Description

Body shape correction device {BODY-SHAPE CORRECTION APPARATUS}

The present invention relates to a body shape correction apparatus, and to a body shape correction apparatus for correcting by strengthening the external rotation muscles of the hip and/or shoulder joint by applying resistance to external rotation of the feet and/or hands.

The hip joint refers to a joint that connects the pelvis and the femur by being located on the inside of the convexly protruding bone in the side of the hip. When the hip joint is internally rotated, the leg is bent in a five (O) shape, which has been corrected through surgery. However, such a method through surgery requires a lot of cost and time, cumbersome procedures, and risks.

Therefore, the present applicant has proposed a device for correcting the lower body leg by strengthening the hip joint external rotation muscle through external rotation of the foot. In the orthodontic device, three springs were employed, and each spring was selected according to each step, thereby implementing three levels of exercise intensity. For example, in order to select the exercise intensity of the first step, the weakest spring is selected, and to select the exercise intensity of the third step, the strongest spring can be selected, thereby implementing three levels of exercise intensity.

Therefore, the corrective device could not implement various exercise intensities, and in order to implement various exercise intensities, as many springs were required, which increased the unit cost of the principal device, and increased the size and weight of the orthodontic device. There was a problem with this. In addition, as the number of required steps increases, it is difficult to obtain a spring capable of implementing such a detailed exercise intensity. For example, when trying to manufacture a calibration device that implements 100 steps of exercise intensity, not only 100 springs are required, but the 100 springs must each have different spring constants required. Not only is it not easy to buy, and even if it can be manufactured or obtained, the manufacturing or purchase cost results in a sharp increase in the unit price of the calibration device.

On the other hand, when the muscles required for external rotation of the shoulder joint in the back of the shoulder are weakened, the shoulder is rolled forward, which can cause problems with the upper body shape and spinal health. This is often observed in older people and teenagers with poor posture.

The present invention was conceived to solve the above problems, in a body shape correction device, by combining a structure for strengthening the external rotator muscles of the hip joint required for correction of the lower body leg and a structure for strengthening the shoulder muscles required for the correction of the upper body at the same time It is an object of the present invention to provide a device capable of correcting the body shape of the upper and lower body. In addition, an object of the present invention is to provide a correction device capable of implementing a variety of exercise intensities through a simple structure without increasing manufacturing cost and increasing size and weight.

In addition, an object of the present invention is to provide a body shape correction device that can be easily used by the elderly who have problems with elbow joints or shoulder joints since they can exercise with little movement of the elbow and shoulder joints.

In order to achieve the above object, the present invention, the user's left foot is seated and supported, but rotated forward in a counterclockwise direction and returned to the clockwise rotation, and the user's right foot is seated and supported, but rotated in a clockwise direction. It includes a right foot companion rotation unit that is returned in a counterclockwise direction, and a pair of spring units and a pair of deformation amount distribution units to correspond to the pair of foot companion rotation units.

The spring part has a first spring to an nth spring (n ≥ 2), and each of the first to nth springs (a natural number of n ≥ 2) is deformed in order by interlocking with the forward rotation of the foot rotation part. A resistance force is applied to the forward rotation of the rotating part with the foot by restoring forces due to deformations.

The deformation amount distribution unit distributes the net deformation amounts necessary for applying the resistance force to the forward rotation of the foot rotation unit to the first spring to the nth spring.

The jth spring (j=2~n) may have a larger spring constant than the j-1th spring.

The body shape correction device has a first to mth step (a natural number of m ≥ 2) of applying different resistance forces to the forward rotation of the foot accompanying rotation unit, and in the kth step (k = 2 to m), the k-1 The resistance force greater than that in the step may be applied to the forward rotation of the rotating part with the foot.

The deformation amount distribution unit, so that the net deformation amount of the first spring is smaller in the kth step than in the k-1th step, and the net deformation amount of the nth spring is greater in the kth step than in the k-1th step, The net deformation amounts can be distributed.

At least one of the first spring to the nth spring has an initial deformation amount in the kth step, and the initial deformation amount is more in the k'th step than in the k'-1th step (k' is k satisfying k ≥ 3) It can be big.

The strain distribution unit may include a lever arm.

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

Wherein n is 2, the second spring forms a fixed end at one end that is not affected by the forward rotation of the foot accompanying rotation unit, and the other end is connected to the foot companion rotation unit, and is moved by the forward rotation of the foot companion rotation unit. A stage is formed, and a distance between one end and the other end is wound on the pulley and is interlocked with the forward rotation of the foot accompanying rotation unit to rotate the lever arm in a first direction, and the first spring includes the first point and the second end. It is connected to the third point between the two points, and can resist rotation of the lever arm in the first direction.

The rotation angle of the lever arm rotated in connection with the forward rotation of the foot accompanying rotation unit may be smaller in the kth step than in the k-1th step.

The second spring has an initial deformation amount in the kth step, but the initial position of the end of the end has a larger initial deformation amount in the k'th step than in the k'-1 step (k' is k satisfying k ≥ 3) Can be set.

In addition, the present invention is rotated with the left hand of the user who comfortably hangs the left shoulder joint and straightens the left elbow joint in a standing position, but is rotated counterclockwise according to the external rotation of the left hand, and is returned clockwise. , The left hand companion rotation unit, and the right shoulder joint and the right shoulder joint are stretched comfortably and the right elbow joint is rotated together with the user's right hand, but the right hand rotates clockwise according to the external rotation of the right hand, and returns to the counterclockwise direction. Comprising a rotating part with a hand, a left elastic part for applying a clockwise restoring force to resist counterclockwise displacement of the left-handed rotating part, and a right elastic part for applying a counterclockwise restoring force to resist clockwise displacement of the right-handed rotating part It provides a body shape correction device characterized in that to.

The left and right elastic parts may be springs, in particular, spiral springs, torsion coil springs, or torsion bars.

According to the above configuration, the present invention can perform the correction exercise of the upper body and the lower body at the same time, not only the body shape correction exercise of the lower body or the upper body body shape correction exercise at a time. In addition, there is an effect of providing a body shape correction device capable of implementing various exercise intensities through a simple structure without increasing manufacturing cost and increasing size and weight.

In addition, the upper body shape can be corrected by strengthening the external rotator muscles of the shoulder joint with a comfortable motion that does not move the shoulder joint and the elbow joint. In particular, since the exercise is performed in a neutral state of the shoulder joint and the elbow joint, even a person with pain in the shoulder joint or elbow joint or weak muscle strength in the shoulder joint or elbow joint can be used without difficulty. In addition, there is an advantage of lowering the manufacturing cost due to the simple structure.

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

The body shape correction apparatus according to the preferred embodiment of the present invention considers the following usage environment.

Depending on the physical condition of the user, for example, the maximum exercise intensity should be relatively small for the elderly and the maximum exercise intensity for young men is relatively large, so that the maximum corrective effect can be obtained without exerting a strain on the body.

In addition, even for the same user, it is desirable to gradually increase from weak exercise intensity to strong exercise intensity as a warm-up mode initially, and to maintain strong exercise intensity as the main mode in the middle period, and strong exercise as a finishing mode at the end. It is desirable to gradually decrease from intensity to weak exercise intensity.

In addition, even in the early stages when the exercise intensity increases macroscopically, the middle period when the exercise intensity is maintained macroscopically, and the end stage when the exercise intensity decreases macroscopically, the exercise intensity increases and decreases microscopically, increasing, maintaining, and decreasing macroscopically. It is desirable to exercise so that you do not get bored. For example, increase the intensity of exercise linearly, such as step 1 -> step 2 -> step 3, or step 1 -> step 1 -> step 2 -> step 2 -> step 3 Rather than increasing the value, increase the exercise intensity macroscopically by continuously changing the exercise intensity microscopically, such as step 1 -> step 2 -> step 3 -> step 2 -> step 3 -> step 4 -> step 3 It may be desirable to allow. In addition, for example, in the case of one set of exercise 50 times (the forward rotation and return of the rotating part with the foot is performed once), when the maximum exercise intensity is 7 steps, the 7 steps are maintained without change in the exercise intensity in the middle period. Rather, it may be desirable, for example, to keep going between steps 6 and 7 so that the user does not feel bored when exercising at the same intensity when exercising.

In order to achieve such various exercise purposes, it is preferable that the exercise intensity can be variously adjusted.

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

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

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

The straightening apparatus of the present invention includes a deformation amount distribution unit in order to distribute an appropriate amount of deformation to a plurality of springs. In FIGS. 1 and 2, the strain distribution portion includes a lever arm 310.

The lever arm 310 is rotated about the first point 310a as a rotation axis. In FIG. 1, the first spring 210 is connected close to the second point 310b of the lever arm 310 and the second spring 220 is connected close to the first point 310a of the lever arm 310. Meanwhile, in FIG. 2, the first spring 210 is connected close to the first point 310a of the lever arm 310 and the second spring 220 is connected close to the second point 310b of the lever arm 310. have.

Accordingly, when the second point 310b of the lever arm 310 is pulled by the same rotational displacement, the amount of deformation of the spring is greater than that of the second spring in FIG. 1, and the second spring in FIG. It is larger than this first spring.

Accordingly, 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. 1. This means that the resistance force applied to the foot accompanying rotation unit 101 to be described later is greater in FIG. 2 than in FIG. 1.

Viewing this from the perspective of the strain distribution unit, in order to obtain a relatively smaller resistance force as in FIG. 1, a larger amount of strain is distributed to the first spring 210 having a smaller spring constant, and relatively more as in FIG. In order to obtain a large resistance force, a larger amount of deformation is distributed to the second spring with a larger spring constant.

A more practical implementation of the calibration apparatus of FIGS. 1 and 2 is the calibration apparatus of FIGS. 3 to 9.

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

As shown, the body shape correction apparatus according to the first embodiment of the present invention may include a handle 10, a backrest part 20, a housing 30, and a foot rotation part 101 as an external configuration.

The handle 10 helps the user to use the correction device as it rises on the rotating part 101 with the foot in a standing state. The backrest part 20 improves user convenience by supporting the user's back. The housing 30 protects the internal components shown in FIGS. 4 to 9.

The foot companion rotation unit 101 includes a pair of a left foot companion rotation unit and a right foot companion rotation unit. In FIG. 3, the foot companion rotation unit 101 shown on the left is a right foot rotation unit in which the user's right foot is seated and supported, and the foot companion rotation unit 101 shown on the right is a left foot companion rotation unit in which the user’s left foot is seated and supported. . The user climbs on the foot rotation unit, stretches the knee joint in a neutral state of the hip joint, and rotates the foot together with the foot rotation unit.

The chins 103 and 104 are provided on the outer periphery of the foot accompanying rotation unit 101 so that the foot is not separated from each other.

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

The left foot companion rotation unit (the foot companion rotation unit shown on the left in FIGS. 4 to 9) rotates counterclockwise forward and returns to the clockwise direction. The right foot companion rotation unit (the foot companion rotation unit shown on the right in FIGS. 4 to 9) rotates clockwise forward and returns to the counterclockwise direction. The orthodontic device includes a left spring part corresponding to the left foot accompanying rotation part, and a right spring part corresponding to the right foot accompanying rotation part. The orthodontic device includes a left deformation amount distribution unit corresponding to the left foot accompanying rotation unit, and a right deformation amount distribution unit corresponding to the right foot accompanying rotation unit.

The spring portion has a first spring 210 and a second spring 220. The second spring 220 has a larger spring constant than the first spring 210. Therefore, when deformed by the same amount, the second spring 220 has a greater restoring force than the first spring 210. 4 to 9 illustrate a coil spring as a spring, but this is only an example, and the present invention is not limited thereto.

The strain distribution unit includes a lever arm 310. The lever arm 310 rotates with a first point as a rotation axis and has a pulley 320 at a second point 310b.

The second spring 220, one end forms a fixed end that is not affected by the forward rotation of the foot companion rotation unit 101, the other end is connected to the foot companion rotation unit 101 and moves by the forward rotation of the foot companion rotation unit 101 It forms a moving stage. The distance between one end and the other end of the second spring 220 is wound around the pulley 320 and is interlocked with the forward rotation of the foot accompanying rotation unit 101 to rotate the lever arm 310 in the first direction. The second spring 220 is provided with a spring body 221 and a connector 223, but it is preferable that the portion wound around the pulley 320 is a connector. This is because, for example, when a coil spring is used as the spring body, the coil spring may be caught in the pulley and prevent smooth operation. However, the spring body may come in any part other than the part that is wound around the pulley. 4 to 9 show that the spring body comes to a portion close to one end of the second spring, but the spring body may come at a portion close to the other end, or the spring body may come at both one end and a portion close to the other end. .

Meanwhile, the first spring 210 has one end fixed to one point 210a, and the other end a third point between the first point 310a and the second point 310b of the lever arm 310 ( 310c) and resists rotation of the lever arm 310 in the first direction.

When the foot rotation part rotates forward around a point 105, the second spring is deformed in order. When the second spring is deformed in order and pulls the second point 310b of the lever arm, the lever arm rotates about the first point 310a in the first direction with the rotation axis. Accordingly, the first spring is deformed in order. That is, when the rotating part with the foot rotates forward, the first spring is also deformed in tandem. Here, the net deformation means the total deformation minus the initial deformation described later. 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. A resistance force is applied to the forward rotation of the foot rotation unit 101 by the restoring force of the first spring 210 and the restoring force of the second spring 220.

The body shape correction apparatus has a first step to an mth step (a natural number of m ≥ 2) for applying different resistance forces to the forward rotation of the foot rotation unit 101. In the kth step (k=2~m), a greater resistance force than in the k-1th step is applied to the forward rotation of the foot accompanying rotation unit 101. 6 and 7 show higher steps than Figs. 4 and 5, and Figs. 8 and 9 show higher steps than Figs. 6 and 7.

The deformation amount distribution unit distributes the net deformation amount necessary to apply a resistance force to the forward rotation of the foot rotation unit 101 to the first spring 210 and the second spring 220. The deformation amount distribution unit is that the net deformation amount of the first spring 210 is smaller in the kth step than in the k-1th step, and the net deformation amount of the second spring 220 is smaller in the kth step than in the k-1th step. To be larger, distribute the net deformation amounts. That is, the net deformation amount of the first spring 210 is the largest in FIGS. 4 and 5 (the resistance force applied to the forward rotation of the foot accompanying rotation part is the least), and FIG. 8 and FIG. 9 (the resistance force applied to the forward rotation of the foot accompanying rotation part) Is the largest) from the smallest. On the other hand, the net deformation amount of the second spring 220 is the smallest in FIGS. 4 and 5 and the largest in FIGS. 8 and 9.

The lever arm 310 is rotated around the first point 310a by a large rotation angle at a low stage to distribute a large amount of net deformation to the first spring 210 and a small small amount of net deformation to the second spring 220. Distribute. However, in a high stage, the first point 310a is rotated around the axis by a small rotational angle, so that a small amount of net deformation is distributed to the first spring 210 and a large amount of net deformation is distributed to the second spring 220. As a result, in 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 to the forward rotation of the rotating part with the foot.

Meanwhile, the first spring 210 and the second spring 220 may have an initial deformation amount in the kth step. The initial deformation amount is preferably larger in the k'th step than in the k'-1th step (k' is k satisfying k≥3). 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 amount and pulls the second point 310b of the lever arm 310 with a greater force, the lever arm 310 is further rotated in the first direction, and the first spring ( 210) It also has a larger amount of deformation. When the first spring 210 and the second spring 220 have an initial deformation amount, a larger force is required to rotate the foot accompanying rotation unit 101 forward by initial restoring forces due to these initial deformation amounts.

In order to move one end of the second spring to give an initial amount of deformation to the second spring, a motor 410, a screw shaft 420, and a moving block 430 may be provided. The motor rotates the screw shaft. The screw shaft has a thread formed on its outer periphery. When the screw shaft is rotated, the movable block having a 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 showing a body shape correction apparatus according to a second embodiment of the present invention.

As shown, the body shape correcting device of FIG. 10 has a structure in which the handle 10 is replaced with a hand rotating part 50 compared to the body shape correcting device of FIG. 3. The left-hand companion rotation unit is rotated with the user's left hand, which droops the left shoulder joint and straightens the left elbow joint. The left-hand companion rotation unit rotates forward in the counterclockwise direction according to the external rotation of the left hand, and returns to the clockwise direction. The right hand companion rotation unit is rotated with the user's right hand, which droops the right shoulder joint and straightens the right elbow joint. The right-hand companion rotation unit rotates forward clockwise according to the external rotation of the right hand, and returns to the counterclockwise direction.

In FIG. 10, a structure in which the user grips and rotates the hand-held rotating part 50 is shown, but is not limited thereto. For example, various modifications are possible, such as a structure in which the user inserts and fixes the hand rotation unit while the hand is open, and the hand and hand rotation unit rotate together.

FIG. 11 is a view showing an initial state of the right-handed rotation unit of the body shape straightening apparatus of FIG. 10, and FIG. 12 is a view showing a forward rotational state of the right-handed rotation unit of the body shape correcting apparatus of FIG. 10.

The hand rotation unit 50 is hinged to the fixing bar 60. To this end, a fixing ring 61 is formed at the end of the fixing bar 60. In addition, a rotation shaft 51 is formed at an end of the hand rotation part 50. The rotation shaft 51 of the hand-held rotation unit 50 is rotated while being inserted into the fixing ring 61 of the fixing bar 60.

The orthodontic device of FIG. 10 has a left elastic portion and a right elastic portion in order to apply a restoring force to the pair of rotating parts 50 with hands. The left elastic portion applies a clockwise restoring force that resists counterclockwise displacement of the left-handed rotating portion. The right elastic portion exerts a counterclockwise restoring force that resists the clockwise displacement of the right-handed rotating portion.

As the elastic portion 70, a spring is typically used. 10 to 12 show an embodiment in which a spiral spring is used as the elastic part 70. In addition, torsion coil springs, torsion bars, and the like may be used. The inner end of the spiral spring is fixed to the fixing ring 61, and the outer end is fixed to the rotating part 50 with the hand at a position spaced apart from the rotation shaft 51 by a predetermined distance.

The body shape correction apparatus of FIGS. 10 to 12 may have a first step to an mth step (a natural number of m ≥ 2) of applying different sizes of restoring forces to the pair of rotating parts 50 with hands. In the k-th step (k=2 to m), the greater restoring force than in the k-1th step may be applied to the pair of rotating parts 50 with hands.

For example, the pair of elastic parts 70 has an initial deformation amount in the kth step, and the initial deformation amount is more in the k'th step than in the k'-1 step (k' is k satisfying k ≥ 3). You can make it big. To this end, for example, in the second step, the fixing ring 61 is rotated 10 degrees counterclockwise to give an initial amount of deformation to the spiral spring, and in the third step when a larger restoring force is required, the fixing ring 61 is rotated counterclockwise. This is to give the spiral spring a larger amount of initial deformation by rotating it 10 degrees further. (In this structure, the fixing ring 61 must have a structure capable of rotating with respect to the rest of the fixing bar 60 (remaining parts excluding the fixing ring 61))

The hand rotation unit 50 of FIGS. 10 to 12 can correct a user's upper body shape by strengthening muscles required for external rotation of the shoulder joint.

10 illustrates an embodiment in which the rotating part with the hand is provided with the rotating part with the foot in one device, but is not limited thereto. For example, it is possible to configure a dedicated orthodontic device having only a rotating part with a hand without a rotating part with a foot.
