Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a molding holder for mounting a molding to a panel such as a vehicle body.

[Conventional technology]

A resin molding retainer used to attach a molding between the peripheral portion of the windshield glass of an automobile and the vehicle body is such that the shaft portion of the grommet portion is inserted into the mounting hole formed in the panel of the vehicle body or the like. , Furthermore, screw in the screw parts to expand the shaft part of the grommet part radially outward,
Some get a bond with the panel. One of them is that a locking step is formed on the outer surface of the grommet part shaft part, and when the shaft part is expanded radially outward by a screw part, this step part engages with the back side of the vehicle body panel. There are some that get stuck. In this type of molding holder, since the mounting is easy, the locking step of the shaft of the grommet cannot be made too high. Therefore, even when the shaft portion is expanded, a sufficient height for locking cannot be provided between the step portion and the panel, and there is a problem that the locking holding force is weak.

As a structure capable of solving the problem of the holding force, a grommet has been devised which includes a grommet shaft portion and a nut piece that is drawn into the shaft portion hole and expands the shaft portion radially outward. In this type of grommet, the shaft part is divided into a plurality of legs by slits, etc., the nut piece has a shaft hole that engages with the screw part, and the nut part is rotated by rotating the screw part. Pull into the hole to expand. Therefore, by appropriately determining the outer surface shape of the nut piece and the inner surface shape of the grommet shaft portion, the expansion amount of the leg portion can be determined, so that it is possible to design the locking height to be sufficient and to retain the locking holding force. Can be stronger

[Problems to be solved by the device]

Of the above two types of grommets, the former type has the grommet shaft part inserted into the panel hole, and then the screw such as the tapping screw is rotated with one hand and the other hand with the grommet. Must be supported and workability is extremely poor. However, if the screw is attached to the grommet shaft portion first, the shaft portion expands, and the grommet cannot be attached to the panel.

On the other hand, in the latter type of grommet, the locking height can be made sufficiently high, and a screw may be attached in advance so long as the shaft portion does not spread, and a problem in workability can be eliminated.
However, this type of grommet can be fixed to the panel with a comparatively strong force in the state of temporary assembly with the screw attached first, so it will be left as it is and forget the screwing work for fixing. In this temporarily assembled state, the nut piece is separated from the grommet shaft, so the vehicle body hole cannot be sealed liquid-tight and water such as rain that hits the windshield glass leaks into the room. There was a problem that came.

Therefore, an object of the present invention is to provide a molding holder that can obtain a temporarily assembled state and can prevent water such as rain from entering the room even in the temporarily assembled state.

[Means for Solving the Problems]

In order to solve the above problems, the present invention comprises a grommet portion held by a panel of a vehicle body and a molding holding portion for locking and holding the molding, and a member such as a tapping screw can be inserted into the grommet portion. A molding holder in which a hole is formed and a grommet portion can be firmly attached to a panel by inserting the member, wherein the grommet portion and the molding holding portion are configured as separate components, and both components are mutually predetermined. So as to be assembled in the form of a molding holder, concave portions and convex portions are formed on the surfaces facing each other, and the molding holding component further includes a base portion on which concave portions or convex portions for receiving the grommet portion are formed. A cylindrical shaft portion that is formed so as to project from the base portion and that can be inserted into the hole of the shaft portion of the grommet part and that has a hole through which a member such as the screw penetrates in the center, and the concave portion and the convex portion. When the members such as the screws are inserted in a state in which the shaft portion of the molding holding component is inserted into the shaft portion of the grommet component, it is possible to obtain a temporary assembled state with a certain interval, and in this temporary assembled state When the shaft part of the grommet part is inserted into the panel hole and the shaft part of the grommet part is inserted into the panel hole, the entire holder can be locked to the panel, and the members such as the screws are attached. When further inserted, the molding holder is configured such that the molding holding component shaft portion is inserted to a position where the diameter of the grommet shaft portion is expanded and firmly attached to the panel.

[Action]

The molding holder of the present invention can be temporarily assembled at the time of manufacturing or during distribution by inserting a member such as a screw into the grommet part and the molding holding part by a predetermined depth, and in this state, The shaft portion of the grommet member does not expand, and the entire mall holder is inserted into the vehicle body hole in the vehicle body panel or the like for temporary assembly. Therefore, since all the components necessary for mounting the molding holder are preassembled, the mounting work on the vehicle body panel or the like can be performed very easily.

In this final fastening, the molding is attached to the molding holding component, and then a member such as a screw is further inserted. As a result, the shaft portion of the grommet component expands outward in the radial direction, and the shaft portion of the grommet component is firmly held so as not to swell and fall off on the back side of the mounting side component such as the vehicle body panel.

As described above, the molding 29 with the molding holder is arranged so as to cover the gap between the windshield glass 31 and the vehicle body panel 32, and the shaft portion 17 of the grommet part 15 of the molding holder is applied to the hole 33 of the panel 31. Then, insert it with your finger etc. and temporarily fix it. As described above, this temporary fixing can be performed with a weak force such as a finger because the locking step portion 18 of the grommet component is bent inward.

As shown by the imaginary line, turn the flap 30 over the mall holder in the temporarily fastened state, put the tip of the screwdriver 34 on the tapping screw 27, and rotate the screwdriver 34 by hand or electrically to rotate the tapping screw 27. The gap x between both parts is set to zero. As a result, the shaft portion 10 of the molding holding component is pushed into the shaft portion 17 of the grommet component, the locking step portion 18 outside the shaft portion 17 is expanded outward, and the molding holder is firmly fixed to the panel 32. Book it. After this book fastening, the flap 30 is released to restore the original state shown by the solid line.

At the time of this final fastening, even if the overall curvature of the windshield glass 31 does not match the curvature of the molding 29 and there is a large gap at both ends of the molding, the molding holding parts in the temporarily assembled state Since there is a space x between the molding 1 and the grommet component 15, the molding holder according to the present invention can be temporarily fixed even at the end of the molding without the reaction force of the molding being applied. Therefore, when the tapping screw 27 is tightened for final fastening, the bending of the molding 29 can be matched with the bending of the shield glass 31, and the molding 29 does not float.

When the molding retainer is removed, the flap 30 is flipped over in the state shown in FIG. 4 and the tapping screw 27 is rotated in the returning direction to disconnect the molding holding component 1 and the grommet component 15. That is, by removing the tapping screw 27 and pulling the molding 29 upward in FIG. 4, the molding holding component 1 can be removed from the grommet component 15.
