Description

[Detailed description of the invention] (Field of industrial application) The invention mainly relates to the floor lining of automobiles.
This is used in the technical field of clips for attaching elastic materials to attachment members.

(Prior Art) Conventionally, as shown in Fig. 5, an elastic material d consisting of an elastic member b and a mat c is attached to a mounting member a with a clip e, as shown in Fig. 5. A gasket is made by passing through a drilled hole f and locking it, or by double-injection molding a hard resin flange part g and a soft resin h having rubber-like elasticity at the lower part of the flange part, as shown in Fig. 6. i
The locking method is disclosed in Japanese Utility Model Application Publication No. 57-176913. However, in the locking structure shown in Fig. 5, the clip e strongly compresses the elastic material d to the mounting member a, so the elastic function of the elastic material d is lost, the vibration damping and sound insulation effects in this part are weakened, and the mounting Part a
Water, etc. enters through the hole f drilled in the mounting member a.
This will cause corrosion. Further, although the structure shown in FIG. 6 has a waterproof effect due to the packing i, it does not provide vibration damping or sound insulation, and is not suitable for clipping thick elastic materials such as the one proposed in the present invention. Further, in the structure disclosed in Japanese Patent Publication No. 48-9867, there are problems in that the elastic material is strongly compressed and loses its elastic function, and the water sealing property is not sufficient.

(Purpose of the invention) In view of these conventional problems, the present invention provides a cylindrical elastic body around the outer periphery of the clip, and the cushion of this elastic body locks the elastic material to the mounting member, thereby suppressing vibrations, insulating sound, and The purpose is to provide a clip with significantly superior waterproof performance.

(Structure of the invention) The structure of the invention is for attaching an elastic material, such as a cushion material and a mat, to a mounting member, such as a floor panel of an automobile, and a flat plate on the top that abuts the elastic material and fastens the elastic material. A head shaped like a shape is provided, and a horsetail-shaped protrusion is provided on the lower surface of the head, and an engaging part is formed that bulges outward from the body of the protruding part, and the engaging part A cylindrical elastic body is integrally formed around the body, such that when the body is inserted into the mounting hole of the mounting member, the end portion is pressed against the mounting member and an elastic force is exerted between the mounting member and the head. This is a clip for attaching an elastic material.

(Example) An example of the present invention will be described below based on the drawings. As shown in Figures 1 to 4, clip 1
is molded from synthetic resin, and is provided with a flat plate-shaped head 2 that comes into contact with an elastic material 11 (described later) to stop the elastic material, and a horsetail-shaped protrusion 3 is provided on the lower surface of the head, The protruding portion consists of a body portion 4 and a bulging portion 5, and an engaging portion 6 is formed between the body portion 4 and the bulging portion 5. A cylindrical elastic body 7 is provided on the outer periphery of the body 4, and a bellows-shaped elastic part 8 is formed in the middle part of the cylindrical elastic body 7. An elastic force acts between the mounting member 9 and the head 2. Next, the lower surface of an elastic member 12 made of foamed urethane or the like is adhered to the upper surface 16 of the mounting member 9, a skin material 13 made of butyl rubber or the like is adhered to the upper part of the elastic member 12, and then the upper surface of the elastic member 13 is adhered. A mat 14 having bristles at the base is placed thereon, and the elastic member 11 is formed by the elastic member 12, the butyl rubber skin material 13, and the mat 14. The elastic material 11 is provided with an insertion hole 15 through which the cylindrical elastic body 7 of the clip 1 is inserted. Next, to explain how to attach the clip 1, the clip 1 is now inserted into the insertion hole 15 of the elastic material 11,
Furthermore, the tip of the bulging portion 5 of the clip 1 is fitted into the mounting hole 10 drilled in the mounting member 9, and the mounting member 9
When strongly pressed in the direction, the bulging portion 5 penetrates the mounting hole 10 and projects downward from the mounting member 9, and the engaging portion 6 expands and engages with the mounting hole 10. At the same time, the cylindrical elastic body 7 is compressed, and its bottom part is attached to the upper surface 16 of the mounting member 9.
The clip 1 is pressed against the mounting member 9.
The elastic material 11 is fixed to the mat 1 of the elastic material 11.
4 is also fixed.

In the embodiment, the cylindrical elastic body 7 includes the head 2,
Although an example has been described in which the cylindrical elastic body is integrally molded from the same material as the horsetail-shaped protrusion 3, it is also possible to create a structure in which this cylindrical elastic body is molded separately from the head 2 and the horsetail-shaped protrusion 3 and then integrally joined. . Furthermore, although the body portion 4 and the engaging portion 6 are cylindrical in the above embodiment, they may have a structure in which the arcuate cross-sectional portions face each other.

(Effect of the invention) Since the clip of the present invention has the above-mentioned configuration, the clip penetrates the elastic material, the engaging portion expands at the lower surface of the mounting hole and engages with the mounting hole, and at the same time, the clip penetrates the elastic material. is compressed, and the clip is fixed by the repulsive force of the cylindrical elastic body and the locking of the engaging part, and the elastic material is not compressed to the extreme as in the past, so the vibration damping and sound insulation effects of the elastic material are Furthermore, since the bottom of the cylindrical elastic body is crimped onto the top surface of the mounting member, it has the excellent effect of preventing corrosion of the mounting member due to ingress of water or the like.
