Description

Detailed Description of the Invention The present invention relates to a molding used for decoration and protection in vehicles, furniture, buildings, etc., which is particularly easy to attach and detach, and which resists adhesion due to vibration or long-term use. The aim is to provide a mall that does not degrade in quality.

Taking the side moldings of automobiles as an example, this type of molding is increasingly made of synthetic resin, and there is also a trend toward larger sizes due to design requirements and protection functions. .

Double-sided adhesive tape with pressure-sensitive adhesive has become common as a means for attaching this synthetic resin molding.

By the way, when the above-mentioned double-sided adhesive tape is used, as the size of the molding becomes larger, the weight increases and the shrinkage rate over time becomes larger in size, and the molding tends to peel off from the ends, and in particular, there is a problem that the molding lifts up from the terminal part. .

Therefore, a hollow molding was developed as a countermeasure for this problem, but when pressing the hollow molding and adhering it to an adhesive such as a car body using double-sided tape, the existence of the hollow part creates a sufficient pressing force on the center of the back side of the molding. Therefore, since complete adhesion is not achieved over the entire back surface, it is susceptible to expansion and contraction of the molding due to seasonal or temperature differences between day and night, and molding distortion. The problem of peeling still remains.

On the other hand, there is a growing tendency for moldings to become fashionable in automobiles and the like, and there is a demand for using moldings with different shapes, colors, etc. depending on the occasion.

However, with the double-sided adhesive tapes mentioned above, once the moldings are removed, the adhesive strength decreases and reuse is impossible; however, with adhesive tapes, the adhesive hardens and adheres to the moldings and car body after being peeled off. is not easy to remove.

This invention has been made in view of the above-mentioned circumstances, and its gist is that one of a pair of opposing hook-and-loop fasteners is joined to the back surface of the molding main body, the other is joined to the molding base surface, and the above-mentioned pair of surfaces to be engaged are bonded. The molding is characterized in that the molding body is detachably attached to the molding base via a fastener.

Furthermore, the second invention is a method in which one of a pair of opposing hook-and-loop fasteners is bonded to the back surface of the molding main body, and the other surface fastener is attached to the surface of the molding base, which has an adhesive layer on the back surface and can be attached to an adherend. A molding main body is detachably attached to a base body or an adherend via the integral hook-and-loop fastener that is formed on the body surface by bonding or molding and is engaged, and a wing piece that covers the hook-and-loop fastener is attached to the side of the molding main body. It's in a mall that has a lot of character.

An embodiment of the invention will be described with reference to the drawings. FIG. 1 shows a cross section of an embodiment of the molding of the invention, and the molding consists of a molding body 1 and a molding base 2. As shown in FIG.

The molding body 1 is made of vinyl chloride resin and is formed into a long length by extrusion molding, and the surface thereof has a desired shape, color tone, and pattern (for example, a grain pattern), and the back surface has one of a pair of hook-and-loop fasteners. A hook-and-loop fastener 3a is bonded via an adhesive layer 4.

The molding base 2 is made of vinyl chloride resin, and the other hook-and-loop fastener 3b is bonded to its upper surface via an adhesive layer 5, and one surface of a double-sided adhesive tape 6 is bonded to its lower surface.

7 is the release paper of the double-sided adhesive tape.

In this invention, the molding is not limited to one made of synthetic resin;
It may be made of any material such as rubber, leather, metal, etc.

Further, the molding body may be solid, hollow, or foamed.

A hook-and-loop fastener is a so-called magic fastener, and is made up of a pair of sheets, for example, with many loops made of fibers on one side and many hooks made of fibers on the other side. The loop is formed and the hook is engaged with the hook.

To join the hook-and-loop fastener to the molding body or base, in addition to bonding with the adhesive layer 4.5 as shown in the figure, the hook-and-loop fastener and the molding body or base are simultaneously extruded from a die during extrusion molding, and the molten resin of the molding is It may also be integrally molded by crimping it onto a hook-and-loop fastener.

In addition, immediately after extruding the molding, the hook-and-loop fastener may be pressed and integrated, or after the molding is extruded, the surface to which the hook-and-loop fastener is to be joined may be heated and melted by an appropriate method.
A hook-and-loop fastener may be crimped and integrated.

Furthermore, welding can also be performed by high frequency welding or the like.

As shown in FIG. 2, the attachment to the adherend is done in advance by attaching the hook-and-loop fastener 3a between the molding body 1 and the molding base 2.

3b bonded together, peel off the release paper 7 formed on the back of the molding and attach it to the adherend 8 at a predetermined position, or first attach the molding base 2 to the adherend 8. After mounting, the molding body 1 is joined to the molding base 2.

The molding body and the molding base body can be joined together by simply pressing from the upper part of the molding body, and the hook-and-loop fasteners can easily engage with each other to fix the molding to the adherend.

Note that it is preferable that the hook-and-loop fastener be formed to be slightly narrower than the molding width.

FIG. 3 shows a cross section of another embodiment of the molding of the present invention, and the molding consists of a molding body 1A and a molding base 2.

The molding body 1A is made of vinyl chloride resin, is formed into a long length by extrusion molding, and has a desired shape, color tone, and pattern (for example, a grain pattern) on its surface.

Five wing pieces 1a are provided downwardly on both sides.

On the back side is one of the pair of hook and loop fasteners.
3a are joined via an adhesive layer 4.

The molding base 2 is bonded to its upper surface via the other hook-and-loop fastener 3b or the adhesive layer 5, and its lower surface is bonded to one surface of a double-sided adhesive tape 6.

7 is the release paper of the double-sided adhesive tape.

FIG. 5 shows still another embodiment of the present invention, in which the structure of the molding body 1B is the same as that of the previous embodiment, but it does not have a molding base, and the other hook-and-loop fastener 3b is attached via an adhesive layer 5. It is directly bonded to the adherend.

When attaching one side of the hook-and-loop fastener directly to an adherend, work efficiency is improved if an adhesive layer 5 as shown in FIG. 3 is formed on the hook-and-loop fastener in advance.

Examples of the adhesive layer include a double-sided adhesive tape, a thin synthetic resin layer formed on the back side of a hook-and-loop fastener and then attached with a double-sided adhesive tape, or an adhesive coating.

Note that one hook-and-loop fastener may be formed in advance on the adherend side.

The molding of the embodiment shown in FIG. 3 is attached to an adherend by attaching the molding in which the surface fasteners 3a and 3b of the molding body 1A and the molding base 2 are joined together in advance on the back side of the molding, as shown in FIG. Peel off the formed release paper 7 and remove the adherend 8.
Alternatively, the molding base 2 is first mounted on the adherend 8 and then the molding body 1A is joined to the molding base 2.

In the case of the molding of the embodiment shown in FIG. 5, first, a hook-and-loop fastener 3b with an adhesive layer provided on the back surface is adhered to a predetermined location of the adherend 8, and the back side of the molding body 1B is placed on the hook-and-loop fastener 3b. The other hook-and-loop fastener 3a provided at the is positioned, and the molding main body 1B is attached to the adherend.

The pair of hook-and-loop fasteners 3a, 3b can be engaged simply by pressing from the upper part of the molding body 1, and the hook-and-loop fasteners 3a, 3b can easily engage with each other to secure the molding body 1 to the adherend 8. I can do it.

When the molding according to the present invention is attached to the adherend 8, the wing pieces 1a protruding from the side of the molding body are formed so as to come into contact with the surface of the adherend 8.

In the molding of the present invention that is attached in this way, even if the molding body is deformed due to temperature changes or molding distortion, this deformation will be prevented by the adhesive because the hook-and-loop fastener is interposed between the molding body and the adherend. Since the hook-and-loop fastener absorbs the adhesive without affecting the adhesive layer, there is no possibility of the adhesive strength decreasing and peeling.

In addition, even when vibrations are applied to the car body, which is the adherend, as in the case of automobiles, this vibration is absorbed by the hook-and-loop fastener and is not transmitted directly to the molding, preventing resonance, and does not affect the adhesive force. .

Furthermore, since the molding body can be easily and reliably attached and removed, if you prepare a wide variety of moldings with different shapes and colors, you can replace them as needed, and enjoy fashion according to your mood at the time. be able to.

Furthermore, since the wing pieces protruding from the side of the molding body contact the surface of the adherend and partially cover the hook-and-loop fastener, the hook-and-loop fasteners 3a and 3b are completely invisible from a decorative standpoint; Since there is no gap between the molding and the adherend, it is possible to prevent dust from entering, and the wing pieces
It also has the effect of preventing the penetration of ultraviolet rays, etc., which accelerate aging of the adhesive layer, and the initial adhesion of the molding to the adherend can be maintained for a long period of time.
