Description

  The present invention relates to a structure for attaching a belt molding to a vehicle door.

  Generally, at least one clip is integrally protruded on the back surface of the belt molding, and this clip is attached to an engagement hole formed in the door panel by fitting. Conventionally, the engagement hole formed in the door panel is long in the vertical direction, and the clip has elastically deformable legs that can be elastically deformed in the vertical direction. However, if the clip is elastically deformable in the vertical direction, a vertical force is often applied to the belt molding, so that the belt molding may be inadvertently detached. Recently, depending on the door panel shape, it may be difficult to form a long engagement hole in the vertical direction, and it may be difficult to lock the belt molding by a clip that is elastically deformed in the vertical direction.

Further, when the engagement hole formed in the door panel is long in the vertical direction, in a clip having elastically deformable legs that can be elastically deformed in the vertical direction, a clearance (play) is formed between the clip and the engagement hole in the longitudinal direction of the belt molding. ), And the belt molding can move in the longitudinal direction within the clearance range. For this reason, there is a tendency that positioning in the longitudinal direction of the belt molding becomes insufficient.

That is, as shown in FIG. 3, the vehicle interior extension 21 along the vehicle interior upper edge of the panel body 12 and the vehicle exterior extension 22 along the vehicle exterior upper edge of the panel body 12 are provided. The open whole has an inverted U-shaped cross section, and has a notch 23 corresponding to the center pillar 13 at the end of the center pillar 13 side. The notch 23 is mainly formed by cutting the vehicle interior extension 21. A glass touch lip 21a slidably contacting a door glass (not shown) is integrally provided at the upper end portion of the vehicle interior extension portion 21, and a locking edge (hole) (not shown) of the front door 10 is provided at the lower end portion. A locking hook edge 21b to be locked to is integrally provided. Various shapes and materials of the belt molding 20 including the vehicle interior extension 21 and the vehicle exterior extension 22 are known, and the above is an example. Since the present invention is not related to these elements, detailed description thereof is omitted.

  The notch 23 is provided with a clip 30 that protrudes from the back surface of the belt molding 20. The clip 30 is integrated with the belt molding 20 by an end resin material (end cap) 24 that is injection-molded on the back surface of the vehicle exterior extension 22. That is, the end resin material 24 has an effect of integrating the belt molding 20 and the clip 30 and closing the back space of the vehicle outer extension 22. This end resin material 24 integrally has a cap portion 24a (FIGS. 6 and 3) located at the end of the belt molding 20.

  As shown in FIGS. 3, 5, and 6, the clip 30 includes an embedded portion 31 embedded in the end resin material 24, and an insertion portion 33 including a center fixing column 32 protruding from the embedded portion 31. have. The insertion portion 33 has a horizontally long shape in the vehicle front-rear direction corresponding to the engagement hole 15 of the door panel 11, is narrower than the width of the engagement hole 15, and is formed integrally with the distal end portion of the center fixing column 32. And a pair of front and rear widening portions (widening arms) 35 and 36 that gradually increase in width from the entrance portion 34 about the center fixed column 32 in a substantially symmetrical manner.

  One widened portion 35 of the pair of widened portions constitutes an elastic locking leg whose tip can be elastically deformed in the longitudinal direction of the belt molding 20. On the other hand, the widened portion 36 is integrated with the embedded portion 31 (center fixing column 32) and constitutes a fixed leg fixed to the end resin material 24 (belt molding 29). Neck portions 35 a and 36 a are formed on the elastic locking leg 35 and the fixed leg 36 on the boundary side with the embedded portion 31.

  The lateral width W1 of the inlet portion 34 of the insertion portion 33 is smaller than the width W2 of the engagement hole 15 in the front-rear direction, and the neck portions 35a and 36a in the free state of the elastic locking legs 35 and the fixed legs 36 (a pair of widened portions). The interval W3 (FIG. 3) is larger than the front-rear width W2 of the engagement hole 15. The insertion portion 33 can be inserted into the engagement hole 15 by elastically deforming the elastic locking leg 35. When the neck portion 35a reaches the engagement hole 15, the elastic locking leg 35 is elastically restored. The neck portion 35 a engages with one end portion of the engagement hole 15 without play, and at the same time, the neck portion 36 a of the fixed leg 36 engages with the other end portion of the engagement hole 15 without play. Of course, the maximum width when the elastic locking leg 35 and the fixed leg 36 are free and engaged with the engagement hole 15 is larger than the width W2 of the engagement hole 15.

  The clip 30 is an end clip provided at one end portion in the longitudinal direction of the belt molding 20 (a rear end portion in the case of a front door), and the elastic locking leg 35 is on the side close to the end portion of the belt molding 20. The fixed leg 36 is located on the far side. In FIG. 6, reference numeral 16 denotes an inner panel of the door panel 10, and 17 denotes reinforcement.

  In the belt molding mounting structure having the above-described configuration, the clip 30 provided integrally with the end of the belt molding 20 is inserted into the engagement hole 15 of the front door 10 (outer panel 11), whereby the belt molding 20 is mounted on the vehicle. Can be fixed to the door. That is, when the insertion portion 33 of the clip 30 is pushed into the engagement hole 15 from the inlet portion 14, the elastic locking leg 35 comes into contact with one end portion of the engagement hole 15 and elastically deforms inward, and the center fixing column 32. Are inserted while being offset with respect to the engagement hole 15. Eventually, when the neck portion 35a of the elastic locking leg 35 reaches one end portion (rear end portion) of the engagement hole 15 in the front-rear direction, the elastic locking leg 35 is elastically restored. At this time, the neck portion 36a of the fixed leg 36 also reaches the other end portion of the engagement hole 15, and the neck portions 35 and 36 are simultaneously engaged with both end portions of the engagement hole 15 without play (FIG. 5).

  In this engaged state, the neck portion 36 a of the fixed leg 36 is engaged with the front end portion (end portion on the door center side) of the engagement hole 15, and the neck portion 35 a of the elastic locking leg 35 is engaged with the engagement hole 15. Engage with the rear end. For this reason, the belt molding 20 cannot be moved forward (leftward in FIGS. 4 and 5), and the position is restricted. Further, the jaw portions 35b and 36b formed by the neck portions 35a and 36a act to prevent the clip 30 (and the molding 20) from coming out of the engagement hole 15. Since the belt molding 20 is mounted with the clip 30 attached to the engagement hole 15 while applying a tensile force to the front, and the front end is fixed to a member that supports, for example, a door mirror, the position regulation of the belt molding 20 is thus performed. If it carries out, the movement during mounting of the belt molding 20 can be prevented.

  FIG. 7 shows another embodiment of the clip 30. This embodiment corresponds to a form in which the center fixing column 32 of the above example is omitted. Similar effects can be obtained in this embodiment. In any of the embodiments, the elastic locking leg 35 of the clip 30 can be elastically deformed by the discontinuous portion (slit). Instead of forming the discontinuous portion, the clip 30 is made of a hard synthetic resin material. It is also possible to make the elastic locking leg elastically deformable (that is, fill the discontinuous portion with a soft synthetic resin material that can be easily elastically deformed). .

  Moreover, although the above embodiment is embodiment which applied this invention to the front panel door, this invention is applicable similarly to a rear panel door. FIG. 8 shows the embodiment, and the outer panel 11 of the rear panel door 10R has a panel main body portion 12 constituting a lower portion of the door window frame and a center pillar portion 13R extending upward from the front end portion thereof. Yes. The relationship between the panel main body 12 and the center pillar 13R is the same as that of the front panel door, and a press working inclined surface 14 and an engagement hole 15 are formed at the connection between the panel main body 12 and the center pillar 13R. In this embodiment, the belt molding 20 has a notch 23 corresponding to the center pillar 13R at the end on the side of the center pillar 13R, that is, the front end, and the clip 30 has its elastic engagement. The stop leg 35 is located on the side close to the end of the belt molding 20 (front), and the fixed leg 36 is located on the far side (rear). Also in this embodiment, since the fixed leg 36 is located on the side far from the end of the belt molding, the backward movement of the belt molding 20 can be suppressed. Since the belt molding 20 of the rear door 10R is mounted while applying a tensile force to the rear (right side in FIG. 8) after the clip 30 is mounted in the engagement hole 15, the rear end is fixed to the door panel with another clip, for example. In this way, when the position of the belt molding 20 is regulated, the movement of the belt molding 20 during mounting can be prevented.
