Description

  The present invention relates to a belt molding that is mounted along an upper edge of a door panel of a vehicle door and seals between the door panel and a window plate (side window glass).

  In general, a belt molding is configured by joining and integrating a synthetic resin lip or the like with a metal core. In the belt molding, many designs are employed in which a part of the surface of the metal core material is intentionally exposed and the exposed surface is used as a design surface having a metallic appearance. In addition, when the belt molding is attached to the upper edge of the door panel, the belt molding end region is set to prevent the belt molding end from interfering with a part of the vehicle body (for example, garnish constituting the door window frame). A design in which a part of the cutout is formed is also employed, and in that case, a covering material called an “end cap” for covering the cutout portion (defect portion) is also mounted. That is, one type of belt molding is known that is composed of a long belt molding main body and an end cap that is attached to the end region of the belt molding main body.

  Incidentally, there is an attempt to integrally mold the end cap by injection molding with the belt molding body as an insert. However, if the belt molding body (especially the core material) is made of metal, the metal insert slips in the injection mold (mold), and the belt molding body can be correctly set in a predetermined position in the mold. Or a resin end cap may not be sufficiently bonded to the metal belt molding body. For this reason, it is customary to separate the belt molding body and the end cap.

  The end cap generally includes a clip piece for attaching the belt molding to the vehicle body (door panel) and a covering portion for covering the cutout portion (defect portion) of the belt molding, which makes the shape complicated. easy. For this reason, when it is going to manufacture an end cap as a one-piece | unit (single article) by injection molding, it faces difficult problems, such as complication of the structure of a shaping | molding die and ensuring of the openability of a shaping | molding die. Therefore, instead of giving up forming the end cap as a single piece from the beginning, a design method has been proposed in which the base (or base) and the lid are divided into two pieces, which are individually injection molded and then combined. .

  Patent document 1 shows the prior example of such a two-piece type end cap. According to paragraph 0018 of Patent Document 1, a synthetic resin clip body (end cap) 1 is composed of a base 11, a clip piece 12 projecting from the base 11, and the base 11 and the clip piece 12. The lid 14 is made up of. According to paragraph 0022 of the same document, the base 11 is inserted into the molding body 5 and the lid 14 is fitted to the end 5a of the molding body, and then a given caulking piece is bent to form the lid. The lid body 14 and the base portion 11 (and the clip piece 12 integral with the base portion 11) are fixed to the molding body 5 by press-contacting the caulking receiving portions provided at the corresponding portions of the base portion 11 and the base portion 11.

JP 2011-245959 A

  However, since the clip body (end cap) 1 of Patent Document 1 does not have a structure that holds the relative positional relationship between the base portion 11 and the lid body 14 deterministically or fixedly, the base portion 11 and the lid body 14 are respectively attached. When caulking (caulking) the molding body 5, the respective fixing positions may be slightly shifted. That is, the dimension (or relative arrangement) between the lid body 14 and the clip piece 12 integrated with the base portion 11 varies, and when the molding is attached to the vehicle body with the clip piece 12, the end position ( In other words, the lid 14 has a variation in position). As a result, a gap having a size that cannot be ignored is generated between the lid body 14 and the base portion 11, and the appearance may deteriorate.

  An object of the present invention is to provide a belt molding having a two-piece type end cap comprising a base body and a lid body, by deterministically or securely holding the relative arrangement relationship between the base body and the lid body of the end cap, thereby An object of the present invention is to provide a belt molding capable of attaching an end cap to a belt molding main body without causing the bodies to be displaced from each other.

  Hereinafter, a belt molding according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows a front door of a general four-door passenger vehicle. The front door 1 is disposed between a door panel 2, a window frame 3 extending from a front upper end of the door panel 2 to a vehicle roof (not shown), and a rear end portion of the window frame 3 and a rear upper end of the door panel 2. The garnish 4 extends substantially vertically, and the window plate (side window glass) 5 is provided between the door panel 2 and the window frame 3 so as to be movable up and down. The belt molding 6 of the present embodiment is a sealing material that is attached substantially horizontally along the upper edge of the door panel 2 and also serves as a decoration for sealing between the door panel 2 and the window plate 5.

  FIG. 2 shows a (rear) end region of the belt molding 6 surrounded by a two-dot chain circle in FIG. As can be seen from FIGS. 1 and 2, the belt molding 6 includes a long belt molding main body 7 extending along the upper edge of the door panel 2 and an end cap 8 attached to a rear end region of the belt molding main body 7. And.

  As shown in the cross-sectional view of FIG. 3 (and FIG. 4), the belt molding body 7 includes a metal core 11 and a resin bonded to the outer surface and a part of the inner surface of the core 11 by extrusion molding. It is a dissimilar material composite provided with manufactured lips and the like (15a to 15f). The core material 11 shown in FIGS. 3 and 4 has a cross section, but is not provided with hatching in order to avoid difficulty in viewing due to the complexity of the lines.

  As shown in FIG. 3, the metal core 11 includes a vehicle interior side wall portion 12 and a vehicle exterior side wall portion 13 that face each other, and a top wall that integrally connects these side wall portions 12 and 13 at their top portions. The vehicle interior side wall portion 12, the top wall portion 14, and the vehicle exterior side wall portion 13 form a cross section that is convex upward and concave downward. A part of the surface of the core material 11 (for example, the outer surface of the top wall portion 14 or the outer surface of the vehicle outer side wall portion 13 in FIG. 3) is used as a decorative surface that exposes the metal background and improves the appearance of the belt molding. . The metal constituting the core member 11 is preferably stainless steel, but other metals such as aluminum may be used instead.

  The surface of the inner side wall portion 12 of the core material of the belt molding body 7 is generally covered with a resin 15, and the upper side lip 15 a, the inner side lip 15 b and the first lip 15 b made of the same resin are formed on the surface of the inner side wall portion 12. A lower engaging portion 15c is provided. Further, the same resin-made holding lip 15d, second lower engaging portion 15e, and vehicle outer lip 15f are provided on the inner surface of the vehicle outer side wall portion 13 of the core material. The upper lip 15a and the vehicle inner lip 15b seal a gap formed between the window plate 5 and prevent rainwater and dust from entering the vehicle interior and the door panel 2. The first lower engagement portion 15c, the holding lip 15d, the second lower engagement portion 15e, and the vehicle outer lip 15f are engagement portions for holding and fixing the belt molding body 7 to the upper edge of the door panel 2. It is. The resin bonded to the core material 11 is preferably an olefin-based thermoplastic elastomer, but the lips and the like (15a to 15f) bonded to the core material 11 may be formed of an elastically deformable material. Other types of thermoplastic elastomers (for example, styrenic thermoplastic elastomers), soft polyvinyl chloride or rubber may be substituted.

  The belt molding body 7 does not have a uniform cross-sectional shape over the entire longitudinal direction thereof, but has a defect portion 16 to which the end cap 8 is attached in the rear end region (FIG. 8 ( B)). As can be seen from FIG. 8 (B), in the missing part 16, a part of the three wall parts (12, 13, 14) constituting the belt molding body 7 is notched, and more specifically, the top wall. The part 14 and the vehicle interior side wall part 12 are cut out so as to be removed. As a result, the defect part 16 is formed only in the vehicle outer side wall part 13 and a part of the top wall part 14 connected thereto. It is configured to leave. By setting such a missing portion 16 in the end region of the belt molding body 7, it is possible to avoid a situation in which the end portion of the belt molding body 7 interferes with the garnish 4 erected on the door panel 2. However, if the defect portion 16 is left in a notched state, burrs and deformations of the notched portion are exposed, resulting in deterioration of the appearance and danger at the time of contact. The end cap 8 is attached.

[end cap]
As shown in FIG. 8A, the end cap 8 of this embodiment includes a base body 20 and a lid body 30, which are individually injection-molded as separate parts. The resin constituting the substrate 20 and the lid 30 is preferably polybutylene terephthalate (PBT), but instead of this, polypropylene (PP), polyacetal (POM), polyamide (PA), polyphenylene sulfide (PPS). ), Or a thermoplastic resin such as polyetheretherketone (PEEK).

[End cap substrate]
As shown in FIGS. 2, 5, and 8A and 8B, the base 20 of the end cap has a long plate-like base body 21 extending in the longitudinal direction of the belt molding. The base body portion 21 has a covering portion 22 extending over almost the entire length of the base body 20, and the covering portion 22 extends along the upper edge of the base body 20 so as to cover the upper portion of the defect portion 16 of the belt molding body. And it is formed so that it may protrude toward the vehicle outer side. Further, as shown in FIG. 5, in the vicinity of the lid-side end portion of the base body portion 21, a cantilever-shaped rod-shaped portion 23 positioned directly below the covering portion 22, and the lid-side end portion of the rod-shaped portion 23. A regulating convex portion 25 located below is provided.

  The cantilever-shaped rod-shaped portion 23 is located directly below the covering portion 22 and extends along the longitudinal direction of the belt molding. Here, the “cantilever shape” represents that the rod-like portion 23 is partially separated from the base body portion 21 with a short gap S (FIG. 5) immediately below it interposed therebetween. ing. Since the rod-like portion 23 has such a cantilever shape, the vicinity of the tip portion (end portion on the lid side) of the rod-like portion 23 is a free end or an elastic end capable of some elastic deformation. A convex base locking portion 24 is formed at the tip of the cantilever-shaped rod-shaped portion 23. The base locking portion 24 engages with a part of the lid 30 (projection 33) described later to prevent the lid 30 from being detached from the base 20 when the base is mounted.

  As shown in FIG. 5, the restriction convex portion 25 is formed as a substantially hexahedral block body that protrudes from the base body portion 21 toward the vehicle outer side at the lid body side end position of the base body portion 21. The restricting convex portion 25 has an upper surface 25a, a lower surface 25b, a terminal side surface 25c, a center side surface 25d (a surface opposite to the terminal side surface 25c), a vehicle outer end surface 25e, and a position lower than the vehicle outer end surface. It has a stepped portion end face 25f located at a deep position on the inner side of the vehicle. The plurality of surfaces are involved in the unique positioning of the lid body 30 with respect to the base body 20 based on the mutual contact relationship with the lid body 30 as will be described later. More specifically, the upper surface 25a and the lower surface 25b are involved in the vertical positioning of the lid 30 with respect to the base body 20 as an upper restricting portion and a lower restricting portion, respectively. Further, the end side surface 25c and the center side surface 25d are involved in positioning in the longitudinal direction of the lid body 30 with respect to the base body 20 as a terminal side restricting portion and a center side restricting portion, respectively. Furthermore, the vehicle outer end surface 25e and the stepped portion end surface 25f are partly involved in the positioning of the lid 30 with respect to the base body 20 in the vehicle interior / exterior direction.

  As shown in FIG. 8, the base body 21 is provided with a clip piece 26 on the side surface on the vehicle inner side. The door panel 2 is provided with a clip stopper (not shown) corresponding to the clip piece 26, and the belt molding 6 is attached to the door panel 2 by engaging the clip piece 26 with the clip stopper.

  6 is a schematic side view for explanation as viewed from the direction of arrow A in FIG. As shown in FIG. 6, the projecting direction of the cover portion 22 toward the vehicle outer side (shown by a broken line L1) and the projecting direction of the restricting convex portion 25 toward the vehicle outer side (shown by a broken line L2) inject the base body 20. Both parts (22, 25) are designed so as to be substantially parallel to the mold releasing direction of the mold used for molding. According to this design, it becomes easy to manufacture the base body 20 having a complicated shape as described here by injection molding. In addition, the dashed-two dotted line P in FIG. 6 shows the parting line of a shaping | molding die.

[End cap lid]
As shown in FIG. 4, FIG. 5, FIG. 7 and FIG. 8A, the end cap lid 30 has a lid body 31 for covering the end surface of the belt molding body 7. Further, the lid body portion 31 is provided with a cover portion 32, a projection portion 33, and an attachment portion 34. The protrusion 33 functions as a lid locking portion.

  As shown in FIGS. 4 and 5, the cover portion 32 is positioned vertically on the outer edge (upper side and outer edge of the vehicle) of the lid body portion 31 to cover the outer peripheral edge position of the end surface of the belt molding body 7. This is a strip-shaped part. The longitudinal strip-shaped outer peripheral surface of the cover portion 32 constitutes a decorative surface of the belt molding together with the outer surface of the outer side wall portion 13 and the top wall portion 14 of the core material of the belt molding main body 7. On the other hand, the projecting portion 33 is an engaging portion (lid body locking portion) provided at a position closer to the vehicle inner side of the upper end of the lid body portion 31 and engages with the base body locking portion 24 of the base body portion 21. This prevents the lid 30 from being detached from the substrate 20 when the substrate is mounted.

  The attachment portion 34 is a convex portion protruding from the lid body portion 31 toward the base body portion 21 on the side of the lid body portion 31 facing the base body portion 21. The attachment portion 34 is provided with a regulation recess 35 that opens toward the vehicle interior side. The restricting recess 35 can accommodate the restricting convex portion 25 of the base body, and the inner wall portion of the restricting recessed portion 35 can come into contact with the upper surface 25a, the lower surface 25b, the distal side surface 25c and the central side surface 25d of the restricting convex portion 25. It is formed to be. Specifically, as shown in FIG. 7, the inner wall portion of the restriction concave portion 35 includes an inner wall upper surface 35 a corresponding to the upper surface 25 a of the restriction convex portion, an inner wall lower surface 35 b corresponding to the lower surface 25 b of the restriction convex portion, and a restriction convex portion. An inner wall end side surface 35c corresponding to the end side surface 25c and an inner wall center side surface 35d corresponding to the center side surface 25d of the restricting convex portion are formed. Further, a back bottom surface 35 e is formed in the back of the regulation recess 35. Thus, in the present embodiment, the restriction convex portion 25 of the base body and the restriction concave portion 35 of the lid can be fitted to each other.

[Operation and Effect of Embodiment]
The belt molding of this embodiment is assembled in the procedure as shown in FIGS.
First, the end cap 8 is assembled by attaching the lid 30 to the end portion of the base 20 of the end cap. Specifically, as shown in FIG. 5 and FIG. 8A, the restriction recess 35 of the mounting portion 34 of the lid 30 is fitted into the restriction recess 35 of the base body 20 so that the restriction recess 35 of the base body 20 is fitted. The convex part 25 is inserted.

  In the process of bringing the lid 30 close to the base body 20 so as to insert the regulating convex part 25 into the regulating concave part 35, the projection 33 of the lid gets over the base locking part 24 and engages with the base locking part 24 ( (See FIG. 4). This engagement prevents the lid 30 from being detached from the base body 20. Almost simultaneously with the completion of the engagement between the protrusion 33 and the base locking portion 24, as shown in FIG. 4, the vehicle outer end surface 25e of the restricting convex portion comes into contact with the back bottom surface 35e of the restricting concave portion, and the step of the restricting convex portion. The part end face 25f abuts on a regulating recess lower side wall portion 36 (see FIG. 7) that defines and forms the lower side of the regulating recess 35. The movement (relative displacement) of the lid 30 toward the vehicle inner side with respect to the base body 20 is restricted by the contact between the vehicle outer end surface 25e and the back bottom surface 35e and the contact between the stepped portion end surface 25f and the restriction recessed lower wall portion 36. Is done. On the other hand, the movement (relative displacement) of the lid 30 to the vehicle outer side with respect to the base 20 is restricted by the mutual engagement of the protrusion 33 as the lid locking portion and the base locking portion 24.

  In addition, the fitting of the restricting convex portion 25 of the base and the restricting concave portion 35 of the lid is completed almost simultaneously with the completion of the engagement between the protrusion 33 and the base engaging portion 24. In a state in which the restriction convex portion 25 is fitted in the restriction concave portion 35, the four surfaces (25a to 25d) of the restriction convex portion 25 abut on the four inner wall surfaces (35a to 35d) of the restriction concave portion 35, respectively. In other words, the upper surface 25a and the lower surface 25b of the restricting convex portion abut on the inner wall upper surface 35a and the inner wall lower surface 35b of the restricting concave portion, respectively. Based on this vertical contact relationship, the vertical movement of the lid 30 relative to the base body 20 is restricted. Further, the terminal side surface 25c and the central side surface 25d of the restricting convex part come into contact with the inner wall terminal side surface 35c and the inner wall central side surface 35d of the restricting concave part, respectively. Based on the front-rear (FIG. 5) contact relationship, the front-rear movement (longitudinal movement) of the lid 30 with respect to the base body 20 is restricted. In this manner, the base 20 and the lid 30 can be firmly fixed to each other by fitting the regulation convex portion 25 of the base and the regulation concave 35 of the lid.

  Next, as shown in FIG. 8B, the assembled end cap 8 is inserted into the end portion (defect portion 16) of the belt molding body 7, and the end cap 8 is bonded to the belt molding body 7 with an adhesive. And fix. As a result, the missing part 16 is covered with the end cap 8. Thereafter, the belt molding 6 can be attached to the door panel 2 by engaging the clip piece 26 of the end cap 8 with the clip stopper of the door panel 2.

  According to the belt molding 6 of the present embodiment, the covering portion 22 of the base 20 of the end cap 8 covers the upper portion of the defective portion 16 of the belt molding main body 7, and the lid body of the lid 30 of the end cap 8. By covering the end surface of the belt molding body 7 and the outer peripheral edge position of the end surface with the portion 31 and the covering portion 32, the appearance of the end region of the belt molding body 7 can be improved. Further, in the present embodiment, as described above, the fitting relationship between the restriction convex portion 25 of the base body 20 and the restriction concave portion 35 of the lid body 30, and the base body locking portion 24 of the base body 20 and the lid body latching of the lid body 30. Based on the engagement relationship of the portion (projection portion 33), the vertical movement, forward / backward movement (longitudinal movement) and inward / outward movement (relative displacement to the vehicle interior and vehicle exterior) of the lid body 30 with respect to the base body 20 are effective. Can be regulated. Therefore, even though the end cap 8 employs a two-piece structure including the base body 20 and the lid body 30, the base body 20 and the lid body 30 are prevented from being displaced from each other or rattled. And the relative arrangement relationship between the lid 30 and the lid 30 can be held deterministically or fixedly. Therefore, even when the belt molding 6 is attached to the door panel 2, it is possible to prevent a gap having a size that cannot be ignored between the covered portion 22 of the base body 20 and the covering portion 32 of the lid 30 from occurring. The appearance (appearance) of the end region 6 can be kept good.

[Other Embodiments]
The restriction convex part of the base body and the restriction concave part of the lid body in the end cap according to the present invention are not limited to the restriction convex part 25 (FIG. 5) and the restriction concave part 35 (FIG. 7) as described above. As long as the purpose is followed, the design can be changed as appropriate. For example, the shape shown in FIGS. 9 and 10 may be used.

  The restriction convex portion 125 shown in FIG. 9 is formed as a polyhedral block body projecting in a “convex” shape from the base body portion 21 toward the outside of the vehicle. Like the restricting convex portion 25 in FIG. 5, the restricting convex portion 125 has an upper surface 125a, a lower surface 125b, a terminal side surface 125c, a central side surface 125d, a vehicle outer end surface 125e, and a position lower than the vehicle outer end surface 125e. In addition, it has a stepped end face 125f located at the back of the vehicle interior. The roles of these surfaces 125a to 125f are the same as the roles of the corresponding surfaces 25a to 25f of the restricting convex portion 25 in FIG. Further, the regulating convex portion 125 is formed with a step surface 125g that intersects with the vehicle outer end surface 125e.

  FIGS. 9 and 10 show a lid 130 having a regulation recess 135 corresponding to the regulation projection 125 of FIG. 9 and 10 has the same basic structure as the lid 30 of FIGS. 5 and 7, but the shapes of the attachment portion 134 and the regulation recess 135 are slightly different from those of the lid 30. . That is, as shown in FIG. 9 and FIG. 10, the lid body 130 has an attachment portion 134 that defines a regulation recess 135 into which the regulation projection 125 of FIG. 9 can be fitted. The inner wall portion of the restriction recess 135 includes an inner wall upper surface 135a corresponding to the upper surface 125a of the restriction protrusion, an inner wall lower surface 135b corresponding to the lower surface 125b of the restriction protrusion, and an inner wall corresponding to the terminal side surface 125c of the restriction protrusion. An inner wall central side surface 135d corresponding to the terminal side surface 135c and the central side surface 125d of the restricting convex portion is formed. A step-shaped back bottom surface 135e is formed in the back of the regulation recess 135. Furthermore, an inner wall step surface 135 g corresponding to the step surface 125 g of the restriction convex portion 125 is formed on the inner wall portion of the restriction concave portion 135. The roles of the surfaces 135a to 135e of the restricting recess 135 are the same as the roles of the corresponding surfaces 35a to 35e of the restricting recess 35 in FIG. And it is the same as that of embodiment of FIGS. 1-8 that the relative arrangement | positioning relationship of the base | substrate 20 and the cover body 130 can be hold | maintained definitely or fixedly by making the control convex part 125 and the control recessed part 135 fit. is there. 9 and 10, the vertical movement of the lid body 130 with respect to the base body 20 is also restricted by the contact between the step surface 125g of the restriction convex portion 125 and the inner wall step surface 135g of the restriction concave portion 135. The

  In the embodiment of FIGS. 1 to 8 and the embodiment of FIGS. 9 and 10, the base locking portion 24 located at the tip of the rod-like portion 23 of the base 20 is engaged with the protrusion 33 of the lid (30, 130). Thus, a detachment preventing structure for preventing the lid from detaching from the base body 20 is constructed, but this detachment preventing structure can be replaced with a structure as shown in FIGS. Specifically, instead of forming the projection 33 on the lid, as shown in FIGS. 11 (B1) and 11 (B2), the lid locking portion is provided on the upper end surface of the attachment portion 134 of the lid 130. 137 is projected. On the other hand, instead of forming the base locking portion 24 at the tip of the rod-shaped portion 23 of the base body 20, the cantilever-shaped rod-shaped portion 23 itself engages with the lid locking portion 137. It uses as a part (23) (refer FIG. 11 (A1) and (A2)). In addition, in order to make it easy to attach the cover body 130, the edge part of the rod-shaped part 23 of FIG. 11 (A1) and (A2) has a part taper shape. According to this structure for preventing detachment, when the restricting convex portion 125 of the base body 20 is fitted into the restricting concave portion 135 of the lid body 130, as shown in FIG. The stoppers 137 engage with each other, and the mutual engagement restricts the movement (relative displacement) of the lid body 130 relative to the base body 20 to the vehicle exterior side. Further, in the embodiment shown in FIGS. 11 and 12, the rod-like portion 23 serving as the base engaging portion is displaced upward to engage the rod-like portion 23 and the lid engaging portion 137. Can be bent. For this reason, it is preferable that the lid locking portion 137 can be easily formed in a desired size, and the lid locking portion 137 and the rod-like portion 23 can be stably engaged. 12 corresponds to a cross section taken along the line BB in FIG.
