Description

  The present invention relates to an insole structure, and more particularly to an insole structure that can be freely taken in and out of a shoe and that can correct the posture of a foot.

  A person's foot has 26 bones, and when a person stands, the root of the first metatarsal bone, the hip of the fifth metatarsal bone, and the ribs are used as support points. It is done. The first metatarsal bone and the fifth metatarsal bone are not in a horizontal state, and the first metatarsal bone is lower than the fifth metatarsal bone, and an arch is formed by three points where the heights are distributed to support the body. A constant arch is maintained on the human foot, and since it has a cushioning property when walking, it is hard to get tired. Shoes are the basic footwear that protects feet when walking or running, and human feet support one to two times their weight, preventing injury to human bones, joints or muscles. Insole that protects the foot was necessary in the shoe.

  All shoes currently on the market include insoles (linings). The insole is roughly divided into two types, the first type can be taken out by itself, the second type is fixed to the shoe sole and cannot be taken out, and their main functions are appropriate and flexible It is to improve comfort by sex. By the way, the removable insole 2 that can be exchanged or attached to shoes that has been distributed in the market is a flat insole (see FIG. 6), and the bottom layer material has a thickness of about A foam material of 3-7 mm is used, and a surface layer is bonded to the upper surface of the bottom layer. This surface layer may consist of reticulated breathable fibers, general fabric, artificial leather or leather. The insole 2 described above is mainly used as a soft lining in a shoe or a lining for a spacer that is too large between a shoe body and a foot. Therefore, such an insole 2 softens the impact and distributes the pressure at the above-described three support points of the foot portion, but does not support the lateral foot arch of the front foot portion of the human foot portion. For this reason, when a person stands or walks, the pressure and weight of the forefoot's lateral foot arch applied from the body cannot be supported by the flat insole or the impact can be reduced. It was necessary to support by elasticity. In other words, the conventional insole 2 cannot support the lateral foot arch of the forefoot part and cannot reduce the pressure of the forefoot part when standing or walking. Such an insole 2 has a low selling price and a low manufacturing cost, but is unfavorable for the foot in terms of ergonomics and cannot improve the functionality of exercise or walking.

  The insole structure can reduce the vibration by thickening the high pressure part of the pressure plate at the sole, reducing the force applied to the high pressure region, but it can transmit the pressure to the arch or receive it on other non-tread parts. However, since the foot pressure plate cannot react immediately, the foot and fascia may be damaged when used for a long time.

  An object of the present invention is to provide an insole structure that can be freely taken in and out of a shoe and that can correct a posture of a foot.

  In order to solve the above problems, according to a first embodiment of the present invention, an insole structure including an insole body, the insole body having an insole having an appropriate thickness and flexibility, The insole body has a forefoot portion, an arch region, and a heel region, and the forefoot portion is provided with a tread surface portion that is recessed so as to correspond to the thumb ball of the foot portion and to which the thumb ball contacts. The outer support portion is connected to the outer side of the tread portion, the side recess is connected to the rear side of the outer support portion, and the thickness of the outer support portion is larger than the thickness of the tread portion, Provided is an insole structure in which the side recess and the tread surface portion are equal in depth, and the thickness of the outer support portion is smaller than the thickness of the insole body.

  It is preferable that the outer support portion is smoothly connected to the tread surface portion to form an inclined surface.

  It is preferable that the forefoot part is provided with a thumb accommodating part corresponding to the thumb and connected to the tread surface part, and the thumb accommodating part is recessed in a shape corresponding to the thumb.

The insole structure of the present invention has the following effects (1) to (4) as compared with the conventional structure.
(1) The front tread is tilted inward slightly and the insole is corrected inward by the indented tread surface so that the stress when walking on the ground is smoothly transmitted, making it easier and easier and improving comfort. To do.
(2) Since the inertia of the kinetic energy generated when walking increases and the resistance decreases, the feeling of fatigue can be greatly reduced.
(3) Due to the indented tread surface, the forefoot sole is slightly tilted inward, so that the sole can be corrected inwardly, reducing pressure on the lumbar spine and hurting when standing for a long time Can be prevented.
(4) When the insole body is inserted into the shoe, the sole can be corrected, and the insole body becomes thinner and lighter and the volume is reduced.

  In order to more fully and clearly disclose the technical means of the present invention and the effects achievable thereby, the present invention is described in detail below in conjunction with the accompanying drawings and reference numerals disclosed.

  First, reference will be made to FIGS. FIG. 1 is a perspective view showing an insole body having an insole structure according to an embodiment of the present invention. FIG. 2 is a plan view showing an insole body having an insole structure according to an embodiment of the present invention. FIG. 3 is an explanatory diagram of a state in which a foot is combined with an insole body having an insole structure according to an embodiment of the present invention. FIG. 4 is a cross-sectional view taken along line aa in FIG. As shown in FIGS. 1 to 4, the insole structure according to an embodiment of the present invention is composed of at least an insole body 1.

  The insole body 1 has an insole having an appropriate thickness and flexibility. The insole body 1 includes a forefoot portion 11, an arch region 12 and a heel region 13. The front foot portion 11 is provided with a tread surface portion 111 that is recessed so as to correspond to the thumb ball T of the foot portion and to which the thumb ball T abuts. An outer support portion 112 is connected to the outer side of the tread portion 111. A side recess 113 is connected to the rear side of the outer support portion 112. The thickness of the outer support portion 112 is larger than the thickness of the tread portion 111. The depths of the side recess 113 and the tread portion 111 are equal, and the thickness of the outer support portion 112 is smaller than the thickness of the insole body 1.

  The outer support portion 112 is smoothly connected to the tread surface portion 111 to form an inclined surface S. The front foot portion 11 of the insole body 1 is provided with a thumb accommodating portion 114 corresponding to the thumb and connected to the tread portion 111. The thumb accommodating portion 114 is recessed with a shape corresponding to the thumb.

  Please refer to FIG. As shown in FIG. 1 to FIG. 5, first, a stress guide path due to the movement of the foot when a person walks will be described so that the function of the insole structure according to an embodiment of the present invention can be easily understood ( Indicated by an arrow). As shown in FIG. 3, in the walking motion, first, the heel A touches the ground first, then the sole B touches the ground, and when the foot is kicked forward, the heel is lifted as the foot is raised higher. It is gradually lifted higher, the ground contact point is transmitted from the outside of the foot to the front, the stress is in the direction of the arrow a1, and the side tread of the little finger C of the sole B (that is, from the first and fifth metatarsals). It is also referred to as a horizontal leg bow. This tread transmits stress while supporting weight. When the stress is transmitted to the thumb D in the direction of the arrow a2, it moves to a place where the stress is low, further forwards toward the skeleton position to the lowest tread (first metatarsal bone) in a lower place, and walks forward to As the height increases, the stress is transmitted in the direction of the arrow a3, the foot is kicked out, the thumb D moves away from the ground, and the walking motion is completed.

  For a person to walk comfortably, the stress must be transmitted from the outside to the inside, and the stress must be guided by the head between the high outside and the low inside. Therefore, when the insole body 1 is manufactured, it is formed according to the shape of the foot part of the human body, and the flexible insole body 1 having an appropriate thickness is used. The front foot portion 11 of the insole body 1 is provided with a tread surface portion 111 in which a portion corresponding to the thumb ball T of the foot portion of the human body is recessed and the thumb ball T abuts. The tread portion 111 can support the thumb ball T from which the forefoot portion of the human foot slightly protrudes, and the outside of the foot slightly protrudes from the outer support portion 112, and the forefoot portion is slightly inwardly inclined to support the outside. Since the side concave portion 113 in which the portion 112 extends downward is received on the outside of the sole and the outside of the foot sinks downward, the entire sole has a three-point positioning effect. As a result, the vertical force that the foot steps down is received, the force applied when walking is transmitted downward, the stress is transmitted smoothly, and the forefoot portion is slightly inclined inward. At the same time, the outer support portion 112 that extends outward from the tread portion 111 supports the front foot portion upward, and the inclined surface S is formed by being slightly inclined inward. When the heel is lifted, the stress from the side recess 113 is transmitted to the inclined surface S, the weight is applied to the inclined surface S, the stress is transmitted, and after the stress is transmitted to the thumb, it is kicked away from the ground. The insole of the present embodiment effectively corrects the sole inward, reduces the pressure applied to the foot by a normal or valgus sole, and the stress of the foot is easily transmitted along the guide path to exercise. The inertia of energy can be extended and the resistance can be reduced.

  In addition to the functions described above, the advantage of the present invention is that the insole body 1 is selectively used in and out of a shoe, and an effect that is easy to use is obtained. When putting on shoes, the insole body 1 is taken in and out as needed. Of course, the difference in the shape of each shoe or the function required for the shoe does not affect the insole structure of the present invention.

  Moreover, when the person who wears walks, the insole main body 1 may be provided with a thumb accommodating portion 114 that supports the thumb.

  As can be seen from the above description, when the insole structure of the present invention is used in combination with the insole body 1, the forefoot portion is slightly inwardly inclined and the normal or valgus sole is corrected inwardly and is in an accurate posture. Will be able to hold. In this way, the stress is transmitted from the outside to the inside, and the stress is guided by the head between the high outside and the low inside, so the stress is transmitted smoothly when walking, running, jumping, so it is easy and easy In addition to being able to move, it can prevent injury to the foot or spine.

As can be seen from the above, the insole structure of the present invention has the following advantages (1) to (4) as compared with the conventional structure.
(1) The front tread is tilted inward slightly and the insole is corrected inward by the indented tread surface so that the stress when walking on the ground is smoothly transmitted, making it easier and easier and improving comfort. To do.
(2) Since the inertia of the kinetic energy generated when walking increases and the resistance decreases, the feeling of fatigue can be greatly reduced.
(3) Due to the indented tread surface, the forefoot sole is slightly tilted inward, so that the sole can be corrected inwardly, reducing pressure on the lumbar spine and hurting when standing for a long time Can be prevented.
(4) When the insole body is inserted into the shoe, the sole can be corrected, and the insole body becomes thinner and lighter and the volume is reduced.
