DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting a relatively small mounting member such as a mounting ring for mounting a speaker grill to a relatively large mounting member such as an automobile door trim. About.

[0002]

2. Description of the Related Art FIG. 6 shows a known mounting structure of this type. According to FIG. 6, for example, when attaching a relatively small attachment member 1 such as a grill attachment ring for attaching a speaker grill 8 to a relatively large attachment member 2 such as a door trim, for example, A concave mounting portion 3 having a bottom is formed in a part of 2, and a plurality of through holes 5 are formed in a bottom portion 4 of the concave mounting portion 3 so as to be apart from each other.

On the mounting member 1 side, engaging pieces 6 corresponding to the through holes 5 are formed from the back side.

[0004] Then, as shown in FIG.
The inner wall 3a is slid while being elastically deformed in the radially reduced direction by the inner wall 3a of the concave mounting portion 3, and the inner wall 3a is inserted into the through hole 5 so that the engaging projection 7 formed on the outer end of the engaging piece 6 at the outer side of the concave portion has the concave mounting portion. The mounting member 1 is mounted on the mounted member 2 by engaging with the outer peripheral wall of the bottom wall 4 of the mounting member 3.

[0005]

However, when the mounting member 1 is mounted on the member 2 to be mounted, when the engaging projection 7 slides on the inner wall 3a of the concave mounting portion 3, the inner wall 3a surface is rubbed. As a result, a scratch X may be made on the inner wall 3a surface, and since the scratch X can be observed from the outside (in the direction of the arrow), the appearance has deteriorated.

SUMMARY OF THE INVENTION In view of the above, the present invention provides a mounting device designed so that the mounting member can be mounted on the mounting member without damaging the mounting member side when mounting the mounting member on the mounting member. An object of the present invention is to provide a mounting structure of a member.

[0007]

In order to achieve the above object, the present invention provides a mounting structure for mounting a relatively small mounting member to a relatively large mounting member.
Forming a bottomed concave mounting portion on a part of the mounted member,
A through hole is provided at the bottom of the concave mounting portion, and an engaged piece extending from a side wall of the concave mounting portion is formed so as to protrude into the through hole. An engaging piece is erected, an engaging hole is formed near the tip of the engaging piece, and after the engaging piece is inserted into the through hole, the engaged piece is engaged with the engaging hole. Then, the mounting member is mounted on the mounted member.

According to the present invention, the mounting member is fixed to the mounted member by engaging the engaged piece on the concave mounting portion side with the engaging hole on the mounting member side. Even if the engaging piece is rubbed on the engaged piece in order to elastically deform the engaging piece on the side, the damaged portion is hidden by the attached member, and the engaging piece is concave. Since the inner wall of the mounting portion is not rubbed during the mounting process, the appearance can be improved.

Alternatively, according to the present invention, at least a plurality of positioning posts are formed from the back side of the mounting member, and positioning holes into which the positioning posts are fitted are formed at the bottom of the concave mounting portion. The engagement of the engagement piece with the engagement portion is performed while positioning the attachment member with respect to the attachment member by fitting the positioning post to the engagement member.

[0010] As a result of this configuration, the mounting member is positioned with respect to the member to be mounted by the positioning support, and from this point, it is possible to prevent the engaging piece from rubbing the inner wall of the concave mounting portion.

Alternatively, the present invention is characterized in that the member to be mounted is a door trim for a vehicle, and the mounting member is a mounting ring of a speaker grill mounted on the door trim for a vehicle.

[0012] The mounting structure of the present invention configured as described above,
By using the mounting structure of the speaker grill mounting ring with respect to the door trim, the mounting ring can be mounted without damaging the door trim, thereby contributing to the improvement of the appearance of the door trim.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an automobile door trim which is a member to be mounted, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG.
3 is an exploded perspective view showing a part of the door trim in FIG.

In FIG. 1, a grill mounting ring, which is a relatively small mounting member, is attached to a door trim 12 of an automobile, which is a relatively large mounting member, so that a part of the door trim 12 has a substantially bottomed bottom. Circular concave mounting part 1
3 and a through hole 15 is formed in the bottom portion 14 of the concave mounting portion 13.
Are provided.

An engaged piece 20 is formed to extend on the side wall 13b of the concave attachment portion 13 so as to project into the through hole 15.

The grill mounting ring 11 has a substantially circular shape so as to fit into the concave mounting portion 13, and is configured to mount the speaker grill 18. An engagement piece 16 is provided upright from the back side of the grill attachment ring 11, and an engagement hole 21 is formed near the tip of the engagement piece 16.

To attach the grill attachment ring 11 to the door trim 12, insert the engagement piece 16 into the through hole 15,
This is performed by engaging the engaged piece 20 with the engagement hole 21.

In the mounting process, the engaging piece 16 is elastically deformed toward the center by the engaged piece 20 when the tip end portion of the engaging piece 16 passes through the through-hole 15. The outside of the distal end portion of the engaging piece 16 is rubbed to some extent. Even if the engaging piece 16 is damaged by this rubbing, the door trim 12 hides this portion.

Further, the inner wall 13a of the concave mounting portion 13 is not rubbed by the engagement piece 16 and is not damaged.
This contributes to improving the appearance of the door trim 12.

FIGS. 4 and 5 show another embodiment of the present invention. FIG. 4 is an exploded perspective view showing a part of an automobile door trim shown in FIG. 1 in an enlarged manner, and FIG. It is -A sectional drawing.

In FIGS. 4 and 5, in this embodiment, a plurality of positioning posts 22 are provided on the bottom wall 11a of the grill attachment ring 11 in comparison with the first embodiment. A positioning hole 23 into which the positioning column 22 fits is formed in the bottom 14 of the concave mounting portion 13.
The positioning support column 22 is formed to be longer than the engagement piece 16, and when the grill attachment ring 11 is attached to the door trim 12, the engagement piece 16 and the engaged piece 20 are associated with each other. Previously, the positioning posts 22 are fitted into the positioning holes 23 so that the grill mounting ring 11 can be positioned with respect to the door trim 12. Further, by providing slits on both sides of the engaged piece 20, the amount of deflection of the engaged piece 20 may be increased. The slit is set at a height hidden by the grill attachment ring 11 so as not to impair the aesthetic appearance.

[0023]

As described above, according to the present invention, the mounting member is fixed to the mounted member by engaging the engaged piece on the concave mounting portion side with the engaging hole on the mounting member side. Therefore, even if the engaging piece is rubbed on the engaged piece to elastically deform the engaging piece on the mounting member side and is injured, the damaged portion will be hidden by the mounted member, and In the process in which the engagement piece attaches the inner wall of the concave attachment portion,
Since there is no rubbing, an improvement in beauty can be expected.
