Abstract

The present invention relates to a shoe capable of training the muscles of the lower limb in a balanced way just by simply walking, and a manufacturing mold thereof. More specifically, the invention naturally promotes correct gait posture when wearing the shoes. To this end, the present invention allows natural motion of an extruder kicked by the big toe at a support in which the entire sole of the foot comes in contact with the bottom thereof to allow body weight to be put on the support, and continuously maintains a 55 degree angle, thereby enabling balanced training of the muscles of the lower limb and correct walking gait.

Description

A low weight midsole having a laterally penetrated hole to be integrally formed, and an apparatus for manufacturing the same.

The present invention, while having a through-hole penetrating to the side of the midsole to be integrally formed to implement a low weight while implementing the convenience of walking, to minimize the defects to facilitate the manufacture of such a midsole.

As society develops, interest in health gradually increases, and individuals are spending a lot of money due to participation in fitness-related fitness and various sports-related sports, but side effects are caused by excessiveness.

Therefore, in recent years, many people are interested in low-cost, no side effects and health-friendly walking, but such walking is not expected to exercise much unless the exact walking, as well as side effects.

If you walk now, more than 90% of the muscles of the human body are used, and fast walking consumes a lot of calories, which is effective in the diet, and regular walking increases the good cholesterol (HDL) while preventing bad cholesterol (LDL) from accumulating in the body. An increase in good cholesterol is a heart attack. It is known to reduce the risk of osteoporosis, high blood pressure, diabetes and the associated complications, and increase motility in patients with arthritis.

In addition, this walking has a positive effect not only on the health of the body but also on the mental side. Recently, many people walk because it is known to be effective for the prevention and treatment of cancer. It is.

This is generally because people with mental illness are less likely to develop cancer or other diseases because they are not living under stress.

The following diseases can help walking.

Heart disease: Lively walking is good for your heart. The heart is basically a muscle.

Your blood pressure goes down, your cholesterol levels are lowered, and your risk of heart attack is close to 50%.

Weight management: As you get older, you can't manage your weight simply by limiting your food intake. If you walk vigorously for more than 30 minutes a day, you will not only burn hundreds of calories, but also boost your metabolism, which will help you manage your weight.

This is because walking is also effective in reducing body fat.

It is important to note that you will lose 300 Kcal if you walk at least one hour a day, because your body fat will not burn as soon as you start exercising, but will burn out after 20 minutes of activity. .

In this regard, vigorous exercise can be counterproductive to burning body fat in that it can bring about exhaustion even before full-fat burning begins.

Diabetes: Lively walking for 30 minutes a day has been shown to prevent diabetes.

It is especially good for people with diabetes who are overweight and metabolic, and almost twice as effective as prescription.

Osteoporosis: Walking will strengthen your muscles as well as your bones. Women who regularly exercise calcium in their 20s and consume adequate calcium will have a 40% lower chance of developing osteoporosis in their 70s.

Arthritis: More than 3 million Americans are known to suffer from arthritis of the knee, and walking helps strengthen arthritis around the knee, especially in swimming pools.

Depression: Everyone knows that breaking news is good for diversion, but short-term effects are less effective, but patients who have been steadily exercising for about 10 months without taking antidepressants get sicker than those who take antidepressants without exercise. It is known to have improved.

Cancer: More research is needed, but studies have shown that walking can also play a role in cancer prevention and treatment.

In addition, it is important to walk in the correct posture because such walking can lead to chronic musculoskeletal disorders if the posture is long.

However, the basics of such walking can be found in foot health.

When we grew up on the ground, we wore a lot of rubber shoes, but the orthopedic problem was not as serious as it is now.

However, as the asphalt, cement, and sidewalk block cultures develop, it is known that the cause of acquired flatfoot, especially wrong shoes, is caused by deformation of the foot as an orthopedic problem of the human body.

Our human body consists of 206 bones, one quarter of which make up the foot. It consists of 52 bones, 26 each on one foot.

In addition, the skin area of the foot is only 3% -5% of the entire body, but 5% of the area supports 95% of the body.

Therefore, sometime we express the foot as a second heart, which requires the power to send blood repeatedly to contract and relax in order for all the blood to rise back to the farthest toe by the pumping of the heart. Because it plays a role.

However, this pump action is called the second heart because the foot (foot) is to allow the blood to circulate through the act of walking or running using the foot.

However, these feet are ultimately measured by the lower extremity muscles that induce the movements of the feet. Particularly, repetitive walking causes the lower extremity muscles to contract and relax, thereby raising blood far from the heart to the heart. Because it is playing a role.

Therefore, healthy feet should not be pain when walking, keratin, callus, edema, deformation, cold should be healthy feet.

In order to be healthy, cold blood of the lower body goes to the head, and the head is cool and the hot blood circulates to the lower body, and the feet become warm and healthy.Most of the general people are cold and the head is full of heat, causing stress or headaches. Problems will arise.

Therefore, walking is a community of comprehensive movements such as foot movements, knee movements, hip movements, arm and shoulder movements, and head movements.

That is, it is a basic problem to keep your back straight, chest straight, your head pulled your chin forward, and your arms to shake while walking. It is divided into pottery and pottery, which can be further subdivided. First: heel wearer (second stance) Second: whole foot rests on the floor (support) Third: strong extruder (thumbs), fourth: knee This curved, falling foot moves from the ground. Fifth: It is subdivided in the form of (forwarding) foot, which is important as the foreground angle of the sole (the angle of the sole viewed from the front) when one foot moves forward.

In other words, it is important to see how much the sole is seen from the front of the pedestrian, and at least 25 degrees of the foreground angle should be maintained at the stance and at the rear of the pedestrian when extruder extruded, ie the heel lifts the weight and moves to the big toe. It is important that the angle of the sole of the foot is 55 degrees.

Therefore, it is proposed to maintain the foreground angle of 25 degrees in the shoe without the heel pre-registered by the applicant, but the problem that it was impossible to always make the angle of the sole of the foot seen from the rear of the pedestrian in the extruder always 55 degrees.

In other words, most of the extruder extruder by training the attitude of the extruder to 55 degrees by the consciousness of the pedestrian, but the training was always impossible to maintain the angle of 55 degrees.

Therefore, the result of walking did not get the effect of walking by correct walking.

In other words, the whole sole of the sole touches the floor, and the extruder that kicks the body with the big toe from the supporter that loads the weight is not precisely made, and most of the knees are bent and put a lot of stress on the knee.

Therefore, it is possible at the time of accurate walking, but during normal walking, such parts are not accurately repeated, which does not sufficiently generate the health benefits of walking.

Therefore, the present invention allows the balance of the lower extremity muscles to be uniformly maintained by maintaining the angle of 55 degrees while the operation of the extruder kicking with the big toe naturally occurs in the supporter on which the entire sole of the foot touches the floor. It is possible to walk correctly while going.

For this purpose, the structure of the midsole is to be able to walk 11 feet and 3 beats by making the heel part and the front heel part have a certain inclination angle in the part where the entire sole of the foot touches the floor in the state of supporting the weight.

In other words, the angle of the sole of the sole from the front should be maintained at 25 degrees or more in the heel stopper, and the angle of view from the rear of the extruder, which is strongly kicked by the big toe from the supporter where the entire sole of the sole touches the floor and loads, is 55 By maintaining the degree, the knee is bent and the foot falls from the ground (soil) so that no stress is transmitted to the knee at all, so that the foot is easily moved to the forward moving forward.

Therefore, when the midsole distribution is in close contact with the bottom surface of the midsole in the supporter, a constant inclination angle is formed in the heel and front heels, so that the back muscles of the lower extremity muscles are pulled in the heel attacher and the entire sole of the foot When the weight reaches the extruder that is strongly kicked by the big toe from the supporter that puts the weight on the body, the weight makes the anterior muscles tense so that the back muscles and the anterior muscles of the lower extremity muscles can be balanced. Lower body strengthening will benefit other health.

Therefore, if the knee is bent in the extruder and the foot is moved from the ground to the mobile device (legator), and the foot is moved forward in the form of a forward machine, there is no inclination of the knee joint and there is no stress of the joint to maintain comfort Will be helped to strengthen the pelvis according to the use of the pelvic muscles.

In addition, wearing ankle pumps not only creates a stable shape of the knee when walking and walking. Posture by developing muscles that are not commonly used but do not contribute significantly, such as the gastrocnemius muscles of the lower thigh, equipment bone, thigh muscles, quadriceps muscles, thigh biceps muscles, intestinal psoas muscles, and erect spine muscles. You can see the effect of making it right.

The present invention is that in the midsole to be sealed by the capping and sewing means or the adhesive means, the heel portion is removed in an arch shape,

Wearing the shoe made of the midsole, in the heel landing for the first floor stepping (walking angle) in the step of walking in the state in which the angle of the sole from the front of the midsole to maintain a certain angle (about 25 degrees) inclined The heel portion with the inclined surface

A support surface having a plane in which the weight to be moved upright to the extruder, which is a walking step, from the supporter on which the entire sole of the foot touches the floor while the weight is moved forward from the landing

The front ankle part forms an inclination angle such that the angle of the sole of the back of the midsole is inclined at a predetermined angle (about 55 degrees) while the weight is moved forward to move forward from the support surface. It is characterized by consisting of.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 10, the configuration of the present invention is the heel landing for the first floor stepping is divided in the walking step of the midsole 100 is sealed by the gatpi 200 and sewing means or adhesive means In the stand, the weight of the sole is inclined at a certain angle (around 25 degrees) in front of the midsole, while the weight is moved forward, and the entire sole of the foot touches the floor. When crossing, the angle of the soles visible from the rear of the midsole is formed to have an inclination angle inclined at a predetermined angle (about 55 degrees).

To this end, the support surface 10 and the rear of the support surface 10 are formed of a constant horizontal surface for stable maintenance of the part where the sole touches the floor in the supporter on which the entire sole of the sole touches the floor. This condition (i.e., the back muscles) is formed by forming an inclined surface 21 having an inclination angle so that the front of the sole is lifted up by a certain angle before the heel is first touched the floor in the standing position before the support. Pulled state) is instantaneous but has a certain length to allow a certain amount of time delay, and the support surface (10) to which the entire sole of the sole touches the floor in the heel portion (20) to load the entire weight (10) ) Is divided into a front bent portion 30 for passing to the extruder, the inclined angle (31) at a predetermined angle on the support surface 30 a) is formed.

At this time, the inclination angle (31a) of the forefoot portion may be formed as an inclined surface (31) made of the same shape as the inclined surface (21) for a stable landing at the time of landing, such as the heel portion (20), by the step 32 The jaw can be formed as a step surface 33 in the form.

In this case, when the stepped surface 33 is formed, the front muscles are moved forward by the step 32 in order to move forward with the extruder for advancing during walking by inducing an accurate extruder to transmit a strong force to the toe area. Will induce pressure or pull.

That is, the inclined surface 31 of the front bent part 30 is different from the inclined surface 21 of the rear bent part 20, and the inclined surface 31 at the time of extrusion for moving forward by the front bent part 30 is the support surface. (10) There is a disadvantage that walking cannot be achieved because it is precisely divided into steps from the supporter, which is the walking stage, to the extruder in the step (10), while stability is achieved by the smooth continuity when moving from the supporter, which is the walking stage, to the extruder. On the other hand, the step surface 33 by the step 32 has a merit that the pace is correctly maintained due to the advantage of being passed by the correct step to the supporter and the extruder, which is the step of walking accurately, while the continuity is maintained. There may be a disadvantage that the sense of stability may fall depending on the wearer falling apart in strength development.

Therefore, when the inclined surface 21 of the heel portion 20 first touches the floor in the staging phase of the walking step, the pulling of the back muscles of the lower limb naturally occurs, and the heel heel is moved to the supporter during the walking phase in that state. The angle of inclination at the boundary line 40 separating the heel portion 20 and the support surface 10 while the back muscles pulled by the inclined surface 21 of the portion 20 remain intact (the ground surface is from the front side). The upper body is lifted and the back muscles are pulled up by the pelvis rather than the knee, while the upper body is lifted by the angle shown. In this case, the big foot by the inclination angle (angle seen from the rear while being lifted up to the ground) formed in the forefoot portion 30 while passing from the support surface 10 to the forefoot portion 30. Not as strong pull and pressure generated in the lock and the front muscles that will not only enable the training back muscles and balanced gait in front of the muscle.

At this time, between the support surface 10 and the heel portion 20 to form a constant inclination angle (21a) of the front heel portion 30 is raised from the heel portion 20 by the boundary line 40, the inclination angle (21a) is the front for the landing of the heel portion 20 when the heel portion 20, which is divided into the bottom and the inclined surface 21 and the boundary line 40, which is divided into the bottom for the first time, touches the floor. In the present invention, by applying the angle of lifting the bottom surface of the bore midsole 100 in the range of at least 25 ° ~ 45 ° it was confirmed that the pull and compression of the back muscles and front muscles is generated uniformly.

At this time, the angle of inclination of 25 ° or less may be provided, but in this case, the back muscles may not be pulled smoothly and sufficient exercise effects cannot be expected.

In addition, if the 45 ° or more is the most pulling occurs due to anxiety when walking unsuitable problems occur.

In addition, the division of the rear bent portion 20 in which the support surface 10 and the inclined surface 21 of the midsole is formed is the support surface 10 when the total length of the midsole 100 is 100 based on the boundary line 40. ) Was 60 to 65, and the heel portion 20 was set to 35 to 40.

At this time, the front surface of the support surface is longer than the big toe portion

In the present invention, the front end of the metatarsal bone formed at the rear end of the big toe is set to 17% so that the advancement is easily performed when the walking step is advanced.

However, if the length ratio of the heel portion 20 may be 30 or less, in this case, because the heel portion 20 may not be maintained for a predetermined time in contact with the floor for the first time, the heel portion necessary for pelvic walking ( When the inclined surface 21 of 20) lands on the floor and moves to the supporter from the walking stage, the support force for pulling the back muscles is dropped while being passed directly to the supporter. It will cause insufficient problems.

In addition, when the length ratio of the heel portion 40 to 40 or more, when passing from the standing position to the supporter, a certain time is delayed and the back muscles are pulled, and the supporter should naturally go to the supporter. It is to provide a discomfort in the walking forward and to solve this, it is possible to cause a chronic musculoskeletal abnormalities due to the action of the excessive joint.

In addition, if the front anterior part of the support surface is located at the rear end of the metatarsal bone of the big toe or phalanges of the front end, it is not easy to fall forward when moving forward.

In addition, the front of the lower extremity muscles when the front heel portion 30 is lifted from the rear heel portion 20 in a state where the front heel portion 30 is held in a range of 25 ° to 45 °, and is transferred from the landing machine to the extruder for the advancement of walking. In order to cause the pulling and compression of the muscles, when the heel portion 20 of the midsole is lifted from the extruder, the lifted angle viewed from the rear should be maintained at 55 ° for a certain time to strengthen the muscle strength by pulling the front muscles. For this purpose, in order to facilitate such a fall when the front surface of the front bent portion 30 from the support surface 10 for this purpose, the step surface 33 is formed by the step 32 on the front bent portion 30. It is formed.

In addition, without forming the step 32, the forefoot portion 30 is formed from the support surface to the inclined surface 31, so that the training of the lower extremity muscle is insufficient, but to have the convenience of walking.

Therefore, the angle of the soles seen from the front is maintained at 25 degrees or more in the heel stopper, and the angle seen from the rear is 55 degrees in the extruder, which is strongly kicked by the big toe in the supporter that loads the weight by touching the entire sole. By keeping the knees bent and the foot falls from the ground (soiler) is not at all stress is transmitted to the knees will be easy to move to the advancing foot forward.

At this time, in the midsole in which the inclined surface 21 of the heel portion 20 is formed, a buffer hole 22 penetrating laterally is formed, so that the impact transmitted to the joint or the head of the human body by the load of the human body when landing with the floor. When the shock absorber is reduced, the impact is reduced, and when moving to the supporter in the state, the boundary line is advanced in the upright state (the state of the waist straightened) by the stepping force and the boundary line 40 due to the repulsive force. 40 is also formed in the midsole is formed by the buffer hole 41 penetrating laterally in the diagonal direction (the direction to move forward) on the upper side where the boundary line 40 is formed, so that the natural walking is made by the buffer when moving forward.

In addition, in the present invention, when the midsole of this type is formed, the portion where the boundary line 40 is formed is thickened so as to implement the inclination angle 21a of the heel portion 20 and the inclination angle 31a of the front heel portion 30. Due to the weight of the midsole itself, the weight of the midsole itself prevents the consumer from seeking lightness, so that the opening 11 is formed through the middle portion of the support surface 10 of the midsole to realize low weight. It is easy to bend the midsole during extrusion in the walking step.

At this time, the opening width of the opening 11 is not larger than the width forming the support surface 10, so that the insole is kept flat when worn.

In this case, the support surface 10 formed on both sides of the opening 11 allows the buffer holes 12, 13, and 41 to be penetrated laterally so as to absorb the impact during walking as well as low weight.

The opening 11 of the support surface of the midsole can be formed to form the opening 22 in the heel portion 20.

In addition, in the case of forming the buffer holes 12, 13, and 41 formed to penetrate laterally to the support surface 10 formed separately from both sides of the openings (11, 22) as described above, the openings (11, 22) As a result, the mold for forming the buffer holes 12, 13, and 41 can be prevented from being frequently damaged.

That is, when the structure of the mold does not form the opening 11 in the support surface 10 of the midsole as shown in Figs. 11 to 17, in order to form a buffer hole penetrating to the side of the support surface, the shape of the midsole is As a result, the same axial axis as the shape of the buffer hole is formed inward from the side wall of the inner mold of the lower mold where the inner mold is formed, and the ends of the axial shafts should be in close contact with each other while the lower mold is closed. In order to prevent the molded product from being caught, a packing having a cushioning force, such as rubber, is formed. Such packing is frequently damaged by foaming pressure, and as a result, productivity is reduced and cost increases due to such damage. Even when molded, the packing may not be damaged, as well as accurate contact of the shaft. If there would have been a problem, such as that caused a buffer hole is clogged in the middle of generation.

However, in the present invention, in order to form the opening 11 in the lower mold 50 having the inner part 51 and the support surface 10 of the molded midsole, the shape of the midsole in the state in which the upper mold 60 is covered As the inner space is formed, the protrusion 52 is formed at a position where the opening 11 is formed in the middle of the lower mold 50 at the support surface 10 of the midsole. After the inner groove 53 is formed as a side wall of the sidewall, the tip of the protrusion 54 protruding from the side wall of the inner portion 51 of the lower mold 50 is formed in the inner groove 53. In the case of forming the buffer holes 12, 13, and 41 penetrating to the side of the support surface 10 of the midsole, the buffer holes 12, 13, and 41 are free from defects while preventing frequent damage of the mold. ) To facilitate molding.

In the present invention, the protrusion 54 may be formed to protrude integrally from the sidewall of the indent 51, or the protrusion 54 may be formed to penetrate into the indent 51 from the outside of the lower mold 50. will be.

As described above, when the protrusion is integrally formed on the side wall of the inner part, the lower mold is operated left and right while being divided into equal parts, and the lower mold is made when entering the outside of the lower mold. In the state consisting of only the stone shaft is to operate.

This can be changed in various forms according to the way of productivity or the structure of the mold according to the opening and closing method of the upper mold and the lower mold.

In addition, a rubber packing is formed in the indentation groove where the tip of the stone shaft or the tip of the stone shaft is in close contact. If the rubber packing is not used, the tip of the stone shaft is formed with a precisely processed curved protrusion. By forming the inner groove into the curved groove to engage with it, the molding is excellent when foaming due to the close adhesion during molding due to the precise contact surface without using unnecessary rubber packing.

In addition, three buffer holes are formed in the support surface of the midsole, and buffer holes are formed in the upper side of the inclined surface of the heel portion, so that the cushioning at the landing stage is smooth and the buffer is smooth when the supporter is transferred from the extruder to the extruder. Will be maintained.
