Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of attaching an ornament to a vehicle wheel cover.

BACKGROUND ART Conventionally, in a wheel cover for a vehicle, a circular concave receiving groove is formed approximately in the center of the outer surface of the cover body, and an ornament is adhesively fixed inside with double-sided adhesive tape.
As shown in the figure, when the cover body 1 is made of a transparent synthetic resin, the ornament is attached by drawing the ornament 2 on the inner surface approximately in the center with a hot stamp and covering it with a colored coating film 3. ing.

Problems to be Solved by the Invention However, these wheel covers are not yet fully satisfactory decoratively because the ornaments lack depth in color tone.

In order to make the color of this ornament look deeper, the cover body should be made of transparent synthetic resin, and separately molded ornaments should be attached to the inner side. It is extremely time consuming to apply a sealant in an airtight manner that prevents dirt, water, etc. from entering.

Means for Solving the Problems In the method of attaching an ornament to a vehicle wheel cover according to the present invention, a disc-shaped ornament is attached to a cover body made of transparent synthetic resin with an annular rib protruding from approximately the center of the inner surface. The ornament is installed in a fixed manner by placing it inside the annular rib and rotating it horizontally with the cover body.A liquid sealant is applied to the back of the ornament, and the sealant is applied by the centrifugal force caused by the rotation. It is made to migrate to the circumferential surface of the annular rib and harden.

Function: In this method of attaching an ornament, the cover body on which the ornament is placed is rotated while the liquid sealant that fixes the ornament is applied to the edges of the ornament.The centrifugal force generated by the rotation allows the liquid sealant to be transferred to the periphery and harden. This eliminates the need to trace and apply the sealant to the periphery of the ornament, and since the sealant is pressed against the annular rib by centrifugal force and cured, the sealant is brought into close contact with the ornament, making it possible to securely fix the ornament in an airtight manner. Since other ornaments can be seen through the thickness of the cover body made of resin, the depth of the color tone is increased and the cover can be installed as an excellent decorative item.

An example will be described below with reference to FIGS. 1 to 4.

In this vehicle wheel cover, a cover body 10 is formed into a disc shape from a transparent synthetic resin such as polycarbonate resin or methyl methacrylic resin.

A plurality of annular ribs are protruding from its inner surface.
Of these, those located closer to the outer periphery are the cover body lO
The retainer is designed to reinforce the cover body and attach the cover body lO to the tire wheel. Further, the annular rib 11 located on the inner side of the cover body 1
In addition to being reinforced with No. 0 reinforcement, the ornament 12 is received and fixed therein as shown in FIGS. 1 and 2. The inner surface from the tip of the annular rib 1' 1 to the periphery of the cover body 10 is subjected to pretreatment such as annealing and degreasing, and then a coating layer 13 is formed with a colored paint mixed with fine metal powder. The inner side of the annular rib 11 is formed transparent so that it can be seen through from the outer surface side. On the inside thereof, an ornament 12 can be attached, for example, a disk-shaped object made by printing a predetermined pattern or symbol on one side of an aluminum plate, or by stamping and coloring the plate. For this installation, press or suction the ornament 12 with a rotatable pressing part or vacuum ■, place the inside of the annular rib 11, then rotate the whole thing horizontally, and harden it with a nozzle N on the periphery of the back surface of the ornament 12. A liquid sealant 14 having a rubber-like elasticity of 7 is discharged and adhered. The sealing agent 14 moves and adheres to the inner surface of the annular rib 11 due to centrifugal force as the sealant 14 rotates, and hardens over the u-stroke between the ornament 12 and the annular rib 11. The ornament) 12 can have an extremely deep color tone by providing a ring-shaped seat 15 with a relatively small stand on the inside of the annular rib 11 and maintaining a distance between it and the inner surface of the cover body 10. Can be installed so that it can be seen through. In this case, it is preferable to form the above-mentioned coating layer 13 on the tip end surface of the seat 15, and also to leave a slight gap between the side surface of the annular rib 11 and the periphery of the ornament 12, as shown in FIGS. 1 and 3. Then, the sealant 14 can be filled between the annular rib l'l and the seat 15 so that they are fixed. The spacing can be determined by forming the ornament 12 relatively small as shown in FIG. Can be set at intervals. As the sealant 14, a heat-curing type, a cooling-curing type, or an ultraviolet irradiation-curing type can be used.Also, if a sealant with a color similar to that of the coating layer 13 formed on the inner surface of the cover body 10 is used, the surface of the ornament 12 will be hardened. Even if the sealant 14 protrudes to some extent on the side, it can be made unnoticeable. At a position circumferentially away from the discharge position of the sealant 14, hardening accelerating means such as a pipe P that blows out hot air or cold air and an irradiation lamp E that irradiates ultraviolet rays are arranged as shown in FIGS. 1 to 3. Sealant 1
4 reaches a predetermined discharge amount, the operation can be started. In the case of blowing hot air or cold air, the sealant 14 is forcibly filled into the groove between the annular rib 11 and the seat 15, and the sealant 14, which is transferred by the centrifugal force caused by rotation, is moved between the annular ribs 11 and the seat 15. 11 can be prevented from overflowing to the outside. In particular, it is preferable to blow hot or cold compressed air toward the outer circumferential side on the opposite side to the rotation direction. In addition, since the part of the cover body 10 where the ornament 12 is attached is transparent when irradiated with ultraviolet rays, it is possible to accelerate curing by irradiating ultraviolet rays from the outer surface side as shown in FIG. Before placing the ornament 12, liquid sealant is filled in the groove between the ring rib 11 and the catch seat 15, and when it is still fluid, the ornament 12 is placed and the nozzle is further removed. It is also possible to discharge the sealant 14 from N and fix it. Note that the rotation speed of the cover body lO and the ornament 12 described above is the same as that of the sealant 1.
What is necessary is just to adjust according to the viscosity when discharging 4.

When attaching the ornament in this way, the sealant 14 is discharged from one place on the periphery of the ornament 12, and the cover body 1 is
By rotating the entire ring 0, the sealant 14 can be transferred and attached to the entire circumference of the annular rib 11, so that the sealant 14 sticks to the inner surface of the annular rib 11 due to the centrifugal force caused by the rotation of the whole, and also covers the entire circumference of the annular rib 11. Since it is also filled into the grooves on the inner surface of the main body 10 and hardened, it is uniformly hardened in close contact with the periphery of the ornament 12 without creating a gap.

Note that if a silicone-based, urethane-based, or synthetic rubber-based sealant is used as the sealant 14, which exhibits rubber-like elasticity when cured, even if the cover body 10 expands and contracts, it will absorb the expansion and contraction and make the ornament. By keeping the ornament 12 airtight, the ornament 12 can be securely attached without being partially peeled off or detached.

Effects of the Invention As described above, according to the method for attaching an ornament to a vehicle wheel cover according to the present invention, another ornament can be securely and easily attached to the inner surface of the cover body using a sealant, and the ornament can be easily attached. The deep color tone makes it possible to form a wheel cover for a vehicle that is highly decorative.
