Abstract
Description
[Technical field]
[0001] This invention relates to a walking correction shoe that can change the center of gravity at the time of landing and correctly guide the deviated step direction to the appropriate direction, thereby correcting walking posture. [Background technology]
[0002] Casual shoes are mainly composed of three layers, including a vamp structure, an intermediate inner layer structure, and a sole structure. The vamp structure is made of a highly breathable vamp material that secures the user's foot and protects the instep. The intermediate inner layer structure further stabilizes the foot to reduce abrasions caused by twisting or slipping. The sole structure is made of a sole material that has high cushioning and anti-slip properties. When actually wearing and walking, the intermediate inner layer structure and the sole structure of the shoe work together to provide elasticity, cushioning, and vibration reduction effects, allowing the user to comfortably carry out daily activities and light exercise such as walking and running. Summary of the Invention [Problem to be solved by the invention]
[0003] However, although conventional shoes provide comfort to most people, they are not suitable for people with congenital skeletal abnormalities, people with long-standing bad posture habits, and certain groups of people who walk with their legs wide apart or knock-kneed due to genetic factors, etc. In the long term, incorrect walking posture and manner of walking can easily cause pelvic distortion, spinal diseases, back pain, etc., and are problems that need to be solved.
[0004] The present invention has been made in consideration of the above problems, and aims to provide walking correction shoes that change the center of gravity and angle of landing when walking, correctly guiding deviated steps in the appropriate direction and correcting poor walking posture. [Means for solving the problem]
[0005] In order to achieve the above object, a walking correction shoe according to one embodiment of the present invention mainly comprises a shoe body and a sole layer. The sole layer is formed by laminating an insole and a large bottom, and the large bottom is formed by connecting a front sheet, a middle sheet, and a rear sheet to each other. The front sheet and the rear sheet are respectively curved upward based on the forward tilt angle and the backward tilt angle, and the backward tilt angle is larger than the forward tilt angle, so that the large bottom has an arc-shaped curved structure with a high back and a low front. In addition, the point where the front sheet and the middle sheet are connected to each other is the landing point that defines the landing surface facing backward, so that when the foot is put into the shoe body and the person walks forward, the center of gravity, angle, and landing area of the sole of the landing point change so as to correctly guide the deviated step direction forward, and the center of gravity of the body is instantly returned to the correct position and balance is maintained, thereby achieving the purpose of improving poor walking posture.

[0008] The following describes in detail the embodiments of the present invention, but the present invention is not limited to these, and various modifications are possible within the scope of the description, and embodiments obtained by appropriately combining the technical means disclosed in the different embodiments are also included in the technical scope of the present invention.
[0009] As shown in FIG. 1, the walking correction shoe according to the present invention is composed of a shoe body 10 and a sole layer 11. The shoe body 10 and the sole layer 11 are connected to each other, and the shoe body 10 is a cover body having high breathability and protection. If necessary, the material may be, for example, one of leather, suede, cloth, synthetic leather, or a mixture of them. The sole layer 11 is composed of an insole part 111 and a large bottom part 112, and the insole part 111 has an upward curvature at the front edge part of the surface, and the main body is made of a thick material such as polyurethane (PU), ethylene vinyl acetate copolymer (EVA), or PHYLON, but the present invention is not limited thereto. Preferably, one or a combination of carbon fiber, air, and vibration absorbing gel may be further mixed in to enhance the lightness and solidity of the entire insole portion 111.
[0010] The large bottom 112 is a thin sheet-like body whose hardness is harder than that of other materials of the insole 111, and can support the weight of the human body. The material may be one of rubber, leather, natural rubber, synthetic rubber, or a combination thereof, but the present invention is not limited thereto. The large bottom 112 has sufficient anti-slip effect, wear resistance, solidity, and support. The large bottom 112 is formed by connecting the front sheet 1121, the middle sheet 1122, and the rear sheet 1123 to each other. The front sheet 1121 is the front end of the large bottom 112, one end of which is connected to the middle sheet 1122, and defines a division with the middle sheet 1122 at the landing point A. That is, the landing point A is located between the front sheet 1121 and the middle sheet 1122. The other end of the middle sheet 1122 is connected to the rear sheet 1123, so that the rear sheet 1123 is formed as the rear end of the large bottom 112. The front sheet 1121 and the rear sheet 1123 are curved upward at the front and rear ends of the large bottom 112, respectively, to form an arc-shaped curved structure. To be more specific, when wearing the walking correction shoe 1 according to the present invention and walking forward, in a normal state (flat ground), the middle sheet 1122 of the large bottom 112 contacts the ground when landing. When walking forward, the position of the landing point A lands on the ground first, and the center of gravity of the landing during walking is adjusted, so that the wearer feels a sense of division throughout the entire walking process, and when walking forward, the sole of the foot is placed on the ground along the front sheet 1121.
[0011] As shown in Fig. 2, in this embodiment, the front edge portions of the shoe body 10 are connected to each other to form the toe part 101, an opening for inserting the foot is opened at the top of the shoe body 10, and a space 102 for accommodating the foot is formed inside the opening. The coverage area of the shoe body 10 is determined by the size of the covering space of the space 102 for accommodating the foot. In addition, the outer edge of the bottom surface of the shoe body 10 is connected to correspond to the outer edge of the upper surface of the insole part 111. When the connection is completed, the bottom surface other than the outer edge of the shoe body 10 becomes an upward space, that is, the space 102 for accommodating the foot, and at the same time, the toe part 101 corresponds to the front edge portion of the insole part 111 and exhibits an upward curvature. The bottom surface of the insole part 111 is connected to the top surface of the large bottom part 112 so as to correspond to it, and the part where the center part of the bottom surface of the insole part 111 extends forward is a small wave-like structure formed with spaced projections and depressions. The outer shape of the insole part 111 conforms to the wave-like structure, so that both sides of the insole part 111 have a smooth wave pattern, but it may be designed as other different types of patterns or patterns, improving the texture and aesthetics of the overall appearance. The large bottom part 112 may be formed into a wave-like structure with spaced projections and depressions opposite to the insole part 111. Returning to FIG. 1, after being connected, the insole part 111 and the large bottom part 112 are further fixed tightly by the intersecting projections and depressions being attached to each other.
[0012] As shown in Fig. 3, the surface of the insole part 111 has a contact surface 1111 extending from the back to the front to the position of the toe part 101 (not shown), and the front edge part has the same upward curvature as the insole part 111, and the contact surface 1111 is a non-adhesive surface. More specifically, the contact surface 1111 is a functional surface, for example, it can be in direct contact and can be a position where the sole of the human body is placed, or it can be expanded in application. For example, a gel, foam mat, or air cushion can be inserted into the upward curvature part of the front end of the contact surface 1111 to reduce the situation where calluses are formed due to friction between the toes or deformation due to pressure when walking for a long time.
[0013] As shown in FIG. 4, the front sheet 1121 is curved upward based on a forward tilt angle θ1, which is an included angle between the front sheet 1121 and the ground / horizontal plane (reference object), and a first height H1 is formed by a vertical height from the top end of the front sheet 1121 to the height of the horizontal plane. Preferably, the forward tilt angle θ1 is in the range of 22 to 28 degrees, but the present invention is not limited thereto. The rear sheet 1123 is also curved upward based on a backward tilt angle θ2, and a second height H2 is formed by a vertical height from the top end of the rear sheet 1123 to the height of the horizontal plane. The backward tilt angle θ2 is an included angle between the rear sheet 1123 and the horizontal plane, which corresponds to the front sheet 1121 or is larger than the forward tilt angle θ1, and preferably, the backward tilt angle θ2 is 35 degrees or more, but the present invention is not limited thereto. In addition, as the angle increases, the inclination of the object relative to the horizontal plane also increases, and the distance of the apex / top of the object relative to the horizontal plane also increases. Therefore, in this invention, the rearward tilt angle θ2 is made larger than the forward tilt angle θ1, so that the second height H2 of the rear seat 1123 is made higher than the first height H1 of the front seat 1121. In this way, as shown in the figure, the large bottom 112 has a shape that is high at the back and low at the front, which has the effect of returning the center of gravity of the body to the correct position and maintaining balance when walking.
[0014] As shown in Fig. 5, the foot 2 is inserted into the space 102 for accommodating the foot through the opening of the shoe body 10. The sole 21 is placed on the contact surface 1111, and the toe 22 is placed at the front end of the contact surface 1111 and abuts against the toe cap 101, so that the toe 22 conforms to the upward curvature of the contact surface 1111 and is curved upward. The heel 23 abuts at a position close to the rear of the center of the shoe body 10, and overall, the maximum comfort is achieved when the foot 2 is inserted into the walking correction shoe 1 according to the present invention.
[0015] As shown in FIG. 6, the walking correction shoe 1 according to the present invention has a toe lifted up in the first movement of walking forward, as shown in the figure, and in the second movement after the movement, the middle sheet 1122 contacts the ground as described above. When walking forward, when the position of the landing point A lands and contacts the ground, the center of gravity of the landing changes. Due to the structural function of the landing point A, the front sheet 1121 and the middle sheet 1122 of the large bottom 112 are clearly divided. That is, the part facing forward of the landing point A is the front sheet 1121 that is not the landing range. More specifically, the landing point A defines the extended middle sheet 1122 backward as the range of the landing surface B, and the landing surface B refers to the part facing downward from the bottom surface of the middle sheet 1122, and this part is continuously extended backward to the range where the rear sheet 1123 is located. In normal conditions (flat ground), the landing surface B is in contact with the ground, so the landing surface B indicates the area that actually touches the ground. Therefore, when walking forward, the area where the sole touches the ground changes, and at the same time, the change in landing point A creates a drop, so that you can feel a sense of separation when walking.
[0016] As shown in FIG. 7, the direction of action D1 indicates the biased force direction when a person with bad walking manner walks forward (this figure illustrates the force direction of the turn-toe force). The corrected direction D2 is the correct step direction that is correctly guided by wearing the present invention, and the corrected direction D2 is preferably forward. Therefore, before being correctly guided, the direction of the turn-toe action D1 is the direction in which the force is applied to turn the foot inward, so when viewed from a bird's-eye view, the step position of the shoe body is distorted toward the right (this figure illustrates the step position of the left foot and left shoe). By correctly guiding, the step direction is guided from the right direction to the forward direction. In the process of correctly guiding, the landing point A is set as the landing reference, and when the landing point is viewed from a bird's-eye view, its range is the parallel width of the sole (shown in a dashed frame), and is the range that is first contacted with the ground when the foot lands. In addition, when the foot lands, the front sheet 1121 at the front end of the sole layer 11 has an arc-shaped curved structure, so that the structure transition occurs when walking forward. That is, originally, the foot first steps on the middle sheet 1122, passes through the landing point A, and when the large bottom 112 is stepped on forward, a breaking point action occurs, and the force of the foot is transferred to the front sheet 1121. As a result, when the angle and center of gravity change, the acting force corresponding to the original action direction D1 is applied according to the correction direction D2 due to the inertia when the force is applied, and the step position of the walking correction shoe 1 is correctly guided forward.
[0017] As shown in Fig. 8, in this invention, an arch insole 3 is installed in the space 102 that accommodates the foot, which is laid on the surface of the contact surface 1111 of the insole part 111 and has a moderate hardness. A protrusion 31 protrudes upward from the center of the arch insole 3, and when a patient with cavus pes wears it, the protrusion 31 hits the patient's too high arch part, relieving the patient's pain, improving the comfort and feeling of wearing, and further enhancing the correction effect.
[0018] To sum up, the walking correction shoe of the present invention has an arc-shaped curved structure with a forward inclination angle at the front end of the large sole, so that when the foot lands and steps forward, a sense of separation occurs, and the step is guided to the correct position due to the function of the structure, so that the bad posture of the pedestrian is improved. As described above, when the present invention is implemented, the center of gravity and angle of the landing when walking are changed, and the deviated step is correctly guided in the appropriate direction, and this characteristic reliably achieves the purpose of the walking correction shoe, which is to correct the bad walking posture.
[0019] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means devised in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
