Description

발통증완화 및 족저근막염 방지용 3D프린팅 인솔 및 이를 이용한 신발{3D printing insole and shoes using the insole}3D printing insole and shoes using the insole for foot pain relief and plantar fasciitis prevention

본 발명은 발통증완화 및 족저근막염 방지용 3D프린팅 인솔 및 이 인솔을 이용한 신발에 관한 것으로서, 보다 상세하게는 보행시 충격을 흡수하고 발아치를 지지함으로써 발통증완화 및 족저근막염 방지효과를 기대할 수 있고 통기성이 좋아 착용감도 쾌적한 새로운 구성의 3D프린팅 인솔 및 이를 이용한 신발에 관한 것이다. The present invention relates to a 3D printed insole for alleviating foot pain and preventing plantar fasciitis, and to shoes using the insole. More specifically, the present invention relates to a 3D printed insole of a new configuration that is expected to have the effect of alleviating foot pain and preventing plantar fasciitis by absorbing shock and supporting the arch of the foot when walking, and is also comfortable to wear due to good ventilation, and to shoes using the insole.

사람의 발은 보행 시 체중이 인가되면, 발바닥이 아치를 중심으로 발의 앞쪽과 뒤쪽에 지지점이 형성되며 체중을 분산시킨다. 즉, 발아치의 충격 흡수 매커니즘으로 보행 시 발생하는 일정 수준의 충격을 완화할 수 있다. 하지만, 장시간 보행시에 발에 지속적으로 많은 하중이 가해지면 발아치가 부분적으로 또는 완전히 무너지게 되며, 이 경우 발의 피로가 가중되고 통증도 발생된다. 또한, 족저근막에도 무리한 하중에 의한 스트레스가 가해져 족저근막염의 원인이 된다. When weight is applied to the foot during walking, the arch of the foot forms a support point at the front and back of the foot, distributing the weight. This shock-absorbing mechanism of the arch can mitigate a certain level of shock during walking. However, if the foot is subjected to a continuous, excessive load during prolonged walking, the arch can partially or completely collapse, resulting in increased foot fatigue and pain. Furthermore, excessive stress on the plantar fascia can lead to plantar fasciitis.

이와 같은 문제를 해결하기 위해서, 일반적으로 신발의 내부에는, 신체의 발바닥과 접하여 신체 하중을 지지하며 완충 작용으로 발을 보호하는 인솔(insole)이 구비된다. 인솔은 착용자의 발바닥과 직접 접촉하여 압력이나 충격을 분산, 흡수하는 것으로서, 착용자의 착화감에 큰 영향을 미치는 부분으로서 신발에서 상당히 중요한 요소이다. To address this issue, shoes typically feature an insole, which supports the body's weight by coming into contact with the sole of the foot and acts as a cushion to protect the foot. The insole, which comes into direct contact with the sole of the foot, distributes and absorbs pressure and shock. It significantly impacts the wearer's comfort and is a crucial element of the shoe.

그런데 종래 대부분의 인솔들은 발 바닥의 형태와 유사하게 제조되며, 발의 아치를 지지하도록 특정 부분이 돌출되어 있는데, 종래의 인솔은 대부분 폼(foam) 타입의 소재로 형성된다. 이러한 폼타입의 인솔은 장기적으로 신체의 하중을 지속 지지하기에는 충격흡수 능력이 떨어져서, 전술한 바와 같이, 발의 피로가 가중되어 발에 통증이 발생되고, 심한 경우에는 족저근막염이 발병된다. However, most conventional insoles are manufactured to resemble the shape of the sole of the foot, with specific protrusions to support the arch of the foot. Most conventional insoles are made of foam. These foam insoles lack the shock-absorbing capacity to sustain the body's weight over the long term. As mentioned above, this can lead to increased foot fatigue, foot pain, and, in severe cases, plantar fasciitis.

또한, 종래의 인솔은 대부분의 통기성이 거의 없기 때문에 특히 하절기 등에 신발을 장시간 착용하면 발에 땀이 나서 꿉꿉한 느낌을 준다. Additionally, most conventional insoles have little breathability, so wearing shoes for long periods of time, especially in the summer, can cause your feet to sweat and feel damp.

따라서, 장시간 사용에도 변형이 적고 탄성을 유지할 수 있으며, 통기성이 우수한 인솔의 개발이 요구된다. Therefore, there is a need to develop an insole that is less deformed and maintains elasticity even after long-term use, and has excellent breathability.

대한민국 공개특허 제10-2024-0056052호(2024. 04. 30.)Republic of Korea Patent Publication No. 10-2024-0056052 (April 30, 2024) 대한민국 공개특허 제10-2012-0000447호(2012. 01. 02.)Republic of Korea Publication Patent No. 10-2012-0000447 (January 2, 2012) 대한민국 공개실용신안 제252호(2007. 07. 27.)Republic of Korea Public Utility Model No. 252 (July 27, 2007)

본 발명은 상기와 같은 문제점에 착안하여 제안된 것으로서, 내부에서 삼차원적으로 연결되는 통기공을 가지는 삼차원 망상구조를 가지도록 3D 프린팅으로 제조되어 보행시 충격을 흡수하고 발아치를 지지함으로써 발통증완화 및 족저근막염 방지효과를 기대할 수 있고 통기성이 좋아 착용감도 쾌적한 새로운 구성의 3D프린팅 인솔 및 이를 이용한 신발을 제공하는 것이다.The present invention has been proposed in consideration of the above-mentioned problems, and provides a new configuration of a 3D printed insole and shoes using the same, which are manufactured by 3D printing to have a three-dimensional network structure with three-dimensionally connected internal air holes, thereby absorbing shock when walking and supporting the arch of the foot, thereby alleviating foot pain and preventing plantar fasciitis, and which are also breathable and comfortable to wear.

본 발명의 특징에 따르면, 착용자의 발아치가 지지되는 아치지지부(13)가 돌출형성되어 착용자의 발이 안착되는 인솔본체(12)와, 상기 인솔본체(12)의 둘레면의 상호 대향되는 위치에서 인솔본체(12)의 상면보다 낮은 상면을 가지도록 외측으로 돌출된 한 쌍의 결합돌부(14)를 포함하며, 상기 인솔본체(12)와 결합돌부(14)는 삼차원망상구조를 가지도록 3D프린팅되어, 인솔본체(12)와 결합돌부(14)에는 내부에서 삼차원적으로 연결되는 통기공(11)이 형성된 것을 특징으로 하는 발통증완화 및 족저근막염 방지용 3D프린팅 인솔(10)이 제공된다.According to a feature of the present invention, a 3D printed insole (10) for relieving foot pain and preventing plantar fasciitis is provided, which comprises an insole body (12) on which an arch support part (13) for supporting the arch of the wearer's foot is protruded and on which the wearer's foot rests, and a pair of connecting protrusions (14) protruding outward at mutually opposing positions on the circumferential surface of the insole body (12) so as to have an upper surface lower than the upper surface of the insole body (12), wherein the insole body (12) and the connecting protrusions (14) are 3D printed to have a three-dimensional network structure, and ventilation holes (11) that are three-dimensionally connected internally are formed in the insole body (12) and the connecting protrusions (14).

본 발명의 다른 특징에 따르면, 상기 아치지지부(13)는 상기 인솔본체(12)의 다른 부분에 비해 상대적으로 높은 밀도를 가진다.According to another feature of the present invention, the arch support part (13) has a relatively high density compared to other parts of the insole body (12).

본 발명의 또 다른 특징에 따르면, 상기 결합돌부(14)는 상기 인솔본체(12)의 길이방향 양단에서 돌출형성된다.According to another feature of the present invention, the connecting protrusion (14) is formed to protrude from both longitudinal ends of the insole body (12).

본 발명의 또 다른 특징에 따르면, 상기 인솔(10); 및 상기 인솔본체(12)가 상면이 노출되도록 수용되는 인솔수용부(22)와, 상기 인솔수용부(22) 둘레부에서 외측으로 개방되도록 수평방향으로 형성되어, 상기 결합돌부(14)가 끼워지는 수평결합공(24)이 형성된 아웃솔(20);을 포함하여, 상기 인솔(10)이 상기 아웃솔(20)에 결합되면, 상기 결합돌부(14)의 선단이 상기 수평통기공(24)을 통해 외부로 노출되어, 상기 결합돌부(14)를 통해 인솔본체(12) 내부로 통기가 이루어지는 것을 특징으로 하는 발통증완화 및 족저근막염 방지용 신발이 제공된다. According to another feature of the present invention, a shoe for relieving foot pain and preventing plantar fasciitis is provided, comprising: an insole (10); and an insole receiving portion (22) in which the insole body (12) is received so that its upper surface is exposed; and an outsole (20) having a horizontal connecting hole (24) formed so as to be opened outwardly from a periphery of the insole receiving portion (22), into which the connecting protrusion (14) is fitted; When the insole (10) is connected to the outsole (20), the tip of the connecting protrusion (14) is exposed to the outside through the horizontal ventilation hole (24), so that ventilation is provided into the insole body (12) through the connecting protrusion (14).

이상과 같은 구성을 가지는 본 발명에 의한 인솔(10)은 삼차원망상구조를 가지도록 3D프린팅으로 제조되어 내부에서 삼차원적으로 연결되는 통기공(11)들이 형성되므로 통기성과 완충성을 가진다. The insole (10) according to the present invention having the above configuration is manufactured by 3D printing to have a three-dimensional network structure, and thus has ventilation holes (11) that are three-dimensionally connected inside, thereby providing breathability and cushioning.

따라서 본 발명에 의한 인솔(10)이 적용된 신발을 착용하면 보행시 충격을 흡수하므로 착용감이 좋고 장시간 착용하더라고 발통증이 예방 및 완화되고, 특히, 아치지지부(13)가 다른 부분에 비해 높은 밀도를 가지도록 형성되므로 신발을 장시간 착용하더라도 발아치가 무너지지 않고 지지되므로 발의 균형이 유지되며, 따라서 족저근막에 가해지는 압력이 감소되어 통증이 완화되고, 족저근막염의 개선 및 족저근막염의 발생을 예방하는 효과도 얻을 수 있다. Therefore, when wearing a shoe to which an insole (10) according to the present invention is applied, shock is absorbed when walking, so it is comfortable to wear, and foot pain is prevented and alleviated even when worn for a long time, and in particular, since the arch support part (13) is formed to have a higher density than other parts, the arch of the foot is supported without collapsing even when the shoe is worn for a long time, so that the balance of the foot is maintained, and therefore, the pressure applied to the plantar fascia is reduced, pain is alleviated, and the effect of improving plantar fasciitis and preventing the occurrence of plantar fasciitis can also be obtained.

또한, 인솔(10)의 통기성으로 인해 신발을 장시간 착용하여도 발에 땀이 차지 않아 쾌적한 착용감이 유지되며, 본 발명에 의한 인솔(10)은 아웃솔(20)에 끼움결합되므로 신발 제조시 접착제의 사용도 줄일 수 있으며, 신발 외관도 깔끔한 장점도 가진다.In addition, due to the breathability of the insole (10), the feet do not sweat even when the shoes are worn for a long time, maintaining a comfortable wearing feeling. In addition, since the insole (10) according to the present invention is fitted into the outsole (20), the use of adhesive can be reduced during shoe manufacturing, and the shoe also has the advantage of a neat appearance.

도 1 내지 도 5는 본 발명의 바람직한 실시예의 도면들이고, 본 발명에 의한 인솔(10)은 도시된 바와 같이, 인솔본체(12)와, 인솔본체(12)의 둘레면에서 상호 대향되도록 돌출된 한 쌍의 결합돌부(14)를 포함한다. FIGS. 1 to 5 are drawings of preferred embodiments of the present invention, and as shown, the insole (10) according to the present invention includes an insole body (12) and a pair of connecting protrusions (14) that protrude so as to face each other on the circumference of the insole body (12).

상기 인솔본체(12)는 착용자의 발이 안착되는 부분으로서, 착용자의 발아치가 지지되는 아치지지부(13)가 형성되는 등 인솔본체(12)의 상면은 발바닥에 대응되는 입체적인 형태를 가진다. The above insole body (12) is the part where the wearer's foot rests, and the upper surface of the insole body (12) has a three-dimensional shape corresponding to the sole of the foot, such as the formation of an arch support part (13) that supports the wearer's arch.

그리고 상기 결합돌부(14)는 인솔본체(12)의 둘레면에서 상호 대항되도록 한 쌍이 구비되는데, 후술하는 바와 같이, 아웃솔(20)에 형성된 수평결합공(24)에 끼워질 수 있도록 상면이 인솔본체(12)의 상면보다 낮게 형성된다. 본 실시예에서는 결합돌부(14)가 인솔본체(12)의 길이방향 양단, 즉, 발가락부위와 뒤꿈치부위에서 전후로 돌출된 것으로 예시되었으나, 결합돌부(14)의 위치는 이에 국한되지 않고, 인솔본체(12)의 좌우 양측에서 돌출될 수도 있다.And the above-mentioned connecting protrusions (14) are provided in pairs so as to be opposed to each other on the circumference of the insole body (12), and as described later, the upper surface is formed lower than the upper surface of the insole body (12) so that they can be fitted into the horizontal connecting hole (24) formed in the outsole (20). In the present embodiment, the connecting protrusions (14) are exemplified as protruding forward and backward from both longitudinal ends of the insole body (12), i.e., the toe area and the heel area, but the position of the connecting protrusions (14) is not limited thereto, and may protrude from both left and right sides of the insole body (12).

이러한 결합돌부(14)는 후술하는 바와 같이, 인솔본체(12) 내부로 통기가 원활하게 이루어지도록 하는 통기로로서의 기능을 하면서 아울러, 인솔(10)이 아웃솔(20)과 결합되도록 하는 결합수단으로서의 기능을 한다.As described later, this joining protrusion (14) functions as a ventilation passage to ensure smooth ventilation inside the insole body (12), and also functions as a joining means to join the insole (10) to the outsole (20).

이러한 인솔(10)은 상기 인솔본체(12)와 결합돌부(14)가 일체를 이루도록 형성되는데, 인솔(10)의 골격을 이루는 지지살들이 전후좌우 및 상하로 연결되어 오픈셀형태를 이루는 삼차원 망상구조를 가지도록 3D프린터로 프린팅된다. 따라서 인솔(10) 표면, 즉, 인솔본체(12)와 결합돌부(14)의 표면에는 내부에서 삼차원적으로 연결되는 통기공(11)들이 형성되며, 이에 따라 인솔본체(12)와 결합돌부(14)는 원활한 통기성을 가진다. This insole (10) is formed so that the insole body (12) and the connecting protrusion (14) are integrally formed, and the supporting ribs forming the skeleton of the insole (10) are connected in the front, back, left, right, up and down directions to form a three-dimensional network structure that is printed with a 3D printer to form an open cell shape. Accordingly, on the surface of the insole (10), that is, on the surface of the insole body (12) and the connecting protrusion (14), ventilation holes (11) that are three-dimensionally connected from the inside are formed, and accordingly, the insole body (12) and the connecting protrusion (14) have smooth ventilation.

또한, 인솔(10)은 통기성과 더불어 완충성도 가지도록 열가소성 엘라스토머(TPE, Thermoplatsic Elastomer)로 3D프린팅되는데, 바람직하게는 TPU(Thermoplastic Polyurethane), TPA(Thermoplastic Polyamide elastomer)가 사용되며, 내구성과 착화감 등을 고려할 때 경도 85∼95IRHD, 인장강도 8∼15MPa, 인장탄성률 45MPa 이상, 최대변형률 95% 이상, 인열강도 40∼60 kN/m, 내마모성 190이상인 것을 사용하는 것이 바람직하다. In addition, the insole (10) is 3D printed with thermoplastic elastomer (TPE) to have both breathability and cushioning, preferably TPU (Thermoplastic Polyurethane) or TPA (Thermoplastic Polyamide elastomer) is used, and considering durability and fit, it is preferable to use one having a hardness of 85 to 95 IRHD, a tensile strength of 8 to 15 MPa, a tensile modulus of elasticity of 45 MPa or more, a maximum strain of 95% or more, a tear strength of 40 to 60 kN/m, and an abrasion resistance of 190 or more.

이러한 인솔(10) 특히, 상기 인솔본체(12)는 보행시 가해지는 하중을 지지하면서 충격을 흡수할 수 있는 밀도를 가지도록 전술한 소재로 3D프린팅되는데, 바람직하게는 인솔본체(12)의 아치지지부(13)는 다른 부분보다 상대적으로 높은 밀도를 가지도록 3D 프린팅된다. 따라서 아치지지부(13)에 의해 착용자의 발아치가 무너지지 않고 안정적으로 지지된다. These insoles (10), particularly the insole body (12), are 3D printed with the aforementioned material to have a density capable of absorbing shock while supporting the load applied during walking. Preferably, the arch support portion (13) of the insole body (12) is 3D printed to have a relatively higher density than other portions. Therefore, the wearer's arch is stably supported without collapsing by the arch support portion (13).

이와 같은 구성을 가지는 인솔(10)은 상기 결합돌부(14)를 이용하여 신발의 아웃솔(20)에 끼움결합되는데, 상기 인솔(10)이 적용되는 아웃솔(20)에는 도 3 내지 5에 도시된 바와 같이, 상향으로 개방되어 인솔본체(12)가 수용되는 인솔수용부(22)와, 인솔수용부(22)의 둘레부에서 외측으로 개방되도록 수평방향으로 형성되어 상기 결합돌부(14)가 끼워지는 수평결합공(24)이 형성된다.The insole (10) having such a configuration is fitted into the outsole (20) of the shoe using the above-mentioned connecting protrusion (14). As shown in FIGS. 3 to 5, the outsole (20) to which the insole (10) is applied has an insole receiving portion (22) that is opened upward to receive the insole body (12), and a horizontal connecting hole (24) that is formed horizontally so as to be opened outward from the circumference of the insole receiving portion (22) and into which the connecting protrusion (14) is fitted.

따라서 상기 인솔(10)은 인솔본체(12)가 인솔수용부(22)에 수용되고 결합돌부(14)는 수평결합공(24)에 삽입되도록 아웃솔(20)에 끼움결합되는데, 인솔본체(12)가 인솔수용부(22)에 억지끼움되고 아울러 결합돌부(14)가 수평결합공(24)에 삽입되어 인솔(10)이 아웃솔(20)에 결합된 상태가 유지된다.Accordingly, the above insole (10) is fitted into the outsole (20) so that the insole body (12) is accommodated in the insole receiving portion (22) and the connecting protrusion (14) is inserted into the horizontal connecting hole (24). The insole body (12) is forcibly fitted into the insole receiving portion (22) and the connecting protrusion (14) is inserted into the horizontal connecting hole (24), so that the insole (10) is maintained in a state of being coupled to the outsole (20).

이와 같이 인솔(10)이 아웃솔(20)에 결합되면 인솔본체(12)의 상면은 아웃솔(20) 상부로 노출되고, 결합돌부(14)의 선단은 수평결합공(24)을 통해 외부로 노출된다. 따라서 인솔(10) 내부로 통기가 원활하게 이루어지는데, 특히, 결합돌부(14)의 선단이 수평결합공(24)을 통해 외부로 노출되기 때문에, 착용자가 신발을 착용한 상태에서 인솔본체(12)의 상면이 착용자의 발에 커버되어 인솔본체(12) 상면의 통기공이 막히더라도 결합돌부(14)의 선단을 통해 인솔본체(12)로 통기가 이루어진다. 따라서 본 발명에 의한 인솔(10)이 적용된 신발은 도시된 바와 같이, 어퍼(26)가 발가락과 발등을 감싸는 타입으로 이루어지더라도 발에 땀이 차지 않는다. When the insole (10) is connected to the outsole (20) in this way, the upper surface of the insole body (12) is exposed to the upper part of the outsole (20), and the tip of the connecting protrusion (14) is exposed to the outside through the horizontal connecting hole (24). Therefore, ventilation is smoothly performed inside the insole (10). In particular, since the tip of the connecting protrusion (14) is exposed to the outside through the horizontal connecting hole (24), even if the upper surface of the insole body (12) is covered by the wearer's foot while the wearer is wearing the shoe and the ventilation hole of the upper surface of the insole body (12) is blocked, ventilation is performed into the insole body (12) through the tip of the connecting protrusion (14). Therefore, a shoe to which the insole (10) according to the present invention is applied does not cause sweating in the feet even if the upper (26) is formed as a type that wraps around the toes and the instep as shown in the drawing.

통상적으로 신발 착용시 발가락부위에 땀이 많이 나는데, 특히, 본 실시예와 같이, 결합돌부(14)가 인솔본체(2)의 전후단부, 즉, 발가락부와 뒤꿈치부에서 돌출되면 발가락부위에 좀 더 원활한 통기가 이루어지므로 발가락부위에 땀이 나는 것이 효과적으로 방지된다. Normally, when wearing shoes, the toes sweat a lot, but in particular, as in this embodiment, when the connecting protrusion (14) protrudes from the front and rear ends of the insole body (2), that is, the toes and the heel, more smooth ventilation is achieved in the toes, effectively preventing sweating in the toes.

이상과 같은 구성을 가지는 본 발명에 의한 인솔(10)은 삼차원망상구조를 가지도록 3D프린팅으로 제조되어 내부에서 삼차원적으로 연결되는 통기공(11)들이 형성되므로 통기성과 완충성을 가진다. 따라서 본 발명에 의한 인솔(10)이 적용된 신발을 착용하면 보행시 충격을 흡수하므로 착용감이 좋고 장시간 착용하더라고 발이 불편하지 않고 편안하므로 발통증이 유발되지 않거나 다른 신발을 착용한 경우에 비해 통증이 완화된다. 특히, 발아치를 지지하는 아치지지부(13)가 다른 부분에 비해 높은 밀도를 가지도록 형성되어, 발아치가 지지되므로 신발을 장시간 착용하더라도 발아치가 무너지지 않아 발의 균형이 유지되며, 따라서 족저근막염의 개선 및 족저근막염의 발생을 예방하는 효과도 얻을 수 있다. The insole (10) according to the present invention having the above configuration is manufactured by 3D printing to have a three-dimensional network structure, and air holes (11) are formed that are three-dimensionally connected internally, so that it has breathability and cushioning. Therefore, when a shoe with the insole (10) according to the present invention applied is worn, the shock is absorbed when walking, so it is comfortable to wear, and even if worn for a long time, the feet are comfortable without discomfort, so that foot pain is not induced or the pain is relieved compared to when wearing other shoes. In particular, the arch support part (13) that supports the arch of the foot is formed to have a higher density than other parts, so that the arch of the foot is supported, so that even if the shoe is worn for a long time, the arch of the foot does not collapse, so that the balance of the foot is maintained, and therefore, the effect of improving plantar fasciitis and preventing the occurrence of plantar fasciitis can also be obtained.

또한, 인솔(10)의 통기성으로 인해 신발을 장시간 착용하여도 발에 땀이 차지 않으므로 쾌적한 착용감이 유지된다. Additionally, due to the breathability of the insole (10), the feet do not become sweaty even when the shoes are worn for a long time, so a comfortable feeling of wearing is maintained.

뿐만 아니라 본 발명에 의한 인솔(10)은 아웃솔(20)에 끼움결합되므로 본 발명에 의한 인솔(10)이 적용된 신발은 접착제를 사용하여 인솔(10)을 아웃솔(20)에 결합시키기 않아도 되므로 신발 제조시 접착제의 사용을 줄일 수 있고, 인솔(10)을 접착제로 부착시킨 신발에 비해 신발 외관도 깔끔하다 In addition, since the insole (10) according to the present invention is fitted into the outsole (20), the shoes to which the insole (10) according to the present invention is applied do not need to use an adhesive to attach the insole (10) to the outsole (20), so the use of adhesive can be reduced during shoe manufacturing, and the appearance of the shoes is also neat compared to shoes to which the insole (10) is attached with an adhesive.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것은 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 발명이 속하는 기술분야에서의 통상의 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiments and the attached drawings, and it will be apparent to a person having ordinary skill in the art to which the present invention pertains that various substitutions, modifications, and changes are possible within a scope that does not depart from the technical spirit of the present invention.
