【Example】

 (Embodiment 1) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, 1 is a speaker grill which is an interior component, 2 is a frame member which is a component body, and 10 is a door trim.

The speaker grill 1 includes a frame member 2 formed by injection molding and a punching metal 3 fixed to the frame member 2 by induction heating or claw bending. The frame member 2 is integrally formed with a flange 4 on the outer periphery. The flanges 4 on both sides are provided with a plurality of fixing flanges 5 serving as locking projections and a plurality of stoppers 6. A hole 7 is provided in the fixed flange 5, and the hole 7 is positioned so that the spring wire 8 comes into close contact with the rear surface of the door trim 10 when a spring wire 8 which is an elastic member described later is inserted. .

An opening 11 for a speaker is provided in the door trim 10, and holes 12 and 13 through which the fixing flange 5 and the stopper 6 of the speaker grill 1 are inserted are provided on both sides of the opening 11.

When attaching the speaker grill 1 to the door trim 10, after inserting the fixing flange 5 and the stopper 6 into the holes 12 and 13 of the door trim 10, respectively, the holes 7 of the fixing flanges 5 on both sides are cross-sectioned from the outside. When the spring wire 8 shaped like a hook is hooked, the spring wire 8 comes into close contact with the rear surface of the door trim 10. At this time, the spring wire 8 is passed through the back side of the stopper 6 to fix the speaker grill 1 by utilizing the elasticity of the spring wire 8 and prevent the spring wire 8 from coming off.

As described above, the frame member 2 of the speaker grill 1 is provided with the fixing flange 5 that penetrates into the hole 12 of the door trim 10, and the hole 7 into which the spring wire 8 is inserted into the fixing flange 5 on the rear side of the door trim 10. By providing the stopper 6 for preventing the spring wire 8 from coming off from the frame member 2, the spring wire 8 can be inserted into the hole 7 of the fixed flange 5 and hooked on the fixed flange 5 to form the speaker grill 1. Since it can be mounted on the door trim 10, the mounting time can be shortened, the man-hours can be reduced, and the cost can be reduced. Further, since it is sufficient that the spring wire 8 is mounted in such a size, the H dimension shown in the conventional example can be small, and the h dimension protruding from the surface of the door trim can also be reduced.

In the above embodiment, the fixed flange 5 and the stopper 6 are provided on the flange 4 portion of the frame member 2, but as shown in FIGS. 3 (a) and 3 (b), the flange 5 and the stopper 6 are provided on the frame member. When projecting from the side of the main body 2a of 2, the holes 12 and 13 provided in the door trim 10 are hidden by the flange 4 portion of the frame member 2 and are not visible from the outside, which is a good appearance.

Further, the spring wires 8 were hooked in the holes 7 of the fixing flanges 5 on both sides, respectively. As shown in FIG. 4, one spring wire 8 was used to hook the holes 7 of the fixing flanges 5 on both sides to The side may be passed through the back side of the stopper 6.

Further, if the fixing flange 5 is provided with a notch 9 as shown in FIG. 5 instead of the hole 7, it is only necessary to hook the spring wire 8 into the notch 9 without passing through the hole. It's easy.

Further, the stopper 6 for preventing the spring wire 8 from coming off may be provided on the door trim 10 side (not shown).

The above-described invention can be applied to parts such as an air inlet other than the speaker, and can be attached not only to the door trim but also to a pillar or the like.

Second Embodiment A second embodiment of the present invention will be described below with reference to FIG. In the figure, 1 is a speaker grill which is an interior component, 2 is a frame member which is a component body, and 10 is a door trim. The above is the same as the configuration of FIG. 1 is different from that of FIG. 1 in that a flange 4 which is a locking projection is provided with a fitting hole 15 for fitting a spring wire 16 which is an elastic member, and the spring wire 16 is linear with a plurality of engaging parts 16a. 16 b and a plurality of stoppers 18 are provided on the inner surface of the door trim 10.

That is, fitting holes 15 are formed on both upper and lower sides of the flange 4 of the frame member 2 of the speaker grill 1, and the spring wire 16 has an engaging portion 16 a formed at a position facing the fitting hole 15. It is formed by connecting the engaging portion 16a with the linear portion 16b. Further, a plurality of stoppers 18 are formed on the upper and lower inner surfaces of the speaker opening 11 of the attrim 10, and the interval between the stopper 18 and the opening 11 is set to a size in which the spring wire 16 is fitted.

When the speaker grill 1 is attached to the door trim 10, when the flange 4 of the speaker grill 1 is fitted into the speaker opening 11 of the door trim 10 in the direction of arrow A from the front side of the door trim 10, the flange 4 is provided. The fitting hole 15 is exposed on the back surface side of the door trim 10. The engaging portion 16a of the two spring wires 16 is fitted into the fitting hole 15 from the outside of the flange 4 in the direction of arrow B, and at the same time, the linear portion 16b is pushed between the engaging portion 15a and the stopper 18.

At this time, the head portion of the engaging portion 16a of the spring wire 16 is exposed from the fitting hole 15, and the linear portion 16b is in contact with the edge of the speaker opening 11. Therefore, the engaging portion 16a of the spring wire 16 is fixed to the flange 4 of the speaker grill 1 by its elasticity, and the straight portion 16b abuts on the edge of the speaker opening 11 of the door trim 10, so that the speaker grill 1 and the door trim 10 are fixed via a spring wire 16, and a stopper 18 prevents the spring wire 16 from coming off.

As described above, the frame member 2 of the speaker grill 1 is provided with the flange 4 penetrating into the opening 11 of the door trim 10, the fitting hole 15 is provided in the flange 4, and the spring wire 16 is provided on the rear side of the door trim 10. By providing a stopper 18 for preventing the slip-off, it is possible to fit the engaging portion 16a of the spring wire 16 into the fitting hole 15 of the flange 4 and at the same time push the linear portion 16b between the stopper 18 and the stopper. Since the speaker grill 1 is mounted, the number of parts for mounting is reduced and no special tool for mounting is required, so that the speaker grill 1 can be mounted easily. Further, for the same reason, there is an effect that the installation work time is shortened.

[0026]

[Effect of device]

 As described above, according to the present invention, the main body of the interior component is provided with the locking projection that penetrates into the trim hole, and the locking projection is provided on the locking projection on the back side of the trim hole. An elastic member that locks and comes into contact with the rear surface of the trim is provided, and a stopper that prevents the elastic member from coming off is provided near the trim hole. By engaging the elastic member with the locking projection provided on the main body, the elastic member comes into contact with the back surface of the trim, so that the trim and interior parts are fixed through the elastic member, and the elastic member is removed by the stopper. Is prevented. Therefore, it is easy to attach the interior parts to the door trim in a short time, and since screws are not used, the size of the interior parts protruding from the trim surface is small and a sense of unity appears, resulting in a good-looking fixed structure of interior parts. You can
