DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a housing accessory such as a room lamp and a console, which is mounted on an adherend such as an automobile interior material, and a mounting method thereof.

[0002]

2. Description of the Related Art In general, passenger compartments of automobiles are decorated and protected by coating various interior materials on steel plates constituting the passenger compartment. For example, the ceiling of the passenger compartment is covered with a headliner interior material. The headliner interior material is formed by molding a thermoplastic resin or the like into a shape along the ceiling of an automobile, and then attached to a steel plate on the ceiling with a fixture such as a clip. In addition, various accessories used by occupants in the interior of the vehicle are mounted on the ceiling of the vehicle or the like. Such accessories include accessories with a relatively small mounting area, such as sun visors and assist grips, and accessories that form a storage space (housing), such as a room lamp housing or console housing. There are large accessories to store the main unit. Conventionally, these accessories have been attached to the automobile steel plate on the ceiling or the headliner interior material with various types of clips and screws sandwiching the headliner interior material therebetween.

On the other hand, in recent years, there has been proposed a mounting structure in which these accessories can be easily snap-in mounted on a steel plate or an interior material without using clips or screws, simply by touching.

For example, Japanese Patent Application Laid-Open No. 11-348657 (Japanese Patent Application No. 10-157886) discloses a configuration in which a room lamp, which is a large accessory, is attached to a room lamp support bracket provided on a vehicle body. . According to this, the plurality of hooks (engaging portions) provided on the room lamp are engaged with the room lamp support bracket through openings formed in the ceiling lining (head liner), so that the room lamp is provided. Fixed. In this case, after the hook provided in the room lamp is bent inward and the head liner is opened, the force to bend the hook is released, and the hook is returned to its original position by elasticity. The outward claws are engaged with the bracket on the back of the headliner.

[0005]

The above prior art has the following problems.

The support of the accessory by the bracket is based on the hook of the hook engaging the engaged portion of the bracket. The amount of engagement between the claw and the engaged portion is determined by the amount of bending of the hook. Due to its structure, the amount of deflection of a hook made of synthetic resin or the like is limited to a maximum of several millimeters. Since the engaging portion cannot withstand the load and cannot support it, it is difficult to attach it to the blanket.

[0007] In order to remove the accessory once attached, it is necessary to apply an external force to the accessory to elastically deform the hook, resulting in poor maintainability of attachment and detachment. It is not easy to apply an external force to deform the hook. Forcibly applying the force may damage the hook of the accessory and make it impossible to reuse the accessory, or may damage the opening edge of the headliner interior material.

It is necessary to prepare a bracket or the like for receiving accessories on the back surface of the head liner in advance. In addition, a large gap is required on the back surface of the headliner for the bracket and the like, and a dead space is generated between the headliner and the steel plate, and as a result, the capacity of the passenger compartment is reduced.

In view of the above problems, an object of the present invention is to provide
It is an object of the present invention to provide a housing accessory mounting structure and a mounting method which can be easily snap-in mounted to an adherend and have excellent mounting strength and maintainability.

A groove-shaped recess is provided at the edge of the peripheral wall. This concave portion is a portion to be engaged with the engaging portion of the cover portion.

The cover part 4 is composed of a bottom plate and an upward peripheral wall, and is formed in an upward concave shape. At the edge of the peripheral wall of the cover 4, a plurality of engaging portions 6 each of which includes a column 6 a that can be flexibly deformed and a claw 6 b provided at the tip of the column 6 a. The claw portion 6b of the engaging portion 6 can engage with a concave portion (not shown) of the base portion 3. That is, the cover portion 4 is attached to the base portion 3 by engaging the claw portions 6b of the plurality of engaging portions 6 with the groove-shaped concave portions of the base member 3. In this mounting state, the two concave shapes are joined to form a space 5 that is surrounded by the peripheral wall and houses the accessory body (lamp unit 2).

A plurality of engaging ribs 7 are provided on the top plate of the base portion 3 so as to extend upward. The engagement rib 7 is
a and an engaging flange 7b protruding outward at the upper end of the column 7a. The engaging rib 7 extends toward an attachment elliptical hole 9 for an adherend, which will be described later, and the height of the support portion 7a corresponds to the thickness of the adherend. The support portion 7a and the engagement flange portion 7b of the engagement rib 7 may be formed integrally, or may be divided into a plurality. In the present embodiment, a pair of engagement ribs 7 are provided facing each other with the engagement flange 7b facing outward. Each engagement flange 7b of both engagement ribs 7
Is shorter than the major axis of the elliptical hole 9 and longer than the minor axis.

The top plate of the base 3 of the present embodiment is provided with a pair of elongated through holes 10 adjacent to the engagement ribs 7. An insertion rib 11 facing the through hole 10 of the base portion 3 is provided upright on the bottom plate of the cover portion 4. The insertion rib 11 extends toward the through hole 10 of the base portion 3 and has a height capable of protruding above the top plate of the base portion 3 through the through hole 10.

Next, the adherend to which such a housing accessory 1 (base 3 and cover 4) is attached will be described. In the present embodiment, the headliner interior material 8 at the ceiling of the passenger compartment of the automobile is the adherend,
The headliner interior material 8 is provided with an oval hole 9 for mounting a housing accessory. Note that the shape is not necessarily an exact elliptical shape in a strict sense as long as the shape is similar to the elliptical shape.

As described above, since the distance between the outer edges of the engagement flanges 7b of both engagement ribs 7 is shorter than the major axis of the elliptical hole 9 and longer than the minor axis, FIGS. As shown in the figure, when the two engaging ribs 7 are located near the minor axis of the elliptical hole 9 of the adherend, the engaging flanges 7b of the two engaging ribs 7 engage with the inner edges of the elliptical hole 9 respectively. Then, the base portion 3 is attached to the headliner interior material 8. On the other hand, when the two engaging ribs 7 are located near the major axis of the elliptical hole 9 of the adherend, the engaging flange 7b of the both engaging ribs 7 The base portion 3 remains detached from the headliner interior material 8 without engaging with the inner edge portion. Accordingly, by rotating both engagement ribs 7 in a state of being inserted into the elliptical hole 9, the state where the base portion 3 is attached to the headliner interior material 8 and the state where the base portion 3 is detached are alternately taken.

The distance between the outer edges of the pair of insertion ribs 11 is shorter than the major axis of the elliptical hole 9 and longer than the minor axis. The insertion rib 11 can be inserted into the through hole 10 of the base 3.
The insertion ribs 11 can be inserted in the vicinity of the major diameter of the elliptical hole 9, but the gap between the insertion ribs 11 is wide and each insertion rib 11 itself has a certain width. Therefore, insertion is not possible near the short diameter portion of the elliptical hole 9 or at an intermediate position between the long diameter portion and the short diameter portion. That is, both insertion ribs 1
1 is inserted in the vicinity of the major axis of the oval hole 9 and then the cover 4 is inserted.
To rotate relative to the base 3,
Since the insertion rib 11 is in contact with the inner edge of the elliptical hole 9, it cannot be rotated.

In the housing accessory mounting state according to the present embodiment as shown in FIGS. 6 to 8, the engagement flange 7 b of the engagement rib 7 is engaged with the vicinity of the short diameter of the elliptical hole 9 so that the base 3 Is attached to the headliner interior material 8, and the cover portion 4 is attached to the base portion 3 by engaging the claw portions 6 b of the engaging portion 6 with the groove-shaped concave portions. Then, the insertion rib 11 penetrates the through-hole 10 and the cover 4
Are integrated with the base portion 3. Since the insertion rib 11 is inserted in the vicinity of the major diameter of the elliptical hole 9, the cover 4 and the base 3 cannot rotate relative to the headliner interior material 8. Therefore, since the engaging rib 7 cannot rotate relative to the elliptical hole 9 of the headliner interior material 8, the engaging flange 7b does not come off from the inner edge of the elliptical hole 9 and the cover 4 and the base The part 3 does not come off from the headliner interior material 8.

Next, the housing accessory mounting method of the present embodiment will be described.

First, as shown in FIG. 3, the base portion 3 is brought into close contact with the headliner interior material 8 in a positional relationship such that the engagement flange portion 7b is located near the major axis of the oval hole 9 of the headliner interior material 8. Let it. At this time, the engagement rib 7 enters the elliptical hole 9.

Subsequently, as shown in FIG. 4, the base 3 is rotated by 90 degrees in parallel with the surface to be attached, and the engagement flange 7b is inserted into the elliptical hole 9 as shown in FIG.
Is engaged with the inner edge near the minor axis. At least a part of the engaging flange 7b goes around the back surface of the headliner interior material 8, and the upper surface of the top plate of the base 3 and the (lower surface of) the engaging flange 7b.
The base part 3 is temporarily fixed to the headliner interior material 8 by sandwiching the headliner interior material 8. Note that the engaging flange 7b is just in contact with the back surface of the headliner interior material 8, that is, the height of the support portion 7a below the engaging flange 7b is substantially equal to the thickness of the headliner interior material 8. The height of the column 7a is defined.

After the base portion is temporarily fixed as described above, the cover portion 4 is disposed so as to be laminated on the base portion 3 as shown in FIGS. At this time, while inserting the insertion rib 11 extending upward from the bottom plate of the cover part 4 into the through hole 10 of the base part 3, the column part 6a of the engaging part 6 of the cover part 4 is elastically deformed, and the claw part 6b Is engaged with the groove-shaped concave portion of the base portion 3. In addition, the engagement between the cover 4 and the base 3 is not limited to this example, and various fitting connections can be made. As shown in FIG. 8, the tip of the insertion rib 11 penetrating the through hole 10 of the base portion 3 projects into the oval hole 9 of the headliner interior material 8. The base portion 3 temporarily fixed by the tip of the projecting insertion rib 11 cannot be rotated, and cannot be removed unless the cover portion 4 is removed.

When the user removes the housing accessory 1, a procedure substantially reverse to the above-described mounting method is performed. First, the pillar 6a is bent and deformed to remove the claw 6b of the engaging portion 6 from the groove-shaped concave portion, and the cover 4 is removed from the base 3. Then, the insertion rib 11 is pulled out from the elliptical hole 9 and the through hole 10, so that the base portion 3 can be rotated relative to the headliner interior material 8. Then, the base part 3 is rotated about 90 degrees, the engagement rib 7 is positioned near the major axis of the elliptical hole 9, and the base part 3 is removed from the headliner interior material 8. Since the engagement flange 7b is located near the major axis of the elliptical hole 9, it does not catch on the inner edge.

As shown in FIG. 9, when the contact portion of the engagement flange 7b with the headliner interior material 8 is tapered, the force by which the engagement flange 7b tightens the headliner interior material 8 is increased. Stronger, more secure fixation.

Further, as shown in FIG. 10, it is preferable that the pair of engagement flanges 7b be inclined with respect to the headliner interior material 8 in different directions. In this case, the inclined engagement flange portion 7b acts to tighten the headliner interior material 8 (when the back surface of the headliner interior material 8 has elasticity, the engagement flange portion 7b bites into the headliner interior material 8). With this structure, displacement and rattling of the base 3 are prevented.

[0033]

According to the present invention, a housing accessory can be mounted by one-touch snap-in mounting without using mounting members such as mounting clips and screws. In addition, if the cover is removed from the base, the accessory can be removed without applying excessive force, which is excellent in maintenance.

Since a strong engaging force with the adherend can be secured,
Large and heavy housing accessories can also be attached. In addition, it is possible to prevent the accessory from rattling or loosening the engagement state. In addition, it is attached to the back surface of the adherend even if there is no large gap, and there is no waste of space. It is not necessary to provide a special member such as a mounting bracket on the back surface of the adherend, and it is not necessary for the mounting operator to perform a complicated operation of putting a hand on the back surface.
