Description

Shoes with toe stretching bands for hallux valgus and varus

[0001] The present invention relates to a toe stretching band for hallux valgus and varus minora for simultaneously pulling and stretching the toes inward and outward for hallux valgus or varus minora, and a shoe including the same.

[0002] The feet have long been considered a microcosm of the human body, reflecting the state of one's health. Furthermore, they can be considered a second heart. This is because the feet, subjected to stretching and compression, are where blood reaches the heart and is returned to the body. Therefore, if we neglect walking or develop foot problems that prevent us from walking properly, the movement of these "second hearts" (feet) decreases, impairing blood circulation. Consequently, their ability to deliver nutrients and eliminate waste products from the body is impaired.

[0003] Structural defects in the feet, such as deformities in the shape of the foot, can affect joints throughout the body, including the knees and spine, causing pain and deformities. However, with the recent widespread use of narrow, pointed-toe shoes, high heels, and platform shoes, the shape of the feet has become distorted, leading to a growing number of patients developing hallux valgus (bunions), a foot deformity that prevents the big toe, which is supposed to support and propel the foot, from functioning properly.

[0004] If this hallux valgus worsens, pain can occur in other parts of the foot. An example is hallux valgus, where the little toe (little toe) bends toward the big toe. Initially, it does not cause any particular problems other than the little toe joint protruding, but if the symptom persists, the protruding area becomes red and swollen, causing pain, and calluses and blisters may appear. If hallux valgus and hallux valgus worsen, the abnormal symptoms in the toes can cause walking difficulties, which can have a negative impact on the knees, pelvis, and spine.

[0005] Korean Utility Model Publication No. 20-2017-0000684 discloses a toe corrector that connects a big toe and a little toe fixing ring with a connecting pad, and Korean Patent No. 10-1454607 discloses a toe corrector that positions each toe by positioning a correction plate between the toes and connecting the correction plates with a bottom plate. However, toe correctors do not have a function to pull the bent big toe and little toe outward to stretch them, and they only spread the toes apart, making it difficult to secure the effect of returning the toes to their normal state.

[0006] The present invention has been devised to solve the above-described problems, and its purpose is to have the effect of stretching the toes to a normal shape while simultaneously preventing the knees from being internally rotated by simultaneously pulling the big toe inward and the little toe outward by the connected tightening surfaces while the big toe and little toe are respectively inserted and fixed in the two fixing surfaces of the toe correction band when wearing a shoe, thereby. The present invention is not limited to the technical problem described above, and other technical problems may be derived from the following description.

[0007] In order to achieve the above object, the present invention provides a toe stretching band for hallux valgus and varus, comprising: a first band (230) having a thumb band (210) formed at one end into which a thumb (50) is fitted; a second band (240) having a thumb band (220) formed at one end into which a thumb (60) is fitted; and a fixing member connecting the other ends of the first band (230) and the second band (240) while controlling tension; wherein the thumb (50) is pulled inward (10) and the thumb (60) is simultaneously pulled outward (20) to stretch the thumb.

[0008] Additionally, the fastener is one of a snap button (250a), a buckle (250b), a Velcro, and a shoelace.

[0009] Additionally, the first and second bands (230, 240) include at least one of fabric, leather, and synthetic resin.

[0010] The purpose of the present invention as described above is to provide a shoe (100) having a first instep (120) connected to a sole (110); a first insertion hole (70) formed through an area of ​​the sole (110) adjacent to a plain (50); a second insertion hole (75) formed through an area of ​​the sole (110) adjacent to a sole (60); a first band (230) having a plain band (210) formed at one end into which the plain (50) is fitted, and passing through the first insertion hole (70); a second band (240) having a sole band (220) formed at one end into which the sole (60) is fitted, and passing through the second insertion hole (75); And while controlling the tension, the first band (230) and the second band (240) are connected to each other, and the toe stretching band for hallux valgus and varus minor is characterized by pulling the thumb (50) inward (10) and simultaneously pulling the little finger (60) in the outward (20) to stretch it.

[0011] The purpose of the present invention as described above is to provide a shoe (100) having a first instep (120) connected to a sole (110); a first insertion hole (70) formed through an area of ​​the sole (110) adjacent to the plain (50); a third insertion hole (80) formed through an area of ​​the first instep (120) adjacent to the plain (50); a second insertion hole (75) formed through an area of ​​the sole (110) adjacent to the small (60); a fourth insertion hole (85) formed through an area of ​​the first instep (120) adjacent to the small (60); a first band (230) sequentially penetrating the first insertion hole (70), the third insertion hole (80), the fourth insertion hole (85) and the second insertion hole (75); A shoe including a toe stretching band for hallux valgus and varus minor, characterized in that the first band (230) includes a fixing member connecting both ends of the first band (230) while controlling the tension, wherein the first band (230) has a middle region that wraps around the thumb (50) to form a thumb band (210), and another middle region wraps around the thumb (60) to form a thumb band (220), thereby pulling the thumb (50) inward (10) and simultaneously pulling the thumb (60) outward (20) to stretch it, can also be achieved.

[0012] Additionally, the fastener is one of a snap button (250a), a buckle (250b), a Velcro, and a shoelace.

[0013] Additionally, the first and second bands (230, 240) include at least one of fabric, leather, and synthetic resin.

[0014] According to the embodiment of the present invention, a shoe including a toe stretching band for hallux valgus and varus minora having the above-described configuration has the following advantages.

[0015] When wearing shoes, the thumb and little toe are inserted and fixed into the loops on both sides of the toe correction band and pulled by the connected tightening surface, so that the thumb is pulled inward and the little toe is pulled outward, which has the effect of stretching the toes to a normal shape and preventing the knees from being rotated internally.

[0016] In addition, the length of the tightening surface can be adjusted to control the force applied outward to the thumb and little toes according to the user's foot shape, allowing for customized use for each user, maximizing the stretching effect and improving user satisfaction.

[0017] Additionally, by pulling the ligaments of the toes that have become stiff and bent due to hallux valgus or bunions, you can prevent the entire foot and shin from overpronating by making them more flexible.

[0018] However, the effects that can be obtained from the present invention are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily practice the present invention. However, the description of the present invention is merely an embodiment for structural and functional explanation, and therefore the scope of the present invention should not be construed as being limited by the embodiments described in the text. That is, since the embodiments can be modified in various ways and can have various forms, the scope of the present invention should be understood to include equivalents that can realize the technical idea. In addition, the purposes or effects presented in the present invention do not mean that a specific embodiment must include all of them or only such effects, and therefore the scope of the present invention should not be construed as being limited thereby.

[0028] The meanings of terms described in the present invention should be understood as follows.

[0029] Terms such as "first" and "second" are intended to distinguish one component from another, and the scope of the rights should not be limited by these terms. For example, a first component could be referred to as a second component, and similarly, a second component could also be referred to as a first component. When a component is referred to as being "connected" to another component, it should be understood that this may involve a direct connection to that other component, or that there may be other components in between. Conversely, when a component is referred to as being "directly connected" to another component, this should be understood to mean that there are no other components in between. Furthermore, other expressions describing relationships between components, such as "between" and "immediately between," or "adjacent to" and "directly adjacent to," should be interpreted similarly.

[0030] Singular expressions should be understood to include plural expressions unless the context clearly indicates otherwise, and terms such as "comprises" or "has" should be understood to specify the presence of stated features, numbers, steps, operations, components, parts, or combinations thereof, but not to exclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0031] Unless otherwise defined, all terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this invention pertains. Terms defined in commonly used dictionaries should be interpreted to be consistent with their meaning within the context of the relevant technology, and should not be interpreted as having ideal or overly formal meanings unless explicitly defined herein.

[0032] People with knee pain commonly have a bent big toe. The primary cause of this outwardly deformed big toe is overpronation, which means the foot rolls inward excessively. Due to the structure of the lower extremities, overpronation causes the knee to rotate inward, causing the cartilage to wear out, and this can cause knee damage more quickly than in other people.

[0033] In order to solve these problems, the present invention can provide a shoe-mounted toe correction band that has the effect of stretching the toes to a normal shape while simultaneously preventing the knees from being internally rotated by having the thumb and little toes pulled outward by the connected tightening surface while the thumb and little toes are respectively inserted and fixed in the rings on both sides of the toe correction band when wearing shoes, thereby preventing the knees from being internally rotated.

[0034] Example 1

[0035] FIG. 1 is a schematic diagram of a shoe-mounted toe correction band (200a) according to a first embodiment of the present invention, FIG. 2 is a perspective view showing a separated state of the toe correction band (200a) of FIG. 1, FIG. 3 is a front view showing a shoe-mounted toe correction band (200a) according to the first embodiment of the present invention in a state mounted on a shoe, and FIG. 4 is a partial plan view of FIG. 3.

[0036] Referring to FIGS. 1 to 4, the shoe-mounted toe correction band (200a) of the present invention may include a shoe (100) worn by a user and a toe correction band (200a) mounted on the shoe (100) to pull the user's toes to both sides and stretch them. The toe correction band (200a) may be installed and used on various types of shoes (100), such as slippers, sandals, sneakers, and dress shoes, and there are no restrictions on the shape of the shoe as long as it has a structure that covers the instep.

[0037] As illustrated in FIGS. 1 to 4, the shoe (100) is configured to allow the user to stretch the thumb (50) and the small toe (60) while wearing the shoe. In this way, the shoe (100) is equipped with a sole (110) that supports the sole of the user's foot, a first instep hook (120) that is connected to both upper sides of the sole (110) and wraps around the instep, and first and second insertion holes (70, 75) that penetrate from the side surface of the sole (110) to the upper surface of the sole (110). The first instep hook (120) may be formed in an integrated band shape so that the toe correction band (200a) can be fixed in a completely close state.

[0038] In addition, the shoe (100) may further include a second instep (140) formed approximately 30 mm apart from the first instep (120) depending on the shape and structure and arranged in one or more rows. At this time, as illustrated in FIG. 4, the second instep (140) may be formed as an integral part or may be formed of any one of a buckle, a snap button, and Velcro. The second instep (140) may be formed to tighten the user's metatarsal area, thereby anatomically spreading the toes apart to maximize the stretching effect.

[0039] That is, the second instep (140) may be provided with a structure that allows for length adjustment so that the metatarsal portion can be tightened according to the size of the user's foot or the degree of deformation of the toes. Such shoes (100) may be slippers or sandals with open toes so that the user can easily put them on while looking at them with the naked eye.

[0040] The shoe (100) is equipped so that a toe correction band (200a) can be inserted and mounted through the first and second insertion holes (70, 75). In addition, the first and second insertion holes (70, 75) may be formed with square holes extending on both sides of an oval shape so that the toe correction band (200a) can be easily inserted and mounted or removed by the user. At this time, the first and second insertion holes (70, 75) can be designed so that the user can easily insert or remove the toe correction band (200) by inserting the user's fingers.

[0041] The toe correction band (200a) is configured to stretch the thumb (50) by pulling it inward (10) and the little finger (60) by pulling it outward (20). The toe correction band (200a) may be formed in the form of a long band as illustrated in FIGS. 1 and 2. The toe correction band (200a) is configured to be inserted from the inside to the outside of the shoe (100) through the first and second insertion holes (70, 75) of the shoe (100) as illustrated in FIG. 3, and to wrap around and tighten the upper surface of the first instep hanger (120).

[0042] At one end of the first band (230), a plain band (210) is formed into which a plain (50) is fitted, and at the other end, a female snap button (250a), which is an example of a fixed body, is formed, which is a free end. At one end of the second band (240), a small band (220) is formed into which a small (60) is fitted, and at the other end, a male snap button (250a), which is an example of a fixed body, is formed, which is a free end.

[0043] The snap button (250a) can be mutually fastened / unfastened, thereby adjusting the longitudinal tension. Other fasteners may be Velcro or shoelaces, and in the present embodiment, a plurality of snap buttons (250a) are provided along the longitudinal direction of the band. The tension can be adjusted by adjusting the fastening position of the snap button (250a). In other words, the length can be adjusted according to the width of the user's instep or the stretching intensity.

[0044] The toe correction band (200a) can be made of fabric or spandex in the form of a belt or string, can be made of natural materials such as rubber or leather, synthetic resin materials such as silicone or urethane, and optionally can be made of a mixture of these.

[0045] In this way, the toe correction band (200a) can help to restore the foot shape to a normal shape by stretching the muscles that have been hardened by stretching and making them flexible by adjusting the pulling force of the thumb (50) and the small toe (60) according to the shape of the user's foot, thereby maximizing the stretching effect and improving user satisfaction by allowing customized use for each user.

[0046] Example 2

[0047] FIG. 5 is a configuration diagram of a shoe-mounted toe correction band (200b) according to a second embodiment of the present invention, FIG. 6 is a perspective view showing a separated state of the toe correction band (200b) of FIG. 5, and FIG. 7 is a front view showing a shoe-mounted toe correction band (200b) according to a second embodiment of the present invention in a state of being mounted on a shoe.

[0048] Descriptions of the same components as those of the first embodiment among the components of the second embodiment will be omitted as they are replaced with the first embodiment. As illustrated in FIGS. 5 to 7, a buckle (250b) is used as an example of a fixture. A number of holes for length adjustment are formed at the end of the first band (230), and a buckle (250b) is provided at the end of the second band (240). By varying the positions at which the buckle (250b) is inserted into the holes, the length of the correction band (200b) can be adjusted.

[0049] The shoe-mounted toe correction band (200b) according to the second embodiment is fixed by being pulled while the thumb and thumb bands (210 and 220) of the toe correction band are inserted into each other when the shoe is worn.

[0050] Additionally, by pulling the ligaments of the toes that have become stiff and bent due to hallux valgus or bunions, you can prevent the entire foot and shin from overpronating by making them more flexible.

[0051] Example 3

[0052] Fig. 8 is a front view showing a shoe-mounted toe correction band (200c) according to a third embodiment of the present invention mounted on a shoe. As illustrated in Fig. 8, a first insertion hole (70) is formed through a side area adjacent to the plain sole (50) of the sole (110).

[0053] The second insertion hole (75) is formed through a side area adjacent to the sole (60) of the sole (110).

[0054] The third insertion hole (80) is formed through the area adjacent to the thumb (50) of the first instep (120).

[0055] The fourth insertion hole (85) is formed through the area adjacent to the small part (60) of the first instep (120).

[0056] The first band (230) passes through the first insertion hole (70) from the outside, then passes through the third insertion hole (80) from the inside of the first instep (120) and is exposed to the outside. Then, it passes through the first instep (120) from the outside, passes through the fourth insertion hole (85), and then passes through the second insertion hole (75) from the inside of the first instep (120) sequentially. Optionally, the first band (230) may be placed so that one end sequentially passes through the third insertion hole (80) and the first insertion hole (70) and the other end sequentially passes through the fourth insertion hole (85) and the second insertion hole (75) after the middle part of the first band (230) is placed on the first instep (120).

[0057] A snap button (250a) or a buckle (250b) connects both ends of the first band (230).

[0058] The first band (230) has a middle region that wraps around the thumb (50) to form a thumb band (210), and another middle region that wraps around the little finger (60) to form a little finger band (220). These thumb bands (210) and little finger bands (220) wrap around approximately 3 / 4 of the circumference of the toes. This allows the thumb (50) to be pulled inward (10) while simultaneously pulling the little finger (60) outward (20) to stretch it.

[0059] Although the present invention is directed to the thumb and toes, it is of course possible to apply the same configuration and principles to other toes.

[0060] Those skilled in the art will appreciate that variations and modifications can be made without departing from the essential characteristics of the present invention. Therefore, the disclosed embodiments should be considered illustrative rather than restrictive. The scope of the present invention is defined by the claims, not the foregoing description, and all differences within the scope equivalent thereto should be construed as encompassed by the present invention.

[0061] The present invention relates to a shoe that includes a toe stretching band for hallux valgus and varus minor, effectively correcting the toes and preventing internal rotation of the knee. The toe stretching band pulls the hallux and minor to normalize their shape, and the length of the tightening surface can be adjusted for a customized fit. This not only helps prevent hallux valgus and varus minor, but also prevents overpronation of the foot and shin.
