Further, as shown in FIG. 1, the training set 2 includes, in addition to the training equipment 1 described above, a plurality of types of protrusions 30A and 30B that are replaceable with the protrusion 30. Since the training equipment 1 and the training set 2 are respectively fixed to both feet of the user 50, the training equipment 1 and the training set 2 further include members having the same structure as the illustrated members.

<Plate>
The plate portion 10 is a rectangular plate body and has an upper surface 10a on which the foot 51 of the user 50 is mounted, and a lower surface 10b located on the opposite side of the upper surface 10a and facing the ground G. The protrusion 30 is fixed to the lower surface 10 b of the plate 10.

A concave portion (step portion) 12 is provided on the lower surface 10b of the plate portion 10. The recess 12 has a rectangular shape extending in the front-rear direction in a plan view. The recess 12 has a facing surface 12a extending in the front-rear direction and facing in the left-right direction.

Inside the concave portion 12 of the plate portion 10, a plurality of (five in the present embodiment) through holes 11 that penetrate vertically are provided. The plurality of through holes 11 are arranged in the front-rear direction at intervals of about 5 mm. A fixing bolt 35 (not shown) is inserted into the plate portion 10 of the through hole 11 through the plate portion 10, and the protruding portion 30 is fixed to the plate portion 10 by the fixing bolt 35. The fixing position of the protrusion 30 with respect to the plate 10 can be changed according to the physical constitution of the user 50 by selecting the through hole 11 into which the fixing bolt 35 is inserted. That is, the plurality of through holes 11 function as a front-back position adjusting unit that enables adjustment of the front-rear positional relationship between the plate portion 10 and the protrusion 30. A through hole (not shown) is provided at the opening of the through hole 11 located on the upper surface 10a side of the plate portion 10, and the head of the fixing bolt 35 is housed in the down hole.

As shown in FIG. 1, four band insertion holes 15 for inserting the fixing bands 21A and 21B of the fixing portion 20 are provided at four corners of the plate portion 10. The band insertion holes 15 are long holes that extend in the front-rear direction.

The plate portion 10 is preferably smaller than the size of the sole of the foot 51 of the user 50 supposed. As an example, when the user 50 is assumed to be male or female from elementary school students to adults, the size of the plate portion 10 in the front-rear direction is preferably 130 mm to 150 mm and the size in the left-right direction is preferably 50 mm to 70 mm. ..

<Fixed part>
As shown in FIGS. 2 to 4, the fixing portion 20 fixes the plate portion 10 to the foot 51 of the user 50. In the present embodiment, it is assumed that the shoe 55 is fixed to the foot 51 in a worn state, but when the game related to the ips is performed with bare feet, the shoes may be fixed to the bare feet.

As shown in FIG. 1, the fixing portion 20 includes a front fixing portion 20A that fixes the front portion of the plate portion 10 to the foot 51, and a rear fixing portion 20B that fixes the rear portion of the plate portion 10 to the foot 51. The front fixing portion 20A and the rear fixing portion 20B each include a first fixing band 21, a second fixing band 22, and a binding tool 24.

The first fixing band 21 and the second fixing band 22 are connected to the plate portion 10 by inserting them into the band insertion holes 15 of the plate portion 10 to loop them and then caulking the rivets 23. The binding tool 24 is fixed to the tip of the first fixing band 21. The binding tool 24 is detachably connectable to the second fixing band 22 and the connection position can be easily changed. As a result, the front fixing portion 20A and the rear fixing portion 20B can securely fix the plate portion 10 to the foot 51 by tightening the foot 51. It should be noted that the fixing portion 20 may have another configuration as long as the plate portion 10 can be fixed to the foot 51 of the user 50. For example, a side release buckle may be used as the binding tool 24 that fixes the first fixing band 21 and the second fixing band 22.

<Protrusion>
As shown in FIG. 1, the protruding portion 30 is fixed to the lower surface 10b of the plate portion 10 with a fixing bolt 35. The protrusion 30 has a hemispherical shape having a flat upper surface 32 and protrudes downward. The protrusion 30 has a vertex C as the lowermost point on the lower side. The vertex C serves as a contact point that comes into contact with the ground G when the user 50 wearing the training equipment 1 stands upright. In addition, the protrusion 30 is provided with end faces 31 that are opposite to each other in the left-right direction and that are flat and parallel to each other. The distance between the end surfaces 31 in the left-right direction is the same as or slightly smaller than the distance between the facing surfaces 12 a of the recess 12. Since the protrusion 30 is located in the recess 12, the end face 31 is fitted between the facing faces 12a. At this time, the end surface 31 and the facing surface 12a contact each other. As a result, rotation of the protrusion 30 with respect to the plate 10 is suppressed, and the fixing bolt 35 does not loosen.

<Effect>
The training brace 1 of the present embodiment is intended to improve the ips by allowing the user 50 to repeatedly perform the ips-related operation while being attached to both legs of the user 50 holding the ips. Here, the movement related to ips means a competitive movement in which the ips symptom of the user appears, and the training brace 1 exerts an effect on ipps in various sports. Examples of the movement relating to the ips include a pitching movement of baseball, a putter of golf, a serve of tennis, and the like. It has been confirmed that the training brace 1 of the present embodiment has a high effect on the ips particularly for the pitching motion of baseball.

The present inventor has obtained the following knowledge through listening and investigations on athletes holding ips and trial and error for improvement of ips. That is, the present inventor focused on the fact that the athlete holding the ips feels the loss of the body axis, and obtained the knowledge that the ips can be improved by performing the training for experiencing the body axis. .. Here, the body axis is a straight line which is imagined by the athlete as penetrating vertically through the body. The body axis is an abstract idea as an image and consciousness that is the center of the athlete's trunk. Originally, the consciousness or image of the body axis is often unconscious of the athlete. Therefore, it is considered that the body axis is not conscious of ordinary athletes.
In addition, it is considered that the athlete holding the ips has a feeling that the soles of his feet have lost the sense of the reaction force (floor reaction force) received from the ground. An ordinary athlete controls the movement of his/her weight during the competition motion by unconsciously feeling the floor reaction force received on the sole of the foot. In contrast, athletes with ips lose control of weight transfer due to the loss of the sensation of floor reaction force, and the body axis exceeds the sensation due to the inertial force associated with upper body movements. It moves, and the feeling of loss of body axis is promoted.

The training equipment 1 is in a state in which it is difficult to balance the body of the user 50 (the athlete holding the ips) who has lost the sense of the body axis. The user 50 can remember the sensation of the body axis unconsciously by repeatedly performing the movement related to the ips in a state where it is difficult to balance. That is, the user 50 can acquire the body axis again in the movement to balance, stabilize the trunk, and improve the ips.

Further, the training brace 1 of the present embodiment enhances the sensation of the body axis and the sensation of the floor reaction force, stabilizes the trunk, and reproduces repetitive motions even when used by a player who does not hold ips. The accuracy can be increased. That is, it is effective in improving performance in various sports. Further, the training brace 1 of the present embodiment is also effective for posture correction and gait control. In particular, it is effective for the rehabilitation of gait control or posture correction of an elderly person who has a hunched posture. That is, according to the training brace 1, the posture can be corrected and the walking can be smoothed.

In the training equipment 1 of the present embodiment, the respective configurations such as the height and radius of the protruding portion 30 and the positions of the plate portion 10 and the protruding portion 30 fixed by the fixing portion 20 are optimized in order to exert the ips improving effect. ing. Hereinafter, each configuration and its effect will be specifically described.

According to the fixing portion 20 of the present embodiment, as shown in FIG. 2, the front fixing portion 20A and the rear fixing portion 20B both pass above the upper 56 of the foot 51. That is, the fixing bands 21 and 22 do not pass above the Achilles tendon. Therefore, the user 50 can freely move the ankle while wearing the training brace 1. Further, in the present embodiment, the front fixing portion 20A extends from the plate portion 10 behind the front end portion 10c, so that the foot 51 is fixed behind the front end portion 10c. Further, as described above, the front end portion 10c is located rearward of the thumb ball 53 and the little finger ball 54 of the foot 51. Therefore, the fixing portion 20 fixes the foot 51 to the plate portion 10 behind the thumb ball 53 and the little finger ball 54. Therefore, the fixing portion 20 does not hinder the bending motion of the foot 51 on the toe side. With these configurations, the fixing portion 20 can cause the user 50 to reproduce the movement related to the ips without hindering the movement of the user 50.
In addition, the fixing portion 20 of the present embodiment tightens the upper 56 of the foot 51 of the user 50 with the looped fixing bands 21 and 22. By adopting such a fixing part 20, the training device 1 can be attached to the foot 51 by easily positioning the plate part 10 at a predetermined position without performing an adjustment work.

As shown in FIG. 4, the fixing portion 20 of the present embodiment has the plate portion 10 in a state where the front end portion 10c of the plate portion 10 is located behind the thumb ball 53 and the little finger ball 54 of the foot 51 in a plan view. Is fixed to the foot 51 of the user 50. More specifically, the front end portion 10c of the plate portion 10 attached to the foot 51 is located behind a virtual line 59 connecting the center of the thumb ball 53 and the center of the little finger ball 54 in plan view. Accordingly, when the back of the foot is inclined with the toe side as the lower side, both the thumb ball 53 and the little finger ball 54 of the foot 51 can push the ground G, and the user 50 can smoothly perform the operation related to the IPS. Can be done.
Here, a case where the right-handed user 50 performs a pitching motion of baseball will be described more specifically as an example. The user 50 wearing the training equipment 1 moves the trunk forward by kicking the ground G with the right foot after stepping the left foot forward when performing the pitching motion of baseball. Since the user 50 can bring both the thumb ball 53 and the little finger ball 54 into contact with the ground G while wearing the training equipment 1, such an operation of kicking out the ground G can be smoothly performed. Such an action of kicking the ground G is not limited to the throwing action of baseball, and exists in many competitions. That is, the training equipment 1 can remind the consciousness of the body axis by allowing the user 50 to perform the competition motion without hindering the motion related to the ips. Thereby, the training equipment 1 can enhance the effect of acquiring the body axis of the user 50.

In addition, the fixing portion 20 of the present embodiment uses the plate portion 10 in a state where the rear end portion 10d of the plate portion 10 is positioned rearward with respect to the lower end 52a of the calcaneus 52 of the foot 51 in a plan view. Fasten to 50 feet 51. Here, the lower end 52a of the calcaneus 52 means the tip located at the lowermost side of the calcaneus 52, and refers to the part that becomes a contact point with the ground G when the sole of the foot stands on the ground G. Since the rear end portion 10d is located posterior to the lower end 52a of the calcaneus 52, the heel of the foot 51 is surely mounted on the plate portion 10. As a result, the fixation of the plate portion 10 and the sole of the foot 51 can be stabilized, and even when the user 50 performs the operation related to the ips with the training brace 1 attached, the plate portion 10 is It is difficult for the bottom of the foot 51 to slip. If the plate portion 10 is displaced on the sole of the foot 51, the body axis to be conscious during the operation may be illusion that the body axis moves during the operation, which may hinder the acquisition of the body axis. .. According to the training equipment 1 of the present embodiment, since the rear end portion 10d is located posterior to the lower end 52a of the calcaneus 52, it is possible for the user 50 to reproduce the movement related to the IPS without feeling uncomfortable to wear. Can contribute to improvement.

The fixing portion 20 of the present embodiment positions the apex C in plan view inside the triangle T that connects the thumb ball 53, the little finger ball 54, and the calcaneus 52 of the foot 51, and the plate portion 10 is used by the user. Fasten to 50 feet 51. The user 50 supports the weight on the sole of the foot 51 by the three points of the thumb ball 53, the little finger ball 54 and the calcaneus 52. For this reason, since the vertex C is provided inside the triangle T that connects these three points, the user 50 feels his/her weight on the sole of the foot 51 and can stand independently while keeping balance. .. This makes it easier for the user 50 to be aware of his/her body axis, and the effect of improving the ips is enhanced. Moreover, it is preferable that the apex C is located on the center of gravity P of the user 50 when the user 50 is viewed from the side. Thereby, the user 50 can more clearly obtain the sensation of supporting his/her weight at the apex C of the protrusion 30 directly below the center of gravity line P by shifting the posture from the upright state to the inclined state, The acquisition of the body axis is further promoted, and the IPS of the user 50 is improved.

The height of the vertex C of the protrusion 30 is preferably 15 mm or more and 40 mm or less with respect to the lower surface 10b of the plate portion 10. By setting the height of the apex C to be 15 mm or more, the posture of the user 50 can be made sufficiently unstable, and the effect of body axis acquisition can be obtained. On the other hand, if the height of the apex C exceeds 40 mm, the posture of the user 50 may be too unstable, and the operation related to the ips may not be performed. Therefore, the height of the vertex C is preferably 40 mm or less.

The radius of the protrusion 30 is preferably 15 mm or more and 35 mm or less. When the radius of the protrusion 30 is large, the movement speed of the center of gravity line P becomes slow with respect to the posture of the user 50 (that is, the body axis) and the inclination speed of the back surface of the foot 51. On the other hand, when the radius of the protrusion 30 is small, the moving speed of the center of gravity line P with respect to the posture of the user 50 and the tilting speed of the back surface of the foot 51 becomes faster. That is, the responsiveness of instability changes according to the radius of the protrusion 30. By setting the radius of the protrusion 30 to be 15 mm or more and 35 mm or less, it is possible to realize the responsiveness of instability that is effective in improving the IPS.

In addition, in this embodiment, the protrusion 30 has a spherical shape, and has the same radius from the vertex C to the front, rear, left, and right. However, the radii of inclination from the apex C to the front, rear, left, and right may be different in the range of 15 mm or more and 35 mm or less, and the radius of curvature continuously changes during the inclination. Good. That is, the protrusion 30 may be inclined from the vertex C toward the front, the rear, the left, and the right with a continuous radius of curvature of 15 mm or more and 35 mm or less, respectively.

<Training set>
As shown in FIG. 1, the training equipment 1 constitutes a training set 2 together with a plurality of types of protrusions 30A and 30B that are replaceable with the protrusion 30. The protrusions 30A and 30B have a hemispherical shape having a flat upper surface 32 and project downward as in the case of the protrusion 30 described above. The protrusions 30A and 30B differ from the protrusion 30 in the height of the vertex C and the radius of the hemisphere. The training set 2 includes, in addition to the above-described protrusions 30, 30A, and 30B, a plurality of different ones or two or more of the height of the vertex C and the front, rear, left, and right curvature radii. It may have different types of protrusions. The user 50 selects the most suitable protrusion from among a plurality of types of protrusions 30, 30A, 30B according to his/her physique and fixes it to the plate 10. Further, the fixing of the protrusions 30, 30A, 30B to the plate portion 10 is performed by inserting the fixing bolt 35 into the through hole 11 selected from the plurality of through holes 11 according to the physique of the user 50. .. With these configurations, it is possible to provide the training equipment 1 that is effective for improving the IPS for the users 50 having a wide range of physiques.

<Modification>
Next, the protrusion 130 of Modification 1 and the protrusion 230 of Modification 2 that can be used in the above-described training equipment 1 and training set 2 will be described.
FIG. 5: is a side view of the training equipment 1A which employ|adopted the protrusion part 130 of the modified example 1, and the foot 51 of the user 50 who mounted the training equipment 1A. FIG. 6 is a side view of the training brace 1B that employs the protrusion 230 of the second modification and the foot 51 of the user 50 who wears the training brace 1.
The same components as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 5, in the protrusion 130 of the modified example 1, the radius of curvature R1 from the vertex C to the front is larger than the radius of curvature R2 from the vertex C to the rear. On the other hand, in the protrusion 230 of the modified example 2, as shown in FIG. 6, the radius of curvature R4 from the vertex C to the rear is larger than the radius of curvature R3 from the vertex C to the front. The radii of curvature R1, R2, R3, and R4 are not less than 15 mm and not more than 35 mm, and are not necessarily uniform.

Athletes who lose their senses of body axes and have ips are roughly classified into athletes who tend to have a forward leaning posture and athletes that tend to have a backward leaning posture in the movements related to ips.
It is preferable that the athlete who tends to take a backward leaning posture uses a training equipment that is configured to lose balance in the backward leaning posture. Therefore, such an athlete preferably uses the training equipment 1A including the protrusion 130 of the first modification. In the training equipment 1A, the radius of curvature R1 toward the front is larger than the radius of curvature R2 toward the rear, so that the backward movement of the center of gravity line P when the user 50 who wears the device 50 leans backward. Responsiveness becomes high as compared with the forward movement of the center of gravity line P. Therefore, the user 50 becomes difficult to maintain the balance and becomes difficult to stand when he/she tries to take a backward tilted posture. As a result, it is possible to promote the acquisition of the correct body axis by realizing that the person is in the backward leaning posture.
On the other hand, it is preferable that the athlete who tends to lean forward uses the training equipment 1B including the protrusion 230 of the second modification. By using the training brace 1B, the user 50 becomes difficult to be independent when trying to take a forward leaning posture, realizes that the user 50 is in the forward leaning posture, and promotes acquisition of a correct body axis. it can.

The protrusion 130 of the modification 1 and the protrusion 230 of the modification 2 may be a common component. That is, as the protrusion 230, the protrusion 130 may be reversed back and forth and fixed to the plate-shaped portion. As a result, the number of constituent parts of the training equipment 1B can be reduced and the cost can be reduced.

<Second Embodiment>
The training equipment 301 of 2nd Embodiment is demonstrated. The same components as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 7 is an exploded perspective view of the training equipment 301 of this embodiment. The training equipment 301 includes the plate portion 10, the fixed portion 20 (the front fixed portion 20A and the rear fixed portion 20B), and the protrusion 330 fixed to the lower surface 10b of the plate portion 10 and protruding downward. In addition, the protrusion 330 is located at the lower end, and is between the lower end member 335 and the plate portion 10, and the lower end member 335 that is inclined from the vertex C toward the front, rear, left, and right with continuous radii of curvature, respectively. A plurality of (two in the illustrated example) intervening members 336 are interposed.

A concave portion (step portion) 312 is provided on the lower surface 10b of the plate portion 10. The recess 312 has a rectangular shape extending in the front-rear direction in a plan view. The recess 312 has a facing surface 312a extending in the front-rear direction. The lower surface 10b of the plate portion 10 is provided with a plurality of through holes 11 penetrating vertically so as to cover the facing surface 312a. A fixing bolt 35 (not shown) is inserted through the plate portion 10 into the plate portion 10 in any of the plurality of through holes 11, and the fixing bolt 35 fixes the protrusion portion 330 to the plate portion 10.

The interposition member 336 has a columnar shape. The intervening member 336 is provided with a through hole 337 penetrating vertically. The fixing bolt 35 is inserted into the through hole 337. Further, a step 338 is provided on each of the upper surface 336a and the lower surface 336b of the interposition member 336. The step 338 between the upper surface 336a and the lower surface 336b overlaps each other in a plan view. Therefore, the thickness H1 (for example, 5 mm) of the interposition member 336 is constant at any position. The step 338 on the upper surface 336a has a first end surface 338a that faces the left-right direction. Similarly, the step 338 of the lower surface 336b has a second end surface 338b that faces the left-right direction. The first end surface 338a and the second end surface 338b face in opposite directions.

The first end surface 338a of the upper intervening member 336 of the two intervening members 336 faces and contacts the facing surface 312a of the plate portion 10. As a result, the upper interposition member 336 is prevented from rotating with respect to the plate portion 10.
The second end surface 338b of the upper interposition member 336 faces and contacts the first end surface 338a of the lower interposition member 336. As a result, the lower interposition member 336 is prevented from rotating with respect to the upper interposition member 336.

The lower end member 335 has a substantially hemispherical shape and projects downward by a height H2 (for example, 15 mm). The lower end member 335 has a vertex C as the lowermost point on the lower side. The lower end member 335 inclines from the apex C toward the front, the rear, the left, and the right with continuous radii of curvature, respectively. The lower end member 335 has a step 338 on the upper surface 332. The step 338 on the upper surface 332 has an end surface 331 that faces the left-right direction. The upper surface 332 is provided with a screw hole 339 extending vertically so as to overlap the end surface 331. The fixing bolt 35 inserted into the interposition member 336 is screwed into the screw hole 339. As a result, the lower end member 335 and the two intervening members 336 are fixed to the plate portion 10. The end surface 331 of the lower end member 335 faces and contacts the second end surface 338b of the lower interposition member 336. As a result, the lower end member 335 is prevented from rotating with respect to the lower intervening member 336, and the fixing bolt 35 does not loosen.

In the training equipment 301 of this embodiment, the protrusion 330 has a lower end member 335 and a plurality of interposition members 336. The interposition member 336 is sandwiched between the plate portion 10 and the lower end member 335 along the vertical direction. Therefore, the height of the apex C of the protrusion 330 with respect to the lower surface 10b of the plate portion 10 can be easily adjusted by adjusting the number of the intervening members 336 used. Also in this embodiment, the height of the apex C of the protrusion 330 is preferably 15 mm or more and 40 mm or less with respect to the lower surface 10 b of the plate 10. In this embodiment, the lower end member 335 has a height H2 of 15 mm, and the interposition member 336 has a height H1 of 5 mm. Accordingly, the protrusion 330 can have the height of the apex C of 15 mm when the interposition member 336 is not used. Further, the protrusion 330 can have the height of the apex C of 40 mm when five intervening members 336 are used. That is, the protrusion 330 can adjust the height of the apex C stepwise between 15 mm and 40 mm by adjusting the number of the intervening members 336 used between 0 and 5.

Although various embodiments of the present invention have been described above, each configuration and the combination thereof in each embodiment is an example, and addition, omission, substitution, and substitution of the configuration are within the scope not departing from the spirit of the present invention. Other changes are possible. The present invention is not limited to the embodiments.
For example, in the above-described embodiment, the fixing portion fixes the plate portion to the user's foot with the fixing band, but other configurations may be adopted as long as the same effect can be obtained.
