The screw 4a is inserted and fastened and fixed to the mounting hole 3a of the door inner panel 3, so that the door grip 2 is firmly fixed to the door inner panel 3.

In order to cover the upper and lower mounting portions of the door grip 2, an inside handle escutcheon 5 is provided.
And a decorative cap 6.

[0005]

As described above, in the conventional door grip 2, the decorative cap 6 gives a sense of incongruity, and the dividing line between the door grip 2 and the inside handle escutcheon 5 is conspicuous. It was pointed out that the problem was caused.

Further, since the door grip 2 has a structure in which the core material 2a is inserted into the pad material 2b and the outer surface of the pad material 2b is covered with the skin material 2c formed by slush molding, the manufacturing cost is high, and At the same time, it has been pointed out that the number of man-hours for mounting the door trim 1 and the door panel 3 becomes large, resulting in a significant increase in cost.

The present invention has been made in view of such circumstances, and in a door grip structure which is installed in a grip shape at a predetermined position on the surface of a door trim, the appearance design is improved, and the manufacturing cost and the mounting cost are reduced. It is an object of the present invention to provide a door grip structure that can reduce the cost.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention comprises a grip base and a grip cover made of a resin molded body, and is installed at a predetermined position on the front side of a door trim in the form of a handle. In the door grip structure described above, the grip cover has an inside handle unit and an inside handle escutsion portion that covers an upper end mounting portion of the grip base integrally formed at an upper portion, and borders a grip insertion opening formed in the door trim. And a grip escutcheon for covering a joint portion between the door trim and the door grip is provided.

The grip base and the grip cover are made of injection-molded synthetic resin such as PP resin and ABS resin. The grip base and the grip cover are attached to both side flanges, and both are joined and fixed by nail engagement or the like. Then, a hollow door grip can be easily configured.

[0010] If a reinforcing rib extending vertically or horizontally is integrally formed on the inner surfaces of the grip base and the grip cover, desired strong rigidity can be obtained.

The grip base has upper and lower ends,
First, the grip is fixed to the inner surface side of the door trim, and then, when the door trim is mounted on the door inner panel, the grip base is firmly fixed to the door panel by fixing it to the door panel with screws or the like.

On the other hand, the grip cover is joined and fixed to the grip base by claw engagement or the like, and is inserted and fixed at the lower end thereof into the opening of the door trim, and the inside handle escutsion portion at the upper end is engaged and fixed to the inside handle unit. .

As is apparent from the above configuration, since the inside handle escutcheon portion is integrally formed at the upper end of the grip cover, a dividing line between the door grip and the inside handle escutcheon is not formed as in the conventional case. The decorative cap that covers the mounting opening can also be eliminated.

Further, since the opening edge of the joint portion between the grip base and the grip cover and the door trim is bordered by the grip escutcheon, there is no gap between the door trim and the door grip.

On the other hand, the door grip is for joining and fixing a grip base and a grip cover made of an injection-molded article, and a core material is inserted into a pad material, and the outer surface is covered with a slash-molded skin material. Configuration can be abolished.
