Description

  The present invention relates to an attachment structure for a long molding attached to a door waist portion of a vehicle.

As a mounting structure for attaching a long molding to the vehicle's door waist, an engagement protrusion is formed on the resin end cap attached to the end of the molding, while a locking hole is formed in the mounting flange of the door waist Then, in a state where the end cap is attached to the molding, it is known that the molding is fixed to the door waist portion by fitting the engaging projection of the end cap into the locking hole of the mounting flange.
Utility Model Registration No. 2593725

  However, in this conventional molding mounting structure, when the molding is attached to the mounting flange from above, the engagement projection of the end cap bends, and when the engagement projection comes to the locking hole position, the shape is restored and engaged. Since the engagement protrusion is once engaged with the locking hole, it is difficult to remove the end cap from the mounting flange unless the engagement protrusion is pushed back by a hand or a tool. For this reason, when the end portion of the molding is arranged in a narrow space where a hand or a tool cannot be inserted, it is necessary to pull the molding and release the engagement between the end cap and the mounting flange during maintenance. However, there is a concern that the mall may be damaged when the mall is pulled forcibly.

  Therefore, the present invention is intended to provide a molding mounting structure in which the end of the molding can be easily detached from the mounted member on the vehicle body side together with the end cap without causing damage to the end cap.

The invention according to claim 1, which solves the above problem, is provided with an end cap (for example, an end cap 10 in an embodiment described later) at an end of a long molding (for example, a waist molding 2 in an embodiment described later). A mounting structure of a molding for mounting and mounting the molding to a mounted member (for example, a flange 3a in an embodiment described later) via the end cap, and an engagement protrusion (for example, described later) While the engagement protrusion 31 in the embodiment is provided, a locking hole (for example, a locking hole 38 in the embodiment described later) for engaging the engagement protrusion is formed in the mounted member. From the mounted member toward the other end portion side of the molding, with the engagement protrusion of the end cap attached to the one end portion being engaged with the locking hole. Tapered surface inclined in a direction contrary (e.g., a tapered surface 36 in the embodiment), characterized in that the formation of the.
When removing one end portion of the molding attached to the mounted member on the vehicle body side from the mounted member together with the end cap, the end cap on one end side is pulled toward the other end side through the molding. Thus, when the end cap is pulled toward the other end, the taper surface of the engagement protrusion slides on the edge of the engagement hole, and the engagement between the engagement protrusion and the engagement hole is gradually released.

According to a second aspect of the present invention, there is provided the molding mounting structure according to the first aspect, wherein the engaging protrusion is formed of a claw-like piece that can be elastically bent and deformed at a base portion side.
When removing the molding from the mounted member, if the end cap is pulled toward the other end, the taper surface on the engaging protrusion slides on the edge of the locking hole, and the base side of the engaging protrusion is elastic. Bends and deforms.

According to a third aspect of the present invention, there is provided the molding mounting structure according to the first or second aspect, wherein the engaging projection is formed on the inner wall of the locking hole in a state where the molding is attached to the mounted member. A displacement regulating surface that abuts along the longitudinal direction of the molding (for example, a displacement regulating surface 37 in an embodiment described later) is provided, and the tapered surface is adjacent to the other end of the molding of the displacement regulating surface. It is provided.
As a result, in a state where the molding is attached to the mounted member, the displacement restricting surface of the engaging projection comes into contact with the inner wall of the locking hole along the longitudinal direction of the molding and is in a direction substantially orthogonal to the longitudinal direction of the molding. Displacement is regulated.

According to a fourth aspect of the present invention, in the molding mounting structure according to any one of the first to third aspects, the tapered surface is formed only on an end cap on one end side of the molding. And
Thereby, even if the end cap on the other end side of the molding is pulled in the longitudinal direction of the molding, it is difficult to come off from the mounted member.

  According to the first aspect of the present invention, when the end cap on one end side is pulled toward the other end side through the molding, the taper surface provided on the engagement protrusion is on the edge of the locking hole. Because the sliding engagement and the engagement hole are easily released, the end of the molding can be easily removed from the mounted member on the vehicle body together with the end cap without causing damage to the end cap. Can

  According to the second aspect of the present invention, since the engaging projection is constituted by a claw-like piece that can be elastically deformed at the base portion side, the end cap is pulled toward the other end of the molding. In this case, the engagement between the engaging projection and the locking hole can be released more easily.

  According to the third aspect of the present invention, the displacement restricting surface of the engaging protrusion abuts the inner wall of the locking hole along the longitudinal direction of the molding, thereby restricting displacement in a direction substantially orthogonal to the longitudinal direction of the molding. Therefore, it is possible to stably hold the end cap and the end portion of the molding in a state where the molding is in contact with the mounted member.

  According to the invention described in claim 4, since the tapered surface is formed only on the end cap on one end side of the molding, the holding strength of the entire molding in a state where the molding is attached to the mounted member can be increased. .

Is formed. Moreover, the top part of the engagement protrusion 31 is formed in a flat shape, and the top part surface constitutes a displacement restricting surface 37 described later.

  On the other hand, a substantially rectangular locking hole 38 is formed in the vicinity of the end of the flange 3a of the door outer panel 3 on the vehicle body front side. When the end cap 10 is attached to the waist molding 2 from the upper side with the end cap 10 attached to the waist molding 2, the engagement hole 38 is fitted to the engagement protrusion 31 of the end cap 10 from the outside of the vehicle. It has become. At this time, the displacement restricting surface 37 at the top of the engaging protrusion 31 is in contact with the inner surface on the upper side of the locking hole 38 along the longitudinal direction of the molding.

  As shown in FIG. 1, the periphery of the front sash coupling portion of the door body 5 has a narrow bag-like structure, and it is impossible to detach the end cap 10 from the inner panel 4 side. On the other hand, the periphery of the sash coupling portion on the rear side of the door body 5 has a relatively wide hollow structure, so that the end cap 11 can be attached and detached through the opening 41 provided in the door inner panel 4. Yes.

  Actually, when the waist molding 2 is attached to the flange 3a of the door outer panel 3, the end caps 10 and 11 are fitted and fixed to the front and rear ends of the waist molding 2 in advance, and the cross section of the waist molding 2 is substantially U-shaped. The shaped portion is engaged with the flange 3a from above.

  At this time, in the end cap 11 on the rear end side, the flange 3a is inserted between the support walls 17a, 17b, 17c and the locking claw 24 and pushed from above. As a result, the locking claw 24 slides on the flange 3a while being elastically deformed by being pressed by the flange 3a. When the end cap 11 is pushed in by a predetermined amount, the locking claw 24 is elastically restored at the base end of the flange 3a and is bent. Is engaged. At this time, the locking wall 19 of the end cap 11 is engaged with the notch 27 of the flange 3a. Therefore, the rear end portion of the waist molding 2 is fixed to the flange 3 a in a positioned state by the function of the locking clip 14 of the end cap 11.

  Further, in the end cap 10 on the front end side, the flange 3a is inserted between the support walls 34 and 40 and pushed from above. As a result, the engaging protrusion 31 protruding from the support wall 34 slides on the flange 3a while being bent and deformed with the base side as a fulcrum, and the end cap 10 is pushed into the locking hole 38 when the set amount is pushed in. Then, the shape is restored and fitted into the locking hole 38. At this time, in the engaging protrusion 31, the top displacement regulating surface 37 abuts the inner surface of the upper side of the locking hole 38 along the longitudinal direction. Therefore, the front end portion of the waist molding 2 is fixed to the predetermined position of the flange 3a through the end cap 10 in a positioned state.

  On the other hand, when removing the waist molding 2 from the door outer panel 3, first, an operator puts his hand in the direction of the rear end of the flange 3 a of the door outer panel 3 from the opening 41 of the door inner panel 4, and The entire end cap 11 is pushed upward while pushing up the operation claw 25 constituting the locking clip 14.

  Then, an operator pulls off the waist molding 2 from the upper side of the flange 3a of the door outer panel 3. At this time, an operator pulls out the waist molding 2 sequentially from the rear end side, and finally pulls the front end of the waist molding 2 toward the upper rear side. As a result, the taper surface 36 of the engagement protrusion 31 of the end cap 10 on the front end side comes into contact with the edge of the engagement hole 38 of the flange 3 a, and the engagement protrusion 31 is on the edge of the engagement hole 38 with the taper surface 36. While sliding, the base portion is elastically bent and deformed. As a result, the engagement protrusion 31 and the engagement hole 38 are disengaged, and the waist molding 2 is completely removed from the flange 3a.

  As described above, in the mounting structure of the waist molding 2, the engagement protrusion 31 having the tapered surface 36 at the upper rear end is provided on the end cap 10 on the front end side, and the engagement protrusion 31 locks the flange 3a. Since the waist molding 2 is removed, the waist molding 2 is pulled upward and the taper surface 36 is slid on the edge of the locking hole 38 when the waist molding 2 is removed. The engagement between the cap 10 and the flange 3a can be easily released. Therefore, when this mounting structure is adopted, even if there is not enough space to insert a hand or a tool in the upper front end direction of the door outer panel 3, the end cap 10 is not damaged and the waist molding 2 is not damaged. The front end portion can be easily removed from the flange 3 a together with the end cap 10.

  In the case of this embodiment, since the engagement protrusion 31 of the end cap 10 is formed in a claw shape that can be bent and deformed with the root portion as a fulcrum, the engagement when the waist molding 2 is pulled to the upper rear side. There is an advantage that the protrusion 31 and the locking hole 38 can be easily released.

  Furthermore, in this embodiment, a displacement restricting surface 37 is provided on the top of the engagement protrusion 31 of the end cap 10, and a tapered surface 36 is provided adjacent to the rear end side of the waist molding 2 of the displacement restricting surface 37. Therefore, the upper displacement of the front end of the waist molding 2 is restricted without obstructing the sliding of the tapered surface 36 and the end edge of the locking hole 38 when the waist molding 2 is removed. The portion can be stably held at the set position on the flange 3a.

  In this embodiment, only the front end cap 10 engages the engagement protrusion 31 having the tapered surface 36 with the locking hole 38 on the flange 3a side, and the end cap 11 on the rear end Since the locking clip 14 is firmly fixed to the flange 3a, there is an advantage that the holding strength of the entire waist molding 2 in a state where the waist molding 2 is attached to the flange 3a can be increased.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary.
