Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for a roof molding.

[0002]

2. Description of the Related Art For example, a roof molding M used for a roof panel P of an automobile has been mounted using a clip C made of resin as shown in FIG. Briefly, a groove 50 is formed in the roof panel P along the longitudinal direction, and a stud bolt S
Is erected. The clip C is provided with a pair of retaining claws 51 on the lower side thereof which are engaged with the stud bolts S to prevent the whole from coming off. On the other hand, a pair of locking claws 52 are provided on the upper side of the clip C in a back-to-back manner, each of which can elastically engage with the flange edges F1 and F2 provided on both side edges of the molding M, respectively. It can be bent and deformed. Thus, the clip C is pre-attached to the molding M by the locking claw 52. In this state, the molding M is pushed in while being fitted to the groove 50, whereby the retaining claw 51 is locked to the stud bolt S, and the clip
The installation of the mall is completed.

[0003]

However, in the above, the following points were pointed out as points to be solved. That is, since the mounting on the molding M is performed by bending the locking claw 52 and locking it on the flanges F1 and F2, when a force in the lifting direction acts on the molding M, the locking claw 52 is disengaged. It cannot be denied that there is a possibility that the engagement with the flanges F1 and F2 will be released due to deformation in the direction (direction of falling backward). In particular, the curvature of the corners of the flange edges F1 and F2 at which the locking claws 52 are locked tends to vary for manufacturing reasons. Therefore, at the flange edge where the radius of curvature has become large, the catch of the locking claw 52 is small, and it is easy to come off. However, it is not conceivable to increase the rigidity of the locking claw in order to make it difficult for the locking claw to come off. Will reduce the performance.

[0004] For these reasons, conventionally, no appropriate measure has been found as a measure for strengthening the prevention of the detachment of the mall. The present invention has been devised in view of the above-mentioned conventional problems, and an object of the present invention is to provide a clip which is easy to be attached to a molding and has a high effect of preventing detachment from a roof panel. .

[0005]

According to a first aspect of the present invention, there is provided a panel-side locking portion which can be fixed to a roof panel of an automobile, and at least a pair of locking claws provided in a back-to-back manner. For a roof molding having flange edges formed at both end edges, a molding side engagement portion that allows both engagement claws to enter and lock inside the flange edges while bending in a direction approaching each other. The panel-side locking portion and the molding-side locking portion can be connected to each other, and the panel-side locking portion is provided with a flexure restricting portion. By separating the two locking claws with each other in accordance with the connecting operation, the bending deformation of the locking claws in the direction in which the locking claws are disengaged from the flange edge can be regulated.

According to a second aspect of the present invention, in the first aspect, the panel-side locking portion and the molding-side locking portion are integrated by a breakable thin connection edge. It is a feature.

Further, according to a third aspect of the present invention, in the molding side locking portion, a base portion is disposed at a central portion, and a pair of arm portions extend from the base portion along the length direction of the molding, and The portion can be flexibly deformed in the width direction of the molding, and can be elastically locked to the flange edges by the locking claws provided at the distal end thereof, while the panel-side locking portion is A substrate provided with a locking means for the roof panel side is provided, and the bending restricting portion is protruded from an end of the substrate.

[0008]

According to the first aspect of the present invention, when the clip is attached to the molding, the engaging claw of the engaging portion on the molding side is bent to be engaged with both flange edges. The attachment to the roof panel is performed by the panel-side locking portion. In the process of connecting the molding-side locking portion and the panel-side locking portion, the deflection regulating portion enters between the locking claws. For this reason, in a state in which the engaging portions are completely connected and the molding is mounted on the roof, the bending of the engaging claws in the disengaging direction is restricted, so that the molding is securely prevented from coming off. On the other hand, since the locking claw can be freely bent and deformed when mounted on the molding, the mounting on the molding can be easily performed.

Further, in the case where the panel-side locking portion and the molding-side locking portion are connected by a thin connecting edge as in the second aspect of the present invention, the clip is formed as a single member, so that the handleability is improved. Excellent. In the thus formed one, it is broken when the molding side locking portion and the panel side locking portion are joined, whereby the bending restricting portion can advance between the locking claws.

Further, according to the third aspect of the present invention, the arm portion is extended from the base portion along the length direction of the molding, and a locking claw is provided at a tip portion thereof. By doing so, it is possible to ensure a long length of the arm portion,
Since the locking claw is provided at the free end, that is, the bending deformation is facilitated, so that it can be easily mounted on the molding.

Embodiments of the present invention will be described below with reference to the drawings. Embodiment 1 FIGS. 1 to 7 show Embodiment 1 of the present invention. First, the structure of the roof side of the vehicle will be described with reference to FIG. 5. The roof of the vehicle has a structure in which two panels P1 and p2 are combined, and a groove 1 is formed in the lengthwise direction at the joint. . Stud bolts S are provided on the bottom surface of the groove 1 at appropriate intervals by welding or the like. Stud bolt S is shaft part S1
And a disk-shaped head S2 provided at the upper end of the shaft portion S1.

The molding M to be attached is formed so as to cover a part of the groove 1 along the length direction. The molding M has a core 2 and is entirely covered with a covering portion 3 made of a soft resin material. Further, the molding M has its both ends gently bent inward to form first and second flange edges F1 and F2.
The two flange edges F1 and F2 are further suspended downward to form side pieces 4 having different lengths. In addition,
A flexible upper lip piece 5 elastically contacting the upper portion of the groove 1 is formed on the first flange edge F1, and a flexible lower lip elastically contacting the bottom surface of the groove 1 at the lower end of the side piece 4 on the second flange edge side. A piece 6 is formed.

The clip C is integrally formed of a synthetic resin material. As shown in FIG. 1, the entirety of the clip C is a panel-side locking portion 7 for fixing to the roof panels P1 and P2.
And a molding side locking portion 8 for fixing to the molding M side. First, the panel-side locking portion 7 will be described. The panel-side locking portion 7 has a flat plate-shaped substrate 9 that can be contacted along the bottom surface of the groove portion 1, and a through hole for the stud bolt S is provided at the center thereof. 10 is open. This through hole 1
Reference numeral 0 denotes a play insertion portion 10A formed so that the head portion S2 of the stud bolt S can be freely inserted, as shown in FIG.
A and a shaft portion S1 of the stud bolt S
Is inserted, but the head S2 has a flange 13 for receiving the lower surface thereof.
And an engaging portion 10B that protrudes and makes the head S2 unable to pass through. Then, the loose insertion portion 10A and the engagement portion 10B
A pressing claw 11 is formed obliquely toward the engaging portion 10B at a boundary portion between the holding portion 11 and the pressing claw 11. The head S2 of the stud bolt S moves from the free insertion portion 10A to the engaging portion. In addition to being able to bend and deform to allow the stud bolt S to engage with the side surface of the head S2 moved to the engaging portion 10B, the stud bolt S is detented.

The above-described through hole 1 is formed on the substrate 9.
A pair of connecting pieces 12 are erected so as to face each other on both sides in the length direction of the zero. The two connecting pieces 12 can be flexibly deformed, and a hook portion 12A is formed at a tip end thereof so that they can be elastically locked to the molding side locking portion 8. The coupling state with the locking portion 7 can be maintained. Further, a pair of deflection control walls 14 (corresponding to a deflection control portion of the present invention) are provided on both ends of the substrate 9 so as to face each other. A relief surface 15 is formed by being cut off obliquely at both upper corners of both deflection control walls 14. The relief surface 15 plays a role of avoiding interference with both arm portions 16 to be described later and facilitating entry between the both locking claws 17 of the molding side locking portion 8 (between the both arm portions 16).

The molding-side engaging portion 8 is formed to have substantially the same length as the panel-side engaging portion 7, and has a rectangular frame-like base portion 18 which is opened vertically at the center thereof. The stud bolt S can be accommodated in the housing. As shown in FIG. 7, the base 18 is located between the two connecting pieces 12 described above. Further, the lower end of the base 18 and the two connecting pieces 12
Of the hook portion 12A is connected by a thin connecting edge 19, whereby the molding side locking portion 8 and the panel side locking portion 7 are connected to be integrated. . Further, the connection edge 19 is set to such a strength that it can be broken by an operation force when the molding side locking portion 8 is pushed into the panel side locking portion 7, and after the connection is broken, the base portion 18 is connected to both sides. It enters between the connecting pieces 12. Furthermore, the connecting piece 12 is formed on the outer surface of the base 18.
A step 20 that can be engaged with both hook portions 12A
Are formed over the entire width.

The base 18 has a pair of flat plate-like arms 16 extending along both longitudinal directions (the same direction as the length of the molding M). The opposing arms 16 can be bent and deformed in a direction approaching each other, and the gap between the arms 16 is formed to be the same as or slightly larger than the width of the panel side locking portion 7. The panel side locking portion 7 can be accommodated between the opposed arm portions 16. Further, locking claws 17 which can be elastically locked to the corresponding flange edges F1 and F2 in the molding M are protruded from the outer surface of the distal end of each arm portion 16. The interval between the tips of the opposing locking claws 17 is formed to be larger than the opening width of the molding M (the distance between both side pieces 4). In this connection, the upper surface of each locking claw 17 is a guide surface 17A, and when the molding side locking portion 8 is pushed into the molding M, the respective locking claw 17 is brought into contact with the corresponding side piece 4. Can be smoothly bent and deformed. Conversely, the lower surface of the locking claw 17 becomes a substantially horizontal surface 17B, and the corresponding flange edge F
1, F2 can be engaged in a surface contact state.

Next, the first embodiment configured as described above.
The function and effect of the embodiment will be described specifically. First, the clip C is attached to the groove 1. That is, the through hole 1
The substrate 9 is brought into close contact with the bottom surface of the groove portion 1 while passing the head portion S2 of the stud bolt S through the zero insertion portion 10A. afterwards,
The entire clip C is slid to move the stud bolt S from the loose insertion portion 10A to the engagement portion 10B. During this time,
The stud bolt S flexes and deforms the pressing claw 11 and slides on the flange edge 13 to return to and engage with the stud bolt S when the movement to the engaging portion 10B is completed. Engagement of the portion S2 with the flange 13 prevents the stud bolt S from coming off, and engagement of the holding claw 11 with the head S2 of the stud bolt S prevents detent from returning to the play insertion portion 10A. Done. Thus,
The clip C is fixed to the roof panel, and the same procedure is repeated for each stud bolt S to mount the plurality of clips C in the groove 1.

Next, as shown in FIG. 3, the lower surface side opening of the molding M is fitted to the upper portion of the clip C while the molding M is along the groove portion 1, and the molding M is pushed in as it is. With this pushing, the opposing arm portions 16 are bent and deformed in a direction approaching each other, so that each locking claw 17 enters between the side pieces 4 of the molding M. Then, each locking claw 17 passes through the side piece 4 and the molding M
When the inner space reaches the inner space, it elastically returns to engage with the corresponding flange edges F1 and F2.

After the mounting of the molding M on the molding side locking portion 8 is completed, the molding side locking portion 8 is pushed down together with the molding M (see FIG. 4). By the pushing force at that time, the connection edge 19 connecting the molding side locking portion 8 and the panel side locking portion 7 is broken, and the connection relationship between the locking portions 7, 8 is cut off. For this reason, the panel side locking part 7 is accommodated between the corresponding arm parts 16. At this time, both the bending restricting walls 14 gradually break into the corresponding locking claws 17. If the lower end of the arm portion 16 is pushed until the lower end of the arm portion 16 reaches the bottom surface of the groove portion 1, the two connecting pieces 12
Hook portion 12A is engaged with the step 20 of the molding side locking portion 8, and the deflection control wall 14 enters the position between the hook portions 12A to almost the same height.

Thus, the mounting of the molding M is completed in the state shown in FIG. 5, but in this state, the deformation of the arm portion 16 in the disengagement direction (direction of approaching each other) is regulated, The situation in which 17 is dissociated from the flange edges F1 and F2 of the molding M can be reliably avoided. Therefore, even if the roundness of the flange edges F1 and F2 becomes large and the hooking with the locking claw 17 is reduced for reasons of manufacturing or the like, the flange edges F1 and F2 are not easily dissociated, and the reliability of the mounting of the molding M is reduced. The nature increases.

Further, according to the first embodiment, when the molding M is pushed into the clip C, the arm portion 16 can be freely bent and deformed, and is engaged with the tip of the arm portion 16 provided in a cantilever shape. Because the claws 17 are provided,
The bending deformation of the arm portion 16 is easily performed. Therefore, the effect that the molding M can be attached to the clip C with a light operating force is also exerted. Embodiment 1
In the above, the case where only the bending of the arm portion 16 is performed is shown, but the bending of the connecting piece 12 may also be controlled. For example, such a bending restricting means may be set in the molding side locking portion 8 so that the bending restricting action is exerted in the process of connecting the locking portions 7 and 8.

Embodiment 2 FIGS. 8 to 11 show Embodiment 2 of the present invention.
In the second embodiment, the molding side locking part 8 and the panel side locking part 7 are separated and formed separately. Panel side locking part 7
Are formed in the shape of a rectangular frame that opens up and down, and projecting edges 21 are formed at the lower end edges on both long sides thereof, thereby contributing to stabilizing the posture of the clip C with respect to the bottom surface of the groove 1.
In addition, a pair of locking recesses 22 for connection with the molding-side locking portion 8 are formed in the center of the side surfaces on both long sides of the panel-side locking portion 7. However, an inclined surface 23 having an upward slope from the lower edge side is provided in the locking recess 22.
Are formed.

On the other hand, a through hole 10 through which a stud bolt S can be inserted is opened in the bottom surface of the panel side locking portion 7, and the opening edge thereof is formed as shown in FIG.
It becomes C and it is easy to receive the stud bolt S.
As shown in FIG. 9, half of the through hole 10 is a play insertion portion 10A into which the head S2 of the stud bolt S can be loosely inserted. The protruding engagement portion 10B is formed, and the flange edge 13 can receive the head S2 of the stud bolt S from below. Furthermore, from the short side of the loose insertion portion 10A, the engagement portion 10B
The holding claw 11 extends substantially horizontally toward the center. The tip of the holding claw 11 is bent so as to lift upward, and forms a holding portion 11A for holding the upper surface of the head S2 of the stud bolt S.

The molding-side engaging portion 8 is formed in a frame shape capable of accommodating the panel-side engaging portion 7, and when accommodated, the corresponding side wall surfaces of the engaging portions 7, 8 are almost in close contact. . In addition, a pair of locking claws 17 that can be flexibly deformed are provided on both long side portions of the molding side locking portion 8 to face each other. Both locking claws 17 are formed so as to be flexibly deformable by cutting two slits along the height direction from the upper edge.
The locking claws 17 can be elastically engaged with the corresponding flange edges F1 and F2, and the basic structure is the same as that of the first embodiment. However, a locking step 24 is formed on the inner side surface of each of the locking claws 17 so as to have a stepped shape.
Can be elastically engaged with the locking concave portion 22.

The pair of left and right ribs 2 having a predetermined height are provided at positions outside the two slits in the panel side locking portion 7.
5 project from each other. The rib 25 cuts into the covering portions of the side pieces 4 of the molding M when the molding side locking portion 8 is locked to the molding M, so that the displacement of the molding side locking portion 8 with respect to the molding M can be avoided. It has become.

Next, the operation and effect of the second embodiment will be specifically described.
Attachment of the molding side locking portion 8 to the molding M is performed. After the head portion S2 of the stud bolt S is passed through the loose insertion portion 10A of the through hole 10, the panel side locking portion 7 is slid along the groove portion 1 as it is. As a result, the head S2 of the stud bolt S rides on the flange 13 of the engaging portion 10B, slides on the flange, and deflects the holding portion 11A of the holding claw 11 upward. And stud bolt S
When the head S2 reaches the inner part of the engaging portion 10B, the pressing claw 11 returns, and the pressing portion 11A
At the same time as the head S2 of the stud bolt S
Hold down. This prevents the stud bolt S from coming out of the panel side locking portion 7 and returning to the play insertion portion 10A side.

On the other hand, the molding M
At the time of installation, the lower opening of the molding M is
And press it in. Then, both the locking claws 17 are bent inward and deformed and enter the inside of the molding M, and return when the locking claw 17 is located inside the flange edge, and respectively engage with the corresponding flange edge. At this time, each rib 2 of the molding side locking portion 8
Since 5 penetrates into the covering portion 3 of the corresponding side piece 4 of the molding M, the positioning of the molding side locking portion 8 with respect to the molding M is more reliably performed.

After that, the molding M on which the molding side locking portion 8 is mounted is pushed into the panel side locking portion 7.
At this time, since the panel-side engaging portion 7 projects from the groove portion 1 and is located at a position slightly higher than the surrounding panel surface (upper surface of the roof panel), it is easy to set the target of the pushing. Then, when the molding side locking portion 8 is pushed in, the panel side locking portion 7 enters into the inside of the molding side locking portion 8, and the locking step portions 24 engage with the corresponding locking concave portions 22. And the two locking portions are connected to each other. Further, when the both locking portions are in the connected state, the panel side locking portion 7 is located between the both locking claws 17 so that the locking claws 17 are located.
In order to restrict the bending deformation in the disengagement direction, the engagement with the molding M is reliably maintained. The present invention can be variously modified, and the following modifications are also included in the technical scope of the present invention. That is, in the present embodiment, the fixing method using the stud bolts S for fixing to the roof panel has been described, but instead, the panel side locking portion 7 may be bonded with a double-sided tape.
