Abstract

PROBLEM TO BE SOLVED: To restrict an inclination attitude of a clip in a roof groove. SOLUTION: A clip C is retained to a clip-retaining portion 18 of a mounting jig J prior to mounting the clip C to a roof groove R. When the clip C is retained to the clip-retaining portion 18, since a falling down-stop portion 16 projection-formed on the clip C is engaged with a bottom surface of the clip- retaining portion 18, it is restricted that the clip C is inclined to a second adhered surface 9 side even if the clip C laterally slides such that the second adhered surface 9 is urged to a side wall 6 of the roof groove R. Accordingly, the clip C is urged to the side wall 6 at a right attitude. Therefore, a roof molding M can be appropriately attached to a molding attachment portion of the clip C.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting a roof molding of an automobile, and a clip used for the method.
Further, the present invention relates to a mounting jig.

[0002]

2. Description of the Related Art Conventionally, a roof of an automobile is shown in FIG.
As shown in the figure, decorative moldings M are mounted in pairs on the left and right. The location where the roof molding M is attached is a roof groove R that is recessed along the front-rear direction of the vehicle.
At the bottom of the roof groove R, two panels are superimposed, and the roof molding M plays a role of covering up such a portion. Normally, the roof molding M is mounted using the resin clip C1 according to the following procedure.

After the electrodeposition coating process for the body panel of the automobile, a sealer 50 is applied to the roof groove R along the longitudinal direction in order to seal a joint portion of the panel. Next, the clip C1 is attached. In order to adhere the clip C1 to the bottom surface and one wall surface of the roof groove R, thermosetting tapes 51 and 52 are attached to two positions corresponding to these in advance. I have. Clip C1
When installing in the roof groove R, first, while strongly pressing the bottom surface, that is, the portion where the sealer 50 is applied,
It is pressed against the side wall while sliding on the sealer 50 toward the side wall to be bonded. If the pressing on both sides is insufficient, the adhesive strength will be insufficient and the final clip C
1 is incompletely mounted.

[0004] Thereafter, the body panel goes through a drying oven and undergoes steps such as intermediate coating, baking, top coating, and baking. Due to the heat applied during the drying or baking process, the clip C1 is firmly adhered by the thermosetting tapes 51 and 52.

Incidentally, a plurality of clips C1 are attached to each roof groove R. In the middle part of the roof groove R, the worker directly presses the roof groove R for mounting, but since an external force tends to act on the end of the roof molding M as compared with the middle part, the clip C1
Must be especially tightly fitted. Therefore, conventionally, the clip attached to the end of the roof groove has been designed to be surely pressed against the roof groove R by using a dedicated mounting jig J1. The mounting jig J1 has a grip on the upper side, and a holder H for holding the clip easily at the lower end. The holder portion H is formed with a substantially U-shaped concave portion. When the entire clip C1 is loosely fitted therein, the clip C1 is held by the frictional force on both side surfaces of the holder portion H.

[0006]

The operator first presses the clip C1 attached to the tip of the above-mentioned mounting jig against the bottom surface of the roof groove R, and then presses the clip C1 on the side wall 54 while sliding sideways. At this time, the clip C1 may fall into the step 53 where the panels are overlapped, rattle in the mounting jig J1, and may be inclined with respect to the side wall 54. Further, although the overlapped portions of the panels are joined by welding, it is well known that the dimensions in which the panels are overlapped vary. For this reason, when the groove width of the roof groove R is increased, when the clip C1 is slid, the stroke for passing over the step, that is, shifting without support from below becomes large, and the clip Is unstable, and it is easy to be inclined. When the clip C1 is tilted in this manner, a situation occurs in which the clip C1 cannot be properly mounted on the roof molding M.

SUMMARY OF THE INVENTION The present invention has been developed to meet such a demand. It is an object of the present invention to restrict a clip from being inclined when a clip is attached by using a mounting jig. Accordingly, it is an object of the present invention to provide a method for properly attaching a roof molding, and a clip and a mounting jig thereof.

[0008]

According to a first aspect of the present invention, there is provided a roof groove of a vehicle having a side wall and a bottom wall.
A clip is held by a mounting jig, and a first adhesive surface of the clip to the bottom wall and a second adhesive surface to the side wall of the clip are pressed to fix the clip in the roof groove. A method of attaching a roof molding along the roof groove through the roof molding, wherein the first and second adhesive surfaces are held together when the clip is held by the attachment jig. In addition to being exposed, the clip is positioned so as to restrict the entire clip from tilting toward the second adhesive surface. According to a second aspect of the present invention, a roof molding is provided in a roof groove which is recessed in a vehicle roof along the front-rear direction and has a side wall and a bottom wall, and is fixed along the roof groove. A clip, a molding mounting portion capable of mounting the roof molding,
A first adhesive surface that can be adhered to the bottom wall of the roof groove, a second adhesive surface that can be adhered to the side wall, and a clip that is held by the mounting jig, thereby engaging with the jig. The clip is characterized in that the clip is provided with a fall prevention portion that can restrict the inclination of the clip toward the second adhesive surface. According to a third aspect of the present invention, in the second aspect, the mounting jig has a clip holding portion that opens downward, and the clip is fitted into the clip holding portion from the opening and fitted. In the inserted state,
A part including the first and second adhesive surfaces is exposed and held in a state where play is allowed, and a part protruding outside from the clip holding portion is provided with the stopper. The clip portion is protruded, and the stopper portion can be locked to the opening edge of the clip holding portion. Furthermore, the invention according to claim 4 is a grip portion, the clip holding portion provided at an end of the grip portion, and provided so as to be able to advance and retreat with respect to the clip holding portion, and to advance into the clip holding portion. And an eject portion that projects the clip when ejected and allows the clip to be ejected from the clip holding portion.

[0009]

According to the first and second aspects of the present invention, the clip is held between the mounting jigs. At this time, the first and second bonding surfaces are both exposed to the outside. Then, the first adhesive surface of the clip is pressed against the bottom wall of the roof groove, and the second adhesive surface is pressed against the side wall of the roof groove. At the time of pressing against the side wall, the stopper of the clip is locked to the jig, so that the entire clip is prevented from tilting to the second adhesive surface side, that is, the clip is in a positioned state. The clip can be adhered to the side wall of the roof groove while maintaining the proper posture. Thus, the molding is properly attached to the molding attachment portion of the clip. According to the third aspect of the present invention, the clip is held in a state where rattling (movement) is allowed with respect to the clip holding portion of the mounting jig. Therefore, even when the clip is already inclined in the initial state of attachment to the attachment jig, if the clip is pressed against the bottom wall of the roof groove, it is automatically corrected to the normal posture following the bottom wall. According to the invention of claim 4, the clip is held in the clip holding portion of the mounting jig. Then, when the pressing against the first and second adhesive surfaces is completed, the eject portion is advanced into the clip holding portion and hits the clip. By doing so, the clip can be reliably discharged from the clip holding portion.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. Two roof grooves R are recessed on the left and right sides of the roof of the automobile along the longitudinal direction of the automobile, and a roof molding M is attached to each of the grooves. 1 to 10 show the structure on one side thereof.

The roof molding M is formed so as to cover the roof groove R over the entire length, and has a metal core 1 having a substantially C-shaped cross section and a soft resin portion 2 laminated on the surface thereof. Consists of The soft resin portion 2 has sealing lips 3A and 3B extending along the length direction at portions facing both side edges of the roof groove R, respectively. Note that both side edges inside the roof molding M are first and second flange edges F1 and F2 for attaching a clip C described later.

On the other hand, two roof panels are overlapped on the bottom wall of the portion where the roof groove R is formed, and these seams are joined by welding. Prior to attachment of the clip C, a plastic sealer 4 is applied to the joint along the length direction to achieve waterproofing.
In this embodiment, when the clip C is attached to the roof groove R, the bottom wall 5 on the upper side of the panel and the side wall 6 rising from the panel on the lower side are bonded to the clip C. Used for business.

Next, the clip C will be described. The clip C is integrally formed of a synthetic resin material. The clip C has a base 7, the lower surface of which is a first adhesive surface 8 to which a thermosetting tape is adhered via an adhesive. However, when the bottom wall 5 of the roof groove R is inclined and the groove depth is changed as in this embodiment, the first bonding surface 8 is also inclined along the length direction. It is formed horizontally, but it may be formed horizontally depending on the situation on the roof side.

On one long side of the base 7, the entire edge rises upward to form a side piece 10, the outer surface of which is a second adhesive surface to which a thermosetting tape is adhered via an adhesive. There are nine. Clips C are provided on both ends of the upper edge of the second adhesive surface 9.
A pair of regulating protrusions 11 for preventing the whole from being inclined are formed to protrude outward. The two regulating protrusions 11 come into contact with the side wall 6 of the roof groove R when the clip C is held at an insufficient depth and at an angle, for example, at the time of initial attachment to the attachment jig J. Although the posture of the clip C is easily corrected, the step 6A on the upper edge of the side wall 6 when the clip C is properly attached.
It is located above.

On the other hand, a molding mounting portion for mounting a roof molding M is provided on the upper surface of the base 7. The molding attachment portion is constituted by a total of three molding attachment pieces 12A and 12B. That is, the two long sides of the base 7 are erected at two places at both ends on the side opposite to the side on which the side piece 10 is provided (end side molding mounting piece 12A), and on the side opposite to this. It is arranged inside the side piece 10 and at the center position (center side mounting piece 12B). Each mall mounting piece 12
A and 12B are allowed to bend and deform, and the claw portions 13 formed at the respective ends are elastically engaged with the opening edges of the roof molding M, so that the entire clip C is prevented from falling off to the roof molding M. I can do it. However, the width dimension of the center side molding piece 12B is the end side molding piece 12B.
A is set to be about twice as large as A.

Further, at the center of the long side of the base 7 on which the molding attachment pieces 12A on both ends are provided,
A receiving piece 14 for receiving the first flange edge F1 side of the roof molding M is provided upright. At the tip of the receiving piece 14, an overhang portion 14A is bent horizontally outward, and the first flange edge F1 of the roof molding M is connected to the claw portion 13 of the both end side molding mounting piece 12A and the receiving piece. 14 and overhangs 14A. On the other hand, the second flange edge F2 of the roof molding M is sandwiched between the claw portion 13 of the center molding attachment piece 12B and the receiving edge 10A formed on the upper edge of the side piece 10.

On the upper surface of the base 7, between the center side molding mounting piece 12 B and the end side molding mounting piece 12 A,
A pair of contact pieces 15 for strengthening the frictional force with respect to the mounting jig J stand up so as to be able to bend inward. Double contact piece 1
As shown in FIG. 3, reference numeral 5 includes a main portion 15A formed in a direction parallel to the short side portion of the clip C, and a reinforcing portion 15B which is bent inward at a substantially right angle from the main portion 15A.
The front surface of the reinforcing portion 15B is disposed so as to be substantially flush with the front surfaces of the receiving piece 14 and the both end side molding attachment pieces 12A, and is formed to have substantially the same height as the receiving piece 14.

Further, the base 7 is provided with overhanging portions 16 at the outer positions of the both end side molding mounting pieces 12A, respectively. When the clip C is mounted to the mounting jig J to be described below to a regular depth, the both stopper portions 16 can be locked to the lower end surface of the mounting jig J. By doing so, it is possible to restrict the entire clip C from falling down toward the second bonding surface 9 (clockwise in FIG. 5).

Next, the mounting jig J will be described. The mounting jig J is composed of a grip portion 17 and a clip holding portion 18 for holding the above-mentioned clip C. It is formed of a resin material. The clip holding portion 18 is disposed at a position deviated to one side on the end surface of the tip portion of the grip portion 17, and the rear surface thereof is substantially flush with the outer surface of the grip portion 17. Also, the clip holding section 18
Is formed wider than the grip portion 17. The clip holding portion 18 has a substantially U-shaped outer frame piece 19 opening downward.
And an inner frame piece 20 that projects inward from the inner peripheral edge of the outer frame piece 19 and is thinner than the outer frame piece 19.

The width of the inside of the outer frame piece 19 is a clip C.
Is formed with a width which is the same as or slightly smaller than the entire width (W1 dimension shown in FIG. 2). As shown in FIG. 5, the thickness of the inner frame piece 20 is sufficiently smaller than the distance between the molding pieces 12A on both ends and the side piece 10, so that the inner frame piece 20 has a play Can be fitted. But,
The inner width (opening width) of the inner frame piece 20 is set to be substantially equal to or slightly smaller than the distance between the outer surfaces of the contact pieces 15 of the clip C (the dimension W2 shown in FIG. 2). As a result, the clip C is held by the frictional force between the inner and outer frame pieces 19 and 20 in the clip holding portion 18, but the clip C itself has appropriate elasticity. Since the frictional force of the clip C is not so high, the clip C is allowed to rattle moderately in the clip holding portion 18 and the fitting direction and the clock C itself in the clockwise direction shown in FIG. ing.

The mounting jig J according to the present embodiment is
Is provided with an eject mechanism for projecting the clip C, which has been attached to the roof groove R, from the clip holding portion 18. That is, a through hole 21 is formed from the upper end surface of the grip portion 17 along the axis, and opens into the clip holding portion 18. A protruding shaft 22 is slidably incorporated in the through hole 21, and an upper end side thereof is an operation convex portion 23 which protrudes from the upper end surface of the grip portion 17 and can be pressed. On the other hand, the lower end side is an eject portion 24 for discharging the clip C. The eject section 24 is always connected to the clip holding section 1.
8, but is in a substantially non-contact state with respect to the clip C which is properly attached. Then, when the operation convex portion 23 is pressed, it is greatly protruded into the clip holding portion 18 and presses the upper edge of the receiving piece 14 so that the clip C
Can be discharged.

The entire shaft 22 is prevented from falling out by locking a flange 26 of the shaft 22 to a throat portion 25 formed at the center of the through hole 21.
A return spring 27 is incorporated in the through hole 21. The return spring 27 contacts the flange of the shaft 22,
The shaft 22 is urged in the lifting direction.

Next, the operation and effect of this embodiment configured as described above will be specifically described. Prior to mounting the roof molding M, the clip C is first installed in the roof groove R. This operation is performed, as described above, on the roof groove R
After the sealer 4 is applied.

The clips C are arranged at predetermined pitches along the longitudinal direction of the roof groove R. At the intermediate portion, the clip C is directly attached by hand, but at the end, the clip C is attached while being held by the attachment jig as follows.

When the clip C is mounted on the mounting jig J, the inner frame piece 20 of the mounting jig J is loosely fitted between the molding pieces 12A on both sides of the clip C and the side pieces 10, At the same time, the side surfaces of the both end side molding attachment pieces 12A are brought into contact with the inner surface of the outer frame piece 19, and the side surfaces of the contact pieces 15 are brought into contact with the inner surface of the inner frame piece 20, respectively. At this time, as described above, since the clip C is in a state of being freely movable with respect to the clip holding portion 18, the clip C may be held at an angle particularly when the insertion into the clip holding portion 18 is insufficient. (See FIG. 6). However, even if the clip C is held obliquely in this way, when the sealer 4 is pressed against the bottom wall 5 of the roof groove R to which the sealer 4 is applied and comes into close contact with the bottom surface of the base 7, the clip C is moved to the clip holding portion 18. On the other hand, it is inserted to the normal depth and is automatically corrected to the normal posture at the same time (see FIG. 7).

Next, as shown in FIG.
The entirety of the clip C is slid by utilizing the plasticity of the sealer 4 while being held at the second position, and the second adhesive surface 9 is pressed against the side wall 6 of the roof groove R. As described above, the clip C tends to assume the inclined posture (the posture inclined in the clockwise direction in FIG. 7) due to a step on the bottom wall 5 of the roof groove R during the skidding. However, according to the present embodiment, since both the stoppers 16 are locked to the lower end surface of the outer frame piece 19, the falling in such a direction is reliably restricted. Therefore, the second bonding surface 9 can be pressed against the side wall 6 while keeping the normal posture. Thereafter, when the operation convex portion 23 of the mounting jig J is pressed against the return spring 27, the eject portion 24 protrudes into the clip holding portion 18 and presses the receiving piece 14 of the clip C. Is reliably discharged from the clip holding portion 18. Therefore, it is possible to avoid a situation in which the clip C peels off when the mounting jig J is lifted.

Thus, the clip C is brought into a temporary bonded state by the first and second bonding surfaces 9 being pressed against the inner surface of the roof groove R. Thereafter, as the body panel undergoes various drying steps, the clip C is brought into a regular bonding state by the thermosetting tape stuck to both bonding surfaces, and is firmly fixed to the inner surface of the roof groove R.

When the mounting of the clip C is completed as described above, the roof molding M is arranged along the roof groove R, and the clip is fitted as it is. At this time, the both end side molding attachment pieces 12A and the center side molding attachment pieces 12B are each bent inwardly and deformed, so that each claw portion 13 can pass through the opening portion of the roof molding M, and after passing, When the whole is elastically restored, each claw portion 13 is locked to the opening edge of the roof molding M, so that the roof molding M is mounted in a state where it cannot be removed.

As described above, according to the present embodiment, the clip C is provided with the stopper 16 so that the clip C is locked to the mounting jig J, whereby the entire clip C is tilted toward the second bonding surface 9. Therefore, the clip C is prevented from falling down when it slides sideways so as to press the clip C against the second adhesive surface 9, and the clip C is held in the normal position in the side wall 6 of the roof groove R.
Can be adhered to. Therefore, the roof molding M can be mounted in a favorable state. That is, the clip C is positioned with respect to the mounting jig to fix the mounting posture. However, simply by positioning, other methods, such as providing a quadrangular prism-shaped projection on the clip C side, and setting the mounting jig in place. A square hole into which this is fitted may be perforated on the tool J side. However, if the clip C is held in such a state that it is completely fixed in the mounting jig, rigorous work is required when setting the clip J on the mounting jig. This is disadvantageous in that the groove R can follow the bottom wall 5. On the other hand, as in the present embodiment, the clip C has a certain degree of freedom with respect to the mounting jig J (at least the inclination to the second adhesive surface 9 side is restricted, but the clip C moves to some extent in the other direction). The state in which the holding groove is allowed) can be roughly held by the mounting jig, and the roof groove R
The effect that the flexibility at the time of attachment to the device is also improved is obtained.

Further, in this embodiment, since the mounting jig J having the eject function is used, the mounting condition of the clip C after the mounting is once made is not spoiled.
