Description

Outsole of shoes

The present invention relates to a shoe outsole, and more particularly, to a shoe outsole which can sufficiently transmit a force of a wearer to a ground surface through a shoe without slipping so as to increase a propulsion force and increase a walking speed and a traveling speed, The force applied to the second toe, the third toe, the fourth toe, and the toes of the toes as well as the force applied to the toe portion can generate the thrust, thereby further enhancing the propulsive force, and the toe- And the back-and-forth axis corresponding part is formed to be upward sloped toward the rear, so that the back-up elastic deformation and the upward elastic restoring process of the toe-corresponding part and the back and forth part corresponding part by the force applied by the weight of the wearer are repeated, Without buffering itself. And a plurality of cushioning portions are provided on the sole portion corresponding to the sole and the cushion portion corresponding to the heel and back so that the cushioning effect can be obtained by itself and the foot is prevented from slipping rightward or leftward when the force of the wearer is biased to the left or right side The wearer does not lose balance and falls, does not suffer an ankle injury, and does not lose the propulsion force, making stable walking and running possible. By centering the center of gravity toward the tip of the outsole, The present invention relates to a shoe outsole which helps a tip end to be inclined downward toward the ground, thereby enabling a fast running to be efficiently performed.

The most basic means of human movement is walking (Gait) and running (running).

Walking and running by human means mechanically moving the center of gravity of human being. In other words, human walking is carried forward by alternating the left and right legs forward and shifting the body weight to the front legs in turn.

When looking at one leg during walking and running, the flexor muscles and the extensor muscles move antagonistically, the left and right legs perform the same motion, and the upper and lower limbs As a result, a smooth and efficient walking is achieved.

The human foot is provided with a toe 21, a second toe 22, and a third toe 31 having recesses 31, 32, 33, 34, and 35 between the sole 10 and the distal end of the sole 10 23, a fourth toe 24 and a toe 25 and a back foot 40 located at the rear end of the sole 10.

One cycle of walking refers to the moment when the foot of the foot of the foot touches the ground and then falls back to the ground. One cycle of the walking includes the "Stance Phase" (see FIG. 1) in which the foot touches the ground, And a " Swing Phase " (see Fig.

"Standing" occupies about 60% of one cycle, and "Shaking" occupies about 40% of one cycle.

The term "standing" refers to "Heel Strike", "Foot Flat", "Mid Stance", "Heel Off" and "Toe Off" (See Fig. 1).

The " heel land contact " is a time when the footrest shaft 40 touches the ground. At this time, the force exerted by the shoe wearer is concentrated on the heel of the foot 40, as shown in the left part of FIG.

The "reaching the soles of the soles" is a time when the soles of the feet (40) touch the ground and the soles (10) touch the ground. At this time, the force exerted by the shoe wearer is distributed in the regions of the back foot 40 and the sole 10 as shown in the left-hand side of FIG.

The " intermediate standing " is the time when the center of gravity passes through the center of the sole 10 after the sole 10 touches the ground. At this time, the force exerted by the shoe wearer is distributed to the heel axis 40, the sole 10, and the toes 21, 22, 23, 24, and 25 as shown in the left part of FIG. do.

The " peeling of the heel of the foot " is a period when the heel of the foot 40 is separated from the ground after the middle standing. At this time, the force exerted by the shoe wearer is distributed to the front portion of the sole 10 and the toes 21, 22, 23, 24 and 25 as shown in the dark portion of the fourth figure from the left side of FIG.

The "toe-up" is the time when the toes (21, 22, 23, 24, 25) fall off the ground. At this time, the force exerted by the shoe wearer is distributed to the front part of the toe 21 of the sole 10 and the toe 21 of the toe as shown in the hatched portion of the fifth figure from the left side of Fig.

Here, " reaching the ground of the foot of the foot ", " reaching the ground of the sole of the foot ", and " standing of the middle " are regarded as preparations for obtaining the driving force. .

Particularly, the "toe-tearing" period is an important time for pushing the toe portion backward, that is, kicking motion to generate driving force.

"Shaking" is subdivided into "chasing", "shaking forward", and "entering" (see FIG. 2).

On the other hand, the driving cycle is similar to the walking cycle, but the "standing" is subdivided into "ground contact", "neutral standing", and "propulsion unit", and "shaking" is divided into "Follow Through" Swing " and " Foot Descent ".

The difference between walking and running is that there is a "Flight Phase" where both feet touch the ground when walking, while two feet do not touch the ground when driving.

In a running cycle, such as jogging or a marathon, the "standing" is longer than the "flying", and the "standing" becomes shorter as the running speed is increased such as 100m running.

In the case of a slow running, as in the case of a walk, the footbed contacts the ground first, and the toe touches the floor later. In a fast running, the footbed and the forefoot almost touch the ground immediately before the toe- Just before the toe is removed, the heel is lowered to the ground.

During a very fast run, only the forefoot (the tip of the soles and the toes of the soles) touches the ground, ranging from "land touch" to "propeller."

On the other hand, humans are known to have begun to wear shoes about 20,000 years ago, and since then shoes with various shapes and functions have been continuously developed.

The types of shoes are classified according to their shapes, materials, applications, and manufacturing methods. Basically, they can be classified into shoe or shoes type shoes including shoes sole and upper, and slipper type shoes including sole shoes and band.

Most of the sole is composed of outsole, midsole and insole, but sometimes it consists of outsole and insole only.

The outsole is required to have a cushioning function, light weight and abrasion resistance because it is directly impacted from the ground as a part touching the ground. Natural rubber and synthetic rubber, foamed vulcanized rubber, foamed EVA and polyurethane are used as the material of the outsole.

The midsole is attached to the upper surface of the outsole and is required to have a function of preventing the twisting of the shoe and a cushioning function. EVA sponge, pylon, polyurethane or the like is used as the material of the midsole.

The insole is attached to the upper surface of the midsole and is in contact with the sole, and the sole protection function is required. As the material of the insole, latex foam, EVA sponge, polyurethane and the like are used.

In the conventional outsole, since the toe corresponding part is simply formed in a flat shape, slippage occurs between the toe and the toe corresponding part during the kicking motion in which the toe is pushed backward at the toe peeling time, There is a problem in that the propulsive force is lowered in comparison with the force, resulting in a waste of physical strength.

Also, as shown in FIG. 3, while the force applied by the wearer concentrates on the thumb toe during the peeling of the toe, the force is not exerted only on the big toe, but on the second toe, the third toe, Since the upper surface of the toe corresponding portion of the conventional outsole is formed in a flat surface, the contact pressure to the toe corresponding portion due to the force applied to the big toe is strong, while the remaining toe, third toe, The contact pressure to the toe corresponding part due to the force applied to the toe becomes weak or hardly appeared.

Thus, the force exerted on the big toe is used to obtain the propulsive force, but the force applied on the second toe, third toe, fourth toe and toes is not used to obtain propulsion.

As a result, only the force exerted on the big toe, which is part of the force exerted by the wearer, is used to obtain propulsion, while the forces applied to the remaining second, third, fourth and toes are lost, And the waste of physical strength is increased.

In addition, when a curve is run in a track game or when a fast turn is made in other ball games, force is applied to the inside or outside of the foot. In this case, only the inside edge or the outside edge of the shoe is strongly adhered to the shoe, The side slip occurs because it is in a state of being lifted from the shoe. As a result, not only the propulsive force is lowered but also the wearer may be injured in the foot and ankle.

Particularly, in the course of rapidly changing direction in a track game or other ball game, the toe side is strongly pressed, and slip between the toes and the toe counterparts causes the wearer to lose balance and fall There is a problem that the young toe part is seriously injured.

In general, it is effective to employ a hard outsole for enhancing the propulsion force of the shoe, and it is effective to employ a soft outsole for the buffering effect.

Therefore, in the conventional shoes, a rigid outsole is incorporated by combining the same, and a separate buffer means such as a buffer rubber or a tubular member is combined.

However, such a buffering means can obtain a buffering effect, but deteriorates the effect of transmitting the force of the wearer to the ground.

As a result, the conventional shoe has a limitation in meeting both the function of transmitting the force of the wearer to the ground and the buffering function at the same time.

A fast run is also made up of standing, including neutral, standing and propelling, and wagging, including chasing, wiggling, and throwing, and the toes first touch the ground when the wearer touches the ground Conventional outsole is not centered on the center of gravity, so it does not help the landing motion.

Therefore, it is insufficient to give stability and driving force of fast driving.

As a prior art, Korean Patent Laid-Open No. 10-2011-0040653 (Apr. 20, 2011) discloses a "shoe equipped with a non-slip portion" (hereinafter referred to as "Prior Art 1") to correspond to a concave portion where a toe and a sole are connected And a slip prevention part protruding upwardly from the bottom surface of the sole to prevent slipping between the sole and the sole.

In the prior art 1, since the non-slip portion is formed integrally with the sole, or is slidable in the forward and backward directions, the non-slip portion is significantly different from the bend of the concave portion between the toe and the sole, There is a possibility that the non-slip portion may cause pain during walking and running. In addition, stunning stones (basal nodal bone) located in the inside of the recess between the toe and the sole are pressed, resulting in a stronger pain.

In the prior art 1, there is a problem in that the non-slippery portion generates a clearance in the front-rear direction between the toes (the recesses between the toes 10) and the slippery during walking and running, resulting in loss of propulsion.

Also, in the prior art 1, the toes come into contact with the upper surface of the sole with a flat surface, which causes a slipping phenomenon between the toe and the upper surface of the sole during walking and running, resulting in a loss of propulsion.

Also, in the prior art 1, since the toes come into contact with the upper surface of the sole having a flat surface, the feet of the shoe wearer tend to be tilted forward during walking and running, resulting in a problem of the toe wear of the shoe wearer.

In the past, a "shock absorbing insole" (hereinafter referred to as "Prior Art 2") registered in Korean Registered Utility Model No. 20-0395056 (registered on September 1, 2005.) has a position where the front end portion of the metatarsal touches the lower surface of the insole A second shock absorbing portion provided in an area including a position where the first shock absorbing portion and the heel abut on the region including the position at which the big toe comes in contact is formed to absorb and disperse the impact applied to the user's foot, And the load transmitted to the lower part is reduced to prevent various musculoskeletal disorders of the user.

However, since the first and second impact-absorbing portions are protruded from the upper surface of the insole, the impact on the front portion of the sole and the heel corresponding to the calcaneus can be alleviated, The impact on the soles and toes except for the heel is not mitigated, so that the impact reduction effect is lowered. In addition, the toes, the soles of the soles and the entire heel are not adhered to the upper surface of the insole, .

In the prior art 2, a slipping phenomenon occurs between the foot and the insole of the shoe wearer during walking and running, and the foot of the shoe wearer tends to move forward with respect to the shoe, thereby failing to solve the problems as in the prior art 1 .

In the following description, when five toes are individually described, the toes 21, the second toes 22, the third toes 23, the fourth toes 24, and the young toes 25 are described collectively In the case of describing five toe recesses formed between the distal end of the sole 10 and the toes 20, the toe recesses 31, the second toe recesses 31, The third toe recess 33, the fourth toe recess 34 and the young toe recess 35 will be described as the concave portion 30. The concave portion 30 will be described below.

4 to 11 show a preferred embodiment of a shoe outsole according to the present invention. Figures 4 to 11 show the left foot outsole.

As shown in Figs. 4 to 11, the outsole OS according to the present embodiment has an outer shape corresponding to the plane projection shape of the foot.

The outsole OS includes a foot corresponding portion 100 formed at an intermediate portion corresponding to a wearer's foot 10 and a toe portion formed at a tip portion of the foot corresponding portion 100 in correspondence with the wearer's toe 20, An urging force enhancing part 300 having an upper surface convexly formed between the foot corresponding portion 100 and the toe corresponding portion 200 in correspondence with the concave portion 30 of the wearer, And a footrest corresponding part 400 formed at the rear end of the foot corresponding part 100 in correspondence with the foot rest 40.

The outsole (OS) corresponds to the projected area of the foot and can be formed to have a large area as much as a margin for joining the upper or the band. An edge F protruding upward is provided at the edge of the outsole OS.

The foot corresponding portion 100 may be formed as a curved surface corresponding to the soles 10 of the wearer.

The toe counterpart 200 is formed to have a lower portion corresponding to the big toe 21 according to the shape of the wearer's toes 20 and to be gradually inclined upward toward the portion corresponding to the toe 25, The second toe 22, the third toe 23, the fourth toe 24 and the young toe 25 can be brought into close contact with the toe counterpart 200.

The toe 21, the second toe 22, the third toe 23, the fourth toe 24 and the young toe 25 of the wearer are both applied to the toe counterpart 200 with equal force Not only the propulsive force due to the force applied to the portion corresponding to the thumb toe 21 of the toe counterpart 200 during the "toe peeling" period of the gait cycle and the "propeller" The third toe 23, the fourth toe 24, and the young toe 25 are all used as the driving force. As a result, the driving force is increased, So that the wearer's physical power consumption can be reduced accordingly.

In addition, the toe counterpart 200 is formed to be upwardly inclined toward the front, and the back and forth shoe counterpart 400 is formed to be inclined upward toward the rear, and is elastically deformed downward when the wearer's force is applied during walking and running, When the wearer's force is extinguished, the wearer's elasticity is restored upward, thereby acting as a force for lifting the wearer's foot, thereby helping the wearer to release his / her foot. Thus, light walking and running are possible, Thereby reducing the physical power consumption of the user.

Further, since the toe counterpart 200 is formed to be inclined upward toward the front, it is possible to prevent the feet of the shoe wearer from leaning forward to the shoe during walking and running, thereby preventing the shoe of the shoe wearer from being injured.

The thrust increasing unit 300 may be formed to be convex only on the upper surface, but it is preferable that the thrust increasing unit 300 is formed so that the upper surface is convex and the lower surface is concave to reduce the weight of the outsole OS.

The thrusting force enhancing portion 300 is formed such that the height of the portion corresponding to the concave portion of the toe 31 is low and the height of the portion of the thrusting reinforcement 300 corresponding to the concave portion 35 of the wearer is low To-be-depressed portion 31 of the wearer's shoulder is formed so as to be gradually widened toward the portion corresponding to the toe recessed portion 35, so that the wearer's thumb toe recess 31, The toe recesses 32, the third toe recesses 33, the fourth toe recesses 34 and the young toe recesses 35 can all be brought into close contact with the thrust increasing unit 300.

The second toe 22, the third toe 23, the fourth toe 24, and the young toe 25 of the wearer during the "toe lifting" period of the walking cycle and the "propeller" So that the driving force can be increased. As a result, the walking and traveling speed can be increased by that much, and the wearer's physical strength can be reduced. .

The toe counterpart 200 is constructed such that the toe 21, the second toe 22, the third toe 23, the fourth toe 24 and the young toe 25 are in close contact with each other, The reinforcing portion 300 can be in contact with both of the thumb toe recess 31, the second toe recess 32, the third toe recess 33, the fourth toe recess 34 and the young toe recess 35 The young toe 25 is brought into close contact with the toe counterpart 200 even when strong force is applied to the young toe 25 according to the condition of the ground or the walking and running conditions, 35 are in close contact with the thrust increasing unit 300, the wearer loses balance and falls, and the young toe 25 or the ankle is not injured.

The shoe outsole according to the present embodiment further includes a rolling action part 500 whose upper surface is convex along a center line passing through the medial part of the foot sole support part 100 and the foot support part 400.

The rolling action portion 500 may be formed in a convex shape only on the upper surface, but it is preferable that the rolling action portion 500 is formed so that the upper surface is convex and the lower surface is concave embossed to reduce the weight of the outsole OS.

When a force is applied to the left or right side relative to the rolling operation part 500 in accordance with the condition of the ground or the walking and running conditions during walking and running, As shown in FIG.

The left half or the right half of the wearer's soles 10 and the back of the foot 40 are brought into close contact with the left half or the right half of the foot corresponding portion 100 and the back and forth shaft corresponding portion 400, The foot 10 and the footrest shaft 40 are held so as not to slide to the right or left so that the wearer does not lose balance and falls or is not injured by an ankle and does not lose his propulsion force, .

In this case, the toe 20 and the concave portion 30 are also located on the left side of the thumb toe 21, the second toe 22, the big toe concave portion 31 and the second toe concave portion 32, The toes 24, the toes 25 and the fourth toe recesses 34 and the toe recesses 35 can be brought into close contact with the left half or the right half of the thigh support portion 200 and the thrust support portion 300 Therefore, the wearer does not lose balance and falls, does not suffer an ankle injury, and there is no loss of propulsion force, so that stable walking and running are possible.

The shoe outsole according to the present embodiment can be used to scan the shape of the wearer's soles 10, toes 20, recesses 30 and feet 40 in a three-dimensional manner and scan the foot corresponding parts 100, The counterpart 200, the thrust increasing unit 300, and the weft counter shaft counterpart 400. [

Also, spike protrusions S can be formed on the bottom surface of the outsole (OS) according to the present embodiment when a soccer shoe is applied as shown in the drawing. Various types of protrusions or spikes .

The outsole (OS) according to the present embodiment further includes a plurality of buffer function parts 610 formed in the sole corresponding part 100 and a plurality of buffer function parts 620 formed in the foot corresponding part 400 (See Figs. 10 and 11).

The shock absorbing portions 610 formed on the soles corresponding to the soles 100 are formed in four pairs on the left and right sides of the soles corresponding to the soles 100 as shown in the figure, (620) may be formed as a pair of left and right, but is not limited thereto, and may be increased or decreased depending on the size of the shoe.

11 shows a cross section of the buffering action portion 610 formed on the distal end side of the plantar portion 100, it can be understood that the remaining buffering action portions 610 and 620 also have the same sectional shape.

The buffering portions 610 and 620 are concave on the upper surface and convex on the lower surface.

The cushioning portions 610 and 620 are elastically deformed downward when the wearer's force is applied to the soles corresponding portion 100 and the heel axis correspondence portion 400 during walking and running, The elastic restoring process is repeated. Through this process, the shock transmission to the wearer is minimized by buffering action.

In the meantime, at the time of fast running, the foot shaft 40 does not touch the ground first, but the front end of the foot corresponding part 100, the toe corresponding part 200 and the thrust increasing part 300 first come into contact with the ground. So that unnecessary force may be consumed.

The outsole (OS) according to the present embodiment is configured such that its center of gravity is biased toward the distal end of the foot corresponding portion 100 and the toe corresponding portion 200 side.

Accordingly, even when the wearer does not apply force to the ankle, the distal end portion of the foot corresponding portion 100, the toe corresponding portion 200, and the thrust increasing portion 300 are inclined downward, thereby consuming unnecessary force .

In order to configure the center of gravity of the outsole (OS) to be biased toward the front end of the foot corresponding portion 100 and the toe corresponding portion 200, concave / convex portions or spike protrusions formed on the bottom face are formed to correspond to the front end portion of the foot corresponding portion 100 and the toe correspondence Can be formed intensively on the substrate 200 side.
