【Example】

Next, embodiments of the present invention will be described based on the attached drawings. FIG. 2 shows the entire door trim 2 to which the speaker grill 1 is attached, and FIG. 2 is a sectional view taken along the line A-A in FIG. 2, showing the main parts of the mounting structure of this example.

[0020] First, the door trim 2 is made of wood-based material or synthetic wood, for example, as shown in Fig. 1. A trim base material 3 in which fat is formed into a substantially flat plate shape and wrapped on the surface of this trim base material 3. The outer skin material 6 is made of

[0021] At the door speaker mounting position on the trim base material 3, there is a An opening 2a of an appropriate size is formed. The above speaker grill 1 is The opening 2a is installed in a shielded manner. This mounting structure will be explained later. Ru.

[0022] The skin material 6 includes a pad 4 wrapped on the trim base material 3 and a pad 4 wrapped on the trim base material 3. and a skin 5 forming the surface of the door trim 2, formed on the trim base material 3. Similarly, an opening 6a for a speaker is formed approximately concentrically with the opening 3a. There is. This opening 6a is formed by, for example, ultrasonic waves or high frequency waves, as will be described later. The opening of the trim base material 3 is formed by a weld cut. It is formed to have a slightly smaller diameter than 3a.

[0023] The door trim 2 is constructed as described above. The mounting structure of the speaker grill 1 will be explained. This speaker grill 1 has a thin steel plate that extends from the opening 2a of the door trim 2, for example. It is formed in the shape of a disk with a diameter larger than that of the opening 3a. a mounting edge 8 formed with a predetermined width on the outer circumferential side of the grill main body 7; It consists of

[0024] The grill main body 7 is formed with a step slightly to the left (indoor side) of the mounting edge 8 in the figure. It is formed so as to be substantially flush with the skin material 6 of the door trim 2. Ma In addition, a large number of small diameter holes 7a to 7a are formed over the entire surface of the grill body 7. It is formed into a so-called punched metal shape.

[0025] Near the inner circumference of the mounting edge 8 (close to the grill body 7), there are mounting holes 8a to 8a with a predetermined diameter. 8a are formed at appropriate number of locations along the outer periphery of the grill main body portion 7. This mounting hole A ring-shaped ornament 9, which will be described later, is attached to 8a to 8a. Also, mounting On the back side of the edge 8, near the outer periphery, there is a locking pawl (so-called a bar) cut and raised in an inclined manner. ring claws) 8b to 8b are formed at appropriate locations.

[0026] The speaker grill 1 formed in this way is located at the middle of the mounting edge 8 as shown in the figure. The outer circumferential side is sandwiched and fixed between the trim base material 3 and the skin material 6, so that the trim It is attached with the opening 3a of the rim base material 3 being shielded. In other words, as described below The trim base material 3 is formed by biting the locking claws 8b to 8b of the mounting edge 8. By being shaped, the mounting edge 8, that is, the speaker grill 1 is fixed to this trim base material 3. It has been established.

[0027] The ornament 9 described above is formed into a ring shape by integral molding of synthetic resin. It is attached along the outer periphery of the grill main body part 7. this ornament Attachment holes 8a to 8a formed in the speaker grille 1 are provided on the rear surface 9a side of the speaker grille 9. Correspondingly, cylindrical mounting posts 9b-9b are formed, and these mounting posts 9b-9b are As will be described later, they are inserted into the respective mounting holes 8a to 8a, and their tips are melted. By being deformed into a flat shape, it is prevented from coming off from the mounting edges 8a to 8a, and the A component 9 is attached to the speaker grill 1.

[0028] In addition, this ornament 9 can also be attached to the grill body 7 or the door trim skin material 6. It is formed so that it is almost flush with the other hand. Also, this ornament 9 is a door It is attached by sandwiching the skin material 6 of the trim 2, and the end of the opening of the skin material Also serves as processing.

[0029] Next, a procedure for attaching the attaching structure according to the above configuration will be explained based on FIG. 3. First, the trim base material 3 is molded. The periphery of the opening 3a of the trim base material 3 overlaps the back side of the mounting edge 8 of the cover grille 1. It is done like a monkey.

[0030] By forming the trim base material 3 in this way, the locking claws 8 of the speaker grille 1 b to 8b are engaged with the trim base material 3 in a biting manner, and therefore, the trim base material 3 A speaker grill 1 is attached to this trim base material 3 at the same time as the trim base material 3 is formed. It is.

[0031] After fixing the speaker grill 1 to the trim base material 3 as described above, Attach the skin material 6 to the indoor side surface of 3 (the side where the speaker grill 1 is attached). Let's go. Here, in order to cut out and form the opening 6a in the trim base material 3 later, Grill main body part 7 of peaker grill 1 and mounting holes 8a to 8a for attaching ornaments The portion corresponding to (range indicated by B in the figure) is masked in advance.

[0032] After pasting the skin material 6 on the trim base material 3, the surface of the masked part The skin material is cut out to form an opening 6a. This cutting process can be done, for example, by This is done by ultrasonic or high frequency welding 10.

[0033] Once the opening 6a is cut out and formed in this way, pinch the ends of the opening 6a. Ornament 9 is attached with great care. At this time, the mounting pillar 9b of the ornament 9 ~ 9b are respectively inserted into the mounting holes 8a to 8a formed in the mounting edge 8 of the speaker grill 1. is inserted.

[0034] After that, the tips of each of the mounting columns 9b to 9b are cut with a predetermined tool (horn) 11. is melted and deformed to prevent it from coming off from the mounting hole 8a, so that the owner A member 9 is attached to surround the grill body 7. As described above, the speaker grill 1 is installed almost flush with the door trim 2. It is possible.

[0035] In this example, since the mounting structure is based on the configuration explained above, the effects described below will be explained. It is effective. In the speaker grill 1 of this example, the grill main body 7 and the mounting edge 8 are integrally constructed, The mounting edge 8 is sandwiched between the door trim base material 3 and the skin material 6 by the locking claws 8b to 8b. The door trim 2 is attached by being inserted and fixed.

[0036] For this reason, it is difficult to draw the opening of the door trim and use the speaker grill as in the past. Since there is no need to provide a mounting seat for mounting the door trim, the manufacturing process of the door trim is simplified. be done.

[0037] Also, there is no need to attach the grill body 7 to the mounting edge 8, which corresponds to a conventional frame. Moreover, since it is not configured to be fixed with screws, it is difficult to install this speaker grill 1. It becomes easier to automate tasks.

[0038] Although the explanation of the speaker body is omitted, there is a A mounting section is formed, and the structure is integrally attached to the speaker grill via this mounting section. Alternatively, it may be installed on the door panel side, as shown in the example below. The mounting structure of the speaker grille does not pose any problem when mounting the speaker body. It's not something you can do.

[0039] In addition, the ornament 9 is designed to enhance the design effect by processing the ends of the skin material 6. It is installed for the purpose, for example, to reduce the cost for lower class car models. It may be omitted to reduce the number of items. Therefore, the mounting hole 8a of the speaker grill 1 ~8a is unnecessary. In this case, the skin material 6 is used for mounting the speaker grill 1. In addition to wrapping the entire edge 8, the welded cut edges are treated to look nice. You need to do it well.

[0040]
