Description

[Detailed description of the invention] (Industrial application field) This invention relates to a door molding (hereinafter, simply referred to as a molding) that closes a gap between a door panel and a door glass of an automobile.
And a clip for attaching the same.

(Prior Art) FIG. 7 shows an example of this type of clip. The clip C 'has a flange locking piece 40 and a holding piece 41 as a molding bonding means, and the molding M is mounted by engaging with the mounting edge 42 or the insertion edge 43 of the molding M, respectively. be able to. The clip C 'is inserted into an insertion hole 45 opened in the door panel 44 in a state where the clip C' is attached to the molding M, and the insertion piece elastically engages the retaining piece 46 with the step edge 47 of the door panel 44. In this way, the entire clip C 'is prevented from coming off.

(Problem to be Solved by the Invention) Incidentally, after the molding M is attached to the door panel 44, it may be necessary to remove the molding M. In this case, an appropriate tool 48 is used to pry the space between the mounting edge 42 of the molding M and the door panel 44 and lift the same as it is. By doing so, the engagement of the retaining piece 46 is forcibly released, and the molding M is removed with the clip C 'attached.

However, since an unreasonable force (for example, a force in the direction of pushing up the step edge 47) is applied to the retaining piece 46 by the above-described removal operation, the retaining piece 46 may be broken from the base portion. The broken retaining piece 46 falls into the door and remains, which causes abnormal noise when the door is opened and closed. Therefore, it must be removed, but must first be removed from the door lining, and since the interior space of the door is dark and narrow, it is very troublesome from discovery to removal.

The breakage of the retaining piece 46 may occur not only when the molding M is removed but also when the molding M is attached to the door panel 44 side.

Further, in the related art, the rigidity of the retaining piece 46 is often set to be slightly higher than to enhance the retaining force of the clip C. Therefore, before the engagement of the retaining piece 46 is released, a considerable force is applied to the molding M to lift or twist the molding M. Therefore, the deformation is likely to occur particularly in the portion near the tip of the insertion edge 43. For this reason, the mall M from which the corners can be removed is often not reusable.

In view of these problems, the present invention aims to obtain a door molding clip that can prevent the generation of abnormal noise by preventing the retaining piece from falling off even if the retaining piece is broken. Another object of the present invention is to provide a clip that enables the mall to be reused.

(Means for Solving the Problems) According to the structure of the present invention for achieving the above object, a part of a substrate having a mounting means for mounting a molding has a tip engaged with a door panel side. A clip for a molding in which a retaining piece for retaining the entire clip is formed so as to be able to bend and deform so as to prevent the retaining piece from falling off from the substrate side when the retaining piece is broken. The retaining piece and the substrate side are connected by a connecting piece. Further, for the reason described later, it is preferable to form a thinned portion at the base of the retaining piece for promoting breakage of the retaining piece.

(Operation) According to the clip configured as described above, even when the retaining piece is broken when the molding is removed from the door panel or attached to the door panel, the retaining piece is connected to the connecting piece. Since it is tied to the substrate side, it is possible to avoid a situation of falling into the door. Also, if the root of the retaining piece is removed, the retaining piece can be broken and released from engagement with the door panel before the molding is deformed when the molding is removed.

(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an attached state of the molding M, and FIG.
Is an outer door panel (hereinafter, simply referred to as a door panel) that forms a door together with an inner door panel (not shown), and a door glass G is disposed between the inner door panel and the inner door panel so as to be able to move up and down. The door panel 1 shown in the figure is composed of two inner and outer panels 1a and 1b, and is of a type in which the outer upper edge is hemmed and bonded by welding or the like. A clip insertion hole 2 is opened at an appropriate interval at an upper portion of the inner panel 1b, and a retaining piece 4 described later engages with a height position corresponding to the clip insertion hole 2 on the outer panel 1a. The step edge 3 is formed stepwise.

The molding M is mainly composed of the cored bar 5, and a portion that covers the upper surface of the door panel 1 (decorative edge 6) and a portion that is inserted into a gap between the door panel 1 and the door glass G (insertion edge 7).
And more. Then, a soft resin coating is applied from a part of the decorative edge 6 to the lower end of the insertion edge 7, and the lip 8 has good flexibility and adheres to the door glass G from the insertion edge 7. Is overhanging in two steps. In addition, the lower end of the insertion edge portion 7 is slightly bulged due to the hemming of the metal core 5, and as a result, the bulging portion 9 is formed so that the claw edge 10 of the clip C described later can be engaged. It has become. On the other hand, the front end side of the decorative rim 6 of the molding M is bent inward to form a flange rim 11, where a close rim 12 is formed by covering with a soft resin and is in close contact with the upper surface of the door panel 1.

Next, the configuration of the clip C will be described. The clip C is integrally formed of a synthetic resin material and has a substrate 13 that can be inserted into the clip insertion hole 2. As shown in FIG. 1, the substrate 13 can contact the inner surface of the outer panel 1a and the outer surface of the inner panel 1b of the door panel 1 above and below the clip insertion hole 2, respectively. Further, a rectangular window 14 is opened at the center of the substrate 13. And, as described below,
In 13, mounting means for mounting the mall M is set.

On the surface of the substrate 13 facing the door glass G,
A pair of holding pieces 15 that can be expanded and deformed are arranged on the left and right sides of the window portion 14 so that the insertion edge 7 of the molding M can be held between the holding piece 15 and the substrate 13. A claw edge 10 that elastically engages with the bulging portion 9 is formed at the tip end of 15. A protruding edge 16 is formed to protrude over the entire width of the upper surface of the substrate 13 facing the door glass G so as to hit the inner surface of the insertion edge portion 7. Further, a pair of projecting edges 17 are formed on both sides of the window portion 14 so as to protrude vertically in a range from the overhanging edge 16 to the bottom surface in the holding piece 15. However, the protruding height of the two protruding edges 17 is set lower than the overhanging edge 16. The reason why the above-mentioned overhanging edge 16 and both protruding edges 17 are provided is to reduce the thickness of the substrate 13 for the purpose of reducing the material constituting the clip C and to suppress the rattling of the molding M in this case. M is held down from behind.

On the other hand, a pair of flange locking pieces 18 for engaging with the mounting edge 6 side of the molding M are provided on both left and right sides of the upper edge of the substrate 13.
Are formed in the opposite direction to the door glass G. The two flange locking pieces 18 are allowed to bend downwardly, and each end has a locking claw that engages with the flange edge 11.
19 are formed.

Next, the means for fixing the clip C to the door panel 1 will be described. A pinching piece 20 that can be flexibly deformed independently extends from between the two flange locking pieces 18 of the board 13 and extends downward. 13 and an insertion groove 21 having a U-shaped cross section which can be expanded to hold an upper edge portion of the door panel 1 therebetween. In order to facilitate insertion of the holding piece 20 into the door panel 1, the lower portion is slightly curved and the entrance side of the insertion groove 21 is widened. In order to reinforce this upward warped portion, a rib 22 is formed in a longitudinal direction at a central portion on the surface side of the holding piece 20. On the other hand, a tapered guide tongue piece 23 is formed continuously below the substrate 13. The guide tongue piece 23 is formed in a slightly upwardly warped shape on the side opposite to the door glass G, and has a smooth curved back surface. The guide tongue 23 plays a role of guiding the clip C into the insertion hole 2 by slidingly contacting the edge of the hole when the guide tongue 23 is inserted into the clip insertion hole 2.

A retaining piece 4 is formed upright from the lower opening edge of the window portion 14 to restrict the clip C from coming off upward. The retaining piece 4 is formed so as to project obliquely upward to the side opposite to the door glass G, and is allowed to bend in the upright direction. Also, at the tip of the retaining piece 4, a retaining claw that can be engaged with the stepped edge 3 of the door panel 1.
24 are formed.

Note that the retaining claw 24 is provided with rigidity so that the necessary minimum removal force of the clip C with respect to the door panel 1 can be obtained. However, as described above, the molding M is not deformed as the clip C is removed. The settings are such that they break at the previous stage.

Further, the retaining piece 4 is connected to the substrate 13 by a connecting piece 25 on the surface side so that the retaining piece 4 does not come off from the clip C even when the retaining piece 4 is broken. Connection piece 25
Are arranged vertically in a thin string shape, and a loosened portion 25a is set at the connection end on the substrate 13 side, so that the retaining piece 4 is also bent so that it does not easily break itself. You can follow well.

Note that the connection piece 25 may be arranged horizontally or
It may be arranged on the back surface of the substrate 13, that is, the position of the substrate 13 can be changed as long as it can be prevented from falling off from the substrate 13 side.

The operation and effect of the clip of the present embodiment configured as described above will be described. When the clip C is mounted on the molding M, the insertion edge 7 of the molding M is inserted into both holding pieces 15 so that the claw edge 10 is inserted. And the bulging portion 9 is engaged. By this insertion, both flange locking pieces 18 are pressed and bent by the decorative edge 6 of the molding M, and these locking claws 19 are engaged with the flange edge 11, respectively. Thus, the clip C is mounted on the molding M.

Subsequently, mounting to the door panel 1 is performed in the above-described pre-attached state. First, the guide tongue piece 23 of the clip C is positioned between the door panel 1 and the door glass G, and is pushed downward as it is. In this case, the clip C is a guide tongue.
The tip end of the guide tongue piece 23 is pressed straight down while the tip end of the guide panel 23 is in contact with the wall surface above the clip insertion hole 2 in the door panel 1, and the lower surface of the guide hole 23 contacts the lower opening edge of the clip insertion hole 2 when pressed down. When the clip C is further pushed down, the clip C is automatically guided to the inside of the clip insertion hole 2 under the guidance of the curved surface on the back surface of the guide tongue piece 23. Therefore, the work of inserting into the insertion hole 2 which cannot be seen directly by the operator becomes easy. On the other hand, the upper edge of the door panel 1 enters while expanding the insertion groove 21, and is held by the holding pieces 20 and the substrate 13. During this time, the retaining piece 4 comes into sliding contact with the wall surface of the door panel 1 while flexing and deforming, and the retaining claw 24 and the step edge 3 engage when the insertion of the clip C is completed. Thus, the clip C is assembled in a retaining state, and the molding M
Is fixed to the door panel 1.

By the way, if it becomes necessary to remove the molding M after fixing it, an appropriate tool should be attached to the flange edge of the molding M.
Measures are taken to dive below 11 and lift as it is.
As a result of this work, as described above, the retaining piece 4 is strongly pressed against the step edge 3 and receives a counterclockwise reaction force in FIG. 1, so that the retaining piece 4 may be broken from the base portion. is there. However, even when the retaining piece 4 is broken, as shown in FIG. 5, the connecting piece 25 is tied up to prevent the falling off, so that the generation of abnormal noise in the door panel 1 is prevented. Can be.

In this example, although the rigidity of the retaining piece 4 is set so as to secure the minimum necessary withdrawal force,
The setting is such that it can be easily broken than before. Specifically, the setting is such that when the molding M is detached, the molding M is broken by the time when the molding M is deformed. If the retaining piece 4 is broken, the clip C can be pulled out of the door panel 1 together with the molding M, so that the molding M can be removed without deformation and the molding can be reused.

As means for promoting breakage of the retaining piece 4 as described above, it is also effective to remove the thickness of the base portion of the retaining piece 4 as shown in FIG.

(Effects of the invention) The effects of the invention are as follows.

Even if the retaining piece breaks when the molding is removed or when the clip is inserted, the falling off piece is avoided by the connecting piece. Can be eliminated.

In addition, if the retaining piece is set to be broken before the molding is deformed when the molding is removed, the molding can be taken out as it is, so that it can be reused and the economy is improved. .
