Description

SHOE HAVING ECCENTRICALLY-WEIGHT DISTRIBUTING SHOE SOLE FOR CORRECTING LOWER LIMB ALIGNMENT AND LOSING WEIGHT

The present invention relates to a shoe having an eccentrically-weight distributing shoe sole for correcting a lower limb alignment and losing weight, which can provide a weight loss effect through a kinetic effect to the same extent as a wearer lifts dumbbells during walking because a forefoot portion, an inner side or an outer side of the shoe is formed relatively heavier or a rearfoot portion, the inner side or the outer side of the shoe is formed relatively lighter, and which can correct O-shaped legs or X-shaped legs because the inner side or the outer side is formed heavier.

In general, gait of a human being is divided into a stance phase and a swing phase. The stance phase means the instant the foot contacts the ground, and accounts for approximately 60 percent of a normal gait cycle. The stance phase is subdivided into five phases: initial contact, loading response, midstance, terminal stance, and preswing.

Here, the Initial contact represents the beginning of the stance phase, and occurs the instant the heel of the foot touches the ground first. In this instance, the hip joint is bent, the knee joint is straightened, and ankle joint moves the top of the foot a little upward (dorsiflexion). Furthermore, the opposite foot is in the terminal stance phase. That is, it means a simultaneous stance phase.

Loading response, which is the second phase of the stance phase, occurs directly after the heel of the foot touches the ground. During loading response, the foot comes in full contact with the floor, and body weight is transferred onto the stance limb. The knee joint is bent a little in order to absorb impact to the transferred weight, so that the body weight does not transferred excessively. At the same time, the ankle joint moves down the foot (plantarflexion) and the opposite foot is in the preswing phase.

Mid stance, which is the third phase of the stance phase, occurs when the center of gravity of the body goes over the center of the sole of the foot. During this phase, the body weight is supported by only one foot, and the hip joint is straightened. In this instance, the ankle joint moves the top of the foot upward (dorsiflexion), and the opposite foot is in a midswing phase of the swing phase.

Terminal stance, which is the fourth phase of the stance phase, occurs when the hip joint and the knee joint are gradually straightened and the ankle joint carries out the movement to gradually move down the top of the foot to thereby prevent that the center of gravity of the body is excessively transferred to the front. In this instance, the opposite foot is in a terminal swing phase of the swing phase and prepares for the initial contact phase.

Preswing, which is the fifth phase of the stance phase, occurs when the contralateral foot contacts the ground and ends with ipsilateral toe off. In this instance, the hip joint and the knee joint are gradually bent, and the ankle joint carries out the plantarflexion. The opposite foot is in the loading response phase.

The swing phase means the period that the foot leaves the ground, and accounts for approximately 40 percent of a normal gait cycle. The swing phase is subdivided into three phases: initial swing, mid swing, and terminal swing. Here, the initial swing phase occurs after toe-off, and in this instance, a swing speed gradually increases through a motion that the foot swings in the air, and the hip joint and the knee joint carries out flexion. Additionally, the ankle joint carries out dorsiflexion, and the opposite foot is an early stage of the mid stance phase.

Mid swing, which is the second phase of the swing phase, is the final stage of the initial swing and the early stage of the terminal swing. The hip joint and the knee joint are gradually straightened while going through the central line of the body. In this instance, the ankle joint keeps the dorsiflexion state of the mid swing phase, and the opposite foot is in the final stage of the mid stance.

Terminal swing, which is the final phase of the swing phase, is a phase that the knee fully extends in preparation for heel contact. In this instance, the hip joint keeps a slightly bent state but the knee joint is fully straightened, and the ankle joint keeps the dorsiflexion state. The opposite foot is in the terminal stance phase.

Walking starts as the center of body weight is transferred forward. A human being walks while moving the center of body weight forward by moving weight of a part of his or her body forward.

It is the most idealistic to lift up the leg and straighten up the upper body when weight of a part of the body is put forward for walking. However, persons with a rapid pace or persons with weak muscle strength at the lower limbs put their heads forward. When the head is put forward, the back is naturally bent to thereby cause musculoskeletal disorders. Such a symptom increases while the wearer wears high-heeled shoes. The reason is that the high-heeled shoes cause an instable posture due to a forward movement of the center of gravity. In this instance, the upper body is bent forward and the hips are pulled back in order to prevent that the wearer falls forward due to the forward bending of the upper body. Accordingly, the human body has two centers of the upper body and the lower body: one being a hip joint-centered line; and the other being a spine-centered line. Then, impact to the waist grows up and it may cause backache.

As the level of income has increased with the development of industries, the basic food, clothing and shelter problems have been solved, but health-related problems, such as stress, adult diseases, obesity, and so on, have become serious social problems. In the meantime, recently, the whole nation is growing more and more interested in health due to the advent of the well-being era. In such a context, exercise, orthotherapy, diet, and so on, has recently become the main interest among not only women but also men. With the trend of society, heelless shoes for losing weight have been invented. When a wearer wears the heelless shoes, because the center of the foot naturally moves toward to the tiptoe and the wearer walks in a bouncy gait, power is concentrated on the abdomen and the legs and muscles of the calves and the femoral muscle are repeatedly relaxed, whereby it improves muscular strength and endurance to thereby provide a weight loss effect.

However, the shoes have a problem in that they do not provide a posture correction effect because they have been invented to induce the bouncy gait by concentrating body weight on the toe portion of the foot in order to provide a marathon race effect or a run race effect even while walking. Moreover, the conventional shoes have another problem in that they do little to lose weight due to a poor kinetic effect.

Accordingly, the present invention has been made in an effort to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide a shoe having an eccentrically-weight distributing shoe sole for correcting a lower limb alignment and losing weight, which can provide a weight loss effect through a kinetic effect to the same extent as a wearer lifts dumbbells during walking because a forefoot portion, an inner side or an outer side of the shoe is formed relatively heavier or a rearfoot portion, the inner side or the outer side of the shoe is formed relatively lighter, and which can correct O-shaped legs or X-shaped legs because the inner side or the outer side is formed heavier.

To achieve the above objects, in an aspect, the present invention provides a shoe having an eccentrically-weight distributing shoe sole for correcting a lower limb alignment and losing weight, which includes a shoe sole and an upper, the shoe sole having an insole and an outsole, wherein the insole or the outsole has a high-gravity member formed at a forefoot portion thereof in such a way that the forefoot portion is relatively heavier than a rearfoot portion thereof or a high-gravity member formed at an inner side or an outer side thereof in such a way that the inner side or the outer side is relatively heavier than the other side of the insole or the outsole.

In this instance, the insole includes at least one of an inner sole and a midsole.

Moreover, in the insole or the outsole, the forefoot portion having the high-gravity member is thicker than the rearfoot portion.

Furthermore, the high-gravity member is in the form of a bar, and a plurality of the high-gravity members are arranged in a horizontal direction or in a vertical direction.

Additionally, the high-gravity member is in the form of a pole, and a plurality of the high-gravity members are arranged.

In another aspect, the present invention provides a shoe having an eccentrically-weight distributing shoe sole for correcting a lower limb alignment and losing weight, which includes a shoe sole and an upper, the shoe sole having an insole and an outsole, wherein a forefoot portion, an inner side, or an outer side of the outsole are relatively thicker than the other side of the outsole.

In a further aspect, the present invention provides a shoe having an eccentrically-weight distributing shoe sole for correcting a lower limb alignment and losing weight, which includes a shoe sole and an upper, the shoe sole having an insole and an outsole, wherein the insole or the outsole has an empty space or a low-gravity member formed in a rearfoot portion, an inner side, or an outer side to make the rearfoot portion, the inner side, or the outer side to be relatively lighter than the other side of the insole or the outsole.

In a still further aspect, the present invention provides a shoe having an eccentrically-weight distributing shoe sole for correcting a lower limb alignment and losing weight, which includes a shoe sole and an upper, the shoe sole having an insole and an outsole, wherein the insole or the outsole has a high-gravity member inserted into a forefoot portion, an inner side, or an outer side of the insole or the outsole to make the forefoot portion, the inner side, or the outer side be relatively heavier than the other side of the insole or the outsole.

According to the present invention, the shoe has the forefoot portion heavier than the rearfoot portion because the forefoot portion of the shoe sole has the high-gravity member or the rearfoot portion has the low-gravity member of the empty space, whereby the shoe can provide a weight loss effect through a kinetic effect to the same extent as a wearer lifts dumbbells during walking.

Furthermore, the present invention can increase a kinetic effect by promoting walking and increasing an exercise period of time and walking speed because the shoe transfers the center of gravity of the wearer forward and makes plantarflexion quicker and smoother at the moment that the heel lands on the ground.

Moreover, the present invention can correct O-shaped legs by inducing eversion moment to face the sole outward in the swing phase and inducing a rotational force to move the knees inward by rotating the shin outward by the law of action and reaction at the ankle joint.

Additionally, the present invention can correct X-shaped legs by inducing inversion moment to face the sole inward in the swing phase and inducing a rotational force to move the knees outward by rotating the shin inward by the law of action and reaction at the ankle joint.

In this instance, in case that the empty space 130 is formed, the insole 110 or the outsole 120 may further include a plurality of supporters 131 to support the wearer`s weight.

When the empty space 130 or the low-gravity member 130 is formed on the inner side of the shoe sole 100, because the outer side of the shoe 10 gets heavier, X-shaped legs can be corrected. Moreover, when the empty space 130 or the low-gravity member 130 is formed on the outer side of the shoe sole 100, because the inner side of the shoe 10 gets heavier, O-shaped legs can be corrected.

(Embodiment 15)

FIG. 26 is a side elevation view of a shoe for losing weight according to a fifteenth preferred embodiment of the present invention, and FIG. 27 is a perspective view of a shoe sole according to the fifteenth preferred embodiment. As shown in FIG. 26, the shoe 10 according to the fifteenth preferred embodiment includes the shoe sole 100 and the upper 200.

Here, the shoe sole 100 is made of a material, which is not easily deformed or damaged by external impact or pressure caused by a wearer`s body weight. However, preferably, the shoe sole is made of synthetic resin or a rubber material. Moreover, more preferably, the shoe sole is made of ethylene vinyl acetate (EVA), phylon, polyurethane (PU), or rubber.

In this instance, as shown in FIG. 27, the forefoot portion of the shoe sole 100 has a high-gravity member 102 heavier than a rearfoot member 101 of the shoe sole 100. The high-gravity member 102 has a form corresponding to that of the forefoot portion of the shoe sole 100 within a range of 0% to 70% of the forward longitudinal direction of the shoe sole 100, and is formed integrally with the rearfoot member 101 of the shoe sole 100 through press working and injection-molding or bonded integrally with the rearfoot member 101 using adhesives for bonding shoe soles. However, if necessary, the high-gravity member 102 may be formed in an attachable and detachable manner. The high-gravity member 102 is made of high-gravity synthetic resin, high-gravity polyurethane, high-gravity rubber or metal, which is heavier than the material of the shoe sole 100.

While the invention has been described with reference to particular matters, limited embodiments and drawings, it will be understood by those skilled in the art that the invention is not limited to the particular embodiments disclosed since the embodiments are disclosed in the present invention for better understanding of the present invention, but various changes may be made and equivalents may be substituted without departing from the scope of the invention.
