Description

Stretching exercise device that pulls the whole body {STRETCHING EXERCISE DEVICE THAT CAN PULL THE WHOLE BODY}

The present invention relates to a full body stretching exercise device, which can manually or automatically adjust the intensity of spinal traction step by step, and can also adjust the height of stretching the waist region. It relates to a stretching exercise device that tractions the entire body for body alignment. .

Generally, the spine is made up of 8 neck vertebrae (cervical vertebrae), 5 back (thoracic vertebrae), the sacrum, and the tailbone (coccyx). There is an intervertebral disc between the vertebrae to support the spine.

The intervertebral disc consists of a round annulus fibrosus and a nucleus pulposus in its center, and the outside of the annulus fibrosus is covered with ligaments, which are sandwiched between the bones above and below and sealed.

According to statistics from related industries, about 80% of the Korean population suffers from back pain at least once in their lives, 7-10% of them suffer from chronic back pain, and 1% suffer from physical disabilities due to back pain. This type of back pain is most often referred to as lumbar disc herniation, commonly referred to as a disc.

The lumbar intervertebral disc herniation has become increasingly common, especially due to wrong habits in the complex lives of modern people, resulting in lower back pain.

For the treatment of the above-mentioned spinal diseases, treatments such as surgery, physiotherapy, and chemotherapy are mainly used. Among these, physiotherapy is widely used to this day because it is a simple procedure and can be expected to have a therapeutic effect without any significant side effects.

Usually, the treatment device that treats the spine consists of a mattress or bed-shaped main body that is driven by a forward-reverse motor for thermal treatment, or a moving body equipped with a roller moves in a straight line along a rail to provide fomentation and acupressure to the spine, or the main body is divided into mattresses. There was a method to correct the spine by installing a device using hydraulic pressure between the mattresses, especially by pulling the lower back.

Most of the conventional traction devices are simply traction devices that extend the spine. In particular, a structure that traction and corrects the pelvis, lumbar spine, and spine by simultaneously pulling the legs is common.

However, these devices have limited strength in traction on the spine, so there is a lack of physical response depending on the degree of spinal disease.

Moreover, there are many factors that determine the height of adolescents, including genetics, nutrition, environment, and mental factors. Among these, the most representative factors after genetic factors are acquired environmental factors. Due to these acquired environmental factors, the development of the ilium of the legs and spine is reduced, or normal growth is hindered by causing imbalance in the human body.

In addition, incorrect lifestyle habits and posture during physical development often result in an unbalanced body shape due to symptoms of scoliosis and lordosis, where the spine is curved.

To solve this problem, if you consistently do stretching exercises that straighten your body by straightening your waist for a certain amount of time every day, your body shape can be corrected by stretching the muscles and skeleton. In particular, when stretching the waist and pulling the legs of growing adolescents, it restores the growth plate and surrounding muscles from compression or pressure and relieves pressure on the growth plate, thereby promoting the secretion of growth hormones while sleeping. By doing so, it helps it grow normally or more.

In addition, the reason why growing pains occur during the growth period is because the surrounding muscles and ligaments cannot keep up with the bone growth while the bones grow rapidly, whereas the muscles grow slowly. In order to alleviate the above growing pains, the muscles and ligaments Contraction and relaxation stretching to improve flexibility are necessary.

Therefore, there is a need for the development of a full-body stretching exercise device that not only has a traction function that can be used by disc patients with back problems, but can also be effectively used by teenagers to recover the growth plate and increase the flexibility of muscles and ligaments during the growth period.

In addition, a step adjustment hole 324 is formed with a certain area to guide the movement of the guide pin 256 in the additional adjustment plate 320, and the step adjustment hole 324 adjusts the horizontal movement range of the guide pin 256 step by step. A plurality of step ledges of different heights may be formed to limit the height.

For convenience of explanation, the step ledge may be composed of a first step 325, a second step 326, and a third step 327 in order from the bottom.

Although three step jaws are shown herein, four or five step jaws may be formed and the number of step jaws is not limited.

The footrest 400 shown in FIG. 5 is installed on the extension frame 150 extending from the second frame 100 to fix the user's ankle.

In addition, the foot rest unit 400 fixes both feet of the user lying on the inclined frame unit 100 to support the spine during traction, as well as perform abdominal exercises such as sit-ups, or stretch before exercise and strengthen the body. It can play a role in preventing lower extremity venous or spinal diseases by performing traction exercises.

The footrest 400 is composed of an “L” shaped horizontal pillar 420 installed vertically in the center of the extension frame 150, and a foot support frame 440 inserted into the horizontal pillar 420. You can.

Again, the foot support frame 440 may be composed of a plurality of rotating rollers 442 and a vertical pillar 450 supporting the rotating rollers 442.

In more detail, the footrest frame 440 inserted into the horizontal pillar 420 has a plurality of fastening holes 441 formed along the longitudinal direction on the lower surface, and the horizontal pillar 420 has a bolt fastener 430. ) is installed.

The bolt fasteners 430 are selectively fastened to the plurality of fasteners 441 to determine the length of the footrest frame 440 drawn from the horizontal column 420.

That is, depending on the height of the user, the coupling position of the footrest frame 440 from the horizontal pillar 420 may be adjusted using the fastening hole 441 and the bolt fastener 430.

In addition, it is configured to include a plurality of rotating rollers 442 including a buffer pad made of a material with general elasticity to prevent feeling pressure from pressure on a specific part of the body in a right angle direction from the end side of the footrest frame 440. It can be.

That is, the rotating rollers 442 of the footrest frame 440 are arranged up and down along the vertical pillar 450, and are configured to rotate on an axis so that the user does not feel pressure from pressure on a specific part of the user, that is, both legs.

Here, a height adjustment cylinder 460 capable of adjusting the height between the rotating rollers 442 may be further installed on the vertical column 450.

As shown in FIG. 6A, a vertical pillar 450-1 with a small inner diameter is installed partially inside the hollow vertical pillar 450 to be moved up and down, and the hollow inner bottom surface of the vertical pillar 450 is used for height adjustment. A cylinder 460 is installed, and a vertical column 450-1 may be connected to the rod of the height adjustment cylinder 460.

Therefore, by operating the height adjustment cylinder 460, the vertical column 450-1 is raised and lowered inside the vertical column 450, and the height of the rotating roller 442 installed on the vertical column 450-1 can be adjusted. .

Meanwhile, in another embodiment of the present invention, in Figure 6b, a vertical pillar 450-1 with a small inner diameter is installed to be partially included inside the hollow vertical pillar 450 and moved up and down, and the vertical pillar 450 A self-contained airbag (470) is installed on the inner floor of the hollow, and the upper end of the self-contained airbag (470) can be connected to the vertical pillar (450-1).

Here, the self-contained airbag 470 can be compressed and then recharged on its own.

Furthermore, relatively elastic compression protrusions (450a) are formed protruding from both cross-sections of the lower side of the vertical pillar (450-1), and hemispherical grooves are spaced at an appropriate distance along the vertical direction on the inner surface of the vertical pillar (450). (450b) may be formed.

Therefore, when the vertical pillar (450-1) is lowered in order to mount and fix the user's ankle through the foot rest 400, the height can be adjusted by lowering while compressing the self-propelled airbag 470, and the pressing protrusion 450a is It can be selectively positioned and fixed in the hemisphere groove (450b).

Referring to FIG. 7, depending on the position of the step adjustment hole 253 where the rod bracket 254 is coupled through the position fixing part 255, the height at which the user's waist is extended during the extension of the cylinder rod 242 It can be adjusted step by step.

Specifically, as shown in FIG. 7, when the rod bracket 254 is coupled to the first adjustment hole 2531 through the position fixing part 255 (hereinafter, the first step), the cylinder rod 242 is elongated. Even if not, the link section 220 can be positioned at some distance from the first frame 110, and even if the cylinder rod 242 is extended only by a relatively small length, the wheel 221 of the link section 220 is on the ground. It is grounded and the link section 220 is rotated, and the user's waist can be raised and extended.

On the other hand, when the load bracket 254 is coupled to the second adjustment hole 2532 through the position fixing part 255 (hereinafter, the second step), compared to the first step, the link section 220 is the first frame. It can be located more closely to (110), and the cylinder rod 242 must be extended to a greater length compared to the first stage so that the wheel 221 is grounded on the ground and the linkage 220 is rotated to relieve the user's waist. It can be elevated and templed.

On the other hand, as shown in the dotted line in FIG. 7, when the load bracket 254 is coupled to the third adjustment hole 2533 through the position fixing part 255 (hereinafter, the third step), the first step and Compared to the second stage, the link section 220 can be positioned most closely to the first frame 110, and the cylinder rod 242 must be extended to a greater length compared to the second stage so that the wheel 221 is on the ground. It is grounded and the link section 220 is rotated so that the user's waist can be raised and extended.

That is, the positions of the rotating bar 230 and the link section 220 will be different in the preparation stage depending on which position of the plurality of step adjustment holes 253 provided in the rod piece 251 is coupled to the rod bracket 254. As the cylinder rod 242 extends, the user's waist extension height may vary.

Meanwhile, depending on the size of the entire mechanism and the size of the rod piece 251, the maximum number of step adjustment holes 253 that can be formed in the rod piece 251 may be limited, and the front and rear lengths of the rod piece 251 may be limited. If the size is set to a preset size, the range of the coupling position of the rod bracket 254 coupled to the rod piece 251 may also be limited within the preset size range.

Therefore, according to one embodiment of the present invention, the height range at which the user's waist is extended can be further adjusted through the additional adjustment means 300. This operation is explained with reference to FIGS. 8A to 8D. In FIGS. 8A to 8D, it is assumed that the load bracket 254 is coupled to the step adjustment hole 253 at the same position among the plurality of step adjustment holes 253. For example, if three step adjustment holes 253 and three step jaws are formed, the height at which the waist is extended can be adjusted in detail in six steps.

First, as shown in 8a, in the preparation stage, the mat 2 of the first frame 110 and the mat of the second frame 120 have a certain inclination angle by the support part 140 and are attached to the first frame 110. The wheel 113 is supported on the ground.

At this time, the support leg 216 of the waist traction unit 200 and the wheel 221 of the link member 220 are also supported on the ground.

When the user lies down in the above state, the upper body and head are positioned on the mat 2 of the first frame 110, the lower body is positioned on the mat 2 of the second frame 120, and the user's ankles are positioned on the mat 2 of the second frame 120. It is fixed by placing it between the rotating rollers 442 of the foot holder 400.

As shown in Figure 8b, when the lying user turns on the switch unit 132 of the handle unit 130, power is applied to the traction cylinder 240 to extend the cylinder rod 242, and the cylinder rod 242 ) pulls the rotating bar 230 connected to the rod piece 251 and the rod bracket 245.

The rotating bar 230 moves the connected link connecting bar 215 and the link section 220 toward the extension frame 150, that is, forward, and at the same time, the wheel 221 of the link section 220 is in rolling contact with the ground. As the link member 210 rises, and as the link member 210 rises, the first frame 110 connected to the first link piece 211 and the second frame 120 connected to the second link piece 212 It rotates around this link member 210.

By rotating the connection portion of the first frame 110 and the second frame 120, the user's waist can be raised and extended to a preset height while the feet are fixed to the footrest 400.

And, when the guide pin 256 of the cylinder rod 242 moves along the guide long hole 312 of the guide bracket 310 and comes into contact with the first step 325 of the additional adjustment plate 320, it moves within the guide long hole 312. Further forward movement is restricted, and then the traction cylinder 240 is operated additionally, allowing the guide pin 256 of the cylinder rod 242 to move by pushing the guide bracket 310 and the additional adjustment plate 320. Through this, the user's entire body, including the lower body, can be towed while the waist is extended.

If you want to further increase the height of waist extension step by step as described above, refer to Figure 8c.

The lifting cylinder 330 operates to lower the additional control plate 320.

The additional control plate 320 is guided by the lifting guide protrusion 323 inserted into the vertical long hole 322 and the lifting control protrusion 323 inserted into the hanging long hole 344a of the straddling bracket 340. .

Therefore, while the guide bracket 310 is fixed, the additional adjustment plate 320 is lowered to a certain height so that the second step 326 of the guide long hole 312 and the additional adjustment hole 324 is aligned in the longitudinal direction of the cylinder rod 242. are placed on the same line.

When the traction cylinder 240 is operated by the switch unit 132, the guide pin 256 moves forward within the step adjustment hole 324 to the second step 326, and thus the link section 220 This rotation causes the link member 210 to rise. At this time, the distance that the guide pin 256 moves to the second step 326 is formed to be larger than the distance that the guide pin 256 moves to the first step 325, so the link member 210 is raised higher and moves to the first step 325. By rotating the frame 110 and the second frame 120, the user's waist can be raised and extended higher than in FIG. 8B. That is, the height at which the user's waist extends can be adjusted step by step, thereby adjusting the strength of traction.

Thereafter, as the traction cylinder 240 is additionally operated, the extension frame 150 including the foot rest 400 is pulled out from the second frame 120 to a certain length according to the elongation of the cylinder rod 242, thereby extending the user's ankle. In this fixed state, it helps traction of the lower back and helps traction of the whole body. That is, the lower body can be pulled while the waist is extended.

In Figure 8d, the height at which the waist is extended is raised one level, and the switch unit 132 operates the lifting cylinder 330 to lower the additional control plate 320.

The additional control plate 320 is guided by the lifting guide protrusion 323 inserted into the vertical long hole 322 and the lifting control protrusion 323 inserted into the hanging long hole 344a of the straddling bracket 340. .

Therefore, while the guide bracket 310 is fixed, the additional adjustment plate 320 is lowered to a certain height so that the third step 327 of the guide long hole 312 and the step adjustment hole 324 is aligned in the longitudinal direction of the cylinder rod 242. are placed on the same line.

When the traction cylinder 240 is operated by the switch unit 132, the guide pin 256 moves forward within the step adjustment hole 324 to the third step 327, and thus the link section 220 As this rotates, the link member 210 can rise further. At this time, the distance that the guide pin 256 moves to the third step 327 is greater than the distance it moves to the second step 326, so the link member 210 rises relatively higher. By rotating the first frame 110 and the second frame 120, the user's waist can be raised and extended higher than in FIG. 8C.

If the load bracket 254 is coupled to the first adjustment hole 2531 and the guide pin 256 is positioned and moved to the same height as the third step 327, the rising height of the waist can be increased to the maximum. there is.

Thereafter, as the traction cylinder 240 is additionally operated, the extension frame 150 including the foot rest 400 is pulled out from the second frame 120 to a certain length according to the elongation of the cylinder rod 242, thereby extending the user's ankle. In this fixed state, it helps traction of the lower back and helps traction of the whole body. That is, the lower body can be pulled while the waist is extended.

Meanwhile, as described above, when the first frame 110 and the second frame 120 are rotated and discomfort is felt during the traction process of the spine, the user applies palm pressure to the emergency brake button 134 of the handle portion 130. The operation of the traction cylinder 240 can be suddenly stopped by applying.

The return to the original state of the first frame 110 and the second frame 120 is performed in the reverse order, and the rotation bar 230 moves backward due to the compression operation of the cylinder rod 242, retracts the link section 220, and the link member 220 retracts. 210 can be lowered and returned to the preparation stage.

The traction cylinder 240 and the lifting cylinder 330 may be operated by inputting a preset range.

According to the above, the rising height of the waist is adjusted step by step according to the user's request, and the ankles, knees, hip joints, etc. are pulled throughout the body by adjusting the height of the waist extension and the inclination angle, thereby promoting a stretching effect. , For adolescents in their growing years, they can do full-body exercises that stimulate the growth plate.

In particular, the height at which the user's waist is extended can be adjusted in detail in stages according to the user's physical condition, such as the presence or absence of back disease such as lumbar disc pain. effect can be achieved.

In addition, it is equipped with an emergency brake button, making it easy to replace in an emergency, thereby increasing users' trust in the product.
