Description

  The present invention relates to an ankle joint strengthening training device, and in particular, it is attached to an ankle joint of a foot part, and strengthens dorsiflexion force to bring a toe close to the lower leg part and trains, thereby improving walking stability. The present invention relates to an ankle joint reinforcement training tool that can be obtained and used for treatment and prevention of ankle sprains and the like.

  Conventionally, ankle joints have been used to prevent ankle sprains that occur during exercise or to use a supporter made of a stretchable cloth member for the treatment of sprains. The movement of the ankle joint is fixed by wrapping the tape around the tape. These supporters or the like regulate the movement of the ankle joint by mounting or winding it around the target ankle joint. Accordingly, even when a force is applied to the ankle joint from an unreasonable direction, it is possible to resist the force applied by the supporter and the like, and the ankle joint is protected. Therefore, the possibility of sprains during exercise can be reduced.

  On the other hand, even after a sprain has occurred, by controlling the movement of the ankle joint with the supporter, the occurrence of pain is suppressed and early improvement of symptoms is achieved. In this case, in order to completely fix the ankle joint, there is also a dorsiflexion movement that moves the toes closer to the crus around the ankle, or a sole flexion movement that moves the toes away from the crus. It is regulated similarly. That is, it is almost impossible to move the tip of the ankle.

  The above prior art is publicly practiced by those skilled in the art, and the applicant has no particular knowledge of the literature describing such prior art at the time of filing this application.

  The above-mentioned supporters and the like are intended for the prevention and treatment of sprains, but the functions of the supporters and the like have merely restricted the movement of the ankle joint. That is, sprains often occur when a strong force is applied to the ankle from the outside or the inside. When treating this sprain, only movement in that direction (outside or inside) is restricted. It was good. However, conventional supporters and the like also regulate movement of the ankle joint in the dorsiflexion and bottom flexion directions, which originally do not need to be regulated. In this case, a user wearing the supporter usually In other words, it became difficult to walk.

  In addition, the above-described supporters and the like did not reinforce the original dorsiflexion, plantar flexion, and other forces of the ankle joint. As a result of intensive studies, the applicant of the present application has found that failures such as sprains on the ankle joint can be prevented by forging a force in the dorsiflexion direction of the ankle joint (dorsiflexion force). For this reason, by constantly strengthening the dorsiflexion force of the ankle joint from the daily life, it is possible to suppress the occurrence of failures such as sprains. Furthermore, the strengthening of the dorsiflexion force can stabilize the daily walking motion. In other words, the movement of the ankle in the lateral direction with respect to the walking direction (shake) significantly impairs the stability of the walking motion. Therefore, even an elderly person with weakened muscle strength of the foot can perform a stable walking motion without wobbling by strengthening the dorsiflexion force.

  Therefore, in view of the above circumstances, the present invention can stabilize the walking motion by strengthening the dorsiflexion force, and can perform the dorsiflexion and bottom flexion movements of the ankle joint applicable to the treatment of sprains and treatment. An object of the present invention is to provide an ankle joint strengthening training tool that can be used and that regulates swinging of the ankle in the outer and inner directions.

  In order to solve the above-mentioned problems, the ankle joint strengthening training tool of the present invention includes: a belt-like crus fixing band that is wound around and fixed to the crus, and the sole of the foot from the outside of the crus Until it reaches the inside position of the crus part of the crus fixing band, and extends and contracts to contact the ankle side surface and the sole of the foot part to support the ankle joint from the outside direction and the inside direction A belt-shaped first support band formed of a sexual material, and provided at one end of the first support band, detachably bonds the inner position of the crus part of the crus fixing band and the first support band A first ankle joint supporting portion having a first bonding means, and from the inside of the crus through the sole of the foot to the outer position of the crus of the crus fixing band , Extending in contact with the side surface of the ankle joint and the sole of the foot, and supporting the ankle joint from the outside direction and the inside direction. A belt-like second support band formed of a sexual material and provided at one end of the second support band, the outer position of the crus part of the crus fixing band and the second support band are detachably bonded A second ankle joint support portion having a second bonding means for performing an outer direction of the ankle joint by the first support band and the second support band which are in contact with and supported by the ankle joint side surface of the ankle joint. And restricting the rocking in the inner direction ”.

  Here, the crus fixing band is formed so as to be fixed by being wound around the crus between the ankle and the knee, and examples thereof include those formed by cloth members. Further, the crus fixing band is formed longer than the circumferential direction of the crus so as to be wound around the crus, and a conventionally known fixing such as a hook-and-loop fastener or a hook for fixing at one end thereof. Adhesive means are provided. In addition, the said crus part fixed band is a location used as the foundation for attaching and supporting the 1st support band and the 2nd support band which are mentioned later to an ankle joint. In addition, excessively extending the first support band and the second support band of the first ankle joint support part and the second ankle joint support part may affect the stability during wearing or may be the first support band during use. Since there is a high possibility that a problem such as slippage from the sole of the foot will occur, for example, it is assumed that the crus fixing band is wound around a position just above the ankle (or heel).

  On the other hand, the first support band and the second support band of the first ankle joint support part and the second ankle joint support part can be similarly formed by a cloth member, but the cloth member can be stretched by a tensile stress. Elastic materials are used.

  Therefore, according to the ankle joint reinforcement training tool of the present invention, the ankle joint side surfaces in the outer direction and the inner direction of the ankle joint are supported by the stretchable first support band and the second support band, respectively. At this time, the first support band and the second support band are supported so as to be passed from the side surfaces of the ankle joints through the soles. Therefore, although the movement of the ankle joint in the lateral direction is restricted, the movement of the ankle joint in the dorsiflexion and plantar flexion directions is not restricted. Therefore, as in the prior art, the ankle joint can be supported without completely fixing the movement of the ankle joint. In particular, since it is supported by a pair of the first support band and the second support band from the outside to the inside and from the inside to the outside, stable support can be performed without biasing the center of gravity. For this reason, there is no restriction in the dorsiflexion direction and the bottom flexion direction in which the ankle joint mainly moves during normal walking motion, and motion blur in the lateral direction is reduced. As a result, the walking motion is stable, and it is also suitable for the treatment and prevention of sprains. Here, the movement of the ankle joint in the plantar flexion direction is routinely performed by the action of “kicking” the foot during walking. Therefore, the force toward the bottom flexion direction is often well trained. However, there has never been any instrument or device for training the movement of the ankle joint in the dorsiflexion direction in daily life. Therefore, by strengthening the force in the dorsiflexion direction of the ankle joint found by the applicant of the present application, a training instrument such as an ankle joint based on a theory capable of suppressing the occurrence of foot failure such as sprains, The function that can be used to train the dorsiflexion force is unique to the ankle joint strengthening training tool of the present invention.

  Therefore, according to the ankle joint reinforcement training tool of the present invention, a hook-and-loop fastener is used as the first means for adhering to the crus fixing band. Thereby, the attachment and detachment to the crus fixed band of the 1st ankle joint support part and the 2nd ankle joint support part becomes easy. Further, even when the size of the foot of the user who uses the ankle joint reinforcement training device of the present invention is different, the adjustment can be achieved by the hook-and-loop fastener and the stretchable first and second support bands. The present invention can be applied to a wide range of subjects such as large adults or elderly people with small foot sizes.

  Further, the ankle joint strengthening training tool of the present invention may include, in addition to the above configuration, “at least one of the first support band of the first ankle joint support part and the second support band of the second ankle joint support part. One of them is further provided with a lower leg attaching portion for wrapping and fixing the lower leg on the other end opposite to the one end provided with the first adhesive means or the second adhesive means. It may be “characteristic”.

  Therefore, according to the ankle joint reinforcement training tool of the present invention, the first support band and the second support band are wound around the lower leg (including the ankle joint) separately from the lower leg fixing band (separately). It further has a crus attachment part for fixing. Therefore, the starting point of the first support band can be determined without being limited to the crus fixing band. As a result, even if the size of the user's lower leg and ankle joint is large, the first ankle joint and the second ankle joint formed independently of the lower leg fixation band are matched to the size. The position can be changed as appropriate. Therefore, even if it is an ankle joint reinforcement training tool of one size, it becomes possible to respond to users with a wide range of foot sizes.

  Further, the ankle joint strengthening training tool of the present invention may include, in addition to the above configuration, “at least one of the first support band of the first ankle joint support part and the second support band of the second ankle joint support part. One of them may be connected to the crus fixing band along a direction substantially orthogonal to the winding direction of the crus fixing band.

  Therefore, according to the ankle joint reinforcement training tool of the present invention, the first support band and the second support band are directly connected to the crus fixing band, respectively. Here, after the first support band and the second support band are connected to the crus fixing band, after the crus fixing band is wound around the crus and fixed, Positioning when supporting the ankle joint side surface of the ankle joint is easy. As a result, the wearing of the ankle joint strengthening training tool of the present invention is simplified. The first support band, etc. attached to a predetermined position of the crus fixing band is a place corresponding to the outer position and inner position of the ankle joint when the crus fixing band is wrapped around and fixed to the crus. It is installed with setting. Therefore, when the ankle and crus sizes are used for a standard user, it is preferable to have a configuration in which the crus fixing band and the first support band are connected in advance as described above. It is.

  As an effect of the present invention, only the lateral movement of the ankle joint is restricted, and the movement in the dorsiflexion direction and the bottom flexion direction is made free, so that there is no lateral deflection and the dorsiflexion force and the bottom flexion force. Can be stabilized. As a result, the force in the dorsiflexion direction (dorsiflexion force) can be trained. By strengthening the dorsiflexion force found by the applicant of the present application, a failure such as a sprain on the ankle joint is prevented, and a treatment for the failure is also provided. Can be performed. Furthermore, even an elderly person who is difficult to walk can improve the walking motion by stabilizing such dorsiflexion force. In addition, as described above, when the ankle joint strengthening training device of the present invention is used, the movement of the ankle joint in the dorsiflexion direction and the bottom flexion direction is not regulated, so that even if it is worn, it can be seated straight. it can. Therefore, even elderly people do not hesitate to use it.

  In other words, unlike conventional treatment for sprains, it does not completely regulate the movement of the ankle, but only regulates movement in the direction in which pain is likely to occur (side of the ankle joint) and is mainly used for walking movements. The movement in the dorsiflexion and bottom flexion directions is not restricted. As a result, the walking motion can be advanced without feeling uncomfortable as before spraining. Furthermore, the recovery from sprains can be made favorable.

  Hereinafter, an ankle joint strengthening training tool 1 (hereinafter simply referred to as “training tool 1”) according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. Here, FIG. 1 is an explanatory view showing a schematic configuration of the training tool 1 of the present embodiment, FIG. 2 is an explanatory view showing an example of wearing the training tool 1 on the right foot RF, and FIG.

FIG. 6 is an explanatory diagram showing an example of wearing the training tool 1 on the left foot LF. In addition, the training tool 1 of this embodiment shall be attached to both the left and right legs RF and LF, respectively, and an example will be described which is used mainly for the purpose of stabilizing the walking motion of an elderly person (user).

  As shown in FIGS. 1 to 6, the training tool 1 of the present embodiment includes a belt-like crus fixing band 2 that is wound around and fixed to the crus 5 of the right foot RF of a user (not shown), A first support band 10 is attached to the ankle joint 7 of the user's foot 6 and is in contact with the ankle side surfaces 8a and 8b and the sole 9 to support the ankle side surfaces 8a and 8b. The first ankle joint support portion 3 and the second ankle joint support portion 4 having the second support band 11 are mainly provided.

  More specifically, the crus fixing band 2 is formed of a cloth member, has a band length longer than the outer circumference of the crus part 5 and is formed of a wide band-shaped member. Therefore, by winding the crus fixing band 2 around the crus 5, it is possible to wind at least one round. Further, a fixing surface fastener 12 is attached to one end of the crus fixing band 2 so that the state where the crus fixing band 2 is wound around the crus 5 and fixed can be maintained.

  On the other hand, the first ankle joint support unit 3 includes a first support band 10 configured to include elastic rubber-like fibers, a first surface fastener 13 provided at one end of the first support band 10, A string-like shape that extends from the vicinity of the other end facing the one end 10a of the first support band 10 provided with the one-surface fastener 13 and is wound around the lower leg 5 for fixing the first ankle joint support 3 The first lower leg attaching part 14 is provided. Here, the 1st surface fastener 13 is equivalent to the 1st adhesion | attachment means in this invention, and the 1st leg part attaching part 14 is equivalent to the leg part attaching part in this invention. The first surface fastener 13 is detachably bonded to a part of the surface of the above-described crus fixing band 2.

  Similarly, the second ankle joint support portion 4 includes a second support band 11 configured to include elastic rubber fibers, a second surface fastener 15 provided at one end of the second support band 11, A string that extends from the vicinity of the other end of the second support band 11 provided with the second surface fastener 15 and faces the other end 11a and is wound around and fixed to the lower leg 5 And a second lower leg attachment portion 16. Here, the 2nd surface fastener 15 is equivalent to the 2nd adhesion | attachment means in this invention, and the 2nd leg part attaching part 16 is equivalent to the leg part attaching part in this invention. The second surface fastener 15 is detachably bonded to a part of the surface of the crus fixing band 2 described above.

  Further, the first ankle joint support part 3 and the second ankle joint support part 4 will be described in detail. The string-like first crus attachment part 14 of the first ankle joint support part 3 is wound around the crus part 5 in advance. It is attached so as to cover the surface of the lower belt of the attached crus fixing band 2. Here, a female hook-and-loop fastener 17 is provided on the surface of the extended portion of the first crus attaching part 14 extending from the first support band 10, while the string-like first crus attaching part 14 is provided. A male surface fastener 18 is provided at one end. Therefore, by winding the first crus attachment part 14 around the crus part 5 and overlapping the male surface fastener 18 on the female surface fastener 17, the surface fasteners 17 and 18 are bonded to each other. The first ankle joint support 3 is attached to the thigh 5. Similarly, the second ankle joint support portion 4 is provided with a female surface fastener 17 and a male surface fastener 18 on the second crus attachment portion 16 (details are omitted). Of course, the male / female relationships of the hook-and-loop fasteners 17 and 18 may be interchanged.

  Next, the mounting method of the training tool 1 of the present embodiment and the strengthening and training of the dorsiflexion force and the like using this will be described. First, the crus fixing band 2 is wound around and fixed to the crus 5 of the foot to be worn (here, the right foot RF). As described above, since the fixing surface fastener 12 is attached to one end of the crus fixing band 2, a part of the surface of the crus fixing band 2 of the fixing surface fastener 12 is brought into close contact. Can be glued. The fixing surface fastener 12 is a well-known fixing and bonding means, and details thereof are omitted. As a result, a state in which the crus fixing band 2 is wound around the approximate center of the crus 5 is created (see FIG. 3). The crus fixing band 2 may be attached to the crus 5 as long as it is attached, but as shown in FIG. 2 and the like, the crus fixing band 2 should be wound just above the ankle joint, that is, immediately above the heel. What is to be done is suitable.

  Thereafter, the first crus attaching part 14 of the first ankle joint supporting part 3 is wound around the belt surface near the lower part of the crus fixing band 2. At this time, the first support band 10 is adjusted so as to be positioned on the ankle joint side surface 8a outside the foot portion 6, and is fixed so as to be held at the position by the female surface fastener 17 and the male surface fastener 18 described above. (See FIG. 4). Thereby, the 1st support belt 10 will be in the state where it hung down from the outside of an ankle joint. Then, one end 10a of the first support band 10 is bent (arrow A in FIG. 4: folded back from the front side of the paper toward the depth direction), and passes through the sole 9 to the opposite ankle joint side surface 8b (FIG. 6). (See reference). Then, the 1st surface fastener 13 provided in the one end 10a of the 1st support belt | band | zone 10 is adhere | attached with a part of belt surface of the crus part fixed band 2 wound around the crus part 5 (refer FIG. 6). At this time, since the first support band 10 is made of a stretchable material, the first support band 10 is slightly extended and supported by the above operation. Thereby, the ankle joint side surfaces 8a and 8b and the sole 9 are covered with the first support band 10. As a result, the lateral movement of the ankle joint 7 is restricted, and the movement in the dorsiflexion direction and the bottom flexion direction (see arrows B and C in FIG. 2) is not restricted.

  Further, similarly, the second ankle joint support portion 4 is attached so as to overlap the first ankle joint support portion 3. Here, since the attachment method has changed the 1st ankle joint support part 3 and the outer side and the inner side, detailed description is abbreviate | omitted. That is, the second crus attaching part 16 is wound so as to cover the crus fixing band 2 and the first crus attaching part 14 and is positioned on the inner ankle joint side face 8b (see FIG. 6). Thus, the second support band 11 is supported by the surface fasteners 17 and 18 so as to hang down from the position (see FIG. 5). Then, one end 11a of the first support short 11 is bent (arrow D in FIG. 4: folded back from the depth direction of the paper surface toward the front side of the paper surface), and is passed along the ankle joint side surface 8a via the sole 9. . Then, the second surface fastener 15 is bonded to a part of the belt surface of the crus fixing band 2 wound around the crus 5 (see FIG. 2). As a result, the ankle joint side surfaces 8 a and 8 b and the sole 9 are covered with the second support band 11. Thereby, the ankle joint can be supported by the support bands 10 and 11 from both sides by the second ankle joint support portion 4 together with the first ankle joint support portion 3, and the movement in the direction can be restricted. Thereby, the movement to a dorsiflexion direction and a bottom flexion direction is not controlled. Here, in FIGS. 2 and 5, etc., the positions where the first support band 10 and the second support band 11 are in contact with the soles 9 are set near the front of the heel, but the present invention is limited to this. It is not a thing. For example, the contact position may be set near the arch of the sole 9. Here, since the vicinity of the arch has a shape that is recessed from the heel and the toe, it is expected that the support is more stable when the first support belt 10 and the second support belt 11 are supported across the arch. .

  And mounting | wearing of the training tool 1 of this embodiment with respect to the right leg RF mentioned above is similarly implemented also with respect to the left leg LF (refer FIG. 6). Thereby, the training tool 1 is mounted on both feet. At this time, as described above, the lateral movement of each foot 6 (or ankle joint) is restricted. As a result, even in elderly people who have difficulty in walking due to such lateral movement, that is, shaking, the back of the ankle joint 7 is suppressed by suppressing the shaking from both sides by the first support band and the second support band. The movement in the bending direction and the bottom bending direction can be stabilized. Therefore, compared with before mounting | wearing the training tool 1 of this embodiment, walking motion can be stabilized. Then, by continuing the walking motion while wearing the training tool 1 of the present embodiment, the correct way of moving the foot 6 can be learned, and even when the training tool 1 is removed, the original stable walking can be performed. It becomes possible.

  Furthermore, the training tool 1 of the present embodiment has a function of regulating the movement of the ankle joint described above, strengthening the dorsiflexion force and stabilizing the walking motion, and is also used for prevention and treatment of normal sprains and the like. It is possible.

  That is, since the movement of the ankle joint in the lateral direction can be restricted, it is possible to prevent an excessive force in the direction when the sprain is applied to the ankle joint. Furthermore, even when an excessive force is applied to the ankle joint, the ankle joint is protected by the training tool 1, so that the possibility of spraining can be reduced.

  Moreover, the training tool 1 of this embodiment is formed so that the belt-like crus fixing band 2, the first ankle joint support part 3, and the second ankle joint support part 4 can be independently separated from each other. Therefore, even for a user whose size of the lower leg 5 or the foot 6 or the ankle joint is extremely large, or conversely extremely small, by appropriately changing the position fixed by the hook-and-loop fastener or the like, Even the training tool 1 of one size can be used for a wide range of subjects.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  That is, in the training tool 1 of the present embodiment, the crus fixing band 2 and the first ankle joint support 3 are formed independently, but the first ankle joint is not limited to this. The first support band 10 of the support part 3 and the second support band 11 of the second ankle joint support part 4 may be configured to be directly connected to the crus fixing band 2, respectively. In this case, the configuration of the first crus attaching part 14 and the second crus attaching part 16 described above can be omitted, and further, the labor for positioning the first support band 10 and the like can be omitted. Can do.

  Furthermore, in the training tool 1 of the present embodiment, the one using the surface fastener 13 or the like, which is a conventionally known fixing and bonding means, is used for the adhesion between the crus fixing band 2 and the first support band 10 or the like. The fixing and bonding means is not limited to the hook-and-loop fastener 13 or the like.
