Abstract

The invention provides an insole through consideration of skeletal structures of feet and continuous motions from foot joints to bodies. The insole supports three points of the soleso as to stabilize the center of gravity. According to the insole, the three points are supported from the sole side and refer to the first metatarsal sesamoid bone, the tuberosity of the fifth metatarsal bone and the calcaneal tuberosity, and the center of gravity can be stabilized by the aid of the three-point balance, so that stimulation can be provided to adjust body motions caused by the sole to help the body to return to the correct position.

Description

Shoe-pad

Technical Field

The invention relates to an insole. More particularly, the present invention relates to an insole which supports a sole of a foot at three points of the sole of the foot so as to enable a center of gravity to be smooth and suitable for sports.

Background

Although some insoles are primarily intended for deodorizing and comfort purposes, the insole of the invention allows for balancing to maintain proper position and to adjust the center of gravity for functional movement.

The skeletal system, muscular system, and nervous system may also be adversely affected when the foot joint (foot joint) is deformed. The skeletal system is affected so that when the foot joint (basal joint) of the base is deformed, the height of the left and right pelvis will be different, which in turn may cause lateral bending of the spine. Scoliosis may cause a variety of systemic impairments such as neurological disorders (neurological disorders), blood circulation failure (blood circulation failure), visceral disorders (viscercal disorders), and the like.

The musculature is affected so that when the foot joints are deformed, it is not possible to stand in a relaxed manner, as the muscles would work excessively to compensate for the imbalance. Therefore, muscles are often in a tense state, and thus lactic acid, which is a fatigue substance, is accumulated to cause fatigue. If this condition persists, the muscles solidify (cured), blood circulation failure occurs, and chronic shoulder stiffness and headaches are eventually induced.

The nervous system is affected so that when the spine is deformed, the nerves are compressed. This compression may lead to a dysfunction of neurotransmission because nerves extend from the spine to the whole body. In addition, when the spine is deformed, organs are also compressed, and thus visceral disorders may be induced. If this discomfort persists, pressure builds up and chronic pressure then causes an imbalance between sympathetic (sympathic nerve) and parasympathetic (parasympathetic nerve), which may affect hormone secretion (hormone secretion).

Figure 2 shows the adverse effects due to deformation of the foot joint of the base.

Disclosure of Invention

An object of the present invention is to provide an insole which can achieve comfortable exercise and stable balance. For this purpose, the insole of the present invention is made by considering bones when both feet contact the ground, the motion of foot joints, and the center of gravity, so that three-point balance is constructed with the sessile bone of the first metatarsal (first metatarsal Sesamoid bone), the tuberosity of the fifth metatarsal (heel metal tuberosity) and the calcaneal tuberosity as supporting points.

The purpose of the insole described in patent document 1 is to prevent toe eversion (hallux valgus). The insole has concave and convex parts to fix the foot in the shoe without moving, thereby preventing the eversion of the toes.

However, in the insole described in patent document 1, the structure of the foot joint is not considered, and the insole is not designed to support a specific position and cannot allow appropriate movement.

The purpose of the insole described in patent document 2 is to correct a flat foot. In the insole, a circular elevated member (circular elevated member) is provided at a middle portion of the insole to elevate navicular bone and cuneiform bone to correct the flat foot.

However, as in patent document 1, the insole described in patent document 2 does not consider the structure of the foot joint, and the insole is not designed to support a specific position and cannot allow appropriate movement.

The present invention provides an insole which is restricted from moving and is disposed inside a shoe to support a sole of the foot, wherein the insole has a convex portion which supports a tuberosity of a first metatarsal, a tuberosity of a fifth metatarsal, and a tuberosity of a calcaneus from a sole side when the insole is restricted from moving and is disposed inside the shoe.

The insole of the present invention has a flat profile shape, and the outer edge of the insole is fitted with the edge of the inner part of the shoe so that the insole can be located at a specific position when it is placed in the shoe. The three-dimensional shape of the insole has protrusions at specific locations. The convex portion is located at a position of a sessile bone supporting the first metatarsal, a tuberosity of the fifth metatarsal, and a calcaneal tuberosity from the sole side. This three point balance is most preferred as this is the most stable support means, as shown by the tripod. According to the invention, successive disabilities caused by the deformation of the foot joint of the base can be eliminated.

According to the present invention, it is possible to provide an insole which supports the sole of a foot at three points of the sole of the foot, so that the center of gravity can be stabilized and the exercise can be comfortable.

In particular, since the insole supports the sole of the foot at a proper position to achieve three-point balance, so that the center of gravity is stabilized and maintains a correct position, the insole can improve functional sports. In addition, the insole of the invention can eliminate the successive disability caused by the deformation of the foot joint of the base.

Detailed Description

Hereinafter, embodiments of the footwear insole according to the present invention will be explained with reference to the accompanying drawings.

Although fig. 1 and 3 show only the bones of the right sole and the insole for the right sole, the bones of the left sole and the insole for the left sole are mirror images of the bones of the right sole and the insole for the right sole, respectively.

The insole of the present invention improves functional sports by optimizing a standing position and adjusting the center of gravity, and thus the insole is applicable not only to conventionally used shoes but also to functional shoes for sports and the like.

First, in consideration of the structure, function and action of the insole, the skeletal structure of the foot will be explained to then explain embodiments of the insole of the present invention. Fig. 1 is a plan view showing the skeletal structure of a sole of a foot. This figure is viewed from the bottom side.

Fig. 3 shows insole 10 with features to stabilize the center of gravity by three-point balancing. In the insole 10, the seed bone contact portion (convex portion) 21 of the first metatarsal bone is in contact with the seed bone 11 of the first metatarsal bone, respectively; the tuberosity contact (convex) portion 22 of the fifth metatarsal is in contact with the tuberosity 12 of the fifth metatarsal; and the calcaneal tuberosity contact portion (convex portion) 23 is in contact with the calcaneal tuberosity 13.

The footwear insole 10 has a laminated structure consisting of three layers, i.e., a surface material layer 31, the surface material layer 31 being located on a side contacting with the foot; an intermediate base member layer 32; and a placement member layer (nesting member layer) 33, the placement member layer 33 being located on the side in contact with the shoe. Since the shape of the foot is different according to the individual using the insole, the thickness of each portion can be made different from each other by changing the thickness of each portion of the arranger layer 33.

For general use, a plurality of kinds of footwear insoles 10 may be prepared in advance corresponding to general foot shapes. Also, in order to make the surface material uneven, a separate convex member, which is attachable and detachable, may be installed on the surface of a previously prepared flat insole, or the convex member may be installed on an intermediate layer among a plurality of layers.

Specifically, as shown in fig. 3 and 4, the footwear insole 10 itself may be easily deformed to make the footwear insole movable, and the footwear insole also has a characteristic uneven structure in which the protrusions 21, 22 and 23 are formed at specific positions. The protrusions 21, 22 and 23 located at specific positions may be formed by separate protrusions.

The present invention provides an insole which is restricted from moving and is disposed inside a shoe to support a sole of a foot, wherein a surface or a rear surface of the insole has a convex portion to maintain three-point balance when the insole is restricted from moving in the shoe. The convex portion supports three points, so the center of gravity can be stabilized. It is to be noted that the projections 21, 22 and 23 may be replaced by recesses, each corresponding to each projection. In this way, the function of the concave portion is similar to that of the convex portion.

The present invention provides an insole which is restricted from moving and is disposed inside a shoe to support a sole of the foot, in a shape of which a surface or a rear surface of the insole has a function of maintaining three-point balance on the sole of the foot when the insole is restricted from moving in the shoe, and thus functional pressure is applied to the sole of the foot, wherein the three points correspond to a tuberosity of a first metatarsal, a tuberosity of a fifth metatarsal, and a tuberosity of a calcaneus, respectively.

The shoe insole 10 has a flat surface portion which is in contact with the shoe in which the shoe insole 10 is placed and which is located on the surface opposite to the surface provided with the convex portions, the flat surface portion being deformable by the convex portions. In this case, each convex portion may also be replaced by a concave portion.

Meanwhile, as illustrated in fig. 6, 7 and 8, circular concave portions 21a, 22a and 23a may be formed at the centers of the convex portions 21, 22 and 23.

As described above, since the insole of the present invention supports the sole of a foot at a proper position to achieve three-point balance, the insole can improve functional movement, thereby stabilizing the center of gravity and maintaining the correct position. In particular, the insole of the invention makes it possible to eliminate the successive disabilities caused by the deformation of the foot joint of the base.

Although a specific structure has been shown in the above-described embodiments for explaining the present invention, it is apparent that the present invention may be partially modified and the like.
