Description

SUPPORT FOR ANKLE TO BE FIXED TO FOOTWEAR, AND FOOTWEAR EQUIPPED WITH IT TECHNICAL FIELD The present invention relates generally to an ankle support, fixed to the footwear and, more particularly, to an ankle support which is fixed to the sole on the inside of the footwear and which is used to encircle a portion of the leg that It is on top of the ankle joint. Additionally, the present invention relates to footwear having that ankle support.

ANTECEDENTS OF THE TECHNIQUE In general, the footwear has a sole, a cut and a heel section. Footwear is typically classified in a shoe whose heel section does not extend above the ankle joint, and a boot whose heel section extends above the ankle joint. The boots are suitable for a user who must work in relatively inhospitable environments. Boots include work footwear, safety footwear, military footwear, etc. In this case, work shoes or safety shoes only need to prevent foreign objects from coming into contact with the user's leg or entering the inside of the footwear. In that way, work shoes or safety shoes are used to loosely surround the user's leg. On the other hand, military footwear, or similar ones, must prevent a user from being damaged; for example, to prevent the user's ankle from suffering a sprain due to excessive twisting, rotation or bending of a portion of the leg and a portion of the foot, between which the ankle joint is located, when the user is active with the shoes on. Thus, military footwear, or its like, is used to remain in intimate contact with the user's leg. The boot has many advantages; that is, it prevents foreign objects from entering the boot, as well as preventing the user from being damaged. However, the boot has the disadvantage that it prevents the natural movement of the foot or the ankle joint. Therefore, for footwear in general or athletic footwear, the shoe is preferable to the boot. The shoe allows the user to move quickly. However, the shoe has no means to prevent the foot or ankle joint from twisting, turning or flexing excessively. Accordingly, the boot is preferred as athletic footwear for activities that do not require much natural movement of the ankle joint, especially riding boots. However, in cases where it is necessary to allow active movement and prevent damage to the ankle joint, as in basketball shoes, a middle term is used between the shoe and the boot, that is, the booties. However, shoes such as athletic footwear should be used inevitably for sports that require a lot of activity, such as shoes for soccer or baseball. Thus, the user is always exposed to the danger of injury. Taking into account the activity, attempts have been made to develop athletic shoes in the style of booties. For example, the application for Korean utility model No. 1 998-5838 and the application for Korean utility model No. 2003-16830 have proposed it. Utility model application No. 1998-5838 was filed by the inventor of the present invention and is entitled "Athletic footwear having improved safety and life expectancy" (Athletic Footwear having improved safety and Ufe span). Additionally, the application for industrial model No. 2003-16830 was filed by the inventor of the present invention and has the title "Athletic shoes having ankle protector" (Athletic footwear having ankle protector). In addition, booty-style athletic shoes have been proposed in the Japanese utility model publication open to public inspection No. Sho 57-34804, which is entitled "Athletic footwear," in US Pat. No. 5, 430,960 entitled "Light weight athletic shoe with foot and ankle support systems" (Lightweight athletic shoe with foot and ankle support systems), and in U.S. Patent No. 5,943,793, entitled "Shoe or boot with adjustable ankle collar" (Shoe or boot with adjustable collar ankle). The booty athletic footwear, mentioned above, includes a protective ankle portion, which extends from an upper end of an ankle section to a leg portion, above the wearer's ankle joint, and is used to Surround the leg portion that is on top of the ankle joint. While conventional booty style athletic shoes are provided with various means to provide the user with unrestricted movement, booty-style athletic shoes, different from basketball shoes, do not satisfy consumers. In order to reduce the danger of damage, an ankle protector illustrated in Figure 1 has been placed on the market. Many athletes often wear the shoes that have ankle protector on. However, the ankle protector 100 merely surrounds a leg portion extending from the heel of the foot to a portion above the ankle joint. That is, the ankle protector 100 is separated from the footwear, so that the ankle protector 100 can move irrestrictively relative to the footwear. Therefore, even if a person wears the ankle protector 100, the user's ankle joint may be twisted, turned or bent excessively due to the force exerted on the footwear. Additionally the application of Korean utility model No. 1969-5433 describes an ankle protector that is attached to the footwear and is used with it, which is entitled "Athletic footwear with removable ankle protector" (Athletic Footwear with detachable protective ankle). The conventional ankle protector is configured so that it is attached to an upper end of the heel section of a shoe, using a zipper closure. When the ankle protector is attached to the shoe, the shoe assumes the shape of a conventional, booty-style athletic shoe.

BETTER WAY In the following, an ankle support and footwear with the ankle support will be described according to the preferred embodiment of the invention, with reference to the accompanying drawings. Figure 2 is a perspective view of an ankle support to be affixed to a footwear, according to an embodiment of the present invention. Fig. 3 is a perspective view schematically showing the state in which a user's foot fits within the ankle support of Fig. 2, and Fig. 4 is a developing view of the ankle support of Fig. 3. shown in Figures 2 to 4, the ankle support 200 of this invention is configured so that the ankle support 200 is fixed to a sole, in the interior of a general purpose shoe that does not extend above the ankle. , and extends upwardly from a heel section of the shoe to encircle a leg portion above the ankle joint. That is, the ankle support 200 is fixed to the sole (eg, a top surface of a midsole) on the inside of the shoe. Thus, a fastening device 210 is provided in a lower portion of the ankle support 200, for securing the ankle support 200 to the sole inside the footwear. The fixing means 210 can have any shape, as long as the fixing means 210 fixes the ankle support 200 to the sole. It is preferred that it additionally include an additional fastening member, such as a Sailboat lock. In this case, part of the fastening means 21 0 may be open. Alternatively, the fixing means 210 can be completely closed. Figure 2 shows the fixing means 210 which is partially open. Additionally the ankle support 200 is provided with an ankle support part 220. The fixing means 210 is fixed to the sole, inside the footwear, while the ankle-supporting part 220 extends upwards from the heel section, to surround part of the foot and part of the leg, between which is located the joint of the user's ankle, thus supporting the ankle. The botle supporting part 220 includes a means covering the leg and a supporting means. In this case, the means covering the leg is configured to surround a portion of the leg that lies above the user's ankle joint. The supporting means is provided between the means covering the leg and the fixing means 210, thereby preventing the user's foot from moving around the ankle joint beyond a predetermined range. A hole 221 for insertion of the foot is formed at an upper end of the ankle support portion 220, and allows the user's foot to be inserted within the ankle support portion 220. In addition, an opening 222 is provided in a predetermined position in the ankle support portion 220, so that the user's foot can be conveniently inserted within the ankle support portion 220. In this case, the ankle support part 220 can be made of a kind of material having an individual structure. Alternatively, the ankle support portion 220 may be made of different kinds of materials. In this case, different parts are stitched together to provide the ankle support part 200. The ankle support portion 220 also includes a squeezing unit that closes the opening 222 provided in a predetermined position of the ankle support portion 220, thereby allowing the ankle support 200 to be in tight contact with the wearer's ankle. The pressing unit may comprise a plurality of eyes that are formed on both sides of the ankle support part 220, and a general shoelace that ties the shoe. In addition, the pressing unit may comprise a closure Sailboat that is provided on both sides of the ankle-supporting part 220. Additionally, the squeezing unit may comprise a sliding closure that is stitched along both side ends of the ankle support portion 220. The squeezing unit may also comprise a strap having a buckle and a hole punched in respective sides of the ankle support part 220. The pressing unit may comprise a combination of the elements mentioned above. When the ankle support 200 of this invention is adapted to general purpose footwear, the ankle support part 220 is preferably configured to prevent foreign objects from entering the interior of the shoe, through the opening 222. Thus, it is preferable that the ankle support part 220 additionally includes a tongue (not shown). The tongue is secured at one of its ends to an inner surface of the ankle-supporting portion 220, and is long enough to cover the opening 222. Preferably the tongue of the ankle-bearing portion 220 is made in such a way that the part bottom of the tongue overlaps part of the tongue of the footwear. In addition, an additional member may be provided on the tongue of the ankle support portion 220, to be attached to the tongue of the general purpose footwear. Additionally, the ankle support part 220 can be constructed to be larger than the user's ankle size, in order to prevent foreign objects from entering the footwear. In other words, if the ankle support portion 220, adapted to the general purpose footwear, is larger than the user's ankle, the user's ankle can be completely covered by overlapping both sides of the ankle support part 220. On the other hand, the ankle support 200 of this invention can be constructed in such a way that the ankle support 200 is closed without the opening 222. In this case, part of the ankle support part 220 can consist of an elastic member that it has elasticity, or the entire part of the ankle-supporting part 220 may consist of an elastic member. In such a manner, the ankle support 200 of this invention is constructed so that the lower portion of the ankle support 200 is fixed to the interior of the shoe, contrary to the prior art.; thus moving with respect to the footwear, within a predetermined range. Therefore, the footwear having the ankle support 200 of this invention moves together with the ankle support 200 without restricting the movement of the user's ankle joint in the footwear; thus guaranteeing the flexible movement of the ankle; so it allows its unrestricted movement. In addition, the footwear having the ankle support 200 of this invention is constructed so that the lower portion of the ankle support 200 is secured to the interior of the shoe. D? that way, even when shocks are applied to the user's ankle due to intense activity, the user's ankle is protected by both the footwear and the ankle support 200; thus allowing the user's ankle to be protected efficiently. The preferred embodiment of the ankle support according to this invention will now be described in detail. As shown in Figures 2 to 4, the ankle support 200 of this invention is made of different kinds of materials. These parts are sewn to be combined with each other. The tightening unit includes eyes and laces. In a detailed description, the foot insertion hole 221 and the opening 222 are formed in the upper part and the front of the ankle support part 220, respectively. The ankle supporting part 220 includes the means covering the leg and the supporting means. The medium that covers the leg surrounds a portion - of leg, above the ankle joint, and the supporting means prevents the user's foot from moving around the joint beyond a predetermined range. The leg covering means includes a strap 224 that is coupled to the upper end of the support means, and surrounds the leg portion above the user's ankle joint. In addition, the support means includes a ventilation portion 223, and a reinforcement strip. Ventilation part 223 is provided in a position around the bead section, to allow air to flow to and from the shoe. The reinforcement strip works to partially strengthen the user's ankle. The ventilation part 223 dissipates the heat generated in the footwear, when a person moves or exercises with the shoes on, in addition to allowing fresh outside air to circulate in the footwear. The ventilation part 223 is made of a soft material that allows ventilation. It is preferred that the ventilation part 223 extends upwardly from a lower end to a predetermined height. Additionally, the reinforcement strip comprises a first strip portion 225, a second strip portion 226 and a third strip portion 227. The first strip portion 225 is disposed along the user's Achilles tendon to engage the strip 224 of the medium covering the leg with the fixing means 210. The second strip part 226 is located in the internal malleolus of the user, for coupling the strip 224 to the fixing means 210. Additionally, the third strip part 227 is located in the outer malleolus of the user for coupling the strip 224 to the fixing means 210. In this case the reinforcing strip can have at least one of each first, second, third strip portions 225, 226, 227. The reinforcing strip serves as a tape to massage the muscular nerves, in order to prevent the muscular nerves of the foot from relaxing or contracting abruptly before a person exercises. Said reinforcing strip is preferably made of the same hard material as the footwear, such as leather. When the strip 224 and the first, second and third strip portions 225 226 and 227 are developed, they take the form of an "m". In that way, the ankle support 220 surrounds and supports the user's ankle and efficiently protects the ankle joint, joining the ankle to the foot, and various ligaments, including the Achilles tendon, using the elements that constitute the reinforcing strip. On the other hand, the ankle support portion 220 has a plurality of folding portions 228, which fold naturally when the wearer's ankle flexes forward, thereby increasing the range of motion of the wearer's ankle. That is, the ankle bearing portion 220 is constructed so that its two sides are unequal, thus forming a plurality of folding portions 228. In addition, the squeezing portions 229 are provided at an upper end of the ankle-supporting portion 220. to project upwards, thus efficiently holding the ankle support 200 to the user's ankle. The squeezing portions 229 are connected to both ends of the strip 224. In addition, a plurality of eyes 230 are formed in the ankle support portion 220, with a rim 325 passing through the eyes 230, to connect the two sides of each other. the opening 222. The footwear with the ankle support according to this invention will be described below with reference to soccer shoes. However, this invention is not limited to shoes for soccer, but it is applicable to various shoes, such as athletic shoes for various sports, including soccer, basketball, tennis, baseball, rugby, badminton, skating, volleyball, etc.; work footwear, safety footwear, mountain climbing shoes or military footwear. That is to sayWhen the ankle support of this invention is adapted to shoes that do not extend above the user's ankle, it is necessary to adjust the height of the shoe. On the other hand, when the ankle support of this invention is adapted to boots that extend above the wearer's ankle, the ankle support is inserted into the boot, after lowering the height of the boot below the ankle. Figure 5 is a perspective view showing a soccer shoe, to which an ankle support of this invention is adapted, with part of the soccer shoe still untied. Fig. 6 is a perspective view showing the soccer shoe of Fig. 5, in which the soccer shoe is completely tied, and Fig. 7 is a sectional view, taken along line AA of Fig. 6, showing part of the soccer shoe. As shown in Figures 5 to 7, the soccer shoe 300 includes a sole 310, a cut 320 and a heel section 340, the ankle support being fixed to the soccer shoe 300.

The sole 310 includes an outer sole 31 1 in which a plurality of anti-slip pads 312 are formed. In addition, a midsole 313 is provided on the outsole 31 1, to be integrated with the outsole 31 1. The cut 320 includes a tip 321 to cover the user's fingers, a first blade 322 to cover the inner portion of the upper side of the foot, a second blade 323 to cover the outer portion of the upper side of the foot, and a tongue 330. tongue 330 is connected at one of its ends to the tip 321 and covers the upper side of the foot. Additionally, the cut 320 includes a blade-tightening unit that pulls on the side ends of the first and second blades 322 and 323, so that the side end of the first blade 322 approaches the side end of the second blade 323. In this case, the blade-engaging unit includes a plurality of eyes and a rim 325. The eyes are formed in eye lugs 326, which are provided at the lateral ends of the first and second blades 322 and 323. The rim 325 passes through the eyes. However, the blade-pulling unit is not limited to the structure mentioned above. The blade shovel unit can be manufactured as the ankle support squeezing unit. The ankle support 200 is manufactured as described above. That is, the ankle support 200 is constructed so that the lower portion of the ankle support 200 is secured to the sole on the inside of the soccer shoe, and the ankle support 200 extends upwardly along the section of ankle 340 to surround part of the foot and part of the leg, enters which is the joint of the user's ankle. The soccer shoe 300 of FIGS. 5 to 7 is provided with the ankle support 200, constructed as shown in FIGS. 2 to 4. However, the fixing means 210 provided in the lower portion of the ankle support 200 is fixed between the outer sole 31 1 and the midsole 313. That is to say, the ankle support 200 is constructed so that the means covering the leg is cut in a position that goes from the upper side of the foot to the shin. In the cut position, both ends of the medium covering the leg are pulled to approximate each other using the squeezing unit. The fixing means 210 of the ankle support 200 can be fixed to the bead section 340, the first blade 322 or the second blade 323. In accordance with this invention, the first end of the cut-off means covering the leg can be connected continuously to the lateral end of the first blade 322, and the second end of the cut-off means covering the leg can be connected continuously to the lateral end of the second blade 323. The Figure 8 is a developing figure showing a tab of the soccer shoe of Figure 5. As shown in Figure 8, the tongue 330 serves to prevent foreign objects from entering the interior of the shoe. The tongue 330 is sewn on one of its ends to the inner surface of a slot 324 and covers the slot 324 and the opening 222 of the ankle support 200. The tongue 330 includes a portion 331 covering the slot, a portion 332 covering the opening, and a strap securing portion 333.
