and the bending angle based on the stress at that time (Curvature radius, circumference, etc.) may change. In this case, the overall shape of the glass run 61 may not follow the sash shape, and attachment failure may occur.

  On the other hand, it is conceivable to design the glass run 61 in the unfolded state in anticipation of such a change in angle, etc., but in this case, it is impossible to predict what kind of angle change will occur. Trial and error must be repeated, resulting in a significant increase in design man-hours.

On the other hand, the base portion is formed into a bellows-like stretchable portion that can be stretched in and out of the vehicle, and the stretchable portion that has been stretched before being attached to the sash is shrunk when attached, There is also a glass run that fits into the sash (see, for example, Patent Document 1).
JP-A-9-315161

  However, in the invention described in Japanese Patent Laid-Open No. 9-315161, a bellows-like stretchable portion is provided at a portion of the base portion facing the door glass, and the end surface of the door glass may abut against the stretchable portion. There is. For this reason, the door glass is swung in and out of the vehicle by the telescopic portion, the sliding position of the end surface of the door glass is not stable in the vertical side portion of the glass run, and the end surface of the door glass is in the upper side portion of the glass run. There is a possibility that the contact position is not stable, and that the sealing performance is deteriorated. Furthermore, when the contact of the end surface of the door glass with the expansion / contraction part is repeatedly performed, there is a possibility that the expansion / contraction part and thus the durability of the glass run may be hindered.

  The present invention has been made to solve the above problems, and an object thereof is to provide a glass run capable of improving the stability of the position of the door glass.

  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. Having an extrusion molded part formed by an extrusion molding method and a mold molding part formed by connection at the end of the extrusion molding part by a molding method;
A body portion attached to a vehicle body or a sash provided on a door, and having a substantially U-shaped cross section including 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 extending from the front end of the vehicle inner side wall and the vehicle outer side wall to the inside of the main body and sealing with the door glass,
A glass run formed on the base portion and having a stretchable portion that can be stretched in a vehicle interior and exterior direction,
In the position deviated from the facing part of the end face of the door glass in the base part, forming the stretchable part ,

The glass run characterized in that the thickness of the outer variable portion is thinner than the thickness of the inner variable portion .

  According to the means 1, even if the glass run is molded with the main body portion having a substantially U-shaped cross section in the non-deployed state, both the seal lips can be formed if the stretchable portion is molded in a state of extending in and out of the vehicle. A glass run having an open space can be obtained. As a result, even when a predetermined lubricant is applied, it can be easily applied to the inner peripheral surface of the base and the sliding surface of the glass of the seal lip, and both the seal lips are connected immediately after molding. The fear can be reduced. In addition, with respect to the molded part, the holding plate for holding the core of the mold can have a sufficient thickness. Furthermore, since it is not necessary to rotate and narrow the side wall portion in the mold forming portion from the unfolded state during the mounting operation, the angle, curvature radius, circumference, etc. of the mold forming portion do not change before and after the attachment. . Therefore, it is possible to avoid the problem that it is impossible to mount the sash along the shape of the sash. Further, in designing, it is not necessary to repeat trial and error in anticipation of the above change, so that the design man-hour can be reduced.

In addition, in the said means, since the said expansion-contraction part is formed in the position which remove | deviated from the opposing part of the end surface of the door glass in a base part, a possibility that the end surface of a door glass contact | abuts to an expansion-contraction part is reduced. Thereby, the sliding position and contact position of the end surface of the door glass are stabilized, and the sealing performance can be improved. Furthermore, the durability of the stretchable part and thus the glass run can be improved. It should be noted that the fact that the expansion / contraction part is “formed on the base” includes, of course, that it is “formed on the connecting portion between the base and the vehicle inner side wall or the vehicle outer side wall”.
In addition, when the glass run is attached to the sash, the stretchable portion is biased to a position that does not hinder the sliding or abutting of the end face of the door glass, and the above-described effect is more reliably exhibited.
Furthermore, unlike the case where the stretchable part has a bellows shape, the protrusions (bent parts) are not formed at a plurality of locations, so that the possibility that the end surface of the door glass contacts the stretchable part is further reduced. be able to.

Means 2 . Means 1 is characterized in that the stretchable part is configured so that at least a part thereof protrudes to the inside of the main body part from the facing surface side of the end face of the door glass of the base part at least in a contracted state. The glass run described.

According to the above means 2 , the glass run can be properly attached to the sash because the protrusion to the outside of the main body of the extendable part is prevented or suppressed. Furthermore, expansion and contraction section is, in the configuration that protrudes to the main part inside than the opposite side of the end face of the door glass of the base portion, similar conventionally, in the above trouble occurs tends, by the configuration of the unit 1, such You can get rid of any concerns.

Means 3 . The means 1 or 2 is characterized in that the expansion / contraction part is configured to be in an in-vehicle direction or an out-of-vehicle direction in a contracted state and inclined in a direction away from a facing part of the end surface of the door glass. The glass run described.

According to the means 3 , when the glass run is attached to the sash, the expansion / contraction part is biased to a position that does not hinder the sliding or abutting of the end face of the door glass, and the effect of the means is more reliably achieved. Will be.

Means 4 . The glass run according to any one of means 1 to 3, wherein a notch portion is provided at a base portion of the outer variable portion or in the vicinity thereof.

According to the means 4 , by forming the notch portion, when the expansion / contraction portion contracts, the deformation of the outer variable portion is promoted, and the expansion / contraction portion is more easily inclined in the direction of moving away.

Means 5 . 5. The glass run according to any one of means 1 to 4 , wherein the stretchable part is provided on the vehicle inner side than the facing part of the end face of the door glass.

According to said means 5 , compared with the case where an expansion-contraction part is provided in the vehicle outer side rather than the opposition site | part of the end surface of a door glass, a expansion-contraction part is a main-body part inner side rather than the opposing surface of the end surface of the door glass of a base part. Even in the case where the door glass protrudes, the possibility that the door glass shifts to the inside of the vehicle due to the stretchable portion is reduced. Therefore, an effective effect is exhibited even in the flush surface required in recent years, that is, in the flushing between the vehicle outer surface of the sash and the vehicle outer surface of the door glass from the viewpoint of improving the appearance quality and the like. .

[First Embodiment]
First, a first embodiment will be described with reference to the drawings. In a vehicle having an elevator door glass, as shown in FIG. 1, a glass run 1 made of EPDM (ethylene-propylene-diene copolymer rubber) is attached corresponding to the outer peripheral shape of the door glass. More specifically, the door is provided with a sash S (see FIG. 2B) having a substantially U-shaped cross section in accordance with the outer peripheral shape of the door glass, and the glass of the present embodiment is provided on the sash S. Run 1 is attached.

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

  As shown in FIGS. 2A and 2B, the extruded portions 2 to 4 and the molded portions 5 and 6 include a base portion 10 that is attached to the sash S and a vehicle inner side wall portion that extends from both ends of the base portion 10. 11 and a vehicle body side wall portion 12, and a main body portion 13 having a substantially U-shaped cross section. A pair of seal lips 14 and 15 for sealing is provided.

  The base portion 10 is formed with a stretchable portion 16 that can be stretched in the vehicle interior / exit direction. More specifically, the stretchable portion 16 is a section Z from the position intersecting with the extension line along the vehicle inner side surface of the door glass G in the base portion 10 to the position intersecting with the extension line along the vehicle outer side surface. The door glass G is provided at a position away from the facing portion of the end face of the door glass G. In this embodiment, it is provided in the vicinity of the connecting portion with the vehicle inner side wall portion 11 on the vehicle inner side than the facing portion of the end surface of the door glass G with respect to the vehicle inner / outer direction [vertical direction in FIG. It has been. That is, it is formed at a position that does not hinder the contact or sliding of the end surface of the door glass G.

  The expansion / contraction part 16 is comprised from the inner variable part 16a located in the vicinity of the opposing site | part of the end surface of the said door glass G, and the outer variable part 16b located in the distance, and it exists inside the main-body part 13 in the expansion | extension state. The cross section has a substantially V-shaped cross section, which is a convex shape, and protrudes to the inside of the main body portion 13 from the facing surface 10a of the end surface of the door glass G of the base portion 10. The stretchable portion 16 is thinner than the thickness of the base portion 10 body, and the thickness t of the outer variable portion 16b is thinner than the thickness T of the inner variable portion 16a.

  As shown in FIG. 2 (a), the glass run 1 is molded in a state where the extruding parts 2-4 and the mold forming parts 5, 6 are extended in the vehicle interior / exit direction. Therefore, before the attachment to the sash S, the vehicle interior side wall portion 11 and the vehicle exterior side wall portion 12 have dimensions corresponding to the expansion of the expansion and contraction portion 16 while the main body portion 13 maintains a substantially U-shaped cross section in a non-deployed state. A predetermined opening amount W is ensured between the seal lips 14 and 15 in a state of being translated parallel to both sides.

  When the glass run 1 is attached to the sash S, the telescopic portion 16 is contracted to translate the vehicle inner side wall portion 11 and the vehicle outer side wall portion 12 so that the main body portion 13 is in a substantially U-shaped cross section in a non-deployed state. The main body 13 can be easily fitted into the sash S while maintaining the above.

  The expansion / contraction part 16 is elastically deformed preferentially when the outer variable part 16b contracts due to the difference in the thickness of the variable parts 16a and 16b, and thus the in-vehicle direction (downward direction in FIG. 2B), that is, It will be in the state inclined in the direction away from the opposing site | part of the end surface of the said door glass G. As shown in FIG. Therefore, in a state where the glass run 1 is attached to the sash S, the stretchable portion 16 is biased to a position that does not hinder the sliding or abutting of the end face of the door glass G.

  As described above in detail, the glass run 1 is formed in a state in which the expansion / contraction part 16 is extended in the vehicle interior / exterior direction and the main body part 13 has a substantially U-shaped cross section in a non-deployed state. The body portion 13 is attached to the sash S in a state where the body portion 13 is contracted in the vehicle interior and exterior direction and has a substantially U-shaped cross section in a non-deployed state. Therefore, when the glass run 1 is formed, the gap between the seal lips 14 and 15 is opened, and a predetermined opening amount W is secured between the seal lips 14 and 15. As a result, even when a predetermined lubricant is applied, it can be easily applied to the inner peripheral surface of the base 10 and the glass sliding surfaces of the seal lips 14 and 15. The possibility that they will be connected can be reduced. Further, with respect to the mold forming portions 5 and 6, the holding plate for holding the core of the mold can have a sufficient thickness. Furthermore, since it is not necessary to rotate and narrow the side wall portions 11 and 12 in the mold forming portions 5 and 6 from the unfolded state at the time of mounting work, the angle, curvature radius, circumference, etc. of the mold forming portions 5 and 6 can be reduced. There is no change before and after installation. Therefore, it is possible to avoid a problem that the sash S cannot be attached along the shape of the sash S. Further, in designing, it is not necessary to repeat trial and error in anticipation of the above change, so that the design man-hour can be reduced.

  Moreover, since the expansion / contraction part 16 is provided in the position which remove | deviated from the opposing part of the end surface of the door glass G in the base part 10, a possibility that the end surface of the door glass G contact | abuts to the expansion / contraction part 16 is reduced. Thereby, the sliding position and contact position of the end surface of the door glass G are stabilized, and the sealing performance can be improved. Furthermore, the durability of the stretchable part 16 and thus the glass run 1 can be improved.

  In addition, in this embodiment, the expansion / contraction part 16 is provided in the vehicle inside rather than the opposing site | part of the end surface of the door glass G of the base part 10. FIG. For this reason, compared with the case where the expansion-contraction part 16 is provided in the vehicle outer side rather than the site | part which opposes the end surface of the door glass G of the base part 10, the door glass G raise | generates position shift to the vehicle inner side by the said expansion / contraction part 16. The fear is reduced. Accordingly, it is possible to achieve an effective effect even in the flush surface demanded in recent years, that is, in the flushing between the vehicle outer surface of the sash S and the vehicle outer side surface of the door glass G from the viewpoint of improving the appearance quality and the like. It becomes.

  Further, since the expansion / contraction part 16 protrudes to the inside of the main body part 13 from the facing surface 10a of the end face of the door glass G of the base part 10 and is prevented from protruding to the outside of the main body part 13 of the expansion / contraction part 16, the glass run 1 Can be properly attached to the sash S, and the movement of the door glass G toward the inside of the vehicle can be restricted by the expansion and contraction part 16, so that the position of the door glass G can be further stabilized.

[Second Embodiment]
Next, a second embodiment will be described with reference to the drawings. However, the detailed description of the same components as those in the first embodiment will be omitted, and only the stretchable part and the related parts will be described.

  As shown in FIGS. 3A and 3B, the base portion 10 is formed with a stretchable portion 21 that can be stretched in the vehicle interior and exterior directions on the vehicle inner side than the facing portion (section Z) of the end surface of the door glass G. Has been.

  The telescopic part 21 is composed of an inner variable part 21a located near the opposite part of the end face of the door glass G and an outer variable part 21b located far away. It has a substantially V-shaped cross section that is convex toward the top, and protrudes to the inside of the main body portion 13 from the facing surface 10a of the end surface of the door glass G of the base portion 10. Further, the thickness of the expansion / contraction part 21 is thinner than the thickness of the base 10 main body, and the thickness of the outer variable part 21b and the thickness of the inner variable part 21a are substantially the same. Of course, instead of this, the thickness of the outer variable portion 21b may be thinner than the thickness of the inner variable portion 21a. Further, a notch 22 having a substantially concave cross section as a notch is provided in the vicinity of the root of the outer variable portion 21b. In addition, although the notch 22 in this embodiment is provided in the inner surface of the main-body part 13, of course, it is good also as a structure provided in the outer surface.

  And since the expansion / contraction part 21 is formed with the notch 22, when it contracts, the deformation of the outer variable part 21 b is urged, and the interior direction (downward direction in FIG. 3A), that is, the door glass It will be in the state inclined in the direction away from the opposing site | part of the end surface of G. Therefore, in a state where the glass run 1 is attached to the sash S, the expansion / contraction portion 21 is biased to a position that does not hinder the sliding or contact of the end surface of the door glass G.

  As a result, the same effect as in the first embodiment is achieved.

  As shown in FIGS. 4A and 4B, the base portion 10 is formed with a stretchable portion 31 that can be stretched in the interior and exterior directions on the vehicle inner side than the facing portion (section Z) of the end surface of the door glass G. Has been.

  The expansion / contraction part 31 is connected to the wall surfaces of both base part main bodies 32a, 32b opposite to each other with the expansion / contraction part 31 in between, and has a substantially reverse cross-section that is convex toward the outside of the main body part 13 in the extended state. V-shaped. The stretchable part 31 is thinner than the thickness Y of the base part 10. Both ends of the expansion / contraction part 31 are connected to the thickness direction of the base part 10 on the wall surfaces of the base part main bodies 32a and 32b (the left-right direction in FIG. The portion is located inside the outer surface of the base portion 10. Accordingly, the stretchable portion 31 is configured to be within the thickness Y region of the base portion 10 in both the stretched state and the contracted state, and does not protrude to both the inside and outside of the main body portion 13.

  With the above configuration, the contact portions 32 c and 32 d of both base body bodies 32 a and 32 b that contact in the contracted state of the expansion / contraction part 31 are the doors of the base part 10 rather than the expansion / contraction part 31 in the thickness direction of the base part 10. It will be located in the opposing surface 10a side (inner side of the main-body part 13) of the end surface of the glass G. FIG.

  The abutting portions 32c and 32d are configured so that substantially the entire surface thereof is formed in a substantially planar shape that is substantially orthogonal to the facing surface 10a of the end surface of the door glass G, and is brought into surface contact when both abut. .

  When the glass run 1 is attached to the sash S, as shown in FIG. 4 (b), the telescopic part 31 is contracted to move the vehicle inner side wall part 11 and the vehicle outer side wall part 12 in parallel. The contact parts 32c and 32d of the part main bodies 32a and 32b are contacted. In this state, the entire area of the facing surface 10a of the end surface of the door glass G of the base portion 10 is substantially flush, and the stretchable portion 31 is not exposed to the facing surface 10a side (inside the main body portion 13) of the end surface of the door glass G. Become. Then, the glass run 1 is fitted into the sash S while the main body 13 maintains a substantially U-shaped cross section in the non-deployed state. Therefore, when the glass run 1 is attached to the sash S, the stretchable portion 31 does not face the door glass G.

  As a result, the same effect as in the first embodiment is achieved. In addition, in the above configuration, when the telescopic portion 31 is in the contracted state, the facing surface 10a of the end surface of the door glass G of the base portion 10 is substantially flush, so that the sliding door glass G may contact the telescopic portion 31. And the stability of the sliding position and the contact position of the door glass G is ensured. As a result, the sealing performance and durability of the glass run 1 can be improved.
