Description

  The present invention relates to a glass run and its mounting structure.

  In general, the periphery of a door glass of a vehicle such as an automobile is held by a glass run. A glass run is composed of an extrusion molding part formed in a substantially straight shape (long shape) and a molding part that connects the extrusion molding parts at a predetermined angle, for example, a door window. It consists of a front vertical side, an upper side, and a rear vertical side along the frame shape. Further, when viewed from the cross-sectional direction, the glass run has a substantially U-shaped main body portion composed of a base portion and a pair of side wall portions extending from the base portion, and a pair extending inward from the front ends of the both side wall portions to the inside of the main body portion. And a sealing lip. The glass run has a main body attached to the door sash, and the inside and outside of the door glass are sealed by the pair of seal lips.

  As materials constituting the glass run, ethylene-α-olefin non-conjugated diene copolymer (EPDM), olefin-based thermoplastic elastomer (TPO), and the like are known.

By the way, the shear stress resulting from the opening and closing of the door glass may act on the glass run, and in this case, there is a concern that the glass run may shift in the longitudinal direction. Therefore, as a technique for preventing the shift movement, it is known to provide a locking piece for movement prevention in the mold part. This locking piece is brought into contact with and locked to the edge of the door sash, so that the shift movement of the glass run is regulated (for example, see Patent Document 1).
JP 2000-158950 A

  However, according to Patent Document 1, the locking piece protrudes in the vicinity of the connection end portion with the extrusion molding portion in the mold forming portion. Therefore, the door sash exists only up to the connection portion between the mold forming portion and the extrusion forming portion, and the door sash does not exist in the most part corresponding to the mold forming portion. Therefore, even if it is possible to regulate the shift movement in the locking direction by the locking piece, it is not possible to control the shift movement in the mold forming part in a direction different from the locking, and the mold forming part itself is deformed. It is feared that they will be equal.

  In addition, in the case of a general glass run having no locking piece, the corner portion (corner portion) is first fitted into the corner portion of the door sash before mounting, and then in the vertical direction and the front-rear direction. The procedure of fitting along is taken. However, as described above, when the locking piece is provided at a position away from the so-called corner portion, the locking piece is brought into contact with and locked to the edge of the door sash separately from the fitting of the door sash. Work is also required. For this reason, the operator must pay attention not only to fitting the molded part into the sash but also to positioning (locking) the locking piece, which may cause a significant deterioration in work efficiency.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to effectively prevent displacement movement due to opening and closing of the door glass, and to dramatically improve the assembling workability. Another object is to provide a glass run and its mounting structure.

And a rear sash DS3 provided corresponding to the rear side (right side in FIG. 2) of the DF. With respect to the front sash DS2 and the rear sash DS3, the upper ends thereof extend as far as possible to the upper edge corner portions C1 and C2 of the door glass window portion W. On the other hand, a relatively wide gap is provided between each end portion of the upper sash DS1 and the upper edge corner portions C1 and C2.

  The glass run 1 is made of, for example, TPO, as viewed in the longitudinal direction, the extrusion molding portion 2 corresponding to the upper side portion, the extrusion molding portions 3 and 4 corresponding to the front and rear vertical side portions, and the extrusion molding portions 2, 3 and 3. A distinction is made between the mold forming parts 5 and 6 that connect the four end parts. Each of the extrusion molding portions 2 to 4 is formed in a substantially linear shape (in a long shape) by an extrusion molding machine (not shown). In this embodiment, the extrusion molding portion 2 is the upper extrusion molding portion and the extrusion molding portion 3 is the front. The extrusion molding section 4 corresponds to the longitudinal extrusion molding section, and the extrusion molding section 4 corresponds to the rear longitudinal extrusion molding section. The mold forming parts 5 and 6 are connected and molded by a mold apparatus (not shown) so that the two extruded parts 2, 3 and 2, 4 are connected to each other at a predetermined angle. In the present embodiment, the mold forming portion 5 corresponds to the front mold forming portion, and the mold forming portion 6 corresponds to the rear mold forming portion.

  The mold forming portion 6 includes a vertical piece portion 21 as a second piece portion extending in the vertical direction, and a first piece portion extending from the upper end of the vertical piece portion 21 so as to be substantially orthogonal to the vertical piece portion 21. The upper piece portion 31 is substantially L-shaped as a whole. The vertical piece 21 is connected to the extrusion part 4, and the upper piece 22 is connected to the extrusion part 2.

  The mold forming part 5 is also composed of a vertical piece part and an upper piece part in the same manner as the mold forming part 6.

  The glass run 1 of this embodiment is attached to the sash DS. More specifically, the extrusion molding part 2 corresponds to the upper sash DS1, the extrusion molding part 3 corresponds to the front sash DS2, and the extrusion molding part 4 corresponds to the rear sash DS3.

  3 is a cross-sectional view taken along line JJ of FIG. As shown in the figure, the extruded portion 2 corresponding to the upper side portion includes a main body portion 11 and a pair of seal lips 12 and 13. The main body 11 includes a base portion 14 fitted into the sash DS, a vehicle outer side wall portion 15 and a vehicle inner side wall portion 16 extending from the base portion 14. Further, the seal lips 12 and 13 extend from substantially the front ends of the both side wall portions 15 and 16 toward the inside of the main body 11 (in the direction of the base portion 14), respectively, and thereby the vehicle outer side and the vehicle inner side of the door glass respectively. It is designed to be sealed. Further, in the present embodiment, the vehicle exterior design lip 17 that extends outward (vehicle exterior) from the vehicle exterior side wall 15 and the vehicle interior design that extends outward (vehicle interior) from the vehicle interior side wall 16. A lip 18 is formed. The extrusion molding parts 3 and 4 and the mold molding parts 5 and 6 also have a main body part and a pair of seal lips, and have the same configuration as before.

  In the present embodiment, the mold forming portion 6 is provided with a locking protrusion 31 as a protrusion protruding toward the sash DS3. More specifically, as shown in FIG. 4, the locking projection 31 is formed at the corner (corner) at the boundary between the vertical piece 21 and the upper piece 22 from the vertical piece 21 to the rear sash DS3 side. The projection is formed so as to be substantially orthogonal to the longitudinal direction of the vertical piece 21. The locking projection 31 is substantially in contact with the upper end of the rear sash DS3 when the glass run 1 is attached to the sash DS. Thereby, the locking projection 31 is locked to the upper end of the rear sash DS3, and the downward movement of the locking projection 31 is restricted.

  Next, assembly of the glass run 1 to the sash DS will be described with reference to the drawings.

  First, as shown in FIG. 1, the mold forming part 6 of the glass run 1 is attached so that the upper edge corner part C2 of the door DF and the mold forming part 6 are made to correspond to each other. That is, the corner portion of the mold forming portion 6 is fitted into the upper edge corner portion C2 in an obliquely upward direction (the arrow direction in FIG. 1). Here, in this embodiment, since the latching protrusion part 31 protrudes from the said corner part, the latching protrusion part 31 will be pushed in right above the upper end part of the door sash DS3 with the said fitting. . And the lower end part of the latching protrusion part 31 is made into the state which substantially contact | abutted with the upper end part of the door sash DS3. As a result, the molded portion 6 of the glass run 1 is attached and held around the corner portion, and the locking projection 31 is locked by the rear sash DS3 (see FIG. 4).

  Next, the mold forming part 5 is moved toward the upper edge corner part C1 of the door DF, and the mold forming part 5 is fitted into the upper edge corner part C1. Thereby, the glass run 1 is held in the mold forming part 5.

  Thereafter, the extrusion molding parts 2, 3, 4 are pressed so as to trace from the inner peripheral side, and the extrusion molding parts 2, 3, 4 are fitted into the sash DS, whereby the attachment of the glass run 1 is completed.

  As described above, the mold forming portion 6 is provided with the locking protrusion 31 that can be locked to the upper end portion of the rear sash DS3. Therefore, the rear sash DS3 restricts the downward movement of the molding part 6. Therefore, when the door glass is opened and closed, even if a downward shift stress acts on the mold forming portion 6, it is possible to suppress a situation in which the glass run 1 is displaced.

  Further, since the locking projection 31 is provided at the corner portion (corner portion between the vertical piece portion 21 and the upper piece portion 22; corner portion) of the mold forming portion 6, the rear sash DS3 is disposed on the mold forming portion 6. The corner portion (upper edge corner portion C2) can be extended to the limit. Therefore, it is possible to stably hold the mold forming part 6 and to prevent the mold forming part 6 itself from being deformed or the like due to a displacement stress acting on the mold forming part 6. As a result, the displacement of the glass run 1 can be effectively suppressed.

  In addition, it is possible to substantially match the portion where the mold forming part 6 is fitted into the sash DS (the fitting direction) and the portion where the locking projection 31 is locked to the end of the rear sash DS3 (the pushing direction). Therefore, the fitting of the corner portion of the mold forming portion 6 and the pushing of the locking projection portion 31 can be performed at a time, and the work efficiency can be significantly improved with respect to the assembly of the glass run 1 to the sash DS.

  Further, in the present embodiment, when the molding portion 6 is securely fitted, the pushing of the locking projection 31 is completed, so that the locking projection 31 is locked. It is not necessary to check each time whether or not it is surely performed.

  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 locking projection 31 protrudes in a direction substantially perpendicular to the longitudinal direction of the vertical piece portion 21, but is not necessarily limited to such a configuration, and the locking projection 31. However, what is necessary is just to be comprised in the corner part of the boundary of the vertical piece part 21 and the upper piece part 22 so that it may protrude in the back sash DS3 side. For example, as shown in FIG. 5, it is good also as a structure that the latching protrusion part 31 protrudes in the assembly | attachment direction (diagonally upward) to the upper edge corner part C2 of the shaping | molding part 6. FIG.

  (B) Although not particularly mentioned in the above embodiment, the mold forming portion 5 may be configured to be provided with a locking projection. For example, as shown in FIG. 5, a locking projection 32 that protrudes from the upper side of the mold forming portion 5 toward the upper sash DS1 is provided, and the front end portion of the upper sash DS1 when the glass run 1 is assembled to the sash DS. You may comprise so that it may be in a substantially contact state. In that case, the displacement movement in the longitudinal direction of the glass run 1 can be more reliably regulated.

  (C) The locking projection 31 may be formed integrally with the mold forming portion 6. Alternatively, the locking protrusion 31 may be formed separately from the mold forming portion 6. A part of it may be embedded.
