Description

Functional Slippers

The present invention relates to functional slippers, and more specifically, to maintain correct posture alignment during the gait of a slipper wearer, which is usually prone to becoming distorted when wearing slippers, and to minimize walking energy consumption for the slipper wearer, thereby improving the walking posture while wearing slippers. It relates to functional slippers that reduce fatigue while walking, improve joint stability while walking for long periods of time, and allow the slipper wearer to easily correct the correct walking posture.

In general, slippers refer to shoes that can be easily put on and taken off without straps or special materials to cover the toes or heels. They include an instep pad that covers and protects the instep of a person's foot when worn, and the sole of the wearer's foot. It consists of a slipper sole that supports and protects, and the sole of the wearer's foot is seated on the upper side of the slipper sole, and the lower side is in contact with the ground, so it is usually manufactured by injection molding using synthetic resin materials to have a tough and cushioned feeling. there is.

Meanwhile, since the human body is connected to each other through a kinetic chain that connects the feet, knees, pelvis, and spine, foot diseases and foot deformities can cause pain and deformation of the knees, waist, and shoulders, which are various diseases of the musculoskeletal system. To prevent this, there is a need for shoes that can distribute the pressure on the feet and encourage the wearer to walk properly.

In the case of slippers, they are mainly chosen by users due to the simplicity and convenience of opening most of the foot, but slippers have a significantly poor adhesion to the foot, making walking unstable, making it difficult to move the center of pressure during walking in an ergonomic way. , If slippers are worn for a long time, incorrect walking behavior may persist, causing various foot diseases and foot deformities.

Accordingly, in Registered Patent No. 10-2252967 (title of the invention: 'Support member for flat foot treatment and functional slippers equipped with this support member), the device is configured to support the inner and outer arches of the user and to surround the rear foot. Slippers equipped with a support member are provided to support the inner and outer arches of the sole of the user's foot and to cover the rear foot, thereby preventing various physiological problems that may occur in the sole of the foot, ankle joint, knee joint, etc., which may be caused by flat feet. It is intended to relieve the condition and help treat flat feet and relieve symptoms in the long term. However, in this case, when walking for a long time while wearing slippers, it is important to control or fix the left and right shaking or twisting of the sole of the user's foot due to wearing slippers. There is a problem that walking fatigue increases due to insufficient walking, and there is a problem that it is difficult to correct the correct gait for slipper wearers.

In addition, in Registered Patent No. 10-2493347 (title of the invention: 'Functional slippers for preventing and correcting foot diseases'), walking efficiency is improved through a contact pad that closely supports the arch of the foot, but simply adheres the arch of the foot closely. There is a problem that support alone interferes with the rotation of various joint parts of the sole and increases walking fatigue, and cushioning grooves corresponding to the 1st metatarsal head, 5th metatarsal head, and midbone are formed on the bottom of the sole for walking. However, it is possible to prevent flat feet and correct the feet when walking, but the formation of the cushioning groove alone does not effectively guide the rolling movement of the sole along the path of the center of pressure when walking, so it is difficult to correct the correct gait, and it is difficult to correct the foot after using the adhesive pad. It is designed to prevent the heel from coming off the slipper and relieve shock by forming a heel cup that covers the heel. However, due to the soft cushioning of the material to cushion the heel shock, it protects the sole from the shock generated when walking. There is a problem in that it does not effectively control the left and right shaking or twisting of the sole, and there is a problem that fatigue significantly increases when walking for a long time due to an increase in muscle usage due to the left and right shaking and twisting of the sole.

It is a cross-sectional view in the width direction of the portion 24, and Figure 6 is a state diagram of the main inner and outer parts of the left slipper in the functional slipper 1 according to the invention, which briefly shows the state that appears during the gait of the slipper wearer.

As shown in FIG. 2, the functional slippers (1) according to the present invention are largely composed of a midsole (20) on which the sole of the user's feet rests, and both ends combined with the left and right sides of the midsole (20) to form a space for the user. An instep pad (10) covering the instep, an upper side coupled to the lower side of the midsole (20) to firmly support the midsole (20), and an outsole (40) whose lower side is in contact with the ground. is formed

As shown in FIGS. 2 and 3, the midsole 20 includes a toe seating portion 21 on which the sole of the user's foot is seated on the upper side, and on which five toes of the sole of the user's foot are seated on the upper side, and A forefoot seating portion 22 on which the forefoot portion below the five toes is seated, a midfoot seating portion 23 on which the midfoot portion below the forefoot portion is seated, and a rearfoot seating portion 24 on which the rearfoot portion below the midfoot portion is seated. ), and the material allows the user to feel comfortable through the soles of the feet seated on the upper side, has a cushioning feel to relieve shock while walking, and can be formed of urethane material, which is widely used as an elastic material. , It can be formed with a predetermined strength value lower than the strength value of the outsole 40, which is located on the lower side of the midsole 20 and supports the midsole 20 and the lower side touches the ground and rubs.

The instep pad 10 has both left and right ends coupled to the left and right sides of the midsole 20, respectively, and the central part, although not shown, is formed of a cushioning material with a predetermined elastic force value to provide comfort to the wearer. It may be provided with an instep compression portion that presses and adheres to one side of the upper side of the instep, and one side of the lower side of the instep compression portion adheres to one side of the upper side of the user's instep, which is seated on the midsole 20, making the user more compact. Functional slippers (1) can be worn on the feet to enable stable walking.

As shown in FIGS. 2 and 4, the upper side of the outsole 40 is tightly coupled to the lower side of the midsole 20, the lower side is in contact with the ground, and the strength of the midsole 20 By forming a predetermined strength value higher than the value, the midsole 20 located on the upper side can be firmly supported and the left and right movement and distortion of the midsole 20 during walking can be minimized. On the lower side of the outsole 40 in contact with the ground, there is a COP (Center Of Pressure) connecting the center of the rear foot of the user's sole, which is seated on the upper side of the midsole 20, and the center of the second toe located on the side of the big toe. Along the curve, a weight movement guide groove 41 of a predetermined depth is formed to a predetermined length, and the lower side of the outsole 40 is formed with the COP curve as a reference line, the inner side toward the inside of the wearer's body and the wearer's body. It is divided into an outer side facing outward, and a rear anti-slip pattern forming portion 42 is provided on the rear inner side of the lower side of the outsole 40, where the pressing force of the inside of the rear foot of the user's sole seated on the midsole 20 is transmitted, , A front anti-slip pattern forming portion 43 is formed on the front outer side of the lower side of the outsole 40, where the pressing force from the second to fifth toes of the sole of the user's foot and the outside of the forefoot, which is seated on the midsole 20, is transmitted. .

Through this, when the wearer walks, the inner portion of the rear sole of the foot is usually placed on the ground first, and at this time, the rear anti-slip pattern forming portion ( 42) touches the ground first and increases friction with the ground, allowing the wearer to step on the ground more stably. After stepping on the ground with the inside of the rear foot first, the wearer is provided on the lower side of the outsole 40. The wearer's weight naturally moves along the weight transfer guide groove 41 while being guided by the weight transfer guide groove 41, and the outsole 40 and the midsole 20 are deformed to be convex toward the ground. This happens almost simultaneously, and the wearer's weight moved along the weight transfer guide groove 41 increases friction with the ground at the front anti-slip pattern forming portion 43 on the lower side of the outsole 40, so that it moves to the front of the wearer's foot. It prevents the slipper from slipping outward from the body, prevents gait, and corrects the correct gait. In addition, the slipper wearer receives driving force from the ground through increased friction between the front anti-slip pattern forming part 43 and the ground. You will be able to walk more conveniently.

In the functional slippers 1 according to the present invention, as shown in FIGS. 1, 2, and 6, the inside of the midfoot seating portion 23 of the midsole 20 has a predetermined depth along the longitudinal direction. An inner arch supporter insertion groove 30 is formed, and an outer arch supporter insertion groove 31 is formed on the outside of the midfoot seating portion 23 of the midsole 20 at a predetermined depth along the longitudinal direction, and the midsole 20 ) is formed with a predetermined strength value higher than the strength value of, the lower part is detachably inserted and coupled to the inner arch supporter insertion groove 30, and is formed at a predetermined height and curved shape to protrude upward, with the highest protruding The inner arch supporter 32 is provided to support the navicular region of the foot at a position spaced a predetermined distance rearward from the apparently most concave portion of the inner arch of the midfoot of the user.

In addition, it is formed with a predetermined strength value higher than the strength value of the midsole 20, the lower part is detachably inserted and coupled to the outer arch supporter insertion groove 31, and is formed at a predetermined height and curved shape to protrude upward. The outer arch supporter 33 is provided so that the highest protruding portion supports the cuboid bone portion of the foot at a predetermined distance rearward from the apparently most concave portion of the outer midfoot arch of the user.

In a typical slipper sole or shoe insole, the inner arch supporter and the outer arch supporter to support the inner and outer arches of the midfoot are formed in a curved shape that protrudes at a predetermined height, and are generally the most visible in appearance of the inner and outer arches. The highest part of each arch supporter is also formed to correspond to the most concave part of the sole, which is covered with muscle and skin, so that the inner and outer arch supports adhere closely to the concave part.

In this way, when the highest part of the conventional inner and outer arch supporter is in close contact with the most concave part of the exterior of the inner and outer arch of the sole, it provides temporary comfort due to the feeling of compact support with an elastic cushion when standing still. However, when the wearer walks, the most concave part of the inner and outer arch of the sole can realize a comfortable gait through rolling deformation through natural lower side collapse without support, and as in the prior art, the inner and outer arch of the sole can be felt. The inner and outer arch supporters that adhere closely to the most concave part of the arch exterior have the problem of preventing the lower side from collapsing in the most concave part of the inner and outer arch exterior, making walking uncomfortable.

Accordingly, in the case of the functional slippers 1 according to the present invention, as shown in FIG. 6, the highest protruding portion of the inner arch supporter 32 is rearward from the apparently most concave portion of the inner arch of the midfoot of the user. In addition to supporting the navicular region of the foot at a position spaced a predetermined distance apart, the highest protruding part of the outer arch supporter 33 is spaced a predetermined distance rearward from the apparently most concave part of the outer midfoot arch of the user. By supporting the cuboid region of the foot, it is possible to correct nasolabial gait and flatfoot by supporting the navicular region where pronation usually occurs. When the wearer walks, it is supported at the most concave part of the inner and outer arch of the foot. Rolling deformation occurs due to natural lower side collapse without load, making it possible to realize a comfortable gait.

Preferably, although not shown, a plurality of the inner and outer arch supports 32 and 33 are provided so that the shape and height are the same and the strength value is gradually increased to a predetermined value, which generally prevents a slight change in strength value. By using the change in muscle response according to the sensed plantar nerve stimulation, a plurality of inner and outer arch supports equipped with the above multiple levels of intensity values are used to correct the nasolabial gait and flat feet according to the body and sole conditions of the slipper wearer. Prepare and enable them to be attached and detached.

In the functional slippers 1 according to the present invention, as shown in Figures 2 and 5, a boundary protrusion 25 is formed around the lower part of the midsole 20 to protrude downward at a predetermined length and width, A border insertion surface 44 is formed to be stepped around the upper periphery of the outsole 40, so that when the upper surface of the outsole 40 is tightly coupled to the lower side of the midsole 20, the border insertion surface 44 ) is in close contact with the inner surface of the boundary protruding surface, and the upper side of the outsole 40 is coupled to the lower side of the midsole 20, making it hard with a lower strength value than the outsole 40. The midsole 20, which has a higher cushioning feeling than the feeling, improves the fit of the user's sole, which is seated on the upper side of the midsole 20, and allows the midsole 20 to more effectively relieve the impact of the sole of the foot when walking. In addition, the outsole 40, which has a high strength value located at the bottom, can support the left and right movement of the midsole 20 during walking, which appears due to its high cushioning, causing left and right shaking or twisting of the sole. can be minimized, and muscle usage and walking fatigue can be reduced.

Preferably, as shown in Figure 4, on the lower side of the outsole 40, a plurality of auxiliary bending guide grooves 45 of a predetermined length are provided on the left and right sides of the weight transfer guide groove 41, respectively. It is provided along the weight transfer guide groove (41) at intervals, so that when the inside of the rear sole of the wearer's foot first steps on the ground through the rear anti-slip pattern forming portion (42), the plurality of auxiliary bending guide grooves (45) ), it is possible to guide the wearer's weight movement more naturally along the weight movement guide groove 41 through the quick and easy induction of bending deformation.

In addition, as shown in FIG. 4, on the lower side of the outsole 40, along the boundary between the toe seating portion 21 and the forefoot seating portion 22 of the midsole 20 located on the upper side, the outsole The weight transfer guide groove at a position corresponding to the lower side of 40 and at a position corresponding to the lower side of the outsole 40 along the boundary between the forefoot seating portion 22 and the midfoot seating portion 23. On the left and right sides of (41), main bending guide grooves (46) are formed, respectively, with a groove depth that is deeper by a predetermined depth and a groove width that is longer than the auxiliary bending guide groove (45). Simultaneously with the wearer's weight movement guided along the plurality of auxiliary bending guide grooves 45 and the weight shift guide groove 41, the outsole 40 and midsole 20 are deformed convexly toward the ground, especially the The boundary portion of the toe seating portion 21 and the forefoot seating portion 22, where the degree of deformation and bending rapidly increases, and the boundary portion of the forefoot seating portion 22 and the midfoot seating portion 23, respectively, along the auxiliary By forming the main bending guide groove 46 with a longer groove depth and width than the bending guide groove 45, the outsole 40 and midsole 20 can be bent toward the ground more quickly and sharply, and more It enables a comfortable gait and reduces fatigue caused by walking for long periods of time.

Preferably, as shown in FIGS. 2 and 5, a heel cup portion is formed concavely in the center of the rear foot seating portion 24 of the midsole 20 to surround the central portion of the rear foot of the wearer, and the midsole 20 ), a rearfoot shock-absorbing protrusion 26 is formed on the central bottom of the rearfoot seating portion 24, that is, on the bottom of the heel cup portion, to protrude downward at a predetermined height, and the rearfoot shock-absorbing protrusion 26 is located at a position corresponding to the rearfoot shock-absorbing protrusion 26. A rearfoot protrusion seating groove 47 is formed on the rear upper side of the outsole 40 so that the rearfoot shock-absorbing protrusion 26 is seated inside the groove, and the strength value is relatively lower than that of the outsole 40 at a predetermined strength value. In addition to the rearfoot seating portion 24 of the midsole 20, which has a large shock-relieving effect, the midsole 20 is further expanded downward through the configuration of the rearfoot shock-absorbing protrusion 26, which allows the wearer to walk more effectively. The ground shock transmitted through the rear foot can be significantly alleviated.

In addition, as shown in FIGS. 1, 3, and 6, the toe seating portion 21 of the midsole 20 protrudes into the space between the big toe on the sole of the wearer's foot and the second toe located on the side. A thumb that is provided with a big toe rotation guide side protrusion (27) and supports the rear part of the metatarsophalangeal joint of the foot at a position spaced a predetermined distance rearward from the apparently most concave part of the area where the big toe and the forefoot are connected on the sole of the wearer's foot. It is provided with a toe rotation support protrusion 28, and a forefoot outer support portion 29 that supports the outer side of the forefoot of the wearer's sole is connected to the big toe rotation guide side protrusion 27 in the outward direction to form the midsole 20. It may be formed to protrude in a predetermined shape so as to extend in an outward direction.

In the case of conventional slippers, a protrusion is provided to support the midfoot portion, the transverse arch portion, and the entirety, so that when the wearer is standing still, the wearer feels comfortable due to a cushioned feeling that is closely supported by the midfoot portion or the transverse arch portion by the protrusion. In the case of the present invention, the rear portion of the metatarsophalangeal joint of the foot at a position spaced a predetermined distance rearward from the apparent most concave portion of the portion where the big toe and forefoot of the sole of the wearer are connected, rather than the midfoot portion or transverse arch portion, is the thumb. By supporting the toe rotation support protrusion (28), nerve stimulation is provided to the rear portion of the metatarsophalangeal joint where rotation of the big toe occurs, and the big toe is supported by the big toe rotation support side protrusion (27). While receiving guidance in contact with the side, it is possible to naturally rotate downward without the rotation being hindered by conventional simple close support, and the downward rotation of the big toe naturally induces the lifting of the heel, thereby increasing the wearer's walking energy when walking. Use can be reduced and walking fatigue can be reduced.

In this way, the functional slipper (1) according to the present invention supports the inner and outer arches of the sole and helps the major joints of the sole to rotate smoothly while walking for a comfortable gait or allows for free rotation. By doing this, walking fatigue can be minimized, and the movement of the soles of the feet during walking can be guided more effectively along the path of the center of pressure to correct the correct gait.

In addition, it is possible to reduce muscle usage and walking fatigue by alleviating the impact of the heel while walking and minimizing the left and right shaking or twisting of the sole.

Although several embodiments have been described above as examples, it is obvious to those skilled in the art that the present invention can be embodied in various other forms without departing from the spirit and scope thereof.

Accordingly, the above-described embodiments are to be regarded as illustrative rather than restrictive, and all embodiments within the appended claims and their equivalents are intended to be included within the scope of the present invention.
