Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in a fixing structure for fixing a door trim to an inner panel of an automobile door.

[0002]

[Prior Art]

 Conventionally, when fixing a door trim to an inner panel of an automobile door, the peripheral side of the door trim is usually fixed by using a trim clip composed of a head and elastically deformable legs, and a central portion of the door trim is fixed. As shown in Japanese Utility Model Publication No. 3-8756, the side is fixed by also using the fixing means of the armrest. That is, although not specifically shown, the fixing of the central portion side is such that a mounting hole for engaging a screw grommet is formed in a corresponding portion of the inner panel, and a screw member is inserted through each of the armrest and the door trim. A hole is formed, and the tip of the screw member is screwed into the inside of the screw grommet from the insertion hole on the armrest side through the insertion hole on the door trim side to fix the armrest to the door trim. The center part of the door trim is fixed to the inner panel. Therefore, this fixing structure by joint tightening can be used not only as a means for fixing the door trim to the inner panel and a means for fixing the armrest to the door trim, but also to firmly fix each member to the corresponding member with a screwing force. It has the advantage of being fixed.

[0003]

[Problems to be solved by the device]

 However, under such a conventional fixing structure, when it is necessary to remove the door trim from the inner panel in order to inspect and repair various devices installed inside the automobile door, On the other hand, the fact is that the co-tightening structure that uses this screw member is damaged and the workability is significantly reduced. That is, in the conventional case, when the door trim is removed, it goes without saying that the trim clip fixing the peripheral edge of the door trim is removed from the inner panel. The door trim cannot be completely removed from the inner panel unless the screw member is removed to release the joint tightening state between the armrest and the door trim, which makes removing the door trim troublesome. In addition, when fixing the removed door trim to the inner panel, the armrest and the door trim must be tightened again, and even in this case, there are similar problems in work. ..

Further, in the related art, when the armrest is screwed to the door trim by using a screw member, the head of the screw member is exposed to the outside from the insertion hole of the armrest, which impairs the appearance. In addition to this, in order to prevent this, the above-mentioned insertion hole must be closed with a cap or the like, and this is also regarded as a problem.

[0005]

[Means for Solving the Problems]

 The fixing structure of the present invention was developed in order to effectively solve such a conventional problem. Based on the idea of previously integrating the armrest with the door trim, the metal clip for holding the door trim side, and the inner panel. The metal clip has a leg part that is elastically engaged in the insertion hole of the bracket provided on the back side of the door trim side and a flange part that is assembled to the screw grommet. The screw grommet has a leg portion that expands outward by screwing in a screw member and a head portion that slidably fits the flange portion of the metal clip from one direction. When is moved in the other direction, the flange part of the metal clip comes off the head of the screw grommet.

[0006]

[Action]

 Therefore, according to the present invention, the leg portion of the screw grommet is inserted into the mounting hole on the inner panel side, the screw grommet is screwed in to fix the screw grommet itself to the inner panel, and then the flange of the metal clip is attached. When the part is fitted to the head of the screw grommet from one direction, the metal clip can be easily assembled to the head of the screw grommet, so that while supporting the door trim that integrates the armrest, When the leg part of the metal clip is inserted into the insertion hole of the bracket on the door trim side, the leg part of the metal clip elastically engages with the hole edge of the insertion hole. In this state, the part of the door trim where the bracket is installed is securely fixed to the corresponding part of the inner panel. Therefore, finally, as in the conventional case, if the peripheral portion of the door trim is fixed to the inner panel by using the trim clip, the door trim is finally fixed to the inner panel.

When it is necessary to remove the door trim from the inner panel in order to inspect or repair various devices provided inside the automobile door, first remove the peripheral portion of the door trim. If you remove the trim clips that are fixed and lift the entire door trim in the other direction while keeping it as it is, the metal clips also keep their legs attached to the bracket insertion holes. Since it moves in the other direction along the head of the screw grommet and is easily released from the head of the screw grommet, it does not require the complicated work of releasing the joint tightening state of the armrest and the door trim as in the conventional case. The door trim can be easily removed from the inner panel.

【Example】

 Hereinafter, the present invention will be described in detail with reference to an illustrated embodiment. In the fixed structure according to this embodiment, a trim clip similar to the conventional one is used for fixing to the inner panel with respect to the peripheral portion of the door trim. However, regarding the center part, the armrest is integrated with the door trim in advance, and the part of the armrest or the part near the armrest is organically connected to the metal clip and the screw grommet described below. It is characterized in that it is used for fixing to the inner panel.

To explain this concretely, as shown in FIG. 1, the former metal clip 1 is integrally formed of a metal plate and has a leg portion 2 having an inverted U shape and a flange portion 3 having a U shape. With respect to the leg portion 2, an elastic locking piece 4 is formed on both side walls 2a, 2a defining an inverted U-shape, the tip end portion of which protrudes outward, When the inverted U-shaped leg portion 2 is inserted into the insertion hole of the bracket provided on the door trim side which will be described later, the tips of the elastic locking pieces 4 are elastically attached to the hole edges of the insertion hole. As a result, the door trim that integrates the armrests can be securely held from the rear surface side, and the flange portion 3 has both side walls 3a and 3a that define a U-shape. And bend the curved side walls 3a, 3a to the head of the screw grommet described later. While being configured to be slidable from above, a stopper piece 5 that bends inward is integrally extended to each side wall 3a, and the flange portion 3 is screwed by the action of each stopper piece 5. The grommet is configured so that it can be reliably assembled to the head without falling off from the head.

On the other hand, the latter screw grommet 11 is an integrally molded product made of synthetic resin, and has a fork-shaped leg portion 12 that expands outward by screwing the screw member and a flange portion of the metal clip 1. 3 has a head part 13 that is slidably fitted on the outside, and in particular, as shown in the figure, the head part 13 is formed into a quadrilateral shape as a whole, and one facing side part is formed as described above. The flange 15 is not provided with the guide wall 14, and the recesses 15 for locking the stopper pieces 5 are formed at the other opposing sides.

Further, in this embodiment, as shown in FIG. 2, a part of the armrest 22 is screwed to the door trim 21 from the back side via the screw member 23, and the armrest 22 is attached to the door trim 21. In addition to being integrated in advance, a bracket 24 having an insertion hole 25 into which the leg portion 2 of the metal clip 1 is inserted is separately or integrally provided on the rear surface side of the armrest 22, and the bracket 24 is attached to the door trim 21. A structure is adopted in which the opening 26 provided on the side faces the rear side. In addition, in this case, in the drawing, for convenience, one end of the armrest 22 is integrated with the door trim 21 by a single screw member 23, but the other end of the armrest 22 may be used as necessary. Of course, the number of brackets 24 provided on the armrest 22 is not limited to one, although it is needless to say that the other portions are screwed.

Therefore, when fixing the door trim 21 in which the armrest 22 is integrated to the inner panel 27 of the automobile door, first, as shown in FIG. 3, the leg portion 12 of the screw grommet 11 is attached to the inner panel 27. The leg portion 12 is expanded outward by inserting the screw member 29 into the mounting hole 28, and the screw grommet 11 itself is fixed to the inner panel 27.

Then, when the stopper piece 5 described above is maintained in the posture in which the stopper piece 5 is positioned above, the flange portion 3 of the metal clip 1 is slid onto the head portion 13 of the screw grommet 11 from above to be fitted externally. As shown in FIG. 4, each stopper piece 5 is locked in the recessed portion 15 formed in the head portion 13 so that the flange portion 3 of the metal clip 1 is easily assembled to the head portion 13 of the screw grommet 11. In the assembled state of the metal clip 1, the metal clip 1 never falls downward from the head 13 of the screw grommet 11 due to the engagement of the stopper piece 5 with the recess 15. However, under this state, if the metal clip 1 is moved upward, the flange portion 3 of the metal clip 1 can be easily removed from the head portion 13 of the screw grommet 11.

Therefore, after the assembled state of the metal clip 1 is obtained, when the leg portion 2 of the metal clip 1 is inserted into the insertion hole 25 of the bracket 24 while supporting the entire door trim 21, the metal clip 1 is attached. Since the leg portion 2 of 1 passes through the insertion hole 25 while bending the elastic locking piece 4, the tip end of each elastic locking piece 4 is elastically attached to the hole edge of the insertion hole 25. As a result, the door trim 21 is held by the metal clip 1, and as shown in FIG. 5, the central portion of the door trim 21, that is, the armrest 22 is integrated with the door trim 21 and secured to the inner panel 27. Fixed to. Therefore, finally, although not specifically shown, if the peripheral portion of the door trim 21 is fixed to the inner panel 27 using a trim clip as in the conventional case, the door trim 21 in which the arm rest 22 is integrated becomes It will be finally fixed to the inner panel 27.

Further, in this embodiment, when the armrest 22 is integrated with the door trim 21, a structure is adopted in which both 21 and 22 are screwed from the back side thereof via the screw member 23. Unlike the conventional co-tightening and fixing structure, there is no concern that the head of the screw member 23 is exposed to the outside, and there is no concern that the appearance will be impaired. It should be noted that the integration of the armrest 22 is not limited to the screw member 23, and other means can be appropriately used as long as they do not impair the appearance, and the armrest 22 is formed integrally with the door trim 21. You may.

Then, in the case where it is necessary to remove the door trim 21 from the inner panel 27 in order to inspect or repair the device provided inside the automobile door, this embodiment is carried out. In that case, first, by removing all the trim clips fixing the peripheral portion of the door trim 21, and lifting the entire door trim 21 upward in the state as it is, the metal clip 1 and the leg portion 2 of itself are also removed. While being attached to the insertion hole 25 of the bracket 24, it moves upward along the head 13 of the screw grommet 11 and easily comes off the head 13 of the screw grommet 11. It can be easily removed from the inner panel 27. That is, in the present embodiment, first, the trim clip is removed in the same manner as the conventional structure, but thereafter, the screw member 29 screwed into the leg portion 12 of the screw grommet 11 is removed. Even if it is not necessary, the door trim 21 can be easily removed from the inner panel 27 by simply lifting the entire door trim 21 upward, and this can greatly improve workability.

When fixing the removed door trim 21 to the inner panel 27 again, the leg portion 2 of the metal clip 1 is pulled out from the insertion hole 25 of the bracket 24, and the flange of the metal clip 1 is pulled out. The door trim 21 can be easily fixed to the inner panel 27 by assembling the portion 3 to the head portion 13 of the screw grommet 11 fixed to the inner panel 27 and following the same procedure as above.

In the above embodiment, the bracket 24 is provided on the armrest 22 integrated with the door trim 21, and the armrest 22 is fixed as the central part of the door trim 21. Is not limited to this, and a bracket 24 is provided near the armrest 22 of the door trim 21 itself, and the central portion of the door trim 21 itself is fixed to the inner panel 27 by using the bracket 24. In addition, the number of metal clips 1 and screw grommets 11 used for this fixing is appropriately determined depending on the size and weight of the door trim 21.
