[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clip for fixing an interior material of a vehicle, which can prevent water from entering the room from a body panel, and can be easily assembled and can exhibit excellent workability. .

[0002]

[Prior art]

 For example, an automobile interior trim fixing clip used for mounting an automobile door trim is basically composed of a head portion, a neck portion, a flange portion and a leg portion, and is capable of exerting a sealing action on the flange portion. There is widely used a structure in which the legs vertically provided at the center of the lower surface of the device have an engaging action with the body panel (for example, see Japanese Patent Laid-Open No. 3-113108).

However, in the conventional clip for fixing the interior material of this type of automobile, the clip is formed in a cage shape in order to increase the elasticity of the legs and easily secure the diameter reduction. Since it depends only on the flange portion, a perfect seal cannot be achieved, and therefore, when the clip is engaged with the body panel, there is a problem that water that enters through the basket leaks to the head side. In addition, in order to prevent such a problem of water leakage, it has been attempted to attach a water absorbing pad between the leg portion and the flange portion, but in this case, the assembling work becomes complicated and the work is complicated. There was a problem that the efficiency was significantly reduced and the cost was significantly increased.

[0004]

[Problems to be solved by the device]

 The present invention solves the above-mentioned conventional problems, can reliably prevent water leakage between the body panel and the room, and is easy to assemble and exhibits excellent productivity. The present invention has been completed with the object of providing a clip for fixing the interior material of an automobile which can be manufactured at a low cost without using a sealing material such as a special water absorbing pad.

[0005]

[Means for Solving the Problems]

 The clip for fixing the automobile interior material of the present invention made to solve the above problems is an automobile interior material in which a diameter-reducible leg portion for engaging a body panel is vertically provided at the center of the lower surface of a sealing flange portion. In the fixing clip, the leg portion is characterized in that the leg portion is composed of a tubular sleeve portion having an intermediate portion as a maximum diameter portion and a tapered guide portion continuing from the tip thereof.

【Example】

 The present invention will now be described in detail with reference to the illustrated embodiment. The drawing shows a clip according to the present invention used for a door trim board of an automobile, in which 1 is a cylindrical neck, 2 is a donut plate-shaped head formed on the top, and 3 is a neck 1. A flange portion 4 for sealing, which follows the upper bottom plate formed below, is a leg portion 4 which is provided at the center of the lower surface of the flange portion 3 and which can be reduced in diameter for engaging a body panel. For example, it is the same as the conventional clip of this kind in that it is integrally molded of elastic synthetic resin such as polyethylene.

The leg portion 4 has a barrel-shaped tubular sleeve portion 5 extending from the flange portion 3 to a lower portion through a so-called dead point D which is the maximum diameter portion of the leg portion 4 and an intermediate portion thereof, and the tubular portion. The guide portion 6 is formed to extend from the sleeve portion 5 to the tip while gradually reducing its diameter. In the embodiment, the guide portion 6 is divided into three portions extending equally from the tubular sleeve portion 5 as the guide portion 6. Of fins 6a. Further, the tubular sleeve 5 is provided with a vertically long ridge 7 on the outer surface so as to be positioned in the middle between the tension positions of the fins 6a of the guide portion 6, and corresponds to the ridge 7. As shown in the figure, a vertically elongated meat-thickening portion 8 is provided on the inner surface of the tubular sleeve 5 so that the diameter can be easily reduced. As shown in FIG. 3, the fin 6a has an arc shape slightly curved in the same direction so that the fin 6a can be easily deformed inward, and when the external force is applied to the tubular sleeve 5, the diameter of the fin 6a is reduced. Is not disturbed.

[0008]

[Action]

 With this structure, the seal board 3 is inserted into the large-diameter portion 12 of the gourd-shaped retainer fitting hole 11 provided in the trim board 10 until the sealing flange portion 3 contacts the trim board 10. As indicated by the two-dot chain line arrow in FIG. 2, the trim board 10 is forcibly moved from the large-diameter portion 12 side to the small-diameter portion 13 side through the reduced-diameter passage 14 and the trim board 10 is attached to the head portion 2 and the flange. The body panel 20 is mounted in a predetermined position by engaging and engaging with the portion 3 and engaging the engaging hole 21 of the body panel 20 with the leg portion 4 vertically extending from the flange portion 3. The point is similar to the conventional clip of this type, but in the present invention, as shown in FIG. 1, the upper half of the leg portion 4 extends from the flange portion 3 to a portion below the dead point D. The body 5 is formed with a body When engaged with the panel, the tubular sleeve 5 projects from the body panel 20 and forms a vertical peripheral wall around the engagement hole 21, so that the body panel 20 is directed toward the indoor side. Intrusion of water is prevented by the tubular sleeve 5, and a double sealing structure is formed by the sealing action of the elastic force of the flange portion 3 located inside the body panel 20, resulting in water leakage. The phenomenon will be completely eliminated.

When the body panel 20 and the leg portion 4 are engaged with each other, the engagement hole 21 of the body panel 20 is guided by the tapered guide portion 6 at the tip of the leg portion 4 and is smoothly inserted. Be touched. In addition, as in the embodiment, the protrusion 7 and the meat stealing portion 8 are provided on the tubular sleeve 5, so that the tubular sleeve 5 of the leg portion 4 has a vertically long shape as shown in FIG. The protrusion 7 and the meat-thickness portion 8 on the inner surface easily deform inward when passing through the engagement hole 21, so that the dead point D can be easily completed with a particularly small insertion load, and then the shape can be restored again. The body panel 20 and the leg portion 4 are firmly engaged with each other.

In the embodiment, the guide portion 6 below the tubular sleeve 5 is composed of a plurality of curved fins 6a so as not to prevent the diameter reduction of the tubular sleeve 5. However, the shape of the tubular sleeve 5 having a plurality of vertically elongated holes as a bullet-like tapered portion is arbitrary according to the body panel 20 to be engaged. It goes without saying that the design can be changed to one.

[0011]

[Effect of device]

 As is clear from the above description, the present invention can reliably prevent water leakage between the body panel and the room, is easy to assemble, and exhibits excellent productivity. The cost can be reduced without using a sealing material such as a water absorbing pad. Therefore, the present invention has an extremely great practical value as a clip for fixing an interior material of an automobile, which eliminates the conventional problems.
