DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door grip mounting structure for mounting a door grip, in which a core material is inserted into a soft resin molded body, to a door trim.

[0002]

2. Description of the Related Art For example, as shown in FIG. 9, a door grip 2 having a handle shape is attached to the center of the surface of a door trim 1 provided in a door panel, and an occupant grasps the door grip 2 to open and close the door. The operation is being performed.

The structure of the door grip 2 and the mounting structure for the door trim 1 will be described with reference to FIG. 10. Since the door grip 2 requires a desired rigidity, a hard thermoplastic resin such as a polypropylene resin or a polyacetal resin is used. The surface of the core material 3 made of a resin molded body or a metal plate is covered with a skin material 4 made of a soft resin such as soft PVC. At the time of opening and closing the door, a good feeling when the door grip 2 is gripped is provided.

The door grip 2 is provided by inserting a core material 3 formed into a required shape into an injection molding die and injecting a resin such as soft PVC into the die to form a core core. It is mass-produced by the insert injection method in which the material 3 and the skin material 4 are integrated.

Further, the door grip 2 is connected to the door trim 1.
In addition, in order to attach to the door panel 5, an attachment boss 6 is formed on the back surface of the core core material 3 so that a screw 7 is inserted into the attachment boss 6 of the door grip 2. The door grip 2 is attached by being tightened and fixed in the mounting hole 5a. In order to improve the appearance of the mating surface between the door grip 2 and the door trim 1, and to prevent low sound absorption such as rubbing sound, A grip base 8 is inserted on the front side of the door trim 1.

Therefore, in order to align the mounting surface 2a of the door grip 2 with the door trim 1, as shown in FIG. 11, the grip base 8 located at a predetermined position on the surface of the door trim 1 is pressed from the front side. The attachment surface 2a of the door grip 2 is attached, and at this time, the periphery of the attachment surface 2a of the door grip 2 is fitted and fixed to the inner peripheral wall of the peripheral flange 8a of the grip base 8.

[0007]

As described above, when the door grip 2 is mounted on the door trim 1, the grip base 8 is inserted for the purpose of design and low sound absorption prevention. When fitting the mounting surface 2a of the door grip 2, as shown in FIG. 12, one side edge of the mounting surface 2a of the door grip 2 is locked to one side of the flange 8a of the grip base 8, and this is used as a base point. The actual situation is that the other side edge of the mounting surface 2a of the door grip 2 is mounted so as to be fitted to the opposite flange 8a.

Therefore, the mounting surface 2a of the door grip 2
And the inner wall of the flange 8a of the grip base 8 are set in close contact with each other, but it is preferable in terms of appearance. However, insertion work is difficult, and workability is deteriorated. There is a possibility that the appearance defect such as the terminal of the skin material 4 being rolled up may be caused.

The present invention has been made in view of such circumstances, and a door grip which can be easily and beautifully fitted and fixed to a door trim made of a soft resin molded body having a core core material inserted therein. The purpose of the present invention is to provide a mounting structure.

[0010]

In order to achieve the above-mentioned object, the present invention provides a handle-like door grip formed by inserting a core core material into a skin material made of a soft resin molded product, and a door trim surface. In the mounting structure of the door grip to be fitted on the door trim side by fitting the peripheral edge of the mounting surface of the door grip into the mounting seat surface installed on the side, the peripheral edge of the mounting surface of the door grip is given inward flexibility. Thus, the periphery of the mounting surface of the door grip is elastically fitted into the mounting seat surface on the door trim side.

As means for imparting inward flexibility to the periphery of the mounting surface of the door grip, an annular notch may be formed along the inside of the periphery of the mounting surface. Except for the above, other portions may be hollowed out, and flexible leg pieces may be protruded along the peripheral edge of the back surface of the mounting surface.

Further, the peripheral shape of the mounting surface of the door grip may be chamfered so as to be surface-connected to the flange of the mounting seat surface or the inner wall surface of the step portion.

[0013] As a mounting seat surface installed on the surface of the door trim, a grip base made of a resin molded body having a flange on the periphery may be attached to the surface of the door trim. The flange or the step portion may be integrally formed so as to protrude.

[0014]

As is apparent from the above configuration, since the periphery of the mounting surface of the door grip is given inward flexibility, when the door grip is mounted on the mounting surface of the door trim, the flange of the mounting seat surface is used. Alternatively, since the periphery of the mounting surface of the door grip fits closely to the inner wall surface of the step, the mounting surface of the door grip can be easily fitted and fixed in the mounting seat surface.

Further, if the mounting surface of the door grip is fitted and fixed to the mounting seat surface of the door trim, a repulsive force is generated at the peripheral edge of the mounting surface of the door grip, and the peripheral edge of the door grip mounting surface is formed in a flange or a step. It is urged in the direction of close contact with the wall.
