Definitions
- the present invention relates to a lightweight shoe, and more particularly, to a lightweight shoe and a method of manufacturing the same without a bonding process imparting adhesion and non-slip function, regardless of the shape and shape of the various wearers.
- a shoe protects a person's foot.
- the shoe When a shoe is running or walking, the shoe is blocked from the outside and the foot is protected.
- the foot In modern life, the foot is always protected by shoes, and barefoot walking, which is most suitable for the human body, has become almost impossible.
- barefoot walking shoes Due to these problems, various types of barefoot walking shoes have recently emerged in order to achieve the most suitable barefoot walking for the human body. For example, various types of shoes have been released, such as shoes that support cloud movement through the sole foot pressure by supporting the shoes or foot arches to implement the Maasai walking by enabling cloud movement.
- the shoes are basically shoes, consisting of the outsole, midsole and upper, no matter how lightweight materials are used, the weight of at least 200g, the pedestrian can barely feel bare feet. Therefore, due to the weight of the shoes transmitted through the foot is difficult to achieve the purpose of walking barefoot.
- these shoes are basically bonded using an adhesive for bonding the outsole and the midsole and upper in the manufacture of the shoes.
- These adhesives have many problems as the use of the most environmental pollutants in the shoe industry.
- the outsole is made of natural rubber or synthetic rubber, which is a material that can relatively prevent traction and slip.
- synthetic rubber and natural rubber are not only heavy in general, but also manufactured through a separate process, and thus, the midsole and the adhesive are used using an adhesive, so that the lightweight shoes cannot use the outsole having such a sense of weight.
- the function will not be able to achieve the anti-slip function. Therefore, lightweight shoes have a problem that can only be used in extremely limited places, such as the beach without slipping.
- the present invention has been made in order to solve the above problems, the present invention is manufactured shoes without the bonding process, the light weight and the non-slip and traction force is improved so that the feeling of the shoe wearer for walking or walking when walking or running The aim is to provide shoes.

- the flooring, the insole window has a mesh diameter of 100 to 300 ⁇ m
- the sole is made of polystyrene, styrene-butadiene-styrene block copolymer (SBS), styrene-isoprene-styrene blockco The polymer (SIS), styrene-ethylene, butylene-styrene block copolymer (SEBS) and styrene-ethylene, propylene-styrene (SEPS), or any mixture of two or more.
- the sole is made to be 15 to 40% by weight or less with respect to the total weight ratio of the sole, and the injection molding temperature 120 to 150 degrees and the injection molding time to be molded within 1 to 5 minutes, the upper (20)
- the upper part and the bottom part are combined by performing the sewing (a) in a state in which the edge of the part forming the outer surface of the bottom part is in close contact with the edge of the upper surface of the insole window 34 of the bottom part 30.
- the present invention the step of manufacturing the insole window by cutting the fiber having a mesh structure;
- the insole window is placed on the injection mold, and the injection liquid made of polystyrene is injected onto the mold through an injection machine to form the sole, and the injection liquid penetrates into the mesh structure of the insole window to integrally integrate the sole and the insole window.
- the insole window has a mesh diameter of 100 to 300 ⁇ m
- the sole window is styrene-butadiene-styrene block copolymer (SBS), styrene-isoprene-styrene block copolymer (SIS), styrene-ethylene, butyl Styrene-styrene block copolymer (SEBS) and styrene-ethylene, propylene-styrene (SEPS) any one or a mixture of two or more
- the upper is made of a neoprene system having an elastic resilience of 120 to 150%
- the upper Sewing is made in the state that the edge forming the outer surface of the fold in contact with the top edge of the insole window of the bottom to prevent contact with the ground of the upper.
- the present invention is eco-friendly because there is no use of the adhesive, it is possible to obtain the effect of improving the production capacity of the worker.
- the present invention is made of ultra-lightweight, it is possible to maximize the feeling of walking barefoot there is another effect of maximizing the wearer of the shoe wearer.
- FIG. 1 is a perspective view of the ultra-lightweight shoe without the adhesive process according to the present invention.
- FIG. 2 is a cross-sectional view taken along the line A-A of FIG.
- Figure 3 is a view showing the manufacturing process of the ultra-light shoes according to the present invention.
- FIG. 1 is a view showing an embodiment of a shoe without an adhesive process in one embodiment of the present invention
- Figure 2 is a cross-sectional view taken along line A-A of FIG.
- the ultra-lightweight shoe 10 consists of an upper portion 20 covering the wearer's foot and a bottom portion 30 forming a bottom including an outsole in contact with the ground.
- the upper part 20 is a part to protect the foot so that the basic material is made of a material having an elastic force to provide adhesion with the foot so that there is no additional structure such as a separate strapping. That is, the role of the upper part 20 is that the instep is to maintain the adhesion between the protection and the instep.
- the foot and the adhesion are usually maintained through a separate member such as a strap or a zipper, but in this case, the intact adhesion is maintained only in the vicinity of the strap and the zipper, and the foot or the heel portion separated from the foot is completely Adhesion is not achieved. Therefore, in this case, the shoes are barely peeled off or loosened due to looseness when walking.
- the present invention is to use the elastic material to remove such a problem and to provide a feeling of bare feet by providing a close feeling in contact with the entire foot.
- the elastic material is made of elastic material having excellent resilience, but is made to use a fabric such as neoprene system used in swimwear and the like, and the material such as synthetic fibers and rubber that provides elastic restoring force is not limited.
- first thickness should be more than 2mm. This is to protect the instep from foreign matters and the like. That is, when the thickness is 2mm or less, the outside is easily torn due to an impact or the like, and it is difficult to perform the role as an upper.
- Second, elastic recovery elasticity should be made of 120 to 150% or less. In other words, elastic restoration elastic force should be made to the extent to maintain the comfort close to the wearer's foot. When the elasticity is 120 or less, the elasticity is too small to be inconvenient for the user to wear, and the adhesion to the instep is reduced.
- the elasticity is 150 or more, it is easy to wear and the adhesion of the foot is good, while the pressure applied to the foot is strong, which causes the wearer to feel pressure. Therefore, as the upper elasticity is about 120 to 150%, the convenience of wearing, the adhesion to the instep and the wearer's feeling can be maintained in the best state.
- the tightening piece 22 having a separate elastic so as to form a curve in the instep portion. This tightening piece 22 serves not only to enhance the external aesthetics, but also to assist the upper part to be in close contact with the instep. The tightening piece 22 will be sufficient to couple to the upper surface by sewing or thermocompression.
- the bottom portion 30 has a structure in which the sole 32 in contact with the ground and the sole window 34 in contact with the sole surface are integrally formed without using an adhesive.
- the sole 32 is made of a synthetic rubber, such as natural rubber or butadiene rubber to prevent slipping and to improve the grip strength, and then made the rubber using a mold and then insole 34 to the rubber sole 32 It is used to glue the adhesive.
- a synthetic rubber such as natural rubber or butadiene rubber to prevent slipping and to improve the grip strength
- the sole 32 should be made lighter than conventional rubber soles, and ensures non-slip and traction and adheres to the insole without adhesive. Therefore, in the present invention, while searching for a material and a processing method that satisfies these conditions, a material made of a TPE (Thermo plastic elastomers) -based material was used, but a material that was processed by injection molding was selected.
- TPE Thermo plastic elastomers
- polystyrene styrene-butadiene-styrene block copolymer (SBS), styrene-isoprene-styrene block copolymer (SIS), styrene-ethylene, butylene-styrene block copolymer (SEBS) and styrene-ethylene
- SEPS propylene-styrene
- the polystyrene content is 15 to 40% by weight based on the total weight ratio to achieve the sole condition. Adjust to the following. When mixed in such a ratio, the injection molding temperature of 120 to 150 degrees and the injection molding time can be molded within 1 to 5 minutes, and the flowability during injection molding improves the adhesion to the insole window described later.
- Insole window 34 used in the present invention is a site where the sole surface of the user is in contact with the bare foot, as it is, the moisture absorbency should be good, such as sweat, and the injection molding without the adhesive with the outsole 32 described above
- the conditions under which adhesion can be achieved should be satisfied.
- a natural fiber or synthetic fiber having a thickness of 1 mm or more and having a mesh shape is used.
- the mesh diameter of the fiber is to have a size of 100 to 300 ⁇ m.
- the adhesion due to the injection molding of the sole does not sufficiently penetrate into the fiber, and the adhesiveness is decreased. If the size is more than 300 ⁇ m, the injection molding penetrates into the surface of the fiber and the touch is degraded. Will happen.
- FIG. 3 is a view showing a manufacturing process of the ultra-lightweight shoe without the adhesive process according to the present invention
- FIG. Figure shows the coupling between the bottom and the upper part.
- the insole window 34 made of fibers consisting of 100 to 300 ⁇ m mesh diameter on the injection mold.
- the sole material made of polystyrene is injected onto the mold through the injection molding machine.
- the inlet temperature of the injection machine is to be 180 to 200 °C
- the outlet temperature injected into the mold through the injection machine is to be 120 to 150 °C.
- a time of about 1 to 5 minutes is generally elapsed so that the shape of the sole 32 is completely formed and adhesion with the insole window 34 is performed.
- the injection liquid injected into the mold through the injection machine is filled in the mold because the liquid is in a liquid state, and the injection liquid in contact with the surface of the insole window 34 is It will seep between each mesh in the mesh structure.
- the liquid injection liquid is solidified as time passes while the injection liquid is injected into the mold forming the outer bottom into the shape of the mold in the state of penetrating each mesh structure, and the sole 32 is shaped as the mold. Is formed, but the components penetrated into the mesh structure of the insole window 34 is made of the adhesion between the sole 32 and the insole window 34 so that the sole 32 and insole window 34 in one form
- the bottom portion 30 may be formed.
- This process will be explained in more detail.
- sewing the edge of the portion forming the outer surface of the upper 20 in close contact with the edge of the upper surface of the insole window 34 of the bottom portion 30 Perform (a) to form the primary shoe.
- the edge portion of the upper 20 disappears from the surface contacting the floor, and only the sole 32 contacts the ground, thereby minimizing external damage of the upper 20.
- the edge forming the inner surface of the upper 20 in the manner of manufacturing the object through the conventional sewing unlike the above of the sole 32 After sewing in accordance with the bottom border, sewing in the form of turning upside down, the sole portion of the sole 32 is located on the inner surface of the upper 20 so that the upper portion of the upper 20 is in contact with the ground do. Therefore, in this case, the upper portion of the upper 20 is worn out in contact with the ground, unlike the outsole 32, the upper made of fiber is easily separated and impossible to use.
- the upper edge 20 is located on the upper surface of the insole window 32 of the bottom portion 30 so that only the sole portion 32 is in contact with the ground, so there is no damage to the upper. You lose.
- the shoe is completed through the finishing sewing of the heel portion. Therefore, it is provided with a non-slip and a grounding sole 32 having an improved grip, it is possible to manufacture an ultra-lightweight shoes without a separate bonding process.
- the present invention relates to a lightweight shoe, and more particularly, can be used in the field of a lightweight shoe and a method of manufacturing the same without a bonding process imparting adhesion and non-slip function regardless of the shape and shape of the various wearers.
