DETAILED DESCRIPTION

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

First, the individual steps of a metal decoration manufacturing method according to the present invention will be described according to the sequence of a process.

FIG. 2 shows a protocol decoration 10 that is injection-molded to manufacture a metal decoration according to the present invention. The injection molding is designed to manufacture a product by injecting a plastic or metal material into a mold having a predetermined shape. However, the protocol decoration 10 is not limited to injection molding, and may be manufactured by a punching, pressing, cutting or machining process or by combining one or more of these processes with injection molding. Hereinafter, the following description will be given on the assumption that the protocol decoration 10 is injection-molded.

In the case where the protocol decoration 10 is injection-molded, the protocol decoration 10 is molded into an integrated product in which a first base decoration 12 and a second base decoration 14 are connected by a runner R′, as shown in the drawing.

The base decorations each include a logo to be imprinted on a final product such as a handbag. The first logo 12a of the first base decoration 12 is three-dimensional (3D) letters of “kate spade.” The second logo 14a of the second base decoration 14 is a combination of 3D letters of “NEW YORK” and a spade shape. These logos are only examples. In the present invention, the “logo” may include any trademark, trade name, product name, country of origin, and a verification or certification mark. In addition, the logo includes one or more letters, shapes, symbols, colors and/or the combination thereof, and is not particularly limited to any type of elements.

The first base decoration 12 and the second base decoration 14 are rectangular flat plates, but are not limited thereto. The first logo 12a is formed on the lower portion of the first base decoration 12, and an injection bridge 122 formed in an injection molding process is attached to the protruding lower portion of the first logo 12a. The second logo 14a is formed on the upper portion of the second base decoration 14, and an injection bridge 142 formed in the injection molding process is attached to the protruding upper portion of the second logo 14a.

FIG. 3A shows a state in which the first base decoration 12 and the second base decoration 14 have been separated and removed from the protocol decoration 10 and unnecessary injection bridges 122 and 142 have been removed. First holes 126 are formed on both sides of the upper portion of the first base decoration 12, and second holes 146 are formed on both sides of the lower portion of the second base decoration 14.

FIG. 3B shows views illustrating the rear surfaces of the first base decoration 12 and the second base decoration 14 from which the injection bridges 122 and 124 have been removed in FIG. 3A.

Long or short first pins 120a are formed on the rear surface of the first logo 12a of the first base decoration 12. A total of 18 first pins are formed for 9 letters by arranging long and short pins in a set for each of the letters constituting the first logo 12a. Similarly, long or short second pins 140a are formed on the rear surface of the second logo 14a of the second base decoration 14. A total of 6 second pins 140a are arranged at appropriate locations at intervals. This is performed by taking into consideration the size and overall balance of the second logo 14a. That is, the size, number and arrangement of the pins 120a or 140a are appropriately changed by taking into consideration the size, weight and balance of the corresponding logo, and the illustrated embodiment is merely an example.

It is obvious that the first and second pins 120a and 140a have been already formed on the protocol decoration 10 of FIG. 2.

In the metal decoration manufacturing method of the present invention, a plating process is performed on the first base decoration 12 and second base decoration 14 of FIG. 3A. Any of electroplating, electroless plating, vacuum plating, electrodeposition coating, and the like may be used as the plating process. The plating process may be performed not only on the separated decorations of FIGS. 3A-3B but also on the integrated protocol decoration 10, and the sequential positon of the plating process does not limit the scope of the present invention. The plated base decorations have beautiful appearances each having a metallic luster.

Thereafter, in the present invention, a plate 4 is used as a member for intermediately imprinting or transplanting a base decoration(s).

FIG. 4A shows the plate 4 for coupling with the base decorations of FIGS. 3A-3B. The plate 4 is manufactured in a rectangular shape as a whole, but is not limited thereto.

The plate 4 has a first logo accommodation portion 4a for the planting or transcription of the first logo 12a formed on the upper portion thereof and a second logo accommodation portion 4b for the planting or transcription of the second logo 14a formed on the lower portion thereof. The first logo accommodation portion 4a is composed of empty spaces consisting thin channels penetrating the plate 4 to form the “kate spade,” and the second logo accommodation portion 4b is composed of spaces consisting of two empty rectangular channels instead of the letters “NEW YORK” and an empty space in the shape of a spade. That is, the shape of each of the logo accommodation portions may vary depending on the size and arrangement of the logo. For example, the logo accommodation portion may be appropriately formed as spaces corresponding to respective letters or as a small space accommodating a letter string composed of a plurality of small letters.

Each of the channels or spaces constituting the first logo accommodation portion 4a needs to have the same size as or a slightly smaller size than each of the letters “k,” “a,” “t,” “e,” “s,” “p,” “a,” “d,” and “e” of the first logo 12. In the same manner, each of the three spaces constituting the second logo accommodation portion 4b needs to be equal to or slightly smaller than each of the spaces formed by the character strings “NEW” and “YORK” and the shape “” Otherwise, in the coupling process to be described later, the first logo 12a and the second logo 14a are not coupled to the plate 4 securely, and pass through the spaces of the logo accommodation portions or are loosely coupled to the plate 4, so that subsequent processes become difficult and the probability that a defect occurs increases.

FIG. 4B is a view of the rear surface of the plate 4 showing the temporary coupling of the first base decoration 12 and the second base decoration 14 to the plate 4 of the present invention. An operator aligns and then inserts the first logo 12a with and into the first logo accommodation portion 4a and the second logo 14a with and into the second logo accommodation portion 4b manually or using an arm of an automated NC machine, thereby temporarily coupling the two members to each other. The plate 4 is preferably manufactured in a size that accommodates the first and second logos 12a and 14a as well as the first and second base decorations 12 and 14, which are base materials to which the first and second logos 12a and 14a are attached. In this state, the first and second fins 120a and 140a are erected and exposed upward.

Next, a coupling process using the plate 4 of FIGS. 4A-4B will be described. The coupling process may be considered to be a process of integrating, transcribing, or transplanting the first logo 12a and the second logo 14a, constituting the theme of the metal decoration, onto the plate 4.

FIG. 5 is a perspective view showing a press machine 5 for performing the coupling process of the present invention.

The press machine 5 includes an upper press part 50 and a lower worktable 60.

As shown in the bottom surface of the press part 50, a protruding rectangular pressing portion 54 is formed on the bottom surface formed of a flat base 52. Pinholes 56 are formed in the pressing portion 54. The pinholes 56 are drilled in two rows in the illustrated example. The upper pinholes 56a are intended to accommodate the first pins 120a, and the lower pinholes 56b are intended to accommodate the second pins 140a. Accordingly, the interval and arrangement of the pinholes 56 need to be formed to match those of the first and second pins 120a and 140a. It is preferable that the diameter of the pin holes 56 is at least equal to or slightly larger than that of the pins in order to tightly accommodate the pins. Rods 58 each extending in a circular column shape are formed on both sides of the pressing portion 54.

In the worktable 60, the plate 4 coupled with the decoration logos is seated in a mounting groove depressed into a support surface 62. Accommodation holes 66 configured to accommodate the rods 58 are formed long on both sides of the mounting groove.

The plate 4 of the present invention is seated in the mounting groove with the bottom surface of FIG. 4B facing upward.

When an operator operates the press machine 5, the press part 50 descends, so that the first and second pins 120a and 140a are closely inserted into the respective pinholes 56 of the pressing portion 54 and then the flat surface of the pressing portion 54 presses the first and second base decorations 12 and 14. Accordingly, the first logo 12a is inserted and fixed into the first logo accommodation portion 4a, and the second logo 14a is inserted and fixed into the second logo accommodation portion 4b. In this section, the term “fixed” means that the first and second logos 12a and 14a are pressed into the first and second logo accommodation portions 4a and 4b in a temporarily coupled state and, thus, are not separated therefrom or are not deformed therein unless a large force is applied. The term “fixed” does not mean that the first and second logos 12a and 14a are permanently imprinted on the plate. During this process, the rods 58 are inserted into the accommodation holes 66. The accommodation holes 66 may allow the pressing portion 54 to transmit force evenly while moving downward without shaking through the guidance of the rods 58, and may also serve as stoppers.

When the coupling process is completed through the above operations, the operator collects the plate 4 to which the first and second logos 12a and 14a are fixed. The square border forming the outer edge of the pressing portion 54 may press the periphery of the logos of the first and second base decorations 12 and 14 to allow easy separation. Accordingly, the operator manually separates the remaining portions excluding the first and second logos 12a and 14a.

FIG. 6 shows the front and bottom surfaces of the plate 4 after the above coupling process. The first and second pins 120a and 140a of the first and second logos 12a and 14a are maintained without being damaged or separated.

The “plate” of the present invention may be manufactured in a curved shape or other three-dimensional shapes, regardless of the term, as long as the first and second logos 12a and 14a can be planted thereonto. Although plastic is suitable for the material of the plate 4, the material is not limited thereto.

The intermediate finished product of FIG. 6 is now “permanently” fixed to rubber, i.e., a material of a handbag, through a final imprinting process.

FIG. 7 is a perspective view of a setting press machine 7 that performs the final imprinting process. The setting press machine 7 includes an upper setting press part 70 and a lower setting worktable 72.

The setting press part 70 includes a setting pressing portion 74 into which an assembly body 8 is inserted.

The assembly 8 includes a mold frame 82, as shown in FIG. 8. A support mold 820 having respective pin holes configured to accommodate the first and second pins 120a and 140a is formed on the mold frame 82. A first elastic washer 84 and a second elastic washer 86 having the same plan-view shape as the support mold 820 are inserted into the support mold 820. The assembly 8 is inserted into the setting pressing portion 74 so that the second elastic washer 86 faces the bottom surface, i.e., the setting worktable 72.

The plate 4 is placed on the setting worktable 72 so that the bottom surface of the plate 4 faces upward and the first and second pins 120a and 140a are accurately aligned with the respective pin holes of the support mold 820 and the first and second elastic washers 84 and 86 exactly in the vertical directions. A mounting groove (not shown) is formed in the setting worktable 72, and the plate 4 is placed therein. A lower support portion embossed with shapes corresponding to the first and second logos 12a and 14a is formed in the mounting groove in advance.

Then, a raw material constituting a material of a handbag or the like, for example, rubber, which is leather, is placed on the plate 4. In this state, when the setting press machine 7 is operated, the setting pressing portion 74 descends and presses the bottom surface of the plate 4. In this case, the first and second logos 12a and 14a coupled to the plate 4 are imprinted on the rubber as if they were printed on the rubber by the reaction force of a lower support portion. That is, the first and second logos 12a and 14a are transcribed from the plate 4 to the rubber. Furthermore, the first and second elastic washers 84 and 86 are separated from the mold frame 82 and attached to the opposite surface of the rubber. The protruding first and second fins 120a and 140a are finished as a flat surface with silicone.

In the state where the first and second logos 12a and 14a are imprinted on the rubber, the plate 4 is in a state identical to a state in which it is temporarily separated from the rubber, so that the operator can easily remove the plate 4 from the rubber. This completes a final product imprinted with the metal decoration of the present invention.

FIG. 9 shows a rubber imprinted with the logos of the present invention, and is the same as described above except that the spade shape is located at the center of the upper portion.

A method for manufacturing a metal decoration is described by synthesizing the individual steps of the present invention described above with reference to the process diagram of FIG. 1, as follows;

First, a protocol decoration is fabricated through an injection process in step S10.

Thereafter, base decorations are provided by removing unnecessary portions from the protocol decoration in step S12.

Thereafter, the base decorations are plated in step S14.

Thereafter, the logos of the base decorations are integrated with a plate by coupling the logos of the base decorations with the plate through a coupling process in step S16.

Thereafter, the logos of the plate to which the logos are coupled are imprinted and fixed onto a material, to which a metal decoration will be finally fixed, through a final imprinting process in step S18.

FIG. 10 shows a protocol decoration according to another embodiment of the present invention, and FIG. 11 shows base decorations that are separated from the protocol decoration of FIG. 10 and then plated. In FIG. 10, the left drawing shows the front surface of the protocol decoration, and the right drawing shows the rear surface of the protocol decoration.

The protocol decoration 10 includes two base decorations, which are identical to each other. Each of the base decorations includes “kate spade,” “NEW YORK,” and a spade shape. In this case, it will be understood that the operation time can be reduced compared to the above-described embodiment.

The preferred embodiments of the present invention have been described above. The gist of the present invention lies in the fact that any logo composed of one or more letters or shapes can be easily and accurately integrated by coupling the logo with a plate, which is an intermediate medium. The present invention is useful when a logo is composed of only one letter or shape, as well as when it is composed of two or more letters or shapes. It will be understood that the present invention is more useful when it is composed of a combination of a long string and a shape, as in the embodiment of the present invention.

Similarly, in the present invention, the same description is applied to a case where there is one base decoration as well as a case where there are three or more base decorations, and the same effects can be expected.

The metal decoration to be imprinted may include one or more letters, characters, shapes and/or symbols, and may be formed into various three-dimensional shapes, such as a curved shape and a protrusion-depression shape, as well as a flat plate shape.

According to the present invention, there are provided the effects of easily and economically manufacturing a metal decoration, reducing work man-hours, and improving manufacturing efficiency.
