Description

Technical Field

[0001] The present invention relates to an outsole of a shoe, and more particularly, to a three-dimensional outsole having a pattern with improved quality and durability and a shoe including the same. Background Art

[0002] In order to beautifully decorate the appearance, various textures (patterns, graphics, shapes, etc.) are formed on an outsole, which is one of the components of a shoe. Korean Patent Publication No. 10-2002-0078676 (ethylene vinyl acetate sole formed with a printed texture layer) discloses a technique of attaching a film with a texture formed thereon to the outsole, and Korean Patent Publication No. 10-2001-0000538 (method of indicating sole patterns) discloses a technique of painting a texture on the outsole.

[0003] However, in the case of attaching a film or painting in order to form a texture on the outsole, as the user wears and uses the shoes, the film or the paint peels off.

[0004] Moreover, in the case of attaching a film or painting in order to form a texture on the outsole, a beautiful texture is not formed, which may be a factor that hinders the aesthetic sense of the user. Summary of the Invention

[0005] Accordingly, the present invention is proposed in consideration of the above problems, and an object of the present invention is to provide a three-dimensional outsole having a pattern with improved quality and durability and a shoe including the same, which can prevent the pattern from peeling off or being damaged even after use while enhancing the aesthetic sense of the user.

[0006] In the three-dimensional outsole with improved pattern quality and durability according to the present invention, a dye penetrates into fine pores formed on the inner or outer surface of a shoe outsole having a three-dimensional shape and is fixed to form a pattern.

[0007] Here, the depth at which the dye penetrates into the fine pores and is fixed is 0.08 mm to 0.12 mm.

[0008] Moreover, the dye penetrates into the fine pores by vacuum adsorption.

[0009] In addition, after the dye is digitally printed on a thermoplastic plate, the thermoplastic plate printed with the dye is heated to be flexible, and the softened plate is attached to the surface of a shoe outsole having a three-dimensional shape by vacuum adsorption and then penetrates.

[0010] Next, a method for manufacturing a three-dimensional outsole with improved pattern quality and durability according to the present invention includes a plate printing step S100, a plate softening step S200, a softened plate outsole vacuum adsorption step S300, and a pattern outsole fixing step S400.

[0011] Next, a shoe including an outsole having a three-dimensional shape with improved texture quality and durability according to the present invention includes any one of the above.

[0012] According to a preferred embodiment of the present invention, a three-dimensional shaped outsole having a texture with improved quality and durability has a dye permeated into the interior of the outsole surface and fixed thereon, thereby forming a beautiful and three-dimensional outsole texture.

[0013] Next, according to a preferred embodiment of the present invention, a three-dimensional shaped outsole having a texture with improved quality and durability has a plate softened by a vacuum closely attached and adhered to the surface shape of the outsole, thereby further improving the texture quality and texture forming effect.

[0018] Before specifically describing embodiments according to the present invention, the present invention is not limited to the following detailed description or the configurations shown in the drawings, and can be used or implemented in various ways.

[0019] In addition, it should be understood that the expressions or terms used in this specification are for illustrative purposes only and should not be construed as limiting.

[0020] That is, expressions such as "mounted", "arranged", "connected", "joined", "supported", and "combined" used in this specification, as long as they do not indicate or limit other expressions, are used as broad expressions including direct and indirect mounting, arrangement, connection, joining, support, and combination. The expressions "connected" and "joined" are not limited to physical or mechanical connection or joining.

[0021] Also, in this specification, terms indicating directions such as upper, lower, downward, upward, rear, bottom, front, and back are used for the purpose of explaining the drawings. However, such terms represent relative directions for the pictures for convenience (when viewed normally). Regardless of any form, these terms indicating directions should not be considered to limit or restrict the present invention to the literal meaning.

[0022] In addition, terms such as "first", "second", "third", etc. used in this specification are only for explanation and should not be considered to imply relative importance.

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0024] Figure 1 It is a reference diagram showing the structure of a shoe to which a preferred embodiment of the present invention is applied. The outsole (hereinafter referred to as "outsole") having a three-dimensional shape with improved texture in terms of quality and durability according to a preferred embodiment of the present invention can be applied to various shoes such as sports shoes, hiking shoes, and soccer shoes. However, preferably, as Figure 1 shown, most preferably it is applicable to a soccer shoe 30.

[0025] This is because, in the case of the soccer shoe 30, in intense soccer games, in order to improve the athletic performance and safety of the wearer, i.e., the soccer player, rivets 22, etc. are attached. It has a three-dimensional shape and, unlike ordinary elastic shoes, includes an outsole 20 formed of a hard plastic material.

[0026] In other words, as Figure 1 shown, the soccer shoe 30 generally includes an upper, i.e., a shoe upper 10, and a sole, i.e., an outsole 20.

[0027] The shoe upper 10 includes a toe cap 12, a front end of the shoe upper 17, a lace loop 13, a shoelace 14, a tongue 11, a shoe waist 19, a shoe opening 15, and a rear part 16.

[0028] The toe cap 12 is the part covering the toes, the front end of the shoe upper 17 is the part covering the front side of the foot, and the shoe waist 19 is the part strengthening the instep and wrapping the heel.

[0029] Also, the tongue 11 prevents the foot from tilting towards the buckled part when wearing the shoe, the shoe opening 15 is the part of the entrance of the shoe, and the rear part 16 is the part strengthening the back of the heel.

[0030] And the lace loop 13 is the hole through which the shoelace 14 enters.

[0031] The outsole 20 is the part where the bottom 24 contacts the ground. The outsole 20 includes rivets 22 that protrude from the bottom 24 of the outsole 20 and are inserted into the ground to improve the adhesion to the ground.

[0032] The rivet 22 and the outsole 20 are integrally formed. According to the user's choice, in order to enable the rivet 22 to be combined with the outsole 20, a coupling hole is formed at the bottom 24 of the outsole 20, and the coupling hole is formed with a thread or the like for coupling the rivet 22.

[0033] Therefore, as Figure 1 shown, the outsole 20 of the soccer shoe is different from the outsole of an ordinary shoe having a flat planar shape. The inner and outer surfaces have a three-dimensional shape and are formed of a hard plastic material. Therefore, it is difficult to form patterns. Even if patterns are formed by a film or painting, in the usage environment of a soccer player who engages in intense sports, the attached or painted textures will immediately peel off or be damaged.

[0034] Thus, the present invention aims to provide an outsole 20 and a shoe 30 including the same, the inner and outer surfaces of which have a three-dimensional shape. In the outsole 20 of a soccer shoe formed of a hard plastic material, even during intense sports, the patterns will not peel off or be damaged, and a beautiful appearance can be maintained.

[0035] Figure 2 is a reference diagram showing a state in which patterns 50 with improved quality and durability are formed on the outsole 20 having a three-dimensional shape according to a preferred embodiment of the present invention. As Figure 3 shown, for the outsole 20 according to a preferred embodiment of the present invention, after a dye 40 for forming patterns penetrates and is fixed through the surface pores 28 of the outsole 20 having a three-dimensional shape, an integral pattern is formed on the outsole 20.

[0036] In other words, through the fine pores on the surface of the outsole 20, the dye 40 penetrates into the interior of the outsole 20 surface and is fixed, thereby forming a texture.

[0037] Therefore, for the shoe 30 according to a preferred embodiment of the present invention, since the dye 40 penetrates into the interior of the outsole 20 surface and is fixed, even if the surface of the outsole 20 is worn, a beautiful pattern can be maintained.

[0038] Here, preferably, through the fine pores on the surface of the outsole 20, the depth (h) at which the dye 40 penetrates inward is 0.08 mm to 0.12 mm from the surface of the outsole 20.

[0039] This is because, in the case of less than 0.08 mm, as the surface of the outsole 20 is worn, part of the pattern or color is damaged or the penetration depth is low, so that the color desired by the user cannot be exhibited. In the case where the dye penetration depth is more than 0.12 mm, in order to make the dye penetrate more than 0.12 mm, high pressure or temperature is required, and thus problems such as low productivity of the product and low quality of the outsole 20 formed of hard plastic may occur.

[0040] Further, the outsole 20 according to the preferred embodiment of the present invention is formed of a transparent or translucent material, and fine air holes 28 connected to each other in a three-dimensional form are formed on the surface of the transparent or translucent outsole 20.

[0041] Therefore, the dye 40 penetrates into the fine air holes 28 connected to each other in a three-dimensional form and is fixed, thereby forming a pattern. Thus, the pattern 50 formed on the outsole 20 according to the preferred embodiment of the present invention exhibits a three-dimensional beautiful color and shows the same beautiful color no matter from which side it is viewed.

[0042] In addition, the dye 40 fixed to the fine air holes 28 connected to each other in a three-dimensional form is fixed like an adhesive, so the fixing effect of the dye 40 is further improved.

[0043] Hereinafter, with reference to Figure 4 ..., the manufacturing process of the outsole 20 having a beautiful color and formed with a pattern 50 with improved durability will be described.

[0044] In other words, Figure 4 is a process flow chart showing the steps of forming a pattern with improved quality and durability on the outsole having a three-dimensional shape according to the preferred embodiment of the present invention. The process generally includes a plate printing step S100, a plate softening step S200, a vacuum adsorption step S300 for the softening plate outsole, and a pattern outsole fixing step S400.

[0045] According to the user's selection, in the plate printing step S100, the plate softening step S200, the vacuum adsorption step S300 for the softening plate outsole, and the pattern outsole fixing step S400, a preheating step of a vacuum adsorption device (not shown) may further be included before the plate softening step S200.

[0046] The plate printing step S100 includes the step of coating the pattern 50 formed on the outsole 20 with a dye on a plate formed of a thermoplastic resin and shaped into a thin plate. Various methods such as digital printing can be used for the method of coating the pattern with the dye.

[0047] Next, the plate softening step S200 includes the step of placing the plate coated with the pattern on the outsole 20 of a transparent or translucent material and then softening the plate using a heating device.

[0048] The reason for softening the plate in this way is that since the outsole 20 has a three-dimensional shape, the plate needs to be softened to have flexibility and closely adhere and attach to the surface of the outsole 20 having a three-dimensional shape in a form conforming to the shape.

[0049] Next, the vacuum adsorption step S300 of the softening plate outer sole includes the step of making the softening plate closely adhere and attach in a form conforming to the surface shape of the outer sole 20 by using a vacuum adsorption device.

[0050] In the vacuum adsorption step S300 of the softening plate outer sole, the surface of the softening plate and the surface of the outer sole 20 are closely adhered and attached to the softening plate and the outer sole 20 located in a closed space by vacuum.

[0051] Herein, according to the user's choice, the vacuum adsorption step S300 of the softening plate outer sole can be divided into a first vacuum adsorption step S300 of the softening plate outer sole and a second vacuum adsorption step S300 of the softening plate outer sole for use.

[0052] In other words, the first vacuum adsorption step S300 of the softening plate outer sole includes the following steps: making the softening plate slowly adhere to the surface of the outer sole 20 with a low vacuum pressure, so that the softening plate completely adheres to the surface of the outer sole 20, and completely removing air and the like in the vacuum chamber.

[0053] Next, regarding the second vacuum adsorption step S300 of the softening plate outer sole, if the inside of the vacuum chamber is in a completely vacuum state, the dye 40 penetrates into the internal pores of the outer sole 20 surface by 0.08 mm to 0.12 mm through a high vacuum pressure.

[0054] Next, in the step S400 of fixing the patterned outer sole, after the dye 40 penetrates into the internal pores 28 of the outer sole 20 surface by 0.08 mm to 0.12 mm through the high vacuum pressure as described above, the dye 40 is hardened and fixed in the internal pores 28 by high temperature.

[0055] Regarding the step S400 of fixing the patterned outer sole, the user can, according to the choice, perform together a heat convection step and a dye discharging step of a certain dye 40 for fixing the entire surface of the outer sole 20.

[0056] The manufacturing process of the pattern 50 of the outer sole 20 according to the preferred embodiment of the present invention improves the formation effect of the pattern 50 through the above process, and forms a beautiful and three-dimensional pattern 50.

[0057] Above, the preferred embodiments of the present invention have been described, but the present invention can use various variations, changes and equivalents. It should be clear that the present invention can be appropriately deformed for the same application of the embodiments. Therefore, the above description does not limit the scope of the present invention defined by the boundaries of the claims.

[0058] Industrial applicability

[0059] The present invention can be used for shoes and the like.
