In particular, the present invention relates to a structure that improves the positioning accuracy when the clip is attached to the molding and simplifies the work.

《Prior art》 On the outer panel of the vehicle door, there are No. 59-192444 and No. 61-38.
As shown in No. 248, etc., a side protector molding is attached to prevent a dent due to a collision when opening and closing a door and to add an accent to the appearance. This side protector molding is made by extruding rubber, vinyl chloride, or other resin integrally on a core material that is made by processing stainless steel or the like into a lip groove in cross section, and mounting a plurality of clips inside the lip groove,
The tip of each clip is pressed against a plurality of mounting holes opened to the door outer plate side, and is elastically fitted to fix the molding to the door outer plate.

In this mounting structure, clips are pre-assembled on the molding provided to the assembly line, but in order to assemble with one touch, the mounting holes and clips on the door outer plate must be aligned. Must match exactly. For this reason, conventionally, as shown in FIG. 4, the mounting base portion 2 of the clip 1 has a C shape in a molding 3 having a C-shaped cross section.
In a state of being fitted in the shape clip groove and being positioned at the correct position, a pair of triangular locking projections 4 are formed on both edges of the lip groove on both sides of the mounting base 2 by embossing. So as to project inward so that the mounting base 2
The structure was used to fix the.

In Japanese Utility Model Laid-Open No. 61-38248, a pair of locking claws are provided on the surface side of the mounting base of the clip that faces the inner surface of the molding, while the inner surface of the molding has two L-shaped cross sections. A structure is adopted in which an interlocking rail is provided in the longitudinal direction, the locking claws are positioned inside the engagement rails, and the respective engagement rails are sandwiched by the locking claws corresponding to the mounting base. On the other hand, in Japanese Utility Model No. 59-192444, while the bolts on the inner surface of the molding are projected, the insertion hole and the engaging hole with the claw piece are provided on the surface of the mounting base of the clip that faces the inner surface of the molding. A structure in which the head portion of the bolt is moved from the state where the head portion of the bolt is inserted into the large-diameter insertion hole to the engagement hole with the claw piece to prevent the clip from coming off. Has been adopted.

<< Problems to be Solved by the Invention >> However, according to the structure shown in FIG. 4, the positional accuracy is low, and the spring protrusions or the like during processing cause a gap between the locking projections 4 on the back surface side of the molding 3 (in the figure, However, there is a drawback that the portion (section L) rises up, and this portion interferes with the outer panel of the door and may not come into close contact. In such a case, the appearance is deteriorated, and water enters through the gaps in this portion, which causes rusting. Further, in this structure, both sides of the mounting base 2 are sandwiched by the locking projections 4, so that the clip 1 may be restricted to a slight movement after being fixed. When the movement is restricted in this way, there is a case where the molding is not flexible, the dimensional tolerance with respect to the mounting hole cannot be absorbed, and the molding cannot be mounted.

In addition, in the structure of No. 61-38248, there is a need to add a locking claw on the clip side and also a long engagement rail on the molding side. The regular position of is easy to shift. In addition, the actual development Sho 59-19244
In the structure of No. 4, in addition to the complicated mold structure of the clip, the bolt must be fixed to the molding side by welding, etc. There's a problem.

Therefore, an object of the present invention is to provide a molding attachment clip that can fix the attachment base of the clip to the inside of the molding with high accuracy, simplifies the mounting work, and does not cause the molding to partially lift.

<Means for Solving the Problems> In order to achieve the above object, the present invention is to fix a molding having a substantially C-shaped cross section to the body side, and is arranged in a C-shaped lip groove of the molding. A mounting base that is fitted and fixed by using a positioning locking projection integrally formed on the molding; and a mounting base that is fixed to the molding and protrudes to the back side of the molding and is provided on the body side. In a molding attachment clip integrally formed with an engagement clip portion that is fitted and fixed in a mounting hole, the positioning locking projections are set at two locations inside the C-shaped both edges of the molding. Correspondingly, the clips are located on both sides of the engaging clip portion, and a pair formed on the surface portion of the mounting base portion facing both edges of the C-shaped clip when placed at the regular position of the C-shaped clip groove. With locking holes Then, the mounting base is positioned and fixed to the molding by the engagement of the locking holes and the positioning locking projections.

<Operation> According to the above configuration, since the positioning locking projections are provided only at two positions for one clip, it is possible to prevent the molding from rising due to the springback phenomenon during embossing as in the conventional case. Also, the clip can be moved slightly inside the molding by, for example, providing the locking hole relatively large and loosening the engagement between the locking projection and the locking hole, and fixing the molding to the body side. It has a great deal of flexibility in working.

<< Embodiment >> An embodiment of the present invention will be described below in detail with reference to the drawings. 1 to 3, reference numeral 10 is a door outer plate which is a body, reference numeral 12 is a side protector molding (hereinafter referred to as a molding) fixed to the door outer plating 10, and reference numeral 14 is a molding attachment clip of the molding 12. Is. A plurality of clip mounting holes 16 are formed in a row on the door outer plate 10 (only one is shown in the figure), and the clips 14 are formed in a number and at intervals corresponding to the mounting holes 16. Attached to 12.

The molding 12 is a stainless steel core material having a C-shaped cross section.
A resin 18a such as rubber vinyl chloride is extruded integrally on the outer periphery of 18, and is cut according to the length dimension of the door, and the front and rear open ends thereof are covered with a gap (not shown) or the like.

The clip 14 is made of a plastic molded body, and has a rectangular plate-shaped mounting base portion 20 fitted and fixed in the C-shaped clip groove 12a of the molding 12 and integrally formed in the central portion of the mounting base portion 20 so as to project. A packing 24 made of a soft foam molded body that is fitted to the base of the clip portion 22 in advance, and a soft material such as urethane rubber that is fitted to the outer periphery of the tip of the clip portion 22. A bush consisting of
26 and.

The mounting base 20 is fixed in a state in which both ends are pulled by rotating the mounting base 20 in the C-shaped lip groove 12a by 90 degrees.

Then, both ends thereof are formed with arcs for one-way rotation so as to be easily rotated, and antenna-shaped elastic locking pieces 20a are further formed on one end side, and the elastic locking pieces 20a are elastically deformed at the time of mounting. As a result, the dimensional tolerance of the C-shaped clip groove 12a in the depth direction is absorbed, and the C-shaped clip groove 12a has a predetermined locking torque.
held inside a.

In addition, a pair of locking holes for positioning are provided on the surface of the mounting base 20.
20b is formed. The locking holes 20b are located on both sides of the clip portion 22, and when the clip 14 is arranged at the regular position of the C-shaped clip groove 12a, the mounting base portion faces both edges of the C-shaped portion.
It is provided on 20 surface parts.

On the other hand, on both edges of the lip groove 12a of the molding 12, a pair of locking projections 12b for positioning are projected inward with a triangular cross-section by embossing or the like at the same intervals as the formation pitch of the mounting holes 16. Has been formed.

The clip portion 22 has a boss portion 22a, a shell-shaped head portion 22b formed at the head of the boss portion 22a with a diameter larger by one step, and a lower portion of the head portion 22b. The clip portion 22 projects obliquely on both sides of the boss portion. It is composed of a pair of elastic locking pieces 22c formed.

The bush 26 has a tubular portion 26a fitted just below the head portion 22b.
And a flange portion 26b integrated with the lower peripheral edge of the tubular portion 26a.

In the above configuration, when the mounting base 20 is correctly positioned at the mounting position of the molding 12 and rotated 90 degrees, each locking projection 12b elastically engages the inside of the locking hole 20b, and the mounting base 20
Hold and position in the correct position. In this state, both sides of the mounting base 20 are held in a state of being stretched on both sides of the C-shaped clip groove 12a, and are elastically supported by the elasticity of the elastic locking pieces 20a so as to be slightly movable vertically. Further, since the locking hole 20b is loosely coupled to the locking projection 12b, it is held so as to be slightly movable also in the longitudinal direction of the molding 12.

In this embodiment, the locking projection 12b is formed on the molding 12 in advance. However, the locking projection for positioning is formed by post-processing while the mounting base 20 is engaged with the regular position in the C-shaped clip groove 12a. The locking protrusion 12b may be engaged with the locking hole 20b at the same time when the projection 12b is formed. In this case, the mounting base 20 has a function as a pressure receiving plate for the crimping tool, and a receiving jig is not required, so that the processing is simplified.

Next, a case where the molding 12 is fixed to the door outer plate 10 with the clip 14 will be described.

First, the clip 14 includes the packing 24 and the bush 2 as described above.
6 is fitted in the clip portion 22 and fixed in the correct position inside the C-shaped clip groove 12a of the molding 12. To assemble this on the door outer plate 10 on the vehicle assembly line, simply refer to FIG. As shown in (a), by positioning the molding 12 at the correct position on the door outer plate 10 and pressing it, the clip portion 22 fits into the mounting hole 16, and the fixing work is performed as shown in FIG. 3 (b). Complete.

A slight displacement at this time is absorbed by the freedom of movement of the clip 14. Further, in the initial stage of this pressing work, first, the head portion 22b of the clip portion 22 is inserted into the inside of the mounting hole 16, and the outer periphery of the tubular portion 26a of the bush 26 below it contacts the inner periphery of the mounting hole 16. If the pushing operation continues in that state, the peripheral edge of the mounting hole 16 contacts the flange portion 26b. Since the bush 26 is highly elastic and flexible, it is relatively retracted as the clip portion 22 is pushed into the mounting hole 16 and covers the outer periphery of the elastic locking piece 22c. The elastic locking piece 22c elastically contracts in the radial direction as it is inserted into the mounting hole 16, and when it reaches the lower part, it elastically expands and is retained as shown in FIG. 3 (b). However, the cylindrical portion 26a of the bush 26 remains in the outer periphery.

Further, the flange portion 26b of the bush 26 is pressed against the surface of the mounting base portion 20 together with the packing 24, and this portion is sealed in the crushed state of the packing 24. As described above, there is no direct contact between the clip portion 22 and the mounting hole 16, and the elasticity of the bush 26 prevents the coating film from peeling off.

<< Advantages of Device >> As described above, in the molding mounting clip according to the present invention, the locking projections for mounting the molding are provided at two locations inside the C-shaped edges with respect to one clip. Therefore, it is possible to prevent the molding from rising due to the springback phenomenon during embossing as in the past, and to prevent deterioration of appearance and rust. Since the locking projection is formed so as to intersect with the center of the mounting hole on the body side as shown in the embodiment, the positioning accuracy of the clip is high because of the relationship with the locking hole on the clip side.

In addition, the clip can be slightly moved while maintaining the engaged state in the molding by, for example, providing the locking hole in a large size and loosely engaging the locking projection and the locking hole, and the molding can be moved on the assembly line. It has a great deal of flexibility when it is fixed to the body and also improves the yield.
