Disclosed are a shoe sole and a manufacturing method for the same are disclosed. In order to enhance flexibility and smoothness of a shoe sole, there are provided a mid sole 10 that is disposed beneath an upper layer 12 of a shoe; one or multiple protrusions 20 that protrudes in a downward direction from a lower surface 11 of the midsole; an outsole 30 that includes an upper surface 31 attached to a lower surface 11 of the midsole and includes one or multiple holes 32 that is disposed in an inner side, the protrusion passing through the outsole piece 40; and one or multiple outsole pieces 40 that are attached to beneath each protrusion. With the above configuration, it is possible to effectively absorb the impact due to prompt deformation of the sole when a user walks along an uneven, protruded ground.
Description
- The present invention relates to a shoe sole and a method for manufacturing the same, and in particular to a shoe sole and a method for manufacturing the same that make it possible to provide a sole with more flexibility and smoothness in such a way that part of a slip prevention protrusion disposed on a bottom surface of a shoe is supported by a midsole, not integrated with an outsole.
- Shoes such as sneakers, leisure shoes, mountain shoes, safety shoes, etc. are necessary items in modern human life. Such shoes are manufactured in various forms on the basis of the purpose of use. A typical shoe comprises a sole that disposed on a bottom of a shoe and supports a foot bottom, and an upper layer that covers a foot from above the sole and protects it.
- The sole consists of an outsole that directly contacts with the ground, and a midsole that is attached to the upper surface of the outsole and supports a foot bottom. The outsole is generally made from a material a little hard enough to decrease abrasion due to friction against the ground, and the midsole is generally made from a material a little smooth enough to effectively absorb impact and to enhance a wearing feeling. Some of the shoes are equipped with a slip prevention function by providing protrusions on the bottom surface of the outsole.
- Since the outsole of typical shoes is generally integrated with a hard material, flexibility and smoothness are bad.
- More specifically, when a user walks along a uneven, protruded ground like along an unpaved road or a walkway in mountain, only part of the bottom surface of the outsole comes into contact with the protruded portion, so the sole may be unbalanced or twisted. Since the outsole disposed beneath the sole is made from a hard material, the entire sole may be promptly unbalanced or twisted in reaction to the contact with the protruded ground, which results in prompt deformation. The impact due to the prompt deformation is directly transferred to the ankle of the user, so the ankle becomes fatigue fast, and the ankle may be sprained and injured, causing dangerous situation.
- Accordingly, the present invention is made so as to improve the above mentioned problems. It is an object of the present invention to provide a shoe sole and a method for manufacturing the same that make it possible to enhance flexibility and smoothness of a shoe sole.
- To achieve the above object, there is provided a shoe sole, comprising a mid sole 10 that is disposed beneath an
upper layer 12 of a shoe; one ormultiple protrusions 20 that protrudes in a downward direction from alower surface 11 of the midsole; anoutsole 30 that includes anupper surface 31 attached to alower surface 11 of the midsole and includes one ormultiple holes 32 that is disposed in an inner side, the protrusion passing through theoutsole piece 40; and one ormultiple outsole pieces 40 that are attached to beneath each protrusion. - More preferably, the midsole is smooth, and the outsole and the outsole piece are hard, and the outsole piece is attached to the soft midsole and is flexible without any help from the outsole.
- The protrusions are provided on a heel portion of a midsole where most frequently contacts with the ground or are provided on a front portion of the midsole, so it is possible to exchange when the outsole piece is worn out or damaged.
- There is further provided one or
multiple outsole protrusions 34 that protrudes in a downward direction from thebottom surface 33 of the outsole. - In addition, in order to enhance the flexibility and smoothness, the height of the protrusion is made higher than the height of the hole, so when the midsole and the outsole are attached to each other, the protrusions can protrude in a downward direction from the bottom surface of the outsole.
- In addition, when the protrusion and the outsole price are provided in multiple numbers,
different marks 21 are marked on a lower surface of each protrusion, anddifferent marks 41 are marked on an upper surface of each outsole piece for thereby differentiating the position of each protrusions. - To achieve the above objects, there is provided a method for manufacturing shoes of the present invention which comprises inserting and passing a protrusion protruding in a downward direction from a lower surface of a midsole, through a hole formed in an inner portion of the outsole; butting and attaching a lower surface of the midsole and an upper surface of the outsole; and attaching an outsole piece to beneath the protrusion that has passed through the hole.
- In the present invention, part of protrusions formed on a bottom surface of a shoe is attached to a midsole, not integrated with a hard outsole, so it can be flexible without any relation with an outsole, thus enhancing flexibility and smoothness of a shoe sole.
- When a user walks along an uneven, protruded ground, the sole can become flexible, so it is possible to absorb any impact due to prompt deformation of a sole, thus protecting ankles from being sprained and injured. The product of the present invention can reduce fatigue in the course of intense exercise or tracking or mounting climbing along with enhanced safety.

FIG. 1 , the shoe sole according to the present invention comprises amidsole 10, aprotrusion 20, anoutsole 30 and anoutsole piece 40. - The
midsole 10 is arranged beneath anupper layer 12 of a shoe and is generally made from a smoother material such as a foamed synthetic resin, etc. as compared with theoutsole 10, so it has flexibility and smoothness and a function of effectively absorbing impacts. - One or
multiple protrusions 20 protrude in a downward direction from abottom surface 11 of themidsole 10. It is preferred that theprotrusions 20 are molded in the course of the formation of themidsole 10, so theprotrusions 20 can be integrated with themidsole 10. - The
outsole 30 includes anupper surface 31 that is attached to alower surface 11 of themidsole 10 and is made from a harder synthetic resin as compared with themidsole 10. Theoutsole 30 is made from a material that has a strong abrasion prevention function because it directly contacts with the ground and that has a slip prevention property. - A
hole 32 is formed in a portion where matches with theprotrusion 20 in themidsole 10. As shown inFIG. 2 , aprotrusion 20 comes to pass through thehole 32 when themidsole 10 and theoutsole 20 are engaged each other. - The
outsole piece 40 is attached to beneath theprotrusions 20 and may be provided in one or multiple pieces. Theoutsole piece 40 is made from a material that has a strong abrasion prevention function and a slip prevention function in consideration of its direct contact with the ground. Theoutsole piece 40 may be contoured in a lattice-shaped mesh shape or a small protrusion shape on the bottom of theoutsole piece 40. - The
midsole 10 with theprotrusions 20, theoutsole 30 and theoutsole piece 40 are assembled in the following procedure. - As shown in
FIG. 1 , themidsole 10, theoutsole 30 and theoutsole piece 40 are prepared. In a state ofFIG. 2 , theprotrusions 20 protruding in a downward direction from thelower surface 11 of themidsole 10 is inserted in thehole 32 formed in the inner portion of theoutsole 30. At this time, when the exterior of theprotrusion 20 and the surrounding shape of thehole 32 are identically matched, theprotrusion 20 come to fit thehole 32 like the puzzles fit. Thelower surface 11 of the mid sole 10 and theupper surface 21 of theoutsole 30 are butted and attached. Thelower surface 11 and theupper surface 21 are attached using an adhesive or are attached in a heating and melting way. A typical attaching way of attaching the midsole and the outsole may be used; however such way is not limited thereto. - Next, the
outsole piece 40 is attached to beneath theprotrusion 20 which is exposed from its bottom after it has passed through the hole as shown inFIG. 3 . When the exterior of theoutsole piece 40 and the exterior of theprotrusion 20 are identically matched, the bottom of theprotrusion 20 is not exposed to the outside, and theoutsole piece 40 can fit theprotrusion 20, thus enhancing attaching force and support force. - When the exterior of the
protrusion 20 is atypical, and theprotrusion 20 is provided in multiple numbers, there may be a confusion in attaching theoutsole pieces 40 to eachcorresponding protrusion 20, so the protrusion with a different exterior may be attached to the outsole piece, which leads to producing defective products or retarding manufactures, thus deteriorating productivity. - On the lower surface of each
protrusion 20, for example, anidentification mark 21 such as R1 to R9 may be marked by marking a mark “R” which means a right foot shoe, or a predetermined number for eachprotrusion 20. In addition, on the upper surface of eachoutsole piece 40, for example, anidentification mark 41 which is the same as theidentification mark 21 indicated on eachprotrusion 21 or which matches withsuch mark 21 may be marked. - In such a way, even when the
outsole pieces 40 are scattered, a user can locate theprotrusion 20 with thematching identification mark 21 while confirming theidentification mark 41 of theoutsole piece 40 which is randomly selected, which consequently entails easier work. - In case that the
protrusion 20 is provided in multiple numbers, they can be installed at a heel portion of the midsole where most frequently contacts with the ground when the user walks or at a front portion of the midsole. - When a person walk, the heel portion first comes into contact with the ground after the person lifts up his one foot from the ground, and then the entre portions of the foot bottom come into contact with the ground and then the front portion comes into contact with the ground. When the person lifts up his foot from the ground, the heel portion of the foot comes to lift up from the ground, and then the front portion of the foot strongly kicks the ground, thus obtaining a forward walking force.
- In consideration of the above mentioned walking types, since the contacting force against the ground is highest at the heel portion and the front portion of the foot, so the protrusions may be sectioned into
heel portion protrusions 20 a andfront portion protrusions 20 b, for which theoutsole pieces 40 may be sectioned intoheel portion pieces 40 a andfront portion pieces 40 b. - In the present invention, the installation positions and number of the
protrusions 20 are not limited. They may be evenly formed over the entire portions of thelower surface 11 of themidsole 10 or they may be selectively formed on either the heel portions or the front portion. - According to the present invention, since the
outsole pieces 40 are attached to theprotrusions 20, when theoutsole pieces 40 are damaged or worn out, the damagedoutsole pieces 40 may be exchanged with new ones on the bass of after sale services. - In addition, when the
outsole pieces 40 are partly installed on thebottom surface 33 of theoutsole 30, there may be further provided one ormore outsole protrusions 34 which protrude in a downward direction from thebottom surface 33 of theoutsole 30 where theoutsole pieces 40 are not installed. In this case, theoutsole pieces 34 and theoutsole pieces 40 come to be evenly formed over the entire portions of thebottom surface 33 of theoutsole 30. -
FIG. 4 is a cross sectional view schematically illustrating a state that a shoe sole is disassembled, which is shown for better understanding of the present invention.FIG. 5 is a cross sectional view illustrating a state that a shoe sole is assembled, which is shown for better understanding of the present invention, wherein different from the actual shape, each component is drawn with a straight line. - As shown in
FIG. 4 , in a state that themidsole 10, theoutsole 30 and theoutsole pieces protrusion 20 of the mid sole 10 is inserted in thehole 32 of theoutsole 30, and theoutsole piece 40 is attached to beneath theprotrusion 20. The above described procedures are based on the earlier described manufacture method for a shoe sole. - In this case, as shown in
FIG. 5 , theoutsole pieces smooth protrusion 20 and are supported by the same, so eachoutsole piece hard outsole 30 and has an independent cushioning function. For example, in case that theheel portion piece 40 a comes into contact with a protruded portion of the ground, theheel portion piece 40 a absorbs and attenuates the impacts independently without any help from theoutsole 30, and on the contrary, when thefront portion piece 40 b comes into contact with a protruded portion of the ground, thefront portion piece 40 b absorbs and attenuates the impacts independently without any help from theoutsole 30, as a result of which the flexibility and smoothness of the shoe sole can be greatly enhanced. - When the height of the
protrusion 20 is lower than the height of thehole 32, the side surface of theoutsole piece 40 comes into contact with an inner wall surface of thehole 32, so there may occur interference between the materials of the outsole (more specifically, between the outsole and the outsole piece), and the flexibility of theoutsole piece 40 is restricted, which makes undesired results. - Therefore, as shown in the drawings, in order to enhance the flexibility and smoothness of the shoe sole, in the present invention, the height of the
protrusion 20 is made higher than the height of thehole 32. When the mid sole 10 and theoutsole 30 are attached to each other. When theprotrusion 20 protrudes in a downward direction from thebottom surface 33 of theoutsole 30, theoutsole piece 40 becomes completely separated from theoutsole 30, so the flexibility is not restricted. - As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
