Definitions
- the present invention relates to a body shape correction apparatus. More particularly, the present invention relates to a body-shape correction apparatus able to correct one's body shape by strengthening external rotation muscles of the hip joints and/or the shoulder joints by applying resistance against the external rotation of feet and/or hands.
- the hip joint refers to a joint positioned inside a protruding bone on the side of the hip to connect the pelvis and the femur.
- the internal rotation deformity of hip joints causes the genu varum in which legs are bent in a O-shape. In the related art, this has been corrected by surgery. However, surgery has a high cost in terms of money and time, as well as being a complicated procedure with risks involved, which is problematic.
- the applicant proposed an apparatus that corrects the legs by strengthening the external rotation muscles of the hip joint through external rotation of the feet.
- This correction apparatus can realize three levels of exercise intensity using three springs selected according to the individual levels.
- the three levels of exercise intensity can be realized by selecting the weakest spring for the exercise intensity of the first level and the strongest spring for the exercise intensity of the third level.
- the correction apparatus of the related art has not been able to realize a variety of exercise levels.
- a corresponding number of springs has been required, leading to an increase in the price of the correction apparatus.
- This also increases the size and weight of the correction apparatus, which are problematic.
- it is more difficult to obtain suitable springs able to realize such various exercise levels. For example, one hundred springs are required when fabricating a correction apparatus able to realize 100 exercise levels, and these springs must have different spring constants that are required for the springs. It is not only difficult to fabricate or purchase such precision springs, but also costs required for fabricating or purchasing the precision springs significantly increase the price of the correction apparatus even if precision springs can be fabricated or purchased.
- an object of the invention is to provide a body shape correction apparatus able to simultaneously correct the shape of the upper half of the body and the shape of the lower half of the body by combining a structure strengthening the external rotation muscles of the hip joints required for correction of the legs in the lower half of the body and a structure strengthening the shoulder muscles required for correction of the upper half of the body.
- the body shape correction apparatus can realize various exercise levels by simplifying the structure without an increase in manufacturing costs, size, or weight.
- an object of the invention is to provide a body shape correction apparatus that seniors, having problems in the elbow joints or shoulder joints can easily use, since a user can exercise with almost no movement in the elbows or shoulder joints.
- the present invention provides a body shape correction apparatus including: a left foot-accompanying rotator, on which the left foot of a user is seated and supported, rotating forward in a counterclockwise direction, and returns in clockwise direction; a right foot-accompanying rotator, on which the right foot is seated and supported, rotating forward in clockwise direction, and returns in counterclockwise direction; and a pair of spring parts and a pair of deformation distributing unit corresponding to the pair of foot-accompanying rotators.
- Each of the pair of spring parts may include first to nth springs, where n ⁇ 2.
- Each of the first to the nth springs is deformed following forward rotation of the pair of foot-accompanying rotators, where n is a natural number equal to or greater than 2. Restoring force due to the net-deformation applies resistance against the forward rotation of the foot-accompanying rotators.
- the pair of deformation distributing units distribute the net-deformations required for applying a required amount of the restoring force against forward rotation of the pair of foot-accompanying rotators to the first to nth springs.
- the spring constant of jth springs may be greater than the spring constant of (j-1)th springs, where j ranges from 2 to n.
- the body shape correction apparatus may have first to mth exercise levels at which different amounts of restoring force are applied to the pair of foot-accompanying rotators, where m is a natural number equal to or greater than 2, wherein a greater restoring force is applied to the pair of foot-accompanying rotators at a kth exercise level than at a (k-1)th exercise level.
- the spring constant of jth springs may be greater than a spring constant of (j-1)th springs, where j ranges from 2 to n.
- the pair of deformation distributing unit distributes the amount of the net-deformation such that the net-deformation of the first springs is smaller at the kth exercise level than at the (k-1)th exercise level and the net-deformation of the nth springs is greater at the kth exercise level than at the (k-1)th exercise level.
- At least one pair of the first to nth springs may have an initial deformation at the kth exercise level, wherein the initial deformation is greater at a k′th exercise level than at a (k′-1)th exercise level, where k′ is k satisfying the relationship: k ⁇ 3.
- Each of the pair of deformation distributing units may include a lever arm.
- the lever arm may rotate about a first point, and have a pulley on a second point.
- each of the second springs may form a fixed end regardless of forward rotation of the pair of foot-accompanying rotators.
- the other ends of the second springs are connected to the foot-accompanying rotators to form movable ends which move following forward rotation of the foot-accompanying rotators.
- the intermediate part between the one end and the other end is looped over the pulley such that each second spring rotates the lever arm in a first direction following the forward rotation of each foot-accompanying rotator.
- the first spring is connected to the lever arm at a third point between the first and second points, and can resist the rotation of the lever arm in the first direction.
- the angle of rotation of the lever arms rotating following forward rotation of the pair of foot-accompanying rotators may be smaller at the kth exercise level than at the (k-1)th exercise level.
- the second springs have an initial deformation at the k exercise level.
- An initial position of the one end of the second spring is set such that the initial deformation is greater at the k′th exercise level than at the (k′-1)th exercise level, where k′ is k satisfying the relationship: k ⁇ 3.
- a body shape correction apparatus including: a left hand-accompanying rotator rotating together with a left hand of a user who has let a left arm freely hung from a left shoulder joint and has stretched a left elbow joint, wherein the left hand-accompanying rotator rotates forward in counterclockwise direction following external rotation of the left hand, and returns in clockwise direction; a right hand-accompanying rotator rotating together with a right hand of the user who has let a right arm freely hung from a right shoulder joint and has stretched a right elbow joint, wherein the right hand-accompanying rotator rotates forward in clockwise direction following external rotation of the right hand, and returns in counterclockwise direction; a left elastic unit applying clockwise restoring force against counterclockwise rotation of the left hand-accompanying rotator; and a right elastic unit applying counterclockwise restoring force against clockwise rotation of the right hand-accompanying rotator.
- Each of the left and right elastic units may be one of a spiral spring, a torsion coil spring, and a torsion bar.
- the body shape correction apparatus can realize various exercise levels using a simple structure without an increase in manufacturing costs, size, or weight.
- FIG. 1 and FIG. 2 are schematic views illustrating the concept of the invention
- FIG. 3 is an exterior view illustrating a body shape correction apparatus according to a first embodiment of the present invention
- FIG. 4 and FIG. 5 are inner configuration views illustrating exercise level a in the body shape correction apparatus shown in FIG. 3 ;
- FIG. 6 and FIG. 7 are inner configuration views illustrating exercise level b in the body shape correction apparatus shown in FIG. 3 (a ⁇ b);
- FIG. 8 and FIG. 9 are inner configuration views illustrating exercise level c in the body shape correction apparatus shown in FIG. 3 (a ⁇ b ⁇ c);
- FIG. 10 is an exterior view illustrating a body shape correction apparatus according to a second embodiment of the invention.
- FIG. 11 illustrates the initial state of a hand-accompanying rotator of the body shape correction apparatus shown in FIG. 10 ;
- FIG. 12 is illustrates the hand-accompanying rotator of the body shape correction apparatus shown in FIG. 10 that has rotated forward.
- the maximum intensity of movement is determined according to the body conditions of the users. For example, seniors must have a relatively weak maximum intensity of exercise, whereas young men can have a relatively strong maximum intensity of exercise. In this manner, users can obtain maximum correction effects without stress on the bodies.
- the same user preferably starts with warming up at an initial stage, gradually increasing the intensity of exercise.
- the intensity of exercise is set to vary among exercise level 6 and exercise level 7, such that a user may not feel boring when exercising
- the exercise intensity can be adjusted.
- FIG. 1 and FIG. 2 are schematic views illustrating the concept of the invention.
- the present invention basically uses a plurality of springs, and distributes a suitable degree of deformation to each of the springs, thereby producing various amounts of resistance using the combination of restoring forces of the springs. This concept will be described below with reference to FIG. 1 and FIG. 2 .
- FIG. 1 and FIG. 2 use two springs including a first spring 210 and a second spring 220 .
- the spring constant of the second spring 220 is greater than the spring constant of the first spring 210 . It is appreciated that, when the same degree of deformation is applied, a greater amount of restoring force is generated by the second spring 220 than by the first spring 210 .
- the shape correction apparatus of the invention includes a deformation distributing unit in order to distribute suitable degrees of deformation to the plurality of springs.
- the deformation distributing unit includes a lever arm 310 .
- the lever arm 310 rotates about a first point 310 a.
- the first spring 210 is connected to the lever arm 310 adjacent to a second point 310 b
- the second spring 220 is connected to the lever arm 310 adjacent to the first point 310 a.
- the first spring 210 is connected to the lever arm 310 adjacent to the first point 310 a
- the second spring 220 is connected to the lever arm 310 adjacent to the second point 310 b.
- FIG. 2 has a greater amount of force A required to pull the second point 310 b of the lever arm 310 by the same rotational displacement than FIG. 1 . This indicates that FIG. 2 has a greater amount of resistance against a foot-accompanying rotator 101 than FIG. 1 , as will be described later.

Description
- The present invention relates to a body shape correction apparatus. More particularly, the present invention relates to a body-shape correction apparatus able to correct one's body shape by strengthening external rotation muscles of the hip joints and/or the shoulder joints by applying resistance against the external rotation of feet and/or hands.
- The hip joint refers to a joint positioned inside a protruding bone on the side of the hip to connect the pelvis and the femur. The internal rotation deformity of hip joints causes the genu varum in which legs are bent in a O-shape. In the related art, this has been corrected by surgery. However, surgery has a high cost in terms of money and time, as well as being a complicated procedure with risks involved, which is problematic.
- Therefore, the applicant proposed an apparatus that corrects the legs by strengthening the external rotation muscles of the hip joint through external rotation of the feet. This correction apparatus can realize three levels of exercise intensity using three springs selected according to the individual levels. For example, the three levels of exercise intensity can be realized by selecting the weakest spring for the exercise intensity of the first level and the strongest spring for the exercise intensity of the third level.
- Therefore, the correction apparatus of the related art has not been able to realize a variety of exercise levels. In order to realize a variety of exercise levels, a corresponding number of springs has been required, leading to an increase in the price of the correction apparatus. This also increases the size and weight of the correction apparatus, which are problematic. In addition, as the number of the exercise levels required increases, it is more difficult to obtain suitable springs able to realize such various exercise levels. For example, one hundred springs are required when fabricating a correction apparatus able to realize 100 exercise levels, and these springs must have different spring constants that are required for the springs. It is not only difficult to fabricate or purchase such precision springs, but also costs required for fabricating or purchasing the precision springs significantly increase the price of the correction apparatus even if precision springs can be fabricated or purchased.
- In addition, when the muscles behind the shoulders required for external rotation of the shoulder joints are weakened, the shoulders are rolled forward, and the problems involving the shape of the upper half body and the spinal health are caused. This is frequently observed among seniors and teenagers having bad posture.
- Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the invention is to provide a body shape correction apparatus able to simultaneously correct the shape of the upper half of the body and the shape of the lower half of the body by combining a structure strengthening the external rotation muscles of the hip joints required for correction of the legs in the lower half of the body and a structure strengthening the shoulder muscles required for correction of the upper half of the body. In addition, the body shape correction apparatus can realize various exercise levels by simplifying the structure without an increase in manufacturing costs, size, or weight.
- Furthermore, an object of the invention is to provide a body shape correction apparatus that seniors, having problems in the elbow joints or shoulder joints can easily use, since a user can exercise with almost no movement in the elbows or shoulder joints.
- In order to accomplish the above object, the present invention provides a body shape correction apparatus including: a left foot-accompanying rotator, on which the left foot of a user is seated and supported, rotating forward in a counterclockwise direction, and returns in clockwise direction; a right foot-accompanying rotator, on which the right foot is seated and supported, rotating forward in clockwise direction, and returns in counterclockwise direction; and a pair of spring parts and a pair of deformation distributing unit corresponding to the pair of foot-accompanying rotators.
- Each of the pair of spring parts may include first to nth springs, where n≧2. Each of the first to the nth springs is deformed following forward rotation of the pair of foot-accompanying rotators, where n is a natural number equal to or greater than 2. Restoring force due to the net-deformation applies resistance against the forward rotation of the foot-accompanying rotators.
- The pair of deformation distributing units distribute the net-deformations required for applying a required amount of the restoring force against forward rotation of the pair of foot-accompanying rotators to the first to nth springs.
- The spring constant of jth springs may be greater than the spring constant of (j-1)th springs, where j ranges from 2 to n.
- The body shape correction apparatus may have first to mth exercise levels at which different amounts of restoring force are applied to the pair of foot-accompanying rotators, where m is a natural number equal to or greater than 2, wherein a greater restoring force is applied to the pair of foot-accompanying rotators at a kth exercise level than at a (k-1)th exercise level.
- The spring constant of jth springs may be greater than a spring constant of (j-1)th springs, where j ranges from 2 to n. The pair of deformation distributing unit distributes the amount of the net-deformation such that the net-deformation of the first springs is smaller at the kth exercise level than at the (k-1)th exercise level and the net-deformation of the nth springs is greater at the kth exercise level than at the (k-1)th exercise level.
- At least one pair of the first to nth springs may have an initial deformation at the kth exercise level, wherein the initial deformation is greater at a k′th exercise level than at a (k′-1)th exercise level, where k′ is k satisfying the relationship: k≧3.
- Each of the pair of deformation distributing units may include a lever arm.
- The lever arm may rotate about a first point, and have a pulley on a second point.
- The n may be 2. One end of each of the second springs may form a fixed end regardless of forward rotation of the pair of foot-accompanying rotators. The other ends of the second springs are connected to the foot-accompanying rotators to form movable ends which move following forward rotation of the foot-accompanying rotators. The intermediate part between the one end and the other end is looped over the pulley such that each second spring rotates the lever arm in a first direction following the forward rotation of each foot-accompanying rotator. The first spring is connected to the lever arm at a third point between the first and second points, and can resist the rotation of the lever arm in the first direction.
- The angle of rotation of the lever arms rotating following forward rotation of the pair of foot-accompanying rotators may be smaller at the kth exercise level than at the (k-1)th exercise level.
- The second springs have an initial deformation at the k exercise level. An initial position of the one end of the second spring is set such that the initial deformation is greater at the k′th exercise level than at the (k′-1)th exercise level, where k′ is k satisfying the relationship: k≧3.
- In an aspect of the present invention, provided is a body shape correction apparatus including: a left hand-accompanying rotator rotating together with a left hand of a user who has let a left arm freely hung from a left shoulder joint and has stretched a left elbow joint, wherein the left hand-accompanying rotator rotates forward in counterclockwise direction following external rotation of the left hand, and returns in clockwise direction; a right hand-accompanying rotator rotating together with a right hand of the user who has let a right arm freely hung from a right shoulder joint and has stretched a right elbow joint, wherein the right hand-accompanying rotator rotates forward in clockwise direction following external rotation of the right hand, and returns in counterclockwise direction; a left elastic unit applying clockwise restoring force against counterclockwise rotation of the left hand-accompanying rotator; and a right elastic unit applying counterclockwise restoring force against clockwise rotation of the right hand-accompanying rotator.
- Each of the left and right elastic units may be one of a spiral spring, a torsion coil spring, and a torsion bar.
- According to the present invention as set forth above, it is possible to simultaneously correct the upper half and the lower half of the body instead of performing a body shape correction exercise for only either the lower half or the upper half at one time. In addition, the body shape correction apparatus can realize various exercise levels using a simple structure without an increase in manufacturing costs, size, or weight.
- In addition, it is possible to conveniently and easily strengthen the external rotation muscles of the shoulder joints with an easy action without moving the shoulder joint or the elbow joint. In particular, since exercise is performed at the neutral position of the shoulder joint and the elbow joint, a person having an ache in the shoulder joint or the elbow joint or weak muscular strength in the shoulder joint or the elbow joint can use the correction apparatus with no difficulties. Furthermore, due to the simple structure, manufacturing costs can be advantageously reduced.

FIG. 12 is illustrates the hand-accompanying rotator of the body shape correction apparatus shown inFIG. 10 that has rotated forward. - Reference will now be made in detail to exemplary embodiments of the invention in conjunction with the accompanying drawings.
- In a body shape correction apparatus according to an exemplary embodiment of the invention, the following environments of use were considered.
- The maximum intensity of movement is determined according to the body conditions of the users. For example, seniors must have a relatively weak maximum intensity of exercise, whereas young men can have a relatively strong maximum intensity of exercise. In this manner, users can obtain maximum correction effects without stress on the bodies.
- In addition, even the same user preferably starts with warming up at an initial stage, gradually increasing the intensity of exercise. At the middle stage, it is preferable to maintain a strong intensity of exercise as the main exercise mode. At the final stage, it is preferable to gradually decrease the intensity of exercise as a finishing mode.
- In addition, even at the initial stage in which the intensity of exercise is increased macroscopically, the middle stage in which the intensity of exercise is maintained macroscopically, or the final stage in which the intensity of exercise is reduced macroscopically, it is preferable to increase, maintain, or reduce the intensity of exercise macroscopically while repeating an increase and decrease in the intensity of exercise in a microscopic fashion such that exercises are not boring. For example, it is more preferable to macroscopically increase the intensity of exercise at the initial stage while continuously varying the intensity of exercise in a microscopic fashion as in first exercise level→second exercise level→third exercise level→second exercise level→third exercise level→fourth exercise level→third exercise level, instead of linearly increasing the intensity of exercise, as in first exercise level→second exercise level→third exercise level, or gradually increasing the intensity of exercise, as in first exercise level→first exercise level→second exercise level→second exercise level→third exercise level. For example, assuming that a user has to repeat the forward rotation/
return 50 times in a single set of exercise and the maximum exercise level is exercise level 7, it is not preferable that the exercise level 7 is maintained at the middle stage of exercise without a change in intensity. it is preferable that the intensity of exercise is set to vary among exercise level 6 and exercise level 7, such that a user may not feel boring when exercising - In order to obtain various effects of exercise, the exercise intensity can be adjusted.
-
FIG. 1 andFIG. 2 are schematic views illustrating the concept of the invention. - The present invention basically uses a plurality of springs, and distributes a suitable degree of deformation to each of the springs, thereby producing various amounts of resistance using the combination of restoring forces of the springs. This concept will be described below with reference to
FIG. 1 andFIG. 2 . -
FIG. 1 andFIG. 2 use two springs including afirst spring 210 and asecond spring 220. The spring constant of thesecond spring 220 is greater than the spring constant of thefirst spring 210. It is appreciated that, when the same degree of deformation is applied, a greater amount of restoring force is generated by thesecond spring 220 than by thefirst spring 210. - The shape correction apparatus of the invention includes a deformation distributing unit in order to distribute suitable degrees of deformation to the plurality of springs. Referring to
FIG. 1 andFIG. 2 , the deformation distributing unit includes alever arm 310. - The
lever arm 310 rotates about afirst point 310 a. InFIG. 1 , thefirst spring 210 is connected to thelever arm 310 adjacent to asecond point 310 b, and thesecond spring 220 is connected to thelever arm 310 adjacent to thefirst point 310 a. InFIG. 2 , thefirst spring 210 is connected to thelever arm 310 adjacent to thefirst point 310 a, and thesecond spring 220 is connected to thelever arm 310 adjacent to thesecond point 310 b. - Consequently, when pulling the
second point 310 b of thelever arm 310 by the same rotational displacement, a greater amount of deformation is applied to the first spring than the second spring inFIG. 1 , and a greater amount of deformation is applied to the second spring than the first spring inFIG. 2 . - Therefore,
FIG. 2 has a greater amount of force A required to pull thesecond point 310 b of thelever arm 310 by the same rotational displacement thanFIG. 1 . This indicates thatFIG. 2 has a greater amount of resistance against a foot-accompanyingrotator 101 thanFIG. 1 , as will be described later. - From the point of view of the deformation distributing unit, a greater exercise level of displacement is distributed to the
first spring 210 having a smaller spring constant in order to produce a smaller amount of resistance as inFIG. 1 , but a greater exercise level of displacement is distributed to thesecond spring 220 having a greater spring constant in order to produce a greater amount of resistance as inFIG. 2 . - Correction apparatuses illustrated in
FIG. 3 toFIG. 9 are more practical examples of the correction apparatus illustrated inFIG. 1 andFIG. 2 . -

FIG. 3 , the body shape correction apparatus according to the foot-accompanyingrotators 101 includes, as external components, handles 10, abackrest 20, ahousing 30, and foot-accompanyingrotators 101. - The
handles 10 help a user use the correction apparatus, while standing and mounting on the foot-accompanyingrotators 101. Thebackrest 20 supports the back of the user to improve the convenience of the user. Thehousing 30 protects inner components illustrated inFIG. 4 toFIG. 9 . - A pair of the foot-accompanying
rotators 101 includes a right foot-accompanying rotator and a left foot-accompanying rotator. The foot-accompanyingrotator 101 depicted on the left ofFIG. 3 is a right foot-accompanying rotator on which the right foot of the user is supported, and the foot-accompanyingrotator 101 depicted on the right ofFIG. 3 is a left foot-accompanying rotator on which the left foot of the user is supported. The user steps on the foot-accompanyingrotators 101, stretches the knee at the neutral position of the hip joints, and rotates feet forward together with the foot-accompanying rotators. -

The correction apparatus includes a left deformation distributing unit corresponding to the left foot-accompanying rotator and a right deformation distributing unit corresponding to the right foot-accompanying rotator. - The spring part includes the
first spring 210 and thesecond spring 220. The spring constant of thesecond spring 220 is greater than the spring constant of thefirst spring 210. When the springs are deformed by the same displacement, the restoring force of thesecond spring 220 is greater than that of thefirst spring 210. Although the springs are illustrated as being coil springs inFIG. 4 toFIG. 9 , this is illustrative only, and the present invention is not limited thereto. - The deformation distributing unit includes the
lever arm 310. Thelever arm 310 turns about a stationaryfirst point 310 a, and has a pulley at asecond point 310 b. - One end of the
second spring 220 forms a fixed end that is not influenced by the forward rotation of the foot-accompanyingrotators 101, and the other end of thesecond spring 220 is connected to the foot-accompanyingrotators 101, forming a movable end that moves following the forward rotation of the foot-accompanyingrotators 101. The intermediate part between the one end and the other end of thesecond spring 220 are looped over thepulley 320, and rotate thelever arm 310 in the first direction in cooperation with the forward rotation of the foot-accompanyingrotators 101. Thesecond spring 220 has aspring body 221 and aconnector 223, in which theconnector 223 is preferably wound on thepulley 320. For example, when the coil spring is used as a spring body, the coil spring may be caught by the pulley, preventing smooth operation. However, the spring body may be positioned at any portion except for the portion of the spring wound on the pulley. AlthoughFIG. 4 toFIG. 9 illustrate that the spring body is positioned at the portion close to one end of the second spring, the spring body may be positioned at the portion close to the other end, or the spring body may be positioned close to both one and the other ends. - One end of the
first spring 210 is fixed to onestationary point 210 a, and the other end of thefirst spring 210 is fixed to thethird point 310 c between thefirst point 310 a and thesecond point 310 b of thelever arm 310, resisting the rotation of thelever arm 310 in the first direction. - When the foot-accompanying rotator rotates forward about a
point 105, the second spring is deformed. When the second spring pulls thesecond point 310 b of the lever arm while being deformed, the lever arm rotates in the first direction about thefirst point 310 a. Consequently, the first spring is also deformed. When the foot-accompanying rotator rotates forward, the first spring is deformed following the forward rotation of the foot-accompanying rotator. A net-deformation indicates the amount of deformation produced by deducting an initial deformation from a total deformation. Thefirst spring 210 has a restoring force due to the net-deformation of thefirst spring 210, and thesecond spring 220 has a restoring force due to the net-deformation of thesecond spring 220. Due to the restoring force of thefirst spring 210 and the restoring force of thesecond spring 220, resistance is applied to the forward rotation of the foot-accompanyingrotators 101. - The body shape correction apparatus has first to mth exercise levels (m is a natural number equal to or greater than 2) in which different amounts of resistance are applied to the forward rotation of the foot-accompanying
rotators 101. At the kth exercise level (k ranges from 2 to m), a greater amount of resistance than at the (k-1)th exercise level is applied to the forward rotation of the foot-accompanyingrotators 101.FIG. 6 andFIG. 7 show a higher exercise level thanFIG. 4 andFIG. 5 , andFIG. 8 andFIG. 9 show a higher exercise level thanFIG. 6 andFIG. 7 . - The deformation distributing unit distributes the amount of net-deformation required for applying required resistance to the forward rotation of the foot-accompanying
rotators 101 to thefirst spring 210 and thesecond spring 220. The deformation distributing unit distributes the amount of net-deformation such that the net-deformation of thefirst spring 210 in the kth exercise level is smaller than that in the (k-1)th exercise level and the net-deformation of thesecond spring 220 in the k exercise level is greater than that in the (k-1) exercise level. That is, the amount of net-deformation of thefirst spring 210 is greatest inFIG. 4 andFIG. 5 (smallest resistance is applied to the forward rotation of the foot-accompanying rotator) and is smallest inFIG. 8 andFIG. 9 (greatest resistance is applied to the forward rotation of the foot-accompanying rotator). In contrast, the amount of net-deformation of thesecond spring 220 is smallest inFIG. 4 andFIG. 5 and is greatest inFIG. 8 andFIG. 9 . - At a lower exercise level, the
lever arm 310 is rotated about thefirst point 310 a by a large rotation angle to distribute a greater amount of net-deformation to thefirst spring 210 and a smaller amount of net-deformation to thesecond spring 220. However, at a higher exercise level, thelever arm 310 is rotated about thefirst point 310 a by a small rotation angle to distribute a smaller amount of net-deformation to thefirst spring 210 and a greater amount of net-deformation to thesecond spring 220. Consequently, at an exercise level in which a large amount of net-deformation is distributed to the second spring having a large spring constant, a significant amount of resistance can be applied against the forward rotation of the foot-accompanying rotator. - The
first spring 210 and thesecond spring 220 may have an initial deformation at the kth exercise level. It is preferable that the initial deformation at the k′th exercise level is greater than that at the (k′-1)th exercise level (where k′ is k satisfying the relationship: k≧3). For this, the higher the exercise level is, the more the initial position of the one end of thesecond spring 220 is moved, such that that thesecond spring 220 has a greater amount of initial deformation. When thesecond spring 220 has a greater amount of initial deformation and pulls thesecond position 310 b of thelever arm 310 with a greater amount of force, thelever arm 310 is further rotated in the first direction, and thefirst spring 210 also has a greater amount of initial deformation. When thefirst spring 210 and thesecond spring 220 have initial deformations, the initial restoring force due to the initial deformations requires greater amounts of force to rotate the foot-accompanyingrotators 101 forward. - A
motor 410, ascrew shaft 420, and amovable block 430 may be provided in order to impart the initial deformation to the second spring by moving the one end of the second spring. The motor rotates the screw shaft that has threads on the outer circumference thereof. When the screw shaft rotates, the movable block having a screw-hole into which the screw shaft is screwed moves along the screw shaft. The one end of the second spring is fixed to the movable block. -
FIG. 10 is an exterior view illustrating a body shape correction apparatus according to a second embodiment of the invention. - Referring to
FIG. 10 , the body shape correction apparatus shown inFIG. 10 differs from the body shape correction apparatus shown inFIG. 3 in that thehandles 10 are substituted by hand-accompanyingrotators 50. The left hand-accompanying rotator rotates together with the left hand of a user who has let the left arm hung from the left shoulder joint and has stretched the left elbow joint. The left hand-accompanying rotator rotates forward in the counterclockwise direction following external rotation of the left hand, and returns in the clockwise direction. The right hand-accompanying rotator rotates along with the right hand of a user who has let the right arm hung from the right shoulder joint and has stretched the right elbow joint. The right hand-accompanying rotator rotates forward in the clockwise direction following external rotation of the right hand, and returns in the counterclockwise direction. - Although
FIG. 10 illustrates the structure in which the user grasps and rotates the hand-accompanyingrotators 50, the present invention is not limited thereto. Rather, a variety of other embodiments are possible. For example, the user can fixedly insert hands into the hand-accompanying rotators while opening the hands, and rotates the hand-accompanying rotators together with the hands. -
FIG. 11 illustrates the initial state of a hand-accompanying rotator of the body shape correction apparatus shown inFIG. 10 , andFIG. 12 is illustrates the hand-accompanying rotator of the body shape correction apparatus shown inFIG. 10 that has rotated forward. - Each of the hand-accompanying
rotators 50 is hinged to astationary bar 60. For this, thestationary bar 60 has astationary ring 61 on one end thereof. In addition, the hand-accompanyingrotator 50 has arotary shaft 51 on one end thereof. Therotary shaft 51 of the hand-accompanyingrotator 50 rotates in the state in which it is fitted into thestationary ring 61 of thestationary bar 60. - The correction apparatus illustrated in
FIG. 10 includes a left elastic unit and a right elastic unit in order to apply restoring force to the pair of hand-accompanyingrotators 50. The left elastic unit applies clockwise restoring force against the counterclockwise rotation of the left hand-accompanying rotator, whereas the right elastic unit applies counterclockwise restoring force against the clockwise rotation of the right hand-accompanying rotator. - The
elastic unit 70 is typically implemented as a spring.FIG. 10 toFIG. 12 illustrate the embodiment in which a spiral sprig is used as theelastic unit 70. Alternatively, a torsion coil spring, a torsion bar, or the like can be used. The inner end of the spiral spring is fixed to the fixingring 61, whereas the outer end of the spiral spring is fixed to the hand-accompanyingrotator 50 at a position spaced apart from therotary shaft 51. - The body shape correction apparatus illustrated in
FIG. 10 toFIG. 12 may have first to mth exercise levels (m is a natural number equal to or greater than 2) in which different amounts of restoring force are applied to the pair of hand-accompanyingrotators 50. It is possible to apply a greater amount of restoring force to the pair of hand-accompanyingrotators 50 at the kth exercise level (k ranges from 2 to m) than at the (k-1) exercise level. - For example, the pair of
elastic units 70 has an initial deformation at the kth exercise level, and the initial deformation may be greater at the k′th exercise level than at the (k′-1)th exercise level (k′ is k satisfying the relationship k≧3). For this, for example, at the second exercise level, the spiral spring is given the initial deformation by rotating thestationary ring 61 counterclockwise by 10°. At the third exercise level in which a greater amount of restoring force is required, the spiral spring is given a greater amount of initial deformation by further rotating thestationary ring 61 counterclockwise by 10°. (In this structure, thestationary ring 61 must have a structure rotatable with respect to the remaining portion of the fixing bar 60 (the remaining portion except for the fixing ring 61).) - The hand-accompanying rotators illustrated in
FIG. 10 toFIG. 12 can correct the upper body shape of a user by strengthening muscles for external rotation of the shoulder joints. - Although
FIG. 10 illustrates an embodiment in which the hand-accompanying rotators and the foot-accompanying rotators are provided in a single apparatus, this is not intended to be limiting. For example, a dedicated correction apparatus including only the hand-accompanying rotators without the foot-accompanying rotators may also be embodied.
