Description

{BODY-SHAPE CORRECTION APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body orthodontic appliance, and more particularly, to a body orthodontic appliance which corrects the external rotation muscles of the hip and / or shoulder joint by reinforcing the external rotation of the foot and / or hand.

The hip is a joint that connects the pelvis to the femur by being located inside the bone that protrudes out of the buttocks. When the hip is internally deformed, the leg is bent into an O shape, which was conventionally corrected through surgery. However, such a surgical procedure is costly, time consuming, troublesome, and risky.

Thus, the present applicant has proposed a device for calibrating the legs of the lower body by strengthening the external rotation muscles of the hip through external rotation of the feet. In the above-described orthodontic appliance, three springs were employed, and each spring was selected in accordance with each step, thereby realizing three levels of exercise intensity. For example, in order to select the exercise intensity of the first stage, the weakest spring may be selected, and in order to select the exercise intensity of the third stage, the strongest spring may be selected.

Therefore, it is not possible to realize various exercise strengths in the orthodontic appliance. In order to realize various exercise strengths, the number of springs is required to increase the unit price of the principal apparatus, . Also, as the number of steps required increases, it is not easy to obtain a spring capable of implementing such a fine exercise intensity. For example, when manufacturing a calibration device that implements 100 steps of exercise intensity, not only 100 springs are required but each of the 100 springs must have a different spring constant that is required, It is not easy to purchase, and even if it can be manufactured or obtained, the manufacturing or purchasing cost results in a sharp increase in the unit price of the calibrating device.

On the other hand, when the muscles required for shoulder joint external rotation at the back of the shoulder are weakened, the shoulders are curled forward and may cause upper body shape and spine health problems. This is often observed in older adults and younger postures.

SUMMARY OF THE INVENTION The present invention has been conceived in order to solve the above-mentioned problems, and it is an object of the present invention to provide a body orthodontic appliance which simultaneously combines the structure for strengthening the hip joint external muscle necessary for the correction of the lower limbs and the structure for strengthening the shoulder muscle necessary for correcting the upper body, It is an object of the present invention to provide a device capable of correcting a body shape of an entire body of an upper body and a lower body. Another object of the present invention is to provide a calibration device capable of realizing various exercise strengths through a simple structure without increasing the manufacturing cost and increasing the size and weight.

The object of the present invention is to provide a body correcting apparatus which can easily exercise even elderly people having problems in the elbow joint and shoulder joint because the exercises can be performed with little movement of the elbow and shoulder joints.

In order to achieve the above-mentioned object, the present invention provides a portable terminal comprising: a left foot-mounted rotation unit in which a left foot of a user is seated and supported, but is clockwise and counterclockwise rotated; And a pair of spring portions and a pair of deformation amount distributing portions corresponding to the pair of foot rotating portions.

Each of the spring portions has a first spring to an nth spring (n > = 2), and each of the first spring to the n < th > Resistance force is applied before the turning of the foot-turning unit by the restoring forces due to deformations.

The deformation amount distributing unit distributes the net deformation amounts necessary for applying the resistance force to the first spring to the nth spring before the turning of the foot rotating unit.

The j-th spring (j = 2 to n) may have a spring constant larger than that of the j-th spring.

Wherein the deformation amount distributing unit distributes the deformation amount of the first spring so that the net deformation amount of the first spring is smaller in the k-th stage than in the (k-1) th stage and the net deformation amount of the n-th spring is larger in the k- The net strain quantities can be distributed.

Wherein at least one of the first spring to the n-th spring has an initial deformation amount in a k-th stage, and the initial deformation amount thereof is smaller than the first deformation amount in the k'th step (k ' It can be big.

The deformation amount distributing unit may include a lever arm.

The lever arm may rotate about the first point as a rotation axis and have a pulley at a second point.

Wherein n is 2 and the second spring has a fixed end which is one end unaffected by the turning of the foot pedal rotational part and the other end is connected to the foot pedal rotating part, And the first spring rotates the lever arm in the first direction, and the first spring rotates in the first direction and the second spring rotates in the second direction, And is connected to a third point between the two points so as to resist rotation of the lever arm in the first direction.

The rotation angle of the lever arm that is rotated in association with the forefoot rotating part may be smaller in step k than in the (k-1) th step.

The two springs have an initial deformation amount in the k-th stage, and are set such that they have a larger initial deformation amount in the k < th > stage than in the k'-1 stage (k & Can be set.

Further, according to the present invention, the left shoulder joint is easily slackened in the normal posture, the left elbow joint is rotated in conjunction with the left hand of the user, the forward rotation is counterclockwise in accordance with the external rotation of the left hand, The right hand joint is rotated together with the right hand joint and the right elbow joint is rotated together with the right hand of the user and the right hand is rotated counterclockwise in accordance with the external rotation of the right hand, A left elastic part for applying a clockwise restoring force to resist counterclockwise displacement of the left handed hand rotating part and a right elastic part for applying a counterclockwise restoring force to resist clockwise displacement of the right handed hand rotating part And a body correcting device for correcting the body position.

According to the above-described configuration, the present invention can perform not only the body-type correcting exercise of the lower half body at one time, but the upper body half correcting exercise, but also the correcting exercise of the upper body and lower body simultaneously. It is also possible to provide a body correcting device capable of realizing various exercise strengths through a simple structure without increasing the manufacturing cost and increasing the size and weight.

In addition, the external rotation of the shoulder joint muscles can be easily and easily strengthened by the uncomfortable movements of the shoulder and elbow joints, so that the upper body can be corrected. In particular, exercise in the neutral state of the shoulder joint and elbow joint, so that people with pain in the shoulder joints or elbow joints or weak muscles in the shoulder joints or elbow joints can be used without difficulty. In addition, there is an advantage that the manufacturing cost can be lowered because of the simple structure.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The body correcting apparatus according to the preferred embodiment of the present invention considers the following use environment.

It is preferable that the maximum exercise intensity should be relatively small for the elderly person and the maximum exercise intensity is relatively large for the young man according to the physical condition of the user because the maximum correction effect can be obtained without imposing a load on the body.

In addition, even in the same user, it is preferable to increase the initial exercise intensity from the weak exercise intensity to the gradually increased exercise intensity in the initial exercise mode. In the middle period, it is preferable that the strong exercise intensity is maintained as the main mode. It is preferable to gradually decrease from a strength to a weak exercise intensity.

In addition, even if the initial intensity at which the intensity of exercise increases macroscopically, the medium level at which the intensity of exercise is maintained at a macroscopic level, and the intensity at which the intensity of exercise decreases macroscopically, microscopically, the intensity increases, It is desirable to exercise without getting bored. For example, it is necessary to increase the exercise intensity linearly from the first stage to the second stage to the third stage or to increase the exercise intensity step by step like Step 1 -> Step 1 -> Step 2 -> Step 2 -> Step 3 It is necessary to increase the exercise intensity macroscopically by continuously changing the exercise intensity microscopically as in Step 1 -> Step 2 -> Step 3 -> Step 2 -> Step 3 -> Step 4 -> Step 3 May be desirable. Further, for example, in the case of performing one set of 50 exercises (the forward rotation and the return of the foot-turning unit are performed once), when the maximum exercise intensity is 7 stages, 7 stages are continuously maintained in the middle stage without changing the exercise intensity For example, it may be desirable to set the interval between steps 6 and 7 to be continuous so that the user does not feel bored when exercising at the same intensity when exercising.

In order to achieve the various exercise goals, it is desirable that the exercise intensity can be controlled in various ways.

1 and 2 are conceptual diagrams for explaining the concept of the present invention.

The present invention basically uses a plurality of springs and distributes an appropriate amount of deformation to each of the plurality of springs, and obtains various necessary resistance by combining the restoring forces obtained from these springs. This concept will be described with reference to FIGS. 1 and 2. FIG.

FIGS. 1 and 2 use two springs, a first spring 210 and a second spring 220. The spring constant of the second spring 220 is larger than the spring constant of the first spring 210. Therefore, when the same amount of deformation is made to the spring, it means that a larger restoring force is generated in the second spring 220 as compared with the first spring 210.

The calibration apparatus of the present invention includes a deformation amount distributing section for distributing an appropriate deformation quantity to a plurality of springs. 1 and 2, the deformation distribution portion includes a lever arm 310.

The lever arm 310 is rotated about the first point 310a as a rotation axis. The first spring 210 is connected to the second point 310b of the lever arm 310 and the second spring 220 is connected to the first point 310a of the lever arm 310. [ 2, the first spring 210 is connected to the first point 310a of the lever arm 310 and the second spring 220 is connected to the second point 310b of the lever arm 310 have.

Accordingly, the amount of deformation of the spring, which is involved in pulling the second point 310b of the lever arm 310 by the same rotational displacement, is larger in the first view than in the second spring, Is larger than the first spring.

Thus, the force A required to pull the second point 310b of the lever arm 310 by the same rotational displacement is greater in Fig. 2 than in Fig. This means that the resistance force applied to the foot-turning rotator 101 described later is greater in Fig. 2 than in Fig.

From the perspective of the deformation distributor, in order to obtain a relatively smaller resistance force as in FIG. 1, a larger amount of deformation is distributed to the first spring 210 having a smaller spring constant, In order to obtain a large resistance force, it is necessary to distribute a larger amount of deformation to the second spring having a larger spring constant.

It is a more practical implementation of the calibration apparatus of FIGS. 1 and 2 in the calibration apparatus of FIGS.

3 is an external view of a body correcting apparatus according to the first embodiment of the present invention.

As shown in the drawings, the body correcting apparatus according to the first embodiment of the present invention may include a handle 10, a backrest 20, a housing 30, and a foot-turning unit 101 as an external structure.

The knob 10 helps the user to climb the foot-turning portion 101 in a standing position and use the correcting device. The backrest 20 supports the back of the user to improve user convenience. The housing 30 protects the internal components shown in Figures 4-9.

The foot-driven rotation part (101) has a pair of left-footed rotation part and right-footed rotation part. In FIG. 3, the foot-turning unit 101 shown on the left side is a right-footed rotation unit in which a user's right foot is seated and supported, and a foot-related rotation unit 101 shown on the right is a left- . The user climbs to the pivotal rotation part, stretches the knee joint in the neutral state of the hip joint, and rotates the foot together with the pivotal rotation part.

On the outer periphery of the foot-driven rotation unit 101, the jaws 103 and 104 are provided on the left and right sides, respectively, so as not to release the feet.

Fig. 4 and Fig. 5 are internal diagrams showing the step a in the calibration apparatus of Fig. 3, showing front and rear of the forward rotation of the foot rotating unit, respectively. Fig. 6 and Fig. 7 are internal diagrams showing the step b (a < b) in the calibration apparatus of Fig. 3, respectively showing the front and rear of the forward rotation of the foot rotating unit. Fig. 8 and Fig. 9 are internal diagrams showing the step (c < b < c) in the calibration apparatus of Fig. 3, respectively showing the front and rear of the forward rotation of the foot rotating unit.

4 to 9) is forwardly rotated in the counterclockwise direction and returned in the clockwise direction. The right-handed swinging portion (the pedal swinging portion shown on the right in Figs. 4 to 9) is rotated clockwise and counterclockwise. The orthodontic appliance has a left spring portion corresponding to the left foot synchronous rotation portion and an right spring portion corresponding to the right foot synchronous rotation portion. The orthodontic appliance has a left deformation amount distributing part corresponding to the left foot synchronous rotating part and a right deformation amount distributing part corresponding to the right toe rotating part.

The spring portion has a first spring (210) and a second spring (220). The second spring 220 has a greater spring constant than the first spring 210. Thus, when deformed by the same amount, the second spring 220 has a greater restoring force than the first spring 210. [ 4 to 9 show a coil spring as a spring, but this is merely an example, and the present invention is not limited thereto.

The deformation amount distribution portion includes a lever arm 310. The lever arm 310 rotates about the first point as the rotation axis and has the pulley 320 at the second point 310b.

The other end of the second spring 220 is connected to the foot rotating portion 101 and is moved by the forward rotation of the foot rotating portion 101, As shown in Fig. The one end of the second spring 220 is wrapped around the pulley 320 and interlocked with the pedal rotation portion 101 to rotate the lever arm 310 in the first direction. The second spring 220 preferably has a spring body 221 and a connecting body 223, and a portion of the second spring 220 that is wound around the pulley 320 is a connecting body. For example, when the coil spring is used as the spring main body, the coil spring is caught by the pulley, which may hinder smooth operation. However, any part other than the part to be rolled up on the pulley may come in the spring main body. 4 to 9 illustrate that the spring main body comes near the one end of the second spring, but the spring main body may come close to the other end, or the spring main body may come to the one end and the vicinity of the other end .

One end of the first spring 210 is fixed to one point 210a and the other end is connected to a third point 310b between the first point 310a of the lever arm 310 and the second point 310b 310c to resist rotation of the lever arm 310 in the first direction.

The second spring is net-deformed when the foot-driven rotation unit is rotated clockwise about the one point (105). When the second spring 310 of the lever arm is pivoted to the second position 310b while the second spring is being deformed, the lever arm rotates the first point 310a in the first direction with the rotation axis. Thus, the first spring is net-deformed. That is, when the foot rotating unit is rotated forward, the first spring is also net-deformed in association with the rotation. Here, the net strain means a strain obtained by subtracting the initial strain described later from the total strain. The first spring 210 has a restoring force due to its net deformation. The second spring 220 also has a restoring force due to its net deformation. The restoring force of the first spring 210 and the restoring force of the second spring 220 apply the resistance force before the turning of the foot rotating portion 101. [

The body correcting apparatus has first to m-th steps (m &gt; = 2) for applying different resistive forces to the foot-turning unit 101 before the foot is rotated. In the k-th step (k = 2 to m), a larger resistance force is applied before the forward rotation of the foot rotation unit 101 than in the (k-1) th step. Figures 6 and 7 show steps higher than Figures 4 and 5, and Figures 8 and 9 show steps higher than Figures 6 and 7.

The deformation amount distributing unit distributes the net deformation amounts necessary for imparting the resistance force to the first spring 210 and the second spring 220 before the forward rotation of the foot turning unit 101. The deformation amount distribution unit may be configured such that the net deformation amount of the first spring 210 is smaller in the k-th stage than in the (k-1) th stage and the net deformation amount of the second spring 220 is smaller than that in the The net deformation quantities are distributed to be larger. That is, the net deformation amount of the first spring 210 is the largest in Figs. 4 and 5 (the resistance force applied before the forward rotation of the foot-rotating unit is the smallest), and Figs. 8 and 9 Is the largest). On the other hand, the net strain amount of the second spring 220 is the smallest in Figs. 4 and 5, and is the largest in Figs. 8 and 9.

The lever arm 310 is rotated at a large number of rotation angles about the first point 310a in the low stage to distribute a large amount of net deformation to the first spring 210 and a small net deformation amount to the second spring 220 Distribution. However, in the high stage, the first point 310a is rotated by a small angle of rotation about the first point 310a to distribute a small net strain amount to the first spring 210 and to distribute a large amount of net strain to the second spring 220. [ As a result, at a high stage in which a large amount of net deformation is distributed to the second spring having a large spring constant, a large resistance force can be applied before the turning of the foot rotating portion.

Meanwhile, the first spring 210 and the second spring 220 may have an initial deformation amount in the k-th stage. It is preferable that the initial deformation amount is larger in the k &lt; th &gt; step than in the k &apos; -th step (k &apos; To this end, as the step increases, the initial position of one end of the second spring 220 is moved so that the second spring 220 has a larger initial deformation amount. When the second spring 220 has a larger initial deformation and pulls the second point 310b of the lever arm 310 with greater force, the lever arm 310 is further rotated in the first direction and the first spring 210) also have a larger amount of deformation. When the first spring 210 and the second spring 220 have an initial amount of deformation, a greater force is required to rotate the foot-turning unit 101 forward due to the initial restoring forces due to these initial deformation amounts.

A screw shaft 420 and a moving block 430 to move the one end of the second spring to give an initial amount of deformation to the second spring. The motor rotates the screw shaft. The screw shaft is formed with a thread on its outer periphery. When the screw shaft is rotated, the moving block having the screw hole screwed with the screw shaft is moved along the screw shaft. One end of the second spring is fixed to the moving block.

10 is a schematic view of a body correcting apparatus according to a second embodiment of the present invention.

As shown in FIG. 10, the body-type orthodontic appliance of FIG. 10 has a structure in which the handhold 10 is replaced by a hand-held rotational portion 50 as compared with the body type orthodontic appliance of FIG. The left handed swivel part is rotated along with the left hand of the user who squeezes the left shoulder joint and the left elbow joint. The left hand concurrent rotary part is rotated in the counterclockwise direction in accordance with the external rotation of the left hand and is returned in the clockwise direction. The right-handed swivel part is rotated along with the right hand of the user, with the right shoulder joint stretched and the right elbow joint. The right-handed rotation section is rotated in the clockwise direction in accordance with the external rotation of the right hand, and is returned in the counterclockwise direction.

10 shows a structure in which the user grasps and rotates the hand-held rotating portion 50, but the present invention is not limited thereto. For example, various modifications are possible, for example, a structure in which a user inserts and fixes a hand in a hand-operated rotation portion in a unilateral state, and a hand and a hand-rotation portion rotate together.

FIG. 11 is a view showing an initial state of a right-handed rotational portion of the body-type orthodontic appliance of FIG. 10, and FIG. 12 is a view showing a forward rotational state of a right-handed rotational portion of the body-

The hand-held swinging unit 50 is hinged to the fixed bar 60. [ For this purpose, a fixing ring 61 is formed at an end of the fixing bar 60. A rotating shaft 51 is formed at an end of the hand-held rotating portion 50. The rotary shaft 51 of the hand-held rotary unit 50 is rotated while being inserted into the stationary ring 61 of the stationary bar 60.

10 has a left elastic portion and a right elastic portion in order to apply a restoring force to the pair of hand-held rotary portions 50. As shown in Fig. The left elastic part applies a clockwise restoring force against the counterclockwise displacement of the left hand rotating part. The right resilient portion imparts a counterclockwise restoring force against the clockwise displacement of the right hand rotating portion.

As the elastic portion 70, a spring is typically used. Figs. 10 to 12 show an embodiment in which a spiral spring is used as the elastic portion 70. Fig. In addition, a torsion coil spring, a torsion bar, or the like may be used. The inner end of the spiral spring is fixed to the fixed ring 61 and the outer end of the spiral spring is fixed to the hand-held rotating portion 50 at a position spaced from the rotating shaft 51 by a predetermined distance.

10 to 12 may have first to m-th steps (m ≥ 2) of applying restoring forces of different sizes to the pair of hand-held rotary parts 50. In this case, In the k-th stage (k = 2 to m), the restoring forces larger than in the (k-1) th stage can be applied to the pair of hand-held rotation units 50.

For example, the pair of elastic portions 70 have an initial deformation amount in the k-th stage, and the initial deformation amount thereof is smaller in the k'th stage than in the k''-1 stage (k 'satisfies k? 3) Can be greatly increased. For this purpose, for example, in the second step, the fixing ring 61 is rotated counterclockwise by 10 degrees to give an initial amount of deformation to the spiral spring, and in the third step requiring a larger restoring force, To give a larger initial strain to the spiral spring. (In this structure, the fixing ring 61 should have a structure capable of rotating with respect to the remaining portion of the fixing bar 60 (the remaining portion except for the fixing ring 61)

The hand coordinated rotation unit 50 shown in Figs. 10 to 12 can strengthen the muscles required for the external rotation of the shoulder joint, thereby correcting the upper half body shape of the user.

In FIG. 10, an embodiment in which the hand-driven rotation part is provided together with the foot-driven rotation part in one device, is not limited thereto. For example, it is also possible to construct a dedicated calibration device having only a hand-driven rotation part without a foot-rotating part.
