The present invention relates to a joining method in which a receiving jig having numerous protrusions on its surface is used to join the feather-like parts of pine wood without causing the fluff to fall.

That is, as shown in the sectional view of FIG. 2, the pocket is formed by branching off the pocket cover from the trim body.

のである。 Regarding the covering of the pocket 1, in the past, the pocket was colored in the same color as the other armrests 2, etc. (Note that 3 indicates the skin material.) However, in recent years, as shown in the cross-sectional view of FIG. A pine material 6 consisting of a base fabric 5 of Attempts are being made to release it. In other words, the straight feather-like part 4 made of countless fibers such as polypropylene is connected to the base fabric 5 made of polyethylene etc.
The pine material 6 planted in the pocket 1 is bonded to a base material 7 made of polypropylene or the like which becomes the substrate of the pocket 1.
The purpose is to enhance the decorative effect of the door trim as a whole by using the unique aesthetic appearance of the feather-shaped portion 4 and the sense of space that is common to the floor carpet.

を以て瞬時に接合されるのである。 Now, in order to cover the pocket 1 as described above, the mat material 6 having the feather-like portions 4 must be joined to the base material 7 of polypropylene or the like.
It is conceivable to use a high-frequency welder or an ultrasonic welder for this joining operation, but the former high-frequency welder uses a flat blade to perform welding, which inevitably causes hair to fall. In addition, in the conventional ultrasonic welder shown in Fig. 4, although a vibration amplification means can be attached and there is no problem in terms of capacity, the feather-like part 4 at the joint part falls down, and there is a serious problem. This results in poor appearance. That is, in Figure 4, 8
9 indicates the horn of an ultrasonic welder, and 9 indicates a receiving jig with a flat surface. A base material 7 made of polypropylene and a mat material 6 are placed between the horn 8 and the receiving jig 9, and both are heated by ultrasonic welding. They are joined instantly using the large amount of energy generated by vibration.

である。 However, in such a welding method, since the surface of the receiving jig 9 is flat, ultrasonic bonding is performed with the feathered portions 4 pressed down, and therefore, in the finished state after joining, the feathered portions 4 The fibers fall down and remain fused to the base fabric 5. Therefore, at first glance, this location appears to be a welded location having the same length as the tip of the horn 8, resulting in a significant appearance defect.

こと及び接合強度を十分に維持することにある。 The present invention was made in view of the above-mentioned problems and provides an advanced joining method.The purpose of the present invention is to maintain the original beauty of the feathered part without causing any change in the appearance of the joined part. The purpose is to make it possible to maintain sufficient bonding strength.

にしたものである。 For this purpose, the ultrasonic welder joining method according to the present invention uses a jig having numerous protrusions on its surface as a receiving jig facing the horn of the ultrasonic welder, and pine feathers are attached to the protrusions side. The shaped part side is applied to join the pine material to the base material.

(In addition, the same members or the same symbols as those in FIGS. 1 to 4 are given.) In the present invention, the ultrasonic welder itself is no different from the conventional one, but the ultrasonic welder The surface of the receiving jig 10 facing the welder's horn 8 is not just a flat surface like the conventional one, but has numerous protrusions 11. This protrusion 11 is made up of a large number of needle-like protrusions, and has a shape similar to a sword mountain used in flower arrangement. That is, like a conventional receiving jig, the feathered part 4 is pressed with a flat surface and the horn 8 is
Rather than facing the protrusion 11 of the method of the invention
contacts the base fabric 5 of the pine material 6 in a so-called pinpoint manner without pushing down the feather-like portion 4 in any way. Then, this base cloth 5 made of polyethylene or the like is pressed against a base material 7 made of polypropylene or the like and welded and bonded by ultrasonic vibration.

This was done by focusing on the fact that it is not necessary to press flatly, and in order to prevent the feather-like part 4 at the joint location from being pushed down by the receiving jig 10, the surface of the receiving jig 10 is The base fabric 5 of the pine material 6 is placed on the base material 7 facing the horn 8 as countless pinpoints.
It is designed to be fixed by welding.

のである。 As a result, by simply changing the shape of the jig, it is possible to obtain the same bonding strength as bonding using a conventional ultrasonic welder.Moreover, the feather-like portion 4 does not fall down at all, so it is easy to check where the weld is being made. It cannot be distinguished from the appearance, the luxurious beauty inherent to the feathered portion 4 can be maintained, and it matches the feeling of automobile users with progressive tastes.
