Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to an improved method for mounting the base of a clip on a plate.

(Prior art and corner points) For example, as shown in FIG. A carpet to be laid on a floor etc. - A fitting part 2 is formed by wrapping the edge of the shade and fitting it into the floor to fix it, and the other side edge is made of soft resin etc. The tongue piece 3 is integrally formed, and a dovetail-shaped guide rail 4 is formed on the back side of the tongue along the longitudinal direction. The plate 1 is made by cutting a plastic molded product to an appropriate length, and the end piece A and tab 5 are integrally molded on both ends of the main body by injection molding etc. (In the figure, the end piece A and tab 5 are formed at one end ).

When fixing the Kiraking plate configured in this way on the floor of a car, one end of the clip is fixed inside the guide rail 4, and the end of the clip is fitted to the floor, so that the Kiraking plate can be fixed on the floor of the car. : Attach the ring plate to the floor J: I'm doing it.

There are two types of materials for clips that have this special function: one made of bent iron and one made of synthetic resin, but iron clips have a stronger fit and last longer.
It is easy to use and inexpensive. However, when iron clips are used in the above-mentioned Kirakink play-1~, the play 1 is a place where there is a possibility of being constantly soaked in mud or water,
Resin clips are used instead of iron clips in such locations because they are susceptible to rust and corrosion. On the other hand, as a specific material for this resin clip, delrin, dicoracon, etc. are generally used because they require a certain degree of strength, but such f, r + A 11 is difficult to plasticize with heat,
Furthermore, since the compatibility with the resin material constituting the plate is poor, the base portion could not be fixed to the plate by ultrasonic application or the like.

Therefore, as a conventional resin clip, a clip 6 having the shape shown in FIG. 1 was used and fixed to the plate by the following attachment method.

That is, the resin clip 6 is attached to the guide rail 4.
A rectangular seat plate 6a having a width approximately equal to the width of 7 nori 48 is erected at the center of the seat plate 6a, and has a diameter η- equal to the width of the frontage 4+) of the dovetail @/1a. The columnar part 6b, the warhead-shaped fitting part 6d integrally protruding from the columnar part 61), and the flange 6C formed between the 1 and 1 part 6b (1 and +1 part 6b), Seat plate 6 of this resin clip 6
After inserting the guide rail 4 into the front 1 □ - dovetail Ia and arranging it at a predetermined interval, the guide rail 4 is crushed by heat caulking M
As a result, the guide rails 4 at the front and back of the peripheral edge of the plate 6a are melted, thereby fixing the resin clip 6 integrally to the lower surface of the body of the sticking plate.

However, in the first method for removing the resin clip 6 configured as described above, a predetermined amount of heat is applied from the outside of the peripheral edge of the seat plate 6a by heat caulking during removal time 1, as shown in FIG. When pressure P is applied to CJ, the portion of the guide rail 4 is crushed as indicated by the chain line, and the guide rail 4 is melted at the front and rear of the seat plate 6a by this heat and pressure saw. 4T, but in this case, a build-up part Δ shown by a chain line is also formed on the peripheral edge portion where heat and pressure are applied, and this fixes the 4: Tsuking plate 1 to the floor surface 1. This is the cause of not being able to obtain a sufficient flatness of 1q. Therefore, if you use heat and pressure to fix the clip, do not use a cutter or the like to cut into the built-up part. It is necessary to scrape off 13 'r'J, and work efficiency is extremely low.

(Object of the invention) In this invention, an iron clip can be used in place of the synthetic resin clip described in [e] above, and the clip can be removed easily.
The purpose is to fix the base part of d-1:j on a plate like the above-mentioned Kiraking plate-1- by using M3 sonic or high-frequency welding means.

(Structure and Effects of the Invention) In order to achieve the above-mentioned objects, the method of the present invention uses thermoplastic l11 around the outer periphery of an iron clip formed into an appropriate shape.
The mounting base of the clip coated with 1 resin is installed on the surface to be fixed to the synthetic resin plate, and is crimped to the surface to be fixed by ultrasonic or high frequency welding means, and the thermoplastic resin layer and Plate 1 to The clip is fixed to the play plate 1 by melting and integrating the joint surface with the play plate 1.

5- According to the above method, since the main body portion of the clip is made of iron, its elasticity can be maintained for many years, so that the bonding strength to the mating part does not deteriorate.

In addition, even when the method of this invention is applied to places such as 21:1-ngbrae-1 which are easily covered with mud, water, etc., the outer periphery is covered with a resin layer, so rust and corrosion can occur. will not occur.

Furthermore, according to the method of the present invention, the resin layer having good compatibility with the plate is attached to the mounting base of the plate 1 through, for example, by ultrasonic application T1 or high frequency welding. It has various advantages such as being able to fuse them together and having a high bonding strength.

(Description of an Embodiment) An embodiment of the present invention will be described in detail below with reference to FIG. 3 and subsequent drawings.

3 and 4 show clips to which the method of the present invention is applied.

This clip 10 is made by pressing a steel plate with a predetermined depth into the shape shown in the figure.
Its shape is as follows: a flat seat plate part 10a which becomes the base of N1, a 71-piece 10b integrally formed upright from the center of the seat plate part 10a, and a top side edge of the upright piece IQt+ as described above. A pair of clip pieces 100. IOC! The clip piece 10c is bent into a dogleg shape, and forms the shape of the clip 10.

The outer periphery of the clip 10 configured in this manner has a fourth
Shown in the diagram? t J, the sea urchin is coated with a layer of thermoplastic resin 11.

Although the figure shows only the seat plate portion 10a covered with the layer of thermoplastic resin 11, the entire surface is coated with the resin 11 listed in 6Q.

The coating method is Nine resin.

J: The entire outer periphery of the re-flip is firmly covered by applying powder electrostatic baking to a thermoplastic resin such as ().

Next, an example of the ringing in which the clip 10 configured as described above is fixed to the above-mentioned kicking play 1 by the ultrasonic horn T will be explained.

First, in FIG. 5, the dot iRA of the guide rail 4 is
Partially insert the seat plate of the clip 100 from the end of the child into the container a, and place the clip 10 at a predetermined position IN (Q) while avoiding movement along the longitudinal direction of the vortex.

Next, the tip 12 of the ultrasonic horn is faced to that position, and the tip 12 is pressed against the seat plate 10a.
1 Ultrasonic wave oscillated 1! Particularly J: The seat plate portion 10
The layer of resin 11 covering the outer periphery of a is melted by the vibration of a, and comes into strong pressure contact with the inner bottom surface of the dovetail groove 48 due to the pressing force of its tip 12. However, 1) the resin on the inner bottom surface side of the dovetail groove 48 also melts, and as a result of the melting of both, the layer of resin 11 and the contact surface with the resin constituting the inner bottom surface of the dovetail groove 48 melt 20 in a U-shaped manner. When integrated, the clip 10 is fixed at a predetermined position d in the dovetail groove /'Ia.

Furthermore, according to this processing method, the conventional built-up parts can be placed on both sides.
Q: Completely fixed compared to IJ: It must be fixed without any gagging and with sufficient bonding strength (for the following work such as 1 to rimming). does not require

Further, in the above embodiment, the seat plate portion 10a is formed into a flat plate shape, but for example, if a protrusion or the like is formed on the corner of this plate portion or on its flat plate surface, the seat plate portion 10a may be formed into a flat plate shape. In addition to the adhesion force that accompanies the integration of each molten resin by ultrasonic welding, the anchoring effect caused by the biting of the protrusion (A) results in an even thicker Kr bond strength.
